What I would add to the standard blog model

The combination of RSS and the basic blog post is almost perfect. There are, however, a few things that would make them even better as a way to share information in most organizations.

1. Provide an email summary option that is generated on post, daily, or weekly. (SharePoint does this for some list types.)
2. Add a Publication Date in addition to the Last Modified date and make the Publication Date both the primary sort field and make it user editable without changing the URL. That way a publisher can choose to easily replace a topical post with a newer version and optionally republish it as new. (For organizational use the historical record is unimportant.)
3. Author control of notification generation. There's no need to generate a fresh RSS entry or email update for the correction of a few typos or other minor changes.
4. Easy sharing of articles by email and other 'send' modalities.
5. Tags with tag specific rss and views (many blogs do this).
6. Editing tags should not generate notifications.

That's all. No comments -- in practice I think these can occur elsewhere.

PS. It looks like Blogger has broken tags/labels as of today! So this post has none.

Electric vehicles will end another non-college job - the auto mechanic

 My Great-Aunt was born in the 19th century. She spent most of her life working in data processing. She, and thousands like her, did read, delete, update operations on paper cards that were passed between thousands of small rectangular desks in a large rectangular building in Montreal. None of her coworkers had a college degree -- I suspect many could not read very well. The work seems impossibly dull, but she enjoyed it and the pension it brought her.

I have one of those desks, I'm typing on it now. It fits nicely in a corner of my living room, and I'm slender enough to fit comfortably in it.

By the 1960s the first business computers wiped out her industry as definitively as the automobile eliminated millions of horses. There would never again be a large scale job that required no particular social, physical, or cognitive skills.

Since that time IT has generated vast numbers of knowledge worker jobs that pay relatively well while eliminating jobs that do not require cognitive skills.

Now electric vehicles are going to do the same thing. Compared to internal combustion engines they are much easier to maintain; their complexity is in batteries and software. Never-college auto mechanics are going to lose their jobs.

There's a lot we can do about this problem. It's not only the right thing to do, it's also essential to our survival. Even if Biden wins in 2020, if his administration doesn't act quickly there will be another Trump in 2024.

State of the COVID-19 Pandemic - Fall 2020

I've written only a few COVID-19 posts, mostly about masks and activities. Looking back at them today they hold up pretty well. This feels like the right time for a summary.

Obviously the American response has been pretty lousy. Given America's fissiparous culture and lousy record on things like managing gun violence and providing universal good-enough healthcare we were never going to do a terrific job, but Trump took us down a few more levels. The GOP's anti-science and anti-government stance has contributed as well, not least by underfunding the CDC for decades. It does suck that the disease is infectious before symptoms develop.

We will probably get a decent vaccine. Even if Trump, Xi, and Putin screw-up their national evaluations there will be a few nations that do it right. We probably won't get a great early treatment antiviral in the next year or two but our hospital management will keep incrementally improving and we ought to get a decent monoclonal. We are, despite America's almost incomprehensible incompetence, starting to see better masks in use. Masks that protect the wearer as much as they reduce spread. (We could have lightweight PAPRs for use by vulnerable teachers, but that's like asking for a warp drive.) We should get inexpensive antigen tests for use in school and home, and we'll probably figure out how to use them.

Our understanding of the American pandemic is not great. Data is getting harder to find for many states. That won't change unless Trump loses -- and even then it will take months to rebuilt. A few states may have good data collection so we will have to rely on them to sample pandemic progress. Universities and non-profits are trying to close the gap. Getting local prevalence data in Google Maps will help. There's still a chance states will adopt Google/Apple contact tracing (paging Minnesota, damnit).

On the bright side our knowledge of the innate immune system and of viral infection sequelae (myocarditis [1]!) is growing ten times faster than normal. Even in the QAnon world we can still do some science.

On the public front the situation is mixed at best. It will be a miracle if we don't see a big rise in numbers as winter settles in and we move indoors. Pandemic social and economic distress is amplified by the longterm issues of never-college income, information technology disruption, demographic shifts, and the legacies of American slavery. Remote work has been pretty successful though -- getting people out of air conditioned offices is a big deal.

Less unhappily, unknown sequelae aside, the vast majority of people under 40 with good innate immune systems seem to tolerate SARS-CoV-2 pretty well (though some will die horribly after months of struggle and the myocarditis thing is a bit worrisome). It also seems that a modest amount of ventilation dramatically reduces infectivity -- and, despite lack of public guidance and Trump's CDC sabotage, I think ventilation is improving. There don't seem to be big outbreaks in gyms or ice arenas for example -- though there's also no useful data. COVID-19 will become endemic, but over decades, as we develop true herd immunity, it will become more like the other coronavirae that we live with.

