ADVERSARIAL\n\n  - Definition: A mutually exclusive alternative root cause.\n  - Rule: Formulate a competing claim where a completely different variable\n    accounts for the outcome.\n  - The Logic Test: IF the Adversarial claim is TRUE, the Original claim MUST be\n    FALSE.

Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

Pets may be exposed through accidental over-administration of a prescribed veterinary drug, intentional administration of a human drug that owners do not realize is unsuitable for animals, or access to unattended medications. Our objective was to document cases of exposure and toxicosis due to suspected and confirmed pharmaceutical ingestion in dogs admitted to a veterinary teaching hospital over a 6-year period (2018 to 2023). Medical records were retrieved from the veterinary hospital database using keywords related to general poisoning. Results were then filtered using keywords related specifically to pharmaceutical ingestion while excluding non-pharmaceutical poisoning cases. Information pertaining to hospitalization, patient signalment, treatment, and case progression was collected and analyzed to characterize common factors in canine pharmaceutical poisoning cases. Pharmaceutical ingestion was reported in 223 canine poisoning cases (confirmed in 102 cases) over 6 y. There were 32 categories of pharmaceutical ingested over the study period. The most common were nonsteroidal anti-inflammatory drugs (n = 86) and acetaminophen (n = 29). The most common patient signalment was spayed female, young (\u22644 y), and large breed (particularly, Labrador retrievers). Normal clinical examinations on presentation were noted in 164 cases. Accidental drug exposures were more common than intentional pharmaceutical administrations (n = 211 and n = 12, respectively). The occurrence of cases related to exposure to human pharmaceuticals was 5\u00d7 that of cases related to veterinary pharmaceuticals. Only 1 dog of 223 was euthanized, for a survival-to-discharge rate of 99.6%. The most common therapies administered were emesis induction, activated charcoal, fluid support, and gastroprotectant. Pharmaceutical exposure, especially from over-the-counter human medications, was a common reason for hospital admission among the dogs described in this study. Improved client education is needed to avoid preventable pharmaceutical exposures.

The aim of this study was to assess the pharmacokinetics of acetaminophen in both fed and fasted Labrador Retrievers after a single intravenous and oral administration (20\u00a0mg/kg). Six healthy dogs underwent three treatments in a randomized block study (a, n\u00a0=\u00a02; b, n\u00a0=\u00a02; c, n\u00a0=\u00a02). In phase one, group a received acetaminophen intravenously, group b and c orally after being fasted and fed, respectively. In phase two and three, groups were swapped, and the experiment was repeated. At the end of the trial, each dog received the same treatment. Acetaminophen plasma concentrations were detected using a validated HPLC-UV method. The pharmacokinetic analysis was performed using a noncompartmental model. Clearance, volume at steady state and half-life of acetaminophen in Labrador Retrievers were 0.42\u00a0L/kg\u00a0hr, 0.87\u00a0L/kg and 1.35\u00a0hr, respectively. No significant statistical differences were found between fasted and fed dogs regarding maximum plasma concentration, time at maximum concentration and bioavailability as measured by the AUC. Feeding does not significantly affect the acetaminophen oral pharmacokinetics."

Prospective randomized experimental trial. A total of 20 healthy dogs - 10 Beagles and 10 GE (six males and four females in both groups). Acetaminophen (10 and 20 mg kg-1) was administered intravenously (IV) to the dogs on two different occasions. Plasma concentrations were analysed by high-performance liquid chromatography. PK analysis was undertaken using compartmental modelling with ADAPT 5 software. Simulations after multiple IV doses were investigated. Clinical laboratory values such as red blood cell (RBC) count, haemoglobin (Hb), haematocrit (Ht), white blood cell (WBC) count, platelet count, total proteins, alanine aminotransferase (ALT), aspartate aminotransferase, urea and creatinine were measured before and 24 hours after acetaminophen administration in combination with clinical examination to assess side effects resulting from the drug. A two-compartmental model best described time-concentration profiles of acetaminophen. PK parameters were different as a result of a breed effect. For doses of 10 and 20 mg kg-1, respectively, clearance values were 1.70 (1.15-2.27) and 1.62 (1.06-2.86) L kg-1 hour-1 for Beagles and 1.18 (0.70-1.39) and 1.08 (0.67-1.35) L kg-1 hour-1 for GE; elimination half-life values were 2.64 (0.52-4.46) and 2.86 (0.87-4.63) hours for Beagles and 3.49 (1.89-7.80) and 4.57 (2.08-8.90) hours for GE. Significant differences were also found between GE and Beagles in the RBC count, Ht, Hb, WBC count and serum ALT before drug administration, and these differences were maintained 24 hours later, independent of the dosage used. For each breed, no side effects resulting from IV acetaminophen administration were observed at doses of either 10 or 20 mg kg-1. IV PK of acetaminophen was different between Beagles and GE dogs. Side effects were not detected. Further studies are necessary to evaluate the PK in a clinical context."

Two groups were studied: vehicle- (n=10) and acetaminophen-treated (n=10) dogs. All dogs were obtained from the same vendor, and there were no significant differences in their ages (18 +/- 2 mo), weights (24 +/- 1 kg), or housing conditions. Selected physiological data, e.g., coronary blood flow, nonspecific collateral flow, epicardial temperature, heart rate, systemic mean arterial pressure, left ventricular developed pressure, the maximal first derivative of left ventricular developed pressure, blood gases, and pH, were collected at baseline and during regional myocardial ischemia and reperfusion. There were no significant differences in coronary blood flow, nonspecific collateral flow, epicardial temperature, heart rate, systemic mean arterial pressure, or blood gases and pH between the two groups at any of the three time intervals, even though there was a trend toward improved function in the presence of acetaminophen. Infarct size, the main objective of the investigation, was markedly and significantly reduced by acetaminophen. For example, when expressed as a percentage of ventricular wet weight, infarct size was 8 +/- 1 versus 3 +/- 1%(P <0.05) in vehicle- and acetaminophen-treated hearts, respectively.

Two groups were studied: vehicle- (n=10) and acetaminophen-treated (n=10) dogs. All dogs were obtained from the same vendor, and there were no significant differences in their ages (18 +/- 2 mo), weights (24 +/- 1 kg), or housing conditions. Selected physiological data, e.g., coronary blood flow, nonspecific collateral flow, epicardial temperature, heart rate, systemic mean arterial pressure, left ventricular developed pressure, the maximal first derivative of left ventricular developed pressure, blood gases, and pH, were collected at baseline and during regional myocardial ischemia and reperfusion. There were no significant differences in coronary blood flow, nonspecific collateral flow, epicardial temperature, heart rate, systemic mean arterial pressure, or blood gases and pH between the two groups at any of the three time intervals, even though there was a trend toward improved function in the presence of acetaminophen. Infarct size, the main objective of the investigation, was markedly and significantly reduced by acetaminophen. For example, when expressed as a percentage of ventricular wet weight, infarct size was 8 +/- 1 versus 3 +/- 1%(P <0.05) in vehicle- and acetaminophen-treated hearts, respectively. When infarct size was expressed as percentage of the area at risk, it was 35 +/- 3 versus 13 +/- 2% (P <0.05) in vehicle- and acetaminophen-treated groups, respectively.

Drugs were administered orally 2 hours before and for 48\u2009hours after surgery at the licensed dose. Anaesthesia was standardised. Dogs received buprenorphine 6 hourly for the first 24\u2009hours after surgery. Outcome assessments were made pretrial and at regular intervals up to 48\u2009hours after extubation and comprised the Glasgow Composite Measure Pain Score-Short Form, visual analogue scale for sedation and inflammation and mechanical nociceptive threshold (MNT). Non-inferiority of paracetamol/codeine compared with meloxicam was defined using a non-inferiority margin (\u0394) against the 95 per cent confidence interval of the difference between the treatment means. Pain scores were low in both treatment groups. With the exception of MNT all upper 95 per cent confidence intervals for the differences between outcome variable treatment means were within +\u0394 for each variable, establishing non-inferiority for each outcome variable. Paracetamol/codeine is a useful perioperative analgesic that within the context of the perioperative analgesia regimen studied (methadone premedication, buprenorphine for the first 24\u2009hours after surgery) shows non-inferiority to the NSAID meloxicam."

Diabetic and non-diabetic patients (total 54 dogs) undergoing unilateral or bilateral phacoemulsification were recruited to this placebo-controlled, prospective study. The control group received 1\u2009ml/kg saline via intravenous infusion while the treatment group received 10\u00a0mg/kg paracetamol via intravenous infusion. Infusions were administered 30\u00a0min prior to surgery and repeated 12\u00a0h following initial administration. All patients received topical latanoprost at the conclusion of surgery. Intraocular pressure (IOP) was measured before premedication (baseline), and at 1\u00a0h, 3\u00a0h, 5\u00a0h and 18\u2009h following extubation. POH was defined as an IOP above 25\u2009mmHg (POH25). In addition, the number of patients with an IOP exceeding 20\u2009mmHg was analyzed (POH20).

When comparing groups, treatment with paracetamol showed a statistically significant reduction in the incidence of POH20, although no differences were observed in the incidence of POH25 between groups. Further studies are warranted to explore whether alternative drug regimes or routes of administration can provide enhanced efficacy in the prevention of POH25."

Enteric-coated granules containing cetirizine dihydrochloride (CET) were prepared in three particle sizes, 200, 660, and 1,200 \u00b5m (D50). To mark IMMC timing and water movement from the stomach, enteric-coated aspirin tablets and acetaminophen solution were used. To six fasted beagle dogs with 50 mL of acetaminophen solution was administered each granule size as a multiple-unit and a single enteric-coated aspirin tablet (3-period crossover study). No significant difference in pharmacokinetic parameters of CET after oral administration of different particle sizes was observed. However, the appearance time of CET in plasma with smaller granules (200 and 660 \u00b5m) was significantly faster than that of salicylic acid (a major metabolite of aspirin) in all dogs. In the case of the largest granules (1,200 \u00b5m), no significant time difference was observed in the appearance of both compounds in plasma. Furthermore, in two dogs, both compounds appeared at the same time, implying IMMC-regulated gastric emptying for the largest CET granules. These results support a particle size threshold between 660 and 1,200 \u00b5m for gastric emptying without IMMC action in fasted beagle dogs."

Following oral administration, a solid dosage form must disintegrate and the drug dissolve, thereafter permeating the intestinal mucosa. Several different in vitro methods are used to investigate these processes, i.e., disintegration tests, dissolution tests, and permeability models. However, the actual behavior of oral dosage forms in the environment of the gastro-intestinal tract is not very well elucidated using these conventional methods. In this study, the use of capsule endoscopy to determine tablet disintegration in vivo was assessed. Panadol and Panadol Rapid (acetaminophen/paracetamol) were used as the test material. The in vivo tablet disintegration behavior in beagle dogs was assessed by the use of capsule endoscopy. The in vitro tablet disintegration behavior was assessed using the European Pharmacopeia (Ph. Eur.) disintegration test. The study showed that the in vivo disintegration times of Panadol and Panadol Rapid were 24.7 and 16.5 min, respectively, when determined by capsule endoscopy, which corresponded to the pharmacokinetic data. By contrast, the in vitro disintegration times of the same formulations were 5.5 and 4.0 min, respectively, when determined by the Ph. Eur. disintegration test. In conclusion, capsule endoscopy can be used to determine the in vivo tablet disintegration behavior. By contrast, the in vitro methods appear to not be predictive of the disintegration behavior in vivo but may be used to rank the order the formulations with respect to disintegration time."

This study compared the serum biochemical changes and postoperative analgesic effects of paracetamol, meloxicam, and carprofen in bitches submitted to an ovariohysterectomy using the Dynamic Interactive Visual Analog Scale (DIVAS) and Pain Scale of the University of Melbourne (UMPS) scoring systems. Thirty bitches of different breeds underwent elective ovariohysterectomies and were randomly assigned to one of three treatment groups: a paracetamol group [15 mg kg-1 intravenous (IV)], a carprofen group (4 mg kg-1 IV), and a meloxicam group (0.2 mg kg-1 IV). All treatments were administered 30 minutes prior to surgery. Paracetamol was administered every 8 hours postoperatively for 48 hours total, while carprofen and meloxicam were intravenously administered every 24 hours. An evaluation of post-surgical pain was done with the DIVAS and the UMPS. The first post-surgical pain measurement was performed 1 hour after surgery and then 2, 4, 6, 8, 12, 16, 20, 24, 36, and 48 hours after surgery. All groups exhibited a gradual reduction in pain throughout the postoperative period in both scales; however, neither scale significantly differed between the three treatment groups (P > 0.05) during the 48 postoperative hours. Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy. The present study demonstrates that paracetamol may be considered a tool for the effective treatment of acute perioperative pain in dogs. Furthermore, this drug led to no adverse reactions or changes in the parameters assessed in the present study, indicating its safety."

This study evaluated the PK, postoperative analgesic effects, pharmacodynamics (PD), and safety of intravenous acetaminophen in dogs undergoing laparoscopic ovariohysterectomy. In a randomized, blinded trial, two doses of acetaminophen (10 and 20\u00a0mg/kg IV every 8\u00a0h for 24\u00a0h) were compared to buprenorphine (20\u00a0\u03bcg/kg IV every 8\u00a0h). The first dose was administered at extubation. Pain was assessed using the Glasgow Composite Measure Pain Scale-Short Form (CMPS-SF) and mechanical nociceptive thresholds during 24\u00a0h. A nonlinear mixed-effects model was used to characterize drug disposition, identify plasma analgesic concentration thresholds, and describe pain score evolution over time. Haematological, hepatic, and renal parameters were measured before and 24\u00a0h after treatment. Fifty-nine dogs were included. Both acetaminophen doses provided analgesia comparable to buprenorphine. CMPS-SF scores mostly remained between 0 and 2. PK was best described by a two-compartment model, with peak concentrations of 11.49 (7.89\u00a0%) and 19.78 (5.18\u00a0%) \u03bcg/mL and the lower concentrations of 0.11 (71.73\u00a0%) and 0.24 (62.06\u00a0%) \u03bcg/mL for 10 and 20\u00a0mg/kg, respectively. The PD model demonstrated sustained analgesia over time. Greyhounds exhibited higher pain scores at several time points, suggesting breed-specific differences in pain sensitivity and drug disposition. No adverse effects were observed. These findings support the use of acetaminophen as a safe and effective analgesic for postoperative pain management in dogs, with the potential need for individualized protocols based on breed-specific responses."

A comprehensive non-clinical safety program was conducted to support first-in-human and clinical efficacy studies based on preclinical data suggesting that the compound has comparable or enhanced antinociceptive and antipyretic efficacy without causing hepatotoxicity at supratherapeutic doses. No hepatic toxicity was noted in a mouse model sensitive to acetaminophen hepatotoxicity or in rats, dogs, and non-human primates in 28-day repeat dose toxicity studies at and above doses/exposures at which acetaminophen is known to cause hepatotoxicity. In the 28-day toxicity studies, all treatment-related findings were monitorable and reversible. Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen. This finding is considered not relevant to humans due to species differences in metabolism. Thyroid hypertrophy and hyperplasia were also observed in dogs and were shown to be a consequence of a species-specific UGT induction also demonstrated with increased thyroid hormone metabolism. Indirect bilirubin elevation was observed in rats as a result of UGT1A1 Inhibition. JNJ-10450232 (NTM-006) had no toxicologically relevant findings in safety pharmacology or genotoxicity studies.

Prescription of paracetamol for both acute and chronic pain was reported by most veterinarians 778/984 (79.1%). 96.5% of veterinarians reported not observing adverse effects when prescribing paracetamol. The majority of veterinarians responding to our survey prescribe paracetamol to dogs and generally perceived it as safe. Nonetheless, the widespread prescribing of paracetamol among veterinarians in Australia and New Zealand should not be interpreted as an endorsement of use or proof of efficacy for analgesia in dogs. Isolated reports of prescription to cats suggest areas where further education is warranted given the risk of life-threatening paracetamol toxicity in cats."

Pets may be exposed through accidental over-administration of a prescribed veterinary drug, intentional administration of a human drug that owners do not realize is unsuitable for animals, or access to unattended medications. Our objective was to document cases of exposure and toxicosis due to suspected and confirmed pharmaceutical ingestion in dogs admitted to a veterinary teaching hospital over a 6-year period (2018 to 2023). Medical records were retrieved from the veterinary hospital database using keywords related to general poisoning. Results were then filtered using keywords related specifically to pharmaceutical ingestion while excluding non-pharmaceutical poisoning cases. Information pertaining to hospitalization, patient signalment, treatment, and case progression was collected and analyzed to characterize common factors in canine pharmaceutical poisoning cases. Pharmaceutical ingestion was reported in 223 canine poisoning cases (confirmed in 102 cases) over 6 y. There were 32 categories of pharmaceutical ingested over the study period. The most common were nonsteroidal anti-inflammatory drugs (n = 86) and acetaminophen (n = 29). The most common patient signalment was spayed female, young (\u22644 y), and large breed (particularly, Labrador retrievers). Normal clinical examinations on presentation were noted in 164 cases. Accidental drug exposures were more common than intentional pharmaceutical administrations (n = 211 and n = 12, respectively). The occurrence of cases related to exposure to human pharmaceuticals was 5\u00d7 that of cases related to veterinary pharmaceuticals. Only 1 dog of 223 was euthanized, for a survival-to-discharge rate of 99.6%. The most common therapies administered were emesis induction, activated charcoal, fluid support, and gastroprotectant. Pharmaceutical exposure, especially from over-the-counter human medications, was a common reason for hospital admission among the dogs described in this study. Improved client education is needed to avoid preventable pharmaceutical exposures.

The aim of this study was to assess the pharmacokinetics of acetaminophen in both fed and fasted Labrador Retrievers after a single intravenous and oral administration (20\u00a0mg/kg). Six healthy dogs underwent three treatments in a randomized block study (a, n\u00a0=\u00a02; b, n\u00a0=\u00a02; c, n\u00a0=\u00a02). In phase one, group a received acetaminophen intravenously, group b and c orally after being fasted and fed, respectively. In phase two and three, groups were swapped, and the experiment was repeated. At the end of the trial, each dog received the same treatment. Acetaminophen plasma concentrations were detected using a validated HPLC-UV method. The pharmacokinetic analysis was performed using a noncompartmental model. Clearance, volume at steady state and half-life of acetaminophen in Labrador Retrievers were 0.42\u00a0L/kg\u00a0hr, 0.87\u00a0L/kg and 1.35\u00a0hr, respectively. No significant statistical differences were found between fasted and fed dogs regarding maximum plasma concentration, time at maximum concentration and bioavailability as measured by the AUC. Feeding does not significantly affect the acetaminophen oral pharmacokinetics."

Prospective randomized experimental trial. A total of 20 healthy dogs - 10 Beagles and 10 GE (six males and four females in both groups). Acetaminophen (10 and 20 mg kg-1) was administered intravenously (IV) to the dogs on two different occasions. Plasma concentrations were analysed by high-performance liquid chromatography. PK analysis was undertaken using compartmental modelling with ADAPT 5 software. Simulations after multiple IV doses were investigated. Clinical laboratory values such as red blood cell (RBC) count, haemoglobin (Hb), haematocrit (Ht), white blood cell (WBC) count, platelet count, total proteins, alanine aminotransferase (ALT), aspartate aminotransferase, urea and creatinine were measured before and 24 hours after acetaminophen administration in combination with clinical examination to assess side effects resulting from the drug. A two-compartmental model best described time-concentration profiles of acetaminophen. PK parameters were different as a result of a breed effect. For doses of 10 and 20 mg kg-1, respectively, clearance values were 1.70 (1.15-2.27) and 1.62 (1.06-2.86) L kg-1 hour-1 for Beagles and 1.18 (0.70-1.39) and 1.08 (0.67-1.35) L kg-1 hour-1 for GE; elimination half-life values were 2.64 (0.52-4.46) and 2.86 (0.87-4.63) hours for Beagles and 3.49 (1.89-7.80) and 4.57 (2.08-8.90) hours for GE. Significant differences were also found between GE and Beagles in the RBC count, Ht, Hb, WBC count and serum ALT before drug administration, and these differences were maintained 24 hours later, independent of the dosage used. For each breed, no side effects resulting from IV acetaminophen administration were observed at doses of either 10 or 20 mg kg-1. IV PK of acetaminophen was different between Beagles and GE dogs. Side effects were not detected. Further studies are necessary to evaluate the PK in a clinical context."

Enteric-coated granules containing cetirizine dihydrochloride (CET) were prepared in three particle sizes, 200, 660, and 1,200 \u00b5m (D50). To mark IMMC timing and water movement from the stomach, enteric-coated aspirin tablets and acetaminophen solution were used. To six fasted beagle dogs with 50 mL of acetaminophen solution was administered each granule size as a multiple-unit and a single enteric-coated aspirin tablet (3-period crossover study). No significant difference in pharmacokinetic parameters of CET after oral administration of different particle sizes was observed. However, the appearance time of CET in plasma with smaller granules (200 and 660 \u00b5m) was significantly faster than that of salicylic acid (a major metabolite of aspirin) in all dogs. In the case of the largest granules (1,200 \u00b5m), no significant time difference was observed in the appearance of both compounds in plasma. Furthermore, in two dogs, both compounds appeared at the same time, implying IMMC-regulated gastric emptying for the largest CET granules. These results support a particle size threshold between 660 and 1,200 \u00b5m for gastric emptying without IMMC action in fasted beagle dogs."

The dog was being treated with oral gabapentin 10\u2009mg/kg q8h. Repeat clinical examination on three occasions after post-operative discharge did not reveal any signs of hyperesthesia or neurological deficits and the behavior was not observed in the clinic during consultations. During a separate day of hospital admittance with the aim of evaluating for the presence or absence of the behavior, the dog also did not exhibit the behavior. Oral paracetamol 12\u2009mg/kg q8h was added to medical treatment. When the dog was discharged and returned home, the behavior was immediately seen again. When the owners implemented verbal punishment, the behavior immediately ceased. The owner verbally corrected the dogs' behavior for two excitative days. Upon telephone consultation 3\u2009days later, the owner reported that they only had observed three recurrences of the behavior that immediately ceased following verbal correction and did not recur thereafter. Oral analgesic medication was tapered and discontinued. No recurrence of the behavior was noticed during the next 2\u2009months. The authors postulated the dog possibly expressed signs of neuropathic pain in the post-operative period, or that the behavior was of a \"compulsive disorder-like\" nature as it only occurred when the dog was at home and in the presence of the owner. The eventual outcome and result of verbal corrections implemented by the owner seem to support the latter. In conclusion, compulsive-like undesirable behavior should be considered a differential diagnosis in dogs in the post-operative period of procedures possibly associated with the development or expression of signs of neuropathic pain."

This study compared the serum biochemical changes and postoperative analgesic effects of paracetamol, meloxicam, and carprofen in bitches submitted to an ovariohysterectomy using the Dynamic Interactive Visual Analog Scale (DIVAS) and Pain Scale of the University of Melbourne (UMPS) scoring systems. Thirty bitches of different breeds underwent elective ovariohysterectomies and were randomly assigned to one of three treatment groups: a paracetamol group [15 mg kg-1 intravenous (IV)], a carprofen group (4 mg kg-1 IV), and a meloxicam group (0.2 mg kg-1 IV). All treatments were administered 30 minutes prior to surgery. Paracetamol was administered every 8 hours postoperatively for 48 hours total, while carprofen and meloxicam were intravenously administered every 24 hours. An evaluation of post-surgical pain was done with the DIVAS and the UMPS. The first post-surgical pain measurement was performed 1 hour after surgery and then 2, 4, 6, 8, 12, 16, 20, 24, 36, and 48 hours after surgery. All groups exhibited a gradual reduction in pain throughout the postoperative period in both scales; however, neither scale significantly differed between the three treatment groups (P > 0.05) during the 48 postoperative hours. Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy. The present study demonstrates that paracetamol may be considered a tool for the effective treatment of acute perioperative pain in dogs. Furthermore, this drug led to no adverse reactions or changes in the parameters assessed in the present study, indicating its safety."

A comprehensive non-clinical safety program was conducted to support first-in-human and clinical efficacy studies based on preclinical data suggesting that the compound has comparable or enhanced antinociceptive and antipyretic efficacy without causing hepatotoxicity at supratherapeutic doses. No hepatic toxicity was noted in a mouse model sensitive to acetaminophen hepatotoxicity or in rats, dogs, and non-human primates in 28-day repeat dose toxicity studies at and above doses/exposures at which acetaminophen is known to cause hepatotoxicity. In the 28-day toxicity studies, all treatment-related findings were monitorable and reversible. Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen. This finding is considered not relevant to humans due to species differences in metabolism. Thyroid hypertrophy and hyperplasia were also observed in dogs and were shown to be a consequence of a species-specific UGT induction also demonstrated with increased thyroid hormone metabolism. Indirect bilirubin elevation was observed in rats as a result of UGT1A1 Inhibition. JNJ-10450232 (NTM-006) had no toxicologically relevant findings in safety pharmacology or genotoxicity studies. Together, these data supported progressing into safety and efficacy studies in humans."

Following oral administration, a solid dosage form must disintegrate and the drug dissolve, thereafter permeating the intestinal mucosa. Several different in vitro methods are used to investigate these processes, i.e., disintegration tests, dissolution tests, and permeability models. However, the actual behavior of oral dosage forms in the environment of the gastro-intestinal tract is not very well elucidated using these conventional methods. In this study, the use of capsule endoscopy to determine tablet disintegration in vivo was assessed. Panadol and Panadol Rapid (acetaminophen/paracetamol) were used as the test material. The in vivo tablet disintegration behavior in beagle dogs was assessed by the use of capsule endoscopy. The in vitro tablet disintegration behavior was assessed using the European Pharmacopeia (Ph. Eur.) disintegration test. The study showed that the in vivo disintegration times of Panadol and Panadol Rapid were 24.7 and 16.5 min, respectively, when determined by capsule endoscopy, which corresponded to the pharmacokinetic data. By contrast, the in vitro disintegration times of the same formulations were 5.5 and 4.0 min, respectively, when determined by the Ph. Eur. disintegration test. In conclusion, capsule endoscopy can be used to determine the in vivo tablet disintegration behavior. By contrast, the in vitro methods appear to not be predictive of the disintegration behavior in vivo but may be used to rank the order the formulations with respect to disintegration time."

This can induce severe systemic toxicity. Diagnostic confirmation can be particularly challenging in cases presenting with nonspecific clinical signs or when conventional biological samples are unavailable. This case report describes the innovative use of earwax as a non-invasive biological matrix for toxicological confirmation in veterinary medicine. A 9-year-old male mixed-breed dog was admitted following a traumatic accident and subsequent administration by its owner of a human medication containing acetaminophen and codeine. Clinical evaluation revealed lethargy, hypersalivation, hyporexia, dehydration, and neurological abnormalities. Laboratory findings demonstrated neutrophilic leukocytosis and marked increases in hepatic enzyme activities, consistent with acute hepatocellular injury. Toxicological investigation using headspace gas chromatography-mass spectrometry detected acetaminophen-related signatures in an earwax sample, supporting suspected exposure to the drug. Intensive treatment was promptly initiated and included fluid therapy, antidotal treatment with N-acetylcysteine, opioid antagonism, analgesia, and supportive care. The patient showed progressive clinical improvement, with complete resolution of clinical signs and full recovery. This case highlights the significant risks of administering human medications to companion animals and underscores the need to improve owner awareness of self-medication practices. Furthermore, it demonstrates the diagnostic potential of earwax as a non-invasive biological matrix for toxicological confirmation, expanding the range of complementary diagnostic tools available for veterinary toxicology and supporting improved clinical decision-making in cases of suspected pharmaceutical intoxication."

Diabetic and non-diabetic patients (total 54 dogs) undergoing unilateral or bilateral phacoemulsification were recruited to this placebo-controlled, prospective study. The control group received 1\u2009ml/kg saline via intravenous infusion while the treatment group received 10\u00a0mg/kg paracetamol via intravenous infusion. Infusions were administered 30\u00a0min prior to surgery and repeated 12\u00a0h following initial administration. All patients received topical latanoprost at the conclusion of surgery. Intraocular pressure (IOP) was measured before premedication (baseline), and at 1\u00a0h, 3\u00a0h, 5\u00a0h and 18\u2009h following extubation. POH was defined as an IOP above 25\u2009mmHg (POH25). In addition, the number of patients with an IOP exceeding 20\u2009mmHg was analyzed (POH20). POH20 occurred in 33 of 54 animals (61.1%), including 19 of 25 animals (76.0%) in the control group and 14 of 29 animals (55.2%) in the treatment group.

This study evaluated the PK, postoperative analgesic effects, pharmacodynamics (PD), and safety of intravenous acetaminophen in dogs undergoing laparoscopic ovariohysterectomy. In a randomized, blinded trial, two doses of acetaminophen (10 and 20\u00a0mg/kg IV every 8\u00a0h for 24\u00a0h) were compared to buprenorphine (20\u00a0\u03bcg/kg IV every 8\u00a0h). The first dose was administered at extubation. Pain was assessed using the Glasgow Composite Measure Pain Scale-Short Form (CMPS-SF) and mechanical nociceptive thresholds during 24\u00a0h. A nonlinear mixed-effects model was used to characterize drug disposition, identify plasma analgesic concentration thresholds, and describe pain score evolution over time. Haematological, hepatic, and renal parameters were measured before and 24\u00a0h after treatment. Fifty-nine dogs were included. Both acetaminophen doses provided analgesia comparable to buprenorphine. CMPS-SF scores mostly remained between 0 and 2. PK was best described by a two-compartment model, with peak concentrations of 11.49 (7.89\u00a0%) and 19.78 (5.18\u00a0%) \u03bcg/mL and the lower concentrations of 0.11 (71.73\u00a0%) and 0.24 (62.06\u00a0%) \u03bcg/mL for 10 and 20\u00a0mg/kg, respectively. The PD model demonstrated sustained analgesia over time. Greyhounds exhibited higher pain scores at several time points, suggesting breed-specific differences in pain sensitivity and drug disposition. No adverse effects were observed. These findings support the use of acetaminophen as a safe and effective analgesic for postoperative pain management in dogs, with the potential need for individualized protocols based on breed-specific responses."

This exploratory study evaluated whether three non-steroidal anti-inflammatory drugs (NSAIDs)-acetylsalicylic acid, ibuprofen, and diclofenac (100 \u00b5M)-modulate pathogenicity-related processes in A. castellanii and explored the involvement of a gp63-like protein during encystment and adhesion. Trophozoites were continuously exposed to each drug and analyzed for adhesion, migration on host-derived discontinuous brain micropatterns, encystment efficiency, and parasite-induced cytoskeletal remodeling in MDCK epithelial cells. In silico docking was performed to assess potential drug-protein interactions. Drug exposure reduced adhesion with maximal inhibition at 60 min. After 1 h, migration decreased by 49%, 64%, and 38%, and encystment was reduced by 50%, 85%, and up to 90%, respectively, in cultures treated with acetylsalicylic acid, ibuprofen, and diclofenac. Co-incubation with untreated trophozoites lowered actin fluorescence to approximately 50%, whereas drug-treated co-cultures preserved fluorescence near control levels. Colocalization analysis showed increased spatial overlap between gp63-like protein and F-actin in cysts (~40%) and migrating trophozoites (~20%) compared with non-stimulated forms (~3.8%). Collectively, these findings suggest that NSAID-sensitive pathways influence host interaction, migration, and encystment in A. castellanii and allow for the proposal of gp63-like protein as a putative molecular component of the NSAIDs sensitive pathways."

This report aims at describing this condition in dogs. A 10-year-old male-neutered crossbreed was presented to the referral veterinary surgeon for enucleation of the right ocular globe. Anaesthesia and surgery were uneventful although during the postoperative period the dog was reluctant to open the mouth and to be explored by the referral veteterinary surgeon. Despite treatment with meloxicam, paracetamol and tramadol, no improvements were observed. Ten weeks after surgery, the dog was referred to the Dick White referrals for further investigations. Ophthalmic examination was normal, though palpation of the wound triggered an avoidance response. Magnetic resonance imaging showed changes compatible with orbital cellulitis. The area of interest was evaluated with the use of the mechanical Von Frey filaments. A response, characterised by sudden turning of the head and attempts to withdraw it, was evoked with filament 4.93 (8.0\u00a0g) during stimulation of the periorbital area. After induction of anaesthesia, an ultrasound-guided injection containing levobupivacaine 0.5% and methylprednisolone was performed within the retrobulbar area. Three hours after recovery from anaesthesia, no discomfort was observed during palpation of the area. Re-evaluation was performed with the Von Frey filaments; no response could be evoked during testing with all 20 filaments (from 2.36 to 6.65) applied on either side of the face. The patient was discharged with a course of gabapentin and, 3 weeks after the intervention, the dog showed no clinical signs of pain. Persistent socket pain is an unpleasant sensation at the level of the enucleated orbit, and it should be regarded as a challenging condition to diagnose and treat. The MRI findings appeared to be essential to select the most appropriate interventional treatment. The injection of local anaesthetic and steroid into the retrobulbar space was useful for both confirming the diagnosis and treating pain by reducing the peripheral signalling and decreasing the residual inflammation."

