I'm a doctor training in anaesthesia. The idea with epidurals is to introduce local anaesthetic outside the compartment where the spinal cord is, literally epi-- --durally.

To sample the CSF, or to give a spinal anaesthetic, the needle needs to be introduced into the subarachnoid (one of the membranes that surrounds the central nervous system) space, but at a level below where the spinal cord has terminated. This is why they're done in the lower back typically.

Bending over is a totally legitimate way to perform them, and doesn't really alter the complication rate, while making the procedure easier. Also, there isn't really any realistic option to perform them in real time with imaging guidance. The author is right in that larger cutting needles are associated with increased rates of PDPH.

I was thinking the exact same thing last month[1]! It's really interesting what the implications of this might be, and how valuable human-derived content might become. There's still this idea of model collapse, whereby the output of LLMs trained repeatedly on artificial content descends into what we think is gibberish, so however realistic ChatGPT appears, there are still significant differences between its writing and ours.

Does this matter to them though? Does apple care about having the dominant messaging platform if it's no longer a hook to get people to buy apple devices.

Describing it as a best kept secret seems unnecessarily adversarial. The medical community aren't jealously guarding treatments from the populace.

Arguably shock wave lithotripsy, a common method for breaking up kidney stones, could be described as focused ultrasound.

It's not as simple as you're suggesting. Take cancer screening for example. Doing more investigations and more procedures for things that weren't going to become problematic puts people at risk for the complications of those procedures.

Screening programmes need to be carefully thought out, not only from a cost-benefit, but from an actual risks vs benefits perspective.

Fantastic project. Amazing to think that there's an entire first century library just waiting for the technology to be read.

I have an interest in medical books from the first half of the 20th Century. It's fascinating what you can find, even in books that have been passed through many sets of hands.

In one, I found a stockbrocker's letter and managed to trace the owner to his historic pubmed articles (all > 100 years old), as well as obituaries and probable descendants on WikiTree.

This is how I see it too. It'll be obvious to anyone where those aircraft have come from. Poland isn't going to deflect responsibility this way.

Poland can't afford to donate it's air power so readily, but the USA allows them to with this move. It will also shift their military to be more on spec with other NATO countries.

Russia does not need allies to defeat the Ukrainian army. Given enough time they will win, even if sanctions/aid to Ukraine make it a pyhrric victory.

Part of the sluggishness has been the desire for the "targeted strike", something that appears to have been reversed with the less discriminate bombing of the last 24 hours.
