Abstract
OBJECTIVES To describe the incidence of head and neck trauma related to electric bicycles and to characterize head and neck injury patterns seen in electric bicycle (eBike) users versus pedal bicyclists in the United States. METHODS The National Electronic Injury Surveillance System (NEISS) was queried from 2009 to 2020 for patients with head and neck injuries related to electric and pedal bicycles. Extracted data included patient demographics, injury patterns, hospital admission, and helmet use. Univariate chi-squared analyses were performed to compare demographics and injury patterns between bicycle groups. Effect sizes were reported with Cramer V values (V). RESULTS The incidence of eBike-related head and neck injuries increased from 2993 in 2009 to 9916 in 2020. Compared to pedal bicycle users, eBike users were more likely to have head injuries (60.4% vs. 52.0%) and fractures (10.9% vs. 6.0%), and were more likely to require hospitalization (20.6% vs. 10.4%). The effect size of helmet use was significantly greater in eBike users compared to pedal bicyclists when examining distributions of age group (V = 0.203 vs. V = 0.079), injury location (V = 0.220 vs. V = 0.082), and injury type (V = 0.162 vs. V = 0.059). Helmeted injuries in eBike users more commonly involved neck injuries and sprains, rather than head injuries and fractures. CONCLUSION Head and neck trauma related to eBike use is increasing in the United States. Injury patterns and admission rates reflect greater injury severity in eBike users compared to pedal bicyclists. Helmet use may be particularly beneficial in mitigating head and neck injury in eBike users. LEVEL OF EVIDENCE 3 Laryngoscope, 134:2734-2740, 2024.

Abstract
PURPOSE In modern societies, motorcycle accidents have become a great problem for health systems worldwide. In Spain, the size and the power of the engine of 2-wheel vehicles determine the type of driving license and the age at which these vehicles can be used (mopeds and motorcycles, which at the same time can have a small or large engine capacity). The objective of the present study was to analyze and characterize low- and high-power motorcycle accidents in Spain, between 2014 and 2020, both included and compared these categories with each other. METHODS Retrospective, descriptive, and observational study of motorcycle and moped accidents in Spain between 2014 and 2020, both included. RESULTS The mortality of motorcycle accident riders in Spain is associated with males aged between 30 and 40 years old, with a high-power motorcycle, and an A or A1 driver's license, who is 6.7 times more likely to die in crossings and highways than a moped, while wearing a helmet, and if not, this increases to 4.89 times. During the COVID-19 pandemic, an increase in death at 24 h after a high-power motorcycle accident was observed, as compared with a large reduction in the total medical assistance provided in 2019-2020. CONCLUSIONS High-power motorcycles had higher scores in mortality and morbity rates than low-power ones, with a significant increase in mortality during the pandemic, even though number of accidents and medical assistance provided were drastically reduced.

Abstract
Background and Objectives: In recent years, electronic scooters (e-scooters) have gained popularity, whether for private use or as a publicly available transportation method. With the introduction of these vehicles, reports of e-scooter-related accidents have surged, sparking public debate and concern. The aim of this study was to analyze the epidemiological data, characteristics, and severity of traumatic brain injury (TBI) related to e-scooter accidents. Materials and Methods: This retrospective case series evaluated patients who were admitted to the three largest neurosurgery clinics in Riga, Latvia, from the time period of April to October in two separate years-2022 and 2023-after e-scooter-related accidents. The data were collected on patient demographics, the time of the accident, alcohol consumption, helmet use, the type of TBI, other related injuries, and the treatment and assessment at discharge. Results: A total of 28 patients were admitted with TBI related to e-scooter use, with a median age of 30 years (Q1-Q3, 20.25-37.25), four individuals under the age of 18, and the majority (64%) being male. In 23 cases, the injury mechanism was falling, in 5 cases, collision. None were wearing a helmet at the time of the injury. Alcohol intoxication was evident in over half of the patients (51.5%), with severe intoxication (>1.2 g/L) in 75% of cases among them. Neurological symptoms upon admission were noted in 50% of cases. All patients had intracranial trauma: 50% had brain contusions, 43% traumatic subdural hematoma, and almost 30% epidural hematoma. Craniofacial fractures were evident in 71% of cases, and there were fractures in other parts of body in three patients. Six patients required emergency neurosurgical intervention. Neurological complications were noted in two patients; one patient died. Conclusions: e-scooter-related accidents result in a significant number of brain and other associated injuries, with notable frequency linked to alcohol influence and a lack of helmet use. Prevention campaigns to raise the awareness of potential risks and the implementation of more strict regulations should be conducted.

Abstract
INTRODUCTION In recent years, there has been a significant increase in mortality among motorcyclists, which warrants a need to analyze the epidemiology and pattern of injuries among road users in Malaysia. Hence, prioritizing road safety in the government policy by implementing targeted actions is justified to reduce injury and fatality. MATERIALS AND METHODS Cases of road accident deaths in motorcyclists received by UKM Medical Centre were studied over a period of 10 years, that is, between 2010 and 2019. This study was based on forensic autopsy records database and forensic autopsy. RESULTS The most affected age group by road fatalities were young men. The most common injuries were intracranial hemorrhage (74%), thoracic hemorrhage (73%), and lung laceration (85.7%). About 39 (31%) fatally injured riders were positive for illicit drug and/or alcohol. CONCLUSIONS This study showed that men in the third decade of life are the major victims of motorcycle fatalities. Hence, urgent measures are necessary to establish road safety policy to reduce such fatalities.

Abstract
INTRODUCTION Under current law in our rural state, there is no universal requirement for motorcyclists to wear helmets. Roughly 500 motorcycle crashes are reported by the state each year and only a fraction of those riders wear helmets. We sought to determine the difference in injury patterns and severity in helmeted versus non-helmeted riders. METHODS Retrospective review (2014-2018) of a single level 1 trauma center's registry was done for subjects admitted after a motorcycle collision. Demographic, injury and patient outcome data were collected. Patients were stratified by helmet use (n = 81), no helmet use (n = 144), and unknown helmet use (n = 194). Statistical analysis used Student's t-test or Pearson's χ2p-value ≤0.05 as significant. State Department of Transportation data registry for state level mortality and collision incidence over the same time period was also obtained. RESULTS Of the 2,022 state-reported motorcycle collisions, 419 individuals admitted to our trauma center were analyzed (21% capture). State-reported field fatality rate regardless of helmet use was 4%. Our inpatient mortality rate was 2% with no differences between helmet uses. Helmeted riders were found to have significantly fewer head and face injuries, higher GCS, lower face, neck, thorax and abdomen AIS, fewer required mechanical ventilation, shorter ICU length of stay, and had a greater number of upper extremity injuries and higher upper extremity AIS. CONCLUSIONS Helmeted motorcyclists have fewer head, face, and cervical spine injuries, and lower injury severities: GCS and face, neck, thorax, abdomen AIS. Helmeted riders had significantly less mechanical ventilation requirement and shorter ICU stays. Non-helmeted riders sustained worse injuries. Practical Applications: Helmets provide safety and motorcycle riders have a 34-fold higher risk of death following a crash. Evaluating injury severities and patterns in motorcycle crash victims in a rural state with no helmet laws may provide insight into changing current legislation.

Abstract
OBJECTIVE E-scooter use has grown rapidly in the United States. Its rise in popularity has coincided with the promotion of cycling in many cities, but more needs to be known about how these transportation modes compare to determine if cycling should serve as an appropriate benchmark for policy decisions and safety expectations regarding e-scooters. METHODS We examined characteristics of adults seeking treatment in a Washington, DC, emergency department (ED) for injuries associated with riding e-scooters during 2019 (n = 99) or bicycles during 2015-2017 (n = 337). RESULTS E-scooter incidents less frequently involved moving vehicles (13.1% vs. 37.7%) or occurred on roads (24.5% vs. 50.7%) than cycling incidents. A smaller proportion of injured e-scooter riders were ages 30-49 (32.3% vs. 48.4%) and a larger proportion were 50 and older (34.3% vs. 22.6%) or female (45.5% vs. 29.1%). Distal lower extremity injuries were more common among e-scooter riders (13.1% vs. 3.0%; RR, 2.76; 95% CI, 1.79-3.54), and injuries to the proximal upper extremity (9.1% vs. 20.5%; RR, 0.49; 95% CI, 0.24-0.92) or chest, abdomen, and spine (3.0% vs. 14.0%; RR, 0.24; 95% CI, 0.07-0.70) were less common. Head injury rates were similar, but e-scooter riders more often experienced concussion with loss of consciousness (4.0% vs. 0.6%; RR, 3.03; 95% CI, 1.20-4.09) and were far less likely to wear helmets (2.0% vs. 66.4%). Estimated ED presentation rates per million miles traveled citywide were higher among e-scooter riders than cyclists (RR, 3.76; 95% CI, 3.08-4.59). CONCLUSIONS E-scooters and bicycles are both popular forms of micromobility, but the characteristics of riders injured on them, the ways in which they become injured, and the types of injuries they sustain differ substantially. E-scooter rider injury rates, though currently high, may decrease as they gain experience; however, if the number of new users continues to climb, they will persist in using the ED more often than cyclists per mile that they travel.

