Uma análise sociodemográfica dos cuidadores formais de idosos institucionalizados no município de Natal/RN, 2012

The aging population and individual have been the subject of a multitude of studies nowadays. This is probably due to the impact of this phenomenon in various sectors of society, like social security, social assistance and public health. The process of aging of the individual imply the demand for specific services, considering the limitations and vulnerabilities of the individual at that stage of life cycle. The growth of the elderly contingent in the last decades raises challenges for policymakers, the family and also for the society at large. In this scenario, long-stay institutions for the elderly (LSIEs) appear as an option to aid and support the elderly and their family, assisting in all or part in the activities of daily living and self-care. Inside these LSIEs we find the professional responsible for the direct care of the elderly, the formal caregiver. In this context, this dissertation presents two main objectives: an analysis of the phenomenon of population aging in a given brazilian municipality Natal / RN, based on the Demographic Censuses of 2000 e 2010; and a social, demographic and economic characterization of the Formal caregiver for the institutionalized elderly in the municipality, evaluating aspects of his quality of life and also analyzing the institutions where they are inserted. Furthermore, we intend to identify demographic, socioeconomic and quality of life factors that are correlated with caregivers quitting the job. The data used in the second part of this work comes from the research project named Long-Stay Institutions for Elderly: abandonment or a family need? . This survey interviewed 92 caregivers in eleven LSIEs in Natal/RN. In the data treatment logistic regressions, cluster analysis and statistical tests were used. The survey revealed that aging in Natal is more pronounced in the older, more traditional districts: Petrópolis, Lagoa Seca and Tirol. It also allowed a broad characterization of the formal caregivers in LSIEs. Most of these professionals are female. The educational level is predominantly complete high school and more. Most caregivers reported being married or in union, or have ever been in a union. Family monthly income is under three times the minimum wage. The mean age is of 37.4 years. The mean time of work as a caregiver was 5.93 years. The associations showed that being woman, not being single, having caregiving training and physical limitations (regarding quality of life) are related to wanting to quit the caregiving job. As for the characterization of the LSIEs, it was found that the philanthropic ones are older and have most (62.5%) of the institutionalized elderly. The institutions managers gave social interaction and affinity with the elderly as the main criteria with which to evaluate and hire caregivers. It is intended with this study to contribute to improving the quality of life of the elderly and their caregiver, providing information on aspects of institutionalization of elderly both in the philanthropic and particular institutions, in Natal/RN; this dissertation may also be used as a starting point for later works

Utilização intracoágulo de espuma fibrinolítica - preparação, caracterização e atividade in vitro de uma espuma de estreptoquinase e proposta de uma nova abordagem terapêutica

Foam was developed as a novel vehicle for streptokinase with the purpose of increasing the contact time and area between the fibrinolytic and the target thrombus, which would lead to a greater therapeutic efficacy at lower doses, decreasing the drug s potential to cause bleeding. Fibrinolytic foams were prepared using CO2 and human albumin (at different v:v ratios), as the gas and liquid phases, respectively, and streptokinase at a low total dose (100,000 IU) was used as fibrinolytic agent conveyed in 1 mL of foam and in isotonic saline solution. The foams were characterized as foam stability and apparent viscosity. The thrombolytic effect of the streptokinase foam was determined in vitro as thrombus lysis and the results were compared to those of a fibrinolytic solution (prepared using the same dose of streptokinase) and foam without the fibrinolytic. In vitro tests were conducted using fresh clots were weighed and placed in test tubes kept at 37 ° C. All the samples were injected intrathrombus using a multiperforated catheter. The results showed that both foam stability and apparent viscosity increased with the increase in the CO2:albumin solution ratio and therefore, the ratio of 3:1 was used for the incorporation of streptokinase. The results of thrombus lysis showed that the streptokinase foam presented the highest thrombolytic activity (44.78 ± 9.97%) when compared to those of the streptokinase solution (32.07 ± 3.41%) and the foam without the drug (19.2 ± 7.19%). We conclude that fibrinolytic foam showed statistically significant results regarding the enhancement of the lytic activity of streptokinase compared to the effect of the prepared saline solution, thus it can be a promising alternative in the treatment of thrombosis. However, in vivo studies are needed in order to corroborate the results obtained in vitro

