Is Formal Social Participation Associated with Cognitive Function in Middle-Aged and Older Adults? A Systematic Review with Meta-Analysis of Longitudinal Studies.

This systematic review with meta-analysis aimed to explore the association between formal social participation and cognitive function in middle-aged and older adults using data from longitudinal studies. A comprehensive search was conducted in Scopus, PubMed, and Web of Science for longitudinal studies that assessed the association between formal social participation and cognitive function in middle-aged and older adults published between January 2010 to 19 August 2022. Risk of bias was judged using the RoBANS tool. Meta-analysis using a random-effects model was computed with odds ratio (OR) and 95% confidence interval (CI) for cognitive decline probability. Sensitivity analyses were made to explore any changes to the pooled statistical heterogeneity and pooled effect size. Certainty of evidence was judged using the GRADE framework. We included 15 studies comprising 136,397 participants from 5 countries. Meta-analyses showed that formal social participation was associated with reduced cognitive decline (OR = 0.78, 95% CI 0.75-0.82, p < 0.001), with very low certainty of evidence. Formal social participation appears to enhance cognition in middle-aged and older adults, but further high-quality research is needed given the very low certainty of evidence.

Association between formal social participation and cognitive function in middle-aged and older adults: a longitudinal study using SHARE data.

Formal social participation significantly impacts health and well-being, potentially mitigating cognitive decline, although not consistently across all studies. Existing research often focuses solely on baseline participation levels, and age-related differences have primarily been explored among the Asian population. Therefore, this longitudinal study aims to assess the association between formal social participation and cognition across different age groups in individuals aged 50+ living in Europe and Israel, while capturing the dynamic nature of formal social participation. We use data from three waves (four, six, and eight) of the Survey of Health, Ageing, and Retirement in Europe (SHARE), comprising 85,601 respondents. Linear mixed-effects models were applied. The results show that participation in formal social activities mitigates cognitive decline in middle-aged and older adults, especially among those aged 70 to 79 and 80+. These findings support the need for social policies promoting formal social activities, for lasting cognitive health benefits.

ESBL-Positive Enterobacteriaceae from Dogs of Santiago and Boa Vista Islands, Cape Verde: A Public Health Concern.

Antimicrobial resistance is a public health threat with an increasing expression in low- and middle-income countries such as Cape Verde. In this country, there is an overpopulation of dogs, which may facilitate the spread of resistant bacteria, including extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae. To clarify the role of dogs as reservoirs for the dissemination of this bacterial group, 100 rectal swab samples were collected from confined (n = 50) and non-confined (n = 50) dogs in Santiago and Boa Vista Islands, Cape Verde. These were analyzed using conventional bacteriological techniques for the detection of ESBL-producing Enterobacteriaceae and characterization of their pathogenic and resistance profiles. Twenty-nine samples displayed ESBL-positive bacteria, from which 48 ESBL-producing isolates were obtained and mostly identified as Escherichia coli. Multiple antimicrobial resistance indexes ranged from 0.18 to 0.70 and half of the isolates were classified as multidrug-resistant. Isolates were capable of producing relevant virulence factors, including biofilm, showing virulence indexes between 0.29 and 0.71. As such, dogs in Cape Verde may act as reservoirs of resistant bacteria, including pathogenic and zoonotic species, representing a public health concern. Although further investigation is needed, this study proposes the periodical analysis of dogs' fecal samples to monitor resistance dissemination in the country, in a One-Health perspective.

In Vivo Effect of a Nisin-Biogel on the Antimicrobial and Virulence Signatures of Canine Oral Enterococci.