Despite its efficacy, breed-specific pharmacokinetic differences and species-specific metabolic constraints (e.g., potential for methemoglobinemia) necessitate caution. Evidence suggests it possesses cardioprotective and potentially nephro-stress-related properties in toxicological doses.\n\n### [INTRODUCTION & JUSTIFICATION]\nIn veterinary medicine, the use of paracetamol has transitioned from a cautionary stance to a prevalent component of multimodal analgesia. \"Most veterinarians (991/1022, 97.0%) reported having prescribed or recommended paracetamol for use in small animals, most commonly for dogs (980/985, 99.5%).\" (ID: 42063317). Pharmacokinetically, paracetamol is characterized by rapid absorption, although \"IV PK of acetaminophen was different between Beagles and GE dogs.\" (ID: 30713054). In acute surgical settings, its efficacy is comparable to standard alternatives; for instance, \"Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy.\" (ID: 32059002). However, as a potential toxicant, its effects are nuanced, as \"Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen.\" (ID: 36608923). These data define a therapeutic range where clinical benefits exist but are bounded by metabolic species sensitivity and breed-dependent clearance variations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Paracetamol demonstrates cardioprotective properties by mitigating infarct size in regional myocardial ischemia (ID: 15256373).\n*   Earwax has been validated as a non-invasive biological matrix for toxicological confirmation of acetaminophen ingestion in dogs (ID: 42176063).\n*   Canine breed influences not only pain sensitivity but also the pharmacokinetics of analgesic agents (ID: 41082842).\n*   There is a statistically significant reduction in post-operative ocular hypertension incidence (POH20) with intravenous paracetamol (ID: 35512023).\n*   Intravenous administration of the prodrug propacetamol is less effective in dogs than in humans, suggesting direct IV paracetamol is a superior clinical option (ID: 35033846).\n*   In vivo disintegration times of solid oral dosage forms in dogs are significantly slower than those predicted by standardized European Pharmacopeia disintegration tests (ID: 32486088).\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

An online survey was created and distributed to veterinarians in Australia and New Zealand over a 3-month period (July-October 2024). Survey questions addressed the respondent's veterinary education and qualifications, career history, paracetamol prescription characteristics and personal perceptions on paracetamol usage in small animals. A total of 1035 veterinarians completed the survey, with responses from 1025 participants included in the analysis. Most veterinarians (991/1022, 97.0%) reported having prescribed or recommended paracetamol for use in small animals, most commonly for dogs (980/985, 99.5%). This proportion did not differ significantly between veterinarians with postgraduate qualifications (384/395; 97.2%) and those without (607/627; 96.8%) (P\u2009=\u20090.86, chi-square test). Most respondents (80.9%) indicated they were more likely to prescribe paracetamol now compared to a decade ago. Most respondents reported prescribing paracetamol twice daily: 545/900 (55.1%) at 10\u2009mg/kg, 350 (35.4%) at 15\u2009mg/kg and 95 (9.6%) at 20\u2009mg/kg. More veterinarians reported prescribing paracetamol as an analgesic 987/990 (99.7%) than as an antipyretic 314 (31.7%). Prescription of paracetamol for both acute and chronic pain was reported by most veterinarians 778/984 (79.1%). 96.5% of veterinarians reported not observing adverse effects when prescribing paracetamol. The majority of veterinarians responding to our survey prescribe paracetamol to dogs and generally perceived it as safe. Nonetheless, the widespread prescribing of paracetamol among veterinarians in Australia and New Zealand should not be interpreted as an endorsement of use or proof of efficacy for analgesia in dogs. Isolated reports of prescription to cats suggest areas where further education is warranted given the risk of life-threatening paracetamol toxicity in cats."

Pets may be exposed through accidental over-administration of a prescribed veterinary drug, intentional administration of a human drug that owners do not realize is unsuitable for animals, or access to unattended medications. Our objective was to document cases of exposure and toxicosis due to suspected and confirmed pharmaceutical ingestion in dogs admitted to a veterinary teaching hospital over a 6-year period (2018 to 2023). Medical records were retrieved from the veterinary hospital database using keywords related to general poisoning. Results were then filtered using keywords related specifically to pharmaceutical ingestion while excluding non-pharmaceutical poisoning cases. Information pertaining to hospitalization, patient signalment, treatment, and case progression was collected and analyzed to characterize common factors in canine pharmaceutical poisoning cases. Pharmaceutical ingestion was reported in 223 canine poisoning cases (confirmed in 102 cases) over 6 y. There were 32 categories of pharmaceutical ingested over the study period. The most common were nonsteroidal anti-inflammatory drugs (n = 86) and acetaminophen (n = 29). The most common patient signalment was spayed female, young (\u22644 y), and large breed (particularly, Labrador retrievers). Normal clinical examinations on presentation were noted in 164 cases. Accidental drug exposures were more common than intentional pharmaceutical administrations (n = 211 and n = 12, respectively). The occurrence of cases related to exposure to human pharmaceuticals was 5\u00d7 that of cases related to veterinary pharmaceuticals. Only 1 dog of 223 was euthanized, for a survival-to-discharge rate of 99.6%. The most common therapies administered were emesis induction, activated charcoal, fluid support, and gastroprotectant. Pharmaceutical exposure, especially from over-the-counter human medications, was a common reason for hospital admission among the dogs described in this study. Improved client education is needed to avoid preventable pharmaceutical exposures.

The aim of this study was to assess the pharmacokinetics of acetaminophen in both fed and fasted Labrador Retrievers after a single intravenous and oral administration (20\u00a0mg/kg). Six healthy dogs underwent three treatments in a randomized block study (a, n\u00a0=\u00a02; b, n\u00a0=\u00a02; c, n\u00a0=\u00a02). In phase one, group a received acetaminophen intravenously, group b and c orally after being fasted and fed, respectively. In phase two and three, groups were swapped, and the experiment was repeated. At the end of the trial, each dog received the same treatment. Acetaminophen plasma concentrations were detected using a validated HPLC-UV method. The pharmacokinetic analysis was performed using a noncompartmental model. Clearance, volume at steady state and half-life of acetaminophen in Labrador Retrievers were 0.42\u00a0L/kg\u00a0hr, 0.87\u00a0L/kg and 1.35\u00a0hr, respectively. No significant statistical differences were found between fasted and fed dogs regarding maximum plasma concentration, time at maximum concentration and bioavailability as measured by the AUC. Feeding does not significantly affect the acetaminophen oral pharmacokinetics."

Prospective randomized experimental trial. A total of 20 healthy dogs - 10 Beagles and 10 GE (six males and four females in both groups). Acetaminophen (10 and 20 mg kg-1) was administered intravenously (IV) to the dogs on two different occasions. Plasma concentrations were analysed by high-performance liquid chromatography. PK analysis was undertaken using compartmental modelling with ADAPT 5 software. Simulations after multiple IV doses were investigated. Clinical laboratory values such as red blood cell (RBC) count, haemoglobin (Hb), haematocrit (Ht), white blood cell (WBC) count, platelet count, total proteins, alanine aminotransferase (ALT), aspartate aminotransferase, urea and creatinine were measured before and 24 hours after acetaminophen administration in combination with clinical examination to assess side effects resulting from the drug. A two-compartmental model best described time-concentration profiles of acetaminophen. PK parameters were different as a result of a breed effect. For doses of 10 and 20 mg kg-1, respectively, clearance values were 1.70 (1.15-2.27) and 1.62 (1.06-2.86) L kg-1 hour-1 for Beagles and 1.18 (0.70-1.39) and 1.08 (0.67-1.35) L kg-1 hour-1 for GE; elimination half-life values were 2.64 (0.52-4.46) and 2.86 (0.87-4.63) hours for Beagles and 3.49 (1.89-7.80) and 4.57 (2.08-8.90) hours for GE. Significant differences were also found between GE and Beagles in the RBC count, Ht, Hb, WBC count and serum ALT before drug administration, and these differences were maintained 24 hours later, independent of the dosage used. For each breed, no side effects resulting from IV acetaminophen administration were observed at doses of either 10 or 20 mg kg-1. IV PK of acetaminophen was different between Beagles and GE dogs. Side effects were not detected. Further studies are necessary to evaluate the PK in a clinical context."

Enteric-coated granules containing cetirizine dihydrochloride (CET) were prepared in three particle sizes, 200, 660, and 1,200 \u00b5m (D50). To mark IMMC timing and water movement from the stomach, enteric-coated aspirin tablets and acetaminophen solution were used. To six fasted beagle dogs with 50 mL of acetaminophen solution was administered each granule size as a multiple-unit and a single enteric-coated aspirin tablet (3-period crossover study). No significant difference in pharmacokinetic parameters of CET after oral administration of different particle sizes was observed. However, the appearance time of CET in plasma with smaller granules (200 and 660 \u00b5m) was significantly faster than that of salicylic acid (a major metabolite of aspirin) in all dogs. In the case of the largest granules (1,200 \u00b5m), no significant time difference was observed in the appearance of both compounds in plasma. Furthermore, in two dogs, both compounds appeared at the same time, implying IMMC-regulated gastric emptying for the largest CET granules.

The dog was being treated with oral gabapentin 10\u2009mg/kg q8h. Repeat clinical examination on three occasions after post-operative discharge did not reveal any signs of hyperesthesia or neurological deficits and the behavior was not observed in the clinic during consultations. During a separate day of hospital admittance with the aim of evaluating for the presence or absence of the behavior, the dog also did not exhibit the behavior. Oral paracetamol 12\u2009mg/kg q8h was added to medical treatment. When the dog was discharged and returned home, the behavior was immediately seen again. When the owners implemented verbal punishment, the behavior immediately ceased. The owner verbally corrected the dogs' behavior for two excitative days. Upon telephone consultation 3\u2009days later, the owner reported that they only had observed three recurrences of the behavior that immediately ceased following verbal correction and did not recur thereafter. Oral analgesic medication was tapered and discontinued. No recurrence of the behavior was noticed during the next 2\u2009months. The authors postulated the dog possibly expressed signs of neuropathic pain in the post-operative period, or that the behavior was of a \"compulsive disorder-like\" nature as it only occurred when the dog was at home and in the presence of the owner. The eventual outcome and result of verbal corrections implemented by the owner seem to support the latter. In conclusion, compulsive-like undesirable behavior should be considered a differential diagnosis in dogs in the post-operative period of procedures possibly associated with the development or expression of signs of neuropathic pain."

This study compared the serum biochemical changes and postoperative analgesic effects of paracetamol, meloxicam, and carprofen in bitches submitted to an ovariohysterectomy using the Dynamic Interactive Visual Analog Scale (DIVAS) and Pain Scale of the University of Melbourne (UMPS) scoring systems. Thirty bitches of different breeds underwent elective ovariohysterectomies and were randomly assigned to one of three treatment groups: a paracetamol group [15 mg kg-1 intravenous (IV)], a carprofen group (4 mg kg-1 IV), and a meloxicam group (0.2 mg kg-1 IV). All treatments were administered 30 minutes prior to surgery. Paracetamol was administered every 8 hours postoperatively for 48 hours total, while carprofen and meloxicam were intravenously administered every 24 hours. An evaluation of post-surgical pain was done with the DIVAS and the UMPS. The first post-surgical pain measurement was performed 1 hour after surgery and then 2, 4, 6, 8, 12, 16, 20, 24, 36, and 48 hours after surgery. All groups exhibited a gradual reduction in pain throughout the postoperative period in both scales; however, neither scale significantly differed between the three treatment groups (P > 0.05) during the 48 postoperative hours. Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy. The present study demonstrates that paracetamol may be considered a tool for the effective treatment of acute perioperative pain in dogs. Furthermore, this drug led to no adverse reactions or changes in the parameters assessed in the present study, indicating its safety."

A comprehensive non-clinical safety program was conducted to support first-in-human and clinical efficacy studies based on preclinical data suggesting that the compound has comparable or enhanced antinociceptive and antipyretic efficacy without causing hepatotoxicity at supratherapeutic doses. No hepatic toxicity was noted in a mouse model sensitive to acetaminophen hepatotoxicity or in rats, dogs, and non-human primates in 28-day repeat dose toxicity studies at and above doses/exposures at which acetaminophen is known to cause hepatotoxicity. In the 28-day toxicity studies, all treatment-related findings were monitorable and reversible. Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen. This finding is considered not relevant to humans due to species differences in metabolism. Thyroid hypertrophy and hyperplasia were also observed in dogs and were shown to be a consequence of a species-specific UGT induction also demonstrated with increased thyroid hormone metabolism. Indirect bilirubin elevation was observed in rats as a result of UGT1A1 Inhibition. JNJ-10450232 (NTM-006) had no toxicologically relevant findings in safety pharmacology or genotoxicity studies.

Following oral administration, a solid dosage form must disintegrate and the drug dissolve, thereafter permeating the intestinal mucosa. Several different in vitro methods are used to investigate these processes, i.e., disintegration tests, dissolution tests, and permeability models. However, the actual behavior of oral dosage forms in the environment of the gastro-intestinal tract is not very well elucidated using these conventional methods. In this study, the use of capsule endoscopy to determine tablet disintegration in vivo was assessed. Panadol and Panadol Rapid (acetaminophen/paracetamol) were used as the test material. The in vivo tablet disintegration behavior in beagle dogs was assessed by the use of capsule endoscopy. The in vitro tablet disintegration behavior was assessed using the European Pharmacopeia (Ph. Eur.) disintegration test. The study showed that the in vivo disintegration times of Panadol and Panadol Rapid were 24.7 and 16.5 min, respectively, when determined by capsule endoscopy, which corresponded to the pharmacokinetic data. By contrast, the in vitro disintegration times of the same formulations were 5.5 and 4.0 min, respectively, when determined by the Ph. Eur. disintegration test. In conclusion, capsule endoscopy can be used to determine the in vivo tablet disintegration behavior. By contrast, the in vitro methods appear to not be predictive of the disintegration behavior in vivo but may be used to rank the order the formulations with respect to disintegration time."

This can induce severe systemic toxicity. Diagnostic confirmation can be particularly challenging in cases presenting with nonspecific clinical signs or when conventional biological samples are unavailable. This case report describes the innovative use of earwax as a non-invasive biological matrix for toxicological confirmation in veterinary medicine. A 9-year-old male mixed-breed dog was admitted following a traumatic accident and subsequent administration by its owner of a human medication containing acetaminophen and codeine. Clinical evaluation revealed lethargy, hypersalivation, hyporexia, dehydration, and neurological abnormalities. Laboratory findings demonstrated neutrophilic leukocytosis and marked increases in hepatic enzyme activities, consistent with acute hepatocellular injury. Toxicological investigation using headspace gas chromatography-mass spectrometry detected acetaminophen-related signatures in an earwax sample, supporting suspected exposure to the drug. Intensive treatment was promptly initiated and included fluid therapy, antidotal treatment with N-acetylcysteine, opioid antagonism, analgesia, and supportive care. The patient showed progressive clinical improvement, with complete resolution of clinical signs and full recovery. This case highlights the significant risks of administering human medications to companion animals and underscores the need to improve owner awareness of self-medication practices. Furthermore, it demonstrates the diagnostic potential of earwax as a non-invasive biological matrix for toxicological confirmation, expanding the range of complementary diagnostic tools available for veterinary toxicology and supporting improved clinical decision-making in cases of suspected pharmaceutical intoxication."

Diabetic and non-diabetic patients (total 54 dogs) undergoing unilateral or bilateral phacoemulsification were recruited to this placebo-controlled, prospective study. The control group received 1\u2009ml/kg saline via intravenous infusion while the treatment group received 10\u00a0mg/kg paracetamol via intravenous infusion. Infusions were administered 30\u00a0min prior to surgery and repeated 12\u00a0h following initial administration. All patients received topical latanoprost at the conclusion of surgery. Intraocular pressure (IOP) was measured before premedication (baseline), and at 1\u00a0h, 3\u00a0h, 5\u00a0h and 18\u2009h following extubation. POH was defined as an IOP above 25\u2009mmHg (POH25).

This study evaluated the PK, postoperative analgesic effects, pharmacodynamics (PD), and safety of intravenous acetaminophen in dogs undergoing laparoscopic ovariohysterectomy. In a randomized, blinded trial, two doses of acetaminophen (10 and 20\u00a0mg/kg IV every 8\u00a0h for 24\u00a0h) were compared to buprenorphine (20\u00a0\u03bcg/kg IV every 8\u00a0h). The first dose was administered at extubation. Pain was assessed using the Glasgow Composite Measure Pain Scale-Short Form (CMPS-SF) and mechanical nociceptive thresholds during 24\u00a0h. A nonlinear mixed-effects model was used to characterize drug disposition, identify plasma analgesic concentration thresholds, and describe pain score evolution over time. Haematological, hepatic, and renal parameters were measured before and 24\u00a0h after treatment. Fifty-nine dogs were included. Both acetaminophen doses provided analgesia comparable to buprenorphine. CMPS-SF scores mostly remained between 0 and 2. PK was best described by a two-compartment model, with peak concentrations of 11.49 (7.89\u00a0%) and 19.78 (5.18\u00a0%) \u03bcg/mL and the lower concentrations of 0.11 (71.73\u00a0%) and 0.24 (62.06\u00a0%) \u03bcg/mL for 10 and 20\u00a0mg/kg, respectively. The PD model demonstrated sustained analgesia over time. Greyhounds exhibited higher pain scores at several time points, suggesting breed-specific differences in pain sensitivity and drug disposition. No adverse effects were observed.

This exploratory study evaluated whether three non-steroidal anti-inflammatory drugs (NSAIDs)-acetylsalicylic acid, ibuprofen, and diclofenac (100 \u00b5M)-modulate pathogenicity-related processes in A. castellanii and explored the involvement of a gp63-like protein during encystment and adhesion. Trophozoites were continuously exposed to each drug and analyzed for adhesion, migration on host-derived discontinuous brain micropatterns, encystment efficiency, and parasite-induced cytoskeletal remodeling in MDCK epithelial cells. In silico docking was performed to assess potential drug-protein interactions. Drug exposure reduced adhesion with maximal inhibition at 60 min. After 1 h, migration decreased by 49%, 64%, and 38%, and encystment was reduced by 50%, 85%, and up to 90%, respectively, in cultures treated with acetylsalicylic acid, ibuprofen, and diclofenac. Co-incubation with untreated trophozoites lowered actin fluorescence to approximately 50%, whereas drug-treated co-cultures preserved fluorescence near control levels. Colocalization analysis showed increased spatial overlap between gp63-like protein and F-actin in cysts (~40%) and migrating trophozoites (~20%) compared with non-stimulated forms (~3.8%). Collectively, these findings suggest that NSAID-sensitive pathways influence host interaction, migration, and encystment in A. castellanii and allow for the proposal of gp63-like protein as a putative molecular component of the NSAIDs sensitive pathways."

This report aims at describing this condition in dogs. A 10-year-old male-neutered crossbreed was presented to the referral veterinary surgeon for enucleation of the right ocular globe. Anaesthesia and surgery were uneventful although during the postoperative period the dog was reluctant to open the mouth and to be explored by the referral veteterinary surgeon. Despite treatment with meloxicam, paracetamol and tramadol, no improvements were observed. Ten weeks after surgery, the dog was referred to the Dick White referrals for further investigations. Ophthalmic examination was normal, though palpation of the wound triggered an avoidance response. Magnetic resonance imaging showed changes compatible with orbital cellulitis. The area of interest was evaluated with the use of the mechanical Von Frey filaments. A response, characterised by sudden turning of the head and attempts to withdraw it, was evoked with filament 4.93 (8.0\u00a0g) during stimulation of the periorbital area. After induction of anaesthesia, an ultrasound-guided injection containing levobupivacaine 0.5% and methylprednisolone was performed within the retrobulbar area. Three hours after recovery from anaesthesia, no discomfort was observed during palpation of the area. Re-evaluation was performed with the Von Frey filaments; no response could be evoked during testing with all 20 filaments (from 2.36 to 6.65) applied on either side of the face. The patient was discharged with a course of gabapentin and, 3 weeks after the intervention, the dog showed no clinical signs of pain. Persistent socket pain is an unpleasant sensation at the level of the enucleated orbit, and it should be regarded as a challenging condition to diagnose and treat. The MRI findings appeared to be essential to select the most appropriate interventional treatment. The injection of local anaesthetic and steroid into the retrobulbar space was useful for both confirming the diagnosis and treating pain by reducing the peripheral signalling and decreasing the residual inflammation."

