What is known? - PCS and ME/CFS are associated with persistent endothelial dysfunction and increased long-term cardiovascular risk. - Neurocognitive symptoms in post-viral syndromes have been linked to impaired neurovascular coupling. - Retinal vessel analysis provides a validated, non-invasive readout of systemic and cerebral microvascular health. What new information does this article contribute? - PCS is characterized by persistent functional and structural retinal microvascular dysfunction - Retinal endothelial dysfunction scales continuously with post-viral disease severity and is most pronounced in patients fulfilling ME/CFS criteria. - Retinal microvascular alterations are linked to inflammatory–endothelial activation and iron dysregulation, identifying a biologically coherent vascular phenotype.

Inducing immunity against cancer via the gut Could a microbe that can smuggle antigens into the immune system of the gut provide a simple way to treat cancers?

Yet another unique way to stimulate cellular immunity against cancer.

“Using the gut immune system to induce cellular immunity is a unique approach,” Shirakawa notes. “And it should be very easy to extend it to other antigen proteins and also infectious diseases.”

Review Article Noninvasive Assessment of Liver Fibrosis Laurent Castera, M.D., Ph.D., Mary E. Rinella, M.D., and Emmanuel A. Tsochatzis, M.D., Ph.D. A figure showing the diagnosis, staging, and progression of liver fibrosis. The NEJM identity sits at the bottom.

The prognosis of liver disease depends on the extent of fibrosis, which is usually staged with the use of liver biopsy. The limitations of biopsy have led to the development of noninvasive tests, which the authors review. Learn more: nej.md/4hwZMgj

Semaglutide and cardiovascular outcomes by baseline and changes in adiposity measurements: a prespecified analysis of the SELECT trial The cardioprotective effects of semaglutide were independent of baseline adiposity and weight loss and had only a small association with waist circumference, suggesting some mechanisms for benefit bey...

The benefit of Ozempic (semaglutide) for protection from major adverse cardiovascular events (MACE) is independent of weight loss magnitude and baseline adiposity, likely related to the GLP-1 anti-inflammatory effect

UBC enzyme technology clears first human test toward universal donor organs for transplantation - UBC News UBC-developed enzymes successfully converted a kidney to universal type O for transplant, marking a major step toward faster, more compatible organ donations.

This is huge news!
UBC has developed an enzyme that can convert donor organs to type O, making them universal.
Normally a using organs of the wrong blood type causes the recipient's immune system to attack the organ, leading to failure.

It is so normalized that I hear it regularly among average to highly informed and scientifically minded people.

In most cases it's something akin to: "seems the most likely" and "well, that one turned out to be true".

It's mind boggling 🤯

The biopsy from this adult kidney transplant recipient shows features of cytomegalovirus (CMV) infection, including prominent enlargement (“cytomegalo-”) of tubular epithelial cells and their nuclei, along with small basophilic inclusions which expand the cell cytoplasm.
