This paper shows that extraction and analysis of various acoustic features from speech using mobile devices can allow the detection of patterns that could be indicative of neurological trauma. This may pave the way for new types of biomarkers and diagnostic tools. Toward this end, we created a mobile application designed to diagnose mild traumatic brain injuries (mTBI) such as concussions. Using this application, data was collected from youth athletes from 47 high schools and colleges in the the Midwestern United States...

The notion that prolonged, intense exercise causes an 'open window' of immunodepression during recovery after exercise is well accepted. Repeated exercise bouts or intensified training without sufficient recovery may increase the risk of illness. However, except for salivary IgA, clear and consistent markers of this immunodepression remain elusive. Exercise increases circulating neutrophil and monocyte counts, and reduces circulating lymphocyte count during recovery. This lymphopenia results from preferential egress of lymphocyte subtypes with potent effector functions (e...

BACKGROUND: Hip fracture occurs predominantly in older people, many of whom are frail and undernourished. After hip fracture surgery and rehabilitation, most patients experience a decline in mobility and function. Anabolic steroids, the synthetic derivatives of the male hormone testosterone, have been used in combination with exercise to improve muscle mass and strength in athletes. They may have similar effects in older people who are recovering from hip fracture. OBJECTIVES: To examine the effects (primarily in terms of functional outcome and adverse events) of anabolic steroids after surgical treatment of hip fracture in older people...

BACKGROUND: Musculoskeletal conditions involving the shoulder are common and, because of the importance of the upper limb and hand in daily function, symptoms in this region are commonly associated with functional impairment in athletic and non-athletic populations. Deriving a definitive diagnosis as to the cause of shoulder symptoms is fraught with difficulty. Limitations have been recognised for imaging and for orthopaedic special tests. 1 solution is to partially base management on the response to tests aimed at reducing the severity of the patient's perception of symptoms...
