A specific protein-enriched enteral formula decreases cortisolemia and improves plasma albumin and amino acid concentrations in elderly patients

Background: Old age is associated with an involuntary and progressive but physiological loss of muscle mass. The aim of this study was to evaluate the effects of exclusive consumption for 6 months of a protein-enriched enteral diet with a relatively high content of branched-chain amino acids on albuminemia, cortisolemia, plasma aminoacids, insulin resistance, and inflammation biomarkers in elderly patients. Methods: Thirty-two patients from the Clinical Nutrition Outpatient Unit at our hospital exclusively consumed a protein-enriched enteral diet for 6 months. Data were collected at baseline and at 3 and 6 months on anthropometric and biochemical parameters and on plasma concentrations of amino acids, cortisol,adrenocorticotropic hormone, urea, creatinine, insulin resistance, and inflammation biomarkers. Results: The percentage of patients with albumin concentration below normal cut-off values decreased from 18% to 0% by the end of the study. At 6 months, concentrations of total plasma (p = 0.008) and essential amino acids(p = 0.011), especially branched-chain amino acids (p = 0.031), were higher versus baseline values, whereas 3-methylhistidine (p = 0.001), cortisol (p = 0.001) and adrenocorticotropic hormone (p = 0.004) levels were lower. Conclusions: Regular intake of specific protein-enriched enteral formula increases plasma essential amino acids, especially branched-chain amino acids, and decreases cortisol and 3-methylhistidine, while plasma urea and creatinine remain unchanged.

Representaciones y significados acerca de la vejez institucionalizada

Este trabajo de investigación se enmarca en los estudios dedicados al conocimiento del significado que se le atribuye a la vejez en nuestra sociedad. El ámbito de interés se centra en la vida de las personas mayores dentro y fuera de las instituciones geriátricas con el objeto de comprender en qué medida estos factores pueden llegar a condicionar el imaginario acerca de la vejez. Más específicamente la idea central, que orienta la investigación y delimita claramente el tema de trabajo, se sintetiza en la siguiente pregunta clave: ¿cómo incide la institucionalización de los ancianos y las ancianas en la concepción y autopercepción de la vejez?

Senescence in cell oxidative status in two bird species with contrasting life expectancy.

Oxidative stress occurs when the production of reactive oxygen species (ROS) by an organism exceeds its capacity to mitigate the damaging effects of the ROS. Consequently, oxidative stress hypotheses of ageing argue that a decline in fecundity and an increase in the likelihood of death with advancing age reported at the organism level are driven by gradual disruption of the oxidative balance at the cellular level. Here, we measured erythrocyte resistance to oxidative stress in the same individuals over several years in two free-living bird species with contrasting life expectancy, the great tit (known maximum life expectancy is 15.4 years) and the Alpine swift (26 years). In both species, we found evidence for senescence in cell resistance to oxidative stress, with patterns of senescence becoming apparent as subjects get older. In the Alpine swift, there was also evidence for positive selection on cell resistance to oxidative stress, the more resistant subjects being longer lived. The present findings of inter-individual selection and intra-individual deterioration in cell oxidative status at old age in free-living animals support a role for oxidative stress in the ageing of wild animals.

The Farm, the city, and the emergence of social security

We study the social, demographic and economic origins of social security. The data for the U.S. and for a cross section of countries suggest that urbanization and industrialization are associated with the rise of social insurance. We describe an OLG model in which demographics, technology, and social security are linked together in a political economy equilibrium. In the model economy, there are two locations (sectors), the farm (agricultural) and the city (industrial) and the decision to migrate from rural to urban locations is endogenous and linked to productivity differences between the two locations and survival probabilities. Farmers rely on land inheritance for their old age and do not support a pay-as-you-go social security system. With structural change, people migrate to the city, the land loses its importance and support for social security arises. We show that a calibrated version of this economy, where social security taxes are determined by majority voting, is consistent with the historical transformation in the United States.

