This study is for patients that have been diagnosed with relapsed/refractory neuroblastoma. The investigational drug given is eflornithine (DFMO) along with etoposide. DFMO is the investigational drug being used along with etoposide for treatment of neuroblastoma. Participants will undergo a number of standard tests and research-related procedures before being able to enroll in this study. Some risks include but are not limited to: fewer red and white blood cells, diarrhea, abdominal pain, loss of appetite, skin rash, seizure, difficulty swallowing and blurred vision. Participants can expect to be on this study for approximately 2 years. Participants will then be followed for up to 5 years after study completion.

This project is a pilot study to determine if use of the J-Tip Needle-Free Injection System, used to administer local anesthesia, has any effects on the appearance of skin samples when viewed under a microscope compared with skin samples that have been injected with local anesthesia using a needle. If use of the J-Tip device for local anesthesia delivery is shown not to alter the microscopic appearance of skin, anesthesia for skin biopsies in the future may potentially be performed without a needle, allowing for less fear and pain.

There are two classes of drugs for preventing blood clots in patients with atrial fibrillation (AF), an irregular heartbeat, after cardiac surgery: antiplatelet drugs (like aspirin) and anticoagulants (blood thinners). This study aims to determine whether the addition of blood thinners to antiplatelet drugs will improve treatment outcomes in patients who develop AF after coronary artery bypass grafting (CABG) surgery.

In this study, you will be randomized (assigned to a group by chance--like flipping a coin) into one of 2 study groups; the assignment to receive the antiplatelet drug alone or the antiplatelet drug plus a blood thinner.

Before discharge from the hospital, you will undergo an electrocardiogram (ECG), which examines the electrical activity of your heart. At 1 and 2 months after randomization, you will receive a phone call from the study staff. At 3 months after randomization, you will return to the institution where you received your surgery for an in-person visit. At 6 months, you will receive a phone call from the study staff. Your total participation will be about 6 months.

This is an OLE study for subjects completing from one of two double-blind clinical
trials. Subjects must have completed the Week 13 visit from one of these two parent
clinical trials to be eligible for this OLE.

This collaborative study was developed by the Lung Cancer Mutation Consortium (LCMC) and supported by the Thoracic Surgery Oncology Group (TSOG). The purpose of this study is to determine if it is possible to identify genetic changes in the tumors or blood of patients with early-stage lung cancers using both blood-based and tumor-based testing when cancer is suspected or first diagnosed. In this trial, participants will be asked to provide blood samples at three different time points. They will also be asked for permission for tumor tissue to be sent to the researchers. Tumor tissue will be collected if there is a leftover sample from a participant's surgery. These samples will be sent to the researchers to be analyzed for genetic changes. The researchers hope that in the future, genetic changes can help doctors determine what the best treatment is for patients with early-stage lung cancer.

The goal of this study is to develop a biorepository to store pediatric biospecimens from nephrology cohorts for on-going and future research studies. These studies plan to advance the state of science in the hopes to find more information that potentially leads to developing novel diagnostic approaches and identify therapeutic targets to prevent and/or treat pediatric disease involving the kidneys.

The purpose of this study is to demonstrate that the continuous use of negative pressure dressings for up to 14 days has similar benefits and risks to the continuous use for up to 7 days. The 3M study product being used in this study includes the PREVENA Plus Incision Management System with PREVENA Dressings (Peel & Place, Customizable and ARTHRO●FORM). The study product is considered investigational because it has not been approved by the FDA for continuous use for up to 14 days. It is currently approved for use for up to 7 days.

This is a randomized study to test a smartphone app that a pharmacist will use to help kidney transplant patients track their medications, blood pressures, and blood sugars if they have diabetes. The goal of this study is to improve care and outcomes in kidney transplant patients and, in particular, help African American patients have better outcomes after transplant.

This study is for subjects that have been diagnosed with prostate cancer, and their doctor has recommended external beam radiation therapy. The purpose of the study is to evaluate the side effects of a shorter course of radiation called stereotactic ablative body radiotherapy (SABR). The expected duration of the study is up to 28 months including one to four months prior to radiation therapy for treatment preparation, two weeks during radiation therapy, and 24 months after radiation therapy.

This study is for patients with bladder cancer. The study is being done to see if by using one type of chemotherapy instilled in the bladder, Gemcitabine and Docetaxel, instead of the usual BCG therapy can lower the chance of the patient's bladder cancer from growing or spreading.
