Kidney transplantation from donors after cardiac death (DCD) provides similar graft survival to donors after brain death (DBD) in adult recipients. However, outcomes of DCD kidneys in pediatric recipients remain unclear, primarily because of limited sample sizes. ⋯ A significant increase in DCD graft loss starting 4 years after transplantation motivates a cautious approach to the use of DCD kidneys in children, in whom long-term graft survival is of utmost importance.

Relationship between blood pressure and incident chronic kidney disease in hypertensive patients.
Hypertension is an important cause of chronic kidney disease (CKD). Identifying risk factors for progression to CKD in patients with normal kidney function and hypertension may help target therapies to slow or prevent decline of kidney function. Our objective was to identify risk factors for development of incident CKD and decline in estimated GFR (eGFR) in hypertensive patients. ⋯ We found that time-varying systolic BP was associated with incident CKD, with an increase in risk above a systolic BP of 120 mmHg among individuals with hypertension.

Randomized Controlled Trial Multicenter Study Comparative StudyWarfarin in atrial fibrillation patients with moderate chronic kidney disease.
The efficacy of adjusted-dose warfarin for prevention of stroke in atrial fibrillation patients with stage 3 chronic kidney disease (CKD) is unknown. ⋯ Among atrial fibrillation patients participating in the Stroke Prevention in Atrial Fibrillation III trials, stage 3 CKD was associated with higher rates of ischemic stroke/systemic embolism. Adjusted-dose warfarin markedly reduced ischemic stroke/systemic embolism in high-risk atrial fibrillation patients with stage 3 CKD.

Randomized Controlled Trial Comparative StudyBelatacept-versus cyclosporine-based immunosuppression in renal transplant recipients with pre-existing diabetes.
Renal transplant recipients with pre-existing diabetes (PD) have reduced graft survival and increased risk of mortality and ischemic heart disease compared with nondiabetic transplant recipients. To assess the effect of belatacept in this high-risk group, we evaluated outcomes of the subpopulation with PD from previously published BENEFIT and BENEFIT-EXT trials. ⋯ In post hoc analysis of patients with PD, patient/graft survival and renal function at 12 months were numerically higher with belatacept versus cyclosporine, but not statistically significant. Further study is necessary to confirm the benefits belatacept may provide in these patients.

Multicenter StudyEffectiveness and safety of warfarin initiation in older hemodialysis patients with incident atrial fibrillation.
Although generally recommended in atrial fibrillation (AF) patients, the effectiveness and safety of oral anticoagulation in dialysis patients with AF is unknown. ⋯ Although we confirmed association between warfarin use and hemorrhagic stroke in dialysis patients with AF, we found no association between warfarin use and ischemic stroke. Adequately powered randomized trials are required to conclusively determine the risks and benefits of the studied warfarin indication in hemodialysis patients.
