METHODS: Select databases were searched in 5/2023. Included articles involved an/a 1. aim to develop or investigate firearm safety interventions, 2. focus on adults 50 years and older, and 3. primary analysis. RESULTS: The search yielded 10 articles which primarily focused on firearm safety counseling with older adults with suicide risk or emerging impairment...

The study of firearm violence in Mexico has primarily focused on homicides and trafficking. Less attention has been given to understanding how firearms affect other crimes and facilitate criminal activity beyond drug markets. By analyzing two questions, this study explores the role of firearms in extortions perpetrated in Mexico from 2012 to 2021. Questions are: What is the likelihood of reporting extortions to the police if offenders exhibited firearms? What is the likelihood of compliance with demands when offenders are armed with firearms? We obtained data from Mexico's National Crime Victimization Surveys and analyzed 2,619 extortions reported from 2012 to 2021...

This research examines the notion of defensive gun ownership using the Dualistic Model of Passion. We hypothesized that an obsessive (vs. harmonious) passion for guns would be associated with a belief in a dangerous world (BDW). We expected this relationship to intensify in threatening contexts, leading to a more expansive view on defensive gun ownership. We tested this hypothesis across three threat contexts: a gun-control message (Study 1, N = 342), a live shooting simulation (Study 2, N = 398), and the aftermath of the Christchurch mass shootings (Study 3, N = 314)...

Familicide is rare; however, the high victim counts in each incident and context surrounding these killings underscore the need for further research. The purpose of this study is to gain a better understanding of the circumstances surrounding familicide in Canada. Using univariate statistics, this study analyzed 26 incidents of familicide that occurred in Canada between 2010 and 2019. The results show that familicide is a gendered crime involving primarily male accused who often target female victims, have a history of domestic violence, and commit the killings using firearms...

INTRODUCTION: The COVID-19 pandemic created difficulties in access to care. There was also increased penetrating trauma in adults, which has been attributed to factors including increased firearm sales and social isolation. However, less is known about the relationship between the pandemic and pediatric trauma patients (PTPs). This study aimed to investigate the national incidence of penetrating trauma in PTPs, hypothesizing a higher rate with onset of the pandemic. We additionally hypothesized increased risk of complications and death in penetrating PTPs after the pandemic versus prepandemic...

Cartridge cases are commonly collected at crime scenes involving firearms. One of the stages in forensic examination is the determination of the type and model of firearms based on the class characteristics of these cartridge cases. A firearm examiner evaluates the class characteristics on the basis of their knowledge and experience, and by referring to collections of cartridge cases representing class characteristics of different firearms, special databases and reference books. However, this process is highly subjective...

Efforts to explore the macrolevel determinants of police-involved homicides have expanded in recent years due in part to increased scrutiny and media attention to such events, and increased data availability of these events through crowdsourced databases. However, little empirical research has examined the spatial determinants of such events. The present study extends the extant macrolevel research on police-involved homicides by employing an underutilized spatial econometric model, the spatial Durbin model (SDM), to assess the direct and indirect county effects of racial threat, economic threat, social disorganization, and community violence on police killings within and between US counties from 2013 through 2020...

OBJECTIVE: Firearm violence constitutes a public health crisis in the United States, but comprehensive data infrastructure is lacking to study this problem. To address this challenge, we used natural language processing (NLP) to classify court record documents from alleged violent crimes as firearm-related or non-firearm-related. MATERIALS AND METHODS: We accessed and digitized court records from the state of Washington (n = 1472). Human review established a gold standard label for firearm involvement (yes/no)...

INTRODUCTION: Alcohol use is involved in a large proportion of homicides and suicides each year in the United States, but there is limited evidence on how policies targeting alcohol influence violence in the U.S. CONTEXT: Extant studies generally focus on individual policies in isolation of each other. This study examines of the effects of changes in states' alcohol policy restrictions on overall homicide and suicide rates and firearm-related homicide and suicide rates using a holistic measure of states' alcohol policy environments...

INTRODUCTION: There has been a sharp climb in the Unites States' death rate among opioid and other substance abuse patients, as well as an increased prevalence in gun violence. We aimed to investigate the association between substance abuse and gun violence in a national sample of patients presenting to US emergency departments (EDs). METHODS: We queried the 2018-2019 Nationwide Emergency Department Sample for patients ≥18 years with substance abuse disorders (opioid and other) using International Classification of Diseases, 10th Revision, Clinical Modification codes...

