Thermally Induced Solid-Phase Quasi-Intramolecular Redox Reactions of [Hexakis(urea-)iron(III)] Permanganate: An Easy Reaction Route to Prepare Potential (Fe,Mn)O Catalysts for CO Hydrogenation.

Research on new reaction routes and precursors to prepare catalysts for CO hydrogenation has enormous importance. Here, we report on the preparation of the permanganate salt of the urea-coordinated iron(III), [hexakis(urea-)iron(III)]permanganate ([Fe(urea-O)](MnO)) via an affordable synthesis route and preliminarily demonstrate the catalytic activity of its (Fe,Mn)O thermal decomposition products in CO hydrogenation. [Fe(urea-O)](MnO) contains O-coordinated urea ligands in octahedral propeller-like arrangement around the Fe cation.

Cerebral monitoring during carotid endarterectomy using transcranial cerebral oximetry.

This study aimed to evaluate the outcomes of carotid endarterectomies (CEA) performed using transcranial cerebral oximetry as cerebral monitoringMETHODS: This single-center study included patients treated surgically for significant stenosis of the internal carotid artery (ICA) from January 2012 to December 2017RESULTS: Of the 654 patients, 267 were asymptomatic, and 387 were symptomatic. Eversion CEA was performed in 64.8 %, and patched conventional CEA in 35.

Left atrial appendage strain rate is associated with documented thromboembolism in nonvalvular atrial fibrillation.

Background: The left atrial appendage (LAA) strain and strain rate have not yet been studied in the prediction of cardiac thromboembolism. Therefore, this study aimed to evaluate the significance of LAA strain and strain rate as assessed by speckle-tracking imaging in relation to documented thromboembolic events.

Methods: A group of 80 patients with a mean age of 65 years who were referred for electrical cardioversion of nonvalvular atrial fibrillation was retrospectively analyzed.

Severe structural deterioration of small aortic bioprostheses treated with valve-in-valve transcatheter aortic valve implantation.

Objectives: The aim of this study was to evaluate outcomes of valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) in patients with degenerated small bioprostheses.

Methods: Outcomes of consecutive 27 high-risk patients (logistic EuroSCORE 35.5 ± 18.

[Leiomyoma of external iliac vein].

Authors present a case report of a patient who was diagnosed with a tumour of external iliac vein. Excision of venous wall with tumour and reconstruction of external iliac vein with venous patch was performed. Postoperative course was without complication.
