The neurobiological mechanisms involved remain unclear. We investigated the role of wake-promoting Orexin (Ox) and Histamine (HA) neurons in SIDS. Cerebrospinal fluid (CSF) Ox levels were measured in 61 living controls and 70 Sudden Unexpected Death Infants (SUDI: 38 SIDS, 32 explained deaths (ED)). HA and tele-methylhistamine (t-MeHA) were analyzed in an additional 46 SUDI (34 SIDS, 12 ED) and 42 controls. Immunohistochemistry was performed on hypothalamic tissue from 11 SIDS and 8 ED cases to quantify Ox and HA neuron numbers. CSF Ox levels did not differ overall between groups but were higher in SUDI infants aged 2-6 months. HA and t-MeHA levels were elevated in SUDI, likely reflecting postmortem release. Ox neuron numbers were increased in rostral hypothalamic region in SIDS compared with EDs, whereas HA neuron numbers were unchanged. SIDS is associated with increased Ox neuronal activity during the peak risk period, possibly reflecting a homeostatic upregulation in response to arousal deficit or repeated stress or hypoxia, while the role\u00a0of\u00a0HA system remains to be clarified with more sensitive biomarkers. First study evaluating orexin and histamine systems in SIDS using CSF and postmortem brain tissue. Identifies elevated orexin activity in SIDS infants, particularly in the 2-6 month risk window.

During the pandemic period, an increase in the incidence of Sudden Unexpected Infant Death (SUID) and Sudden Infant Death Syndrome (SIDS) was observed. Currently, their rates remain elevated compared to the prepandemic period. The pathogenetic mechanisms underlying the fulminant course of infection in infants leading to fatal outcomes remain insufficiently understood. In this study, we report for the first time the results of histological and immunohistochemical examination of the lungs in a case of COVID-19-associated SUID in a 2-month-old infant. The absence of similar studies in the available literature limits opportunities for analyzing the pathogenesis of SUID. Our data allow a detailed characterization of the histological changes in the lungs, the localization and range of SARS-CoV-2 nucleocapsid protein expression, the identification of molecular mechanisms underlying apoptosis in the pulmonary microvascular endothelium, and the elucidation of the role of endothelial dysfunction. Particular attention in this article is devoted to the role of cytokines (IL-6, TNF-\u03b1, and IFN-\u03b3) in the pathogenesis of hyperacute viral infection. The obtained data demonstrate substantial differences between the observed changes and the classic presentation of COVID-19 in older children. These findings offer prospects for improving prevention strategies and developing targeted therapy for fulminant forms of COVID-19, while also contributing to the understanding of SIDS pathogenesis."

As in other developed countries, Australian SUDI rates are relatively low, but incidence rates have remained essentially unchanged since 2004. To increase our understanding of these deaths, we reviewed a cohort of SUDI cases with positive hair toxicology, focussing on toxicology results, pathology findings, and SIDS risk factors.\u00a0All infant deaths between 1st January 2014 and 31st of December 2023 with positive hair toxicology in the state of Victoria, Australia, were reviewed for toxicology results, pathology findings and SIDS risk factors.\u00a0A total of 99 infant deaths met the selection criteria. At least one SIDS risk factor was reported in every case, with a median of 5 per case, highlighting that these infants likely had a high cumulative risk for SIDS. Co-sleeping was most common, reported in over 75% of cases. Polysubstance use was high (87%), with a median of 4 drugs detected per case. Methylamphetamine was detected in hair in over half of cases (n\u2009=\u200957, 58%). Postmortem findings including serious illnesses, like pneumonia (p\u2009=\u20090.002), significant neuropathology (p\u2009=\u20090.002 and p\u2009=\u20090.035), low head circumference (<\u200915th percentile) (p\u2009=\u20090.035) and low body weight (<\u200915th percentile) (p\u2009=\u20090.022 and p\u2009=\u20090.011) were all positively correlated with drug exposure in hair.\u00a0Infants with positive hair toxicology appear to have a high cumulative risk for SIDS, which may reflect a chaotic home environment. Most postmortem findings were positively correlated with drug exposure."

"abstract_text": "ID: 42003135\nTitle: A motor thalamic site in humans that suppresses involuntary breathing without awareness.\nAbstract: Breathing is generated by brainstem respiratory networks but can be controlled and modulated by forebrain activity. The recent clinical adoption of thalamic electrode implantation during intracranial electroencephalography (iEEG) provides a rare opportunity to examine the role of the human thalamus in respiratory control. Here, we tested whether thalamic stimulation alters breathing in 11 patients undergoing iEEG for epilepsy monitoring. Across 412 stimulation trials at 108 thalamic sites, thalamic stimulation induced central apnea in every participant. Apnea occurred in isolation without sensory or motor effects and without awareness of breathing cessation. Apnea occurred with stimulation of either the right or left thalamus and was observed across all ages, including participants as young as 22 mo. Volitional breathing and speech were preserved, indicating that respiratory motor pathways remained functional. In contrast, except for the amygdala, stimulation of other forebrain regions, including the hippocampus, insula, cingulate, and frontal, temporal, and parietal cortices, did not affect breathing. Respiratory inhibition depended on thalamic location, occurring most consistently with stimulation of the ventral lateral anterior (VLa) and ventral anterior (VA) nuclei. A machine learning algorithm localized the focal apneic region within the anterior motor thalamus, centered in VLa and extending into VA. Identification of a focal apneic site in the VLa/VA motor thalamus expands thalamic function, revealing a forebrain node capable of overriding brainstem respiratory control. This circuit may coordinate breathing with volitional behaviors such as speech, and dysfunction of this circuit may play a role in central apnea disorders, including sleep apnea, SUDEP, and SIDS.NEW & NOTEWORTHY This study identifies a focal site in the human motor thalamus where electrical stimulation suppresses involuntary, automatic breathing and induces apnea without awareness. Using intracranial recordings in pediatric and adult patients, we found that this effect localizes to the ventral anterior/ventral lateral anterior nuclei. These findings reveal a previously unrecognized thalamic function in the forebrain control of breathing."

However, maternal anxiety may influence how effectively this awareness translates into confident caregiving. Parenting self-efficacy is a determinant of maternal behavior, yet the mechanisms linking SIDS awareness and self-efficacy remain unclear. To examine the relationship between SIDS awareness and parenting self-efficacy among mothers of infants and to investigate the mediating role of maternal anxiety. A cross-sectional study was conducted among 335 mothers of infants aged 0-12\u00a0months attending six primary healthcare facilities in Mansoura, Egypt. Data were collected using validated scales that measure SIDS awareness, postpartum anxiety, and parenting self-efficacy. Pearson correlations, mediation analysis, and multiple linear regression were performed. SIDS awareness was positively associated with parenting self-efficacy (r\u00a0=\u00a00.57, p\u00a0<\u00a00.001) and negatively associated with maternal anxiety (r\u00a0=\u00a0-0.18, p\u00a0<\u00a00.001). Anxiety was inversely related to self-efficacy (r\u00a0=\u00a0-0.31, p\u00a0<\u00a00.001). Mediation analysis revealed that maternal anxiety partially mediated the relationship between SIDS awareness and parenting self-efficacy. Nurse-led care should combine safe sleep education with routine screening and management of maternal anxiety. Reassurance-focused communication and brief psychosocial support during postnatal visits may strengthen maternal confidence and improve adherence to safe infant care practices. Maternal anxiety partially shapes how SIDS awareness influences parenting self-efficacy. Integrating emotional support with SIDS education may strengthen maternal confidence and improve safe infant care practices."

Reelin, an extracellular matrix protein, is critical in neuronal migration and cell positioning. An altered reelin expression is hypothesized as a contributor to altered DG morphology. This study aimed to determine whether the number of reelin-expressing cells within the infant hippocampus is altered in (1) SIDS, and according to the presence of (2) SIDS risk factors (age, cigarette smoke exposure [CSE], sleep position, bed sharing, and upper respiratory tract infection [URTI]), and (3) DG morphology. Immunohistochemical staining of reelin was quantified (measured as the number of positive reelin cells/mm2) within the layers of the DG, CA4/Hilus, CA3-CA1, and subiculum in cases of explained SUDI (eSUDI, n\u2009=\u200912), SIDS I (n\u2009=\u20097), and SIDS II (n\u2009=\u200933). Reelin was highly correlated with age. After adjusting for age, SIDS II infants had a lower number of reelin immunopositive cells in the CA1, a finding that was more pronounced in bed sharers. Analysis of risk factors indicated lower reelin in the DG and CA3 of males, and in the DG of infants with URTI (when excluding bed sharers). The presence of the DG morphological feature of cluster ectopic cells was associated with a lower number of reelin cells across several hippocampal layers, whereas gaps were associated with higher numbers, with layers predominantly affected being the DG molecular layer and CA2 stratum radiatum."

In a retrospective cohort, patient records from 483\u2009284 infants born in Stockholm, Sweden, between 2002 and 2022 were screened for SUPC-related diagnoses. SUPC was defined as a collapse within the first 7\u2009days of life in near-term infants with good postnatal adaptation. Maternal, infant and event characteristics were collected. Urine was analysed for prostaglandin E2 (PGE2) metabolites in a subgroup of cases. We identified 149 cases of SUPC, corresponding to an incidence of 31 per 100\u2009000 live births, exceeding that of early onset sepsis caused by Group B Streptococcus. Half the SUPC cases occurred during the first four postnatal hours. The mortality was 7% and 26% suffered from neurological sequelae. The highest risk of SUPC coincided with the postnatal peak in PGE2 levels. All newborn infants were at risk of SUPC, especially within 24\u2009h of birth. SUPC was associated with early unsupervised skin-to-skin care and bed sharing. Guidelines promoting safe sleep and skin-to-skin care should be implemented to prevent SUPC and save the lives of newborn babies."

Single-center, retrospective study with SUDI cases included by a French SUDI referral center in the French national registry for SUDI cases between 2017 and 2025. All available PMFP, the final diagnosis and the post-mortem interval between death and PMFP were collected.

The mean age at death was 4.5\u00a0\u00b1\u00a04.9\u00a0months, 30 children were male (65%). The main PMFP features were retinal changes resembling central retinal artery occlusion and macular and/or peripheral white radial retinal folds. The presence of a macular fold was associated with a longer post-mortem interval (presence versus absence of a macular fold: 12.2\u00a0\u00b1\u00a07.2\u00a0h [range: 4-30] versus 4.5\u00a0\u00b1\u00a01.6\u00a0h [range: 3-9], p\u00a0<\u00a00.001). Retinal hemorrhages were found in four non-abusive cases with non-specific fundus features and in two confirmed AHT cases, with AHT-suggestive features. The normal post-mortem fundus in children under two years old shows a \"central retinal artery occlusion\" pattern, followed by the appearance of macular or peripheral white radial retinal folds, that should not be mistaken for circumferential perimacular retinal folds and hemorrhagic retinoschisis cavities that have been described in AHT cases.

It may be particularly important in global health research, where funding inequities and under-representation of local expertise in peer-reviewed research articles-often published by commercial publishers for substantial fees-can lead to evidence gaps in systematic reviews. However, searching, reporting and analysing grey literature poses conceptual and methodological challenges. We conducted a systematic scoping review of commercially published and grey literature examining food sources in Small Island Developing States (SIDS). The grey literature component aimed to expand understanding beyond built food environments and food retail and to promote epistemic justice by including traditionally excluded voices, knowledge and experiences. This might be especially important in SIDS, which, due to their small size, remote locations and limited global visibility, might not be well represented in commercially published literature. In this paper, we discuss how grey literature enriched our findings, offering detailed descriptions of diverse food sources, regional data and country comparisons less present in commercially published sources. These documents frequently reflected multisectoral initiatives and were developed through partnerships involving local stakeholders. Beyond highlighting the value of grey literature, we also provide practical guidance for its use in evidence synthesis. This includes key principles for effective searching and screening to support researchers aiming to incorporate grey literature in a systematic and transparent way. Our findings underline the importance of including grey literature to avoid excluding valuable perspectives and perpetuating structural imbalances in global health knowledge."

Reserve varies with developmental ontogeny, genotype, and acquired suppression (e.g., cytokine-mediated phenoconversion). Early infancy represents a developmental window in which clearance capacity and redox/energetic buffering may be comparatively constrained. We introduce a hypothesis-generating Three-Axis Convergence Framework (TCF) modeling interacting effects of (i) developmental/genetic reserve limits, (ii) immune-cytokine modulation of metabolism, and (iii) exposure/disposition context, and translate this synthesis into a structured postmortem interpretive tool integrated into the primary medicolegal autopsy, using an enhanced analytic panel applied selectively based on case context and specimen validity/QC to support mechanistic characterization of infant deaths remaining unexplained (often SUID/SIDS). A structured narrative synthesis was conducted spanning developmental pharmacology, pharmacogenetics, immunology, redox biology, neuropathology, and toxicology. Routine medicolegal postmortem practices used in SUID investigations were reviewed to identify measurement gaps that may limit mechanistic resolution in unexplained cases. The synthesis was formalized into five analytic domains: CYP450 capacity, immune/cytokine load, redox balance/energetics, neurochemical integrity, and xenobiotic/metal burden. The Metabolic Vulnerability Index (MVI) operationalizes the TCF as a five-domain ordinal scoring system (0-15). Domain 1 is anchored by hepatic CYP protein abundance (a more postmortem-stable proxy than CYP activity assays, which are generally constrained by rapid functional decay and QC limitations), normalized to adult reference and interpreted against age-matched developmental expectations. Domain-combination lookup tables route users to 14 mechanistically defined archetypes and specify modifier/exposure-context documentation. Appendices define an operational postmortem workflow, specimen validity rules, analytic QC constraints, detection limits, and a worked example. A Cytokine-Metabolic Suppression Profile (CMSP) is presented as an interpretive coherence summary and does not modify MVI scoring or certification. The MVI provides a structured framework for describing multidomain physiologic constraints in unexplained infant deaths alongside standard forensic practice. In this way, the TCF, MVI, and CMSP together offer a disciplined response to long-standing mechanistic uncertainty in early life-by enabling systematic measurement, coherent interpretation, and transparent identification of evidence gaps, rather than asserting new causes."

The neurobiological mechanisms involved remain unclear. We investigated the role of wake-promoting Orexin (Ox) and Histamine (HA) neurons in SIDS. Cerebrospinal fluid (CSF) Ox levels were measured in 61 living controls and 70 Sudden Unexpected Death Infants (SUDI: 38 SIDS, 32 explained deaths (ED)). HA and tele-methylhistamine (t-MeHA) were analyzed in an additional 46 SUDI (34 SIDS, 12 ED) and 42 controls. Immunohistochemistry was performed on hypothalamic tissue from 11 SIDS and 8 ED cases to quantify Ox and HA neuron numbers. CSF Ox levels did not differ overall between groups but were higher in SUDI infants aged 2-6 months. HA and t-MeHA levels were elevated in SUDI, likely reflecting postmortem release. Ox neuron numbers were increased in rostral hypothalamic region in SIDS compared with EDs, whereas HA neuron numbers were unchanged. SIDS is associated with increased Ox neuronal activity during the peak risk period, possibly reflecting a homeostatic upregulation in response to arousal deficit or repeated stress or hypoxia, while the role\u00a0of\u00a0HA system remains to be clarified with more sensitive biomarkers. First study evaluating orexin and histamine systems in SIDS using CSF and postmortem brain tissue. Identifies elevated orexin activity in SIDS infants, particularly in the 2-6 month risk window. No evidence to date for direct histamine involvement; need for more sensitive biomarkers. Suggests orexin system as a potential biomarker for SIDS risk stratification. Highlights the importance of combined neurobiological approaches for prevention."

"abstract_text": "ID: 42003135\nTitle: A motor thalamic site in humans that suppresses involuntary breathing without awareness.\nAbstract: Breathing is generated by brainstem respiratory networks but can be controlled and modulated by forebrain activity. The recent clinical adoption of thalamic electrode implantation during intracranial electroencephalography (iEEG) provides a rare opportunity to examine the role of the human thalamus in respiratory control. Here, we tested whether thalamic stimulation alters breathing in 11 patients undergoing iEEG for epilepsy monitoring. Across 412 stimulation trials at 108 thalamic sites, thalamic stimulation induced central apnea in every participant. Apnea occurred in isolation without sensory or motor effects and without awareness of breathing cessation. Apnea occurred with stimulation of either the right or left thalamus and was observed across all ages, including participants as young as 22 mo. Volitional breathing and speech were preserved, indicating that respiratory motor pathways remained functional. In contrast, except for the amygdala, stimulation of other forebrain regions, including the hippocampus, insula, cingulate, and frontal, temporal, and parietal cortices, did not affect breathing. Respiratory inhibition depended on thalamic location, occurring most consistently with stimulation of the ventral lateral anterior (VLa) and ventral anterior (VA) nuclei. A machine learning algorithm localized the focal apneic region within the anterior motor thalamus, centered in VLa and extending into VA. Identification of a focal apneic site in the VLa/VA motor thalamus expands thalamic function, revealing a forebrain node capable of overriding brainstem respiratory control. This circuit may coordinate breathing with volitional behaviors such as speech, and dysfunction of this circuit may play a role in central apnea disorders, including sleep apnea, SUDEP, and SIDS.NEW & NOTEWORTHY This study identifies a focal site in the human motor thalamus where electrical stimulation suppresses involuntary, automatic breathing and induces apnea without awareness. Using intracranial recordings in pediatric and adult patients, we found that this effect localizes to the ventral anterior/ventral lateral anterior nuclei. These findings reveal a previously unrecognized thalamic function in the forebrain control of breathing."

Reelin, an extracellular matrix protein, is critical in neuronal migration and cell positioning. An altered reelin expression is hypothesized as a contributor to altered DG morphology. This study aimed to determine whether the number of reelin-expressing cells within the infant hippocampus is altered in (1) SIDS, and according to the presence of (2) SIDS risk factors (age, cigarette smoke exposure [CSE], sleep position, bed sharing, and upper respiratory tract infection [URTI]), and (3) DG morphology. Immunohistochemical staining of reelin was quantified (measured as the number of positive reelin cells/mm2) within the layers of the DG, CA4/Hilus, CA3-CA1, and subiculum in cases of explained SUDI (eSUDI, n\u2009=\u200912), SIDS I (n\u2009=\u20097), and SIDS II (n\u2009=\u200933).

Analysis of risk factors indicated lower reelin in the DG and CA3 of males, and in the DG of infants with URTI (when excluding bed sharers). The presence of the DG morphological feature of cluster ectopic cells was associated with a lower number of reelin cells across several hippocampal layers, whereas gaps were associated with higher numbers, with layers predominantly affected being the DG molecular layer and CA2 stratum radiatum."

Our data allow a detailed characterization of the histological changes in the lungs, the localization and range of SARS-CoV-2 nucleocapsid protein expression, the identification of molecular mechanisms underlying apoptosis in the pulmonary microvascular endothelium, and the elucidation of the role of endothelial dysfunction. Particular attention in this article is devoted to the role of cytokines (IL-6, TNF-\u03b1, and IFN-\u03b3) in the pathogenesis of hyperacute viral infection. The obtained data demonstrate substantial differences between the observed changes and the classic presentation of COVID-19 in older children. These findings offer prospects for improving prevention strategies and developing targeted therapy for fulminant forms of COVID-19, while also contributing to the understanding of SIDS pathogenesis."

Single-center, retrospective study with SUDI cases included by a French SUDI referral center in the French national registry for SUDI cases between 2017 and 2025. All available PMFP, the final diagnosis and the post-mortem interval between death and PMFP were collected. Of the 78 SUDI cases recorded in Nantes, 65 underwent a fundus examination, of which 46 had PMFP available. The mean age at death was 4.5\u00a0\u00b1\u00a04.9\u00a0months, 30 children were male (65%). The main PMFP features were retinal changes resembling central retinal artery occlusion and macular and/or peripheral white radial retinal folds. The presence of a macular fold was associated with a longer post-mortem interval (presence versus absence of a macular fold: 12.2\u00a0\u00b1\u00a07.2\u00a0h [range: 4-30] versus 4.5\u00a0\u00b1\u00a01.6\u00a0h [range: 3-9], p\u00a0<\u00a00.001). Retinal hemorrhages were found in four non-abusive cases with non-specific fundus features and in two confirmed AHT cases, with AHT-suggestive features. The normal post-mortem fundus in children under two years old shows a \"central retinal artery occlusion\" pattern, followed by the appearance of macular or peripheral white radial retinal folds, that should not be mistaken for circumferential perimacular retinal folds and hemorrhagic retinoschisis cavities that have been described in AHT cases. PMFP allow detecting and documenting retinal hemorrhages, which may be indicative of infanticide."

It may be particularly important in global health research, where funding inequities and under-representation of local expertise in peer-reviewed research articles-often published by commercial publishers for substantial fees-can lead to evidence gaps in systematic reviews. However, searching, reporting and analysing grey literature poses conceptual and methodological challenges. We conducted a systematic scoping review of commercially published and grey literature examining food sources in Small Island Developing States (SIDS). The grey literature component aimed to expand understanding beyond built food environments and food retail and to promote epistemic justice by including traditionally excluded voices, knowledge and experiences. This might be especially important in SIDS, which, due to their small size, remote locations and limited global visibility, might not be well represented in commercially published literature. In this paper, we discuss how grey literature enriched our findings, offering detailed descriptions of diverse food sources, regional data and country comparisons less present in commercially published sources. These documents frequently reflected multisectoral initiatives and were developed through partnerships involving local stakeholders. Beyond highlighting the value of grey literature, we also provide practical guidance for its use in evidence synthesis. This includes key principles for effective searching and screening to support researchers aiming to incorporate grey literature in a systematic and transparent way. Our findings underline the importance of including grey literature to avoid excluding valuable perspectives and perpetuating structural imbalances in global health knowledge."

"abstract_text": "ID: 41938522\nTitle: CYP450 Constraints in Infants: A Multidomain Convergence Framework for Investigating Mechanistic Vulnerability.\nAbstract: Cytochrome P450 (CYP450) enzymes are the primary hepatic Phase I oxidative biotransformation system for many drugs and xenobiotics; variability in CYP capacity is therefore a key determinant of metabolic reserve. Reserve varies with developmental ontogeny, genotype, and acquired suppression (e.g., cytokine-mediated phenoconversion). Early infancy represents a developmental window in which clearance capacity and redox/energetic buffering may be comparatively constrained. We introduce a hypothesis-generating Three-Axis Convergence Framework (TCF) modeling interacting effects of (i) developmental/genetic reserve limits, (ii) immune-cytokine modulation of metabolism, and (iii) exposure/disposition context, and translate this synthesis into a structured postmortem interpretive tool integrated into the primary medicolegal autopsy, using an enhanced analytic panel applied selectively based on case context and specimen validity/QC to support mechanistic characterization of infant deaths remaining unexplained (often SUID/SIDS). A structured narrative synthesis was conducted spanning developmental pharmacology, pharmacogenetics, immunology, redox biology, neuropathology, and toxicology. Routine medicolegal postmortem practices used in SUID investigations were reviewed to identify measurement gaps that may limit mechanistic resolution in unexplained cases. The synthesis was formalized into five analytic domains: CYP450 capacity, immune/cytokine load, redox balance/energetics, neurochemical integrity, and xenobiotic/metal burden. The Metabolic Vulnerability Index (MVI) operationalizes the TCF as a five-domain ordinal scoring system (0-15). Domain 1 is anchored by hepatic CYP protein abundance (a more postmortem-stable proxy than CYP activity assays, which are generally constrained by rapid functional decay and QC limitations), normalized to adult reference and interpreted against age-matched developmental expectations. Domain-combination lookup tables route users to 14 mechanistically defined archetypes and specify modifier/exposure-context documentation. Appendices define an operational postmortem workflow, specimen validity rules, analytic QC constraints, detection limits, and a worked example. A Cytokine-Metabolic Suppression Profile (CMSP) is presented as an interpretive coherence summary and does not modify MVI scoring or certification. The MVI provides a structured framework for describing multidomain physiologic constraints in unexplained infant deaths alongside standard forensic practice. In this way, the TCF, MVI, and CMSP together offer a disciplined response to long-standing mechanistic uncertainty in early life-by enabling systematic measurement, coherent interpretation, and transparent identification of evidence gaps, rather than asserting new causes."

To better understand early human islet cell development and maturation, we collected 123 pediatric pancreata and mapped morphological and spatiotemporal changes from birth through the first ten years of life. Using quantitative analyses and a combination of complementary tissue imaging approaches, including confocal microscopy and whole-slide multiplex imaging, we developed an integrated model for endocrine cell formation and islet architecture, including endocrine cell type heterogeneity and abundance, endocrine cell proliferation, and islet vascularization and innervation. We also assessed insulin and glucagon secretory profiles in isolated islet preparations from pediatric donors aged 2 months to 10 years and found a temporal difference in the maturation of insulin secretion compared to glucagon secretion.

In neonatal intensive care units (NICUs), ambient noise frequently exceeds recommended thresholds and may interfere with auditory and neurodevelopmental maturation. During a critical period of sensory refinement, infants are exposed to unpredictable, high-intensity soundscapes generated by alarms, respiratory devices, and staff activity, contrasting sharply with the regulated acoustic environment of the womb. This systematic review aimed to identify, describe, and categorize noise sources in the NICU and to examine their potential impact on preterm infants. A systematic search across six major databases [MEDLINE, Embase, APA Psychinfo, CINHAL, Scopus, Web of Science (WOS); 2000-2026] identified studies reporting 24-h noise levels, day-night variation, and differences between incubator-internal and external sound. Eligible studies were synthesized and visualized using forest, strip, and dot plots, interpreted relative to American Academy of Pediatrics (AAP) recommendations. From 113 included studies, most reported sound levels substantially above recommended limits. Alarms, staff conversations, and incubator-associated equipment were consistently identified as major contributors. Respiratory support devices produced the highest internal noise levels, at times exceeding overall NICU ambient noise. Interventions such as staff training, behavioral adjustments, and environmental modifications yielded short-term improvements but rarely produced sustained reductions. NICU noise is a modifiable risk factor with significant developmental implications. Future strategies should integrate environmental design, technological innovation, and infant-focused interventions at the incubator-device interface to create safer, developmentally supportive acoustic conditions. Evidence also suggests that excessive shielding may reduce meaningful auditory input, raising concerns about potential auditory deprivation."

However, qualitative explorations are lacking, especially within culturally diverse settings. This study aims to explore the beliefs on the mechanisms of the relationship between diet, food systems, and mental health, and the lived experience of such, through a case study of one Caribbean Small Island Developing State, to inform culturally grounded public health strategies that integrate nutritional and psychological well-being. Fifteen interviews with food system stakeholders and five focus groups with the general public were conducted. Transcripts were analyzed using a grounded theory approach with a critical realist epistemological stance. Four major categories centered on beliefs of mechanistic effects of diet on mental health, as well as broader perspectives of the relationship between food systems, food experiences, and mental health. Participants believed that (1) unhealthy diets of processed and chemically treated foods contribute to poor mental health and that (2) food insecurity is a key threat to mental health, but they also believed that (3) consumption of locally produced foods and (4) residing in agricultural communities can be beneficial to mental health. Participants recognize that diet influences mental health through physiological, social, and structural pathways, but this connection is threatened by rising dependence on imported, processed foods. Along with complementary quantitative research, the findings highlight the potential of expanding nutritional health literacy and clinical guidance and strengthening local food systems and traditional diets for mental well-being among Caribbean Small Island Developing States."

Recent development and application of molecular autopsy have provided crucial support for addressing this problem. In such a context, this review systematically collates the potential molecular mechanisms underlying SUD with a focus on its genetic background. In addition, the progress and challenges of existing molecular autopsy strategies were elaborated in detail, in order to guide the multidisciplinary management of SUD from the perspective of forensic geneticists."

To evaluate school readiness at age 5 years and educational attainment at age 6 to 7 years in children born very preterm and to identify the early-life, neonatal, and socioeconomic factors associated with attainment. This retrospective cohort study included all infants born before gestational age (GA) 32 weeks in England who received care in a neonatal unit and survived to discharge. A linkage between the National Neonatal Research Database and the National Pupil Database was created to integrate neonatal clinical data with educational outcomes. The data analysis was performed between October 1, 2024, and October 31, 2025. Gestational age and area-level socioeconomic deprivation. The main outcome was school readiness at age 5 years (as measured by the Early Years Foundation Stage Profile [EYFSP]) and attainment in reading, writing, mathematics, and science at age 6 to 7 years. For each outcome, prevalence of not meeting the expected level of attainment across indices of socioeconomic deprivation and GA stratified by 23 to 26 weeks and 27 to 31 weeks were calculated. Of a total of 15\u202f857 children included (2595 born at GA 23-26 weeks [16.3%] and 13 262 born at GA 27-31 weeks [83.7%]; 8449 boys [53.3%]), 8602 (56.6%) did not meet the school readiness level at age 5 years, and 7789 (51.8%) did not meet expected attainment at age 6 to 7 years for writing, 7216 (48.1%) for math, 6354 (41.9%) for reading, and 5449 (36.0%) for science. Children born at GA 23 to 24 weeks had a higher odds of not meeting expected school readiness levels compared with those born at 31 weeks (adjusted odds ratio [AOR], 2.86 [95% CI, 2.19-3.73]). Children born in areas with the most deprivation had a higher risk of underattainment compared with those in areas with the least deprivation (EYFSP: AOR, 1.27 [95% CI, 1.11-1.45]). In adjusted models, male sex and season of birth were associated with increased risk (EYFSP: AOR, 1.96 [95% CI, 1.82-2.11] and 2.64 [95% CI, 2.41-2.90], respectively) alongside several potentially modifiable risk factors, including smoking during pregnancy (AOR range from 1.19 [95% CI, 1.08-1.31] for math to 1.31 [95% CI, 1.19-1.44] for reading); exposure to postnatal corticosteroids (EYFSP: AOR, 1.37 [95% CI, 1.13-1.65]); severe acquired neonatal brain injuries, particularly periventricular leukomalacia (EYFSP: AOR, 3.05 [95% CI, 2.04-4.58]) and hydrocephalus (EYFSP: AOR, 2.47 [95% CI, 1.48-4.13]); comorbidities of preterm birth, including necrotizing enterocolitis (EYFSP: AOR, 1.60 [95% CI, 1.20-2.14], retinopathy of prematurity (EYFSP: AOR, 1.46 [95% CI, 1.10-1.93], and bronchopulmonary dysplasia (EYFSP: AOR, 1.30 [95% CI, 1.18-1.44]); and nutrition during neonatal care (EYFSP: AOR, 1.19 [95% CI, 1.07-1.33] and 1.51 [95% CI, 1.37-1.66] for mixed feeding and exclusive formula feeding, respectively, vs breastfeeding). This cohort study of children born before GA 32 weeks found that preterm birth was associated with a substantial and persistent risk for educational underattainment across early school years, especially when combined with socioeconomic deprivation. Improving outcomes for children born preterm may require reducing social inequalities and minimizing comorbidities of preterm birth. Several modifiable early-life exposures offer practical targets for intervention, including maternal nonsmoking, appropriate corticosteroid use, and breastfeeding. Deferred school entry or targeted academic support may benefit children born very preterm, depending on birth season. These strategies may help parents, clinicians, educators, and policymakers improve long-term educational attainment for children born preterm."

Data concerning SUPC cases were obtained through a web-based registry managed by the Dutch Paediatric Surveillance Unit from April 2019 to April 2022. SUPC was defined as a collapse within 24 h of birth requiring resuscitation with at least positive pressure ventilation in infants born at \u226535 weeks of gestation and with a 5-min Apgar score \u22658. Of 94 registered SUPC cases, 60 met inclusion criteria: 52 cases occurred in hospital and 8 at home. The annual incidence ranged between 7 and 17 per 100,000 live births, with an average of 11 per 100,000. Median time to collapse was 64 min, with over two-thirds occurring within 2 h of birth. Collapses occurring at home occurred significantly later than those in hospital (165 min vs. 60 min; p < 0.05) and were associated with substantially higher mortality rates (37.5% vs. 6%; p < 0.05). Approximately half of all SUPC cases involved possible or definite airway obstruction, which - compared with other aetiologies - was more often related to preventable factors like reduced maternal vigilance and covering of the infant's nose and mouth. SUPC occurs in hospitals and at home, with later onset and higher mortality outside the hospital. Greater awareness and prevention are needed in both settings."

The neurobiological mechanisms involved remain unclear. We investigated the role of wake-promoting Orexin (Ox) and Histamine (HA) neurons in SIDS. Cerebrospinal fluid (CSF) Ox levels were measured in 61 living controls and 70 Sudden Unexpected Death Infants (SUDI: 38 SIDS, 32 explained deaths (ED)). HA and tele-methylhistamine (t-MeHA) were analyzed in an additional 46 SUDI (34 SIDS, 12 ED) and 42 controls. Immunohistochemistry was performed on hypothalamic tissue from 11 SIDS and 8 ED cases to quantify Ox and HA neuron numbers. CSF Ox levels did not differ overall between groups but were higher in SUDI infants aged 2-6 months. HA and t-MeHA levels were elevated in SUDI, likely reflecting postmortem release. Ox neuron numbers were increased in rostral hypothalamic region in SIDS compared with EDs, whereas HA neuron numbers were unchanged. SIDS is associated with increased Ox neuronal activity during the peak risk period, possibly reflecting a homeostatic upregulation in response to arousal deficit or repeated stress or hypoxia, while the role\u00a0of\u00a0HA system remains to be clarified with more sensitive biomarkers. First study evaluating orexin and histamine systems in SIDS using CSF and postmortem brain tissue. Identifies elevated orexin activity in SIDS infants, particularly in the 2-6 month risk window.

Despite advances in diagnostic techniques, many cases are still classified as unexplained and labeled as sudden infant death syndrome (SIDS). Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination. A narrative review of the literature (2000-2026) was conducted using PubMed and Scopus, focusing on under-recognized causes of SUDI and their diagnostic implications. Relevant studies were selected and organized into major pathological and forensic categories. Hidden causes of SUDI include a wide spectrum of conditions. Cardiac disorders-such as myocarditis, cardiomyopathies, and inherited arrhythmogenic syndromes-are frequently implicated and may require molecular autopsy for detection. Infectious diseases, often presenting with minimal or nonspecific findings, represent another important category, particularly viral and bacterial infections. Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses. Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control.

"abstract_text": "ID: 42003135\nTitle: A motor thalamic site in humans that suppresses involuntary breathing without awareness.\nAbstract: Breathing is generated by brainstem respiratory networks but can be controlled and modulated by forebrain activity. The recent clinical adoption of thalamic electrode implantation during intracranial electroencephalography (iEEG) provides a rare opportunity to examine the role of the human thalamus in respiratory control. Here, we tested whether thalamic stimulation alters breathing in 11 patients undergoing iEEG for epilepsy monitoring. Across 412 stimulation trials at 108 thalamic sites, thalamic stimulation induced central apnea in every participant. Apnea occurred in isolation without sensory or motor effects and without awareness of breathing cessation. Apnea occurred with stimulation of either the right or left thalamus and was observed across all ages, including participants as young as 22 mo. Volitional breathing and speech were preserved, indicating that respiratory motor pathways remained functional. In contrast, except for the amygdala, stimulation of other forebrain regions, including the hippocampus, insula, cingulate, and frontal, temporal, and parietal cortices, did not affect breathing. Respiratory inhibition depended on thalamic location, occurring most consistently with stimulation of the ventral lateral anterior (VLa) and ventral anterior (VA) nuclei. A machine learning algorithm localized the focal apneic region within the anterior motor thalamus, centered in VLa and extending into VA. Identification of a focal apneic site in the VLa/VA motor thalamus expands thalamic function, revealing a forebrain node capable of overriding brainstem respiratory control. This circuit may coordinate breathing with volitional behaviors such as speech, and dysfunction of this circuit may play a role in central apnea disorders, including sleep apnea, SUDEP, and SIDS.NEW & NOTEWORTHY This study identifies a focal site in the human motor thalamus where electrical stimulation suppresses involuntary, automatic breathing and induces apnea without awareness. Using intracranial recordings in pediatric and adult patients, we found that this effect localizes to the ventral anterior/ventral lateral anterior nuclei. These findings reveal a previously unrecognized thalamic function in the forebrain control of breathing."

Reelin, an extracellular matrix protein, is critical in neuronal migration and cell positioning. An altered reelin expression is hypothesized as a contributor to altered DG morphology. This study aimed to determine whether the number of reelin-expressing cells within the infant hippocampus is altered in (1) SIDS, and according to the presence of (2) SIDS risk factors (age, cigarette smoke exposure [CSE], sleep position, bed sharing, and upper respiratory tract infection [URTI]), and (3) DG morphology. Immunohistochemical staining of reelin was quantified (measured as the number of positive reelin cells/mm2) within the layers of the DG, CA4/Hilus, CA3-CA1, and subiculum in cases of explained SUDI (eSUDI, n\u2009=\u200912), SIDS I (n\u2009=\u20097), and SIDS II (n\u2009=\u200933). Reelin was highly correlated with age. After adjusting for age, SIDS II infants had a lower number of reelin immunopositive cells in the CA1, a finding that was more pronounced in bed sharers. Analysis of risk factors indicated lower reelin in the DG and CA3 of males, and in the DG of infants with URTI (when excluding bed sharers). The presence of the DG morphological feature of cluster ectopic cells was associated with a lower number of reelin cells across several hippocampal layers, whereas gaps were associated with higher numbers, with layers predominantly affected being the DG molecular layer and CA2 stratum radiatum."

In a retrospective cohort, patient records from 483\u2009284 infants born in Stockholm, Sweden, between 2002 and 2022 were screened for SUPC-related diagnoses. SUPC was defined as a collapse within the first 7\u2009days of life in near-term infants with good postnatal adaptation. Maternal, infant and event characteristics were collected. Urine was analysed for prostaglandin E2 (PGE2) metabolites in a subgroup of cases. We identified 149 cases of SUPC, corresponding to an incidence of 31 per 100\u2009000 live births, exceeding that of early onset sepsis caused by Group B Streptococcus. Half the SUPC cases occurred during the first four postnatal hours. The mortality was 7% and 26% suffered from neurological sequelae. The highest risk of SUPC coincided with the postnatal peak in PGE2 levels. All newborn infants were at risk of SUPC, especially within 24\u2009h of birth. SUPC was associated with early unsupervised skin-to-skin care and bed sharing. Guidelines promoting safe sleep and skin-to-skin care should be implemented to prevent SUPC and save the lives of newborn babies."

During the pandemic period, an increase in the incidence of Sudden Unexpected Infant Death (SUID) and Sudden Infant Death Syndrome (SIDS) was observed. Currently, their rates remain elevated compared to the prepandemic period. The pathogenetic mechanisms underlying the fulminant course of infection in infants leading to fatal outcomes remain insufficiently understood. In this study, we report for the first time the results of histological and immunohistochemical examination of the lungs in a case of COVID-19-associated SUID in a 2-month-old infant. The absence of similar studies in the available literature limits opportunities for analyzing the pathogenesis of SUID. Our data allow a detailed characterization of the histological changes in the lungs, the localization and range of SARS-CoV-2 nucleocapsid protein expression, the identification of molecular mechanisms underlying apoptosis in the pulmonary microvascular endothelium, and the elucidation of the role of endothelial dysfunction. Particular attention in this article is devoted to the role of cytokines (IL-6, TNF-\u03b1, and IFN-\u03b3) in the pathogenesis of hyperacute viral infection. The obtained data demonstrate substantial differences between the observed changes and the classic presentation of COVID-19 in older children. These findings offer prospects for improving prevention strategies and developing targeted therapy for fulminant forms of COVID-19, while also contributing to the understanding of SIDS pathogenesis."

It may be particularly important in global health research, where funding inequities and under-representation of local expertise in peer-reviewed research articles-often published by commercial publishers for substantial fees-can lead to evidence gaps in systematic reviews. However, searching, reporting and analysing grey literature poses conceptual and methodological challenges. We conducted a systematic scoping review of commercially published and grey literature examining food sources in Small Island Developing States (SIDS). The grey literature component aimed to expand understanding beyond built food environments and food retail and to promote epistemic justice by including traditionally excluded voices, knowledge and experiences. This might be especially important in SIDS, which, due to their small size, remote locations and limited global visibility, might not be well represented in commercially published literature. In this paper, we discuss how grey literature enriched our findings, offering detailed descriptions of diverse food sources, regional data and country comparisons less present in commercially published sources. These documents frequently reflected multisectoral initiatives and were developed through partnerships involving local stakeholders. Beyond highlighting the value of grey literature, we also provide practical guidance for its use in evidence synthesis. This includes key principles for effective searching and screening to support researchers aiming to incorporate grey literature in a systematic and transparent way. Our findings underline the importance of including grey literature to avoid excluding valuable perspectives and perpetuating structural imbalances in global health knowledge."

Reserve varies with developmental ontogeny, genotype, and acquired suppression (e.g., cytokine-mediated phenoconversion). Early infancy represents a developmental window in which clearance capacity and redox/energetic buffering may be comparatively constrained. We introduce a hypothesis-generating Three-Axis Convergence Framework (TCF) modeling interacting effects of (i) developmental/genetic reserve limits, (ii) immune-cytokine modulation of metabolism, and (iii) exposure/disposition context, and translate this synthesis into a structured postmortem interpretive tool integrated into the primary medicolegal autopsy, using an enhanced analytic panel applied selectively based on case context and specimen validity/QC to support mechanistic characterization of infant deaths remaining unexplained (often SUID/SIDS). A structured narrative synthesis was conducted spanning developmental pharmacology, pharmacogenetics, immunology, redox biology, neuropathology, and toxicology. Routine medicolegal postmortem practices used in SUID investigations were reviewed to identify measurement gaps that may limit mechanistic resolution in unexplained cases. The synthesis was formalized into five analytic domains: CYP450 capacity, immune/cytokine load, redox balance/energetics, neurochemical integrity, and xenobiotic/metal burden. The Metabolic Vulnerability Index (MVI) operationalizes the TCF as a five-domain ordinal scoring system (0-15). Domain 1 is anchored by hepatic CYP protein abundance (a more postmortem-stable proxy than CYP activity assays, which are generally constrained by rapid functional decay and QC limitations), normalized to adult reference and interpreted against age-matched developmental expectations. Domain-combination lookup tables route users to 14 mechanistically defined archetypes and specify modifier/exposure-context documentation. Appendices define an operational postmortem workflow, specimen validity rules, analytic QC constraints, detection limits, and a worked example. A Cytokine-Metabolic Suppression Profile (CMSP) is presented as an interpretive coherence summary and does not modify MVI scoring or certification. The MVI provides a structured framework for describing multidomain physiologic constraints in unexplained infant deaths alongside standard forensic practice. In this way, the TCF, MVI, and CMSP together offer a disciplined response to long-standing mechanistic uncertainty in early life-by enabling systematic measurement, coherent interpretation, and transparent identification of evidence gaps, rather than asserting new causes."

In neonatal intensive care units (NICUs), ambient noise frequently exceeds recommended thresholds and may interfere with auditory and neurodevelopmental maturation. During a critical period of sensory refinement, infants are exposed to unpredictable, high-intensity soundscapes generated by alarms, respiratory devices, and staff activity, contrasting sharply with the regulated acoustic environment of the womb. This systematic review aimed to identify, describe, and categorize noise sources in the NICU and to examine their potential impact on preterm infants. A systematic search across six major databases [MEDLINE, Embase, APA Psychinfo, CINHAL, Scopus, Web of Science (WOS); 2000-2026] identified studies reporting 24-h noise levels, day-night variation, and differences between incubator-internal and external sound. Eligible studies were synthesized and visualized using forest, strip, and dot plots, interpreted relative to American Academy of Pediatrics (AAP) recommendations. From 113 included studies, most reported sound levels substantially above recommended limits. Alarms, staff conversations, and incubator-associated equipment were consistently identified as major contributors. Respiratory support devices produced the highest internal noise levels, at times exceeding overall NICU ambient noise. Interventions such as staff training, behavioral adjustments, and environmental modifications yielded short-term improvements but rarely produced sustained reductions. NICU noise is a modifiable risk factor with significant developmental implications. Future strategies should integrate environmental design, technological innovation, and infant-focused interventions at the incubator-device interface to create safer, developmentally supportive acoustic conditions. Evidence also suggests that excessive shielding may reduce meaningful auditory input, raising concerns about potential auditory deprivation."

To evaluate school readiness at age 5 years and educational attainment at age 6 to 7 years in children born very preterm and to identify the early-life, neonatal, and socioeconomic factors associated with attainment. This retrospective cohort study included all infants born before gestational age (GA) 32 weeks in England who received care in a neonatal unit and survived to discharge. A linkage between the National Neonatal Research Database and the National Pupil Database was created to integrate neonatal clinical data with educational outcomes. The data analysis was performed between October 1, 2024, and October 31, 2025. Gestational age and area-level socioeconomic deprivation. The main outcome was school readiness at age 5 years (as measured by the Early Years Foundation Stage Profile [EYFSP]) and attainment in reading, writing, mathematics, and science at age 6 to 7 years. For each outcome, prevalence of not meeting the expected level of attainment across indices of socioeconomic deprivation and GA stratified by 23 to 26 weeks and 27 to 31 weeks were calculated. Of a total of 15\u202f857 children included (2595 born at GA 23-26 weeks [16.3%] and 13 262 born at GA 27-31 weeks [83.7%]; 8449 boys [53.3%]), 8602 (56.6%) did not meet the school readiness level at age 5 years, and 7789 (51.8%) did not meet expected attainment at age 6 to 7 years for writing, 7216 (48.1%) for math, 6354 (41.9%) for reading, and 5449 (36.0%) for science.

This cohort study of children born before GA 32 weeks found that preterm birth was associated with a substantial and persistent risk for educational underattainment across early school years, especially when combined with socioeconomic deprivation. Improving outcomes for children born preterm may require reducing social inequalities and minimizing comorbidities of preterm birth. Several modifiable early-life exposures offer practical targets for intervention, including maternal nonsmoking, appropriate corticosteroid use, and breastfeeding. Deferred school entry or targeted academic support may benefit children born very preterm, depending on birth season. These strategies may help parents, clinicians, educators, and policymakers improve long-term educational attainment for children born preterm."

This study aims to explore the beliefs on the mechanisms of the relationship between diet, food systems, and mental health, and the lived experience of such, through a case study of one Caribbean Small Island Developing State, to inform culturally grounded public health strategies that integrate nutritional and psychological well-being. Fifteen interviews with food system stakeholders and five focus groups with the general public were conducted. Transcripts were analyzed using a grounded theory approach with a critical realist epistemological stance. Four major categories centered on beliefs of mechanistic effects of diet on mental health, as well as broader perspectives of the relationship between food systems, food experiences, and mental health. Participants believed that (1) unhealthy diets of processed and chemically treated foods contribute to poor mental health and that (2) food insecurity is a key threat to mental health, but they also believed that (3) consumption of locally produced foods and (4) residing in agricultural communities can be beneficial to mental health. Participants recognize that diet influences mental health through physiological, social, and structural pathways, but this connection is threatened by rising dependence on imported, processed foods. Along with complementary quantitative research, the findings highlight the potential of expanding nutritional health literacy and clinical guidance and strengthening local food systems and traditional diets for mental well-being among Caribbean Small Island Developing States."

While many cases are labeled Sudden Infant Death Syndrome (SIDS) after extensive investigation, emerging evidence indicates that underlying, previously \"hidden\" pathological conditions\u2014ranging from metabolic disorders and cardiac channelopathies to subtle neuropathological and immune-metabolic constraints\u2014often contribute to these events. The integration of molecular autopsy and multidisciplinary diagnostic frameworks is essential to uncover these overlooked mechanisms.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe phenomenon of Sudden Unexpected Death in Infancy (SUDI) is defined by its unexpected nature and its complex diagnostic path, often involving \"Sudden Infant Death Syndrome (SIDS)\" as a diagnosis of exclusion. \"Sudden Unexpected Death in Infancy (SUDI) is the term given to all unexpected infant deaths, comprising accidental, non-accidental and natural deaths including Sudden Infant Death Syndrome (SIDS).\" Mechanistically, SIDS occurs during a vulnerable developmental window, where \"Sudden infant death syndrome (SIDS) occurs predominantly during sleep between 2 and 6 months of age, suggesting impaired maturation of arousal pathways.\" Research into the biological basis of these deaths reveals that \"Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination.\" These may involve genetic, infectious, or metabolic substrates. For instance, \"Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses.\" Furthermore, environmental and behavioral factors, including sleep position, co-sleeping, and soft bedding, can contribute to asphyxia. \"Approximately half of all SUPC cases involved possible or definite airway obstruction, which - compared with other aetiologies - was more often related to preventable factors like reduced maternal vigilance and covering of the infant's nose and mouth.\" Neuropathological assessment is critical as \"Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control.\" Given these complexities, a multidisciplinary approach incorporating molecular diagnostics and forensic neuropathology is necessary to transition from \"unexplained\" to identified, preventable causes.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The human motor thalamus contains a focal region (VLa/VA nuclei) capable of suppressing automatic breathing without awareness, a potential node in the pathogenesis of central apnea disorders like SIDS.\n* \"Hidden\" causes of death often include myocarditis and inherited arrhythmogenic syndromes, which are frequently missed without molecular autopsy.\n* Maternal type 1 diabetes is linked to delayed maturation of the breastmilk microbiome, an external determinant affecting early-life immune development.\n* Specific biomarkers, such as UCH-L1 in cord blood, are showing potential as early indicators of fetal cellular stress and neurodevelopmental risk.\n* Recent longitudinal research suggests that gut dysbiosis in neonates can persist into adulthood, potentially contributing to neurodevelopmental vulnerability.\n* The use of radiofrequency electrical conductivity in MRI imaging reveals a distinct biophysical dimension of perinatal brain development beyond water mobility.\n* Post-mortem fundus photographs exhibit specific patterns, such as macular folds, which are associated with longer post-mortem intervals rather than necessarily indicating trauma.\n* Noise pollution in the NICU is a major modifiable factor; alarms and staff activity create an acoustic environment often substantially above recommended guidelines.\n* The \"Metabolic Vulnerability Index\" is a new, structured framework allowing for the assessment of five-domain physiologic constraints in infant deaths.\n* Socioeconomic deprivation, as indexed by the Area Deprivation Index, is significantly associated with altered white matter myelination trajectories in children from infancy through childhood.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The neurobiological mechanisms involved remain unclear. We investigated the role of wake-promoting Orexin (Ox) and Histamine (HA) neurons in SIDS. Cerebrospinal fluid (CSF) Ox levels were measured in 61 living controls and 70 Sudden Unexpected Death Infants (SUDI: 38 SIDS, 32 explained deaths (ED)). HA and tele-methylhistamine (t-MeHA) were analyzed in an additional 46 SUDI (34 SIDS, 12 ED) and 42 controls. Immunohistochemistry was performed on hypothalamic tissue from 11 SIDS and 8 ED cases to quantify Ox and HA neuron numbers. CSF Ox levels did not differ overall between groups but were higher in SUDI infants aged 2-6 months. HA and t-MeHA levels were elevated in SUDI, likely reflecting postmortem release. Ox neuron numbers were increased in rostral hypothalamic region in SIDS compared with EDs, whereas HA neuron numbers were unchanged. SIDS is associated with increased Ox neuronal activity during the peak risk period, possibly reflecting a homeostatic upregulation in response to arousal deficit or repeated stress or hypoxia, while the role\u00a0of\u00a0HA system remains to be clarified with more sensitive biomarkers. First study evaluating orexin and histamine systems in SIDS using CSF and postmortem brain tissue. Identifies elevated orexin activity in SIDS infants, particularly in the 2-6 month risk window. No evidence to date for direct histamine involvement; need for more sensitive biomarkers. Suggests orexin system as a potential biomarker for SIDS risk stratification. Highlights the importance of combined neurobiological approaches for prevention."

