Filter by:The goal of this pilot study is to evaluate the magnitude of changes in glucose and hormone levels in response to structured exercise in the fasting state in individuals with post-bariatric hypoglycemia (PBH). This pilot study will assess the adequacy of a protocol to test the following hypotheses: (1) hypoglycemia will develop in individuals with PBH in response to exercise; (2) counterregulatory hormonal responses to hypoglycemia during exercise are impaired in individuals with PBH.
The overall aim of this study is to develop a sustainable hypoglycemia correction strategy.
The overall aim of this study is to prevent hypoglycemic events in patients with hypoglycemia after a meal and to develop a sustainable hypoglycemia correction strategy.
Gastric emptying measured with scintigraphy in patients after standard Roux-en-Y Gastric Bypass (S-RYGB), Banded-RYGB (B-RYGB) or Extended pouch-RYGB (E-RYGB).
Studies of appetitive behavior in humans after RYGB have produced ambiguous results. It therefore remains unclear whether there are fundamental shifts in the palatability of high-fat and sugary foods after RYGB or simply a decrease in the appetitive drive to ingest them. Moreover, learning processes may play a role as changes in diet selection progress with time in rats after RYGB. However, direct measures of an altered food selection in humans after RYGB are rare and both the durability of the phenomenon as well as the role of experience for changes in food selection remain elusive.
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.
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.
The primary objective of this study is to assess the neuro-endocrine response to hypoglycaemia in PHH vs. non-PHH post-gastric bypass individuals.
The primary objective of this study is to assess the effect of the natural course of postprandial hypoglycemia vs. a postprandial euglycaemic condition on driving performance in individuals with confirmed postprandial hyperinsulinaemic hypoglycaemia after gastric-bypass surgery.
The purpose of this observational registry is to evaluate the safety and performance of the easyEndoTM Universal Linear Cutting Stapler and reloads from Ezisurg Medical used in laparoscopic RYGB surgery to create anastomoses. The goal of the study will be achieved by assessing the device performance and reporting of peri- and postoperative complications in a prospectively maintained database.