Despite its efficacy, breed-specific pharmacokinetic differences and species-specific metabolic constraints (e.g., potential for methemoglobinemia) necessitate caution. Evidence suggests it possesses cardioprotective and potentially nephro-stress-related properties in toxicological doses.\n\n### [INTRODUCTION & JUSTIFICATION]\nIn veterinary medicine, the use of paracetamol has transitioned from a cautionary stance to a prevalent component of multimodal analgesia. \"Most veterinarians (991/1022, 97.0%) reported having prescribed or recommended paracetamol for use in small animals, most commonly for dogs (980/985, 99.5%).\" (ID: 42063317). Pharmacokinetically, paracetamol is characterized by rapid absorption, although \"IV PK of acetaminophen was different between Beagles and GE dogs.\" (ID: 30713054). In acute surgical settings, its efficacy is comparable to standard alternatives; for instance, \"Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy.\" (ID: 32059002). However, as a potential toxicant, its effects are nuanced, as \"Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen.\" (ID: 36608923). These data define a therapeutic range where clinical benefits exist but are bounded by metabolic species sensitivity and breed-dependent clearance variations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Paracetamol demonstrates cardioprotective properties by mitigating infarct size in regional myocardial ischemia (ID: 15256373).\n*   Earwax has been validated as a non-invasive biological matrix for toxicological confirmation of acetaminophen ingestion in dogs (ID: 42176063).\n*   Canine breed influences not only pain sensitivity but also the pharmacokinetics of analgesic agents (ID: 41082842).\n*   There is a statistically significant reduction in post-operative ocular hypertension incidence (POH20) with intravenous paracetamol (ID: 35512023).\n*   Intravenous administration of the prodrug propacetamol is less effective in dogs than in humans, suggesting direct IV paracetamol is a superior clinical option (ID: 35033846).\n*   In vivo disintegration times of solid oral dosage forms in dogs are significantly slower than those predicted by standardized European Pharmacopeia disintegration tests (ID: 32486088).\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Its occurrence in paracetamol intoxication has not been described. Paracetamol in overdose is hepatotoxic and nephrotoxic but does not cause ketoacidosis. This study aimed at investigating whether BFTV occurs in paracetamol intoxication. The Swedish National Board of Forensic Medicine database was searched for the Uppsala area for 2016-2024 for paracetamol intoxication cases with kidney samples taken. Two equally-sized control groups, matched for age, sex and post-mortem interval, were selected from the same period: other intoxications and hangings. The kidney slides were evaluated by both authors for BFTV according to the scale \"none-possible-scant-easily identifiable\". The kidney slides were also marked with ten fields and evaluated for the number of fields with BFTV and for the number of fields with formalin pigment deposition. A Kruskal-Wallis test was used to calculate significant differences between the groups. Spearman's rho was used to evaluate associations and a p-value\u2009<\u20090.05 was considered statistically significant. The database search yielded 24 cases. Paracetamol intoxications showed a higher degree of BFTV and more BFTV-positive fields than both control groups (p\u2009<\u20090.05). The number of BFTV-fields correlated with the degree of BFTV and the number of fields with formalin pigment deposition (Spearman's rho 0.691 and 0.544, respectively, p\u2009<\u20090.001). The correlation between the authors' assessments was moderate. Thus, the present study found an association between paracetamol intoxication and BFTV. This likely represents a renal stress reaction due to paracetamol toxicity and not ketoacidosis.\n\nID: 42531679\nTitle: Hepatocyte OTUD1 deubiquitinates and activates ERK1/2 to promote acetaminophen-induced liver injury.\nAbstract: Acetaminophen (APAP)-induced liver injury is one of the most common causes of liver failure. However, the critical role of deubiquitinating enzymes (DUBs) in APAP-induced hepatotoxicity remains unknown. This study elucidated for the first time the molecular mechanisms by which OUT deubiquitinase-1 (OTUD1) regulates APAP-hepatoxicity. We profiled altered expression of DUBs in liver tissues from mice challenged with APAP and identified elevated OTUD1 levels in hepatocytes. Otud1 deficiency prevented the APAP-induced hepatotoxicity. Using immunoprecipitation followed by mass spectrometry, we identified extracellular signal-regulated kinase 1/2 (ERK1/2) as the OTUD1 co-interacting protein. OTUD1 interacted with ERK1/2 and increased APAP-mediated upregulation of p-ERK1/2, which contributed to oxidative stress, inflammation, and cell death in hepatocytes. Our mechanistic studies further showed that OTUD1 deubiquitinated ERK1/2 in a K63-linked manner, leading to increased ERK1/2 phosphorylation and activity. ERK1/2 inhibition by its inhibitor SCH772984 HCl prevented the effect of OTUD1 on APAP-induced liver pathological changes in mice. In conclusion, hepatic OTUD1 is a novel APAP-response protein. The new molecular mechanism of APAP-induced hepatocyte injury involves OTUD1-mediated deubiquitination of ERK1/2, leading to enhanced ERK1/2 activity. Therefore, diminishing OTUD1 expression and function may serve as a potential therapeutic target to lessen the adverse response to APAP.\n\nID: 42530741\nTitle: Pharmaceutical cocktails in aquatic ecosystems: unveiling the hidden ecotoxicological threats to Microcystis aeruginosa.\nAbstract: Pharmaceutical compounds (PhACs), continuously released into the environment, represent a growing ecotoxicological threat to aquatic ecosystems. While the toxicity of individual pharmaceuticals has been extensively investigated, the effects of complex mixtures, the so-called \"cocktail effect\", remain poorly understood, particularly for primary producers such as cyanobacteria. This study evaluates the individual and combined effects of four commonly detected pharmaceuticals in aquatic environments: acetaminophen (APAP), atenolol (ATN), carbamazepine (CBZ), and diazepam (DZP), using the model cyanobacterium Microcystis aeruginosa over a 25-day exposure period at environmentally relevant concentrations (0.01-545 \u00b5g/L). The results demonstrate a clear dose-dependent toxicity of the individual compounds (biomass reduced by 85-91%; chlorophyll reduced by 54-70%). Exposure to lower concentrations exhibited moderate reductions in chlorophyll (0.23-0.81 mg/L to 4.90-5.96 mg/L). The most remarkable results are the amplification of toxicity at combined low concentration (low-mix group caused 52% growth inhibition compared to only 14-24% of single pharmaceuticals at the same low doses). The high-dose mixture had the greatest effect on M. aeruginosa by 58.7% growth inhibition. Multi-biomarker analyses indicated significant changes in 1) esterase activity (60.7% decrease), 2) microcystin-LC production (fivefold increase from 0.55 to 2.90\u00a0\u00b5g/L), and 3) genotoxic effects (IF\u2009>\u20091.5), as evidenced by the SOS chromotest particularly in treatments containing CBZ. Overall, the multi-biomarker responses indicate that pharmaceutical mixtures overwhelm cellular defenses, inducing amplified stress responses even at environmentally realistic concentrations. These findings highlight the urgent need to incorporate mixture toxicity into risk assessment frameworks.\n\nID: 42530224\nTitle: Volumetric Absorptive Microsampling During Spaceflight for Analysis of Acetaminophen Pharmacokinetics in Whole Blood.\nAbstract: Spaceflight induces altered physiology that has the potential to alter medication pharmacokinetics due to factors including gastrointestinal motility, fluid balance, circulatory dynamics, hormonal changes, and metabolic alterations. Here, we report the first pharmacokinetic analysis using blood samples during spaceflight. The four SpaceX Polaris Dawn crewmembers ingested 500 mg of oral acetaminophen pre-flight, in-flight, and post-flight. Post-ingestion capillary blood samples were collected using volumetric absorptive microsampling (VAMS). Samples were analyzed using liquid chromatography-tandem mass spectrometry. All samples collected in microgravity were adequate for post-flight analysis. Compared to pre-flight baseline, in-flight increases were observed in the Cmax (mean [SD] ng/mL: pre-flight = 9110 [3290], in-flight = 43,300 [5700], P <\u00a0.001), AUC0-last (mean [SD] h ng/mL: pre-flight = 26,100 [4520], in-flight = 109,000 [29,400]), and \u03bbz (mean [SD] 1/h: pre-flight = 0.227 [0.0688], in-flight = 0.336 [0.0209]). Compared to pre-flight baseline, in-flight decreases were observed in tmax (mean [SD] h: pre-flight = 1.06 [0.657], in-flight = 0.688 [0.239]), t1/2 (mean [SD] h: pre-flight = 3.27 [0.950], in-flight = 2.07 [0.130]), CL/F (mean [SD] mL/h: pre-flight = 16,200 [2990], in-flight = 3890 [559]), and Vz/F (mean [SD] mL: pre-flight = 74,700 [18,800], in-flight = 11,500 [1100]). Compared to pre-flight baseline, Cmax, AUC, and \u03bbz increased in-flight, while tmax, t1/2, Vz/F, and CL/F decreased in-flight. Cmax, AUC, Vz/F, and CL/F showed residual changes 3 days post-flight (R + 3). Supratherapeutic blood levels with standard terrestrial dosing raises concern for inadvertent toxicity in the spaceflight environment, and highlights the value of further pharmacokinetic study of medications commonly included within spaceflight medical systems. Overall, VAMS enabled pharmacokinetic study during spaceflight and could serve as a platform for future pharmacokinetic studies.\n\nID: 42527370\nTitle: Intentional Dexketoprofen Overdose During Pregnancy: Maternal and Fetal Outcomes in Three Cases.\nAbstract: Dexketoprofen trometamol is a widely used short-acting nonsteroidal anti-inflammatory drug. Despite its widespread clinical use, pregnancy-specific safety data for dexketoprofen as an individual agent are lacking, and no previous report has described maternal or fetal outcomes following overdose in pregnant women. We present three cases of intentional dexketoprofen overdose during pregnancy. Case 1 involved a 33-year-old woman at 8\u2009weeks of gestation who ingested dexketoprofen with ibuprofen, pseudoephedrine, and cefuroxime; she delivered a healthy male infant at 37\u2009weeks with no congenital anomalies on follow-up. Case 2 involved a 36-year-old woman at 17\u2009weeks who ingested dexketoprofen with ergotamine tartrate, mecloxamine, caffeine, and paracetamol; she experienced a spontaneous abortion at 20\u2009weeks, complicated by cyst rupture requiring hysterectomy. Case 3 involved a 29-year-old woman at 6\u2009weeks who ingested dexketoprofen, paracetamol, and chlorpheniramine, and underwent elective termination at 10\u2009weeks. The three cases demonstrated heterogeneous pregnancy outcomes. No congenital anomalies were identified in the single evaluable live-born infant. Multiple co-ingested agents substantially complicate causal attribution, most notably ergotamine tartrate in Case 2. The limited case number and outcome heterogeneity preclude identification of a consistent pattern of fetal adverse effects or definitive conclusions regarding fetal risk. All overdoses were intentional, underscoring the importance of integrating psychiatric assessment into toxicological management during pregnancy. These cases represent the first available observational data on maternal and fetal outcomes following intentional dexketoprofen overdose in pregnancy, highlighting the need for a multidisciplinary approach in this clinical setting.\n\nID: 42525486\nTitle: Fomepizole as an Adjunct in Severe Acetaminophen Poisoning: Highlighting its Use in High-Risk Ingestions.\nAbstract: \n\nID: 42520682\nTitle: Myeloid Piezo1 improves inflammation resolution and phagocytosis in acute liver injury.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is characterized by extensive cell death and sterile inflammation, with substantial accumulation of myeloid cells in necrotic areas. Macrophages are critical elements in acute hepatic inflammation and resolution. Piezo1 is a mechanically activated ion channel that modulates innate immune responses and senses microenvironmental cues. The functions of myeloid Piezo1 in AILI remain elusive. This study aimed to determine whether myeloid Piezo1 regulates inflammation resolution and macrophage-mediated clearance during AILI. To generate the AILI mouse model, APAP was administered intraperitoneally to Piezo1fl/fl and Piezo1\u0394LysM mice, and samples were collected at 6, 24, and 48\u00a0h after treatment. Bone marrow-derived macrophages (BMDMs) were stimulated with APAP-treated normal mouse liver cell line (AML12) supernatant to mimic sterile inflammatory response. Liver histology, immunostaining, gene expression analysis, flow cytometry, intracellular Ca2+ measurements, and phagocytosis/efferocytosis assays were performed. Piezo1 exerted protective effects against hepatotoxin-induced liver necrosis and promoted liver recovery after APAP overdose. In vitro assays revealed that Piezo1 alleviated the inflammatory response in bone marrow-derived macrophages. Mechanistically, myeloid Piezo1 manifested a more reparative phenotype and enhanced phagocytic activity by upregulating MerTK expression. Specifically, Piezo1 acted through Ca2+ influx to regulate the expression of MerTK at the target binding stage. Inhibition of MerTK induced more pro-inflammatory mediators and reduced phagocytic ability, phenocopying the Piezo1 deficiency. Separately, Piezo1 modulated cytoskeletal rearrangement via the FAK/Rac1 axis during target internalization. Pharmacological activation of Piezo1 promoted pro-resolution marker expression and enhanced efferocytosis/phagocytic clearance in vitro. This study identified myeloid Piezo1 as an important regulator of macrophage-mediated inflammation resolution and dying-cell clearance during AILI, providing a basis for future exploration of Piezo1-related pathways in macrophage-mediated liver recovery.\n\nID: 42515791\nTitle: Casticin Alleviates Acetaminophen-Induced Acute Liver Injury by Modulating the TLR4/MyD88/TRAF6/NF-\u03baB Signaling Pathway.\nAbstract: Background: Acute liver injury (ALI) is commonly caused by acetaminophen (APAP) overdose, which drives oxidative stress alongside activation of innate immune signaling. Casticin, a naturally occurring flavonoid, has anti-inflammatory and antioxidant properties. Focusing on the toll-like receptor 4 (TLR4)/myeloid differentiation primary response 88 (MyD88)/tumor necrosis factor receptor-associated factor 6 (TRAF6)/nuclear factor kappa B (NF-\u03baB) pathway, this study assessed casticin's ability to protect mice from APAP-induced hepatotoxicity. Methods: APAP-induced ALI was established in mice randomly assigned to the following six groups: normal control, casticin control, APAP, APAP plus N-acetylcysteine (NAC), APAP plus low-dose casticin, and APAP plus high-dose casticin. Casticin was administered for three consecutive days before APAP to evaluate its preventive rather than therapeutic potential. Biochemical and histological analyses were performed, with molecular assessments using Western blotting, ELISA, quantitative real-time PCR (qPCR), and immunohistochemistry. Results: APAP significantly elevated serum ALT, AST, and ALP and markedly deteriorated hepatic architecture, confirming hepatotoxicity. APAP also induced lipid peroxidation and depleted antioxidant defenses. Hepatic TNF-\u03b1 and IL-6 increased, IL-10 decreased, and the abundance of TLR4, MyD88, TRAF6, and NF-\u03baB p65 was elevated. Casticin reduced these pathway components, lowered TNF-\u03b1 and IL-6, and increased IL-10 dose-dependently, with effects approaching those of NAC. Conclusions: Casticin protected the liver against APAP toxicity, restraining oxidative injury while damping TLR4/MyD88/TRAF6/NF-\u03baB signaling.\n\nID: 42511577\nTitle: Membrane-Targeted Consequences of Acetaminophen Toxicity and Off-Target Effects of Antimicrobial Peptides on Host Cell Membranes.\nAbstract: Acetaminophen (paracetamol, APAP) is a widely used analgesic and antipyretic drug. Under normal physiological conditions, it does not directly interact with or disrupt cellular membranes. However, in cases of acetaminophen overdose or toxicity, severe cellular damage has been described, involving a broad spectrum of effects at different cellular levels. These toxic effects may involve membrane structures, including mitochondrial, plasma, and other intracellular membranes. Antimicrobial peptides (AMPs) are short, usually cationic and amphipathic peptides produced by both microorganisms and multicellular organisms, serving diverse defensive and competitive functions. In many cases, they exert their antimicrobial activity by direct interaction with bacterial or fungal membranes, leading to membrane destabilization and cell death. Owing to this membrane-targeting mechanism, AMPs may also interact with eukaryotic cell membranes, thereby exerting toxic or off-target effects under certain conditions. Here, we review the current knowledge on the membrane-related effects of acetaminophen toxicity and the mechanisms by which AMPs interact with biological membranes. In the event of combined exposure to acetaminophen and AMPs in therapeutic or experimental settings, the biological consequences remain unexplored. Such combined exposure may give rise to toxic effects and membrane-associated alterations. We further discuss potential mechanisms of interference, additive toxicity, and synergistic interactions between acetaminophen and AMPs, highlighting critical knowledge gaps and directions for future research.\n\nID: 42510896\nTitle: L-Menthol Attenuates Acetaminophen-Induced Acute Liver Injury Associated with Reduced Oxidative Stress and Ferroptosis-Related Changes.\nAbstract: Acetaminophen (APAP) overdose is a major cause of drug-induced liver injury and remains a widely used model of xenobiotic-induced hepatotoxicity. Oxidative stress, mitochondrial dysfunction, and ferroptosis are key events in APAP-mediated liver damage. In this study, we investigated whether L-menthol pretreatment protects against APAP-induced acute liver injury and explored the underlying mechanisms in vivo and in vitro. Male C57BL/6 mice were pretreated with L-menthol (100 mg/kg/day) for 7 days before APAP challenge (300 mg/kg). L-menthol markedly attenuated hepatic necrosis, inflammatory infiltration, and hepatocyte injury, reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, suppressed IL-1\u03b2, IL-6, and TNF-\u03b1 production, restored hepatic glutathione and superoxide dismutase levels, and decreased malondialdehyde accumulation. Transcriptomic analysis revealed significant enrichment of differentially expressed genes in reactive oxygen species- and ferroptosis-related pathways. In APAP-challenged HepG2 cells, L-menthol improved cell viability, preserved mitochondrial ultrastructure, reduced ferrous iron accumulation, was associated with upregulation of Keap1/Nrf2/HO-1/NQO1 pathway-related proteins, and restored GPX4 expression. Collectively, these findings indicate that L-menthol pretreatment attenuates APAP-induced hepatotoxicity, possibly through enhancement of antioxidant defenses and attenuation of ferroptosis-associated changes, supporting its potential as a preventive hepatoprotective small molecule against xenobiotic-induced liver injury.\n\nID: 41552908\nTitle: Evaluation of Oral Acetaminophen on Tear Production and Intraocular Pressure in Healthy Dogs.\nAbstract: To assess the effects of a therapeutic dose of oral acetaminophen on Schirmer tear test I (STT-1) and intraocular pressure (IOP) in healthy dogs. Fourteen healthy adult beagle dogs. All animals underwent a physical and ophthalmic examination, hematology, and plasma biochemistry prior to treatment. Oral acetaminophen at 30\u2009mg/kg every 12\u2009h for 5\u2009days was administered. STT-1 and IOP were measured in both eyes before drug administration. Ocular adverse effects were assessed using a semiquantitative preclinical ocular toxicology scoring system. All measurements were performed by the same investigator under controlled environmental conditions. At the end time point, follow-up physical and ophthalmic examinations and blood workup were conducted. STT-1 remained stable throughout the study, with no significant differences between time points (p\u2009=\u20090.665) or overall trend over time (p\u2009=\u20090.356). IOP showed no consistent temporal trend (p\u2009=\u20090.602), although significant differences were observed between specific time points (p\u2009=\u20090.003). IOP at 24\u2009h was higher than at 12\u2009h (p\u2009=\u20090.031) and 60\u2009h (p\u2009=\u20090.009), and at 0\u2009h compared to 60\u2009h (p\u2009=\u20090.043); however, these differences were transient and clinically irrelevant (1-2\u2009mmHg). Mild conjunctival hyperaemia and fluorescein staining uptake were observed in 3/28 eyes, although these were mild and resolved spontaneously without treatment. No systemic adverse effects were detected. Oral therapeutic doses of acetaminophen for 5\u2009days did not affect STT-1 or IOP in healthy dogs. Further studies should evaluate its effects in dogs with systemic diseases, pre-existing ocular conditions, or as long-term or multi-drug regimen treatment.\n\nID: 40914889\nTitle: Canine Mdr1 Knockout MDCK Cells Reliably Estimate Human Small Intestinal Permeability (Peff) and Fraction Absorbed (fa).\nAbstract: Human intestinal permeability is a key determinant of the oral fraction absorbed (fa) of active pharmaceutical ingredients (APIs). This study evaluated the ability of an in-house canine Mdr1 (cMdr1) knockout (KO) Madin-Darby Canine Kidney (MDCK) cell line to correlate in vitro apparent permeability (Papp) with human small intestinal permeability (Peff). In vitro Papp values of 16 reference compounds with high, medium, or low permeabilities were measured in the in-house cMdr1 KO MDCK protocol under pH gradient (6.5 \u21d2 7.4) and pH equivalent conditions (7.4 \u21d2 7.4) and correlations with human Peff were established (R2 > 0.8). The correlations were subsequently used to estimate Peff and fa for six test APIs: acetaminophen, voriconazole, fedratinib, voxelotor, lemborexant, and istradefylline. The results for these APIs were compared against literature and permeability data from other methods routinely used in drug discovery and development. The projected Peff and fa values for the test APIs aligned well with literature permeabilities derived using other methods and clinical pharmacokinetic studies, respectively. This work highlights the usefulness of cMdr1 KO MDCK cells in permeability classification, especially for highly permeable APIs, and supports its broader use in both research and regulatory contexts.\n\nID: 39067762\nTitle: Effect of particle size on gastric emptying of enteric-coated granules in fasted beagle dogs: Relationship with interdigestive migrating motor complex.\nAbstract: This study investigates the particle size threshold at which the interdigestive migrating motor complex (IMMC) becomes active in gastric emptying for fasted beagle dogs. Enteric-coated granules containing cetirizine dihydrochloride (CET) were prepared in three particle sizes, 200, 660, and 1,200 \u00b5m (D50). To mark IMMC timing and water movement from the stomach, enteric-coated aspirin tablets and acetaminophen solution were used. To six fasted beagle dogs with 50 mL of acetaminophen solution was administered each granule size as a multiple-unit and a single enteric-coated aspirin tablet (3-period crossover study). No significant difference in pharmacokinetic parameters of CET after oral administration of different particle sizes was observed. However, the appearance time of CET in plasma with smaller granules (200 and 660 \u00b5m) was significantly faster than that of salicylic acid (a major metabolite of aspirin) in all dogs. In the case of the largest granules (1,200 \u00b5m), no significant time difference was observed in the appearance of both compounds in plasma. Furthermore, in two dogs, both compounds appeared at the same time, implying IMMC-regulated gastric emptying for the largest CET granules. These results support a particle size threshold between 660 and 1,200 \u00b5m for gastric emptying without IMMC action in fasted beagle dogs.\n\nID: 37125690\nTitle: Usefulness of the Beagle Model in the Evaluation of Paracetamol and Ibuprofen Exposure after Oral Administration to Pediatric Populations: An Exploratory Study.\nAbstract: The present study aimed to explore the usefulness of beagle dogs in combination with physiologically based pharmacokinetic (PBPK) modeling in the evaluation of drug exposure after oral administration to pediatric populations at an early stage of pharmaceutical product development. An exploratory, single-dose, crossover bioavailability study in six beagles was performed. A paracetamol suspension and an ibuprofen suspension were coadministered in the fasted-state conditions, under reference-meal fed-state conditions, and under infant-formula fed-state conditions. PBPK models developed with GastroPlus v9.7 were used to inform the extrapolation of beagle data to human infants and children. Beagle-based simulation outcomes were compared with published human-adult-based simulations. For paracetamol, fasted-state conditions and reference-meal fed-state conditions in beagles appeared to provide adequate information for the applied scaling approach. Fasted-state and/or reference-meal fed-state conditions in beagles appeared suitable to simulate the performance of ibuprofen suspension in pediatric populations. Contrary to human-adult-based translations, extrapolations based on beagle data collected under infant-formula fed-state conditions appeared less useful for informing simulations of plasma levels in pediatric populations. Beagle data collected under fasted and/or reference-meal fed-state conditions appeared to be useful in the investigation of pediatric product performance of the two investigated highly permeable and highly soluble drugs in the upper small intestine. The suitability of the beagle as a preclinical model to understand pediatric drug product performance under different dosing conditions deserves further evaluation with a broader spectrum of drugs and drug products and comparisons with pediatric in vivo data.\n\nID: 36931586\nTitle: Metabolism and disposition of JNJ-10450232 (NTM-006) in rats, dogs, monkeys and humans.\nAbstract: JNJ-10450232 (NTM-006), a novel non-opioid, non-nonsteroidal anti-inflammatory drug with structural similarities to acetaminophen, demonstrated anti-pyretic and/or analgesic activities in preclinical models and humans and reduced potential to cause hepatotoxicity in preclinical species. Metabolism and disposition of JNJ-10450232 (NTM-006) following oral administration to rats, dogs, monkeys and humans are reported. Urinary excretion was the major route of elimination based on recovery of 88.6% (rats) and 73.7% (dogs) of oral dose. The compound was extensively metabolized based on low recovery of unchanged drug in excreta from rats (11.3%) and dogs (18.4%). Clearance is driven by O-glucuronidation, amide hydrolysis, O-sulfation and methyl oxidation pathways. The combination of metabolic pathways driving clearance in human is covered in at least one preclinical species despite a few species-dependent pathways. O-Glucuronidation was the major primary metabolic pathway of JNJ-10450232 (NTM-006) in dogs, monkeys and humans, although amide hydrolysis was another major primary metabolic pathway in rats and dogs. A minor bioactivation pathway to quinone-imine is observed only in monkeys and humans. Unchanged drug was the major circulatory component in all species investigated. Except for metabolic pathways unique to the 5-methyl-1H-pyrazole-3-carboxamide moiety, metabolism and disposition of JNJ-10450232 (NTM-006) are similar to acetaminophen across species.\n\nID: 34281773\nTitle: Influence of general anaesthesia on the intravenous acetaminophen pharmacokinetics in Beagle dogs.\nAbstract: To determine if general anaesthesia influences the intravenous (IV) pharmacokinetics (PK) of acetaminophen in dogs. Prospective, crossover, randomized experimental study. A group of nine healthy Beagle dogs. Acetaminophen PK were determined in conscious and anaesthetized dogs on two separate occasions. Blood samples were collected before, and at 5, 10, 15, 30, 45, 60 and 90 minutes and 2, 3, 4, 6, 8, 12 and 24 hours after 20 mg kg-1 IV acetaminophen administration. Haematocrit, total proteins, albumin, alanine aminotransferase, aspartate aminotransferase, urea and creatinine were determined at baseline and 24 hours after acetaminophen. The anaesthetized group underwent general anaesthesia (90 minutes) for dental cleaning. After the administration of dexmedetomidine (3 \u03bcg kg-1) intramuscularly, anaesthesia was induced with propofol (2-3 mg kg-1) IV, followed by acetaminophen administration. Anaesthesia was maintained with isoflurane in 50% oxygen (Fe'Iso 1.3-1.5%). Dogs were mechanically ventilated. Plasma concentrations were analysed with high-performance liquid chromatography. PK analysis was undertaken using compartmental modelling. A Wilcoxon test was used to compare PK data between groups, and clinical laboratory values between groups, and before versus 24 hours after acetaminophen administration. Data are presented as median and range (p < 0.05). A two-compartmental model best described time-concentration profiles of acetaminophen. No significant differences were found for volume of distribution values 1.41 (0.94-3.65) and 1.72 (0.89-2.60) L kg-1, clearance values 1.52 (0.71-2.30) and 1.60 (0.91-1.78) L kg-1 hour-1 or terminal elimination half-life values 2.45 (1.45-8.71) and 3.57 (1.96-6.35) hours between conscious and anaesthetized dogs, respectively. Clinical laboratory variables were within normal range. No adverse effects were recorded. IV acetaminophen PK in healthy Beagle dogs were unaffected by general anaesthesia under the study conditions. Further studies are necessary to evaluate the PK in different clinical contexts.\n\nID: 33719822\nTitle: Acetaminophen and tramadol hydrochloride-loaded soft gelatin capsule: preparation, dissolution and pharmacokinetics in beagle dogs.\nAbstract: The objective of this study was to develop a novel acetaminophen and tramadol hydrochloride-loaded soft capsule (ATSC) with enhanced bioavailability of tramadol. The ATSC was manufactured in a pilot-scale batch size with the capsule contents composed of tramadol, acetaminophen, PEG 400 and Capmul MCM at a weight ratio of 37.5:325:177.5:30. Moreover, its dissolution, stability and pharmacokinetics in beagle dogs were carried out compared to commercial tablet. The dissolved amounts of acetaminophen from the ATSC and commercial tablet were not significantly different. However, compared to the latter, the former had significantly higher dissolution rate of tramadol at the initial times. In beagle dogs, the ATSC provided no significant difference in plasma concentrations and AUC of acetaminophen than did the commercial tablet; however, it significantly improved those of tramadol compared to the other, indicating the enhanced oral bioavailability of tramadol. Compared to the commercial tablet, the ATSC had a larger AUC value for tramadol (55.27\u2009\u00b1\u200911.06 vs. 92.62\u2009\u00b1\u200921.52\u2009h\u00b7ng/ml). In the accelerated long-term stability, the ATSC offered higher than 96% drug content of acetaminophen and tramadol, suggesting that it was stable for at least six months. Therefore, this ATSC would be a recommendable candidate with enhanced oral bioavailability and excellent stability.\n\nID: 33212160\nTitle: In\u00a0Vitro and In\u00a0Vivo Evaluation of 3D Printed Capsules with Pressure Triggered Release Mechanism for Oral Peptide Delivery.\nAbstract: In this study a 3D printed capsule designed to break from the physiological pressures in the antropyloric region was evaluated for its ability to deliver the synthetic octapeptide octreotide in beagle dogs when co-formulated with the permeation enhancer sodium caprate. The pressure sensitive capsules were compared to traditional enteric coated hard gelatin capsules and enteric coated tablets. Paracetamol, which is completely absorbed in dogs, was included in the formulations and used as an absorption marker to give information about the in\u00a0vivo performance of the dosage forms. The pressure sensitive capsules released drug in 50% of the dogs. In the cases where drug was released, there was no difference in octreotide bioavailability or Cmax compared to the enteric coated dosage forms. When comparing all dosage forms, a correlation was seen between paracetamol Cmax and octreotide bioavailability, suggesting that a high drug release rate may be beneficial for peptide absorption when delivered together with sodium caprate.\n\nID: 32715494\nTitle: Pharmacokinetics of acetaminophen after intravenous and oral administration in fasted and fed Labrador Retriever dogs.\nAbstract: Acetaminophen (paracetamol) is used in dogs to manage fever and mild pain. The aim of this study was to assess the pharmacokinetics of acetaminophen in both fed and fasted Labrador Retrievers after a single intravenous and oral administration (20\u00a0mg/kg). Six healthy dogs underwent three treatments in a randomized block study (a, n\u00a0=\u00a02; b, n\u00a0=\u00a02; c, n\u00a0=\u00a02). In phase one, group a received acetaminophen intravenously, group b and c orally after being fasted and fed, respectively. In phase two and three, groups were swapped, and the experiment was repeated. At the end of the trial, each dog received the same treatment. Acetaminophen plasma concentrations were detected using a validated HPLC-UV method. The pharmacokinetic analysis was performed using a noncompartmental model. Clearance, volume at steady state and half-life of acetaminophen in Labrador Retrievers were 0.42\u00a0L/kg\u00a0hr, 0.87\u00a0L/kg and 1.35\u00a0hr, respectively. No significant statistical differences were found between fasted and fed dogs regarding maximum plasma concentration, time at maximum concentration and bioavailability as measured by the AUC. Feeding does not significantly affect the acetaminophen oral pharmacokinetics.\n\nID: 32486088\nTitle: The Use of Capsule Endoscopy to Determine Tablet Disintegration In Vivo.\nAbstract: The preferred delivery route for drugs targeted for systemic effect is by oral administration. Following oral administration, a solid dosage form must disintegrate and the drug dissolve, thereafter permeating the intestinal mucosa. Several different in vitro methods are used to investigate these processes, i.e., disintegration tests, dissolution tests, and permeability models. However, the actual behavior of oral dosage forms in the environment of the gastro-intestinal tract is not very well elucidated using these conventional methods. In this study, the use of capsule endoscopy to determine tablet disintegration in vivo was assessed. Panadol and Panadol Rapid (acetaminophen/paracetamol) were used as the test material. The in vivo tablet disintegration behavior in beagle dogs was assessed by the use of capsule endoscopy. The in vitro tablet disintegration behavior was assessed using the European Pharmacopeia (Ph. Eur.) disintegration test. The study showed that the in vivo disintegration times of Panadol and Panadol Rapid were 24.7 and 16.5 min, respectively, when determined by capsule endoscopy, which corresponded to the pharmacokinetic data. By contrast, the in vitro disintegration times of the same formulations were 5.5 and 4.0 min, respectively, when determined by the Ph. Eur. disintegration test. In conclusion, capsule endoscopy can be used to determine the in vivo tablet disintegration behavior. By contrast, the in vitro methods appear to not be predictive of the disintegration behavior in vivo but may be used to rank the order the formulations with respect to disintegration time.\n\nID: 30713054\nTitle: Comparative pharmacokinetics and a clinical laboratory evaluation of intravenous acetaminophen in Beagle and Galgo Espa\u00f1ol dogs.\nAbstract: To assess the pharmacokinetics (PK) and conduct a clinical laboratory evaluation of acetaminophen in Beagle and Galgo Espa\u00f1ol (GE) dogs. Prospective randomized experimental trial. A total of 20 healthy dogs - 10 Beagles and 10 GE (six males and four females in both groups). Acetaminophen (10 and 20 mg kg-1) was administered intravenously (IV) to the dogs on two different occasions. Plasma concentrations were analysed by high-performance liquid chromatography. PK analysis was undertaken using compartmental modelling with ADAPT 5 software. Simulations after multiple IV doses were investigated. Clinical laboratory values such as red blood cell (RBC) count, haemoglobin (Hb), haematocrit (Ht), white blood cell (WBC) count, platelet count, total proteins, alanine aminotransferase (ALT), aspartate aminotransferase, urea and creatinine were measured before and 24 hours after acetaminophen administration in combination with clinical examination to assess side effects resulting from the drug. A two-compartmental model best described time-concentration profiles of acetaminophen. PK parameters were different as a result of a breed effect. For doses of 10 and 20 mg kg-1, respectively, clearance values were 1.70 (1.15-2.27) and 1.62 (1.06-2.86) L kg-1 hour-1 for Beagles and 1.18 (0.70-1.39) and 1.08 (0.67-1.35) L kg-1 hour-1 for GE; elimination half-life values were 2.64 (0.52-4.46) and 2.86 (0.87-4.63) hours for Beagles and 3.49 (1.89-7.80) and 4.57 (2.08-8.90) hours for GE. Significant differences were also found between GE and Beagles in the RBC count, Ht, Hb, WBC count and serum ALT before drug administration, and these differences were maintained 24 hours later, independent of the dosage used. For each breed, no side effects resulting from IV acetaminophen administration were observed at doses of either 10 or 20 mg kg-1. IV PK of acetaminophen was different between Beagles and GE dogs. Side effects were not detected. Further studies are necessary to evaluate the PK in a clinical context.\n\nID: 29756216\nTitle: Bioavailability of suppository acetaminophen in healthy and hospitalized ill dogs.\nAbstract: To determine the plasma pharmacokinetics of suppository acetaminophen (APAP) in healthy dogs and clinically ill dogs. This prospective study used six healthy client-owned and 20 clinically ill hospitalized dogs. The healthy dogs were randomized by coin flip to receive APAP orally or as a suppository in crossover study design. Blood samples were collected up to 10\u00a0hr after APAP dosing. The hospitalized dogs were administered APAP as a suppository, and blood collected at 2 and 6\u00a0hr after dosing. Plasma samples were analyzed by ultra-performance liquid chromatography with triple quadrupole mass spectrometry. In healthy dogs, oral APAP maximal concentration (CMAX =2.69\u00a0\u03bcg/ml) was reached quickly (TMAX =1.04\u00a0hr) and eliminated rapidly (T1/2\u00a0=\u00a01.81\u00a0hr). Suppository APAP was rapidly, but variably absorbed (CMAX =0.52\u00a0\u03bcg/ml TMAX =0.67\u00a0hr) and eliminated (T1/2 \u00a0=\u00a03.21\u00a0hr). The relative (to oral) fraction of the suppository dose absorbed was 30% (range <1%-67%). In hospitalized ill dogs, the suppository APAP mean plasma concentration at 2\u00a0hr and 6\u00a0hr was 1.317\u00a0\u03bcg/ml and 0.283\u00a0\u03bcg/ml. Nonlinear mixed-effects modeling did not identify significant covariates affecting variability and was similar to noncompartmental results. Results supported that oral and suppository acetaminophen in healthy and clinical dogs did not reach or sustain concentrations associated with efficacy. Further studies performed on different doses are needed.\n\nID: 42276124\nTitle: Clonidine-induced delayed gastric emptying persists despite prokinetic therapy in dogs fed a liquid meal as assessed by acetaminophen absorption.\nAbstract: To evaluate the effects of metoclopramide and azithromycin on liquid-phase gastric emptying (GE) in a clonidine-induced delayed GE model using the acetaminophen absorption test (AAT). This was a randomized crossover study of healthy, purpose-bred, mixed-breed dogs performed in a controlled laboratory setting from May through July 2023. Dogs received 1 of 4 treatments 1 hour before ingesting a liquid meal containing 25% of their resting energy requirement and 20 mg/kg acetaminophen: no treatment (control), clonidine (0.03 mg/kg, SC), clonidine plus azithromycin (4 mg/kg, IV), or clonidine plus metoclopramide (0.5 mg/kg, SC). Using high-power liquid chromatography, plasma acetaminophen concentrations were measured in 11 samples collected preprandially and at 10 time points between 0.5 and 24 hours postprandially. Time to peak concentration was used as a proxy for GE time. Results were analyzed by 2-way ANOVA with Sidak post hoc comparisons. 8 intact female dogs were included and received all 4 treatments in a random sequence. All dogs tolerated the AAT procedure well. Clonidine significantly delayed GE, increasing time to peak concentration from 80.6 \u00b1 15.9 minutes to 187.5 \u00b1 53.8 minutes. Neither metoclopramide nor azithromycin reversed this delay. The AAT identified delayed liquid-phase GE following clonidine administration. However, at the investigated dosages, metoclopramide and azithromycin did not mitigate clonidine-induced delayed GE. The AAT shows potential as a clinical tool for identifying delayed GE of liquids, particularly in critically ill or postoperative patients.\n\nID: 42176063\nTitle: Diagnosis of acetaminophen and codeine poisoning in a dog using earwax analysis by headspace gas chromatography-mass spectrometry (HS/GC-MS).\nAbstract: Poisoning of companion animals resulting from exposure to analgesics intended for human use is a frequent and clinically relevant problem in veterinary practice, usually associated with administration without professional supervision. This can induce severe systemic toxicity. Diagnostic confirmation can be particularly challenging in cases presenting with nonspecific clinical signs or when conventional biological samples are unavailable. This case report describes the innovative use of earwax as a non-invasive biological matrix for toxicological confirmation in veterinary medicine. A 9-year-old male mixed-breed dog was admitted following a traumatic accident and subsequent administration by its owner of a human medication containing acetaminophen and codeine. Clinical evaluation revealed lethargy, hypersalivation, hyporexia, dehydration, and neurological abnormalities. Laboratory findings demonstrated neutrophilic leukocytosis and marked increases in hepatic enzyme activities, consistent with acute hepatocellular injury. Toxicological investigation using headspace gas chromatography-mass spectrometry detected acetaminophen-related signatures in an earwax sample, supporting suspected exposure to the drug. Intensive treatment was promptly initiated and included fluid therapy, antidotal treatment with N-acetylcysteine, opioid antagonism, analgesia, and supportive care. The patient showed progressive clinical improvement, with complete resolution of clinical signs and full recovery. This case highlights the significant risks of administering human medications to companion animals and underscores the need to improve owner awareness of self-medication practices. Furthermore, it demonstrates the diagnostic potential of earwax as a non-invasive biological matrix for toxicological confirmation, expanding the range of complementary diagnostic tools available for veterinary toxicology and supporting improved clinical decision-making in cases of suspected pharmaceutical intoxication.\n\nID: 41947679\nTitle: Comparison of cytochrome P450 activity and mRNA expression in canine vs. human hepatocytes after acetaminophen, diclofenac, or valproic acid exposure.\nAbstract: Although extensive studies have been conducted on cytochrome P450 (CYP) enzymes in rodents and humans, research on canine CYP enzymes is limited. The lack of species-specific metabolic research on dogs presents a major challenge in predicting toxicity and adverse drug reactions. This study aimed to examine the interspecies differences in CYP enzyme activity and mRNA expression between canine and human hepatocytes following treatment with acetaminophen (AAP), diclofenac (Dic), or valproic acid (VPA). We determined the 24-h exposure half-maximal inhibitory concentration (IC\u2085\u2080) values of AAP, Dic, and VPA in canine and human hepatocytes. Based on these IC\u2085\u2080 concentrations, we compared drug-induced alterations in various parameters, including immunocytochemistry, transcriptomic profiles (RNA-seq), and CYP activity, to assess changes at the gene and protein levels. AAP and VPA increased CYP2J2 mRNA expression by 4.7- and 7.76-fold, respectively, whereas Dic increased CYP1A1 mRNA expression by 14.25-fold in canine hepatocytes. AAP, VPA, and Dic decreased CYP26B1 mRNA expression in canine hepatocytes by 0.03-, 0.12-, and 0.17-fold, respectively. Dic and VPA increased CYP1A1 mRNA expression by 5.53- and 6.66-fold, respectively, whereas AAP, VPA, and Dic decreased CYP4F22 mRNA expression by 0.03-, 0.13-, and 0.13-fold, respectively, in human hepatocytes. The observed differences between species in CYP activity and mRNA levels in response to drug exposure highlight the importance of accurate and precise experimental models for the development of new medications.\n\nID: 41142969\nTitle: Pharmaceutical exposure and toxicosis in dogs: A retrospective study of 223 cases from a Canadian veterinary teaching hospital (2018 to 2023).\nAbstract: Ingestion of pharmaceuticals is a common cause of poisoning and hospitalization in companion animals. Pets may be exposed through accidental over-administration of a prescribed veterinary drug, intentional administration of a human drug that owners do not realize is unsuitable for animals, or access to unattended medications. Our objective was to document cases of exposure and toxicosis due to suspected and confirmed pharmaceutical ingestion in dogs admitted to a veterinary teaching hospital over a 6-year period (2018 to 2023). Medical records were retrieved from the veterinary hospital database using keywords related to general poisoning. Results were then filtered using keywords related specifically to pharmaceutical ingestion while excluding non-pharmaceutical poisoning cases. Information pertaining to hospitalization, patient signalment, treatment, and case progression was collected and analyzed to characterize common factors in canine pharmaceutical poisoning cases. Pharmaceutical ingestion was reported in 223 canine poisoning cases (confirmed in 102 cases) over 6 y. There were 32 categories of pharmaceutical ingested over the study period. The most common were nonsteroidal anti-inflammatory drugs (n = 86) and acetaminophen (n = 29). The most common patient signalment was spayed female, young (\u22644 y), and large breed (particularly, Labrador retrievers). Normal clinical examinations on presentation were noted in 164 cases. Accidental drug exposures were more common than intentional pharmaceutical administrations (n = 211 and n = 12, respectively). The occurrence of cases related to exposure to human pharmaceuticals was 5\u00d7 that of cases related to veterinary pharmaceuticals. Only 1 dog of 223 was euthanized, for a survival-to-discharge rate of 99.6%. The most common therapies administered were emesis induction, activated charcoal, fluid support, and gastroprotectant. Pharmaceutical exposure, especially from over-the-counter human medications, was a common reason for hospital admission among the dogs described in this study. Improved client education is needed to avoid preventable pharmaceutical exposures. Exposition aux m\u00e9dicaments et toxicose chez les chiens : \u00e9tude r\u00e9trospective de 223 cas dans un h\u00f4pital v\u00e9t\u00e9rinaire universitaire canadien (2018 \u00e0 2023). L\u2019ingestion de produits pharmaceutiques est une cause fr\u00e9quente d\u2019intoxication et d\u2019hospitalisation chez les animaux de compagnie. Les animaux de compagnie peuvent \u00eatre expos\u00e9s par suradministration accidentelle d\u2019un m\u00e9dicament v\u00e9t\u00e9rinaire prescrit, par administration intentionnelle d\u2019un m\u00e9dicament humain dont les propri\u00e9taires ignorent qu\u2019il est inappropri\u00e9 pour les animaux, ou par acc\u00e8s \u00e0 des m\u00e9dicaments laiss\u00e9s sans surveillance. Notre objectif \u00e9tait de documenter les cas d\u2019exposition et de toxicose dus \u00e0 l\u2019ingestion suspect\u00e9e et confirm\u00e9e de m\u00e9dicaments chez des chiens admis dans un h\u00f4pital v\u00e9t\u00e9rinaire universitaire sur une p\u00e9riode de 6 ans (2018 \u00e0 2023). Les dossiers m\u00e9dicaux ont \u00e9t\u00e9 extraits de la base de donn\u00e9es de l\u2019h\u00f4pital v\u00e9t\u00e9rinaire \u00e0 l\u2019aide de mots-cl\u00e9s li\u00e9s \u00e0 l\u2019intoxication g\u00e9n\u00e9rale. Les r\u00e9sultats ont ensuite \u00e9t\u00e9 filtr\u00e9s \u00e0 l\u2019aide de mots-cl\u00e9s li\u00e9s sp\u00e9cifiquement \u00e0 l\u2019ingestion de m\u00e9dicaments, tout en excluant les cas d\u2019intoxication non pharmaceutique. Les informations relatives \u00e0 l\u2019hospitalisation, aux signalements des patients, au traitement et \u00e0 l\u2019\u00e9volution des cas ont \u00e9t\u00e9 recueillies et analys\u00e9es afin de caract\u00e9riser les facteurs communs aux cas d\u2019intoxication pharmaceutique canine. L\u2019ingestion de m\u00e9dicaments a \u00e9t\u00e9 signal\u00e9e dans 223 cas d\u2019intoxication canine (confirm\u00e9e dans 102 cas) sur une p\u00e9riode de 6 ans. Trente-deux cat\u00e9gories de m\u00e9dicaments ont \u00e9t\u00e9 ing\u00e9r\u00e9es au cours de la p\u00e9riode d\u2019\u00e9tude. Les plus fr\u00e9quents \u00e9taient les anti-inflammatoires non st\u00e9ro\u00efdiens (n = 86) et l\u2019ac\u00e9taminoph\u00e8ne (n = 29). Les signalements les plus fr\u00e9quents concernaient les femelles st\u00e9rilis\u00e9es, les jeunes (\u22644 ans) et les chiens de grande race (en particulier les Labradors retrievers).

