Global burden and trends of firearm violence in 204 countries/territories from 1990 to 2019

study

BACKGROUND

Mexico is among the countries with the highest mortality rates by firearms worldwide. We aimed to analyse the trend in the burden of firearm violence (FV) by age and sex in Mexico at a national and subnational level, and the association between this burden and the Sociodemographic Index.

METHODS

We used estimates from the Global Burden of Disease (GBD)-2019 study for the analysis of FV mortality, premature mortality and disability for all available age-groups and by sex. The GBD data separates FV into three categories-interpersonal violence from firearms, unintentional injuries from firearms and self-harm from firearms. We used a joinpoint regression analysis to analyse the temporal trends of the FV burden.

RESULTS

FV exhibited a non-significant increase. By cause, there was a significant increase in the burden of interpersonal violence from firearms, a non-significant decrease in the burden of self-harm from firearms and a significant decrease in the burden of unintentional injuries from firearms. Most of the FV burden is attributed to interpersonal violence from firearms. Almost the entirety of the burden of FV results from premature mortality. The incidence of FV disability adjusted life years (DALYs) was significantly higher among males than females, and was most concentrated in males aged 20-44 and females aged 15-49. Significant heterogeneity in FV DALY trends was observed at the subnational level.

CONCLUSION

These results may help to better understand the burden of FV and help the design and implementation of national and local preventive policies.

Characteristic of school injuries in Asia: a cross-national, multi-center observational study

BACKGROUND

To prevent school injuries, thorough epidemiological data is an essential foundation. We aimed to investigate the characteristics of school injuries in Asia and explore risk factors for major trauma.

METHODS

This retrospective study was conducted in the participating centers of the Pan-Asian Trauma Outcome Study from October 2015 to December 2020. Subjects who reported "school" as the site of injury were included. Major trauma was defined as an Injury Severity Score (ISS) value of ≥16.

RESULTS

In total, 1305 injury cases (1.0% of 127,715 events) occurred at schools. Among these, 68.2% were children. Unintentional injuries were the leading cause and intentional injuries comprised 7.5% of the cohort. Major trauma accounted for 7.1% of those with documented ISS values. Multivariable regression revealed associations between major trauma and factors, including age, intention of injury (self-harm), type of injury (traffic injuries, falls), and body part injured (head, thorax, and abdomen). Twenty-two (1.7%) died, with six deaths related to self-harm. Females represented 28.4% of injuries but accounted for 40.9% of all deaths.

CONCLUSIONS

In Asia, injuries at schools affect a significant number of children. Although the incidence of injuries was higher in males, self-inflicted injuries and mortality cases were relatively higher in females.

IMPACT

Epidemiological data and risk factors for major trauma resulting from school injuries in Asia are lacking. This study identified significant risk factors for major trauma occurring at schools, including age, intention of injury (self-harm), injury type (traffic injuries, falls), and body part injured (head, thoracic, and abdominal injuries). Although the incidence of injuries was higher in males, the incidence of self-harm injuries and mortality rates were higher in females. The results of this would make a significant contribution to the development of prevention strategies and relative policies concerning school injuries.

The trends of interpersonal violence burden in Latin America, 1990 to 2019: secondary data analysis from the global burden of disease study

OBJECTIVES

We aimed to analyse the trends of interpersonal violence (IV) in Latin America (LA) between 1990 and 2019 for females and males at a national level.

STUDY DESIGN

Cross-sectional descriptive study.

METHODS

Following the 2019 Global Burden of Disease study we report IV mortality, premature mortality, years lived with disability and disability-adjusted life-years (DALYs) in LA by sex. To estimate the DALYs trends, we conducted a Joinpoint regression analysis.

RESULTS

Across all LA countries, IV burden was higher among males. Most of the IV burden was attributable to premature death, with a higher percentage in men than women. The burden of IV was most pronounced within the 15 to 39 age-groups in the majority of countries. Physical violence (PV) by firearm was the main cause of IV in LA, followed by PV by other means. Women in LA experienced at least twice as many sexual violence DALYs as men. IV in LA exhibited heterogeneous trends, with certain countries witnessing a significant decline in the IV DALYs rate, while others displayed a significant increase.

