Thermotolerance and extended life-span conferred by single-gene mutations and induced by thermal stress.

We have discovered that three longevity mutants of the nematode Caenorhabditis elegans also exhibit increased intrinsic thermotolerance (Itt) as young adults. Mutation of the age-1 gene causes not only 65% longer life expectancy but also Itt. The Itt phenotype cosegregates with age-1. Long-lived spe-26 and daf-2 mutants also exhibit Itt. We investigated the relationship between increased thermotolerance and increased life-span by developing conditions for environmental induction of thermotolerance. Such pretreatments at sublethal temperatures induce significant increases in thermotolerance and small but statistically highly significant increases in life expectancy, consistent with a causal connection between these two traits. Thus, when an animal's resistance to stress is increased, by either genetic or environmental manipulation, we also observe an increase in life expectancy. These results suggest that ability to respond to stress limits the life expectancy of C. elegans and might do so in other metazoa as well.

Qualidade de vida relacionada à saude em mulheres com reações adversas após tratamento com quimioterapia para câncer de mama

Trata-se de estudo descritivo, exploratório, transversal, quantitativo, realizado com mulheres em tratamento quimioterápico para neoplasias de mama, em Aracaju-Sergipe-Brasil. O objetivo foi avaliar a qualidade de vida relacionada à saúde (QVRS) destas mulheres que apresentaram reações adversas pós quimioterapia. Foram utilizados instrumentos contendo dados sócio demográficos, clínicos e terapêuticos, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core30 e formulário de registro de toxicidades dos antineoplásicos. Na análise dos dados, foram utilizados análise descritiva, cálculos de percentual, teste de Shapiro-Wilk, coeficiente de correlação de Pearson ou de Spearman, teste de ANOVA ou Kruskal-Wallis. Os resultados mostraram dados de 206 mulheres, a partir da segunda sessão de quimioterapia, com média de idade de 53,1 anos, maioria procedente de Sergipe, com Carcinoma Ductal Infiltrante, estadiamento III. A maioria realizou cirurgia oncológica, não realizaram radioterapia devido à grande fila de espera, o protocolo de quimioterapia mais comum foi TAC (docetaxel, doxorrubicina e ciclofosfamida). Quanto às reações adversas, a maioria não apresentou alterações hematológicas e metabólicas no momento da coleta das informações, nas alterações funcionais, a fadiga foi presente em 80,8% dos casos, de forma moderada. Nas alterações gastrintestinais, diarreia, constipação, mucosite, náusea, vômito e dor abdominal foram citadas pela maioria. Nas alterações dermatológicas, a alopecia, hiperpigmentação na pele, alterações nas unhas, prurido na pele, descamação e eritema multiforme foram citadas pelas entrevistadas. Nas alterações cardiovasculares, hipotensão e HAS sobressaíram-se. Nas alterações neurológicas, neuropatia periférica, perda da audição e zumbido foram comuns. Os resultados da avaliação da QVRS foram analisadas à luz do referencial teórico de Ferrel et al. (1995) com os seguintes resultados: média do escore 76,01; escalas funcionais apresentaram escore baixo, com aspectos físico, emocional, cognitivo, funcional e social bastante afetados após o tratamento, o desempenho de papéis e função emocional foram os mais prejudicados; na escala de sintomas, os domínios mais prejudicados foram: dificuldades financeiras, fadiga e insônia. Na análise de correlação, o escore geral da QVRS apresentou correlação estatisticamente significante com a quantidade de reações adversas na medula óssea. Em todos os casos estatisticamente significantes o domínio emocional apresentou correlações positivas e o domínio dor, correlações negativas. A idade apresentou correlação estatisticamente significante e negativa com os domínios físico e dificuldades financeiras e positiva com perda de apetite. Pelo procedimento de comparações múltiplas, as diferenças ocorreram entre os estados civis casado e separado e também casado e solteiro, entre as religiões católica e evangélica, entre os ensinos fundamental e médio e entre médio e superior; para a extensão da doença os domínios dor e insônia apresentaram diferenças estatisticamente significantes entre as categorias de extensão. Para renda mensal, os domínios fisico, desempenho de papel, emocional, constipação e dificuldades financeiras apresentaram diferenças estatisticamente significantes entre as categorias de renda. Nos domínios fisico, desempenho de papel e emocional as diferenças ocorreram entre as faixas de 1 a 3 e mais de 6 salários. Concluiu-se que as reações adversas causadas pelo tratamento antineoplásico com quimioterapia afetaram de algum modo as pacientes, causando déficits em vários domínios, prejudicando assim sua QVRS

