Blaming vaccines is easier because it feels like it’s something controllable. Covid is airborne and this is a much more concerning reality. There is no need to panic, we have the science to prevent. Problems can only be fixed however, when we are able to talk about them.

What we are seeing now is just the tip of the iceberg. The focus on blaming the vaccines instead of the virus will only continue to make things worse. Condemning a whole generation that has not even born yet.

New important publication in #LongCovid & #MECFS!

After a viral infection, cells lining our blood vessels can become damaged and enter senescence, similar to accelerated aging. These cells are not healthy, but they also don’t disappear. Instead, they send out constant stress & inflammatory signals.
Manuscript: Virus-induced endothelial senescence as a cause and driving factor for ME/CFS and long COVID: mediated by a dysfunctional immune system Figure shows: Overview of the present hypothesis. Acute viral infections induce endothelial senescence via direct and indirect mechanisms, which is then sustained by immune dysfunction and impaired clearance of senescent endothelial cells. (EC - endothelial cell).

World Health Network was featured in The Guardian as experts urge the WHO to update global guidance: surgical masks are inadequate, and respirators should be standard protection in healthcare settings.

Evidence-based public health matters.

Read the full article here
theguardian.com/global-devel...
Graphic with the text “whn.global” at top left. Headline: “Face masks ‘inadequate’ and should be swapped for respirators, WHO is advised”. Subheadline: “Experts are urging guideline changes on what health professionals should wear to protect against flu-like illnesses including Covid”. Below is a side-by-side photo: on the left, a man wearing a blue surgical mask; on the right, a person wearing a white FFP2-style respirator and a black hat and scarf, facing each other in profile. Caption under the photo: “Surgical masks, such as the one on the left, which became ubiquitous during Covid, should be replaced by respirators like the FFP2 face mask, right. Composite: Robin Utrecht/Shutterstock”. Bottom text: “The World Health Network is a network devoted to global compassion—working together to inspire collective action through science for a safer, healthier world.” Graphic with the text “whn.global” at top left. Centered excerpt text reads: “The WHO has been criticised for being slow to describe Covid-19 as spreading via ‘airborne’ particles and the letter also calls for it to revisit earlier statements and ‘unambiguously inform the public that it spreads via airborne respiratory particles’.” Next paragraph: “Prof Trisha Greenhalgh of the University of Oxford, whose research is cited extensively in the letter and is one of its signatories, said: ‘A germ that does not get inside someone cannot make them sick. By sealing against the face, respirators force airflow to pass through them, filtering out the airborne germs. Respirators are designed to fit closely around the face and meet high filtration standards. Medical masks, in contrast, fit loosely and leak extensively.’” Final paragraph: “The letter’s supporters include members of the World Health Network, prominent US epidemiologist Eric Feigl-Ding, and Guardian columnist George Monbiot.” Bottom text: “The World Health Network is a network devoted to global compassion—working together to inspire collective action through science for a safer, healthier world.”

Let's humanize A.I. What could possibly go wrong?
@perrybiblefellowship
Comic from @perrybiblefellowship that shows scientists observing a robot admiring a flower and a butterfly in the first square. In the second square, a scientist places a human heart inside the robot, saying, "Today I shall give you what you've been missing." 3rd square shows the scientist saying: humanity. The last square shows scientists observing the robot killing all life forms around it.

If you're wondering how the medical community can ignore a disease that causes all of the damage laid out in the thread below, take note of the fact that continuing medical education processes are so outdated and ineffectual that many can't even recognize #longCOVID when they get it themselves.

Just published on @pnas.org how #COVID can lead to loss of dopamine neurons. In mice, it can be mitigated with proper treatment, but in humans we don't know yet. Below you see the reduction of TH (rate-limiting enzyme to produce dopamine) in the brain. This is #LongCovid and also viral Parkinsonism.
Manuscript: Combination antiviral and anti-inflammatory therapy mitigates persistent neurological deficits in mice post SARS-CoV-2infection. The figure shows reduction of TH quantification in SN of patients with COVID-19 in comparison with uninfected controls

The internet is full of A.I & bad news now, so I'm doing my part to make it prettier with some NeuroArt ☺️. This is my favorite microscopy image from this project: 🟡 shows neural stem cells during embryonic brain development guiding neurons 🟣to their final location.🔵shows macrophages/microglia #Neuro

Antivaxxers like RFK Jr love to cherry pick policies from countries like Denmark so they can falsely justify reducing vaccines in the US, while ignoring context.

If they really wanted to learn effective health policy from Denmark, they would be pushing for universal single-payer healthcare.

Figure from the review: COVID-19 in pregnancy: implications for fetal brain development (DOI: 10.1016/j.molmed.2022.02.004 ) Legend for the figure: (A) Maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection results in maternal immune activation (MIA) and increased proinflammatory cytokines in the maternal periphery. (B) Maternal SARS-CoV-2 infection can impact the placenta via two mechanisms: (i) placental immune activation and inflammation resulting from MIA (likely most common) or (ii) direct placental infection with SARS-CoV-2 (rare per the current literature). Placental immune activation and inflammation are associated with placental Hofbauer cell activation or priming, increased natural killer (NK) and T-helper 1 (Th1) cells at the maternal–fetal interface, increased proinflammatory cytokine production, upregulation of interferon-stimulated genes (ISGs), placental serotonin dysregulation, and increased oxidative stress. When direct placental infection with SARS-CoV-2 occurs (which is rare with the ancestral and other pre-Delta strains), the syncytiotrophoblast and cytotrophoblast layers are most commonly infected, and once the virus gains access to the intervillous space, it can theoretically gain access to the fetal circulation. (C) Both MIA and placental immune activation can lead to fetal brain immune activation, inflammation, and altered neurotransmitter signaling, including the serotonergic, dopaminergic, melanocortinergic, GABAergic, and glutamatergic systems. Fetal brain immune responses are associated with microglial priming, altered neural progenitor cell proliferation, impaired neuronal migration, synaptogenesis, and axonal targeting, all of which can result in altered offspring neurodevelopment. (D) Offspring affected by MIA are at increased risk for attention hyperactivity deficit disorder, autism spectrum disorder, anxiety, depression, impaired cognition, learning disabilities, and schizophrenia.

"Of the 18 124 live births, 861 infants were exposed to maternal SARS-CoV-2 infection.

About 16% of children whose mothers tested positive for #COVID during pregnancy were diagnosed with a neurodevelopmental condition by age 3 years, compared with about 10% of those whose mothers tested negative."

Here's a really easy New Year's Resolution:
If you're sick with something contagious, you will stay home if your circumstances allow.

If you can't stay home, you will mask around others until there is no possibility you are contagious.

By making these choices, you will literally save lives.

The COVID-19 iceberg.

These numbers are just the tip of the iceberg. Reported cases only show a fraction of what’s really out there, but they still give us some sense of what’s going on.

#COVID19iceberg #COVIDisNotOver #COVIDisAirborne #MaskUp😷
An image of a large iceberg floating in the ocean, with the small visible tip above the water labeled “REPORTED CASES.” The massive submerged portion beneath the surface is labeled “UNREPORTED CASES.” In the center of the iceberg, the text “COVID-19” is written, illustrating how reported infections represent only a small fraction of the true number of cases.

While in the U.S. this topic became politicized, Germany just committed US$582 million to post-infectious disease research. With #COVID and now with the #BirdFlu risk, we are witnessing a major leadership shift, with the U.S. losing ground to Europe, and Germany now leading the way.
