Particulate Air Pollution Correlates with Atherosclerosis Risk

It is known that exposure to airborne particles, such as smoke from cooking fires, correlates with increased mortality due to cardiovascular disease. Setting aside commentary on wealth and its correlation with exposure to particulate air pollution, the obvious candidate mechanism is an increase in chronic inflammation due to the effects of inhaled particles on lung tissue. Raised inflammation then leads to an accelerated progression of atherosclerosis, the fatty deposits that narrow and weaken blood vessels, ultimately leading to heart failure, stroke, and heart attack. Researchers here provide epidemiological data to support this chronic inflammation hypothesis for the harms caused by particulate air pollution. Cardiovascular diseases are the leading cause of mortality and morbidity worldwide, including in many low- and middle-income countries (LMICs). India has experienced a rapid epidemiological transition, resulting in notable prevalence of hypertension, diabetes, and obesity. India is also affected by high levels of ambient and household air pollution (HAP), resulting in a setting with high baseline cardiovascular risk and widespread exposure to high levels of air pollution. Long-term exposure to ambient particulate matter (PM) has been associated with risk of acute myocardial infarction, stroke, and cardiovascular mortality. The most plausible pathway by which PM causes cardiovascular diseases is by promoting inflammation and atherosclerosis. Atheroscler...

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...

In conclusion, high-dose NR induces the onset of WAT dysfunction, which may in part explain the deterioration of metabolic health. Towards a Rigorous Definition of Cellular Senescence https://www.fightaging.org/archives/2019/11/towards-a-rigorous-definition-of-cellular-senescence/ The accumulation of lingering senescent cells is a significant cause of aging, disrupting tissue function and generating chronic inflammation throughout the body. Even while the first senolytic drugs capable of selectively destroying these cells already exist, and while a number of biotech companies are working on the productio...

We examined human lung tissue from COPD patients and normal control subjects, and found a substantial increase in p16-expressing alveolar cells in COPD patients. Using a transgenic mouse deficient for p16, we demonstrated that lungs of mice lacking p16 were structurally and functionally resistant to CS-induced emphysema due to activation of IGF1/Akt regenerative and protective signaling.

We describe the prevalence, hazard ratios (HRs), and population-attributable fractions (PAFs) for cardiovascular disease and mortality associated with a cluster of behavioural factors (ie, tobacco use, alcohol, diet, physical activity, and sodium intake), metabolic factors (ie, lipids, blood pressure, diabetes, obesity), socioeconomic and psychosocial factors (ie, education, symptoms of depression), grip strength, and household and ambient pollution. Associations between risk factors and the outcomes were established using multivariable Cox frailty models and using PAFs for the entire cohort, and also by countries grouped ...

Authors: Abdaly MS, Azizi MS, Wijaya IP, Nugroho P, Purnamasari D Abstract Cardiovascular disease (CVD) remain a leading cause of death globally. The concept of acute myocardial infarction in young adults was uncommon. Atherosclerosis is the leading cause of CVD, including myocardial infarction, stroke, heart failure and peripheral artery disease. This condition is initiated early in childhood and progressive in nature. CVD risk factors includes hypertension, dyslipidemia and obesity play a role in the development of atherosclerosis and  components in insulin resistance syndrome.One of many risk factors for in...

Objectives: Results of the SPRINT study have influenced recent guidelines on arterial hypertension, in the identification of target SBP, but scarce attention has been paid to the consequences on DBP. However, there is evidence that reducing DBP too much can be harmful. Methods: We analyzed outcome in 4005 treated hypertensive patients (22% obesity, 8% diabetes and 21% current smoking habit) with target attended office SBP less than 140 mmHg, in relation to quintiles of DBP, cardiovascular risk profile and target organ damage (LV hypertrophy, carotid plaque and left atrial dilatation). Composite fatal and nonfatal ca...

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...
