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.

We are collecting data on children living with chronic kidney disease, including children on dialysis or with a kidney transplant, to learn more about what happens over time. The data collected will be used for research projects.

The research aims to improve how we check for Hepatitis C Virus (HCV) in different healthcare settings, making it easier for people to get tested. We want to see how accurately this test can detect HCV infection in people who might have symptoms or are at risk. We are using a type of blood sample called "EDTA capillary whole blood," which is a small amount of blood collected in a tiny tube with a special substance to prevent it from clotting. This study helps us understand if the Xpert HCV test can be reliable in practical situations where anyone can use it. The goal is to make sure this test is good at finding Hepatitis C infections, especially in places where not many healthcare professionals are available.

Current dialysis vascular access patient education materials can be overwhelming, not written in plain language, and not have enough realistic information about the steps involved in getting a dialysis vascular access before starting hemodialysis. This study is being done to create and test a dialysis vascular access educational video for patients. Participants would take part in a one-time interview about their thoughts on dialysis vascular access education and their ideas for a vascular access video.

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.

The purpose of this IRB approved Humanitarian Use of a device is to allow patients to be treated with LDL-Apheresis, using the LIPOSORBER® LA-15 system. This device is approved for adult and pediatric patients with Focal Segmental Glomeruloslerosis as a Humanitarian Use Device. Its effectiveness has not been demonstrated.

The rationale for this study is to determine if there is a difference in symptoms or complications among patients undergoing uncomplicated ureteroscopy for stone removal with shorter indwelling stent duration. Curently there are only a few small studies exploring the optimal duration of stent placement after stent placement and no multicenter randomized control trials.

We are surveying individuals with sickle cell disease (SCD) and/or parents of a child with SCD to get a sense of the types of treatment they would choose based on the harms and benefits of those treatment options. The proposed study will be designed to meet the following objectives: 1) Elicit individual respondent's maximum acceptable risk (MAR) for treatment benefits 2) Elicit individual respondent's minimum 3) Characterize heterogeneity in MARs and MABs among respondents

To determine in a randomized manner whether the addition of levocarnitine prophylaxis to asparaginase-containing regimens will decrease the incidence of conjugated hyperbilirubinemia (>3 mg/dL) during ALL induction therapy in adolescents and young adults (AYAs, age 15-39 years).

To test the effect of automated RBC exchange transfusion and standard of care compared with standard of care on the number of episodes of clinical worsening of sickle cell disease (SCD)requiring acute health care encounters (non-elective infusion center/ER/Hospital visits) or resulting in death over 12 months in high risk adult SCD patients.
