Background: Pedestrian injuries killed almost 9000 Americans in 2021. Pedestrian fatality rates have increased annually since 2009. Many factors are associated with pedestrian fatalities, but one poorly-understood risk is the role of climate. We examined two primary sets of associations, those between pedestrian fatality crude rate (deaths per 100,000 population) and air temperatures in each US state (2012-2021) and those between national air temperatures and pedestrian fatality crude rate in each year from 2001-2021.

Methods: Data were obtained from public-facing CDC WISQARSTM and NOAA Climate-at-a-Glance websites. Descriptive and correlational analyses were conducted.

Results: Average air temperatures in individual US states correlated with pedestrian fatality crude rates in those states, r = 0.66. National average annual temperatures correlated with annual pedestrian fatality crude rates each year, r = 0.61. Secondary analyses considering correlations between annual pedestrian fatality crude rates and heating degree days, cooling degree days, and grid days over 70° F replicated primary results. Secondary analyses considering change in temperature from the previous year and pedestrian fatality crude rates were null.

Conclusions: US pedestrian fatality crude rates are associated with air temperatures. Causality cannot be assumed, but possible explanations for the association include increased exposure to traffic during daytime walking in cooler climates and increased exposure to risk through more walking at night in warmer climates. If findings were translated into NOAA-estimated climate change scenarios of 1° of temperature change over 30 years, correlational associations from the past two decades maintained unchanged, and population presumed stable, between 430-755 additional pedestrian fatalities could occur annually in the future.

Background: Fireworks are widely used worldwide for their visual and auditory appeal. However, they pose significant safety risks, particularly to children and young adults, many of whom sustain serious injuries from exposure to these pyrotechnic devices. Given the preventable nature of such incidents and their associated challenges, this study aims to examine the epidemiological impact of injuries caused by fireworks during the Chaharshanbeh Soori ceremony in Fars Province.

Methods: This cross-sectional study included all individuals who experienced injuries between March 6, 2022, and April 4, 2022. Data were collected by emergency technicians affiliated with Shiraz University of Medical Sciences. Statistical analyses included descriptive statistics (mean ± standard deviation [SD] and frequency [%]) and analytical methods, specifically the chi-square test.

Results: A total of 79 individuals were injured, with a mean age of 19.4 ± 11.5 years. The majority of the injured were male (73, 92.4%). Most injuries (66, 83.5%) occurred unintentionally, and 9 patients (11.4%) reported headache as a symptom, while 7 patients (8.9%) experienced visual disorders. Among those who received treatment, eye injuries were the most common (17, 26.2%). A significant difference was observed in recovery based on the injured body part; hand injuries had the highest recovery rate (6, 42.9%), compared to other injuries (p less than 0.029).

Conclusions: The findings indicate that fireworks-related accidents during the Chaharshanbeh Soori ceremony predominantly affect teenagers and young adults, often occurring unintentionally. Given the significant physical, financial, and long-term consequences of these injuries, this study's results can inform policymakers in implementing preventive measures. Additionally, it highlights the need to raise awareness among the public and relevant authorities to ensure safer conduct of such ceremonies in the future.

Background: Soccer is known to be a sport that carries a high risk of injuries due to its physical nature, involving intense contact and rapid movements like acceleration, deceleration, jumping, and sudden changes in direction. Compared to other sports, soccer is considered a contact sport with a heightened injury risk. The primary objective of this study was to assess the prevalence of sports injuries among professional soccer players.

Methods: In this cross-sectional study, 56 male professional footballers participated to assess their injuries. The Pre-Competition Medical Assessment (PCMA) was utilized as the standard protocol for evaluating the athletes. The study examined variables such as injury type, player position on the field, and body mass index (BMI) in accordance with the FIFA-recommended PCMA guidelines. Student t-test was used to compare demographic characteristics injured and healthy athlete. Chi square and fisher exact tests were used to assess the association between player position, injury type and BMI classification.

Results: In this study, the mean age of the soccer players was 19.38 ± 1.30 years, with a history of participating in 3 to 60 matches. The highest incidence of injuries was recorded in the knee (48.21%) and ankle (30.36%), respectively. A significant relationship was found between the players' positions on the field and knee pain, with strikers experiencing more knee pain compared to players in other positions (p less than 0.04). However, no significant association was observed between the players' BMI and the occurrence of sports injuries (p greater than 0.05).

Conclusions: Given the widespread occurrence of knee injuries among footballers, particularly in attacking players, proper planning and appropriate training protocols would be useful to prevent knee injuries and reduce treatment costs.

Background: International sports events like the Football World Cup affect the collective emotions of the global community. Usually, major sports events like the Football World Cup show beneficial effects on the community. However, many unwanted consequences such as accidents, premature deaths and violent supporter rivalries have been noticed during it. We aimed to report preventable premature deaths and clashes induced by rivalry among fans during the FIFA World Cup 2022 in Bangladesh.

