Ergothioneine (EGT) is a natural compound that is synthesized by soil bacteria in fungal substrates and exhibits antioxidant functions in many cell models. The purpose of this study was to investigate the effect of EGT on mesenteric ischemia and reperfusion injury. ⋯ EGT attenuates mesenteric ischemia reperfusion injury in rat intestine by increasing tissue HSP-70 and decreasing TNF-alpha, IL-1beta, MDA, and MPO levels. EGT also improves morphological alterations, which occurred after IR injury after prolonged periods of reperfusion.

The majority of early trauma deaths are related to uncontrolled, noncompressible, parenchymal hemorrhage from truncal injuries. The purpose of this study was to formulate a fibrin sealant foam (FSF) able to control severe parenchymal bleeding without compression or vascular control. ⋯ Biological nature, rapid preparation, coverage of large wound areas, and effective hemostatic properties make pressurized FSF an ideal candidate for treating nonoperable parenchymal injuries in damage control procedures.

As severe obesity (BMI >40kg/m(2)) and its surgical treatment rise, primary care physicians (PCPs) will more frequently evaluate, refer, and oversee the long-term medical management of bariatric patients. A cross-sectional mail survey was conducted to assess the attitudes, knowledge, and bariatric referral practices among family and internal medicine physicians in North Carolina. ⋯ Bariatric surgeons will optimize referrals and postoperative care for patients by working cooperatively with PCPs and by providing educational resources.

Thermal injury causes a breakdown in the intestinal mucosal barrier due to ischemia reperfusion injury, which can induce bacterial translocation (BT), sepsis, and multiple organ failure in burn patients. The aim of this study was to investigate the effect of ethyl pyruvate (EP) on intestinal oxidant damage and BT in burn injury. ⋯ Our data suggested that EP can inhibit the BT and myeloperoxidase and malondialdehyde production in intestine following thermal injury, suggesting anti-inflammatory and anti-oxidant properties of EP.

Traditional models of shock classify severity based on the volume of hemorrhage. Clinically, hemorrhage occurs at a variable rate, usually slowing as blood pressure drops; however most animal experimental models use a constant rate of hemorrhage. Our hypothesis was that rapid bleeding followed by slower bleeding using a fixed total volume would result in a greater physiologic insult. ⋯ A more physiologic method of fixed volume hemorrhagic shock results in a significantly increased physiologic response as demonstrated by increased volume of fluid resuscitation. This differential physiologic response may represent an improved hemorrhagic shock model, and could have implications for future hemorrhagic shock studies.
