Current methods of measuring the response to new treatments for muscular dystrophies involve the examination of small pieces of muscle tissue called biopsies. The investigators are interested in finding less invasive methods that reduce the need for muscle biopsies. The purpose of this research is to learn about the possibility of detecting and measuring the activity and severity of muscular dystrophies by examining a urine sample and a blood sample.

The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke" is defined as either (1) an acute ischemic stroke (AIS, or blood clot in the brain), (2) an intracerebral hemorrhage (ICH, or bleeding in the brain), (3) or an aneurysmal subarachnoid hemorrhage (aSAH, or bleeding around the brain caused by an abnormal bulge in a blood vessel that bursts). The investigators hypothesize that: 1. The size, type and location of the stroke play an important role in recovery of thinking and memory abilities after stroke, and pre-existing indicators of brain health further determine the extent of this recovery. 2. Specific stroke events occurring in individuals with underlying genetic or biological risk factors can cause further declines in brain heath, leading to changes in thinking and memory abilities after stroke. 3. Studying thinking and memory alongside brain imaging and blood samples in patients who have had a stroke allows for earlier identification of declining brain health and development of individualized treatment plans to improve patient outcomes in the future.

Machine perfusion technology is nearing the point of rescuing discarded liver grafts in the hope of proving them to be or improving them to the point of being transplantable. However, there are no validated metrics to determine transplantability after machine perfusion. This study involves collecting biopsies from transplanted livers before and after implantation to correlate metabolite and gene expression with post-transplant function. This data will help develop a viability index for machine perfused livers.

This study aims to evaluate a preoperative fracture analysis tool that uses 3D visualization and biomechanical modeling to assist surgeons in planning screw and plate fixation for complex tibial plateau fractures. By simulating different fixation strategies based on patient-specific CT data, the tool provides insights into construct stability, potentially improving surgical precision and reducing intraoperative uncertainty. The study also investigates the tool's feasibility within current clinical workflows without altering the standard of care.

The study team aims to adapt a psychosocial intervention to reduce psychological distress among the caregiving parents of adolescents and young adults (aged 15-39) who have cancer. First, the study team will adapt an evidence-supported, group-based program for improving psychological resiliency (Stress Management and Resiliency Training - Relaxation Response Resiliency Program; SMART-3RP(E. R. Park et al., 2021)), and iteratively incorporate feedback from parents of AYA with cancer using a mixed-methods approach. Next, the study team will pilot the refined intervention to assess for preliminary indicators of feasibility, acceptability, and potential for efficacy in reducing parental distress.

During breast surgery, sensory nerves are cut which may lead to reduced sensation and pain. Surgical reinnervation techniques have been developed with the aim of improving postoperative sensation by preserving the nerves and connecting them to the nipple and areola. The investigators aim to compare postoperative sensation and patient reported outcomes in patients undergoing reinnervation versus those not undergoing reinnervation to determine if there is a difference. The investigators will investigate this in patients undergoing gender-affirming mastectomy, implant-based breast reconstruction and autologous breast reconstruction. The investigators will use various tools that measure sensation quantitatively.

Non-alcoholic fatty liver disease (NAFLD) is a growing epidemic in the United States. Despite this, the treatment options remain limited. Preclinical and preliminary clinical data suggest that estrogen deficiency plays an important role in the pathology of steatosis, inflammation and fibrosis in non-alcoholic steatohepatitis (NASH), the progressive form of NAFLD. Post-menopausal women are a growing population with particularly high risk of NASH due to their lack of estrogen. This study will examine the effect of estradiol on hepatic fibrosis and fat in post-menopausal women with NASH.

Patients undergoing transcatheter aortic valve replacement (TAVR) often have concomitant coronary artery disease (CAD) which may adversely affect prognosis. There is uncertainty about the benefits and the optimal timing of revascularization for such patients. There is currently clinical equipoise regarding the management of concomitant CAD in patients undergoing TAVR. Some centers perform routine revascularization with percutaneous coronary intervention (PCI) (either before or after TAVR), while others follow an alternative strategy of medical management. The potential benefits and optimal timing of PCI in these patients are unknown. As TAVR expands to lower risk patients, and potentially becomes the preferred therapy for the majority of patients with severe aortic stenosis, the optimal management of concomitant coronary artery disease will be of increasing importance. The COMPLETE TAVR study will determine whether, on a background of guideline-directed medical therapy, a strategy of complete revascularization involving staged PCI using drug eluting stents to treat all suitable coronary artery lesions is superior to a strategy of medical therapy alone in reducing the composite outcome of Cardiovascular Death, new Myocardial Infarction, Ischemia-driven Revascularization or Hospitalization for Unstable Angina or Heart Failure. The study will be a randomized, multicenter, open-label trial with blinded adjudication of outcomes. Patients will be screened and consented for elective transfemoral TAVR and randomized within 96 hours of successful balloon expandable TAVR. Complete Revascularization: Staged PCI using third generation drug eluting stents to treat all suitable coronary artery lesions in vessels that are at least 2.5 mm in diameter and that are amenable to treatment with PCI and have a ≥70% visual angiographic diameter stenosis. Staged PCI can occur any time from 1 to 45 days post successful transfemoral TAVR. Vs. Medical Therapy Alone: No further revascularization of coronary artery lesions. All patients, regardless of randomized treatment allocation, will receive guideline-directed medical therapy consisting of risk factor modification and use of evidence-based therapies. The COMPLETE TAVR study will help address the current lack of evidence in this area. It will likely impact both the global delivery of health care and the management and clinical outcomes of all patients undergoing TAVR with concomitant CAD.

The purpose of this study is to see whether Isatuximab can help improve kidney function of participants with MGRS. Isatuximab is approved by the Food and Drug Administration (FDA) for the treatment of adult patients with multiple myeloma, but it is not approved by the FDA to treat MGRS. This means that the use of isatuximab in this study is considered 'investigational'.
