The aim of the present study was to assess the sensitivity of bio-impedance (BIA) in tracking body composition changes in adolescents with various degrees of obesity. We hypothesized that while BIA provides a reliable measure of body composition, its accuracy decreases with increasing obesity and its ability to track changes might be reduced with higher degree of body weight and body composition. Whole-body and segmental body composition were assessed by bio-impedance analysis (BIA-Tanita MC-780) and dual x-ray absorptiometry (DXA, Hologic) among 196 obese adolescents (Tanner stage 3-5) aged 14 ± 0...

BACKGROUND: Maternal prenatal smoking is associated with downstream childhood obesity. Although animal research suggests reduced resting energy expenditure (REE), decreased physical activity (PA), and increased energy intake as mechanisms, these relationships are unclear in humans. The objectives were to examine the association of prenatal maternal smoking with non-volitional energy expenditure (REE and the thermic effect of feeding [TEF]), child adiposity, energy intake, free-living PA (daily light PA (LPA), daily moderate-to-vigorous PA (MVPA), daily sedentary behavior (SB)), and screen time (television and computer/video game) in children...

Bioelectrical impedance spectroscopy (BIS) instantly assesses body composition to monitor the effects of diet, competition, and illness, though it requires a body proportion factor (Kb). This study aimed to validate a draft horse-specific Kb. The calculated Kb was 1.42, resulting in significantly lower body composition values, with the exception of fat mass.

BACKGROUND: Although central venous pressure (CVP) is a surrogate measure of preload in patients with acute decompensated heart failure (ADHF), it is a multifactorial index influenced not only by fluid volume status, but also by cardiac pump function and other factors. We aimed to elucidate the individual pathophysiologic factors of CVP elevation in ADHF patients by assessing the relationship between CVP and extracellular fluid volume status (EVS). METHODS AND RESULTS: We quantified EVS in 100 ADHF patients using bioelectrical impedance analysis...

BACKGROUND: Acute kidney injury (AKI) complicates shock. Diagnosis is based on rising creatinine, a late phenomenon. Intrarenal vasoconstriction occurs earlier. Measuring flow resistance in the renal circulation, Renal Resistive Index (RRI), could become part of vital organ function assessment using Doppler ultrasound. Our aim was to determine whether RRI on ICU admission is an early predictor and discriminator of AKI developed within the first week. METHODS: In this prospective cohort of mixed ICU patients with and without shock, RRI was measured <24-h of admission...

PURPOSE OF THE STUDY: Sarcopenia has been identified as a health hazard in elderly people. Although the association between sarcopenia and a decrease in masticatory function has been reported, the mechanism underlying this association has not been widely reported. Therefore, in order to elucidate the relationship between sarcopenia and masticatory function, we examined whether the masseter muscle thickness (MMT), which is a factor influencing masticatory function, in community-dwelling elders is associated with the appendicular skeletal muscle index (SMI), a diagnostic criterion for sarcopenia...
