RAS inhibitors and COVID-19 severity in hypertensive patients

A new study published in the journal JAMA Cardiology in April 2020 reports that patients with hypertension who are taking medications called ACE inhibitors (ACEI) or ARBs are not at higher risk for death or more severe illness with COVID-19. This conclusion supports current guidelines for the treatment of hypertension during this pandemic.

P-BEST: Fast efficient COVID-19 virus testing before symptoms appear

A highly promising new study published on the preprint server medRxiv in April 2020 reports an efficient new method to conduct high-throughput testing of blood samples for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which is causing the rapidly spreading pandemic of COVID-19 disease throughout the world. The method could revolutionize the diagnosis of new cases before they become symptomatic.

Antibody detection for COVID-19 - promise and risks

Recently, several research groups emphasized how the pervasive screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies may prove pivotal in determining infection seroprevalence in a given population defining previous exposure, screening health care workers, but also identifying highly reactive individuals that may act as donors for the therapeutic use of their convalescent serum.

Supercomputer helps find 64 compounds as potential inhibitors of the COVID-19 protease

A new study published in Chemrxiv in April 2020 describes the identification of 64 compounds that could potentially be inhibitors of replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is causing the current COVID-19 disease pandemic. The research was carried out using a pharmacophore model of an essential viral enzyme, mining data from the Food and Drug Administration (FDA) database of conformations of approved drugs.

Six novel coronaviruses found in bats

While the world grapples with the pandemic, which has spread to 185 countries and territories, infecting more than 2.15 million people and killing more than 143,000 people, a team of researchers at the Smithsonian's Global Health Program has found six novel coronaviruses in bats in Myanmar.

Research shows speed of asymptomatic SARS-CoV-2 transmission in Boston homeless shelter

The coronavirus disease (COVID-19) is straining healthcare resources across the globe, prompting countries to impose social distancing measures to reduce the transmission of the virus. The problem is, the virus can spread even if the infected person has no symptoms, making contact tracing and isolation measures more difficult. Now, a new study reveals the rapidity of asymptomatic SARS-CoV-2 transmission that occurred in a Boston homeless shelter.

Screening blood samples for COVID-19 using artificial intelligence

A promising new study published in the preprint online journal medRxiv in April 2020 shows the potential of artificial intelligence (AI) for developing a patient classifier that can separate patients likely to be negative for COVID-19 from among a pool of suspected patients visiting an emergency room (ER).

Remdesivir drug stops novel coronavirus from replicating

Scientists from the University of Alberta have published findings that the antiviral drug remdesivir prevents replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by inhibiting RNA replication. The study, published in April 2020 in the Journal of Biological Chemistry, follows on the heels of earlier reports from the same lab in February, showing the drug's effectiveness against the related Middle East Respiratory Syndrome (MERS) virus.

Anosmia (loss of smell) confirmed as a clinical feature of COVID-19

Earlier last month, the association of ear, nose, and throat (ENT) specialists in the UK issued a public statement advising patients with a sudden loss of smell or taste to get tested for COVID-19. They cited not only their own observations but those from numerous other ENT consultants the world around. A review of multiple papers on the sinus and nasal symptoms and signs related to the diagnosis of COVID-19, published in April 2020, in the journal Laryngoscope Investigative Otolaryngology, reiterates this finding.
