Com o objetivo de identificar o conhecimento sobre o envelhecimento do sistema tegumentar, caracterizado como senescência, apesar da ocorrência de diversas patologias na pele a ela associadas, este trabalho utilizou o método da revisão integrativa da literatura (Ganong, 1987). A análise dos artigos foi quantitativa e qualitativa, firmada num roteiro de coleta de dados seguindo seis critérios de identificação a seguir: autor; profissão e local de atuação; país de origem e periódicos; características da amostra estudada; tipos de modelos do estudo; objetivos da pesquisa; conhecimentos sobre o tema definido para estudo. A amostra foi composta de cinqüenta e sete publicações, sendo a maioria na língua inglesa. Os objetivos definidos pelos pesquisadores envolveram: níveis de elastina, funções da pele nos idosos, avanços na genética molecular, acúmulo de apagamento DNA de mitocôndrias com envelhecimento da pele, níveis de ácido hialurônico, envelhecimento cutâneo e dermatoses geriátricas, colágeno na pele e massa óssea durante o envelhecimento, e manchas de pessoas que foram radiadas. Como o envelhecimento da pele está associado não só ao critério cronológico, mas, também, a aspectos externos relativos ao modo de vida das pessoas...

Com o envelhecimento há aumento da incidência de problemas gastrointestinais relacionados com a motilidade intestinal. A atividade física pode promover mudanças funcionais significantes, atuando como minimizadora dos efeitos deletérios do processo de envelhecimento. O controle das funções gastrointestinais é feito pelo sistema nervoso entérico composto por um conjunto de neurônios intramurais, entretanto, nada se sabe sobre os efeitos da atividade física regular sobre o envelhecimento dos neurônios mioentéricos. Desta forma, o presente estudo teve por objetivo analisar as alterações quantitativas e morfométricas causadas pelo envelhecimento e pela atividade física nos neurônios mioentéricos NADH e NADPH-diaforase positivos do duodeno de ratos de meia idade. E ainda verificar em microscopia de luz e eletrônica de transmissão as possíveis alterações na morfologia e ultraestrutura do plexo, e na espessura da túnica muscular. Para tanto, foram utilizados 45 ratos Wistar distribuídos em três grupos: C (seis meses de idade sedentário), S (doze meses de idade sedentário) e T (doze meses de idade submetidos à atividade física). Os animais do grupo T realizaram atividade física cinco vezes por semana, durante seis meses. Nenhuma alteração morfológica foi encontrada entre os grupos...

Osteoporose é a doença osteometabólica mais comum na população idosa. É definida como redução difusa da qualidade óssea que surge por um desbalanço entre a reabsorção e a formação óssea. Vários fatores etiológicos acontecem juntos levando à redução das proteínas ósseas, entre eles: deficiência hormonal, senilidade, subnutrição e imobilização. Um fator etiológico que, além dos processos de mutação, leva a alteração da estrutura do colágeno no processo de envelhecimento é o ageing, que se caracterizado por mudanças estruturais na matriz extracelular e virtualmente atinge todos os tecidos e sistemas orgânicos. Mudanças nas ligações cruzadas têm sido considerada como o papel principal do ageing e essas ocorrem através de 2 principais maneiras: a primeira é um processo enzimático pela ação da lisil oxidase e a segunda é um processo não-enzimático e recebe o nome de glicação. Essa última envolve reação da glicose com arginina (Arg) e lisina (Lys) sendo a principal causa de disfunção dos tecidos colágeno na idade avançada. No ageing há hidroxilação da lisina (Lys) levando modificação nas ligações cruzadas, o que gera uma estrutura de colágeno alterada. Além disso, a alteração em especial da arginina (Arg) afeta a crucial interação célula-matriz envolvendo motifs como o RGD (Arg-Gly-Asp)...

