ثمة اختلاف في الطريقة التي يشيُّخ فيها نظام الأوعية الدموية ومعدَّل تقدُّم مرض تصلُّب الشرايين (زيادة سُمك جدران الشريان أو تكوُّن الانسداد الشرياني) بين الرجال والنساء مع مرور الوقت وتؤثر هذه الاختلافات المرتبطة بالنوع والعمر بشكل مباشر على عوامل إصابة النساء بالأمراض القلبية الوعائية.
Scientists at Sanford Burnham Prebys Medical Discovery Institute and Harvard University have discovered that mitochondria trigger senescence, the sleep-like state of aged cells, through communication with the cell’s nucleus—and identified an FDA-approved drug that helped suppress the damaging effects of the condition in cells and mice. The discovery, published in Genes & Development, could lead to treatments that promote healthy aging or prevent age-associated diseases such as cancer, Alzheimer’s disease, heart disease and more.
Few studies have examined how the neighborhood’s physical environment relates to cognition in older adults. Researchers categorized 4,716 individuals by apolipoprotein E (APOE) genotype – a genetic risk factor for Alzheimer’s disease (AD) to determine if there are cognitive benefits of living in neighborhoods with greater access to social, walking and retail destinations. Results showed that the positive influence of neighborhood environments on cognition are strongest among those who are at the lowest risk for AD, specifically APOE ε2 carriers.

A forma em que o sistema vascular envelhece e o ritmo ao qual a aterosclerose, o enrijecimento das paredes arteriais ou o acúmulo de bloqueios arteriais, progride diferem entre homens e mulheres. Essas diferenças relacionadas ao sexo e à idade afetam diretamente o risco de desenvolver doença vascular nas mulheres.
Les hommes et les femmes diffèrent dans le vieillissement de leurs systèmes vasculaires et dans la vitesse de progression de l’athérosclérose, le durcissement des parois artérielles ou l'accumulation d'obstructions dans les artères. Ces différences liées au sexe et à l'âge impactent directement le risque qu'une femme développe une maladie cardiovasculaire.

UC San Diego and IBM researchers reveal a new understanding of how our microbiomes change as we age, setting the stage for future research on the role microbes play in accelerating or decelerating the aging process and influencing age-related diseases.
By the time they reach menopause — which officially begins one year after a woman’s last period — many women think they have their lives figured out. Careers are well established; children are grown and independent; and there’s more time for leisure and self-care. Yet many women in their 40s and 50s are surprised to suddenly notice changes on their skin, including acne and age spots. Fortunately, dermatologists from the American Academy of Dermatology say that while many of these changes are inevitable due to hormones, there is a lot women can do at home to lessen these effects.
Dr. Chen Hou and his research collaborators have found an answer to the decades-old question of why naked mole-rats with high oxidative damage live 10 times longer than mice of comparative weight.“The long lifespan of the East African naked mole-rats raises one of the most serious paradoxes in the study of aging,” says Hou, an associate professor of biological sciences at Missouri S&T.
UC San Diego researchers use 3D human gut organoids to reveal the molecular system that keeps intestinal linings sealed, demonstrate how the system breaks down and how it can be strengthened with the diabetes drug metformin.

Is it possible to investigate menopausal age, or not? In more than one in three women aged 50, the body provides no clear answer about the menopause, a University of Gothenburg study shows. Increased use of hormonal intrauterine devices and contraceptive pills are the cause.
Health insurance costs weigh heavily on the minds of many middle-aged adults, and many are worried for what they’ll face in retirement or if federal health policies change, according to a new study. More than a quarter of people in their 50s and early 60s lack confidence that they’ll be able to afford health insurance in the next year, and the number goes up to nearly half when they look ahead to retirement.

People who eat or drink more foods with the antioxidant flavonol, which is found in nearly all fruits and vegetables as well as tea, may be less likely to develop Alzheimer’s dementia years later, according to a study published in the January 29, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Researchers at Albany Medical College in New York have discovered that a specific type of immune cell accumulates in older brains, and that activating these cells improves the memory of aged mice. The study, which will be published February 5 in the Journal of Experimental Medicine (JEM), suggests that targeting these cells might reduce age-related cognitive decline and combat aging-associated neurodegenerative disease in humans.
Dr. Kyong Hee Chee’s research interests include aging and the life course and community development.
Evaluating the effectiveness of therapies for neurodegenerative diseases is often difficult because each patient’s progression is different. A new study shows artificial intelligence (AI) analysis of blood samples can predict and explain disease progression, which could one day help doctors choose more appropriate and effective treatments for patients.
Researchers at Beth Israel Deaconess Medical Center (BIDMC) have found that orthostatic hypotension was not associated with higher risk of cardiovascular events, falls, or fainting among participants in The Systolic Blood Pressure Intervention Trial. In a study published in the journal Hypertension, the scientists showed that hypertension treatment had no impact on the link between OH and cardiovascular outcomes or other adverse events.

Many Medicare patients with new episodes of low back pain receive care inconsistent with current guidelines – including high use of opioids and advanced imaging tests, reports a study in the February issue of Medical Care. The journal is published in the Lippincott portfolio by Wolters Kluwer.
Wide swings in blood pressure readings among young adults are associated with a higher risk of cardiovascular disease by middle age, a new analysis led by Duke Health researchers shows. The finding, publishing Jan. 22 in JAMA Cardiology, suggests that the current practice of averaging blood pressure readings to determine whether medications are necessary could be masking a potential early warning sign from the fluctuations themselves.
