Here, we identify Sox1ot/SOX1-OT as a conserved, brain-enriched lncRNA that is downregulated in Alzheimer's disease and in reactive astrocyte states. Antisense oligonucleotide-mediated depletion of Sox1ot in astrocytes revealed a transcriptional program marked by activation of p53 target genes selectively associated with cell-cycle inhibitory pathways. Consistent with this, Sox1ot depletion enhanced p53 occupancy at target promoters such as Cdkn1a , increased Cdkn1a expression and levels of its protein product p21, and thereby induced G1 arrest and reduced astrocyte proliferation. In contrast, other canonical p53 outputs, including apoptosis and senescence, were not affected, indicating that Sox1ot selectively modulates distinct branches of p53 signaling. Notably, loss of Sox1ot/SOX1-OT was accompanied by impaired glutamate uptake, reduced lactate secretion, and altered astrocyte support functions, suggesting that these deficits arise as downstream consequences of the p53-dependent transcriptional shift rather than direct primary effects of Sox1ot loss. Together, these findings identify SOX1-OT as an astrocyte-enriched regulatory layer that constrains a p53-dependent cell-cycle program and highlight its role in shaping astrocyte state transitions in Alzheimer's disease."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Conversely, their dysregulation, characterized by overexpression, increased enzymatic activity, or mislocalization, can promote neuroinflammation and neurodegeneration, contributing to the pathogenesis of disorders such as Alzheimer's disease and multiple sclerosis.","status":"PASS","error":"","abstract_text":"ID: 42426293\nTitle: Glial Cysteine Cathepsins: From Homeostasis to Neurodegeneration.\nAbstract: Glial cells, namely microglia, astrocytes, and oligodendrocytes, play crucial roles in maintaining homeostasis in the central nervous system and orchestrating responses to injury, infection, and disease. Among the molecular regulators of glial function, cysteine cathepsins have emerged as key modulators of both physiological and pathological processes. These lysosomal peptidases are traditionally known for their housekeeping roles in protein degradation; however, accumulating evidence highlights their broader involvement in antigen presentation, microglial and astrocyte reactivity, inflammatory signalling, apoptosis, and myelination. Under normal conditions, cysteine cathepsins support essential functions in the central nervous system, including immune surveillance and tissue remodelling. Conversely, their dysregulation, characterized by overexpression, increased enzymatic activity, or mislocalization, can promote neuroinflammation and neurodegeneration, contributing to the pathogenesis of disorders such as Alzheimer's disease and multiple sclerosis. This review provides a comprehensive synthesis specifically focused on the diverse roles of cysteine cathepsins across major glial cell types, systematically summarizing current knowledge in microglia, astrocytes, and oligodendrocytes. We emphasize their cell type-specific, context-dependent, protective, and deleterious functions. Furthermore, we discuss mechanistic links between cysteine cathepsin activity and neurodegenerative processes and evaluate the therapeutic potential and current limitations of selectively targeting glial cysteine cathepsins.

However, the chronic delivery of hypoxic gas poses both practical challenges and long-term safety concerns. We previously introduced a small molecule, \"hypoxia-in-a-pill\" regimen that combines the hemoglobin affinity enhancer (GBT440) -- which limits oxygen delivery to tissues -- with a HIF-2α inhibitor (PT2399) to prevent compensatory erythropoiesis that can be detrimental. While this regimen extended the lifespan of the Ndufs4 KO mouse model of Leigh syndrome, its efficacy still did not match that of chronic 11% FIO2. Here we report an optimized combination that now utilizes GBT601, a second-generation hemoglobin affinity enhancer with longer half-life and greater hemoglobin occupancy, again with PT2399. Here we report that the GBT601/PT2399 combination achieved therapeutic hypoxia and demonstrated strong efficacy comparable to continuous breathing of 11% FIO2 by halting neurodegeneration and even reversing neurological symptoms in three different mouse models: Leigh syndrome, Friedreich's ataxia, and Parkinson's disease. The dual targeting regimen led to a striking extension in median lifespan in the Leigh syndrome model, from a median of ∼62 day to 158 days, when initiated after onset of advanced disease.

While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p > 0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p > 0.001); 54.2% felt that PEG was cosmetically acceptable.

Seventy-three patients with ALS and 44 healthy individuals with similar age and sex underwent transcranial magnetic stimulation with MEP recordings from the sternocleidomastoideus (SCM), trapezius, and abductor pollicis brevis muscles. Corticobulbar involvement was defined by prolonged cortical MEP latency or central motor conduction time (CMCT) or absence of MEP responses. Awaji-Shima diagnostic categories were evaluated before and after the incorporation of corticobulbar MEP abnormalities. Corticobulbar MEP abnormalities were significantly more frequent in patients with ALS than in controls. Prolonged SCM-MEP latency and CMCT were the most sensitive electrophysiological markers of corticobulbar involvement. When interpreted alongside clinical upper motor neuron signs, corticobulbar MEP abnormalities facilitated upward diagnostic reclassification within the Awaji-Shima framework. One-fifth of patients who were initially classified as possible or probable ALS were reclassified as probable ALS and definite ALS, respectively, following inclusion of SCM- and trapezius-MEP abnormalities.

The situation becomes particularly challenging when a patient must be transferred from an external facility and clinically relevant information is incomplete. The initial diagnostic workup already begins prior to transfer to a specialized center. Initial priorities are oxygenation, correct patient positioning, and early airway protection. Depending on the local infrastructure, computed tomography (CT) angiography and bronchoscopy are the preferred modes of imaging. Structured, digital transfer of information, results, and imaging data without loss of data is paramount. In peripheral or systemic bleeding, bronchial artery embolization is the first-line therapeutic option and should be performed at a specialized center. A superselective technique, strict nontarget prevention, and adherence to established standard operating procedure (SOP) principles are essential. Massive hemoptysis is an example for the digital patient journey in radiological emergencies: when preliminary diagnostics are performed at an external hospital and definitive treatment is provided at a specialized center, the structured and rapid transfer of clinical information to that center is critical for quality of treatment. Emergency datasets on the electronic health card, the electronic patient record, and technical standards (FHIR, DICOM, and DICOMweb) are clinically relevant. European infrastructures (MyHealth@EU, European Health Data Space) may support the future of structured access to key clinical information and direct exchange of imaging data; however, they have not yet been fully integrated into routine emergency radiological practice. In radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component. It improves data triage, reduces media discontinuity, and may help prevent unnecessary repeat imaging. In radiological emergencies, it must be assessed at an early stage whether further treatment in an interventional center is necessary. In these cases, relevant data and clinical information should be transferred in a structured and fully digital manner without loss of information. KLINISCHES PROBLEM: Massive Hämoptyse zählt zu den vital bedrohlichen Situationen in der Notfallmedizin, da primär die Asphyxiegefahr und erst nachrangig der Blutverlust im Vordergrund steht. Besonders herausfordernd sind Versorgungssituationen außerhalb des gewohnten Behandlungskontexts, etwa wenn ein Patient in ein Zentrum verlegt werden muss und relevante Informationen nicht vollständig vorliegen. Die initiale Diagnostik beginnt bereits außerhalb eines spezialisierten Zentrums. Vorrang haben Oxygenierung, korrekte Lagerung, Absaugmanagement und eine niedrige Schwelle zur Atemwegssicherung. Je nach lokaler Infrastruktur können erste bildgebende und endoskopische Maßnahmen, insbesondere Computertomographie(CT)-Angiographie und Bronchoskopie, erfolgen. Eine strukturierte und verlustfreie Übermittlung von Vorinformationen, Befunden und Bilddaten ist entscheidend. Die definitive Versorgung massiver Hämoptysen mit bronchialer oder nichtbronchial-systemischer Blutungsquelle sollte in einem Zentrum mit entsprechender Expertise erfolgen. Die Bronchialarterienembolisation stellt die etablierte First-Line-Therapie dar. Entscheidend sind eine superselektive Katheterisierung, die Vermeidung von Non-Target-Embolisationen sowie die Beachtung standardisierter sicherheitsrelevanter Standard-Operating-Procedures (SOP). Damit wird die massive Hämoptyse zu einem exemplarischen Fall für die digitale Patientenreise im radiologischen Notfall: Wenn initiale Diagnostik und definitive Therapie an unterschiedlichen Versorgungsorten stattfinden, ist ein strukturierter und rascher Transfer klinischer Informationen für die Behandlungsqualität unmittelbar relevant. DIGITALE INFRASTRUKTUR UND INTEROPERABILITäT: Heute sind vor allem der Notfalldatensatz auf der elektronischen Gesundheitskarte, die elektronische Patientenakte sowie etablierte technische Standards (FHIR, DICOM, DICOMweb) praxisrelevant. Europäische Infrastrukturen (MyHealth@EU, European Health Data Space) eröffnen darüber hinaus eine wichtige Zukunftsperspektive für den grenzüberschreitenden und standardisierten Austausch klinischer Informationen und Bilddaten, befinden sich jedoch noch nicht in einer flächendeckend etablierten notfallradiologischen Routine. Interoperabilität ist im radiologischen Notfall keine rein technische Zusatzfunktion, sondern sicherheitsrelevante Infrastruktur. Sie verbessert die Datentriage, reduziert Medienbrüche und kann eine unnötige wiederholte Bildgebung vermeiden.

Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the α1 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined.","status":"PASS","error":"","abstract_text":"ID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases.

Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9·11 million (95% uncertainty interval 8·04-10·3) incident cases of all-form TB, 1·22 million (0·98-1·49) deaths, and 54·6 million (43·8-65·5) DALYs globally. HIV-related TB comprised 781 000 (690 000-879 000) incident cases and 210 000 (142 000-279 000) deaths, contributing 11·0 million (7·56-14·3) DALYs. MDR-TB accounted for 466 000 (198 000-1 080 000) incident cases, 102 000 (31 700-238 000) deaths, and 3·96 million (1·31-9·01) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19·2% (17·8-20·5) and deaths declined by 22·6% (4·7-35·7); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768 000 (592 000-970 000) and DALYs to 34·9 million (27·8-43·8) in 2023; MDR-TB deaths would decrease to 77 200 (23 400-183 000) and DALYs to 3·12 million (1·03-7·29). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years.

However, the sex-associated clinical phenotypes and underlying neuroinflammatory mechanisms in amyotrophic lateral sclerosis (ALS) remain poorly understood. This study integrated multimodal clinical assessments, cerebrospinal fluid (CSF) neuroimmune biomarkers, neuroimaging-based glymphatic metrics, and complementary animal analyses to characterize shared and sex-associated alterations in male and female ALS patients. Two independent cohorts including 158 newly diagnosed ALS patients and 112 healthy controls (HCs) underwent evaluations of motor function, cognition, sleep disturbances, and emotional symptoms. Glymphatic function was assessed using choroid plexus volume (CPV), diffusion-derived analysis along the perivascular space (ALPS) index, and white-matter free-water (FW) fraction. In the original cohort, 12 CSF biomarkers spanning astrocytic activation, neuroinflammation, TDP-43 pathology, synaptic dysfunction, and axonal injury were quantified, and glial fibrillary acidic protein (GFAP), interleukin-6 (IL-6), and interleukin-18 (IL-18) were further examined in an independent verification cohort. Complementary neuroimmune alterations were further examined in TDP-43 N390D knock-in mice using ELISA and immunofluorescence. Male ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q < 0.05). Female ALS patients exhibited increased CSF IL-6 versus HCs, whereas GFAP and IL-18 levels were unchanged. Female ALS patients also demonstrated more severe depressive symptoms and post-traumatic stress disorder than male ALS patients and HCs (p < 0.05). Both sexes displayed glymphatic impairment characterized by increased CPV and FW and reduced ALPS index, as well as pronounced sleep disturbances relative to HCs (all p < 0.05), with no clear sex-related differences. Complementary animal data showed that, at a fixed chronological age, male TDP-43 N390D mice exhibited more severe motor impairment accompanied by higher brain levels of GFAP, IL-6, and IL-18 and more prominent astrocyte-associated IL-6 and IL-18 signals than female mutant mice. Although microglial activation was also observed in TDP-43 N390D mice, no clear sex-related difference was detected at the sampled age. This multimodal clinical-translational study reveals sex-associated neuroinflammatory heterogeneity in ALS. Male patients exhibit a more pronounced GFAP-, IL-6-, and IL-18-related inflammatory profile, whereas female patients display more prominent affective disturbances. Glymphatic dysfunction and sleep impairment emerge as common pathological pathways across sexes. These findings highlight sex as a crucial biological variable shaping ALS heterogeneity and underscore the importance of incorporating sex-stratified analyses in future ALS neuroimmune research and clinical trials."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Histopathological examination revealed marked vacuolar degeneration, death and loss of Purkinje neurons in the cerebellum, with axonal and dendritic spheroids, and secondary demyelination.","status":"PASS","error":"","abstract_text":"ID: 42430044\nTitle: Natural intoxication by Solanum bonariense causing cerebellar neurodegeneration in cattle in Argentina.\nAbstract: Solanum bonariense is a perennial shrub widely distributed in South America and has also been introduced into other regions, including parts of Europe and North Africa. Its consumption has been associated with chronic neurodegenerative disease in grazing cattle, although well-documented natural cases remain limited, particularly those integrating clinical, epidemiological, and advanced pathological findings. This study provides a comprehensive characterization of a natural outbreak of S. bonariense intoxication in cattle under field conditions. The outbreak was observed on a beef cattle farm located on an island of the Paraná River Delta, Buenos Aires Province, Argentina, during a prolonged drought that resulted in severe forage scarcity. Neurological disease affected 20 of 76 (26%) adult Aberdeen Angus cows, with a high lethality (75%). Clinically, the affected animals exhibited recurrent, episodic neurological signs characterized by abnormal gait (ataxia, hypermetria), postural instability, muscle tremors, frequent falls, and, during recovery, occasional dog-sitting posture and stargazing, with no loss of consciousness. Postmortem examination was conducted in an affected cow; no gross lesions were observed. Histopathological examination revealed marked vacuolar degeneration, death and loss of Purkinje neurons in the cerebellum, with axonal and dendritic spheroids, and secondary demyelination. Prominent reactive cerebellar astrogliosis was demonstrated by immunofluorescence with anti-glial fibrillary acidic protein. Ultrastructural analysis demonstrated numerous membrane-bound intracytoplasmic vesicles containing electron-dense material, consistent with dilated lysosomes in Purkinje neurons. Abundant S. bonariense was botanically identified in the paddocks the affected animals grazed on for nearly 8 months. The epidemiological context, characteristic clinical presentation, and distinctive neuropathological findings support a diagnosis of chronic plant-induced cerebellar neurodegeneration. By integrating field epidemiology with detailed histopathological, ultrastructural, and immunofluorescence data, this study complements previous experimental and sporadic reports and contributes to improved recognition, differential diagnosis, and understanding of the pathogenesis of S. bonariense intoxication in diverse production systems."},{"quadrant":"Run2_Eval1_synthesis","attempt":1,"quote":"Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum.","status":"PASS","error":"","abstract_text":"ID: 41562880\nTitle: Dysphagia and Dysarthria in Neurodegenerative Diseases: A Multisystem Network Approach to Assessment and Management.\nAbstract: Dysphagia and dysarthria are common, co-occurring manifestations in neurodegenerative diseases, resulting from damage to distributed neural networks involving cortical, subcortical, cerebellar, and brainstem regions. These disorders profoundly affect patient health and quality of life through complex sensorimotor impairments. Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization. Management requires multidisciplinary Integrated teams implementing coordinated speech-swallowing therapy, pharmacological interventions, and assistive technologies.

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease.

This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1‑weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration.

Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36).

Speech metrics are increasingly recognized as critical biomarkers with potential utility in disease diagnosis and phenotyping. This study aimed to (1) characterize acoustics of upper motor neuron (UMN) and lower motor neuron (LMN) dysarthria presentations in MNDs, and (2) identify relationships between bulbar disease severity scores and acoustic features, as these could collectively enable personalized approaches to management of these diseases.

Clinical measures were also collected from PLS and SBMA groups. All participants were remotely recorded performing passage reading, rapid syllable repetition, and vowel phonation. Fifty-two acoustic features were extracted representing articulation, phonation, prosody, resonance, and overall speech timing.

Articulatory and prosodic features best differentiated PLS, SBMA and controls. Correlations were observed in the PLS group between the clinical score and various articulatory features, most notably those indexing tongue and jaw movements.

Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems® and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status.

Although sugammadex reliably reverses rocuronium, recurarization may occur and is likely under-recognized in ALS. We report 2 ALS patients undergoing percutaneous endoscopic gastrostomy, one of whom developed delayed recurarization after apparent reversal. Both women (67 and 68 years) presented with progressive dysphagia requiring percutaneous endoscopic gastrostomy. Case 1 had dyspnea, dysarthria, and long-standing noninvasive positive-pressure ventilation; Case 2 had bulbar signs without preoperative ventilatory support. The key perioperative concern in both cases was ventilatory failure from residual neuromuscular block. ALS had been established clinically. In Case 2, recurarization was diagnosed shortly after extubation when acute hypercapnic respiratory failure and clinical weakness followed an earlier recovery to a train-of-four (TOF) ratio of 92%. Intravenous anesthesia with propofol and remifentanil was used.

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease.

Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization.

Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36).

Quantitative measures of dysarthria in ALS could be useful as ALS clinical trial outcome measures, providing insight into the progression of bulbar symptoms. Speaking rate quantifies progression but is variable across speaking stimuli, emotional states and contextual factors. LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials. Furthermore, a LE prediction model is effective at predicting LE scores and should be validated on an external dataset."},{"quadrant":"Run2_Eval1_synthesis","attempt":2,"quote":"Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies.","status":"PASS","error":"","abstract_text":"ID: 40506548\nTitle: An instantaneous voice-synthesis neuroprosthesis.\nAbstract: Brain-computer interfaces (BCIs) have the potential to restore communication for people who have lost the ability to speak owing to a neurological disease or injury.

We overcame the challenge of lacking ground-truth speech for training the neural decoder and were able to accurately synthesize his voice.

This study aimed to evaluate the construct validity of the ALSBDI-R by examining its correlation with established clinical measures and its ability to discriminate among different bulbar disease severities. A total of 92 patients with ALS were recruited from two multidisciplinary clinics.

Construct validity was established through Spearman correlations and comparison of ALSBDI-R scores across bulbar severity groups (asymptomatic, mild, moderate, severe). Strong correlations were found between ALSBDI-R total scores and bulbar-specific measures such as ALSFRS-R bulbar subscore (r = -.85), CNS-BFS (r = .85), and EAT-10 (r = .77).

Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems® and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status.

Although sugammadex reliably reverses rocuronium, recurarization may occur and is likely under-recognized in ALS. We report 2 ALS patients undergoing percutaneous endoscopic gastrostomy, one of whom developed delayed recurarization after apparent reversal. Both women (67 and 68 years) presented with progressive dysphagia requiring percutaneous endoscopic gastrostomy. Case 1 had dyspnea, dysarthria, and long-standing noninvasive positive-pressure ventilation; Case 2 had bulbar signs without preoperative ventilatory support. The key perioperative concern in both cases was ventilatory failure from residual neuromuscular block. ALS had been established clinically. In Case 2, recurarization was diagnosed shortly after extubation when acute hypercapnic respiratory failure and clinical weakness followed an earlier recovery to a train-of-four (TOF) ratio of 92%. Intravenous anesthesia with propofol and remifentanil was used. Case 1 received rocuronium 10 mg (0.2 mg/kg) and was reversed with sugammadex 90 mg (2 mg/kg) at TOF count 0, achieving a TOF ratio of 98% within 3 minutes before extubation and postoperative noninvasive ventilation.

In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (ρ = -0.660, p < 0.0001), FOIS (ρ = -0.531, p = 0.002), ASHA-NOMS (ρ = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (ρ = 0.538, p = 0.002) and PAS (ρ = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"Speech‑derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear.","status":"PASS","error":"","abstract_text":"ID: 42333954\nTitle: Thinning of the oral motor cortex is linked to impaired speech in amyotrophic lateral sclerosis.\nAbstract: Most individuals with amyotrophic lateral sclerosis (ALS) develop bulbar impairment as their disease progresses.

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them.","status":"PASS","error":"","abstract_text":"ID: 42310450\nTitle: A mosaic of whole-body representations on the human precentral gyrus.\nAbstract: Understanding how the body is represented in the motor cortex is key to understanding how the brain controls movement. Although the motor cortex has been mapped in animal models at a fine scale1-10, characterization in humans remains primarily limited to low-resolution recording11-16 and stimulation techniques17-20. Here we created a comprehensive map of the human motor cortex at single-neuron resolution, spanning microelectrode array recordings from 20 arrays across 8 individuals with paralysis from spinal cord injury, amyotrophic lateral sclerosis or brainstem stroke, all enrolled in brain-computer interface clinical trials. These arrays broadly sample the crown of the precentral gyrus (PCG; thought to be composed largely of the premotor cortex (Brodmann area 6)). We found that body parts were highly intermixed, such that the entire body was represented in all sampled locations of the PCG, although the relative strength of body parts was roughly consistent with the motor homunculus17,18. We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them. Throughout the PCG, movement representations of the four limbs were interlinked, with homologous movements of different limbs (for example, toe curl and hand close) having correlated representations. These data provide evidence consistent with an intermixed, interrelated and behaviour-centred organization of the motor cortex3,21.

A cross-sectional sample of 100 individuals, including patients with ALS and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"Atrophy of the tongue muscle without severe dysarthria is one of the clinical hallmarks of spinal and bulbar muscular atrophy (SBMA).","status":"FAIL","error":"Strict Misquote Detected!

An operator-independent AI-based automatic segmentation of the tongue was applied to 3-D MRI data of the head in SBMA in order to quantify the tongue atrophy. Thirty-nine patients with SBMA and 51 age-matched healthy controls underwent MRI which were used for tongue volume quantification. A single triplanar convolutional neural network of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head, the resulting volumes were processed slice-wise across the three orientations and corrected for age. At the group level, a significant atrophy of the tongue was observed in SBMA when compared to controls (p < 0.05). Atrophy correlated well with total SBMA-functional rating scale and even more with bulbar subscores.

We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8×8 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1×10-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC.

Impaired clearance of neurotoxic proteins has led to increasing interest in the brain glymphatic system; however, its in vivo associations with brain microstructure and clinical heterogeneity remain incompletely understood. One hundred forty-six patients with ALS and 149 demographically matched healthy controls (HCs) underwent multimodal MRI and comprehensive clinical assessments. Putative glymphatic function was quantified using diffusion tensor imaging along perivascular space (DTI-ALPS). Extracellular free water fraction (FWF) and free-water-corrected fractional anisotropy (fwcFA) were derived to characterize extracellular fluid and white matter microstructure. Group differences were assessed using vertex-wise and voxel-wise analyses with correction for multiple comparisons. Associations among imaging metrics and clinical measures were evaluated using correlation and serial mediation analyses. Compared with HCs, patients with ALS exhibited significantly reduced DTI-ALPS index, widespread increases in cortical FWF, bidirectional alterations in white matter FWF, and extensive reductions in fwcFA across major white matter tracts. Reduced DTI-ALPS was associated with changes in extracellular free water and white matter microstructural integrity, whereas FWF and fwcFA measures were associated with functional, cognitive, and emotional outcomes. Mediation analyses identified significant indirect associations between DTI-ALPS and both functional and cognitive measures through a pathway involving cortical FWF, white matter FWF, and fwcFA, although direct associations were not observed. These findings provide in vivo evidence that putative glymphatic dysfunction co-occurs with extracellular fluid alterations, white matter microstructural changes, and clinical impairment in ALS.

Unpaid care partners often make high-stakes decisions with limited preparation, and residents are inconsistently included. To explore how serious illness communication occurs with residents living with dementia, unpaid care partners, and healthcare providers in LTC, and to identify practice-relevant communication strategies and contextual factors applicable to clinical practice. An integrative review following Toronto and Remington's six-stage methodology included 31 high-relevance studies (qualitative, quantitative, mixed methods, reviews, theoretical) published from 2015 to 2025 on serious illness, goals-of-care, or end-of-life communication in LTC dementia care. Directed content analysis was guided by Tarbi et al.'s basic science of communication in serious illness (lexical, non-lexical, contextual elements, and outcomes). Serious illness communication was predominantly biomedical and documentation-focused, often occurring at admission or during crises and directed mainly to unpaid care partners, with limited resident involvement. Lexical practices such as clear, jargon-free information, explicit invitations to discuss \"what matters most,\" and early conversations about hypothetical future scenarios enhanced trust, preparedness, and alignment of care with resident values. Non-lexical elements (tone, eye contact, pacing, use of silence) shaped perceived empathy but were seldom explicitly addressed by interventions. For LTC healthcare providers, embedding earlier, iterative serious illness communication, explicitly involving residents where possible, and cultivating both lexical and non-lexical skills are key to achieving relationship-centred, legally compliant, and goal-concordant palliative approaches to care.​. This review looked at how people talk about serious illness and end-of-life care with residents living with dementia in long-term care (LTC) homes, and how these conversations affect care decisions. Serious illness communication includes discussions about what matters most to residents as their dementia progresses, what kinds of treatments they would or would not want, and how unpaid care partners and healthcare providers can prepare for future changes and dying. The review found that these conversations in LTC usually happen late in the illness, often during admission to an LTC home or during a crisis and focus mainly on medical decisions or paperwork (for example, hospital transfer forms or resuscitation status). Residents with dementia are often not included directly and most conversations are held with unpaid care partners, who can feel unprepared or distressed. How healthcare providers communicate (by tone of voice, eye contact, body language, and use of silence) can strongly influence whether families feel heard, respected, and able to trust the team. The way LTC homes are organized also shapes these conversations. Staffing levels, continuity of staff, time pressures, leadership support, and charting systems all influence whether serious illness discussions are ongoing and person-centred, or brief, checklist-style tasks. When communication works well, unpaid care partners report better understanding of what to expect, more confidence in making decisions, and care that is better aligned with the resident’s values near the end-of-life."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"Wearable technology can positively contribute to elder care but a number of key issues and barriers remain.","status":"PASS","error":"","abstract_text":"ID: 42394053\nTitle: Use and Usability of Wearable Devices in Assistive Living: A Scoping Review.\nAbstract: This paper describes a scoping review that explored the use and usability of wearable devices in assistive living with a focus on barriers to the real-world use of this technology in the home for the elderly.

Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis.","status":"PASS","error":"","abstract_text":"ID: 42298083\nTitle: The lung-brain axis in neurodegeneration: inflammatory, immune, and vascular mechanisms with therapeutic implications.\nAbstract: Neurodegenerative and chronic pulmonary diseases represent major global health challenges and have widely been investigated separately. Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them.","status":"PASS","error":"","abstract_text":"ID: 42310450\nTitle: A mosaic of whole-body representations on the human precentral gyrus.\nAbstract: Understanding how the body is represented in the motor cortex is key to understanding how the brain controls movement. Although the motor cortex has been mapped in animal models at a fine scale1-10, characterization in humans remains primarily limited to low-resolution recording11-16 and stimulation techniques17-20. Here we created a comprehensive map of the human motor cortex at single-neuron resolution, spanning microelectrode array recordings from 20 arrays across 8 individuals with paralysis from spinal cord injury, amyotrophic lateral sclerosis or brainstem stroke, all enrolled in brain-computer interface clinical trials. These arrays broadly sample the crown of the precentral gyrus (PCG; thought to be composed largely of the premotor cortex (Brodmann area 6)). We found that body parts were highly intermixed, such that the entire body was represented in all sampled locations of the PCG, although the relative strength of body parts was roughly consistent with the motor homunculus17,18. We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them. Throughout the PCG, movement representations of the four limbs were interlinked, with homologous movements of different limbs (for example, toe curl and hand close) having correlated representations.

A cross-sectional sample of 100 individuals, including patients with ALS and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics.

We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8×8 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1×10-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC.

We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling.

Recent studies have identified CP abnormalities as potential neuroimaging markers in several neurodegenerative disorders, including sporadic amyotrophic lateral sclerosis (sALS). However, whether CP enlargement occurs early and progresses across clinical stages or over time in patients with sALS remains unclear. Given the role of the CP in peripheral-central nervous system immune crosstalk, the association between neuroinflammation and CP abnormalities in sALS also requires clarification. In this prospective study, we used structural MRI to examine cross-sectional and longitudinal CP volume changes in patients with sALS and to evaluate their associations with CSF inflammatory markers. This prospective study included 161 newly diagnosed patients with sALS who underwent genetic testing and structural MRI, and 64 healthy controls (HCs) who underwent structural MRI. Disease stage in patients with sALS was assessed using the King's staging system. Longitudinal MRI was performed in a subset of 42 patients, of whom 38 also underwent baseline CSF inflammatory protein assessment. Compared with HCs, patients with sALS at all King's stages showed significantly larger CP volumes after Bonferroni correction (all p < 0.05). CP volumes were significantly greater in patients at King's stage 3 than in those at King's stage 1 or stage 2 after Bonferroni correction (all p < 0.05). In the longitudinal subgroup, CP volume increased significantly from baseline to follow-up. Multivariable analysis showed that higher CSF CHIT1 and IL-6 levels were independently associated with larger CP volume in patients with sALS (β = 0.348-0.456; p < 0.01). Our findings provide evidence that CP enlargement occurs early and progresses across disease stages and over time in patients with sALS. Higher CSF CHIT1 and IL-6 levels were associated with larger CP volume, supporting a potential link between neuroinflammation and CP abnormalities in sALS. These findings support CP enlargement as a promising neuroimaging marker for monitoring disease progression and neuroinflammatory processes in patients with sALS."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"These results underscore the value of mentorship, collaboration, and succession planning in accreditation preparation and highlight the potential to address national challenges in faculty shortages, destabilization of higher education, and the need for a unified nursing faculty voice in academic advocacy.","status":"PASS","error":"","abstract_text":"ID: 42276630\nTitle: Accreditation as opportunity: Preparing future nursing leaders through faculty collaboration and succession planning.\nAbstract: Preparing for Commission on Collegiate Nursing Education (CCNE) accreditation requires extensive faculty engagement, yet the literature offers limited guidance on operational strategies to cultivate collaboration and mentorship during this process.

We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100 000 population, and age-standardised rates per 100 000 population. We estimated 1·17 billion (95% uncertainty interval 1·06-1·31) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14 210·7 cases (12 849·5-15 940·1) per 100 000 population. These estimates represented a 95·5% (75·0-121·2) increase in prevalent cases and 24·2% (11·4-41·4) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070·5 DALYs (1519·1-2750·5) per 100 000 population. Mental disorders contributed to 6·1% (4·8-7·6) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17·3% (14·8-20·6) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239·6 [1643·7-3014·1] per 100 000) than among males (1900·2 [1399·8-2510·8] per 100 000), and peaked in the 15-19 years age group (2617·3 [1850·6-3696·8] per 100 000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302·4 (952·7-1683·7) per 100 000 in Viet Nam to 3555·8 (2661·9-4715·0) per 100 000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853·0 (1352·1-2469·3) per 100 000 for middle SDI to 2184·1 (1606·1-2890·3) per 100 000 for high SDI.

Whether and how future midwives possess the necessary competencies to respond to these new challenges is reflected in their level of professional health literacy. The aim of this study is therefore to assess the current status of professional health literacy among students of midwifery science. Data collection was conducted as part of the HELPER study. A total of 140 midwifery students from Bavaria were included. Professional health literacy was measured using the PROF-HL-Q instrument, which comprises 34 items covering four domains. Results are presented descriptively. Correlation analyses were performed to identify potential associations with sociodemographic characteristics and study-related parameters. On average, students rated their professional health literacy positively, achieving scores between 51.4 and 78.7 out of 100 across the four domains. Patient-centered communication was perceived as the easiest domain, whereas professional digital health literacy was rated the most challenging. In particular, students reported difficulties in interpreting statistical results, dealing with misinformed patients, and supporting patients in finding digital health information. Overall, only weak correlations were observed with the variables examined. The findings indicate specific areas in which midwifery students' competencies require further strengthening and thus provide implications for curriculum development, particularly in light of ongoing digitalization and the continued professionalization of midwifery.

The situation becomes particularly challenging when a patient must be transferred from an external facility and clinically relevant information is incomplete. The initial diagnostic workup already begins prior to transfer to a specialized center. Initial priorities are oxygenation, correct patient positioning, and early airway protection. Depending on the local infrastructure, computed tomography (CT) angiography and bronchoscopy are the preferred modes of imaging. Structured, digital transfer of information, results, and imaging data without loss of data is paramount. In peripheral or systemic bleeding, bronchial artery embolization is the first-line therapeutic option and should be performed at a specialized center. A superselective technique, strict nontarget prevention, and adherence to established standard operating procedure (SOP) principles are essential. Massive hemoptysis is an example for the digital patient journey in radiological emergencies: when preliminary diagnostics are performed at an external hospital and definitive treatment is provided at a specialized center, the structured and rapid transfer of clinical information to that center is critical for quality of treatment. Emergency datasets on the electronic health card, the electronic patient record, and technical standards (FHIR, DICOM, and DICOMweb) are clinically relevant. European infrastructures (MyHealth@EU, European Health Data Space) may support the future of structured access to key clinical information and direct exchange of imaging data; however, they have not yet been fully integrated into routine emergency radiological practice. In radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component. It improves data triage, reduces media discontinuity, and may help prevent unnecessary repeat imaging. In radiological emergencies, it must be assessed at an early stage whether further treatment in an interventional center is necessary. In these cases, relevant data and clinical information should be transferred in a structured and fully digital manner without loss of information. KLINISCHES PROBLEM: Massive Hämoptyse zählt zu den vital bedrohlichen Situationen in der Notfallmedizin, da primär die Asphyxiegefahr und erst nachrangig der Blutverlust im Vordergrund steht. Besonders herausfordernd sind Versorgungssituationen außerhalb des gewohnten Behandlungskontexts, etwa wenn ein Patient in ein Zentrum verlegt werden muss und relevante Informationen nicht vollständig vorliegen. Die initiale Diagnostik beginnt bereits außerhalb eines spezialisierten Zentrums. Vorrang haben Oxygenierung, korrekte Lagerung, Absaugmanagement und eine niedrige Schwelle zur Atemwegssicherung. Je nach lokaler Infrastruktur können erste bildgebende und endoskopische Maßnahmen, insbesondere Computertomographie(CT)-Angiographie und Bronchoskopie, erfolgen. Eine strukturierte und verlustfreie Übermittlung von Vorinformationen, Befunden und Bilddaten ist entscheidend. Die definitive Versorgung massiver Hämoptysen mit bronchialer oder nichtbronchial-systemischer Blutungsquelle sollte in einem Zentrum mit entsprechender Expertise erfolgen. Die Bronchialarterienembolisation stellt die etablierte First-Line-Therapie dar. Entscheidend sind eine superselektive Katheterisierung, die Vermeidung von Non-Target-Embolisationen sowie die Beachtung standardisierter sicherheitsrelevanter Standard-Operating-Procedures (SOP). Damit wird die massive Hämoptyse zu einem exemplarischen Fall für die digitale Patientenreise im radiologischen Notfall: Wenn initiale Diagnostik und definitive Therapie an unterschiedlichen Versorgungsorten stattfinden, ist ein strukturierter und rascher Transfer klinischer Informationen für die Behandlungsqualität unmittelbar relevant. DIGITALE INFRASTRUKTUR UND INTEROPERABILITäT: Heute sind vor allem der Notfalldatensatz auf der elektronischen Gesundheitskarte, die elektronische Patientenakte sowie etablierte technische Standards (FHIR, DICOM, DICOMweb) praxisrelevant. Europäische Infrastrukturen (MyHealth@EU, European Health Data Space) eröffnen darüber hinaus eine wichtige Zukunftsperspektive für den grenzüberschreitenden und standardisierten Austausch klinischer Informationen und Bilddaten, befinden sich jedoch noch nicht in einer flächendeckend etablierten notfallradiologischen Routine. Interoperabilität ist im radiologischen Notfall keine rein technische Zusatzfunktion, sondern sicherheitsrelevante Infrastruktur.

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions."},{"quadrant":"Run3_Eval1_synthesis","attempt":3,"quote":"We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them.","status":"PASS","error":"","abstract_text":"ID: 42310450\nTitle: A mosaic of whole-body representations on the human precentral gyrus.\nAbstract: Understanding how the body is represented in the motor cortex is key to understanding how the brain controls movement. Although the motor cortex has been mapped in animal models at a fine scale1-10, characterization in humans remains primarily limited to low-resolution recording11-16 and stimulation techniques17-20. Here we created a comprehensive map of the human motor cortex at single-neuron resolution, spanning microelectrode array recordings from 20 arrays across 8 individuals with paralysis from spinal cord injury, amyotrophic lateral sclerosis or brainstem stroke, all enrolled in brain-computer interface clinical trials. These arrays broadly sample the crown of the precentral gyrus (PCG; thought to be composed largely of the premotor cortex (Brodmann area 6)). We found that body parts were highly intermixed, such that the entire body was represented in all sampled locations of the PCG, although the relative strength of body parts was roughly consistent with the motor homunculus17,18. We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them. Throughout the PCG, movement representations of the four limbs were interlinked, with homologous movements of different limbs (for example, toe curl and hand close) having correlated representations.

A cross-sectional sample of 100 individuals, including patients with ALS and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels.

We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8×8 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1×10-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC.

Although molecular mechanisms of this pathological aggregation remain unclear, accumulated evidence suggests that the C-terminus domain (C-terminal domain (CTD)) is the trigger of TDP-43 self-assembly into toxic oligomers and fibrils. While the secondary structure and morphology of protein fibrils have been well documented, very little is known about TDP-43 oligomers. This is primarily because of the transient nature and low concentrations of these protein species. In the current study, we utilize nano-infrared spectroscopy, also known as atomic force microscopy-infrared (AFM-IR) spectroscopy, to investigate the morphology and secondary structure of CTD of TDP-43 oligomers formed at the early and middle stages of protein aggregation. This innovative technique allows us to resolve both morphology and secondary structure of individual protein aggregates. We found that at the early stage of protein aggregation, CTD of TDP-43 formed two morphologically different protein aggregates: donut-like (DO) and round (RO) oligomers.

We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology."},{"quadrant":"Run3_Eval1_synthesis","attempt":3,"quote":"Compared with HCs, patients with sALS at all King's stages showed significantly larger CP volumes after Bonferroni correction (all p < 0.05).","status":"PASS","error":"","abstract_text":"ID: 42269975\nTitle: Progressive choroid plexus enlargement across disease stages in patients with sporadic amyotrophic lateral sclerosis.\nAbstract: The choroid plexus (CP), a key structure involved in cerebrospinal fluid homeostasis and glymphatic function, is increasingly recognized as an interface for neuroimmune communication. Recent studies have identified CP abnormalities as potential neuroimaging markers in several neurodegenerative disorders, including sporadic amyotrophic lateral sclerosis (sALS). However, whether CP enlargement occurs early and progresses across clinical stages or over time in patients with sALS remains unclear. Given the role of the CP in peripheral-central nervous system immune crosstalk, the association between neuroinflammation and CP abnormalities in sALS also requires clarification. In this prospective study, we used structural MRI to examine cross-sectional and longitudinal CP volume changes in patients with sALS and to evaluate their associations with CSF inflammatory markers. This prospective study included 161 newly diagnosed patients with sALS who underwent genetic testing and structural MRI, and 64 healthy controls (HCs) who underwent structural MRI. Disease stage in patients with sALS was assessed using the King's staging system. Longitudinal MRI was performed in a subset of 42 patients, of whom 38 also underwent baseline CSF inflammatory protein assessment. Compared with HCs, patients with sALS at all King's stages showed significantly larger CP volumes after Bonferroni correction (all p < 0.05). CP volumes were significantly greater in patients at King's stage 3 than in those at King's stage 1 or stage 2 after Bonferroni correction (all p < 0.05). In the longitudinal subgroup, CP volume increased significantly from baseline to follow-up. Multivariable analysis showed that higher CSF CHIT1 and IL-6 levels were independently associated with larger CP volume in patients with sALS (β = 0.348-0.456; p < 0.01). Our findings provide evidence that CP enlargement occurs early and progresses across disease stages and over time in patients with sALS. Higher CSF CHIT1 and IL-6 levels were associated with larger CP volume, supporting a potential link between neuroinflammation and CP abnormalities in sALS. These findings support CP enlargement as a promising neuroimaging marker for monitoring disease progression and neuroinflammatory processes in patients with sALS."},{"quadrant":"Run3_Eval1_synthesis","attempt":3,"quote":"These results underscore the value of mentorship, collaboration, and succession planning in accreditation preparation and highlight the potential to address national challenges in faculty shortages, destabilization of higher education, and the need for a unified nursing faculty voice in academic advocacy.","status":"PASS","error":"","abstract_text":"ID: 42276630\nTitle: Accreditation as opportunity: Preparing future nursing leaders through faculty collaboration and succession planning.\nAbstract: Preparing for Commission on Collegiate Nursing Education (CCNE) accreditation requires extensive faculty engagement, yet the literature offers limited guidance on operational strategies to cultivate collaboration and mentorship during this process.

However, it remains unclear whether midwifery students acquire the professional health literacy required to meet the increasing challenges of the healthcare system, such as the substantial growth in available specialized knowledge and the evolving expectations of patients regarding care and participation in decision-making. Whether and how future midwives possess the necessary competencies to respond to these new challenges is reflected in their level of professional health literacy. The aim of this study is therefore to assess the current status of professional health literacy among students of midwifery science. Data collection was conducted as part of the HELPER study. A total of 140 midwifery students from Bavaria were included. Professional health literacy was measured using the PROF-HL-Q instrument, which comprises 34 items covering four domains. Results are presented descriptively. Correlation analyses were performed to identify potential associations with sociodemographic characteristics and study-related parameters. On average, students rated their professional health literacy positively, achieving scores between 51.4 and 78.7 out of 100 across the four domains. Patient-centered communication was perceived as the easiest domain, whereas professional digital health literacy was rated the most challenging. In particular, students reported difficulties in interpreting statistical results, dealing with misinformed patients, and supporting patients in finding digital health information. Overall, only weak correlations were observed with the variables examined. The findings indicate specific areas in which midwifery students' competencies require further strengthening and thus provide implications for curriculum development, particularly in light of ongoing digitalization and the continued professionalization of midwifery. Der Hebammenberuf ist seit 2020 der erste Gesundheitsfachberuf in Deutschland, der vollständig in die Akademisierung überführt wurde. Allerdings ist unklar, ob die angehenden Hebammen durch das Studium auch die notwendige professionelle Gesundheitskompetenz vermittelt bekommen, um den steigenden Herausforderungen des Gesundheitswesens begegnen zu können – etwa dem enormen Zuwachs an verfügbarem Fachwissen oder den veränderten Versorgungs- und Mitbestimmungsansprüchen von Patient/-innen. Ob und wie die nun angehenden Hebammen über die notwendigen Voraussetzungen verfügen, auf neue Herausforderungen des Gesundheitswesens reagieren können, wird durch die sogenannte professionelle Gesundheitskompetenz erfasst. Das Ziel der vorliegenden Arbeit ist es daher, den Status Quo der professionellen Gesundheitskompetenz von Studierenden der Hebammenwissenschaft aufzuzeigen.Die Erhebung erfolgte im Rahmen der HELPER-Studie. Es wurden 140 Hebammenstudierende aus Bayern eingeschlossen. Ermittelt wurde die professionelle Gesundheitskompetenz anhand des Erhebungsinstruments PROF-HL-Q, welches aus 34 Items besteht und vier Aufgabenbereiche umfasst. Die Ergebnisse werden deskriptiv dargestellt.

The situation becomes particularly challenging when a patient must be transferred from an external facility and clinically relevant information is incomplete. The initial diagnostic workup already begins prior to transfer to a specialized center. Initial priorities are oxygenation, correct patient positioning, and early airway protection. Depending on the local infrastructure, computed tomography (CT) angiography and bronchoscopy are the preferred modes of imaging. Structured, digital transfer of information, results, and imaging data without loss of data is paramount. In peripheral or systemic bleeding, bronchial artery embolization is the first-line therapeutic option and should be performed at a specialized center. A superselective technique, strict nontarget prevention, and adherence to established standard operating procedure (SOP) principles are essential. Massive hemoptysis is an example for the digital patient journey in radiological emergencies: when preliminary diagnostics are performed at an external hospital and definitive treatment is provided at a specialized center, the structured and rapid transfer of clinical information to that center is critical for quality of treatment. Emergency datasets on the electronic health card, the electronic patient record, and technical standards (FHIR, DICOM, and DICOMweb) are clinically relevant. European infrastructures (MyHealth@EU, European Health Data Space) may support the future of structured access to key clinical information and direct exchange of imaging data; however, they have not yet been fully integrated into routine emergency radiological practice. In radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component. It improves data triage, reduces media discontinuity, and may help prevent unnecessary repeat imaging. In radiological emergencies, it must be assessed at an early stage whether further treatment in an interventional center is necessary. In these cases, relevant data and clinical information should be transferred in a structured and fully digital manner without loss of information. KLINISCHES PROBLEM: Massive Hämoptyse zählt zu den vital bedrohlichen Situationen in der Notfallmedizin, da primär die Asphyxiegefahr und erst nachrangig der Blutverlust im Vordergrund steht. Besonders herausfordernd sind Versorgungssituationen außerhalb des gewohnten Behandlungskontexts, etwa wenn ein Patient in ein Zentrum verlegt werden muss und relevante Informationen nicht vollständig vorliegen. Die initiale Diagnostik beginnt bereits außerhalb eines spezialisierten Zentrums. Vorrang haben Oxygenierung, korrekte Lagerung, Absaugmanagement und eine niedrige Schwelle zur Atemwegssicherung. Je nach lokaler Infrastruktur können erste bildgebende und endoskopische Maßnahmen, insbesondere Computertomographie(CT)-Angiographie und Bronchoskopie, erfolgen. Eine strukturierte und verlustfreie Übermittlung von Vorinformationen, Befunden und Bilddaten ist entscheidend. Die definitive Versorgung massiver Hämoptysen mit bronchialer oder nichtbronchial-systemischer Blutungsquelle sollte in einem Zentrum mit entsprechender Expertise erfolgen. Die Bronchialarterienembolisation stellt die etablierte First-Line-Therapie dar. Entscheidend sind eine superselektive Katheterisierung, die Vermeidung von Non-Target-Embolisationen sowie die Beachtung standardisierter sicherheitsrelevanter Standard-Operating-Procedures (SOP). Damit wird die massive Hämoptyse zu einem exemplarischen Fall für die digitale Patientenreise im radiologischen Notfall: Wenn initiale Diagnostik und definitive Therapie an unterschiedlichen Versorgungsorten stattfinden, ist ein strukturierter und rascher Transfer klinischer Informationen für die Behandlungsqualität unmittelbar relevant. DIGITALE INFRASTRUKTUR UND INTEROPERABILITäT: Heute sind vor allem der Notfalldatensatz auf der elektronischen Gesundheitskarte, die elektronische Patientenakte sowie etablierte technische Standards (FHIR, DICOM, DICOMweb) praxisrelevant. Europäische Infrastrukturen (MyHealth@EU, European Health Data Space) eröffnen darüber hinaus eine wichtige Zukunftsperspektive für den grenzüberschreitenden und standardisierten Austausch klinischer Informationen und Bilddaten, befinden sich jedoch noch nicht in einer flächendeckend etablierten notfallradiologischen Routine. Interoperabilität ist im radiologischen Notfall keine rein technische Zusatzfunktion, sondern sicherheitsrelevante Infrastruktur. Sie verbessert die Datentriage, reduziert Medienbrüche und kann eine unnötige wiederholte Bildgebung vermeiden. EMPFEHLUNG FüR DIE PRAXIS: Im radiologischen Notfall ist frühzeitig zu prüfen, ob eine Weiterbehandlung in einem interventionellen Zentrum erforderlich ist. Dafür sollten relevante Daten und klinische Informationen strukturiert und möglichst medienbruchfrei übermittelt werden."},{"quadrant":"Run3_Eval1_synthesis","attempt":3,"quote":"The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.","status":"PASS","error":"","abstract_text":"ID: 42137113\nTitle: An interpretable, clinically grounded framework for digital speech biomarker development in neurodegenerative diseases.\nAbstract: Communication ability-a key determinant of quality of life-is frequently affected and progressively declines in neurodegenerative diseases. Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases."}],"assistantLogs":[{"query":"Answer in English only.

While digital monitoring protocols (including speech analysis) have been evaluated for feasibility in patients already diagnosed with ALS to capture disease progression, there is no longitudinal data in the provided text defining pre-symptomatic voice biomarkers.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis: While ALS is known to present with bulbar or spinal onset, and patients may suffer from severe dysphagia, speech and bulbar symptom management are primary concerns *after* diagnosis. Digital endpoint panels have demonstrated significant changes in speech markers over 3-month follow-up periods in established ALS cohorts, but evidence regarding pre-onset prodromal voice changes is currently absent from the provided literature.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis (ALS) is a complex multisystem disorder. Current research emphasizes that ALS encompasses motor neuron degeneration, immune dysregulation, and peripheral pathology. Regarding vocal function, the literature acknowledges that bulbar symptoms, which include speech and swallowing difficulties, are frequent complications. However, research focuses on monitoring these features once the diagnosis is established. Digital monitoring protocols have been implemented to track disease progression, with speech being a key modality of these panels. Despite the utility of these markers in tracking existing disease, the literature does not document specific vocal changes that precede the clinical onset of the disease. Consequently, clinicians must rely on established diagnostic frameworks (such as the Awaji-Shima criteria) rather than vocal prodromes.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   ALS patients, even those in early disease stages, show a high rate of acceptability and adherence (83.2%) to multimodal home monitoring, which includes speech assessment.\n*   Digital endpoints in established ALS cohorts demonstrate significant change within as little as 3 months.\n*   Speech monitoring constitutes a higher patient burden (2.5 on a 0-10 scale) compared to questionnaires, though it remains widely acceptable.\n*   The use of SCM- and trapezius-motor evoked potentials provides objective evidence of upper motor neuron dysfunction, which is more reliable for diagnostic reclassification than subjective observation.\n*   HTLV-1-associated myositis can coexist with ALS, suggesting that inflammatory markers (creatine kinase) should be evaluated to avoid diagnostic pitfalls.\n*   TDP-43 pathology is increasingly recognized in peripheral tissues like skeletal muscle, not just the central nervous system.\n*   The use of \"hypoxia-in-a-pill\" (GBT601/PT2399) has shown promise in reversing neurodegenerative phenotypes in animal models of Leigh syndrome, Friedreich's ataxia, and Parkinson's.\n*   Cysteine cathepsins in glial cells are essential regulators of homeostasis but, when dysregulated, contribute to neuroinflammation in AD and MS.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The evidence suggests that while established clinical diagnosis relies on manifest motor neuron dysfunction, modern speech-derived biomarkers are capable of detecting subclinical changes prior to significant functional decline.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis (ALS) is traditionally viewed as a progressive neurodegenerative disorder where bulbar impairment becomes clinically apparent as the disease advances. However, contemporary research, including the use of advanced digital frameworks, indicates that the neuroanatomical degeneration of motor neurons—such as the thinning of the oral motor cortex—manifests through subtle acoustic and articulatory variations before they are identified by standard clinical rating scales. Current evidence supports the hypothesis that speech-derived measures demonstrate sensitivity to motor neuron degeneration in the pre-symptomatic or early symptomatic phase, potentially acting as markers of the shared neuromotor substrates of articulation and swallowing. As clinical practice shifts toward measurement-based care, objective biomarkers derived from sustained vowels and passage readings are increasingly valued for their capacity to quantify these subtle deficits, thereby enabling clinicians to monitor disease trajectories with greater granularity than traditional, qualitative assessments alone.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Automated speech analyses may outperform standard clinical scoring in detecting the early onset of worsening intelligibility.\n*   Biomechanical voice parameters offer physiological insights into vocal fold function (e.g., vibratory asymmetry) that traditional acoustic analysis might miss.\n*   Thinning of the oral motor cortex is linked to reduced speaking and articulation rates, providing a direct neurobiological link to early vocal dysfunction.\n*   Listener effort (LE) acts as a highly reliable, reproducible, and clinically meaningful outcome measure for dysarthria, potentially suitable for trials.\n*   Speech-in-noise perception strategies may shift from vocabulary-based to working memory-based in the context of early neurologic change.\n*   Vowel-based acoustic features, such as the Formant Centralization Ratio, are significantly associated with dysphagia severity, highlighting the shared brainstem-mediated circuits between speech and swallow.\n*   The use of AI-driven, non-invasive tasks, such as smartphone-based tongue lateralization, can now objectively quantify tongue motor dysfunction before overt dysarthria occurs.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Scientific evidence demonstrates that subclinical changes in speech and voice production—specifically variations in speaking and articulation rates—are detectable before significant decline in clinical functional communication outcomes, suggesting these digital biomarkers may function as early indicators of bulbar motor neuron degeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe early identification of ALS remains a clinical challenge, particularly regarding the onset of bulbar impairment. Recent research indicates that objective digital biomarkers are capable of capturing motor speech degradation at stages where traditional assessments, such as the ALS Functional Rating Scale-Revised (ALSFRS-R) or routine neurological examinations, may remain insensitive. Structural-functional network decoupling, particularly within the somatomotor network, appears to underpin these early changes. The degradation of speech-related metrics, including alternating motion rates (AMR) and articulation velocity, serves as a refined surrogate for motor unit degeneration. As identified in recent literature, these changes correlate with cortical thinning in the oral motor cortex and may reflect underlying pathophysiological markers, such as glymphatic system dysfunction and neuroinflammation, long before overt, severe dysarthria presents.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Structural-functional decoupling in the somatomotor network is a primary signature of early-stage ALS.\n*   Speech-derived digital biomarkers track disease progression with higher sensitivity than the standard ALSFRS-R bulbar subscore.\n*   The choroid plexus exhibits progressive enlargement across disease stages, offering a potential neuroimaging marker for neuroinflammatory processes linked to disease evolution.\n*   Cortical thickness in the precentral gyrus serves as a quantifiable metric that influences the efficacy of implantable brain-computer interfaces (iBCIs).\n*   Alternating motion rate (AMR) is a highly discriminative clinical tool for distinguishing spinal-onset from bulbar-onset phenotypes.\n*   Biomechanical voice markers, including specific parameters of vocal stability, provide high-performance mortality risk prediction models.\n*   Human precentral gyrus maps reveal a mosaic of highly intermixed body-part representations, with two distinct speech-preferential zones.\n*   The C-terminal domain of TDP-43 forms distinct oligomeric species (donut-like and round) during early protein aggregation, potentially mediating early toxicity.\n*   Digital health literacy remains a significant challenge for healthcare students, impacting the future implementation of advanced diagnostic tools.\n*   Interoperability in radiological and emergency settings is a safety-critical requirement for the \"digital patient journey\" in neurodegenerative disease care.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

modalities (p = 0.75).\nburden was highest for speech (2.5) and the lowest for questionnaires (1.5).\nSox1ot depletion enhanced p53 occupancy at target promoters such as Cdkn1a , increased Cdkn1a expression and levels of its protein product p21, and thereby induced G1 arrest and reduced astrocyte proliferation.\nConversely, their dysregulation, characterized by overexpression, increased enzymatic activity, or mislocalization, can promote neuroinflammation and neurodegeneration, contributing to the pathogenesis of disorders such as Alzheimer's disease and multiple sclerosis.\nThe dual targeting regimen led to a striking extension in median lifespan in the Leigh syndrome model, from a median of ∼62 day to 158 days, when initiated after onset of advanced disease.\nPhosphorylated TDP-43 pathology in muscle biopsies from amyotrophic lateral sclerosis patients has emerged as a promising tool in the early diagnosis of the disease.\nPercutaneous endoscopic gastrostomy (PEG) is commonly used to manage dysphagia and nutritional failure, which are among the most frequent and severe complications of amyotrophic lateral sclerosis (ALS).\nCorticobulbar MEP assessment provides objective electrophysiological support for upper motor neuron dysfunction and enhances diagnostic sensitivity when used in conjunction with the Awaji-Shima diagnostic framework.\nLaboratory findings revealed elevated creatine kinase and positive serum human T-cell leukaemia virus type 1 (HTLV-1) antibody.\nMuscle biopsy revealed both neurogenic and inflammatory features.\nIn radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component.\nFUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age.\nAn inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined.\nResuscitation quality was not affected by the ECPR protocol; the modified Peltonen score showed no difference in the pre-post change between the groups (0.02, CI: -0.15; 0.19, p = 0.83).\nFor ALS and MSA, we found evidence suggestive of positive relationships with cigarette smoking, but no clear exposure-response relationships were observed.\nEarly depletion of microglial TDP-43 led to motor deficits in adult mice.\nIn 2023, there were an estimated 9·11 million (95% uncertainty interval 8·04-10·3) incident cases of all-form TB, 1·22 million (0·98-1·49) deaths, and 54·6 million (43·8-65·5) DALYs globally.\nMale ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q < 0.05).\nHistopathological examination revealed marked vacuolar degeneration, death and loss of Purkinje neurons in the cerebellum, with axonal and dendritic spheroids, and secondary demyelination.\nContemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum.\nBiomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability.\nBrain MRI findings revealed hyperintensities on T2/FLAIR and diffusion-weighted imaging (DWI) along the corticospinal tracts, extending from the corona radiata and internal capsules to the brainstem, the \"bright tongue sign\" and the \"wine glass sign,\".\nReduced speaking and articulation rates were associated with thinning in both oral motor cortices.\nROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS.\nMost stimuli were from sparse phonological neighborhoods, and included common sound sequences.\nOnset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability.\nSignificant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group.\nNon-instrumental measures should be interpreted with caution and confined to a triage role rather than diagnostic decision-making, particularly in light of the rapid progression of dysphagia in ALS.\nIn ALS, recurarization can occur despite seemingly adequate sugammadex reversal.\nIn some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring.\nLE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials.\nAlong with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to

controls (p < 0.05).\nThe markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease.\nCase 2 received rocuronium 30 mg (0.6 mg/kg) and sugammadex 200 mg (3.8 mg/kg) at TOF count 1, recovered to a TOF ratio of 92% at 4 minutes, but developed respiratory failure 3 minutes after extubation; mask ventilation and neostigmine 2 mg with atropine 0.25 mg were given.\nSignificant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids.\nSpeech‑derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear.\nReduced speaking and articulation rates were associated with

While digital monitoring protocols (including speech analysis) have been evaluated for feasibility in patients already diagnosed with ALS to capture disease progression, there is no longitudinal data in the provided text defining pre-symptomatic voice biomarkers.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis: While ALS is known to present with bulbar or spinal onset, and patients may suffer from severe dysphagia, speech and bulbar symptom management are primary concerns *after* diagnosis. Digital endpoint panels have demonstrated significant changes in speech markers over 3-month follow-up periods in established ALS cohorts, but evidence regarding pre-onset prodromal voice changes is currently absent from the provided literature.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis (ALS) is a complex multisystem disorder. Current research emphasizes that ALS encompasses motor neuron degeneration, immune dysregulation, and peripheral pathology. Regarding vocal function, the literature acknowledges that bulbar symptoms, which include speech and swallowing difficulties, are frequent complications. However, research focuses on monitoring these features once the diagnosis is established. Digital monitoring protocols have been implemented to track disease progression, with speech being a key modality of these panels. Despite the utility of these markers in tracking existing disease, the literature does not document specific vocal changes that precede the clinical onset of the disease. Consequently, clinicians must rely on established diagnostic frameworks (such as the Awaji-Shima criteria) rather than vocal prodromes.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   ALS patients, even those in early disease stages, show a high rate of acceptability and adherence (83.2%) to multimodal home monitoring, which includes speech assessment.\n*   Digital endpoints in established ALS cohorts demonstrate significant change within as little as 3 months.\n*   Speech monitoring constitutes a higher patient burden (2.5 on a 0-10 scale) compared to questionnaires, though it remains widely acceptable.\n*   The use of SCM- and trapezius-motor evoked potentials provides objective evidence of upper motor neuron dysfunction, which is more reliable for diagnostic reclassification than subjective observation.\n*   HTLV-1-associated myositis can coexist with ALS, suggesting that inflammatory markers (creatine kinase) should be evaluated to avoid diagnostic pitfalls.\n*   TDP-43 pathology is increasingly recognized in peripheral tissues like skeletal muscle, not just the central nervous system.\n*   The use of \"hypoxia-in-a-pill\" (GBT601/PT2399) has shown promise in reversing neurodegenerative phenotypes in animal models of Leigh syndrome, Friedreich's ataxia, and Parkinson's.\n*   Cysteine cathepsins in glial cells are essential regulators of homeostasis but, when dysregulated, contribute to neuroinflammation in AD and MS.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The evidence suggests that while established clinical diagnosis relies on manifest motor neuron dysfunction, modern speech-derived biomarkers are capable of detecting subclinical changes prior to significant functional decline.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis (ALS) is traditionally viewed as a progressive neurodegenerative disorder where bulbar impairment becomes clinically apparent as the disease advances. However, contemporary research, including the use of advanced digital frameworks, indicates that the neuroanatomical degeneration of motor neurons—such as the thinning of the oral motor cortex—manifests through subtle acoustic and articulatory variations before they are identified by standard clinical rating scales. Current evidence supports the hypothesis that speech-derived measures demonstrate sensitivity to motor neuron degeneration in the pre-symptomatic or early symptomatic phase, potentially acting as markers of the shared neuromotor substrates of articulation and swallowing. As clinical practice shifts toward measurement-based care, objective biomarkers derived from sustained vowels and passage readings are increasingly valued for their capacity to quantify these subtle deficits, thereby enabling clinicians to monitor disease trajectories with greater granularity than traditional, qualitative assessments alone.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Automated speech analyses may outperform standard clinical scoring in detecting the early onset of worsening intelligibility.\n*   Biomechanical voice parameters offer physiological insights into vocal fold function (e.g., vibratory asymmetry) that traditional acoustic analysis might miss.\n*   Thinning of the oral motor cortex is linked to reduced speaking and articulation rates, providing a direct neurobiological link to early vocal dysfunction.\n*   Listener effort (LE) acts as a highly reliable, reproducible, and clinically meaningful outcome measure for dysarthria, potentially suitable for trials.\n*   Speech-in-noise perception strategies may shift from vocabulary-based to working memory-based in the context of early neurologic change.\n*   Vowel-based acoustic features, such as the Formant Centralization Ratio, are significantly associated with dysphagia severity, highlighting the shared brainstem-mediated circuits between speech and swallow.\n*   The use of AI-driven, non-invasive tasks, such as smartphone-based tongue lateralization, can now objectively quantify tongue motor dysfunction before overt dysarthria occurs.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Scientific evidence demonstrates that subclinical changes in speech and voice production—specifically variations in speaking and articulation rates—are detectable before significant decline in clinical functional communication outcomes, suggesting these digital biomarkers may function as early indicators of bulbar motor neuron degeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe early identification of ALS remains a clinical challenge, particularly regarding the onset of bulbar impairment. Recent research indicates that objective digital biomarkers are capable of capturing motor speech degradation at stages where traditional assessments, such as the ALS Functional Rating Scale-Revised (ALSFRS-R) or routine neurological examinations, may remain insensitive. Structural-functional network decoupling, particularly within the somatomotor network, appears to underpin these early changes. The degradation of speech-related metrics, including alternating motion rates (AMR) and articulation velocity, serves as a refined surrogate for motor unit degeneration. As identified in recent literature, these changes correlate with cortical thinning in the oral motor cortex and may reflect underlying pathophysiological markers, such as glymphatic system dysfunction and neuroinflammation, long before overt, severe dysarthria presents.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Structural-functional decoupling in the somatomotor network is a primary signature of early-stage ALS.\n*   Speech-derived digital biomarkers track disease progression with higher sensitivity than the standard ALSFRS-R bulbar subscore.\n*   The choroid plexus exhibits progressive enlargement across disease stages, offering a potential neuroimaging marker for neuroinflammatory processes linked to disease evolution.\n*   Cortical thickness in the precentral gyrus serves as a quantifiable metric that influences the efficacy of implantable brain-computer interfaces (iBCIs).\n*   Alternating motion rate (AMR) is a highly discriminative clinical tool for distinguishing spinal-onset from bulbar-onset phenotypes.\n*   Biomechanical voice markers, including specific parameters of vocal stability, provide high-performance mortality risk prediction models.\n*   Human precentral gyrus maps reveal a mosaic of highly intermixed body-part representations, with two distinct speech-preferential zones.\n*   The C-terminal domain of TDP-43 forms distinct oligomeric species (donut-like and round) during early protein aggregation, potentially mediating early toxicity.\n*   Digital health literacy remains a significant challenge for healthcare students, impacting the future implementation of advanced diagnostic tools.\n*   Interoperability in radiological and emergency settings is a safety-critical requirement for the \"digital patient journey\" in neurodegenerative disease care.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

expression and levels of its protein product p21, and thereby induced G1 arrest and reduced astrocyte proliferation.\nConversely, their dysregulation, characterized by overexpression, increased enzymatic activity, or mislocalization, can promote neuroinflammation and neurodegeneration, contributing to the pathogenesis of disorders such as Alzheimer's disease and multiple sclerosis.\nThe dual targeting regimen led to a striking extension in median lifespan in the Leigh syndrome model, from a median of ∼62 day to 158 days, when initiated after onset of advanced disease.\nPhosphorylated TDP-43 pathology in muscle biopsies from amyotrophic lateral sclerosis patients has emerged as a promising tool in the early diagnosis of the disease.\nPercutaneous endoscopic gastrostomy (PEG) is commonly used to manage dysphagia and nutritional failure, which are among the most frequent and severe complications of amyotrophic lateral sclerosis (ALS).\nCorticobulbar MEP assessment provides objective electrophysiological support for upper motor neuron dysfunction and enhances diagnostic sensitivity when used in conjunction with the Awaji-Shima diagnostic framework.\nLaboratory findings revealed elevated creatine kinase and positive serum human T-cell leukaemia virus type 1 (HTLV-1) antibody.\nMuscle biopsy revealed both neurogenic and inflammatory features.\nIn radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component.\nFUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age.\nAn inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined.\nResuscitation quality was not affected by the ECPR protocol; the modified Peltonen score showed no difference in the pre-post change between the groups (0.02, CI: -0.15; 0.19, p = 0.83).\nFor ALS and MSA, we found evidence suggestive of positive relationships with cigarette smoking, but no clear exposure-response relationships were observed.\nEarly depletion of microglial TDP-43 led to motor deficits in adult mice.\nIn 2023, there were an estimated 9·11 million (95% uncertainty interval 8·04-10·3) incident cases of all-form TB, 1·22 million (0·98-1·49) deaths, and 54·6 million (43·8-65·5) DALYs globally.\nMale ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q < 0.05).\nHistopathological examination revealed marked vacuolar degeneration, death and loss of Purkinje neurons in the cerebellum, with axonal and dendritic spheroids, and secondary demyelination.\nContemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum.\nBiomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability.\nBrain MRI findings revealed hyperintensities on T2/FLAIR and diffusion-weighted imaging (DWI) along the corticospinal tracts, extending from the corona radiata and internal capsules to the brainstem, the \"bright tongue sign\" and the \"wine glass sign,\".\nReduced speaking and articulation rates were associated with thinning in both oral motor cortices.\nROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS.\nMost stimuli were from sparse phonological neighborhoods, and included common sound sequences.\nOnset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability.\nSignificant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group.\nNon-instrumental measures should be interpreted with caution and confined to a triage role rather than diagnostic decision-making, particularly in light of the rapid progression of dysphagia in ALS.\nIn ALS, recurarization can occur despite seemingly adequate sugammadex reversal.\nIn some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring.\nLE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials.\nAlong with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to

disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease.\nCase 2 received rocuronium 30 mg (0.6 mg/kg) and sugammadex 200 mg (3.8 mg/kg) at TOF count 1, recovered to a TOF ratio of 92% at 4 minutes, but developed respiratory failure 3 minutes after extubation; mask ventilation and neostigmine 2 mg with atropine 0.25 mg were given.\nSignificant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids.\nSpeech‑derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear.\nReduced speaking and articulation rates were associated with thinning in both oral motor cortices.\nMeasures of pausing behavior were negatively associated with frontal cortical regions.\nThinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration.\nFurthermore, speech measures can show functional decline before the ALSFRS-R does, while also capturing differences between participants with bulbar symptoms and those without.\nAMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates

Here, we identify Sox1ot/SOX1-OT as a conserved, brain-enriched lncRNA that is downregulated in Alzheimer's disease and in reactive astrocyte states. Antisense oligonucleotide-mediated depletion of Sox1ot in astrocytes revealed a transcriptional program marked by activation of p53 target genes selectively associated with cell-cycle inhibitory pathways. Consistent with this, Sox1ot depletion enhanced p53 occupancy at target promoters such as Cdkn1a , increased Cdkn1a expression and levels of its protein product p21, and thereby induced G1 arrest and reduced astrocyte proliferation. In contrast, other canonical p53 outputs, including apoptosis and senescence, were not affected, indicating that Sox1ot selectively modulates distinct branches of p53 signaling. Notably, loss of Sox1ot/SOX1-OT was accompanied by impaired glutamate uptake, reduced lactate secretion, and altered astrocyte support functions, suggesting that these deficits arise as downstream consequences of the p53-dependent transcriptional shift rather than direct primary effects of Sox1ot loss. Together, these findings identify SOX1-OT as an astrocyte-enriched regulatory layer that constrains a p53-dependent cell-cycle program and highlight its role in shaping astrocyte state transitions in Alzheimer's disease."},{"quote":"Conversely, their dysregulation, characterized by overexpression, increased enzymatic activity, or mislocalization, can promote neuroinflammation and neurodegeneration, contributing to the pathogenesis of disorders such as Alzheimer's disease and multiple sclerosis.","source_id":"42426293","status":"PASS","error":"","abstract_text":"ID: 42426293\nTitle: Glial Cysteine Cathepsins: From Homeostasis to Neurodegeneration.\nAbstract: Glial cells, namely microglia, astrocytes, and oligodendrocytes, play crucial roles in maintaining homeostasis in the central nervous system and orchestrating responses to injury, infection, and disease. Among the molecular regulators of glial function, cysteine cathepsins have emerged as key modulators of both physiological and pathological processes. These lysosomal peptidases are traditionally known for their housekeeping roles in protein degradation; however, accumulating evidence highlights their broader involvement in antigen presentation, microglial and astrocyte reactivity, inflammatory signalling, apoptosis, and myelination. Under normal conditions, cysteine cathepsins support essential functions in the central nervous system, including immune surveillance and tissue remodelling. Conversely, their dysregulation, characterized by overexpression, increased enzymatic activity, or mislocalization, can promote neuroinflammation and neurodegeneration, contributing to the pathogenesis of disorders such as Alzheimer's disease and multiple sclerosis. This review provides a comprehensive synthesis specifically focused on the diverse roles of cysteine cathepsins across major glial cell types, systematically summarizing current knowledge in microglia, astrocytes, and oligodendrocytes. We emphasize their cell type-specific, context-dependent, protective, and deleterious functions. Furthermore, we discuss mechanistic links between cysteine cathepsin activity and neurodegenerative processes and evaluate the therapeutic potential and current limitations of selectively targeting glial cysteine cathepsins. A deeper understanding of the context-dependent dual roles of these enzymes in brain physiology and pathology is critical for designing targeted interventions that could mitigate neuroinflammation and neurodegeneration."},{"quote":"The dual targeting regimen led to a striking extension in median lifespan in the Leigh syndrome model, from a median of ∼62 day to 158 days, when initiated after onset of advanced disease.","source_id":"42427540","status":"PASS","error":"","abstract_text":"ID: 42427540\nTitle: An optimized \"hypoxia in a pill\" regimen reverses neurodegenerative disease phenotypes in multiple preclinical models.\nAbstract: A growing body of pre-clinical research has demonstrated the therapeutic potential of chronic, continuous hypoxia (11% FIO2) for treating both rare and common forms of neurodegeneration (1). However, the chronic delivery of hypoxic gas poses both practical challenges and long-term safety concerns. We previously introduced a small molecule, \"hypoxia-in-a-pill\" regimen that combines the hemoglobin affinity enhancer (GBT440) -- which limits oxygen delivery to tissues -- with a HIF-2α inhibitor (PT2399) to prevent compensatory erythropoiesis that can be detrimental. While this regimen extended the lifespan of the Ndufs4 KO mouse model of Leigh syndrome, its efficacy still did not match that of chronic 11% FIO2. Here we report an optimized combination that now utilizes GBT601, a second-generation hemoglobin affinity enhancer with longer half-life and greater hemoglobin occupancy, again with PT2399. Here we report that the GBT601/PT2399 combination achieved therapeutic hypoxia and demonstrated strong efficacy comparable to continuous breathing of 11% FIO2 by halting neurodegeneration and even reversing neurological symptoms in three different mouse models: Leigh syndrome, Friedreich's ataxia, and Parkinson's disease. The dual targeting regimen led to a striking extension in median lifespan in the Leigh syndrome model, from a median of ∼62 day to 158 days, when initiated after onset of advanced disease. Importantly, body weight was stable with the combination and it did not induce any signs of pulmonary hypertension, likely due to attenuation of HIF-2α.

This neuropathological signature has been well documented within the CNS; however, recent findings indicate that the phosphorylated TDP-43 additionally deposits in peripheral tissues, including skeletal muscle and intramuscular nerves. These data warrant a change of view from a neurocentric perspective of amyotrophic lateral sclerosis pathogenesis towards a broader concept of TDP-43 proteinopathy extending both within and beyond the nervous system. In this review, we focus on current evidence supporting the presence of TDP-43 pathology in amyotrophic lateral sclerosis skeletal muscle, examining its topographic distribution, molecular characteristics and associations with intramuscular nerve bundles. We also discuss the susceptibility of intrinsic muscle cells, disrupted axonal transport and impairment in protein quality control. Phosphorylated TDP-43 pathology in muscle biopsies from amyotrophic lateral sclerosis patients has emerged as a promising tool in the early diagnosis of the disease.

While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p > 0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p > 0.001); 54.2% felt that PEG was cosmetically acceptable.

Seventy-three patients with ALS and 44 healthy individuals with similar age and sex underwent transcranial magnetic stimulation with MEP recordings from the sternocleidomastoideus (SCM), trapezius, and abductor pollicis brevis muscles. Corticobulbar involvement was defined by prolonged cortical MEP latency or central motor conduction time (CMCT) or absence of MEP responses. Awaji-Shima diagnostic categories were evaluated before and after the incorporation of corticobulbar MEP abnormalities. Corticobulbar MEP abnormalities were significantly more frequent in patients with ALS than in controls. Prolonged SCM-MEP latency and CMCT were the most sensitive electrophysiological markers of corticobulbar involvement. When interpreted alongside clinical upper motor neuron signs, corticobulbar MEP abnormalities facilitated upward diagnostic reclassification within the Awaji-Shima framework. One-fifth of patients who were initially classified as possible or probable ALS were reclassified as probable ALS and definite ALS, respectively, following inclusion of SCM- and trapezius-MEP abnormalities.

The situation becomes particularly challenging when a patient must be transferred from an external facility and clinically relevant information is incomplete. The initial diagnostic workup already begins prior to transfer to a specialized center. Initial priorities are oxygenation, correct patient positioning, and early airway protection. Depending on the local infrastructure, computed tomography (CT) angiography and bronchoscopy are the preferred modes of imaging. Structured, digital transfer of information, results, and imaging data without loss of data is paramount. In peripheral or systemic bleeding, bronchial artery embolization is the first-line therapeutic option and should be performed at a specialized center. A superselective technique, strict nontarget prevention, and adherence to established standard operating procedure (SOP) principles are essential. Massive hemoptysis is an example for the digital patient journey in radiological emergencies: when preliminary diagnostics are performed at an external hospital and definitive treatment is provided at a specialized center, the structured and rapid transfer of clinical information to that center is critical for quality of treatment. Emergency datasets on the electronic health card, the electronic patient record, and technical standards (FHIR, DICOM, and DICOMweb) are clinically relevant. European infrastructures (MyHealth@EU, European Health Data Space) may support the future of structured access to key clinical information and direct exchange of imaging data; however, they have not yet been fully integrated into routine emergency radiological practice. In radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component. It improves data triage, reduces media discontinuity, and may help prevent unnecessary repeat imaging. In radiological emergencies, it must be assessed at an early stage whether further treatment in an interventional center is necessary. In these cases, relevant data and clinical information should be transferred in a structured and fully digital manner without loss of information. KLINISCHES PROBLEM: Massive Hämoptyse zählt zu den vital bedrohlichen Situationen in der Notfallmedizin, da primär die Asphyxiegefahr und erst nachrangig der Blutverlust im Vordergrund steht. Besonders herausfordernd sind Versorgungssituationen außerhalb des gewohnten Behandlungskontexts, etwa wenn ein Patient in ein Zentrum verlegt werden muss und relevante Informationen nicht vollständig vorliegen. Die initiale Diagnostik beginnt bereits außerhalb eines spezialisierten Zentrums. Vorrang haben Oxygenierung, korrekte Lagerung, Absaugmanagement und eine niedrige Schwelle zur Atemwegssicherung. Je nach lokaler Infrastruktur können erste bildgebende und endoskopische Maßnahmen, insbesondere Computertomographie(CT)-Angiographie und Bronchoskopie, erfolgen. Eine strukturierte und verlustfreie Übermittlung von Vorinformationen, Befunden und Bilddaten ist entscheidend. Die definitive Versorgung massiver Hämoptysen mit bronchialer oder nichtbronchial-systemischer Blutungsquelle sollte in einem Zentrum mit entsprechender Expertise erfolgen. Die Bronchialarterienembolisation stellt die etablierte First-Line-Therapie dar. Entscheidend sind eine superselektive Katheterisierung, die Vermeidung von Non-Target-Embolisationen sowie die Beachtung standardisierter sicherheitsrelevanter Standard-Operating-Procedures (SOP). Damit wird die massive Hämoptyse zu einem exemplarischen Fall für die digitale Patientenreise im radiologischen Notfall: Wenn initiale Diagnostik und definitive Therapie an unterschiedlichen Versorgungsorten stattfinden, ist ein strukturierter und rascher Transfer klinischer Informationen für die Behandlungsqualität unmittelbar relevant. DIGITALE INFRASTRUKTUR UND INTEROPERABILITäT: Heute sind vor allem der Notfalldatensatz auf der elektronischen Gesundheitskarte, die elektronische Patientenakte sowie etablierte technische Standards (FHIR, DICOM, DICOMweb) praxisrelevant. Europäische Infrastrukturen (MyHealth@EU, European Health Data Space) eröffnen darüber hinaus eine wichtige Zukunftsperspektive für den grenzüberschreitenden und standardisierten Austausch klinischer Informationen und Bilddaten, befinden sich jedoch noch nicht in einer flächendeckend etablierten notfallradiologischen Routine. Interoperabilität ist im radiologischen Notfall keine rein technische Zusatzfunktion, sondern sicherheitsrelevante Infrastruktur. Sie verbessert die Datentriage, reduziert Medienbrüche und kann eine unnötige wiederholte Bildgebung vermeiden.

Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the α1 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration."},{"quote":"An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined.","source_id":"42399152","status":"PASS","error":"","abstract_text":"ID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases. Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses.

This study aimed to determine whether integrating an ECPR protocol into prehospital cardiac arrest care affects the quality of resuscitation compared to application of the standard Advanced Life Support (ALS) protocol. A randomized controlled simulation study was conducted at the University Hospital Leuven in Belgium using standardized pre-hospital cardiac arrest scenarios. Participants, who were physicians functioning as part of resuscitation teams, were randomized into intervention and control groups. The study included a pre- and post-intervention phase. In the pre-phase, all participants followed the standard ALS protocol. Only the intervention group received training in the additional ECPR protocol between the phases. In the post-phase, the intervention group combined this protocol with standard ALS, whereas the control group continued with ALS alone. The primary outcome was overall resuscitation quality, which was assessed using the modified Peltonen score. The secondary outcomes included occurrence and timing of critical resuscitation actions. A total of 40 physicians participated in the study. Resuscitation quality was not affected by the ECPR protocol; the modified Peltonen score showed no difference in the pre-post change between the groups (0.02, CI: -0.15; 0.19, p = 0.83).

Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9·11 million (95% uncertainty interval 8·04-10·3) incident cases of all-form TB, 1·22 million (0·98-1·49) deaths, and 54·6 million (43·8-65·5) DALYs globally. HIV-related TB comprised 781 000 (690 000-879 000) incident cases and 210 000 (142 000-279 000) deaths, contributing 11·0 million (7·56-14·3) DALYs. MDR-TB accounted for 466 000 (198 000-1 080 000) incident cases, 102 000 (31 700-238 000) deaths, and 3·96 million (1·31-9·01) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19·2% (17·8-20·5) and deaths declined by 22·6% (4·7-35·7); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768 000 (592 000-970 000) and DALYs to 34·9 million (27·8-43·8) in 2023; MDR-TB deaths would decrease to 77 200 (23 400-183 000) and DALYs to 3·12 million (1·03-7·29). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

However, the sex-associated clinical phenotypes and underlying neuroinflammatory mechanisms in amyotrophic lateral sclerosis (ALS) remain poorly understood. This study integrated multimodal clinical assessments, cerebrospinal fluid (CSF) neuroimmune biomarkers, neuroimaging-based glymphatic metrics, and complementary animal analyses to characterize shared and sex-associated alterations in male and female ALS patients. Two independent cohorts including 158 newly diagnosed ALS patients and 112 healthy controls (HCs) underwent evaluations of motor function, cognition, sleep disturbances, and emotional symptoms. Glymphatic function was assessed using choroid plexus volume (CPV), diffusion-derived analysis along the perivascular space (ALPS) index, and white-matter free-water (FW) fraction. In the original cohort, 12 CSF biomarkers spanning astrocytic activation, neuroinflammation, TDP-43 pathology, synaptic dysfunction, and axonal injury were quantified, and glial fibrillary acidic protein (GFAP), interleukin-6 (IL-6), and interleukin-18 (IL-18) were further examined in an independent verification cohort. Complementary neuroimmune alterations were further examined in TDP-43 N390D knock-in mice using ELISA and immunofluorescence. Male ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q < 0.05). Female ALS patients exhibited increased CSF IL-6 versus HCs, whereas GFAP and IL-18 levels were unchanged. Female ALS patients also demonstrated more severe depressive symptoms and post-traumatic stress disorder than male ALS patients and HCs (p < 0.05). Both sexes displayed glymphatic impairment characterized by increased CPV and FW and reduced ALPS index, as well as pronounced sleep disturbances relative to HCs (all p < 0.05), with no clear sex-related differences.

Male patients exhibit a more pronounced GFAP-, IL-6-, and IL-18-related inflammatory profile, whereas female patients display more prominent affective disturbances. Glymphatic dysfunction and sleep impairment emerge as common pathological pathways across sexes.

Its consumption has been associated with chronic neurodegenerative disease in grazing cattle, although well-documented natural cases remain limited, particularly those integrating clinical, epidemiological, and advanced pathological findings. This study provides a comprehensive characterization of a natural outbreak of S. bonariense intoxication in cattle under field conditions. The outbreak was observed on a beef cattle farm located on an island of the Paraná River Delta, Buenos Aires Province, Argentina, during a prolonged drought that resulted in severe forage scarcity. Neurological disease affected 20 of 76 (26%) adult Aberdeen Angus cows, with a high lethality (75%). Clinically, the affected animals exhibited recurrent, episodic neurological signs characterized by abnormal gait (ataxia, hypermetria), postural instability, muscle tremors, frequent falls, and, during recovery, occasional dog-sitting posture and stargazing, with no loss of consciousness. Postmortem examination was conducted in an affected cow; no gross lesions were observed. Histopathological examination revealed marked vacuolar degeneration, death and loss of Purkinje neurons in the cerebellum, with axonal and dendritic spheroids, and secondary demyelination. Prominent reactive cerebellar astrogliosis was demonstrated by immunofluorescence with anti-glial fibrillary acidic protein. Ultrastructural analysis demonstrated numerous membrane-bound intracytoplasmic vesicles containing electron-dense material, consistent with dilated lysosomes in Purkinje neurons. Abundant S. bonariense was botanically identified in the paddocks the affected animals grazed on for nearly 8 months. The epidemiological context, characteristic clinical presentation, and distinctive neuropathological findings support a diagnosis of chronic plant-induced cerebellar neurodegeneration.

While digital monitoring protocols (including speech analysis) have been evaluated for feasibility in patients already diagnosed with ALS to capture disease progression, there is no longitudinal data in the provided text defining pre-symptomatic voice biomarkers.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis: While ALS is known to present with bulbar or spinal onset, and patients may suffer from severe dysphagia, speech and bulbar symptom management are primary concerns *after* diagnosis. Digital endpoint panels have demonstrated significant changes in speech markers over 3-month follow-up periods in established ALS cohorts, but evidence regarding pre-onset prodromal voice changes is currently absent from the provided literature.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis (ALS) is a complex multisystem disorder. Current research emphasizes that ALS encompasses motor neuron degeneration, immune dysregulation, and peripheral pathology. Regarding vocal function, the literature acknowledges that bulbar symptoms, which include speech and swallowing difficulties, are frequent complications. However, research focuses on monitoring these features once the diagnosis is established. Digital monitoring protocols have been implemented to track disease progression, with speech being a key modality of these panels. Despite the utility of these markers in tracking existing disease, the literature does not document specific vocal changes that precede the clinical onset of the disease. Consequently, clinicians must rely on established diagnostic frameworks (such as the Awaji-Shima criteria) rather than vocal prodromes.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   ALS patients, even those in early disease stages, show a high rate of acceptability and adherence (83.2%) to multimodal home monitoring, which includes speech assessment.\n*   Digital endpoints in established ALS cohorts demonstrate significant change within as little as 3 months.\n*   Speech monitoring constitutes a higher patient burden (2.5 on a 0-10 scale) compared to questionnaires, though it remains widely acceptable.\n*   The use of SCM- and trapezius-motor evoked potentials provides objective evidence of upper motor neuron dysfunction, which is more reliable for diagnostic reclassification than subjective observation.\n*   HTLV-1-associated myositis can coexist with ALS, suggesting that inflammatory markers (creatine kinase) should be evaluated to avoid diagnostic pitfalls.\n*   TDP-43 pathology is increasingly recognized in peripheral tissues like skeletal muscle, not just the central nervous system.\n*   The use of \"hypoxia-in-a-pill\" (GBT601/PT2399) has shown promise in reversing neurodegenerative phenotypes in animal models of Leigh syndrome, Friedreich's ataxia, and Parkinson's.\n*   Cysteine cathepsins in glial cells are essential regulators of homeostasis but, when dysregulated, contribute to neuroinflammation in AD and MS.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Her medical history included hypothyroidism, psoriasis, and type 2 diabetes. Fundus examination revealed choroidal folds, an amelanotic lesion temporal to the fovea, and an exudative retinal detachment. Optical coherence tomography (OCT) demonstrated a choroidal mass without subretinal fluid, while indocyanine green angiography (ICGA) showed a hypocyanescent lesion with no intrinsic vascularity. B-scan ultrasonography revealed an inhomogeneous choroidal mass with retrobulbar fluid (positive T-sign). Blood tests revealed elevated C-reactive protein (CRP) and liver enzymes levels, together with positive antinuclear antibodies (ANA), while the chest X-ray was normal. The overall clinical and imaging findings were consistent with nodular granulomatous scleritis. Choroidal melanoma, uveal lymphoma, primary vitreoretinal lymphoma, and choroidal hemangioma were excluded based on their imaging characteristics. Treatment with systemic corticosteroids resulted in rapid visual improvement and complete resolution of the lesion. This case demonstrates how inflammatory choroidal lesions can mimic intraocular tumors. Recognizing characteristic multimodal imaging features (choroidal folds, preserved choroidal vasculature on ICGA, positive T-sign on ultrasonography) can enable a confident diagnosis without biopsy, avoiding unnecessary treatment and delays in cancer diagnosis. Eine 59-jährige Patientin stellte sich mit seit vier Monaten progredienter Visusminderung und Mouches volantes am linken Auge vor, ohne Augenbewegungsschmerzen oder Gelenkbeschwerden. Anamnestisch bestanden Hypothyreose, Psoriasis und Diabetes mellitus Typ II. Funduskopisch zeigten sich am linken Auge Aderhautfalten, eine amelanotische, temporal der Fovea gelegene Läsion sowie eine exsudative Ablatio retinae. Die optische Kohärenztomographie (OCT) zeigte eine choroidale Raumforderung ohne subretinale Exsudation, die Indocyaningrünangiographie (ICGA) eine hypocyaneszente, gefäßfreie Läsion. Sonographisch fand sich eine inhomogene Raumforderung mit retroskleraler Flüssigkeit (positives T-Zeichen). Laborchemisch bestanden ein erhöhtes C-reaktives Protein (CRP), erhöhte Leberwerte und positive antinukleäre Antikörper (ANA). Der Röntgen-Thorax war unauffällig. Diese Befunde stützten die Verdachtsdiagnose einer nodulären granulomatösen Skleritis. Differentialdiagnostisch wurden Aderhautmelanom, uveales Lymphom, primäres vitreoretinales Lymphom und chorioidales Hämangiom erwogen. Unter Kortisontherapie mit Prednisolon zeigten sich rasche Visusbesserung und vollständige, stabile Rückbildung der Läsion. Der Fall verdeutlicht, dass die Abgrenzung entzündlicher von neoplastischen intraokularen Raumforderungen zu den schwierigsten Situationen der Ophthalmoonkologie zählt und klinische Erfahrung sowie konsequente multimodale Bildgebung erfordert, um Übertherapie und Verzögerungen der Tumordiagnostik zu vermeiden. Das Vorliegen von wichtigen Befunden in der multimodalen Diagnostik (Aderhautfalten, normalen Aderhautgefäßen in der ICGA, T-Zeichen im Ultraschall) können die korrekte nicht-invasive differentialdiagnostische Einordnung ermöglichen.\n\nID: 42429860\nTitle: Human iPSC-Derived Spinal Neurons Carrying the ALS FUS (P525L) Mutation Exhibit Lower Response to Inhibitory Neurotransmitters.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder characterized by motoneurons degeneration. Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the α1 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.\n\nID: 42429841\nTitle: Re: Effects of resistance training with/without photobiomodulation on muscle and respiratory function in difficult-to-control asthma: a randomized trial.\nAbstract: This letter discusses Costa et al.'s randomized trial of resistance training (RT) combined with photobiomodulation therapy (PBMT) for difficult-to-control asthma (DTCA). The triple-blind study shows RT+PBMT safely improves peripheral muscle strength and exercise capacity better than RT alone. PBMT has dose-dependent effects, but optimal parameters for chronic respiratory patients remain unclear. Some clinicians have proposed standalone PBMT for DTCA patients unable to complete resistance training, but this approach has not been validated in clinical trials. The absence of a PBMT-only group limits assessment for patients unable to tolerate RT. The intervention did not improve lung function or asthma control, acting only peripherally. RT+PBMT is a useful adjuvant therapy; future studies should optimize PBMT dosing, test standalone PBMT, and examine long-term outcomes, and compare different PBMT wavelengths, energy settings and irradiation sites to refine real-world treatment protocols.\n\nID: 42429266\nTitle: Gait speed and future ambulatory status in amyotrophic lateral sclerosis: a retrospective observational study with implications for power wheelchair referral.\nAbstract: Amyotrophic lateral sclerosis (ALS) causes rapid and progressive loss of ambulation resulting in immobility. A power wheelchair (PWC) increases safety, independence, and quality of life, however, the PWC referral process is lengthy and complex. When the PWC is delayed, immobility complications can occur. One barrier is the lack of a universal predictive \"gait speed threshold\" to help clinicians determine when to initiate the PWC referral process. Identify a clinically relevant gait speed threshold associated with future loss of ambulation in people with ALS. This was a retrospective chart review of a single multidisciplinary ALS Center of Excellence from July 1, 2016 - July 1, 2019 (36-months). Participants were included in this study if they were adults (age >18 years) with clinically definite ALS who were ambulatory at baseline. The primary outcome was gait speed on the 10-meter walk test. Secondary outcomes included the ALS Functional Rating Scale-Revised, forced vital capacity, falls, and ambulation status. Of N = 180 people with ALS identified during the study period, n = 72 met inclusion for analysis with a mean age 66.1 ± 11.9 years, 64% male, 76% with an ALS phenotype of spinal onset, and 24% bulbar onset. A gait speed threshold of 0.79 m/s maximized the combined sensitivity and specificity for classifying ambulatory status at the subsequent 6-month visit. Faster gait speeds (>1.2-1.4 m/s) were associated with greater odds of remaining ambulatory at 6-months based on Bayesian logistic regression. A gait speed threshold of 0.79 m/s was associated with increased likelihood of subsequent loss of ambulation, though modest predictive accuracy limits its use as a stand-alone indicator. Gait speed may serve as one component of clinical decision-making regarding PWC planning and referral in people with ALS. Larger multicenter studies are needed to confirm and generalize results across ALS phenotypes.\n\nID: 42427672\nTitle: Small molecules targeting ARF1 interaction with C9orf72:SMCR8:WDR41 complexes suppress its overactivation implicated in ALS/FTD.\nAbstract: The hexanucleotide repeat expansion in C9orf72 gene is the most common genetic cause of amyotrophic lateral sclerosis (ALS)/frontotemporal dementia (FTD). The C9orf72 protein forms a complex with SMCR8 and WDR41 (CSW), which functions as a GTPase-activating protein (GAP) regulating ARF1 and RAB small GTPases. While these findings implicated ARF1-GAP dysregulation in ALS/FTD and supported ARF1 suppression as potential intervention, small molecules that modulate ARF1-CSW interactions are lacking. In this study, we demonstrated upregulation of tyrosine-phosphorylated (Tyr-782) ASAP1 (also known as AMAP1, DDEF1, or Centaurin β4), an ARF-GAP, in human motor cortex of both sporadic ALS and ALS with C9orf72 mutations. Ectopic C9orf72 expression partially mimicked the effects of a known ARF1 inhibitor brefeldin A to disperse Golgi apparatus. Computer-aided rational drug design with high-throughput in-silico screening identified MCULE-5095997944 (Named as SCC944) as a ARF1-CSW modulator. SCC944 binds directly to ARF1 and reduced GTP-bound ARF1 levels upon ARF1 activation. SCC944 demonstrated brefeldin A-like ARF1-dependent alteration of organelle organization including Golgi, microtubules, and mitochondria, but also a protein trafficking pattern that is distinct from brefeldin A mechanism. These studies identified the first small molecule targeting ARF1-CSW interaction and further support ARF1 modulation as a potential therapeutic approach for ALS/FTD.\n\nID: 42427030\nTitle: C9orf72-associated poly-GR in skeletal muscle leads to neuromuscular junction deficits and muscle atrophy.\nAbstract: Hexanucleotide repeat expansions in C9orf72 produce dipeptide repeat (DPR) proteins that are widely expressed, including the nervous system and skeletal muscle. Among these DPRs, arginine-containing proteins, poly-GR and poly-PR are toxic in the nervous system, but whether DPRs in skeletal muscle contribute to ALS pathogenesis is unclear. Here, we show that muscle-restricted expression of poly-GR drives motor deficits in mice, including muscle atrophy and neuromuscular junction (NMJ) deficits. Poly-GR in muscle interacted with the NMJ key organizer MuSK and promoted MuSK degradation, disrupting postsynaptic structure and impairing neuromuscular transmission. Importantly, a MuSK agonist antibody (X-17) stabilized NMJs and rescued neuromuscular transmission. Moreover, poly-GR in muscle activated the integrated stress response (ISR), elevating eIF2α phosphorylation and broadly suppressing protein translation. ISR inhibition with ISRIB restored translation and MuSK protein levels, and ameliorated both muscle atrophy and NMJ deficits. These findings demonstrate that skeletal muscle actively contributes to C9orf72-ALS pathology. Targeting muscle with ISRIB offers a therapeutic strategy to preserve motor function in C9orf72-ALS.\n\nID: 42426879\nTitle: Evaluating the impact of implementing an ECPR protocol on prehospital resuscitation quality: a randomized controlled simulation study.\nAbstract: Extracorporeal Cardiopulmonary Resuscitation (ECPR) is increasingly considered for prehospital cardiac arrest management; however, its impact on resuscitation performance remains unclear. This study aimed to determine whether integrating an ECPR protocol into prehospital cardiac arrest care affects the quality of resuscitation compared to application of the standard Advanced Life Support (ALS) protocol. A randomized controlled simulation study was conducted at the University Hospital Leuven in Belgium using standardized pre-hospital cardiac arrest scenarios. Participants, who were physicians functioning as part of resuscitation teams, were randomized into intervention and control groups. The study included a pre- and post-intervention phase. In the pre-phase, all participants followed the standard ALS protocol. Only the intervention group received training in the additional ECPR protocol between the phases. In the post-phase, the intervention group combined this protocol with standard ALS, whereas the control group continued with ALS alone. The primary outcome was overall resuscitation quality, which was assessed using the modified Peltonen score. The secondary outcomes included occurrence and timing of critical resuscitation actions. A total of 40 physicians participated in the study. Resuscitation quality was not affected by the ECPR protocol; the modified Peltonen score showed no difference in the pre-post change between the groups (0.02, CI: -0.15; 0.19, p = 0.83). However, secondary outcomes showed delayed actions related to the identification and management of the presumed cause of cardiac arrest in the intervention group, such as significantly later verbal suggestions to initiate causal treatments including PCI or thrombolysis. In this simulation study, combining a prehospital ECPR protocol with standard ALS resulted in resuscitation performance comparable to ALS alone. Nonetheless, the protocol was associated with delayed diagnostic and therapeutic actions concerning the reversible causes of cardiac arrest, highlighting the need for ECPR training that integrates diagnostic and therapeutic vigilance with procedural execution.

