Comparative Study
Retrospective Evaluation of Venous Thromboembolism Prophylaxis in Elderly, High-Risk Trauma Patients.
Venous thromboembolism (VTE) risk increases with age. Scarce data exist for patients age ≥65 y. This study evaluated VTE incidence in elderly, high-risk trauma patients receiving unfractionated heparin (UFH) or enoxaparin chemoprophylaxis. ⋯ VTE incidence may be similar for high-risk, elderly trauma patients receiving UFH and enoxaparin chemoprophylaxis. Further research is necessary to determine noninferiority of UFH to enoxaparin in this patient population.

Trauma is the leading cause of death in pediatric patients over 1 y of age. Controversy exists regarding prehospital airway management for these patients, with some studies suggesting that endotracheal intubation in the field or at a referring hospital is associated with increased mortality and complication rate. These studies were largely performed at urban centers, and it is unclear whether the results apply to suburban/rural networks with longer transport times and more stops at referring hospitals. The purpose of this study is to evaluate differential outcomes in pediatric trauma patients who underwent endotracheal intubation at the scene of injury, referring hospital, or pediatric trauma center in a predominantly rural/suburban setting. ⋯ Mortality and duration of intubation were lowest in trauma patients intubated at a pediatric trauma center. However, location of intubation was not a significant independent predictor of mortality or complications on multivariate analysis, suggesting that age, injury severity, and neurologic status are the main indicators of prognosis in severe pediatric trauma.

Observational Study
Impact of Injury Severity on the Inflammatory State and Severe Anemia.
Severe traumatic injury is a major cause of morbidity and mortality. Our goal was to analyze blunt traumatic injury by injury severity score (ISS) and compare with elective hip repair, as a transient injury, and healthy control with the hypothesis that more severe injury would lead to an increase in neuroendocrine activation, systemic inflammation, and worse anemia. ⋯ Increased neuroendocrine activation, systemic inflammation, and anemia correlated with worsening injury severity, lower age, and increased pRBC transfusions. Elective hip replacement patients have only minimal systemic inflammation with an appropriate bone marrow response to anemia. This study demonstrates a link between injury severity, neuroendocrine activation, systemic inflammation, and the bone marrow response to anemia.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) and Abdominal Aortic and Junctional Tourniquet (AAJT) have received much attention in recent as methods for temporary control of junctional hemorrhage. Previous studies typically used the animal's shed blood for resuscitation. With current interest in moving REBOA to prehospital environment, this study aimed to evaluate the hemodynamic and metabolic responses to different resuscitation fluids used with these devices. ⋯ After 60 min, infrarenal REBOA or AAJT aortic occlusion SWB and FFP resuscitation provided better blood pressure support with half of the resuscitative volume of PlasmaLyte. Swine resuscitated with SWB and FFP also had a more favorable coagulation profile. These data suggest that whole blood or component therapy should be used for resuscitation in conjunction with REBOA or AAJT, and administration of these fluids should be considered if prehospital device use is pursued.

Women remain under-represented in academic surgery despite increasing percentages of female surgeons and surgery residents. Publications and leadership positions are used for hiring and promoting academic surgeons. We sought to determine the disparity of female authorship when compared with male authors in surgical peer-reviewed publications. ⋯ Women surgeons publish research at a rate proportional to the number of females involved in that specialty. Disparities in leadership roles are unlikely explained by differences in publications. Instead, disparities are likely due to other reasons such as failure to attract women to academic surgery and failure to promote and mentor women surgeons into leadership positions.
