OBJECT Up to 16% of children in the US between the ages of 3 and 17 years have either attention deficit-spectrum disorder or a learning disability (LD). Sports-related concussions among youth athletes represent a significant public health concern, and neurocognitive testing is a method to evaluate the severity of cognitive impairment and recovery after a(More)
BACKGROUND The epidemiology of sports-related concussion (SRC) among student-athletes has been extensively researched. However, recent data at the collegiate level are limited. PURPOSE To describe the epidemiology of SRC in 25 National Collegiate Athletic Association (NCAA) sports. STUDY DESIGN Descriptive epidemiology study. METHODS SRC data from the(More)
BACKGROUND Sports-related concussions (SRC) among high school and collegiate athletes represent a significant public health concern. The Concussion in Sport Group (CIS) recommended greater caution regarding return to play with children and adolescents. We hypothesized that younger athletes would take longer to return to neurocognitive baseline than older(More)
OBJECT Several studies have suggested a gender difference in response to sports-related concussion (SRC). The Concussion in Sport group did not include gender as a modifying factor in SRC, concluding that the evidence at that point was equivocal. In the present study the authors endeavored to assess acute neurocognitive and symptom responses to an SRC in(More)
BACKGROUND Limited data exist among collegiate student-athletes on the epidemiology of sports-related concussion (SRC) outcomes, such as symptoms, symptom resolution time, and return-to-play time. PURPOSE This study used the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) to describe the epidemiology of SRC outcomes in 25(More)
BACKGROUND The impact of perioperative hyperglycemia in orthopaedic surgery is not well defined. We hypothesized that hyperglycemia is an independent risk factor for thirty-day surgical-site infection in orthopaedic trauma patients without a history of diabetes at hospital admission. METHODS Patients eighteen years of age or older with isolated(More)
BACKGROUND Delivery of intravenous antibiotic prophylaxis within one hour prior to surgical incision is considered important in helping to decrease the incidence of surgical site infections, but methods to ensure compliance have not been established. METHODS All patients at our institution are subjected to a surgical "time-out" protocol to prevent(More)
OBJECT Sport-related concussions (SRCs) among youth athletes represent a significant public health concern. Prior research suggests that females fare worse symptomatically after an SRC. The authors aimed to assess sex differences in number, severity, and resolution of postconcussive symptoms using reliable change index (RCI) methodology applied to days to(More)
BACKGROUND CONTEXT Given the unsustainable costs of the US health-care system, health-care purchasers, payers, and hospital systems are adopting the concept of value-based purchasing by shifting care away from low-quality providers or hospitals. Legislation now allows public reporting of these quality rankings. True measures of quality, such as surgical(More)
OBJECT Symptomatic intracranial atherosclerotic disease (ICAD) has a high risk of recurrent stroke. Genetic polymorphisms in CYP2C19 and CES1 are associated with adverse outcomes in cardiovascular patients, but have not been studied in ICAD. The authors studied CYP2C19 and CES1 single-nucleotide polymorphisms (SNPs) in symptomatic ICAD patients. METHODS(More)
