Clinical trials

Changes in taste and smell can occur during chemotherapy treatment. These chemotherapy-related side effects can negatively impact patients' quality of life and diet. The aim of this research is therefore to propose a solution to alleviate these taste and smell disorders. Based on the same principle as rehabilitation proposed for anosmia (loss of smell) related to COVID-19, we hypothesize that olfactory rehabilitation (using the sense of smell) through the odorous properties of essential oils could be effective for chemotherapy-related taste and smell alterations.

Surgery is one of the management options for type 2 diabetes in patients with moderate obesity. This is a recent option because it has been part of the recommendations since October 2022. The possible surgical techniques are the same as those for bariatric surgery: * Sleeve, * Bypass, * Gastric band, but the main goal is not weight loss, it is remission of type 2 diabetes. It is called metabolic surgery. The ring technique (gastroplasty) is practiced less and less in France because it is less effective in weight loss and is responsible for major discomfort. Currently, metabolic surgery is one of the recommendations but no study has compared the effectiveness of the techniques with each other. One or other of the techniques can be chosen according to the preferences of the surgeon, the patient, the center, etc. but this choice is not made objectively, in the absence of comparative data. This study would like to follow up on patients for whom metabolic surgery has been proposed by the doctor,. If the surgery is accepted, this study would like to improve knowledge of the effectiveness of the different techniques, and thus demonstrate which metabolic surgery technique is preferred in terms of effectiveness and safety.
