Firearm homicide is the leading cause of violence-related youth mortality. To inform prevention efforts, we analyzed event-level data to identify unique precursors to firearm conflicts. Youth (ages:14-24) seeking Emergency Department (ED) treatment for assault or for other reasons and reporting past 6-month drug use were enrolled in a 2-year longitudinal study. Time-line follow-back substance use/aggression modules were administered at baseline and each 6-month follow-up. Violent non-partner conflicts were combined across time-points...

Extant literature provides evidence for the frequent use and lethality of firearms in suicide and the ability of means safety measures to prevent suicides; however, little evidence exists to provide an understanding of the characteristics that differentiate suicide decedents who die by firearm from those who die by other methods. In this study, we build on prior findings regarding the characteristics of those who die by firearms by examining the relationship between social and economic policy views and both firearm ownership and death by firearm in a sample of 267 American suicide decedents...

INTRODUCTION: Traumatic spinal cord injury (SCI) is one of the major causes for poor outcomes of pregnancy. Injury during pregnancy is uncommon; therefore, outcome data are scarce. This case series presents outcomes of pregnancy in five women who sustained SCI during their pregnancies. CASE PRESENTATION: Five women who sustained SCIs during pregnancy (age range: 24-38 years) were identified and included in this case series. The causes of SCI in this population were fall from heights (cases 1 and 2), road traffic accidents (cases 3 and 4) and firearm injury (case 5)...

BACKGROUND: Trauma in pregnancy remains an important but understudied public health issue. We aimed to determine the prevalence of interpersonal violence in our pregnant trauma population (including pediatric) over the last 20 years, from our Level I trauma center. METHODS: We conducted a descriptive, retrospective chart review to identify all pregnant trauma patients between Jan 1993 and Sept 2013. Pediatric was ≤18 years of age. We evaluated demographics, mechanism of injury, injury location, disposition, and outcome data...

BACKGROUND: Firearm injuries disproportionately affect young, male, non-White populations, causing substantial individual and societal burden. Annual costs for hospitalized firearm injuries have not been widely described, as most previous cost studies have focused on lifetime costs. We examined a nationally-representative database of hospitalizations in the US to estimate per-hospital and overall hospital costs for firearm injuries by intent, type of weapon, and payer source. METHODS: We conducted a retrospective cohort study of all firearm injury hospitalizations in the National Inpatient Sample from 2003 through 2013...

It is a well-known fact that blank cartridge guns can cause penetrating and even fatal injuries when discharged in contact or at very close ranges. In these cases, the gas jet perforates the skin leaving an entrance wound similar to that from a conventional gun. In order to investigate the wound morphology in contact shots from blank firearms, test shots were fired at composite models of pig skin and gelatin blocks using three different calibre 9-mm blank cartridge handguns (two pistols and one revolver) and two types of ammunition...

The purpose of this study was to investigate the difference in mandibular trauma caused by two mechanisms for the delivery of missile injuries: firearms and improvised explosive devices (IEDs). The data investigated included sex, age, mechanism of injury, and other clinical and radiographic manifestations. Seventy consecutive patients, predominantly male, with a mean age of 28.6±14 years (range 2-60 years) were enrolled: 38 patients (54.3%) sustained mandibular fractures caused by bullet injuries and 32 patients (45...

Despite broad support for policies requiring that prospective firearm owners receive training before acquiring a firearm, little is known about the scope and content of firearm training in the USA. Nationally representative surveys conducted in 1994 estimated that 56%-58% of the US firearm owners had received formal firearm training. We conducted a nationally representative survey in 2015 (n=3932; completion proportion=55%) to update those estimates and characterise training contents. 61% of firearm owners and 14% of non-owners living with a firearm owner reported having received formal firearm training...

Kaifeng Zhang, Yaping Luo, Peng Zhou
Reproducibility of characteristic marks on fired cartridge cases from five Chinese Norinco QSZ-92 9×19mm pistols over the course of 3070 shots is addressed using an Evofinder(®) system. The first 20 cartridges are all studied, while one random sample out of every ten consecutively fired cartridge cases is studied for the rest 3050 rounds. As such, a total of 325 cartridges are entered into the system for each pistol and a database consisting of 1625 cartridges from five pistols is established in this paper...

