We hope you enjoyed our case files this week! This patient ended up having anti-synthetase syndrome. In inflammatory myopathies, the antibody profile can help you predict the associated findings.

4. Check one-time cystatin C in sarcopenia (plus frailty, amputation, rhabdo) for better GFR estimation for medication dosing safety But, cystatin C isn't always right, particularly with steroids, obesity, acute inflammation

Being obsessed with happiness can make us unhappy. Joy doesn't arise from ruminating about our emotions. It comes from immersing ourselves in worthwhile experiences. Happiness is not a goal to pursue. It's a byproduct of leading a life of meaning and engagement. Trevor Noah

Updates to Pancytopenia inspired by Lukas Ronner heme conference. Stole parts of it from the amazing William Aird and The Blood Project Biggest takeaway: most important test is the "Vibes" test (i.e., take a good history and exam and let that guide workup). Erin Aakhus

🙏🏻 Labeling a true “UTI” as a “UTI” is also dangerous. We must be more precise and label the syndrome as cystitis, pyelo, prostatitis, etc. Way too often a fever+pyuria is labeled as a “UTI” & we are missing pyelo, perinephric abscess, GNR bacteremia or another cause of fever!