This study evaluated the PK, postoperative analgesic effects, pharmacodynamics (PD), and safety of intravenous acetaminophen in dogs undergoing laparoscopic ovariohysterectomy. In a randomized, blinded trial, two doses of acetaminophen (10 and 20\u00a0mg/kg IV every 8\u00a0h for 24\u00a0h) were compared to buprenorphine (20\u00a0\u03bcg/kg IV every 8\u00a0h). The first dose was administered at extubation. Pain was assessed using the Glasgow Composite Measure Pain Scale-Short Form (CMPS-SF) and mechanical nociceptive thresholds during 24\u00a0h. A nonlinear mixed-effects model was used to characterize drug disposition, identify plasma analgesic concentration thresholds, and describe pain score evolution over time. Haematological, hepatic, and renal parameters were measured before and 24\u00a0h after treatment. Fifty-nine dogs were included. Both acetaminophen doses provided analgesia comparable to buprenorphine. CMPS-SF scores mostly remained between 0 and 2. PK was best described by a two-compartment model, with peak concentrations of 11.49 (7.89\u00a0%) and 19.78 (5.18\u00a0%) \u03bcg/mL and the lower concentrations of 0.11 (71.73\u00a0%) and 0.24 (62.06\u00a0%) \u03bcg/mL for 10 and 20\u00a0mg/kg, respectively. The PD model demonstrated sustained analgesia over time. Greyhounds exhibited higher pain scores at several time points, suggesting breed-specific differences in pain sensitivity and drug disposition. No adverse effects were observed. These findings support the use of acetaminophen as a safe and effective analgesic for postoperative pain management in dogs, with the potential need for individualized protocols based on breed-specific responses.\n\nID: 40971596\nTitle: Craniomandibular Osteopathy in a Newfoundland Dog.\nAbstract: A 5-month-old Newfoundland dog was presented with lethargy and bilateral enlargement of the mandibles and maxillae. A diagnosis of craniomandibular osteopathy was made based on clinical signs, physical examination, and computed tomography findings. Improved mentation and comfort levels were achieved with pain management using meloxicam and paracetamol. Follow-up examinations were performed at 1, 2, 6, and 16 weeks after the first consultation. Stabilization of the condition was noted initially, and by 16 weeks, clinical symptoms had markedly improved. Protuberances of the maxillae were markedly reduced compared to the initial presentation, and the maxillae appeared nearly normal. Widening of the mandibles had decreased, and the bony swelling extended less caudally. To the authors' knowledge, this is the first report of craniomandibular osteopathy in a Newfoundland dog.\n\nID: 40510286\nTitle: Suspected clinical methemoglobinemia associated with administration of hydrogen peroxide 3% in a dog treated for acute ibuprofen ingestion.\nAbstract: An 8-month-old intact male golden retriever dog was presented to the emergency department of a large private-practice specialty hospital. The dog had become cyanotic and collapsed following administration (orogastric tube) of 1.4 mL/kg of hydrogen peroxide 3% to induce emesis for ibuprofen ingestion. The dog had severe methemoglobinemia (33%; reference range: 0.3 to 1.5%) and developed anemia. The methemoglobinemia resolved after 24 h of hospitalization with supportive care. Results from assessment with high-performance liquid chromatography/tandem mass spectrometry were consistent with ibuprofen ingestion, with no acetaminophen detected. Key clinical message: This case demonstrated methemoglobinemia in a dog following both ibuprofen ingestion and hydrogen peroxide 3% administration.

There have been no previous reports of significant neuropathic pain or sciatic neuritis following total hip arthroplasty (THA) in dogs. This case report describes a male neutered Samoyed dog, aged 21 months and weighing 26 kg, with severe pain after THA that underwent revision surgery 2 days after the initial surgery. During the 36 hours after the initial surgery, analgesia was well managed with preventive and multimodal analgesic approaches (methadone, meloxicam, medetomidine infusion, epidural injection of bupivacaine and morphine). After this, the level of pain increased substantially and was refractory to treatment (revision surgery, methadone, ketamine and medetomidine infusions, paracetamol and gabapentin). Neuropathic pain was suspected based on signs of allodynia (hypersensitivity to gentle palpation of the affected limb) and concern for paraesthesia (sporadic vocalization and attempts of self-mutilation). The dog had no neurological deficits, and there were no significant findings on revision surgery or serial radiography. Ultrasonography of the sciatic nerve revealed marked hyperechoic thickening of the epineurium, suggestive of neuritis. A single perineural injection with a mixture of methylprednisolone (0.6 mL, 4%, 1 mg kg-1) and bupivacaine (3 mL, 0.5%, 0.6 mg kg-1) was injected proximal to the affected sciatic nerve via a modified parasacral approach under ultrasound guidance. The level of pain rapidly subsided following perineural injection, allowing for reduction of systemic analgesic use and return of the dog to its owner. The remainder of the recovery period was uneventful with no recurrence of significant pain at the time of most recent follow-up, 153 days after initial surgery.\n\nID: 39606656\nTitle: Case series: Cervical far-lateral and combined cervical far lateral/foraminal intervertebral disk extrusions in 10 dogs.\nAbstract: Far-lateral intervertebral disk extrusions (IVDEs) have been reported infrequently in dogs in veterinary literature, mostly affecting the caudal lumbar intervertebral disks. We describe the clinical findings, computed tomography (CT) and magnetic resonance imaging (MRI) findings, treatment, and outcome in 10 dogs with cervical far-lateral IVDEs. Patient databases of 3 small animal hospitals and 1 veterinary teleradiology service were retrospectively searched for patients in which imaging studies (CT or MRI) identified the presence of intervertebral disk material outside the limits of the intervertebral foramen. Presenting clinical signs included: episodic signs of cervical pain (6/10, 30%), persistent signs of cervical pain (3/10, 50%), nerve root signature or lameness (5/10, 50%), and abnormal cervical posture only (excluding nerve root signature) (1/10, 10%). Affected IVD spaces (for 11 IVDEs in 10 dogs) included: C3-4 (6/11, 55%), C5-6 (3/11, 27%), and C2-3 (2/11, 18%). Nerve root signature was not reported for C2-3 IVDEs. All cases were managed medically (without surgery). The top 3 used medications were gabapentinoids (10/10, 100%), non-steroidal anti-inflammatory drugs (NSAIDs) (10/10, 100%), and paracetamol (3/10, 30%). Median treatment duration was 25\u2009days (range 10-84). Short-term outcome (<3\u2009months) was recorded in 9/10 (90%) cases. Resolution of clinical signs was reported in 7/9 (78%) cases. Long-term follow-up was available for 6/10 (60%) cases (median 11.5\u2009months, range 5.5-30\u2009months); 5/6 (83%) showed resolution of clinical signs. Recurrence of clinical signs was reported in 1 case (9\u2009months later), managed medically again, with successful outcome. In conclusion, cervical far-lateral disk extrusions are a rare clinical entity in dogs, but can result in severe, persistent or episodic, pain. Medical management is associated with a positive short- and long-term outcome in most cases.\n\nID: 39122304\nTitle: A 36-Year-Old Woman With Intermittent Cyanosis.\nAbstract: A 36-year-old woman with a medical history of opioid use disorder and frequent urinary tract infections presented to the ED from her opioid use disorder clinic, where she was found to have an oxygen saturation by pulse oximetry (Spo2) of 82%\u00a0on room air. Starting 3\u00a0days before presentation, the patient's family noted worsening pale complexion and blue lips at rest. These findings of cyanosis had occurred a few times before and always resolved within a couple days without any medical intervention. She had no pulmonary symptoms outside of long-standing dyspnea with moderate exertion when at work or doing chores around the house. Her medications included methadone 160\u00a0mg daily, acetaminophen 650\u00a0mg nightly as needed, and phenazopyridine 199\u00a0mg three times daily as needed for increased urinary frequency and urethral discomfort that lasted a maximum of 4\u00a0days at a time. She confirmed she had started taking a new course of phenazopyridine 4\u00a0days before presenting to the ED. She had no dietary restrictions, had been eating her normal diet, and lived in a mobile home with her family, two dogs, and a gerbil. The patient reported using less than 10 tobacco cigarettes per day, one marijuana cigarette nightly, and no alcohol or other drugs. She worked in a warehouse stacking prepackaged bread.\n\nID: 38717831\nTitle: Use of orally administered dexmedetomidine to induce emesis in cats.\nAbstract: This case series describes the use of orally administered dexmedetomidine at a dose of 20 \u00b5g/kg to induce emesis in six cats. Emesis was successfully induced in 5/6 cats, with each of the cats vomiting once. The reasons for inducing vomiting included known or suspected ingestion of lilies, onions, acetaminophen (paracetamol) or acetylsalicylic acid. Four of the five cats in which emesis induction was successful did not develop any clinical signs of toxicity associated with the toxin ingested; the fifth cat developed clinicopathological changes consistent with acetaminophen toxicity. All six cats exhibited moderate to profound sedation, as expected, but no other adverse effects were documented. Induction of emesis in cats is notoriously difficult. This case series describes a novel route of administration of dexmedetomidine, a commonly available medication, with a high success rate observed for inducing emesis in this group of cats. Cats are notoriously more difficult to elicit vomiting in than dogs. This case series describes the use of a novel way of giving cats a commonly available veterinary medication to cause vomiting. The medication, dexmedetomidine, was given by mouth to six cats, of which five vomited. All six cats had eaten toxins: lilies, acetaminophen (paracetamol), aspirin or onions. Four of the five cats that vomited did not develop any signs of toxicity. All six cats that received the medication became sedated, but no other side effects were noted.\n\nID: 42006561\nTitle: The peri / postoperative analgesic effect of intravenous paracetamol in dogs.\nAbstract: In healthy dogs undergoing a surgical procedure, is there improved pain control in dogs receiving intravenous paracetamol in the peri / postoperative period compared to dogs not receiving intravenous paracetamol? Treatment. Three randomised, controlled, and blinded studies. Two studies directly address the PICO question whereby postoperative pain assessment was clinically evaluated following intravenous (IV) paracetamol. The third study addressed the question to a lesser extent, whereby the impact on the sevoflurane minimum alveolar concentration (MAC) reduction in response to noxious stimuli was assessed following the administration of IV paracetamol. Weak. The findings of the first two studies presented appear to directly contradict each other. The first study demonstrated a reduction in pain in all groups and found no differences in analgesia between IV paracetamol and other non-steroidal anti-inflammatories drugs (NSAIDs), while the second study reported no analgesia effects from IV paracetamol and was terminated prematurely because a high number of dogs required rescue analgesia. The first study reported sufficient analgesic effects of IV paracetamol and the second study reported no analgesia effects of IV paracetamol. Both were blinded, randomised, controlled studies and directly addressed the PICO question in relation to the peri / postoperative analgesic effects of IV paracetamol. However, their methods and sample sizes were very different. The third study did not demonstrate a clinically relevant sevoflurane MAC reduction after IV paracetamol in dogs. At present, there is limited and weak evidence to suggest that IV paracetamol provides peri / postoperative analgesia in dogs. However, further studies are required to better assess its efficacy, its duration of action, and the appropriate doses that are necessary to reach therapeutic plasma levels. The reduced incidence of side effects at the currently recommended doses could support its peri / postoperative use, where NSAIDs use is contraindicated.\n\nID: 37882359\nTitle: Persistent socket pain in a dog after the enucleation of the eye and its clinical management.\nAbstract: Persistent socket pain is a condition described in humans after enucleation of the eye. This report aims at describing this condition in dogs. A 10-year-old male-neutered crossbreed was presented to the referral veterinary surgeon for enucleation of the right ocular globe. Anaesthesia and surgery were uneventful although during the postoperative period the dog was reluctant to open the mouth and to be explored by the referral veteterinary surgeon. Despite treatment with meloxicam, paracetamol and tramadol, no improvements were observed. Ten weeks after surgery, the dog was referred to the Dick White referrals for further investigations. Ophthalmic examination was normal, though palpation of the wound triggered an avoidance response. Magnetic resonance imaging showed changes compatible with orbital cellulitis. The area of interest was evaluated with the use of the mechanical Von Frey filaments. A response, characterised by sudden turning of the head and attempts to withdraw it, was evoked with filament 4.93 (8.0\u00a0g) during stimulation of the periorbital area. After induction of anaesthesia, an ultrasound-guided injection containing levobupivacaine 0.5% and methylprednisolone was performed within the retrobulbar area. Three hours after recovery from anaesthesia, no discomfort was observed during palpation of the area. Re-evaluation was performed with the Von Frey filaments; no response could be evoked during testing with all 20 filaments (from 2.36 to 6.65) applied on either side of the face. The patient was discharged with a course of gabapentin and, 3 weeks after the intervention, the dog showed no clinical signs of pain. Persistent socket pain is an unpleasant sensation at the level of the enucleated orbit, and it should be regarded as a challenging condition to diagnose and treat. The MRI findings appeared to be essential to select the most appropriate interventional treatment. The injection of local anaesthetic and steroid into the retrobulbar space was useful for both confirming the diagnosis and treating pain by reducing the peripheral signalling and decreasing the residual inflammation.\n\nID: 38256887\nTitle: The Use of Population Pharmacokinetics to Extrapolate Food Effects from Human Adults and Beagle Dogs to the Pediatric Population Illustrated with Paracetamol as a Test Case.\nAbstract: To date, food-drug interactions in the pediatric population remain understudied. The current food effect studies are mostly performed in adults and do not mimic the real-life situation in the pediatric population. Since the potential benefits of food effect studies performed in pediatrics should be counterbalanced with the burden that these studies pose to the patients, alternative research strategies should be evaluated. The present study aimed to evaluate whether population pharmacokinetics (popPK) using data in beagle dogs and human adults could reliably assess food effects relevant for the pediatric population. PopPK was utilized to understand the performance of paracetamol under different dosing conditions (when the participants were fasted, with a reference meal, and with infant formula) in human adults (n = 8) and beagle dogs (n = 6) by constructing models to derive the pharmacokinetic parameters and to evaluate the food effects in both species. A two-compartment model with a single input function for the absorption phase best described the profiles of paracetamol in the beagle dogs. In the human adults, a one-compartment model with a dual input function for the absorption phase best described the data. The simulated profiles for the different dosing conditions demonstrated that both the human adults' and beagle dogs' simulations were able to acceptably describe the plasma concentration-time profiles of paracetamol observed in a representative pediatric population, which opens up perspectives on pediatric-relevant food effect predictions. However, the obtained results should be carefully interpreted, since an accurate validation of these findings was not possible due to the scarcity of the literature on observed pediatric data.\n\nID: 37576835\nTitle: Case report: Neuropathic pain versus undesirable behavior in a Dachshund after hemilaminectomy surgery for an intervertebral disc extrusion.\nAbstract: A 5.5\u2009years-old male Dachshund was presented for evaluation because of undesirable behavior including barking, biting, sucking and licking the right-side flank, ventrally and slightly caudally to the level of the surgical incision 7\u2009days after hemilaminectomy for a right-sided L1-2 intervertebral disc extrusion. The dog was being treated with oral gabapentin 10\u2009mg/kg q8h. Repeat clinical examination on three occasions after post-operative discharge did not reveal any signs of hyperesthesia or neurological deficits and the behavior was not observed in the clinic during consultations. During a separate day of hospital admittance with the aim of evaluating for the presence or absence of the behavior, the dog also did not exhibit the behavior. Oral paracetamol 12\u2009mg/kg q8h was added to medical treatment. When the dog was discharged and returned home, the behavior was immediately seen again. When the owners implemented verbal punishment, the behavior immediately ceased. The owner verbally corrected the dogs' behavior for two excitative days. Upon telephone consultation 3\u2009days later, the owner reported that they only had observed three recurrences of the behavior that immediately ceased following verbal correction and did not recur thereafter. Oral analgesic medication was tapered and discontinued. No recurrence of the behavior was noticed during the next 2\u2009months. The authors postulated the dog possibly expressed signs of neuropathic pain in the post-operative period, or that the behavior was of a \"compulsive disorder-like\" nature as it only occurred when the dog was at home and in the presence of the owner. The eventual outcome and result of verbal corrections implemented by the owner seem to support the latter. In conclusion, compulsive-like undesirable behavior should be considered a differential diagnosis in dogs in the post-operative period of procedures possibly associated with the development or expression of signs of neuropathic pain.\n\nID: 36608923\nTitle: Preclinical safety assessment of JNJ-10450232 (NTM-006), a structural analog of acetaminophen, that does not cause hepatotoxicity at supratherapeutic doses.\nAbstract: JNJ-10450232 (NTM-006) is a new molecular entity that is structurally related to acetaminophen. A comprehensive non-clinical safety program was conducted to support first-in-human and clinical efficacy studies based on preclinical data suggesting that the compound has comparable or enhanced antinociceptive and antipyretic efficacy without causing hepatotoxicity at supratherapeutic doses. No hepatic toxicity was noted in a mouse model sensitive to acetaminophen hepatotoxicity or in rats, dogs, and non-human primates in 28-day repeat dose toxicity studies at and above doses/exposures at which acetaminophen is known to cause hepatotoxicity. In the 28-day toxicity studies, all treatment-related findings were monitorable and reversible. Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen. This finding is considered not relevant to humans due to species differences in metabolism. Thyroid hypertrophy and hyperplasia were also observed in dogs and were shown to be a consequence of a species-specific UGT induction also demonstrated with increased thyroid hormone metabolism. Indirect bilirubin elevation was observed in rats as a result of UGT1A1 Inhibition. JNJ-10450232 (NTM-006) had no toxicologically relevant findings in safety pharmacology or genotoxicity studies. Together, these data supported progressing into safety and efficacy studies in humans.\n\nID: 35512023\nTitle: Prophylactic efficacy of intravenous paracetamol administration to reduce the incidence of post-operative ocular hypertension in dogs undergoing phacoemulsification: A pilot study.\nAbstract: To determine whether intravenous administration of paracetamol can prevent postoperative ocular hypertension (POH) in dogs following routine phacoemulsification. Diabetic and non-diabetic patients (total 54 dogs) undergoing unilateral or bilateral phacoemulsification were recruited to this placebo-controlled, prospective study. The control group received 1\u2009ml/kg saline via intravenous infusion while the treatment group received 10\u00a0mg/kg paracetamol via intravenous infusion. Infusions were administered 30\u00a0min prior to surgery and repeated 12\u00a0h following initial administration. All patients received topical latanoprost at the conclusion of surgery. Intraocular pressure (IOP) was measured before premedication (baseline), and at 1\u00a0h, 3\u00a0h, 5\u00a0h and 18\u2009h following extubation. POH was defined as an IOP above 25\u2009mmHg (POH25). In addition, the number of patients with an IOP exceeding 20\u2009mmHg was analyzed (POH20). POH20 occurred in 33 of 54 animals (61.1%), including 19 of 25 animals (76.0%) in the control group and 14 of 29 animals (55.2%) in the treatment group. POH25 occurred in 23 of 44 animals (52.3%), including 13 of 25 animals (52.0%) in the control group and 10 of 29 animals (34.5%) in the treatment group. Paracetamol administration showed a significant positive effect on reducing the incidence of POH20 (p\u00a0=\u00a0.048), but not POH25 (p\u00a0=\u00a0.221). When comparing groups, treatment with paracetamol showed a statistically significant reduction in the incidence of POH20, although no differences were observed in the incidence of POH25 between groups. Further studies are warranted to explore whether alternative drug regimes or routes of administration can provide enhanced efficacy in the prevention of POH25.\n\nID: 42539294\nTitle: Differences in Health-Related Lifestyle Behaviors and Psychological Health Between Two Cohorts in Their 20s: The Korea Nurses' Health Study.\nAbstract: To compare health-related lifestyle behaviors and psychological health between two cohorts of individuals in their 20 s and to examine factors associated with these outcomes using data from the Korea Nurses' Health Study. A secondary analysis of nationwide cohort data from registered nurses in their 20s during the 1st (2013-2014; n = 12,055) and 13th (2024; n = 4,007) surveys. Logistic and linear regression analyses examined between-cohort differences in health-related lifestyle behaviors and psychological health. In comparison with the 1st-survey group, the 13th-survey group demonstrated higher human papillomavirus (HPV) vaccination rates (odds ratio [OR] = 1.10, 95% confidence interval [CI] = 1.01-1.20), later age at first alcohol consumption (regression coefficient [B] = 0.86, 95% CI = 0.76-0.95), and lower alcohol consumption frequency (B = -0.08, 95% CI = -0.08-0.00). In contrast, smoking-related behaviors worsened in the 13th-survey group. Regular acetaminophen use was lower in the 13th-survey group (OR = 0.55, 95% CI = 0.48-0.63). The 13th-survey group showed higher rates of depression diagnoses (OR = 2.75, 95% CI = 2.08-3.63) and perceived stress (OR = 1.22, 95% CI = 1.11-1.34), but lower odds of moderate-to-severe depressive symptoms (OR = 0.36, 95% CI = 0.32-0.40) and sleep disturbances (OR = 0.42, 95% CI = 0.38-0.48). Over the past decade, HPV vaccination and alcohol abuse have improved in registered nurses in their 20s, but smoking and perceived stress have worsened, highlighting the need for sustained surveillance and targeted prevention policies.\n\nID: 42481203\nTitle: Comparison of a four-nerve block protocol versus adductor canal block plus local infiltration analgesia for primary total knee arthroplasty in two French private hospitals: protocol for the multicentre randomised INCA trial.\nAbstract: INCA is a multicentre, prospective, randomised, two-arm superiority trial. 100 adult patients scheduled for primary total knee arthroplasty (TKA) will be randomised 1:1 to one of two locoregional analgesia strategies: group 1 (standard strategy), single-shot adductor canal block (ACB) combined with active surgeon-administered peri-articular infiltration with ropivacaine and participant-facing sham peripheral nerve blocks; group 2 (four-nerve block strategy), single-shot ACB combined with three additional ultrasound-guided nerve blocks (lateral femoral cutaneous, obturator and infiltration between the popliteal artery and capsule of the knee (IPACK) blocks) plus sham surgical infiltration. All patients will receive general anaesthesia and identical systemic multimodal analgesia (paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), nefopam and rescue opioids) so that any between-group differences can be attributed to the allocated regional strategy. The primary outcome is global recovery at 24 hours, assessed by the Quality of Recovery-15 (QoR-15) questionnaire. Secondary outcomes include postoperative pain scores, opioid consumption, rescue analgesia including any rescue infiltration, motor function and adverse events, range of motion of the index knee, time to first ambulation, postanaesthesia care unit (PACU) stay, hospital length of stay, QoR-15 at 48 hours and Knee Injury and Osteoarthritis Outcome Score-Joint Replacement (KOOS-JR) at 1\u2009month. INCA is a multicentre, prospective, randomised two-arm superiority trial. 100 adult patients scheduled for primary TKA will be randomised 1:1 to one of two locoregional analgesia strategies: group 1 (standard strategy), single-shot ACB combined with surgeon-administered peri-articular infiltration; group 2 (four-nerve block strategy), single-shot ACB combined with three additional ultrasound-guided nerve blocks (lateral femoral cutaneous, obturator and IPACK blocks) without active infiltration. Participant-facing sham procedures will be used to preserve blinding. All patients will receive general anaesthesia and identical systemic multimodal analgesia (paracetamol, NSAIDs, nefopam and rescue opioids) so that any between-group differences can be attributed to the regional strategy. The primary outcome is global recovery at 24 hours, assessed by the QoR-15 questionnaire. Secondary outcomes include postoperative pain scores, opioid consumption, rescue analgesia including any rescue infiltration, motor function and adverse events, range of motion of the index knee, time to first ambulation, PACU stay, hospital length of stay, QoR-15 at 48 hours and KOOS-JR at 1\u2009month. The study protocol has been approved by the regional ethics committee (Comit\u00e9 de Protection des Personnes). All participants provide written informed consent.

Consequently, the profile of pharmaceuticals in the environment (PiE) may undergo dynamic temporal changes, posing a significant challenge to eco-pharmacovigilance (EPV), a specialized branch of pharmacovigilance focused on detecting, evaluating, understanding, and preventing the adverse environmental effects of pharmaceuticals. Based on data extracted from 89 studies published between 2014 and 2025, this review conducts a focused comparison of the occurrence patterns of 43 selected typical anti-COVID-19 drugs (20 antibacterials, 11 antivirals, and 12 anti-inflammatory pharmaceuticals) as contaminants in distinct regions across China's seven major river basins before, during, and after the pandemic. The need of dynamic EPV was then analyzed. Before the COVID-19 outbreak, erythromycin, ampicillin, roxithromycin, and acetaminophen dominated the PiE profile in terms of reported maximum residual concentrations; during the pandemic lockdown, ciprofloxacin, ofloxacin, azithromycin, and ketoprofen were identified as the top-priority anti-COVID-19 PiE; after the pandemic, azithromycin, norfloxacin, ofloxacin, ciprofloxacin, and roxithromycin remained the dominant PiE. Residual levels of individual PiE at the same location varied noticeably across the three periods. Results revealed highly distinct regional and temporal variations in surface freshwater pollution by these COVID-19-associated PiE across the three periods, with no consistent regularity observed, thereby further highlighting the necessity of implementing EPV in a \"dynamic\" manner. Drawing on the framework of dynamic pharmacovigilance, the implementation of dynamic EPV can be promoted by establishing a dynamic watch-list mechanism, clarifying stakeholder roles, and advancing supportive policies and technological platforms, so as to enable adaptive interventions for the timely management of event-driven pharmaceutical pollution.\n\nID: 42319619\nTitle: Comparison of three therapeutic methods of transcutaneous electrical nerve stimulation, embedding acupuncture, and drug therapy on interleukin-6 and pain levels in patients with knee osteoarthritis.\nAbstract: Knee osteoarthritis (KOA) significantly impairs quality of life, yet conventional pharmacotherapy often provides inadequate symptom control with notable adverse effects. This randomized controlled trial compared thread embedding acupuncture (TEA), transcutaneous electrical nerve stimulation (TENS), and conventional drug therapy on pain, functional disability, quality of life, and serum interleukin-6 (IL-6) levels in KOA patients. Seventy-two patients aged 50-65\u00a0years with unilateral KOA (Kellgren-Lawrence grades 2-3) were randomly allocated to (1) single TEA session at ten acupoints (n\u2009=\u200924), (2) TENS therapy (50-100\u00a0Hz, 30\u00a0min, four sessions/week) for 4\u00a0weeks (n\u2009=\u200924), or (3) ibuprofen 400\u00a0mg twice daily for 4\u00a0weeks (n\u2009=\u200924). All received acetaminophen 325\u00a0mg daily. Primary outcomes were pain intensity (visual analogue scale) and serum IL-6 levels. Secondary outcomes included WOMAC index and WHOQOL-BREF scores. Assessments occurred at baseline, week 4, and week 12. Data were analyzed using repeated-measures ANOVA and ANCOVA adjusting for baseline age and IL-6. At week 12, TEA showed superior pain reduction (-\u20091.75 [95% CI:\u2009-\u20092.28 to\u2009-\u20091.21], p\u2009<\u20090.001) versus TENS (-\u20090.72 [95% CI:\u2009-\u20091.25 to\u2009-\u20090.15], p\u2009=\u20090.01) and drug therapy (0.33 [95% CI:\u2009-\u20090.53 to 1.20], p\u2009=\u20090.45). Quality of life improvements were greatest with TEA (12.83 [95% CI: 6.70 to 18.95], p\u2009<\u20090.001) compared to TENS (5.20 [95% CI: 0.41 to 10.00], p\u2009=\u20090.03) and drug therapy (-\u20091.25 [95% CI:\u2009-\u20097.18 to 4.68], p\u2009=\u20090.68). TEA and TENS significantly reduced WOMAC scores (-\u200916.58 and\u2009-\u200911.33, both p\u2009<\u20090.001), unlike drug therapy. Serum IL-6 increased significantly in the TEA group (3.20\u00a0pg/mL [95% CI: 1.74 to 4.66], p\u2009<\u20090.001) but not in TENS or drug therapy groups. A single TEA session provides superior and sustained improvements in pain, function, and quality of life compared to 4 weeks of TENS or drug therapy in KOA patients. Clinical benefits were associated with elevated serum IL-6, suggesting immunomodulatory mechanisms involving tissue repair pathways. TEA represents a promising integrative approach for KOA management, warranting larger trials with extended follow-up. Key Points \u2022 Pain control in knee osteoarthritis, a common disease. \u2022 Conventional treatments (such as TENS and medication) have high costs and side effects. \u2022 The use of acupuncture and embedding (TEA) can treat pain without any specific complications. \u2022 It is also important to examine IL-6 as a factor for which anti inflammatory effects were observed in our study and some studies.\n\nID: 42244377\nTitle: Three-dimensional cell-culture systems using nanofibrillated bacterial cellulose restores drug metabolism activity in HepG2 hepatocellular carcinoma cells.\nAbstract: Three-dimensional (3D) culture more faithfully reproducesin vivo-like cell interactions and functions than conventional two-dimensional (2D) monolayers. Although HepG2 cells are widely used in drug discovery, their 2D cultures exhibit low expression of drug-metabolizing enzymes such as cytochrome P450s (CYPs), limiting utility for toxicity and pharmacokinetic studies. Nano-fibrillated bacterial cellulose (NFBC) is a unique biomaterial that features exceptional homogeneity, high purity, and excellent biocompatibility. We recently employed two NFBC-based 3D culture systems: the Suspension and the OnGel methods. However, the capacity of NFBC to improve hepatocyte-specific functions has yet to be systematically explored. In this study, we aimed to establish a 3D culture platform for HepG2 cells using NFBC to restore hepatic functionality, and drug-metabolizing activity in particular, via comparison with conventional 2D monolayers. Both of these 3D culture systems produced viable HepG2 spheroids with good proliferation. Exploratory microarray profiling suggested broad upregulation of multiple absorption, distribution, metabolism and excretion (ADME) genes in the HepG2 spheroids. Among these, the enzyme Cytochrome P450 3A4 (CYP3A4) showed a significant increase in protein expression and in enzymatic activity in the HepG2 spheroids, which was functionally confirmed by acetaminophen (APAP) toxicity via its bioactivation into toxic metabolite. In addition, the HepG2 spheroids displayed reduced sensitivity to the anticancer drug doxorubicin compared to 2D monolayer. Collectively, these findings demonstrate that NFBC-based 3D culture systems effectively restore liver-specific functions in HepG2 cells, which results in HepG2 spheroids with metabolic competence and physiologically relevant drug responses, and could offer a promising tool for high-throughputin vitrodrug screening.\n\nID: 42063317\nTitle: Paracetamol prescribing to small animals by veterinarians in Australia and New Zealand.\nAbstract: To describe the prescribing patterns of paracetamol by veterinarians in Australia and New Zealand. An online survey was created and distributed to veterinarians in Australia and New Zealand over a 3-month period (July-October 2024). Survey questions addressed the respondent's veterinary education and qualifications, career history, paracetamol prescription characteristics and personal perceptions on paracetamol usage in small animals. A total of 1035 veterinarians completed the survey, with responses from 1025 participants included in the analysis. Most veterinarians (991/1022, 97.0%) reported having prescribed or recommended paracetamol for use in small animals, most commonly for dogs (980/985, 99.5%). This proportion did not differ significantly between veterinarians with postgraduate qualifications (384/395; 97.2%) and those without (607/627; 96.8%) (P\u2009=\u20090.86, chi-square test). Most respondents (80.9%) indicated they were more likely to prescribe paracetamol now compared to a decade ago. Most respondents reported prescribing paracetamol twice daily: 545/900 (55.1%) at 10\u2009mg/kg, 350 (35.4%) at 15\u2009mg/kg and 95 (9.6%) at 20\u2009mg/kg. More veterinarians reported prescribing paracetamol as an analgesic 987/990 (99.7%) than as an antipyretic 314 (31.7%). Prescription of paracetamol for both acute and chronic pain was reported by most veterinarians 778/984 (79.1%). 96.5% of veterinarians reported not observing adverse effects when prescribing paracetamol. The majority of veterinarians responding to our survey prescribe paracetamol to dogs and generally perceived it as safe. Nonetheless, the widespread prescribing of paracetamol among veterinarians in Australia and New Zealand should not be interpreted as an endorsement of use or proof of efficacy for analgesia in dogs. Isolated reports of prescription to cats suggest areas where further education is warranted given the risk of life-threatening paracetamol toxicity in cats.\n\nID: 42062544\nTitle: Drug supply shortages and their perceived consequences for patients: a questionnaire survey of German and Austrian physicians.\nAbstract: Drug supply shortages are a recurring issue in developed countries, with consequences for patients even before the COVID-19 pandemic. Questions arise regarding the effectiveness and tolerability of alternative treatments chosen by physicians due to these shortages. To answer these questions, a survey for practicing physicians was distributed to medical associations in Germany and Austria and conducted from November 2022 to January 2024. 895 physicians responded to the survey. The survey targeted 20 drugs with known supply shortages, namely amoxicillin, amoxicillin/clavulanic acid, penicillin V (phenoxymethylpenicillin), cefuroxime, cefaclor, erythromycin, cotrimoxazole, ibuprofen, paracetamol, urapidil, metoprolol, amlodipine, candesartan, tamoxifen, methotrexate, fluoxetine, lorazepam, human insulin, salbutamol and prednisolone. Physicians most frequently chose a different antibacterial drug (>\u200960% of the physicians), while for analgesics, they more often used a different dosage form of the same drug (>\u200933%). For antihypertensive drugs, physicians more often chose a different dosage of the same drug. In many cases, alternative antibiotics were chosen that carried a greater risk of antimicrobial resistance than the antibiotic originally intended. The treatment success for replacing antibacterials and analgesics with a different drug was rated with 4-5 on a predefined scale of 1 (very poor) to 6 (very good) in comparison to the original drug. Using the same drug in a different dosage/dosage form was also around 4-5/6 effective. Supply shortages can foster antimicrobial resistance through the use of antibacterials with a higher potential for resistance. The success of alternative treatments was not always considered to be very good in comparison to the original medication.\n\nID: 41928306\nTitle: Comparison of two targeted rescue treatments after the first week of expectant managment for very preterm infants with hemodynamically significant patent ductus arteriosus: a prospective study.\nAbstract: BACKGROUND : To investigate the clinical value of early expectant management of very preterm infants with hemodynamically significant patent ductus arteriosus (hsPDA), and the efficacy and safety of rescue treatment with oral acetaminophen or high-dose ibuprofen. METHODS: The very preterm infants with hsPDA (gestational age \u2264 32 weeks and age 4-6 days) who were admitted to the neonatal intensive care unit of Xuzhou Central Hospital between February 2022 and December 2024 were enrolled in the study. If the patient still met the diagnostic criteria of hsPDA after 3-4 days of expectant management, the rescue treatment shall be given. They were randomly divided into the acetaminophen group (oral acetaminophen 15 mg/kg, once every 6 hours for 3 days) and the high-dose ibuprofen group (oral ibuprofen 20 mg/kg for the first time, 10 mg/kg for the 24 hours and the 48 hours respectively). Before and after treatment, routine blood tests, biochemical items (including serum Cystatin C, serum creatinine, alanine aminotransferase and total serum bilirubin), urinary Cystatin C, B-type natriuretic peptide, and fecal occult blood were measured; bedside echocardiography and brain standard ultrasound were performed; and urine output and complications were recorded. The data were analyzed by t-test, rank sum test and chi-square test with SPSS 20.0 statistical software. RESULTS: 167 (54.4%) of 307 very preterm infants with hsPDA showed spontaneous closure in the first 7-10 days of life. There was no significant difference in the success rate of rescue treatment between the acetaminophen group and the high-dose ibuprofen group [82.0% (50/61) vs. 77.8% (49/63), P=0.561]. During rescue treatment, the upper gastrointestinal bleeding rate, positive fecal occult blood tests and oliguria rate of high-dose ibuprofen group were higher than those of the acetaminophen group, but the difference was not statistically significant (P>0.05). The incidence of stage \u2161-\u2162 necrotizing enterocolitis and stage \u2162-\u2163 intraventricular hemorrhage in the two groups were lower, and the difference was not statistically significant (P>0.05). After rescue treatment, the serum Cystatin C of high-dose ibuprofen group was higher than that of acetaminophen group [(1.66\u00b10.30) mg/L vs. (1.55\u00b10.24) mg/L], the urinary Cystatin C of high-dose ibuprofen group was higher than that of acetaminophen group [(80.00\u00b132.96) ng/mL vs. (66.50\u00b126.77) ng/mL], and the 24-hours urine output was lower than that of acetaminophen group [(2.66\u00b11.32) ml/(kg\u2022h) vs. (3.29\u00b11.15) ml/(kg\u2022h)], with statistical significance (P=0.018, 0.014, 0.290). After rescue treatment, there were no significant differences in serum creatinine, platelet count, B-type natriuretic peptide, alanine aminotransferase, and total serum bilirubin between the two groups (P>0.05). CONCLUSION: In the early stage (7-10 days after birth) of very preterm infants with hsPDA, the spontaneous closure rate of hsPDA during expectant management can reach more than 50%. After the failure of expectant management, rescue treatment with oral acetaminophen or high-dose ibuprofen can be started on the 7th to 10th day after birth, and the success rate is about 80%, and was relatively safe. The effect of oral high-dose ibuprofen on renal function may be greater than that of acetaminophen. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCRT2200056444.