Correlação da atividade de lactato desidrogenase e concentração de lactato com a classificação de efusões em cães

As efusões são problemas clínicos frequentes e que ocorrem em consequência de uma enfermidade que culmine com diminuição da pressão coloidosmótica intravascular, elevação da pressão hidrostática local, aumento da permeabilidade vascular e/ou comprometimento da drenagem realizada pelos vasos linfáticos. Dessa maneira, a avaliação laboratorial desse fluido torna-se relevante para que, em conjunto com os sinais clínicos apresentados pelo paciente, possa ser firmado um possível diagnóstico e instituída ação terapêutica adequada. Assim sendo, a classificação de uma efusão em transudato ou exsudato torna-se um dos pontos críticos para a elucidação do diagnóstico e condução do caso clínico. em Medicina Veterinária, o método tradicional de classificação de uma efusão é baseado na contagem celular e na concentração de proteínas do fluido. Contudo, diversos estudos evidenciam que tais parâmetros não são suficientes para a correta classificação de todas as efusões. Assim, o presente estudo foi conduzido com o objetivo de verificar a correlação de outros parâmetros bioquímicos com a diferenciação das efusões transudativas e exsudativas e, para tal, foram avaliadas as atividades de lacatato desidrogenase (LDH) das efusões, a relação de sua atividade fluido/soro, concentração de lactato das efusões, o gradiente de concentração de lactato do soro para o fluido e a concentração de proteínas das efusões. Os resultados obtidos permitiram observar que a atividade de LDH, a relação LDH efusão/soro, a concentração de lactato e o gradiente de concentração de lactato soro/efusão apresentam diferença estatisticamente significativa (P<0,05), bem como alta correlação com a classificação de uma efusão exsudativa.

Avaliação da atividade turística sobre a composição e a distribuição das macroalgas marinhas nos recifes de Pirangi (Rio Grande do Norte, Brasil)

The reef area of Pirangi beach has been experiencing antropogenic actions, mainly due to tourism activity. In order to evaluate these effects, surveys on seaweeds were conducted at nine stations located over the fringing reef. Benthic community (seaweeds/corals) were identified using the photoquadrat method, with 50 meters random transects located paralleled to the coast. The general categories evaluated in each transect were: rock, sand, seaweeds, corals and mollusks. Data achieved were processed at Coral Point Count with Excel Extensions software. A total of 30 seaweed species, 5 coral species and 1 mollusk species were identified. There was a high dominance of short algae at stations with high tourism pressure, whereas frondose algae usually occurred at places without human interference. Seaweeds with the highest percent cover were composed by Sargassum vulgare (59%), Caulerpa racemosa (47%) and Dictyopteris delicatula (33%). Cluster analyses considering benthic organisms revealed five benthic features: (1) submersed area characterized by a diversified marine flora; (2) area with dominance of Caulerpa racemosa and presence of Millepora alcicornis; (3) area with high cover of Sargassum vulgare; (4) trampling area characterized by bare rocks, short algae and Zoanthus sociatus and (5) area with high coverage of Palythoa caribaeroum. Obtained data suggest that the studied area has been damaged by tourism activities. Furthermore, observed differences in algal communities may be a good indicator of ecosystem health of Pirangi reefs

A atividade eólica e o desenvolvimento regional: perspectivas na formação do pólo eólico no Rio Grande do Norte

The object of this study involves the eolian energy and the scenario the training of wind pole in Rio Grande do Norte. The aim is to investigate how far the implementation of the potiguar eolian pole may represent a regional development policy with real change in the structure of the traditional local productive base. About the interaction between the public and private to development of the local eolian activity, the hypothesis is that there is no coordination between the sectors responsible for eolian activity in the state. The theoretical approach follows the developmental current and theory of growth poles, and methodology adopted is a search of exploratory and documentary, with analysis of relevant documents on the subject. As a result of the study it was found that owing to the fragility of the productive structure potiguar and imbalances produced by the concentration of capital in the Northeast, the eolian activity in the state, needs a greater state-owned intervention to ensure a basis of development based on the study and strengthening local productive chain