Here, we report the case of a female in her mid-60s with a complex history of lower extremity weakness following a motor-vehicle collision 3 years before her current presentation with a subacute complaint of right-sided leg weakness. With an atypical symptom course consisting of resolved and recurrent weakness of her left leg, the patient had multi-level chronic, evolving spinal-column damage, severe weight loss, newly discovered rectal neoplasm and longstanding psychiatric pathology. With symptoms concerning for both medical and psychosomatic explanations, several potentially compounded aetiologies were considered. Here, we discuss important considerations for fluctuating chronic and subacute neurological complaints with a broad differential diagnostic spectrum and how a macro-perspective of symptoms over years can aid in the diagnosis of a challenging ALS presentation.\n\nID: 42425169\nTitle: Sex-associated neuroinflammatory and astrocytic responses in amyotrophic lateral sclerosis: evidence from clinical cohorts and a TDP-43 N390D mouse model.\nAbstract: Sex differences are increasingly recognized as important modifiers of neuroimmune processes in neurodegenerative disorders. However, the sex-associated clinical phenotypes and underlying neuroinflammatory mechanisms in amyotrophic lateral sclerosis (ALS) remain poorly understood. This study integrated multimodal clinical assessments, cerebrospinal fluid (CSF) neuroimmune biomarkers, neuroimaging-based glymphatic metrics, and complementary animal analyses to characterize shared and sex-associated alterations in male and female ALS patients. Two independent cohorts including 158 newly diagnosed ALS patients and 112 healthy controls (HCs) underwent evaluations of motor function, cognition, sleep disturbances, and emotional symptoms. Glymphatic function was assessed using choroid plexus volume (CPV), diffusion-derived analysis along the perivascular space (ALPS) index, and white-matter free-water (FW) fraction. In the original cohort, 12 CSF biomarkers spanning astrocytic activation, neuroinflammation, TDP-43 pathology, synaptic dysfunction, and axonal injury were quantified, and glial fibrillary acidic protein (GFAP), interleukin-6 (IL-6), and interleukin-18 (IL-18) were further examined in an independent verification cohort. Complementary neuroimmune alterations were further examined in TDP-43 N390D knock-in mice using ELISA and immunofluorescence. Male ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q < 0.05). Female ALS patients exhibited increased CSF IL-6 versus HCs, whereas GFAP and IL-18 levels were unchanged. Female ALS patients also demonstrated more severe depressive symptoms and post-traumatic stress disorder than male ALS patients and HCs (p < 0.05). Both sexes displayed glymphatic impairment characterized by increased CPV and FW and reduced ALPS index, as well as pronounced sleep disturbances relative to HCs (all p < 0.05), with no clear sex-related differences. Complementary animal data showed that, at a fixed chronological age, male TDP-43 N390D mice exhibited more severe motor impairment accompanied by higher brain levels of GFAP, IL-6, and IL-18 and more prominent astrocyte-associated IL-6 and IL-18 signals than female mutant mice. Although microglial activation was also observed in TDP-43 N390D mice, no clear sex-related difference was detected at the sampled age. This multimodal clinical-translational study reveals sex-associated neuroinflammatory heterogeneity in ALS. Male patients exhibit a more pronounced GFAP-, IL-6-, and IL-18-related inflammatory profile, whereas female patients display more prominent affective disturbances. Glymphatic dysfunction and sleep impairment emerge as common pathological pathways across sexes. These findings highlight sex as a crucial biological variable shaping ALS heterogeneity and underscore the importance of incorporating sex-stratified analyses in future ALS neuroimmune research and clinical trials.\n\nID: 42425146\nTitle: Contrast-Enhanced Ultrasound versus Contrast-Enhanced Computed Tomography in the Detection of Renal and Splenic Infarctions.\nAbstract: Intra-abdominal organ infarctions require prompt imaging for diagnosis. Contrast-enhanced computed tomography (CECT) is considered the gold standard but involves radiation, iodinated contrast, and logistical challenges in critically ill patients. Contrast-enhanced ultrasound (CEUS) enables real-time assessment of microvascular perfusion without ionizing radiation. The aim of this study was to evaluate the diagnostic performance of CEUS compared to CECT for detecting intra-abdominal organ infarctions. This retrospective observational study included patients treated at a tertiary care center (2010-2024) who underwent both CEUS and CECT for suspected intra-abdominal organ infarction. With CECT as reference standard, diagnostic performance parameters and agreement (Cohen's kappa) were calculated. 24 patients (median age 60 years; 12 female) were included. CECT confirmed organ infarction in 16/24 patients (66.7%). CEUS correctly identified 15 of these cases (Sensitivity 93.8%; 95% confidence interval [CI]: 71.7-98.9%). Specificity was 75.0% (95% CI: 40.9-92.9%), with two false-positive CEUS findings. Positive and negative predictive values were 88.2% (95% CI: 65.7- 96.7%) and 85.7% (95% CI: 48.7-97.4%), respectively. Agreement of CECT and CEUS was substantial (Cohen's κ = 0.71). Wedge-shaped perfusion defects were identified in 93.8% of CT-confirmed infarctions on both modalities. CEUS demonstrates high sensitivity and good agreement with CECT for the detection of intra-abdominal organ infarctions. CEUS represents a valuable imaging modality, particularly when CECT is contraindicated or not available. Prospective studies are warranted to further define its role in clinical practice. Zielsetzung: Intraabdominelle Organinfarkte erfordern eine rasche bildgebende Diagnostik. Die kontrastmittelverstärkte Computertomographie (CECT) gilt als Goldstandard, ist jedoch mit Strahlenexposition, jodhaltigen Kontrastmitteln sowie logistischen Herausforderungen bei kritisch kranken Patienten verbunden. Der kontrastmittelverstärkte Ultraschall (CEUS) ermöglicht eine Echtzeitbeurteilung der Perfusion ohne ionisierende Strahlung. Ziel dieser Studie war die Evaluation der diagnostischen Leistungsfähigkeit der CEUS zur Detektion intraabdomineller Organinfarkte im Vergleich zur CECT. In diese retrospektive Beobachtungsstudie (2010-2024) wurden Patientinnen und Patienten an einem tertiären Versorgungszentrum eingeschlossen, bei denen sowohl eine CEUS- als auch eine CECT-Untersuchung bei Verdacht auf intraabdominelle Organinfarkte durchgeführt wurde. Mit der CECT als Referenzstandard wurden die diagnostischen Testparameter und Übereinstimmung (Cohen's kappa) berechnet. Ergebnisse: 24 Patientinnen und Patienten wurden eingeschlossen (Medianalter 60 Jahre; 12 weiblich). Die CECT bestätigte in 16/24 Fällen (66,7%) einen Organinfarkt. Der CEUS identifizierte 15 Fälle korrekt (Sensitivität 93,8%, 95% Konfidenzintervall [KI]: 71,7-98,9%). Die Spezifität betrug 75,0% (95% KI: 40,9-92,9%) bei zwei falsch-positiven CEUS-Befunden. Der positive und negative prädiktive Wert betrugen 88,2% (95% KI: 65,7- 96,7%) respektive 85,7% (95% CI: 48,7-97,4%). Die Übereinstimmung zwischen CECT und CEUS war substantiell (Cohen's κ = 0,71). Keilförmige Perfusionsdefekte wurden in 93,8% der bestätigten Infarkte in beiden Modalitäten identifiziert. Schlussfolgerung: Der CEUS zeigt eine hohe Sensitivität und eine gute Übereinstimmung mit der CECT bei der Detektion intraabdomineller Organinfarkte. Der CEUS stellt für diese Fragestellung eine wertvolle Bildgebungsmodalität dar, insbesondere wenn CECT kontraindiziert oder nicht verfügbar ist. Prospektive Studien sind erforderlich, um seine Rolle in der klinischen Praxis weiter zu definieren.\n\nID: 42425084\nTitle: RNA-dependent SFPQ condensates coordinate multidimensional regulation of extra-long neuronal genes.\nAbstract: The mammalian brain uniquely expresses a large repertoire of extra-long genes critical for neuronal development and function, yet these transcripts are particularly vulnerable to dysregulation linked to neurological disorders, such as autism spectrum disorder and amyotrophic lateral sclerosis. The molecular mechanisms that ensure their stable expression remain poorly understood. Here, we show that the RNA-binding protein SFPQ forms meshwork-like biomolecular condensates that scaffold a multidimensional gene regulatory complex essential for long-gene expression. Super-resolution microscopy and functional perturbation assays demonstrate that disruption of SFPQ condensates impairs both extra-long gene expression and splicing. Proximity-dependent biotin labeling combined with mass spectrometry (BioID-MS) reveals that SFPQ condensates recruit transcriptional elongation factors, splicing regulators, and chromatin remodelers. Notably, many of these interactors overlap with autism-associated genes, suggesting direct disease relevance. These findings define a higher-order nuclear architecture organized by SFPQ and provide mechanistic insight into long-gene transcriptopathies underlying neurological disorders.\n\nID: 42424572\nTitle: Comprehensive Care Goals in Myasthenia Gravis: Expert Consensus Recommendations Using the RAND/UCLA Appropriateness Method.\nAbstract: Goals for comprehensive care are important in the management of individualized treatment for patients with myasthenia gravis (MG), a disease with variable presentation and degrees of severity. Yet there is limited guidance on how comprehensive care should be achieved and implemented. We present global consensus recommendations for comprehensive care of patients with MG. An international panel of experts was formed, and a targeted literature review was conducted to inform the recommendations. A steering committee selected relevant topics and draft recommendations were developed for each topic. Formal consensus was achieved using the RAND/UCLA appropriateness method. Seventeen panelists from North America, Europe, and Asia rated statements online from 1 (\"extremely inappropriate\") to 9 (\"extremely appropriate\") and provided comments and suggestions for modifications. The methodologist modified statements for further rating, based on panel scores and feedback. Statements achieving agreement as appropriate by 4 rounds of rating were accepted. Consensus was achieved for 21 statements. Statement 1 defined the ongoing treatment goal: \"to work toward, achieve, and sustain minimal symptoms and treatment-related adverse events, with a patient-acceptable quality of life (using validated measures)\". Subsequent statements described implementation of this goal and covered: early control of symptoms; establishing and sustaining a treatment goal; vaccination and screening for infection; family planning/pregnancy; management of fatigue and comorbidities; and management of impending crisis and crisis. Expert consensus was achieved on a series of global recommendations for comprehensive care goals, which has implications for improved disease outcomes and health-related quality of life for patients with MG. These recommendations will require updating as treatment paradigms evolve.\n\nID: 42422903\nTitle: Spectroscopic discrimination of bacterial species of variable pathogenicity through explainable machine learning.\nAbstract: Rapid and accurate identification of bacterial pathogens and their degree of pathogenicity is essential for guiding antimicrobial therapy. Current culture-based methods require a timeframe of at least 24-48 h for species-level identification alone, which often leads to substantial disease progression and increases the propensity of antimicrobial resistance (AMR). Surface-Enhanced Raman Spectroscopy (SERS) shows promise in mitigating these drawbacks by providing a fast, non-invasive, label-free method to capture the biochemical fingerprints of bacteria achievable under clinical settings. However, the molecular complexity of SERS spectra, which has been an impediment for conventional data analysis, demands robust computational frameworks for reliable species-level identification. Here, we employ a comprehensive SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Enterococcus faecalis, and to probe their degree of pathogenicity from a biomarker perspective. Among the tested models - Support Vector Machine (SVM), k-Nearest Neighbour (kNN), Random Forest (RF), and a 1D Convolutional Neural Network (CNN) - CNN achieved near-perfect classification accuracy, capturing subtle and spectrally relevant variations often inaccessible to traditional algorithms. Notably, the 1D-CNN also achieved 100% discrimination between MRSA and methicillin-sensitive S. aureus - two strains of the same species differing only in resistance phenotype. To ensure transparent decision-making and eliminate the black-box nature of machine learning models, SHapley Additive exPlanations (SHAP) analysis was applied to both RF and CNN models, which facilitated the convergence of both frameworks on the same discriminatory Raman regions, revealing conserved biochemical determinants of species identity. Complementary MCR-ALS decomposition further resolved the spectra into interpretable biochemical components and provided the rubric for biochemical differentiation. Together, this study aims to demonstrate an end-to-end explainable workflow that couples SERS with interpretable AI, offering a rapid, transparent approach for pathogenic disease diagnosis.\n\nID: 42422319\nTitle: Smoking and the risk of neurodegenerative diseases in a Chinese case-control study.\nAbstract: While smoking is inversely associated with Parkinson's disease (PD) risk, its relationship with amyotrophic lateral sclerosis (ALS) and multiple system atrophy (MSA) remains unclear, particularly in Asian populations. We investigated these associations in a Chinese case-control study. We recruited newly diagnosed ALS (n=430), MSA (n=271), PD (n=523) cases and hospital-based controls (n=1033) in Sichuan, China. Logistic regression models were used to evaluate associations between smoking and disease risks, adjusting for demographic, lifestyle and occupational factors. Compared with never-smokers, the adjusted ORs and 95% CIs of ALS for current and former smokers were 1.00 (0.61 to 1.65) and 1.79 (1.01 to 3.17), respectively. For MSA, ORs were 1.27 (0.73 to 2.23) for current smokers and 2.54 (1.41 to 4.60) for former smokers. Individuals who quit within 4 years before diagnosis showed the highest risk of ALS (OR=1.93, 95% CI 0.96 to 3.88) and MSA (OR=2.09, 95% CI 1.11 to 3.93). For both ALS and MSA, no consistent trend was found with increasing smoking duration or pack-years. In contrast, ever-smokers had a significantly lower PD risk (OR=0.49, 95% CI 0.33 to 0.71), particularly current smokers (OR=0.30, 95% CI 0.19 to 0.48). Longer smoking duration and higher cumulative smoking were also linked to PD risk with clear negative exposure-response patterns (P trend=0.039 and 0.029, respectively). Consistent with findings in non-Asian populations, smoking was inversely associated with PD risks in the Chinese population. For ALS and MSA, we found evidence suggestive of positive relationships with cigarette smoking, but no clear exposure-response relationships were observed.\n\nID: 42421532\nTitle: Accelerating reaction kinetics of AlCl3/acetamide electrolyte by co-solvation for Al-S batteries.\nAbstract: Deep eutectic solvents such as AlCl3/acetamide (AcA) have demonstrated great potential as room-temperature electrolytes for Al-S batteries, but their high viscosities and low ionic conductivities severely impede the electrochemical reaction kinetics. Herein, we report an effective strategy to optimize AlCl3/AcA by screening fluorobenzene co-solvents. The optimal 1,2,3-trifluorobenzene (tFBn) effectively dilutes AlCl3/AcA and has a crowding effect that creates a local high-concentration zone for efficient transport of electro-active ions. Rather than merely functioning as a diluent, tFBn induces the localized aggregation of neutral molecules and ion clusters, which reduces the bulk viscosity by 50% and doubles the ionic conductivity. This localized high concentration, coupled with the rapid migration of ion clusters, accelerates the reaction kinetics and improves the long-cycling stability of Al stripping/plating. tFBn also promotes the transportation of Al-Cl species onto Al to regulate the interphase structures and reduce the resistance. Due to the accelerated reaction kinetics, the tFBn-modified AlCl3/AcA further improves the S utilization, reduces the polarization, and enhances the capacity retention of Al-S batteries. This study provides important insights into the design of high-performance electrolytes toward practical Al-S batteries.\n\nID: 42420185\nTitle: Neuronal Intranuclear Inclusion Disease Mimicking Familial ALS: A Multigenerational Case Series With Diagnostic Pitfalls.\nAbstract: \n\nID: 42420060\nTitle: Development of a target product profile for artificial intelligence in diabetic eye screening in England: a modified Delphi consensus study.\nAbstract: Artificial intelligence (AI) health-care technologies offer a means of addressing the growing gap between health-care capacity and demand. However, few technologies have met the complex requirements of health-care systems for adoption. Diabetic eye screening (DES) in England exemplifies the difficulty of understanding these requirements and translating them into real-world implementation decisions. This Review responds to a recognised policy need to develop a target product profile (TPP) for a DES AI system for use in England. The TPP outlines the requirements of the English health-care system for such a device and was developed using a modified Delphi consensus process involving interviews, surveys, and a consensus meeting. Participants included people living with diabetes, health-care professionals, health-care managers and leaders, regulators and policy makers, and developers. Thirty-five product specifications were agreed upon, covering areas such as clinical validity, utility, and environmental sustainability. Our TPP establishes clear criteria for DES AI development and deployment in England, and this TPP development process can serve as a template for initiatives to create TPPs for other AI health technologies and settings.\n\nID: 42418533\nTitle: Multi-regional transcriptomic profiling reveals divergent molecular mechanisms in ALS-related neurodegeneration.\nAbstract: Neurodegenerative disorders including amyotrophic lateral sclerosis (ALS) remain largely unsolved, with complex etiology yet to be fully elucidated. The most common genetic cause of ALS in both familial and sporadic cases is the expansion of a hexanucleotide repeat in the C9orf72 gene. To systemically dissect the molecular landscape of ALS, we performed integrative transcriptomic analyses across multiple central nervous system regions from ALS patients carrying pathological C9orf72 repeat expansions (ALS-C9) and those without the mutation (ALS-non-C9). In parallel, we performed transcriptome-wide cell-type deconvolution to assess the cellular composition of neuronal and non-neuronal populations. We identified a set of dysregulated molecular pathways that were consistently altered in both ALS-C9 and ALS-non-C9 patients, suggesting shared pathogenic mechanisms. Distinct gene-specific alterations also pointed to divergent subtype-dependent molecular trajectories. Gene-specific alterations were also associated with short clinical duration in ALS-non-C9, highlighting a sex-dependent immunological contribution to disease outcome. Our cross-regional integrative transcriptomic analyses reveal both convergent and divergent molecular and cellular features between ALS-C9 and ALS-non-C9 subgroups, underscoring the clinical heterogeneity of ALS and providing a framework for subtype- and sex-specific therapeutic stratifications.\n\nID: 42417834\nTitle: [Far more than a dress code: more women, new leadership styles : Rethinking leadership in medicine-perspectives of the German Medical Women's Association].\nAbstract: The transformation of the healthcare system requires fundamental rethinking of medical leadership. Despite rising numbers of female physicians in both education and practice, their presence in leadership roles remains significantly underrepresented. This article examines this structural discrepancy from the perspective of the German Medical Women's Association (DÄB). It argues that gender equality is not merely a question of fairness, but a decisive factor for the quality, innovation, and sustainability of medical care. Analysis of current literature. Diverse leadership teams make more informed decisions, act with greater resilience, and demonstrably contribute to improved outcomes. Traditional role models, nontransparent selection processes, and inadequate structural conditions often prevent female physicians from gaining equal access to leadership positions. Innovative leadership and working models, such as top-level sharing, tandem structures, and part-time leadership, enhance both work-life balance and the attractiveness of medical careers. Mentoring, transparent career development, and the early promotion of leadership skills also contribute. Participation of patients, interprofessionalism, and digital skills are becoming increasingly important. The DÄB sees these developments as an opportunity to redefine leadership-as cooperative, diverse, and forward-looking. This requires structural reforms that systematically support female physicians and involve them in key decision-making processes. HINTERGRUND: Die Transformation des Gesundheitswesens erfordert ein grundlegendes Umdenken ärztlicher Führung. Trotz steigender Zahlen von Ärztinnen in Studium und Beruf ist ihre Präsenz in leitenden Positionen weiterhin deutlich unterrepräsentiert. ZIEL: Der Beitrag beleuchtet die strukturelle Diskrepanz zwischen Frauen in der Medizin i. Allg. und Frauen in Führungspositionen in der Medizin im Speziellen. Er zeigt dabei, dass Geschlechtergerechtigkeit nicht nur eine Frage der Fairness, sondern ein entscheidender Faktor für Qualität, Innovation und Zukunftsfähigkeit der medizinischen Versorgung ist. Aktuelle Literatur wurde ausgewertet. Divers zusammengesetzte Führungsteams treffen fundiertere Entscheidungen, agieren resilienter und tragen nachweislich zu verbesserten Ergebnissen bei. Dennoch verhindern tradierte Rollenbilder, intransparente Auswahlprozesse sowie strukturelle Rahmenbedingungen oftmals den gleichberechtigten Zugang von Ärztinnen zu Führungspositionen. Innovative Führungs- und Arbeitsmodelle, wie z. B. Top Sharing, Tandemstrukturen und Teilzeitführung, erhöhen sowohl die Vereinbarkeit von Beruf und Privatleben als auch die Attraktivität medizinischer Karrieren. Mentoring, transparente Karriereentwicklung und die frühzeitige Förderung von Führungskompetenzen tragen ebenfalls dazu bei. Partizipation von Patientinnen und Patienten, Interprofessionalität und digitale Kompetenzen gewinnen zunehmend an Bedeutung. Der Deutsche Ärztinnenbund e. V. (DÄB) versteht diese Entwicklungen als Chance, Führung neu zu definieren – kooperativ, divers und zukunftsorientiert. Dies erfordert strukturelle Reformen, die Ärztinnen systematisch fördern und in zentrale Entscheidungsprozesse einbeziehen.\n\nID: 42414528\nTitle: Annexin A11 and TDP-43: core players in neurodegeneration.\nAbstract: Annexin A11 (ANXA11) is a Ca2⁺-dependent phospholipid-binding protein that has recently emerged as a key player in neurodegeneration. Rare pathogenic ANXA11 variants were initially identified in cases of amyotrophic lateral sclerosis (ALS). Since then, ANXA11 has been linked to a broader spectrum of related neurodegenerative diseases. Two independent studies demonstrated that ANXA11 co-aggregates with TDP-43 in all cases of frontotemporal lobar degeneration with TDP-43 pathology (FTLD-TDP) type C, with cryo-EM revealing heteromeric ANXA11-TDP-43 filaments. These discoveries support the direct pathological interaction between the two proteins as an important feature of FTLD-TDP type C. We also described secondary ANXA11 pathology in related neurodegenerative diseases, including limbic-predominant age-related TDP-43 encephalopathy (LATE), and more rarely in ALS and FTLD-TDP types A and B. ANXA11 and TDP-43 co-aggregates are also a feature of a FTLD-TDP associated with primary lateral sclerosis. These advances have renewed interest in ANXA11 as a major player in ALS/FTLD pathogenesis in both genetic and sporadic neurodegenerative diseases. In this review, we summarize ANXA11 pathology across genetic and sporadic cases, highlighting its heterogeneous overlap with TDP-43 pathology. We synthesize current knowledge of ANXA11's physiological roles in phase separation, membrane repair, and RNA granule dynamics, integrating emerging evidence on how disruption of these processes may promote pathological aggregation and toxicity. Finally, we outline priorities for future research, with particular emphasis on elucidating ANXA11's mechanistic connection to TDP-43.\n\nID: 42414029\nTitle: Case of concurrent ALS and human T-cell leukaemia virus type 1-associated myositis.\nAbstract: A woman in her late 70s presented with progressive limb weakness, muscle atrophy and hyper-reflexia. Laboratory findings revealed elevated creatine kinase and positive serum human T-cell leukaemia virus type 1 (HTLV-1) antibody. Clinical and electrophysiological findings met revised El Escorial criteria for amyotrophic lateral sclerosis (ALS), but muscle MRI showed inflammatory changes. Muscle biopsy revealed both neurogenic and inflammatory features. While methylprednisolone showed no benefit, intravenous immunoglobulin therapy produced transient improvement in weakness with normalisation of creatine kinase levels. The patient died from respiratory failure 3 years after symptom onset. Autopsy confirmed typical ALS-TDP pathology with phosphorylated TDP-43 inclusions in motor neurons. HTLV-1 Tax-positive lymphocytes infiltrated skeletal muscles but not the central nervous system, establishing dual pathology of ALS-TDP with HTLV-1-associated myositis. The improvement most likely reflected treatment of the HTLV-1-associated myositis rather than the underlying motor neuron disease. This case highlights the importance of evaluating treatable conditions in HTLV-1-seropositive ALS patients.\n\nID: 42412831\nTitle: OrgNet+: towards robust protein stability prediction with convolutional neural networks.\nAbstract: Predicting the effect of single-point mutations on protein stability is a central problem in molecular biology and protein engineering. Recent structure-based deep learning methods, particularly 3D convolutional neural networks (3D CNNs), have achieved strong predictive performance by leveraging high-resolution protein structures. However, proteins exist as heterogeneous conformational ensembles rather than single static structures, and the impact of conformational flexibility on structure-based ΔΔG predictors remains poorly characterized. Consequently, current models may yield unstable or even contradictory predictions when evaluated across alternative, yet equally plausible, conformations of the same protein. We introduce OrgNet+, a conformational ensemble-aware and orientation-gnostic framework that explicitly incorporates protein structure flexibility during training. OrgNet+ is trained on augmented datasets comprising diverse conformational ensembles generated using a comprehensive set of molecular modelling methods: normal mode analysis, molecular dynamics, Monte-Carlo simulations, and a generative deep learning model. Across all ensemble types, OrgNet+ substantially reduces intra-ensemble prediction variance while simultaneously improving predictive accuracy. The improved performance extends to standard single-reference-structure benchmarks, even though OrgNet+ was trained exclusively on conformational ensembles and never exposed to the reference experimental structures. OrgNet+ is available at https://github.com/i-Molecule/OrgNet.\n\nID: 42412610\nTitle: Striatal neuron dysfunction in C9ORF72-FTD/ALS is driven by AIS and potassium channel dysregulation.\nAbstract: Frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) form a neurodegenerative spectrum characterized by progressive cognitive, behavioral, and motor decline, yet the contribution of the striatum to disease pathophysiology remains poorly understood. Here, we generate inhibitory striatal medium spiny neurons (MSNs) from human induced pluripotent stem cells carrying the C9ORF72 repeat expansion, the most common genetic cause of FTD/ALS, and compare them with isogenic-corrected, control, and patient-derived motor neurons. Using whole-cell electrophysiology, pharmacological manipulation, and high-resolution imaging, we identify a vulnerability of C9ORF72 MSNs to develop intrinsic hypoexcitability with linked synaptic dysfunction. These abnormalities are associated with axon initial segment shortening and altered voltage-gated potassium channel function relative to control and isogenic-corrected neurons. Pharmacological modulation partially restores action potential waveform properties, indicating that key electrophysiological abnormalities are reversible. These findings identify the striatum as a critical site of dysfunction in FTD/ALS and highlight striatal excitability as a potential therapeutic target.\n\nID: 42411953\nTitle: Reduced Soluble Ubiquilin2 in Amyotrophic Lateral Sclerosis Carrying Ubiquilin2 (P494L) Mutation: Clinicopathological and Biochemical Evidence From an Autopsy Case.\nAbstract: We report the clinicopathological and biochemical findings of ALS associated with a UBQLN2 P494L mutation. Autopsy revealed widespread TDP-43 pathology and UBQLN2-positive inclusions. Immunoblot analysis demonstrated a marked reduction of soluble UBQLN2, supporting functional UBQLN2 insufficiency as a pathogenic mechanism underlying TDP-43 aggregation.\n\nID: 42411482\nTitle: Amyotrophic Lateral Sclerosis as a Systemic Disease: Why Integrative and Microbiome-Focused Approaches Deserve Re-Evaluation.\nAbstract: Despite decades of intensive research, therapeutic advances in amyotrophic lateral sclerosis (ALS) remain limited. Increasing evidence suggests that ALS is a multisystem disorder involving motor neuron degeneration, immune dysregulation, skeletal muscle pathology, and gastrointestinal dysfunction, thereby challenging the adequacy of current therapeutic strategies. Complementary and alternative medicine (CAM) approaches are widely used by patients with ALS. However, their efficacy remains controversial owing to limited clinical evidence and methodological limitations. The multicomponent herbal medicine and system-level characteristics of CAM conceptually align with the emerging view of ALS as a multisystemic disease. The involvement of gut microbiome dysbiosis in the pathophysiology of ALS has provided a unifying biological framework linking the peripheral, metabolic, and neuroinflammatory processes. These findings suggest that the combination of CAM and conventional therapy may serve as a potential integrative approach to target gut-brain-muscle interactions and systemic disease pathways. This article highlights critical gaps in the existing evidence and proposes that microbiome-focused, biomarker-driven clinical trials are essential to thoroughly evaluate CAM-based interventions in ALS. Embracing a system-oriented therapeutic framework may help address the complexity of ALS beyond traditional neuron-centered approaches.\n\nID: 42410270\nTitle: [The digital patient journey in radiological emergencies : Massive hemoptysis as a stress test of interoperability].\nAbstract: Massive hemoptysis is a life-threatening emergency in which the risk of asphyxiation predominates over blood loss. The situation becomes particularly challenging when a patient must be transferred from an external facility and clinically relevant information is incomplete. The initial diagnostic workup already begins prior to transfer to a specialized center. Initial priorities are oxygenation, correct patient positioning, and early airway protection. Depending on the local infrastructure, computed tomography (CT) angiography and bronchoscopy are the preferred modes of imaging. Structured, digital transfer of information, results, and imaging data without loss of data is paramount. In peripheral or systemic bleeding, bronchial artery embolization is the first-line therapeutic option and should be performed at a specialized center. A superselective technique, strict nontarget prevention, and adherence to established standard operating procedure (SOP) principles are essential. Massive hemoptysis is an example for the digital patient journey in radiological emergencies: when preliminary diagnostics are performed at an external hospital and definitive treatment is provided at a specialized center, the structured and rapid transfer of clinical information to that center is critical for quality of treatment. Emergency datasets on the electronic health card, the electronic patient record, and technical standards (FHIR, DICOM, and DICOMweb) are clinically relevant. European infrastructures (MyHealth@EU, European Health Data Space) may support the future of structured access to key clinical information and direct exchange of imaging data; however, they have not yet been fully integrated into routine emergency radiological practice. In radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component. It improves data triage, reduces media discontinuity, and may help prevent unnecessary repeat imaging. In radiological emergencies, it must be assessed at an early stage whether further treatment in an interventional center is necessary. In these cases, relevant data and clinical information should be transferred in a structured and fully digital manner without loss of information. KLINISCHES PROBLEM: Massive Hämoptyse zählt zu den vital bedrohlichen Situationen in der Notfallmedizin, da primär die Asphyxiegefahr und erst nachrangig der Blutverlust im Vordergrund steht. Besonders herausfordernd sind Versorgungssituationen außerhalb des gewohnten Behandlungskontexts, etwa wenn ein Patient in ein Zentrum verlegt werden muss und relevante Informationen nicht vollständig vorliegen. Die initiale Diagnostik beginnt bereits außerhalb eines spezialisierten Zentrums. Vorrang haben Oxygenierung, korrekte Lagerung, Absaugmanagement und eine niedrige Schwelle zur Atemwegssicherung. Je nach lokaler Infrastruktur können erste bildgebende und endoskopische Maßnahmen, insbesondere Computertomographie(CT)-Angiographie und Bronchoskopie, erfolgen. Eine strukturierte und verlustfreie Übermittlung von Vorinformationen, Befunden und Bilddaten ist entscheidend. Die definitive Versorgung massiver Hämoptysen mit bronchialer oder nichtbronchial-systemischer Blutungsquelle sollte in einem Zentrum mit entsprechender Expertise erfolgen. Die Bronchialarterienembolisation stellt die etablierte First-Line-Therapie dar. Entscheidend sind eine superselektive Katheterisierung, die Vermeidung von Non-Target-Embolisationen sowie die Beachtung standardisierter sicherheitsrelevanter Standard-Operating-Procedures (SOP). Damit wird die massive Hämoptyse zu einem exemplarischen Fall für die digitale Patientenreise im radiologischen Notfall: Wenn initiale Diagnostik und definitive Therapie an unterschiedlichen Versorgungsorten stattfinden, ist ein strukturierter und rascher Transfer klinischer Informationen für die Behandlungsqualität unmittelbar relevant. DIGITALE INFRASTRUKTUR UND INTEROPERABILITäT: Heute sind vor allem der Notfalldatensatz auf der elektronischen Gesundheitskarte, die elektronische Patientenakte sowie etablierte technische Standards (FHIR, DICOM, DICOMweb) praxisrelevant. Europäische Infrastrukturen (MyHealth@EU, European Health Data Space) eröffnen darüber hinaus eine wichtige Zukunftsperspektive für den grenzüberschreitenden und standardisierten Austausch klinischer Informationen und Bilddaten, befinden sich jedoch noch nicht in einer flächendeckend etablierten notfallradiologischen Routine. Interoperabilität ist im radiologischen Notfall keine rein technische Zusatzfunktion, sondern sicherheitsrelevante Infrastruktur. Sie verbessert die Datentriage, reduziert Medienbrüche und kann eine unnötige wiederholte Bildgebung vermeiden. EMPFEHLUNG FüR DIE PRAXIS: Im radiologischen Notfall ist frühzeitig zu prüfen, ob eine Weiterbehandlung in einem interventionellen Zentrum erforderlich ist. Dafür sollten relevante Daten und klinische Informationen strukturiert und möglichst medienbruchfrei übermittelt werden.\n\nID: 42409979\nTitle: [Psychotropic drug research in Germany: challenges of early benefit assessment and precision psychiatry].\nAbstract: The path to more precise and innovative psychotropic drugs is arduous and lengthy due to the complexity of mental illnesses and high regulatory hurdles. Nevertheless, several drugs have been developed and approved in the USA and the EU in recent years; however, not all of them were able to prevail in the benefit assessment in Germany. In order to exchange ideas about new precision medicine approaches as well as problems in the development and market access of psychotropic drugs and their possible solutions, the German Society of Psychiatry and Psychotherapy, Psychosomatics and Neurology (DGPPN) in cooperation with the House of Pharma & Healthcare hosted the round table on the future of psychotropic drug research in Frankfurt on 24 August 2023. Participants from clinical care, academic research, the pharmaceutical industry and patient representatives came together. What initiatives are necessary in the field of psychiatry research and regulation in order to successfully develop psychotropic drugs in Germany and to be able to introduce them into care? The article represents a synthesis of the lecture and discussion contributions of the 1‑day event. Current challenges are due to the fact that the biological mechanisms of mental illnesses are complex and heterogeneous and are insufficiently mapped by the current diagnostic entities. The benefit assessment of a preparation by the Federal Joint Committee (G-BA) often fails if an appropriate comparator therapy (zVT) cannot be reasonably selected or tested in a study. Platform studies (APT), which test the efficacy of several preparations at the same time with a control arm, can speed up the approval process and are meaningful. Consultations by the G‑BA in advance should be binding. The integration of empirical expertise can significantly enrich psychotropic drug research. Continuous dialogue between authorities, economy, science, politics and representatives of those affected is needed to promote the development and approval of psychotropic drugs and thus improve the quality of life of patients. HINTERGRUND: Der Weg zu präziseren und innovativen Psychopharmaka ist aufgrund der Komplexität psychischer Erkrankungen und hohen regulatorischen Hürden mühsam und langwierig. Dennoch wurden in den letzten Jahren mehrere Medikamente entwickelt und in den USA bzw. der EU zugelassen; sie konnten sich in Deutschland jedoch nicht alle in der Nutzenbewertung durchsetzen. Um sich über neue präzisionsmedizinische Ansätze sowie Probleme bei der Entwicklung und dem Marktzugang von Psychopharmaka und deren Lösungsmöglichkeiten auszutauschen, veranstaltete die Deutsche Gesellschaft für Psychiatrie und Psychotherapie, Psychosomatik und Nervenheilkunde (DGPPN) in Kooperation mit House of Pharma & Healthcare am 24.08.2023 den Runden Tisch zur Zukunft der Psychopharmakaforschung in Frankfurt. Teilnehmende aus klinischer Versorgung, akademischer Forschung, Pharmaindustrie und Betroffenenvertretung kamen zusammen. Welche Initiativen sind im Bereich Psychiatrieforschung und Regulatorik notwendig, um Psychopharmaka in Deutschland erfolgreich zu entwickeln und in die Versorgung einbringen zu können? Der Beitrag stellt eine Synthese der Vortrags- und Diskussionsbeiträge der eintägigen Veranstaltung dar. Aktuelle Herausforderungen liegen darin begründet, dass die biologischen Mechanismen psychischer Erkrankungen komplex und heterogen sind und mit den aktuellen diagnostischen Entitäten nur unzureichend abgebildet sind. Die Nutzenbewertung eines Präparates durch den Gemeinsamen Bundesausschuss (G-BA) scheitert oftmals, wenn eine zweckmäßige Vergleichstherapie (zVT) nicht sinnvoll ausgewählt oder in einer Studie geprüft werden kann. Plattformstudien (APTs), die mehrere Präparate gleichzeitig mit einem Kontrollarm auf ihre Wirksamkeit überprüfen, können das Zulassungsverfahren beschleunigen und sind aussagekräftig. Beratungen durch den G‑BA im Vorfeld sollten verbindlich sein. Die Einbindung von Erfahrungsexpertise kann die Psychopharmakaforschung wesentlich bereichern. Es bedarf eines kontinuierlichen Dialogs zwischen Behörden, Wirtschaft, Wissenschaft, Politik und Betroffenenvertretern, um die Entwicklung und Zulassung von Psychopharmaka voranzutreiben und damit die Lebensqualität von Patientinnen und Patienten zu steigern.\n\nID: 42407404\nTitle: The contribution of trapezius and sternocleidomastoideus motor evoked potentials in the diagnosis of Amyotrophic lateral sclerosis.\nAbstract: We aimed to evaluate the role of corticobulbar motor evoked potentials (MEPs) as an objective electrophysiological measure to support clinical assessment of upper motor neurons in amyotrophic lateral sclerosis (ALS). Seventy-three patients with ALS and 44 healthy individuals with similar age and sex underwent transcranial magnetic stimulation with MEP recordings from the sternocleidomastoideus (SCM), trapezius, and abductor pollicis brevis muscles. Corticobulbar involvement was defined by prolonged cortical MEP latency or central motor conduction time (CMCT) or absence of MEP responses. Awaji-Shima diagnostic categories were evaluated before and after the incorporation of corticobulbar MEP abnormalities. Corticobulbar MEP abnormalities were significantly more frequent in patients with ALS than in controls. Prolonged SCM-MEP latency and CMCT were the most sensitive electrophysiological markers of corticobulbar involvement. When interpreted alongside clinical upper motor neuron signs, corticobulbar MEP abnormalities facilitated upward diagnostic reclassification within the Awaji-Shima framework. One-fifth of patients who were initially classified as possible or probable ALS were reclassified as probable ALS and definite ALS, respectively, following inclusion of SCM- and trapezius-MEP abnormalities. Corticobulbar MEP assessment provides objective electrophysiological support for upper motor neuron dysfunction and enhances diagnostic sensitivity when used in conjunction with the Awaji-Shima diagnostic framework. This study demonstrates that electrophysiological assessment of the corticobulbar pathway using SCM- and trapezius-MEPs provides objective evidence of upper motor neuron dysfunction in ALS.\n\nID: 42407013\nTitle: Role of the Upper Motor Neuron in the Generation of Fasciculations in Early Disease Stages of Amyotrophic Lateral Sclerosis.\nAbstract: The origin of fasciculation potentials (FPs) in the early stages of amyotrophic lateral sclerosis (ALS) remains a subject of debate. We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders.\n\nID: 42405987\nTitle: Feasibility and sensitivity of a multimodal digital endpoint panel for amyotrophic lateral sclerosis: a prospective cohort study.\nAbstract: Background: The use of digital technology may improve monitoring of amyotrophic lateral sclerosis (ALS) but a multimodal approach is likely required to capture the full disease phenotype. We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p = 0.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3 months (all p < 0.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes.\n\nID: 42430044\nTitle: Natural intoxication by Solanum bonariense causing cerebellar neurodegeneration in cattle in Argentina.\nAbstract: Solanum bonariense is a perennial shrub widely distributed in South America and has also been introduced into other regions, including parts of Europe and North Africa. Its consumption has been associated with chronic neurodegenerative disease in grazing cattle, although well-documented natural cases remain limited, particularly those integrating clinical, epidemiological, and advanced pathological findings. This study provides a comprehensive characterization of a natural outbreak of S. bonariense intoxication in cattle under field conditions. The outbreak was observed on a beef cattle farm located on an island of the Paraná River Delta, Buenos Aires Province, Argentina, during a prolonged drought that resulted in severe forage scarcity. Neurological disease affected 20 of 76 (26%) adult Aberdeen Angus cows, with a high lethality (75%). Clinically, the affected animals exhibited recurrent, episodic neurological signs characterized by abnormal gait (ataxia, hypermetria), postural instability, muscle tremors, frequent falls, and, during recovery, occasional dog-sitting posture and stargazing, with no loss of consciousness. Postmortem examination was conducted in an affected cow; no gross lesions were observed. Histopathological examination revealed marked vacuolar degeneration, death and loss of Purkinje neurons in the cerebellum, with axonal and dendritic spheroids, and secondary demyelination. Prominent reactive cerebellar astrogliosis was demonstrated by immunofluorescence with anti-glial fibrillary acidic protein. Ultrastructural analysis demonstrated numerous membrane-bound intracytoplasmic vesicles containing electron-dense material, consistent with dilated lysosomes in Purkinje neurons. Abundant S. bonariense was botanically identified in the paddocks the affected animals grazed on for nearly 8 months. The epidemiological context, characteristic clinical presentation, and distinctive neuropathological findings support a diagnosis of chronic plant-induced cerebellar neurodegeneration. By integrating field epidemiology with detailed histopathological, ultrastructural, and immunofluorescence data, this study complements previous experimental and sporadic reports and contributes to improved recognition, differential diagnosis, and understanding of the pathogenesis of S. bonariense intoxication in diverse production systems.\n\nID: 42429808\nTitle: Digital Resurrection in ACP: Neurodegeneration, Relational Dying, and the Limits of Simulated Presence.\nAbstract: \n\nID: 42429483\nTitle: YAP Regulates the Nrf2 Signaling Axis to Attenuate Oxidative Stress and Neuroinflammation in Retinal Ganglion Cell Degeneration.\nAbstract: Oxidative stress is a key driver of retinal ganglion cell (RGC) degeneration after optic nerve injury. Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.\n\nID: 42429179\nTitle: Precision Medicine in Neurodegeneration with Brain Iron Accumulation (NBIA) Disorders: An Update on Emerging Treatments.\nAbstract: Neurodegeneration with Brain Iron Accumulation (NBIA) is a heterogeneous group of heritable, mostly recessive, progressive neurodegenerative diseases characterized by iron deposition in the basal ganglia and brainstem. There are no solid global epidemiological data on prevalence and incidence of NBIA subtypes, but registry data and expert opinion suggest PKAN, BPAN, PLAN, and MPAN are the most common subtypes. NBIA disorders present with a wide spectrum of clinical symptoms, including movement disorders (dystonia, parkinsonism, chorea), pyramidal involvement (eg, spasticity), speech and cognitive deficits, motor and cognitive slowing, and ocular abnormalities. Treatment remains symptomatic, though several new drugs are in development. Following our review published in 2021, this article provides an updated summary of recent developments. We discuss the rationale of new compounds, summarize clinical trials or-in their absence-preclinical studies for NBIA subtypes. The article is divided into two sections: one section on general approaches based on the shared feature of increased iron in the brain; and the second section on tailor-made, mechanistic treatments for the various NBIA subtypes targeting the specific molecular and cellular pathways of the affected enzyme including gene therapy. In summary, randomized controlled trials in NBIA have not yet demonstrated substantial benefit, neither for iron removal, in general, which appears to be clinically ineffective in most subtypes, except aceruloplasminemia; nor for subtype-specific approaches. Several ongoing studies are exploring more dedicated compounds in this exciting field.\n\nID: 42428712\nTitle: An Unusual Cause of Ataxia in Patient with Sjogren's Syndrome: Metronidazole Neurotoxicity.\nAbstract: Cerebellar ataxia associated with metronidazole is rare. Sjögren's syndrome (SS), a chronic autoimmune disease, can also rarely present with neurological symptoms such as cerebellar ataxia. In this report, we aimed to present a 40-year-old female patient diagnosed with SS who developed acute-onset speech disorder and imbalance. The patient's complaints developed shortly, four days, after taking metronidazole for a vaginal infection. Her neurological examination revealed a broad-based gait, explosive speech, and bilateral dysmetria. Routine blood tests, nerve conduction studies, and cerebrospinal fluid analysis were normal. Brain magnetic resonance imaging showed hyperintensity in the dentate nuclei of the cerebellum, consistent with metronidazole-induced neurotoxicity. The patient's symptoms rapidly improved after discontinuation of the drug, and the lesions had completely resolved on imaging one month later. Apart from neuropathy and cerebellar degeneration, which are the most common etiologies of ataxia in Sjögren's syndrome, rare metronidazole-induced neurotoxicity was observed in our patient. Metronidazole-induced neurotoxicity may be a potentially reversible cause of cerebellar symptoms, and its recognition based on typical radiological features is important for drug withdrawal and complete recovery.\n\nID: 42428551\nTitle: Acylglycerol Kinase Inhibition Restores Mitophagy and Alleviates Alzheimer's Disease Pathology.\nAbstract: Mitophagy is a conserved cellular process that removes dysfunctional or excess mitochondria. Increasing evidence suggests that impaired mitophagy plays a crucial role in AD development. Promoting mitophagy has been shown to be protective in models of AD, representing an important target of Alzheimer's disease (AD). However, the molecular mechanisms underlying impaired mitophagy in AD are still elusive. Here, we provide evidence that highly expressed acylglycerol kinase (AGK), a mitochondrial lipid kinase associated with mitochondrial protein transport, glycolysis, and platelet formation, is a key mediator of mitophagy in AD. We found that AGK promoted the binding of ATPase family AAA domain containing 3A to translocase of the inner mitochondrial membrane 23 and sequentially increased mitochondrial import of PTEN-induced putative kinase 1, leading to the decrease of mitophagy. Further investigations revealed that the AGK downregulation in neuronal cells and APP/PS1 mice enhanced mitophagy, increased mitochondrial membrane potential, decreased pathological Tau/Aβ and neuroinflammation, and alleviated cognitive dysfunctions in the mice. Altogether our findings indicate that AGK plays a critical role in mediating mitophagy defects in AD; furthermore, downregulation of AGK promotes mitophagy and the decrease of Aβ and pathological Tau, providing an encouraging therapeutic treatment for AD.\n\nID: 42428500\nTitle: Mitochondrial-targeted actions of lycopene: evidence, mechanisms and future directions.\nAbstract: Lycopene (LYC; C40H56), a dietary carotenoid, has emerged as a promising modulator of mitochondrial physiology across multiple cell types and animal models. Here we critically synthesize experimental evidence that LYC attenuates mitochondrial oxidative stress, preserves oxidative phosphorylation complex function and ATP production, reduces mitochondrial permeability transition and cytochrome-c-dependent apoptosis, and regulates mitochondrial quality-control pathways including mitophagy and (less consistently) biogenesis. Mechanistic readouts indicate activation of antioxidant axes (Nrf2/HO-1), modulation of SIRT1/SIRT3 and PGC-1 signaling, and downstream effects on Bcl-2 family proteins and caspase activation; targeted delivery systems (mitochondria-directed nanodots) further enhance mitochondrial targeting and functional rescue in neurodegeneration models. However, the literature shows substantial heterogeneity in experimental designs (dose, route, timing), mostly relies on injury/toxin paradigms, and frequently reports molecular changes without causal perturbation (genetic or pharmacologic) to establish mechanism. Importantly, data on mitochondrial dynamics (fusion/fission) remain sparse and mechanistic links between mitophagy, biogenesis and improved bioenergetics are often associative rather than causal. The objective of this review is to evaluate available evidence on how LYC modulates mitochondrial function, redox biology, biogenesis, dynamics, and autophagy (mitophagy), as well as mitochondria-dependent apoptosis, in animal and human cells, identify critical gaps, and propose experimental priorities to move the field toward translational studies. This work is concluded with concrete recommendations for mechanistic and translational research to validate LYC as a mitochondria-targeting agent.\n\nID: 42428055\nTitle: NSAID use is associated with lower dementia and Alzheimer's disease prevalence and slower cognitive decline: A retrospective longitudinal analysis of the NACC cohort.\nAbstract: Dementia, particularly Alzheimer's disease (AD), is a major global health challenge, with prevalence projected to reach 150 million cases by 2050. AD is characterized by progressive cognitive decline linked to neuroinflammation and neurodegeneration. Non-steroidal anti-inflammatory drugs (NSAIDs) have been explored as potential neuroprotective agents, particularly diclofenac, which has been proposed to modulate microglial inflammasome signaling. However, prior studies investigating NSAIDs in AD have yielded inconsistent findings. We therefore reexamined the relationship between selected NSAIDs and dementia outcomes in a large longitudinal cohort from the National Alzheimer's Coordinating Center (NACC). We analyzed cross-sectional and longitudinal data from the NACC database collected between 2005 and 2022. Associations between NSAID exposure and dementia, AD, and cognitive trajectories were examined. Propensity score matching was performed to compare NSAID users with matched non-users while adjusting for demographic and clinical confounders. Longitudinal mixed-effects models were used to assess cognitive decline based on Montreal Cognitive Assessment (MoCA) scores. Among 47,165 participants, diclofenac and naproxen use were associated with a lower prevalence of dementia and AD compared with matched non-users, whereas etodolac showed no significant associations. Diclofenac users demonstrated reduced odds of dementia and AD. Naproxen showed similar cross-sectional associations. In longitudinal modeling, diclofenac users had a significantly slower rate of cognitive decline than non-users. These findings suggest a compound-specific association between NSAID use and AD, with diclofenac potentially modulating disease progression through anti-inflammatory mechanisms. The observed modulation of longitudinal cognitive decline supports further investigation of inflammatory pathways, including microglial and inflammasome signaling, as therapeutic targets in biomarker-defined AD populations.\n\nID: 42427876\nTitle: Grey matter degeneration during multiple sclerosis is linked to activation of neuronal necroptosis by oxidized phosphatidylcholines.\nAbstract: Oxidized phosphatidylcholines (OxPCs) are biomarkers of oxidative stress found in grey matter (GM) lesions during multiple sclerosis (MS), yet their distinct role in GM neurodegeneration remains undefined. Here we report that stereotaxic OxPC deposition in the mouse spinal cord GM induces age dependent neuroinflammation and neurodegeneration. Microglia are the predominant macrophages responding to OxPC induced GM lesions and help to mitigate acute neurodegeneration. Neuronal necroptosis activation in mouse GM lesions and neuronal upregulation of OxPCs and necroptosis activation in MS GM lesions suggest OxPC induced necroptosis promote GM degeneration during MS. In support, necroptosis inhibition ameliorates OxPC induced GM neuron loss. Finally, iron(ii)-containing heme deposition in the GM induces both OxPC formation and neuronal necroptosis activation, suggesting an endogenous upstream mechanism for generating neurotoxic OxPCs. These results highlight a plausible link between heme deposition, lipid peroxidation, and neuronal loss, and that necroptosis inhibition could help prevent GM neurodegeneration during MS.\n\nID: 42427832\nTitle: First worldwide multicenter validation of the POLARIS preclinical polarizer across biological models and imaging paradigms.\nAbstract: Hyperpolarized ¹³C Magnetic Resonance Imaging (HP-MRI) enables real-time, non-invasive assessment of metabolism in diseases including cancer and neurodegeneration. Broader adoption has been limited by the complexity, duration, and lack of standardization of current hyperpolarization methods. This study evaluated POLARIS Preclinical, a parahydrogen-induced polarization (PHIP) hyperpolarizer designed to streamline production of hyperpolarized ¹³C agents. Four POLARIS systems were deployed across eight international research centers to produce hyperpolarized [1-¹³C]pyruvate doses within 90 seconds. In vitro and in vivo imaging was conducted in multiple animal models using MRI systems operating at 1.4, 3, 7, and 9.4 Tesla. Metabolic conversion of pyruvate to lactate and bicarbonate was successfully measured across all sites. POLARIS enabled rapid, reproducible production of hyperpolarized [1-¹³C]pyruvate and demonstrated consistent performance across instruments, institutions, and field strengths. These results support standardized, high-throughput metabolic MRI for multicenter studies and translational research in oncology, neurology, and cardiovascular disease.\n\nID: 42427758\nTitle: Exosomal Profiling Reveals Mechanisms of Hibernation-Associated Neuroprotection.\nAbstract: Glaucoma is a group of eye diseases that affects 4 million people in the US and is one of the leading causes of vision loss due to damage to the eye's optic nerve (ON) which is composed of axons from retinal ganglion cells (RGCs) that transmit visual information to the brain. Injury to the ON often triggers RGC death and subsequent loss of visual function. Despite its increasing prevalence worldwide, effective therapies for glaucoma remain elusive. Notably, the thirteen-lined ground squirrel (TLGS) exhibits intrinsic neuroprotection during hibernation; however, reproducing this protective state pharmacologically has proven challenging. To elucidate the metabolic mechanisms underlying this resilience, we conducted untargeted metabolomic analyses on TLGS retinas at 6 hours, 3 days, and 7 days following ON crush. Retinas from awake and hibernating animals were compared to identify temporal and state-dependent metabolic signatures. Distinct metabolomic profiles were observed in hibernating animals relative to their awake counterparts. Pathway analyses revealed coordinated regulation of amino acid, lipid, and purine metabolism that likely contributes to hibernation-induced resilience. Furthermore, our findings indicate that hibernating TLGS retinas increase exosome biogenesis, prompting in vitro validation using TLGS-derived exosomes, which demonstrated robust neuroprotective and anti-inflammatory effects. Proteomic and transcriptomic characterization of exosomal cargo identified conserved miRNAs, mRNAs, and proteins implicated in redox balance, cytoskeletal stabilization, and stress-response regulation. Collectively, these data support the hypothesis that metabolic reprogramming and exosome-mediated intercellular signaling underlie hibernation-associated neuroprotection. Modulating these pathways may provide a blueprint for novel therapeutic strategies to mitigate neurodegeneration and promote recovery following optic nerve injury.\n\nID: 42427742\nTitle: Selective knockout of PKA regulatory subunits reveal opposite catalytic and metabolic consequences with implications for Alzheimer's disease.\nAbstract: cAMP-dependent Protein Kinase A (PKA) is a master regulator of cell signaling involved in energy metabolism, synaptic plasticity, and stress response. Dysregulated PKA signaling is implicated in diseases including neurodegeneration and cancer. PKA catalytic activity is regulated by two nonredundant regulatory subunits, Type I (RIα/RIβ) and Type II (RIIα/RIIβ), whose divergent functions are not fully understood. We generated double-knockout (KO) cell lines of RIα/RIβ and RIIα/RIIβ subunits and performed multiplexed MS-based proteomic and phosphoproteomic profiling under basal and glucose-perturbed conditions. We found that RI and RII loss drives distinct, and often opposite, remodeling of the cellular proteome and phosphoproteome. While both mutants blunted metabolic flexibility to glycolytic stressors and stimuli, RI and RII KO cells exhibited elevated and depressed glycolytic signaling, respectively. Interestingly, RI KO increased the abundance and kinase activity of the PKA catalytic subunit Cα isoform, leading to an increase in PKA substrate phosphorylation, whereas RII KO decreased the abundance, kinase activity, and substrate phosphorylation by the catalytic subunit Cβ isoform. Notably, one of the most differentially affected PKA sites between RI and RII KOs maps to Tau, whose hyperphosphorylation is a hallmark of Alzheimer's disease. Loss of RI increased Tau phosphorylation, which was not only caused by increased PKA catalytic activity, but also a higher binding affinity of Tau to RII subunits on the negatively-charged flexible linker region. Overall, the present study demonstrates that PKA RI and RII subunits play nonredundant roles in modulating PKA activity, metabolic flexibility, and phospho-regulation of key disease-associated substrates such as Tau.\n\nID: 42427719\nTitle: Neuroticism is linked to cognitive decline and increased risk of Alzheimer's disease through dysregulation of excitatory neurons.\nAbstract: Neuroticism is an established risk factor for Alzheimer's disease (AD), yet the molecular mechanisms linking this personality trait to neurodegeneration remain poorly understood. We leveraged single-nucleus RNA-sequencing data from longitudinal cohort studies of cognitive aging (n = 655) to investigate the mechanisms mediating the association between neuroticism and AD. We identified two genes associated with neuroticism, both of which are downregulated in excitatory neurons: ADRA1B and LY6E-DT . In addition, we found that neuroticism is associated with enrichment of a specific excitatory neuron subpopulation: Exc.12. Further analysis revealed that Exc.12 partially mediates the relationship between neuroticism and AD, accounting for 12.2% of the total effect. The dysregulation of excitatory neurons may represent a key cellular change that links neuroticism to AD.\n\nID: 42427633\nTitle: Synaptic activity controls local exposure of an 'eat-me' signal via ANO3-ITPR1 signaling.\nAbstract: Neuronal synapses are eliminated during brain development and disease through pruning by glial cells. Individual synapses are marked for engulfment by 'eat-me' signals, which include externalized phosphatidylserine. In apoptotic cells, phosphatidylserine externalization is driven by caspase-dependent activation of Xkr scramblases 1 and inactivation of specific flippases 2 . Localized caspase activation at neuronal synapses can mediate spatially-restricted synaptic phosphatidylserine exposure leading to synapse pruning by glial cells during development and neurodegeneration 3-6 . It is unknown which caspase-regulated flippases and scramblases promote synaptic phosphatidylserine exposure and whether there are any caspase-independent mechanisms of phosphatidylserine exposure relevant for synapse elimination. To address this question, we here develop a scalable CRISPR screening approach, COMPASS-seq (compartment-anchored sgRNA screen sequencing), to uncover the genetic underpinnings of subcellular phenotypes. COMPASS-seq is compatible with in vitro and in vivo systems and a wide range of subcellular compartments; we here apply it to the neuronal synapse. We discover that inhibition of the caspase-independent, calcium-activated anoctamin ANO3 (TMEM16C) is sufficient to increase synapse numbers in vivo . ANO3 co-localizes with IP3 receptor 1 (ITPR1), a calcium channel in the endoplasmic reticulum, to form a postsynaptic signaling platform that drives spatially restricted phosphatidylserine exposure at synapses. Activation of the ITPR1 calcium channel activity is sufficient to drive synaptic phosphatidylserine exposure via an ANO3-dependent but caspase-independent mechanism. Our results suggest a mechanism for integrating synaptic activity information to control synaptic pruning. The role of ANO3 in regulating synapses could shed light on the mechanisms underlying its numerous associations with both dementia 7 and other neurological diseases 8,9 .\n\nID: 42427630\nTitle: Shared and disease-specific human brain vascular signatures in Alzheimer's disease, frontotemporal dementia, and Huntington's disease.\nAbstract: The blood-brain barrier (BBB) plays a central role in brain function and is increasingly implicated in neurodegenerative disease. Major neurodegenerative disorders, including Alzheimer's disease (AD), frontotemporal dementia (FTD), and Huntington's disease (HD), share overlapping pathological features. Yet, the extent to which these diseases converge or diverge at the level of BBB-associated cell types remains poorly understood. Here, we performed a comparative analysis of vessel-enriched human brain transcriptomic datasets across AD, FTD, and HD to define shared and disease-specific neurovascular alterations. We identify a partially conserved transcriptional signature of vascular dysfunction across all three diseases, alongside disease-specific changes in endothelial, pericyte, and perivascular cell populations. Endothelial remodeling was most prominent in capillary and venous segments, highlighting segment-specific vulnerability along the arteriovenous axis. Notably, we identified two molecularly distinct human pericyte subtypes across all three datasets and found a consistent reduction in the matrix-type pericytes (M-peri) fraction, suggesting a selective decline. Cell-cell communication analysis further revealed reorganized endothelial-pericyte signaling networks, with prominent alterations in extracellular matrix-associated pathways, including LAMININ, COLLAGEN, FN1, and NCAM, together with changes in contact-dependent and vascular signaling pathways such as NOTCH and VEGF. Together, our findings define shared and disease-specific neurovascular mechanisms across major neurodegenerative disorders and highlight BBB-associated pathways as central features of neurodegeneration, providing a framework for future diagnostic and therapeutic strategies.\n\nID: 42427570\nTitle: A 3D Human Neuron-on-Chip Platform to Monitor Neuronal Injury Responses.\nAbstract: Traumatic brain injury (TBI) is a major cause of neurological dysfunction and long-term neurodegeneration, yet the intrinsic neuronal contributions to TBI pathophysiology remain incompletely defined. Here, we present a novel Neuron-on-Chip microfluidic platform that can be used to mechanically injure mature human prefrontal cortex neurons (hPFCs) embedded in three-dimensional (3D) hydrogels, enabling the study of injury responses in pure neuronal cultures. We assessed real-time calcium dynamics across 13 metrics of single-cell and network activity, revealing a biphasic injury response: an early phase (0.5-24 hr) characterized by excitotoxicity, hyper-synchronized bursting, and network collapse; and a late phase (8 d) marked by sustained depolarization and structural remodeling. Secretome profiling uncovered progressive elevations in extracellular pT181 and total Tau from days 1 to 5 post-injury. Cytokine analyses identified early (24 hr) elevations in IP-10, IL-10, IFNα2, and NCAM, and late increases (8 d) in CXCL9 and MPO, linking neuronal activity changes to stage-specific inflammatory signaling. Immunocytochemistry and immunoblotting confirmed temporally ordered upregulation of calpain-1 and active caspase-3 (days 1-3), phosphorylated Tau (AT8+, days 5-8), and neurofibrillary tangle-like Tau aggregates (NFT+, day 8). These findings establish our platform as a scalable microphysiological model for probing the dynamic cellular and molecular sequelae of neuronal response to injury, offering insights into neurodegeneration and opportunities for therapeutic discovery.\n\nID: 42427540\nTitle: An optimized \"hypoxia in a pill\" regimen reverses neurodegenerative disease phenotypes in multiple preclinical models.\nAbstract: A growing body of pre-clinical research has demonstrated the therapeutic potential of chronic, continuous hypoxia (11% FIO2) for treating both rare and common forms of neurodegeneration (1). However, the chronic delivery of hypoxic gas poses both practical challenges and long-term safety concerns. We previously introduced a small molecule, \"hypoxia-in-a-pill\" regimen that combines the hemoglobin affinity enhancer (GBT440) -- which limits oxygen delivery to tissues -- with a HIF-2α inhibitor (PT2399) to prevent compensatory erythropoiesis that can be detrimental. While this regimen extended the lifespan of the Ndufs4 KO mouse model of Leigh syndrome, its efficacy still did not match that of chronic 11% FIO2. Here we report an optimized combination that now utilizes GBT601, a second-generation hemoglobin affinity enhancer with longer half-life and greater hemoglobin occupancy, again with PT2399. Here we report that the GBT601/PT2399 combination achieved therapeutic hypoxia and demonstrated strong efficacy comparable to continuous breathing of 11% FIO2 by halting neurodegeneration and even reversing neurological symptoms in three different mouse models: Leigh syndrome, Friedreich's ataxia, and Parkinson's disease. The dual targeting regimen led to a striking extension in median lifespan in the Leigh syndrome model, from a median of ∼62 day to 158 days, when initiated after onset of advanced disease. Importantly, body weight was stable with the combination and it did not induce any signs of pulmonary hypertension, likely due to attenuation of HIF-2α. Our findings motivate additional pre-clinical and even clinical studies to evaluate the safety and efficacy of the GBT601/PT2399 combination.\n\nID: 42427539\nTitle: Loss of the lncRNA SOX1-OT promotes p53-dependent cell-cycle arrest in astrocytes.\nAbstract: Long non-coding RNAs (lncRNAs) are increasingly recognized as regulators of brain cell function, but their roles in astrocyte biology and neurodegeneration remain poorly understood. Here, we identify Sox1ot/SOX1-OT as a conserved, brain-enriched lncRNA that is downregulated in Alzheimer's disease and in reactive astrocyte states. Antisense oligonucleotide-mediated depletion of Sox1ot in astrocytes revealed a transcriptional program marked by activation of p53 target genes selectively associated with cell-cycle inhibitory pathways. Consistent with this, Sox1ot depletion enhanced p53 occupancy at target promoters such as Cdkn1a , increased Cdkn1a expression and levels of its protein product p21, and thereby induced G1 arrest and reduced astrocyte proliferation. In contrast, other canonical p53 outputs, including apoptosis and senescence, were not affected, indicating that Sox1ot selectively modulates distinct branches of p53 signaling. Notably, loss of Sox1ot/SOX1-OT was accompanied by impaired glutamate uptake, reduced lactate secretion, and altered astrocyte support functions, suggesting that these deficits arise as downstream consequences of the p53-dependent transcriptional shift rather than direct primary effects of Sox1ot loss. Together, these findings identify SOX1-OT as an astrocyte-enriched regulatory layer that constrains a p53-dependent cell-cycle program and highlight its role in shaping astrocyte state transitions in Alzheimer's disease.\n\nID: 42427519\nTitle: Humanized tauopathy chimeras uncover microglial and lncRNA strategies for neuroprotection.\nAbstract: Human genetics implicates innate immunity as a key modifier of tau toxicity, yet human-specific neuroimmune mechanisms remain difficult to test in vivo. Here, we developed HuMiNAX, the first humanized iPSC-based neuroimmune xenograft model of tau-associated neurodegeneration, enabling human microglia to interact with human neurons and astrocytes in the adult mouse brain. In HuMiNAX, tau seeding induced aggregation only in mutation-carrying human neural grafts, causing neuron loss and inflammatory activation of human microglia. Progranulin-overexpressing human microglia dampened tau-associated inflammation, preserved neurons, and restored neuronal gene-expression and RNA-splicing programs, supporting microglial control of neuronal resilience. CRISPRi knockdown of the human-specific lncRNA HNRNPK-AS1 also protected neurons in HuMiNAX. These findings establish HuMiNAX as a human neuroimmune model of tauopathy and identify microglial and RNA-mediated strategies of neuronal resilience.\n\nID: 42427320\nTitle: Frontotemporal Lobar Degeneration-TDP Type C With Striatal Glial Cytoplasmic Inclusions and Motor Neuron Degeneration.\nAbstract: We report an autopsy case of frontotemporal lobar degeneration (FTLD)-TDP type C with severe striatal involvement and annexin A11- and phosphorylated TDP-43-positive glial cytoplasmic inclusions. The patient developed progressive asymmetric rigidity accompanied by marked striatal atrophy and showed both upper and lower motor neuron involvement. These findings expand the clinicopathological spectrum of FTLD-TDP type C and may support the concept of an annexin A11-associated pathogenic continuum linking FTLD and amyotrophic lateral sclerosis.\n\nID: 42427054\nTitle: Youthful-state extracellular vesicles for targeted therapy of intervertebral disc degeneration: resolving inflammation and pyroptosis through NF-κB suppression and NLRP1 inactivation.\nAbstract: Intervertebral disc degeneration pathogenesis involves chronic inflammation and cell death, highlighting the need for targeted therapeutic strategies. Extracellular vesicles (EVs) have emerged as promising bioactive materials for designing therapeutic approach. In this study, we demonstrate that youthful-state EVs (Y-EVs) outperform aged donor-derived EVs (O-EVs) in resolving inflammatory cascades within nucleus pulposus (NP) cells. EVs from young rats significantly suppressed TNF-α-induced inflammation in NP cells by reducing pro-inflammatory cytokine secretion, inhibiting extracellular matrix catabolism, and ameliorating rat disc degenerationin vivo. Mechanistically, CD55 enrichment in Y-EVs attenuated NF-κB pathway activation, thereby disrupting inflammatory transcriptional programs. CD55 knockdown abrogated the anti-inflammatory efficacy of Y-EV, confirming its functional necessity. Besides, we identified thioredoxin (TRX) as a critical suppressor of NLRP1 inflammasome activation via direct protein binding, which inhibited NP cell pyroptosis. Crucially, CD55 in Y-EVs facilitated TRX-mediated NLRP1 suppression, whereas O-EVs failed to upregulate TRX or suppress the NLRP1 inflammasome. This study highlights the age-dependent functional divergence of EV bioactivity and establishes CD55 as a key determinant of their therapeutic superiority. The TRX-NLRP1 interaction represents a novel target for disc degeneration intervention, positioning youthful-state EVs as an optimized bioactive material for disc regeneration strategies.\n\nID: 42426931\nTitle: Transcriptomic Evidence of Mitochondrial Double-Stranded RNA Accumulation in Brain Aging and Alzheimer's Disease.\nAbstract: Mitochondria and inflammation are tightly linked in aging and Alzheimer's disease (AD), and recent evidence implicates mitochondrial double-stranded RNA (mt-dsRNA) as a potential trigger of inflammation. We examined mt-dsRNA accumulation and dsRNA signaling in brain aging and AD using complementary human brain tissue and in vitro transcriptomic datasets by quantifying mitochondrial transcripts, dsRNA editing, and related gene expression patterns. We found that mt-dsRNA signatures increased after midlife and coincided with reduced expression of mitochondrial RNA processing and translation machinery, along with increased expression of dsRNA antiviral signaling proteins, consistent with cytoplasmic mt-dsRNA-driven inflammation. In AD brains, mt-dsRNA signatures were further increased and correlated with cognitive impairment, neuropathological severity, and AD risk genotypes. Genes associated with these measures reflected altered ubiquitin-dependent regulation of antiviral signaling, potentially indicating altered sensitivity to mt-dsRNA. Together, these findings highlight mitochondrial RNA homeostasis as an unrecognized contributor to age- and AD-related neurodegeneration and identify mt-dsRNA as a potential driver of chronic inflammation in the brain.\n\nID: 42426923\nTitle: Protein kinase CK2α' as a dual modulator of neuroimmune signaling and synaptic dysfunction in tauopathy.\nAbstract: Tauopathies are a group of neurodegenerative diseases characterized by tau accumulation, neuroinflammation, and synaptic dysfunction, yet effective treatments remain elusive. Protein kinase CK2 is a holoenzyme composed of two regulatory (CK2β) and two catalytic subunits (CK2α and CK2α') and has been linked to multiple aspects of tau pathology. However, genetic evidence defining the specific contributions of CK2 subunits to tau phosphorylation and tauopathy remains lacking. Elucidating subunit-specific roles is critical for the rational development of CK2-targeted therapies. To investigate the impact of CK2 in tauopathy, Neuro-2a and primary cell cultures expressing mutant tau were treated with siRNAs targeting the two catalytic subunits of CK2, CK2α and CK2α'. In addition, the PS19 mouse model of tauopathy was bred to be haploinsufficient for the catalytic subunit CK2α'. Changes in pathology and symptomatology were analyzed via immunohistochemistry, immunoblotting, RNA-sequencing, in situ hybridization, electrophysiology, and Barnes Maze. We found that the expression of the catalytic subunit CK2α', but not catalytic CK2α or regulatory CK2β subunits, was elevated in postmortem brains of dementia patients and in the hippocampus of PS19 tauopathy mice, especially in neurons and microglia. Using a haploinsufficient model of CK2α' in PS19 mice, we demonstrated that the PS19:CK2α'(+/-) mice had significantly decreased phosphorylated tau and total tau burden in the hippocampus and cortex. CK2α' depletion also attenuated microglial activation, pro-inflammatory cytokine production and microglia synaptic engulfment, and enhanced synaptic gene expression, synaptic density, and long-term potentiation. Importantly, CK2α' haploinsufficiency rescued cognitive deficits assessed in the Barnes maze. Here, we show CK2α', one of the two catalytic subunits of CK2, as a novel regulator of tau-mediated neurodegeneration. These effects appear to be mediated through both neuronal and glial functions and may involve CK2α'-dependent modulation of tau phosphorylation as well as neuroinflammatory and immune signaling pathways. These findings identify CK2α' as a mechanistically defined and potentially druggable target for therapeutic strategies aimed at modifying tau-driven neurodegeneration.\n\nID: 42426471\nTitle: Cutaneous silent period in patients with obstructive sleep apnea.\nAbstract: Empirical evidence suggests that the duration of the Cutaneous Silent Period (CuSP) is significantly extended in pathological states such as Idiopathic Parkinson's Disease (IPD), Restless Legs Syndrome (RLS), and dystonia, all of which are correlated with the degeneration of dopaminergic neurons. This neurodegenerative process is a critical factor in the etiology of Obstructive Sleep Apnea (OSA). In light of this active participation, the present study sought to assess the CuSP in patients with OSA. A cohort comprising forty individuals diagnosed with OSA and forty healthy controls, all of whom underwent polysomnographic assessments, was incorporated into this investigation. The study meticulously analyzed the onset time, termination time, and duration of the CuSP in both median nerves utilizing electromyographic techniques. In the study examining the median nerve CuSP study, right and left CuSP was significantly prolonged in patients with OSA (p = 0.001, p < 0.001). Additionally, the onset time of the right and left CuSP was found to be shorter in the patient group (p = 0.017, p = 0.003). The findings indicate that the duration of the CuSP is significantly prolonged in patients with OSA, similar to observations in IPD, RLS and dystonia. These results highlight the potential clinical relevance of CuSP duration as a biomarker for OSA-related neuronal alterations.\n\nID: 42426383\nTitle: Immune Activation and Glial Dysfunction in Spinocerebellar Ataxias: From Cerebellar Landscape to Disease-Driven Mechanisms and Immunomodulation.\nAbstract: Spinocerebellar ataxias (SCAs) comprise a clinically and genetically heterogeneous group of autosomal dominant neurodegenerative disorders. Despite the recognized role of specialized cerebellar glia in cerebellar development and dysfunction, immune activation and non-immune glial responses remain understudied in SCAs. This narrative review compiles evidence from cellular, animal, and human models on the cerebellar immune landscape and the specific pathways that drive homeostatic failure and neuroinflammatory cascades across SCA subtypes. Microgliosis emerges consistently-and often early- as a generalized feature across the SCA spectrum, preceding neurodegeneration in several subtypes. Concurrently, reactive astrogliosis extends broadly, reflecting widespread macroglial surveillance and metabolic stress regulation throughout histologically preserved gray matter, with specialized homeostatic failure of Bergmann glia in SCA1, SCA2, and SCA7. Peripheral inflammation, manifests as early as the prodromal stage and correlates with the cognitive-affective deficits in SCA2 and associates with the mutation size in SCA3, positioning it as integral to pathogenesis rather than epiphenomenal. Diverse, partially shared signaling pathways converge on multi-lineage glial breakdown and reciprocal neuroimmune crosstalk. These mechanisms involve NF-κB (SCA1,3,17), cGAS-STING (SCA2), TLR/MyD88 (SCA6), and JNK/c-Jun (SCA1,2,7). This review establishes abnormal reciprocal immune/non-immune glia crosstalk as a core pathogenic principle across SCAs, revealing novel therapeutic opportunities. In fact, targeting convergent signaling nodes such as NF-κB, or JNK pathways, holds disease-modifying potential across multiple subtypes. Future research should prioritize standardized comparative studies, longitudinal analyses linking both inflammation and non-immune glial pathology to clinical progression, and clinical trials evaluating targeted immunomodulatory and glial homeostatic-supportive agents.\n\nID: 42426293\nTitle: Glial Cysteine Cathepsins: From Homeostasis to Neurodegeneration.\nAbstract: Glial cells, namely microglia, astrocytes, and oligodendrocytes, play crucial roles in maintaining homeostasis in the central nervous system and orchestrating responses to injury, infection, and disease. Among the molecular regulators of glial function, cysteine cathepsins have emerged as key modulators of both physiological and pathological processes. These lysosomal peptidases are traditionally known for their housekeeping roles in protein degradation; however, accumulating evidence highlights their broader involvement in antigen presentation, microglial and astrocyte reactivity, inflammatory signalling, apoptosis, and myelination. Under normal conditions, cysteine cathepsins support essential functions in the central nervous system, including immune surveillance and tissue remodelling. Conversely, their dysregulation, characterized by overexpression, increased enzymatic activity, or mislocalization, can promote neuroinflammation and neurodegeneration, contributing to the pathogenesis of disorders such as Alzheimer's disease and multiple sclerosis. This review provides a comprehensive synthesis specifically focused on the diverse roles of cysteine cathepsins across major glial cell types, systematically summarizing current knowledge in microglia, astrocytes, and oligodendrocytes. We emphasize their cell type-specific, context-dependent, protective, and deleterious functions. Furthermore, we discuss mechanistic links between cysteine cathepsin activity and neurodegenerative processes and evaluate the therapeutic potential and current limitations of selectively targeting glial cysteine cathepsins. A deeper understanding of the context-dependent dual roles of these enzymes in brain physiology and pathology is critical for designing targeted interventions that could mitigate neuroinflammation and neurodegeneration.\n\nID: 42426288\nTitle: The emerging role of circular RNAs in neurodegenerative diseases and viral infections.\nAbstract: Circular RNAs (circRNAs) represent a class of highly stable, covalently closed RNA molecules increasingly recognized as important regulators of brain aging and neurodegenerative disease. Growing evidence also implies circRNAs in viral infection, suggesting a potential intersection between viral neuropathogenesis and neurodegeneration. However, no studies have yet directly integrated circRNAs, neurotropic viral infections, and neurodegenerative disorders within a single mechanistic framework. To date, specific circRNAs have been linked to the progression of Alzheimer's disease and Parkinson's disease, where they regulate central pathological processes including amyloid-β clearance, neuroinflammation, synaptic plasticity, neuronal apoptosis, and oxidative stress. Moreover, it has been established that both host cells and viruses produce circRNAs during infection. Virus-derived circRNAs can enhance viral replication, promote immune evasion, and support latency. In contrast, host circRNAs contribute to antiviral defense by acting as microRNA sponges, interacting with viral proteins, or encoding peptides with antiviral activity, mechanisms particularly explored in viral oncogenesis. In this review, we will evaluate the most updated research evidence on the role of circRNAs in major neurodegenerative diseases and neurotropic viral infections. Considering the growing concern regarding the long-term neurological consequences of viral infections, including chronic neuroinflammation, viral reactivation, and post-viral syndromes, dysregulated circRNAs may represent a mechanistic link between viral infection and associated neurodegenerative processes. Finally, we will discuss future directions for identifying circRNAs-based biomarkers and developing circRNAs-targeted therapeutic strategies for age-related and virus-associated neurological disorders.\n\nID: 42426148\nTitle: Multitarget therapeutic potential of sulforaphane in ethidium bromide-induced neurotoxicity in multiple sclerosis-like pathology: comparison with omaveloxolone and dimethyl fumarate on neuroprotection and systemic recovery.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by demyelination, neuroinflammation, and neurodegeneration. This study investigates the neuroprotective potential of Sulforaphane (SFN) in ameliorating ethidium bromide (EBRM)-induced MS-like pathology in Wistar rats. The efficacy of SFN at two doses (SFN1.5 and SFN3) was compared to FDA-approved Nrf2 activator drugs, omaveloxolone (OMV15) and dimethyl fumarate (DIMF50). EBRM administration caused neurobehavioral deficits, demyelination, oxidative stress, axonal degeneration, and inflammation. It disrupted key cellular pathways, including Nrf2/HO-1/SIRT-1, JAK/STAT-3/mTOR, and BACE-1/Gamma-secretase/MAPT, as well as caused neurotransmitter imbalances. SFN3 demonstrated significant improvement in motor function, cognitive performance, neurotransmitter levels antioxidant enzymes and alleviated neuroinflammation by modulating inflammatory cytokines. Molecular analyses showed that SFN3 increased Nrf2/HO-1/SIRT-1 levels while decreased pro-inflammatory and neurodegenerative markers such as STAT-3, mTOR, and BACE-1 levels. Gross pathological, Histopathological, and LFB studies indicated reduced demyelination and liver damage. SFN3 also demonstrated favourable systemic safety compared to OMV15. While DIMF50 showed the highest overall efficacy, SFN3 showed consistent modulation of pathological markers, neuroprotective effects, and safety profile. These findings suggest that SFN3 may have therapeutic potential for further translational research in MS. Future studies should validate its clinical relevance and explore combinatorial therapies with existing MS treatments to enhance therapeutic outcomes.\n\nID: 42430091\nTitle: The Role of PGC-1α in Neurodegenerative Diseases: Molecular Mechanisms, Translational Challenges, and Therapeutic Potential.\nAbstract: Neurodegenerative diseases (NDDs) are progressive disorders in which mitochondrial dysfunction, oxidative stress, proteostasis failure, neuroinflammation, and synaptic damage progressively interact to drive neuronal vulnerability. Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) links metabolic adaptation to stress-response pathways that are repeatedly disrupted in Alzheimer's disease, Parkinson's disease, Huntington's disease, polyglutamine (PolyQ) disorders, and amyotrophic lateral sclerosis. Rather than providing only an updated catalogue of studies, this review organizes the evidence into a cross-disease rheostat framework that explains why PGC-1α modulation is protective in some settings but incomplete or maladaptive in others. Current findings indicate that PGC-1α supports mitochondrial biogenesis, oxidative phosphorylation, antioxidant defense, mitophagy, autophagy, protein quality control, and inflammatory balance. However, its effects are highly context dependent. In several models, restoration of PGC-1α-related signaling improves mitochondrial function and reduces neuronal injury, whereas broad, sustained, or cell-inappropriate activation may produce limited benefit or undesirable outcomes. These observations suggest that PGC-1α is not a simple neuroprotective switch, but a flexible regulatory hub whose therapeutic value depends on cell type, isoform profile, disease stage, and activation level. Emerging strategies, including small-molecule modulators, gene delivery, antisense-based approaches, nanoparticle systems, and exercise-related interventions, remain largely preclinical and face major barriers related to CNS delivery, pathway selectivity, dose and cell-type control, peripheral safety, and validated target-engagement biomarkers. Nevertheless, clinical translation requires stronger causal validation, reliable target-engagement biomarkers, selective delivery methods, and long-term safety assessment. Future research should focus on precision-based modulation of PGC-1α to determine when and how this pathway can be safely used for disease modification. Such a careful approach may help transform PGC-1α from a broad experimental target into a clinically relevant strategy for well-defined neurodegenerative phenotypes.\n\nID: 42427517\nTitle: AART enables fast and accurate cross-platform proteomic translation.\nAbstract: Plasma proteomic profiling has been widely used for biomarker discovery, disease prediction and diagnosis, and patient stratification. However, technical differences across assay platforms often result in low-to-moderate agreement, limiting study reproducibility, data integration, and model transferability. Here we present AART, a cross-platform proteomic translation framework that integrates matched-protein ridge regression with proteome-wide residual learning. We benchmarked AART spanning three independent cohorts profiled using three major platforms, including Olink, SomaScan, and mass spectrometry. Across all six translation directions, AART achieved the best performance compared with baseline methods for both overlapping and non-overlapping protein translations, with a relative improvement of 92.0% on average over direct mapping and by up to 31.6% over cpiVAE, the strongest baseline. Proteins that were accurately translated and improved by AART were enriched for extracellular, vesicle-associated, and tissue-restricted plasma biology. In downstream applications, AART improved the reproducibility of proteomic association analyses relative to direct cross-platform comparison by 75.5% for type 2 diabetes and 370.6% for Alzheimer's disease. AART-enabled cohort integration enhanced diagnostic accuracy for amyotrophic lateral sclerosis by 92.6% compared with non-integration analysis. AART was overall one to three orders of magnitude faster than cpiVAE, facilitating biobank-scale applications. Together, these results establish AART as a fast, accurate, and scalable framework for cross-platform proteomic translation, enabling more reproducible, transferable, and integrated proteomic research.\n\nID: 42424231\nTitle: Neurofilament Light Chain as a Biomarker in Neurology.\nAbstract: Neurofilament light chain (NfL) has emerged as a highly sensitive biomarker of neuroaxonal injury across diverse neurological disorders. This review synthesizes current evidence regarding its diagnostic, prognostic, and therapeutic-monitoring utility, while outlining major clinical limitations and emphasizing the complementary role of glial fibrillary acidic protein (GFAP). NfL concentrations increase following axonal damage and correlate with inflammatory activity, lesion burden, and long-term disability progression in multiple sclerosis. Elevated levels also reflect neurodegeneration in Alzheimer's disease, predict disease severity and survival in amyotrophic lateral sclerosis, and are associated with motor and cognitive decline in Parkinson's disease and multiple system atrophy. In acute neurological conditions, including traumatic brain injury and stroke, NfL serves as a robust indicator of the extent of neuronal injury. Interpretation is constrained, however, by substantial physiological variability related to age, renal function, body mass index, and comorbidities, limiting the utility of absolute cut-off values. GFAP provides complementary information by capturing astrocytic damage, and the GFAP/NfL ratio may aid in differentiating multiple sclerosis from neuromyelitis optica spectrum disorder. Integration of NfL with multimodal biomarkers- such as GFAP, tau proteins, proteomic and metabolomic signatures, and advanced neuroimaging-may enhance diagnostic specificity and prognostic accuracy. Future research priorities include establishing age-adjusted reference intervals, validating longitudinal thresholds, and incorporating NfL into therapeutic monitoring frameworks. Advances in these areas are expected to improve diagnostic precision and support broader clinical implementation of NfL.\n\nID: 42423631\nTitle: Identifying Gastrostomy Care and Home Gastrostomy Tube Feeding-Related Educational Content for Patients With Amyotrophic Lateral Sclerosis and Their Family Caregivers: A Delphi Panel With Professional Stakeholders.\nAbstract: Enteral nutrition is delivered through a gastrostomy tube to provide nutritional support to patients with amyotrophic lateral sclerosis (ALS) who have developed severe dysphagia at home. Complications may arise from gastrostomy and enteral nutrition when family caregivers do not provide adequate care. This study identifies key areas of educational content that can improve the care of patients with ALS requiring gastrostomy and home enteral nutrition. We conducted a modified three-round e-Delphi survey with health care experts to clarify their perspectives on the educational content regarding gastrostomy and home enteral nutrition disseminated among patients with ALS and their family caregivers. The experts provided their opinions on specific educational content areas, and their responses were analyzed to identify areas of consensus and divergence. Accordingly, in Rounds 1-3 of the survey, 16 experts, including registered nurses (n = 6), advanced practice registered nurses (n = 3), clinical neurologists (n = 3), and dieticians (n = 4), participated. In Round 3, four categories and 39 educational components reached consensus. The results provide a framework for developing educational nursing interventions for family caregivers of patients with ALS receiving home enteral nutrition through gastrostomy tubes and for defining the essential elements of the educational content of such interventions.\n\nID: 42414949\nTitle: Biological sex differences in neurodegenerative diseases in Africa: a scoping review of evidence and research gaps.\nAbstract: Biological sex is a well-established determinant of risk, progression, and therapeutic response in neurodegenerative diseases (NDs). However, current evidence on sex differences in NDs is from high-income Western populations. This review aims to map and synthesize evidence on biological sex differences in NDs in Africa, and to identify key research gaps. This scoping review was conducted in accordance with the Joanna Briggs Institute methodology and reported in accordance with the PRISMA-ScR guidelines. A literature search was conducted on PubMed, African Journals Online, Sabinet Journals, ScienceDirect, and Google Scholar. We included studies conducted in African countries that reported sex disaggregated data or examined biological sex differences in at least one ND. Data were synthesized descriptively. All included studies reported sex distribution, but most (about 84%) did so only descriptively. Approximately 17% conducted sex-stratified analyses beyond prevalence. Similar to global epidemiological trends, several studies suggested a higher prevalence or odds of dementia and multiple sclerosis among females, while male predominance was observed in Parkinson's disease and Amyotrophic lateral sclerosis studies. An earlier onset and a higher mutation frequency in LRRK2-G2019S were reported in females with Parkinson's disease in some studies, while another study reported a higher mortality rate in females with dementia. No study evaluated sex specific biomarker profiles, disease progression, or treatment response. Evidence on biological sex differences in NDs in Africa remains limited and is largely descriptive. Mechanistic, longitudinal, and biomarker-based investigations are largely absent.\n\nID: 42405014\nTitle: Cholesterol in amyotrophic lateral sclerosis: a bystander, a biomarker, or a target?\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron loss. In addition to the different pathogenic mechanisms, in recent years, increasing attention has been directed toward the role of lipid metabolism in ALS pathogenesis, although the clinical relevance of lipid alterations in ALS may differ from their well-established role in cardiovascular disease. This review critically examines the multifactorial relationship between cholesterol and ALS through three perspectives: (1) as a risk factor for disease onset, (2) as a prognostic biomarker of disease progression, and (3) as a potential therapeutic target. Epidemiological and genetic studies suggest a complex and sometimes contradictory association between lipid profile and ALS risk. Elevated LDL-cholesterol and total cholesterol have been linked to increased disease susceptibility in some cohorts, with Mendelian randomization studies supporting a potential causal role. Conversely, evidence regarding HDL-cholesterol remains conflicting and may be influenced by sex-specific and metabolic factors. As a prognostic biomarker, hyperlipidemia has been variably associated with prolonged survival in ALS patients; however, these findings often lose significance after adjusting for body mass index and nutritional status, suggesting that lipid levels may reflect systemic metabolic reserve rather than directly modulating disease progression. Pharmacological modulation of cholesterol reveals further complexity. While statins are generally not associated with increased ALS risk in clinical studies, preclinical models show divergent effects: some statins accelerate disease progression, while others like lovastatin may be protective. Other lipid-lowering drugs, including fibrates and PCSK9 inhibitors, may also influence ALS-related pathways beyond cholesterol lowering, although their potential role remains to be clarified.\n\nID: 42404435\nTitle: Value of synaptic proteins as biomarkers in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a heterogeneous and rapidly progressing neurodegenerative disorder with limited treatment options. Therefore, there is a critical need for biomarkers that capture the diverse pathophysiological mechanisms underlying disease onset and progression. Emerging evidence suggests that synaptic dysfunction is an early disease mechanism in amyotrophic lateral sclerosis. Using homebrew immunoassays, we explored a panel of pre- and post-synaptic proteins in cerebrospinal fluid of patients with amyotrophic lateral sclerosis (N = 57) and controls (N = 36). The potential value as a biomarker was explored by correlating cerebrospinal fluid levels with clinical parameters and established biomarkers for amyotrophic lateral sclerosis. Higher levels of Neurogranin (NRGN) (P = 0.003) and Vesicle-associated membrane protein 2 (VAMP2) (P = 0.014) were observed in patients with amyotrophic lateral sclerosis compared with controls. VAMP2, Synaptosome-associated protein 25 kDa (SNAP25) and β-synuclein (SNCB) correlated with individual relative disease stage, but none of the biomarkers correlated with disease progression rate. High levels of SNAP25 predicted worse survival in a univariate and stepwise multivariable analysis, but significance did not persist upon including Neurofilament light chain (NfL) levels. Synaptic proteins did not correlate with cerebrospinal fluid levels of neurofilaments or biomarkers of neuroinflammation, suggesting that they reflect different pathological mechanisms in amyotrophic lateral sclerosis. Our findings warrant further investigation to determine whether increased cerebrospinal fluid levels of synaptic proteins reflect synaptic breakdown or active release of synaptic proteins. This will help elucidate how synaptic dysfunction or damage contributes to elevated levels of synaptic markers in amyotrophic lateral sclerosis, and its underlying value as biomarker.\n\nID: 42404433\nTitle: Beyond motor neurons: peripheral TDP-43 pathology in skeletal muscle and intramuscular nerves in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a progressive neurodegenerative disease characterized by accumulation of the 43-kDa TAR DNA-binding protein (TDP-43). This neuropathological signature has been well documented within the CNS; however, recent findings indicate that the phosphorylated TDP-43 additionally deposits in peripheral tissues, including skeletal muscle and intramuscular nerves. These data warrant a change of view from a neurocentric perspective of amyotrophic lateral sclerosis pathogenesis towards a broader concept of TDP-43 proteinopathy extending both within and beyond the nervous system. In this review, we focus on current evidence supporting the presence of TDP-43 pathology in amyotrophic lateral sclerosis skeletal muscle, examining its topographic distribution, molecular characteristics and associations with intramuscular nerve bundles. We also discuss the susceptibility of intrinsic muscle cells, disrupted axonal transport and impairment in protein quality control. Phosphorylated TDP-43 pathology in muscle biopsies from amyotrophic lateral sclerosis patients has emerged as a promising tool in the early diagnosis of the disease. Moreover, we discuss the relevance of these findings to amyotrophic lateral sclerosis pathogenesis and potential therapeutic implications.\n\nID: 42404161\nTitle: Perspective and quality of life in amyotrophic lateral sclerosis patients undergoing percutaneous endoscopic gastrostomy.\nAbstract: Percutaneous endoscopic gastrostomy (PEG) is commonly used to manage dysphagia and nutritional failure, which are among the most frequent and severe complications of amyotrophic lateral sclerosis (ALS). While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p > 0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p > 0.001); 54.2% felt that PEG was cosmetically acceptable. Consistent positive rates were reported by caregivers. The GIQLI digestion subscale values significantly improved from baseline (28.3; SD = 6.6) to discharge (30.97, SD = 5.84) and were maintained at 1-month follow-up (30.21, SD = 6.7; p = 0.014). Conversely, in follow-up assessments, we observed a significant reduction in the SF-36 physical component summary (PCS) subscale (baseline = 33.3; 1-month follow-up = 28.61; p = 0.032), which was accompanied by a significant worsening in the GIQLI physical dimension subscale (baseline = 9.63; 1-month follow-up = 7.38; p = 0.044). This study provides preliminary evidence that ALS patients have a positive perspective on PEG positioning, which may also have a beneficial effect on HRQoL related to gastrointestinal function.\n\nID: 42399593\nTitle: Early and severe masticatory muscle involvement in SOD1-ALS: a case report with biomarker-clinical dissociation.\nAbstract: \n\nID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases. Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.\n\nID: 42399082\nTitle: Radiologically inserted gastrostomy in advanced amyotrophic lateral sclerosis: clinical outcomes.\nAbstract: To evaluate survival and clinical outcomes in patients with amyotrophic lateral sclerosis (ALS) undergoing radiologically inserted gastrostomy (RIG) and to describe outcomes in patients in whom gastrostomy was indicated but not performed. This retrospective observational cohort study included patients with ALS followed by a multidisciplinary palliative care team between 2018 and 2020. Patients were classified according to gastrostomy status (RIG vs no RIG). Clinical data, respiratory support, nutritional status and survival outcomes were collected from medical records. Survival was analysed from gastrostomy indication using Kaplan-Meier curves stratified by baseline non-invasive ventilation (NIV) use. Among 155 patients with ALS, RIG was indicated in 53 and performed in 45; eight patients died before the procedure. 65 patients did not undergo gastrostomy. Median survival after RIG was 14.7 months, compared with 8 months in non-RIG patients who died. Baseline NIV use was associated with longer survival. No major safety concerns were identified. RIG appears to be a safe and feasible option in advanced ALS. Multidisciplinary care with integrated palliative involvement may facilitate referral, optimise nutritional support and support shared decision-making aligned with patients' goals of care. Further prospective studies are needed to confirm benefits and identify intervention timing.\n\nID: 42396333\nTitle: The Target ALS Global Natural History Study: Cross-platform proteomics to accelerate biofluid biomarker and drug target discovery in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal, rapidly progressive neurodegenerative disease of motor neurons for which therapeutics are limited. Improved biomarkers are imperative to improve patient care and therapeutic development. Here, we employed 35-plex isobaric tandem mass tag labeling based on isobutyl-proline reporter group (TMTpro) to perform unbiased proteomic analysis of cerebrospinal fluid (CSF) and plasma from control (n= 28, n= 31) and sporadic ALS (sALS) (n= 39, n= 41), from the Target ALS Global Natural History Study (TALS GNHS). We identified 2,875 proteins in CSF and 1,118 proteins in plasma and identified known and novel differentially expressed proteins (DEPs) between controls and sALS, some of which were orthogonally validated using immunoassay. Comparison of TMTpro-MS and Olink proximity extension assay proteomics revealed common and non-overlapping differentially expressed proteins illustrating strengths unique to each platform. This initial cross-sectional proteomic study of biofluids from the TALS GNHS, with unrestricted availability of study results to the research community, highlights the potential of this resource as a potent platform for ALS biomarker discovery.\n\nID: 42394962\nTitle: Decremental responses following repetitive nerve stimulation in spinal and bulbar muscular atrophy.\nAbstract: The presence of decremental responses following repetitive nerve stimulation (RNS) in amyotrophic lateral sclerosis (ALS) is well established. However, in spinal and bulbar muscular atrophy (SBMA), a rare X-linked recessive lower motor neuron disease, the incidence and distribution of decremental responses across different muscles have not been thoroughly investigated. Patients with SBMA were retrospectively identified in our database. RNS at a frequency of 3 Hz was performed on five muscles: the abductor pollicis brevis (APB), abductor digiti minimi (ADM), upper trapezius, deltoid, and facial muscles (frontalis or nasalis). A total of forty patients were identified. A significant (> 5%) decremental response in at least one muscle was observed in all patients. It was observed more frequently in proximal muscles than in distal muscles: deltoid (86%), trapezius (70%), facial muscles (44%), APB (37%) and ADM (25%). The magnitude of the decremental response in the deltoid was significantly higher than that in the other muscles. Our results demonstrated that decremental responses were frequently observed in patients with SBMA, with a distribution pattern similar to that in ALS. The fact that the decremental responses are observed in SBMA having an extremely chronic course would be relevant for the pathophysiological mechanism of the decremental response. The RNS findings provide valuable insights into the pathological mechanisms of SBMA and may contribute to the development of future treatments.\n\nID: 42393765\nTitle: Phenotype-specific muscle proteomic profiling in titinopathies.\nAbstract: Titinopathies are complex neuromuscular disorders with multiple phenotypes. The gene's size, comprising 364 exons, as well as the protein's size of 3.8 MDa and its extensive network of protein interactors, are key factors underlying this complexity. Various phenotypes characterize titinopathies, and this study focuses on two of them: arthrogryposis and myofibrillar myopathies. The protein deregulations associated with these two phenotypes remain unknown or have been minimally explored; however, understanding these consequences is essential for better characterizing the pathophysiological aspects of these titinopathies.The objective was to analyze protein deregulations in two cohorts of French patients with titinopathies exhibiting the arthrogryposis and myofibrillar myopathy phenotypes, and to compare them with control individuals. Protein extracts were obtained from muscle biopsies of patients, and changes in protein levels within these two groups were analyzed by mass spectrometry. The results indicate specific deregulations in each group. The networks analyzed revealed deregulation of proteins involved in fibrosis mechanisms or in the actomyosin complex for the arthrogryposis phenotype. Regulation of the muscle contraction system through deregulation of proteins involved in the cytoskeleton is impacted in patients with myofibrillar myopathy. The proteins that are quantitatively abnormal in these two groups also provide insights into the major signaling networks disrupted in titinopathies. These findings will contribute to a more precise characterization of titinopathies, enabling the identification of phenotype-specific biomarkers and potentially guiding the search for targeted therapies for these neuromuscular disorders.\n\nID: 42385762\nTitle: Global, regional, and national burden of tuberculosis and multidrug-resistant tuberculosis by HIV status, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9·11 million (95% uncertainty interval 8·04-10·3) incident cases of all-form TB, 1·22 million (0·98-1·49) deaths, and 54·6 million (43·8-65·5) DALYs globally. HIV-related TB comprised 781 000 (690 000-879 000) incident cases and 210 000 (142 000-279 000) deaths, contributing 11·0 million (7·56-14·3) DALYs. MDR-TB accounted for 466 000 (198 000-1 080 000) incident cases, 102 000 (31 700-238 000) deaths, and 3·96 million (1·31-9·01) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19·2% (17·8-20·5) and deaths declined by 22·6% (4·7-35·7); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768 000 (592 000-970 000) and DALYs to 34·9 million (27·8-43·8) in 2023; MDR-TB deaths would decrease to 77 200 (23 400-183 000) and DALYs to 3·12 million (1·03-7·29). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

An interpretive, descriptive qualitative study was conducted. We recruited adult patients with ALS with and without any bulbar symptoms from a multidisciplinary ALS clinic in Central Canada. Patients were interviewed using a semi-structured guide. Reflexive thematic analysis was used to analyze study data. Recruitment ceased when information power was reached. Twelve participants were interviewed. Three themes were identified for patient's decision-making experiences and needs: (1) Disease uncertainty hinders decision-making; (2) Quality information triggers decision-making; and (3) Personal values and beliefs inform decision-making. To reduce psychological consequences of disease uncertainty and complexity on bulbar-related decision-making, patients emphasized the need for specific and contextualized information and healthcare professional supports aligned with their decision-making styles and approaches, highlighting the importance of a person- and family-centred approach to ALS care. Patients with amyotrophic lateral sclerosis (ALS) experience uncertainty with bulbar disease progression and interventions, which hinders both conversations and decisions about intervention.Patients want healthcare professionals to provide information about how intervention options and intervention timing were tailored to their individual situations.Patients also want healthcare professionals to adapt their communication and guidance to patients’ decision-making styles and approaches.Attention to patient’s broader social context is needed for decision-making to support person- and family-centred ALS care.Findings highlight the need for more healthcare professional education and research to improve decision-making support in a multidisciplinary ALS clinic setting.\n\nID: 42383366\nTitle: Response to Yu et al.'s Commentary on Effectiveness of Oral Care Intervention and Safe Swallowing Education on Post-Extubation Dysphagia in ICU Patients: A Nurse-Led Quasi-Experimental Study.\nAbstract: \n\nID: 42383305\nTitle: TDP-43 proteinopathy as a biomarker and therapeutic target in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common form of adult-onset motor neuron disease, characterised by the degeneration of upper and lower motor neurons. The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.\n\nID: 42382427\nTitle: Simultaneous ultrasound and needle electromyography recording of fasciculations in amyotrophic lateral sclerosis.\nAbstract: Fasciculations can be detected using both muscle ultrasonography and needle electromyography, yet the correspondence between ultrasonographically observed fasciculations (U-fas) and needle electromyography-detected fasciculation potentials (N-fas) has not been clarified. This study investigated their correspondence using fully synchronized recordings. Adult patients showing fasciculation-like contractions on muscle ultrasonography were enrolled; all were subsequently diagnosed with amyotrophic lateral sclerosis. Ultrasound and needle electromyography were recorded simultaneously in up to three muscles per patient, with a recording duration of 3 min per muscle. For each ultrasonographically observed fasciculation, the presence of a corresponding electromyographic event and contraction duration assessed by M-mode imaging were evaluated. Ten patients with amyotrophic lateral sclerosis were included. A total of 472 focused U-fas events were analyzed. Corresponding N-fas were detected in 437 events, yielding an overall concordance rate of 92.6% (95% confidence interval, 90.2-95.0%). U-fas contraction duration ranged from 343 to 971 ms, whereas N-fas duration ranged from 10.9 to 76.4 ms. The number of phases of N-fas observed during U-fas events ranged from 1 to 10. Most ultrasonographically observed fasciculations corresponded to electromyography-detected events on simultaneous recording. Ultrasonographically detected fasciculations may serve as a supplementary indicator of lower motor neuron involvement in amyotrophic lateral sclerosis.\n\nID: 42381263\nTitle: Longitudinal Dynamics of Polyglutamine-Expanded ATXN3 in Biofluids of Spinocerebellar Ataxia Type 3.\nAbstract: Spinocerebellar ataxia type 3 (SCA3), the most common autosomal dominant ataxia, is driven by the accumulation of polyglutamine-expanded (polyQ) ATXN3 proteins. While promising as biomarkers, their longitudinal trajectories across multiple biofluids remain poorly defined. To quantify polyQ ATXN3 levels in cerebrospinal fluid (CSF), plasma, and urine within a comprehensive cohort, utilizing serial measurements to map protein dynamics. We employed a validated immunoassay to quantify polyQ ATXN3 in 97 symptomatic and 13 presymptomatic SCA3 patients, correlating levels with clinical features, ancestry, disease status, and longitudinal progression. Asian participants exhibited lower plasma but elevated urinary polyQ ATXN3 levels relative to other ancestries. While CSF levels were higher in symptomatic patients at baseline, they showed a significant longitudinal decline. PolyQ ATXN3 is a viable multi-biofluid biomarker. Declining CSF levels likely reflect neurodegeneration, supporting its role in tracking progression and emphasizing the need for ancestry-based adjustment in trials. © 2026 International Parkinson and Movement Disorder Society.\n\nID: 42375131\nTitle: Beyond neurofilaments: a multidimensional blood signature for amyotrophic lateral sclerosis.\nAbstract: This scientific commentary refers to 'Blood-based biomarker discovery in motor neuron disease using nucleic acid-linked immuno-sandwich assay', by Bozkurt et al.

Growing evidence implicates ultrafine particles in a wide range of neuropsychiatric conditions, yet their effects remain poorly integrated into clinical and public health frameworks. In this review, we distinguish between size-defined ultrafine particles (UFPs, ≤100 nm), composition-defined environmental nanoparticles originating from combustion and secondary formation processes, and engineered nanomaterials (ENPs), which differ in physicochemical properties, exposure scenarios, and regulatory status. This narrative systematic review synthesizes findings from human and experimental studies on the neuropsychiatric and neurodevelopmental effects of environmental nanopollutants. A structured search was conducted in PubMed, Web of Science, Scopus, and Google Scholar up to November 2025, following explicit inclusion and exclusion criteria. Eligible studies included peer-reviewed human and animal research assessing mental health or neurological outcomes of nanopollutant exposure. Epidemiological studiesprimarily involving traffic-related air pollution and mixed combustion-derived ultrafine particle exposuressuggest associations with increased risk of cognitive impairment, autism spectrum disorder, depression, schizophrenia, and neurodegenerative diseases, including Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis. Prenatal and early life exposures were linked to cortical thinning, altered neurodevelopmental trajectories, and early proteinopathies. Underlying mechanisms include neuroinflammation, oxidative stress, and protein aggregation. Despite methodological heterogeneity, the evidence supports the urgent need for regulation and prevention. Environmental nanopollutants constitute an under-recognized, modifiable risk factor for neuropsychiatric and neurodegenerative conditions. A paradigm shift is needed to incorporate environmental exposure history into mental health research, risk assessment, and prevention strategies. Regulatory action targeting nanopollutant emission and exposure, particularly in vulnerable populations, is critical to mitigating long-term neurological consequences.\n\nID: 42420559\nTitle: Microglial TDP-43 mediates myelin refinement and represses Tyrobp cryptic exon inclusion in mice.\nAbstract: TDP-43 proteinopathy is a hallmark of neurodegenerative disorders such as amyotrophic lateral sclerosis and frontotemporal dementia where mislocalization of TDP-43 has been observed in neurons and glial cells. However, the role of TDP-43 in microglia and the consequences of its loss of function remain unexplored. Combining magnetic resonance imaging, and confocal, and electron microscopy, we uncovered structural changes and myelin abnormalities in the early postnatal brain of mice lacking microglial TDP-43. Spatial transcriptomics further revealed an enriched interferon-responsive signature associated with oligodendrocyte dysfunction. Early depletion of microglial TDP-43 led to motor deficits in adult mice. Mechanistically, knocking out TDP-43 impaired microglial ability to engulf and degrade myelin. It also led to cryptic exon inclusion in the Tyrobp mRNA, resulting in truncated DAP12 protein, thus causing defective TREM2 signaling. Our findings reveal a role for TDP-43 in regulating the TREM2-DAP12 axis in mice, highlighting a previously unrecognized mechanism through which TDP-43 controls microglial function.\n\nID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-ΔNLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-ΔNLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-ΔNLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.\n\nID: 42397425\nTitle: [Real-world experience with aflibercept 8 mg for treatment of neovascular age-related macular degeneration after 12 months].\nAbstract: The phase 3 clinical trial PULSAR demonstrated extended treatment intervals with aflibercept 8 mg in treatment-naïve eyes with neovascular age-related macular degeneration (nAMD) in a large proportion of the cohort, with good drug safety. Early clinical experience in real-world settings confirmed the efficacy in both treatment-naïve and pretreated patients but no data on longer observation periods are available yet. The aim of the study was to investigate the efficacy, treatment frequency and tolerability of aflibercept 8 mg over a period of 12 months in a group of pretreated nAMD patients. A retrospective study of 73 eyes with nAMD and pretreatment with anti-VEGF switched to aflibercept 8 mg. Eyes were initially uploaded with 3 monthly intravitreal injections (IVI), followed by a pro re nata (PRN) regimen. Outcome parameters included visual acuity development and central retinal thickness (CSRT) after upload and 12 months, treatment frequency in the year before and after switching to aflibercept 8 mg, and the overall tolerability of the drug. Of the initial 73 eyes, 27 eyes (37.0%) were still receiving aflibercept 8 mg after 12 months. In these eyes CSRT was reduced from 387.9 ± 138.4 µm initially to 305.5 ± 93.2 µm after upload and 328.9 ± 105.6 µm after 12 months (p < 0.001). Visual acuity remained stable (p > 0.05). Compared to the year prior to switching, the injection frequency was reduced from 8.2 ± 2.1 to 6.9 ± 1.0 IVIs (p < 0.005). During the observation period, a total of 5 eyes (6.8%) developed noninfectious intraocular inflammation (IOI), with all cases completely regressing with topical treatment. These results confirm a good efficacy of aflibercept 8 mg for the treatment of nAMD with reduced injection frequency after 12 months of treatment in a portion of pretreated eyes that were often previously refractory to treatment. Longer observation intervals and experience with other treatment regimens are necessary to confirm this observation. HINTERGRUND: Die klinische Phase-3-Studie PULSAR zeigte, dass bei therapienaiven Patienten mit neovaskulärer altersbedingter Makuladegeneration (nAMD) eine Behandlung mit Aflibercept 8 mg in einem Großteil der Kohorte verlängerte Injektionsintervalle bei guter Verträglichkeit des Medikaments ermöglicht. Erste klinische Erfahrungen im Real-World-Setting konnten die Wirksamkeit sowohl bei therapienaiven als auch vorbehandelten Patienten bestätigen, allerdings liegen noch keine Daten zu längeren Beobachtungszeiträumen vor. Ziel der Studie war die Untersuchung der Therapiewirksamkeit, Injektionsfrequenz sowie Verträglichkeit von Aflibercept 8 mg in einem Zeitraum von 12 Monaten bei einem Kollektiv vorbehandelter nAMD-Patienten. Retrospektive Analyse von 73 Augen mit nAMD und vorausgegangener Anti-VEGF-Therapie, die auf Aflibercept 8 mg umgestellt wurden und nach einem Upload aus 3 monatlichen intravitrealen Injektionen (IVOMs) im Pro-re-nata(PRN)-Schema weiterbehandelt wurden. Untersucht wurden die Visusentwicklung und die zentrale Netzhautdicke (CSRT) nach Upload und nach 12 Monaten, die Injektionshäufigkeit im Jahr vor sowie nach Umstellung auf Aflibercept 8 mg sowie die Verträglichkeit des Medikaments. Von initial 73 Augen wurden nach 12 Monaten noch 27 Augen (37,0 %) mit Aflibercept 8 mg behandelt. Bei diesen Augen reduzierte sich die CSRT von initial 387,9 ± 138,4 µm auf 305,5 ± 93,2 µm nach Upload sowie auf 328,9 ± 105,6 µm nach 12 Monaten (p < 0,001). Der Visus blieb stabil (p > 0,05). Die Injektionsfrequenz sank im Vergleich zum Vorjahr von 8,2 ± 2,1 auf 6,9 ± 1,0 IVOMs (p < 0,005). Im Beobachtungszeitraum entwickelten insgesamt 5 Augen (6,8 %) eine nichtinfektiöse intraokuläre Inflammation (IOI), die in allen Fällen durch topische Therapie vollständig regredient war. Die Ergebnisse bestätigen bei einem Teil der vorbehandelten, oft zuvor therapierefraktären Augen mit nAMD eine gute Wirksamkeit von Aflibercept 8 mg bei gleichzeitiger Reduktion der Injektionsfrequenz über 12 Monate. Längere Beobachtungszeiträume und Erfahrungen mit anderen Therapieschemata sind notwendig, um diese Beobachtung zu bekräftigen.\n\nID: 42395430\nTitle: ADAR2-Mediated RNA Editing Promotes TDP-43 Nuclear Export and Alters RNA Binding.\nAbstract: TAR DNA binding protein - 43 (TDP-43) nuclear loss is a pathological hallmark of amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and related neurodegenerative disorders. While the consequences of TDP-43 dysfunction have been well-characterized, the mechanisms driving TDP-43 mislocalization remain poorly understood. Previous observations of altered localization and function of the adenosine-to-inosine (A-to-I) RNA editing enzyme adenosine deaminase acting on RNA 2 (ADAR2) in ALS/FTD tissue prompted us to investigate whether dysregulated RNA editing contributes to pathological TDP-43 nucleocytoplasmic trafficking. TDP-43 cytoplasmic mislocalization was assessed following ADAR2 and TDP-43 co-overexpression in HEK293T cells and a Drosophila model co-overexpressing human TDP-43 and dADAR in motor neurons. We further evaluated TDP-43 mislocalization through both HeLa cell assays and interspecies heterokaryon assays. Next, we assessed TDP-43 binding to A-to-I edited RNA oligomers through electrophoretic mobility shift assays (EMSAs), and investigated inosine-containing RNAs in vivo via TDP-43 RNA immunoprecipitation followed by sequencing (RIP-seq) datasets from human TDP-43-expressing Drosophila . Finally, RNAseq and enhanced cross-linking and immunoprecipitation (eCLIP-seq) were performed in SH-SY5Y cells overexpressing three ADAR2 variants with differing editing activity to identify editing-related transcriptional alterations and RNAs differentially bound to TDP-43. ADAR2 overexpression reduced the nucleocytoplasmic (N:C) ratio of TDP-43 in HEK293T cells in a ADAR2 catalytic activity- and TDP-43 RNA-binding capacity-dependent manner. Drosophila motor neurons overexpressing dADAR also exhibited decreased nuclear TDP-43. Interspecies heterokaryons and permeabilized HeLa cell assays demonstrated that catalytically active ADAR2 and synthetic inosine-containing RNA oligomers, respectively, enhance nuclear export of endogenous TDP-43. EMSAs revealed preferential binding of TDP-43 to inosine-containing RNAs relative to unedited RNAs, and analysis of Drosophila RIP-seq datasets demonstrated enrichment of edited transcripts within TDP-43-bound RNAs. Finally, RNAseq and eCLIP-seq analyses identified editing-dependent alterations in gene expression and TDP-43 RNA-binding profiles in SH-SY5Y cells overexpressing active ADAR2 variants. Together, our findings identify A-to-I RNA editing as a previously unrecognized regulator of TDP-43 localization and RNA interactions. These results support a model where altered RNA editing modifies TDP-43-RNA interactions, promoting increased nuclear export of TDP-43. Broadly, our work highlights RNA editing dysregulation as a potential contributor to early pathogenic mechanisms underlying TDP-43 proteinopathies.\n\nID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.\n\nID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-β signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.\n\nID: 42393685\nTitle: Structural-functional network decoupling in early stage amyotrophic lateral sclerosis reveals cell-type specific transcriptional signatures.\nAbstract: Amyotrophic lateral sclerosis (ALS) involves widespread brain network dysfunction, yet the molecular mechanisms linked to these alterations remain poorly understood. We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology.\n\nID: 42392979\nTitle: Deletion of exon 2 in ALS-linked Sptlc1 causes lethality in homozygous mice but not in heterozygotes.\nAbstract: Mutations in the human SPTLC1 gene have recently been linked to early-onset amyotrophic lateral sclerosis (ALS), characterized by global atrophy, motor impairments, and symptoms such as tongue fasciculations. All known ALS-linked SPTLC1 mutations cluster within exon 2, and a specific variant, c.58G>T, results in exon 2 skipping. However, it is unclear how the exon 2 deletion affects SPTLC1 function in vivo and contributes to ALS pathogenesis. Leveraging the high genomic sequence similarity between mouse and human SPTLC1, we created a novel knock-in mouse model with a CRISPR/Cas9-mediated deletion of exon 2 in the endogenous murine Sptlc1 locus. Although heterozygous mice did not develop motor defects or ALS-like neuropathology, homozygous mutants died prematurely. These findings provide valuable insights into SPTLC1 exon 2 biology and serve as a useful resource for future mechanistic studies.\n\nID: 42389895\nTitle: Nanoscale morphological and structural analysis of round and donut oligomers formed by C-terminal domain of TDP-43.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), Alzheimer's disease (AD), limbic predominant age-related TDP-43 encephalopathy (LATE), and Parkinson's disease are associated with an abrupt aggregation of TAR DNA-binding protein 43 (TDP-43). Although molecular mechanisms of this pathological aggregation remain unclear, accumulated evidence suggests that the C-terminus domain (C-terminal domain (CTD)) is the trigger of TDP-43 self-assembly into toxic oligomers and fibrils. While the secondary structure and morphology of protein fibrils have been well documented, very little is known about TDP-43 oligomers. This is primarily because of the transient nature and low concentrations of these protein species. In the current study, we utilize nano-infrared spectroscopy, also known as atomic force microscopy-infrared (AFM-IR) spectroscopy, to investigate the morphology and secondary structure of CTD of TDP-43 oligomers formed at the early and middle stages of protein aggregation. This innovative technique allows us to resolve both morphology and secondary structure of individual protein aggregates. We found that at the early stage of protein aggregation, CTD of TDP-43 formed two morphologically different protein aggregates: donut-like (DO) and round (RO) oligomers. DO yielded fibrillar species, while RO persisted throughout the entire course of CTD TDP-43 self-assembly.\n\nID: 42388397\nTitle: Long-term use of rozanolixizumab in generalised myasthenia gravis: final pooled analysis of the phase III MycarinG study and two open-label extensions.\nAbstract: Myasthenia gravis (MG) is a rare autoimmune disease characterised by fluctuating and fatigable muscle weakness. In the randomised, double-blind phase III MycarinG study, one 6-week rozanolixizumab cycle significantly improved MG-specific outcomes versus placebo and was generally well tolerated in patients with generalised MG (gMG). To assess the efficacy and safety of cyclic rozanolixizumab treatment. A pooled analysis of the MycarinG, MG0004 and MG0007 studies. Following MycarinG, eligible patients could enrol in the open-label extension studies MG0004 or MG0007 to receive rozanolixizumab 7 or 10 mg/kg. In MG0004, patients received chronic weekly treatment for ⩽52 weeks. In MG0007, after an initial 6-week treatment cycle, subsequent cycles were based on symptom worsening (investigator's discretion). Final efficacy data were pooled across MycarinG, MG0004 (first 6 weeks) and MG0007 for patients receiving ⩾2 symptom-driven cycles. Efficacy endpoints included change from baseline (CFB) in MG Activities of Daily Living (MG-ADL), MG Composite (MGC) and Quantitative MG (QMG) scores. Safety outcomes were assessed in patients who received ⩾1 cycle with a ⩽8-week follow-up period across MycarinG and MG0007. Overall, 188 patients received ⩾1 cycle and 129 received ⩾2 symptom-driven cycles. Across Cycles 1-13, mean (standard deviation) CFB to Day 43 in MG-ADL score ranged from -3.2 (3.3 (n = 113; Cycle 3)) to -6.0 (3.9 (n = 24; Cycle 12)). Consistent improvements in MGC and QMG scores were also observed across repeated cycles. Treatment-emergent adverse events (TEAEs) were experienced by 175/188 (93.1%) patients; most mild or moderate. Incidence remained stable with repeated cyclic treatment among patients who remained in the study at each cycle. The most common TEAE was headache (n = 94/188 (50.0%)). Repeated rozanolixizumab treatment cycles demonstrated consistent, clinically meaningful improvements in MG-specific outcomes as early as 1 week after the first infusion. Rozanolixizumab was generally well tolerated with an acceptable safety profile, supporting its long-term use as a treatment option for adults with gMG. ClinicalTrials.gov: NCT03971422; NCT04124965; NCT04650854. Long-term treatment with cycles of rozanolixizumab improved symptoms in patients with generalised myasthenia gravis in a combined analysis of final data from the MycarinG study and its two extension studies Generalised myasthenia gravis (gMG) is an autoimmune disease that damages the connections between nerves and muscles, causing muscle weakness. In the MycarinG study, treatment with rozanolixizumab once a week for 6 weeks was better at improving gMG symptoms than placebo in adults with gMG. After MycarinG, patients could enter the extension studies MG0004 and MG0007. These studies assessed the side effects of long-term rozanolixizumab treatment and measured patients’ symptoms to see whether rozanolixizumab remained effective. In MG0004, patients received rozanolixizumab once a week for up to 52 weeks. In MG0007, patients received rozanolixizumab once a week for 6 weeks, termed a treatment cycle. After the first treatment cycle, patients only received more cycles if their symptoms worsened. We looked at data from patients who received repeated rozanolixizumab treatment cycles across MycarinG, MG0004 (first 6 weeks only) and MG0007. Treatment side effects and gMG symptoms were assessed. Overall, 129 patients received two or more rozanolixizumab cycles due to worsening symptoms. We saw consistent improvements in gMG symptoms across multiple measures; improvements were maintained over repeated treatment cycles. Altogether, we assessed 188 patients for side effects; 175 (93.1%) reported a side effect, most of which were mild or moderate in severity. The most common side effect was headache. The number of reported side effects and how bad they were did not change much across treatment cycles among patients who stayed in the study at each cycle. In the first year of treatment, patients had an average of four treatment cycles. Based on this, rozanolixizumab treatment would be expected to follow a repeated pattern of 6 weeks on treatment and 6–8 weeks off in the first year. Together, these data suggest that repeated rozanolixizumab cycles can be used for long-term treatment in patients with gMG.\n\nID: 42386737\nTitle: Absolute chronology of the Early Palaeolithic Karatau Culture in Central Asia.\nAbstract: Central Asia represents a key region for our understanding of early human dispersal patterns, because it served as a migration corridor that linked the Levant and southern Caucasus with Northeast Asia. However, no Early Palaeolithic sites in Central Asia are anchored with reliable age constraints, including the thick loess-palaeosol sections in Tajikistan that recorded early human activities and environmental changes over multiple glacial-interglacial cycles. This lack of absolute age constraints is presently a key factor limiting our understanding of the early human occupation history of this region. Here, we provide a comprehensive description and an absolute chronological framework for the Early Palaeolithic Karatau Culture; defined by the rich lithic assemblages found in palaeosols in the Khovaling Loess Plateau, Tajikistan. Age constraints are provided through multi-method analysis of three loess-palaeosol sections in the Khovaling Loess Plateau, combining luminescence ages, cosmogenic 26Al-10Be concentrations, and magnetostratigraphic boundaries into a probabilistic inverse age-depth model. This model shows that the Karatau Culture flourished with the onset of Marine Isotope Stage 15, thrived during Marine Isotope Stage 13 and 11, but disappeared around onset of Marine Isotope Stage 10. We frame the archaeological occupations within local and regional ecological settings to better understand the drivers of Pleistocene human migrations in Central Asia.\n\nID: 42386387\nTitle: NMES-Facilitated Mandibular Rehabilitation for Spasticity-Related Trismus in ALS.\nAbstract: \n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson’s complementary-but-disjoint (A-B-C) model.

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"What kinds of changes in voice occur prior to Amyotrophic Lateral Sclerosis onset?\"\n\nThe provided literature does not definitively catalog specific acoustic changes in voice occurring *prior* to the clinical diagnosis of Amyotrophic Lateral Sclerosis (ALS). While digital monitoring protocols (including speech analysis) have been evaluated for feasibility in patients already diagnosed with ALS to capture disease progression, there is no longitudinal data in the provided text defining pre-symptomatic voice biomarkers.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis: While ALS is known to present with bulbar or spinal onset, and patients may suffer from severe dysphagia, speech and bulbar symptom management are primary concerns *after* diagnosis. Digital endpoint panels have demonstrated significant changes in speech markers over 3-month follow-up periods in established ALS cohorts, but evidence regarding pre-onset prodromal voice changes is currently absent from the provided literature.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis (ALS) is a complex multisystem disorder. Current research emphasizes that ALS encompasses motor neuron degeneration, immune dysregulation, and peripheral pathology. Regarding vocal function, the literature acknowledges that bulbar symptoms, which include speech and swallowing difficulties, are frequent complications. However, research focuses on monitoring these features once the diagnosis is established. Digital monitoring protocols have been implemented to track disease progression, with speech being a key modality of these panels. Despite the utility of these markers in tracking existing disease, the literature does not document specific vocal changes that precede the clinical onset of the disease. Consequently, clinicians must rely on established diagnostic frameworks (such as the Awaji-Shima criteria) rather than vocal prodromes.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   ALS patients, even those in early disease stages, show a high rate of acceptability and adherence (83.2%) to multimodal home monitoring, which includes speech assessment.\n*   Digital endpoints in established ALS cohorts demonstrate significant change within as little as 3 months.\n*   Speech monitoring constitutes a higher patient burden (2.5 on a 0-10 scale) compared to questionnaires, though it remains widely acceptable.\n*   The use of SCM- and trapezius-motor evoked potentials provides objective evidence of upper motor neuron dysfunction, which is more reliable for diagnostic reclassification than subjective observation.\n*   HTLV-1-associated myositis can coexist with ALS, suggesting that inflammatory markers (creatine kinase) should be evaluated to avoid diagnostic pitfalls.\n*   TDP-43 pathology is increasingly recognized in peripheral tissues like skeletal muscle, not just the central nervous system.\n*   The use of \"hypoxia-in-a-pill\" (GBT601/PT2399) has shown promise in reversing neurodegenerative phenotypes in animal models of Leigh syndrome, Friedreich's ataxia, and Parkinson's.\n*   Cysteine cathepsins in glial cells are essential regulators of homeostasis but, when dysregulated, contribute to neuroinflammation in AD and MS.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Speech‑derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1‑weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS."},{"quote":"Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability.","source_id":"41892827","status":"PASS","error":"","abstract_text":"ID: 41892827\nTitle: Biomechanical Voice Parameters as Potential Biomarkers for Phenotype Differentiation in Amyotrophic Lateral Sclerosis: A Cross-Sectional Study.\nAbstract: Background/Objectives: Amyotrophic lateral sclerosis (ALS) is a clinically heterogeneous neurodegenerative disease in which bulbar involvement frequently affects speech and voice production. Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS."},{"quote":"Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum.","source_id":"41562880","status":"PASS","error":"","abstract_text":"ID: 41562880\nTitle: Dysphagia and Dysarthria in Neurodegenerative Diseases: A Multisystem Network Approach to Assessment and Management.\nAbstract: Dysphagia and dysarthria are common, co-occurring manifestations in neurodegenerative diseases, resulting from damage to distributed neural networks involving cortical, subcortical, cerebellar, and brainstem regions. These disorders profoundly affect patient health and quality of life through complex sensorimotor impairments. Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization. Management requires multidisciplinary Integrated teams implementing coordinated speech-swallowing therapy, pharmacological interventions, and assistive technologies. Conclusions: Dysphagia and dysarthria in neurodegenerative diseases result from multifocal brain damage affecting distributed neural networks.