CONCLUSIONS

Our results show the great heterogeneity of IV burden present in the region as the trends varied from one country to another. Policing and criminal justice institutions in LA have failed to reduce crime and violence. Thus, tailored preventive measures and public policies that account for the specific context and geographical areas where this phenomenon is prevalent are urgently needed.

Burden of stroke in China and the different SDI regions over the world

Background

Stroke is a significant global health issue, ranking as the second leading cause of death and the third leading cause of death and disability combined. This study aimed to examine the changes and differences in stroke burden from 1990 to 2019 in China and various global socio-demographic index (SDI) regions.

Methods

Data were obtained from the Global Burden of Diseases Study 2019, which included the incidence, prevalence, mortality, disability-adjusted life years (DALY), years of life with disability (YLD), and years of life lost (YLL) of stroke. The change trend of stroke burden was assessed based on age-standardised rates per 100 000 person-years and estimated annual percentage changes. The average annual rate of change in stroke burden was analysed using the average annual percentage change from 1990 to 2019. Pearson correlation analysis was used to explore the strength and direction of the correlation between stroke burden and SDI.

Results

Regions with high SDI showed the largest decline in age-standardised incidence, death, DALY, YLD, and YLL rates of stroke from 1990 to 2019. China experienced the largest increase in age-standardised prevalence and YLD rates of stroke from 1990 to 2019. There were significant differences in the average annual percent change in stroke burden among the majority of SDI regions. The burden for stroke at the national level was inversely correlated with SDI, despite some exceptions (Incidence: R = -0.417, P < 0.001; prevalence: R = -0.297, P < 0.001; mortality: R = -0.510, P < 0.001; DALY: R = -0.550, P < 0.001; YLD: R = -0.125, P = 0.075; YLL: R = -0.569, P < 0.001).

Conclusions

There were significant differences in the stroke burden across different regions with varying SDI levels from 1990 to 2019. The age-standardised prevalence rate and attributable disability burden of stroke remain substantial in different SDI regions, making it a major contributor to the overall disease burden. The severe burden of stroke highlights the importance of primary and secondary stroke-prevention strategies. Therefore, future strategies to prevent and reduce the burden of stroke should be formulated and implemented according to the SDI of each country.

Demographics, Radiological Findings, and Predictors of Prolonged Hospitalization in Civilian Gunshot Wound Patients

Objective

This study aims to characterize the demographic, clinical, and radiological features of gunshot wound (GSW) patients as well as identify predictors of prolonged hospitalization.

Methods

In this retrospective study, a consecutive sampling method was used, including all patients with GSWs in any anatomical region. Data collection included demographic and clinical information, radiological findings, treatment specifics, and outcome variables, such as hospitalization length of stay (LOS) as the primary outcome. To identify predictive factors associated with prolonged LOS, logistic regression analysis was used.

Results

We studied 212 GSW cases, including 95.8% were men and 4.2% were women. The mean age of the studied group was 30.17±7.80 years. GSWs occurred in extremities (80.2%), abdomen (9.0%), thorax (4.7%), and head or neck (5.2%). Two patients (0.9%) had both abdominal and thoracic GSWs. The most prevalent radiological study was an X-ray (83.0%). Patients with head and neck GSWs had the longest emergency department stay, while patients with abdominal GSW patients had the shortest (p=0.068). The highest rates of blood product transfusion were observed in abdominal GSWs (63.2%), emergency surgery (63.2%), and ICU admission (42.1%). Head and neck GSWs had the longest hospitalization LOS (7.5 days). Longer LOS was significantly associated with abnormalities in radiological findings, receiving blood products, and ICU admission (p≤0.001). Significant predictors of prolonged LOS were major abnormalities in radiological findings [odds ratio (OR)=5.3; 95% confidence interval (CI):2.8-10.2], head and neck GSWs (OR=6.1; 95% CI:1.2-31.9), and blood product transfusion (OR=4.1; 95% CI: 1.0-16.3).

Conclusion

This study provides insights into factors influencing prolonged hospitalization in GSW patients, highlighting the importance of radiological findings, head and neck injuries, and blood product transfusion.
