The number of people with diabetes and end-stage kidney disease (ESKD) is increasing worldwide, but it is unknown whether this indicates an increasing risk for ESKD in people with diabetes. We examined temporal trends in the incidence of ESKD within the Australian population with diabetes from 2002 to 2013. ⋯ The age-standardized annual incidence of ESKD increased in Australia from 2002 to 2013 for nonindigenous people with type 2 diabetes but was stable for people with type 1 diabetes. Efforts to prevent the development of ESKD, especially among indigenous Australians and those with early-onset type 2 diabetes, are warranted.

Identification and Prioritization of Quality Indicators for Conservative Kidney Management.
Conservative kidney management is holistic patient-centered care for patients with kidney failure that focuses on delaying the progression of kidney disease and symptom management, without the provision of renal replacement therapy. Currently there is no consensus as to what constitutes high-quality conservative kidney management. We aimed to develop a set of quality indicators for the conservative management of kidney failure. ⋯ Quality of conservative kidney management care is important to patients, caregivers, and health care professionals. However, discordant quality indicator priorities between groups suggested that care providers delivering conservative kidney management may not prioritize what is most important to those receiving this care. Conservative kidney management programs and health care providers can improve the applicability of this consensus-based quality indicator list to their program by further developing and evaluating it for use in their program.

Randomized Controlled Trial
Effects of Intensive Blood Pressure Lowering on Kidney Tubule Injury in CKD: A Longitudinal Subgroup Analysis in SPRINT.
Random assignment to the intensive systolic blood pressure (SBP) arm (<120mmHg) in the Systolic Blood Pressure Intervention Trial (SPRINT) resulted in more rapid declines in estimated glomerular filtration rates (eGFRs) than in the standard arm (SBP<140mmHg). Whether this change reflects hemodynamic effects or accelerated intrinsic kidney damage is unknown. ⋯ Among participants with CKD in SPRINT, random assignment to the intensive SBP arm did not increase any levels of 8 urine biomarkers of tubule cell damage despite loss of eGFR. These findings support the hypothesis that eGFR declines in the intensive arm of SPRINT predominantly reflect hemodynamic changes rather than intrinsic damage to kidney tubule cells.

Kidney stones have been associated with increased risk for end-stage renal disease (ESRD). However, it is unclear whether there is also an increased risk for mortality and if these risks are uniform across clinically distinct categories of stone formers. ⋯ The higher risk for ESRD in recurrent symptomatic compared with incident symptomatic kidney stone formers suggests that stone events are associated with kidney injury. The clinical indication for imaging in asymptomatic stone formers, the correct diagnosis in miscoded stone formers, and the cause of a bladder outlet obstruction in bladder stone formers may explain the higher risk for ESRD or death in these groups.

Comparative Study
Postcontrast Acute Kidney Injury in Pediatric Patients: A Cohort Study.
The risks of iodinated contrast material administered to pediatric patients are not well defined. The purpose of this study was to examine the rates of postcontrast acute kidney injury (AKI), dialysis therapy, and death following administration of intravenous contrast material to pediatric patients. ⋯ Rates of postcontrast AKI, dialysis therapy, and death following contrast-enhanced CT were very low in this pediatric cohort. Although not detectably different, an effect of contrast on these outcomes could not be ruled out.