Os saberes em potencial da atividade policial ostensiva: sistematizando modelos a partir da experiência potiguar

This work of research presents an investigation into the knowledge related to the ostensive policing activities of a group of the Rio Grande do Norte State Military Police Captains. This knowledge, which is decisive and part of Brazilian Military Police Constitutional matters, must be taken into consideration when it comes down to planning and putting into force the services related to ostensive public security. Thus, a historical and social analysis about the formation of the police by starting from foreigner experiences down to Rio Grande do Norte s reality, led by such knowledge, was made. Further, studying Brazilian and local scene, this knowledge was analyzed on the ostensive policing activities as for the principles of the Brazilian National Public Security Plan, Brazilian Classification of Occupations / CBO 2002, the reference documents and studies for police graduation Curricular Basis and Matrix; the Variables of Ostensive Policing, as well as some important competences of police service. Arguing that this knowledge is somehow related to what is presented in this work as Orientation Axis to Military Police Service , research tools such as Critical Case Solution and the answers to the Questionnaire on Fundamental Areas of Military Police Service , having in the end six knowledge models related to ostensive policing activities were used within that group. This knowledge can be classified in three distinct categories of connotations within the military police activity: one with reactive/repressive characteristics being the most predominant; the second as preventive; and another one that revealed that the military police activity is being misused for actions and/or missions outside the scope of action of military police

Histórias de idosos: sementes para cultivarmos uam educação para uma velhice bem-sucedida

We understand that the successful old age is not confined only in the analysis of quantitative aspects concerning the economic situation of the subject that gets old, but this special way of aging is related to other values, such as dignity, happiness, self-esteem, willingness, autonomy, independence, social involvement with family and friends, among others. Thus, this study aimed to investigate the human aging process, considering the history of life of ten seniors who fit the profile of successful old age, seeking to identify elements that contribute to educational thinking in order to get a successful aging. In this perspective, we argue in this study, the idea that we need to learn to engage in experiences that more than providing satisfaction and well-being in the moment in which we conducted, serve as a potentiating to a successful old age. Thus, throughout this thesis we question: what are the present indicative in the histories of life of elderly people, considered successful, which may contribute to an education that people experiencing their age more satisfactorily. This is a qualitative study, that took as universe a methodological oral history, in which we used as a technique of research a semistructured interview as a part of their life history, with emphasis on consideration of the following categories: diary routine, with emphasis on social harmony in the family, at work and in friendship groups of leisure and physical activity, self-knowledge and the learning experiences throughout life. To get the objectives outlined, as well as lectured on the categories analyzed, we support our reflection on the theory of the course of life, which includes human aging as a historical and cultural contextual reality. Our research revealed, among other things, that successful aging is coupled to an active lifestyle, where the involvement in physical activities, recreational and social experiences throughout life is important for increasing self-esteem, autonomy and joy of living, conditions that enable successful old age. Our study also revealed that the educationfor successful old age is linked with the consumption along the life, educational activities which broaden the possibilities of social interaction between people, even among different generations, since the interaction is important to learn and accept our possibilities and limits.

O presente estudo teve como objetivo determinar a ação antifúngica de extratos de plantas medicinais e óleo de eucalipto frente ao dermatófito Trichophyton mentagropytes, visando a utilização da fitoterapia no controle. As plantas utilizadas na obtenção dos extratos foram arruda (Ruta graveolens), citronela (Cymbopogon nardus), cravo de defunto (Tagetes minuta), eucalipto (Eucalyptus spp), graviola (Annona muricata), fruta do conde (Annona spp), manga (Mangifera indica), romã (Punica granatum), flores e folhas de primavera (Bougainvillea spectabilis). Verificou-se que uso de 0,5% óleo de eucalipto no combate ao T. mentagropytes foi eficaz, já os extratos de citronela (4%) eucalipto (5%) e romã (8%) atuaram como fungistáticos e os restantes não devem ser usados contra este dermatófito porque não causaram nenhum efeito.