Mainmise sur l'état social : mobilisation patronale et caisse de compensation en Suisse (1908-1960)

Qui sait qu'en Suisse, les associations patronales mettent en oeuvre l'Etat social ? Qui sait que associations organisent la majorité des caisses de compensation, dont la fonction principale est de collecter les cotisations et de payer les rentes de l'Assurance-vieillesse et survivants ? Qui connaît ces caisses par lesquelles transitent les milliards de l'Etat social ? L'objectif de cette thèse consiste à comprendre les raisons qui ont poussé le patronat helvétique à mettre en oeuvre les politiques de protection sociale, dont il a pourtant toujours essayé de limiter le développement. Résoudre ce paradoxe implique de se pencher sur près d'un siècle d'histoire mêlée du patronat et des politiques sociales. Ce travail retrace, sur la base d'archives privées et publiques souvent inédites, les raisons qui ont poussé les patrons à créer les premières caisses de compensation dans l'entre-deux-guerres, puis à imposer cette forme d'organisation pour l'aide aux soldats mobilisés (autour de 1940) et l'Assurance- vieillesse et survivants (autour de 1948). Il étudie également comment les associations patronales sont parvenues à défendre leurs caisses jusqu'à aujourd'hui, contre ceux qui dénonçaient l'irrationalité de l'existence d'une centaine de caisses de compensation publiques et privées concurrentes pour mettre en oeuvre un seul système d'assurances sociales. Cette recherche amène deux grands résultats. D'une part, elle propose une histoire originale des politiques sociales en Suisse. Le prisme des caisses de compensation patronales contribue en effet à interroger notre compréhension de l'histoire des politiques de protection sociale, dans laquelle on sous-estime parfois l'importance des conflits pour fixer les frontières entre formes de protection publique et privée. D'autre part, ce travail présente une histoire inédite de l'action collective des patrons dans les régulations du travail au sens large. A travers les caisses de compensation, c'est en effet à réaliser une histoire de l'Union centrale des associations patronales suisses que je me suis aussi attelé. Faute de parvenir à empêcher tout développement des politiques sociales, les patrons ont fait en sorte d'acquérir sur ces politiques une forme de mainmise. Entre histoire des politiques sociales et histoire du patronat, ce travail tente d'expliquer comment les caisses de compensation y ont contribué. Who knows that, in Switzerland, employers' associations implement the best known policies constituting the welfare state? Who knows that the equalization funds, (Caisses de compensation / Ausgleichskassen), organized by employers' associations or by the Swiss Cantons, are responsible for pooling payroll deductions and for paying benefits of the Swiss public pay-as-you-go, old-age insurance and many other branches of the welfare policies? Who knows these caisses de compensation that channel the monies dedicated to the financing of the Welfare state ? The main objective of this research is to understand the reasons why Swiss employers do implement such welfare policies that they usually reject for political reasons. In order to solve this puzzle, this research investigates half of a century of the connected histories of welfare policies and employers' collective action. It also investigates, based on public and private archive records, how employers founded the first caisses in the Interwar period, and imposed them to organize the main developments of the Welfare state during the Second World War. The research also underlines how employers defended their caisses de compensation against those questioning the rationality of this fragmented system aiming to implement one single set of public welfare through one hundred competing private and public caisses de compensation. This research highlights two main results. On the one hand, it helps to improve our understanding of the history of the welfare policies in Switzerland. Underlining the role of the caisses de compensation helps to highlight the importance of the interplay of public and private actors regarding social polices. On the other hand, this research charts a pioneering history of Swiss' employers' collective action regarding labor issues. Because they could not prevent all public welfare policy, employers achieved a form of stranglehold (mainmise) on the welfare State. Halfway between social policy and employers' associations' history, this research try to reveal how their caisses de compensation helped them in this objective.

Auditoria ètica en un centre d’atenció gerontològica per a gent gran amb dependència

L’ atenció a les persones grans en un establiment residencial ha experimentat una evolució important en els darrers anys: hem passat de l’atenció per beneficència dels ‘asils’ (marcada per un model clarament assistencialista, on l’usuari era un receptor passiu del servei) a l’atenció gerontològica integral (marcada per un model professionalitzat de servei, on l’usuari esdevé un consumidor actiu informat). Hi ha força acord que aquesta maduresa i professionalització ha de tenir en compte els aspectes ètics en l’atenció a la gent gran amb dependència, tant pel que fa a l’ètica assistencial pròpiament dita com a l’ètica de l’organització. Així, l’ètica esdevé un aspecte més a gestionar en aquestes organitzacions. Això requereix planificar com abordar els aspectes ètics en la dinàmica de l’organització, desenvolupar el treball planificat, avaluar els resultats i introduir millores a partir dels resultats obtinguts. En primer lloc hem de tenir identificats els temes ètics a contemplar en un centre gerontològic, que són diferents dels que es puguin plantejar en un centre sanitari, o en un centre educatiu, per exemple. Tot això, però, requereix un mètode i uns elements de mesura. Seria útil poder confeccionar una mena de radiografia de l’organització amb identificació del grau d’assoliment dels aspectes ètics. Es fa necessari disposar d’un instrument per mesurar la qualitat ètica en una residència. Una eina per assolir-ho seria l’auditoria ètica. Caldria disposar d’un model d’auditoria ètica adaptat a les necessitats d’un centre gerontològic d’atenció a persones grans amb dependència (popularment conegut per una ‘residència d’avis’). En aquest treball em proposo els següents objectius: 2.1.- Recerca documental per identificar sistemes d’auditoria ètica específics per a residències de gent gran; 2.2.- Si n’existeixen, fer una anàlisi i comparació dels diferents sistemes trobats, amb el punts forts i punts febles de cadascun d’ells i 2.3.- Valorar la seva idoneïtat en una residència per a gent gran

