Persönliche Bilanzierung der Herausforderungen einer Verwitwung im Zeit- und Geschlechtervergleich

Bisherige Forschung hat die Verwitwung entweder primär als soziales oder als individuelles Ereignis untersucht, selten jedoch wurden beide Perspektiven verbunden. Zudem ist wenig darüber bekannt, inwiefern bisherige Forschungsergebnisse Perioden- oder Kohorteneffekte wiederspiegeln. In diesem Beitrag wird die persönliche Bilanzierung nach der Verwitwung älterer Schweizer Frauen und Männer im Geschlechterund Zeitvergleich untersucht1. Die Datenbasis beruht auf Befragungen von 1.197 verwitweten Frauen und Männern (Alter: 65-102 Jahre), welche 1979, 1994 und 2011 durchgeführt wurden. Während sich die wirtschaftlichen und sozialen Rahmenbedingungen nach einer Verwitwung – namentlich bei Frauen – im Zeitvergleich verbessert haben, zeigen sich bezüglich psychischer Herausforderungen einer Verwitwung keine periodenspezifischen Veränderungen. Psychisch bleibt der Partnerverlust auch bei günstigen Sozialbedingungen ein kritisches Lebensereignis, das individualisiert bewältigt werden muss.

Verwitwung im Alter damals und heute: Die subjektiv Empfundenen Folgen im Zeitvergleich

Während die Verwitwungsforschung negative körperliche, psychische und soziale Folgen auf Individualebene vielseitig aufzuzeigen vermochte, wurde kaum untersucht, inwiefern diese individuellen Auswirkungen einer Verwitwung im Alter von Kohortenzugehörigkeit und historischem Kontext mitdeterminiert sind. Vor dem Hintergrund, dass sich sowohl Geschlechtsrollenverständnis, Familienstrukturen, aber auch das Gesundheits-­ und Sozialsystem in unserem Lande stark verändert haben, ist davon auszugehen, dass Verwitwete unterschiedlicher Kohorten sich hinsichtlich Ressourcen und Belastungen unterscheiden. Der vorliegende Beitrag untersucht mit Hilfe von Daten des IP13 des Nationalen Forschungsschwerpunkts LIVES (‚Democratisation of old Age’), inwiefern die subjektiv empfundenen psychophysischen, sozialen und finanziellen Folgen der Verwitwung zwischen zwei Kohorten variieren. Dazu werden Daten zweier Kohorten von verwitweten Personen aus den Kantonen Genf und Wallis im Alter von 65 Jahren und älter verglichen. Die eine Befragung fand 1979 statt (455 Verwitwete), die andere 2011 (298 Verwitwete). Die Ergebnisse zeigen, dass sich in den berichteten Schwierigkeiten nach einer Verwitwung eine Verbesserung der ökonomischen und sozialen Situation in der Schweiz in den vergangenen dreissig Jahren widerspiegelt, insbesondere für Frauen. Im Gegensatz dazu zeigen sich bei den psychischen Auswirkungen keine bedeutenden periodenspezifischen Veränderungen. Es spricht somit vieles dafür, dass der Verlust des Partners/der Partnerin psychisch auch bei günstigen sozialen Rahmenbedingungen ein kritisches Lebensereignis darstellt, das nach wie vor individuell zu bewältigen ist.

The development of self-esteem

In this article, we review new insights gained from recent longitudinal studies examining the development of self-esteem and its influence on important life outcomes. The evidence supports the following three conclusions. First, self-esteem increases from adolescence to middle adulthood, peaks at about age 50 to 60 years, and then decreases at an accelerating pace into old age; moreover, there are no cohort differences in the self-esteem trajectory from adolescence to old age. Second, self-esteem is a relatively stable, but by no means immutable, trait; individuals with relatively high (or low) self-esteem at one stage of life are likely to have relatively high (or low) self-esteem decades later. Third, high self-esteem prospectively predicts success and well-being in life domains such as relationships, work, and health. Given the increasing evidence that self-esteem has important real-world consequences, the topic of self-esteem development is of considerable societal significance.

Safety profile of prasugrel and clopidogrel in patients with acute coronary syndromes in Switzerland.

