High flow nasal cannula (HFNC) can reduce the need for intubation in patients with coronavirus disease-19 (COVID-19) pneumonia induced acute hypoxemic respiratory failure (AHRF), but predictors of HFNC success could be characterized better. C-reactive protein (CRP) and D-dimer are associated with COVID-19 severity and progression. However, no one has evaluated the use of serial CRP and D-dimer ratios to predict HFNC success.

Coronaviruses evade detection by the host immune system with the help of the endoribonuclease Nsp15, which regulates levels of viral double stranded RNA by cleaving 3' of uridine (U). While prior structural data shows that to cleave double stranded RNA, Nsp15's target U must be flipped out of the helix, it is not yet understood whether Nsp15 initiates flipping or captures spontaneously flipped bases. We address this gap by designing fluorinated double stranded RNA substrates that allow us to directly relate a U's sequence context to both its tendency to spontaneously flip and its susceptibility to cleavage by Nsp15.

Background: Despite numerous genetic studies on Infectious Bronchitis Virus (IBV), many strains from the Middle East remain misclassified or unclassified. Genotype 1 (GI-1) is found globally, while genotype 23 (GI-23) has emerged as the predominant genotype in the Middle East region, evolving continuously through inter- and intra-genotypic recombination. The GI-23 genotype is now enzootic in Europe and Asia.

Background: The coronavirus disease 2019(COVID-19) pandemic significantly impacted the lives of patients and healthcare professionals globally. With rapid spread and severe illness, a great deal of healthcare resources including personal, funding, and hospital beds were dedicated to fight the pandemic.
Objectives: This survey looks to characterize how resources were allocated among Canadian cardiac surgery programs, and how this impacted patient care and outcomes.

Qingwen Zhike prescription (QWZK), a traditional Chinese medicine (TCM) hospital prescription developed in response to the corona virus disease 2019 (COVID-19) pandemic, has demonstrated efficacy in clinical practice. Nevertheless, its specific antiviral components and mechanisms of action remain unclear. This study screened the antiviral compounds against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from Qingwen Zhike prescription and explored the underlying mechanism through chemical composition analysis, serum and lung exposure profiles analysis, high-throughput screening, and transmission electron microscopy (TEM) observation.
