PURPOSE The purpose of this study is to compare the resting energy expenditure (REE) obtained by indirect calorimetry (IC) to the REE calculated by predictive equations (Brandi and Liggett) using the oxygen consumption (VO2) obtained by Fick's method in septic patients. METHODS Prospective study in septic patients admitted in an intensive care unit of a university hospital. Fifteen adult pati...

Early pregnancy is characterized by the institution of a high-flow low-resistance circulation. In this study, we tested the hypothesis that these hemodynamic changes develop independently of changes in basal metabolic rate. In 12 healthy women, we determined and calculated once during the follicular phase (day 5 +/- 2) and at 6, 8, 10, and 12 wk of pregnancy the following variables: body weight...

Nutritional status is both important and difficult to assess in patients with Duchenne muscular dystrophy (DMD), particularly in those requiring mechanical ventilation (MV). The current authors evaluated body composition (bio-impedancemetry), resting energy expenditure (REE; indirect calorimetry) and energy intake in 20 adult patients with DMD using home MV (nocturnal: n = 13; continuous: n = 7...

This paper is the written explanation for a demonstration of the REE Project’s work to-date. The demonstration is intended to simulate an REE system that might exist on a Mars Rover, consisting of multiple COTS processors, a COTS network, a COTS node-level operating system, REE middleware, and an REE application. The specific application pecforms texture processing of images. It was chosen as a...

OBJECTIVE To investigate energy balance in children with sickle cell disease (SCD) as the possible cause of impaired growth and undernutrition. STUDY DESIGN Growth, resting (REE), total (TEE), and activity-related (AEE) energy expenditure and dietary intake were examined in 36 African American children with SCD (20 girls and 16 boys) and 30 control subjects (15 girls and 15 boys) of similar a...

An open circuit indirect calorimeter was used to measure resting energy expenditure in febrile infants. Twelve infants admitted to hospital with fever (axillary temperature 37.5 degrees C) were studied on admission and then again at the same time of day and in similar environmental conditions after the fever had resolved. Mean age of the infants was 0.31 years (range 0.12-0.54) and the mean bod...

Short-chain fatty acids (SCFAs), produced from fermentation of dietary fibre by the gut microbiota, have been suggested to modulate energy metabolism. Previous work using rodent models has demonstrated that oral supplementation of the SCFA propionate raises resting energy expenditure (REE) by promoting lipid oxidation. The objective of the present study was to investigate the effects of oral so...

There is a sparsity of data on energy expenditure in young children. We therefore examined the components of daily energy expenditure in a group of 30 children (16 boys, 14 girls; age 4-6 yr) characterized for body weight, height, heart rate, and body composition from bioelectrical resistance. Total energy expenditure (TEE) was measured over 14 days under free living conditions by doubly labele...

A detailed hydrogeochemical study was performed in the Wiśniówka mining area (south-central Poland). This covered three acid pit bodies, historic tailings acid ponds, acid pools, and additionally two neighboring rivers. All these acid mine drainage (AMD) waters are characterized by the pH in the range of 1.7 (pools) to 3.5 (tailings ponds). The most interesting is the Podwiśniówka acid pit lake...