Well-being and the frailty process in later life: an evaluation of the effectiveness of downward social comparison

This article, which is based on a longitudinal study conducted with a cohort ofoctogenarians, examines downward social comparison and its effectiveness as an adjustment mechanism during the frailty process. First of all, a paradoxical stability of subjective well-being is to be observed: it remains stable over five years notwithstanding the general decline in health. Next, an analysis based on individual health trajectories reveals that downward social comparison is associated with the maintenance of a stable level of well-being, whereas, when it is not associated with well-being, the latter tends to vary.

Survey of aspergillosis in non-neutropenic patients in Swiss teaching hospitals.

Clin Microbiol Infect 2011; 17: 1366-1371 ABSTRACT: Invasive aspergillosis (IA) is a live-threatening opportunistic infection that is best described in haematological patients with prolonged neutropenia or graft-versus-host disease. Data on IA in non-neutropenic patients are limited. The aim of this study was to establish the incidence, disease manifestations and outcome of IA in non-neutropenic patients diagnosed in five Swiss university hospitals during a 2-year period. Case identification was based on a comprehensive screening of hospital records. All cases of proven and probable IA were retrospectively analysed. Sixty-seven patients were analysed (median age 60 years; 76% male). Sixty-three per cent of cases were invasive pulmonary aspergillosis (IPA), and 17% of these were disseminated aspergillosis. The incidence of IPA was 1.2/10 000 admissions. Six of ten cases of extrapulmonary IA affected the brain. There were six cases of invasive rhinosinusitis, six cases of chronic pulmonary aspergillosis, and cases three of subacute pulmonary aspergillosis. The most frequent underlying condition of IA was corticosteroid treatment (57%), followed by chronic lung disease (48%), and intensive-care unit stays (43%). In 38% of patients with IPA, the diagnosis was established at autopsy. Old age was the only risk factor for post-mortem diagnosis, whereas previous solid organ transplantation and chronic lung disease were associated with lower odds of post-mortem diagnosis. The mortality rate was 57%.

“IF ONLY I COULD�? ~ “THERE IS ALWAYS A LOOPHOLE"? Hope and hopelessness experienced by the severely depressive and nondepressive

The aim of this research was to structure a conceptual model of hope and hopelessness based on dictionary definitions, and to verify this model on the basis of the experiences of the severely depressive and non-depressive elderly. This research has produced a substantive theory of hope and hopelessness which is based on the experiences of the depressive and non-depressive elderly, and on the concept analysis of hope and hopelessness based on English dictionary definitions. The patients who participated in the research were 65 years old and older men and women (n=22) who had been admitted to a psychiatric hospital because of major depression, and another group: the non-depressive elderly (n=21), who were recruited from the pensioners’ clubs. The data were collected in interviews using the Clinical Assessment Tool, developed by Farran, Salloway and Clark (1990) and Farran, Wilken and Popovich (1992), and it produced 553 pages of written text, which were analysed using the ATLAS/ti programme. ATLAS/ti is a tool for analysing qualitative data and is based on Grounded Theory. The medical and nursing records of the depressive elderly completed source triangulation. The concept analysis of hope and hopelessness was made on the basis of the definitions of English dictionaries (n=103), using semantic analysis and the ATLAS/ti programme. The most important hope-promoting factors were human relations, health and managing in everyday living. Autonomy, self-determination and feeling of security were highly appreciated among the elderly. Hopelessness, on the other hand, was most often associated with the same factors: human relations, health and everyday living. Especially, losses of significant others were experienced as strongly hope-diminishing. Old age had brought freedom from duties concerning others, but now, when you finally had an opportunity to enjoy yourself, you could not accomplish anything; you were clasped in the arms of total inability, depression had come. The most obvious difference in the life course of the depressive and nondepressive elderly was the abundance of traumatic experiences in the childhood and youth of the depressive elderly. The continuous circulation of fearful thoughts was almost touchable, and suicidality was described in connection with these thoughts. You were afraid to be awake and also to go to sleep. Managing day by day was the goal. The research produced the Basic Social Process (BSP) of hope: achieving - maintaining - losing, which expresses a continuous balancing between Being without and Being with. The importance of the object of hope was combined with the amount of hope and disappointment. The process of approaching defined the realisation of hope and the process of withdrawal that of losing. Joy and security versus grief and insecurity defined the Being with and Being without. Two core categories were found. The first one “If only I could�? reflects lack of energy, lack of knowledge, lack of courage and lack of ability. The other one “There is always a loophole�? reflects deliberate tracing of possibilities and the belief in finding solutions, and managing.

