3/ Then came the LLMs 🤖✨ GPT-4o, GPT-4o mini, Llama 3.1 🦙, Mixtral-8x7B. Clear winner: LLMs by far 🚀

To validate externally, we labeled MIMIC notes 📚 and published theses annotations so others can build on this: 🔗 physionet.org/content/immu...

Paper code: github.com/NUSCRIPT/gug...

Immunosuppressive Condition and Medication Annotations for Admission Notes in the MIMIC-III Database v1.0.0

This database contains 200 MIMIC-III admission notes with adjudicated labels for histories of various immunosuppressive conditions and usage of various immunosuppressive medications.

2/ Most studies lean on structured data (ICD codes 📊) to capture comorbidities. We tested 10 thresholds → decent performance, but not perfect.

Next: classic NLP 📝 6 bag-of-words classifiers (NB, lasso, ridge, decision tree 🌳, random forest 🌲, SVM). Results? Also not bad!

1/ What started as a “hey, wouldn’t it be cool…” 💡 side project turned into a full study on how to identify immunocompromised patients.
Gold standard = research coordinators manually labeling statuses ✅ Everything else tested against that. 🔗 academic.oup.com/jamia/advanc...

Some important findings in this paper:
1) Working with AI boosts the performance of people solving math, science & ethics questions
2) The biggest boost is for the hardest problems
3) High performers remain highest performing, but low performers gain more
4) People who are good with AI gain most

Awesome work from @vijeethg.bsky.social - LLMs for the win! Hopefully this is one step towards doing less chart review. #LLMs #GPT @iaim-nu.bsky.social @nufeinbergmed.bsky.social @nuintmed.bsky.social #HBMI #HSIP

We hope it helps fellows as they begin their own searches.🌱 Grateful to Emily, Matthew, Pat, @nick-ingraham.bsky.social Clara, Nandita, and everyone who helped take and share the survey! <3 #earlycareer #PCCM

We found striking variability: clinician-educators 👩‍🏫 often received larger offers than physician-scientists 🔬, and both non-clinical FTE ⏱️ and startup packages 💼 were all over the map.

During my own job search, I was struck by how wildly academic offers vary—from $0 startup 😬 to multi-million-dollar packages 💰. Inspired by online datasets (ex: www.reddit.com/r/AskAcademi...), we surveyed PCCM physicians about their offers 📊.

Claude's new ability to work with Excel is the best I have seen so far

I have given it existing spreadsheets to work with and asked it to create new ones. Good use of formatting, formulas, etc.

It created all of this, including 406 formulas, from one prompt (& it would be solid work from my MBAs).

2/ 📊 German study 6,748 patients with CAP; 4,060 eosinopenic and 2,688 non-eosinopenic:
☠️ Mortality: 13.8% vs 9.1%

💨 Ventilation: 19.2% vs 14.3%

🦠 Sepsis: 7.5% vs 5.0%

🏥 Longer stays: 8.4 vs 7.6 days

1/ Something I don’t often look at in CAP patients, but might start to based on this paper: eosinopenia (eosinophils ≤50/μL), which has already been tied to poor outcomes in COPD & COVID-19.

369 ETTs cut and measured degree of blockage (see pic)
