We are looking for patients with kidney disease and healthy controls (no kidney disease) to provide blood samples, fill out surveys, and provide health related information to help investigators learn more about how to better diagnose and treat kidney disease. The information you provide will go into a "library" of data for doctors and researchers across the world to use for research projects. If you are a kidney patient, we are able to use your information to find out if you are eligible for treatment studies/other studies in the future.

The purpose of this study is to learn more about three kidney diseases called nephrotic syndrome: Focal Segmental Glomerulosclerosis (FSGS), Minimal Change Disease (MCD), and Membranous Nephropathy (MN). By collecting health information and laboratory samples from individuals who have these diseases and by making this information available to researchers, we hope to gain new knowledge about these diseases and to find better treatments for them.

Study to evaluate the safety and effectiveness of the InnAVasc Arteriovenous Graft (IG) for hemodialysis (HD) access in patients with end-stage renal disease (ESRD).

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

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 understand how body fat and skeletal muscle in your body impacts your heart, kidney, and metabolic health. This research may help to better diagnose and treat patients and prevent progression of cardiovascular-kidney-metabolic diseases.

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.

This research is studying the JuxtaFlow® Renal Assist Device (JuxtaFlow® RAD), to determine whether it enhances kidney function in patients with kidney function problems who are having a heart operation that requires a heart-lung machine. This device is investigational, which means it is not approved by the (Food and Drug Administration) FDA. However, the FDA or regulatory body has approved the clinical use of this device in this research study.

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.

A multicenter prospective trial with randomized and observational cohorts assessing patient-reported outcomes and unplanned healthcare utilization following ureteroscopic treatment of renal and ureteral stones, with stent omission versus placement of a ureteral stent.
