Aim Although the association of vitamin D with primary sarcopenia has been extensively investigated, its relationship with secondary sarcopenia in patients with liver disease remains unclear. This study aimed to identify factors associated with sarcopenia in patients with chronic liver disease with a focus on serum vitamin D levels. Methods The study included 204 patients with chronic liver disease. Independent factors significantly associated with sarcopenia were determined using multiple logistic regression analysis. The …

Background Although bariatric surgery can achieve sustained weight loss, there are major differences in the magnitude of weight change post-operatively. Reduced resting energy expenditure (REE) plays an important role in unsatisfactory weight loss effect by contributing to positive energy balance. Objectives To identify pre-and post-surgical predictors related to satisfactory percent of total weight loss (% TWL) in Chinese individuals with obesity after laparoscopic sleeve gastrectomy (LSG). Methods A retrospective cohort study was …

Obesity represents a major public health problem and is the fifth leading risk factor for mortality. Morbid obesity is associated with chronic systemic inflammation which increases the risk of comorbidities. Bariatric surgery (BS) is considered an effective intervention for obese patients. However, BS is associated with dietary restriction, potentially limiting physical activity. Whole-body neuromuscular electrical stimulation (WBS) could represent an innovative option for the rehabilitation of BS patients, especially during the early …

Background: The association between anthropometric and metabolic indices and fatty liver (FL) remain not fully elucidated. We aimed to determine the role of these anthropometric and metabolic indices on FL prediction and regulation via cross-sectional study, thus providing clues for further research in FL field. Methods: A total of 658 participants aged over 18 years were included in this study. Anthropometric and metabolic indices (including WC, WHR, BMI, BFM, VFA, TG/HDL, AST/ALT, SBP, DBP and FBG) were measured. Difference analyses …

Background Weight loss may decrease the energy expenditure (EE) because of changes in body composition (BC). The reduction in EE may contribute, in part, to weight regain. Experimental studies in animals indicate that Roux-en-Y Gastric Bypass (RYGB) increases the resting metabolic rate (RMR) when adjusted for body weight (BW). Thus, the aim of this study was to assess the clinical effects of RYGB on EE in patients who have undergone RYGB. Methods The study was prospective and included 46 RYGB patients whose RMR …

Objective To assess the rapid improvement of insulin sensitivity and β‐cell function following biliopancreatic diversion with duodenal switch (BPD‐DS) and determine the role played by caloric restriction in these changes. Methods Standard meals were administrated before and on day 3, 4, and 5 after BPD‐DS to measure total caloric intake, glucose excursion, insulin sensitivity, and secretion in matched type 2 diabetes and normoglycemic (NG) subjects. In a second set of study, other subjects with type 2 diabetes had the same meal tests prior to and …

Background & aims Bariatric surgery is increasingly common in the fight against morbid obesity. However, after this intervention, it is not fully understood the evolution of weight loss and how body composition changes. The objective of this work is to study the evolution after surgery of weight and body composition of obese patients that underwent bariatric surgery. Methods In this retrospective and prospective study, we studied initially BMI and body composition of obese patients who attended nutritional appointments at Centro Hospitalar …

Laparoscopic Roux-en-Y gastric bypass (LRYGBP) reduces appetite and induces significant and sustainable weight loss. Circulating gut hormones changes engendered by LRYGBP are implicated in mediating these beneficial effects. Laparoscopic sleeve gastrectomy (LSG) is advocated as an alternative to LRYGBP, with comparable short-term weight loss and metabolic outcomes. LRYGBP and LSG are anatomically distinct procedures causing differential entero-endocrine cell nutrient exposure and thus potentially different gut …

Methods Samples (n= 63) were allocated to three groups: Obese without HTN and T2DM (n= 29), Obese with HTN (OHTN, n= 17) and OHTN with T2DM (OHTN+ T2DM, n= 17), in which anthropometric measures, body composition, blood biochemical parameters, blood pressure (BP) and heart rate variability (HRV) were evaluated. Results The age was higher in OHTN+ T2DM and OHTN than in obese groups (p< 0.05). OHTN+ T2DM individuals had increased neck circumference and compromised glycemic profile when compared to obese …

Purpose This study aimed at assessing nutrient adequacy after 1 year in patients who had undergone gastric bypass (GB) surgery or sleeve gastrectomy (SG) and to investigate the association of nutrient adequacy with anthropometric indices. Methods A total of 180 severely obese patients (BMI≥ 35 kg/m 2) were selected among the participants of Tehran Obesity Treatment Study. Nutritional assessments were performed over 3 days of 24-h dietary recall. To evaluate the nutrient adequacy ratio (NAR), the subject's nutrient intake …