OBJECTIVE To assess safety up to 1 year of follow-up associated with prasugrel and clopidogrel use in a prospective cohort of patients with acute coronary syndromes (ACS). METHODS Between 2009 and 2012, 2286 patients invasively managed for ACS were enrolled in the multicentre Swiss ACS Bleeding Cohort, among whom 2148 patients received either prasugrel or clopidogrel according to current guidelines. Patients with ST-elevation myocardial infarction (STEMI) preferentially received prasugrel, while those with non-STEMI, a history of stroke or transient ischaemic attack, age ≥75 years, or weight <60 kg received clopidogrel or reduced dose of prasugrel to comply with the prasugrel label. RESULTS After adjustment using propensity scores, the primary end point of clinically relevant bleeding events (defined as the composite of Bleeding Academic Research Consortium, BARC, type 3, 4 or 5 bleeding) at 1 year, occurred at a similar rate in both patient groups (prasugrel/clopidogrel: 3.8%/5.5%). Stratified analyses in subgroups including patients with STEMI yielded a similar safety profile. After adjusting for baseline variables, no relevant differences in major adverse cardiovascular and cerebrovascular events were observed at 1 year (prasugrel/clopidogrel: cardiac death 2.6%/4.2%, myocardial infarction 2.7%/3.8%, revascularisation 5.9%/6.7%, stroke 1.0%/1.6%). Of note, this study was not designed to compare efficacy between prasugrel and clopidogrel. CONCLUSIONS In this large prospective ACS cohort, patients treated with prasugrel according to current guidelines (ie, in patients without cerebrovascular disease, old age or underweight) had a similar safety profile compared with patients treated with clopidogrel. CLINICAL TRIAL REGISTRATION NUMBER SPUM-ACS: NCT01000701; COMFORTABLE AMI: NCT00962416.

Self-esteem development across the life span: A longitudinal study with a large sample from Germany

The authors examined the development of self-esteem across the life span. Data came from a German longitudinal study with 3 assessments across 4 years of a sample of 2,509 individuals ages 14 to 89 years. The self-esteem measure used showed strong measurement invariance across assessments and birth cohorts. Latent growth curve analyses indicated that self-esteem follows a quadratic trajectory across the life span, increasing during adolescence, young adulthood, and middle adulthood, reaching a peak at age 60 years, and then declining in old age. No cohort effects on average levels of self-esteem or on the shape of the trajectory were found. Moreover, the trajectory did not differ across gender, level of education, or for individuals who had lived continuously in West versus East Germany (i.e., the 2 parts of Germany that had been separate states from 1949 to 1990). However, the results suggested that employment status, household income, and satisfaction in the domains of work, relationships, and health contribute to a more positive life span trajectory of self-esteem. The findings have significant implications, because they call attention to developmental stages in which individuals may be vulnerable because of low self-esteem (such as adolescence and old age) and to factors that predict successful versus problematic developmental trajectories.

Life-span development of self-esteem and its effects on important life outcomes

We examined the life-span development of self-esteem and tested whether self-esteem influences the development of important life outcomes, including relationship satisfaction, job satisfaction, occupational status, salary, positive and negative affect, depression, and physical health. Data came from the Longitudinal Study of Generations. Analyses were based on 5 assessments across a 12-year period of a sample of 1,824 individuals ages 16 to 97 years. First, growth curve analyses indicated that self-esteem increases from adolescence to middle adulthood, reaches a peak at about age 50 years, and then decreases in old age. Second, cross-lagged regression analyses indicated that self-esteem is best modeled as a cause rather than a consequence of life outcomes. Third, growth curve analyses, with self-esteem as a time-varying covariate, suggested that self-esteem has medium-sized effects on life-span trajectories of affect and depression, small to medium-sized effects on trajectories of relationship and job satisfaction, a very small effect on the trajectory of health, and no effect on the trajectory of occupational status. These findings replicated across 4 generations of participants— children, parents, grandparents, and their great-grandparents. Together, the results suggest that self-esteem has a significant prospective impact on real-world life experiences and that high and low self-esteem are not mere epiphenomena of success and failure in important life domains.