Periodontal disease is a relevant oral disease in dogs and nisin-biogel has been previously proposed to be used in its control. Enterococci, as inhabitants of the oral cavity with a high genetic versatility, are a reliable bacterial model for antimicrobial studies. Our goal was to evaluate the in vivo influence of the long-term dental application of the nisin-biogel on the virulence and antimicrobial signatures of canine oral enterococci. Twenty dogs were randomly allocated to one of two groups (treatment group-TG with nisin-biogel dental application, or control group-CG without treatment) and submitted to dental plaque sampling at day 0 and after 90 days (T90). Samples were processed for Enterococcus spp. isolation, quantification, identification, molecular typing and antimicrobial and virulence characterization. From a total of 140 enterococci, molecular typing allowed us to obtain 70 representative isolates, mostly identified as E. faecalis and E. faecium. No significant differences (p > 0.05) were observed in the virulence index of the isolates obtained from samples collected from the TG and CG at T90. At T90, a statistically significant difference (p = 0.0008) was observed in the antimicrobial resistance index between the isolates from the TC and CG. Oral enterococci were revealed to be reservoirs of high resistant and virulent phenotypes.

The Longitudinal Association between Co-Residential Care Provision and Healthcare Use among the Portuguese Population Aged 50 and Over: A SHARE Study.

Co-residential care is associated with poor caregiver health and a high burden. Although Portugal relies heavily on co-residential care by individuals aged 50 and over, studies on the impact of co-residential care provision on Portuguese caregivers' healthcare use are lacking. This study aims to analyze the impact of co-residential care (spousal and non-spousal care) on healthcare use of the Portuguese population aged 50 plus. Data from waves 4 (n = 1697) and 6 (n = 1460) of the Survey of Health, Ageing and Retirement in Europe (SHARE) were used. Negative Binomial Generalized Linear Mixed Models with random (individual level) and fixed (covariates) effects were performed. The results show that the number of visits to the doctor decrease significantly over time for the co-residential spousal caregivers as compared to the non-co-residential caregivers. This result highlights the fact that the Portuguese co-residential spousal caregiver group is at a higher risk of not using healthcare, thus jeopardizing their own health and continuity of care. Promoting more accessible healthcare services and implementing public policies adjusted to the needs of informal caregivers are important to improve the health and healthcare use of Portuguese spousal co-residential caregivers.

The importance of social participation for life satisfaction among spouse caregivers aged 65 and over.

Spouse caregivers report lower levels of life satisfaction. However, social participation generates life satisfaction. The main goal of this study is to analyse the contribution of social participation to the life satisfaction of European and Israeli spouse caregivers aged 65 plus. The study uses cross-sectional data from 17 European countries, plus Israel, which are part of wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE). The sample was limited to individuals aged 65+, who were classified as non-caregivers (N = 25,313) or spouse caregivers (N = 1977). The mean scores of life satisfaction by country and caregiver status were calculated and tests for a two-group comparison and multilevel logistic regressions were performed. The spouse caregiver group reported lower levels of satisfaction with life. Tests for a two-group comparison show that the group of spouse caregivers reports fewer social activities than the non-caregivers group. Moreover, multilevel linear regressions allowed us to conclude that providing spousal care at older ages (65+) is related to lower life satisfaction but that providing spousal care and reporting having social participation is related to higher life satisfaction than in the group of spouse caregivers who are not involved in social activities, and non-caregivers. Social participation is a key issue in the life satisfaction of spouse caregivers aged 65 years and older. The social participation of spouse caregivers should be a concern to relatives, communities, social and health professionals, as well as public policymakers.

The Contribution of the Internet to Reducing Social Isolation in Individuals Aged 50 Years and Older: Quantitative Study of Data From the Survey of Health, Ageing and Retirement in Europe.

BACKGROUND: Social isolation has a negative impact on the quality of life of older people; therefore, studies have focused on identifying its sociodemographic, economic, and health determinants. In view of the growing importance of the internet as a means of communication, it is essential to assess whether internet use interferes with social isolation. OBJECTIVE: This study specifically aims to clarify the relationship between internet use and social isolation of individuals aged ≥50 years, for which other surveys present contradictory results. METHODS: We performed logistic regression analysis with social isolation as the dependent variable, internet use as the interest variable, and several other sociodemographic, economic, and health characteristics of the individuals as control variables. The sample size was 67,173 individuals aged 50 years and older from 17 European countries (Portugal, Greece, Italy, Spain, Denmark, Sweden, Austria, Belgium, France, Germany, Switzerland, Luxemburg, Poland, Czech Republic, Slovenia, Estonia, and Croatia) plus Israel, who were interviewed in the Survey of Health, Ageing and Retirement in Europe (SHARE), wave 6. RESULTS: The results show that countries differ in the level of social isolation and rate of internet use by individuals aged 50 years and older. They also evidence that in most of the countries analyzed, social isolation of internet users was lower compared to that of nonusers after controlling for a set of sociodemographic, economic, and health characteristics of the individuals that have been previously described in the literature as determinants of social isolation. Indeed, on average, although 31.4% of individuals in the nonuser group experienced high social isolation, only 12.9% of individuals who used the internet experienced this condition. CONCLUSIONS: Internet users show lower social isolation. This result underlines the importance of promoting e-inclusion in Europe as a way to counter social isolation of individuals aged 50 years and older.

