Hi. I've started writing a semi-weekly TB Newsletter, if you're interested in that kind of thing. Here's the second letter--about public-private partnerships, leprosy, and my forthcoming big announcement about expanding access to tuberculosis care. You'll hear more about that on Thursday. Anyway, here's the newsletter. You can sign up here.

In advance of the Big Announcement this Thursday, I made a vlogbrothers video today on how we end TB–with the comprehensive care plan often known as S-T-P, which is short for “Search, Treat, and Prevent.” But one thing I didn’t discuss in that video is the downstream benefits of comprehensive TB care.

Once you’ve hired community health workers to screen for TB, it becomes much easier to screen for other illnesses like diabetes, high blood pressure, and non-TB lung issues (especially lung cancer). TB is notoriously a disease of vicious cycles–a disease of malnutrition that makes malnutrition worse, a disease of poverty that makes poverty worse, and so on–but addressing TB can be a story of virtuous cycles: TB survivors become TB advocates, as I’ve seen with my friend Henry in Sierra Leone. More effective TB treatment leads to less stigmatization of the disease, as communities come to see the disease as curable and survivable rather than terrifying and deadly. And better access to TB care leads to a stronger overall healthcare system, because more community health workers are better connected to more primary healthcare clinics, which allows communities to better address all kinds of health problems.

Mycobacterium tuberculosis is not the only bacteria of its family that causes a lot of human suffering; there is a closely related species called mycobacterium leprae that causes the disease known as Hansen's Disease, or more commonly leprosy. There are still around 200,000 cases of leprosy diagnosed each year around the world, and while the disease is curable, it also remains–especially if not caught and treated early–a significant driver of suffering and disability in our world. 

There are many connections between TB and leprosy: Not only are the bacteria that cause these illnesses very similar, but patients have often expressed similarities in experience. TB patients who were encouraged or forced to live in sanitariums often compared themselves to lepers. One disheartening parallel between the diseases is that in both cases, those living with these illnesses are often abandoned by their families and must make new social connections within the new community of “leper” or “consumptive.” Also, both Hansen’s Disease and TB continue to exist largely because of systemic failures rather than due to a lack of knowledge or technology.

I really recommend Dr. Salmaan Keshavjee’s TED talk about how we ended TB in the U.S., and how we can end it using the same strategy around the world.

Last link from me today: I’ve been thinking a lot about the complex intersection between public and private investment (for reasons that will be clear on Thursday!) and I keep coming back to one infographic in an excellent paper (https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0256883) about the public money that was poured into the creation of the GeneXpert Machine, which can quickly and accurately test for TB. The GeneXpert machine has created a lot of profit for Danaher’s shareholders, and it has also created some societal benefit, but it could create a lot more societal benefit if it created less profit for Danaher’s shareholders. This tension seems to me one of the defining features of 21st century life. Anyway, here is the infographic:

That’s the money–over $250,000,000 of it–that came from taxpayers (mostly in the U.S. and Europe) to fund the creation of the GeneXpert Machine. And yet, this tech largely funded by the public is controlled entirely by private enterprise. I’m troubled by that model of value allocation, even if I still believe that private money and private enterprise have important roles to play in fueling innovation. But taking a quarter billion dollars of public money and then claiming total ownership over a technology, and using that ownership to deny the technology to the world’s poorest people, seems like a deeply flawed system of resource distribution to me.

I’ll see you on Thursday. I’m nervous and excited.

DFTBA,

John

Irish researchers discover underlying cause of ‘brain fog’ linked with long covid

Researchers have discovered that leaky blood vessels, together with a hyperactive immune system may be the underlying cause of brain fog in people with long covid. They suggest their discovery is important for the understanding of brain fog and cognitive decline – difficulty with thinking, memory or concentration – seen in some people with the condition. It is hoped the findings will help with the development of treatments in the future.

To Summarize:

Long Covid sufferers experience symptoms like forgetfulness and concentration issues due to leakiness in brain blood vessels, according to research findings.

Scientists from Trinity College Dublin and FutureNeuro confirm that Long Covid patients with brain fog have disrupted blood vessels in their brains, making the neurological symptoms measurable.

Blood vessel leakage in the brain, along with an overactive immune system, may be the key drivers of brain fog in Long Covid patients, leading to potential changes in understanding and treating post-viral conditions.

I can't find a single right-wing news source covering this.

In a year we’re going to look back and realize we were too hard on ourselves just like we do every year and curse ourselves for not learning the gentle hand of our grandmother and how her view of us never changed even when she saw the worst of us she still remembers we are still that sweet child she met so many years ago
