INTRODUCTION One of the goals of modern ventral hernia repair (VHR) is restoring the linea alba by returning the rectus muscles to the midline. Although this practice presumably restores native abdominal wall function, improvement of abdominal wall function has never been measured in a scientific fashion. We hypothesized that a dynamometer could be used to(More)
OBJECTIVE While various weight-management approaches produce weight loss, they may differ in dietary quality. We monitored changes in nutrient intakes in overweight and obese subjects on three different weight-management programs. DESIGN Randomized clinical trial (pilot study) with two 12-week phases: phase 1, weekly counseling; phase 2, monitoring only.(More)
BACKGROUND To date, there has been no standardized approach to the assessment of aerobic fitness among children who harbor parasites. In quantifying the disability associated with individual or multiple chronic infections, accurate measures of physical fitness are important metrics. This is because exercise intolerance, as seen with anemia and many other(More)
After single-ventricle palliation, patients have variable long-term functional outcomes. Cardiopulmonary exercise testing (CPET) is an assessment tool used to quantify functional outcome. Oxygen pulse kinetics during CPET, which can be an important indicator of dynamic changes in stroke volume reserve, has not been systematically studied in this population.(More)
BACKGROUND Indirect calorimetry requires a steady state (SS) protocol to determine measured resting energy expenditure (mREE). Achieving stringent criteria for an SS interval may be difficult for patients on maintenance hemodialysis (MHD), as they may become uncomfortable because of the test itself or their health status. The study aim was to explore if a(More)
BACKGROUND Hypermetabolism is theorized in patients diagnosed with chronic kidney disease who are receiving maintenance hemodialysis (MHD). We aimed to distinguish key disease-specific determinants of resting energy expenditure to create a predictive energy equation that more precisely establishes energy needs with the intent of preventing protein-energy(More)
OBJECTIVE To investigate the effect of Vitamin D3 on physical performance in patients with HF. BACKGROUND HF is associated with functional decline and frailty. Vitamin D deficiency is associated with loss of muscle strength and poor outcomes in patients with HF. METHODS Sixty-four patients participated in a 6-month parallel design double blind RCT to(More)
BACKGROUND Vitamin D is a fat-soluble hormone necessary for calcium homeostasis. Recently, studies have demonstrated that vitamin D may be important to the health of the cardiovascular system. METHODS Adults ≥ 50 years of age with heart failure were recruited for assessment of serum 25-hydroxyvitamin D (25OHD) concentrations. Cardiopulmonary exercise(More)