Abstract
OBJECTIVE Motorcycle helmets are the most common and effective protective device to reduce head injuries and mortality in crashes among powered two-wheeler riders. Even if they are globally recognized as effective, there are still concerns regarding their correct use, which is necessary to achieve maximum head protection. The goal of this systematic review is to assess which characteristics of helmet design and use showed a positive influence on rider safety, in order to provide insights to improve end-user helmet usage. METHODS A literature search was carried out combining two sets of keywords, one related with either motorcycle or rider and the other referring to either protective equipment or injuries. After the exclusion of duplicates, 977 papers were screened by reviewers, thus identifying 32 papers that were analyzed in group discussions. RESULTS Among the papers included in this study, no strong conflicting conclusions emerged in their results. The studies focusing on the use of different types of helmets highlighted that full-face helmets, compared with other standard helmets, have a positive influence on head injuries and facial injuries. Correct fastening was clearly beneficial for head and facial injuries, induced injuries, and helmet ejection. CONCLUSIONS This systematic review provides important insights to improve the usage of helmets by end-users. Correct fastening is a crucial factor to avoid helmet roll-off during a crash. Most studies agreed that full-face helmets provide higher protection in comparison with other standard helmets, especially for facial injuries, and no negative influence with respect to neck and spinal injuries.

Abstract
OBJECTIVES Composite road safety performance indicators (RSPIs) are useful tools in regional road safety planning. Among the indicators and data calculated by the World Health Organization (WHO), information on the effectiveness of law enforcement on various risk factors for road casualties were provided, which can be considered as qualitative indicators. The purpose of this study is to analyze the performance indicators related to the percentage of helmet and seat-belt use versus the qualitative enforcement scores attributed by WHO. METHODS This analysis was performed for 30 member states of WHO and will show how and with what degree of efficiency the qualitative output of the enforcement score acts versus the input percentage of seat-belt and helmet use. The qualitative nature of the output index has led us to depart the traditional analysis of crisp numerical indicators related to road safety performance and to consider data as imprecise or fuzzy indices. In this study we used two methods including imprecise DEA-based CIs and fuzzy DEA-based CIs, respectively. RESULTS Results show that the clear score achieved by the Imprecise DEA-based CI model is easy to interpret and use. Whereas, in the Fuzzy DEA-based CI model, the fuzzy indicator scores obtained based on the level of several probabilities are strong in capturing the uncertainties related to human behavior. CONCLUSIONS Both RSPIs are applicable with slight differences that were in the order of countries and the ease of reading the results. We also found that each method has different strengths and that the FDEA-based CIs method is more accurate and more in line with the inputs than the IDEA-based CIs method.

Abstract
BACKGROUND Electric scooters (e-scooters) are becoming increasingly common in major urban areas worldwide. Cities in some countries have even piloted programmes to promote their use to reduce general vehicular traffic. There have, however, been widespread media reports outlining concerns about their safety. We decided to investigate these concerns by reviewing the records of patients who presented to our center, a Level 1 Major Trauma Center in the United Kingdom, with orthopedic injuries associated with e-scooter use. METHODS We reviewed the electronic medical records of all patients who presented to our center from January 2018 to January 2020 with e-scooter associated fractures. Demographic, injury, and surgical data were collected to characterize the types of e-scooter-related fractures and to investigate the frequency of such injuries over the duration of our search. A literature review of MEDLINE and EMBASE was performed to investigate specifically orthopedic injuries caused by electric scooter use. RESULTS Six patients were identified (3 male, 3 female; mean age 35.43 years) who had sustained a variety of injuries. The presentation and clinical outcomes are presented. Three patients required operative management, and three patients were managed conservatively. CONCLUSION This case series demonstrates an increasing frequency of significant orthopedic injury associated with e-scooter use treated at our center over the course of two years. This small series highlights an important problem given that this increase has occurred despite electric scooter usage in public spaces being illegal. Legalization might result in further increase in the incidence of injury.

Abstract
AIM E-scooters were introduced to New Zealand in 2018 as a means of city transport. Since their introduction, their use has resulted in high injury rates. No studies have directly compared e-scooters to other forms of transport. METHOD The Auckland City Hospital trauma registry was retrospectively searched for patients admitted with an e-scooter injury. A comparison group of patients admitted with an injury secondary to cycling during the same period was collected. RESULTS 178 patients were identified: 69 with e-scooter injuries and 109 with injuries sustained while cycling. The hospitalisation rate for e-scooter injuries was 326 hospitalisations per million hours. There was a significant difference found in blood ethanol levels (18.6 vs 6.4% positive, p-value=0.01), mechanism of injury (isolated falls: 87 vs 60.6%), time of injury (55.1 vs 40.4% between 5pm-8am) and protective gear use (worn in 10.1 vs 78.9%). No differences were found in injury severity, ICU admissions, length of stay or mortality. CONCLUSION This study demonstrates a concerningly high e-scooter-related hospitalisation rate and suggests e-scooters are currently not as safe as cycling. Strategies to improve e-scooter safety are needed and could include zero tolerance for alcohol, mandatory protective gear, restricted operating times and changes in road laws.

Abstract
INTRODUCTION The U.S. experience with motorcycle helmets affords an important insight into the responses of adolescents to age-specific laws. Political contention has led to a number of U.S. state law changes back and forth between universal and age-specific laws. Because both kinds of law require adolescent motorcyclists to wear helmets, relatively few studies have focused on how the law type affects their behavior. METHOD Differential behavior is tested by a systematic review of literature, leading to a meta-analysis, in relation to the experience of various states' motorcycle helmet laws. An electronic search was conducted for before-and-after studies in U.S. states that include data on adolescent helmet usage - both with a universally applicable motorcycle helmet law, and with an age-restricted law (usually, under-21 or under-18) - from observational, injury or fatality records for a certain period (e.g., 12 months) pre and post the state law change. RESULTS The search yielded ten studies, including two that compared a set of age-specific law states with a set of universal law states over the same time period. Heterogeneity analysis of seven single-state studies with raw data revealed an acceptable fit for a random-effects model. Additional noncompliance with age-restricted laws was indicated by an attributable percentage among exposed of over 65% and odds ratio exceeding 4. CONCLUSIONS About two-thirds of adolescent noncompliance with age-restricted motorcycle helmet usage laws disappears with universal applicability. Evidence from numerous international studies of youth reaction to helmet laws suggests that a large part of the greater compliance with universal laws is due to their conveying a more convincing message that helmets afford protection against injury. Practical Applications: The meta-analysis provides fresh, young-rider perspective on the continuing debate over motorcycle-helmet laws. Broader insight into adolescent psychology suggests considering alternatives to age-restricted laws more widely in safety and health policy.

Abstract
INTRODUCTION Motorcycles are colloquially referred to as "donorcycles" among medical staff. However, the actual impact of helmet laws and helmet use on organ donation is unknown. Michigan's 35-year-old universal helmet law (UHL) was repealed in April 2012 and replaced by a partial-helmet law. We hypothesized that there would be an increase in organ donation rates from unhelmeted motorcyclist fatalities. METHODS Michigan's Gift of Life Michigan organ donation database was queried from April 2008 through May 2015 in conjunction with the Michigan Trauma Quality Improvement Program database from the same time period. All in-hospital motorcycle crash fatalities were examined. RESULTS A three-fold increase was found in the rate of organ donation for unhelmeted motorcyclists compared to helmeted motorcyclists (p = 0.006). Motorcycle crash fatalities tended to be younger in age after the UHL repeal with an average age of 32.8 years versus 40.8, however, this finding was not statistically significant (p = 0.071). Additionally, there was no significant difference in organ donation rates pre-UHL repeal (2008-2012) versus post-repeal (2012-2015). CONCLUSIONS This is the first study to demonstrate an increased rate of organ donation among unhelmeted motorcyclist fatalities compared to helmeted rider fatalities. There was no significant increase in the rate of organ donation following the Michigan UHL repeal. However, we identified that some motorcycle crash fatalities were from illegally unhelmeted riders in the past, prior to the repeal. Practical Application: Unhelmeted motorcyclists are three times more likely than helmeted riders to become organ donors, possibly due to the well documented increase in severe traumatic brain injuries in this population. From a public health perspective, helmets should be required for all motorcyclists and efforts to advocate in favor of helmet legislation should be supported by trauma systems and health professionals.