Methods: We monitored local newspaper reports for data collection during the World Cup 2022 event and collected data for age, sex, the possible cause of death, and precipitating events related to the event.

Results: We found 23 World Cup Football-related deaths, 35 hospitalizations, and 45 injuries related to clashes between the rival fans of Argentina and Brazil. The median age of deceased was 20 years. The majority of the deaths happened in young males due to fall while hoisting flags. Deaths in the late age happened due to sudden emotional upsurge during the game day. And, clashes between rival fans mostly happened due to social bullying favoring and disfavoring a team.

Conclusions: This report indicates an important area of potentially preventable death related to World Cup Football and warrants public health attention even in a non-participating country, both locally and internationally.

Background: Epidural hematoma (EDH) is a type of intracranial hematoma commonly observed in trauma patients. This research aims to evaluate the factors contributing to the expansion of traumatic epidural hematoma (EDH).

Methods: This retrospective cohort study examined traumatic patients with EDH admitted to Taleqani Hospital, a prominent Western Trauma Center in Iran, from 2018 to 2023. Patients underwent an initial CT scan, and non-surgical patients received a delayed CT scan approximately 5 hours after the initial scan. Data analysis was performed using SPSS version 25 software.

Results: The study included 274 brain trauma patients with epidural hematoma. Among these patients, 142 (51.8%) did not undergo surgery, and 121 (85.2%) of the non-surgical patients were male. Motor vehicle accidents (MVAs) were the primary cause of EDH in 127 (46.4%) patients. The mean (±standard deviation) initial hematoma size was 8.86 (±9.71), and the mean (±standard deviation) delayed CT scan size was 8.12 (±8.10). In crude linear regression Two variables, namely Hematoma volume in the initial CT scan (P less than 0.001) and Mixed Density (P=0.007), were found to significantly impact the increase in hematoma size in delayed CT scans of non-surgical patients. But in the adjusted linear regression model, only the Hematoma volume in primary CT scan, was significant (P less 0.001). The R Square values were 0.72.

Conclusions: The identification of key variables influencing hematoma volume in delayed CT scans has the potential to guide more effective interventions, thereby improving patient outcomes and reducing trauma-related mortality.

Background: Helmet use has been introduced as one of the most highlighted strategies for preventing death and injury in motorcyclists. On the other hand, the cost of the helmet was introduced as a barrier to use. This study aimed at estimating the willingness to pay (WTP) of motorcyclists in Saqqez to buy and use safety helmets through the contingent valuation method (CVM).

Methods: This cross-sectional study was conducted in 2021 in Saqqez County, Kurdistan Province, Iran. Sampling was performed by two-stage clustering through probability proportion to the size. The sample size was 570. A preliminary questionnaire was designed and administered for validity and reliability approval. Data analysis was carried out through linear regression models using STATA 15.

Results: In total, 510 questionnaires were analyzed. The motorcyclists' mean age was 31.37 years (SD = 8.48). Only 251 individuals (49.22%) had an appropriate license, and approximately 40% declared that they never used a safety helmet. The mean WTP was estimated to be 3900000 Rials (15/6 US$) through CVM. Motorcyclist age, helmet use by the motorcyclist friends, and socio-economic status were found to be significantly correlated with their WTP.

Conclusions: The effect of socio-economic status on motorcyclist WTP highlights the significance of adopting supportive policies in this regard, along with stakeholder participation from the private sector and insurance companies. Moreover, the positive effect of helmet use by friends on individuals' WTP shows that improving the general culture of traffic safety can be accompanied by promising results, especially for motorcyclists.

Background: Mass shootings represent a persistent public health crisis. Prior studies have linked social determinants of health (SDOH) to the phenomenon of gun violence, but there remain limited analyses on mass shooting events specifically.

Methods: Mass shooting events from 2014-2019 were recorded from the Gun Violence Archive. State-level data regarding population, ATF registered weapons, federal firearm licensees and several SDOHs (poverty, unemployment and educational attainment) were collected from publicly-available US governmental databases. Giffords Law Center rankings were used to assess the relative strictness of each state's gun laws. Gun ownership rates were obtained from the RAND Corporation. Bivariate analyses compared each SDOH, as well as ATF registered weapons, Giffords Center ranking and gun ownership rates, to the death rate, injury rate, and combined injury/death rate from mass shootings in each state. All associations were evaluated via Pearson's Rho. Slope and p-values were analyzed, with a threshold significance value of p less than 0.05.

Results: Unadjusted analysis revealed poor mental health, decreased educational attainment and increased unemployment to all be associated with an increased risk of mass shooting-related injury or death. Adjusted analysis revealed fewer firearm regulations, higher gun ownership, lack of handgun magazine restrictions and lack of long-gun registration requirements were associated with an increased risk of mass-shooting death. Similarly, adjusted analysis revealed lack of handgun permit requirements to be associated with both an increased risk of mass shooting-related injury and combined risk of injury/death.

