We are conducting a research study on the effect of high insulin levels on the buildup of excessive liver fat ("fatty liver disease") in people at risk for type 2 diabetes. We are seeking adult volunteers, ages 18-65, who have obesity with a body mass index of 30-45, and have been diagnosed with, or are at risk for, prediabetes and metabolic…
We are researchers at Columbia studying the learning and decision making. We are looking for participants over the age of 18, who have been prescribed Trizepatide for weight loss. Participants will be asked to complete an MRI scan and play computer games. Participants earn $25 per hour. Help us understand how the GLP-1 agonists affect brain and cognition!
The Physiology of the Weight Reduced State (POWERS) is a national research study designed to discover and learn what happens to the human body after weight loss and to learn why some people regain their lost weight. Understanding why this happens could help health professionals improve strategies for successful weight loss maintenance after weight loss.…
The purpose of this study is to evaluate if genetic variations are associated with the amount of weight loss with diet and while taking an FDA-approved medication for weight loss. The participation lasts ten months and includes six in-person visits at CUIMC with blood sampling and questionnaires, virtual nutritional counseling, and taking an oral weight…
The purpose of this study is to research and evaluate safety and effectiveness of the administration of bone marrow mesenchymal stem cell (bmMSC) derived extracellular vesicles product, DB-3Q, the study drug for perianal fistulizing Crohns disease. The study will enroll up to 36 participants across multiple sites. Your participation in this study will be…
The Takeda study drug used in this study is vedolizumab, a monoclonal antibody. Monoclonal antibodies are proteins made in laboratories that act like proteins in our bodies called antibodies. Vedolizumab acts specifically in the gut and works by preventing certain immune cells from going to the gut and helps reduce inflammation that can cause the symptoms (…
If your doctor has determined that you have a diagnosis of Ulcerative Colitis (UC), you may qualify for treatment with Sacral Nerve Stimulation (SNS). The purpose of this study is to evaluate the safety and effectiveness of SNS in study participants who have UC. While the investigational medical device used in this research study has been studied and…
We are conducting a research study on how insulin controls blood sugar in both healthy people and those at risk of type 2 diabetes. We are seeking adult volunteers, aged 18-65, who have body mass indices either in the lean range (18-25 kg/m2) or in the obesity range (30-45 kg/m2) but who do not have prediabetes or diabetes. Participants will undergo a…
We are recruiting volunteers, aged 18-70, for a research study on the buildup of excessive liver fat ("fatty liver disease") in people with or at risk for type 2 diabetes because their bodies are resistant to the actions of the blood sugar-lowering hormone, insulin. To do this, we seek to temporarily induce or accentuate insulin resistance in 14…
We are seeking adult volunteers with body mass index in the obesity range (30-45 kg/m2) to come in for a single study visit where they answer some health questions and have a small volume of blood drawn (25 cc/1.7 tbsp). We will measure levels of the blood sugar-lowering hormone insulin as well as glucose (sugar), certain fats, and other molecules related…
