In an Editorial, O’Shaughnessy and Lafayette suggest that patients with IgA nephropathy who receive treatment with corticosteroids should be closely monitored for the development of adverse events.



Rapid revascularization may improve clinical outcomes in patients with ischemic stroke. In a randomized clinical trial of 381 patients with acute ischemic stroke and large vessel occlusion in the anterior circulation, Lapergue and colleagues found that thrombectomy with contact aspiration and thrombectomy using a stent retriever technique resulted in similar rates of revascularization.

Under Medicare’s Physician Value-Based Payment Modifier Program, physician practices receive penalties or bonuses based on quality and costs of care.
