Alcohol-attributable deaths in Thai people from 2015 to 2021 using the comparative risk assessment approach.

The alcohol-attributable mortality rate is an important health indicator for surveillance of health-related impacts of alcohol consumption. This study aimed to estimate the annual number and rate of alcohol-attributable deaths among the Thai population aged 15 years and over during 2015-2021. Mortality data were drawn from the National Death Registry based on ICD-10. We used the standard methodology of comparative risk assessments for alcohol within the general framework of the Global Burden of Disease Studies and used alcohol-attributable fractions, derived from exposure, and relative risk compared to lifetime abstainers as the counterfactual. Age-standardization was used to adjust mortality rates which were calculated by cause, age group, and sex. The estimated annual number of alcohol-attributable deaths was 20,039 (men: 17,726 [6.50% of total annual deaths of the Thai population] and women: 2312 [1.11%]). The age-standardized alcohol-attributable mortality rates continuously increased from 33.8 to 37.5 deaths per 100,000 population from 2015 to 2019 and slightly decreased to 34.5 and 35.3 in 2020 and 2021, respectively. The three leading causes of death attributed to alcohol consumption were road injuries, cirrhosis and other liver diseases, and other unintentional injuries. Alcohol remains an important preventable cause of death among Thais. The alcohol-attributable mortality rate increased from 2015 to 2019 but declined in 2020 and 2021, possibly due to the coronavirus pandemic and lockdown measures. Culturally appropriate, cost-effective interventions should be used to control alcohol accessibility, particularly among young people who frequently sustain injuries from external causes and have high mortality rates.

Extreme heat and heatwaves are linked to the risk of unintentional child injuries in Guangzhou city

With unintentional injuries being the leading mortality cause among children, the comprehensive evaluation of the unintentional injury burden concerning heat exposure remains unknown. Here we quantified the years lived with disability (YLD) due to unintentional child injuries in Guangzhou from 2016–2020 using the injury surveillance data. A Poisson regression model was employed to explore how various magnitudes of heat exposure could increase the injury burden in different children’s subgroups. Our findings suggest a positive link between heat exposure and childhood injuries. The successive heatwave led to a 16.8–23.8% higher risk of childhood injuries. Girls and preschoolers exhibited higher vulnerability to heat. Furthermore, heat exposure increased the road injury burden for preschoolers aged 3–6 years but not for adolescents. Our study links heat exposure to childhood unintentional injuries, providing insights into the demographic features and injury causes. This evidence can be used to inform healthy childhood development.

ProtAct-Us from serious injuries with long-term consequences

Abstract Battling serious injuries and long-term consequences in road traffic remains one important issue in the overall goal of resilient future road transport and its Vision Zero. Challenges of increasing personal transport in urban areas coupled with autonomous vehicles and shuttles, new mobility devices and the overall need to ensure the safety of vulnerable road users as well as all types of vehicle occupants’ require solid medical background knowledge paired with innovative engineering approaches. EU Horizon Europe is currently funding the ProtAct-Us consortium (2024-2027) that aims at protecting all Road User Groups from serious injury and long-term physical, cognitive and mental health consequences related to road crashes through innovatively interlinked research action between medical and engineering methods and approaches. ProtAct-Us works on the following goals and challenges: i) Medical data correlation, standardisation and classification of long-term consequences of road crashes; ii) Robust and reliable medical, epidemiological and engineering tools like agreed methods to collect information on long-term consequences, upgraded Human Body Models and virtual assessment methods for the extremities, head, neck and face allowing for effective countermeasure development for all road users; iii) Reduction of long-term consequences and related socio-economic cost of road crash related injuries for all road users. The ProtAct-Us solutions will influence new standards in respect of extending current injury codification system with relevant long-term aspects, allowing new physical as well as virtual safety assessment procedures and adaption of rules and regulations to be implemented. Finally, scientifically well-founded suggestion for future implementation into policy, regulatory, and standardization guidelines for an inclusive safety improvement approach for in- as well as post-crash will be provided.

