On the bias of science: a digression
This series has elicited a couple of what I consider idiotic and unpublishable comments to the effect that I have just proved why people don ' t trust science. This is a basic problem in science communication to the general public that is much discussed. Here ' s my two cents.The problem is that scientists are generally reluctant to make highly definitive statements. Science is a continuously progressive endeavor and it ' s not uncommon for what we thought we knew yesterday to turn out to be not quite right today. Many conclusions are probabilistic - we ' re 90% or 95% sure of something. Sometimes an association holds unde...

Alcohol, Smoking, Drugs: How Technology Can Help
The global statistics on substance use are disquieting. Globally, about 3 million people die every year from alcohol abuse. Tobacco kills up to half of its users – over 8 million people annually. And the UN’s 2021 World Drug Report estimated that around 275 million people used drugs worldwide in 2020, while over 36 million people suffered from drug use disorders.
Disruptive technologies could act only as additional tools for managing preventive or reactive treatment for both victims and physicians next to therapy. Alcohol content-measuring wristbands, smart lighters, nicotine tracking wearables, stop smoking apps, virt...

In conclusion, our study demonstrated that elevated cumulative SBP or DBP was independently associated with increased risk of CVD in the Chinese population. Among participants with 15-year cumulative BP levels higher than the median, that is, 1970.8/1239.9 mmHg-year for cumulative SBP/DBP, which was equivalent to maintaining SBP/DBP level higher than 131/83 mmHg in 15 years, the CVD risk would increase significantly irrespective of whether or not the BP measurements at one examination was high. Our findings emphasize the importance of cumulative BP level in identifying individuals with high risk of CVD in the future.

Heart Failure Correlates with Increased Cancer Risk
https://www.fightaging.org/archives/2021/07/heart-failure-correlates-with-increased-cancer-risk/
Age-related disease results from the underlying cell and tissue damage that causes aging. Different people accumulate that damage at modestly different rates, the result of lifestyle choices and exposure to infectious disease. Thus the presence of a sufficient burden of damage to produce one age-related disease will be accompanied by a ...

The explosion of mental health apps raises substantial opportunities –and tough questions
In the eyes of the tech industry, mental health treatment is an area ripe for disruption.
In any given year, 1 in 5 adults in the U.S. experience a form of mental illness, according to federal estimates. And research indicates only about half of them receive treatment in a system that is understaffed and ill distributed to meet demand.
For tech startups looking to cash in on unmet need, that translates into more than 50 million potential customers.
Venture capital firms invested more than $2.4 billion in digital behavioral health apps in 2020 — more than twice the amount invested in 2019 — touting support or treatment ...

In conclusion, in our prospective community-based study, aging-related biomarkers were associated with measures of subclinical atherosclerosis cross-sectionally and with all-cause mortality prospectively, supporting the concept that these biomarkers may reflect the aging process in community-dwelling adults.

In conclusion, a number of high-income countries, changes in health expectancies over time have not kept pace with the growth in life expectancy. That is, people are living longer but disability and poor health are occupying an increasing proportion of later life. Our findings suggest that countries still need to make significant progress to achieve the WHO's Decade of Healthy Ageing goal of healthier, longer lives for all.

Progress on Understanding Why Human Growth Hormone Receptor Variants are Associated with Greater Longevity
A few years back, researchers noted that a common growth hormone receptor gene variant was associated with greater life expectancy in humans. There was some theorizing as to possible mechanisms at the time, following the usual paths for anything that touches on growth hormone or its receptor. In short-lived mammals such as mice, loss of function in growth hormone or its receptor produces small body size and increased healthy longevity. The present record for mouse longevity is held by a growth hormone receptor knockout lineage. In humans, members of the small Laron syndrome population exhibit an analogous disruption of gro...

The Mainstream Media is Slowly Becoming Less Skeptical of Work to Extend the Healthy Human Life Span
One can't maintain dismissive skepticism forever in the face of scientific and medical development communities that are ever more engaged in the development of therapies to address the mechanisms of aging. To pick one example, senolytic treatments that clear senescent cells from aged tissues are producing consistently amazing data in mice: rejuvenation, extension of healthy life, reversal of measures of many specific age-related diseases. We'll soon know how well the more viable senolytics perform in human trials, as the preliminary data from the use of dasatinib and quercetin shows that it does selectively destroy senesce...

Considering Exercise as a Means to Slow the Progression of Aging
It is well known that regular exercise can slow the progression of many age-related declines, and reduce mortality risk in late life. Different forms of exercise, such aerobic exercise versus strength training, appear to produce different, overlapping benefits. This is concretely demonstrated in animal models, while the human epidemiological data, which can only show correlations, is supportive of the thesis that exercise produces changes in metabolism that modestly slow the onset of age-related declines.
Exercise is a lifestyle intervention with known antiaging effects capable of counteracting several of the hall...

Cell Signaling via Exosomes in the Development of Vascular Calcification
https://www.fightaging.org/archives/2021/05/cell-signaling-via-exosomes-in-the-development-of-vascular-calcification/
Vascular calcification is a feature of aging, a process in which cells in the blood vessel wall take on inappropriate identities and activities that are more appropriate to bone tissue. Evidence of recent years implicates chronic inflammation and the presence of senescent cells in this process. Senescent cells caus...

Epistemology VI: Epidemiology
Epidemiology originally largely meant studying how infectious diseases spread, and that ' s still a major concern of epidemiologists. However, it also includes the study of any and every environmental or behavioral factor affecting human health. For example, the finding that smoking tobacco causes lung cancer (not to mention a bazillion other diseases) is an epidemiological finding. Epidemiology is largely an observational science, given the ethical prohibition against exposing humans to potentially hazardous conditions for experimental purposes. That ' s not to say it hasn ' t been done, with the victims being ...

This study is consistent with previous evidence showing that inflammaging, or age-related inflammation, is naturally heightened in the nervous system. Moreover, the authors disproved their hypothesis that anti-inflammatory microglia-specific genes are responsible for the elevated inflammatory response in aged brains since the expression of anti-inflammatory mediators was elevated in middle-aged brains following infection. Thus, the cause for the increase in pro-inflammatory genes remains to be elucidated.