Saving for Retirement and Investing for Growth. Report of the CEPS-RCMI Task Force on Long-term Investing and Retirement Savings. CEPS Task Force Report, September 2013

Europe is facing a double challenge: a significant need for long-term investments – crucial levers for economic growth – and a growing pension gap, both of which call for resolute action. Crucially, at a time when low interest rates and revised prudential standards strain the ability of life insurers and pension funds to offer guaranteed returns, Europe lacks a framework ensuring the quality and accessibility of long-term investment solutions for small retail investors and defined contribution pension plans. This report considers the potential to steer household financial wealth – accounting for over 60% of total financial wealth in Europe – towards long-term investing, which would achieve two goals at once: higher growth and higher pensions. It follows a holistic approach that considers both solution design – how to gear product structuring towards long-term investing – and market structure – how to engineer a competitive market setting that is able to deliver high-quality and cost-efficient solutions. The report also considers prudential rules for insurers and pension funds and the potential to build a single market for less-liquid funds, occupational and personal pensions, with improved investor protection. It urges policy-makers to act aggressively to deliver more inclusive, efficient and resilient retail investment markets that are better equipped and more committed to deliver value over the long-term for beneficiaries.

Performance of Long-Term Care Systems in Europe. ENEPRI Research Report No. 117, 21 December 2012

This report evaluates the performance of long-term care (LTC) systems in Europe, with a special emphasis on four countries that were selected in Work Package 1 of the ANCIEN project as representative of different LTC systems: Germany, the Netherlands, Spain and Poland. Based on a performance framework, we use the following four core criteria for the evaluation: the quality of life of LTC users, the quality of care, equity of LTC systems and the total burden of LTC (consisting of the financial burden and the burden of informal caregiving). The quality of life is analysed by studying the experience of LTC users in 13 European countries, using data from the Survey of Health, Ageing and Retirement in Europe (SHARE). Older persons with limitations living at home have the highest probability of receiving help (formal or informal) in Germany and the lowest in Poland. Given that help is available, the sufficiency of the help is best ensured in Switzerland, Italy and the Netherlands. The indirectly observed properties of the LTC system are most favourable in France. An older person who considers all three aspects important might be best off living in Belgium or Switzerland. The horizontal and vertical equity of LTC systems are analysed for the four representative countries. The Dutch system scores highest on overall equity, followed by the German system. The Spanish and Polish systems are both less equitable than the Dutch and German systems. To show how ageing may affect the financial burden of LTC, projections until 2060 are given for LTC expenditures for the four representative countries. Under the base scenario, for all four countries the proportions of GDP spent on public and private LTC are projected to more than double between 2010 and 2060, and even treble in some cases. The projections also highlight the large differences in LTC expenditures between the four countries. The Netherlands spends by far the most on LTC. Furthermore, the report presents information for a number of European countries on quality of care, the burden of informal caregiving and other aspects of performance. The LTC systems for the four representative countries are evaluated using the four core criteria. The Dutch system has the highest scores on all four dimensions except the total burden of care, where it has the second-best score after Poland. The German system has somewhat lower scores than the Dutch on all four dimensions. The relatively large role for informal care lowers the equity of the German system. The Polish system excels in having a low total burden of care, but it scores lowest on quality of care and equity. The Spanish system has few extreme scores. Policy implications are discussed in the last chapter of this report and in the Policy Brief based on this report.

