Risk of Concussion During Sports Versus Physical Education Among New Mexico Middle and High School Students.

Objectives: To measure the risk of concussion among New Mexico middle and high school students during both sports and physical education.

Methods: Athletic directors or athletic trainers in 147 schools were asked to report the number of concussions occurring during sports and physical education in the 2013 to 2014 school year. We calculated 1-year cumulative incidence rates.

Recovery of Working Memory Following Pediatric Traumatic Brain Injury: A Longitudinal Analysis.

In a prospective longitudinal study, the trajectory of verbal and visual-spatial working memory (WM) development was examined 2-, 6-, 12-, and 24-months following complicated-mild to severe pediatric traumatic brain injury (TBI; n = 55) relative to an orthopedic injury comparison group (n = 47). Individual growth curve modeling revealed an interaction of age, severity, and time for verbal, but not visual-spatial WM. The youngest children with severe TBI had the lowest scores and slowest verbal WM growth.

Does processing speed mediate the effect of pediatric traumatic brain injury on working memory?

Objective: Processing speed (PS) and working memory (WM), core abilities that support learning, are vulnerable to disruption following traumatic brain injury (TBI). Developmental increases in WM are related to age-related changes in PS. The purpose of this study was to investigate whether WM deficits in children with TBI are mediated by PS.

The effects of pediatric traumatic brain injury on verbal and visual-spatial working memory.

The purpose of this study was to investigate the effects of pediatric traumatic brain injury (TBI) on verbal and visual-spatial working memory (WM). WM tasks examined memory span through recall of the last item of a series of stimuli. Additionally, both verbal and visual-spatial tests had a dual-task condition assessing the effect of increasing demands on the central executive (CE).

Extensive small bowel resection in dogs and cats: 20 cases (1998-2004).

Objective: To determine outcome in dogs and cats that underwent extensive (ie, > 50%) resection of the small intestine and identify factors associated with outcome.

Design: Retrospective case series.

Animals: 13 dogs and 7 cats.

Subtotal pericardectomy and epicardial excision for treatment of coccidioidomycosis-induced effusive-constrictive pericarditis in dogs: 17 cases (1999-2003).

Objective: To determine the history, clinicopathologic findings, and results of surgery for effusive-constrictive pericarditis associated with Coccidioides immitis infection in dogs.

Design: Retrospective study.

Animals: 17 client-owned dogs that underwent a subtotal pericardectomy and epicardial excision.

Ultrasound diagnosis: intra-abdominal torsion of a non-neoplastic testicle in a cryptorchid dog.

A 6-month-old male bilaterally cryptorchid Boxer was examined for acute abdominal pain. The results of physical examination, laboratory testing, and ultrasonographic examination are presented. Intra-abdominal testicular torsion was suspected and confirmed at surgery.
