Standard Equations Are Not Accurate in Assessing Resting Energy Expenditure in Patients With Amyotrophic Lateral Sclerosis
|
ABSTRACT. Objective: To assess the utility of standard equations for calculating caloric requirements in patients with amyotrophic lateral sclerosis (ALS). Background: Malnutrition substantially increases the risk of death in ALS. Weight loss can be stabilized and survival prolonged with early gastrostomy feeding. However the use of standard nutrition equations has not been validated in this population. We therefore compared measured caloric expenditure to 2 predictive equations in patients w...

Measurement of 24 h energy expenditure in male tuberculosis patients
Indian Journal of Medical Research
; Background & objectives: The total daily energy expenditure in patients with infectious disease is presumed to be high because of an increase in the basal metabolic rate (BMR), a reason for the weight loss observed in these patients. A reduction in daily physical activity, which may reduce the

Energy Expenditure in Hospitalized Patients: Implications for Nutritional Support
Mayo Clinic Proceedings
; An understanding of energy expenditure in hospitalized patients is necessary to determine optimal energy supply in the care of individuals who require nutritional support. A review was conducted of 19 studies in which resting energy expenditure (REE) had been measured using indirect calorimetry and

Substrate oxidation in patients with cirrhosis: comparison with other nutritional markers
JPEN, Journal of Parenteral and Enteral Nutrition
; ABSTRACT. Background: Malnutrition in patients with hepatic cirrhosis is associated with abnormal fuel metabolism marked by reduced glucose oxidation and increased lipid oxidation. A low respiratory quotient (R/Q) indicates reduced glucose and increased lipid oxidation. The aim of this study was to
