Coronavirus disease 2019 (COVID-19): Multisystem review of pathophysiology
Ann Med Surg (Lond). 2021 Sep;69:102745. doi: 10.1016/j.amsu.2021.102745. Epub 2021 Aug 23.ABSTRACTCoronavirus disease-19 (COVID-19) pandemic is associated with high morbidity and mortality. COVID-19, which is caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS CoV-2), affects multiple organ systems through a myriad of mechanisms. Afflicted patients present with a vast constellation of symptoms, from asymptomatic disease to life-threatening complications. The most common manifestations pertain to mild pulmonary symptoms, which can progress to respiratory distress syndrome and venous thromboembolism. However, in patients with renal failure, life-threatening cardiac abnormalities can ensue. Various mechanisms such as viral entry through Angiotensin receptor (ACE) affecting multiple organs and thus releasing pro-inflammatory markers have been postulated. Nevertheless, the predictors of various presentations in the affected population remain elusive. An ameliorated understanding of the pathology and pathogenesis of the viral infection has led to the development of variable treatment options, with many more that are presently under trial. This review article discusses the pathogenesis of multiple organ involvement secondary to COVID-19 infection in infected patients.PMID:34457265 | PMC:PMC8381637 | DOI:10.1016/j.amsu.2021.102745

In a recent survey by The Economist Intelligence…
Chris EdwardsThe main weapons against COVID-19 are the vaccines developed by Moderna and BioNTech after a decade of their research into mRNA technologies. That research was supported by more than $3 billion of private angel investment and venture capital.Democrats and Republicans both support medical research funding, and Republicans tout the Trump administration ’s Operation Warp Speed. But governments were not the key to mRNA development. Instead, we can thank the leaders and scientists at Moderna and BioNTech and the suppliers of private capital to them, as I discusshere andhere.TheWall Street Journal &r...
Fueled by new evidence that wildfire smoke can carry living microbes and is associated with a local increase in COVID-19 cases, scientists wonder if smoke might spread infectious diseases and worsen their effects
Jeffrey A. SingerPolitical polarization hinders progress against the COVID-19 pandemic.Political polarization may explain why, after former President Trump called the off ‐label use of the anti‐malarial drug hydroxychloroquine a “game‐changer” in the battle against COVID-19 (randomized controlled trials found that isnot the case), public health officials and the mainstream press appear uninterested in the off ‐label use of any other drugs as therapeutics against a COVID infection.For example, impressive data from randomized controlled trials show the off ‐label use of the off‐...
