Featured Studies

Diets worldwide include both processed and unprocessed foods. Researchers at the National Institutes of Health (NIH) in Bethesda, Maryland seek adult volunteers between 18-60 years old to participate in a study examining how processed and unprocessed foods affect metabolic health. Participants will be required to remain at the NIH Clinical Center for one 4-week stay and eat only the foods provided.

The National Institutes on Alcohol Abuse and Alcoholism (NIAAA) is recruiting heavy drinkers for a study to evaluate the safety of an investigational drug to treat signs and symptoms of alcohol associated liver damage. If you drink more than 20 alcoholic beverages per week, you may have this type of liver damage.

After stem cell transplantation, some people develop hard-to-treat anemia (low red blood cells) or thrombocytopenia (low platelets). Cytopenia(s) or low blood cell counts make you weak, prone to bleeding and bruising, and dependent on blood product transfusions. Researchers at the National Institutes of Health (NIH) are testing the drug fostamatinib to see if it is safe to treat cytopenia(s) after stem cell transplantation. A physician referral is not required to participate.

Healthy volunteers 18-60 years old are needed to test an investigational drug that was developed to reduce blood pressure in the lungs. The PAH team from @NHLBI hope that this investigational study drug may be helpful in treating patients with PAH in the future.

Do you... Find yourself constantly checking things? Spend lots of time ordering your belongings? Have unusual rituals or habits that seem unnecessary? Do you blurt out comments at inappropriate times, interrupt conversations or speak out of turn or feel you are overly impulsive? The National Human Genome Research Institute (NHGRI) is conducting an outpatient research study on the links between compulsivity, impulsivity and the developing brain in children and young adults.

Pharmacologic therapy with Bruton's tyrosine kinase (BTK) inhibitors is associated with an increased risk of heart problems like atrial fibrillation, bleeding, and high blood pressure (hypertension) which can lead to sudden death. There is currently no standard for cardiac screening or monitoring patients on BTK inhibitors. Researchers at the National Heart, Lung, and Blood Institute (NHLBI) are investigating the relationship between the development of heart problems in patients on BTKi as it relates to other variables.

Researchers are examining genetic and physical characteristics of the small vessel disease called CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy). They are enrolling volunteers to serve as healthy controls. Compensation is provided.

A research study at the National Institutes of Health (NIH) is is investigating how dietary habits affect our intestinal microorganisms by studying the effects of Mediterranean-like unprocessed (CLEAN-MED) diet. Participants will be divided into two groups, depending on their interest in trying out the diet for 4 weeks or maintaining a new healthy diet over months, and will be provided with some foods. Participants will log the food they eat and answer questions about their diet throughtout the study. Food and research supplies and procedures are provided at no cost.

A research study at the National Heart Lung and Blood Institute (NHLBI) is looking for pregnant women between 18 and 45 years of age who are at risk of having an infant with sickle cell disease and women who are pregnant with no risk of having an infant with sickle cell to donate their baby's cord blood. Tests and procedures provided at no cost. Travel may be reimbursed.

Dr. Kevin Hall and his team at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) are seeking male volunteers aged 18-65 and female volunteers aged 18-50 for a study on how low-carb (ketogenic) diets, with or without an investigational dietary supplement called Nicotinamide Riboside, impacts energy levels and metabolism during sleep.