Precautionary behaviours of individuals with multimorbidity during the COVID-19 pandemic.

Studies show that older individuals with multimorbidity are more susceptible to develop a more severe case of COVID-19 when infected by the virus. These individuals are more likely to be admitted to Intensive Care Units and to die from COVID-19-related conditions than younger individuals or those without multimorbidity. This research aimed to assess whether there are differences in terms of precautionary behaviours between individuals aged 50 + with multimorbidity and their counterparts without multimorbidity residing in 25 European countries plus Israel. We used data from the SHARE-COVID19 questionnaire on the socio-demographic and economic characteristics, multimorbidity, and precautionary behaviours of individuals. SHARE wave 8 and 7 databases were also used to fully identify individuals with multimorbidity. Our results showed that individuals with multimorbidity were more likely to exhibit precautionary behaviours than their counterparts without multimorbidity when gender, age, education, financial distress and countries were included as controls. Additionally, we found that women, more educated individuals and those experiencing more financial distress adopt more protective behaviours than their counterparts. Our results also indicate that the prevalence of precautionary behaviours is higher in Spain and Italy and lower in Denmark, Finland and Sweden. To guarantee the adoption of preventive actions against COVID-19, public health messaging and actions must continue to be disseminated among middle and older aged persons with multimorbidity, and more awareness campaigns should be targeted at men and less educated individuals but also at persons experiencing less financial distress, particularly in countries where people engaged in fewer precautionary behaviours.

Home confinement and mental health problems during the Covid-19 pandemic among the population aged 50 and older: A gender perspective.

Home confinement during the Covid-19 pandemic is usually associated with worsening mental health. In the case of older adults, although they have been identified as a vulnerable group in terms of mental health, the results of studies on the relationship between home confinement and mental health are not consistent and few studies have adopted a gender perspective. Using data from the SHARE Corona Survey (2020), we aimed to analyse the role of gender on the relationship between home confinement and increased depression in individuals aged 50 and over living in Europe and Israel. Our study shows that, although women reported increased depression/sadness during the Covid-19 pandemic more often than men, it was the latter who experienced the greatest increase.

Determination of 14 trace elements in blood, serum and urine after environmental disaster in the Doce River basin: Relationship between mining waste and metal concentration in the population.

BACKGROUND: Exposure to chemical substances after an environmental disaster can cause both toxic effects and changes in the health status of people who live in or have proximity to environments of this nature, so that the concern with populations is growing. METHODS: In this cross-sectional study, blood, serum and urine samples were collected from 100 volunteers from Santo Antônio do Rio Doce, eight from Ilha das Pimentas and 50 from the control group; and analyzed by inductively coupled plasma mass spectrometry for biomonitoring of Al, As, Ba, Cd, Co, Cu, Cr, Fe, Hg, Mn, Ni, Se, Pb, Zn. In addition, a comprehensive questionnaire was applied to collect demographic and socioeconomic information, as well as lifestyle. RESULTS: The concentrations of As, Al, Cd, Ni and Mn were above the reference value in some biological matrices, with more pronounced exposure in Ilha das Pimentas. The concentrations of As, Cd, Cu, Co, Pb and Zn showed statistical differences regarding gender in the different biological matrices. The trace elements in the blood, serum and urine showed significant correlations when considering age and habits such as the consumption of cigarettes, alcoholic beverages and fish. The main correlations were observed between Co, Cr, Mn, Ni and Pb in the blood and cigarette consumption. CONCLUSION: This is the first study in these regions after the environmental disaster and confirmation of the diagnosis and health care of the participants should be promoted for clinical investigation and the eventual need for treatment. Human biomonitoring demonstrated high concentrations of some toxic elements, with more accentuated exposure in Ilha das Pimentas.

