Clinical TrialMechanical Power Delivered by Noninvasive Ventilation Contributes to Physio-Anatomical and Clinical Responses to Early Versus Late Proning in COVID-19 Pneumonia.
To study: 1) the effect of prone position (PP) on noninvasive ventilation (NIV)-delivered mechanical power (MP) and 2) the impact of MP on physio-anatomical and clinical responses to early versus late PP in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia. ⋯ MP delivered by NIV during initial 24 hours predicts clinical outcomes. PP curtails MP, but cumulative hours of NIV with MP greater than or equal to 17.9 J/min delivered before PP initiation attenuate the benefits of PP.

Clinical Outcomes and Phylogenetic analysis in Reflection with Three Predominant Clades of SARS-CoV-2 Variants.
The pandemic of coronavirus disease 2019 (COVID-19) has a broad spectrum of clinical manifestations. The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) undergoes continuous evolution, resulting in the emergence of several variants. Each variant has a different severity and mortality rate. ⋯ There has been a surge in COVID-19 infection in the city due to the predominant lineages of SARS-CoV-2, B.1.617, Omicron BA.1.17.2 and Omicron BA.5.6, respectively. A higher PCR-Ct value and severity of the Delta variant over Omicron BA.1.17.2 and/or BA.5.2 variants were significantly correlated with a higher death rate in the same order.

Observational Study
Early treatment with low-molecular-weight heparin reduces mortality rate in SARS-CoV-2 patients.
Since the beginning of the SARS-CoV-2 pandemic, millions of people have been infected and died. Different therapeutic approaches have been recommended, but only a few have shown clinical advantages. Low-molecular-weight heparin (LMWH) has been recommended to prevent COVID-19-related thrombo-embolic events. We aimed to evaluate the impact of early treatment with LMWH on hospital admission and death in patients with SARS-CoV-2 infection. ⋯ Early treatment with LMWH was associated with lower mortality in our cohort. Further studies are needed to better assess the role of wider LMWH administration in terms of timing and regimen dose.

Comparative genomics of spike, envelope, and nucleocapsid protein of severe acute respiratory syndrome coronavirus 2.
Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) upsurge sprang up in Wuhan, China, in late December 2019. ⋯ The current research findings may have an implication that facilitates the development of prospective immunization candidates/small pharmacological compounds targeting COVID-19.
