This study seeks to understand if the medication pramipexole improves social connectedness and functioning in adults (ages 18-50) who experience anxiety or depression. The study plans to enroll 108 participants total across two sites (University of California San Diego and New York State Psychiatric Institute). Pramipexole will be given in a 6-week randomized, double-blind, placebo-controlled trial. Social reward processing will be assessed using measures of brain function (fMRI), behavior, and self-report at baseline and week 6. Knowledge gained from this study will help determine the therapeutic potential of targeting the dopamine system to remediate social disconnection as an anxiety and depression intervention.

There is a high prevalence of anxiety and depression in patients with Type 2 Diabetes (T2D). While past studies demonstrate the potential therapeutic effect of mindfulness-based interventions in patients with T2D, little is understood about the mode of delivery or quantity of the intervention necessary to experience benefits. This project aims to develop and implement a self-compassion tool kit based on the principles of mindfulness and meditation to better understand how self-compassion works to affect psychological health and wellbeing in patients with T2D. The investigators will study the impact of a self-compassion tool kit - including mindfulness meditation, exercise, journaling and sleep parameters - on T2D. Enhancing emotional well-being could complement current T2D treatments to facilitate improved quality of life. Type: Interventional Start Date: Jul 2024 |

The main goal of the present study is to determine if a smoking cessation program designed for people living with certain chronic conditions and delivered via videoconferencing groups works better than a control condition--a program that is not designed to help with smoking but that does have the same number of group contact hours as the other program (this program is called the Attention Matched Control condition; AMC) for helping people with certain health conditions stop smoking. People in both groups will receive brief advice to quit and an offer of nicotine replacement therapy patches (NRT), as well as 12 videoconferencing group sessions. The team will measure smoking behavior over a one-year period and compare smoking rates for the treatment condition against AMC to see if the treatment condition is better at getting people living with certain health conditions to quit smoking.

The goal of this clinical trial is to compare, at 3 months, the effects of a yoga intervention on physical health, including balance, muscle strength, physical activity levels, cardiac autonomic function, and physical vulnerability, as well as psychological health, including depressive symptoms and anxiety, in cardiac patients who are older than 65 years old and randomized to the intervention or control group. The main questions aim to 1) determine if yoga can improve physical health outcomes such as balance, muscle strength, cardiac function, and physical vulnerability in older adults with cardiovascular disease, and 2) determine if yoga can positively impact psychological health, including reducing depressive symptoms and anxiety in this population. Participants in the intervention group will attend yoga sessions twice a week for three months. The intervention group will be asked to complete surveys and physical function assessments at the beginning and three months later. Researchers will compare the intervention group and the control group to see if there is any difference and improvement in physical and psychological health between the two groups.

Background: Diet is one of the most modifiable behaviors affecting health. But diet assessment measures that are based on self-report can be inaccurate. Researchers want better ways to address the role of diet in chronic disease. They want to see if stable isotopes can be used to better assess what people eat. Objective: To see if stable isotopes can help scientists identify things people eat. Eligibility: Healthy adults ages 18 to 65 Design: Participants will be screened with a medical history and physical exam. They will have blood and urine tests. These tests will be repeated during the study. Participants will stay in the inpatient unit of the NIH in Phoenix, Arizona, for 13 weeks. For 7 days, participants will eat a diet prepared by the NIH kitchen. They will get balanced meals that are 50% carbohydrates, 20% protein, and 30% fat. Then participants will be randomly placed on one of 3 diets containing different percentages of carbohydrates from soda. Participants height and weight will be measured. The amount of fat and muscle in their body will be measured by body scans that are similar to x-rays. Participants will have oral glucose tolerance tests. They will consume a sugar drink and then give blood samples over 3 hours. Participants will give hair and stool samples. Participants will complete a diet questionnaire. It assesses their food intake over 24 hours. Participants will complete behavioral questionnaires and computer performance tests. Participants will have fat biopsies taken from their stomach and thigh. Participants will have three 24-hour stays in a metabolic chamber. It is used to measure metabolism.

Deficits in cognitive control are core features of late-life depression (LLD), contributing both to emotion dysregulation and problems with inhibiting irrelevant information, conflict detection, and working memory. Clinically characterized as executive dysfunction, these deficits are associated with poor response to antidepressants and higher levels of disability. Improvement of cognitive control network (CCN) dysfunction may benefit both mood and cognitive performance, however no current pharmacotherapy improves Cognitive Control Network deficits in LLD. The study examines the hypothesis that nicotine acetylcholine receptor agonists enhance Cognitive Control Network function. This effect may resultantly improve mood and cognitive performance in LLD. Small, open-label studies of transdermal nicotine (TDN) patches have supported potential clinical benefit and provided support that transdermal nicotine administration engages the Cognitive Control Network. This blinded study will expand past open-label trials supporting potential benefit in LLD. It will examine TDN's effect on depression severity and cognitive control functions measured by neuropsychological testing. The study will evaluate 60 eligible and enrolled participants over a 3-year period. Type: Interventional Start Date: Apr 2023 |

Other tests will include: Spirometry: Participants will breathe in and out through a mouthpiece to measure how much air they can hold in their lungs and how hard they can breathe. Diffusion capacity of lungs for carbon monoxide: Participants will breathe in a gas that contains a small amount of carbon monoxide. Then they will breathe through a mouthpiece. This test measures how well oxygen moves from the air into the blood. Resting energy expenditure. Participants will lie still for 30 minutes with a clear dome over their head.