A Study of the Association between the Stringency of Covid-19 Government Measures and Depression in Older Adults across Europe and Israel.

Background: The COVID-19 pandemic is having major adverse consequences for the mental health of individuals worldwide. Alongside the direct impact of the virus on individuals, government responses to tackling its spread, such as quarantine, lockdown, and physical distancing measures, have been found to have a profound impact on mental health. This is manifested in an increased prevalence of anxiety, depression, and sleep disturbances. As older adults are more vulnerable and severely affected by the pandemic, they may be at increased psychological risk when seeking to protect themselves from COVID-19. Methods: Our study aims to quantify the association between the stringency of measures and increased feelings of sadness/depression in a sample of 31,819 Europeans and Israelis aged 65 and above. We hypothesize that more stringent measures make it more likely that individuals will report increased feelings of sadness or depression. Conclusions: We found that more stringent measures across countries in Europe and Israel affect the mental health of older individuals. The prevalence of increased feelings of sadness/depression was higher in Southern European countries, where the measures were more stringent. We therefore recommend paying particular attention to the possible effects of pandemic control measures on the mental health of older people.

Spousal Care and Pain Among the Population Aged 65 Years and Older: A European Analysis.

Background: Spousal care is the most important source of informal care in old age. Nevertheless, despite the growing importance of this issue, the association between providing spousal care inside the household and pain remains unexplored in Europe. Objective and Methods: This study aims to estimate the prevalence of pain reported by spouse caregivers aged 65 plus that provide care inside the household and to investigate the association between providing spousal care and pain. Data from 17 European countries that participated in wave 6 of the Survey of Health, Aging and Retirement in Europe (SHARE) is used. The analyses are based on 26,301 respondents aged 65 years and older who provide informal care inside the household to their spouse/partner exclusively (N = 1,895) or do not provide any informal care (inside or outside the household) (24,406). Descriptive statistics and multilevel logistic regressions (individual-level as level 1, and country as level 2) were performed. Results: Overall, spouse caregivers report pain more often (63.4%) than their non-caregiver's counterparts (50.3%). Important differences in the prevalence of pain among spouse caregivers were found between countries, with Portugal (80.3%), Spain (74.6%), France (73%), Italy (72.4%), and Slovenia (72.1) showing the highest prevalence of pain, and Denmark (36%), Switzerland (41.5) and Sweden (42.3%), the lowest. Results from multilevel logistic regressions show that European individuals aged 65+ who provide spousal care have an increased likelihood of reporting pain (OR 1.30; CI = 1.13-1.48). Conclusion: Our results suggest that in Europe, spouse caregivers aged 65+ are at greater risk of experiencing pain. Therefore, European policymakers should consider spouse caregivers as a health priority group, and take measures to ensure they receive comprehensive health and socio-economic support.

Social isolation, physical inactivity and inadequate diet among European middle-aged and older adults.

