As of July 28, 2020, 1840 clinical trials were registered globally, with 1001 clinical trials recruiting patients for COVID-19 management.1
Despite this large number, only 30 trials have been published as peer-reviewed or preprint publications.2
Media reports and prepublications on medRxiv and bioRxiv represent the most frequent mechanism for data sharing, with wide public reach and usually with little detail. However, with inadequate details on the trials and only superficial scrutiny by the public and scientific decision makers, the consequences have had disastrous effects on other clinical trial funding, permissions, recruitment, and interpretation.
He [Mills, a co-author] traces the problem in part to the unprecedented way science is being communicated during the pandemic.
Instead of a sober exchange of peer-reviewed journal papers, research is often first published on “pre-print” websites or in news releases without review, then reported by journalists and spread through social media.
“Never before have we seen a medical scenario become such a public topic, where you have the president of the United States and the president of other countries weighing in on whether a drug works or not,” he noted. “And then you have the public weighing in on whether they agree with that individual, based on their own politics. This is unheard-of.”

In this article, we provide an overview of the coronavirus life cycle with an eye toward its notable molecular features and potential targets for therapeutic interventions. Much of the information presented is derived from studies of the betacoronaviruses MHV, SARS-CoV, and MERS-CoV, with a rapidly expanding number of reports on SARS-CoV-2. The first portion of the review focuses on the molecular basis of coronavirus entry and its replication cycle. We highlight several notable properties, such as the sophisticated viral gene expression and replication strategies that enable maintenance of a remarkably large, single-stranded, positive-sense (+) RNA genome and the extensive remodeling of cellular membranes to form specialized viral replication and assembly compartments. The second portion explores the mechanisms by which these viruses manipulate the host cell environment during infection including diverse alterations to host gene expression and immune response pathways.

A slew of detailed studies has now quantified the increased risk the virus poses to older people, men, and other groups.

If there is one thing that social media had demonstrated, it is that knowledge and expertise, real or imagined, is high non-transferable across fields of study.

Neurological consequences of COVID-19: what have we learned and where do we go from here?
A device using a paddle to deliver mild shocks to the tongue, alongside sound therapy, can reduce tinnitus for up to 1 year, researchers claim.
It’s one of the pandemic’s puzzles: Most people infected by SARS-CoV-2 never feel sick, whereas others develop severe disease or even end up in an intensive care unit clinging to life. Age and preexisting conditions, such as obesity, account for much of the disparity. But geneticists have raced to see whether a person’s DNA also explains why some get hit hard by the coronavirus, and they have uncovered tantalizing leads.
Now, a U.K. group studying more than 2200 COVID-19 patients has pinned down common gene variants that are linked to the most severe cases of the disease, and that point to existing drugs that could be repurposed to help. “It’s really exciting. Each one provides a potential target” for treatment, says genetic epidemiologist Priya Duggal of Johns Hopkins University.
Last week, craving sweets, Colin Purrington remembered the Twinkies.
He'd purchased them back in 2012 for sentimental reasons when he heard that Hostess Brands was going bankrupt and Twinkies might disappear forever.
Caveats.Genetically engineered cells that overproduce ACE2, the receptor the novel coronavirus uses to enter cells, neutralize infection in vitro and mop up inflammatory cytokines in mice.
An awful lot of guesses in the article. How about wild speculation? As the human body adapts to the virus the virus adapts to human bodies? Meaning that the immunity response selects how the virus adapts. With a result of either less deadly strains of virus or more deadly strains that are more infectious.
Abstract
We use COVID-19 case and mortality data from 1 February 2020 to 21 September 2020 and a deterministic SEIR (susceptible, exposed, infectious and recovered) compartmental framework to model possible trajectories of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and the effects of non-pharmaceutical interventions in the United States at the state level from 22 September 2020 through 28 February 2021. Using this SEIR model, and projections of critical driving covariates (pneumonia seasonality, mobility, testing rates and mask use per capita), we assessed scenarios of social distancing mandates and levels of mask use. Projections of current non-pharmaceutical intervention strategies by state—with social distancing mandates reinstated when a threshold of 8 deaths per million population is exceeded (reference scenario)—suggest that, cumulatively, 511,373 (469,578–578,347) lives could be lost to COVID-19 across the United States by 28 February 2021. We find that achieving universal mask use (95% mask use in public) could be sufficient to ameliorate the worst effects of epidemic resurgences in many states. Universal mask use could save an additional 129,574 (85,284–170,867) lives from September 22, 2020 through the end of February 2021, or an additional 95,814 (60,731–133,077) lives assuming a lesser adoption of mask wearing (85%), when compared to the reference scenario.
I read somewhere that 87% of people infected regularly wore masks. That no filter masks are capable preventing coronavirus from getting through.kmich wrote: ↑Sun Oct 25, 2020 8:05 pm Modeling COVID-19 scenarios for the United States