Abstract
INTRODUCTION There has been controversy regarding whether headgear use in women's lacrosse will affect the rate of head and musculoskeletal injuries. The purpose of this study was to investigate the effect of mandated headgear use on the rate of head and musculoskeletal injuries in high school women's lacrosse. METHODS This was a prospective cohort study of eight high school women's lacrosse teams and their game op-ponents who were mandated to wear F3137 headgear for the 2017 and 2018 seasons. Athletic trainers documented all injuries that occurred as a result of participation on the lacrosse teams. Injury rates in the headgear cohort were compared to a retrospective (control) cohort from the High School Reporting Information Online injury data reports. RESULTS Over the study period, 17 total injuries were reported in the headgear cohort during 22,397 exposures for an injury rate of 0.76 injuries per 1,000 athlete-exposures. The headgear cohort demonstrated significant decreases in rates of in-game head and face injury (RR 0.141, 95% CI [0.004, 0.798]), in-game concussion (RR 0.152, 95% CI [0.004, 0.860]), and practice trunk and extremity injury (RR 0.239, 95% CI [0.049, 0.703]) when compared to the control cohort. CONCLUSION Mandated use of headgear was shown to be effective at lowering the rate of head or face injury and concussions in women's lacrosse. Additionally, mandated headgear use was also shown to lower the rate of injury to body locations other than the head or face during practice. To our knowledge, this is the first study to demonstrate a decrease in injury rates associated with ASTM approved headgear in women's lacrosse.

Abstract
INTRODUCTION Norwegian authorities encourage people to commute by bicycle to improve public health, decrease rush-hour traffic jams and reduce pollution. However, increasing the number of bicyclists, especially in the rush-hour traffic, may increase the number of serious bicycle injuries. OBJECTIVE To explore trends in hospitalized bicycle injuries at a Norwegian level I trauma centre during the last decade. METHODS Data was extracted from the prospectively registered institutional trauma registry. We identified patients admitted after bicycle injuries between 2005 and 2016. RESULTS A total of 1543 patients were identified. Median age was 40 years (range 3-91) and 73 % were males. The majority of weekday injuries occurred in the morning and during the afternoon rush-hour, peaking at 8 am. and 4 pm. The annual number of admitted bicycle injuries increased from 79 to 184 during the study period. Also, an increase in the share of bicyclists using helmets was observed. The median Injury Severity Score (ISS) of 10 remained unchanged. 63 % had serious trauma (ISS ≥ 9), while 34 % suffered severe trauma (ISS ≥ 16). The absolute number of both serious and severe trauma increased annually. 36 % had head and neck injuries, while 16 % had chest injuries graded with Abbreviated Injury Scale ≥3. Loss of consciousness with Glasgow Coma Scale score <9 was seen in 7%. Median length of hospitalization was 3 days, and 39 % had surgery in one or more body regions. The 30-day mortality was 2.3 %. CONCLUSIONS The number of admitted bicycle injuries to our trauma centre is increasing. Rush-hour injuries dominate during weekdays. Bicycle injuries can be devastating and deserve more public attention to promote road safety.

Abstract
OBJECTIVES To determine the prevalence of helmet use in Chiang Mai province in Thailand and identify the association between helmet use, externalized behaviors, and other risk-taking behaviors. METHODS A cross-sectional study was conducted using the Youth Risk Behavior Survey, Thai version. Risky motor vehicle behaviors and other risk-taking behaviors of 4,372 adolescents were measured. Behavioral problems from the Youth Self-Report were also obtained from all participants. RESULTS A total of 2,981 adolescents (68.2%) reported motorcycle riding, of which, 36.3% reported unprotected riding. Females, younger age, attending secondary school, and those with academic underachievement were related to the unprotected riding group. Unprotected riding was significantly associated with other risky traffic behaviors and also related to other risk-taking behavior such as violence and substance use. Significantly higher behavioral problems scores were found in unprotected riding adolescents (p < 0.001). CONCLUSIONS The prevalence of unprotected riding and other risk behaviors in Thai adolescents were high. Safety traffic riding campaigns should start in late primary school focusing on those females with poor academic achievement.

Abstract
OBJECTIVE The aim of the present study was to investigate the relationship between bicycle helmet use and safety behavior at signalized intersections. Two hypotheses were investigated: The first states that bicycle helmet use leads to risker behavior because of the increased sense of protection (risk compensation), the other states that helmeted cyclists have a general inclination toward safer behavior (safety package) and that helmet use is one of several behaviors for improving safety. METHOD Based on video recordings of 1031 cyclists at 12 signalized intersections in Denmark, two indicators of risky behavior were compared between helmeted and unhelmeted cyclists: Speed and time after the onset of yellow at which the cyclists crossed the stop line. Linear regression models were developed with gender, type of bicycle, and intersection characteristics as predictor variables, in addition to helmet use. RESULTS Helmeted and unhelmeted cyclists do not differ in how many seconds after the onset of yellow they cross the stopping line. This is consistent with the absence of both risk compensation and safety package, alternatively with a general inclination of helmeted cyclists toward safer behavior which is about offset by risk compensation. Helmeted cyclists had higher speed on average, which indicates that risk compensation may occur. However, the higher speed may also be due to the generally better fitness of helmeted cyclists which is likely to result from larger cycling volumes. Moreover, the effect of helmet use on speed may be overestimated because of a lack of control for potential confounding variables. The results show further that, regardless of helmet use, before-red (lights on a separate bicycle signal shift to red before the main signal) is related to later crossings of the stop lane after the onset of yellow and that cyclists stop earlier on average at intersections with right-turn signals. CONCLUSIONS The results do not provide support for the position that promoting or mandating bicycle helmet use will have adverse safety effects because of more risky behavior among helmeted cyclists.

Abstract
OBJECTIVE In Vietnam, motorcycle riders comprise about three-quarters of road traffic fatalities, the most common cause of which is head injuries that can be prevented by wearing a helmet. This study aims to assess helmet-wearing behaviors in Ho Chi Minh City, the largest city in Vietnam. METHODS Eight rounds of observational studies were conducted in six randomly selected locations between July 2015 and April 2019. Given the multinomial nature of the outcome measure (not wearing a helmet; wearing a substandard helmet; wearing an unstrapped standard helmet; wearing a strapped standard helmet), a multinomial model was developed to estimate the level and trend of helmet use and identify the related individual and environmental factors. FINDINGS A total of 479,892 motorcycle riders were observed, over 90 % of whom were wearing helmets (range over the eight rounds: 92.5 %-96.0 %). However, the prevalence of correct helmet use (defined as wearing a strapped standard helmet) gradually declined from 80.8 % in round 1-55.6 % in round 8. Results from a multinomial model showed the probability of wearing a strapped standard helmet had declined by 22.4 percentage points from round 3 to round 8 while holding other factors constant (95 % CI: 21.8-23.0). The prevalence of correct use is 11.3 percentage points higher for adults than for children (95 % CI: 10.5-12.1). During the same period, unstrapped standard helmet use increased by 24.5 percentage points (95 % CI: 24.1-24.9); substandard helmet use declined but remained high. CONCLUSION The upward trend of incorrect helmet wearing behaviors and wearing substandard helmets sends a rallying call for multisectoral interventions.

