Culpa y bienestar en cuidadores familiares de personas mayores dependientes institucionalizadas

Introduction and objectiveThe experience of family caregivers after nursing home admission has received much less attention, probably because many caregivers experience an initial sense of initial emotional relief. However, for some caregivers nursing home admission is a stressor despite the reduced physical burden of caregiving. Caregiver distress following institutionalization has been related to the new burdens and challenges encountered in the nursing home. Ambivalence and guilt related to the institutionalization decision have been identified as sources of stress. Therefore, this study examined the effect of guilt and well-being on the perceived stress of family caregivers of institutionalized dependent persons.Materials and methodsTwo hundred and one family caregivers of institutionalized persons in a nursing home (La Rioja, Spain) participated. Perceived stress, caregiving guilt and subjective well-being, sociodemographic and caregiving-related variables were assessed. Linear regression analyses and correlations between variables were performed.ResultsGuilt and five dimensions of well-being (anxiety, vitality, self-control and depression, except general health) significantly predicted stress (R²adj = .552 (F (6, 198) = 41.71, P<.001)). The effect size was large (95% CI = .461).ConclusionsPaying attention to family caregivers’ feelings of guilt during institutionalization is important. This will enable the design and implementation of psychosocial interventions that improve caregiver adjustment immediately after institutionalization.     

Population and prehistory III: Food-dependent demography in variable environments

The population dynamics of preindustrial societies depend intimately on their surroundings, and food is a primary means through which environment influences population size and individual well-being. Food production requires labor; thus, dependence of survival and fertility on food involves dependence of a population’s future on its current state. We use a perturbation approach to analyze the effects of random environmental variation on this nonlinear, age-structured system. We show that in expanding populations, direct environmental effects dominate induced population fluctuations, so environmental variability has little effect on mean hunger levels, although it does decrease population growth. The growth rate determines the time until population is limited by space. This limitation introduces a tradeoff between population density and well-being, so population effects become more important than the direct effects of the environment: environmental fluctuation increases mortality, releasing density dependence and raising average well-being for survivors. We discuss the social implications of these findings for the long-term fate of populations as they transition from expansion into limitation, given that conditions leading to high well-being during growth depress well-being during limitation.     

Boar culling and mortality in commercial swine breeding herds

The objectives of this study were to measure culling rate and mortality rate of boars; to compare boar life day (BLD: days from birth date to removal date), boar herd life day (BHLD: days from herd entry date to removal date) and herd entry age of boars between high-performing herds and ordinary herds (herd groups); to examine herd measurements for BLD, BHLD and boar age at herd entry; and to observe removal patterns and survival curves for boars by herd groups. This study used 2474 records of individual boars born in 108 herds from 2000 to 2003. Two herd groups were formed on the basis of the upper 25th percentile of pigs weaned per mated female per year (2001-2005). Mixed-effects models and survival analysis were performed. Means of BLD and BHLD (±S.E.M.) were 984 ± 9.5 and 781 ± 8.4 d, respectively. Annualized culling rate and mortality rate were 0.411 and 0.035 boars per 365 BHLD, respectively. Boars in high-performing herds had 51 higher BLD and 62 higher BHLD than those in ordinary herds (P < 0.01). High-performing herds had 32 d lower entry ages than ordinary herds (P < 0.01). Herd measurements such as herd mortality and herd size were not associated with both BLD and BHLD. The hazards in survival analysis were associated with herd groups (P < 0.05). Measurements in the present study provide benchmarks for boar removal in commercial herds.     

