High-dimensional characterization of post-acute sequalae of COVID-19.

Nature 2021 Apr 22. Epub 2021 Apr 22.

Clinical Epidemiology Center, Research and Development Service, VA Saint Louis Health Care System, Saint Louis, MO, USA.

The acute clinical manifestations of COVID-19 are well characterized; however, its post-acute sequalae have not been comprehensively described. Here, we use the national healthcare databases of the US Department of Veterans Affairs to systematically and comprehensively identify 6-month incident sequalae including diagnoses, medication use, and laboratory abnormalities in 30-day survivors of COVID-19. We show that beyond the first 30 days of illness, people with COVID-19 exhibit higher risk of death and health resource utilization. Read More

Intradermal delivery of a synthetic DNA vaccine protects macaques from Middle East respiratory syndrome coronavirus.

JCI Insight 2021 Apr 22. Epub 2021 Apr 22.

Vaccine and Immunotherapy Center, The Wistar Institute, Philadelphia, United States of America.

Emerging coronaviruses from zoonotic reservoirs including severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been associated with human-to-human transmission and significant morbidity and mortality. Here we study both intradermal (ID) and intramuscular (IM) two-dose delivery regimens of an advanced synthetic DNA vaccine candidate encoding a full-length MERS-CoV Spike (S) protein, which induced potent binding and neutralizing antibodies, as well as cellular immune responses in rhesus macaques. In a MERS-CoV challenge, all immunized rhesus macaques exhibited reduced clinical symptoms, lowered viral lung load, and decreased severity of pathological signs of disease compared to controls.

Comparative phylogenetic analysis of SARS-CoV-2 spike protein-possibility effect on virus spillover.

Brief Bioinform 2021 Apr 22. Epub 2021 Apr 22.

Queensland Biosciences Precinct, The University of Queensland, St Lucia 4072, Queensland, Australia.

Coronavirus disease 2019 has developed into a dramatic pandemic with tremendous global impact. The receptor-binding motif (RBM) region of the causative virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), binds to host angiotensin-converting enzyme 2 (ACE2) receptors for infection. As ACE2 receptors are highly conserved within vertebrate species, SARS-CoV-2 can infect significant animal species as well as human populations. Read More

Nasal cannula or high-flow oxygen for patients with COPD in acute respiratory distress?

Nursing 2021 May;51(5):52-57

At the University of Pittsburgh Medical Center Presbyterian Hospital in Pittsburgh, Pa., Frederick J. Tasota is an RN educator and Terri L. Kress, Tiffany L. Conlin, and Natalie M. Scarmack are advanced clinical education specialists.

Abstract: There may be some confusion regarding the use of supplemental oxygen in patients with chronic obstructive pulmonary disease (COPD) who are experiencing acute respiratory distress. This article addresses a common nursing misconception regarding the use of high-flow oxygen administration via non-rebreather masks instead of low-flow oxygen administration via nasal cannulas in patients with COPD who are in acute respiratory distress, an issue that was investigated in a simulation education exercise and survey of the nursing staff at the authors' facility.