Ageing is a complex and multi-factorial process that results in the progressive accumulation of molecular alterations that disrupt different cellular functions. The budding yeast Saccharomyces cerevisiae is an important model organism that has significantly contributed to the identification of conserved molecular and cellular determinants of ageing. The nutrient-sensing pathways are well-recognized modulators of longevity from yeast to mammals, but their downstream effectors and outcomes on different features of ageing process are still poorly understood. A hypothesis that is attracting increased interest is that one of the major functions of these “longevity pathways” is to contribute to the maintenance of the proteome during ageing. In support of this hypothesis, evidence shows that TOR/Sch9 and Ras/PKA pathways are important regulators of autophagy that in turn are essential for healthy cellular ageing. It is also well known that mitochondria homeostasis and function regulate lifespan, but how mitochondrial dynamics, mitophagy and biogenesis are regulated during ageing remains to be elucidated. This review describes recent findings that shed light on how longevity pathways and metabolic status impact maintenance of the proteome in both yeast ageing paradigms. These findings demonstrate that yeast remain a powerful model system for elucidating these relationships and their influence on ageing regulation.

In this paper we focused on the experiences of ageing from the perspective of elderly people. Our main aims were to explore their perceptions and representations about the ageing experience and to analyse if their conceptions are closer to positive social representations of active ageing or to ageist social assumptions. Thirty-five females (mean age of 80 years) and seven males (mean age of 73 years) participated in this study, recruited in a network of institutions run by the city council of Setubal. Data collection was conducted with structured interviews and the obtained transcriptions were submitted to qualitative thematic analysis. With this analytic approach it was possible to identify dominant themes in participants discourses. Results show that elderly perceive and represent the process of ageing according to a binary perspective, displaying both positive and negative dimensions. Even if the ageing experience is described according to a positive perspective, it is also anchored on ageist social constructions. Thus the positive social representations of ageing expressed through active ageing discourses are still not fully assimilated and integrated on people s self-perceptions and identities.

Objective: We examined whether midlife body mass index (BMI) and waist circumference (WC) predict successful ageing. Design and Methods BMI/WC were assessed in 4869 persons (mean age 51.2, range 42–63 in 1991/93) and survival and successful ageing (alive, no chronic disease at age >60 years, not in the worst age- and sex-standardized quintile of cognitive, physical, respiratory, and cardiovascular, and mental health) ascertained over a 16-year follow-up, analysed using logistic regression adjusted for socio-demographic factors and health behaviours. Results: 507 participants died, 1008 met the criteria for successful ageing. Those with BMI≥30 kg/m2 had lower odds of successful ageing (Odds Ratio (OR)=0.37; 95% Confidence Interval (CI): 0.27, 0.50) and survival (OR=0.55; 95% CI: 0.41, 0.74) compared to BMI between 18.5–25 kg/m2. Those with a large waist circumference (≥102/88 cm in men/women) had lower odds of successful ageing (OR=0.41; 95% CI: 0.31, 0.54) and survival (OR=0.57; 95% CI: 0.44, 0.73) compared to those with a small waist (<94/80 cm in men/women). Analysis with finer categories showed lower odds of successful ageing starting at BMI ≥23.5 kg/m2 and waist circumference 82/68 cm in men/women. Conclusions: Optimal midlife BMI and waist circumference for successful ageing might be substantially below the current thresholds used to define obesity.

Over the past three decades, the United Nations (UN) has slowly devoted increasing attention to global ageing. Concern for individually based welfare or health-care programs for older people in developed countries has progressed to also consider the contributions of older people and implications of ageing for socioeconomic advancement in developing countries, including those in Asia Oceania. These shifts are evident in the International Plans of Action on Ageing from Vienna in 1982 to Madrid in 2002; recent 10-year reviews of the Madrid Plan; and current advocacy for inclusion of ageing in the influential UN Millennium Plan post-2015. Australia has demonstrated progressive policies and contributed to ageing developments by the UN, International Federation on Ageing the World Health Organization and the International Association of Gerontology. Key ideas driving further action are the importance of valuing people at all ages, addressing inequalities over the life-course and implementing human rights approaches to ageing.