Abstract
OBJECTIVE In Bogotá, Colombia, motorcyclists represent a concern as the proportion of motorcycle users between 2013 and 2018 has increased from 18% to 35%. Despite available risk reduction strategies, the fatality rates are also growing, notably in young adults (15-29 years old). This study aims at identifying correct helmet use patterns and its relationship with official records of injuries and casualties in the city over time. METHODS Between 2015 and 2018, semiannual observational studies of motorcycle users in six randomly selected sites in Bogotá were conducted. Data was collected and analyzed on the number of occupants per vehicle (driver and passengers), gender, approximate age, type of helmet, and whether it was correctly used (strapped) or not. Bivariate and multivariate analyses were performed to identify the determinants of correct helmet use. Additionally, a spatial analysis was conducted to estimate the relationship between motorcycle's casualties and correct use of the helmet (full-face helmet use) prevalence. RESULTS A total of 77,932 motorcycles were observed, showing a high prevalence of helmet use (99% for drivers and passengers), but only 88% use it correctly (89% drivers and 82% passengers). The presence of enforcement (camera or police personnel) increases the correct use of the helmet, especially in principal roads. Female, adults, and single riders are more likely to correctly wear the helmet. Finally, there is a relationship between the concentration of the fatalities and the incorrect helmet use in 80% of the observational sites. CONCLUSIONS Incorrect helmet use has been found by the study to be related to higher mortality among motorcycle occupants in Bogotá. Our data shows that enforcement increases correct helmet use with the potential to reduce deaths among motorcycle occupants.

Abstract
BACKGROUND Alcohol-involved riders tend to engage in other risk-taking behaviours such as un-helmeted riding which could further increases injury severity. The combined effect of alcohol-involved and un-helmeted riding on fatal injuries is rarely investigated. This study investigated the interaction effect between blood alcohol concentration and helmet use on fatal injuries. METHODS This study used the National Taiwan Traffic Crash Dataset for the period from 2011 to 2015. Data on road crashes involving a motorcycle and an automobile were extracted and analysed. Multiple logistic regression models were used to calculate the adjusted odds ratio (AOR). We calculated an interaction effect for blood alcohol concentration and helmet use based on STROBE guidelines. RESULTS There were a total of 669,292 motorcyclist casualties; among these casualties, 3459 (0.5 %) motorcyclists sustained fatal injuries. Alcohol-involved riders were 9.47 times (AOR = 9.47; 95 % CI = 8.75-10.25) more likely than sober ones to sustain fatal injuries. Alcohol-involved and un-helmeted riders were approximately 18 times (AOR = 18.1; CI: 15.9-20.4) more likely to sustain fatal injuries than sober and helmeted riders. Riders involved in head-on crashes and approach-turn motorcycle crashes had an increased probability of sustaining fatal injuries by 240 % (AOR = 3.4; 95 % CI = 2.91-4.09) and 132 % (AOR = 2.3; 95 % CI = 2.016-2.67), respectively. CONCLUSIONS This study found that alcohol-involved riding acts synergistically with un-helmeted riding to increase motorcyclist injury severity.

Abstract
INTRODUCTION Androgenetic alopecia is the most common form of hair loss in both sexes. In recent studies, low-level light therapy (LLLT) has been established as an effective treatment for alopecia. The purpose of this study was to evaluate the safety and efficacy of LLLT using a new helmet-type device for the treatment of androgenetic alopecia. METHOD A randomized, sham device-controlled, double-blind clinical trial was conducted at 2 institutions. Sixty participants diagnosed with androgenetic alopecia aged from 19 to 65 years were recruited. LLLT was performed through a helmet-type device that emitted light with a mean output power of 2.36 mW/cm at a wavelength of 655 nm. Participants were divided into 2 groups, which respectively used the experimental device and a sham device. After tattooing at the central point of the vertex, phototrichograms at that point were obtained at 0, 8, and 16 weeks. The primary endpoint of the study was the difference in the rate of change of hair density between the test group and the control group. RESULTS Comparing the results at baseline and week 16, the experimental group showed an increase in hair density of 41.90 hairs/cm and an increase in hair thickness of 7.50 μm, whereas the control group showed an increase of 0.72 hairs/cm and a decrease of 15.03 μm, respectively (P < .001). No adverse events or side effects occurred. CONCLUSION LLLT showed a significant effect on increasing hair density in patients with androgenetic alopecia. LLLT could be a safe and effective treatment for androgenetic alopecia in both sexes.

Abstract
OBJECTIVE Many developing countries experience a high death toll among motorcycle users (both drivers and passengers), primarily due to a relatively low rate of helmet use resulting from ineffective helmet law enforcement. The objectives of this study are to explore the change in helmet use behavior due to helmet use enforcement by closed-circuit television (CCTV) camera technology with an automatic helmet use detection system and to identify the factors associated with helmet use along an urban arterial road in the city of Khon Kaen, Thailand. METHODS Data collection was carried out on 49,128 samples by video cameras installed at 5 signalized intersections during 2 periods, namely, before and during the CCTV camera enforcement. The study applied logistic regression analysis to determine factors associated with helmet use and to compare the ratio of helmet use for each variable according to the odds ratio. RESULTS The study found that CCTV camera enforcement could increase helmet usage at all study intersections by 5.3%. The results imply that 4 factors, including riding status, number of passengers, day of week, and traffic conditions, significantly affected helmet use both before and during the CCTV camera enforcement. Remarkably, 2 more variables, age and police inspection, significantly affected helmet use during the CCTV camera enforcement period. CONCLUSIONS This study confirms that CCTV camera enforcement can be an important driving force for changing helmet use behavior, particularly for child passengers. Moreover, CCTV camera enforcement can support enforcement by extending coverage to a 24-h period and to intersections without police inspection.

Abstract
BACKGROUND Bicycle injuries continue to cause significant morbidity in the United States. How insurance status affects outcomes in children with bicycle injuries has not been defined. We hypothesized that payer status would not impact injury patterns or outcomes in pediatric bicycle-related accidents. METHODS The National Trauma Data Bank was used to identify pediatric (≤18 y) patients involved in bicycle-related crashes admitted in year 2016. Patients with private insurance were compared with all others (uninsured, Medicaid, and Medicare). RESULTS There were 5619 patients that met study criteria. Of these, 2500 (44%) had private insurance. Privately insured were older (12 y versus 11, P < 0.001), more likely to be white (77% versus 56%, P < 0.001), and more likely to wear a helmet (26% versus 9%, P < 0.001). On multivariate analysis, factors associated with traumatic brain injury included age (odds ratio [OR], 1.07; 95% confidence interval [CI], 1.06-1.08; P < 0.001) and helmet use (OR, 0.64; 95% CI, 0.55-0.74; P < 0.001). Patients without private insurance were significantly less likely to wear a helmet (OR, 0.52; 95% CI, 0.44-0.63; P < 0.001). Uninsured patients had significantly higher odds of a fatal injury (OR, 4.43; 95% CI, 1.52-12.92; P = 0.006). CONCLUSIONS Uninsured children that present to a trauma center after a bicycle accident are more likely to die. Although helmet use reduced the odds of traumatic brain injury, minorities and children without private insurance were less likely to be helmeted. Public health interventions should increase helmet access to children without private insurance, especially uninsured children.

Abstract
BACKGROUND The objective of this study is to provide an up-to-date overview of the patterns of injuries, especially traumatic brain injury (TBI) caused by RTAs and to discuss some of the public health consequences. METHODS A scientific team was established to collect road traffic accidents occurring between 2013 and 2018 in Chongqing, Southwest China. For each accident, the environment-, vehicle-, and person- variables were analyzed and determined. The overall injury distribution and TBI patterns of four types of road users (driver, passenger, motorcyclist and pedestrian) were compared. The environmental and time distribution of accidents with TBI were shown by bar and pie chart. The risks of severe brain injury whether motorcyclist wearing helmets or not were compared and the risk factors of severe TBI in pedestrian were determined by odds ratio analysis. RESULTS This study enrolled 2131 accidents with 2741 persons of all kind of traffic participants, 1149 of them suffered AIS1+ head injury and 1598(58%) died in 7 days. The most common cause of deaths is due to head injury with 714(85%) and 1266(79%) persons died within 2 hours. Among 423 persons suffered both skull fracture and intracranial injury, 102 (24.1%) have an intracranial injury but no skull fractures, while none of the skull fractures without intracranial injury was found. Besides, motorcyclists without a helmet were at higher risks for all the brain injury categories. The risk of pedestrian suffering severe TBI at an impact speed of more than 70 km/h is 100 times higher than that with an impact speed of less than 40 km/h. CONCLUSION It is urgently needed to develop a more reliable brain injury evaluation criterion for better protection of the road users. We believe that strengthening the emergency care to head injury at the scene is the most effective way to reduce traffic fatality.

