Adults with Knee Pain Sought

We are studying how muscle weakness around the knee may lead to changes in kneecap motion and pain. Compensation is provided. Learn how to participate by contacting the Clinical Center Office of Patient Recruitment at 1-866-444-2214 (TTY 1-866-411-1010) or Refer to study 13-CC-0099. Read more online at

Study Needs Healthy Children

NICHD seeks healthy children 7 to 11 years old with above average weight to join in a research study. Researchers want to learn if breaking up sitting with short periods of activity improves children’s metabolism and attention. Six outpatient visits on consecutive days of about 3 hours each (Monday- Friday, early evening and Saturday morning) are required. Compensation will be provided. For more information, call 1-866-444-2214 (TTY 1-866-411-1010). Read more at Refer to study 17-CH-0130.

VRC Recruits Healthy Volunteers

Vaccine Research Center researchers seek healthy volunteers, 18-50 years old, for a study evaluating an investigational vaccine that targets HIV. Compensation is provided. There is no risk of infection. To learn how to participate, call 1-866-833-5433, email or visit

Volunteers with Diarrhea Needed

The National Institute of Nursing Research invites volunteers of all ages experiencing diarrhea to participate in a research study. Many people suffer from diarrhea every year. In the United States, it leads to about 130,000 hospitalizations and 3,000 deaths a year. Researchers want to test whether a research tool detects pathogens (for example bacteria) that cause diarrhea. The study involves one outpatient visit that may last 2-3 hours and stool sample collection. No compensation will be provided. All study-related tests will be provided at no charge. Parental consent is required for minors. For more information about study 18-NR-0040, call 1-866-444-2214 (TTY 1-866-411-1010) or visit