BACKGROUND: Social isolation is a growing public health concern for older adults, as it has been associated with poor health and premature mortality. On the other hand, physical inactivity and an inadequate diet are important health risk behaviours associated with physical and mental health problems. Considering that there is no research examining the possible relationship between social isolation and the above mentioned health risk behaviours of European middle-aged and older adults, this cross-sectional study aims to contribute to filling this gap. METHODS: We used data from the SHARE project (Survey of Health, Ageing and Retirement in Europe), wave 6 (2015), release 7.0.0 (N = 67,173 individuals from 17 European countries plus Israel). Statistical tests for a two-group comparison were carried out to assess the differences between highly socially isolated individuals and low/intermediate socially isolated ones. Logistic regressions by country were performed to examine whether social isolation is associated with physical inactivity and an inadequate diet in the population aged 50 + . RESULTS: Our results point out that, for the majority of the countries analysed, highly socially isolated individuals are more likely than low/intermediate isolated ones to be physically inactive and to consume less fruit or vegetables on a daily basis. In 9 European countries (Austria, Germany, Sweden, Denmark, Greece, Belgium, Poland, Luxembourg and Estonia) highly socially isolated individuals are more likely to be physically inactive. On the other hand, in 14 European countries (Austria, Germany, Sweden, Italy, France, Denmark, Greece, Switzerland, Belgium, Czech Republic, Luxembourg, Slovenia, Estonia and Croatia), high social isolation increases the likelihood of having an inadequate diet. CONCLUSION: Highly socially isolated European middle-aged and older adults are more prone to be physically inactive and to have an inadequate diet in terms of daily consumption of fruit and vegetables. The reduced social integration, social support and companionship of the highly socially isolated individuals may explain this association. Our results reinforce the importance of social and health policies targeting highly socially isolated European individuals aged 50 + .

[The Impact of COVID-19 in Older People in Portugal: Results from the Survey of Health, Ageing and Retirement (SHARE)]. / O Impacto da COVID-19 na População Idosa em Portugal: Resultados do Survey of Health, Ageing and Retirement (SHARE).

INTRODUCTION: In March 2020, the World Health Organization declared COVID-19 as a pandemic, and Portugal reported its initial cases. In this study, we aimed to determine the impact of COVID-19 on Portuguese individuals aged over 60 years old. MATERIAL AND METHODS: We performed a cross-sectional study using data from the Survey of Health, Ageing and Retirement in Europe (SHARE 8: COVID-19 Survey). We selected a sample of 1080 noninstitutional Portuguese individuals aged ≥ 60 years. RESULTS: The study sample consisted of 605 (56%) women and 475 (44%) men, with a mean age of 70 ± 9.1 years. In total, 80% of the participants experienced higher levels of anxiety, 73% felt more depressed and 30% experienced additional sleep problems comparedto the period before the pandemic. Interestingly, there were no statistically significant differences between the sexes or the two selected age groups (60 - 74 and over 75 years old) regarding the incidence of these changes. Only 23%, of those that were interviewed maintained their walking routines. In addition, only 8% of the participants continued visiting family members as frequently as before. While 8% of the participants were refused some form of medical treatment, 56% claimed that they experienced healthcare delays. However,only 15% of the participants reported that their health status worsened during the pandemic. DISCUSSION: The pandemic has had a significant impact on Portuguese individuals aged ≥ 60 years; which is in agreement with the findings of previous international studies. It changed the participants' routines and increased their anxiety and depression levels. Despite the deterioration of healthcare services, most participants did not experience worsening of their health status. CONCLUSION: In conclusion, a COVID-19 pandemic had a significant impact on the elderly population, particularly regarding their mental health.

Introdução: Em março de 2020, a COVID-19 foi declarada pandemia pela Organização Mundial da Saúde e Portugal registou os seus primeiros casos. Este estudo visou determinar o impacto da COVID-19 na população portuguesa maior de 60 anos. Material e Métodos: Trata-se de um estudo observacional transversal que analisa várias variáveis de saúde, comportamentais, sociais e económicas. Utilizaram-se dados do projecto Survey of Health, Ageing and Retirement (SHARE 8: COVID-19 Survey), seleccionando uma amostra de 1080 portugueses não institucionalizados e maiores de 60 anos. Resultados: A amostra englobou 605 mulheres (56%) e 475 homens (44%), com idade média de 70 ± 9,1 anos. No total, 80% dos participantes notou aumento da ansiedade, 73% sentiu-se mais deprimido e 30% considerou que o seu sono piorou em relação ao período anterior à pandemia. Não houve diferenças estatisticamente significativas entre os sexos ou as duas faixas etárias analisadas (60 - 74 e ≥ 75 anos) quanto à incidência destas alterações. No respeitante a saídas de casa, apenas 23% dos entrevistados manteve os hábitos de passeio e 8% manteve as visitas a familiares no seu padrão habitual. Relativamente ao acesso a cuidados médicos, a 8% foi negado algum tratamento e 56% queixou-se do adiamento dos cuidados. Apenas 13% referiu um agravamento do seu estado de saúde durante a pandemia. Discussão: Este trabalho mostra que esta pandemia impactou a população portuguesa com mais de 60 anos, o que está em linha com o reportado noutros estudos internacionais. Os hábitos alteraram-se, e a ansiedade e depressão aumentaram. Apesar da deterioração dos cuidados de saúde, a maioria dos participantes não notou agravamento do seu estado de saúde. Conclusão: Em conclusão, a pandemia por COVID-19 teve um impacto significativo na população idosa particularmente no que concerne à sua saúde mental.