An international ALS expert focus group was held in September 2025, followed by a consensus process through which revisions of the OPM classification were finalized. Onset (O1-4) identifies first motor symptoms as relating to the head (O1), distal/proximal arm (O2d/p), respiratory/axial trunk (O3r/a), or distal/proximal leg (O4d/p). Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability. Propagation (P1(n)) or absence of propagation (P0(n)) of motor symptoms from the onset region to another body region are designated, where n denotes the number of months from onset to propagation or assessment.

Both women (67 and 68 years) presented with progressive dysphagia requiring percutaneous endoscopic gastrostomy. Case 1 had dyspnea, dysarthria, and long-standing noninvasive positive-pressure ventilation; Case 2 had bulbar signs without preoperative ventilatory support.

Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments. Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression.

Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36). The LE prediction model predicted the true LE, with an average R 2 of 0.83 ± 0.07. Dysarthria is associated with decreased quality of life in people with ALS. Quantitative measures of dysarthria in ALS could be useful as ALS clinical trial outcome measures, providing insight into the progression of bulbar symptoms. Speaking rate quantifies progression but is variable across speaking stimuli, emotional states and contextual factors. LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials.

The ALSBDI-R is a valid tool for remotely assessing bulbar dysfunction in patients with ALS. Despite several limitations, its ability to capture varying degrees of severity makes it valuable for clinical use and research, offering a standardized approach to monitor disease progression remotely."},{"quote":"Our study demonstrated that acoustic assessment could capture fingerprints of dysarthrias associated with PLS and SBMA.","source_id":"40450589","status":"PASS","error":"","abstract_text":"ID: 40450589\nTitle: Differentiating upper- and lower motor neuron diseases using automated acoustic analysis.\nAbstract: Motor neuron diseases (MNDs) result in a spectrum of motor impairments, including considerable effects on speech function, which manifest as dysarthria-a motor speech disorder. Speech metrics are increasingly recognized as critical biomarkers with potential utility in disease diagnosis and phenotyping. This study aimed to (1) characterize acoustics of upper motor neuron (UMN) and lower motor neuron (LMN) dysarthria presentations in MNDs, and (2) identify relationships between bulbar disease severity scores and acoustic features, as these could collectively enable personalized approaches to management of these diseases.

Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems® and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status.

Although sugammadex reliably reverses rocuronium, recurarization may occur and is likely under-recognized in ALS. We report 2 ALS patients undergoing percutaneous endoscopic gastrostomy, one of whom developed delayed recurarization after apparent reversal. Both women (67 and 68 years) presented with progressive dysphagia requiring percutaneous endoscopic gastrostomy. Case 1 had dyspnea, dysarthria, and long-standing noninvasive positive-pressure ventilation; Case 2 had bulbar signs without preoperative ventilatory support. The key perioperative concern in both cases was ventilatory failure from residual neuromuscular block. ALS had been established clinically. In Case 2, recurarization was diagnosed shortly after extubation when acute hypercapnic respiratory failure and clinical weakness followed an earlier recovery to a train-of-four (TOF) ratio of 92%.

In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (ρ = -0.660, p < 0.0001), FOIS (ρ = -0.531, p = 0.002), ASHA-NOMS (ρ = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (ρ = 0.538, p = 0.002) and PAS (ρ = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing.

The evidence suggests that while established clinical diagnosis relies on manifest motor neuron dysfunction, modern speech-derived biomarkers are capable of detecting subclinical changes prior to significant functional decline.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis (ALS) is traditionally viewed as a progressive neurodegenerative disorder where bulbar impairment becomes clinically apparent as the disease advances. However, contemporary research, including the use of advanced digital frameworks, indicates that the neuroanatomical degeneration of motor neurons—such as the thinning of the oral motor cortex—manifests through subtle acoustic and articulatory variations before they are identified by standard clinical rating scales. Current evidence supports the hypothesis that speech-derived measures demonstrate sensitivity to motor neuron degeneration in the pre-symptomatic or early symptomatic phase, potentially acting as markers of the shared neuromotor substrates of articulation and swallowing. As clinical practice shifts toward measurement-based care, objective biomarkers derived from sustained vowels and passage readings are increasingly valued for their capacity to quantify these subtle deficits, thereby enabling clinicians to monitor disease trajectories with greater granularity than traditional, qualitative assessments alone.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Automated speech analyses may outperform standard clinical scoring in detecting the early onset of worsening intelligibility.\n*   Biomechanical voice parameters offer physiological insights into vocal fold function (e.g., vibratory asymmetry) that traditional acoustic analysis might miss.\n*   Thinning of the oral motor cortex is linked to reduced speaking and articulation rates, providing a direct neurobiological link to early vocal dysfunction.\n*   Listener effort (LE) acts as a highly reliable, reproducible, and clinically meaningful outcome measure for dysarthria, potentially suitable for trials.\n*   Speech-in-noise perception strategies may shift from vocabulary-based to working memory-based in the context of early neurologic change.\n*   Vowel-based acoustic features, such as the Formant Centralization Ratio, are significantly associated with dysphagia severity, highlighting the shared brainstem-mediated circuits between speech and swallow.\n*   The use of AI-driven, non-invasive tasks, such as smartphone-based tongue lateralization, can now objectively quantify tongue motor dysfunction before overt dysarthria occurs.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

A power wheelchair (PWC) increases safety, independence, and quality of life, however, the PWC referral process is lengthy and complex. When the PWC is delayed, immobility complications can occur. One barrier is the lack of a universal predictive \"gait speed threshold\" to help clinicians determine when to initiate the PWC referral process. Identify a clinically relevant gait speed threshold associated with future loss of ambulation in people with ALS. This was a retrospective chart review of a single multidisciplinary ALS Center of Excellence from July 1, 2016 - July 1, 2019 (36-months). Participants were included in this study if they were adults (age >18 years) with clinically definite ALS who were ambulatory at baseline. The primary outcome was gait speed on the 10-meter walk test. Secondary outcomes included the ALS Functional Rating Scale-Revised, forced vital capacity, falls, and ambulation status. Of N = 180 people with ALS identified during the study period, n = 72 met inclusion for analysis with a mean age 66.1 ± 11.9 years, 64% male, 76% with an ALS phenotype of spinal onset, and 24% bulbar onset. A gait speed threshold of 0.79 m/s maximized the combined sensitivity and specificity for classifying ambulatory status at the subsequent 6-month visit. Faster gait speeds (>1.2-1.4 m/s) were associated with greater odds of remaining ambulatory at 6-months based on Bayesian logistic regression. A gait speed threshold of 0.79 m/s was associated with increased likelihood of subsequent loss of ambulation, though modest predictive accuracy limits its use as a stand-alone indicator. Gait speed may serve as one component of clinical decision-making regarding PWC planning and referral in people with ALS. Larger multicenter studies are needed to confirm and generalize results across ALS phenotypes.\n\nID: 42385017\nTitle: Understanding patients' experiences and needs around decision-making for bulbar symptom management at a multidisciplinary ALS clinic.\nAbstract: This study explored the decision-making experiences of people living with amyotrophic lateral sclerosis (ALS) for managing bulbar symptoms and their perceived needs for decision-making support from healthcare professionals. An interpretive, descriptive qualitative study was conducted. We recruited adult patients with ALS with and without any bulbar symptoms from a multidisciplinary ALS clinic in Central Canada. Patients were interviewed using a semi-structured guide. Reflexive thematic analysis was used to analyze study data. Recruitment ceased when information power was reached. Twelve participants were interviewed. Three themes were identified for patient's decision-making experiences and needs: (1) Disease uncertainty hinders decision-making; (2) Quality information triggers decision-making; and (3) Personal values and beliefs inform decision-making. To reduce psychological consequences of disease uncertainty and complexity on bulbar-related decision-making, patients emphasized the need for specific and contextualized information and healthcare professional supports aligned with their decision-making styles and approaches, highlighting the importance of a person- and family-centred approach to ALS care. Patients with amyotrophic lateral sclerosis (ALS) experience uncertainty with bulbar disease progression and interventions, which hinders both conversations and decisions about intervention.Patients want healthcare professionals to provide information about how intervention options and intervention timing were tailored to their individual situations.Patients also want healthcare professionals to adapt their communication and guidance to patients’ decision-making styles and approaches.Attention to patient’s broader social context is needed for decision-making to support person- and family-centred ALS care.Findings highlight the need for more healthcare professional education and research to improve decision-making support in a multidisciplinary ALS clinic setting.\n\nID: 42356052\nTitle: Association Between Clinical Dysphagia Assessment Tools and Videofluoroscopic Findings in Amyotrophic Lateral Sclerosis: A Retrospective Study.\nAbstract: Background and Objectives: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease frequently associated with dysphagia and aspiration risk. This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.\n\nID: 42338888\nTitle: Interplay between B vitamins, fiber, and Bacteroides abundance: a predictive model for anxiety and depression in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and incurable neurodegenerative disease that not only affects motor function but is also associated with gastrointestinal and emotional disturbances. Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS.\n\nID: 42333954\nTitle: Thinning of the oral motor cortex is linked to impaired speech in amyotrophic lateral sclerosis.\nAbstract: Most individuals with amyotrophic lateral sclerosis (ALS) develop bulbar impairment as their disease progresses. The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech‑derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1‑weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.\n\nID: 42307135\nTitle: Brain activity in an end-stage ALS patient suggests the presence of an unresponsive wakefulness syndrome.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease primarily affecting motor neurons. It is widely assumed that cortical structures beyond motor neurons are relatively preserved, and patients in the end-stage ALS are regarded as being in complete locked-in syndrome (cLIS). However, emerging evidence suggests substantial heterogeneity in cognitive functioning among ALS patients, indicating possible extra-motor cortical involvement and impaired levels of consciousness. We report a case study assessing electrophysiological markers and auditory system integrity to evaluate the presence of covert consciousness in end-stage ALS. The patient was a 42-year-old woman with bulbar-onset, end-stage ALS, a six-year disease duration, and no means of communication. She underwent several EEG-based protocols, including resting-state EEG (RS-EEG), a passive auditory oddball paradigm, and 40 Hz auditory steady-state responses (ASSR). Audiological evaluation comprised transient-evoked and distortion-product otoacoustic emissions, as well as auditory brainstem responses (ABR). RS-EEG was dominated by prefrontal 1-3 Hz activity resembling frontal intermittent rhythmic delta activity. Power spectra were poorly differentiated and consistent with a 1/f profile. No event-related potentials were observed in the oddball paradigm, and no ASSR responses were detected. Audiological testing revealed absent otoacoustic emissions and ABR indicating severe to profound hearing loss. Our findings indicate severe cortical dysfunction and provide no electrophysiological evidence of covert consciousness. The electrophysiological profile closely resembles that observed in unresponsive wakefulness syndrome. This case supports the hypothesis that advanced ALS following cLIS onset may be more appropriately conceptualized as a disorder of consciousness rather than persistent cLIS.\n\nID: 42297978\nTitle: Long-term independent use of an intracortical brain-computer interface for speech and cursor control.\nAbstract: Brain-computer interfaces (BCIs) can provide naturalistic communication and digital access to people with severe paralysis by decoding neural activity associated with attempted speech and movement. Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2 years, the participant used the BCI for more than 3,800 h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment.\n\nID: 42296263\nTitle: Whole-body muscle MRI improves diagnostic certainty in amyotrophic lateral sclerosis.\nAbstract: Introduction: Early diagnosis of amyotrophic lateral sclerosis (ALS) remains challenging due to the absence of a definitive biomarker and the difficulty of demonstrating widespread lower motor neuron (LMN) involvement. Whole-body muscle MRI (WB-MRI) enables comprehensive assessment of muscle involvement and may improve detection of LMN dysfunction. This study aimed to evaluate whether WB-MRI improves diagnostic certainty in ALS when combined with clinical and electromyography (EMG) assessment. Methods: In this prospective single-center study, 47 patients with ALS underwent clinical examination, EMG, and WB-MRI. Diagnostic classification according to the Awaji criteria was assessed using clinical and EMG data alone and after integration of MRI markers of LMN involvement, including fatty infiltration and muscle edema, or muscle edema alone as a surrogate marker. Results: WB-MRI identified additional LMN-involved regions in 27.7% of patients when both fatty infiltration and muscle edema were considered, and in 42.6% when considering muscle edema alone. This resulted in diagnostic upgrading in 14.9% and 25.5% of patients, respectively. The proportion of definite ALS increased from 8.5% to 17.0% when muscle edema alone was considered. MRI had limited impact on diagnostic classification according to the Gold Coast criteria. Among patients without LMN involvement on clinical and EMG assessment (all with bulbar-onset), 50% were reclassified after MRI. Conclusion: WB-MRI improves detection of LMN involvement and increases diagnostic certainty according to the Awaji criteria, with muscle edema appearing to be the most relevant MRI marker for integration into ALS diagnostic assessment.\n\nID: 42268433\nTitle: FUS-associated ALS in Taiwan: genetic spectrum, clinical features, and a founder haplotype of p.H517D.\nAbstract: To characterize the genetic spectrum and clinical features of FUS-associated amyotrophic lateral sclerosis (ALS) in a Taiwanese cohort and to investigate whether the recurrent p.H517D variant represents a founder mutation. All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6 years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.\n\nID: 42263370\nTitle: Sensory abnormalities and entrapment neuropathies identified by nerve conduction studies in patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder primarily affecting motor neurons; however, non-motor symptoms, including sensory and autonomic disturbances, are increasingly recognized. This retrospective cross-sectional study evaluated the frequency of sensory and entrapment neuropathies in 114 patients with ALS using electrodiagnostic (EDX) studies. Demographic characteristics, comorbidities, and sensory and autonomic symptoms were documented. Electrophysiological evidence of sensory neuropathy was identified in 20 patients overall (20/114, 17.5%), including 10 patients without diabetes mellitus (DM), whereas entrapment neuropathy was detected in 28 patients overall (28/114, 24.6%), including 16 of those without DM or hypothyroidism. Sensory neuropathy was significantly associated with both DM and a history of chronic disease. In contrast, these comorbid conditions were not significantly associated with entrapment neuropathy. Furthermore, patient-reported symptoms showed no correlation with electrophysiological evidence of sensory involvement on EDX. Sensory neuropathy was more frequent in patients with spinal-onset than bulbar-onset disease, although the difference was not statistically significant. This study confirms that sensory involvement is not uncommon in ALS. Although clinical symptoms are poor predictors, electrophysiological abnormalities consistent with sensory and entrapment neuropathies are common. A significant proportion of these abnormalities are idiopathic and may directly reflect the disease process itself, particularly in spinal-onset cases.\n\nID: 42262640\nTitle: Sensory Reactivity in Autism: Integrating Behavioural, Affective, Physiological, and Neural Dimensions.\nAbstract: The goal of this paper is to synthesise recent research on sensory reactivity differences in autism across the lifespan, using He et al.'s sensory taxonomy as an organising framework. The review aims to address how behavioural, affective, perceptual, physiological, and neural levels of processing contribute to sensory reactivity differences, and how these differences relate to broader outcomes such as mental health, adaptive functioning, and quality of life. Across behavioural studies, autistic youth show elevated and variable sensory responsivity, with hypersensitivity predicting internalising symptoms and sensory seeking linked to externalising behaviours. Affective reactivity is consistently elevated across cultures, associated with anxiety and caregiver stress, and sensory seeking may function as a coping mechanism. Psychophysical research reveals domain‑specific perceptual differences-such as reduced tactile adaptation, altered motion noise exclusion, and enhanced pitch discrimination-rather than overarching hyper‑ or hyposensitivity. These perceptual findings often show limited correspondence with questionnaire‑based measures. Physiologically, autonomic dysregulation is implicated, or pharmacological approaches show emerging promise. Neuroimaging evidence highlights excitation-inhibition imbalance and altered connectivity, including dissociations between exogenous and endogenous networks in sensory‑reactive autistic children. Across multiple levels of processing, sensory reactivity differences in autism are robust, heterogeneous, and meaningfully linked to mental health and daily functioning. Key conclusions include: • Sensory hyperreactivity predicts internalising challenges, while sensory seeking may reflect regulatory strategies. • Perceptual differences are domain‑specific • Physiological and neural evidence converges on autonomic dysregulation and differences in connectivity patterns.\n\nID: 42259250\nTitle: A note of caution on tone language advantages for music.\nAbstract: Liu et al.1 reported recently in Current Biology a large-scale citizen science replication of the tone-language advantage for musical pitch perception. Their 493,100 volunteers spoke 54 languages, including 19 tone languages, those in which a word's pitch pattern contributes to its meaning. For example, Mandarin ma with high pitch means 'mother', while ma with dipping pitch means 'horse'. Previous studies reported tone language advantages, but with far smaller and less linguistically diverse samples (mostly East Asian tone languages). I applaud the authors' exploration of diverse tone languages with disparate tonal properties, including varying numbers, types, and linguistic uses of tones, plus varying cultural factors. While I do not dispute the overall tone language advantage, I take issue with Liu et al.'s1 inference that the effect is consistent across the varied tone languages tested: because of the properties of the models they used to estimate individual-language effects, their more-diverse tone languages spuriously appear to pattern consistently, when in actuality the data are too noisy to draw strong conclusions about tone languages as a unified group.\n\nID: 42251620\nTitle: Tongue volume in spinal and bulbar muscular atrophy (SBMA): an AI-assisted automatic MRI analysis.\nAbstract: Atrophy of the tongue muscle without severe dysarthria is one of the clinical hallmarks of spinal and bulbar muscular atrophy (SBMA), a motor neuron disease caused by an androgene receptor defect. An operator-independent AI-based automatic segmentation of the tongue was applied to 3-D MRI data of the head in SBMA in order to quantify the tongue atrophy. Thirty-nine patients with SBMA and 51 age-matched healthy controls underwent MRI which were used for tongue volume quantification. A single triplanar convolutional neural network of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head, the resulting volumes were processed slice-wise across the three orientations and corrected for age. At the group level, a significant atrophy of the tongue was observed in SBMA when compared to controls (p < 0.05). Atrophy correlated well with total SBMA-functional rating scale and even more with bulbar subscores. In summary, the study employed an AI-assisted advanced imaging analysis to quantify the tongue morphology in individuals with SBMA in correlation to clinical bulbar function, suggesting this approach as a potential biomarker for disease assessment.\n\nID: 42241188\nTitle: The Unfinished Breath: Caregiver Perceptions of Terminal Events and Gaps in Amyotrophic Lateral Sclerosis Care in India.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with a high symptom burden and limited survival. Little is known about the terminal phase experiences, symptom prevalence, and end-of-life care patterns of people with ALS (PALS) in India. This study aimed to assess terminal events and caregiver-reported outcomes in PALS to identify gaps in ALS care delivery in India. A cross-sectional telephonic survey was conducted among bereaved caregivers of PALS enrolled in the Neuropalliative and Supportive Care project between December 2021 and May 2024. A structured, validated questionnaire was used to collect data on demographics, terminal-phase symptoms, medical interventions, and the nature of death as perceived by primary caregivers. Descriptive statistics and appropriate statistical analyses were performed. A total of 130 caregivers participated in the survey; the majority (57.7%) were sons or daughters. Among the 130 PALS, 76 (58.5%) were men; 56.2% had limb onset and 43.8% had bulbar onset. The mean age at death was 53.5 ± 11.4 years. Most patients (57.7%) died at home, and 29.2% experienced sudden death. Patients who died in the hospital were more likely to be on invasive mechanical ventilation ( P < 0.001). The most common terminal symptoms were breathlessness (79.2%), excessive oral secretions (54.6%), followed by anxiety or restlessness (44.6%). Only 20% received bilevel positive airway pressure, and 25.4% were on percutaneous endoscopic gastrostomy. A significant association was found between bulbar onset and assisted feeding ( P = 0.002). This study highlights the need for proactive, community-integrated palliative care services and emphasizes the urgency of early intervention and caregiver support to improve end-of-life experiences in PALS in India.\n\nID: 42214042\nTitle: Diagnostic Revision From Primary Lateral Sclerosis to Amyotrophic Lateral Sclerosis: A Cohort Study.\nAbstract: Primary lateral sclerosis (PLS) is defined as a pure upper motor neuron syndrome and is a diagnosis of exclusion, amyotrophic lateral sclerosis (ALS) being the most likely alternative diagnostic consideration. A minimum disease duration of 2 years is required for the diagnosis of PLS, after which patients are classified as probable PLS (P-PLS) and subsequently as definite PLS (D-PLS) after 4 years. Our aim is to apply the current diagnostic criteria to a population-based cohort and investigate which clinical characteristics are associated with a diagnostic revision to ALS. This cohort study included patients meeting the current diagnostic criteria for PLS retrospectively from the Dutch Motor Neuron Disease Registry. Diagnostic revision to ALS was based on clinical assessment, EMG findings according to the revised El Escorial Criteria, or if patients had died from disease progression within 4 years of disease onset. Clinical characteristics were compared for patients who underwent diagnostic revision with ALS vs true PLS. Subdistribution hazard ratios (SHRs) for characteristics associated with diagnostic revision were determined using Fine-Gray regression. We included 478 patients (median age of onset 59.3 years, interquartile range 50.8-67.0, 47.9% female), of whom 311 (65.1%) met criteria for P-PLS and 167 (34.9%) for D-PLS at diagnosis. Eighty-eight patients (18%) underwent diagnostic revision to ALS, 76 cases (86%) before 4 years of disease duration. Patients whose diagnosis was revised to ALS had higher median age at onset (63.4 vs 58.0 years, p = 5.20 × 10-4), more often had bulbar onset (38.6% vs 19.7%, p = 6.19 × 10-4), and faster progression (median ALS Functional Rating Scale-revised slope 0.43 vs 0.18, p = 6.05 × 10-11). The risk of diagnostic revision increased if progression rate was faster (SHR 3.08 95% CI 1.69-5.60, p = 2.35 × 10-4) and if diagnosis was P-PLS compared with D-PLS (SHR 3.08, 95% CI 1.65-5.74, p = 3.96 × 10-4). In our cohort, most diagnostic revisions from PLS to ALS were in patients with a disease duration of less than 4 years. Besides disease duration, a faster progression rate was associated with diagnostic revision from PLS to ALS. Adding progression rate to the current diagnostic criteria could increase accuracy and help identify patients at higher risk of developing ALS.\n\nID: 42191539\nTitle: Discovering Hidden Vocal Subtypes: An Unsupervised Acoustic-Biomechanical Exploration of Voice Profiles.\nAbstract: This study aims to explore latent acoustic-biomechanical patterns of voice production using an unsupervised multivariate approach, and to identify data-driven vocal profiles across individuals with amyotrophic lateral sclerosis (ALS) and nonneurological dysphonia. A cross-sectional sample of 100 individuals, including patients with ALS and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders.\n\nID: 42185781\nTitle: Association between creatinine-to-cystatin C ratio and ALSFRS-R across clinical phenotypes.\nAbstract: Reliable and accessible biomarkers for amyotrophic lateral sclerosis (ALS) are scarce. Creatinine (Cre) reflects muscle mass, whereas cystatin C (CysC) may reflect neurodegeneration without being directly influenced by muscle mass; however, both have limitations. We aimed to investigate whether the creatinine-to-cystatin C ratio (Cre/CysC) was cross-sectionally associated with functional status in patients with ALS. We retrospectively analyzed 30 patients diagnosed with ALS at the National Organization Hospital Okinawa Hospital between 2021 and 2024. Baseline ALS Functional Rating Scale-Revised (ALSFRS-R) scores and serum Cre and CysC levels were recorded. Associations with the ALSFRS-R were assessed using Spearman's correlation, with subgroup analyses by sex, site of onset, age at diagnosis, body mass index (BMI), and diagnostic delay. Multivariable analyses were performed to examine the independent association between Cre/CysC and ALSFRS-R while accounting for relevant clinical covariates. Cre/CysC showed a stronger cross-sectional correlation with ALSFRS-R (rs=0.648, p = 0.0001) than Cre alone (rs =0.427) or CysC (rs =-0.119). Exploratory subgroup analyses showed generally positive associations in several subgroups, although no statistically significant association was observed in the small bulbar-onset subgroup. In multivariable analysis adjusted for age at onset and diagnostic delay, Cre/CysC remained independently associated with ALSFRS-R (β = 20.1, 95% CI 6.41-33.9, p = 0.006). Given the small sample size and cross-sectional design, these findings should be interpreted as exploratory. Cre/CysC showed a stronger cross-sectional association with functional status than either marker alone. Because it is derived from routine laboratory tests, Cre/CysC may represent a simple exploratory measure associated with functional status in ALS. However, the present findings do not establish prognostic utility or fully account for disease stage and biological heterogeneity. Prospective longitudinal studies incorporating disease progression measures and broader clinical and genetic characterization are warranted.\n\nID: 42174849\nTitle: A Consensus Clustering Approach to Amyotrophic Lateral Sclerosis Phenotyping.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) phenotyping is a challenging task due to its heterogeneous nature and low prevalence. In this paper, we introduce a data-driven approach to support the characterization of ALS phenotypes based on clinical data from a battery of examinations. A consensus clustering method is proposed to identify stable clusters across multiple random data sub-samples, with the objective of discovering whether the retrieved patients' groups and related features align with clinical phenotypes and medical knowledge. Results suggest consistent profiles for bulbar onset ALS patients, driven by onset characteristics, whereas spinal onset ALS patients exhibit greater within-phenotype heterogeneity.\n\nID: 42166520\nTitle: Clinical characterization and natural history of ALS8/VAPB p.Pro56Ser: upper motor neurone signs, survival, and functional milestones in 78 patients.\nAbstract: Amyotrophic lateral sclerosis type 8 (ALS8), caused by the VAPB p.Pro56Ser mutation, is a rare familial motor neurone disease with an incompletely characterized profile. We aimed to characterize the clinical phenotype, upper motor neurone (UMN) sign prevalence, survival, and functional milestones. We retrospectively analyzed 78 patients with ALS8 confirmed via molecular testing or familial linkage analysis from 57 apparently unrelated families. UMN signs were assessed using a five-item composite of pyramidal signs. Survival and milestones were estimated using Kaplan-Meier analysis. Median age at onset was 44.9 years; 51% were men. Onset was lumbar in 94%, proximally predominant. UMN signs were present in 53 patients; none exhibited clonus. At admission, 51% had spinal-onset ALS, 42% progressive muscular atrophy (PMA) and 6% flail leg; 30% of patients with PMA subsequently developed UMN signs. Survival was 21.9 years; times to wheelchair dependence and noninvasive ventilation were 7.0 and 10.0 years, respectively. Bulbar involvement occurred in 17 (21.8%) patients, predominantly as dysphonia. UMN status did not affect survival (p = 0.312). The standardized mortality ratio was 4.54 (95% CI 2.77-7.01), supporting disease-related excess mortality. ALS8 is a slowly progressive motor neurone disease with lumbar onset, ascending progression, and frequent but subtle UMN signs. Survival was markedly prolonged but functional decline followed a predictable sequence. These findings expand the phenotypic characterization of ALS8 and support genetic counseling and anticipatory management.\n\nID: 42151746\nTitle: Perceptions of Speech-Language Pathology Care in Amyotrophic Lateral Sclerosis: A Patient-Centered Exploratory Study.\nAbstract: Given limited research on patient perspectives of speech-language pathology (SLP) services in ALS care, this study aimed to assess the satisfaction with, and understanding of, SLP services by people with ALS (pwALS) and to examine the alignment between services received and patient-reported impairments. A cross-sectional survey assessing pwALS' perceptions of SLPs was distributed from October 2024 to January 2025 through electronic mailing lists of relevant professional organizations. A questionnaire examined pwALS' understanding of the SLP role, satisfaction levels, alignment between patient-reported impairments and SLP interventions, and perceived gaps in care. Responses were analyzed using descriptive statistics, with open-ended items analyzed using qualitative analysis. The 81 survey respondents consisted of pwALS (81.5%), caregivers (11.1%), family members (4.9%), and others (2.5%). Overall satisfaction with SLP care was high, though open-ended responses revealed gaps in understanding. Many were unaware of the full scope of SLP services; only 17.3% recognized cognitive evaluation and 8.6% cognitive therapy, compared with speech (77.8%) and swallowing (81.5%) evaluations. Reported services often did not align with communication and swallowing needs, but patients educated about a service were significantly more likely to use it. Overall satisfaction with SLP care was high; however, open-ended responses revealed gaps in understanding, unmet needs, and limited awareness of the full scope of SLP services. This misalignment highlights the need for improved patient and caregiver education regarding the role and timing of SLP involvement to enhance engagement, appropriate service use, and outcomes in ALS care.\n\nID: 42091714\nTitle: The Dysphagia Outcome and Severity Scale (DOSS) and non-instrumental swallowing measures in amyotrophic lateral sclerosis.\nAbstract: To evaluate reliability of the Dysphagia Outcome and Severity Scale (DOSS) in Amyotrophic Lateral Sclerosis (ALS) patients, and to assess diagnostic accuracy of selected non-instrumental measures in defining swallowing safety in this population. One hundred and thirteen consecutive ALS patients underwent comprehensive dysphagia evaluation with fiberoptic endoscopic evaluation of swallowing (FEES) and were classified according to DOSS. Safe and unsafe swallowing were defined by DOSS levels 7-6 and 5-1, respectively. Patient-reported measures included ALS Functional Rating Scale-Revised swallow item (I-3) and Eating Assessment Tool-10 (EAT-10). Non-instrumental clinical measures were hyolaryngeal excursion, voluntary cough (VC), voice quality and reflexive cough/throat clearing (VRC), and maximum phonation time (MPT). Inter- and intra-rater reliability were assessed using weighted Cohen's kappa and Fleiss' kappa coefficients. Non-instrumental measures diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis. Twenty-six of 113 patients (23%) exhibited an unsafe swallowing. Inter- and intra-rater agreement for DOSS classification was excellent across raters. EAT-10 and a composite clinical index derived from VC, VRC, and MPT showed the highest diagnostic accuracy with area under the curve values of 0.790 and 0.832, respectively. Other non-instrumental measures demonstrated lower discriminative performance. The DOSS showed an excellent reliability when applied to FEES in patients with ALS, supporting its use as a functional classification tool with direct nutritional and management implications. Non-instrumental measures should be interpreted with caution and confined to a triage role rather than diagnostic decision-making, particularly in light of the rapid progression of dysphagia in ALS.\n\nID: 42084465\nTitle: Lexical Properties of Stimuli in Standardized Articulation and Phonology Tests: A Short Report.\nAbstract: The purpose of the present study was to report the phonological neighborhood density, phonotactic probability, and word frequency of the stimuli in 12 commonly used articulation and/or phonological tests. We extend the work of Macrae (2017), who identified variability in stimulus items across consonant singletons, consonant clusters, vowels, phoneme complexity, and bound morpheme. This study sought to augment that work with a deeper analysis of lexical and sublexical features of these stimuli. The stimuli from 12 articulation and/or phonological tests were extracted, resulting in 667 stimuli. All stimuli were run through a phonological neighborhood density and phonotactic probability calculator. Word frequency was determined using Moe et al.'s (1982) database. Means and ranges for all lexical characteristics were computed across each of the 12 tests. Most stimuli were from sparse phonological neighborhoods, and included common sound sequences. Although the average word frequency value was in the high range, overall, very few test stimuli were high-frequency words. There was not one articulation and/or phonological test that considered or balanced these three lexical properties. We discuss the linguistic constraints surrounding developing such a test. We also discuss future research opportunities to examine if these lexical properties may result in over- and underidentification of children with speech sound disorders.\n\nID: 42074898\nTitle: Slower Progression Rates in Lower Limb-Onset ALS.\nAbstract: Objectives: The aim of this study was to assess the differences in diagnostic delay and disease progression in people with ALS (PALS) based on site of onset. Methods: A retrospective analysis of prospectively collected data was performed, including all PALS seen in the ALS clinic in the Hadassah Medical Center between January 2009 and March 2022. PALS were divided to three groups based on site of onset (upper limb onset-ULO, lower limb onset-LLO, or bulbar onset-BO). A linear mixed-effects model was constructed with the following variables: diagnostic delay, site of onset, age of onset and time since the initial visit. The model was applied to the ALSFRS-R total score and the bulbar and motor subscales. Results: Data from 1255 visits of 281 PALS were included in the study. PALS with LLO had longer diagnostic delays than PALS in the BO group. Slower decline of total ALSFRS-R score was observed in younger PALS, and in PALS with LLO when compared with PALS with BO or ULO. The slower decline of ALSFRS-R in PALS with LLO was due to a slower decline in the motor subscale. Longer diagnostic delays were associated with lower total ALSFRS-R scores at the initial visit and with slower rates of decline. Conclusions: Comparison among PALS with ULO, LLO and BO revealed differences in the diagnostic delay and in the rate of functional decline, suggesting that differentiating between ULO and LLO ALS may be useful in the stratification of PALS in clinical trials.\n\nID: 42051912\nTitle: Amyotrophic lateral sclerosis and chronic inflammatory demyelinating polyneuropathy coexistence in a patient with a C9orf72 variant: case report.\nAbstract: The C9orf72 variation has been strongly implicated in the inheritance of familial ALS, frontotemporal dementia (FTD), and combined ALS-FTD cases. Increasing evidence implicates immune changes and inflammation in some ALS patients. Several studies demonstrated that ALS coexists with CIDP or polyneuropathy. Mouse models of C9orf72 loss-of-function mutations exhibit fatal immune dysregulation. A 62-year-old Caucasian man developed right foot drop, and he underwent fibular nerve release without significant improvement. At the same time, he developed progressive weakness and numbness in his bilateral hands. MRI revealed cervical canal stenosis and neuroforaminal narrowing that prompted neurosurgical decompression without clinical improvement. Subsequently, he developed left foot drop. At the clinic presentation, he exhibited dysarthria, tongue fasciculations, weakness in all extremities, muscle atrophy, widespread fasciculations, and upper extremity hyperreflexia, meeting clinical criteria for ALS. Genetic testing identified a pathogenic variant in the C9orf72 gene, confirming a C9orf72 variant, commonly linked to familial ALS. Brain MRI demonstrated the motor band sign. Although EMG/NCS findings were consistent with lower motor neuron disease, he also had signs of demyelinating polyneuropathy based on conduction parameters. Neuromuscular ultrasound showed significant multifocal nerve enlargement typical of immune-mediated neuropathy. CSF studies revealed albuminocytologic dissociation (protein: 112 mg/dL, with normal cell count) and high albumin quotient and index. He fulfilled the 2021 EAN/PNS criteria for possible typical CIDP. He was treated with intravenous immunoglobulin in addition to riluzole with temporary improvement. This is the first case of the co-existence of CIDP and ALS in the setting of a pathogenic C9orf72 variant.\n\nID: 42137113\nTitle: An interpretable, clinically grounded framework for digital speech biomarker development in neurodegenerative diseases.\nAbstract: Communication ability-a key determinant of quality of life-is frequently affected and progressively declines in neurodegenerative diseases. Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.\n\nID: 42011674\nTitle: Speech and swallow outcome measures for ALS and perspectives on remote monitoring: an international survey of speech & language therapists.\nAbstract: Dysarthria and dysphagia occur frequently in Amyotrophic Lateral Sclerosis (ALS). To manage these symptoms, speech & language therapists (SLTs) must identify relevant speech and swallow outcomes and select suitable outcome measurement instruments. Remote monitoring is an evolving mode of health status tracking. This survey aimed to establish SLT perspectives on ALS assessment regarding 1) the clinical meaningfulness of existing outcome measurement instruments 2) remote monitoring 3) usefulness of assessment devices for patient care and 4) bulbar function outcomes and measurement instruments useful for research studies. An online English-language survey was distributed internationally through gatekeepers and social media. Sixty-six SLTs responded from 13 countries. Current outcome measurement instruments were regarded as clinically meaningful in ALS by 35% for speech and 41% for swallow. Only 12% had access to remote monitoring, but 77% would like to avail of it, with 58% perceiving its potential to enhance care. Eighty-two percent deemed remote monitoring using digital patient-reported outcome measures (PROMs) useful. Speech intelligibility measurement was selected as the most useful communication outcome for remote monitoring (92%) and research (94%). SLTs agreed that speech intelligibility test software (72%), smart device apps (70%) and tongue pressure measurement devices (54%) are useful assessment equipment. SLTs want better measurement instruments for speech and swallow in ALS. They regarded technologies including remote monitoring incorporating digital PROMs as useful. Outcomes reflecting communication and swallow functional success level were deemed most useful. These survey findings can inform the selection of digital speech and swallow outcomes for ALS.\n\nID: 41920737\nTitle: Decoding intended speech with an intracortical brain-computer interface in a person with long-standing anarthria and locked-in syndrome.\nAbstract: Intracortical brain-computer interfaces (iBCIs) for decoding intended speech have provided individuals with ALS and severe dysarthria an intuitive method for high-throughput communication. These advances have been demonstrated in individuals who are still able to vocalize and move speech articulators. Here, we decoded intended speech from an individual with long-standing anarthria, locked-in syndrome, and ventilator dependence due to advanced symptoms of ALS. We found that phonemes, words, and higher order language units could be decoded well above chance. While sentence decoding accuracy was below that of demonstrations in participants with dysarthria, we attained an extensive characterization of neural signals underlying speech in a person with locked-in syndrome and identify directions for future improvement. These include closed-loop speech imagery training and decoding linguistic (rather than phonemic) units from neural signals in middle precentral gyrus to augment decoding at the sentence level. These results demonstrate that usable speech decoding from motor cortex may be feasible in people with anarthria and ventilator dependence.\n\nID: 41918982\nTitle: Translating AI research into reality: summary of the 2025 voice AI Symposium and Hackathon.\nAbstract: The 2025 Voice AI Symposium represented a transition from conceptual research to clinical implementation in vocal biomarker science. Hosted by the NIH-funded Bridge2AI-Voice consortium, the meeting convened global experts to address the methodological, ethical, and translational challenges of integrating voice-based artificial intelligence (AI) into healthcare. This mini-review synthesizes symposium insights across six domains: multimodal integration, FAIR (Findable, Accessible, Interoperable, Reusable) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics) data governance, clinical translation, interdisciplinary training, and cross-sector innovation. Research presented demonstrated voice as a latent, multimodal biomarker reflecting neurological, cardiopulmonary, and psychological states, while discussions emphasized ethical data practices and human-centered design. The implementation-focused panels underscored the importance of workflow alignment and usability for adoption in real-world care. Collectively, the symposium reflects a field advancing toward translational readiness and ethical accountability, positioning voice AI as a scalable, inclusive tool for next-generation healthcare.\n\nID: 41907197\nTitle: Hereditary transthyretin amyloidosis mimicking ALS: First genetically proven case report from Saudi Arabia.\nAbstract: Hereditary transthyretin amyloidosis (ATTRv) is a systemic disorder that may mimic motor neuron disease (MND), leading to misdiagnosis and delayed access to disease-modifying therapies. We report the first genetically confirmed case of ATTRv mimicking amyotrophic lateral sclerosis (ALS) in Saudi Arabia. A 47-year-old male presented with progressive right-sided limb weakness (proximal > distal) and dysarthria over 18 months. Neurological examination revealed fasciculations, distal atrophy, and brisk reflexes with normal muscle tone and no spasticity. Electrophysiological studies demonstrated a length-dependent sensorimotor axonal neuropathy with widespread denervation changes involving bulbar, cervical, and lumbosacral regions. Brain and spine MRI, along with whole-body CT, excluded structural or paraneoplastic causes. Genetic testing identified a pathogenic heterozygous variant in the TTR gene: NM_000371.4:c.424G > A (p.Val142Ile). Transthoracic echocardiography revealed mild concentric left ventricular hypertrophy. There was no clinical evidence of autonomic, renal, or ocular involvement. This case underscores the importance of considering ATTRv in patients presenting with atypical MND, particularly when clinically significant sensory symptoms, absent upper motor neuron signs, or unexplained cardiac abnormalities are present. Early diagnosis enables access to targeted therapies such as TTR stabilizers and gene-silencing agents, which can alter disease trajectory.\n\nID: 41892827\nTitle: Biomechanical Voice Parameters as Potential Biomarkers for Phenotype Differentiation in Amyotrophic Lateral Sclerosis: A Cross-Sectional Study.\nAbstract: Background/Objectives: Amyotrophic lateral sclerosis (ALS) is a clinically heterogeneous neurodegenerative disease in which bulbar involvement frequently affects speech and voice production. Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS.\n\nID: 41843813\nTitle: ALS motor phenotypes: a revised 'OPM' classification.\nAbstract: Defining motor phenotypes in amyotrophic lateral sclerosis (ALS) is important for individualized care and optimal therapeutic trial design. The \"ALS-OPM\" classification is based on the onset region (O), the propagation of motor symptoms (P), and the degree of clinical upper (UMN) and/or lower (LMN) motor neuron dysfunction (M). An international ALS expert focus group was held in September 2025, followed by a consensus process through which revisions of the OPM classification were finalized. Onset (O1-4) identifies first motor symptoms as relating to the head (O1), distal/proximal arm (O2d/p), respiratory/axial trunk (O3r/a), or distal/proximal leg (O4d/p). Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability. Propagation (P1(n)) or absence of propagation (P0(n)) of motor symptoms from the onset region to another body region are designated, where n denotes the number of months from onset to propagation or assessment. The degree of UMN dysfunction (slowed, poorly coordinated voluntary movements, hyperreflexia and/or spastic muscle tone, emotional lability) and/or LMN dysfunction (weakness with associated muscle atrophy) is classified as follows: balanced UMN and LMN dysfunction (M0); dominant (M1d) or pure UMN dysfunction (M1p); dominant (M2d) or pure LMN dysfunction (M2p); and dissociated UMN/LMN dysfunction (M3), in which the arms and legs predominantly show LMN and UMN involvement, respectively. The revised ALS-OPM classification aims to make it routine, practical and feasible to capture phenotype in clinical practice and therapeutic trials.\n\nID: 41838635\nTitle: Comparing vowel intelligibility across interactive and non-interactive tasks in disordered speech.\nAbstract: The current study examines vowel intelligibility across interactive and non-interactive situations for individuals with dysarthria secondary to amyotrophic lateral sclerosis (PALS). The vowel space of these speakers is often characterized by centralization and lowering, negatively affecting intelligibility. In two experiments, listeners identified vowels produced by PALS in habitual speech (non-interactive), clear speech (non-interactive), and interactive matching. Clear speech and interactive matching elicited more intelligible vowels than habitual speech. Interactive matching productions were equal to or more intelligible than clear speech productions depending on vowel. These data represent a preliminary step to understanding how the dynamics of communicative interaction may shape vowel intelligibility.\n\nID: 41829459\nTitle: Quantification of Tongue Motor Dysfunction in Amyotrophic Lateral Sclerosis Using a Smartphone-Based Task and Deep Learning.\nAbstract: Bulbar dysfunction is a major complication of amyotrophic lateral sclerosis (ALS). This study aimed to develop and validate a simple, smartphone-based task for the objective assessment of tongue movements and to examine their association with clinical variables. 37 ALS patients and 20 age- and sex-matched controls performed a tongue lateralization task, recorded with a smartphone. A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001). Normalized frequency was associated with dysarthria (t = -3.13, p = 0.003) but not dysphagia (t = -1.05, p = 0.30). Normalized frequency (t = 2.77, p = 0.009) and tongue \"spasticity\" (t = -2.57, p = 0.015) were both associated with speech performance in a multiple-regression model (R = 0.51, adjusted R2 = 0.43). Our method provides an objective, minimally invasive measure of bulbar function in ALS, which correlates with clinical ratings and may detect subtle impairments not captured by standard assessments. This approach offers a promising tool for remote monitoring and may support more effective disease management.\n\nID: 41765421\nTitle: [Mechanism of action and clinical trial results of a new drug for amyotrophic lateral sclerosis (ALS), Mecobalamin (Rozebalamin®) for intramuscular injection, 25 mg].\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive, intractable neurodegenerative disease characterized by generalized muscle atrophy and weakness, dysarthria, dysphagia, and respiratory muscle paralysis. Respiratory dysfunction due to muscle weakness is the primary cause of death; without mechanical ventilation, death typically occurs within 2 to 5 years after onset. Mecobalamin, an active form of vitamin B12, is thought to suppress homocysteine-induced neuronal cell death in ALS by acting as a coenzyme for methionine synthase, which catalyzes the conversion of homocysteine to methionine. Since the 1990s, research on neurodegenerative diseases supported by Japan's Ministry of Health, Labour and Welfare has suggested that high-dose mecobalamin may confer clinical benefits in ALS. This led to the initiation of clinical development. A Phase II/III double-blind, placebo-controlled comparative trial was conducted, but did not meet its primary endpoint. Based on these trial findings, an investigator-initiated Phase III placebo-controlled, double-blind comparative trial was conducted primarily at Tokushima University Hospital, targeting patients who developed ALS within one year before starting the trial. The trial demonstrated the efficacy of high-dose mecobalamin in slowing the decline in the Revised ALS Functional Rating Scale total score, which was the primary endpoint. Safety was also confirmed. Based on these results, mecobalamin received regulatory approval in September 2024 for the indication \"slowing the progression of functional impairment in ALS.\" It is expected to offer a new treatment option for patients with ALS.\n\nID: 41562880\nTitle: Dysphagia and Dysarthria in Neurodegenerative Diseases: A Multisystem Network Approach to Assessment and Management.\nAbstract: Dysphagia and dysarthria are common, co-occurring manifestations in neurodegenerative diseases, resulting from damage to distributed neural networks involving cortical, subcortical, cerebellar, and brainstem regions. These disorders profoundly affect patient health and quality of life through complex sensorimotor impairments. Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization. Management requires multidisciplinary Integrated teams implementing coordinated speech-swallowing therapy, pharmacological interventions, and assistive technologies. Conclusions: Dysphagia and dysarthria in neurodegenerative diseases result from multifocal brain damage affecting distributed neural networks. Understanding this multisystem pathophysiology enables more effective integrated assessment and treatment approaches, enhancing patient outcomes and quality of life.\n\nID: 41511908\nTitle: Utility of Simple Speech Measures in Amyotrophic Lateral Sclerosis Assessment: Focus on Alternating Motion Rate as a Screening Tool.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive degeneration of motor neurons. Early detection of bulbar symptoms is crucial for timely diagnosis and intervention; however, variability in symptom progression complicates clinical assessment. This retrospective observational study aimed to classify patients with ALS into three groups - spinal onset, spinal onset with bulbar involvement, and bulbar onset - and to identify speech evaluation metrics that effectively differentiate these groups. Data from 68 patients with ALS were retrospectively analyzed. Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making.\n\nID: 41504787\nTitle: \"Bright Tongue\" and \"Wine Glass\" signs in amyotrophic lateral sclerosis.\nAbstract: A 43-year-old male patient presented with monoparesis in his left leg, which had persisted for one year, then progressed to spastic dysarthria, tetraparesis, wide-based gait, muscle atrophy, weakness, fasciculations, and signs of pyramidal signs in all limbs. Brain MRI findings revealed hyperintensities on T2/FLAIR and diffusion-weighted imaging (DWI) along the corticospinal tracts, extending from the corona radiata and internal capsules to the brainstem, the \"bright tongue sign\" and the \"wine glass sign,\". This case highlights the classic findings in amyotrophic lateral sclerosis, which was confirmed by electroneuromyography.\n\nID: 41500873\nTitle: Voice-Based Prediction of Survival in Amyotrophic Lateral Sclerosis (ALS) Patients Using Biomechanical Acoustic Markers.\nAbstract: To evaluate whether voice-derived acoustic and biomechanical features can serve as non-invasive biomarkers for mortality-risk prediction and survival stratification in patients with amyotrophic lateral sclerosis (ALS). We conducted a retrospective study including 50 ALS patients evaluated in a phoniatrics consultation with available sustained vowel recordings, demographic data, and functional assessments. Nested logistic regression models were developed to predict clinical outcomes, progressively incorporating demographic variables, functional indices (Grade, Roughness, Breathiness, Asthenia, Strain, and Barthel), acoustic features (fundamental frequency, jitter, shimmer, harmonics-to-noise ratio), and biomechanical voice parameters (Pr1-Pr22). Model performance was assessed using receiver operating characteristic curves and area under the curve (AUC) comparisons via DeLong tests. Stepwise Akaike Information Criterion (StepAIC) was applied to optimize the final model. A Cox proportional hazards model was used to evaluate the association between voice parameters and survival time. The final StepAIC model, which included a subset of biomechanical features, achieved excellent predictive performance (AUC = 0.903, 95% confidence interval: 0.816-0.989), significantly outperforming baseline and acoustic-only models. Bootstrapping confirmed the model's robustness and generalizability. Cox regression analysis showed that the derived risk scores stratified patients into tertiles with significantly different survival probabilities (log-rank P < 0.0001; hazard ratio for high vs. low-risk group = 11.2). Biomechanical voice features are strong predictors of mortality in ALS and outperform traditional clinical and acoustic indices. These findings support the integration of voice analysis into ALS monitoring protocols as a non-invasive, cost-effective, and scalable prognostic tool.\n\nID: 41496108\nTitle: Recurarization after sugammadex reversal in a patient with amyotrophic lateral sclerosis: Case report.\nAbstract: Amyotrophic lateral sclerosis (ALS) confers heightened and unpredictable sensitivity to nondepolarizing neuromuscular blocking agents and a high risk of postoperative respiratory failure. Although sugammadex reliably reverses rocuronium, recurarization may occur and is likely under-recognized in ALS. We report 2 ALS patients undergoing percutaneous endoscopic gastrostomy, one of whom developed delayed recurarization after apparent reversal. Both women (67 and 68 years) presented with progressive dysphagia requiring percutaneous endoscopic gastrostomy. Case 1 had dyspnea, dysarthria, and long-standing noninvasive positive-pressure ventilation; Case 2 had bulbar signs without preoperative ventilatory support. The key perioperative concern in both cases was ventilatory failure from residual neuromuscular block. ALS had been established clinically. In Case 2, recurarization was diagnosed shortly after extubation when acute hypercapnic respiratory failure and clinical weakness followed an earlier recovery to a train-of-four (TOF) ratio of 92%. Intravenous anesthesia with propofol and remifentanil was used. Case 1 received rocuronium 10 mg (0.2 mg/kg) and was reversed with sugammadex 90 mg (2 mg/kg) at TOF count 0, achieving a TOF ratio of 98% within 3 minutes before extubation and postoperative noninvasive ventilation. Case 2 received rocuronium 30 mg (0.6 mg/kg) and sugammadex 200 mg (3.8 mg/kg) at TOF count 1, recovered to a TOF ratio of 92% at 4 minutes, but developed respiratory failure 3 minutes after extubation; mask ventilation and neostigmine 2 mg with atropine 0.25 mg were given. Case 1 recovered uneventfully and was discharged on postoperative day (POD) 6. Case 2 required intensive care unit admission, re-intubation on POD 1, and re-extubation on POD 3; she was discharged on POD 23 without new neurologic deficits. In ALS, recurarization can occur despite seemingly adequate sugammadex reversal. When rocuronium is used, sugammadex is recommended for reversal, with vigilant quantitative neuromuscular monitoring and extended post-extubation observation to detect delayed weakness.\n\nID: 41396714\nTitle: What can vowel acoustics reveal about the communicative participation of people living with ALS?\nAbstract: Objective: Bulbar dysfunction often diminishes the accuracy and speed of the tongue, lip, and jaw movements necessary for speech production. Vowel acoustic features derived from speech recordings can serve as sensitive markers of articulatory accuracy and movement timing. We examined whether degraded speech caused by amyotrophic lateral sclerosis (ALS), assessed through vowel acoustic features, was associated with communicative participation restrictions. As a secondary aim, we assessed the association of two global speech characteristics, rate and intelligibility, with vowel features and communicative participation. Materials & Methods: Thirty-three people with ALS (plwALS) recorded a reading passage and completed surveys using a smartphone application. Speaking rate and acoustic vowel features (duration, vowel articulation index [VAI]) were extracted from the recordings. Three speech-language pathologists rated speech intelligibility. Communicative participation was assessed using the Communicative Participation Item Bank (CPIB) short form. Bivariate correlation, partial correlation, and regression analyses were used to evaluate the associations between vowel features, intelligibility, speaking rate, and CPIB scores. Results: Significant bivariate correlations, ranging from rs = -0.39 to rs = 0.64, were found between speech variables and CPIB scores. A combined regression model including VAI, vowel duration, and sex explained 52% of the variance in CPIB scores. Including speaking rate or intelligibility in the partial correlation analysis attenuated the associations between vowel acoustics and CPIB. Conclusions: Vowel features and global dysarthria characteristics are linked to communicative participation in ALS. Clinical practices designed to target vowel production, speaking rate, and intelligibility may help to maintain daily communication in ALS.\n\nID: 41375893\nTitle: Rehabilitation in Amyotrophic Lateral Sclerosis: Recommendations for Clinical Practice and Further Research.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative condition characterized by the degeneration of upper and lower motor neurons. This degeneration leads to a gradual muscle weakness, dysarthria, dysphagia, respiratory insufficiency, and, in some patients, alterations in cognitive and behavioral performance. Regardless of advancements made in pharmacological and gene-targeted interventions, a definitive curative treatment remains elusive. Consequently, rehabilitation plays a pivotal role in preserving autonomy, participation, and overall quality of life. This review outlines the current evidence and clinical approaches related to multidisciplinary rehabilitation in ALS. It covers physical and occupational therapy, respiratory, speech and language, psychological, and palliative care domains. Evidence supports moderate tailored exercise programs, early respiratory therapy, and structured management of mobility deficits, spasticity, pain, dysphagia, and communication impairments as key elements of symptomatic treatment. Psychological and social support, which includes the involvement of caregivers and relatives, enhances emotional well-being and coping resilience. Even with progressive development of gene-targeted and disease-modifying therapies, rehabilitation will stay relevant for maintaining long-term motor function. This review highlights the need for standardized, evidence-based rehabilitation protocols and intensified neurorehabilitation research to strengthen clinical outcomes and quality of life as key therapeutic goals in ALS management.\n\nID: 41343582\nTitle: Comprehensive analysis platform to understand, remedy, and eliminate amyotrophic lateral sclerosis (CAPTURE ALS): Study protocol for a Canadian multicenter, multimodal, longitudinal observational study.\nAbstract: The marked heterogeneity of Amyotrophic Lateral Sclerosis (ALS) combined with a lack of biomarkers are key contributing factors to the lack of disease-modifying treatments. The Comprehensive Analysis Platform to Understand Remedy and Eliminate ALS (CAPTURE ALS) is a Canadian platform designed to create the most comprehensive picture of people living with ALS with the objective of facilitating ALS research initiatives worldwide. The main aims of CAPTURE ALS include: (1) to characterize ALS and healthy controls with biosamples and data in order to provide the most comprehensive picture of individuals living with ALS to date; (2) to create a de-identified database and biosample repository linked to detailed clinical information; and (3) to develop and implement an inclusive and transparent participant engagement strategy to be active throughout all stages of CAPTURE ALS. CAPTURE ALS is a prospective, multicenter, observational, longitudinal study. People living with ALS, or a related disease and healthy controls undergo a harmonized protocol including the collection of detailed clinical information, neurological and cognitive examination, speech recording, advanced magnetic resonance imaging, and biosampling. Data and samples are stored in a biobank operating under an open science governance framework. An inclusive and transparent participant engagement strategy was designed and implemented throughout all stages of CAPTURE ALS. Four sites are operating in the consortium with a fifth being onboarded. The target enrollment is 120 affected participants and 50 controls, with the first participant visit having occurred in March 2022. Recruitment is ongoing. CAPTURE ALS is a scalable clinical research platform that connects scientists and patients to facilitate efficient translational research. The unique and deeply phenotyped data and biosamples are a global resource towards the development of biomarkers and understanding ALS biology. This study is registered at clinicaltrials.gov (NCT: NCT05204017).\n\nID: 41341425\nTitle: Exploring Speech Biosignatures for Traumatic Brain Injury and Neurodegeneration: Pilot Machine Learning Study.\nAbstract: Speech features are increasingly linked to neurodegenerative and mental health conditions, offering the potential for early detection and differentiation between disorders. As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health.\n\nID: 41283495\nTitle: Acoustic Vowel Metrics as Correlates of Dysphagia and Dysarthria in Brainstem Neurodegenerative Diseases.\nAbstract: Background/Objectives: Swallowing and speech rely on shared brainstem circuits coordinating oropharyngeal motor functions. In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (ρ = -0.660, p < 0.0001), FOIS (ρ = -0.531, p = 0.002), ASHA-NOMS (ρ = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (ρ = 0.538, p = 0.002) and PAS (ρ = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited.\n\nID: 41255457\nTitle: Early Multidisciplinary Rehabilitation Improves Swallowing and Speech Function in a Patient With Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a chronic, progressive neurodegenerative disease for which there is a lack of effective treatment. This case report describes a 49-year-old male with ALS who presented with dysphagia, dysarthria, dyskinesia, sleep disorders, anxiety, and depression. Following 45 days of early multidisciplinary rehabilitation, the patient demonstrated significant improvement in swallowing and speech function, alleviation of non-motor symptoms, and maintenance of motor function. Notably, he retained the ability to consume soft foods at a two-year follow-up. This case highlights the vital role of early multidisciplinary rehabilitation in the comprehensive management of ALS.\n\nID: 41205733\nTitle: Repurposing immunomodulatory drugs targeting microglia for amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder that progressively affects upper and lower motor neurons, leading to symptoms including dysarthria, muscle weakness, and paralysis. The disease is multifactorial, with a variety of contributing pathways, including excitotoxicity, oxidative stress, and neuroinflammation. Current treatments target only two of these pathways with limited efficacy, highlighting the need for alternative approaches. Increasing evidence highlights the involvement of immune dysregulation, particularly microglial-mediated neuroinflammation, in ALS pathology. Fortunately, many immunomodulatory drugs acting on microglia are already available for other diseases, indicating promising opportunities for drug repurposing. This literature review provides an overview of existing drugs under investigation for ALS, including those that have failed, and highlights microglia-targeting compounds with emerging repurposing potential. Compounds such as ibudilast, fingolimod, and modafinil have shown encouraging initial clinical results, whereas others were well-tolerated but underpowered or failed to demonstrate efficacy. New candidates, such as azithromycin, montelukast, doxycycline, tofacitinib, quercetin, belinostat, propranolol, and several kinase inhibitors, have demonstrated positive preclinical results, supporting their advancement toward clinical evaluation. Overall, these findings emphasize the potential of microglia-targeting therapies for ALS. To realize this potential, future studies must include larger cohorts, assess effects across different disease stages and patient subgroups, and examine sex differences. This is essential to address patient heterogeneity and improve personalized treatments for ALS patients.\n\nID: 41095520\nTitle: To Treat or Not to Treat: A Scoping Review of Speech Treatment for Dysarthria in Amyotrophic Lateral Sclerosis (ALS).\nAbstract: Speech loss is recognised as one of the most devastating outcomes for individuals with ALS, yet active speech intervention is rarely targeted in this population. Clinicians face significant challenges in managing dysarthria associated with ALS due to the rapidly progressive nature of the disease, historical concerns around intensive exercise accelerating decline, and an absence of direction on restorative and compensatory intervention strategies in current clinical care guidelines. This review evaluates the scope and quality of evidence for speech treatments in ALS to identify knowledge gaps and establish research priorities to guide clinical care. Studies were retrieved from six electronic databases (PubMed, CINAHL, Embase, Cochrane library, Web of Science, and PsycINFO). Four studies met inclusion criteria. Treatment approaches included: music-based speech therapy; multisubsystem speech rehabilitation program, tongue strengthening and articulation training; and Lee Silverman Voice Treatment-LOUD® combined with additional voice and articulation therapy. Sample sizes were small, with all studies demonstrating notable methodological weaknesses. The limited evidence base, marked by conflicting results and methodological flaws, prevents any reliable conclusions about treatment effectiveness. Despite the prevalence and impact of dysarthria in this population, evidence for speech treatment remains sparse, of generally low quality, and provides limited guidance for clinical practice. The changing perspective on exercise in ALS warrants rigorous investigation of tailored dysarthria interventions for this population that are minimally fatiguing and enhance speech by making use of residual physiologic support.\n\nID: 42429965\nTitle: Evaluation of Dysphagia in Patients with Obstructive Sleep Apnea: Diagnostic Patterns and Opportunities for Multidisciplinary Care.\nAbstract: To assess the frequency of dysphagia diagnosis in patients with OSA, characterize the use of clinical and instrumental swallowing evaluations, and identify gaps in care contributing to the underdiagnosis of unsafe swallowing in this population. Patients with OSA were identified using ICD-10 code G47.33 in the TriNetX Research Network, and those who had not undergone polysomnography were excluded. The prevalence of dysphagia (ICD-10 R13.1) and associated sequelae, including aspiration pneumonia (ICD-10 J69.0), was evaluated. Swallowing assessments were captured using CPT codes for clinical and instrumental evaluations. Of 1,328,355 patients with OSA, 15% had a documented diagnosis of dysphagia. The majority were coded with unspecified dysphagia (85%), followed by oropharyngeal dysphagia (21%). Sequelae of dysphagia, including aspiration pneumonia, malnutrition, and gastrotomy tube dependence, were seen in 19.1% of patients with both OSA and dysphagia. Despite this, only 29.56% of dysphagic patients underwent formal swallowing assessment. Specifically, 20.53% received a videofluoroscopic swallow study (VFSS) and 1.55% underwent flexible endoscopic evaluation of swallowing (FEES). Diagnostic yield varied by modality: 77.1% of patients undergoing instrumental evaluation were diagnosed with dysphagia, compared to 29.0% with clinical evaluation alone. Dysphagia is underrecognized in patients with OSA, with most diagnoses made without formal assessment despite substantial aspiration risk. Instrumental evaluations significantly improve diagnostic accuracy but remain underutilized. These findings highlight the need for standardized, multidisciplinary screening protocols to improve the detection and management of dysphagia in the OSA population.\n\nID: 42429793\nTitle: From Hate Speech to Justice Beliefs: A Serial Mediation Model Linking Victimization, School Climate, and Adolescents' Personal Belief in a Just World.\nAbstract: Victimization through hate speech represents identity-based violence during adolescence and is negatively related to core beliefs about justice. However, there is limited information on how exposure to hate speech leads to changes in an adolescent's Personal Belief in a Just World (PBJW). This study used the frameworks of Trauma Theory and Just World Theory to examine a serial mediation model in which victimization through hate speech was expected to lead indirectly to lower PBJW through perceived unsafety at school and decreased school well-being. A sample of 1,108 adolescents (Mage = 15.59; 61% female) in Italy completed self-report measures of victimization through hate speech, perceived school unsafety, school well-being, and PBJW. Results obtained using PROCESS Model 6 with 5,000 bootstrap samples indicated a significant indirect relationship: exposure to hate speech was associated with greater perceptions of unsafety in the school environment, which in turn were associated with lower levels of school well-being and lower PBJW. The direct effect of hate speech on PBJW was not significant, suggesting that the psychological impact of hate speech is primarily a result of how adolescents experience changes in their school environment on a daily basis. These results illustrate the cognitive pathway through which exposure to hate speech may contribute to adolescents' internalization of personal justice beliefs. This study advances understanding of the associations among hate speech victimization, school climate perceptions, and adolescents' personal beliefs about justice by identifying a theoretically derived pathway linking these constructs.\n\nID: 42429772\nTitle: Response to the Letters by Chang and Bernstein Ratner.\nAbstract: In our original article, we draw attention to the lifetime quality-of-life impairment that can result from childhood stuttering-hence, the need for immediate intervention after onset. We drew on existing experimental outcomes that parent speech-rate reduction and increased interturn speaker latency may reduce stuttering. We developed a two-factor treatment protocol based on those variables in combination and showed its clinical viability, suggesting that it would be a suitable target for Phase I-IV clinical trials. Chang and Bernstein Ratner wrote letters to the editor on our article, to which we respond. Our response to these letters to the editor covers the following issues raised by Chang and Bernstein Ratner: mechanisms of action for the proposed treatment, the evidence base for the treatment, plans to explore its treatment effects, and the need to verify its safety.\n\nID: 42429771\nTitle: Clarifying Neuroplasticity Claims in Parent-Led Early Stuttering Intervention: A Response to Onslow et al. (2026).\nAbstract: Onslow et al. propose a simplified, parent-led early intervention for childhood stuttering based on reductions in parental speech rate and increased interturn pausing, framed within a neuroplasticity rationale for early treatment. While the goal of developing scalable and accessible interventions is important, the conceptual link between these conversational modifications and neuroplastic recovery warrants clarification. Neuroimaging studies in childhood stuttering have identified neural differences associated with persistence and recovery, but these findings establish correlates of developmental change rather than evidence that specific parental behaviors causally induce circuit-level reorganization. Established principles of experience-dependent plasticity indicate that durable neural change in speech motor systems typically requires high repetition, task specificity, and performance-contingent engagement of relevant neural networks. Current evidence is lacking regarding the potential behavioral benefits of parent-mediated conversational modifications, and further research is required to demonstrate that such strategies can induce neuroplastic mechanisms underlying recovery from stuttering. Distinguishing between environmental modulation, short-term fluency facilitation, and neural causation is important to support mechanistic claims. I suggest that future research evaluate simplified parent-led interventions through adequately powered randomized trials and, where possible, incorporate longitudinal neural measures to determine whether behavioral improvements are associated with measurable changes in speech motor circuitry.\n\nID: 42429770\nTitle: Not So Simple, and Not So Fast: The Limits of Speech Rate and Turn-Taking Modifications for Treatment of Early Stuttering. A Response to Onslow et al. (2026).\nAbstract: We argue against suggestions for a new \"two-factor\" approach to early stuttering that counsels rate and turn-taking adjustments to child-directed parental speech. We find that (a) the suggested approach is not new; (b) the limited pilot data are directly contradicted by a much larger scale, longer duration study published in this journal this year that shows no relationships between rate and turn-taking and recovery from stuttering; (c) rate and turn-taking adjustments may bring with them additional negative changes in parental speech; and (d) the proposed treatment continues to emphasize the role of parents in determining recovery from stuttering, a belief with insufficient evidence and which carries potential harm.\n\nID: 42429768\nTitle: Cross-Linguistic Perspectives on Aging and Sentence Processing: The Role of Word Order and Semantic Plausibility.\nAbstract: This cross-linguistic study investigates how healthy aging affects sentence comprehension across three typologically distinct languages-English (head-initial), Korean, and Japanese (both head-final). It explores how syntactic word order and semantic plausibility interact with aging and whether these effects differ across languages with varying structural characteristics. A total of 290 adults participated: 103 English speakers (49 younger, 54 older), 98 Korean speakers (50 younger, 48 older), and 89 Japanese speakers (43 younger, 46 older). All participants completed a sentence-picture matching task using auditorily presented stimuli. The sentences were systematically manipulated for semantic plausibility (plausible vs. less plausible) and word order, contrasting instrument-first (instrument-theme) and theme-first (theme-instrument) structures. Aging effects were observed across all languages, with older adults performing worse than younger adults. Across language groups, participants showed better performance for instrument-first sentences than for theme-first sentences. Semantic plausibility interacted significantly with age across all languages in both accuracy and response times, indicating that older adults were disproportionately affected by reduced plausibility. In contrast, word order effects were largely similar across age groups, although a significant Age Group × Word Order interaction was observed in response times for the Japanese participants only. This study demonstrates that systematic manipulations of simple sentence structures can effectively expose age-related and cross-linguistic differences in sentence processing. The findings illuminate both universal patterns of cognitive aging and language-specific parsing mechanisms, informing the design of sensitive and typologically flexible tools for assessing cognitive-linguistic decline.\n\nID: 42429739\nTitle: Erratum to \"Temperament and Early Stuttering Development: Cross-Sectional Findings From a Community Cohort\".\nAbstract: \n\nID: 42429687\nTitle: Readability of Patient-Reported Outcome Measures in Adult Speech-Language Pathology Practice.\nAbstract: Patient-reported outcome measures (PROMs) are widely used in adult speech-language pathology to capture patient- and caregiver-perceived symptoms, functional impact, and treatment outcomes. For PROM data to be valid and equitable, end users must be able to comprehend and complete these instruments as intended. This study evaluated the readability of validated English-language PROMs used in adult speech-language pathology practice and examined variability across clinical domains. Seventy-four validated adult speech-language pathology PROMs spanning eight clinical domains were identified from a recent scoping review and supplementary searches. Patient-facing text, including instructions, item stems, and response options, was extracted and analyzed using four readability indices: Flesch-Kincaid Grade Level, Coleman-Liau Index, Simple Measure of Gobbledygook (SMOG), and FORCAST Grade Level (FORCAST). Readability estimates were summarized descriptively and compared against a ≤ 6.0 grade-level benchmark for patient-facing health materials. Across PROMs and domains, readability estimates frequently exceeded recommended grade-level thresholds. No PROM met the ≤ 6.0 benchmark across all four indices. When averaged across indices, only a small subset of PROMs, primarily within the language and voice domains, met recommended readability levels. Domain-level averages generally exceeded the benchmark, particularly when assessed using SMOG and FORCAST. Validated PROMs used in adult speech-language pathology practice often require reading abilities above recommended health literacy levels, potentially limiting independent completion and equitable use. Readability should be considered alongside psychometric properties during PROM development, selection, and implementation to support accessible and patient-centered assessment.\n\nID: 42429678\nTitle: From Foundations to Frontiers: Fit-for-Purpose Discourse Science.\nAbstract: This clinical focus article responds to discussions at the 2026 International Cognitive-Communication Disorders Conference (ICCDC), where participants highlighted a productive tension that has shaped discourse research for decades. Canonical discourse elicitation tasks (e.g., Cinderella retell) remain valuable because they support historical continuity, cross-study comparison, and shared data sets, yet they do not always capture the discourse constructs most relevant for all populations or clinical purposes. Discourse analysis has long been central to the assessment and treatment of neurogenic and cognitive-communication disorders, and canonical tasks have shaped decades of research by yielding replicable, analyzable, and linguistically rich language samples. This article is a narrative review that draws on the author's personal experience as a translational researcher and deep knowledge of the field. This article examines what canonical tasks revealed about language breakdown, why they succeeded within their original scope, where they may be inappropriate, and why and when they should still be retained. Building on discussion from the ICCDC, this piece argues that the field does not simply need \"new tasks\" but rather a principled framework for deciding when canonical tasks remain useful; when they should be adapted; and when new tasks, methods, and metrics are warranted. A fit-for-purpose discourse science is proposed, in which discourse tasks and outcome measures are selected because they are appropriate; robust; and aligned with the purpose, population, and construct of interest, while also integrating psychometric rigor, participatory design, and thoughtful use of technologies such as natural language processing and perceptual ratings. This clinical focus article also offers practical tables summarizing elicitation methods, suitable measures, key features of strong discourse assessment, clinically feasible implementation principles, and example scenarios for choosing canonical and noncanonical tasks in research and practice.\n\nID: 42429676\nTitle: A Survey of Speech-Language Pathologists' Current Clinical Practices in Setting Mastery Criteria.\nAbstract: Little is known about the mastery criteria that school-based speech-language pathologists (SLPs) select when writing therapeutic goals. This survey study aimed to document the criteria used, determine how data are collected by school-based SLPs, and examine the underlying reasons for the criteria used. This mixed-methods survey study recruited school-based SLPs in the United States via social media and e-mail to complete an online questionnaire of up to 16 items examining mastery criteria, data collection practices, and underlying rationales. Quantitative data were analyzed using descriptive statistics, and open-ended responses were analyzed using reflexive thematic analysis. One hundred twenty-five school-based SLPs completed the survey. The majority of respondents reported that they used a mastery criterion of 80% accuracy across three sessions. The most frequently cited reason was the belief that their chosen criteria would promote generalization and long-term retention. Trial-by-trial continuous data collection was the most common data collection method. Findings revealed a reliance on familiar mastery thresholds, despite emerging evidence supporting higher accuracy thresholds to promote skill maintenance and generalization. Some practices align with evidence, while others point to a need for better integration of empirical evidence into clinical decision making. https://doi.org/10.23641/asha.32677956.\n\nID: 42429652\nTitle: Parental Involvement, Gender Ideologies, and Socioeconomic Factors: Implications for Early Language Development in Preschool-Aged Children.\nAbstract: Research suggests that increased paternal involvement in childrearing has a positive effect on child development. However, there is a lack of knowledge about the role of fathers in their children's language development. The current study aimed to analyze the impact of parental involvement on language development of preschool children. It used a cross-sectional, correlational design to investigate the associations between parental involvement, particularly in language-promoting activities, and young children's language development, while also considering the role of parental gender ideologies and sociodemographic factors. Data were collected from 150 parents (fathers and mothers) and 80 children (average age of 47.35 ± 6.85 months), and two-family arrangements were compared. Parents completed extensive questionnaires, and children's linguistic skills were assessed using the European-Portuguese Preschool Language Assessment. The findings show that parental involvement, namely, reading to preschool children by both fathers and mothers, contributes significantly to their linguistic development, although in different ways. Parents with higher egalitarian gender ideologies tended to participate more actively in language stimulation activities. In addition, children from families with a more egalitarian division of parental tasks performed better in language development. Paternal and maternal involvement play a differentiating role in the language development of preschool children. These results reinforce the importance of promoting balanced parenting practices and programs that encourage the active participation of both parents from the early years of life, as well as the training of education and health care professionals, in order to value the role of the father in child development, contributing to richer contexts for child development.\n\nID: 42429600\nTitle: Prekindergarten and Kindergarten Predictors of Reading Comprehension in Monolingual English and Spanish-English Bilingual Sixth Graders.\nAbstract: Poor reading comprehension performance by children in the United States is a continuing concern. Early identification and intervention can reduce the number of children with significant reading problems. We documented prekindergarten and kindergarten predictors of Grade 6 reading comprehension for English monolingual and Spanish-English bilingual groups and identified measures available to educators to flag children at risk for future reading comprehension problems. In Grade 6, children in the monolingual (n = 88) and bilingual (n = 95) groups completed a reading comprehension measure. These children were in a longitudinal study with previously completed code-related, vocabulary, grammar, listening comprehension, higher level language, working memory, and nonverbal IQ measures in prekindergarten and kindergarten. Data were analyzed separately by language group. We fit a series of Bayesian mixed-effects models incorporating prekindergarten and kindergarten measures as predictors. For the monolingual group, the most promising prekindergarten predictor was letter identification, and the most promising kindergarten predictors were vocabulary, grammar/morphology, and listening comprehension. For the bilingual group, the most promising prekindergarten predictors were English vocabulary, listening comprehension in Spanish, and memory updating in Spanish, and the most promising kindergarten predictor was English vocabulary. We suggest measures that could be administered in prekindergarten and kindergarten to flag students who may be at risk for future reading comprehension problems. We review other steps that schools and families may take to prevent reading comprehension problems. https://doi.org/10.23641/asha.32885270.\n\nID: 42429443\nTitle: An Integrated Raman Platform with Embedded AI for Intraoperative Real-Time Cancer Detection.\nAbstract: Raman spectroscopy workflows are often fragmented across proprietary tools and ad hoc data-processing scripts, which slow decision-making and limit reproducibility and auditability. We present an integrated Raman platform with a Python-based GUI application that interfaces with the optical system(s) to unify instrument control, automate data acquisition, noise removal, signal processing, and run an embedded AI model for real-time classification of experimental samples. The system automatically archives intermediate and final outputs for auditability. We validated the platform's output for two types of experimental specimens: Tylenol and peritumoral biological samples from human laryngeal tissues. We compared the results with other studies, commercial software, and previous data-processing algorithms. The results obtained were consistent across all comparators. To demonstrate native analytics within the same workflow, we also developed and embedded a 1D convolutional neural network (CNN) tailored for biological Raman spectra. The multilayered CNN was trained on ex vivo human laryngeal tissue Raman spectra and was evaluated across 50 independent runs. The model achieved a mean test accuracy of 0.8929 ± 0.0213, a sensitivity of 0.9086 ± 0.0321, a specificity of 0.8698 ± 0.0434, and a mean AUC of 0.9506 ± 0.0142. The average latency across 50 runs was 2.82 s from signal acquisition to prediction, with device acquisition accounting for most of the time. The key innovation is not only the embedded AI but also an end-to-end, auditable workflow that unifies device control, acquisition, signal processing, visualization, and the archival of intermediate and final outputs, with optional real-time inference within a single platform.\n\nID: 42429356\nTitle: Infliximab for laryngopharyngeal involvement in Behçet's syndrome.\nAbstract: Laryngopharyngeal involvement in Behçet's syndrome is rare but clinically significant because it may cause severe odynophagia, dysphagia, and airway compromise. Optimal treatment has not been established, and irreversible structural sequelae, including laryngopharyngeal stenosis and ulcer scarring, may occur. We describe two men with Behçet's syndrome and symptomatic laryngopharyngeal involvement who showed rapid improvement after infliximab administration following an insufficient response to corticosteroids. In case 1, a 25-year-old man was classified as having suspected Behçet's syndrome based on recurrent oral ulcers, pharyngeal ulceration, arthritis, folliculitis-like skin lesions, and previous episodes of abdominal pain. He developed severe pharyngeal pain and dysphagia due to ulcerative lesions extending from the posterior pharyngeal wall to the esophageal inlet. Intravenous prednisolone resulted in limited endoscopic and symptomatic improvement, whereas infliximab promptly relieved pain and restored oral intake, with no recurrence over 14 years of follow-up. In case 2, a 29-year-old man presented with recurrent fever, oral aphthae, genital ulcers, arthritis, erythema nodosum-like lesions, and pharyngeal and laryngeal mucosal lesions associated with dysphagia. His symptoms and laryngoscopic abnormalities improved promptly after infliximab administration following an inadequate response to prednisolone. These cases underscore the importance of considering early anti-tumor necrosis factor-α therapy in steroid-refractory or relapsing laryngopharyngeal Behçet's syndrome, because progression to irreversible structural complications, including stenosis and adhesion, may necessitate surgical intervention if inflammation is not controlled before permanent damage occurs.\n\nID: 42429313\nTitle: Patient Perspectives on Self-Management of Voice Prostheses in Surgical Voice Restoration After Laryngectomy.\nAbstract: Surgical Voice Restoration is the gold standard method of re-establishing spoken communication after laryngectomy, where the voice-box is surgically removed. A silicone voice prosthesis (valve) allows voicing. To minimise health risks, valves must be changed swiftly if they fail. While self-management of health conditions is considered a key NHS objective, few people with laryngectomy in the UK change their own valve, requiring ongoing clinic attendance and healthcare professional input. To explore the perspectives of people with laryngectomy on self-changing, determining pertinent factors in decision-making around valve change methods with a view to informing clinical practice and supporting provision of personalised care. Ten semi-structured interviews were carried out online and via telephone. Five 'self-changers' and five participants using clinician-led valve changes were recruited via social media and charitable organisations. Reflexive Thematic Analysis was used to generate themes within the data. Thematic analysis generated three main themes. (1) My valve, my way; (2) Unequal relationships; (3) A search for normality. Data synthesis revealed patient perspectives on life with surgical voice restoration, which have otherwise not been explored in research to date. Valve leaks were associated with distress and linked to diminished social participation and quality of life. Barriers and facilitators to self-changing were highly individual, indicating the need for a personalised approach to education and decision-making around self-changing. Perceptions of disempowerment were expressed by people with laryngectomy, with limited opportunities for shared decision-making and an imbalance of power between patient and healthcare professional. Analysis also showed that self-changing may offer benefits by reducing the impact of valve changes on quality of life. Laryngectomy and surgical voice restoration have a significant impact on the activity and participation of people with laryngectomy. Empowering people with laryngectomy to participate in shared decision-making around their care is essential. A personalised approach is required, including the provision of tools, support and opportunity to jointly make decisions around valve change methods. Clinical implications include the core elements of decision-making conversations and training processes alongside points to consider for individual clinicians, service managers and policy makers. Further research on treatment burden and shared decision-making tools is warranted. What is already known on the subject Surgical voice restoration, using a silicone voice prosthesis (valve) to allow voice production, is considered the gold-standard in re-establishing communication after laryngectomy. The lifespan of each valve is finite, requiring swift replacement upon failure, to minimise health complications. Despite NHS objectives encouraging self-management of health conditions, a minority of people with laryngectomy learn to change their own valves; most remain reliant on healthcare professionals for valve changes. Little is known about the impact of this on daily life, as perspectives of people with laryngectomy have not been sought to date. What this paper adds to existing knowledge This study adds to the limited evidence-base around self-management in laryngectomy and represents the seldom-heard perspectives of people with laryngectomy on the consequences of surgical voice restoration on daily life. We report inequitable waiting times for valve changes and lack of confidence in out-of-hours care. We highlight pertinent factors in decision-making around valve change methods and reveal perceptions of disempowerment and restricted choice experienced by some people with laryngectomy who undergo surgical voice restoration. We raise queries over whether current practice meets multi-disciplinary recommendations around offering self-changing where appropriate. What are the potential or actual clinical implications of this work? This study demonstrates the need for a personalised approach to decision-making around valve management in surgical voice restoration. We recommend increased support and opportunity for shared decision-making in clinical practice and further research into the treatment burden of surgical voice restoration and the impact on quality of life after laryngectomy. Core elements of shared decision-making conversations and training processes pertinent to self-changing are discussed, with direct applicability to clinical contexts. Specific and actionable clinical implications are provided, relevant to individual clinicians, service managers and policy makers.\n\nID: 42429311\nTitle: Velopharyngeal Anatomy and Speech Production in Cleft Palate Surrounding Primary Palatoplasty: Protocol for a Prospective Observational Pilot Study.\nAbstract: Children with cleft palate often experience impaired speech due to atypical velopharyngeal anatomy following palate repair surgery. While surgical repair aims to restore the function of the palate, more than one-third of cases result in continued velopharyngeal insufficiency (VPI) and require reoperation, which can result in negative psychosocial impacts and financial burden. Common surgical approaches for primary palatoplasty, including intravelar veloplasty and double-opposing Z-plasty, have similar reported rates of VPI. Furthermore, procedure selection occurs without any presurgical imaging and varies by operating surgeon. Surgical decisions are often based on intraoperative judgment rather than objective measures. Structural and functional variables have been associated with speech outcomes in this population, but these data exist independently of one another until the school-age years, failing to establish a direct connection between anatomy and functionality of the velopharynx in toddlers. The current clinical paradigm misses a critical window of opportunity for earlier diagnosis of VPI. The purpose of this study is to (1) establish which presurgical anatomical variables are predictive of surgical procedure selection based on perceptual assessment of intraoperative tension for palate repair and (2) determine which postsurgical anatomical features are associated with the greatest diversity in oral stop consonant production at 18 months in children with a repaired cleft palate. A total of 30 infants with cleft palate will be recruited prior to palate repair. Within 2 weeks of repair, participants will undergo nonsedated magnetic resonance imaging (MRI) of the velopharynx and produce a home-based speech recording. Participants will complete the same protocol after palate repair at 18 months of age. Data will be analyzed by independent raters following completion of a training protocol. Anatomical dimensions of the velopharynx will be extracted from the MRI scans. The number and diversity of oral stop consonants will be extracted from the speech recordings. Interrater and intrarater reliability will be assessed. Logistic regression will be used to evaluate which presurgical anatomical measurements are predictive of surgical procedure selection. Analysis of covariance will be used to examine whether postsurgical anatomical measurements are associated with diversity of oral stop consonant production. This project was funded in August 2024. Data collection began in April 2025. As of April 4, 2026, a total of 8 participants had been enrolled, and data analysis had not begun. Results are anticipated in 2027. This study will use nonsedated MRI to investigate how velopharyngeal anatomy influences surgical decision-making and early speech outcomes. Such knowledge may be useful for presurgical planning and early monitoring of postsurgical speech outcomes in children with cleft palate.