Fatal road traffic accidents and injuries: a preliminary study.

Road traffic accidents (RTAs) are a major public health problem globally and cause deaths, disability, and significant economic costs. In Italy, there was an increased number of road accidents, deaths, and injuries in 2022 compared to 2021, although still below pre-pandemic levels. A retrospective observational study was performed on a case series of 53 consecutive fatal RTAs examined by the Section of Forensic Medicine of Verona. The case series was divided, according to the type of victims involved, into pedestrians, car drivers, car passengers, and motorcyclists. For each, the times and causes of death, the distribution of external and internal injuries, and toxicological data were analysed, and the results were compared with those in the literature. Although this is a preliminary study on a small case series and lacks statistical validation, so more cases are needed, the preliminary results seem to provide a useful tool for assessing injuries in complex fatal road accidents.

Causes and predictors of premature death in the pars cohort study, Iran: a cohort study

BackgroundWhile death in old age is inevitable, premature death at younger ages is within our control. Premature mortality (death < 70 years) is a crucial indicator of health status and access to healthcare, with variations observed across regions. In North Africa and the Middle East, ischemic heart disease (IHD), road injuries, stroke, and chronic kidney disease are projected to be the main causes of premature mortality. Unfortunately, few studies have been conducted on premature mortality worldwide. This study aimed to analyze the causes of premature death and associated risk factors within the Pars Cohort Study.MethodsThe Pars Cohort Study is a prospective cohort study conducted in Fars Province, Iran, involving 9,264 individuals aged 40–75 years, 53.8% of whom were women. We assessed participants from baseline (2012–2014) to 2021. The data were gathered through interviews, biological samples, and physical examinations. The causes of premature mortality, hazard ratios (HRs), and population attributable fraction (PAF) with 95% confidence intervals (95% CIs) for the variables were calculated.ResultsOut of 388 deaths, 54% were premature. The most common causes of premature death included IHD (40%), stroke (11%), road traffic injuries (6%), lower respiratory infections (5%), and COVID-19 (3%). The predictive factors [adjusted HRs (95% CIs)] associated with premature mortality included age [year, 1.07 (1.04, 1.10)], tobacco [1.43 (0.96, 2.11)], opium [2.12 (1.39, 3.24)], hypertension [1.52 (1.10, 2.12)], waist circumference [cm, 1.03 (1.00, 1.05)], female sex [0.30 (0.19, 0.47)], education [> 8 years vs. no formal schooling, 0.46 (0.24, 0.88)], being married [0.60 (0.37, 0.97)], physical activity [3rd vs. 1st tertile, 0.38 (0.26, 0.57)], hip circumference [cm, 0.96 (0.92, 0.99)], estimated GFR [mL/min/1.73 m², 0.99 (0.978, 0.999)], and wealth score [4th vs. 1st quartile, 0.54 (0.32, 0.90)]. The PAF (95% CI) for all modifiable predictors was 0.83 (0.62, 0.92).ConclusionsThe predominant causes of premature mortality were IHD and stroke. To mitigate premature deaths, it is recommended to address both socioeconomic and behavioral factors simultaneously.

Friction Burns: Defining the Rub of Road Rash After Motorcycle Trauma.

There is a paucity of literature on friction burn epidemiology, injury characteristics, and management after trauma. This study aims to characterize friction burns resulting from motorcycle accidents, evaluate the role of specialized burn surgery teams, and assess the need for operative intervention. The trauma registry of a Level 1 Trauma Center was queried for all admissions after motorcycle accidents between January 2018 and December 2022. Patients were included if there was an external cause of injury code for an abrasion. Chart review was conducted to confirm a road rash injury, identify burn consultation, wound care recommendations, need for operating room (OR) procedure and skin grafting, and outcomes. Among the 810 patients meeting inclusion criteria, the cohort was 92% male, 46% Hispanic, with median age of 33 (IQR 26-44), and median ISS 8 (IQR 5-14). The extremities were most affected by friction burn followed by the abdomen, thorax, and face. Burn surgery was consulted in 7% (n=57) of cases which had a median TBSA of 4% (IQR 2-6%); 23% (n=13) of these patients underwent excision in the OR, 16% (n=9) required autografting, and 61% (n=35) were referred for burn follow-up on discharge. On multivariable regression, consults to burn were more likely in female patients (OR 3.40, p=0.002) and those with involvement of the upper extremity, abdomen, or thorax. Friction burns are common after motorcycle-related trauma. Local wound care is sufficient for a vast majority of these injuries and the need for specialized burn care and operative intervention is rare.

