Our most recent article hits particularly close to home for me. Had the OBBB passed 10 years ago, it’s unlikely that I would have been able to attend medical school. The new changes threaten to “make the rich, richer”.

Blood is shared across legal borders to save lives.

Equitable and efficient movement of blood is guided by science and justice and must be insulated from ideologically motivated practices, argue co-authors @jwjacobs12.bsky.social @aabbupdates.bsky.social

🩸Would you want “unvaccinated” blood? Some patients now demand it—and lawmakers are listening.

Our new Annals piece warns why this shift could endanger blood safety, amplify misinformation, and erode public trust.

Check out our recent viewpoint in @jama.com. The appointment of David Geier to lead the “vaccine and autism link” study, the forced resignation of Peter Marks at the FDA, and the overall leadership of RFK Jr. and Trump are literally killing Americans. We must resist this new world.

H and B Blood Antigens are Essential for In Vitro Replication of GII.2 Human Norovirus
Human norovirus (HuNoV) is a major cause of enteric infectious gastroenteritis and is classified into several genotypes based on its capsid protein amino acid sequence and nucleotide sequence of the polymerase gene.

Excited to share our recent study in which we assessed whether iodinated radiocontrast media (as might be given for a CT scan) interferes with ADAMTS13 activity via the gold standard FRET method - it doesn’t, though read the open access paper for caveats. academic.oup.com/ajcp/advance...

Tranexamic acid did not prevent bleeding or increase clotting in this ~600 patient RCT of heme malignancy patients (TXA was given 1 g IV every 8 hours or 1.5 g orally every 8 hours)🤷🏽‍♂️

Which is too bad--we don't have a tonne to offer these patients.. :(

Scientists, academics, researchers: We’re excited to share that @altmetric.com is now tracking mentions of your research on Bluesky! 🧪
There are already many articles for which there is more attention on Bluesky than on other comparable micro-blogging sites, meaning the academic community and the general public have clearly adopted Bluesky as one of its core places to disseminate and discuss new research.

A Place of Joy.

Wonderful article by my mentor showing cognitive biases persist in AI chatbots, replicates known studies on biases in human and AI LLMs for comparison. Evidence that LLMs are inheriting some of our biases, in some cases quite strongly so ai.nejm.org/doi/full/10....
