I am on the job market and wanted to advertise myself here! 🤠 Looking for full-time or contracting roles! Historically, my work spans population dynamics, healthcare informatics, robust adaptive controls, software engineering, and community engagement. 🧪 #STEMjobs #academicsky #publichealth

I don't understand the relationship between CO and ETCO2. ETCO2 increases with rising CO, if ventilation and CO2 production is constant. Is this just temporary? We can't exhale more CO2 than we produce. #anSky #medSky @doctorhelgi.bsky.social @load-dependent.bsky.social @jm-l.bsky.social

There's a puzzle I've found annoying so I thought I'd let you find it annoying too: kucharski.substack.com/p/why-the-tu...

Thanks for the reminder @janemunday.bsky.social. Every summer, I repost this article DROWNING DOES NOT LOOK LIKE DROWNING. To date, I know of FOUR kids who were saved after someone who'd clicked on the link learnt how to spot actual drowning. Take time to read and pass on. slate.com/technology/2...

Absolutely fascinating! We know the heart switches to lactate as energy substrate in shock, could there be a clinical benefit from lactate infusion in human cardiogenic shock? #emimcc #cccsky

My cardiac arrhythmia simulation now also simulates how a reentrant loop can be terminated by increasing refractory time as suggested by @empoisonpharmd.bsky.social Direct link to the updated part: jenevoldsen.com/posts/excita...

✨ It's new samwho visual essay o'clock! ✨ Reservoir sampling is one of my favourite algorithms. It allows you to sample from a set without knowing the size of that set. I try to assume no prior knowledge, and use no scary math notation. Just beautiful visuals. Let me know what you think! ❤️

I just want to say I use this constantly at the bedside when dealing with patients who have arrythmias to explain how they propagate. would LOVE LOVE a model where increasing refractory terminates reentrant rhythm so I can show how diltiazem terminates SVT. such an amazing tool, thank you

Where I could really see a place for LLMs in medicine right now, is not for decision-making, but for understanding a patient's medical records in a reasonable time. - Find plans for this admission, that were never followed up upon. - Give a short review of the pt's medical history. ...

The Hypotension-Prediction Index--a convoluted way of predicting hypotension by...checking whether the MAP is low--fails once again. Shocker. "HPI-guided hemodynamic therapy did not reduce the incidence of postoperative AKI or overall complications [vs] standard care."

I wrote a short interactive article👆 It uses simulations to demonstrate how different cardiac arrhythmias can develop. Try it out! (It has defibrillators ⚡️) jenevoldsen.com/posts/excitable-cells #medsky #cardiosky #cccsky #emimcc

Is it possible to have massive pulmonary emboli, get systemic thrombolysis and then have no thrombus visible on a CTA a couple of hours later? Was there ever pulmonary emboli? #emimcc #cccsky

It’s mostly nonsense anyways Wait for the trials to come out www.nephjc.com/news/landmar... ajkdblog.org/2021/06/16/c...

I recently had an equivalent experience with understanding calcium-phosphate disorder in CKD... 🫠

What do we think about adjusting p-values for safety outcomes for multiple testing, and then claiming no significant harm? Is this common practice? Any papers commenting on the (in)appropriateness? #statsSky @stephensenn.bsky.social @statsepi.bsky.social @f2harrell.bsky.social

Which is why we need people who critically look at ML/chatgpt/AI I love new toys, gadgets, technology, data trends But I’m a scientist first and hope this will never change

This is something I've had to rediscover every time I've made graphics for a new project. Great post.

Semi related - we went big on the pivotal like protocol in Ottawa www.nephjc.com/news/pivotal Our ESA requirements plummeted. Many patients have come off ESA completely. I think that’s a good thing!

#askrenal A patient on hemodialysis and EPO has a hemoglobin of 9 mmol/l (14.5 g/dl). Do you phlebotomize (e.g. dumb dialysis blood) or just reduce EPO? (Is it the Hgb itself or the overtreatment with EPO that increases mortality?)

I like how rigors are strongly predictive of bacteremia but a "feelin' a little chilly" has a LR < 1 (though not significant). (From JAMA RCE Does This Patient Have Bacteremia). #MedSky #IDsky

point-of-care electrolyte analyzers cannot detect hemolysis! so point-of-care hyperkalemia may or may not be real. in this case, the hyperkalemia was wholly artifactual. think twice before unleashing therapy for hyperkalemia (the ECG is often the key) (more: emcrit.org/ibcc/hyperka...) #emimcc

Any recommended resources for learning #POCUS ? And are there any especially high-yield examinations to start with? #nephsky #medsky

The central venous pressure (CVP) waveform is the interaction between a fast cyclic effect of the heart and a slower cyclic effect of ventilation. A steady CVP waveform can be visualized as a 3D plane. 🩺 (Old Twitter post)

Had a patient who, when I entered the room, paused the music playing on his bluetooth hearing aid. He then asked me to excuse him until an ad had finished, before he could hear anything. Probably a user error, but felt quite dystopian 😨

The following question was posted on a different platform: Can you comment on diastolic function in a patient who is not at steady state (eg anaesthetised, critically unwell on inotropes)? Here are my thoughts (and my strongest pet peeves- leading to my handle) #echosky 📟 #cardiosky

I would like to report a near miss event please

I am currently planning on writing a whole research paper in #quarto/ #r-#markdown. How do other fellow #academic researchers enable others (possibly without #git/ markdown) to provide comments that are easily integrated in a markdown flow? #AcademicSky #StatsSky #EconSky

Are trends really that useful? 📉 I see a lot of doctors emphasize the importance of looking at trends (changes) in measurement, e.g. lab values or vitals. Can anyone give examples where trends give important info over simply looking at the most recent value?

Put another way, I've come across very very few applications of AI in medicine and health that might actually be worth "explaining"! 😜
