HIV-infected individuals treated with antiretroviral medications are living longer, but have an increased risk of heart disease when compared to non-HIV-infected individuals. A hormone called aldosterone, which regulates blood pressure and sodium balance, is elevated in the HIV population in association with with increased belly fat and altered glucose metabolism. Elevations in aldosterone hormone may also be associated with abnormal blood flow, inflammation, and coronary plaque in the heart. This study is being conducted to evaluate whether therapies to reduce the actions of aldosterone may decrease the burden and progression of heart disease in the HIV population.

This study is being conducted to determine if losartan, an angiotensin receptor blocker (ARB), is safe and effective in the treatment of posttraumatic stress disorder (PTSD) symptoms. The study is also intended to determine if certain genetic markers are useful in predicting PTSD symptom reduction with losartan. Approximately 160 subjects with chronic PTSD ages 18-65 will participate in this study across five sites. Subjects will be assigned by chance to take either flexibly dosed losartan (up to a maximum dosage of 100 mg) or placebo (which resembles the study drug but has no active ingredients), once a day for 10 weeks. Furthermore, it is hypothesized that CC homozygotes for rs4311 SNP in the ACE gene will have a superior response to losartan on PTSD symptoms compared to T carriers.

The purpose of the Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation (COAPT) Trial is to confirm the safety and effectiveness of the MitraClip System for the treatment of moderate-to-severe or severe functional mitral regurgitation (FMR) in Symptomatic Heart Failure Subjects who are treated per standard of care and who have been determined by the site's local heart team as not appropriate for mitral valve surgery. This randomized controlled trial will provide the opportunity to strengthen or add labeling claims regarding safety and clinical benefits of the MitraClip System for symptomatic heart failure patients with moderate-to-severe or severe functional mitral regurgitation. Approximately 610 subjects will be randomized at up to 100 investigational sites with approximately 305 subjects targeted to receive the study device. COAPT study completed recruiting subjects in June 2017. As part of the COAPT trial, a subset of patients will be registered in the cardiopulmonary exercise (CPX) sub-study. The objective of this sub-study is to evaluate the exercise responses in a sub-cohort of COAPT subjects who receive MitraClip device (Device group) compared to the Control group who do not receive MitraClip device. (Note: the CPX Sub-study subjects will contribute to the analyses of the COAPT primary and secondary endpoints) As an extension of the COAPT RCT trial, COAPT CAS study will be conducted after COAPT enrollment is complete under the same investigational device exemption (IDE(G120024)). The objective of this study is to evaluate the MitraClip® NT System for the treatment of clinically significant functional mitral regurgitation (FMR) in symptomatic heart failure subjects who are treated per standard of care and who have been determined by the site's local heart team as not appropriate for mitral valve surgery. The anticipated study Primary Completion date is July 2018 and the Study Completion Date is July 2024. COAPT CAS is presently recruiting subjects.

Background: - Without an explanation for severe and sometimes life-threatening symptoms, patients and their families are left in a state of unknown. The NIH helped create a network of medical research centers, called the Undiagnosed Diseases Network (UDN), to provide care and answers for these individuals. Objectives: - To improve diagnosis and care for people with undiagnosed diseases. Eligibility: - People with undiagnosed diseases, and their relatives. Design: - Participants will travel to one of the UDN medical centers for a 5-day clinical and research visit. - As part of the visit, UDN healthcare providers may ask participants to have: - Clinically indicated tests and procedures performed including: - A physical exam - Blood and urine tests - A review of health and family history - X-rays and body scans - Surveys - Photographs of the face and body - A special diet to see if the body can handle the food without having a reaction, like vomiting - Video or voice recordings - Other tests and procedures to help reach a diagnosis - Research tests and procedures performed including: - A skin biopsy. For this, a small piece of skin will be taken. - Surveys - Other tests and procedures for research that may not be related to a diagnosis or treatment. - Most participants will be asked to give samples for genetic testing. - Participants may be contacted after their visit to discuss test results. They may also be contacted in the future for interviews and surveys. - Relatives of participants may be asked to give samples for genetic testing. They may be asked to have parts of their visit recorded and to have additional tests. They may also be contacted in the future for interviews and surveys. - Clinical and research information collected will be stored in a database. - Information and samples collected will be shared with others for research purposes.

Previous research shows that individuals with Body Dysmorphic Disorder (BDD) misinterpret ambiguous social information in a negative and threatening manner. These erroneous threat appraisals are thought to maintain disorder symptomatology and psychosocial impairment by reinforcing individuals' distorted self-image and ideas of social undesirability. Thus, maladaptive interpretation biases represent an important treatment target for this population; however, existing bias assessments and modification protocols are limited by the hypothetical and distal nature of scenarios and do not capture momentary experiential threat processes. The proposed study seeks to test virtual reality (VR) technology as a novel, in vivo means of eliciting, identifying, and measuring threat interpretation biases in a clinical sample to better understand the fear/threat structure activated during social interactions in BDD. Findings have the potential to enhance our understanding of disorder maintenance and identify more nuanced treatment targets. This study represents a critical first step in the long-term goal of harnessing VR gaming technology to supercharge existing treatment approaches for this debilitating illness.
