🚨 New PECARN Study Alert! 🚨
The PECARN STArT trial asked an important question: Could IV arginine help children and young adults with sickle cell disease recover faster from acute pain episodes?

🚨 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 👍.

"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…

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.

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.

Is the "LP for every febrile infant ≤28 days" dogma finally dead? 🪦
@JAMA_current pooled analysis of 2500+ infants ≤28 days old shows that the PECARN febrile infant rule missed ZERO cases of bacterial meningitis.

🏥 Same hospital.
🧠 Same stroke.
❌ Different treatment.
Black patients saw no or minimal gains in stroke treatment after certification, unlike White patients.