This exploratory study evaluated whether three non-steroidal anti-inflammatory drugs (NSAIDs)-acetylsalicylic acid, ibuprofen, and diclofenac (100 \u00b5M)-modulate pathogenicity-related processes in A. castellanii and explored the involvement of a gp63-like protein during encystment and adhesion. Trophozoites were continuously exposed to each drug and analyzed for adhesion, migration on host-derived discontinuous brain micropatterns, encystment efficiency, and parasite-induced cytoskeletal remodeling in MDCK epithelial cells. In silico docking was performed to assess potential drug-protein interactions. Drug exposure reduced adhesion with maximal inhibition at 60 min. After 1 h, migration decreased by 49%, 64%, and 38%, and encystment was reduced by 50%, 85%, and up to 90%, respectively, in cultures treated with acetylsalicylic acid, ibuprofen, and diclofenac. Co-incubation with untreated trophozoites lowered actin fluorescence to approximately 50%, whereas drug-treated co-cultures preserved fluorescence near control levels. Colocalization analysis showed increased spatial overlap between gp63-like protein and F-actin in cysts (~40%) and migrating trophozoites (~20%) compared with non-stimulated forms (~3.8%). Collectively, these findings suggest that NSAID-sensitive pathways influence host interaction, migration, and encystment in A. castellanii and allow for the proposal of gp63-like protein as a putative molecular component of the NSAIDs sensitive pathways.\n\nID: 41884978\nTitle: Comparison of caudal and retrolaminar blocks for postoperative analgesia in pediatric orchidopexy: a randomized controlled trial.\nAbstract: Lower abdominal surgeries in children are associated with significant postoperative pain. While caudal block (CB) is widely used, ultrasound-guided truncal blocks such as retrolaminar block (RLB) may provide more targeted and prolonged analgesia. In this double-blind, randomized controlled trial conducted at two tertiary hospitals (March 1-September 1, 2025), children aged 1-7 years (ASA I-II) scheduled for unilateral orchidopexy were randomized to RLB or CB. CB received 0.125% bupivacaine 1 mL/kg (max 20 mL); RLB received 0.25% bupivacaine 0.1 mL/kg, both under standardized general anesthesia with intraoperative IV paracetamol (10 mg/kg). FLACC scores were recorded at 30 min and 1, 2, 4, 6, 12, and 24 h. Rescue analgesia was IV paracetamol for FLACC 2-4 and IV tramadol for FLACC >4. Primary outcome was analgesic efficacy (FLACC at 12th hour). Secondary outcomes were time to first analgesic and total consumption within 24 h. Sixty-two patients were analyzed (N.=31 per group); baseline demographics did not differ. RLB yielded lower FLACC scores at 6 h (P=0.002), 12 h (P=0.007), and 24 h (P=0.018), with no difference at 30 min or 1 h (P>0.05). Time to first analgesic was longer with RLB (P<0.001), and total 24-h consumption was lower (P=0.001). Fewer patients required rescue analgesia with RLB (3/31) than CB (14/31). No major block-related complications occurred. In pediatric orchidopexy, RLB provided superior and more durable analgesia than CB, reduced 24-h analgesic requirements, and delayed first rescue dosing without major complications, supporting its role within opioid-sparing pediatric ERAS pathways.\n\nID: 36718573\nTitle: The analysis of reason for the presence and treatment of chronic inflammation of the paranasal sinuses in own material.\nAbstract: SummaryIntroduction. . The aim of the study was the analysis of reasons for the occurrence and treatment results of chronic inflammation of the paranasal sinuses in own materail. The study was performed on 520 women aged 18 - 87 and 789 men aged 19-85, diagnosed and treated for the chronic inflammation of the paranasal sinuses in 2016 - 2020. The analysis was based on disease medical history, taking into account: gender; age of patients; type of symptoms; allergy diagnosis; probable cause of inflammation; type of anatomical anomalies; assessment of the advancement of lesions based on CT images in the Lund- Mackay scale; number of operations; histopathological result of the removed lesions; complications that occured after surgical treatment.ResultsThe study showed that the hospitalized patients were most often aged 41-50, 51-60 and 31-40 among women and men aged 51-60, 41-50 and 31- 40 . The results of allergological diagnostics among patients with chronic inflammation of the paranasal sinuses showed that women were most often allergic to pyralgin + ketonal + paracetamol + ibuprofen in 4.50 % , to penicillins in 1.07 % and to house dust saprophytes in 0.92%, while among men, positive reactions were found in 3.36 % for pyralgin + ketonal + paracetamol + ibuprofen, 0.99% for house dust saprophytes and 0.92% for cats and dogs fur. Absence of anatomical anomalies was found among 20.75 % of woman and 26.36 % of men, but most often they occurred in the form of nasal septal curvature and excessively dilated middle nasal turbinate. In the histopathological examination of the lesions from the paranasal sinuses, the following were found: chronicinflammation of mucous membrane, chronic polypoid inflammation, chronic cystic inflammation and chronic allergic inflammation. The main symptoms among patients with chronic inflammation of paranasal sinuses were: nasal congestion + rhinorrhea, nasal congestion + rhinorrhea + smell impairment and nasal congestion + rhinorrhea+ headache. The most common probable causes for chronic inflammation of nasal sinuses among the examined patients were: anatomical anomalies, allergies, irritant factors, including tobacco smoke. Depending on the assessment of the severity of changes in the paranasal sinuses according to the Lund- Mackay scale, it appears that medium and large inflammatory lesions prevailed in the examined patients. reason/cause, occurrence, treatment results, chronic inflammation of the paranasal sinuses.\n\nID: 36402479\nTitle: Treatment of Pain in Rats, Mice, and Prairie Dogs.\nAbstract: Recent myomorph and scuiromorph rodent analgesia studies are reviewed and evaluated for potential clinical application. Differences between laboratory animal studies and clinical use in diseased animals are discussed. Analgesia classes reviewed include local anesthetics, nonsteroidal anti-inflammatories, acetaminophen, opioids, and adjuvants such as anticonvulsants. Routes of administration including sustained-release mechanisms are discussed, as are reversal agents. Drug interactions are reviewed in the context of beneficial multimodal analgesia as well as potential adverse effects. Dosage recommendations for clinical patients are explored.\n\nID: 31900324\nTitle: Comparing paracetamol/codeine and meloxicam for postoperative analgesia in dogs: a non-inferiority trial.\nAbstract: There are limited published data on the analgesic efficacy of paracetamol/codeine in dogs. Prospective, randomised, blinded, positive-controlled clinical trial with 70 dogs (paracetamol/codeine, n=46; meloxicam, n=24) undergoing surgery. Drugs were administered orally 2 hours before and for 48\u2009hours after surgery at the licensed dose. Anaesthesia was standardised. Dogs received buprenorphine 6 hourly for the first 24\u2009hours after surgery. Outcome assessments were made pretrial and at regular intervals up to 48\u2009hours after extubation and comprised the Glasgow Composite Measure Pain Score-Short Form, visual analogue scale for sedation and inflammation and mechanical nociceptive threshold (MNT). Non-inferiority of paracetamol/codeine compared with meloxicam was defined using a non-inferiority margin (\u0394) against the 95 per cent confidence interval of the difference between the treatment means. Pain scores were low in both treatment groups. With the exception of MNT all upper 95 per cent confidence intervals for the differences between outcome variable treatment means were within +\u0394 for each variable, establishing non-inferiority for each outcome variable. Paracetamol/codeine is a useful perioperative analgesic that within the context of the perioperative analgesia regimen studied (methadone premedication, buprenorphine for the first 24\u2009hours after surgery) shows non-inferiority to the NSAID meloxicam.\n\nID: 31073006\nTitle: Paracetamol toxicity in dogs.\nAbstract: \n\nID: 27412988\nTitle: From Genotype to Phenotype: Nonsense Variants in SLC13A1 Are Associated with Decreased Serum Sulfate and Increased Serum Aminotransferases.\nAbstract: Using genomic applications to glean insights into human biology, we systematically searched for nonsense single nucleotide variants (SNVs) that are rare in the general population but enriched in the Old Order Amish (Amish) due to founder effect. We identified two nonlinked, nonsense SNVs (R12X and W48X) in SLC13A1 (allele frequencies 0.29% and 0.74% in the Amish; enriched 1.2-fold and 3.7-fold, compared to the outbred Caucasian population, respectively). SLC13A1 encodes the apical sodium-sulfate cotransporter (NaS1) responsible for sulfate (re)absorption in the kidneys and intestine. SLC13A1 R12X and W48X were independently associated with a 27.6% (P = 2.7 \u00d7 10(-8)) and 27.3% (P = 6.9 \u00d7 10(-14)) decrease in serum sulfate, respectively (P = 8.8 \u00d7 10(-20) for carriers of either SLC13A1 nonsense SNV). We further performed the first exome- and genome-wide association study (ExWAS/GWAS) of serum sulfate and identified a missense variant (L348P) in SLC26A1, which encodes the basolateral sulfate-anion transporter (Sat1), that was associated with decreased serum sulfate (P = 4.4 \u00d7 10(-12)). Consistent with sulfate's role in xenobiotic detoxification and protection against acetaminophen-induced hepatotoxicity, SLC13A1 nonsense SNV carriers had higher aminotransferase levels compared to noncarriers. Furthermore, SLC26A1 L348P was associated with lower whole-body bone mineral density (BMD) and higher serum calcium, consistent with the osteochondrodysplasia exhibited by dogs and sheep with naturally occurring, homozygous, loss-of-function mutations in Slc13a1 This study demonstrates the power and translational potential of systematic identification and characterization of rare, loss-of-function variants and warrants additional studies to better understand the importance of sulfate in human physiology, disease, and drug toxicity.\n\nID: 25417837\nTitle: Evaluation of the use of G\u00f6ttingen minipigs to predict food effects on the oral absorption of drugs in humans.\nAbstract: This study investigated the oral absorption of drugs in minipigs to predict food effects in man. The protocol was based on a previously described model in dogs and further investigated the food source (i.e., US FDA breakfast or a nutritional drink) and food quantities. Two poorly soluble compounds were investigated [pravastatin (negative food effect) and atazanavir (positive food effect)] in G\u00f6ttingen minipigs after seven different food regimens. The gastric emptying rate was evaluated by coadministration of acetaminophen. In short, the results demonstrated longer gastric emptying times in minipigs when compared with humans, within a range from 2.3 to 8.4 h dependent on the food regimen. There were no significant differences in drug absorption between fed and fasted state for the two compounds. The study showed that the dog protocol could not be transferred directly to minipigs, but needs further investigation and adjustments in order to get a valid model using G\u00f6ttingen minipigs for the evaluation of food effects on drug absorption in humans.\n\nID: 21389119\nTitle: Influence of non-steroidal anti-inflammatory drugs on organic anion transporting polypeptide (OATP) 1B1- and OATP1B3-mediated drug transport.\nAbstract: The transporter-mediated uptake of drugs from blood into hepatocytes is a prerequisite for intrahepatic drug action or intracellular drug metabolism before excretion. Therefore, uptake transporters, e.g., members of the organic anion transporting polypeptide (OATP) family are important determinants of drug pharmacokinetics. Highly and almost exclusively expressed in hepatocytes are the OATP family members OATP1B1 (SLCO1B1) and OATP1B3 (SLCO1B3). Drug substrates of OATP1B1 and OATP1B3 include antibiotics and HMG-CoA reductase inhibitors (statins). It has been demonstrated that administration of two or more drugs that are substrates for these hepatic uptake transporters may lead to transporter-mediated drug-drug interactions, resulting in altered transport kinetics for drug substrates. In this study we investigated whether non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol interact with OATP1B1 and OATP1B3 using the standard substrate BSP and the drug substrate pravastatin. Using human embryonic kidney cells stably expressing OATP1B1 or OATP1B3, we demonstrated that bromosulfophthalein uptake was inhibited by diclofenac, ibuprofen. and lumiracoxib. Of interest, pravastatin uptake was stimulated by these NSAIDs, and for ibuprofen we determined activation constants (EC\u2085\u2080 values) of 64.0 and 93.1 \u03bcM for OATP1B1- and OATP1B3-mediated uptake, respectively. Furthermore, we investigated whether NSAIDs were also substrates for OATP1B1 and OATP1B3 and demonstrated that only diclofenac was significantly transported by OATP1B3, whereas all other NSAIDs investigated were not substrates for these uptake transporters. These results demonstrated that drugs may interact with transport proteins by allosteric mechanisms without being substrates and, therefore, not only uptake inhibition but also allosteric-induced modulation of transport function may be an important mechanism in transporter-mediated drug-drug interactions.\n\nID: 16248834\nTitle: An old drug with a new purpose: cardiovascular actions of acetaminophen (paracetamol).\nAbstract: For over 50 years, acetaminophen (paracetamol) has been a staple in industrialized and non-industrialized countries for the treatment of pain and fever. Although its precise mechanisms of action are not known, the drug generates dose-dependent reduction in circulating prostaglandins, inhibits myeloperoxidase and the oxidation of lipoproteins, and appears to confer cardioprotection by blocking the effects of hydroxyl radical, peroxynitrite, and hydrogen peroxide. The drug might inhibit cyclooxygenase, although its ultimate target(s) is (are) still unclear. Sadly, since most investigations of acetaminophen have focused on its analgesic/antipyretic properties and hepatotoxicity, the effects of the drug on other mammalian organ systems, including the heart and circulation, have been ignored. Recently, work in our laboratory has shown acetaminophen to have a protective role in the injured mammalian myocardium. The cardioprotection was first observed in isolated, perfused guinea pig hearts subjected to ischemia-reperfusion injury. Hearts pretreated with acetaminophen recovered greater ventricular function and exhibited improved myofibrillar ultrastructure when compared to vehicle-treated hearts. More recent in vitro investigations have suggested protective roles for acetaminophen in barbiturate-induced arrhythmogenesis and myocardial hypoxia-reoxygenation injury. We have also extended our work to the in vivo arena. There, we found that acetaminophen reduced infarct size in dogs exposed to 60 minutes regional myocardial ischemia and 180 minutes reperfusion. We invite and encourage readers of this review to repeat/duplicate our experiments. Such work is needed to either challenge or support our findings. Further, more clinically-relevant work depends on these basic and related translational experiments.\n\nID: 15885459\nTitle: The delayed dissolution of paracetamol products in the canine fed stomach can be predicted in vitro but it does not affect the onset of plasma levels.\nAbstract: Although it is generally believed that paracetamol can be used as a marker of gastric emptying, there have been reports in the literature that show delayed dissolution of immediate release paracetamol tablets using standard in vitro setups and food-simulating media, delayed disintegration of paracetamol products in the fed stomach, and no correlation of paracetamol absorption with gastric emptying in the fed state. In this study, we confirmed that dissolution of Panodil and Apotel tablets is delayed in food-simulating media regardless of the in vitro hydrodynamics and on a formulation dependent manner. Further, we assessed the usefulness of in vitro dissolution data in the prediction of delayed disintegration time in the fed stomach and we examined the importance of delayed gastric disintegration on the onset of plasma levels using the canine model. In vitro dissolution data in cow's milk reflected the delayed disintegration of Panodil tablets in the fed stomach. In vitro dissolution of Apotel tablets in milk was delayed less than of Panodil and the effect of dosing conditions on the in vivo disintegration was not apparent. However, for the products tested in this study, there was no correlation between intragastric disintegration and onset of plasma levels probably because gastric emptying in also delayed in the fed state.\n\nID: 15256373\nTitle: Acetaminophen and myocardial infarction in dogs.\nAbstract: The hypothesis that acetaminophen can reduce necrosis during myocardial infarction was tested in male dogs. Two groups were studied: vehicle- (n=10) and acetaminophen-treated (n=10) dogs. All dogs were obtained from the same vendor, and there were no significant differences in their ages (18 +/- 2 mo), weights (24 +/- 1 kg), or housing conditions. Selected physiological data, e.g., coronary blood flow, nonspecific collateral flow, epicardial temperature, heart rate, systemic mean arterial pressure, left ventricular developed pressure, the maximal first derivative of left ventricular developed pressure, blood gases, and pH, were collected at baseline and during regional myocardial ischemia and reperfusion. There were no significant differences in coronary blood flow, nonspecific collateral flow, epicardial temperature, heart rate, systemic mean arterial pressure, or blood gases and pH between the two groups at any of the three time intervals, even though there was a trend toward improved function in the presence of acetaminophen. Infarct size, the main objective of the investigation, was markedly and significantly reduced by acetaminophen. For example, when expressed as a percentage of ventricular wet weight, infarct size was 8 +/- 1 versus 3 +/- 1%(P <0.05) in vehicle- and acetaminophen-treated hearts, respectively. When infarct size was expressed as percentage of the area at risk, it was 35 +/- 3 versus 13 +/- 2% (P <0.05) in vehicle- and acetaminophen-treated groups, respectively. When area at risk was expressed as percentage of total ventricular mass, there were no differences in the two groups. Results reveal that the recently reported cardioprotective properties of acetaminophen in vitro can now be extended to the in vivo arena. They suggest that it is necessary to add acetaminophen to the growing list of pharmaceuticals that possess cardioprotective efficacy in mammals.\n\nID: 35033846\nTitle: Propacetamol in dogs: First description of its pharmacokinetics after intravenous and oral administration.\nAbstract: Propacetamol is a prodrug form of paracetamol (APAP) licensed for human use as a pain reliever in postoperative care. It is prescribed if APAP cannot be administered orally or rectally to a patient and for patients in whom nonsteroidal anti-inflammatory drugs are contraindicated. In this study, we aimed to quantify the pharmacokinetics of APAP and its metabolites, paracetamol sulfate (PS), paracetamol glucuronide (PG), and N-acetyl-p-benzoquinone imine (NAPQI), after a single oral and intravenous (IV) administration of 30\u00a0mg/kg of propacetamol to six healthy adult Labrador dogs according to a 2\u00a0\u00d7\u00a02 crossover study. The analyses were performed using a validated HPLC-MS/MS method. PS and PG exposures were higher than that of APAP, while NAPQI concentrations were constantly below the detection limit of the analytical method. IV propacetamol administration produced 30% more APAP than oral administration. However, propacetamol released a significantly lower amount of active moiety in dogs than in humans. The propacetamol dose administered in this study did not produce plasma APAP concentrations above the threshold sufficient to provide analgesia in adult humans (4\u00a0\u03bcg/mL). In conclusion, direct IV injection of APAP instead of propacetamol might be a better clinical option for pain relief in dogs.\n\nID: 33182644\nTitle: Bioavailability of the Common Cold Medicines in Jellies for Oral Administration.\nAbstract: Jellies for oral administration have been suggested as alternative dosage forms to conventional tablets for improved palatability and compliances for pediatric and geriatric patients. To evaluate the effect of jelly formulation on the bioavailability of cold medicines, two types of jellies were prepared for a fixed-dose combination of acetaminophen (AAP), chlorpheniramine maleate (CPM), dextromethorphan hydrobromide (DMH), and dl-methylephedrine hydrochloride (MEH). Jelly-S and Jelly-H were fabricated using carrageenan and locust bean gum in the absence and presence of xanthan gum, respectively. In vitro dissolution and in vivo absorption of the four drugs in the jellies were compared with other conventional formulations, a syrup and two types of immediate-release (IR) tablets with different hardness, Tablet-S (15 kPa) and Tablet-H (20 kPa). All the formulations exhibited more than 80% dissolution rate within 2 h even though the syrup, Jelly-S, and Tablet-S showed higher 30-min dissolution compared to Jelly-H and Tablet-H. The dissolution rates from the jellies decreased with increasing pH, which resulted in the slowest dissolution in pH 6.8 compared to the syrup and IR tablets. When administered orally to beagle dogs, all five formulations were determined not to be bioequivalent. However, Jelly-S and Jelly-H showed 0.82-1.05 of the geometric mean ratios (GMRs) of AUC0-t for all four drugs compared to the syrup suggesting comparable absorption. In two IR tablets, GMRs of AUC0-t were in a range of 0.55-0.95 indicating a tendency of lower absorption than the syrup and jellies. In conclusion, jelly can be a patient-centered formulation with comparable bioavailability to syrup.\n\nID: 32059002\nTitle: Clinical evaluation of postoperative analgesia, cardiorespiratory parameters and changes in liver and renal function tests of paracetamol compared to meloxicam and carprofen in dogs undergoing ovariohysterectomy.\nAbstract: In veterinary medicine, the administration of nonsteroidal anti-inflammatory analgesics (NSAIDs) for the control of postsurgical pain in dogs and cats is common given the anti-inflammatory, analgesic, and antipyretic effects of these drugs. This study compared the serum biochemical changes and postoperative analgesic effects of paracetamol, meloxicam, and carprofen in bitches submitted to an ovariohysterectomy using the Dynamic Interactive Visual Analog Scale (DIVAS) and Pain Scale of the University of Melbourne (UMPS) scoring systems. Thirty bitches of different breeds underwent elective ovariohysterectomies and were randomly assigned to one of three treatment groups: a paracetamol group [15 mg kg-1 intravenous (IV)], a carprofen group (4 mg kg-1 IV), and a meloxicam group (0.2 mg kg-1 IV). All treatments were administered 30 minutes prior to surgery. Paracetamol was administered every 8 hours postoperatively for 48 hours total, while carprofen and meloxicam were intravenously administered every 24 hours. An evaluation of post-surgical pain was done with the DIVAS and the UMPS. The first post-surgical pain measurement was performed 1 hour after surgery and then 2, 4, 6, 8, 12, 16, 20, 24, 36, and 48 hours after surgery. All groups exhibited a gradual reduction in pain throughout the postoperative period in both scales; however, neither scale significantly differed between the three treatment groups (P > 0.05) during the 48 postoperative hours. Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy. The present study demonstrates that paracetamol may be considered a tool for the effective treatment of acute perioperative pain in dogs. Furthermore, this drug led to no adverse reactions or changes in the parameters assessed in the present study, indicating its safety.\n\nID: 26179383\nTitle: Uridine Diphosphate-Glucuronosyltransferase (UGT) Xenobiotic Metabolizing Activity and Genetic Evolution in Pinniped Species.\nAbstract: There are various interspecies differences in xenobiotic-metabolizing enzymes. It is known that cats show slow glucuronidation of drugs such as acetaminophen and strong side effects due to the UGT1A6 pseudogene. Recently, the UGT1A6 pseudogene was found in the Northern elephant seal and Otariidae was suggested to be UGT1A6-deficient. From the results of measurements of uridine diphosphate-glucuronosyltransferase (UGT) activity using liver microsomes, the Steller sea lion, Northern fur seal, and Caspian seal showed UGT activity toward 1-hydroxypyrene and acetaminophen as low as in cats, which was significantly lower than in rat and dog. Furthermore, UGT1A6 pseudogenes were found in Steller sea lion and Northern fur seal, and all Otariidae species were suggested to have the UGT1A6 pseudogene. The UGT1 family genes appear to have undergone birth-and-death evolution based on a phylogenetic and synteny analysis of the UGT1 family in mammals including Carnivora. UGT1A2-1A5 and UGT1A7-1A10 are paralogous genes to UGT1A1 and UGTA6, respectively, and their numbers were lower in cat, ferret and Pacific walrus than in human, rat, and dog. Felidae and Pinnipedia, which are less exposed to natural xenobiotics such as plant-derived toxins due to their carnivorous diet, have experienced fewer gene duplications of xenobiotic-metabolizing UGT genes, and even possess UGT1A6 pseudogenes. Artificial environmental pollutants and drugs conjugated by UGT are increasing dramatically, and their elimination to the environment can be of great consequence to cat and Pinnipedia species, whose low xenobiotic glucuronidation capacity makes them highly sensitive to these compounds.\n\nID: 24650193\nTitle: Age-related pharmacokinetic changes of acetaminophen, antipyrine, diazepam, diphenhydramine, and ofloxacin in male cynomolgus monkeys and beagle dogs.\nAbstract: 1. The pharmacokinetics of acetaminophen (marker of gastric emptying), antipyrine (marker of hepatic metabolic activity and total body water), diazepam (lipophilic and highly distributed), diphenhydramine (hepatic blood flow-limited and alpha-1 acid glycoprotein bound) and ofloxacin (renally eliminated) were evaluated in cynomolgus monkeys (3-18 years old) and beagle dogs (2-11 years old) as models in elderly persons. 2. Gastric pH fluctuated with aging in monkeys and dogs. The concentration of alpha-1 acid glycoprotein appeared to be increased by aging. There were no age-related differences in the absorption rates of the drugs under the conditions used in the study. Total body fat increased and water decreased in monkeys, but these parameters did not change in dogs. 3. Hepatic blood flow decreased in both species, but a significant decrease of hepatic clearance was only seen in monkeys. Renal clearance decreased significantly with age in monkeys and showed a tendency to decrease in dogs. 4. Age-related alterations of physiological parameters in monkeys are in agreement with clinical observations in humans, except for the lack of a change in the plasma albumin concentration. Therefore, this study suggests that monkey might be a suitable animal model for prediction of age-related changes in pharmacokinetics in humans.\n\nID: 23894158\nTitle: Highly selective bioactivation of 1- and 2-hydroxy-3-methylcholanthrene to mutagens by individual human and other mammalian sulphotransferases expressed in Salmonella typhimurium.\nAbstract: The benzylic alcohols 1- and 2-hydroxy-3-methylcholanthrene (OH-MC) are major primary metabolites of the carcinogen 3-methylcholanthrene (MC). We investigated them for mutagenicity in TA1538-derived Salmonella typhimurium strains expressing mammalian sulphotransferases (SULTs). 1-OH-MC was efficiently activated by human (h) SULT1B1 (2400 revertants/nmol), weakly activated by hSULT1C3 and hSULT2A1 (2-9 revertants/nmol), but not activated by the other hSULTs studied (1A2, 1A3, 1C2 and 1E1). Mouse, rat and dog SULT1B1 activated 1-OH-MC (8-100 revertants/nmol) with much lower efficiency than their human orthologue. The other isomer, 2-OH-MC, was activated to a potent mutagen by hSULT1A1 (4000-5400 revertants/nmol), weakly activated by hSULT1A2 or hSULT2A1 (1-12 revertants/nmol), but not activated by the other hSULTs. In contrast to their human orthologue, mouse, rat and dog SULT1A1 did not appreciably activate 2-OH-MC (<1 to 6 revertants/nmol), either. Instead, mouse and rat SULT1B1, unlike their human and canine orthologues, demonstrated some activation of 2-OH-MC (15-100 revertants/nmol). Docking analyses indicated that 1- and 2-OH-MC might bind to the active site of hSULT1A1 and hSULT1B1, but only for (S)-2-OH-MC/hSULT1A1 and (R)-1-OH-MC/hSULT1B1 with an orientation suitable for catalysis. Indeed, 1- and 2-OH-MC were potent inhibitors of the hSULT1A1-mediated sulphation of acetaminophen [concentration inhibiting the enzyme activity by 50% (IC50) 15 and 13nM, respectively]. This inhibition was weak with mouse, rat and dog SULT1A1 (IC50 \u2265 4 \u00b5M). Inhibition of the SULT1B1 enzymes was moderate, strongest for 1-OH-MC/hSULT1B1. In conclusion, this study provides examples for high selectivity of bioactivation of promutagens by an individual form of human SULT and for pronounced differences in activation capacity between orthologous SULTs from different mammalian species. These characteristics make the detection and evaluation of such mutagens extremely difficult, in particular as the critical form may even differ for positional isomers, such as 1- and 2-OH-MC. Moreover, the species-dependent differences will complicate the verification of in vitro results in animal studies.\n\nID: 22074769\nTitle: Phenacetin pharmacokinetics in CYP1A2-deficient beagle dogs.\nAbstract: Phenacetin is widely used as an in vitro probe to measure CYP1A2 activity across species. To investigate whether phenacetin can be used as an in vivo probe substrate to phenotype CYP1A2 activity in dogs, beagle dogs previously genotyped for a single nucleotide polymorphism that yields an inactive CYP1A2 protein were selected and placed into one of three groups: CC (wild-type), CT (heterozygous), or TT (homozygous mutants). The dogs were dosed with phenacetin orally at 5 and 15 mg/kg and intravenously at 15 mg/kg. Plasma samples were analyzed by liquid chromatography-tandem mass spectrometry, and phenacetin and its primary metabolite, acetaminophen, were monitored. After intravenous dosing, all groups showed similar exposure of phenacetin irrespective of genotype. After oral dosing at 15 mg/kg, the exposure of phenacetin in CC and CT dogs was similar, but phenacetin exposure was 2-fold greater in TT dogs. Exposure of the metabolite, acetaminophen, was similar in all groups; however, the mean acetaminophen/phenacetin ratio in TT dogs was 1.7 times less than that observed in CC dogs. Similar trends between the groups of dogs with respect to phenacetin exposure were also observed after a lower 5 mg/kg p.o. dose of phenacetin; however, a proportionally greater amount of acetaminophen was generated. Although oral exposure of phenacetin was 2-fold higher and acetaminophen exposure was 2-fold lower in CYP1A2-deficient (TT) dogs, these results were considered modest and suggest that phenacetin is not a selective or robust in vivo probe to measure CYP1A2 enzyme activity in the dog.\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.

An online survey was created and distributed to veterinarians in Australia and New Zealand over a 3-month period (July-October 2024). Survey questions addressed the respondent's veterinary education and qualifications, career history, paracetamol prescription characteristics and personal perceptions on paracetamol usage in small animals. A total of 1035 veterinarians completed the survey, with responses from 1025 participants included in the analysis. Most veterinarians (991/1022, 97.0%) reported having prescribed or recommended paracetamol for use in small animals, most commonly for dogs (980/985, 99.5%). This proportion did not differ significantly between veterinarians with postgraduate qualifications (384/395; 97.2%) and those without (607/627; 96.8%) (P\u2009=\u20090.86, chi-square test). Most respondents (80.9%) indicated they were more likely to prescribe paracetamol now compared to a decade ago. Most respondents reported prescribing paracetamol twice daily: 545/900 (55.1%) at 10\u2009mg/kg, 350 (35.4%) at 15\u2009mg/kg and 95 (9.6%) at 20\u2009mg/kg. More veterinarians reported prescribing paracetamol as an analgesic 987/990 (99.7%) than as an antipyretic 314 (31.7%). Prescription of paracetamol for both acute and chronic pain was reported by most veterinarians 778/984 (79.1%). 96.5% of veterinarians reported not observing adverse effects when prescribing paracetamol. The majority of veterinarians responding to our survey prescribe paracetamol to dogs and generally perceived it as safe. Nonetheless, the widespread prescribing of paracetamol among veterinarians in Australia and New Zealand should not be interpreted as an endorsement of use or proof of efficacy for analgesia in dogs. Isolated reports of prescription to cats suggest areas where further education is warranted given the risk of life-threatening paracetamol toxicity in cats.\n  --- END ACTUAL ABSTRACT FOR 42063317 ---\n\n- ERROR: You cited ID: 42176063 for the quote: \"Poisoning of companion animals resulting from exposure to analgesics intended for human use is a frequent and clinically relevant problem in veterinary practice.\"\n  FACT: Strict Misquote Detected!

This can induce severe systemic toxicity. Diagnostic confirmation can be particularly challenging in cases presenting with nonspecific clinical signs or when conventional biological samples are unavailable. This case report describes the innovative use of earwax as a non-invasive biological matrix for toxicological confirmation in veterinary medicine. A 9-year-old male mixed-breed dog was admitted following a traumatic accident and subsequent administration by its owner of a human medication containing acetaminophen and codeine. Clinical evaluation revealed lethargy, hypersalivation, hyporexia, dehydration, and neurological abnormalities. Laboratory findings demonstrated neutrophilic leukocytosis and marked increases in hepatic enzyme activities, consistent with acute hepatocellular injury. Toxicological investigation using headspace gas chromatography-mass spectrometry detected acetaminophen-related signatures in an earwax sample, supporting suspected exposure to the drug.