Abstract
INTRODUCTION Bicycles are a source of transportation, recreation, and exercise throughout the world. Bicycling is associated with both health and environmental benefits but also poses a risk of injury. The use of bicycle helmets has been shown to reduce morbidity and mortality associated with cycling. It is unknown if helmet use differs across Wisconsin geographic areas and sociodemographic groups. METHODS Data were obtained from the Survey of the Health of Wisconsin (SHOW). Bicycle use and helmet use frequency were determined from a self-administered questionnaire that contained questions specific to preventative health behaviors. Descriptive statistics summarized overall bicycle ridership. Chi-square and Student t tests were performed to assess relationships between bicycle and helmet use across geographic categories and sociodemographic groups. RESULTS Differences between sex, race or ethnicity, and education level were found to be associated with bicycle ridership and the frequency of helmet use. Men were significantly more likely to report riding a bicycle and never wearing a helmet. Individuals from urban communities reported always wearing a helmet more often than rural communities. Higher education levels were associated with higher levels of bicycle and helmet use. Race or ethnicity was not associated with bicycle ridership but was associated with differences in helmet use frequency. CONCLUSION Nearly half of those who ride bicycles in Wisconsin report never wearing a helmet. Since bicycle ridership and helmet use were found to be associated with a number of sociodemographic characteristics, any solution should consider the role of equity when attempting to increase ridership or helmet use.

Abstract
BACKGROUND The maxillofacial structures are commonly affected in motorcycle crashes, with the mandible being one of the most frequently fractured bones. Helmets have been shown to have a protective effect in preventing maxillofacial injuries, however, its effect on the occurrence of mandibular fractures is not very well established. OBJECTIVES To evaluate the pattern of mandibular fractures among motorcycle crash victims in Tanzania, and determine the role of helmets in occurrence of mandibular fractures among the motorcyclists. METHODOLOGY This was a 6-months prospective, cross-sectional study that recruited motorcycle crash victims who reported with mandibular fractures following motorcycle crash at Muhimbili National Hospital. A specially designed questionnaire was used for data collection. For purpose of analysis, the Statistical Package for Social Sciences software version 20 was used. RESULTS The study included a total of 132 participants of whom majority were male (120, 90.9%). The peak age incidence was 21-40 years in 76.5% of the victims. More than half (89, 67.4%) of the victims were riders during the crash. Helmet use was reported in 42.3% of the victims, and majority (67.3%) were usinghalf-face helmets. The symphysis region was the frequently fractured anatomical location (50, 37.9%). More than half of the victims had multiple site involvement, with higher odds observed in individuals wearing half-face helmets. CONCLUSION Young males were affected ten times more than females. Most of the victims were riders during the crash. The symphysis region was the frequently fractured anatomical site. There was no difference in occurrence of mandibular fractures between those who wore and those who did not wear helmets during the crashes. However, the severity of mandibular fractures was dependent on the type of helmet used.

Abstract
OBJECTIVE To observe the role of motorcycles in causing Road Traffic Accidents and assess the demographics of the drivers, the injury patterns and their outcomes. METHODS This prospective observational study was conducted at the Surgical Unit 1, Lahore General Hospital, Lahore for a period of 6 months from November 2017 to May 2018. All patients presenting in ER with RTA secondary to motorcycle trauma were included in the study. Data of patients including demographic and medical data, helmet use, spectrum of injuries, specific injury diagnosis, and final disposition of patients was analyzed. The distribution and associations of both victim- and crash-related variables such as crash mechanism, types of involved vehicles, types of injuries, and demographic characteristics were investigated. Data were analyzed by SPSS v23. RESULTS A total of 835 patients were included in this study with 685 (82%) being male (mean age 28.38 ± 13.89 years) and775 (92.7%) were motorcycle users. The majority of road traffic crashes, traffic accident's mechanism were motorcycle-vehicle accident 579 (69.3%), followed by collision with slow moving carts and bicycles 104 (12.5%). Inner city main roads were the site for 563 (67.4%) accidents. Only 168 (2.2%) patients were wearing helmets at the time of trauma. CONCLUSIONS Motorcycle traffic morbidities and mortalities remain to be a major public health issue in Lahore as well as all over Pakistan. There is an urgent need for an efficacious interventional programs to decline the burden of motorcycle related morbidity and mortalities.

Abstract
The continuous motorization of traffic has led to a sustained increase in the global number of road related fatalities and injuries. To counter this, governments are focusing on enforcing safe and law-abiding behavior in traffic. However, especially in developing countries where the motorcycle is the main form of transportation, there is a lack of comprehensive data on the safety-critical behavioral metric of motorcycle helmet use. This lack of data prohibits targeted enforcement and education campaigns which are crucial for injury prevention. Hence, we have developed an algorithm for the automated registration of motorcycle helmet usage from video data, using a deep learning approach. Based on 91,000 annotated frames of video data, collected at multiple observation sites in 7 cities across the country of Myanmar, we trained our algorithm to detect active motorcycles, the number and position of riders on the motorcycle, as well as their helmet use. An analysis of the algorithm's accuracy on an annotated test data set, and a comparison to available human-registered helmet use data reveals a high accuracy of our approach. Our algorithm registers motorcycle helmet use rates with an accuracy of -4.4% and +2.1% in comparison to a human observer, with minimal training for individual observation sites. Without observation site specific training, the accuracy of helmet use detection decreases slightly, depending on a number of factors. Our approach can be implemented in existing roadside traffic surveillance infrastructure and can facilitate targeted data-driven injury prevention campaigns with real-time speed. Implications of the proposed method, as well as measures that can further improve detection accuracy are discussed.

Abstract
INTRODUCTION Bicycle helmet use is recognized as an effective way to prevent head injuries in cyclists. A number of countries have introduced legislation to make helmets mandatory, but many object to this type of measure for fear that it could discourage people, particularly teenagers, from cycling. In 2011, the City of Sherbrooke adopted a bylaw requiring minors to wear a bicycle helmet. The objective of this study was to assess the impact of this bylaw on cycling and bicycle helmet use. METHODS The impact of the bylaw was measured by comparing the evolution of bicycle helmet use among youth aged 12 to 17 years in the Sherbrooke area (n = 248) and in three control regions (n = 767), through the use of logistic regression analyses. RESULTS Cycling rates remained stable in the Sherbrooke area (going from 49.9% to 53.8%) but decreased in the control regions (going from 59.1% to 46.3%). This difference in evolution shows that cycling rates increased in the Sherbrooke area after the adoption of the bylaw, compared to the control regions (odds ratio [OR] of the interaction term: 2.32; 95% confidence interval [CI]: 1.01-5.35). With respect to helmet use, a non-statistically significant upward trend was observed in the Sherbrooke area (going from 43.5% to 60.6%). This figure remained stable in the control regions (going from 41.5% to 41.9%). No significant difference was observed in the evolution of helmet use between the two groups (OR of the interaction term of 2.70; 95% CI: 0.67-10.83). CONCLUSION After the bylaw was adopted, bicycle use among youth aged 12 to 17 years in the Sherbrooke area remained stable and helmet used increased, though not significantly.

Abstract
Objective: Focusing on children (0-17 years), this study aimed to investigate injury and accident characteristics for bicyclists and to evaluate the use and protective effect of bicycle helmets.Method: This nationwide Swedish study included children who had visited an emergency care center due to injuries from a bicycle crash. In order to investigate the causes of bicycle crashes, data from 2014 to 2016 were analyzed thoroughly (n = 7967). The causes of the crashes were analyzed and categorized, focusing on 3 subgroups: children 0-6, 7-12, and 13-17 years of age. To assess helmet effectiveness, the induced exposure approach was applied using data from 2006 to 2016 (n = 24,623). In order to control for crash severity, only bicyclists who had sustained at least one Abbreviated Injury Scale (AIS) 2+ injury (moderate injury or more severe) in body regions other than the head were included.Results: In 82% of the cases the children were injured in a single-bicycle crash, and the proportion decreased with age (0-6: 91%, 7-12: 84%, 13-17: 77%). Of AIS 2+ injuries, 8% were head injuries and 85% were injuries to the extremities (73% upper extremities and 13% lower extremities). Helmet use was relatively high up to the age of 10 (90%), after which it dropped. Helmets were much less frequently used by teenagers (14%), especially girls. Consistently, the share of head injuries increased as the children got older. Bicycle helmets were found to reduce all head injuries by 61% (95% confidence interval [CI], 10: +/- 10%) and AIS 2+ head injuries by 68% (95% CI, 12: +/- 12%). The effectiveness in reducing face injuries was lower (45% CI +/- 10% for all injuries and 54% CI +/- 32% for AIS2+ injuries).Conclusions: This study indicated that bicycle helmets effectively reduce injuries to the head and face. The results thus point to the need for actions aimed at increasing helmet use, especially among teenagers. Protective measures are necessary to further reduce injuries, especially to the upper extremities.

