Background: The Geroscience field focuses on the core biological mechanisms of aging, which are involved in the onset of age-related diseases, as well as declines in intrinsic capacity (IC) (body functions) leading to dependency. A better understanding on how to measure the true age of an individual or biological aging is an essential step that may lead to the definition of putative markers capable of predicting healthy aging. Objectives: The main objective of the INStitute for Prevention healthy agIng and medicine Rejuvenative (INSPIRE) Platform initiative is to build a program for Geroscience and healthy aging research going from animal models to humans and the health care system. The specific aim of the INSPIRE human translational cohort (INSPIRE-T cohort) is to gather clinical, digital and imaging data, and perform relevant and extensive biobanking to allow basic and translational research on humans. Methods: The INSPIRE-T cohort consists in a population study comprising 1000 individuals in Toulouse and surrounding areas (France) of different ages (20 years or over - no upper limit for age) and functional capacity levels (from robustness to frailty, and even dependency) with follow-up over 10 years. Diversified data are collected annually in research facilities or at home according to standardized procedures. Between two annual visits, IC domains are monitored every 4-month by using the ICOPE Monitor app developed in collaboration with WHO. Once IC decline is confirmed, participants will have a clinical assessment and blood sampling to investigate markers of aging at the time IC declines are detected. Biospecimens include blood, urine, saliva, and dental plaque that are collected from all subjects at baseline and then, annually. Nasopharyngeal swabs and cutaneous surface samples are collected in a large subgroup of subjects every two years. Feces, hair bulb and skin biopsy are collected optionally at the baseline visit and will be performed again during the longitudinal follow up. Expected Results: Recruitment started on October 2019 and is expected to last for two years. Bio-resources collected and explored in the INSPIRE-T cohort will be available for academic and industry partners aiming to identify robust (set of) markers of aging, age-related diseases and IC evolution that could be pharmacologically or non-pharmacologically targetable. The INSPIRE-T will also aim to develop an integrative approach to explore the use of innovative technologies and a new, function and person-centered health care pathway that will promote a healthy aging.

Aging is the most important risk factor for the onset of several chronic diseases and functional decline. Understanding the interplays between biological aging and the biology of diseases and functional loss as well as integrating a function-centered approach to the care pathway of older adults are crucial steps towards the elaboration of preventive strategies (both pharmacological and non-pharmacological) against the onset and severity of burdensome chronic conditions during aging. In order to tackle these two crucial challenges, ie, how both the manipulation of biological aging and the implementation of a function-centered care pathway (the Integrated Care for Older People (ICOPE) model of the World Health Organization) may contribute to the trajectories of healthy aging, a new initiative on Gerosciences was built: the INSPIRE research program. The present article describes the scientific background on which the foundations of the INSPIRE program have been constructed and provides the general lines of this initiative that involves researchers from basic and translational science, clinical gerontology, geriatrics and primary care, and public health.

Intervening in aging processes is hypothesized to extend healthy years of life and treat age-related disease, thereby providing great benefit to society. However, the ability to measure the biological aging process in individuals, which is necessary to test for efficacy of these interventions, remains largely inaccessible to the general public. Here we used NHANES physical activity accelerometer data from a wearable device and machine-learning algorithms to derive biological age predictions for individuals based on their movement patterns. We found that accelerated biological aging from our “MoveAge” predictor is associated with higher all-cause mortality. We further searched for nutritional or pharmacological compounds that associate with decelerated aging according to our model. A number of nutritional components peak in their association to decelerated aging later in life, including fiber, magnesium, and vitamin E. We additionally identified one FDA-approved drug associated with decelerated biological aging: the alpha-blocker doxazosin. We show that doxazosin extends healthspan and lifespan in C. elegans. Our work demonstrates how a biological aging score based on relative mobility can be accessible to the wider public and can potentially be used to identify and determine efficacy of geroprotective interventions.

