This study is HUGE FOR YOU!

Why? Every hospital, dental, and nursing home corporation around the world use studies designed by the Mark Loeb Group to keep N95s off of your HCW.

As they bend over you in a mask so baggy you can see their toothy smile.

Let me ask you...

/1
Would pulling on an N95 protect you more from airborne anthrax than if you pulled on a medical mask (MM)? From only 3 feet away?

In fact, IT IS AGAINST the proper use of respirators.

OSHA would have you KICKED off the job site.

But when Loeb did it in 2022? The $$$ 🎉🎉🎉
But - once this preprint is published? I do not see how Loeb (2022) is not RETRACTED.🔥🔥🔥

That study compared surgical masks to N95s. It said that surgical (medical) masks are as good as N95s in protection from Covid.

That they are not inferior, aka noninferior, to N95s.
And this stone-cold evisceration of the Loeb group who richly deserve it?

Is a thing of savage beauty.

Starting with - how do you not get infected 3 feet away from some feverish (febrile) C0Vid infected?

(Plus, the 58% asymptomatic transmissions? )
Image

But Loeb's group said, "No way, man. Our people were rolling strapped! From the parking lot to the parking lot." (Universal masking***).

Now, this is where it gets good.

Someone👇 confirmed with a Loeb study member that the N95 group could use medical masks in hallways.
Post-hoc assertions that the trial was carried out with all subjects in the N95 arm wearing their PPE continuously are unsupported by evidence: The claim is not supported by prospectively registered information;(65–67) The claim is not consistent with the initial study protocol;(64) The study ended March 29th, 2022, yet the modified statistical analysis plan dated February 17th, 2022 and the modified protocol dated March 1st 2022(64) both specify that subgroup analyses would include sites with and without universal masking; Despite being fundamental to the interpretation of the trial result...
Dr. Lynora Saxinger MD FRCPC Infectious Diseases @AntibioticDoc · Dec 2, 2022 **So it’s all gotten a bit leggy but if you are entering here I did confirm and need to clarify continuous masking didn’t have to be assigned mask so N95 group could use medical masks in hallways etc so is not a “all shift” N95 which is what I’d understood from a studymember
And the people in medical masks could wear N95s anytime they wanted.

Got it? This supposedly very methodological study has people switching anytime they wanted. Participants in the MM arm were allowed to wear N95 at any time based on point of care risk assessment.(58) Considering that the most COVID-cautious participants would have had both the greatest motivation to report and seek treatment for suspected infection; and to take advantage of the opportunity to wear N95 if assigned to the MM arm, it would be expected that these factors would interact to further artefactually reduce cases recorded in the MM arm.
And their OWN PLAN said they would have sites with and without universal masking.

Until they changed it after the fact.

AFTER THE FACT! Can we trust them? Surely they have no incentive to lie like rugs, right?

No UNREPORTED conflicts of interests like 7 million dead.

The claim is not consistent with the initial study protocol;(64) The study ended March 29th, 2022, yet the modified statistical analysis plan dated February 17th, 2022 and the modified protocol dated March 1st 2022(64) both specify that subgroup analyses would include sites with and without universal masking;
As noted above, the trial was explicitly designed around an inappropriate intermittent-use protocol – a fatal flaw from which unregistered protocol modifications and coincidental universal use are claimed to have salvaged it. Retroactive insertion into the registry with back-dating to the beginning of the trial (a repudiation of the purpose of trial registration) does not provide the evidence such claims require.
Unreported conflicts of interest As discussed above, COVID is known to be substantially airborne, transmitted in infectious bioaerosols.(3) Anticipated in the earliest days of the pandemic, this danger was overlooked by policy makers at great cost(2) - a “…very big mistake” where better decisions “…would have saved an enormous number of lives”.(116) Seven million deaths have now been officially attributed directly to COVID, with the real total estimated at 27 million(117) and possibly much higher,(118) and millions more suffer long-term impacts from Post Covid Condition (PCC).(119–123) Any ...
No conflicts of interest at all, like 16 study members running IPC at their hospital. No pressure from needing to be proved right. No pressure to keep costs low as N95s are spendy!

