Whose breath are you breathing? © Radio New Zealand 2022

How much of the air you’re breathing is air someone else exhaled? And in the midst of a pandemic caused by an airborne virus, where are the riskiest places to be? In the first in a series of five stories Farah Hancock reports on hot spots of hazardous air. https://www.rnz.co.nz/news/in-depth/470690/whose-breath-are-you-breathing

Long-term cardiovascular outcomes of COVID-19. Nat Med (2022)

Xie, Y., Xu, E., Bowe, B. et al. Long-term cardiovascular outcomes of COVID-19. Nat Med (2022). https://www.nature.com/articles/s41591-022-01689-3 The cardiovascular complications of acute coronavirus disease 2019 (COVID-19) are well described, but the post-acute cardiovascular manifestations of COVID-19 have not yet been comprehensively characterized. Here we used national healthcare databases from the US Department of Veterans Affairs to build a […]

Jarry, Jonathan. “With COVID-19, Air Is Both the Problem and the Solution” Office for Science and Society McGill University,15 Jan 2022

Jarry, Jonathan M.Sc., “With COVID-19, Air Is Both the Problem and the Solution” Office for Science and Society McGill University,15 Jan 2022 SARS-CoV-2 can linger in the air. Dealing with it can be relatively easy, but first, we have to admit we have a problem https://www.mcgill.ca/oss/article/covid-19/covid-19-air-both-problem-and-solution On March 28, 2020, at the beginning of the […]

Baig, A.M. “Counting the neurological cost of COVID-19.” Nat Rev Neurol 18, 5–6 (2022)

Baig, A.M. Counting the neurological cost of COVID-19. Nat Rev Neurol 18, 5–6 (2022). https://doi.org/10.1038/s41582-021-00593-7 The neurological deficits caused by COVID-19, which were first reported in the early months of 2020, continue to intrigue neurologists and health-care professionals worldwide. As two new studies highlight, these manifestations are frequent and are expected to increase the burden of morbidity and […]

“The SARS-CoV-2 main protease Mpro causes microvascular brain pathology by cleaving NEMO in brain endothelial cells.” Nature Neuroscience volume 24, pages1522–1533 (2021)

Coronavirus disease 2019 (COVID-19) can damage cerebral small vessels and cause neurological symptoms. Here we describe structural changes in cerebral small vessels of patients with COVID-19 and elucidate potential mechanisms underlying the vascular pathology. In brains of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected individuals and animal models, we found an increased number of empty […]

“The Coronavirus in a Tiny Drop” The New York Times, Carl Zimmer and Jonathan Corum. Dec. 1, 2021

Rich graphic simulation of a simulated drop of liquid including the coronavirus and its spike proteins, long mucins, sticky surfactants, and a mixture of molecules from deep lung fluid, showing how the virus survives inside tiny airborne particles (created by Lorenzo Casalino and Abigail Dommer, Amaro Lab, U.C. San Diego) https://www.nytimes.com/interactive/2021/12/01/science/coronavirus-aerosol-simulation.html To better understand the […]

“Ventilation matters: Engineering airflow to avoid spreading COVID-19,” American Institute of Physics

https://phys.org/news/2021-11-ventilation-airflow-covid-.html As we approach two full years of the COVID-19 pandemic, we now know it spreads primarily through airborne transmission. The virus rides inside tiny microscopic droplets or aerosol ejected from our mouths when we speak, shout, sing, cough, or sneeze. It then floats within the air, where it can be inhaled by and transmitted. […]

This study from @CoVcast; @Marks1Guy, @doctimcook and @EuanTovey is the first to explore near-complete exhaled respiratory emissions under a range of experimental conditions. Time to target physiologically generated aerosols? 🔗https://t.co/8bxTkQgCz2 https://t.co/VP7o8AWGFx (https://twitter.com/Anaes_Journal/status/1377138590388342785?s=03)
