Yes! Vax booster mandates are just like seat belts. In 3 months in 1984, for anyone who didn't buckle up 100%, they were fired from their place of employment and not allowed to work again in that sector. Enforcement was absolute...
Also people who had seat belts already (natural immunity) That didn't count. You had to install the special new seat belt. And you only had a few months to do it.
Oh, and we initially believed that seat belts would protect other people. But then very quickly we learned that there was a new variant and they only protect the wearer, but that didn't stop us.
Oh and seat belts worked super well in older people. So much so they should wear three. But it wasn't clear that younger people, particularly men, needed three seat belts, but we fired them anyway for not complying.
And the seat belt company announced that you would probably need a new additional seat belt every year forever. And we wouldn't do a randomized trial based on survival after an accident to prove it, but non-inferior coverage of your torso with belt.
Oh, and if you always wore your seatbelt, and install seat belts for others, and recommended seatbelts, but felt we shouldn't fire people for not wearing seatbelts. You were an anti seatbelter.

Everything in this thread is incorrect. Literally every recommendation. Here's a thread why. 1/7
There's not a single randomized controlled trial that shows people who undergo a coronary artery calcium test live longer than those who do not undergo it. Everyone will benefit from increasing exercise and eating better and the score is irrelevant
Maybe the only cancer screening test that has any utility under 35 is the pap smear. Mammography doesn't improve survival at any age, and has no data in this age group. Totally crazy recommendation

Glad that we @vkprasadlab have published over 20++ peer reviewed papers on COVID19 policy to date & many more to come

I will share them here & a free link to all of them at end

We see policy failure

#1 visitor restriction
It was sad to separate family from dying people, & had no dataImage
Cloth masking 2 year olds was an unforced error by @cdcgov and @AmerAcadPeds, who pushed this policy with no credible data, and despite its obvious silliness Image
Long COVID is an evidence based disaster
There is a strong narrative that is not well supported by the evidence.

To date, besides anosmia, there is no evidence COVID has any more long symptoms than being equally ill with any other respiratory virus. period. Image

A new 22 page essay by Mariana Barosa, @ID_ethics and me!

"We argue that high-quality research, namely by means of well-designed randomized trials, is ethically obligatory before, during, and after implementing policies in public health emergencies"

Our essay reimagines the status quo. Instead of implementing and deimplementing and never knowing the answer, Public health must work to reduce uncertainty.

Shown nicely in Figure 2 Image
We discuss many Non pharmacologic interventions tried and their limited evidence

This table represents an evidence based disaster. Nearly none of these were tested with proper trials
Forget beach closures and taking the swings out of parks Image

When I read an #ASH23 abstract that asks whether PFS or MRD is a surrogate endpoint in FL (L) or CLL (R), I know instantly the person on the left did it right and the person on the right messed up

Want to learn how?
& diff btw
Prognostic, predictive & surrogate
#Tweetorial Image
When it comes to biomarkers there are 3 categories
Prognostic
Predictive &
Surrogate
#ASH23

A prognostic marker means that the marker is associated with a better or worse prognosis in a cohort of patients

For, e.g. HER2 is a poor prognostic feature in metastatic breast cancer

& in this CLL analysis
Having MRD is bad! (unsurprising)

Small cell lung cancer is a horrible diagnosis, and I feel sadness for anyone who has it

A double lung transplant for small cell lung cancer is complete nonsense. @VUMChealth is just making things up. This story is so sad bc doctors want to practice on the island of Dr Moreau

We discuss evidence for STARTING & STOPPING cancer drugs!
What do I mean?
Currently in cancer med, we ~always start treatment at first sign of metastatic disease, and stop at progression, but....

... does this make sense?
The table shows trials testing early starting vs. delayed starting of systemic Rx.
For many diseases, there is no advantage to treating even widespread, asymptomatic disease
For most disease, however, there is no study at all!!
We truly don't know Image
But generally we assume. In many tumor types, we treat even asx or mildly symptomatic metastatic diseases (denovo or recurrent)

Now, lets consider the flip side of the coin. When should we stop treatment....
