NCT05008991
The COVID-19 pandemic has presented considerable challenges to global health services and dictates almost every aspect of medical practice and policy. The menopausal transition may have significant consequences for respiratory health as COVID 19 symptoms subsides, lung function testing should be done to assess the consequences of this virus on lung health especially in menopausal woman.
NCT05106660
In the era of laparoscopic surgery, day case procedures are increasingly practiced around the world, however, day case bariatric surgery remains a controversial issue due to lack of sufficient evidence evaluating its safety. Laparoscopic sleeve gastrectomy (LSG) is currently the most popular bariatric surgery performed worldwide, and the standard is 1-2 days postop stay. However, the American College of Surgeons and the American Society for Metabolic and Bariatric Surgery released guidelines in 2016 that allowed LSG in ambulatory surgery centers for low acuity patients. In the present trial, investigators will compare the safety and feasibility of same day discharge vs next day discharge in a large group of patients undergoing laparoscopic sleeve gastrectomy.
NCT02789553
Despite an impressive capacity to induce diabetes remissions, the gastric bypass surgery has been associated with the onset of hyperglycemic peaks, which are very intensive and transient, in formally non diabetic patients. The aim of this study is to study the digestion of starch as compared to that of glucose (same glucose load) before and after gastric bypass surgery in obese patients. Volunteers will be recruited among the candidates to a gastric bypass, and will be studied before and 3 months after surgery. They will have on each occasion 2 random meals, corresponding to 30g glucose, one made of starch the other made of glucose, both naturally labeled with 13C. The digestion of starch will be assessed with the increase in the plasma 13C-glucose tracer. Plasma samples will be collected for 3 hours. Some studies have already investigated time of absorption of glucose, but any study has examined the time of digestion of glucose. Other study always used glucose syrup, so they cannot have results about digestion. It is the reason why, in this study, glucose syrup and a starch meal will be taken by the same patient and glycaemia will be compared. In this way, results will be obtained about the kinetic of digestion of starch.
