Height difference between two hard floors? by Aniridia in HomeImprovement

Do you think a 1/4” difference would be overly noticeable or a hazard? Thanks!

A raid on half destroyed Mercury would be interesting.

What actually pushes our feces through our large intestines? by gillman378 in askscience

[–]Aniridia 48 points49 points  (0 children)

There is reverse peristalsis within the small bowel in the first phase of vomiting. After that, it's all about ab muscles and changes in abdominal and chest pressure to expel what's in the stomach.

What jobs existed 500 years ago, today, and will most likely still exist in 500 years? by 139Lenox in AskReddit

[–]Aniridia 57 points58 points  (0 children)

I'm a doctor, so I'm biased, but I think this is the key. Just entering symptoms A, B and C into a computer, followed by lab values and imaging findings does not necessarily lead to a diagnosis or treatment. People with the same diseases present different ways, even if the "objective" side of their process is the same. Patient personalities can also dictate how treatment will proceed. The personal side of medicine, such as calming fears and feeling cared for, is something that I don't believe can be replicated by a computer.

Algorithmic detection of recurrent brain tumors in MRI scans nearly twice as accurate as neuroradiologists by shiruken in science

[–]Aniridia 3 points4 points  (0 children)

I was trying to think of an analogy, but I was having a difficult time. I guess something along the lines would be asking a detective to solve a crime but not letting them use fingerprints or DNA evidence. They could do so some of the time, but why wouldn't you let them use some of the strongest tools they have if they're commonly used and widely available?

Going back to my post, you could argue the perfusion sequences (rCBV) are still not mainstream, but the diffusion/susceptibility sequences are used in virtually every brain protocol I can think of (sure, there are a few niche protocols - stealth, etc.) and I don't know why they wouldn't be included in the study. In my opinion, only allowing the radiologist to use the sequences they did meant they were forcing them to make a decision based on an incomplete and unrealistic study.

[–]Aniridia 8 points9 points  (0 children)

Radiologist here (IR, but trained fairly recently in neuroradiology as a resident). According to the materials/methods, only a post-contrast T1, T2 and FLAIR were available for the radiologist to determine necrosis from recurrence. There's no way any rational radiologist would think that would be a complete workup for what this study is asking. Standard DWI/SWI sequences, and newer, but nearly ubiquitous sequences such as relative cerebral blood volume (rCBV) are much more sensitive and specific for the question being asked and are widely available.

My MALE friend has cirrhosis of the liver. Every week he has to get over 7 liters of liquid pumped out of his body by elpintogrande in WTF

[–]Aniridia 4 points5 points  (0 children)

I'm an IR doc, and I agree. I tell my patients that it's not a matter of "if" they (tunneled peritoneal drains) will get infected, but "when." These are reserved as a palliative measure only. Denver shuts can occasionally be a longer term option, but they still fall into the palliative category.

Coffee around the world. by IamtheDenmarkian in interestingasfuck

[–]Aniridia 23 points24 points  (0 children)

Unless "cowboy style" is different from "cowboy coffee," I think there's a bit of a difference between those two and a Moka pot. "Cowboy coffee" is coffee grounds and water in a boiling pot, after which the coffee is poured off, trying to keep the grounds in the pot. You could use a Moka pot over a campfire, but I'd argue that doesn't make it cowboy coffee.

Why do we have automatic reflexes on our knees, what benefit does this have if any? by lolitsaj in askscience

[–]Aniridia 1 point2 points  (0 children)

There are two main reflexes in the knee, the stretch reflex and the Golgi tendon (autogenic inhibition) reflex.

The stretch (myotatic) reflex is what is elicited during the classic "knee-jerk" test. The role of this reflex under normal circumstances is largely for posture. It's probably better understood by thinking of your entire body posture, instead of just your leg. If you are standing, and start to sway to the right (for example), all the muscles/tendons on the right side will start to shorten, and all those on the left side will start to stretch. Reflexively contracting those stretching muscles will cause you to straighten back to the left.

The Golgi tendon (autogenic inhibition) reflex helps to prevent damage from over-stretching/exerting muscles and probably also has a role in equally distributing force over complimentary muscle groups. In simple terms, it is the opposite of the stretch reflex. As the Golgi tendon organ (a special sensory structure) is deformed, it is able to "measure" force. As it approaches a threshold, it inhibits further muscle activity to prevent damage. Think of holding something really heavy for a while, when all of a sudden your arms "give out."

So - knee reflexes are for posture and preventing injury.

Women still outnumbered in medical leadership by men with mustaches, study finds by inspirestrikesback in nottheonion

[–]Aniridia 12 points13 points  (0 children)

I'll leave this here.

TLDR: 40% of female doctors work part time. Female doctors take more extended leave. Female doctors are less productive. Female doctors retire earlier.

[Serious] Doctors of Reddit, have you ever seen someone unexpectedly healing when you thought there was no hope anymore? by sunshineandrainbow in AskReddit

[–]Aniridia 18 points19 points  (0 children)

In short - no. I guess there could be various degrees of "no hope," but there does seem to be a definite point of no return, from which I have not seen a patient miraculously get better. I am surprised from time to time as to the regenerative/recuperative abilities of some patients, but this is typically from injury/illness/operation which would not be considered hopeless to begin with.

To Bungie: More SRL... YEA OR NAY??? by rapister in DestinyTheGame

[–]Aniridia 5 points6 points  (0 children)

Yea. Although if people want racing in between SRL "events" they're going to have to lower the value of drops. As people are slowly ranked up to reputation 3+, getting consistent 310-320 drops will devalue things pretty quickly. With each event add a couple new tracks and bump the drops back up. I enjoy it. It's nice to have something quick and fun to do with a group to break up the marathon raid/strike sessions.

Speed Drawing Black Bolt by Andrew_Harris in Marvel

Definitely not saying it's "wrong" as it looks like you know what you're doing. I just haven't seen that technique with a pencil. It reminds me to Kanji brush technique.

That seems like a weird way to hold a pencil.
