Obesity is a serious metabolic disease that significantly increases cardiovascular risks and other health complications. Sarcopenia is an independent risk factor for morbidity and mortality in patients suffering from obesity that increases the health risks and is associated with cardiac, respiratory and other diseases. Bariatric and metabolic surgery (BMS) leads to significant changes in body composition. Our pilot study showed that bariatric patients are at risk of sarcopenia after BMS. This finding resulted in a hypothesis that an exercise plan in the experimental group will lead to postural stabilization and a lower decline in muscle homotopy, further leading to a greater reduction in fat mass and a positive effect of exercise on skeletal muscle volume and strength and endocrine-metabolic function. The aim of the present study is to determine the effect of programmed aerobic and strength training on muscle function, volume, and morphology in patients after BMS. The study is a single-center, randomized clinical trial after sleeve gastrectomy focused on muscle tissue. The experimental group will perform targeted physical activity once a week for 12 months and the training plan will include anaerobic and aerobic components. Magnetic resonance imaging of skeletal muscles will be correlated with the values of densitometry examination and changes in body composition, certain blood parameters of myokines, biomechanical analysis of movement abnormalities, and behavioral and dietary counseling. This study will address the research questions about the effect of programmed training on muscle tissue and muscular functions after BMS.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD), often associated with obesity and metabolic syndrome, manifests itself as steatosis, hepatic fibrosis, cirrhosis, or even end-stage liver disease. NAFLD causes inflammation, insulin resistance and cardiovascular complications. The current study aimed to evaluate the beneficial effects of bariatric surgery on biochemical parameters of hepatic functions in obese patients by comparing them before and one-year after the surgery. METHODS: A total of 72 morbidly obese patients underwent bariatric surgery between 2016 and 2018. The incidence of diabetes mellitus in this group was 29%, median body weight was 124.5 kg (109.0-140.0) and mean body mass index (BMI) was 44.38 ± 6.770 kg/m2. The used surgical procedures included gastric bypass, sleeve gastrectomy, laparoscopic gastric plication, and single anastomosis duodeno-ileal bypass-sleeve gastrectomy. Biochemical parameters including ALT/AST ratio (AAR), NAFLD fibrosis score (NFS), hepatic fibrosis index (FIB-4) and Fatty Liver Index (FLI) were evaluated in all patients at the time of surgery and one year after the intervention. RESULTS: Significant improvement after the intervention was observed in 64 patients. A significant reduction in body weight (P<0.0001), waist circumference (P<0.0001), and body mass index (P<0.0001) were observed. NAFLD liver fibrosis index changed significantly (P<0.0001), suggesting a trend of improvement from advanced fibrosis towards stages 0-2. The FIB-4 fibrosis index indicated significant improvement (P=0.0136). Besides, a significant decline in hepatic steatosis (P<0.0001) was observed after bariatric surgery as compared to the pre-surgery fatty liver conditions. CONCLUSION: Among the strategies to overcome NAFLD-associated impediments, bariatric surgery can be considered effective in reducing obesity and metabolic co-morbidities.

BACKGROUND: Surgery for obesity and metabolic diseases has been evolved in the light of new scientific evidence, long-term outcomes and accumulated experience. EAES has sponsored an update of previous guidelines on bariatric surgery. METHODS: A multidisciplinary group of bariatric surgeons, obesity physicians, nutritional experts, psychologists, anesthetists and a patient representative comprised the guideline development panel. Development and reporting conformed to GRADE guidelines and AGREE II standards. RESULTS: Systematic review of databases, record selection, data extraction and synthesis, evidence appraisal and evidence-to-decision frameworks were developed for 42 key questions in the domains Indication; Preoperative work-up; Perioperative management; Non-bypass, bypass and one-anastomosis procedures; Revisional surgery; Postoperative care; and Investigational procedures. A total of 36 recommendations and position statements were formed through a modified Delphi procedure. CONCLUSION: This document summarizes the latest evidence on bariatric surgery through state-of-the art guideline development, aiming to facilitate evidence-based clinical decisions.

The constantly growing incidence of obesity represents a risk of health complications for individuals, and is a growing economic burden for health care systems and society. The aim of this study was to evaluate the efficacy of bariatric surgery, specifically laparoscopic greater curve plication, laparoscopic sleeve gastrectomy, and Roux-en-Y gastric bypass, in patients with type 2 diabetes mellitus. The effect of bariatric surgery on the changes in blood pressure before, and 12 months after, surgery and in pharmacotherapy in the 12 months after surgery was analyzed. For achieving this purpose, 74 patients from the Obesity and Surgery Department of Vitkovice Hospital in Ostrava in the Czech Republic, were monitored. They were operated in 2011 and 2012. The Bonferroni method was used to test hypotheses about the impact of surgery on blood pressure and pharmacotherapy. One year after the surgery, systolic and diastolic blood pressure values decreased, both with no statistically significant difference between surgery types. Improvement was observed in 68% of cases, with 25% of patients discontinuing pharmacotherapy entirely.

INTRODUCTION: Laparoscopic greater curvature plication (LGCP) is a novel restrictive technique that reduces gastric volume by plication of the greater curvature. The advantage of LGCP is its reversibility in comparison to laparoscopic sleeve gastrectomy. Nowadays, the long-term LGCP efficacy, safety and metabolic effect are being investigated. AIM: To assess body composition, clinical complications and metabolic changes in obese patients 6 and 12 months after laparoscopic greater curvature plication. MATERIAL AND METHODS: A total of 70 subjects underwent LGCP; 52 of them (33 women and 19 men) completed 1-year follow-up study. Anthropometry and biochemical parameters (glucose, glycated haemoglobin, lipids, ghrelin, leptin, adiponectin and fibroblast growth factor 21 [FGF-21]) were assessed before and 3, 6, and 12 months after surgery. RESULTS: All study participants exhibited statistically significant weight loss at both 6 and 12 months following the LGCP compared to baseline, with significant reductions in body composition - body weight, body mass index, percentage excess weight loss (%EWL), and percentage excess BMI loss (%EBL) (p ≤ 0.001). Moreover, significant lowering of glucose and glycated haemoglobin, triacylglycerols and leptin was observed 12 months after LGCP. On the other hand, plasma concentrations of ghrelin, adiponectin and LDL cholesterol increased significantly. Total cholesterol, LDL cholesterol and FGF-21 levels did not change significantly. CONCLUSIONS: Laparoscopic greater curvature plication appears to be a procedure with good restriction results, which might be mediated through alteration in incretin metabolism. Technical aspects and standardization of the procedure still remain to be worked out.