Insights into epidemiological trends of severe chest injuries: an analysis of age, period, and cohort from 1990 to 2019 using the Global Burden of Disease study 2019

BackgroundThis study assessed the global trends and burden of severe chest injury, including rib fractures, lung contusions, and heart injuries from 1990 to 2019. Herein, we predicted the burden patterns and temporal trends of severe chest injuries to provide epidemiological evidence globally and in China.MethodsIn our analysis, the age-standardized incidence rate (ASIR), prevalence rate (ASPR), and years lived with disability rate (ASYR) of severe chest injury were analyzed by gender, age, sociodemographic index, and geographical region between 1990 and 2019 using data from the Global Burden of Disease study 2019. Trends were depicted by calculating the estimated annual percentage changes (EAPCs). The impact of age, period, and cohort factors was assessed using an Age-Period-Cohort model. Autoregressive integrated moving average (ARIMA) model was employed to predict severe chest injury trends from 2020 to 2050.ResultsIn 2019, the global number of severe chest injury cases reached 7.95 million, with the highest incidence rate observed in Central Europe (209.61). Afghanistan had the highest ASIRs at 277.52, while North Korea had the lowest ASIRs at 41.02. From 1990 to 2019, the Syrian Arab Republic saw significant increases in ASIR, ASPR, and ASYR, with EAPCs of 10.4%, 9.31%, and 10.3%, respectively. Burundi experienced a decrease in ASIR with an EAPC of − 6.85% (95% confidence interval [CI] − 11.11, − 2.37), while Liberia’s ASPR and ASYR declined with EAPCs of − 3.22% (95% CI − 4.73, − 1.69) and − 5.67% (95% CI − 8.00, − 3.28), respectively. Falls and road injuries remained the most common causes. The relative risk of severe chest injury by age, period, and cohort demonstrated a complex effect globally and in China. The ARIMA model forecasted a steady increase in global numbers from 2020 to 2050, while in China, it forecasted an increase in incidence, a decrease in ASIR and ASYR, and an increase in ASPR.ConclusionsThis study provides a groundbreaking analysis of global severe chest injury, shedding light on its measures and impact. These findings highlight the need for timely, specialized care and addressing regional disparities to mitigate the severe chest injury burden.

A comparison of heat effects on road injury frequency between active travelers and motorized transportation users in six tropical and subtropical cities in Taiwan

Road traffic injuries (RTIs) pose significant public health threats, particularly for vulnerable road users such as pedestrians and cyclists. While recent studies have revealed adverse impacts of heat exposure on RTI frequency among motorized road users, a research gap persists in understanding these impacts on non-motorized road users, especially in tropical regions where their vulnerability can be heightened due to differential thermal exposure, adaptive capacity, and biological sensitivity. In this study, we compared associations between high temperatures and RTIs across four different crash-involved modes of transportation—pedestrians, cyclists, motorcyclists, and car drivers in Taiwan. Leveraging data on RTI records and temperature conditions in Taiwan's six municipalities from 2018 to 2022, we conducted a city-time-stratified case-crossover analysis. We employed distributed lag non-linear models with conditional Poisson regression models to estimate temperature-RTI associations for each mode of transportation, adjusting for various weather factors and unmeasured spatio-temporal patterns. Our findings reveal that individuals using exposed, open transportation modes (i.e., pedestrians, cyclists, and motorcyclists) exhibited higher relative risks of heat-induced RTIs than car drivers, with non-motorized mode users showing greater susceptibility compared to their motorized counterparts. These elevated risks can be attributed to the absence of built-in cooling systems in open travel modes and the increased exertional heat stress implied in active travel. Our study contributes novel insights to a global concern related to climate change, extending its impact to road safety, a health outcome rarely studied in the context of a changing climate. Our findings are thus important, especially for regions where rising temperatures regularly approach or exceed human physiological limits related to heat tolerance in the coming decades. Additionally, our findings hold significance in the existing urban health literature, particularly within the context of the emerging era of micromobility—a category of low-speed, non-enclosed, and lightweight vehicles increasingly integrated into urban activities worldwide.