Health impact of providing informal care in Portugal.

BACKGROUND: Middle-aged and older adults play an important role in the provision of informal support, however, the impact on the health of those individuals who provide informal care is unclear. The main objectives of this study are: (1) to assess the prevalence of co-residential caregiving provided by individuals aged 50+; (2) to analyze differences between the group of Portuguese co-residential caregivers and the group of Portuguese non-caregivers; (3) to examine the longitudinal effect of providing informal care on the health of co-residential informal caregivers in Portugal. METHODS: Data from wave 4 and wave 6 of the Survey of Health Ageing and Retirement in Europe (SHARE) were used. A linear mixed model and a generalized mixed model were used to analyze the longitudinal effect of providing informal care on the health (physical health and depressive symptoms) of Portuguese individuals aged 50 + . RESULTS: In both SHARE waves analyzed, Portugal had the highest percentage of co-residential caregivers aged 50+. At baseline, the Portuguese co-residential caregiver population, compared to non-caregivers, has a lower percentage of employed individuals (14.9% compared to 25.7%) and a higher percentage of individuals with four or more depressive symptoms (56.4% compared to 35.5%). The caregivers also have a lower quality of life (CASP-12) (30.93 compared to 32.59). Marginal differences in educational levels between the caregiver and non-caregiver groups were also found, with co-residential caregivers having lower levels of education (72.3% have ISCED 0-2 compared to 64.7%), lower levels of cognitive function (- 2.321 compared to - 1.784), lower levels of physical health (- 0.180 compared to - 0.076) and lower engagement in moderate or vigorous physical activity (14.9% compared to 21.5%). Longitudinal models reveal that providing care within the household is not associated with physical health (b = 0.048; se = 0.035; p = 0.167), but is associated with depressive symptoms (OR = 1.609; 95% CI = 1.141-2.271; p = < 0.010). CONCLUSIONS: Portugal has the highest percentage of co-residential caregivers aged 50+. In that country, providing informal care to a household member is associated with depressive symptoms. Portuguese policymakers should therefore promote programs to prevent and alleviate the depressive symptoms experienced by individuals aged 50+, who provide co-residential care.

Do European co-residential caregivers aged 50+ have an increased risk of frailty?

One important health challenge associated with ageing is frailty, which has been acknowledged as a new public health priority. However, only a few studies have explored the relationship between providing care at older ages and frailty. The main objective of this study is to assess whether there is an association between providing co-residential care and frailty, according to gender and from a European cross-sectional perspective, among the population aged 50+. Data from 17 European countries that participated in wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE) is used (N = 52,073). Multinomial logistic regressions were used to estimate caregivers' chances of frailty. The results show that the prevalence of pre-frailty and frailty differs according to the caregiver's status, gender and the European region. The highest prevalence of pre-frailty was found in the group of female caregivers from Northern countries (57.3%), and the highest prevalence of frailty was found in the group of female caregivers from Southern countries (29.3%). Providing co-residential care is positively associated with the risk of being pre-frail in women, in all European regions (Northern: OR 1.724, 95% CI 1.190-2.496; Central: OR 1.213, 95% CI 1.010-1.456; Eastern: OR 1.227, 95% CI 1.031-1.460; Southern: OR 1.343, 95% CI 1.103-1.634), and with being frail for both genders in the Southern region (female: OR 1.527, 95% CI 1.060-2.200; male: OR 1.644, 95% CI 1.250-2.164). The results of this study suggest that female co-residential caregivers are a greater risk of being pre-frail in all European regions except Southern Europe, where male and female co-residential caregivers are a greater risk of being frail, compared with non-caregivers. European policy makers should create political measures to prevent and reverse frailty among European co-residential caregivers.

