BACKGROUND The risks of sports participation for implantable cardioverter-defibrillator (ICD) patients are unknown. METHODS AND RESULTS Athletes with ICDs (age, 10-60 years) participating in organized (n=328) or high-risk (n=44) sports were recruited. Sports-related and clinical data were obtained by phone interview and medical records. Follow-up occurred(More)
OBJECTIVE The childhood obesity epidemic has been accompanied by an increasing prevalence of type 2 diabetes (T2D), particularly in minority children. Twenty to thirty percent of obese youth have "prediabetes," a precursor to diabetes marked by insulin resistance, β-cell dysfunction, and impaired glucose tolerance. The Diabetes Prevention Program(More)
Obesity is a significant risk factor for developing diabetes. Pigment epithelium-derived factor (PEDF) has been identified by experimental and clinical studies as both a causative and counter-regulatory factor in the metabolic syndrome. We set out to determine whether serum PEDF levels correlated with the degree of insulin resistance in morbidly obese(More)
BACKGROUND Routine resection of cavity shave margins (additional tissue circumferentially around the cavity left by partial mastectomy) may reduce the rates of positive margins (margins positive for tumor) and reexcision among patients undergoing partial mastectomy for breast cancer. METHODS In this randomized, controlled trial, we assigned, in a 1:1(More)
OBJECTIVE There are limited data on outcomes and predictors of health-related quality of life (HRQOL) of ovarian cancer survivors. Therefore, we examined the trajectory and predictors of HRQOL one- and two-years post-diagnosis in this population. METHODS 365 ovarian cancer survivors, a subset of participants in the longitudinal American Cancer Society's(More)
PURPOSE Arthralgia occurs in up to 50% of breast cancer survivors treated with aromatase inhibitors (AIs) and is the most common reason for poor AI adherence. We conducted, in 121 breast cancer survivors receiving an AI and reporting arthralgia, a yearlong randomized trial of the impact of exercise versus usual care on arthralgia severity. PATIENTS AND(More)
OBJECTIVE Fructose consumption has risen alongside obesity and diabetes. Gut hormones involved in hunger and satiety (ghrelin and PYY) may respond differently to fructose compared with glucose ingestion. This study evaluated the effects of glucose and fructose ingestion on ghrelin and PYY in lean and obese adolescents with differing insulin sensitivity. (More)
BACKGROUND The optimal treatment of malaria in human immunodeficiency virus (HIV)-infected children requires consideration of critical drug-drug interactions in coinfected children, as these may significantly impact drug exposure and clinical outcomes. METHODS We conducted an intensive and sparse pharmacokinetic/pharmacodynamic study in Uganda of the most(More)
PURPOSE Non-small cell lung cancer (NSCLC) includes a spectrum of radiosensitive and radioresistant tumors. However, little is known about the molecular determinants of cellular radiation responses. We examined clinical outcomes after gamma knife radiotherapy for NSCLC intracranial metastases to evaluate the use of this model for determining radiosensitive(More)