A história escolar e a teoria da atividade: relações e possibilidades formativas no ensinar e aprender

This study investigates the manner in which the Activity Theory by Alexei Nikolaevich Leontiev contributed to the performance of a teacher who teaches History at the 8th year of elementary school, Escola Estadual Coronel Fernandes, in Luís Gomes - RN city. Her goal is to analyze the contributions of this theory in her teaching practice. It was opted by collaborative approach as formative strategy and was used as procedures for training of knowing the courses of study and thoughtful reflection sessions. It was used as techniques in the development of these cycles, the semistructured interview and the reflection sessions, the autoscopy and observation in real life. Regarding the theoretical foundation, held in these cycles, the teacher demonstrated to have appropriated some contributions from Activity Theory, besides relating them to her practice and understanding her importance to the improvement of teaching and learning of History. Concerning to the reflection sessions, the analysis showed that the participant has used of constructions of this theory and improved their practice, developing lessons of History so as to encourage student participation in oral and promote his integral development. The educational process, carried out on the practice of teacher, has shown an increase in her conscious learning that contributed to the improvement in their professional development. Before these findings, as needs for new thinking, this research recommends, especially the organization of teaching activities, based on this theory, which allows the teacher to improve the teaching and learning process contributing to student's full education

Associação entre consumo alimentar e atividade física com a síndrome metabólica em mulheres na pós-menopausa

Post-menopause is characterized as the period beginning one year after the permanent cessation of menstrual cycles, which is typically related to medical disorders that, in association with Metabolic Syndrome (MS), represent a set of cardiovascular risk factors. Objective: To assess dietary intake and the prevalence of metabolic syndrome in postmenopausal women, according to the level of physical activity. Methods: The sample consisted of 82 women, evaluated in the Northern Zone of the city of Natal / RN who were participants in the Natal Active Program. People completed a Food Frequency Consumption Questionnaire (FFCQ) and were interviewed about physical activity. Anthropometric measurements and biochemical tests were used to diagnose MS (Metabolic Syndrome). Result: The active women consumed more protective foods (flaxseed, nuts, whole wheat bread, brown rice and olive oil) than inactive women. Risky foods (sugar, crackers, white bread, white rice, margarine and beef) were consumed more by the group of inactive women. The prevalence of MS was higher in inactive women (53.30%) than in physically active women (46.70%). Conclusion: Active post-menopausal women had a higher daily intake of protective foods in relation to cardiovascular disease, while the inactive post-menopausal women had higher intake of risky foods for such diseases

Enxofre disponível para a soja e atividade de arilsulfatase em solo tratado com gesso agrícola

O constante uso de fertilizantes que não contêm S, aliado ao baixo teor de matéria orgânica de alguns solos, pode resultar em limitação desse nutriente para as culturas. Graças à alta mobilidade do íon sulfato no perfil da maioria dos solos, é importante conhecer o efeito residual da aplicação do gesso agrícola feita com a finalidade de fornecimento de S, visando estimar sua freqüência de realização. em dois anos agrícolas, foram efetuados experimentos em campo para avaliar o efeito da aplicação de gesso agrícola nos teores de S-sulfato, S-reserva e atividade da arilsulfatase de um Latossolo Vermelho distrófico cultivado com soja, bem como nos teores de macronutrientes nas folhas e na produtividade de grãos da cultura. Os tratamentos consistiram na aplicação de: 0, 67, 133, 267, 533 e 1.067 kg ha-1 de gesso agrícola, em delineamento inteiramente casualizado, com quatro repetições. Realizaram-se amostragens de solo nas profundidades de 0-20 e 20-40 cm a cada 21 dias durante o ciclo da cultura, totalizando seis por ano. A primeira amostragem de cada ano foi feita antes da aplicação do gesso. No segundo ano, a distribuição dos tratamentos foi feita sobre as mesmas parcelas do ano anterior. O gesso agrícola aumentou os teores de S-sulfato no solo nas épocas próximas à aplicação, os quais diminuíram com o tempo, em decorrência da precipitação pluvial. No primeiro ano, o S-sulfato foi lixiviado para além da profundidade de 20-40 cm, sem efeito residual de um ano para o outro. A atividade da arilsulfatase foi maior a 0-20 cm, de forma semelhante ao observado para o S-reserva, havendo correlação positiva entre essas variáveis. A aplicação de gesso agrícola não influenciou a produção de grãos e, à exceção do teor de S no segundo ano, não alterou os teores de macronutrientes nas folhas de soja.

