Abstract
As the popularity of electric bicycles (e-bikes) continues to surge, the number of accidents involving them has commensurately increased. A significant factor contributing to the high fatality rate in these accidents is the low usage of helmets among e-bike riders. Helmets have been proven to reduce the severity of injuries, yet their usage remains unexpectedly low. This issue is particularly pronounced among college students, the primary buyer group for e-bikes. Regrettably, there is a lack of research exploring their intentions to wear helmets. Understanding determinants of their intentions to wear helmets is crucial in promoting safe e-bike travel. Therefore, the present study aims to develop an integrated theoretical model that combines the Theory of Planned Behavior (TPB) and the Health Belief Model (HBM) to examine the factors influencing e-bike riders' helmet-wearing intentions among college students. Additionally, two variables-descriptive norms and law enforcement-are incorporated. The results indicate that the integrated model accounts for 76% of the variance in helmet-wearing intention, surpassing single-theory models. Specifically, the TPB accounts for 65%, while the HBM explains 53%. Notably, law enforcement emerges as the most influential factor, highlighting the crucial role of enforcing regulations and promoting awareness. Other significant factors include subjective and descriptive norms, attitudes, perceived benefits, perceived susceptibility, perceived barriers, and perceived severity. These findings provide valuable insights for policy development and targeted interventions aimed at improving helmet wear rates among e-bike riders, especially among the college student population.

Abstract
Management of severe pediatric trauma remains challenging. Injury patterns vary according to patient age and trauma mechanism. This study analyzes trauma mechanisms in deceased pediatric patients. Fatal pediatric trauma cases aged 0-18 years who underwent forensic autopsy in the Federal State of Berlin, Germany, between 2008 until 2018 were enrolled in this retrospective study. Autopsy protocols were analyzed regarding demographic characteristics, trauma mechanisms, injury patterns, resuscitation measures, survival times as well as place, and cause of death. 71 patients (73% male) were included. Traffic accidents (40%) were the leading cause of trauma, followed by falls from height > 3 m (32%), railway accidents (13%), third party violence (11%) and other causes (4%). While children under 14 years of age died mostly due to traumatic brain injury (59%), polytrauma was the leading cause of death in patients > 14 years (55%). Other causes of death were hemorrhage (9%), thoracic trauma (1%) or other (10%). A suicidal background was proven in 24%. In the age group of > 14 years, 40% of all mortalities were suicides. Cardiopulmonary resuscitation was carried out in 39% of all patients. 42% of the patients died at the scene. Children between 0 and 14 years of age died most frequently from traumatic brain injury. In adolescents between 14 and 18 years of age, polytrauma was mostly the cause of death with a high coincidence of suicidal deaths. The frequency of fatal traffic accidents and suicides shows the need to improve accident and suicide prevention for children and adolescents.

An analysis of neutrophil-to-lymphocyte ratios and monocyte-to-lymphocyte ratios with six-month prognosis after cerebral contusions. Front Immunol 2024; 15:1336862. [PMID: 38545111 PMCID: PMC10967015 DOI: 10.3389/fimmu.2024.1336862] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Accepted: 02/27/2024] [Indexed: 04/10/2024] Open
Abstract
Background and purpose Neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) have been identified as potential prognostic markers in various conditions, including cancer, cardiovascular disease, and stroke. This study aims to investigate the dynamic changes of NLR and MLR following cerebral contusion and their associations with six-month outcomes. Methods Retrospective data were collected from January 2016 to April 2020, including patients diagnosed with cerebral contusion and discharged from two teaching-oriented tertiary hospitals in Southern China. Patient demographics, clinical manifestations, laboratory test results (neutrophil, monocyte, and lymphocyte counts) obtained at admission, 24 hours, and one week after cerebral contusion, as well as outcomes, were analyzed. An unfavorable outcome was defined as a Glasgow Outcome Score (GOS) of 0-3 at six months. Logistic regression analysis was performed to identify independent predictors of prognosis, while receiver characteristic curve analysis was used to determine the optimal cutoff values for NLR and MLR. Results A total of 552 patients (mean age 47.40, SD 17.09) were included, with 73.19% being male. Higher NLR at one-week post-cerebral contusion (adjusted OR = 4.19, 95%CI, 1.16 - 15.16, P = 0.029) and higher MLR at admission and at 24 h (5.80, 1.40 - 24.02, P = 0.015; 9.06, 1.45 - 56.54, P = 0.018, respectively) were significantly associated with a 6-month unfavorable prognosis after adjustment for other risk factors by multiple logistic regression. The NLR at admission and 24 hours, as well as the MLR at one week, were not significant predictors for a 6-month unfavorable prognosis. Based on receiver operating characteristic curve analysis, the optimal thresholds of NLR at 1 week and MLR at admission after cerebral contusion that best discriminated a unfavorable outcome at 6-month were 6.39 (81.60% sensitivity and 70.73% specificity) and 0.76 (55.47% sensitivity and 78.26% specificity), respectively. Conclusion NLR measured one week after cerebral contusion and MLR measured at admission may serve as predictive markers for a 6-month unfavorable prognosis. These ratios hold potential as parameters for risk stratification in patients with cerebral contusion, complementing established biomarkers in diagnosis and treatment. However, further prospective studies with larger cohorts are needed to validate these findings.

