All those people who refused to take COVID seriously have a lot of blood on their hands.

[–] Wogi@lemmy.world 91 points 2 weeks ago (1 children)

Shout out to Physics Girl Dianna. Who is still bedridden.

[–] onyxjet@lemmy.world 27 points 2 weeks ago (2 children)

STILL? I haven't checked in months. That's crazy.

[–] pyre@lemmy.world 33 points 2 weeks ago

yeah her YouTube channel still posts updates from time to time. shoutout to her husband too. they got married and almost immediately became patient/caretaker. it's probably exhausting for both but they're both resilient, hopefully they'll get out of it and live a stress free happy life. sure deserve it after going through this.

She has shown small improvements, but it's excruciatingly slow.

They don't remember. On account of their brain injury.

[–] JackbyDev@programming.dev 19 points 2 weeks ago

No, not everyone who got long covid didn't take it seriously. But the people who were super spreaders or spread misinformation are certainly to blame.

[–] AnxiousOtter@lemmy.world 19 points 2 weeks ago

They don't give a shit, unfortunately.

[–] Evil_Shrubbery@lemm.ee 11 points 2 weeks ago

But fortunately a lot of them don't care about such things as the quantity of blood on their hands, so news like this won't worsen their lives or self-image.

They got their Applebees. Does’t matter.

Ooo interesting. The parallels with CFS are fascinating.

[–] Varyk@sh.itjust.works 54 points 3 weeks ago (10 children)

I wasn't even aware of that. chronic fatigue syndrome was actually real.

I thought I was just like side- depression.

is there anything known about CFS?

what causes it or how long it lasts or anything?

I know nothing about it except for like a comedy sketch from the 2000s at some point.

[–] FundMECFSResearch@lemmy.blahaj.zone 68 points 3 weeks ago* (last edited 3 weeks ago) (2 children)

Lifelong disease usually triggered by viral infections. Very functionally disabling.

Known immune abnormalities which seem to affect the brain and mitochondria. I think @Neurologist@mander.xyz is specialised in it.

Also “chronic fatigue syndrome” was the name back when it was classified as psychological. Now that it’s classified as neuroimmune the name has been changed to Myalgic Encephalomyelitsis (ME) (Or ME/CFS).

As usual though for a medium quality source like ScienceAlert, the article is written by someone who has no specialisation in Long COVID/ME, or even medicine. So there’s a bit of oversimplification and overstating findings from one study in that article. Very few researchers think it’s a brain injury. Most think the immune system has been compromised (with some deficiencies and abnormalities) and it’s affecting the brain in unknown ways (hence the abnormalities found. It’s weird though because the immune system problems seem to cause some immunodeficiencies but also autoimmune reactions. They’ll need to be quite a bit more studies before we get a clear picture.

[–] Neurologist@mander.xyz 27 points 3 weeks ago* (last edited 3 weeks ago)

Couldn’t have said it better. And yes, science journalism often is basically repeating and dumbing down what a study says, but in science, and especially in medicine, a lot of studies tend to be wrong, make false assumptions, or overstate their findings, while journalists tend to take them for their word. There’s a reason you hear of a new cancer treatment in the news every other week but few actually make it past FDA approval.

[–] Varyk@sh.itjust.works 12 points 3 weeks ago (10 children)

wow, thank you so much for the detailed answer, I'm fascinated chronic fatigue syndrome turned out to be a neuroimmune disorder.

is ME genetic or do you just get unlucky as far as we know so far?

[–] FundMECFSResearch@lemmy.blahaj.zone 18 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

We don’t really know. But theres a giant GWAS (Genome Wide Association Study) called Decode ME with I think upwards of 25’000 pariticpants which is coming out in the next year. So we’ll know a whole lot more then. Hopefully it might lead to treatments.

CFS is a syndrome rather than a disease because, until recently, it only presented as symptoms instead of as an identifiable problem with a person. I know that a some people who get diagnosed for CFS get later diagnoses as neurological disorders like multiple sclerosis.

It sounds like the more powerful MRI scanners are seeing inflammation in the rest of those suffering from CFS.

That would mean CFS is a lifelong degenerative condition.

[–] Neurologist@mander.xyz 29 points 3 weeks ago* (last edited 3 weeks ago) (12 children)

Hey I’m a researcher who works on ME (in the past called CFS).

ME/CFS is currently classified as a disease/biological illness according to the CDC.

ME is a disease state in itself. We don’t know much about it, but it can’t be explained by other diagnoses, as the defining factor, neuro-immune abnormalities including immune activation showing up post exertion is unique to it. You’re completely right that we don’t yet have a reliable biomarker. We have a test that differentiates from healthy controls, but it was discontinued for ethical reasons because conducting the test leads to a sometimes permanent worsening of the illness.

In the past it’s been mixed up and jumbled a lot, but the picture is getting clearer.

There have been a few case reports of degenerative forms of the illness. But in general it takes a more classical relapsing remitting pattern. Although even in less bad stages some patients are severely functionally disabled, even bedridden and tubefed. It has a really wide range of severities with the least severely affected able to work part time and walk and travel, while the most severe might not even be able to communicate.

I wish people cared about dealing with covid still. Once corporate America got that sign off not to care there was no going back.

[–] SOB_Van_Owen@lemm.ee 29 points 2 weeks ago (1 children)

Seriously. I spent 2 days in the hospital last week with bilateral pulmonary embolisms after having COVID the middle of last month. I was NOT otherwise at risk for clots. A terrible surprise that I'll no doubt be recovering from for some time. I'm on a blood thinner for 6 months.

great.

remember when all the politicians and people who control things got covid?

If it makes you feel any better, those demographics were already suffering from lead gas exposure.

