Condition: Obesity
Investigator: Ilene Fennoy, MD
Status: Currently Recruiting
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…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
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…
Condition: Obesity
Investigator: Daphna Shohamy, PhD
Status: Currently Recruiting
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!
Condition: Obesity
Investigator: Faris Zuraikat, PhD
Status: Currently Recruiting
The purpose of this study is to assess energy balance during two different diet periods.
Condition: Obesity
Investigator: Rudolph Leibel, MD
Status: Currently Recruiting
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.…
Condition: Obesity
Investigator: Judith Korner, MD
Status: Currently Recruiting
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…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
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…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
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…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Currently Recruiting
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…
Condition: Surgery
Investigator: Bret Taback, MD
Status: Closed
The purpose of this study is to test an investigational device called the Echopulse for treatment of breast fibroadenomas in women. Fibroadenomas are benign (noncancerous) breast tumors. These lumps can occur alone, in groups, or as a complex of lumps together. Sometimes women feel these in the breast when doing regular self-breast exams, or they may be…
Condition: Obesity
Investigator: Joshua Cook, MD, PhD
Status: Closed
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…
Condition: Surgery
Investigator: Marcos Vidal Melo, MD, PhD
Status: Closed
We are asking you to participate in a research study to learn if different ways of doing routine anesthesia and patient care before, during and after abdominal surgery can reduce breathing problems. The total time of the study is 3 months with daily visits by a member of our study team while you are in the hospital and 3 short follow-up calls after you…
Condition: Vascular Conditions / Ischemia
Investigator: Sahil Parikh, MD
Status: Closed
The objective of the LIFE-BTK RCT is to evaluate the safety and efficacy of the ESPRIT BTK device (which is a bioresorbable polymeric scaffold with the everolimus drug and a bioresorbable polymeric coating mounted on a balloon dilatation catheter) compared to Percutaneous Transluminal Angioplasty (PTA), which is is a procedure that can open up a blocked…
Condition: Surgery
Investigator: Nicholas Morrissey, MD
Status: Closed
You are being asked to be part of this study because you have been diagnosed with a bulge or aneurysm in your iliac arteries, the vessels that supply blood to the lower half of your body. As an aneurysm expands, the walls become weak and may rupture, causing a major loss of blood with a high risk of death and other serious complications. To avoid this risk…
Condition: Surgery
Investigator: William Levine, MD
Status: Closed
The study is designed to evaluate the safety and effectiveness of the InSpace device as a primary surgical treatment for a full thickness Massive Rotator Cuff Tears (MRCT) in comparison to Partial Repair of a full thickness MRCT performed during an arthroscopic procedure.
Condition: Surgery
Investigator: Danielle Bajakian, MD
Status: Closed
The purpose of this research study is to compare the safety and effectiveness of two drug-eluting stents that are used to open the blocked or narrowed blood vessel of the leg in patients with Peripheral Artery Disease (PAD): the ELUVIA Stent and the Zilver PTX Stent.
Condition: Surgery
Investigator: Michael Argenziano, MD, FACS
Status: Closed
Thepurposeof the study is to test whether or not QPI-1002 could be used to lessen or prevent acute kidney injury after heart surgery. Another purpose is to better understand the safety of QPI-1002.
Condition: Surgery
Investigator: Jeffrey Geller, MD
Status: Closed
The purpose of this study is to evaluate the short-term (1 year) and long-term (5 and 10 year) safetyand effectiveness of the JOURNEY II CR Total Knee System in patients with degenerative joint disease of the knee requiring primary total knee replacement. Clinical, radiographic, and health economic outcomes will be evaluated.
