Objectives: This study aimed to systematically review and quantify the association between D-dimer levels and injury outcomes in trauma patients through a meta-analysis.Methods: A systematic literature search of PubMed, MEDLINE/PubMed, and Web of Science was conducted from 2011 to 2023, supplemented by manual reference list searches. Two independent reviewers assessed the risk of bias using the Newcastle-Ottawa Scale. The primary outcomes were mortality and deep vein thrombosis (DVT).Results: Of 84 identified articles, 17 were eligible for full-text assessment, and 12 were included in the final analysis. A random-effects model was used to pool the study results. The analysis revealed a statistically significant difference in mean D-dimer levels between patients with poor outcomes and those without poor outcomes (p=0.0003). The standardized mean difference (SMD) was 0.51 (95% confidence interval [CI]:0.24 to 0.79). Furthermore, a significant difference in mean D-dimer levels was observed between survivors and non-survivors (p=0.03, SMD:0.42, 95% CI:0.04-0.79) and between patients with DVT and those without DVT (p=0.0008, SMD:0.79, 95% CI:0.32-1.25).Conclusion: This meta-analysis indicated that elevated D-dimer levels upon admission could be a valuable prognostic marker in trauma patients and might help predict poor outcomes.

Objectives: This study aimed to identify factors influencing helmet usage behavior among motorcyclists.
Methods: A cross-sectional study of injured motorcyclists was conducted at Shahid Rajaee Hospital (Shiraz, Iran), using the convenience sampling method. Data were collected via a structured medical form, and logistic regression with the “Backward” technique was applied to identify risk factors associated with helmet use.
Results: Among 147 patients, 139 (94.55%) were un-helmeted, and 8 (5.45%) were helmeted. The mean age of helmeted riders was 41.46±17.44 years, compared to 29.21±12.23 years for un-helmeted riders. After data balancing, key predictors of helmet use included riding before noon (OR=10.164, 95% CI [4.543, 22.738]), crashes in urban areas (OR=21.740, 95% CI [5.535, 85.383]), absence of head/neck injuries (OR=4.549, 95% CI [2.075, 9.970]), absence of facial injuries (OR=5.108, 95% CI [1.587, 8.694]).
Conclusion: These findings could assist policymakers in understanding helmet usage behavior and increasing helmet usage rates. They also support evidence-based strategies to reduce traffic crashes. Addressing helmet-related discomfort and enhancing public awareness of helmet benefits could significantly reduce motorcycle-related trauma.

Objective: According to the reports of the World Health Organization approximately 300,000 deaths occuryearly worldwide due to burns or burn-associated injuries. This study aims to review the epidemiology of burnsin pediatrics and adolescents in Fars province between 2017 and 2018.Methods: This is a cross-sectional study that investigated all people ≤18 years old who suffered from burninjuries in Fars province between 2017 and 2018. We use data from the file of burn patients which was providedby pre-hospital emergency services of Fars province. This data comprises demographic information (age andgender), burn-related information (type, degree, and severity of burns), mode of transfer (outpatient surgery ortransfer to hospital) and the outcome of the disease (death before arrival to the hospital or alive).Results: The average age of the subjects of this study was 5.8±8.9. We also categorized the subjects into fourage groups, 1-4, 5-8, 9-13 and 15-18 years. The number of boys who suffered from burn injuries is significantlymore than the girls (p=0.011). Also, there is a remarkable correlation between burn with age (p<0.001) andburn with disease outcome (p=0.01). The Most common cause of burns in boys was nonchemical hot objectsand liquids (28.5%). Likewise, the possibility of mortality in burn patients who faced an electric shock was22.66%. ([95%CI=2.32-220.63], p<0.001 OR=22.66).Conclusion: This study shows that pediatrics and adolescents ≤ 4 have the most burn injuries, and boys havetwice as many burn events as girls. More importantly, the most common cause of burns in both genders wasburning with non-chemical hot objects and liquids, in particular, in the age group of 1-4 years, in which eventhappens at home.

Objective: To evaluate the effect of COVID-19 pandemic on the incidence and mortality rate of road trafficinjuries in Shiraz, Iran.Methods: This cross-sectional study was performed on the data of patients who admitted by road trafficaccidents 18 months before the outbreak of COVID-19 and 18 months after COVID-19 in the largest providerof trauma level 1 care services in southern Iran. SPSS 19 software was used to analyze the data.Results: A significant decrease of 12.8% was observed in the number of patients admitted by road trafficaccidents during the COVID-19 pandemic period compared to the same period before the pandemic (p<0.0001).But the death toll from road traffic accidents has increased significantly during the COVID-19 pandemic periodcompared to the same period before the pandemic (p=0.01).Conclusion: Due to the COVID-19 restrictions, it seems that factors such as restrictions on suburban travel,closure of public and recreational spaces, reduction of intra-city traffic, people staying at home and a significantreduction in injuries caused by traffic accidents, is reasonable. On the other hand, these restrictions, quarantines,and COVID disease itself can lead to confusion, anxiety, fear of infection, and thus avoid or delay the searchfor health care and increase mortality. Therefore, planning and policy-making is essential in order to preparethe correct guidance for seeking treatment.