Between our various failures, residual strengths, and the peculiarities of COVID-19 much of America is more-or-less implementing some version of slow motion infection of the under 30 and more-or-less leaving the 40+ to protect themselves. The elite 40+ segment of Americans are learning to buy and wear user-protective masks, the non-elite are kind of screwed. But that's America in the year 2020.

[1] Lots of people are wondering how common myocarditis is with viral infections. We've always known of viral myocarditis, but it's not like we did cardiac MRIs on everyone with a cold. The decrease in MIs during COVID precautions is certainly interesting. This review isn't perfect, but it's a good start.

FDA "approved" KN95 masks available on Amazon - $4 each

In my various explorations of next-level masks I found this one on Amazon (Via Rolling Stone, the acting public health division of the US government [1]):

https://www.amazon.com/Powecom-Protective-Non-Medical-Efficiency-Authorized/dp/B087M2T7NP

Currently $4/each with Prime. That price is typical for next level masks, prices are falling fairly quickly though.

Powecom shows up on the FDA n95 alternative list: Appendix A: Authorized Imported, Non-NIOSH Approved Respirators Manufactured in China (Updated: August 14, 2020) as Guangzhou Powecom Labor Insurance Supplies Co., LTD

We keep these for higher risk situations, such as visiting people even older than us (apparently they exist) or taking a drive share ride.

I think availability is rising quickly and prices are falling, I expect they'll drop below $3/mask in the next  few weeks.

After months of seeking better masks we are now getting the sort of thing China has had since January. We are learning about our options not from the failed American state, but through the efforts of the last remnants of American journalism.

MAGA.

[1] Contrary to this article physicians reuse N95s. We wear them one day, leave them in a hot dry place for a week, and wear them again.

COVID Cancellation: The fight with Delta from May 1 to Aug 20, 2020

The COVID battle with Delta

1. May 1, 2020: Delta canceled a flight for daughter and I to Korea. I spoke with the Delta rep and was told we'd receive a full refund. But trouble was already brewing.
2. We were in Delta database for refund until, one day, we were not.
3. We sent complaints to DOT, MN Attorney General, and American Express
4. July 11, 200: American Express responded to our objection and refunded two tickets.
5. DOT said they'd referred our complaint back to Delta.
6. Delta refunded ONE ticket
7. American Express reversed their refund on both tickets. I tried to appeal but the appeal process said I had to phone (which is very hard to do on my schedule).
8. I replied to the DOT and Delta/DOT email addresses that one ticket remained. 
9. I was unable to get more help from AMEX. 
10. Aug 20, 2020: Delta notified a second refund and a few days later it was in my AMEX account.

There are class action suits against Delta and other airlines. Our struggle went on for almost 4 months.

My guess is Delta was managing its cash flow by paying its debts slowly. I suspect high mileage customers with flight insurance received early refunds -- because Delta knows the insurance companies would go after them. Then high mileage customers and major business buyers. After that it's who complains the most and longest. 

Delta fought payment pretty hard. I though it was over in July when AMEX refunded us, but I saw the paperwork Delta sent AMEX. They really didn't want to pay. 

In the end I think the DOT complaint did the trick. I never heard from the MN state attorney general.

I hope the class action suits succeed.

Curbsider CME for non-internists through VCU Health

My favorite CME source, the Curbsider's Podcast, has long offered CME credit for internists (they are, after all, an internal medicine podcast). For family physicians, not so much.

There is now to get free Category One AMA credit [2] for Curbsiders podcasts through "Virginia Commonwealth University's VCUHealth Continuing Education [1] using their Curbsider curriculum.

You have to listen to the episode and complete a post-test. You can and should use the Podcast notes to compete the post-test (how we learn). 

I was able to register with VCUHealth although I have no connection there. After registration I completed my profile. (The web site is ancient and barely works in a modern browser -- don't try it on mobile.)

This is all a bit of a secret. I only know of it from a blurb at the start of recent podcasts. There's a tiny CME link to VCUHealth at the bottom of the summary page for recent episodes.

I've completed one module. There were 3 post-test question, one didn't have a clear answer (practice varies). On answering all 3 "correctly" I received a certificate. I had to answer some annoying 'commitment to change' survey questions that must be part of a (past? forgotten?) VCUHealth initiative. I received a link to an AMA PRA category one certificate that I downloaded, then I entered the CME at the ABFM site (they had entries for VCU).

