We are all doomed by this virus.

My last tweet on this earth perhaps? (hat tip to @BogdanEnache)

During viral infection, in ATHLETES, CMR shows:

Myocardial EDEMA in 19% acutely, 24% at followup.
Myocardial INFLAMMATION in 38% acutely, 48% at followup.

Winter is coming.
Except ...

jcmr-online.biomedcentral.com/articles/10.11…
What proportion of athletes will get this virus?
9 out of the first 10 votes wrong.

I think it is almost 100%.

Clearly you haven't read the paper, you slackers!
Here is the deadly coronavirus that did this horrible thing to people's hearts.
Turns out that MRI evidence of oedema and of inflammation happens not only during the common cold (and followup), but also at baseline (BEFORE they caught the cold).
What do you think?

I have no idea how he finds these things. But I am sure glad he is not on the side of Covid Panickers, or we would be really screwed.

That's why frightening people with news stories is so harmful.

I can't say "no it is definitely wrong".

But only in the same way as I can't say "there is no Loch Thames monster".
Just because something is strictly speaking unknown and indeed *unknowable*, does not mean that it should be treated as having a 50 50 probability.

That is a recipe for going back to the dark ages.

"Or she may not be"

My advice for the general public?

DO NOT WORRY ABOUT HEART DAMAGE FROM COVID.

"If you as a member of the public are searching the internet for scientific data on heart damage, you are doing it wrong."

Uncle Darrel
J Condescending but True Facts
The reason why I recommend the general public not to worry about such things is that there is nothing useful you can do about the worry, other than just worry.

The whole point of having scientists to do science and doctors to explain it to you, is so that it is done well.
Scientists spend a lifetime learning how to examine experimental designs, results, and claims from the results; how to check track records of researchers; and how to integrate this into a useful view of the universe.

It is not easy and it is not quick.

Somehow I find myself cornered into being a world expert on everything.

(My daughter used to believe that. But that was when she was three after a remorseless campaign of me emphasising that point.)
In my simplistic view, Myocarditis is like a bruise.

If someone punches you in the arm, you will get a bruise, and it will eventually get better (unless you die from complications of a broken bone).
During the immediate few days after the punch-ment, there will be:

Raised CRP
Raised CK from the traumatised muscle
It will probably hurt a lot.

Then it will get better and go away.

This story is interesting:
Now that you are all scientific thinkers, I am sure you are all wondering:

Innocent looking chap, eh? Trustworthy?
Wouldn't con his poor doddery old boss?

"You know you said you would give me anything, if I could teach you Machine Learning?"

"Yes, and you did. What is your 1 wish?"

"22% pay increase."

"Done!"

--- and I certainly have been!

#FOAMED
He didn't fully emphasise that this was 22%, per year, FOREVER.

If his salary is $1000 a year at present, what will it be in 1 year's time?
And after the 20th increment, what will his salary be?

Oh

My

God

I _had_ given up annoying people, forever.

But this one is such a facepalm. And there is now online evidence of me completely failing to debug a numbers thing.

All blame goes to @mshunshin for my relapse.
I told Matt I had read this paper and I was gonna get some of this eicosapentanoic acid stuff for my TGs.

Then he said, "don't bother, just look at Table 2"
So I looked up the EVAPORATE paper again, and thought the master was merely swatting the grasshopper aside.

"Good try, Matt, but it will be OK - they have an 'out'"
