Five years after the shift to a “bundled” reimbursement system and revised drug labeling for erythrocyte-stimulating agents (ESAs), overall outcomes are no worse—and some outcomes have improved—for hemodialysis patients covered by fee-for-service Medicare, reports a study in JAMA Internal Medicine.

Available evidence shows no consistent benefit of percutaneous angioplasty with stent replacement over medical therapy for patients with atherosclerotic renal artery stenosis (ARAS), concludes an updated systematic review in the Annals of Internal Medicine.

Adjuvant treatment with the oral antiangiogenic drug sunitinib increases disease-free survival but increases toxicity in patients with metastatic renal cell carcinoma (RCC) at high risk of recurrence, reports a trial in The New England Journal of Medicine.

Diabetes has overtaken glomerulonephritis as the most common cause of chronic kidney disease (CKD) in China, according to a research letter in The New England Journal of Medicine.

Using Chinese national hospital and population databases, the researchers analyzed trends in CKD from 2010 through 2015. Based on medical history and laboratory data, cases of CKD were classified as related to diabetes or glomerulonephritis.

For children with febrile urinary tract infections (UTIs), the risk of new renal scarring increases with each hour of delay to antimicrobial treatment, suggests a study in JAMA Pediatrics.

For patients with atrial fibrillation (AF), baseline renal function may influence the risks and benefits of oral anticoagulation with dabigatran versus warfarin, according to a research letter in the Journal of the American College of Cardiology.

Independent of genetic factors, higher body mass index (BMI) is associated with a higher risk of type 2 diabetes, but not of myocardial infarction (MI) or death, suggests a twin study in JAMA Internal Medicine.

For patients on hemodialysis—particularly those with neurologic symptoms—the high risks of carotid endarterectomy (CEA) may outweigh the benefits, according to a study in JAMA Surgery.

The retrospective analysis included data on 5142 dialysis-dependent patients undergoing CEA from 2006 to 2011 drawn from the US Renal Data System. Perioperative and long-term outcomes were assessed at a median follow-up of 2.5 years.

A sudden drop in kidney function in the few months before starting hemodialysis is associated with a threefold increase in the risk of death within the first year on dialysis, reports a study in The American Journal of Kidney Diseases.

Severely obese patients undergoing bariatric surgery are at lower risk of declining kidney function, independent of other factors, reports a study in Kidney International.