A happy discovery. Thank you VCU and Curbsiders.

- fn -

[1] Starting from the CME site, it was weirdly hard to figure out what the heck VCU is. The logo is really small and the full name is never used.

[2] To be a AAFP fellow you need AAFP CME, but the American Board of Family Medicine accepts AMA Category one and their own programs. The two organizations don't entirely get along. 

Update 5/1/2023: I once completed a "knowledge feast" CME from the Curbsiders that spanned multiple episodes and was very (maybe too) time efficient. I believe that was a one time thing -- too easy to misuse I fear.

Viktor Frankl - on expectations and the behavior of people

Viktor Frankl formed some of his opinions of human nature by surviving several concentration camps. After his release, in a few days, he wrote a book about his experience - Man's Search for Meaning.

The book has harsh critics. I read it and I think much of sees truth, though it also a book of another era -- an era in which "man" more or less included women. 

Today psychology, psychiatry, neurology and the sciences retain little of Frankl's life work. He could not grasp that meaning might exist in the absence of religion, or that responsibility could be assumed rather than fundamental. I believe, however, that he had a true understanding of the extremes of human nature for evil and for good.

YouTube (and the Ted site) have a video of a lecture he gave later in his life. From the Frankl Institute (with let another video copy!):

YOUTH IN SEARCH OF MEANING, 1972 [4:22]

Frankl speaking at the "Toronto Youth Corps" in 1972. See Frankl "at his best" as he vividly explains his theories, and even draws analogies to piloting an aircraft – a passion he had recently picked up.

In this lecture he talks about how one must "crab" an airplane to adjust for a crosswind (1:45).  To reach a destination you have to periodically turn into the wind. He expands the analogy to people:

If we take man as he really is we make him worse. But if we overestimate him ... if we seem to be idealist and are overestimating ... overrating man ... and looking at him up high ... we promote him to what he really can be...

... Do you know who has said this? If we take man as he is we make him worse, but if we take man as he should be we make him capable of becoming what he can be? ... This was not me. This was not my flight instructor. This was Goethe.

From this it is a small Google step to the Goethe quote (in English):

When we treat man as he is we make him worse than he is.

When we treat him as if he already was what he potentially could be we make him what he should be.

 In the strange time of June 2020 I think this is worth remembering.

The mask we need

What do we believe now?

We think that coronavirus is moderately contagious and is spread primarily from person to person rather than by surfaces to person. We think the best way to get COVID-19 is to join an indoor dance and singing session and that outdoor spread is rare. We think indoor masks are valuable and outdoor masks are primarily social gestures. We think cloth masks work primarily by reducing spread from someone with early COVID-19 and minimal symptoms. As of today there's a suggestion that children get mild COVID-19 infections but don't spread them well.

We believe social distancing reduces spread but has a terrible economic cost that falls primarily on non-college workers and small business owners.

We believe effective therapies will emerge gradually over the next 4-18 months and effective vaccines over the next 6-18 months.

So what could we do now that would reduce infection, possibly suppress disease, and allow the economy to reopen?

We should test and trace of course, but given the state of American government and American media (Fox, Murdoch, etc) that's unlikely to be enough.

So what else could we do that doesn't require new technology or new innovation?

We could give every adult a better indoor mask. A mask that gives bidirectional protection, that protects against both infection and transmission. Give it first to 70+, then 60+, then every adult.

What are the features of this mask?

It's reusable of course. Washable with a filter module that's easy to replace. It comes with a UV light sterilizer than can hold several masks. It's a high air flow mask; you can wear it to your indoor CrossFit speakeasy and get your deadlifts done. It's not medical grade, but it's a hell of a lot better than a surgical mask.

If you're going to wear a damned indoor mask, it should work.

This doesn't require new science. It doesn't require new technology. It doesn't require closing the economy. At $100 a unit we could give every American adult this mask and a family UV sterilization unit for 30 billion dollars.

30 billion dollars. That's nothing. Jeff Bezos could do it from his change pocket.

Want to restart the economy?

Make this mask.

Wearing a cloth mask outdoors is like wearing a helmet in your car

I wrote this first on Twitter:

Outdoor masking is the equivalent of wearing a helmet in your car. Indoor masking is the equivalent of wearing a seatbelt in your car... 

 ... Formula 1 drivers wear helmets in their cars. Makes sense for them. For rest of us net gain is just background risk noise... 

... It took decades of struggle to get Americans to use seatbelts. Even now some don’t. Despite overwhelming value... 

