The Sequential Organ Failure Assessment (SOFA) score is the most widely used tool for evaluating organ dysfunction.
This week, JAMA published the SOFA-2 score, an update that incorporates current organ support therapies and introduces new scoring thresholds.

Five years ago today, most historical UK monthly rainfall observations were not available to scientists.
But the 66,000 pieces of paper containing the data had been scanned.
With covid lockdown approaching we saw an opportunity to transcribe the data.

Agree.
All the physiological variables that contribute to shock are continuous. Need to move beyond categorisation.

ICU Hemodynamics:
We divide patients with circulatory shock into 3 primary hemodynamic phenotypes, namely hypovolemic, vasodilatory/distributive, & cardiogenic (including obstructive)
But we all witness/manage "mixed" shock, an entity lacking a uniform, evidence-based definition:

This was a fun study leveraging social media to demonstrate the high prevalence in Impella malrotation among cases shared on old Twitter.
If it's malrotated, but it works well, without suction alarms or other problems, do you change it? #cccsky #cardiosky #emimcc
