abstract = {Objective: Baseline, preseason assessment of cognition, symptoms, and balance has been recommended as part of a comprehensive sport concussion management program. We examined the relationship between sleep and baseline test results. We hypothesized that adolescents who slept fewer hours the night before would report more symptoms and perform more poorly on cognitive testing than students who had a full night sleep. Design: Cross-sectional observation study. Setting: Preseason concussion testing for high school athletes. Participants: A large sample (n 2928) of student athletes from Maine, USA, between the ages of 13 and 18 years completed preseason testing. Participants with developmental problems, a history of treatment for neurological or psychiatric problems, recent concussion, or 3 or more prior concussions were excluded. Assessment of Risk Factors: Athletes were divided into 4 groups based on their sleep duration the night before testing. Main Outcome Measures: Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT; ImPACT Applications, Inc, Pittsburgh, PA) cognitive composite scores and the embedded Post-Concussion Symptom Scale. Results: Sleep was not related to any ImPACT cognitive composite score, after covarying for age and controlling for multiple comparisons. In contrast, there were sleep duration, sex, and sleep duration by sex effects on the Post-Concussion Symptom Scale. The effect of sleep duration on symptom reporting was more pronounced in girls. Supplementary analyses suggested that sleep insufficiency was associated with a diverse array of postconcussion-like symptoms. Conclusions: Poor sleep the night before baseline or postinjury testing may be an important confound when assessing postconcussion symptoms. Girls may be more vulnerable to experiencing and reporting symptoms following insufficient sleep. Clinical Relevance: Clinicians should routinely ask how the athlete slept the night before preseason baseline testing and consider deferring the symptom assessment or later retesting athletes who slept poorly.

abstract = {Objective: To estimate the risk of athletes with Chiari malformations sustaining a catastrophic injury. Design: Retrospective, descriptive cohort study. Participants: All patients diagnosed with Chiari malformation at our institution between June 2008 and November 2011. Assessment of Risk Factors: Participants were mailed a questionnaire regarding the number of seasons they participated in organized athletics. Magnetic resonance images were reviewed to describe the characteristics of respondent's Chiari malformations. Main Outcome Measures: Whether or not the patient had sustained an injury resulting in death, coma, or paralysis. Results: We had a 53% (N = 147) response rate. Respondents were of a mean age of 15 years (SD, 2 years) at the time of diagnosis. The mean length of protrusion of the cerebellar tonsils below the foramen magnum was 11.2 mm (SD, 5.7 mm). Most of the respondents had pointed cerebellar tonsils and some degree of crowding within the foramen magnum. During a total of 1627 athletic seasons played by patients with Chiari malformation, 0 respondents [95% confidence interval (CI), 0.0000-0.0023] sustained an injury resulting in death, coma, or paralysis. Likewise, during 191 collision sport athletic seasons, 0 (95% CI, 0.0000-0.0191) respondents sustained an injury resulting in death, coma, or paralysis. Conclusions: The risk of athletes with Chiari malformations suffering catastrophic injuries during sports participation is low. This estimate of risk should be considered when making return-toplay decisions. Given the variability of anatomical consideration for patients with Chiari malformations, however, each return-to-play decision must continue to be made on a case-by-case basis, considering all of the available information. Clinical Relevance: The low risk of athletes with Chiari malformations suffering catastrophic injuries in sports should be considered when making return-to-play decisions. © 2014 Wolters Kluwer Health, Inc.
