Early mortality after aortic valve replacement with mechanical prosthetic vs bioprosthetic valves among Medicare beneficiaries: a population-based cohort study.
The researchers compared early mortality after aortic valve replacement (AVR) between the recipients of mechanical and bioprosthetic aortic valves. Among 66,453 Medicare beneficiaries who received AVRs, use of mechanical valves was associated with a higher risk for death on the date of surgery and within 30 days compared with the bioprosthetic aortic valves. However, this applied only to those who underwent concurrent AVR and coronary artery bypass graft but not isolated AVR.

Effectiveness of mesh compared with nonmesh sling surgery in Medicare beneficiaries.
This study assessed the effectiveness of mesh compared to nonmesh slings in the surgical treatment of female incontinence. It found that overall rates of complications were similar for patients undergoing either mesh or nonmesh sling procedures. However, patients undergoing the nonmesh procedure were more likely to require a subsequent intervention for bladder outlet obstruction.
