Is Mitral Valve Repair Superior to Mitral Valve Replacement in Elderly Patients? Comparison of Short‐ and Long‐Term Outcomes in a Propensity‐Matched Cohort

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundBecause of demographic changes, a growing number of elderly patients present with mitral valve (MV) disease. Although mitral valve repair (MV‐repair) is the “gold standard” treatment for MV disease, in elderly patients, there is controversy ...

Impact of Hydrogen Incorporation on Electronic and Magnetic Structure of X2CrNi18‐9 Stainless Steel

Advanced Engineering Materials, EarlyView.
Hydrogen uptake in austenitic stainless steel alters both its electronic and magnetic structure. Seebeck measurements reveal hydrogen‐induced shifts in the electronic density of states, while neutron scattering uncovers nanoscale inhomogeneities that grow upon hydrogen incorporation, with the most pronounced effect observed in the PBF as‐built state ...

The Price of Redo Mitral Valve Replacement: Determinants of Major Adverse Postoperative Events

Journal of Cardiovascular Development and Disease
Background: Redo mitral valve replacement is a high-risk operation in which early mortality alone may underestimate postoperative burden. We evaluated whether concomitant tricuspid valve repair independently increases major adverse postoperative events ...

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.