I'm still afraid of long-c. I insisted that we wore masks in airports and on flights when we took a trip last month. We live life in a normal fashion everywhere else (because we're vaxxed and boosted), but I wasn't willing to risk that environment.

[–] Knock_Knock_Lemmy_In@lemmy.world 17 points 3 weeks ago (3 children)

Why just planes? Surely this would apply to all public transport.

[–] janNatan@lemmy.ml 87 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

If they're US American, a plane is likely the only public transportation they've ever taken. If they live anywhere remotely rural, it's likely the only one available to them.

[–] Corkyskog@sh.itjust.works 10 points 2 weeks ago* (last edited 2 weeks ago) (5 children)

I was going to say "almost every American takes a school bus at one point in their life" then I looked it up and was disgusted to find that recently more children are driven to school than take the bus.

[–] janNatan@lemmy.ml 13 points 2 weeks ago (1 children)

It's absolutely ridiculous how many people drive their kids to school. The traffic reduction during fall break last week was astounding.

[–] Alienmonkey@lemm.ee 12 points 2 weeks ago (2 children)

It's absolutely ridiculous how hard the school systems make it to get on a bus route.

You basically have to stay at the same residence and at the same school for their entire education. Even just moving within the district and they use it as an excuse to "put you on a wait list".

Add in the shortage of drivers (who wants that job) and any excuse they can use to change boundaries or cut a route.

It's like the fucking DMV on steroids.

Airports and planes see a lot of traffic from all over the world constantly rotating through. With some variation depending on the size of the city and your personal schedule, you're running into more of the same people on normal public transport.

[–] catloaf@lemm.ee 9 points 3 weeks ago (1 children)

And you're in very close proximity for a very long time. I don't know how HVAC works on an aircraft but I assume there's a large amount of recirculation.

I was on buses and trains this morning. They weren't nearly as crowded, the trips were a lot shorter, the air moved around at every stop, and like you said, they're all pretty local, so low risk of someone importing weird diseases. At least on the subways, you should still wear a mask if only because of the air quality. There's a lot of brake dust floating around.

As someone with long COVID, I can vouch the debilitating mental effects. I was teaching math to 4th through 8th grade students when I got it. I can remember standing in a classroom talking about a lesson and just having my mind go blank in mid sentence. I couldn't function. Not knowing what I was talking about or even where I was. Thankfully the students where very understanding and someone would finish my point I was making. I still suffer from it yet today, nearly 2 years later.

I have respiratory issues despite every CT scan showing nothing more than a couple of small pneumonia scars form long ago. I should be able to breathe just fine with no reduction of lung capacity. It stems from a lack coordination with my diaphragm - It runs backwards when I exert myself causing shortness of breath. Another sign of probable brain injury. And despite using a therapy tool to try and fix the issue, at best it just helps a little.

The upshot is I have pretty much stopped doing a lot of things I used to do because of the difficulties breathing and I spend a lot more time away from people due to an unreasonable fear of COVID.

It has caused me to retire earlier than I wanted to. And my life has greatly changed - and not for the better either.

[–] just_another_person@lemmy.world 9 points 2 weeks ago (1 children)

Sorry you're going through all of that. There obviously aren't any long term studies on it yet, but hopefully things will improve more and more over time.

[–] bluewing@lemm.ee 9 points 2 weeks ago (2 children)

According to my Pulmonolgist - Nope. Her observations of all her patients over the years is that if you don't get over it in about a year, you don't get better. And she has been seeing more COVID patients than her "normal" patients for several years now. Long term care is going to be a real problem for society going forward.

What turns regular COVID into long COVID? When I got COVID I was better after 2 weeks but I had a nagging cough and chest discomfort for 2 months

[–] just_another_person@lemmy.world 70 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

It's very subjective. You can read more about it by searching around, but the prevailing definition means people who had more severe reactions to the infection than the average patient, which almost unanimously means a severe and prolonged inflammatory response.

What they are finding more and more is that this specific virus triggers undiagnosed or dormant autoimmune responses in patients. If you're familiar with Rheumatism at all, imagine a massive reaction to, say, twisting your ankle, but it goes out of control and causes swelling all over your body including your brain, lungs, heart, and renal system. This is actually what killed the most patients pre-vaccination.

The full body assault of an inflammatory response just makes the body unable to cope, and things start shutting down. It can kill children and older people very easily if you can't get it under control. Many succumbed to Pneumonia, but those that lived had damage to their major internal organs from the inflammatory response. You can also see some had been using the term "Walking COVID", meaning people who had cleared the infection, but had long term sustained symptoms similar to Emphysema. They've since just moved on to calling everything "Long COVID". Some people recover, some people don't.

This study finally identified the specific damage and detection to brain activity.

[–] JustZ@lemmy.world 24 points 3 weeks ago* (last edited 2 weeks ago) (4 children)

People don't get it. The inflammatory process can do these sort of thing to any organ or system, or parts of them.

People got a thing called COVID Toe. This is where you and every person already has some fungus that live on their feet and which gets into the skin and toenails. Maybe you have a little yellowing of the toenails or you're just "prone to athletes foot."

Then you get COVID and suddenly your immune system is working overtime. The fungus starts to multiply faster and spreads more aggressively. Your toes start to get itchy and red, more than usual. They swell. They yellow. Then they start to crack and ooze, possibly requiring surgical debridement or in the most severe cases, such as where the patient already had diabetes affecting their peripheral nerves, amputation of the foot to prevent necrosis and sepsis. Imagine dying from athletes foot because your immune system was overwhelmed fighting a coronavirus.

Diana from YT Physics Girl has long COVID. Her very loving husband takes care of her. We all wish them the best and any kind of recovery.
