🫁 Is the time to anticoagulation associated with mortality among patients with PE? Put your guess in the comments below! 💬 EMA has another PE paper to digest from the The Journal of Thrombosis and Hemostasis (JTH) this month. Timing is everything in treating a PE, right? Mortality matters, but did these authors get it right? Did they give us something we need to change our practice? 🎧 Tune into this FREE EMA chapter on the EM:RAP app to hear Mike and Sanjay dissect and analyze the paper and see if it’s a practice changer or not. 🤔 📖 PMID: 42315027 #pulmonaryembolism #MedEd #emergencymedicine #EBM #EMA #emrap #DOAC #anticoagulation

Finally, hematologists won’t be badgered to give EPO+Iron+Folate cocktails in desperately sinking JW acute bleeders. I welcome this development, but mourn the unnecessary loss of lives for those who died on this hill. jw.org/finder?wtlocale=E&doc…

The Surviving Sepsis Campaign has shaped sepsis care for decades. But do some of its core recommendations now lag behind the physiology and the evidence? Rory Spiegel @TheEMNerd led this new dissenting opinion, which I was very pleased to contribute to. We challenge: • fixed 30 mL/kg fluid loading • chasing lactate with fluid • fluid responsiveness as a sufficient reason to give fluid • pressure-centric resuscitation • the omission of POCUS from modern haemodynamic assessment • rigid bundle-driven care The argument is not for less treatment. It is for more individualised, physiology-driven treatment of shock. authors.elsevier.com/c/1npdk… The 2026 Surviving Sepsis Campaign Guidelines: The dissenting opinion Spiegel et al.

#Thiamine in the ICU: 10 high-yield pearls 1. Unexplained lactate? Think thiamine. Thiamine is required for pyruvate dehydrogenase. Deficiency blocks conversion of pyruvate to acetyl-CoA, shunting pyruvate toward lactate and impairing mitochondrial aerobic metabolism. Thus, thiamine deficiency belongs in the differential diagnosis for otherwise unexplained lactic acidosis. 2. Thiamine deficiency in the ICU is not rare. ~30-70% of critically ill patients are thiamine-deficient. Many arrive deficient; others develop deficiency during critical illness because of increased metabolic demand, inadequate intake, or losses. 3. The bedside phenotype is more important than waiting for a thiamine level. High-risk situations include malnutrition, alcohol-related liver disease, bariatric surgery, renal replacement therapy, polyuria/DKA, chronic diuretic therapy, unexplained encephalopathy, unexplained lactate elevation, and sepsis. 4. Starting nutrition can unmask the deficiency. Glucose administration increases carbohydrate metabolism and thiamine utilization. A malnourished patient may therefore develop rising lactate after initiation of enteral/parenteral nutrition. Refeeding syndrome is not simply a phosphorus/potassium problem; thiamine deficiency can be central to its pathophysiology. 5. Dialysis and polyuria are major clues. Thiamine can be lost during continuous RRT, hemodialysis, and peritoneal dialysis. Renal losses also rise with polyuria, including the diuretic phase of AKI, post-transplant polyuria, DKA, and chronic diuretic therapy in heart failure. 6. Do not wait for the classic Wernicke's triad. Altered mental status, ocular abnormalities, and gait ataxia are rarely all present together. I think I have seen it only a few times. In an at-risk ICU patient with otherwise unexplained encephalopathy, absence of the complete triad should not reassure you. 7. A plasma thiamine concentration is not a great “rule-out” test. Testing is often unavailable and expensive, and blood concentration does not necessarily reflect tissue thiamine status. I don't even remember when I last ordered the test (if ever...). Erythrocyte transketolase activity is physiologically more informative, but its cutoffs are poorly defined. Just recognize the risk population and consider a therapeutic trial rather than wait for laboratory confirmation. 8. The sepsis data are more nuanced than “thiamine works” or “thiamine doesn't work.” Thiamine is not expected to improve hard outcomes in the overall septic-shock population. Some subgroup analyses and meta-analyses suggest signals for improved lactate clearance and organ function, particularly renal outcomes. I don't consider it a magic drug... 9. Thiamine alone ≠ HAT (hydrocortisone + ascorbic acid +thiamine) therapy. Do not interpret negative trials of HAT as proof that correcting thiamine deficiency is useless. Large HAT RCTs failed to demonstrate the dramatic clinical benefit initially claimed, and a VICTAS secondary analysis raised concerns about longer-term outcomes. That is a different question from replacing thiamine in a patient likely to be deficient. 10. The kidney may be an important target organ. Renal tubular cells are highly energy dependent. Across secondary analyses, observational data, and meta-analytic evidence, thiamine supplementation -particularly in deficient patients- shows a signal toward less AKI progression, better renal recovery, and less need for RRT, although individual RCTs have not consistently demonstrated significant benefit in unselected populations. Rule of thumb: “⬆️ lactate + risk factor + no good explanation" → think B1 deficiency” Especially think about it when you see malnutrition/refeeding, alcoholism/cirrhosis, dialysis, polyuria/DKA, chronic diuretics, unexplained encephalopathy, sepsis, or otherwise unexplained persistent hyperlactatemia. I usually include it in the admission orders for most of my ICU patients along with DVT and GI prophylaxis...! Thiamine deficiency behaves less like an obscure vitamin deficiency and more like a potentially reversible form of mitochondrial energy failure. Or that's how I like to think about it. #foamed #foamcc #meded
