Randomized Controlled Trial Comparative Study
A Randomized Controlled Trial of Aspirin and Exertional Heat Stress Activation of Platelets in Firefighters during Exertion in Thermal Protective Clothing.
Platelet aggregation is enhanced in firefighters following short bouts of work in thermal protective clothing (TPC). We sought to determine if aspirin therapy before and/or following exertion in TPC prevents platelet activation. ⋯ Daily aspirin therapy blunts platelet activation during exertional heat stress and single-dose aspirin therapy following exertional heat stress reduces platelet activation within 60 minutes.

Randomized Controlled Trial Comparative Study
Randomized Trial Comparing Two Mass Casualty Triage Systems (JumpSTART versus SALT) in a Pediatric Simulated Mass Casualty Event.
Several field triage systems have been developed to rapidly sort patients following a mass casualty incident (MCI). JumpSTART (Simple Triage and Rapid Transport) is a pediatric-specific MCI triage system. SALT (Sort, Assess, Lifesaving interventions, Treat/Transport) has been proposed as a new national standard for MCI triage for both adult and pediatric patients, but it has not been tested in a pediatric population. This pilot study hypothesizes that SALT is at least as good as JumpSTART in triage accuracy, speed, and ease of use in a simulated pediatric MCI. ⋯ SALT appears to be at least as good as JumpSTART in overall triage accuracy, overtriage, or undertriage rates in a simulated pediatric MCI. Both systems were considered easy to use. However, JumpSTART was 8 seconds faster per patient in time taken to assign triage designations.

To determine whether emergency physicians (EPs) and prehospital emergency medical services (EMS) personnel differ in their assessment of motor vehicle crash (MVC) severity and the potential for serious injury when viewing crash scene photographs. ⋯ Although overall agreement between EPs and EMS personnel was excellent, differences in estimation of crash severity and potential for injury were identified among crashes estimated to be moderate in severity.

Case Reports
Acute Coronary Ischemia Identified by EMS Providers in a Standing Middle-aged Male with Atypical Symptoms.
Acute coronary syndrome and myocardial infarction have been described to present with atypical symptoms in certain subsets of patients. However, these subsets commonly do not include middle-aged males with a paucity of underlying medical conditions. ⋯ Further, electrocardiographic changes consistent with acute ischemia could only be demonstrated with the patient in a standing position, prior to the development of an occurrence of ventricular tachycardia, which degenerated into ventricular fibrillation. To our knowledge, this is a very rare case of electrocardiographic changes consistent with occult, acute cardiac ischemia with a proven coronary artery lesion seen initially only with the patient in a standing position.

Observational Study
Pre-resuscitation Lactate and Hospital Mortality in Prehospital Patients.
Serum lactate elevations are associated with morbidity and mortality in trauma patients, but their value in prehospital medical patients prior to resuscitation is unknown. We sought to assess the distribution of blood lactate concentrations prior to intravenous (i.v.) resuscitation and examine the association of elevation on in-hospital death. ⋯ Initial lactate concentration in our prehospital medical patient population was associated with hospital mortality. However, it is a modest predictor of outcome, offering similar discrimination to a prehospital critical illness score.