As in other developed countries, Australian SUDI rates are relatively low, but incidence rates have remained essentially unchanged since 2004. To increase our understanding of these deaths, we reviewed a cohort of SUDI cases with positive hair toxicology, focussing on toxicology results, pathology findings, and SIDS risk factors.\u00a0All infant deaths between 1st January 2014 and 31st of December 2023 with positive hair toxicology in the state of Victoria, Australia, were reviewed for toxicology results, pathology findings and SIDS risk factors.\u00a0A total of 99 infant deaths met the selection criteria. At least one SIDS risk factor was reported in every case, with a median of 5 per case, highlighting that these infants likely had a high cumulative risk for SIDS.

"abstract_text": "ID: 42003135\nTitle: A motor thalamic site in humans that suppresses involuntary breathing without awareness.\nAbstract: Breathing is generated by brainstem respiratory networks but can be controlled and modulated by forebrain activity. The recent clinical adoption of thalamic electrode implantation during intracranial electroencephalography (iEEG) provides a rare opportunity to examine the role of the human thalamus in respiratory control. Here, we tested whether thalamic stimulation alters breathing in 11 patients undergoing iEEG for epilepsy monitoring. Across 412 stimulation trials at 108 thalamic sites, thalamic stimulation induced central apnea in every participant. Apnea occurred in isolation without sensory or motor effects and without awareness of breathing cessation. Apnea occurred with stimulation of either the right or left thalamus and was observed across all ages, including participants as young as 22 mo. Volitional breathing and speech were preserved, indicating that respiratory motor pathways remained functional. In contrast, except for the amygdala, stimulation of other forebrain regions, including the hippocampus, insula, cingulate, and frontal, temporal, and parietal cortices, did not affect breathing. Respiratory inhibition depended on thalamic location, occurring most consistently with stimulation of the ventral lateral anterior (VLa) and ventral anterior (VA) nuclei. A machine learning algorithm localized the focal apneic region within the anterior motor thalamus, centered in VLa and extending into VA. Identification of a focal apneic site in the VLa/VA motor thalamus expands thalamic function, revealing a forebrain node capable of overriding brainstem respiratory control. This circuit may coordinate breathing with volitional behaviors such as speech, and dysfunction of this circuit may play a role in central apnea disorders, including sleep apnea, SUDEP, and SIDS.NEW & NOTEWORTHY This study identifies a focal site in the human motor thalamus where electrical stimulation suppresses involuntary, automatic breathing and induces apnea without awareness. Using intracranial recordings in pediatric and adult patients, we found that this effect localizes to the ventral anterior/ventral lateral anterior nuclei. These findings reveal a previously unrecognized thalamic function in the forebrain control of breathing."

Reelin, an extracellular matrix protein, is critical in neuronal migration and cell positioning. An altered reelin expression is hypothesized as a contributor to altered DG morphology. This study aimed to determine whether the number of reelin-expressing cells within the infant hippocampus is altered in (1) SIDS, and according to the presence of (2) SIDS risk factors (age, cigarette smoke exposure [CSE], sleep position, bed sharing, and upper respiratory tract infection [URTI]), and (3) DG morphology. Immunohistochemical staining of reelin was quantified (measured as the number of positive reelin cells/mm2) within the layers of the DG, CA4/Hilus, CA3-CA1, and subiculum in cases of explained SUDI (eSUDI, n\u2009=\u200912), SIDS I (n\u2009=\u20097), and SIDS II (n\u2009=\u200933). Reelin was highly correlated with age. After adjusting for age, SIDS II infants had a lower number of reelin immunopositive cells in the CA1, a finding that was more pronounced in bed sharers. Analysis of risk factors indicated lower reelin in the DG and CA3 of males, and in the DG of infants with URTI (when excluding bed sharers). The presence of the DG morphological feature of cluster ectopic cells was associated with a lower number of reelin cells across several hippocampal layers, whereas gaps were associated with higher numbers, with layers predominantly affected being the DG molecular layer and CA2 stratum radiatum."

We identified 149 cases of SUPC, corresponding to an incidence of 31 per 100\u2009000 live births, exceeding that of early onset sepsis caused by Group B Streptococcus. Half the SUPC cases occurred during the first four postnatal hours. The mortality was 7% and 26% suffered from neurological sequelae. The highest risk of SUPC coincided with the postnatal peak in PGE2 levels. All newborn infants were at risk of SUPC, especially within 24\u2009h of birth. SUPC was associated with early unsupervised skin-to-skin care and bed sharing. Guidelines promoting safe sleep and skin-to-skin care should be implemented to prevent SUPC and save the lives of newborn babies."

It may be particularly important in global health research, where funding inequities and under-representation of local expertise in peer-reviewed research articles-often published by commercial publishers for substantial fees-can lead to evidence gaps in systematic reviews. However, searching, reporting and analysing grey literature poses conceptual and methodological challenges. We conducted a systematic scoping review of commercially published and grey literature examining food sources in Small Island Developing States (SIDS). The grey literature component aimed to expand understanding beyond built food environments and food retail and to promote epistemic justice by including traditionally excluded voices, knowledge and experiences. This might be especially important in SIDS, which, due to their small size, remote locations and limited global visibility, might not be well represented in commercially published literature. In this paper, we discuss how grey literature enriched our findings, offering detailed descriptions of diverse food sources, regional data and country comparisons less present in commercially published sources. These documents frequently reflected multisectoral initiatives and were developed through partnerships involving local stakeholders. Beyond highlighting the value of grey literature, we also provide practical guidance for its use in evidence synthesis. This includes key principles for effective searching and screening to support researchers aiming to incorporate grey literature in a systematic and transparent way. Our findings underline the importance of including grey literature to avoid excluding valuable perspectives and perpetuating structural imbalances in global health knowledge."

Reserve varies with developmental ontogeny, genotype, and acquired suppression (e.g., cytokine-mediated phenoconversion). Early infancy represents a developmental window in which clearance capacity and redox/energetic buffering may be comparatively constrained. We introduce a hypothesis-generating Three-Axis Convergence Framework (TCF) modeling interacting effects of (i) developmental/genetic reserve limits, (ii) immune-cytokine modulation of metabolism, and (iii) exposure/disposition context, and translate this synthesis into a structured postmortem interpretive tool integrated into the primary medicolegal autopsy, using an enhanced analytic panel applied selectively based on case context and specimen validity/QC to support mechanistic characterization of infant deaths remaining unexplained (often SUID/SIDS). A structured narrative synthesis was conducted spanning developmental pharmacology, pharmacogenetics, immunology, redox biology, neuropathology, and toxicology. Routine medicolegal postmortem practices used in SUID investigations were reviewed to identify measurement gaps that may limit mechanistic resolution in unexplained cases. The synthesis was formalized into five analytic domains: CYP450 capacity, immune/cytokine load, redox balance/energetics, neurochemical integrity, and xenobiotic/metal burden. The Metabolic Vulnerability Index (MVI) operationalizes the TCF as a five-domain ordinal scoring system (0-15). Domain 1 is anchored by hepatic CYP protein abundance (a more postmortem-stable proxy than CYP activity assays, which are generally constrained by rapid functional decay and QC limitations), normalized to adult reference and interpreted against age-matched developmental expectations. Domain-combination lookup tables route users to 14 mechanistically defined archetypes and specify modifier/exposure-context documentation. Appendices define an operational postmortem workflow, specimen validity rules, analytic QC constraints, detection limits, and a worked example. A Cytokine-Metabolic Suppression Profile (CMSP) is presented as an interpretive coherence summary and does not modify MVI scoring or certification. The MVI provides a structured framework for describing multidomain physiologic constraints in unexplained infant deaths alongside standard forensic practice. In this way, the TCF, MVI, and CMSP together offer a disciplined response to long-standing mechanistic uncertainty in early life-by enabling systematic measurement, coherent interpretation, and transparent identification of evidence gaps, rather than asserting new causes."

In neonatal intensive care units (NICUs), ambient noise frequently exceeds recommended thresholds and may interfere with auditory and neurodevelopmental maturation. During a critical period of sensory refinement, infants are exposed to unpredictable, high-intensity soundscapes generated by alarms, respiratory devices, and staff activity, contrasting sharply with the regulated acoustic environment of the womb. This systematic review aimed to identify, describe, and categorize noise sources in the NICU and to examine their potential impact on preterm infants. A systematic search across six major databases [MEDLINE, Embase, APA Psychinfo, CINHAL, Scopus, Web of Science (WOS); 2000-2026] identified studies reporting 24-h noise levels, day-night variation, and differences between incubator-internal and external sound. Eligible studies were synthesized and visualized using forest, strip, and dot plots, interpreted relative to American Academy of Pediatrics (AAP) recommendations. From 113 included studies, most reported sound levels substantially above recommended limits. Alarms, staff conversations, and incubator-associated equipment were consistently identified as major contributors. Respiratory support devices produced the highest internal noise levels, at times exceeding overall NICU ambient noise. Interventions such as staff training, behavioral adjustments, and environmental modifications yielded short-term improvements but rarely produced sustained reductions. NICU noise is a modifiable risk factor with significant developmental implications. Future strategies should integrate environmental design, technological innovation, and infant-focused interventions at the incubator-device interface to create safer, developmentally supportive acoustic conditions. Evidence also suggests that excessive shielding may reduce meaningful auditory input, raising concerns about potential auditory deprivation."

Comprehensive understanding of the cause of death in SUD cases could not only provide scientific guidance for judicial investigations, but also help to prevent such tragedies from recurring by identifying at-risk individuals. Recent development and application of molecular autopsy have provided crucial support for addressing this problem. In such a context, this review systematically collates the potential molecular mechanisms underlying SUD with a focus on its genetic background. In addition, the progress and challenges of existing molecular autopsy strategies were elaborated in detail, in order to guide the multidisciplinary management of SUD from the perspective of forensic geneticists."

To evaluate school readiness at age 5 years and educational attainment at age 6 to 7 years in children born very preterm and to identify the early-life, neonatal, and socioeconomic factors associated with attainment. This retrospective cohort study included all infants born before gestational age (GA) 32 weeks in England who received care in a neonatal unit and survived to discharge. A linkage between the National Neonatal Research Database and the National Pupil Database was created to integrate neonatal clinical data with educational outcomes. The data analysis was performed between October 1, 2024, and October 31, 2025. Gestational age and area-level socioeconomic deprivation. The main outcome was school readiness at age 5 years (as measured by the Early Years Foundation Stage Profile [EYFSP]) and attainment in reading, writing, mathematics, and science at age 6 to 7 years. For each outcome, prevalence of not meeting the expected level of attainment across indices of socioeconomic deprivation and GA stratified by 23 to 26 weeks and 27 to 31 weeks were calculated. Of a total of 15\u202f857 children included (2595 born at GA 23-26 weeks [16.3%] and 13 262 born at GA 27-31 weeks [83.7%]; 8449 boys [53.3%]), 8602 (56.6%) did not meet the school readiness level at age 5 years, and 7789 (51.8%) did not meet expected attainment at age 6 to 7 years for writing, 7216 (48.1%) for math, 6354 (41.9%) for reading, and 5449 (36.0%) for science. Children born at GA 23 to 24 weeks had a higher odds of not meeting expected school readiness levels compared with those born at 31 weeks (adjusted odds ratio [AOR], 2.86 [95% CI, 2.19-3.73]). Children born in areas with the most deprivation had a higher risk of underattainment compared with those in areas with the least deprivation (EYFSP: AOR, 1.27 [95% CI, 1.11-1.45]). In adjusted models, male sex and season of birth were associated with increased risk (EYFSP: AOR, 1.96 [95% CI, 1.82-2.11] and 2.64 [95% CI, 2.41-2.90], respectively) alongside several potentially modifiable risk factors, including smoking during pregnancy (AOR range from 1.19 [95% CI, 1.08-1.31] for math to 1.31 [95% CI, 1.19-1.44] for reading); exposure to postnatal corticosteroids (EYFSP: AOR, 1.37 [95% CI, 1.13-1.65]); severe acquired neonatal brain injuries, particularly periventricular leukomalacia (EYFSP: AOR, 3.05 [95% CI, 2.04-4.58]) and hydrocephalus (EYFSP: AOR, 2.47 [95% CI, 1.48-4.13]); comorbidities of preterm birth, including necrotizing enterocolitis (EYFSP: AOR, 1.60 [95% CI, 1.20-2.14], retinopathy of prematurity (EYFSP: AOR, 1.46 [95% CI, 1.10-1.93], and bronchopulmonary dysplasia (EYFSP: AOR, 1.30 [95% CI, 1.18-1.44]); and nutrition during neonatal care (EYFSP: AOR, 1.19 [95% CI, 1.07-1.33] and 1.51 [95% CI, 1.37-1.66] for mixed feeding and exclusive formula feeding, respectively, vs breastfeeding). This cohort study of children born before GA 32 weeks found that preterm birth was associated with a substantial and persistent risk for educational underattainment across early school years, especially when combined with socioeconomic deprivation. Improving outcomes for children born preterm may require reducing social inequalities and minimizing comorbidities of preterm birth. Several modifiable early-life exposures offer practical targets for intervention, including maternal nonsmoking, appropriate corticosteroid use, and breastfeeding. Deferred school entry or targeted academic support may benefit children born very preterm, depending on birth season. These strategies may help parents, clinicians, educators, and policymakers improve long-term educational attainment for children born preterm."

This study investigated the incidence, aetiology, and circumstances of SUPC in the Netherlands and assessed differences between in-hospital and home settings. Data concerning SUPC cases were obtained through a web-based registry managed by the Dutch Paediatric Surveillance Unit from April 2019 to April 2022. SUPC was defined as a collapse within 24 h of birth requiring resuscitation with at least positive pressure ventilation in infants born at \u226535 weeks of gestation and with a 5-min Apgar score \u22658. Of 94 registered SUPC cases, 60 met inclusion criteria: 52 cases occurred in hospital and 8 at home. The annual incidence ranged between 7 and 17 per 100,000 live births, with an average of 11 per 100,000. Median time to collapse was 64 min, with over two-thirds occurring within 2 h of birth. Collapses occurring at home occurred significantly later than those in hospital (165 min vs. 60 min; p < 0.05) and were associated with substantially higher mortality rates (37.5% vs. 6%; p < 0.05). Approximately half of all SUPC cases involved possible or definite airway obstruction, which - compared with other aetiologies - was more often related to preventable factors like reduced maternal vigilance and covering of the infant's nose and mouth. SUPC occurs in hospitals and at home, with later onset and higher mortality outside the hospital. Greater awareness and prevention are needed in both settings."

However, qualitative explorations are lacking, especially within culturally diverse settings. This study aims to explore the beliefs on the mechanisms of the relationship between diet, food systems, and mental health, and the lived experience of such, through a case study of one Caribbean Small Island Developing State, to inform culturally grounded public health strategies that integrate nutritional and psychological well-being. Fifteen interviews with food system stakeholders and five focus groups with the general public were conducted. Transcripts were analyzed using a grounded theory approach with a critical realist epistemological stance. Four major categories centered on beliefs of mechanistic effects of diet on mental health, as well as broader perspectives of the relationship between food systems, food experiences, and mental health. Participants believed that (1) unhealthy diets of processed and chemically treated foods contribute to poor mental health and that (2) food insecurity is a key threat to mental health, but they also believed that (3) consumption of locally produced foods and (4) residing in agricultural communities can be beneficial to mental health. Participants recognize that diet influences mental health through physiological, social, and structural pathways, but this connection is threatened by rising dependence on imported, processed foods. Along with complementary quantitative research, the findings highlight the potential of expanding nutritional health literacy and clinical guidance and strengthening local food systems and traditional diets for mental well-being among Caribbean Small Island Developing States."