There are no solid global epidemiological data on prevalence and incidence of NBIA subtypes, but registry data and expert opinion suggest PKAN, BPAN, PLAN, and MPAN are the most common subtypes. NBIA disorders present with a wide spectrum of clinical symptoms, including movement disorders (dystonia, parkinsonism, chorea), pyramidal involvement (eg, spasticity), speech and cognitive deficits, motor and cognitive slowing, and ocular abnormalities. Treatment remains symptomatic, though several new drugs are in development. Following our review published in 2021, this article provides an updated summary of recent developments. We discuss the rationale of new compounds, summarize clinical trials or-in their absence-preclinical studies for NBIA subtypes. The article is divided into two sections: one section on general approaches based on the shared feature of increased iron in the brain; and the second section on tailor-made, mechanistic treatments for the various NBIA subtypes targeting the specific molecular and cellular pathways of the affected enzyme including gene therapy. In summary, randomized controlled trials in NBIA have not yet demonstrated substantial benefit, neither for iron removal, in general, which appears to be clinically ineffective in most subtypes, except aceruloplasminemia; nor for subtype-specific approaches. Several ongoing studies are exploring more dedicated compounds in this exciting field.\n\nID: 42428865\nTitle: Free-Electron Laser-Based Extended Wide-Field Mid-Infrared Photothermal Imaging for Biomedical and Microplastic Analysis.\nAbstract: Wide-field mid-infrared photothermal (MIP) imaging offers rapid label-free chemical contrast for biomedical and polymer analysis. Its field of view (FOV) depends on the mid-infrared pump power of infrared lasers. Here, a wide-field MIP microscope is presented using up to 150 nJ pulse energies of a free-electron laser (FEL) as the pump source to achieve a larger FOV compared to a quantum cascade laser (QCL) excitation with typically 1 nJ pulses. Both implementations use counter-propagating beam paths with a microsecond pulsed 450 nm LED as the probe source and a CMOS camera that records images using a virtual lock-in detection scheme. FEL's higher pulse power expands the FOV by approximately a factor of 20, enabling submicron-resolution wide-field MIP imaging of polystyrene beads, single cells, and a murine brain tissue section. QCL systems with less intense pump pulses achieve only 45 μm FOV for samples including polystyrene beads, Mycobacterium tuberculosis-infected fixed tissue sections, and laryngeal cancer cryosections. IR spectra are reconstructed by tuning FEL and QCL wavelengths and collecting a series of wide-field images. We discuss current challenges and further improvements to implement high-power mid-IR pump lasers and shorter pulse probe sources for wide-field MIP imaging with even larger FOVs in the context of biomedical diagnostics and microplastic screening.\n\nID: 42428712\nTitle: An Unusual Cause of Ataxia in Patient with Sjogren's Syndrome: Metronidazole Neurotoxicity.\nAbstract: Cerebellar ataxia associated with metronidazole is rare. Sjögren's syndrome (SS), a chronic autoimmune disease, can also rarely present with neurological symptoms such as cerebellar ataxia. In this report, we aimed to present a 40-year-old female patient diagnosed with SS who developed acute-onset speech disorder and imbalance. The patient's complaints developed shortly, four days, after taking metronidazole for a vaginal infection. Her neurological examination revealed a broad-based gait, explosive speech, and bilateral dysmetria. Routine blood tests, nerve conduction studies, and cerebrospinal fluid analysis were normal. Brain magnetic resonance imaging showed hyperintensity in the dentate nuclei of the cerebellum, consistent with metronidazole-induced neurotoxicity. The patient's symptoms rapidly improved after discontinuation of the drug, and the lesions had completely resolved on imaging one month later. Apart from neuropathy and cerebellar degeneration, which are the most common etiologies of ataxia in Sjögren's syndrome, rare metronidazole-induced neurotoxicity was observed in our patient. Metronidazole-induced neurotoxicity may be a potentially reversible cause of cerebellar symptoms, and its recognition based on typical radiological features is important for drug withdrawal and complete recovery.\n\nID: 42428685\nTitle: Defining Frailty in Chinese-Language Biomedical Literature (2014-2024): A Decade of Conceptual Evolution.\nAbstract: Frailty is increasingly recognized as a central concept in aging research and clinical practice, which reflects reduced physiological reserve and heightened vulnerability to stressors. While extensively examined in Western biomedical literature, how frailty is defined and conceptualized in Chinese-language biomedical research remains insufficiently explored. This systematic review examined frailty definitions in Chinese biomedical publications from 2014 to 2024, analyzing definitional sources, conceptual emphases, and temporal trends. Searches across major Chinese and international databases identified 1804 eligible articles. Results show growing alignment with international frameworks, particularly through expert consensus statements, alongside improving terminological standardization. However, biomedical interpretations remain dominant, with limited attention to psychological, social, dynamic, and reversible dimensions. Emerging contributions from traditional Chinese medicine introduce distinct perspectives centred on balance and restoration. Clarifying these definitional patterns is essential for cross-cultural comparability and the development of culturally relevant frailty research and clinical practice.\n\nID: 42428597\nTitle: Massage Therapy for a Voice Student with Behavioral Dysphonia When Singing: A Case Report.\nAbstract: Behavioral dysphonia is a voice condition in which inefficient muscle tension and misuse interrupt the ability of the body to produce the desired vocal function and quality. Treatment methods typically incorporate traditional voice therapy with manual laryngeal manipulation. A lack of treatment approaches for dysphonia exists that address the vocal system including all its subsystems (i.e., breath, phonation, resonance, articulation) and posture. A limited number of reports exist describing the effect of massage therapy to address the vocal system anatomy of a singer with behavioral dysphonia. This case report explores the effects of a massage protocol targeting the vocal system of a person with symptoms of behavioral dysphonia when singing. A massage student completing an 8-month massage therapy program performed 90-min massage sessions twice a week for 3 weeks on a 33-year-old student singer/songwriter referred by his vocal instructor with symptoms of behavioral dysphonia. Symptoms presented only during singing and included \"tensing up,\" effortful voice, and vocal fatigue. Massage therapy sessions targeted the structure, musculature, and connective tissue of the whole vocal anatomy. Acoustic, aerodynamic, and physical outcomes were measured pre and post treatment. Baseline forward head posture, elevated shoulder position, cervical hyperlordosis, and thoracic hyperkyphosis, as well as thoracic/head/neck engagement during singing all decreased. Low laryngeal posture neutralized. Vocal range increased by six whole tones. Despite between-session variability, following the final session, loudness had increased by 6 dB, peak expiratory flow by 174 L/min, and inspiratory abdominal wall movement by 5 cm. Maximum phonation time improved within all sessions except on the final day. Functional measures for respiratory fluency, harmonics-to-noise ratio, and vocal range during singing all improved. Singing Voice Handicap Index improved by 9 points but remained below norms. A massage protocol addressing the whole vocal anatomy produced positive aerodynamic, acoustic, and physical outcomes in a person who presented with behavioral dysphonia when singing.\n\nID: 42428530\nTitle: Defining the Level of Need and Total Intervention Time in Children's Speech and Language Therapy in Finland: Developing a Consensus-Based Guideline.\nAbstract: Speech and language therapy is essential for supporting the skills and participation of children with disorders that impair their ability to interact, communicate, understand or use language, speak, eat or swallow. However, it might be challenging to outline how much intervention should be recommended for each individual. Currently, there are no guidelines to support clinical decision-making regarding the child's level of need for intervention, and thus, the recommended amount of speech and language therapy. The aim of the present work was to create a consensus-based guideline for clinical use in speech and language therapy in Finland to enhance equitable treatment and purposeful allocation of resources. This guideline was designed to assist in evaluating the child's level of need for intervention and, based on that, the total intervention time of speech and language therapy for children up to 17 years of age. A work group of Finnish speech and language therapists created a consensus-based guideline regarding the level of need for intervention and total intervention time during a 3-year process. During this time, the guideline was improved through a pilot phase following three comment rounds, including expert evaluations, conducted within the field of speech and language therapy as well as among other stakeholders. The ACCORD guideline was used to report this consensus work. A guideline including a framework for outlining the level of need for intervention was developed to support clinical decision-making regarding the total intervention time per year of speech and language therapy for children up to 17 years. The guideline is based on the International Classification of Functioning, Disability and Health and the idea of adaptive intervention. Four factors were considered essential: (1) impact the disorder has on participation, (2) need for consultative support, (3) severity of the disorder, and (4) expected benefit of the intervention. Application of the guideline in the Finnish context and expert evaluations on the guideline and its validity are presented. We developed a guideline to define the child's level of need for intervention and total intervention time. The content validity of the guideline was high based on the ratings by the expert evaluators. We hope that this guideline will support clinical decision-making regarding total intervention time per year in Finland and support the creation of similar guidelines in other contexts. The present guideline may facilitate both intradisciplinary and interdisciplinary discussion regarding the child's level of need for intervention, and based on that, the recommended total intervention time. Systematic considerations of predefined factors used to define the level of need for intervention may enhance more equitable national practices.\n\nID: 42428165\nTitle: Multifactorial determinants of complications and patient-reported outcomes in metal clasp-retained removable partial dentures.\nAbstract: This cross-sectional study aimed to evaluate the distribution of complications in clasp-retained removable partial dentures (C-RPDs) and to investigate the influence of denture design parameters, denture age, and Kennedy and Eichner classifications on complication patterns and patient-reported outcomes. 134 patients wearing 205 metal C-RPDs were included. Biological and mechanical complications were recorded. Denture design parameters (major connector type, clasp type and number, and rest number) were documented. Oral health-related quality of life Oral health-related quality of life (OHRQoL) and patient satisfaction were assessed using the OHIP-14 and a visual analog scale (VAS). Associations between complication patterns, design parameters, denture age, classifications and patient-reported outcomes were statistically analyzed. Mechanical complications were the most frequently observed complications. Mechanical complications and ulcerations were significantly associated with reduced OHRQoL. Denture age demonstrated a significant association with mechanical complications and patient-reported outcomes. Classifications showed limited associations with complications and did not influence patient-reported outcomes. Palatal plate and anteroposterior palatal strap designs were associated with physical pain and reduced speech satisfaction. In the mandible, dentures incorporating both circumferential and bar clasps demonstrated higher satisfaction, whereas the exclusive use of bar clasps was associated with increased physical disability. Higher numbers of rests and clasps were associated with lower overall OHIP-14 scores. Denture age and design characteristics were associated with complication patterns and patient-reported outcomes. Mechanical complications were more frequently observed in older dentures and, together with mucosal ulcerations, were associated with reduced OHRQoL. These findings suggest that individualized design strategies, regular follow-up, and timely maintenance may contribute to better mechanical stability and patient-centered outcomes in C-RPDs.\n\nID: 42428154\nTitle: Chorea as a Non-Thrombotic Manifestation in an Adolescent with Systemic Lupus Erythematosus, Antiphospholipid Syndrome and Heterozygous Prothrombin G20210A Gene Mutation: A Case Report.\nAbstract: Chorea is a rare movement disorder in the context of systemic lupus erythematosus (SLE). Although basal ganglia thrombosis, autoimmune injury or neuronal direct lesion have been proposed as possible explanations, its mechanism is still unknown. It is important to understand its pathogenesis so that the best treatments can be identified. A 12-year-old female adolescent with choreoathetoid movements of the trunk and four limbs, slurred speech, hypophonia and orofacial dyskinesia with 14 days of evolution. Brain magnetic resonance imaging revealed recent subcortical ischemic lesions in both frontal and parietal lobes. Basal ganglia lesions were not found. She started acetylsalicylic acid (ASA) and tetrabenazine, with chorea improvement. Transcranial Doppler ultrasound identified a microembolic sign between the left middle cerebral and anterior cerebral arteries. Therefore, ASA was switched to enoxaparin. Antinuclear antibodies and lupus anticoagulant (LAC) antibody were positive, with heterozygous prothrombin G20210A gene mutation being found. Five-day methylprednisolone pulses 1 g/day were performed, followed by prednisolone 60 mg/day. Intravenous immunoglobulin was administered, and hydroxychloroquine was initiated. Due to progressive microscopic hematuria and non-nephrotic proteinuria, a kidney biopsy was performed, being compatible with class V lupus nephritis. Consequently, mycophenolate mofetil and enalapril were started. Chorea resolved 5 days later. After discharge, LAC remained positive, but no more neurologic symptoms occurred. Basal ganglia thrombosis does not seem to be the most likely mechanism of SLE-related chorea. Antiphospholipid antibodies alone do not seem to be enough to trigger chorea. Further studies are needed to clarify the mechanisms that trigger this movement disorder.\n\nID: 42428047\nTitle: Linguistics and human brain: a perspective of computational neuroscience.\nAbstract: Elucidating the language-brain relationship requires bridging the methodological gap between linguistics' abstract theoretical frameworks and neuroscience's empirical neural data. As an interdisciplinary cornerstone, computational neuroscience formalizes language's hierarchical and dynamic structures into testable neural representation models through modeling, simulation, and data analysis, enabling computational dialogue between linguistic hypotheses and neural mechanisms. Recent advances in deep learning, particularly large language models (LLMs), have further advanced this inquiry: their high-dimensional representational spaces provide a new scale for probing the neural basis of linguistic processing, the model-brain alignment framework offers a principled approach to evaluating the biological plausibility of language-related theories, provided that representational correspondence is interpreted together with behavioral, temporal, causal, and biological constraints. This review synthesizes interdisciplinary progress from a computational neuroscience perspective. First, it outlines the core connotations of major linguistic frameworks (generative grammar, functional linguistics, and cognitive linguistics), their cross-cultural and evolutionary characteristics, and key challenges for neural alignment, including limited quantitative mechanisms, poor accessibility of abstract constructs to neural measures, and insufficient treatment of dynamics and plasticity. Second, it introduces the methodological foundations of linguistics-neuroscience dialogue, focusing on four technical pillars: neural activity measurement (e.g., fMRI, EEG, MEG, fNIRS, ECoG, SEEG), linguistic numerical representation, the evolution of language models from statistical approaches to LLMs, and neural coding frameworks that link model representations to brain signals, illustrated with a model-brain alignment case study. Third, it summarizes major findings, ranging from early computational insights into predictability and structural processing to recent LLM-driven progress in cross-modal interaction, inter-brain coupling, hierarchical computation, learning strategy sensitivity, and language plasticity. Finally, the review discusses current limitations-including functional alignment without structural homology, constraints on real-time validation, biased research coverage, and narrow evaluation metrics-and proposes future directions, such as exploring whether spiking neural network-based language models can improve biological plausibility in settings requiring temporally precise and event-driven neural modeling, developing cognitive-level alignment frameworks integrating memory, causality, and metacognition, and extending clinical applications. In summary, this work aims to advance a comprehensive, mechanistic understanding of the language-brain relationship and promote computational neuroscience as a generative theoretical framework for testable neuro-computational accounts of language.\n\nID: 42428043\nTitle: Speech-based depression detection using higher-order spectral features and a multi-level transformer.\nAbstract: A precise and prompt automated depression detection system utilizing auditory signals is essential, considering the scarcity of psychiatrists and the exorbitant expense of clinical diagnosis, resulting in approximately 60% of psychiatric patients globally lacking access to mental health care. This study proposes a Depression Detection model utilizing voice, which integrates hierarchical higher-order spectral distribution with deep learning models to overcome these issues. The utilized dataset is the Distress Analysis Interview Corpus, Wizard of Oz (DAIC-WOZ), comprising audio recordings of clinical interviews designed to facilitate the detection of psychological distress disorders such as depression, anxiety, and post-traumatic stress disorder. Two categories of features are extracted: statistical, handmade and bispectral features, as well as deep features utilizing the Multi-level Convolutional Transformer with attention learning (ML-CoT-AL) model. The ML-CoT-AL integrates the Convolutional Transformer (CoT), Channel and Element-wise Attention Module (CEAM), and Negotiator Modules (NM). The study presents the RIME optimization technique utilizing ML-CoT-AL for hyperparameter tuning, leading to improved accuracy in multi-level depression identification.\n\nID: 42427968\nTitle: Differential Cognitive Strategies for Speech-in-Noise Perception: A Comparative Study Between Yoga Practitioners and Non-practitioners.\nAbstract: Speech perception in noise varies widely even among normal-hearing individuals and is strongly influenced by cognitive factors such as attention, working memory and linguistic abilities. Yoga is known to enhance these domains, yet its potential impact on speech-in-noise perception remains insufficiently explored. This study investigated whether yoga practitioners (YP) demonstrate superior speech-perception-in-noise (SPIN) performance compared to non-practitioners and whether differences could be attributed to enhanced selective attention, working memory and linguistic processing capabilities. Sixty young adults (18-30 years) with normal hearing were recruited: 30 YP with a mean practice duration of 4.79 years and 30 non-yoga practitioners (NYP). Speech identification in noise was assessed using Kannada low-predictive sentences presented with speech babble and speech-shaped noise at varying signal-to-noise ratios. Cognitive measures included Stroop tasks (selective attention), digit span and N-back tests (working memory) and moving-average type-token ratio and generative naming (linguistic abilities). Scores were converted to rationalised arcsine units and group differences were analysed using independent t-tests and Mann-Whitney U tests. Stepwise linear regression identified predictors of SPIN performance. YP demonstrated significantly superior performance in speech babble at 0 dBSNR (p = .009) but not in speech-shaped noise conditions. Regression analyses revealed distinct predictive patterns: vocabulary (generative naming) predicted 26% of variance in NYP (β = 0.534, p = .002), while working memory (backward digit span) predicted 11.6% of variance in YP (β = 0.383, p = .037). Cognitive and linguistic measures showed no significant group differences. YP exhibited superior speech identification under informational masking conditions, mediated by working memory capacity. Our findings suggest that yoga practice is associated with a shift from vocabulary-based to working memory-based strategies for speech-in-noise perception.\n\nID: 42427919\nTitle: 3D Electrical Impedance Tomography of Regional Ventilation During Jet Ventilation: A Pilot Study.\nAbstract: Low-frequency jet ventilation (LFJV) is commonly used in laryngotracheal surgery when intubation is not feasible. However, limited understanding of regional ventilation and distal airway pressures raises safety concerns and restricts broader adoption. This study employed electrical impedance tomography (EIT) to quantify tidal volumes and regional ventilation patterns in patients undergoing airway surgery with LFJV. Adult patients undergoing microlaryngeal surgery for subglottic stenosis were prospectively recruited from the Laryngology Clinic. A standardized anesthesia protocol was followed. EIT was used to measure tidal volumes and assess regional ventilation during bag-mask ventilation, laryngeal mask airway (LMA) ventilation, LFJV before and after dilation, and during recovery. Linear mixed-effects models were applied to compare LFJV with LMA ventilation, accounting for repeated measures within subjects. Six patients underwent surgery with EIT monitoring, of whom four had complete datasets for analysis. LFJV preferentially ventilated apical lung regions, while basal regions were consistently under-ventilated. Apical-to-basal volume ratios were consistently higher during LFJV compared with LMA (> 100% higher). Similar differences were observed in the global inhomogeneity index (24% higher), left-to-right ratio (21% higher), and anterior-to-posterior ratio (9.5% higher). This is the first study to apply EIT to assess ventilation distribution during LFJV for microlaryngeal surgery. LFJV was associated with relative hypoventilation of basal and dorsal lung regions and increased ventilation inhomogeneity compared with LMA ventilation. Larger studies are warranted to validate these results and inform optimization of LFJV in clinical practice. 4.\n\nID: 42427757\nTitle: The human language processing system straightens natural speech.\nAbstract: Large language models trained on next-word prediction have impressive linguistic capabilities. This suggests that the goal of temporal prediction is essential to language processing, but how this goal impacts the structure of speech representations in the human brain remains unknown. Here, we test the hypothesis that prediction is facilitated by the temporal straightening of representational trajectories along the speech processing hierarchy. We developed a methodology for measuring the curvature of these trajectories using fMRI. Our method exploits a previously unknown connection between the timescale of single-unit responses and the curvature of population trajectories. We examined brain responses of subjects listening to natural speech. Response trajectories were most curved in lower-level auditory areas and progressively straightened along the cortical hierarchy. We presented the same speech stimuli and perturbed versions thereof to wavLM-a speech representation model that is well aligned with human brain responses-and found that hierarchical straightening effects are strongest for stimuli whose statistical structure resembles natural speech. Together, our results establish a direct connection between the goal of temporal prediction, the geometry of neural speech representations, and the cortical hierarchy of representational timescales.\n\nID: 42427691\nTitle: Within-electrode temporal envelope processing predicts multi-channel speech outcomes across cochlear implant pulse rates.\nAbstract: Cochlear implants (CIs) restore hearing by stimulating auditory neurons to encode amplitude envelopes across frequency bands, providing essential cues for speech recognition. This study investigated how stimulation pulse rate constrains temporal envelope processing and speech cue perception in ten post-lingually deaf CI users by evaluating amplitude modulation (AM) detection thresholds and consonant identification performance across pulse rates. The effects of pulse rate on temporal processing and speech perception were examined using both standard clinical multi-channel strategies and single-channel strategies designed to isolate within-channel envelope representations. Results revealed a significant decline in AM detection and consonant recognition performance at the lowest tested pulse rate of 125 pulses per second (pps), consistent with perceptual constraints on temporal processing at low carrier rates, rather than inadequate envelope sampling. At the highest pulse rate of 4000pps, a non-significant reduction in AM detection was observed which may be consistent with previously reported reductions in amplitude discrimination at high pulse rates. Consonant recognition performance remained stable across clinically relevant pulse rates (250-2000pps), though listener-specific pulse rate effects were observed. Notably, significant correlations were found between single-channel and multi-channel performance in AM detection and consonant recognition tasks. These findings support an important contribution of within-electrode temporal envelope processing to multi-channel speech perception and highlight the clinical relevance of individual variability in pulse rate effects.\n\nID: 42214970\nTitle: The beat in speech: A window into the attentional mechanisms supporting the detection of non-adjacent dependencies.\nAbstract: Converging evidence suggests that musical training can elicit positive transfer effects across multiple domains of language processing, including grammar. In humans, exposure to musical rhythm induces beat and meter perception, which has been shown to enhance attentional allocation and temporal prediction. Theories hypothesize that the predictive gains intrinsic to music rhythmicity may exert cascading effects on syntactic processing by modulating sensitivity to speech prosody. From this perspective, learning should also be boosted insofar as prosody tends to align with grammatical structure. In the present study, we introduce a novel behavioural paradigm to investigate the link between rhythmicity and grammar learning by testing whether the rhythmic beat facilitates the detection of grammar-like structures in artificial languages (ALs), implemented as non-adjacent dependencies (NADs) between variable syllables forming a speech stream (e.g., PU reliably predicts KI in PUlaruKI). A total of 147 participants were exposed to four ALs that varied in rhythmic, grammatical structure, and the alignment between the two: (i) a beat-inducing rhythm with no NADs; (ii) a beat-hindering rhythm with NADs; (iii) a beat-inducing rhythm with embedded NADs temporally misaligned, and (iv) NADs aligned with beat time-points. Results of the implicit and, after exposure, explicit learning measures demonstrate enhanced learning when NADs are embedded within beat-inducing rhythmic structures. Together, these findings suggest that rhythm enhances predictive and attentional mechanisms implicated in grammar learning, underscoring their role in its acquisition.\n\nID: 41925483\nTitle: Neuroimaging confirms selective cerebral involvement in primary lateral sclerosis and predilection to brain regions with high metabolic activity.\nAbstract: Primary lateral sclerosis (PLS) is a low incidence motor neuron disease manifesting in progressive limb spasticity, gait impairment, bulbar dysfunction and often in pseudobulbar affect. Varying degree of frontotemporal involvement has also been recently confirmed. Postmortem data is scarce in PLS and disease burden patterns are best characterised in vivo by purpose-designed neuroimaging protocols. A large prospective neuroimaging study has been undertaken to explore cerebral involvement patterns in PLS using a both structural T1-weighted data and diffusion MRI data. Neuroimaging data were complemented by genetic screening and comprehensive clinical profiling. Brain involvement patterns have been first characterised by standard morphometric and diffusivity analyses. Resulting disease burden maps were then correlated to physiological mitochondrial density (MitoD) maps. In an additional, region-of-interest analysis, brain regions with significant topological associations between neurodegeneration and MitoD were ranked based on their r-values. Grey matter degeneration in PLS is not limited to the motor cortex, but also encompasses frontotemporal, caudate, thalamic, cerebellar and cingulate regions. Voxelwise statistics confirm topological associations between atrophy and physiological mitochondrial density. The most significant associations between neurodegeneration and MitoD were detected in the cerebellum, superior temporal lobe, precentral gyrus, inferior operculum, and orbitofrontal gyrus. Similarly, white matter degeneration is not limited to the corticospinal tracts, but includes the corpus callosum, frontotemporal association fibres, the cingulum, cerebellar peduncles, and the fornix. Anatomical associations were also detected between diffusivity alterations and focal MitoD. PLS is associated with a selective disease burden pattern, and our data suggest that brain regions with high baseline metabolic activity are more likely to succumb to neurodegeneration. Cerebral areas showing the most significant anatomical associations between atrophy and mitochondrial density (precentral gyrus, cerebellum, frontotemporal regions) are pathognomonic brain regions of PLS driving its core clinical manifestations.\n\nID: 41718496\nTitle: Timing of communication and technology control support in ALS - a systematic review.\nAbstract: Objective: To review evidence on the optimal timing of interventions that support communication and technology control for people living with Amyotrophic Lateral sclerosis (ALS). Methods: A systematic review was conducted following a pre-registered protocol. Databases were searched for studies involving people living with ALS that addressed timing of assistive technology interventions for communication or technology control. Screening and data extraction were completed in duplicate, findings were synthesized using a thematic analysis, and relevant findings presented as a descriptive summary. Results: Twenty-eight studies met the inclusion criteria. Evidence focused overwhelmingly on communication support rather than wider assistive technology interventions. Need for a communication aid typically occurs between one and five years from diagnosis and the timing of this varies significantly according to the site of onset of ALS. There are significant variations in the timing of changes for individuals within these groupings and there are likely a larger number of groupings that would be clinically useful. A significant correlation between changes in speaking rate and intelligibility has been shown. Once changes to speech do start to occur then the time to the loss of functional speech appears relatively consistent across the types of ALS. Conclusion: Current best practice guidelines are not reflective of the findings of this review and do not support professionals in identifying how to provide timely support. Monitoring speech changes systematically may support timely intervention. There is potential for individual level predictive modeling to help support people living with ALS to be proactive and prepared for changes.\n\nID: 41685589\nTitle: Cognitive Dysfunction Is Associated With an Underestimation of Respiratory Function in ALS.\nAbstract: The association between low forced vital capacity (FVC) and cognitive impairment in ALS is ambiguous; it could be due to respiratory dysfunction and/or poor effort from cognitive deficits. We used the objective, non-volitional phrenic nerve motor response amplitude (PAmp) to clarify how cognitive status affects the relationship between diaphragmatic strength and FVC. This retrospective study included 73 patients with ALS followed in our clinic. FVC and PAmp were measured, and cognitive status was assessed with the Edinburgh Cognitive and Behavioral ALS Screen (ECAS). Regression models tested for associations between FVC and distinct ECAS domains and whether these domains influenced the PAmp-FVC relationship. PAmp (β = 0.58, p = 0.001) and its interaction with an abnormal ECAS's Executive score (β = -0.20, p < 0.045) were significant predictors of FVC. The latter indicated that patients with abnormal executive function had lower FVC than cognitively normal patients at similar PAmp values. Moreover, in patients with abnormal executive function, a reduction in PAmp was associated with a shallower decline in FVC. Severe bulbar dysfunction was also negatively associated with FVC (β = -0.22, p = 0.024). FVC may underestimate respiratory capacity in cognitively impaired patients; therefore, we recommend non-volitional measures when evaluating ALS patients with executive dysfunction.\n\nID: 41199620\nTitle: Acoustic Features in ALS: Taking a Pause to Appreciate a Novel Remote Respiratory Monitoring Strategy.\nAbstract: \n\nID: 41164053\nTitle: Clinical Reasoning and Diagnostic Challenge in a 23-Year-Old Man With Rapidly Progressive Dysphagia and Hypophonia: Juvenile-Onset Amyotrophic Lateral Sclerosis Caused by a FUS Gene Mutation.\nAbstract: Dysphagia and dysphonia of unclear etiology in young adults pose a significant diagnostic challenge, as these symptoms are more commonly attributed to benign or structural causes rather than serious neurodegenerative disease. The absence of classic neuromuscular signs such as limb weakness, hyperreflexia, or fasciculations can delay consideration of motor neuron disease, particularly when bulbar symptoms occur in isolation. We describe a previously healthy 23-year-old man who presented with rapidly progressive dysphagia and hypophonia, initially misattributed to infectious causes. Despite an extensive workup for structural, autoimmune, and infectious causes, no clear etiology was identified. Neurologic examination revealed predominantly bulbar dysfunction, and electrodiagnostic studies showed acute to subacute denervation changes in the tongue and trapezius muscles. Genetic testing confirmed juvenile-onset amyotrophic lateral sclerosis due to a pathogenic FUS gene mutation (p.Pro525Leu). This case highlights the importance of including motor neuron disease in the differential diagnosis of rapidly progressive bulbar symptoms of unknown origin. It highlights the importance of early electrodiagnostic testing and genetic evaluation in establishing a diagnosis.\n\nID: 41149102\nTitle: Oral Health Status in Patients with Amyotrophic Lateral Sclerosis: A Scoping Review.\nAbstract: Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative syndrome which often leads to progressive muscular dysfunction and therefore oral health deterioration. The aim of this scoping review is to evaluate oral health status in ALS patients focusing on the importance of dental care in improving patient's quality of life. Methods: A comprehensive literature search was conducted on PubMed, Scopus, Web of Science, and Embase databases until June 2025 using a combination of keywords and MeSH terms related to ALS and oral health. Studies were screened and selected based on inclusion and exclusion criteria, focusing on human clinical data reporting oral health outcomes in ALS. Results: Eight studies met the inclusion criteria. The findings showed a high prevalence of oral complications in bulbar-onset ALS patients. Common issues included reduced tongue mobility, poor oral hygiene, sialorrhea, and decreased masticatory function were evaluated. Conclusions: Oral health impairment in ALS patients frequently contributes to systemic risks and reduced quality of life. A dental expert may play an important role in multidisciplinary care teams in terms of early diagnosis and conservative treatment of oral diseases ranging from periodontal disease to temporomandibular disorders (TMD). Personalized oral hygiene strategies and adjunctive therapies may serve as key elements in maintaining overall health and patient comfort in ALS. Therefore, the objective of the following review was to evaluate oral health complication in patients with ALS, highlighting the impact of oral care on patients' quality of life.\n\nID: 41082679\nTitle: International Survey of Practice Patterns of Speech-Language Pathologists Working With Patients With Amyotrophic Lateral Sclerosis.\nAbstract: Speech-language pathologists (SLPs) evaluate and treat swallowing and communication impairments in individuals with amyotrophic lateral sclerosis (ALS). Standardized clinical practice guidelines for the evaluation and management of bulbar dysfunction in ALS have not yet been established. This study aimed to describe current international practice patterns of SLPs evaluating and treating bulbar dysfunction in ALS. Significant variability in practice patterns will exist across SLPs working in different clinical settings with varied resources. A 26-item Qualtrics survey was electronically distributed to SLPs via e-mail, social media, and professional discussion boards. Data from 245 respondents across 20 countries and 32 states within the United States were collected, with the final analysis including 214 respondents. Most respondents practiced in metropolitan areas (69%) and worked in multidisciplinary ALS clinics (41%), outpatient clinics (16%), and home health settings (17%). Cranial nerve examination (91%), swallow trials (79%), speech intelligibility tasks (85%), and diadochokinetic speech rates (65%) were frequently included in evaluations. Although 81% of clinics had access to instrumental swallowing evaluations, 32% reported performing them in fewer than 25% of patients. Communication evaluations were offered directly by 58% of clinicians, while 26% referred to an outside SLP and 16% collaborated with device representatives. Most clinicians provided patient education on swallowing (87%) and oral health (83%). However, managed practice varied widely, revealing no standardized treatment that is routinely offered. Barriers to optimal ALS care included time constraints, relevant clinical training, timing of treatment, addressing psychosocial components of care, access to resources, interdisciplinary communication, and insurance coverage (United States only). Findings reveal little consensus on symptomatic bulbar management and intervention timing. Results emphasize the urgent need for the development of a standardized minimal data set to best guide the evaluation and management of bulbar dysfunction in ALS. https://doi.org/10.23641/asha.30249997.\n\nID: 41004918\nTitle: Tongue shear wave elastography for bulbar dysfunction in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) often manifests with tongue involvement, leading to dysarthria and dysphagia. While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ® E9, 9 MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80 kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48 kPa, range 8.50-21.42) and controls (14.16 kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p < 0.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS.\n\nID: 41004400\nTitle: Atypical features including acquired oculomotor apraxia in C9orf72-associated familial primary lateral sclerosis.\nAbstract: The phenotypic variability of C9orf72-associated disease is broadening, including atypical and non-motor presentations. C9orf72-associated neurodegeneration has only rarely been associated with primary lateral sclerosis (PLS), and even more rarely with ocular motor apraxia. Describe a family with C9orf72 mutation presenting with frontotemporal dementia (FTD) and atypical PLS phenotypes and discuss the implications regarding 1) where PLS lies on the ALS-FTD spectrum, and 2) how C9orf72 mutations influence PLS clinically. Chart review. A 52-year-old male experiencing 4 months of progressive right lower leg spasticity with a family history of FTD was referred to us. Within 15 months, he was anarthric and required a powered wheelchair. He developed acquired ocular motor apraxia, consistent with supranuclear ophthalmoplegia. He later developed laryngeal dystonia which led to his death. Ten years later, his 67-year-old brother presented with 8 months of progressive spastic dysarthria, hyperreflexia, right foot drop, and right facial weakness. Genetic testing revealed heterozygous C9orf72 hexanucleotide repeat expansion. This family's presentation expands on sparse reports of C9orf72-associated PLS. The proband showcases a severity of ocular motor deficits not yet reported in PLS, extending ocular motor findings in MND. These deficits also provide clinical evidence of degeneration outside the motor cortex/spinal cord in PLS. The symptomatology (laryngeal dystonia, rapid progression) clinically overlaps with ALS/FTD, suggesting PLS may lie on the ALS-FTD spectrum. The severity and atypicality of this case also support suggestions that C9orf72 mutations amplify the spectrum/severity of disease observed in TDP-43 proteinopathies.\n\nID: 40851280\nTitle: Automatically measured speech intelligibility models bulbar-specific disease severity and progression in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to widespread motor deterioration, including significant motor speech impairments. Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments. Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments.\n\nID: 40808712\nTitle: Acoustic signatures of bulbar ALS: Predictive modeling with sustained vowels and LightGBM.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a degenerative neurologic disease with no definitive biomarkers for early detection. This paper discusses the use of acoustic analysis of sustained vowel phonations (SVP) and machine learning in ALS detection. An SVP corpus of 128 (64 /a/ and 64 /i/) from 31 patients with ALS and 33 healthy controls (HC) was employed. 131 acoustic features, including jitter, shimmer, Mel-Frequency Cepstral Coefficients (MFCCs), and Pathological Vibrato Index (PVI), were extracted. A LightGBM (Light Gradient Boosting Machine)-based model was built and optimized using 5-fold cross-validation to separate ALS cases. Model performance and feature importance were evaluated. The model performed well with high predictability, yielding an RMSLE of 0.162 and most predictions closely correlating with actual diagnoses. The top features obtained were S55_i, CCI(2), and dCCa(12), which were consistently at the top of the ranking list, indicating their role in ALS detection. The PVI was determined to be a significant biomarker with high values having high correlations with ALS diagnoses. But the multimodal nature of the predictive values indicated some flaws in generalization. This paper demonstrates the applicability of acoustic analysis and machine learning for early ALS detection. The proposed method provides an affordable, low-cost, and non-invasive way for ALS diagnosis with potential for application in telemedicine and clinical settings. Future research must expand datasets and integrate additional diagnostic modalities to improve the model's robustness and clinical translation.\n\nID: 40726766\nTitle: Listener effort measures clinically meaningful change of dysarthria in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative motor neuron disease that can cause progressive bulbar dysfunction and dysarthria, resulting in reduced quality of life. Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36). The LE prediction model predicted the true LE, with an average R 2 of 0.83 ± 0.07. Dysarthria is associated with decreased quality of life in people with ALS. Quantitative measures of dysarthria in ALS could be useful as ALS clinical trial outcome measures, providing insight into the progression of bulbar symptoms. Speaking rate quantifies progression but is variable across speaking stimuli, emotional states and contextual factors. LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials. Furthermore, a LE prediction model is effective at predicting LE scores and should be validated on an external dataset.\n\nID: 40673749\nTitle: An Explanatory Model of Speech Communication Centered on Multiscale Rhythmic Modulation: Implications for Motor Speech Assessment and Intervention for Individuals With Amyotrophic Lateral Sclerosis.\nAbstract: This study proposed an explanatory model of speech communication centered on multiscale rhythmic modulation to inform motor speech assessment and management. To these ends, a fit-for-purpose, automated measurement tool was used to evaluate and/or cross-validate (a) the previously reported effect of a neuromotor disorder-amyotrophic lateral sclerosis (ALS)-and (b) the effects of two cueing strategies, commonly used in managing motor speech disorders, on rhythmic modulation of speech. A secondary analysis was carried out on the X-ray Microbeam database. The analyzed data included the articulatory-kinematic and acoustic recordings of a phonetically loaded sentence produced by 19 individuals with ALS and 23 neurologically healthy controls in one habitual style and two nonhabitual styles as elicited by the slow and clear speech cues, respectively. The measurement tool quantified the modulation patterns of four articulators as well as four critical-band and one wide-band envelopes at three linguistically relevant timescales (delta, theta, beta/gamma) to assess rhythm control at the prosodic, syllabic, and subsyllabic levels. To address the research aims, the disease and speaking style effects on all modulation metrics were evaluated. For Aim 1, speakers with ALS showed reduced modulation depth of multiple articulators and critical-band envelopes at all timescales. For Aim 2, the slow speech cue elicited changes in articulatory modulation at multiple timescales, globally enhancing the control of all and especially syllabic and subsyllabic rhythms in speakers with ALS. Clear speech primarily elicited changes in articulatory modulation at the theta timescale, generating a more restricted effect on syllabic rhythm. The findings generally aligned with our prior research, supporting the robust utility of the measurement tool for assessing rhythmic disturbances of speakers with ALS. Moreover, this tool showed promise for delineating cueing-elicited changes in rhythmic modulation of speech, which has potential implications in tailoring and evaluating the outcomes of behavioral intervention.\n\nID: 40571609\nTitle: Can Language Characteristics Contribute to the Classification of Neurodegenerative Disorders? -An Exploratory Study.\nAbstract: Objective Evaluating language symptoms is challenging owing to their varied presentations. We developed a Japanese Language Screen (JLS) to assess 11 language aspects, including agrammatism, impairment of articulation and prosody (IAP), word recall, syntactic comprehension, meaning of proverbs, and writing, considering the unique features of the Japanese language. Methods Using the JLS, we assessed the language functions in patients with Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and healthy controls (HC) to identify language symptoms specific to each condition and determine whether the JLS can differentiate between diseases and HC. Results The study included 168 participants. The total JLS score categorized the participants' language status as normal or impaired. According to the total score, PSP patients had more severe language deficits than AD patients, despite comparable cognitive scores. Substantial differences were found in the 11 assessed items for each disease. Patients with AD and PSP showed decreased performance in more than half of the items compared to HC, with the PSP group being more impaired. ALS patients showed decreases in IAP and writing, notably in the meaning of proverbs, whereas PD was closely comparable to HC. Conclusion This study suggests that while the JLS is useful for understanding the language symptoms associated with neurodegenerative disorders, its ability to classify them remains limited.\n\nID: 40540830\nTitle: Pick's disease presenting as progressive apraxia of speech: Atypical clinical and neuroimaging features in three autopsy-confirmed cases.\nAbstract: Patients with progressive apraxia of speech (PAOS) often develop atypical parkinsonian features suggestive of corticobasal syndrome (CBS) or progressive supranuclear palsy (PSP), and typically have an underlying 4-repeat tauopathy at autopsy. We describe three cases of PAOS with underlying Pick's disease, a 3-repeat tauopathy, who lacked CBS or PSP features during life. We reviewed patients enrolled in the Neurodegenerative Research Group's ongoing studies on speech and language disorders and identified those with PAOS who had autopsy-confirmed Pick's disease. All patients had comprehensive neurologic, speech-language, and neuropsychological assessments, as well as multimodal neuroimaging, during life. Three female patients presented with phonetic PAOS without parkinsonism. Patient 1 had speech onset at age 54, later developed behavioral variant frontotemporal dementia (bvFTD), and died at 64. Patient 2 had speech onset at 47, early bvFTD features, prominent frontal and temporal involvement, and died at 53. Patient 3 had speech onset at 58, minimal behavioral changes, primarily frontal involvement on imaging, and died at 63. Our findings highlight that Pick's disease can present with PAOS and may be distinguished from 4R-tau PAOS by an absence of motoric CBS/PSP features and, in some cases, by prominent temporal hypometabolism with bvFTD development. These atypical features may prove useful in the antemortem identification of Pick's disease as a cause of PAOS.\n\nID: 40506548\nTitle: An instantaneous voice-synthesis neuroprosthesis.\nAbstract: Brain-computer interfaces (BCIs) have the potential to restore communication for people who have lost the ability to speak owing to a neurological disease or injury. BCIs have been used to translate the neural correlates of attempted speech into text1-3. However, text communication fails to capture the nuances of human speech, such as prosody and immediately hearing one's own voice. Here we demonstrate a brain-to-voice neuroprosthesis that instantaneously synthesizes voice with closed-loop audio feedback by decoding neural activity from 256 microelectrodes implanted into the ventral precentral gyrus of a man with amyotrophic lateral sclerosis and severe dysarthria. We overcame the challenge of lacking ground-truth speech for training the neural decoder and were able to accurately synthesize his voice. Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies. These results demonstrate the feasibility of enabling people with paralysis to speak intelligibly and expressively through a BCI.\n\nID: 40466410\nTitle: [Use of tongue pressure to determine the indication for instrumental swallowing assessment in patients with spinal ALS].\nAbstract: Systematic swallowing assessment in amyotrophic lateral sclerosis (ALS) is essential, as approximately 85% of patients will develop dysphagia, and 8% of these cases may remain clinically silent. Although instrumental diagnostic tools exist, they are not always accessible. Recent studies suggest that lingual pressure measurements may be valuable for early detection of bulbar dysfunction. This study aims to establish lingual pressure cutoff points for early screening of such dysfunction. Transversal study based on prospectively collected data from patients with spinal-onset ALS at the Motor Neuron Unit, Hospital del Mar (Barcelona). A total of 58 patients were included. Anterior (PA) and posterior (PP) lingual pressures were measured using the IOPI system and analyzed alongside the ALSFRS-R scale. Statistical analysis included descriptive statistics, Spearman correlation, and ROC curve analysis (SPSS v25). A moderate correlation was found between lingual strength and ALSFRS-R scores (PA: r=.634, P<.001; PP: r=.539, P<.001). Identified cutoff values: PA: 39.5kPa (AUC=.766; 95%CI: .700-.831; P<.001), sensitivity 64.6%, specificity 76.4%. PP: 37.0kPa (AUC=.726; 95%CI: .653-.799; P<.001), sensitivity 55.1%, specificity 72.2%. In spinal-onset ALS, a moderate correlation exists between global functionality and lingual pressures. Cutoff points of PA=39.5kPa and PP=37.0kPa are proposed for early screening of bulbar dysfunction.\n\nID: 40460399\nTitle: Construct Validity of the Amyotrophic Lateral Sclerosis Bulbar Dysfunction Index-Remote.\nAbstract: The Amyotrophic Lateral Sclerosis Bulbar Dysfunction Index-Remote (ALSBDI-R) is a clinician-administered tool designed to assess bulbar dysfunction remotely in patients with amyotrophic lateral sclerosis (ALS). This study aimed to evaluate the construct validity of the ALSBDI-R by examining its correlation with established clinical measures and its ability to discriminate among different bulbar disease severities. A total of 92 patients with ALS were recruited from two multidisciplinary clinics. Participants were assessed using the ALSBDI-R, the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R), the Center for Neurologic Study Bulbar Function Scale (CNS-BFS), the Sentence Intelligibility Test, and the Eating Assessment Tool (EAT-10). Construct validity was established through Spearman correlations and comparison of ALSBDI-R scores across bulbar severity groups (asymptomatic, mild, moderate, severe). Strong correlations were found between ALSBDI-R total scores and bulbar-specific measures such as ALSFRS-R bulbar subscore (r = -.85), CNS-BFS (r = .85), and EAT-10 (r = .77). The ALSBDI-R effectively discriminated between severity groups, supporting its construct validity. Severity bins were created based on median ALSBDI-R total scores for each group. The ALSBDI-R is a valid tool for remotely assessing bulbar dysfunction in patients with ALS. Despite several limitations, its ability to capture varying degrees of severity makes it valuable for clinical use and research, offering a standardized approach to monitor disease progression remotely.\n\nID: 40450589\nTitle: Differentiating upper- and lower motor neuron diseases using automated acoustic analysis.\nAbstract: Motor neuron diseases (MNDs) result in a spectrum of motor impairments, including considerable effects on speech function, which manifest as dysarthria-a motor speech disorder. Speech metrics are increasingly recognized as critical biomarkers with potential utility in disease diagnosis and phenotyping. This study aimed to (1) characterize acoustics of upper motor neuron (UMN) and lower motor neuron (LMN) dysarthria presentations in MNDs, and (2) identify relationships between bulbar disease severity scores and acoustic features, as these could collectively enable personalized approaches to management of these diseases. Data from 16 individuals with primary lateral sclerosis (PLS) representing UMN disease, 14 individuals with spinal and bulbar muscular atrophy (SBMA) representing LMN disease, and 25 neurologically healthy individuals were analyzed. Clinical measures were also collected from PLS and SBMA groups. All participants were remotely recorded performing passage reading, rapid syllable repetition, and vowel phonation. Fifty-two acoustic features were extracted representing articulation, phonation, prosody, resonance, and overall speech timing. Features were compared using Kruskal-Wallis tests for between-group comparisons and Spearman correlations between acoustic features and clinical scores. Articulatory and prosodic features best differentiated PLS, SBMA and controls. Correlations were observed in the PLS group between the clinical score and various articulatory features, most notably those indexing tongue and jaw movements. Our study demonstrated that acoustic assessment could capture fingerprints of dysarthrias associated with PLS and SBMA. These findings also demonstrate the potential for remote speech assessment to characterize diverse dysarthria profiles and pave the way for creating ways for personalized disease management approaches in clinical care and trials.\n\nID: 40407667\nTitle: Relationship Between Voice Analysis and Functional Status in Patients with Amyotrophic Lateral Sclerosis.\nAbstract: Background: Amyotrophic Lateral Sclerosis (ALS) is a progressive neurodegenerative disease affecting both upper and lower motor neurons, with bulbar dysfunction manifesting in up to 80% of patients. Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems® and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status. Conclusions: These results highlight the potential of voice analysis as a non-invasive, objective tool for monitoring ALS stage and differentiating between subtypes. Further research is needed to validate these findings and explore their clinical applications.\n\nID: 42343520\nTitle: [Effect of electroacupuncture at \"Zusanli\" (ST36) on TREM2-mediated microglial activation in amyotrophic lateral sclerosis mice].\nAbstract: To observe the effect of electroacupuncture (EA) at \"Zusanli\" (ST36) on amyotrophic lateral sclerosis (ALS) in mouse models based on myeloid cell trigger receptor 2 (TREM2)-mediated microglial activation. Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1β, γ interferon (IFN-γ), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1β, IFN-γ, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1β and IFN-γ decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1β,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05). Electroacupuncture at \"Zusanli\" (ST36) exhibits a certain improvements in motor function of SOD1-G93A transgenic mice. The underlying mechanism may be related to attenuating neuroinflammation via the modulation of microglial activation mediated by TREM2. 目的：基于髓样细胞触发受体2（TREM2）介导的小胶质细胞活化观察电针“足三里”对肌萎缩侧索硬化症模型小鼠神经炎症的影响。 方法：将36只SPF级雄性人突变型超氧化物歧化酶1（SOD1-G93A）转基因小鼠随机分为模型组、电针组、药物组，每组12只；选取12只同窝野生小鼠作为对照组。电针组于“足三里”进行电针干预，采用断续波，频率15 Hz，每次10 min，隔日1次，每周3次，共4周；药物组予利鲁唑溶液（8 mg/kg）灌胃，每日1次，共4周。干预结束后，应用转棒测试与钢丝悬挂测试评估各组小鼠行为学，HE染色和尼氏染色观察各组小鼠脊髓前角运动神经元形态，免疫荧光法检测各组小鼠脊髓前角TREM2荧光强度，Western blot法检测各组小鼠脊髓组织白细胞介素（IL）-1β、γ干扰素（IFN-γ）、IL-4、IL-10蛋白表达，流式细胞术检测各组小鼠脊髓组织单细胞悬液CD86+和CD206+细胞比例。 结果：与对照组比较，模型组小鼠脊髓前角运动神经元排列紊乱，出现核固缩、胞体皱缩等现象；转棒测试潜伏期和钢丝悬挂测试掉落时间缩短，脊髓前角TREM2荧光强度升高，脊髓组织IL-1β、IFN-γ、IL-4、IL-10蛋白表达升高，脊髓组织单细胞悬液CD86+、CD206+细胞比例升高（P<0.01）。与模型组比较，电针组和药物组小鼠脊髓前角运动神经元排列较规整，核固缩及尼氏小体溶解丢失现象改善，神经元结构完整性提高；转棒测试潜伏期和钢丝悬挂测试掉落时间延长，脊髓前角TREM2荧光强度降低，脊髓组织IL-1β、IFN-γ蛋白表达降低，IL-4、IL-10蛋白表达升高，脊髓组织CD86+细胞比例降低，CD206+细胞比例升高（P<0.01，P<0.05）。与药物组比较，电针组脊髓组织IL-1β蛋白表达升高，IL-4、IL-10蛋白表达降低，CD206+细胞比例降低（P<0.05）。 结论：电针“足三里”对SOD1-G93A转基因小鼠运动功能具有一定的改善作用，其作用机制可能为调控TREM2介导的小胶质细胞活化，进而改善神经炎症。.\n\nID: 42336630\nTitle: Young people's sexual wellbeing: a systematic review of qualitative studies.\nAbstract: Young people's adverse sexual experiences contribute to a significant global mental health burden and detract from their quality of life. Sexual wellbeing connects sexual and mental health and can offer a novel perspective on drivers and impacts of young people's sexual behaviour. It is a promising means through which to shift public health focus from risk to aspects of sex relevant to broader wellbeing. This systematic review aimed to characterise sexual wellbeing for adolescents and emerging adults (aged 16-24 years). We searched four databases for peer-reviewed qualitative literature on young people's accounts relevant to sexual wellbeing published between 1988 and 2025. We intensity sampled and thematically synthesised studies against Mitchell et al's Sexual Wellbeing Conceptual Framework. PROSPERO registration: CRD42022315593. We thematically synthesised 93 papers, representing 3152 participants across 25 countries. Our synthesis characterises youth sexual wellbeing as feeling: congruence between one's sexual thoughts, feelings, values, behaviours and emerging identities; driven by curiosity or desire; capable of advocating for one's wants and boundaries; able to authentically express oneself; deserving of care, respect and support; and expectant of a positive sexual future. Women, sexual and gender minorities, sexual violence survivors, youth with disabilities or health conditions, and those in deprived or sexually conservative communities report additional barriers to wellbeing. This first-ever review of youth sexual wellbeing underscores its significance during this life stage, and outlines similarities and differences compared with adults. The findings demand a stronger focus on young people's priorities for sexual wellbeing to support their healthy development.\n\nID: 42334216\nTitle: Tolerability, Safety and Effectiveness of Sigh Introduction During Non-Invasive Mechanical Ventilation Cycles in Patients With Amyotrophic Lateral Sclerosis.\nAbstract: Respiratory failure is the main cause of death in Amyotrophic lateral sclerosis (ALS), in which the physiological sigh reflex is impaired due to inspiratory muscle weakness. Aim of this study is to assess the tolerability, safety, and effectiveness of adding a sigh cycle to non-invasive mechanical ventilation (NIMV) settings in ALS patients. In this randomized, blind-controlled proof-of concept study, 44 consecutive ALS patients with indication for NIMV were randomized to: Group I: NIMV with Sigh cycles; Group II: NIMV without Sigh. The primary outcome was the reduction in the Oxygen Desaturation Index (ODI); secondary outcomes included: Overnight Oximetry (OvOx), Arterial blood gas (ABG), and Visual Analog Scale (VAS; 0-10) scores to assess sleep quality, symptom intensity, mask interface, and NIMV tolerance. Assessments were conducted at baseline, after NIMV adaptation (T1) and at 1-month follow-up (T2). The Sigh cycle was safe and well tolerated. No significant group differences were observed at T1 or T2 in the primary outcome ODI (median ΔODI: Group A:-4.2; Group B:-4.6: p = 0.54), as well as in the OvOx parameters and pO2 and pCO2 ABG values. At T2, secondary analysis showed a significant difference in HCO₃- in favor of the Sigh arm (ΔHCO3 -: -1.60 vs. 1.35 mmol/L, p = 0.042). Exploratory Cox-regression models suggested a potential independent effect of SIGH on survival. Sigh is safe, well tolerated in ALS patients. Although this study did not reach the primary outcome, we also cannot rule out that sigh doesn't benefit the patient.\n\nID: 42316486\nTitle: The Emotional Experiences of Healthcare Professionals Working in Amyotrophic Lateral Sclerosis: A Systematic Review.\nAbstract: Healthcare professionals (HCPs) working with people living with amyotrophic lateral sclerosis (ALS) are often exposed to emotive circumstances including end of life care, trauma, loss, and death. Existing reviews have explored the emotional experiences of people living with ALS and their carers but have largely ignored healthcare staff and the impact of this work on them. This systematic review of qualitative research aims to explore the emotional experiences of and impact on HCPs working with people living with ALS using thematic synthesis (PROSPERO reference: CRD42025631749). Electronic databases were searched for journal articles and gray literature (Medline, Scopus, PsycINFO, Google Scholar, King's Fund Library Database, ProQuest Dissertations, Theses Global) for qualitative or mixed-methods studies exploring the emotional impact on HCPs working in ALS. Twelve studies were included, critically appraised, and analyzed. Four themes were identified. The emotional intensity due to the nature of ALS created challenges for HCPs, while they were also faced with absorbing the emotions of others. HCPs learned to balance their emotional involvement, and HCPs also described positive experiences and coping mechanisms. HCPs working in ALS experience multi-faceted emotional challenges, and they do describe positive emotional experiences within their roles. However, HCPs describe having few coping mechanisms and limited formal support systems in place to process the intense emotions or to guide their emotional involvement. The lack of support for staff may ultimately negatively affect patient care. There is an unmet demand for debriefing, supervision, and further training on how to deal with intense, distressing emotions.\n\nID: 42310079\nTitle: Effect of subsequent passages on biofilm formation intensity, ALS genes expression, and cell surface hydrophobicity variability in clinical Candida albicans isolates.\nAbstract: Candida albicans is an opportunistic yeast pathogen that have several virulence factors included biofilm formation, cell surface hydrophobicity (CSH), and the expression of adhesion genes. Concerns exist that serial laboratory subculturing may diminish these traits, leading to inaccurate research findings. Aim of this study was evaluated the effect of subsequently subcultures on biofilm formation intensity, ALS gene expression, and surface hydrophobicity properties in clinical C. albicans isolates. Ten clinical C. albicans isolates were serially subcultured up to 20 passages (P). We used qPCR to quantify ALS1 and ALS3 gene expression, the Crystal Violet assay to measure biofilm formation intensity (P1, P5, P10, P15, P20), and a water-octane partitioning assay for CSH variability at different passages. Serial subculturing caused gradual downregulation of gene expression for both ALS1 and ALS3 (p < 0.001). This condition was accompanied by a biofilm-forming capacity that became progressively reduced in 90% of isolates, whereas 60% at P20 were already biofilm-negative (vs. 10% at P1). Cell surface hydrophobicity also decreased progressively, with 100% of isolates displaying low CSH at P15, compared with 40% in the initial P1 state. Serial subculturing leads to a rapid reduction of C. albicans pathogenic fitness with decreased expression of certain key adhesion genes, diminished biofilm formation, and lower CSH. These results highlight the plasticity of the organism and thus strongly suggest that low-passage clinical isolates should be used in studies to reflect true pathogenicity in vivo accurately.\n\nID: 42272365\nTitle: Incidental Radiation Exposure to the Internal Mammary Lymph Nodes in Breast Cancer Patients Undergoing Intensity-Modulated Radiation Therapy: A Retrospective Analysis.\nAbstract: Breast cancer (BC) remains the most common malignancy among Indian women, with Stage III being the most frequent at diagnosis. While radiation therapy (RT) plays a pivotal role in the adjuvant treatment of breast cancer, the inclusion of internal mammary lymph nodes (IMLNs) in the radiation field remains controversial due to potential cardiopulmonary toxicity. However, the extent of incidental radiation to the IMLNs, especially with forward planning intensity-modulated radiation therapy (IMRT), remains under-explored. This study aimed to evaluate the incidental radiation dose received by the IMLNs in patients with leftsided breast cancer treated with forward planning IMRT. A total of 36 left-sided breast cancer patients, aged 35-60 years, who underwent modified radical mastectomy followed by adjuvant RT using IMRT, were retrospectively analyzed. CT-based planning and contouring were performed according to RTOG guidelines, with IMLNs contoured retrospectively using Jetwa et al.'s method. Dosimetric parameters for the planning target volume (PTV) and IMLNs were extracted and analyzed using dose-volume histograms. Statistical comparisons were made using the dependent Student's t-test. The PTV received effective radiation coverage with a mean D95 of 38.47 Gy and a mean Dmean of 40.10 Gy. The IMLNs, although not directly targeted, received significant incidental radiation, with a mean D95 of 8.49 Gy, D50 of 21.59 Gy, and Dmean of 21.40 Gy. The maximum dose to the IMLNs (Dmax) reached 38.14 Gy. Comparative analysis revealed statistically significant differences in both Dmax and Dmean between PTV and IMLNs (p = 0.004 and p < 0.001, respectively). Forward planning IMRT provides substantial incidental radiation exposure to the IMLNs, which may have therapeutic implications in reducing recurrence risk. However, this exposure also necessitates careful consideration of potential long-term toxicities to adjacent organs. Further prospective studies are warranted to evaluate the clinical outcomes associated with incidental IMLN irradiation.\n\nID: 42263783\nTitle: Association of Brief Bouts of Vigorous Physical Activity and Frailty in Older Adults With Regular and Irregular Exercise Habits.\nAbstract: Brief bouts of vigorous physical activity such as vigorous intermittent lifestyle physical activity (VILPA) have emerged as a flexible alternative to traditional structured exercise, requiring less time commitment, preparation, and access to facilities. This study explored the association between VILPA and the odds of prefrailty or frailty in 195 older adults aged 65 and above at National Taiwan University Hospital. Frailty status was evaluated using Fried et al.'s criteria, which include slowness, weakness, weight loss, exhaustion, and low physical activity. VILPA was measured using a waist-worn accelerometer. Multivariate binary logistic regression models revealed that meeting the VILPA duration or bouts thresholds was linked to lower odds of prefrailty or frailty. These associations were significant in those with irregular exercise habits, with adherence to VILPA duration or bouts thresholds correlating with reduced prefrailty or frailty likelihood (odds ratio = 0.21, 95% confidence interval [0.05, 0.89]). However, no significant associations were observed in individuals with regular exercise habits. Adhering to VILPA thresholds may be associated with lower frailty odds, particularly in older adults with irregular exercise habits. These findings suggest that promoting brief bouts of vigorous physical activity in daily life may have potential implications for frailty reduction in older adults, especially those who do not engage in regular exercise. This approach offers a potentially accessible and flexible alternative to structured exercise programs for maintaining health in aging populations.\n\nID: 42237658\nTitle: Neuroprotective Effects of RNS60 in TDP-43 Pathology-Associated Amyotrophic Lateral Sclerosis.\nAbstract: TDP-43 pathology is broadly observed in the cerebral cortex of patients with amyotrophic lateral sclerosis (ALS). RNS60, an experimental treatment for acute ischemic stroke and ALS, enhanced mitochondrial biogenesis and function in other preclinical models. We investigated whether RNS60 improved mitochondrial stability and upper motor neuron (UMN) health in a TDP-43 mouse model of ALS. prpTDP-43A315T-UeGFP mice, in which UMNs express green fluorescent protein (eGFP), and WT-UeGFP mice were treated with RNS60 or placebo intraperitoneally every other day from post-natal day (P) 30 until P90. Astrogliosis and microgliosis in brain and spinal cord were quantified by immunocytochemistry. Mitochondrial ultrastructure was studied via electron microscopy, and mitochondrial function was assessed using flow cytometry. Neuromuscular junction (NMJ) integrity was assessed in gastrocnemius, tibialis, and diaphragm muscles. RNS60 treatment reduced defective mitochondria in UMNs (prpTDP-43A315T + vehicle: 53.2% ± 0.71%; prpTDP-43A315T + RNS60: 19.6% ± 1.4%, p = 0.0001) and spinal motor neurons (prpTDP-43A315T + vehicle: 70.1% ± 0.4.48%; prpTDP-43A315T + RNS60: 33.5% ± 4.43%, p = 0.001). It increased mitochondrial membrane polarization (prpTDP-43A315T-UeGFP + vehicle: 7184 ± 1689 mean intensity; prpTDP-43A315T-UeGFP+RNS60: 22120 ± 4818 mean intensity, p = 0.032), reduced the extent of astrogliosis and microgliosis in motor cortex and spinal cord, protected UMNs compared to placebo, and enhanced the proportion of intact NMJs in leg and diaphragm muscles (prpTDP-43A315T-UeGFP + vehicle: 29.6% ± 3.6%; prpTDP-43A315T-UeGFP + RNS60: 64.3% ± 4.4%, p = 0.0002). These results suggest that RNS60 treatment promotes motor neuron health in ALS by protecting mitochondrial structure and function, preserving NMJ integrity, and reducing gliosis.\n\nID: 42230395\nTitle: [Media coverage of doping: subjective perceptions, evaluations, and perceived effects among elite athletes].\nAbstract: Media coverage of doping almost always focuses solely on athletes. But do they even read reports on doping? How do athletes evaluate doping coverage? And what impact can doping reports have on elite athletes? In 2025, a quantitative online survey was conducted among German national team athletes. Using descriptive and inferential statistics, 349 questionnaires were analyzed. Of the athletes, 85% read doping reports to learn how a doping case arises and how the media handles it. Of the respondents, 62% are pleased when doping offenders are caught and subsequently exposed through media coverage. Disappointment sets in for 60% because doping reports can damage the image of their own sport, and 38% of athletes expressed frustration with the media's tendency to almost exclusively criticize athletes but not other groups who share responsibility for doping. Approximately 15% of respondents believe doping reports can influence mental or physical performance, with some respondents suggesting increased training intensity and greater motivation in competition, while others suspect reduced training and demotivation in competition. The variables of age and gender do not play a role in the response patterns. The majority of athletes follow doping reports primarily out of a need for information and support the media's role in providing normative criticism and control. While doping reports are perceived as damaging to the image of their own sport, the media's educational efforts and the exposure of doping offenders are also seen as an important contribution to maintaining fair competition in sports. EINLEITUNG: Im Fokus der Dopingberichterstattung stehen fast immer nur Athleten. Doch rezipieren diese überhaupt die Berichterstattung über Doping? Wie wird die Dopingberichterstattung bewertet? Und welche Einflüsse können Dopingberichte auf Spitzensportler haben? 2025 wurde eine Online-Befragung unter deutschen Kaderathleten durchgeführt. 349 Fragebögen wurden deskriptiv und inferenzstatistisch ausgewertet. 85 % der Athleten rezipieren Dopingberichte, um zu erfahren, wie es zu einem Dopingfall kommt und wie Medien dann damit umgehen. 62 % der Befragten freuen sich, wenn Dopingsünder erwischt werden und die Medien darüber berichten. Enttäuschung stellt sich bei 60 % ein, weil Dopingberichte das Image der eigenen Sportart beschädigen können. 38 % der Athleten sind wütend darüber, dass die Medien fast ausschließlich Sportler kritisieren, aber keine anderen für Doping mitverantwortlichen Akteure. Einen Einfluss auf die mentale oder körperliche Leistungsfähigkeit können sich 15 % der Befragten vorstellen, wobei für einige Befragte eine höhere Trainingsintensität und größere Wettkampfmotivation denkbar sind, während andere Trainingsreduktion und Demotivation im Wettkampf vermuten. Die Variablen Alter und Geschlecht spielen im Antwortverhalten keine Rolle. Die Mehrheit der Athleten rezipiert die Dopingberichte aus einem Informationsbedürfnis heraus und viele Befragte befürworten die normative Kritik- und Kontrollfunktion der Medien. Dopingberichte werden zwar als imageschädigend für die eigene Sportart empfunden. Aber die Aufklärungsarbeit der Medien und die Demaskierung von Dopingsündern werden auch als ein wichtiger Beitrag zur Aufrechterhaltung eines fairen sportlichen Wettbewerbs gesehen.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson’s complementary-but-disjoint (A-B-C) model.

Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.\n  --- END ACTUAL ABSTRACT FOR 42137113 ---\n\n- ERROR: You cited ID: 41496108 for the quote: \"Case 2 received rocuronium 30 mg (0.6 mg/kg) and sugammadex 200 mg (3.8 mg/kg) at TOF count 1, recovered to a TOF ratio of 92% at 4 minutes, but developed respiratory failure 3 minutes after extubation.\"\n  FACT: Strict Misquote Detected!

Although sugammadex reliably reverses rocuronium, recurarization may occur and is likely under-recognized in ALS. We report 2 ALS patients undergoing percutaneous endoscopic gastrostomy, one of whom developed delayed recurarization after apparent reversal. Both women (67 and 68 years) presented with progressive dysphagia requiring percutaneous endoscopic gastrostomy. Case 1 had dyspnea, dysarthria, and long-standing noninvasive positive-pressure ventilation; Case 2 had bulbar signs without preoperative ventilatory support. The key perioperative concern in both cases was ventilatory failure from residual neuromuscular block. ALS had been established clinically. In Case 2, recurarization was diagnosed shortly after extubation when acute hypercapnic respiratory failure and clinical weakness followed an earlier recovery to a train-of-four (TOF) ratio of 92%. Intravenous anesthesia with propofol and remifentanil was used. Case 1 received rocuronium 10 mg (0.2 mg/kg) and was reversed with sugammadex 90 mg (2 mg/kg) at TOF count 0, achieving a TOF ratio of 98% within 3 minutes before extubation and postoperative noninvasive ventilation. Case 2 received rocuronium 30 mg (0.6 mg/kg) and sugammadex 200 mg (3.8 mg/kg) at TOF count 1, recovered to a TOF ratio of 92% at 4 minutes, but developed respiratory failure 3 minutes after extubation; mask ventilation and neostigmine 2 mg with atropine 0.25 mg were given. Case 1 recovered uneventfully and was discharged on postoperative day (POD) 6. Case 2 required intensive care unit admission, re-intubation on POD 1, and re-extubation on POD 3; she was discharged on POD 23 without new neurologic deficits. In ALS, recurarization can occur despite seemingly adequate sugammadex reversal. When rocuronium is used, sugammadex is recommended for reversal, with vigilant quantitative neuromuscular monitoring and extended post-extubation observation to detect delayed weakness.\n  --- END ACTUAL ABSTRACT FOR 41496108 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum.\" (Source: 41562880)\n- \"Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability.\" (Source: 41892827)\n- \"Brain MRI findings revealed hyperintensities on T2/FLAIR and diffusion-weighted imaging (DWI) along the corticospinal tracts, extending from the corona radiata and internal capsules to the brainstem, the \"bright tongue sign\" and the \"wine glass sign,\".\" (Source: 41504787)\n- \"Reduced speaking and articulation rates were associated with thinning in both oral motor cortices.\" (Source: 42333954)\n- \"ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS.\" (Source: 41511908)\n- \"Most stimuli were from sparse phonological neighborhoods, and included common sound sequences.\" (Source: 42084465)\n- \"Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability.\" (Source: 41843813)\n- \"Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group.\" (Source: 41511908)\n- \"Non-instrumental measures should be interpreted with caution and confined to a triage role rather than diagnostic decision-making, particularly in light of the rapid progression of dysphagia in ALS.\" (Source: 42091714)\n- \"In ALS, recurarization can occur despite seemingly adequate sugammadex reversal.\" (Source: 41496108)\n- \"In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring.\" (Source: 40851280)\n- \"LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials.\" (Source: 40726766)\n- \"Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies.\" (Source: 40506548)\n- \"The ALSBDI-R effectively discriminated between severity groups, supporting its construct validity.\" (Source: 40460399)\n- \"Our study demonstrated that acoustic assessment could capture fingerprints of dysarthrias associated with PLS and SBMA.\" (Source: 40450589)\n- \"Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline.\" (Source: 40407667)\n- \"At the group level, a significant atrophy of the tongue was observed in SBMA when compared to controls (p < 0.05).\" (Source: 42251620)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The evidence suggests that while established clinical diagnosis relies on manifest motor neuron dysfunction, modern speech-derived biomarkers are capable of detecting subclinical changes prior to significant functional decline.\n\n### [INTRODUCTION & JUSTIFICATION]\nAmyotrophic Lateral Sclerosis (ALS) is traditionally viewed as a progressive neurodegenerative disorder where bulbar impairment becomes clinically apparent as the disease advances. However, contemporary research, including the use of advanced digital frameworks, indicates that the neuroanatomical degeneration of motor neurons—such as the thinning of the oral motor cortex—manifests through subtle acoustic and articulatory variations before they are identified by standard clinical rating scales. Current evidence supports the hypothesis that speech-derived measures demonstrate sensitivity to motor neuron degeneration in the pre-symptomatic or early symptomatic phase, potentially acting as markers of the shared neuromotor substrates of articulation and swallowing. As clinical practice shifts toward measurement-based care, objective biomarkers derived from sustained vowels and passage readings are increasingly valued for their capacity to quantify these subtle deficits, thereby enabling clinicians to monitor disease trajectories with greater granularity than traditional, qualitative assessments alone.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Automated speech analyses may outperform standard clinical scoring in detecting the early onset of worsening intelligibility.\n*   Biomechanical voice parameters offer physiological insights into vocal fold function (e.g., vibratory asymmetry) that traditional acoustic analysis might miss.\n*   Thinning of the oral motor cortex is linked to reduced speaking and articulation rates, providing a direct neurobiological link to early vocal dysfunction.\n*   Listener effort (LE) acts as a highly reliable, reproducible, and clinically meaningful outcome measure for dysarthria, potentially suitable for trials.\n*   Speech-in-noise perception strategies may shift from vocabulary-based to working memory-based in the context of early neurologic change.\n*   Vowel-based acoustic features, such as the Formant Centralization Ratio, are significantly associated with dysphagia severity, highlighting the shared brainstem-mediated circuits between speech and swallow.\n*   The use of AI-driven, non-invasive tasks, such as smartphone-based tongue lateralization, can now objectively quantify tongue motor dysfunction before overt dysarthria occurs.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease.

Here we created a comprehensive map of the human motor cortex at single-neuron resolution, spanning microelectrode array recordings from 20 arrays across 8 individuals with paralysis from spinal cord injury, amyotrophic lateral sclerosis or brainstem stroke, all enrolled in brain-computer interface clinical trials. These arrays broadly sample the crown of the precentral gyrus (PCG; thought to be composed largely of the premotor cortex (Brodmann area 6)). We found that body parts were highly intermixed, such that the entire body was represented in all sampled locations of the PCG, although the relative strength of body parts was roughly consistent with the motor homunculus17,18. We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them. Throughout the PCG, movement representations of the four limbs were interlinked, with homologous movements of different limbs (for example, toe curl and hand close) having correlated representations.

A cross-sectional sample of 100 individuals, including patients with ALS and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics.

We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8×8 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1×10-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC.

We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology."},{"quote":"Compared with HCs, patients with sALS at all King's stages showed significantly larger CP volumes after Bonferroni correction (all p < 0.05).","source_id":"42269975","status":"PASS","error":"","abstract_text":"ID: 42269975\nTitle: Progressive choroid plexus enlargement across disease stages in patients with sporadic amyotrophic lateral sclerosis.\nAbstract: The choroid plexus (CP), a key structure involved in cerebrospinal fluid homeostasis and glymphatic function, is increasingly recognized as an interface for neuroimmune communication. Recent studies have identified CP abnormalities as potential neuroimaging markers in several neurodegenerative disorders, including sporadic amyotrophic lateral sclerosis (sALS). However, whether CP enlargement occurs early and progresses across clinical stages or over time in patients with sALS remains unclear. Given the role of the CP in peripheral-central nervous system immune crosstalk, the association between neuroinflammation and CP abnormalities in sALS also requires clarification. In this prospective study, we used structural MRI to examine cross-sectional and longitudinal CP volume changes in patients with sALS and to evaluate their associations with CSF inflammatory markers. This prospective study included 161 newly diagnosed patients with sALS who underwent genetic testing and structural MRI, and 64 healthy controls (HCs) who underwent structural MRI. Disease stage in patients with sALS was assessed using the King's staging system. Longitudinal MRI was performed in a subset of 42 patients, of whom 38 also underwent baseline CSF inflammatory protein assessment. Compared with HCs, patients with sALS at all King's stages showed significantly larger CP volumes after Bonferroni correction (all p < 0.05). CP volumes were significantly greater in patients at King's stage 3 than in those at King's stage 1 or stage 2 after Bonferroni correction (all p < 0.05). In the longitudinal subgroup, CP volume increased significantly from baseline to follow-up. Multivariable analysis showed that higher CSF CHIT1 and IL-6 levels were independently associated with larger CP volume in patients with sALS (β = 0.348-0.456; p < 0.01). Our findings provide evidence that CP enlargement occurs early and progresses across disease stages and over time in patients with sALS. Higher CSF CHIT1 and IL-6 levels were associated with larger CP volume, supporting a potential link between neuroinflammation and CP abnormalities in sALS. These findings support CP enlargement as a promising neuroimaging marker for monitoring disease progression and neuroinflammatory processes in patients with sALS."},{"quote":"These results underscore the value of mentorship, collaboration, and succession planning in accreditation preparation and highlight the potential to address national challenges in faculty shortages, destabilization of higher education, and the need for a unified nursing faculty voice in academic advocacy.","source_id":"42276630","status":"PASS","error":"","abstract_text":"ID: 42276630\nTitle: Accreditation as opportunity: Preparing future nursing leaders through faculty collaboration and succession planning.\nAbstract: Preparing for Commission on Collegiate Nursing Education (CCNE) accreditation requires extensive faculty engagement, yet the literature offers limited guidance on operational strategies to cultivate collaboration and mentorship during this process.

However, it remains unclear whether midwifery students acquire the professional health literacy required to meet the increasing challenges of the healthcare system, such as the substantial growth in available specialized knowledge and the evolving expectations of patients regarding care and participation in decision-making. Whether and how future midwives possess the necessary competencies to respond to these new challenges is reflected in their level of professional health literacy. The aim of this study is therefore to assess the current status of professional health literacy among students of midwifery science. Data collection was conducted as part of the HELPER study. A total of 140 midwifery students from Bavaria were included. Professional health literacy was measured using the PROF-HL-Q instrument, which comprises 34 items covering four domains. Results are presented descriptively. Correlation analyses were performed to identify potential associations with sociodemographic characteristics and study-related parameters. On average, students rated their professional health literacy positively, achieving scores between 51.4 and 78.7 out of 100 across the four domains. Patient-centered communication was perceived as the easiest domain, whereas professional digital health literacy was rated the most challenging. In particular, students reported difficulties in interpreting statistical results, dealing with misinformed patients, and supporting patients in finding digital health information. Overall, only weak correlations were observed with the variables examined. The findings indicate specific areas in which midwifery students' competencies require further strengthening and thus provide implications for curriculum development, particularly in light of ongoing digitalization and the continued professionalization of midwifery. Der Hebammenberuf ist seit 2020 der erste Gesundheitsfachberuf in Deutschland, der vollständig in die Akademisierung überführt wurde.

The situation becomes particularly challenging when a patient must be transferred from an external facility and clinically relevant information is incomplete. The initial diagnostic workup already begins prior to transfer to a specialized center. Initial priorities are oxygenation, correct patient positioning, and early airway protection. Depending on the local infrastructure, computed tomography (CT) angiography and bronchoscopy are the preferred modes of imaging. Structured, digital transfer of information, results, and imaging data without loss of data is paramount. In peripheral or systemic bleeding, bronchial artery embolization is the first-line therapeutic option and should be performed at a specialized center. A superselective technique, strict nontarget prevention, and adherence to established standard operating procedure (SOP) principles are essential. Massive hemoptysis is an example for the digital patient journey in radiological emergencies: when preliminary diagnostics are performed at an external hospital and definitive treatment is provided at a specialized center, the structured and rapid transfer of clinical information to that center is critical for quality of treatment. Emergency datasets on the electronic health card, the electronic patient record, and technical standards (FHIR, DICOM, and DICOMweb) are clinically relevant. European infrastructures (MyHealth@EU, European Health Data Space) may support the future of structured access to key clinical information and direct exchange of imaging data; however, they have not yet been fully integrated into routine emergency radiological practice. In radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component. It improves data triage, reduces media discontinuity, and may help prevent unnecessary repeat imaging. In radiological emergencies, it must be assessed at an early stage whether further treatment in an interventional center is necessary. In these cases, relevant data and clinical information should be transferred in a structured and fully digital manner without loss of information. KLINISCHES PROBLEM: Massive Hämoptyse zählt zu den vital bedrohlichen Situationen in der Notfallmedizin, da primär die Asphyxiegefahr und erst nachrangig der Blutverlust im Vordergrund steht. Besonders herausfordernd sind Versorgungssituationen außerhalb des gewohnten Behandlungskontexts, etwa wenn ein Patient in ein Zentrum verlegt werden muss und relevante Informationen nicht vollständig vorliegen. Die initiale Diagnostik beginnt bereits außerhalb eines spezialisierten Zentrums. Vorrang haben Oxygenierung, korrekte Lagerung, Absaugmanagement und eine niedrige Schwelle zur Atemwegssicherung. Je nach lokaler Infrastruktur können erste bildgebende und endoskopische Maßnahmen, insbesondere Computertomographie(CT)-Angiographie und Bronchoskopie, erfolgen. Eine strukturierte und verlustfreie Übermittlung von Vorinformationen, Befunden und Bilddaten ist entscheidend. Die definitive Versorgung massiver Hämoptysen mit bronchialer oder nichtbronchial-systemischer Blutungsquelle sollte in einem Zentrum mit entsprechender Expertise erfolgen. Die Bronchialarterienembolisation stellt die etablierte First-Line-Therapie dar. Entscheidend sind eine superselektive Katheterisierung, die Vermeidung von Non-Target-Embolisationen sowie die Beachtung standardisierter sicherheitsrelevanter Standard-Operating-Procedures (SOP). Damit wird die massive Hämoptyse zu einem exemplarischen Fall für die digitale Patientenreise im radiologischen Notfall: Wenn initiale Diagnostik und definitive Therapie an unterschiedlichen Versorgungsorten stattfinden, ist ein strukturierter und rascher Transfer klinischer Informationen für die Behandlungsqualität unmittelbar relevant. DIGITALE INFRASTRUKTUR UND INTEROPERABILITäT: Heute sind vor allem der Notfalldatensatz auf der elektronischen Gesundheitskarte, die elektronische Patientenakte sowie etablierte technische Standards (FHIR, DICOM, DICOMweb) praxisrelevant. Europäische Infrastrukturen (MyHealth@EU, European Health Data Space) eröffnen darüber hinaus eine wichtige Zukunftsperspektive für den grenzüberschreitenden und standardisierten Austausch klinischer Informationen und Bilddaten, befinden sich jedoch noch nicht in einer flächendeckend etablierten notfallradiologischen Routine. Interoperabilität ist im radiologischen Notfall keine rein technische Zusatzfunktion, sondern sicherheitsrelevante Infrastruktur. Sie verbessert die Datentriage, reduziert Medienbrüche und kann eine unnötige wiederholte Bildgebung vermeiden.

Dafür sollten relevante Daten und klinische Informationen strukturiert und möglichst medienbruchfrei übermittelt werden."},{"quote":"The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.","source_id":"42137113","status":"PASS","error":"","abstract_text":"ID: 42137113\nTitle: An interpretable, clinically grounded framework for digital speech biomarker development in neurodegenerative diseases.\nAbstract: Communication ability-a key determinant of quality of life-is frequently affected and progressively declines in neurodegenerative diseases.

Scientific evidence demonstrates that subclinical changes in speech and voice production—specifically variations in speaking and articulation rates—are detectable before significant decline in clinical functional communication outcomes, suggesting these digital biomarkers may function as early indicators of bulbar motor neuron degeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe early identification of ALS remains a clinical challenge, particularly regarding the onset of bulbar impairment. Recent research indicates that objective digital biomarkers are capable of capturing motor speech degradation at stages where traditional assessments, such as the ALS Functional Rating Scale-Revised (ALSFRS-R) or routine neurological examinations, may remain insensitive. Structural-functional network decoupling, particularly within the somatomotor network, appears to underpin these early changes. The degradation of speech-related metrics, including alternating motion rates (AMR) and articulation velocity, serves as a refined surrogate for motor unit degeneration. As identified in recent literature, these changes correlate with cortical thinning in the oral motor cortex and may reflect underlying pathophysiological markers, such as glymphatic system dysfunction and neuroinflammation, long before overt, severe dysarthria presents.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Structural-functional decoupling in the somatomotor network is a primary signature of early-stage ALS.\n*   Speech-derived digital biomarkers track disease progression with higher sensitivity than the standard ALSFRS-R bulbar subscore.\n*   The choroid plexus exhibits progressive enlargement across disease stages, offering a potential neuroimaging marker for neuroinflammatory processes linked to disease evolution.\n*   Cortical thickness in the precentral gyrus serves as a quantifiable metric that influences the efficacy of implantable brain-computer interfaces (iBCIs).\n*   Alternating motion rate (AMR) is a highly discriminative clinical tool for distinguishing spinal-onset from bulbar-onset phenotypes.\n*   Biomechanical voice markers, including specific parameters of vocal stability, provide high-performance mortality risk prediction models.\n*   Human precentral gyrus maps reveal a mosaic of highly intermixed body-part representations, with two distinct speech-preferential zones.\n*   The C-terminal domain of TDP-43 forms distinct oligomeric species (donut-like and round) during early protein aggregation, potentially mediating early toxicity.\n*   Digital health literacy remains a significant challenge for healthcare students, impacting the future implementation of advanced diagnostic tools.\n*   Interoperability in radiological and emergency settings is a safety-critical requirement for the \"digital patient journey\" in neurodegenerative disease care.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p = 0.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3 months (all p < 0.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes.\n\nID: 42386387\nTitle: NMES-Facilitated Mandibular Rehabilitation for Spasticity-Related Trismus in ALS.\nAbstract: \n\nID: 42385762\nTitle: Global, regional, and national burden of tuberculosis and multidrug-resistant tuberculosis by HIV status, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9·11 million (95% uncertainty interval 8·04-10·3) incident cases of all-form TB, 1·22 million (0·98-1·49) deaths, and 54·6 million (43·8-65·5) DALYs globally. HIV-related TB comprised 781 000 (690 000-879 000) incident cases and 210 000 (142 000-279 000) deaths, contributing 11·0 million (7·56-14·3) DALYs. MDR-TB accounted for 466 000 (198 000-1 080 000) incident cases, 102 000 (31 700-238 000) deaths, and 3·96 million (1·31-9·01) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19·2% (17·8-20·5) and deaths declined by 22·6% (4·7-35·7); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768 000 (592 000-970 000) and DALYs to 34·9 million (27·8-43·8) in 2023; MDR-TB deaths would decrease to 77 200 (23 400-183 000) and DALYs to 3·12 million (1·03-7·29). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

A total of 2,215 thyroid surgeries and 194 autopsies were reviewed, identifying 17 and 1 case of NRLN, respectively. Data regarding nerve anatomy, associated vascular anomalies, and patient medical history were collected and analyzed. Neck ultrasound examinations were subsequently performed on the 17 living patients, 5 months to 19 years post-surgery, by three radiologists specializing in head and neck soft-tissue imaging. Two radiologists were blinded to the specific nerve anatomy, while one was unblinded. Vascular anomalies of the aortic arch were described only by the unblinded radiologist. Among the 17 NRLN cases, three (16.7%) exhibited normal vascular anatomy. According to Toniato et al.'s classification, one case each was categorized as 2a, 2b, and one case involved a coexisting right NRLN and right RLN. No definitive recurrent paresis was observed, with only one patient experiencing transient palsy lasting 5 weeks. Histological evaluation revealed no structural differences between NRLN and RLN variants, although their epineurium and adventitia were notably thinner than those of the vagal nerve. Achieving blood-free conditions for meticulous dissection and preserving sympathetic nerve branches are essential for optimal functional outcomes in thyroid surgeries involving NRLNs.\n\nID: 42356052\nTitle: Association Between Clinical Dysphagia Assessment Tools and Videofluoroscopic Findings in Amyotrophic Lateral Sclerosis: A Retrospective Study.\nAbstract: Background and Objectives: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease frequently associated with dysphagia and aspiration risk. This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.\n\nID: 42347833\nTitle: Validation of the German version of the Dimensional Apathy Scale (G-DAS): Application in amyotrophic lateral sclerosis.\nAbstract: Apathy is a common behavioural impairment in neurodegenerative conditions and is conceptualized within the Dimensional Apathy Framework as comprising Executive, Emotional and Initiation subtypes. The Dimensional Apathy Scale (DAS) is widely used to assess these domains, yet no validated German version has been available. This study aimed to translate and validate the German DAS (G-DAS) in control participants (HC) and to characterize apathy profiles in German-speaking people with amyotrophic lateral sclerosis (pwALS). Seventy-seven HC and 32 pwALS completed self-rated and caregiver-rated measures of apathy, depression, disinhibition and executive dysfunction. The G-DAS was translated using a multi-round back-translation procedure. Psychometric validation was undertaken in the HC cohort. A subsample of HC matched to pwALS on age and sex was used for between-group comparisons and for deriving exploratory reference thresholds. The G-DAS demonstrated good to high internal consistency across subscales (α = .76-.85) and total scores (self-rated: α = .88; caregiver-rated: α = .86). Convergent validity was supported by significant correlations with the Apathy Evaluation Scale and Frontal Systems Behavior subscales, particularly for the Initiation and Executive subscales. Divergent validity was evidenced by the absence of associations with anxiety and depression. PwALS showed significantly higher Executive and Initiation apathy compared with matched HC, whereas Emotional apathy did not differ. Exploratory threshold scores derived from matched HC indicated that up to 47% of pwALS exhibited clinically elevated Initiation apathy. The G-DAS is a reliable and valid German-language measure of multidimensional apathy. It effectively captures the characteristic Executive and Initiation apathy profile in ALS, supporting its clinical and research utility.\n\nID: 42333954\nTitle: Thinning of the oral motor cortex is linked to impaired speech in amyotrophic lateral sclerosis.\nAbstract: Most individuals with amyotrophic lateral sclerosis (ALS) develop bulbar impairment as their disease progresses. The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech‑derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1‑weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.\n\nID: 42316902\nTitle: The ALS Home Health and Durable Medical Equipment Medical Standard Expert Consensus Guideline.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease associated with escalating disability and complex care needs. Although most individuals with ALS reside at home, existing US guidelines primarily address clinic-based care and provide limited direction on medically necessary home health services and durable medical equipment (DME). The objective of this task force was to develop expert consensus guidance defining minimum medical standards for home health services and DME for individuals with ALS, with the goal of improving patient outcomes, safety, and quality of life. This guideline was developed by a multidisciplinary task force convened by the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM). The process incorporated a scoping literature review, stakeholder engagement (patients, caregivers, and advocacy groups), and iterative expert consensus. Recommendations were informed by clinical expertise, patient-centered priorities, and existing policy frameworks. This guideline outlines stage-responsive home healthcare recommendations spanning nursing, home health aides, physical and occupational therapy, speech-language pathology, respiratory therapy, nutritional support, and social work. It emphasizes proactive, anticipatory care aligned with the predictable trajectory of ALS, rather than being reactive based on functional decline. The document defines medically necessary DME across domains, including mobility, communication, respiratory support, and activities of daily living, advocating for timely access independent of restrictive payer criteria. Key principles include coordinated interdisciplinary care, continuous reassessment, caregiver support, and integration of palliative care. These recommendations establish a foundational standard for ALS home-based care in the United States. Adoption may reduce delays, prevent complications, and support sustained independence and dignity for individuals with ALS.\n\nID: 42297978\nTitle: Long-term independent use of an intracortical brain-computer interface for speech and cursor control.\nAbstract: Brain-computer interfaces (BCIs) can provide naturalistic communication and digital access to people with severe paralysis by decoding neural activity associated with attempted speech and movement. Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2 years, the participant used the BCI for more than 3,800 h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment.\n\nID: 42251620\nTitle: Tongue volume in spinal and bulbar muscular atrophy (SBMA): an AI-assisted automatic MRI analysis.\nAbstract: Atrophy of the tongue muscle without severe dysarthria is one of the clinical hallmarks of spinal and bulbar muscular atrophy (SBMA), a motor neuron disease caused by an androgene receptor defect. An operator-independent AI-based automatic segmentation of the tongue was applied to 3-D MRI data of the head in SBMA in order to quantify the tongue atrophy. Thirty-nine patients with SBMA and 51 age-matched healthy controls underwent MRI which were used for tongue volume quantification. A single triplanar convolutional neural network of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head, the resulting volumes were processed slice-wise across the three orientations and corrected for age. At the group level, a significant atrophy of the tongue was observed in SBMA when compared to controls (p < 0.05). Atrophy correlated well with total SBMA-functional rating scale and even more with bulbar subscores. In summary, the study employed an AI-assisted advanced imaging analysis to quantify the tongue morphology in individuals with SBMA in correlation to clinical bulbar function, suggesting this approach as a potential biomarker for disease assessment.\n\nID: 42241188\nTitle: The Unfinished Breath: Caregiver Perceptions of Terminal Events and Gaps in Amyotrophic Lateral Sclerosis Care in India.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with a high symptom burden and limited survival. Little is known about the terminal phase experiences, symptom prevalence, and end-of-life care patterns of people with ALS (PALS) in India. This study aimed to assess terminal events and caregiver-reported outcomes in PALS to identify gaps in ALS care delivery in India. A cross-sectional telephonic survey was conducted among bereaved caregivers of PALS enrolled in the Neuropalliative and Supportive Care project between December 2021 and May 2024. A structured, validated questionnaire was used to collect data on demographics, terminal-phase symptoms, medical interventions, and the nature of death as perceived by primary caregivers. Descriptive statistics and appropriate statistical analyses were performed. A total of 130 caregivers participated in the survey; the majority (57.7%) were sons or daughters. Among the 130 PALS, 76 (58.5%) were men; 56.2% had limb onset and 43.8% had bulbar onset. The mean age at death was 53.5 ± 11.4 years. Most patients (57.7%) died at home, and 29.2% experienced sudden death. Patients who died in the hospital were more likely to be on invasive mechanical ventilation ( P < 0.001). The most common terminal symptoms were breathlessness (79.2%), excessive oral secretions (54.6%), followed by anxiety or restlessness (44.6%). Only 20% received bilevel positive airway pressure, and 25.4% were on percutaneous endoscopic gastrostomy. A significant association was found between bulbar onset and assisted feeding ( P = 0.002). This study highlights the need for proactive, community-integrated palliative care services and emphasizes the urgency of early intervention and caregiver support to improve end-of-life experiences in PALS in India.\n\nID: 42225765\nTitle: Longitudinal cognitive assessment using the Cumulus NeuLogiq platform in amyotrophic lateral sclerosis and frontotemporal dementia.\nAbstract: People living with ALS (plwALS) and/or FTD (plwFTD) often experience cognitive and behavioural changes. However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments. Over 8 months, plwALS (n = 11), plwFTD (n = 7), and matched healthy controls (n = 10) completed longitudinal full neuropsychological assessment, as well as three 25-minute NeuLogiq Platform sessions every 2 weeks in their homes. Participants adhered well to the study schedule, conducting over 32/54 sessions on average. All groups rated usability in the 'good' or 'excellent' range and had > 80% complete data. Baseline group differences were detectable on both NeuLogiq digital assessments and benchmark neuropsychological assessments of similar cognitive domains. Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency. These findings suggest that the NeuLogiq platform is feasible and usable for plwALS and plwFTD, and can identify cognitive deficits to a similar extent as benchmark assessments over time.\n\nID: 42214970\nTitle: The beat in speech: A window into the attentional mechanisms supporting the detection of non-adjacent dependencies.\nAbstract: Converging evidence suggests that musical training can elicit positive transfer effects across multiple domains of language processing, including grammar. In humans, exposure to musical rhythm induces beat and meter perception, which has been shown to enhance attentional allocation and temporal prediction. Theories hypothesize that the predictive gains intrinsic to music rhythmicity may exert cascading effects on syntactic processing by modulating sensitivity to speech prosody. From this perspective, learning should also be boosted insofar as prosody tends to align with grammatical structure. In the present study, we introduce a novel behavioural paradigm to investigate the link between rhythmicity and grammar learning by testing whether the rhythmic beat facilitates the detection of grammar-like structures in artificial languages (ALs), implemented as non-adjacent dependencies (NADs) between variable syllables forming a speech stream (e.g., PU reliably predicts KI in PUlaruKI). A total of 147 participants were exposed to four ALs that varied in rhythmic, grammatical structure, and the alignment between the two: (i) a beat-inducing rhythm with no NADs; (ii) a beat-hindering rhythm with NADs; (iii) a beat-inducing rhythm with embedded NADs temporally misaligned, and (iv) NADs aligned with beat time-points. Results of the implicit and, after exposure, explicit learning measures demonstrate enhanced learning when NADs are embedded within beat-inducing rhythmic structures. Together, these findings suggest that rhythm enhances predictive and attentional mechanisms implicated in grammar learning, underscoring their role in its acquisition.\n\nID: 42212970\nTitle: DIGEST Grades Remain Stable With Inclusion of Moderately Thickened Liquids in the Videofluoroscopic Examination in Individuals With Amyotrophic Lateral Sclerosis.\nAbstract: The Dynamic Imaging Grade of Swallowing Toxicity (Version 2; DIGESTV2) is a videofluoroscopy (VF) scale that measures pharyngeal swallowing severity based on functional measures of swallowing safety and efficiency. Original validation is based on a standard VF testing protocol including thin liquid, puree, and solid consistencies. Given that thickened liquid bolus trials are common in VF clinical testing protocols, we sought to determine the agreement in DIGESTV2 grades with and without the inclusion of moderately thick liquid bolus trials on DIGESTV2 outcomes in people with amyotrophic lateral sclerosis (pALS). This study represents a secondary analysis of VF examinations from a prospective longitudinal study conducted in 109 pALS. VF evaluations contained 10 barium trials spanning three International Dysphagia Diet Standardisation Initiative (IDDSI) levels (0-7). Duplicate, independent, and blinded ratings were completed. DIGESTV2 Efficiency and Safety grading was then completed under two conditions-with and without the inclusion of moderately thick liquid bolus trials into DIGESTV2 grading-to produce two sets of DIGESTV2 ratings for each VF study. Descriptives, percent agreement, and a weighted Cohen's kappa were performed on DIGESTV2 grades. A total of 373 VF examinations were included in this analysis. DIGESTV2 grade percent agreement with and without IDDSI Level 3 was excellent for Safety (98.1%), Efficiency (93.8%), and Total (94.1%) grades. Kappa values for Safety, Efficiency, and Total grades were .96, .89, and .91, respectively, indicating excellent agreement across bolus trial inclusion methods. Standard inclusion of moderately thick liquid bolus trials did not significantly impact DIGESTV2 grading in this data set. These results add to the preliminary but growing evidence suggesting stability of DIGEST grading with alternate bolus protocols in another patient population. https://doi.org/10.23641/asha.32348451.\n\nID: 42202251\nTitle: Beyond Time Saved: Implementation, Equity, and the Utility Threshold for Nursing AI Scribes.\nAbstract: Schwabe et al's pre-post time-motion study of a domain-specific artificial intelligence (AI) speech assistant used by nurses in German long-term care provides one of the few real-world, full-shift evaluations of an AI scribe deployed to a nonphysician workforce, with paired objective observation and self-reported outcomes. This commentary points to the implications of these findings that extend well beyond the time savings headline. The study reports substantial reduction in self-reported documentation time and increased satisfaction with the documentation system, yet workplace satisfaction and the perception that AI scribes are \"a good idea to implement\" did not improve. Taken together, these findings show three undertheorized issues for AI scribe implementation in nursing and long-term care. First, postimplementation increases in time spent reviewing entries and retrieving information indicate that AI scribes redistribute cognitive effort from authoring to verification, with unknown consequences for satisfaction, mastery, and error detection. Second, the apparent paradox of rising documentation satisfaction alongside falling expectations of AI quality represents user calibration. Third, the substantial equity considerations of automatic speech recognition documentation reflect a broader trend of AI scribe studies that treat equity as a caveat, rather than treating equitable performance as empirically measurable and testable across variations in linguistic styles, dialects, and social linguistic dimensions. To advance the field, the next generation of nursing AI scribe research must treat documentation as a heterogeneous bundle of authoring, reviewing, retrieving, and verifying activities with distinct satisfaction and error profiles; specify and validate end-user-defined anchor utilities, rather than having a narrow focus on diffuse improvement; and treat equity testing and reporting of both automatic speech recognition systems and workforce adoption as standard reporting expectations, rather than caveats.\n\nID: 42191539\nTitle: Discovering Hidden Vocal Subtypes: An Unsupervised Acoustic-Biomechanical Exploration of Voice Profiles.\nAbstract: This study aims to explore latent acoustic-biomechanical patterns of voice production using an unsupervised multivariate approach, and to identify data-driven vocal profiles across individuals with amyotrophic lateral sclerosis (ALS) and nonneurological dysphonia. A cross-sectional sample of 100 individuals, including patients with ALS and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders.\n\nID: 42167272\nTitle: Updated trends in the global prevalence and burden of mental disorders, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: The 2023 iteration of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) estimated prevalence, incidence, and health burden for 375 diseases and injuries, including 12 mental disorders. We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100 000 population, and age-standardised rates per 100 000 population. We estimated 1·17 billion (95% uncertainty interval 1·06-1·31) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14 210·7 cases (12 849·5-15 940·1) per 100 000 population. These estimates represented a 95·5% (75·0-121·2) increase in prevalent cases and 24·2% (11·4-41·4) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070·5 DALYs (1519·1-2750·5) per 100 000 population. Mental disorders contributed to 6·1% (4·8-7·6) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17·3% (14·8-20·6) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239·6 [1643·7-3014·1] per 100 000) than among males (1900·2 [1399·8-2510·8] per 100 000), and peaked in the 15-19 years age group (2617·3 [1850·6-3696·8] per 100 000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302·4 (952·7-1683·7) per 100 000 in Viet Nam to 3555·8 (2661·9-4715·0) per 100 000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853·0 (1352·1-2469·3) per 100 000 for middle SDI to 2184·1 (1606·1-2890·3) per 100 000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required. Additionally, we need more coordinated and inclusive policies to reduce the burden through early treatment and prevention, tailored to sex and age differences across locations. Responding to the mental health needs of our global population, especially those most vulnerable, is an obligation, not a choice.

We aimed to characterize the clinical phenotype, upper motor neurone (UMN) sign prevalence, survival, and functional milestones. We retrospectively analyzed 78 patients with ALS8 confirmed via molecular testing or familial linkage analysis from 57 apparently unrelated families. UMN signs were assessed using a five-item composite of pyramidal signs. Survival and milestones were estimated using Kaplan-Meier analysis. Median age at onset was 44.9 years; 51% were men. Onset was lumbar in 94%, proximally predominant. UMN signs were present in 53 patients; none exhibited clonus. At admission, 51% had spinal-onset ALS, 42% progressive muscular atrophy (PMA) and 6% flail leg; 30% of patients with PMA subsequently developed UMN signs. Survival was 21.9 years; times to wheelchair dependence and noninvasive ventilation were 7.0 and 10.0 years, respectively. Bulbar involvement occurred in 17 (21.8%) patients, predominantly as dysphonia. UMN status did not affect survival (p = 0.312). The standardized mortality ratio was 4.54 (95% CI 2.77-7.01), supporting disease-related excess mortality. ALS8 is a slowly progressive motor neurone disease with lumbar onset, ascending progression, and frequent but subtle UMN signs. Survival was markedly prolonged but functional decline followed a predictable sequence. These findings expand the phenotypic characterization of ALS8 and support genetic counseling and anticipatory management.\n\nID: 42152867\nTitle: The effects of a mobile healthcare application on speech and swallowing in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) impairs oral motor function, negatively affecting patients' speech and swallowing abilities, as well as quality of life. This study aims to evaluate the effectiveness of A Successful Swallowing with Effortful Training (ASSET) program, included in the 'The 365 Healthy Swallow Health Coach application' in preserving speech and swallowing abilities in ALS patients through self-training. In this 8-week quasi-experimental study, 13 participants were allocated to either the app-guided ASSET training group (n=7; three sessions per day, five days per week) or a usual-care control group (n=6) based on their clinical visit schedules. To evaluate changes over time and compare the two groups, linear mixed models were employed. Changes in ALS severity scale (ALSSS), Diadochokinetic (DDK) task, speech intensity, Speech Handicap Index-15, Dysphagia Handicap Index, Swallowing Quality of Life (SWAL-QOL), and Brief Inventory of Swallowing Assessment-15 were assessed. ALSSS speech scores was relatively preserved from 5.43 (95% CI 3.01-7.84) to 5.29 (95% CI 2.87-7.70) in the ASSET treatment group, but declined from 6.33 (95% CI 3.73-8.94) to 4.83 (95% CI 2.23-7.44) in the control group, with a significant group-by-time interaction (p=.017). DDK/tuh/and/kuh/were relatively preserved from 11.86 to 11.71 and from 12.29 to 11.57 respectively in ASSET group, but declined from 11.67 to 7.50 and from 11.83 to 7.17 in the control group, with significant interactions in/tuh/(p=.032) and/kuh/(p=.044). SWAL-QOL total score was relatively preserved from 155.86 to 149.71 in ASSET group, but declined from 154.67 to 125.17 in the control group, with a significant interaction (p=.011). The findings suggest that ASSET program may help preserve speech and swallowing function in patients with ALS. Future research should validate the ASSET program with a larger, adequately powered sample size.\n\nID: 42151746\nTitle: Perceptions of Speech-Language Pathology Care in Amyotrophic Lateral Sclerosis: A Patient-Centered Exploratory Study.\nAbstract: Given limited research on patient perspectives of speech-language pathology (SLP) services in ALS care, this study aimed to assess the satisfaction with, and understanding of, SLP services by people with ALS (pwALS) and to examine the alignment between services received and patient-reported impairments. A cross-sectional survey assessing pwALS' perceptions of SLPs was distributed from October 2024 to January 2025 through electronic mailing lists of relevant professional organizations. A questionnaire examined pwALS' understanding of the SLP role, satisfaction levels, alignment between patient-reported impairments and SLP interventions, and perceived gaps in care. Responses were analyzed using descriptive statistics, with open-ended items analyzed using qualitative analysis. The 81 survey respondents consisted of pwALS (81.5%), caregivers (11.1%), family members (4.9%), and others (2.5%). Overall satisfaction with SLP care was high, though open-ended responses revealed gaps in understanding. Many were unaware of the full scope of SLP services; only 17.3% recognized cognitive evaluation and 8.6% cognitive therapy, compared with speech (77.8%) and swallowing (81.5%) evaluations. Reported services often did not align with communication and swallowing needs, but patients educated about a service were significantly more likely to use it. Overall satisfaction with SLP care was high; however, open-ended responses revealed gaps in understanding, unmet needs, and limited awareness of the full scope of SLP services. This misalignment highlights the need for improved patient and caregiver education regarding the role and timing of SLP involvement to enhance engagement, appropriate service use, and outcomes in ALS care.\n\nID: 42137113\nTitle: An interpretable, clinically grounded framework for digital speech biomarker development in neurodegenerative diseases.\nAbstract: Communication ability-a key determinant of quality of life-is frequently affected and progressively declines in neurodegenerative diseases. Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.\n\nID: 42385017\nTitle: Understanding patients' experiences and needs around decision-making for bulbar symptom management at a multidisciplinary ALS clinic.\nAbstract: This study explored the decision-making experiences of people living with amyotrophic lateral sclerosis (ALS) for managing bulbar symptoms and their perceived needs for decision-making support from healthcare professionals. An interpretive, descriptive qualitative study was conducted. We recruited adult patients with ALS with and without any bulbar symptoms from a multidisciplinary ALS clinic in Central Canada. Patients were interviewed using a semi-structured guide. Reflexive thematic analysis was used to analyze study data. Recruitment ceased when information power was reached. Twelve participants were interviewed. Three themes were identified for patient's decision-making experiences and needs: (1) Disease uncertainty hinders decision-making; (2) Quality information triggers decision-making; and (3) Personal values and beliefs inform decision-making. To reduce psychological consequences of disease uncertainty and complexity on bulbar-related decision-making, patients emphasized the need for specific and contextualized information and healthcare professional supports aligned with their decision-making styles and approaches, highlighting the importance of a person- and family-centred approach to ALS care. Patients with amyotrophic lateral sclerosis (ALS) experience uncertainty with bulbar disease progression and interventions, which hinders both conversations and decisions about intervention.Patients want healthcare professionals to provide information about how intervention options and intervention timing were tailored to their individual situations.Patients also want healthcare professionals to adapt their communication and guidance to patients’ decision-making styles and approaches.Attention to patient’s broader social context is needed for decision-making to support person- and family-centred ALS care.Findings highlight the need for more healthcare professional education and research to improve decision-making support in a multidisciplinary ALS clinic setting.\n\nID: 42361332\nTitle: Patient-Reported Symptom Burden in Individuals With Parkinson Disease.\nAbstract: To better understand Parkinson disease (PD) burden and advance the clinical management of patients, it is important to ascertain the most significant symptoms directly from individuals with PD. This research used patient-reported data to identify the most prevalent and impactful symptoms experienced by individuals with PD and determine the demographic and clinical characteristics that are associated with higher symptomatic burden. We conducted semistructured qualitative interviews of 20 individuals with self-reported PD, obtaining 2,978 quotes regarding potential symptoms of importance. Findings from these interviews informed the development of a cross-sectional survey study designed to asess the impact of these symptoms in a larger cohort. Four-hundred four participants with self-reported PD participated in the survey study, providing the prevalence and relative importance (0-4 scale) of 301 symptoms representing 14 symptomatic themes. We subsequently performed subgroup analysis to identify demographic and clinical characteristics that were associated with a higher prevalence of symptomatic burden in PD. The most prevalent symptomatic themes identified by participants were sleep disturbances and daytime sleepiness (87.0%) and fatigue (84.7%). The symptomatic themes with the greatest impact (0-4) on participants' lives were fatigue (1.34) and sleep disturbances and daytime sleepiness (1.29). A higher prevalence of disease burden across all symptomatic themes was most strongly associated with speech impairment, gait freezing, and a duration of tremor greater than 5 years. The impact of PD on the lives of those living with this disease is multisystemic, reaching beyond the cardinal motor symptoms. Fatigue, sleep disturbances, and daytime sleepiness are highly prevalent and important to this population.\n\nID: 42351263\nTitle: Dynamic integration of skeletal muscle signals via extracellular vesicles in motor neuron diseases.\nAbstract: Extracellular vesicles (EVs) are heterogenous lipid bilayer-enclosed particles secreted by virtually all cell types. They encapsulate a diverse array of bioactive molecules, including proteins, lipids, nucleic acids, and metabolites, which can be transferred to recipient cells, thereby modulating their function and phenotype. In recent years, skeletal muscle-derived EVs (SkM-EVs) have emerged as key players in the bidirectional communication between skeletal muscle and motor neurons, contributing to the establishment and maintenance of neuromuscular homeostasis. Disruptions in this intercellular signalling have been implicated in the pathophysiology of motor neuron diseases (MNDs) such as spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS). In these contexts, SkM-EVs may contribute to disease progression by delivering pathogenic cargo, including misfolded proteins and aberrant RNAs, to motor neurons. A comprehensive understanding of SkM-EV biology, particularly their roles in neuromuscular communication, could offer critical insights into disease mechanisms and identify novel opportunities for biomarker discovery and therapeutic intervention. This review synthesizes current knowledge on the functional roles of SkM-EVs in motor neuron health and disease and evaluates their potential as diagnostic tools and therapeutic vectors in the context of MNDs.\n\nID: 42298083\nTitle: The lung-brain axis in neurodegeneration: inflammatory, immune, and vascular mechanisms with therapeutic implications.\nAbstract: Neurodegenerative and chronic pulmonary diseases represent major global health challenges and have widely been investigated separately. Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions.\n\nID: 42285406\nTitle: Recent advances in neurodegenerative diseases therapeutics: The inhibition of monoacylglycerol lipase strategy.\nAbstract: Neurodegenerative diseases share common pathophysiological mechanisms, including chronic neuroinflammation, glutamatergic excitotoxicity, oxidative stress, mitochondrial dysfunction, and disruptions in synaptic and lipid homeostasis. In this context, the endocannabinoid system has emerged as a key modulator of neuroimmune communication and neuronal survival. Within this system, Monoacylglycerol Lipase (MAGL) plays a central role by regulating the levels of the endocannabinoid 2-Arachidonoylglycerol (2-AG) while simultaneously contributing to the generation of arachidonic acid and pro-inflammatory eicosanoids. Pharmacological or genetic inhibition of MAGL increases 2-AG levels and concurrently reduces the biosynthesis of pro-inflammatory lipid mediators, thereby modulating microglial activation, astrocytic responses, and neuronal excitotoxicity. Preclinical studies in models of Alzheimer's disease, Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis consistently demonstrate that MAGL blockade attenuates neuroinflammation, preserves synaptic and neuronal integrity, improves motor and cognitive function, and, in some cases, delays disease progression. Although clinical evidence remains limited, the available data position MAGL as a metabolic convergence point between inflammation and neurodegeneration, suggesting that its modulation may represent a therapeutic strategy with disease-modifying potential.\n\nID: 42269975\nTitle: Progressive choroid plexus enlargement across disease stages in patients with sporadic amyotrophic lateral sclerosis.\nAbstract: The choroid plexus (CP), a key structure involved in cerebrospinal fluid homeostasis and glymphatic function, is increasingly recognized as an interface for neuroimmune communication. Recent studies have identified CP abnormalities as potential neuroimaging markers in several neurodegenerative disorders, including sporadic amyotrophic lateral sclerosis (sALS). However, whether CP enlargement occurs early and progresses across clinical stages or over time in patients with sALS remains unclear. Given the role of the CP in peripheral-central nervous system immune crosstalk, the association between neuroinflammation and CP abnormalities in sALS also requires clarification. In this prospective study, we used structural MRI to examine cross-sectional and longitudinal CP volume changes in patients with sALS and to evaluate their associations with CSF inflammatory markers. This prospective study included 161 newly diagnosed patients with sALS who underwent genetic testing and structural MRI, and 64 healthy controls (HCs) who underwent structural MRI. Disease stage in patients with sALS was assessed using the King's staging system. Longitudinal MRI was performed in a subset of 42 patients, of whom 38 also underwent baseline CSF inflammatory protein assessment. Compared with HCs, patients with sALS at all King's stages showed significantly larger CP volumes after Bonferroni correction (all p < 0.05). CP volumes were significantly greater in patients at King's stage 3 than in those at King's stage 1 or stage 2 after Bonferroni correction (all p < 0.05). In the longitudinal subgroup, CP volume increased significantly from baseline to follow-up. Multivariable analysis showed that higher CSF CHIT1 and IL-6 levels were independently associated with larger CP volume in patients with sALS (β = 0.348-0.456; p < 0.01). Our findings provide evidence that CP enlargement occurs early and progresses across disease stages and over time in patients with sALS. Higher CSF CHIT1 and IL-6 levels were associated with larger CP volume, supporting a potential link between neuroinflammation and CP abnormalities in sALS. These findings support CP enlargement as a promising neuroimaging marker for monitoring disease progression and neuroinflammatory processes in patients with sALS.\n\nID: 42236740\nTitle: HeyJay! A corpus of atypical speech for spoken language understanding and automatic speech recognition.\nAbstract: Speech technologies, such as automatic speech recognition or spoken language understanding, are not usually adapted to atypical speech, i.e., the speech of people with dysarthria, dysphonia, or another type of speech impairment. That prevents atypical speakers from leveraging speech assistants or other human-machine-interaction-powered platforms, which could make their lives easier or increase their independence. In this article, we present HeyJay!, a new corpus of atypical speech in English language from participants with neurodegenerative disorders, including Parkinson's Disease, or Amyotrophic Lateral Sclerosis. The current corpus version comprises 8,669 utterance recordings, including supervised transcriptions and intent annotations. In this study, we demonstrate the validity of the corpus by applying it to automatic speech recognition, spoken language understanding, and data augmentation tasks. Additionally, the dataset includes speech quality ratings for each participant, performed by expert speech and language pathologists. This corpus, the first one with intent annotation of atypical speech that is publicly available, is intended to create more fair speech technologies for atypical speakers by adapting and improving the state of the art, and to facilitate further research in the field.\n\nID: 42113599\nTitle: Amyotrophic Lateral Sclerosis: A Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord. It affects approximately 25 000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants.\n\nID: 41981045\nTitle: Speech-based digital endpoints track ALS progression and align with standard clinical outcomes: evidence from the VRG50635 trial.\nAbstract: We report on the utility of speech-based digital endpoints measured during a Phase 1b study of VRG50635 in Amyotrophic Lateral Sclerosis (ALS). Fifty-four participants with ALS were enrolled and participated in an 8-week pretreatment run-in, followed by three 8-week dosing periods and an 8-week follow-up. They completed a speech assessment every two weeks in the clinic or at home. We observed moderate to high correlations between digital measures of speech timing and articulatory motor function, and the ALS Functional Rating Scale-Revised, slow vital capacity and plasma neurofilament light chain. Furthermore, speech measures can show functional decline before the ALSFRS-R does, while also capturing differences between participants with bulbar symptoms and those without. The results support the feasibility and utility of digital speech endpoints to study disease impact in ALS clinical trials.\n\nID: 41928799\nTitle: Stable speech BCI performance during slow progression of ALS: A longitudinal ECoG study.\nAbstract: Electrocorticographic (ECoG) speech brain-computer interfaces (BCIs) show promise for restoring communication in amyotrophic lateral sclerosis (ALS), but the long-term stability of speech-related neural signals and decoding performance during disease progression remains unclear. We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8×8 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1×10-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC.

Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication. Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles. Additionally, lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms. Overall, lncRNAs have emerged as central molecular regulators and promising candidates for translation in NDDs. Nonetheless, challenges related to specificity, validation, delivery across the blood-brain barrier, and clinical standardization must be addressed before their routine application in precision neurology.\n\nID: 41907197\nTitle: Hereditary transthyretin amyloidosis mimicking ALS: First genetically proven case report from Saudi Arabia.\nAbstract: Hereditary transthyretin amyloidosis (ATTRv) is a systemic disorder that may mimic motor neuron disease (MND), leading to misdiagnosis and delayed access to disease-modifying therapies. We report the first genetically confirmed case of ATTRv mimicking amyotrophic lateral sclerosis (ALS) in Saudi Arabia. A 47-year-old male presented with progressive right-sided limb weakness (proximal > distal) and dysarthria over 18 months. Neurological examination revealed fasciculations, distal atrophy, and brisk reflexes with normal muscle tone and no spasticity. Electrophysiological studies demonstrated a length-dependent sensorimotor axonal neuropathy with widespread denervation changes involving bulbar, cervical, and lumbosacral regions. Brain and spine MRI, along with whole-body CT, excluded structural or paraneoplastic causes. Genetic testing identified a pathogenic heterozygous variant in the TTR gene: NM_000371.4:c.424G > A (p.Val142Ile). Transthoracic echocardiography revealed mild concentric left ventricular hypertrophy. There was no clinical evidence of autonomic, renal, or ocular involvement. This case underscores the importance of considering ATTRv in patients presenting with atypical MND, particularly when clinically significant sensory symptoms, absent upper motor neuron signs, or unexplained cardiac abnormalities are present. Early diagnosis enables access to targeted therapies such as TTR stabilizers and gene-silencing agents, which can alter disease trajectory.\n\nID: 41905645\nTitle: Six months of experience at a specialized daytime care center for people with amyotrophic lateral sclerosis (ALS) in the Community of Madrid.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects motor neurons, leading to motor deterioration and a reduced quality of life. In the Community of Madrid, the ALS Network was established to improve patient care. In April 2024, the Specialised Day Care Centre for ALS (CEADELA) was inaugurated, complementing the care provided by the ALS Network. The aim of this study was to describe the experience of CEADELA during its first six months. A retrospective descriptive study was conducted on a cohort of CEADELA patients between April and October 2024. Clinical, functional, and therapeutic data were analysed, along with overall satisfaction levels. A total of 91 patients were included, with a mean age of 65.2 years (SD 11); of these, 59 (64.8%) were men. Most had spinal-onset ALS and were receiving treatment with riluzole. A significant increase was observed in the use of physiotherapy, speech therapy, and occupational therapy after referral to the centre. Functionality significantly declined over six months. The mortality rate was 12.1% (18.2% opted for assisted dying). Overall, 76 patients (83.5%) responded to the survey, with 100% reporting satisfaction or high satisfaction with the centre (80.2% very satisfied and 18.4% satisfied). CEADELA has improved access to specialised therapies with a high level of satisfaction, although disease progression remains a challenge. The need to continue developing integrated, evidence-based care models to optimise ALS management is highlighted.\n\nID: 41827952\nTitle: Motor Neuron Disease with Guillain-Barré Syndrome? Motor Band Sign with Anti-GQ1b Antibodies.\nAbstract: A 79-year-old former marathoner, with memory impairment since age 78, developed increasing stumbling and progressively worsening waddling gait. Three months after gait disturbance onset, she noted mild dysphagia. With declining walking distance and endurance, she presented to our hospital six months after onset, exhibiting frontal signs, Parkinsonism with marked trunk rigidity, and hyperreflexia of the jaw and limbs. L-dopa challenge tests showed no improvement. At seven months post-onset, she had difficulty rising. By nine months, she relied on a walker, and speech disturbance appeared. At 10-11 months, both dysarthria and dysphagia rapidly worsened, she became bed-ridden, and upper limb weakness developed (though she could still use chopsticks). Neurological examination at one year revealed severe dysarthria/dysphagia, four extremity fasciculations and muscle weakness (grade 2 in upper limbs, grade 1 in lower limbs), trunk-dominant rigidity, and hyperreflexia in the jaw and limbs. Brain MRI, specifically susceptibility-weighted imaging, revealed motor band signs. Cerebrospinal fluid study revealed albuminocytological dissociation. Needle electromyography revealed acute denervation and chronic reinnervation in the cranial nerve, cervical, and lumbar areas, which was suggestive of motor neuron disease (MND). Serum anti-GQ1b antibodies were detected. Immunotherapy was followed by mild improvement, which might suggest a reversible component, although definitive pathological overlap remains unconfirmed. This case highlights a diagnostic challenge where an acute immune-mediated neuropathy could potentially be superimposed on a chronic neurodegenerative process. Anti-GQ1b antibodies should be interpreted with caution, as they may reflect either a true clinicopathological overlap with Guillain-Barré syndrome or a secondary phenomenon (epiphenomenon) related to the primary neurodegenerative process.\n\nID: 41784486\nTitle: Exploring the use of narrative-based approaches in individuals with amyotrophic lateral sclerosis: A narrative review.\nAbstract: Narrative-based approaches have been utilized in medicine to better understand the illness experiences of individuals living with chronic conditions. In particular, people with amyotrophic lateral sclerosis (pALS) may benefit from use of narrative-based approaches, given the potential impact of progressive decline on identity of self. This review explores the use of narrative-based approaches in studies involving pALS to provide further insight to the experiences and psychosocial needs of this population. A search was conducted utilizing EMBASE, CINAHL, PsycInfo, and Google Scholar with several terms related to amyotrophic lateral sclerosis (ALS) and narrative-based approaches. Studies were included if they were written in English, incorporated methods that promoted the production of narratives, and reported data that could be clearly isolated to pALS. The search revealed a total of 154 articles for title and abstract screening. Fifty-two articles were selected for full-text review. Thirty-two articles met the criteria for data extraction. Four descriptive categories emerged upon examination of the narrative-based approaches implemented across the studies: psychosocial intervention, illness experience, intervention targeting specific needs, and secondary analysis of data. Some of the common themes identified across studies included: loss of physical and communicative function, adaptation to life changes, shifts in identity, and tension with the healthcare system. Despite the communication challenges that often coincide with disease progression, narrative-based approaches can be utilized in pALS. These approaches should be implemented to gain insight on the disease experiences of pALS, providing opportunity for patient-centered interventions to address the psychosocial needs of this population.\n\nID: 41744765\nTitle: The Calcium Connection: Explaining Motor Neuron Vulnerability in ALS.\nAbstract: ALS is a severe neuromuscular disease classically characterized by the progressive loss of motor neurons, leading to incremental muscle weakness and eventually death. Current treatment options for ALS have proven to have limited effect, merely delaying the progression of symptoms and prolonging patient survival. This motor neuron subtype-related differential vulnerability has been linked to neuron excitability, metabolism, and protein aggregation. Calcium dysregulation, which serves as an important second messenger in neural signaling pathways, has been implicated in each of these mechanisms and represents a potential target for therapeutic intervention. Armed with cutting-edge tools for visualizing and recording calcium transients in vivo, ALS researchers have delved deeper into the role of calcium dysregulation in disease in recent years. Vulnerable motor neuron populations display an excess of calcium-permeable ion channels together with reduced expression of calcium-binding proteins, generating a cellular environment primed for excitotoxic stress. Loss of inhibitory synaptic input further heightens susceptibility to calcium overload. Paradoxically, some evidence suggests that elevated neuronal activity can exert neuroprotective effects, highlighting the complexity of activity-dependent calcium signaling in ALS. Additionally, ALS-related toxic protein accumulation disrupts calcium homeostasis, contributing to endoplasmic reticulum stress and mitochondrial dysfunction. Emerging data indicate that calcium dysregulation impairs neuron-glia communication, amplifying neuroinflammation and accelerating disease progression. This review aims to synthesize current evidence on how calcium imbalance contributes to motor neuron vulnerability and degeneration in ALS. By exploring the cellular, synaptic, and network-level mechanisms of calcium dysregulation in ALS, the review examines its interplay with mitochondrial and ER stress and explores its impact on neuron-glia interactions with the aim of synthesizing key mechanistic insights into the disease pathogenesis and therapeutic targets.\n\nID: 41663537\nTitle: [Relatives in the context of assisted dying: challenges and support needs].\nAbstract: The decision to pursue physician-assisted dying can place a significant emotional burden on relatives. Despite the considerable psychosocial stress they often face, these individuals have received limited attention in research, clinical practice and ethical or societal debates surrounding this topic. This article provides an overview of the role of relatives in the context of physician-assisted dying.Previous studies indicate that relatives are frequently confronted with moral dilemmas, ambivalent emotions and anticipatory grief. In addition, they often take on organisational responsibilities in support of the person wishing to die and may experience stigma and subsequent social isolation. Research also suggests that relatives and close friends are at increased risk for mental health challenges.At the same time, certain aspects of the process, such as the opportunity to say goodbye, open communication and the active involvement of relatives, can have a positive effect and support a more adaptive grieving process. These findings highlight the importance of psychosocial support for relatives as well as the necessity of involving them at an early stage throughout the entire process. Die Entscheidung für einen assistierten Suizid kann für Angehörige mit erheblichen emotionalen Belastungen einhergehen. Trotz der vielfältigen psychosozialen Herausforderungen finden Angehörige in Forschung, Versorgung sowie in ethischen und gesellschaftlichen Diskursen zu diesem Thema bislang nur unzureichende Beachtung. Der vorliegende Artikel bietet einen Überblick über die Rolle der Angehörigen im Kontext des assistierten Suizids.Bisherige Studien zeigen, dass Angehörige häufig mit moralischen Dilemmata, ambivalenten Emotionen sowie antizipatorischer Trauer konfrontiert sind. Darüber hinaus übernehmen sie oftmals organisatorische Aufgaben zur Unterstützung der sterbewilligen Person und erleben nicht selten Stigmatisierung sowie daraus resultierende soziale Isolation. Zudem deuten bisherige Studienergebnisse darauf hin, dass Angehörige ein erhöhtes Risiko für die Entwicklung psychischer Erkrankungen aufweisen können.Gleichzeitig können bestimmte Merkmale des assistierten Suizids entlastend auf Angehörige wirken und die Verarbeitung des Verlusts positiv beeinflussen. Hierzu zählen unter anderem die Möglichkeit zur Abschiednahme, offene Kommunikation sowie die Einbindung in den Prozess des assistierten Suizids. Diese Befunde unterstreichen die Notwendigkeit spezifischer psychosozialer Unterstützungsangebote für Angehörige sowie deren frühzeitige Einbindung in relevante Prozesse.\n\nID: 41511908\nTitle: Utility of Simple Speech Measures in Amyotrophic Lateral Sclerosis Assessment: Focus on Alternating Motion Rate as a Screening Tool.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive degeneration of motor neurons. Early detection of bulbar symptoms is crucial for timely diagnosis and intervention; however, variability in symptom progression complicates clinical assessment. This retrospective observational study aimed to classify patients with ALS into three groups - spinal onset, spinal onset with bulbar involvement, and bulbar onset - and to identify speech evaluation metrics that effectively differentiate these groups. Data from 68 patients with ALS were retrospectively analyzed. Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making.\n\nID: 41500873\nTitle: Voice-Based Prediction of Survival in Amyotrophic Lateral Sclerosis (ALS) Patients Using Biomechanical Acoustic Markers.\nAbstract: To evaluate whether voice-derived acoustic and biomechanical features can serve as non-invasive biomarkers for mortality-risk prediction and survival stratification in patients with amyotrophic lateral sclerosis (ALS). We conducted a retrospective study including 50 ALS patients evaluated in a phoniatrics consultation with available sustained vowel recordings, demographic data, and functional assessments. Nested logistic regression models were developed to predict clinical outcomes, progressively incorporating demographic variables, functional indices (Grade, Roughness, Breathiness, Asthenia, Strain, and Barthel), acoustic features (fundamental frequency, jitter, shimmer, harmonics-to-noise ratio), and biomechanical voice parameters (Pr1-Pr22). Model performance was assessed using receiver operating characteristic curves and area under the curve (AUC) comparisons via DeLong tests. Stepwise Akaike Information Criterion (StepAIC) was applied to optimize the final model. A Cox proportional hazards model was used to evaluate the association between voice parameters and survival time. The final StepAIC model, which included a subset of biomechanical features, achieved excellent predictive performance (AUC = 0.903, 95% confidence interval: 0.816-0.989), significantly outperforming baseline and acoustic-only models. Bootstrapping confirmed the model's robustness and generalizability. Cox regression analysis showed that the derived risk scores stratified patients into tertiles with significantly different survival probabilities (log-rank P < 0.0001; hazard ratio for high vs. low-risk group = 11.2). Biomechanical voice features are strong predictors of mortality in ALS and outperform traditional clinical and acoustic indices. These findings support the integration of voice analysis into ALS monitoring protocols as a non-invasive, cost-effective, and scalable prognostic tool.\n\nID: 41488323\nTitle: Sigma receptors and mitochondria-associated ER membranes are converging therapeutic targets for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) begins decades before clinical symptoms emerge. The \"amyloid hypothesis\" suggests that amyloid-β (Aβ) deposition initiates a cascade of tau hyperphosphorylation, neuroinflammation, and neuronal loss leading to cognitive decline. The recent success of anti-Aβ therapies such as Leqembi in prodromal or mild cognitive impaired patients underscores the importance of early intervention and Aβ clearance. However, safety and cost limitations highlight the need for alternative therapeutic strategies. Small-molecule modulators of Sigma-1 and Sigma-2 receptors (σ1R and σ2R) have emerged as promising candidates for AD treatment. σ1R agonists exhibit neuroprotective and anti-amnestic effects under pathological conditions without affecting normal cognition. Beyond AD, σ1R is implicated in several neurodegenerative diseases including ALS (amyotrophic lateral sclerosis), Parkinson's, and Huntington's diseases, stroke, and epilepsy. σ1R plays a key role at mitochondria-associated ER membranes (MAMs)-specialized lipid raft-like domains that form functional membrane contact sites between the endoplasmic reticulum (ER) and mitochondria. β-secretase (BACE1), γ-secretase, and their substrates APP and palmitoylated APP (palAPP) localize in the MAMs, promoting amyloidogenic Aβ production. MAMs serve as dynamic hubs for inter-organelle communication, calcium signaling, and lipid metabolism. The \"MAM hypothesis\" proposes that MAM dysregulation drives early AD pathology and persists throughout disease progression, contributing to neurofibrillary tangle formation, calcium imbalance, and neuroinflammation. This review aims to summarize the current understanding of σ1R-mediated regulation of MAMs and its neuroprotective mechanisms, highlighting potential therapeutic opportunities for targeting σ1R in AD and other neurodegenerative disorders.\n\nID: 41467443\nTitle: Mitochondria-associated endoplasmic reticulum membranes and calcium ion exchange: A novel direction for aging and neurodegenerative diseases.\nAbstract: Mitochondria-associated endoplasmic reticulum membranes serve as crucial signaling hubs mediating communication between the endoplasmic reticulum and mitochondria, and play a central role in calcium ion exchange. This dynamic interface regulates key cellular processes including bioenergetic metabolism, apoptosis, autophagy, and stress responses. Dysregulation of calcium transport associated with mitochondria-associated endoplasmic reticulum membranes can disrupt intracellular homeostasis, leading to mitochondrial dysfunction, oxidative stress, and neuronal death, which are hallmarks of aging and neurodegenerative diseases. This review systematically examines the functions of protein complexes within mitochondria-associated endoplasmic reticulum membranes and the pathogenic mechanisms of calcium signaling regulated by these membranes in neurodegenerative disorders. It places particular emphasis on structural alterations in calcium ion transport machinery as a common mechanism underlying various neurodegenerative diseases. In Alzheimer's disease, mitochondria-associated endoplasmic reticulum membranes exhibit a hyperactive state, promoting the generation of amyloid-β and enhancing calcium ion flux from the endoplasmic reticulum to the mitochondria. In contrast, in Parkinson's disease and amyotrophic lateral sclerosis, the activity of mitochondria-associated endoplasmic reticulum membranes is reduced, leading to a decline in mitochondrial calcium ion buffering capacity and exacerbating excitotoxicity. Proteins residing in mitochondria-associated endoplasmic reticulum membranes are disrupted across various neurodegenerative diseases, resulting in abnormal communication between the endoplasmic reticulum and mitochondria. Recent studies indicate that mitochondria-associated endoplasmic reticulum membranes play a bidirectional role in disease progression, and compensatory mechanisms often exacerbate the pathological process. Therapeutic strategies aimed at preserving the integrity of mitochondria-associated endoplasmic reticulum membranes hold promise for alleviating neurodegenerative damage. Therefore, calcium ion exchange mediated by mitochondria-associated endoplasmic reticulum membranes plays a key role in aging and neurodegenerative diseases, making it a highly promising therapeutic target.\n\nID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.\n\nID: 42369228\nTitle: Talking about the hypothetical future: Serious illness communication for residents living with dementia in long-term care homes - An integrative review.\nAbstract: In long-term care (LTC) homes, residents living with dementia frequently experience serious illness communication that is crisis-initiated and oriented to institutional documentation (e.g., transfer and resuscitation orders), rather than iterative, values-based discussions aligned with a palliative approach and substitute decision-making frameworks. Unpaid care partners often make high-stakes decisions with limited preparation, and residents are inconsistently included. To explore how serious illness communication occurs with residents living with dementia, unpaid care partners, and healthcare providers in LTC, and to identify practice-relevant communication strategies and contextual factors applicable to clinical practice. An integrative review following Toronto and Remington's six-stage methodology included 31 high-relevance studies (qualitative, quantitative, mixed methods, reviews, theoretical) published from 2015 to 2025 on serious illness, goals-of-care, or end-of-life communication in LTC dementia care. Directed content analysis was guided by Tarbi et al.'s basic science of communication in serious illness (lexical, non-lexical, contextual elements, and outcomes). Serious illness communication was predominantly biomedical and documentation-focused, often occurring at admission or during crises and directed mainly to unpaid care partners, with limited resident involvement. Lexical practices such as clear, jargon-free information, explicit invitations to discuss \"what matters most,\" and early conversations about hypothetical future scenarios enhanced trust, preparedness, and alignment of care with resident values. Non-lexical elements (tone, eye contact, pacing, use of silence) shaped perceived empathy but were seldom explicitly addressed by interventions. For LTC healthcare providers, embedding earlier, iterative serious illness communication, explicitly involving residents where possible, and cultivating both lexical and non-lexical skills are key to achieving relationship-centred, legally compliant, and goal-concordant palliative approaches to care.​. This review looked at how people talk about serious illness and end-of-life care with residents living with dementia in long-term care (LTC) homes, and how these conversations affect care decisions. Serious illness communication includes discussions about what matters most to residents as their dementia progresses, what kinds of treatments they would or would not want, and how unpaid care partners and healthcare providers can prepare for future changes and dying. The review found that these conversations in LTC usually happen late in the illness, often during admission to an LTC home or during a crisis and focus mainly on medical decisions or paperwork (for example, hospital transfer forms or resuscitation status). Residents with dementia are often not included directly and most conversations are held with unpaid care partners, who can feel unprepared or distressed. How healthcare providers communicate (by tone of voice, eye contact, body language, and use of silence) can strongly influence whether families feel heard, respected, and able to trust the team. The way LTC homes are organized also shapes these conversations. Staffing levels, continuity of staff, time pressures, leadership support, and charting systems all influence whether serious illness discussions are ongoing and person-centred, or brief, checklist-style tasks. When communication works well, unpaid care partners report better understanding of what to expect, more confidence in making decisions, and care that is better aligned with the resident’s values near the end-of-life.\n\nID: 42360421\nTitle: [Prevention instead of remediation-screening, lifestyle factors, and prostate care 2.0-transition of urology to healthcare coach : Holistic approach to prostate health].\nAbstract: Establishment of an organized, risk-adapted prostate cancer screening program in Germany could serve as a key entry point for preventive men's health. How can the introduction of an organized, risk-adapted prostate cancer screening program in Germany shape preventive urology of the future? This narrative review article is based on guidelines and expert consensus supported by a literature search in PubMed. The cited studies represent the most relevant work on this topic and were selected to illustrate developments and fundamental concepts; however, completeness is not claimed. Serum prostate-specific antigen (PSA) levels and prostate MRI not only identify patients at increased risk for prostate cancer but also offer insights into other urological conditions, such as lower urinary tract symptoms and hypogonadism. In analogy to other early detection strategies, PSA testing at the age of 45-50 years could serve as a simple triage test to guide risk-adapted follow-up and timely referral to urological care. Lifestyle factors-including regular physical activity, a balanced diet, and pelvic floor training-may favorably influence urological health and related outcomes. While organized prostate cancer screening has already been shown to improve cancer-specific mortality to a level comparable to mammography, a more holistic approach may further enhance its overall benefit. Urology has significant opportunities to actively promote healthy behaviors among aging men. The establishment of an organized prostate cancer screening program provides an ideal entry point for this purpose. Modern screening concepts should incorporate holistic health promotion for aging men alongside direct oncological endpoints. HINTERGRUND: Die Etablierung einer organisierten, risikoadaptierten Prostatakarzinomfrüherkennung könnte Grundlage einer präventiven Männergesundheit sein. Wie kann die Einführung einer organisierten, risikoadaptierten Prostatakarzinomfrüherkennung die präventive Urologie von morgen prägen? Dieser narrative Übersichtsartikel auf der Grundlage von Leitlinien und Expertenkonsens wird unterstützt durch eine Literaturrecherche auf PubMed (2000–2026). Die zitierten Studien stellen nach Meinung der Autoren die relevanten Arbeiten hierzu dar und wurden ausgewählt, um Entwicklungen und prinzipielle Konzepte zu veranschaulichen, beanspruchen jedoch keine Vollständigkeit. Der PSA-Wert (prostataspezifisches Antigen) und die MRT liefern nicht nur Hinweise auf ein Prostatakarzinom, sondern auch auf andere urologische Erkrankungen wie Miktionsbeschwerden oder Testosteronmangel. Parallel zu anderen Früherkennungsuntersuchungen könnte der PSA-Wert mit 45–50 Jahren als einfaches Triage-Tool fungieren, um risikoadaptierte Verlaufskontrollen sowie fachurologische Vorstellungen zu steuern. Lebensstilfaktoren wie Bewegung, eine gesunde Ernährung und Beckenbodentraining können urologische Erkrankungen und deren Folgen positiv beeinflussen. Durch eine organisierte Prostatakarzinomfrüherkennung kann das karzinomspezifische Mortalität bereits heute vergleichbar zur Mammographie verbessert werden, durch ein holistischeres Herangehen kann der Gesamtnutzen jedoch noch mehr gesteigert werden. Die Urologie hat große Chancen, die Gesundheitskompetenz des alternden Mannes, aber auch Früherkennungsmaßnahmen für andere Erkrankungen, aktiv zu fördern. Die organisierte Prostatakarzinomfrüherkennung könnte hierfür einen sinnvollen Einstieg darstellen. Moderne Früherkennungskonzepte sollten die ganzheitliche Gesundheitsförderung des alternden Mannes neben direkten onkologischen Endpunkten miteinbeziehen.\n\nID: 42276630\nTitle: Accreditation as opportunity: Preparing future nursing leaders through faculty collaboration and succession planning.\nAbstract: Preparing for Commission on Collegiate Nursing Education (CCNE) accreditation requires extensive faculty engagement, yet the literature offers limited guidance on operational strategies to cultivate collaboration and mentorship during this process. This article describes the Keigwin School of Nursing's adaptation of Benner's novice to expert framework and Haverkamp et al.'s (2018) \"map for accreditation\" to design a collaborative approach for developing the self-study report and preparing for a site visit. Junior faculty were paired with experienced mentors in dyads, assigned to analyze key elements of the CCNE Standards, and reported findings back to cross-program Standard Teams. This structure fostered faculty development, enhanced understanding of accreditation processes, and promoted succession planning. Standardized meeting minutes, end-of-year committee reports, and the use of stoplight tracking tools provided systematic evidence of continuous quality improvement. Faculty-wide meetings and individualized support further strengthened readiness and confidence for site visit engagement. The outcome was full faculty participation, successful alignment of undergraduate and graduate program reaccreditation cycles, and no accreditation compliance concerns reported for any program. These results underscore the value of mentorship, collaboration, and succession planning in accreditation preparation and highlight the potential to address national challenges in faculty shortages, destabilization of higher education, and the need for a unified nursing faculty voice in academic advocacy.\n\nID: 42273832\nTitle: Remote, self-administered, smartphone cognitive testing in a registry-based cohort: Feasibility, reliability, and validity findings.\nAbstract: Remote, smartphone-based cognitive testing may improve access to cognitive assessments for Alzheimer's disease and related dementias. We evaluated the feasibility, reliability, and validity of unsupervised smartphone-based cognitive tests in a registry-based cohort. Adults without a record of cognitive impairment (N = 1815; ages 18-92) were recruited from the University of California, San Francisco (UCSF) Brain Health Registry to complete three unsupervised smartphone cognitive testing sessions within 2 weeks. Reliability was assessed with correlations between sessions. Linear regression models tested associations of smartphone tasks with demographics, self- and informant-rated cognitive concerns, and web-based cognitive testing (Cogstate Brief Battery). Adherence was high (82.2%) and usability favorable. Test-retest reliability was moderate to strong (ρ's = 0.61-0.85, all p's < 0.001). Lower smartphone scores were associated with older age, lower education, cognitive concerns, and worse Cogstate performance. Findings support the feasibility, reliability, and validity of remote digital assessments in adults without a record of cognitive impairment.\n\nID: 42204548\nTitle: Putative glymphatic dysfunction links extracellular fluid dysregulation to white matter degeneration and clinical impairment in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron degeneration and prominent extra-motor involvement. Impaired clearance of neurotoxic proteins has led to increasing interest in the brain glymphatic system; however, its in vivo associations with brain microstructure and clinical heterogeneity remain incompletely understood. One hundred forty-six patients with ALS and 149 demographically matched healthy controls (HCs) underwent multimodal MRI and comprehensive clinical assessments. Putative glymphatic function was quantified using diffusion tensor imaging along perivascular space (DTI-ALPS). Extracellular free water fraction (FWF) and free-water-corrected fractional anisotropy (fwcFA) were derived to characterize extracellular fluid and white matter microstructure. Group differences were assessed using vertex-wise and voxel-wise analyses with correction for multiple comparisons. Associations among imaging metrics and clinical measures were evaluated using correlation and serial mediation analyses. Compared with HCs, patients with ALS exhibited significantly reduced DTI-ALPS index, widespread increases in cortical FWF, bidirectional alterations in white matter FWF, and extensive reductions in fwcFA across major white matter tracts. Reduced DTI-ALPS was associated with changes in extracellular free water and white matter microstructural integrity, whereas FWF and fwcFA measures were associated with functional, cognitive, and emotional outcomes. Mediation analyses identified significant indirect associations between DTI-ALPS and both functional and cognitive measures through a pathway involving cortical FWF, white matter FWF, and fwcFA, although direct associations were not observed. These findings provide in vivo evidence that putative glymphatic dysfunction co-occurs with extracellular fluid alterations, white matter microstructural changes, and clinical impairment in ALS. Multi-compartment diffusion imaging may offer complementary markers for characterizing brain microstructure and its clinical relevance in ALS.\n\nID: 42201356\nTitle: [Hereditary breast cancer : Syndromes, pathology, clinical aspects].\nAbstract: Approximately 5-10% of all breast cancers arise from a hereditary predisposition. In addition to the high-risk genes BRCA1 and BRCA2, other genes involved in homologous recombination repair (including PALB2, ATM, CHEK2, RAD51C/D, BARD1) and genes associated with classic tumor predisposition syndromes (TP53, PTEN, STK11, CDH1, NF1) are associated with an increased risk of breast cancer. In addition, polygenic risk contributes to the individual probability of developing the disease through the additive effect of numerous low-penetrance variants.Pathology can contribute significantly to the identification of patients with possible hereditary tumorigenesis. Certain morphological and immunohistochemical features may indicate a genetic background-for example, a lymphocyte-rich, triple-negative phenotype, G3, with medullary features may indicate a BRCA1 mutation, or an invasive lobular carcinoma may indicate a CDH1 mutation. Clinical constellations such as early age of onset, bilateral tumors, associated tumors, or familial clustering are also important indicators.The identification of a germline mutation has far-reaching consequences for the affected individual and the entire family. Intensive follow-up care programs are offered to those affected; risk-reducing surgery may be considered for mutations in certain risk genes. There are also therapeutic implications, such as the use of PARP inhibitors in BRCA1/2-associated HER2-negative breast cancer. Predictive genetic testing may be considered for relatives as well as intensified early detection programs and risk-reducing surgery, if necessary.Close interdisciplinary cooperation is therefore crucial in order to identify patients with possible hereditary tumorigenesis at an early stage and to enable an individualized therapy and follow-up care strategy. Etwa 5–10 % aller Mammakarzinome entstehen auf dem Boden einer hereditären Prädisposition. Neben den Hochrisikogenen BRCA1 und BRCA2 sind weitere Gene der homologen Rekombinationsreparatur (u. a. PALB2, ATM, CHEK2, RAD51C/D, BARD1) sowie Gene klassischer Tumorprädispositionssyndrome (TP53, PTEN, STK11, CDH1, NF1) mit einem erhöhten Brustkrebsrisiko assoziiert. Darüber hinaus trägt ein polygenes Risiko durch die additive Wirkung zahlreicher niedrigpenetranter Varianten zur individuellen Erkrankungswahrscheinlichkeit bei.Die Pathologie kann wesentlich zur Identifikation von Patientinnen mit möglicher hereditärer Tumorgenese beitragen. Bestimmte morphologische und immunhistochemische Merkmale können auf einen genetischen Hintergrund hinweisen – etwa ein lymphozytenreicher, triple-negativer Phänotyp, G3, mit medullären Eigenschaften auf eine BRCA1-Mutation oder ein invasives lobuläres Karzinom auf eine CDH1-Mutation. Auch klinische Konstellationen wie frühes Erkrankungsalter, bilaterale Tumoren, assoziierte Tumoren oder familiäre Häufung sind wichtige Hinweise.Die Identifikation einer Keimbahnmutation hat weitreichende Konsequenzen für die Betroffene sowie die gesamte Familie. Betroffenen werden intensivierte Nachsorgeprogramme angeboten. Bei Mutationen in bestimmten Risikogenen kommen risikoreduzierende Operationen in Betracht. Zudem ergeben sich therapeutische Implikationen, etwa der Einsatz von PARP-Inhibitoren bei BRCA1/2-assoziierten HER2-negativen Mammakarzinomen. Für Angehörige kommen prädiktive genetische Untersuchungen infrage sowie ggf. intensivierte Früherkennungsprogramme und risikoreduzierende Operationen.Die enge interdisziplinäre Zusammenarbeit ist entscheidend, um Patientinnen mit möglicher hereditärer Tumorgenese frühzeitig zu identifizieren und eine individualisierte Therapie- und Nachsorgestrategie zu ermöglichen.\n\nID: 42187452\nTitle: Assessment of Respiratory Rate and Simulated Apnea Utilizing the PneumoWave Biosensor: In Vitro and In Vivo Validation.\nAbstract: Accurate monitoring of respiratory rates is critical for early detection of a range of clinical conditions. However, standard manual counting or inadequate clinical monitoring often fails to provide reliable measurements. This study evaluated and validated the PneumoWave biosensor for respiratory rate measurement across a broad physiological range and different body postures (45°, 90°, and 180°) in both in vitro and in vivo settings. In vitro validation was performed using a SimMan ALS manikin operated at respiratory settings of 6-30 breaths per minute, with 10 s periods of simulated apnea. In vivo validation involved 20 healthy volunteers performing metronome-guided breathing while wearing bilateral PneumoWave biosensors. In vitro results demonstrated an excellent correlation between biosensors and manikin respiratory settings and captured all apnea events (r = 0.99, ICC = 0.99). In vivo findings showed good agreement with direct observational count (r = 0.99, R2 = 0.99, ICC = 0.99), with 97% of apnea events captured by both devices in all positions. Body postures had no significant impact on biosensor accuracy. These findings demonstrate that the PneumoWave biosensor provides accurate and reliable respiratory monitoring and supports its potential as a robust, non-invasive tool for continuous clinical and remote patient monitoring.\n\nID: 42420060\nTitle: Development of a target product profile for artificial intelligence in diabetic eye screening in England: a modified Delphi consensus study.\nAbstract: Artificial intelligence (AI) health-care technologies offer a means of addressing the growing gap between health-care capacity and demand. However, few technologies have met the complex requirements of health-care systems for adoption. Diabetic eye screening (DES) in England exemplifies the difficulty of understanding these requirements and translating them into real-world implementation decisions. This Review responds to a recognised policy need to develop a target product profile (TPP) for a DES AI system for use in England. The TPP outlines the requirements of the English health-care system for such a device and was developed using a modified Delphi consensus process involving interviews, surveys, and a consensus meeting. Participants included people living with diabetes, health-care professionals, health-care managers and leaders, regulators and policy makers, and developers. Thirty-five product specifications were agreed upon, covering areas such as clinical validity, utility, and environmental sustainability. Our TPP establishes clear criteria for DES AI development and deployment in England, and this TPP development process can serve as a template for initiatives to create TPPs for other AI health technologies and settings.\n\nID: 42410270\nTitle: [The digital patient journey in radiological emergencies : Massive hemoptysis as a stress test of interoperability].\nAbstract: Massive hemoptysis is a life-threatening emergency in which the risk of asphyxiation predominates over blood loss. The situation becomes particularly challenging when a patient must be transferred from an external facility and clinically relevant information is incomplete. The initial diagnostic workup already begins prior to transfer to a specialized center. Initial priorities are oxygenation, correct patient positioning, and early airway protection. Depending on the local infrastructure, computed tomography (CT) angiography and bronchoscopy are the preferred modes of imaging. Structured, digital transfer of information, results, and imaging data without loss of data is paramount. In peripheral or systemic bleeding, bronchial artery embolization is the first-line therapeutic option and should be performed at a specialized center. A superselective technique, strict nontarget prevention, and adherence to established standard operating procedure (SOP) principles are essential. Massive hemoptysis is an example for the digital patient journey in radiological emergencies: when preliminary diagnostics are performed at an external hospital and definitive treatment is provided at a specialized center, the structured and rapid transfer of clinical information to that center is critical for quality of treatment. Emergency datasets on the electronic health card, the electronic patient record, and technical standards (FHIR, DICOM, and DICOMweb) are clinically relevant. European infrastructures (MyHealth@EU, European Health Data Space) may support the future of structured access to key clinical information and direct exchange of imaging data; however, they have not yet been fully integrated into routine emergency radiological practice. In radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component. It improves data triage, reduces media discontinuity, and may help prevent unnecessary repeat imaging. In radiological emergencies, it must be assessed at an early stage whether further treatment in an interventional center is necessary. In these cases, relevant data and clinical information should be transferred in a structured and fully digital manner without loss of information. KLINISCHES PROBLEM: Massive Hämoptyse zählt zu den vital bedrohlichen Situationen in der Notfallmedizin, da primär die Asphyxiegefahr und erst nachrangig der Blutverlust im Vordergrund steht. Besonders herausfordernd sind Versorgungssituationen außerhalb des gewohnten Behandlungskontexts, etwa wenn ein Patient in ein Zentrum verlegt werden muss und relevante Informationen nicht vollständig vorliegen. Die initiale Diagnostik beginnt bereits außerhalb eines spezialisierten Zentrums. Vorrang haben Oxygenierung, korrekte Lagerung, Absaugmanagement und eine niedrige Schwelle zur Atemwegssicherung. Je nach lokaler Infrastruktur können erste bildgebende und endoskopische Maßnahmen, insbesondere Computertomographie(CT)-Angiographie und Bronchoskopie, erfolgen. Eine strukturierte und verlustfreie Übermittlung von Vorinformationen, Befunden und Bilddaten ist entscheidend. Die definitive Versorgung massiver Hämoptysen mit bronchialer oder nichtbronchial-systemischer Blutungsquelle sollte in einem Zentrum mit entsprechender Expertise erfolgen. Die Bronchialarterienembolisation stellt die etablierte First-Line-Therapie dar. Entscheidend sind eine superselektive Katheterisierung, die Vermeidung von Non-Target-Embolisationen sowie die Beachtung standardisierter sicherheitsrelevanter Standard-Operating-Procedures (SOP). Damit wird die massive Hämoptyse zu einem exemplarischen Fall für die digitale Patientenreise im radiologischen Notfall: Wenn initiale Diagnostik und definitive Therapie an unterschiedlichen Versorgungsorten stattfinden, ist ein strukturierter und rascher Transfer klinischer Informationen für die Behandlungsqualität unmittelbar relevant. DIGITALE INFRASTRUKTUR UND INTEROPERABILITäT: Heute sind vor allem der Notfalldatensatz auf der elektronischen Gesundheitskarte, die elektronische Patientenakte sowie etablierte technische Standards (FHIR, DICOM, DICOMweb) praxisrelevant. Europäische Infrastrukturen (MyHealth@EU, European Health Data Space) eröffnen darüber hinaus eine wichtige Zukunftsperspektive für den grenzüberschreitenden und standardisierten Austausch klinischer Informationen und Bilddaten, befinden sich jedoch noch nicht in einer flächendeckend etablierten notfallradiologischen Routine. Interoperabilität ist im radiologischen Notfall keine rein technische Zusatzfunktion, sondern sicherheitsrelevante Infrastruktur. Sie verbessert die Datentriage, reduziert Medienbrüche und kann eine unnötige wiederholte Bildgebung vermeiden. EMPFEHLUNG FüR DIE PRAXIS: Im radiologischen Notfall ist frühzeitig zu prüfen, ob eine Weiterbehandlung in einem interventionellen Zentrum erforderlich ist. Dafür sollten relevante Daten und klinische Informationen strukturiert und möglichst medienbruchfrei übermittelt werden.\n\nID: 42407013\nTitle: Role of the Upper Motor Neuron in the Generation of Fasciculations in Early Disease Stages of Amyotrophic Lateral Sclerosis.\nAbstract: The origin of fasciculation potentials (FPs) in the early stages of amyotrophic lateral sclerosis (ALS) remains a subject of debate. We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders.\n\nID: 42394053\nTitle: Use and Usability of Wearable Devices in Assistive Living: A Scoping Review.\nAbstract: This paper describes a scoping review that explored the use and usability of wearable devices in assistive living with a focus on barriers to the real-world use of this technology in the home for the elderly. Published research was reviewed from the databases: PubMed, CINAHL, IEEE Xplore, and Web of Science. Using Arksey's et al.'s scoping review methodology relevant studies were identified, resulting in 37 reviewed for thematic analysis. The thematic analysis resulted in specific themes to barriers and facilitators in usability. Themes include privacy and security, technical challenges, providing a sense of safety and continued independence, and knowing connection to support is available if required. Wearable technology can positively contribute to elder care but a number of key issues and barriers remain.\n\nID: 42393685\nTitle: Structural-functional network decoupling in early stage amyotrophic lateral sclerosis reveals cell-type specific transcriptional signatures.\nAbstract: Amyotrophic lateral sclerosis (ALS) involves widespread brain network dysfunction, yet the molecular mechanisms linked to these alterations remain poorly understood. We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology.\n\nID: 42389895\nTitle: Nanoscale morphological and structural analysis of round and donut oligomers formed by C-terminal domain of TDP-43.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), Alzheimer's disease (AD), limbic predominant age-related TDP-43 encephalopathy (LATE), and Parkinson's disease are associated with an abrupt aggregation of TAR DNA-binding protein 43 (TDP-43). Although molecular mechanisms of this pathological aggregation remain unclear, accumulated evidence suggests that the C-terminus domain (C-terminal domain (CTD)) is the trigger of TDP-43 self-assembly into toxic oligomers and fibrils. While the secondary structure and morphology of protein fibrils have been well documented, very little is known about TDP-43 oligomers. This is primarily because of the transient nature and low concentrations of these protein species. In the current study, we utilize nano-infrared spectroscopy, also known as atomic force microscopy-infrared (AFM-IR) spectroscopy, to investigate the morphology and secondary structure of CTD of TDP-43 oligomers formed at the early and middle stages of protein aggregation. This innovative technique allows us to resolve both morphology and secondary structure of individual protein aggregates. We found that at the early stage of protein aggregation, CTD of TDP-43 formed two morphologically different protein aggregates: donut-like (DO) and round (RO) oligomers. DO yielded fibrillar species, while RO persisted throughout the entire course of CTD TDP-43 self-assembly.\n\nID: 42387528\nTitle: Fidelity in the context of adapting a digital intervention for depression from an evidence-based in-person format in Vietnam.\nAbstract: Digital interventions have emerged as a promising way to better meet growing population mental health needs. Our team developed a digital depression intervention (VMood; smartphone app) in Vietnam. VMood is adapted from an evidence-based in-person intervention (SSM) developed in Canada and uses cognitive behaviour therapy (CBT) principles with remote coaching by non-specialist providers. Fidelity-adaptation is a major tension in implementation science. Fidelity is the degree an intervention is designed and delivered as intended. Conversely, adaptations are sometimes made for specific contexts. This paper aims to identify key elements of fidelity-adaptation - the degree VMood is consistent theoretically with the SSM intervention and practically with implementing digitally in the Vietnamese setting. This study uses Perez et al.'s modified version of Carroll et al.'s Implementation Fidelity Framework, focusing on Objective 1: Conceptualizing what intervention fidelity means in this specific context (across modes and cultures) and Objective 2: Conducting fidelity testing to identify key elements along the fidelity-adaptation continuum. Ethnographic data from team meetings explored essential components that must remain intact and necessary adaptations. Non-specialist providers and app users from Vietnam tested VMood. Experts familiar with CBT provided theoretical feedback. Interviews or focus groups were conducted with all participants to gain insights into the adaptive intervention. Qualitative data were analyzed using thematic content analysis. Participants agreed that VMood captures the essential theoretical components from SSM, noting certain elements of SSM (e.g., change in human contact to online) could not be replicated digitally. Participants also presented adaptation suggestions unique for the digital format to strengthen VMood's acceptability, including keeping the app simple by reducing the amount of text; incorporating more dynamic content (e.g., animations) to increase engagement; and including more culturally appropriate scenarios. Finally, key potential moderators to fidelity reported included quality of program delivery and participant responsiveness. Findings identified intervention specific elements of fidelity-adaptation and showed that VMood retained essential components of SSM while incorporating adaptations to support implementation within the Vietnamese context. With the global increase in digital health services adapted from in-person delivery, understanding how to balance fidelity with necessary adaptations is important both theoretically and practically.\n\nID: 42379229\nTitle: [Stimulating Interest, Opening Up Perspectives: A Bathing Water Inspection as an Extracurricular Activity to Attract Young Doctors to the Public Health Service - Pilot Project with Evaluation].\nAbstract: The public health service (ÖGD) has had little presence in human medicine studies in Germany to date. As a result, students lack knowledge about its practical tasks, meaning that the ÖGD is rarely considered when choosing a career. This situation contributes significantly to the shortage of young doctors in public health departments. Elective placements during the practical year are intended to attract students to the ÖGD; however, evaluations indicate that the offered places are not being filled, despite the positive assessment. Project description To promote interest in the ÖGD at an early stage and in a low-threshold manner, an extracurricular course was developed at Justus-Liebig-Universität Gießen as a supplementary elective in the interdisciplinary area of Health Economics, Health System, and Public Health. In the summer semester of 2025, a 90-minute bathing water inspection was held for the first time in cooperation with the Giessen Health Authority. The aim was to provide students with practical insights into the work of the ÖGD in the fields of water and environmental hygiene, while also establishing personal contact with the authorities' employees. Feedback from participants showed that the event was found to be enriching both professionally and in terms of career orientation. In contrast to clinical placements or PJ elective terms, the format allowed for very low-threshold access without requiring students to choose between other subject areas. Extracurricular elective courses such as bathing water inspections can serve as a complementary strategy to raise students' awareness of the ÖGD at an early stage and thus contribute to the long-term recruitment of young talent to public health service. Der Öffentliche Gesundheitsdienst (ÖGD) hat im Humanmedizinstudium bislang eine geringe Präsenz. Dadurch fehlt es Studierenden an Kenntnissen über seine praktischen Aufgaben, sodass der ÖGD bei der Berufswahl kaum berücksichtigt wird. Diese Situation trägt wesentlich zur ärztlichen Nachwuchslücke in den Gesundheitsämtern bei. Wahltertiale im Praktischen Jahr sollen Studierende für den ÖGD gewinnen, doch Auswertungen zeigen, dass die angebotenen Plätze nicht ausgeschöpft werden, obwohl die Evaluationen positiv ausfallen. Projektbeschreibung Um das Interesse am ÖGD frühzeitig und niederschwellig zu fördern, wurde an der Justus-Liebig-Universität Gießen ein extracurriculares Lehrangebot als ergänzendes Wahlangebot zum Querschnittsbereich 3 Gesundheitsökonomie, Gesundheitssystem und Öffentliches Gesundheitswesen entwickelt. Im Sommersemester 2025 fand erstmals eine 90-minütige Badegewässerbegehung in Kooperation mit dem Gesundheitsamt Gießen statt. Ziel war es, Studierenden praxisnah Einblicke in die Arbeit des ÖGD im Bereich Wasser- und Umwelthygiene zu ermöglichen und gleichzeitig den persönlichen Kontakt zu Mitarbeitenden der Ämter herzustellen.Die Rückmeldungen der Teilnehmenden zeigen, dass die Veranstaltung sowohl fachlich als auch in Hinblick auf die Berufsorientierung als bereichernd empfunden wurde. Im Unterschied zu Famulaturen oder PJ-Wahltertialen ermöglicht das Format einen sehr niederschwelligen Zugang, ohne dass Studierende sich gegen andere Fachgebiete entscheiden müssen.Extracurriculare Wahlangebote wie die Badegewässerbegehung können als ergänzende Strategie dienen, Studierende frühzeitig für den ÖGD zu sensibilisieren und damit langfristig zur Nachwuchsgewinnung beizutragen.\n\nID: 42360520\nTitle: Comments on: Predictors of pathologic complete response in early-stage triple-negative breast cancer treated with neoadjuvant chemo-immunotherapy.\nAbstract: This correspondence comments on LeVee et al.'s real-world study of neoadjuvant chemo-immunotherapy in early-stage triple-negative breast cancer. We highlight diabetes as a potentially modifiable host-state factor influencing pathologic complete response and propose a metabolic immunotherapy-readiness framework integrating glycaemic control, treatment delivery, endocrine monitoring, and equity-focused implementation. This perspective aims to support globally applicable strategies for improving chemo-immunotherapy effectiveness and access.\n\nID: 42341745\nTitle: [Digital transformation in multiple sclerosis: Advances in diagnostics, monitoring and patient-centred care].\nAbstract: Digital transformation is fundamentally changing the diagnosis, monitoring and treatment of multiple sclerosis. The integration of multimodal data from imaging, laboratory tests, clinical assessments, patient-reported outcomes and continuous measurements via wearables is creating high-resolution, longitudinal profiles of disease progression. Based on this data, modern analysis methods and artificial intelligence enable predictive models for disease activity, progression and therapeutic response, supporting personalised decision-making. Digital patient pathways and patient portals open up new options for participatory, standardised care, while telemedicine, telerehabilitation and digital health applications complement care regardless of location and time. In research, real-world data, federated learning and virtual, decentralised studies are accelerating patient-centred evidence generation. Concepts such as the digital twin outline the next stage of development in simulation-based precision medicine. Key challenges relate to data protection and data security, data quality, interoperability, bias, transparency and the traceability of algorithmic decisions. Overall, digitalisation offers substantial opportunities to detect disease activity earlier, optimise treatment goals and improve quality of life and care - provided that technical, regulatory and ethical requirements are consistently addressed and translated into scalable care models. Die digitale Transformation verändert Diagnostik, Monitoring und Therapie der Multiplen Sklerose grundlegend. Durch die Integration multimodaler Daten aus Bildgebung, Labor, klinischen Assessments, patientenberichteten Ergebnissen sowie kontinuierlichen Messungen via Wearables entstehen hochauflösende, longitudinale Profile des Krankheitsverlaufs. Auf dieser Datengrundlage ermöglichen moderne Analyseverfahren und Künstliche Intelligenz prädiktive Modelle zur Krankheitsaktivität, Progression und Therapieantwort und unterstützen personalisierte Entscheidungswege. Digitale Patientenpfade und Patientenportale eröffnen neue Optionen für partizipative, standardisierte Versorgung, während Telemedizin, Telerehabilitation und digitale Gesundheitsanwendungen die Betreuung orts- und zeitunabhängig ergänzen. In der Forschung beschleunigen Real-World-Daten, föderiertes Lernen und virtuelle, dezentralisierte Studien patientenzentrierte Evidenzgenerierung. Konzepte wie der digitale Zwilling skizzieren die nächste Entwicklungsstufe einer simulationsgestützten Präzisionsmedizin. Zentrale Herausforderungen betreffen Datenschutz und Datensicherheit, Datenqualität, Interoperabilität sowie Bias, Transparenz und Nachvollziehbarkeit algorithmischer Entscheidungen. Insgesamt bietet die Digitalisierung substanzielle Chancen, Krankheitsaktivität früher zu erkennen, Therapieziele zu optimieren und die Lebens- und Versorgungsqualität zu verbessen – vorausgesetzt, dass technische, regulatorische und ethische Voraussetzungen konsequent adressiert und in skalierbare Versorgungsmodelle überführt werden.\n\nID: 42320585\nTitle: [Professional Health Literacy within the Academic Transition of Midwifery Education: Findings from a Quantitative Study of Midwifery Students in Germany].\nAbstract: Since 2020, midwifery has been the first health profession in Germany to be fully transferred into academic education. However, it remains unclear whether midwifery students acquire the professional health literacy required to meet the increasing challenges of the healthcare system, such as the substantial growth in available specialized knowledge and the evolving expectations of patients regarding care and participation in decision-making. Whether and how future midwives possess the necessary competencies to respond to these new challenges is reflected in their level of professional health literacy. The aim of this study is therefore to assess the current status of professional health literacy among students of midwifery science. Data collection was conducted as part of the HELPER study. A total of 140 midwifery students from Bavaria were included. Professional health literacy was measured using the PROF-HL-Q instrument, which comprises 34 items covering four domains. Results are presented descriptively. Correlation analyses were performed to identify potential associations with sociodemographic characteristics and study-related parameters. On average, students rated their professional health literacy positively, achieving scores between 51.4 and 78.7 out of 100 across the four domains. Patient-centered communication was perceived as the easiest domain, whereas professional digital health literacy was rated the most challenging. In particular, students reported difficulties in interpreting statistical results, dealing with misinformed patients, and supporting patients in finding digital health information. Overall, only weak correlations were observed with the variables examined. The findings indicate specific areas in which midwifery students' competencies require further strengthening and thus provide implications for curriculum development, particularly in light of ongoing digitalization and the continued professionalization of midwifery. Der Hebammenberuf ist seit 2020 der erste Gesundheitsfachberuf in Deutschland, der vollständig in die Akademisierung überführt wurde. Allerdings ist unklar, ob die angehenden Hebammen durch das Studium auch die notwendige professionelle Gesundheitskompetenz vermittelt bekommen, um den steigenden Herausforderungen des Gesundheitswesens begegnen zu können – etwa dem enormen Zuwachs an verfügbarem Fachwissen oder den veränderten Versorgungs- und Mitbestimmungsansprüchen von Patient/-innen. Ob und wie die nun angehenden Hebammen über die notwendigen Voraussetzungen verfügen, auf neue Herausforderungen des Gesundheitswesens reagieren können, wird durch die sogenannte professionelle Gesundheitskompetenz erfasst. Das Ziel der vorliegenden Arbeit ist es daher, den Status Quo der professionellen Gesundheitskompetenz von Studierenden der Hebammenwissenschaft aufzuzeigen.Die Erhebung erfolgte im Rahmen der HELPER-Studie. Es wurden 140 Hebammenstudierende aus Bayern eingeschlossen. Ermittelt wurde die professionelle Gesundheitskompetenz anhand des Erhebungsinstruments PROF-HL-Q, welches aus 34 Items besteht und vier Aufgabenbereiche umfasst. Die Ergebnisse werden deskriptiv dargestellt. Im Anschluss werden Korrelationsanalysen durchgeführt, um mögliche Zusammenhänge mit soziodemographischen Merkmalen und studienbezogenen Parametern zu identifizieren.Im Durchschnitt schätzen die Studierenden ihre professionelle Gesundheitskompetenz als positiv ein und erreichen in den vier Aufgabenbereichen zwischen 51,4 und 78,7 von 100 möglichen Punkten. Dabei fällt den Hebammenstudierenden die patientenzentrierte Kommunikation am leichtesten und die professionelle digitale Gesundheitskompetenz am schwersten. Besonders schwer fällt ihnen das Einordnen statistischer Ergebnisse, der Umgang mit falschinformierten Patient/-innen sowie die Unterstützung von Patient/-innen beim Finden digitaler Gesundheitsinformationen. Insgesamt zeigen sich nur geringe Korrelationen mit den getesteten Bezugsgrößen.Die Ergebnisse geben Hinweise darauf, in welchen Bereichen die Kompetenzen der Hebammenstudierenden noch gestärkt werden müssen und lassen somit Schlussfolgerungen für die Gestaltung der Lehrcurricula zu, besonders mit Blick auf die fortschreitende Digitalisierung und die weitere Professionalisierung des Hebammenberufes.\n\nID: 42318821\nTitle: 3D-printed lab-on-chip platforms for the detection of neurodegenerative diseases: opportunities and challenges.\nAbstract: Neurodegenerative diseases (NDs) such as Alzheimer's, Parkinson's, and ALS remain some of the most challenging disorders to diagnose at an early stage. Conventional approaches rely on costly neuroimaging or invasive cerebrospinal fluid sampling, which limit accessibility and early intervention. Recent advances in 3D printing have enabled rapid prototyping of lab-on-chip (LOC) platforms that integrate microfluidics, biosensors, and biological models to detect disease-specific biomarkers with high sensitivity and throughput. Herein, we explore the synergistic role of 3D printing technologies and biomaterials in fabricating LOC systems for NDs. We highlight key biomarkers, and neuron- and organoid-on-chip platforms, and discuss the challenges and opportunities in clinical translation. By combining technical innovation in additive manufacturing with biological relevance, 3D-printed LOC devices represent a transformative approach toward precision diagnostics in neuro-medicine.\n\nID: 42310450\nTitle: A mosaic of whole-body representations on the human precentral gyrus.\nAbstract: Understanding how the body is represented in the motor cortex is key to understanding how the brain controls movement. Although the motor cortex has been mapped in animal models at a fine scale1-10, characterization in humans remains primarily limited to low-resolution recording11-16 and stimulation techniques17-20. Here we created a comprehensive map of the human motor cortex at single-neuron resolution, spanning microelectrode array recordings from 20 arrays across 8 individuals with paralysis from spinal cord injury, amyotrophic lateral sclerosis or brainstem stroke, all enrolled in brain-computer interface clinical trials. These arrays broadly sample the crown of the precentral gyrus (PCG; thought to be composed largely of the premotor cortex (Brodmann area 6)). We found that body parts were highly intermixed, such that the entire body was represented in all sampled locations of the PCG, although the relative strength of body parts was roughly consistent with the motor homunculus17,18. We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them. Throughout the PCG, movement representations of the four limbs were interlinked, with homologous movements of different limbs (for example, toe curl and hand close) having correlated representations. These data provide evidence consistent with an intermixed, interrelated and behaviour-centred organization of the motor cortex3,21. The resulting map also provides important targeting information for brain-computer interfaces that seek to restore motor function.\n\nID: 42293321\nTitle: Quantitative susceptibility mapping reveals widespread brain iron abnormalities in sporadic patients with early-stage amyotrophic lateral sclerosis.\nAbstract: In the present study, using the novel quantitative susceptibility mapping technique, we aimed to systematically investigate brain iron alterations in a large group of sporadic early-stage amyotrophic lateral sclerosis patients and their correlation with clinical disability. In this study, amyotrophic lateral sclerosis patients at King's stage 1 were defined as early-stage amyotrophic lateral sclerosis patients, and 53 newly diagnosed early-stage amyotrophic lateral sclerosis patients and 50 healthy controls were included. Voxel-based whole-brain quantitative susceptibility mapping analysis was used to explore brain iron alterations. Voxel-based morphometry analysis was also performed. Longitudinal follow-up was performed in amyotrophic lateral sclerosis patients, and the follow-up progression rate was calculated. We found that, compared with healthy controls, early-stage amyotrophic lateral sclerosis patients presented significantly increased susceptibility values, mainly in the motor cortex, prefrontal cortex, hippocampus and cerebellar regions, while volumetric alterations were not detected. Moreover, motor and extra-motor cortex susceptibility values were significantly correlated with upper motor neuron scores and follow-up progression rate (r = 0.452-0.504, P < 0.01) in early-stage amyotrophic lateral sclerosis patients. We demonstrated a clear profile of early motor and extra-motor iron depositions and their important roles in early-stage amyotrophic lateral sclerosis patients. We suggest that quantitative susceptibility mapping is likely a promising neuroimaging approach for assessing early upper motor neuron damage and detecting early extra-motor alterations in amyotrophic lateral sclerosis patients.\n\nID: 42290559\nTitle: Integrated Analysis of hsa-miR-26b-5p and hsa-miR-186-5p in Blood Serum and Tumor Tissue Reveals their Prognostic and Predictive Significance in Breast Cancer.\nAbstract: Breast cancer (BC) heterogeneity signifi antly complicates diagnosis, prognosis, and prediction of treatment response. MicroRNAs (miRNAs) have emerged as promising biomarkers due to their involvement in tu- mor progression and in regulating therapy sensitivity. however, the combined clinical signifi ance of circulating and tumor-associated miRNAs, such as hsa-miR-26b-5p and hsa-miR-186-5p, remains insuffi    tly elucidated. Materi- als and Methods. Expression levels of hsa-miR-26b-5p and hsa-miR-186-5p were analyzed in serum and tumor tis- sue of 124 BC patients. Associations with clinicopathological parameters were assessed. The prognostic signifi ance was evaluated based on disease progression and recurrence within 3 years. The predictive value was determined in patients receiving neoadjuvant chemotherapy (4AC regimen) using response assessment and ROC analysis. Re- sults. young BC patients (≤45 years) demonstrated signifi antly lower circulating levels of both miRNAs. Serum hsa-miR-186-5p expression was associated with early-stage disease, tumor size, lymph node status, and molecular subtype. Increased circulating hsa-miR-26b-5p levels were linked to disease progression, whereas decreased hsa- miR-186-5p levels were observed in patients with unfavorable outcomes. In tumor tissue, hsa-miR-26b-5p expres- sion correlated with tumor grade, size, and metastatic status, showing elevated levels in poorly differentiated tumors and reduced expression in metastatic disease. In contrast, hsa-miR-186-5p was associated with the molecular sub- type and lymph node involvement, with the highest expression observed in hER2-positive tumors and in patients with recurrence. Elevated levels of hsa-miR-186-5p in both serum and tumor tissue were associated with reduced sensitivity to doxorubicin-based neoadjuvant chemotherapy. ROC analysis confi med its predictive value (AUC =  0.750 for serum and 0.818 for tumor tissue). No signifi ant association between hsa-miR-26b-5p and chemothe- rapy response was observed. hsa-miR-26b-5p and hsa-miR-186-5p demonstrate complementary roles in BC biology. hsa-miR-26b-5p is primarily associated with tumor aggressiveness and cancer progression, whereas hsa-miR-186-5p refl cts its molecular characteristics and response to chemotherapy. Their combined assessment in serum and tumor tissue represents a promising approach for improving prognostic stratifi ation and predicting treatment effi acy in BC patients.\n\nID: 42283699\nTitle: Supporting gastrostomy decision-making in motor neurone disease (MND): an Australian survey of healthcare professionals' beliefs, practices, and needs.\nAbstract: Gastrostomy decision-making for people living with motor neurone disease (MND) is complex. While international studies report healthcare professionals' (HCPs) beliefs and practices in this area, little is known about the Australian context. To examine Australian HCPs' beliefs, clinical practices, and support needs regarding gastrostomy decision-making in MND. A national cross-sectional online survey of Australian HCPs involved in gastrostomy discussions (n = 123) was conducted, exploring five domains: 1) initiating discussions and timing; 2) patient education; 3) multidisciplinary coordination; 4) guideline use; 5) and professional development needs. Descriptive statistics were applied. Most HCPs initiated discussions about gastrostomy (74%), commonly prompted by swallowing difficulty, weight loss, or patient request. Although 72% believed discussions should occur before clinical indications, only 40% reported doing so. Earlier placement was favored in the context of respiratory decline compared with swallowing impairment, and 56% considered gastrostomy to be performed too late. Almost 40% used no formal guidelines, and 74% wanted further professional development. Australian HCPs valued person-centered practice, but belief-practice gaps highlight opportunities to improve consistency, timing, and quality of gastrostomy decision-making support. Enhanced national guidelines, improved multidisciplinary communication, and targeted professional development may help reduce delays and better align practice with evidence-based recommendations. People living with motor neurone disease (MND) often have trouble swallowing. They may lose weight and find it hard to take medications. A feeding tube (gastrostomy) can help with food, fluids, and medication. However, deciding if and when to have a feeding tube can be difficult and emotional for people with MND and their families.Healthcare professionals play an important role in giving information and supporting these decisions. However, we do not know much about how healthcare professionals in Australia manage these discussions.In this study, we surveyed 123 Australian healthcare professionals from different fields who work with people with MND. We asked when they talk about feeding tubes, what information they give, how they work with other team members, what guidelines they use, and what training they need.Most healthcare professionals said they talk about feeding tubes when swallowing problems or weight loss begin, or when patients ask about it. Many said these conversations should happen earlier, but fewer said they actually do this. They often talked about nutrition and daily life with a feeding tube. They were less likely to talk about prognosis or the risks of waiting too long.Some healthcare professionals said communication within the care team can be difficult. Many do not use formal guidelines. Most said they would like more training, especially in decision-making and having difficult conversations.These results show ways to improve care in Australia. This includes clearer guidelines, better team communication, and more training for healthcare professionals.\n\nID: 42428129\nTitle: Association between motor cortex grey matter loss and inability to control an ECoG-based implanted Brain-Computer Interface in ALS.\nAbstract: The field of implantable Brain-Computer Interfaces (iBCIs) is rapidly advancing, with individuals with amyotrophic lateral sclerosis (ALS) as key beneficiaries. However, ALS-related cortical degeneration may impair iBCI effectiveness. This study investigated whether structural magnetic resonance imaging (MRI) and functional MRI (fMRI) metrics are associated with the quality of electrocorticography (ECoG) signals critical for iBCI use. Six late-stage ALS participants and 76 controls underwent T1-weighted structural MRI and task-based fMRI during right-hand movement or attempts thereof. ECoG data of ALS participants was benchmarked using ECoG data acquired in epilepsy patients. Grey matter thickness in the sensorimotor cortex and fMRI activation in the motor-hand area were measured. Four ALS participants showed >0.4 mm thinning in the precentral gyrus, while the postcentral gyrus was spared. ECoG signal quality was significantly associated with precentral grey matter thickness, but not with fMRI activity. These findings suggest that presurgical assessment of precentral grey matter thickness could potentially prove useful for iBCI candidate selection in advanced ALS. People with amyotrophic lateral sclerosis (ALS) can lose the ability to move and speak, but their thinking often remains intact. Implantable brain-computer interfaces (iBCIs) can help by translating brain signals into commands for communication devices. However, ALS damages the motor cortex, which may reduce the quality of these signals. In this study, we examined brain scans and electrical recordings from six people with advanced ALS. We found that thinning of the motor cortex was linked to weaker brain signals needed for iBCI control, while functional MRI activity was less predictive. This suggests that measuring motor cortex thickness before surgery could help identify who will benefit most from an iBCI, improving treatment decisions and future clinical trials. We examine presurgical MRI/fMRI and ECoG recordings from people with advanced ALS receiving implanted brain-computer interfaces. Motor cortex thinning is associated with poorer ECoG signal quality, suggesting cortical thickness may help identify candidates likely to benefit.\n\nID: 42417834\nTitle: [Far more than a dress code: more women, new leadership styles : Rethinking leadership in medicine-perspectives of the German Medical Women's Association].\nAbstract: The transformation of the healthcare system requires fundamental rethinking of medical leadership. Despite rising numbers of female physicians in both education and practice, their presence in leadership roles remains significantly underrepresented. This article examines this structural discrepancy from the perspective of the German Medical Women's Association (DÄB). It argues that gender equality is not merely a question of fairness, but a decisive factor for the quality, innovation, and sustainability of medical care. Analysis of current literature. Diverse leadership teams make more informed decisions, act with greater resilience, and demonstrably contribute to improved outcomes. Traditional role models, nontransparent selection processes, and inadequate structural conditions often prevent female physicians from gaining equal access to leadership positions. Innovative leadership and working models, such as top-level sharing, tandem structures, and part-time leadership, enhance both work-life balance and the attractiveness of medical careers. Mentoring, transparent career development, and the early promotion of leadership skills also contribute. Participation of patients, interprofessionalism, and digital skills are becoming increasingly important. The DÄB sees these developments as an opportunity to redefine leadership-as cooperative, diverse, and forward-looking. This requires structural reforms that systematically support female physicians and involve them in key decision-making processes. HINTERGRUND: Die Transformation des Gesundheitswesens erfordert ein grundlegendes Umdenken ärztlicher Führung. Trotz steigender Zahlen von Ärztinnen in Studium und Beruf ist ihre Präsenz in leitenden Positionen weiterhin deutlich unterrepräsentiert. ZIEL: Der Beitrag beleuchtet die strukturelle Diskrepanz zwischen Frauen in der Medizin i. Allg. und Frauen in Führungspositionen in der Medizin im Speziellen. Er zeigt dabei, dass Geschlechtergerechtigkeit nicht nur eine Frage der Fairness, sondern ein entscheidender Faktor für Qualität, Innovation und Zukunftsfähigkeit der medizinischen Versorgung ist. Aktuelle Literatur wurde ausgewertet. Divers zusammengesetzte Führungsteams treffen fundiertere Entscheidungen, agieren resilienter und tragen nachweislich zu verbesserten Ergebnissen bei. Dennoch verhindern tradierte Rollenbilder, intransparente Auswahlprozesse sowie strukturelle Rahmenbedingungen oftmals den gleichberechtigten Zugang von Ärztinnen zu Führungspositionen. Innovative Führungs- und Arbeitsmodelle, wie z. B. Top Sharing, Tandemstrukturen und Teilzeitführung, erhöhen sowohl die Vereinbarkeit von Beruf und Privatleben als auch die Attraktivität medizinischer Karrieren. Mentoring, transparente Karriereentwicklung und die frühzeitige Förderung von Führungskompetenzen tragen ebenfalls dazu bei. Partizipation von Patientinnen und Patienten, Interprofessionalität und digitale Kompetenzen gewinnen zunehmend an Bedeutung. Der Deutsche Ärztinnenbund e. V. (DÄB) versteht diese Entwicklungen als Chance, Führung neu zu definieren – kooperativ, divers und zukunftsorientiert. Dies erfordert strukturelle Reformen, die Ärztinnen systematisch fördern und in zentrale Entscheidungsprozesse einbeziehen.\n\nID: 42387809\nTitle: Muscle-Specific Kinase Signaling and Its Therapeutic Potential.\nAbstract: The function of the neuromuscular junction (NMJ) is compromised in many neuromuscular diseases (NMDs) such as autoimmune or congenital myasthenia gravis (MG), amyotrophic lateral sclerosis (ALS), spinal muscular atrophy (SMA), and muscular dystrophies. The NMJ contains muscle-specific kinase (MuSK), which is a critical regulator of NMJ integrity and function. Activating the MuSK signaling cascade may have therapeutic potential in several of these NMDs that are characterized by impaired neuromuscular communication. The MuSK signaling cascade consists of different components and can be activated with interventions at different levels. In the past years, different therapeutic strategies using an engineered recombinant agrin comprised of the C-terminal fragment of the protein (mini-agrin), gene therapy of key proteins in this pathway, agonist MuSK antibodies, and SRC homology 2 domain-containing phosphotyrosine phosphatase 2 (SHP2) inhibitors have been further developed for this purpose. Each of these strategies engages distinct signaling components: mini-agrin, both as recombinant protein and gene therapy, enhances agrin-Lrp4-MuSK interaction; Dok7 gene therapy amplifies MuSK phosphorylation; Lrp4 gene therapy enhances agrin responsiveness; MuSK agonist antibodies bypass upstream defects and promote downstream signaling; SHP2 inhibitors prolong the duration of active MuSK signaling. These therapeutic strategies have ameliorated NMJ integrity and function in several preclinical models of MG, motor neuron diseases, and muscular dystrophies. In this review, we highlight MuSK signaling as a possible therapeutic target, describe the therapeutic efficacy of intervention in MuSK signaling in different NMDs, and present an outlook on future clinical development.\n\nID: 42377323\nTitle: Clinical Confidence in Personality Disorder Care Requires Team-Based Formulation.\nAbstract: This letter responds to Pingani et al.'s validation of a questionnaire on clinical confidence and psychodynamic skills in personality disorder care. It argues that confidence should be interpreted at the team level, where formulation, boundaries, risk communication, and emotional containment shape the patient's experience of care.\n\nID: 42371002\nTitle: [Communication in later life under institutional conditions : Professional perspectives on communication of ageing people with profound intellectual and multiple disabilities].\nAbstract: For people with (profound) intellectual and multiple disabilities verbal language is often not the primary means of communication. Communication is closely tied to familiar persons and the interpretation of individual forms of expression. In later life health-related changes, the loss of social relationships and institutional transitions can substantially impair communication. Based on group interviews with professionals this paper examines the significance of communication partners, the professional and institutional prerequisites for successful communication in later life and the institutional embedding of augmentative and alternative communication. In this study seven group interviews were conducted with professionals working in disability support services. Data were analyzed using structured qualitative content analysis. Professionals describe social relationships in later life as fragile and communication partners as often confined to institutional settings, which increases the importance of familiar caregivers for successful communication. They further emphasize experiential and specialist knowledge, resources and knowledge transfer across interfaces. Augmentative and alternative communication appears sustainable especially where it is institutionally embedded. In later life communicative participation among this group appears less as a matter of individual competence than as an organizational and knowledge-related task: it requires both preserving biographically developed interpretive knowledge and institutionally embedded augmentative and alternative communication. HINTERGRUND: Bei Menschen mit geistiger und komplexer Behinderung ist verbalsprachliche Kommunikation häufig nicht der zentrale Kommunikationsweg. Kommunikation ist eng an vertraute Personen, Kontexte und die Deutung individueller Ausdrucksformen gebunden. Im Alter können gesundheitliche Veränderungen, Verluste sozialer Beziehungen und institutionelle Wechsel die Kommunikation beeinträchtigen. ZIEL: Der Beitrag untersucht auf Grundlage von Gruppeninterviews mit Fachkräften die Bedeutung von Kommunikationspartner:innen, professionelle und institutionelle Voraussetzungen gelingender Kommunikation im Alter sowie die institutionelle Verankerung Unterstützter Kommunikation. Es wurden sieben Gruppeninterviews mit Mitarbeitenden der Behindertenhilfe geführt. Die Auswertung erfolgte mittels strukturierender qualitativer Inhaltsanalyse. Die Fachkräfte beschreiben soziale Beziehungen im Alter als fragil und Kommunikationspartner:innen häufig als auf institutionelle Räume verengt, wodurch vertraute Bezugspersonen für gelingende Kommunikation besondere Bedeutung gewinnen. Zudem betonen sie Erfahrungswissen, Fachkenntnisse, Ressourcen sowie Kooperation und Wissenssicherung an Schnittstellen. Unterstützte Kommunikation wird vor allem dort tragfähig, wo sie institutionell verankert ist. Kommunikative Teilhabe im Alter erscheint bei diesem Personenkreis weniger als Frage individueller Kompetenz denn als organisations- und wissensbezogene Gestaltungsaufgabe: Sie verlangt sowohl die Sicherung biografisch gewachsenen Deutungswissens als auch eine institutionell verankerte Unterstützte Kommunikation.\n\nID: 42352907\nTitle: The Dual Role of Glial Extracellular Vesicles in Neurodegeneration: Insights from iPSC-Based Models.\nAbstract: Extracellular vesicles (EVs) have emerged as key mediators of intercellular communication in the brain, with glial cell-derived EVs increasingly recognized for their roles in maintaining brain homeostasis and contributing to the progression of neurodegenerative diseases. By transferring a diverse cargo of bioactive molecules, including proteins, RNAs, and organelles, EVs influence recipient cell behavior and overall brain function. In neurodegenerative conditions, glial EVs can either propagate pathogenic signals or deliver neuroprotective and regenerative cues, depending on their cellular origin and molecular composition. This context-dependent heterogeneity highlights the need for physiologically relevant human models to investigate EVs biology. Human induced pluripotent stem cell (iPSC)-derived glial models provide a disease-relevant platform, as they recapitulate key pathological features of Alzheimer's disease (AD), Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS). When further integrated with brain organoid platforms, these iPSC-based systems enable the generation of three-dimensional environments that closely resemble in vivo EVs dynamics. Importantly, glial EVs can modulate cellular pathways involved in neuronal survival and function. Indeed, their potential to interact with and, under specific experimental conditions, traverse the blood-brain barrier (BBB) has contributed to growing interest in their application for biomarker discovery and therapeutic development. Engineered and patient-specific EVs derived from iPSCs are emerging as promising tools for targeted, cell type-specific, therapeutic approaches, although their clinical applicability still requires further validation. This review discusses the emerging evidence supporting the dual role of iPSC-derived glial EVs in health and disease, underscores the translational potential of iPSC-based platforms for mechanistic studies, and outlines their promise as precision medicine tools for diagnostics and therapy.\n\nID: 42347120\nTitle: RNA-Binding Proteins in Ageing and Age-Related Disease.\nAbstract: RNA-binding proteins (RBPs) are essential regulators of all aspects of RNA metabolism, including splicing, stability, localisation, translation, and degradation. Through their ability to recognise specific cis-elements in target transcripts, often via RNA-recognition motifs or other conserved domains, RBPs enable rapid cellular adaptation to stress and maintain proteostasis, particularly in post-mitotic tissues with limited transcriptional flexibility. Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing. Limitations of current models and priorities for future translational research are discussed.\n\nID: 42334507\nTitle: Associations influencing quality of life in caregivers of patients with amyotrophic lateral sclerosis: a stress-process model approach.\nAbstract: Caring for patients with amyotrophic lateral sclerosis (ALS) involves demands that reduce caregivers' quality of life. Although caregiver burden and perceived social support was conceptualized as an independent correlate of quality of life rather than a factor operating primarily through caregiver burden. This study examined these associations within a stress-process framework in which perceived social support was conceptualized as an independent correlate rather than a buffering factor. This cross-sectional analytical study included 118 informal caregivers of patients with ALS. Primary stressors were defined as patient functional status (ALSFRS-R), caregiving duration, and communication difficulty. Caregiver burden (Zarit Burden Interview) was considered a secondary stressor. Physical and mental quality of life were assessed using the SF-12, and perceived social support was measured with the Multidimensional Scale of Perceived Social Support. Hierarchical regression analyses were performed to examine associations specified in the conceptual model while controlling for caregiver sociodemographic and socioeconomic variables. Additional mediation analyses were conducted to examine whether caregiver burden mediated the relationship between perceived social support and quality of life. Poorer patient functional status was significantly associated with higher caregiver burden, whereas communication difficulty showed a positive but non-significant association after adjustment for caregiver characteristics. Caregiver burden showed negative associations with both physical and mental quality of life. Perceived social support remained positively associated with quality of life after adjustment for caregiver burden and contributed additional explained variance in the models. Mediation analyses showed no evidence that caregiver burden mediated the association between perceived social support and either physical or mental quality of life. The findings are consistent with a stress-process framework in ALS caregiving, in which caregiver burden represents a central factor statistically associated with both caregiving stressors and quality of life, while perceived social support shows an independent association with quality of life. These findings suggest that both caregiver burden and perceived psychosocial resources may be relevant to caregiver well-being, although causal and intervention-related implications require further investigation. Caring for a person with amyotrophic lateral sclerosis (ALS) is physically and emotionally demanding, and many caregivers experience reduced quality of life. Previous studies have examined caregiver burden and social support separately, but it is not well understood how these factors work together to influence caregivers’ well-being. This study examines how disease-related challenges, caregiver burden, and perceived social support are connected, and how these factors jointly affect the physical and mental quality of life of ALS caregivers. The study tests a conceptual model proposing that caregiving challenges increase caregiver burden, which in turn affects quality of life, while perceived social support contributes directly to quality of life rather than simply reducing stress. Worse patient functioning and communication difficulties were linked to higher caregiver burden. Higher burden was associated with poorer physical and mental quality of life. Perceived social support remained positively related to quality of life even after accounting for caregiver burden. These findings suggest that improving social support and reducing caregiver burden are both important for maintaining quality of life among ALS caregivers.\n\nID: 42313873\nTitle: COVID-19 alert level systems-Lessons learnt for future public health emergencies: A qualitative study.\nAbstract: During the COVID-19 pandemic, Alert Level Systems (ALS) were widely implemented as public health tools to communicate risk levels and recommend public health and social measures (PHSMs). However, the efficacy of ALS in mitigating disease spread and their impact on public health responses have not been systematically evaluated. This study aims to assess perceptions of ALS implementation across diverse jurisdictions and derive lessons for future public health emergencies. Key informant interviews were conducted remotely between December 2023 and March 2024 with senior stakeholders who were involved in ALS development and implementation during the COVID-19 pandemic, from eight jurisdictions: California (US), New Zealand, the Philippines, Rio Grande do Sul (Brazil), Singapore, South Africa, the United Kingdom, and the United States. A thematic analysis approach was applied to synthesize insights, focusing on the strengths, challenges, and key lessons from ALS implementation. ALS were generally perceived by key informants as useful tools for communicating risk and supporting adherence to PHSMs due to their simplicity and transparency. However, significant challenges were identified, including difficulties in accessing reliable data, lack of clear ALS objectives, and insufficient community engagement. The study highlights the need for ALS to integrate social, economic, and epidemiological data in decision-making processes. Jurisdictions also reported that pre-existing ALS governance structures and stronger community feedback mechanisms could have improved implementation outcomes. ALS can serve as valuable public health communication tools in future epidemics, but their success depends on clear objectives, evidence-based PHSMs, and robust community engagement. Pre-emptive development of ALS structures and governance will improve preparedness for future epidemics. Transparent and flexible decision-making processes will be crucial for sustaining public trust.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson’s complementary-but-disjoint (A-B-C) model.

An operator-independent AI-based automatic segmentation of the tongue was applied to 3-D MRI data of the head in SBMA in order to quantify the tongue atrophy. Thirty-nine patients with SBMA and 51 age-matched healthy controls underwent MRI which were used for tongue volume quantification. A single triplanar convolutional neural network of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head, the resulting volumes were processed slice-wise across the three orientations and corrected for age. At the group level, a significant atrophy of the tongue was observed in SBMA when compared to controls (p < 0.05). Atrophy correlated well with total SBMA-functional rating scale and even more with bulbar subscores. In summary, the study employed an AI-assisted advanced imaging analysis to quantify the tongue morphology in individuals with SBMA in correlation to clinical bulbar function, suggesting this approach as a potential biomarker for disease assessment.\n  --- END ACTUAL ABSTRACT FOR 42251620 ---\n\n- ERROR: You cited ID: 42204548 for the quote: \"Mediation analyses identified significant indirect associations between DTI-ALPS and both functional and cognitive measures through a pathway involving cortical FWF, white matter FWF, and fwcFA.\"\n  FACT: Strict Misquote Detected!

Impaired clearance of neurotoxic proteins has led to increasing interest in the brain glymphatic system; however, its in vivo associations with brain microstructure and clinical heterogeneity remain incompletely understood. One hundred forty-six patients with ALS and 149 demographically matched healthy controls (HCs) underwent multimodal MRI and comprehensive clinical assessments. Putative glymphatic function was quantified using diffusion tensor imaging along perivascular space (DTI-ALPS). Extracellular free water fraction (FWF) and free-water-corrected fractional anisotropy (fwcFA) were derived to characterize extracellular fluid and white matter microstructure. Group differences were assessed using vertex-wise and voxel-wise analyses with correction for multiple comparisons. Associations among imaging metrics and clinical measures were evaluated using correlation and serial mediation analyses. Compared with HCs, patients with ALS exhibited significantly reduced DTI-ALPS index, widespread increases in cortical FWF, bidirectional alterations in white matter FWF, and extensive reductions in fwcFA across major white matter tracts. Reduced DTI-ALPS was associated with changes in extracellular free water and white matter microstructural integrity, whereas FWF and fwcFA measures were associated with functional, cognitive, and emotional outcomes. Mediation analyses identified significant indirect associations between DTI-ALPS and both functional and cognitive measures through a pathway involving cortical FWF, white matter FWF, and fwcFA, although direct associations were not observed. These findings provide in vivo evidence that putative glymphatic dysfunction co-occurs with extracellular fluid alterations, white matter microstructural changes, and clinical impairment in ALS. Multi-compartment diffusion imaging may offer complementary markers for characterizing brain microstructure and its clinical relevance in ALS.\n  --- END ACTUAL ABSTRACT FOR 42204548 ---\n\n- ERROR: You cited ID: 42152867 for the quote: \"ALSSS speech scores was relatively preserved from 5.43 (95% CI 3.01-7.84) to 5.29 (95% CI 2.87-7.70) in the ASSET treatment group.\"\n  FACT: Strict Misquote Detected!

This study aims to evaluate the effectiveness of A Successful Swallowing with Effortful Training (ASSET) program, included in the 'The 365 Healthy Swallow Health Coach application' in preserving speech and swallowing abilities in ALS patients through self-training. In this 8-week quasi-experimental study, 13 participants were allocated to either the app-guided ASSET training group (n=7; three sessions per day, five days per week) or a usual-care control group (n=6) based on their clinical visit schedules. To evaluate changes over time and compare the two groups, linear mixed models were employed. Changes in ALS severity scale (ALSSS), Diadochokinetic (DDK) task, speech intensity, Speech Handicap Index-15, Dysphagia Handicap Index, Swallowing Quality of Life (SWAL-QOL), and Brief Inventory of Swallowing Assessment-15 were assessed. ALSSS speech scores was relatively preserved from 5.43 (95% CI 3.01-7.84) to 5.29 (95% CI 2.87-7.70) in the ASSET treatment group, but declined from 6.33 (95% CI 3.73-8.94) to 4.83 (95% CI 2.23-7.44) in the control group, with a significant group-by-time interaction (p=.017). DDK/tuh/and/kuh/were relatively preserved from 11.86 to 11.71 and from 12.29 to 11.57 respectively in ASSET group, but declined from 11.67 to 7.50 and from 11.83 to 7.17 in the control group, with significant interactions in/tuh/(p=.032) and/kuh/(p=.044). SWAL-QOL total score was relatively preserved from 155.86 to 149.71 in ASSET group, but declined from 154.67 to 125.17 in the control group, with a significant interaction (p=.011). The findings suggest that ASSET program may help preserve speech and swallowing function in patients with ALS.

Unpaid care partners often make high-stakes decisions with limited preparation, and residents are inconsistently included. To explore how serious illness communication occurs with residents living with dementia, unpaid care partners, and healthcare providers in LTC, and to identify practice-relevant communication strategies and contextual factors applicable to clinical practice. An integrative review following Toronto and Remington's six-stage methodology included 31 high-relevance studies (qualitative, quantitative, mixed methods, reviews, theoretical) published from 2015 to 2025 on serious illness, goals-of-care, or end-of-life communication in LTC dementia care. Directed content analysis was guided by Tarbi et al.'s basic science of communication in serious illness (lexical, non-lexical, contextual elements, and outcomes). Serious illness communication was predominantly biomedical and documentation-focused, often occurring at admission or during crises and directed mainly to unpaid care partners, with limited resident involvement. Lexical practices such as clear, jargon-free information, explicit invitations to discuss \"what matters most,\" and early conversations about hypothetical future scenarios enhanced trust, preparedness, and alignment of care with resident values. Non-lexical elements (tone, eye contact, pacing, use of silence) shaped perceived empathy but were seldom explicitly addressed by interventions. For LTC healthcare providers, embedding earlier, iterative serious illness communication, explicitly involving residents where possible, and cultivating both lexical and non-lexical skills are key to achieving relationship-centred, legally compliant, and goal-concordant palliative approaches to care.​. This review looked at how people talk about serious illness and end-of-life care with residents living with dementia in long-term care (LTC) homes, and how these conversations affect care decisions. Serious illness communication includes discussions about what matters most to residents as their dementia progresses, what kinds of treatments they would or would not want, and how unpaid care partners and healthcare providers can prepare for future changes and dying. The review found that these conversations in LTC usually happen late in the illness, often during admission to an LTC home or during a crisis and focus mainly on medical decisions or paperwork (for example, hospital transfer forms or resuscitation status). Residents with dementia are often not included directly and most conversations are held with unpaid care partners, who can feel unprepared or distressed. How healthcare providers communicate (by tone of voice, eye contact, body language, and use of silence) can strongly influence whether families feel heard, respected, and able to trust the team. The way LTC homes are organized also shapes these conversations. Staffing levels, continuity of staff, time pressures, leadership support, and charting systems all influence whether serious illness discussions are ongoing and person-centred, or brief, checklist-style tasks. When communication works well, unpaid care partners report better understanding of what to expect, more confidence in making decisions, and care that is better aligned with the resident’s values near the end-of-life.\n  --- END ACTUAL ABSTRACT FOR 42369228 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"Speech‑derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear.\" (Source: 42333954)\n- \"Reduced speaking and articulation rates were associated with thinning in both oral motor cortices.\" (Source: 42333954)\n- \"Measures of pausing behavior were negatively associated with frontal cortical regions.\" (Source: 42333954)\n- \"Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration.\" (Source: 42333954)\n- \"Furthermore, speech measures can show functional decline before the ALSFRS-R does, while also capturing differences between participants with bulbar symptoms and those without.\" (Source: 41981045)\n- \"AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates.\" (Source: 41511908)\n- \"ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS.\" (Source: 41511908)\n- \"Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis.\" (Source: 42298083)\n- \"We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them.\" (Source: 42310450)\n- \"The identified profiles were not significantly associated with clinical diagnostic categories.\" (Source: 42191539)\n- \"Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline.\" (Source: 41928799)\n- \"Wearable technology can positively contribute to elder care but a number of key issues and barriers remain.\" (Source: 42394053)\n- \"We found that at the early stage of protein aggregation, CTD of TDP-43 formed two morphologically different protein aggregates: donut-like (DO) and round (RO) oligomers.\" (Source: 42389895)\n- \"This perspective aims to support globally applicable strategies for improving chemo-immunotherapy effectiveness and access.\" (Source: 42360520)\n\n\nINSTRUCTION: Study the actual abstracts provided.

We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100 000 population, and age-standardised rates per 100 000 population. We estimated 1·17 billion (95% uncertainty interval 1·06-1·31) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14 210·7 cases (12 849·5-15 940·1) per 100 000 population. These estimates represented a 95·5% (75·0-121·2) increase in prevalent cases and 24·2% (11·4-41·4) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070·5 DALYs (1519·1-2750·5) per 100 000 population. Mental disorders contributed to 6·1% (4·8-7·6) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17·3% (14·8-20·6) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239·6 [1643·7-3014·1] per 100 000) than among males (1900·2 [1399·8-2510·8] per 100 000), and peaked in the 15-19 years age group (2617·3 [1850·6-3696·8] per 100 000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302·4 (952·7-1683·7) per 100 000 in Viet Nam to 3555·8 (2661·9-4715·0) per 100 000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853·0 (1352·1-2469·3) per 100 000 for middle SDI to 2184·1 (1606·1-2890·3) per 100 000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required.

Scientific evidence demonstrates that subclinical changes in speech and voice production—specifically variations in speaking and articulation rates—are detectable before significant decline in clinical functional communication outcomes, suggesting these digital biomarkers may function as early indicators of bulbar motor neuron degeneration.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe early identification of ALS remains a clinical challenge, particularly regarding the onset of bulbar impairment. Recent research indicates that objective digital biomarkers are capable of capturing motor speech degradation at stages where traditional assessments, such as the ALS Functional Rating Scale-Revised (ALSFRS-R) or routine neurological examinations, may remain insensitive. Structural-functional network decoupling, particularly within the somatomotor network, appears to underpin these early changes. The degradation of speech-related metrics, including alternating motion rates (AMR) and articulation velocity, serves as a refined surrogate for motor unit degeneration. As identified in recent literature, these changes correlate with cortical thinning in the oral motor cortex and may reflect underlying pathophysiological markers, such as glymphatic system dysfunction and neuroinflammation, long before overt, severe dysarthria presents.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Structural-functional decoupling in the somatomotor network is a primary signature of early-stage ALS.\n*   Speech-derived digital biomarkers track disease progression with higher sensitivity than the standard ALSFRS-R bulbar subscore.\n*   The choroid plexus exhibits progressive enlargement across disease stages, offering a potential neuroimaging marker for neuroinflammatory processes linked to disease evolution.\n*   Cortical thickness in the precentral gyrus serves as a quantifiable metric that influences the efficacy of implantable brain-computer interfaces (iBCIs).\n*   Alternating motion rate (AMR) is a highly discriminative clinical tool for distinguishing spinal-onset from bulbar-onset phenotypes.\n*   Biomechanical voice markers, including specific parameters of vocal stability, provide high-performance mortality risk prediction models.\n*   Human precentral gyrus maps reveal a mosaic of highly intermixed body-part representations, with two distinct speech-preferential zones.\n*   The C-terminal domain of TDP-43 forms distinct oligomeric species (donut-like and round) during early protein aggregation, potentially mediating early toxicity.\n*   Digital health literacy remains a significant challenge for healthcare students, impacting the future implementation of advanced diagnostic tools.\n*   Interoperability in radiological and emergency settings is a safety-critical requirement for the \"digital patient journey\" in neurodegenerative disease care.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

neurodegenerative disease affecting both upper and lower motor neurons, with bulbar dysfunction manifesting in up to 80% of patients. Dysarthria, characterized by impaired speech production, is common in ALS and often correlates with disease severity. Voice analysis has emerged as a promising tool for detecting disease progression and monitoring functional status. Methods: This study investigates acoustic and biomechanical voice alterations in ALS patients and their association with clinical measures of functional independence. A descriptive observational case series study was conducted, involving 43 ALS patients and 43 age and sex matched controls with non-neurological voice disorders. Sustained vowel /a/ recordings were obtained and analyzed using Voice Clinical Systems® and Praat software (version 6.2.22). Biomechanical and acoustic parameters were correlated with ALS Functional Rating Scale-Revised (ALSFRS-R) and Barthel Index scores. Results: Significant differences were observed between ALS and control groups (elevated muscle force and tension and interedge distance in non-ALS individuals). Between bulbar and spinal ALS subtypes, elevated values were observed in certain parameters in Bulbar ALS patients, indicating irregular vocal fold contact and weakened phonatory control, while spinal ALS exhibited increased values, suggesting higher phonatory muscle tension. Elevated biomechanical parameters were significantly correlated with low ALSFRS-R scores, suggesting a possible relationship between voice measures and functional decline. However, acoustic measurements showed no relationship with performance status. Conclusions: These results highlight the potential of voice analysis as a non-invasive, objective tool for monitoring ALS stage and differentiating between subtypes. Further research is needed to validate these findings and explore their clinical applications.","40450589":"ID: 40450589\nTitle: Differentiating upper- and lower motor neuron diseases using automated acoustic analysis.\nAbstract: Motor neuron diseases (MNDs) result in a spectrum of motor impairments, including considerable effects on speech function, which manifest as dysarthria-a motor speech disorder. Speech metrics are increasingly recognized as critical biomarkers with potential utility in disease diagnosis and phenotyping. This study aimed to (1) characterize acoustics of upper motor neuron (UMN) and lower motor neuron (LMN) dysarthria presentations in MNDs, and (2) identify relationships between bulbar disease severity scores and acoustic features, as these could collectively enable personalized approaches to management of these diseases. Data from 16 individuals with primary lateral sclerosis (PLS) representing UMN disease, 14 individuals with spinal and bulbar muscular atrophy (SBMA) representing LMN disease, and 25 neurologically healthy individuals were analyzed. Clinical measures were also collected from PLS and SBMA groups. All participants were remotely recorded performing passage reading, rapid syllable repetition, and vowel phonation. Fifty-two acoustic features were extracted representing articulation, phonation, prosody, resonance, and overall speech timing. Features were compared using Kruskal-Wallis tests for between-group comparisons and Spearman correlations between acoustic features and clinical scores. Articulatory and prosodic features best differentiated PLS, SBMA and controls. Correlations were observed in the PLS group between the clinical score and various articulatory features, most notably those indexing tongue and jaw movements. Our study demonstrated that acoustic assessment could capture fingerprints of dysarthrias associated with PLS and SBMA. These findings also demonstrate the potential for remote speech assessment to characterize diverse dysarthria profiles and pave the way for creating ways for personalized disease management approaches in clinical care and trials.","40460399":"ID: 40460399\nTitle: Construct Validity of the Amyotrophic Lateral Sclerosis Bulbar Dysfunction Index-Remote.\nAbstract: The Amyotrophic Lateral Sclerosis Bulbar Dysfunction Index-Remote (ALSBDI-R) is a clinician-administered tool designed to assess bulbar dysfunction remotely in patients with amyotrophic lateral sclerosis (ALS). This study aimed to evaluate the construct validity of the ALSBDI-R by examining its correlation with established clinical measures and its ability to discriminate among different bulbar disease severities. A total of 92 patients with ALS were recruited from two multidisciplinary clinics. Participants were assessed using the ALSBDI-R, the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R), the Center for Neurologic Study Bulbar Function Scale (CNS-BFS), the Sentence Intelligibility Test, and the Eating Assessment Tool (EAT-10). Construct validity was established through Spearman correlations and comparison of ALSBDI-R scores across bulbar severity groups (asymptomatic, mild, moderate, severe). Strong correlations were found between ALSBDI-R total scores and bulbar-specific measures such as ALSFRS-R bulbar subscore (r = -.85), CNS-BFS (r = .85), and EAT-10 (r = .77). The ALSBDI-R effectively discriminated between severity groups, supporting its construct validity. Severity bins were created based on median ALSBDI-R total scores for each group. The ALSBDI-R is a valid tool for remotely assessing bulbar dysfunction in patients with ALS. Despite several limitations, its ability to capture varying degrees of severity makes it valuable for clinical use and research, offering a standardized approach to monitor disease progression remotely.","40466410":"ID: 40466410\nTitle: [Use of tongue pressure to determine the indication for instrumental swallowing assessment in patients with spinal ALS].\nAbstract: Systematic swallowing assessment in amyotrophic lateral sclerosis (ALS) is essential, as approximately 85% of patients will develop dysphagia, and 8% of these cases may remain clinically silent. Although instrumental diagnostic tools exist, they are not always accessible. Recent studies suggest that lingual pressure measurements may be valuable for early detection of bulbar dysfunction. This study aims to establish lingual pressure cutoff points for early screening of such dysfunction. Transversal study based on prospectively collected data from patients with spinal-onset ALS at the Motor Neuron Unit, Hospital del Mar (Barcelona). A total of 58 patients were included. Anterior (PA) and posterior (PP) lingual pressures were measured using the IOPI system and analyzed alongside the ALSFRS-R scale. Statistical analysis included descriptive statistics, Spearman correlation, and ROC curve analysis (SPSS v25). A moderate correlation was found between lingual strength and ALSFRS-R scores (PA: r=.634, P<.001; PP: r=.539, P<.001). Identified cutoff values: PA: 39.5kPa (AUC=.766; 95%CI: .700-.831; P<.001), sensitivity 64.6%, specificity 76.4%. PP: 37.0kPa (AUC=.726; 95%CI: .653-.799; P<.001), sensitivity 55.1%, specificity 72.2%. In spinal-onset ALS, a moderate correlation exists between global functionality and lingual pressures. Cutoff points of PA=39.5kPa and PP=37.0kPa are proposed for early screening of bulbar dysfunction.","40506548":"ID: 40506548\nTitle: An instantaneous voice-synthesis neuroprosthesis.\nAbstract: Brain-computer interfaces (BCIs) have the potential to restore communication for people who have lost the ability to speak owing to a neurological disease or injury. BCIs have been used to translate the neural correlates of attempted speech into text1-3. However, text communication fails to capture the nuances of human speech, such as prosody and immediately hearing one's own voice. Here we demonstrate a brain-to-voice neuroprosthesis that instantaneously synthesizes voice with closed-loop audio feedback by decoding neural activity from 256 microelectrodes implanted into the ventral precentral gyrus of a man with amyotrophic lateral sclerosis and severe dysarthria. We overcame the challenge of lacking ground-truth speech for training the neural decoder and were able to accurately synthesize his voice. Along with phonemic content, we were also able to decode paralinguistic features from intracortical activity, enabling the participant to modulate his BCI-synthesized voice in real time to change intonation and sing short melodies. These results demonstrate the feasibility of enabling people with paralysis to speak intelligibly and expressively through a BCI.","40540830":"ID: 40540830\nTitle: Pick's disease presenting as progressive apraxia of speech: Atypical clinical and neuroimaging features in three autopsy-confirmed cases.\nAbstract: Patients with progressive apraxia of speech (PAOS) often develop atypical parkinsonian features suggestive of corticobasal syndrome (CBS) or progressive supranuclear palsy (PSP), and typically have an underlying 4-repeat tauopathy at autopsy. We describe three cases of PAOS with underlying Pick's disease, a 3-repeat tauopathy, who lacked CBS or PSP features during life. We reviewed patients enrolled in the Neurodegenerative Research Group's ongoing studies on speech and language disorders and identified those with PAOS who had autopsy-confirmed Pick's disease. All patients had comprehensive neurologic, speech-language, and neuropsychological assessments, as well as multimodal neuroimaging, during life. Three female patients presented with phonetic PAOS without parkinsonism. Patient 1 had speech onset at age 54, later developed behavioral variant frontotemporal dementia (bvFTD), and died at 64. Patient 2 had speech onset at 47, early bvFTD features, prominent frontal and temporal involvement, and died at 53. Patient 3 had speech onset at 58, minimal behavioral changes, primarily frontal involvement on imaging, and died at 63. Our findings highlight that Pick's disease can present with PAOS and may be distinguished from 4R-tau PAOS by an absence of motoric CBS/PSP features and, in some cases, by prominent temporal hypometabolism with bvFTD development. These atypical features may prove useful in the antemortem identification of Pick's disease as a cause of PAOS.","40571609":"ID: 40571609\nTitle: Can Language Characteristics Contribute to the Classification of Neurodegenerative Disorders? -An Exploratory Study.\nAbstract: Objective Evaluating language symptoms is challenging owing to their varied presentations. We developed a Japanese Language Screen (JLS) to assess 11 language aspects, including agrammatism, impairment of articulation and prosody (IAP), word recall, syntactic comprehension, meaning of proverbs, and writing, considering the unique features of the Japanese language. Methods Using the JLS, we assessed the language functions in patients with Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and healthy controls (HC) to identify language symptoms specific to each condition and determine whether the JLS can differentiate between diseases and HC. Results The study included 168 participants. The total JLS score categorized the participants' language status as normal or impaired. According to the total score, PSP patients had more severe language deficits than AD patients, despite comparable cognitive scores. Substantial differences were found in the 11 assessed items for each disease. Patients with AD and PSP showed decreased performance in more than half of the items compared to HC, with the PSP group being more impaired. ALS patients showed decreases in IAP and writing, notably in the meaning of proverbs, whereas PD was closely comparable to HC. Conclusion This study suggests that while the JLS is useful for understanding the language symptoms associated with neurodegenerative disorders, its ability to classify them remains limited.","40673749":"ID: 40673749\nTitle: An Explanatory Model of Speech Communication Centered on Multiscale Rhythmic Modulation: Implications for Motor Speech Assessment and Intervention for Individuals With Amyotrophic Lateral Sclerosis.\nAbstract: This study proposed an explanatory model of speech communication centered on multiscale rhythmic modulation to inform motor speech assessment and management. To these ends, a fit-for-purpose, automated measurement tool was used to evaluate and/or cross-validate (a) the previously reported effect of a neuromotor disorder-amyotrophic lateral sclerosis (ALS)-and (b) the effects of two cueing strategies, commonly used in managing motor speech disorders, on rhythmic modulation of speech. A secondary analysis was carried out on the X-ray Microbeam database. The analyzed data included the articulatory-kinematic and acoustic recordings of a phonetically loaded sentence produced by 19 individuals with ALS and 23 neurologically healthy controls in one habitual style and two nonhabitual styles as elicited by the slow and clear speech cues, respectively. The measurement tool quantified the modulation patterns of four articulators as well as four critical-band and one wide-band envelopes at three linguistically relevant timescales (delta, theta, beta/gamma) to assess rhythm control at the prosodic, syllabic, and subsyllabic levels. To address the research aims, the disease and speaking style effects on all modulation metrics were evaluated. For Aim 1, speakers with ALS showed reduced modulation depth of multiple articulators and critical-band envelopes at all timescales. For Aim 2, the slow speech cue elicited changes in articulatory modulation at multiple timescales, globally enhancing the control of all and especially syllabic and subsyllabic rhythms in speakers with ALS. Clear speech primarily elicited changes in articulatory modulation at the theta timescale, generating a more restricted effect on syllabic rhythm. The findings generally aligned with our prior research, supporting the robust utility of the measurement tool for assessing rhythmic disturbances of speakers with ALS. Moreover, this tool showed promise for delineating cueing-elicited changes in rhythmic modulation of speech, which has potential implications in tailoring and evaluating the outcomes of behavioral intervention.","40726766":"ID: 40726766\nTitle: Listener effort measures clinically meaningful change of dysarthria in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative motor neuron disease that can cause progressive bulbar dysfunction and dysarthria, resulting in reduced quality of life. Quantitative motor speech analysis can identify features of dysarthria that worsen with ALS progression but are not, inherently, clinically meaningful. Listener effort (LE) is a clinician-rated feature describing how much effort the listener needs to exert to understand the dysarthric speaker. This study investigated whether LE could act as a clinically meaningful measure of ALS dysarthria that could be used as an outcome measure in clinical trials. The Everything ALS Speech Study obtained longitudinal clinical information and speech recordings from 292 participants. In a subset of 125 participants, we measured speaking rate and three speech-language pathologists (SLPs) with expertise in ALS rated LE. We also built and tested a LE prediction algorithm to predict the SLPs' rating of LE. In addition, all speech recordings and associated clinical data are now being made available to ALS researchers via the Everything ALS portal. LE intra- and inter-rater reliability was very high (ICC 0.94-0.95). LE correlated with other measures of dysarthria at baseline and changed over time in participants with ALS (slope 0.77 pts/month, SE = 0.15, P < 0.001) but not controls (slope 0.005 pts/month, SE = 0.02, P = 0.807). The slope of LE progression was faster in people with bulbar onset than non-bulbar onset ALS (1.66 points/month versus 0.42 pts/month; P < 0.001) but was similar in all participants who had bulbar dysfunction at baseline, regardless of ALS site of onset (1.52 pts/month for bulbar onset versus 0.98 pts/month for non-bulbar onset with current bulbar involvement; P = 0.36). The LE prediction model predicted the true LE, with an average R 2 of 0.83 ± 0.07. Dysarthria is associated with decreased quality of life in people with ALS. Quantitative measures of dysarthria in ALS could be useful as ALS clinical trial outcome measures, providing insight into the progression of bulbar symptoms. Speaking rate quantifies progression but is variable across speaking stimuli, emotional states and contextual factors. LE is more inherently clinically meaningful, can be measured reliably by SLPs, changes quantitatively over time and is highly reproducible, thus may be useful as a clinical outcome assessment for ALS clinical trials. Furthermore, a LE prediction model is effective at predicting LE scores and should be validated on an external dataset.","40808712":"ID: 40808712\nTitle: Acoustic signatures of bulbar ALS: Predictive modeling with sustained vowels and LightGBM.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a degenerative neurologic disease with no definitive biomarkers for early detection. This paper discusses the use of acoustic analysis of sustained vowel phonations (SVP) and machine learning in ALS detection. An SVP corpus of 128 (64 /a/ and 64 /i/) from 31 patients with ALS and 33 healthy controls (HC) was employed. 131 acoustic features, including jitter, shimmer, Mel-Frequency Cepstral Coefficients (MFCCs), and Pathological Vibrato Index (PVI), were extracted. A LightGBM (Light Gradient Boosting Machine)-based model was built and optimized using 5-fold cross-validation to separate ALS cases. Model performance and feature importance were evaluated. The model performed well with high predictability, yielding an RMSLE of 0.162 and most predictions closely correlating with actual diagnoses. The top features obtained were S55_i, CCI(2), and dCCa(12), which were consistently at the top of the ranking list, indicating their role in ALS detection. The PVI was determined to be a significant biomarker with high values having high correlations with ALS diagnoses. But the multimodal nature of the predictive values indicated some flaws in generalization. This paper demonstrates the applicability of acoustic analysis and machine learning for early ALS detection. The proposed method provides an affordable, low-cost, and non-invasive way for ALS diagnosis with potential for application in telemedicine and clinical settings. Future research must expand datasets and integrate additional diagnostic modalities to improve the model's robustness and clinical translation.","40851280":"ID: 40851280\nTitle: Automatically measured speech intelligibility models bulbar-specific disease severity and progression in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that leads to widespread motor deterioration, including significant motor speech impairments. Speech intelligibility is a crucial component of communication affected in ALS, requiring objective, scalable assessment methods as an indicator of disease progression and treatment efficacy. Objective: This study investigates whether speech and bulbar function in ALS could be evaluated and monitored utilizing an automated digital measure of speech intelligibility derived from naturalistic picture descriptions. Methods: Speech recordings from 44 patients living with ALS (plwALS) and 49 matched healthy controls (HC) were analyzed and processed utilizing an automated speech analysis pipeline to extract an intelligibility score. These were part of a cross-sectional and longitudinal study involving two assessments. Results: The findings confirmed that speech intelligibility is significantly reduced in plwALS compared to HC. Those with bulbar-onset ALS have lower intelligibility than those with spinal-onset ALS, and the intelligibility of individuals with bulbar symptoms-regardless of the onset type-is lower than in plwALS without bulbar symptoms. Declining ALS-related speech scores correspond with worsening intelligibility in longitudinal assessments. Intelligibility correlates strongly with bulbar-specific clinical measures but not with global scores, highlighting its role in tracking bulbar progression. In some plwALS, we were able to demonstrate that automated speech analyses are more effective in detecting worsening in intelligibility earlier than standard clinical scoring. Conclusion: Our findings highlight that automated speech intelligibility assessments can be a valuable marker to improve clinical monitoring and facilitate earlier intervention in ALS as a supplement to standard assessments.","41004400":"ID: 41004400\nTitle: Atypical features including acquired oculomotor apraxia in C9orf72-associated familial primary lateral sclerosis.\nAbstract: The phenotypic variability of C9orf72-associated disease is broadening, including atypical and non-motor presentations. C9orf72-associated neurodegeneration has only rarely been associated with primary lateral sclerosis (PLS), and even more rarely with ocular motor apraxia. Describe a family with C9orf72 mutation presenting with frontotemporal dementia (FTD) and atypical PLS phenotypes and discuss the implications regarding 1) where PLS lies on the ALS-FTD spectrum, and 2) how C9orf72 mutations influence PLS clinically. Chart review. A 52-year-old male experiencing 4 months of progressive right lower leg spasticity with a family history of FTD was referred to us. Within 15 months, he was anarthric and required a powered wheelchair. He developed acquired ocular motor apraxia, consistent with supranuclear ophthalmoplegia. He later developed laryngeal dystonia which led to his death. Ten years later, his 67-year-old brother presented with 8 months of progressive spastic dysarthria, hyperreflexia, right foot drop, and right facial weakness. Genetic testing revealed heterozygous C9orf72 hexanucleotide repeat expansion. This family's presentation expands on sparse reports of C9orf72-associated PLS. The proband showcases a severity of ocular motor deficits not yet reported in PLS, extending ocular motor findings in MND. These deficits also provide clinical evidence of degeneration outside the motor cortex/spinal cord in PLS. The symptomatology (laryngeal dystonia, rapid progression) clinically overlaps with ALS/FTD, suggesting PLS may lie on the ALS-FTD spectrum. The severity and atypicality of this case also support suggestions that C9orf72 mutations amplify the spectrum/severity of disease observed in TDP-43 proteinopathies.","41004918":"ID: 41004918\nTitle: Tongue shear wave elastography for bulbar dysfunction in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) often manifests with tongue involvement, leading to dysarthria and dysphagia. While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ® E9, 9 MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80 kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48 kPa, range 8.50-21.42) and controls (14.16 kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p < 0.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS.","41082679":"ID: 41082679\nTitle: International Survey of Practice Patterns of Speech-Language Pathologists Working With Patients With Amyotrophic Lateral Sclerosis.\nAbstract: Speech-language pathologists (SLPs) evaluate and treat swallowing and communication impairments in individuals with amyotrophic lateral sclerosis (ALS). Standardized clinical practice guidelines for the evaluation and management of bulbar dysfunction in ALS have not yet been established. This study aimed to describe current international practice patterns of SLPs evaluating and treating bulbar dysfunction in ALS. Significant variability in practice patterns will exist across SLPs working in different clinical settings with varied resources. A 26-item Qualtrics survey was electronically distributed to SLPs via e-mail, social media, and professional discussion boards. Data from 245 respondents across 20 countries and 32 states within the United States were collected, with the final analysis including 214 respondents. Most respondents practiced in metropolitan areas (69%) and worked in multidisciplinary ALS clinics (41%), outpatient clinics (16%), and home health settings (17%). Cranial nerve examination (91%), swallow trials (79%), speech intelligibility tasks (85%), and diadochokinetic speech rates (65%) were frequently included in evaluations. Although 81% of clinics had access to instrumental swallowing evaluations, 32% reported performing them in fewer than 25% of patients. Communication evaluations were offered directly by 58% of clinicians, while 26% referred to an outside SLP and 16% collaborated with device representatives. Most clinicians provided patient education on swallowing (87%) and oral health (83%). However, managed practice varied widely, revealing no standardized treatment that is routinely offered. Barriers to optimal ALS care included time constraints, relevant clinical training, timing of treatment, addressing psychosocial components of care, access to resources, interdisciplinary communication, and insurance coverage (United States only). Findings reveal little consensus on symptomatic bulbar management and intervention timing. Results emphasize the urgent need for the development of a standardized minimal data set to best guide the evaluation and management of bulbar dysfunction in ALS. https://doi.org/10.23641/asha.30249997.","41095520":"ID: 41095520\nTitle: To Treat or Not to Treat: A Scoping Review of Speech Treatment for Dysarthria in Amyotrophic Lateral Sclerosis (ALS).\nAbstract: Speech loss is recognised as one of the most devastating outcomes for individuals with ALS, yet active speech intervention is rarely targeted in this population. Clinicians face significant challenges in managing dysarthria associated with ALS due to the rapidly progressive nature of the disease, historical concerns around intensive exercise accelerating decline, and an absence of direction on restorative and compensatory intervention strategies in current clinical care guidelines. This review evaluates the scope and quality of evidence for speech treatments in ALS to identify knowledge gaps and establish research priorities to guide clinical care. Studies were retrieved from six electronic databases (PubMed, CINAHL, Embase, Cochrane library, Web of Science, and PsycINFO). Four studies met inclusion criteria. Treatment approaches included: music-based speech therapy; multisubsystem speech rehabilitation program, tongue strengthening and articulation training; and Lee Silverman Voice Treatment-LOUD® combined with additional voice and articulation therapy. Sample sizes were small, with all studies demonstrating notable methodological weaknesses. The limited evidence base, marked by conflicting results and methodological flaws, prevents any reliable conclusions about treatment effectiveness. Despite the prevalence and impact of dysarthria in this population, evidence for speech treatment remains sparse, of generally low quality, and provides limited guidance for clinical practice. The changing perspective on exercise in ALS warrants rigorous investigation of tailored dysarthria interventions for this population that are minimally fatiguing and enhance speech by making use of residual physiologic support.","41149102":"ID: 41149102\nTitle: Oral Health Status in Patients with Amyotrophic Lateral Sclerosis: A Scoping Review.\nAbstract: Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative syndrome which often leads to progressive muscular dysfunction and therefore oral health deterioration. The aim of this scoping review is to evaluate oral health status in ALS patients focusing on the importance of dental care in improving patient's quality of life. Methods: A comprehensive literature search was conducted on PubMed, Scopus, Web of Science, and Embase databases until June 2025 using a combination of keywords and MeSH terms related to ALS and oral health. Studies were screened and selected based on inclusion and exclusion criteria, focusing on human clinical data reporting oral health outcomes in ALS. Results: Eight studies met the inclusion criteria. The findings showed a high prevalence of oral complications in bulbar-onset ALS patients. Common issues included reduced tongue mobility, poor oral hygiene, sialorrhea, and decreased masticatory function were evaluated. Conclusions: Oral health impairment in ALS patients frequently contributes to systemic risks and reduced quality of life. A dental expert may play an important role in multidisciplinary care teams in terms of early diagnosis and conservative treatment of oral diseases ranging from periodontal disease to temporomandibular disorders (TMD). Personalized oral hygiene strategies and adjunctive therapies may serve as key elements in maintaining overall health and patient comfort in ALS. Therefore, the objective of the following review was to evaluate oral health complication in patients with ALS, highlighting the impact of oral care on patients' quality of life.","41164053":"ID: 41164053\nTitle: Clinical Reasoning and Diagnostic Challenge in a 23-Year-Old Man With Rapidly Progressive Dysphagia and Hypophonia: Juvenile-Onset Amyotrophic Lateral Sclerosis Caused by a FUS Gene Mutation.\nAbstract: Dysphagia and dysphonia of unclear etiology in young adults pose a significant diagnostic challenge, as these symptoms are more commonly attributed to benign or structural causes rather than serious neurodegenerative disease. The absence of classic neuromuscular signs such as limb weakness, hyperreflexia, or fasciculations can delay consideration of motor neuron disease, particularly when bulbar symptoms occur in isolation. We describe a previously healthy 23-year-old man who presented with rapidly progressive dysphagia and hypophonia, initially misattributed to infectious causes. Despite an extensive workup for structural, autoimmune, and infectious causes, no clear etiology was identified. Neurologic examination revealed predominantly bulbar dysfunction, and electrodiagnostic studies showed acute to subacute denervation changes in the tongue and trapezius muscles. Genetic testing confirmed juvenile-onset amyotrophic lateral sclerosis due to a pathogenic FUS gene mutation (p.Pro525Leu). This case highlights the importance of including motor neuron disease in the differential diagnosis of rapidly progressive bulbar symptoms of unknown origin. It highlights the importance of early electrodiagnostic testing and genetic evaluation in establishing a diagnosis.","41199620":"ID: 41199620\nTitle: Acoustic Features in ALS: Taking a Pause to Appreciate a Novel Remote Respiratory Monitoring Strategy.\nAbstract: ","41205733":"ID: 41205733\nTitle: Repurposing immunomodulatory drugs targeting microglia for amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder that progressively affects upper and lower motor neurons, leading to symptoms including dysarthria, muscle weakness, and paralysis. The disease is multifactorial, with a variety of contributing pathways, including excitotoxicity, oxidative stress, and neuroinflammation. Current treatments target only two of these pathways with limited efficacy, highlighting the need for alternative approaches. Increasing evidence highlights the involvement of immune dysregulation, particularly microglial-mediated neuroinflammation, in ALS pathology. Fortunately, many immunomodulatory drugs acting on microglia are already available for other diseases, indicating promising opportunities for drug repurposing. This literature review provides an overview of existing drugs under investigation for ALS, including those that have failed, and highlights microglia-targeting compounds with emerging repurposing potential. Compounds such as ibudilast, fingolimod, and modafinil have shown encouraging initial clinical results, whereas others were well-tolerated but underpowered or failed to demonstrate efficacy. New candidates, such as azithromycin, montelukast, doxycycline, tofacitinib, quercetin, belinostat, propranolol, and several kinase inhibitors, have demonstrated positive preclinical results, supporting their advancement toward clinical evaluation. Overall, these findings emphasize the potential of microglia-targeting therapies for ALS. To realize this potential, future studies must include larger cohorts, assess effects across different disease stages and patient subgroups, and examine sex differences. This is essential to address patient heterogeneity and improve personalized treatments for ALS patients.","41255457":"ID: 41255457\nTitle: Early Multidisciplinary Rehabilitation Improves Swallowing and Speech Function in a Patient With Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a chronic, progressive neurodegenerative disease for which there is a lack of effective treatment.

In neurodegenerative diseases affecting the brainstem-such as progressive supranuclear palsy (PSP), amyotrophic lateral sclerosis (ALS), and multiple system atrophy (MSA)-bulbar dysfunction often impairs tongue propulsion and motility, affecting both swallowing (dysphagia) and phonation (dysarthria). This study aimed to investigate whether vowel-based acoustic features are associated with swallowing severity in brainstem-related disorders and to explore their potential as surrogate markers of bulbar involvement. Methods: This was a cross-sectional observational study. Thirty-one patients (13 PSP, 12 ALS, 6 MSA) underwent clinical dysarthria assessment, acoustic analysis of the first (F1) and second (F2) formants during sustained phonation of /a/, /i/, /e/, and /u/, and swallowing evaluation using standardized clinical scales (DOSS, FOIS, ASHA-NOMS) and fiberoptic endoscopic evaluation (Pooling Score, Penetration-Aspiration Scale). The vowel space area (tVSA, qVSA) and Formant Centralization Ratio (FCR) were computed. Results: Significant correlations emerged between acoustic vowel metrics and dysphagia severity, especially for liquids. The FCR showed strong correlations with DOSS (ρ = -0.660, p < 0.0001), FOIS (ρ = -0.531, p = 0.002), ASHA-NOMS (ρ = -0.604, p < 0.0001), and instrumental scores for liquids: the Pooling Score (ρ = 0.538, p = 0.002) and PAS (ρ = 0.630, p < 0.0001). VSA measures were also associated significantly with liquid swallowing impairment. F2u correlated with dysarthria severity and all liquid-related dysphagia scores. Conclusions: Vowel-based acoustic parameters, particularly FCR and F2u, reflect the shared neuromotor substrate of articulation and swallowing. Acoustic analysis may support early detection and monitoring of bulbar dysfunction, especially where instrumental assessments are limited.","41341425":"ID: 41341425\nTitle: Exploring Speech Biosignatures for Traumatic Brain Injury and Neurodegeneration: Pilot Machine Learning Study.\nAbstract: Speech features are increasingly linked to neurodegenerative and mental health conditions, offering the potential for early detection and differentiation between disorders. As interest in speech analysis grows, distinguishing between conditions becomes critical for reliable diagnosis and assessment. This pilot study explores speech biosignatures in two distinct neurodegenerative conditions: (1) mild traumatic brain injuries (eg, concussions) and (2) Parkinson disease (PD) as the neurodegenerative condition. The study included speech samples from 235 participants (97 concussed and 94 age-matched healthy controls, 29 PD and 15 healthy controls) for the PaTaKa test and 239 participants (91 concussed and 104 healthy controls, 29 PD and 15 healthy controls) for the Sustained Vowel (/ah/) test. Age-matched healthy controls were used. Young age-matched controls were used for concussion and respective age-matched controls for neurodegenerative participants (15 healthy samples for both tests). Data augmentation with noise was applied to balance small datasets for neurodegenerative and healthy controls. Machine learning models (support vector machine, decision tree, random forest, and Extreme Gradient Boosting) were employed using 37 temporal and spectral speech features. A 5-fold stratified cross-validation was used to evaluate classification performance. For the PaTaKa test, classifiers performed well, achieving F 1-scores above 0.9 for concussed versus healthy and concussed versus neurodegenerative classifications across all models. Initial tests using the original dataset for neurodegenerative versus healthy classification yielded very poor results, with F 1-scores below 0.2 and accuracy under 30% (eg, below 12 out of 44 correctly classified samples) across all models. This underscored the need for data augmentation, which significantly improved performance to 60%-70% (eg, 26-31 out of 44 samples) accuracy. In contrast, the Sustained Vowel test showed mixed results; F 1-scores remained high (more than 0.85 across all models) for concussed versus neurodegenerative classifications but were significantly lower for concussed versus healthy (0.59-0.62) and neurodegenerative versus healthy (0.33-0.77), depending on the model. This study highlights the potential of speech features as biomarkers for neurodegenerative conditions. The PaTaKa test exhibited strong discriminative ability, especially for concussed versus neurodegenerative and concussed versus healthy tasks, whereas challenges remain for neurodegenerative versus healthy classification. These findings emphasize the need for further exploration of speech-based tools for differential diagnosis and early identification in neurodegenerative health.","41343582":"ID: 41343582\nTitle: Comprehensive analysis platform to understand, remedy, and eliminate amyotrophic lateral sclerosis (CAPTURE ALS): Study protocol for a Canadian multicenter, multimodal, longitudinal observational study.\nAbstract: The marked heterogeneity of Amyotrophic Lateral Sclerosis (ALS) combined with a lack of biomarkers are key contributing factors to the lack of disease-modifying treatments. The Comprehensive Analysis Platform to Understand Remedy and Eliminate ALS (CAPTURE ALS) is a Canadian platform designed to create the most comprehensive picture of people living with ALS with the objective of facilitating ALS research initiatives worldwide. The main aims of CAPTURE ALS include: (1) to characterize ALS and healthy controls with biosamples and data in order to provide the most comprehensive picture of individuals living with ALS to date; (2) to create a de-identified database and biosample repository linked to detailed clinical information; and (3) to develop and implement an inclusive and transparent participant engagement strategy to be active throughout all stages of CAPTURE ALS. CAPTURE ALS is a prospective, multicenter, observational, longitudinal study. People living with ALS, or a related disease and healthy controls undergo a harmonized protocol including the collection of detailed clinical information, neurological and cognitive examination, speech recording, advanced magnetic resonance imaging, and biosampling. Data and samples are stored in a biobank operating under an open science governance framework. An inclusive and transparent participant engagement strategy was designed and implemented throughout all stages of CAPTURE ALS. Four sites are operating in the consortium with a fifth being onboarded. The target enrollment is 120 affected participants and 50 controls, with the first participant visit having occurred in March 2022. Recruitment is ongoing. CAPTURE ALS is a scalable clinical research platform that connects scientists and patients to facilitate efficient translational research. The unique and deeply phenotyped data and biosamples are a global resource towards the development of biomarkers and understanding ALS biology.

