The purpose of this research study is to interview patients with fatty liver disease who are planning to have liver surgery. Our goal is to understand patients' health beliefs with fatty liver disease and what weight loss behaviors they would be willing to follow prior to surgery. You are being asked to be in the study because you are a patient with fatty liver disease planning to have liver surgery.

The purpose of this study is to gauge interest in a peer support program to help individuals with chronic kidney disease who are pregnant or are contemplating pregnancy navigate decision-making and care management. This survey will help us understand patients' desires for such a program and ways it can be implemented to best serve their needs and preferences.

We want to learn why and how some people on dialysis form blood clots in the dialysis machine or in their fistula. Most patients on dialysis receive a blood thinner called heparin to prevent these clots, but heparin can sometimes cause bleeding. We would like to know if safer medications could work in preventing these clots. This study is only about learning more information from blood samples and does not involve treatment.

The purpose of this research study is to monitor how well patients with fatty liver disease can follow clinician-recommended diet and exercise before their liver surgery. Our goal is to understand patient adherence to weight-related goals, weight loss, physical activity, and improved liver health. You are being asked to be in the study because you are a patient with fatty liver disease planning to have liver surgery.

To create a biorepository for future research studies to better improve patient treatment in care for patients with liver cancer and liver diseases

To compare disease-free survival (DFS) as assessed by the investigator for high-risk renal cell carcinoma patients treated with adjuvant pembrolizumab and tivozanib versus those receiving pembrolizumab alone.

Belatacept is a drug that helps kidney transplant recipients by preventing the body from rejecting the new organ. We want to compare how well belatacept works compared to the commonly used drug tacrolimus. To do this, we plan to study people who got kidney transplants in the United States from 2011 to 2020. By using two large databases, the United States Renal Data System, and the Scientific Registry of Transplant Recipients, we aim to understand how belatacept is used in real life. We are also interested in comparing how effective and safe is belatacept compared with tacrolimus after one year of administration. We will look at outcomes like how long the transplanted kidney will work, how long will the kidney transplant recipients live, how well your kidneys will work, the risk of organ rejection, and certain side effects to happen after transplant like blood cancer.

This study will compare 3 different ways to educate patients with advanced chronic kidney disease about hemodialysis vascular access.

Liver injury due to prescription and non-prescription medication is medical, scientific, and public health problem of increasing frequency and importance in United States. Drug-induced liver injury (DILI) is the most common reason the Food and Drug Administration (FDA) would choose not to approve a new drug or withdraw a drug from the market. However, drug-induced liver injuries are often under-reported and difficult to detect/diagnose. This study seeks to learn more about these drug-induced liver injuries and develop better ways to detect, define, and study drug-induced liver injuries. The study will be looking at new cases of drug-induced liver injury, as well as gathering data on previous drug-induced liver injury (up to January 1, 1994).

About two in five people who are undergoing a kidney biopsy have diabetes. Diabetes is a common finding in people with kidney disease, but little is known about the specific ways in which diabetes affects kidney function. The purpose of this study is to gather two groups of patients with diabetes who undergo a kidney biopsy in order to create a source of information with genetic, blood, and urine samples available, by which researchers can study how diabetes affects kidney function.