None like testifying at a trial to deny nurses N95s. With 5 study members.
Sixteen of the authors as well as two of the three members of the Data Safety and Monitoring Board (DSMB) hold Medical Director of Infection Control (MDIC) or similar positions at their respective institutions (Table 1). Of these, nine (including the DSMB Chair) are located in the province of Ontario, where in 2021 the Ontario Nurses’ Association requested judicial review of hospital infection control policies they asserted were dangerously inadequate in failing to provide for universal use of N95 respirators.(100,127) Similar positions regarding SARS-CoV-2 mitigations had been taken nation...
Endorsed shortly before the end of data collection for the Loeb trial in Canada, the affidavit also included the statement: “…our experience at my hospital and other healthcare facilities throughout Canada where use of medical mask and eye protection alone to care for an unmasked patient with unrecognized COVID- 19, has not resulted in transmission to healthcare workers.”(127) It is unclear how the members of the DSMB reconciled endorsing this statement as accurate with the then-current trial data they were responsible for being aware of, showing multiple infections in healthcare workers we...
None like running THE group that the WORLD listened to for a year of death. Or being a member. Senior author Dr. Conly chairs the WHO Infection Prevention and Control Research and Development Expert Group for COVID-19 (WHO-C19-EG – of which Dr. Loeb was also a member),(131) upon whose advice the WHO’s position on COVID prevention was largely based in the first year of the pandemic.(132) This group had publicly argued against the need to adopt “…the precautionary principle with consequent use of particulate respirators instead of medical masks as a component of PPE for routine care of COVID- 19 patients…” in August 2020,(125) despite previously receiving direct warnings to the contrar...
No, when the study was abruptly moved from Canada to Egypt, Israel, Pakistan, just as clear evidence was emerging that N95s were better than MM? Nothing suspicious.

And Egypt ending up being the location for finding surgical masks are the same as N95s?
When the study was terminated at all sites in the prospectively registered countries, the results showed clear evidence of a result opposite to the primary published finding, showing medical masks very likely provided substantially reduced protection against a pathogen with potential to cause death or serious harm.
The reported finding of noninferiority is entirely an artefact of the data from sites in Egypt, and cannot be obtained without them even if we were to accept all other alterations to the trial as legitimate.
Nothing against Egypt, it's just where serious issues with women being forced to work, men in N95s, bad ventilation, public transportation in the middle of the first Omicron wave, all caused that effect.

Although... The omission of site information from the published information and the trial registry is particularly relevant in Egypt, as only one of the six sites was equipped with an HVAC system (in contrast to 100% of sites elsewhere, per Supplement Table 11),(58) with the other five provided only with “…a combination of air conditioning and outdoor air”. Without further information this could mean simply openable windows and some recirculating air conditioners, which would tend to encourage closing of the windows while providing essentially no air cleaning – the worst combination possible in the pre...
The actual data collected was sketch AF. "Perfectly excluded" is not a good phrase to hear about your study.

You been busted, son! Is a rough translation. The pattern observed in the data reported by Loeb and colleagues appears highly unlikely (p<0.006) to occur naturally in data collected as described in the publication.
Nothing like a few changes to a study👇. Between 16 IPC directors, you'd think they'd kick all kinds of study a$$, instead of needing midstream changes.

There is more, but I am tired of reading about the Canadian IPC Mafia.

They are very bad people who did a very bad study. Image
That should be retracted!

They did it! Called for retraction!



/Continued with some thoughts. acpjournals.org/doi/full/10.73…
Image
Actual care exposure time to patients in Egypt was about double (very important, not mentioned)?

It has all the outbreaks (mentioned in the study)
Image
Image
One factor everyone seems to have missed? Maybe I just didn't see it?

Extended use AND re-use of the N95s does not seem to have been factored in.

