Towards real-time cardiovascular magnetic resonance-guided transarterial aortic valve implantation: In vitro evaluation and modification of existing devices

Journal of Cardiovascular Magnetic Resonance, 2010
Background Cardiovascular magnetic resonance (CMR) is considered an attractive alternative for guiding transarterial aortic valve implantation (TAVI) featuring unlimited scan plane orientation and unsurpassed soft-tissue contrast with simultaneous device

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

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

IDCases
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 ...

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 ...

Weathering the storms of climate change: Preparing persons with disabilities and the physiatrists who provide their care for extreme hurricanes

PM&R, EarlyView.
Abstract Climate‐driven disasters have disproportionate and often devastating consequences on individuals with disabilities. Warming ocean and air temperatures are fueling more extreme tropical cyclones, further endangering those living in at‐risk regions.

Non infective severe aortic paravalvular leakage 7 years after surgery: the role of suture technique

Journal of Cardiothoracic Surgery, 2011
We report a case of redo aortic prosthesis replacement for a severe paravalvular leak (PVL) in a man operated with continuous suture technique 7 years earlier. The severe aortic regurgitation was due to the rupture of the suture.

Evidence Suggests Prophylactic Antibiotics May Be Unnecessary in Anorectal Surgery—A Systematic Review and Meta‐Analysis

World Journal of Surgery, EarlyView.
Current evidence does not support the routine use of prophylactic antibiotics in uncomplicated anorectal procedures. However, the certainty of evidence is limited by small sample sizes, methodological heterogeneity, and limited number of available studies. Large‐scale randomized trials are required to strengthen this evidence base.

Mitral regurgitation in patients with severe aortic stenosis: Diagnosis and management [PDF]

, 2018
Severe aortic stenosis (AS) and mitral regurgitation (MR) frequently coexist. Although some observational studies have reported that moderate or severe MR is associated with higher mortality, the optimal management of such patients is still unclear ...
