Dexamethasone shown to upregulate innate and adaptive immune responses in COVID-19 acute respiratory distress syndrome patients

In a new study, researchers used per protocol bronchoalveolar lavage fluid (BALF) samples after intubation to evaluate the transcriptomic profiles of the local pulmonary host responses during early-stage severe coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (CARDS), non-COVID-19 ARDS, and sepsis.

Study reveals aerosol transmission of SARS-CoV-2 via floor drains

A new study investigated COVID-19 cases in an apartment complex in South Korea and explored the possibility of aerosol transmission without direct contact between infected individuals with the help of molecular phylogenetic analysis and epidemiological surveillance.

Rapid antigen test for SARS-CoV-2 proves to be highly accurate for pediatric populations

In a large prospective study of just over 1,000 patients ages 17 and younger who were seen at the Baltimore Convention Center Field Hospital (BCCFH) testing site during a seven-month period last year, researchers from Johns Hopkins Medicine and collaborating institutions report that a rapid antigen test for SARS-CoV-2 — the virus that causes COVID-19 — proved highly accurate when compared to the established standard virus detection method: the polymerase chain reaction (PCR).

Faster and more affordable method for detecting adulteration of meat products

Meat and sausage products can be found on the shelves of every grocery store. Although sometimes not everything that the manufacturer listed on the package is true. Expensive types of meat, such as beef, are often substituted with cheaper poultry.

Investigating the presence of human rRNA in the SARS-CoV-2 genome

In a new study, a team of researchers investigated the existence of SARS-CoV-2-host chimeric RNA and described two novel human-derived genomic insertions present in the circulating variants of SARS-CoV-2.

Plasma SARS-CoV-2 viral RNA as a valuable biomarker for SARS-CoV-2 infection in the lungs

Researchers recently evaluated respiratory syndrome coronavirus 2 (SARS-CoV-2) viral RNA (vRNA) levels in longitudinal samples collected simultaneously from mechanically ventilated coronavirus disease 2019 (COVID-19) patients and analyzed their connections and relationships with clinical outcomes.
