Sleep well — and reduce your risk of dementia and death
This study controlled for demographic characteristics including age, marital status, race, education, health conditions, and body weight.
In the second study, researchers in Europe (including France, the United Kingdom, the Netherlands, and Finland) examined data from almost 8,000 participants from a different study and found that consistently sleeping six hours or less at age 50, 60, and 70 was associated with a 30% increase in dementia risk compared to a normal sleep duration of seven hours. The mean age of dementia diagnosis was 77 years. This study controlled for sociodemographic, behavioral, cardiometabolic, and menta...

Ultrasonic Biopsy Needle for Larger Tissue Samples
Researchers at Aalto University in Finland have developed an ultrasonically actuated needle that can retrieve a large amount of tissue during a biopsy, without the pain and complications associated with using bigger needles. The technique could be very useful when clinicians need to obtain tissue samples for molecular tumor diagnostics, since obtaining high quality samples is crucial, given the expense of molecular profiling procedures. The technique may also help to reduce patient inconvenience associated with repeat biopsies because of an initial poor tissue sample.
“Biopsy yields – the amount of tissue extrac...

Study: Depression affects visual perception … making it more accurate
The brightness of Figures A and B is exactly the same, but they are perceived differently due to a difference in the background. This illusion was perceived similarly by the patients and healthy control subjects. The contrast of Figures C and D is exactly the same as well, but the perception of this illusion was weaker among the depressed patients than the control subjects. (Salmela et al, J. Psychiatry Neurosci, 2021)

Corporate Taxes: Rates Down, Revenues Up
Chris EdwardsU.S. Treasury Secretary Janet Yellen recentlycomplained about a“30-year race to the bottom on corporate tax rates,” and is pushing for a higher U.S. rate and a global minimum rate. Yellenwants to make sure that corporate taxes “raise sufficient revenue to invest in essential public goods and respond to crises.” EconomistGabriel Zucmanapproved of the proposed tax hike, saying corporations should “pay more in taxes, instead of them paying less and less. "Zucman ’s claim about “less and less” is incorrect when looking across the major economies in recent decades. TheNew York Times charts the OECD ...

Nuclear Power Costs
Peter Van DorenTheNew Yorkerrecently published a shortarticle about environmentalists who support nuclear power because they believe it is an essential component of any strategy to reduce greenhouse gas emissions. The article discussed the risks from nuclear accidents, such as Fukushima and correctly noted that more than a thousand people died in the forced evacuation of the area, dwarfing the expected direct health effects of radiation exposure.A recentpaper extended that analysis by examining the effects of the shut ‐down of all nuclear power plants in Japan following the Fukushima accident in March 2011. ...

Driverless Cars or Keyboardless EMRs? Which Do We Need Most?
By HANS DUVEFELT
I love cars and dislike computers.
My car takes me where I need to go, but it also gives me pleasure along the way. I have had it for just about ten years now and I have driven it almost 300,000 miles. It feels like an extension of me. Everything about it is just perfect for the way I drive and the things I need to do with it. From the sumptuously cavernous interior to the rugged all wheel drive features and the studded Finnish snow tires, it takes me pretty much anywhere, anytime. Why anyone would want to travel in a car without the sublime pleasure of driving it is beyond my comprehension.

Fight Aging! Newsletter, December 28th 2020
In conclusion, our study demonstrated that the molecular processes of aging are relatively subtle in their progress, and the aging process of every tissue depends on the tissue's specialized function and environment. Hence, individual gene or process alone cannot be described as the key of aging in the whole organism.
Mouse Age Matters: How Age Affects the Murine Plasma Metabolome
A large part of metabolomics research relies on experiments involving mouse models, which are usually 6 to 20 weeks of age. However, in this age range mice undergo dramatic developmental changes. Even small age differences may l...

Why male circumcision should be delayed
In Finland, lawmakers recently voted to make an existing ban on female genital mutilation more explicit by outlining punishments for such manipulation under the Finnish criminal law. This bill’s passage was widely applauded as it furthers the global efforts to eradicate female genital mutilation (FGM). While the bill received majority support in the parliament, a […]Find jobs at Careers by KevinMD.com. Search thousands of physician, PA, NP, and CRNA jobs now. Learn more.

Better Cardiovascular Fitness in Mid-Life Correlates with Lower Risk of Later Dementia
In this study, we observed that having the ideal CVH metrics, and ideal behavioral CVH metrics in particular, from midlife onwards is associated with a reduced risk of dementia as compared with people having poor CVH metrics. Maintaining life-long health behaviors may be crucial to reduce late-life risk of dementia.

Smart Ring Monitors Body Temperature, May Spot COVID Fever Early
In this study involving 50 volunteers who owned Oura rings, the onset of fever was easily identified in the data collected by the rings. “The chart tracking people who had a fever looked like it was on fire,” said Smarr. Interestingly, the researchers observed that the onset of fever occurred before people began noticing COVID symptoms, suggesting that the technology could function as an early warning system. In some cases, people didn’t notice any other symptoms apart from the fever.
“It supports the hypothesis that some fever-like events may go unreported or unnoticed without being truly asymptomat...

Follow-up on my Eight COVID Assertions
Yesterday’s post generated some good comments.
Two emergency medicine specialists felt that I was both wrong and insulting in saying that hospitals were not overwhelmed.
As a doc in NYC, I would suggest that your assertion 3 was indeed quite wrong and will be wrong in many more places before we are done— Josh Socolow (@Docjoshsoc) December 13, 2020

Several Alzheimer's Associated Gene Variants Appear to Affect the Efficiency of Microglia
Microglia are innate immune cells of the brain, similar to macrophages in the rest of the body, but with a larger portfolio of activities. They are not just chasing down pathogens and cleaning up molecular waste, but are also deeply involved in maintaining the function and connectivity of neurons in brain tissue. Here, researchers note that several genetic variants that are either problematic or protective when it comes to Alzheimer's disease risk and progression affect the ability of microglia to clear amyloid-β aggregates from brain tissue. While therapies targeting amyloid-β accumulation have so far failed to produce ...

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...
