Cuidar do corpo para melhor cuidar da casa

Objectivo: O objectivo deste estudo foi avaliar a implementação de um projecto comunitário na sintomatologia neuro-músculo-esquelética de domésticas. Metodologia: Realizou-se um estudo experimental que incluiu 30 domésticas (20 no grupo experimental e 10 no grupo de controlo) aleatoriamente seleccionadas. Foram utilizados como instrumentos de avaliação o Questionário de Avaliação de Risco, a Escala de Borg da Percepção Subjectiva do Esforço e o Questionário Nórdico Músculo-Esquelético. O projecto comunitário englobou uma acção de educação para a saúde e um programa de exercícios específicos. Resultados: A implementação do projecto comunitário diminuiu significativamente (p<0,05) a sintomatologia neuro-músculo-esquelética, a percepção subjectiva de esforço e a intensidade média de dor reportada pelas domésticas durante a realização de várias tarefas. As domésticas melhoraram significativamente (p<0,05) os seus conhecimentos em relação aos factores de risco e modificaram significativamente (p<0,05) os seus comportamentos, adoptando posturas mais adequadas. Conclusões: O serviço doméstico propicia o aparecimento de sintomatologia neuro-músculo-esquelética e, como tal, a implementação de uma acção de educação para a saúde e um programa de exercícios específicos tornam-se eficazes como projecto de promoção de saúde.

Self-perceived health status in older adults: regional and sociodemographic inequalities in Spain

OBJECTIVE: To assess regional and sociodemographic differences in self-perceived health status among older adults. METHODS: A face-to-face quality of life survey was conducted in a representative sample of the Spanish population comprising 1,106 non-institutionalized elderly aged 60 or more in 2008. Logistic regression models were used to explain self-perceived health status according to the EuroQol Group Visual Analogue Scale (EQ-VAS). Independent variables included sociodemographic and health characteristics as well as the nomenclature of territorial units for statistics level 1 (NUTS1: group of autonomous regions) and level 2 (NUTS 2: autonomous regions). RESULTS: Younger and better off respondents were more likely to have a positive self-perceived health status. Having no chronic conditions, independence in performing daily living activities and lower level of depression were also associated with positive self-perceived health status. People living in the south of Spain showed a more negative self-perceived health status than those living in other regions. CONCLUSION: The study results point to health inequality among Spanish older adults of lower socioeconomic condition and living in the south of Spain. The analysis by geographic units allows for international cross-regional comparisons.

On the development of an automatic voice pleasantness classification and intensity estimation system

In the last few years, the number of systems and devices that use voice based interaction has grown significantly. For a continued use of these systems, the interface must be reliable and pleasant in order to provide an optimal user experience. However there are currently very few studies that try to evaluate how pleasant is a voice from a perceptual point of view when the final application is a speech based interface. In this paper we present an objective definition for voice pleasantness based on the composition of a representative feature subset and a new automatic voice pleasantness classification and intensity estimation system. Our study is based on a database composed by European Portuguese female voices but the methodology can be extended to male voices or to other languages. In the objective performance evaluation the system achieved a 9.1% error rate for voice pleasantness classification and a 15.7% error rate for voice pleasantness intensity estimation.

Application of FTA and the perceived impact on employment policies: the case of nanotechnology in the Netherlands, Germany and Portugal

In this paper we will analyse the usage of FTA to support decision-making in employment policy relate to specific occupational groups. The examples can be better understood if one focus on the nanotechnology and its implications on some sectors (clothing, bio-medical engineering, micro-electronics). When this is done will be clear which occupations will engage a restructuring process (engineers, specialised technicians, qualified machine operators, quality controllers) and what policies are being designed to cope with it. This means toward which extend social partners have driven specific policies on these issues (focused in their sectors).

