Effect of Restorative Neurostimulation on Major Drivers of Chronic Low Back Pain Economic Impact.
High-impact chronic low back pain (CLBP) correlates with high healthcare resource utilization. Therapies that can alter impact status may provide beneficial long-term economic benefits. An implantable restorative neurostimulation system (ReActiv8, Mainstay Medical) designed to over-ride multifidus inhibition to facilitate motor control restoration, thereby resolving mechanical low back pain symptoms, has shown significant durable clinical effects in moderately and severely impacted patients. ⋯ In addition to clinically meaningful improvements in pain and function with long-term durability, the overwhelming majority of patients transitioned from a high- to a no- or low-impact CLBP state. This is typically associated with significantly lower healthcare-utilization levels. The of recovery trajectory is consistent with a restorative mechanism of action and suggests that over the long term, the improvement in these health states will be maintained.

101 30-Day Outcomes of Resolute Onyx Stent for Symptomatic Intracranial Stenosis: A Multicenter Propensity-Score Matched Comparison With SAMMPRIS Trial.
Symptomatic intracranial atherosclerotic disease (sICAD) is estimated to cause over 10% of strokes annually in the US alone. Previous investigations employing stenting, most notably SAMMPRIS trial, have produced unfavorable results in regards to both periprocedural complications and risk of recurrent stroke. However, newer generation balloon-mounted drug-eluting stents (BM-DES) have been hypothesized to harbor several technical advantages that may confer improvements in these critical metrics. ⋯ Patients treated with RO-ZES had a decreased rate of 30-day major complications in comparison to SAMMPRIS. Further large-scale prospective studies are warranted to evaluate the safety and efficacy of RO-ZES for the treatment of sICAD.
