Nonalcoholic fatty liver disease (NAFLD) is a spectrum of liver conditions associated with fat accumulation that ranges from benign, non-progressive liver fat accumulation to severe liver injury, cirrhosis, and liver failure. The spectrum of NAFLD encompasses simple nonalcoholic steatosis (nonalcoholic fatty liver [NAFL]) and nonalcoholic steatohepatitis (NASH) in which there is evidence of hepatocellular injury and/or fibrosis. NAFLD is the most common liver disease in adults and the second leading cause for liver transplantation in the U.S. The natural history of NAFLD in the general population has been well described. The NASH Clinical Research Network (NASH CRN) was established by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) in 2002 to further the understanding of the diagnosis, mechanisms, progression and therapies of NASH. This effort has resulted in numerous seminal studies in the field. However, NASH CRN studies have systematically excluded persons living with HIV (PLWH) , as NAFLD in PLWH was thought to be different from that in the general population due to HIV infection, antiretroviral therapy (ART), concomitant medications and co-infections. This resulted in major knowledge gaps regarding NAFLD in the setting of HIV infection. Thus, the natural history of NAFLD in PLWH is largely unknown. The goal of this ancillary study of NAFLD and NASH in Adults with HIV (HIV NASH CRN), is to conduct a prospective, observational, multicenter study of NAFLD in PLWH (HIV-associated NAFLD).

Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is an emerging field in minimally invasive surgery. International consensus-based statement was recently published to help guide the basis for adopting vNOTES into clinical practice, including regarding patient selection. It was agreed that women with potential adhesions are not appropriate candidates for vNOTES approach including women with suspected adhesions due to history of severe pelvic inflammatory disease (PID) or endometriosis. However, as some pelvic infections might be asymptomatic, pre-operation imaging might be beneficial to complete improved selection of patients. Moreover, women with previous severe PID or endometriosis might still have favorable pelvic to perform the vNOTES approach. Therefore, we aim to compare pre-operation ultrasound evaluation to operative characteristics and outcomes in women undergoing VNOTES approach surgery.

ASCEND researchers are partnering with families of children who receive extracorporeal membrane oxygenation (ECMO) after a sudden failure of breathing named pediatric acute respiratory distress syndrome (PARDS). ECMO is a life support technology that uses an artificial lung outside of the body to do the lung's work. ASCEND has two objectives. The first objective is to learn more about children's abilities and quality of life among ECMO-supported children in the year after they leave the pediatric intensive care unit. The second objective is to compare short and long-term patient outcomes in two groups of children: one group managed with a mechanical ventilation protocol that reserves the use of extracorporeal membrane oxygenation (ECMO) until protocol failure to another group supported on ECMO per usual care.

This study is focused on males who have Hemophilia B and who need regular preventive treatment with factor IX protein (FIX) replacement therapy to prevent and also to control their bleeding events. The aim of the study is to gather at least 6 months of information on bleeding events for each individual participant while they continue to use their usual FIX replacement therapy. There is no experimental treatment being tested in this study. The study is informational, and part of a larger program to understand and treat Hemophilia B with a potential experimental new therapy in the future. There is no obligation to agree to taking part in this future study. The study is looking to answer several other research questions to help understand each participant's individual disease characteristics, including: - How often to use FIX replacement therapy, both on a regular basis (prophylaxis) and as needed to treat bleeding events - Measurement of FIX activity (factor IX is a clotting factor) by different laboratories using different types of tests in Hemophilia B participants - Possible complications from the FIX replacement therapy the patient receives (usual standard of care will continue to be used) - How quality of life is affected by Hemophilia B - How joint health is affected by Hemophilia B - How often the participant visits the emergency room, urgent care center, physician's office, hospital, or has a telemedicine visit as a result of bleeding events - Whether the body makes antibodies (a protein produced by the body's immune system) against the FIX replacement therapy you receive, which could make the drug less effective or could lead to side effects

Prospective, controlled, multicenter clinical investigation with four trial cohorts: Randomized, Non-repairable, Severe Mitral Annular Calcification (MAC) and Severe Mitral Annular Calcification Continued Access Protocol (MAC CAP). Subjects in the Randomized cohort will be randomized in a 1:1 ratio to the trial device or to the MitraClip system. Subjects in the Non-repairable, Severe MAC, and Severe MAC CAP cohorts will receive the trial device. The objective of the Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Transcatheter Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation (SUMMIT) is to evaluate the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System for the treatment of patients with symptomatic, moderate-to-severe or severe mitral regurgitation or for patients with symptomatic mitral valve disease due to severe mitral annular calcification. This randomized controlled trial will provide the opportunity to evaluate the safety and clinical benefits of the Tendyne Transcatheter Mitral Valve System compared to the MitraClip System in patients with symptomatic, moderate-to-severe or severe mitral regurgitation, within approved MitraClip indications. In addition, the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System will be evaluated in patients with severe mitral annular calcification who are at prohibitive risk for mitral valve surgery. Patients who are not suitable for mitral valve surgery for reasons other than severe mitral annular calcification and are also not suitable for transcatheter repair with MitraClip, will be enrolled in the Non-repairable cohort. Subjects will be seen at screening, pre- and post-procedure, discharge, 30 days, 3 months, 6 months, and annually through 5 years.

Alzheimer's disease and related dementias lead to marked declines in daily functioning, independence, and quality of life. One of the earliest cognitive changes in these conditions is impairment in prospective memory, or the ability to remember future intentions such as taking medications at a given time. Prior intervention studies that targeted prospective memory used mnemonic strategies or cognitive training, but these approaches resulted in modest gains in clinical populations. By contrast, a Stage I pilot trial indicated that smartphone-based memory aids (reminder apps) can be accepted and used by persons with mild cognitive impairment and mild dementia to improve both subjective and objective prospective memory performance. The investigators will now test for efficacy, durability, and generalizability of benefits across diverse samples in a Stage II randomized controlled trial. Some 200 participants with mild cognitive impairment or mild dementia will be recruited, half of whom will be from digitally-disadvantaged backgrounds (low socioeconomic status, rural, or historically underrepresented groups). Participants will complete baseline assessments and then be randomly assigned to a smartphone reminder app intervention or an active control condition that uses a paper- based memory support system. Across a 4-week intervention period, participants will complete patient-selected and experimenter-assigned prospective memory assessments and receive booster training sessions to promote self-efficacy with the intervention/control system. Durability of effects will be assessed at 3-month and 6-month follow-up sessions. As a secondary aim, study partners will be simultaneously enrolled to collect informant ratings, track how much study partners assist the participants, and determine whether improving prospective memory in patients improves quality of life in study partners (e.g., by reducing the double to-do list burden of remembering for themselves and for care recipients). As a third aim, the investigators will identify barriers and facilitators to smartphone interventions in digitally-disadvantaged individuals who have historically been underrepresented in technology and dementia research.
