There are 5000-10,000 snake envenomations annually in the United States. Fortunately, few are fatal. In this study we review the epidemiology of fatal snakebites. ⋯ Death following envenomation from a native U.S. snake is unlikely, particularly if medical attention is sought promptly. Rattlesnake envenomations are more likely to be fatal than bites from other species. Intentionally engaging with a venomous snake raises the risk of incurring a fatal bite, as does concurrent alcohol or drug use. Age less than 12 years old does not appear to be a risk factor for a fatal outcome, while elderly patients may have a slightly increased risk of death.

Little is known about the role of gender in the dual biomarker strategy using copeptin and troponin for the early rule-out of non-ST-elevation myocardial infarction (NSTEMI). We aimed to evaluate gender-based differences on copeptin levels, combined negative predictive value (NPV) and predictors of copeptin elevation at admission. ⋯ Men with suspected NSTEMI have higher copeptin levels. The dual biomarker rule-out strategy has a similar performance in both male and female patients. Certain predictors of copeptin elevation are gender-specific.

Mortality for out-of-hospital cardiac arrest is high when traditional chest compressions are used without adjuncts. The abdominal aortic and junctional tourniquet (AAJT) is a device with a wedge-shaped air bladder that occludes the aortic bifurcation, augmenting blood flow to the heart and brain. Previously, the addition of AAJT during chest compression led to an increase in rate of survival in a model of traumatic cardiac arrest. ⋯ The AAJT did not confer a survival advantage during chest compressions, but hemodynamic improvements were observed while the AAJT was in place.

Comparative Study
Comparison of the quick SOFA score with Glasgow-Blatchford and Rockall scores in predicting severity in patients with upper gastrointestinal bleeding.
Upper gastrointestinal bleeding is one of the common causes of mortality and morbidity. The Rockall score (RS) and Glasgow-Blatchford score (GBS) are frequently used in determining the prognosis and predicting in-hospital adverse events, such as mortality, re-bleeding, hospital stay, and blood transfusion requirements. The quick Sepsis Related Organ Failure Assessment (qSOFA) score is easy and swift to calculate. The commonly used scores and the qSOFA score were compared and why and when these scores are most useful was investigated. ⋯ Early use of risk stratification scores in upper gastrointestinal bleeding is important due to the high risk of morbidity and mortality. All scoring systems were effective in predicting mortality, the need for intensive care, and re-bleeding. The GBS had a greater predictive power in terms of mortality and transfusion need, the qSOFA score for intensive care need, and the RS for re-bleeding. The simpler, more efficient, and more easily calculated qSOFA score can be used to estimate the severity of patients with upper gastrointestinal bleeding.
