Introduction: Hypoestrogenism is the main characteristic of female aging. It promotes significant changes in body composition, both in fat mass as in lean body mass, leading to a decrease in muscle strength and physical performance. Objective: The aim of this study was to test whether menopausal status and hormone levels are associated with muscular strength and physical performance in middle-aged women. Methods: In a cross-sectional study it was collected sociodemographic data, gynecological history, anthropometric and biochemical measures in women aged 40 to 65 years in Parnamirim-RN. The menopause status (pre, peri and post menopause) was determined by menstrual history. All women underwent three dimensions of physical performance assessment: handgrip dynamometry, gait speed and chair stands test - Short Physical Performance Battery (SPPB). Categorical data were presented as absolute and relative frequencies. Quantitative data were showed as mean and standard deviation and the normality of distribution was verified with Kolmogorov-Smirnov (KS) test. Biochemical measures of estradiol and follicle-stimulating hormone (FSH) were transformed to log10. ANOVA with Tukey post-test for comparison of variables between the groups pre, peri and post-menopausal was performed and then multiple linear regression analyzes. Results: Two hundred and seventy eight women aged 50.2 (±5.58) years composed this study, being 50 women in premenopausal status (18%), 122 in perimenopausal (43.9%), and 106 postmenopausal stage (38.1%). The groups were different in age (p=0.001), marital relationship duration (p <0.001), number of pregnancies (p=0.001) and parity (p=0.001). Differences in biochemical measures were observed among the groups: estradiol (p<0.001), FSH (p<0.001), total cholesterol (p=0.001). There were no differences in gait velocity between menopausal status. Values in mean of grip strength decreased by postmenopausal women to perimenopausal and premenopausal ones (24.5 ± 5.1, 25.6 ± 5.4, 26.9 ± 4.9 for post-stage, pre and peri menopausas, respectively, p = 0.02) and the performance of chair stands test was better in premenopausal women compared with that in peri and postmenopausal status (p = 0.02). In multiple linear regression for muscle strength, the variables that remained were: age, estradiol and somatic symptoms measured by Menopause Rating Scale-MRS (R2=0.15). While for the xiv chair-stands test the predictors were number of births and FSH values (R2=0.04). Conclusion: There is a relationship between the stages of menopause and muscle performance in measures of grip strength and sit-up test and these are influenced by the fall of estrogens levels. Data suggest that the decrease in muscle strength and physical performance already appear in the transition to menopause stage, pointing to the need for more research in this area and appropriate preventive interventions

Brazil has been undergoing major demographic change.According to IBGE, the next 20 years the country's elderly population may reach over 30 million people. This tariff provides specifics regarding the process of health / disease. It is essential that higher education institutions are committed to this demand in view of the integrated training of health needs of society. The aim of this study is to analyze the Pedagogical Political Projects (PPP) of courses in dentistry in Rio Grande do Norte (RN), according to the national curriculum guidelines (DCNS) and training from the perspective of health care for the elderly. This is an exploratory study with a qualitative approach: with records and interviews. The study subjects were an Assistant Professor in the development of PPPs for each institution. The scenario in this study were dental training institutions in the newborns. Initially, the analysis of the PPP was by using the Alceste 4.9 software. The interpretation of the contents of interviews with teachers was done through content analysis of Bardin (2010). The PPPs are based on the DCNS, meet the characteristics of regional and seek a generalist, but still strongly directed to technical and scientific aspects of professional practice. Efforts and institutional approaches, involving teachers and students of the courses are being mobilized for training with more articulated network of health services. However, the emphasis on content pertaining to the health care of the elderly, is still limited when compared to those targeted content inherent in children and adolescents in all three curricular structures. It is reasonable to conclude that the historical, political, scientific, cultural and social, present in society, influence the formation of the dental professional RN. The greater participation of society in the process of vocational training in dentistry is needed. This can be done from the involvement of universities with health councils, bodies representing the dental profession and other segments of civil society in order to induce changes that generate ideas and educational practices integrative and interdisciplinary, with emphasis on continuing education for teachers, servants, employees and students. Containing conduct this process inherent flexibility of curriculum, teaching-service integration and coordination abilities and professional skills that are essential to understanding the human being and its complexities