A taurine and caffeine-containing drink stimulates cognitive performance and well-being

Summary. Caffeine- and taurine-containing drinks have been on the European market for about a decade, and research on the individual constituents of these drinks indicates an improvement in cognitive performance resulting from consumption of such drinks. In this double-blind, placebo-controlled study using 10 graduate students, we obtained the P300 components of event-related potential (ERP) waveforms following an auditory oddball paradigm, measured motor reaction time, and applied the d2 test for the assessment of attention. Status of mood was assessed by the “Basler-Befindlichkeitsbogen” questionnaire, a standard test for evaluation of feelings of well-being. Measurements were made at night, prior to and starting one hour after consumption of energy drink ingredients or placebo. At the end of the experiment (midnight), P300 latency and motor reaction time were significantly longer compared with baseline measurements in the placebo group, but were unchanged in the energy drink group. In the test system for evaluating feelings of well-being, total scores, vitality scores and social extrovertedness scores were significantly decreased in the placebo group but not in the energy drink group. The findings clearly indicate that the mixture of three key ingredients of Red Bull^R Energy Drink used in the study (caffeine, taurine, glucuronolactone) have positive effects upon human mental performance and mood. These effects may be mediated by the action of caffeine on purinergic (adenosinergic) receptors and taurine modulation of receptors. As half of the study cohort were non-caffeine users, the described effects cannot be explained in terms of the restoration of plasma caffeine levels to normal following caffeine withdrawal.

A new class of composite indicators for measuring well-being at the local level: An application to the Equitable and Sustainable Well-being (BES) of the Italian Provinces

The aim of this paper is to propose a class of composite indicators for measuring well-being at the local level, which takes into account the variability between and within the local units.Although we believe that well-being is a multidimensional concept and cannot be reduced to a single measure, we also stress the importance of aggregating the information of several well-being indicators into a reduced number of composite indicators, one for each well-being domain, which play a crucial role in policymaking and benchmarking.As an application, we focus on the Equitable andSustainable Well-being of the Italian Provinces. In particular, based on a dataset containing 41 elementary indicators, we aggregate them by domain, comparing different aggregative approaches and illustrating the difference in the rankings of the Italian Provinces they produce. Finally, as an illustrative example, we focus on a member of the class of composite indicators that accounts both for vertical variability (between the Provinces) and horizontal variability (within the Provinces). The construction of a composite index for each domain allows us to evaluate and compare multidimensional well-being among the Italian Provinces.     

Comparison of Subjective Well-Being and Personality Assessments in the Clouded Leopard (Neofelis nebulosa), Snow Leopard (Panthera uncia), and African Lion (Panthera leo)

The study of subjective well-being in nonhuman animals is growing in the field of psychology, but there are still only a few published studies and the focus is on primates. To consider whether the construct of subjective well-being could be found in another mammal, this study aimed to assess subjective well-being in felids and to examine its association with personality. Personality is one of the strongest and most consistent predictors of well-being in humans. This relationship could have important implications for other species, because personality has also been shown to affect health outcomes including stress, morbidity, and mortality. As in previous studies in nonhuman animals, the study results revealed that subjective well-being was related to agreeableness/openness and neuroticism in clouded leopards, neuroticism in snow leopards, and impulsiveness and neuroticism in African lions. The implications of these results for health outcomes and the welfare of animals in captivity are discussed. More research on any direct links among personality, subjective well-being, and these outcomes is important to advancing this field and adding another tool for improving captive animals' lives.     

The great transformation: A long-run perspective on physical well-being in Canada

During the 19th century the physical stature of the Canadian-born stagnated or declined slightly in spite of a substantial increase in income. Stature varied regionally within Canada. The Quebec population was especially short; men in the Atlantic coastal region were taller than their low incomes would lead us to expect. Heights increased dramatically in the 20th Century. The pattern of long-run change is consistent with evidence of age-specific mortality and with the relationship between income and physical well-being envisaged by Preston [Preston, S., 1975. The changing relationship between mortality and the level of economic development. Popul. Stud. 29, 231-248]. The transition from stagnant or declining stature to secular increase points to a dramatic shift ca. 1900 in the evolution of the physical standard of living in Canada.     