This can induce severe systemic toxicity. Diagnostic confirmation can be particularly challenging in cases presenting with nonspecific clinical signs or when conventional biological samples are unavailable. This case report describes the innovative use of earwax as a non-invasive biological matrix for toxicological confirmation in veterinary medicine. A 9-year-old male mixed-breed dog was admitted following a traumatic accident and subsequent administration by its owner of a human medication containing acetaminophen and codeine. Clinical evaluation revealed lethargy, hypersalivation, hyporexia, dehydration, and neurological abnormalities. Laboratory findings demonstrated neutrophilic leukocytosis and marked increases in hepatic enzyme activities, consistent with acute hepatocellular injury. Toxicological investigation using headspace gas chromatography-mass spectrometry detected acetaminophen-related signatures in an earwax sample, supporting suspected exposure to the drug. Intensive treatment was promptly initiated and included fluid therapy, antidotal treatment with N-acetylcysteine, opioid antagonism, analgesia, and supportive care. The patient showed progressive clinical improvement, with complete resolution of clinical signs and full recovery. This case highlights the significant risks of administering human medications to companion animals and underscores the need to improve owner awareness of self-medication practices.

Prospective, randomised, blinded, positive-controlled clinical trial with 70 dogs (paracetamol/codeine, n=46; meloxicam, n=24) undergoing surgery. Drugs were administered orally 2 hours before and for 48\u2009hours after surgery at the licensed dose. Anaesthesia was standardised. Dogs received buprenorphine 6 hourly for the first 24\u2009hours after surgery. Outcome assessments were made pretrial and at regular intervals up to 48\u2009hours after extubation and comprised the Glasgow Composite Measure Pain Score-Short Form, visual analogue scale for sedation and inflammation and mechanical nociceptive threshold (MNT). Non-inferiority of paracetamol/codeine compared with meloxicam was defined using a non-inferiority margin (\u0394) against the 95 per cent confidence interval of the difference between the treatment means. Pain scores were low in both treatment groups. With the exception of MNT all upper 95 per cent confidence intervals for the differences between outcome variable treatment means were within +\u0394 for each variable, establishing non-inferiority for each outcome variable.

Diabetic and non-diabetic patients (total 54 dogs) undergoing unilateral or bilateral phacoemulsification were recruited to this placebo-controlled, prospective study. The control group received 1\u2009ml/kg saline via intravenous infusion while the treatment group received 10\u00a0mg/kg paracetamol via intravenous infusion. Infusions were administered 30\u00a0min prior to surgery and repeated 12\u00a0h following initial administration. All patients received topical latanoprost at the conclusion of surgery. Intraocular pressure (IOP) was measured before premedication (baseline), and at 1\u00a0h, 3\u00a0h, 5\u00a0h and 18\u2009h following extubation. POH was defined as an IOP above 25\u2009mmHg (POH25). In addition, the number of patients with an IOP exceeding 20\u2009mmHg was analyzed (POH20). POH20 occurred in 33 of 54 animals (61.1%), including 19 of 25 animals (76.0%) in the control group and 14 of 29 animals (55.2%) in the treatment group. POH25 occurred in 23 of 44 animals (52.3%), including 13 of 25 animals (52.0%) in the control group and 10 of 29 animals (34.5%) in the treatment group. Paracetamol administration showed a significant positive effect on reducing the incidence of POH20 (p\u00a0=\u00a0.048), but not POH25 (p\u00a0=\u00a0.221). When comparing groups, treatment with paracetamol showed a statistically significant reduction in the incidence of POH20, although no differences were observed in the incidence of POH25 between groups. Further studies are warranted to explore whether alternative drug regimes or routes of administration can provide enhanced efficacy in the prevention of POH25.\n  --- END ACTUAL ABSTRACT FOR 35512023 ---\n\n- ERROR: You cited ID: 37576835 for the quote: \"The authors postulated the dog possibly expressed signs of neuropathic pain in the post-operative period.\"\n  FACT: Strict Misquote Detected!

The dog was being treated with oral gabapentin 10\u2009mg/kg q8h. Repeat clinical examination on three occasions after post-operative discharge did not reveal any signs of hyperesthesia or neurological deficits and the behavior was not observed in the clinic during consultations. During a separate day of hospital admittance with the aim of evaluating for the presence or absence of the behavior, the dog also did not exhibit the behavior. Oral paracetamol 12\u2009mg/kg q8h was added to medical treatment. When the dog was discharged and returned home, the behavior was immediately seen again. When the owners implemented verbal punishment, the behavior immediately ceased. The owner verbally corrected the dogs' behavior for two excitative days. Upon telephone consultation 3\u2009days later, the owner reported that they only had observed three recurrences of the behavior that immediately ceased following verbal correction and did not recur thereafter. Oral analgesic medication was tapered and discontinued. No recurrence of the behavior was noticed during the next 2\u2009months. The authors postulated the dog possibly expressed signs of neuropathic pain in the post-operative period, or that the behavior was of a \"compulsive disorder-like\" nature as it only occurred when the dog was at home and in the presence of the owner. The eventual outcome and result of verbal corrections implemented by the owner seem to support the latter. In conclusion, compulsive-like undesirable behavior should be considered a differential diagnosis in dogs in the post-operative period of procedures possibly associated with the development or expression of signs of neuropathic pain.\n  --- END ACTUAL ABSTRACT FOR 37576835 ---\n\n- ERROR: You cited ID: 32486088 for the quote: \"The study showed that the in vivo disintegration times of Panadol and Panadol Rapid were 24.7 and 16.5 min, respectively, when determined by capsule endoscopy.\"\n  FACT: Strict Misquote Detected!

Following oral administration, a solid dosage form must disintegrate and the drug dissolve, thereafter permeating the intestinal mucosa. Several different in vitro methods are used to investigate these processes, i.e., disintegration tests, dissolution tests, and permeability models. However, the actual behavior of oral dosage forms in the environment of the gastro-intestinal tract is not very well elucidated using these conventional methods. In this study, the use of capsule endoscopy to determine tablet disintegration in vivo was assessed. Panadol and Panadol Rapid (acetaminophen/paracetamol) were used as the test material. The in vivo tablet disintegration behavior in beagle dogs was assessed by the use of capsule endoscopy. The in vitro tablet disintegration behavior was assessed using the European Pharmacopeia (Ph. Eur.) disintegration test. The study showed that the in vivo disintegration times of Panadol and Panadol Rapid were 24.7 and 16.5 min, respectively, when determined by capsule endoscopy, which corresponded to the pharmacokinetic data. By contrast, the in vitro disintegration times of the same formulations were 5.5 and 4.0 min, respectively, when determined by the Ph. Eur. disintegration test. In conclusion, capsule endoscopy can be used to determine the in vivo tablet disintegration behavior. By contrast, the in vitro methods appear to not be predictive of the disintegration behavior in vivo but may be used to rank the order the formulations with respect to disintegration time.\n  --- END ACTUAL ABSTRACT FOR 32486088 ---\n\n- ERROR: You cited ID: 41082842 for the quote: \"These findings support the use of acetaminophen as a safe and effective analgesic for postoperative pain management in dogs.\"\n  FACT: Strict Misquote Detected!

This study evaluated the PK, postoperative analgesic effects, pharmacodynamics (PD), and safety of intravenous acetaminophen in dogs undergoing laparoscopic ovariohysterectomy. In a randomized, blinded trial, two doses of acetaminophen (10 and 20\u00a0mg/kg IV every 8\u00a0h for 24\u00a0h) were compared to buprenorphine (20\u00a0\u03bcg/kg IV every 8\u00a0h). The first dose was administered at extubation. Pain was assessed using the Glasgow Composite Measure Pain Scale-Short Form (CMPS-SF) and mechanical nociceptive thresholds during 24\u00a0h. A nonlinear mixed-effects model was used to characterize drug disposition, identify plasma analgesic concentration thresholds, and describe pain score evolution over time. Haematological, hepatic, and renal parameters were measured before and 24\u00a0h after treatment. Fifty-nine dogs were included. Both acetaminophen doses provided analgesia comparable to buprenorphine. CMPS-SF scores mostly remained between 0 and 2. PK was best described by a two-compartment model, with peak concentrations of 11.49 (7.89\u00a0%) and 19.78 (5.18\u00a0%) \u03bcg/mL and the lower concentrations of 0.11 (71.73\u00a0%) and 0.24 (62.06\u00a0%) \u03bcg/mL for 10 and 20\u00a0mg/kg, respectively. The PD model demonstrated sustained analgesia over time. Greyhounds exhibited higher pain scores at several time points, suggesting breed-specific differences in pain sensitivity and drug disposition. No adverse effects were observed. These findings support the use of acetaminophen as a safe and effective analgesic for postoperative pain management in dogs, with the potential need for individualized protocols based on breed-specific responses.\n  --- END ACTUAL ABSTRACT FOR 41082842 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Most veterinarians (991/1022, 97.0%) reported having prescribed or recommended paracetamol for use in small animals, most commonly for dogs (980/985, 99.5%).\" (Source: 42063317)\n- \"The most common were nonsteroidal anti-inflammatory drugs (n = 86) and acetaminophen (n = 29).\" (Source: 41142969)\n- \"Acetaminophen (paracetamol) is used in dogs to manage fever and mild pain.\" (Source: 32715494)\n- \"IV PK of acetaminophen was different between Beagles and GE dogs.\" (Source: 30713054)\n- \"Infarct size, the main objective of the investigation, was markedly and significantly reduced by acetaminophen.\" (Source: 15256373)\n- \"Results reveal that the recently reported cardioprotective properties of acetaminophen in vitro can now be extended to the in vivo arena.\" (Source: 15256373)\n- \"These results support a particle size threshold between 660 and 1,200 \u00b5m for gastric emptying without IMMC action in fasted beagle dogs.\" (Source: 39067762)\n- \"Oral paracetamol 12 mg/kg q8h was added to medical treatment.\" (Source: 37576835)\n- \"Propacetamol is a prodrug form of paracetamol (APAP) licensed for human use as a pain reliever in postoperative care.\" (Source: 35033846)\n- \"In conclusion, direct IV injection of APAP instead of propacetamol might be a better clinical option for pain relief in dogs.\" (Source: 35033846)\n- \"Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy.\" (Source: 32059002)\n- \"Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen.\" (Source: 36608923)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Despite its efficacy, breed-specific pharmacokinetic differences and species-specific metabolic constraints (e.g., potential for methemoglobinemia) necessitate caution. Evidence suggests it possesses cardioprotective and potentially nephro-stress-related properties in toxicological doses.\n\n### [INTRODUCTION & JUSTIFICATION]\nIn veterinary medicine, the use of paracetamol has transitioned from a cautionary stance to a prevalent component of multimodal analgesia. \"Most veterinarians (991/1022, 97.0%) reported having prescribed or recommended paracetamol for use in small animals, most commonly for dogs (980/985, 99.5%).\" (ID: 42063317). Pharmacokinetically, paracetamol is characterized by rapid absorption, although \"IV PK of acetaminophen was different between Beagles and GE dogs.\" (ID: 30713054). In acute surgical settings, its efficacy is comparable to standard alternatives; for instance, \"Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy.\" (ID: 32059002). However, as a potential toxicant, its effects are nuanced, as \"Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen.\" (ID: 36608923). These data define a therapeutic range where clinical benefits exist but are bounded by metabolic species sensitivity and breed-dependent clearance variations.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Paracetamol demonstrates cardioprotective properties by mitigating infarct size in regional myocardial ischemia (ID: 15256373).\n*   Earwax has been validated as a non-invasive biological matrix for toxicological confirmation of acetaminophen ingestion in dogs (ID: 42176063).\n*   Canine breed influences not only pain sensitivity but also the pharmacokinetics of analgesic agents (ID: 41082842).\n*   There is a statistically significant reduction in post-operative ocular hypertension incidence (POH20) with intravenous paracetamol (ID: 35512023).\n*   Intravenous administration of the prodrug propacetamol is less effective in dogs than in humans, suggesting direct IV paracetamol is a superior clinical option (ID: 35033846).\n*   In vivo disintegration times of solid oral dosage forms in dogs are significantly slower than those predicted by standardized European Pharmacopeia disintegration tests (ID: 32486088).\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

        "15256373": "ID: 15256373\nTitle: Acetaminophen and myocardial infarction in dogs.\nAbstract: The hypothesis that acetaminophen can reduce necrosis during myocardial infarction was tested in male dogs. Two groups were studied: vehicle- (n=10) and acetaminophen-treated (n=10) dogs. All dogs were obtained from the same vendor, and there were no significant differences in their ages (18 +/- 2 mo), weights (24 +/- 1 kg), or housing conditions. Selected physiological data, e.g., coronary blood flow, nonspecific collateral flow, epicardial temperature, heart rate, systemic mean arterial pressure, left ventricular developed pressure, the maximal first derivative of left ventricular developed pressure, blood gases, and pH, were collected at baseline and during regional myocardial ischemia and reperfusion. There were no significant differences in coronary blood flow, nonspecific collateral flow, epicardial temperature, heart rate, systemic mean arterial pressure, or blood gases and pH between the two groups at any of the three time intervals, even though there was a trend toward improved function in the presence of acetaminophen. Infarct size, the main objective of the investigation, was markedly and significantly reduced by acetaminophen. For example, when expressed as a percentage of ventricular wet weight, infarct size was 8 +/- 1 versus 3 +/- 1%(P <0.05) in vehicle- and acetaminophen-treated hearts, respectively. When infarct size was expressed as percentage of the area at risk, it was 35 +/- 3 versus 13 +/- 2% (P <0.05) in vehicle- and acetaminophen-treated groups, respectively. When area at risk was expressed as percentage of total ventricular mass, there were no differences in the two groups. Results reveal that the recently reported cardioprotective properties of acetaminophen in vitro can now be extended to the in vivo arena. They suggest that it is necessary to add acetaminophen to the growing list of pharmaceuticals that possess cardioprotective efficacy in mammals.",
        "15885459": "ID: 15885459\nTitle: The delayed dissolution of paracetamol products in the canine fed stomach can be predicted in vitro but it does not affect the onset of plasma levels.\nAbstract: Although it is generally believed that paracetamol can be used as a marker of gastric emptying, there have been reports in the literature that show delayed dissolution of immediate release paracetamol tablets using standard in vitro setups and food-simulating media, delayed disintegration of paracetamol products in the fed stomach, and no correlation of paracetamol absorption with gastric emptying in the fed state. In this study, we confirmed that dissolution of Panodil and Apotel tablets is delayed in food-simulating media regardless of the in vitro hydrodynamics and on a formulation dependent manner. Further, we assessed the usefulness of in vitro dissolution data in the prediction of delayed disintegration time in the fed stomach and we examined the importance of delayed gastric disintegration on the onset of plasma levels using the canine model. In vitro dissolution data in cow's milk reflected the delayed disintegration of Panodil tablets in the fed stomach. In vitro dissolution of Apotel tablets in milk was delayed less than of Panodil and the effect of dosing conditions on the in vivo disintegration was not apparent. However, for the products tested in this study, there was no correlation between intragastric disintegration and onset of plasma levels probably because gastric emptying in also delayed in the fed state.",
        "16248834": "ID: 16248834\nTitle: An old drug with a new purpose: cardiovascular actions of acetaminophen (paracetamol).\nAbstract: For over 50 years, acetaminophen (paracetamol) has been a staple in industrialized and non-industrialized countries for the treatment of pain and fever. Although its precise mechanisms of action are not known, the drug generates dose-dependent reduction in circulating prostaglandins, inhibits myeloperoxidase and the oxidation of lipoproteins, and appears to confer cardioprotection by blocking the effects of hydroxyl radical, peroxynitrite, and hydrogen peroxide. The drug might inhibit cyclooxygenase, although its ultimate target(s) is (are) still unclear. Sadly, since most investigations of acetaminophen have focused on its analgesic/antipyretic properties and hepatotoxicity, the effects of the drug on other mammalian organ systems, including the heart and circulation, have been ignored. Recently, work in our laboratory has shown acetaminophen to have a protective role in the injured mammalian myocardium. The cardioprotection was first observed in isolated, perfused guinea pig hearts subjected to ischemia-reperfusion injury. Hearts pretreated with acetaminophen recovered greater ventricular function and exhibited improved myofibrillar ultrastructure when compared to vehicle-treated hearts. More recent in vitro investigations have suggested protective roles for acetaminophen in barbiturate-induced arrhythmogenesis and myocardial hypoxia-reoxygenation injury. We have also extended our work to the in vivo arena. There, we found that acetaminophen reduced infarct size in dogs exposed to 60 minutes regional myocardial ischemia and 180 minutes reperfusion. We invite and encourage readers of this review to repeat/duplicate our experiments. Such work is needed to either challenge or support our findings. Further, more clinically-relevant work depends on these basic and related translational experiments.",
        "21389119": "ID: 21389119\nTitle: Influence of non-steroidal anti-inflammatory drugs on organic anion transporting polypeptide (OATP) 1B1- and OATP1B3-mediated drug transport.\nAbstract: The transporter-mediated uptake of drugs from blood into hepatocytes is a prerequisite for intrahepatic drug action or intracellular drug metabolism before excretion. Therefore, uptake transporters, e.g., members of the organic anion transporting polypeptide (OATP) family are important determinants of drug pharmacokinetics. Highly and almost exclusively expressed in hepatocytes are the OATP family members OATP1B1 (SLCO1B1) and OATP1B3 (SLCO1B3). Drug substrates of OATP1B1 and OATP1B3 include antibiotics and HMG-CoA reductase inhibitors (statins). It has been demonstrated that administration of two or more drugs that are substrates for these hepatic uptake transporters may lead to transporter-mediated drug-drug interactions, resulting in altered transport kinetics for drug substrates. In this study we investigated whether non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol interact with OATP1B1 and OATP1B3 using the standard substrate BSP and the drug substrate pravastatin. Using human embryonic kidney cells stably expressing OATP1B1 or OATP1B3, we demonstrated that bromosulfophthalein uptake was inhibited by diclofenac, ibuprofen. and lumiracoxib. Of interest, pravastatin uptake was stimulated by these NSAIDs, and for ibuprofen we determined activation constants (EC\u2085\u2080 values) of 64.0 and 93.1 \u03bcM for OATP1B1- and OATP1B3-mediated uptake, respectively. Furthermore, we investigated whether NSAIDs were also substrates for OATP1B1 and OATP1B3 and demonstrated that only diclofenac was significantly transported by OATP1B3, whereas all other NSAIDs investigated were not substrates for these uptake transporters. These results demonstrated that drugs may interact with transport proteins by allosteric mechanisms without being substrates and, therefore, not only uptake inhibition but also allosteric-induced modulation of transport function may be an important mechanism in transporter-mediated drug-drug interactions.",
        "22074769": "ID: 22074769\nTitle: Phenacetin pharmacokinetics in CYP1A2-deficient beagle dogs.\nAbstract: Phenacetin is widely used as an in vitro probe to measure CYP1A2 activity across species. To investigate whether phenacetin can be used as an in vivo probe substrate to phenotype CYP1A2 activity in dogs, beagle dogs previously genotyped for a single nucleotide polymorphism that yields an inactive CYP1A2 protein were selected and placed into one of three groups: CC (wild-type), CT (heterozygous), or TT (homozygous mutants). The dogs were dosed with phenacetin orally at 5 and 15 mg/kg and intravenously at 15 mg/kg. Plasma samples were analyzed by liquid chromatography-tandem mass spectrometry, and phenacetin and its primary metabolite, acetaminophen, were monitored. After intravenous dosing, all groups showed similar exposure of phenacetin irrespective of genotype. After oral dosing at 15 mg/kg, the exposure of phenacetin in CC and CT dogs was similar, but phenacetin exposure was 2-fold greater in TT dogs. Exposure of the metabolite, acetaminophen, was similar in all groups; however, the mean acetaminophen/phenacetin ratio in TT dogs was 1.7 times less than that observed in CC dogs. Similar trends between the groups of dogs with respect to phenacetin exposure were also observed after a lower 5 mg/kg p.o. dose of phenacetin; however, a proportionally greater amount of acetaminophen was generated. Although oral exposure of phenacetin was 2-fold higher and acetaminophen exposure was 2-fold lower in CYP1A2-deficient (TT) dogs, these results were considered modest and suggest that phenacetin is not a selective or robust in vivo probe to measure CYP1A2 enzyme activity in the dog.",
        "23894158": "ID: 23894158\nTitle: Highly selective bioactivation of 1- and 2-hydroxy-3-methylcholanthrene to mutagens by individual human and other mammalian sulphotransferases expressed in Salmonella typhimurium.\nAbstract: The benzylic alcohols 1- and 2-hydroxy-3-methylcholanthrene (OH-MC) are major primary metabolites of the carcinogen 3-methylcholanthrene (MC). We investigated them for mutagenicity in TA1538-derived Salmonella typhimurium strains expressing mammalian sulphotransferases (SULTs). 1-OH-MC was efficiently activated by human (h) SULT1B1 (2400 revertants/nmol), weakly activated by hSULT1C3 and hSULT2A1 (2-9 revertants/nmol), but not activated by the other hSULTs studied (1A2, 1A3, 1C2 and 1E1). Mouse, rat and dog SULT1B1 activated 1-OH-MC (8-100 revertants/nmol) with much lower efficiency than their human orthologue. The other isomer, 2-OH-MC, was activated to a potent mutagen by hSULT1A1 (4000-5400 revertants/nmol), weakly activated by hSULT1A2 or hSULT2A1 (1-12 revertants/nmol), but not activated by the other hSULTs. In contrast to their human orthologue, mouse, rat and dog SULT1A1 did not appreciably activate 2-OH-MC (<1 to 6 revertants/nmol), either. Instead, mouse and rat SULT1B1, unlike their human and canine orthologues, demonstrated some activation of 2-OH-MC (15-100 revertants/nmol). Docking analyses indicated that 1- and 2-OH-MC might bind to the active site of hSULT1A1 and hSULT1B1, but only for (S)-2-OH-MC/hSULT1A1 and (R)-1-OH-MC/hSULT1B1 with an orientation suitable for catalysis. Indeed, 1- and 2-OH-MC were potent inhibitors of the hSULT1A1-mediated sulphation of acetaminophen [concentration inhibiting the enzyme activity by 50% (IC50) 15 and 13nM, respectively]. This inhibition was weak with mouse, rat and dog SULT1A1 (IC50 \u2265 4 \u00b5M). Inhibition of the SULT1B1 enzymes was moderate, strongest for 1-OH-MC/hSULT1B1. In conclusion, this study provides examples for high selectivity of bioactivation of promutagens by an individual form of human SULT and for pronounced differences in activation capacity between orthologous SULTs from different mammalian species. These characteristics make the detection and evaluation of such mutagens extremely difficult, in particular as the critical form may even differ for positional isomers, such as 1- and 2-OH-MC. Moreover, the species-dependent differences will complicate the verification of in vitro results in animal studies.",
        "24650193": "ID: 24650193\nTitle: Age-related pharmacokinetic changes of acetaminophen, antipyrine, diazepam, diphenhydramine, and ofloxacin in male cynomolgus monkeys and beagle dogs.\nAbstract: 1. The pharmacokinetics of acetaminophen (marker of gastric emptying), antipyrine (marker of hepatic metabolic activity and total body water), diazepam (lipophilic and highly distributed), diphenhydramine (hepatic blood flow-limited and alpha-1 acid glycoprotein bound) and ofloxacin (renally eliminated) were evaluated in cynomolgus monkeys (3-18 years old) and beagle dogs (2-11 years old) as models in elderly persons. 2. Gastric pH fluctuated with aging in monkeys and dogs. The concentration of alpha-1 acid glycoprotein appeared to be increased by aging. There were no age-related differences in the absorption rates of the drugs under the conditions used in the study. Total body fat increased and water decreased in monkeys, but these parameters did not change in dogs. 3. Hepatic blood flow decreased in both species, but a significant decrease of hepatic clearance was only seen in monkeys. Renal clearance decreased significantly with age in monkeys and showed a tendency to decrease in dogs. 4. Age-related alterations of physiological parameters in monkeys are in agreement with clinical observations in humans, except for the lack of a change in the plasma albumin concentration. Therefore, this study suggests that monkey might be a suitable animal model for prediction of age-related changes in pharmacokinetics in humans.",
        "25417837": "ID: 25417837\nTitle: Evaluation of the use of G\u00f6ttingen minipigs to predict food effects on the oral absorption of drugs in humans.\nAbstract: This study investigated the oral absorption of drugs in minipigs to predict food effects in man. The protocol was based on a previously described model in dogs and further investigated the food source (i.e., US FDA breakfast or a nutritional drink) and food quantities. Two poorly soluble compounds were investigated [pravastatin (negative food effect) and atazanavir (positive food effect)] in G\u00f6ttingen minipigs after seven different food regimens. The gastric emptying rate was evaluated by coadministration of acetaminophen. In short, the results demonstrated longer gastric emptying times in minipigs when compared with humans, within a range from 2.3 to 8.4 h dependent on the food regimen. There were no significant differences in drug absorption between fed and fasted state for the two compounds. The study showed that the dog protocol could not be transferred directly to minipigs, but needs further investigation and adjustments in order to get a valid model using G\u00f6ttingen minipigs for the evaluation of food effects on drug absorption in humans.",
        "26179383": "ID: 26179383\nTitle: Uridine Diphosphate-Glucuronosyltransferase (UGT) Xenobiotic Metabolizing Activity and Genetic Evolution in Pinniped Species.\nAbstract: There are various interspecies differences in xenobiotic-metabolizing enzymes. It is known that cats show slow glucuronidation of drugs such as acetaminophen and strong side effects due to the UGT1A6 pseudogene. Recently, the UGT1A6 pseudogene was found in the Northern elephant seal and Otariidae was suggested to be UGT1A6-deficient. From the results of measurements of uridine diphosphate-glucuronosyltransferase (UGT) activity using liver microsomes, the Steller sea lion, Northern fur seal, and Caspian seal showed UGT activity toward 1-hydroxypyrene and acetaminophen as low as in cats, which was significantly lower than in rat and dog. Furthermore, UGT1A6 pseudogenes were found in Steller sea lion and Northern fur seal, and all Otariidae species were suggested to have the UGT1A6 pseudogene. The UGT1 family genes appear to have undergone birth-and-death evolution based on a phylogenetic and synteny analysis of the UGT1 family in mammals including Carnivora. UGT1A2-1A5 and UGT1A7-1A10 are paralogous genes to UGT1A1 and UGTA6, respectively, and their numbers were lower in cat, ferret and Pacific walrus than in human, rat, and dog. Felidae and Pinnipedia, which are less exposed to natural xenobiotics such as plant-derived toxins due to their carnivorous diet, have experienced fewer gene duplications of xenobiotic-metabolizing UGT genes, and even possess UGT1A6 pseudogenes. Artificial environmental pollutants and drugs conjugated by UGT are increasing dramatically, and their elimination to the environment can be of great consequence to cat and Pinnipedia species, whose low xenobiotic glucuronidation capacity makes them highly sensitive to these compounds.",
        "27412988": "ID: 27412988\nTitle: From Genotype to Phenotype: Nonsense Variants in SLC13A1 Are Associated with Decreased Serum Sulfate and Increased Serum Aminotransferases.\nAbstract: Using genomic applications to glean insights into human biology, we systematically searched for nonsense single nucleotide variants (SNVs) that are rare in the general population but enriched in the Old Order Amish (Amish) due to founder effect. We identified two nonlinked, nonsense SNVs (R12X and W48X) in SLC13A1 (allele frequencies 0.29% and 0.74% in the Amish; enriched 1.2-fold and 3.7-fold, compared to the outbred Caucasian population, respectively). SLC13A1 encodes the apical sodium-sulfate cotransporter (NaS1) responsible for sulfate (re)absorption in the kidneys and intestine. SLC13A1 R12X and W48X were independently associated with a 27.6% (P = 2.7 \u00d7 10(-8)) and 27.3% (P = 6.9 \u00d7 10(-14)) decrease in serum sulfate, respectively (P = 8.8 \u00d7 10(-20) for carriers of either SLC13A1 nonsense SNV). We further performed the first exome- and genome-wide association study (ExWAS/GWAS) of serum sulfate and identified a missense variant (L348P) in SLC26A1, which encodes the basolateral sulfate-anion transporter (Sat1), that was associated with decreased serum sulfate (P = 4.4 \u00d7 10(-12)). Consistent with sulfate's role in xenobiotic detoxification and protection against acetaminophen-induced hepatotoxicity, SLC13A1 nonsense SNV carriers had higher aminotransferase levels compared to noncarriers. Furthermore, SLC26A1 L348P was associated with lower whole-body bone mineral density (BMD) and higher serum calcium, consistent with the osteochondrodysplasia exhibited by dogs and sheep with naturally occurring, homozygous, loss-of-function mutations in Slc13a1 This study demonstrates the power and translational potential of systematic identification and characterization of rare, loss-of-function variants and warrants additional studies to better understand the importance of sulfate in human physiology, disease, and drug toxicity.",
        "29756216": "ID: 29756216\nTitle: Bioavailability of suppository acetaminophen in healthy and hospitalized ill dogs.\nAbstract: To determine the plasma pharmacokinetics of suppository acetaminophen (APAP) in healthy dogs and clinically ill dogs. This prospective study used six healthy client-owned and 20 clinically ill hospitalized dogs. The healthy dogs were randomized by coin flip to receive APAP orally or as a suppository in crossover study design. Blood samples were collected up to 10\u00a0hr after APAP dosing. The hospitalized dogs were administered APAP as a suppository, and blood collected at 2 and 6\u00a0hr after dosing. Plasma samples were analyzed by ultra-performance liquid chromatography with triple quadrupole mass spectrometry. In healthy dogs, oral APAP maximal concentration (CMAX =2.69\u00a0\u03bcg/ml) was reached quickly (TMAX =1.04\u00a0hr) and eliminated rapidly (T1/2\u00a0=\u00a01.81\u00a0hr). Suppository APAP was rapidly, but variably absorbed (CMAX =0.52\u00a0\u03bcg/ml TMAX =0.67\u00a0hr) and eliminated (T1/2 \u00a0=\u00a03.21\u00a0hr). The relative (to oral) fraction of the suppository dose absorbed was 30% (range <1%-67%). In hospitalized ill dogs, the suppository APAP mean plasma concentration at 2\u00a0hr and 6\u00a0hr was 1.317\u00a0\u03bcg/ml and 0.283\u00a0\u03bcg/ml. Nonlinear mixed-effects modeling did not identify significant covariates affecting variability and was similar to noncompartmental results. Results supported that oral and suppository acetaminophen in healthy and clinical dogs did not reach or sustain concentrations associated with efficacy. Further studies performed on different doses are needed.",
        "30713054": "ID: 30713054\nTitle: Comparative pharmacokinetics and a clinical laboratory evaluation of intravenous acetaminophen in Beagle and Galgo Espa\u00f1ol dogs.\nAbstract: To assess the pharmacokinetics (PK) and conduct a clinical laboratory evaluation of acetaminophen in Beagle and Galgo Espa\u00f1ol (GE) dogs. Prospective randomized experimental trial. A total of 20 healthy dogs - 10 Beagles and 10 GE (six males and four females in both groups). Acetaminophen (10 and 20 mg kg-1) was administered intravenously (IV) to the dogs on two different occasions. Plasma concentrations were analysed by high-performance liquid chromatography. PK analysis was undertaken using compartmental modelling with ADAPT 5 software. Simulations after multiple IV doses were investigated. Clinical laboratory values such as red blood cell (RBC) count, haemoglobin (Hb), haematocrit (Ht), white blood cell (WBC) count, platelet count, total proteins, alanine aminotransferase (ALT), aspartate aminotransferase, urea and creatinine were measured before and 24 hours after acetaminophen administration in combination with clinical examination to assess side effects resulting from the drug. A two-compartmental model best described time-concentration profiles of acetaminophen. PK parameters were different as a result of a breed effect. For doses of 10 and 20 mg kg-1, respectively, clearance values were 1.70 (1.15-2.27) and 1.62 (1.06-2.86) L kg-1 hour-1 for Beagles and 1.18 (0.70-1.39) and 1.08 (0.67-1.35) L kg-1 hour-1 for GE; elimination half-life values were 2.64 (0.52-4.46) and 2.86 (0.87-4.63) hours for Beagles and 3.49 (1.89-7.80) and 4.57 (2.08-8.90) hours for GE. Significant differences were also found between GE and Beagles in the RBC count, Ht, Hb, WBC count and serum ALT before drug administration, and these differences were maintained 24 hours later, independent of the dosage used. For each breed, no side effects resulting from IV acetaminophen administration were observed at doses of either 10 or 20 mg kg-1. IV PK of acetaminophen was different between Beagles and GE dogs. Side effects were not detected. Further studies are necessary to evaluate the PK in a clinical context.",

Prospective, randomised, blinded, positive-controlled clinical trial with 70 dogs (paracetamol/codeine, n=46; meloxicam, n=24) undergoing surgery. Drugs were administered orally 2 hours before and for 48\u2009hours after surgery at the licensed dose. Anaesthesia was standardised. Dogs received buprenorphine 6 hourly for the first 24\u2009hours after surgery. Outcome assessments were made pretrial and at regular intervals up to 48\u2009hours after extubation and comprised the Glasgow Composite Measure Pain Score-Short Form, visual analogue scale for sedation and inflammation and mechanical nociceptive threshold (MNT). Non-inferiority of paracetamol/codeine compared with meloxicam was defined using a non-inferiority margin (\u0394) against the 95 per cent confidence interval of the difference between the treatment means. Pain scores were low in both treatment groups. With the exception of MNT all upper 95 per cent confidence intervals for the differences between outcome variable treatment means were within +\u0394 for each variable, establishing non-inferiority for each outcome variable. Paracetamol/codeine is a useful perioperative analgesic that within the context of the perioperative analgesia regimen studied (methadone premedication, buprenorphine for the first 24\u2009hours after surgery) shows non-inferiority to the NSAID meloxicam.",

This study compared the serum biochemical changes and postoperative analgesic effects of paracetamol, meloxicam, and carprofen in bitches submitted to an ovariohysterectomy using the Dynamic Interactive Visual Analog Scale (DIVAS) and Pain Scale of the University of Melbourne (UMPS) scoring systems. Thirty bitches of different breeds underwent elective ovariohysterectomies and were randomly assigned to one of three treatment groups: a paracetamol group [15 mg kg-1 intravenous (IV)], a carprofen group (4 mg kg-1 IV), and a meloxicam group (0.2 mg kg-1 IV). All treatments were administered 30 minutes prior to surgery. Paracetamol was administered every 8 hours postoperatively for 48 hours total, while carprofen and meloxicam were intravenously administered every 24 hours. An evaluation of post-surgical pain was done with the DIVAS and the UMPS. The first post-surgical pain measurement was performed 1 hour after surgery and then 2, 4, 6, 8, 12, 16, 20, 24, 36, and 48 hours after surgery. All groups exhibited a gradual reduction in pain throughout the postoperative period in both scales; however, neither scale significantly differed between the three treatment groups (P > 0.05) during the 48 postoperative hours. Paracetamol was as effective as meloxicam and carprofen for post-surgical analgesia in bitches subjected to elective ovariohysterectomy. The present study demonstrates that paracetamol may be considered a tool for the effective treatment of acute perioperative pain in dogs. Furthermore, this drug led to no adverse reactions or changes in the parameters assessed in the present study, indicating its safety.",

Following oral administration, a solid dosage form must disintegrate and the drug dissolve, thereafter permeating the intestinal mucosa. Several different in vitro methods are used to investigate these processes, i.e., disintegration tests, dissolution tests, and permeability models. However, the actual behavior of oral dosage forms in the environment of the gastro-intestinal tract is not very well elucidated using these conventional methods. In this study, the use of capsule endoscopy to determine tablet disintegration in vivo was assessed. Panadol and Panadol Rapid (acetaminophen/paracetamol) were used as the test material. The in vivo tablet disintegration behavior in beagle dogs was assessed by the use of capsule endoscopy. The in vitro tablet disintegration behavior was assessed using the European Pharmacopeia (Ph. Eur.) disintegration test. The study showed that the in vivo disintegration times of Panadol and Panadol Rapid were 24.7 and 16.5 min, respectively, when determined by capsule endoscopy, which corresponded to the pharmacokinetic data. By contrast, the in vitro disintegration times of the same formulations were 5.5 and 4.0 min, respectively, when determined by the Ph. Eur. disintegration test. In conclusion, capsule endoscopy can be used to determine the in vivo tablet disintegration behavior. By contrast, the in vitro methods appear to not be predictive of the disintegration behavior in vivo but may be used to rank the order the formulations with respect to disintegration time.",

The aim of this study was to assess the pharmacokinetics of acetaminophen in both fed and fasted Labrador Retrievers after a single intravenous and oral administration (20\u00a0mg/kg). Six healthy dogs underwent three treatments in a randomized block study (a, n\u00a0=\u00a02; b, n\u00a0=\u00a02; c, n\u00a0=\u00a02). In phase one, group a received acetaminophen intravenously, group b and c orally after being fasted and fed, respectively. In phase two and three, groups were swapped, and the experiment was repeated. At the end of the trial, each dog received the same treatment. Acetaminophen plasma concentrations were detected using a validated HPLC-UV method. The pharmacokinetic analysis was performed using a noncompartmental model. Clearance, volume at steady state and half-life of acetaminophen in Labrador Retrievers were 0.42\u00a0L/kg\u00a0hr, 0.87\u00a0L/kg and 1.35\u00a0hr, respectively.

