The goal of this early feasibility study is to gain initial insight into the basic safety and performance of transluminal (through the blood vessels) implantation of the PASCAL System's implant (composed of man-made materials). We are trying to evaluate the safety and performance of the PASCAL System with Optimal Medical Therapy (OMT) (also known as…
This is a research study for patients who have Tricuspid Regurgitation (TR), a condition that occurs when the three leaflets of the heart's tricuspid valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood…
The Columbia Otolaryngology Department is interested in understanding the intersection of vaping, smell, and taste and their impact on individuals' preferences for certain flavors. Participation will involve answering a series of questionnaires in addition to completing a formal evaluation of your smell and taste with standardized measurements. You can…
This study is for individuals who have Cushings disease and want to join voluntarily in this study to find out if a study drug called osilodrostat (LCI699) is safe and has beneficial effects in people who have Cushings disease. Cushings disease is a rare but debilitating disease. Cushings disease is caused by a benign tumor of the pituitary gland. The tumor…
The purpose of this study is to determine if measuring blood levels of proteins called POMC, AgRP, and chromogrannin A (CGA) can be used to diagnose and track tumor growth and recurrence in patients that have ACTH-dependent Cushing's syndrome, non-secreting pituitary tumors, and other neuroendocrine tumors. We invite you to participate if you have: a…
The Edwards Cardioband Tricuspid Valve Reconstruction FIT valve repair system is a prospective, single arm, multi-center study to evaluate the safety and performance of the Cardioband Tricuspid System. The Edwards Cardioband Tricuspid Valve Reconstruction System is intended for patients with tricuspid regurgitation deemed to be potential candidates for…
This is a prospective, single-arm, multi-center, early feasibility study. This research study is for patients who have Tricuspid Regurgitation (TR), a condition that occurs when the three leaflets of the heart's tricuspid valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart…
The use of electronic cigarettes, also known as e-cigs or vaping, has increased among former smokers and young adults who have never smoked. Relatively little is known, however, about their health effects (whether they are adverse, have no effect, or are beneficial). The purpose of this research study is to evaluate (1) the association of e-cig use with…
This is a research study for patients who have Tricuspid Regurgitation (TR), a condition that occurs when the three leaflets of the hearts tricuspid valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood forward.…
This is a four-session study in which we will be recruiting existing cigarette smokers to explore the competitive dynamics between memory encoding and memory retrieval. To participate, you will first go through a phone screening to determine eligibility and learn about the study. Then you will be asked to visit our facility at the Morningside Campus of…
The purpose of this study is to confirm the effectiveness and safety of LCI699 in treating patients with Cushing's disease. Patients will be treated with the invesitigational drug LCI699 at doses up to 60 mg a day, and possibly for a short period of time with placebo. A placebo is a dummy drug ("pill") with no active medicine inside.