Abstract
E-bikes have become one of China's most popular travel modes. The authorities have issued helmet-wearing regulations to increase wearing rates to protect e-bike riders' safety, but the effect is unsatisfactory. To reveal the factors influencing the helmet-wearing behavior of e-bike riders, this study constructed a theoretical Push-Pull-Mooring (PPM) model to analyze the factor's relationship from the perspective of travel behavior switching. A two-step SEM-ANFIS method is proposed to test relationships, rank importance and analyze the combined effect of psychological variables. The Partial Least Squares Structural Equation Model (PLS-SEM) was used to obtain the significant influencing factors. The Adaptive Network-based Fuzzy Inference System (ANFIS), a nonlinear approach, was applied to analyze the importance of the significant influencing factors and draw refined conclusions and suggestions from the analysis of the combined effects. The PPM model we constructed has a good model fit and high model predictive validity (GOF = 0.381, R2 = 0.442). We found that three significant factors tested by PLS-SEM, perceived legal norms (β = 0.234, p < 0.001), perceived inconvenience (β = -0.117, p < 0.001) and conformity tendency (β = 0.241, p < 0.05), are the most important factors in the effects of push, mooring and pull. The results also demonstrated that legal norm is the most important factor but has less effect on people with low perceived vulnerability, and low subjective norms will make people with high conformity tendency to follow the crowd blindly. This study could contribute to developing refined interventions to improve the helmet-wearing rate effectively.

Abstract
Road traffic accidents are the leading cause of death by trauma. Delays in in first aid due, inter alia, to the long time to transfer traffic accident victims to hospital and the lack of pre-hospital emergency care, contribute to the increase in hospital mortality. This study aims to analyse the referral conditions for severe road traffic injuries and to assess their effect on the occurrence of hospital deaths in Benin. This is an analytical prospective cohort study conducted in road accident victims with a severe injury. Four groups of factors were studied: referral conditions, sociodemographic and victim-specific characteristics, factors related to the accident environment, and factors related to health services. A top-down binary stepwise logistic regression was the basis for the analyses. Nine point eight percent of severe trauma patients died after hospital admission (7.0-13.5). Associated factors were referral time greater than 1 hour (RR=5.7 [1.5-20.9]), transport to hospital by ambulance (RR=4.8 [1.3-17.3]) and by the police or fire department (RR=7.4 [1.8-29.7]), not wearing protective equipment (RR=4.5 [1.4-15.0]), head injuries (RR=34.8 [8.7-139.6]), and no upper extremity injuries (RR=20.1 [2.3-177.1]). To reduce the risk of hospital death in severe road traffic injuries, it is important to ensure rapid and medicalized referral of severe trauma patients in Benin.

Abstract
In Italy, in only 2018, 3310 people died in road traffic accidents, more than in any other European country. Since the revelation of this occurrence, the authors carried out an analysis aimed at investigating if there was a difference in the injury patterns among different road users. A retrospective post-mortem study on road traffic fatalities was performed, which had been autopsied at the Institute of Forensic Medicine of Milan. First, the authors analyzed the epidemiological data of all the 1022 road traffic accidents subjected to an autopsy from 2007 to 2019. Secondly, further analysis of individual autopsy reports was carried out. For this purpose, 180 autopsies belonging to 5 different categories were analyzed: car, pedestrian, motorbike, bicycle, and truck. Seventy-six percent of road traffic fatalities were male, 54% were between 10 and 49 years of age, and 62% of the patients died before arriving at a hospital. “Multiple injuries” was the main cause of death. Traumatic brain injuries were particularly high in pedestrians and cyclists. In car, motorbike, and truck fatalities, thoracic and abdominal injuries were the most frequent. Therefore, pedestrians and cyclists had a higher prevalence for traumatic head injuries, while car, motorcycle, and truck occupants, on the other hand, had a higher prevalence for thoracic and abdominal injuries.