Conclusions: This study revealed associations between multiple SDOH and firearm restrictions with morbidity due to mass shooting events.

Background: Every year over 200,000 motorcyclists are killed globally. One poorly understood risk factor for motorcycle crashes is the role of motorcyclists' ability to hear traffic and other sounds around them in all directions. Most motorcycle helmets protect the head and permit vision in the forward direction, but they impair the wearer's ability to hear. This study evaluated user perceptions of Protective Helmet with Earpieces Equipped, a novel system that affixes technology onto existing motorcycle helmets to allow motorcyclists to better hear the surrounding environment in all directions.

Methods: 59 Colombian traffic police agents who rode motorcycles daily completed self-report surveys about their traditional motorcycle helmet, used a Protective Helmet with Earpieces Equipped helmet for two months, and then completed a follow-up survey. We tested two hypotheses: (a) at follow-up compared to baseline, motorcyclists would report decreases in perceived safety, comfort, and ability to detect sounds with their traditional helmet, as well as increased fatigue and stress from motorcycling with their traditional helmet, and (b) at follow-up, motorcyclists would report high perceived safety and perceived importance of hearing traffic sounds in all directions while motorcycling. Wilcoxon signed-rank test evaluated hypotheses.

Results: Participants rated perceived safety while using their traditional helmet to be significantly lower after using the Protective Helmet with Earpieces Equipped compared to before using it (Z=-3.5, p less than .001). There were no changes in other variables assessed. Following use of the new helmet, participants reported greatly improved safety (M=4.56, SD=0.54, where 4=safer and 5=substantially safer) and perceived the importance of hearing traffic sounds in all directions as high.

Conclusions: Improved auditory perception could increase motorcyclist safety. Participating traffic agents felt the Protective Helmet with the Earpieces Equipped greatly improved their ability to hear and improved their motorcycling safety. Perceived safety while using their traditional helmet decreased following use of the alternative.

Background: Suicide is one of the most common causes of juvenile death. Screening suicide risk is quite challenging and even more difficult in subjects who have no psychiatric disorder or other suicide risk factors in their medical history. To date, the association of serum lipid profile and suicidal risk has been evaluated in patients with different psychiatric disorders, yielding conflicting results. Here, we aimed to investigate the lipid panel and neutrophil-to-lymphocyte ratio in the sera of people with a first episode of suicide attempt in western Iran.

Methods: A total of 159 suicide attempters and 186 volunteers without history of suicide, aged 18-35 years, were evaluated in this experiment. Blood samples were collected between 8-10 AM and kept at 37 °C for blood clotting. We then analyzed the concentration of various lipid markers, including triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), using a series of enzymatic reactions. Additionally, we determined the neutrophil-to-lymphocyte ratio (NLR) by dividing the total number of neutrophils by the total number of lymphocytes after conducting peripheral blood cell counts.

Results: The concentration of TG was 94.2±5.8 mg/dL in males and 92.3±5.3 mg/dL in females. TC was 136.3±3.6 mg/dL in males and 152.7±4.4 in females, with a significant decrease in comparison with the control subjects (p less than 0.0001). NLR was 4.34±0.9 with a significant increase compared with the controls (P less than 0.002). (TG), (TC) and (LDL) levels in suicide attempters were significantly lower than in the control groups. Nevertheless, serum (HDL) levels in male and female suicide attempters were significantly higher than in the control group. Furthermore, NLR was significantly lower in the subjects with suicide attempts compared with the controls.

Conclusions: Lower concentrations of (TG), (TC) and (LDL) along with higher NLR were associated with non-violent suicide attempts. These findings might be an effective tool in screening suicide risk in young adults.

Background: Epidemiology of maxillofacial injuries vary depending on geographic location, culture and socioeconomic condition. This study assessed etiology and pattern of facial fractures in children reported at Burdwan Dental College and Hospital, Burdwan, West Bengal, India.

Methods: Clinical files of 206 children with facial fractures were evaluated retrospectively. Diagnosis of fractures were confirmed by radiographic examination. Study period was from July 2018 to June 2022. Data collected were age and sex of the patient, site of fracture, and etiology of trauma. Descriptive statistics were used for statistical analysis with a P-value less than 0.05.

Results: There were 127 (61.7%) males and 79 (38.3%) females with a male to female ratio of 1.6:1. Within the study sample, the majority of facial fractures (n= 146, 70.9%) belonged to 6-to-9-year age group. Overall, falls (44.2%) and motor vehicles accidents (31.5%) were the two leading causes of trauma. Mandible fracture was the most common, accounting for 72.8% of cases. 74 patients (35.9%) with facial fracture had dental injuries.

Conclusions: Male predominance in facial fracture is seen. With age, frequency of facial fractures tends to increase. Falls are the main cause of facial fracture and mandible is the most common anatomic location.
