Retrospective analysis of whole-body cryotherapy adverse effects in Division I collegiate athletes.

CONTEXT: Although the physiological effects and the performance of athletes after utilizing whole-body cryotherapy (WBC) have been widely studied, there is a lack of data on its adverse effects. It is important to be aware of the adverse effects of any treatment for its use to be properly recommended. OBJECTIVES: This study aims to provide insight to any adverse effects that collegiate athletes experienced after utilizing WBC to better utilize this therapeutic modality. METHODS: After the Institutional Review Board (IRB) deemed exemption, all 457 Division 1-A varsity athletes were recruited via email to participate in a retrospective survey. Participants consented to the study by continuing to the questions. The inclusion criteria were that they must be 18 years of age or older, had completed WBC at that university, and were a student-athlete. The survey was six questions long, and if any of the inclusion criteria was not met, they were redirected to end the survey. The data were analyzed utilizing odds ratios. RESULTS: Of the 457 student-athletes, 11.2% (n=51) responded and 6.3% (n=29) met the inclusion criteria. Responses were obtained from women's lacrosse (27.6%; n=8), women's gymnastics (24.1%, n=7), field hockey (17.2%, n=5), wrestling (6.9%, n=2), football (6.9%, n=2), women's cross country (3.5%, n=1), men's basketball (3.5%, n=1), women's volleyball (3.5%, n=1), softball (3.5%, n=1), and baseball (3.5%, n=1). Among the responses, 79.3% (n=23) were females and 29.7% (n=6) were males. Within 1 h of WBC, the most frequently reported adverse effects were skin rash (27.6%, n=8), itching (13.8%, n=4), and fatigue (6.9%, n=2). More than 1 h after WBC, the most frequently reported adverse effects were skin rash (20.7%, n=6), itching (10.3%, n=3), and increased energy (6.9%, n=2). When stratified by female and male athletes, for both within 1 h and more than 1 h after WBC, there were increased odds for females reporting adverse effects; however, neither were statistically significant (OR 4.58, p=0.19, 95% CI 0.46 to 45.61) (OR 3.84, p=0.25, 95% CI 0.39 to 38.36). Within 1 h of WBC, 58.6% (n=17) of subjects reported no adverse effects, and more than 1 h after WBC, 65.5% (n=19) subjects reported no adverse effects. The mean satisfaction level rating was 6.34 (range 0-10, n=29). When asked if they would do WBC again, 65.5% (n=19) responded "yes" and 34.5% (n=10) responded "no." CONCLUSIONS: In this collegiate athlete population, negative adverse effects of WBC commonly included skin burns and itching while potentially proving a beneficial adverse effect of increased energy. Subjects commonly reported no adverse effects after WBC treatment as well.

Hair and Occupational Success among Chief Executive Officers in Business.

This study assessed relationship between hair loss and professional success by characterizing severity of hair loss among current white male chief executive officers (CEOs) in the United States. This observational study of androgenic alopecia among business executives was conducted by grading anterior and lateral view photographs of CEOs aged 50-69 years. Blinded, independent two-reviewer assessments of androgenic alopecia were performed based on the Hamilton-Norwood Hair Loss Scale. In all, 68 CEOs were included in this review, with 34 individuals each in the age groups of 50-59 and 60-69 years. Significant hair loss occurred in 18% (6/34) of the CEOs aged 50-59 years and in 35% (12/34) of those aged 60-69 years. The findings of the study established that among white male CEOs aged 50-69 years, significant hair loss occurred less frequently than previously reported for the general white male population.
