Study Design Historical cohort study. Background History of a knee joint injury and increased fat mass are risk factors for joint disease. Objective The objective of this study was to examine differences in adiposity, physical activity, and cardiorespiratory fitness between youths with a 3- to 10-year history of sport-related intra-articular knee injury and uninjured controls. Methods One hundred young adults (aged 15-26 years; 55% female) with a sport-related intra-articular knee injury sustained 3 to 10 years previously and 100 controls matched for age, sex, and sport, who had no history of intra-articular knee injury, were recruited. Fat mass index (FMI) and abdominal fat (fat mass at the L1 to L4 vertebral levels) were derived using dual-energy X-ray absorptiometry. Physical activity and cardiorespiratory fitness were measured using the Godin Leisure-Time Exercise Questionnaire and the multistage 20-meter shuttle run test for aerobic fitness, respectively. Results Previously injured participants demonstrated higher FMI (within-pair difference, 1.05 kg/m; 95% confidence interval [CI]: 0.53, 1.57) and abdominal fat (461 g; 95% CI: 228, 694) than uninjured controls. In multivariable linear regression analysis, previous injury was significantly associated with increased FMI. This increase was attenuated in those who participated in higher levels of physical activity or had higher estimated maximum volume of oxygen. Conclusion As a risk factor for osteoarthritis in an already susceptible group, excess adiposity is an undesirable trait in the potential pathway to joint disease. Increasing physical activity in this population may be a potential intervention to reduce adiposity thus impede disease initiation and/or progression. Level of Evidence Level 2b.

The popularity of youth basketball has increased over the past few decades at both competitive and recreational levels. 1-3 While high participation rates are essential for improved health and wellness in youth, injuries are a common occurrence in youth basketball. 4-6 Injuries in youth basketball players also have short and long term consequences that are
ObjectiveChildhood primary angiitis of the CNS (cPACNS) is a devastating neurologic disease. No standardized treatment protocols exist, and evidence is limited to open-label cohort studies and case reports. The aim of this review is to summarize the literature and provide informed treatment recommendations.MethodsA scoping review of cPACNS literature from January 2000 to December 2018 was conducted using Ovid, MEDLINE, PubMed, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, Vasculitis Foundation, European Vasculitis Society, CanVasc, Google Scholar, and Web of Science. Potentially relevant articles were selected for full-text review using the STROBE checklist if they met the following inclusion criteria: (1) reported treatment, (2) addressed pediatrics, (3) focused on the disease of interest, (4) included ≥5 patients, (5) original research, and (6) full-length articles. Reviews, expert opinions, editorials, case reports with <5 patients, articles lacking treatment information, or non-English articles were excluded. A standardized assessment tool measured study quality. Treatment and outcomes were summarized.ResultsOf 2,597 articles screened, 7 studies were deemed high quality. No trials were available so no meta-analysis was possible. Overall, treatment strategies recommended are induction with acute antithrombotic therapy subsequently followed by high-dose oral prednisone taper over 3–12 months and long-term platelet therapy. In angiography-positive progressive–cPACNS and angiography-negative–cPACNS, we also recommend 6 months of IV cyclophosphamide therapy, with trimethoprim/sulfamethoxazole as part of induction, and maintenance therapy with mycophenolate mofetil/mycophenolic acid.ConclusionNo grade-A evidence exists; however, this review provides recommendations for treatment of cPACNS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