... If you get hung up on wearing helmets in cars people will think you are nuts and ignore the seatbelts.

The best science I've seen on outdoor communication is the Chinese tracing analysis. We aren't going to see much more science -- experts consider the risk too low to be worth researching given all we don't know about indoor transmission (including transit).

There are two valid objections I know of to this stance:

1. Outdoor masking is of low value but it helps set social expectations that make indoor masking acceptable.
2. If you don't wear a helmet in your car the risk is on you, if you don't wear a mask outside the risk is on me.

To which I would say - True. But ...

1. We would never have gotten seatbelts in cars (high value) if we'd insisted that helmets were equally important (much lower value). If we don't have science we have nothing against the forces of stupidity.
2. Yeah, that does suck. Happily the risk to you is extremely low. As a matter of politeness we should give anyone wearing an outdoor mask a 10 foot space. It's a signal of strong personal concern.

Outdoor masking has a cost beyond damaging expert credibility. It's very uncomfortable to exercise wearing a cloth mask. The physical and mental health benefits of exercise dwarf the non-existent value of the outdoor cloth mask.

Indoor masking is where we should be putting our energy. We should be developing N95 equivalent reusable masks for at risk persons to wear indoors in place of the cloth masks most of us wear.

True story. My father, who was a geek before his time, specced seatbelts on his 1950s company car (to the chagrin of his boss no doubt). They came as 4 point restraints. When he showed up in the car for a date his guest refused to enter the car. Anyone with seatbelts in the car must drive like a maniac.

PS. Regarding those "outdoor plume" studies --- viral reproduction does not scale with respiration. That is, if you breathe 3 times as much you don't exhale 3 times as many viruses.

The year ahead

Massachusetts is going to try the Wuhan/South Korea path. Or something like it.

What's the alternative?

1. Shut down and open up -- trying to stay under healthcare capacity.
2. Buy time to find meds that work a bit, better care approaches for outpatient, hospital, ICU. There are some that look promising now (not HCQ).
3. Buy time to build up manufacturing, supply chains, new jobs in COVID-19 care and management, serology that actually works.
4. In a year or two we have some vaccines that work like those developed for animal COVID.
5. COVID becomes a second yearly severe flu, worse than the Swine flu. On top of the traditional flu.
6. We have fewer people over 80.
7. Many countries will stop Americans from visiting.

In Minnesota we'll let Georgia make the mistakes. If Massachusetts succeeds we'll try that.

Sentinel surveillance for COVID-19: nasal swabs of teachers, service workers, gym coaches and healthcare workers

Sentinel surveillance in pandemic control is typically based on identifying health care delivery sites that get intensive monitoring.

I have been wondering about how we'd do surveillance when we move away from our current stay-at-home condition. Assuming we use self-administered nasal swabs rather than obnoxious nasopharyngeal swaps we could distribute volumes of mail-in test kits (goal of 24h turnaround) to school teachers, healthcare workers, gym coaches, bartenders, and so on. Volunteers would swab weekly, mail in kit with their bar code on them.

We'd need a few million kits per week to do this.

Happily, this is discussed in the April 7 paper by McClellan, Gottlie, et al. I'd heard of the paper, I just needed to read it.

So I don't need to worry ... it's taken care of.

It's just the flu

When contrarians compare COVID-19 to influenza, they invariably mean to minimize it's significance. From what we know now this seems absurd, but of course it's not so simple.  The 1918 pandemic, after all, was just the flu -- and we don't think that's the worst influenza can be.

So how does COVID-19 compare to the spectrum of influenza? Wikipedia has an article on the CDC pandemic severity index that ranks various influenza pandemics. The 1918 pandemic was Category 5 - a case fatality rate (CFR) of 2.0% or higher. The worst influenza in my life was the Hong Kong flu with a CFR below 0.5%. It is said to have killed a million people worldwide (out of 3 billion).

The COVID-10 CFR seems to fit that range. We think its CFR is somewhere between 0.7% (based on presumed cases) and 1.5% (based on excess mortality). So by CFR it is arguably "just the flu".

What about if we look at the other half of the equation - the Basic reproduction number (R0 how contagious a disease is)? Wikipedia is again helpful; influenza ranges from 0.9 to 2.8, the early estimates for COVID-19 the 1.4 to 3.9. So COVID-19 fits the influenza model there as well, as long as we include monster events that cause historic devastation.

