Cardiovascular complications in the course of COVID-19 - lessons learned and implications for the future care of patients with viral respiratory diseases: Data from a single center retrospective observational study.

Background: Factors associated with cardiovascular complications of COVID-19 remain understudied.

Objectives: Here we investigate the occurrence and risk factors of arrythmias, myocardial infarction and/or stroke, and thromboembolism in the course of COVID-19.

Methods: We have performed an observational study with prospectively designed data collection.

The prevalence and predictors of pulmonary lesions in paediatric patients with coronavirus disease 2019 - a brief report.

Purpose: There are currently only scarce data available describing imaging manifestations in children with COVID-19. The aim of this study was to analyse pulmonary lesions on chest radiography (CXR) in paediatric patients infected with SARS-CoV-2 and to compare the CXR results with clinical and laboratory data.

Material And Methods: In this prospective single-centre study we included 118 consecutive paediatric patients with COVID-19.

How to follow-up a patient who received tocilizumab in severe COVID-19: a case report.

Background: COVID-19 is characterized by fast deterioration in the mechanism of cytokine storm. Therefore, treatment with immunomodulating agents should be initiated as soon as hyperinflammation is established. Evidence for the use of tocilizumab (TCZ) in COVID-19 is emerging, but the drug in this setting is used "off label" with limited data on both effectiveness and safety.