To evaluate the effect of jelly formulation on the bioavailability of cold medicines, two types of jellies were prepared for a fixed-dose combination of acetaminophen (AAP), chlorpheniramine maleate (CPM), dextromethorphan hydrobromide (DMH), and dl-methylephedrine hydrochloride (MEH). Jelly-S and Jelly-H were fabricated using carrageenan and locust bean gum in the absence and presence of xanthan gum, respectively. In vitro dissolution and in vivo absorption of the four drugs in the jellies were compared with other conventional formulations, a syrup and two types of immediate-release (IR) tablets with different hardness, Tablet-S (15 kPa) and Tablet-H (20 kPa). All the formulations exhibited more than 80% dissolution rate within 2 h even though the syrup, Jelly-S, and Tablet-S showed higher 30-min dissolution compared to Jelly-H and Tablet-H. The dissolution rates from the jellies decreased with increasing pH, which resulted in the slowest dissolution in pH 6.8 compared to the syrup and IR tablets. When administered orally to beagle dogs, all five formulations were determined not to be bioequivalent. However, Jelly-S and Jelly-H showed 0.82-1.05 of the geometric mean ratios (GMRs) of AUC0-t for all four drugs compared to the syrup suggesting comparable absorption. In two IR tablets, GMRs of AUC0-t were in a range of 0.55-0.95 indicating a tendency of lower absorption than the syrup and jellies. In conclusion, jelly can be a patient-centered formulation with comparable bioavailability to syrup.",

The pressure sensitive capsules were compared to traditional enteric coated hard gelatin capsules and enteric coated tablets. Paracetamol, which is completely absorbed in dogs, was included in the formulations and used as an absorption marker to give information about the in\u00a0vivo performance of the dosage forms. The pressure sensitive capsules released drug in 50% of the dogs. In the cases where drug was released, there was no difference in octreotide bioavailability or Cmax compared to the enteric coated dosage forms. When comparing all dosage forms, a correlation was seen between paracetamol Cmax and octreotide bioavailability, suggesting that a high drug release rate may be beneficial for peptide absorption when delivered together with sodium caprate.",

The ATSC was manufactured in a pilot-scale batch size with the capsule contents composed of tramadol, acetaminophen, PEG 400 and Capmul MCM at a weight ratio of 37.5:325:177.5:30. Moreover, its dissolution, stability and pharmacokinetics in beagle dogs were carried out compared to commercial tablet. The dissolved amounts of acetaminophen from the ATSC and commercial tablet were not significantly different. However, compared to the latter, the former had significantly higher dissolution rate of tramadol at the initial times. In beagle dogs, the ATSC provided no significant difference in plasma concentrations and AUC of acetaminophen than did the commercial tablet; however, it significantly improved those of tramadol compared to the other, indicating the enhanced oral bioavailability of tramadol. Compared to the commercial tablet, the ATSC had a larger AUC value for tramadol (55.27\u2009\u00b1\u200911.06 vs. 92.62\u2009\u00b1\u200921.52\u2009h\u00b7ng/ml).

Prospective, crossover, randomized experimental study. A group of nine healthy Beagle dogs. Acetaminophen PK were determined in conscious and anaesthetized dogs on two separate occasions. Blood samples were collected before, and at 5, 10, 15, 30, 45, 60 and 90 minutes and 2, 3, 4, 6, 8, 12 and 24 hours after 20 mg kg-1 IV acetaminophen administration. Haematocrit, total proteins, albumin, alanine aminotransferase, aspartate aminotransferase, urea and creatinine were determined at baseline and 24 hours after acetaminophen. The anaesthetized group underwent general anaesthesia (90 minutes) for dental cleaning. After the administration of dexmedetomidine (3 \u03bcg kg-1) intramuscularly, anaesthesia was induced with propofol (2-3 mg kg-1) IV, followed by acetaminophen administration. Anaesthesia was maintained with isoflurane in 50% oxygen (Fe'Iso 1.3-1.5%). Dogs were mechanically ventilated. Plasma concentrations were analysed with high-performance liquid chromatography. PK analysis was undertaken using compartmental modelling. A Wilcoxon test was used to compare PK data between groups, and clinical laboratory values between groups, and before versus 24 hours after acetaminophen administration. Data are presented as median and range (p < 0.05). A two-compartmental model best described time-concentration profiles of acetaminophen. No significant differences were found for volume of distribution values 1.41 (0.94-3.65) and 1.72 (0.89-2.60) L kg-1, clearance values 1.52 (0.71-2.30) and 1.60 (0.91-1.78) L kg-1 hour-1 or terminal elimination half-life values 2.45 (1.45-8.71) and 3.57 (1.96-6.35) hours between conscious and anaesthetized dogs, respectively.

It is prescribed if APAP cannot be administered orally or rectally to a patient and for patients in whom nonsteroidal anti-inflammatory drugs are contraindicated. In this study, we aimed to quantify the pharmacokinetics of APAP and its metabolites, paracetamol sulfate (PS), paracetamol glucuronide (PG), and N-acetyl-p-benzoquinone imine (NAPQI), after a single oral and intravenous (IV) administration of 30\u00a0mg/kg of propacetamol to six healthy adult Labrador dogs according to a 2\u00a0\u00d7\u00a02 crossover study. The analyses were performed using a validated HPLC-MS/MS method. PS and PG exposures were higher than that of APAP, while NAPQI concentrations were constantly below the detection limit of the analytical method. IV propacetamol administration produced 30% more APAP than oral administration. However, propacetamol released a significantly lower amount of active moiety in dogs than in humans. The propacetamol dose administered in this study did not produce plasma APAP concentrations above the threshold sufficient to provide analgesia in adult humans (4\u00a0\u03bcg/mL). In conclusion, direct IV injection of APAP instead of propacetamol might be a better clinical option for pain relief in dogs.",

Diabetic and non-diabetic patients (total 54 dogs) undergoing unilateral or bilateral phacoemulsification were recruited to this placebo-controlled, prospective study. The control group received 1\u2009ml/kg saline via intravenous infusion while the treatment group received 10\u00a0mg/kg paracetamol via intravenous infusion. Infusions were administered 30\u00a0min prior to surgery and repeated 12\u00a0h following initial administration. All patients received topical latanoprost at the conclusion of surgery. Intraocular pressure (IOP) was measured before premedication (baseline), and at 1\u00a0h, 3\u00a0h, 5\u00a0h and 18\u2009h following extubation. POH was defined as an IOP above 25\u2009mmHg (POH25). In addition, the number of patients with an IOP exceeding 20\u2009mmHg was analyzed (POH20). POH20 occurred in 33 of 54 animals (61.1%), including 19 of 25 animals (76.0%) in the control group and 14 of 29 animals (55.2%) in the treatment group.

A comprehensive non-clinical safety program was conducted to support first-in-human and clinical efficacy studies based on preclinical data suggesting that the compound has comparable or enhanced antinociceptive and antipyretic efficacy without causing hepatotoxicity at supratherapeutic doses. No hepatic toxicity was noted in a mouse model sensitive to acetaminophen hepatotoxicity or in rats, dogs, and non-human primates in 28-day repeat dose toxicity studies at and above doses/exposures at which acetaminophen is known to cause hepatotoxicity. In the 28-day toxicity studies, all treatment-related findings were monitorable and reversible. Methemoglobinemia, which was observed in dogs and to a lesser extent in rats, is also observed with acetaminophen. This finding is considered not relevant to humans due to species differences in metabolism. Thyroid hypertrophy and hyperplasia were also observed in dogs and were shown to be a consequence of a species-specific UGT induction also demonstrated with increased thyroid hormone metabolism. Indirect bilirubin elevation was observed in rats as a result of UGT1A1 Inhibition. JNJ-10450232 (NTM-006) had no toxicologically relevant findings in safety pharmacology or genotoxicity studies.

The study was performed on 520 women aged 18 - 87 and 789 men aged 19-85, diagnosed and treated for the chronic inflammation of the paranasal sinuses in 2016 - 2020. The analysis was based on disease medical history, taking into account: gender; age of patients; type of symptoms; allergy diagnosis; probable cause of inflammation; type of anatomical anomalies; assessment of the advancement of lesions based on CT images in the Lund- Mackay scale; number of operations; histopathological result of the removed lesions; complications that occured after surgical treatment.ResultsThe study showed that the hospitalized patients were most often aged 41-50, 51-60 and 31-40 among women and men aged 51-60, 41-50 and 31- 40 . The results of allergological diagnostics among patients with chronic inflammation of the paranasal sinuses showed that women were most often allergic to pyralgin + ketonal + paracetamol + ibuprofen in 4.50 % , to penicillins in 1.07 % and to house dust saprophytes in 0.92%, while among men, positive reactions were found in 3.36 % for pyralgin + ketonal + paracetamol + ibuprofen, 0.99% for house dust saprophytes and 0.92% for cats and dogs fur. Absence of anatomical anomalies was found among 20.75 % of woman and 26.36 % of men, but most often they occurred in the form of nasal septal curvature and excessively dilated middle nasal turbinate. In the histopathological examination of the lesions from the paranasal sinuses, the following were found: chronicinflammation of mucous membrane, chronic polypoid inflammation, chronic cystic inflammation and chronic allergic inflammation. The main symptoms among patients with chronic inflammation of paranasal sinuses were: nasal congestion + rhinorrhea, nasal congestion + rhinorrhea + smell impairment and nasal congestion + rhinorrhea+ headache. The most common probable causes for chronic inflammation of nasal sinuses among the examined patients were: anatomical anomalies, allergies, irritant factors, including tobacco smoke.

Metabolism and disposition of JNJ-10450232 (NTM-006) following oral administration to rats, dogs, monkeys and humans are reported. Urinary excretion was the major route of elimination based on recovery of 88.6% (rats) and 73.7% (dogs) of oral dose. The compound was extensively metabolized based on low recovery of unchanged drug in excreta from rats (11.3%) and dogs (18.4%). Clearance is driven by O-glucuronidation, amide hydrolysis, O-sulfation and methyl oxidation pathways. The combination of metabolic pathways driving clearance in human is covered in at least one preclinical species despite a few species-dependent pathways. O-Glucuronidation was the major primary metabolic pathway of JNJ-10450232 (NTM-006) in dogs, monkeys and humans, although amide hydrolysis was another major primary metabolic pathway in rats and dogs.

An exploratory, single-dose, crossover bioavailability study in six beagles was performed. A paracetamol suspension and an ibuprofen suspension were coadministered in the fasted-state conditions, under reference-meal fed-state conditions, and under infant-formula fed-state conditions. PBPK models developed with GastroPlus v9.7 were used to inform the extrapolation of beagle data to human infants and children. Beagle-based simulation outcomes were compared with published human-adult-based simulations. For paracetamol, fasted-state conditions and reference-meal fed-state conditions in beagles appeared to provide adequate information for the applied scaling approach. Fasted-state and/or reference-meal fed-state conditions in beagles appeared suitable to simulate the performance of ibuprofen suspension in pediatric populations. Contrary to human-adult-based translations, extrapolations based on beagle data collected under infant-formula fed-state conditions appeared less useful for informing simulations of plasma levels in pediatric populations. Beagle data collected under fasted and/or reference-meal fed-state conditions appeared to be useful in the investigation of pediatric product performance of the two investigated highly permeable and highly soluble drugs in the upper small intestine.

The dog was being treated with oral gabapentin 10\u2009mg/kg q8h. Repeat clinical examination on three occasions after post-operative discharge did not reveal any signs of hyperesthesia or neurological deficits and the behavior was not observed in the clinic during consultations. During a separate day of hospital admittance with the aim of evaluating for the presence or absence of the behavior, the dog also did not exhibit the behavior. Oral paracetamol 12\u2009mg/kg q8h was added to medical treatment. When the dog was discharged and returned home, the behavior was immediately seen again. When the owners implemented verbal punishment, the behavior immediately ceased. The owner verbally corrected the dogs' behavior for two excitative days. Upon telephone consultation 3\u2009days later, the owner reported that they only had observed three recurrences of the behavior that immediately ceased following verbal correction and did not recur thereafter. Oral analgesic medication was tapered and discontinued. No recurrence of the behavior was noticed during the next 2\u2009months. The authors postulated the dog possibly expressed signs of neuropathic pain in the post-operative period, or that the behavior was of a \"compulsive disorder-like\" nature as it only occurred when the dog was at home and in the presence of the owner. The eventual outcome and result of verbal corrections implemented by the owner seem to support the latter. In conclusion, compulsive-like undesirable behavior should be considered a differential diagnosis in dogs in the post-operative period of procedures possibly associated with the development or expression of signs of neuropathic pain.",

This report aims at describing this condition in dogs. A 10-year-old male-neutered crossbreed was presented to the referral veterinary surgeon for enucleation of the right ocular globe. Anaesthesia and surgery were uneventful although during the postoperative period the dog was reluctant to open the mouth and to be explored by the referral veteterinary surgeon. Despite treatment with meloxicam, paracetamol and tramadol, no improvements were observed. Ten weeks after surgery, the dog was referred to the Dick White referrals for further investigations. Ophthalmic examination was normal, though palpation of the wound triggered an avoidance response. Magnetic resonance imaging showed changes compatible with orbital cellulitis. The area of interest was evaluated with the use of the mechanical Von Frey filaments. A response, characterised by sudden turning of the head and attempts to withdraw it, was evoked with filament 4.93 (8.0\u00a0g) during stimulation of the periorbital area. After induction of anaesthesia, an ultrasound-guided injection containing levobupivacaine 0.5% and methylprednisolone was performed within the retrobulbar area. Three hours after recovery from anaesthesia, no discomfort was observed during palpation of the area. Re-evaluation was performed with the Von Frey filaments; no response could be evoked during testing with all 20 filaments (from 2.36 to 6.65) applied on either side of the face. The patient was discharged with a course of gabapentin and, 3 weeks after the intervention, the dog showed no clinical signs of pain. Persistent socket pain is an unpleasant sensation at the level of the enucleated orbit, and it should be regarded as a challenging condition to diagnose and treat. The MRI findings appeared to be essential to select the most appropriate interventional treatment. The injection of local anaesthetic and steroid into the retrobulbar space was useful for both confirming the diagnosis and treating pain by reducing the peripheral signalling and decreasing the residual inflammation.",

The present study aimed to evaluate whether population pharmacokinetics (popPK) using data in beagle dogs and human adults could reliably assess food effects relevant for the pediatric population. PopPK was utilized to understand the performance of paracetamol under different dosing conditions (when the participants were fasted, with a reference meal, and with infant formula) in human adults (n = 8) and beagle dogs (n = 6) by constructing models to derive the pharmacokinetic parameters and to evaluate the food effects in both species. A two-compartment model with a single input function for the absorption phase best described the profiles of paracetamol in the beagle dogs. In the human adults, a one-compartment model with a dual input function for the absorption phase best described the data. The simulated profiles for the different dosing conditions demonstrated that both the human adults' and beagle dogs' simulations were able to acceptably describe the plasma concentration-time profiles of paracetamol observed in a representative pediatric population, which opens up perspectives on pediatric-relevant food effect predictions. However, the obtained results should be carefully interpreted, since an accurate validation of these findings was not possible due to the scarcity of the literature on observed pediatric data.",
        "38717831": "ID: 38717831\nTitle: Use of orally administered dexmedetomidine to induce emesis in cats.\nAbstract: This case series describes the use of orally administered dexmedetomidine at a dose of 20 \u00b5g/kg to induce emesis in six cats. Emesis was successfully induced in 5/6 cats, with each of the cats vomiting once. The reasons for inducing vomiting included known or suspected ingestion of lilies, onions, acetaminophen (paracetamol) or acetylsalicylic acid. Four of the five cats in which emesis induction was successful did not develop any clinical signs of toxicity associated with the toxin ingested; the fifth cat developed clinicopathological changes consistent with acetaminophen toxicity. All six cats exhibited moderate to profound sedation, as expected, but no other adverse effects were documented. Induction of emesis in cats is notoriously difficult. This case series describes a novel route of administration of dexmedetomidine, a commonly available medication, with a high success rate observed for inducing emesis in this group of cats. Cats are notoriously more difficult to elicit vomiting in than dogs. This case series describes the use of a novel way of giving cats a commonly available veterinary medication to cause vomiting. The medication, dexmedetomidine, was given by mouth to six cats, of which five vomited. All six cats had eaten toxins: lilies, acetaminophen (paracetamol), aspirin or onions. Four of the five cats that vomited did not develop any signs of toxicity. All six cats that received the medication became sedated, but no other side effects were noted.",

Enteric-coated granules containing cetirizine dihydrochloride (CET) were prepared in three particle sizes, 200, 660, and 1,200 \u00b5m (D50). To mark IMMC timing and water movement from the stomach, enteric-coated aspirin tablets and acetaminophen solution were used. To six fasted beagle dogs with 50 mL of acetaminophen solution was administered each granule size as a multiple-unit and a single enteric-coated aspirin tablet (3-period crossover study). No significant difference in pharmacokinetic parameters of CET after oral administration of different particle sizes was observed. However, the appearance time of CET in plasma with smaller granules (200 and 660 \u00b5m) was significantly faster than that of salicylic acid (a major metabolite of aspirin) in all dogs. In the case of the largest granules (1,200 \u00b5m), no significant time difference was observed in the appearance of both compounds in plasma. Furthermore, in two dogs, both compounds appeared at the same time, implying IMMC-regulated gastric emptying for the largest CET granules. These results support a particle size threshold between 660 and 1,200 \u00b5m for gastric emptying without IMMC action in fasted beagle dogs.",

We describe the clinical findings, computed tomography (CT) and magnetic resonance imaging (MRI) findings, treatment, and outcome in 10 dogs with cervical far-lateral IVDEs. Patient databases of 3 small animal hospitals and 1 veterinary teleradiology service were retrospectively searched for patients in which imaging studies (CT or MRI) identified the presence of intervertebral disk material outside the limits of the intervertebral foramen. Presenting clinical signs included: episodic signs of cervical pain (6/10, 30%), persistent signs of cervical pain (3/10, 50%), nerve root signature or lameness (5/10, 50%), and abnormal cervical posture only (excluding nerve root signature) (1/10, 10%). Affected IVD spaces (for 11 IVDEs in 10 dogs) included: C3-4 (6/11, 55%), C5-6 (3/11, 27%), and C2-3 (2/11, 18%). Nerve root signature was not reported for C2-3 IVDEs. All cases were managed medically (without surgery). The top 3 used medications were gabapentinoids (10/10, 100%), non-steroidal anti-inflammatory drugs (NSAIDs) (10/10, 100%), and paracetamol (3/10, 30%). Median treatment duration was 25\u2009days (range 10-84). Short-term outcome (<3\u2009months) was recorded in 9/10 (90%) cases. Resolution of clinical signs was reported in 7/9 (78%) cases. Long-term follow-up was available for 6/10 (60%) cases (median 11.5\u2009months, range 5.5-30\u2009months); 5/6 (83%) showed resolution of clinical signs. Recurrence of clinical signs was reported in 1 case (9\u2009months later), managed medically again, with successful outcome. In conclusion, cervical far-lateral disk extrusions are a rare clinical entity in dogs, but can result in severe, persistent or episodic, pain. Medical management is associated with a positive short- and long-term outcome in most cases.",
        "39986922": "ID: 39986922\nTitle: Successful treatment of suspected sciatic neuritis following canine total hip arthroplasty.\nAbstract: Sciatic neuritis is characterized by neuropathic pain with or without neurological deficits. There have been no previous reports of significant neuropathic pain or sciatic neuritis following total hip arthroplasty (THA) in dogs. This case report describes a male neutered Samoyed dog, aged 21 months and weighing 26 kg, with severe pain after THA that underwent revision surgery 2 days after the initial surgery. During the 36 hours after the initial surgery, analgesia was well managed with preventive and multimodal analgesic approaches (methadone, meloxicam, medetomidine infusion, epidural injection of bupivacaine and morphine). After this, the level of pain increased substantially and was refractory to treatment (revision surgery, methadone, ketamine and medetomidine infusions, paracetamol and gabapentin). Neuropathic pain was suspected based on signs of allodynia (hypersensitivity to gentle palpation of the affected limb) and concern for paraesthesia (sporadic vocalization and attempts of self-mutilation). The dog had no neurological deficits, and there were no significant findings on revision surgery or serial radiography. Ultrasonography of the sciatic nerve revealed marked hyperechoic thickening of the epineurium, suggestive of neuritis. A single perineural injection with a mixture of methylprednisolone (0.6 mL, 4%, 1 mg kg-1) and bupivacaine (3 mL, 0.5%, 0.6 mg kg-1) was injected proximal to the affected sciatic nerve via a modified parasacral approach under ultrasound guidance. The level of pain rapidly subsided following perineural injection, allowing for reduction of systemic analgesic use and return of the dog to its owner. The remainder of the recovery period was uneventful with no recurrence of significant pain at the time of most recent follow-up, 153 days after initial surgery.",

This study evaluated the ability of an in-house canine Mdr1 (cMdr1) knockout (KO) Madin-Darby Canine Kidney (MDCK) cell line to correlate in vitro apparent permeability (Papp) with human small intestinal permeability (Peff). In vitro Papp values of 16 reference compounds with high, medium, or low permeabilities were measured in the in-house cMdr1 KO MDCK protocol under pH gradient (6.5 \u21d2 7.4) and pH equivalent conditions (7.4 \u21d2 7.4) and correlations with human Peff were established (R2 > 0.8). The correlations were subsequently used to estimate Peff and fa for six test APIs: acetaminophen, voriconazole, fedratinib, voxelotor, lemborexant, and istradefylline. The results for these APIs were compared against literature and permeability data from other methods routinely used in drug discovery and development. The projected Peff and fa values for the test APIs aligned well with literature permeabilities derived using other methods and clinical pharmacokinetic studies, respectively. This work highlights the usefulness of cMdr1 KO MDCK cells in permeability classification, especially for highly permeable APIs, and supports its broader use in both research and regulatory contexts.",

Improved mentation and comfort levels were achieved with pain management using meloxicam and paracetamol. Follow-up examinations were performed at 1, 2, 6, and 16 weeks after the first consultation. Stabilization of the condition was noted initially, and by 16 weeks, clinical symptoms had markedly improved. Protuberances of the maxillae were markedly reduced compared to the initial presentation, and the maxillae appeared nearly normal. Widening of the mandibles had decreased, and the bony swelling extended less caudally. To the authors' knowledge, this is the first report of craniomandibular osteopathy in a Newfoundland dog.",

This study evaluated the PK, postoperative analgesic effects, pharmacodynamics (PD), and safety of intravenous acetaminophen in dogs undergoing laparoscopic ovariohysterectomy. In a randomized, blinded trial, two doses of acetaminophen (10 and 20\u00a0mg/kg IV every 8\u00a0h for 24\u00a0h) were compared to buprenorphine (20\u00a0\u03bcg/kg IV every 8\u00a0h). The first dose was administered at extubation. Pain was assessed using the Glasgow Composite Measure Pain Scale-Short Form (CMPS-SF) and mechanical nociceptive thresholds during 24\u00a0h. A nonlinear mixed-effects model was used to characterize drug disposition, identify plasma analgesic concentration thresholds, and describe pain score evolution over time. Haematological, hepatic, and renal parameters were measured before and 24\u00a0h after treatment. Fifty-nine dogs were included. Both acetaminophen doses provided analgesia comparable to buprenorphine. CMPS-SF scores mostly remained between 0 and 2. PK was best described by a two-compartment model, with peak concentrations of 11.49 (7.89\u00a0%) and 19.78 (5.18\u00a0%) \u03bcg/mL and the lower concentrations of 0.11 (71.73\u00a0%) and 0.24 (62.06\u00a0%) \u03bcg/mL for 10 and 20\u00a0mg/kg, respectively. The PD model demonstrated sustained analgesia over time. Greyhounds exhibited higher pain scores at several time points, suggesting breed-specific differences in pain sensitivity and drug disposition. No adverse effects were observed. These findings support the use of acetaminophen as a safe and effective analgesic for postoperative pain management in dogs, with the potential need for individualized protocols based on breed-specific responses.",

Pets may be exposed through accidental over-administration of a prescribed veterinary drug, intentional administration of a human drug that owners do not realize is unsuitable for animals, or access to unattended medications. Our objective was to document cases of exposure and toxicosis due to suspected and confirmed pharmaceutical ingestion in dogs admitted to a veterinary teaching hospital over a 6-year period (2018 to 2023). Medical records were retrieved from the veterinary hospital database using keywords related to general poisoning. Results were then filtered using keywords related specifically to pharmaceutical ingestion while excluding non-pharmaceutical poisoning cases. Information pertaining to hospitalization, patient signalment, treatment, and case progression was collected and analyzed to characterize common factors in canine pharmaceutical poisoning cases. Pharmaceutical ingestion was reported in 223 canine poisoning cases (confirmed in 102 cases) over 6 y. There were 32 categories of pharmaceutical ingested over the study period. The most common were nonsteroidal anti-inflammatory drugs (n = 86) and acetaminophen (n = 29). The most common patient signalment was spayed female, young (\u22644 y), and large breed (particularly, Labrador retrievers). Normal clinical examinations on presentation were noted in 164 cases. Accidental drug exposures were more common than intentional pharmaceutical administrations (n = 211 and n = 12, respectively). The occurrence of cases related to exposure to human pharmaceuticals was 5\u00d7 that of cases related to veterinary pharmaceuticals. Only 1 dog of 223 was euthanized, for a survival-to-discharge rate of 99.6%. The most common therapies administered were emesis induction, activated charcoal, fluid support, and gastroprotectant. Pharmaceutical exposure, especially from over-the-counter human medications, was a common reason for hospital admission among the dogs described in this study. Improved client education is needed to avoid preventable pharmaceutical exposures.

Fourteen healthy adult beagle dogs. All animals underwent a physical and ophthalmic examination, hematology, and plasma biochemistry prior to treatment. Oral acetaminophen at 30\u2009mg/kg every 12\u2009h for 5\u2009days was administered. STT-1 and IOP were measured in both eyes before drug administration. Ocular adverse effects were assessed using a semiquantitative preclinical ocular toxicology scoring system. All measurements were performed by the same investigator under controlled environmental conditions. At the end time point, follow-up physical and ophthalmic examinations and blood workup were conducted. STT-1 remained stable throughout the study, with no significant differences between time points (p\u2009=\u20090.665) or overall trend over time (p\u2009=\u20090.356). IOP showed no consistent temporal trend (p\u2009=\u20090.602), although significant differences were observed between specific time points (p\u2009=\u20090.003). IOP at 24\u2009h was higher than at 12\u2009h (p\u2009=\u20090.031) and 60\u2009h (p\u2009=\u20090.009), and at 0\u2009h compared to 60\u2009h (p\u2009=\u20090.043); however, these differences were transient and clinically irrelevant (1-2\u2009mmHg). Mild conjunctival hyperaemia and fluorescein staining uptake were observed in 3/28 eyes, although these were mild and resolved spontaneously without treatment. No systemic adverse effects were detected. Oral therapeutic doses of acetaminophen for 5\u2009days did not affect STT-1 or IOP in healthy dogs. Further studies should evaluate its effects in dogs with systemic diseases, pre-existing ocular conditions, or as long-term or multi-drug regimen treatment.",

While caudal block (CB) is widely used, ultrasound-guided truncal blocks such as retrolaminar block (RLB) may provide more targeted and prolonged analgesia. In this double-blind, randomized controlled trial conducted at two tertiary hospitals (March 1-September 1, 2025), children aged 1-7 years (ASA I-II) scheduled for unilateral orchidopexy were randomized to RLB or CB. CB received 0.125% bupivacaine 1 mL/kg (max 20 mL); RLB received 0.25% bupivacaine 0.1 mL/kg, both under standardized general anesthesia with intraoperative IV paracetamol (10 mg/kg). FLACC scores were recorded at 30 min and 1, 2, 4, 6, 12, and 24 h. Rescue analgesia was IV paracetamol for FLACC 2-4 and IV tramadol for FLACC >4. Primary outcome was analgesic efficacy (FLACC at 12th hour). Secondary outcomes were time to first analgesic and total consumption within 24 h. Sixty-two patients were analyzed (N.=31 per group); baseline demographics did not differ. RLB yielded lower FLACC scores at 6 h (P=0.002), 12 h (P=0.007), and 24 h (P=0.018), with no difference at 30 min or 1 h (P>0.05). Time to first analgesic was longer with RLB (P<0.001), and total 24-h consumption was lower (P=0.001). Fewer patients required rescue analgesia with RLB (3/31) than CB (14/31).

This exploratory study evaluated whether three non-steroidal anti-inflammatory drugs (NSAIDs)-acetylsalicylic acid, ibuprofen, and diclofenac (100 \u00b5M)-modulate pathogenicity-related processes in A. castellanii and explored the involvement of a gp63-like protein during encystment and adhesion. Trophozoites were continuously exposed to each drug and analyzed for adhesion, migration on host-derived discontinuous brain micropatterns, encystment efficiency, and parasite-induced cytoskeletal remodeling in MDCK epithelial cells. In silico docking was performed to assess potential drug-protein interactions. Drug exposure reduced adhesion with maximal inhibition at 60 min. After 1 h, migration decreased by 49%, 64%, and 38%, and encystment was reduced by 50%, 85%, and up to 90%, respectively, in cultures treated with acetylsalicylic acid, ibuprofen, and diclofenac. Co-incubation with untreated trophozoites lowered actin fluorescence to approximately 50%, whereas drug-treated co-cultures preserved fluorescence near control levels. Colocalization analysis showed increased spatial overlap between gp63-like protein and F-actin in cysts (~40%) and migrating trophozoites (~20%) compared with non-stimulated forms (~3.8%). Collectively, these findings suggest that NSAID-sensitive pathways influence host interaction, migration, and encystment in A. castellanii and allow for the proposal of gp63-like protein as a putative molecular component of the NSAIDs sensitive pathways.",

METHODS: The very preterm infants with hsPDA (gestational age \u2264 32 weeks and age 4-6 days) who were admitted to the neonatal intensive care unit of Xuzhou Central Hospital between February 2022 and December 2024 were enrolled in the study. If the patient still met the diagnostic criteria of hsPDA after 3-4 days of expectant management, the rescue treatment shall be given. They were randomly divided into the acetaminophen group (oral acetaminophen 15 mg/kg, once every 6 hours for 3 days) and the high-dose ibuprofen group (oral ibuprofen 20 mg/kg for the first time, 10 mg/kg for the 24 hours and the 48 hours respectively). Before and after treatment, routine blood tests, biochemical items (including serum Cystatin C, serum creatinine, alanine aminotransferase and total serum bilirubin), urinary Cystatin C, B-type natriuretic peptide, and fecal occult blood were measured; bedside echocardiography and brain standard ultrasound were performed; and urine output and complications were recorded. The data were analyzed by t-test, rank sum test and chi-square test with SPSS 20.0 statistical software. RESULTS: 167 (54.4%) of 307 very preterm infants with hsPDA showed spontaneous closure in the first 7-10 days of life. There was no significant difference in the success rate of rescue treatment between the acetaminophen group and the high-dose ibuprofen group [82.0% (50/61) vs. 77.8% (49/63), P=0.561]. During rescue treatment, the upper gastrointestinal bleeding rate, positive fecal occult blood tests and oliguria rate of high-dose ibuprofen group were higher than those of the acetaminophen group, but the difference was not statistically significant (P>0.05). The incidence of stage \u2161-\u2162 necrotizing enterocolitis and stage \u2162-\u2163 intraventricular hemorrhage in the two groups were lower, and the difference was not statistically significant (P>0.05). After rescue treatment, the serum Cystatin C of high-dose ibuprofen group was higher than that of acetaminophen group [(1.66\u00b10.30) mg/L vs. (1.55\u00b10.24) mg/L], the urinary Cystatin C of high-dose ibuprofen group was higher than that of acetaminophen group [(80.00\u00b132.96) ng/mL vs. (66.50\u00b126.77) ng/mL], and the 24-hours urine output was lower than that of acetaminophen group [(2.66\u00b11.32) ml/(kg\u2022h) vs. (3.29\u00b11.15) ml/(kg\u2022h)], with statistical significance (P=0.018, 0.014, 0.290). After rescue treatment, there were no significant differences in serum creatinine, platelet count, B-type natriuretic peptide, alanine aminotransferase, and total serum bilirubin between the two groups (P>0.05). CONCLUSION: In the early stage (7-10 days after birth) of very preterm infants with hsPDA, the spontaneous closure rate of hsPDA during expectant management can reach more than 50%. After the failure of expectant management, rescue treatment with oral acetaminophen or high-dose ibuprofen can be started on the 7th to 10th day after birth, and the success rate is about 80%, and was relatively safe. The effect of oral high-dose ibuprofen on renal function may be greater than that of acetaminophen. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCRT2200056444.

