Clinical Trials

The Bashir™ Endovascular Catheter has been designed to administer therapeutic agents in the peripheral vasculature. Because of the unique design of the catheter, with its six expandable infusion limbs, the Bashir™ Endovascular Catheter has the ability to: 1. Create a much larger central channel for blood flow, thereby utilizing the body's own endogenous fibrinolytic agents to lyse the clot, and 2. Greatly enhance the radial dispersion of a catheter-administered thrombolytic agent throughout the thrombus. Expansion of the multiple arms of the basket in the infusion catheter causes fissuring of the clot. The net result is that a greater surface area of clot is exposed to both endogenous and exogenously administered lytic agents, thereby promoting clot dissolution.

Do you or your child have a platelet, bleeding, or white blood cell disorder? This study is looking at people who have platelet or other blood disorders. The researchers will use a blood sample to look for problems with platelets and a possible genetic cause in the participant’s DNA or RNA. To participate in this study, you must be a child or adult who either is healthy or has a platelet disorder, coagulation disorder, or white blood cell disorder. This study is located in New York, New York.

Are you an adult willing to give blood samples? This study investigates ways to prevent blood clotting in people with sickle cell disease. In this population, blood clotting is the most common cause of vascular death after heart attack and stroke. Scientists are studying the blood of people with sickle cell disease and comparing it with the blood of people without sickle cell disease over 2 years. To participate in this study, you must be between the ages of 18 and 80 years old and willing to participate for up to 2 years. This study takes place in Bethesda, Maryland.

To determine the mechanism of monocyte priming in humans, the study team will conduct a complete feeding trial in normal weight and metabolically healthy human subjects (20-45 years of age) using a western diet (WD), characterized as being high-saturated fat, high-fructose, and high-calorie for 8 weeks.

The Together Everyone Achieve More (TEAM) Physical Activity trial evaluates the efficacy of a group-based social affiliation intervention (vs. a standard group-delivered physical activity comparison program) for increasing physical activity among inactive African American women. Using a group cohort randomized design implemented at community centers across five years, the primary aim of this study is to evaluate the efficacy of the 10-week TEAM-PA group-based intervention (vs. comparison program) on increasing daily total physical activity from baseline to post-intervention and maintenance at a 6-month follow-up.

The study aims to determine the minimally effective dose combination(s) of frequency and duration needed to provide cardiometabolic benefit during an 8-hour experimentation period.

This study will identify and test the physiological effects of several sedentary behavior interruption strategies and explore the feasibility (i.e., likelihood of an individual performing the requested activities) of those strategies to inform the development of public policy surrounding sedentary behavior interruption. Long-term, the findings of this study will inform a large clinical trial that can test whether sedentary behavior reduction can decrease cardiovascular disease risk.

This study aims to evaluate the effect of estradiol with or without a prior gonadotropin releasing hormone analogue on insulin sensitivity and vascular function in transgender females compared to cisgender controls.

The purpose of the study is to evaluate how dietary habits in the post-surgical year impact outcomes of bariatric surgery.

The overarching goal of the proposed study is to develop and test an enrichment to Nurse-Family Partnership (NFP) using an existing, evidence-based program to improve clients' and their children's cardiovascular health from early pregnancy to 24 months postpartum. With support from NFP supervisors and nurses, the investigators will develop new NFP materials promoting healthy diet, activity, sleep, and smoking behaviors, along with optimal weight, glycemia, lipid, and blood pressure profiles. The investigators will conduct a pilot study with 40 prenatal or postpartum NFP clients and their nurses to determine feasibility and acceptability of the materials and study protocol.
