how many modern hildegards von bingen have we lost since the advent of sumatriptan
getting people hildypilled i love to see it
in addition to getting hildypilled everyone who agrees with this should watch the documentary crazywise which is about how pathologizing psychosis is actually a very odd cultural phenomenon and many cultures have important places in their society for people who hear voices and have visions. and how that pathologization might actually make psychosis symptoms worse.
im studying histology and i just like the little guys that work so hard to keep our organisms up and running
easy to miss that one of the reasons maternal mortality is diminished so extremely by modern medicine is that modern medicine makes it so much more possible to identify the pregnancies that will die and take you with them, or are otherwise unacceptably high risk. and then discontinue those ones safely, before it's too late.
thought about this because it's so frustrating when people argue that 'dying in childbirth' is a historical sort of event that doesn't happen nowadays (false) and therefore is irrelevant to the legal status of abortion, since it's not a real danger.
except it super is, and i think a lot of people haven't noticed that this argument in addition to simply being incorrect is basically the same as when people say we don't need vaccines for deadly diseases because no one gets those now anyway.
like yeah one reason for that is we vaccinate everybody ffs.
Note: after the end of Roe v Wade in the US, the maternal mortality rate (and the infant mortality rate) are showing clear increases in the states with the strictest anti-abortion laws.
Forcing people to carry high risk or non viable pregnancies to term kills.
In a surprise attack of astonishing brutality, oral cavity sources confirmed Thursday that the Listerine inside a local mouth was leaving 0.1% of germs alive in order to spread a message of terror throughout the microbial community. “The mouthwash killed my entire colony and then told me to bear witness to the horrors I saw today,” said a rod-shaped Porphyromonas gingivalis, adding that its cell wall was nearly dissolved when suddenly the 20 milliliters of antiseptic liquid retreated, leaving the bacterium with severe but nonfatal injuries.

Remember, history was awful. Never trust the romantics.
#you want to know a sentence that rewrote my brain:#most people have never been 20#more than half of humans ever born never made it to 20#which. is so crushingly sad to me i can't think about it for too long and also weirdly tempering when i'm angry at the state of the world#most people have never been 20! is it any wonder we're bad at being people sometimes! it's so new. we're young to it#anyway#i'm so stupidly grateful to live in the present and for modern medical technology (tags via @thoughtsformtheuniverse)
XKCD: Degree Off
Never Forget what Childhood Vaccines and Antibiotics have done.
The two most powerful words in the English language, owed entirely to the efficacy of vaccines, are thus;
“Smallpox was.”
For most of history, smallpox was (!!!) the scourge that haunted human civilisations. We have evidence of smallpox from mummies c. 1350BCE in Egypt. It’s speculated to be one of causative agents of the Plague of Athens c. 430BCE. There were outbreaks of smallpox in Angola in 1484, in South Africa in 1731 that wiped out entire clans of Khoisan people. There was at least one major smallpox epidemic almost every decade across Europe.
Smallpox was transmitted by droplet/aerosol infection; it tore through even the smallest population centres. Typical smallpox incurred a blistering fever, raised pustules, debilitating joint and back pain; if you lived — and that was a fat fucking if, as typical smallpox had a mortality rate of 30% — you’d have tell-tale pockmark scarring, and face stigma for the rest of your life. Some were left blinded.
The worst form of the disease was haemorrhagic smallpox; all the agony of typical smallpox, with the addition of skin haemorrhage and pinpoint haemorrhage in the spleen, liver, kidneys and gonads. Near-universally fatal, haemorrhagic smallpox made up 5-10% of all cases. Of this number, 72% were children.
The global smallpox vaccination campaigns of 1958 to 1977 were a monumental effort by the World Health Organization and its global associates, backed by incredibly diligent public health work and epidemiological monitoring.
Wherever there were outbreaks, there was herd immunisation. Health bodies campaigned tirelessly for the general population to be immunised. In the ‘70s, a concerted effort was made by the WHO to ensure vaccines were administered in the most remote and vulnerable communities in the Horn of Africa, South Asia and the Pacific.
In 1980, the world was officially, finally free of one of it’s oldest adversaries; universal vaccination had been achieved, and there was no population that could act as a reservoir for smallpox.
If mankind has only one great achievement, it’s the smallpox vaccine; to date, smallpox is the only human disease to be completely eradicated.
After over two millennia of suffering, mass disability and death, humanity finally had the means to give one of it’s biggest threats the biggest possible fuck you, and through scientific and public health collaboration, careful epidemiological monitoring and countless hours of on-the-ground vaccination efforts, managed to blot it from existence entirely.
Where there is vaccine coverage, childhood diseases with high morbidity and mortality rates like whooping cough, diphtheria, influenza B and have dropped.
We have vaccines for TB, another of our greatest and longest adversaries.
With enough effort to counter misinformation, more people fighting for vaccine equality, patent free medication for communicable disease, and universal vaccine coverage, and everyone making sure to keep up to date with their vaccinations, one day, we could be fortunate enough to be able to say;
“Tuberculosis was.”
“Smallpox was.”
Fuck. That hit me hard.
death and the stars
I'm quite fond of the heroes of my field have slain one of the four horsemen of the Apocalypse
One of my friends was a university lecturer who had worked in the lab where the final smallpox case escaped from a lab and killed Janet Parker, a medical photographer who worked in the room upstairs. He was a very funny man, always "on", but once a year when he taught the lecture about smallpox and about 'swiss cheese' risk management, he looked like a dead man walking.
I’ve been thinking a lot about what I want to say for Intersex Awareness Week, and I want to challenge a few myths.
Myth 1: “Intersex people are super rare.”
They’re not. Even the often-cited 1.7% estimate is outdated, it came from limited data in the 90s. Historically, before intersex genital mutilation (IGM) became common, the number of intersex people was closer to 6%.
So why the drop? Because intersex people have been erased, literally and systemically.
• Many of us are sterilized as children without consent.
• Parents are pressured to agree to “normalizing” surgeries on infants, and can even face CPS reports if they don’t.
• Intersex fetuses are often aborted, and infanticide of intersex babies still happens.
That’s not nature making us rare, that’s eugenics.
Myth 2: “There are only a handful of people with each intersex variation.”
Take mine, for example: CAH due to 3β-HSD deficiency. Online sources say it’s so rare only ~60 people have it. That’s not true. I see people diagnosed with this every week in intersex and CAH support groups. The data just hasn’t been updated in decades.
Myth 3: “Everyone is biologically male or female.”
I don’t buy that. The idea of “biological sex” as two neat categories is a social construct, and honestly, it functions like an insurance scam.
My assigned sex at birth wasn’t male or female, it was indeterminate. But insurance and medicine demand boxes, so they make one up.
Doctors don’t even treat “sex” as meaningful when it matters, I’m constantly forced to take pregnancy tests even though it’s biologically impossible for me to get pregnant, all because my legal sex is female. Also, assigned sex at birth, legal sex, and gender identity are three separate things and not everyone has them line up.
What does “biological sex” even mean when:
• Some people have both XX and XY chromosomes,
• Some have ovotestes and produce both sperm and eggs,
• Some women with XY chromosomes can carry pregnancies,
• And some people are born with both a penis and vagina?
Nature is messy, and that’s normal. Being intersex isn’t tragic or broken. I’m proud to be intersex. I’m glad I’m intersex. I’m glad I’m alive.
I want a world where being intersex isn’t medicalized or erased: where sex diversity is celebrated as a natural part of being human.

