🎉 Congratulations to Dr. @RodgerMarc and the entire team on their @isth oral presentation! 👏 🤰 An unlikely LEFt score + negative D-dimer safely excluded suspected #DVT in pregnancy without ultrasound. 📊 No VTE events occurred in this low-risk group, while a likely LEFt score identified patients at high risk (≈28% VTE), supporting prompt imaging and close follow-up. An important step toward safer, evidence-based care for pregnant patients. 👏🔬 #ISTH2026

Congratulations to Prof @isabellemahe1 and the #APICAT investigators! Presented today as an oral presentation at #ISTH2026 in Paris, with simultaneous publication in @CircAHA. ahajournals.org/doi/10.1161/… Key findings: ✅ Recurrent VTE during extended apixaban was uncommon (2.5%) ✅ Recurrence varied by cancer type ✅ Index VTE predicted the type of recurrence (PE→PE, DVT→DVT) ✅ Despite being rare, recurrent VTE carried a 50% early mortality @ISTH @INNOVTE1 #ISTH2026

Statement by Becca Good. Read it @JDVance—and burn in hell. “First, I want to extend my gratitude to all the people who have reached out from across the country and around the world to support our family. This kindness of strangers is the most fitting tribute because if you ever encountered my wife, Renee Nicole Macklin Good, you know that above all else, she was kind. In fact, kindness radiated out of her. Renee sparkled. She literally sparkled. I mean, she didn’t wear glitter but I swear she had sparkles coming out of her pores. All the time. You might think it was just my love talking but her family said the same thing. Renee was made of sunshine. Renee lived by an overarching belief: there is kindness in the world and we need to do everything we can to find it where it resides and nurture it where it needs to grow. Renee was a Christian who knew that all religions teach the same essential truth: we are here to love each other, care for each other, and keep each other safe and whole. Like people have done across place and time, we moved to make a better life for ourselves. We chose Minnesota to make our home. Our whole extended road trip here, we held hands in the car while our son drew all over the windows to pass the time and the miles. What we found when we got here was a vibrant and welcoming community, we made friends and spread joy. And while any place we were together was home, there was a strong shared sense here in Minneapolis that we were looking out for each other. Here, I had finally found peace and safe harbor. That has been taken from me forever. We were raising our son to believe that no matter where you come from or what you look like, all of us deserve compassion and kindness. Renee lived this belief every day. She is pure love. She is pure joy. She is pure sunshine. On Wednesday, January 7th, we stopped to support our neighbors. We had whistles. They had guns. Renee leaves behind three extraordinary children; the youngest is just six years old and already lost his father. I am now left to raise our son and to continue teaching him, as Renee believed, that there are people building a better world for him. That the people who did this had fear and anger in their hearts, and we need to show them a better way. We thank you for the privacy you are granting our family as we grieve. We thank you for ensuring that Renee’s legacy is one of kindness and love. We honor her memory by living her values: rejecting hate and choosing compassion, turning away from fear and pursuing peace, refusing division and knowing we must come together to build a world where we all come home safe to the people we love.”

François Legault a imposé une loi spéciale sous bâillon dans la nuit de vendredi à samedi. Avec sa loi sournoise, François Legault instaure la police des médecins. Dans chaque cabinet médical, un « stool » doit être désigné pour dénoncer ses propres collègues aux enquêteurs, qui eux se rapportent au niveau inspecteur national du « stool ». ⚠️AVERTISSEMENT: ceci n’est pas une blague, je suis sérieuse. Bienvenue au CAQistan, état de délation! Pire, quiconque encourage les médecins s’expose à de sévères pénalités ! La liberté d’expression ? Non, pas au CAQistan! Legault instaure le délit d’opinion avec sa loi matraque. Qui seront les prochains ? Les policiers ? Les infirmières? Les inhalothérapeutes ? 🚩 Cette loi spéciale est liberticide et va trop loin. #DehorsLaCaq

🧠 Diagnosing recurrent VTE is challenging. PREDICTORS study (n=723) showed that existing clinical decision rules (CDRs) identify patients at higher risk and RO recurrence without imaging in ~15% 📊 In low/moderate-risk PE with negative D-dimer: 🟢 0/82 recurrent VTE (0%; 95% CI 0.0–4.4) CDRs help but caution is warranted. 📄sciencedirect.com/science/ar…

🚨 SPECTACULAR RCT at #ISTH2025! Although non-inferiority to CTPA wasn’t shown, a negative SPECT V/Q scan led to low 3-month VTE risk ✅ Supporting the safety of ruling out PE with a SPECT-based algorithm SPECTacular findings indeed! 🫁💥

Is this the end of rivaroxaban for acute VTE? @LanaCastellucci presenting the COBBRA trial - 1st RCT comparing apixaban to riva over 3 months. 56% reduction in bleeding risk with apixaban. A safer Rx with the same efficacy. #ISTH2025

Hot off the press! COBBRA trial showed that apixaban is associated with >50% reduced risk of clinically-relevant bleeding symptoms for acute VTE treatment. This can be practice changing! @LanaCastellucci @RodgerMarc @canvector