Abstract
INTRODUCTION The evaluation of head protection systems needs proper knowledge of the head impact conditions in terms of impact speed and angle, as well as a realistic estimation of brain tolerance limits. In current bicycle helmet test procedures, both of these aspects should be improved. METHOD The present paper suggests a bicycle helmet evaluation methodology based on realistic impact conditions and consideration of tissue level brain injury risk, in addition to well known headform kinematic parameters. The method is then applied to a set of 32 existing helmets, leading to a total of 576 experimental impact tests followed by 576 numerical simulations of the brain response. RESULTS It is shown that the most critical impacts are the linear-lateral ones as well as the oblique impact leading to rotation around the vertical axis (ZRot), leading both to around 50% risks of moderate neurological injuries. Based on this test method, the study enables us to compare the protection capability of a given helmet and eventually to compare helmets via a dedicated rating system.

Abstract
Objective: Car drivers tend to underestimate the speed of e-bikes and accept smaller gaps for crossing in front of them compared to conventional bicycles. As an explanation, it has been suggested that car drivers rely on their previous experience with conventional bicycles, which tells them that those mostly travel at low speeds. E-bikes, which look just like regular bicycles, do not conform to this expectation, resulting in potentially dangerous interactions. Based on this assumption, researchers have suggested to increase other road users' awareness of e-bikes' higher speeds by giving them a distinct appearance. The goal of our experiment was to investigate the effects of such a unique appearance, aided by clear instructions about the higher speeds of e-bikes, on gap acceptance.Method: In order to investigate the effect of appearance independent of the effect of bicycle type, we used video sequences of conventional bicycles and e-bikes approaching at different levels of speed. The riders (regardless of what type of bike they were actually riding) either wore an orange helmet as an indicator for an e-bike, or a gray helmet indicating a conventional bicycle. Fifty participants were asked to indicate the smallest acceptable gap for a left turn in front of the cyclist or e-bike rider.Results: The results showed significantly smaller acceptable gaps when confronted with the gray helmet (signal for bicycle) compared to the orange helmet (signal for e-bike), whereas there was no difference between the actual bicycle types.Conclusions: Overall, the results indicate that informing about e-bikes characteristics in combination with a unique appearance can lead to a more cautious behavior among car drivers.

Abstract
Objectives: Motorcycle crashes are the second most common cause of road traffic injuries in Nigeria, which can be prevented through compliance with road safety measures. Compliance is defined as a state of being in accordance with established guidelines or legislations. There is a dearth of information on compliance with these measures by motorcyclists in Ibadan. Commercial motorcyclists often ignore safety measures, making them prone to accidents with other road users. This study therefore assessed the knowledge and reported compliance of commercial motorcyclists in Ibadan North Local Government Area with road safety measures as well as the factors influencing compliance.Data and methods: A cross-sectional study was carried out among motorcyclists in all 5 motorcycle parks in the city of Ibadan. Participants were selected through a simple random sampling technique after a proportional allocation to the size of the motorcyclists in the parks was concluded. A total of 439 motorcyclists were interviewed. A pretested, semistructured, interviewer-administered questionnaire was used to collect information on sociodemographic characteristics, knowledge, reported compliance, and attitudes toward road safety measures (Nigeria Highway Code). A total of 34 items on traffic rules and regulations were used to assess compliance. Chi-square test and logistic regression were used for analysis at a 5% level of significance.Result: Respondents were aged 34.4 ± 7.8 years. All respondents were male and 15.2% had a tertiary education in a university or institution of higher learning. About 20.0% had no proper formal or informal training as motorcyclists. Ninety-four respondents (21.6%) self-reported ever being involved in a motorcycle crash, of which 32 (34.0%) occurred 6 months preceding the study. About half of respondents (51.9%) had good knowledge of road safety measures. About 50.6% of the respondents were compliant with road safety measures. Only 54.4% of respondents who had ever been involved in a motorcycle crash were wearing a crash helmet at the time of the crash. However, 71.8% of respondents had a crash helmet with them during the study. About 73.6% owned the motorcycles they rode. About two thirds (60.4%) of motorcycle owners were significantly more compliant compared to 23.3% of those who were not owners. Respondents who were motorcycle owners were almost 4 times more likely to be compliant with road safety measures than those who were not owners (odds ratio [OR] = 4.0; confidence interval [CI], 2.0-7).Conclusion: Commercial motorcycle ownership and training contributed to knowledge and compliance with road safety measures and consequently low reporting of motorcycle crash. There is therefore the need to encourage ownership, conduct training, and create stringent laws to guide road safety.

Abstract
Commercial motorcycle (CM) accidents constitute a major public concern in Nigeria. There is 8:10 chance that injuries resulting from these accidents are severe and debilitating including head and spinal injuries. This study is aimed at producing useful data on the prevalence, frequency, and determinants of helmet use among commercial motorcyclist in Ido-Osi Local Government Area, Ekiti State, Nigeria. The study was a descriptive/cross-sectional study. A total of 360 respondents were selected by multi-stage sampling technique and interviewed using assisted self-administered, semi-structured questionnaire. Data were analyzed using SPSS version 21. Determinants of helmet use examined included age, educational level, marital status and religion. There was a 100% response rate. More than half of the respondents were within the age range of 20-29 years 164(53.6%) with the mean age of the study participants 29.9. The prevalence of helmet usage among commercial motorcyclist was 23.5%. The commonest reason for not using a crash helmet in this study was non-availability. The commonest reason for the non-availability of the welding helmet was the cost of the helmet. Less than half of the respondents were able to show or present helmet although some of the helmet presented were sub-standard (39.7%). The study also revealed irregular use of helmets among the respondents that used a helmet while riding a motorcycle as only 2.7% of them used it for all the five riding sessions assessed in this study. There was a statistically significant relationship between age, educational level, marital status and the use of helmets among respondents with p values of 0.005, 0.027, and 0.009, respectively. The prevalence of the use of helmets among the motorcyclist in this study is low despite the high level of awareness of legislation among the respondents on the use of helmets during riding. There is a need for the government to make provision for a safety helmet for this group of people at a subsidized rate if it cannot be given free of charge because of the economic situation of the country. There is a need to carry out behavioral change communication for this group of people.

Abstract
Objective: According to the United Nations, nearly 1.25 million people are killed and up to 50 million people are injured on the world's roads every year. Uganda loses about 10 people daily to road accidents, costing about US$1.2 billion annually, which represents about 5% of the gross domestic product (GDP). The objective of this study was to identify causal factors that can be associated with boda-boda accidents in Uganda.Method: A cross sectional study assessed 200 boda-boda riders in the urban areas of Kampala, Uganda. Interviews using semistructured questionnaires were administered to all participants. Data were entered in Excel and imported to STATA for analysis. Multivariate and bivariate analyses were conducted to determine factors that influenced accident risk perception. All variables that were significant at a bivariate level and thought to be theoretically important in influencing the outcome variable were included in a logistic regression model. All tests were performed at a significance of P < .05.Results: Competition for passengers with other public transport operators (83%), negligence of road safety rules (78%), and inadequate helmet usage (62%) were the main factors perceived to be associated with boda-boda accidents. Other factors identified by the respondents include age of the boda-boda rider (58%) and drug use (56%; P < .05). At multivariate analysis, competition for passengers (adjusted odds ratio [AOR] = 17; 95% confidence interval CI, 1.34-26.5) and being in between 18 and 25 years old (AOR = 19; 95% CI, 1.42-27.1) remained statistically significant.Conclusions: This study revealed behavioral factors by all public transport users as the main factors associated with boda-boda accidents in urban Kampala. This demonstrates the need for holistic interventions to address such boda-boda accidents in Uganda. Such interventions can be through digitization of transport system for clients to engage remotely with the transport operators, routine refresher trainings of all transport operators, and construction of lanes for boda-boda riders.