This degeneration leads to a gradual muscle weakness, dysarthria, dysphagia, respiratory insufficiency, and, in some patients, alterations in cognitive and behavioral performance. Regardless of advancements made in pharmacological and gene-targeted interventions, a definitive curative treatment remains elusive. Consequently, rehabilitation plays a pivotal role in preserving autonomy, participation, and overall quality of life. This review outlines the current evidence and clinical approaches related to multidisciplinary rehabilitation in ALS. It covers physical and occupational therapy, respiratory, speech and language, psychological, and palliative care domains. Evidence supports moderate tailored exercise programs, early respiratory therapy, and structured management of mobility deficits, spasticity, pain, dysphagia, and communication impairments as key elements of symptomatic treatment. Psychological and social support, which includes the involvement of caregivers and relatives, enhances emotional well-being and coping resilience. Even with progressive development of gene-targeted and disease-modifying therapies, rehabilitation will stay relevant for maintaining long-term motor function. This review highlights the need for standardized, evidence-based rehabilitation protocols and intensified neurorehabilitation research to strengthen clinical outcomes and quality of life as key therapeutic goals in ALS management.","41396714":"ID: 41396714\nTitle: What can vowel acoustics reveal about the communicative participation of people living with ALS?\nAbstract: Objective: Bulbar dysfunction often diminishes the accuracy and speed of the tongue, lip, and jaw movements necessary for speech production. Vowel acoustic features derived from speech recordings can serve as sensitive markers of articulatory accuracy and movement timing. We examined whether degraded speech caused by amyotrophic lateral sclerosis (ALS), assessed through vowel acoustic features, was associated with communicative participation restrictions. As a secondary aim, we assessed the association of two global speech characteristics, rate and intelligibility, with vowel features and communicative participation. Materials & Methods: Thirty-three people with ALS (plwALS) recorded a reading passage and completed surveys using a smartphone application. Speaking rate and acoustic vowel features (duration, vowel articulation index [VAI]) were extracted from the recordings. Three speech-language pathologists rated speech intelligibility. Communicative participation was assessed using the Communicative Participation Item Bank (CPIB) short form. Bivariate correlation, partial correlation, and regression analyses were used to evaluate the associations between vowel features, intelligibility, speaking rate, and CPIB scores. Results: Significant bivariate correlations, ranging from rs = -0.39 to rs = 0.64, were found between speech variables and CPIB scores. A combined regression model including VAI, vowel duration, and sex explained 52% of the variance in CPIB scores. Including speaking rate or intelligibility in the partial correlation analysis attenuated the associations between vowel acoustics and CPIB. Conclusions: Vowel features and global dysarthria characteristics are linked to communicative participation in ALS. Clinical practices designed to target vowel production, speaking rate, and intelligibility may help to maintain daily communication in ALS.","41467443":"ID: 41467443\nTitle: Mitochondria-associated endoplasmic reticulum membranes and calcium ion exchange: A novel direction for aging and neurodegenerative diseases.\nAbstract: Mitochondria-associated endoplasmic reticulum membranes serve as crucial signaling hubs mediating communication between the endoplasmic reticulum and mitochondria, and play a central role in calcium ion exchange. This dynamic interface regulates key cellular processes including bioenergetic metabolism, apoptosis, autophagy, and stress responses. Dysregulation of calcium transport associated with mitochondria-associated endoplasmic reticulum membranes can disrupt intracellular homeostasis, leading to mitochondrial dysfunction, oxidative stress, and neuronal death, which are hallmarks of aging and neurodegenerative diseases. This review systematically examines the functions of protein complexes within mitochondria-associated endoplasmic reticulum membranes and the pathogenic mechanisms of calcium signaling regulated by these membranes in neurodegenerative disorders. It places particular emphasis on structural alterations in calcium ion transport machinery as a common mechanism underlying various neurodegenerative diseases. In Alzheimer's disease, mitochondria-associated endoplasmic reticulum membranes exhibit a hyperactive state, promoting the generation of amyloid-β and enhancing calcium ion flux from the endoplasmic reticulum to the mitochondria. In contrast, in Parkinson's disease and amyotrophic lateral sclerosis, the activity of mitochondria-associated endoplasmic reticulum membranes is reduced, leading to a decline in mitochondrial calcium ion buffering capacity and exacerbating excitotoxicity. Proteins residing in mitochondria-associated endoplasmic reticulum membranes are disrupted across various neurodegenerative diseases, resulting in abnormal communication between the endoplasmic reticulum and mitochondria. Recent studies indicate that mitochondria-associated endoplasmic reticulum membranes play a bidirectional role in disease progression, and compensatory mechanisms often exacerbate the pathological process. Therapeutic strategies aimed at preserving the integrity of mitochondria-associated endoplasmic reticulum membranes hold promise for alleviating neurodegenerative damage. Therefore, calcium ion exchange mediated by mitochondria-associated endoplasmic reticulum membranes plays a key role in aging and neurodegenerative diseases, making it a highly promising therapeutic target.","41488323":"ID: 41488323\nTitle: Sigma receptors and mitochondria-associated ER membranes are converging therapeutic targets for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) begins decades before clinical symptoms emerge. The \"amyloid hypothesis\" suggests that amyloid-β (Aβ) deposition initiates a cascade of tau hyperphosphorylation, neuroinflammation, and neuronal loss leading to cognitive decline. The recent success of anti-Aβ therapies such as Leqembi in prodromal or mild cognitive impaired patients underscores the importance of early intervention and Aβ clearance. However, safety and cost limitations highlight the need for alternative therapeutic strategies. Small-molecule modulators of Sigma-1 and Sigma-2 receptors (σ1R and σ2R) have emerged as promising candidates for AD treatment. σ1R agonists exhibit neuroprotective and anti-amnestic effects under pathological conditions without affecting normal cognition. Beyond AD, σ1R is implicated in several neurodegenerative diseases including ALS (amyotrophic lateral sclerosis), Parkinson's, and Huntington's diseases, stroke, and epilepsy. σ1R plays a key role at mitochondria-associated ER membranes (MAMs)-specialized lipid raft-like domains that form functional membrane contact sites between the endoplasmic reticulum (ER) and mitochondria. β-secretase (BACE1), γ-secretase, and their substrates APP and palmitoylated APP (palAPP) localize in the MAMs, promoting amyloidogenic Aβ production. MAMs serve as dynamic hubs for inter-organelle communication, calcium signaling, and lipid metabolism. The \"MAM hypothesis\" proposes that MAM dysregulation drives early AD pathology and persists throughout disease progression, contributing to neurofibrillary tangle formation, calcium imbalance, and neuroinflammation. This review aims to summarize the current understanding of σ1R-mediated regulation of MAMs and its neuroprotective mechanisms, highlighting potential therapeutic opportunities for targeting σ1R in AD and other neurodegenerative disorders.","41496108":"ID: 41496108\nTitle: Recurarization after sugammadex reversal in a patient with amyotrophic lateral sclerosis: Case report.\nAbstract: Amyotrophic lateral sclerosis (ALS) confers heightened and unpredictable sensitivity to nondepolarizing neuromuscular blocking agents and a high risk of postoperative respiratory failure. Although sugammadex reliably reverses rocuronium, recurarization may occur and is likely under-recognized in ALS. We report 2 ALS patients undergoing percutaneous endoscopic gastrostomy, one of whom developed delayed recurarization after apparent reversal. Both women (67 and 68 years) presented with progressive dysphagia requiring percutaneous endoscopic gastrostomy. Case 1 had dyspnea, dysarthria, and long-standing noninvasive positive-pressure ventilation; Case 2 had bulbar signs without preoperative ventilatory support. The key perioperative concern in both cases was ventilatory failure from residual neuromuscular block. ALS had been established clinically. In Case 2, recurarization was diagnosed shortly after extubation when acute hypercapnic respiratory failure and clinical weakness followed an earlier recovery to a train-of-four (TOF) ratio of 92%. Intravenous anesthesia with propofol and remifentanil was used. Case 1 received rocuronium 10 mg (0.2 mg/kg) and was reversed with sugammadex 90 mg (2 mg/kg) at TOF count 0, achieving a TOF ratio of 98% within 3 minutes before extubation and postoperative noninvasive ventilation. Case 2 received rocuronium 30 mg (0.6 mg/kg) and sugammadex 200 mg (3.8 mg/kg) at TOF count 1, recovered to a TOF ratio of 92% at 4 minutes, but developed respiratory failure 3 minutes after extubation; mask ventilation and neostigmine 2 mg with atropine 0.25 mg were given. Case 1 recovered uneventfully and was discharged on postoperative day (POD) 6. Case 2 required intensive care unit admission, re-intubation on POD 1, and re-extubation on POD 3; she was discharged on POD 23 without new neurologic deficits. In ALS, recurarization can occur despite seemingly adequate sugammadex reversal. When rocuronium is used, sugammadex is recommended for reversal, with vigilant quantitative neuromuscular monitoring and extended post-extubation observation to detect delayed weakness.","41500873":"ID: 41500873\nTitle: Voice-Based Prediction of Survival in Amyotrophic Lateral Sclerosis (ALS) Patients Using Biomechanical Acoustic Markers.\nAbstract: To evaluate whether voice-derived acoustic and biomechanical features can serve as non-invasive biomarkers for mortality-risk prediction and survival stratification in patients with amyotrophic lateral sclerosis (ALS). We conducted a retrospective study including 50 ALS patients evaluated in a phoniatrics consultation with available sustained vowel recordings, demographic data, and functional assessments. Nested logistic regression models were developed to predict clinical outcomes, progressively incorporating demographic variables, functional indices (Grade, Roughness, Breathiness, Asthenia, Strain, and Barthel), acoustic features (fundamental frequency, jitter, shimmer, harmonics-to-noise ratio), and biomechanical voice parameters (Pr1-Pr22). Model performance was assessed using receiver operating characteristic curves and area under the curve (AUC) comparisons via DeLong tests. Stepwise Akaike Information Criterion (StepAIC) was applied to optimize the final model. A Cox proportional hazards model was used to evaluate the association between voice parameters and survival time. The final StepAIC model, which included a subset of biomechanical features, achieved excellent predictive performance (AUC = 0.903, 95% confidence interval: 0.816-0.989), significantly outperforming baseline and acoustic-only models. Bootstrapping confirmed the model's robustness and generalizability. Cox regression analysis showed that the derived risk scores stratified patients into tertiles with significantly different survival probabilities (log-rank P < 0.0001; hazard ratio for high vs. low-risk group = 11.2). Biomechanical voice features are strong predictors of mortality in ALS and outperform traditional clinical and acoustic indices. These findings support the integration of voice analysis into ALS monitoring protocols as a non-invasive, cost-effective, and scalable prognostic tool.","41504787":"ID: 41504787\nTitle: \"Bright Tongue\" and \"Wine Glass\" signs in amyotrophic lateral sclerosis.\nAbstract: A 43-year-old male patient presented with monoparesis in his left leg, which had persisted for one year, then progressed to spastic dysarthria, tetraparesis, wide-based gait, muscle atrophy, weakness, fasciculations, and signs of pyramidal signs in all limbs. Brain MRI findings revealed hyperintensities on T2/FLAIR and diffusion-weighted imaging (DWI) along the corticospinal tracts, extending from the corona radiata and internal capsules to the brainstem, the \"bright tongue sign\" and the \"wine glass sign,\". This case highlights the classic findings in amyotrophic lateral sclerosis, which was confirmed by electroneuromyography.","41511908":"ID: 41511908\nTitle: Utility of Simple Speech Measures in Amyotrophic Lateral Sclerosis Assessment: Focus on Alternating Motion Rate as a Screening Tool.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive degeneration of motor neurons. Early detection of bulbar symptoms is crucial for timely diagnosis and intervention; however, variability in symptom progression complicates clinical assessment. This retrospective observational study aimed to classify patients with ALS into three groups - spinal onset, spinal onset with bulbar involvement, and bulbar onset - and to identify speech evaluation metrics that effectively differentiate these groups. Data from 68 patients with ALS were retrospectively analyzed. Speech samples were collected and evaluated for alternating motion rate (AMR), maximum phonation time (MPT), nasality, maximum tongue pressure (MTP), speech rate, and speech intelligibility. Group comparisons and receiver operating characteristic (ROC) curve analyses were conducted to assess discriminatory ability. AMR significantly differed among the three groups, with the spinal-onset group demonstrating the highest rates and the bulbar-onset group showing the lowest rates. ROC analysis indicated that AMR exhibited excellent discriminatory power, particularly in distinguishing spinal-from bulbar-onset ALS. Significant differences were also observed in MTP, nasality, speech rate, and speech intelligibility, although some metrics were less effective in differentiating the intermediate group. No significant group differences were found in MPT. These findings suggest that the AMR is a sensitive and easily administered measure for detecting bulbar symptoms and distinguishing ALS subtypes. The intermediate characteristics observed in the spinal-onset with bulbar involvement group support this classification as a distinct clinical phenotype. Combining AMR with secondary measures such as MTP, nasality, speech rate, and speech intelligibility may enhance early detection of bulbar symptoms and improve clinical decision-making.","41562880":"ID: 41562880\nTitle: Dysphagia and Dysarthria in Neurodegenerative Diseases: A Multisystem Network Approach to Assessment and Management.\nAbstract: Dysphagia and dysarthria are common, co-occurring manifestations in neurodegenerative diseases, resulting from damage to distributed neural networks involving cortical, subcortical, cerebellar, and brainstem regions. These disorders profoundly affect patient health and quality of life through complex sensorimotor impairments. Objective: The aims was to provide a comprehensive, evidence-based review of the neuroanatomical substrates, pathophysiology, diagnostic approaches, and management strategies for dysphagia and dysarthria in neurodegenerative diseases with emphasis on their multisystem nature and integrated treatment approaches. Methods: A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases (2000-2024), focusing on Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). Search terms included \"dysphagia\", \"dysarthria\", \"neurodegenerative diseases\", \"neural networks\", \"swallowing control\" and \"speech production.\" Studies on neuroanatomy, pathophysiology, diagnostic tools, and therapeutic interventions were included. Results: Contemporary neuroscience demonstrates that swallowing and speech control involve extensive neural networks beyond the brainstem, including bilateral sensorimotor cortex, insula, cingulate gyrus, basal ganglia, and cerebellum. Disease-specific patterns reflect multisystem involvement: PD affects basal ganglia and multiple brainstem nuclei; ALS involves cortical and brainstem motor neurons; MSA causes widespread autonomic and motor degeneration; PSP produces tau-related damage across multiple brain regions. Diagnostic approaches combining fiberoptic endoscopic evaluation, videofluoroscopy, acoustic analysis, and neuroimaging enable precise characterization. Management requires multidisciplinary Integrated teams implementing coordinated speech-swallowing therapy, pharmacological interventions, and assistive technologies. Conclusions: Dysphagia and dysarthria in neurodegenerative diseases result from multifocal brain damage affecting distributed neural networks. Understanding this multisystem pathophysiology enables more effective integrated assessment and treatment approaches, enhancing patient outcomes and quality of life.","41663537":"ID: 41663537\nTitle: [Relatives in the context of assisted dying: challenges and support needs].\nAbstract: The decision to pursue physician-assisted dying can place a significant emotional burden on relatives. Despite the considerable psychosocial stress they often face, these individuals have received limited attention in research, clinical practice and ethical or societal debates surrounding this topic. This article provides an overview of the role of relatives in the context of physician-assisted dying.Previous studies indicate that relatives are frequently confronted with moral dilemmas, ambivalent emotions and anticipatory grief. In addition, they often take on organisational responsibilities in support of the person wishing to die and may experience stigma and subsequent social isolation. Research also suggests that relatives and close friends are at increased risk for mental health challenges.At the same time, certain aspects of the process, such as the opportunity to say goodbye, open communication and the active involvement of relatives, can have a positive effect and support a more adaptive grieving process. These findings highlight the importance of psychosocial support for relatives as well as the necessity of involving them at an early stage throughout the entire process. Die Entscheidung für einen assistierten Suizid kann für Angehörige mit erheblichen emotionalen Belastungen einhergehen. Trotz der vielfältigen psychosozialen Herausforderungen finden Angehörige in Forschung, Versorgung sowie in ethischen und gesellschaftlichen Diskursen zu diesem Thema bislang nur unzureichende Beachtung. Der vorliegende Artikel bietet einen Überblick über die Rolle der Angehörigen im Kontext des assistierten Suizids.Bisherige Studien zeigen, dass Angehörige häufig mit moralischen Dilemmata, ambivalenten Emotionen sowie antizipatorischer Trauer konfrontiert sind. Darüber hinaus übernehmen sie oftmals organisatorische Aufgaben zur Unterstützung der sterbewilligen Person und erleben nicht selten Stigmatisierung sowie daraus resultierende soziale Isolation. Zudem deuten bisherige Studienergebnisse darauf hin, dass Angehörige ein erhöhtes Risiko für die Entwicklung psychischer Erkrankungen aufweisen können.Gleichzeitig können bestimmte Merkmale des assistierten Suizids entlastend auf Angehörige wirken und die Verarbeitung des Verlusts positiv beeinflussen. Hierzu zählen unter anderem die Möglichkeit zur Abschiednahme, offene Kommunikation sowie die Einbindung in den Prozess des assistierten Suizids. Diese Befunde unterstreichen die Notwendigkeit spezifischer psychosozialer Unterstützungsangebote für Angehörige sowie deren frühzeitige Einbindung in relevante Prozesse.","41685589":"ID: 41685589\nTitle: Cognitive Dysfunction Is Associated With an Underestimation of Respiratory Function in ALS.\nAbstract: The association between low forced vital capacity (FVC) and cognitive impairment in ALS is ambiguous; it could be due to respiratory dysfunction and/or poor effort from cognitive deficits. We used the objective, non-volitional phrenic nerve motor response amplitude (PAmp) to clarify how cognitive status affects the relationship between diaphragmatic strength and FVC. This retrospective study included 73 patients with ALS followed in our clinic. FVC and PAmp were measured, and cognitive status was assessed with the Edinburgh Cognitive and Behavioral ALS Screen (ECAS). Regression models tested for associations between FVC and distinct ECAS domains and whether these domains influenced the PAmp-FVC relationship. PAmp (β = 0.58, p = 0.001) and its interaction with an abnormal ECAS's Executive score (β = -0.20, p < 0.045) were significant predictors of FVC. The latter indicated that patients with abnormal executive function had lower FVC than cognitively normal patients at similar PAmp values. Moreover, in patients with abnormal executive function, a reduction in PAmp was associated with a shallower decline in FVC. Severe bulbar dysfunction was also negatively associated with FVC (β = -0.22, p = 0.024). FVC may underestimate respiratory capacity in cognitively impaired patients; therefore, we recommend non-volitional measures when evaluating ALS patients with executive dysfunction.","41718496":"ID: 41718496\nTitle: Timing of communication and technology control support in ALS - a systematic review.\nAbstract: Objective: To review evidence on the optimal timing of interventions that support communication and technology control for people living with Amyotrophic Lateral sclerosis (ALS). Methods: A systematic review was conducted following a pre-registered protocol. Databases were searched for studies involving people living with ALS that addressed timing of assistive technology interventions for communication or technology control. Screening and data extraction were completed in duplicate, findings were synthesized using a thematic analysis, and relevant findings presented as a descriptive summary. Results: Twenty-eight studies met the inclusion criteria. Evidence focused overwhelmingly on communication support rather than wider assistive technology interventions. Need for a communication aid typically occurs between one and five years from diagnosis and the timing of this varies significantly according to the site of onset of ALS. There are significant variations in the timing of changes for individuals within these groupings and there are likely a larger number of groupings that would be clinically useful. A significant correlation between changes in speaking rate and intelligibility has been shown. Once changes to speech do start to occur then the time to the loss of functional speech appears relatively consistent across the types of ALS. Conclusion: Current best practice guidelines are not reflective of the findings of this review and do not support professionals in identifying how to provide timely support. Monitoring speech changes systematically may support timely intervention. There is potential for individual level predictive modeling to help support people living with ALS to be proactive and prepared for changes.","41744765":"ID: 41744765\nTitle: The Calcium Connection: Explaining Motor Neuron Vulnerability in ALS.\nAbstract: ALS is a severe neuromuscular disease classically characterized by the progressive loss of motor neurons, leading to incremental muscle weakness and eventually death. Current treatment options for ALS have proven to have limited effect, merely delaying the progression of symptoms and prolonging patient survival. This motor neuron subtype-related differential vulnerability has been linked to neuron excitability, metabolism, and protein aggregation. Calcium dysregulation, which serves as an important second messenger in neural signaling pathways, has been implicated in each of these mechanisms and represents a potential target for therapeutic intervention. Armed with cutting-edge tools for visualizing and recording calcium transients in vivo, ALS researchers have delved deeper into the role of calcium dysregulation in disease in recent years. Vulnerable motor neuron populations display an excess of calcium-permeable ion channels together with reduced expression of calcium-binding proteins, generating a cellular environment primed for excitotoxic stress. Loss of inhibitory synaptic input further heightens susceptibility to calcium overload. Paradoxically, some evidence suggests that elevated neuronal activity can exert neuroprotective effects, highlighting the complexity of activity-dependent calcium signaling in ALS. Additionally, ALS-related toxic protein accumulation disrupts calcium homeostasis, contributing to endoplasmic reticulum stress and mitochondrial dysfunction. Emerging data indicate that calcium dysregulation impairs neuron-glia communication, amplifying neuroinflammation and accelerating disease progression. This review aims to synthesize current evidence on how calcium imbalance contributes to motor neuron vulnerability and degeneration in ALS. By exploring the cellular, synaptic, and network-level mechanisms of calcium dysregulation in ALS, the review examines its interplay with mitochondrial and ER stress and explores its impact on neuron-glia interactions with the aim of synthesizing key mechanistic insights into the disease pathogenesis and therapeutic targets.","41765421":"ID: 41765421\nTitle: [Mechanism of action and clinical trial results of a new drug for amyotrophic lateral sclerosis (ALS), Mecobalamin (Rozebalamin®) for intramuscular injection, 25 mg].\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive, intractable neurodegenerative disease characterized by generalized muscle atrophy and weakness, dysarthria, dysphagia, and respiratory muscle paralysis. Respiratory dysfunction due to muscle weakness is the primary cause of death; without mechanical ventilation, death typically occurs within 2 to 5 years after onset. Mecobalamin, an active form of vitamin B12, is thought to suppress homocysteine-induced neuronal cell death in ALS by acting as a coenzyme for methionine synthase, which catalyzes the conversion of homocysteine to methionine. Since the 1990s, research on neurodegenerative diseases supported by Japan's Ministry of Health, Labour and Welfare has suggested that high-dose mecobalamin may confer clinical benefits in ALS. This led to the initiation of clinical development. A Phase II/III double-blind, placebo-controlled comparative trial was conducted, but did not meet its primary endpoint. Based on these trial findings, an investigator-initiated Phase III placebo-controlled, double-blind comparative trial was conducted primarily at Tokushima University Hospital, targeting patients who developed ALS within one year before starting the trial. The trial demonstrated the efficacy of high-dose mecobalamin in slowing the decline in the Revised ALS Functional Rating Scale total score, which was the primary endpoint. Safety was also confirmed. Based on these results, mecobalamin received regulatory approval in September 2024 for the indication \"slowing the progression of functional impairment in ALS.\" It is expected to offer a new treatment option for patients with ALS.","41784486":"ID: 41784486\nTitle: Exploring the use of narrative-based approaches in individuals with amyotrophic lateral sclerosis: A narrative review.\nAbstract: Narrative-based approaches have been utilized in medicine to better understand the illness experiences of individuals living with chronic conditions. In particular, people with amyotrophic lateral sclerosis (pALS) may benefit from use of narrative-based approaches, given the potential impact of progressive decline on identity of self. This review explores the use of narrative-based approaches in studies involving pALS to provide further insight to the experiences and psychosocial needs of this population. A search was conducted utilizing EMBASE, CINAHL, PsycInfo, and Google Scholar with several terms related to amyotrophic lateral sclerosis (ALS) and narrative-based approaches. Studies were included if they were written in English, incorporated methods that promoted the production of narratives, and reported data that could be clearly isolated to pALS. The search revealed a total of 154 articles for title and abstract screening. Fifty-two articles were selected for full-text review. Thirty-two articles met the criteria for data extraction. Four descriptive categories emerged upon examination of the narrative-based approaches implemented across the studies: psychosocial intervention, illness experience, intervention targeting specific needs, and secondary analysis of data. Some of the common themes identified across studies included: loss of physical and communicative function, adaptation to life changes, shifts in identity, and tension with the healthcare system. Despite the communication challenges that often coincide with disease progression, narrative-based approaches can be utilized in pALS. These approaches should be implemented to gain insight on the disease experiences of pALS, providing opportunity for patient-centered interventions to address the psychosocial needs of this population.","41827952":"ID: 41827952\nTitle: Motor Neuron Disease with Guillain-Barré Syndrome? Motor Band Sign with Anti-GQ1b Antibodies.\nAbstract: A 79-year-old former marathoner, with memory impairment since age 78, developed increasing stumbling and progressively worsening waddling gait. Three months after gait disturbance onset, she noted mild dysphagia. With declining walking distance and endurance, she presented to our hospital six months after onset, exhibiting frontal signs, Parkinsonism with marked trunk rigidity, and hyperreflexia of the jaw and limbs. L-dopa challenge tests showed no improvement. At seven months post-onset, she had difficulty rising. By nine months, she relied on a walker, and speech disturbance appeared. At 10-11 months, both dysarthria and dysphagia rapidly worsened, she became bed-ridden, and upper limb weakness developed (though she could still use chopsticks). Neurological examination at one year revealed severe dysarthria/dysphagia, four extremity fasciculations and muscle weakness (grade 2 in upper limbs, grade 1 in lower limbs), trunk-dominant rigidity, and hyperreflexia in the jaw and limbs. Brain MRI, specifically susceptibility-weighted imaging, revealed motor band signs. Cerebrospinal fluid study revealed albuminocytological dissociation. Needle electromyography revealed acute denervation and chronic reinnervation in the cranial nerve, cervical, and lumbar areas, which was suggestive of motor neuron disease (MND). Serum anti-GQ1b antibodies were detected. Immunotherapy was followed by mild improvement, which might suggest a reversible component, although definitive pathological overlap remains unconfirmed. This case highlights a diagnostic challenge where an acute immune-mediated neuropathy could potentially be superimposed on a chronic neurodegenerative process. Anti-GQ1b antibodies should be interpreted with caution, as they may reflect either a true clinicopathological overlap with Guillain-Barré syndrome or a secondary phenomenon (epiphenomenon) related to the primary neurodegenerative process.","41829459":"ID: 41829459\nTitle: Quantification of Tongue Motor Dysfunction in Amyotrophic Lateral Sclerosis Using a Smartphone-Based Task and Deep Learning.\nAbstract: Bulbar dysfunction is a major complication of amyotrophic lateral sclerosis (ALS). This study aimed to develop and validate a simple, smartphone-based task for the objective assessment of tongue movements and to examine their association with clinical variables. 37 ALS patients and 20 age- and sex-matched controls performed a tongue lateralization task, recorded with a smartphone. A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001). Normalized frequency was associated with dysarthria (t = -3.13, p = 0.003) but not dysphagia (t = -1.05, p = 0.30). Normalized frequency (t = 2.77, p = 0.009) and tongue \"spasticity\" (t = -2.57, p = 0.015) were both associated with speech performance in a multiple-regression model (R = 0.51, adjusted R2 = 0.43). Our method provides an objective, minimally invasive measure of bulbar function in ALS, which correlates with clinical ratings and may detect subtle impairments not captured by standard assessments. This approach offers a promising tool for remote monitoring and may support more effective disease management.","41838635":"ID: 41838635\nTitle: Comparing vowel intelligibility across interactive and non-interactive tasks in disordered speech.\nAbstract: The current study examines vowel intelligibility across interactive and non-interactive situations for individuals with dysarthria secondary to amyotrophic lateral sclerosis (PALS). The vowel space of these speakers is often characterized by centralization and lowering, negatively affecting intelligibility. In two experiments, listeners identified vowels produced by PALS in habitual speech (non-interactive), clear speech (non-interactive), and interactive matching. Clear speech and interactive matching elicited more intelligible vowels than habitual speech. Interactive matching productions were equal to or more intelligible than clear speech productions depending on vowel. These data represent a preliminary step to understanding how the dynamics of communicative interaction may shape vowel intelligibility.","41843813":"ID: 41843813\nTitle: ALS motor phenotypes: a revised 'OPM' classification.\nAbstract: Defining motor phenotypes in amyotrophic lateral sclerosis (ALS) is important for individualized care and optimal therapeutic trial design. The \"ALS-OPM\" classification is based on the onset region (O), the propagation of motor symptoms (P), and the degree of clinical upper (UMN) and/or lower (LMN) motor neuron dysfunction (M). An international ALS expert focus group was held in September 2025, followed by a consensus process through which revisions of the OPM classification were finalized. Onset (O1-4) identifies first motor symptoms as relating to the head (O1), distal/proximal arm (O2d/p), respiratory/axial trunk (O3r/a), or distal/proximal leg (O4d/p). Onset symptoms are defined by weakness or slowed, poorly coordinated voluntary movements in the muscles of the head, arm, trunk, or leg, including dysarthria, dysphagia, dysphonia, dyspnea, and axial instability. Propagation (P1(n)) or absence of propagation (P0(n)) of motor symptoms from the onset region to another body region are designated, where n denotes the number of months from onset to propagation or assessment. The degree of UMN dysfunction (slowed, poorly coordinated voluntary movements, hyperreflexia and/or spastic muscle tone, emotional lability) and/or LMN dysfunction (weakness with associated muscle atrophy) is classified as follows: balanced UMN and LMN dysfunction (M0); dominant (M1d) or pure UMN dysfunction (M1p); dominant (M2d) or pure LMN dysfunction (M2p); and dissociated UMN/LMN dysfunction (M3), in which the arms and legs predominantly show LMN and UMN involvement, respectively. The revised ALS-OPM classification aims to make it routine, practical and feasible to capture phenotype in clinical practice and therapeutic trials.","41892827":"ID: 41892827\nTitle: Biomechanical Voice Parameters as Potential Biomarkers for Phenotype Differentiation in Amyotrophic Lateral Sclerosis: A Cross-Sectional Study.\nAbstract: Background/Objectives: Amyotrophic lateral sclerosis (ALS) is a clinically heterogeneous neurodegenerative disease in which bulbar involvement frequently affects speech and voice production. Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS.","41905645":"ID: 41905645\nTitle: Six months of experience at a specialized daytime care center for people with amyotrophic lateral sclerosis (ALS) in the Community of Madrid.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease that affects motor neurons, leading to motor deterioration and a reduced quality of life. In the Community of Madrid, the ALS Network was established to improve patient care. In April 2024, the Specialised Day Care Centre for ALS (CEADELA) was inaugurated, complementing the care provided by the ALS Network. The aim of this study was to describe the experience of CEADELA during its first six months. A retrospective descriptive study was conducted on a cohort of CEADELA patients between April and October 2024. Clinical, functional, and therapeutic data were analysed, along with overall satisfaction levels. A total of 91 patients were included, with a mean age of 65.2 years (SD 11); of these, 59 (64.8%) were men. Most had spinal-onset ALS and were receiving treatment with riluzole. A significant increase was observed in the use of physiotherapy, speech therapy, and occupational therapy after referral to the centre. Functionality significantly declined over six months. The mortality rate was 12.1% (18.2% opted for assisted dying). Overall, 76 patients (83.5%) responded to the survey, with 100% reporting satisfaction or high satisfaction with the centre (80.2% very satisfied and 18.4% satisfied). CEADELA has improved access to specialised therapies with a high level of satisfaction, although disease progression remains a challenge. The need to continue developing integrated, evidence-based care models to optimise ALS management is highlighted.","41907197":"ID: 41907197\nTitle: Hereditary transthyretin amyloidosis mimicking ALS: First genetically proven case report from Saudi Arabia.\nAbstract: Hereditary transthyretin amyloidosis (ATTRv) is a systemic disorder that may mimic motor neuron disease (MND), leading to misdiagnosis and delayed access to disease-modifying therapies. We report the first genetically confirmed case of ATTRv mimicking amyotrophic lateral sclerosis (ALS) in Saudi Arabia. A 47-year-old male presented with progressive right-sided limb weakness (proximal > distal) and dysarthria over 18 months. Neurological examination revealed fasciculations, distal atrophy, and brisk reflexes with normal muscle tone and no spasticity. Electrophysiological studies demonstrated a length-dependent sensorimotor axonal neuropathy with widespread denervation changes involving bulbar, cervical, and lumbosacral regions. Brain and spine MRI, along with whole-body CT, excluded structural or paraneoplastic causes. Genetic testing identified a pathogenic heterozygous variant in the TTR gene: NM_000371.4:c.424G > A (p.Val142Ile). Transthoracic echocardiography revealed mild concentric left ventricular hypertrophy. There was no clinical evidence of autonomic, renal, or ocular involvement. This case underscores the importance of considering ATTRv in patients presenting with atypical MND, particularly when clinically significant sensory symptoms, absent upper motor neuron signs, or unexplained cardiac abnormalities are present. Early diagnosis enables access to targeted therapies such as TTR stabilizers and gene-silencing agents, which can alter disease trajectory.","41918982":"ID: 41918982\nTitle: Translating AI research into reality: summary of the 2025 voice AI Symposium and Hackathon.\nAbstract: The 2025 Voice AI Symposium represented a transition from conceptual research to clinical implementation in vocal biomarker science. Hosted by the NIH-funded Bridge2AI-Voice consortium, the meeting convened global experts to address the methodological, ethical, and translational challenges of integrating voice-based artificial intelligence (AI) into healthcare. This mini-review synthesizes symposium insights across six domains: multimodal integration, FAIR (Findable, Accessible, Interoperable, Reusable) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics) data governance, clinical translation, interdisciplinary training, and cross-sector innovation. Research presented demonstrated voice as a latent, multimodal biomarker reflecting neurological, cardiopulmonary, and psychological states, while discussions emphasized ethical data practices and human-centered design. The implementation-focused panels underscored the importance of workflow alignment and usability for adoption in real-world care. Collectively, the symposium reflects a field advancing toward translational readiness and ethical accountability, positioning voice AI as a scalable, inclusive tool for next-generation healthcare.","41919473":"ID: 41919473\nTitle: Long non-coding RNAs in neurodegenerative diseases - Molecular mechanisms, liquid biopsy biomarkers, and therapeutic targets: A review.\nAbstract: Neurodegenerative diseases (NDDs), such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), are age-related disorders characterized by progressive neuronal loss, cognitive decline, and limited options for disease-modifying treatments. Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication. Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles. Additionally, lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms. Overall, lncRNAs have emerged as central molecular regulators and promising candidates for translation in NDDs. Nonetheless, challenges related to specificity, validation, delivery across the blood-brain barrier, and clinical standardization must be addressed before their routine application in precision neurology.","41920737":"ID: 41920737\nTitle: Decoding intended speech with an intracortical brain-computer interface in a person with long-standing anarthria and locked-in syndrome.\nAbstract: Intracortical brain-computer interfaces (iBCIs) for decoding intended speech have provided individuals with ALS and severe dysarthria an intuitive method for high-throughput communication. These advances have been demonstrated in individuals who are still able to vocalize and move speech articulators. Here, we decoded intended speech from an individual with long-standing anarthria, locked-in syndrome, and ventilator dependence due to advanced symptoms of ALS. We found that phonemes, words, and higher order language units could be decoded well above chance. While sentence decoding accuracy was below that of demonstrations in participants with dysarthria, we attained an extensive characterization of neural signals underlying speech in a person with locked-in syndrome and identify directions for future improvement. These include closed-loop speech imagery training and decoding linguistic (rather than phonemic) units from neural signals in middle precentral gyrus to augment decoding at the sentence level. These results demonstrate that usable speech decoding from motor cortex may be feasible in people with anarthria and ventilator dependence.","41925483":"ID: 41925483\nTitle: Neuroimaging confirms selective cerebral involvement in primary lateral sclerosis and predilection to brain regions with high metabolic activity.\nAbstract: Primary lateral sclerosis (PLS) is a low incidence motor neuron disease manifesting in progressive limb spasticity, gait impairment, bulbar dysfunction and often in pseudobulbar affect. Varying degree of frontotemporal involvement has also been recently confirmed. Postmortem data is scarce in PLS and disease burden patterns are best characterised in vivo by purpose-designed neuroimaging protocols. A large prospective neuroimaging study has been undertaken to explore cerebral involvement patterns in PLS using a both structural T1-weighted data and diffusion MRI data. Neuroimaging data were complemented by genetic screening and comprehensive clinical profiling. Brain involvement patterns have been first characterised by standard morphometric and diffusivity analyses. Resulting disease burden maps were then correlated to physiological mitochondrial density (MitoD) maps. In an additional, region-of-interest analysis, brain regions with significant topological associations between neurodegeneration and MitoD were ranked based on their r-values. Grey matter degeneration in PLS is not limited to the motor cortex, but also encompasses frontotemporal, caudate, thalamic, cerebellar and cingulate regions. Voxelwise statistics confirm topological associations between atrophy and physiological mitochondrial density. The most significant associations between neurodegeneration and MitoD were detected in the cerebellum, superior temporal lobe, precentral gyrus, inferior operculum, and orbitofrontal gyrus. Similarly, white matter degeneration is not limited to the corticospinal tracts, but includes the corpus callosum, frontotemporal association fibres, the cingulum, cerebellar peduncles, and the fornix. Anatomical associations were also detected between diffusivity alterations and focal MitoD. PLS is associated with a selective disease burden pattern, and our data suggest that brain regions with high baseline metabolic activity are more likely to succumb to neurodegeneration. Cerebral areas showing the most significant anatomical associations between atrophy and mitochondrial density (precentral gyrus, cerebellum, frontotemporal regions) are pathognomonic brain regions of PLS driving its core clinical manifestations.","41928799":"ID: 41928799\nTitle: Stable speech BCI performance during slow progression of ALS: A longitudinal ECoG study.\nAbstract: Electrocorticographic (ECoG) speech brain-computer interfaces (BCIs) show promise for restoring communication in amyotrophic lateral sclerosis (ALS), but the long-term stability of speech-related neural signals and decoding performance during disease progression remains unclear. We tracked signal characteristics and decoding over 25 months in a participant with ALS to determine how high-gamma (HG, 70-170 Hz) activity changes over time and whether these changes affect offline speech decoding. We implanted two 8×8 subdural ECoG grids over left sensorimotor cortex (SMC) in a participant with slowly progressive bulbar variant ALS. Across 25 months, the participant performed an overt syllable-repetition task (12 consonant-vowel tokens) during simultaneous ECoG and audio recording. We quantified HG activation ratio (ActR), spectral signal-to-noise ratio (SNR; HG/HF, where HF = 300-499 Hz), and peak z-scored HG responses. Speech acoustics were evaluated using first/second formants (F1/F2) and the triangular vowel space area (tVSA). Offline EEGNet-based decoders were assessed in two stages: models trained on post-implant months 1-6 were tested on months 7-25, while models trained on stabilized data (months 7-11) were tested on the remaining period (months 12-25). Electrode-level saliency assessed spatial contributions to decoding. Acoustic analyses showed a significant reduction in tVSA over two years (-44.6 Hz2/day; P < 10-7), consistent with mild intelligibility decline. Neural metrics (ActR and SNR) followed a biphasic trajectory: increasing during the first 6 months, after which ActR stabilized (0.041%/day; P = 0.13), and SNR declined gradually (-0.46%/day, P < 10- 4). The model trained on months 1-6 achieved 55.7% accuracy (chance: 8.33%), but performance declined over time (-0.019%/day; P = 2.1×10-4). Conversely, the model trained on months 7-11 achieved higher accuracy (65.9%) on subsequent data with no significant temporal decline (P = 0.23). Speech-related HG features exhibited an initial unstable period followed by a long-term gradual SNR reduction, potentially reflecting disease progression. Models trained after signal stabilization generalized robustly to data recorded over a year later. These findings confirm that despite reduced absolute HG power and mild acoustic degradation of speech, cortical features remain stable enough to support durable ECoG speech BCIs without frequent recalibration. These findings will motivate future adaptive calibration algorithms that account for slow signal changes while leveraging stable spatial representations in ventral SMC.

Fifty-four participants with ALS were enrolled and participated in an 8-week pretreatment run-in, followed by three 8-week dosing periods and an 8-week follow-up. They completed a speech assessment every two weeks in the clinic or at home. We observed moderate to high correlations between digital measures of speech timing and articulatory motor function, and the ALS Functional Rating Scale-Revised, slow vital capacity and plasma neurofilament light chain. Furthermore, speech measures can show functional decline before the ALSFRS-R does, while also capturing differences between participants with bulbar symptoms and those without. The results support the feasibility and utility of digital speech endpoints to study disease impact in ALS clinical trials.","42011674":"ID: 42011674\nTitle: Speech and swallow outcome measures for ALS and perspectives on remote monitoring: an international survey of speech & language therapists.\nAbstract: Dysarthria and dysphagia occur frequently in Amyotrophic Lateral Sclerosis (ALS). To manage these symptoms, speech & language therapists (SLTs) must identify relevant speech and swallow outcomes and select suitable outcome measurement instruments. Remote monitoring is an evolving mode of health status tracking. This survey aimed to establish SLT perspectives on ALS assessment regarding 1) the clinical meaningfulness of existing outcome measurement instruments 2) remote monitoring 3) usefulness of assessment devices for patient care and 4) bulbar function outcomes and measurement instruments useful for research studies. An online English-language survey was distributed internationally through gatekeepers and social media. Sixty-six SLTs responded from 13 countries. Current outcome measurement instruments were regarded as clinically meaningful in ALS by 35% for speech and 41% for swallow. Only 12% had access to remote monitoring, but 77% would like to avail of it, with 58% perceiving its potential to enhance care. Eighty-two percent deemed remote monitoring using digital patient-reported outcome measures (PROMs) useful. Speech intelligibility measurement was selected as the most useful communication outcome for remote monitoring (92%) and research (94%). SLTs agreed that speech intelligibility test software (72%), smart device apps (70%) and tongue pressure measurement devices (54%) are useful assessment equipment. SLTs want better measurement instruments for speech and swallow in ALS. They regarded technologies including remote monitoring incorporating digital PROMs as useful. Outcomes reflecting communication and swallow functional success level were deemed most useful. These survey findings can inform the selection of digital speech and swallow outcomes for ALS.","42051912":"ID: 42051912\nTitle: Amyotrophic lateral sclerosis and chronic inflammatory demyelinating polyneuropathy coexistence in a patient with a C9orf72 variant: case report.\nAbstract: The C9orf72 variation has been strongly implicated in the inheritance of familial ALS, frontotemporal dementia (FTD), and combined ALS-FTD cases. Increasing evidence implicates immune changes and inflammation in some ALS patients. Several studies demonstrated that ALS coexists with CIDP or polyneuropathy. Mouse models of C9orf72 loss-of-function mutations exhibit fatal immune dysregulation. A 62-year-old Caucasian man developed right foot drop, and he underwent fibular nerve release without significant improvement. At the same time, he developed progressive weakness and numbness in his bilateral hands. MRI revealed cervical canal stenosis and neuroforaminal narrowing that prompted neurosurgical decompression without clinical improvement. Subsequently, he developed left foot drop. At the clinic presentation, he exhibited dysarthria, tongue fasciculations, weakness in all extremities, muscle atrophy, widespread fasciculations, and upper extremity hyperreflexia, meeting clinical criteria for ALS. Genetic testing identified a pathogenic variant in the C9orf72 gene, confirming a C9orf72 variant, commonly linked to familial ALS. Brain MRI demonstrated the motor band sign. Although EMG/NCS findings were consistent with lower motor neuron disease, he also had signs of demyelinating polyneuropathy based on conduction parameters. Neuromuscular ultrasound showed significant multifocal nerve enlargement typical of immune-mediated neuropathy. CSF studies revealed albuminocytologic dissociation (protein: 112 mg/dL, with normal cell count) and high albumin quotient and index. He fulfilled the 2021 EAN/PNS criteria for possible typical CIDP. He was treated with intravenous immunoglobulin in addition to riluzole with temporary improvement. This is the first case of the co-existence of CIDP and ALS in the setting of a pathogenic C9orf72 variant.","42074898":"ID: 42074898\nTitle: Slower Progression Rates in Lower Limb-Onset ALS.\nAbstract: Objectives: The aim of this study was to assess the differences in diagnostic delay and disease progression in people with ALS (PALS) based on site of onset. Methods: A retrospective analysis of prospectively collected data was performed, including all PALS seen in the ALS clinic in the Hadassah Medical Center between January 2009 and March 2022. PALS were divided to three groups based on site of onset (upper limb onset-ULO, lower limb onset-LLO, or bulbar onset-BO). A linear mixed-effects model was constructed with the following variables: diagnostic delay, site of onset, age of onset and time since the initial visit. The model was applied to the ALSFRS-R total score and the bulbar and motor subscales. Results: Data from 1255 visits of 281 PALS were included in the study. PALS with LLO had longer diagnostic delays than PALS in the BO group. Slower decline of total ALSFRS-R score was observed in younger PALS, and in PALS with LLO when compared with PALS with BO or ULO. The slower decline of ALSFRS-R in PALS with LLO was due to a slower decline in the motor subscale. Longer diagnostic delays were associated with lower total ALSFRS-R scores at the initial visit and with slower rates of decline. Conclusions: Comparison among PALS with ULO, LLO and BO revealed differences in the diagnostic delay and in the rate of functional decline, suggesting that differentiating between ULO and LLO ALS may be useful in the stratification of PALS in clinical trials.","42084465":"ID: 42084465\nTitle: Lexical Properties of Stimuli in Standardized Articulation and Phonology Tests: A Short Report.\nAbstract: The purpose of the present study was to report the phonological neighborhood density, phonotactic probability, and word frequency of the stimuli in 12 commonly used articulation and/or phonological tests. We extend the work of Macrae (2017), who identified variability in stimulus items across consonant singletons, consonant clusters, vowels, phoneme complexity, and bound morpheme. This study sought to augment that work with a deeper analysis of lexical and sublexical features of these stimuli. The stimuli from 12 articulation and/or phonological tests were extracted, resulting in 667 stimuli. All stimuli were run through a phonological neighborhood density and phonotactic probability calculator. Word frequency was determined using Moe et al.'s (1982) database. Means and ranges for all lexical characteristics were computed across each of the 12 tests. Most stimuli were from sparse phonological neighborhoods, and included common sound sequences. Although the average word frequency value was in the high range, overall, very few test stimuli were high-frequency words. There was not one articulation and/or phonological test that considered or balanced these three lexical properties. We discuss the linguistic constraints surrounding developing such a test. We also discuss future research opportunities to examine if these lexical properties may result in over- and underidentification of children with speech sound disorders.","42091714":"ID: 42091714\nTitle: The Dysphagia Outcome and Severity Scale (DOSS) and non-instrumental swallowing measures in amyotrophic lateral sclerosis.\nAbstract: To evaluate reliability of the Dysphagia Outcome and Severity Scale (DOSS) in Amyotrophic Lateral Sclerosis (ALS) patients, and to assess diagnostic accuracy of selected non-instrumental measures in defining swallowing safety in this population. One hundred and thirteen consecutive ALS patients underwent comprehensive dysphagia evaluation with fiberoptic endoscopic evaluation of swallowing (FEES) and were classified according to DOSS. Safe and unsafe swallowing were defined by DOSS levels 7-6 and 5-1, respectively. Patient-reported measures included ALS Functional Rating Scale-Revised swallow item (I-3) and Eating Assessment Tool-10 (EAT-10). Non-instrumental clinical measures were hyolaryngeal excursion, voluntary cough (VC), voice quality and reflexive cough/throat clearing (VRC), and maximum phonation time (MPT). Inter- and intra-rater reliability were assessed using weighted Cohen's kappa and Fleiss' kappa coefficients. Non-instrumental measures diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis. Twenty-six of 113 patients (23%) exhibited an unsafe swallowing. Inter- and intra-rater agreement for DOSS classification was excellent across raters. EAT-10 and a composite clinical index derived from VC, VRC, and MPT showed the highest diagnostic accuracy with area under the curve values of 0.790 and 0.832, respectively. Other non-instrumental measures demonstrated lower discriminative performance. The DOSS showed an excellent reliability when applied to FEES in patients with ALS, supporting its use as a functional classification tool with direct nutritional and management implications. Non-instrumental measures should be interpreted with caution and confined to a triage role rather than diagnostic decision-making, particularly in light of the rapid progression of dysphagia in ALS.","42113599":"ID: 42113599\nTitle: Amyotrophic Lateral Sclerosis: A Review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive weakness due to degeneration of upper motor neurons in the brain and lower motor neurons in the brainstem and spinal cord. It affects approximately 25 000 individuals in the United States. Amyotrophic lateral sclerosis is characterized by progressive painless muscle weakness that typically begins in a focal region of the body, such as limb muscle weakness causing hand weakness or foot drop (65%), cranial muscle weakness causing speech or swallowing problems (20%-25%), or axial muscle weakness causing bent posture (5%-10%), and spreads to other body regions over time. The disease usually manifests with dysfunction indicative of both upper motor neurons (causing muscle stiffness and spasticity) and lower motor neurons (causing weakness, fasciculations, atrophy, and flaccidity). After onset, weakness spreads through the musculature and typically causes death due to respiratory muscle weakness. Among people with ALS, approximately 85% have sporadic ALS, which is not associated with known environmental or genetic factors, and 15% have familial ALS. Amyotrophic lateral sclerosis is diagnosed based on clinical features, which can be supported by results of electromyography. More than 60 genes have been associated with ALS, and most are autosomal dominant. Pathogenic variants in chromosome 9 open reading frame 72 (C9orf72) are found in 40% of all familial ALS cases, and pathogenic variants in superoxide dismutase 1 (SOD1) are found in 20% of patients with familial ALS. Patients with ALS survive a mean of 3 to 5 years after diagnosis, and there are currently no curative therapies. Clinical care primarily focuses on symptom management and quality of life. Three US Food and Drug Administration (FDA)-approved disease-modifying therapies are available in the United States. Riluzole and edaravone are oral medications that slow ALS progression by up to 2 to 4 months, and tofersen is an intrathecally administered gene therapy for patients with SOD1 gene variants. Specialized multidisciplinary teams, comprising neurologists, nurses, therapists, dietitians, and social workers, are associated with improved survival (4-7 months) and quality of life. Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disorder of upper and lower motor neurons. No curative therapies exist. Two oral medications, riluzole and edaravone, are approved by the FDA and modestly decrease disease progression in sporadic ALS. Tofersen, an intrathecally administered gene-based therapy, is also FDA approved and slows disease progression in patients with SOD1 pathogenic gene variants.","42137113":"ID: 42137113\nTitle: An interpretable, clinically grounded framework for digital speech biomarker development in neurodegenerative diseases.\nAbstract: Communication ability-a key determinant of quality of life-is frequently affected and progressively declines in neurodegenerative diseases. Effective management of progressive communication disorders requires a personalized approach to deliver timely interventions tailored to the evolving profiles of communicative impairment, thereby supporting functional communication throughout the disease course. To this end, reliable tools capable of detecting and quantifying both disease-specific patterns of communicative impairment and within-disease phenotypic variability are urgently needed. This study leverages Artificial Intelligence and advanced data analytics to develop an acoustic-based framework for automated extraction of interpretable, clinically grounded speech markers to enable objective assessment and phenotyping of progressive communication disorders. Three groups of participants, including 14 individuals with amyotrophic lateral sclerosis (ALS) and 15 individuals with Parkinson's disease (PD), alongside 10 neurologically healthy controls, performed a standardized oral passage reading task, yielding 739 speech samples. Fifty acoustic features were extracted using an automated analytic pipeline and subsequently clustered into six interpretable composite markers. The clinical utility of these markers was evaluated with the recorded speech samples by examining their (1) associations with standardized metrics of cognitive, motor speech, and overall communicative functions, (2) efficacy for detecting and differentiating disease-specific communicative impairment patterns in ALS and PD using supervised machine learning, and (3) utility for within-disease phenotyping and stratification using unsupervised clustering analysis. The markers effectively (1) detected subtle subclinical changes across multiple domains prior to substantial declines in functional communication outcomes; (2) differentiated disease-specific patterns of communicative impairment (multiclass area under the curve > 0.90); and (3) identified subgroups with distinct speech profiles within each disease. The findings support the potential of the proposed framework as a clinically translatable, objective tool to facilitate early detection, differential diagnosis, and phenotyping of progressive communication disorders, ultimately advancing personalized, measurement-based care in neurodegenerative diseases.","42151746":"ID: 42151746\nTitle: Perceptions of Speech-Language Pathology Care in Amyotrophic Lateral Sclerosis: A Patient-Centered Exploratory Study.\nAbstract: Given limited research on patient perspectives of speech-language pathology (SLP) services in ALS care, this study aimed to assess the satisfaction with, and understanding of, SLP services by people with ALS (pwALS) and to examine the alignment between services received and patient-reported impairments. A cross-sectional survey assessing pwALS' perceptions of SLPs was distributed from October 2024 to January 2025 through electronic mailing lists of relevant professional organizations. A questionnaire examined pwALS' understanding of the SLP role, satisfaction levels, alignment between patient-reported impairments and SLP interventions, and perceived gaps in care. Responses were analyzed using descriptive statistics, with open-ended items analyzed using qualitative analysis. The 81 survey respondents consisted of pwALS (81.5%), caregivers (11.1%), family members (4.9%), and others (2.5%). Overall satisfaction with SLP care was high, though open-ended responses revealed gaps in understanding. Many were unaware of the full scope of SLP services; only 17.3% recognized cognitive evaluation and 8.6% cognitive therapy, compared with speech (77.8%) and swallowing (81.5%) evaluations. Reported services often did not align with communication and swallowing needs, but patients educated about a service were significantly more likely to use it. Overall satisfaction with SLP care was high; however, open-ended responses revealed gaps in understanding, unmet needs, and limited awareness of the full scope of SLP services. This misalignment highlights the need for improved patient and caregiver education regarding the role and timing of SLP involvement to enhance engagement, appropriate service use, and outcomes in ALS care.","42152867":"ID: 42152867\nTitle: The effects of a mobile healthcare application on speech and swallowing in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) impairs oral motor function, negatively affecting patients' speech and swallowing abilities, as well as quality of life. This study aims to evaluate the effectiveness of A Successful Swallowing with Effortful Training (ASSET) program, included in the 'The 365 Healthy Swallow Health Coach application' in preserving speech and swallowing abilities in ALS patients through self-training. In this 8-week quasi-experimental study, 13 participants were allocated to either the app-guided ASSET training group (n=7; three sessions per day, five days per week) or a usual-care control group (n=6) based on their clinical visit schedules. To evaluate changes over time and compare the two groups, linear mixed models were employed. Changes in ALS severity scale (ALSSS), Diadochokinetic (DDK) task, speech intensity, Speech Handicap Index-15, Dysphagia Handicap Index, Swallowing Quality of Life (SWAL-QOL), and Brief Inventory of Swallowing Assessment-15 were assessed. ALSSS speech scores was relatively preserved from 5.43 (95% CI 3.01-7.84) to 5.29 (95% CI 2.87-7.70) in the ASSET treatment group, but declined from 6.33 (95% CI 3.73-8.94) to 4.83 (95% CI 2.23-7.44) in the control group, with a significant group-by-time interaction (p=.017). DDK/tuh/and/kuh/were relatively preserved from 11.86 to 11.71 and from 12.29 to 11.57 respectively in ASSET group, but declined from 11.67 to 7.50 and from 11.83 to 7.17 in the control group, with significant interactions in/tuh/(p=.032) and/kuh/(p=.044). SWAL-QOL total score was relatively preserved from 155.86 to 149.71 in ASSET group, but declined from 154.67 to 125.17 in the control group, with a significant interaction (p=.011). The findings suggest that ASSET program may help preserve speech and swallowing function in patients with ALS. Future research should validate the ASSET program with a larger, adequately powered sample size.","42166520":"ID: 42166520\nTitle: Clinical characterization and natural history of ALS8/VAPB p.Pro56Ser: upper motor neurone signs, survival, and functional milestones in 78 patients.\nAbstract: Amyotrophic lateral sclerosis type 8 (ALS8), caused by the VAPB p.Pro56Ser mutation, is a rare familial motor neurone disease with an incompletely characterized profile. We aimed to characterize the clinical phenotype, upper motor neurone (UMN) sign prevalence, survival, and functional milestones. We retrospectively analyzed 78 patients with ALS8 confirmed via molecular testing or familial linkage analysis from 57 apparently unrelated families. UMN signs were assessed using a five-item composite of pyramidal signs. Survival and milestones were estimated using Kaplan-Meier analysis. Median age at onset was 44.9 years; 51% were men. Onset was lumbar in 94%, proximally predominant. UMN signs were present in 53 patients; none exhibited clonus. At admission, 51% had spinal-onset ALS, 42% progressive muscular atrophy (PMA) and 6% flail leg; 30% of patients with PMA subsequently developed UMN signs. Survival was 21.9 years; times to wheelchair dependence and noninvasive ventilation were 7.0 and 10.0 years, respectively. Bulbar involvement occurred in 17 (21.8%) patients, predominantly as dysphonia. UMN status did not affect survival (p = 0.312). The standardized mortality ratio was 4.54 (95% CI 2.77-7.01), supporting disease-related excess mortality. ALS8 is a slowly progressive motor neurone disease with lumbar onset, ascending progression, and frequent but subtle UMN signs. Survival was markedly prolonged but functional decline followed a predictable sequence. These findings expand the phenotypic characterization of ALS8 and support genetic counseling and anticipatory management.","42167272":"ID: 42167272\nTitle: Updated trends in the global prevalence and burden of mental disorders, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: The 2023 iteration of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) estimated prevalence, incidence, and health burden for 375 diseases and injuries, including 12 mental disorders. We assess past, current, and emerging trends in the prevalence and burden of mental disorders across sexes and age groups, for 21 regions, 204 countries and territories, and by Socio-demographic Index (SDI) quintile, from 1990 to 2023. Mental disorders included in GBD 2023 were anxiety disorders, major depressive disorder, dysthymia, bipolar disorder, schizophrenia, autism spectrum disorders, conduct disorder, attention-deficit hyperactivity disorder, anorexia nervosa, bulimia nervosa, idiopathic developmental intellectual disability, and a residual category of other mental disorders. A literature review identified epidemiological data for each disorder. These were analysed via a Bayesian meta-regression to estimate prevalence by disorder, sex, age, location, and year. Disorder-specific prevalence was multiplied by disability weights representing the severity of health loss associated with each disorder to estimate years lived with disability (YLDs). Deaths due to anorexia nervosa were assessed with a Cause of Death Ensemble modelling strategy to estimate deaths by sex, age, location, and year, and then multiplied by the standard life expectancy at age of death to estimate years of life lost (YLLs). YLDs equalled disability-adjusted life-years (DALYs) for all mental disorders except anorexia nervosa (the only mental disorder considered as an underlying cause of death in GBD), for which DALYs represented the sum of YLDs and YLLs. We presented prevalence, deaths, YLDs, YLLs, and DALYs as counts, age-specific rates per 100 000 population, and age-standardised rates per 100 000 population. We estimated 1·17 billion (95% uncertainty interval 1·06-1·31) prevalent cases of mental disorders globally in 2023, equivalent to an age-standardised prevalence rate of 14 210·7 cases (12 849·5-15 940·1) per 100 000 population. These estimates represented a 95·5% (75·0-121·2) increase in prevalent cases and 24·2% (11·4-41·4) increase in age-standardised prevalence rate between 1990 and 2023. All mental disorders showed increases in prevalent cases between 1990 and 2023, while notable increases were seen in age-standardised prevalence rates for anxiety disorders, major depressive disorder, dysthymia, anorexia nervosa, bulimia nervosa, schizophrenia, and conduct disorder. There were an estimated 171 million (127-228) DALYs due to mental disorders globally across sex and age in 2023, equivalent to an age-standardised DALY rate of 2070·5 DALYs (1519·1-2750·5) per 100 000 population. Mental disorders contributed to 6·1% (4·8-7·6) of all-cause DALYs in 2023, making them the fifth leading cause of global DALYs (up from 12th in 1990). DALYs were almost entirely composed of YLDs. Mental disorders were the leading cause of YLDs in 2023 (up from second in 1990), explaining 17·3% (14·8-20·6) of all-cause global YLDs. Leading causes of mental disorder DALYs were anxiety disorders (ranked 11th among the 304 diseases and injuries at Level 4 of the GBD cause hierarchy), major depressive disorder (15th), and schizophrenia (41st). Globally in 2023, mental disorder age-standardised DALY rates were higher among females (2239·6 [1643·7-3014·1] per 100 000) than among males (1900·2 [1399·8-2510·8] per 100 000), and peaked in the 15-19 years age group (2617·3 [1850·6-3696·8] per 100 000). All locations showed increased mental disorder DALY rates in 2023 compared with 1990, ranging across countries and territories from 1302·4 (952·7-1683·7) per 100 000 in Viet Nam to 3555·8 (2661·9-4715·0) per 100 000 in the Netherlands. Across SDI quintiles, DALY rates ranged from 1853·0 (1352·1-2469·3) per 100 000 for middle SDI to 2184·1 (1606·1-2890·3) per 100 000 for high SDI. A significant health burden was imposed by mental disorders in all countries and territories in 2023, irrespective of the health resources available. In some instances, this burden has increased over time and is unevenly distributed across populations. Stronger surveillance systems, particularly in low-income and middle-income countries, are required. Additionally, we need more coordinated and inclusive policies to reduce the burden through early treatment and prevention, tailored to sex and age differences across locations. Responding to the mental health needs of our global population, especially those most vulnerable, is an obligation, not a choice.

In this paper, we introduce a data-driven approach to support the characterization of ALS phenotypes based on clinical data from a battery of examinations. A consensus clustering method is proposed to identify stable clusters across multiple random data sub-samples, with the objective of discovering whether the retrieved patients' groups and related features align with clinical phenotypes and medical knowledge. Results suggest consistent profiles for bulbar onset ALS patients, driven by onset characteristics, whereas spinal onset ALS patients exhibit greater within-phenotype heterogeneity.","42185781":"ID: 42185781\nTitle: Association between creatinine-to-cystatin C ratio and ALSFRS-R across clinical phenotypes.\nAbstract: Reliable and accessible biomarkers for amyotrophic lateral sclerosis (ALS) are scarce. Creatinine (Cre) reflects muscle mass, whereas cystatin C (CysC) may reflect neurodegeneration without being directly influenced by muscle mass; however, both have limitations. We aimed to investigate whether the creatinine-to-cystatin C ratio (Cre/CysC) was cross-sectionally associated with functional status in patients with ALS. We retrospectively analyzed 30 patients diagnosed with ALS at the National Organization Hospital Okinawa Hospital between 2021 and 2024. Baseline ALS Functional Rating Scale-Revised (ALSFRS-R) scores and serum Cre and CysC levels were recorded. Associations with the ALSFRS-R were assessed using Spearman's correlation, with subgroup analyses by sex, site of onset, age at diagnosis, body mass index (BMI), and diagnostic delay. Multivariable analyses were performed to examine the independent association between Cre/CysC and ALSFRS-R while accounting for relevant clinical covariates. Cre/CysC showed a stronger cross-sectional correlation with ALSFRS-R (rs=0.648, p = 0.0001) than Cre alone (rs =0.427) or CysC (rs =-0.119). Exploratory subgroup analyses showed generally positive associations in several subgroups, although no statistically significant association was observed in the small bulbar-onset subgroup. In multivariable analysis adjusted for age at onset and diagnostic delay, Cre/CysC remained independently associated with ALSFRS-R (β = 20.1, 95% CI 6.41-33.9, p = 0.006). Given the small sample size and cross-sectional design, these findings should be interpreted as exploratory. Cre/CysC showed a stronger cross-sectional association with functional status than either marker alone. Because it is derived from routine laboratory tests, Cre/CysC may represent a simple exploratory measure associated with functional status in ALS. However, the present findings do not establish prognostic utility or fully account for disease stage and biological heterogeneity. Prospective longitudinal studies incorporating disease progression measures and broader clinical and genetic characterization are warranted.","42187452":"ID: 42187452\nTitle: Assessment of Respiratory Rate and Simulated Apnea Utilizing the PneumoWave Biosensor: In Vitro and In Vivo Validation.\nAbstract: Accurate monitoring of respiratory rates is critical for early detection of a range of clinical conditions. However, standard manual counting or inadequate clinical monitoring often fails to provide reliable measurements. This study evaluated and validated the PneumoWave biosensor for respiratory rate measurement across a broad physiological range and different body postures (45°, 90°, and 180°) in both in vitro and in vivo settings. In vitro validation was performed using a SimMan ALS manikin operated at respiratory settings of 6-30 breaths per minute, with 10 s periods of simulated apnea. In vivo validation involved 20 healthy volunteers performing metronome-guided breathing while wearing bilateral PneumoWave biosensors. In vitro results demonstrated an excellent correlation between biosensors and manikin respiratory settings and captured all apnea events (r = 0.99, ICC = 0.99). In vivo findings showed good agreement with direct observational count (r = 0.99, R2 = 0.99, ICC = 0.99), with 97% of apnea events captured by both devices in all positions. Body postures had no significant impact on biosensor accuracy. These findings demonstrate that the PneumoWave biosensor provides accurate and reliable respiratory monitoring and supports its potential as a robust, non-invasive tool for continuous clinical and remote patient monitoring.","42191539":"ID: 42191539\nTitle: Discovering Hidden Vocal Subtypes: An Unsupervised Acoustic-Biomechanical Exploration of Voice Profiles.\nAbstract: This study aims to explore latent acoustic-biomechanical patterns of voice production using an unsupervised multivariate approach, and to identify data-driven vocal profiles across individuals with amyotrophic lateral sclerosis (ALS) and nonneurological dysphonia. A cross-sectional sample of 100 individuals, including patients with ALS and individuals with nonneurological dysphonia, was analyzed. Sustained vowel phonation was recorded and characterized using 26 variables, including standard acoustic measures (fundamental frequency -fo-, jitter, shimmer, and harmonics-to-noise ratio (HNR)) and 22 biomechanical parameters. Principal component analysis was applied to investigate relationships among variables and reduce dimensionality. Unsupervised clustering was performed at both the variable level to identify functional groupings and the participant level to derive data-driven voice profiles. Cluster validity was assessed using internal indices. Post hoc statistical comparisons and chi-square tests were used descriptively to characterize between-cluster differences and their relationship with clinical categories. The first five principal components explained 70.7% of the total variance, revealing structured relationships between acoustic and biomechanical features. Participant level clustering consistently supported a two-profile solution. Fifteen voice parameters differed significantly between profiles after false discovery rate correction, with the largest effects observed for shimmer, HNR, and the biomechanical parameter Pr11, reflecting differences in vocal stability and noise-related characteristics. The identified profiles were not significantly associated with clinical diagnostic categories. An unsupervised multimodal analysis of sustained phonation revealed two coherent vocal profiles that transcend traditional diagnostic labels. These data-driven voice phenotypes may capture functional patterns of voice production and support future efforts toward more refined and personalized characterization of voice disorders.","42201356":"ID: 42201356\nTitle: [Hereditary breast cancer : Syndromes, pathology, clinical aspects].\nAbstract: Approximately 5-10% of all breast cancers arise from a hereditary predisposition. In addition to the high-risk genes BRCA1 and BRCA2, other genes involved in homologous recombination repair (including PALB2, ATM, CHEK2, RAD51C/D, BARD1) and genes associated with classic tumor predisposition syndromes (TP53, PTEN, STK11, CDH1, NF1) are associated with an increased risk of breast cancer. In addition, polygenic risk contributes to the individual probability of developing the disease through the additive effect of numerous low-penetrance variants.Pathology can contribute significantly to the identification of patients with possible hereditary tumorigenesis. Certain morphological and immunohistochemical features may indicate a genetic background-for example, a lymphocyte-rich, triple-negative phenotype, G3, with medullary features may indicate a BRCA1 mutation, or an invasive lobular carcinoma may indicate a CDH1 mutation. Clinical constellations such as early age of onset, bilateral tumors, associated tumors, or familial clustering are also important indicators.The identification of a germline mutation has far-reaching consequences for the affected individual and the entire family. Intensive follow-up care programs are offered to those affected; risk-reducing surgery may be considered for mutations in certain risk genes. There are also therapeutic implications, such as the use of PARP inhibitors in BRCA1/2-associated HER2-negative breast cancer. Predictive genetic testing may be considered for relatives as well as intensified early detection programs and risk-reducing surgery, if necessary.Close interdisciplinary cooperation is therefore crucial in order to identify patients with possible hereditary tumorigenesis at an early stage and to enable an individualized therapy and follow-up care strategy. Etwa 5–10 % aller Mammakarzinome entstehen auf dem Boden einer hereditären Prädisposition. Neben den Hochrisikogenen BRCA1 und BRCA2 sind weitere Gene der homologen Rekombinationsreparatur (u. a. PALB2, ATM, CHEK2, RAD51C/D, BARD1) sowie Gene klassischer Tumorprädispositionssyndrome (TP53, PTEN, STK11, CDH1, NF1) mit einem erhöhten Brustkrebsrisiko assoziiert. Darüber hinaus trägt ein polygenes Risiko durch die additive Wirkung zahlreicher niedrigpenetranter Varianten zur individuellen Erkrankungswahrscheinlichkeit bei.Die Pathologie kann wesentlich zur Identifikation von Patientinnen mit möglicher hereditärer Tumorgenese beitragen. Bestimmte morphologische und immunhistochemische Merkmale können auf einen genetischen Hintergrund hinweisen – etwa ein lymphozytenreicher, triple-negativer Phänotyp, G3, mit medullären Eigenschaften auf eine BRCA1-Mutation oder ein invasives lobuläres Karzinom auf eine CDH1-Mutation. Auch klinische Konstellationen wie frühes Erkrankungsalter, bilaterale Tumoren, assoziierte Tumoren oder familiäre Häufung sind wichtige Hinweise.Die Identifikation einer Keimbahnmutation hat weitreichende Konsequenzen für die Betroffene sowie die gesamte Familie. Betroffenen werden intensivierte Nachsorgeprogramme angeboten. Bei Mutationen in bestimmten Risikogenen kommen risikoreduzierende Operationen in Betracht. Zudem ergeben sich therapeutische Implikationen, etwa der Einsatz von PARP-Inhibitoren bei BRCA1/2-assoziierten HER2-negativen Mammakarzinomen. Für Angehörige kommen prädiktive genetische Untersuchungen infrage sowie ggf. intensivierte Früherkennungsprogramme und risikoreduzierende Operationen.Die enge interdisziplinäre Zusammenarbeit ist entscheidend, um Patientinnen mit möglicher hereditärer Tumorgenese frühzeitig zu identifizieren und eine individualisierte Therapie- und Nachsorgestrategie zu ermöglichen.","42202251":"ID: 42202251\nTitle: Beyond Time Saved: Implementation, Equity, and the Utility Threshold for Nursing AI Scribes.\nAbstract: Schwabe et al's pre-post time-motion study of a domain-specific artificial intelligence (AI) speech assistant used by nurses in German long-term care provides one of the few real-world, full-shift evaluations of an AI scribe deployed to a nonphysician workforce, with paired objective observation and self-reported outcomes. This commentary points to the implications of these findings that extend well beyond the time savings headline. The study reports substantial reduction in self-reported documentation time and increased satisfaction with the documentation system, yet workplace satisfaction and the perception that AI scribes are \"a good idea to implement\" did not improve. Taken together, these findings show three undertheorized issues for AI scribe implementation in nursing and long-term care. First, postimplementation increases in time spent reviewing entries and retrieving information indicate that AI scribes redistribute cognitive effort from authoring to verification, with unknown consequences for satisfaction, mastery, and error detection. Second, the apparent paradox of rising documentation satisfaction alongside falling expectations of AI quality represents user calibration. Third, the substantial equity considerations of automatic speech recognition documentation reflect a broader trend of AI scribe studies that treat equity as a caveat, rather than treating equitable performance as empirically measurable and testable across variations in linguistic styles, dialects, and social linguistic dimensions. To advance the field, the next generation of nursing AI scribe research must treat documentation as a heterogeneous bundle of authoring, reviewing, retrieving, and verifying activities with distinct satisfaction and error profiles; specify and validate end-user-defined anchor utilities, rather than having a narrow focus on diffuse improvement; and treat equity testing and reporting of both automatic speech recognition systems and workforce adoption as standard reporting expectations, rather than caveats.","42204548":"ID: 42204548\nTitle: Putative glymphatic dysfunction links extracellular fluid dysregulation to white matter degeneration and clinical impairment in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron degeneration and prominent extra-motor involvement. Impaired clearance of neurotoxic proteins has led to increasing interest in the brain glymphatic system; however, its in vivo associations with brain microstructure and clinical heterogeneity remain incompletely understood. One hundred forty-six patients with ALS and 149 demographically matched healthy controls (HCs) underwent multimodal MRI and comprehensive clinical assessments. Putative glymphatic function was quantified using diffusion tensor imaging along perivascular space (DTI-ALPS). Extracellular free water fraction (FWF) and free-water-corrected fractional anisotropy (fwcFA) were derived to characterize extracellular fluid and white matter microstructure. Group differences were assessed using vertex-wise and voxel-wise analyses with correction for multiple comparisons. Associations among imaging metrics and clinical measures were evaluated using correlation and serial mediation analyses. Compared with HCs, patients with ALS exhibited significantly reduced DTI-ALPS index, widespread increases in cortical FWF, bidirectional alterations in white matter FWF, and extensive reductions in fwcFA across major white matter tracts. Reduced DTI-ALPS was associated with changes in extracellular free water and white matter microstructural integrity, whereas FWF and fwcFA measures were associated with functional, cognitive, and emotional outcomes. Mediation analyses identified significant indirect associations between DTI-ALPS and both functional and cognitive measures through a pathway involving cortical FWF, white matter FWF, and fwcFA, although direct associations were not observed. These findings provide in vivo evidence that putative glymphatic dysfunction co-occurs with extracellular fluid alterations, white matter microstructural changes, and clinical impairment in ALS. Multi-compartment diffusion imaging may offer complementary markers for characterizing brain microstructure and its clinical relevance in ALS.","42212970":"ID: 42212970\nTitle: DIGEST Grades Remain Stable With Inclusion of Moderately Thickened Liquids in the Videofluoroscopic Examination in Individuals With Amyotrophic Lateral Sclerosis.\nAbstract: The Dynamic Imaging Grade of Swallowing Toxicity (Version 2; DIGESTV2) is a videofluoroscopy (VF) scale that measures pharyngeal swallowing severity based on functional measures of swallowing safety and efficiency. Original validation is based on a standard VF testing protocol including thin liquid, puree, and solid consistencies. Given that thickened liquid bolus trials are common in VF clinical testing protocols, we sought to determine the agreement in DIGESTV2 grades with and without the inclusion of moderately thick liquid bolus trials on DIGESTV2 outcomes in people with amyotrophic lateral sclerosis (pALS). This study represents a secondary analysis of VF examinations from a prospective longitudinal study conducted in 109 pALS. VF evaluations contained 10 barium trials spanning three International Dysphagia Diet Standardisation Initiative (IDDSI) levels (0-7). Duplicate, independent, and blinded ratings were completed. DIGESTV2 Efficiency and Safety grading was then completed under two conditions-with and without the inclusion of moderately thick liquid bolus trials into DIGESTV2 grading-to produce two sets of DIGESTV2 ratings for each VF study. Descriptives, percent agreement, and a weighted Cohen's kappa were performed on DIGESTV2 grades. A total of 373 VF examinations were included in this analysis. DIGESTV2 grade percent agreement with and without IDDSI Level 3 was excellent for Safety (98.1%), Efficiency (93.8%), and Total (94.1%) grades. Kappa values for Safety, Efficiency, and Total grades were .96, .89, and .91, respectively, indicating excellent agreement across bolus trial inclusion methods. Standard inclusion of moderately thick liquid bolus trials did not significantly impact DIGESTV2 grading in this data set. These results add to the preliminary but growing evidence suggesting stability of DIGEST grading with alternate bolus protocols in another patient population. https://doi.org/10.23641/asha.32348451.","42214042":"ID: 42214042\nTitle: Diagnostic Revision From Primary Lateral Sclerosis to Amyotrophic Lateral Sclerosis: A Cohort Study.\nAbstract: Primary lateral sclerosis (PLS) is defined as a pure upper motor neuron syndrome and is a diagnosis of exclusion, amyotrophic lateral sclerosis (ALS) being the most likely alternative diagnostic consideration. A minimum disease duration of 2 years is required for the diagnosis of PLS, after which patients are classified as probable PLS (P-PLS) and subsequently as definite PLS (D-PLS) after 4 years. Our aim is to apply the current diagnostic criteria to a population-based cohort and investigate which clinical characteristics are associated with a diagnostic revision to ALS. This cohort study included patients meeting the current diagnostic criteria for PLS retrospectively from the Dutch Motor Neuron Disease Registry. Diagnostic revision to ALS was based on clinical assessment, EMG findings according to the revised El Escorial Criteria, or if patients had died from disease progression within 4 years of disease onset. Clinical characteristics were compared for patients who underwent diagnostic revision with ALS vs true PLS. Subdistribution hazard ratios (SHRs) for characteristics associated with diagnostic revision were determined using Fine-Gray regression. We included 478 patients (median age of onset 59.3 years, interquartile range 50.8-67.0, 47.9% female), of whom 311 (65.1%) met criteria for P-PLS and 167 (34.9%) for D-PLS at diagnosis. Eighty-eight patients (18%) underwent diagnostic revision to ALS, 76 cases (86%) before 4 years of disease duration. Patients whose diagnosis was revised to ALS had higher median age at onset (63.4 vs 58.0 years, p = 5.20 × 10-4), more often had bulbar onset (38.6% vs 19.7%, p = 6.19 × 10-4), and faster progression (median ALS Functional Rating Scale-revised slope 0.43 vs 0.18, p = 6.05 × 10-11). The risk of diagnostic revision increased if progression rate was faster (SHR 3.08 95% CI 1.69-5.60, p = 2.35 × 10-4) and if diagnosis was P-PLS compared with D-PLS (SHR 3.08, 95% CI 1.65-5.74, p = 3.96 × 10-4). In our cohort, most diagnostic revisions from PLS to ALS were in patients with a disease duration of less than 4 years. Besides disease duration, a faster progression rate was associated with diagnostic revision from PLS to ALS. Adding progression rate to the current diagnostic criteria could increase accuracy and help identify patients at higher risk of developing ALS.","42214970":"ID: 42214970\nTitle: The beat in speech: A window into the attentional mechanisms supporting the detection of non-adjacent dependencies.\nAbstract: Converging evidence suggests that musical training can elicit positive transfer effects across multiple domains of language processing, including grammar. In humans, exposure to musical rhythm induces beat and meter perception, which has been shown to enhance attentional allocation and temporal prediction. Theories hypothesize that the predictive gains intrinsic to music rhythmicity may exert cascading effects on syntactic processing by modulating sensitivity to speech prosody. From this perspective, learning should also be boosted insofar as prosody tends to align with grammatical structure. In the present study, we introduce a novel behavioural paradigm to investigate the link between rhythmicity and grammar learning by testing whether the rhythmic beat facilitates the detection of grammar-like structures in artificial languages (ALs), implemented as non-adjacent dependencies (NADs) between variable syllables forming a speech stream (e.g., PU reliably predicts KI in PUlaruKI). A total of 147 participants were exposed to four ALs that varied in rhythmic, grammatical structure, and the alignment between the two: (i) a beat-inducing rhythm with no NADs; (ii) a beat-hindering rhythm with NADs; (iii) a beat-inducing rhythm with embedded NADs temporally misaligned, and (iv) NADs aligned with beat time-points. Results of the implicit and, after exposure, explicit learning measures demonstrate enhanced learning when NADs are embedded within beat-inducing rhythmic structures. Together, these findings suggest that rhythm enhances predictive and attentional mechanisms implicated in grammar learning, underscoring their role in its acquisition.","42225765":"ID: 42225765\nTitle: Longitudinal cognitive assessment using the Cumulus NeuLogiq platform in amyotrophic lateral sclerosis and frontotemporal dementia.\nAbstract: People living with ALS (plwALS) and/or FTD (plwFTD) often experience cognitive and behavioural changes. However, detection can be confounded due to factors like fatigue and testing anxiety. Cumulus neuroscience developed NeuLogiq(R), a multi-modal neurocognitive platform that can be used in clinic or at home, providing an ecologically valid measure of cognition. This study examined the feasibility and usability of NeuLogiq in plwALS, plwFTD, and controls, and compared performance on gold standard neuropsychological assessments with corresponding NeuLogiq digital assessments. Over 8 months, plwALS (n = 11), plwFTD (n = 7), and matched healthy controls (n = 10) completed longitudinal full neuropsychological assessment, as well as three 25-minute NeuLogiq Platform sessions every 2 weeks in their homes. Participants adhered well to the study schedule, conducting over 32/54 sessions on average. All groups rated usability in the 'good' or 'excellent' range and had > 80% complete data. Baseline group differences were detectable on both NeuLogiq digital assessments and benchmark neuropsychological assessments of similar cognitive domains. Longitudinal mixed effects models found that the ALS group showed decline on NeuLogiq measures of emotion recognition and speech fluency. These findings suggest that the NeuLogiq platform is feasible and usable for plwALS and plwFTD, and can identify cognitive deficits to a similar extent as benchmark assessments over time.","42230395":"ID: 42230395\nTitle: [Media coverage of doping: subjective perceptions, evaluations, and perceived effects among elite athletes].\nAbstract: Media coverage of doping almost always focuses solely on athletes. But do they even read reports on doping? How do athletes evaluate doping coverage? And what impact can doping reports have on elite athletes? In 2025, a quantitative online survey was conducted among German national team athletes. Using descriptive and inferential statistics, 349 questionnaires were analyzed. Of the athletes, 85% read doping reports to learn how a doping case arises and how the media handles it. Of the respondents, 62% are pleased when doping offenders are caught and subsequently exposed through media coverage. Disappointment sets in for 60% because doping reports can damage the image of their own sport, and 38% of athletes expressed frustration with the media's tendency to almost exclusively criticize athletes but not other groups who share responsibility for doping. Approximately 15% of respondents believe doping reports can influence mental or physical performance, with some respondents suggesting increased training intensity and greater motivation in competition, while others suspect reduced training and demotivation in competition. The variables of age and gender do not play a role in the response patterns. The majority of athletes follow doping reports primarily out of a need for information and support the media's role in providing normative criticism and control. While doping reports are perceived as damaging to the image of their own sport, the media's educational efforts and the exposure of doping offenders are also seen as an important contribution to maintaining fair competition in sports.

Die Mehrheit der Athleten rezipiert die Dopingberichte aus einem Informationsbedürfnis heraus und viele Befragte befürworten die normative Kritik- und Kontrollfunktion der Medien. Dopingberichte werden zwar als imageschädigend für die eigene Sportart empfunden. Aber die Aufklärungsarbeit der Medien und die Demaskierung von Dopingsündern werden auch als ein wichtiger Beitrag zur Aufrechterhaltung eines fairen sportlichen Wettbewerbs gesehen.","42236740":"ID: 42236740\nTitle: HeyJay! A corpus of atypical speech for spoken language understanding and automatic speech recognition.\nAbstract: Speech technologies, such as automatic speech recognition or spoken language understanding, are not usually adapted to atypical speech, i.e., the speech of people with dysarthria, dysphonia, or another type of speech impairment. That prevents atypical speakers from leveraging speech assistants or other human-machine-interaction-powered platforms, which could make their lives easier or increase their independence. In this article, we present HeyJay!, a new corpus of atypical speech in English language from participants with neurodegenerative disorders, including Parkinson's Disease, or Amyotrophic Lateral Sclerosis. The current corpus version comprises 8,669 utterance recordings, including supervised transcriptions and intent annotations. In this study, we demonstrate the validity of the corpus by applying it to automatic speech recognition, spoken language understanding, and data augmentation tasks. Additionally, the dataset includes speech quality ratings for each participant, performed by expert speech and language pathologists. This corpus, the first one with intent annotation of atypical speech that is publicly available, is intended to create more fair speech technologies for atypical speakers by adapting and improving the state of the art, and to facilitate further research in the field.","42237658":"ID: 42237658\nTitle: Neuroprotective Effects of RNS60 in TDP-43 Pathology-Associated Amyotrophic Lateral Sclerosis.\nAbstract: TDP-43 pathology is broadly observed in the cerebral cortex of patients with amyotrophic lateral sclerosis (ALS). RNS60, an experimental treatment for acute ischemic stroke and ALS, enhanced mitochondrial biogenesis and function in other preclinical models. We investigated whether RNS60 improved mitochondrial stability and upper motor neuron (UMN) health in a TDP-43 mouse model of ALS. prpTDP-43A315T-UeGFP mice, in which UMNs express green fluorescent protein (eGFP), and WT-UeGFP mice were treated with RNS60 or placebo intraperitoneally every other day from post-natal day (P) 30 until P90. Astrogliosis and microgliosis in brain and spinal cord were quantified by immunocytochemistry. Mitochondrial ultrastructure was studied via electron microscopy, and mitochondrial function was assessed using flow cytometry. Neuromuscular junction (NMJ) integrity was assessed in gastrocnemius, tibialis, and diaphragm muscles. RNS60 treatment reduced defective mitochondria in UMNs (prpTDP-43A315T + vehicle: 53.2% ± 0.71%; prpTDP-43A315T + RNS60: 19.6% ± 1.4%, p = 0.0001) and spinal motor neurons (prpTDP-43A315T + vehicle: 70.1% ± 0.4.48%; prpTDP-43A315T + RNS60: 33.5% ± 4.43%, p = 0.001). It increased mitochondrial membrane polarization (prpTDP-43A315T-UeGFP + vehicle: 7184 ± 1689 mean intensity; prpTDP-43A315T-UeGFP+RNS60: 22120 ± 4818 mean intensity, p = 0.032), reduced the extent of astrogliosis and microgliosis in motor cortex and spinal cord, protected UMNs compared to placebo, and enhanced the proportion of intact NMJs in leg and diaphragm muscles (prpTDP-43A315T-UeGFP + vehicle: 29.6% ± 3.6%; prpTDP-43A315T-UeGFP + RNS60: 64.3% ± 4.4%, p = 0.0002). These results suggest that RNS60 treatment promotes motor neuron health in ALS by protecting mitochondrial structure and function, preserving NMJ integrity, and reducing gliosis.","42241188":"ID: 42241188\nTitle: The Unfinished Breath: Caregiver Perceptions of Terminal Events and Gaps in Amyotrophic Lateral Sclerosis Care in India.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with a high symptom burden and limited survival. Little is known about the terminal phase experiences, symptom prevalence, and end-of-life care patterns of people with ALS (PALS) in India. This study aimed to assess terminal events and caregiver-reported outcomes in PALS to identify gaps in ALS care delivery in India. A cross-sectional telephonic survey was conducted among bereaved caregivers of PALS enrolled in the Neuropalliative and Supportive Care project between December 2021 and May 2024. A structured, validated questionnaire was used to collect data on demographics, terminal-phase symptoms, medical interventions, and the nature of death as perceived by primary caregivers. Descriptive statistics and appropriate statistical analyses were performed. A total of 130 caregivers participated in the survey; the majority (57.7%) were sons or daughters. Among the 130 PALS, 76 (58.5%) were men; 56.2% had limb onset and 43.8% had bulbar onset. The mean age at death was 53.5 ± 11.4 years. Most patients (57.7%) died at home, and 29.2% experienced sudden death. Patients who died in the hospital were more likely to be on invasive mechanical ventilation ( P < 0.001). The most common terminal symptoms were breathlessness (79.2%), excessive oral secretions (54.6%), followed by anxiety or restlessness (44.6%). Only 20% received bilevel positive airway pressure, and 25.4% were on percutaneous endoscopic gastrostomy. A significant association was found between bulbar onset and assisted feeding ( P = 0.002). This study highlights the need for proactive, community-integrated palliative care services and emphasizes the urgency of early intervention and caregiver support to improve end-of-life experiences in PALS in India.","42251620":"ID: 42251620\nTitle: Tongue volume in spinal and bulbar muscular atrophy (SBMA): an AI-assisted automatic MRI analysis.\nAbstract: Atrophy of the tongue muscle without severe dysarthria is one of the clinical hallmarks of spinal and bulbar muscular atrophy (SBMA), a motor neuron disease caused by an androgene receptor defect. An operator-independent AI-based automatic segmentation of the tongue was applied to 3-D MRI data of the head in SBMA in order to quantify the tongue atrophy. Thirty-nine patients with SBMA and 51 age-matched healthy controls underwent MRI which were used for tongue volume quantification. A single triplanar convolutional neural network of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head, the resulting volumes were processed slice-wise across the three orientations and corrected for age. At the group level, a significant atrophy of the tongue was observed in SBMA when compared to controls (p < 0.05). Atrophy correlated well with total SBMA-functional rating scale and even more with bulbar subscores. In summary, the study employed an AI-assisted advanced imaging analysis to quantify the tongue morphology in individuals with SBMA in correlation to clinical bulbar function, suggesting this approach as a potential biomarker for disease assessment.","42259250":"ID: 42259250\nTitle: A note of caution on tone language advantages for music.\nAbstract: Liu et al.1 reported recently in Current Biology a large-scale citizen science replication of the tone-language advantage for musical pitch perception. Their 493,100 volunteers spoke 54 languages, including 19 tone languages, those in which a word's pitch pattern contributes to its meaning. For example, Mandarin ma with high pitch means 'mother', while ma with dipping pitch means 'horse'. Previous studies reported tone language advantages, but with far smaller and less linguistically diverse samples (mostly East Asian tone languages). I applaud the authors' exploration of diverse tone languages with disparate tonal properties, including varying numbers, types, and linguistic uses of tones, plus varying cultural factors. While I do not dispute the overall tone language advantage, I take issue with Liu et al.'s1 inference that the effect is consistent across the varied tone languages tested: because of the properties of the models they used to estimate individual-language effects, their more-diverse tone languages spuriously appear to pattern consistently, when in actuality the data are too noisy to draw strong conclusions about tone languages as a unified group.","42262640":"ID: 42262640\nTitle: Sensory Reactivity in Autism: Integrating Behavioural, Affective, Physiological, and Neural Dimensions.\nAbstract: The goal of this paper is to synthesise recent research on sensory reactivity differences in autism across the lifespan, using He et al.'s sensory taxonomy as an organising framework. The review aims to address how behavioural, affective, perceptual, physiological, and neural levels of processing contribute to sensory reactivity differences, and how these differences relate to broader outcomes such as mental health, adaptive functioning, and quality of life. Across behavioural studies, autistic youth show elevated and variable sensory responsivity, with hypersensitivity predicting internalising symptoms and sensory seeking linked to externalising behaviours. Affective reactivity is consistently elevated across cultures, associated with anxiety and caregiver stress, and sensory seeking may function as a coping mechanism. Psychophysical research reveals domain‑specific perceptual differences-such as reduced tactile adaptation, altered motion noise exclusion, and enhanced pitch discrimination-rather than overarching hyper‑ or hyposensitivity. These perceptual findings often show limited correspondence with questionnaire‑based measures. Physiologically, autonomic dysregulation is implicated, or pharmacological approaches show emerging promise. Neuroimaging evidence highlights excitation-inhibition imbalance and altered connectivity, including dissociations between exogenous and endogenous networks in sensory‑reactive autistic children. Across multiple levels of processing, sensory reactivity differences in autism are robust, heterogeneous, and meaningfully linked to mental health and daily functioning. Key conclusions include: • Sensory hyperreactivity predicts internalising challenges, while sensory seeking may reflect regulatory strategies. • Perceptual differences are domain‑specific • Physiological and neural evidence converges on autonomic dysregulation and differences in connectivity patterns.","42263370":"ID: 42263370\nTitle: Sensory abnormalities and entrapment neuropathies identified by nerve conduction studies in patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder primarily affecting motor neurons; however, non-motor symptoms, including sensory and autonomic disturbances, are increasingly recognized. This retrospective cross-sectional study evaluated the frequency of sensory and entrapment neuropathies in 114 patients with ALS using electrodiagnostic (EDX) studies. Demographic characteristics, comorbidities, and sensory and autonomic symptoms were documented. Electrophysiological evidence of sensory neuropathy was identified in 20 patients overall (20/114, 17.5%), including 10 patients without diabetes mellitus (DM), whereas entrapment neuropathy was detected in 28 patients overall (28/114, 24.6%), including 16 of those without DM or hypothyroidism. Sensory neuropathy was significantly associated with both DM and a history of chronic disease. In contrast, these comorbid conditions were not significantly associated with entrapment neuropathy. Furthermore, patient-reported symptoms showed no correlation with electrophysiological evidence of sensory involvement on EDX. Sensory neuropathy was more frequent in patients with spinal-onset than bulbar-onset disease, although the difference was not statistically significant. This study confirms that sensory involvement is not uncommon in ALS. Although clinical symptoms are poor predictors, electrophysiological abnormalities consistent with sensory and entrapment neuropathies are common. A significant proportion of these abnormalities are idiopathic and may directly reflect the disease process itself, particularly in spinal-onset cases.","42263783":"ID: 42263783\nTitle: Association of Brief Bouts of Vigorous Physical Activity and Frailty in Older Adults With Regular and Irregular Exercise Habits.\nAbstract: Brief bouts of vigorous physical activity such as vigorous intermittent lifestyle physical activity (VILPA) have emerged as a flexible alternative to traditional structured exercise, requiring less time commitment, preparation, and access to facilities. This study explored the association between VILPA and the odds of prefrailty or frailty in 195 older adults aged 65 and above at National Taiwan University Hospital. Frailty status was evaluated using Fried et al.'s criteria, which include slowness, weakness, weight loss, exhaustion, and low physical activity. VILPA was measured using a waist-worn accelerometer. Multivariate binary logistic regression models revealed that meeting the VILPA duration or bouts thresholds was linked to lower odds of prefrailty or frailty. These associations were significant in those with irregular exercise habits, with adherence to VILPA duration or bouts thresholds correlating with reduced prefrailty or frailty likelihood (odds ratio = 0.21, 95% confidence interval [0.05, 0.89]). However, no significant associations were observed in individuals with regular exercise habits. Adhering to VILPA thresholds may be associated with lower frailty odds, particularly in older adults with irregular exercise habits. These findings suggest that promoting brief bouts of vigorous physical activity in daily life may have potential implications for frailty reduction in older adults, especially those who do not engage in regular exercise. This approach offers a potentially accessible and flexible alternative to structured exercise programs for maintaining health in aging populations.","42268433":"ID: 42268433\nTitle: FUS-associated ALS in Taiwan: genetic spectrum, clinical features, and a founder haplotype of p.H517D.\nAbstract: To characterize the genetic spectrum and clinical features of FUS-associated amyotrophic lateral sclerosis (ALS) in a Taiwanese cohort and to investigate whether the recurrent p.H517D variant represents a founder mutation. All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6 years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.","42269975":"ID: 42269975\nTitle: Progressive choroid plexus enlargement across disease stages in patients with sporadic amyotrophic lateral sclerosis.\nAbstract: The choroid plexus (CP), a key structure involved in cerebrospinal fluid homeostasis and glymphatic function, is increasingly recognized as an interface for neuroimmune communication. Recent studies have identified CP abnormalities as potential neuroimaging markers in several neurodegenerative disorders, including sporadic amyotrophic lateral sclerosis (sALS). However, whether CP enlargement occurs early and progresses across clinical stages or over time in patients with sALS remains unclear. Given the role of the CP in peripheral-central nervous system immune crosstalk, the association between neuroinflammation and CP abnormalities in sALS also requires clarification. In this prospective study, we used structural MRI to examine cross-sectional and longitudinal CP volume changes in patients with sALS and to evaluate their associations with CSF inflammatory markers. This prospective study included 161 newly diagnosed patients with sALS who underwent genetic testing and structural MRI, and 64 healthy controls (HCs) who underwent structural MRI. Disease stage in patients with sALS was assessed using the King's staging system. Longitudinal MRI was performed in a subset of 42 patients, of whom 38 also underwent baseline CSF inflammatory protein assessment. Compared with HCs, patients with sALS at all King's stages showed significantly larger CP volumes after Bonferroni correction (all p < 0.05). CP volumes were significantly greater in patients at King's stage 3 than in those at King's stage 1 or stage 2 after Bonferroni correction (all p < 0.05). In the longitudinal subgroup, CP volume increased significantly from baseline to follow-up. Multivariable analysis showed that higher CSF CHIT1 and IL-6 levels were independently associated with larger CP volume in patients with sALS (β = 0.348-0.456; p < 0.01). Our findings provide evidence that CP enlargement occurs early and progresses across disease stages and over time in patients with sALS. Higher CSF CHIT1 and IL-6 levels were associated with larger CP volume, supporting a potential link between neuroinflammation and CP abnormalities in sALS. These findings support CP enlargement as a promising neuroimaging marker for monitoring disease progression and neuroinflammatory processes in patients with sALS.","42272365":"ID: 42272365\nTitle: Incidental Radiation Exposure to the Internal Mammary Lymph Nodes in Breast Cancer Patients Undergoing Intensity-Modulated Radiation Therapy: A Retrospective Analysis.\nAbstract: Breast cancer (BC) remains the most common malignancy among Indian women, with Stage III being the most frequent at diagnosis. While radiation therapy (RT) plays a pivotal role in the adjuvant treatment of breast cancer, the inclusion of internal mammary lymph nodes (IMLNs) in the radiation field remains controversial due to potential cardiopulmonary toxicity. However, the extent of incidental radiation to the IMLNs, especially with forward planning intensity-modulated radiation therapy (IMRT), remains under-explored. This study aimed to evaluate the incidental radiation dose received by the IMLNs in patients with leftsided breast cancer treated with forward planning IMRT. A total of 36 left-sided breast cancer patients, aged 35-60 years, who underwent modified radical mastectomy followed by adjuvant RT using IMRT, were retrospectively analyzed. CT-based planning and contouring were performed according to RTOG guidelines, with IMLNs contoured retrospectively using Jetwa et al.'s method. Dosimetric parameters for the planning target volume (PTV) and IMLNs were extracted and analyzed using dose-volume histograms. Statistical comparisons were made using the dependent Student's t-test. The PTV received effective radiation coverage with a mean D95 of 38.47 Gy and a mean Dmean of 40.10 Gy. The IMLNs, although not directly targeted, received significant incidental radiation, with a mean D95 of 8.49 Gy, D50 of 21.59 Gy, and Dmean of 21.40 Gy. The maximum dose to the IMLNs (Dmax) reached 38.14 Gy. Comparative analysis revealed statistically significant differences in both Dmax and Dmean between PTV and IMLNs (p = 0.004 and p < 0.001, respectively). Forward planning IMRT provides substantial incidental radiation exposure to the IMLNs, which may have therapeutic implications in reducing recurrence risk. However, this exposure also necessitates careful consideration of potential long-term toxicities to adjacent organs. Further prospective studies are warranted to evaluate the clinical outcomes associated with incidental IMLN irradiation.","42273832":"ID: 42273832\nTitle: Remote, self-administered, smartphone cognitive testing in a registry-based cohort: Feasibility, reliability, and validity findings.\nAbstract: Remote, smartphone-based cognitive testing may improve access to cognitive assessments for Alzheimer's disease and related dementias. We evaluated the feasibility, reliability, and validity of unsupervised smartphone-based cognitive tests in a registry-based cohort. Adults without a record of cognitive impairment (N = 1815; ages 18-92) were recruited from the University of California, San Francisco (UCSF) Brain Health Registry to complete three unsupervised smartphone cognitive testing sessions within 2 weeks. Reliability was assessed with correlations between sessions. Linear regression models tested associations of smartphone tasks with demographics, self- and informant-rated cognitive concerns, and web-based cognitive testing (Cogstate Brief Battery). Adherence was high (82.2%) and usability favorable. Test-retest reliability was moderate to strong (ρ's = 0.61-0.85, all p's < 0.001). Lower smartphone scores were associated with older age, lower education, cognitive concerns, and worse Cogstate performance. Findings support the feasibility, reliability, and validity of remote digital assessments in adults without a record of cognitive impairment.","42276630":"ID: 42276630\nTitle: Accreditation as opportunity: Preparing future nursing leaders through faculty collaboration and succession planning.\nAbstract: Preparing for Commission on Collegiate Nursing Education (CCNE) accreditation requires extensive faculty engagement, yet the literature offers limited guidance on operational strategies to cultivate collaboration and mentorship during this process. This article describes the Keigwin School of Nursing's adaptation of Benner's novice to expert framework and Haverkamp et al.'s (2018) \"map for accreditation\" to design a collaborative approach for developing the self-study report and preparing for a site visit. Junior faculty were paired with experienced mentors in dyads, assigned to analyze key elements of the CCNE Standards, and reported findings back to cross-program Standard Teams. This structure fostered faculty development, enhanced understanding of accreditation processes, and promoted succession planning. Standardized meeting minutes, end-of-year committee reports, and the use of stoplight tracking tools provided systematic evidence of continuous quality improvement. Faculty-wide meetings and individualized support further strengthened readiness and confidence for site visit engagement. The outcome was full faculty participation, successful alignment of undergraduate and graduate program reaccreditation cycles, and no accreditation compliance concerns reported for any program. These results underscore the value of mentorship, collaboration, and succession planning in accreditation preparation and highlight the potential to address national challenges in faculty shortages, destabilization of higher education, and the need for a unified nursing faculty voice in academic advocacy.","42283699":"ID: 42283699\nTitle: Supporting gastrostomy decision-making in motor neurone disease (MND): an Australian survey of healthcare professionals' beliefs, practices, and needs.\nAbstract: Gastrostomy decision-making for people living with motor neurone disease (MND) is complex. While international studies report healthcare professionals' (HCPs) beliefs and practices in this area, little is known about the Australian context. To examine Australian HCPs' beliefs, clinical practices, and support needs regarding gastrostomy decision-making in MND. A national cross-sectional online survey of Australian HCPs involved in gastrostomy discussions (n = 123) was conducted, exploring five domains: 1) initiating discussions and timing; 2) patient education; 3) multidisciplinary coordination; 4) guideline use; 5) and professional development needs. Descriptive statistics were applied. Most HCPs initiated discussions about gastrostomy (74%), commonly prompted by swallowing difficulty, weight loss, or patient request. Although 72% believed discussions should occur before clinical indications, only 40% reported doing so. Earlier placement was favored in the context of respiratory decline compared with swallowing impairment, and 56% considered gastrostomy to be performed too late. Almost 40% used no formal guidelines, and 74% wanted further professional development. Australian HCPs valued person-centered practice, but belief-practice gaps highlight opportunities to improve consistency, timing, and quality of gastrostomy decision-making support. Enhanced national guidelines, improved multidisciplinary communication, and targeted professional development may help reduce delays and better align practice with evidence-based recommendations. People living with motor neurone disease (MND) often have trouble swallowing. They may lose weight and find it hard to take medications. A feeding tube (gastrostomy) can help with food, fluids, and medication. However, deciding if and when to have a feeding tube can be difficult and emotional for people with MND and their families.Healthcare professionals play an important role in giving information and supporting these decisions. However, we do not know much about how healthcare professionals in Australia manage these discussions.In this study, we surveyed 123 Australian healthcare professionals from different fields who work with people with MND. We asked when they talk about feeding tubes, what information they give, how they work with other team members, what guidelines they use, and what training they need.Most healthcare professionals said they talk about feeding tubes when swallowing problems or weight loss begin, or when patients ask about it. Many said these conversations should happen earlier, but fewer said they actually do this. They often talked about nutrition and daily life with a feeding tube. They were less likely to talk about prognosis or the risks of waiting too long.Some healthcare professionals said communication within the care team can be difficult. Many do not use formal guidelines. Most said they would like more training, especially in decision-making and having difficult conversations.These results show ways to improve care in Australia. This includes clearer guidelines, better team communication, and more training for healthcare professionals.","42285406":"ID: 42285406\nTitle: Recent advances in neurodegenerative diseases therapeutics: The inhibition of monoacylglycerol lipase strategy.\nAbstract: Neurodegenerative diseases share common pathophysiological mechanisms, including chronic neuroinflammation, glutamatergic excitotoxicity, oxidative stress, mitochondrial dysfunction, and disruptions in synaptic and lipid homeostasis. In this context, the endocannabinoid system has emerged as a key modulator of neuroimmune communication and neuronal survival. Within this system, Monoacylglycerol Lipase (MAGL) plays a central role by regulating the levels of the endocannabinoid 2-Arachidonoylglycerol (2-AG) while simultaneously contributing to the generation of arachidonic acid and pro-inflammatory eicosanoids. Pharmacological or genetic inhibition of MAGL increases 2-AG levels and concurrently reduces the biosynthesis of pro-inflammatory lipid mediators, thereby modulating microglial activation, astrocytic responses, and neuronal excitotoxicity. Preclinical studies in models of Alzheimer's disease, Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis consistently demonstrate that MAGL blockade attenuates neuroinflammation, preserves synaptic and neuronal integrity, improves motor and cognitive function, and, in some cases, delays disease progression. Although clinical evidence remains limited, the available data position MAGL as a metabolic convergence point between inflammation and neurodegeneration, suggesting that its modulation may represent a therapeutic strategy with disease-modifying potential.","42290559":"ID: 42290559\nTitle: Integrated Analysis of hsa-miR-26b-5p and hsa-miR-186-5p in Blood Serum and Tumor Tissue Reveals their Prognostic and Predictive Significance in Breast Cancer.\nAbstract: Breast cancer (BC) heterogeneity signifi antly complicates diagnosis, prognosis, and prediction of treatment response. MicroRNAs (miRNAs) have emerged as promising biomarkers due to their involvement in tu- mor progression and in regulating therapy sensitivity. however, the combined clinical signifi ance of circulating and tumor-associated miRNAs, such as hsa-miR-26b-5p and hsa-miR-186-5p, remains insuffi    tly elucidated. Materi- als and Methods. Expression levels of hsa-miR-26b-5p and hsa-miR-186-5p were analyzed in serum and tumor tis- sue of 124 BC patients. Associations with clinicopathological parameters were assessed. The prognostic signifi ance was evaluated based on disease progression and recurrence within 3 years. The predictive value was determined in patients receiving neoadjuvant chemotherapy (4AC regimen) using response assessment and ROC analysis. Re- sults. young BC patients (≤45 years) demonstrated signifi antly lower circulating levels of both miRNAs. Serum hsa-miR-186-5p expression was associated with early-stage disease, tumor size, lymph node status, and molecular subtype. Increased circulating hsa-miR-26b-5p levels were linked to disease progression, whereas decreased hsa- miR-186-5p levels were observed in patients with unfavorable outcomes. In tumor tissue, hsa-miR-26b-5p expres- sion correlated with tumor grade, size, and metastatic status, showing elevated levels in poorly differentiated tumors and reduced expression in metastatic disease. In contrast, hsa-miR-186-5p was associated with the molecular sub- type and lymph node involvement, with the highest expression observed in hER2-positive tumors and in patients with recurrence. Elevated levels of hsa-miR-186-5p in both serum and tumor tissue were associated with reduced sensitivity to doxorubicin-based neoadjuvant chemotherapy. ROC analysis confi med its predictive value (AUC =  0.750 for serum and 0.818 for tumor tissue). No signifi ant association between hsa-miR-26b-5p and chemothe- rapy response was observed. hsa-miR-26b-5p and hsa-miR-186-5p demonstrate complementary roles in BC biology. hsa-miR-26b-5p is primarily associated with tumor aggressiveness and cancer progression, whereas hsa-miR-186-5p refl cts its molecular characteristics and response to chemotherapy. Their combined assessment in serum and tumor tissue represents a promising approach for improving prognostic stratifi ation and predicting treatment effi acy in BC patients.","42293321":"ID: 42293321\nTitle: Quantitative susceptibility mapping reveals widespread brain iron abnormalities in sporadic patients with early-stage amyotrophic lateral sclerosis.\nAbstract: In the present study, using the novel quantitative susceptibility mapping technique, we aimed to systematically investigate brain iron alterations in a large group of sporadic early-stage amyotrophic lateral sclerosis patients and their correlation with clinical disability. In this study, amyotrophic lateral sclerosis patients at King's stage 1 were defined as early-stage amyotrophic lateral sclerosis patients, and 53 newly diagnosed early-stage amyotrophic lateral sclerosis patients and 50 healthy controls were included. Voxel-based whole-brain quantitative susceptibility mapping analysis was used to explore brain iron alterations. Voxel-based morphometry analysis was also performed. Longitudinal follow-up was performed in amyotrophic lateral sclerosis patients, and the follow-up progression rate was calculated. We found that, compared with healthy controls, early-stage amyotrophic lateral sclerosis patients presented significantly increased susceptibility values, mainly in the motor cortex, prefrontal cortex, hippocampus and cerebellar regions, while volumetric alterations were not detected. Moreover, motor and extra-motor cortex susceptibility values were significantly correlated with upper motor neuron scores and follow-up progression rate (r = 0.452-0.504, P < 0.01) in early-stage amyotrophic lateral sclerosis patients. We demonstrated a clear profile of early motor and extra-motor iron depositions and their important roles in early-stage amyotrophic lateral sclerosis patients. We suggest that quantitative susceptibility mapping is likely a promising neuroimaging approach for assessing early upper motor neuron damage and detecting early extra-motor alterations in amyotrophic lateral sclerosis patients.","42296263":"ID: 42296263\nTitle: Whole-body muscle MRI improves diagnostic certainty in amyotrophic lateral sclerosis.\nAbstract: Introduction: Early diagnosis of amyotrophic lateral sclerosis (ALS) remains challenging due to the absence of a definitive biomarker and the difficulty of demonstrating widespread lower motor neuron (LMN) involvement. Whole-body muscle MRI (WB-MRI) enables comprehensive assessment of muscle involvement and may improve detection of LMN dysfunction. This study aimed to evaluate whether WB-MRI improves diagnostic certainty in ALS when combined with clinical and electromyography (EMG) assessment. Methods: In this prospective single-center study, 47 patients with ALS underwent clinical examination, EMG, and WB-MRI. Diagnostic classification according to the Awaji criteria was assessed using clinical and EMG data alone and after integration of MRI markers of LMN involvement, including fatty infiltration and muscle edema, or muscle edema alone as a surrogate marker. Results: WB-MRI identified additional LMN-involved regions in 27.7% of patients when both fatty infiltration and muscle edema were considered, and in 42.6% when considering muscle edema alone. This resulted in diagnostic upgrading in 14.9% and 25.5% of patients, respectively. The proportion of definite ALS increased from 8.5% to 17.0% when muscle edema alone was considered. MRI had limited impact on diagnostic classification according to the Gold Coast criteria. Among patients without LMN involvement on clinical and EMG assessment (all with bulbar-onset), 50% were reclassified after MRI. Conclusion: WB-MRI improves detection of LMN involvement and increases diagnostic certainty according to the Awaji criteria, with muscle edema appearing to be the most relevant MRI marker for integration into ALS diagnostic assessment.","42297978":"ID: 42297978\nTitle: Long-term independent use of an intracortical brain-computer interface for speech and cursor control.\nAbstract: Brain-computer interfaces (BCIs) can provide naturalistic communication and digital access to people with severe paralysis by decoding neural activity associated with attempted speech and movement. Recent work has demonstrated highly accurate intracortical BCIs for speech and cursor control, but two critical capabilities needed for practical viability were unmet: independent at-home operation without researcher assistance and reliable long-term performance supporting accurate speech and cursor decoding. Here we demonstrate the independent and near-daily use of a multimodal BCI with novel brain-to-text speech and computer cursor decoders by a man with paralysis and severe dysarthria due to amyotrophic lateral sclerosis. Over nearly 2 years, the participant used the BCI for more than 3,800 h at home with no researchers present to maintain rich interpersonal communication with his family and friends, independently control his personal computer and sustain full-time employment-despite being paralyzed. He communicated 183,060 sentences-totaling 1,960,163 words-at an average rate of 56 words per minute. He labeled 92% of sentences as being decoded at least mostly correctly. In formal quantifications of performance where he was asked to say words presented on a screen, attempted speech was consistently decoded with more than 99% word accuracy (125,000 word vocabulary). The participant also used the speech BCI as keyboard input and the cursor BCI as mouse input to control his personal computer, enabling him to send text messages and emails and to browse the internet. These results demonstrate that intracortical BCIs have the potential to support independent use in the home, marking a critical step toward practical assistive technology for people with severe motor impairment.","42298083":"ID: 42298083\nTitle: The lung-brain axis in neurodegeneration: inflammatory, immune, and vascular mechanisms with therapeutic implications.\nAbstract: Neurodegenerative and chronic pulmonary diseases represent major global health challenges and have widely been investigated separately. Emerging evidence indicates the existence of a lung-brain axis, through which pulmonary pathology and environmental exposures can influence neurological health. The current review highlights the mechanistic and clinical evidence linking chronic lung inflammation, air pollution, and immune dysregulation to the onset and progression of Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS). A pathway-based framework is presented in which lung inflammation, systemic cytokine release, oxidative stress, blood-brain barrier disruption, immune priming, and protein misfolding mediate lung-to-brain communication. Associations between chronic obstructive pulmonary disease, asthma, particulate matter exposure, and adverse neurological outcomes including cognitive decline, brain atrophy, disease progression, and elevated neurodegenerative risk are emphasized. Specific mechanisms are addressed, including immune-mediated effects in multiple sclerosis, inhalation-driven protein aggregation in Parkinson's disease, and vascular and oxidative injury contributing to dementia and amyotrophic lateral sclerosis. COVID-19 is considered a clinical model of acute lung-brain axis disruption, demonstrating inflammation-driven neurocognitive consequences, and its role in this context was also highlighted. Additionally, potential preventive and therapeutic strategies are discussed, highlighting pulmonary health and environmental exposure reduction as modifiable factors that may help mitigate neurological disease. This integrative review underscores the clinical relevance of the lung-brain axis and calls for interdisciplinary strategies to improve neurological outcomes through pulmonary and environmental interventions.","42307135":"ID: 42307135\nTitle: Brain activity in an end-stage ALS patient suggests the presence of an unresponsive wakefulness syndrome.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease primarily affecting motor neurons. It is widely assumed that cortical structures beyond motor neurons are relatively preserved, and patients in the end-stage ALS are regarded as being in complete locked-in syndrome (cLIS). However, emerging evidence suggests substantial heterogeneity in cognitive functioning among ALS patients, indicating possible extra-motor cortical involvement and impaired levels of consciousness. We report a case study assessing electrophysiological markers and auditory system integrity to evaluate the presence of covert consciousness in end-stage ALS. The patient was a 42-year-old woman with bulbar-onset, end-stage ALS, a six-year disease duration, and no means of communication. She underwent several EEG-based protocols, including resting-state EEG (RS-EEG), a passive auditory oddball paradigm, and 40 Hz auditory steady-state responses (ASSR). Audiological evaluation comprised transient-evoked and distortion-product otoacoustic emissions, as well as auditory brainstem responses (ABR). RS-EEG was dominated by prefrontal 1-3 Hz activity resembling frontal intermittent rhythmic delta activity. Power spectra were poorly differentiated and consistent with a 1/f profile. No event-related potentials were observed in the oddball paradigm, and no ASSR responses were detected. Audiological testing revealed absent otoacoustic emissions and ABR indicating severe to profound hearing loss. Our findings indicate severe cortical dysfunction and provide no electrophysiological evidence of covert consciousness. The electrophysiological profile closely resembles that observed in unresponsive wakefulness syndrome. This case supports the hypothesis that advanced ALS following cLIS onset may be more appropriately conceptualized as a disorder of consciousness rather than persistent cLIS.","42310079":"ID: 42310079\nTitle: Effect of subsequent passages on biofilm formation intensity, ALS genes expression, and cell surface hydrophobicity variability in clinical Candida albicans isolates.\nAbstract: Candida albicans is an opportunistic yeast pathogen that have several virulence factors included biofilm formation, cell surface hydrophobicity (CSH), and the expression of adhesion genes. Concerns exist that serial laboratory subculturing may diminish these traits, leading to inaccurate research findings. Aim of this study was evaluated the effect of subsequently subcultures on biofilm formation intensity, ALS gene expression, and surface hydrophobicity properties in clinical C. albicans isolates. Ten clinical C. albicans isolates were serially subcultured up to 20 passages (P). We used qPCR to quantify ALS1 and ALS3 gene expression, the Crystal Violet assay to measure biofilm formation intensity (P1, P5, P10, P15, P20), and a water-octane partitioning assay for CSH variability at different passages. Serial subculturing caused gradual downregulation of gene expression for both ALS1 and ALS3 (p < 0.001). This condition was accompanied by a biofilm-forming capacity that became progressively reduced in 90% of isolates, whereas 60% at P20 were already biofilm-negative (vs. 10% at P1). Cell surface hydrophobicity also decreased progressively, with 100% of isolates displaying low CSH at P15, compared with 40% in the initial P1 state. Serial subculturing leads to a rapid reduction of C. albicans pathogenic fitness with decreased expression of certain key adhesion genes, diminished biofilm formation, and lower CSH. These results highlight the plasticity of the organism and thus strongly suggest that low-passage clinical isolates should be used in studies to reflect true pathogenicity in vivo accurately.","42310450":"ID: 42310450\nTitle: A mosaic of whole-body representations on the human precentral gyrus.\nAbstract: Understanding how the body is represented in the motor cortex is key to understanding how the brain controls movement. Although the motor cortex has been mapped in animal models at a fine scale1-10, characterization in humans remains primarily limited to low-resolution recording11-16 and stimulation techniques17-20. Here we created a comprehensive map of the human motor cortex at single-neuron resolution, spanning microelectrode array recordings from 20 arrays across 8 individuals with paralysis from spinal cord injury, amyotrophic lateral sclerosis or brainstem stroke, all enrolled in brain-computer interface clinical trials. These arrays broadly sample the crown of the precentral gyrus (PCG; thought to be composed largely of the premotor cortex (Brodmann area 6)). We found that body parts were highly intermixed, such that the entire body was represented in all sampled locations of the PCG, although the relative strength of body parts was roughly consistent with the motor homunculus17,18. We also found two speech-preferential areas with a broadly tuned, orofacial-dominant area in between them. Throughout the PCG, movement representations of the four limbs were interlinked, with homologous movements of different limbs (for example, toe curl and hand close) having correlated representations. These data provide evidence consistent with an intermixed, interrelated and behaviour-centred organization of the motor cortex3,21. The resulting map also provides important targeting information for brain-computer interfaces that seek to restore motor function.","42313873":"ID: 42313873\nTitle: COVID-19 alert level systems-Lessons learnt for future public health emergencies: A qualitative study.\nAbstract: During the COVID-19 pandemic, Alert Level Systems (ALS) were widely implemented as public health tools to communicate risk levels and recommend public health and social measures (PHSMs). However, the efficacy of ALS in mitigating disease spread and their impact on public health responses have not been systematically evaluated. This study aims to assess perceptions of ALS implementation across diverse jurisdictions and derive lessons for future public health emergencies. Key informant interviews were conducted remotely between December 2023 and March 2024 with senior stakeholders who were involved in ALS development and implementation during the COVID-19 pandemic, from eight jurisdictions: California (US), New Zealand, the Philippines, Rio Grande do Sul (Brazil), Singapore, South Africa, the United Kingdom, and the United States. A thematic analysis approach was applied to synthesize insights, focusing on the strengths, challenges, and key lessons from ALS implementation. ALS were generally perceived by key informants as useful tools for communicating risk and supporting adherence to PHSMs due to their simplicity and transparency. However, significant challenges were identified, including difficulties in accessing reliable data, lack of clear ALS objectives, and insufficient community engagement. The study highlights the need for ALS to integrate social, economic, and epidemiological data in decision-making processes. Jurisdictions also reported that pre-existing ALS governance structures and stronger community feedback mechanisms could have improved implementation outcomes. ALS can serve as valuable public health communication tools in future epidemics, but their success depends on clear objectives, evidence-based PHSMs, and robust community engagement. Pre-emptive development of ALS structures and governance will improve preparedness for future epidemics. Transparent and flexible decision-making processes will be crucial for sustaining public trust.","42316486":"ID: 42316486\nTitle: The Emotional Experiences of Healthcare Professionals Working in Amyotrophic Lateral Sclerosis: A Systematic Review.\nAbstract: Healthcare professionals (HCPs) working with people living with amyotrophic lateral sclerosis (ALS) are often exposed to emotive circumstances including end of life care, trauma, loss, and death. Existing reviews have explored the emotional experiences of people living with ALS and their carers but have largely ignored healthcare staff and the impact of this work on them. This systematic review of qualitative research aims to explore the emotional experiences of and impact on HCPs working with people living with ALS using thematic synthesis (PROSPERO reference: CRD42025631749). Electronic databases were searched for journal articles and gray literature (Medline, Scopus, PsycINFO, Google Scholar, King's Fund Library Database, ProQuest Dissertations, Theses Global) for qualitative or mixed-methods studies exploring the emotional impact on HCPs working in ALS. Twelve studies were included, critically appraised, and analyzed. Four themes were identified. The emotional intensity due to the nature of ALS created challenges for HCPs, while they were also faced with absorbing the emotions of others. HCPs learned to balance their emotional involvement, and HCPs also described positive experiences and coping mechanisms. HCPs working in ALS experience multi-faceted emotional challenges, and they do describe positive emotional experiences within their roles. However, HCPs describe having few coping mechanisms and limited formal support systems in place to process the intense emotions or to guide their emotional involvement. The lack of support for staff may ultimately negatively affect patient care. There is an unmet demand for debriefing, supervision, and further training on how to deal with intense, distressing emotions.","42316902":"ID: 42316902\nTitle: The ALS Home Health and Durable Medical Equipment Medical Standard Expert Consensus Guideline.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease associated with escalating disability and complex care needs. Although most individuals with ALS reside at home, existing US guidelines primarily address clinic-based care and provide limited direction on medically necessary home health services and durable medical equipment (DME). The objective of this task force was to develop expert consensus guidance defining minimum medical standards for home health services and DME for individuals with ALS, with the goal of improving patient outcomes, safety, and quality of life. This guideline was developed by a multidisciplinary task force convened by the American Association of Neuromuscular and Electrodiagnostic Medicine (AANEM). The process incorporated a scoping literature review, stakeholder engagement (patients, caregivers, and advocacy groups), and iterative expert consensus. Recommendations were informed by clinical expertise, patient-centered priorities, and existing policy frameworks. This guideline outlines stage-responsive home healthcare recommendations spanning nursing, home health aides, physical and occupational therapy, speech-language pathology, respiratory therapy, nutritional support, and social work. It emphasizes proactive, anticipatory care aligned with the predictable trajectory of ALS, rather than being reactive based on functional decline. The document defines medically necessary DME across domains, including mobility, communication, respiratory support, and activities of daily living, advocating for timely access independent of restrictive payer criteria. Key principles include coordinated interdisciplinary care, continuous reassessment, caregiver support, and integration of palliative care. These recommendations establish a foundational standard for ALS home-based care in the United States. Adoption may reduce delays, prevent complications, and support sustained independence and dignity for individuals with ALS.","42318821":"ID: 42318821\nTitle: 3D-printed lab-on-chip platforms for the detection of neurodegenerative diseases: opportunities and challenges.\nAbstract: Neurodegenerative diseases (NDs) such as Alzheimer's, Parkinson's, and ALS remain some of the most challenging disorders to diagnose at an early stage. Conventional approaches rely on costly neuroimaging or invasive cerebrospinal fluid sampling, which limit accessibility and early intervention. Recent advances in 3D printing have enabled rapid prototyping of lab-on-chip (LOC) platforms that integrate microfluidics, biosensors, and biological models to detect disease-specific biomarkers with high sensitivity and throughput. Herein, we explore the synergistic role of 3D printing technologies and biomaterials in fabricating LOC systems for NDs. We highlight key biomarkers, and neuron- and organoid-on-chip platforms, and discuss the challenges and opportunities in clinical translation. By combining technical innovation in additive manufacturing with biological relevance, 3D-printed LOC devices represent a transformative approach toward precision diagnostics in neuro-medicine.","42320585":"ID: 42320585\nTitle: [Professional Health Literacy within the Academic Transition of Midwifery Education: Findings from a Quantitative Study of Midwifery Students in Germany].\nAbstract: Since 2020, midwifery has been the first health profession in Germany to be fully transferred into academic education. However, it remains unclear whether midwifery students acquire the professional health literacy required to meet the increasing challenges of the healthcare system, such as the substantial growth in available specialized knowledge and the evolving expectations of patients regarding care and participation in decision-making. Whether and how future midwives possess the necessary competencies to respond to these new challenges is reflected in their level of professional health literacy. The aim of this study is therefore to assess the current status of professional health literacy among students of midwifery science. Data collection was conducted as part of the HELPER study. A total of 140 midwifery students from Bavaria were included. Professional health literacy was measured using the PROF-HL-Q instrument, which comprises 34 items covering four domains. Results are presented descriptively. Correlation analyses were performed to identify potential associations with sociodemographic characteristics and study-related parameters. On average, students rated their professional health literacy positively, achieving scores between 51.4 and 78.7 out of 100 across the four domains. Patient-centered communication was perceived as the easiest domain, whereas professional digital health literacy was rated the most challenging. In particular, students reported difficulties in interpreting statistical results, dealing with misinformed patients, and supporting patients in finding digital health information. Overall, only weak correlations were observed with the variables examined. The findings indicate specific areas in which midwifery students' competencies require further strengthening and thus provide implications for curriculum development, particularly in light of ongoing digitalization and the continued professionalization of midwifery. Der Hebammenberuf ist seit 2020 der erste Gesundheitsfachberuf in Deutschland, der vollständig in die Akademisierung überführt wurde. Allerdings ist unklar, ob die angehenden Hebammen durch das Studium auch die notwendige professionelle Gesundheitskompetenz vermittelt bekommen, um den steigenden Herausforderungen des Gesundheitswesens begegnen zu können – etwa dem enormen Zuwachs an verfügbarem Fachwissen oder den veränderten Versorgungs- und Mitbestimmungsansprüchen von Patient/-innen. Ob und wie die nun angehenden Hebammen über die notwendigen Voraussetzungen verfügen, auf neue Herausforderungen des Gesundheitswesens reagieren können, wird durch die sogenannte professionelle Gesundheitskompetenz erfasst. Das Ziel der vorliegenden Arbeit ist es daher, den Status Quo der professionellen Gesundheitskompetenz von Studierenden der Hebammenwissenschaft aufzuzeigen.Die Erhebung erfolgte im Rahmen der HELPER-Studie. Es wurden 140 Hebammenstudierende aus Bayern eingeschlossen. Ermittelt wurde die professionelle Gesundheitskompetenz anhand des Erhebungsinstruments PROF-HL-Q, welches aus 34 Items besteht und vier Aufgabenbereiche umfasst. Die Ergebnisse werden deskriptiv dargestellt. Im Anschluss werden Korrelationsanalysen durchgeführt, um mögliche Zusammenhänge mit soziodemographischen Merkmalen und studienbezogenen Parametern zu identifizieren.Im Durchschnitt schätzen die Studierenden ihre professionelle Gesundheitskompetenz als positiv ein und erreichen in den vier Aufgabenbereichen zwischen 51,4 und 78,7 von 100 möglichen Punkten. Dabei fällt den Hebammenstudierenden die patientenzentrierte Kommunikation am leichtesten und die professionelle digitale Gesundheitskompetenz am schwersten. Besonders schwer fällt ihnen das Einordnen statistischer Ergebnisse, der Umgang mit falschinformierten Patient/-innen sowie die Unterstützung von Patient/-innen beim Finden digitaler Gesundheitsinformationen. Insgesamt zeigen sich nur geringe Korrelationen mit den getesteten Bezugsgrößen.Die Ergebnisse geben Hinweise darauf, in welchen Bereichen die Kompetenzen der Hebammenstudierenden noch gestärkt werden müssen und lassen somit Schlussfolgerungen für die Gestaltung der Lehrcurricula zu, besonders mit Blick auf die fortschreitende Digitalisierung und die weitere Professionalisierung des Hebammenberufes.","42333954":"ID: 42333954\nTitle: Thinning of the oral motor cortex is linked to impaired speech in amyotrophic lateral sclerosis.\nAbstract: Most individuals with amyotrophic lateral sclerosis (ALS) develop bulbar impairment as their disease progresses. The ALS Functional Rating Scale-Revised (ALSFRS-R) bulbar subscore and neurological examination of upper (UMN) and lower motor neurons (LMN) are routinely used to assess this dysfunction but have inherent limitations. Speech‑derived measures have shown promise for capturing bulbar decline with greater sensitivity, but their neurobiological correlates remain unclear. This study examined the associations between quantitative speech measures and cortical thinning in ALS. Data from the Canadian ALS Neuroimaging Consortium were analyzed. Speech measures were extracted from audio recordings of the standardized \"Bamboo Passage\". Cortical thickness was calculated from T1‑weighted MRI scans. General linear models first compared cortical thickness between patients with ALS and healthy controls. Associations between the speech measures and cortical thickness were then assessed within the ALS group. Patients with ALS showed cortical thinning across bilateral frontotemporal regions, with the largest clusters in the bilateral motor cortices. Reduced speaking and articulation rates were associated with thinning in both oral motor cortices. In contrast, the ALSFRS-R bulbar subscore and UMN and LMN bulbar burden showed no significant associations. Measures of pausing behavior were negatively associated with frontal cortical regions. Thinning of the oral motor cortex in ALS was linked to reduced oral motor function, supporting speaking and articulation rate as sensitive markers of bulbar motor neuron degeneration. These measures demonstrated neuroanatomical associations that the ALSFRS-R bulbar subscore and neurological examination findings did not, highlighting their potential value for monitoring bulbar dysfunction in ALS.","42334216":"ID: 42334216\nTitle: Tolerability, Safety and Effectiveness of Sigh Introduction During Non-Invasive Mechanical Ventilation Cycles in Patients With Amyotrophic Lateral Sclerosis.\nAbstract: Respiratory failure is the main cause of death in Amyotrophic lateral sclerosis (ALS), in which the physiological sigh reflex is impaired due to inspiratory muscle weakness. Aim of this study is to assess the tolerability, safety, and effectiveness of adding a sigh cycle to non-invasive mechanical ventilation (NIMV) settings in ALS patients. In this randomized, blind-controlled proof-of concept study, 44 consecutive ALS patients with indication for NIMV were randomized to: Group I: NIMV with Sigh cycles; Group II: NIMV without Sigh. The primary outcome was the reduction in the Oxygen Desaturation Index (ODI); secondary outcomes included: Overnight Oximetry (OvOx), Arterial blood gas (ABG), and Visual Analog Scale (VAS; 0-10) scores to assess sleep quality, symptom intensity, mask interface, and NIMV tolerance. Assessments were conducted at baseline, after NIMV adaptation (T1) and at 1-month follow-up (T2). The Sigh cycle was safe and well tolerated. No significant group differences were observed at T1 or T2 in the primary outcome ODI (median ΔODI: Group A:-4.2; Group B:-4.6: p = 0.54), as well as in the OvOx parameters and pO2 and pCO2 ABG values. At T2, secondary analysis showed a significant difference in HCO₃- in favor of the Sigh arm (ΔHCO3 -: -1.60 vs. 1.35 mmol/L, p = 0.042). Exploratory Cox-regression models suggested a potential independent effect of SIGH on survival. Sigh is safe, well tolerated in ALS patients. Although this study did not reach the primary outcome, we also cannot rule out that sigh doesn't benefit the patient.","42334507":"ID: 42334507\nTitle: Associations influencing quality of life in caregivers of patients with amyotrophic lateral sclerosis: a stress-process model approach.\nAbstract: Caring for patients with amyotrophic lateral sclerosis (ALS) involves demands that reduce caregivers' quality of life. Although caregiver burden and perceived social support was conceptualized as an independent correlate of quality of life rather than a factor operating primarily through caregiver burden. This study examined these associations within a stress-process framework in which perceived social support was conceptualized as an independent correlate rather than a buffering factor. This cross-sectional analytical study included 118 informal caregivers of patients with ALS. Primary stressors were defined as patient functional status (ALSFRS-R), caregiving duration, and communication difficulty. Caregiver burden (Zarit Burden Interview) was considered a secondary stressor. Physical and mental quality of life were assessed using the SF-12, and perceived social support was measured with the Multidimensional Scale of Perceived Social Support. Hierarchical regression analyses were performed to examine associations specified in the conceptual model while controlling for caregiver sociodemographic and socioeconomic variables. Additional mediation analyses were conducted to examine whether caregiver burden mediated the relationship between perceived social support and quality of life. Poorer patient functional status was significantly associated with higher caregiver burden, whereas communication difficulty showed a positive but non-significant association after adjustment for caregiver characteristics. Caregiver burden showed negative associations with both physical and mental quality of life. Perceived social support remained positively associated with quality of life after adjustment for caregiver burden and contributed additional explained variance in the models. Mediation analyses showed no evidence that caregiver burden mediated the association between perceived social support and either physical or mental quality of life. The findings are consistent with a stress-process framework in ALS caregiving, in which caregiver burden represents a central factor statistically associated with both caregiving stressors and quality of life, while perceived social support shows an independent association with quality of life. These findings suggest that both caregiver burden and perceived psychosocial resources may be relevant to caregiver well-being, although causal and intervention-related implications require further investigation. Caring for a person with amyotrophic lateral sclerosis (ALS) is physically and emotionally demanding, and many caregivers experience reduced quality of life. Previous studies have examined caregiver burden and social support separately, but it is not well understood how these factors work together to influence caregivers’ well-being. This study examines how disease-related challenges, caregiver burden, and perceived social support are connected, and how these factors jointly affect the physical and mental quality of life of ALS caregivers. The study tests a conceptual model proposing that caregiving challenges increase caregiver burden, which in turn affects quality of life, while perceived social support contributes directly to quality of life rather than simply reducing stress. Worse patient functioning and communication difficulties were linked to higher caregiver burden. Higher burden was associated with poorer physical and mental quality of life. Perceived social support remained positively related to quality of life even after accounting for caregiver burden. These findings suggest that improving social support and reducing caregiver burden are both important for maintaining quality of life among ALS caregivers.","42336630":"ID: 42336630\nTitle: Young people's sexual wellbeing: a systematic review of qualitative studies.\nAbstract: Young people's adverse sexual experiences contribute to a significant global mental health burden and detract from their quality of life. Sexual wellbeing connects sexual and mental health and can offer a novel perspective on drivers and impacts of young people's sexual behaviour. It is a promising means through which to shift public health focus from risk to aspects of sex relevant to broader wellbeing. This systematic review aimed to characterise sexual wellbeing for adolescents and emerging adults (aged 16-24 years). We searched four databases for peer-reviewed qualitative literature on young people's accounts relevant to sexual wellbeing published between 1988 and 2025. We intensity sampled and thematically synthesised studies against Mitchell et al's Sexual Wellbeing Conceptual Framework. PROSPERO registration: CRD42022315593. We thematically synthesised 93 papers, representing 3152 participants across 25 countries. Our synthesis characterises youth sexual wellbeing as feeling: congruence between one's sexual thoughts, feelings, values, behaviours and emerging identities; driven by curiosity or desire; capable of advocating for one's wants and boundaries; able to authentically express oneself; deserving of care, respect and support; and expectant of a positive sexual future. Women, sexual and gender minorities, sexual violence survivors, youth with disabilities or health conditions, and those in deprived or sexually conservative communities report additional barriers to wellbeing. This first-ever review of youth sexual wellbeing underscores its significance during this life stage, and outlines similarities and differences compared with adults. The findings demand a stronger focus on young people's priorities for sexual wellbeing to support their healthy development.","42338888":"ID: 42338888\nTitle: Interplay between B vitamins, fiber, and Bacteroides abundance: a predictive model for anxiety and depression in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and incurable neurodegenerative disease that not only affects motor function but is also associated with gastrointestinal and emotional disturbances. Recent research highlights the potential role of gut microbiota and diet in modulating these symptoms, suggesting a complex interaction between nutrition, intestinal health, and presence of anxiety and depression in ALS patients. This study aims to investigate the relationship between dietary intake, gut microbiota composition, and presence of anxiety and depression in patients with amyotrophic lateral sclerosis (ALS). A cross-sectional study conducted with a sample of 48 patients with bulbar-onset or spinal-onset ALS from different regions of Spain. Dietary intake was assessed through 24-h records and food frequency questionnaires, while anxiety and depression were evaluated using validated scales that formed a latent factor called emotional distress. Stool consistency was assessed following the Bristol Stool Scale and the abundance of bacterial microbiota was quantified. Confirmatory factor analysis identified a nutritional factor composed of vitamins B1, B2, B9, C, and fiber, revealing a significant inverse association with anxiety and depression levels. The predictive model revealed both direct and indirect effects of this factor on presence of anxiety and depression, mediated by Bacteroides abundance and stool consistency. This model explained 19% of the variance in psychological distress. Our findings suggest that a diet rich in B vitamins, C vitamin and fiber may help improve emotional well-being in patients with ALS, highlighting the importance of nutritional strategies, as well as the role of Bacteroides related to stool consistency in patients with ALS.","42341745":"ID: 42341745\nTitle: [Digital transformation in multiple sclerosis: Advances in diagnostics, monitoring and patient-centred care].\nAbstract: Digital transformation is fundamentally changing the diagnosis, monitoring and treatment of multiple sclerosis. The integration of multimodal data from imaging, laboratory tests, clinical assessments, patient-reported outcomes and continuous measurements via wearables is creating high-resolution, longitudinal profiles of disease progression. Based on this data, modern analysis methods and artificial intelligence enable predictive models for disease activity, progression and therapeutic response, supporting personalised decision-making. Digital patient pathways and patient portals open up new options for participatory, standardised care, while telemedicine, telerehabilitation and digital health applications complement care regardless of location and time. In research, real-world data, federated learning and virtual, decentralised studies are accelerating patient-centred evidence generation. Concepts such as the digital twin outline the next stage of development in simulation-based precision medicine. Key challenges relate to data protection and data security, data quality, interoperability, bias, transparency and the traceability of algorithmic decisions. Overall, digitalisation offers substantial opportunities to detect disease activity earlier, optimise treatment goals and improve quality of life and care - provided that technical, regulatory and ethical requirements are consistently addressed and translated into scalable care models.

Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1β, γ interferon (IFN-γ), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1β, IFN-γ, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1β and IFN-γ decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1β,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05).

Through their ability to recognise specific cis-elements in target transcripts, often via RNA-recognition motifs or other conserved domains, RBPs enable rapid cellular adaptation to stress and maintain proteostasis, particularly in post-mitotic tissues with limited transcriptional flexibility. Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing. Limitations of current models and priorities for future translational research are discussed.","42347833":"ID: 42347833\nTitle: Validation of the German version of the Dimensional Apathy Scale (G-DAS): Application in amyotrophic lateral sclerosis.\nAbstract: Apathy is a common behavioural impairment in neurodegenerative conditions and is conceptualized within the Dimensional Apathy Framework as comprising Executive, Emotional and Initiation subtypes. The Dimensional Apathy Scale (DAS) is widely used to assess these domains, yet no validated German version has been available. This study aimed to translate and validate the German DAS (G-DAS) in control participants (HC) and to characterize apathy profiles in German-speaking people with amyotrophic lateral sclerosis (pwALS). Seventy-seven HC and 32 pwALS completed self-rated and caregiver-rated measures of apathy, depression, disinhibition and executive dysfunction. The G-DAS was translated using a multi-round back-translation procedure. Psychometric validation was undertaken in the HC cohort. A subsample of HC matched to pwALS on age and sex was used for between-group comparisons and for deriving exploratory reference thresholds. The G-DAS demonstrated good to high internal consistency across subscales (α = .76-.85) and total scores (self-rated: α = .88; caregiver-rated: α = .86). Convergent validity was supported by significant correlations with the Apathy Evaluation Scale and Frontal Systems Behavior subscales, particularly for the Initiation and Executive subscales. Divergent validity was evidenced by the absence of associations with anxiety and depression. PwALS showed significantly higher Executive and Initiation apathy compared with matched HC, whereas Emotional apathy did not differ. Exploratory threshold scores derived from matched HC indicated that up to 47% of pwALS exhibited clinically elevated Initiation apathy. The G-DAS is a reliable and valid German-language measure of multidimensional apathy. It effectively captures the characteristic Executive and Initiation apathy profile in ALS, supporting its clinical and research utility.","42351263":"ID: 42351263\nTitle: Dynamic integration of skeletal muscle signals via extracellular vesicles in motor neuron diseases.\nAbstract: Extracellular vesicles (EVs) are heterogenous lipid bilayer-enclosed particles secreted by virtually all cell types. They encapsulate a diverse array of bioactive molecules, including proteins, lipids, nucleic acids, and metabolites, which can be transferred to recipient cells, thereby modulating their function and phenotype. In recent years, skeletal muscle-derived EVs (SkM-EVs) have emerged as key players in the bidirectional communication between skeletal muscle and motor neurons, contributing to the establishment and maintenance of neuromuscular homeostasis. Disruptions in this intercellular signalling have been implicated in the pathophysiology of motor neuron diseases (MNDs) such as spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS). In these contexts, SkM-EVs may contribute to disease progression by delivering pathogenic cargo, including misfolded proteins and aberrant RNAs, to motor neurons. A comprehensive understanding of SkM-EV biology, particularly their roles in neuromuscular communication, could offer critical insights into disease mechanisms and identify novel opportunities for biomarker discovery and therapeutic intervention. This review synthesizes current knowledge on the functional roles of SkM-EVs in motor neuron health and disease and evaluates their potential as diagnostic tools and therapeutic vectors in the context of MNDs.","42352907":"ID: 42352907\nTitle: The Dual Role of Glial Extracellular Vesicles in Neurodegeneration: Insights from iPSC-Based Models.\nAbstract: Extracellular vesicles (EVs) have emerged as key mediators of intercellular communication in the brain, with glial cell-derived EVs increasingly recognized for their roles in maintaining brain homeostasis and contributing to the progression of neurodegenerative diseases. By transferring a diverse cargo of bioactive molecules, including proteins, RNAs, and organelles, EVs influence recipient cell behavior and overall brain function. In neurodegenerative conditions, glial EVs can either propagate pathogenic signals or deliver neuroprotective and regenerative cues, depending on their cellular origin and molecular composition. This context-dependent heterogeneity highlights the need for physiologically relevant human models to investigate EVs biology. Human induced pluripotent stem cell (iPSC)-derived glial models provide a disease-relevant platform, as they recapitulate key pathological features of Alzheimer's disease (AD), Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS). When further integrated with brain organoid platforms, these iPSC-based systems enable the generation of three-dimensional environments that closely resemble in vivo EVs dynamics. Importantly, glial EVs can modulate cellular pathways involved in neuronal survival and function. Indeed, their potential to interact with and, under specific experimental conditions, traverse the blood-brain barrier (BBB) has contributed to growing interest in their application for biomarker discovery and therapeutic development. Engineered and patient-specific EVs derived from iPSCs are emerging as promising tools for targeted, cell type-specific, therapeutic approaches, although their clinical applicability still requires further validation. This review discusses the emerging evidence supporting the dual role of iPSC-derived glial EVs in health and disease, underscores the translational potential of iPSC-based platforms for mechanistic studies, and outlines their promise as precision medicine tools for diagnostics and therapy.","42356052":"ID: 42356052\nTitle: Association Between Clinical Dysphagia Assessment Tools and Videofluoroscopic Findings in Amyotrophic Lateral Sclerosis: A Retrospective Study.\nAbstract: Background and Objectives: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease frequently associated with dysphagia and aspiration risk. This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.","42360421":"ID: 42360421\nTitle: [Prevention instead of remediation-screening, lifestyle factors, and prostate care 2.0-transition of urology to healthcare coach : Holistic approach to prostate health].\nAbstract: Establishment of an organized, risk-adapted prostate cancer screening program in Germany could serve as a key entry point for preventive men's health. How can the introduction of an organized, risk-adapted prostate cancer screening program in Germany shape preventive urology of the future? This narrative review article is based on guidelines and expert consensus supported by a literature search in PubMed. The cited studies represent the most relevant work on this topic and were selected to illustrate developments and fundamental concepts; however, completeness is not claimed. Serum prostate-specific antigen (PSA) levels and prostate MRI not only identify patients at increased risk for prostate cancer but also offer insights into other urological conditions, such as lower urinary tract symptoms and hypogonadism. In analogy to other early detection strategies, PSA testing at the age of 45-50 years could serve as a simple triage test to guide risk-adapted follow-up and timely referral to urological care. Lifestyle factors-including regular physical activity, a balanced diet, and pelvic floor training-may favorably influence urological health and related outcomes. While organized prostate cancer screening has already been shown to improve cancer-specific mortality to a level comparable to mammography, a more holistic approach may further enhance its overall benefit. Urology has significant opportunities to actively promote healthy behaviors among aging men. The establishment of an organized prostate cancer screening program provides an ideal entry point for this purpose. Modern screening concepts should incorporate holistic health promotion for aging men alongside direct oncological endpoints. HINTERGRUND: Die Etablierung einer organisierten, risikoadaptierten Prostatakarzinomfrüherkennung könnte Grundlage einer präventiven Männergesundheit sein. Wie kann die Einführung einer organisierten, risikoadaptierten Prostatakarzinomfrüherkennung die präventive Urologie von morgen prägen? Dieser narrative Übersichtsartikel auf der Grundlage von Leitlinien und Expertenkonsens wird unterstützt durch eine Literaturrecherche auf PubMed (2000–2026). Die zitierten Studien stellen nach Meinung der Autoren die relevanten Arbeiten hierzu dar und wurden ausgewählt, um Entwicklungen und prinzipielle Konzepte zu veranschaulichen, beanspruchen jedoch keine Vollständigkeit. Der PSA-Wert (prostataspezifisches Antigen) und die MRT liefern nicht nur Hinweise auf ein Prostatakarzinom, sondern auch auf andere urologische Erkrankungen wie Miktionsbeschwerden oder Testosteronmangel. Parallel zu anderen Früherkennungsuntersuchungen könnte der PSA-Wert mit 45–50 Jahren als einfaches Triage-Tool fungieren, um risikoadaptierte Verlaufskontrollen sowie fachurologische Vorstellungen zu steuern. Lebensstilfaktoren wie Bewegung, eine gesunde Ernährung und Beckenbodentraining können urologische Erkrankungen und deren Folgen positiv beeinflussen. Durch eine organisierte Prostatakarzinomfrüherkennung kann das karzinomspezifische Mortalität bereits heute vergleichbar zur Mammographie verbessert werden, durch ein holistischeres Herangehen kann der Gesamtnutzen jedoch noch mehr gesteigert werden. Die Urologie hat große Chancen, die Gesundheitskompetenz des alternden Mannes, aber auch Früherkennungsmaßnahmen für andere Erkrankungen, aktiv zu fördern. Die organisierte Prostatakarzinomfrüherkennung könnte hierfür einen sinnvollen Einstieg darstellen. Moderne Früherkennungskonzepte sollten die ganzheitliche Gesundheitsförderung des alternden Mannes neben direkten onkologischen Endpunkten miteinbeziehen.","42360520":"ID: 42360520\nTitle: Comments on: Predictors of pathologic complete response in early-stage triple-negative breast cancer treated with neoadjuvant chemo-immunotherapy.\nAbstract: This correspondence comments on LeVee et al.'s real-world study of neoadjuvant chemo-immunotherapy in early-stage triple-negative breast cancer.

This research used patient-reported data to identify the most prevalent and impactful symptoms experienced by individuals with PD and determine the demographic and clinical characteristics that are associated with higher symptomatic burden. We conducted semistructured qualitative interviews of 20 individuals with self-reported PD, obtaining 2,978 quotes regarding potential symptoms of importance. Findings from these interviews informed the development of a cross-sectional survey study designed to asess the impact of these symptoms in a larger cohort. Four-hundred four participants with self-reported PD participated in the survey study, providing the prevalence and relative importance (0-4 scale) of 301 symptoms representing 14 symptomatic themes. We subsequently performed subgroup analysis to identify demographic and clinical characteristics that were associated with a higher prevalence of symptomatic burden in PD. The most prevalent symptomatic themes identified by participants were sleep disturbances and daytime sleepiness (87.0%) and fatigue (84.7%). The symptomatic themes with the greatest impact (0-4) on participants' lives were fatigue (1.34) and sleep disturbances and daytime sleepiness (1.29). A higher prevalence of disease burden across all symptomatic themes was most strongly associated with speech impairment, gait freezing, and a duration of tremor greater than 5 years. The impact of PD on the lives of those living with this disease is multisystemic, reaching beyond the cardinal motor symptoms. Fatigue, sleep disturbances, and daytime sleepiness are highly prevalent and important to this population.","42369228":"ID: 42369228\nTitle: Talking about the hypothetical future: Serious illness communication for residents living with dementia in long-term care homes - An integrative review.\nAbstract: In long-term care (LTC) homes, residents living with dementia frequently experience serious illness communication that is crisis-initiated and oriented to institutional documentation (e.g., transfer and resuscitation orders), rather than iterative, values-based discussions aligned with a palliative approach and substitute decision-making frameworks. Unpaid care partners often make high-stakes decisions with limited preparation, and residents are inconsistently included. To explore how serious illness communication occurs with residents living with dementia, unpaid care partners, and healthcare providers in LTC, and to identify practice-relevant communication strategies and contextual factors applicable to clinical practice. An integrative review following Toronto and Remington's six-stage methodology included 31 high-relevance studies (qualitative, quantitative, mixed methods, reviews, theoretical) published from 2015 to 2025 on serious illness, goals-of-care, or end-of-life communication in LTC dementia care. Directed content analysis was guided by Tarbi et al.'s basic science of communication in serious illness (lexical, non-lexical, contextual elements, and outcomes). Serious illness communication was predominantly biomedical and documentation-focused, often occurring at admission or during crises and directed mainly to unpaid care partners, with limited resident involvement. Lexical practices such as clear, jargon-free information, explicit invitations to discuss \"what matters most,\" and early conversations about hypothetical future scenarios enhanced trust, preparedness, and alignment of care with resident values. Non-lexical elements (tone, eye contact, pacing, use of silence) shaped perceived empathy but were seldom explicitly addressed by interventions. For LTC healthcare providers, embedding earlier, iterative serious illness communication, explicitly involving residents where possible, and cultivating both lexical and non-lexical skills are key to achieving relationship-centred, legally compliant, and goal-concordant palliative approaches to care.​. This review looked at how people talk about serious illness and end-of-life care with residents living with dementia in long-term care (LTC) homes, and how these conversations affect care decisions. Serious illness communication includes discussions about what matters most to residents as their dementia progresses, what kinds of treatments they would or would not want, and how unpaid care partners and healthcare providers can prepare for future changes and dying. The review found that these conversations in LTC usually happen late in the illness, often during admission to an LTC home or during a crisis and focus mainly on medical decisions or paperwork (for example, hospital transfer forms or resuscitation status). Residents with dementia are often not included directly and most conversations are held with unpaid care partners, who can feel unprepared or distressed. How healthcare providers communicate (by tone of voice, eye contact, body language, and use of silence) can strongly influence whether families feel heard, respected, and able to trust the team. The way LTC homes are organized also shapes these conversations. Staffing levels, continuity of staff, time pressures, leadership support, and charting systems all influence whether serious illness discussions are ongoing and person-centred, or brief, checklist-style tasks. When communication works well, unpaid care partners report better understanding of what to expect, more confidence in making decisions, and care that is better aligned with the resident’s values near the end-of-life.","42371002":"ID: 42371002\nTitle: [Communication in later life under institutional conditions : Professional perspectives on communication of ageing people with profound intellectual and multiple disabilities].\nAbstract: For people with (profound) intellectual and multiple disabilities verbal language is often not the primary means of communication. Communication is closely tied to familiar persons and the interpretation of individual forms of expression. In later life health-related changes, the loss of social relationships and institutional transitions can substantially impair communication. Based on group interviews with professionals this paper examines the significance of communication partners, the professional and institutional prerequisites for successful communication in later life and the institutional embedding of augmentative and alternative communication. In this study seven group interviews were conducted with professionals working in disability support services. Data were analyzed using structured qualitative content analysis. Professionals describe social relationships in later life as fragile and communication partners as often confined to institutional settings, which increases the importance of familiar caregivers for successful communication. They further emphasize experiential and specialist knowledge, resources and knowledge transfer across interfaces. Augmentative and alternative communication appears sustainable especially where it is institutionally embedded. In later life communicative participation among this group appears less as a matter of individual competence than as an organizational and knowledge-related task: it requires both preserving biographically developed interpretive knowledge and institutionally embedded augmentative and alternative communication. HINTERGRUND: Bei Menschen mit geistiger und komplexer Behinderung ist verbalsprachliche Kommunikation häufig nicht der zentrale Kommunikationsweg. Kommunikation ist eng an vertraute Personen, Kontexte und die Deutung individueller Ausdrucksformen gebunden. Im Alter können gesundheitliche Veränderungen, Verluste sozialer Beziehungen und institutionelle Wechsel die Kommunikation beeinträchtigen. ZIEL: Der Beitrag untersucht auf Grundlage von Gruppeninterviews mit Fachkräften die Bedeutung von Kommunikationspartner:innen, professionelle und institutionelle Voraussetzungen gelingender Kommunikation im Alter sowie die institutionelle Verankerung Unterstützter Kommunikation. Es wurden sieben Gruppeninterviews mit Mitarbeitenden der Behindertenhilfe geführt. Die Auswertung erfolgte mittels strukturierender qualitativer Inhaltsanalyse. Die Fachkräfte beschreiben soziale Beziehungen im Alter als fragil und Kommunikationspartner:innen häufig als auf institutionelle Räume verengt, wodurch vertraute Bezugspersonen für gelingende Kommunikation besondere Bedeutung gewinnen. Zudem betonen sie Erfahrungswissen, Fachkenntnisse, Ressourcen sowie Kooperation und Wissenssicherung an Schnittstellen. Unterstützte Kommunikation wird vor allem dort tragfähig, wo sie institutionell verankert ist. Kommunikative Teilhabe im Alter erscheint bei diesem Personenkreis weniger als Frage individueller Kompetenz denn als organisations- und wissensbezogene Gestaltungsaufgabe: Sie verlangt sowohl die Sicherung biografisch gewachsenen Deutungswissens als auch eine institutionell verankerte Unterstützte Kommunikation.","42375131":"ID: 42375131\nTitle: Beyond neurofilaments: a multidimensional blood signature for amyotrophic lateral sclerosis.\nAbstract: This scientific commentary refers to 'Blood-based biomarker discovery in motor neuron disease using nucleic acid-linked immuno-sandwich assay', by Bozkurt et al.

As a result, students lack knowledge about its practical tasks, meaning that the ÖGD is rarely considered when choosing a career. This situation contributes significantly to the shortage of young doctors in public health departments. Elective placements during the practical year are intended to attract students to the ÖGD; however, evaluations indicate that the offered places are not being filled, despite the positive assessment. Project description To promote interest in the ÖGD at an early stage and in a low-threshold manner, an extracurricular course was developed at Justus-Liebig-Universität Gießen as a supplementary elective in the interdisciplinary area of Health Economics, Health System, and Public Health. In the summer semester of 2025, a 90-minute bathing water inspection was held for the first time in cooperation with the Giessen Health Authority. The aim was to provide students with practical insights into the work of the ÖGD in the fields of water and environmental hygiene, while also establishing personal contact with the authorities' employees. Feedback from participants showed that the event was found to be enriching both professionally and in terms of career orientation. In contrast to clinical placements or PJ elective terms, the format allowed for very low-threshold access without requiring students to choose between other subject areas. Extracurricular elective courses such as bathing water inspections can serve as a complementary strategy to raise students' awareness of the ÖGD at an early stage and thus contribute to the long-term recruitment of young talent to public health service. Der Öffentliche Gesundheitsdienst (ÖGD) hat im Humanmedizinstudium bislang eine geringe Präsenz. Dadurch fehlt es Studierenden an Kenntnissen über seine praktischen Aufgaben, sodass der ÖGD bei der Berufswahl kaum berücksichtigt wird. Diese Situation trägt wesentlich zur ärztlichen Nachwuchslücke in den Gesundheitsämtern bei. Wahltertiale im Praktischen Jahr sollen Studierende für den ÖGD gewinnen, doch Auswertungen zeigen, dass die angebotenen Plätze nicht ausgeschöpft werden, obwohl die Evaluationen positiv ausfallen. Projektbeschreibung Um das Interesse am ÖGD frühzeitig und niederschwellig zu fördern, wurde an der Justus-Liebig-Universität Gießen ein extracurriculares Lehrangebot als ergänzendes Wahlangebot zum Querschnittsbereich 3 Gesundheitsökonomie, Gesundheitssystem und Öffentliches Gesundheitswesen entwickelt. Im Sommersemester 2025 fand erstmals eine 90-minütige Badegewässerbegehung in Kooperation mit dem Gesundheitsamt Gießen statt. Ziel war es, Studierenden praxisnah Einblicke in die Arbeit des ÖGD im Bereich Wasser- und Umwelthygiene zu ermöglichen und gleichzeitig den persönlichen Kontakt zu Mitarbeitenden der Ämter herzustellen.Die Rückmeldungen der Teilnehmenden zeigen, dass die Veranstaltung sowohl fachlich als auch in Hinblick auf die Berufsorientierung als bereichernd empfunden wurde. Im Unterschied zu Famulaturen oder PJ-Wahltertialen ermöglicht das Format einen sehr niederschwelligen Zugang, ohne dass Studierende sich gegen andere Fachgebiete entscheiden müssen.Extracurriculare Wahlangebote wie die Badegewässerbegehung können als ergänzende Strategie dienen, Studierende frühzeitig für den ÖGD zu sensibilisieren und damit langfristig zur Nachwuchsgewinnung beizutragen.","42379746":"ID: 42379746\nTitle: Navigating Unanticipated Non-recurrent Laryngeal Nerves in Thyroid Surgery: Strategies for Preservation and Anticipation.\nAbstract: This study aimed to investigate the incidence, anatomical characteristics, and clinical implications of non-recurrent laryngeal nerves (NRLNs) discovered during thyroid surgeries and autopsies. A total of 2,215 thyroid surgeries and 194 autopsies were reviewed, identifying 17 and 1 case of NRLN, respectively. Data regarding nerve anatomy, associated vascular anomalies, and patient medical history were collected and analyzed. Neck ultrasound examinations were subsequently performed on the 17 living patients, 5 months to 19 years post-surgery, by three radiologists specializing in head and neck soft-tissue imaging. Two radiologists were blinded to the specific nerve anatomy, while one was unblinded. Vascular anomalies of the aortic arch were described only by the unblinded radiologist. Among the 17 NRLN cases, three (16.7%) exhibited normal vascular anatomy. According to Toniato et al.'s classification, one case each was categorized as 2a, 2b, and one case involved a coexisting right NRLN and right RLN. No definitive recurrent paresis was observed, with only one patient experiencing transient palsy lasting 5 weeks. Histological evaluation revealed no structural differences between NRLN and RLN variants, although their epineurium and adventitia were notably thinner than those of the vagal nerve. Achieving blood-free conditions for meticulous dissection and preserving sympathetic nerve branches are essential for optimal functional outcomes in thyroid surgeries involving NRLNs.","42381263":"ID: 42381263\nTitle: Longitudinal Dynamics of Polyglutamine-Expanded ATXN3 in Biofluids of Spinocerebellar Ataxia Type 3.\nAbstract: Spinocerebellar ataxia type 3 (SCA3), the most common autosomal dominant ataxia, is driven by the accumulation of polyglutamine-expanded (polyQ) ATXN3 proteins. While promising as biomarkers, their longitudinal trajectories across multiple biofluids remain poorly defined. To quantify polyQ ATXN3 levels in cerebrospinal fluid (CSF), plasma, and urine within a comprehensive cohort, utilizing serial measurements to map protein dynamics. We employed a validated immunoassay to quantify polyQ ATXN3 in 97 symptomatic and 13 presymptomatic SCA3 patients, correlating levels with clinical features, ancestry, disease status, and longitudinal progression. Asian participants exhibited lower plasma but elevated urinary polyQ ATXN3 levels relative to other ancestries. While CSF levels were higher in symptomatic patients at baseline, they showed a significant longitudinal decline. PolyQ ATXN3 is a viable multi-biofluid biomarker. Declining CSF levels likely reflect neurodegeneration, supporting its role in tracking progression and emphasizing the need for ancestry-based adjustment in trials. © 2026 International Parkinson and Movement Disorder Society.","42382427":"ID: 42382427\nTitle: Simultaneous ultrasound and needle electromyography recording of fasciculations in amyotrophic lateral sclerosis.\nAbstract: Fasciculations can be detected using both muscle ultrasonography and needle electromyography, yet the correspondence between ultrasonographically observed fasciculations (U-fas) and needle electromyography-detected fasciculation potentials (N-fas) has not been clarified. This study investigated their correspondence using fully synchronized recordings. Adult patients showing fasciculation-like contractions on muscle ultrasonography were enrolled; all were subsequently diagnosed with amyotrophic lateral sclerosis. Ultrasound and needle electromyography were recorded simultaneously in up to three muscles per patient, with a recording duration of 3 min per muscle. For each ultrasonographically observed fasciculation, the presence of a corresponding electromyographic event and contraction duration assessed by M-mode imaging were evaluated. Ten patients with amyotrophic lateral sclerosis were included. A total of 472 focused U-fas events were analyzed. Corresponding N-fas were detected in 437 events, yielding an overall concordance rate of 92.6% (95% confidence interval, 90.2-95.0%). U-fas contraction duration ranged from 343 to 971 ms, whereas N-fas duration ranged from 10.9 to 76.4 ms. The number of phases of N-fas observed during U-fas events ranged from 1 to 10. Most ultrasonographically observed fasciculations corresponded to electromyography-detected events on simultaneous recording. Ultrasonographically detected fasciculations may serve as a supplementary indicator of lower motor neuron involvement in amyotrophic lateral sclerosis.","42383305":"ID: 42383305\nTitle: TDP-43 proteinopathy as a biomarker and therapeutic target in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common form of adult-onset motor neuron disease, characterised by the degeneration of upper and lower motor neurons. The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.","42383366":"ID: 42383366\nTitle: Response to Yu et al.'s Commentary on Effectiveness of Oral Care Intervention and Safe Swallowing Education on Post-Extubation Dysphagia in ICU Patients: A Nurse-Led Quasi-Experimental Study.\nAbstract: ","42385017":"ID: 42385017\nTitle: Understanding patients' experiences and needs around decision-making for bulbar symptom management at a multidisciplinary ALS clinic.\nAbstract: This study explored the decision-making experiences of people living with amyotrophic lateral sclerosis (ALS) for managing bulbar symptoms and their perceived needs for decision-making support from healthcare professionals. An interpretive, descriptive qualitative study was conducted. We recruited adult patients with ALS with and without any bulbar symptoms from a multidisciplinary ALS clinic in Central Canada. Patients were interviewed using a semi-structured guide. Reflexive thematic analysis was used to analyze study data. Recruitment ceased when information power was reached. Twelve participants were interviewed. Three themes were identified for patient's decision-making experiences and needs: (1) Disease uncertainty hinders decision-making; (2) Quality information triggers decision-making; and (3) Personal values and beliefs inform decision-making. To reduce psychological consequences of disease uncertainty and complexity on bulbar-related decision-making, patients emphasized the need for specific and contextualized information and healthcare professional supports aligned with their decision-making styles and approaches, highlighting the importance of a person- and family-centred approach to ALS care. Patients with amyotrophic lateral sclerosis (ALS) experience uncertainty with bulbar disease progression and interventions, which hinders both conversations and decisions about intervention.Patients want healthcare professionals to provide information about how intervention options and intervention timing were tailored to their individual situations.Patients also want healthcare professionals to adapt their communication and guidance to patients’ decision-making styles and approaches.Attention to patient’s broader social context is needed for decision-making to support person- and family-centred ALS care.Findings highlight the need for more healthcare professional education and research to improve decision-making support in a multidisciplinary ALS clinic setting.","42385762":"ID: 42385762\nTitle: Global, regional, and national burden of tuberculosis and multidrug-resistant tuberculosis by HIV status, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023.\nAbstract: Tuberculosis (TB) is the leading global cause of death from a single infectious agent. Recent reductions in global health funding have threatened TB control, making comprehensive assessment of TB, HIV-related TB, and drug-resistant TB burdens before these disruptions essential for shaping effective responses. The WHO End TB Strategy sets targets of a 95% reduction in TB deaths and a 90% reduction in TB incidence between 2015 and 2035. Using results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2023, this study aims to assess the burden of TB and multidrug-resistant TB (MDR-TB) across 204 countries and territories, and to evaluate progress towards the WHO End TB incidence and mortality targets. We quantified TB mortality using the Cause of Death Ensemble modelling platform with global vital registration, surveillance, verbal autopsy, and minimally invasive tissue sampling data. For TB morbidity estimation, we simultaneously modelled incidence, prevalence, and mortality by age and sex using DisMod-MR 2.1. A population attributable fraction (PAF) approach was applied to stratify morbidity and mortality estimates by HIV and drug-resistance status. We also calculated disability-adjusted life-years (DALYs) as the sum of years of life lost and years lived with disability. For the risk factor analysis, a comparative risk assessment framework was used and PAFs were derived for alcohol use, smoking, and high fasting plasma glucose to determine the proportion of TB burden associated with these risk factors. In 2023, there were an estimated 9·11 million (95% uncertainty interval 8·04-10·3) incident cases of all-form TB, 1·22 million (0·98-1·49) deaths, and 54·6 million (43·8-65·5) DALYs globally. HIV-related TB comprised 781 000 (690 000-879 000) incident cases and 210 000 (142 000-279 000) deaths, contributing 11·0 million (7·56-14·3) DALYs. MDR-TB accounted for 466 000 (198 000-1 080 000) incident cases, 102 000 (31 700-238 000) deaths, and 3·96 million (1·31-9·01) DALYs. From 2015 to 2023, global all-form TB incidence rates declined by 19·2% (17·8-20·5) and deaths declined by 22·6% (4·7-35·7); declines were larger for drug-susceptible TB than for MDR-TB. Sub-Saharan Africa and south Asia had the highest mortality burdens in 2023; reductions in all-form TB incidence and mortality were uneven between 2000 and 2023, with limited progress in both measures in Latin America and the Caribbean. Removing smoking, alcohol use, and high fasting plasma glucose would reduce global TB deaths to 768 000 (592 000-970 000) and DALYs to 34·9 million (27·8-43·8) in 2023; MDR-TB deaths would decrease to 77 200 (23 400-183 000) and DALYs to 3·12 million (1·03-7·29). Global progress towards WHO End TB targets is disparate and fragile. Although many regions achieved meaningful gains, others have stagnated in recent years. The complexity of TB prevention is amplified by divergent MDR-TB trends, the persistent burden of HIV, and growing exposure to modifiable risk factors. Recent volatility in global health financing threatens to further destabilise this vulnerable epidemiological landscape; concerted action is urgently needed to temper disruptions and preserve progress.

However, no Early Palaeolithic sites in Central Asia are anchored with reliable age constraints, including the thick loess-palaeosol sections in Tajikistan that recorded early human activities and environmental changes over multiple glacial-interglacial cycles. This lack of absolute age constraints is presently a key factor limiting our understanding of the early human occupation history of this region. Here, we provide a comprehensive description and an absolute chronological framework for the Early Palaeolithic Karatau Culture; defined by the rich lithic assemblages found in palaeosols in the Khovaling Loess Plateau, Tajikistan. Age constraints are provided through multi-method analysis of three loess-palaeosol sections in the Khovaling Loess Plateau, combining luminescence ages, cosmogenic 26Al-10Be concentrations, and magnetostratigraphic boundaries into a probabilistic inverse age-depth model. This model shows that the Karatau Culture flourished with the onset of Marine Isotope Stage 15, thrived during Marine Isotope Stage 13 and 11, but disappeared around onset of Marine Isotope Stage 10. We frame the archaeological occupations within local and regional ecological settings to better understand the drivers of Pleistocene human migrations in Central Asia.","42387528":"ID: 42387528\nTitle: Fidelity in the context of adapting a digital intervention for depression from an evidence-based in-person format in Vietnam.\nAbstract: Digital interventions have emerged as a promising way to better meet growing population mental health needs. Our team developed a digital depression intervention (VMood; smartphone app) in Vietnam. VMood is adapted from an evidence-based in-person intervention (SSM) developed in Canada and uses cognitive behaviour therapy (CBT) principles with remote coaching by non-specialist providers. Fidelity-adaptation is a major tension in implementation science. Fidelity is the degree an intervention is designed and delivered as intended. Conversely, adaptations are sometimes made for specific contexts. This paper aims to identify key elements of fidelity-adaptation - the degree VMood is consistent theoretically with the SSM intervention and practically with implementing digitally in the Vietnamese setting. This study uses Perez et al.'s modified version of Carroll et al.'s Implementation Fidelity Framework, focusing on Objective 1: Conceptualizing what intervention fidelity means in this specific context (across modes and cultures) and Objective 2: Conducting fidelity testing to identify key elements along the fidelity-adaptation continuum. Ethnographic data from team meetings explored essential components that must remain intact and necessary adaptations. Non-specialist providers and app users from Vietnam tested VMood. Experts familiar with CBT provided theoretical feedback. Interviews or focus groups were conducted with all participants to gain insights into the adaptive intervention. Qualitative data were analyzed using thematic content analysis. Participants agreed that VMood captures the essential theoretical components from SSM, noting certain elements of SSM (e.g., change in human contact to online) could not be replicated digitally. Participants also presented adaptation suggestions unique for the digital format to strengthen VMood's acceptability, including keeping the app simple by reducing the amount of text; incorporating more dynamic content (e.g., animations) to increase engagement; and including more culturally appropriate scenarios. Finally, key potential moderators to fidelity reported included quality of program delivery and participant responsiveness. Findings identified intervention specific elements of fidelity-adaptation and showed that VMood retained essential components of SSM while incorporating adaptations to support implementation within the Vietnamese context. With the global increase in digital health services adapted from in-person delivery, understanding how to balance fidelity with necessary adaptations is important both theoretically and practically.","42387809":"ID: 42387809\nTitle: Muscle-Specific Kinase Signaling and Its Therapeutic Potential.\nAbstract: The function of the neuromuscular junction (NMJ) is compromised in many neuromuscular diseases (NMDs) such as autoimmune or congenital myasthenia gravis (MG), amyotrophic lateral sclerosis (ALS), spinal muscular atrophy (SMA), and muscular dystrophies. The NMJ contains muscle-specific kinase (MuSK), which is a critical regulator of NMJ integrity and function. Activating the MuSK signaling cascade may have therapeutic potential in several of these NMDs that are characterized by impaired neuromuscular communication. The MuSK signaling cascade consists of different components and can be activated with interventions at different levels. In the past years, different therapeutic strategies using an engineered recombinant agrin comprised of the C-terminal fragment of the protein (mini-agrin), gene therapy of key proteins in this pathway, agonist MuSK antibodies, and SRC homology 2 domain-containing phosphotyrosine phosphatase 2 (SHP2) inhibitors have been further developed for this purpose. Each of these strategies engages distinct signaling components: mini-agrin, both as recombinant protein and gene therapy, enhances agrin-Lrp4-MuSK interaction; Dok7 gene therapy amplifies MuSK phosphorylation; Lrp4 gene therapy enhances agrin responsiveness; MuSK agonist antibodies bypass upstream defects and promote downstream signaling; SHP2 inhibitors prolong the duration of active MuSK signaling. These therapeutic strategies have ameliorated NMJ integrity and function in several preclinical models of MG, motor neuron diseases, and muscular dystrophies. In this review, we highlight MuSK signaling as a possible therapeutic target, describe the therapeutic efficacy of intervention in MuSK signaling in different NMDs, and present an outlook on future clinical development.","42388397":"ID: 42388397\nTitle: Long-term use of rozanolixizumab in generalised myasthenia gravis: final pooled analysis of the phase III MycarinG study and two open-label extensions.\nAbstract: Myasthenia gravis (MG) is a rare autoimmune disease characterised by fluctuating and fatigable muscle weakness. In the randomised, double-blind phase III MycarinG study, one 6-week rozanolixizumab cycle significantly improved MG-specific outcomes versus placebo and was generally well tolerated in patients with generalised MG (gMG). To assess the efficacy and safety of cyclic rozanolixizumab treatment. A pooled analysis of the MycarinG, MG0004 and MG0007 studies. Following MycarinG, eligible patients could enrol in the open-label extension studies MG0004 or MG0007 to receive rozanolixizumab 7 or 10 mg/kg. In MG0004, patients received chronic weekly treatment for ⩽52 weeks. In MG0007, after an initial 6-week treatment cycle, subsequent cycles were based on symptom worsening (investigator's discretion). Final efficacy data were pooled across MycarinG, MG0004 (first 6 weeks) and MG0007 for patients receiving ⩾2 symptom-driven cycles. Efficacy endpoints included change from baseline (CFB) in MG Activities of Daily Living (MG-ADL), MG Composite (MGC) and Quantitative MG (QMG) scores. Safety outcomes were assessed in patients who received ⩾1 cycle with a ⩽8-week follow-up period across MycarinG and MG0007. Overall, 188 patients received ⩾1 cycle and 129 received ⩾2 symptom-driven cycles. Across Cycles 1-13, mean (standard deviation) CFB to Day 43 in MG-ADL score ranged from -3.2 (3.3 (n = 113; Cycle 3)) to -6.0 (3.9 (n = 24; Cycle 12)). Consistent improvements in MGC and QMG scores were also observed across repeated cycles. Treatment-emergent adverse events (TEAEs) were experienced by 175/188 (93.1%) patients; most mild or moderate. Incidence remained stable with repeated cyclic treatment among patients who remained in the study at each cycle. The most common TEAE was headache (n = 94/188 (50.0%)). Repeated rozanolixizumab treatment cycles demonstrated consistent, clinically meaningful improvements in MG-specific outcomes as early as 1 week after the first infusion. Rozanolixizumab was generally well tolerated with an acceptable safety profile, supporting its long-term use as a treatment option for adults with gMG. ClinicalTrials.gov: NCT03971422; NCT04124965; NCT04650854. Long-term treatment with cycles of rozanolixizumab improved symptoms in patients with generalised myasthenia gravis in a combined analysis of final data from the MycarinG study and its two extension studies Generalised myasthenia gravis (gMG) is an autoimmune disease that damages the connections between nerves and muscles, causing muscle weakness. In the MycarinG study, treatment with rozanolixizumab once a week for 6 weeks was better at improving gMG symptoms than placebo in adults with gMG. After MycarinG, patients could enter the extension studies MG0004 and MG0007. These studies assessed the side effects of long-term rozanolixizumab treatment and measured patients’ symptoms to see whether rozanolixizumab remained effective. In MG0004, patients received rozanolixizumab once a week for up to 52 weeks. In MG0007, patients received rozanolixizumab once a week for 6 weeks, termed a treatment cycle. After the first treatment cycle, patients only received more cycles if their symptoms worsened. We looked at data from patients who received repeated rozanolixizumab treatment cycles across MycarinG, MG0004 (first 6 weeks only) and MG0007. Treatment side effects and gMG symptoms were assessed. Overall, 129 patients received two or more rozanolixizumab cycles due to worsening symptoms. We saw consistent improvements in gMG symptoms across multiple measures; improvements were maintained over repeated treatment cycles. Altogether, we assessed 188 patients for side effects; 175 (93.1%) reported a side effect, most of which were mild or moderate in severity. The most common side effect was headache. The number of reported side effects and how bad they were did not change much across treatment cycles among patients who stayed in the study at each cycle. In the first year of treatment, patients had an average of four treatment cycles. Based on this, rozanolixizumab treatment would be expected to follow a repeated pattern of 6 weeks on treatment and 6–8 weeks off in the first year. Together, these data suggest that repeated rozanolixizumab cycles can be used for long-term treatment in patients with gMG.","42389895":"ID: 42389895\nTitle: Nanoscale morphological and structural analysis of round and donut oligomers formed by C-terminal domain of TDP-43.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), Alzheimer's disease (AD), limbic predominant age-related TDP-43 encephalopathy (LATE), and Parkinson's disease are associated with an abrupt aggregation of TAR DNA-binding protein 43 (TDP-43). Although molecular mechanisms of this pathological aggregation remain unclear, accumulated evidence suggests that the C-terminus domain (C-terminal domain (CTD)) is the trigger of TDP-43 self-assembly into toxic oligomers and fibrils. While the secondary structure and morphology of protein fibrils have been well documented, very little is known about TDP-43 oligomers. This is primarily because of the transient nature and low concentrations of these protein species. In the current study, we utilize nano-infrared spectroscopy, also known as atomic force microscopy-infrared (AFM-IR) spectroscopy, to investigate the morphology and secondary structure of CTD of TDP-43 oligomers formed at the early and middle stages of protein aggregation. This innovative technique allows us to resolve both morphology and secondary structure of individual protein aggregates. We found that at the early stage of protein aggregation, CTD of TDP-43 formed two morphologically different protein aggregates: donut-like (DO) and round (RO) oligomers. DO yielded fibrillar species, while RO persisted throughout the entire course of CTD TDP-43 self-assembly.","42392979":"ID: 42392979\nTitle: Deletion of exon 2 in ALS-linked Sptlc1 causes lethality in homozygous mice but not in heterozygotes.\nAbstract: Mutations in the human SPTLC1 gene have recently been linked to early-onset amyotrophic lateral sclerosis (ALS), characterized by global atrophy, motor impairments, and symptoms such as tongue fasciculations. All known ALS-linked SPTLC1 mutations cluster within exon 2, and a specific variant, c.58G>T, results in exon 2 skipping. However, it is unclear how the exon 2 deletion affects SPTLC1 function in vivo and contributes to ALS pathogenesis. Leveraging the high genomic sequence similarity between mouse and human SPTLC1, we created a novel knock-in mouse model with a CRISPR/Cas9-mediated deletion of exon 2 in the endogenous murine Sptlc1 locus. Although heterozygous mice did not develop motor defects or ALS-like neuropathology, homozygous mutants died prematurely. These findings provide valuable insights into SPTLC1 exon 2 biology and serve as a useful resource for future mechanistic studies.","42393685":"ID: 42393685\nTitle: Structural-functional network decoupling in early stage amyotrophic lateral sclerosis reveals cell-type specific transcriptional signatures.\nAbstract: Amyotrophic lateral sclerosis (ALS) involves widespread brain network dysfunction, yet the molecular mechanisms linked to these alterations remain poorly understood. We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology.","42393765":"ID: 42393765\nTitle: Phenotype-specific muscle proteomic profiling in titinopathies.\nAbstract: Titinopathies are complex neuromuscular disorders with multiple phenotypes. The gene's size, comprising 364 exons, as well as the protein's size of 3.8 MDa and its extensive network of protein interactors, are key factors underlying this complexity. Various phenotypes characterize titinopathies, and this study focuses on two of them: arthrogryposis and myofibrillar myopathies. The protein deregulations associated with these two phenotypes remain unknown or have been minimally explored; however, understanding these consequences is essential for better characterizing the pathophysiological aspects of these titinopathies.The objective was to analyze protein deregulations in two cohorts of French patients with titinopathies exhibiting the arthrogryposis and myofibrillar myopathy phenotypes, and to compare them with control individuals. Protein extracts were obtained from muscle biopsies of patients, and changes in protein levels within these two groups were analyzed by mass spectrometry. The results indicate specific deregulations in each group. The networks analyzed revealed deregulation of proteins involved in fibrosis mechanisms or in the actomyosin complex for the arthrogryposis phenotype. Regulation of the muscle contraction system through deregulation of proteins involved in the cytoskeleton is impacted in patients with myofibrillar myopathy. The proteins that are quantitatively abnormal in these two groups also provide insights into the major signaling networks disrupted in titinopathies. These findings will contribute to a more precise characterization of titinopathies, enabling the identification of phenotype-specific biomarkers and potentially guiding the search for targeted therapies for these neuromuscular disorders.","42393897":"ID: 42393897\nTitle: Bioinformatic Identification of Shared Gene Networks Between Weaning- Induced Intestinal Inflammation and Neuroinflammatory-Related Pathways.\nAbstract: Weaning is a critical developmental stage that can trigger intestinal inflammation through disruption of microbial homeostasis, immune responses, and epithelial barrier integrity. While numerous studies have explored gene expression changes during weaning in animals, no comparable analyses have been conducted in humans. Given the close physiological and genetic similarity between pigs and humans, piglet data were employed to investigate the molecular mechanisms underlying weaning-induced intestinal inflammation and its potential links to neurological pathways. A curated set of 117 differentially expressed genes related to gut inflammation was collected from bibliographic sources. Protein-protein interaction network analysis was performed using NetworkAnalyst and Cytoscape, followed by hub gene selection and functional enrichment using KOBAS, ClusterProfiler, and StringApp. Among the identified hub genes, SOD1, CAT, TNF, CXCR4, TLR2, and TGFB1 play key roles in oxidative stress, immune response, glial regulation, and neuroinflammatory signaling. Enrichment analysis revealed significant associations with pathways such as Amyotrophic Lateral Sclerosis, TGF-β signaling, Folate and Vitamin B12 metabolism, and Inflammatory Bowel Disease, as well as biological processes like gliogenesis, hypoxia response, and cytokine signaling. These findings suggest that intestinal inflammation during weaning may have systemic implications, highlighting shared molecular pathways relevant to neuroinflammatory-related processes. This study provides new insight into the genetic and molecular landscape of weaning-induced inflammation and its broader systemic effects. The identified shared molecular pathways may provide a foundation for future experimental studies investigating the broader biological implications of early-life intestinal inflammation.","42394053":"ID: 42394053\nTitle: Use and Usability of Wearable Devices in Assistive Living: A Scoping Review.\nAbstract: This paper describes a scoping review that explored the use and usability of wearable devices in assistive living with a focus on barriers to the real-world use of this technology in the home for the elderly. Published research was reviewed from the databases: PubMed, CINAHL, IEEE Xplore, and Web of Science. Using Arksey's et al.'s scoping review methodology relevant studies were identified, resulting in 37 reviewed for thematic analysis. The thematic analysis resulted in specific themes to barriers and facilitators in usability. Themes include privacy and security, technical challenges, providing a sense of safety and continued independence, and knowing connection to support is available if required. Wearable technology can positively contribute to elder care but a number of key issues and barriers remain.","42394935":"ID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.","42394962":"ID: 42394962\nTitle: Decremental responses following repetitive nerve stimulation in spinal and bulbar muscular atrophy.\nAbstract: The presence of decremental responses following repetitive nerve stimulation (RNS) in amyotrophic lateral sclerosis (ALS) is well established. However, in spinal and bulbar muscular atrophy (SBMA), a rare X-linked recessive lower motor neuron disease, the incidence and distribution of decremental responses across different muscles have not been thoroughly investigated. Patients with SBMA were retrospectively identified in our database. RNS at a frequency of 3 Hz was performed on five muscles: the abductor pollicis brevis (APB), abductor digiti minimi (ADM), upper trapezius, deltoid, and facial muscles (frontalis or nasalis). A total of forty patients were identified. A significant (> 5%) decremental response in at least one muscle was observed in all patients. It was observed more frequently in proximal muscles than in distal muscles: deltoid (86%), trapezius (70%), facial muscles (44%), APB (37%) and ADM (25%). The magnitude of the decremental response in the deltoid was significantly higher than that in the other muscles. Our results demonstrated that decremental responses were frequently observed in patients with SBMA, with a distribution pattern similar to that in ALS. The fact that the decremental responses are observed in SBMA having an extremely chronic course would be relevant for the pathophysiological mechanism of the decremental response. The RNS findings provide valuable insights into the pathological mechanisms of SBMA and may contribute to the development of future treatments.","42395430":"ID: 42395430\nTitle: ADAR2-Mediated RNA Editing Promotes TDP-43 Nuclear Export and Alters RNA Binding.\nAbstract: TAR DNA binding protein - 43 (TDP-43) nuclear loss is a pathological hallmark of amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and related neurodegenerative disorders. While the consequences of TDP-43 dysfunction have been well-characterized, the mechanisms driving TDP-43 mislocalization remain poorly understood. Previous observations of altered localization and function of the adenosine-to-inosine (A-to-I) RNA editing enzyme adenosine deaminase acting on RNA 2 (ADAR2) in ALS/FTD tissue prompted us to investigate whether dysregulated RNA editing contributes to pathological TDP-43 nucleocytoplasmic trafficking. TDP-43 cytoplasmic mislocalization was assessed following ADAR2 and TDP-43 co-overexpression in HEK293T cells and a Drosophila model co-overexpressing human TDP-43 and dADAR in motor neurons. We further evaluated TDP-43 mislocalization through both HeLa cell assays and interspecies heterokaryon assays. Next, we assessed TDP-43 binding to A-to-I edited RNA oligomers through electrophoretic mobility shift assays (EMSAs), and investigated inosine-containing RNAs in vivo via TDP-43 RNA immunoprecipitation followed by sequencing (RIP-seq) datasets from human TDP-43-expressing Drosophila . Finally, RNAseq and enhanced cross-linking and immunoprecipitation (eCLIP-seq) were performed in SH-SY5Y cells overexpressing three ADAR2 variants with differing editing activity to identify editing-related transcriptional alterations and RNAs differentially bound to TDP-43. ADAR2 overexpression reduced the nucleocytoplasmic (N:C) ratio of TDP-43 in HEK293T cells in a ADAR2 catalytic activity- and TDP-43 RNA-binding capacity-dependent manner. Drosophila motor neurons overexpressing dADAR also exhibited decreased nuclear TDP-43. Interspecies heterokaryons and permeabilized HeLa cell assays demonstrated that catalytically active ADAR2 and synthetic inosine-containing RNA oligomers, respectively, enhance nuclear export of endogenous TDP-43. EMSAs revealed preferential binding of TDP-43 to inosine-containing RNAs relative to unedited RNAs, and analysis of Drosophila RIP-seq datasets demonstrated enrichment of edited transcripts within TDP-43-bound RNAs. Finally, RNAseq and eCLIP-seq analyses identified editing-dependent alterations in gene expression and TDP-43 RNA-binding profiles in SH-SY5Y cells overexpressing active ADAR2 variants. Together, our findings identify A-to-I RNA editing as a previously unrecognized regulator of TDP-43 localization and RNA interactions. These results support a model where altered RNA editing modifies TDP-43-RNA interactions, promoting increased nuclear export of TDP-43. Broadly, our work highlights RNA editing dysregulation as a potential contributor to early pathogenic mechanisms underlying TDP-43 proteinopathies.","42396333":"ID: 42396333\nTitle: The Target ALS Global Natural History Study: Cross-platform proteomics to accelerate biofluid biomarker and drug target discovery in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal, rapidly progressive neurodegenerative disease of motor neurons for which therapeutics are limited. Improved biomarkers are imperative to improve patient care and therapeutic development. Here, we employed 35-plex isobaric tandem mass tag labeling based on isobutyl-proline reporter group (TMTpro) to perform unbiased proteomic analysis of cerebrospinal fluid (CSF) and plasma from control (n= 28, n= 31) and sporadic ALS (sALS) (n= 39, n= 41), from the Target ALS Global Natural History Study (TALS GNHS). We identified 2,875 proteins in CSF and 1,118 proteins in plasma and identified known and novel differentially expressed proteins (DEPs) between controls and sALS, some of which were orthogonally validated using immunoassay. Comparison of TMTpro-MS and Olink proximity extension assay proteomics revealed common and non-overlapping differentially expressed proteins illustrating strengths unique to each platform. This initial cross-sectional proteomic study of biofluids from the TALS GNHS, with unrestricted availability of study results to the research community, highlights the potential of this resource as a potent platform for ALS biomarker discovery.","42397425":"ID: 42397425\nTitle: [Real-world experience with aflibercept 8 mg for treatment of neovascular age-related macular degeneration after 12 months].\nAbstract: The phase 3 clinical trial PULSAR demonstrated extended treatment intervals with aflibercept 8 mg in treatment-naïve eyes with neovascular age-related macular degeneration (nAMD) in a large proportion of the cohort, with good drug safety. Early clinical experience in real-world settings confirmed the efficacy in both treatment-naïve and pretreated patients but no data on longer observation periods are available yet. The aim of the study was to investigate the efficacy, treatment frequency and tolerability of aflibercept 8 mg over a period of 12 months in a group of pretreated nAMD patients. A retrospective study of 73 eyes with nAMD and pretreatment with anti-VEGF switched to aflibercept 8 mg. Eyes were initially uploaded with 3 monthly intravitreal injections (IVI), followed by a pro re nata (PRN) regimen. Outcome parameters included visual acuity development and central retinal thickness (CSRT) after upload and 12 months, treatment frequency in the year before and after switching to aflibercept 8 mg, and the overall tolerability of the drug. Of the initial 73 eyes, 27 eyes (37.0%) were still receiving aflibercept 8 mg after 12 months. In these eyes CSRT was reduced from 387.9 ± 138.4 µm initially to 305.5 ± 93.2 µm after upload and 328.9 ± 105.6 µm after 12 months (p < 0.001). Visual acuity remained stable (p > 0.05). Compared to the year prior to switching, the injection frequency was reduced from 8.2 ± 2.1 to 6.9 ± 1.0 IVIs (p < 0.005). During the observation period, a total of 5 eyes (6.8%) developed noninfectious intraocular inflammation (IOI), with all cases completely regressing with topical treatment. These results confirm a good efficacy of aflibercept 8 mg for the treatment of nAMD with reduced injection frequency after 12 months of treatment in a portion of pretreated eyes that were often previously refractory to treatment. Longer observation intervals and experience with other treatment regimens are necessary to confirm this observation. HINTERGRUND: Die klinische Phase-3-Studie PULSAR zeigte, dass bei therapienaiven Patienten mit neovaskulärer altersbedingter Makuladegeneration (nAMD) eine Behandlung mit Aflibercept 8 mg in einem Großteil der Kohorte verlängerte Injektionsintervalle bei guter Verträglichkeit des Medikaments ermöglicht. Erste klinische Erfahrungen im Real-World-Setting konnten die Wirksamkeit sowohl bei therapienaiven als auch vorbehandelten Patienten bestätigen, allerdings liegen noch keine Daten zu längeren Beobachtungszeiträumen vor. Ziel der Studie war die Untersuchung der Therapiewirksamkeit, Injektionsfrequenz sowie Verträglichkeit von Aflibercept 8 mg in einem Zeitraum von 12 Monaten bei einem Kollektiv vorbehandelter nAMD-Patienten. Retrospektive Analyse von 73 Augen mit nAMD und vorausgegangener Anti-VEGF-Therapie, die auf Aflibercept 8 mg umgestellt wurden und nach einem Upload aus 3 monatlichen intravitrealen Injektionen (IVOMs) im Pro-re-nata(PRN)-Schema weiterbehandelt wurden. Untersucht wurden die Visusentwicklung und die zentrale Netzhautdicke (CSRT) nach Upload und nach 12 Monaten, die Injektionshäufigkeit im Jahr vor sowie nach Umstellung auf Aflibercept 8 mg sowie die Verträglichkeit des Medikaments. Von initial 73 Augen wurden nach 12 Monaten noch 27 Augen (37,0 %) mit Aflibercept 8 mg behandelt. Bei diesen Augen reduzierte sich die CSRT von initial 387,9 ± 138,4 µm auf 305,5 ± 93,2 µm nach Upload sowie auf 328,9 ± 105,6 µm nach 12 Monaten (p < 0,001). Der Visus blieb stabil (p > 0,05). Die Injektionsfrequenz sank im Vergleich zum Vorjahr von 8,2 ± 2,1 auf 6,9 ± 1,0 IVOMs (p < 0,005). Im Beobachtungszeitraum entwickelten insgesamt 5 Augen (6,8 %) eine nichtinfektiöse intraokuläre Inflammation (IOI), die in allen Fällen durch topische Therapie vollständig regredient war. Die Ergebnisse bestätigen bei einem Teil der vorbehandelten, oft zuvor therapierefraktären Augen mit nAMD eine gute Wirksamkeit von Aflibercept 8 mg bei gleichzeitiger Reduktion der Injektionsfrequenz über 12 Monate. Längere Beobachtungszeiträume und Erfahrungen mit anderen Therapieschemata sind notwendig, um diese Beobachtung zu bekräftigen.","42399082":"ID: 42399082\nTitle: Radiologically inserted gastrostomy in advanced amyotrophic lateral sclerosis: clinical outcomes.\nAbstract: To evaluate survival and clinical outcomes in patients with amyotrophic lateral sclerosis (ALS) undergoing radiologically inserted gastrostomy (RIG) and to describe outcomes in patients in whom gastrostomy was indicated but not performed. This retrospective observational cohort study included patients with ALS followed by a multidisciplinary palliative care team between 2018 and 2020. Patients were classified according to gastrostomy status (RIG vs no RIG). Clinical data, respiratory support, nutritional status and survival outcomes were collected from medical records. Survival was analysed from gastrostomy indication using Kaplan-Meier curves stratified by baseline non-invasive ventilation (NIV) use. Among 155 patients with ALS, RIG was indicated in 53 and performed in 45; eight patients died before the procedure. 65 patients did not undergo gastrostomy. Median survival after RIG was 14.7 months, compared with 8 months in non-RIG patients who died. Baseline NIV use was associated with longer survival. No major safety concerns were identified. RIG appears to be a safe and feasible option in advanced ALS. Multidisciplinary care with integrated palliative involvement may facilitate referral, optimise nutritional support and support shared decision-making aligned with patients' goals of care. Further prospective studies are needed to confirm benefits and identify intervention timing.","42399152":"ID: 42399152\nTitle: Macrophage inclusions in patients undergoing antisense oligonucleotide therapy for ALS or SMA: A retrospective and transversal study.\nAbstract: Intrathecal antisense oligonucleotides (ASOs) have revolutionized the management of genetic motor neuron diseases. Nusinersen is approved for spinal muscular atrophy (SMA) caused by SMN1 mutations, and tofersen for amyotrophic lateral sclerosis (ALS) linked to SOD1 mutations. Since their approval, some studies reported the presence of macrophagic inclusions in cerebrospinal fluid (CSF) of patients treated with ASOs, first in nusinersen-treated patients and more recently in those receiving tofersen. These findings remain poorly characterized, and their clinical significance is unclear. We first conducted a retrospective study in 21 patients (132 CSF samples): six treated with tofersen (every 4 weeks) and 15 with nusinersen (every 4 months). CSF samples were analyzed for macrophagic inclusions, their time of onset, and persistence over time. To assess clinical and inflammatory correlates of macrophagic inclusions, we then performed an analysis of CSF inflammatory biomarkers and serum ferritin and neurofilament light chain tests in 18 of these patients still under treatment. In tofersen-treated patients, macrophagic inclusions were consistently observed and persisted over time, except in one case. In nusinersen-treated patients, inclusions were rare and transient. An inflammatory CSF profile was associated with the presence of inclusions, but their cellular nature remained undetermined. Notably, tofersen-treated patients with \"tofersenophages\" exhibited favorable clinical responses. Macrophagic inclusions appear more frequent in the CSF of tofersen-treated patients than previously reported. While their origin remains unclear, they seem linked to CSF inflammation without precluding a beneficial therapeutic response.","42399593":"ID: 42399593\nTitle: Early and severe masticatory muscle involvement in SOD1-ALS: a case report with biomarker-clinical dissociation.\nAbstract: ","42404161":"ID: 42404161\nTitle: Perspective and quality of life in amyotrophic lateral sclerosis patients undergoing percutaneous endoscopic gastrostomy.\nAbstract: Percutaneous endoscopic gastrostomy (PEG) is commonly used to manage dysphagia and nutritional failure, which are among the most frequent and severe complications of amyotrophic lateral sclerosis (ALS). While several studies assessed PEG indications, outcomes, and prognostic factors, there is no evidence regarding ALS patients' perspectives and health-related quality of life (HRQoL) associated with PEG. This study included 48 consecutive ALS patients. At the 1-month follow-up after PEG, patients and their caregivers completed a PEG satisfaction questionnaire regarding their decision to proceed with the PEG-tube placement. HRQoL was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and the Short Form-36 (SF-36). In total, 77.1% of patients and 88.9% of caregivers confirmed that they would prefer to have a PEG tube placed again if required (p > 0.001); 93.8% of patients felt that PEG made feeding easier, exerting a positive effect on overall wellbeing (83.3%) and increasing survival rates (93.8%) (p > 0.001); 54.2% felt that PEG was cosmetically acceptable. Consistent positive rates were reported by caregivers. The GIQLI digestion subscale values significantly improved from baseline (28.3; SD = 6.6) to discharge (30.97, SD = 5.84) and were maintained at 1-month follow-up (30.21, SD = 6.7; p = 0.014). Conversely, in follow-up assessments, we observed a significant reduction in the SF-36 physical component summary (PCS) subscale (baseline = 33.3; 1-month follow-up = 28.61; p = 0.032), which was accompanied by a significant worsening in the GIQLI physical dimension subscale (baseline = 9.63; 1-month follow-up = 7.38; p = 0.044). This study provides preliminary evidence that ALS patients have a positive perspective on PEG positioning, which may also have a beneficial effect on HRQoL related to gastrointestinal function.","42404433":"ID: 42404433\nTitle: Beyond motor neurons: peripheral TDP-43 pathology in skeletal muscle and intramuscular nerves in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a progressive neurodegenerative disease characterized by accumulation of the 43-kDa TAR DNA-binding protein (TDP-43). This neuropathological signature has been well documented within the CNS; however, recent findings indicate that the phosphorylated TDP-43 additionally deposits in peripheral tissues, including skeletal muscle and intramuscular nerves. These data warrant a change of view from a neurocentric perspective of amyotrophic lateral sclerosis pathogenesis towards a broader concept of TDP-43 proteinopathy extending both within and beyond the nervous system. In this review, we focus on current evidence supporting the presence of TDP-43 pathology in amyotrophic lateral sclerosis skeletal muscle, examining its topographic distribution, molecular characteristics and associations with intramuscular nerve bundles. We also discuss the susceptibility of intrinsic muscle cells, disrupted axonal transport and impairment in protein quality control. Phosphorylated TDP-43 pathology in muscle biopsies from amyotrophic lateral sclerosis patients has emerged as a promising tool in the early diagnosis of the disease. Moreover, we discuss the relevance of these findings to amyotrophic lateral sclerosis pathogenesis and potential therapeutic implications.","42404435":"ID: 42404435\nTitle: Value of synaptic proteins as biomarkers in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis is a heterogeneous and rapidly progressing neurodegenerative disorder with limited treatment options. Therefore, there is a critical need for biomarkers that capture the diverse pathophysiological mechanisms underlying disease onset and progression. Emerging evidence suggests that synaptic dysfunction is an early disease mechanism in amyotrophic lateral sclerosis. Using homebrew immunoassays, we explored a panel of pre- and post-synaptic proteins in cerebrospinal fluid of patients with amyotrophic lateral sclerosis (N = 57) and controls (N = 36). The potential value as a biomarker was explored by correlating cerebrospinal fluid levels with clinical parameters and established biomarkers for amyotrophic lateral sclerosis. Higher levels of Neurogranin (NRGN) (P = 0.003) and Vesicle-associated membrane protein 2 (VAMP2) (P = 0.014) were observed in patients with amyotrophic lateral sclerosis compared with controls. VAMP2, Synaptosome-associated protein 25 kDa (SNAP25) and β-synuclein (SNCB) correlated with individual relative disease stage, but none of the biomarkers correlated with disease progression rate. High levels of SNAP25 predicted worse survival in a univariate and stepwise multivariable analysis, but significance did not persist upon including Neurofilament light chain (NfL) levels. Synaptic proteins did not correlate with cerebrospinal fluid levels of neurofilaments or biomarkers of neuroinflammation, suggesting that they reflect different pathological mechanisms in amyotrophic lateral sclerosis. Our findings warrant further investigation to determine whether increased cerebrospinal fluid levels of synaptic proteins reflect synaptic breakdown or active release of synaptic proteins. This will help elucidate how synaptic dysfunction or damage contributes to elevated levels of synaptic markers in amyotrophic lateral sclerosis, and its underlying value as biomarker.","42404802":"ID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-ΔNLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-ΔNLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-ΔNLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.","42405014":"ID: 42405014\nTitle: Cholesterol in amyotrophic lateral sclerosis: a bystander, a biomarker, or a target?\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron loss. In addition to the different pathogenic mechanisms, in recent years, increasing attention has been directed toward the role of lipid metabolism in ALS pathogenesis, although the clinical relevance of lipid alterations in ALS may differ from their well-established role in cardiovascular disease. This review critically examines the multifactorial relationship between cholesterol and ALS through three perspectives: (1) as a risk factor for disease onset, (2) as a prognostic biomarker of disease progression, and (3) as a potential therapeutic target. Epidemiological and genetic studies suggest a complex and sometimes contradictory association between lipid profile and ALS risk. Elevated LDL-cholesterol and total cholesterol have been linked to increased disease susceptibility in some cohorts, with Mendelian randomization studies supporting a potential causal role. Conversely, evidence regarding HDL-cholesterol remains conflicting and may be influenced by sex-specific and metabolic factors. As a prognostic biomarker, hyperlipidemia has been variably associated with prolonged survival in ALS patients; however, these findings often lose significance after adjusting for body mass index and nutritional status, suggesting that lipid levels may reflect systemic metabolic reserve rather than directly modulating disease progression. Pharmacological modulation of cholesterol reveals further complexity. While statins are generally not associated with increased ALS risk in clinical studies, preclinical models show divergent effects: some statins accelerate disease progression, while others like lovastatin may be protective. Other lipid-lowering drugs, including fibrates and PCSK9 inhibitors, may also influence ALS-related pathways beyond cholesterol lowering, although their potential role remains to be clarified.","42405987":"ID: 42405987\nTitle: Feasibility and sensitivity of a multimodal digital endpoint panel for amyotrophic lateral sclerosis: a prospective cohort study.\nAbstract: Background: The use of digital technology may improve monitoring of amyotrophic lateral sclerosis (ALS) but a multimodal approach is likely required to capture the full disease phenotype. We evaluated the feasibility of a multimodal home monitoring protocol in ALS. Methods: We conducted a 3-month prospective cohort study at the University Medical Center Utrecht, Netherlands, with monthly home assessments of spirometry, accelerometry, speech, and questionnaires on functioning. The primary outcome was protocol adherence, defined as percentage of completed assessments. Secondary outcomes included acceptability ((totally) agree, neutral, (totally) disagree), and perceived burden, ranging from 0 (no burden) to 10 (extremely burdensome). Exploratory analyses were performed to evaluate changes in digital endpoints using linear mixed-effects models. Findings: Fifty patients with ALS were included (January 2023 - June 2025), of whom 47 (94%) completed the 3-month follow-up. Overall adherence was 83.2% (95% CI 76.9-88.6) and did not differ across modalities (p = 0.75). Adherers did not differ from non-adherers in either demographic or disease characteristics. In month 3, 93.0% to 95.3% of patients considered monthly remote assessments as acceptable, with a mean burden score of 2.0 (95% CI 1.7 to 2.3); burden was highest for speech (2.5) and the lowest for questionnaires (1.5). Digital endpoints showed significant change over 3 months (all p < 0.05). Interpretation: This study demonstrates good adherence and acceptability of a multimodal remote monitoring protocol. Digital endpoints offer an innovative approach to capturing disease progression. Future research should assess its long-term feasibility, added value, and integration alongside established clinical outcomes.","42407013":"ID: 42407013\nTitle: Role of the Upper Motor Neuron in the Generation of Fasciculations in Early Disease Stages of Amyotrophic Lateral Sclerosis.\nAbstract: The origin of fasciculation potentials (FPs) in the early stages of amyotrophic lateral sclerosis (ALS) remains a subject of debate. We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders.","42407404":"ID: 42407404\nTitle: The contribution of trapezius and sternocleidomastoideus motor evoked potentials in the diagnosis of Amyotrophic lateral sclerosis.\nAbstract: We aimed to evaluate the role of corticobulbar motor evoked potentials (MEPs) as an objective electrophysiological measure to support clinical assessment of upper motor neurons in amyotrophic lateral sclerosis (ALS). Seventy-three patients with ALS and 44 healthy individuals with similar age and sex underwent transcranial magnetic stimulation with MEP recordings from the sternocleidomastoideus (SCM), trapezius, and abductor pollicis brevis muscles. Corticobulbar involvement was defined by prolonged cortical MEP latency or central motor conduction time (CMCT) or absence of MEP responses. Awaji-Shima diagnostic categories were evaluated before and after the incorporation of corticobulbar MEP abnormalities. Corticobulbar MEP abnormalities were significantly more frequent in patients with ALS than in controls. Prolonged SCM-MEP latency and CMCT were the most sensitive electrophysiological markers of corticobulbar involvement. When interpreted alongside clinical upper motor neuron signs, corticobulbar MEP abnormalities facilitated upward diagnostic reclassification within the Awaji-Shima framework. One-fifth of patients who were initially classified as possible or probable ALS were reclassified as probable ALS and definite ALS, respectively, following inclusion of SCM- and trapezius-MEP abnormalities. Corticobulbar MEP assessment provides objective electrophysiological support for upper motor neuron dysfunction and enhances diagnostic sensitivity when used in conjunction with the Awaji-Shima diagnostic framework. This study demonstrates that electrophysiological assessment of the corticobulbar pathway using SCM- and trapezius-MEPs provides objective evidence of upper motor neuron dysfunction in ALS.","42409979":"ID: 42409979\nTitle: [Psychotropic drug research in Germany: challenges of early benefit assessment and precision psychiatry].\nAbstract: The path to more precise and innovative psychotropic drugs is arduous and lengthy due to the complexity of mental illnesses and high regulatory hurdles. Nevertheless, several drugs have been developed and approved in the USA and the EU in recent years; however, not all of them were able to prevail in the benefit assessment in Germany. In order to exchange ideas about new precision medicine approaches as well as problems in the development and market access of psychotropic drugs and their possible solutions, the German Society of Psychiatry and Psychotherapy, Psychosomatics and Neurology (DGPPN) in cooperation with the House of Pharma & Healthcare hosted the round table on the future of psychotropic drug research in Frankfurt on 24 August 2023. Participants from clinical care, academic research, the pharmaceutical industry and patient representatives came together. What initiatives are necessary in the field of psychiatry research and regulation in order to successfully develop psychotropic drugs in Germany and to be able to introduce them into care? The article represents a synthesis of the lecture and discussion contributions of the 1‑day event. Current challenges are due to the fact that the biological mechanisms of mental illnesses are complex and heterogeneous and are insufficiently mapped by the current diagnostic entities. The benefit assessment of a preparation by the Federal Joint Committee (G-BA) often fails if an appropriate comparator therapy (zVT) cannot be reasonably selected or tested in a study. Platform studies (APT), which test the efficacy of several preparations at the same time with a control arm, can speed up the approval process and are meaningful. Consultations by the G‑BA in advance should be binding. The integration of empirical expertise can significantly enrich psychotropic drug research. Continuous dialogue between authorities, economy, science, politics and representatives of those affected is needed to promote the development and approval of psychotropic drugs and thus improve the quality of life of patients. HINTERGRUND: Der Weg zu präziseren und innovativen Psychopharmaka ist aufgrund der Komplexität psychischer Erkrankungen und hohen regulatorischen Hürden mühsam und langwierig. Dennoch wurden in den letzten Jahren mehrere Medikamente entwickelt und in den USA bzw. der EU zugelassen; sie konnten sich in Deutschland jedoch nicht alle in der Nutzenbewertung durchsetzen. Um sich über neue präzisionsmedizinische Ansätze sowie Probleme bei der Entwicklung und dem Marktzugang von Psychopharmaka und deren Lösungsmöglichkeiten auszutauschen, veranstaltete die Deutsche Gesellschaft für Psychiatrie und Psychotherapie, Psychosomatik und Nervenheilkunde (DGPPN) in Kooperation mit House of Pharma & Healthcare am 24.08.2023 den Runden Tisch zur Zukunft der Psychopharmakaforschung in Frankfurt. Teilnehmende aus klinischer Versorgung, akademischer Forschung, Pharmaindustrie und Betroffenenvertretung kamen zusammen. Welche Initiativen sind im Bereich Psychiatrieforschung und Regulatorik notwendig, um Psychopharmaka in Deutschland erfolgreich zu entwickeln und in die Versorgung einbringen zu können? Der Beitrag stellt eine Synthese der Vortrags- und Diskussionsbeiträge der eintägigen Veranstaltung dar. Aktuelle Herausforderungen liegen darin begründet, dass die biologischen Mechanismen psychischer Erkrankungen komplex und heterogen sind und mit den aktuellen diagnostischen Entitäten nur unzureichend abgebildet sind. Die Nutzenbewertung eines Präparates durch den Gemeinsamen Bundesausschuss (G-BA) scheitert oftmals, wenn eine zweckmäßige Vergleichstherapie (zVT) nicht sinnvoll ausgewählt oder in einer Studie geprüft werden kann. Plattformstudien (APTs), die mehrere Präparate gleichzeitig mit einem Kontrollarm auf ihre Wirksamkeit überprüfen, können das Zulassungsverfahren beschleunigen und sind aussagekräftig. Beratungen durch den G‑BA im Vorfeld sollten verbindlich sein. Die Einbindung von Erfahrungsexpertise kann die Psychopharmakaforschung wesentlich bereichern. Es bedarf eines kontinuierlichen Dialogs zwischen Behörden, Wirtschaft, Wissenschaft, Politik und Betroffenenvertretern, um die Entwicklung und Zulassung von Psychopharmaka voranzutreiben und damit die Lebensqualität von Patientinnen und Patienten zu steigern.","42410270":"ID: 42410270\nTitle: [The digital patient journey in radiological emergencies : Massive hemoptysis as a stress test of interoperability].\nAbstract: Massive hemoptysis is a life-threatening emergency in which the risk of asphyxiation predominates over blood loss. The situation becomes particularly challenging when a patient must be transferred from an external facility and clinically relevant information is incomplete. The initial diagnostic workup already begins prior to transfer to a specialized center. Initial priorities are oxygenation, correct patient positioning, and early airway protection. Depending on the local infrastructure, computed tomography (CT) angiography and bronchoscopy are the preferred modes of imaging. Structured, digital transfer of information, results, and imaging data without loss of data is paramount. In peripheral or systemic bleeding, bronchial artery embolization is the first-line therapeutic option and should be performed at a specialized center. A superselective technique, strict nontarget prevention, and adherence to established standard operating procedure (SOP) principles are essential. Massive hemoptysis is an example for the digital patient journey in radiological emergencies: when preliminary diagnostics are performed at an external hospital and definitive treatment is provided at a specialized center, the structured and rapid transfer of clinical information to that center is critical for quality of treatment. Emergency datasets on the electronic health card, the electronic patient record, and technical standards (FHIR, DICOM, and DICOMweb) are clinically relevant. European infrastructures (MyHealth@EU, European Health Data Space) may support the future of structured access to key clinical information and direct exchange of imaging data; however, they have not yet been fully integrated into routine emergency radiological practice. In radiological emergencies, interoperability is not merely a technical feature but a safety-relevant infrastructure component. It improves data triage, reduces media discontinuity, and may help prevent unnecessary repeat imaging. In radiological emergencies, it must be assessed at an early stage whether further treatment in an interventional center is necessary. In these cases, relevant data and clinical information should be transferred in a structured and fully digital manner without loss of information. KLINISCHES PROBLEM: Massive Hämoptyse zählt zu den vital bedrohlichen Situationen in der Notfallmedizin, da primär die Asphyxiegefahr und erst nachrangig der Blutverlust im Vordergrund steht. Besonders herausfordernd sind Versorgungssituationen außerhalb des gewohnten Behandlungskontexts, etwa wenn ein Patient in ein Zentrum verlegt werden muss und relevante Informationen nicht vollständig vorliegen. Die initiale Diagnostik beginnt bereits außerhalb eines spezialisierten Zentrums. Vorrang haben Oxygenierung, korrekte Lagerung, Absaugmanagement und eine niedrige Schwelle zur Atemwegssicherung. Je nach lokaler Infrastruktur können erste bildgebende und endoskopische Maßnahmen, insbesondere Computertomographie(CT)-Angiographie und Bronchoskopie, erfolgen. Eine strukturierte und verlustfreie Übermittlung von Vorinformationen, Befunden und Bilddaten ist entscheidend. Die definitive Versorgung massiver Hämoptysen mit bronchialer oder nichtbronchial-systemischer Blutungsquelle sollte in einem Zentrum mit entsprechender Expertise erfolgen. Die Bronchialarterienembolisation stellt die etablierte First-Line-Therapie dar. Entscheidend sind eine superselektive Katheterisierung, die Vermeidung von Non-Target-Embolisationen sowie die Beachtung standardisierter sicherheitsrelevanter Standard-Operating-Procedures (SOP). Damit wird die massive Hämoptyse zu einem exemplarischen Fall für die digitale Patientenreise im radiologischen Notfall: Wenn initiale Diagnostik und definitive Therapie an unterschiedlichen Versorgungsorten stattfinden, ist ein strukturierter und rascher Transfer klinischer Informationen für die Behandlungsqualität unmittelbar relevant. DIGITALE INFRASTRUKTUR UND INTEROPERABILITäT: Heute sind vor allem der Notfalldatensatz auf der elektronischen Gesundheitskarte, die elektronische Patientenakte sowie etablierte technische Standards (FHIR, DICOM, DICOMweb) praxisrelevant. Europäische Infrastrukturen (MyHealth@EU, European Health Data Space) eröffnen darüber hinaus eine wichtige Zukunftsperspektive für den grenzüberschreitenden und standardisierten Austausch klinischer Informationen und Bilddaten, befinden sich jedoch noch nicht in einer flächendeckend etablierten notfallradiologischen Routine. Interoperabilität ist im radiologischen Notfall keine rein technische Zusatzfunktion, sondern sicherheitsrelevante Infrastruktur. Sie verbessert die Datentriage, reduziert Medienbrüche und kann eine unnötige wiederholte Bildgebung vermeiden. EMPFEHLUNG FüR DIE PRAXIS: Im radiologischen Notfall ist frühzeitig zu prüfen, ob eine Weiterbehandlung in einem interventionellen Zentrum erforderlich ist. Dafür sollten relevante Daten und klinische Informationen strukturiert und möglichst medienbruchfrei übermittelt werden.","42411482":"ID: 42411482\nTitle: Amyotrophic Lateral Sclerosis as a Systemic Disease: Why Integrative and Microbiome-Focused Approaches Deserve Re-Evaluation.\nAbstract: Despite decades of intensive research, therapeutic advances in amyotrophic lateral sclerosis (ALS) remain limited. Increasing evidence suggests that ALS is a multisystem disorder involving motor neuron degeneration, immune dysregulation, skeletal muscle pathology, and gastrointestinal dysfunction, thereby challenging the adequacy of current therapeutic strategies. Complementary and alternative medicine (CAM) approaches are widely used by patients with ALS. However, their efficacy remains controversial owing to limited clinical evidence and methodological limitations. The multicomponent herbal medicine and system-level characteristics of CAM conceptually align with the emerging view of ALS as a multisystemic disease. The involvement of gut microbiome dysbiosis in the pathophysiology of ALS has provided a unifying biological framework linking the peripheral, metabolic, and neuroinflammatory processes. These findings suggest that the combination of CAM and conventional therapy may serve as a potential integrative approach to target gut-brain-muscle interactions and systemic disease pathways. This article highlights critical gaps in the existing evidence and proposes that microbiome-focused, biomarker-driven clinical trials are essential to thoroughly evaluate CAM-based interventions in ALS. Embracing a system-oriented therapeutic framework may help address the complexity of ALS beyond traditional neuron-centered approaches.","42411953":"ID: 42411953\nTitle: Reduced Soluble Ubiquilin2 in Amyotrophic Lateral Sclerosis Carrying Ubiquilin2 (P494L) Mutation: Clinicopathological and Biochemical Evidence From an Autopsy Case.\nAbstract: We report the clinicopathological and biochemical findings of ALS associated with a UBQLN2 P494L mutation. Autopsy revealed widespread TDP-43 pathology and UBQLN2-positive inclusions. Immunoblot analysis demonstrated a marked reduction of soluble UBQLN2, supporting functional UBQLN2 insufficiency as a pathogenic mechanism underlying TDP-43 aggregation.","42412610":"ID: 42412610\nTitle: Striatal neuron dysfunction in C9ORF72-FTD/ALS is driven by AIS and potassium channel dysregulation.\nAbstract: Frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) form a neurodegenerative spectrum characterized by progressive cognitive, behavioral, and motor decline, yet the contribution of the striatum to disease pathophysiology remains poorly understood. Here, we generate inhibitory striatal medium spiny neurons (MSNs) from human induced pluripotent stem cells carrying the C9ORF72 repeat expansion, the most common genetic cause of FTD/ALS, and compare them with isogenic-corrected, control, and patient-derived motor neurons. Using whole-cell electrophysiology, pharmacological manipulation, and high-resolution imaging, we identify a vulnerability of C9ORF72 MSNs to develop intrinsic hypoexcitability with linked synaptic dysfunction. These abnormalities are associated with axon initial segment shortening and altered voltage-gated potassium channel function relative to control and isogenic-corrected neurons. Pharmacological modulation partially restores action potential waveform properties, indicating that key electrophysiological abnormalities are reversible. These findings identify the striatum as a critical site of dysfunction in FTD/ALS and highlight striatal excitability as a potential therapeutic target.","42412831":"ID: 42412831\nTitle: OrgNet+: towards robust protein stability prediction with convolutional neural networks.\nAbstract: Predicting the effect of single-point mutations on protein stability is a central problem in molecular biology and protein engineering. Recent structure-based deep learning methods, particularly 3D convolutional neural networks (3D CNNs), have achieved strong predictive performance by leveraging high-resolution protein structures. However, proteins exist as heterogeneous conformational ensembles rather than single static structures, and the impact of conformational flexibility on structure-based ΔΔG predictors remains poorly characterized. Consequently, current models may yield unstable or even contradictory predictions when evaluated across alternative, yet equally plausible, conformations of the same protein. We introduce OrgNet+, a conformational ensemble-aware and orientation-gnostic framework that explicitly incorporates protein structure flexibility during training. OrgNet+ is trained on augmented datasets comprising diverse conformational ensembles generated using a comprehensive set of molecular modelling methods: normal mode analysis, molecular dynamics, Monte-Carlo simulations, and a generative deep learning model. Across all ensemble types, OrgNet+ substantially reduces intra-ensemble prediction variance while simultaneously improving predictive accuracy. The improved performance extends to standard single-reference-structure benchmarks, even though OrgNet+ was trained exclusively on conformational ensembles and never exposed to the reference experimental structures. OrgNet+ is available at https://github.com/i-Molecule/OrgNet.","42414029":"ID: 42414029\nTitle: Case of concurrent ALS and human T-cell leukaemia virus type 1-associated myositis.\nAbstract: A woman in her late 70s presented with progressive limb weakness, muscle atrophy and hyper-reflexia. Laboratory findings revealed elevated creatine kinase and positive serum human T-cell leukaemia virus type 1 (HTLV-1) antibody. Clinical and electrophysiological findings met revised El Escorial criteria for amyotrophic lateral sclerosis (ALS), but muscle MRI showed inflammatory changes. Muscle biopsy revealed both neurogenic and inflammatory features. While methylprednisolone showed no benefit, intravenous immunoglobulin therapy produced transient improvement in weakness with normalisation of creatine kinase levels. The patient died from respiratory failure 3 years after symptom onset. Autopsy confirmed typical ALS-TDP pathology with phosphorylated TDP-43 inclusions in motor neurons. HTLV-1 Tax-positive lymphocytes infiltrated skeletal muscles but not the central nervous system, establishing dual pathology of ALS-TDP with HTLV-1-associated myositis. The improvement most likely reflected treatment of the HTLV-1-associated myositis rather than the underlying motor neuron disease. This case highlights the importance of evaluating treatable conditions in HTLV-1-seropositive ALS patients.","42414528":"ID: 42414528\nTitle: Annexin A11 and TDP-43: core players in neurodegeneration.\nAbstract: Annexin A11 (ANXA11) is a Ca2⁺-dependent phospholipid-binding protein that has recently emerged as a key player in neurodegeneration. Rare pathogenic ANXA11 variants were initially identified in cases of amyotrophic lateral sclerosis (ALS). Since then, ANXA11 has been linked to a broader spectrum of related neurodegenerative diseases. Two independent studies demonstrated that ANXA11 co-aggregates with TDP-43 in all cases of frontotemporal lobar degeneration with TDP-43 pathology (FTLD-TDP) type C, with cryo-EM revealing heteromeric ANXA11-TDP-43 filaments. These discoveries support the direct pathological interaction between the two proteins as an important feature of FTLD-TDP type C. We also described secondary ANXA11 pathology in related neurodegenerative diseases, including limbic-predominant age-related TDP-43 encephalopathy (LATE), and more rarely in ALS and FTLD-TDP types A and B. ANXA11 and TDP-43 co-aggregates are also a feature of a FTLD-TDP associated with primary lateral sclerosis. These advances have renewed interest in ANXA11 as a major player in ALS/FTLD pathogenesis in both genetic and sporadic neurodegenerative diseases. In this review, we summarize ANXA11 pathology across genetic and sporadic cases, highlighting its heterogeneous overlap with TDP-43 pathology. We synthesize current knowledge of ANXA11's physiological roles in phase separation, membrane repair, and RNA granule dynamics, integrating emerging evidence on how disruption of these processes may promote pathological aggregation and toxicity. Finally, we outline priorities for future research, with particular emphasis on elucidating ANXA11's mechanistic connection to TDP-43.","42414949":"ID: 42414949\nTitle: Biological sex differences in neurodegenerative diseases in Africa: a scoping review of evidence and research gaps.\nAbstract: Biological sex is a well-established determinant of risk, progression, and therapeutic response in neurodegenerative diseases (NDs). However, current evidence on sex differences in NDs is from high-income Western populations. This review aims to map and synthesize evidence on biological sex differences in NDs in Africa, and to identify key research gaps. This scoping review was conducted in accordance with the Joanna Briggs Institute methodology and reported in accordance with the PRISMA-ScR guidelines. A literature search was conducted on PubMed, African Journals Online, Sabinet Journals, ScienceDirect, and Google Scholar. We included studies conducted in African countries that reported sex disaggregated data or examined biological sex differences in at least one ND. Data were synthesized descriptively. All included studies reported sex distribution, but most (about 84%) did so only descriptively. Approximately 17% conducted sex-stratified analyses beyond prevalence. Similar to global epidemiological trends, several studies suggested a higher prevalence or odds of dementia and multiple sclerosis among females, while male predominance was observed in Parkinson's disease and Amyotrophic lateral sclerosis studies. An earlier onset and a higher mutation frequency in LRRK2-G2019S were reported in females with Parkinson's disease in some studies, while another study reported a higher mortality rate in females with dementia. No study evaluated sex specific biomarker profiles, disease progression, or treatment response. Evidence on biological sex differences in NDs in Africa remains limited and is largely descriptive. Mechanistic, longitudinal, and biomarker-based investigations are largely absent.","42417834":"ID: 42417834\nTitle: [Far more than a dress code: more women, new leadership styles : Rethinking leadership in medicine-perspectives of the German Medical Women's Association].\nAbstract: The transformation of the healthcare system requires fundamental rethinking of medical leadership. Despite rising numbers of female physicians in both education and practice, their presence in leadership roles remains significantly underrepresented. This article examines this structural discrepancy from the perspective of the German Medical Women's Association (DÄB). It argues that gender equality is not merely a question of fairness, but a decisive factor for the quality, innovation, and sustainability of medical care. Analysis of current literature. Diverse leadership teams make more informed decisions, act with greater resilience, and demonstrably contribute to improved outcomes. Traditional role models, nontransparent selection processes, and inadequate structural conditions often prevent female physicians from gaining equal access to leadership positions. Innovative leadership and working models, such as top-level sharing, tandem structures, and part-time leadership, enhance both work-life balance and the attractiveness of medical careers. Mentoring, transparent career development, and the early promotion of leadership skills also contribute. Participation of patients, interprofessionalism, and digital skills are becoming increasingly important. The DÄB sees these developments as an opportunity to redefine leadership-as cooperative, diverse, and forward-looking. This requires structural reforms that systematically support female physicians and involve them in key decision-making processes.

Er zeigt dabei, dass Geschlechtergerechtigkeit nicht nur eine Frage der Fairness, sondern ein entscheidender Faktor für Qualität, Innovation und Zukunftsfähigkeit der medizinischen Versorgung ist. Aktuelle Literatur wurde ausgewertet. Divers zusammengesetzte Führungsteams treffen fundiertere Entscheidungen, agieren resilienter und tragen nachweislich zu verbesserten Ergebnissen bei. Dennoch verhindern tradierte Rollenbilder, intransparente Auswahlprozesse sowie strukturelle Rahmenbedingungen oftmals den gleichberechtigten Zugang von Ärztinnen zu Führungspositionen. Innovative Führungs- und Arbeitsmodelle, wie z. B.

