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

New and Emerging Artificial Urinary Sphincters for Male Stress Urinary Incontinence: From Gold Standard to Next Generation

Neurourology and Urodynamics, EarlyView.
ABSTRACT Introduction For more than four decades, the AMS‐800 has remained the clinical benchmark device for the treatment of male stress urinary incontinence (SUI). Although it remains the gold standard for male SUI, the AMS‐800 has continued to have limitations such as suboptimal post‐operative continence rates, fixed hydraulic pressure, need for ...

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 ...
