There’s this idea that a false positive means screening is not working; it’s part of why health systems argue against screening at all.

See fights over: mammography, serum PSA, Lung cancer screening, colonoscopy, etc.

I wouldn’t say most frontline doctors are personally against screening, but they hate fighting with insurance companies over this stuff, and would rather not deal with it.

I can speak from the radiology perspective:

My problem with Prenuvo is not the screening aspect; it’s that Prenuvo is poor value. For the cost you pay out of pocket, I can find you conventional imaging centers that will charge the same (or less!) for fully diagnostic images and a fully diagnostic report. And they will give you the images on disk (or a link to a portal) right there.

If you want to be screened and have the cash to pay for it, go right ahead! Knowledge (can be) power! With the caveat that imaging is step 1 and you may need further work up. Don’t go to the Theranos of imaging; go some place truly diagnostic.

Which party was in power when 2008 happened?

This data is from 2006. Over 20 years, there has been substantial progress in CT radiation reduction through model-based iterative reconstruction and now ML-assisted reconstruction, aside from iterative advances in detector sensitivity and now photon-counting CT.

In clinical practice, those doses are about 2-3x what I see on the machine dose reports every day at my place of work.

In thin patients who can hold still, I've done full-cycle cardiac CT and achieved a < 1 mSv dose. We are always trying to get the dose down while still being diagnostic.

I had no shop class in my middle school years 99-2002 but technical theater is the closest thing that may still sneakily exist in many schools. I learned basic carpentry and electrical, including lighting design and sound, all in the service of making sets for the yearly plays.

RE horizontal - there is a ribbon cable that can literally fracture which causes the Zr and Zl buttons to quit working which only really manifests when trying to use 1 joycon horizontally (personally when Mario party happens).

The repair takes about 20 minutes the first time you do it and the ribbon cable is on amazon for about $7.

Strictly speaking, phenylphrine works when it’s injected. It is approved and used every day for this indication in the service of general anesthesia.

However, the oral bioavailability is zero.

This is an example of using something off label that’s approved for something else. Sometimes it’s fine. And sometimes, it’s dumb.

Nit: isn’t “playing” itself “nouning the verb” via a gerund / participle construct?

I actually am not sure of the subtleties on this grammatical point.

This sounds like they are somehow identifying the user and querying theworknumber.

You can get a ton from a worknumber query.
