Strong recommendations on how to manage renin-angiotensin system inhibitors, including angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, before surgery are lacking because of a lack of evidence, which is mostly limited to data from observational studies. The STOP-or-NOT trial was a large multicentre randomised trial designed to determine whether chronic renin-angiotensin system inhibitors should be continued or discontinued before major noncardiac surgery. As principal investigators of the STOP-or-NOT trial, we discuss the trial's results and how they contribute to the existing literature on management of renin-angiotensin system inhibitors before surgery.

Although much has been learned about the entry mechanism of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), many details of the entry mechanisms of seasonal human coronaviruses (HCoVs) remain less well understood. In the present study, we used 293T cell lines stably expressing angiotensin converting enzyme (ACE2), aminopeptidase N (APN), or transmembrane serine protease 2 (TMPRSS2), which support high-level transduction of lentiviral pseudoviruses bearing spike proteins of seasonal HCoVs, HCoV-NL63, -229E, or -HKU1, respectively, to compare spike processing and virus entry pathways among these viruses. Our results showed that the entry of HCoV-NL63, -229E, and -HKU1 pseudoviruses into cells is sensitive to endosomal acidification inhibitors (chloroquine and NHCl), indicating entry via the endocytosis route.

Background: Guideline-directed medical therapy (GDMT) reduces events in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Despite this impact, underutilization of GDMT persists. This report sought to describe HF management in Canadian outpatients treated at specialized HF clinics (HFCs).

It is established that patients hospitalised with COVID-19 often have ongoing morbidity affecting activity of daily living (ADL), employment, and mental health. However, little is known about the relative outcomes in patients with COVID-19 neurological or psychiatric complications. We conducted a UK multicentre case-control study of patients hospitalised with COVID-19 (controls) and those who developed COVID-19 associated acute neurological or psychiatric complications (cases).

The autonomic nervous system plays a crucial role in regulating physiological processes and maintaining homeostasis through its two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system. Dysregulation of the autonomic system, characterized by increased sympathetic activity and reduced parasympathetic tone, is a common feature in chronic kidney disease (CKD) and cardiovascular disease. This imbalance contributes to a pro-inflammatory state, exacerbating disease progression and increasing the risk for cardiovascular events.
