🧵 #MedTwitter IMPORTANT
The case of this 🇨🇦 adolescent with #H5N1 #BirdFlu is terrifying. Her only medical history was mild asthma, & symptoms started w/ fever and conjunctivitis. On d5 from symptom onset, she was admitted in respiratory failure, kidney failure, in shock … /1
Despite 3 antivirals (oseltamivir, amantadine, & baloxavir) to which her virus appeared to be susceptible & plasma exchange (three times !!), she spent 2 wks on ECMO and almost 3 wks on a ventilator and was dialysis-dependent. She survived. Let her be a warning, #MedTwitter /2
In an H5N1 outbreak, if even a small % of people get so sick, hospitals are in trouble. If a #H5N1 virus gains ability to spread btwn humans & enters widespread circulation, humanity is in trouble. No amount of #publichealth effort or cost to prep for #BirdFlu is too great. /3
Evolution of #H5N1 virus in a way that makes it more dangerous to humans has already been detected in individual patients during illness. We must ensure such viruses do not enter the genl population, which could produce a #BirdFlu #HPAI #pandemic. /4

#MedTwitter #H5N1
We need:
👉Improved indoor air quality, esp in crowded &/or essential public spaces (schools a top priority)
👉Clear messaging about value of masks & handwashing, as well as avoiding personal/pet contact w/ sick/dead birds
👉Universal paid sick leave
AND
/5
👉Safe, effective, affordable, & readily accessible vaccines & drugs to prevent/treat #H5N1 #BirdFlu.

The time to do all of this is now, not when we are in a crisis that would have major implications for human health/survival as well as the economy on a global scale.

#MedTwitter
You can read more about the case of the Canadian adolescent here, & everyone who sees patients in any specialty should read it because we learned from #COVID19 that in a #pandemic, we WILL all be called upon to help in some way:

The risk of #H5N1 #BirdFlu to genl public (w/o contact with ill/dead birds etc) is low at this time per @WHO. What we must let the public know is that that could turn on a dime. We should have prepared so well that if it does, we can run that play in our sleep. /End

NEW Analysis of 641K hospital admissions in 3.5y finds ending universal masking & #COVID19 testing was assoc w/ a 25% ⬆️ in hospital-onset resp viral infections (w/ longer stay & ⬆️ mortality) & resumption of universal hospital masking with a 33% ⬇️. #WearAMask /1
#MedTwitter
The ⬇️ in respiratory viral infections w/ universal masking included #COVID19, #influenza, & #RSV: .

We need universal masking in hospitals, especially now when #SARSCoV2, #flu, & #RSV levels are high nationwide based on wastewater testing. /2 ja.ma/3Z5fdn7Image

#MedTwitter
The study didn’t assess #longCovid (LC) risk but given that preventing #COVID19 is the only reliable way to prevent LC, universal masking in hospital would likely also ⬇️ LC risk. In my opinion, lack of universal masking should be a hospital quality measure. /3

President Jimmy Carter died today at age 100, having lived w/ melanoma that had spread to his brain & liver for >9y. I grew up in GA admiring him, so as an oncologist, I’d like to honor his life by teaching you a bit. #melsm #MedTwitter

First, the ⚠️ signs (ABCDE 👇) & pics

It’s important to know who’s at ⬆️ risk for #melanoma (see 📸 ).

UV exposure (☀️ or tanning bed) is the major risk.

Having 5 sunburns doubles your lifetime risk of melanoma. Age matters. Even ONE blistering sunburn as a kid/teen doubles lifetime risk!

🔑 AVOID BURNS! /2 Image
People with dark skin can also get melanoma (though they are at much lower risk than people with fair skin).

And #melanoma can appear in unusual places including some you might not expect like your nails or even areas that get little or no sun exposure. /3

NEW 📣 Nat’l study in #Sweden: 86% of people on sick leave due to #COVID19 in wave 1 of #pandemic still had symptoms 18m later, esp fatigue, cognition, sleep, movement. Risks higher if hospitalized or female. Vax didn’t exist then.
#MedTwitter #LongCovid

The study also found nearly half of respondents also had problems w/ functioning in daily life 18 mos after they were infected w/ #COVID19. That is #LongCovid. This is a stunning number.

Sweden never had a full lockdown or mask mandate in wave 1. /2

#MedTwitter
With this approach, #COVID19 deaths were noticeably higher in #Sweden than in neighboring countries with more precautions. For example, see this graph from ABC based on a Johns Hopkins analysis of the region. The King said: “I think we have failed.” /3 au.news.yahoo.com/leaders-tragic…

NEW Longest prospective study of #LongCovidKids: 1.3K kids who tested pos for #COVID19 were followed up to 3y. Of note, 89% of cases were “mild” & 9% had no symptoms, & 80% had zero doses of vaccine. Mix of variants, but most were Omicron then Delta. /1 thelancet.com/action/showPdf…
Image
Sadly, 23% of kids had #LongCovid at 3 mos. While #s fell over time, 13% at 6 mos, 8% at 1 yr, 6% at 18 mos, & 7% at 2 yrs still had #LongCovid. This is tragic, both because it means that 1 in 12 kids are still suffering a year later, & most of those remain ill longer term. /2
Adolescents/teens were at MUCH greater risk than age <12, as were those infected by earlier variants. Females & those w/ comorbidities were also at slightly increased risk. Infection w/ orig variant resulted in ⬆️ autoimmune disease. Vaccination reduced risk of #LongCovid. /3 Image

#MedTwitter #NurseTwitter I have a small but important rant about medical gaslighting. I booked a pharmacy appt for vaccines for myself & my family. This evening when we all went to get them, the pharmacist said to me: “You only booked an appt for yourself, not the others.” 1/
No, I’m sure I booked all of us. I had actually booked a time & when it didn’t let me add others, I had cancelled & rescheduled for an hr later when they could take us all. I explained that to the pharmacist who could SEE the cancellation & rescheduling just as I said, but… /2
She then said “but you didn’t book anyone else, just you.” I insisted I did & described the lengthy process of having to re-enter all the same info (address, insurance info) over & over for each of us. She acknowledged that’s how their computer system makes you enter it… /3

Great to see independent groups demonstrate that passive transfer of IgG from people w/ #longCovid (LC) to mice produces symptoms.

A few reactions:

👉 We need #clinicaltrials of repurposed drugs (& novel agents) to treat autoimmune disease now

BUT…
We have GOT to be able to identify patients w/ #longCovid who instead (or also) have persistent #SARSCoV2 &/or other reactivated virus. If we immunosuppress them (w/o treating 🦠), we can inadvertently harm them AND potentially abandon therapy that could help others w/ LC.

2/
Our ability to get products into the 🧠 will be more important than ever. That might be products that already cross the blood-brain barrier or novel product delivery strategies (devices to ferry a product across the BBB or strategies to open/close BBB like a drawbridge).