Utilização de serviços de saúde por idosos vivendo na comunidade

O objetivo deste estudo foi analisar o padrão de utilização dos serviços de saúde por idosos cadastrados nos serviços públicos de Guarapuava-PR. Realizou-se inquérito domiciliar com 359 idosos selecionados por meio de amostragem estratificada proporcional. As entrevistas foram aplicadas entre janeiro e abril de 2010 no domicílio do idoso, utilizando-se as seções I e III do questionário BOAS (Brazil Old Age Schedule). Para apreciação aplicou-se análise de associação por meio do teste χ². Os serviços de saúde mais utilizados pelos idosos nos últimos três meses foram à consulta médica (49,6%) e os exames clínicos (38,4%). As mulheres utilizaram mais os serviços de saúde (p=0,0240); 55,6% dos idosos relataram não procurar os serviços dentários. Conclui-se que a população idosa é grande usuária dos serviços de saúde e a rede pública do município necessita se organizar frente a uma demanda crescente por procedimentos diagnósticos terapêuticos.

Social Security in Theory and Practice (II): Efficiency Theories, Narrative Theories, and Implications for Reform

166 countries have some kind of public old age pension. What economic forces create and sustain old age Social Security as a public program? Mulligan and Sala-i-Martin (1999b) document several of the internationally and historically common features of social security programs, and explore "political" theories of Social Security. This paper discusses the "efficiency theories", which view creation of the SS program as a full of partial solution to some market failure. Efficiency explanations of social security include the "SS as welfare for the elderly" the "retirement increases productivity to optimally manage human capital externalities", "optimal retirement insurance", the "prodigal father problem", the "misguided Keynesian", the "optimal longevity insurance", the "government economizing transaction costs", and the "return on human capital investment". We also analyze four "narrative" theories of social security: the "chain letter theory", the "lump of labor theory", the "monopoly capitalism theory", and the "Sub-but-Nearly-Optimal policy response to private pensions theory". The political and efficiency explanations are compared with the international and historical facts and used to derive implications for replacing the typical pay-as-you-go system with a forced savings plan. Most of the explanations suggest that forced savings does not increase welfare, and may decrease it.

Mental ill health in the elderly: medical students’ social representations in the United Kingdom

Objective This study aims to explore medical students’ social representations of mental ill health in older adults. Method It comprises an exploratory and qualitative investigation based on the theory of social representations. Two focus groups with pre-clinical medics (group 1, N=4; group 2, N=4) and 10 individual interviews with clinical medical students were conducted. Thematic analysis at a latent level explored meanings and differences between groups. Results Three overarching themes reflect participants’ representations of mental health problems in later life – mental ill health in old age, polarisation of care, and challenges to care. Primary health care appears as an important strategy to overcome barriers to mental health care in the community. Nevertheless, disqualifying representations, stigma and organization of services constitute the main challenges to quality mental health care in later life. Conclusion This paper highlights the need to address cultural and organizational barriers to promote quality care.

Prevalence of self-reported constipation in adults from the general population

OBJECTIVE To estimate the prevalence of self-reported constipation and associated factors in the general population of a Brazilian city. METHOD Secondary analysis of an epidemiological study, population-based, cross-sectional study, about bowel habits of Brazilian population. A total of 2,162 individuals were interviewed using two instruments: sociodemographic data and the adapted and validated Brazilian version of the "Bowel Function in the Community" tool. RESULTS There was a prevalence of 25.2% for the self-reported constipation, 37.2% among women and 10.2% among men. Stroke and old age were associated with constipation in the three statistical models used. CONCLUSION The prevalence found showed to be similar to the findings in the literature, although some associated factors obtained here have never been investigated.
