Background and ObjectivesVascular theories of cognitive aging have focused on macrovascular changes and cognitive decline. However, according to the artery-size hypothesis, microvascular changes, such as those that underlie changes in erectile function, may also play an important role in contributing to cognitive decline. Thus, we examined associations between erectile function, sexual satisfaction, and cognition starting… Continue reading Erectile Function, Sexual Satisfaction, and Cognitive Decline in Men From Midlife to Older Adulthood

Higher intake of dietary flavonols, specifically dietary quercetin, is associated with lower odds of frailty onset over 12 years of follow-up among adults in the Framingham Heart Study
BackgroundPolyphenolic antioxidants derived from plant foods may reduce oxidative stress and frailty, but the effect of the polyphenol subclass of dietary flavonoids and their subclasses on frailty is uncertain.ObjectivesTo determine the association between dietary flavonoids, their subclasses, quercetin (a specific flavonol), and frailty onset in adults.MethodsThis prospective cohort study included individuals from the Framingham Heart… Continue reading Higher intake of dietary flavonols, specifically dietary quercetin, is associated with lower odds of frailty onset over 12 years of follow-up among adults in the Framingham Heart Study
Rilmenidine extends lifespan and healthspan in Caenorhabditis elegans via a nischarin I1-imidazoline receptor
Repurposing drugs capable of extending lifespan and health span has a huge untapped potential in translational geroscience. Here, we searched for known compounds that elicit a similar gene expression signature to caloric restriction and identified rilmenidine, an I1-imidazoline receptor agonist and prescription medication for the treatment of hypertension. We then show that treating Caenorhabditis elegans with rilmenidine… Continue reading Rilmenidine extends lifespan and healthspan in Caenorhabditis elegans via a nischarin I1-imidazoline receptor
Middle-age high normal serum sodium as a risk factor for accelerated biological aging, chronic diseases, and premature mortality
It is known that some people age faster than others, some people live into old age disease-free, while others develop age-related chronic diseases. With a rapidly aging population and an emerging chronic diseases epidemic, finding mechanisms and implementing preventive measures that could slow down the aging process has become a new challenge for biomedical research… Continue reading Middle-age high normal serum sodium as a risk factor for accelerated biological aging, chronic diseases, and premature mortality
Community-level age bias and older adult mortality
As the older adult population increases, understanding the health effects of bias against older adults is increasingly important. Whether structural forms of age bias predict worse health has received limited attention.ObjectiveWe hypothesized that communities with greater age bias would have higher mortality among residents aged 65 and older. We expected the association to be unique… Continue reading Community-level age bias and older adult mortality
A dietary intervention for vasomotor symptoms of menopause: a randomized, controlled trial
Objective Postmenopausal vasomotor symptoms disrupt quality of life. This study tested the effects of a dietary intervention on vasomotor symptoms and menopause-related quality of life.Methods Postmenopausal women (n = 84) reporting at least two moderate-to-severe hot flashes daily were randomly assigned, in two successive cohorts, to an intervention including a low-fat, vegan diet and cooked soybeans (½ cup [86… Continue reading A dietary intervention for vasomotor symptoms of menopause: a randomized, controlled trial
Older adults with lower working memory capacity benefit from transcranial direct current stimulation when combined with working memory training: A preliminary study
Aging is a very diverse process: successful agers retain most cognitive functioning, while others experience mild to severe cognitive decline. This decline may eventually negatively impact one’s everyday activities. Therefore, scientists must develop approaches to counteract or, at least, slow down the negative change in cognitive performance of aging individuals. Combining cognitive training and transcranial… Continue reading Older adults with lower working memory capacity benefit from transcranial direct current stimulation when combined with working memory training: A preliminary study
Psychological resilience in older adults with type 2 diabetes from the Look AHEAD Trial
BackgroundThere is growing interest in identifying factors associated with healthy aging. This cross-sectional study evaluated associations of psychological resilience with factors associated with aging in older adults with type 2 diabetes mellitus (T2DM).MethodsParticipants were 3199 adults (72.2 ± 6.2 years of age, 61% female, 61% White, body mass index [BMI] = 34.2 ± 8.2 kg/m2) with T2DM enrolled in Look AHEAD (a multi-site… Continue reading Psychological resilience in older adults with type 2 diabetes from the Look AHEAD Trial
Psychological factors substantially contribute to biological aging: evidence from the aging rate in Chinese older adults
We have developed a deep learning aging clock using blood test data from the China Health and Retirement Longitudinal Study, which has a mean absolute error of 5.68 years. We used the aging clock to demonstrate the connection between the physical and psychological aspects of aging. The clock detects accelerated aging in people with heart,… Continue reading Psychological factors substantially contribute to biological aging: evidence from the aging rate in Chinese older adults