Abstract
BACKGROUND Further reduction in road traffic accident (RTA) fatalities is a key priority in the European Union. Since data on injury patterns related to mortality in RTAs are scarce, the aim of this study was to analyze injury patterns and injury severity of in-hospital RTA fatalities in the Netherlands. METHODS All in-hospital deceased RTA victims in the Netherlands during the period 2015-2016 were analyzed. Data were obtained from the National Trauma Registry. Injury patterns, injury severity, accident and patient characteristics of road user groups were compared. RESULTS A total of 497 deceased RTA victims were analyzed, of which most were bicyclists. All analyzed motorcyclists had an ISS ≥ 16. Head trauma was most frequent in pedestrians (73.7%) and bicyclists (71.3%). Thorax trauma was most frequent in motorcyclists and motorists (60.9% and 65.8%, respectively). RTA victims younger than 25 years were more severely injured (median ISS 38, interquartile range [IQR] 29-46) compared to RTA victims aged over 75 years (median ISS 25, IQR 13-30). More than 10% of the severely injured (ISS ≥ 16) RTA victims was not transported to a level I trauma center. The majority of this group was older than 75 years. CONCLUSIONS Further prevention of head trauma is needed to reduce RTA fatalities, especially in bicyclists. Also, undertriage of severe trauma in elderly RTA victims is obvious and should be addressed in the early phases of trauma care, especially during prehospital triage and initial care at admission.

Traumatic brain injury among two-wheeled motor vehicle riders in Utsunomiya, Japan: a comparison between mopeds and motorcycles. Eur J Trauma Emerg Surg 2019; 47:1477-1482.

Abstract
PURPOSE Two-wheeled motor vehicles are dichotomized into mopeds and motorcycles (MCs) based on their engine capacity. While efforts have been made, mostly by European researchers, to evaluate the possible difference in the frequency/severity of riders' traumatic brain injury (TBI) between the two categories, the results have been inconsistent. METHODS To evaluate whether such differences exist in Japan, a single-center, retrospective observational study was conducted on two-wheeled motor vehicle riders wearing a helmet during high-energy road traffic accident (RTA). Between January 2011 and December 2017, 127 moped and 128 MC helmeted riders involved in RTAs had been treated in our institution. RESULTS Moped riders were significantly older than MC riders (50.7 ± 25.0 years vs. 35.1 ± 18.6 years, p = 0.04). The frequency of TBI was significantly higher in moped riders than in MC riders (21.3% vs. 10.9%; p = 0.03). However, the frequency of other bodily injuries did not differ significantly. Among the riders with TBI, neither injury severity nor outcomes differed significantly. Multivariate regression analysis showed that the presence of altered mental status was predictive of TBI (OR 23.398; 95% CI 9.187-59.586; p < 0.001). Moped riders trended to have a higher likelihood of sustaining TBI (OR 2.122; 95% CI 0.870-5.178; p = 0.098). CONCLUSIONS Mopeds are frequently utilized by elderly in Japan, which may have been causally associated with the higher frequency of TBI in moped riders, while other causes, including the difference in helmet type, may also be involved. This study is limited by its small sample size and retrospective design, and multi-center prospective studies are warranted.

Abstract
Background Little is known about functioning of the middle ear with advancing age. Objectives To estimate the prevalence and describe tympanometric patterns of sub-clinical middle ear malfunctions,( S-MEM) in elderly patients. It also assessed clinical factors that could predict S-MEM. Methods Cross-sectional, analytical study of patients aged ≥ 60 years in a tertiary hospital in Nigeria between 2011–2014. Pure tone audiometry (PTA), tympanometry and acoustic reflexes were recorded. S-MEM was based on audiometric and tympanometric evident abnormalities. Descriptive, univariate and multivariate analyses performed to detect independent clinical predictors of S-MEM at p-value of <0.05. Results 121 patients , M: F of 1.1:1. Mean age was 70.1 ± 6.2 years, 77.7% were married. Prevalence of S-MEM was 21.5%. Abnormal tympanometric tracings were type AS>C>B>AD. The parameters that were statistically-significant on univariate analyses were subjected to logistic regression analysis which confirmed previous head injury, diabetes, osteoarthritis of knee joint, and absent acoustic reflex as clinical predictors for S-MEM. Conclusion 21.5% of elderly Africans had subclinical abnormalities in their middle ear functioning, mostly with type AS tympanogram. Independent clinical predictors of S-MEM included previous head injury, diabetes, history of osteoarthritis of knee joints, and absent acoustic reflex.

