This is a research study among women living with HIV about their choices in how they feed their infants and the different factors that contribute to those decisions, as well as how those decisions change after giving birth and as their baby grows. This study includes surveys at 2 different time points- once while still pregnant, once approximately 4-6 weeks postpartum. We hope to gain understanding on womens choices about breastfeeding while living with HIV.

The purpose of this research study is to examine the effect of a brain stimulation training to improve the function of brain-spinal cord- muscle connections.Because brain-to-muscle pathways are very important in our movement control, restoring function of these pathways may improve movement problems after injuries. Spinal cord injury causes damage to the brain-to-muscle connection. However, when the injury is "incomplete", there is a possibility that some of the brain-to-muscle pathways are still connected and may be trained to improve movement function. For examining brain-to-muscle pathways, we use a transcranial magnetic stimulator. We hope that the results of this research study will help us develop new treatments for people who have movement disabilities. This study will require about 42 visits over the first 14 weeks, and another 6 visits over an additional 3 months. Each visit will take about 1 ½ hours.

The purpose of this study is to see how well the combination of home-based transcranial direct current stimulation (tDCS) and prolonged exposure (PE) works in treating people with chronic pain (e.g., pain related to fibromyalgia, lower back pain, arthritis) and posttraumatic stress disorder (PTSD).

Participants must be a Veteran or Active-Duty service member with a diagnosis of PTSD and chronic musculoskeletal pain. Participants will receive 10 sessions of PE over 2 weeks (called Massed PE) and 10 sessions of tDCS.

This registry is enrolling subjects who are indicated for renal denervation to treat high blood pressure that has remained high despite treatment. Renal denervation is a procedure where a catheter (a thin, flexible plastic tube with four electrodes near the end) is placed inside the blood vessels that go to the kidneys. Heat is delivered through the electrodes to disable the nerve activity and lower the blood pressure.

Participation in this registry will last about 1-3 years and include 3-6 visits depending on how often your doctor typically conducts follow up visits. Data will be collected including medical history, medications, blood pressure readings, labs, from the procedure and from any complications if applicable. There is a risk of loss of confidentiality and there may be risks that are not known. There may be no direct benefit but the information learned may help others in the future.

The purpose of this study is to find out if adding a drug called ribociclib to the usual hormone therapy drugs can lower the chance of your breast cancer coming back again. This study is for patients with locoregional, recrrent, resected hormonone receptor positive HER2 negative breast cancer. Endocrine therapy has already been approved by the FDA for your type of cancer. Ribociclib has already been approved by the FDA for your type of cancer that has not been removed by surgery or has spread to other parts of the body.

Receiving ribociclib with endocrine therapy is still being studied and to yet approved by the FDA. Ribociclib is taken as a pill and endocrine therapy is taken as an injection. Participants will receive ribociclib with endocrine therapy for up to 3 years and can receive endocrine therapy alone for an additional two years after stopping ribociclib. Participants can remain on the study for up to 5 years.

This study is enrolling participants with calcific aortic valve stenosis (CAVS) which is a heart valve disease. Blood pumped out of the heart goes through the aortic valve, and in CAVS, calcium builds up causing the valve to thicken over time so it is not able to open as much or as easily and over time this restricts blood flow. This study involves an investigational medication called ataciguat which is being studied to see how well it can slow the progression of CAVS. Investigational means it has not been approved for commercial use by the Food and Drug Administration (FDA). Ataciguat is taken by mouth daily.

Participation in this study will last about 3 years and include about 14 visits. Study procedures include collection of medical data, physical exams, electrocardiogram (ECG - a recording of your heart's electrical activity), bloodwork, echocardiogram (ultrasound test of the heart), CT scan, questionnaires and home monitoring of your blood pressure and heart rhythm.

Risks related to ataciguat include headache, nausea, abdominal pain, diarrhea and dizziness. Study procedure risks include radiation risks, risks of drawing blood and loss of confidentiality.

This study is for patients that have been diagnosed with prostate cancer. This study will compare metastasis-free survival, determined using conventional imaging, between men with high-risk prostate cancer randomized to ultrahypofractionation (stereotactic body radiation therapy [SBRT]) to those randomized to moderate hypofractionation and conventional fractionation. Participants can expect to remain in the study for 11 years and 10 months.

This study is for subjects that have been diagnosed with prostate cancer. Subjects can expect to remain in the study for up to 39 months or longer. There will be a total of 16 enrolled locally. The study is set to enroll subjects for 39 months.

Patients suspected of having compromised heart function often require invasive right heart catheterization for diagnosis and management. This study is testing the Cardiac Performance System (CPS), a non-invasive device that uses sensors and electrocardiogram (ECG) electrodes to measure heart function. The purpose of this study is to determine if the CPS provides pulmonary pressure assessment similar to that obtained through right heart catherization.

The study is researching an experimental drug called REGN7544. The study is focused on adult patients (18 to 85 years old) hospitalized due to a serious infection (called "sepsis" in this form) and receiving standard-of-care medications for low blood pressure (called "vasopressors" in this form) due to sepsis. The aim of the study is to see if REGN7544 is safe, tolerable and effective when compared to placebo, by observing the effects on blood pressure and the total amount of vasopressor dose received. The general procedures include collection of information from medical records, some additional testing, such as electrocardiogram, collection of blood, and having blood pressure and heart rate measured .There will also be a screening visit, two telephone visits, and one additional in-person visit. It is expected that taking part in this research will last about 13 weeks (3 months).
