RESUMO
For elite athletes who exercise at a high level, sleep is critical to overall health. Many studies have documented the effects of sleep deprivation in the general population, but few studies exist regarding specific effects in the athlete. This review summarizes the effects of sleep deprivation and sleep extension on athletic performance, including reaction time, accuracy, strength and endurance, and cognitive function. There are clear negative effects of sleep deprivation on performance, including reaction time, accuracy, vigor, submaximal strength, and endurance. Cognitive functions such as judgment and decision-making also suffer. Sleep extension can positively affect reaction times, mood, sprint times, tennis serve accuracy, swim turns, kick stroke efficiency, and increased free throw and 3-point accuracy. Banking sleep (sleep extension prior to night of intentional sleep deprivation before sporting event) is a new concept that may also improve performance. For sports medicine providers, the negative effects of sleep deprivation cannot be overstated to athletes. To battle sleep deprivation, athletes may seek supplements with potentially serious side effects; improving sleep quality however is simple and effective, benefiting not only athlete health but also athletic performance.

Tart cherry (TC) juice has many antioxidant and anti-inflammatory polyphenol compounds. TC lessens pain and accelerates strength recovery after exercise and decreases blood markers of inflammation/oxidative stress. These improvements occur in both strength and endurance exercise. TC supplementation may not be optimal during the adaptation/build stage of training. However, excessive inflammatory/oxidative stress during single-day intense training/competition or multiday tournaments may delay return to peak form. In this stage, where recovery (not adaptation) is the priority, TC may be beneficial. Timing and dosage vary widely, but most studies use 8 to 12 oz (1 oz if concentrate form) twice a day, 4- to 5-d loading phase before the event, and 2 to 3 d after to promote recovery. Therefore, for an athlete who has already peaked in training and looking to improve recovery and faster return to competition, TC may be beneficial.

Introduction Despite the prevalence of corticosteroid injections in athletes, little is known about their efficacy in triathletes. We aim to assess attitudes, use, subjective effectiveness, and time to return to sport with corticosteroid injections compared to alternative methods in triathletes with knee pain. Methods This is an observational study during the COVID-19 pandemic. Triathletes answered a 13-question survey posted to three triathlon-specific websites. Results Sixty-one triathletes responded, 97% of whom experienced knee pain at some point in their triathlete career; 63% with knee pain received a corticosteroid injection as treatment (average age 51 years old). The most popular attitude (44.3%) regarding corticosteroid injections was "tried them, with good improvement". Most found the cortisone injection helpful for two to three months (28.6%), or more than one year (28.6%); of individuals who found the injections useful for more than one year, four-eight (50%) had received multiple injections during that same period. After injection, 80.6% returned to sport within one month. The average age of people using alternative treatment methods was 39 years old; most returned to sport within one month (73.7%). Compared to alternative methods, there was an ~80% higher odds of returning to sport within one month using corticosteroid injections; however, this relationship was not significant (OR=1.786, p=0.480, 95% CI:0.448-7.09). Conclusion This is the first study to examine corticosteroid use in triathletes. Corticosteroid use is more common in older triathletes and results in subjective pain improvement. A strong association does not exist for a quicker return to sport using corticosteroid injections compared to alternative methods. Triathletes should be counseled on the timing of injections, duration of side effects, and be aware of potential risks.
RESUMO
An 84-yr-old man presented with right posterior shoulder pain and growing mass. Shoulder range of motion was limited in forward elevation and abduction; result of the neurologic testing was normal. Radiologic workup showed an irregular mass resembling Paget's disease or sarcoma. On surgical inspection, a 16-cm hemorrhagic mass, occupying the entire scapula, was identified. Patient underwent tumor resection and scapulectomy. Postoperatively, he started a rehabilitation program. With attempted ambulation, patient exhibited strong tendencies to lean rightward, walked in circles, and risking fall. The gait abnormality could not be corrected and acute inpatient rehabilitation admission was recommended. A unique rehabilitation program was developed to correct gait deviation, improve balance, and compensate for deficits. After a comprehensive inpatient rehabilitation, the patient was successfully discharged home. We present a review of scapulectomy, postoperative care, and a recommended rehabilitation program.
