CONTEXT Decreased physical activity plays a critical role in the increase in childhood obesity. Although at least 60 minutes per day of moderate-to-vigorous physical activity (MVPA) is recommended, few longitudinal studies have determined the recent patterns of physical activity of youth. OBJECTIVE To determine the patterns and determinants of MVPA of(More)
Barth Syndrome is the only known Mendelian disorder of cardiolipin remodeling, with characteristic clinical features of cardiomyopathy, skeletal myopathy, and neutropenia. While the primary biochemical defects of reduced mature cardiolipin and increased monolysocardiolipin are well-described, much of the downstream biochemical dysregulation has not been(More)
OBJECTIVE Our prespecified dose-response analyses of A Very Early Rehabilitation Trial (AVERT) aim to provide practical guidance for clinicians on the timing, frequency, and amount of mobilization following acute stroke. METHODS Eligible patients were aged ≥18 years, had confirmed first (or recurrent) stroke, and were admitted to a stroke unit within 24(More)
BACKGROUND There is a rapid decline in moderate-to-vigorous physical activity (MVPA) during middle childhood and adolescence. Information on the environmental factors implicated in this decline is limited. This study focuses on family factors associated with the rate of decline in objectively measured physical activity during middle childhood and(More)
With childhood obesity tripling in the past two decades alone, developing effective treatment to promote long-term weight loss and maintenance is critical. Unfortunately, while many children respond favorably to behavioral treatments, failure to lose and maintain weight loss is common. There is a critical need to determine non-invasive markers that can(More)
BACKGROUND & OBJECTIVE Placental abruption, an ischemic placental disorder, complicates about 1 in 100 pregnancies, and is an important cause of maternal and perinatal morbidity and mortality worldwide. Metabolomics holds promise for improving the phenotyping, prediction and understanding of pathophysiologic mechanisms of complex clinical disorders(More)
Phthalates are plasticizers finding wide spread use in industrial and household products, with measureable levels of phthalate-derived metabolites in the general US population. Phthalates have endocrine disruption potential and have been implicated as obesogens. Our exploratory investigation to reveal the impact of in utero exposure to a phthalate on the(More)
