Primary immune thrombocytopenia (ITP) is a condition where the immune system mistakenly destroys platelets, which are cells that help stop bleeding. This leads to a low number of platelets, making it easier to bruise or bleed. The main aim of this study is to learn whether mezagitamab, when given just under the skin (subcutaneously [SC]), is effective in keeping the platelet count of adults with ITP stable when compared to a placebo. A placebo looks like medicine but doesn't have any active ingredients in it. The participants will be treated with mezagitamab for up to 6 months. During the study, participants will visit their study clinic several times. Participants who complete the TAK-079-3002 study or do not have any response to study treatment by week 16 (according to study criteria) will be given the opportunity to participate in a continuation study to receive open label mezagitamab (if they are eligible and the site is able to open the continuation study).

Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. In previous research atomoxetine and oxybutynin showed promising effect at reducing OSA severity, however they reduced arousal threshold, one of the key traits responsible for OSA. Since oxybutynin was used mainly as a hypnotic, but it is burdened by several anti-cholinergic side effects, DAW2020, a hypnotic which prolonged the total sleep time in a previous trial in OSA patients, could be a better candidate to associate with atomoxetine.

The goal of this clinical trial is to test two new behavioral interventions designed to reduce stress and improve spiritual well-being in stressed adults. The main questions it aims to answer are: 1. Can the program decrease stress and improve spiritual well-being? 2. What brain changes accompany participation in the programs? Participants will: 1. Be randomized to either a live online course that meets for 90 minutes every week for 8-weeks, or to a self-paced program. In the self-paced program, participants will receive materials once a week and can work through them at their own pace. Both programs are designed to decrease stress and improve well-being. 2. Complete questionnaires before and after the course. 3. Complete and interview before and after the course. 4. A subset of people will be randomized to complete an MRI scan of their brain before and after the course. Participants will be randomized to either take the course right away, or be put on a wait-list. Those on the wait-list will undergo the testing at 2 timepoints before they start the program.

The goal of this clinical trial is to learn how three current insomnia therapies (trazodone, daridorexant, cognitive behavioral therapy for insomnia) compare with each other in peri- and post-menopausal women. It will also learn about the safety of the treatments. The main questions it aims to answer are: Which commonly used insomnia therapies are most effective and safe for improving insomnia symptoms in peri- and post-menopausal people? How well do the treatments work for people from different backgrounds, who are at different stages of menopause, and who have different conditions common during menopause (e.g., sleep apnea, mood disturbance, etc.)? What medical problems do participants have when using these treatments? Participants will: Be asked to take trazodone every night, take daridorexant every night, or participate in an online behavioral program for insomnia, for a total of 12 months. Participate in a total of one in-person visit and 7 virtual visits (phone calls) over the 12 months. Wear (and keep) a Fitbit and fill out a daily sleep diary for at least 4 weeks over the 12 months. Fill out online surveys 4 times over the 12 months.

This observational research study is to better understand patients with eosinophilic esophagitis (EoE) who have recently been prescribed DUPIXENT® (dupilumab). The purpose of this research study is to look at how DUPIXENT is used in normal care of patients with EoE. Possible benefits to others include a better understanding of EoE and helping to inform research and clinical trial design leading to treatment decisions in this patient population going forward. Patient questionnaires will measure the following: - How EoE makes one feel - EoE signs and/or symptoms, eg, how difficult it is to swallow - How EoE affects quality-of-life - How EoE impacts aspects of daily life - How EoE symptoms have changed throughout the study

The goal of this observational study is to research the impact of molecular signals from the heart, liver and fat tissue on cardiovascular disease risk, and the presentation of Type II Diabetes and diseases that affect the heart, blood vessels and metabolism (Cardiometabolic Disease). Specifically, the focus is on the content and function of Extracellular Vesicles (EVs), small sacs released from a cell's surface that contain important molecular cargo. The main questions it aims to answer are: 1. What molecular cargo do adipose-tissue EVs carry? 2. How do these cargo impact cardiac and hepatic function? 3. Are changes in EV content related to cardiac function and adiposity with weight loss? Tissue samples from fat tissue and blood samples will be collected from patients receiving bariatric weight loss surgery.
