Reaction slowing observed in dialyzed patients results from deficits in initiating and sustaining motor response mobilization. The present study aimed at investigating whether these deficits are reversible following successful kidney transplantation. To achieve this goal, behavioral and electrophysiological (EEG) data were assessed from healthy control participants as well as kidney transplant and dialyzed patients performing a series of reaction time tasks. The results demonstrated that in patients who received kidney transplant a normalization of response latencies and brain preparatory activity was observed. At the same time, when compared to healthy individuals, increased attention engagement was observed in both clinical groups of patients. No behavioral and electrophysiological indices of impaired monitoring were observed in any of the clinical groups.

Tacrolimus-induced thrombotic microangiopathy (TMA) after heart and lung transplantation successfully treated with eculizumab.

Pulmonary, Critical Care and Cardiothoracic Surgery, Northwell Health Systems, 300 Community Dr, Manhasset, NY 11030, United States of America.
Introduction: Tacrolimus-induced thrombotic microangiopathy (TMA) causing acute kidney injury (AKI) without systemic features is a rare entity, particularly after non-renal solid organ transplantation.
Case Report: We describe the case of a patient with AKI after combined heart and lung transplantation. Renal biopsy revealed acute thrombotic microangiopathy which ultimately prompted initiation of eculizumab, a monoclonal antibody targeted against complement C5, with subsequent recovery in renal function.

Background: Adoptive transfer of autologous regulatory T cells (Tregs) is a promising therapeutic strategy aimed at enabling immunosuppression minimization following kidney transplantation. In our phase 1 clinical trial of Treg therapy in living donor renal transplantation, the ONE Study (ClinicalTrials.gov: NCT02129881), we observed focal lymphocytic infiltrates in protocol kidney transplant biopsies that are not regularly seen in biopsies of patients receiving standard immunosuppression.

Background: Postoperative acute kidney injury (AKI) and chronic kidney disease (CKD) following pediatric liver transplantation (PLT) have not been comprehensively studied. This study aimed to evaluate the correlation between AKI and both 1-year CKD and mortality.
Methods: This retrospective study included 132 children aged between 3 months and 12 years who underwent PLT between 2017 and 2021.
