This research implements a fractographic approach to investigate the relationships between kinetic energy, firearm-to-target distance, and various aspects of fracture behavior in gunshot trauma. Gunshot experiments were performed on pig scapulae (n = 30) using three firearms generating different muzzle (initial) kinetic energies, including a 0.32 pistol (103 J), 0.40 pistol (492 J), and 0.308 rifle (2275 J). Specimens were shot from two distances: 10 cm (n = 15) and 110 cm (n = 15)...

Acute kidney injury (AKI) after cardiac surgery is a common complication that can lead to death. We previously reported that the creatinine reduction ratio (CRR) serves as a useful prognostic factor for AKI. The primary objective of this study was to determine the predictors of AKI after surgery. The secondary objective was to determine the reliability of the CRR for short- and long-term outcomes. We retrospectively collected information about cardiac surgery patients who underwent cardiopulmonary bypass. Patients were divided into AKI and non-AKI groups based on the AKIN and RIFLE criteria...

OBJECTIVE: To report long-term functional and oncological outcomes of OPN Methods: We enrolled 182 patients who underwent consecutive OPN with a diagnosis of kidney tumor in our clinic between April 2002 and February 2020 and were selected from our prospective OPN database. Preoperative demographic and clinical characteristics, intraoperative and pathological results, and patients' postoperative functional and oncological follow-up data were retrospectively analyzed. Overall survival (OS) and disease- free survival (DFS) were evaluated using Kaplan-Meier survival analysis...

This Article examines how the rapid deregulation and rampant possession of firearms is likely going to impact policing, and the constitutional law that governs it. For the longest time, lawful gun carry, concealed or open, was exceedingly rare. For a police officer to see a gun was both to see danger, and a crime in progress. This link among guns, danger, and unlawful possession has shaped much of the law of policing. But now, this understanding of the world is in its last stages of unraveling. In nearly all states, guns are no longer unlawful to own and carry by default...

OBJECTIVES: Current infective endocarditis guidelines recommend two different gentamicin synergy dosing strategies for selected Gram-positive organisms. The purpose of this analysis was to evaluate the incidence of acute kidney injury (AKI) with gentamicin synergy dosing, comparing divided-daily and once-daily dosing strategies for infective endocarditis (IE). METHODS: Groups were split into patients who received gentamicin divided-daily dosing and once-daily (3 mg/kg) dosing for Gram-positive IE...

INTRO: The high rates of gun violence in the United States are a recognized public health concern with increased attention since the 1990's. The predominant studies used in gun violence research have been epidemiological approaches and quantitative analyses. This study, instead, examines lived experiences of gunshot wound survivors to better understand their situations. This study also compared the different census categories and their types of gunshot wound injuries. Ethnographic informed analyses may inform public health interventions to decrease firearm injuries...

The appearance of a gunshot wound (GSW) is greatly influenced by the velocity of the projectile, where high-velocity projectiles (HVPs) are defined as ballistic agents reaching a muzzle velocity of > 600 m/s fired from assault rifles. The aim of the study is to present and explain the differences in the dimensions of entrance and exit wounds between the most used handguns and assault rifles and to propose a predictor of HVP, i.e., the ratio of exit and entrance wounds (EX/ENR). The surface area of entrance and exit GSWs and the EX/ENR were calculated...

OBJECTIVES: Partial nephrectomy (PN) is the reference standard for renal mass in a solitary kidney (RMSK), although factors determining functional recovery in this setting remain poorly defined. PATIENTS/METHODS: Single center, retrospective analysis of 841 RMSK patients (1975-2022) managed with PN with functional data, including 361/435/45 with cold/warm/zero ischemia, respectively. A total of 155 of these patients also had necessary studies for detailed analysis of parenchymal volume preserved...

The security of civilians and high-profile officials is of the utmost importance and is often challenging during continuous surveillance carried out by security professionals. Humans have limitations like attention span, distraction, and memory of events which are vulnerabilities of any security system. An automated model that can perform intelligent real-time weapon detection is essential to ensure that such vulnerabilities are prevented from creeping into the system. This will continuously monitor the specified area and alert the security personnel in case of security breaches like the presence of unauthorized armed people...

