Outcomes of sport-related concussion among college athletes.

The author collected and analyzed data for all student-athletes diagnosed with concussion between 1998 and 2011. Outcome measurements were post-concussion symptom duration, time interval until return-to-play, and clinical outcomes self-reported by athletes and by athlete's parent/guardian 1 year post-injury. A total of 98 concussions occurred in 95 student athletes among a cohort averaging 350 athletes competing yearly.

Clinical utility of ImPACT assessment for postconcussion return-to-play counseling: psychometric issues.

Computerized neuropsychological testing is commonly utilized in the management of sport-related concussion. In particular, the Immediate Postconcussion Assessment and Cognitive Testing 2.0 program (ImPACT) is widely used to assess the cognitive functioning of athletes before and after a concussion.

Working memory capacity among collegiate student athletes: effects of sport-related head contacts, concussions, and working memory demands.

Objective: To measure working memory capacity among a cohort of collegiate athletes and to compare results between athletes competing in head-contact-prone sports with those not subject to repeated head contacts. A secondary objective was to determine the effect of sport-related concussion on working memory capacity.

Design: Ambidirectional cohort study.

Body art (body piercing and tattooing) among undergraduate university students: "then and now".

Purpose: To survey the prevalence of body art and incidence of medical complications among university students comparing results in 2001 and 2006.

Methods: Students reported body piercings and tattoos and occurrence of medical complications.

Results: Prevalence of body piercing was 51% and tattooing 22%.

Prevalence of body art (body piercing and tattooing) in university undergraduates and incidence of medical complications.

Objectives: To survey the prevalence of body art (body piercing and tattooing) in university undergraduate students and to determine the incidence of medical complications from these procedures.

Subjects And Methods: Between February and May 2001, students were offered the opportunity to complete an anonymous, voluntary survey at the beginning of class or organizational meetings. The survey instrument requested information concerning body piercing and tattooing (current or removed) by body site, age, sex, height, weight, body mass index, undergraduate class, athletic status, and the occurrence of medical complications.