Perceived health in the Portuguese population aged ? 35

OBJECTIVE To evaluate the exploratory relationship between determinants of health, life satisfaction, locus of control, attitudes and behaviors and health related quality of life in an adult population. METHODS Observational study (analytical and cross-sectional) with a quantitative methodological basis. The sample was composed oy 1,214 inhabitants aged ≥ 35 in 31 civil parishes in the County of Coimbra, Portugal, 2011-2012. An anonymous and voluntary health survey was conducted, which collected the following information: demographic, clinical record, health and lifestyle behaviors; health related quality of life (Medical Outcomes Study, Short Form-36); health locus of control; survey of health attitudes and behavior, and quality of life index. Pearson’s Linear Correlation, t-Student, Wilcoxon-Mann-Whitney; One-way ANOVA; Brown-Forsythe’s F; Kruskal-Wallis; Multiple Comparisons: Tukey (HSD), Games-Howell and Conover were used in the statistical analysis. RESULTS Health related quality of life was shown to be lower in females, in older age groups, in obese/overweight individuals, widows, unassisted, those living alone, living in rural/suburban areas, those who did not work and with a medium-low socioeconomic level. Respondents with poor/very poor self-perceived health (p < 0.0001), with chronic disease (p < 0.0001), who consumed < 3 meals per day (p ≤ 0.01), who were sedentary, who slept ≤ 6 h/day and had smoked for several years revealed the worst health results. Health related quality of life was positively related with a bigger internal locus, with better health attitudes and behaviors (physical exercise, health and nutritional care, length of dependence) and with different areas of life satisfaction. CONCLUSIONS Better health related quality of life was associated with certain social, psychological, family and health characteristics, a satisfactory lifestyle, better socioeconomic conditions and a good internal locus of control over health attitudes and behaviors.

Mensagens para a adesão da população pediátrica aos exames de ressonância magnética: aplicação do modelo Perceived Behavioral Change

Segundo o modelo de mudança de comportamento [Perceived Behavioral Change (PBC)], proposto por Thus Ajzen e aplicado pelo Centro de Programas de Comunicação, nos EUA, a adesão das crianças aos exames de ressonância magnética (RM) poderá ser facilitada através da aplicação de estratégias, como o conhecimento prévio do exame pelas crianças, pelos cuidadores ou ambos. Com este estudo pretendeu-se identificar critérios e boas práticas na produção de informação relativa ao exame de RM, dirigida à população pediátrica.

Problemática associada à utilização de diferentes tipos de mochila para transporte de material escolar

O transporte de cargas é uma tarefa comum para crianças, adolescentes e adultos, pela necessidade de transferência diária de objetos pessoais, livros e artigos de papelaria para os locais de trabalho ou escolas. Diversos autores apontam que o peso carregado durante transporte de material é o principal responsável pelo aparecimento de dor lombar. Deste modo é importante o constante estudo da temática para a definição recomendações e limites. O presente estudo teve como principais objetivos a caraterização da problemática associada à utilização de mochilas e a determinação do Peso Máximo Aceitável (PMA) e do Índice de Esforço Percebido (IEP) para a tarefa de transporte de mochilas, através da abordagem psicofísica. O estudo foi desenvolvido com estudantes do 7º, 8º e 9º ano de escolaridade e, foi dividido em duas fases. Na 1ª fase foram aplicados questionários para a análise da problemática associada à utilização de diferentes tipos de mochilas escolares. Nesta fase, foram incluídos aspetos associados à identificação do tipo de mochila mais utilizada, as rotinas e hábitos dos estudantes e as características da mochila utilizada. Verificou-se que os estudantes utilizam, maioritariamente, a mochila de duas alças para transporte de material escolar. Posteriormente foram efetuadas medições de peso da mochila, altura e peso aos 131 estudantes que constituíram a amostra da 1º fase. O principal objetivo deste ponto foi identificar o tipo de mochila habitualmente utilizada pelos estudantes assim como, o peso transportado nas mochilas. Na 2ª fase foi efetuado um estudo para a determinação do PMA e do IEP, através da abordagem psicofísica, para a tarefa de transporte de mochila, considerando-se uma amostra constituída por 10 estudantes. Para este estudo, apenas foi considerada a mochila mais frequentemente utilizada, identificada na 1º fase. A tarefa consistiu no transporte da mochila nos dois ombros e com as alças devidamente ajustadas ao corpo, num percurso pré-definido, de acordo com o procedimento experimental. Os resultados indicaram que nem todos os estudantes transportam mochilas com pesos dentro das recomendações da Organização Mundial de Saúde. O PMA determinado pelos estudantes foi de 6.8 kg para a mochila de duas alças e a região dos ombros foi identificada durante todo o estudo como sendo a que apresentava maior intensidade de dor durante o transporte da mochila.

