un Sung A portable urea sensor for use in fast flow conditions was fabricated using porous polytetrafluoroethylene (PTFE) membranes coated with amine-functionalized parylene, parylene-A, by vapor deposition. The urea-hydrolyzing enzyme urease was immobilized on the parylene-A-coated PTFE membranes using glutaraldehyde. The urease-immobilized membranes were assembled in a polydimethylsiloxane (PDMS) fluidic chamber, and a screen-printed carbon three-electrode system was used for electrochemical measurements. The success of urease immobilization was confirmed using scanning electron microscopy, and fourier-transform i...

Abstract BACKGROUND: The impact of institutional case volume to graft failure rate after adult kidney transplantation is relatively unclear compared to other solid organ transplantations. METHODS: A retrospective cohort study of 13,872 adult kidney transplantations in Korea was performed. Institutions were divided into low- ( 60 cases/year) volume centers depending on the annual case volume. One-year graft failure rate was defined as the proportion of patients who required dialysis or re-transplantation at one year after transplantation. Postoperative in-hospital mortality and long-term graft survival were al...

Objective: To explore putative different impacts of delayed graft function (DGF) on long-term graft survival in kidneys donated after brain death (DBD) and circulatory death (DCD). Background: Despite a 3-fold higher incidence of DGF in DCD grafts, large studies show equivalent long-term graft survival for DBD and DCD grafts. This observation implies a differential impact of DGF on DBD and DCD graft survival. The contrasting impact is remarkable and yet unexplained. Methods: The impact of DGF on DBD and DCD graft survival was evaluated in 6635 kidney transplants performed in The Netherlands. DGF severity and functi...

Conclusions: Our data demonstrate that RTCA is feasible and clinically meaningful. The RTCA score predicts DGF and is a valid option to be applied in renal transplantation.

We describe the clinicopathologic features of BKPyV-associated urologic carcinomas in a single-institution cohort. RESULTS: Among 4,772 kidney recipients during 1994 to 2014, 26 (0.5%) and 26 (0.5%) developed posttransplantation urothelial carcinomas (UCs) and renal cell carcinomas (RCCs), respectively, as of 2017. Six (27%) UCs but none of the RCCs expressed large T antigen (TAg). TAg-expressing UCs were high grade with p16 and p53 overexpression (P

Conclusions: Recipients of experimental HCV D+/R- transplants generally seemed to recognize the risks and benefits of these novel transplants and did not regret participating. Such salutary reported experiences are important in assessing the appropriateness of further research into the feasibility of HCV D+/R- transplants. PMID: 31618112 [PubMed - as supplied by publisher]

Increased tuberculosis (TB) disease risk has consistently been observed among solid organ transplant recipients [1, 2]. This may result from post-transplant immunosuppressive therapy, although underlying disease processes leading to transplant (including chronic kidney disease) are also associated with increased risk [3]. TB among transplant recipients is associated with increased risk of drug toxicity, drug–drug interactions, graft failure and mortality [4], and can lead to transmission to other vulnerable hospitalised patients. Consequently, global guidelines recommend systematic screening of patients undergoing so...
