Medtronic plc received FDA premarket approval Friday for use of its Intellis rechargeable and Vanta recharge-free neurostimulators in patients with diabetic peripheral neuropathy (DPN), suddenly tripling the number of spinal cord stimulators approved for the indication. Medtronic’s implantable spinal cord stimulators (SCS) now join Nevro Corp.’s HFX, which has had the distinction since July 2021 of being the only device with FDA approval for DPN, also known as painful diabetic neuropathy (PDN).

A novel dual-action small molecule developed by a team led by scientists at Kyungpook National University (KNU) in Daegu, South Korea, has been shown to improve the neuropathological features of Alzheimer's disease (AD) in mice, the authors reported in the Jan. 18, 2022, edition of Proceedings of the National Academy of Sciences.

Each year, more than 250,000 Americans undergo sinus surgery to treat a range of nose and sinus complaints. Full recovery can take several weeks, during which patients typically use opioids to treat their postoperative pain. Given the risk of opioid addiction, Tivic Health Systems Inc. is testing a bioelectronic device that offers an alternative to potent narcotics following sinus surgery.

Destroying senescent cells in the aging stem cell niche, either genetically or pharmacologically using the small-molecule senolytic ABT-263 (navitoclax; Abbvie Inc.), enhanced hippocampal neurogenesis and cognitive function in mice, a Canadian study led by scientists at the University of Toronto has found.