While many cases are labeled Sudden Infant Death Syndrome (SIDS) after extensive investigation, emerging evidence indicates that underlying, previously \"hidden\" pathological conditions\u2014ranging from metabolic disorders and cardiac channelopathies to subtle neuropathological and immune-metabolic constraints\u2014often contribute to these events. The integration of molecular autopsy and multidisciplinary diagnostic frameworks is essential to uncover these overlooked mechanisms.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe phenomenon of Sudden Unexpected Death in Infancy (SUDI) is defined by its unexpected nature and its complex diagnostic path, often involving \"Sudden Infant Death Syndrome (SIDS)\" as a diagnosis of exclusion. \"Sudden Unexpected Death in Infancy (SUDI) is the term given to all unexpected infant deaths, comprising accidental, non-accidental and natural deaths including Sudden Infant Death Syndrome (SIDS).\" Mechanistically, SIDS occurs during a vulnerable developmental window, where \"Sudden infant death syndrome (SIDS) occurs predominantly during sleep between 2 and 6 months of age, suggesting impaired maturation of arousal pathways.\" Research into the biological basis of these deaths reveals that \"Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination.\" These may involve genetic, infectious, or metabolic substrates. For instance, \"Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses.\" Furthermore, environmental and behavioral factors, including sleep position, co-sleeping, and soft bedding, can contribute to asphyxia. \"Approximately half of all SUPC cases involved possible or definite airway obstruction, which - compared with other aetiologies - was more often related to preventable factors like reduced maternal vigilance and covering of the infant's nose and mouth.\" Neuropathological assessment is critical as \"Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control.\" Given these complexities, a multidisciplinary approach incorporating molecular diagnostics and forensic neuropathology is necessary to transition from \"unexplained\" to identified, preventable causes.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The human motor thalamus contains a focal region (VLa/VA nuclei) capable of suppressing automatic breathing without awareness, a potential node in the pathogenesis of central apnea disorders like SIDS.\n* \"Hidden\" causes of death often include myocarditis and inherited arrhythmogenic syndromes, which are frequently missed without molecular autopsy.\n* Maternal type 1 diabetes is linked to delayed maturation of the breastmilk microbiome, an external determinant affecting early-life immune development.\n* Specific biomarkers, such as UCH-L1 in cord blood, are showing potential as early indicators of fetal cellular stress and neurodevelopmental risk.\n* Recent longitudinal research suggests that gut dysbiosis in neonates can persist into adulthood, potentially contributing to neurodevelopmental vulnerability.\n* The use of radiofrequency electrical conductivity in MRI imaging reveals a distinct biophysical dimension of perinatal brain development beyond water mobility.\n* Post-mortem fundus photographs exhibit specific patterns, such as macular folds, which are associated with longer post-mortem intervals rather than necessarily indicating trauma.\n* Noise pollution in the NICU is a major modifiable factor; alarms and staff activity create an acoustic environment often substantially above recommended guidelines.\n* The \"Metabolic Vulnerability Index\" is a new, structured framework allowing for the assessment of five-domain physiologic constraints in infant deaths.\n* Socioeconomic deprivation, as indexed by the Area Deprivation Index, is significantly associated with altered white matter myelination trajectories in children from infancy through childhood.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In this context, invasive or introduced woody species may contribute substantially to biomass accumulation in degraded drylands, although quantitative evidence for Neltuma juliflora remains limited. This study provides the first block-scale assessment of carbon stocks in N. juliflora stands on Santiago Island, Cabo Verde, using validated allometric equations and topsoil analyses across 11 sampling blocks. A total of 463 individuals were measured. Aboveground carbon stocks varied markedly among blocks, ranging from 27.4 to 85.3 Mg C ha\u207b1, and were strongly associated with variation in stand structure, particularly equivalent diameter, tree height and stand density. In contrast, soil organic carbon in the 0-20 cm layer remained comparatively low, averaging 7.1 Mg C ha\u207b1, and showed no significant radial trend with increasing distance from the tree. Instead, variation in soil carbon was more closely associated with block-level edaphic heterogeneity than with local canopy effects. Belowground carbon, estimated using a fixed root-to-shoot ratio, followed the same spatial pattern as aboveground biomass and should therefore be interpreted as a derived rather than independently measured pool. Overall, the results demonstrate that N. juliflora can support substantial woody carbon storage under semi-arid insular conditions, whereas shallow soil carbon remains limited. These findings provide an important baseline for dryland carbon assessment in Cabo Verde and support a cautious, site-specific evaluation of the species in restoration and climate-mitigation strategies given its recognised invasive potential.\n\nID: 42441360\nTitle: A Qualitative Evaluation of Infant Safe Sleep Following Free Crib Provision.\nAbstract: Unsafe sleep practices are a leading cause of infant mortality in the United States. Authors of this qualitative study examined parental perceptions and reported practices related to infant safe sleep among families who received a free portable crib after their infant's birth. Specifically, authors explored whether families used the portable crib to provide a safe sleep environment for their infants. Parents of infants aged 2 to 11 months who received a free portable crib were invited to participate in a structured 11-question interview assessing safe sleep perceptions and practices, including crib use. Eleven families participated in the study. Six themes emerged from the interviews: (1) parents recalled receiving safe sleep counseling, often in considerable detail; (2) many parents initially planned to bed-share before receiving the crib; (3) reported sleep practices frequently differed from established safe sleep recommendations; (4) parents described multiple reasons for not consistently following recommendations; (5) participants supported the continued provision of free cribs and safe sleep counseling; and (6) parents generally found the crib helpful, although it often was used alongside other sleep arrangements. Although parents recalled receiving safe sleep counseling, reported sleep practices frequently did not align with recommended guidelines. Further research is needed to better understand this gap and to identify strategies that improve adherence to safe sleep recommendations.\n\nID: 42433390\nTitle: Assessing the state of deep-sea biological knowledge and charting a path for scientific research in Barbados.\nAbstract: For Small Island Developing States, including those in the Caribbean, the deep sea remains a challenging ecosystem to study as it requires expensive technology and specialised expertise. The deep-sea environment of Barbados (200-5,776 m) accounts for 99.8% of its Exclusive Economic Zone (EEZ). Barbados is presently in the initial phases of developing a marine spatial plan for its EEZ. Comprehensive baseline information on the deep-sea ecosystems is crucial for evidence-based decision-making. This research assesses the state of deep-sea biological knowledge in Barbados via a comprehensive review of species records from peer-reviewed and grey literature, as well as museum and biodiversity databases. We found 1,589 biological records constituting 309 families and 624 species and morphospecies for Barbados' deep sea. Strikingly, richness analyses estimate that just 20% of the species and 48% of the families inhabiting Barbados' deep sea have been recorded. We also discuss limitations in existing knowledge, including vast geographic areas and depths still requiring research, as well as the varied methods of deep-sea observation and sampling utilised thus far, and the associated influence on the taxonomic composition of the known deep-sea community. Although limited, this assessment of deep-sea biodiversity information has provided insights to assist with the creation of a road map which decision-makers can utilize to guide future management and research activities.\n\nID: 42349911\nTitle: The value of adding 'grey literature' in evidence synthesis for equity-driven global health: a case study from Small Island Developing States.\nAbstract: Grey literature, defined as evidence 'not controlled by commercial publishers', can enhance the comprehensiveness, timeliness and balance of evidence reviews. It may be particularly important in global health research, where funding inequities and under-representation of local expertise in peer-reviewed research articles-often published by commercial publishers for substantial fees-can lead to evidence gaps in systematic reviews. However, searching, reporting and analysing grey literature poses conceptual and methodological challenges. We conducted a systematic scoping review of commercially published and grey literature examining food sources in Small Island Developing States (SIDS). The grey literature component aimed to expand understanding beyond built food environments and food retail and to promote epistemic justice by including traditionally excluded voices, knowledge and experiences. This might be especially important in SIDS, which, due to their small size, remote locations and limited global visibility, might not be well represented in commercially published literature. In this paper, we discuss how grey literature enriched our findings, offering detailed descriptions of diverse food sources, regional data and country comparisons less present in commercially published sources. These documents frequently reflected multisectoral initiatives and were developed through partnerships involving local stakeholders. Beyond highlighting the value of grey literature, we also provide practical guidance for its use in evidence synthesis. This includes key principles for effective searching and screening to support researchers aiming to incorporate grey literature in a systematic and transparent way. Our findings underline the importance of including grey literature to avoid excluding valuable perspectives and perpetuating structural imbalances in global health knowledge.\n\nID: 42332249\nTitle: A quest for a histaminergic or orexinergic biomarker for sudden infant death syndrome.\nAbstract: Sudden infant death syndrome (SIDS) occurs predominantly during sleep between 2 and 6 months of age, suggesting impaired maturation of arousal pathways. The neurobiological mechanisms involved remain unclear. We investigated the role of wake-promoting Orexin (Ox) and Histamine (HA) neurons in SIDS. Cerebrospinal fluid (CSF) Ox levels were measured in 61 living controls and 70 Sudden Unexpected Death Infants (SUDI: 38 SIDS, 32 explained deaths (ED)). HA and tele-methylhistamine (t-MeHA) were analyzed in an additional 46 SUDI (34 SIDS, 12 ED) and 42 controls. Immunohistochemistry was performed on hypothalamic tissue from 11 SIDS and 8 ED cases to quantify Ox and HA neuron numbers. CSF Ox levels did not differ overall between groups but were higher in SUDI infants aged 2-6 months. HA and t-MeHA levels were elevated in SUDI, likely reflecting postmortem release. Ox neuron numbers were increased in rostral hypothalamic region in SIDS compared with EDs, whereas HA neuron numbers were unchanged. SIDS is associated with increased Ox neuronal activity during the peak risk period, possibly reflecting a homeostatic upregulation in response to arousal deficit or repeated stress or hypoxia, while the role\u00a0of\u00a0HA system remains to be clarified with more sensitive biomarkers. First study evaluating orexin and histamine systems in SIDS using CSF and postmortem brain tissue. Identifies elevated orexin activity in SIDS infants, particularly in the 2-6 month risk window. No evidence to date for direct histamine involvement; need for more sensitive biomarkers. Suggests orexin system as a potential biomarker for SIDS risk stratification. Highlights the importance of combined neurobiological approaches for prevention.\n\nID: 42279599\nTitle: Hidden and Under-Recognized Causes of Sudden Unexpected Death in Infancy (SUDI): A Comprehensive Review of Autopsy Findings.\nAbstract: Sudden unexpected death in infancy (SUDI) remains a major challenge in pediatric pathology and forensic medicine. Despite advances in diagnostic techniques, many cases are still classified as unexplained and labeled as sudden infant death syndrome (SIDS). Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination. A narrative review of the literature (2000-2026) was conducted using PubMed and Scopus, focusing on under-recognized causes of SUDI and their diagnostic implications. Relevant studies were selected and organized into major pathological and forensic categories. Hidden causes of SUDI include a wide spectrum of conditions. Cardiac disorders-such as myocarditis, cardiomyopathies, and inherited arrhythmogenic syndromes-are frequently implicated and may require molecular autopsy for detection. Infectious diseases, often presenting with minimal or nonspecific findings, represent another important category, particularly viral and bacterial infections. Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses. Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control. Environmental, toxicological, and medico-legal factors-including unsafe sleep conditions, toxic exposures, and inflicted injury-must also be considered. SUDI is a multifactorial entity in which many unexplained deaths may be attributable to identifiable but overlooked conditions. A standardized, multidisciplinary approach integrating autopsy, ancillary investigations, and molecular diagnostics is essential to improve diagnostic accuracy and support prevention strategies.\n\nID: 42243680\nTitle: Trait-based analysis of yield formation and nitrogen use efficiency in wheat genotypes under integrated organic and NPK fertilization in low-fertility sandy soil.\nAbstract: Wheat productivity in irrigated arid and semi-arid regions is constrained by low soil fertility and inefficient use of mineral fertilizers. A process-level understanding of how integrated organic and mineral fertilization interacts with genotype to control yield formation, grain nitrogen (N) partitioning, and nitrogen use efficiency (NUE) in coarse-textured soils remains limited. Here, we quantified the combined effects of NPK fertilization regime (100% soil application vs. increasing proportions of fertigation), compost rates, and wheat (Triticum aestivum L.) genotype on yield, yield components, grain quality, and NUE in a low-fertility sandy soil over two growing seasons in an arid environment. We hypothesized that increasing fertigation would additively enhance yield components and NUE with compost, with diminishing returns at high compost rates, and that genotypes would differ in the relationship between grain yield and grain protein concentration. A split-split plot design included three cultivars (Sakha-95, Sids-14, Misr-1), four NPK regimes (F1: 100% soil; F2-F4: 50-100% fertigation), and three compost rates (12, 24, and 36 t ha\u207b\u00b9). Full fertigation (F4) increased grain yield and NUE by 49.8% relative to 100% soil application, primarily by increasing spike density, grains spike\u207b\u00b9 and 1000-grain weight. Compost further enhanced yield and NUE, with 36 t ha\u207b\u00b9 giving 18% higher grain yield than 12 t ha\u207b\u00b9. Genotypes differed markedly: Sakha-95 achieved the highest grain and biological yields and NUE, whereas Sids-14 and Misr-1 produced higher grain protein. Path analysis showed that spikes m\u207b\u00b2, 1000-grain weight, and fertile spikelets spike\u207b\u00b9 had the largest direct effects on grain yield, while principal component analysis revealed that combinations of high fertigation and high compost clustered with superior trait profiles. Intensive fertigation led to diminishing returns from compost at high rates, indicating an optimum organic input under high soluble nutrient supply. Together, these results provide trait-based insights into how integrated organic-mineral fertilization and genotype control yield formation and N recovery in sandy, low-fertility soils. The findings are relevant to irrigated field-crop systems on light-textured soils across arid and semi-arid regions where fertigation and organic amendments are increasingly used to improve NUE and sustainability.\n\nID: 42170192\nTitle: Forensic neuropathology: 2026 update.\nAbstract: This review discusses key publications in forensic neuropathology from the 2025 literature. In abusive head trauma (AHT), biomechanical models help clarify injury mechanisms, particularly the role of sagittal angular acceleration in younger infants. However, challenges remain, such as detecting subtle brainstem pathology with neuroimaging, stressing the need for prospective clinicopathological correlation. Meanwhile, understanding of chronic traumatic encephalopathy (CTE) is expanding beyond contact sports to include victims of intimate partner violence. Research on sudden unexpected death in epilepsy (SUDEP) indicates overlaps with sudden infant death syndrome (SIDS) and identifies key risk factors. At the same time, forensic neuropathology's primary role remains the exclusion of other causes of death. Artificial intelligence shows promise for analyzing radiological and histopathological data in traumatic brain injury (TBI) and epilepsy, though its adoption for routine purposes remains a distant goal. Further developments include a better understanding of the cerebellum's vulnerability to TBI, standardized postmortem MRI protocols, and the use of cerebrospinal fluid biomarkers, such as GFAP and S100B, to estimate time of death. Finally, research continues to probe the complex links between brain morphology and behavior, and recent studies of the neuropathology of alcohol use disorder have revealed microglial changes rather than overt neuronal loss.\n\nID: 42124028\nTitle: Understanding the Connection Between Diet, Food Systems and Mental Health: A Qualitative Exploration of a Caribbean Small Island Developing State.\nAbstract: Diet is implicated in the high burden of mental health on society, and research examining associations between these two fields is growing. However, qualitative explorations are lacking, especially within culturally diverse settings. This study aims to explore the beliefs on the mechanisms of the relationship between diet, food systems, and mental health, and the lived experience of such, through a case study of one Caribbean Small Island Developing State, to inform culturally grounded public health strategies that integrate nutritional and psychological well-being. Fifteen interviews with food system stakeholders and five focus groups with the general public were conducted. Transcripts were analyzed using a grounded theory approach with a critical realist epistemological stance. Four major categories centered on beliefs of mechanistic effects of diet on mental health, as well as broader perspectives of the relationship between food systems, food experiences, and mental health. Participants believed that (1) unhealthy diets of processed and chemically treated foods contribute to poor mental health and that (2) food insecurity is a key threat to mental health, but they also believed that (3) consumption of locally produced foods and (4) residing in agricultural communities can be beneficial to mental health. Participants recognize that diet influences mental health through physiological, social, and structural pathways, but this connection is threatened by rising dependence on imported, processed foods. Along with complementary quantitative research, the findings highlight the potential of expanding nutritional health literacy and clinical guidance and strengthening local food systems and traditional diets for mental well-being among Caribbean Small Island Developing States.\n\nID: 42110082\nTitle: Racial and Socioeconomic Disparities in Sudden Unexpected Infant Death in the United States: A Population-Based Analysis Using Linked Birth-Infant Death Data.\nAbstract: Sudden unexpected infant death (SUID) remains an important contributor to infant mortality in the United States. Previous national surveillance reports have documented differences in mortality across racial, socioeconomic, and birth-related characteristics. Continued examination of these patterns using national vital statistics data is important for understanding population-level disparities and informing prevention strategies. \u00a0To quantify disparities in SUID\u00a0in the United States through 2023 by examining social determinants, including race, ethnicity, and maternal education, alongside clinical characteristics such as birth weight and gestational age. A descriptive cross-sectional study was conducted using the Linked Birth Infant Death dataset accessed through the CDC Wide-Ranging Online Data for Epidemiologic Research system. The study included aggregated national data from 2007 to 2023, representing 66,381,536 live births and 61,594 SUIDs. Maternal age, maternal education, maternal race and ethnicity, birth weight, and gestational age were examined. Mortality rates were calculated as deaths per 1,000 live births within each category.\u00a0 Results: Higher mortality rates were observed among infants born to younger mothers and mothers with lower educational attainment. Mortality also varied across racial and ethnic groups, with higher rates among infants born to non-Hispanic Black mothers. Birth-related characteristics showed similar patterns, with higher rates among infants with low birth weight and earlier gestational age. This study highlights persistent disparities in SUID across maternal demographic and birth-related characteristics in the United States. Continued public health efforts focused on safe sleep education, maternal health, and targeted prevention strategies may help address these disparities.\n\nID: 42017742\nTitle: SIDS; bed sharing and passive smoking, the leading causes in Pakistan- Letter to the Editor.\nAbstract: \n\nID: 42003135\nTitle: A motor thalamic site in humans that suppresses involuntary breathing without awareness.\nAbstract: Breathing is generated by brainstem respiratory networks but can be controlled and modulated by forebrain activity. The recent clinical adoption of thalamic electrode implantation during intracranial electroencephalography (iEEG) provides a rare opportunity to examine the role of the human thalamus in respiratory control. Here, we tested whether thalamic stimulation alters breathing in 11 patients undergoing iEEG for epilepsy monitoring. Across 412 stimulation trials at 108 thalamic sites, thalamic stimulation induced central apnea in every participant. Apnea occurred in isolation without sensory or motor effects and without awareness of breathing cessation. Apnea occurred with stimulation of either the right or left thalamus and was observed across all ages, including participants as young as 22 mo. Volitional breathing and speech were preserved, indicating that respiratory motor pathways remained functional. In contrast, except for the amygdala, stimulation of other forebrain regions, including the hippocampus, insula, cingulate, and frontal, temporal, and parietal cortices, did not affect breathing. Respiratory inhibition depended on thalamic location, occurring most consistently with stimulation of the ventral lateral anterior (VLa) and ventral anterior (VA) nuclei. A machine learning algorithm localized the focal apneic region within the anterior motor thalamus, centered in VLa and extending into VA. Identification of a focal apneic site in the VLa/VA motor thalamus expands thalamic function, revealing a forebrain node capable of overriding brainstem respiratory control. This circuit may coordinate breathing with volitional behaviors such as speech, and dysfunction of this circuit may play a role in central apnea disorders, including sleep apnea, SUDEP, and SIDS.NEW & NOTEWORTHY This study identifies a focal site in the human motor thalamus where electrical stimulation suppresses involuntary, automatic breathing and induces apnea without awareness. Using intracranial recordings in pediatric and adult patients, we found that this effect localizes to the ventral anterior/ventral lateral anterior nuclei. These findings reveal a previously unrecognized thalamic function in the forebrain control of breathing.\n\nID: 41950602\nTitle: Nursing insights into how maternal anxiety bridges sudden infant death syndrome awareness and parenting self-efficacy among mothers of infants.\nAbstract: Sudden Infant Death Syndrome (SIDS) remains a leading cause of post\u2011neonatal mortality, and maternal awareness of safe sleep practices is essential for prevention. However, maternal anxiety may influence how effectively this awareness translates into confident caregiving. Parenting self-efficacy is a determinant of maternal behavior, yet the mechanisms linking SIDS awareness and self-efficacy remain unclear. To examine the relationship between SIDS awareness and parenting self-efficacy among mothers of infants and to investigate the mediating role of maternal anxiety. A cross-sectional study was conducted among 335 mothers of infants aged 0-12\u00a0months attending six primary healthcare facilities in Mansoura, Egypt. Data were collected using validated scales that measure SIDS awareness, postpartum anxiety, and parenting self-efficacy. Pearson correlations, mediation analysis, and multiple linear regression were performed. SIDS awareness was positively associated with parenting self-efficacy (r\u00a0=\u00a00.57, p\u00a0<\u00a00.001) and negatively associated with maternal anxiety (r\u00a0=\u00a0-0.18, p\u00a0<\u00a00.001). Anxiety was inversely related to self-efficacy (r\u00a0=\u00a0-0.31, p\u00a0<\u00a00.001). Mediation analysis revealed that maternal anxiety partially mediated the relationship between SIDS awareness and parenting self-efficacy. Nurse-led care should combine safe sleep education with routine screening and management of maternal anxiety. Reassurance-focused communication and brief psychosocial support during postnatal visits may strengthen maternal confidence and improve adherence to safe infant care practices. Maternal anxiety partially shapes how SIDS awareness influences parenting self-efficacy. Integrating emotional support with SIDS education may strengthen maternal confidence and improve safe infant care practices.\n\nID: 41796078\nTitle: Neuropathologic findings and age-related differences in Finnish pediatric medico-legal autopsies.\nAbstract: Neuropathological examination plays a critical role in medico-legal cause-of-death investigation, especially in determining the cause and manner of death in pediatric autopsies. Although a comprehensive neuropathological examination is recommended, limited data exists of the diagnostic yield of neuropathology consultations in such cases. This retrospective register-based study reviewed Finnish pediatric medico-legal autopsies from 2016 to 2022 involving full neuropathological examination performed by a neuropathologist, with a focus on age-related differences in consultation rates, themes, and diagnostic findings. Data were retrieved from the medico-legal cause-of-death investigation documents, and included background characteristics, neuropathologic diagnoses, and causes and manners of death. A total of 118 pediatric medico-legal autopsies with a neuropathology consultation were performed during the study period. The consultation rate was highest among infants (aged <1\u2009year; 45.6%), compared to early childhood (aged 1-10\u2009years; 23.0%) and late childhood (aged 11-18\u2009years; 6.2%). Traumatic brain injury was the most frequent consultation theme overall (33.9%), while the frequency of epilepsy-related consultations increased with age. Hypoxic-ischaemic neuronal injury constituted the commonest finding, with an overall prevalence of 43.2%. Findings associated with childhood epilepsy were more prevalent in early and late childhood, with epilepsy accounting for 15.2% of deaths in the latter group. Positive diagnostic findings were uncommon among infants, consistent with a high proportion of cases (42.1%) classified as sudden infant death syndrome. These findings provide forensic pathologists with age-specific diagnostic insights, supporting more targeted resource use and neuropathology consultation practices.\n\nID: 41763901\nTitle: Strengthening peer support for families bereaved by sudden unexpected infant death: Development and evaluation of a standardized training course.\nAbstract: Sudden Unexpected Infant Death (SUID) is the leading cause of postneonatal mortality worldwide. Bereaved parents commonly seek peer support for bereavement-related needs, but competencies and standardized training for organizations offering peer facilitators are lacking. We developed and piloted a train-the-trainer curriculum addressing peer facilitators' knowledge, skills, and attitudes for supporting SUID-bereaved parents. A needs assessment of international peer support organizations and expert consensus from an international working group informed development of competencies and a curriculum. A 1.5-day in-person pilot of eight participants from five countries was conducted, followed by remote sessions. Pre- and post-training surveys assessed impact. Wilcoxon signed-rank tests analyzed outcomes; open-ended responses were descriptively summarized. Significant improvements in knowledge, skills, and attitudes (p < .05) were shown across 13 competencies, including grief literacy and group facilitation skills, suggesting the curriculum is feasible, acceptable, and effective. This train-the-trainer model may support scalable, global peer bereavement training.\n\nID: 41758359\nTitle: Infant Sleep Behavior Practices and Knowledge of Fathers: An Exploratory and Descriptive Study.\nAbstract: Sudden unexpected infant death (SUID) is a term for any sudden death occurring under 1 year of age. SIDS (sudden infant death syndrome) is the sudden death of an infant that is unexplained after an investigation and often occurs during sleep or in the infant sleep area. In Indianapolis, 130 infants died in 2022 before their first birthday, and 17% were from SUIDs. Fathers' understanding of infant safe-sleep knowledge and behaviors is mostly unknown. This study aims to describe fathers' infant safe-sleep knowledge and behaviors. Study participants were recruited via promotional flyers from 2019 to 2024. Volunteers completed a survey on their infant safe-sleep knowledge and behaviors. Responses were entered via secure, web-based data-collection tool either directly by QR code accessible survey or manually by the research team. Frequency and comparative analyses were performed, and results described. Eighty-five fathers completed the survey. The lowest reported knowledge for safe-sleep practices was for breastfeeding, and wearable blankets being protective against SUID. A smaller percentage of fathers reported their baby never slept in the same bed as someone else and similarly reported never placing their baby to sleep in an adult bed. Fewer fathers correctly reported practicing room-sharing and pacifier usage. Interactive learning geared toward male caregivers on AAP recommendations for preventing sleep-related deaths is key. Focusing efforts with fathers on the risk of soft bedding, benefit of breastfeeding, pacifier usage, and room-sharing will be important to lowering SUID rates and helping men in their role as fathers.\n\nID: 41736199\nTitle: Analysis of First and Second Sleep Environments in Unexplained Sudden Deaths in Infants Based on Scene Reenactment Data.\nAbstract: The American Academy of Pediatrics (AAP) recommends that a safe sleep environment consist of an infant lying supine on a separate, uncluttered, approved sleep surface. Infant awakenings may lead to moving the infant from the initial sleep environment to a second one. The Connecticut Office of the Chief Medical Examiner electronic database was searched from 2018 through 2022 for infant deaths with non-homicidal manner in which scene reenactments were performed; 87 such deaths were identified. The most common causes of death were unsafe sleep environments (64.4%) and asphyxia (21.8%). Of the total cases, 79.3% had a single sleeping environment and 20.7% involved a second. Of the second sleep environments, 77.8% were less safe than the initial sleep environment and 21.8% had evidence of airway obstruction when found unresponsive. Only 4.6% of the infants were in a recommended sleep location at any time during the last sleep. Infant awakenings do not often lead to movement to a second sleep environment, but when they do, the second environment is often less safe than the first. This study reinforces the importance that the sleep environment plays in infant deaths and that scene reenactments play in their investigation.\n\nID: 41724190\nTitle: Sudden Unexpected Infant Death in Inclined Sleepers: 2009-2023.\nAbstract: In 2019, the Consumer Product Safety Commission (CPSC) recalled inclined sleepers following reports of infant deaths. In 2023, recalls were reannounced after additional reports of infant deaths. This study used child death review (CDR) data to describe sudden unexpected infant deaths (SUIDs) that occurred in inclined sleepers. We identified SUIDs that occurred in inclined sleepers from 2009 to 2023 from the Pediatric National Fatality Review-Case Reporting System (Pediatric NFR-CRS). Frequencies and proportions were calculated to describe demographic, incident, and supervisor characteristics. From 2009 to 2023, 158 SUIDs occurred in inclined sleepers. One hundred and eight deaths (68%) occurred from 2009 to 2019; 50 deaths (32%) occurred after 2019. Most infants were younger than 4 months (67%). Most incidents occurred at the infant's home (86%) under the supervision of a parent (83%). Nearly 30% were reported as placed supine to sleep and subsequently found unresponsive nonsupine. In 51 deaths (32%), the CDR team indicated the infant's airway was obstructed when found: 55% by the inclined sleeper material and 35% by other soft bedding in the sleep environment (not mutually exclusive). Infant deaths occurred in inclined sleepers even after the CPSC issued manufacturer recalls in 2019. Health care providers, home visitors, health insurers, and family-serving organizations should continue advising caregivers on the importance of a safe infant sleep environment, including use of a firm, noninclined surface, and avoidance of soft bedding. Improved dissemination of recalls of infant products that represent unsafe sleep environments may reduce the risk of sleep-related deaths.\n\n\n\nID: 41650217\nTitle: Probabilistic mapping and automated segmentation of human brainstem white matter bundles.\nAbstract: Brainstem white matter (WM) bundles are essential conduits for neural signals that modulate homeostasis and consciousness. Their architecture forms the anatomic basis for brainstem connectomics, subcortical circuit models, and deep brain navigation tools. However, their small size and complex morphology, compared to cerebral WM, makes mapping and segmentation challenging in neuroimaging. As a result, fundamental questions about brainstem modulation of human homeostasis and consciousness remain unanswered. We leverage diffusion MRI tractography to create BrainStem Bundle Tool (BSBT), which automatically segments eight WM bundles in the rostral brainstem. BSBT performs segmentation on a custom probabilistic fiber map using a convolutional neural network architecture tailored to detect small anatomic structures. We demonstrate BSBT's robustness across diffusion MRI acquisition protocols with in vivo scans of healthy subjects and ex vivo scans of human brain specimens with corresponding histology. BSBT also detected distinct brainstem bundle alterations in patients with Alzheimer's disease, Parkinson's disease, multiple sclerosis, and traumatic brain injury through tract-based analysis and classification tasks. Finally, we provide proof-of-principle evidence for the prognostic utility of BSBT in a longitudinal analysis of traumatic coma recovery. BSBT creates opportunities for scalable mapping of brainstem WM bundles and investigation of their role in a broad spectrum of neurological disorders.\n\nID: 41612838\nTitle: Development of an educational intervention program for infant safe sleep practices in Korea: a methodological study.\nAbstract: Education on infant safe sleep practices has been known to reduce the risk of sleep-related sudden unexpected infant death. Since sleep environments may vary across sociocultural contexts, infant safe sleep education needs to reflect specific sociocultural settings. This study aimed to develop an educational Protocol for Infant Safe Sleep (PISS) for primary caregivers in Korea that considers parenting behaviors and cultural characteristics. This study was conducted in three key methodological steps: (1) retrieval, defining, and systematic classification of PISS content; (2) the structural formulation of the content as an educational protocol; and (3) content validation. For the first step, a literature review was conducted, along with an analysis of educational materials from institution websites related to infant safe sleep and online parenting communities. Field observations were also conducted to identify relevant Korean culture characteristics. Based on these findings, the PISS was developed. Content validity index was assessed by six professionals, and the results were reflected into the educational program. The PISS intervention provided an educational video and booklet and enhanced learning via phone counseling and educational kit, which comprised an illustrated safe sleep sticker and a calendar-style activity diary. The educational content consisted of (1) sleep location, (2) sleep position, (3) bedding, (4) clothes and temperature, and (5) other considerations. This study developed the PISS, an intangible educational intervention based on Korean sociocultural characteristics and specific guidelines for primary caregivers. Future research should evaluate the effectiveness of this program in promoting safe sleep practices.\n\nID: 41582236\nTitle: Characteristics of infant deaths with positive hair toxicology.\nAbstract: Sudden Unexpected Death in Infancy (SUDI) is the term given to all unexpected infant deaths, comprising accidental, non-accidental and natural deaths including Sudden Infant Death Syndrome (SIDS). As in other developed countries, Australian SUDI rates are relatively low, but incidence rates have remained essentially unchanged since 2004. To increase our understanding of these deaths, we reviewed a cohort of SUDI cases with positive hair toxicology, focussing on toxicology results, pathology findings, and SIDS risk factors.\u00a0All infant deaths between 1st January 2014 and 31st of December 2023 with positive hair toxicology in the state of Victoria, Australia, were reviewed for toxicology results, pathology findings and SIDS risk factors.\u00a0A total of 99 infant deaths met the selection criteria. At least one SIDS risk factor was reported in every case, with a median of 5 per case, highlighting that these infants likely had a high cumulative risk for SIDS. Co-sleeping was most common, reported in over 75% of cases. Polysubstance use was high (87%), with a median of 4 drugs detected per case. Methylamphetamine was detected in hair in over half of cases (n\u2009=\u200957, 58%). Postmortem findings including serious illnesses, like pneumonia (p\u2009=\u20090.002), significant neuropathology (p\u2009=\u20090.002 and p\u2009=\u20090.035), low head circumference (<\u200915th percentile) (p\u2009=\u20090.035) and low body weight (<\u200915th percentile) (p\u2009=\u20090.022 and p\u2009=\u20090.011) were all positively correlated with drug exposure in hair.\u00a0Infants with positive hair toxicology appear to have a high cumulative risk for SIDS, which may reflect a chaotic home environment. Most postmortem findings were positively correlated with drug exposure.\n\nID: 41515176\nTitle: Diet and Mental Health Relationships in Caribbean Populations: A Scoping Review and Evidence Gap Map.\nAbstract: Background/Objectives: Most research linking diet and mental health outcomes is from high-income countries, limiting insight into how these relationships manifest in culturally diverse, vulnerable contexts, such as the Caribbean. This scoping review aims to map existing research on the relationship between aspects of diet and mental health within Caribbean populations, to identify evidence gaps and guide future research. Methods: Eleven databases were searched for studies published between 2000 and 2024 in 33 Caribbean countries which assessed the relationship between diet and mental health outcomes. Duplicate screening and extraction were conducted using Redcap software, and a narrative synthesis and evidence gap map were created. The original protocol was registered with Open Science Framework. Results: Forty-four records were included, nine of which focused on eating disorders (examined separately). Most were cross-sectional studies of the general population, with few experimental and qualitative studies. Surveys were the most frequently applied data collection tool, often without mention of local adaptation or validation. Most records examined food security and depression as their 'diet' and 'mental health' variables, respectively. Frequently explored relationships included autism and seafood intake and fruit and vegetable intake, while depression and food security was the most widely examined relationship across studies. Conclusions: Caribbean research on diet-mental health relationships is growing though it is limited in scope, design, and cultural validity. Strengthening this evidence base requires studies whose primary aim is in nutritional psychiatry, using culturally relevant tools, and an expansion of study designs that incorporate Caribbean food systems and sociocultural contexts surrounding diet and mental health.\n\nID: 41508915\nTitle: Reelin in the Infant Hippocampus, and Relationship to Sudden Infant Death Syndrome (SIDS) and Dentate Gyrus Morphology.\nAbstract: Morphological features within the hippocampal dentate gyrus (DG) granule cell layer (GCL) have been identified in some cases of sudden unexpected infant death (SUDI), including sudden infant death syndrome (SIDS). Reelin, an extracellular matrix protein, is critical in neuronal migration and cell positioning. An altered reelin expression is hypothesized as a contributor to altered DG morphology. This study aimed to determine whether the number of reelin-expressing cells within the infant hippocampus is altered in (1) SIDS, and according to the presence of (2) SIDS risk factors (age, cigarette smoke exposure [CSE], sleep position, bed sharing, and upper respiratory tract infection [URTI]), and (3) DG morphology. Immunohistochemical staining of reelin was quantified (measured as the number of positive reelin cells/mm2) within the layers of the DG, CA4/Hilus, CA3-CA1, and subiculum in cases of explained SUDI (eSUDI, n\u2009=\u200912), SIDS I (n\u2009=\u20097), and SIDS II (n\u2009=\u200933). Reelin was highly correlated with age. After adjusting for age, SIDS II infants had a lower number of reelin immunopositive cells in the CA1, a finding that was more pronounced in bed sharers. Analysis of risk factors indicated lower reelin in the DG and CA3 of males, and in the DG of infants with URTI (when excluding bed sharers). The presence of the DG morphological feature of cluster ectopic cells was associated with a lower number of reelin cells across several hippocampal layers, whereas gaps were associated with higher numbers, with layers predominantly affected being the DG molecular layer and CA2 stratum radiatum.\n\nID: 41501081\nTitle: Multi-access edge computing scheduling optimization model for remote education under 6G network environment based on reinforcement learning.\nAbstract: The evolution of digital education necessitates robust computational frameworks to address the complexities inherent in remote learning environments. Traditional scheduling mechanisms often fall short in accommodating the dynamic nature of learner engagement and the asynchronous delivery of content. To bridge this gap, we introduce a novel computational model that leverages reinforcement learning to optimize content delivery schedules. Central to our approach is the Attentive Stochastic Transition Estimation Network (ASTEN), which models the probabilistic transitions of learner states, accounting for factors such as attention variability and feedback delays. Complementing ASTEN is the Selective Informative Delivery Strategy (SIDS), a decision-theoretic framework that determines optimal content emission based on real-time uncertainty assessments and pedagogical utility. Our approach captures nuanced behavioral trends, such as sporadic learner interaction, temporal learning decay, and individualized attention cycles, thereby enabling a more responsive and tailored instructional strategy. By explicitly integrating cognitive and behavioral signals within the scheduling framework, our model facilitates the delivery of content that aligns with each learner's evolving state. Empirical evaluations demonstrate that our integrated model significantly enhances learning outcomes by adapting to individual learner trajectories and mitigating the challenges posed by sparse feedback. This research contributes to the theoretical foundations of computational learning models and offers practical insights for the development of adaptive educational technologies, particularly in environments where traditional one-size-fits-all approaches prove inadequate.\n\nID: 41475408\nTitle: Sudden Unexpected Infant Death and Safe Sleep Practices.\nAbstract: Sudden unexpected infant death (SUID) is the primary cause of post-neonatal mortality. SUID disproportionately affects preterm infants and infants admitted to the neonatal intensive care unit (NICU). NICU providers are charged with ensuring the implementation of safe sleep practices and caregiver education while balancing other acute medical needs. The persistent lack of improvement in sleep-related infant deaths and the release of updated recommendations from the American Academy of Pediatrics (AAP) have reinvigorated institutional and public health efforts to reduce SUID. In\u00a0this review, we will discuss the nomenclature, epidemiology (including racial and ethnic disparities in SUID), and pathophysiology of sleep-related infant deaths. Finally, we will review the updated AAP recommendations on safe sleep and early transition to safe sleep in the NICU.\n\nID: 41439835\nTitle: Designing Infant Mattresses Tailored to Developmental Sleep Characteristics: A Comprehensive Review.\nAbstract: This paper reviews existing research on infant mattress design to promote safe and comfortable sleep and proposes evidence-based design recommendations. Focusing on safety related to Sudden Unexpected Infant Death (SUID) and comfort associated with infant development and thermoregulation, we examine mattress firmness, pressure distribution, breathability, and thermal properties. Since infants have difficulty turning over and possess immature thermoregulatory functions, mattress characteristics directly influence sleep quality and safety. Based on international studies, we clarify the requirements for infant mattresses and provide insights into future product development and evaluation standards.\n\nID: 41422643\nTitle: Abandoned, lost and otherwise discarded fishing gear in the Caribbean SIDS of Trinidad and Tobago.\nAbstract: Abandoned, lost and otherwise discarded fishing gear (ALDFG) is a contributor to marine plastic debris in the Caribbean. This study focused on ALDFG in the Caribbean Small Island Developing State (SIDS) of Trinidad and Tobago, by exploring the problem, its causes and the existing management framework to inform evidence-based interventions. The specific objectives were to estimate the amount of plastic waste entering the coastal/marine environment as a result of ALDFG, identify hotspots of ALDFG accumulation, determine the causes of fishing gear loss, document practices used by fishers to avoid gear loss, explore fishers' perceptions of ALDFG and assess the legislative, regulatory and policy gaps in the management of ALDFG. We find that gillnets, hooks and lines, traps and fish aggregating devices (FADs) used in artisanal fisheries in Trinidad and Tobago can get lost and enter the environment. This lost gear is likely to end up in the Exclusive Economic Zone (EEZ) of neighbouring Caribbean States. The causes of gear loss and damage were identified as a combination of conflict-based (high traffic of other vessels, conflict with other gear, vandalism) and environmental (gear snagged on obstructions, damage or towing by large animals, strong currents) factors. A suite of interventions (prevention, mitigation, remediation) is available to address the issue. Given its transboundary nature, national, regional and international action is crucial.\n\nID: 41420984\nTitle: Generation of iPSC lines (UMILi032-A, UMILi033-A, UMILi034-A, UMILi035-A, UMILi036-A) from five Congenital Central Hypoventilation Syndrome patients carrying different poly-alanine expansion mutations in the PHOX2B gene.\nAbstract: Congenital Central Hypoventilation Syndrome (CCHS) is a rare, life-threatening genetic disorder of the autonomic nervous system characterized by alveolar hypoventilation and generalized dysautonomia. CCHS is caused by heterozygous PHOX2B mutations, predominantly polyalanine repeat expansion (95% of cases) and, less frequently, frameshift mutations (5%). To address the lack of disease models, we generated five human induced pluripotent stem cell (hiPSC) lines derived from patients carrying\u00a0+5Ala, +6Ala and\u00a0+11Ala expansion mutations. These hiPSC lines exhibited undifferentiated hPSC phenotype, pluripotency, normal karyotype, and retention of the pathogenic genotype, providing a reliable in vitro platform for elucidating CCHS molecular mechanisms and disease pathogenesis.\n\nID: 41416934\nTitle: \"Whose mother am I?\" Maternal identity reconstruction among bereaved mothers of infants who died of SIDS.\nAbstract: The term sudden infant death syndrome (SIDS) refers to the unexpected and medically unexplained death of an infant, typically during sleep. This study examines how maternal identity is reconstructed among 14 Jewish Israeli mothers who experienced the loss of a baby to SIDS. We began with the assumption, well-grounded in modern grief models, that loss undermines the bereaved identity and in the case of SIDS the undermine of maternal identity is likely to be intensified due to the perceived failure to protect the infant, the ambiguity of a medically unexplained death, and often the dismissive societal responses. Drawing on in-depth semi-structured interviews and employing a narrative analytic approach, the findings reveal that reconstruction of maternal identity is a dynamic, non-linear process that oscillates across three dimensions adapted from Van Gennep's rites of passage framework: separation, liminality, and integration. The third dimension is conceptualized as a continuum ranging from a split maternal identity to a more integrated sense of self - a unified maternal identity. Implications for mental health professionals supporting bereaved mothers are discussed.\n\nID: 42477847\nTitle: Violations of the breast milk substitutes act-2013 and its rules\u2009-\u20092017 in Bangladesh.\nAbstract: Inadequate breastfeeding practices increase the risk of mortality and morbidity among infants and young children. Recent global estimates suggest that inadequate breastfeeding is responsible for approximately 16% of child deaths worldwide each year, highlighting the ongoing need to strengthen support systems to improve infant and young child feeding practice in Bangladesh, 55% of infants under six months of age are exclusively breastfed. To improve breastfeeding rates and reduce infant mortality, the Government of Bangladesh enacted the Breast-milk Substitute (BMS) Act, 2013, and its Rules in 2017 to regulate the marketing of breast-milk substitutes. The study aimed to assess violations of the BMS Act, 2013, and Rules, 2017, focusing on the types, actors, and settings of such violations, while also raising awareness of the Act among key stakeholders and the public. We carried out a cross-sectional survey among 818 retail outlets and pharmacies; 969 baby-friendly hospitals; 969 doctors, nurses, and other health professionals; and 315 mothers with children aged 0-24 months across eight divisions of Bangladesh from August 2016 to December 2019. Data were collected through structured interviews, direct observations, and document reviews using a modified International Baby Food Action Network-International Code Documentation Centre (IBFAN-ICDC) protocol and the BFHI Hospital External Assessment Tool. All retail outlets surveyed (n\u2009=\u2009818) sold unregistered BMS products, and all displayed promotional materials. These retail outlets also sold BMS products labeled with health and nutrition claims. In hospitals, 25.5% of doctors (n\u2009=\u2009247) and 21.3% of nurses and other health professionals (n\u2009=\u2009206) promoted BMS without medical indication. Additionally, 32.0% of health facilities (n\u2009=\u2009300) reported providing financial incentives to health professionals to participate in events sponsored by BMS manufacturers. Furthermore, BMS manufacturers violated the BMS Act, 2013 by establishing breastfeeding corners in 164 hospitals (17.5%). This study identified extensive violations of the BMS Act 2013 and its Rules 2017 in Bangladesh, revealing unethical promotion and distribution of BMS. Health professionals in BFHI-trained hospitals played a significant role in these breaches, contributing to the erosion of breastfeeding practices. Urgent monitoring and enforcement are needed to protect infant health and uphold national regulations.\n\nID: 42473973\nTitle: Sudden Unexpected Death in Infancy in New Zealand: A Review of Coronial Recommendations.\nAbstract: Sudden Unexpected Death in Infancy (SUDI) remains a leading cause of post-neonatal mortality in Aotearoa New Zealand. We analysed New Zealand coronial findings and recommendations to identify recurring modifiable risks, social determinants of health, and system-level failures that might inform prevention strategies. A structured thematic synthesis was conducted on 127 New Zealand coronial findings and recommendations released between 2012 and 2025. Data were abstracted on infant demographics, sleep environments, caregiver factors, socioeconomic determinants, and the nature of specific coronial recommendations. Bed sharing was present in 81% (n\u2009=\u2009103) of cases. Maternal smoking was documented in 34 cases. Deaths clustered in early infancy, with 50% occurring before 3 months of age. Social complexities, including overcrowding, damp housing, and financial hardship, contributed to the sleep environment in 60% of cases (n\u2009=\u200976). Coroners issued 22 distinct types of recommendations targeting systems-level rather than just individual change. Findings show that sudden infant deaths are complex, with contributing factors operating at many levels and not simply due to parent's failure to follow prevention advice. SUDI prevention must shift from parental messaging to include multi-level interventions that address structural poverty, prioritised provision of in-bed sleepers, agency accountability, and mandatory workforce training.\n\n\n\nID: 42441887\nTitle: First Brazilian birth after Preimplantation Genetic Testing for Severe Methylmalonic Acidemia: preventing sudden infant death.\nAbstract: Methylmalonic acidemia (MMA) is a rare autosomal recessive metabolic disorder caused by pathogenic variants in the MMUT gene, often associated with severe neonatal manifestations and sudden unexpected death in infancy (SUDI). Preimplantation Genetic Testing for Monogenic Diseases (PGT-M) offers a valuable reproductive option for at-risk couples seeking to prevent transmission of such conditions. This represents the first Brazilian case of a healthy birth following combined PGT-M and PGT-A for MMA known. After the neonatal loss of their first child due to mut0-type MMA, a couple underwent genetic testing, which identified compound heterozygosity in MMUT: a maternal deletion (c.1196_1197del) and a paternal duplication (c.213_216dup). Haplotype construction used parental and proband DNA. Two IVF cycles yielded 13 blastocysts; of these, one embryo was diagnosed as being both euploid and unaffected, and two were euploid and heterozygous carriers. One of those embryos was selected for transfer, resulting in an uneventful pregnancy and the live birth of a healthy female infant. This single case highlights the clinical utility of PGT-M to prevent the recurrence of a severe inborn errors of metabolism and underscores the importance of early genetic counseling in couples with prior adverse neonatal outcomes.\n\nID: 42419738\nTitle: Impacts of Paid Family Leave on Perinatal Health: A Nationwide Quasi-Experimental Study.\nAbstract: The United States remains the only high-income nation without a national paid family leave (PFL) policy. It also has persistently high maternal and infant mortality rates. Understanding PFL impacts on perinatal health is critical. We determined the impact of state PFL policies on perinatal health, with additional focus on socioeconomic disparities. We analyzed live singleton births using 2016 to 2022 birth certificate data (N = 11\u2009452\u2009411). We conducted a quasi-experimental analysis using heterogeneity-robust differences in differences, comparing pre-post trends in a comprehensive set of perinatal outcomes in jurisdictions with (Connecticut; Washington, DC; Massachusetts; New York; and Washington) and non-South states without PFL. Analyses were additionally stratified by maternal race and ethnicity, education, insurance, and Special Supplemental Nutrition Program for Women, Infants, and Children participation and adjusted for individual- and state-level time-varying covariates. Hypertensive disorders of pregnancy risk decreased by 13% following PFL implementation, as did excess gestational weight gain. PFL implementation was associated with modest increases in small for gestational age (0.290 percentage points [pp]; 95% CI, -0.300 to -0.102), preterm birth (0.590 pp; 95% CI, 0.465-0.715), and lower mean birthweight (-5.205\u2009g; 95% CI, -7.096 to -3.314). Socioeconomically disadvantaged subgroups saw higher risks of adverse birth outcomes but improved maternal outcomes. This study adds to prior research that found that PFL is associated with improvements in parental health and breastfeeding in the United States. Our findings suggest that state PFL policies had mixed impacts on perinatal health; further investigation of policy parameters and mechanisms is warranted.\n\nID: 42405008\nTitle: Sally Clark: Trial and error by Judge and Jury.\nAbstract: Sally Clark's 1999 conviction for the murder of her two infant children represented one of the most conspicuous miscarriages of justice in modern English criminal law. A central component of the prosecution case was statistical evidence presented by Professor Sir Roy Meadow, which suggested that the probability of two sudden infant deaths occurring naturally within the same family was approximately one in 73 million. This paper examines three methodological limitations that affect the evidential value of that estimate. First, the family characteristics used to reduce the estimated probability of natural death were not considered in relation to the probability of the alternative explanation, thereby distorting comparative inference. Second, sudden infant death syndrome is a diagnosis of exclusion; population frequency data derived from such a category cannot determine causation in an individual case and are contingent on the limits of postmortem investigation. Third, the probability estimate was presented without reference to the likelihood of competing explanations, limiting its interpretive value. The paper further argues that the significance of the Clark case lies not only in the arithmetical error in the one in 73 million figure but in the broader evidential process by which probabilistic evidence was admitted, framed and interpreted within a criminal trial. The paper also examines the empirical and unstructured approach of English criminal courts to expert evidence. It considers the extent to which subsequent developments, including the Criminal Practice Directions 2023, respond to these difficulties, and compares that position with the contrasting procedural framework associated with the Daubert standard in the United States. The analysis situates the Clark case within broader issues concerning the interpretation, contextualisation and scrutiny of expert evidence in legal proceedings.\n\nID: 42404096\nTitle: Integrating immediate Kangaroo Mother Care as an integral part of small and sick newborn care in facilities with level 2 Special Newborn Care Units: Implementation Research Protocol.\nAbstract: Immediate Kangaroo Mother Care (iKMC) involves the initiation of skin-to-skin contact (SSC) between the mother (or an additional caregiver) and preterm and/or LBW infants within the first hours of birth, with exclusive breastfeeding. While KMC has traditionally been initiated after the infant stabilizes, immediate initiation of SSC has proven more effective in reducing neonatal mortality. However, despite its proven benefits, the adoption of immediate KMC remains a challenge. This study aims to develop and test an implementation model for integrating immediate KMC into the routine care of small and sick newborns in level 2 Special Newborn Care Units (SNCUs) in Bangladesh, Ethiopia, India, and Nigeria. This multicountry implementation research study will develop and evaluate a scalable model for integrating iKMC into newborn care across six study sites in four countries. The study will involve developing and optimizing an implementation model using a mixed-methods design, combining both qualitative and quantitative approaches. Formative research will be conducted to identify barriers and facilitators to the effective implementation of iKMC, guiding the development of the initial model. The study will benefit from concurrent programme learning, using both qualitative insights and outcome measurements, to iteratively refine the model and ensure high-quality, widespread implementation of iKMC. The study will provide insights into the effective integration of iKMC into existing health systems, addressing key challenges in low-resource settings. Findings will inform scalable strategies for widespread implementation, contributing to global efforts to enhance newborn care and reduce neonatal mortality.\n\nID: 42379716\nTitle: Development and internal validation of a neonatal mortality risk prediction model for low birthweight neonates in public hospitals, North-West Ethiopia: a prospective follow-up study.\nAbstract: This study aimed to develop and internally validate a neonatal mortality risk prediction model for low birthweight (LBW) neonates in public hospitals of North-West Ethiopia. An institution-based prospective follow-up study. The study was conducted in seven hospitals, comprising three general hospitals and four primary hospitals, between 14 February and 31 October 2025. The general hospitals, Injibara, Finote Selam and Pawi, provide level II neonatal intensive care services, whereas the primary hospitals, Dangila, Chagni, Jawi and Gimja Bet, provide level I newborn care services. These hospitals are situated in the Awi, West Gojjam and Metekel zones of the Amhara and Benishangul Gumuz regions in north-western Ethiopia. 955 LBW neonates were enrolled in the study. Neonates born outside health facilities were excluded if their birth weight was unknown, particularly those delivered by traditional birth attendants, as were neonates whose first recorded weight was obtained more than 24 hours after birth. Participants were selected using consecutive sampling and data were collected electronically using the KoboCollect mobile application. Data were analysed using R software V.4.4.3. Least Absolute Shrinkage and Selection Operator regression and multivariable logistic regression were used to identify predictors and develop a simplified risk score and nomogram. Model performance was evaluated in terms of discrimination and calibration, while internal validation was performed using bootstrapping. The clinical utility of the model was assessed using decision curve analysis (DCA). The final model included nine predictors: sepsis, perinatal asphyxia, respiratory distress syndrome, absence of exclusive breastfeeding, absence of Kangaroo Mother Care, gestational ages of 28 weeks to <32 weeks and 32 weeks to <37 weeks, and birth weights of <1000 g and 1000-1499 g. The original model demonstrated good discrimination, with an area under the curve of 84.2% (95% CI 81.5% to 86.9%). After internal validation, the simplified risk score and nomogram achieved areas under the curve of 83.85% and 83.5%, respectively. The model showed excellent calibration before and after validation. DCA indicated that the model provides meaningful clinical benefit. The nomogram and simplified risk score demonstrated excellent calibration and good discriminatory performance. Their application in clinical settings may improve early intervention and potentially reduce neonatal mortality in Ethiopia by enabling rapid, individualised mortality-risk prediction among LBW neonates. However, external validation in different settings is required.\n\nID: 42297410\nTitle: 2025 Korean Guidelines for Cardiopulmonary Resuscitation: Part 7. Pediatric basic life support.\nAbstract: Pediatric cardiac arrest primarily arises from asphyxia in infants and trauma in older children, contrasting with adult etiologies dominated by cardiac events. This underscores prevention as the cornerstone of pediatric basic life support, through injury mitigation like child restraint systems and water supervision, safe sleep practices including supine positioning on firm surfaces with caregiver smoking cessation to reduce sudden infant death syndrome, plus awareness of child abuse and adolescent suicide prevention. In hospitals, pediatric early warning systems (PEWS) enable early deterioration detection via vital sign scoring for timely intervention. Major updates in the 2025 pediatric basic life support guidelines reflect evidence-driven refinements. First, hospitals should implement PEWS to prompt rapid response teams for at-risk inpatients. Second, all rescuers (lay and healthcare providers) should employ the two-thumb encircling hands technique for infant chest compressions for optimal depth (about 4 cm), rate (100-120/min), and recoil; one-hand heel compression serves as backup if infeasible. Third, lay rescuers may apply automated external defibrillators for nontraumatic out-of-hospital cardiac arrest in children aged 1 year or older, prioritizing prompt attachment after initial cardiopulmonary resuscitation (CPR) cycles to address potential shockable rhythms. Fourth, for infant foreign body airway obstruction, alternate five back blows (over the spine between scapulae) with five chest thrusts (using heel-of-hand on sternum) until cleared or unresponsive, then transition to CPR. These updates aim to enhance bystander intervention, CPR quality, and survival with favorable neurologic outcomes in pediatric cardiac arrest.\n\nID: 42274943\nTitle: A Decade of Empowerment: Strengthening Safe Sleep Awareness Among Black Birthing People.\nAbstract: To evaluate Black birthing people's knowledge of American Academy of Pediatrics (AAP) infant safe sleep recommendations over time in the context of a substantial, county-wide, tailored public health initiative against infant mortality. This is a nested case-control study within a prospective cohort of N\u2009=\u2009606 adult birthing people who delivered at a single academic medical center between 2011 and 2022. The outcome of interest was knowledge of the AAP infant safe sleep recommendations which was determined by participants demonstrating knowledge of five factors. We separated data according to the bimodal distribution of responses: 2011-2014 and 2019-2022. We used Chi square analysis to evaluate change in demonstrated knowledge of AAP guidelines over time for each race. We utilized binomial logistic regression modeling to determine crude odds ratios and calculated 95% confidence intervals to quantify the relationship between the outcome and demographic variables. We found both the non-Hispanic Black and non-Hispanic White groups significantly increased demonstrated knowledge of AAP recommendations over time (p\u2009=\u2009.01 and p\u2009<\u2009.01 respectively). In the pre-intervention period, non-Hispanic Black birthing people were significantly less likely to demonstrate knowledge than non-Hispanic White birthing people (OR 0.52 95% CI [0.31-0.85]). In the post-intervention period, there was no significant difference in demonstrated knowledge between non-Hispanic Black and non-Hispanic White birthing people (OR 0.36 95% CI [0.13-1.03]). Our results provide insight into the potential impact of robust infant mortality public health initiatives on the awareness of safe sleep recommendations in birthing people within Hamilton County, Ohio.\n\nID: 42261558\nTitle: Determinants of Low Birth Weight in Ghana: Analysis of the 2022 Demographic and Health Survey.\nAbstract: Low birth weight (LBW) remains a significant public health challenge in developing countries, contributing substantially to infant mortality and morbidity. To examine sociodemographic, maternal health, and healthcare utilization factors associated with low birth weight in Ghana. This cross-sectional study analyzed data from 8,581 women 15-49 years from the 2022 Ghana Demographic and Health Survey (DHS). LBW was defined as birth weight <\u20092,500 grams. Logistic regression models were used to identify predictors of LBW. Crude and adjusted odds ratios with 95% confidence intervals were calculated. The prevalence of LBW was 16.8%. The independent predictors of LBW included household poverty (aOR = 1.66), middle-income status (aOR = 1.49), lack of malaria prevention (aOR = 2.77), absence of skilled antenatal care (aOR = 1.71), and lack of iron supplementation (aOR = 1.31). Protective factors were maternal secondary education (aOR = 0.68), advanced maternal age (aOR = 0.74), and overweight BMI (aOR = 0.56). Significant interactions were identified between young maternal age and underweight status (aOR = 2.89). Also, there was an interaction between poverty and lack of malaria prevention (aOR = 0.42). Low birth weight in Ghana is influenced by socioeconomic inequalities, maternal nutritional status, and healthcare access, with synergistic effects between young maternal age and undernutrition. Targeted interventions addressing poverty, maternal nutrition, and ensuring access to skilled antenatal care, iron supplementation, and malaria prevention are essential for reducing LBW prevalence.\n\nID: 42242838\nTitle: Geospatial disparities in infant mortality in Ghana: evidence from national data.\nAbstract: Infant mortality remains a major public health concern in Ghana, with progress occurring unevenly across population groups and locations. Understanding both the determinants and the spatial distribution of infant deaths is essential for designing targeted interventions and reducing persistent inequalities. We analysed nationally representative data from multiple rounds of the Ghana Demographic and Health Surveys, comprising 19\u2009558 infant survivors and 3464 infant deaths. Local Indicators of Spatial Association and kernel density estimation were applied to produce cluster and spatial risk maps, respectively. A shared frailty Cox proportional hazards model, accounting for unobserved heterogeneity at the regional level, was used to estimate adjusted HRs. Infant mortality exhibited significant spatial autocorrelation, while regional quantile maps revealed distinct yet overlapping geographic patterns for both neonatal and infant mortality. Infant mortality showed substantial clustering. Elevated risks were observed in Upper West, parts of Savannah and Ashanti, whereas lower risks were evident in Greater Accra, North East and Eastern regions. Factors associated with lower hazards included tertiary maternal education (adjusted HR (aHR)=0.66; 95%\u2009CI 0.48 to 0.89), health insurance coverage (aHR=0.86; 95%\u2009CI 0.80 to 0.94), early initiation of antenatal care (aHR=0.88; 95%\u2009CI 0.83 to 0.93) and completion of \u22654 antenatal visits (aHR=0.90; 95%\u2009CI 0.82 to 0.98). Socioeconomic gradients were apparent, with infants in relatively richer households experiencing lower mortality hazards. Infant-level characteristics strongly predicted survival, including normal birth weight (aHR=0.60; 95%\u2009CI 0.45 to 0.75), breastfeeding (aHR=0.39; 95%\u2009CI 0.31 to 0.47), longer birth intervals (aHR=0.63; 95%\u2009CI 0.57 to 0.70) and vaccination (aHR=0.42; 95%\u2009CI 0.32 to 0.53). Infant mortality in Ghana displays marked spatial heterogeneity and regional-level effects. Strengthening maternal and newborn services in hot-spot regions, expanding early antenatal and postnatal care and targeting high-risk maternal profiles may accelerate progress toward equitable child survival.\n\nID: 42196581\nTitle: A Case of Sudden Unexpected Infant Death with Presumptive SARS-CoV-2 Infection.\nAbstract: COVID-19 remains a challenge to the global healthcare despite the end of the pandemic, including due to the significant involvement of children in the epidemic process. During the pandemic period, an increase in the incidence of Sudden Unexpected Infant Death (SUID) and Sudden Infant Death Syndrome (SIDS) was observed. Currently, their rates remain elevated compared to the prepandemic period. The pathogenetic mechanisms underlying the fulminant course of infection in infants leading to fatal outcomes remain insufficiently understood. In this study, we report for the first time the results of histological and immunohistochemical examination of the lungs in a case of COVID-19-associated SUID in a 2-month-old infant. The absence of similar studies in the available literature limits opportunities for analyzing the pathogenesis of SUID. Our data allow a detailed characterization of the histological changes in the lungs, the localization and range of SARS-CoV-2 nucleocapsid protein expression, the identification of molecular mechanisms underlying apoptosis in the pulmonary microvascular endothelium, and the elucidation of the role of endothelial dysfunction. Particular attention in this article is devoted to the role of cytokines (IL-6, TNF-\u03b1, and IFN-\u03b3) in the pathogenesis of hyperacute viral infection. The obtained data demonstrate substantial differences between the observed changes and the classic presentation of COVID-19 in older children. These findings offer prospects for improving prevention strategies and developing targeted therapy for fulminant forms of COVID-19, while also contributing to the understanding of SIDS pathogenesis.\n\nID: 42185501\nTitle: Continuous and prolonged breastfeeding in wild Bornean orangutans verified with fecal proteomics.\nAbstract: Orangutans have a slow life history with one of the longest interbirth intervals and the lowest reported infant mortality rates among primates or even mammals. Breastfeeding is a key factor in their life history because it possibly promotes offspring health and increases maternal interbirth intervals. However, quantifying milk intake is difficult, and existing estimates for their weaning age are contradictory. Here, we use fecal proteomics to predict the breastfeeding and weaning patterns in wild Bornean orangutans in Danum Valley, Sabah, Malaysia. Age changes in milk-specific proteins identified from 20 feces of five immature individuals revealed that the orangutans in Danum Valley consistently consumed milk for \u22656.5 years after birth, consistent with the behavioral evidence as having one of the longest breastfeeding periods in mammals. Milk intake was significantly correlated with higher levels of biological defense and probiotic bacterial proteins. Mothers were not pregnant with their next offspring during the breastfeeding period. These results indicate that a continuous and long breastfeeding period is a key component of the slow life history of orangutans and shows that fecal proteomics can be applied to a wide range of wild animal populations, with the potentials to uncover novel aspects of behavior and physiology.\n\nID: 42163233\nTitle: Interpretable prediction of neonatal mortality and its key predictors using machine learning and SHAP analysis.\nAbstract: Neonatal mortality is still a global public health concern, especially in lower- and middle-income countries like Ethiopia. Machine learning (ML) has shown excellent performance in healthcare prediction tasks due to its capability of efficiently handling interactions within mixed-type tabular data. Therefore, this study aimed to develop an interpretable model that can predict neonatal death based on the Ethiopian Demographic Health Survey (EDHS) dataset. This study utilized the imbalanced EDHS dataset collected from all surveys conducted in 2000, 2005, 2011, 2016, and 2019. We evaluated some basic and tree-based ensemble ML algorithms validated with five-fold cross-validation and 80/20 data splitting. Unbalanced, weighted, and SMOTENC class balancing techniques are utilized across both evaluation strategies. The models were compared based on sensitivity and SHAP interpretability with consideration of F1-score and AUC-PR trade-offs. The weighted LightGBM model achieved the highest recall performance (recall\u2009=\u200987.2%) with a slight reduction of F1\u2009=\u200985.3% and PR-AUC\u2009=\u200992.6% by preserving SHAP interpretability. The SHAP analyses indicate that breastfeeding initiation, number of living children, and ANC visits are the top three key predictors. The dependence plot shows positive SHAP values for delayed breastfeeding initiation, no living children, no antenatal care, lower household member size, grand multiparity, male sex, small birth size, twin births, and short preceding birth intervals. The weighted LightGBM model not only had better sensitivity with competitive AUC-PR results but also showed reliable interpretability using SHAP analyses. The model predicted strong neonatal mortality odds associated with delayed breastfeeding initiation, absence of living children, and lack of antenatal care visits. The model also predicted that neonatal mortality would be more likely for low household member size, grand multiparity, male sex, small birth size, twin births, and short preceding birth intervals. Finally, adequate ANC visits and early initiation of breastfeeding were protective and affected survival outcomes for neonates, emphasizing the importance of maternal and newborn healthcare programs.\n\nID: 42135984\nTitle: Current Practices in Postmortem Investigation of Sudden Unexpected Death in Infancy.\nAbstract: To assess postmortem investigations performed in sudden unexpected death in infancy (SUDI) cases in daily practice in France. Children deceased from SUDI and registered in the French SUDI registry from 2015 to 2024 were included retrospectively. The postmortem investigations performed in SUDI cases were described, their temporal trends since 2015 and their compliance with the French National Health Authority guidelines were assessed. The minimum set of non-invasive postmortem investigations performed in cases required to detect unnatural death, including fundus examinations, imaging and toxicological tests, was studied. We examined 1 934 SUDI cases. Laboratory tests were the most frequently performed procedures (93.0%), and fundus examinations were the least frequent (21.6%). There was a significant increase in fundus examinations (9.3% to 31.6%), laboratory tests (87.6% to 97.3%), bacteriological tests (91.4% to 97.2%), toxicological tests (79.0% to 91.0%), and whole-body imaging (75.2% to 87.3%) from 2015 to 2024. Only 2.1% of cases were investigated strictly according to the French guidelines. We found that 13.2% of cases underwent minimal non-invasive postmortem investigation for detecting unnatural death. Although certain investigations are performed more frequently, efforts to improve local protocols and updated guidelines are needed to ensure thorough postmortem investigations, resulting in an improved diagnostic approach.\n\nID: 42068820\nTitle: Analysis of the causes of infant and neonatal deaths in Poznan and neighboring municipalities in Poland in 1998-2024.\nAbstract: Over the last decades, infant mortality has remained at a relatively constant level, with a general downward trend. The identification of the most prevalent causes of death in this population will allow further targeted advancements in healthcare. The aim of this study was to analyze the causes of infant deaths between 1998 and 2024 in the Poznan Metropolitan area. The analysis was performed based on autopsy reports conducted between 1998 and 2024 by the Department of Forensic Medicine of Poznan University of Medical Sciences. The criterion for including the case in the study was death during the first year of life. A total of 155 protocols met the criteria and were included in the study. No downward trend over the years was observed. The first month of life was found to have the highest mortality rate (38.7%). Pneumonia was the leading cause of death (40.6%), and occurred significantly more often in infants than in newborns (53.7% versus 20%; p-value\u00a0=\u00a00.000046). The hospital was the most commonly reported place of death in the neonatal group, whereas in infants the body was predominantly disclosed at the place of residence. Disease-related deaths were the most prevalent throughout the analyzed population. Moreover, intrapartum-related deaths were more common in the neonatal group and violent deaths occurred more frequently among infants.\n\nID: 42068524\nTitle: Community-Led Solutions to Address Black Maternal and Infant Mortality Through the TNT-PISP Model: A Qualitative Study.\nAbstract: In both the U.S. and Wisconsin, Black women and infants experience significantly higher rates of morbidity and mortality than their white counterparts. Our research team set out to explore how a community-based and culturally informed perinatal support model could address the needs of Black mothers and their families. We developed and implemented the Today Not Tomorrow Pregnancy and Infant Support Program (TNT-PISP), a community-based, culturally informed perinatal support model integrated with traditional obstetrical care. From October 2019 to August 2022, we held monthly support group sessions facilitated by Black community-based doulas, Black physicians, and community partners. Twenty-five participants engaged in topic-focused and freeform sessions to discuss mental health, breastfeeding, peripartum care, and medical racism. Data were collected through semi-structured interviews and focus groups and analyzed using the Daughtering Method and reflexive thematic analysis. Participants emphasized the importance of shared Black identity and culture in fostering connection and trust. The group's open, judgment-free environment allowed for meaningful conversations and emotional support. Participants valued the exchange of parenting knowledge and community resources. The program's flexible structure and child-friendly setting were key strengths, enabling consistent participation despite busy schedules. This study highlights the potential of community-based, culturally informed perinatal support programs to promote health equity for Black women and infants. Future research should explore such programs' long-term impacts and scalability in diverse settings. Continued efforts to integrate culturally relevant care models into traditional healthcare systems may help promote health inequities in Black communities.\n\nID: 42061094\nTitle: Post-mortem fundus photographs in sudden unexpected death in infancy: An overview of the typical findings.\nAbstract: To show post-mortem fundus photograph (PMFP) features seen in sudden unexpected death in infancy (SUDI), to detect retinal hemorrhages, which are a crucial hallmark for abusive head trauma (AHT). Single-center, retrospective study with SUDI cases included by a French SUDI referral center in the French national registry for SUDI cases between 2017 and 2025. All available PMFP, the final diagnosis and the post-mortem interval between death and PMFP were collected. Of the 78 SUDI cases recorded in Nantes, 65 underwent a fundus examination, of which 46 had PMFP available. The mean age at death was 4.5\u00a0\u00b1\u00a04.9\u00a0months, 30 children were male (65%). The main PMFP features were retinal changes resembling central retinal artery occlusion and macular and/or peripheral white radial retinal folds. The presence of a macular fold was associated with a longer post-mortem interval (presence versus absence of a macular fold: 12.2\u00a0\u00b1\u00a07.2\u00a0h [range: 4-30] versus 4.5\u00a0\u00b1\u00a01.6\u00a0h [range: 3-9], p\u00a0<\u00a00.001). Retinal hemorrhages were found in four non-abusive cases with non-specific fundus features and in two confirmed AHT cases, with AHT-suggestive features. The normal post-mortem fundus in children under two years old shows a \"central retinal artery occlusion\" pattern, followed by the appearance of macular or peripheral white radial retinal folds, that should not be mistaken for circumferential perimacular retinal folds and hemorrhagic retinoschisis cavities that have been described in AHT cases. PMFP allow detecting and documenting retinal hemorrhages, which may be indicative of infanticide.\n\nID: 42058942\nTitle: First-Year Mortality in Infants Born Moderately Preterm and Late Preterm: A National Register Study.\nAbstract: To investigate first-year mortality and predictors and causes of death in infants born moderately preterm (MP; birth at 320/7-336/7 weeks of gestation) and late preterm (LP; 340/7-366/7) compared with infants born very preterm (<320/7) and term (\u2265370/7-416 /7) and to establish mortality rates by region, hospital level, and time. Data on all infants (n = 1 546 787) born in Finland between 1991 and 2016 were collected from national registers. Of those born prematurely (5.9%), infants born MP and LP accounted for 85,9%. Early, late, and postneonatal mortality decreased with advancing gestational age. Despite overall declines, early neonatal mortality remained significantly greater in infants born MP and LP than in infants born at term. Over time, early neonatal mortality decreased only in MP and LP groups, whereas first-year mortality declined in infants born MP and LP. Predictors of death in all mortality categories in infants born MP and LP included small for gestational age, low Apgar score, and ventilator treatment. Some regional and hospital-level differences in early neonatal mortality were observed. Causes of death in infants born MP and LP resembled those of term more than infants born very preterm, with congenital anomalies being the most common, albeit not easily preventable causes of death. Infants born MP and LP had an elevated risk of early neonatal mortality compared with infants born at term. Continued reductions may be achieved by targeting preventable causes such as asphyxia and respiratory distress, while counseling-based interventions may help prevent sudden infant death syndrome and reduce late neonatal and postneonatal mortality.\n\nID: 42047799\nTitle: Molecular mechanisms of sudden unexplained death and recent updates on molecular autopsy strategies for forensic investigation.\nAbstract: Forensic investigation of sudden unexplained death (SUD) has long been a challenging issue due to its insidiousness and complex pathological basis. Comprehensive understanding of the cause of death in SUD cases could not only provide scientific guidance for judicial investigations, but also help to prevent such tragedies from recurring by identifying at-risk individuals. Recent development and application of molecular autopsy have provided crucial support for addressing this problem. In such a context, this review systematically collates the potential molecular mechanisms underlying SUD with a focus on its genetic background. In addition, the progress and challenges of existing molecular autopsy strategies were elaborated in detail, in order to guide the multidisciplinary management of SUD from the perspective of forensic geneticists.\n\nID: 42005631\nTitle: Delayed Breastfeeding Initiation and Associated Factors in Tanzania: A Cross-Sectional Study.\nAbstract: Delayed initiation of breastfeeding is associated with poor child development outcomes and increased risk of infant mortality, which remains a major public health challenge in low- and middle-income countries. Despite global and national efforts to promote optimal breastfeeding, early initiation remains suboptimal in much of Sub-Saharan Africa. This study examined the prevalence and factors associated with delayed initiation of breastfeeding in Tanzania. We analyzed secondary data from the 2022 Tanzania Demographic and Health Survey and Malaria Indicator Survey, a nationally representative cross-sectional survey. The study population comprised children under 24 months. The outcome variable was delayed breastfeeding initiation, defined as not initiating breastfeeding within 1\u2009h of life. Weighted data were analyzed using multilevel mixed-effects logistic regression to identify associated factors. A total of 4478 children were included, with a mean (\u00b1SD) age of 11.5\u2009\u00b1\u20096.9 months. The prevalence of delayed initiation was 24.4%. Child-related factors included first (aPR\u2009=\u20091.32; 95% CI: 1.13-1.55) and second birth order (aPR\u2009=\u20091.21; 95% CI: 1.06-1.39). Maternal age 35-49 years was also associated (aPR\u2009=\u20091.16; 95% CI: 1.02-1.32). Health-related factors included absence of immediate skin-to-skin contact (aPR\u2009=\u20091.85; 95% CI: 1.64-2.09), cesarean delivery (aPR\u2009=\u20092.45; 95% CI: 2.17-2.78), lack of birth assistance (aPR\u2009=\u20091.63; 95% CI: 1.16-2.28), and assistance from non-skilled provider (aPR\u2009=\u20091.42; 95% CI: 1.09-1.84). Geographically, delayed initiation was more prevalent in Zanzibar (aPR\u2009=\u20091.62; 95% CI: 1.33-1.98) and less prevalent in the Southern zone (aPR\u2009=\u20090.54; 95% CI: 0.36-0.80). Nearly one in four newborns in Tanzania experience delayed breastfeeding initiation. Delayed initiation was associated with child, maternal, health-related, and geographical factors. Strengthening skin-to-skin contact, skilled birth attendance, cesarean support, counseling for first-time and older mothers, and addressing geographical disparities may improve early initiation and support progress toward Sustainable Development Goal target 3.2.\n\nID: 41990011\nTitle: Pooled incidence and predictors of infant mortality in low- and middle-income countries using gamma shared frailty model: Insights for achieving the Sustainable Development Goals.\nAbstract: Low- and middle-income countries (LMICs) account for a large share of global infant deaths, but there is a lack of evidence on the pooled estimate of infant mortality and its predictors in LMICs. Therefore, this study aimed to assess the pooled incidence of infant mortality and its associated factors in LMICs. We used clustered data extracted from the recent Demographic and Health Surveys (DHS 2018-DHS 2024) of all LMICs. A total of 1,404,826weighted numbers of recent live births were included in the study. A lognormal shared gamma frailty model was employed. We used the Akaike information criterion (AIC), Bayesian information criterion (BIC), and log-likelihood values for model comparison. An adjusted time ratio ([Formula: see text]) with a 95% confidence interval (CI) in the final model was used to select variables that had a significant association with time to infant death. The data were analyzed via R software version 4.3.1. A total of 1,404,826 live births were included in the final analysis. By the end of the follow-up period, 72,569 infants (5.17%, 95% CI: 5.13-5.21) had died before their first birthday. The pooled estimate of the IMR in LMICs was 39 per 1000 live births (95% CI: 32.68-44.95). Maternal education, family size\u2009\u2265\u20095, being a multiparous mother, being delivered at health facilities, being a female infant, immediate initiation of breast feeding, living in Europe & Central Asia, and living in West & East Asia were significantly associated with a lower risk of infant death. Conversely, maternal age 25-34, maternal age 35-49, unimproved toilet facilities, poor and middle wealth indices, maternal age at birth \u226419, birth interval of <18 and 18-23 months, multiple births, 2nd birth order, small birth size, low and medium Human Development Index (HDI), low and medium literacy rate, low-income and lower-middle income countries, rural residence, living in West Africa, South & Central Africa, and South Asia were significantly associated with a higher risk of infant mortality. The infant mortality rate (IMR) in LMICs remains high compared with that in WHO targets and shows significant regional variation. West Africa and South Asia had the highest pooled estimate of infant deaths. Variables such as maternal age, education, wealth index, age at first birth, parity, family size, child sex, birth interval, multiple pregnancy, birth order number, perceived child size at birth, place of delivery, residence, country's literacy rate, income group, and HDI value were identified as significant predictors of time to infant death. Therefore, public health interventions that enhance health facility delivery, optimal birth spacing, maternal education, and immediate breastfeeding are crucial to reduce the incidence of infant mortality in LMICs.\n\nID: 41960368\nTitle: Cellular Functional Analyses of ARX Variants Reveal New Insights Into Genotype-Phenotype Correlations in Neurodevelopmental Disorders Among Male and Female Patients.\nAbstract: Neurodevelopmental disorders (NDDs) encompass a wide range of conditions often linked to genetic causes, with mutations in the X-linked ARX gene representing a recurrent contributor. ARX encodes a transcription factor critical for GABAergic neuron development and functioning, regulating the expression of key neurodevelopmental target genes. Variants in ARX result in a wide clinical spectrum, ranging from asymptomatic female carriers to severe developmental syndromes in both sexes. This study investigates the functional impact of 16 ARX variants, including known pathogenic, likely pathogenic, and novel de novo variants, some associated with atypical presentations such as sudden infant death. Using transient expression in N2a neuroblastoma cells, we employed a comprehensive functional approach-including luciferase reporter assays, Western blotting, immunofluorescence, and RT-qPCR-to assess protein expression levels, subcellular localization, their interaction with known corepressors (TLE1 and CtBP1), and their transcriptional activity on selected ARX-known targets. Our results demonstrate that all tested variants disrupt normal ARX transcriptional function, with several also altering protein localization or expression. Remarkably, a subset of variants exhibited dominant-negative effects, offering a compelling explanation for unexpectedly severe phenotypes in female patients, likely exacerbated by skewed X-inactivation and other modifying factors. By integrating experimental data with a literature-based review of published ARX variants, we provide refined genotype-phenotype correlations, highlighting the importance of mutation type, positional context within key ARX functional domains, and patient sex. Altogether, this study advances our understanding of the molecular mechanisms driving ARX-related NDDs, emphasizing the importance of functional testing for accurate variant interpretation and paving the way toward informed genetic counseling and potential therapeutic development.\n\nID: 41938522\nTitle: CYP450 Constraints in Infants: A Multidomain Convergence Framework for Investigating Mechanistic Vulnerability.\nAbstract: Cytochrome P450 (CYP450) enzymes are the primary hepatic Phase I oxidative biotransformation system for many drugs and xenobiotics; variability in CYP capacity is therefore a key determinant of metabolic reserve. Reserve varies with developmental ontogeny, genotype, and acquired suppression (e.g., cytokine-mediated phenoconversion). Early infancy represents a developmental window in which clearance capacity and redox/energetic buffering may be comparatively constrained. We introduce a hypothesis-generating Three-Axis Convergence Framework (TCF) modeling interacting effects of (i) developmental/genetic reserve limits, (ii) immune-cytokine modulation of metabolism, and (iii) exposure/disposition context, and translate this synthesis into a structured postmortem interpretive tool integrated into the primary medicolegal autopsy, using an enhanced analytic panel applied selectively based on case context and specimen validity/QC to support mechanistic characterization of infant deaths remaining unexplained (often SUID/SIDS). A structured narrative synthesis was conducted spanning developmental pharmacology, pharmacogenetics, immunology, redox biology, neuropathology, and toxicology. Routine medicolegal postmortem practices used in SUID investigations were reviewed to identify measurement gaps that may limit mechanistic resolution in unexplained cases. The synthesis was formalized into five analytic domains: CYP450 capacity, immune/cytokine load, redox balance/energetics, neurochemical integrity, and xenobiotic/metal burden. The Metabolic Vulnerability Index (MVI) operationalizes the TCF as a five-domain ordinal scoring system (0-15). Domain 1 is anchored by hepatic CYP protein abundance (a more postmortem-stable proxy than CYP activity assays, which are generally constrained by rapid functional decay and QC limitations), normalized to adult reference and interpreted against age-matched developmental expectations. Domain-combination lookup tables route users to 14 mechanistically defined archetypes and specify modifier/exposure-context documentation. Appendices define an operational postmortem workflow, specimen validity rules, analytic QC constraints, detection limits, and a worked example. A Cytokine-Metabolic Suppression Profile (CMSP) is presented as an interpretive coherence summary and does not modify MVI scoring or certification. The MVI provides a structured framework for describing multidomain physiologic constraints in unexplained infant deaths alongside standard forensic practice. In this way, the TCF, MVI, and CMSP together offer a disciplined response to long-standing mechanistic uncertainty in early life-by enabling systematic measurement, coherent interpretation, and transparent identification of evidence gaps, rather than asserting new causes.\n\nID: 41926549\nTitle: Research at the Paris Foundling Hospital, Part 1: Until and during the Revolution.\nAbstract: The Paris Foundling Hospital was a breeding ground for neonatal medicine, but little is known about its research. During the century preceding the Revolution, admission of newborns rose dramatically, making this institution the largest infant hospital in the world. A total of 3,162 infants were admitted in 1742, of whom 40% died in the hospice and another 20% with the nurses. During the Revolution (1789-1804), monasteries were transformed into jails or hospitals, and the foundling hospital became a teaching institute. Students flocked to the capital, and those believed to qualify for hospital positions were selected through competing publications. A major research focus was trials of artificial nutrition, motivated by the fear of transmitting venereal disease to wet nurses via breastfeeding. Cows and goats were held on the premises, but milk was kept without refrigeration. A research branch of the foundling hospital was in Vaugirard, directed by Fran\u00e7ois Doublet. In 1781, he treated syphilitic newborns by wet-nursing them from syphilitic nurses treated with mercury. Another approach requiring considerable logistics was sending thousands of infants to the countryside for wet-nursing. In 1769, Joseph Raulin analyzed the mortality at the hospice and found that thrush, diarrhea, marasmus, suffocation, and inflammation were the major causes of death. Foundling hospital surgeon Jean-Abraham Auvity published prize-winning treatises on thrush and sclerema in 1786. He related skin hardening (sclerema) to postnatal hypothermia and developed warming techniques for premature infants. During the Revolution and Terror, meaningful research was conducted at the foundling hospital but failed to lower mortality.\n\nID: 41911268\nTitle: Maternal smoking behaviour during pregnancy and the association of Sudden Unexpected Infant Death (SUID): A retrospective cohort study of births in the United States from 2017-2021.\nAbstract: Maternal smoking during pregnancy is a significant risk factor for sudden unexpected infant death (SUID). However, the impact of variations in smoking behaviours, including timing, intensity, and cessation, remains understudied. This study examines the association between maternal smoking and SUID, incorporating detailed categorizations of smoking behaviours. We conducted a population-based, retrospective cohort study of live births in the United States from 2017 to 2021 using the Centre for Disease Control Linked Birth-Infant Death files. Maternal smoking was categorized as non-smoking, pre-pregnancy smoking only, trimester-specific smoking, continuous or discontinuous smoking, and cessation before the third trimester, with stratification by smoking intensity. SUID was defined using ICD-10 codes. Multivariable logistic regression was used to estimate unadjusted (OR) and adjusted odds ratios (aOR) for SUID. Sensitivity analyses examined mediation by gestational age and infant birth weight. Heavy continuous smokers had the highest aOR for SUID (372.8 per 100,000 births; aOR 2.81, 95% CI 2.67-2.94), followed by light continuous smokers (395.6 per 100,000 births; aOR 2.47, 95% CI 2.19-2.78) and discontinuous heavy smokers (292.5 per 100,000 births; aOR 2.29, 95% CI 1.72-3.00) compared with non-smokers. Pre-pregnancy-only smokers had the lowest odds of SUID among all smoking categories (light: 188.2 per 100,000 births; aOR 1.77, 95% CI 1.48-2.10; heavy: 152.8 per 100,000 births; aOR 1.61, 95% CI 1.44-1.78). In the sensitivity analysis, the natural indirect effect (NIE) of continuous smoking throughout pregnancy on SUID through gestational age and infant birth weight were insignificant (gestational age: \u03b2\u2009=\u20091.01, 95% CI 0.99-1.03, p\u2009=\u20090.28, infant birth weight: \u03b2\u2009=\u20091.04, 95% CI 0.99-1.08, p\u2009=\u20090.10). Maternal smoking significantly influences SUID, with earlier cessation exhibiting weaker associations. These findings emphasize the importance of early smoking cessation interventions to improve SUID outcomes.\n\nID: 41911090\nTitle: Sudden Unexpected Postnatal Collapse in the Netherlands: A National Registry Study.\nAbstract: Sudden unexpected postnatal collapse (SUPC) is a rare and potentially life-threatening event with variable reported incidences, mostly derived from in-hospital data. This study investigated the incidence, aetiology, and circumstances of SUPC in the Netherlands and assessed differences between in-hospital and home settings. Data concerning SUPC cases were obtained through a web-based registry managed by the Dutch Paediatric Surveillance Unit from April 2019 to April 2022. SUPC was defined as a collapse within 24 h of birth requiring resuscitation with at least positive pressure ventilation in infants born at \u226535 weeks of gestation and with a 5-min Apgar score \u22658. Of 94 registered SUPC cases, 60 met inclusion criteria: 52 cases occurred in hospital and 8 at home. The annual incidence ranged between 7 and 17 per 100,000 live births, with an average of 11 per 100,000. Median time to collapse was 64 min, with over two-thirds occurring within 2 h of birth. Collapses occurring at home occurred significantly later than those in hospital (165 min vs. 60 min; p < 0.05) and were associated with substantially higher mortality rates (37.5% vs. 6%; p < 0.05). Approximately half of all SUPC cases involved possible or definite airway obstruction, which - compared with other aetiologies - was more often related to preventable factors like reduced maternal vigilance and covering of the infant's nose and mouth. SUPC occurs in hospitals and at home, with later onset and higher mortality outside the hospital. Greater awareness and prevention are needed in both settings.\n\nID: 41851818\nTitle: Differences in heart DNA methylation between sudden infant death syndrome and other sudden deaths.\nAbstract: Sudden Infant Death Syndrome (SIDS) remains a leading cause of infant mortality worldwide, yet its underlying mechanisms are largely unknown. SIDS etiology is complex and involves the interplay between a vulnerable infant, a critical developmental period, and external stressors. Cardiac function, including cardiorespiratory autonomic control, is considered a major contributor to SIDS. Emerging evidence suggests that epigenetic modifications of heart tissue, particularly DNA methylation (DNAm), may contribute to SIDS risk. We conducted an epigenome-wide association study (EWAS) to determine if DNA methylation patterns of post-mortem heart tissue differ between SIDS cases and non-SIDS controls, and to evaluate the role of DNAm in timing of SIDS events. Using a case-control study design, we generated DNA methylation data using Illumina EPIC Methylation V2 arrays and performed single site EWAS, differentially methylated region (DMR), and epigenome network cluster analyses to assess differential DNA methylation between SIDS cases and non-SIDS controls. Post-mortem heart tissues from 324 infants (202 SIDS cases) were obtained from the Chicago Infant Mortality Study (CIMS) and the NIH NeuroBioBank (NBB). Inclusion criteria required SIDS cases to meet standardized SIDS definitions, as determined from a through case investigation (i.e., autopsy, death scene examination, and clinical history). Seven CpG sites were differentially methylated between SIDS cases and non-SIDS control (adjusted (adj.) p\u2009<\u20090.05). Two were located within DTNB (cg1703363; adj. p\u2009=\u20090.02) and NDUFS8 (cg12070987; adj. p\u2009=\u20090.02). There were two differentially methylated regions overlapping the KRTCAP3 and RUNX3 genes. Of the top ten most significant CpG-SIDS diagnosis interactions, two of them were located within mitochondrial genes, ACSL1 and AK2. This study identified differentially methylated CpG sites and regions from heart tissue in SIDS cases versus controls, notably in DTNB, NDUFS8, KRTCAP3, and RUNX3. Our findings highlight pathways enriched for mitochondrial function, immune cell regulation, and cardiac dysfunction, which indicate the heterogenous nature of SIDS and supports the need for larger multi-tissue collaborative studies to identify SIDS subtypes, underlying pathologies, and determine the causal nature of such findings.\n\nID: 41845357\nTitle: Abortion policy, political control, and maternal and infant mortality in the United States: a cross-sectional ecological study.\nAbstract: BACKGROUND: Maternal and infant mortality in the U.S. remain the highest among high-income nations, with disparities worsening after Dobbs v. Jackson Women\u2019s Health Organization. This study examined how abortion bans and partisan political control are associated with maternal and infant mortality, while accounting for sociodemographic, economic, and healthcare factors. METHODS: We conducted a cross-sectional ecological study of all 50 U.S. states, linking maternal mortality ratios (MMR) and infant mortality rates (IMR) with abortion policy classifications (total ban, ban at \u2264\u200918 weeks, ban after 18 weeks, no gestational ban) and partisan control of governors, legislatures, and senates. Multivariable regressions adjusted for sociodemographic, economic, and healthcare variables. RESULTS: Unadjusted analyses showed MMR and IMR were higher on average in Republican-led states (27 vs. 20 per 100,000; 6.3 vs. 5.0 per 1,000; all p\u2009<\u20090.01), with political control accounting for up to one-quarter of the variance (R\u00b2=0.21\u20130.25). In adjusted models, total abortion bans were correlated with higher MMR (\u03b2\u2009=\u20095.28, p\u2009=\u20090.0315, R\u00b2=0.81) and IMR (\u03b2\u2009=\u20091.15, p\u2009=\u20090.0014, R\u00b2=0.86). Higher mortality correlated with greater fertility and larger Black population shares; protective factors included higher income, state investment, education, life expectancy, Hispanic population, and healthcare access. These patterns clustered by party control. CONCLUSIONS: In this ecological analysis, abortion bans and Republican political control were correlated with higher maternal and infant mortality at the state level. While individual-level causality cannot be inferred, addressing structural disparities may help reduce preventable deaths. Maternal and infant deaths remain higher in the United States than in other wealthy countries. These problems have become worse since the Dobbs v. Jackson Women\u2019s Health Organization decision, which allowed many states to ban or restrict abortion. Our study looked at whether abortion laws and political control in each state are related to the number of women who die during or shortly after pregnancy (maternal mortality) and the number of infants who die before their first birthday (infant mortality).We studied all 50 states uosing publicly available data. We compared maternal and infant death rates with state abortion policies (from total bans to no gestational bans) and with whether Republicans or Democrats controlled the governor\u2019s office and state legislatures. We also considered other important factors such as income, education, access to healthcare, and racial/ethnic makeup of the population.We found that states with abortion bans and Republican political control had higher maternal and infant death rates than states without bans and with Democratic control. For example, maternal mortality was about one-third higher in Republican-led states. Higher fertility rates and larger Black populations were linked with more deaths, while protective factors included higher income, greater state investment, more education, longer life expectancy, and larger Hispanic populations.Our findings show that restrictive abortion policies and political control are linked with worse outcomes for mothers and infants. Although this type of study cannot prove direct cause, it highlights the need to address underlying inequalities to save lives.\n\nID: 42479854\nTitle: Early-Life Intervention with Bifidobacterium longum subsp. infantis CCFM1269 Alleviates Atopic Dermatitis in Mice via the Indole-3-Lactic Acid-AHR Signaling Pathway.\nAbstract: Atopic dermatitis (AD) is a prevalent early childhood inflammatory skin disease frequently linked to gut dysbiosis. While Bifidobacterium longum subsp. infantis is a pioneer infant gut colonizer driving immune maturation, its role in AD prevention remains unclear. Here, we investigated early life intervention with B. longum subsp. infantis CCFM1269 using a 2,4-dinitrofluorobenzene (DNFB)-induced murine AD model. Oral administration of CCFM1269 significantly ameliorated AD symptoms, reducing skin/ear thickness, dermatitis scores, and serum IgE. Mechanistically, CCFM1269 modulated the systemic Th1/Th2 balance by downregulating TSLP, IL-4, and IL-13, while upregulating IFN-\u03b3. Notably, CCFM1269 produced indole-3-lactic acid (ILA). Via the gut-skin axis, ILA activated the aryl hydrocarbon receptor (AHR) and its target CYP1A1 in skin tissues, strengthening the epidermal barrier. Additionally, AD mitigation was associated with gut microbiota reshaping. Ultimately, CCFM1269 alleviates AD primarily through the ILA- AHR signaling pathway, highlighting its potential as a functional food ingredient for early life AD prevention.\n\nID: 42479655\nTitle: Complementary feeding in Mexico by 2026: a review and recommendations from the Academia Mexicana de Pediatr\u00eda.\nAbstract: The present document aims to present a reflection derived from a narrative review on the evolution of complementary feeding (CF) recommendations worldwide and their application in Mexico. Based on the analysis of international guidelines and consensus statements, such as those published by European Society for Pediatric Gastroenterology, Hepatology and Nutrition, Latin American Society of Pediatric Gastroenterology, Hepatology and Nutrition, and the World Health Organization, members of the Mexican Academy of Pediatrics review the main points of convergence and controversy related to the initiation, progression, and characteristics of CF during the first two years of life. The document highlights that this period is critical for growth, neurological development, immune maturation, and the establishment of healthy eating habits in the long term. Likewise, it emphasizes the relevance of the first 1000 days of life and the need to promote breastfeeding, dietary diversity, and the timely introduction of foods rich in essential nutrients. The review also addresses current topics such as the early introduction of allergenic foods, the role of different food textures, the prevention of obesity and allergies, as well as the importance of avoiding sugar-sweetened beverages, ultra-processed foods, and restrictive diets without specialized supervision. From the Mexican perspective, it is recognized that international recommendations must be contextualized according to the epidemiological, cultural, and social realities of the country. Finally, the Academia Mexicana de Pediatr\u00eda proposes practical recommendations directed at healthcare professionals to promote responsive, safe, and evidence-based CF that contributes to the overall well-being of Mexican infants. El presente documento tiene como objetivo manifestar algunas reflexiones derivadas de una revisi\u00f3n narrativa sobre la evoluci\u00f3n de las recomendaciones de la alimentaci\u00f3n complementaria (AC) en el mundo y su pr\u00e1ctica en M\u00e9xico. A partir del an\u00e1lisis de consensos y gu\u00edas internacionales, como las publicadas por la Sociedad Europea de Gastroenterolog\u00eda, Hepatolog\u00eda y Nutrici\u00f3n Pedi\u00e1trica, la Sociedad Latinoamericana de Gastroenterolog\u00eda, Hepatolog\u00eda y Nutrici\u00f3n Pedi\u00e1trica y la Organizaci\u00f3n Mundial de la Salud, miembros de la Academia Mexicana de Pediatr\u00eda revisan los principales puntos de convergencia y controversia relacionados con el inicio, progresi\u00f3n y caracter\u00edsticas de la AC durante los primeros dos a\u00f1os de vida. El documento destaca que este periodo es cr\u00edtico para el crecimiento, desarrollo neurol\u00f3gico, maduraci\u00f3n inmunitaria y establecimiento de h\u00e1bitos alimentarios saludables a largo plazo. Asimismo, se enfatiza la relevancia de los primeros 1,000 d\u00edas de vida y la necesidad de promover la lactancia materna, la diversidad alimentaria y la introducci\u00f3n oportuna de alimentos ricos en nutrimentos esenciales. La revisi\u00f3n tambi\u00e9n aborda temas actuales como la introducci\u00f3n temprana de alimentos alerg\u00e9nicos, el papel de las diferentes texturas, la prevenci\u00f3n de obesidad y alergias, as\u00ed como la importancia de evitar bebidas azucaradas, ultraprocesados y dietas restrictivas sin supervisi\u00f3n especializada. Desde la perspectiva mexicana, se reconoce que las recomendaciones internacionales deben contextualizarse seg\u00fan las realidades epidemiol\u00f3gicas, culturales y sociales del pa\u00eds. Finalmente, la Academia Mexicana de Pediatr\u00eda propone recomendaciones pr\u00e1cticas dirigidas a profesionales de la salud, con el fin de favorecer una AC perceptiva, segura y basada en evidencia cient\u00edfica, que contribuya al bienestar integral de las y los lactantes mexicanos.\n\nID: 42474821\nTitle: Can slow and (un)steady still win the race? A narrative review of developmental gait characteristics and clinical implications in children born preterm.\nAbstract: Independent walking is more than a developmental milestone, as it reflects the integration of neuromuscular maturation, postural control, and sensorimotor coordination. In children born preterm, both the timing and the characteristics of independent walking may differ from those observed in term-born peers. This narrative review synthesizes current evidence on independent walking acquisition and gait features in preterm-born children throughout different stages of life, from toddler to school age, and discusses the clinical implications of quantitative gait assessment, with a focus on innovative wearable technologies, during neurodevelopmental follow-up. Preterm birth is consistently associated with a 1-2-month delay in independent walking onset compared with term-born peers, even after correction for gestational age (GA), with greater delays reported in infants born at lower GA or with very low birth weight (BW). Beyond milestone attainment, both qualitative and quantitative studies describe less mature gait patterns during early walking and the preschool years, including shorter step length, wider base of support, prolonged double-support phase, increased temporal variability, and reduced gait complexity. These characteristics likely reflect compensatory strategies related to immature postural control and sensorimotor organization. Although many spatiotemporal parameters improve with age and walking experience, subtle differences may persist into school age, particularly under more demanding conditions such as dual-task walking. However, currently available studies on preterm gait are quite heterogeneous in terms of GA, BW, and/or individual walking experience of included individuals and gait analysis methods employed. Furthermore, evidence regarding gait characteristics in preschool and school-aged preterm children is still relatively scarce, thus hampering a deeper understanding of preterm-born children's gait development after the toddler stage. \u00a0Instrumented gait analysis systems and wearable technologies, including inertial measurement units, enable objective and ecologically valid assessment of gait performance. Quantitative gait parameters have shown associations with standardised gross motor scores and may provide additional information beyond milestone history alone. Incorporating structured quantitative gait assessment into longitudinal follow-up programmes could support more detailed monitoring of motor development and inform individualised rehabilitation planning in children born preterm. \u2022\u00a0Children born preterm generally achieve independent walking later than term-born peers and may show immature gait features, particularly during the first years of life. \u2022\u00a0Most available evidence is heterogeneous and focuses mainly on walking onset or early gait, with limited data extending into preschool and school age. \u2022\u00a0This review integrates evidence on gait development from the fi rst independent steps to school age, identifying persistent abnormalities mainly in children born at lower gestational ages, with lower birth weight, or under demanding walking conditions. \u2022\u00a0It highlights the potential role of quantitative gait analysis and wearable inertial sensors as complementary tools for longitudinal neurodevelopmental follow-up and individualized rehabilitation planning.\n\nID: 42472855\nTitle: Umbilical cord blood biomarkers of neuronal injury in sleep-disordered breathing during pregnancy.\nAbstract: Sleep-disordered breathing (SDB) during pregnancy may compromise fetal development and brain maturation. Ubiquitin C-terminal hydrolase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP) are biomarkers of neuronal injury and cellular stress and may provide insight into fetal vulnerability in this context. UCH-L1 and GFAP concentrations were measured in umbilical cord blood from 85 neonates born to women who underwent hospital-based polysomnography during the third trimester. The apnea-hypopnea index (AHI, and rapid eye movement (REM)-AHI)) and mean nocturnal oxygen saturation (mSaO2) were assessed. SDB phenotypes (OSA n\u2009=\u200914; REM-OSA n\u2009=\u200925; and mSaO\u2082 \u226495% n\u2009=\u200931) showed no significant differences in UCH-L1 or GFAP compared with controls. However, UCH-L1 levels were higher in neonates exposed to shorter apnea-hypopnea (AH) events, and both maternal AH length and mSaO2 were negatively correlated with UCH-L1 concentrations. Overall, maternal SDB was not broadly associated with differences in UCH-L1 and GFAP levels. Nevertheless, elevated neonatal UCH-L1 linked to non-traditional metrics, such as AH length and mSaO\u2082, suggests fetal cellular stress and highlights its potential as an early biomarker of neurodevelopment risk.\n\nID: 42457069\nTitle: Maternal pathways linking sociocognitive resources and immune balance to infant neurodevelopment: from cytokines to education.\nAbstract: The COVID-19 pandemic renewed interest in prenatal immune exposures and offspring neurodevelopment. While maternal immune activation (MIA) is associated with neurodevelopmental disorders (NDD), emerging evidence suggests that immune balance-particularly within the IL-6/IL-10 axis-may be more informative than absolute inflammatory levels. In the COGESTCOV-19 cohort, 95 children (50 prenatally exposed to maternal SARS-CoV-2 infection; 45 controls) were reassessed at 26\u00a0months using the Bayley-III (cognitive, language, and motor domains). Group comparisons (ANOVA/ANCOVA) and linear and nonlinear regressions (GAMs) examined associations between Bayley-III scores and the maternal baseline IL-6/IL-10 ratio, focusing on samples obtained within 0-4\u00a0weeks post-infection/vaccination; sensitivity analyses extended this window to 9\u00a0weeks. No overall differences in Bayley-III outcomes were observed between exposed and control groups after covariate adjustment. However, time-sensitive nonlinear associations emerged. Among non-vaccinated mothers infected during pregnancy and sampled within 0-4\u00a0weeks post-infection, higher IL-6/IL-10 ratios were associated with lower model-estimated offspring expressive-language and fine-motor scores in specific analytical subsets. Vaccination was associated with higher IL-10 levels in controls, not cases, and longer post-vaccination intervals corresponded to declining IL-10 in controls. Independently, higher maternal education predicted better communication outcomes, while advanced maternal age showed nonlinear associations with poorer fine motor performance. Variation in maternal immune balance during infection may be associated with subtle, domain-specific differences in early neurodevelopment. These exploratory findings do not establish causal immune pathways, a clinical IL-6/IL-10 threshold, or a protective effect of vaccination and require independent replication.\n\nID: 42455951\nTitle: Scent of a father: Paternal body odors boost interbrain synchrony.\nAbstract: Olfactory cues are ancient signals and mammalian young utilize maternal body odors (BO) to form a bond to their habitat in the absence of the mother, strengthen associative learning, and grow a social brain. Whether infants respond to their father's BO and how paternal BO impact their brain maturation is still unknown. Utilizing ecologically-valid paradigms with dual-electroencephalography recordings, we measured infant-father and infant-stranger interbrain synchrony during naturalistic interactions and assessed the effects of paternal BO. Infants show greater interbrain synchrony with father compared to a stranger male. Paternal BO increase infant-stranger interbrain synchrony and enhance the father-typical positive arousal, providing evidence that infants process their father's odor and can invoke his presence in his absence. Fathers contribute to brain maturation by enhancing cross-hemisphere connectivity in alpha rhythm that sustains attention regulation during stimulating social interactions. Paternal olfactory cues can invoke infants' associative learning and may push the development of more complex neural and behavioral competencies.\n\nID: 42451508\nTitle: Nonlinear Measures Applied to Spontaneous Infant Movement Analysis: A Scoping Review.\nAbstract: Spontaneous movement analysis provides valuable information about the maturation of the central nervous system and the emergence of motor control strategies in very young babies. Nonlinear measures capture dynamic aspects of movement that cannot be represented by linear methods. However, their implementation in clinical practice faces challenges, including the lack of standardized protocols and accessible tools for routine use. This scoping review aimed to map and characterize the nonlinear measures used to analyze spontaneous infant movement, including assessment context, instruments, data collection protocols, and main variables. The review followed JBI methodology and PRISMA-ScR guidelines. Searches were conducted in PubMed\u00ae, Web of Science\u2122, IEEE Xplore\u00ae, ScienceDirect\u00ae, and Google Scholar for studies published from 1 January 2005 to 31 December 2025. Of 1166 records identified, 18 met the inclusion criteria. The nonlinear measures were grouped into five main methodological families: entropy-based measures (n = 10), state-space and dynamical systems measures (n = 4), recurrence-based analysis (n = 3), symbolic and discrete-state approaches (n = 3), and variance and frequency-based nonlinear descriptors (n = 1). Studies were conducted in laboratory settings (n = 6) and in hospital and/or home environments (n = 10). Two studies did not clearly specify the assessment context. Kinematic assessment was mainly performed using video-based systems (n = 7), accelerometers (n = 4), and wearable sensors (n = 2), with most studies focusing on the upper and lower limbs. Several investigations extended beyond single-joint analyses to examine inter-limb relationships and whole-body configurations, capturing spatial coordination patterns across multiple body segments. Kinetic assessment was conducted using pressure mats (n = 4) and force platforms (n = 1), with the center of pressure displacement as the primary outcome. Future research should prioritise methodological harmonisation and theoretical clarity. Consensus is needed regarding minimal data requirements, parameter selection, and reporting standards for commonly used nonlinear measures. Studies should also move beyond single-metric approaches and adopt multivariate frameworks that integrate complementary nonlinear metrics. The absence of standardised acquisition and analytical protocols currently limits cross-study comparability and hinders the clinical translation of nonlinear movement metrics as objective tools for early neurodevelopmental assessment.\n\nID: 42451151\nTitle: Associations Between Carotenoid Status, Visual Outcomes and Cognitive Metrics in Children: A Scoping Review.\nAbstract: Carotenoid components have a role in maintaining eye and brain development and function in children. This scoping review collates the current knowledge about the benefits of carotenoids in improving visual and cognitive function outcomes in children. This review includes observational and interventional published studies to date (January 2026) through a literature search on PubMed, Web of Science, Embase, Mendeley, and Google Scholar database platforms. We have described and measured carotenoid status in diet, serum, skin, and human milk in relation to eye and cognitive development and function in children. Human body carotenoids, \u03b1-carotene, \u03b2-carotene, lycopene, cryptoxanthin, lutein, and zeaxanthin, have been detected in significant amounts in the brain, whereas the xanthophylls lutein, zeaxanthin, and meso-zeaxanthin, are found in the eyes. Lutein, zeaxanthin, and retinoids in the ocular tissue are responsible for visual function and have been associated with visual neurocognitive skills in children. In addition, lutein, zeaxanthin, and \u03b2-carotene have been associated with cognitive function tasks in infants and children. This review shows emerging evidence on the benefits of carotenoids in children, primarily from cross-sectional studies and longitudinal cohort studies. We found a paucity of carotenoid intervention and controlled trials for direct carotenoid exposure and its relative effect on neurocognitive function and visual milestone development during early life. Additionally, further long-term studies are required to confirm carotenoid exposure in early life and its benefits to eye health and cognitive skills outcomes in later life.\n\nID: 42451055\nTitle: Meconium Microbiome Maturation Patterns Linked to Postnatal Growth Failure in Neonates.\nAbstract: Background/Objectives: This study investigated whether meconium microbial profiles differed according to postnatal growth failure (PGF) and whether gestational age (GA)-related microbial maturation patterns appeared to vary according to subsequent growth status. Methods: Meconium samples were collected from 310 neonates born at 22-40 weeks of gestation, and 16S rRNA sequencing was conducted. After excluding small-for-gestational-age infants, the analyses included 151 samples from PGF+ infants and 131 samples from PGF- infants. Microbial composition, alpha and beta diversity were compared according to PGF status. Distance-based redundancy analyses (dbRDA) were conducted to evaluate the independent association between PGF and microbiome composition. Results: The core meconium microbiome differed between groups. PGF+ infants showed a predominance of Proteobacteria (36.60% vs. 27.96%), whereas PGF- infants had relatively higher abundances of Firmicutes (35.47% vs. 30.64%) and Bacteroidetes (28.96% vs. 26.19%) than PGF+ infants. GA-related microbial maturation patterns also differed between groups. At the genus level, the PGF- group showed significant positive correlations with GA for Faecalibacterium, Sutterella, Dialister, Megamonas, Escherichia/Shigella, and Roseburia after false discovery rate correction, whereas no genus-level correlation remained significant in the PGF+ group. Alpha diversity did not differ significantly between groups, whereas beta diversity differed modestly (R2 = 0.0087, p = 0.042). After adjustment for GA and birth weight, the PGF effect remained significant in the Bray-Curtis-based dbRDA model, whereas it was not significant in the Jaccard-based model. Conclusions: PGF was associated with abundance-based shifts within shared meconium taxa, suggesting subtle differences in early microbial developmental patterns among infants who later developed PGF.\n\nID: 42448743\nTitle: Radiofrequency electrical conductivity reveals a distinct dimension of early human brain development.\nAbstract: Quantitative MRI has characterised early human brain development primarily through measures of water mobility, leaving other biophysical properties of maturing tissue unexplored. Here we show that radiofrequency electrical conductivity, reflecting ionic composition, membrane density and extracellular geometry in addition to water content, can be extracted retrospectively and at scale from the phase of conventional MRI acquisitions, revealing a distinct dimension of early brain tissue maturation and state. Applying electrical property tomography to 888 neonatal MRI sessions (784 subjects, 26-45 weeks post-menstrual age) alongside infant and childhood data, we find that whole-brain conductivity declines steeply during the perinatal period and remains independently associated with age after adjustment for mean diffusivity and ventricular volume, confirming that it represents a distinct developmental signal that is not reducible to tissue water content alone. Preterm birth was associated with elevated conductivity at term-equivalent age, particularly in deep grey matter. In neonates with hypoxic-ischaemic encephalopathy (n\u2009=\u200925), conductivity was elevated while mean diffusivity was reduced within the same tissue compartments, a dissociation indicating that these measures capture mechanistically distinct aspects of the tissue response to injury. These findings establish radiofrequency electrical properties as a new biophysical window on perinatal brain maturation and its perturbation by injury, extending quantitative MRI beyond measures of water mobility.\n\nID: 42446880\nTitle: Health and Socioeconomic Factors in School Readiness and Achievement Among Children Born Very Preterm.\nAbstract: Preterm birth is a leading cause of atypical brain development and cognitive impairment; however, there are sparse data on its association with statutory educational assessments. To evaluate school readiness at age 5 years and educational attainment at age 6 to 7 years in children born very preterm and to identify the early-life, neonatal, and socioeconomic factors associated with attainment. This retrospective cohort study included all infants born before gestational age (GA) 32 weeks in England who received care in a neonatal unit and survived to discharge. A linkage between the National Neonatal Research Database and the National Pupil Database was created to integrate neonatal clinical data with educational outcomes. The data analysis was performed between October 1, 2024, and October 31, 2025. Gestational age and area-level socioeconomic deprivation. The main outcome was school readiness at age 5 years (as measured by the Early Years Foundation Stage Profile [EYFSP]) and attainment in reading, writing, mathematics, and science at age 6 to 7 years. For each outcome, prevalence of not meeting the expected level of attainment across indices of socioeconomic deprivation and GA stratified by 23 to 26 weeks and 27 to 31 weeks were calculated. Of a total of 15\u202f857 children included (2595 born at GA 23-26 weeks [16.3%] and 13 262 born at GA 27-31 weeks [83.7%]; 8449 boys [53.3%]), 8602 (56.6%) did not meet the school readiness level at age 5 years, and 7789 (51.8%) did not meet expected attainment at age 6 to 7 years for writing, 7216 (48.1%) for math, 6354 (41.9%) for reading, and 5449 (36.0%) for science. Children born at GA 23 to 24 weeks had a higher odds of not meeting expected school readiness levels compared with those born at 31 weeks (adjusted odds ratio [AOR], 2.86 [95% CI, 2.19-3.73]). Children born in areas with the most deprivation had a higher risk of underattainment compared with those in areas with the least deprivation (EYFSP: AOR, 1.27 [95% CI, 1.11-1.45]). In adjusted models, male sex and season of birth were associated with increased risk (EYFSP: AOR, 1.96 [95% CI, 1.82-2.11] and 2.64 [95% CI, 2.41-2.90], respectively) alongside several potentially modifiable risk factors, including smoking during pregnancy (AOR range from 1.19 [95% CI, 1.08-1.31] for math to 1.31 [95% CI, 1.19-1.44] for reading); exposure to postnatal corticosteroids (EYFSP: AOR, 1.37 [95% CI, 1.13-1.65]); severe acquired neonatal brain injuries, particularly periventricular leukomalacia (EYFSP: AOR, 3.05 [95% CI, 2.04-4.58]) and hydrocephalus (EYFSP: AOR, 2.47 [95% CI, 1.48-4.13]); comorbidities of preterm birth, including necrotizing enterocolitis (EYFSP: AOR, 1.60 [95% CI, 1.20-2.14], retinopathy of prematurity (EYFSP: AOR, 1.46 [95% CI, 1.10-1.93], and bronchopulmonary dysplasia (EYFSP: AOR, 1.30 [95% CI, 1.18-1.44]); and nutrition during neonatal care (EYFSP: AOR, 1.19 [95% CI, 1.07-1.33] and 1.51 [95% CI, 1.37-1.66] for mixed feeding and exclusive formula feeding, respectively, vs breastfeeding). This cohort study of children born before GA 32 weeks found that preterm birth was associated with a substantial and persistent risk for educational underattainment across early school years, especially when combined with socioeconomic deprivation. Improving outcomes for children born preterm may require reducing social inequalities and minimizing comorbidities of preterm birth. Several modifiable early-life exposures offer practical targets for intervention, including maternal nonsmoking, appropriate corticosteroid use, and breastfeeding. Deferred school entry or targeted academic support may benefit children born very preterm, depending on birth season. These strategies may help parents, clinicians, educators, and policymakers improve long-term educational attainment for children born preterm.\n\nID: 42444072\nTitle: Sudden Unexpected Postnatal Collapse: A Retrospective Cohort Study Describing Incidence, Risk Factors and Role of Perinatal Transition.\nAbstract: This study aimed to investigate the incidence, risk factors and possible aetiology of sudden unexpected postnatal collapse (SUPC), a potentially fatal yet poorly understood event. In a retrospective cohort, patient records from 483\u2009284 infants born in Stockholm, Sweden, between 2002 and 2022 were screened for SUPC-related diagnoses. SUPC was defined as a collapse within the first 7\u2009days of life in near-term infants with good postnatal adaptation. Maternal, infant and event characteristics were collected. Urine was analysed for prostaglandin E2 (PGE2) metabolites in a subgroup of cases. We identified 149 cases of SUPC, corresponding to an incidence of 31 per 100\u2009000 live births, exceeding that of early onset sepsis caused by Group B Streptococcus. Half the SUPC cases occurred during the first four postnatal hours. The mortality was 7% and 26% suffered from neurological sequelae. The highest risk of SUPC coincided with the postnatal peak in PGE2 levels. All newborn infants were at risk of SUPC, especially within 24\u2009h of birth. SUPC was associated with early unsupervised skin-to-skin care and bed sharing. Guidelines promoting safe sleep and skin-to-skin care should be implemented to prevent SUPC and save the lives of newborn babies.\n\nID: 42437837\nTitle: Gut Microbiome in Neonatal Necrotizing Enterocolitis - A Comprehensive Review of Evidence.\nAbstract: Necrotizing enterocolitis (NEC) is one of the most catastrophic gastrointestinal emergency occurring predominantly in preterm neonates. It contributes to substantial neonatal morbidity and mortality. Disturbances in the intestinal microbiome are crucial to disease pathogenesis. In preterm infants, an immature intestinal barrier, dysregulated immune responses, and environmental exposures altogether predispose to alteration in microbial colonization and intestinal inflammation. This review was done to present the current evidence on gut microbiome alterations associated with NEC in preterm infants. A systematic search of the MEDLINE and EMBASE databases was performed using search strategy related to prematurity, intestinal microbiota, and necrotizing enterocolitis. A total of 42 studies assessing microbial composition, microbial progression, or microbial functional patterns in relation to NEC were included. Across the included studies, NEC was commonly preceded by reduced microbial diversity, delayed maturation of anerobic communities, and expansion of Proteobacteria, particularly Enterobacteriaceae family such as Klebsiella and Escherichia. Longitudinal studies further showed that these microbial changes may become evident days to weeks before clinical disease, suggesting a potential window for early risk identification. Functional analyses also showed alterations in microbial metabolic pathways, including short-chain fatty acids, tricarboxylic acid intermediates, volatile compounds, and viral signatures that may lead to epithelial injury and inflammatory signaling. Clinical and environmental factors including antibiotic exposure, mode of delivery, feeding practices, and NICU microbial ecosystem are important determinants of neonatal gut microbiome development. Thus, the current evidence supports a reproducible pattern of intestinal dysbiosis preceding NEC. Better understanding of microbiome dynamics may aid early risk stratification and support microbiome-targeted preventive strategies in vulnerable preterm populations.\n\nID: 42437582\nTitle: A longitudinal examination of gut microbiota dysbiosis and neuro-behavioral phenotypes of poly(I:C)-maternal immune activation in a preclinical model of autism and schizophrenia.\nAbstract: Maternal immune activation (MIA) induced by polyinosinic/cytidylic acid [poly(I:C)] is a widely used approach to study how gestational inflammation affects neurodevelopment. For this reason, we aimed to describe the changes in gut microbiota and neurobehavioral phenotypes across the lifespan of the MIA offspring. We administered poly(I:C) on gestational day 12 to induce MIA in pregnant C57 mice. Subsequently, we conducted behavioral phenotyping, a neuropharmacological sensitivity test, a morphological analysis of dendritic branches and spines, and a gut microbiota assessment in male offspring. Here, we performed a longitudinal analysis of gut microbiota maturation across development in poly(I:C)-MIA offspring and integrated these findings with behavioral and neuronal morphology assessments relevant to ASD and schizophrenia. Our results show that MIA treatment induces an increase in the marble burying test, which assesses repetitive and persevering behavior related to obsessive-compulsive disorder, as well as decreased social interaction, anhedonia, sensitivity to the psychotomimetic drug amphetamine, and a reduction of dendritic branches and spines in the pyramidal neurons of layers II/III of the prefrontal cortex. We also observed infant gut dysbiosis on postnatal day (PD) 30. This condition is unrelated to maternal vertical transferences and persisted until early adulthood (PD57) and adulthood (PD100). Our results show that MIA is a consistent and robust preclinical model of ASD/SCZ that allows identifying symptoms and signs of these disorders, which agrees with epidemiological human evidence. Additionally, the gut dysbiosis induced by MIA could be permanent, and since it is not induced by vertical transference, it could be supported by the brain-gut-microbiota axis effects. Additional neuroimmune and microbiological studies, such as microbiota transplantation or antibiotic interference, are necessary to better interpret the effects observed in this study.\n\nID: 42433392\nTitle: The impact of COVID-19 social isolation and reduced microbial exposure on the immune system in children: a retrospective study.\nAbstract: To assess the impact of the COVID-19 pandemic and associated containment measures on the development of the immune system in children. This retrospective study analyzed clinical data from children aged 0-13 years diagnosed with respiratory tract infections at Tianshui First People's Hospital between 2019 and 2024. The dataset included 79,703 complete blood count samples and 7,931 immunoglobulin (IgG, IgA, IgM) analysis samples. Non-parametric tests (rank-sum test) and generalized linear models (Gamma distribution with Log link function) were employed for statistical analysis to evaluate the effects of different years, age groups, genders, and diagnostic types (upper/lower respiratory tract infections) on immunological parameters. The study found that the COVID-19 pandemic had heterogeneous effects on various immune cell types. Neutrophil and monocyte counts showed an increasing trend during the pandemic, whereas lymphocyte, eosinophil, and basophil counts were suppressed-with lymphocyte reduction being particularly pronounced. The suppressive effect on basophils may be persistent. Compared with 2019, no significant changes were observed in immunoglobulin levels among children from 2020 to 2022. However, beginning in 2023, serum concentrations of immunoglobulin G and immunoglobulin M showed a marked increase. This upward trend persisted through 2024, accompanied by a concurrent rebound in lymphocyte counts. Further analysis of interaction effects among age, gender, and diagnosis revealed that the impact of the pandemic on immune development was also significantly influenced by these factors. The COVID-19 pandemic and associated public health interventions have altered children's patterns of pathogen exposure, delayed the development of adaptive immunity, and disrupted the balance between innate and adaptive immunity, thereby exerting complex and long-lasting effects on immune system maturation. These findings provide valuable data for understanding the response patterns of the children's immune system under exceptional public health events and offer guidance for formulating targeted child health policies, vaccination strategies, and clinical practices in the future.\n\nID: 42429836\nTitle: Respiratory evolution after antenatal betamethasone dose reduction in very preterm neonates: a post hoc analysis of the BETADOSE trial.\nAbstract: Antenatal corticosteroids are used to accelerate fetal lung maturation. Recent studies suggest that the current dose may be too high. In the randomized multicenter BETADOSE trial, non-inferiority of the half dose compared to full dose was not shown for surfactant administration. Children with intra-uterine growth restriction have a higher risk of poor respiratory outcomes, including bronchopulmonary dysplasia, compared to those in other indications for antenatal corticosteroids. This post hoc study aims to compare respiratory outcomes between the half-dose and the full-dose groups in very preterm neonates, overall and according to indications for antenatal corticosteroids: inflammatory or vascular context including intra-uterine growth restriction. Eligible neonates were born\u2009<\u200932\u00a0weeks among those enrolled in the BETADOSE trial. The primary outcome was the occurrence of bronchopulmonary dysplasia. Multiple analyses adjusted for indications for antenatal corticosteroids, birthweight z-score, and gestational age were used. To account for multiple comparisons, p values were adjusted using the Bonferroni correction for the primary outcome. In the overall population and in the inflammatory context subgroup, there were no significant differences in respiratory outcomes, in particular surfactant use and bronchopulmonary dysplasia. The rate of discharge home with oxygen was higher in the half-dose group in the overall population. In neonates with intra-uterine growth restriction, surfactant use (63% vs 42%, p\u2009=\u20090.02) and bronchopulmonary dysplasia (40% vs 24%, p\u2009=\u20090.04) were more frequent in the half-dose group although no statistically significant difference was observed after correction using the Bonferroni method. \u00a0The impact of reducing the dose of antenatal corticosteroids may vary according to the underlying indication for administration. No firm conclusions can be drawn from these findings, which may reflect residual confounding, particularly in the subgroup with intra-uterine growth restriction. As such, this observation should be considered exploratory and further prospective studies are needed. \u2022\u00a0Antenatal corticosteroids are used to accelerate fetal lung maturation. Recent studies question the current dose of betamethasone. The non-inferiority of the half compared to the full dose was not shown regarding the use of surfactant in the BETADOSE trial. \u2022 Few differences in in-hospital respiratory outcomes were found between the half-dose and the full-dose groups. A trend toward less favorable respiratory outcomes was observed among neonates exposed to the half dose.\n\nID: 42428450\nTitle: Isolated right ventricular apical hypoplasia with atrial fibrillation in a young female at her third trimester: a case report.\nAbstract: Pregnancy represents a significant life event for most women, inducing extensive physiological adaptations. Consequently, it poses additional risks for women with congenital heart disease (CHD), a leading cause of maternal mortality. Isolated right ventricular apical hypoplasia (IRVAH) is a poorly characterized CHD subset, with pregnancy outcomes remaining unreported. Our case of a primigravida with IRVAH underscores the need for heightened monitoring in this population. We present a 28-year-old primigravida at 28 gestational weeks referred for structural right heart failure and paroxysmal atrial fibrillation (AF) with no palpitations and dyspnea. Diagnostic evaluation revealed IRVAH on echocardiography, characterized by preserved left ventricular function, severe tricuspid regurgitation, and right ventricular dilation, alongside electrocardiography showing AF; cardiac magnetic resonance imaging (MRI) subsequently confirmed apical right ventricular hypoplasia with no associated structural anomalies. Management was guided by multidisciplinary consensus, initiating stabilization with oral metoprolol (12.5 mg per dose, twice daily) for resting heart rate control (target heart rate <110 bpm). Pregnancy prolongation strategies included weekly fetal growth scans, daily maternal oxygen saturation (SpO2)/blood pressure (BP) monitoring, and steroid coverage at 30 weeks for fetal lung maturation. Due to maternal AF recurrence despite therapy, fetal growth restriction (<10th percentile), and the need to avoid hemodynamic stress from labor, an elective cesarean delivery was scheduled at 32 weeks. A preterm infant (1,580 g, Apgar scores 9/10) was delivered via cesarean section under spinal-epidural anesthesia and transferred to the neonatal intensive care unit (NICU) for recovery. Postoperative AF in the mother was successfully controlled with increased oral metoprolol (25 mg per dose, twice daily). At the 1-, 3-, and 6-month follow-ups, maternal cardiac function remained at New York Heart Association (NYHA) class I, and no developmental delays were observed in the infant. This case demonstrates the critical value of multidisciplinary team collaboration in managing pregnancy complicated by IRVAH, underscoring the need for individualized monitoring and intervention strategies. These findings may serve as a reference for the clinical management of similar cases in the future.\n\nID: 42428086\nTitle: Nutrition, Cognition and Learning: The Role of White Matter Development and Connectivity.\nAbstract: While substantial research has examined the role of infant nutrition in early brain and cognitive development, the links between later childhood nutrition, brain development, and cognitive and academic skills remain less explored. In this work, we investigated for the first time the direct and indirect associations between nutrition intake, white matter microstructure and structural connectivity, and cognitive and academic outcomes. Using longitudinal data from typically developing children aged 2 to 14 years, we combined neuroimaging, dietary, and cognitive measures to test direct associations between nutrition and brain structure and connectivity, as well as cognitive and learning outcomes, and to assess whether brain development mediated these relationships. We found that specific nutrients, including DHA, sphingomyelin, iron, niacin, choline, and palmitoleic acid (omega-7), were associated with improved brain structure and connectivity, as well as better cognitive and learning outcomes. We also found that brain development partly mediated the association between childhood nutrition and learning outcomes. To our knowledge, this is the first study to show such a pathway in school-age children. These results add to the growing literature demonstrating the ongoing importance of nutrition beyond infancy in supporting childhood brain and cognitive development.\n\nID: 42411581\nTitle: Transient B cell lymphopenia revealed by KRECs newborn screening: Post-screening referral strategies, clinical course, and follow-up.\nAbstract: Newborn screening (NBS) for inborn errors of immunity increasingly uses T-cell receptor excision circles (TREC) and, in some programs, Kappa-deleting recombination excision circles (KREC) to detect early T- and B-cell lymphopenia. While TREC-based screening is well established, the significance and management of isolated low KREC remain unclear. To evaluate the implications of two different regional post-screening algorithms for isolated low KREC and to characterize the clinical course, immunological profile, and follow-up of term newborns with transient B-cell lymphopenia. We performed a retrospective multicenter study of term newborns with isolated low KREC identified through NBS, confirmed B-cell lymphopenia, and subsequent normalization during follow-up. KREC levels, B-cell counts, and serum immunoglobulins were assessed longitudinally by RT-PCR and flow cytometry. Eighteen newborns were enrolled. At the first evaluation (V1; mean age 13.5\u2009days), all had marked peripheral B-cell lymphopenia (CD19+\u2009\u2264\u20092%; mean 54 cells/\u03bcL), although repeat dried blood spot (DBS) testing already showed KREC values above the diagnostic cutoff in 78%. By the second visit (V2; mean age 50\u2009days), B-cell percentages and absolute counts normalized in all infants, with emerging IgA and IgM production, and normal KREC on whole blood. No infectious or immunological complications were recorded over 39.5 person-years of follow-up (mean 2.3\u2009\u00b1\u20091.7\u2009years). Isolated low KREC at birth may identify newborns with transient B-cell lymphopenia that resolves during early infancy. Repeat KREC testing on a second DBS before referral may represent a pragmatic triage step to reduce unnecessary immunological evaluations, while preserving early assessment for newborns with persistent abnormalities. Prospective studies are needed to refine post-screening strategies.\n\nID: 42406847\nTitle: Extracting host-specific developmental signatures from longitudinal microbiome data.\nAbstract: Longitudinal microbiome studies provide critical insights into microbial community dynamics and their relation to host health. Tensor decompositions offer a powerful framework for the unsupervised analysis of such data, yielding interpretable low-dimensional temporal patterns. However, existing approaches based on the CANDECOMP/PARAFAC (CP) model assume common temporal dynamics for all subjects and therefore cannot capture subject-specific trajectories. To address this limitation, we introduce a novel analytical framework based on PARAFAC2 to explicitly model subject-specific variations, such as shifts and delays in temporal patterns. Through systematic comparisons on simulated and real-world datasets-including studies of infant gut maturation and dietary interventions-we demonstrate that PARAFAC2 outperforms CP in capturing subject-specific temporal trajectories, and enables the discovery of biologically relevant patterns that are overlooked by CP. Furthermore, we introduce replicability as a robust criterion for selecting the number of model components, ensuring that the extracted patterns are replicable.\n\nID: 42405434\nTitle: The Longitudinal Role of Mother-Child Synchrony in Predicting Functional Connectivity in Early Childhood.\nAbstract: Early childhood is a sensitive period for brain development, during which sustained caregiving experiences may shape neural systems that support emotion regulation and social cognition. In a longitudinal study of N = 133 mother-child dyads, we examined whether children's attachment-related behavioral patterns at age 3 were associated with functional connectivity during the viewing of attachment-related video clips. We further tested whether mother-child behavioral synchrony observed at ages 1 and 3 predicted children's functional connectivity. Neural activity was measured using functional near-infrared spectroscopy (fNIRS), targeting the prefrontal cortex (PFC), and temporoparietal junction (TPJ). Attachment-related behaviors were assessed through a structured observational procedure and rated using the Brief Attachment Screening Questionnaire (BASQ), and mother-child synchrony was coded using the Dyadic Interaction Coding (DIC) system. Children in the BASQ-derived insecure group exhibited greater intra-hemispheric connectivity, whereas those in secure group showed stronger inter-hemispheric connectivity. Mother-child synchrony at ages 1 and 3 did not independently predict later neural connectivity. Instead, mother-child synchrony at age 3 moderated the association between synchrony at age 1 and connectivity at age 3: synchrony at age 1 predicted reduced intra-hemispheric MTG connectivity only when synchrony at age 3 was high. These findings suggest that sustained mother-child synchrony may contribute to the functional organization of neural systems supporting attachment-related processing.\n\nID: 42404160\nTitle: Association between maternal iron deficiency and delayed neonatal auditory maturation and altered cochlear synaptic energy metabolism: analysis from a mother-infant observational study, mouse models, and cochlear explants.\nAbstract: Iron is a key nutrient for the development of the fetal auditory system. However, the potential impact of non-anemic prenatal iron deficiency (ID) on neonatal auditory function remains unclear. This study aimed to systematically explore the potential mechanisms by which maternal ID may affect auditory maturation of offspring. We analyzed population data from 696 mother-infant pairs, established ID mouse models (C57BL/6\u202fJ) during pregnancy, and conducted cellular experiments. In the human cohort, maternal serum ferritin (SF) and hemoglobin (Hb) were significantly negatively associated with the latency (ms) of auditory brainstem response (ABR) waves I, III, and V, as well as intervals (ms) of waves I-III, III-V, and I-V and summating potential/action potential ratios (%). Neonatal SF partially mediated the association between maternal iron status and auditory function, with mediation effects ranging from 28.57 to 76.32%. In mouse models, prenatal ID was associated with decreased wave I amplitude and extended latency in offspring, along with reduced ribbon synapses in inner hair cells, mitochondrial damage, and decreased enzyme activity in supporting cells. A metabolomics analysis revealed significant downregulation of pyruvate levels in the ID group, and exogenous supplementation with sodium pyruvate partially restored ribbon synaptic function. Collectively, prenatal ID may reduce fetal iron reserves, impair energy metabolism of cochlear supporting cells, inhibit ribbon synaptic maturation, and potentially contribute to auditory dysfunction. Our findings suggest that non-anemic maternal ID may be associated with delayed neonatal auditory maturation, highlighting the potential importance of iron intervention during pregnancy for improving neonatal auditory outcomes; however, causal relationships cannot be established from the observational human data, and the animal/cellular findings should be interpreted as supportive evidence requiring further validation.\n\nID: 42400972\nTitle: Neonatal brain-age models in full- and preterm infants.\nAbstract: Prematurity affects brain development and increases risk for neurodevelopmental impairments. Yet reliable biomarkers for at-risk infants remain limited. We developed brain-age prediction models using diffusion magnetic resonance imaging-derived white matter features from two datasets: (1) the developing Human Connectome Project (dHCP; 368 healthy infants) and (2) a clinical sample collected at the Lucile Packard Children's Hospital (LPCH; 162 high-risk preterm infants). The goals of this study were (1a) to construct a white matter neonatal brain-age model including full-term and preterm neonates from a large research data set, (1b) to evaluate the accuracy of a separate brain-age model using the same architecture but trained and evaluated via cross-validation on a restricted subset of very preterm infants (<32 weeks gestational age) from the same data set to improve comparability with our clinical cohort; (2) to determine if a similar model can predict brain-age based on clinical MRI scans from high-risk neonates born preterm; and (3) to evaluate whether this preterm white matter-based brain-age model provides information about the infant's health beyond conventional clinical and demographic measures. White matter features demonstrated strong predictive performance in the dHCP dataset (within 3.9 days) and the LPCH clinical dataset (within 6.6 days). However, brain-age metrics (i.e., brain-age gap) showed no significant associations with health complications measured by a composite score of common prematurity complications. While tractometry-derived brain-age models accurately characterize brain maturation in the neonatal brain, their sensitivity to clinical complications in preterm infants appears limited. Global white matter maturation measures derived from clinical grade data may be insufficiently sensitive to capture the cumulative burden of prematurity-related morbidities, suggesting need for multimodal or longitudinal biomarkers.\n\nID: 42400445\nTitle: Altered autonomic balance drives the increase in cardiac output and arterial pressure during convulsive seizures in nonanesthetized sheep.\nAbstract: Preclinical and human studies suggest that ictal and interictal modulation of the sympathetic and parasympathetic systems contributes to cardiovascular changes that may induce sudden unexpected death in epilepsy. We therefore investigated the effects of convulsive seizures on cardiovascular and autonomic function in nonanesthetized sheep. Adult female sheep were instrumented to record arterial pressure, heart rate, electroencephalogram, electrocardiogram, and either cardiac output or cardiac and renal sympathetic nerve activity (SNA). Arterial blood samples were collected to assess blood biochemistry. Seizures were induced in nonanesthetized sheep by intravenous infusion of the proconvulsant pentylenetetrazol (PTZ; 5.0\u2009mg/kg/min for 4\u2009min). PTZ induced consistent generalized tonic-clonic seizures associated with abnormal activity on electroencephalogram. Convulsive seizures increased mean arterial pressure (79.1\u2009\u00b1\u20094.5\u2009mmHg to 128.5\u2009\u00b1\u20095.6\u2009mmHg, p\u2009<\u2009.0001) and cardiac output (4.1\u2009\u00b1\u2009.2 to 7.9\u2009\u00b1\u2009.5\u2009L/min, p\u2009<\u2009.0001) at 10\u2009min postseizure; these remained significantly above baseline for 60\u2009min (both n\u2009=\u200912). Heart rate variability decreased (4826.1\u2009\u00b1\u2009766.6 to 210.9\u2009\u00b1\u200997.7\u2009ms, n\u2009=\u20096, p\u2009=\u2009.0155) at 10\u2009min and corrected QT interval increased (399\u2009\u00b1\u20099.1 to 449.7\u2009\u00b1\u200911\u2009ms, p\u2009=\u2009.003) at 30\u2009min postictally. Seizures increased cardiac SNA (682\u2009\u00b1\u200986 to 7558\u2009\u00b1\u20093955 spikes/min, n\u2009=\u20094, p\u2009=\u2009.007), whereas renal SNA decreased (4296\u2009\u00b1\u2009784 to 1139\u2009\u00b1\u2009284 spikes/min (p\u2009=\u2009.047). Seizures decreased blood potassium (3.9\u2009\u00b1\u2009.1 to 3.4\u2009\u00b1\u2009.1\u2009mmol\u00b7L-1, p\u2009=\u2009.0268) and increased lactate (.68\u2009\u00b1\u2009.05 to 12.2\u2009\u00b1\u20091.39\u2009mmol\u00b7L-1; p\u2009<\u2009.0001). Seizures induced by PTZ in nonanesthetized sheep caused autonomic and cardiovascular disturbances, including postictal tachycardia and arrhythmias, which may contribute to an increased risk of sudden unexpected death in epilepsy.\n\nID: 42395632\nTitle: Milk fat globule membrane in early-life nutrition: composition, production, and biological effects on infant immune maturation, intestinal development, neurocognitive function, and growth.\nAbstract: The milk fat globule membrane (MFGM) is a trilayered structure encasing fat globules in mammalian milk, primarily composed of phospholipids, glycoproteins, and bioactive molecules. Recent research indicates that MFGM plays a fundamental role in early-life health, particularly through its effects on gut microbiota development and immune system maturation. In the initial months of life, the infant's gut microbiome undergoes rapid colonization, essential for immunological tolerance, metabolic programming, and pathogen defense. Numerous studies have shown that MFGM components, including sphingomyelin, gangliosides, and glycoproteins, exhibit prebiotic-like effects by facilitating the proliferation of beneficial bacteria, such as Bifidobacterium and Lactobacillus species. Furthermore, MFGM supplementation in infant formulas has been linked to microbiota profiles that more closely resemble those of breastfed infants, enhanced gastrointestinal function, cognitive development, and a decreased incidence of diseases. This review clarifies how MFGM influences gut microbiota regulation, including increased barrier function, anti-inflammatory properties, and pathogen defense. Moreover, it highlights the possibility of MFGM-enriched dietary approaches to enhance proper gut colonization and promote long-term infant health, particularly in formula-fed populations. Although the results are encouraging, more longitudinal and mechanistic investigations are necessary to comprehensively clarify the influence of MFGM on the gut microbiome and the microbiota-mediated health benefits for growth and development.\n\nID: 42390352\nTitle: Early-life gut microbiome-metabolome development trajectories in Chinese infants: a decentralized real-world evidence study.\nAbstract: The neonatal period is a critical stage of development during which the gut microbiome profoundly influences both short- and long-term health and nutrition. Its maturation from infancy to childhood is shaped by interacting environmental factors, including feeding mode, birth mode, and geographic location. A clinical study of 445 infants and toddlers (aged 0-24 months) from six socioeconomically diverse regions in China investigated age-related trajectories of gut microbiome and metabolomic development, with a particular focus on feeding mode. The study included a breastfed reference group and a formula-fed group that received an open-label formula containing a prebiotic mixture of short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides (scGOS/lcFOS, 9\u2009:\u20091). Longitudinal fecal samples were analyzed using shotgun metagenomic and metabolomic approaches. Feeding mode was strongly associated with variations in gut microbiome structure and function, along with birth mode and geographic location. Bifidobacterium and Bacteroides were the dominant taxa in both groups and exhibited dynamic abundance trajectories over time. Increased Bifidobacterium abundance was correlated with gene functions involved in starch and fatty acid metabolism as well as the fructose-6-phosphoketolase pathway (Bifid shunt). Comparative metabolomic analyses of amino acids and bile acids revealed highly similar metabolic profiles between the two groups. These findings highlight the association between feeding mode with the developing gut microbiome and describe age-dependent trajectories in Chinese children.\n\nID: 42384215\nTitle: Age and seasonality in Hirschsprung-associated enterocolitis risk: a longitudinal cohort study.\nAbstract: Hirschsprung-associated enterocolitis (HAEC) remains a major cause of morbidity, with poorly defined triggers and limited modifiable risk factors. Given the roles of immune immaturity and mucosal dysfunction in HAEC pathogenesis, this study evaluated whether age is associated with HAEC risk, and whether seasonal variation consistent with viral exposure is present. A retrospective cohort study was conducted including patients with HD treated at Children's Hospital Colorado (2008-2021). A piecewise exponential Poisson regression model estimated age-specific HAEC incidence rates, adjusting for Trisomy 21 and length of aganglionosis. Seasonal distribution was assessed using an exact binomial test comparing cold (October-March) versus warm months. Among 217 patients, 96 HAEC episodes were identified in 53 patients (24.4%). HAEC incidence was highest in the first year of life and declined progressively with age, with an 88% reduction in patients older than 36 months (RR 0.12, 95% CI 0.07-0.22, p\u2009<\u20090.001). Additionally, 60.4% of episodes occurred during cold months, exceeding expected distribution (p\u2009=\u20090.03). HAEC risk is strongly age-dependent, with a marked reduction after 36 months, supporting a role for immune maturation in disease susceptibility. The observed seasonal pattern suggests that viral exposures may act as triggers in susceptible patients.\n\nID: 42380651\nTitle: Delayed maturation of the milk microbiome in women with type 1 diabetes.\nAbstract: The breastmilk microbiome plays a crucial role in gut microbial colonisation and immune development, but little is known about how it is influenced by type 1 diabetes. We conducted a longitudinal 16S rRNA gene sequencing study of milk from women with type 1 diabetes (n=69 pregnancies; 174 samples) and women who did not have type 1 diabetes (n=49 pregnancies; 123 samples), collected at seven timepoints from birth to 15 months postpartum. Alpha diversity (richness, inverse Simpson evenness) was analysed by generalised linear mixed models, beta diversity was analysed by Bray-Curtis dissimilarities and PERMANOVA, and differential abundance was analysed by limma. Additionally, we examined associations with maternal genetic risk score (GRS), maternal HLA type, glycaemic management (HbA1c) and breastmilk secretory IgA (sIgA), and performed a parallel analysis for the infant stool microbiome. A significant interaction between type 1 diabetes status and timepoint was observed for alpha diversity, both richness (p=0.01) and inverse Simpson diversity (p=0.003), indicating distinct temporal trajectories between women with and without type 1 diabetes. In those without type 1 diabetes, richness increased significantly between birth and 1\u00a0week postpartum, but this early increase was delayed in women with type 1 diabetes to between 1\u00a0week and 3\u00a0months postpartum (p=0.002). Beta diversity analysis revealed earlier and more extensive compositional shifts in women without type 1 diabetes compared to those with type 1 diabetes. These differences persisted after adjusting for Caesarean delivery, BMI, parity and infant sex, and were not attributable to a delay in initiating breastfeeding. Taxa with delayed enrichment in women with type 1 diabetes included Streptococcus spp. and Rothia mucilaginosa, which metabolise human milk oligosaccharides to short-chain fatty acids to promote development of the infant's gut barrier and immune system. Maternal GRS, HLA, HbA1c or sIgA were not associated with milk microbiota diversity trajectories. In infant stool samples, alpha diversity did not differ between exposure groups, and showed no evidence of delayed maturation. Beta diversity revealed an early compositional shift between birth and 1\u00a0week postpartum only in infants born to women without type 1 diabetes. Similarly, significant taxonomic changes between birth and 1\u00a0week postpartum were detected only in infants born to women without type 1 diabetes, but with some taxa differing between exposure groups at 1\u00a0week. Maternal type 1 diabetes is associated with delayed early maturation of the breastmilk microbiome. Early compositional differences in microbiota restructuring were also observed in the infant gut, partially mirroring the pattern in the milk microbiome; however, sustained differences in infant gut microbiota diversity were not detected. Further investigation could determine whether these changes affect development of the infant's gut and immune system.\n\nID: 42373621\nTitle: Mapping histologic and functional maturation of human endocrine pancreas across early postnatal periods.\nAbstract: Human endocrine cell differentiation and islet morphogenesis play critical roles in determining islet cell mass and function, but the events and timeline of these processes are incompletely defined. To better understand early human islet cell development and maturation, we collected 123 pediatric pancreata and mapped morphological and spatiotemporal changes from birth through the first ten years of life. Using quantitative analyses and a combination of complementary tissue imaging approaches, including confocal microscopy and whole-slide multiplex imaging, we developed an integrated model for endocrine cell formation and islet architecture, including endocrine cell type heterogeneity and abundance, endocrine cell proliferation, and islet vascularization and innervation. We also assessed insulin and glucagon secretory profiles in isolated islet preparations from pediatric donors aged 2 months to 10 years and found a temporal difference in the maturation of insulin secretion compared to glucagon secretion. This comprehensive summary of postnatal and pediatric pancreatic islet development provides a framework for future studies and for integrating emerging genetic and genomic data related to islet biology and diabetes risk.\n\nID: 42368744\nTitle: Neighborhood disadvantage and brain myelination: Insights from infancy to childhood.\nAbstract: Early life adversity (ELA), including poverty and socioeconomic disadvantage, can negatively impact neurodevelopment and long-term health outcomes. Here, we examined associations between neighborhood-level disadvantage, indexed by the Area Deprivation Index (ADI), and white matter myelination in infants and children aged 0-10 years (n = 61 MRI acquisitions across 43 children). Quantitative MRI-derived longitudinal relaxation rates (R1) are sensitive to myelin content and were used to assess white matter development. Higher ADI national percentiles (reflecting greater neighborhood disadvantage) were associated with lower R1 in several white matter regions, including the internal capsule, corona radiata, cingulate gyrus, fronto-occipital fasciculus, superior longitudinal fasciculus, and uncinate fasciculus. Whole-brain voxel-wise analyses further supported negative associations between ADI and myelination. These findings were stronger in the infant subsample and implicate white matter pathways supporting cognitive, socioemotional, and motor functions, suggesting that early environmental disadvantage may influence neurodevelopmental trajectories. Future work should examine which components of ADI drive these associations and how resilience may buffer the effects of disadvantage.\n\nID: 42368283\nTitle: What's that noise-tackling sound pollution in the NICU: a systematic review.\nAbstract: Preterm infants are highly susceptible to environmental influences due to the immaturity of their sensory and neurological systems. In neonatal intensive care units (NICUs), ambient noise frequently exceeds recommended thresholds and may interfere with auditory and neurodevelopmental maturation. During a critical period of sensory refinement, infants are exposed to unpredictable, high-intensity soundscapes generated by alarms, respiratory devices, and staff activity, contrasting sharply with the regulated acoustic environment of the womb. This systematic review aimed to identify, describe, and categorize noise sources in the NICU and to examine their potential impact on preterm infants. A systematic search across six major databases [MEDLINE, Embase, APA Psychinfo, CINHAL, Scopus, Web of Science (WOS); 2000-2026] identified studies reporting 24-h noise levels, day-night variation, and differences between incubator-internal and external sound. Eligible studies were synthesized and visualized using forest, strip, and dot plots, interpreted relative to American Academy of Pediatrics (AAP) recommendations. From 113 included studies, most reported sound levels substantially above recommended limits. Alarms, staff conversations, and incubator-associated equipment were consistently identified as major contributors. Respiratory support devices produced the highest internal noise levels, at times exceeding overall NICU ambient noise. Interventions such as staff training, behavioral adjustments, and environmental modifications yielded short-term improvements but rarely produced sustained reductions. NICU noise is a modifiable risk factor with significant developmental implications. Future strategies should integrate environmental design, technological innovation, and infant-focused interventions at the incubator-device interface to create safer, developmentally supportive acoustic conditions. Evidence also suggests that excessive shielding may reduce meaningful auditory input, raising concerns about potential auditory deprivation.\n\nID: 42363866\nTitle: Early antibiotic exposure and vaccine immune responses in preterm infants: potential sex-specific differences.\nAbstract: Neonatal sepsis represents a major risk in preterm infant care, resulting in widespread early-life antibiotic exposure. While the latter has been linked to immune maturation in term-born neonates, its impact on preterm immune development remains unclear. The aim of this prospective observational study was to investigate the effect of early antibiotic exposure on vaccine titers at a corrected age of four months. To achieve this, blood and stool samples were analyzed from 69 preterm infants (<32 weeks gestational age; 35 with 34 without antibiotic exposure during the first postnatal week) at postnatal day 14 and again at four months corrected age. We assessed vaccine-induced antibody titers against Bordetella pertussis and Haemophilus influenzae, immune cell profiles (flow cytometry), gut microbiome composition (16S rRNA sequencing), and plasma amino acid and acylcarnitine levels (tandem mass spectrometry). Preterm infants exposed to early antibiotics showed reduced antibody titers following vaccination, with differences appearing more pronounced in girls. Antibiotic-exposed girls displayed increased monocytes and myeloid-derived suppressor cells (MDSCs), both of which inversely correlated with antibody titers. Early antibiotic exposure was associated with differences in microbial community types at postnatal day 14, with Klebsiella-dominated and Bifidobacteria-lacking communities occurring more frequently in antibiotic-exposed infants. Antibiotic-exposed girls exhibited distinct metabolomic alterations, including elevated levels of two unsaturated fatty acids that negatively correlated with monocyte and MDSC abundance. Our findings suggest that early antibiotic exposure impairs vaccine responses in preterm infants and indicates a potentially sex-specific susceptibility. Antibiotic-driven changes in the microbiome and metabolome may sustain suppressive innate immune cell populations, which may in turn weaken adaptive responses to vaccination.\n\nID: 42363351\nTitle: Exploring the association between breastfeeding and the risk of developing autism spectrum disorders.\nAbstract: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with rising prevalence globally, including Pakistan. While genetic factors substantially contribute to ASD risk, environmental and early-life nutritional factors are also being investigated. One such factor is infant feeding practices specifically breastfeeding, its duration and exclusivity. Human breast milk provides comprehensive protection via providing essential nutrients with immune defence and neurobiological regulation supporting optimal brain development. Despite these benefits, breastfeeding rates in Pakistan remain low. This mini-review explores the existing literature on the potential link between breastfeeding and ASD with a focus on epidemiological evidence and underlying biological mechanisms. While some studies suggest that breastfeeding may reduce the risk of ASD, the evidence is inconclusive due to methodological differences, recall bias, and cultural factors. Data from low- and middle-income countries is lacking and call for an urgent need for robust longitudinal research in Pakistan to better study this association and guide costeffective public health strategies.\n\nID: 42362409\nTitle: Enteral nutrition to optimize health and neurodevelopmental outcomes in very preterm infants.\nAbstract: Very preterm infants are born before a critical window of nutrient accrual that occurs during the third trimester, resulting in a nutritional deficit that is vital to restore to support further growth and development. Although the gut is underdeveloped, optimizing administration of nutrition via the enteral route has been linked to improved long term outcomes, particularly when mother's own milk is prioritized as the initial source of nutrition. The goal of this review was to synthesize current evidence on best enteral nutrition practices for very preterm infants focusing on strategies that optimize long term neurodevelopment and infant health outcomes. This review examines the physiological importance of early enteral nutrition to support growth and neurodevelopment of very preterm infants. Clinical outcomes data related to different types of enteral nutrition sources are reviewed, as well as evidence-based practices regarding initiation of enteral nutrition, advancement, supplementation and fortification. Additionally, limitations in the existing literature are identified to inform future research directions. The collective evidence reviewed in this manuscript supports early, consistent, and human milk-based enteral nutrition as a central modifiable factor to improve growth, brain development, and long-term neurodevelopmental outcomes. While there are remaining uncertainties regarding the ideal timing for initiation, specific advancement strategies, and fortification methods, the available data supports the following: minimizing enteral fasting, prioritizing mother's own milk, and using protocolized feeding guidelines.\n\nID: 42361912\nTitle: Infant EEG preprocessing pipelines: A capability framework and current gaps in practice.\nAbstract: Infant electroencephalography (EEG) is essential for understanding early brain development, yet presents unique challenges including frequent movement artifacts, low signal-to-noise ratio, and rapid developmental changes. Specialized preprocessing pipelines have been developed to address these issues, but no structured cross-pipeline evaluation of their capabilities currently exists. This article presents a capability framework for ten prominent infant EEG preprocessing tools - nine infant-specific tools (APICE, Adjusted-ADJUST, GADS, NEAR, HAPPE, HAPPE+ER, HAPPILEE, BEAPP, and MADE) and the Modular pipeline, a general-purpose approach scalable to infant data - organized around five capability dimensions: artifact handling, automation and scalability, flexibility and adaptability, developmental sensitivity, and validation against empirical data. The framework is proposed as an exploratory evaluative heuristic, not a definitive taxonomy. For each dimension, each pipeline was assigned a maturity level from 1 (minimal documented support) to 5 (fully demonstrated, well-documented, and developmentally appropriate support), based on predefined anchored descriptors applied independently by two raters (overall Krippendorff's \u03b1 =.69), with lower agreement on the Automation and Validation dimensions - a pattern consistent with field-level ambiguity about what constitutes strong performance on these dimensions. No single pipeline reached the highest maturity level across all five dimensions; each occupies a distinct profile aligned with particular research needs. Notably, no pipeline achieved level 5 on either developmental sensitivity or validation against empirical data, indicating a field-wide gap in developmental calibration and cross-dataset validation. This capability framework provides a structured foundation for researchers and clinicians to make informed, context-sensitive preprocessing decisions in infant EEG studies.\n\nID: 42357971\nTitle: Culture Optimization of the IPEC-J2 Piglet Jejunum Cell Line for Applications in Infant Nutrition Research.\nAbstract: The intestinal porcine epithelial cell line (IPEC-J2) is a nontransformed jejunal model derived from unsuckled piglets. It is increasingly used in gut physiology research, yet its application to nutrient absorption remains underexplored. Four media types were assessed for their ability to support IPEC-J2 barrier maturation and permeability: Dulbecco's modified Eagle medium/Ham's F-12 with 10% fetal bovine serum (FBS10), 10% porcine serum (PS10), 5% porcine serum (PS5) supplemented with Wnt3a-R-spondin-Noggin conditioned medium (PS5+L-WRN), and PS5 with epidermal growth factor and insulin-transferrin-selenium (PS5+EGF+ITS). Culture medium influenced epithelial phenotype, with more than a 30-fold range in transepithelial electrical resistance (TEER), which plateaued by day 12. PS10 supported a balanced profile, characterized by intermediate TEER (2395.00\u00a0\u00b1\u00a0485.51\u00a0\u03a9\u00a0\u00d7\u00a0cm2), lowest lactulose and mannitol permeability (p\u00a0<\u00a00.05), high lactate dehydrogenase activity (p\u00a0<\u00a00.05\u00a0vs. PS5+L-WRN and FBS10), enhanced membrane localization of tight junction proteins (p\u00a0<\u00a00.05\u00a0vs. PS5+EGF+ITS), and reduced fibroblast marker S100A4 (p\u00a0<\u00a00.05\u00a0vs. PS5+EGF+ITS). Treatment with digested infant milk formula did not compromise barrier integrity in PS10-cultured IPEC-J2 monolayers and enabled transport of free amino acids to the basolateral compartment. These findings support IPEC-J2 as an alternative to Caco-2 cells for applications in infant nutrition research in vitro.\n\nID: 42356243\nTitle: Association Between Donor Human Milk Initiation Timing and Necrotizing Enterocolitis, Mortality, and Feeding Outcomes in Very-Low-Birth-Weight Infants: A Multicenter Retrospective Cohort Study Using Two Japanese Registries.\nAbstract: Background/Objectives: Early enteral feeding in preterm infants remains controversial because, despite promoting intestinal maturation, concerns about necrotizing enterocolitis (NEC) persist. Donor human milk (DHM) is recommended when the mother's milk is unavailable, but the optimal initiation timing is unclear. This study evaluated the association between DHM initiation timing and outcomes in very-low-birth-weight (VLBW) infants in Japan. Methods: This multicenter retrospective cohort study used data from a national human milk bank registry (2018-2023) and the Neonatal Research Network of Japan (NRNJ; 2022). Infants with birth weight <1500 g were categorized by DHM initiation timing (\u226424, 25-48, or >48 h), with infants in the NRNJ cohort serving as the comparison group. The primary outcome observed was NEC incidence, including all stages; secondary outcomes included in-hospital mortality and time to full enteral feeding. Bayesian regression models were applied. Detailed feeding data were unavailable in the NRNJ cohort. Results: Among 2962 infants, NEC incidence was low across groups. NEC occurred in 1.31% of the \u226424 h DHM group and 1.83% of the NRNJ group, with mortality rates of 4.53% and 6.23%, respectively. Although NEC incidence was numerically lower in the \u226424 h DHM group, estimates were imprecise because of limited events. Early DHM initiation was associated with lower in-hospital mortality and earlier full enteral feeding, particularly in infants with <1000 g birth weight. Conclusions: Early DHM initiation was associated with lower mortality and earlier achievement of full enteral feeding in VLBW infants without elevated NEC risk. However, because detailed feeding information was unavailable in the comparison cohort, these associations should be interpreted cautiously. Given the observational design and heterogeneous nutritional exposures, further prospective studies are warranted.\n\nID: 42353337\nTitle: A Systematic Review on the Association Between Water Fluoride Levels and Dental Fluorosis: Exploring the 'Halo Effect' and Confounding Environmental Factors.\nAbstract: Dental fluorosis (DF) remains a global public health challenge traditionally attributed to elevated water fluoride F-. However, the Halo Effect and environmental factors now complicate this dose-response relationship. Following PRISMA 2020 guidelines, this systematic review identified 20 observational studies (n = 21,780) via PubMed, Scopus, and Web of Science. Inclusion logic utilized the PICOS framework, specifically selecting human studies that reported quantitative water F- levels alongside environmental or dietary confounders. Quality was assessed via the Newcastle-Ottawa Scale. Synthesis revealed that in optimal fluoridated areas (0.7 mg/L), mild DF prevalence reached 15-20% in cohorts with high \"Halo Effect\" exposure (infant formula, processed beverages) a twofold increase over historical benchmarks. High altitude (>2000 m) and arid climates further exacerbated toxicity by altering renal clearance. These factors sustain systemic fluoride levels that inhibit protease activity (MMP-20/KLK4) and induce endoplasmic reticulum stress during enamel maturation, causing hypomineralization. Current water-centric monitoring is insufficient for modern risk assessment. A transition toward Total Daily Intake (TDI) models and context-specific standards accounting for altitude and dietary diffusion is essential to balance caries prevention with systemic safety.\n\nID: 42341995\nTitle: Heterozygous gain-of-function and mixed-type Kcna2 variants recapitulate SUDEP and increased cortical Npy-Npy1r signaling.\nAbstract: Variants in the KCNA2 gene are associated with developmental and epileptic encephalopathy and are classified as loss-of-function, gain-of-function (GoF), or mixed-type based on electrophysiological characteristics. Although Kcna2 knockout mice exhibit epilepsy, the pathogenic mechanisms underlying GoF and mixed-type variants remain poorly understood. This study compared GoF and mixed-type models to investigate their underlying molecular mechanisms. CRISPR-edited heterozygous mice carrying R297Q or L290R variants were generated. Seizure activity was monitored and characterized using simultaneous video-EEG-ECG recordings. Cortical single-cell transcriptomic analysis was performed to demonstrate pathogenic mechanisms and associated regulatory pathways. R297Q and L290R heterozygous mice developed spontaneous lethal seizures within 1-2\u00a0months, with median survival times of 52 and 49\u00a0days, respectively. No overt motor deficits or brain malformations were observed. Video-EEG-ECG monitoring of R297Q mice revealed frequent Racine stage 2-3 seizures, with the most severely affected mouse exhibiting head nodding almost every minute, while stage 4-5 seizures were less common. All monitored mice eventually experienced lethal stage 5 seizures, characterized by postictal generalized EEG suppression followed by bradycardia and cardiac arrest, producing a terminal pattern that resembled human sudden unexpected death in epilepsy (SUDEP). Interictal ECG analysis demonstrated increased skipped beats and elevated heart rate variability, suggesting autonomic dysfunction. Single-cell transcriptomic analysis showed that R297Q selectively affected specific neuronal subtypes while L290R induced widespread changes, yet both variants converged on synaptic pathway disruption. In addition, enhanced NPY signaling was identified in both models, reflected in upregulation of Npy1r. GoF and mixed-type KCNA2 pathogenic variants converged on a seizure-induced premature death phenotype that recapitulated SUDEP and a shared cortical Npy-Npy1r signaling pathway. Enhanced Npy-Npy1r signaling may represent a potential therapeutic target for KCNA2-related epilepsies.\n\nID: 42341186\nTitle: Parietal thickness predicts middle temporal area (V5) motion responses in 7-year-old children born very preterm.\nAbstract: Very preterm birth has been associated with altered brain development and impaired global motion processing within the dorsal visual stream. We explored whether cortical thickness in occipital and parietal regions predicted global motion processing in 7-year-old children born very preterm. Structural magnetic resonance imaging (MRI) measures were successfully computed for 99 children, motion coherence thresholds were evaluated in 85 participants and functional MRI blood oxygen level-dependent (BOLD) percent signal change in the primary visual cortex (V1) and/or middle temporal area (V5) was quantifiable in 23 participants. Parietal cortical thickness predicted V5 BOLD response to 100% coherent motion stimuli, where individuals with thinner parietal cortices had stronger V5 BOLD responses to coherent motion. These findings indicate that parietal thickness may serve as a structural indicator of dorsal stream development in children born very preterm and provide a structural basis for understanding individual differences in global motion processing.\n\nID: 42339597\nTitle: The infant gut microbiota: a narrative review about development and external determinants.\nAbstract: This narrative review examines the development of the infant gut microbiota during the early months of life, highlighting the impact of delivery mode and feeding practices on microbial colonization and overall infant health. The search was conducted using the Virtual Health Library and PubMed databases, with the descriptors \"gut microbiota\" combined with \"breastfeeding\" (BF) and \"infant formula.\" After screening, 18 articles were selected for final analysis. Findings indicate that cesarean section reduces initial gut microbial diversity by 30%-50% and decreases Bifidobacterium colonization, while increasing the abundance of Enterobacteriaceae and Clostridium. In contrast, exclusive BF supports a more favorable microbial profile, enriched in bifidobacteria, and contributes to immune system maturation. The literature also highlights the importance of other genera, including Lactobacillus, Veillonella, and Firmicutes, in regulating inflammation, producing short-chain fatty acids, and protecting against pathogens. Supporting vaginal birth and exclusive BF emerges as a key strategy to promote a more resilient and health-promoting gut microbiota during infancy.\n\nID: 42473832\nTitle: Can Health Insurance Mandates and Tax Credits Reduce Coverage Gaps and Out of Pocket Cost in Small Island Developing States? Modelling the Eastern Caribbean.\nAbstract: Rising out-of-pocket (OOP) health expenditures in the Eastern Caribbean Currency Union (ECCU) underscore persistent gaps in health insurance coverage. This paper develops a Health Insurance Policy Simulation Model (HIPSM) to assess the potential impact of employer health insurance mandates and health insurance tax credits (HITCs) across five small island developing states (SIDS): Antigua and Barbuda, Dominica, Grenada, St. Lucia, and St. Vincent and the Grenadines (SVG). Using social security and insurance data, the model estimates coverage gains, fiscal costs, and labour market effects under varying thresholds and tax credit levels. Results show that employer mandates and HITCs can reduce coverage gaps and OOP expenditure in these countries but are highly sensitive to design characteristics. The findings offer important guidance for SIDS exploring scalable pathways towards universal health coverage through private insurance mechanisms, particularly in the absence of comprehensive public healthcare financing systems.\n\nID: 42465128\nTitle: Multi-systemic diseases with cardiac involvement: insights from two clinical cases.\nAbstract: Systemic inflammatory diseases (SIDs) can present with a wide range of cardiac manifestations, which, although uncommon, are frequently associated with significant morbidity and poor prognosis. Beh\u00e7et's disease and antiphospholipid syndrome (APS) are two distinct immune-mediated disorders encompassed within this spectrum, both capable of causing intracardiac thrombi and systemic embolisation, which causes diagnostic and therapeutic challenges. While Beh\u00e7et's disease is a classic systemic inflammatory vasculitis, APS primarily represents a prothrombotic autoimmune disorder with variable inflammatory features. This case series highlights two patients with cardiac involvement in SIDs, emphasising the importance of early recognition, individualised treatment strategies, and a multi-disciplinary approach to optimise outcomes in these complex clinical scenarios.\n\nID: 42461965\nTitle: The antiviral GTPase MxB is packaged into virions and binds via its N-terminal domain to alphaherpesvirus capsids.\nAbstract: The interferon-inducible myxovirus resistance proteins (Mx) belong to the dynamin-like GTPases; MxA is a restriction factor against several RNA viruses, while MxB restricts infections of lentiviruses and herpesviruses. Humans express MxA(1-662) with an N-terminal domain (NTD) of 43 residues, MxB(1-715) with an NTD of 91 residues, and a truncated MxB(26-715) with an NTD of 66 residues. Although the roles of the GTPase and stalk domains during infection are increasingly being elucidated, the functions of the different NTDs remain poorly understood. Using cell lines stably expressing Mx proteins, we show that MxB(1-715), but not MxA, inhibited infection by herpes simplex virus (HSV-1) and pseudorabies virus (PrV). Quantitative mass spectrometry and subviral fractionation experiments indicate that MxB(1-715), but not the truncated MxB(26-715) or MxA(1-662), was enriched in the tegument of HSV-1 and PrV virions. Moreover, dimeric, recombinant, chimeric proteins with the NTD peptides MxB(1-91) or MxB(1-35), and to a lesser extent MxB(26-91), bound to tegumented HSV-1 capsids, while MxA(1-43) did not. In contrast, de-tegumented HSV-1 and PrV capsids bound to proteins with MxB(1-91), but not to those with MxB(1-35) or MxA(1-43). Our findings indicate that the NTD of MxB is crucial to restrict HSV-1 and PrV infections, that newly assembled virions package MxB into the tegument around the capsid, and that both the N-terminal MxB amino acid residues 1-25 and 26-91 contribute to its binding to tegumented and de-tegumented herpesviral capsids.\n\nID: 42435214\nTitle: The Right to Grieve: Norwegian Women's Experiences of Care During Termination of Pregnancy in Second Trimester.\nAbstract: This study examines women's experiences of interacting with healthcare professionals after receiving serious prenatal information around gestational week 18 and through subsequent late pregnancy loss, including termination of pregnancy, intrauterine foetal death, or miscarriage. It focuses on medical guidance, emotional support, and post-birth care. A qualitative descriptive design was used. Five Norwegian women participated in individual in-depth interviews, providing insight into encounters with healthcare professionals across the care trajectory. Their experiences unfolded across four key moments: learning about the diagnosis, making a decision, giving birth, and leaving the hospital. Care was experienced as fragmented, intensifying emotional distress and uncertainty. Shifts between clinical and emotionally attuned language created cognitive dissonance, leading the women to question the legitimacy of their grief and maternal identity. These findings highlight the need for coordinated psychosocial and medical care that acknowledges maternal identity and affirms women's right to grieve.\n\nID: 42429296\nTitle: Safer Sleep Guidance in Standalone UK Smartphone Apps for Parents of Newborns and Infants: Systematic mHealth App Review.\nAbstract: Parents are increasingly using smartphone apps to help guide decision-making around aspects of caregiving, including safer sleep. However, it remains unclear whether the guidance provided aligns with best practice guidelines. This review aimed to identify smartphone apps that provide safer sleep guidance and to assess their content, technical features, functionality, and quality. A secondary aim was to make recommendations on the improvements that existing and future apps can make to provide safer sleep guidance. In January 2026, we searched the UK Google Play Store and Apple App Store for safer sleep guidance apps for parents and caregivers of newborns and infants (babies aged \u226412 months). Information regarding content, technical features, and functional features was extracted and summarized descriptively. Each app was evaluated by 2 raters using the Mobile App Rating Scale (MARS) and the IMS Institute for Healthcare Informatics functionality score. Adherence to best practice sleep guidance was assessed using bespoke criteria. Interrater reliability was calculated. A total of 1345 apps were identified, with 12 meeting the inclusion criteria. All were free to download, with 42% (5/12) containing in-app purchases. Only 17% (2/12) were affiliated with a professional health, medical, clinical, or government body. All 12 apps contained some information regarding safer sleep practices, although this was addressed and named differently (eg, calling it cot death, sudden infant death syndrome, or safe sleep). Of the 9 criteria relating to safer sleep best practice guidance, the apps mentioned an average of 6.75 (SD 1.71; range 3-9) criteria. Some promoted unsafe sleep practices (ie, around swaddling and cosleeping). The apps included an average of 5.4 of the 11 IMS functionality criteria (SD 2.5; range 2-9). The mean MARS score was 3.7 out of 5 (SD 0.43; range 2.92-4.13), and most (11/12, 92%) had a minimum acceptability score of 3 or above. Two had been formally trialed or tested. Although the language used was considered accessible (easy to understand), none of the apps allowed the language to be changed (beyond English), and very few (3/12, 25%) enabled users to change to night/dark mode, which would be considered essential when using these apps at night. Several apps about safer baby sleep exist. Few discuss safer sleep guidance comprehensively or raise awareness about sudden infant death syndrome and its links with unsafe sleep. All the reviewed apps met the minimum acceptability criteria for quality; however, not many were formally trialed or tested. More long-term research should be conducted on the effectiveness of safer sleep apps on adherence to safer sleep guidance. We recommend that apps relating to infant and baby safety in general include information on realistic safer sleep practices that are informed by best practice guidelines and take a risk minimization approach.\n\nID: 42423462\nTitle: The targeted cytosolic degradation of class I histone deacetylases is essential for efficient alphaherpesvirus replication.\nAbstract: Viral infection triggers a robust DNA damage response (DDR), reshaping the host chromatin landscape to facilitate viral replication. Here, we uncover a novel mechanism by which alphaherpesviruses exploit the DDR pathway. We demonstrated that herpes simplex virus 1 (HSV-1) and pseudorabies virus (PRV) induced selective degradation of class I histone deacetylases (HDAC1/2), leading to histone hyperacetylation and subsequent DDR activation. Strikingly, viral infection promoted nuclear export of HDAC1/2, followed by MDM2-mediated K63-linked polyubiquitination and proteasomal degradation in the cytoplasm. Pharmacological inhibition of either DDR signaling or HDAC1/2 nuclear export significantly affected viral replication in vitro and in vivo. Our findings reveal a unique viral strategy to hijack host epigenetic regulation for efficient replication, and identify potential therapeutic targets for alphaherpesvirus infections.\n\nID: 42415628\nTitle: Bovine Lactoferrin Inhibits Pseudorabies Virus Attachment Through Blockade of Glycoprotein C-Heparan Sulfate Interaction.\nAbstract: Pseudorabies virus (PRV) is an important swine pathogen that causes significant economic losses in the pig industry. In addition to its swine host, PRV also infects a wide variety of animals as well as humans, posing a threat to veterinary public health. Thus, the development of potent antiviral drugs against PRV is required. Bovine lactoferrin (BLF) is widely known as an iron-binding glycoprotein in the transferrin family, which gains great attention for biomedical applications due to its beneficial physiological functions to human health as an antioxidant, antimicrobial, antiviral, anticancer, and immunomodulatory agent. In the work described here, we identified BLF as a novel and potent antiviral agent against PRV. BLF exhibited strong antiviral activity against PRV infection in multiple pig, human, and mouse permissive cells. Systematic analysis of the effect of BLF on PRV inhibition revealed that BLF blocks PRV attachment to target cells. Through surface plasmon resonance (SPR) analysis, BLF was demonstrated to directly interact with heparan sulfate (HS) proteoglycan (HSPG), a primary attachment receptor for PRV. Addition of exogenous HS completely abolished BLF inhibition of PRV attachment, demonstrating that BLF represses PRV attachment by interacting with cell-surface HS. However, BLF failed to inhibit the attachment of a PRV mutant virus with the deletion of glycoprotein C (gC), the primary viral envelop component for HS binding, suggesting that PRV gC is required for BLF inhibition of PRV infection. Cumulatively, these findings demonstrated that BLF inhibits PRV attachment by binding cell-surface HS to block the interaction between viral gC and HS.\n\nID: 42409384\nTitle: Marked Decline in Bearded Pig (Sus barbatus) Detections in Sabah, Malaysia, during the African Swine Fever Outbreak, 2021.\nAbstract: African swine fever (ASF) has recently swept through Southeast Asia, beginning in 2018, posing a significant threat to populations of native wild pig species. In Borneo, the population of wild bearded pigs (Sus barbatus) declined sharply during the period of regional ASF spread. This paper presents results of WWF-Malaysia surveys of bearded pigs in the Malaysian state of Sabah, in the northern part of Borneo, that showed changes over a 6-yr period (2019-25), starting before the 2021 ASF outbreak. Surveys were conducted along 2-km transects at 28 sites across 10 forest reserves and parks by using a combination of camera trapping and direct observations. The findings revealed high bearded pig occurrence in 2019-20, with a mean of 12.67 pigs per 100 camera-trap nights, followed by a precipitous decline from March 2021 to December 2022 and a slight increase in detections from 2023 onward. These results documented a marked decline of at least one order of magnitude in bearded pig detections across Sabah that coincided with the period of regional ASF spread, and they showed continued low populations even 5 yr after the epidemic was initially recorded. The survey findings provide an important ecologic baseline for monitoring bearded pig populations and highlight the need for integrated wildlife-disease surveillance in the region.\n\nID: 42400311\nTitle: Purification and concentration of model viruses using single-pass tangential flow filtration.\nAbstract: The vaccine and viral vector industry is growing at an accelerated rate. To improve harvest and purification processes, the development of continuous membrane-based operations, such as normal flow filtration (NFF) and single pass tangential flow filtration (SPTFF) for concentration were explored. This work was conducted using two model viruses, non-enveloped porcine parvovirus (PPV) and enveloped Suid herpesvirus (SuHV). The viruses are in the same family as the gene therapy vectors adeno associated virus and herpes simplex virus, respectively. SPTFF design started with batch TFF for membrane selection. Hollow fiber membranes with a 100 and 300\u2009kDa molecular weight cut off were defined for PPV and SuHV SPTFF operations, respectively. The SPTFF runs for PPV did not provide any concentration of the virus and low protein and DNA removal, unlike batch TFF. Two hollow fiber membranes run at 10\u2009mL/min and 2\u2009psi were the best condition for SuHV concentration, with approximately 100-fold titer concentration and protein and DNA removal of 37%\u2009\u00b1\u20095% and 32%\u2009\u00b1\u20098%, respectively. This concentration was superior to the batch TFF and indicated a strong dependence on flow rate and transmembrane pressure. For NFF, filters selection and performance tests were carried out for NFF of PPV and SuHV, as well as cleaning protocols for hollow fiber membranes. The ultimate goal is to integrate this work into the continuous purification of viral vectors produced in mammalian cell cultures to reduce costs and increase throughput.\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\u2019s complementary-but-disjoint (A-B-C) model.