INTRODUCTION AND IMPORTANCE: Intravascular ballistic embolism is a rare and complex medical condition, posing diagnostic and management challenges. It involves the migration of ballistic materials within the arterial system, often stemming from neck and chest injuries. CASE PRESENTATION: A 13-year-old boy sustained a chest injury from an air rifle, leading to a pellet embolism in the right internal carotid artery, resulting in severe cerebral infarction. Despite intervention attempts, the lodged pellet left the patient with permanent hemiplegia...

BACKGROUND AND IMPORTANCE: Nonpowder firearm injuries to the head pose major health risks, with retained fragments potentially causing harmful sequelae that require neurosurgical intervention. CLINICAL PRESENTATION: We report the case of 2-year-old girl who sustained an accidental gunshot wound to the head. She sustained a penetrating ballistic intracranial injury caused by a BB shot from a rifle. At presentation, she was neurologically intact with a punctate laceration on her left forehead...

The International Tracing Instrument (ITI) is a document adopted by United Nations Member States in 2005, which outlines challenges faced in the tracing of illicit weapons and offers suggestions to increase the success of tracing operations. A key provision of the ITI states that serial numbers must be recoverable if obliterated. This research, therefore, investigates two methods of recovering laser engraved marks on steel, due to the increase in firearms manufacturing relying on lasers to apply critical markings...

IMPORTANCE: Within gun violence research, the types of firearms involved in US school shootings and the origins of these weapons have not been well explored. OBJECTIVE: To examine the type, make, and power of firearms involved in school-related gun violence as well as the sources and methods through which adolescents obtained these weapons. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used descriptive statistics and logistic regression to analyze 253 school shootings executed by 262 adolescents (aged ≤19 years) in the US from January 1, 1990, to December 31, 2016, and to calculate adjusted estimates for missing cases...

BACKGROUND: Acute kidney injury (AKI) after robot-assisted partial nephrectomy (RAPN) is a robust surrogate for chronic kidney disease. The objective of this study was to evaluate the association of ischemia type and duration during RAPN with postoperative AKI. MATERIALS AND METHODS: We reviewed all patients who underwent RAPN at our institution since 2011. The ischemia types were warm ischemia (WI), selective artery clamping (SAC), and zero ischemia (ZI). AKI was defined according to the Risk Injury Failure Loss End-Stage (RIFLE) criteria...

INTRODUCTION: Traumatic embolization of pellets into the cerebral circulation is a rare complication following gunshot wounds to the neck, chest and abdomen. Foreign bodies enter the circulation from early direct puncture or delayed erosion of an artery or vein or directly through the heart. PRESENTATION OF CASE: A previously well 13-year-old Sri Lankan boy who presented 2 h following an air rifle injury to the lower sternum with chest pain, developed seizures and left hemiparesis...

METHODS: The primary predictor variable was the type of firearm...

INTRODUCTION: A lack of sleep can pose a risk during military operations due to the associated decreases in physical and cognitive performance. However, fast-acting ergogenic aids, such as ammonia inhalants (AI), may temporarily mitigate those adverse effects of total sleep deprivation (TSD). Therefore, the present study aimed to investigate the acute effect of AI on cognitive and physical performance throughout 36 hours of TSD in military personnel. METHODS: Eighteen male military cadets (24...

Gun violence in the USA is a documented public health crisis. Publicly accessible data from Twitter posts can be used to rapidly capture and describe the public's recent conversations about guns. Because these gun-related conversations change rapidly, it is important to provide regularly updated information on them. Twitter posts containing gun-related terms were obtained from January 1, 2022 to June 30, 2022. To understand topics of gun-related tweets (N = 449,492), topic modeling was performed with Top2Vec...

INTRODUCTION: Mild traumatic brain injury (mTBI) is prevalent in service members (SMs); however, there is a lack of consensus on the appropriate approach to return to duty (RTD). Head-mounted augmented reality technology, such as the HoloLens 2, can create immersive, salient environments to more effectively evaluate relevant military task performance. The Troop Readiness Evaluation with Augmented Reality Return-to-Duty (READY) platform was developed to objectively quantify cognitive and motor performance during military-specific activities to create a comprehensive approach to aid in mTBI detection and facilitate appropriate RTD...