Abstract
Motorcycle and moped injuries remain a significant cause of motor-vehicle related morbidity and mortality. There is a paucity of literature describing the skeletal injuries of moped riders and how these compare to those of motorcyclists, however. This study seeks to examine the skeletal injuries sustained in such incidents and determine if there are significant differences. Hospitalized riders injured on powered two-wheeled vehicles (PTW) between 2004 and 2007 were entered into a registry along with their presentation and clinical course. This registry was sorted by PTW type. Riders with injuries of the appendicular skeleton, bony pelvis, and spine were extracted. Injuries were categorized by bone location. Demographic data, helmet use, head injury, facial fracture, Injury Severity Score (ISS), and mortality were extracted. Overall, 406/578 motorcyclists, 197/357 moped riders, and 62/92 dirt-bike riders sustained fractures of the appendicular skeleton, pelvis and/or spine. Motorcyclists had a significantly higher ISS upon presentation and had increased first-hospital day mortality in addition to more skeletal injuries, more fractures of the upper extremity, and more fractures of the spine, pelvis, and foot. Moped riders had a significantly lower rate of helmet use and higher rate of head injuries and facial fractures. In summary, while both moped and motorcycle riders share a risk for injuries of the lower extremity, their overall pattern of injury differs. Motorcyclists appear to be at increased risk for more severe injuries and injuries of the upper extremity, spine, and pelvis, while moped riders are at increased risk for significant head and facial injury.

Abstract
Shared-bicycle use has skyrocketed in urban China, but little is known about the safety of bicycle users. The Chinese popular media reports multiple risky riding behaviors among shared bicycle riders, but scientific research on the topic is lacking. Therefore, we conducted a retrospective WeChat-based online survey to examine how often shared bicycle riders report engaging in risky cycling behaviors in urban China. Eight unsafe shared bicycle riding behaviors were assessed: not wearing helmets, running red lights, cycling against the traffic flow, riding in lanes designed for motor vehicles, riding in lanes designed for pedestrians, carrying passengers on bicycles, using cell phones while riding, and eating while riding. In total, 1960 valid questionnaires were collected. The proportion of participants who reported always or often having unsafe riding behavior in the past month, ranged from 1.1% for carrying passengers on the bicycles to 97.6% for failing to wear a helmet. Demographic characteristics were associated with unsafe behaviors through multivariate logistic regression, with male riders and riders aged 25 years or younger more likely to ride while using cell phones than females (AOR = 2.94) and those 36 years or older (AOR = 3.57). Cyclists with undergraduate education were more likely to wear helmets than those with postgraduate education or higher (AOR = 0.21). Compared to riders from central municipalities governed directly by the central government, riders from provincial capitals, deputy provincial cities, and smaller cities were at higher risks of riding in lanes for pedestrians, respectively (AOR = 1.59, 2.82 and 1.61). Riders who rode over 5 h a week and who rode on weekends were more likely to carry passengers than those who rode less than 1 h a week (AOR = 4.72) and those who rode only on weekdays (AOR = 3.93). We conclude that shared-bicycle riders frequently engage in some unsafe riding behaviors in urban China. Younger age, lower level of education, and longer hours of riding each week are associated with greater risks of some unsafe riding behaviors. Shared bicycles offer substantial benefit to societal health and transportation, but evidence-based interventions should be considered to reduce risks from unsafe shared bicycle riding behaviors. A well-designed road infrastructure with dedicated on-road bicycle lanes and readily-accessible comfortable, low-cost, and safe helmets may also reduce unsafe riding behaviors and unwanted crashes and injuries for shared bicycle riders.

Abstract
Motorcyclists are vulnerable road users at a particularly high risk of serious injury or death when involved in a crash. In order to evaluate key risk factors in motorcycle crashes, this study quantifies how different "policy-sensitive" factors correlate with injury severity, while controlling for rider and crash specific factors as well as other observed/unobserved factors. The study analyzes data from 321 motorcycle injury crashes from a comprehensive US DOT FHWA's Motorcycle Crash Causation Study (MCCS). These were all non-fatal injury crashes that are representative of the vast majority (82%) of motorcycle crashes. An anatomical injury severity scoring system, termed as Injury Severity Score (ISS), is analyzed providing an overall score by accounting for the possibility of multiple injuries to different body parts of a rider. An ISS ranges from 1 to 75, averaging at 10.32 for this sample (above 9 is considered serious injury), with a spike at 1 (very minor injury). Preliminary cross-tabulation analysis mapped ISS to the Abbreviated Injury Scale (AIS) injury classification and examined the strength of associations between the two. While the study finds a strong correlation between AIS and ISS classification (Kendall's tau of 0.911), significant contrasts are observed in that, when compared to ISS, AIS tends to underestimate the severity of an injury sustained by a rider. For modeling, fixed and random parameter Tobit modeling frameworks were used in a corner-solution setting to account for the left-tail spike in the distribution of ISS and to account for unobserved heterogeneity. The developed random parameters Tobit framework additionally accounts for the interactive effects of key risk factors, allowing for possible correlations among random parameters. A correlated random parameter Tobit model significantly out-performed the uncorrelated random parameter Tobit and fixed parameter Tobit models. While controlling for various other factors, we found that motorcycle-specific shoes and retroreflective upper body clothing correlate with lower ISS on-average by 5.94 and 1.88 units respectively. Riders with only partial helmet coverage on-average sustained more severe injuries, whereas, riders with acceptable helmet fit had lower ISS Methodologically, not only do the individual effects of several key risk factors vary significantly across observations in the form of random parameters, but the interactions between unobserved factors characterizing random parameters significantly influence the injury severity score as well. The implications of the findings are discussed.

Abstract
INTRODUCTION Efforts to encourage bicycling to school have increased in the United States. However, little is known about how parent-child communication affects bicycle safety. The purpose of this study was to examine parent-child agreement on biking instructions and their correlation with the early adolescents' real-world riding behavior. METHODS Parent-child dyads were asked open-ended questions about instructions they had given/received about bicycling. Answers were then coded into nine categories (e.g., crossing the road, bicycle control/handling). Distributions of parent-child agreement on parent-given bicycle safety instructions were examined in relation to the adolescent's real-world riding behaviors. RESULTS 36 parent-child dyads were included. Average age was 11.9 (Range: 10-15) for adolescents and 43.3 (Range: 30-59) for parents. Common parental instructions included: wear helmet, ride on sidewalk, and trip routing specifications. High 'ride on sidewalk' instruction (38.9% both parent and adolescent, 22.2% parent only, 16.7% adolescent only) was concerning due to potential driveway conflicts. Agreement between parents and adolescents on reported instructions was low, overall. Mean safety-relevant event rates in real-world cycling did not differ significantly between bicycle safety instruction agreement groups (both parent & adolescent reported, parent only, adolescent only, neither). The proportion of time an adolescent rode on different infrastructure types (sidewalk, street, etc.) did not vary between dyads reporting parents had given instructions to ride on the sidewalk and those who had not. CONCLUSIONS Results highlight lack of agreement between parents and adolescents on cycling instructions the adolescent receives from the parent. Parent instructions to adolescents regarding bicycling safety were not associated with actual riding behaviors. Results suggest parent messaging to adolescents may be ineffective. Given parents are in a position of influence, results indicate a need for parental training on effective safety-related communication strategies to assist them in capitalizing on their parental role to increase their child's safety.

Abstract
AIM To assess the attitudes of mountain bikers to the use of protective equipment and quantify the use of such equipment. METHOD This was a prospective cohort study using an online questionnaire, offered to bikers participating in a series of Enduro races. The attitudes towards various factors that might contribute to a rider's choice to use protective equipment were quantified based on their responses to the questions. The actual reported use of various types of protective equipment was the outcome measure. The correlations between the factors and actual use were analysed for statistical significance, to assess their relative importance. RESULTS Equipment use was similar in racing and non-racing settings and could be increased. 55% had experienced an injury requiring a week or more off work. Perceptions of the benefits, costs, cues, comfort and potential injury severity proved to be well correlated with the choice to use equipment, while harm, danger and exposure to media influences did not.