Ascariasis in the subdistrict of Cavacos, municipality of Alterosa (MG), Brazil: effect of mass treatment with albendazole on the intensity of infection

The clinical and epidemiologic aspects of infection with Ascaris lumbricoides were studied in a random stratified sample of the population of the subdistrict of Cavacos, municipality of Alterosa (Minas Gerais, Brazil). The effect of mass treatment with a single dose of albendazole on the prevalence and intensity of infection was also studied six months later in the same population. During the first phase of the study, a questionnaire was applied to 248 individuals to obtain information about the socioeconomic, sanitary and clinical conditions of the population surveyed. A total of 230 fecal samples were also examined by the Kato-Katz technique in order to determine the intensity of A. lumbricoides infection. Two hundred and two individuals were simultaneously submitted to blood counts and 70 children aged 12 years or less were evaluated for nutritional status. The presence of A. lumbricoides and other helminth eggs was also determined in 22 soil samples collected in the urban zone of Cavacos. Infection with enteroparasitic helminths was detected in 29.1% of the sample, with a predominance of A. lumbricoides (23.9%). Parasitism and/or intensity of A. lumbricoides infection were significantly correlated with age range (15 years or less), social class, sanitary and living conditions (water, sewage and domiciliary area per person), and presence of abdominal pain. However, these parameters were not correlated with nutritional status or hematocrit levels. During the second phase of the study, a slight but not statistically significant decrease in the prevalence of A. lumbricoides infection was detected after treatment with albendazole. However, an important and significant reduction in the amount of A. lumbricoides eggs eliminated through the feces was detected, indicating that the intensity of A. lumbricoides infection was lower in all the age ranges of the Cavacos population, especially among younger individuals, even six months after administration of the anthelminthic agent.

Solar Intensity Forecasting using Artificial Neural Networks and Support Vector Machines

This paper presents several forecasting methodologies based on the application of Artificial Neural Networks (ANN) and Support Vector Machines (SVM), directed to the prediction of the solar radiance intensity. The methodologies differ from each other by using different information in the training of the methods, i.e, different environmental complementary fields such as the wind speed, temperature, and humidity. Additionally, different ways of considering the data series information have been considered. Sensitivity testing has been performed on all methodologies in order to achieve the best parameterizations for the proposed approaches. Results show that the SVM approach using the exponential Radial Basis Function (eRBF) is capable of achieving the best forecasting results, and in half execution time of the ANN based approaches.

Impact of compliance with different guidelines on physical activity during pregnancy and perceived barriers to leisure physical activity

The aims of the this prospective study were to analyze physical activity (PA) engagement during the first and second trimesters, considering the different guidelines published on PA, to document the individual characteristics associated with the accomplishment of these guidelines and to examine pregnant women’s perceived barriers to leisure PA, using a socioecological framework. A sample of 133 pregnant women in two stages – at 10–12 weeks’ gestation (T1) and 20– 22 weeks’ gestation (T2) – were evaluated. PA was assessed by accelerometry during the T1 and T2 evaluation stages. Socio-demographic characteristics, lifestyle factors and barriers to leisure PA were assessed via questionnaire. A large proportion of women (ranging from 32% to 96%) did not reach the levels of PA recommended by the guidelines. There were no significant differences between T1 and T2 with regard to compliance with PA recommendations. A decrease in PA levels from T1 to T2 was noted for all recommendations. No associations were found between participants’ characteristics and adherence to the recommendations in T1 and T2. No significant differences were found in barriers to leisure PA between T1 and T2. The most commonly reported barriers to leisure PA were intrapersonal, not health related. Our results indicate that there were no differences between trimesters regarding compliance of PA recommendations, and perceived barriers were similar in both trimesters.

