NCT03581305
Background: Human immunodeficiency virus (HIV) infection is a serious disease with no cure. Some people with HIV have depression and other mood problems. They can have problems with thinking and memory. Researchers think 2 chemicals in the brain may cause those problems. The chemicals are serotonin and dopamine. The researchers want to take images to learn more about those chemicals in HIV patients. Objective: To learn how HIV affects serotonin and dopamine in the brain. Eligibility: Adults ages 18-70 with HIV who have been on antiretroviral treatment for at least 1 year Healthy adults ages 18-70 All participants must be already enrolled in protocol 13-N-0149. Design: * Participants will be screened with a urine drug test. The results could be shared with insurance companies. * Participants who could be pregnant will have a pregnancy test. * Participants may have a physical exam and blood tests. * Participants will have 1 or 2 positron emission tomography (PET) scans. A needle will guide a thin plastic tube (catheter) into an arm vein. A radioactive drug will be injected into the plastic tube. This is a tracer that helps researchers understand the PET images. * Participants who have the dopamine scan will have to fast for 4-6 hours before the scan. They will take a pill to help direct the tracer to the brain one hour before the scan. * Each scan will last about 1.5 hours. * Participants will be asked to drink a lot of fluids and empty their bladder frequently for the rest of the day after each scan.
NCT05777044
The goal of this clinical trial is to determine the effects of a 10-week (2x a week; 45-minute per session) Hatha yoga intervention in adults ages 18-25 (n = 45) on mental health outcomes. The main questions it aims to answer are: What is the effect of a hatha yoga intervention on depression and anxiety symptoms? What is the effect of a hatha yoga intervention on electroencephalogram (EEG) alpha and theta band power? What is the effect of hatha yoga intervention on heart rate variability? Participants will be randomized to three groups: waitlist control (usual routine), Hatha yoga (experimental group), and meditation (active comparative group). Participants in the Hatha yoga experimental group will attend 10 weeks of twice-weekly 45-minute yoga sessions. The active comparison meditation group will participate in 10 weeks of twice-weekly 45-minute meditation sessions. The control group will continue with their usual routine. Researchers will compare changes in depression and anxiety symptoms, EEG alpha and theta band power, and heart rate variability between the three groups.