Fit failure is a huge issue.👇

Loeb does a self-own on this in commenting on his own study.

Universal masking was not fully explained in the study.

Parking lot to parking lot?

UM in Egypt, Pakistan, Canada - might be all different.

For example, Japan, this hospital had universal masking, but not in break rooms. Led to infections.

Pakistani where PATIENTS did not adhere to universal masking (UM), despite beng requird to.

Obviously, patients are aerosol src. Also, the antimaskers at the Loeb group included ACH at the various places. THAT IS NOT MEASURED ACH. There is a
researchgate.net/profile/Saerah…
huge difference - if you ask someone actually experienced with aerosols.

Changing rooms in hospitals - we have no idea of the Egypt set up.


We do know Egyptian HCWs are pretty good at masking up at work. Not in public.

Loeb (2022), truly one of the worst studies ever. Giving Walach a run for his money.
My apologies, I forgot to link to the top of the thread for your convenience!

Thank you for getting to here and now knowing how the latest masking RCT is fatally flawed.

The other two main ones are also flawed in the main same way. 3 feet.

If you are Covid Aware you have probably been avoiding the dentist. Well, the dental studies have come to you.

This edition? #CovidAwareSoReducingDentalVisits - Water flossing (WF) edition.

Or, as I like to think of it, the Gum Salon.

Thread.
Flossing is necessary for those super tight contact points as you see in the above thread, and is great to remove plaque down 1 mm deep in the gum line (gently).

InterDental Brushes are fantastic and go down 2-3 mm into the gum line to remove plaque.

And WFs in general, are, well, amazing!!

They basically go back and forth with InterDental Brushes on which is better as far as being the top of the food chain for overall cleaning of the space between your teeth.

But.

If you have gum recession, you may have this Image

#CovidAwareSoReducingDentalVisits - less mouth open = less 'vid risk.

I am a GREAT flosser. My family thought we had genetic gum disease.

Below we can see rubber stick on the left, floss on the right, and a InterDental Brush (IDB) in the middle.

See the problem?
/1 Image
A couple more example pics on why I am sick to my stomach thinking of all that money wasted.

We THOUGHT we had great dentists. Not a single one mentioned IDBs, and how the bristles allow all interdental spaces to be reached.

And it gets better!

/2 Image
Image
IDBs actually reach down in between the gum and teeth - 2-3 mm. Floss? Only 1-2 mm.

As plaque grows down into and touches your gums, that's what causes them to get inflamed - and begin to retreat (very simplified).

If you brush that space? Problem solved.

/3 Floss, Interdental Brushes, and Waterpics Use all of them - floss works great for those narrow spaces. Interdental Brushes (IDB) work great in larger spaces. Waterpics work great immediately after eating, as you want to wait for an hour eating acidic/sweet just like regular brushing. It is a mistake to NOT IDB. Multiple studies indicate IDB is good, including this RCT where IDB was better than flossing (free version - great how to brush) - with people with chronic periodontitis. Students found IDB to be better. But IDB is better than rubber picks is better than floss. IDB way better ...

Covid Aware Teeth

The Calcium Lactate Rinse. Cheap, super easy to do - and it really enhances your fluoride uptake to re-enamel your enamel.

It's just not very well known, despite being very well supported within studies - and very cheap.

Mix 1/8 tsp with 1 oz water. Shake
thoroughly, till the granules disappear. Takes a few or 20 shakes, then just wait. Rinse for 1 minute. Spit out.

Immediately brush with fluoride or fluoride rinse.

There might be a better powder

I use the same 1 oz shaker as my stannous fluoride rinse comes in.

(That fluoride rinse was $4 cheaper at my dentist than this $24.

My Prevident 5000 ppm actually did not need a prescription - if bought from my dentist, as a couple of side notes.)

.On the one hand, we have study after study showing 36% or so rate of LongCovid.

On the other, we have the WHO saying the rate of LongCovid is only 6%.

