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.
