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…
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 are doing this study to test the use of a drug called bromocriptine for women with a condition called Peripartum cardiomyopathy (PPCM). The study will look at how the heart muscle improves in women taking bromocriptine compared to a group of women given a placebo or inactive pill.
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…
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 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…
The purpose of this study is to determine the safety and long-term effects of CK-3773274 and to learn how well it is tolerated at different, increasing dose levels in participants with HCM.
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.
The purpose of this outpatient study is to examine if oral Spironolactone (100mg/day) in addition to loop diuretics (water pills) can improve signs and symptoms of fluid retention in patients with heart failure and prevent hospitalization.
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.
This research study will evaluate the effectiveness of CEP-417 (Mesenchymal Precursor Cells (MPCs)) when administered through an injection catheter to your heart muscle improving your symptoms, helping your heart function better, improving your quality of life, and in reducing the number of times you may need to be hospitalized due to your heart failure.…
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.
The purpose of this trial is to determine if people with impaired heart function, that may have been induced with chemotherapeutic drugs and/or radiation, will have improved heart function with a cardiac device that can pace the heart more efficiently using cardiac resynchronization therapy.
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…
The purpose of this study is to compare the effect of the investigational drug, Mavacamten, to a placebo (an inactive drug). This is being done to evaluate whether Mavacamten is safe in obstructive Hypertrophic Cardiomyopathy (HCM) patients and helps to improve symptoms or ability to exercise. Mavacamten is an investigational drug. This means that it has…
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.