Current mainstream models of successful ageing have received criticism in the literature, especially Rowe and Kahn’s (1987) model, the most widely accepted theory of successful ageing in gerontology. A key aim for the present study is to challenge the key mainstream theories of successful ageing. This thesis asks whether the dominant perspectives on successful ageing can be challenged by directly consulting older women about how they see the roles of religion and spirituality in ageing well and by unpacking specific problems identified in the literature. Criticisms include the lack of consultation with ol successful ageing researchers. A second issue is the negative way that the last phase of life, or ‘Fourth Age’ (Laslett, 1989), is represented in successful ageing theories and also in the field of gerontology and society generally. The leading models of successful ageing from Rowe and Kahn and Baltes and Baltes (1990) postulate that successful ageing is contingent on certain capacities and that successful ageing comes to an end when health and good functioning, or the capacity to employ adaptive strategies, fails. Hence life in very old age is represented as a picture of loss and decline with no positive prospects. A third criticism relates to the lack of inclusion of religious and spiritual affiliations which may be important resources for psychological...

Australia’s older population has become increasingly diversified in terms of country of origin and ethnicity. The overall aim of the thesis was to critically explore ageing well in an immigrant community by examining the intersection of the Western value system of successful ageing and the Eastern value system of filial piety through the lens of acculturation. In particular, the aim of the present research was to investigate attitudes and beliefs towards ageing and well-being within the context of successful ageing; and the needs and expectations within the context of filial piety among Anglo-Australians and Chinese immigrants. By focusing on the older Chinese community, an under-studied group that is emerging in contemporary Australia, the present research gave a voice to their values and what they perceived as appropriate and relevant as they age away from their country of origin. Using a mixed methods research design, the first phase comprised of a qualitative research component. Interpretative Phenomenological Analysis (IPA) was used to identify and explore themes gathered through semi-structured interviews with 21 participants, 11 Anglo-Australians and 10 Chinese-Australians, aged 55 to 78 years. The present research also explored the issue of establishing rigour in qualitative research within the context of IPA and noted that the use of inter-rater reliability is questionable because it does not consider researcher subjectivity...

The ageing of populations is an unavoidable and irreversible global phenomenon. Ageing in developed countries occurred gradually over a relatively long period of time, while ageing in developing countries including Sri Lanka has been more rapid. The rapid decline of fertility and mortality rates along with migration in Sri Lanka, have reshaped the age-sex structure of the population. Sri Lanka’s rapidly ageing population has important social-economic implications and real challenges for government and older people themselves. The ageing process has an important relationship with the changing nature, structure and the function of the family which has been occurring simultaneously in Sri Lanka. The Sri Lankan elderly have traditionally been almost totally dependent on family support, and a key policy question is whether the transition from traditional to modern family will change intergenerational relationships. The conceptual framework of the study, based largely on the work of Caldwell (1982) and Hugo (1997) focuses on changes in the intergenerational transfer of wealth and its implications for ageing populations. The study argues that the changes in the direction of wealth flows associated with changing role of the family, has influenced the wellbeing of the aged population. The study uses a mixed methodology based primarily on surveys of 300 elderly households and 150 control households and a wide range of quantitative and qualitative information. This study examines the effects of the changing role of the family on the ageing population in Sri Lanka. Examination of the timing of the onset of ageing and its process...

Der Alterungsprozess kann in zwei Qualitäten unterteilt werden, intrinsisches und extrinsisches. Während beim intrinsischen Altern auch genannt chronologisches Altern vermehrt genetische und endogene Stoffwechselprozesse eine Rolle spielen, kann beim extrinsischen Altern die ultraviolette Strahlung eine Ursache darstellen. Da es sich bei der Alterung um langwierige Prozesse handelt sind genetische Erkrankungen mit vorzeitiger Alterung wichtige Modellsysteme. Hierzu gehört auch die Erkrankung CockayneSyndrom, die einen Defekt in der Nukleotidexzisionsreparatur aufweist. Am Beispiel des CockayneSyndroms konnten wir und andere zeigen, dass sowohl extrinsische als auch intrinsische Alterungsprozesse beobachtet werden können. Weiter zeigte sich bei dieser Erkrankung, dass Mutationen der mitochondrialen (mt) DNA vermehrt im Alterungsprozess zu beobachten sind und dies vor allem im subkutanen Fett der Haut zu beobachten ist, das alterabhängig reduziert ist. Aus diesen Vorarbeiten heraus haben wir untersucht, wo über den Körper normaler Mäuse verteilt Mutationen der mt DNA in Epidermis, Dermis und subkutanem Fett vermehrt zu beobachten sind und ob dies über oxidativen Stress zum Verlust des subkutanen Fettgewebes führt, wie in Vorarbeiten untersucht. In der Tat konnten wir zeigen...

