Isolated cardiac sarcoidosis: A clinical challenge.

Sarcoidosis is an inflammatory disease characterised by non-caseating granulomas of unclear aetiology. Isolated cardiac sarcoidosis (ICS) is rare and occurs when there is granulomatous infiltration of myocardial tissue without evidence of extracardiac sarcoidosis. The heterogeneity in clinical manifestations often presents a diagnostic challenge which leads to delays in treatment initiation.

Fragmentation of the QRS Complex Is Associated with Right Ventricular Dilatation and Mortality in Critically Unwell Coronavirus Disease 2019 Patients.

Background: QRS fragmentation (fQRS) is a depolarization disorder that can be detected on routine electrocardiography (ECG). Current evidence suggests that fQRS is a prognosticator of adverse cardiovascular events. This study aimed to assess the relationship between fQRS and all-cause mortality in critically unwell coronavirus disease 2019 (COVID-19) patients and to investigate the significance of associated abnormalities on echocardiography.

The impact of anticholinergic burden on clinical outcomes in older hospitalised surgical patients.

Polypharmacotherapy is an ever-increasing issue with an ageing patient population. Anticholinergic medications make up a large proportion of patient medication but cause significant side effects, contributing to well-documented issues within the older population and in hospital medicine. This review explores the documented impact of anticholinergic burden in older surgical patients on postoperative delirium, infection, length of stay and readmission, urinary retention, ileus and mortality.
