This study shows that CA are released from periventricular and subpial regions to the cerebrospinal fluid and are present in the cervical lymph nodes, into which cerebrospinal fluid drains through the meningeal lymphatic system. We also show that CA can be phagocytosed by macrophages. We conclude that CA can act as containers that remove waste products from the brain and may be involved in a mechanism that cleans the brain. Moreover, we postulate that CA may contribute in some autoimmune brain diseases, exporting brain substances that interact with the immune system, and hypothesize that CA may contain brain markers that m...

A Large Study of Aspirin Use Finds Reduced Mortality, Contradicting the Recent ASPREE Study Results
The back and forth over whether regular aspirin use is beneficial continues with the publication of results from analysis of a large patient population that show a 15% reduction in all cause mortality in patients using aspirin. This contradicts the much smaller (but still large in and of itself) ASPREE clinical trial, in which patients using aspirin exhibited a small increase in mortality in comparison to their peers. As in that earlier study, the data here strongly suggests that benefits and risks vary with patient characteristics, such as whether or not a patient is overweight. Aspirin is thought to be a weak calo...

Seizing the Opportunity in America ’ s Opioid Crisis
“Perhaps everything that is terrible is, in the deepest sense, something that wants our love.” – Rilke The overdose epidemic in the U.S. has been called “the greatest public health crisis of our time.” It’s also our greatest opportunity. The opioid crisis is an identity crisis: it’s a challenge to how we see ourselves. Do we truly believe that we are all in this together? One answer leads us deeper into despair. The other, into a hopeful future. It’s been said that “doing more things faster is no substitute for doing the right things.” What are the “right things,” the measures that can r...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

In conclusion, in the absence of obesity, visceral adipose tissue possesses a pronounced anti-inflammatory phenotype during aging which is further enhanced by exercise. Methods of Inducing Cellular Damage are Rarely Relevant to Aging, and the Details Matter https://www.fightaging.org/archives/2019/08/methods-of-inducing-cellular-damage-are-rarely-relevant-to-aging-and-the-details-matter/ One of the major challenges in aging research is determining whether or not models of cellular or organismal damage and its consequences are in any way relevant to the natural processes of aging. One can hit a brick with...

Landmark Results Achieved in Aging and Chronic Disease: Danish Group Extends Disease-free Life by 8 Years
By WILLIAM H. BESTERMANN JR., MD New Scientific Breakthroughs Can Provide a Longer Healthier Life Twenty-one years of follow-up comparing usual care with a protocol-driven team-based intervention in diabetes proved that healthy life in humans can be prolonged by 8 years. These results were achieved at a lower per patient per year cost. Aging researchers have been confident that we will soon be able to prolong healthy life. This landmark study shows this ambitious goal can be achieved now with lifestyle intervention and a few highly effective proven medications. These medications interfere with the core molecular biol...

Colorectal cancer screening before age 50?
Colorectal cancer (CRC) is the second leading cause of cancer death in the United States. There is strong evidence that screening for CRC with colonoscopy, other visual exams, or stool-based tests can reduce CRC mortality. As a result, several expert organizations have long recommended regular CRC screening for US adults ages 50 to 75. In 2018, the American Cancer Society (ACS) became the first major organization to recommend CRC screening starting at 45. Why did the ACS recommend CRC screening starting at 45? The incidence of CRC and mortality from the disease has declined over the last several decades among adults over 5...

In this study, we found that senescent chondrocytes isolated from OA patients secrete more EVs compared with nonsenescent chondrocytes. These EVs inhibit cartilage ECM deposition by healthy chondrocytes and can induce a senescent state in nearby cells. We profiled the miR and protein content of EVs isolated from the synovial fluid of OA joints from mice with SnCs. After treatment with a molecule to remove SnCs, termed a senolytic, the composition of EV-associated miR and protein was markedly altered. The senolytic reduced OA development and enhanced chondrogenesis, and these were attributable to several specific differenti...

This study defines a new clinically relevant concept of T-cell senescence-mediated inflammatory responses in the pathophysiology of abnormal glucose homeostasis. We also found that T-cell senescence is associated with systemic inflammation and alters hepatic glucose homeostasis. The rational modulation of T-cell senescence would be a promising avenue for the treatment or prevention of diabetes.

Aspirin for primary prevention of cardiovascular disease, part 2
Update In March 2019, the American College of Cardiology (ACC) and the American Heart Association (AHA) released new guidelines that suggest that most adults without a history of heart disease should not take low-dose daily aspirin to prevent a first heart attack or stroke. Based on the ASPREE, ARRIVE, and ASCEND trials, the ACC/AHA guidelines concluded that the risk of side effects from aspirin, particularly bleeding, outweighed the potential benefit. The new guidelines do not pertain to people with established cardiovascular disease, in whom the benefits of daily aspirin have been found to outweigh the risks. ___________...

Growing Enthusiasm for the Development of Geroprotectors
A geroprotector is a drug or supplement that either slows the underlying causes of aging or produces a greater resistance to the damage of aging. In either case health is prolonged and mortality decreased. Calorie restriction mimetics are the best example of the type, but the category is expansive enough to include well known drugs such as aspirin. As you might imagine of a class of treatments that includes aspirin, the size of effect when it comes to additional years of life is fairly small, even in those cases in which the benefits are reliable. Geroprotectors largely work through upregulation of stress responses, someth...
