Objective: Continued play following concussion can lead to worse outcomes and longer recoveries compared with athletes who immediately report. This has been well documented in youth athletes, while less attention has been paid to collegiate athletes despite differences in healthcare access, recovery trajectories, and additional pressures to play. Therefore, the purpose of this study was to determine if continuing to play immediately following a concussion influenced clinical outcomes and recovery time in collegiate athletes.

Early cardiac surgery in neonates and infants with congenital heart disease has been performed since the middle to late years of the twentieth century. To date, there are very few reports of successful congenital heart surgery using cardiopulmonary bypass (CPB) in premature babies less than 1000 g with serious congenital heart disease. Limited information is available in the literature describing perfusion techniques for this extremely fragile patient population.

Context: Injury or illness can affect individual perceptions of health status and health-related quality of life (HRQOL). Concussion can result in different symptoms, impairments, and functional limitations that have been found to lower HRQOL. Furthermore, concussion is known to influence the emotional and behavioral dyscontrol domains of HRQOL in pediatric populations; however, this has yet to be explored in other populations.

Objective: Prior psychometric research has identified symptom subscales for the Post-Concussion Symptom Scale (PCSS) based on confirmatory factor analysis (CFA), including cognitive, physical, sleep-arousal, and affective symptom factors. Study objectives included: (1) replicate the 4-factor PCSS model in a diverse sample of athletes with concussion, (2) test the model for invariance across race, gender, and competitive level, and (3) compare symptom subscale and total symptom scores across concussed groups with established invariance.

Setting: Three regional concussion care centers.

Athletic identity is a psychological factor of concern for athletes after sport-related concussion (SRC). The integrated model of response to sport injury includes athletic identity as a psychological factor within its model, but it has often been overlooked as a consideration affecting outcomes of SRC. In this review, we applied the integrated model of response to sport injury to the current available evidence about the negative consequences of a stronger athletic identity on health outcomes after SRC.

Although visual symptoms are common following concussion, quantitative measures of visual function are missing from concussion evaluation protocols on the athletic sideline. For the past half century, rapid automatized naming (RAN) tasks have demonstrated promise as quantitative neuro-visual assessment tools in the setting of head trauma and other disorders but have been previously limited in accessibility and scalability. The Mobile Interactive Cognitive Kit (MICK) App is a digital RAN test that can be downloaded on most mobile devices and can therefore provide a quantitative measure of visual function anywhere, including the athletic sideline.

Prior work has reported that the declines observed in body mass index (BMI) and circumference measurements in their cross-sectional data were twice as large when calculated from distance energy expenditure estimations compared to energy expenditure estimations based on time and intensity. The primary purpose of this study was to compare walking/running for distance to walking/running for time as part of an exercise intervention. This study followed a between-subjects, repeated measures design.

Article Synopsis
  • The study aimed to create regression equations that estimate appendicular fat-free adipose tissue (FFAT) from a single ultrasound image of the forearm in older Japanese adults, aged 60 to 79.
  • Researchers divided 311 subjects into two groups for model development and cross-validation, using DXA scans and ultrasound measurements of body composition.
  • Results showed a strong correlation between the ultrasound predictions and DXA measurements of aLM-minus-FFAT, suggesting that the ultrasound method is a valid alternative for assessing body composition in older adults.

It is unknown whether age-related site-specific muscle loss is associated with areal bone mineral density (aBMD) in older adults. To examine the relationships between aBMD and whole-body muscle thickness distribution, 97 healthy adults (46 women and 51 men) aged 50-78 years volunteered. Total and appendicular lean soft tissue mass, aBMD of the lumbar spine (LS-aBMD) and femoral neck (FN-aBMD) were determined using dual-energy X-ray absorptiometry.