BACKGROUND: An organism’s lifespan is inevitably accompanied by the aging process, which involves functional decline, a steady increase of a plethora of chronic diseases, and ultimately death. Thus, it has been an ongoing dream of mankind to improve healthspan and extend life.CONTENT: There are only a few proposed aging interventions: caloric restriction, exercise, and the use of low-molecular-weight compounds, including spermidine, metformin, resveratrol, and rapamycin. Resveratrol, a constituent of red wine, has long been suspected to have cardioprotective effects. Interest in this compound has been renewed in recent years, first from its identification as a chemopreventive agent for skin cancer, and subsequently from reports that it activates sirtuin deacetylases and extends the lifespans of lower organisms. Resveratrol have been shown to prevent and reduce the severity of age-related diseases such as atherosclerosis, stroke, myocardial infarct, diabetes, neurodegenerative diseases, osteoarthritis, tumors and metabolic syndrome, along with their ability to extend lifespan.SUMMARY: The purpose of aging research is the identification of interventions that may avoid or ameliorate the ravages of time. In other words, the quest is for healthy aging, where improved longevity is coupled to a corresponding healthspan extension. It is only by extending the healthy human lifespan that we will truly meet the premise of the Roman poet Cicero: “No one is so old as to think that he may not live a year.”KEYWORDS: aging, caloric restriction, mimetic, healthspan, sirtuin activator

Cognitive processing of social and nonsocial information changes with age. These processes range from the ones that serve “mere” cognitive functions, such as recall strategies and reasoning, to those that serve functions that pertain to self-regulation and relating to others. However, aging and the development of social cognition unfold in different cultural contexts, which may assume distinct social norms and values. Thus, the resulting age-related differences in cognitive and social cognitive processes may differ across cultures. On the one hand, biological aging could render age-related differences in social cognition universal; on the other hand, culture may play a role in shaping some age-related differences. Indeed, many aspects of cognition and social cognition showed different age and culture interactions, and this makes the study of these phenomena more complex. Future aging research on social cognition should take cultural influences into consideration.

: Patterns of DNA methylation, the best characterized epigenetic modification, are modulated by aging. In humans, different studies at both site-specific and genome-wide levels have reported that modifications of DNA methylation are associated with the chronological aging process but also with the quality of aging (or biological aging), providing new perspectives for establishing powerful biomarkers of aging. : In this article, the role of DNA methylation in aging and longevity has been reviewed by analysing literature data about DNA methylation variations occurring during the lifetime in response to environmental factors and genetic background, and their association with the aging process and, in particular, with the quality of aging. Special attention has been devoted to the relationship between nuclear DNA methylation patterns, mitochondrial DNA epigenetic modifications, and longevity. Mitochondrial DNA has recently been reported to modulate global DNA methylation levels of the nuclear genome during the lifetime, and, in spite of the previous belief, it has been found to be the target of methylation modifications. : Analysis of DNA methylation profiles across lifetime shows that a remodeling of the methylome occurs with age and/or with age-related decline. Thus, it can be an excellent biomarker of aging and of the individual decline and frailty status. The knowledge about the mechanisms underlying these modifications is crucial since it might allow the opportunity for targeted treatment to modulate the rate of aging and longevity.

The number of older adults in our society is increasing rapidly. Aging is complex and may occur at varying rates across multiple domains, including biological aging, cognitive aging, and emotional aging. Age-related medical conditions are now among the leading causes of morbidity and mortality among older adults, making healthy aging a major public health priority. Successful aging encompasses more than longevity, medical health, or freedom from disability. It can be viewed as a multidimensional construct including minimization of disability and medical illness combined with maximization of physical, cognitive, emotional, and social functioning. We review the current literature regarding successful aging. We also discuss strategies to improve the likelihood of successful aging and several key advances, such as definitions of successful aging in different populations, neuroplasticity of aging, wisdom as an empirical construct, the concept of a good (or successful) death, and the development of age-friendly communities.  This review contains 3 figures, 5 tables, and 53 references. Key words: aging, elderly, older adult, successful aging, successful aging interventions

