BACKGROUND: Individual perception of memory performance (i.e., subjective memory) is assessed using a variety of approaches. This article focuses on 2 such approaches: (1) self-comparison assessments that attempt to capture changes in memory ability over a period of time and (2) age-anchored comparisons that assess how an individual perceives their memory in relation to others their age. These different types of assessment may relate to psychological well-being differently due to the underlying mechanisms of assessment...

Human beings impose subjective, time-related interpretations on their existence, and the experience of time is a major aspect of lifespan development. In this mini-review, we understand subjective time as the way individuals subjectively perceive and evaluate the passing of their personal "objective" lifetime. A broad range of constructs and operationalizations has been developed in (gero-) psychology to capture subjective time, including future time perspective, personal goals, or autobiographical memories...

BACKGROUND: It is known from clinical practice and observational studies that elderly patients with a diagnosis of inflammatory rheumatic diseases (IRD) bear a significantly increased risk for cardiovascular diseases such as coronary artery disease (CAD) and heart failure. The molecular mechanism, however, is still not known. Recently, high mobility group protein B1 (HMGB1), a ubiquitous, highly conserved single polypeptide expressed in all mammal eukaryotic cells, has been identified to mediate myocardial dysfunction in vitro once released from the nuclei of cardiomyocytes...

BACKGROUND: For investigating the relationship of frailty with physical, psychological, and social conditions on pathways, the frailty definition should ideally exclude these conditions. Based on the frailty phenotype, 2 candidate physical frailty specifications or instruments with 3 indicators, namely slowness, weakness, and exhaustion, and 4 indicators with addition of weight loss were previously developed, and had their construct and concurrent validity demonstrated. OBJECTIVE: This study seeks to evaluate the predictive validity of 2 candidate physical frailty specifications with respect to death, functional impairment, and poor quality of life in older people...

BACKGROUND: To date, not much is known about the psychological and motivational factors underlying technology use in late life. What are the interindividual determinants that lead older adults to invest in using technological innovations despite the age-related physiological changes that impose challenges on behavioral plasticity in everyday life? OBJECTIVE: This research explores interindividual differences in subjective technology adaptivity - a general technology-related motivational resource that accounts for technology use in late life...

This brief review on perceived control and aging is organized according to 3 perspectives of research involving description, explanation, and modification. An extensive body of literature has utilized cross-sectional and correlational methods to describe the sociodemographic variations and outcomes associated with perceived control. This work has focused on differences in perceived control as a function of age, sex, education, socioeconomic status, and culture and has identified positive associations with many aging-related outcomes involving health and well-being...

OBJECTIVE: Researcher-defined criteria for successful aging (SA) have been criticized for their limited perspective and failure to acknowledge subjective perceptions of older individuals. We assessed the extent to which older individuals consider specific factors, which they had suggested, to be important in defining SA. The present study had 2 objectives: (a) to develop a brief multidimensional questionnaire for assessing SA and to evaluate its psychometric properties; and (b) to examine age associations with each dimension of SA...

BACKGROUND: Impairment of physical function is a major indicator of frailty. Functional performance tests have been shown to be useful for identification of frailty in older adults. However, these tests are often not translatable into unsupervised and remote monitoring of frailty status at home and/or community settings. OBJECTIVE: In this study, we explored daily postural transition quantified using a chest-worn wearable technology to identify frailty in community-dwelling older adults...

BACKGROUND: An important aspect of successful aging is maintaining the ability to solve everyday problems encountered in daily life. The limited evidence today suggests that everyday problem solving ability increases from young adulthood to middle age, but decreases in older age. OBJECTIVES: The present study examined age differences in the relative contributions of fluid and crystallized abilities to solving problems on the Everyday Problems Test (EPT). We hypothesized that due to diminishing fluid resources available with advanced age, crystallized knowledge would become increasingly important in predicting everyday problem solving with greater age...

Vian Azzu, Teresa G Valencak
The mouse has rapidly become the mammalian model organism of choice in ageing research due to its relatively short lifespan, the proximity of its genome and physiology to humans, and most importantly due to its genetic pliability and the availability of mutant strains. Mouse models have provided great insights into the ageing process, which in its broadest sense is the progressive decline of body functions over time. In this mini-review, we briefly cover the historical views on the link between ageing and metabolic rate, highlight genetically modified transgenic mouse models of extended lifespan, discuss endocrine pathways linked to senescence and ageing, and then examine pathways by which caloric restriction is postulated to result in longevity...

