Domestic violence is the most common cause of nonfatal injury to women in United States. To identify risk factors for such injuries, we examined socioeconomic and behavioral characteristics who were victims domestic men injured them.
Study objectiveThe goals of this study were to determine the current and projected supply in 2030 contributors emergency care, including residency-trained board-certified physicians, other nurse practitioners, physician assistants. In addition, was designed demand for residency-trained, physicians.MethodsTo forecast future workforce demand, sources existing data used, assumptions based on past potential trends determined, a sensitivity analysis conducted how final would be subject variance...
To determine the prevalence and risk factors associated with motor vehicle collisions (MVCs) near-crashes as reported by emergency medicine (EM) residents following various ED shifts.A survey was sent to all allopathic EM-2-EM-4 in May 1996 asking whether they had ever been involved an MVC or near-crash while driving home after shift. The residents' night shift schedules, self-reported tolerance of work, ability overcome drowsiness, sleep flexibility, morningness/eveningness tendencies also...
Objective While it is known that motor vehicle crash (MVC) fatality rates are inversely related to population density, there has been no description of which variables density. The purpose this study was describe characteristics fatal MVCs and determine Design This a retrospective review accident reporting system (FARS) records. They represent four different density regions over 5-year period in four-state midwest region. Results There were 10,932 people 6,318 vehicles who involved 4,970...
Background: Motor vehicle crash (MVC) mortality rates are inversely related to population density. The purpose of this study was analyze if there is a regional variation in the risk MVC death after controlling for injury severity. Methods: utilized Crash Outcome Data Evaluation System (CODES) data set Nebraska. All fatal or injury-related crashes during 4-year period (1996 through 1999) were analyzed. Injury Severity Scores (ISSs) calculated from CODES listed International Classification...
Distracted driving is an increasingly deadly threat to road safety. This study documents trends in and characteristics of pedestrian, bicycle rider, other victim deaths caused by distracted drivers on U.S. public roads.We obtained data from the Fatality Analysis Reporting System database 2005 2010 every crash that resulted at least one fatality within 30 days occurring roads Following definition used National Highway Traffic Safety Administration, we identified based whether police...
Extremity injuries with hemorrhage have been a significant cause of death in civilian medicine and on the battlefield. The use tourniquet as an intervention is necessary for treatment to injured limb; however, subsequent release results serious acute ischemia-reperfusion (IR) injury skeletal muscle neuromuscular junction (NMJ). Much evidence demonstrates that inflammation important factor IR injury. To find effective therapeutic interventions tourniquet-induced injuries, our current study...
Our previous study has reported that superoxide mediates ischemia-reperfusion (IR)-induced necrosis in mouse skeletal muscle. However, it remains poorly understood whether IR induces apoptosis and what factors are involved IR-induced Using a murine model of tourniquet-induced hindlimb IR, we investigated the relationship between mitochondrial dysfunction Hindlimbs C57/BL6 mice were subjected to 3 h ischemia 4 reperfusion via placement release rubber tourniquet at greater trochanter. Compared...
Chronic heart failure (CHF) is characterized by decreased cardiac parasympathetic and increased sympathetic nerve activity. This autonomic imbalance increases the risk of arrhythmias sudden death in patients with CHF. We hypothesized that molecular cellular alterations postganglionic (CPP) neurons located intracardiac ganglia (CPS) stellate (SG) possibly link to Rat CHF was induced left coronary artery ligation. Single-cell real-time PCR immunofluorescent data showed L (Ca v 1.2 Ca 1.3), P/Q...
Tourniquet application and its subsequent release cause serious injuries to the skeletal muscle, nerve, neuromuscular junction (NMJ) due mechanical compression ischemia-reperfusion (IR). Monitoring structural functional repair of NMJ, muscle after tourniquet-induced is beneficial in exploring potential cellular molecular mechanisms responsible for injuries, establishing effective therapeutic interventions. Here, we observed long-term morphological changes NMJ a murine model hindlimb...
In 2013, milestone ratings became a reporting requirement for emergency medicine (EM) residency programs. Programs rate each resident in the fall and spring on 23 subcompetencies.This study examined incidence of straight line scoring (SLS) EM Milestone ratings, defined as being assessed same score across descriptive analysis measured frequencies SLS all Accreditation Council Graduate Medical Education (ACGME)-accredited programs during 2015-2016 academic year. Outcomes were frequency...
Objective: To determine the frequency and potential predictors of opioid toxicity recurrence after a response to naloxone in adult Emergency Department patients. Methods: A retrospective case-control study naloxone-treated patients with over an 8-year period. Both patient was determined by expert Delphi Panel. The compared duration effect, route exposure, presence other CNS depressant drugs. Results: Ninety 221 (41%) cases discharge diagnosis were treated naloxone; six excluded because lack...
Abstract. Objective: To determine whether male victims of domestic violence have similar rates perpetration compared with men evaluated in the ED other causes injury. Methods: Case‐control retrospective record review linkage to police department records. Cases were identified by ICD code N‐code 995.81 (adult maltreatment syndrome) over a 4‐year period (January 1, 1991, December 31, 1994) at one urban trauma center. Medical records reviewed confirm that assailant was an intimate female...
ongoing efforts to improve access emergency care and department (ED) staffing would benefit from a better understanding of the distribution EDs in United States by size location. This article describes U.S. ED visit volumes according urban versus rural status.the authors used 2007 National Emergency Department Inventories (NEDI)-USA database identify all nonfederal hospitals with their annual volumes. One twelve 2003 Urban Influence Codes was applied each location based on its county. These...
Although dysfunction of arterial baroreflex occurs in human and animal models type-1 diabetes (T1D), the mechanisms involved impairment still remain unclear. The nodose ganglion (NG) contains cell bodies aortic baroreceptor (AB) neurons. Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are expressed AB neurons play an important role regulating excitability. We investigated whether excitability is depressed streptozotocin (STZ)-induced T1D rats HCN this depression.Using...
