Covid-19 Reuters Q & A with William Haseltine
I live-tweeted a fascinating and perhaps rather depressing meeting with William Haseltine via a Reuters Newsmaker Broadcast. His talk was upbeat but the message does not offer a positive outlook unless we can collaborate internationally to identify, trace, and isolate and go back to early antivirals to treat people urgently. A vaccine will probably never be found, we must stay on top of this virus when we get communities under control. Moreover, we must recognise that another emergent pathogen could appear any time. These are essentially my notes from Haseltines’s talk. Might we ever achieve herd immunity? There is n...

Better Vaccines for Older People are a Poor Alternative to Better Immune Systems for Older People
The paper here offers a good overview of recent research and development aimed at improving the effectiveness of vaccines in old people. Vaccines are only poorly effective in the old because of the age-related decline of the immune system. A great deal of effort, with only some success, has gone into trying to improve vaccine effectiveness in older populations. Even if tinkering with vaccines boosts the percentage of patients who exhibit an immune response, however, that response is always going to be more anemic than that of a younger person, given the effects of aging on the immune system. This time and funding would per...

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

New Norms And Difficult Dogs: The Week ’s Best Psychology Links
Our weekly round-up of the best psychology coverage from elsewhere on the web Sharing the content of your dreams with others can improve your relationships and increase your empathy levels, write Mark Blagrove and Julia Lockheart at The Conversation. Listening to someone discuss their dreams can help you enter their world and better understand their perspective, the pair write, while the act of story-telling can strengthen social bonds. Scientists have used electrical stimulation in the brain to allow blind people to “see” traces of letters and other shapes, reports Laura Sanders at Science News. Using electrodes impl...

SENS Research Foundation on COVID-19 and Aging
SENS Research Foundation here explains why COVID-19, like near all infectious disease, is far worse for the old. It isn't just a matter of the decline of immune function, though that is the bulk of it. Older people have a greater burden of damage and dysfunction that makes them less resilient in many other ways. Rising mortality due to infectious disease with age is the result of both (a) a greater likelihood of severe infection due to immune aging, and (b) that the individual is less likely to survive a severe infection due to general frailty. Tens of thousands die every year in the US from seasonal influenza; that is lar...

Can We Discuss Flatten-the-Curve in COVID19? My Eight Assertions
Conclusion: I did not have a clear answer for my couple. But after thinking and writing about this question it seems that the most reasonable approach in this crisis is transparent information–no matter how stark. And, crucially, we must have space for public debate. I hate this virus. I wish it never came. But we can make it worse by avoiding hard discussions on tradeoffs, the limits of modern medicine and risk. JMM P.S. I am very interested in your rebuttals to any of my assertions but will block vitriol and politicized nonsense. Related posts: The Debacle of Hydroxychloroquine and Azithromycin for ...

Fight Aging! Newsletter, May 4th 2020
The objective is to start treating chronic diseases from the root and not the symptoms of the disease. As we are starting to enroll patients in "senolytics-clinical trials," it will be imperative to assess if senolysis efficiently targets the primary cause of disease or if it works best in combination with other drugs. Additional basic science research is required to address the fundamental role of senescent cells, especially in the established contexts of disease.

COVID-19: Physicians in Shackles
By ANISH KOKA, MD A number of politically tinged narratives have divided physicians during the pandemic. It would be unfortunate if politics obscured the major problem brought into stark relief by the pandemic: a system that marginalizes physicians and strips them of agency. In practices big and small, hospital-employed or private practice, nursing homes or hospitals, there are serious issues raising their heads for doctors and their patients. No masks for you When I walked into my office Thursday, March 12th, I assembled the office staff for the first time to talk about COVID.  The prior weekend had been awa...

COVID-19 in the Context of Aging
It is widely appreciated that old people have a poor time of it when it comes to infectious disease. Seasonal influenza kills tens of thousands of older people every year in the US alone. The aged immune system functions poorly, and vaccinations for many conditions have low success rates in older people. Thus the vast majority of COVID-19 deaths are old people exhibiting immunosenescence. Given that the world at large seems to be entirely accepting of the yearly toll of influenza, while COVID-19 is classed as an apocalypse of some sort, one has to wonder how much of the hysteria surrounding COVID-19 stems from the rare - b...

No spleen? What you need to know to stay healthy
Due to injury or necessary surgery (splenectomy), some people are lacking a spleen, the organ that filters the bloodstream and helps the body fight infection. You do not need your spleen to live a normal, healthy life. However, since the spleen performs some important tasks, people who do not have one are urged to take certain precautions. What is a spleen? The spleen is a fist-sized organ that sits under your rib cage on the left side of your abdomen. Unlike the stomach, liver, or kidneys, it is not directly connected to the other organs in your abdomen. Instead, the spleen is connected to your blood vessels, with an arte...

Is Trump Acting Presidential?
Thomas A. FireyAmong the criticisms President Trump has received over his handling of COVID-19, one is that he ’s playing politics with disaster aid. TheDenver Post recently charged that he “is treating life‐​saving medical equipment as emoluments he can dole out as favors to loyalists.” Michigan Gov.Gretchen Whitmer has claimed that “vendors are being told not to send stuff here to Michigan.” Trump himself has said the governors “have to treat us well also” in order to get what they need.So far, evidence of actual favoritism is mixed. A Washington Post review of federal distribution of ventilators, ...

Research Provides No Basis for Pandemic Travel Bans
CONCLUSIONThe pre ‐​COVID‐​19 research is unanimous that governments cannot expect to rely on travel restrictions to prevent the spread of pandemics similar to influenza. Travel restrictions do not prevent the spread of disease and may only delay it for a few days or weeks if implemented prior to the interna tional transmission of the disease. The Trump administration’s travel restrictions waited until after the virus had already entered the United States, and they exempted many travelers from China, not to mention the rest of the world.[30]The research shows that the Trump administration should have known that ...

The (Sober) State of Artificial Intelligence in the Fight Against COVID-19
If you ask us at The Medical Futurist about the importance of artificial intelligence in healthcare, we will have a lot to talk about. We’ve seen how it could solve alarm fatigue in hospitals. We’ve analyzed the unusual associations the technology discovered in medicine. We believe it will usher the real era of the Art of Medicine. Dr. Meskó even embarked on a journey to better understand the language of A.I. So of course, with the COVID-19 pandemic, we had to explore the contribution of A.I. in this public health crisis. We came across promising endeavours involving such algorithms from mining for insights through...
