You win tonight's box of chocolates for most information provided.
Erm, I don't have your address and besides, the postage costs more than
the pralines themselves, so the box might be minus the chocs.
That aside, there's the matter of what is or is not off topic.

1) Does the BMJ publication not come under the term Media?

I wrote on the assumption it did.

2) Is it only valid (on topic) to refer to something currently in the
media (were "currently" has a decent retro-lifespan) and therby
disallowed to mention something that perhaps should be, though opinion
on "should" may be problematic?

Have a nice few days off (-:
