ABSTRACT Background Methods Results Conclusion Adenovirus (ADV) infection can lead to significant morbidity and mortality in immunocompromised patients, particularly in those with hematopoietic stem cells or solid organ transplants. The incidence of ADV infection in kidney transplant (KT) is not well‐defined as ADV is often asymptomatic and not routinely checked.This retrospective case‐series study included KT and simultaneous pancreas‐KT (SPKT) recipients from January 1, 2008, to January 31, 2024, across three Mayo Clinic sites (Arizona, Florida, and Minnesota) with symptomatic adenovirus polymerase chain reaction cases. The primary outcomes were allograft function at various intervals post‐ADV infection, allograft, and patient survival.We report one of the largest multi‐site case series regarding outcomes of ADV in KT with 17 patients. The median time to ADV infection was 30 weeks (5–74). Five patients (29%) developed disseminated infection. Nine patients (53%) of the entire cohort experienced graft loss within a median of 35 (4–168) weeks, with four (44%) of graft loss attributed to ADV. Nine patients (53%) developed rejections post‐ADV infection with a median of 4 (2–8) weeks after resolution. One patient died from acute hypoxic respiratory failure from ADV infection.ADV should be considered in KT/SPKT patients with renal dysfunction, hematuria, and with or without fever. Despite the low mortality rate, there is a significant risk of graft loss and rejection after ADV infection. It is crucial to screen for ADV and develop intervention strategies for treatment. Further multicenter studies are needed to better define, stage, and manage ADV infection. [ABSTRACT FROM AUTHOR]

Hydrogen production via electrocatalytic water splitting has attracted significant research attention in recent years as it is a clean, sustainable, and renewable energy source. Transition metal phosphides, especially nickel phosphides and transition metal oxides, exhibit high catalytic activity for hydrogen evolution. To overcome current limitations such as high overpotential and instability of catalysts, we developed ZnO-doped highly porous activated charcoal polyaniline-incorporated NiP coatings as electrocatalysts for HER using a simple electroless coating method. The developed catalyst (AC/PANI-ZnO-NiP) exhibits low overpotential (97 mV) at 10 mA cm−2, low Tafel slope (81 mV dec−1), and high Cdl (280.9 μF). The exceptional electrochemical performance is due to the presence of a protonated NH group in PANI and increased surface roughness and porosity owing to the presence of ZnO nanoparticles.

* Context.--It is unclear if preimplantation frozen section biopsy correlates with outcomes after deceased donor kidney transplantation. Objective.--To assess if chronic histologic changes on the preimplant frozen section correlates with graft loss and estimated glomerular filtration rate independently of kidney donor profile index (KDPI). Design.--Seven hundred three preimplantation biopsies were reviewed and a Banff sum score was calculated using glomerular sclerosis, interstitial fibrosis, vascular intimal thickening, and arteriolar hyalinosis. The posttransplant outcomes were compared for preimplantation biopsy Banff sum 0-1, 2-3, and 4-9. The cohort was also stratified by KDPI 85 or less versus more than 85. Results.--For the entire biopsy cohort, graft survival, estimated glomerular filtration rate at 1 year, and chronic changes on a 1-year posttransplant biopsy were superior in the group with preimplantation Banff sum 0-1. After stratifying by KDPI, the Banff sum no longer correlated with graft survival. In a univariate mode, using the Banff sum score as a continuous variable, a higher Banff sum score was significantly associated with graft failure (P = .03); however, after adjusting the KDPI, the Banff sum score no longer correlated with graft failure (P = .45). The 1-year estimated glomerular filtration rate and 1-year biopsy changes were superior in the group with Banff sum 0-1 only in the cohort with KDPI 85 or less. Conclusions.--In donor kidneys used for transplant, preimplantation biopsy chronic changes correlate with estimated glomerular filtration rate and biopsy findings at 1 year, but biopsies with mostly mild chronicity and Banff sum scores less than or equal to 5 did not impact graft survival beyond KDPI., The discard rate for deceased donor kidneys in the United States has been increasing over the last decade. (1) The current overall discard rate for deceased donor kidneys is 18.9%. [...]

Background: Alternate complement dysregulation postrenal transplantation can result in thrombotic microangiopathy (TMA). There is a scarcity of data regarding outcomes based on the timing of TMA post‐transplant, coupled with a lack of follow‐up biopsy findings post TMA diagnosis. This study aims to assess allograft and patient outcomes in individuals developing early TMA, defined within 4 months post‐transplantation, and explore any differences in follow‐up surveillance biopsies compared to a non‐TMA group. Design: This is a single center retrospective study between January 1, 2002 and October 10, 2019. Patients who developed TMA within 4 months post‐transplantation were compared to a propensity matched non‐TMA group. Results: Thirty‐one patients developed TMA within 4 months of renal transplantation. Index TMA biopsy featured noticeable glomerular, and vascular lesions along with acute tubular injury. Four‐month surveillance biopsy showed significant glomerulitis, transplant glomerulopathy and chronic interstitial fibrosis as compared to non‐TMA group. However, at 1 year, these differences were no longer significant. There was no significant difference in patient survival (TMA vs. non‐TMA, p = 0.083); however, death censored graft survival was significantly lower in the TMA group (p < 0.001). TMA patients had a significantly lower estimated glomerular filtration rate at 4 months and at 1 year as compared to the non‐TMA group. Conclusion: Early onset TMA post renal transplant leads to decreased renal function and lower graft survival. Early recognition and prompt treatment may help in reducing the adverse outcomes.

Background: Inadequate adherence to prescribed immunosuppressive medication regimens among kidney transplant recipients is common, yet interventions are needed to support patients in sustaining adequate adherence to prescribed regimens and achieving optimal transplant outcomes. Objective: We examined the preliminary fidelity of a transplant center-based, multifaceted adherence monitoring strategy known as TAKE IT. Methods: The TAKE IT strategy includes: (1) routine, online, monthly patient self-report adherence assessments; (2) care alerts directed to nurses; (3) quarterly reports monitoring tacrolimus values and adherence trends; (4) support tools tailored to specific adherence concerns. A 2-arm, patient-randomized trial is underway at two large transplant centers (N=449). To evaluate the initial fidelity of TAKE IT, we investigated patient uptake of monthly adherence assessments during the course of a 3-month period, whether any disparities emerged, and the nature of any reported adherence concerns. Results: Among 202 patients randomized and exposed to TAKE IT for 3-months or more, 81% (164/202) completed an adherence assessment, 73% (148/202) completed at least two, and 57% (116/202) completed all monthly assessments. Overall, 50% (82/164) of kidney transplant recipients reported at least one adherence concern over the 3-month assessment period. The most common barriers were classified as regimen-related (eg, regimen complexity), cognitive (eg, forgetfulness), and medical (eg, side effects). Higher-income participants were more likely to complete all surveys compared to lower-income participants (P=.01). Conclusions: TAKE IT demonstrated 81% (164/202) completion of an adherence assessment, 73% (148/202) completion of at least two, and 57% (116/202) completion of all monthly assessments during this brief, initial observation period. Among those that did respond to the online assessments, the majority demonstrated sustained engagement. Additional monitoring modalities could also be offered to meet patient preferences to ensure all patients’ medication use can be properly monitored. [ABSTRACT FROM AUTHOR]