Despite advances in diagnostic techniques, many cases are still classified as unexplained and labeled as sudden infant death syndrome (SIDS). Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination. A narrative review of the literature (2000-2026) was conducted using PubMed and Scopus, focusing on under-recognized causes of SUDI and their diagnostic implications. Relevant studies were selected and organized into major pathological and forensic categories. Hidden causes of SUDI include a wide spectrum of conditions. Cardiac disorders-such as myocarditis, cardiomyopathies, and inherited arrhythmogenic syndromes-are frequently implicated and may require molecular autopsy for detection. Infectious diseases, often presenting with minimal or nonspecific findings, represent another important category, particularly viral and bacterial infections. Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses. Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control. Environmental, toxicological, and medico-legal factors-including unsafe sleep conditions, toxic exposures, and inflicted injury-must also be considered. SUDI is a multifactorial entity in which many unexplained deaths may be attributable to identifiable but overlooked conditions. A standardized, multidisciplinary approach integrating autopsy, ancillary investigations, and molecular diagnostics is essential to improve diagnostic accuracy and support prevention strategies.\n --- END ACTUAL ABSTRACT FOR 42279599 ---\n\n- ERROR: You cited ID: 42017742 for the quote: \"Forensic investigation of sudden unexplained death has long been a challenging issue due to its insidiousness and complex pathological basis.\"\n FACT: Strict Misquote Detected!