This paper takes a differential demographic change in six rural settlement categories within rural and regional Australia as the starting point for the measurement of differential ageing using a Relative Ageing Index which compares ageing in sub-populations with the national norm. The spatial units employed are 412 rural communities, approximated by social catchments each consisting of a country town and its surrounding dispersed population. The study covers the period from 1981 to 2006 and includes the rural areas of New South Wales, Victoria, and South Australia, excluding major cities, peri-urban areas, and the remote rangelands. It examines demographic change and differential ageing in a selection of the rural settlement categories recommended for further analysis in the report of the ‘Demographic Change and Liveability Panel’, one of three advisory panels established in 2010 by the then Commonwealth Government seeking to develop a sustainable population strategy for Australia. Ageing profiles are produced for the whole study area, for the individual rural settlement categories, and for the urban and rural components within each category separately. Results show that differential ageing is least advanced in the ‘regional cities’...

Background: The global trend of increased life expectancy and increased prevalence of chronic and degenerative diseases will impact on health systems. To identify effective intervention and prevention strategies, greater understanding of the risk factors for and cumulative effects of chronic disease processes and their effects on function and quality of life is needed. The Busselton Healthy Ageing Study aims to enhance understanding of ageing by relating the clustering and interactions of common chronic conditions in adults to function. Longitudinal (3–5 yearly) follow-up is planned. Methods/design: Phase I (recruitment) is a cross-sectional community-based prospective cohort study involving up to 4,000 'Baby Boomers’ (born from 1946 to 1964) living in the Busselton Shire, Western Australia. The study protocol involves a detailed, self-administered health and risk factor questionnaire and a range of physical assessments including body composition and bone density measurements, cardiovascular profiling (blood pressure, ECG and brachial pulse wave velocity), retinal photography, tonometry, auto-refraction, spirometry and bronchodilator responsiveness, skin allergy prick tests, sleep apnoea screening, tympanometry and audiometry, grip strength...

Population ageing is a fact in both developed and developing countries. The concern about population ageing largely arises from the combination of a greater number of older people requiring greater amounts of healthcare services and pensions, and relatively fewer people working to pay for them. Oral health and dental care are important aspects of health and health care. Lower rates of edentulism and an ageing population mean that older people will feature more prominently in dental services. Traditionally, economic studies of ageing have focused on the fiscal implications of ageing, projecting the increased burden on health and welfare services that accompanies ageing. It assumed that ageing is the major driver of recent changes and those past trends will simply be amplified by faster population ageing in the future. Less work has been done to understand other past drivers of increased healthcare spending and their implications for the future. The conclusion of these reports is usually that population ageing is unaffordable with current policy settings. They have proposed policies to deal with population ageing which focused on increasing workforce participation and worker productivity to increase the tax base and reducing entitlements. However...

Research into the concept of successful ageing, or ageing well, within the context of migration has become significant in cross-cultural gerontology and psychology. Given that attributes of successful ageing had been identified in published Western literature, it has been argued that these attributes commonly reflect Western perceptions. This study examined the 20 attributes identified by Phelan, Anderson, LaCroix & Larson (2004) as important to successful ageing, comparing the views of older adults with researchers' definitions. The sample consisted of 152 Anglo-Australians and 116 Chinese-Australians: English speaking (n = 68) and Chinese speaking (n = 48). Anglo-Australians and Chinese-Australians rated 13 and 14 of the 20 successful ageing attributes as important, respectively. Results also revealed that Anglo-and Chinese-Australians differed significantly on four successful ageing attributes. For Chinese speaking Chinese-Australians, heredity was rated as important to successful ageing compared to their English speaking and Anglo-Australian counterparts. The research contributes to greater understanding of the way in which people from different backgrounds view quality of life so as to better support positive ageing in minority groups.; Joanne Tan...

