Examinations have been conducted with regard to how respective societies can accommodate the said changes in their health and social systems, but this research mostly focuses on more developed regions rather than lowerincome countries. This paper discussed the experience of ageing populations in developing economies, which comprise the majority of the global older population. They display a vastly different experience from high-income countries, especially when viewed within the level of world regions. The cases presented here were from Southeast Asian countries in order to have a wide range of examples in terms of differences in country-income categories. In lower and middle-income countries, there are older adults who: continue working as their primary income source, are nonmembers of pension systems, and provide intergenerational support rather than only receiving it. The COVID-19 pandemic situation was also included here, as policies were reformed to address current needs that highlighted the challenging situation of older adults. The populations of countries that have yet to age substantially, especially those in the least-developed regions, can utilise this paper's recommendations in order to prepare for changes in the age structures of their societies.","PeriodicalId":11008,"journal":{"name":"Current aging science","volume":"16 3","pages":"188-193"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10099197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aging is also accompanied by chronic low-grade inflammation. Both obesity and aging are associated with the development of metabolic diseases, leading to an increase in the senescent cell burden in multiple organs. Chronic low-grade inflammation of adipose tissue is one of the mechanisms implicated in the progression of these diseases. As a real endocrine organ, adipose tissue secretes many mediators and hormones (adipokines) to maintain metabolic homeostasis, and their dysfunction has been causally linked to a wide range of metabolic diseases. Dysfunctional adipose tissue participates in interorgan communication both by producing new signaling mediators and by transforming or disrupting signal mediators, reaching from other organs. In addition to obesity and similar metabolic diseases, this situation causes dysfunction in more organs in the aging process, and the complexity of the problem causes challenges in the diagnosis and treatment processes. This review aims to highlight recent developments and current information supporting the relationship between obesity and adipose tissue dysfunction with aging and the role of homeostatic and physio-pathological processes that mediate interorgan communication in aging progress. More understanding clearly of interorgan communication in the process of obesity and aging will facilitate the early diagnosis as well as the management of treatment practices in short- and long-term organ dysfunction.","PeriodicalId":11008,"journal":{"name":"Current aging science","volume":"16 2","pages":"97-111"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9505480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cell senescence exhibits a series of possible biochemical derangements concerning mitochondria, proteasome, genome and membranes. Research has shown that resilience can be acquired through hormesis, a set of conservative and adaptive processes based on biphasic doseresponse to specific mild stressors, such as fasting, intake of polyphenols, exercising, physical and chemical stress and mental engagement. These stimuli were shown to elicit beneficial cellular metabolic pathways, such as sirtuin activation, mechanistic target of rapamycin and insulin growth factor- 1 downregulation, nuclear related factor 2 upregulation and autophagy. The complex of these resilience-building processes plays a documented role in longevity. Mitochondria are regarded as one of the core actors of aging processes and represent the main target of hormetic approaches [mitohormesis]; furthermore, the influence of the mind on mitochondria, and thus on the balance of health and disease has been recently established, leading to the so-called mitochondria psychobiology. Hence, psychologic and physical stress that reflects on these organelles may be regarded as a relevant factor in cell senescence, and thus the proposed \"mitoresilience\" denomination may be pertinent within the biomedical science of aging. Finally, the quantification of individual resilience is becoming increasingly important in aging science, and the investigation of the autonomic nervous system through heart rate variability (HRV) proved to be a valid method to quantify this parameter. In conclusion, an integrated approach targeting hormetic pathways to improve psychophysical resilience (namely mitoresilience), supported by the monitoring of HRV, may represent a valuable option in longevity medicine.","PeriodicalId":11008,"journal":{"name":"Current aging science","volume":"16 1","pages":"25-32"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9277197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Resveratrol (RSV) is a polyphenolic compound that has been shown to act as an antioxidant in medical practice.Objective: To verify the antioxidant action of resveratrol (and its correlation with aging) in leukocytes from donors of different ages, mainly through the analysis of the three main enzymes of the antioxidant complex and the analysis of the SIRT1 signaling pathway.Methods: Luminol-dependent chemiluminescence assay was used to evaluate ROS and SIRT1. Antioxidant enzymes were evaluated by commercial kits. *p<0.05.Results: In all age groups, there was a reduction in reactive oxygen species (ROS) in cells stimulated with RSV. There was a positive correlation between its antioxidant effect and donor age. In younger individuals (20-39 years old), there was an increase in catalase activity in cells exposed to RSV. In the older groups (40-59 years old and 60-80 years old), RSV was able to increase the activity of the enzymes superoxide dismutase (SOD) and glutathione peroxidase (GPx). Through the analysis of SIRT1 it was possible to observe a silencing of the pathway in leukocytes treated with RSV during aging.Conclusion: RSV showed antioxidant activity in all age groups, although more pronounced in younger individuals. One of the mechanisms of action of the RSV is due to the increase in the activity of antioxidant enzymes, which varies according to the individual's age, especially through the modulation of important antioxidant pathways.","PeriodicalId":11008,"journal":{"name":"Current aging science","volume":"16 1","pages":"56-64"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9278020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early identification of people who are at risk for frailty is vital in preventing and minimizing its socio-economic consequences in low-resource countries like India. However, risk factors for frailty among Indian institutionalized older adults have been seldom explored.Objective: The objective of this study is to develop a prediction model for the risk of frailty among institutionalized older adults.Methods: This study adopted a case-control design, wherein institutionalized adults were categorized into frail and non-frail, using Fried's criteria. Individuals above 55 years of age who could follow instructions without severe motor and cognitive impairment and terminal illness were recruited from nine conveniently selected institutions. Socio-demographic, lifestyle, behavioral, and physical performance factors were evaluated by including hundred participants.Results: Among the fourteen independent variables, age, cognition, income, functional mobility, polypharmacy and presence of more than 3 comorbidities were significant in univariate analysis. But adjusted odds ratio showed a statistical significance for low educational status, low income, poor functional mobility, and presence of more than 3 co-morbidities only, hence they were used for developing the prediction model.Conclusion: Low education status, low income, poor functional mobility, and presence of more than 3 comorbidities were found to have a significant association with the risk of frailty. A model has been developed to predict the risk and early identification of frailty among institutionalized older adults.","PeriodicalId":11008,"journal":{"name":"Current aging science","volume":"16 1","pages":"33-39"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9277992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They were assessed for fall history, functionality, cognitive status, and several gait parameters in SSWS and FWS conditions.Results: Fallers differed from non-fallers in the SSWS, while such differences were not evidenced during the FWS. Cadence and stride width did not differ when living backgrounds were compared. Nursing home residents walked slower than their non-institutionalized peers, regardless of fall history or walking speed. Besides, binary logistic regression analysis showed that living in a nursing home, age, body mass index (BMI), mini-mental state examination (MMSE), and step width were related to falls in the SSWS. On the other hand, living in a nursing home, having a larger BMI and having low MMSE scores were fall predictors in the FWS.Conclusion: Fall occurrence can be identified by factors related to living in nursing homes, cognitive status, BMI, and gait parameters, at the SSWS.
