This is concerning.

When controlling for age, body habitus, and other variables, people who had covid had sizes of key brain structures 4 standard deviations below average.

The hippocampal gyrus is responsible for memory, in part.

These changes were not found to be different whether one was hospitalized or not.

The one metric where size increased post covid- ventricle volume- is a good marker for loss of brain matter. This usually increases with age. ImageImage
And before people tell you this was unexpected- no. This was predictable. Furin cleavage sites confer neurotropism and this was my primary concern with the virus. With the knowledge it had a Sag, the situation appeared more dire. Downplayers are culpable. Image
I have been trying to convey this clear risk to people like Prasad and Munro who advocate to have kids in classrooms despite circulating neurotropic viruses with furin cleavage sites and superantigens. Image
Whether intentional or not, it seems to me all pathologically salient features of the virus like the Furin cleavage Site and SEB Superantigen were downplayed bc they went hand in hand with stoking the possibility of modifications a lá Gain of Function, whether true or not.

@Bryce_Nickels This is absolutely false because he made a “noble lie” and said the N 95s would not work for the public to the public in order for there to be greater supply to healthcare workers only. This backfired.
@Bryce_Nickels The ethical approach was the truth. This is a similar noble lie by omission that the WHO made when they refused to declare Covid as airborne in order for impoverished health systems to provide “adequate” PPE per their regulations according to WHO standards
@Bryce_Nickels The end result was workers in impoverished systems were being given “adequate “PPE for droplet transmission, and many of them died, including sadly many in New York City.

I think the decrease in childrens performance following 2020 was due to the Neurological harm after they were coaxed into unsafe classrooms before vaccination

I think this will remain the dominant effect due to Covid's neurotropism on reinfection

Some people are encouraged to obfuscate the risk of kids getting infected and they will continue to do so

16.1% of reinfected children got Long covid after reinfection compared to 12.1% with only 1 infection

More reinfected individuals had persistent anosmia, an indicator of neuroinflammation

I was a fellow at the National Cancer Institute for 4 years in immunotherapy of cancer

They paid for my PhD

I am happy to explain hypotheses for a potential SARS Cov 2 based increased risk of cancer:

1/4
There are multiple ways a virus can cause cancer directly & indirectly

One indirect way is by tempering immunity

The immune system surveils for wayward, cancerous, and precancerous cells, and kills them

SARS Cov 2 ages & dysregulates T cells
2/4
A second broad yet direct category is by Viral Oncogenes or mutagenesis

Some Viruses have proteins that can change expression or function of host genes & accelerate the formation of tumors by preventing cell death

Some viruses cause DNA errors to accumulate

In 2021 on TWIV, Vincent Raccaniello said my claims of T cell exhaustion risk were "Twitter Science™"

In 2024 I am pleased to see T cell exhaustion is Science™, Nature Immunology™, and Nature Medicine™ Science
Raccaniello is arrogant enough to the extent to reject an accurate scientific hypothesis on twitter and his TWIV podcast to the detriment of the public, without knowing enough about the subject It was completely irresponsible

Are you feigning ignorance? It was a perjorative.

Massachusetts General Hospital has declared a critical incident under a "capacity disaster"

Some professors at Harvard assured the crisis phase of covid was over.

I sure would be embarrassed if shown up by someone I keep proclaiming superiority over.

patch.com/massachusetts/…
Especially if I was a wunderkind Harvard professor in Cardiology.

That would mean I know at least as much immunology as a professor of immunology at a state school
Which Mark has the better takes in immunology?
