    Abstract Objective: The objective of this systematic review and meta-analysis was to assess the value of uric acid in predicting acute kidney injury caused by traumatic rhabdomyolysis.
    Methods: The search was conducted in MEDLINE, Scopus, Embase and Web of Science until November 1, 2023. Based on the inclusion and exclusion criteria, the articles were included by two independent researchers. Data regarding study design, patient characteristics, number of patients with and without AKI, mean and SD of uric acid and prognostic characteristics of uric acid were extracted from relevant studies. STATA version 17.0 was used to compute pooled measures of standardized mean differences, odds ratios, and diagnostic accuracy. I2 and chi-square tests were used to assess heterogeneity between studies.
    Results: We found 689 non-redundant studies, 44 of them were potentially relevant. Six articles met the inclusion criteria and were included in the review. The results of the meta-analysis confirmed that there was a significant correlation between serum uric acid levels and the occurrence of AKI (SMD = 1.61, 95% CI = 0.69 to 2.54, I2 = 96.94%; p value = 0.001). There were no significant publication biases.
    Conclusion: According to this meta-analysis, uric acid levels could be considered as a predictor of acute kidney injury following traumatic rhabdomyolysis.

    Abstract Introduction: A comprehensive analysis of the epidemiological features of aortic dissections in Azerbaijan Province, Iran, and their influence on patient survival remains unexplored. This study aimed to determine the incidence of aortic dissection and identify the associated factors of mortality in these patients.
    Methods: A retrospective longitudinal study was conducted using hospital records of patients diagnosed with aortic dissection in Tabriz, Iran, between 2017 and 2021. The 3-month mortality was followed up via telephone calls using the contact numbers provided in the patients' records. Then, independently associated factors of mortality were identified using a multivariate stepwise logistic regression analysis.
    Results: Among the 150 cases of aortic dissection identified, 74% (n = 111) were classified as type A, and 26% (n = 39) were classified as type B. The overall incidence proportion of aortic dissections was 2.35 per 100000 population. In type A dissections, 64% (71 out of 111) of patients received surgical treatment, while 21.6% (24 out of 111) received medical treatment. Among type B dissections, only 23.1% (9 out of 39) underwent surgery. The all-cause mortality rate at 3 months was 52.5% (73 out of 139 patients with complete follow-up), 47 male (54%) and 26 female (50%). Multivariate analysis showed that higher age was independently associated with increased mortality (odds ratio [OR] = 1.03; 95% confidence interval [CI]: 1.00-1.06, p = 0.027). In contrast, patients with DeBakey Type III classification (OR = 0.29; 95% CI: 0.01-0.87, p = 0.027), hypothyroidism (OR = 0.12; 95% CI: 0.01-0.99, p = 0.049), and those who received either surgical treatment (OR = 0.19; 95% CI: 0.05-0.76, p = 0.019) or medical treatment (OR = 0.18; 95% CI: 0.04-0.80, p = 0.024) had a lower chance of mortality. Gender was not found to be associated with the outcome.
    Conclusion: The study revealed an annual incidence rate of aortic dissection as 2.35 per 100000 population. Aortic dissection, regardless of type, remains a highly fatal condition, with over half of patients dying within 3 months of the initial event. To reduce the high mortality rates associated with aortic dissections, it is crucial to implement specific measures for the early identification of patients and ensure prompt and appropriate care.

    Abstract Introduction: In light of the potential of enhanced functional and neurological recovery in traumatic brain injury (TBI) with the administration of rapamycin, this systematic review and meta-analysis aimed to investigate the efficacy of rapamycin treatment in animal models of TBI.
    Methods: An extensive search was conducted in the electronic databases of Medline, Embase, Scopus, and Web of Science by July 1
    Results: Twelve articles were deemed eligible for inclusion in this meta-analysis. Pooled data analysis indicated notable reductions in the number of apoptotic cells (SMD
    Conclusion: Low to moderate-level evidence demonstrated a significant decrease in apoptotic and inflammatory markers and improved neurological status in rodents with TBI. However, no such improvements were observed in locomotion recovery.

    Abstract Introduction: Traumataic brain injury (TBI) represents a significant global health burden. This systematic review delves into the comparison of S100B and Neuron-Specific Enolase (NSE) regarding their diagnostic and prognostic accuracy in TBI within the adult population.
    Methods: Conducted on October 21, 2023, the search identified 24 studies encompassing 6454 adult patients. QUADAS-2 and QUAPAS tools were employed to assess the risk of bias. The analyses aimed to evaluate the diagnostic and prognostic performance of S100B and NSE based on sensitivity, specificity, and area under the curve (AUC). The outcomes were detecting intracranial injury, mortality, and unfavorable outcome.
    Results: Pooled data analysis tended towards favoring S100B for diagnostic and prognostic purposes. S100B exhibited a diagnostic AUC of 0.74 (95% confidence interval (CI): 0.70-0.78), sensitivity of 80% (95% CI: 63%-90%), and specificity of 59% (95% CI: 45%-72%), outperforming NSE with an AUC of 0.66 (95% CI: 0.61-0.70), sensitivity of 74% (95% CI: 53%-88%), and specificity of 46% (95% CI: 24%-69%). Notably, both biomarkers demonstrated enhanced diagnostic value when blood samples were collected within 12 hours post-injury. The analyses also revealed the excellent diagnostic ability of S100B with a sensitivity of 99% (95% CI: 4%-100%) and a specificity of 76% (95% CI: 51%-91%) in mild TBI patients (AUC = 0.89 [0.86-0.91]). In predicting mortality, S100B showed a sensitivity of 90% (95% CI: 65%-98%) and specificity of 61% (95% CI: 39%-79%), slightly surpassing NSE's performance with a sensitivity of 88% (95% CI: 76%-95%) and specificity of 56% (95% CI: 47%-65%). For predicting unfavorable outcomes, S100B exhibited a sensitivity of 83% (95% CI: 74%-90%) and specificity of 51% (95% CI: 30%-72%), while NSE had a sensitivity of 80% (95% CI: 64%-90%) and specificity of 59% (95% CI: 46%-71%).
    Conclusion: Although neither biomarker has shown promising diagnostic performance in detecting abnormal computed tomography (CT) findings, they have displayed acceptable outcome prediction capabilities, particularly with regard to mortality.

    Abstract Anal fistula refers to a clinical condition with local pain and inflammation associated with purulent discharge that affects the quality of life. Due to the lack of studies, the presence of bias, and high heterogeneity in the studies, the present systematic review is the first to be performed on the population-based database in this field. The present systematic review and meta-analysis was performed according to MOOSE guidelines. After systematic searching in electronic databases, only four articles met the inclusion criteria. After preparing a checklist and extracting data from the relevant articles, a meta-analysis was performed. All studies on the prevalence of anal fistula are related to Europe, and so far, no study has been conducted on other continents. The overall prevalence of anal fistula in European countries was 18.37 (95% CI: 18.20-18.55%) per 100,000 individuals, and the highest prevalence was reported for Italy (23.20 (95% CI: 22.82 to 23.59) per 100,000 people). From the present population-based (224,097,362) study results, it can be concluded that there is a prominent knowledge gap in this context. Because all the studies included in the current study relate only to Europe, the need for further research in this field in other countries is inevitably sensible.