The most common genetic cause of ALS in both familial and sporadic cases is the expansion of a hexanucleotide repeat in the C9orf72 gene. To systemically dissect the molecular landscape of ALS, we performed integrative transcriptomic analyses across multiple central nervous system regions from ALS patients carrying pathological C9orf72 repeat expansions (ALS-C9) and those without the mutation (ALS-non-C9). In parallel, we performed transcriptome-wide cell-type deconvolution to assess the cellular composition of neuronal and non-neuronal populations. We identified a set of dysregulated molecular pathways that were consistently altered in both ALS-C9 and ALS-non-C9 patients, suggesting shared pathogenic mechanisms. Distinct gene-specific alterations also pointed to divergent subtype-dependent molecular trajectories. Gene-specific alterations were also associated with short clinical duration in ALS-non-C9, highlighting a sex-dependent immunological contribution to disease outcome. Our cross-regional integrative transcriptomic analyses reveal both convergent and divergent molecular and cellular features between ALS-C9 and ALS-non-C9 subgroups, underscoring the clinical heterogeneity of ALS and providing a framework for subtype- and sex-specific therapeutic stratifications.","42420060":"ID: 42420060\nTitle: Development of a target product profile for artificial intelligence in diabetic eye screening in England: a modified Delphi consensus study.\nAbstract: Artificial intelligence (AI) health-care technologies offer a means of addressing the growing gap between health-care capacity and demand. However, few technologies have met the complex requirements of health-care systems for adoption. Diabetic eye screening (DES) in England exemplifies the difficulty of understanding these requirements and translating them into real-world implementation decisions. This Review responds to a recognised policy need to develop a target product profile (TPP) for a DES AI system for use in England. The TPP outlines the requirements of the English health-care system for such a device and was developed using a modified Delphi consensus process involving interviews, surveys, and a consensus meeting. Participants included people living with diabetes, health-care professionals, health-care managers and leaders, regulators and policy makers, and developers. Thirty-five product specifications were agreed upon, covering areas such as clinical validity, utility, and environmental sustainability. Our TPP establishes clear criteria for DES AI development and deployment in England, and this TPP development process can serve as a template for initiatives to create TPPs for other AI health technologies and settings.","42420185":"ID: 42420185\nTitle: Neuronal Intranuclear Inclusion Disease Mimicking Familial ALS: A Multigenerational Case Series With Diagnostic Pitfalls.\nAbstract: ","42420559":"ID: 42420559\nTitle: Microglial TDP-43 mediates myelin refinement and represses Tyrobp cryptic exon inclusion in mice.\nAbstract: TDP-43 proteinopathy is a hallmark of neurodegenerative disorders such as amyotrophic lateral sclerosis and frontotemporal dementia where mislocalization of TDP-43 has been observed in neurons and glial cells. However, the role of TDP-43 in microglia and the consequences of its loss of function remain unexplored. Combining magnetic resonance imaging, and confocal, and electron microscopy, we uncovered structural changes and myelin abnormalities in the early postnatal brain of mice lacking microglial TDP-43. Spatial transcriptomics further revealed an enriched interferon-responsive signature associated with oligodendrocyte dysfunction. Early depletion of microglial TDP-43 led to motor deficits in adult mice. Mechanistically, knocking out TDP-43 impaired microglial ability to engulf and degrade myelin. It also led to cryptic exon inclusion in the Tyrobp mRNA, resulting in truncated DAP12 protein, thus causing defective TREM2 signaling. Our findings reveal a role for TDP-43 in regulating the TREM2-DAP12 axis in mice, highlighting a previously unrecognized mechanism through which TDP-43 controls microglial function.","42421532":"ID: 42421532\nTitle: Accelerating reaction kinetics of AlCl3/acetamide electrolyte by co-solvation for Al-S batteries.\nAbstract: Deep eutectic solvents such as AlCl3/acetamide (AcA) have demonstrated great potential as room-temperature electrolytes for Al-S batteries, but their high viscosities and low ionic conductivities severely impede the electrochemical reaction kinetics. Herein, we report an effective strategy to optimize AlCl3/AcA by screening fluorobenzene co-solvents. The optimal 1,2,3-trifluorobenzene (tFBn) effectively dilutes AlCl3/AcA and has a crowding effect that creates a local high-concentration zone for efficient transport of electro-active ions. Rather than merely functioning as a diluent, tFBn induces the localized aggregation of neutral molecules and ion clusters, which reduces the bulk viscosity by 50% and doubles the ionic conductivity. This localized high concentration, coupled with the rapid migration of ion clusters, accelerates the reaction kinetics and improves the long-cycling stability of Al stripping/plating. tFBn also promotes the transportation of Al-Cl species onto Al to regulate the interphase structures and reduce the resistance. Due to the accelerated reaction kinetics, the tFBn-modified AlCl3/AcA further improves the S utilization, reduces the polarization, and enhances the capacity retention of Al-S batteries. This study provides important insights into the design of high-performance electrolytes toward practical Al-S batteries.","42422319":"ID: 42422319\nTitle: Smoking and the risk of neurodegenerative diseases in a Chinese case-control study.\nAbstract: While smoking is inversely associated with Parkinson's disease (PD) risk, its relationship with amyotrophic lateral sclerosis (ALS) and multiple system atrophy (MSA) remains unclear, particularly in Asian populations. We investigated these associations in a Chinese case-control study. We recruited newly diagnosed ALS (n=430), MSA (n=271), PD (n=523) cases and hospital-based controls (n=1033) in Sichuan, China. Logistic regression models were used to evaluate associations between smoking and disease risks, adjusting for demographic, lifestyle and occupational factors. Compared with never-smokers, the adjusted ORs and 95% CIs of ALS for current and former smokers were 1.00 (0.61 to 1.65) and 1.79 (1.01 to 3.17), respectively. For MSA, ORs were 1.27 (0.73 to 2.23) for current smokers and 2.54 (1.41 to 4.60) for former smokers. Individuals who quit within 4 years before diagnosis showed the highest risk of ALS (OR=1.93, 95% CI 0.96 to 3.88) and MSA (OR=2.09, 95% CI 1.11 to 3.93). For both ALS and MSA, no consistent trend was found with increasing smoking duration or pack-years. In contrast, ever-smokers had a significantly lower PD risk (OR=0.49, 95% CI 0.33 to 0.71), particularly current smokers (OR=0.30, 95% CI 0.19 to 0.48). Longer smoking duration and higher cumulative smoking were also linked to PD risk with clear negative exposure-response patterns (P trend=0.039 and 0.029, respectively). Consistent with findings in non-Asian populations, smoking was inversely associated with PD risks in the Chinese population. For ALS and MSA, we found evidence suggestive of positive relationships with cigarette smoking, but no clear exposure-response relationships were observed.","42422903":"ID: 42422903\nTitle: Spectroscopic discrimination of bacterial species of variable pathogenicity through explainable machine learning.\nAbstract: Rapid and accurate identification of bacterial pathogens and their degree of pathogenicity is essential for guiding antimicrobial therapy. Current culture-based methods require a timeframe of at least 24-48 h for species-level identification alone, which often leads to substantial disease progression and increases the propensity of antimicrobial resistance (AMR). Surface-Enhanced Raman Spectroscopy (SERS) shows promise in mitigating these drawbacks by providing a fast, non-invasive, label-free method to capture the biochemical fingerprints of bacteria achievable under clinical settings. However, the molecular complexity of SERS spectra, which has been an impediment for conventional data analysis, demands robust computational frameworks for reliable species-level identification. Here, we employ a comprehensive SERS analysis scheme with supervised machine learning and explainable artificial intelligence (XAI) to discriminate five clinically relevant pathogens, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, methicillin-resistant S. aureus (MRSA), and Enterococcus faecalis, and to probe their degree of pathogenicity from a biomarker perspective. Among the tested models - Support Vector Machine (SVM), k-Nearest Neighbour (kNN), Random Forest (RF), and a 1D Convolutional Neural Network (CNN) - CNN achieved near-perfect classification accuracy, capturing subtle and spectrally relevant variations often inaccessible to traditional algorithms. Notably, the 1D-CNN also achieved 100% discrimination between MRSA and methicillin-sensitive S. aureus - two strains of the same species differing only in resistance phenotype. To ensure transparent decision-making and eliminate the black-box nature of machine learning models, SHapley Additive exPlanations (SHAP) analysis was applied to both RF and CNN models, which facilitated the convergence of both frameworks on the same discriminatory Raman regions, revealing conserved biochemical determinants of species identity. Complementary MCR-ALS decomposition further resolved the spectra into interpretable biochemical components and provided the rubric for biochemical differentiation. Together, this study aims to demonstrate an end-to-end explainable workflow that couples SERS with interpretable AI, offering a rapid, transparent approach for pathogenic disease diagnosis.","42423631":"ID: 42423631\nTitle: Identifying Gastrostomy Care and Home Gastrostomy Tube Feeding-Related Educational Content for Patients With Amyotrophic Lateral Sclerosis and Their Family Caregivers: A Delphi Panel With Professional Stakeholders.\nAbstract: Enteral nutrition is delivered through a gastrostomy tube to provide nutritional support to patients with amyotrophic lateral sclerosis (ALS) who have developed severe dysphagia at home. Complications may arise from gastrostomy and enteral nutrition when family caregivers do not provide adequate care. This study identifies key areas of educational content that can improve the care of patients with ALS requiring gastrostomy and home enteral nutrition. We conducted a modified three-round e-Delphi survey with health care experts to clarify their perspectives on the educational content regarding gastrostomy and home enteral nutrition disseminated among patients with ALS and their family caregivers. The experts provided their opinions on specific educational content areas, and their responses were analyzed to identify areas of consensus and divergence. Accordingly, in Rounds 1-3 of the survey, 16 experts, including registered nurses (n = 6), advanced practice registered nurses (n = 3), clinical neurologists (n = 3), and dieticians (n = 4), participated. In Round 3, four categories and 39 educational components reached consensus. The results provide a framework for developing educational nursing interventions for family caregivers of patients with ALS receiving home enteral nutrition through gastrostomy tubes and for defining the essential elements of the educational content of such interventions.","42424231":"ID: 42424231\nTitle: Neurofilament Light Chain as a Biomarker in Neurology.\nAbstract: Neurofilament light chain (NfL) has emerged as a highly sensitive biomarker of neuroaxonal injury across diverse neurological disorders. This review synthesizes current evidence regarding its diagnostic, prognostic, and therapeutic-monitoring utility, while outlining major clinical limitations and emphasizing the complementary role of glial fibrillary acidic protein (GFAP). NfL concentrations increase following axonal damage and correlate with inflammatory activity, lesion burden, and long-term disability progression in multiple sclerosis. Elevated levels also reflect neurodegeneration in Alzheimer's disease, predict disease severity and survival in amyotrophic lateral sclerosis, and are associated with motor and cognitive decline in Parkinson's disease and multiple system atrophy. In acute neurological conditions, including traumatic brain injury and stroke, NfL serves as a robust indicator of the extent of neuronal injury. Interpretation is constrained, however, by substantial physiological variability related to age, renal function, body mass index, and comorbidities, limiting the utility of absolute cut-off values. GFAP provides complementary information by capturing astrocytic damage, and the GFAP/NfL ratio may aid in differentiating multiple sclerosis from neuromyelitis optica spectrum disorder. Integration of NfL with multimodal biomarkers- such as GFAP, tau proteins, proteomic and metabolomic signatures, and advanced neuroimaging-may enhance diagnostic specificity and prognostic accuracy. Future research priorities include establishing age-adjusted reference intervals, validating longitudinal thresholds, and incorporating NfL into therapeutic monitoring frameworks. Advances in these areas are expected to improve diagnostic precision and support broader clinical implementation of NfL.","42424572":"ID: 42424572\nTitle: Comprehensive Care Goals in Myasthenia Gravis: Expert Consensus Recommendations Using the RAND/UCLA Appropriateness Method.\nAbstract: Goals for comprehensive care are important in the management of individualized treatment for patients with myasthenia gravis (MG), a disease with variable presentation and degrees of severity. Yet there is limited guidance on how comprehensive care should be achieved and implemented. We present global consensus recommendations for comprehensive care of patients with MG. An international panel of experts was formed, and a targeted literature review was conducted to inform the recommendations. A steering committee selected relevant topics and draft recommendations were developed for each topic. Formal consensus was achieved using the RAND/UCLA appropriateness method. Seventeen panelists from North America, Europe, and Asia rated statements online from 1 (\"extremely inappropriate\") to 9 (\"extremely appropriate\") and provided comments and suggestions for modifications. The methodologist modified statements for further rating, based on panel scores and feedback. Statements achieving agreement as appropriate by 4 rounds of rating were accepted. Consensus was achieved for 21 statements. Statement 1 defined the ongoing treatment goal: \"to work toward, achieve, and sustain minimal symptoms and treatment-related adverse events, with a patient-acceptable quality of life (using validated measures)\". Subsequent statements described implementation of this goal and covered: early control of symptoms; establishing and sustaining a treatment goal; vaccination and screening for infection; family planning/pregnancy; management of fatigue and comorbidities; and management of impending crisis and crisis. Expert consensus was achieved on a series of global recommendations for comprehensive care goals, which has implications for improved disease outcomes and health-related quality of life for patients with MG. These recommendations will require updating as treatment paradigms evolve.","42425084":"ID: 42425084\nTitle: RNA-dependent SFPQ condensates coordinate multidimensional regulation of extra-long neuronal genes.\nAbstract: The mammalian brain uniquely expresses a large repertoire of extra-long genes critical for neuronal development and function, yet these transcripts are particularly vulnerable to dysregulation linked to neurological disorders, such as autism spectrum disorder and amyotrophic lateral sclerosis. The molecular mechanisms that ensure their stable expression remain poorly understood. Here, we show that the RNA-binding protein SFPQ forms meshwork-like biomolecular condensates that scaffold a multidimensional gene regulatory complex essential for long-gene expression. Super-resolution microscopy and functional perturbation assays demonstrate that disruption of SFPQ condensates impairs both extra-long gene expression and splicing. Proximity-dependent biotin labeling combined with mass spectrometry (BioID-MS) reveals that SFPQ condensates recruit transcriptional elongation factors, splicing regulators, and chromatin remodelers. Notably, many of these interactors overlap with autism-associated genes, suggesting direct disease relevance. These findings define a higher-order nuclear architecture organized by SFPQ and provide mechanistic insight into long-gene transcriptopathies underlying neurological disorders.","42425146":"ID: 42425146\nTitle: Contrast-Enhanced Ultrasound versus Contrast-Enhanced Computed Tomography in the Detection of Renal and Splenic Infarctions.\nAbstract: Intra-abdominal organ infarctions require prompt imaging for diagnosis. Contrast-enhanced computed tomography (CECT) is considered the gold standard but involves radiation, iodinated contrast, and logistical challenges in critically ill patients. Contrast-enhanced ultrasound (CEUS) enables real-time assessment of microvascular perfusion without ionizing radiation. The aim of this study was to evaluate the diagnostic performance of CEUS compared to CECT for detecting intra-abdominal organ infarctions. This retrospective observational study included patients treated at a tertiary care center (2010-2024) who underwent both CEUS and CECT for suspected intra-abdominal organ infarction. With CECT as reference standard, diagnostic performance parameters and agreement (Cohen's kappa) were calculated. 24 patients (median age 60 years; 12 female) were included. CECT confirmed organ infarction in 16/24 patients (66.7%). CEUS correctly identified 15 of these cases (Sensitivity 93.8%; 95% confidence interval [CI]: 71.7-98.9%). Specificity was 75.0% (95% CI: 40.9-92.9%), with two false-positive CEUS findings. Positive and negative predictive values were 88.2% (95% CI: 65.7- 96.7%) and 85.7% (95% CI: 48.7-97.4%), respectively. Agreement of CECT and CEUS was substantial (Cohen's κ = 0.71). Wedge-shaped perfusion defects were identified in 93.8% of CT-confirmed infarctions on both modalities. CEUS demonstrates high sensitivity and good agreement with CECT for the detection of intra-abdominal organ infarctions. CEUS represents a valuable imaging modality, particularly when CECT is contraindicated or not available. Prospective studies are warranted to further define its role in clinical practice. Zielsetzung: Intraabdominelle Organinfarkte erfordern eine rasche bildgebende Diagnostik. Die kontrastmittelverstärkte Computertomographie (CECT) gilt als Goldstandard, ist jedoch mit Strahlenexposition, jodhaltigen Kontrastmitteln sowie logistischen Herausforderungen bei kritisch kranken Patienten verbunden. Der kontrastmittelverstärkte Ultraschall (CEUS) ermöglicht eine Echtzeitbeurteilung der Perfusion ohne ionisierende Strahlung. Ziel dieser Studie war die Evaluation der diagnostischen Leistungsfähigkeit der CEUS zur Detektion intraabdomineller Organinfarkte im Vergleich zur CECT. In diese retrospektive Beobachtungsstudie (2010-2024) wurden Patientinnen und Patienten an einem tertiären Versorgungszentrum eingeschlossen, bei denen sowohl eine CEUS- als auch eine CECT-Untersuchung bei Verdacht auf intraabdominelle Organinfarkte durchgeführt wurde. Mit der CECT als Referenzstandard wurden die diagnostischen Testparameter und Übereinstimmung (Cohen's kappa) berechnet. Ergebnisse: 24 Patientinnen und Patienten wurden eingeschlossen (Medianalter 60 Jahre; 12 weiblich). Die CECT bestätigte in 16/24 Fällen (66,7%) einen Organinfarkt. Der CEUS identifizierte 15 Fälle korrekt (Sensitivität 93,8%, 95% Konfidenzintervall [KI]: 71,7-98,9%). Die Spezifität betrug 75,0% (95% KI: 40,9-92,9%) bei zwei falsch-positiven CEUS-Befunden. Der positive und negative prädiktive Wert betrugen 88,2% (95% KI: 65,7- 96,7%) respektive 85,7% (95% CI: 48,7-97,4%). Die Übereinstimmung zwischen CECT und CEUS war substantiell (Cohen's κ = 0,71). Keilförmige Perfusionsdefekte wurden in 93,8% der bestätigten Infarkte in beiden Modalitäten identifiziert. Schlussfolgerung: Der CEUS zeigt eine hohe Sensitivität und eine gute Übereinstimmung mit der CECT bei der Detektion intraabdomineller Organinfarkte. Der CEUS stellt für diese Fragestellung eine wertvolle Bildgebungsmodalität dar, insbesondere wenn CECT kontraindiziert oder nicht verfügbar ist. Prospektive Studien sind erforderlich, um seine Rolle in der klinischen Praxis weiter zu definieren.","42425169":"ID: 42425169\nTitle: Sex-associated neuroinflammatory and astrocytic responses in amyotrophic lateral sclerosis: evidence from clinical cohorts and a TDP-43 N390D mouse model.\nAbstract: Sex differences are increasingly recognized as important modifiers of neuroimmune processes in neurodegenerative disorders. However, the sex-associated clinical phenotypes and underlying neuroinflammatory mechanisms in amyotrophic lateral sclerosis (ALS) remain poorly understood. This study integrated multimodal clinical assessments, cerebrospinal fluid (CSF) neuroimmune biomarkers, neuroimaging-based glymphatic metrics, and complementary animal analyses to characterize shared and sex-associated alterations in male and female ALS patients. Two independent cohorts including 158 newly diagnosed ALS patients and 112 healthy controls (HCs) underwent evaluations of motor function, cognition, sleep disturbances, and emotional symptoms. Glymphatic function was assessed using choroid plexus volume (CPV), diffusion-derived analysis along the perivascular space (ALPS) index, and white-matter free-water (FW) fraction. In the original cohort, 12 CSF biomarkers spanning astrocytic activation, neuroinflammation, TDP-43 pathology, synaptic dysfunction, and axonal injury were quantified, and glial fibrillary acidic protein (GFAP), interleukin-6 (IL-6), and interleukin-18 (IL-18) were further examined in an independent verification cohort. Complementary neuroimmune alterations were further examined in TDP-43 N390D knock-in mice using ELISA and immunofluorescence. Male ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q < 0.05). Female ALS patients exhibited increased CSF IL-6 versus HCs, whereas GFAP and IL-18 levels were unchanged. Female ALS patients also demonstrated more severe depressive symptoms and post-traumatic stress disorder than male ALS patients and HCs (p < 0.05). Both sexes displayed glymphatic impairment characterized by increased CPV and FW and reduced ALPS index, as well as pronounced sleep disturbances relative to HCs (all p < 0.05), with no clear sex-related differences. Complementary animal data showed that, at a fixed chronological age, male TDP-43 N390D mice exhibited more severe motor impairment accompanied by higher brain levels of GFAP, IL-6, and IL-18 and more prominent astrocyte-associated IL-6 and IL-18 signals than female mutant mice. Although microglial activation was also observed in TDP-43 N390D mice, no clear sex-related difference was detected at the sampled age. This multimodal clinical-translational study reveals sex-associated neuroinflammatory heterogeneity in ALS. Male patients exhibit a more pronounced GFAP-, IL-6-, and IL-18-related inflammatory profile, whereas female patients display more prominent affective disturbances. Glymphatic dysfunction and sleep impairment emerge as common pathological pathways across sexes. These findings highlight sex as a crucial biological variable shaping ALS heterogeneity and underscore the importance of incorporating sex-stratified analyses in future ALS neuroimmune research and clinical trials.","42425598":"ID: 42425598\nTitle: Unusual presentation of amyotrophic lateral sclerosis years after a motor-vehicle collision.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare disease caused by the destruction of motor neurons, typically presenting with unilateral lower motor neuron and upper motor neuron symptoms. Here, we report the case of a female in her mid-60s with a complex history of lower extremity weakness following a motor-vehicle collision 3 years before her current presentation with a subacute complaint of right-sided leg weakness. With an atypical symptom course consisting of resolved and recurrent weakness of her left leg, the patient had multi-level chronic, evolving spinal-column damage, severe weight loss, newly discovered rectal neoplasm and longstanding psychiatric pathology. With symptoms concerning for both medical and psychosomatic explanations, several potentially compounded aetiologies were considered. Here, we discuss important considerations for fluctuating chronic and subacute neurological complaints with a broad differential diagnostic spectrum and how a macro-perspective of symptoms over years can aid in the diagnosis of a challenging ALS presentation.","42426148":"ID: 42426148\nTitle: Multitarget therapeutic potential of sulforaphane in ethidium bromide-induced neurotoxicity in multiple sclerosis-like pathology: comparison with omaveloxolone and dimethyl fumarate on neuroprotection and systemic recovery.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by demyelination, neuroinflammation, and neurodegeneration. This study investigates the neuroprotective potential of Sulforaphane (SFN) in ameliorating ethidium bromide (EBRM)-induced MS-like pathology in Wistar rats. The efficacy of SFN at two doses (SFN1.5 and SFN3) was compared to FDA-approved Nrf2 activator drugs, omaveloxolone (OMV15) and dimethyl fumarate (DIMF50). EBRM administration caused neurobehavioral deficits, demyelination, oxidative stress, axonal degeneration, and inflammation. It disrupted key cellular pathways, including Nrf2/HO-1/SIRT-1, JAK/STAT-3/mTOR, and BACE-1/Gamma-secretase/MAPT, as well as caused neurotransmitter imbalances. SFN3 demonstrated significant improvement in motor function, cognitive performance, neurotransmitter levels antioxidant enzymes and alleviated neuroinflammation by modulating inflammatory cytokines. Molecular analyses showed that SFN3 increased Nrf2/HO-1/SIRT-1 levels while decreased pro-inflammatory and neurodegenerative markers such as STAT-3, mTOR, and BACE-1 levels. Gross pathological, Histopathological, and LFB studies indicated reduced demyelination and liver damage. SFN3 also demonstrated favourable systemic safety compared to OMV15. While DIMF50 showed the highest overall efficacy, SFN3 showed consistent modulation of pathological markers, neuroprotective effects, and safety profile. These findings suggest that SFN3 may have therapeutic potential for further translational research in MS. Future studies should validate its clinical relevance and explore combinatorial therapies with existing MS treatments to enhance therapeutic outcomes.","42426288":"ID: 42426288\nTitle: The emerging role of circular RNAs in neurodegenerative diseases and viral infections.\nAbstract: Circular RNAs (circRNAs) represent a class of highly stable, covalently closed RNA molecules increasingly recognized as important regulators of brain aging and neurodegenerative disease. Growing evidence also implies circRNAs in viral infection, suggesting a potential intersection between viral neuropathogenesis and neurodegeneration. However, no studies have yet directly integrated circRNAs, neurotropic viral infections, and neurodegenerative disorders within a single mechanistic framework. To date, specific circRNAs have been linked to the progression of Alzheimer's disease and Parkinson's disease, where they regulate central pathological processes including amyloid-β clearance, neuroinflammation, synaptic plasticity, neuronal apoptosis, and oxidative stress. Moreover, it has been established that both host cells and viruses produce circRNAs during infection. Virus-derived circRNAs can enhance viral replication, promote immune evasion, and support latency. In contrast, host circRNAs contribute to antiviral defense by acting as microRNA sponges, interacting with viral proteins, or encoding peptides with antiviral activity, mechanisms particularly explored in viral oncogenesis. In this review, we will evaluate the most updated research evidence on the role of circRNAs in major neurodegenerative diseases and neurotropic viral infections. Considering the growing concern regarding the long-term neurological consequences of viral infections, including chronic neuroinflammation, viral reactivation, and post-viral syndromes, dysregulated circRNAs may represent a mechanistic link between viral infection and associated neurodegenerative processes. Finally, we will discuss future directions for identifying circRNAs-based biomarkers and developing circRNAs-targeted therapeutic strategies for age-related and virus-associated neurological disorders.","42426293":"ID: 42426293\nTitle: Glial Cysteine Cathepsins: From Homeostasis to Neurodegeneration.\nAbstract: Glial cells, namely microglia, astrocytes, and oligodendrocytes, play crucial roles in maintaining homeostasis in the central nervous system and orchestrating responses to injury, infection, and disease. Among the molecular regulators of glial function, cysteine cathepsins have emerged as key modulators of both physiological and pathological processes. These lysosomal peptidases are traditionally known for their housekeeping roles in protein degradation; however, accumulating evidence highlights their broader involvement in antigen presentation, microglial and astrocyte reactivity, inflammatory signalling, apoptosis, and myelination. Under normal conditions, cysteine cathepsins support essential functions in the central nervous system, including immune surveillance and tissue remodelling. Conversely, their dysregulation, characterized by overexpression, increased enzymatic activity, or mislocalization, can promote neuroinflammation and neurodegeneration, contributing to the pathogenesis of disorders such as Alzheimer's disease and multiple sclerosis. This review provides a comprehensive synthesis specifically focused on the diverse roles of cysteine cathepsins across major glial cell types, systematically summarizing current knowledge in microglia, astrocytes, and oligodendrocytes. We emphasize their cell type-specific, context-dependent, protective, and deleterious functions. Furthermore, we discuss mechanistic links between cysteine cathepsin activity and neurodegenerative processes and evaluate the therapeutic potential and current limitations of selectively targeting glial cysteine cathepsins. A deeper understanding of the context-dependent dual roles of these enzymes in brain physiology and pathology is critical for designing targeted interventions that could mitigate neuroinflammation and neurodegeneration.","42426383":"ID: 42426383\nTitle: Immune Activation and Glial Dysfunction in Spinocerebellar Ataxias: From Cerebellar Landscape to Disease-Driven Mechanisms and Immunomodulation.\nAbstract: Spinocerebellar ataxias (SCAs) comprise a clinically and genetically heterogeneous group of autosomal dominant neurodegenerative disorders. Despite the recognized role of specialized cerebellar glia in cerebellar development and dysfunction, immune activation and non-immune glial responses remain understudied in SCAs. This narrative review compiles evidence from cellular, animal, and human models on the cerebellar immune landscape and the specific pathways that drive homeostatic failure and neuroinflammatory cascades across SCA subtypes. Microgliosis emerges consistently-and often early- as a generalized feature across the SCA spectrum, preceding neurodegeneration in several subtypes. Concurrently, reactive astrogliosis extends broadly, reflecting widespread macroglial surveillance and metabolic stress regulation throughout histologically preserved gray matter, with specialized homeostatic failure of Bergmann glia in SCA1, SCA2, and SCA7. Peripheral inflammation, manifests as early as the prodromal stage and correlates with the cognitive-affective deficits in SCA2 and associates with the mutation size in SCA3, positioning it as integral to pathogenesis rather than epiphenomenal. Diverse, partially shared signaling pathways converge on multi-lineage glial breakdown and reciprocal neuroimmune crosstalk. These mechanisms involve NF-κB (SCA1,3,17), cGAS-STING (SCA2), TLR/MyD88 (SCA6), and JNK/c-Jun (SCA1,2,7). This review establishes abnormal reciprocal immune/non-immune glia crosstalk as a core pathogenic principle across SCAs, revealing novel therapeutic opportunities. In fact, targeting convergent signaling nodes such as NF-κB, or JNK pathways, holds disease-modifying potential across multiple subtypes. Future research should prioritize standardized comparative studies, longitudinal analyses linking both inflammation and non-immune glial pathology to clinical progression, and clinical trials evaluating targeted immunomodulatory and glial homeostatic-supportive agents.","42426471":"ID: 42426471\nTitle: Cutaneous silent period in patients with obstructive sleep apnea.\nAbstract: Empirical evidence suggests that the duration of the Cutaneous Silent Period (CuSP) is significantly extended in pathological states such as Idiopathic Parkinson's Disease (IPD), Restless Legs Syndrome (RLS), and dystonia, all of which are correlated with the degeneration of dopaminergic neurons. This neurodegenerative process is a critical factor in the etiology of Obstructive Sleep Apnea (OSA). In light of this active participation, the present study sought to assess the CuSP in patients with OSA. A cohort comprising forty individuals diagnosed with OSA and forty healthy controls, all of whom underwent polysomnographic assessments, was incorporated into this investigation. The study meticulously analyzed the onset time, termination time, and duration of the CuSP in both median nerves utilizing electromyographic techniques. In the study examining the median nerve CuSP study, right and left CuSP was significantly prolonged in patients with OSA (p = 0.001, p < 0.001). Additionally, the onset time of the right and left CuSP was found to be shorter in the patient group (p = 0.017, p = 0.003). The findings indicate that the duration of the CuSP is significantly prolonged in patients with OSA, similar to observations in IPD, RLS and dystonia. These results highlight the potential clinical relevance of CuSP duration as a biomarker for OSA-related neuronal alterations.","42426879":"ID: 42426879\nTitle: Evaluating the impact of implementing an ECPR protocol on prehospital resuscitation quality: a randomized controlled simulation study.\nAbstract: Extracorporeal Cardiopulmonary Resuscitation (ECPR) is increasingly considered for prehospital cardiac arrest management; however, its impact on resuscitation performance remains unclear. This study aimed to determine whether integrating an ECPR protocol into prehospital cardiac arrest care affects the quality of resuscitation compared to application of the standard Advanced Life Support (ALS) protocol. A randomized controlled simulation study was conducted at the University Hospital Leuven in Belgium using standardized pre-hospital cardiac arrest scenarios. Participants, who were physicians functioning as part of resuscitation teams, were randomized into intervention and control groups. The study included a pre- and post-intervention phase. In the pre-phase, all participants followed the standard ALS protocol. Only the intervention group received training in the additional ECPR protocol between the phases. In the post-phase, the intervention group combined this protocol with standard ALS, whereas the control group continued with ALS alone. The primary outcome was overall resuscitation quality, which was assessed using the modified Peltonen score. The secondary outcomes included occurrence and timing of critical resuscitation actions. A total of 40 physicians participated in the study. Resuscitation quality was not affected by the ECPR protocol; the modified Peltonen score showed no difference in the pre-post change between the groups (0.02, CI: -0.15; 0.19, p = 0.83). However, secondary outcomes showed delayed actions related to the identification and management of the presumed cause of cardiac arrest in the intervention group, such as significantly later verbal suggestions to initiate causal treatments including PCI or thrombolysis. In this simulation study, combining a prehospital ECPR protocol with standard ALS resulted in resuscitation performance comparable to ALS alone.

Protein kinase CK2 is a holoenzyme composed of two regulatory (CK2β) and two catalytic subunits (CK2α and CK2α') and has been linked to multiple aspects of tau pathology. However, genetic evidence defining the specific contributions of CK2 subunits to tau phosphorylation and tauopathy remains lacking. Elucidating subunit-specific roles is critical for the rational development of CK2-targeted therapies. To investigate the impact of CK2 in tauopathy, Neuro-2a and primary cell cultures expressing mutant tau were treated with siRNAs targeting the two catalytic subunits of CK2, CK2α and CK2α'. In addition, the PS19 mouse model of tauopathy was bred to be haploinsufficient for the catalytic subunit CK2α'. Changes in pathology and symptomatology were analyzed via immunohistochemistry, immunoblotting, RNA-sequencing, in situ hybridization, electrophysiology, and Barnes Maze. We found that the expression of the catalytic subunit CK2α', but not catalytic CK2α or regulatory CK2β subunits, was elevated in postmortem brains of dementia patients and in the hippocampus of PS19 tauopathy mice, especially in neurons and microglia. Using a haploinsufficient model of CK2α' in PS19 mice, we demonstrated that the PS19:CK2α'(+/-) mice had significantly decreased phosphorylated tau and total tau burden in the hippocampus and cortex. CK2α' depletion also attenuated microglial activation, pro-inflammatory cytokine production and microglia synaptic engulfment, and enhanced synaptic gene expression, synaptic density, and long-term potentiation. Importantly, CK2α' haploinsufficiency rescued cognitive deficits assessed in the Barnes maze. Here, we show CK2α', one of the two catalytic subunits of CK2, as a novel regulator of tau-mediated neurodegeneration. These effects appear to be mediated through both neuronal and glial functions and may involve CK2α'-dependent modulation of tau phosphorylation as well as neuroinflammatory and immune signaling pathways. These findings identify CK2α' as a mechanistically defined and potentially druggable target for therapeutic strategies aimed at modifying tau-driven neurodegeneration.","42426931":"ID: 42426931\nTitle: Transcriptomic Evidence of Mitochondrial Double-Stranded RNA Accumulation in Brain Aging and Alzheimer's Disease.\nAbstract: Mitochondria and inflammation are tightly linked in aging and Alzheimer's disease (AD), and recent evidence implicates mitochondrial double-stranded RNA (mt-dsRNA) as a potential trigger of inflammation. We examined mt-dsRNA accumulation and dsRNA signaling in brain aging and AD using complementary human brain tissue and in vitro transcriptomic datasets by quantifying mitochondrial transcripts, dsRNA editing, and related gene expression patterns. We found that mt-dsRNA signatures increased after midlife and coincided with reduced expression of mitochondrial RNA processing and translation machinery, along with increased expression of dsRNA antiviral signaling proteins, consistent with cytoplasmic mt-dsRNA-driven inflammation. In AD brains, mt-dsRNA signatures were further increased and correlated with cognitive impairment, neuropathological severity, and AD risk genotypes. Genes associated with these measures reflected altered ubiquitin-dependent regulation of antiviral signaling, potentially indicating altered sensitivity to mt-dsRNA. Together, these findings highlight mitochondrial RNA homeostasis as an unrecognized contributor to age- and AD-related neurodegeneration and identify mt-dsRNA as a potential driver of chronic inflammation in the brain.","42427030":"ID: 42427030\nTitle: C9orf72-associated poly-GR in skeletal muscle leads to neuromuscular junction deficits and muscle atrophy.\nAbstract: Hexanucleotide repeat expansions in C9orf72 produce dipeptide repeat (DPR) proteins that are widely expressed, including the nervous system and skeletal muscle. Among these DPRs, arginine-containing proteins, poly-GR and poly-PR are toxic in the nervous system, but whether DPRs in skeletal muscle contribute to ALS pathogenesis is unclear. Here, we show that muscle-restricted expression of poly-GR drives motor deficits in mice, including muscle atrophy and neuromuscular junction (NMJ) deficits. Poly-GR in muscle interacted with the NMJ key organizer MuSK and promoted MuSK degradation, disrupting postsynaptic structure and impairing neuromuscular transmission. Importantly, a MuSK agonist antibody (X-17) stabilized NMJs and rescued neuromuscular transmission. Moreover, poly-GR in muscle activated the integrated stress response (ISR), elevating eIF2α phosphorylation and broadly suppressing protein translation. ISR inhibition with ISRIB restored translation and MuSK protein levels, and ameliorated both muscle atrophy and NMJ deficits. These findings demonstrate that skeletal muscle actively contributes to C9orf72-ALS pathology. Targeting muscle with ISRIB offers a therapeutic strategy to preserve motor function in C9orf72-ALS.","42427054":"ID: 42427054\nTitle: Youthful-state extracellular vesicles for targeted therapy of intervertebral disc degeneration: resolving inflammation and pyroptosis through NF-κB suppression and NLRP1 inactivation.\nAbstract: Intervertebral disc degeneration pathogenesis involves chronic inflammation and cell death, highlighting the need for targeted therapeutic strategies. Extracellular vesicles (EVs) have emerged as promising bioactive materials for designing therapeutic approach. In this study, we demonstrate that youthful-state EVs (Y-EVs) outperform aged donor-derived EVs (O-EVs) in resolving inflammatory cascades within nucleus pulposus (NP) cells. EVs from young rats significantly suppressed TNF-α-induced inflammation in NP cells by reducing pro-inflammatory cytokine secretion, inhibiting extracellular matrix catabolism, and ameliorating rat disc degenerationin vivo. Mechanistically, CD55 enrichment in Y-EVs attenuated NF-κB pathway activation, thereby disrupting inflammatory transcriptional programs. CD55 knockdown abrogated the anti-inflammatory efficacy of Y-EV, confirming its functional necessity. Besides, we identified thioredoxin (TRX) as a critical suppressor of NLRP1 inflammasome activation via direct protein binding, which inhibited NP cell pyroptosis. Crucially, CD55 in Y-EVs facilitated TRX-mediated NLRP1 suppression, whereas O-EVs failed to upregulate TRX or suppress the NLRP1 inflammasome. This study highlights the age-dependent functional divergence of EV bioactivity and establishes CD55 as a key determinant of their therapeutic superiority. The TRX-NLRP1 interaction represents a novel target for disc degeneration intervention, positioning youthful-state EVs as an optimized bioactive material for disc regeneration strategies.","42427320":"ID: 42427320\nTitle: Frontotemporal Lobar Degeneration-TDP Type C With Striatal Glial Cytoplasmic Inclusions and Motor Neuron Degeneration.\nAbstract: We report an autopsy case of frontotemporal lobar degeneration (FTLD)-TDP type C with severe striatal involvement and annexin A11- and phosphorylated TDP-43-positive glial cytoplasmic inclusions. The patient developed progressive asymmetric rigidity accompanied by marked striatal atrophy and showed both upper and lower motor neuron involvement. These findings expand the clinicopathological spectrum of FTLD-TDP type C and may support the concept of an annexin A11-associated pathogenic continuum linking FTLD and amyotrophic lateral sclerosis.","42427517":"ID: 42427517\nTitle: AART enables fast and accurate cross-platform proteomic translation.\nAbstract: Plasma proteomic profiling has been widely used for biomarker discovery, disease prediction and diagnosis, and patient stratification. However, technical differences across assay platforms often result in low-to-moderate agreement, limiting study reproducibility, data integration, and model transferability. Here we present AART, a cross-platform proteomic translation framework that integrates matched-protein ridge regression with proteome-wide residual learning. We benchmarked AART spanning three independent cohorts profiled using three major platforms, including Olink, SomaScan, and mass spectrometry. Across all six translation directions, AART achieved the best performance compared with baseline methods for both overlapping and non-overlapping protein translations, with a relative improvement of 92.0% on average over direct mapping and by up to 31.6% over cpiVAE, the strongest baseline. Proteins that were accurately translated and improved by AART were enriched for extracellular, vesicle-associated, and tissue-restricted plasma biology. In downstream applications, AART improved the reproducibility of proteomic association analyses relative to direct cross-platform comparison by 75.5% for type 2 diabetes and 370.6% for Alzheimer's disease. AART-enabled cohort integration enhanced diagnostic accuracy for amyotrophic lateral sclerosis by 92.6% compared with non-integration analysis. AART was overall one to three orders of magnitude faster than cpiVAE, facilitating biobank-scale applications. Together, these results establish AART as a fast, accurate, and scalable framework for cross-platform proteomic translation, enabling more reproducible, transferable, and integrated proteomic research.","42427519":"ID: 42427519\nTitle: Humanized tauopathy chimeras uncover microglial and lncRNA strategies for neuroprotection.\nAbstract: Human genetics implicates innate immunity as a key modifier of tau toxicity, yet human-specific neuroimmune mechanisms remain difficult to test in vivo. Here, we developed HuMiNAX, the first humanized iPSC-based neuroimmune xenograft model of tau-associated neurodegeneration, enabling human microglia to interact with human neurons and astrocytes in the adult mouse brain. In HuMiNAX, tau seeding induced aggregation only in mutation-carrying human neural grafts, causing neuron loss and inflammatory activation of human microglia. Progranulin-overexpressing human microglia dampened tau-associated inflammation, preserved neurons, and restored neuronal gene-expression and RNA-splicing programs, supporting microglial control of neuronal resilience. CRISPRi knockdown of the human-specific lncRNA HNRNPK-AS1 also protected neurons in HuMiNAX. These findings establish HuMiNAX as a human neuroimmune model of tauopathy and identify microglial and RNA-mediated strategies of neuronal resilience.","42427539":"ID: 42427539\nTitle: Loss of the lncRNA SOX1-OT promotes p53-dependent cell-cycle arrest in astrocytes.\nAbstract: Long non-coding RNAs (lncRNAs) are increasingly recognized as regulators of brain cell function, but their roles in astrocyte biology and neurodegeneration remain poorly understood. Here, we identify Sox1ot/SOX1-OT as a conserved, brain-enriched lncRNA that is downregulated in Alzheimer's disease and in reactive astrocyte states. Antisense oligonucleotide-mediated depletion of Sox1ot in astrocytes revealed a transcriptional program marked by activation of p53 target genes selectively associated with cell-cycle inhibitory pathways. Consistent with this, Sox1ot depletion enhanced p53 occupancy at target promoters such as Cdkn1a , increased Cdkn1a expression and levels of its protein product p21, and thereby induced G1 arrest and reduced astrocyte proliferation. In contrast, other canonical p53 outputs, including apoptosis and senescence, were not affected, indicating that Sox1ot selectively modulates distinct branches of p53 signaling. Notably, loss of Sox1ot/SOX1-OT was accompanied by impaired glutamate uptake, reduced lactate secretion, and altered astrocyte support functions, suggesting that these deficits arise as downstream consequences of the p53-dependent transcriptional shift rather than direct primary effects of Sox1ot loss. Together, these findings identify SOX1-OT as an astrocyte-enriched regulatory layer that constrains a p53-dependent cell-cycle program and highlight its role in shaping astrocyte state transitions in Alzheimer's disease.","42427540":"ID: 42427540\nTitle: An optimized \"hypoxia in a pill\" regimen reverses neurodegenerative disease phenotypes in multiple preclinical models.\nAbstract: A growing body of pre-clinical research has demonstrated the therapeutic potential of chronic, continuous hypoxia (11% FIO2) for treating both rare and common forms of neurodegeneration (1). However, the chronic delivery of hypoxic gas poses both practical challenges and long-term safety concerns. We previously introduced a small molecule, \"hypoxia-in-a-pill\" regimen that combines the hemoglobin affinity enhancer (GBT440) -- which limits oxygen delivery to tissues -- with a HIF-2α inhibitor (PT2399) to prevent compensatory erythropoiesis that can be detrimental. While this regimen extended the lifespan of the Ndufs4 KO mouse model of Leigh syndrome, its efficacy still did not match that of chronic 11% FIO2. Here we report an optimized combination that now utilizes GBT601, a second-generation hemoglobin affinity enhancer with longer half-life and greater hemoglobin occupancy, again with PT2399. Here we report that the GBT601/PT2399 combination achieved therapeutic hypoxia and demonstrated strong efficacy comparable to continuous breathing of 11% FIO2 by halting neurodegeneration and even reversing neurological symptoms in three different mouse models: Leigh syndrome, Friedreich's ataxia, and Parkinson's disease. The dual targeting regimen led to a striking extension in median lifespan in the Leigh syndrome model, from a median of ∼62 day to 158 days, when initiated after onset of advanced disease. Importantly, body weight was stable with the combination and it did not induce any signs of pulmonary hypertension, likely due to attenuation of HIF-2α. Our findings motivate additional pre-clinical and even clinical studies to evaluate the safety and efficacy of the GBT601/PT2399 combination.","42427570":"ID: 42427570\nTitle: A 3D Human Neuron-on-Chip Platform to Monitor Neuronal Injury Responses.\nAbstract: Traumatic brain injury (TBI) is a major cause of neurological dysfunction and long-term neurodegeneration, yet the intrinsic neuronal contributions to TBI pathophysiology remain incompletely defined. Here, we present a novel Neuron-on-Chip microfluidic platform that can be used to mechanically injure mature human prefrontal cortex neurons (hPFCs) embedded in three-dimensional (3D) hydrogels, enabling the study of injury responses in pure neuronal cultures. We assessed real-time calcium dynamics across 13 metrics of single-cell and network activity, revealing a biphasic injury response: an early phase (0.5-24 hr) characterized by excitotoxicity, hyper-synchronized bursting, and network collapse; and a late phase (8 d) marked by sustained depolarization and structural remodeling. Secretome profiling uncovered progressive elevations in extracellular pT181 and total Tau from days 1 to 5 post-injury. Cytokine analyses identified early (24 hr) elevations in IP-10, IL-10, IFNα2, and NCAM, and late increases (8 d) in CXCL9 and MPO, linking neuronal activity changes to stage-specific inflammatory signaling. Immunocytochemistry and immunoblotting confirmed temporally ordered upregulation of calpain-1 and active caspase-3 (days 1-3), phosphorylated Tau (AT8+, days 5-8), and neurofibrillary tangle-like Tau aggregates (NFT+, day 8). These findings establish our platform as a scalable microphysiological model for probing the dynamic cellular and molecular sequelae of neuronal response to injury, offering insights into neurodegeneration and opportunities for therapeutic discovery.","42427630":"ID: 42427630\nTitle: Shared and disease-specific human brain vascular signatures in Alzheimer's disease, frontotemporal dementia, and Huntington's disease.\nAbstract: The blood-brain barrier (BBB) plays a central role in brain function and is increasingly implicated in neurodegenerative disease. Major neurodegenerative disorders, including Alzheimer's disease (AD), frontotemporal dementia (FTD), and Huntington's disease (HD), share overlapping pathological features. Yet, the extent to which these diseases converge or diverge at the level of BBB-associated cell types remains poorly understood. Here, we performed a comparative analysis of vessel-enriched human brain transcriptomic datasets across AD, FTD, and HD to define shared and disease-specific neurovascular alterations. We identify a partially conserved transcriptional signature of vascular dysfunction across all three diseases, alongside disease-specific changes in endothelial, pericyte, and perivascular cell populations. Endothelial remodeling was most prominent in capillary and venous segments, highlighting segment-specific vulnerability along the arteriovenous axis. Notably, we identified two molecularly distinct human pericyte subtypes across all three datasets and found a consistent reduction in the matrix-type pericytes (M-peri) fraction, suggesting a selective decline. Cell-cell communication analysis further revealed reorganized endothelial-pericyte signaling networks, with prominent alterations in extracellular matrix-associated pathways, including LAMININ, COLLAGEN, FN1, and NCAM, together with changes in contact-dependent and vascular signaling pathways such as NOTCH and VEGF. Together, our findings define shared and disease-specific neurovascular mechanisms across major neurodegenerative disorders and highlight BBB-associated pathways as central features of neurodegeneration, providing a framework for future diagnostic and therapeutic strategies.","42427633":"ID: 42427633\nTitle: Synaptic activity controls local exposure of an 'eat-me' signal via ANO3-ITPR1 signaling.\nAbstract: Neuronal synapses are eliminated during brain development and disease through pruning by glial cells. Individual synapses are marked for engulfment by 'eat-me' signals, which include externalized phosphatidylserine. In apoptotic cells, phosphatidylserine externalization is driven by caspase-dependent activation of Xkr scramblases 1 and inactivation of specific flippases 2 . Localized caspase activation at neuronal synapses can mediate spatially-restricted synaptic phosphatidylserine exposure leading to synapse pruning by glial cells during development and neurodegeneration 3-6 . It is unknown which caspase-regulated flippases and scramblases promote synaptic phosphatidylserine exposure and whether there are any caspase-independent mechanisms of phosphatidylserine exposure relevant for synapse elimination. To address this question, we here develop a scalable CRISPR screening approach, COMPASS-seq (compartment-anchored sgRNA screen sequencing), to uncover the genetic underpinnings of subcellular phenotypes. COMPASS-seq is compatible with in vitro and in vivo systems and a wide range of subcellular compartments; we here apply it to the neuronal synapse. We discover that inhibition of the caspase-independent, calcium-activated anoctamin ANO3 (TMEM16C) is sufficient to increase synapse numbers in vivo . ANO3 co-localizes with IP3 receptor 1 (ITPR1), a calcium channel in the endoplasmic reticulum, to form a postsynaptic signaling platform that drives spatially restricted phosphatidylserine exposure at synapses. Activation of the ITPR1 calcium channel activity is sufficient to drive synaptic phosphatidylserine exposure via an ANO3-dependent but caspase-independent mechanism. Our results suggest a mechanism for integrating synaptic activity information to control synaptic pruning. The role of ANO3 in regulating synapses could shed light on the mechanisms underlying its numerous associations with both dementia 7 and other neurological diseases 8,9 .","42427672":"ID: 42427672\nTitle: Small molecules targeting ARF1 interaction with C9orf72:SMCR8:WDR41 complexes suppress its overactivation implicated in ALS/FTD.\nAbstract: The hexanucleotide repeat expansion in C9orf72 gene is the most common genetic cause of amyotrophic lateral sclerosis (ALS)/frontotemporal dementia (FTD). The C9orf72 protein forms a complex with SMCR8 and WDR41 (CSW), which functions as a GTPase-activating protein (GAP) regulating ARF1 and RAB small GTPases. While these findings implicated ARF1-GAP dysregulation in ALS/FTD and supported ARF1 suppression as potential intervention, small molecules that modulate ARF1-CSW interactions are lacking. In this study, we demonstrated upregulation of tyrosine-phosphorylated (Tyr-782) ASAP1 (also known as AMAP1, DDEF1, or Centaurin β4), an ARF-GAP, in human motor cortex of both sporadic ALS and ALS with C9orf72 mutations. Ectopic C9orf72 expression partially mimicked the effects of a known ARF1 inhibitor brefeldin A to disperse Golgi apparatus. Computer-aided rational drug design with high-throughput in-silico screening identified MCULE-5095997944 (Named as SCC944) as a ARF1-CSW modulator. SCC944 binds directly to ARF1 and reduced GTP-bound ARF1 levels upon ARF1 activation. SCC944 demonstrated brefeldin A-like ARF1-dependent alteration of organelle organization including Golgi, microtubules, and mitochondria, but also a protein trafficking pattern that is distinct from brefeldin A mechanism. These studies identified the first small molecule targeting ARF1-CSW interaction and further support ARF1 modulation as a potential therapeutic approach for ALS/FTD.","42427691":"ID: 42427691\nTitle: Within-electrode temporal envelope processing predicts multi-channel speech outcomes across cochlear implant pulse rates.\nAbstract: Cochlear implants (CIs) restore hearing by stimulating auditory neurons to encode amplitude envelopes across frequency bands, providing essential cues for speech recognition. This study investigated how stimulation pulse rate constrains temporal envelope processing and speech cue perception in ten post-lingually deaf CI users by evaluating amplitude modulation (AM) detection thresholds and consonant identification performance across pulse rates. The effects of pulse rate on temporal processing and speech perception were examined using both standard clinical multi-channel strategies and single-channel strategies designed to isolate within-channel envelope representations. Results revealed a significant decline in AM detection and consonant recognition performance at the lowest tested pulse rate of 125 pulses per second (pps), consistent with perceptual constraints on temporal processing at low carrier rates, rather than inadequate envelope sampling. At the highest pulse rate of 4000pps, a non-significant reduction in AM detection was observed which may be consistent with previously reported reductions in amplitude discrimination at high pulse rates. Consonant recognition performance remained stable across clinically relevant pulse rates (250-2000pps), though listener-specific pulse rate effects were observed. Notably, significant correlations were found between single-channel and multi-channel performance in AM detection and consonant recognition tasks. These findings support an important contribution of within-electrode temporal envelope processing to multi-channel speech perception and highlight the clinical relevance of individual variability in pulse rate effects.","42427719":"ID: 42427719\nTitle: Neuroticism is linked to cognitive decline and increased risk of Alzheimer's disease through dysregulation of excitatory neurons.\nAbstract: Neuroticism is an established risk factor for Alzheimer's disease (AD), yet the molecular mechanisms linking this personality trait to neurodegeneration remain poorly understood. We leveraged single-nucleus RNA-sequencing data from longitudinal cohort studies of cognitive aging (n = 655) to investigate the mechanisms mediating the association between neuroticism and AD. We identified two genes associated with neuroticism, both of which are downregulated in excitatory neurons: ADRA1B and LY6E-DT . In addition, we found that neuroticism is associated with enrichment of a specific excitatory neuron subpopulation: Exc.12. Further analysis revealed that Exc.12 partially mediates the relationship between neuroticism and AD, accounting for 12.2% of the total effect. The dysregulation of excitatory neurons may represent a key cellular change that links neuroticism to AD.","42427742":"ID: 42427742\nTitle: Selective knockout of PKA regulatory subunits reveal opposite catalytic and metabolic consequences with implications for Alzheimer's disease.\nAbstract: cAMP-dependent Protein Kinase A (PKA) is a master regulator of cell signaling involved in energy metabolism, synaptic plasticity, and stress response. Dysregulated PKA signaling is implicated in diseases including neurodegeneration and cancer. PKA catalytic activity is regulated by two nonredundant regulatory subunits, Type I (RIα/RIβ) and Type II (RIIα/RIIβ), whose divergent functions are not fully understood. We generated double-knockout (KO) cell lines of RIα/RIβ and RIIα/RIIβ subunits and performed multiplexed MS-based proteomic and phosphoproteomic profiling under basal and glucose-perturbed conditions. We found that RI and RII loss drives distinct, and often opposite, remodeling of the cellular proteome and phosphoproteome. While both mutants blunted metabolic flexibility to glycolytic stressors and stimuli, RI and RII KO cells exhibited elevated and depressed glycolytic signaling, respectively. Interestingly, RI KO increased the abundance and kinase activity of the PKA catalytic subunit Cα isoform, leading to an increase in PKA substrate phosphorylation, whereas RII KO decreased the abundance, kinase activity, and substrate phosphorylation by the catalytic subunit Cβ isoform. Notably, one of the most differentially affected PKA sites between RI and RII KOs maps to Tau, whose hyperphosphorylation is a hallmark of Alzheimer's disease. Loss of RI increased Tau phosphorylation, which was not only caused by increased PKA catalytic activity, but also a higher binding affinity of Tau to RII subunits on the negatively-charged flexible linker region. Overall, the present study demonstrates that PKA RI and RII subunits play nonredundant roles in modulating PKA activity, metabolic flexibility, and phospho-regulation of key disease-associated substrates such as Tau.","42427757":"ID: 42427757\nTitle: The human language processing system straightens natural speech.\nAbstract: Large language models trained on next-word prediction have impressive linguistic capabilities. This suggests that the goal of temporal prediction is essential to language processing, but how this goal impacts the structure of speech representations in the human brain remains unknown. Here, we test the hypothesis that prediction is facilitated by the temporal straightening of representational trajectories along the speech processing hierarchy. We developed a methodology for measuring the curvature of these trajectories using fMRI. Our method exploits a previously unknown connection between the timescale of single-unit responses and the curvature of population trajectories. We examined brain responses of subjects listening to natural speech. Response trajectories were most curved in lower-level auditory areas and progressively straightened along the cortical hierarchy. We presented the same speech stimuli and perturbed versions thereof to wavLM-a speech representation model that is well aligned with human brain responses-and found that hierarchical straightening effects are strongest for stimuli whose statistical structure resembles natural speech. Together, our results establish a direct connection between the goal of temporal prediction, the geometry of neural speech representations, and the cortical hierarchy of representational timescales.","42427758":"ID: 42427758\nTitle: Exosomal Profiling Reveals Mechanisms of Hibernation-Associated Neuroprotection.\nAbstract: Glaucoma is a group of eye diseases that affects 4 million people in the US and is one of the leading causes of vision loss due to damage to the eye's optic nerve (ON) which is composed of axons from retinal ganglion cells (RGCs) that transmit visual information to the brain. Injury to the ON often triggers RGC death and subsequent loss of visual function. Despite its increasing prevalence worldwide, effective therapies for glaucoma remain elusive. Notably, the thirteen-lined ground squirrel (TLGS) exhibits intrinsic neuroprotection during hibernation; however, reproducing this protective state pharmacologically has proven challenging. To elucidate the metabolic mechanisms underlying this resilience, we conducted untargeted metabolomic analyses on TLGS retinas at 6 hours, 3 days, and 7 days following ON crush. Retinas from awake and hibernating animals were compared to identify temporal and state-dependent metabolic signatures. Distinct metabolomic profiles were observed in hibernating animals relative to their awake counterparts. Pathway analyses revealed coordinated regulation of amino acid, lipid, and purine metabolism that likely contributes to hibernation-induced resilience. Furthermore, our findings indicate that hibernating TLGS retinas increase exosome biogenesis, prompting in vitro validation using TLGS-derived exosomes, which demonstrated robust neuroprotective and anti-inflammatory effects. Proteomic and transcriptomic characterization of exosomal cargo identified conserved miRNAs, mRNAs, and proteins implicated in redox balance, cytoskeletal stabilization, and stress-response regulation. Collectively, these data support the hypothesis that metabolic reprogramming and exosome-mediated intercellular signaling underlie hibernation-associated neuroprotection. Modulating these pathways may provide a blueprint for novel therapeutic strategies to mitigate neurodegeneration and promote recovery following optic nerve injury.","42427832":"ID: 42427832\nTitle: First worldwide multicenter validation of the POLARIS preclinical polarizer across biological models and imaging paradigms.\nAbstract: Hyperpolarized ¹³C Magnetic Resonance Imaging (HP-MRI) enables real-time, non-invasive assessment of metabolism in diseases including cancer and neurodegeneration. Broader adoption has been limited by the complexity, duration, and lack of standardization of current hyperpolarization methods. This study evaluated POLARIS Preclinical, a parahydrogen-induced polarization (PHIP) hyperpolarizer designed to streamline production of hyperpolarized ¹³C agents. Four POLARIS systems were deployed across eight international research centers to produce hyperpolarized [1-¹³C]pyruvate doses within 90 seconds. In vitro and in vivo imaging was conducted in multiple animal models using MRI systems operating at 1.4, 3, 7, and 9.4 Tesla. Metabolic conversion of pyruvate to lactate and bicarbonate was successfully measured across all sites. POLARIS enabled rapid, reproducible production of hyperpolarized [1-¹³C]pyruvate and demonstrated consistent performance across instruments, institutions, and field strengths. These results support standardized, high-throughput metabolic MRI for multicenter studies and translational research in oncology, neurology, and cardiovascular disease.","42427876":"ID: 42427876\nTitle: Grey matter degeneration during multiple sclerosis is linked to activation of neuronal necroptosis by oxidized phosphatidylcholines.\nAbstract: Oxidized phosphatidylcholines (OxPCs) are biomarkers of oxidative stress found in grey matter (GM) lesions during multiple sclerosis (MS), yet their distinct role in GM neurodegeneration remains undefined. Here we report that stereotaxic OxPC deposition in the mouse spinal cord GM induces age dependent neuroinflammation and neurodegeneration. Microglia are the predominant macrophages responding to OxPC induced GM lesions and help to mitigate acute neurodegeneration. Neuronal necroptosis activation in mouse GM lesions and neuronal upregulation of OxPCs and necroptosis activation in MS GM lesions suggest OxPC induced necroptosis promote GM degeneration during MS. In support, necroptosis inhibition ameliorates OxPC induced GM neuron loss. Finally, iron(ii)-containing heme deposition in the GM induces both OxPC formation and neuronal necroptosis activation, suggesting an endogenous upstream mechanism for generating neurotoxic OxPCs. These results highlight a plausible link between heme deposition, lipid peroxidation, and neuronal loss, and that necroptosis inhibition could help prevent GM neurodegeneration during MS.","42427919":"ID: 42427919\nTitle: 3D Electrical Impedance Tomography of Regional Ventilation During Jet Ventilation: A Pilot Study.\nAbstract: Low-frequency jet ventilation (LFJV) is commonly used in laryngotracheal surgery when intubation is not feasible. However, limited understanding of regional ventilation and distal airway pressures raises safety concerns and restricts broader adoption. This study employed electrical impedance tomography (EIT) to quantify tidal volumes and regional ventilation patterns in patients undergoing airway surgery with LFJV. Adult patients undergoing microlaryngeal surgery for subglottic stenosis were prospectively recruited from the Laryngology Clinic. A standardized anesthesia protocol was followed. EIT was used to measure tidal volumes and assess regional ventilation during bag-mask ventilation, laryngeal mask airway (LMA) ventilation, LFJV before and after dilation, and during recovery. Linear mixed-effects models were applied to compare LFJV with LMA ventilation, accounting for repeated measures within subjects. Six patients underwent surgery with EIT monitoring, of whom four had complete datasets for analysis. LFJV preferentially ventilated apical lung regions, while basal regions were consistently under-ventilated. Apical-to-basal volume ratios were consistently higher during LFJV compared with LMA (> 100% higher). Similar differences were observed in the global inhomogeneity index (24% higher), left-to-right ratio (21% higher), and anterior-to-posterior ratio (9.5% higher). This is the first study to apply EIT to assess ventilation distribution during LFJV for microlaryngeal surgery. LFJV was associated with relative hypoventilation of basal and dorsal lung regions and increased ventilation inhomogeneity compared with LMA ventilation. Larger studies are warranted to validate these results and inform optimization of LFJV in clinical practice. 4.","42427968":"ID: 42427968\nTitle: Differential Cognitive Strategies for Speech-in-Noise Perception: A Comparative Study Between Yoga Practitioners and Non-practitioners.\nAbstract: Speech perception in noise varies widely even among normal-hearing individuals and is strongly influenced by cognitive factors such as attention, working memory and linguistic abilities. Yoga is known to enhance these domains, yet its potential impact on speech-in-noise perception remains insufficiently explored. This study investigated whether yoga practitioners (YP) demonstrate superior speech-perception-in-noise (SPIN) performance compared to non-practitioners and whether differences could be attributed to enhanced selective attention, working memory and linguistic processing capabilities. Sixty young adults (18-30 years) with normal hearing were recruited: 30 YP with a mean practice duration of 4.79 years and 30 non-yoga practitioners (NYP). Speech identification in noise was assessed using Kannada low-predictive sentences presented with speech babble and speech-shaped noise at varying signal-to-noise ratios. Cognitive measures included Stroop tasks (selective attention), digit span and N-back tests (working memory) and moving-average type-token ratio and generative naming (linguistic abilities). Scores were converted to rationalised arcsine units and group differences were analysed using independent t-tests and Mann-Whitney U tests. Stepwise linear regression identified predictors of SPIN performance. YP demonstrated significantly superior performance in speech babble at 0 dBSNR (p = .009) but not in speech-shaped noise conditions. Regression analyses revealed distinct predictive patterns: vocabulary (generative naming) predicted 26% of variance in NYP (β = 0.534, p = .002), while working memory (backward digit span) predicted 11.6% of variance in YP (β = 0.383, p = .037). Cognitive and linguistic measures showed no significant group differences. YP exhibited superior speech identification under informational masking conditions, mediated by working memory capacity. Our findings suggest that yoga practice is associated with a shift from vocabulary-based to working memory-based strategies for speech-in-noise perception.","42428043":"ID: 42428043\nTitle: Speech-based depression detection using higher-order spectral features and a multi-level transformer.\nAbstract: A precise and prompt automated depression detection system utilizing auditory signals is essential, considering the scarcity of psychiatrists and the exorbitant expense of clinical diagnosis, resulting in approximately 60% of psychiatric patients globally lacking access to mental health care. This study proposes a Depression Detection model utilizing voice, which integrates hierarchical higher-order spectral distribution with deep learning models to overcome these issues. The utilized dataset is the Distress Analysis Interview Corpus, Wizard of Oz (DAIC-WOZ), comprising audio recordings of clinical interviews designed to facilitate the detection of psychological distress disorders such as depression, anxiety, and post-traumatic stress disorder. Two categories of features are extracted: statistical, handmade and bispectral features, as well as deep features utilizing the Multi-level Convolutional Transformer with attention learning (ML-CoT-AL) model. The ML-CoT-AL integrates the Convolutional Transformer (CoT), Channel and Element-wise Attention Module (CEAM), and Negotiator Modules (NM). The study presents the RIME optimization technique utilizing ML-CoT-AL for hyperparameter tuning, leading to improved accuracy in multi-level depression identification.","42428047":"ID: 42428047\nTitle: Linguistics and human brain: a perspective of computational neuroscience.\nAbstract: Elucidating the language-brain relationship requires bridging the methodological gap between linguistics' abstract theoretical frameworks and neuroscience's empirical neural data. As an interdisciplinary cornerstone, computational neuroscience formalizes language's hierarchical and dynamic structures into testable neural representation models through modeling, simulation, and data analysis, enabling computational dialogue between linguistic hypotheses and neural mechanisms. Recent advances in deep learning, particularly large language models (LLMs), have further advanced this inquiry: their high-dimensional representational spaces provide a new scale for probing the neural basis of linguistic processing, the model-brain alignment framework offers a principled approach to evaluating the biological plausibility of language-related theories, provided that representational correspondence is interpreted together with behavioral, temporal, causal, and biological constraints. This review synthesizes interdisciplinary progress from a computational neuroscience perspective. First, it outlines the core connotations of major linguistic frameworks (generative grammar, functional linguistics, and cognitive linguistics), their cross-cultural and evolutionary characteristics, and key challenges for neural alignment, including limited quantitative mechanisms, poor accessibility of abstract constructs to neural measures, and insufficient treatment of dynamics and plasticity. Second, it introduces the methodological foundations of linguistics-neuroscience dialogue, focusing on four technical pillars: neural activity measurement (e.g., fMRI, EEG, MEG, fNIRS, ECoG, SEEG), linguistic numerical representation, the evolution of language models from statistical approaches to LLMs, and neural coding frameworks that link model representations to brain signals, illustrated with a model-brain alignment case study. Third, it summarizes major findings, ranging from early computational insights into predictability and structural processing to recent LLM-driven progress in cross-modal interaction, inter-brain coupling, hierarchical computation, learning strategy sensitivity, and language plasticity. Finally, the review discusses current limitations-including functional alignment without structural homology, constraints on real-time validation, biased research coverage, and narrow evaluation metrics-and proposes future directions, such as exploring whether spiking neural network-based language models can improve biological plausibility in settings requiring temporally precise and event-driven neural modeling, developing cognitive-level alignment frameworks integrating memory, causality, and metacognition, and extending clinical applications. In summary, this work aims to advance a comprehensive, mechanistic understanding of the language-brain relationship and promote computational neuroscience as a generative theoretical framework for testable neuro-computational accounts of language.","42428055":"ID: 42428055\nTitle: NSAID use is associated with lower dementia and Alzheimer's disease prevalence and slower cognitive decline: A retrospective longitudinal analysis of the NACC cohort.\nAbstract: Dementia, particularly Alzheimer's disease (AD), is a major global health challenge, with prevalence projected to reach 150 million cases by 2050. AD is characterized by progressive cognitive decline linked to neuroinflammation and neurodegeneration. Non-steroidal anti-inflammatory drugs (NSAIDs) have been explored as potential neuroprotective agents, particularly diclofenac, which has been proposed to modulate microglial inflammasome signaling. However, prior studies investigating NSAIDs in AD have yielded inconsistent findings. We therefore reexamined the relationship between selected NSAIDs and dementia outcomes in a large longitudinal cohort from the National Alzheimer's Coordinating Center (NACC). We analyzed cross-sectional and longitudinal data from the NACC database collected between 2005 and 2022. Associations between NSAID exposure and dementia, AD, and cognitive trajectories were examined. Propensity score matching was performed to compare NSAID users with matched non-users while adjusting for demographic and clinical confounders. Longitudinal mixed-effects models were used to assess cognitive decline based on Montreal Cognitive Assessment (MoCA) scores. Among 47,165 participants, diclofenac and naproxen use were associated with a lower prevalence of dementia and AD compared with matched non-users, whereas etodolac showed no significant associations. Diclofenac users demonstrated reduced odds of dementia and AD. Naproxen showed similar cross-sectional associations. In longitudinal modeling, diclofenac users had a significantly slower rate of cognitive decline than non-users. These findings suggest a compound-specific association between NSAID use and AD, with diclofenac potentially modulating disease progression through anti-inflammatory mechanisms. The observed modulation of longitudinal cognitive decline supports further investigation of inflammatory pathways, including microglial and inflammasome signaling, as therapeutic targets in biomarker-defined AD populations.","42428129":"ID: 42428129\nTitle: Association between motor cortex grey matter loss and inability to control an ECoG-based implanted Brain-Computer Interface in ALS.\nAbstract: The field of implantable Brain-Computer Interfaces (iBCIs) is rapidly advancing, with individuals with amyotrophic lateral sclerosis (ALS) as key beneficiaries. However, ALS-related cortical degeneration may impair iBCI effectiveness. This study investigated whether structural magnetic resonance imaging (MRI) and functional MRI (fMRI) metrics are associated with the quality of electrocorticography (ECoG) signals critical for iBCI use. Six late-stage ALS participants and 76 controls underwent T1-weighted structural MRI and task-based fMRI during right-hand movement or attempts thereof. ECoG data of ALS participants was benchmarked using ECoG data acquired in epilepsy patients. Grey matter thickness in the sensorimotor cortex and fMRI activation in the motor-hand area were measured. Four ALS participants showed >0.4 mm thinning in the precentral gyrus, while the postcentral gyrus was spared. ECoG signal quality was significantly associated with precentral grey matter thickness, but not with fMRI activity. These findings suggest that presurgical assessment of precentral grey matter thickness could potentially prove useful for iBCI candidate selection in advanced ALS. People with amyotrophic lateral sclerosis (ALS) can lose the ability to move and speak, but their thinking often remains intact. Implantable brain-computer interfaces (iBCIs) can help by translating brain signals into commands for communication devices. However, ALS damages the motor cortex, which may reduce the quality of these signals. In this study, we examined brain scans and electrical recordings from six people with advanced ALS. We found that thinning of the motor cortex was linked to weaker brain signals needed for iBCI control, while functional MRI activity was less predictive. This suggests that measuring motor cortex thickness before surgery could help identify who will benefit most from an iBCI, improving treatment decisions and future clinical trials. We examine presurgical MRI/fMRI and ECoG recordings from people with advanced ALS receiving implanted brain-computer interfaces. Motor cortex thinning is associated with poorer ECoG signal quality, suggesting cortical thickness may help identify candidates likely to benefit.","42428154":"ID: 42428154\nTitle: Chorea as a Non-Thrombotic Manifestation in an Adolescent with Systemic Lupus Erythematosus, Antiphospholipid Syndrome and Heterozygous Prothrombin G20210A Gene Mutation: A Case Report.\nAbstract: Chorea is a rare movement disorder in the context of systemic lupus erythematosus (SLE). Although basal ganglia thrombosis, autoimmune injury or neuronal direct lesion have been proposed as possible explanations, its mechanism is still unknown. It is important to understand its pathogenesis so that the best treatments can be identified. A 12-year-old female adolescent with choreoathetoid movements of the trunk and four limbs, slurred speech, hypophonia and orofacial dyskinesia with 14 days of evolution. Brain magnetic resonance imaging revealed recent subcortical ischemic lesions in both frontal and parietal lobes. Basal ganglia lesions were not found. She started acetylsalicylic acid (ASA) and tetrabenazine, with chorea improvement. Transcranial Doppler ultrasound identified a microembolic sign between the left middle cerebral and anterior cerebral arteries. Therefore, ASA was switched to enoxaparin. Antinuclear antibodies and lupus anticoagulant (LAC) antibody were positive, with heterozygous prothrombin G20210A gene mutation being found. Five-day methylprednisolone pulses 1 g/day were performed, followed by prednisolone 60 mg/day. Intravenous immunoglobulin was administered, and hydroxychloroquine was initiated. Due to progressive microscopic hematuria and non-nephrotic proteinuria, a kidney biopsy was performed, being compatible with class V lupus nephritis. Consequently, mycophenolate mofetil and enalapril were started. Chorea resolved 5 days later. After discharge, LAC remained positive, but no more neurologic symptoms occurred. Basal ganglia thrombosis does not seem to be the most likely mechanism of SLE-related chorea. Antiphospholipid antibodies alone do not seem to be enough to trigger chorea. Further studies are needed to clarify the mechanisms that trigger this movement disorder.","42428165":"ID: 42428165\nTitle: Multifactorial determinants of complications and patient-reported outcomes in metal clasp-retained removable partial dentures.\nAbstract: This cross-sectional study aimed to evaluate the distribution of complications in clasp-retained removable partial dentures (C-RPDs) and to investigate the influence of denture design parameters, denture age, and Kennedy and Eichner classifications on complication patterns and patient-reported outcomes. 134 patients wearing 205 metal C-RPDs were included. Biological and mechanical complications were recorded. Denture design parameters (major connector type, clasp type and number, and rest number) were documented. Oral health-related quality of life Oral health-related quality of life (OHRQoL) and patient satisfaction were assessed using the OHIP-14 and a visual analog scale (VAS). Associations between complication patterns, design parameters, denture age, classifications and patient-reported outcomes were statistically analyzed. Mechanical complications were the most frequently observed complications. Mechanical complications and ulcerations were significantly associated with reduced OHRQoL. Denture age demonstrated a significant association with mechanical complications and patient-reported outcomes. Classifications showed limited associations with complications and did not influence patient-reported outcomes. Palatal plate and anteroposterior palatal strap designs were associated with physical pain and reduced speech satisfaction. In the mandible, dentures incorporating both circumferential and bar clasps demonstrated higher satisfaction, whereas the exclusive use of bar clasps was associated with increased physical disability. Higher numbers of rests and clasps were associated with lower overall OHIP-14 scores. Denture age and design characteristics were associated with complication patterns and patient-reported outcomes. Mechanical complications were more frequently observed in older dentures and, together with mucosal ulcerations, were associated with reduced OHRQoL. These findings suggest that individualized design strategies, regular follow-up, and timely maintenance may contribute to better mechanical stability and patient-centered outcomes in C-RPDs.","42428500":"ID: 42428500\nTitle: Mitochondrial-targeted actions of lycopene: evidence, mechanisms and future directions.\nAbstract: Lycopene (LYC; C40H56), a dietary carotenoid, has emerged as a promising modulator of mitochondrial physiology across multiple cell types and animal models. Here we critically synthesize experimental evidence that LYC attenuates mitochondrial oxidative stress, preserves oxidative phosphorylation complex function and ATP production, reduces mitochondrial permeability transition and cytochrome-c-dependent apoptosis, and regulates mitochondrial quality-control pathways including mitophagy and (less consistently) biogenesis. Mechanistic readouts indicate activation of antioxidant axes (Nrf2/HO-1), modulation of SIRT1/SIRT3 and PGC-1 signaling, and downstream effects on Bcl-2 family proteins and caspase activation; targeted delivery systems (mitochondria-directed nanodots) further enhance mitochondrial targeting and functional rescue in neurodegeneration models. However, the literature shows substantial heterogeneity in experimental designs (dose, route, timing), mostly relies on injury/toxin paradigms, and frequently reports molecular changes without causal perturbation (genetic or pharmacologic) to establish mechanism. Importantly, data on mitochondrial dynamics (fusion/fission) remain sparse and mechanistic links between mitophagy, biogenesis and improved bioenergetics are often associative rather than causal. The objective of this review is to evaluate available evidence on how LYC modulates mitochondrial function, redox biology, biogenesis, dynamics, and autophagy (mitophagy), as well as mitochondria-dependent apoptosis, in animal and human cells, identify critical gaps, and propose experimental priorities to move the field toward translational studies. This work is concluded with concrete recommendations for mechanistic and translational research to validate LYC as a mitochondria-targeting agent.","42428530":"ID: 42428530\nTitle: Defining the Level of Need and Total Intervention Time in Children's Speech and Language Therapy in Finland: Developing a Consensus-Based Guideline.\nAbstract: Speech and language therapy is essential for supporting the skills and participation of children with disorders that impair their ability to interact, communicate, understand or use language, speak, eat or swallow. However, it might be challenging to outline how much intervention should be recommended for each individual. Currently, there are no guidelines to support clinical decision-making regarding the child's level of need for intervention, and thus, the recommended amount of speech and language therapy. The aim of the present work was to create a consensus-based guideline for clinical use in speech and language therapy in Finland to enhance equitable treatment and purposeful allocation of resources. This guideline was designed to assist in evaluating the child's level of need for intervention and, based on that, the total intervention time of speech and language therapy for children up to 17 years of age. A work group of Finnish speech and language therapists created a consensus-based guideline regarding the level of need for intervention and total intervention time during a 3-year process. During this time, the guideline was improved through a pilot phase following three comment rounds, including expert evaluations, conducted within the field of speech and language therapy as well as among other stakeholders. The ACCORD guideline was used to report this consensus work. A guideline including a framework for outlining the level of need for intervention was developed to support clinical decision-making regarding the total intervention time per year of speech and language therapy for children up to 17 years. The guideline is based on the International Classification of Functioning, Disability and Health and the idea of adaptive intervention. Four factors were considered essential: (1) impact the disorder has on participation, (2) need for consultative support, (3) severity of the disorder, and (4) expected benefit of the intervention. Application of the guideline in the Finnish context and expert evaluations on the guideline and its validity are presented. We developed a guideline to define the child's level of need for intervention and total intervention time. The content validity of the guideline was high based on the ratings by the expert evaluators. We hope that this guideline will support clinical decision-making regarding total intervention time per year in Finland and support the creation of similar guidelines in other contexts. The present guideline may facilitate both intradisciplinary and interdisciplinary discussion regarding the child's level of need for intervention, and based on that, the recommended total intervention time. Systematic considerations of predefined factors used to define the level of need for intervention may enhance more equitable national practices.","42428551":"ID: 42428551\nTitle: Acylglycerol Kinase Inhibition Restores Mitophagy and Alleviates Alzheimer's Disease Pathology.\nAbstract: Mitophagy is a conserved cellular process that removes dysfunctional or excess mitochondria. Increasing evidence suggests that impaired mitophagy plays a crucial role in AD development. Promoting mitophagy has been shown to be protective in models of AD, representing an important target of Alzheimer's disease (AD). However, the molecular mechanisms underlying impaired mitophagy in AD are still elusive. Here, we provide evidence that highly expressed acylglycerol kinase (AGK), a mitochondrial lipid kinase associated with mitochondrial protein transport, glycolysis, and platelet formation, is a key mediator of mitophagy in AD. We found that AGK promoted the binding of ATPase family AAA domain containing 3A to translocase of the inner mitochondrial membrane 23 and sequentially increased mitochondrial import of PTEN-induced putative kinase 1, leading to the decrease of mitophagy. Further investigations revealed that the AGK downregulation in neuronal cells and APP/PS1 mice enhanced mitophagy, increased mitochondrial membrane potential, decreased pathological Tau/Aβ and neuroinflammation, and alleviated cognitive dysfunctions in the mice. Altogether our findings indicate that AGK plays a critical role in mediating mitophagy defects in AD; furthermore, downregulation of AGK promotes mitophagy and the decrease of Aβ and pathological Tau, providing an encouraging therapeutic treatment for AD.","42428597":"ID: 42428597\nTitle: Massage Therapy for a Voice Student with Behavioral Dysphonia When Singing: A Case Report.\nAbstract: Behavioral dysphonia is a voice condition in which inefficient muscle tension and misuse interrupt the ability of the body to produce the desired vocal function and quality. Treatment methods typically incorporate traditional voice therapy with manual laryngeal manipulation. A lack of treatment approaches for dysphonia exists that address the vocal system including all its subsystems (i.e., breath, phonation, resonance, articulation) and posture. A limited number of reports exist describing the effect of massage therapy to address the vocal system anatomy of a singer with behavioral dysphonia. This case report explores the effects of a massage protocol targeting the vocal system of a person with symptoms of behavioral dysphonia when singing. A massage student completing an 8-month massage therapy program performed 90-min massage sessions twice a week for 3 weeks on a 33-year-old student singer/songwriter referred by his vocal instructor with symptoms of behavioral dysphonia. Symptoms presented only during singing and included \"tensing up,\" effortful voice, and vocal fatigue. Massage therapy sessions targeted the structure, musculature, and connective tissue of the whole vocal anatomy. Acoustic, aerodynamic, and physical outcomes were measured pre and post treatment. Baseline forward head posture, elevated shoulder position, cervical hyperlordosis, and thoracic hyperkyphosis, as well as thoracic/head/neck engagement during singing all decreased. Low laryngeal posture neutralized. Vocal range increased by six whole tones. Despite between-session variability, following the final session, loudness had increased by 6 dB, peak expiratory flow by 174 L/min, and inspiratory abdominal wall movement by 5 cm. Maximum phonation time improved within all sessions except on the final day. Functional measures for respiratory fluency, harmonics-to-noise ratio, and vocal range during singing all improved. Singing Voice Handicap Index improved by 9 points but remained below norms. A massage protocol addressing the whole vocal anatomy produced positive aerodynamic, acoustic, and physical outcomes in a person who presented with behavioral dysphonia when singing.","42428685":"ID: 42428685\nTitle: Defining Frailty in Chinese-Language Biomedical Literature (2014-2024): A Decade of Conceptual Evolution.\nAbstract: Frailty is increasingly recognized as a central concept in aging research and clinical practice, which reflects reduced physiological reserve and heightened vulnerability to stressors. While extensively examined in Western biomedical literature, how frailty is defined and conceptualized in Chinese-language biomedical research remains insufficiently explored. This systematic review examined frailty definitions in Chinese biomedical publications from 2014 to 2024, analyzing definitional sources, conceptual emphases, and temporal trends. Searches across major Chinese and international databases identified 1804 eligible articles. Results show growing alignment with international frameworks, particularly through expert consensus statements, alongside improving terminological standardization. However, biomedical interpretations remain dominant, with limited attention to psychological, social, dynamic, and reversible dimensions. Emerging contributions from traditional Chinese medicine introduce distinct perspectives centred on balance and restoration. Clarifying these definitional patterns is essential for cross-cultural comparability and the development of culturally relevant frailty research and clinical practice.","42428712":"ID: 42428712\nTitle: An Unusual Cause of Ataxia in Patient with Sjogren's Syndrome: Metronidazole Neurotoxicity.\nAbstract: Cerebellar ataxia associated with metronidazole is rare. Sjögren's syndrome (SS), a chronic autoimmune disease, can also rarely present with neurological symptoms such as cerebellar ataxia. In this report, we aimed to present a 40-year-old female patient diagnosed with SS who developed acute-onset speech disorder and imbalance. The patient's complaints developed shortly, four days, after taking metronidazole for a vaginal infection. Her neurological examination revealed a broad-based gait, explosive speech, and bilateral dysmetria. Routine blood tests, nerve conduction studies, and cerebrospinal fluid analysis were normal. Brain magnetic resonance imaging showed hyperintensity in the dentate nuclei of the cerebellum, consistent with metronidazole-induced neurotoxicity. The patient's symptoms rapidly improved after discontinuation of the drug, and the lesions had completely resolved on imaging one month later. Apart from neuropathy and cerebellar degeneration, which are the most common etiologies of ataxia in Sjögren's syndrome, rare metronidazole-induced neurotoxicity was observed in our patient. Metronidazole-induced neurotoxicity may be a potentially reversible cause of cerebellar symptoms, and its recognition based on typical radiological features is important for drug withdrawal and complete recovery.","42428865":"ID: 42428865\nTitle: Free-Electron Laser-Based Extended Wide-Field Mid-Infrared Photothermal Imaging for Biomedical and Microplastic Analysis.\nAbstract: Wide-field mid-infrared photothermal (MIP) imaging offers rapid label-free chemical contrast for biomedical and polymer analysis. Its field of view (FOV) depends on the mid-infrared pump power of infrared lasers. Here, a wide-field MIP microscope is presented using up to 150 nJ pulse energies of a free-electron laser (FEL) as the pump source to achieve a larger FOV compared to a quantum cascade laser (QCL) excitation with typically 1 nJ pulses. Both implementations use counter-propagating beam paths with a microsecond pulsed 450 nm LED as the probe source and a CMOS camera that records images using a virtual lock-in detection scheme. FEL's higher pulse power expands the FOV by approximately a factor of 20, enabling submicron-resolution wide-field MIP imaging of polystyrene beads, single cells, and a murine brain tissue section. QCL systems with less intense pump pulses achieve only 45 μm FOV for samples including polystyrene beads, Mycobacterium tuberculosis-infected fixed tissue sections, and laryngeal cancer cryosections. IR spectra are reconstructed by tuning FEL and QCL wavelengths and collecting a series of wide-field images. We discuss current challenges and further improvements to implement high-power mid-IR pump lasers and shorter pulse probe sources for wide-field MIP imaging with even larger FOVs in the context of biomedical diagnostics and microplastic screening.","42428879":"ID: 42428879\nTitle: From Air to Brain: Environmental Nanoparticles as Modifiable Risk Factors for Neurodevelopmental, Neurodegenerative, and Mental Disorders.\nAbstract: Ultrafine particles (≤100 nm) and other environmental nanoparticles have emerged as biologically active pollutants that can cross biological barriers, including the blood-brain barrier and the placenta. Growing evidence implicates ultrafine particles in a wide range of neuropsychiatric conditions, yet their effects remain poorly integrated into clinical and public health frameworks. In this review, we distinguish between size-defined ultrafine particles (UFPs, ≤100 nm), composition-defined environmental nanoparticles originating from combustion and secondary formation processes, and engineered nanomaterials (ENPs), which differ in physicochemical properties, exposure scenarios, and regulatory status. This narrative systematic review synthesizes findings from human and experimental studies on the neuropsychiatric and neurodevelopmental effects of environmental nanopollutants. A structured search was conducted in PubMed, Web of Science, Scopus, and Google Scholar up to November 2025, following explicit inclusion and exclusion criteria. Eligible studies included peer-reviewed human and animal research assessing mental health or neurological outcomes of nanopollutant exposure. Epidemiological studiesprimarily involving traffic-related air pollution and mixed combustion-derived ultrafine particle exposuressuggest associations with increased risk of cognitive impairment, autism spectrum disorder, depression, schizophrenia, and neurodegenerative diseases, including Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis. Prenatal and early life exposures were linked to cortical thinning, altered neurodevelopmental trajectories, and early proteinopathies. Underlying mechanisms include neuroinflammation, oxidative stress, and protein aggregation. Despite methodological heterogeneity, the evidence supports the urgent need for regulation and prevention. Environmental nanopollutants constitute an under-recognized, modifiable risk factor for neuropsychiatric and neurodegenerative conditions. A paradigm shift is needed to incorporate environmental exposure history into mental health research, risk assessment, and prevention strategies. Regulatory action targeting nanopollutant emission and exposure, particularly in vulnerable populations, is critical to mitigating long-term neurological consequences.","42429179":"ID: 42429179\nTitle: Precision Medicine in Neurodegeneration with Brain Iron Accumulation (NBIA) Disorders: An Update on Emerging Treatments.\nAbstract: Neurodegeneration with Brain Iron Accumulation (NBIA) is a heterogeneous group of heritable, mostly recessive, progressive neurodegenerative diseases characterized by iron deposition in the basal ganglia and brainstem. There are no solid global epidemiological data on prevalence and incidence of NBIA subtypes, but registry data and expert opinion suggest PKAN, BPAN, PLAN, and MPAN are the most common subtypes. NBIA disorders present with a wide spectrum of clinical symptoms, including movement disorders (dystonia, parkinsonism, chorea), pyramidal involvement (eg, spasticity), speech and cognitive deficits, motor and cognitive slowing, and ocular abnormalities. Treatment remains symptomatic, though several new drugs are in development. Following our review published in 2021, this article provides an updated summary of recent developments. We discuss the rationale of new compounds, summarize clinical trials or-in their absence-preclinical studies for NBIA subtypes. The article is divided into two sections: one section on general approaches based on the shared feature of increased iron in the brain; and the second section on tailor-made, mechanistic treatments for the various NBIA subtypes targeting the specific molecular and cellular pathways of the affected enzyme including gene therapy. In summary, randomized controlled trials in NBIA have not yet demonstrated substantial benefit, neither for iron removal, in general, which appears to be clinically ineffective in most subtypes, except aceruloplasminemia; nor for subtype-specific approaches. Several ongoing studies are exploring more dedicated compounds in this exciting field.","42429266":"ID: 42429266\nTitle: Gait speed and future ambulatory status in amyotrophic lateral sclerosis: a retrospective observational study with implications for power wheelchair referral.\nAbstract: Amyotrophic lateral sclerosis (ALS) causes rapid and progressive loss of ambulation resulting in immobility. A power wheelchair (PWC) increases safety, independence, and quality of life, however, the PWC referral process is lengthy and complex. When the PWC is delayed, immobility complications can occur. One barrier is the lack of a universal predictive \"gait speed threshold\" to help clinicians determine when to initiate the PWC referral process. Identify a clinically relevant gait speed threshold associated with future loss of ambulation in people with ALS. This was a retrospective chart review of a single multidisciplinary ALS Center of Excellence from July 1, 2016 - July 1, 2019 (36-months). Participants were included in this study if they were adults (age >18 years) with clinically definite ALS who were ambulatory at baseline. The primary outcome was gait speed on the 10-meter walk test. Secondary outcomes included the ALS Functional Rating Scale-Revised, forced vital capacity, falls, and ambulation status. Of N = 180 people with ALS identified during the study period, n = 72 met inclusion for analysis with a mean age 66.1 ± 11.9 years, 64% male, 76% with an ALS phenotype of spinal onset, and 24% bulbar onset. A gait speed threshold of 0.79 m/s maximized the combined sensitivity and specificity for classifying ambulatory status at the subsequent 6-month visit. Faster gait speeds (>1.2-1.4 m/s) were associated with greater odds of remaining ambulatory at 6-months based on Bayesian logistic regression. A gait speed threshold of 0.79 m/s was associated with increased likelihood of subsequent loss of ambulation, though modest predictive accuracy limits its use as a stand-alone indicator. Gait speed may serve as one component of clinical decision-making regarding PWC planning and referral in people with ALS. Larger multicenter studies are needed to confirm and generalize results across ALS phenotypes.","42429311":"ID: 42429311\nTitle: Velopharyngeal Anatomy and Speech Production in Cleft Palate Surrounding Primary Palatoplasty: Protocol for a Prospective Observational Pilot Study.\nAbstract: Children with cleft palate often experience impaired speech due to atypical velopharyngeal anatomy following palate repair surgery. While surgical repair aims to restore the function of the palate, more than one-third of cases result in continued velopharyngeal insufficiency (VPI) and require reoperation, which can result in negative psychosocial impacts and financial burden. Common surgical approaches for primary palatoplasty, including intravelar veloplasty and double-opposing Z-plasty, have similar reported rates of VPI. Furthermore, procedure selection occurs without any presurgical imaging and varies by operating surgeon. Surgical decisions are often based on intraoperative judgment rather than objective measures. Structural and functional variables have been associated with speech outcomes in this population, but these data exist independently of one another until the school-age years, failing to establish a direct connection between anatomy and functionality of the velopharynx in toddlers. The current clinical paradigm misses a critical window of opportunity for earlier diagnosis of VPI. The purpose of this study is to (1) establish which presurgical anatomical variables are predictive of surgical procedure selection based on perceptual assessment of intraoperative tension for palate repair and (2) determine which postsurgical anatomical features are associated with the greatest diversity in oral stop consonant production at 18 months in children with a repaired cleft palate. A total of 30 infants with cleft palate will be recruited prior to palate repair. Within 2 weeks of repair, participants will undergo nonsedated magnetic resonance imaging (MRI) of the velopharynx and produce a home-based speech recording. Participants will complete the same protocol after palate repair at 18 months of age. Data will be analyzed by independent raters following completion of a training protocol. Anatomical dimensions of the velopharynx will be extracted from the MRI scans. The number and diversity of oral stop consonants will be extracted from the speech recordings. Interrater and intrarater reliability will be assessed. Logistic regression will be used to evaluate which presurgical anatomical measurements are predictive of surgical procedure selection. Analysis of covariance will be used to examine whether postsurgical anatomical measurements are associated with diversity of oral stop consonant production. This project was funded in August 2024. Data collection began in April 2025. As of April 4, 2026, a total of 8 participants had been enrolled, and data analysis had not begun. Results are anticipated in 2027. This study will use nonsedated MRI to investigate how velopharyngeal anatomy influences surgical decision-making and early speech outcomes. Such knowledge may be useful for presurgical planning and early monitoring of postsurgical speech outcomes in children with cleft palate.

A silicone voice prosthesis (valve) allows voicing. To minimise health risks, valves must be changed swiftly if they fail. While self-management of health conditions is considered a key NHS objective, few people with laryngectomy in the UK change their own valve, requiring ongoing clinic attendance and healthcare professional input. To explore the perspectives of people with laryngectomy on self-changing, determining pertinent factors in decision-making around valve change methods with a view to informing clinical practice and supporting provision of personalised care. Ten semi-structured interviews were carried out online and via telephone. Five 'self-changers' and five participants using clinician-led valve changes were recruited via social media and charitable organisations. Reflexive Thematic Analysis was used to generate themes within the data. Thematic analysis generated three main themes. (1) My valve, my way; (2) Unequal relationships; (3) A search for normality. Data synthesis revealed patient perspectives on life with surgical voice restoration, which have otherwise not been explored in research to date. Valve leaks were associated with distress and linked to diminished social participation and quality of life. Barriers and facilitators to self-changing were highly individual, indicating the need for a personalised approach to education and decision-making around self-changing. Perceptions of disempowerment were expressed by people with laryngectomy, with limited opportunities for shared decision-making and an imbalance of power between patient and healthcare professional. Analysis also showed that self-changing may offer benefits by reducing the impact of valve changes on quality of life. Laryngectomy and surgical voice restoration have a significant impact on the activity and participation of people with laryngectomy. Empowering people with laryngectomy to participate in shared decision-making around their care is essential. A personalised approach is required, including the provision of tools, support and opportunity to jointly make decisions around valve change methods. Clinical implications include the core elements of decision-making conversations and training processes alongside points to consider for individual clinicians, service managers and policy makers. Further research on treatment burden and shared decision-making tools is warranted. What is already known on the subject Surgical voice restoration, using a silicone voice prosthesis (valve) to allow voice production, is considered the gold-standard in re-establishing communication after laryngectomy. The lifespan of each valve is finite, requiring swift replacement upon failure, to minimise health complications. Despite NHS objectives encouraging self-management of health conditions, a minority of people with laryngectomy learn to change their own valves; most remain reliant on healthcare professionals for valve changes. Little is known about the impact of this on daily life, as perspectives of people with laryngectomy have not been sought to date. What this paper adds to existing knowledge This study adds to the limited evidence-base around self-management in laryngectomy and represents the seldom-heard perspectives of people with laryngectomy on the consequences of surgical voice restoration on daily life. We report inequitable waiting times for valve changes and lack of confidence in out-of-hours care. We highlight pertinent factors in decision-making around valve change methods and reveal perceptions of disempowerment and restricted choice experienced by some people with laryngectomy who undergo surgical voice restoration. We raise queries over whether current practice meets multi-disciplinary recommendations around offering self-changing where appropriate. What are the potential or actual clinical implications of this work? This study demonstrates the need for a personalised approach to decision-making around valve management in surgical voice restoration. We recommend increased support and opportunity for shared decision-making in clinical practice and further research into the treatment burden of surgical voice restoration and the impact on quality of life after laryngectomy. Core elements of shared decision-making conversations and training processes pertinent to self-changing are discussed, with direct applicability to clinical contexts. Specific and actionable clinical implications are provided, relevant to individual clinicians, service managers and policy makers.","42429356":"ID: 42429356\nTitle: Infliximab for laryngopharyngeal involvement in Behçet's syndrome.\nAbstract: Laryngopharyngeal involvement in Behçet's syndrome is rare but clinically significant because it may cause severe odynophagia, dysphagia, and airway compromise. Optimal treatment has not been established, and irreversible structural sequelae, including laryngopharyngeal stenosis and ulcer scarring, may occur. We describe two men with Behçet's syndrome and symptomatic laryngopharyngeal involvement who showed rapid improvement after infliximab administration following an insufficient response to corticosteroids. In case 1, a 25-year-old man was classified as having suspected Behçet's syndrome based on recurrent oral ulcers, pharyngeal ulceration, arthritis, folliculitis-like skin lesions, and previous episodes of abdominal pain. He developed severe pharyngeal pain and dysphagia due to ulcerative lesions extending from the posterior pharyngeal wall to the esophageal inlet. Intravenous prednisolone resulted in limited endoscopic and symptomatic improvement, whereas infliximab promptly relieved pain and restored oral intake, with no recurrence over 14 years of follow-up. In case 2, a 29-year-old man presented with recurrent fever, oral aphthae, genital ulcers, arthritis, erythema nodosum-like lesions, and pharyngeal and laryngeal mucosal lesions associated with dysphagia. His symptoms and laryngoscopic abnormalities improved promptly after infliximab administration following an inadequate response to prednisolone. These cases underscore the importance of considering early anti-tumor necrosis factor-α therapy in steroid-refractory or relapsing laryngopharyngeal Behçet's syndrome, because progression to irreversible structural complications, including stenosis and adhesion, may necessitate surgical intervention if inflammation is not controlled before permanent damage occurs.","42429443":"ID: 42429443\nTitle: An Integrated Raman Platform with Embedded AI for Intraoperative Real-Time Cancer Detection.\nAbstract: Raman spectroscopy workflows are often fragmented across proprietary tools and ad hoc data-processing scripts, which slow decision-making and limit reproducibility and auditability. We present an integrated Raman platform with a Python-based GUI application that interfaces with the optical system(s) to unify instrument control, automate data acquisition, noise removal, signal processing, and run an embedded AI model for real-time classification of experimental samples. The system automatically archives intermediate and final outputs for auditability. We validated the platform's output for two types of experimental specimens: Tylenol and peritumoral biological samples from human laryngeal tissues. We compared the results with other studies, commercial software, and previous data-processing algorithms. The results obtained were consistent across all comparators. To demonstrate native analytics within the same workflow, we also developed and embedded a 1D convolutional neural network (CNN) tailored for biological Raman spectra. The multilayered CNN was trained on ex vivo human laryngeal tissue Raman spectra and was evaluated across 50 independent runs. The model achieved a mean test accuracy of 0.8929 ± 0.0213, a sensitivity of 0.9086 ± 0.0321, a specificity of 0.8698 ± 0.0434, and a mean AUC of 0.9506 ± 0.0142. The average latency across 50 runs was 2.82 s from signal acquisition to prediction, with device acquisition accounting for most of the time. The key innovation is not only the embedded AI but also an end-to-end, auditable workflow that unifies device control, acquisition, signal processing, visualization, and the archival of intermediate and final outputs, with optional real-time inference within a single platform.","42429483":"ID: 42429483\nTitle: YAP Regulates the Nrf2 Signaling Axis to Attenuate Oxidative Stress and Neuroinflammation in Retinal Ganglion Cell Degeneration.\nAbstract: Oxidative stress is a key driver of retinal ganglion cell (RGC) degeneration after optic nerve injury. Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.","42429600":"ID: 42429600\nTitle: Prekindergarten and Kindergarten Predictors of Reading Comprehension in Monolingual English and Spanish-English Bilingual Sixth Graders.\nAbstract: Poor reading comprehension performance by children in the United States is a continuing concern. Early identification and intervention can reduce the number of children with significant reading problems. We documented prekindergarten and kindergarten predictors of Grade 6 reading comprehension for English monolingual and Spanish-English bilingual groups and identified measures available to educators to flag children at risk for future reading comprehension problems. In Grade 6, children in the monolingual (n = 88) and bilingual (n = 95) groups completed a reading comprehension measure. These children were in a longitudinal study with previously completed code-related, vocabulary, grammar, listening comprehension, higher level language, working memory, and nonverbal IQ measures in prekindergarten and kindergarten. Data were analyzed separately by language group. We fit a series of Bayesian mixed-effects models incorporating prekindergarten and kindergarten measures as predictors. For the monolingual group, the most promising prekindergarten predictor was letter identification, and the most promising kindergarten predictors were vocabulary, grammar/morphology, and listening comprehension. For the bilingual group, the most promising prekindergarten predictors were English vocabulary, listening comprehension in Spanish, and memory updating in Spanish, and the most promising kindergarten predictor was English vocabulary. We suggest measures that could be administered in prekindergarten and kindergarten to flag students who may be at risk for future reading comprehension problems. We review other steps that schools and families may take to prevent reading comprehension problems. https://doi.org/10.23641/asha.32885270.","42429652":"ID: 42429652\nTitle: Parental Involvement, Gender Ideologies, and Socioeconomic Factors: Implications for Early Language Development in Preschool-Aged Children.\nAbstract: Research suggests that increased paternal involvement in childrearing has a positive effect on child development. However, there is a lack of knowledge about the role of fathers in their children's language development. The current study aimed to analyze the impact of parental involvement on language development of preschool children. It used a cross-sectional, correlational design to investigate the associations between parental involvement, particularly in language-promoting activities, and young children's language development, while also considering the role of parental gender ideologies and sociodemographic factors. Data were collected from 150 parents (fathers and mothers) and 80 children (average age of 47.35 ± 6.85 months), and two-family arrangements were compared. Parents completed extensive questionnaires, and children's linguistic skills were assessed using the European-Portuguese Preschool Language Assessment. The findings show that parental involvement, namely, reading to preschool children by both fathers and mothers, contributes significantly to their linguistic development, although in different ways. Parents with higher egalitarian gender ideologies tended to participate more actively in language stimulation activities. In addition, children from families with a more egalitarian division of parental tasks performed better in language development. Paternal and maternal involvement play a differentiating role in the language development of preschool children. These results reinforce the importance of promoting balanced parenting practices and programs that encourage the active participation of both parents from the early years of life, as well as the training of education and health care professionals, in order to value the role of the father in child development, contributing to richer contexts for child development.","42429676":"ID: 42429676\nTitle: A Survey of Speech-Language Pathologists' Current Clinical Practices in Setting Mastery Criteria.\nAbstract: Little is known about the mastery criteria that school-based speech-language pathologists (SLPs) select when writing therapeutic goals. This survey study aimed to document the criteria used, determine how data are collected by school-based SLPs, and examine the underlying reasons for the criteria used. This mixed-methods survey study recruited school-based SLPs in the United States via social media and e-mail to complete an online questionnaire of up to 16 items examining mastery criteria, data collection practices, and underlying rationales. Quantitative data were analyzed using descriptive statistics, and open-ended responses were analyzed using reflexive thematic analysis. One hundred twenty-five school-based SLPs completed the survey. The majority of respondents reported that they used a mastery criterion of 80% accuracy across three sessions. The most frequently cited reason was the belief that their chosen criteria would promote generalization and long-term retention. Trial-by-trial continuous data collection was the most common data collection method. Findings revealed a reliance on familiar mastery thresholds, despite emerging evidence supporting higher accuracy thresholds to promote skill maintenance and generalization. Some practices align with evidence, while others point to a need for better integration of empirical evidence into clinical decision making. https://doi.org/10.23641/asha.32677956.","42429678":"ID: 42429678\nTitle: From Foundations to Frontiers: Fit-for-Purpose Discourse Science.\nAbstract: This clinical focus article responds to discussions at the 2026 International Cognitive-Communication Disorders Conference (ICCDC), where participants highlighted a productive tension that has shaped discourse research for decades. Canonical discourse elicitation tasks (e.g., Cinderella retell) remain valuable because they support historical continuity, cross-study comparison, and shared data sets, yet they do not always capture the discourse constructs most relevant for all populations or clinical purposes. Discourse analysis has long been central to the assessment and treatment of neurogenic and cognitive-communication disorders, and canonical tasks have shaped decades of research by yielding replicable, analyzable, and linguistically rich language samples. This article is a narrative review that draws on the author's personal experience as a translational researcher and deep knowledge of the field. This article examines what canonical tasks revealed about language breakdown, why they succeeded within their original scope, where they may be inappropriate, and why and when they should still be retained. Building on discussion from the ICCDC, this piece argues that the field does not simply need \"new tasks\" but rather a principled framework for deciding when canonical tasks remain useful; when they should be adapted; and when new tasks, methods, and metrics are warranted. A fit-for-purpose discourse science is proposed, in which discourse tasks and outcome measures are selected because they are appropriate; robust; and aligned with the purpose, population, and construct of interest, while also integrating psychometric rigor, participatory design, and thoughtful use of technologies such as natural language processing and perceptual ratings. This clinical focus article also offers practical tables summarizing elicitation methods, suitable measures, key features of strong discourse assessment, clinically feasible implementation principles, and example scenarios for choosing canonical and noncanonical tasks in research and practice.","42429687":"ID: 42429687\nTitle: Readability of Patient-Reported Outcome Measures in Adult Speech-Language Pathology Practice.\nAbstract: Patient-reported outcome measures (PROMs) are widely used in adult speech-language pathology to capture patient- and caregiver-perceived symptoms, functional impact, and treatment outcomes. For PROM data to be valid and equitable, end users must be able to comprehend and complete these instruments as intended. This study evaluated the readability of validated English-language PROMs used in adult speech-language pathology practice and examined variability across clinical domains. Seventy-four validated adult speech-language pathology PROMs spanning eight clinical domains were identified from a recent scoping review and supplementary searches. Patient-facing text, including instructions, item stems, and response options, was extracted and analyzed using four readability indices: Flesch-Kincaid Grade Level, Coleman-Liau Index, Simple Measure of Gobbledygook (SMOG), and FORCAST Grade Level (FORCAST). Readability estimates were summarized descriptively and compared against a ≤ 6.0 grade-level benchmark for patient-facing health materials. Across PROMs and domains, readability estimates frequently exceeded recommended grade-level thresholds. No PROM met the ≤ 6.0 benchmark across all four indices. When averaged across indices, only a small subset of PROMs, primarily within the language and voice domains, met recommended readability levels. Domain-level averages generally exceeded the benchmark, particularly when assessed using SMOG and FORCAST. Validated PROMs used in adult speech-language pathology practice often require reading abilities above recommended health literacy levels, potentially limiting independent completion and equitable use. Readability should be considered alongside psychometric properties during PROM development, selection, and implementation to support accessible and patient-centered assessment.","42429739":"ID: 42429739\nTitle: Erratum to \"Temperament and Early Stuttering Development: Cross-Sectional Findings From a Community Cohort\".\nAbstract: ","42429768":"ID: 42429768\nTitle: Cross-Linguistic Perspectives on Aging and Sentence Processing: The Role of Word Order and Semantic Plausibility.\nAbstract: This cross-linguistic study investigates how healthy aging affects sentence comprehension across three typologically distinct languages-English (head-initial), Korean, and Japanese (both head-final). It explores how syntactic word order and semantic plausibility interact with aging and whether these effects differ across languages with varying structural characteristics. A total of 290 adults participated: 103 English speakers (49 younger, 54 older), 98 Korean speakers (50 younger, 48 older), and 89 Japanese speakers (43 younger, 46 older). All participants completed a sentence-picture matching task using auditorily presented stimuli. The sentences were systematically manipulated for semantic plausibility (plausible vs. less plausible) and word order, contrasting instrument-first (instrument-theme) and theme-first (theme-instrument) structures. Aging effects were observed across all languages, with older adults performing worse than younger adults. Across language groups, participants showed better performance for instrument-first sentences than for theme-first sentences. Semantic plausibility interacted significantly with age across all languages in both accuracy and response times, indicating that older adults were disproportionately affected by reduced plausibility. In contrast, word order effects were largely similar across age groups, although a significant Age Group × Word Order interaction was observed in response times for the Japanese participants only. This study demonstrates that systematic manipulations of simple sentence structures can effectively expose age-related and cross-linguistic differences in sentence processing. The findings illuminate both universal patterns of cognitive aging and language-specific parsing mechanisms, informing the design of sensitive and typologically flexible tools for assessing cognitive-linguistic decline.","42429770":"ID: 42429770\nTitle: Not So Simple, and Not So Fast: The Limits of Speech Rate and Turn-Taking Modifications for Treatment of Early Stuttering. A Response to Onslow et al.

We find that (a) the suggested approach is not new; (b) the limited pilot data are directly contradicted by a much larger scale, longer duration study published in this journal this year that shows no relationships between rate and turn-taking and recovery from stuttering; (c) rate and turn-taking adjustments may bring with them additional negative changes in parental speech; and (d) the proposed treatment continues to emphasize the role of parents in determining recovery from stuttering, a belief with insufficient evidence and which carries potential harm.","42429771":"ID: 42429771\nTitle: Clarifying Neuroplasticity Claims in Parent-Led Early Stuttering Intervention: A Response to Onslow et al. (2026).\nAbstract: Onslow et al. propose a simplified, parent-led early intervention for childhood stuttering based on reductions in parental speech rate and increased interturn pausing, framed within a neuroplasticity rationale for early treatment. While the goal of developing scalable and accessible interventions is important, the conceptual link between these conversational modifications and neuroplastic recovery warrants clarification. Neuroimaging studies in childhood stuttering have identified neural differences associated with persistence and recovery, but these findings establish correlates of developmental change rather than evidence that specific parental behaviors causally induce circuit-level reorganization. Established principles of experience-dependent plasticity indicate that durable neural change in speech motor systems typically requires high repetition, task specificity, and performance-contingent engagement of relevant neural networks. Current evidence is lacking regarding the potential behavioral benefits of parent-mediated conversational modifications, and further research is required to demonstrate that such strategies can induce neuroplastic mechanisms underlying recovery from stuttering. Distinguishing between environmental modulation, short-term fluency facilitation, and neural causation is important to support mechanistic claims. I suggest that future research evaluate simplified parent-led interventions through adequately powered randomized trials and, where possible, incorporate longitudinal neural measures to determine whether behavioral improvements are associated with measurable changes in speech motor circuitry.","42429772":"ID: 42429772\nTitle: Response to the Letters by Chang and Bernstein Ratner.\nAbstract: In our original article, we draw attention to the lifetime quality-of-life impairment that can result from childhood stuttering-hence, the need for immediate intervention after onset. We drew on existing experimental outcomes that parent speech-rate reduction and increased interturn speaker latency may reduce stuttering. We developed a two-factor treatment protocol based on those variables in combination and showed its clinical viability, suggesting that it would be a suitable target for Phase I-IV clinical trials. Chang and Bernstein Ratner wrote letters to the editor on our article, to which we respond. Our response to these letters to the editor covers the following issues raised by Chang and Bernstein Ratner: mechanisms of action for the proposed treatment, the evidence base for the treatment, plans to explore its treatment effects, and the need to verify its safety.","42429793":"ID: 42429793\nTitle: From Hate Speech to Justice Beliefs: A Serial Mediation Model Linking Victimization, School Climate, and Adolescents' Personal Belief in a Just World.\nAbstract: Victimization through hate speech represents identity-based violence during adolescence and is negatively related to core beliefs about justice. However, there is limited information on how exposure to hate speech leads to changes in an adolescent's Personal Belief in a Just World (PBJW). This study used the frameworks of Trauma Theory and Just World Theory to examine a serial mediation model in which victimization through hate speech was expected to lead indirectly to lower PBJW through perceived unsafety at school and decreased school well-being. A sample of 1,108 adolescents (Mage = 15.59; 61% female) in Italy completed self-report measures of victimization through hate speech, perceived school unsafety, school well-being, and PBJW. Results obtained using PROCESS Model 6 with 5,000 bootstrap samples indicated a significant indirect relationship: exposure to hate speech was associated with greater perceptions of unsafety in the school environment, which in turn were associated with lower levels of school well-being and lower PBJW. The direct effect of hate speech on PBJW was not significant, suggesting that the psychological impact of hate speech is primarily a result of how adolescents experience changes in their school environment on a daily basis. These results illustrate the cognitive pathway through which exposure to hate speech may contribute to adolescents' internalization of personal justice beliefs. This study advances understanding of the associations among hate speech victimization, school climate perceptions, and adolescents' personal beliefs about justice by identifying a theoretically derived pathway linking these constructs.","42429808":"ID: 42429808\nTitle: Digital Resurrection in ACP: Neurodegeneration, Relational Dying, and the Limits of Simulated Presence.\nAbstract: ","42429841":"ID: 42429841\nTitle: Re: Effects of resistance training with/without photobiomodulation on muscle and respiratory function in difficult-to-control asthma: a randomized trial.\nAbstract: This letter discusses Costa et al.'s randomized trial of resistance training (RT) combined with photobiomodulation therapy (PBMT) for difficult-to-control asthma (DTCA). The triple-blind study shows RT+PBMT safely improves peripheral muscle strength and exercise capacity better than RT alone. PBMT has dose-dependent effects, but optimal parameters for chronic respiratory patients remain unclear. Some clinicians have proposed standalone PBMT for DTCA patients unable to complete resistance training, but this approach has not been validated in clinical trials. The absence of a PBMT-only group limits assessment for patients unable to tolerate RT. The intervention did not improve lung function or asthma control, acting only peripherally. RT+PBMT is a useful adjuvant therapy; future studies should optimize PBMT dosing, test standalone PBMT, and examine long-term outcomes, and compare different PBMT wavelengths, energy settings and irradiation sites to refine real-world treatment protocols.","42429860":"ID: 42429860\nTitle: Human iPSC-Derived Spinal Neurons Carrying the ALS FUS (P525L) Mutation Exhibit Lower Response to Inhibitory Neurotransmitters.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder characterized by motoneurons degeneration. Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the α1 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.","42429951":"ID: 42429951\nTitle: [Choroidal folds as a diagnostic indication for a posterior mass of unknown etiology].\nAbstract: A 59-year-old woman presented with a four-month history of progressive visual loss and floaters in her left eye. Her medical history included hypothyroidism, psoriasis, and type 2 diabetes. Fundus examination revealed choroidal folds, an amelanotic lesion temporal to the fovea, and an exudative retinal detachment. Optical coherence tomography (OCT) demonstrated a choroidal mass without subretinal fluid, while indocyanine green angiography (ICGA) showed a hypocyanescent lesion with no intrinsic vascularity. B-scan ultrasonography revealed an inhomogeneous choroidal mass with retrobulbar fluid (positive T-sign). Blood tests revealed elevated C-reactive protein (CRP) and liver enzymes levels, together with positive antinuclear antibodies (ANA), while the chest X-ray was normal. The overall clinical and imaging findings were consistent with nodular granulomatous scleritis. Choroidal melanoma, uveal lymphoma, primary vitreoretinal lymphoma, and choroidal hemangioma were excluded based on their imaging characteristics. Treatment with systemic corticosteroids resulted in rapid visual improvement and complete resolution of the lesion. This case demonstrates how inflammatory choroidal lesions can mimic intraocular tumors. Recognizing characteristic multimodal imaging features (choroidal folds, preserved choroidal vasculature on ICGA, positive T-sign on ultrasonography) can enable a confident diagnosis without biopsy, avoiding unnecessary treatment and delays in cancer diagnosis.

Patients with OSA were identified using ICD-10 code G47.33 in the TriNetX Research Network, and those who had not undergone polysomnography were excluded. The prevalence of dysphagia (ICD-10 R13.1) and associated sequelae, including aspiration pneumonia (ICD-10 J69.0), was evaluated. Swallowing assessments were captured using CPT codes for clinical and instrumental evaluations. Of 1,328,355 patients with OSA, 15% had a documented diagnosis of dysphagia. The majority were coded with unspecified dysphagia (85%), followed by oropharyngeal dysphagia (21%). Sequelae of dysphagia, including aspiration pneumonia, malnutrition, and gastrotomy tube dependence, were seen in 19.1% of patients with both OSA and dysphagia. Despite this, only 29.56% of dysphagic patients underwent formal swallowing assessment. Specifically, 20.53% received a videofluoroscopic swallow study (VFSS) and 1.55% underwent flexible endoscopic evaluation of swallowing (FEES). Diagnostic yield varied by modality: 77.1% of patients undergoing instrumental evaluation were diagnosed with dysphagia, compared to 29.0% with clinical evaluation alone. Dysphagia is underrecognized in patients with OSA, with most diagnoses made without formal assessment despite substantial aspiration risk. Instrumental evaluations significantly improve diagnostic accuracy but remain underutilized. These findings highlight the need for standardized, multidisciplinary screening protocols to improve the detection and management of dysphagia in the OSA population.","42430044":"ID: 42430044\nTitle: Natural intoxication by Solanum bonariense causing cerebellar neurodegeneration in cattle in Argentina.\nAbstract: Solanum bonariense is a perennial shrub widely distributed in South America and has also been introduced into other regions, including parts of Europe and North Africa. Its consumption has been associated with chronic neurodegenerative disease in grazing cattle, although well-documented natural cases remain limited, particularly those integrating clinical, epidemiological, and advanced pathological findings. This study provides a comprehensive characterization of a natural outbreak of S. bonariense intoxication in cattle under field conditions. The outbreak was observed on a beef cattle farm located on an island of the Paraná River Delta, Buenos Aires Province, Argentina, during a prolonged drought that resulted in severe forage scarcity. Neurological disease affected 20 of 76 (26%) adult Aberdeen Angus cows, with a high lethality (75%). Clinically, the affected animals exhibited recurrent, episodic neurological signs characterized by abnormal gait (ataxia, hypermetria), postural instability, muscle tremors, frequent falls, and, during recovery, occasional dog-sitting posture and stargazing, with no loss of consciousness. Postmortem examination was conducted in an affected cow; no gross lesions were observed. Histopathological examination revealed marked vacuolar degeneration, death and loss of Purkinje neurons in the cerebellum, with axonal and dendritic spheroids, and secondary demyelination. Prominent reactive cerebellar astrogliosis was demonstrated by immunofluorescence with anti-glial fibrillary acidic protein. Ultrastructural analysis demonstrated numerous membrane-bound intracytoplasmic vesicles containing electron-dense material, consistent with dilated lysosomes in Purkinje neurons. Abundant S. bonariense was botanically identified in the paddocks the affected animals grazed on for nearly 8 months. The epidemiological context, characteristic clinical presentation, and distinctive neuropathological findings support a diagnosis of chronic plant-induced cerebellar neurodegeneration. By integrating field epidemiology with detailed histopathological, ultrastructural, and immunofluorescence data, this study complements previous experimental and sporadic reports and contributes to improved recognition, differential diagnosis, and understanding of the pathogenesis of S. bonariense intoxication in diverse production systems.","42430091":"ID: 42430091\nTitle: The Role of PGC-1α in Neurodegenerative Diseases: Molecular Mechanisms, Translational Challenges, and Therapeutic Potential.\nAbstract: Neurodegenerative diseases (NDDs) are progressive disorders in which mitochondrial dysfunction, oxidative stress, proteostasis failure, neuroinflammation, and synaptic damage progressively interact to drive neuronal vulnerability. Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) links metabolic adaptation to stress-response pathways that are repeatedly disrupted in Alzheimer's disease, Parkinson's disease, Huntington's disease, polyglutamine (PolyQ) disorders, and amyotrophic lateral sclerosis. Rather than providing only an updated catalogue of studies, this review organizes the evidence into a cross-disease rheostat framework that explains why PGC-1α modulation is protective in some settings but incomplete or maladaptive in others. Current findings indicate that PGC-1α supports mitochondrial biogenesis, oxidative phosphorylation, antioxidant defense, mitophagy, autophagy, protein quality control, and inflammatory balance. However, its effects are highly context dependent. In several models, restoration of PGC-1α-related signaling improves mitochondrial function and reduces neuronal injury, whereas broad, sustained, or cell-inappropriate activation may produce limited benefit or undesirable outcomes. These observations suggest that PGC-1α is not a simple neuroprotective switch, but a flexible regulatory hub whose therapeutic value depends on cell type, isoform profile, disease stage, and activation level. Emerging strategies, including small-molecule modulators, gene delivery, antisense-based approaches, nanoparticle systems, and exercise-related interventions, remain largely preclinical and face major barriers related to CNS delivery, pathway selectivity, dose and cell-type control, peripheral safety, and validated target-engagement biomarkers. Nevertheless, clinical translation requires stronger causal validation, reliable target-engagement biomarkers, selective delivery methods, and long-term safety assessment. Future research should focus on precision-based modulation of PGC-1α to determine when and how this pathway can be safely used for disease modification. Such a careful approach may help transform PGC-1α from a broad experimental target into a clinically relevant strategy for well-defined neurodegenerative phenotypes."},"globalTags":{"choroid":1,"multimodal imaging":1,"scleritis":1,"tumor":1,"uveitis":1,"excitotoxicity":1,"glycinergic transmission":1,"inhibitory/excitatory