Extending working life in Finland. CEPS Working Document No. 387, 22 November 2013

This report reviews national and private initiatives to allow the elderly to continue their participation in the Finnish labour market and provides an analysis of the labour market and living conditions of seniors. We are interested in how those over 50 can be engaged in various forms of employment and lifelong learning. We find strong evidence that Finland generally provides good institutional conditions for active ageing. The quick and early ageing process was tackled by the fundamental pension reform that already prolonged retirement substantially and will probably facilitate later retirement as the attitudes concerning retirement change. On the other hand, Finland still seems to lag behind the other Nordic welfare states, has considerable problems in providing the same health conditions to low educated people in physically demanding occupations and could - – with respect to family pension in particular – invest further efforts in reforming the pension system. While many of the reforms Finland has conducted seem to be favourable and transferable to other European countries that still face the steepest phases of ageing in their societies, a reluctance towards changing attitudes that we observe in Finland, shows that organizing active ageing is a long-term project.

Life Is Getting Worse in ESS Data: Is This Due to Micro or Macro Factors? Bruges European Economic Research (BEER) Papers 28/November 2013

In order to evaluate the success of a society, measuring well-being might be a fruitful avenue. For a long time, governments have trusted economic measures, Gross Domestic Product (GDP) in particular, to assess their success. However GDP is only a limited measure of economic success, which is not enough to show whether policies implemented by governments have a positive perceived impact on the people they represent. This paper belongs to the studies of the relationship between measures of well-being and economic factors. More precisely, it tries to evaluate the decrease in happiness and life satisfaction that can be observed in European countries in the 2000-2010 decade. It asks whether this deterioration is mainly due to microeconomic factors, such as income and individual characteristics, or rather to environmental (macroeconomics) factors such as unemployment, inflation or income inequality. Such aggregate factors could impact individual happiness per se because they are related to the perception of an aggregate risk of unemployment or income fall. In order to strengthen this interpretation, this paper checks whether the type of social protection regime existing in different countries mediates the impact of macroeconomic volatility on individual well-being. To go further, adopting the classification of welfare regimes proposed by Esping-Andersen (1990), it verifies whether the decreasing pattern of subjective well-being varies across these regimes. This is partly due to the aggregate social protection expenditure. Hence, this paper brings some additional evidence to the idea that macroeconomic uncertainty has a cost in terms of well-being. More protective social regimes are able to reduce this cost. It also proposes an evaluation of the welfare cost of unemployment and inflation (in terms of happiness and life satisfaction), in each of the different social protection regimes. Finally different measures of well-being, i.e. cognitive, hedonic and eudaimonic, are used to confirm the above mentioned result.

Preventing Social Death in Long Term Care: Fostering Social Connectivity in the U.S. and The Netherlands. ACES Working Papers, July 2012

Long term care (LTC) is both costly and of increasing concern as baby boomers age and more people live longer with chronic conditions. Today, people receive formal and informal LTC supports in homes, nursing homes, and alternative settings around the world. Where people live and the way LTC is delivered has an important impact on whether person’s receiving care thrive as they age. This paper is about how different LTC environments in the U.S. and The Netherlands foster or impede social connectivity, suggesting that quality of life will be impeded and types of social death, or disconnection from social life, more often the result in environments that limit choice and self determination, limit access to privacy and social connection, and limit access to reciprocal exchanges, a key component of participating in relationships typical of the concept of “the gift” introduced by anthropologist Marcel Mauss in 1954. Building on ethnographic data from a 15-month study of LTC in The Netherlands and a review of staffing practices in LTC environments in the U.S. and The Netherlands, I will explore concepts of reciprocity and social connectivity impacted by various LTC environments in two countries known to experiment with different models of care. This research builds on social constructivist notions of death and dying explored throughout this edited volume and adds to this effort examination of social death in anthropological perspective.

Markers for silent atrial fibrillation in esophageal long-term electrocardiography.

PURPOSE Paroxysmal atrial fibrillation (PAF) often remains undiagnosed. Long-term surface ECG is used for screening, but has limitations. Esophageal ECG (eECG) allows recording high quality atrial signals, which were used to identify markers for PAF. METHODS In 50 patients (25 patients with PAF; 25 controls) an eECG and surface ECG was recorded simultaneously. Partially A-V blocked atrial runs (PBARs) were quantified, atrial signal duration in eECG was measured. RESULTS eECG revealed 1.8‰ of atrial premature beats in patients with known PAF to be PBARs with a median duration of 853ms (interquartile range (IQR) 813-1836ms) and a median atrial cycle length of 366ms (IQR 282-432ms). Even during a short recording duration of 2.1h (IQR 1.2-17.2h), PBARs occurred in 20% of PAF patients but not in controls (p=0.05). Left atrial signal duration was predictive for PAF (72% sensitivity, 80% specificity). CONCLUSIONS eECG reveals partially blocked atrial runs and prolonged left atrial signal duration - two novel surrogate markers for PAF.

