New influenza vaccine w mRNA in @nejm.org which is great (look at the Kaplan-meier curve in cover fig).
For #dermatology, we have seen non-clinically-significant arm redness in other recent mRNA vacccines - true here too. As w covid mRNA vaccine, seems mild & can generally reassure/monitor #DermSky

Since everything is depressing, but this pic / case was great for #DermSky (thank you @iuidfellowship.bsky.social), I’ll add that dolphins can get lobo too

Also, the climate impact / reduced CO2 emissions of virtual interviews are one important reason I hope they continue (plus having student fly crisscrossing the country & sitting w tons of doctors in the height of winter flu / virus season is medically suboptimal)

See our pub on emissions impact:

I am fairly sure the influx of new followers is thanks to @katharinehayhoe.com & her starter pack on climate & health-

Please see our paper out today in @jama.com, a comprehensive carbon footprint analysis of an outpatient academic medical clinic:

Nice pic of granulomatous cheilitis in @jama.dermatology (not yet a Bluesky account, but @jama.com should start bringing specialty journals here!):

This is a growing issue here in the US as well

(Nice example pic from former @pennmedicine.bsky.social #Dermsky resident Avrom Caplan, who has done a ton of work identifying and highlighting this issue, here in @nejm.org):