Review: Assessment of dairy cow welfare at pasture: measures available,gaps to address,and pathways to development of ad-hoc protocols

Pasture is generally perceived as positive for dairy cow welfare, but it nevertheless exposes cows to heat, parasites, and other challenges. This review is intended for people ready to design comprehensive protocols for assessing the welfare of dairy cows at pasture. We provide an overview of the benefits and risks of pasture for cows, and then go on to identify the available and feasible measures for assessing cow welfare at pasture and the gaps that need to be addressed to develop specific welfare measures. Some of the measures from on-farm welfare assessment protocols designed for indoor use (e.g. Welfare Quality®) are relevant for cows at pasture (e.g. lameness scoring). However, the timing, location and/or method for certain measures (e.g. observation of social behaviour) need to be adapted to the pasture context, as cows at pasture can roam over a large area. Measures to address specific pasture-related risks (e.g. heat stress, biosecurity) or benefits (e.g. expression of a wide range of behaviours) should be implemented in order to capture all dimensions of cow welfare at pasture. Furthermore, cow welfare is liable to vary over the grazing season due to changes in weather conditions, grass quality and pasture plots that induce variations in lying surface conditions, food availability, distance to walk to the milking parlour, and so on. It is therefore important to investigate the variability in different welfare measures across the pasture season to check whether they hold stable over time and, if not, to determine solutions that can give an overview across the grazing season. Sensors offer a promising complement to animal and environment observations, as they can capture long-term animal monitoring data, which is simply not possible for a one-day welfare-check visit. We conclude that some measures validated for indoor situations can already be used in pasture-based systems, while others need to be validated for their fitness for purpose and/or use in pasture conditions. Furthermore, thresholds should probably be determined for measures to fit with pasture contexts. If all measures can be made adaptable to all situations encountered on farms or variants of the measures can at least be proposed for each criterion, then it should be possible to produce a comprehensive welfare assessment protocol suitable for large-scale use in near future.     

“Föhn illness” and human biometeorology in the Chinook area of Canada

Literature on the nature and possible causes of föhn illness is reviewed. Seven physiological and psychological aspects of human well-being were solicited from 1828 residents of southern Alberta by telephone interview. Data were evaluated to determine if well-being was weather related. Meteorological parameters included eight 48-h weather types, temperature, humidity, wind and pressure. The expected increase in föhn illness symptoms during the frequent warm chinook and decrease at times of cold non-chinook weather were not present. However, with the cool chinook (temperature slightly below freezing) many people claimed additional irritability and, to a lesser extent, more pain in their joints, headaches and nervousness. Several adverse symptoms were positively correlated with wind velocity. However, no widespread chinook illness comparable to the föhn illness was found.     

Desarrollo y validación de un instrumento observacional para la evaluación del bienestar en personas con demencia desde la perspectiva de la atención centrada en la persona: Listado de Indicadores de Bienestar

IntroductionWithin the context of Person Centred Care, the present paper shows the creation and validation process of an observational tool for the assessment of the wellbeing of people with dementia, from a perspective that seeks to highlight the effects that the physical and social environment have on the person, and how these are reflected in the well-being.MethodsThe List of Wellbeing Indicators (LIBE) was created following an inductive iterative process with professionals from different disciplines, until the validated version was reached. It was then validated in two successive studies with a sample of 79 people with dementia. Discrimination capacity of the scale indicators, internal consistency, inter-rater reliability, and convergent and divergent validity were determined.ResultsAn internal consistency of Cronbach́s alpha 0.81 was obtained. The inter-rater reliability, analysing intraclass correlation coefficient (ICC) within the 3 raters, was significant for all the indicators in the tool, with scores between 0.59-1.00. Convergent validity was studied comparing scores in each LIBE indicator with scores in each QUALID indicator, and some significant associations were found between response categories in both tools. For the discriminant validity, the scores obtained in each LIBE indicator were compared with the scores in each PAINAD-Sp item, and no significant associations were found.ConclusionLIBE offers an observational measure of behaviours that can be considered well-being indicators in people with dementia living in residential care. LIBE is a valid and reliable tool that offers a different perspective of measuring a construct that has been infrequently explored in dementia population. Is also an easy to apply tool, with different uses (clinical, intervention, research), and applicable for professionals of several disciplines.
