BACKGROUND The purpose of this study was to determine the validity of the SC-StepRx pedometer to assess moderate and vigorous physical activity during treadmill walking and running in a heterogeneous sample of children and youth aged 10-17 years. METHODS Physical activity intensity assessed via indirect calorimetry served as the criterion standard. A convenience sample of 40 participants (20 ...

Patients with chronic respiratory diseases have been found to develop malnutrition as a result of enhanced resting metabolic rate (RMR) associated with exacerbated ventilatory impairment. It is therefore necessary to measure each individual’s required amount of energy in order to provide nutritional support. There are few reports regarding the RMR of patients with chronic respiratory diseases t...

OBJECTIVES To review the nutritional evaluation in burned patient, considering the literature descriptions of nutritional evaluation and energy requirements of these patients. INTRODUCTION Thermal injury is the traumatic event with the highest metabolic response in critically ill patients. Various mathematical formulas have been developed to estimate nutritional requirements in burned patient...

PURPOSE Equations are frequently used to estimate resting energy expenditure (REE) in a clinical setting. However, few studies have examined their accuracy in end-stage renal disease (ESRD) patients. PATIENTS AND METHODS To investigate agreement between indirect calorimetry and several REE estimating equations in 38 ESRD patients on peritoneal dialysis, we performed indirect calorimetry and c...