The neurobiological mechanisms involved remain unclear. We investigated the role of wake-promoting Orexin (Ox) and Histamine (HA) neurons in SIDS. Cerebrospinal fluid (CSF) Ox levels were measured in 61 living controls and 70 Sudden Unexpected Death Infants (SUDI: 38 SIDS, 32 explained deaths (ED)). HA and tele-methylhistamine (t-MeHA) were analyzed in an additional 46 SUDI (34 SIDS, 12 ED) and 42 controls. Immunohistochemistry was performed on hypothalamic tissue from 11 SIDS and 8 ED cases to quantify Ox and HA neuron numbers. CSF Ox levels did not differ overall between groups but were higher in SUDI infants aged 2-6 months. HA and t-MeHA levels were elevated in SUDI, likely reflecting postmortem release. Ox neuron numbers were increased in rostral hypothalamic region in SIDS compared with EDs, whereas HA neuron numbers were unchanged. SIDS is associated with increased Ox neuronal activity during the peak risk period, possibly reflecting a homeostatic upregulation in response to arousal deficit or repeated stress or hypoxia, while the role of HA system remains to be clarified with more sensitive biomarkers. First study evaluating orexin and histamine systems in SIDS using CSF and postmortem brain tissue. Identifies elevated orexin activity in SIDS infants, particularly in the 2-6 month risk window. No evidence to date for direct histamine involvement; need for more sensitive biomarkers. Suggests orexin system as a potential biomarker for SIDS risk stratification. Highlights the importance of combined neurobiological approaches for prevention.\n --- END ACTUAL ABSTRACT FOR 42332249 ---\n\n- ERROR: You cited ID: 42279599 for the quote: \"Cardiac disorders\u2014such as myocarditis, cardiomyopathies, and inherited arrhythmogenic syndromes\u2014are frequently implicated and may require molecular autopsy for detection.\"\n FACT: Strict Misquote Detected!

However, maternal anxiety may influence how effectively this awareness translates into confident caregiving. Parenting self-efficacy is a determinant of maternal behavior, yet the mechanisms linking SIDS awareness and self-efficacy remain unclear. To examine the relationship between SIDS awareness and parenting self-efficacy among mothers of infants and to investigate the mediating role of maternal anxiety. A cross-sectional study was conducted among 335 mothers of infants aged 0-12 months attending six primary healthcare facilities in Mansoura, Egypt. Data were collected using validated scales that measure SIDS awareness, postpartum anxiety, and parenting self-efficacy. Pearson correlations, mediation analysis, and multiple linear regression were performed. SIDS awareness was positively associated with parenting self-efficacy (r = 0.57, p < 0.001) and negatively associated with maternal anxiety (r = -0.18, p < 0.001). Anxiety was inversely related to self-efficacy (r = -0.31, p < 0.001). Mediation analysis revealed that maternal anxiety partially mediated the relationship between SIDS awareness and parenting self-efficacy. Nurse-led care should combine safe sleep education with routine screening and management of maternal anxiety. Reassurance-focused communication and brief psychosocial support during postnatal visits may strengthen maternal confidence and improve adherence to safe infant care practices. Maternal anxiety partially shapes how SIDS awareness influences parenting self-efficacy. Integrating emotional support with SIDS education may strengthen maternal confidence and improve safe infant care practices.\n --- END ACTUAL ABSTRACT FOR 41950602 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Sudden infant death syndrome (SIDS) occurs predominantly during sleep between 2 and 6 months of age, suggesting impaired maturation of arousal pathways.\" (Source: 42332249)\n- \"The pathogenetic mechanisms underlying the fulminant course of infection in infants leading to fatal outcomes remain insufficiently understood.\" (Source: 42196581)\n- \"Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination.\" (Source: 42279599)\n- \"Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control.\" (Source: 42279599)\n- \"Sudden Unexpected Death in Infancy (SUDI) is the term given to all unexpected infant deaths, comprising accidental, non-accidental and natural deaths including Sudden Infant Death Syndrome (SIDS).\" (Source: 41582236)\n- \"Infectious diseases, often presenting with minimal or nonspecific findings, represent another important category, particularly viral and bacterial infections.\" (Source: 42279599)\n- \"Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses.\" (Source: 42279599)\n- \"This study identifies a focal site in the human motor thalamus where electrical stimulation suppresses involuntary, automatic breathing and induces apnea without awareness.\" (Source: 42003135)\n- \"An altered reelin expression is hypothesized as a contributor to altered DG morphology.\" (Source: 41508915)\n- \"SUPC was associated with early unsupervised skin-to-skin care and bed sharing.\" (Source: 42444072)\n- \"The obtained data demonstrate substantial differences between the observed changes and the classic presentation of COVID-19 in older children.\" (Source: 42196581)\n- \"The normal post-mortem fundus in children under two years old shows a \"central retinal artery occlusion\" pattern, followed by the appearance of macular or peripheral white radial retinal folds\" (Source: 42061094)\n- \"The grey literature component aimed to expand understanding beyond built food environments and food retail and to promote epistemic justice by including traditionally excluded voices, knowledge and experiences.\" (Source: 42349911)\n- \"The Metabolic Vulnerability Index (MVI) operationalizes the TCF as a five-domain ordinal scoring system (0-15).\" (Source: 41938522)\n\n\nINSTRUCTION: Study the actual abstracts provided.

However, qualitative explorations are lacking, especially within culturally diverse settings. This study aims to explore the beliefs on the mechanisms of the relationship between diet, food systems, and mental health, and the lived experience of such, through a case study of one Caribbean Small Island Developing State, to inform culturally grounded public health strategies that integrate nutritional and psychological well-being. Fifteen interviews with food system stakeholders and five focus groups with the general public were conducted. Transcripts were analyzed using a grounded theory approach with a critical realist epistemological stance. Four major categories centered on beliefs of mechanistic effects of diet on mental health, as well as broader perspectives of the relationship between food systems, food experiences, and mental health. Participants believed that (1) unhealthy diets of processed and chemically treated foods contribute to poor mental health and that (2) food insecurity is a key threat to mental health, but they also believed that (3) consumption of locally produced foods and (4) residing in agricultural communities can be beneficial to mental health. Participants recognize that diet influences mental health through physiological, social, and structural pathways, but this connection is threatened by rising dependence on imported, processed foods. Along with complementary quantitative research, the findings highlight the potential of expanding nutritional health literacy and clinical guidance and strengthening local food systems and traditional diets for mental well-being among Caribbean Small Island Developing States.\n --- END ACTUAL ABSTRACT FOR 42124028 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Sudden infant death syndrome (SIDS) occurs predominantly during sleep between 2 and 6 months of age, suggesting impaired maturation of arousal pathways.\" (Source: 42332249)\n- \"Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination.\" (Source: 42279599)\n- \"Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control.\" (Source: 42279599)\n- \"The pathogenetic mechanisms underlying the fulminant course of infection in infants leading to fatal outcomes remain insufficiently understood.\" (Source: 42196581)\n- \"Sudden Unexpected Death in Infancy (SUDI) is the term given to all unexpected infant deaths, comprising accidental, non-accidental and natural deaths including Sudden Infant Death Syndrome (SIDS).\" (Source: 41582236)\n- \"Infectious diseases, often presenting with minimal or nonspecific findings, represent another important category, particularly viral and bacterial infections.\" (Source: 42279599)\n- \"Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses.\" (Source: 42279599)\n- \"This study identifies a focal site in the human motor thalamus where electrical stimulation suppresses involuntary, automatic breathing and induces apnea without awareness.\" (Source: 42003135)\n- \"An altered reelin expression is hypothesized as a contributor to altered DG morphology.\" (Source: 41508915)\n- \"SUPC was associated with early unsupervised skin-to-skin care and bed sharing.\" (Source: 42444072)\n- \"The obtained data demonstrate substantial differences between the observed changes and the classic presentation of COVID-19 in older children.\" (Source: 42196581)\n- \"The normal post-mortem fundus in children under two years old shows a \"central retinal artery occlusion\" pattern, followed by the appearance of macular or peripheral white radial retinal folds\" (Source: 42061094)\n- \"The grey literature component aimed to expand understanding beyond built food environments and food retail and to promote epistemic justice by including traditionally excluded voices, knowledge and experiences.\" (Source: 42349911)\n- \"The Metabolic Vulnerability Index (MVI) operationalizes the TCF as a five-domain ordinal scoring system (0-15).\" (Source: 41938522)\n- \"Human endocrine cell differentiation and islet morphogenesis play critical roles in determining islet cell mass and function, but the events and timeline of these processes are incompletely defined.\" (Source: 42373621)\n- \"NICU noise is a modifiable risk factor with significant developmental implications.\" (Source: 42368283)\n- \"Recent development and application of molecular autopsy have provided crucial support for addressing this problem.\" (Source: 42047799)\n- \"Children born in areas with the most deprivation had a higher risk of underattainment compared with those in areas with the least deprivation\" (Source: 42446880)\n- \"Approximately half of all SUPC cases involved possible or definite airway obstruction, which - compared with other aetiologies - was more often related to preventable factors like reduced maternal vigilance and covering of the infant's nose and mouth.\" (Source: 41911090)\n\n\nINSTRUCTION: Study the actual abstracts provided.

