In today's superspreader/overdispersion piece by @zeynep (the best, comprehensive one on this topic to date), she also reviews how important these cheap, frequent, rapid turnaround tests can prevent such spread theatlantic.com/health/archive…@TheAtlantic
When you combine this w/ @ScienceMagazine yesterday on PCR tests (CT, cycle threshold) you realize that the testing we have today, mostly detecting infections but not infectious, are way off the mark.
We should all have had the home rapid tests months ago!
People age 70+ should not be taking aspirin at any dose for prevention. Results of randomized trials show higher risk of all-cause mortality, major bleeding events and deaths from cancer. p 153, SUPER AGERS book
President Trump takes 325 mg aspirin/day. The randomized trials tested 75-81 mg/day. His doctors recommended low-dose aspirin for heart event prevention. That recommendation is ill-founded based upon best evidence in older individuals. nejm.org/doi/full/10.10… academic.oup.com/eurheartj/arti…
As I wrote in SUPER AGERS, the immune system is the key to modulating our aging process and the opportunity to extend healthspan. Today @NatureAging 7 new articles, summarized here, that reinforce its central role nature.com/articles/s4358…
The new special issue @ScienceMagazine features Immunity with 4 outstanding review papers, 5★
Our immune system over the lifespan, sex differences, influence on physiology, and host antiviral defenses science.org/toc/science/cu…
We've learned a lot more about the principal drivers of age-related diseases in the past few weeks. And that leads to a unified model to pull it all together. (open-access)
I review 4 new reports, summarized here: 1. The proteins from senescent cells predict age-related clinical outcomes 2. A new epigenetic age clock connects the dots between aging, the immune system, inflammation and lifestyle factors 3. People with a fast pace of aging had an increased risk of cognitive impairment, age-related diseases, disability, and mortality 4. The Importance of “Immune Resilience” for Healthspan
And present a unified I/I model for what we now know
Most people haven’t heard of this test, which is available in the US. It accurately predicts Alzheimer’s (not just if there’s a risk, but when). It is favorably affected by exercise and likely many other lifestyle factors.
Here’s (almost) everything we know about it. In Ground Truths (link in my profile d/t X-suppression)
A major @Nature paper this week found a significant decline in dementia after an outdated Shingles vaccine.
I've reviewed the study and many other relevant ones in a new Ground Truths (link in profile)
A Table from the post
The effect in the 2 natural experiments differed substantially by sex with the benefit predominant in women
