It doesn't matter that experts say one thing on a hundred sites if a million sites written by ignorant people exist to counteract it.
You're not "asking an AI to answer a question" you're "giving an LLM a prompt and it is generating plausible text".

While we officially starting using the phrase "team-based anesthesia care" in spring 2025, the concept has over two decades of real-world practice behind it. Learn more about this history via our latest latest blog post, featuring our vice-chair, Dr. Sylvie Aucoin: https://ow.ly/fP4n50Xx51n

A sad day for cyclists. Bill 60 - which prohibits the conversion of motor vehicle lanes to bike lanes (or any other prescribed purpose) - has passed Third Reading this morning which will kill various cycling projects in Toronto & across Ontario. #shame #BikeTO #BikeSky #TOpoli #ONpoli #VisionZero

If you want to live in low-density, single-family neighbourhoods you should pay for it.
WATCH: If you STILL don’t understand how car-dependent suburbia is HEAVILY SUBSIDIZED by downtown & all the urban parts of your city, watch this EXCELLENT video by @notjustbikes with @UrbanThree & @StrongTowns. And then please SHARE it as much as possible. youtu.be/7Nw6qyyrTeI

I’m saddened to post the passing of Dr Earl Wynands on 2025-11-14 at the age of 95.
A pioneer of cardiac anesthesia, former chair of uOttawa Anesthesia, and the kindest soul you’d care to meet. He’ll be deeply missed.

This is interesting — a recent study of mode share (the % share of transportation trips by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social

Works for medicine too.
Coaching is not about prescribing and dictating.

It's about creating situations where the athlete is challenged to figure it out. You nudge them along, but if you always give them the answer, you aren't actually teaching. And they aren't learning.

My grandmother was a patient in a Halifax hospital when the Imo and Mont Blanc collided. The Christmas tree reminds of her and the kindness of neighbours.
boston sent vital assistance following the 1917 halifax harbor explosion (so awful it killed 1700 people), and as thanks, nova scotia has sent us a christmas tree every year. it’s a nice little tradition. this is the first time the boston mayor visited to retrieve it in person
In Canada, Wu helps chop down Boston's Christmas tree
Mayor Michelle Wu spent three days in Nova Scotia, saying she wanted to affirm Boston's relationship with Canada amid antagonism from the Trump administration.

Much needed.
Chapeau to the authors.
Airway management research has historically incorporated heterogeneous outcome selection and definitions. This impedes evidence synthesis and hinders advances in patient care.

So - here is a core outcome set to standardise airway management research!

The chance of having an allergic reaction to a neuromuscular blocking drug is:
• suxamethonium: ~1 in 1500 people
• rocuronium: ~1 in 3300 people
• atracurium: ~1 in 15,000 people

Women were up to eight times more likely to have a reaction than men.

We’ve lost our measles-elimination status.
#Measles, a highly contagious viral disease, is a leading cause of morbidity and mortality worldwide, particularly in regions with low immunization coverage.

“If anaesthetists are to adopt a screening test for an otherwise asymptomatic population, we must be reasonably confident that: the test detects the target condition; detection changes management in a way that improves patient-centred outcomes; and harms are outweighed by benefits”
Routine pre-operative modified telephone interview for cognitive status screening: feasible, but is it justified?
