Osteoporotic fractures affect the lives of 1.5 million Americans each year. Imaging tests, such as bone density, are used to predict fracture risk and to help guide therapy for fracture prevention. In this study we are validating a high-resolution, three-dimensional scanner with the overall goal of improving the diagnosis of bone diseases.

This study is evaluating genomic screening in Ashkenazi Jewish and Hispanic communities. Genomic screening is done by collecting a blood sample and looking at a person's genes to learn if they are at high risk for certain health problems like cancer or heart disease or are at risk to have a child with a genetic condition. The study is designed to…

One of the consequences of donating blood is iron deficiency. In this study, we will screen healthy frequent blood donors for iron deficiency. We will enroll iron deficient donors and randomize them to intravenous iron treatment or placebo in order to determine whether iron deficiency has any harmful effects on the blood supply and the donors themselves.

Investigator: Adam Brickman, PhD
Status: Closed
This study is associated with the Alzheimer's Disease Research Center (ADRC) at Columbia University. The study seeks to understand changes in the way the brain's structure and function are related to age, and the risk of developing memory problems, Alzheimer's disease (AD), and dementia. The study will use magnetic resonance imaging (MRI) to…

Investigator: Loren Gianini, PhD
Status: Closed
The goal of this study is to better understand why some people have managed to lose weight and keep it off while others have not. We are recruiting people who have lost weight and kept it off as well as healthy non-dieters with overweight or obesity who are not trying to lose weight. Study participation involves computer tasks, brain imaging, and eating a…
Condition: Healthy Volunteers
Investigator: Blandine Laferrere, MD, PhD
Status: Closed
This pilot study is designed to examine the effect of a novel type of lifestyle intervention, administered via a smartphone app, on weight loss and improvement of metabolic health in individuals with overweight and/or obesity. A mobile application will be used to document eating behavior through photos. In addition, participants will receive personalized…

Investigator: Julie Franks, PhD
Status: Closed
Almost 40,000 people get HIV in the U.S. each year and almost all infections occur via sexual contact, especially male-to-male contact. The number of new infections has decreased slightly each year; however, we need other HIV prevention tools, including an effective HIV vaccine, to better protect people from HIV infection. An HIV vaccine is the best long-…
Condition: Heart Disease / Valve Disease
Investigator: Martin Leon, MD
Status: Closed
The goal of this study is to assess the safety and function of this new device to insert an artificial mitral valve. This study is for patients who are a high risk candidate for standard openheart surgery to treat their mitral regurgitation. The standard medical treatments generally available to patients with mitral regurgitation who do not undergo surgery…

Investigator: Sharon Wardlaw, MD
Status: Closed
This 2-phase study aims to explore ways to predict who will respond well to the FDA approved weight loss drug lorcaserin and to understand the mechanisms that develop which limit drug efficacy. Subjects will be recruited for a 5-week crossover study (phase 1) with lorcaserin and placebo followed by treatment with lorcaserin for 24 weeks (phase 2). Phase 1…
Condition: Heart Disease / Valve Disease
Investigator: Tamim Nazif, MD
Status: Closed
Are you scheduled for an interventional vascular procedure (e.g. BAV, TAVR/TAVI, EVAR or TEVAR) inorder to replace a damaged or failing valve? This research style studies the safety and efficacy of an Investigational Device (IDE) called the Cross-Seal Suture-Mediated Vascular Closure Device System. This device has not yet been approved by the FDA for use on…
Condition: Healthy Volunteers
Investigator: Micaela Martinez, PhD
Status: Closed
This study involves wearing a small light sensor on a lanyard and a temperature sensor in a wristband for one week in the summer, fall, winter and spring. The study will span 9 months. Participants will also be asked to fill out a daily questionnaire during those weeks. $30/week compensation or $120 in total for participation.

Take the Online Men's Health Survey (OMHS) today! Human Immunodeficiency Virus (HIV) and syphilis disproportionately affect men who have sex with men (MSM); however, this phenomenon is not well understood and is understudied in the United States. The OMHS study is being performed to help improve STI prevention and treatment services in the United…

Investigator: Magdalena Sobieszczyk, MD
Status: Closed
We are looking for healthy, HIV-negative individuals 18 to 50 years old who are interested in our studies that test antibodies for HIV prevention. Antibodies are one of the natural ways that our bodies fight or prevent infection. We are testing an antibody called VRC07-523LS against HIV. We will ask you to complete a brief questionnaire to find out if you…

The purpose of this study is to test whether an investigational drug called solanezumab can slow the progression of memory problems associated with brain amyloid. The study will also test 1) whether the anti-amyloid treatment can slow evidence of AD-related brain injury on imaging tests to look at brain structure and function and 2) the effect of…