Confidant Network and Quality of Life of Individuals Aged 50+: The Positive Role of Internet Use.

Studies on the quality of life (QoL) of older adults have tended to focus on sociodemographic, economic, and health characteristics and, more recently, have analyzed the importance of confidant networks. The Internet has redesigned individuals' daily lives and has become one of the main means of communication. In addition to the aforementioned variables, research must also gauge the importance of this technology and how it can influence the relationship between confidant networks and QoL of older adults. This article aims to analyze the contribution of the Internet on the QoL of older adults as well as the manner that it affects the aforementioned relationship. The present study focuses on a sample of 1,906 individuals aged 50+ who are resident in Portugal and were surveyed in the context of the SHARE project (Survey of Health, Ageing and Retirement in Europe), wave 4. The results of the regression analyses reveal the importance of the Internet on the QoL of older adults. The data also underline the moderating role played by the Internet on the relationship between the confidant network and the QoL of individuals aged 50+, in particular the fact that this technology optimizes the positive impact of confidant networks on QoL. The results obtained thus reinforce the importance of policies aimed at the e-inclusion of older adults as a way to promote their QoL.

Investigando a incidência de solidão em um grupo de idosos portugueses / Investigating the incidence of loneliness in a group of Portuguese older persons / Investigando la incidencia de la soledad en un grupo de portugueses de la tercera edad

Na esteira da alteração dos padrões demográficos, a velhice marca de modo sem precedentes a sociedade contemporânea. Ser idoso tem sido largamente descrito na literatura como uma experiência de solidão, sentimento de caráter multifacetado que se origina na insatisfação com as relações interpessoais. Este trabalho foca a associação entre tal estado psíquico e o envelhecimento, e mensura a incidência deste sentimento em uma amostra composta por 64 idosos que participaram do projeto Bem Envelhecer, da Rede Europeia Anti-Pobreza (EAPN/Portugal). Privilegia-se neste estudo a relação entre as variadas dimensões da solidão e o cruzamento da mesma com diversas variáveis. Para tanto, fora aplicado um inquérito com questões sociodemográficas e a escala SELSA-S (Short Version of the Social and Emotional Loneliness Scale for Adults). Os resultados apontam para a preponderância entre os participantes da pesquisa dos vínculos familiares, em detrimento dos sociais e românticos, e o período etário de 60 a 70 anos como particularmente vulnerável à emergência da solidão.

In the wake of changes to demographic patterns, old age affects contemporary society in an unprecedented manner. Being an elder has been broadly described in the literature as a solitary experience, a multifaceted feeling that is determined by dissatisfaction with interpersonal relationships. This study seeks to evaluate the scale of the different dimensions of this phenomenon (family, social, romantic) in the group of elders who participated in the project Successful Aging of the European Antipoverty Network - Portugal. We intend to further study the association between the sociodemographic characteristics of the target-population and the diverse dimensions of loneliness. To this end, a questionnaire containing socio-demographic questions and the SELSA-S scale (Short Version of the Social and Emotional Loneliness Scale for Adults) was applied on a group of 64 older persons. The results indicate a greater vulnerability of the 'younger' older persons to loneliness and the preponderance of the family dimension of loneliness when compared with the social and romantic dimensions of this phenomenon.

Como consecuencia de cambios en los patrones demográficos, la vejez marca de modo sin precedentes la sociedad contemporánea. El ser anciano ha sido ampliamente descrito en la literatura como una experiencia de soledad, sentimiento de carácter multifacético que se origina en la insatisfacción con las relaciones interpersonales. Este trabajo enfoca la asociación entre tal estado psíquico y el envejecimiento, midiendo la incidencia de este sentimiento en una muestra compuesta por 64 portugueses de la tercera edad. Se privilegia en este estudio la relación entre las variadas dimensiones de la soledad y el cruce de la misma con diversas variables. Para ello, se aplicó una encuesta con cuestiones sociodemográficas y la escala SELSA-S (Short Version of the Social and Emotional Loneliness Scale for Adults). Los resultados apuntan a la preponderancia entre los participantes de la investigación a los vínculos familiares, en detrimento de los sociales y románticos, y el período de edad de 60 a 70 años como particularmente vulnerable a la emergencia de la soledad.