The most common malignant neoplasm of the oral cavity and oropharynx are squamous cell carcinoma. Injuries to the same stage and subjected to the same treatment protocol have sometimes different evolutionary courses. The scope of this study was to investigate, through a retrospective cohort, associations between the number of CD8 + T cells and natural killer, identified immunohistochemically in the inflammatory infiltrate in a series of cases of oral squamous cell carcinoma and orofaringeano, and the level of tumor response to radiotherapy and chemotherapy, overall survival and relapse-free survival of patients. We identified 54 patients with unresectable disease were treated exclusively with radiotherapy and chemotherapy. The median follow-up was 22 months. The sample was characterized by the predominance of male subjects, median age 60 years, all were smokers. The most frequent site was the tongue and 81.5% were in stage IV. Patients with disease in the oral cavity had a worse response to treatment (p = 0.006), worse relapse-free survival (p = 0.007), worse overall survival (p = 0.007). The advanced T stage was shown a negative prognostic factor (p= 0.006) for the clinical treatment response made. Immunohistochemistry was performed to select CD8 + cells (anti-CD8) and NK cells (anti-CD57). Lymphocytes positive and negative markings were counted using the program ImageJ ®. Two groups were created for each marking evaluated: Group I patients with more than 50% cells positive, Group II: less than 50% of labeled cells. For CD8 + cells detected in 38 (70.3%) of Group I were CD8 + and 16 (29.7%) Group II CD8 +. For NK cells, 26 (48.15%) Group I NK and 28 (51.85%) Group II NK. Regarding the clinical response to treatment, we observed that 39% of patients achieved a complete response and 25.9% remained without recurrence at the end of follow-up. These results were better in Group I CD8 + (p = 0.2). Identified that 72.2% of patients progressed to death, this finding had no association with the immunohistochemical data. There was no statistically significant differences between the number of CD8 + and NK cells and the ability of tumor response to radiotherapy and chemotherapy, or with overall survival and relapse-free survival of patients. However, especially in relation to a learned response, we found that this group of patients with advanced disease have a low count of CD8 + T cells active. Believing in the role that the immune response plays in the local fight against neoplastic cells, however, our results do not support the use of quantitative analysis of CD8 + T cells and NK cells as a prognostic factors for oral squamous cell carcinoma and oropharynx

The increase of elderly population in the world and in Brazil has indicated the necessity of health systems capable to evaluate, to diagnose and to intervene in the conditions of health and disease of that segment. During that stage of human development, physical and cognitive changes happen and they are capable to influence the functional acting. It s important to distinguish the limit between the normal and the pathological. Besides the common changes during the aging, biological rhithmicity changes happen, as alterations in the cycle vigil-sleep that can influence in certain tasks performance. This study aimed to verify the influence of the age, of the sex and of the hour in a maze test performance. Eighty individuals were evaluated, 40 youths (20 men and 20 women) and 40 senior (20 men and 20 women). They were separated in 2 different groups that were tested at 9:00 o clock and at 15:00 o clock. Initially they were submitted to health evaluation, cognitive evaluation and of sleep quality and chronotype. They were instructed to accomplish the maze test whose time of execution was timed and registered. Significant differences were observed according to age for the masculine group between elderly in the morning and in the afternoon and in the feminine group between youth and elderly in the test accomplished in the morning and in the afternoon. Significant differences were not observed according to sex and hour of the day and also between attempts. In compare between the 30th and the31st, accomplished in a 15minutes of interval, significant difference was observed just for the elderly group in the morning and in the afternoon. We observed significant correlations in the maze test performance with the cronotype, with the age, with the education and with the cognitive acting. The maze test was capable to detect differences between age in the acting profile and in the evaluation of the information maintenance after 15 minutes, however it was not possible to verify difference between sex and hour of the day. Finally the correlations of the maze test with another varied may indicate your importance as coadjutant instrument in those functions evaluation

This research has as main proposal to verify how the virtue of generosity, considered as one of the important aspects of moral development on children, shows itself in children between four and six years old in institutional welcome condition. Toward this aim, knowledge in Human Development Psychology, specifically Jean Piaget and his contemporary collaborators, were associated to philosophic knowledge, with emphasis in Kant and Aristotle. The research took place in an institutional welcome service in the town of Natal-RN, between February and May of 2009, witch is responsible to offer care to children from zero till six years old. As procedure were used: the rulebased game Memory Game ; the childhood story One note fight ; and observations of the institution s everyday. The corpus analysis was done by the Thematic Content Analysis method. In general, in the daily observations, children showed themselves more co-operative and generous than in the executed procedures, mainly when the matter subject was other´s well-being. The duty, Kantian perspective, was overcome by the Aristotelian sumo bem, classified as generous act of afford to other what is not posted as right, however guaranteed by solidarity