Atividade de proteases e disponibilidade de nitrogênio para laranjeira cultivada em Latossolo Vermelho distrófico

O conhecimento do potencial da mineralização dos compostos orgânicos nitrogenados do solo é fundamental para o uso eficiente do N em sistemas de produção agrícola. Com o objetivo de avaliar a atividade de proteases e suas relações com os teores de diferentes formas de N em Latossolo Vermelho distrófico cultivado com laranjeira, foram coletadas amostras de solo em duas profundidades (0-10 e 10-20 cm), na linha de projeção da copa e nas entrelinhas, nos meses de novembro e dezembro/98, fevereiro e março/99. em março/99, época recomendada para a diagnose foliar, também foram coletadas amostras de folhas. As amostras de solo foram avaliadas com relação à atividade de proteases e aos teores de N-amoniacal, N-nitrato, N-total, N-amoniacal obtido após incubação anaeróbia (N-pot) e N-amoniacal extraído por solução de CaCl2 sob autoclavagem (N-autoclave). Nas amostras de folha, determinou-se o teor de N-total. A atividade de proteases foi influenciada pelo local e pela profundidade de amostragem, tendo sido mais elevada na linha de projeção da copa e profundidade de 0-10 cm. A aplicação de fertilizante orgânico causou aumento na atividade de proteases, principalmente na camada de 0-10 cm. O coeficiente de correlação entre atividade de proteases e outros métodos para avaliação da disponibilidade de N dependeu da época, do local e da profundidade de amostragem. A correlação entre o N-foliar, obtido na época indicada para diagnose foliar, a atividade de proteases e as demais formas para avaliar disponibilidade de N (N-amoniacal, N-nitrato, N-autoclave e N-pot) variou com a época de amostragem. A atividade de proteases foi positiva e altamente correlacionada com o N-foliar, obtido na época indicada para fins de diagnose foliar, para amostras de terra retiradas nas entrelinhas (0-10 cm), no mês de dezembro/1998.

Avaliação da atividade dos inibidores de tripsina após digestão enzimática em grãos de soja tratados termicamente

Este trabalho avalia a reativação dos inibidores de tripsina, após proteólise in vitro, de grãos de soja tratados termicamente. Para a inativação térmica dos inibidores, os grãos foram embebidos em água destilada (1:5 p/v) durante 12 horas e aquecidos em placas sob refluxo por 30 minutos. A reativação dos inibidores foi avaliada em comparação com a atividade das amostras cruas e aquecidas. A digestibilidade in vitro das proteínas variou de 47% ('OC-13') a 59% (Paraná), apresentando uma melhora, em média, de 32,6% com o aquecimento. A atividade dos inibidores de tripsina para os grãos crus variou de 122 a 206 UTI/mg de amostra, e os valores correlacionaram-se negativamente com a porcentagem de digestibilidade (r = -0,9177). Os inibidores tiveram suas atividades totalmente inativadas com o aquecimento dos grãos, os quais apresentaram porcentagem de recuperação, em média, de 40%. Com o aquecimento, a inativação dos inibidores provavelmente ocorre por complexação com os componentes do grão, o que leva à recuperação da atividade com o processo de digestão enzimática.