Abstract
OBJECTIVES In the last 10 years there has been a significant increase in cycle traffic in the UK, with an associated increase in the overall number of cycling injuries. Despite this, and the significant media, political and public health debate into this issue, there remains an absence of studies from the UK assessing the impact of helmet use on rates of serious injury presenting to the National Health Service (NHS) in cyclists. SETTING The NHS England Trauma Audit and Research Network (TARN) Database was interrogated to identify all adult (≥16 years) patients presenting to hospital with cycling-related major injuries, during a period from 14 March 2012 to 30 September 2017 (the last date for which a validated dataset was available). PARTICIPANTS 11 patients met inclusion criteria. Data on the use of cycling helmets were available in 6621 patients. OUTCOME MEASURES TARN injury descriptors were used to compare patterns of injury, care and mortality in helmeted versus non-helmeted cohorts. RESULTS Data on cycle helmet use were available for 6621 of the 11 192 cycle-related injuries entered onto the TARN Database in the 66 months of this study (93 excluded as not pedal cyclists). There was a significantly higher crude 30-day mortality in un-helmeted cyclists 5.6% (4.8%-6.6%) versus helmeted cyclists 1.8% (1.4%-2.2%) (p<0.001). Cycle helmet use was also associated with a reduction in severe traumatic brain injury (TBI) 19.1% (780, 18.0%-20.4%) versus 47.6% (1211, 45.6%-49.5%) (p<0.001), intensive care unit requirement 19.6% (797, 18.4%-20.8%) versus 27.1% (691, 25.4%-28.9%) (p<0.001) and neurosurgical intervention 2.5% (103, 2.1%-3.1%) versus 8.5% (217, 7.5%-9.7%) (p<0.001). There was a statistically significant increase in chest, spinal, upper and lower limb injury in the helmeted group in comparison to the un-helmeted group (all p<0.001), though in a subsequent analysis of these anatomical injury patterns, those cyclists wearing helmets were still found to have lower rates of TBI. In reviewing TARN injury codes for specific TBI and facial injuries, there was a highly significant decrease in rates of impact injury between cyclists wearing helmets and those not. CONCLUSIONS This study suggests that there is a significant correlation between use of cycle helmets and reduction in adjusted mortality and morbidity associated with TBI and facial injury.

Abstract
According to the risk compensation hypothesis, the use of a ski helmet might provide a false sense of security, resulting in a riskier behavior by skiing faster or more aggressively, which might lead to an increased injury risk. Injury of the anterior cruciate ligament (ACL) is a common diagnosis in downhill skiers. Thus, the aim of the study was to evaluate the potential impact of risk-taking and ski helmet use on ACL injury risk in recreational skiing. Eighty-two ACL injured and 446 uninjured skiers with a mean age of 37.3 ± 11.9 years (52% females) were surveyed during the winter season 2018/19 about age, sex, self-reported risk-taking behavior, self-reported skill level, perceived speed, and ski helmet use. Multiple regression analysis revealed that older age (OR: 1.3, 95% CI: 1.2–1.4), riskier behavior (OR: 5.4, 95% CI: 2.8–10.5), and lower skill level (OR: 6.7, 95% CI: 3.4–13.3) were found to be factors associated with ACL injury, while ski helmet use was not. In conclusion, no support for the risk compensation hypothesis was found with regard to ACL injuries. Therefore, we doubt that ski helmet use increases the risk for ACL injury and recommend wearing a ski helmet due to reported protective effects.

Abstract
OBJECTIVE To quantify the magnitude of associations between cyclist fatalities and both cyclist and environment related characteristics in Spain during the first 24 hours after a crash. DESIGN Cohort study. SETTING Spain. PARTICIPANTS 65 977 cyclists injured in road crashes recorded between 1993 and 2013 in the Spanish Register of Road Crashes with Victims. MAIN OUTCOME Death within the first 24 hours after the crash. METHODS A multiple imputation procedure was used to mitigate the effect of missing values. Differences between regions were assumed and managed with multilevel analysis at the cyclist and province levels. Incidence density ratios (IDR) with 95% CI were calculated with a multivariate Poisson model. RESULTS Non-use of a helmet was directly associated with death (IDR 1.43, 95% CI 1.25 to 1.64). Among other cyclist characteristics, age after the third decade of life was also directly associated with death, especially in older cyclists ('over 74' category, IDR 4.61, 95% CI 3.49 to 6.08). The association with death did not differ between work-related cycling and other reasons for cycling.There was an inverse association with death for crashes in urban areas and on community roads. Any adverse meteorological condition also showed a direct association with death, whereas altered road surfaces showed an inverse association. Crashes during nighttime were directly associated with death, with a peak between 3:00 and 5:59 am (IDR 1.58, 95% CI 1.03 to 2.41). CONCLUSIONS We found strong direct and inverse associations between several cyclist and environment related variables and death. These variables should be considered in efforts to prioritise public health measures aimed at reducing the number of cycling-related fatalities.

Abstract
Objective: Road traffic accidents (RTAs) are the number one cause of traumatic brain injuries (TBIs) worldwide. This study examines RTA-related TBIs in the Dominican Republic, a country in the Caribbean with the highest RTA fatality rate in the Western Hemisphere. Methods: We interviewed 117 adult patients or medical guardians of patients admitted to Hospital Traumatológico Dr. Ney Arias Lora in Santo Domingo following an RTA. Information regarding the type of accident, patient demographics, and injuries sustained was collected for each patient. Results: Most study participants were males (79.5%), and the most common method of transportation was motorized 2-wheeled vehicle (MTW; 74.4%). Of the 69 patients who suffered a TBI, 66.7% were classified as moderate-severe TBIs and 30.3% were classified as mild TBIs. The most common types of intracranial hemorrhage were subdural hemorrhage (12%) and subarachnoid hemorrhage (9.4%). Helmet use among admitted MTW riders was reported at 22.4%, and none of the 9 MTW riders who died in the hospital were wearing a helmet. Only 58.1% of patients lived in an area that offered 911 emergency response services at the time of the study. At 66.2%, the majority of people living within the 911 service area utilized emergency response services following an RTA. Multiple logistic regression determined that the utilization of 911 emergency response services was associated with a decrease in the likelihood of presenting with a moderate/severe TBI by a factor of 0.78 (adjusted odds ratio [OR]; P < .008; 95% confidence interval [CI], 0.65, 0.93). Nonuse of a helmet was associated with a 1.22 times increased risk of presenting with a moderate/severe TBI (adjusted OR; P < .04; 95% CI, 1.01, 1.61). Age and gender were not statistically significant in this model. Conclusions: The results of this study support 2 important avenues for reducing the burden of RTA-associated neurologic disease in the Dominican Republic. As with many other middle-income countries, MTWs represent an economical and efficient mode of transportation. Therefore, increasing helmet use may be the most effective way to reduce RTA-associated TBIs. In addition, continuing the expansion of postcrash emergency response services may mitigate the severity of RTA-associated neurologic disease.

Abstract
Wearing a helmet when bicycling prevents traumatic brain injury in the event of a crash. Most cyclists nationwide use helmets when riding. However, the growth of free-floating bike sharing systems, which offer short-term access to bicycles but not helmets, may erode helmet-wearing norms among cyclists. We counted cyclists over several hours at four locations in Seattle, WA. We categorized each rider according to whether he or she was wearing a helmet and to whether or not he or she was riding a bike share bike. Whereas 91% of riders of private bikes wore helmets, only 20% of bike share riders wore helmets. Moreover, in locations where a greater proportion of riders were on bikes hare bikes, fewer riders of private bicycles wore helmets (r = - 0.96, p = 0.04). The impact of bike sharing programs on helmet wearing norms among private bike riders warrants further exploration.

Abstract
Objective: The objective of this study was to analyze the association between consumption of alcoholic drinks and adoption of other risky forms of behavior in traffic among motorcyclists involved in accidents. Methods: This was an exploratory cross-sectional study among injured motorcyclists who were hospitalized in the traumatology department of the "Governador Paulo Guerra" Restoration Hospital (Hospital da Restauração Governador Paulo Guerra), Recife, Pernambuco, Brazil. A questionnaire containing items relating to sociodemographic, occupational, and behavioral factors and aspects of the accident and road conditions was applied. Descriptive and bivariate analyses were performed and odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. The significance level was set at 5%. Results: One hundred seventy individuals were investigated. Consumption of alcohol prior to the accident was reported by 32.9% of motorcyclists. This behavior was positively associated with the following risky forms of behavior in traffic: speeding (OR = 4.08; 95% CI, 1.15-9.48); failure to use a helmet (OR = 2.41; 95% CI, 1.15-5.02); and not having a motorcycle driver's license (OR = 2.68; 95% CI, 1.31-5.45). Conclusion: This study showed that, in the population studied, riding a motorcycle under the effects of alcoholic drinks was associated with other risky forms of behavior in traffic: speeding, not using a helmet, and not having a motorcycle driver's license. We believe that the interaction between these behaviors may lead to greater occurrence and greater severity of accidents.