Give some to get some - Analysing the relationship between worker satisfaction with human resources management and perceived individual performance in a Portuguese hospital

The purpose of this study is to investigate the association between the satisfaction with HRM practices in an organization and the workers' perceived performance. We are interested in learning if indeed workers that are more satisfied with the organization’s practices will also perceive themselves as more hardworking than others, thus confirming the happy-productive worker hypothesis, from an individual perception standpoint. Data originates from a large Portuguese hospital, with a sample of 952 clinical and nonclinical hospital workers. Data was originally explored using SPSS software and later tested in AMOS software where a multiple regression model was constructed and tested. Results indicate that overall satisfaction with HRM practices are related with the workers’ perceived performance; most of the HRM satisfaction subscales also relate, except for pay and performance appraisal, that do not seem to be good predictors of the workers perceived performance. The present study is based on a single large public hospital, and thus, these findings need to be further tested in other settings. This study offers some clues regarding the areas of HRM that seem to be more related with the workers’ perceived performance, and hence provide an interesting framework for managers dealing with healthcare teams. This study contributes to the happy-productive worker hypothesis research, by including seldom used variables in the equation and taking a different perspective. Results provide new clues for investigation and practice regarding the areas of action in HRM that seem to be more prone to elicit perceived effort from the workers.

Dor crónica lombar : incapacidade auto-reportada em trabalhadores das IPSS de Arronches e sua relação com factores psicossociais e intensidade da dor

RESUMO: Vários estudos realizados sugerem que os factores psicossociais (nível de satisfação laboral; nível educacional; a catastrofização da dor e crenças de medoevitamento)têm um importante papel como factores associados ao desenvolvimento de cronicidade da DL (Krismer & van Tulder, 2007; Kwon et al., 2006; Leclerc et al., 2009; Pincus, Santos, Breen, Burton e Underwood., 2008.) Objectivo: Analisar a associação entre as variáveis catastrofização da dor, crenças de medo-evitamento da dor e intensidade da dor com a incapacidade funcional auto-reportada, numa amostra de indivíduos com DCL. Metodologia: A população alvo foi constituída por 160 funcionários da Santa Casa da Misericórdia e Centro de Bem Estar Social de Arronches. Integraram a amostra 133 funcionários que se disponibilizaram a responder aos diferentes instrumentos de avaliação utilizados (“Roland–Morris Disability Questionnaire”(RMQ); “ Questionário de Caracterização e Levantamento de Factores de Risco e Impacto associado à DCL”; “Pain Catastrophing Scale” (PCS) e o “Fear- Avoidance Beliefs Questionnaire” (FABQ). A recolha de dados realizou-se entre Agosto e Novembro de 2010. Resultados: Neste estudo, verificou-se que 39,1 % dos indivíduos referiam DCL não específica. Relativamente à incapacidade funcional autoreportada, obteve-se um score médio 5,87 no RMQ. Obteve-se um valor de rs=0,425,p<0,01, para a associação entre a catastrofização da dor e incapacidade. Relativamente à associação entre crenças de medo-evitamento, sub-escala actividade física e incapacidade, foi obtido o valor de rs= 0,074 e para a associação entre as crenças de medo-evitamento, sub-escala trabalho e incapacidade, verificou-se rs=0,422, p<0,01. No que respeita à associação entre percepção da intensidade dor actual e a incapacidade, obteve-se um valor rs= 0,177 e a associação entre a dor percepcionada em 2009 e incapacidade, aferiu um resultado de rs=0,291, p<0,05. Conclusão: Concluímos que existe uma associação moderada entre catastrofização da dor e a incapacidade funcional auto-reportada, e também entre crenças de medo-evitamento relativamente ao trabalho e a incapacidade funcional auto-reportada. Relativamente à associação entre a dor percepcionada em 2009 e a incapacidade funcional auto-reportada a associação é baixa. Não sendo encontrada associação entre crenças de medo-evitamento relativamente à actividade física e a incapacidade funcional auto-reportada, nem para a associação entre percepção da intensidade da dor actual e a incapacidade. Esta pesquisa contribuiu assim, para dar a conhecer factores relevantes avaliar em indivíduos com DCL, podendo a sua modificação contribuir para a prevenir maiores níveis de incapacidade funcional ou melhorar a efectividade do tratamento utilizado. --------------------ABSTRACT: Several studies suggest that psychosocial factors (level of job satisfaction, education level, and the pain catastrophizing and fear-avoidance beliefs) have an important role as factors associated with development of chronicity LBP (Krisma & van Tulder, 2007 ; Kwon et al., 2006, Leclerc et al. 2009; Pincus, Santos, Breen, Burton and Underwood., 2008.) Objective: To assess the association between the variables of pain catastrophizing, fear-avoidance beliefs, pain, intensity pain and self-reported functional disability in a sample of people with chronic LBP. Methodology: The study consisted of 160 employees of the Santa Casa da Misericórdia and Centro de Bem Estar Social of Arronches. Integrated sample of 133 employees who agreed to respond to different assessment tools used (Roland-Morris Disability Questionnaire (RMQ), "Questionnaire Survey of Characterization and Risk Factors and Impact associated with the DCL," "Pain Catastrophing Scale(PCS) and "Fear-Avoidance Beliefs Questionnaire (FABQ). Data collection took place between August and November 2010. Results: In this study, it was found that 39.1% of subjects reported no specific chronic LBP. For the self-reported functional disability, we obtained a medium score of 5.87 on the RMQ. We obtained a value of rs = 0.425, p <0.01, for the association between catastrophizing in pain and disability. Regarding the association between fear-avoidance beliefs, sub-scale physical activity and disability, was obtained a value of rs = 0.074 and for the association between fear-avoidance beliefs, sub-scale work and disability, there was rs = 0.422, p <0.01. Regarding the association between perceived pain intensity and pain disability present we obtained a value rs = 0.177 association between pain and perceived disability in 2009 and measured an outcome of rs = 0.291, p <0.05.Conclusion: That there is a moderate association between catastrophizing and pain self-reported functional disability, and also between fear-avoidance beliefs in relation to employment and self-reported functional disability. Regarding the association between pain and perceived disability in 2009 self-reported the association is low. Not being an association between earavoidance beliefs for physical activity and self-reported functional disability, or for the association between perception of current pain intensity and disability. This research contributed so, to disclose relevant factors evaluate in individuals with chronic LBP, its modification may help to prevent higher levels of functional disability or improve the effectiveness of treatment used.

