Data were extracted on animal species, sample size, induction methods, confirmation techniques, and reported advantages or disadvantages.Results: A total of 56 studies were included. Rats and mice were the most frequently used species. Induction methods comprised hormonal administration, genetic predisposition, chemical exposure (monosodium glutamate), ischemic injury, external stimulation, cell transplantation, xenotransplantation, and spontaneous development. A critical finding that emerged was that 60.7% of the studies failed to report confirmation of UL induction. Among the 22 studies that reported confirmation, caliper measurement was the most frequently used technique. This widespread lack of methodological rigor significantly undermines the credibility and reproducibility of many published models.Conclusion: This scoping review highlights not only the heterogeneity of UL animal models and the lack of standardized induction and evaluation protocols, but also identifies a critical gap in induction validation reporting that compromises the foundation of preclinical research in this field.","PeriodicalId":93850,"journal":{"name":"Acta cirurgica brasileira","volume":"41 ","pages":"e414426"},"PeriodicalIF":1.3,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13432877/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148686979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Central nervous system (CNS) inflammation has been linked to CC symptoms.

Blood and CSF were collected before anesthetic injection.Results: CSF vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP-1) levels were reduced in CC (p < 0.0001; p 0.00017) and CWC (p = 0.0269; p = 0.0421) compared to control.

Brazil's dual healthcare system reflects disparities in resource availability and clinical outcomes. This study compared epidemiological profiles of trauma patients treated at a public versus a private hospital in Salvador, Bahia, Brazil.Methods: We retrospectively analyzed 6,472 trauma-related hospitalizations from August 2021 to August 2023. Data were extracted from Hospital Information System/Department of Informatics of the Unified Health System and a private hospital database. Patients admitted under the 10th revision of the International Classification of Diseases, categories S00-T88, were included, excluding burns and orthopedic injuries. A χ2 test assessed associations between trauma mechanisms and hospitals.Results: Among the 6,472 cases, 6,342 occurred in the public hospital and 130 in the private hospital. In the public hospital, males accounted for 82.1% of the cases, and the leading causes were motorcycle crashes (21.7%) and gunshot wounds (16.2%). At the private hospital 58.4% of patients were males, with falls (50.8%) predominating among older adults. Violence-related injuries predominated in the public hospital, while falls predominated in the private hospital.Conclusion: This study revealed distinct trauma patterns in the public versus the private hospital in one Brazilian city. The public hospital treated younger male victims of violence, while the private hospital treated older patients with falls.

Entry points were mapped by dividing the muscle into four areas. Statistical analysis was performed using a Poisson marginal distribution and identity linkage function, followed by Bonferroni multiple comparisons. Statistical analysis included summary measures, group comparisons using Student and Mann-Whitney's tests, and Pearson and Spearman's correlations. Statistical significance was set at p < 0.05.Results: Quadrants I and II had significantly more DFN branches than quadrants III and IV (p < 0.001), whereas quadrants I versus II and areas III versus IV showed no significant differences (p < 0.05).Conclusion: Consistent with the clinical literature, the branches of the DFN in the TAM correspond to the described areas of the MTPs.