Abstract
Background Despite reductions in youth pedestrian and bicyclist deaths over the past two decades, these injuries remain a substantial cause of morbidity and mortality for children and adolescents. There is a need for additional information on non-fatal pediatric pedestrian injuries and the role of traumatic brain injury (TBI), a leading cause of acquired disability. Methods Using a multi-year national sample of emergency department (ED) records, we estimated annual motorized-vehicle related pediatric pedestrian and bicyclist (i.e. pedalcyclist) injury rates by age and region. We modeled in-hospital fatality risk controlling for age, gender, injury severity, TBI, and trauma center status. Results ED visits for pediatric pedestrian injuries declined 19.3% (95% CI 16.8, 21.8) from 2006 to 2012, with the largest decreases in 5-to-9 year olds and 10-to-14 year olds. Case fatality rates also declined 14.0%. There was no significant change in bicyclist injury rates. TBI was implicated in 6.7% (95% CI 6.3, 7.1) of all pedestrian and bicyclist injuries and 55.5% (95% CI 27.9, 83.1) of fatalities. Pedestrian ED visits were more likely to be fatal than bicyclist injuries (aOR = 2.4, 95% CI 2.3, 2.6), with significant additive interaction between pedestrian status and TBI. Conclusions TBI in young pedestrian ED patients was associated with a higher risk of mortality compared to cyclists. There is a role for concurrent clinical focus on TBI recovery alongside ongoing efforts to mitigate and prevent motor vehicle crashes with pedestrians and bicyclists. Differences between youth pedestrian and cycling injury trends merit further exploration and localized analyses, with respect to behavior patterns and interventions. ED data captures a substantially larger number of pediatric pedestrian injuries compared to crash reports and can play a role in those analyses.

Abstract
INTRODUCTION Pediatric road traffic injuries remain a significant cause of death and disability in many countries in Asia, despite the implementation of road traffic safety laws. We aim to describe the injuries, the use of restraints among road users, and risk factors associated with severe injuries for children in Singapore. METHODS We performed a retrospective chart review of road traffic injuries presenting to the only two pediatric tertiary care hospitals in Singapore, from January 2012 to April 2016. We included children <16years old presenting to the emergency departments within 24h after injury (pedestrian, bicycle, motorcycle, motor vehicle). We calculated the frequencies for specific injury mechanisms, injury severity scores (ISS), and in-hospital outcomes of severe injuries (death, urgent resuscitation and emergent surgery). We performed a multivariate logistic regression to determine risk factors associated with severe injury. RESULTS There were 2468 patients during the study period. The mean age was 7.9 years (SD 4.7); 60.1% of road injuries involved motor vehicle occupants (1483/2468). Most bicyclist/motorcyclists were not wearing helmets (70.0%, 245/350) and 51.1% of motor vehicle passengers (758/1483) were not restrained. Compared to motor vehicle passengers, pedestrians (adjusted OR 2.38, 95% CI 1.41-3.99), bicyclists (adjusted OR 2.12, 95% CI 1.04-4.32) and motorcyclists (adjusted OR 6.09, 95% CI 2.04-18.24) were more likely to sustain severe injuries. CONCLUSION Child pedestrians, bicyclists and motorcyclists are especially vulnerable for severe injures. Further injury prevention efforts must focus on the enforcement of legislation to protect these high-risk groups.

Abstract
We have previously shown that early treatment with fresh frozen plasma (FFP) is neuroprotective in a swine model of hemorrhagic shock (HS) and traumatic brain injury (TBI). However, it remains unknown whether this strategy would be beneficial in a more clinical polytrauma model. Yorkshire swine (42-50 kg) were instrumented to measure hemodynamic parameters, brain oxygenation, and intracranial pressure (ICP) and subjected to computer-controlled TBI and multi-system trauma (rib fracture, soft-tissue damage, and liver injury) as well as combined free and controlled hemorrhage (40% blood volume). After 2 h of shock (mean arterial pressure, 30-35 mm Hg), animals were resuscitated with normal saline (NS; 3×volume) or FFP (1×volume; n=6/group). Six hours postresuscitation, brains were harvested and lesion size and swelling were evaluated. Levels of endothelial-derived vasodilator endothelial nitric oxide synthase (eNOS) and vasoconstrictor endothelin-1 (ET-1) were also measured. FFP resuscitation was associated with reduced brain lesion size (1005.8 vs. 2081.9 mm(3); p=0.01) as well as swelling (11.5% vs. 19.4%; p=0.02). Further, FFP-resuscitated animals had higher brain oxygenation as well as cerebral perfusion pressures. Levels of cerebral eNOS were higher in the FFP-treated group (852.9 vs. 816.4 ng/mL; p=0.03), but no differences in brain levels of ET-1 were observed. Early administration of FFP is neuroprotective in a complex, large animal model of polytrauma, hemorrhage, and TBI. This is associated with a favorable brain oxygenation and cerebral perfusion pressure profile as well as higher levels of endothelial-derived vasodilator eNOS, compared to normal saline resuscitation.