We can also look at who dies, and the disability of those who survive. Some influenza takes the young, some take the middle-aged, most take the old. COVID-19 seems to go for the middle-aged and old, so again flu like. As to disability, I haven't seen any reports on post-influenza disability.  I wonder if persistent lung damage will be one way that COVID-19 is not flu like. We don't know yet.

So, yeah, COVID-19 mostly fits within the spectrum of influenza, as long as we include pandemics that hit every 100 years or so. It's "just the flu," in the same sense that WW I was "just a war".

Hydroxychloroquine, COVID-19, and Lupus

Researchers are taking seriously the use of hydroxychloroquine for COVID-19 therapy:

Both chloroquine and hydroxychloroquine inhibit SARS-CoV-2 in vitro, although hydroxychloroquine appears to have more potent antiviral activity [75].

I think saw a post somewhere that claimed it interferes with viral replication inside infected lung tissue but I can't find it now.

That's obviously great if it works out.

If it does work out though, it might be worth looking again at old (and still current) ideas that rheumatic disorders that response to hydroxychloroquine (esp. SLE, RA) are infectious in origin. Maybe an RNA virus ...

Exercise and sanity in the time of you-know-what

Fellow exercise addicts -- let's examine our options...

1. Trail, road, gravel biking. Extreme aerosol diffusion. Antiviral ultraviolet radiation built in. Social distance built in. Definite good. Buy your gravel bike now before they're all gone, but any road bike will do. Start commuting by bike.
2. Mountain biking. Same, but different bike.
3. Running. Hard to be less social. Trail runs nicer. For St Paul MN -- Battle Creek!
4. Garage Gym. Get that car out of there. Who cares about cars anyway? Bench, bar, weights, programming from your local CrossFit franchise. Get some friends together at a distance (byob).
5. Your local CrossFit ... class sizes will be smallish. Open the big doors and spread outside where the air flow is amazing. Dress for the occasion. Learn to love open air deadlift and those $!$^@ runs and rows and such.
6. Golf. Chase (Tim) wants this. Lots of social distance! Don't share clubs :-).
7. Lake swimming. Cold in MN March, but eventually ...
8. Inline Skating! Time for a comeback. Get those blades out of the attic. Airflow, etc. Join the Facebook Minnesota Inline Skate Club Group.
9. Hiking. Slow trail running for the win.
10. Rock climbing outdoors. Sweat and blood do not transmit. Maybe don't spit on the rope?
11. Paddling! Canoe, Kayak -- air flow, social distancing, perfect.
12. Fishing -- not much exercise, but good for sanity.
13. Tennis -- don't spit on the ball.

Things governments should do to help morale:

1. Free fishing licenses!
2. Waive state park fees.

COVID-03 and COVID-19: influenza co-infection and multiple strains

I remember COVID-03 (Coronavirus disease 2003, known then as SARS) caused by Novel Coronavirus 1 (SARS-CoV-1). It was frightening and puzzling, especially in Toronto Canada (from 11/2003, emphases mine):

The entire SARS story puzzles the heck out of me. Why did so many nurses die, even in locations that should have had strong infection control? Why did the disease seem so contagious in some places, and not at all contagious in others? Did the virus attenuate? Was the epidemiologic behavior due to an unidentified cofactor infection that was common in some places and not in others? (eg. a second virus was needed to develop full fledged SARS).  

I can't believe that the infection control measures were so effective. The disease was loose in China for months. Why did it not spread in India at all?

A year later I wondered if there were multiple strains circulating, all mutually immunogenic, some more toxic than others. (There may be multiple strains of SARS-CoV-2 as well.) I wondered if that suggested a pandemic management strategy - a kind of "backburning"...

Create a contagious synthetic pathogen that's relatively benign, but induces immunity to the major pathogen -- and spread it actively. I say not entirely novel, because this is how Polio was suppressed. The oral vaccine was an active contagious pathogen that was excreted in stool. It immunized a vast number of persons -- but some became sick, disabled, or dead. When Polio was less of a threat we switched to a non-pathogenic inoculation. The difference is the successful Polio strategy was probably unintentional (I suspect some people understood even in the 1950s), but in the future we'd be deliberately exposing an entire population to an immunogenic pathogen that would almost certainly harm many people.

Now we are enjoying COVID-19, the bigger, uglier, brother. Again there's tremendous variability from place to place and time to time. Again India seems unbothered. Again young healthcare workers are vulnerable. Again I wonder if some of the sickest patients have multiple viral inflections or more aggressive strains. Perhaps as our seasonal flu finally fades so will the worst of COVID-19.

I hope this time we'll understand it better.
