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
Causal analysis identifies small HDL particles and physical activity as key determinants of longevity of older adults
BackgroundThe hard endpoint of death is one of the most significant outcomes in both clinical practice and research settings. Our goal was to discover direct causes of longevity from medically accessible data.MethodsUsing a framework that combines local causal discovery algorithms with discovery of maximally predictive and compact feature sets (the “Markov boundaries” of the response)… Continue reading Causal analysis identifies small HDL particles and physical activity as key determinants of longevity of older adults
Motion, Relation, and Passion in Brain Physiological and Cognitive Aging
Abstract: The aim of the current paper was to present important factors for keeping the basic structures of a person’s brain function, i.e., the grey and white matter, intact. Several lines of evidence have shown that motion, relation, and passion are central factors for preserving the neural system in the grey and white matter during… Continue reading Motion, Relation, and Passion in Brain Physiological and Cognitive Aging
Inflammaging is driven by upregulation of innate immune receptors and systemic interferon signaling and is ameliorated by dietary restriction
Highlights•Innate immune system receptors/interferon/Stat1 axis triggers inflammaging•Both lifetime and short-time dietary restriction (DR) treatments ameliorate inflammaging•Transcriptome alteration caused by aging, lifetime, or short-term DR are tissue specific•Aging induces a general open chromatin rearrangement, which is not rescued by DRSummaryAging is characterized by a chronic low-grade inflammation known as inflammaging in multiple tissues, representing a risk… Continue reading Inflammaging is driven by upregulation of innate immune receptors and systemic interferon signaling and is ameliorated by dietary restriction
