800 adult first time kidney transplant recipients will be enrolled in the Observational Study and followed to evaluate their Human Leukocyte Antigen (HLA)-DR/DQ molecular mismatch (mMM) score as a risk-stratifying prognostic biomarker. Six months after transplant the study will identify those who meet the eligibility criteria for the Nested Randomized Control Trial (RCT). 300 eligible subjects will be randomized 2:1 to abatacept or Standard of care (SOC) in the randomization and followed for 18 months monitoring for safety and improvement in renal function, neurocognitive function, and a life participation patient reported outcome measure (PROM). The primary objective of the Observational Study is to test the validity of the HLA-DR/DQ mMM score as a prognostic biomarker for stratification of post-transplant alloimmune risk. Whereas the objective of the Nested RCT is to test whether a superior outcome in kidney function (primary endpoint), as well as secondary endpoints (neurocognitive function, and life participation PROM), will be achieved in patients who are transitioned from Tacrolimus (TAC) to abatacept, while maintaining efficacy (freedom from biopsy proven acute rejection).

This phase III trial compares minimally invasive surgery (MIS) to laparotomy in treating patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer who are receiving chemotherapy before and after surgery (neoadjuvant chemotherapy). MIS is a surgical procedure that uses small incision(s) and is intended to produce minimal blood loss and pain for the patient. Laparotomy is a surgical procedure which allows the doctors to remove some or all of the tumor and check if the disease has spread to other organs in the body. MIS may work the same or better than standard laparotomy after chemotherapy in prolonging the return of the disease and/or improving quality of life after surgery.

In this research study we want to learn more about the effects of non-invasive brain stimulation on memory and brain-network function in cognitively unimpaired older adults and in patients with amnestic mild cognitive impairment (aMCI). This study will use a form of non-invasive brain stimulation called repetitive Transcranial Magnetic Stimulation (rTMS). rTMS will slightly alter activity in an area of your brain that controls memory. Changes resulting from this stimulation will be measured with behavioral tests of memory and general cognition, as well as by taking images of your brain with Magnetic Resonance Imaging (MRI). Participants will come in for one baseline visit followed by 10 days of daily rTMS study visits (Monday through Friday) and an evaluation visit. Then, there will be a 2-week break. After this break, they will return for another baseline visit, an additional 10 days of rTMS, and a final evaluation visit.

This study is researching an experimental CAR T cell therapy called 27T51, referred to as study drug. The study drug is a MUC16 targeting immune cell therapy focused on adult female participants with recurrent or difficult to treat epithelial ovarian, primary peritoneal or fallopian tube cancer. This study has two (2) major parts: Phase 1a Dose Escalation and Phase 1b Dose Expansion. The aim of the dose escalation part will be to test the safety of 27T51 in a small number of participants to find the highest dose given to humans without unacceptable side effects. The aim of the dose expansion part will be to test 27T51 at the established dose level(s) from the dose escalation part and may include other medications given in combination with 27T51. Information collected from this study will help researchers understand more fully whether this immune cell therapy, also known as CAR T cell therapy, can be safely used to treat solid tumors such as ovarian cancer.

A prospective multicenter study enrolling high surgical risk patients with severe mitral annular calcification (MAC) and symptomatic mitral valve dysfunction (severe stenosis, ≥ moderate to severe regurgitation, or mixed ≥ moderate stenosis and ≥ regurgitation). There are 2 Arms in this study: 1) "Transseptal (TS) Valve-in-MAC" (ViMAC) Arm, and 2) Natural History of Disease Registry (NHDR) for patients treated with medical treatment only (which includes patients who meet inclusion criteria but can't be treated with transeptal ViMAC due to the presence of anatomical exclusion criteria or other exclusion criteria) and have not had other procedures that may impact outcomes (i.e., alcohol septal ablation or radiofrequency ablation). The study also includes a Registry of Permanently Unassigned" for subjects who undergo preemptive septal ablation procedures (alcohol or radiofrequency) in anticipation of continuing onto ViMAC arm, but are not accepted in the ViMAC Study arm or the patient chooses not to undergo ViMAC procedure.

The primary objectives of this study are twofold: 1) to detect and determine the level of symptoms, functional disability, and changes in quality of life that breast cancer patients experience from changes in their arms during and after treatment for breast cancer by collecting patient reported outcome measures, objective measurements, and clinical information in a prospectively maintained database and 2) to improve breast cancer-related lymphedema outcomes by early detection using objective measurements and symptoms assessments and assess these outcomes by maintaining the data in a database in order to contribute to the literature. The secondary aim of this study is to assess extracellular fluid content in the upper extremity, breast, and/or trunk of patients treated for breast cancer before, during, and after treatment in order to better understand the role of bioimpedance spectroscopy in lymphedema screening.

Many people living with metastatic breast cancer face challenging symptoms and frequent medical visits. At the same time, conversations about personal goals, values, and preferences for care may not always happen as early or as often as patients and families would like. This multi-site study will test the effectiveness of a five-session palliative care program, designed specifically for people with metastatic breast cancer and their caregivers, to strengthen communication with clinicians about what matters most in their care. The study aims to inform how palliative care services can be delivered in a more timely, personalized, and scalable way for people living with advanced cancers who have long disease trajectories, such as metastatic breast cancer.

The goal of this pilot clinical trial is to test efgartigimod alfa against placebo in adults with first-time optic neuritis (optic nerve inflammation). The main questions it aims to answer are: - Is it feasible to use efgartigimod alfa for optic neuritis? - Is it feasible to run a larger trial testing efgartigimod alfa in optic neuritis? - Does efgartigimod alfa work better than placebo in improving how quickly and how much vision returns? Participants will: - have their vision and blood tested - be asked questions about their vision - will receive standard of care treatment with steroids regardless of whether they are receiving efgartigimod alfa or not - will have periodic visits over 6 months

This is a clinical trial to evaluate the use of peritumoral injection of near-infrared dye indocyanine green to identify lung lesions and sentinel lymph nodes. The primary purpose is to determine if the use of ICG injected via navigational bronchoscopy, CT-guided or transthoracic allows us to identify the first lymph node that drains from the tumor, and thus would be the most likely site for metastatic disease, and remove it for analysis to improve the ability to detect tumor in this node and to remove this additional site that potentially contains tumor cells. Using this intraoperative imaging technique, we aim to improve the identification of lung nodules for resection and the intraoperative identification of sentinel lymph nodes in the event that a lymphadenectomy is performed.
