Ask not why would you work in biology, but rather: why wouldn't you? https://t.co/7zkdjniFQ9 openai/gemini gave this essay an A- for evocative imagery. claude gave it a C- for being emotionally manipulative. both are probably right. i feel a little sick re-reading it

A recent study, led by Catherine Gao, PhD (@CatGaoHow), explores how machine learning models like LSTM and XGBoost can analyze electronic health record data to forecast next-day extubation with high accuracy. The findings suggest machine learning could support, not replace,

@alecpeltekian @CatGaoHow @NUFeinbergMed š Next steps are to explore how to integrate this model into clinical workflows and evaluate its impact prospectively. Weāre also interested in expanding to other ICU populations and incorporating additional data streams like imaging and clinician notes!

@alecpeltekian @CatGaoHow @NUFeinbergMed In failed extubation cases, the model wouldāve advised against extubation 35% of the time, showing promise as a second opinion tool š”. Top predictors from SHAP and ablation testing include plateau pressure, heart rate, PaCO2, aligning with clinical intuition.

@alecpeltekian @CatGaoHow @NUFeinbergMed Our best model, an LSTM š¤ , predicted next-day extubation with AUROC 0.87 in both our internal and external validation hospitals. It often flagged patients as ready for extubation days before it actually happened, suggesting potential to wean earlier.

@alecpeltekian @CatGaoHow @NUFeinbergMed We built ML models to predict ICU patientsā readiness for extubation, a decision thatās critical and time-sensitive. Too early = failure. Too late = complications.

@alecpeltekian @CatGaoHow @NUFeinbergMed We trained models on 37 clinical features (vitals, labs, meds, vent settings)š« collected from midnightā8 AM ā° , so predictions are ready for morning rounds. We carefully annotated data, reviewing hundreds of charts.

A new gene-editing therapy may have cured a baby of a deadly metabolic disorder. By inserting a corrective gene into a 'safe harbor' of the genome, this approach aims to avoid the risks of traditional gene therapies.

Result could be first success at stitching a curative gene into a chromosomeās āsafe harbor,ā reducing cancer and other risks

This has promise to change surgery. We havenāt had a new class of painkillers for acute pain for decades. And 15,000 people died of prescription opioid overdoses in 2022. But will be interested in hearing from anyone with real world experience.

The drug could become an alternative to the opioids that stoked an epidemic of dependency and overdoses.

Itās crazy how talking with a science buddy is simultaneously whatās most likely to move the project forward and the thing thatās least prioritized in our schedule.