I got curious. What drugs are the WHO smoking - and can I get some?

🧵. Image
My 36% comes from the latest massive meta:
eatg.org/hiv-news/more-…

But what about that 6%?

Turns out it's this old chestnut from 2022.

And there are such major players on it...so many I can't even screenshot them all.

But I fear no title - and neither

jamanetwork.com/journals/jama/… Image
will you.

The problem with this 6%? There are 200+ symptoms in the LongCovid symptoms constellation.

This study focuses on three clusters.

Which is incredibly vague, which is normal for the WHO.

So, after digging through the f***ing supplement, there are a few symptoms Image

COVID is as transmissible as measles?!

"BUT, BUT, measles can infect up to 90% of people they are in contact with!"

So can COVID.

Time to wake up. The lecturer tried to promote sales of a flax oil product, and many elderly people were lured to attend by the promise of free eggs, Xinhua News Agency reported. He gave three lectures on Jan 10 and 11 in a Tonghua classroom while not wearing a mask, with each lecture lasting about 2.5 hours. A total of 97 people, most of them retirees, attended the lectures in a classroom whose doors and windows were closed, the China CDC report said. The lecturer went to a pharmacy at noon on Jan 10 due to muscle pain and other symptoms, indicating he was likely at an early stage of the disease then, it ...

So, some will be pushing back - always welcome, albeit this is anticipated.

Rnaught is just an estimate.

The famous measles 12-18 is shown below.

But the R0 of 6-8 has the most estimates.

Remember THAT scene from Outbreak with Dustin Hoffman - "It's Airborne." ?

SARS-COV-2 is airborne via HVAC. Just like TB is - but it is way more contagious.

Still no panic, right? We know how to be safe.

Motel 6, or AirBNB - no shared HVAC, is best.

But HOW do we know?

🧵
A recent study in South Africa used Syrian Hamsters to duplicate the study that finally convinced everyone that TB was airborne.

The TB study is interesting because the military vets in VA hospitals were getting infected disproportionately.

So, they used HVAC ducting to In 1956, tuberculosis was a major global killer, and it disproportionately affected military veterans hospitalized in the Veterans Administration hospital system. Then, as now with COVID-19, epidemiologists held that tuberculosis and other respiratory diseases were spread by large infected droplets through person-to-person contact or contaminated surfaces. But Richard L. Riley, an expert on lung physiology at the then Johns Hopkins School of Hygiene and Public Health, and his mentor, William F. Wells, had identified another possible mode of transmission.
connect a 6 room TB ward to 150 guinea pigs.

Of those 150, only 3 PER MONTH got infected.

Illustrating that TRANSMISSIBILITY is just a CLUE to if something is airborne.

Dr. Riley went on to patent UVC tech, and develop the Wells-Riley equation which is so important in airborne Atop the Baltimore VA Hospital, they constructed an air-tight closed ventilation system that connected a six-room tuberculosis ward to an exposure chamber with 150 guinea pigs. (Among rodent animal models, only guinea pigs could cough and sneeze, making them ideal for studying how respiratory diseases spread.) The guinea pigs were exposed to the infected air over a four-year period. A second group of 150 guinea pigs acted as controls: their air ducts were irradiated with UV-C lamps to kill TB bacilli.
In the test group, an average of three guinea pigs per month contracted TB, while no controls were infected. The experiment not only proved the airborne disease transmission of tuberculosis for the first time, but also quantified how many TB infections could be expected to result from exposure to a given number of patients over a defined interval.
The insights from the Baltimore VA Hospital studies were later used to develop the Wells-Riley equation, which quantifies infection risk and informs strategies to ensure staff and patient safety in contagious clinical environments. The model can also calculate the risks of transmission for airborne infections on planes and trains, in prisons, and in other public and institutional spaces. As chair of the Department of Environmental Medicine from 1960 to 1977, Riley warned that the danger of infection from airborne diseases was increasing as people spent more time indoors and air conditionin...
