NLR needs to be interpreted in clinical context

look at NLR for the next thousand evals you do & it will start making sense

short version:

NLR 1-3: normal

NLR ~8-12: moderate stress (most ICU patients, eg DKA, CHF)

NLR >~20: yikes territory (sepsis?)

NLR >40: super yikes (Gram neg rods?)

New paper out! 🚀 This study presents a model combining B-mode ultrasound (BMUS) and CEUS for accurate prediction of the macrotrabecular-massive (MTM) subtype of HCC, and explores its potential to predict recurrence-free survival (RFS).

There’s now a “Google for doctors.” OpenEvidence is fast, eerily good, and sometimes confidently wrong — so still needs supervision. Here’s how it works, and how it compares to the existing 10,000 Pound Gorilla of Medical Information, UpToDate. #IDSky open.substack.com/pub/paulsaxm...
Yes, There's Now a Google for Doctors
How AI finally delivered on my colleague’s joke — and how it’s changing the way clinicians look up medical information.

It feels like there has been a sea change in studies on PRBC transfusion, with newer studies often tending to favor more liberal transfusion.

I wonder if this might relate to better modern management of volume overload, or improvements in transfusion safety over time? #EMIMCC
Three recent RCTs in acute brain injury show a consistent trend favouring liberal red cell transfusion, with fewer unfavourable neurological outcomes and less cerebral ischaemia or vasospasm than restrictive thresholds. zurl.co/rtzpF

A man in his 80s visits the ED because of epigastrialgia. The resident sends him home with a diagnosis of gastritis (even though CRP was 30). Comes back 2 days later, CRP now 250. Diagnosis was not hard at that point. #POCUS #EMIMCC

This is something I say a lot too. People (not the author) seem to think the only thing doctors do is diagnose. In reality, that's a tiny part of a modern doctor's job in the real world. A fancy AI offering diagnostic powers would help me only quite occasionally. Real life is not like House.

Sent to the ED by PCP for fever and “left lower lobe consolidation”. Was still waiting for chest X-Ray.

DKA Tip #2: Urine dip can mislead
-Body produces 3 ketones: acetoacetate, acetone + beta hydroxybutarate (BHB0
-UA only looks for acetoacetate. BHB dominates in early in DKA
-If worried about DKA, get a chem/blood gas for bicarb + pH + serum BHB

antibiotic stewardship pearl:

Pneumonia patient on ampicillin-sulbactam

Blood grows Strep pneumo, sensitivity pending

Patient is improving

Sulbactam adds *nothing* to ampicillin for S. pneumo (resistance not mediated by beta-lactamase)

So you can immediately narrow to ampicillin #IDsky #EMIMCC

if you’re getting a CT chest for a critically ill patient in respiratory failure of unclear etiology, it should be a CT angio to evaluate for PE (& other stuff)

sometimes being thorough is more effective than being smart

also, contrast allows evauation of cardiac chamber size & IVC reflux
