I've been asked about this paper (www.nature.com/articles/s41...) enough times that I finally had to read it. The basic claim is that mRNA vaccines had huge synergistic benefit with checkpoint blockade against lung cancer melanoma. tl;dr it's glam-slop & everyone involved should be embarrassed

Due to the freeze on credit card use, my laboratory (in the FDA) risks losing the contents of our liquid nitrogen tanks which store INVALUABLE samples-they cannot be replaced, so they are literally priceless, and reflect about 50 years worth of research.

Philip Haywood discussed the pitfalls of cost consequence studies in virtual care. What is the value of freed up resources? #HSR24
Speaker next to a projected slide

The Pitfalls
Funding issues potentially problematic
Value based care not incentivised
Fall between State and Commonwealth responsibilities
Opportunity cost in developing models
Sufficient volume is required
Benefits may not occur within a year - capacity increasing
Possibility of choosing options that do not benefit society the most
A greater emphasis on the value of freed up resources is required - what do they mean?
Did not appear to support a reduction in expenditure but rather an increase in capacity
There are choices to be made - what are the "best" things to be doing?

I’ve been a doctor for more than 20 years & this is the first time that I’ve seen a paediatric stroke awareness campaign (from the American Heart Association). Gosh, what could possibly have changed in the past 5 years* which is increasing the risk of paediatric stroke? *Spoiler alert: it’s COVID
WHAT TO KNOW:
Face drooping, Arm weakness or
Speech difficulty means its
Time to call 911.
Be aware of other symptoms, including seizure, headache, vertigo or dizziness.
But strokes happen to children, too.

Whenever I write about long-covid or ME, I get waves of emails from chronically ill folk who say they feel seen and heard. But with this piece on fatigue (and PEM), I'm *also* hearing from healthy people saying that they finally get what their loved ones are going through. Which feels amazing.
