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 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)
Gram-positive cocci are becoming increasingly resistant to traditionally used antimicrobial agents. Staphylococcus aureus, coagulase-negative staphylococci, the enterococcus, and Streptococcus pneumoniae are the most commonly encountered of such pathogens in clinical practice. Clinicians should be keenly aware of the usual types of infections that are(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)
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)
BACKGROUND In adult trauma, mortality varies with race and insurance status. In the elderly, insurance type has little impact on mortality after trauma and the influence of race is reduced. How race and insurance affect pediatric trauma requires further attention. We hypothesized that mortality after pediatric trauma is influenced by insurance type and not(More)
Traumatic brain injury (TBI) is an enormous public health problem, with 1.7 million new cases of TBI recorded annually by the Centers for Disease Control. However, TBI has proven to be an extremely challenging condition to treat. Here, we apply a nanoprodrug strategy in a mouse model of TBI. The novel nanoprodrug contains a derivative of the nonsteroidal(More)
