Pain and Circumstance
My wife Diane and I visited our friend Mary in the hospital on Friday. Mary had just had her “knee replaced” — which is a rather spectacular modern procedure, unimagined not too many years ago. Another modern, commonplace aspect of this kind of surgery was being “enjoyed” by Mary – her morphine-on-demand dispenser! Her machine delivered a small dose of morphine intravenously every time she thought she needed it, with the proviso that no request would be granted until 6 minutes had passed since the last slug. Mary’s setup, combined with Memorial Day, reminded me of a landmark stud...

3 Patient Lessons: What Cancer Patients Teach Me
By YASMIN ASVAT An estimated 1.8 million people in this country may face a cancer diagnosis this year, in what has already been a bleak year of isolation and loss.   While news of the COVID-19 vaccine rolling out across the U.S. offers hope in a year of 311,000 deaths,  11 million  people face the financial pressure of unemployment, and, approximately 43 percent of the nation reports some symptoms of anxiety or depression.   It is understandable that a cancer diagnosis now may be too much to bear. And yet, somehow, many patients cope with t...

The Great Transformation
This is the title of a  book published in 1944 by the Hungarian-American political economist Karl Polanyi. It is widely considered to be an important work in political economy, so read it if you can.But the Wikipedia summary actually isn ' t bad. Polanyi addresses many of the problems and issues that concerned Karl Marx, but with 100 years of added perspective, including of course the experience of actually existing Communism. I ' m going to run a trick play here and quote from the Communist Manifesto, which was first published in 1848. (The wordsmithing was actually mostly by Friedrich Engels, who was a better commun...

Why are mRNA vaccines so exciting?
The very first vaccines for COVID-19 to complete Phase 3 testing are an entirely new type: mRNA vaccines. Vaccines of this type have never before been approved for use in any disease. How do they differ from traditional vaccines, and what makes them so exciting? How traditional vaccines work The main goal of a vaccine for a particular infectious agent, such as the virus that causes COVID-19, is to teach the immune system what that virus looks like. Once educated, the immune system will vigorously attack the actual virus, if it ever enters the body. Viruses contain a core of genes made of DNA or RNA wrapped in a coat of pro...

Top 10 Online Medical Resources For The Patients Of The Future
There are over 1 billion health-related searches on Google every single day, according to a report. This was about 7% of all searches on the platform before, and no one will be surprised when the 2020 data massively surpasses this number. After all, the internet is likely the first source to turn to with your health-related questions. But which hits are relevant, and which lead to straightforward la la land – even with the best intentions and the best A.I. toolset, the search giant can’t exclude the latter from among the results. And yet, doing so is especially important in the case of medicine and healthcare, s...

The hidden long-term cognitive effects of COVID-19
This study also found that a number of patients with COVID suffered strokes. In fact, COVID infection is a risk factor for strokes. A group of Canadian doctors found that individuals over 70 years of age were at particularly high risk for stroke related to COVID infection, but even young individuals are seven times more likely to have a stroke from this coronavirus versus a typical flu virus. Autopsy data from COVID patients in Finland suggests that another major cause of brain damage is lack of oxygen. Particularly worrisome is that several of the patients who were autopsied did not show any signs of brain injury during t...

New Cato Book: Ten Global Trends Every Smart Person Should Know: And Many Others You Will Find Interesting
In conclusion, I hope that you will buy this book and share it with your family and friends. It is meant to be a conversation piece. Instead of gathering dust on a bookshelf, it is designed to lie on a living room table (like so many architecture and interior design books), for visitors to see and discuss over a martini or glass of wine. I hope that it will alleviate some depression and anxiety, spark a fact ‐​filled discussion around the dining room table, and maybe even change some minds. Strangers things have happened. Cheers!

Fight Aging! Newsletter, August 10th 2020
This study aimed to characterize the role of BDNF in age-related microglial activation. Initially, we found that degrees of microglial activation were especially evident in the substantia nigra (SN) across different brain regions of aged mice. The levels of BDNF and TrkB in microglia decreased with age and negatively correlated with their activation statuses in mice during aging. Interestingly, aging-related microglial activation could be reversed by chronic, subcutaneous perfusion of BDNF. Peripheral lipopolysaccharide (LPS) injection-induced microglial activation could be reduced by local supplement of BDNF, while shTrkB...

4 Examples Of Merging Gaming & Digital Health
Pausing to check his map, Sam confirms that he is on the right track for his next delivery, only 2 kilometres left. He takes the opportunity to quench his thirst and check if his delivery load is securely attached to his back; some contain fragile vials of medicines and digital pills susceptible to damage if handled inappropriately. After making sure of the integrity of those packages, Sam takes a final look at his surroundings. “It’s quite peaceful with nobody around,” he thinks to himself and resumes his path.  Upon arrival at his destination, his gear is disinfected before he has access to the inte...

Quantifying Loss of Kidney Function with Age in a Human Population
Kidney function is critical to health, but, as is the case for all organs, the kidneys declines with age. The damage of aging produces harmful outcomes in many ways. For example, hypertension causes structural pressure damage in sensitive tissues in the kidneys. Further, senescent cells and other sources of chronic inflammation disrupt normal tissue maintenance processes in the kidneys, leading to the scar-like collagen deposits of fibrosis. In turn, loss of kidney function accelerates many other aspects of aging, including neurodegeneration and the onset of cognitive decline. An international study that has been ...

Your Smartphone As The Swiss Knife Of Digital Health
7:39 a.m. That’s the time that your smartphone’s sonar deems as optimal for you to wake up today. With its gentle vibration from your bedside table, you pick it up to turn off the smart alarm. As you do so, your phone asks for your permission to use the built-in sensors and camera to run your routine morning scan. It analyzes your voice; evaluates your stress level based on a facial scan; checks your vital signs; and notifies you to take a picture of that mole on your forearm in order to detect any anomalies.  Thereafter, it outputs a comprehensible report with recommendations which you can send over to your ph...

Choosing Between Life and Death During COVID-19: The A.I. Trolley Problem
Suppose you’re the sole witness of a trolley that has gone out of control, hurtling towards 5 people tied to its track, with no way to stop it in time. Good news: there’s a lever you can pull to alter its direction. Bad news: the other track isn’t safe either as it has one person tied to it. What will you do in this situation? Let the trolley continue on its initial course and kill those 5 people on the way or pull the lever to save them at the expense of that other person’s life? Source: https://www.lionsroar.com/ This ethical thought experiment, known as the Trolley Problem, was put forth by Philippa Foot b...

Neuropathologist Matija Snuderl featured in major journal discussing the use of artificial intelligence in cancer diagnostics
Dr. Matija Snuderl, neuropathologist and molecular pathologist at  New York University Langone Health, was featured ina recent article appearing inNature (March 26, 2020, Vol 579, p S14-S16). The article, which addresses the use of artificial intelligence (AI) in cancer diagnostics, opens with Dr. Snuderl experiencing a moment that many of us neuropathologists have had wherein we hesitate before signing out a case because of a feeling that something might be just a bit different about a particular specimen. That feeling prompts us to do something else (run more ancillary testing, get a consult, sleep on it and ta...
