Study out last month - risk of blood clots from a COVID infection are far higher than blood clots from the (first dose of the) AstraZeneca COVID vaccine. After infection w/ COVID-19, risk of a blood clot climbs to 30 times in the first week!
The only COVID vaccine with (comparatively very low) blood clot risk was the *first dose* - only from AstaZeneca.

New study confirms far higher risk of blood clots from COVID-19, than from vaccines

A health data study confirms the risk of blood clots is far higher from COVID-19 infection than from vaccination.

So I'm doing this again; my daughter walked for one designer Friday and walks for another tomorrow, and I'm attending as a #photographer for the day to get better angles and work on my skills.
#Fashion art #Toronto is a really cool project bringing together local designers with volunteer models and an interested public to see their wares.
I spent yesterday evening making sure my memory cards were ready and testing autofocus settings.

JCI - N-acetylcysteine reduces the size and activity of von Willebrand factor in human plasma and mice

"NPR interviewed scientists who are looking at microclots found in the blood of people with #LongCOVID. These #microclots are unusual in that they are made up mostly of an abnormal type of fibrin and form unusual shapes called amyloid. These fibrin amyloid microclots may be a biomarker for long COVID. Another group had an article on microclots and long COVID. They suggest the term “spike protein induced thrombotic vasculitis” (SITV) to describe the pathophysiology of long #COVID #clotting."

COVID news and more 5/20/23

This week we are seeing a sort of variant soup again with many different subvariants putting pressure on XBB.1.5, but none that are strong enough to push XBB.1.5 out of first place by itself. This is good news. Variant testing will now be reported by the CDC every two weeks.

"• We studied thrombogenicity using a range of tests, including a novel microfluidic assay.

• Post-COVID syndrome can lead to increased platelet recruitment and larger thrombi under flow.

• The median time of 23 months from symptom onset suggests potential long-term thrombogenicity."

There's another talk - I barely remember it - but IIRC it was interesting. Apparently mast cells can also release extracellular traps.
