NCT ID: NCT04788199 Completed - Bariatric Surgery Clinical Trials

Novel Technique in Closure of Mesenteric Defects After Laparoscopic Roux-en-Y Gastric Bypass and Its Effect on Internal Hernia: a Case-control Study

Start date: June 15, 2018
Phase:
Study type: Observational

This study is to investigate the rate of internal hernia after laparoscopic Rox-en-Y gastric bypass when the defects are closed using cyano-acrylate glue.

NCT ID: NCT04779723 Completed - Bariatric Surgery Clinical Trials

30-Days Post-Operative Complications in Bariatric Surgery

Bariatric
Start date: June 13, 2018
Phase: N/A
Study type: Interventional

comparison of 30-days post-operative outcomes of laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB)

NCT ID: NCT04663919 Completed - Anorexia Nervosa Clinical Trials

Comparison of the Effects of Weight Changes on Serum Adipokines in Patients Diagnosed With Anorexia Nervosa and Morbid Obesity

Start date: January 1, 2014
Phase: N/A
Study type: Interventional

In this study, when patients diagnosed with AN started treatment and their weight increased by 10%; On the other hand, it was aimed to compare the changes in serum adipokine levels observed in morbidly obese patients before bariatric surgery and when they lost 10% of their post-op weight with both anthropometric measurements, biochemical parameters, and values of healthy volunteers.

NCT ID: NCT04609449 Completed - Bariatric Surgery Clinical Trials

A Comparison Between Short vs. Long Biliopancreatic Limb Gastric Bypass

Start date: January 2016
Phase: N/A
Study type: Interventional

Prospective study including patients submitted to RYGB (n=94) and L-RYGB (n=94) at a single institution. The aim was to compare the effect on comorbidities and weight loss of a long biliopancreatic limb Roux-en-Y gastric bypass (L-RYGB), compared with a standard RYGB. Procedure selection was randomly assigned (1:1), and surgeries were performed, during 24 months (2016-2017). Weight loss, comorbidities control and nutritional status were assessed at baseline and 12 months.

NCT ID: NCT04600596 Completed - Obesity, Morbid Clinical Trials

Photographic Food Recognition and Meal Size Estimation Before and After Roux-en-Y Gastric Bypass

Start date: June 1, 2019
Phase:
Study type: Observational

Direct measurements of changes in food selection in humans after RYGB have been limited by the unreliability of patients, which poses significant methodological and conceptual challenges to researchers and study design. Self-monitoring requires time and effort, and many find tracking of dietary intake tedious, which contributes to attrition. Direct measurements, however, represent an essential component in the attempt to understand how RYGB alters eating and food preferences, but laboratory settings preclude a real-life environment. The aim of this study is to investigate changes in food preferences, total energy intake of the three primary macronutrients and meal patterns between obese women (BMI ≥ 35) before and after Roux-en-Y gastric bypass and lean (BMI ≤ 25) and obese (BMI ≥ 35) controls by means of photographic food recognition with a mobile application.

NCT ID: NCT04517084 Completed - Bariatric Surgery Clinical Trials

Pre-surgical Motivation for Bariatric Surgery

Start date: August 13, 2018
Phase:
Study type: Observational

A study investigating the motivations of patients who had undergone bariatric surgery using data collected from questionnaires given to patients prior to surgery.

NCT ID: NCT04510389 Completed - Sarcopenia Clinical Trials

Impact of Whey Protein Supplementation on Body Weight and Metabolic Parameters of Bariatric Patients

Start date: March 1, 2019
Phase: N/A
Study type: Interventional

Obesity is a metabolic disorder, characterized by an increase in the body's fat mass, which will reflect an increase in total body weight. In Brazil, overweight accounts for 53.8% of the population, and of these 18.9% are obese. Surgical treatment is currently the most successful method for weight loss in patients with Grade III obesity and reduced associated morbidities. The general objective is to evaluate genetic, inflammatory, and dietary factors that would influence weight loss and the appearance of protein deficiency or sarcopenia in patients undergoing bariatric surgery and to evaluate the effects of protein supplementation for 8 weeks after the 18th postoperative month in the parameters evaluated. The study has a randomized, placebo-controlled, double-masked model. The patients will be selected in two bariatric surgery services accredited by the Brazilian Health Unic System (SUS) in the city of Belo Horizonte, Brazil. The project has already been approved by the Brazilian Ethics committee CONEP/UFMG by nº. 75415317.8.0000.5149. Patients of both sexes over 20 years of age will be included, attending the hospitals of the project with regular follow-up in the postoperative period. Data on anthropometry, body composition, muscle strength, energy expenditure, and inflammatory profile will be collected. The data will be correlated with the evaluation of the presence of genetic polymorphisms.

NCT ID: NCT04425005 Completed - Obesity Clinical Trials

Home-based Exercise Training During Covid-19 Pandemic in Post-bariatric

Start date: May 10, 2020
Phase: N/A
Study type: Interventional

The aim of this study is to assess the effect of a home-based exercise training during social isolation due to covid-19 pandemic in patients who undertook bariatric surgery.

NCT ID: NCT04413812 Completed - Physical Activity Clinical Trials

Fostering Exercise After Bariatric Surgery

FREEBASE
Start date: July 1, 2020
Phase: N/A
Study type: Interventional

While the benefits of engagement in regular physical activity after bariatric surgery has been established in various studies, little is known about the effectiveness of an interdisciplinary intervention including nutritional and psychological advice, hands-on training experience and motivational education to promote long-term adherence to a self-motivated active lifestyle in the bariatric surgery population. This randomized pilot intervention study called Fostering Exercise After Bariatric Surgery (FREEBASE) explores the efficacy of an interdisciplinary approach to promote physical activity-related health competence and an active lifestyle after bariatric surgery.

NCT ID: NCT04332289 Completed - Hypoglycemia Clinical Trials

Assessing Insulin Turnover Using an In-vivo Deuterated Water Experiment.

DEEP1A
Start date: July 9, 2020
Phase:
Study type: Observational

The primary objective of this study is to observe the kinetics of pre-stored and de-novo synthesized insulin that is secreted into the circulation using an in-vivo heavy water (D2O) labelling experiment in patients with postprandial hyperinsulinaemic hypoglycaemia (PHH) and non-surgical non-PHH controls.
