New analysis today by @ImperialCollege to look at reduced risk of 40-45% for Omicron associated hospitalizations, also reinforcing the point on the markedly increased dominator of increased infections imperial.ac.uk/media/imperial…
Omicron vs Delta
Scotland: 60% less hospitalizations
England: 40-45% less hospitalizations
South Africa: ~70% less hospitalizations
All adjusted, all point estimates
But that's all very good. washingtonpost.com/world/europe/o…

It's all summarized right here by a great explainer and data scientist
A paper on microplastics accumulating in the brain was just published @NatureMedicine, open-access
I review the background and major implications in a new Ground Truths edition (link in my profile)nature.com/articles/s4159…
The human brain:
—had 7-30 times more accumulation of microparticles (MPs) than the liver or kidney (organs with previously documented high propensity)
—from people with dementia had 5X accumulation of MPs compared with non-dementia
—there was a marked increase of accumulation over recent years
Three new @NEJM reports on #H5N1 today 1. An overview by @MichaelGIsonMD and @DrJeanneM
"urgent need for vigilant surveillance of emerging mutations and assessment of the threat of human-to-human transmission"
2. Report of the 13-year-old Canadian girl who developed acute respiratory failure. Sequence of her H5N1 revealed 3 mutations that may be linked to higher virulence and adaptation to human cell binding
3. Review of 46 cases of mild H5N1 illness by CDC in 2024
We're learning how to control the immune response, like a rheostat, even in the brain. Implications for understanding the basis and potential treatment of autoimmune conditions like multiple sclerosis, #LongCovid, #MECFS, and brain cancer.

An elegant @Nature study by @AkassoglouLab has illuminated our understanding of the role of fibrin (component of blood clots), #SARSCoV2, and brain inflammation in Covid and #LongCovid.
This discovery and more in the new Ground Truths podcast, with transcript, key figures (such as as the one below) and citations. Open-access. Link in my profile.
A clip from our conversation. Unknowingly, @AkassoglouLab was gearing up for understanding this complex pathophysiology for many years before Covid hit
For treatment, it's not just as simple as preventing fibrin clots. It's isolating the pro-inflammatory action of fibrin, targeted by the antibody
