Quantitative particle count fit testing is a solved problem that is already implemented in the industry, it’s just not standard because the equipment to do it costs more.

To test an FFR, you have to punch a port into a sacrificial mask for the sampling tube - punches and grommets are used. Another sampling tube samples from just outside the mask. The difference between the two sample’s particle counts is the total inward leak rate. The qualitative fit test does use up at least one FFR per user - which is one of the reasons why fit testing was often omitted during the N95 shortages.

For elastomeric respirators, manufacturers sell adapters for the sampling port.

We do have civil forfeiture in :canada: (it occasionally bubbles up to public awareness but isn’t quite the law-enforcement fundraiser it is in the :us:). I think GoFundMe is just getting ahead of what would otherwise be rather unfortunate (for it) government action.

Edit: With so many Canadians in Florida, maybe DeSantis thinks Florida has become a province… :thinking: …

Tracking long COVID in the blood

Dug out the science. My (usual disclaimer here, I’m not a medical person or physician) impression is that this story concurs with things to which @anon29537550 has alerted us. “Aptamer” doesn’t seem to have come up in our discussions. I found a survey article and they sound like some seriously cool work. Berlin Cures’ BC 007 seems to have been “on the shelf” and had success in an initial clinical trial with 4 Long COVID patients, leading to near total remission.

Within 48 h after a single BC 007 treatment, GPCR-AAbs were functionally inactivated and remained inactive during the observation period of 4 weeks. This observation was accompanied by constant improvement of the fatigue symptoms of the patient, taste, and retinal capillary microcirculation.

  • Physical phenotype of blood cells is altered in COVID-19 (very cool, but fundamentally straightforward measurement approach “real-time deformability cytometry”. Strictly “mechanical” measurements, but this pegs my very geeky “nice work” meter. Dr. Bettina Hohberger’s group are looking like rock stars…)

We identified significant and persisting changes of cell size and mechanical properties in acute-phase and post-COVID-19. These changes might be predictive for cell functionality such as oxygen delivery.

Work continues…

I’ll tentatively and totally amateurishly get excited by this. Fingers crossed it’s a breakthrough.

Edit: missed a key paper. Edit again: so much cool stuff… Edit again: missed an important paper in the sequence

I doubt anything comes of this but people did notice.

Thank you for your work digging that up.

I will have a hard time not getting excited about this. But then, it would not be the first time, and usually this doesn’t end well for me…

On a side note, 15 Reagan appointed judges still sit on the bench. They’ve been there from 35 - 37 years. Six judges he appointed are still serving in senior status, they have served 40 years.

Can we please rethink term limits for appointed judges? Or maybe a retirement age? I have no urge to work past tomorrow let alone into my 80s unless I need to live indoors but these judges just need to get a hobby. That goes for both sides.

term limits maybe. but there’s nothing wrong with old people who - if they can do the job and want to - keep working. i hope to be old someday and would appreciate the choice

our bigger problem is all the people who can’t stop working when they need to because we don’t have a proper retirement system

I assume the lawyer knows it would not be in his best interest to respond with: you are asking me to risk death in order to present the case in this courtroom?

Have you noticed that kind of thinking more since the pandemic began?

Well, yes, in the way our leaders talk about the risks, the mortality, about people with severe illnesses, as if they’re a write-off. I am so tired of having to assert myself. What kind of world is this where we have to defend our humanity? What is valued in our society? Clearly, someone who can walk and talk and has zero comorbidities. It is an ideology, just like white supremacy. All our systems are centered around it. And so many people are discovering that they’re not believed by their doctors, and this is something that a lot of disabled and sick people have long experienced. We want to believe in this mythology that everybody’s equal. My critique is not a personal attack against Dr. Walensky; it’s about these institutions that historically devalued and excluded people. We’re just trying to say, “Your messaging is incredibly harmful; your decisions are incredibly harmful.”

Which decisions?

The overemphasis on vaccinations versus other mitigation methods. That is very harmful because people still don’t realize, yeah, there are people with chronic illnesses who are immunocompromised and have other chronic conditions who cannot get vaccinated. And this back and forth, it’s not strong or consistent about mask mandates. With omicron, there is this huge pressure to reopen schools, to reopen businesses. Why don’t we have free tests and free masks? You’re not reaching the poorest and the most vulnerable who need these things and can’t afford them.
