AIMS: Depressive symptoms are commonly reported by haemodialysis (HD) patients. Previous reports have suggested an association between depression and nutritional status. To investigate this, we measured muscle mass in HD patients screened for depression. METHODS: The Beck Depression Inventory-II (BDI-II), Hospital Anxiety and Depression Scale (HADS) were used to screen for depression, and quality of life assessed by the short form 36 (SF36), and measured appendicular lean mass (ALM) post-dialysis with segmental bioimpedance...

OBJECTIVE: Although adipose tissue hydrogen peroxide (H2O2) and its metabolizing enzymes have been linked to obesity and insulin resistance in animal studies, this relation remains to be evaluated in humans. METHODS: Non-diabetic men (N = 43, median age, 49 (37, 54 y)) undergoing abdominal surgeries were studied. Participants were classified by body mass index (BMI) into normal-weight (N = 19), or overweight/obese (Ow/Ob; BMI ≥25; N = 24). Centrally obese men were identified by waist-height ratio ≥0...

SCOPE: In recent years, several studies reported the role of eIF4E-binding proteins (4E-BPs) on the development of diet-induced obesity and insulin resistance. Our aim was to investigate the effect of 4E-BP protein deletion on lipid accumulation and metabolism in skeletal muscle in response to a high fat diet-induced obesity in 4E-BP1/2 DKO mice. METHODS AND RESULTS: Diet-induced obesity engendered increased ectopic accumulation of lipotoxic species in skeletal muscle of 4E-BP1 and 4E-BP2 double-knockout mice (4E-BP1/2 DKO), namely diacylglycerols and ceramides...

The onset and progression of diabetes mellitus type 2 is highly contingent on the amount of functional beta-cell mass. An underlying cause of beta-cell decay in diabetes is oxidative stress, which markedly affects the insulin producing pancreatic cells due to their poor antioxidant defence capacity. Consequently, disturbances of cellular redox signaling have been implicated to play a major role in beta-cell loss in diabetes mellitus type 2. There is evidence suggesting that the glutaredoxin (Grx) system exerts a protective role for pancreatic islets, but the exact mechanisms have not yet been elucidated...

BACKGROUND: Intensive physical exercise (IPE) increases strength, lean body mass, aerobic capacity, and range of motion in children with extensive burns. However, whether IPE decreases the frequency of burn scar contracture-releasing procedures in children with extensive burns is unknown. MATERIALS AND METHODS: Prospectively collected surgical records of 184 children who had undergone axilla, elbow, and/or wrist contracture-releasing procedures were reviewed. All children were 7 years or older and had sustained burns of at least 40% of the total body surface area...

INTRODUCTION: Maximizing fat mass (FM) loss while preserving or increasing fat-free mass (FFM) is a central goal for athletic performance but the composition of body weight (BW) changes over time with training are largely unknown. PURPOSE: We aimed to analyze FM and FFM contributions to BW changes and to test if these contributions follow established rules and predictions over one athletic season. METHODS: 70 athletes (42 males; handball, volleyball, basketball, triathlon, and swimming) were evaluated from the beginning to the competitive stage of the season and were empirically divided into those who lost (n=20) or gained >1...

Obese women, on average, give birth to babies with high fat mass. Placental lipid metabolism alters fetal lipid delivery, potentially moderating neonatal adiposity, yet how it is affected by maternal obesity is poorly understood. We hypothesized that fatty acid (FA) accumulation (esterification) is higher, and FA oxidation (FAO) is lower, in placentas from obese, compared to lean women. We assessed acylcarnitine profiles (lipid oxidation intermediates) in mother-baby-placenta triads, in addition to lipid content, and mRNA/protein expression of key regulators of FA metabolism pathways, in placentas of lean and obese women with normal glucose tolerance recruited at scheduled term Cesarean delivery...

HIV-associated lipodystrophy syndrome (HALS) is characterized by body fat redistribution as a consequence of the antiretroviral therapy (ART) introduction, associated with an increased risk of cardiovascular disease development. Subjective diagnosis, classified between three subtypes according to the body region on which fat is lost and/or accumulated, named lipoatrophy, lipohypertrophy, and mixed lipodystrophy, is possibly accompanied with metabolic alterations. Forty people living with HIV/AIDS (PLHA), with clinical diagnosis of HALS and from both genders, were assessed...

PURPOSE: Studies demonstrated the influence of mother's obesity on offspring. However, the father is also related to programming the future generation. The study aimed to evaluate the effects of father's obesity upon white adipose tissue (WAT) remodeling, resulting in activation of signaling pathways and inflammation in male and female offspring. METHODS: Male C57BL/6 mice received control diet (lean father group; 17% energy from lipids) or high-fat diet (obese father group; 49% energy from lipids) for 8 weeks before mating...

BACKGROUND: Estimating volumes and masses of total body components is important for the study and treatment monitoring of nutrition and nutrition-related disorders, cancer, joint replacement, energy-expenditure and exercise physiology. While several equations have been offered for estimating total body components from MRI slices, no reliable and tested method exists for CT scans. For the first time, body composition data was derived from 41 high-resolution whole-body CT scans. From these data, we defined equations for estimating volumes and masses of total body AT and LT from corresponding tissue areas measured in selected CT scan slices...

Both the history of obesity and weight loss may change how menopause affects metabolic health. The purpose was to determine whether obesity and/or weight loss status alters energy balance (EB) and subsequent weight gain after the loss of ovarian function. Female lean and obese Wistar rats were randomized to 15% weight loss (WL) or ad libitum fed controls (CON). After the weight loss period, WL rats were kept in EB at the reduced weight for 8 weeks prior to ovariectomy (OVX). After OVX, all rats were allowed to eat ad libitum until weight plateaued...

PURPOSE: Tartrate resistant acid phosphatase (TRAP) exists as two isoforms, 5a and 5b. TRAP 5a is elevated in adipose tissue of obese women, interacts with pre-adipocytes and is linked to insulin-sensitive hyperplastic obesity when overexpressed in mice. The aim of this study was to investigate the relation between serum TRAP 5a, adiposity indices and metabolic syndrome risk markers in lean and obese women, using a newly developed TRAP 5a-specific ELISA. MATERIALS AND METHODS: A TRAP 5a sandwich ELISA was optimized using TRAP 5a-specific monoclonal antibodies and tested in sera of healthy males...

BACKGROUND & AIMS: Resting energy expenditure (REE) changes in patients with chronic kidney disease (CKD) may contribute to mortality increase. The obesity and inflammation is associated with high REE and when not compensated by adequate intake, may determine an unfavorable clinical outcome in this population. We aimed to evaluate the influence of metabolic syndrome (MetS) on REE in CKD patients. METHODS: One hundred eighty-three patients were stratified according to glomerular filtration rate (GFR) and divided in groups: without CKD (GFR > 60 ml/min/1...