While many cases are labeled Sudden Infant Death Syndrome (SIDS) after extensive investigation, emerging evidence indicates that underlying, previously \"hidden\" pathological conditions\u2014ranging from metabolic disorders and cardiac channelopathies to subtle neuropathological and immune-metabolic constraints\u2014often contribute to these events. The integration of molecular autopsy and multidisciplinary diagnostic frameworks is essential to uncover these overlooked mechanisms.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe phenomenon of Sudden Unexpected Death in Infancy (SUDI) is defined by its unexpected nature and its complex diagnostic path, often involving \"Sudden Infant Death Syndrome (SIDS)\" as a diagnosis of exclusion. \"Sudden Unexpected Death in Infancy (SUDI) is the term given to all unexpected infant deaths, comprising accidental, non-accidental and natural deaths including Sudden Infant Death Syndrome (SIDS).\" Mechanistically, SIDS occurs during a vulnerable developmental window, where \"Sudden infant death syndrome (SIDS) occurs predominantly during sleep between 2 and 6 months of age, suggesting impaired maturation of arousal pathways.\" Research into the biological basis of these deaths reveals that \"Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination.\" These may involve genetic, infectious, or metabolic substrates. For instance, \"Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses.\" Furthermore, environmental and behavioral factors, including sleep position, co-sleeping, and soft bedding, can contribute to asphyxia. \"Approximately half of all SUPC cases involved possible or definite airway obstruction, which - compared with other aetiologies - was more often related to preventable factors like reduced maternal vigilance and covering of the infant's nose and mouth.\" Neuropathological assessment is critical as \"Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control.\" Given these complexities, a multidisciplinary approach incorporating molecular diagnostics and forensic neuropathology is necessary to transition from \"unexplained\" to identified, preventable causes.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The human motor thalamus contains a focal region (VLa/VA nuclei) capable of suppressing automatic breathing without awareness, a potential node in the pathogenesis of central apnea disorders like SIDS.\n* \"Hidden\" causes of death often include myocarditis and inherited arrhythmogenic syndromes, which are frequently missed without molecular autopsy.\n* Maternal type 1 diabetes is linked to delayed maturation of the breastmilk microbiome, an external determinant affecting early-life immune development.\n* Specific biomarkers, such as UCH-L1 in cord blood, are showing potential as early indicators of fetal cellular stress and neurodevelopmental risk.\n* Recent longitudinal research suggests that gut dysbiosis in neonates can persist into adulthood, potentially contributing to neurodevelopmental vulnerability.\n* The use of radiofrequency electrical conductivity in MRI imaging reveals a distinct biophysical dimension of perinatal brain development beyond water mobility.\n* Post-mortem fundus photographs exhibit specific patterns, such as macular folds, which are associated with longer post-mortem intervals rather than necessarily indicating trauma.\n* Noise pollution in the NICU is a major modifiable factor; alarms and staff activity create an acoustic environment often substantially above recommended guidelines.\n* The \"Metabolic Vulnerability Index\" is a new, structured framework allowing for the assessment of five-domain physiologic constraints in infant deaths.\n* Socioeconomic deprivation, as indexed by the Area Deprivation Index, is significantly associated with altered white matter myelination trajectories in children from infancy through childhood.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"41416934": "ID: 41416934\nTitle: \"Whose mother am I?\" Maternal identity reconstruction among bereaved mothers of infants who died of SIDS.\nAbstract: The term sudden infant death syndrome (SIDS) refers to the unexpected and medically unexplained death of an infant, typically during sleep. This study examines how maternal identity is reconstructed among 14 Jewish Israeli mothers who experienced the loss of a baby to SIDS. We began with the assumption, well-grounded in modern grief models, that loss undermines the bereaved identity and in the case of SIDS the undermine of maternal identity is likely to be intensified due to the perceived failure to protect the infant, the ambiguity of a medically unexplained death, and often the dismissive societal responses. Drawing on in-depth semi-structured interviews and employing a narrative analytic approach, the findings reveal that reconstruction of maternal identity is a dynamic, non-linear process that oscillates across three dimensions adapted from Van Gennep's rites of passage framework: separation, liminality, and integration. The third dimension is conceptualized as a continuum ranging from a split maternal identity to a more integrated sense of self - a unified maternal identity. Implications for mental health professionals supporting bereaved mothers are discussed.",

CCHS is caused by heterozygous PHOX2B mutations, predominantly polyalanine repeat expansion (95% of cases) and, less frequently, frameshift mutations (5%). To address the lack of disease models, we generated five human induced pluripotent stem cell (hiPSC) lines derived from patients carrying\u00a0+5Ala, +6Ala and\u00a0+11Ala expansion mutations. These hiPSC lines exhibited undifferentiated hPSC phenotype, pluripotency, normal karyotype, and retention of the pathogenic genotype, providing a reliable in vitro platform for elucidating CCHS molecular mechanisms and disease pathogenesis.",
"41422643": "ID: 41422643\nTitle: Abandoned, lost and otherwise discarded fishing gear in the Caribbean SIDS of Trinidad and Tobago.\nAbstract: Abandoned, lost and otherwise discarded fishing gear (ALDFG) is a contributor to marine plastic debris in the Caribbean. This study focused on ALDFG in the Caribbean Small Island Developing State (SIDS) of Trinidad and Tobago, by exploring the problem, its causes and the existing management framework to inform evidence-based interventions. The specific objectives were to estimate the amount of plastic waste entering the coastal/marine environment as a result of ALDFG, identify hotspots of ALDFG accumulation, determine the causes of fishing gear loss, document practices used by fishers to avoid gear loss, explore fishers' perceptions of ALDFG and assess the legislative, regulatory and policy gaps in the management of ALDFG. We find that gillnets, hooks and lines, traps and fish aggregating devices (FADs) used in artisanal fisheries in Trinidad and Tobago can get lost and enter the environment. This lost gear is likely to end up in the Exclusive Economic Zone (EEZ) of neighbouring Caribbean States. The causes of gear loss and damage were identified as a combination of conflict-based (high traffic of other vessels, conflict with other gear, vandalism) and environmental (gear snagged on obstructions, damage or towing by large animals, strong currents) factors. A suite of interventions (prevention, mitigation, remediation) is available to address the issue. Given its transboundary nature, national, regional and international action is crucial.",

Focusing on safety related to Sudden Unexpected Infant Death (SUID) and comfort associated with infant development and thermoregulation, we examine mattress firmness, pressure distribution, breathability, and thermal properties. Since infants have difficulty turning over and possess immature thermoregulatory functions, mattress characteristics directly influence sleep quality and safety. Based on international studies, we clarify the requirements for infant mattresses and provide insights into future product development and evaluation standards.",
"41475408": "ID: 41475408\nTitle: Sudden Unexpected Infant Death and Safe Sleep Practices.\nAbstract: Sudden unexpected infant death (SUID) is the primary cause of post-neonatal mortality. SUID disproportionately affects preterm infants and infants admitted to the neonatal intensive care unit (NICU). NICU providers are charged with ensuring the implementation of safe sleep practices and caregiver education while balancing other acute medical needs. The persistent lack of improvement in sleep-related infant deaths and the release of updated recommendations from the American Academy of Pediatrics (AAP) have reinvigorated institutional and public health efforts to reduce SUID. In\u00a0this review, we will discuss the nomenclature, epidemiology (including racial and ethnic disparities in SUID), and pathophysiology of sleep-related infant deaths. Finally, we will review the updated AAP recommendations on safe sleep and early transition to safe sleep in the NICU.",
"41501081": "ID: 41501081\nTitle: Multi-access edge computing scheduling optimization model for remote education under 6G network environment based on reinforcement learning.\nAbstract: The evolution of digital education necessitates robust computational frameworks to address the complexities inherent in remote learning environments. Traditional scheduling mechanisms often fall short in accommodating the dynamic nature of learner engagement and the asynchronous delivery of content. To bridge this gap, we introduce a novel computational model that leverages reinforcement learning to optimize content delivery schedules. Central to our approach is the Attentive Stochastic Transition Estimation Network (ASTEN), which models the probabilistic transitions of learner states, accounting for factors such as attention variability and feedback delays. Complementing ASTEN is the Selective Informative Delivery Strategy (SIDS), a decision-theoretic framework that determines optimal content emission based on real-time uncertainty assessments and pedagogical utility. Our approach captures nuanced behavioral trends, such as sporadic learner interaction, temporal learning decay, and individualized attention cycles, thereby enabling a more responsive and tailored instructional strategy. By explicitly integrating cognitive and behavioral signals within the scheduling framework, our model facilitates the delivery of content that aligns with each learner's evolving state. Empirical evaluations demonstrate that our integrated model significantly enhances learning outcomes by adapting to individual learner trajectories and mitigating the challenges posed by sparse feedback. This research contributes to the theoretical foundations of computational learning models and offers practical insights for the development of adaptive educational technologies, particularly in environments where traditional one-size-fits-all approaches prove inadequate.",
"41508915": "ID: 41508915\nTitle: Reelin in the Infant Hippocampus, and Relationship to Sudden Infant Death Syndrome (SIDS) and Dentate Gyrus Morphology.\nAbstract: Morphological features within the hippocampal dentate gyrus (DG) granule cell layer (GCL) have been identified in some cases of sudden unexpected infant death (SUDI), including sudden infant death syndrome (SIDS). Reelin, an extracellular matrix protein, is critical in neuronal migration and cell positioning. An altered reelin expression is hypothesized as a contributor to altered DG morphology. This study aimed to determine whether the number of reelin-expressing cells within the infant hippocampus is altered in (1) SIDS, and according to the presence of (2) SIDS risk factors (age, cigarette smoke exposure [CSE], sleep position, bed sharing, and upper respiratory tract infection [URTI]), and (3) DG morphology. Immunohistochemical staining of reelin was quantified (measured as the number of positive reelin cells/mm2) within the layers of the DG, CA4/Hilus, CA3-CA1, and subiculum in cases of explained SUDI (eSUDI, n\u2009=\u200912), SIDS I (n\u2009=\u20097), and SIDS II (n\u2009=\u200933). Reelin was highly correlated with age. After adjusting for age, SIDS II infants had a lower number of reelin immunopositive cells in the CA1, a finding that was more pronounced in bed sharers. Analysis of risk factors indicated lower reelin in the DG and CA3 of males, and in the DG of infants with URTI (when excluding bed sharers). The presence of the DG morphological feature of cluster ectopic cells was associated with a lower number of reelin cells across several hippocampal layers, whereas gaps were associated with higher numbers, with layers predominantly affected being the DG molecular layer and CA2 stratum radiatum.",
"41515176": "ID: 41515176\nTitle: Diet and Mental Health Relationships in Caribbean Populations: A Scoping Review and Evidence Gap Map.\nAbstract: Background/Objectives: Most research linking diet and mental health outcomes is from high-income countries, limiting insight into how these relationships manifest in culturally diverse, vulnerable contexts, such as the Caribbean. This scoping review aims to map existing research on the relationship between aspects of diet and mental health within Caribbean populations, to identify evidence gaps and guide future research. Methods: Eleven databases were searched for studies published between 2000 and 2024 in 33 Caribbean countries which assessed the relationship between diet and mental health outcomes. Duplicate screening and extraction were conducted using Redcap software, and a narrative synthesis and evidence gap map were created. The original protocol was registered with Open Science Framework. Results: Forty-four records were included, nine of which focused on eating disorders (examined separately). Most were cross-sectional studies of the general population, with few experimental and qualitative studies. Surveys were the most frequently applied data collection tool, often without mention of local adaptation or validation. Most records examined food security and depression as their 'diet' and 'mental health' variables, respectively. Frequently explored relationships included autism and seafood intake and fruit and vegetable intake, while depression and food security was the most widely examined relationship across studies. Conclusions: Caribbean research on diet-mental health relationships is growing though it is limited in scope, design, and cultural validity. Strengthening this evidence base requires studies whose primary aim is in nutritional psychiatry, using culturally relevant tools, and an expansion of study designs that incorporate Caribbean food systems and sociocultural contexts surrounding diet and mental health.",
"41582236": "ID: 41582236\nTitle: Characteristics of infant deaths with positive hair toxicology.\nAbstract: Sudden Unexpected Death in Infancy (SUDI) is the term given to all unexpected infant deaths, comprising accidental, non-accidental and natural deaths including Sudden Infant Death Syndrome (SIDS). As in other developed countries, Australian SUDI rates are relatively low, but incidence rates have remained essentially unchanged since 2004. To increase our understanding of these deaths, we reviewed a cohort of SUDI cases with positive hair toxicology, focussing on toxicology results, pathology findings, and SIDS risk factors.\u00a0All infant deaths between 1st January 2014 and 31st of December 2023 with positive hair toxicology in the state of Victoria, Australia, were reviewed for toxicology results, pathology findings and SIDS risk factors.\u00a0A total of 99 infant deaths met the selection criteria. At least one SIDS risk factor was reported in every case, with a median of 5 per case, highlighting that these infants likely had a high cumulative risk for SIDS. Co-sleeping was most common, reported in over 75% of cases. Polysubstance use was high (87%), with a median of 4 drugs detected per case. Methylamphetamine was detected in hair in over half of cases (n\u2009=\u200957, 58%). Postmortem findings including serious illnesses, like pneumonia (p\u2009=\u20090.002), significant neuropathology (p\u2009=\u20090.002 and p\u2009=\u20090.035), low head circumference (<\u200915th percentile) (p\u2009=\u20090.035) and low body weight (<\u200915th percentile) (p\u2009=\u20090.022 and p\u2009=\u20090.011) were all positively correlated with drug exposure in hair.\u00a0Infants with positive hair toxicology appear to have a high cumulative risk for SIDS, which may reflect a chaotic home environment. Most postmortem findings were positively correlated with drug exposure.",
"41612838": "ID: 41612838\nTitle: Development of an educational intervention program for infant safe sleep practices in Korea: a methodological study.\nAbstract: Education on infant safe sleep practices has been known to reduce the risk of sleep-related sudden unexpected infant death. Since sleep environments may vary across sociocultural contexts, infant safe sleep education needs to reflect specific sociocultural settings. This study aimed to develop an educational Protocol for Infant Safe Sleep (PISS) for primary caregivers in Korea that considers parenting behaviors and cultural characteristics. This study was conducted in three key methodological steps: (1) retrieval, defining, and systematic classification of PISS content; (2) the structural formulation of the content as an educational protocol; and (3) content validation. For the first step, a literature review was conducted, along with an analysis of educational materials from institution websites related to infant safe sleep and online parenting communities. Field observations were also conducted to identify relevant Korean culture characteristics. Based on these findings, the PISS was developed. Content validity index was assessed by six professionals, and the results were reflected into the educational program. The PISS intervention provided an educational video and booklet and enhanced learning via phone counseling and educational kit, which comprised an illustrated safe sleep sticker and a calendar-style activity diary. The educational content consisted of (1) sleep location, (2) sleep position, (3) bedding, (4) clothes and temperature, and (5) other considerations. This study developed the PISS, an intangible educational intervention based on Korean sociocultural characteristics and specific guidelines for primary caregivers. Future research should evaluate the effectiveness of this program in promoting safe sleep practices.",
"41650217": "ID: 41650217\nTitle: Probabilistic mapping and automated segmentation of human brainstem white matter bundles.\nAbstract: Brainstem white matter (WM) bundles are essential conduits for neural signals that modulate homeostasis and consciousness. Their architecture forms the anatomic basis for brainstem connectomics, subcortical circuit models, and deep brain navigation tools. However, their small size and complex morphology, compared to cerebral WM, makes mapping and segmentation challenging in neuroimaging. As a result, fundamental questions about brainstem modulation of human homeostasis and consciousness remain unanswered. We leverage diffusion MRI tractography to create BrainStem Bundle Tool (BSBT), which automatically segments eight WM bundles in the rostral brainstem. BSBT performs segmentation on a custom probabilistic fiber map using a convolutional neural network architecture tailored to detect small anatomic structures. We demonstrate BSBT's robustness across diffusion MRI acquisition protocols with in vivo scans of healthy subjects and ex vivo scans of human brain specimens with corresponding histology. BSBT also detected distinct brainstem bundle alterations in patients with Alzheimer's disease, Parkinson's disease, multiple sclerosis, and traumatic brain injury through tract-based analysis and classification tasks. Finally, we provide proof-of-principle evidence for the prognostic utility of BSBT in a longitudinal analysis of traumatic coma recovery. BSBT creates opportunities for scalable mapping of brainstem WM bundles and investigation of their role in a broad spectrum of neurological disorders.",
"41724190": "ID: 41724190\nTitle: Sudden Unexpected Infant Death in Inclined Sleepers: 2009-2023.\nAbstract: In 2019, the Consumer Product Safety Commission (CPSC) recalled inclined sleepers following reports of infant deaths. In 2023, recalls were reannounced after additional reports of infant deaths. This study used child death review (CDR) data to describe sudden unexpected infant deaths (SUIDs) that occurred in inclined sleepers. We identified SUIDs that occurred in inclined sleepers from 2009 to 2023 from the Pediatric National Fatality Review-Case Reporting System (Pediatric NFR-CRS). Frequencies and proportions were calculated to describe demographic, incident, and supervisor characteristics. From 2009 to 2023, 158 SUIDs occurred in inclined sleepers. One hundred and eight deaths (68%) occurred from 2009 to 2019; 50 deaths (32%) occurred after 2019. Most infants were younger than 4 months (67%). Most incidents occurred at the infant's home (86%) under the supervision of a parent (83%). Nearly 30% were reported as placed supine to sleep and subsequently found unresponsive nonsupine. In 51 deaths (32%), the CDR team indicated the infant's airway was obstructed when found: 55% by the inclined sleeper material and 35% by other soft bedding in the sleep environment (not mutually exclusive). Infant deaths occurred in inclined sleepers even after the CPSC issued manufacturer recalls in 2019. Health care providers, home visitors, health insurers, and family-serving organizations should continue advising caregivers on the importance of a safe infant sleep environment, including use of a firm, noninclined surface, and avoidance of soft bedding. Improved dissemination of recalls of infant products that represent unsafe sleep environments may reduce the risk of sleep-related deaths.",
"41736199": "ID: 41736199\nTitle: Analysis of First and Second Sleep Environments in Unexplained Sudden Deaths in Infants Based on Scene Reenactment Data.\nAbstract: The American Academy of Pediatrics (AAP) recommends that a safe sleep environment consist of an infant lying supine on a separate, uncluttered, approved sleep surface. Infant awakenings may lead to moving the infant from the initial sleep environment to a second one. The Connecticut Office of the Chief Medical Examiner electronic database was searched from 2018 through 2022 for infant deaths with non-homicidal manner in which scene reenactments were performed; 87 such deaths were identified. The most common causes of death were unsafe sleep environments (64.4%) and asphyxia (21.8%). Of the total cases, 79.3% had a single sleeping environment and 20.7% involved a second. Of the second sleep environments, 77.8% were less safe than the initial sleep environment and 21.8% had evidence of airway obstruction when found unresponsive. Only 4.6% of the infants were in a recommended sleep location at any time during the last sleep. Infant awakenings do not often lead to movement to a second sleep environment, but when they do, the second environment is often less safe than the first. This study reinforces the importance that the sleep environment plays in infant deaths and that scene reenactments play in their investigation.",
"41758359": "ID: 41758359\nTitle: Infant Sleep Behavior Practices and Knowledge of Fathers: An Exploratory and Descriptive Study.\nAbstract: Sudden unexpected infant death (SUID) is a term for any sudden death occurring under 1 year of age. SIDS (sudden infant death syndrome) is the sudden death of an infant that is unexplained after an investigation and often occurs during sleep or in the infant sleep area. In Indianapolis, 130 infants died in 2022 before their first birthday, and 17% were from SUIDs. Fathers' understanding of infant safe-sleep knowledge and behaviors is mostly unknown. This study aims to describe fathers' infant safe-sleep knowledge and behaviors. Study participants were recruited via promotional flyers from 2019 to 2024. Volunteers completed a survey on their infant safe-sleep knowledge and behaviors. Responses were entered via secure, web-based data-collection tool either directly by QR code accessible survey or manually by the research team. Frequency and comparative analyses were performed, and results described. Eighty-five fathers completed the survey. The lowest reported knowledge for safe-sleep practices was for breastfeeding, and wearable blankets being protective against SUID. A smaller percentage of fathers reported their baby never slept in the same bed as someone else and similarly reported never placing their baby to sleep in an adult bed. Fewer fathers correctly reported practicing room-sharing and pacifier usage. Interactive learning geared toward male caregivers on AAP recommendations for preventing sleep-related deaths is key. Focusing efforts with fathers on the risk of soft bedding, benefit of breastfeeding, pacifier usage, and room-sharing will be important to lowering SUID rates and helping men in their role as fathers.",
"41763901": "ID: 41763901\nTitle: Strengthening peer support for families bereaved by sudden unexpected infant death: Development and evaluation of a standardized training course.\nAbstract: Sudden Unexpected Infant Death (SUID) is the leading cause of postneonatal mortality worldwide. Bereaved parents commonly seek peer support for bereavement-related needs, but competencies and standardized training for organizations offering peer facilitators are lacking. We developed and piloted a train-the-trainer curriculum addressing peer facilitators' knowledge, skills, and attitudes for supporting SUID-bereaved parents. A needs assessment of international peer support organizations and expert consensus from an international working group informed development of competencies and a curriculum. A 1.5-day in-person pilot of eight participants from five countries was conducted, followed by remote sessions. Pre- and post-training surveys assessed impact. Wilcoxon signed-rank tests analyzed outcomes; open-ended responses were descriptively summarized. Significant improvements in knowledge, skills, and attitudes (p < .05) were shown across 13 competencies, including grief literacy and group facilitation skills, suggesting the curriculum is feasible, acceptable, and effective. This train-the-trainer model may support scalable, global peer bereavement training.",
"41796078": "ID: 41796078\nTitle: Neuropathologic findings and age-related differences in Finnish pediatric medico-legal autopsies.\nAbstract: Neuropathological examination plays a critical role in medico-legal cause-of-death investigation, especially in determining the cause and manner of death in pediatric autopsies. Although a comprehensive neuropathological examination is recommended, limited data exists of the diagnostic yield of neuropathology consultations in such cases. This retrospective register-based study reviewed Finnish pediatric medico-legal autopsies from 2016 to 2022 involving full neuropathological examination performed by a neuropathologist, with a focus on age-related differences in consultation rates, themes, and diagnostic findings. Data were retrieved from the medico-legal cause-of-death investigation documents, and included background characteristics, neuropathologic diagnoses, and causes and manners of death. A total of 118 pediatric medico-legal autopsies with a neuropathology consultation were performed during the study period. The consultation rate was highest among infants (aged <1\u2009year; 45.6%), compared to early childhood (aged 1-10\u2009years; 23.0%) and late childhood (aged 11-18\u2009years; 6.2%). Traumatic brain injury was the most frequent consultation theme overall (33.9%), while the frequency of epilepsy-related consultations increased with age. Hypoxic-ischaemic neuronal injury constituted the commonest finding, with an overall prevalence of 43.2%. Findings associated with childhood epilepsy were more prevalent in early and late childhood, with epilepsy accounting for 15.2% of deaths in the latter group. Positive diagnostic findings were uncommon among infants, consistent with a high proportion of cases (42.1%) classified as sudden infant death syndrome. These findings provide forensic pathologists with age-specific diagnostic insights, supporting more targeted resource use and neuropathology consultation practices.",
"41845357": "ID: 41845357\nTitle: Abortion policy, political control, and maternal and infant mortality in the United States: a cross-sectional ecological study.\nAbstract: BACKGROUND: Maternal and infant mortality in the U.S. remain the highest among high-income nations, with disparities worsening after Dobbs v. Jackson Women\u2019s Health Organization. This study examined how abortion bans and partisan political control are associated with maternal and infant mortality, while accounting for sociodemographic, economic, and healthcare factors. METHODS: We conducted a cross-sectional ecological study of all 50 U.S. states, linking maternal mortality ratios (MMR) and infant mortality rates (IMR) with abortion policy classifications (total ban, ban at \u2264\u200918 weeks, ban after 18 weeks, no gestational ban) and partisan control of governors, legislatures, and senates. Multivariable regressions adjusted for sociodemographic, economic, and healthcare variables. RESULTS: Unadjusted analyses showed MMR and IMR were higher on average in Republican-led states (27 vs. 20 per 100,000; 6.3 vs. 5.0 per 1,000; all p\u2009<\u20090.01), with political control accounting for up to one-quarter of the variance (R\u00b2=0.21\u20130.25). In adjusted models, total abortion bans were correlated with higher MMR (\u03b2\u2009=\u20095.28, p\u2009=\u20090.0315, R\u00b2=0.81) and IMR (\u03b2\u2009=\u20091.15, p\u2009=\u20090.0014, R\u00b2=0.86). Higher mortality correlated with greater fertility and larger Black population shares; protective factors included higher income, state investment, education, life expectancy, Hispanic population, and healthcare access. These patterns clustered by party control. CONCLUSIONS: In this ecological analysis, abortion bans and Republican political control were correlated with higher maternal and infant mortality at the state level. While individual-level causality cannot be inferred, addressing structural disparities may help reduce preventable deaths. Maternal and infant deaths remain higher in the United States than in other wealthy countries. These problems have become worse since the Dobbs v. Jackson Women\u2019s Health Organization decision, which allowed many states to ban or restrict abortion. Our study looked at whether abortion laws and political control in each state are related to the number of women who die during or shortly after pregnancy (maternal mortality) and the number of infants who die before their first birthday (infant mortality).We studied all 50 states uosing publicly available data. We compared maternal and infant death rates with state abortion policies (from total bans to no gestational bans) and with whether Republicans or Democrats controlled the governor\u2019s office and state legislatures. We also considered other important factors such as income, education, access to healthcare, and racial/ethnic makeup of the population.We found that states with abortion bans and Republican political control had higher maternal and infant death rates than states without bans and with Democratic control. For example, maternal mortality was about one-third higher in Republican-led states. Higher fertility rates and larger Black populations were linked with more deaths, while protective factors included higher income, greater state investment, more education, longer life expectancy, and larger Hispanic populations.Our findings show that restrictive abortion policies and political control are linked with worse outcomes for mothers and infants. Although this type of study cannot prove direct cause, it highlights the need to address underlying inequalities to save lives.",
"41851818": "ID: 41851818\nTitle: Differences in heart DNA methylation between sudden infant death syndrome and other sudden deaths.\nAbstract: Sudden Infant Death Syndrome (SIDS) remains a leading cause of infant mortality worldwide, yet its underlying mechanisms are largely unknown. SIDS etiology is complex and involves the interplay between a vulnerable infant, a critical developmental period, and external stressors. Cardiac function, including cardiorespiratory autonomic control, is considered a major contributor to SIDS. Emerging evidence suggests that epigenetic modifications of heart tissue, particularly DNA methylation (DNAm), may contribute to SIDS risk. We conducted an epigenome-wide association study (EWAS) to determine if DNA methylation patterns of post-mortem heart tissue differ between SIDS cases and non-SIDS controls, and to evaluate the role of DNAm in timing of SIDS events. Using a case-control study design, we generated DNA methylation data using Illumina EPIC Methylation V2 arrays and performed single site EWAS, differentially methylated region (DMR), and epigenome network cluster analyses to assess differential DNA methylation between SIDS cases and non-SIDS controls. Post-mortem heart tissues from 324 infants (202 SIDS cases) were obtained from the Chicago Infant Mortality Study (CIMS) and the NIH NeuroBioBank (NBB). Inclusion criteria required SIDS cases to meet standardized SIDS definitions, as determined from a through case investigation (i.e., autopsy, death scene examination, and clinical history). Seven CpG sites were differentially methylated between SIDS cases and non-SIDS control (adjusted (adj.) p\u2009<\u20090.05). Two were located within DTNB (cg1703363; adj. p\u2009=\u20090.02) and NDUFS8 (cg12070987; adj. p\u2009=\u20090.02). There were two differentially methylated regions overlapping the KRTCAP3 and RUNX3 genes. Of the top ten most significant CpG-SIDS diagnosis interactions, two of them were located within mitochondrial genes, ACSL1 and AK2. This study identified differentially methylated CpG sites and regions from heart tissue in SIDS cases versus controls, notably in DTNB, NDUFS8, KRTCAP3, and RUNX3. Our findings highlight pathways enriched for mitochondrial function, immune cell regulation, and cardiac dysfunction, which indicate the heterogenous nature of SIDS and supports the need for larger multi-tissue collaborative studies to identify SIDS subtypes, underlying pathologies, and determine the causal nature of such findings.",
"41911090": "ID: 41911090\nTitle: Sudden Unexpected Postnatal Collapse in the Netherlands: A National Registry Study.\nAbstract: Sudden unexpected postnatal collapse (SUPC) is a rare and potentially life-threatening event with variable reported incidences, mostly derived from in-hospital data. This study investigated the incidence, aetiology, and circumstances of SUPC in the Netherlands and assessed differences between in-hospital and home settings. Data concerning SUPC cases were obtained through a web-based registry managed by the Dutch Paediatric Surveillance Unit from April 2019 to April 2022. SUPC was defined as a collapse within 24 h of birth requiring resuscitation with at least positive pressure ventilation in infants born at \u226535 weeks of gestation and with a 5-min Apgar score \u22658. Of 94 registered SUPC cases, 60 met inclusion criteria: 52 cases occurred in hospital and 8 at home. The annual incidence ranged between 7 and 17 per 100,000 live births, with an average of 11 per 100,000. Median time to collapse was 64 min, with over two-thirds occurring within 2 h of birth. Collapses occurring at home occurred significantly later than those in hospital (165 min vs. 60 min; p < 0.05) and were associated with substantially higher mortality rates (37.5% vs. 6%; p < 0.05). Approximately half of all SUPC cases involved possible or definite airway obstruction, which - compared with other aetiologies - was more often related to preventable factors like reduced maternal vigilance and covering of the infant's nose and mouth. SUPC occurs in hospitals and at home, with later onset and higher mortality outside the hospital. Greater awareness and prevention are needed in both settings.",

However, the impact of variations in smoking behaviours, including timing, intensity, and cessation, remains understudied. This study examines the association between maternal smoking and SUID, incorporating detailed categorizations of smoking behaviours. We conducted a population-based, retrospective cohort study of live births in the United States from 2017 to 2021 using the Centre for Disease Control Linked Birth-Infant Death files. Maternal smoking was categorized as non-smoking, pre-pregnancy smoking only, trimester-specific smoking, continuous or discontinuous smoking, and cessation before the third trimester, with stratification by smoking intensity. SUID was defined using ICD-10 codes. Multivariable logistic regression was used to estimate unadjusted (OR) and adjusted odds ratios (aOR) for SUID. Sensitivity analyses examined mediation by gestational age and infant birth weight. Heavy continuous smokers had the highest aOR for SUID (372.8 per 100,000 births; aOR 2.81, 95% CI 2.67-2.94), followed by light continuous smokers (395.6 per 100,000 births; aOR 2.47, 95% CI 2.19-2.78) and discontinuous heavy smokers (292.5 per 100,000 births; aOR 2.29, 95% CI 1.72-3.00) compared with non-smokers. Pre-pregnancy-only smokers had the lowest odds of SUID among all smoking categories (light: 188.2 per 100,000 births; aOR 1.77, 95% CI 1.48-2.10; heavy: 152.8 per 100,000 births; aOR 1.61, 95% CI 1.44-1.78). In the sensitivity analysis, the natural indirect effect (NIE) of continuous smoking throughout pregnancy on SUID through gestational age and infant birth weight were insignificant (gestational age: \u03b2\u2009=\u20091.01, 95% CI 0.99-1.03, p\u2009=\u20090.28, infant birth weight: \u03b2\u2009=\u20091.04, 95% CI 0.99-1.08, p\u2009=\u20090.10). Maternal smoking significantly influences SUID, with earlier cessation exhibiting weaker associations. These findings emphasize the importance of early smoking cessation interventions to improve SUID outcomes.",
"41926549": "ID: 41926549\nTitle: Research at the Paris Foundling Hospital, Part 1: Until and during the Revolution.\nAbstract: The Paris Foundling Hospital was a breeding ground for neonatal medicine, but little is known about its research. During the century preceding the Revolution, admission of newborns rose dramatically, making this institution the largest infant hospital in the world. A total of 3,162 infants were admitted in 1742, of whom 40% died in the hospice and another 20% with the nurses. During the Revolution (1789-1804), monasteries were transformed into jails or hospitals, and the foundling hospital became a teaching institute. Students flocked to the capital, and those believed to qualify for hospital positions were selected through competing publications. A major research focus was trials of artificial nutrition, motivated by the fear of transmitting venereal disease to wet nurses via breastfeeding. Cows and goats were held on the premises, but milk was kept without refrigeration. A research branch of the foundling hospital was in Vaugirard, directed by Fran\u00e7ois Doublet. In 1781, he treated syphilitic newborns by wet-nursing them from syphilitic nurses treated with mercury. Another approach requiring considerable logistics was sending thousands of infants to the countryside for wet-nursing. In 1769, Joseph Raulin analyzed the mortality at the hospice and found that thrush, diarrhea, marasmus, suffocation, and inflammation were the major causes of death. Foundling hospital surgeon Jean-Abraham Auvity published prize-winning treatises on thrush and sclerema in 1786. He related skin hardening (sclerema) to postnatal hypothermia and developed warming techniques for premature infants. During the Revolution and Terror, meaningful research was conducted at the foundling hospital but failed to lower mortality.",
"41938522": "ID: 41938522\nTitle: CYP450 Constraints in Infants: A Multidomain Convergence Framework for Investigating Mechanistic Vulnerability.\nAbstract: Cytochrome P450 (CYP450) enzymes are the primary hepatic Phase I oxidative biotransformation system for many drugs and xenobiotics; variability in CYP capacity is therefore a key determinant of metabolic reserve. Reserve varies with developmental ontogeny, genotype, and acquired suppression (e.g., cytokine-mediated phenoconversion). Early infancy represents a developmental window in which clearance capacity and redox/energetic buffering may be comparatively constrained. We introduce a hypothesis-generating Three-Axis Convergence Framework (TCF) modeling interacting effects of (i) developmental/genetic reserve limits, (ii) immune-cytokine modulation of metabolism, and (iii) exposure/disposition context, and translate this synthesis into a structured postmortem interpretive tool integrated into the primary medicolegal autopsy, using an enhanced analytic panel applied selectively based on case context and specimen validity/QC to support mechanistic characterization of infant deaths remaining unexplained (often SUID/SIDS). A structured narrative synthesis was conducted spanning developmental pharmacology, pharmacogenetics, immunology, redox biology, neuropathology, and toxicology. Routine medicolegal postmortem practices used in SUID investigations were reviewed to identify measurement gaps that may limit mechanistic resolution in unexplained cases. The synthesis was formalized into five analytic domains: CYP450 capacity, immune/cytokine load, redox balance/energetics, neurochemical integrity, and xenobiotic/metal burden. The Metabolic Vulnerability Index (MVI) operationalizes the TCF as a five-domain ordinal scoring system (0-15). Domain 1 is anchored by hepatic CYP protein abundance (a more postmortem-stable proxy than CYP activity assays, which are generally constrained by rapid functional decay and QC limitations), normalized to adult reference and interpreted against age-matched developmental expectations. Domain-combination lookup tables route users to 14 mechanistically defined archetypes and specify modifier/exposure-context documentation. Appendices define an operational postmortem workflow, specimen validity rules, analytic QC constraints, detection limits, and a worked example. A Cytokine-Metabolic Suppression Profile (CMSP) is presented as an interpretive coherence summary and does not modify MVI scoring or certification. The MVI provides a structured framework for describing multidomain physiologic constraints in unexplained infant deaths alongside standard forensic practice. In this way, the TCF, MVI, and CMSP together offer a disciplined response to long-standing mechanistic uncertainty in early life-by enabling systematic measurement, coherent interpretation, and transparent identification of evidence gaps, rather than asserting new causes.",

However, maternal anxiety may influence how effectively this awareness translates into confident caregiving. Parenting self-efficacy is a determinant of maternal behavior, yet the mechanisms linking SIDS awareness and self-efficacy remain unclear. To examine the relationship between SIDS awareness and parenting self-efficacy among mothers of infants and to investigate the mediating role of maternal anxiety. A cross-sectional study was conducted among 335 mothers of infants aged 0-12\u00a0months attending six primary healthcare facilities in Mansoura, Egypt. Data were collected using validated scales that measure SIDS awareness, postpartum anxiety, and parenting self-efficacy. Pearson correlations, mediation analysis, and multiple linear regression were performed. SIDS awareness was positively associated with parenting self-efficacy (r\u00a0=\u00a00.57, p\u00a0<\u00a00.001) and negatively associated with maternal anxiety (r\u00a0=\u00a0-0.18, p\u00a0<\u00a00.001). Anxiety was inversely related to self-efficacy (r\u00a0=\u00a0-0.31, p\u00a0<\u00a00.001). Mediation analysis revealed that maternal anxiety partially mediated the relationship between SIDS awareness and parenting self-efficacy. Nurse-led care should combine safe sleep education with routine screening and management of maternal anxiety. Reassurance-focused communication and brief psychosocial support during postnatal visits may strengthen maternal confidence and improve adherence to safe infant care practices. Maternal anxiety partially shapes how SIDS awareness influences parenting self-efficacy. Integrating emotional support with SIDS education may strengthen maternal confidence and improve safe infant care practices.",

ARX encodes a transcription factor critical for GABAergic neuron development and functioning, regulating the expression of key neurodevelopmental target genes. Variants in ARX result in a wide clinical spectrum, ranging from asymptomatic female carriers to severe developmental syndromes in both sexes. This study investigates the functional impact of 16 ARX variants, including known pathogenic, likely pathogenic, and novel de novo variants, some associated with atypical presentations such as sudden infant death. Using transient expression in N2a neuroblastoma cells, we employed a comprehensive functional approach-including luciferase reporter assays, Western blotting, immunofluorescence, and RT-qPCR-to assess protein expression levels, subcellular localization, their interaction with known corepressors (TLE1 and CtBP1), and their transcriptional activity on selected ARX-known targets. Our results demonstrate that all tested variants disrupt normal ARX transcriptional function, with several also altering protein localization or expression. Remarkably, a subset of variants exhibited dominant-negative effects, offering a compelling explanation for unexpectedly severe phenotypes in female patients, likely exacerbated by skewed X-inactivation and other modifying factors. By integrating experimental data with a literature-based review of published ARX variants, we provide refined genotype-phenotype correlations, highlighting the importance of mutation type, positional context within key ARX functional domains, and patient sex. Altogether, this study advances our understanding of the molecular mechanisms driving ARX-related NDDs, emphasizing the importance of functional testing for accurate variant interpretation and paving the way toward informed genetic counseling and potential therapeutic development.",

Therefore, this study aimed to assess the pooled incidence of infant mortality and its associated factors in LMICs. We used clustered data extracted from the recent Demographic and Health Surveys (DHS 2018-DHS 2024) of all LMICs. A total of 1,404,826weighted numbers of recent live births were included in the study. A lognormal shared gamma frailty model was employed. We used the Akaike information criterion (AIC), Bayesian information criterion (BIC), and log-likelihood values for model comparison. An adjusted time ratio ([Formula: see text]) with a 95% confidence interval (CI) in the final model was used to select variables that had a significant association with time to infant death. The data were analyzed via R software version 4.3.1. A total of 1,404,826 live births were included in the final analysis. By the end of the follow-up period, 72,569 infants (5.17%, 95% CI: 5.13-5.21) had died before their first birthday. The pooled estimate of the IMR in LMICs was 39 per 1000 live births (95% CI: 32.68-44.95). Maternal education, family size\u2009\u2265\u20095, being a multiparous mother, being delivered at health facilities, being a female infant, immediate initiation of breast feeding, living in Europe & Central Asia, and living in West & East Asia were significantly associated with a lower risk of infant death. Conversely, maternal age 25-34, maternal age 35-49, unimproved toilet facilities, poor and middle wealth indices, maternal age at birth \u226419, birth interval of <18 and 18-23 months, multiple births, 2nd birth order, small birth size, low and medium Human Development Index (HDI), low and medium literacy rate, low-income and lower-middle income countries, rural residence, living in West Africa, South & Central Africa, and South Asia were significantly associated with a higher risk of infant mortality. The infant mortality rate (IMR) in LMICs remains high compared with that in WHO targets and shows significant regional variation. West Africa and South Asia had the highest pooled estimate of infant deaths. Variables such as maternal age, education, wealth index, age at first birth, parity, family size, child sex, birth interval, multiple pregnancy, birth order number, perceived child size at birth, place of delivery, residence, country's literacy rate, income group, and HDI value were identified as significant predictors of time to infant death. Therefore, public health interventions that enhance health facility delivery, optimal birth spacing, maternal education, and immediate breastfeeding are crucial to reduce the incidence of infant mortality in LMICs.",
"42003135": "ID: 42003135\nTitle: A motor thalamic site in humans that suppresses involuntary breathing without awareness.\nAbstract: Breathing is generated by brainstem respiratory networks but can be controlled and modulated by forebrain activity. The recent clinical adoption of thalamic electrode implantation during intracranial electroencephalography (iEEG) provides a rare opportunity to examine the role of the human thalamus in respiratory control. Here, we tested whether thalamic stimulation alters breathing in 11 patients undergoing iEEG for epilepsy monitoring. Across 412 stimulation trials at 108 thalamic sites, thalamic stimulation induced central apnea in every participant. Apnea occurred in isolation without sensory or motor effects and without awareness of breathing cessation. Apnea occurred with stimulation of either the right or left thalamus and was observed across all ages, including participants as young as 22 mo. Volitional breathing and speech were preserved, indicating that respiratory motor pathways remained functional. In contrast, except for the amygdala, stimulation of other forebrain regions, including the hippocampus, insula, cingulate, and frontal, temporal, and parietal cortices, did not affect breathing. Respiratory inhibition depended on thalamic location, occurring most consistently with stimulation of the ventral lateral anterior (VLa) and ventral anterior (VA) nuclei. A machine learning algorithm localized the focal apneic region within the anterior motor thalamus, centered in VLa and extending into VA. Identification of a focal apneic site in the VLa/VA motor thalamus expands thalamic function, revealing a forebrain node capable of overriding brainstem respiratory control. This circuit may coordinate breathing with volitional behaviors such as speech, and dysfunction of this circuit may play a role in central apnea disorders, including sleep apnea, SUDEP, and SIDS.NEW & NOTEWORTHY This study identifies a focal site in the human motor thalamus where electrical stimulation suppresses involuntary, automatic breathing and induces apnea without awareness. Using intracranial recordings in pediatric and adult patients, we found that this effect localizes to the ventral anterior/ventral lateral anterior nuclei. These findings reveal a previously unrecognized thalamic function in the forebrain control of breathing.",

Despite global and national efforts to promote optimal breastfeeding, early initiation remains suboptimal in much of Sub-Saharan Africa. This study examined the prevalence and factors associated with delayed initiation of breastfeeding in Tanzania. We analyzed secondary data from the 2022 Tanzania Demographic and Health Survey and Malaria Indicator Survey, a nationally representative cross-sectional survey. The study population comprised children under 24 months. The outcome variable was delayed breastfeeding initiation, defined as not initiating breastfeeding within 1\u2009h of life. Weighted data were analyzed using multilevel mixed-effects logistic regression to identify associated factors. A total of 4478 children were included, with a mean (\u00b1SD) age of 11.5\u2009\u00b1\u20096.9 months. The prevalence of delayed initiation was 24.4%. Child-related factors included first (aPR\u2009=\u20091.32; 95% CI: 1.13-1.55) and second birth order (aPR\u2009=\u20091.21; 95% CI: 1.06-1.39). Maternal age 35-49 years was also associated (aPR\u2009=\u20091.16; 95% CI: 1.02-1.32). Health-related factors included absence of immediate skin-to-skin contact (aPR\u2009=\u20091.85; 95% CI: 1.64-2.09), cesarean delivery (aPR\u2009=\u20092.45; 95% CI: 2.17-2.78), lack of birth assistance (aPR\u2009=\u20091.63; 95% CI: 1.16-2.28), and assistance from non-skilled provider (aPR\u2009=\u20091.42; 95% CI: 1.09-1.84). Geographically, delayed initiation was more prevalent in Zanzibar (aPR\u2009=\u20091.62; 95% CI: 1.33-1.98) and less prevalent in the Southern zone (aPR\u2009=\u20090.54; 95% CI: 0.36-0.80). Nearly one in four newborns in Tanzania experience delayed breastfeeding initiation. Delayed initiation was associated with child, maternal, health-related, and geographical factors. Strengthening skin-to-skin contact, skilled birth attendance, cesarean support, counseling for first-time and older mothers, and addressing geographical disparities may improve early initiation and support progress toward Sustainable Development Goal target 3.2.",

Data on all infants (n = 1 546 787) born in Finland between 1991 and 2016 were collected from national registers. Of those born prematurely (5.9%), infants born MP and LP accounted for 85,9%. Early, late, and postneonatal mortality decreased with advancing gestational age. Despite overall declines, early neonatal mortality remained significantly greater in infants born MP and LP than in infants born at term. Over time, early neonatal mortality decreased only in MP and LP groups, whereas first-year mortality declined in infants born MP and LP. Predictors of death in all mortality categories in infants born MP and LP included small for gestational age, low Apgar score, and ventilator treatment. Some regional and hospital-level differences in early neonatal mortality were observed. Causes of death in infants born MP and LP resembled those of term more than infants born very preterm, with congenital anomalies being the most common, albeit not easily preventable causes of death. Infants born MP and LP had an elevated risk of early neonatal mortality compared with infants born at term. Continued reductions may be achieved by targeting preventable causes such as asphyxia and respiratory distress, while counseling-based interventions may help prevent sudden infant death syndrome and reduce late neonatal and postneonatal mortality.",

The mean age at death was 4.5\u00a0\u00b1\u00a04.9\u00a0months, 30 children were male (65%). The main PMFP features were retinal changes resembling central retinal artery occlusion and macular and/or peripheral white radial retinal folds. The presence of a macular fold was associated with a longer post-mortem interval (presence versus absence of a macular fold: 12.2\u00a0\u00b1\u00a07.2\u00a0h [range: 4-30] versus 4.5\u00a0\u00b1\u00a01.6\u00a0h [range: 3-9], p\u00a0<\u00a00.001).

Our research team set out to explore how a community-based and culturally informed perinatal support model could address the needs of Black mothers and their families. We developed and implemented the Today Not Tomorrow Pregnancy and Infant Support Program (TNT-PISP), a community-based, culturally informed perinatal support model integrated with traditional obstetrical care. From October 2019 to August 2022, we held monthly support group sessions facilitated by Black community-based doulas, Black physicians, and community partners. Twenty-five participants engaged in topic-focused and freeform sessions to discuss mental health, breastfeeding, peripartum care, and medical racism. Data were collected through semi-structured interviews and focus groups and analyzed using the Daughtering Method and reflexive thematic analysis. Participants emphasized the importance of shared Black identity and culture in fostering connection and trust. The group's open, judgment-free environment allowed for meaningful conversations and emotional support. Participants valued the exchange of parenting knowledge and community resources. The program's flexible structure and child-friendly setting were key strengths, enabling consistent participation despite busy schedules. This study highlights the potential of community-based, culturally informed perinatal support programs to promote health equity for Black women and infants.

The identification of the most prevalent causes of death in this population will allow further targeted advancements in healthcare. The aim of this study was to analyze the causes of infant deaths between 1998 and 2024 in the Poznan Metropolitan area. The analysis was performed based on autopsy reports conducted between 1998 and 2024 by the Department of Forensic Medicine of Poznan University of Medical Sciences. The criterion for including the case in the study was death during the first year of life. A total of 155 protocols met the criteria and were included in the study. No downward trend over the years was observed. The first month of life was found to have the highest mortality rate (38.7%).