Tracking the trajectory of shame, guilt, and pride across the life span

The authors examined age differences in shame, guilt, and 2 forms of pride (authentic and hubristic) from age 13 years to age 89 years, using cross-sectional data from 2,611 individuals. Shame decreased from adolescence into middle adulthood, reaching a nadir around age 50 years, and then increased in old age. Guilt increased from adolescence into old age, reaching a plateau at about age 70 years. Authentic pride increased from adolescence into old age, whereas hubristic pride decreased from adolescence into middle adulthood, reaching a minimum around age 65 years, and then increased in old age. On average, women reported experiencing more shame and guilt; Blacks reported experiencing less shame and Asians more hubristic pride than other ethnicities. Across the life span, shame and hubristic pride tended to be negatively related to psychological well-being, and shame-free guilt and authentic pride showed positive relations with well-being. Overall, the findings support the maturity principle of personality development and suggest that as people age they become more prone to experiencing psychologically adaptive self-conscious emotions, such as guilt and authentic pride, and less prone to experiencing psychologically maladaptive ones, such as shame and hubristic pride.

There is a place for radical cystectomy and urinary diversion, including orthotopic bladder substitution, in patients aged 75 and older: Results of a retrospective observational analysis from a high-volume center

INTRODUCTION The incidence of cancer increases with age and owing to the changing demographics we are increasingly confronted with treating bladder cancer in old patients. We report our results in patients>75 years of age who underwent open radical cystectomy (RC) and urinary diversion. MATERIAL AND METHODS From January 2000 to March 2013, a consecutive series of 224 old patients with complete follow-up who underwent RC and urinary diversion (ileal orthotopic bladder substitute [OBS], ileal conduit [IC], and ureterocutaneostomy [UCST]) were included in this retrospective single-center study. End points were the 90-day complication rates (Clavien-Dindo classification), 90-day mortality rates, overall and cancer-specific survival rates, and continence rates (OBS). RESULTS Median age was 79.2 years (range: 75.1-91.6); 35 of the 224 patients (17%) received an OBS, 178 of the 224 patients (78%) an IC, and 11 of the 224 patients (5%) an UCST. The 90-day complication rate was 54.3% in the OBS (major: Clavien grade 3-5: 22.9%, minor: Clavien Grade 1-2: 31.4%), 56.7% in the IC (major: 27%, minor: 29.8%), and 63.6% in the UCST group (major: 36.4%, minor: 27.3%); P = 0.001. The 90-day mortality was 0% in the OBS group, 13% in the IC group, and 10% in the UCST group (P = 0.077). The Glasgow prognostic score was an independent predictor of all survival parameters assessed, including 90-day mortality. Median follow-up was 22 months. Overall and cancer-specific survivals were 90 and 98, 47 and 91, and 11 and 12 months for OBS, IC, and UCST, respectively. In OBS patients, daytime continence was considered as dry in 66% and humid in 20% of patients. Nighttime continence was dry in 46% and humid 26% of patients. CONCLUSION With careful patient selection, oncological and functional outcome after RC can be good in old patients. Old age as the sole criterion should not preclude the indication for RC or the option of OBS. In old patients undergoing OBS, satisfactory continence results can be achieved.

β2-microglobulin is a systemic pro-aging factor that impairs cognitive function and neurogenesis

Aging drives cognitive and regenerative impairments in the adult brain, increasing susceptibility to neurodegenerative disorders in healthy individuals. Experiments using heterochronic parabiosis, in which the circulatory systems of young and old animals are joined, indicate that circulating pro-aging factors in old blood drive aging phenotypes in the brain. Here we identify β2-microglobulin (B2M), a component of major histocompatibility complex class 1 (MHC I) molecules, as a circulating factor that negatively regulates cognitive and regenerative function in the adult hippocampus in an age-dependent manner. B2M is elevated in the blood of aging humans and mice, and it is increased within the hippocampus of aged mice and young heterochronic parabionts. Exogenous B2M injected systemically, or locally in the hippocampus, impairs hippocampal-dependent cognitive function and neurogenesis in young mice. The negative effects of B2M and heterochronic parabiosis are, in part, mitigated in the hippocampus of young transporter associated with antigen processing 1 (Tap1)-deficient mice with reduced cell surface expression of MHC I. The absence of endogenous B2M expression abrogates age-related cognitive decline and enhances neurogenesis in aged mice. Our data indicate that systemic B2M accumulation in aging blood promotes age-related cognitive dysfunction and impairs neurogenesis, in part via MHC I, suggesting that B2M may be targeted therapeutically in old age.

Is Menopause Optimal?

