The assessment of extra-, intracellular and total body water (ECW, ICW, TBW) is important in many clinical situations. Bioimpedance spectroscopy (BIS) has advantages over dilution methods in terms of usability and reproducibility, but a careful analysis reveals systematic deviations in extremes of body composition and morbid states.

BACKGROUND Excess fluid (ExF) accumulates in the body in many conditions. Currently, there is no consensus regarding methods that adequately distinguish ExF from fat-free mass. OBJECTIVE The aim was to develop a model to determine fixed hydration constants of primary body tissues enabling ExF to be calculated from whole-body measurements of weight,(More)
Objective:To compare the value of body fat mass (%FM) to indirect measures of general (body mass index (BMI)) and central adiposity (waist circumference (WC); waist-to-height ratio (WC/ht)) for the prediction of overweight- and obesity-related metabolic risk in a study population with a high prevalence of metabolic syndrome (MSX).Methods:BMI, WC, WC/ht,(More)
Objective:There are considerable differences in published prediction algorithms for resting energy expenditure (REE) based on fat-free mass (FFM). The aim of the study was to investigate the influence of the methodology of body composition analysis on the prediction of REE from FFM.Design:In a cross-sectional design measurements of REE and body composition(More)
Current anthropometric indices for health risk assessment are indirect measures of total or visceral body fat mass that do not consider the inverse relationship of lean body mass to metabolic risk as well as the non-linear relationship between central obesity and insulin resistance. We examined a new anthropometric index that reflects the relationship of(More)
Objective:The phenotypic heterogeneity of metabolic syndrome (MSX) suggests heterogeneity of the underlying genotype. The aim of the present study was to examine the common genetic background that contributes to the clustering between the two main features (insulin resistance, central obesity) and different MSX component traits.Methods:In all, 492(More)
Although the coronoid process is not part of the temporomandibular joint, hyperplasia of the coronoid process can effect the mandibular movement as the result of the impingement on the zygomatic arch which is demonstrated in the case of a 22-year-old man. In order to access the prevalence of the asymptomatic enlargement of the coronoid process we carried(More)
Air-displacement plethysmography (ADP) is now widely used for body composition measurement in pediatric populations. However, the manufacturer's software developed for adults leaves a potential bias for application in children and adolescents, and recent publications do not consistently use child-specific corrections. Therefore we analyzed child-specific(More)
Antithrombin III and protein C are the major inhibitors of the plasma clotting system. Since adequate thromboembolism protection requires a cofactor AT III for heparin to provide full antithrombotic coverage, the preoperative AT III and protein C levels in the plasma of 105 patients treated with marcumar are measured. The understanding of the physiological(More)
