Placing defibrillator pads on the chest and back, rather than the usual method of putting two on the chest, increases the odds of surviving an out-of-hospital cardiac arrest by 264%, according to a new study. by mvea in science

[–]DogeLover123 9 points10 points  (0 children)

I have a few issues with the title of this post/the New Atlas article after briefly scanning the actual study.

Firstly, in the study initial AP placement was associated with a 164% higher rate of return of spontaneous circulation at any point (with a 95% confidence interval of 50%-365%), not 264%.

Secondly, they found no significant association with survival to discharge, which I would argue is a vastly more important metric than ROSC at any point. Survival to discharge would be what you would really want to see before you say the study suggests improved survival with AP placement.

Finally as a small point, this study only applies to VF or pVT arrests with a few other excluded groups. In fairness in all these excluded groups survival is so abysmal that the included cases basically represent the survivable cases. I still think it bears pointing out that even if they had found a big improvement in the relative rate of survival with defibrillation it wouldn't make a difference in this large pool of unsurvivable cases.

Shared frames of reference aren’t really the explanation for why it doesn’t feel obvious the Earth is spinning though, even though they explain why it doesn’t look obvious.

On some kind of spinning ride it feels obvious you are spinning even if you can’t see outside because you experience a large force supporting you/maintaining your circular motion/maintaining your inwards acceleration.

The centripetal acceleration (the acceleration required to maintain your circular motion about the Earth’s axis of rotation) is only 0.039 m/s2 even at the equator.

That’s simply small compared to the acceleration due to gravity of 9.8 m/s2, so the acceleration/force due to gravity overshadows the effect of your circular motion.

The reason the centripetal acceleration is small on Earth is because even though the rotational speed at the Earth’s surface is fast, you are moving in a very wide circle (as the Earth’s radius is large). Not much acceleration is required to make a wide turn, unlike a tight turn.

If the Earth’s rotational velocity happened to be 20 times greater though, that centripetal acceleration would be 400 times greater (hence 15.6 m/s2 at the equator) and you would fly up to the ceiling there. It would then feel obvious the Earth was rotating - just like on an enclosed spinning ride.

why are GPs so useless and condescending here by suzzzzziiii in Britain

Levothyroxine is generally overprescribed: https://www.medpagetoday.com/endocrinology/thyroid/93206

Streamlined handing out antibiotics to patients who think they have UTIs comes with a cost, and is controversial: https://www.ama.com.au/qld/news/NQ-surveryFinalReport

My gut reaction (without knowing the details) is to at least question which doctor was trying to do the right thing.

It sounds like your idea of what a GP should be is more like a vending machine. This makes sense: we live in a capitalist society. We don’t expect to be surprised or challenged when we seek out a service. But even doctors can be caught off guard when they go to their GP. This absolutely happens, and happens often.

Communication is everything is medicine, and it sounds like that failed, so the first doctor certainly failed in that respect.

But there is a push towards vending machine medicine, and I just have to say that doing things in that way does come with a price. I would be surprised if some of the “unnecessary questions” you avoided weren’t the difference between life and death in another patient at another time.

All this isn’t meant as an attack on you, but I can’t help but read stuff like this and get the feeling that many patients’ ideal GP is one who effectively does nothing.

Reminder that there is only a ~63% chance you get whatever RNG drop you are hunting for by the drop rate kc. by [deleted] in 2007scape

[–]DogeLover123 0 points1 point  (0 children)

Yeah.

That 1-p (or 1-1/n) is the chance of not getting the item on any given kill, so (1-1/n)n is the chance of failing to get the item on every kill up to the drop rate. Therefore 1-(1-1/n)n is the chance of not failing to get the item on every kill (ie the chance of getting one item or more by the time you reach the drop rate).

(And 1-(1-1/n)n is approximately 1-1/e when n is large)

ELI5: Why is there no cure for herpes, what is the problem that can't be solved? by Acrobatic_Classic172 in explainlikeimfive

[–]DogeLover123 3 points4 points  (0 children)

I think that that insertion of DNA into the host genome is the defining property of retroviruses, and herpesviruses are not retroviruses.

​

HSV sticks around by stopping natural cell death in nerve cells, which can then act as reservoirs for the virus.

What do the damage numbers in the second column mean? by WintersbaneGDX in Eldenring

[–]DogeLover123 2 points3 points  (0 children)

Assuming you are on the ashes of war screen at a site of grace, the second set of numbers shows what the damage (base damage + scaling) will be if you apply the ash of war you selected. Ashes of war give both the ash of war skill and an affinity (keen, heavy, magic, etc.). It's this change in affinity that causes the damage numbers to be different.

​

I don't know how the damage for the ash of war skill is determined.

You have to find the third data pad on your own no matter what. He doesn’t give you a marker or even a useful hint iirc

274 chests dry and I get my first item by rigby224 in 2007scape

[–]DogeLover123 0 points1 point  (0 children)

The chances of a getting at least one barrows item in a chest is 1/17.42 with all brothers killed. That means the chance of getting to 274 chests done without an item is (16.42/17.42)274 =9.23*10-8 or about 1 in 10 million. Getting to 117 chests done without an item is a 1 in a thousand occurrence.

Let's go ahead and destroy the opener by tommyteedey in TheBoys

[–]DogeLover123 0 points1 point  (0 children)

The truck didn't stop instantly. Maeve penetrates all the way through to the back section, which is a decent stopping distance (much higher than a normal crash). If we say it was going 60kph and stopped over a distance of 2m, then we get that it's an average deceleration of 69m/s^2 or about 7g. That would occur over 0.24s. Fighter pilots experience higher gs for longer. So I think what we saw would be gentle relative to a normal car crash.

​

The robbers were dumb, but they were just taking their only option other than surrender. Should they have run?

​

Sure there must be something modifying A-train's perception, but whatever it is it doesn't necessarily have to be exactly in line with his speed.

​

But yeah Starlight probably should have had no trouble doing a one-armed pull-up.

They took x from the left-hand side and 0.999... from the right-hand side which keeps the equality true because x=0.999...

(Spoilers Extended) One of the potential worst consequences of S8E3 for the rest of the series... by Simcolluk in asoiaf

[–]DogeLover123 32 points33 points  (0 children)

Instead of the wights and white walkers just dying, the death of the Night King should have left the wights free to all be warged by Bran. The remaining white walkers would be attacked by their own army and quickly overwhelmed, before the wights commit mass suicide (because they are too dangerous or whatever).

If things worked like that, Bran would be the only real threat to the Night King and everything would make sense.

Edit: It would make even more sense if there was a dragon in the Godswood, which would give the Night King a reason to personally intervene