In June 2022, the U.S. federal government passed its first major firearm policy since the Brady Handgun Violence Prevention Act of 1993, the Bipartisan Safer Communities Act (BSCA). Summative content analysis was used to explore how the social problem of firearm violence was outlined in both policies, with the goal of extracting the social issue's definition from the policies' approaches to solving it. Both policies do not outline the various types of firearm violence, nor the disproportionate effect of firearm violence on certain populations...

Not much is known about the perpetrators of male homicide in South Africa, which has rates seven times the global average. For the country's first ever male homicide study we describe the epidemiology of perpetrators, their relationship with victims and victim profiles of men killed by male versus female perpetrators. We conducted a retrospective descriptive study of routine data collected through forensic and police investigations, calculating victim and perpetrator homicide rates by age, sex, race, external cause, employment status and setting, stratified by victim-perpetrator relationships...

The Society for Maternal-Fetal Medicine (SMFM) acknowledges gun violence as a public health crisis in the United States, with a significant impact on pregnant and postpartum people. We recognize the urgent need for a robust, equitable, data-driven approach to mitigate the impact of access to firearms and accompanying violence on pregnant and postpartum individuals and communities. As such, SMFM endorses the following policy principles: - SMFM calls on relevant government agencies and public funders to support and finance anti-violence and firearm safety research, public health surveillance activities, education, and other initiatives...

BACKGROUND: Evidence about which firearm policies work, to what extent, and for whom is hotly debated, perhaps partly because variation in research methodology has produced mixed and inconclusive effect estimates. We conducted a scoping review of firearm policy research in the health sciences in the United States, focusing on methodological considerations for causal inference. METHODS: We identified original, empirical articles indexed in PubMed from 1/1/2000-9/1/2021 that examined any of 18 pre-specified firearm policies...

<b/> Background: There is conflicting evidence on the suicide rates of different public safety personnel (PSP). There have been few studies that compare suicides in PSP with the general population and none that have used a detailed comparison of coroner records. Aims: The current study estimates suicide rates among different PSP and compares PSP suicides with the general population. Method: We identified coroner records of PSP suicides from January 2014 to December 2018 and compared each one to two matched general population controls...

Traumatic brain injury (TBI) is a global health challenge; however, penetrating brain injury (PBI) remains under-represented in evidence-based knowledge and research efforts. This study utilized data from the Trauma Quality Improvement Program (TQIP) of the National Trauma Data Bank (NTDB) to investigate outcomes of PBI as compared with clinical-severity-matched non-penetrating or blunt TBI. A total of 1765 patients with PBI were 1:1 propensity score-matched for clinical severity with blunt TBI patients. The intent of PBI was self-inflicted in 34...

IMPORTANCE: Little is known about support for and willingness to engage in political violence in the United States. Such violence would likely involve firearms. OBJECTIVE: To evaluate whether firearm owners' and nonowners' support for political violence differs and whether support among owners varies by type of firearms owned, recency of purchase, and frequency of carrying a loaded firearm in public. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional nationally representative survey study was conducted from May 13 to June 2, 2022, among US adult members of the Ipsos KnowledgePanel, including an oversample of firearm owners...

IMPORTANCE: Interstate gun flow has critical implications for gun violence prevention, as gun transfers across state lines can undermine local gun control policies. OBJECTIVE: To identify possible gun trafficking routes along interstate highways in the US. DESIGN, SETTING, AND PARTICIPANTS: This repeated-measures, ecological, cross-sectional study used data from the Bureau of Alcohol, Tobacco, Firearms and Explosives from January 1, 2010, to December 31, 2019, to examine associations between interstate connections via 13 highways that each spanned at least 1000 miles and interstate traced gun transfer counts for the 48 contiguous United States...

Suicide remains a leading cause of death in the United States (U.S.) Armed Forces. Access to firearms increases the risk of death by suicide due to the high lethality of firearm-related injuries (~90% in suicide attempts) and the highly dynamic nature of suicide which includes rapid change from low- to high-risk states. Critical gaps remain in research, programming, and communication amongst scientists, Department of Defense (DoD) programmatic leaders, front-line commanders, and service members. To enhance communication and coordination, in June 2022, the first-ever national "Firearm Suicide Prevention in the Military: Messaging and Interventions Summit " was held, with discussion of Firearm Leadership, a concept that emphasizes the importance of communication about lethal means safety (LMS) among military leaders and service members...