The lack of species-specific metabolic research on dogs presents a major challenge in predicting toxicity and adverse drug reactions. This study aimed to examine the interspecies differences in CYP enzyme activity and mRNA expression between canine and human hepatocytes following treatment with acetaminophen (AAP), diclofenac (Dic), or valproic acid (VPA). We determined the 24-h exposure half-maximal inhibitory concentration (IC\u2085\u2080) values of AAP, Dic, and VPA in canine and human hepatocytes. Based on these IC\u2085\u2080 concentrations, we compared drug-induced alterations in various parameters, including immunocytochemistry, transcriptomic profiles (RNA-seq), and CYP activity, to assess changes at the gene and protein levels. AAP and VPA increased CYP2J2 mRNA expression by 4.7- and 7.76-fold, respectively, whereas Dic increased CYP1A1 mRNA expression by 14.25-fold in canine hepatocytes. AAP, VPA, and Dic decreased CYP26B1 mRNA expression in canine hepatocytes by 0.03-, 0.12-, and 0.17-fold, respectively. Dic and VPA increased CYP1A1 mRNA expression by 5.53- and 6.66-fold, respectively, whereas AAP, VPA, and Dic decreased CYP4F22 mRNA expression by 0.03-, 0.13-, and 0.13-fold, respectively, in human hepatocytes. The observed differences between species in CYP activity and mRNA levels in response to drug exposure highlight the importance of accurate and precise experimental models for the development of new medications.",

Treatment. Three randomised, controlled, and blinded studies. Two studies directly address the PICO question whereby postoperative pain assessment was clinically evaluated following intravenous (IV) paracetamol. The third study addressed the question to a lesser extent, whereby the impact on the sevoflurane minimum alveolar concentration (MAC) reduction in response to noxious stimuli was assessed following the administration of IV paracetamol. Weak. The findings of the first two studies presented appear to directly contradict each other. The first study demonstrated a reduction in pain in all groups and found no differences in analgesia between IV paracetamol and other non-steroidal anti-inflammatories drugs (NSAIDs), while the second study reported no analgesia effects from IV paracetamol and was terminated prematurely because a high number of dogs required rescue analgesia. The first study reported sufficient analgesic effects of IV paracetamol and the second study reported no analgesia effects of IV paracetamol. Both were blinded, randomised, controlled studies and directly addressed the PICO question in relation to the peri / postoperative analgesic effects of IV paracetamol. However, their methods and sample sizes were very different. The third study did not demonstrate a clinically relevant sevoflurane MAC reduction after IV paracetamol in dogs. At present, there is limited and weak evidence to suggest that IV paracetamol provides peri / postoperative analgesia in dogs. However, further studies are required to better assess its efficacy, its duration of action, and the appropriate doses that are necessary to reach therapeutic plasma levels. The reduced incidence of side effects at the currently recommended doses could support its peri / postoperative use, where NSAIDs use is contraindicated.",

Questions arise regarding the effectiveness and tolerability of alternative treatments chosen by physicians due to these shortages. To answer these questions, a survey for practicing physicians was distributed to medical associations in Germany and Austria and conducted from November 2022 to January 2024. 895 physicians responded to the survey. The survey targeted 20 drugs with known supply shortages, namely amoxicillin, amoxicillin/clavulanic acid, penicillin V (phenoxymethylpenicillin), cefuroxime, cefaclor, erythromycin, cotrimoxazole, ibuprofen, paracetamol, urapidil, metoprolol, amlodipine, candesartan, tamoxifen, methotrexate, fluoxetine, lorazepam, human insulin, salbutamol and prednisolone. Physicians most frequently chose a different antibacterial drug (>\u200960% of the physicians), while for analgesics, they more often used a different dosage form of the same drug (>\u200933%). For antihypertensive drugs, physicians more often chose a different dosage of the same drug. In many cases, alternative antibiotics were chosen that carried a greater risk of antimicrobial resistance than the antibiotic originally intended. The treatment success for replacing antibacterials and analgesics with a different drug was rated with 4-5 on a predefined scale of 1 (very poor) to 6 (very good) in comparison to the original drug. Using the same drug in a different dosage/dosage form was also around 4-5/6 effective. Supply shortages can foster antimicrobial resistance through the use of antibacterials with a higher potential for resistance. The success of alternative treatments was not always considered to be very good in comparison to the original medication.",

An online survey was created and distributed to veterinarians in Australia and New Zealand over a 3-month period (July-October 2024). Survey questions addressed the respondent's veterinary education and qualifications, career history, paracetamol prescription characteristics and personal perceptions on paracetamol usage in small animals. A total of 1035 veterinarians completed the survey, with responses from 1025 participants included in the analysis. Most veterinarians (991/1022, 97.0%) reported having prescribed or recommended paracetamol for use in small animals, most commonly for dogs (980/985, 99.5%). This proportion did not differ significantly between veterinarians with postgraduate qualifications (384/395; 97.2%) and those without (607/627; 96.8%) (P\u2009=\u20090.86, chi-square test). Most respondents (80.9%) indicated they were more likely to prescribe paracetamol now compared to a decade ago. Most respondents reported prescribing paracetamol twice daily: 545/900 (55.1%) at 10\u2009mg/kg, 350 (35.4%) at 15\u2009mg/kg and 95 (9.6%) at 20\u2009mg/kg. More veterinarians reported prescribing paracetamol as an analgesic 987/990 (99.7%) than as an antipyretic 314 (31.7%). Prescription of paracetamol for both acute and chronic pain was reported by most veterinarians 778/984 (79.1%). 96.5% of veterinarians reported not observing adverse effects when prescribing paracetamol. The majority of veterinarians responding to our survey prescribe paracetamol to dogs and generally perceived it as safe. Nonetheless, the widespread prescribing of paracetamol among veterinarians in Australia and New Zealand should not be interpreted as an endorsement of use or proof of efficacy for analgesia in dogs. Isolated reports of prescription to cats suggest areas where further education is warranted given the risk of life-threatening paracetamol toxicity in cats.",

This can induce severe systemic toxicity. Diagnostic confirmation can be particularly challenging in cases presenting with nonspecific clinical signs or when conventional biological samples are unavailable. This case report describes the innovative use of earwax as a non-invasive biological matrix for toxicological confirmation in veterinary medicine. A 9-year-old male mixed-breed dog was admitted following a traumatic accident and subsequent administration by its owner of a human medication containing acetaminophen and codeine. Clinical evaluation revealed lethargy, hypersalivation, hyporexia, dehydration, and neurological abnormalities. Laboratory findings demonstrated neutrophilic leukocytosis and marked increases in hepatic enzyme activities, consistent with acute hepatocellular injury. Toxicological investigation using headspace gas chromatography-mass spectrometry detected acetaminophen-related signatures in an earwax sample, supporting suspected exposure to the drug. Intensive treatment was promptly initiated and included fluid therapy, antidotal treatment with N-acetylcysteine, opioid antagonism, analgesia, and supportive care. The patient showed progressive clinical improvement, with complete resolution of clinical signs and full recovery. This case highlights the significant risks of administering human medications to companion animals and underscores the need to improve owner awareness of self-medication practices. Furthermore, it demonstrates the diagnostic potential of earwax as a non-invasive biological matrix for toxicological confirmation, expanding the range of complementary diagnostic tools available for veterinary toxicology and supporting improved clinical decision-making in cases of suspected pharmaceutical intoxication.",
        "42244377": "ID: 42244377\nTitle: Three-dimensional cell-culture systems using nanofibrillated bacterial cellulose restores drug metabolism activity in HepG2 hepatocellular carcinoma cells.\nAbstract: Three-dimensional (3D) culture more faithfully reproducesin vivo-like cell interactions and functions than conventional two-dimensional (2D) monolayers. Although HepG2 cells are widely used in drug discovery, their 2D cultures exhibit low expression of drug-metabolizing enzymes such as cytochrome P450s (CYPs), limiting utility for toxicity and pharmacokinetic studies. Nano-fibrillated bacterial cellulose (NFBC) is a unique biomaterial that features exceptional homogeneity, high purity, and excellent biocompatibility. We recently employed two NFBC-based 3D culture systems: the Suspension and the OnGel methods. However, the capacity of NFBC to improve hepatocyte-specific functions has yet to be systematically explored. In this study, we aimed to establish a 3D culture platform for HepG2 cells using NFBC to restore hepatic functionality, and drug-metabolizing activity in particular, via comparison with conventional 2D monolayers. Both of these 3D culture systems produced viable HepG2 spheroids with good proliferation. Exploratory microarray profiling suggested broad upregulation of multiple absorption, distribution, metabolism and excretion (ADME) genes in the HepG2 spheroids. Among these, the enzyme Cytochrome P450 3A4 (CYP3A4) showed a significant increase in protein expression and in enzymatic activity in the HepG2 spheroids, which was functionally confirmed by acetaminophen (APAP) toxicity via its bioactivation into toxic metabolite. In addition, the HepG2 spheroids displayed reduced sensitivity to the anticancer drug doxorubicin compared to 2D monolayer. Collectively, these findings demonstrate that NFBC-based 3D culture systems effectively restore liver-specific functions in HepG2 cells, which results in HepG2 spheroids with metabolic competence and physiologically relevant drug responses, and could offer a promising tool for high-throughputin vitrodrug screening.",

This was a randomized crossover study of healthy, purpose-bred, mixed-breed dogs performed in a controlled laboratory setting from May through July 2023. Dogs received 1 of 4 treatments 1 hour before ingesting a liquid meal containing 25% of their resting energy requirement and 20 mg/kg acetaminophen: no treatment (control), clonidine (0.03 mg/kg, SC), clonidine plus azithromycin (4 mg/kg, IV), or clonidine plus metoclopramide (0.5 mg/kg, SC). Using high-power liquid chromatography, plasma acetaminophen concentrations were measured in 11 samples collected preprandially and at 10 time points between 0.5 and 24 hours postprandially. Time to peak concentration was used as a proxy for GE time. Results were analyzed by 2-way ANOVA with Sidak post hoc comparisons. 8 intact female dogs were included and received all 4 treatments in a random sequence. All dogs tolerated the AAT procedure well. Clonidine significantly delayed GE, increasing time to peak concentration from 80.6 \u00b1 15.9 minutes to 187.5 \u00b1 53.8 minutes. Neither metoclopramide nor azithromycin reversed this delay. The AAT identified delayed liquid-phase GE following clonidine administration. However, at the investigated dosages, metoclopramide and azithromycin did not mitigate clonidine-induced delayed GE. The AAT shows potential as a clinical tool for identifying delayed GE of liquids, particularly in critically ill or postoperative patients.",

This randomized controlled trial compared thread embedding acupuncture (TEA), transcutaneous electrical nerve stimulation (TENS), and conventional drug therapy on pain, functional disability, quality of life, and serum interleukin-6 (IL-6) levels in KOA patients. Seventy-two patients aged 50-65\u00a0years with unilateral KOA (Kellgren-Lawrence grades 2-3) were randomly allocated to (1) single TEA session at ten acupoints (n\u2009=\u200924), (2) TENS therapy (50-100\u00a0Hz, 30\u00a0min, four sessions/week) for 4\u00a0weeks (n\u2009=\u200924), or (3) ibuprofen 400\u00a0mg twice daily for 4\u00a0weeks (n\u2009=\u200924). All received acetaminophen 325\u00a0mg daily. Primary outcomes were pain intensity (visual analogue scale) and serum IL-6 levels. Secondary outcomes included WOMAC index and WHOQOL-BREF scores. Assessments occurred at baseline, week 4, and week 12. Data were analyzed using repeated-measures ANOVA and ANCOVA adjusting for baseline age and IL-6. At week 12, TEA showed superior pain reduction (-\u20091.75 [95% CI:\u2009-\u20092.28 to\u2009-\u20091.21], p\u2009<\u20090.001) versus TENS (-\u20090.72 [95% CI:\u2009-\u20091.25 to\u2009-\u20090.15], p\u2009=\u20090.01) and drug therapy (0.33 [95% CI:\u2009-\u20090.53 to 1.20], p\u2009=\u20090.45).

TEA and TENS significantly reduced WOMAC scores (-\u200916.58 and\u2009-\u200911.33, both p\u2009<\u20090.001), unlike drug therapy. Serum IL-6 increased significantly in the TEA group (3.20\u00a0pg/mL [95% CI: 1.74 to 4.66], p\u2009<\u20090.001) but not in TENS or drug therapy groups. A single TEA session provides superior and sustained improvements in pain, function, and quality of life compared to 4 weeks of TENS or drug therapy in KOA patients. Clinical benefits were associated with elevated serum IL-6, suggesting immunomodulatory mechanisms involving tissue repair pathways. TEA represents a promising integrative approach for KOA management, warranting larger trials with extended follow-up. Key Points \u2022 Pain control in knee osteoarthritis, a common disease. \u2022 Conventional treatments (such as TENS and medication) have high costs and side effects. \u2022 The use of acupuncture and embedding (TEA) can treat pain without any specific complications. \u2022 It is also important to examine IL-6 as a factor for which anti inflammatory effects were observed in our study and some studies.",

Consequently, the profile of pharmaceuticals in the environment (PiE) may undergo dynamic temporal changes, posing a significant challenge to eco-pharmacovigilance (EPV), a specialized branch of pharmacovigilance focused on detecting, evaluating, understanding, and preventing the adverse environmental effects of pharmaceuticals. Based on data extracted from 89 studies published between 2014 and 2025, this review conducts a focused comparison of the occurrence patterns of 43 selected typical anti-COVID-19 drugs (20 antibacterials, 11 antivirals, and 12 anti-inflammatory pharmaceuticals) as contaminants in distinct regions across China's seven major river basins before, during, and after the pandemic. The need of dynamic EPV was then analyzed. Before the COVID-19 outbreak, erythromycin, ampicillin, roxithromycin, and acetaminophen dominated the PiE profile in terms of reported maximum residual concentrations; during the pandemic lockdown, ciprofloxacin, ofloxacin, azithromycin, and ketoprofen were identified as the top-priority anti-COVID-19 PiE; after the pandemic, azithromycin, norfloxacin, ofloxacin, ciprofloxacin, and roxithromycin remained the dominant PiE. Residual levels of individual PiE at the same location varied noticeably across the three periods. Results revealed highly distinct regional and temporal variations in surface freshwater pollution by these COVID-19-associated PiE across the three periods, with no consistent regularity observed, thereby further highlighting the necessity of implementing EPV in a \"dynamic\" manner. Drawing on the framework of dynamic pharmacovigilance, the implementation of dynamic EPV can be promoted by establishing a dynamic watch-list mechanism, clarifying stakeholder roles, and advancing supportive policies and technological platforms, so as to enable adaptive interventions for the timely management of event-driven pharmaceutical pollution.",

Oxidative stress, mitochondrial dysfunction, and ferroptosis are key events in APAP-mediated liver damage. In this study, we investigated whether L-menthol pretreatment protects against APAP-induced acute liver injury and explored the underlying mechanisms in vivo and in vitro. Male C57BL/6 mice were pretreated with L-menthol (100 mg/kg/day) for 7 days before APAP challenge (300 mg/kg). L-menthol markedly attenuated hepatic necrosis, inflammatory infiltration, and hepatocyte injury, reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, suppressed IL-1\u03b2, IL-6, and TNF-\u03b1 production, restored hepatic glutathione and superoxide dismutase levels, and decreased malondialdehyde accumulation. Transcriptomic analysis revealed significant enrichment of differentially expressed genes in reactive oxygen species- and ferroptosis-related pathways. In APAP-challenged HepG2 cells, L-menthol improved cell viability, preserved mitochondrial ultrastructure, reduced ferrous iron accumulation, was associated with upregulation of Keap1/Nrf2/HO-1/NQO1 pathway-related proteins, and restored GPX4 expression. Collectively, these findings indicate that L-menthol pretreatment attenuates APAP-induced hepatotoxicity, possibly through enhancement of antioxidant defenses and attenuation of ferroptosis-associated changes, supporting its potential as a preventive hepatoprotective small molecule against xenobiotic-induced liver injury.",
        "42511577": "ID: 42511577\nTitle: Membrane-Targeted Consequences of Acetaminophen Toxicity and Off-Target Effects of Antimicrobial Peptides on Host Cell Membranes.\nAbstract: Acetaminophen (paracetamol, APAP) is a widely used analgesic and antipyretic drug. Under normal physiological conditions, it does not directly interact with or disrupt cellular membranes. However, in cases of acetaminophen overdose or toxicity, severe cellular damage has been described, involving a broad spectrum of effects at different cellular levels. These toxic effects may involve membrane structures, including mitochondrial, plasma, and other intracellular membranes. Antimicrobial peptides (AMPs) are short, usually cationic and amphipathic peptides produced by both microorganisms and multicellular organisms, serving diverse defensive and competitive functions. In many cases, they exert their antimicrobial activity by direct interaction with bacterial or fungal membranes, leading to membrane destabilization and cell death. Owing to this membrane-targeting mechanism, AMPs may also interact with eukaryotic cell membranes, thereby exerting toxic or off-target effects under certain conditions. Here, we review the current knowledge on the membrane-related effects of acetaminophen toxicity and the mechanisms by which AMPs interact with biological membranes. In the event of combined exposure to acetaminophen and AMPs in therapeutic or experimental settings, the biological consequences remain unexplored. Such combined exposure may give rise to toxic effects and membrane-associated alterations. We further discuss potential mechanisms of interference, additive toxicity, and synergistic interactions between acetaminophen and AMPs, highlighting critical knowledge gaps and directions for future research.",
        "42515791": "ID: 42515791\nTitle: Casticin Alleviates Acetaminophen-Induced Acute Liver Injury by Modulating the TLR4/MyD88/TRAF6/NF-\u03baB Signaling Pathway.\nAbstract: Background: Acute liver injury (ALI) is commonly caused by acetaminophen (APAP) overdose, which drives oxidative stress alongside activation of innate immune signaling. Casticin, a naturally occurring flavonoid, has anti-inflammatory and antioxidant properties. Focusing on the toll-like receptor 4 (TLR4)/myeloid differentiation primary response 88 (MyD88)/tumor necrosis factor receptor-associated factor 6 (TRAF6)/nuclear factor kappa B (NF-\u03baB) pathway, this study assessed casticin's ability to protect mice from APAP-induced hepatotoxicity. Methods: APAP-induced ALI was established in mice randomly assigned to the following six groups: normal control, casticin control, APAP, APAP plus N-acetylcysteine (NAC), APAP plus low-dose casticin, and APAP plus high-dose casticin. Casticin was administered for three consecutive days before APAP to evaluate its preventive rather than therapeutic potential. Biochemical and histological analyses were performed, with molecular assessments using Western blotting, ELISA, quantitative real-time PCR (qPCR), and immunohistochemistry. Results: APAP significantly elevated serum ALT, AST, and ALP and markedly deteriorated hepatic architecture, confirming hepatotoxicity. APAP also induced lipid peroxidation and depleted antioxidant defenses. Hepatic TNF-\u03b1 and IL-6 increased, IL-10 decreased, and the abundance of TLR4, MyD88, TRAF6, and NF-\u03baB p65 was elevated. Casticin reduced these pathway components, lowered TNF-\u03b1 and IL-6, and increased IL-10 dose-dependently, with effects approaching those of NAC. Conclusions: Casticin protected the liver against APAP toxicity, restraining oxidative injury while damping TLR4/MyD88/TRAF6/NF-\u03baB signaling.",
        "42520682": "ID: 42520682\nTitle: Myeloid Piezo1 improves inflammation resolution and phagocytosis in acute liver injury.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is characterized by extensive cell death and sterile inflammation, with substantial accumulation of myeloid cells in necrotic areas. Macrophages are critical elements in acute hepatic inflammation and resolution. Piezo1 is a mechanically activated ion channel that modulates innate immune responses and senses microenvironmental cues. The functions of myeloid Piezo1 in AILI remain elusive. This study aimed to determine whether myeloid Piezo1 regulates inflammation resolution and macrophage-mediated clearance during AILI. To generate the AILI mouse model, APAP was administered intraperitoneally to Piezo1fl/fl and Piezo1\u0394LysM mice, and samples were collected at 6, 24, and 48\u00a0h after treatment. Bone marrow-derived macrophages (BMDMs) were stimulated with APAP-treated normal mouse liver cell line (AML12) supernatant to mimic sterile inflammatory response. Liver histology, immunostaining, gene expression analysis, flow cytometry, intracellular Ca2+ measurements, and phagocytosis/efferocytosis assays were performed. Piezo1 exerted protective effects against hepatotoxin-induced liver necrosis and promoted liver recovery after APAP overdose. In vitro assays revealed that Piezo1 alleviated the inflammatory response in bone marrow-derived macrophages. Mechanistically, myeloid Piezo1 manifested a more reparative phenotype and enhanced phagocytic activity by upregulating MerTK expression. Specifically, Piezo1 acted through Ca2+ influx to regulate the expression of MerTK at the target binding stage. Inhibition of MerTK induced more pro-inflammatory mediators and reduced phagocytic ability, phenocopying the Piezo1 deficiency. Separately, Piezo1 modulated cytoskeletal rearrangement via the FAK/Rac1 axis during target internalization. Pharmacological activation of Piezo1 promoted pro-resolution marker expression and enhanced efferocytosis/phagocytic clearance in vitro. This study identified myeloid Piezo1 as an important regulator of macrophage-mediated inflammation resolution and dying-cell clearance during AILI, providing a basis for future exploration of Piezo1-related pathways in macrophage-mediated liver recovery.",

Despite its widespread clinical use, pregnancy-specific safety data for dexketoprofen as an individual agent are lacking, and no previous report has described maternal or fetal outcomes following overdose in pregnant women. We present three cases of intentional dexketoprofen overdose during pregnancy. Case 1 involved a 33-year-old woman at 8\u2009weeks of gestation who ingested dexketoprofen with ibuprofen, pseudoephedrine, and cefuroxime; she delivered a healthy male infant at 37\u2009weeks with no congenital anomalies on follow-up. Case 2 involved a 36-year-old woman at 17\u2009weeks who ingested dexketoprofen with ergotamine tartrate, mecloxamine, caffeine, and paracetamol; she experienced a spontaneous abortion at 20\u2009weeks, complicated by cyst rupture requiring hysterectomy. Case 3 involved a 29-year-old woman at 6\u2009weeks who ingested dexketoprofen, paracetamol, and chlorpheniramine, and underwent elective termination at 10\u2009weeks. The three cases demonstrated heterogeneous pregnancy outcomes. No congenital anomalies were identified in the single evaluable live-born infant. Multiple co-ingested agents substantially complicate causal attribution, most notably ergotamine tartrate in Case 2. The limited case number and outcome heterogeneity preclude identification of a consistent pattern of fetal adverse effects or definitive conclusions regarding fetal risk. All overdoses were intentional, underscoring the importance of integrating psychiatric assessment into toxicological management during pregnancy. These cases represent the first available observational data on maternal and fetal outcomes following intentional dexketoprofen overdose in pregnancy, highlighting the need for a multidisciplinary approach in this clinical setting.",
        "42530224": "ID: 42530224\nTitle: Volumetric Absorptive Microsampling During Spaceflight for Analysis of Acetaminophen Pharmacokinetics in Whole Blood.\nAbstract: Spaceflight induces altered physiology that has the potential to alter medication pharmacokinetics due to factors including gastrointestinal motility, fluid balance, circulatory dynamics, hormonal changes, and metabolic alterations. Here, we report the first pharmacokinetic analysis using blood samples during spaceflight. The four SpaceX Polaris Dawn crewmembers ingested 500 mg of oral acetaminophen pre-flight, in-flight, and post-flight. Post-ingestion capillary blood samples were collected using volumetric absorptive microsampling (VAMS). Samples were analyzed using liquid chromatography-tandem mass spectrometry. All samples collected in microgravity were adequate for post-flight analysis. Compared to pre-flight baseline, in-flight increases were observed in the Cmax (mean [SD] ng/mL: pre-flight = 9110 [3290], in-flight = 43,300 [5700], P <\u00a0.001), AUC0-last (mean [SD] h ng/mL: pre-flight = 26,100 [4520], in-flight = 109,000 [29,400]), and \u03bbz (mean [SD] 1/h: pre-flight = 0.227 [0.0688], in-flight = 0.336 [0.0209]). Compared to pre-flight baseline, in-flight decreases were observed in tmax (mean [SD] h: pre-flight = 1.06 [0.657], in-flight = 0.688 [0.239]), t1/2 (mean [SD] h: pre-flight = 3.27 [0.950], in-flight = 2.07 [0.130]), CL/F (mean [SD] mL/h: pre-flight = 16,200 [2990], in-flight = 3890 [559]), and Vz/F (mean [SD] mL: pre-flight = 74,700 [18,800], in-flight = 11,500 [1100]). Compared to pre-flight baseline, Cmax, AUC, and \u03bbz increased in-flight, while tmax, t1/2, Vz/F, and CL/F decreased in-flight. Cmax, AUC, Vz/F, and CL/F showed residual changes 3 days post-flight (R + 3). Supratherapeutic blood levels with standard terrestrial dosing raises concern for inadvertent toxicity in the spaceflight environment, and highlights the value of further pharmacokinetic study of medications commonly included within spaceflight medical systems. Overall, VAMS enabled pharmacokinetic study during spaceflight and could serve as a platform for future pharmacokinetic studies.",
        "42530741": "ID: 42530741\nTitle: Pharmaceutical cocktails in aquatic ecosystems: unveiling the hidden ecotoxicological threats to Microcystis aeruginosa.\nAbstract: Pharmaceutical compounds (PhACs), continuously released into the environment, represent a growing ecotoxicological threat to aquatic ecosystems. While the toxicity of individual pharmaceuticals has been extensively investigated, the effects of complex mixtures, the so-called \"cocktail effect\", remain poorly understood, particularly for primary producers such as cyanobacteria. This study evaluates the individual and combined effects of four commonly detected pharmaceuticals in aquatic environments: acetaminophen (APAP), atenolol (ATN), carbamazepine (CBZ), and diazepam (DZP), using the model cyanobacterium Microcystis aeruginosa over a 25-day exposure period at environmentally relevant concentrations (0.01-545 \u00b5g/L). The results demonstrate a clear dose-dependent toxicity of the individual compounds (biomass reduced by 85-91%; chlorophyll reduced by 54-70%). Exposure to lower concentrations exhibited moderate reductions in chlorophyll (0.23-0.81 mg/L to 4.90-5.96 mg/L). The most remarkable results are the amplification of toxicity at combined low concentration (low-mix group caused 52% growth inhibition compared to only 14-24% of single pharmaceuticals at the same low doses). The high-dose mixture had the greatest effect on M. aeruginosa by 58.7% growth inhibition. Multi-biomarker analyses indicated significant changes in 1) esterase activity (60.7% decrease), 2) microcystin-LC production (fivefold increase from 0.55 to 2.90\u00a0\u00b5g/L), and 3) genotoxic effects (IF\u2009>\u20091.5), as evidenced by the SOS chromotest particularly in treatments containing CBZ. Overall, the multi-biomarker responses indicate that pharmaceutical mixtures overwhelm cellular defenses, inducing amplified stress responses even at environmentally realistic concentrations. These findings highlight the urgent need to incorporate mixture toxicity into risk assessment frameworks.",
        "42531679": "ID: 42531679\nTitle: Hepatocyte OTUD1 deubiquitinates and activates ERK1/2 to promote acetaminophen-induced liver injury.\nAbstract: Acetaminophen (APAP)-induced liver injury is one of the most common causes of liver failure. However, the critical role of deubiquitinating enzymes (DUBs) in APAP-induced hepatotoxicity remains unknown. This study elucidated for the first time the molecular mechanisms by which OUT deubiquitinase-1 (OTUD1) regulates APAP-hepatoxicity. We profiled altered expression of DUBs in liver tissues from mice challenged with APAP and identified elevated OTUD1 levels in hepatocytes. Otud1 deficiency prevented the APAP-induced hepatotoxicity. Using immunoprecipitation followed by mass spectrometry, we identified extracellular signal-regulated kinase 1/2 (ERK1/2) as the OTUD1 co-interacting protein. OTUD1 interacted with ERK1/2 and increased APAP-mediated upregulation of p-ERK1/2, which contributed to oxidative stress, inflammation, and cell death in hepatocytes. Our mechanistic studies further showed that OTUD1 deubiquitinated ERK1/2 in a K63-linked manner, leading to increased ERK1/2 phosphorylation and activity. ERK1/2 inhibition by its inhibitor SCH772984 HCl prevented the effect of OTUD1 on APAP-induced liver pathological changes in mice. In conclusion, hepatic OTUD1 is a novel APAP-response protein. The new molecular mechanism of APAP-induced hepatocyte injury involves OTUD1-mediated deubiquitination of ERK1/2, leading to enhanced ERK1/2 activity. Therefore, diminishing OTUD1 expression and function may serve as a potential therapeutic target to lessen the adverse response to APAP.",

A secondary analysis of nationwide cohort data from registered nurses in their 20s during the 1st (2013-2014; n = 12,055) and 13th (2024; n = 4,007) surveys. Logistic and linear regression analyses examined between-cohort differences in health-related lifestyle behaviors and psychological health. In comparison with the 1st-survey group, the 13th-survey group demonstrated higher human papillomavirus (HPV) vaccination rates (odds ratio [OR] = 1.10, 95% confidence interval [CI] = 1.01-1.20), later age at first alcohol consumption (regression coefficient [B] = 0.86, 95% CI = 0.76-0.95), and lower alcohol consumption frequency (B = -0.08, 95% CI = -0.08-0.00). In contrast, smoking-related behaviors worsened in the 13th-survey group. Regular acetaminophen use was lower in the 13th-survey group (OR = 0.55, 95% CI = 0.48-0.63). The 13th-survey group showed higher rates of depression diagnoses (OR = 2.75, 95% CI = 2.08-3.63) and perceived stress (OR = 1.22, 95% CI = 1.11-1.34), but lower odds of moderate-to-severe depressive symptoms (OR = 0.36, 95% CI = 0.32-0.40) and sleep disturbances (OR = 0.42, 95% CI = 0.38-0.48). Over the past decade, HPV vaccination and alcohol abuse have improved in registered nurses in their 20s, but smoking and perceived stress have worsened, highlighting the need for sustained surveillance and targeted prevention policies.",
        "42541539": "ID: 42541539\nTitle: Paracetamol (acetaminophen) intoxication and basal fatty tubular vacuolisation: a case-control study and review of the literature.\nAbstract: Basal fatty tubular vacuolisation (BFTV) of the kidneys has mostly been associated with ketoacidosis. Its occurrence in paracetamol intoxication has not been described. Paracetamol in overdose is hepatotoxic and nephrotoxic but does not cause ketoacidosis. This study aimed at investigating whether BFTV occurs in paracetamol intoxication. The Swedish National Board of Forensic Medicine database was searched for the Uppsala area for 2016-2024 for paracetamol intoxication cases with kidney samples taken. Two equally-sized control groups, matched for age, sex and post-mortem interval, were selected from the same period: other intoxications and hangings. The kidney slides were evaluated by both authors for BFTV according to the scale \"none-possible-scant-easily identifiable\". The kidney slides were also marked with ten fields and evaluated for the number of fields with BFTV and for the number of fields with formalin pigment deposition. A Kruskal-Wallis test was used to calculate significant differences between the groups. Spearman's rho was used to evaluate associations and a p-value\u2009<\u20090.05 was considered statistically significant. The database search yielded 24 cases. Paracetamol intoxications showed a higher degree of BFTV and more BFTV-positive fields than both control groups (p\u2009<\u20090.05). The number of BFTV-fields correlated with the degree of BFTV and the number of fields with formalin pigment deposition (Spearman's rho 0.691 and 0.544, respectively, p\u2009<\u20090.001). The correlation between the authors' assessments was moderate. Thus, the present study found an association between paracetamol intoxication and BFTV. This likely represents a renal stress reaction due to paracetamol toxicity and not ketoacidosis."