Epidemiological Aspects of Road Accidents in the Middle East and North Africa (MENA) Countries from 1990 to 2019

Background: Road accidents are a major public health concern globally and are expected to become the fifth leading cause of death worldwide by 2030. Objectives: This study aimed to compare the consequences of road accidents in the Middle East and North Africa (MENA) region by analyzing data from 21 countries and approximately 400 million people Methods: The data used was from the Global Burden of Diseases (GBD) in 2019, which defines traffic accidents as deaths resulting from external injury causes based on the international classification of diseases (ICD). Results: Road traffic injuries (RTIs) in the MENA region have decreased from 1990 to 2019. Motor vehicles have the highest death rate from RTIs at 15.32 per 100,000, followed by pedestrians at 8.37 per 100,000, motorcyclists at 2.16 per 100,000, and cyclists at 0.35 per 100,000. Saudi Arabia (46.7 per 100,000) and Oman (25.5 per 100,000) have the highest death rates for motor vehicle-related road injuries, while Oman (17.7 per 100,000) and Yemen (12.95 per 100,000) have the highest rates for pedestrian-related road injuries. Conclusions: Given the significant impact of road accidents in the countries of the region, it is crucial to address this issue through various measures. These should include training initiatives, preventive measures, and a review of traffic laws and regulations.

Pedestrian behavior among Chinese seniors: Insights from factor analysis and structural equation modeling

Pedestrians contribute significantly to the total number of road fatalities and injuries, with their behavior playing a pivotal role in traffic mishaps. Despite this, a limited body of research has delved into the walking behaviors of Chinese seniors. Given this gap, our study rigorously examines the patterns of seniors’ walking behaviors and their influencing factors. We employed exploratory factor analysis to decipher the intrinsic component structures of seniors' walking patterns in China. Subsequently, structural equation modeling was utilized to analyze the impact of demographic attributes and personality characteristics on these behaviors. The findings revealed a four-dimensional structure for senior walking behaviors: transgression, inattention, aggression, and positive behaviors. Introducing personality traits as variables notably enhanced the explanatory power of our model. Specifically, anger, altruism, and normlessness significantly influenced certain dimensions of walking behaviors, while sensation-seeking did not exhibit any notable effect. This study not only highlights the complexity and diversity of elderly walking behaviors but also underscores the importance of tailored interventions to improve walking safety and quality of life for seniors.

Is Active Mobility Really a Sustainable Way of Travelling in Italian Cities? When and Where Injury Risk Offsets the Benefits of Riding or Walking

Even though active mobility is considered a sustainable way of travelling in urban environments, this might not always be the case because of a lack of infrastructure and poor road safety standards. This study assesses, under an economic point of view, the health benefits of a shift from private cars to active mobility for urban travels in Italy, considering both mortality and morbidity effects. The overall health effect is the result of positive (increased physical activity) and negative effects (increased air pollutant intake and increased road injury risk). Health impacts are measured using disability-adjusted life years and translated into monetary terms using either the value of a life year or the value of a statistical life. On average, the overall health effect of the modal shift is negative. This is largely due to the very high pedestrian and bike road injury rates in Italian cities. The negative effect of increased air pollution intake is negligible if compared with the effect of road injuries. In the case of bikes/e-bikes, the overall health effect is positive in cities characterised by good cycling infrastructure.

