To elucidate the predictive capability of shock index (SI), modified SI (MSI), and age SI for mortality in patients assigned to Emergency Severity Index (ESI) level 3 patients. ⋯ In ESI level 3 patients, age SI and SBP showed to be better than SI or MSI in predicting mortality. However, because their predictive capability was modest, age SI or SBP should be considered adjuncts to sort actions in favor of patients with higher risk for mortality.

The current study was designed to evaluate the expression of the second C5a receptor (C5a2) on polymorphonuclear neutrophil and in the cytoplasm of polymorphonuclear neutrophils (C5a2intra) in patients with sepsis in the emergency department (ED) for risk stratification and mortality. ⋯ The C5a2 and the C5a2intra/C5a2 ratio levels are probably valuable for the risk stratification of sepsis and are associated with the mortality of early sepsis in the ED.

The widespread application of tourniquets has reduced battlefield mortality related to extremity exsanguinations. Tourniquet-induced ischemia-reperfusion injury (I/R) can contribute to muscle loss. Postischemic conditioning (PostC) confers protection against I/R in cardiac muscle and skeletal muscle flaps. The objective of this study was to determine the effect of PostC on extremity muscle viability in an established rat hindlimb tourniquet model. ⋯ These negative findings are pertinent as the military investigates different strategies to extend the safe time for tourniquet application.
