Telemedical cardiac risk assessment by implantable cardiac monitors in patients after myocardial infarction with autonomic dysfunction (SMART-MI-DZHK9): a prospective investigator-initiated, randomised, multicentre, open-label, diagnostic trial.

Background: Cardiac autonomic dysfunction after myocardial infarction identifies patients at high risk despite only moderately reduced left ventricular ejection fraction. We aimed to show that telemedical monitoring with implantable cardiac monitors in these patients can improve early detection of subclinical but prognostically relevant arrhythmic events.

Methods: We did a prospective investigator-initiated, randomised, multicentre, open-label, diagnostic trial at 33 centres in Germany and Austria.

[Recurrent intracerebral haemorrhage in a 24-year-old female patient].

A 24-year-old female patient from Sierra Leone was referred to the authors' hospital after several unclear intracerebral bleeding events and an echogenic structure on the aortic valve. The patient was receiving oral anticoagulation therapy due to paroxysmal atrial fibrillation and left ventricular noncompaction. Fluorescence in situ hybridization in combination with polymerase chain reaction and sequencing revealed infective endocarditis of the mitral and aortic valve caused by Bartonella quintana.

App-Based Tracking of Self-Reported COVID-19 Symptoms: Analysis of Questionnaire Data.

Background: COVID-19 is an infectious disease characterized by various clinical presentations. Knowledge of possible symptoms and their distribution allows for the early identification of infected patients.

Objective: To determine the distribution pattern of COVID-19 symptoms as well as possible unreported symptoms, we created an app-based self-reporting tool.

Mutations in the mitochondrial thioredoxin reductase gene TXNRD2 cause dilated cardiomyopathy.

Aims: Cardiac energy requirement is met to a large extent by oxidative phosphorylation in mitochondria that are highly abundant in cardiac myocytes. Human mitochondrial thioredoxin reductase (TXNRD2) is a selenocysteine-containing enzyme essential for mitochondrial oxygen radical scavenging. Cardiac-specific deletion of Txnrd2 in mice results in dilated cardiomyopathy (DCM).