BACKGROUND: A large number of longitudinal studies of population-based ageing cohorts are in progress internationally, but the insights from these studies into the risk and protective factors for cognitive ageing and conditions like mild cognitive impairment and dementia have been inconsistent. Some of the problems confounding this research can be reduced by harmonising and pooling data across studies. COSMIC (Cohort Studies of Memory in an International Consortium) aims to harmonise data from international cohort studies of cognitive ageing, in order to better understand the determinants of cognitive ageing and neurocognitive disorders. METHODS/DESIGN: Longitudinal studies of cognitive ageing and dementia with at least 500 individuals aged 60 years or over are eligible and invited to be members of COSMIC. There are currently 17 member studies, from regions that include Asia, Australia, Europe, and North America. A Research Steering Committee has been established, two meetings of study leaders held, and a website developed. The initial attempts at harmonising key variables like neuropsychological test scores are in progress. DISCUSSION: The challenges of international consortia like COSMIC include efficient communication among members...

Introduction The demographic epidemiologic transition is a worldwide phenomenon and it is present both in the developed countries and increasingly in the developing ones. The population estimates in the studied countries show that Portugal is nowadays in the list of the oldest countries in the world and in Brazil the “ageing of the top” will occur up to 2025 occupying the 6th elderly population of the world, in absolute terms. Methods The aim of this study was to analyze comparatively Life Quality between the senior citizens who participate in the Public Physical Activity Programs at Nisa, Portugal (Program Activ Sénior) and Florianópolis, Brazil (Programa Floripa Ativa). A transversal descriptive study was carried out including 258 senior citizens, both genders, from October to December 2011 using the Brazilian and Portuguese versions of the Short Form 36 questionnaire. The statistics tests performed were Student’s t-teste, ANOVA, Kruskal Wallis test and K-S test. Results The global Cronbach’s alpha was 0.72 for the Physical and 0.73 for the Mental Component. Descriptive analysis showed that the subjects' average age was 69,56 years old (PD:+/- 5,74 years) and that most of them were women (84,8%). The best scores for both cities/countries were obtained for the Mental Component: Social Function (83...

This is the final published version of the article. It first appeared at http://www.biomedcentral.com/1471-2377/14/204.; Background As greater numbers of us are living longer, it is increasingly important to understand how we can age healthily. Although old age is often stereotyped as a time of declining mental abilities and inflexibility, cognitive neuroscience reveals that older adults use neural and cognitive resources flexibly, recruiting novel neural regions and cognitive processes when necessary. Our aim in this project is to understand how age-related changes to neural structure and function interact to support cognitive abilities across the lifespan. Methods/Design We are recruiting a population-based cohort of 3000 adults aged 18 and over into Stage 1 of the project, where they complete an interview including health and lifestyle questions, a core cognitive assessment, and a self-completed questionnaire of lifetime experiences and physical activity. Of those interviewed, 700 participants aged 18-87 (100 per age decile) continue to Stage 2 where they undergo cognitive testing and provide measures of brain structure and function. Cognition is assessed across multiple domains including attention and executive control, language...

The wine brandies, as other alcoholic beverages, must be kept for several months (minimum of six months according to the European legislation) in wooden barrels, in order to achieve the minimum quality, before its consumption. However, the high costs related to ageing in wooden barrels have lead to the search of alternative technologies, such as the use of wood fragments, in order to accelerate the ageing process. In this work, the same wine brandy from Lourinhã was used to fill wooden barrels and stainless steel tanks with wood tablets or wood staves. These three ageing systems were studied with Limousin oak wood (Quercus robur L.) and Portuguese chestnut wood (Castanea sativa Mill.), with two replicates of each modality. The brandies were evaluated by sensory descriptive analysis during a period of 30 months. Colour, olfactory and gustatory attributes, previously generated by the tasting panel, were analysed. The results showed a significant effect of the ageing system on few sensory attributes. However, the most discriminant factors were the wood botanical species and the ageing time, which affected significantly several sensory attributes. Concerning the ageing system, the brandies aged in the presence of wood tablets presented lower intensity of the attribute golden and higher intensities of the attributes topaz...