Purpose: To describe the natural history of acquired vitelliform lesions (AVLs) associated with different types of pigment epithelial detachments (PEDs) in dry age-related macular degeneration. Methods: A retrospective review of clinical examination and multimodal imaging data of patients with AVLs associated with PED(s) was performed. Results: This study included 25 eyes of 17 patients. The mean age of patients was 67.2 ± 9.7 (47–83) years. The mean follow-up time was 32.6 ± 16.2 (12–66) months, excluding four patients (five eyes) that were lost to follow-up. The mean logMAR BCVA was 0.21 ± 0.16 at baseline and 0.38 ± 0.28 at final visit ( p = 0.016). At the end of the follow-up period, PEDs enlarged in eight eyes (40%) and were unchanged in two eyes (10%). Spontaneous resolution of the central PED(s) with AVLs was seen in four (20%) eyes. Rupture of the PED(s) occurred in four eyes (20%), with two developing central foveolar atrophy afterwards. Overall, central foveolar atrophy was seen ultimately in four eyes (20%). Conclusion: It seems that high PED size may be a risk factor for PED rupture during follow-up. 1/3 of the eyes ended up with unfavorable anatomical outcome.

Background. Loneliness and social isolation are emerging public health challenges for aging populations. Methods. We followed N=11,305 US Health and Retirement Study (HRS) participants aged 50-95 from 2006-2014 to measure persistence of exposure to loneliness and social isolation. We tested associations of longitudinal loneliness and social-isolation phenotypes with disability, morbidity, mortality, and biological aging through 2018. Results. During follow-up, 18% of older adults met criteria for loneliness and, for 6%, symptoms persisted across two or more follow-up assessments. For social isolation, these fractions were 21% and 8%. HRS participants who experienced loneliness and social isolation were at increased risk for disease, disability, and mortality. Older adults experiencing persistent loneliness were at a 59% increased hazard of mortality compared to those who were never lonely. For social isolation, the increase was 28%. Effect-sizes were somewhat larger for counts of prevalent activity limitations and somewhat smaller for counts of prevalent chronic diseases. Covariate adjustment for socioeconomic and psychological risks attenuated but did not fully explain associations. Older adults who experienced loneliness and social isolation also exhibited physiological indications of advanced biological aging (Cohen's-d for persistent loneliness and social isolation=0.26 and 0.21, respectively). For loneliness, but not social isolation, persistence of symptoms was associated with increased risk. Conclusion. Deficits in social connectedness prevalent in a national sample of older adults in the US were associated with morbidity, disability, and mortality and with more advanced biological aging. Bolstering social connection to interrupt experiences of loneliness may promote healthy aging.

Antiaging therapies show promise in model organism research. Translation to humans is needed to address the challenges of an aging global population. Interventions to slow human aging will need to be applied to still-young individuals. However, most human aging research examines older adults, many with chronic disease. As a result, little is known about aging in young humans. We studied aging in 954 young humans, the Dunedin Study birth cohort, tracking multiple biomarkers across three time points spanning their third and fourth decades of life. We developed and validated two methods by which aging can be measured in young adults, one cross-sectional and one longitudinal. Our longitudinal measure allows quantification of the pace of coordinated physiological deterioration across multiple organ systems (e.g., pulmonary, periodontal, cardiovascular, renal, hepatic, and immune function). We applied these methods to assess biological aging in young humans who had not yet developed age-related diseases. Young individuals of the same chronological age varied in their “biological aging” (declining integrity of multiple organ systems). Already, before midlife, individuals who were aging more rapidly were less physically able, showed cognitive decline and brain aging, self-reported worse health, and looked older. Measured biological aging in young adults can be used to identify causes of aging and evaluate rejuvenation therapies.

Abstract Why people of the same age show differences in age-related functional decline, and whether biological aging can be slowed down through lifestyle changes and therapeutics is a subject of active research. Molecular tools that predict biological age based on DNA methylation markers, known as epigenetic clocks, are facilitating these efforts. In this issue, Kresovich et al. (Am J Epidemiol. 2020;XXX(XX):XXXX–XXXX) investigated a cohort of non-Hispanic white women, demonstrating positive relations between adiposity measures and the ticking rate of epigenetic clocks in blood. This commentary emphasizes that integrating molecular and genetic epidemiology approaches is crucial to dissect the complex relationship between obesity and epigenetic aging. The early life period is explored as a unique opportunity to gain novel insights into links between developmental processes and aging in later life. Lastly, the landscape of the next frontier in aging research is described in light of the imperative for transdisciplinary approaches to outline a shared vision and public health implementation dilemmas.