PSA:
Acetaminophen/paracetamol has a hard stop upper dose limit, above which it becomes extremely toxic.
That limit is 4g (8 “extra strength” (500mg) tablets) in 24 hours (about 2 tablets every 6 hours).
A single dose of 22 extra strength tablets can kill you.
Taking 12 or more tablets per day for more than a week can also kill you (this is about 3 tablets every 6 hours).
Symptoms of overdose take up to 24 hours to manifest, and are fairly difficult to distinguish from other problems. They include abdominal pain (especially right upper quadrant), nausea, malaise, and confusion.
The antidote (n-acetylcystine) must be given within 8hours of ingestion in order to be useful.
After 10 hours the only thing that will work is a liver transplant.
You might think “why would I ever accidentally take so much?”
Well, acetaminophen is in almost everything in the cold/flu/pain aisle. Migraine combos like Excedrin, cold and flu combos like NyQuil, basically anything that says “non-aspirin pain relief”, and anything that’s branded as a fever reducer. It’s all probably acetaminophen/paracetamol.
So the goal of this post is to get you to read the labels on your medications. Because taking taking Tylenol and NyQuil together for a week (like you might if you had the flu) could kill you.
Please don't forget this shit, after it happened to a family member, he died 8 years later because of the continuing health complications even though he survived the initial overdose
I didn't know this for years, and I took so many pills, sometimes 4 at one go, every four hours, like 16 a day, because of endometriosis and migraines. It took a migraine specialist to explain rebound headaches and overdoses when I was in my 40s. Then I went cold turkey on all OTC drugs to get off the cycle. Please, please, if a couple tylenol aren't working for you, talk to your doctor or find one who will listen to you if you can.
being sick & miserable objectively sucks, but it has become significantly easier to cope with since learning that “sickness behavior” is a well documented part of the body’s immune response
feeling not only physically but also emotionally like fucking garbage is unfortunately an extremely effective way to force your body to prioritize fighting infection & keeping you alive. i don’t have to like it, but knowing why i get weepy & pathetic when sick does help at least a little
i just found out that this is not common knowledge and am reblogging so more people know
YOUR BODY DOES THIS ON PURPOSE

Why do I feel like I should print this out, frame it, and hang it in my office?