INTRODUCTION: Gun violence is a substantial public health problem accounting for significant physical, psychological and financial costs. While aggregate data sources demonstrate decreasing rates of firearm violence, analyses from individual trauma centers have shown that mortality and injury severity from GSWs are increasing. To evaluate the evolving characteristics of gun violence in our region, we studied all GSWs admitted to our trauma center over a twenty-year period. METHODS: A retrospective analysis of all newly admitted patients with GSWs was performed from 1996 to 2016...

Xiao Hui Tai, William F Eddy
When a gun is fired, it leaves marks on cartridge cases that are thought to be unique to the gun. In current practice, firearms examiners inspect cartridge cases for "sufficient agreement," in which case they conclude that they come from the same gun, testifying in courts as such. A 2016 President's Council of Advisors on Science and Technology report questioned the scientific validity of such analysis (President's Committee of Advisors on Science and Technology, Washington, DC, Executive Office of the President)...

OBJECTIVE: To examine 1) temporal trends between 2005 and 2014 in the three most frequently used suicide means (firearms, hanging/suffocation, alcohol/drug/medicine overdose) by decedents aged 50+ years and 2) associations of suicide means with sociodemographic and precipitating factors. METHODS: The National Violent Death Reporting System, 2005-2014, provided data (N = 46,857). Suicide means were identified from ICD-10 codes for underlying cause of death and coroner/medical examiner (CME) reports...

Justin N Kirk, Eric F Law, Keith B Morris
When a firearm is discharged, the individual marks of the breech face and firing pin are imprinted onto the primer of the cartridge case. These individual marks are reproducible between shots; however, over a large number of consecutive shots, it has been observed that minute changes in these individual marks may occur. Changes in individual marks may affect an examiner in their ability to identify or eliminate and may change the magnitude of a likelihood ratio, depending on the system used by the laboratory, but the effect that these changes have on the Integrated Ballistic Identification System (IBIS(®)) is largely unknown...

BACKGROUND: This paper argues that the decline in the availability of long-term, intensive mental health services, particularly through state mental health hospital systems, has had negative impacts on firearm-related deaths and possibly on the incidence of mass shooting events. AIMS: Establish the effect of reduced availability of long-term, intensive mental health treatment on firearm-related violence in the United States. METHOD: Ordinary least squares regressions on cross-sectional data of US states...

This ballistics study examines whether saline breast implants can decrease tissue penetration in firearm injuries. We hypothesize that the fluid column within a saline breast implant can alter bullet velocity and/or bullet pattern of mushrooming. The two experimental groups included saline implants with 7.4 cm projection and a no implant group. The experimental design allowed the bullet to pass-through an implant and into ballistics gel (n = 10) or into ballistics gel without passage through an implant (n = 11)...

Victims of homicide and attempted homicide are not uncommon in Sweden. We therefore aimed to study these victims to understand their injuries, their cause of death, and their relationship to the offender. All cases during five years in a district court in Sweden, where an offender had been convicted for homicide or attempted homicide, were identified and the court documents reviewed. Nineteen victims were identified; 14 males and five females, with an average age of 39.1 years. Although knife/sharp weapon was the most common weapon used, the use of firearm caused more deaths...

PURPOSE: Firearm injuries (FAIs) are a major public health issue in the United States. The objective of this study was to examine characteristics and outcomes of patients presenting to emergency departments (EDs) with facial fractures attributed to FAIs. MATERIALS AND METHODS: The Nationwide Emergency Department Sample for the years 2008 to 2013 was used. All patients who visited EDs with FAIs and facial fractures were selected. The study focused on the following variables: 1) demographic characteristics, 2) types of facial fractures, 3) disposition status after ED visit or subsequent hospitalization, 4) charges (ED and hospitalization), and 5) patient outcomes...
