Bariatric surgery and a once-weekly glucagon-like peptide-1 medicine both cause major weight loss in teens, but their effects on mouth and gut bacteria and on damaged blood fats tied to metabolism are still unknown. This study will collect saliva, stool, and routine blood samples from adolescents before treatment and six months later to see how these…
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…
Pancreatic cancer is a deadly disease and the best hope for improving the chances of survival is to find it early. Some patients, called "high risk", have an inherited predisposition to pancreatic cancer. Certain medical centers have started programs where "high risk patients" undergo testing, such as receiving imaging scans, to look for…
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…
We're conducting a research study on how much insulin is needed to control blood sugar in people who are made temporarily resistant to insulin's effects. Insulin is the main hormone (chemical signal) that the body uses to lower the levels of sugar in the blood. We are interested in looking at insulin levels because we think that lowering insulin…
We are inviting patients with active Rheumatoid Arthritis (RA) to help us better understand how treatment options affect inflammation in soft tissues. With a combination of blood work, a full-body FDG PET-CT scan, questionnaires, and a soft tissue biopsy (from an area around the belly button), we hope to see how RA interacts with these multiple areas of…
The purpose of this study is to evaluate how safe and effective the NanoKnife System is at treating Stage 3 pancreatic adenocarcinoma. This is registry study and therefore, the NanoKnife System is not being used for study purposes. The safety and efficacy of this system will be evaluated by comparing survival rates, pain ratings, and number of adverse…
The purpose of this study is to learn which treatment works best in patients with pancreatic cancer. The study explores multiple treatment combinations. A study drug called atezolizumab may be combined with other drugs such as cobimetinib, PEGPH20, and BL-8040. Patients may also be assigned to receive standard chemotherapy treatment.
We are doing a research study to learn more about why people with rheumatoid arthritis (RA) are prone to heart disease. We are recruiting patients diagnosed with Rheumatoid Arthritis without a personal history of heart disease. This study involves one initial full visit as described below, and a brief follow up visit that will take place approximately 2 or…
This research study is being conducted to see if a new treatment using a study drug called Olaparib given after platinum based chemotherapy treatments can reduce the risk of pancreatic cancer from growing back. Participants will receive either Olaparib or placebo (no contains active medication) and will stay on the research study for as long as they are not…
The purpose of this study is to test whether GVAX pancreas vaccine and CRS-207 together are safe and work better than chemotherapy to treat individuals with advanced pancreatic cancer who have received at least one prior chemotherapy treatment for metastatic cancer. This study will also look at whether CRS-207 alone is safe and works better than…
The study aims to compare the effect two different RA treatments on cardiovascular health in patients who are considering a treatment change. The study is recruiting patients who are only taking methotrexate and are switching treatment due to a lack of improvement. The trial will randomize participants to take a TNF inhibitor (Enbrel or Humira) in addition…
The purpose of this study is to find out which doses of talimogene laherparepvec (T-Vec) can be given safely to patients with pancreatic cancer that is either too big to be taken out by surgery or has spread to other parts of the body. The study will also see if T-Vec can cause tumor shrinkage or prevent its growth. To find out which doses are safe, all…
