BACKGROUND Gender may influence outcomes following traumatic brain injury (TBI) although the mechanism is unknown. Animal TBI studies suggest that gender differences in endogenous hormone production may be the source. Limited retrospective clinical studies on gender present varied conclusions. Pediatric patients represent a unique population as pubescent(More)
The pathophysiological effects of severe sepsis, septic shock and related syndromes result from tissues damaged by the uncontrolled production of the mediators of inflammation. Early deaths are related primarily to the acute effects of the systemic inflammatory response. Later deaths are related more closely to the consequences of multiple organ(More)
The new oxazolidinone antimicrobial, linezolid, has been approved for the treatment of infections caused by various gram-positive bacteria, including meticillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Although instances of linezolid resistance in VRE have been reported, resistance has not been encountered among(More)
HYPOTHESIS Discrepancies exist in complications and outcomes at teaching trauma centers (TTCs) vs nonteaching TCs (NTCs). DESIGN Retrospective review of the National Trauma Data Bank research data sets (January 1, 2007, through December 31, 2008). SETTING Level II TCs. PATIENTS Patients at TTCs were compared with patients at NTCs using demographic,(More)
BACKGROUND Although avoiding hypotension is a primary focus after trauma, elevated systolic blood pressure (SBP) is frequently disregarded. The purpose of this study was to determine the association between elevated admission SBP and delayed outcomes after trauma. METHODS The Los Angeles County Trauma System Database was queried for all patients between(More)
BACKGROUND Prehospital hypothermia (PH) is known to increase mortality following traumatic injury. PH relationship with transfusion requirements has not been documented. The purpose of this investigation was to analyze the impact of PH on blood product requirements and subsequent outcomes. METHODS The Los Angeles County Trauma System Database was queried(More)
BACKGROUND Increasing evidence suggests that the spleen harbors stem cells that act as precursors to insulin-producing pancreas cells. Additionally, small studies with short-term follow-up associate splenectomy with increased rates of diabetes mellitus. The purpose of this study was to analyze the long-term effect of trauma splenectomy on blood glucose. (More)
Previous investigations suggest outcome differences at Level I and Level II trauma centers. We examined use of intracranial pressure (ICP) monitors at Level I and Level II trauma centers after traumatic brain injury (TBI) and its effect on mortality. The 2007 to 2008 National Trauma Databank was reviewed for patients with an indication for ICP monitoring(More)