E-inclusion: Beyond individual socio-demographic characteristics.

The changing demographic structure of the population, resulting in unparalleled growth of the elderly population, means that e-inclusion of this population group is considered to be a social and political priority in the context of the Information Society. Most research studies have only considered individual variables -such as age, gender, education, income and health- in the explanatory models of e-inclusion of senior citizens, while ignoring macro variables, such as the welfare systems and public policies in each country. Simultaneously, most studies focus on small-scale samples, lack international comparisons and do not consider the combined effect of several variables that influence Internet use. This study aims to analyse possible differences between two countries that have different welfare systems and public policies, after controlling for the effects of the individual variables that have been identified in the literature as relevant for Internet use. The study focuses on a sample of 8639 individuals, aged 50 years and over, residing in Portugal and Estonia, who participated in the SHARE project (Survey of Health, Ageing and Retirement in Europe). The results of the logistic regression analysis demonstrate that welfare systems and public policies have an impact on the likelihood of Internet use, thus reinforcing the importance of developing public policies to foster e-inclusion of senior citizens.

Eficácia da ivermectina comprimido no tratamento da sarna sarcóptica em cães naturalmente infestados / Efficacy of the ivermectin tablet for treatment of sarcoptic mange in naturally infested dogs

O objetivo deste trabalho foi avaliar a eficácia da ivermectina comprimido administrada por via oral no tratamento de Sarcoptes scabiei em cães naturalmente infestados. Foram selecionados 14 cães com raspados cutâneos positivos para o ácaro S. scabiei, idade de 1-5 anos, sem raça definida, distribuídos na mesma proporção de ambos os sexos, em dois grupos experimentais, compondo 7 animais por grupo. Todos os animais foram tratados a cada 7 dias, totalizando quatro tratamentos em cada cão (Dias 0,7,14 e 21). No grupo I foi administrada a ivermectina5 comprimido na dosagem de 0,2mg/kg e no grupo controle positivo (Grupo II) foi administrado um produto comercial a base de ivermectina comprimido na mesma dosagem do grupo I. Raspados cutâneos, avaliações clinicas e laboratoriais complementares dos cães foram realizadas durante o período de estudo. Clinicamente, não houve diferença significativa entre as avaliações antes e após o tratamento entre os dois grupos. Raspados negativos foram observados em ambos os grupos a partir do dia D+14, mantendo-se negativos até o final do período experimental. As lesões dermatológicas iniciais observadas no acompanhamento clínico regrediram e a partir do dia D+14 a melhora clínica era evidente em ambos os grupos. A ivermectina (Ivermectan Pet, UCBVET Saúde Animal) administrada por via oral foi eficaz no tratamento de S. scabiei em cães naturalmente infestados.(AU)

The aim of this study was to evaluate the efficacy of the ivermectin tablet administered orally for treatment of Sarcoptes scabiei in naturally infested dogs. Fourteen 1 to 5 year-old Mongrel dogs presenting positive skin scrapings for S. scabiei mites, distributed into two groups with equal proportions of both sexes, containing seven animals per group were used in this study. All dogs were treated every 7 days, totaling four treatments in each dog (days 0, +7, +14 and +21). Group I was administered the ivermectin5 tablet at a dose of 0.2mg/kg and positive control group II as given an ivermectin commercial product at the same dose of group I. Skin scrapings, clinical and laboratorial parameters analysis were performed during the experimental period. Clinically there were no significant differences between the two groups evaluated prior and after treatments. Negative skin scrapings were observed in both groups from day +14, remaining negative until the end of the experimental period. The initial skin lesions observed in clinical evaluation regressed from day +14, and clinical improvement was evident in both groups. The ivermectin tablet (Ivermectan Pet, UCBVET Saúde Animal) administered orally was effective to treat S. scabiei infection in naturally infested dogs.(AU)
