Risk of hemorrhagic stroke in warfarin‐treated patients following heart valve replacement: Findings from the MAGPIE study

Ibrain, EarlyView.
Among 568 mechanical heart valve replacement patients in Bangladesh, hemorrhagic stroke occurred in 4.4% with 52% mortality. Severe pulmonary hypertension increased risk 4.4‐fold, and warfarin therapy ≥104 months nearly doubled the risk, highlighting the need for long‐term risk monitoring in anticoagulated valve patients.

Mono‐ and Bivalent Poly(iso‐butylene)‐Alanines for Drug‐Delivery of Nimodipine and Triamcinolone Acetonide

Macromolecular Rapid Communications, EarlyView.
Mono‐ and bivalent‐, alanine‐modified poly‐iso‐butylenes, folding into beta‐sheets, were prepared by living carbocationic polymerization and subsequent endgroup modification. These PIB‐conjugates are useful as solid polymers for the drug release of triamcinolone and nimodipine. ABSTRACT Poly‐iso‐butylene (PIB) is a well known biocompatible polymer with

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

A Rare Case of Partial Aortic Mechanical Valve Thrombosis With Intact Mitral Mechanical Valve Presenting With ST-Elevation Myocardial Infarction Patients

Journal of Investigative Medicine High Impact Case Reports, 2020
The incidence of mechanical valve thrombosis (MVT) is around 0.4 per 100 patient-years. Mitral valve thrombosis has a higher incidence than aortic valve thrombosis with a nearly 5-fold increase. Various factors contribute to MVT. The most common cause of