Optimized methods for extracting circulating small RNAs from long-term stored equine samples.

Circulating miRNAs in body fluids, particularly serum, are promising candidates for future routine biomarker profiling in various pathologic conditions in human and veterinary medicine. However, reliable standardized methods for miRNA extraction from equine serum and fresh or archived whole blood are sorely lacking. We systematically compared various miRNA extraction methods from serum and whole blood after short and long-term storage without addition of RNA stabilizing additives prior to freezing. Time of storage at room temperature prior to freezing did not affect miRNA quality in serum. Furthermore, we showed that miRNA of NGS-sufficient quality can be recovered from blood samples after >10 years of storage at -80 °C. This allows retrospective analyses of miRNAs from archived samples.

Is socioeconomic position early in life associated with physical activity during adulthood following the accumulation of risk model with additive effects?

L'activité physique améliore la santé, mais seulement 4.8% des Canadiens atteignent le niveau recommandé. La position socio-économique est un des déterminants de l'activité physique les plus importants. Elle est associée à l’activité physique de manière transversale à l’adolescence et à l’âge adulte. Cette thèse a tenté de déterminer s'il y a une association à long terme entre la position socio-économique au début du parcours de vie et l’activité physique à l’âge adulte. S'il y en avait une, un deuxième objectif était de déterminer quel modèle théorique en épidémiologie des parcours de vie décrivait le mieux sa forme. Cette thèse comprend trois articles: une recension systématique et deux recherches originales. Dans la recension systématique, des recherches ont été faites dans Medline et EMBASE pour trouver les études ayant mesuré la position socio-économique avant l'âge de 18 ans et l'activité physique à ≥18 ans. Dans les deux recherches originales, la modélisation par équations structurelles a été utilisée pour comparer trois modèles alternatifs en épidémiologie des parcours de vie: le modèle d’accumulation de risque avec effets additifs, le modèle d’accumulation de risque avec effet déclenché et le modèle de période critique. Ces modèles ont été comparés dans deux cohortes prospectives représentatives à l'échelle nationale: la 1970 British birth cohort (n=16,571; première recherche) et l’Enquête longitudinale nationale sur les enfants et les jeunes (n=16,903; deuxième recherche). Dans la recension systématique, 10 619 articles ont été passés en revue par deux chercheurs indépendants et 42 ont été retenus. Pour le résultat «activité physique» (tous types et mesures confondus), une association significative avec la position socio-économique durant l’enfance fut trouvée dans 26/42 études (61,9%). Quand seulement l’activité physique durant les loisirs a été considérée, une association significative fut trouvée dans 21/31 études (67,7%). Dans un sous-échantillon de 21 études ayant une méthodologie plus forte, les proportions d’études ayant trouvé une association furent plus hautes : 15/21 (71,4%) pour tous les types et toutes les mesures d’activité physique et 12/15 (80%) pour l’activité physique de loisir seulement. Dans notre première recherche originale sur les données de la British birth cohort, pour la classe sociale, nous avons trouvé que le modèle d’accumulation de risque avec effets additifs s’est ajusté le mieux chez les hommes et les femmes pour l’activité physique de loisir, au travail et durant les transports. Dans notre deuxième recherche originale sur les données canadiennes sur l'activité physique de loisir, nous avons trouvé que chez les hommes, le modèle de période critique s’est ajusté le mieux aux données pour le niveau d’éducation et le revenu, alors que chez les femmes, le modèle d’accumulation de risque avec effets additifs s’est ajusté le mieux pour le revenu, tandis que le niveau d’éducation ne s’est ajusté à aucun des modèles testés. En conclusion, notre recension systématique indique que la position socio-économique au début du parcours de vie est associée à la pratique d'activité physique à l'âge adulte. Les résultats de nos deux recherches originales suggèrent un patron d’associations le mieux représenté par le modèle d’accumulation de risque avec effets additifs.
