Would you drink the glass of water on the left? If not, why are you still breathing in dirty air in poorly ventilated indoor spaces? 17/

Prenatal SARS-COV-2 infection in pregnant women is linked to developmental delays in toddlers: "At 6 months, 33.3% of infants exhibited cognitive delays, 20% communication delays, and 40% motor delays, increasing to 35.71%, 64.29%, and 57.14% at 24 months, respectively."

Hey Space Weather Watch, the two photos below, one the clearest picture of the sun taken by NASA Sun & Space, and the other is my photo of nerve fibers in the brain using the microscope. Close enough? Does nature repeat itself?😜☀️🔬

Post-COVID cognitive decline is real - and visible in the brain. A new study used brain imaging (PET) + EEG to analyze people with “brain fog” months after mild COVID-19. They found: suppressed brain metabolism slowed brain waves even in those never hospitalized.🧵

Hospital-acquired/ nosocomial #COVID infections should be "never events". This is happening now in 70 hospitals in 🇨🇦 (from 10 provinces & 1 territory) participating in Canadian Nosocomial Infection Surveillance Program. BC hospitals are well represented health-infobase.canada.ca/cnisp/viral-re…

2- But Omicrons use endocytosis right? They no longer use TMPRSS2? They don't cause cell-cell fusion? Yes and no..... For the longest time we see primary Omicron cultures that look like this:

Read Stuart Turville latest pre-print on how COVID changed with Omicron to use receptor binding differently ( biorxiv.org/content/10.110… ).

"A submaximal 2-day CPET protocol revealed a reduction in oxygen uptake, oxygen pulse and partial pressure of end tidal carbon dioxide, suggesting dysfunctional oxygen transport, utilisation or both may contribute to long COVID"

More on this! More screening should be done prior to contrast studies. Apart from kidney function, high-oxalates, vitamin supplements, microbiome composition (low oxalate-degrading bacteria), & genetic differences can create a recipe for significant harm. udshealth.com/blog/hidden-ri…

🚨 Model X2 Update! 🚨 The SEN66 sensor was a bit too chill about wildfire smoke. 😬 We ran tests. We saw the issue. The new Model X2 will use SEN55 + SCD30 for better outdoor PM. 🎁 Free replacement for all X2 owners! 📖 visiblair.com/products/real-… #AirQuality #WildfireSmoke

🚨 Mise à jour Model X2 ! 🚨 Le capteur SEN66 aime la poussière, mais la fumée dehors ? Il fait semblant de rien.😅 On a testé, confirmé, et réglé. Le nouveau X2 aura SEN55 + SCD30. 🎁 Échange gratuit pour tous les proprios ! 📖 visiblair.com/fr/products/re… #AirQuality #WildfireSmoke

Interesting comparison of different PM sensors outside the lab. Great customer service to replace with a better functioning model.

Let’s talk about COVID, brain damage & society. Specifically, what happens when a neurotropic virus repeatedly infects the population, targeting the frontal lobe & almost nobody talks about the consequences? This thread is for the skeptics. I’m a neurologist, stay with me 🧵

If you listen to one thing about Long COVID this month, it's this. So sad I missed this months ago. viavid.webcasts.com/viewer/event.j…

In long COVID patients, researchers observed chronic immune dysregulation, exhausted T cells, and reduced cytotoxic NK cells hallmarks also seen in viral-related cancers.

Good News! Canadian Standards Association (CSA) has called for universal respirator use in healthcare settings & when performing patient care outside of healthcare settings (eg – in the home) in the latest edition of CSA Z94.4, Selection, use and care of filtering respirators.

How you can help: The draft CSA Z94.4 Standard is now out for Public Review until August 19, 2025. Please weigh in with your positive, constructive comments at publicreview.csa.ca/Home/View/2256… . Public Review comments are open to everyone who registers.

Here is your chance to provide constructive feedback on the proposed updated Canadian Standards Association (CSA) respirator standard which calls for universal respirator use in healthcare settings & when performing patient care outside of healthcare settings (eg – in the home).