Mortality also varied across racial and ethnic groups, with higher rates among infants born to non-Hispanic Black mothers. Birth-related characteristics showed similar patterns, with higher rates among infants with low birth weight and earlier gestational age. This study highlights persistent disparities in SUID across maternal demographic and birth-related characteristics in the United States. Continued public health efforts focused on safe sleep education, maternal health, and targeted prevention strategies may help address these disparities.",

However, qualitative explorations are lacking, especially within culturally diverse settings. This study aims to explore the beliefs on the mechanisms of the relationship between diet, food systems, and mental health, and the lived experience of such, through a case study of one Caribbean Small Island Developing State, to inform culturally grounded public health strategies that integrate nutritional and psychological well-being. Fifteen interviews with food system stakeholders and five focus groups with the general public were conducted. Transcripts were analyzed using a grounded theory approach with a critical realist epistemological stance. Four major categories centered on beliefs of mechanistic effects of diet on mental health, as well as broader perspectives of the relationship between food systems, food experiences, and mental health. Participants believed that (1) unhealthy diets of processed and chemically treated foods contribute to poor mental health and that (2) food insecurity is a key threat to mental health, but they also believed that (3) consumption of locally produced foods and (4) residing in agricultural communities can be beneficial to mental health. Participants recognize that diet influences mental health through physiological, social, and structural pathways, but this connection is threatened by rising dependence on imported, processed foods. Along with complementary quantitative research, the findings highlight the potential of expanding nutritional health literacy and clinical guidance and strengthening local food systems and traditional diets for mental well-being among Caribbean Small Island Developing States.",

Children deceased from SUDI and registered in the French SUDI registry from 2015 to 2024 were included retrospectively. The postmortem investigations performed in SUDI cases were described, their temporal trends since 2015 and their compliance with the French National Health Authority guidelines were assessed. The minimum set of non-invasive postmortem investigations performed in cases required to detect unnatural death, including fundus examinations, imaging and toxicological tests, was studied. We examined 1 934 SUDI cases. Laboratory tests were the most frequently performed procedures (93.0%), and fundus examinations were the least frequent (21.6%). There was a significant increase in fundus examinations (9.3% to 31.6%), laboratory tests (87.6% to 97.3%), bacteriological tests (91.4% to 97.2%), toxicological tests (79.0% to 91.0%), and whole-body imaging (75.2% to 87.3%) from 2015 to 2024. Only 2.1% of cases were investigated strictly according to the French guidelines. We found that 13.2% of cases underwent minimal non-invasive postmortem investigation for detecting unnatural death. Although certain investigations are performed more frequently, efforts to improve local protocols and updated guidelines are needed to ensure thorough postmortem investigations, resulting in an improved diagnostic approach.",

Machine learning (ML) has shown excellent performance in healthcare prediction tasks due to its capability of efficiently handling interactions within mixed-type tabular data. Therefore, this study aimed to develop an interpretable model that can predict neonatal death based on the Ethiopian Demographic Health Survey (EDHS) dataset. This study utilized the imbalanced EDHS dataset collected from all surveys conducted in 2000, 2005, 2011, 2016, and 2019. We evaluated some basic and tree-based ensemble ML algorithms validated with five-fold cross-validation and 80/20 data splitting. Unbalanced, weighted, and SMOTENC class balancing techniques are utilized across both evaluation strategies. The models were compared based on sensitivity and SHAP interpretability with consideration of F1-score and AUC-PR trade-offs. The weighted LightGBM model achieved the highest recall performance (recall\u2009=\u200987.2%) with a slight reduction of F1\u2009=\u200985.3% and PR-AUC\u2009=\u200992.6% by preserving SHAP interpretability. The SHAP analyses indicate that breastfeeding initiation, number of living children, and ANC visits are the top three key predictors. The dependence plot shows positive SHAP values for delayed breastfeeding initiation, no living children, no antenatal care, lower household member size, grand multiparity, male sex, small birth size, twin births, and short preceding birth intervals. The weighted LightGBM model not only had better sensitivity with competitive AUC-PR results but also showed reliable interpretability using SHAP analyses. The model predicted strong neonatal mortality odds associated with delayed breastfeeding initiation, absence of living children, and lack of antenatal care visits. The model also predicted that neonatal mortality would be more likely for low household member size, grand multiparity, male sex, small birth size, twin births, and short preceding birth intervals. Finally, adequate ANC visits and early initiation of breastfeeding were protective and affected survival outcomes for neonates, emphasizing the importance of maternal and newborn healthcare programs.",

In abusive head trauma (AHT), biomechanical models help clarify injury mechanisms, particularly the role of sagittal angular acceleration in younger infants. However, challenges remain, such as detecting subtle brainstem pathology with neuroimaging, stressing the need for prospective clinicopathological correlation. Meanwhile, understanding of chronic traumatic encephalopathy (CTE) is expanding beyond contact sports to include victims of intimate partner violence. Research on sudden unexpected death in epilepsy (SUDEP) indicates overlaps with sudden infant death syndrome (SIDS) and identifies key risk factors. At the same time, forensic neuropathology's primary role remains the exclusion of other causes of death. Artificial intelligence shows promise for analyzing radiological and histopathological data in traumatic brain injury (TBI) and epilepsy, though its adoption for routine purposes remains a distant goal. Further developments include a better understanding of the cerebellum's vulnerability to TBI, standardized postmortem MRI protocols, and the use of cerebrospinal fluid biomarkers, such as GFAP and S100B, to estimate time of death. Finally, research continues to probe the complex links between brain morphology and behavior, and recent studies of the neuropathology of alcohol use disorder have revealed microglial changes rather than overt neuronal loss.",
"42185501": "ID: 42185501\nTitle: Continuous and prolonged breastfeeding in wild Bornean orangutans verified with fecal proteomics.\nAbstract: Orangutans have a slow life history with one of the longest interbirth intervals and the lowest reported infant mortality rates among primates or even mammals. Breastfeeding is a key factor in their life history because it possibly promotes offspring health and increases maternal interbirth intervals. However, quantifying milk intake is difficult, and existing estimates for their weaning age are contradictory. Here, we use fecal proteomics to predict the breastfeeding and weaning patterns in wild Bornean orangutans in Danum Valley, Sabah, Malaysia. Age changes in milk-specific proteins identified from 20 feces of five immature individuals revealed that the orangutans in Danum Valley consistently consumed milk for \u22656.5 years after birth, consistent with the behavioral evidence as having one of the longest breastfeeding periods in mammals. Milk intake was significantly correlated with higher levels of biological defense and probiotic bacterial proteins. Mothers were not pregnant with their next offspring during the breastfeeding period. These results indicate that a continuous and long breastfeeding period is a key component of the slow life history of orangutans and shows that fecal proteomics can be applied to a wide range of wild animal populations, with the potentials to uncover novel aspects of behavior and physiology.",

During the pandemic period, an increase in the incidence of Sudden Unexpected Infant Death (SUID) and Sudden Infant Death Syndrome (SIDS) was observed. Currently, their rates remain elevated compared to the prepandemic period. The pathogenetic mechanisms underlying the fulminant course of infection in infants leading to fatal outcomes remain insufficiently understood. In this study, we report for the first time the results of histological and immunohistochemical examination of the lungs in a case of COVID-19-associated SUID in a 2-month-old infant. The absence of similar studies in the available literature limits opportunities for analyzing the pathogenesis of SUID. Our data allow a detailed characterization of the histological changes in the lungs, the localization and range of SARS-CoV-2 nucleocapsid protein expression, the identification of molecular mechanisms underlying apoptosis in the pulmonary microvascular endothelium, and the elucidation of the role of endothelial dysfunction. Particular attention in this article is devoted to the role of cytokines (IL-6, TNF-\u03b1, and IFN-\u03b3) in the pathogenesis of hyperacute viral infection. The obtained data demonstrate substantial differences between the observed changes and the classic presentation of COVID-19 in older children. These findings offer prospects for improving prevention strategies and developing targeted therapy for fulminant forms of COVID-19, while also contributing to the understanding of SIDS pathogenesis.",

Understanding both the determinants and the spatial distribution of infant deaths is essential for designing targeted interventions and reducing persistent inequalities. We analysed nationally representative data from multiple rounds of the Ghana Demographic and Health Surveys, comprising 19\u2009558 infant survivors and 3464 infant deaths. Local Indicators of Spatial Association and kernel density estimation were applied to produce cluster and spatial risk maps, respectively. A shared frailty Cox proportional hazards model, accounting for unobserved heterogeneity at the regional level, was used to estimate adjusted HRs. Infant mortality exhibited significant spatial autocorrelation, while regional quantile maps revealed distinct yet overlapping geographic patterns for both neonatal and infant mortality. Infant mortality showed substantial clustering. Elevated risks were observed in Upper West, parts of Savannah and Ashanti, whereas lower risks were evident in Greater Accra, North East and Eastern regions. Factors associated with lower hazards included tertiary maternal education (adjusted HR (aHR)=0.66; 95%\u2009CI 0.48 to 0.89), health insurance coverage (aHR=0.86; 95%\u2009CI 0.80 to 0.94), early initiation of antenatal care (aHR=0.88; 95%\u2009CI 0.83 to 0.93) and completion of \u22654 antenatal visits (aHR=0.90; 95%\u2009CI 0.82 to 0.98). Socioeconomic gradients were apparent, with infants in relatively richer households experiencing lower mortality hazards. Infant-level characteristics strongly predicted survival, including normal birth weight (aHR=0.60; 95%\u2009CI 0.45 to 0.75), breastfeeding (aHR=0.39; 95%\u2009CI 0.31 to 0.47), longer birth intervals (aHR=0.63; 95%\u2009CI 0.57 to 0.70) and vaccination (aHR=0.42; 95%\u2009CI 0.32 to 0.53). Infant mortality in Ghana displays marked spatial heterogeneity and regional-level effects. Strengthening maternal and newborn services in hot-spot regions, expanding early antenatal and postnatal care and targeting high-risk maternal profiles may accelerate progress toward equitable child survival.",

A process-level understanding of how integrated organic and mineral fertilization interacts with genotype to control yield formation, grain nitrogen (N) partitioning, and nitrogen use efficiency (NUE) in coarse-textured soils remains limited. Here, we quantified the combined effects of NPK fertilization regime (100% soil application vs. increasing proportions of fertigation), compost rates, and wheat (Triticum aestivum L.) genotype on yield, yield components, grain quality, and NUE in a low-fertility sandy soil over two growing seasons in an arid environment. We hypothesized that increasing fertigation would additively enhance yield components and NUE with compost, with diminishing returns at high compost rates, and that genotypes would differ in the relationship between grain yield and grain protein concentration. A split-split plot design included three cultivars (Sakha-95, Sids-14, Misr-1), four NPK regimes (F1: 100% soil; F2-F4: 50-100% fertigation), and three compost rates (12, 24, and 36 t ha\u207b\u00b9). Full fertigation (F4) increased grain yield and NUE by 49.8% relative to 100% soil application, primarily by increasing spike density, grains spike\u207b\u00b9 and 1000-grain weight. Compost further enhanced yield and NUE, with 36 t ha\u207b\u00b9 giving 18% higher grain yield than 12 t ha\u207b\u00b9. Genotypes differed markedly: Sakha-95 achieved the highest grain and biological yields and NUE, whereas Sids-14 and Misr-1 produced higher grain protein. Path analysis showed that spikes m\u207b\u00b2, 1000-grain weight, and fertile spikelets spike\u207b\u00b9 had the largest direct effects on grain yield, while principal component analysis revealed that combinations of high fertigation and high compost clustered with superior trait profiles. Intensive fertigation led to diminishing returns from compost at high rates, indicating an optimum organic input under high soluble nutrient supply. Together, these results provide trait-based insights into how integrated organic-mineral fertilization and genotype control yield formation and N recovery in sandy, low-fertility soils. The findings are relevant to irrigated field-crop systems on light-textured soils across arid and semi-arid regions where fertigation and organic amendments are increasingly used to improve NUE and sustainability.",

To examine sociodemographic, maternal health, and healthcare utilization factors associated with low birth weight in Ghana. This cross-sectional study analyzed data from 8,581 women 15-49 years from the 2022 Ghana Demographic and Health Survey (DHS). LBW was defined as birth weight <\u20092,500 grams. Logistic regression models were used to identify predictors of LBW. Crude and adjusted odds ratios with 95% confidence intervals were calculated. The prevalence of LBW was 16.8%. The independent predictors of LBW included household poverty (aOR = 1.66), middle-income status (aOR = 1.49), lack of malaria prevention (aOR = 2.77), absence of skilled antenatal care (aOR = 1.71), and lack of iron supplementation (aOR = 1.31). Protective factors were maternal secondary education (aOR = 0.68), advanced maternal age (aOR = 0.74), and overweight BMI (aOR = 0.56). Significant interactions were identified between young maternal age and underweight status (aOR = 2.89). Also, there was an interaction between poverty and lack of malaria prevention (aOR = 0.42). Low birth weight in Ghana is influenced by socioeconomic inequalities, maternal nutritional status, and healthcare access, with synergistic effects between young maternal age and undernutrition. Targeted interventions addressing poverty, maternal nutrition, and ensuring access to skilled antenatal care, iron supplementation, and malaria prevention are essential for reducing LBW prevalence.",

This is a nested case-control study within a prospective cohort of N\u2009=\u2009606 adult birthing people who delivered at a single academic medical center between 2011 and 2022. The outcome of interest was knowledge of the AAP infant safe sleep recommendations which was determined by participants demonstrating knowledge of five factors. We separated data according to the bimodal distribution of responses: 2011-2014 and 2019-2022. We used Chi square analysis to evaluate change in demonstrated knowledge of AAP guidelines over time for each race. We utilized binomial logistic regression modeling to determine crude odds ratios and calculated 95% confidence intervals to quantify the relationship between the outcome and demographic variables. We found both the non-Hispanic Black and non-Hispanic White groups significantly increased demonstrated knowledge of AAP recommendations over time (p\u2009=\u2009.01 and p\u2009<\u2009.01 respectively). In the pre-intervention period, non-Hispanic Black birthing people were significantly less likely to demonstrate knowledge than non-Hispanic White birthing people (OR 0.52 95% CI [0.31-0.85]). In the post-intervention period, there was no significant difference in demonstrated knowledge between non-Hispanic Black and non-Hispanic White birthing people (OR 0.36 95% CI [0.13-1.03]). Our results provide insight into the potential impact of robust infant mortality public health initiatives on the awareness of safe sleep recommendations in birthing people within Hamilton County, Ohio.",
"42279599": "ID: 42279599\nTitle: Hidden and Under-Recognized Causes of Sudden Unexpected Death in Infancy (SUDI): A Comprehensive Review of Autopsy Findings.\nAbstract: Sudden unexpected death in infancy (SUDI) remains a major challenge in pediatric pathology and forensic medicine. Despite advances in diagnostic techniques, many cases are still classified as unexplained and labeled as sudden infant death syndrome (SIDS). Increasing evidence suggests that a proportion of these deaths may be due to \"hidden\" causes not detectable through routine post-mortem examination. A narrative review of the literature (2000-2026) was conducted using PubMed and Scopus, focusing on under-recognized causes of SUDI and their diagnostic implications. Relevant studies were selected and organized into major pathological and forensic categories. Hidden causes of SUDI include a wide spectrum of conditions. Cardiac disorders-such as myocarditis, cardiomyopathies, and inherited arrhythmogenic syndromes-are frequently implicated and may require molecular autopsy for detection. Infectious diseases, often presenting with minimal or nonspecific findings, represent another important category, particularly viral and bacterial infections. Inborn errors of metabolism, especially fatty acid oxidation defects, may lead to sudden death in the absence of specific autopsy findings, highlighting the role of biochemical analyses. Neuropathological abnormalities involving brainstem regulatory systems may contribute to impaired autonomic control. Environmental, toxicological, and medico-legal factors-including unsafe sleep conditions, toxic exposures, and inflicted injury-must also be considered. SUDI is a multifactorial entity in which many unexplained deaths may be attributable to identifiable but overlooked conditions. A standardized, multidisciplinary approach integrating autopsy, ancillary investigations, and molecular diagnostics is essential to improve diagnostic accuracy and support prevention strategies.",

Pediatric basic life support.\nAbstract: Pediatric cardiac arrest primarily arises from asphyxia in infants and trauma in older children, contrasting with adult etiologies dominated by cardiac events. This underscores prevention as the cornerstone of pediatric basic life support, through injury mitigation like child restraint systems and water supervision, safe sleep practices including supine positioning on firm surfaces with caregiver smoking cessation to reduce sudden infant death syndrome, plus awareness of child abuse and adolescent suicide prevention. In hospitals, pediatric early warning systems (PEWS) enable early deterioration detection via vital sign scoring for timely intervention. Major updates in the 2025 pediatric basic life support guidelines reflect evidence-driven refinements. First, hospitals should implement PEWS to prompt rapid response teams for at-risk inpatients. Second, all rescuers (lay and healthcare providers) should employ the two-thumb encircling hands technique for infant chest compressions for optimal depth (about 4 cm), rate (100-120/min), and recoil; one-hand heel compression serves as backup if infeasible. Third, lay rescuers may apply automated external defibrillators for nontraumatic out-of-hospital cardiac arrest in children aged 1 year or older, prioritizing prompt attachment after initial cardiopulmonary resuscitation (CPR) cycles to address potential shockable rhythms. Fourth, for infant foreign body airway obstruction, alternate five back blows (over the spine between scapulae) with five chest thrusts (using heel-of-hand on sternum) until cleared or unresponsive, then transition to CPR. These updates aim to enhance bystander intervention, CPR quality, and survival with favorable neurologic outcomes in pediatric cardiac arrest.",

The neurobiological mechanisms involved remain unclear. We investigated the role of wake-promoting Orexin (Ox) and Histamine (HA) neurons in SIDS. Cerebrospinal fluid (CSF) Ox levels were measured in 61 living controls and 70 Sudden Unexpected Death Infants (SUDI: 38 SIDS, 32 explained deaths (ED)). HA and tele-methylhistamine (t-MeHA) were analyzed in an additional 46 SUDI (34 SIDS, 12 ED) and 42 controls. Immunohistochemistry was performed on hypothalamic tissue from 11 SIDS and 8 ED cases to quantify Ox and HA neuron numbers. CSF Ox levels did not differ overall between groups but were higher in SUDI infants aged 2-6 months. HA and t-MeHA levels were elevated in SUDI, likely reflecting postmortem release. Ox neuron numbers were increased in rostral hypothalamic region in SIDS compared with EDs, whereas HA neuron numbers were unchanged. SIDS is associated with increased Ox neuronal activity during the peak risk period, possibly reflecting a homeostatic upregulation in response to arousal deficit or repeated stress or hypoxia, while the role\u00a0of\u00a0HA system remains to be clarified with more sensitive biomarkers. First study evaluating orexin and histamine systems in SIDS using CSF and postmortem brain tissue. Identifies elevated orexin activity in SIDS infants, particularly in the 2-6 month risk window. No evidence to date for direct histamine involvement; need for more sensitive biomarkers. Suggests orexin system as a potential biomarker for SIDS risk stratification.

The search was conducted using the Virtual Health Library and PubMed databases, with the descriptors \"gut microbiota\" combined with \"breastfeeding\" (BF) and \"infant formula.\" After screening, 18 articles were selected for final analysis. Findings indicate that cesarean section reduces initial gut microbial diversity by 30%-50% and decreases Bifidobacterium colonization, while increasing the abundance of Enterobacteriaceae and Clostridium. In contrast, exclusive BF supports a more favorable microbial profile, enriched in bifidobacteria, and contributes to immune system maturation. The literature also highlights the importance of other genera, including Lactobacillus, Veillonella, and Firmicutes, in regulating inflammation, producing short-chain fatty acids, and protecting against pathogens. Supporting vaginal birth and exclusive BF emerges as a key strategy to promote a more resilient and health-promoting gut microbiota during infancy.",

We explored whether cortical thickness in occipital and parietal regions predicted global motion processing in 7-year-old children born very preterm. Structural magnetic resonance imaging (MRI) measures were successfully computed for 99 children, motion coherence thresholds were evaluated in 85 participants and functional MRI blood oxygen level-dependent (BOLD) percent signal change in the primary visual cortex (V1) and/or middle temporal area (V5) was quantifiable in 23 participants. Parietal cortical thickness predicted V5 BOLD response to 100% coherent motion stimuli, where individuals with thinner parietal cortices had stronger V5 BOLD responses to coherent motion. These findings indicate that parietal thickness may serve as a structural indicator of dorsal stream development in children born very preterm and provide a structural basis for understanding individual differences in global motion processing.",

Although Kcna2 knockout mice exhibit epilepsy, the pathogenic mechanisms underlying GoF and mixed-type variants remain poorly understood. This study compared GoF and mixed-type models to investigate their underlying molecular mechanisms. CRISPR-edited heterozygous mice carrying R297Q or L290R variants were generated. Seizure activity was monitored and characterized using simultaneous video-EEG-ECG recordings. Cortical single-cell transcriptomic analysis was performed to demonstrate pathogenic mechanisms and associated regulatory pathways. R297Q and L290R heterozygous mice developed spontaneous lethal seizures within 1-2\u00a0months, with median survival times of 52 and 49\u00a0days, respectively. No overt motor deficits or brain malformations were observed. Video-EEG-ECG monitoring of R297Q mice revealed frequent Racine stage 2-3 seizures, with the most severely affected mouse exhibiting head nodding almost every minute, while stage 4-5 seizures were less common. All monitored mice eventually experienced lethal stage 5 seizures, characterized by postictal generalized EEG suppression followed by bradycardia and cardiac arrest, producing a terminal pattern that resembled human sudden unexpected death in epilepsy (SUDEP). Interictal ECG analysis demonstrated increased skipped beats and elevated heart rate variability, suggesting autonomic dysfunction. Single-cell transcriptomic analysis showed that R297Q selectively affected specific neuronal subtypes while L290R induced widespread changes, yet both variants converged on synaptic pathway disruption. In addition, enhanced NPY signaling was identified in both models, reflected in upregulation of Npy1r. GoF and mixed-type KCNA2 pathogenic variants converged on a seizure-induced premature death phenotype that recapitulated SUDEP and a shared cortical Npy-Npy1r signaling pathway. Enhanced Npy-Npy1r signaling may represent a potential therapeutic target for KCNA2-related epilepsies.",

It may be particularly important in global health research, where funding inequities and under-representation of local expertise in peer-reviewed research articles-often published by commercial publishers for substantial fees-can lead to evidence gaps in systematic reviews. However, searching, reporting and analysing grey literature poses conceptual and methodological challenges. We conducted a systematic scoping review of commercially published and grey literature examining food sources in Small Island Developing States (SIDS). The grey literature component aimed to expand understanding beyond built food environments and food retail and to promote epistemic justice by including traditionally excluded voices, knowledge and experiences. This might be especially important in SIDS, which, due to their small size, remote locations and limited global visibility, might not be well represented in commercially published literature. In this paper, we discuss how grey literature enriched our findings, offering detailed descriptions of diverse food sources, regional data and country comparisons less present in commercially published sources. These documents frequently reflected multisectoral initiatives and were developed through partnerships involving local stakeholders. Beyond highlighting the value of grey literature, we also provide practical guidance for its use in evidence synthesis. This includes key principles for effective searching and screening to support researchers aiming to incorporate grey literature in a systematic and transparent way. Our findings underline the importance of including grey literature to avoid excluding valuable perspectives and perpetuating structural imbalances in global health knowledge.",

However, the Halo Effect and environmental factors now complicate this dose-response relationship. Following PRISMA 2020 guidelines, this systematic review identified 20 observational studies (n = 21,780) via PubMed, Scopus, and Web of Science. Inclusion logic utilized the PICOS framework, specifically selecting human studies that reported quantitative water F- levels alongside environmental or dietary confounders. Quality was assessed via the Newcastle-Ottawa Scale. Synthesis revealed that in optimal fluoridated areas (0.7 mg/L), mild DF prevalence reached 15-20% in cohorts with high \"Halo Effect\" exposure (infant formula, processed beverages) a twofold increase over historical benchmarks. High altitude (>2000 m) and arid climates further exacerbated toxicity by altering renal clearance. These factors sustain systemic fluoride levels that inhibit protease activity (MMP-20/KLK4) and induce endoplasmic reticulum stress during enamel maturation, causing hypomineralization. Current water-centric monitoring is insufficient for modern risk assessment. A transition toward Total Daily Intake (TDI) models and context-specific standards accounting for altitude and dietary diffusion is essential to balance caries prevention with systemic safety.",

Donor human milk (DHM) is recommended when the mother's milk is unavailable, but the optimal initiation timing is unclear. This study evaluated the association between DHM initiation timing and outcomes in very-low-birth-weight (VLBW) infants in Japan. Methods: This multicenter retrospective cohort study used data from a national human milk bank registry (2018-2023) and the Neonatal Research Network of Japan (NRNJ; 2022). Infants with birth weight <1500 g were categorized by DHM initiation timing (\u226424, 25-48, or >48 h), with infants in the NRNJ cohort serving as the comparison group. The primary outcome observed was NEC incidence, including all stages; secondary outcomes included in-hospital mortality and time to full enteral feeding. Bayesian regression models were applied. Detailed feeding data were unavailable in the NRNJ cohort. Results: Among 2962 infants, NEC incidence was low across groups. NEC occurred in 1.31% of the \u226424 h DHM group and 1.83% of the NRNJ group, with mortality rates of 4.53% and 6.23%, respectively. Although NEC incidence was numerically lower in the \u226424 h DHM group, estimates were imprecise because of limited events. Early DHM initiation was associated with lower in-hospital mortality and earlier full enteral feeding, particularly in infants with <1000 g birth weight. Conclusions: Early DHM initiation was associated with lower mortality and earlier achievement of full enteral feeding in VLBW infants without elevated NEC risk. However, because detailed feeding information was unavailable in the comparison cohort, these associations should be interpreted cautiously. Given the observational design and heterogeneous nutritional exposures, further prospective studies are warranted.",

It is increasingly used in gut physiology research, yet its application to nutrient absorption remains underexplored. Four media types were assessed for their ability to support IPEC-J2 barrier maturation and permeability: Dulbecco's modified Eagle medium/Ham's F-12 with 10% fetal bovine serum (FBS10), 10% porcine serum (PS10), 5% porcine serum (PS5) supplemented with Wnt3a-R-spondin-Noggin conditioned medium (PS5+L-WRN), and PS5 with epidermal growth factor and insulin-transferrin-selenium (PS5+EGF+ITS). Culture medium influenced epithelial phenotype, with more than a 30-fold range in transepithelial electrical resistance (TEER), which plateaued by day 12. PS10 supported a balanced profile, characterized by intermediate TEER (2395.00\u00a0\u00b1\u00a0485.51\u00a0\u03a9\u00a0\u00d7\u00a0cm2), lowest lactulose and mannitol permeability (p\u00a0<\u00a00.05), high lactate dehydrogenase activity (p\u00a0<\u00a00.05\u00a0vs. PS5+L-WRN and FBS10), enhanced membrane localization of tight junction proteins (p\u00a0<\u00a00.05\u00a0vs. PS5+EGF+ITS), and reduced fibroblast marker S100A4 (p\u00a0<\u00a00.05\u00a0vs. PS5+EGF+ITS). Treatment with digested infant milk formula did not compromise barrier integrity in PS10-cultured IPEC-J2 monolayers and enabled transport of free amino acids to the basolateral compartment. These findings support IPEC-J2 as an alternative to Caco-2 cells for applications in infant nutrition research in vitro.",

Specialized preprocessing pipelines have been developed to address these issues, but no structured cross-pipeline evaluation of their capabilities currently exists. This article presents a capability framework for ten prominent infant EEG preprocessing tools - nine infant-specific tools (APICE, Adjusted-ADJUST, GADS, NEAR, HAPPE, HAPPE+ER, HAPPILEE, BEAPP, and MADE) and the Modular pipeline, a general-purpose approach scalable to infant data - organized around five capability dimensions: artifact handling, automation and scalability, flexibility and adaptability, developmental sensitivity, and validation against empirical data. The framework is proposed as an exploratory evaluative heuristic, not a definitive taxonomy. For each dimension, each pipeline was assigned a maturity level from 1 (minimal documented support) to 5 (fully demonstrated, well-documented, and developmentally appropriate support), based on predefined anchored descriptors applied independently by two raters (overall Krippendorff's \u03b1 =.69), with lower agreement on the Automation and Validation dimensions - a pattern consistent with field-level ambiguity about what constitutes strong performance on these dimensions. No single pipeline reached the highest maturity level across all five dimensions; each occupies a distinct profile aligned with particular research needs. Notably, no pipeline achieved level 5 on either developmental sensitivity or validation against empirical data, indicating a field-wide gap in developmental calibration and cross-dataset validation. This capability framework provides a structured foundation for researchers and clinicians to make informed, context-sensitive preprocessing decisions in infant EEG studies.",

Although the gut is underdeveloped, optimizing administration of nutrition via the enteral route has been linked to improved long term outcomes, particularly when mother's own milk is prioritized as the initial source of nutrition. The goal of this review was to synthesize current evidence on best enteral nutrition practices for very preterm infants focusing on strategies that optimize long term neurodevelopment and infant health outcomes. This review examines the physiological importance of early enteral nutrition to support growth and neurodevelopment of very preterm infants. Clinical outcomes data related to different types of enteral nutrition sources are reviewed, as well as evidence-based practices regarding initiation of enteral nutrition, advancement, supplementation and fortification. Additionally, limitations in the existing literature are identified to inform future research directions. The collective evidence reviewed in this manuscript supports early, consistent, and human milk-based enteral nutrition as a central modifiable factor to improve growth, brain development, and long-term neurodevelopmental outcomes. While there are remaining uncertainties regarding the ideal timing for initiation, specific advancement strategies, and fortification methods, the available data supports the following: minimizing enteral fasting, prioritizing mother's own milk, and using protocolized feeding guidelines.",
"42363351": "ID: 42363351\nTitle: Exploring the association between breastfeeding and the risk of developing autism spectrum disorders.\nAbstract: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with rising prevalence globally, including Pakistan. While genetic factors substantially contribute to ASD risk, environmental and early-life nutritional factors are also being investigated. One such factor is infant feeding practices specifically breastfeeding, its duration and exclusivity. Human breast milk provides comprehensive protection via providing essential nutrients with immune defence and neurobiological regulation supporting optimal brain development. Despite these benefits, breastfeeding rates in Pakistan remain low. This mini-review explores the existing literature on the potential link between breastfeeding and ASD with a focus on epidemiological evidence and underlying biological mechanisms. While some studies suggest that breastfeeding may reduce the risk of ASD, the evidence is inconclusive due to methodological differences, recall bias, and cultural factors. Data from low- and middle-income countries is lacking and call for an urgent need for robust longitudinal research in Pakistan to better study this association and guide costeffective public health strategies.",

While the latter has been linked to immune maturation in term-born neonates, its impact on preterm immune development remains unclear. The aim of this prospective observational study was to investigate the effect of early antibiotic exposure on vaccine titers at a corrected age of four months. To achieve this, blood and stool samples were analyzed from 69 preterm infants (<32 weeks gestational age; 35 with 34 without antibiotic exposure during the first postnatal week) at postnatal day 14 and again at four months corrected age. We assessed vaccine-induced antibody titers against Bordetella pertussis and Haemophilus influenzae, immune cell profiles (flow cytometry), gut microbiome composition (16S rRNA sequencing), and plasma amino acid and acylcarnitine levels (tandem mass spectrometry). Preterm infants exposed to early antibiotics showed reduced antibody titers following vaccination, with differences appearing more pronounced in girls. Antibiotic-exposed girls displayed increased monocytes and myeloid-derived suppressor cells (MDSCs), both of which inversely correlated with antibody titers. Early antibiotic exposure was associated with differences in microbial community types at postnatal day 14, with Klebsiella-dominated and Bifidobacteria-lacking communities occurring more frequently in antibiotic-exposed infants. Antibiotic-exposed girls exhibited distinct metabolomic alterations, including elevated levels of two unsaturated fatty acids that negatively correlated with monocyte and MDSC abundance. Our findings suggest that early antibiotic exposure impairs vaccine responses in preterm infants and indicates a potentially sex-specific susceptibility. Antibiotic-driven changes in the microbiome and metabolome may sustain suppressive innate immune cell populations, which may in turn weaken adaptive responses to vaccination.",
"42368283": "ID: 42368283\nTitle: What's that noise-tackling sound pollution in the NICU: a systematic review.\nAbstract: Preterm infants are highly susceptible to environmental influences due to the immaturity of their sensory and neurological systems. In neonatal intensive care units (NICUs), ambient noise frequently exceeds recommended thresholds and may interfere with auditory and neurodevelopmental maturation. During a critical period of sensory refinement, infants are exposed to unpredictable, high-intensity soundscapes generated by alarms, respiratory devices, and staff activity, contrasting sharply with the regulated acoustic environment of the womb. This systematic review aimed to identify, describe, and categorize noise sources in the NICU and to examine their potential impact on preterm infants. A systematic search across six major databases [MEDLINE, Embase, APA Psychinfo, CINHAL, Scopus, Web of Science (WOS); 2000-2026] identified studies reporting 24-h noise levels, day-night variation, and differences between incubator-internal and external sound. Eligible studies were synthesized and visualized using forest, strip, and dot plots, interpreted relative to American Academy of Pediatrics (AAP) recommendations. From 113 included studies, most reported sound levels substantially above recommended limits. Alarms, staff conversations, and incubator-associated equipment were consistently identified as major contributors. Respiratory support devices produced the highest internal noise levels, at times exceeding overall NICU ambient noise. Interventions such as staff training, behavioral adjustments, and environmental modifications yielded short-term improvements but rarely produced sustained reductions. NICU noise is a modifiable risk factor with significant developmental implications. Future strategies should integrate environmental design, technological innovation, and infant-focused interventions at the incubator-device interface to create safer, developmentally supportive acoustic conditions. Evidence also suggests that excessive shielding may reduce meaningful auditory input, raising concerns about potential auditory deprivation.",

Here, we examined associations between neighborhood-level disadvantage, indexed by the Area Deprivation Index (ADI), and white matter myelination in infants and children aged 0-10 years (n = 61 MRI acquisitions across 43 children). Quantitative MRI-derived longitudinal relaxation rates (R1) are sensitive to myelin content and were used to assess white matter development. Higher ADI national percentiles (reflecting greater neighborhood disadvantage) were associated with lower R1 in several white matter regions, including the internal capsule, corona radiata, cingulate gyrus, fronto-occipital fasciculus, superior longitudinal fasciculus, and uncinate fasciculus. Whole-brain voxel-wise analyses further supported negative associations between ADI and myelination. These findings were stronger in the infant subsample and implicate white matter pathways supporting cognitive, socioemotional, and motor functions, suggesting that early environmental disadvantage may influence neurodevelopmental trajectories. Future work should examine which components of ADI drive these associations and how resilience may buffer the effects of disadvantage.",

To better understand early human islet cell development and maturation, we collected 123 pediatric pancreata and mapped morphological and spatiotemporal changes from birth through the first ten years of life. Using quantitative analyses and a combination of complementary tissue imaging approaches, including confocal microscopy and whole-slide multiplex imaging, we developed an integrated model for endocrine cell formation and islet architecture, including endocrine cell type heterogeneity and abundance, endocrine cell proliferation, and islet vascularization and innervation. We also assessed insulin and glucagon secretory profiles in isolated islet preparations from pediatric donors aged 2 months to 10 years and found a temporal difference in the maturation of insulin secretion compared to glucagon secretion. This comprehensive summary of postnatal and pediatric pancreatic islet development provides a framework for future studies and for integrating emerging genetic and genomic data related to islet biology and diabetes risk.",

An institution-based prospective follow-up study. The study was conducted in seven hospitals, comprising three general hospitals and four primary hospitals, between 14 February and 31 October 2025. The general hospitals, Injibara, Finote Selam and Pawi, provide level II neonatal intensive care services, whereas the primary hospitals, Dangila, Chagni, Jawi and Gimja Bet, provide level I newborn care services. These hospitals are situated in the Awi, West Gojjam and Metekel zones of the Amhara and Benishangul Gumuz regions in north-western Ethiopia. 955 LBW neonates were enrolled in the study. Neonates born outside health facilities were excluded if their birth weight was unknown, particularly those delivered by traditional birth attendants, as were neonates whose first recorded weight was obtained more than 24 hours after birth. Participants were selected using consecutive sampling and data were collected electronically using the KoboCollect mobile application. Data were analysed using R software V.4.4.3. Least Absolute Shrinkage and Selection Operator regression and multivariable logistic regression were used to identify predictors and develop a simplified risk score and nomogram. Model performance was evaluated in terms of discrimination and calibration, while internal validation was performed using bootstrapping. The clinical utility of the model was assessed using decision curve analysis (DCA). The final model included nine predictors: sepsis, perinatal asphyxia, respiratory distress syndrome, absence of exclusive breastfeeding, absence of Kangaroo Mother Care, gestational ages of 28 weeks to <32 weeks and 32 weeks to <37 weeks, and birth weights of <1000 g and 1000-1499 g. The original model demonstrated good discrimination, with an area under the curve of 84.2% (95% CI 81.5% to 86.9%). After internal validation, the simplified risk score and nomogram achieved areas under the curve of 83.85% and 83.5%, respectively. The model showed excellent calibration before and after validation. DCA indicated that the model provides meaningful clinical benefit. The nomogram and simplified risk score demonstrated excellent calibration and good discriminatory performance. Their application in clinical settings may improve early intervention and potentially reduce neonatal mortality in Ethiopia by enabling rapid, individualised mortality-risk prediction among LBW neonates. However, external validation in different settings is required.",
"42380651": "ID: 42380651\nTitle: Delayed maturation of the milk microbiome in women with type 1 diabetes.\nAbstract: The breastmilk microbiome plays a crucial role in gut microbial colonisation and immune development, but little is known about how it is influenced by type 1 diabetes. We conducted a longitudinal 16S rRNA gene sequencing study of milk from women with type 1 diabetes (n=69 pregnancies; 174 samples) and women who did not have type 1 diabetes (n=49 pregnancies; 123 samples), collected at seven timepoints from birth to 15 months postpartum. Alpha diversity (richness, inverse Simpson evenness) was analysed by generalised linear mixed models, beta diversity was analysed by Bray-Curtis dissimilarities and PERMANOVA, and differential abundance was analysed by limma. Additionally, we examined associations with maternal genetic risk score (GRS), maternal HLA type, glycaemic management (HbA1c) and breastmilk secretory IgA (sIgA), and performed a parallel analysis for the infant stool microbiome. A significant interaction between type 1 diabetes status and timepoint was observed for alpha diversity, both richness (p=0.01) and inverse Simpson diversity (p=0.003), indicating distinct temporal trajectories between women with and without type 1 diabetes. In those without type 1 diabetes, richness increased significantly between birth and 1\u00a0week postpartum, but this early increase was delayed in women with type 1 diabetes to between 1\u00a0week and 3\u00a0months postpartum (p=0.002). Beta diversity analysis revealed earlier and more extensive compositional shifts in women without type 1 diabetes compared to those with type 1 diabetes. These differences persisted after adjusting for Caesarean delivery, BMI, parity and infant sex, and were not attributable to a delay in initiating breastfeeding. Taxa with delayed enrichment in women with type 1 diabetes included Streptococcus spp. and Rothia mucilaginosa, which metabolise human milk oligosaccharides to short-chain fatty acids to promote development of the infant's gut barrier and immune system. Maternal GRS, HLA, HbA1c or sIgA were not associated with milk microbiota diversity trajectories. In infant stool samples, alpha diversity did not differ between exposure groups, and showed no evidence of delayed maturation. Beta diversity revealed an early compositional shift between birth and 1\u00a0week postpartum only in infants born to women without type 1 diabetes. Similarly, significant taxonomic changes between birth and 1\u00a0week postpartum were detected only in infants born to women without type 1 diabetes, but with some taxa differing between exposure groups at 1\u00a0week. Maternal type 1 diabetes is associated with delayed early maturation of the breastmilk microbiome. Early compositional differences in microbiota restructuring were also observed in the infant gut, partially mirroring the pattern in the milk microbiome; however, sustained differences in infant gut microbiota diversity were not detected. Further investigation could determine whether these changes affect development of the infant's gut and immune system.",
"42384215": "ID: 42384215\nTitle: Age and seasonality in Hirschsprung-associated enterocolitis risk: a longitudinal cohort study.\nAbstract: Hirschsprung-associated enterocolitis (HAEC) remains a major cause of morbidity, with poorly defined triggers and limited modifiable risk factors. Given the roles of immune immaturity and mucosal dysfunction in HAEC pathogenesis, this study evaluated whether age is associated with HAEC risk, and whether seasonal variation consistent with viral exposure is present. A retrospective cohort study was conducted including patients with HD treated at Children's Hospital Colorado (2008-2021). A piecewise exponential Poisson regression model estimated age-specific HAEC incidence rates, adjusting for Trisomy 21 and length of aganglionosis. Seasonal distribution was assessed using an exact binomial test comparing cold (October-March) versus warm months. Among 217 patients, 96 HAEC episodes were identified in 53 patients (24.4%). HAEC incidence was highest in the first year of life and declined progressively with age, with an 88% reduction in patients older than 36 months (RR 0.12, 95% CI 0.07-0.22, p\u2009<\u20090.001). Additionally, 60.4% of episodes occurred during cold months, exceeding expected distribution (p\u2009=\u20090.03). HAEC risk is strongly age-dependent, with a marked reduction after 36 months, supporting a role for immune maturation in disease susceptibility. The observed seasonal pattern suggests that viral exposures may act as triggers in susceptible patients.",

Its maturation from infancy to childhood is shaped by interacting environmental factors, including feeding mode, birth mode, and geographic location. A clinical study of 445 infants and toddlers (aged 0-24 months) from six socioeconomically diverse regions in China investigated age-related trajectories of gut microbiome and metabolomic development, with a particular focus on feeding mode. The study included a breastfed reference group and a formula-fed group that received an open-label formula containing a prebiotic mixture of short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides (scGOS/lcFOS, 9\u2009:\u20091). Longitudinal fecal samples were analyzed using shotgun metagenomic and metabolomic approaches. Feeding mode was strongly associated with variations in gut microbiome structure and function, along with birth mode and geographic location. Bifidobacterium and Bacteroides were the dominant taxa in both groups and exhibited dynamic abundance trajectories over time. Increased Bifidobacterium abundance was correlated with gene functions involved in starch and fatty acid metabolism as well as the fructose-6-phosphoketolase pathway (Bifid shunt). Comparative metabolomic analyses of amino acids and bile acids revealed highly similar metabolic profiles between the two groups. These findings highlight the association between feeding mode with the developing gut microbiome and describe age-dependent trajectories in Chinese children.",

Recent research indicates that MFGM plays a fundamental role in early-life health, particularly through its effects on gut microbiota development and immune system maturation. In the initial months of life, the infant's gut microbiome undergoes rapid colonization, essential for immunological tolerance, metabolic programming, and pathogen defense. Numerous studies have shown that MFGM components, including sphingomyelin, gangliosides, and glycoproteins, exhibit prebiotic-like effects by facilitating the proliferation of beneficial bacteria, such as Bifidobacterium and Lactobacillus species. Furthermore, MFGM supplementation in infant formulas has been linked to microbiota profiles that more closely resemble those of breastfed infants, enhanced gastrointestinal function, cognitive development, and a decreased incidence of diseases. This review clarifies how MFGM influences gut microbiota regulation, including increased barrier function, anti-inflammatory properties, and pathogen defense. Moreover, it highlights the possibility of MFGM-enriched dietary approaches to enhance proper gut colonization and promote long-term infant health, particularly in formula-fed populations. Although the results are encouraging, more longitudinal and mechanistic investigations are necessary to comprehensively clarify the influence of MFGM on the gut microbiome and the microbiota-mediated health benefits for growth and development.",

To improve harvest and purification processes, the development of continuous membrane-based operations, such as normal flow filtration (NFF) and single pass tangential flow filtration (SPTFF) for concentration were explored. This work was conducted using two model viruses, non-enveloped porcine parvovirus (PPV) and enveloped Suid herpesvirus (SuHV). The viruses are in the same family as the gene therapy vectors adeno associated virus and herpes simplex virus, respectively. SPTFF design started with batch TFF for membrane selection. Hollow fiber membranes with a 100 and 300\u2009kDa molecular weight cut off were defined for PPV and SuHV SPTFF operations, respectively. The SPTFF runs for PPV did not provide any concentration of the virus and low protein and DNA removal, unlike batch TFF. Two hollow fiber membranes run at 10\u2009mL/min and 2\u2009psi were the best condition for SuHV concentration, with approximately 100-fold titer concentration and protein and DNA removal of 37%\u2009\u00b1\u20095% and 32%\u2009\u00b1\u20098%, respectively. This concentration was superior to the batch TFF and indicated a strong dependence on flow rate and transmembrane pressure. For NFF, filters selection and performance tests were carried out for NFF of PPV and SuHV, as well as cleaning protocols for hollow fiber membranes. The ultimate goal is to integrate this work into the continuous purification of viral vectors produced in mammalian cell cultures to reduce costs and increase throughput.",

We therefore investigated the effects of convulsive seizures on cardiovascular and autonomic function in nonanesthetized sheep. Adult female sheep were instrumented to record arterial pressure, heart rate, electroencephalogram, electrocardiogram, and either cardiac output or cardiac and renal sympathetic nerve activity (SNA). Arterial blood samples were collected to assess blood biochemistry. Seizures were induced in nonanesthetized sheep by intravenous infusion of the proconvulsant pentylenetetrazol (PTZ; 5.0\u2009mg/kg/min for 4\u2009min). PTZ induced consistent generalized tonic-clonic seizures associated with abnormal activity on electroencephalogram. Convulsive seizures increased mean arterial pressure (79.1\u2009\u00b1\u20094.5\u2009mmHg to 128.5\u2009\u00b1\u20095.6\u2009mmHg, p\u2009<\u2009.0001) and cardiac output (4.1\u2009\u00b1\u2009.2 to 7.9\u2009\u00b1\u2009.5\u2009L/min, p\u2009<\u2009.0001) at 10\u2009min postseizure; these remained significantly above baseline for 60\u2009min (both n\u2009=\u200912).

