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 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…
This is a randomized controlled trial (RCT) that will compare the clinical outcome of MitraClip device versus surgical repair in patients with severe primary MR who are at moderate surgical risk and whose mitral valve has been determined to be suitable for correction by MV repair surgery by the cardiac surgeon on the local site heart team. In this trial,…
The study is designed to compare the safety and effectiveness of the PASCAL System to the MitraClip System for reduction of degenerative mitral regurgitation.
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 testing new experimental drugs such as selinexor in the hopes of finding a treatment that may be effective against tumors that have come back or that have not responded to standard therapy. The goals of this study are: To find the highest safe dose of selinexor that can be given without causing severe side effects; To learn what kind of side effects…
This study is designed to look at the safety and performance of The Intrepid TMVR System using transfemoral transseptal access (TF). TF is a procedure that requires access to the femoral vein by an incision in the lower limb between the knee and the hip. The study population is for patients with severe, symptomatic mitral regurgitation (MR), a condition…
The Millipede Feasibility Study is a prospective, open-label, single-arm study to assess the safety and feasibility of the Millipede Transcatheter Annuloplasty Ring System in subjects with functional mitral regurgitation. The Millipede Annuloplasty Ring System is a novel transcatheter, fully adjustable, complete annuloplasty repair device for the treatment…