Due to the need of increasing production in reservoirs that are going through production decline, methods of advanced recovery have frequently been used in the last years, as the use of conventional methods has not been successful in solving the problem of oil drifting. In this work, the efficiency of different microemulsionated systems in the flow of oil from cores from Assu and Botucatu formations. Regarding drifting tests, cores were calcinated at a temperature of 1000°C, for 18 hours, with the aim of eliminating any organic compound present in it, increasing the resultant permeability. Following, the cores were isolated with resin, resulting in test specimens with the following dimensions: 3.8 cm of diameter and 8.7 cm of length. Cores were saturated with brine, composed of aqueous 2 wt % KCl, and oil from Guamaré treatment station (Petrobras/RN). A pressure of 20 psi was used in all tests. After core saturation, brine was injected again, followed by oil at constant flow rate. The system S3 - surfactant (anionic surfactant of short chain), isoamillic alcohol, pine oil, and water - presented the best drift efficiency, 81.18%, while the system S1E commercial surfactant, ethyl alcohol, pine oil, and distilled water presented low drift efficiency, 44,68%

The generation of wastes in most industrial process is inevitable. In the petroleum industry, one of the greatest problems for the environment is the huge amount of produced water generated in the oil fields. This wastewater is a complex mixture and present great amounts. These effluents can be hazardous to the environmental without adequate treatment. This research is focused in the analysis of the efficiencies of the flotation and photo-oxidation processes to remove and decompose the organic compounds present in the produced water. A series of surfactants derivated from the laurilic alcohol was utilized in the flotation to promote the separation. The experiments have been performed with a synthetic wastewater, carefully prepared with xylene. The experimental data obtained using flotation presented a first order kinetic, identified by the quality of the linear data fitting. The best conditions were found at 0.029 g.L-1 for the surfactant EO 7, 0.05 g.L-1 for EO 8, 0.07 g.L-1 for EO 9, 0.045 g.L-1 for EO 10 and 0.08 g.L-1 for EO 23 with the following estimated kinetic constants: 0.1765, 0.1325, 0.1210, 0.1531 and 0.1699 min-1, respectively. For the series studied, the most suitablesurfactant was the EO 7 due to the lower reagent consumption, higher separation rate constant and higher removal efficiency of xylene in the aqueous phase (98%). Similarly to the flotation, the photo-Fenton process shows to be efficient for degradation of xylene and promoting the mineralization of the organic charge around 90% and 100% in 90 min

This work aims to study the influence of two additives, the monomer, acrylamide and its polymer, polyacrylamide, solubilized in microemulsion systems and applied on enhanced oil recovery. By the microemulsion system obtained, it was chosen points into the phase diagram, presenting these compositions: 25%, 30%, 35% C/T; 2% Fo (fixed for all points) e 73%, 68% e 63% Fa, respectively. However, the monomer and the polymer were solubilized in these microemulsion points with 0.1%; 0.5%; 1% e 2% of concentration, ordering to check the concentration influence at the physicochemical properties (surface tension and rheology) of the microemulsion. Through the salinity study, was possible to observe that the concentrations of 1% and 2% of polymer made the solution became blurred, accordingly, the study of surface tension and rheology only was made for the concentrations of 0.1% e 0.5% of monomer and polymer, respectively. By the surface tension study it was observed that how the concentration of active matter (C/T) was increasing the surface tension was amending for each system, with or without additives. In the rheology study, as it increases the concentration of active matter increases both the viscosity of the microemulsion system (SME) with no additive, as the SME with polymer (AD2). After the entire study, it was chosen the lower point of active matter (25% C/T; 2% Fo e 73% Fa), plus additives in concentrations of 0.1% and 0.5% to be used on enhanced oil recovery. Assays were made on sandstone from Botucatu Formation, where after the tests, it was concluded that among the studied points, the point who showed the best efficiency of advanced shift was the microemulsion system + 0.5% AD2, with a recovery of 28% of oil in place and a total of 96,49%, while the other solution with 0.5% of polymer presented the worst result, with 14.1% of oil in place and 67,39% of efficiency of total displacement