It’s so crazy that suicide prevention is just people going awwww don’t!! Awwww come on noooooooooo stopppppp
One of the best ones I saw was a thing noting that every single one of the few survivors of suicide jumps off of the Golden Gate Bridge realized, on the way down, that the problems they were killing themselves over actually were fixable or could be worked through...except for the now - extremely unfixable - problem of gravity.
Went to the Holocaust Museum in DC once. There was a video interview of an Auschwitz survivor who said he and some other prisoners stayed up all night with a man who wanted to kill himself. The man didn’t kill himself and survived to liberation.
In the video the survivor said “Never seek a permanent solution to a temporary problem. And they’re all temporary problems.”
Hearing that from a guy who survived the Holocaust rewired my brain a little bit.
I think something a lot of people don't understand is that depression is not suicidality, and suicidality is not depression. People can, and are, depressed without being suicidal, and sometimes suicidality peaks as people are emerging from depression. Suicidality is a wave, and the trick is to allow that wave to crest and subside WITHOUT acting on it. Whatever it takes to ride it out. For some people that's distraction, like watching television. For others it's calling a friend -- not to talk about the suicidality, but just to talk. For others it could be as simple as going to sit in a coffee shop or library, because the presence of other people is a huge diminisher of suicide risk. That's what suicide safety planning is about. It's like having any other type of emergency plan, like a plan for fire or evacuation. It's making a plan when you are in the frame of mind to do so, so that you can just DO the plan without having to think about it when the occasion arises. When you're in the midst of suicidal ideation, or even intent, you're not in a problem-solving mood. So knowing past!you, with the help of a therapist hopefully, came up with the plan and all you have to do is follow up until the wave crests and subsides, is what allows you to see another day.

So difficult to withhold the eyeroll when people say things like, "My body was designed for this" wrt childbirth or whatever, because even if I accept the premise that our bodies were designed, I have to imagine mine was designed with the most basic function of breathing in mind, and yet I had childhood asthma and would have died without intervention so idk if I'm trusting my "designer" with something as physically traumatic and historically deadly as childbirth
"Your body knows what to do" my body tries to close its own throat and die if I encounter a shrimp or perhaps a crab so idk about that one man

It's freaky how the brain will just plasticly learn novel motor output interfaces on the fly. It's almost like instead of hard coding a control scheme for anatomy that changes every few million years the strat that brains went for was to be openly reconfigurable to fit around whatever its nerves seem to be hooked up to via observed feedback.
I think they've done tests on this by getting people to pilot novel bodies in VR. But you don't tend to notice it day to day until something weird happens like just now. I was reading a paper book and it had a line of text blacked out as if redacted. Instinctively I go to move my cursor over the black line to see if I can read any text if I highlight it.
Except it's a book and not my computer screen, so the cursor my brain thinks it's moving across my field of vision in front of me doesn't exist. At the same time, my right hand is making a bunch of small involuntary movements next to me. I didn't intend to move it and didn't even notice it was moving until I saw it with my eyes. What I intended to move was my Cursor, something that my brain had learned to understand that it has, and the way it moves this is by actuating the muscles in my right arm, an action that is entirely disconnected from any intent to move my arm, which is a different thing.
I love being a pattern atop this eldritch mess of neurons, it's great
father I cannot click the book
I learned about this more than 20 years ago and cannot remember most of the details, but there's a whole line of neuropsych research revolving around how the brain manages tool use. One of the topline findings (from 20 years ago) was the neurological foundation of an experience anyone who's mastered a tool can describe. The tip of the tool becomes, mentally, the tip of your finger, right? Especially for pointy stick-like tools where there's a very direct analogue to your actual finger.
Well, we've done experiments where we put electrodes on the surface of people's brains and then have them do various activities. It's not medically ethical to cut a hole in someone's skull just to do this kind of experiment, but if you ever have to have brain surgery for some other reason, you may be invited to Contribute to Science (brain surgery generally doesn't need full anesthesia). Anyway, what we find is, if you poke something with the end of a short stick, the "somatosensory homunculus", which is conveniently right on the surface where we can get at it with the electrodes, lights up as if you were poking it with the tips of your fingers, no matter how you're holding the stick! The actual touch sensors in the tips of your fingers get totally different input when you poke something with a stick than when you poke it directly, but the difference somehow gets abstracted out.
And this happens quite early in the signal pathway, because the somatosensory homunculus is (we thought, anyway) the first stage of touch processing in the cerebral cortex. Which means this capacity for abstraction, for the tool to become an extension of your hand, is evolutionarily old. Older than mammals, probably.
