RESUMEN

INTRODUCTION: The United States (US) holds the highest personal firearm ownership among industrialized nations, with implications for firearm-related deaths tied to increased per capita gun ownership and varying gun laws. This study examines the influence of gun law strength on legal firearm transactions, positing a correlation between stronger laws and reduced transactions. The analysis, focused on the stress-laden COVID-19 pandemic, evaluates handgun, long gun, and multiple gun transactions in 2020 and 2021 compared to 2018-2019. METHODS: The Giffords Gun Law scorecard categorized states into the top 25 "strong" and bottom 25 "weak" gun law groups. Multivariate linear regressions assessed the association between strong gun law states and monthly National Instant Criminal Background Check System (NICS) data from 2018 to 2021. The study queried NICS for handgun, long gun, and multiple gun transactions, comparing median monthly transactions in 2018 and 2019 to 2020 and 2018-2020 to 2021. RESULTS: When evaluating gun law strength through multivariate linear regression models, stronger gun law states had fewer monthly NICS transactions for handguns, long guns, and multiple guns in 2020 and 2021 versus all comparison years (all P < .05). However, from 2018-2019 to 2020 and 2018-2020 to 2021, median monthly NICS transactions per 100,000 people for all gun types increased (all P < .05). CONCLUSION: Stricter gun laws correlated with decreased firearm transactions in stronger law states, yet handgun, long gun, and multiple gun transactions increased during the pandemic years of 2020 and 2021. Therefore, strengthening firearm legislation may be protective against the proliferation of firearms, which warrants further research.

RESUMEN

Background: Over 48,000 people died by firearm in the United States in 2021. Firearm violence has many inciting factors, but the full breadth of associations has not been characterized. We explored several state-level factors including factors not previously studied or insufficiently studied, to determine their association with state firearm-related death rates. Methods: Several state-level factors, including firearm open carry (OC) and concealed carry (CC) laws, state rank, partisan lean, urbanization, poverty rate, anger index, and proportion of college-educated adults, were assessed for association with total firearm-related death rates (TFDR). Secondary outcomes were firearm homicide (FHR) and firearm suicide rates (FSR). Exploratory data analysis with correlation plots and ANOVA was performed. Univariable and multivariable linear regression on the rate of firearm-related deaths was also performed. Results: All 50 states were included. TFDR and FSR were higher in permitless OC and permitless CC states. FHR did not differ based on OC or CC category. Open carry and CC were eliminated in all three regression models due to a lack of significance. Significant factors for each model were: 1) TFDR - partisan lean, urbanization, poverty rate, and state ranking; 2) FHR - poverty rate; 3) FSR - partisan lean and urbanization. Conclusions: Neither open nor concealed carry is associated with firearm-related death rates when socioeconomic factors are concurrently considered. Factors associated with firearm homicide and suicide differ and will likely require separate interventions to reduce firearm-related deaths. Key message: Neither open carry nor concealed carry law are associated with total firearm-related death rate, but poverty rate, urbanization, partisan lean, and state ranking are associated. When analyzing firearm homicide and suicide rates separately, poverty rate is strongly associated with firearm homicide rate, while urbanization and partisan lean are associated with firearm suicide rate.

RESUMEN

The regions of Provence-Alpes-Côte d'Azur and Corsica in south-east France are regularly affected by firearm deaths, and a large amount of data has been collected by our forensic institute. We carried out a single-center retrospective descriptive study of the records of our institute between January 1, 2011, and 31 December, 2018, relating to firearm deaths (homicides and suicides). There were 302 cases (218 homicides and 84 suicides). The anatomic locations most frequently involved were the thorax, abdomen and head, in that order, in homicides and the head in suicides. More than 80% of the homicides in our series had more than one wound complex and nearly one in four homicides had more than 7. The weapon most frequently used in suicides was a hunting smooth bore gun, followed by the 9mm Luger and then by the .22 Long Rifle. In homicides, the caliber most frequently used was the 7.62 × 39 (29.6%), followed by the 9mm Luger (29%) and lastly by hunting calibers (27%). More than 10% of cases involved two weapons of two different calibers. Our study, which used a dual forensic and ballistic approach, was carried out in one of the most heavily populated regions of metropolitan France. We observed very few similarities with the literature regarding type of caliber and wound complexes. This may be explained, among other factors, by differences in political, societal or cultural contexts.

RESUMEN

BACKGROUND: Venezuela is one of the most violent countries in the world. According to the United Nations, homicide rates in the country increased from 32.9 to 61.9 per 100 000 people between 2000 and 2014. This upsurge coincided with a slowdown in life expectancy improvements. We estimate mortality trends and quantify the impact of violence-related deaths and other causes of death on life expectancy and lifespan inequality in Venezuela. METHODS: Life tables were computed with corrected age-specific mortality rates from 1996 to 2013. From these, changes in life expectancy and lifespan inequality were decomposed by age and cause of death using a continuous-change model. Lifespan inequality, or variation in age at death, is measured by the standard deviation of the age-at-death distribution. RESULTS: From 1996 to 2013 in Venezuela, female life expectancy rose 3.57 [95% confidence interval (CI): 3.08-4.09] years [from 75.79 (75.98-76.10) to 79.36 (78.97-79.68)], and lifespan inequality fell 1.03 (-2.96 to 1.26) years [from 18.44 (18.01-19.00) to 17.41 (17.30-18.27)]. Male life expectancy increased 1.64 (1.09-2.25) years [from 69.36 (68.89-59.70) to 71.00 (70.53-71.39)], but lifespan inequality increased 0.95 (-0.80 to 2.89) years [from 20.70 (20.24-21.08) to 21.65 (21.34-22.12)]. If violence-related death rates had not risen over this period, male life expectancy would have increased an additional 1.55 years, and lifespan inequality would have declined slightly (-0.31 years). CONCLUSIONS: As increases in violence-related deaths among young men (ages 15-39) have slowed gains in male life expectancy and increased lifespan inequality, Venezuelan males face more uncertainty about their age at death. There is an urgent need for more accurate mortality estimates in Venezuela.

RESUMEN

The misuse of alcohol has a particularly detrimental effect and is one of the most significant public health problems in South Africa and it also has an impact on the criminal justice system with evidence of association between high levels of alcohol and risk-taking behaviour, committing crimes, or being a victim of crime. A global trend has been set worldwide with alcohol being one of the most common drugs found in post mortem specimens and especially with regard to cases admitted for medico-legal autopsies. The influence of alcohol on the cause of death is either a contributory or an underlying factor in a substantial number of violent deaths. We retrospectively reviewed 1455 cases, in which alcohol was taken, of 2344 medico-legal autopsies done in 2009. We found that 47% of the cases tested positive for alcohol, with the reported blood alcohol concentrations varying from 0.01 to 0.95g per 100ml (mean=0.16±0.11g per 100ml) with the highest proportion being in the 0.10-0.19g per 100ml range. A breakdown of the results showed that road traffic accidents, assaults and firearm-related deaths predominated the alcohol-positive cases. The results showed that there was a definite correlation between alcohol consumption and the incidence of other that natural deaths.