Nos últimos anos, o tema velhice tem despertado mais a atenção de diversos setores da sociedade. O resultado disso é o aumento de reportagens, artigos, monografias, dissertações e teses sobre ele.O Brasil está caminhando para se tornar a sexta população de idosos no mundo, fruto do grande avanço tecnológico, intensificado na segunda metade do século XX, facilitando as conquistas da medicina, da saúde e da genética. Vale salientar que essa problemática está inserida em um contexto social, político e econômico específico, que é o da resignificação do poder local. É nessa conjuntura que situamos o presente trabalho, que é um estudo sobre a avaliação de políticas públicas. Nesse sentido, procuramos analisar a efetividade do Programa Idoso Cidadão, da Prefeitura Municipal de Mossoró. O quadro de referência teórico-metodológico situa-se na revisão da literatura sobre terceira idade, poder local e avaliação de políticas públicas, observação assistemática; e entrevista semi-estruturada com os gestores, os profissionais envolvidos e particularmente com os usuários do Programa, tendo como meta averiguar como esses agentes percebem a implementação e os resultados do Programa. Com este tratamento conceitual foi possível apreender as condições em que se deu o estudo sobre a efetividade do referido programa para o processo de inclusão dos idosos na sociedade. O Programa Idoso Cidadão é, sem dúvida, um avanço no trabalho com os idosos e na inclusão destes na sociedade. É um espaço para a construção da cidadania, embora apresente muitas limitações, principalmente na área física e no quadro profissional. Constatou-se que, de modo geral, o Programa atende às necessidades básicas de sua clientela. Portanto podemos dizer que a avaliação da efetividade dessa política de atendimento ao idoso se mostrou eficaz, uma vez que podemos perceber o quanto o programa é importante para a vida de seus usuários, promovendo a elevação de sua auto-estima e de sua aceitação como categoria social

OBJETIVO: Avaliar se existe correlação entre qualidade de vida e classe funcional em pacientes no pós-implante de marca-passo cardíaco, e sua relação com idade. MÉTODOS: Investigados 107 pacientes de ambos os sexos (49,5% do sexo feminino e 50,5% do sexo masculino), tempo médio de implante 6,36º ±2,99 meses e média de idade 69,3º ±12,6 anos. Para avaliação da classe funcional, foi utilizada escala proposta por Goldman e para qualidade de vida, questionário AQUAREL associado ao SF-36. Realizada análise estatística pela correlação de Spearman, com significância de 5%. RESULTADOS: Foram observadas correlações negativas entre qualidade de vida e classe funcional: AQUAREL nos três domínios, desconforto no peito (r=-0,197, P=0,042), dispneia (r=-0,508, P =0,000), arritmia (r=-0,271, P=0,005) e, no SF-36 nos oito domínios. em relação à idade, correlação negativa com Capacidade Funcional do SF-36 (r=-0,338, P=0,000) e não se observou correlação com AQUAREL. Entre idade e classe funcional observou-se correlação positiva (r=0,237, P=0,014). CONCLUSÃO: Neste estudo, encontrou-se correlação negativa entre qualidade de vida e classe funcional, evidenciando nesta amostra que os pacientes pertencentes a melhor classe funcional apresentaram melhor qualidade de vida. Conforme maior idade, pior a qualidade de vida em Capacidade Funcional e em classe funcional. Sugere-se, que idade e classe funcional influenciam qualidade de vida e as escalas de classificação funcional podem constituir um dos instrumentos que integram a avaliação e refletem a qualidade de vida em portadores de marca-passo.

Tendo-se em conta a expectativa de vida cada vez mais alta, vários estudos têm sido desenvolvidos de modo a contribuir para a melhoria da qualidade de vida na terceira idade. Objetivou-se conhecer a opinião dos idosos de um município de porte médio do interior paulista sobre o que é qualidade de vida, através de uma pergunta aberta que foi incluída como parte de um inquérito populacional sobre estilo e qualidade de vida. A análise da referida questão foi realizada através do método de Análise de Conteúdo. Posteriormente calcularam-se as freqüências das categorias obtidas, agrupadas segundo o método de Ward, e em seguida os idosos foram agrupados segundo o método de k-médias. Os resultados indicaram a existência de três grupos de idosos segundo sua definição de qualidade de vida: o primeiro valorizou a questão afetiva e a família; o segundo priorizou a obtenção do prazer e conforto; o terceiro poderia ser sintetizado como o idoso que identifica a qualidade de vida colocando em prática o seu ideário de vida. Sugere-se que, na implementação de ações, se objetive melhorar a qualidade de vida do idoso, levando-se em conta as magnitudes e as diferenças de cada grupo.
