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…
Genes and Environment in MS (GEMS) is a longitudinal cohort study investigating how genetics and environment can lead to the onset of Multiple Sclerosis. We are recruiting first-degree relatives (siblings, parents, and children) of people who have been diagnosed with MS. This study involves the collection of magnetic resonance imaging (MRI) of the brain,…
MS Genetics aims to better understand the genetic component of demyelinating diseases by doing genetic testing on blood samples of participants. This study involves a one-time blood draw and completion of questionnaires spread out over a couple of years in hopes to better understand the genes that makes one predisposed to Multiple Sclerosis and various…
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 Snapshot study aims to understand brain and spinal cord aging in healthy individuals and individuals with multiple sclerosis (MS). We aim to identify new tools that will help us to achieve successful brain aging in the general population and in people with an underlying autoimmune disease. A critical aspect of this study is that we are looking for…
The purpose of this study is to evaluate the differences between immune profiles of individuals remaining on Ocrelizumab/Rituximab versus those transitioning to diroximel fumarate at two years. Baseline visits for subjects transitioning to diroximel fumarate (DRF) will take place 6 months after last Ocrelizumab (OCR) or Rituximab (RTX) dose, prior to…
We are currently recruiting individuals with Multiple Sclerosis (MS), first-degree family members of persons with MS, and healthy individuals to take part in our research on the effects of probiotics. Our goal is to better understand how the health of the gut microbiome influences the immune system.
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…
This study will be used to evaluate the immunologic effects of Prebiotics (soluble fiber required by beneficial bacteria), in comparison to Probiotics (beneficial bacteria), in individuals with Multiple Sclerosis (MS) and Clinically Isolated Syndrome (CIS).
ASPIRE is a clinical trial to investigate aspirin as a treatment to improve exercise performance in people with multiple sclerosis (MS) who experience overheating during exercise. Persons with multiple sclerosis benefit from exercise, but many avoid it because of exhaustion and overheating. This randomized controlled trial (RCT) tests aspirin as a method to…
The purpose of this study is to evaluate the safety, tolerability and effectiveness of a study drug called ISIS-396443 when using it to treat children with later-onset spinal muscular atrophy (SMA). SMA is a neuromuscular disease that causes a degeneration (a breakdown) of the motor neurons in the spinal cord, resulting in a weakening of the muscles in…
Our clinic is currently participating in the Brave Trial, a clinical research study for Duchenne muscular dystrophy (DMD). This study is being conducted to learn whether a study drug can improve motor functions in boys with DMD. If your child takes part, he'll receive at no cost: study drug or placebo, study-related procedures, reimbursement for…
Moving forward in Charcot-Marie-Tooth disease. A clinical research study assessing the safety and effectiveness of an investigational product in people with Charcot-Marie-Tooth (CMT) disease experiencing muscle cramps is now enrolling. Participation is entirely voluntary. Contacting us does not mean that you are required to take part in this study. If you…
The purpose of this study is to see if ocrelizumab (study drug) will stabilize, or potentiallyimprove the signs and symptoms of your MS. Ocrelizumab is a type of drug called amonoclonal antibody. Monoclonal antibodies act like your bodys immune system andattach to certain cells in order to attack germs and other illnesses in your body.Ocrelizumab attaches…
This study is for infants that have been genetically diagnosed with Spinal Muscular Atrophy (SMA) and are currently not showing any signs or symptoms of the disease. The purpose of this study is to see whether ISIS 396443 has any effects (good or bad) on infants with SMA (who do not yet show signs or symptoms of the disease) and to see if ISIS 396443 can…
The purpose of this study is to find out if eteplirsen can help people with the muscle disorder called Duchenne Muscular Dystrophy (DMD) and find out if eteplirsen is safe to take without causing too many side effects. Eteplirsen is an investigational (experimental) drug and can only be used in research studies. DMD is caused by a mutation (a change) in the…
