Bioprosthesis versus Mechanical Valve Heart Prosthesis: Assessment of Quality of Life

open access: yes, 2020
Background: The aim of this study was to evaluate the QoL of patients undergoing heart valve replacement using the SF-36 questionnaire, compare it between patients with mechanical prosthesis and patients with bioprosthesis, and correlate the results with

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

open access: yesPolymer 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 ...

Exploiting Device Deformability for Fluid and Particle Manipulation

open access: yesSmall, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Quantifying Shear Stresses in Tissue Engineered Aortic Heart Valves

open access: yes, 2022
Present heart valve prosthesis have limitations such as capability to grow, repair and remodel post implantation. Tissue engineering offers to be a promising alternative to overcome these limitations.

Even a single positive blood culture may matter – A case of prosthetic valve infective endocarditis caused by Corynebacterium kroppenstedtii

open access: yesIDCases
Corynebacterium is a skin commensal bacterium that can contaminate blood cultures. It is however also a rare cause of infective endocarditis (IE). Here we report a case of Corynebacterium kroppenstedtii aortic prosthesis IE in a 76-year-old man where ...