Leptospirosis severity may be associated with the intensity of humoral immune response

Leptospirosis severity may be increasing, with pulmonary involvement becoming more frequent. Does this increase result from an intense immune response to leptospire? Notice that renal failure, thrombocytopenia and pulmonary complications are found during the immune phase. Thirty-five hospitalized patients with Weil's disease had 5 blood samples drawn, from the 15th day to the 12th month of symptoms, for ELISA-IgM, -IgG and -IgA specific antibody detection. According their 1st IgG titer, the patients were divided into: group 1 (n = 13) titer > 1:400 (positive) and group 2 (n = 22) titer <=1:400 (negative). Early IgG antibodies in group 1 showed high avidity which may indicate reinfection. Group 1 was older, had worse pulmonary and renal function, and fever for a longer period than group 2. Throughout the study, IgG and IgA titers remained higher in group 1. In conclusion, the severity of Weil's disease may be associated with the intensity of the humoral immune response to leptospire.

Portal cd4+ and cd8+ t lymphocyte correlate to intensity of interface hepatitis in chronic hepatitis C

BACKGROUND: The pathogenesis of chronic hepatitis C is still a matter of debate. CD4+ and CD8+ T lymphocytes (TL) are typically observed within the portal and periportal spaces of affected livers, but their functional role in hepatitis C progression has not been fully elucidated. METHODS: CD4+ and CD8+ TL were quantified by immunohistochemistry in portal and periportal spaces of 39 liver biopsies from patients with chronic hepatitis C. They were associated to demographic data, histological parameters, laboratory findings of patients and hepatitis C genotypes. RESULTS: There was high numbers of CD4+ and CD8+ TL from which the density of CD4+ T was higher than CD8+ TL in portal and periportal spaces. CD4+ and CD8+ TL were directly correlated to intensity of interface hepatitis. CD8+ TL correlated to serum enzyme levels. CONCLUSION: The high numbers of CD4+ and CD8+ TL in portal and periportal spaces and their correlation to interface hepatitis suggest that hepatitis C evolution depends on the action of intrahepatic T lymphocytes, lending support to the notion of an immune-mediated mechanism in the pathogenesis of chronic hepatitis C.
