Health-related quality of life improved more after heart transplantation than after long-term mechanical circulatory support over time

Claude has discovered a previously unknown enzyme system hidden in the DNA of bacteriophages. Beside the enzyme’s gene sits a long array of repeating DNA—a structure that looks somewhat similar to CRISPR.

We don’t yet understand what this system does, but only a handful of known systems share its features, and all of them are able to cut, copy, and paste DNA. Historically, the discovery of such programmable systems has helped revolutionize medicine. CRISPR, for instance, is now the foundation of genetic medicines. But it will take much more work to learn what this system does, and whether it can be put to similar use.

"Access to medical knowledge shouldn't depend on geography," said Daniel Nadler, founder and CEO of OpenEvidence.

That's why OpenEvidence and @AnthropicAI are bringing a specialized version of OpenEvidence, free, to clinicians in about 100 low- and middle-income countries, including Uganda, Angola, Sudan, Haiti, and Mongolia. More here: https://t.co/UxdEaHSkla

This is phenomenal and truly transformative. Can’t overemphasize how immense this is. There are several implementation bottlenecks that need to be overcome but this is the necessity of the hour in Global Health.

A recent report published in #JACCAdvances found that cardiologists per 100,000 U.S. population declined alongside substantial workforce aging, despite modest increases in total cardiologist numbers.

🚨New Science Alert!

🫀DCD heart transplantation has expanded rapidly nationwide to more centers & higher-risk recipients. Yet graft failure, mortality & other early outcomes remained stable.

This UNOS analysis supports the robustness & scalability of DCD.

1) Sotatercept is amazing effective for PAH but effects on the RV have been inconsistent. @CircAHA we show that RV contractility truly decreases after sotatercept with no change in RV PA coupling -> the surrogates we’ve chased for years with vasodilators

Valsalva in Echo — Know WHEN to strain vs release

👉 Valsalva (strain) = ↓ preload (LV shrinks)
✔️ HCM → ↑ LVOT obstruction
✔️ MVP → earlier prolapse click
✔️ Diastolic dysfunction → unmasks pseudo-normal

👉 Release = ↑ venous return (RA fills first)
✔️ Bubble study (PFO/ASD) → R→L shunt best seen RIGHT AFTER release
