Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

NEW episode: Which studies presented at #ESCCongress showed practice-changing results in thrombosis management? Listen to @gbarnesmd.bsky.social and @mproiettimd.bsky.social discuss the updates you need to know on venous thromboembolism and atrial fibrillation #MedSky #ESC2025

Happy World Pharmacists Day! 💊

We celebrate the pharmacists who play a vital role in advancing safe, effective, and evidence-based anticoagulation care. From stewardship to education, research, & direct patient care, pharmacists are essential partners in improving outcomes for patients worldwide.

There are so many unanswered questions in acute PE management. Thankfully, we’re finally getting some RCTs to help answer them! #PERT2025

My patient recently lost his Medicaid insurance and couldn’t afford his meds.

Just calculated the cost of his 13 💊 which would be $2300/month. That’s around $27,500/year.

The FPL for a family of 4 is ~$32,000.

This is not sustainable for the health and lives of our patients!

I talked with a doctor in rural Wisconsin about what she wished elected officials in Washington understood about the health care system.

Her answer is important for every American to hear:

A new @thrombosiscan.bsky.social survey found that >50% of Canadian cancer patients have little or no awareness of cancer-associated thrombosis (CAT) — a major cause of death in cancer.

📊 Only 27% recalled being educated on CAT risks, yet most want more info!
