🚨 New @NEJM landmark trial from @PECARNteam: PRoMPT BOLUS randomized 9,000 children with suspected septic shock to balanced crystalloid vs 0.9% saline. No difference in kidney injury, mortality, or safety. Either is 👍. 📄 doi.org/10.1056/NEJMoa260196… 🩺 aliem.com/prompt-bolus-pedia…

"The jury is still out for treatment with arginine therapy." — Dr. @claudiarmorris1 The #PECARN STArT trial — a double-blind RCT testing IV arginine for sickle cell pain crises in children and young adults — was stopped early after an interim analysis suggested the primary endpoint was unlikely to be met. But Dr. Morris isn't ready to close the book on the drug. Here's why 👇 🔗 hcplive.com/view/pecarn-star… #SPARC #PECARN #PediatricEmergencyMedicine #EmergencyMedicine #SickleCell

PECARN STArT Fails to Improve Time-to-Crisis Resolution in SCD Pain, With Claudia Morris, MD |...

#NewBlogPost Most sepsis screening tools identify kids who already have sepsis, or who are already suspected of infection. That's useful — but it's not early enough. This @PECARN model predicts who will develop sepsis in the next 48 hours, across the general ED population, before clinical suspicion even forms. Earlier signal ➡️ earlier intervention ➡️ better outcomes. The biology hasn't changed. The tooling has. @JBelferMD @ERAlpernMD @FranBalamuth pecarn.org/pecarn_news/one-s… #PRIME #PEMNEWS #PediatricEmergencyMedicine #Pediatric #EmergencyMedicine #SEPSIS

One Step Ahead: Can AI Predict Pediatric Sepsis?

Sepsis kills children. It is a leading cause of pediatric death, with an in-hospital mortality of 5-20% in the United States [1, 2]. Early recognition and treatment improve outcomes, but predicting...

Same disease. Same pain crisis. Same type of hospital. One child goes home in 28 hours. Another stays nearly 6 days. A new secondary analysis from the #PECARN STArT trial — the largest pediatric sickle cell pain crisis trial enrollment to date — found that *where* a child receives care may matter as much as *how sick they are*. The findings are worth a close read. 🔗 pecarn.org/pecarn_news/same-… #SPARC #PediatricEmergencyMedicine #Pediatric #SickleCell

For years I built one-off, simple, no-code tools that worked but at a cost— jerry-rigged spreadsheets, screenshot-filled instruction manuals, workarounds I'd forget in 3 months. The missing piece wasn't another app. It was memory. 🧠 michellelinmd.com/blog/2026-…

Memory is the Missing Thread

I spent years building one-off tools that unraveled quickly. I then discovered the thread that could stitch them all together - me and my memories.
