Obesity is an important risk factor for hypertension; however, the pathway through which it raises blood pressure (BP) is poorly understood. Body size is also the primary determinant of energy expenditure, and we therefore examined the joint relationship of energy expenditure and body size to blood pressure. Resting energy expenditure (REE) was measured using respiratory gas exchange in populat...

An enduring enigma is why the ratio of resting energy expenditure (REE) to metabolically active tissue mass, expressed as the REE/fat-free mass (FFM) ratio, is greater in magnitude in subjects with a small FFM than it is in subjects with a large FFM. This study tested the hypothesis that a higher REE/FFM ratio in subjects with a small body mass and FFM can be explained by a larger proportion of...

BACKGROUND Recommendations for energy intake in obese children rely on accurate methods for measuring energy expenditure that cannot be assessed systematically. OBJECTIVE The aim was to establish and validate new equations for predicting resting energy expenditure (REE), specifically in obese children. DESIGN REE (indirect calorimetry) and body composition (bioelectrical impedance analysis)...

BACKGROUND The prevalence of overweight and obesity in Mexico is approximately 70%; thus, obtaining a reliable measurement of the resting energy expenditure (REE) in these patients is of extreme importance. The aim of the study was to obtain a prediction equation of REE in overweight or obese outpatients in the Mexican population. METHODS The study was conducted at The National Institute for ...

Mechanisms of uptake of rare earth elements (REEs) were investigated, particularly those by REE accumulator species (autumn fern). Rare earth elements are practically insoluble under natural conditions, suggesting some unknown mechanism in REE accumulator species. In the present investigation, two notable phenomena were observed. (I) Concerning the ionic-radius dependence of REE uptake by leave...

Recent findings Several prospective series have reported consistent rates of PPI-REE (30–40%) in adults with suspected EoE. At baseline, PPI-REE and EoE have been shown to be indistinguishable upon clinical, endoscopic, and molecular characteristics [eotaxin-3, interleukin (IL-5), and IL-13 expression]. PPI therapy partially restores esophageal mucosal integrity in PPI-REE, but not in EoE. Anti...

BACKGROUND Accurate measurement of resting energy expenditure (REE) is helpful in determining the energy needs of critically ill patients requiring nutritional support. Currently, the most accurate clinical tool used to measure REE is indirect calorimetry, which is expensive, requires trained personnel, and has significant error at higher inspired oxygen concentrations. OBJECTIVE The purpose ...

34 35 Background: A decline in resting energy expenditure (REE) beyond that predicted from 36 changes in body composition has been noted following dietary-induced weight loss. 37 However, it is unknown whether a compensatory down-regulation in REE also accompanies 38 exercise-induced weight loss, or whether this adaptive metabolic response influences energy 39 intake (EI). Methods: Thirty overw...

BACKGROUND AND AIMS Nutritional status is a prognostic factor for survival in amyotrophic lateral sclerosis (ALS) patients. We investigated the contribution of some of the components contributing to resting energy expenditure (REE) in order to determine whether potentially higher energy needs should be considered for these patients. METHODS Thirty three ALS patients and 33 age- and gender-mat...