Trends in transport injuries burden and risk factors among children under 14 years old in China: 1990–2019

BackgroundTransport injuries (TI) remains one of leading causes of death in children in China. This study aimed to analyze the temporal trend of disease burden and associated risk factors of TI among children aged 0–14 years in China, utilizing data from 1990 to 2019.MethodsWe retrieved data of disease burden and risk factors of TI among children aged 0–14 year in China from 1990 to 2019 from the Global Burden of Disease (GBD) dataset. We estimated incidence rate, death rate, and disability adjusted life years (DALYs) rate with a 95% uncertainty interval (95% UI), stratified by age, sex, and all type-road users. Trends in disease burden with annual percentage changes (APC) and average annual percent change (AAPC) were performed by Joinpoint regression model.ResultsThe incidence rate (AAPC = 1.18%, P < 0.001) of TI among children aged 0–14 years showed an increasing trend, whereas mortality rate (AAPC = -3.87%, P < 0.001) and DALYs rate (AAPC = -3.83%, P < 0.001) decreased annually. Notably, boys experienced a higher increase in incidence (1.30%) compared to girls (1.06%), but a faster decrease in mortality and DALYs rate (-3.90% vs. -3.82%, -3.88% vs. -3.79%, respectively) (Pall < 0.001). Declines in death rates and DALYs rates were observed across all age groups (Pall < 0.001), while remained the highest among children aged 0–4 in 2019. Among different road-type users, cyclist road injuries were identified as the primary cause of TI (182.3 cases per 100,000) while pedestrians were the group with the highest mortality (2.9 cases per 100,000) and DALYs rate (243 cases per 100,000) in 2019. Besides, alcohol use was a significant risk factors for TI, while low temperature appeared to be a protective factor.ConclusionFuture efforts must prioritize raising awareness among children and their guardians to mitigate the disease burden of TI in children. It’s critical to enhance preventive interventions for boys, children aged 0–4 and vulnerable road users such as pedestrians and cyclists in future.

Global, regional, and national burdens of mild traumatic brain injuries from 1990-2019: findings from the Global Burden of Disease Study 2019 - a cross-sectional study.

The objective of this study was to utilize data from the Global Burden of Disease Study (GBD) 2019 to estimate the patterns and prevalence of mild traumatic brain injury (mTBI) from 1990 to 2019, with the intention of informing the development of efficacious intervention strategies. Data from the GBD 2019 were examined to determine the prevalence, incidence, and rates of years lived with disability (YLDs) associated with mTBI across global geographic populations from 1990 to 2019. To assess temporal patterns, estimated annual percentage changes (EAPCs) and age-standardized rates were computed. Additionally, an age-period-cohort model (APC model) framework was employed to analyze potential trends in incidence based on age, period, and birth cohort. In 2019, there were a total of 12,268.5 thousand incident cases (95% uncertainty interval [UI] 992.66 to 1,602.07), 11,482.5 thousand prevalent cases (95% UI 107.59 to 123.52), and 1,366.9 thousand YLDs (95% UI 96.36 to 183.35) of mTBI worldwide. The age-standardized rates (ASRs) of incidence, prevalence, and YLDs exhibited a decline from 1990 to 2019. Across all age groups, males had higher prevalence, incidence and YLDs rates. Furthermore, middle-aged and elderly adults experienced a greater disease burden. The primary causes of the global mTBI burden in 2019 were falls and road injuries. According to the APC model, the age effect trend exhibited a similar pattern across individual sociodemographic index (SDI) groups, characterized by an initial increase, followed by a decrease and a subsequent increase. Regarding the period effect, each SDI group demonstrated variation, with the middle SDI group notably displaying a consistent increase. Furthermore, in terms of the birth effect, the middle-SDI group experienced the most substantial and continuous increase. The global incident cases and prevalent cases of mTBI increased significantly from 1990 to 2019, with a heavier burden observed in males, older adults, and in low SDI such as Afghanistan. More efforts are needed in the prevention and management of mTBI, such as reducing the incidence of falls among older people and building safer road transport facilities to reduce the burden of mTBI.