Various theories have been put forward to explain the fact that humans experience menopause while virtually no animals do. This paper aims to investigate one such theory: children provide a savings technology into old age, but as human babies are usually large and have long gestation periods, a substantial risk of death exists for the mother as she bears children. It seems therefore appropriate to impose a stopping rule for fertility. Given an objective (support for old age) and demographics (mortality of mother and children), an optimal age for menopause can be calculated. Using demographic data from populations that have seen little influence from modern medicine, this optimal age is compared to empirical evidence.

The construction of aging and health in older African American women

Persistence of racial and ethnic health disparities and governmental policies based on outdated ideas of aging call for inclusive approaches to the study of elder African Americans. The lived experiences of aging among urban, poor African American women, who comprise a vulnerable population, are not well known, as most studies focus on mainstream populations. Gerontological studies have tended to employ methods that collapse contextual information for ease of analysis, thus failing to capture nuanced information critically relevant to health of marginalized groups. Few researchers have been successful highlighting the importance of local knowledge, resilience, and resources for health by using participatory methods with older Black women. This study utilizes participatory principles to gather discursive data from nine older African American women, engaged in three generational cohorts: those born around World War II, women born after the great depression, and those born before the great depression. Videotaped and transcribed conversations of cohorts were analyzed in search of contextual factors that influence their experience of aging and health. As women responded to general themes that provoked their talk about their lives, they helped answer the study's questions: How do older African American women make sense of their aging experience? What are some of the important social and cultural influences that shape the construction of aging and health by these women? Are generational discourse groups an effective tool for exploring changes in the experiences of aging? A key finding demonstrated rich heterogeneity of experiences with strong generational influences on the construction of aging and health. The participants' moral orders comprised of traditional values of family, reinforced by personal experiences and the church, have guided their lives through oppression and stress but appear to be failing younger women who have greater exposure to new environmental pressures. Limited time and the size of the study were weaknesses although the women's interest in the study and their participation were gratifying. The participants served to highlight the importance of recognizing generational and other contextual factors in formation of ideas of aging and likelihood of additional challenges to the experience of old age among older, poorer, African Americans. ^

Salinity of the Eocene Arctic Ocean from oxygen isotope analysis of fish bone carbonate

Stable isotope analysis was performed on the structural carbonate of fish bone apatite from early and early middle Eocene samples (~55 to ~45 Ma) recently recovered from the Lomonosov Ridge by Integrated Ocean Drilling Program Expedition 302 (the Arctic Coring Expedition). The d18O values of the Eocene samples ranged from -6.84 per mil to -2.96 per mil Vienna Peedee belemnite, with a mean value of -4.89 per mil, compared to 2.77 per mil for a Miocene sample in the overlying section. An average salinity of 21 to 25 per mil was calculated for the Eocene Arctic, compared to 35 per mil for the Miocene, with lower salinities during the Paleocene Eocene thermal maximum, the Azolla event at ~48.7 Ma, and a third previously unidentified event at ~47.6 Ma. At the Azolla event, where the organic carbon content of the sediment reaches a maximum, a positive d13C excursion was observed, indicating unusually high productivity in the surface waters.

(Table 1) Summary of general lithology in IODP Exp302 cores

The Cenozoic ice-rafted debris (IRD) history of the central Arctic is reconstructed utilizing the terrigenous coarse sand fraction in IODP 302 cores from 0 to 273 meters composite depth. This Holocene - middle Eocene quantitative record of terrigenous sand accumulation on the Lomonosov Ridge, along with qualitative information on grain texture and composition, confirms the interpretation that ice initiation (sea ice and glacial ice) occurred ~46 Ma in the Arctic, and provides a long-term pattern of Arctic ice expansion and decay since the middle Eocene. IRD mass accumulation rates range from 0 to 0.13 g/cm2/ka in the middle Eocene and from 0 to 0.36 g/cm2/ka in the Neogene. IRD mass accumulation rate (MAR) maxima in the Miocene and Pliocene cooccur with either glacial initiation or intensification in the sub-Arctic. The 46.25 Ma IRD onset in the central Arctic slightly precedes the earliest evidence of ice in the Antarctic, and compares in timing with a >1000 ppm decrease in atmospheric concentrations of CO2. The decline of pCO2 in the middle Eocene may have driven both poles across the temperature threshold that enabled the nucleation of glaciers on land and partial freezing of the surface Arctic Ocean, especially during times of low insolation.
