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…
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…
The Lugo Lab at Columbia University's Department of Psychiatry is conducting a study of extreme weather events and family functioning. We are recruiting mothers of children between 1-3 year old, who identify as Puerto Rican background, live in Uptown Manhattan or the Bronx and identify as low-income. You will be compensated for your time! All…
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…
Are you undergoing a stem cell transplant? You may be at high risk for infections after the transplant. This study is looking at the safety and effectiveness of an investigational medication for those who have undergone a stem cell transplant. Recovery after a stem cell transplant can already be challenging without the added worry of life-threatening viral…
This study is testing a drug called GDC-8264, which is being developed to treat acute graft-versus-host-disease (acute GVHD). GDC-8264 is an experimental drug, which means health authorities have not approved GDC-8264 in combination with standard medications for the treatment of acute GVHD. The purpose of this study is to evaluate the effects, good or bad,…
We are seeking children ages 7 - 12 to participate in a research study on irritability. The study consists of two lab visits. During the first lab visit, we will interview you and your child. During the second lab visit, your child will complete 3 tasks on the computer while electroencephalography (EEG) data are collected. We will also ask you to complete…
The purpose of this study is to see which study drug is the better treatment for CMV infection. The study also wants to see how safe the study drugs are. The study drugs are Maribavir and Valganciclovir. Those who participate in the study will not know which drug they are taking. The study team will not know either.
The purpose of this current study is to investigate the efficacy of a group model of Family Nurture Intervention in ameliorating behavioral problems in preschool-aged children. The behavioral, neurobiological and clinical insights gained from this project may eventually lead to better treatment of emotional, behavioral and developmental disorders. The…
In this trial, we will evaluate whether partially-HLA matched allogeneic multivirus-specific VSTs, will be safe and produce anti-viral effects in immunodeficient recipients infected with one of more of the targeted viruses that are persistent despite conventional anti-viral therapy. This will be in patients who have received a hematopoietic stem cell…
Parents! Join our research study! For families with 2-4 years olds, Complete from the comfort of your own home. Involves: Complete questionnaires; Collect a stool sample from your child; Provided with an easy to use kit and video instructions; Earn $25 for participating.
The primary objectives of this study are to measure the safety and effectiveness of bone marrow transplant (BMT) using specific chemotherapy in children with less severe SCD and to understand the long term effects of bone marrow transplant in children with SCD, by evaluating ovarian reserve, sickle cell related brain problems, sickle cell related kidney…
The purpose of this study is to see whether or not the medicine, Abatacept, when given after hematopoietic stem cell transplantation (HSCT) is effective in treating GVHD in children and adolescents with sickle cell disease (SCD). We are also planning to gather additional information about the safety of treating sickle cell disease with a hematopoietic stem…
This is a research study of a new drug for the treatment of new onset chronic graft versus host disease (cGVHD). Chronic GVHD is a complication that can occur after a stem cell or bone marrow transplant in which the newly transplanted donor cells attack the transplant recipient's body. The current way to treat cGVHD is to use prednisone (a type of…
The main purpose of the study is to find out about whether the study drug is safe in humans and aneffective treatment in pediatric patients with acute Graft versus Host Disease (GVHD). GVHD mayoccur after a bone marrow or stem cell transplant in which someone receives bone marrow tissue orcells from a donor (called an allogeneic transplant). The new,…
The purpose of this study is to test a new medicine to prevent liver venoocclusive disease (VOD) in patients undergoing hematopoietic stem cell transplant (HSCT) who are at high risk or very high risk for liver VOD following HSCT. Liver VOD can be a complication of bone marrow and/or stem cell transplant,which may be life threatening. The condition is a…