Impact of COVID-19 pandemic on road traffic injuries in Iran: An interrupted time-series analysis.

Globally, the COVID-19 pandemic has affected the number of road accidents and deaths caused by them. The present study aimed to identify the effect of this epidemic on traffic accidents and their casualties in Iran. In this study, Interrupted Time Series Analysis (ITSA) was used in a semi-experimental design to measure the impact of the restrictive policies of COVID-19 on road accidents. Data were collected retrospectively from the Iran Red Crescent Society data set for 31 provinces from March 2017 to February 2022. The information related to the number of road accidents, injuries, deaths, and deaths in the hospital was collected. The Newey-West method is used for estimation. Statistical analyses were carried out using R software version 3.6.1. Since February 2020 in Iran, the reduction in the number of road accidents and the number of injuries and deaths in these accidents was significant at 5% but the reduction of deaths in the scene and hospital was significant at 10%. In general, for all variables, the reduction trend was established only in the first months, and then it had an upward trend. In the early months of the COVID-19 epidemic in Iran, the number of road accidents and their casualties decreased. Policies restricting traffic, quarantine, and fines for violators can be reasons for changing people's behavior and travel patterns and also lead to a reduction in traffic accidents and fatalities. Such studies can explain the importance of the policies in changing behavioural patterns and can be used as a guide in future policies.

Orthopaedic and trauma research in Tanzania: A scoping review.

Tanzania is disproportionately burdened by musculoskeletal injuries as it faces unique challenges when dealing with trauma care. This scoping review aims to summarize and assess the current state of orthopaedic and trauma research in Tanzania. By identifying key themes, trends, and gaps in the literature, this review seeks to guide future research initiatives catered specifically to the needs of Tanzania's healthcare system. Utilizing the PRISMA-ScR protocol, OVID Medline, PubMed, and CINAHL databases were searched from inception to June 17, 2023, using keywords such as "Orthopaedics" "Trauma" and "Tanzania". One hundred and ninety-two eligible studies were included and the Arksey and O'Malley framework for scoping studies was followed. There was a notable growth of relevant publications from 2015 onward, with peaks in growth in the years 2019, 2021, and 2020. The studies employed diverse research methodologies, with cross-sectional (n = 41, 21%) and prospective studies (n = 39, 20%) being the most prevalent, and randomized-controlled trials being the least prevalent methodology, making up eight studies (4.2%). The most common study themes were trauma (n = 101, 52.6%), lower extremity (n = 31, 16%), and spine-related issues (n = 27, 14%). Only three studies looked at work-related injuries (1.6%). Road traffic injuries (RTIs) were the most common mechanism of trauma in 77.0% of the trauma focused studies. Fifty-three percent of the studies were conducted by a majority of Tanzanian authors. This scoping review highlights various trends in orthopaedic and trauma research in Tanzania, with a particular emphasis on road traffic-related injuries. Various gaps are explored, including a lack of research on work-related injuries and a paucity of experimental research. Our findings underline areas where future research is warranted. The future of orthopaedic and trauma care in Tanzania depends on the efforts and collaboration of both local and international stakeholders.

Smart IoT based Accident Monitoring and Rescue System

Today's drivers face a significant danger of vehicle accidents; hence, it is critical to devise innovative strategies to mitigate their impact and expedite emergency responses, especially considering the significant mortality rate. The proposed Internet-based Automatic Accident Detection and Rescue System (IoT-ADRS) optimizes accident detection and rescue operations by leveraging Internet of Things (IoT) technology. The framework combines several sensors, such as accelerometers, gyroscopes, ultrasonic sensors, GPS modules, and MQ3 sensors, to precisely identify accidents in real time. The Arduino microcontroller analyzes data from several sensors to identify accidents. The system employs GSM modules to transmit critical information, including the exact position and time of the event, to emergency services in real time upon detecting an accident. It examines key components and their connections to gather important data, quickly sound alarms, and manage resources efficiently. This comprehensive study shows that IoT-ADRS improves accident response protocols, saves lives, and reduces the severity of road injuries.