We developed brain-age prediction models using diffusion magnetic resonance imaging-derived white matter features from two datasets: (1) the developing Human Connectome Project (dHCP; 368 healthy infants) and (2) a clinical sample collected at the Lucile Packard Children's Hospital (LPCH; 162 high-risk preterm infants). The goals of this study were (1a) to construct a white matter neonatal brain-age model including full-term and preterm neonates from a large research data set, (1b) to evaluate the accuracy of a separate brain-age model using the same architecture but trained and evaluated via cross-validation on a restricted subset of very preterm infants (<32 weeks gestational age) from the same data set to improve comparability with our clinical cohort; (2) to determine if a similar model can predict brain-age based on clinical MRI scans from high-risk neonates born preterm; and (3) to evaluate whether this preterm white matter-based brain-age model provides information about the infant's health beyond conventional clinical and demographic measures. White matter features demonstrated strong predictive performance in the dHCP dataset (within 3.9 days) and the LPCH clinical dataset (within 6.6 days). However, brain-age metrics (i.e., brain-age gap) showed no significant associations with health complications measured by a composite score of common prematurity complications. While tractometry-derived brain-age models accurately characterize brain maturation in the neonatal brain, their sensitivity to clinical complications in preterm infants appears limited. Global white matter maturation measures derived from clinical grade data may be insufficiently sensitive to capture the cumulative burden of prematurity-related morbidities, suggesting need for multimodal or longitudinal biomarkers.",

While KMC has traditionally been initiated after the infant stabilizes, immediate initiation of SSC has proven more effective in reducing neonatal mortality. However, despite its proven benefits, the adoption of immediate KMC remains a challenge. This study aims to develop and test an implementation model for integrating immediate KMC into the routine care of small and sick newborns in level 2 Special Newborn Care Units (SNCUs) in Bangladesh, Ethiopia, India, and Nigeria. This multicountry implementation research study will develop and evaluate a scalable model for integrating iKMC into newborn care across six study sites in four countries. The study will involve developing and optimizing an implementation model using a mixed-methods design, combining both qualitative and quantitative approaches. Formative research will be conducted to identify barriers and facilitators to the effective implementation of iKMC, guiding the development of the initial model. The study will benefit from concurrent programme learning, using both qualitative insights and outcome measurements, to iteratively refine the model and ensure high-quality, widespread implementation of iKMC. The study will provide insights into the effective integration of iKMC into existing health systems, addressing key challenges in low-resource settings. Findings will inform scalable strategies for widespread implementation, contributing to global efforts to enhance newborn care and reduce neonatal mortality.",

However, the potential impact of non-anemic prenatal iron deficiency (ID) on neonatal auditory function remains unclear. This study aimed to systematically explore the potential mechanisms by which maternal ID may affect auditory maturation of offspring. We analyzed population data from 696 mother-infant pairs, established ID mouse models (C57BL/6\u202fJ) during pregnancy, and conducted cellular experiments. In the human cohort, maternal serum ferritin (SF) and hemoglobin (Hb) were significantly negatively associated with the latency (ms) of auditory brainstem response (ABR) waves I, III, and V, as well as intervals (ms) of waves I-III, III-V, and I-V and summating potential/action potential ratios (%). Neonatal SF partially mediated the association between maternal iron status and auditory function, with mediation effects ranging from 28.57 to 76.32%. In mouse models, prenatal ID was associated with decreased wave I amplitude and extended latency in offspring, along with reduced ribbon synapses in inner hair cells, mitochondrial damage, and decreased enzyme activity in supporting cells. A metabolomics analysis revealed significant downregulation of pyruvate levels in the ID group, and exogenous supplementation with sodium pyruvate partially restored ribbon synaptic function. Collectively, prenatal ID may reduce fetal iron reserves, impair energy metabolism of cochlear supporting cells, inhibit ribbon synaptic maturation, and potentially contribute to auditory dysfunction. Our findings suggest that non-anemic maternal ID may be associated with delayed neonatal auditory maturation, highlighting the potential importance of iron intervention during pregnancy for improving neonatal auditory outcomes; however, causal relationships cannot be established from the observational human data, and the animal/cellular findings should be interpreted as supportive evidence requiring further validation.",
"42405008": "ID: 42405008\nTitle: Sally Clark: Trial and error by Judge and Jury.\nAbstract: Sally Clark's 1999 conviction for the murder of her two infant children represented one of the most conspicuous miscarriages of justice in modern English criminal law. A central component of the prosecution case was statistical evidence presented by Professor Sir Roy Meadow, which suggested that the probability of two sudden infant deaths occurring naturally within the same family was approximately one in 73 million. This paper examines three methodological limitations that affect the evidential value of that estimate. First, the family characteristics used to reduce the estimated probability of natural death were not considered in relation to the probability of the alternative explanation, thereby distorting comparative inference. Second, sudden infant death syndrome is a diagnosis of exclusion; population frequency data derived from such a category cannot determine causation in an individual case and are contingent on the limits of postmortem investigation. Third, the probability estimate was presented without reference to the likelihood of competing explanations, limiting its interpretive value. The paper further argues that the significance of the Clark case lies not only in the arithmetical error in the one in 73 million figure but in the broader evidential process by which probabilistic evidence was admitted, framed and interpreted within a criminal trial. The paper also examines the empirical and unstructured approach of English criminal courts to expert evidence. It considers the extent to which subsequent developments, including the Criminal Practice Directions 2023, respond to these difficulties, and compares that position with the contrasting procedural framework associated with the Daubert standard in the United States. The analysis situates the Clark case within broader issues concerning the interpretation, contextualisation and scrutiny of expert evidence in legal proceedings.",

In a longitudinal study of N = 133 mother-child dyads, we examined whether children's attachment-related behavioral patterns at age 3 were associated with functional connectivity during the viewing of attachment-related video clips. We further tested whether mother-child behavioral synchrony observed at ages 1 and 3 predicted children's functional connectivity. Neural activity was measured using functional near-infrared spectroscopy (fNIRS), targeting the prefrontal cortex (PFC), and temporoparietal junction (TPJ). Attachment-related behaviors were assessed through a structured observational procedure and rated using the Brief Attachment Screening Questionnaire (BASQ), and mother-child synchrony was coded using the Dyadic Interaction Coding (DIC) system. Children in the BASQ-derived insecure group exhibited greater intra-hemispheric connectivity, whereas those in secure group showed stronger inter-hemispheric connectivity. Mother-child synchrony at ages 1 and 3 did not independently predict later neural connectivity. Instead, mother-child synchrony at age 3 moderated the association between synchrony at age 1 and connectivity at age 3: synchrony at age 1 predicted reduced intra-hemispheric MTG connectivity only when synchrony at age 3 was high. These findings suggest that sustained mother-child synchrony may contribute to the functional organization of neural systems supporting attachment-related processing.",
"42406847": "ID: 42406847\nTitle: Extracting host-specific developmental signatures from longitudinal microbiome data.\nAbstract: Longitudinal microbiome studies provide critical insights into microbial community dynamics and their relation to host health. Tensor decompositions offer a powerful framework for the unsupervised analysis of such data, yielding interpretable low-dimensional temporal patterns. However, existing approaches based on the CANDECOMP/PARAFAC (CP) model assume common temporal dynamics for all subjects and therefore cannot capture subject-specific trajectories. To address this limitation, we introduce a novel analytical framework based on PARAFAC2 to explicitly model subject-specific variations, such as shifts and delays in temporal patterns. Through systematic comparisons on simulated and real-world datasets-including studies of infant gut maturation and dietary interventions-we demonstrate that PARAFAC2 outperforms CP in capturing subject-specific temporal trajectories, and enables the discovery of biologically relevant patterns that are overlooked by CP. Furthermore, we introduce replicability as a robust criterion for selecting the number of model components, ensuring that the extracted patterns are replicable.",

In Borneo, the population of wild bearded pigs (Sus barbatus) declined sharply during the period of regional ASF spread. This paper presents results of WWF-Malaysia surveys of bearded pigs in the Malaysian state of Sabah, in the northern part of Borneo, that showed changes over a 6-yr period (2019-25), starting before the 2021 ASF outbreak. Surveys were conducted along 2-km transects at 28 sites across 10 forest reserves and parks by using a combination of camera trapping and direct observations. The findings revealed high bearded pig occurrence in 2019-20, with a mean of 12.67 pigs per 100 camera-trap nights, followed by a precipitous decline from March 2021 to December 2022 and a slight increase in detections from 2023 onward. These results documented a marked decline of at least one order of magnitude in bearded pig detections across Sabah that coincided with the period of regional ASF spread, and they showed continued low populations even 5 yr after the epidemic was initially recorded. The survey findings provide an important ecologic baseline for monitoring bearded pig populations and highlight the need for integrated wildlife-disease surveillance in the region.",

While TREC-based screening is well established, the significance and management of isolated low KREC remain unclear. To evaluate the implications of two different regional post-screening algorithms for isolated low KREC and to characterize the clinical course, immunological profile, and follow-up of term newborns with transient B-cell lymphopenia. We performed a retrospective multicenter study of term newborns with isolated low KREC identified through NBS, confirmed B-cell lymphopenia, and subsequent normalization during follow-up. KREC levels, B-cell counts, and serum immunoglobulins were assessed longitudinally by RT-PCR and flow cytometry. Eighteen newborns were enrolled. At the first evaluation (V1; mean age 13.5\u2009days), all had marked peripheral B-cell lymphopenia (CD19+\u2009\u2264\u20092%; mean 54 cells/\u03bcL), although repeat dried blood spot (DBS) testing already showed KREC values above the diagnostic cutoff in 78%. By the second visit (V2; mean age 50\u2009days), B-cell percentages and absolute counts normalized in all infants, with emerging IgA and IgM production, and normal KREC on whole blood. No infectious or immunological complications were recorded over 39.5 person-years of follow-up (mean 2.3\u2009\u00b1\u20091.7\u2009years). Isolated low KREC at birth may identify newborns with transient B-cell lymphopenia that resolves during early infancy. Repeat KREC testing on a second DBS before referral may represent a pragmatic triage step to reduce unnecessary immunological evaluations, while preserving early assessment for newborns with persistent abnormalities. Prospective studies are needed to refine post-screening strategies.",

In addition to its swine host, PRV also infects a wide variety of animals as well as humans, posing a threat to veterinary public health. Thus, the development of potent antiviral drugs against PRV is required. Bovine lactoferrin (BLF) is widely known as an iron-binding glycoprotein in the transferrin family, which gains great attention for biomedical applications due to its beneficial physiological functions to human health as an antioxidant, antimicrobial, antiviral, anticancer, and immunomodulatory agent. In the work described here, we identified BLF as a novel and potent antiviral agent against PRV. BLF exhibited strong antiviral activity against PRV infection in multiple pig, human, and mouse permissive cells. Systematic analysis of the effect of BLF on PRV inhibition revealed that BLF blocks PRV attachment to target cells. Through surface plasmon resonance (SPR) analysis, BLF was demonstrated to directly interact with heparan sulfate (HS) proteoglycan (HSPG), a primary attachment receptor for PRV. Addition of exogenous HS completely abolished BLF inhibition of PRV attachment, demonstrating that BLF represses PRV attachment by interacting with cell-surface HS. However, BLF failed to inhibit the attachment of a PRV mutant virus with the deletion of glycoprotein C (gC), the primary viral envelop component for HS binding, suggesting that PRV gC is required for BLF inhibition of PRV infection. Cumulatively, these findings demonstrated that BLF inhibits PRV attachment by binding cell-surface HS to block the interaction between viral gC and HS.",

It also has persistently high maternal and infant mortality rates. Understanding PFL impacts on perinatal health is critical. We determined the impact of state PFL policies on perinatal health, with additional focus on socioeconomic disparities. We analyzed live singleton births using 2016 to 2022 birth certificate data (N = 11\u2009452\u2009411). We conducted a quasi-experimental analysis using heterogeneity-robust differences in differences, comparing pre-post trends in a comprehensive set of perinatal outcomes in jurisdictions with (Connecticut; Washington, DC; Massachusetts; New York; and Washington) and non-South states without PFL. Analyses were additionally stratified by maternal race and ethnicity, education, insurance, and Special Supplemental Nutrition Program for Women, Infants, and Children participation and adjusted for individual- and state-level time-varying covariates. Hypertensive disorders of pregnancy risk decreased by 13% following PFL implementation, as did excess gestational weight gain. PFL implementation was associated with modest increases in small for gestational age (0.290 percentage points [pp]; 95% CI, -0.300 to -0.102), preterm birth (0.590 pp; 95% CI, 0.465-0.715), and lower mean birthweight (-5.205\u2009g; 95% CI, -7.096 to -3.314). Socioeconomically disadvantaged subgroups saw higher risks of adverse birth outcomes but improved maternal outcomes. This study adds to prior research that found that PFL is associated with improvements in parental health and breastfeeding in the United States. Our findings suggest that state PFL policies had mixed impacts on perinatal health; further investigation of policy parameters and mechanisms is warranted.",
"42423462": "ID: 42423462\nTitle: The targeted cytosolic degradation of class I histone deacetylases is essential for efficient alphaherpesvirus replication.\nAbstract: Viral infection triggers a robust DNA damage response (DDR), reshaping the host chromatin landscape to facilitate viral replication. Here, we uncover a novel mechanism by which alphaherpesviruses exploit the DDR pathway. We demonstrated that herpes simplex virus 1 (HSV-1) and pseudorabies virus (PRV) induced selective degradation of class I histone deacetylases (HDAC1/2), leading to histone hyperacetylation and subsequent DDR activation. Strikingly, viral infection promoted nuclear export of HDAC1/2, followed by MDM2-mediated K63-linked polyubiquitination and proteasomal degradation in the cytoplasm. Pharmacological inhibition of either DDR signaling or HDAC1/2 nuclear export significantly affected viral replication in vitro and in vivo. Our findings reveal a unique viral strategy to hijack host epigenetic regulation for efficient replication, and identify potential therapeutic targets for alphaherpesvirus infections.",

In this work, we investigated for the first time the direct and indirect associations between nutrition intake, white matter microstructure and structural connectivity, and cognitive and academic outcomes. Using longitudinal data from typically developing children aged 2 to 14 years, we combined neuroimaging, dietary, and cognitive measures to test direct associations between nutrition and brain structure and connectivity, as well as cognitive and learning outcomes, and to assess whether brain development mediated these relationships. We found that specific nutrients, including DHA, sphingomyelin, iron, niacin, choline, and palmitoleic acid (omega-7), were associated with improved brain structure and connectivity, as well as better cognitive and learning outcomes. We also found that brain development partly mediated the association between childhood nutrition and learning outcomes. To our knowledge, this is the first study to show such a pathway in school-age children. These results add to the growing literature demonstrating the ongoing importance of nutrition beyond infancy in supporting childhood brain and cognitive development.",

Consequently, it poses additional risks for women with congenital heart disease (CHD), a leading cause of maternal mortality. Isolated right ventricular apical hypoplasia (IRVAH) is a poorly characterized CHD subset, with pregnancy outcomes remaining unreported. Our case of a primigravida with IRVAH underscores the need for heightened monitoring in this population. We present a 28-year-old primigravida at 28 gestational weeks referred for structural right heart failure and paroxysmal atrial fibrillation (AF) with no palpitations and dyspnea. Diagnostic evaluation revealed IRVAH on echocardiography, characterized by preserved left ventricular function, severe tricuspid regurgitation, and right ventricular dilation, alongside electrocardiography showing AF; cardiac magnetic resonance imaging (MRI) subsequently confirmed apical right ventricular hypoplasia with no associated structural anomalies. Management was guided by multidisciplinary consensus, initiating stabilization with oral metoprolol (12.5 mg per dose, twice daily) for resting heart rate control (target heart rate <110 bpm). Pregnancy prolongation strategies included weekly fetal growth scans, daily maternal oxygen saturation (SpO2)/blood pressure (BP) monitoring, and steroid coverage at 30 weeks for fetal lung maturation. Due to maternal AF recurrence despite therapy, fetal growth restriction (<10th percentile), and the need to avoid hemodynamic stress from labor, an elective cesarean delivery was scheduled at 32 weeks. A preterm infant (1,580 g, Apgar scores 9/10) was delivered via cesarean section under spinal-epidural anesthesia and transferred to the neonatal intensive care unit (NICU) for recovery. Postoperative AF in the mother was successfully controlled with increased oral metoprolol (25 mg per dose, twice daily). At the 1-, 3-, and 6-month follow-ups, maternal cardiac function remained at New York Heart Association (NYHA) class I, and no developmental delays were observed in the infant. This case demonstrates the critical value of multidisciplinary team collaboration in managing pregnancy complicated by IRVAH, underscoring the need for individualized monitoring and intervention strategies. These findings may serve as a reference for the clinical management of similar cases in the future.",

However, it remains unclear whether the guidance provided aligns with best practice guidelines. This review aimed to identify smartphone apps that provide safer sleep guidance and to assess their content, technical features, functionality, and quality. A secondary aim was to make recommendations on the improvements that existing and future apps can make to provide safer sleep guidance. In January 2026, we searched the UK Google Play Store and Apple App Store for safer sleep guidance apps for parents and caregivers of newborns and infants (babies aged \u226412 months). Information regarding content, technical features, and functional features was extracted and summarized descriptively. Each app was evaluated by 2 raters using the Mobile App Rating Scale (MARS) and the IMS Institute for Healthcare Informatics functionality score. Adherence to best practice sleep guidance was assessed using bespoke criteria. Interrater reliability was calculated. A total of 1345 apps were identified, with 12 meeting the inclusion criteria. All were free to download, with 42% (5/12) containing in-app purchases. Only 17% (2/12) were affiliated with a professional health, medical, clinical, or government body. All 12 apps contained some information regarding safer sleep practices, although this was addressed and named differently (eg, calling it cot death, sudden infant death syndrome, or safe sleep). Of the 9 criteria relating to safer sleep best practice guidance, the apps mentioned an average of 6.75 (SD 1.71; range 3-9) criteria. Some promoted unsafe sleep practices (ie, around swaddling and cosleeping). The apps included an average of 5.4 of the 11 IMS functionality criteria (SD 2.5; range 2-9). The mean MARS score was 3.7 out of 5 (SD 0.43; range 2.92-4.13), and most (11/12, 92%) had a minimum acceptability score of 3 or above. Two had been formally trialed or tested. Although the language used was considered accessible (easy to understand), none of the apps allowed the language to be changed (beyond English), and very few (3/12, 25%) enabled users to change to night/dark mode, which would be considered essential when using these apps at night. Several apps about safer baby sleep exist. Few discuss safer sleep guidance comprehensively or raise awareness about sudden infant death syndrome and its links with unsafe sleep. All the reviewed apps met the minimum acceptability criteria for quality; however, not many were formally trialed or tested. More long-term research should be conducted on the effectiveness of safer sleep apps on adherence to safer sleep guidance. We recommend that apps relating to infant and baby safety in general include information on realistic safer sleep practices that are informed by best practice guidelines and take a risk minimization approach.",

Recent studies suggest that the current dose may be too high. In the randomized multicenter BETADOSE trial, non-inferiority of the half dose compared to full dose was not shown for surfactant administration. Children with intra-uterine growth restriction have a higher risk of poor respiratory outcomes, including bronchopulmonary dysplasia, compared to those in other indications for antenatal corticosteroids. This post hoc study aims to compare respiratory outcomes between the half-dose and the full-dose groups in very preterm neonates, overall and according to indications for antenatal corticosteroids: inflammatory or vascular context including intra-uterine growth restriction. Eligible neonates were born\u2009<\u200932\u00a0weeks among those enrolled in the BETADOSE trial. The primary outcome was the occurrence of bronchopulmonary dysplasia. Multiple analyses adjusted for indications for antenatal corticosteroids, birthweight z-score, and gestational age were used. To account for multiple comparisons, p values were adjusted using the Bonferroni correction for the primary outcome. In the overall population and in the inflammatory context subgroup, there were no significant differences in respiratory outcomes, in particular surfactant use and bronchopulmonary dysplasia. The rate of discharge home with oxygen was higher in the half-dose group in the overall population. In neonates with intra-uterine growth restriction, surfactant use (63% vs 42%, p\u2009=\u20090.02) and bronchopulmonary dysplasia (40% vs 24%, p\u2009=\u20090.04) were more frequent in the half-dose group although no statistically significant difference was observed after correction using the Bonferroni method. \u00a0The impact of reducing the dose of antenatal corticosteroids may vary according to the underlying indication for administration. No firm conclusions can be drawn from these findings, which may reflect residual confounding, particularly in the subgroup with intra-uterine growth restriction. As such, this observation should be considered exploratory and further prospective studies are needed. \u2022\u00a0Antenatal corticosteroids are used to accelerate fetal lung maturation. Recent studies question the current dose of betamethasone.

The deep-sea environment of Barbados (200-5,776 m) accounts for 99.8% of its Exclusive Economic Zone (EEZ). Barbados is presently in the initial phases of developing a marine spatial plan for its EEZ. Comprehensive baseline information on the deep-sea ecosystems is crucial for evidence-based decision-making. This research assesses the state of deep-sea biological knowledge in Barbados via a comprehensive review of species records from peer-reviewed and grey literature, as well as museum and biodiversity databases. We found 1,589 biological records constituting 309 families and 624 species and morphospecies for Barbados' deep sea. Strikingly, richness analyses estimate that just 20% of the species and 48% of the families inhabiting Barbados' deep sea have been recorded. We also discuss limitations in existing knowledge, including vast geographic areas and depths still requiring research, as well as the varied methods of deep-sea observation and sampling utilised thus far, and the associated influence on the taxonomic composition of the known deep-sea community. Although limited, this assessment of deep-sea biodiversity information has provided insights to assist with the creation of a road map which decision-makers can utilize to guide future management and research activities.",

This retrospective study analyzed clinical data from children aged 0-13 years diagnosed with respiratory tract infections at Tianshui First People's Hospital between 2019 and 2024. The dataset included 79,703 complete blood count samples and 7,931 immunoglobulin (IgG, IgA, IgM) analysis samples. Non-parametric tests (rank-sum test) and generalized linear models (Gamma distribution with Log link function) were employed for statistical analysis to evaluate the effects of different years, age groups, genders, and diagnostic types (upper/lower respiratory tract infections) on immunological parameters. The study found that the COVID-19 pandemic had heterogeneous effects on various immune cell types. Neutrophil and monocyte counts showed an increasing trend during the pandemic, whereas lymphocyte, eosinophil, and basophil counts were suppressed-with lymphocyte reduction being particularly pronounced. The suppressive effect on basophils may be persistent. Compared with 2019, no significant changes were observed in immunoglobulin levels among children from 2020 to 2022. However, beginning in 2023, serum concentrations of immunoglobulin G and immunoglobulin M showed a marked increase. This upward trend persisted through 2024, accompanied by a concurrent rebound in lymphocyte counts. Further analysis of interaction effects among age, gender, and diagnosis revealed that the impact of the pandemic on immune development was also significantly influenced by these factors. The COVID-19 pandemic and associated public health interventions have altered children's patterns of pathogen exposure, delayed the development of adaptive immunity, and disrupted the balance between innate and adaptive immunity, thereby exerting complex and long-lasting effects on immune system maturation. These findings provide valuable data for understanding the response patterns of the children's immune system under exceptional public health events and offer guidance for formulating targeted child health policies, vaccination strategies, and clinical practices in the future.",

It focuses on medical guidance, emotional support, and post-birth care. A qualitative descriptive design was used. Five Norwegian women participated in individual in-depth interviews, providing insight into encounters with healthcare professionals across the care trajectory. Their experiences unfolded across four key moments: learning about the diagnosis, making a decision, giving birth, and leaving the hospital. Care was experienced as fragmented, intensifying emotional distress and uncertainty. Shifts between clinical and emotionally attuned language created cognitive dissonance, leading the women to question the legitimacy of their grief and maternal identity. These findings highlight the need for coordinated psychosocial and medical care that acknowledges maternal identity and affirms women's right to grieve.",

For this reason, we aimed to describe the changes in gut microbiota and neurobehavioral phenotypes across the lifespan of the MIA offspring. We administered poly(I:C) on gestational day 12 to induce MIA in pregnant C57 mice. Subsequently, we conducted behavioral phenotyping, a neuropharmacological sensitivity test, a morphological analysis of dendritic branches and spines, and a gut microbiota assessment in male offspring. Here, we performed a longitudinal analysis of gut microbiota maturation across development in poly(I:C)-MIA offspring and integrated these findings with behavioral and neuronal morphology assessments relevant to ASD and schizophrenia. Our results show that MIA treatment induces an increase in the marble burying test, which assesses repetitive and persevering behavior related to obsessive-compulsive disorder, as well as decreased social interaction, anhedonia, sensitivity to the psychotomimetic drug amphetamine, and a reduction of dendritic branches and spines in the pyramidal neurons of layers II/III of the prefrontal cortex. We also observed infant gut dysbiosis on postnatal day (PD) 30. This condition is unrelated to maternal vertical transferences and persisted until early adulthood (PD57) and adulthood (PD100). Our results show that MIA is a consistent and robust preclinical model of ASD/SCZ that allows identifying symptoms and signs of these disorders, which agrees with epidemiological human evidence. Additionally, the gut dysbiosis induced by MIA could be permanent, and since it is not induced by vertical transference, it could be supported by the brain-gut-microbiota axis effects. Additional neuroimmune and microbiological studies, such as microbiota transplantation or antibiotic interference, are necessary to better interpret the effects observed in this study.",

It contributes to substantial neonatal morbidity and mortality. Disturbances in the intestinal microbiome are crucial to disease pathogenesis. In preterm infants, an immature intestinal barrier, dysregulated immune responses, and environmental exposures altogether predispose to alteration in microbial colonization and intestinal inflammation. This review was done to present the current evidence on gut microbiome alterations associated with NEC in preterm infants. A systematic search of the MEDLINE and EMBASE databases was performed using search strategy related to prematurity, intestinal microbiota, and necrotizing enterocolitis. A total of 42 studies assessing microbial composition, microbial progression, or microbial functional patterns in relation to NEC were included. Across the included studies, NEC was commonly preceded by reduced microbial diversity, delayed maturation of anerobic communities, and expansion of Proteobacteria, particularly Enterobacteriaceae family such as Klebsiella and Escherichia. Longitudinal studies further showed that these microbial changes may become evident days to weeks before clinical disease, suggesting a potential window for early risk identification. Functional analyses also showed alterations in microbial metabolic pathways, including short-chain fatty acids, tricarboxylic acid intermediates, volatile compounds, and viral signatures that may lead to epithelial injury and inflammatory signaling. Clinical and environmental factors including antibiotic exposure, mode of delivery, feeding practices, and NICU microbial ecosystem are important determinants of neonatal gut microbiome development. Thus, the current evidence supports a reproducible pattern of intestinal dysbiosis preceding NEC. Better understanding of microbiome dynamics may aid early risk stratification and support microbiome-targeted preventive strategies in vulnerable preterm populations.",

Authors of this qualitative study examined parental perceptions and reported practices related to infant safe sleep among families who received a free portable crib after their infant's birth. Specifically, authors explored whether families used the portable crib to provide a safe sleep environment for their infants. Parents of infants aged 2 to 11 months who received a free portable crib were invited to participate in a structured 11-question interview assessing safe sleep perceptions and practices, including crib use. Eleven families participated in the study. Six themes emerged from the interviews: (1) parents recalled receiving safe sleep counseling, often in considerable detail; (2) many parents initially planned to bed-share before receiving the crib; (3) reported sleep practices frequently differed from established safe sleep recommendations; (4) parents described multiple reasons for not consistently following recommendations; (5) participants supported the continued provision of free cribs and safe sleep counseling; and (6) parents generally found the crib helpful, although it often was used alongside other sleep arrangements. Although parents recalled receiving safe sleep counseling, reported sleep practices frequently did not align with recommended guidelines. Further research is needed to better understand this gap and to identify strategies that improve adherence to safe sleep recommendations.",

Preimplantation Genetic Testing for Monogenic Diseases (PGT-M) offers a valuable reproductive option for at-risk couples seeking to prevent transmission of such conditions. This represents the first Brazilian case of a healthy birth following combined PGT-M and PGT-A for MMA known. After the neonatal loss of their first child due to mut0-type MMA, a couple underwent genetic testing, which identified compound heterozygosity in MMUT: a maternal deletion (c.1196_1197del) and a paternal duplication (c.213_216dup). Haplotype construction used parental and proband DNA. Two IVF cycles yielded 13 blastocysts; of these, one embryo was diagnosed as being both euploid and unaffected, and two were euploid and heterozygous carriers. One of those embryos was selected for transfer, resulting in an uneventful pregnancy and the live birth of a healthy female infant. This single case highlights the clinical utility of PGT-M to prevent the recurrence of a severe inborn errors of metabolism and underscores the importance of early genetic counseling in couples with prior adverse neonatal outcomes.",

Urine was analysed for prostaglandin E2 (PGE2) metabolites in a subgroup of cases. We identified 149 cases of SUPC, corresponding to an incidence of 31 per 100\u2009000 live births, exceeding that of early onset sepsis caused by Group B Streptococcus. Half the SUPC cases occurred during the first four postnatal hours. The mortality was 7% and 26% suffered from neurological sequelae. The highest risk of SUPC coincided with the postnatal peak in PGE2 levels. All newborn infants were at risk of SUPC, especially within 24\u2009h of birth. SUPC was associated with early unsupervised skin-to-skin care and bed sharing. Guidelines promoting safe sleep and skin-to-skin care should be implemented to prevent SUPC and save the lives of newborn babies.",

To evaluate school readiness at age 5 years and educational attainment at age 6 to 7 years in children born very preterm and to identify the early-life, neonatal, and socioeconomic factors associated with attainment. This retrospective cohort study included all infants born before gestational age (GA) 32 weeks in England who received care in a neonatal unit and survived to discharge. A linkage between the National Neonatal Research Database and the National Pupil Database was created to integrate neonatal clinical data with educational outcomes. The data analysis was performed between October 1, 2024, and October 31, 2025. Gestational age and area-level socioeconomic deprivation. The main outcome was school readiness at age 5 years (as measured by the Early Years Foundation Stage Profile [EYFSP]) and attainment in reading, writing, mathematics, and science at age 6 to 7 years. For each outcome, prevalence of not meeting the expected level of attainment across indices of socioeconomic deprivation and GA stratified by 23 to 26 weeks and 27 to 31 weeks were calculated. Of a total of 15\u202f857 children included (2595 born at GA 23-26 weeks [16.3%] and 13 262 born at GA 27-31 weeks [83.7%]; 8449 boys [53.3%]), 8602 (56.6%) did not meet the school readiness level at age 5 years, and 7789 (51.8%) did not meet expected attainment at age 6 to 7 years for writing, 7216 (48.1%) for math, 6354 (41.9%) for reading, and 5449 (36.0%) for science. Children born at GA 23 to 24 weeks had a higher odds of not meeting expected school readiness levels compared with those born at 31 weeks (adjusted odds ratio [AOR], 2.86 [95% CI, 2.19-3.73]). Children born in areas with the most deprivation had a higher risk of underattainment compared with those in areas with the least deprivation (EYFSP: AOR, 1.27 [95% CI, 1.11-1.45]). In adjusted models, male sex and season of birth were associated with increased risk (EYFSP: AOR, 1.96 [95% CI, 1.82-2.11] and 2.64 [95% CI, 2.41-2.90], respectively) alongside several potentially modifiable risk factors, including smoking during pregnancy (AOR range from 1.19 [95% CI, 1.08-1.31] for math to 1.31 [95% CI, 1.19-1.44] for reading); exposure to postnatal corticosteroids (EYFSP: AOR, 1.37 [95% CI, 1.13-1.65]); severe acquired neonatal brain injuries, particularly periventricular leukomalacia (EYFSP: AOR, 3.05 [95% CI, 2.04-4.58]) and hydrocephalus (EYFSP: AOR, 2.47 [95% CI, 1.48-4.13]); comorbidities of preterm birth, including necrotizing enterocolitis (EYFSP: AOR, 1.60 [95% CI, 1.20-2.14], retinopathy of prematurity (EYFSP: AOR, 1.46 [95% CI, 1.10-1.93], and bronchopulmonary dysplasia (EYFSP: AOR, 1.30 [95% CI, 1.18-1.44]); and nutrition during neonatal care (EYFSP: AOR, 1.19 [95% CI, 1.07-1.33] and 1.51 [95% CI, 1.37-1.66] for mixed feeding and exclusive formula feeding, respectively, vs breastfeeding). This cohort study of children born before GA 32 weeks found that preterm birth was associated with a substantial and persistent risk for educational underattainment across early school years, especially when combined with socioeconomic deprivation. Improving outcomes for children born preterm may require reducing social inequalities and minimizing comorbidities of preterm birth. Several modifiable early-life exposures offer practical targets for intervention, including maternal nonsmoking, appropriate corticosteroid use, and breastfeeding. Deferred school entry or targeted academic support may benefit children born very preterm, depending on birth season. These strategies may help parents, clinicians, educators, and policymakers improve long-term educational attainment for children born preterm.",
"42448743": "ID: 42448743\nTitle: Radiofrequency electrical conductivity reveals a distinct dimension of early human brain development.\nAbstract: Quantitative MRI has characterised early human brain development primarily through measures of water mobility, leaving other biophysical properties of maturing tissue unexplored. Here we show that radiofrequency electrical conductivity, reflecting ionic composition, membrane density and extracellular geometry in addition to water content, can be extracted retrospectively and at scale from the phase of conventional MRI acquisitions, revealing a distinct dimension of early brain tissue maturation and state. Applying electrical property tomography to 888 neonatal MRI sessions (784 subjects, 26-45 weeks post-menstrual age) alongside infant and childhood data, we find that whole-brain conductivity declines steeply during the perinatal period and remains independently associated with age after adjustment for mean diffusivity and ventricular volume, confirming that it represents a distinct developmental signal that is not reducible to tissue water content alone. Preterm birth was associated with elevated conductivity at term-equivalent age, particularly in deep grey matter. In neonates with hypoxic-ischaemic encephalopathy (n\u2009=\u200925), conductivity was elevated while mean diffusivity was reduced within the same tissue compartments, a dissociation indicating that these measures capture mechanistically distinct aspects of the tissue response to injury. These findings establish radiofrequency electrical properties as a new biophysical window on perinatal brain maturation and its perturbation by injury, extending quantitative MRI beyond measures of water mobility.",

Methods: Meconium samples were collected from 310 neonates born at 22-40 weeks of gestation, and 16S rRNA sequencing was conducted. After excluding small-for-gestational-age infants, the analyses included 151 samples from PGF+ infants and 131 samples from PGF- infants. Microbial composition, alpha and beta diversity were compared according to PGF status. Distance-based redundancy analyses (dbRDA) were conducted to evaluate the independent association between PGF and microbiome composition. Results: The core meconium microbiome differed between groups. PGF+ infants showed a predominance of Proteobacteria (36.60% vs. 27.96%), whereas PGF- infants had relatively higher abundances of Firmicutes (35.47% vs. 30.64%) and Bacteroidetes (28.96% vs. 26.19%) than PGF+ infants. GA-related microbial maturation patterns also differed between groups. At the genus level, the PGF- group showed significant positive correlations with GA for Faecalibacterium, Sutterella, Dialister, Megamonas, Escherichia/Shigella, and Roseburia after false discovery rate correction, whereas no genus-level correlation remained significant in the PGF+ group. Alpha diversity did not differ significantly between groups, whereas beta diversity differed modestly (R2 = 0.0087, p = 0.042). After adjustment for GA and birth weight, the PGF effect remained significant in the Bray-Curtis-based dbRDA model, whereas it was not significant in the Jaccard-based model. Conclusions: PGF was associated with abundance-based shifts within shared meconium taxa, suggesting subtle differences in early microbial developmental patterns among infants who later developed PGF.",

This scoping review collates the current knowledge about the benefits of carotenoids in improving visual and cognitive function outcomes in children. This review includes observational and interventional published studies to date (January 2026) through a literature search on PubMed, Web of Science, Embase, Mendeley, and Google Scholar database platforms. We have described and measured carotenoid status in diet, serum, skin, and human milk in relation to eye and cognitive development and function in children. Human body carotenoids, \u03b1-carotene, \u03b2-carotene, lycopene, cryptoxanthin, lutein, and zeaxanthin, have been detected in significant amounts in the brain, whereas the xanthophylls lutein, zeaxanthin, and meso-zeaxanthin, are found in the eyes. Lutein, zeaxanthin, and retinoids in the ocular tissue are responsible for visual function and have been associated with visual neurocognitive skills in children. In addition, lutein, zeaxanthin, and \u03b2-carotene have been associated with cognitive function tasks in infants and children. This review shows emerging evidence on the benefits of carotenoids in children, primarily from cross-sectional studies and longitudinal cohort studies. We found a paucity of carotenoid intervention and controlled trials for direct carotenoid exposure and its relative effect on neurocognitive function and visual milestone development during early life. Additionally, further long-term studies are required to confirm carotenoid exposure in early life and its benefits to eye health and cognitive skills outcomes in later life.",
"42451508": "ID: 42451508\nTitle: Nonlinear Measures Applied to Spontaneous Infant Movement Analysis: A Scoping Review.\nAbstract: Spontaneous movement analysis provides valuable information about the maturation of the central nervous system and the emergence of motor control strategies in very young babies. Nonlinear measures capture dynamic aspects of movement that cannot be represented by linear methods. However, their implementation in clinical practice faces challenges, including the lack of standardized protocols and accessible tools for routine use. This scoping review aimed to map and characterize the nonlinear measures used to analyze spontaneous infant movement, including assessment context, instruments, data collection protocols, and main variables. The review followed JBI methodology and PRISMA-ScR guidelines. Searches were conducted in PubMed\u00ae, Web of Science\u2122, IEEE Xplore\u00ae, ScienceDirect\u00ae, and Google Scholar for studies published from 1 January 2005 to 31 December 2025. Of 1166 records identified, 18 met the inclusion criteria. The nonlinear measures were grouped into five main methodological families: entropy-based measures (n = 10), state-space and dynamical systems measures (n = 4), recurrence-based analysis (n = 3), symbolic and discrete-state approaches (n = 3), and variance and frequency-based nonlinear descriptors (n = 1). Studies were conducted in laboratory settings (n = 6) and in hospital and/or home environments (n = 10). Two studies did not clearly specify the assessment context. Kinematic assessment was mainly performed using video-based systems (n = 7), accelerometers (n = 4), and wearable sensors (n = 2), with most studies focusing on the upper and lower limbs. Several investigations extended beyond single-joint analyses to examine inter-limb relationships and whole-body configurations, capturing spatial coordination patterns across multiple body segments. Kinetic assessment was conducted using pressure mats (n = 4) and force platforms (n = 1), with the center of pressure displacement as the primary outcome. Future research should prioritise methodological harmonisation and theoretical clarity. Consensus is needed regarding minimal data requirements, parameter selection, and reporting standards for commonly used nonlinear measures. Studies should also move beyond single-metric approaches and adopt multivariate frameworks that integrate complementary nonlinear metrics. The absence of standardised acquisition and analytical protocols currently limits cross-study comparability and hinders the clinical translation of nonlinear movement metrics as objective tools for early neurodevelopmental assessment.",
"42455951": "ID: 42455951\nTitle: Scent of a father: Paternal body odors boost interbrain synchrony.\nAbstract: Olfactory cues are ancient signals and mammalian young utilize maternal body odors (BO) to form a bond to their habitat in the absence of the mother, strengthen associative learning, and grow a social brain. Whether infants respond to their father's BO and how paternal BO impact their brain maturation is still unknown. Utilizing ecologically-valid paradigms with dual-electroencephalography recordings, we measured infant-father and infant-stranger interbrain synchrony during naturalistic interactions and assessed the effects of paternal BO. Infants show greater interbrain synchrony with father compared to a stranger male. Paternal BO increase infant-stranger interbrain synchrony and enhance the father-typical positive arousal, providing evidence that infants process their father's odor and can invoke his presence in his absence. Fathers contribute to brain maturation by enhancing cross-hemisphere connectivity in alpha rhythm that sustains attention regulation during stimulating social interactions. Paternal olfactory cues can invoke infants' associative learning and may push the development of more complex neural and behavioral competencies.",
"42457069": "ID: 42457069\nTitle: Maternal pathways linking sociocognitive resources and immune balance to infant neurodevelopment: from cytokines to education.\nAbstract: The COVID-19 pandemic renewed interest in prenatal immune exposures and offspring neurodevelopment. While maternal immune activation (MIA) is associated with neurodevelopmental disorders (NDD), emerging evidence suggests that immune balance-particularly within the IL-6/IL-10 axis-may be more informative than absolute inflammatory levels. In the COGESTCOV-19 cohort, 95 children (50 prenatally exposed to maternal SARS-CoV-2 infection; 45 controls) were reassessed at 26\u00a0months using the Bayley-III (cognitive, language, and motor domains). Group comparisons (ANOVA/ANCOVA) and linear and nonlinear regressions (GAMs) examined associations between Bayley-III scores and the maternal baseline IL-6/IL-10 ratio, focusing on samples obtained within 0-4\u00a0weeks post-infection/vaccination; sensitivity analyses extended this window to 9\u00a0weeks. No overall differences in Bayley-III outcomes were observed between exposed and control groups after covariate adjustment. However, time-sensitive nonlinear associations emerged. Among non-vaccinated mothers infected during pregnancy and sampled within 0-4\u00a0weeks post-infection, higher IL-6/IL-10 ratios were associated with lower model-estimated offspring expressive-language and fine-motor scores in specific analytical subsets. Vaccination was associated with higher IL-10 levels in controls, not cases, and longer post-vaccination intervals corresponded to declining IL-10 in controls. Independently, higher maternal education predicted better communication outcomes, while advanced maternal age showed nonlinear associations with poorer fine motor performance. Variation in maternal immune balance during infection may be associated with subtle, domain-specific differences in early neurodevelopment. These exploratory findings do not establish causal immune pathways, a clinical IL-6/IL-10 threshold, or a protective effect of vaccination and require independent replication.",
"42461965": "ID: 42461965\nTitle: The antiviral GTPase MxB is packaged into virions and binds via its N-terminal domain to alphaherpesvirus capsids.\nAbstract: The interferon-inducible myxovirus resistance proteins (Mx) belong to the dynamin-like GTPases; MxA is a restriction factor against several RNA viruses, while MxB restricts infections of lentiviruses and herpesviruses. Humans express MxA(1-662) with an N-terminal domain (NTD) of 43 residues, MxB(1-715) with an NTD of 91 residues, and a truncated MxB(26-715) with an NTD of 66 residues. Although the roles of the GTPase and stalk domains during infection are increasingly being elucidated, the functions of the different NTDs remain poorly understood. Using cell lines stably expressing Mx proteins, we show that MxB(1-715), but not MxA, inhibited infection by herpes simplex virus (HSV-1) and pseudorabies virus (PrV). Quantitative mass spectrometry and subviral fractionation experiments indicate that MxB(1-715), but not the truncated MxB(26-715) or MxA(1-662), was enriched in the tegument of HSV-1 and PrV virions. Moreover, dimeric, recombinant, chimeric proteins with the NTD peptides MxB(1-91) or MxB(1-35), and to a lesser extent MxB(26-91), bound to tegumented HSV-1 capsids, while MxA(1-43) did not. In contrast, de-tegumented HSV-1 and PrV capsids bound to proteins with MxB(1-91), but not to those with MxB(1-35) or MxA(1-43). Our findings indicate that the NTD of MxB is crucial to restrict HSV-1 and PrV infections, that newly assembled virions package MxB into the tegument around the capsid, and that both the N-terminal MxB amino acid residues 1-25 and 26-91 contribute to its binding to tegumented and de-tegumented herpesviral capsids.",

In this context, invasive or introduced woody species may contribute substantially to biomass accumulation in degraded drylands, although quantitative evidence for Neltuma juliflora remains limited. This study provides the first block-scale assessment of carbon stocks in N. juliflora stands on Santiago Island, Cabo Verde, using validated allometric equations and topsoil analyses across 11 sampling blocks. A total of 463 individuals were measured. Aboveground carbon stocks varied markedly among blocks, ranging from 27.4 to 85.3 Mg C ha\u207b1, and were strongly associated with variation in stand structure, particularly equivalent diameter, tree height and stand density. In contrast, soil organic carbon in the 0-20 cm layer remained comparatively low, averaging 7.1 Mg C ha\u207b1, and showed no significant radial trend with increasing distance from the tree. Instead, variation in soil carbon was more closely associated with block-level edaphic heterogeneity than with local canopy effects. Belowground carbon, estimated using a fixed root-to-shoot ratio, followed the same spatial pattern as aboveground biomass and should therefore be interpreted as a derived rather than independently measured pool. Overall, the results demonstrate that N. juliflora can support substantial woody carbon storage under semi-arid insular conditions, whereas shallow soil carbon remains limited. These findings provide an important baseline for dryland carbon assessment in Cabo Verde and support a cautious, site-specific evaluation of the species in restoration and climate-mitigation strategies given its recognised invasive potential.",

Beh\u00e7et's disease and antiphospholipid syndrome (APS) are two distinct immune-mediated disorders encompassed within this spectrum, both capable of causing intracardiac thrombi and systemic embolisation, which causes diagnostic and therapeutic challenges. While Beh\u00e7et's disease is a classic systemic inflammatory vasculitis, APS primarily represents a prothrombotic autoimmune disorder with variable inflammatory features.

Ubiquitin C-terminal hydrolase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP) are biomarkers of neuronal injury and cellular stress and may provide insight into fetal vulnerability in this context. UCH-L1 and GFAP concentrations were measured in umbilical cord blood from 85 neonates born to women who underwent hospital-based polysomnography during the third trimester. The apnea-hypopnea index (AHI, and rapid eye movement (REM)-AHI)) and mean nocturnal oxygen saturation (mSaO2) were assessed. SDB phenotypes (OSA n\u2009=\u200914; REM-OSA n\u2009=\u200925; and mSaO\u2082 \u226495% n\u2009=\u200931) showed no significant differences in UCH-L1 or GFAP compared with controls. However, UCH-L1 levels were higher in neonates exposed to shorter apnea-hypopnea (AH) events, and both maternal AH length and mSaO2 were negatively correlated with UCH-L1 concentrations. Overall, maternal SDB was not broadly associated with differences in UCH-L1 and GFAP levels. Nevertheless, elevated neonatal UCH-L1 linked to non-traditional metrics, such as AH length and mSaO\u2082, suggests fetal cellular stress and highlights its potential as an early biomarker of neurodevelopment risk.",

Modelling the Eastern Caribbean.\nAbstract: Rising out-of-pocket (OOP) health expenditures in the Eastern Caribbean Currency Union (ECCU) underscore persistent gaps in health insurance coverage. This paper develops a Health Insurance Policy Simulation Model (HIPSM) to assess the potential impact of employer health insurance mandates and health insurance tax credits (HITCs) across five small island developing states (SIDS): Antigua and Barbuda, Dominica, Grenada, St. Lucia, and St. Vincent and the Grenadines (SVG). Using social security and insurance data, the model estimates coverage gains, fiscal costs, and labour market effects under varying thresholds and tax credit levels. Results show that employer mandates and HITCs can reduce coverage gaps and OOP expenditure in these countries but are highly sensitive to design characteristics. The findings offer important guidance for SIDS exploring scalable pathways towards universal health coverage through private insurance mechanisms, particularly in the absence of comprehensive public healthcare financing systems.",

We analysed New Zealand coronial findings and recommendations to identify recurring modifiable risks, social determinants of health, and system-level failures that might inform prevention strategies. A structured thematic synthesis was conducted on 127 New Zealand coronial findings and recommendations released between 2012 and 2025. Data were abstracted on infant demographics, sleep environments, caregiver factors, socioeconomic determinants, and the nature of specific coronial recommendations. Bed sharing was present in 81% (n\u2009=\u2009103) of cases. Maternal smoking was documented in 34 cases. Deaths clustered in early infancy, with 50% occurring before 3 months of age. Social complexities, including overcrowding, damp housing, and financial hardship, contributed to the sleep environment in 60% of cases (n\u2009=\u200976). Coroners issued 22 distinct types of recommendations targeting systems-level rather than just individual change. Findings show that sudden infant deaths are complex, with contributing factors operating at many levels and not simply due to parent's failure to follow prevention advice. SUDI prevention must shift from parental messaging to include multi-level interventions that address structural poverty, prioritised provision of in-bed sleepers, agency accountability, and mandatory workforce training.",
"42474821": "ID: 42474821\nTitle: Can slow and (un)steady still win the race? A narrative review of developmental gait characteristics and clinical implications in children born preterm.\nAbstract: Independent walking is more than a developmental milestone, as it reflects the integration of neuromuscular maturation, postural control, and sensorimotor coordination. In children born preterm, both the timing and the characteristics of independent walking may differ from those observed in term-born peers. This narrative review synthesizes current evidence on independent walking acquisition and gait features in preterm-born children throughout different stages of life, from toddler to school age, and discusses the clinical implications of quantitative gait assessment, with a focus on innovative wearable technologies, during neurodevelopmental follow-up. Preterm birth is consistently associated with a 1-2-month delay in independent walking onset compared with term-born peers, even after correction for gestational age (GA), with greater delays reported in infants born at lower GA or with very low birth weight (BW). Beyond milestone attainment, both qualitative and quantitative studies describe less mature gait patterns during early walking and the preschool years, including shorter step length, wider base of support, prolonged double-support phase, increased temporal variability, and reduced gait complexity. These characteristics likely reflect compensatory strategies related to immature postural control and sensorimotor organization. Although many spatiotemporal parameters improve with age and walking experience, subtle differences may persist into school age, particularly under more demanding conditions such as dual-task walking. However, currently available studies on preterm gait are quite heterogeneous in terms of GA, BW, and/or individual walking experience of included individuals and gait analysis methods employed. Furthermore, evidence regarding gait characteristics in preschool and school-aged preterm children is still relatively scarce, thus hampering a deeper understanding of preterm-born children's gait development after the toddler stage. \u00a0Instrumented gait analysis systems and wearable technologies, including inertial measurement units, enable objective and ecologically valid assessment of gait performance. Quantitative gait parameters have shown associations with standardised gross motor scores and may provide additional information beyond milestone history alone. Incorporating structured quantitative gait assessment into longitudinal follow-up programmes could support more detailed monitoring of motor development and inform individualised rehabilitation planning in children born preterm. \u2022\u00a0Children born preterm generally achieve independent walking later than term-born peers and may show immature gait features, particularly during the first years of life. \u2022\u00a0Most available evidence is heterogeneous and focuses mainly on walking onset or early gait, with limited data extending into preschool and school age. \u2022\u00a0This review integrates evidence on gait development from the fi rst independent steps to school age, identifying persistent abnormalities mainly in children born at lower gestational ages, with lower birth weight, or under demanding walking conditions. \u2022\u00a0It highlights the potential role of quantitative gait analysis and wearable inertial sensors as complementary tools for longitudinal neurodevelopmental follow-up and individualized rehabilitation planning.",

Recent global estimates suggest that inadequate breastfeeding is responsible for approximately 16% of child deaths worldwide each year, highlighting the ongoing need to strengthen support systems to improve infant and young child feeding practice in Bangladesh, 55% of infants under six months of age are exclusively breastfed. To improve breastfeeding rates and reduce infant mortality, the Government of Bangladesh enacted the Breast-milk Substitute (BMS) Act, 2013, and its Rules in 2017 to regulate the marketing of breast-milk substitutes. The study aimed to assess violations of the BMS Act, 2013, and Rules, 2017, focusing on the types, actors, and settings of such violations, while also raising awareness of the Act among key stakeholders and the public. We carried out a cross-sectional survey among 818 retail outlets and pharmacies; 969 baby-friendly hospitals; 969 doctors, nurses, and other health professionals; and 315 mothers with children aged 0-24 months across eight divisions of Bangladesh from August 2016 to December 2019. Data were collected through structured interviews, direct observations, and document reviews using a modified International Baby Food Action Network-International Code Documentation Centre (IBFAN-ICDC) protocol and the BFHI Hospital External Assessment Tool. All retail outlets surveyed (n\u2009=\u2009818) sold unregistered BMS products, and all displayed promotional materials. These retail outlets also sold BMS products labeled with health and nutrition claims. In hospitals, 25.5% of doctors (n\u2009=\u2009247) and 21.3% of nurses and other health professionals (n\u2009=\u2009206) promoted BMS without medical indication. Additionally, 32.0% of health facilities (n\u2009=\u2009300) reported providing financial incentives to health professionals to participate in events sponsored by BMS manufacturers. Furthermore, BMS manufacturers violated the BMS Act, 2013 by establishing breastfeeding corners in 164 hospitals (17.5%). This study identified extensive violations of the BMS Act 2013 and its Rules 2017 in Bangladesh, revealing unethical promotion and distribution of BMS. Health professionals in BFHI-trained hospitals played a significant role in these breaches, contributing to the erosion of breastfeeding practices. Urgent monitoring and enforcement are needed to protect infant health and uphold national regulations.",

Based on the analysis of international guidelines and consensus statements, such as those published by European Society for Pediatric Gastroenterology, Hepatology and Nutrition, Latin American Society of Pediatric Gastroenterology, Hepatology and Nutrition, and the World Health Organization, members of the Mexican Academy of Pediatrics review the main points of convergence and controversy related to the initiation, progression, and characteristics of CF during the first two years of life. The document highlights that this period is critical for growth, neurological development, immune maturation, and the establishment of healthy eating habits in the long term. Likewise, it emphasizes the relevance of the first 1000 days of life and the need to promote breastfeeding, dietary diversity, and the timely introduction of foods rich in essential nutrients. The review also addresses current topics such as the early introduction of allergenic foods, the role of different food textures, the prevention of obesity and allergies, as well as the importance of avoiding sugar-sweetened beverages, ultra-processed foods, and restrictive diets without specialized supervision. From the Mexican perspective, it is recognized that international recommendations must be contextualized according to the epidemiological, cultural, and social realities of the country. Finally, the Academia Mexicana de Pediatr\u00eda proposes practical recommendations directed at healthcare professionals to promote responsive, safe, and evidence-based CF that contributes to the overall well-being of Mexican infants.

Asimismo, se enfatiza la relevancia de los primeros 1,000 d\u00edas de vida y la necesidad de promover la lactancia materna, la diversidad alimentaria y la introducci\u00f3n oportuna de alimentos ricos en nutrimentos esenciales. La revisi\u00f3n tambi\u00e9n aborda temas actuales como la introducci\u00f3n temprana de alimentos alerg\u00e9nicos, el papel de las diferentes texturas, la prevenci\u00f3n de obesidad y alergias, as\u00ed como la importancia de evitar bebidas azucaradas, ultraprocesados y dietas restrictivas sin supervisi\u00f3n especializada. Desde la perspectiva mexicana, se reconoce que las recomendaciones internacionales deben contextualizarse seg\u00fan las realidades epidemiol\u00f3gicas, culturales y sociales del pa\u00eds. Finalmente, la Academia Mexicana de Pediatr\u00eda propone recomendaciones pr\u00e1cticas dirigidas a profesionales de la salud, con el fin de favorecer una AC perceptiva, segura y basada en evidencia cient\u00edfica, que contribuya al bienestar integral de las y los lactantes mexicanos.",
"42479854": "ID: 42479854\nTitle: Early-Life Intervention with Bifidobacterium longum subsp. infantis CCFM1269 Alleviates Atopic Dermatitis in Mice via the Indole-3-Lactic Acid-AHR Signaling Pathway.\nAbstract: Atopic dermatitis (AD) is a prevalent early childhood inflammatory skin disease frequently linked to gut dysbiosis. While Bifidobacterium longum subsp. infantis is a pioneer infant gut colonizer driving immune maturation, its role in AD prevention remains unclear. Here, we investigated early life intervention with B. longum subsp. infantis CCFM1269 using a 2,4-dinitrofluorobenzene (DNFB)-induced murine AD model. Oral administration of CCFM1269 significantly ameliorated AD symptoms, reducing skin/ear thickness, dermatitis scores, and serum IgE. Mechanistically, CCFM1269 modulated the systemic Th1/Th2 balance by downregulating TSLP, IL-4, and IL-13, while upregulating IFN-\u03b3. Notably, CCFM1269 produced indole-3-lactic acid (ILA). Via the gut-skin axis, ILA activated the aryl hydrocarbon receptor (AHR) and its target CYP1A1 in skin tissues, strengthening the epidermal barrier. Additionally, AD mitigation was associated with gut microbiota reshaping. Ultimately, CCFM1269 alleviates AD primarily through the ILA- AHR signaling pathway, highlighting its potential as a functional food ingredient for early life AD prevention."
