The goal of this clinical trial is to understand if genetic variations are associated with the amount of weight loss with diet and while taking an FDA-approved medication for weight loss. The main question[s] it aims to answer are: - In Aim One, the investigators propose to rigorously test the hypothesis that presence of the Taq1A A1+ polymorphism is associated with greater weight loss with NB compared with the A1- genotype. - In Aim Two, the investigators will explore other genetic polymorphisms that might influence the efficacy of NB such as the fat mass and obesity-associated (FTO) gene which modulates DRD2 signaling, as carriers of risk alleles in both the FTO and ANKK1 gene demonstrate altered responses to reward-learning tasks associated with negative outcomes. Participants will be in the study for 40 weeks, which consists of two phases: 1. From baseline to week 12, participants will receive individual nutritional counseling on a calorie restricted diet. This phase includes in-person visits, blood tests, an EKG, vital signs, questionnaires, body weight, and nutritional visits. 2. From week 12 to week 40, participants will continue to receive dietary counseling and will receive treatment with naltrexone/bupropion for 28 weeks. This phase includes in-person and phone visits, blood tests, vital signs, questionnaires, body weight, and nutritional visits.

The goal of this study is to learn about how the hormone insulin controls blood sugar in a variety of people. The main question it aims to answer is about how much insulin the body actually needs to maintain a normal blood sugar level. Participants will be asked to come in for a one-day study visit in which they will undergo a "graded insulin suppression test" ("GIST"). The GIST involves intravenous (into the vein) infusions of octreotide, a medication that turns off the body's own production of insulin, as well as replacement of insulin at two different levels (low and high), with or without replacement of glucagon, and glucose (sugar). The study investigators will check blood sugar levels every few minutes during the procedure to determine the effect of the two different insulin levels. This study will evaluate the GIST in both healthy volunteers and those at higher risk for type 2 diabetes.

The goal of this study is to test an adapted treatment for teen insomnia in comparison to a waitlist condition. Cognitive Behavioral Therapy for Insomnia (CBT-I) is an intervention that was developed for adults and is sometimes also used for teens. Teens, parents, and health care providers helped to review and adapt CBT-I to form Teen CBT-I. Teen CBT-I includes most of the same content as CBT-I, with some changes to match teen biology and lifestyles. The main questions this clinical trial aims to answer are: - Does Teen CBT-I improve insomnia symptoms in teens? o Researchers will compare Teen CBT-I to the waitlist control condition to see if insomnia symptoms significantly improve in the treatment group. - Do teens and their parents find Teen CBT-I to be acceptable? o Researchers will examine Teen CBT-I acceptability ratings. Teen CBT-I is hypothesized to improve insomnia symptoms in teens, and teens and parents are hypothesized to find Teen CBT-I to be acceptable. Teen participants will be randomized to one of the two conditions: Teen CBT-I treatment or waitlist control. They will also complete assessments at three timepoints: Baseline (before treatment); post-intervention (after treatment); and follow-up (2 months after treatment). For each assessment, teen participants will: - Fill out questionnaires about their sleep, mood, and other areas - Keep daily sleep logs for one week - Wear an actigraph, a wrist-watch like device that records activity levels to determine sleep-wake patterns, for one week. Parent participants will also be asked to complete questionnaires at each measurement point about their teen's sleep, mood, and other areas. The intervention conditions are: - Teen CBT-I includes 4-6 one-hour individual virtual sessions with a therapist. It includes standard CBT-I content with some small changes to match teen biology and lifestyles. The main parts of this treatment include healthy sleep habits, only using the bed for sleep, keeping a recommended sleep schedule, changing negative thoughts about sleep, and learning ways to relax the mind and body for sleep. - Waitlist-control, in which teens will not receive any treatment for 8 weeks. After the second assessment, they will receive free access to an app-based CBT-I treatment which they can complete on their own.

Individuals with lactase non-persistence (LNP; determined by a functional variant in the LCT gene [rs4988235, GG genotype]) are susceptible to lactose intolerance in adulthood due to deficiency of lactase, the enzyme which digests milk lactose sugars. However, many LNP individuals still drink ≥1 cup of milk daily. Recent analysis in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) found that consumption of 1 serving (cup) of milk/day was associated with ~30% lower risk of type 2 diabetes among LNP individuals, but not among individuals with lactase persistence (LP). This beneficial effect might be partially explained by favorable alterations in gut microbiota and related metabolites associated with higher milk consumption among LNP individuals. Based on these observational study findings, the investigator team proposes to conduct a randomized, controlled trial of lactose-containing vs. lactose-free milk in LNP individuals with pre-diabetes, to comprehensively investigate the effects of milk intake on the gut microbiome and glycemic outcomes.

This study aims to assess a mobile app called MAYA for use in middle-aged and older adults with anxiety or mood disorders. The MAYA app is designed to teach coping skills for anxiety and depression that are drawn from cognitive behavioral therapy. Participants will be asked to use the app for at least two days a week, 20 minutes on each day, for six weeks. Participants will have weekly check-ins as well as longer assessments at the beginning of the study, week 3, week 6 (end of treatment), and week 12 (follow up). During assessments, participants will answer brief questionnaires designed to assess their symptoms and impressions of the app. The main hypotheses of the study are that participants will complete most of the assigned sessions and that they will rate their impressions of the app highly. The secondary hypotheses are that symptoms of depression and anxiety will decrease with use of the MAYA app.

Fibromuscular dysplasia (FMD) is a disease of the arteries that is not due to plaque build-up or inflammation. While some patients with FMD are health, some may experience heart attacks, strokes, aneurysms or blood vessel dissection/tearing which can be life-threatening. It predominantly impacts women and younger patients. As a result of this diagnosis, many patients are counseled to restrict or avoid certain physical activities out of concern for provoking or worsening vascular complications. There are no guidelines or consensus recommendations regarding appropriate physical activity for patients with FMD. The lack of consensus may lead to confusion for patients and may negatively impact their quality of life. This study will conduct a large, national survey of patients with FMD to assess the type of physical activity restrictions and impact on quality of life and emotional well-being.
