Impact of Tele-Coaching During the COVID-19 Pandemic on Risk-Reduction Behavior of Patients with Heart Failure.

Our study assessed the effectiveness of tele-coaching over written information in educating patients with chronic heart failure (CHF) at high risk of hospitalization about corona virus disease 2019 (COVID-19). We analyzed the impact on number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and self-reported behavior change. In April 2020, a tele-coaching module and written summary about COVID-19, risk-reduction measures for prevention of COVID-19, and appropriate consultation of medical attention during the pandemic were integrated into an established tele-coaching program.

Optimized management of urolithiasis by coloured stent-stone contrast using dual-energy computed tomography (DECT).

Background: We analysed in vitro the appearance of commonly used ureteral stents with dual-energy computed tomography (DECT) and we used these characteristics to optimize the differentiation between stents and adjacent stone.

Methods: We analysed in vitro a selection of 36 different stents from 7 manufacturers. They were placed in a self-build phantom model and measured using the SOMATOM® Force Dual Source CT-Scanner (Siemens, Forchheim, Germany).
