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…
Condition: Cancer / Multiple Myeloma
Investigator: Yvonne Saenger, MD
Status: Closed
The purpose of this study is to test two imaging techniques, one called whole body diffusion weighted magnetic resonance imaging (WB-DWI MRI), and another called F-18 3-deoxy-3-fluorothymidine PET (F-18-FLT PET). The goal is to see whether these imaging techniques would allow the study doctors to see changes in the size of a tumor earlier for patients with…

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…

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…

Investigator: Richard Sloan, PhD
Status: Closed
This study focuses on the effects of aerobic conditioning on cognition and brain activity. Eligible participants will complete an exercise stress test, MRI, and cognitive testing session at the beginning and end of the study. Once participants complete the first set of appointments, they will be randomly assigned to one of two conditions for 12-weeks.…
Condition: Healthy Volunteers
Investigator: Stephen Arpadi, MD, MS
Status: Closed
We are seeking healthy volunteers (HIV-negative) for a study seeing if HIV is associated with faster biological aging among older African American adults, whether faster biological age is related to health conditions that typically occur in older people and whether these conditions might be due to stress or over-activity of certain parts of the immune…
