PURPOSE: Ultrasound tissue characterization (UTC) is an imaging tool used to quantify tendon structural integrity. UTC has quantified Achilles tendon (AT) acute response to load in athletes; however, AT response to cumulative load over a season is unknown. The purpose of this study was to evaluate AT response across a 4-month competitive season in collegiate cross-country (XC) runners. METHODS: Participants (n=21; male=9, female=12; age=19.8±1.2yrs; height=171...

Helmeted impact devices have allowed researchers to investigate the biomechanics of head impacts in vivo. While increased impact magnitude has been associated with greater concussion risk, a definitive concussive threshold has not been established. It is likely that concussion risk is not determined by a single impact itself, but a host of predisposing factors. These factors may include genetics, fatigue, and/or prior head impact exposure. The objective of the current paper is to investigate the association between cumulative head impact magnitude and concussion risk...

PURPOSE: Diffuse alveolar hemorrhage (DAH) with negative-pressure pulmonary edema (NPPE) is an uncommon yet life-threatening condition. We aimed at describing the circumstances, clinical, radiological, and bronchoscopic features, as well as the outcome of patients with NPPE-related DAH. METHODS: We performed a retrospective, observational cohort study, using data prospectively collected over 35 years in an intensive care unit (ICU). RESULTS: Of the 149 patients admitted for DAH, we identified 18 NPPE episodes in 15 patients, one admitted four times for recurrent NPPE-related DAH...

BACKGROUND: Prolonged endurance exercise is known to cause elevation of cardiac troponin I (cTnI). Previous studies have reported the correlation of several factors with exercise-induced cTnI release. However, the investigation of the predictors for elevated cTnI and postrace kinetics of cTnI after ultramarathon running is lacking, especially in an Oriental population. METHODS: Twenty-six participants, including eight hepatitis B virus carrier (HBVc) runners, who finished a 100-km ultramarathon in Taiwan were enrolled...

BACKGROUND: Approximately 3.8 million sport and recreational concussions occur per year, creating a need for accurate diagnosis and management of concussions. Researchers and clinicians are exploring the potential dose-response cumulative effects of concussive injuries using computerized neuropsychological exams, however, results have been mixed and/or contradictory. This study starts with a large adolescent population and applies strict inclusion criteria to examine how previous mild traumatic brain injuries affect symptom reports and neurocognitive performance on the Immediate Post-concussion Assessment and Cognitive Testing (ImPACT) computerized tool...

This column describes the approaches taken by librarians and staff at James Madison University (JMU) Libraries & Educational Technologies (LET) to extend library support to university athletics. The model resembles that used for outreach to academic programs and was first adapted to the semi-clinical, nonacademic Strength & Conditioning Department, then to JMU Athletics as a whole. Librarians offered targeted instructional sessions, orientations, and asynchronous learning modules embedded in the learning management system...

BACKGROUND: Heterotopic ossification (HO) is a well-known complication following the surgical treatment of fractures and dislocations about the elbow but it is not commonly discussed as a complication following arthroscopy. We present a case of a young athlete who developed HO after the arthroscopic treatment of lateral epicondylitis. METHODS: This is a case report chart review of a 24 year old male with lateral epicondylitis. After failing conservative measures, arthroscopic debridement of the extensor carpi radialis brevis (ECRB) origin ensued...

BACKGROUND: Skeletal muscle injuries are the most common sports-related injury and a major concern in sports medicine. The effect of platelet-rich plasma (PRP) injections on muscle healing is still poorly understood, and current data are inconclusive. PURPOSE: To evaluate the effects of an ultrasound-guided intramuscular PRP injection, administered 24 hours after injury, and/or posttraumatic daily exercise training for 2 weeks on skeletal muscle healing in a recently established rat model of skeletal muscle injury that highly mimics the muscle trauma seen in human athletes...

BACKGROUND: Osteonecrosis of the hips and knees is an often debilitating adverse event in children treated with glucocorticoids for leukemia and lymphoma but the impact of shoulder involvement has been understudied. Thus, we investigated the severity and functional impairment of shoulder osteonecrosis in a well-characterized population of pediatric patients treated for acute lymphoblastic leukemia or lymphoma. METHODS: We retrospectively reviewed orthopaedic clinic and physical therapy evaluations to determine range of motion (ROM), pain, and impact of magnetic resonance-defined osteonecrosis (ON) on activities of daily living...

CONTEXT: Sudden cardiac death (SCD) in a young athlete is a tragic event and is the leading medical cause of death in this population. The precise incidence of SCD in young athletes has been subject of debate, with studies reporting drastically different rates (1:917,000 athlete-years (AYs) to 1:3000 AYs) depending on the methodological design of the investigation or the targeted population. EVIDENCE ACQUISITION: A literature search was performed in PubMed using the terms: incidence, sudden cardiac death, sudden death, sudden cardiac arrest, etiology, pathology, registry, athlete, young, children, and adolescents...

BACKGROUND: There is a growing awareness of the importance of mental health care in National Collegiate Athletic Association (NCAA) student-athletes; however, there is a lack of literature on mental health resources in collegiate settings. Identifying current practices can set the stage to improve the delivery of care. HYPOTHESIS: There is great variability in resources and current practices and no "standard of care" exists.

This study examined the feasibility of Enzogenol® as a potential treatment modality for concussed individuals with residual symptoms in the chronic phase. Forty-two student-athletes with history of sport-related concussion were enrolled, comparing Enzogenol® versus placebo. Testing was conducted using virtual reality (VR) and electroencephalography (EEG), with neuropsychological (NP) tasks primarily used to induce cognitive challenges. After six weeks, the Enzogenol® group showed enhanced frontal-midline theta, and decreased parietal theta power, indicating reduced mental fatigue...

Athletes occasionally attempt to lower their baseline scores to mask the effects of a concussion during post-trauma assessment, a phenomenon known as sandbagging. In order to help prevent this from occurring, the Rey Dot Counting Test (DCT) was examined as a potential measure to be added to a Division II university screening battery. Investigators utilized samples of athletes at baseline and non-athlete students instructed to provide honest effort or suppressed effort, either naïvely or coached. The results support the use of the DCT as a valid measure of suboptimal performance when using modified norms established from collegiate populations...

Investigating short-term effects of subconcussive impacts on neurocognitive functioning, we employed a repeated measures multivariate model and regression-based measure to examine neurocognitive changes in 771 contact and noncontact high school athletes over a two-year period. Results reveal significant changes in Visual Motor Speed for both groups over a two-year period, with small effect sizes. According to regression-based measures, differences in contact sport athletes' expected Time 2 performances were significant for Visual Motor Speed, also with minimal effects...

We investigated the relationship between performance-related anxiety and the neural response to errors. Using the sport anxiety scale, we selected university athletes high in sports anxiety and low in sports anxiety. The two groups performed a spatial Stroop task while their performance was being evaluated by an experimenter and also during a control (i.e., no evaluation) condition. The error-related negativity was significantly larger during the evaluation than control condition among athletes who reported high performance-related anxiety...