BACKGROUND: Light interventions typically exert their mood-related effects during morning bright light exposures over several weeks. Evidence about immediate ambient room light effects on depressed individuals is still sparse. OBJECTIVE: The present study aimed at examining the acute effects of a single moderately bright room light exposure on mood, and behavioural and cardiac stress reactions of mildly depressed geriatric inpatients during a short cognitive stimulation and while resting...

BACKGROUND: In aging populations with an ever-growing burden of risk factors such as obesity, diabetes, and hypertension, chronic kidney disease (CKD) is on the rise. However, little is known about its exact prevalence among elderly adults, and often albuminuria is not included in the definition of CKD. Moreover, novel equations for the estimated glomerular filtration rate (eGFR) have recently emerged, which have not been applied comprehensively to older adults. Data on CKD awareness among the elderly are sparse...

BACKGROUND: The human immunodeficiency virus (HIV) is associated with cognitive impairment, and loneliness is associated with cognitive decline in old age. Older Black adults with HIV may be at particular risk of loneliness due to stigma and lack of social resources. OBJECTIVE: We tested the hypotheses that (1) older Black adults with HIV would show greater loneliness than older White adults with HIV, and (2) greater loneliness among older Black adults with HIV would be associated with poorer cognitive function...

BACKGROUND: The increase in life expectancy is accompanied by a growing number of elderly subjects affected by chronic comorbidities, a health issue which also implies important socioeconomic consequences. Shifting from hospital or community dwelling care towards a home personalized healthcare paradigm would promote active aging with a better quality of life, along with a reduction in healthcare-related costs. OBJECTIVE: The aim of the SMARTA project was to develop and test an innovative personal health system integrating standard sensors as well as innovative wearable and environmental sensors to allow home telemonitoring of vital parameters and detection of anomalies in daily activities, thus supporting active aging through remote healthcare...

BACKGROUND: Social network research has become central to studies of health and aging. Its results may yield public health insights that are actionable and improve the quality of life of older adults. However, little is known about the social networks of older immigrant adults, whose social relationships often develop in the context of migration, compounded by cultural and linguistic barriers. OBJECTIVES: This report aims to describe the structure, composition, and emotional components of social networks in the Chinese aging population of the USA, and to explore ways in which their social networks may be critical to their health decision-making...

Smart multifunctional materials can play a constructive role in addressing some very important aging-related issues. Aging affects the ability of older adults to continue to live safely and economically in their own residences for as long as possible. Thus, there will be a greater need for preventive, acute, rehabilitative, and long-term health care services for older adults as well as a need for tools to enable them to function independently during daily activities. The objective of this paper is, thus, to present a comprehensive review of some potential smart materials and their areas of applications to gerontology...

Dietary restriction (DR) is best known for extending lifespan in experimental model organisms, but also increases resistance to a variety of clinically relevant stressors, including those associated with surgery. Extended periods of DR, lasting months to years, are required for optimal longevity benefits in rodents, but short-term dietary preconditioning (less than 1 week) remarkably protects from acute injury. Here, we discuss recent advances in our understanding of the mechanistic basis of short-term DR and fasting in the context of surgical stress resistance, including upstream amino acid sensing by the GCN2 and mTORC1 pathways, and downstream effector mechanisms including increased insulin-dependent prosurvival signaling and elevated endogenous hydrogen sulfide production...

The Zika virus (ZIKV) outbreak in French Polynesia, in 2013, and in Brazil, in 2015, was correlated with neurological complications, which comprised, among others, congenital microcephaly and Guillain-Barré syndrome (GBS), which includes a group of acute autoimmune neuropathies generally reported after respiratory or gastrointestinal infectious diseases. Despite being relatively rare, the incidence rate of GBS rises with age, which makes GBS more frequent in the elderly, in whom it is also a more severe disease with slower recovery than in younger patients...

The recent advent of genome and epigenome editing technologies has provided a new paradigm in which the landscape of the human genome and epigenome can be precisely manipulated in their native context. Genome and epigenome editing technologies can be applied to many aspects of aging research and offer the potential to develop novel therapeutics against age-related diseases. Here, we discuss the latest technological advances in the CRISPR-based genome and epigenome editing toolbox, and provide insight into how these synthetic biology tools could facilitate aging research by establishing in vitro cell and in vivo animal models to dissect genetic and epigenetic mechanisms underlying aging and age-related diseases...
