Envelhecer entre pássaros e anjos: um estudo etnográfico sobre o processo saúde doença do idoso no contexto familiar

Study, a descriptive-like one, is guided by ethnographic principles which have analyzed the elderly within the familiar context in his/her process of health and aging, in the neighborhood called Felipe Camarão, located in the western administrative region of Natal, RN, a Northeastern city of Brazil. The participants are elders aging 61 to 84 years old, living in this referring neighborhood, whose majority is constituted of migrants from the rural region of the state of the RN, retired, including widows, widowers and married couples, with low school-educational degree. For the information gathering it was utilized a semi-structured interview, the participant observation and the field diary, being put into effect, in majority, in the houses and in the Family Health Unit, in a period between March and October of 2006. For the results discussion it was utilized an analysis of thematic content and the program ALCESTE (In Portuguese, Análise Léxica por Contexto de um Conjunto de Segmentos de Texto or Lexical Analysis by Context of a Set of Text Segments), which through have emerged two corpus: the corpus I, Family and the elderly, and corpus II, The elderly and the aging within society. The analysis of the results has permitted to conclude that the family, also used by the public policies as a strategy of their practices in health, it is a necessary base support for the elderly citizen in his/her process of aging and of health. The elders familiar contexts have allowed this study to identify the existence of minimal social conditions of life, of new rearrangements of the current families by means of the plurigenerational acquaintanceship and the active presence of the elderly woman as a maintainer of this family; also by means of conflicted relationships among one another but in a bearable level of acquaintanceship. Different conceptions about the aging and the elderly generate disagreement and divergency however the family support and help for the solving of these problems and the attention to health are proceeding from the family components. However, it is noticed that loneliness is something present in these elder s everyday lives. About the attention to health, in a basic level of it, it was noticed that there are still a lot of gaps, mainly concerning promotional and preventing actions, deserving a higher sensitization and effort by the local health institutions

A fragilidade e suas representações para idosos domiciliados no contexto da estratégia de Saúde da Família

This study aims to analyze social representations of elders to their fragile situation at home, with the presence of one or more characteristics, as defined by the Brazilian Ministry of Health. It is a descriptive and qualitative study, based on methodological -principles of the Theory of Social Representations. Setting was the homes of elderly residents in the area ascribed to a Family Health Unit (FHU) in the city of Natal. A total of 10 elderly subjects, whose choice was intentional and according to the need for USF home visit in a period of time, considering the saturation process of the information. As collection procedures were used the semi-structured interview and participant observation in accordance with the ethical rules of Resolution No. 196/96, with the assent of the Ethics and Research UFRN. To analyze the results, it was used the thematic content analysis in the aspect of preparation of representations, focusing on the totality of the discourse of the subjects. The results indicate that most study participants felt difficult to give meaning to the terms weakness and to be weak, although many present one or more aspects of the syndrome of frailty. From the content analysis of participants speeches in this study, we achieved the following categories: fragility as illness and disease as aging, aging and frailty as causes of changes and difficulties in daily life, the presence of family life in the fragile elderly, fragility as weakness and the risk for falls, the perception of being weak like a different person in addition to the absence of fragility in elderly life. Thus, through the processes of anchoring and objectification, the "fragile being" became familiar and concrete, showing that the meaning of weakness, besides the scientific definition found in the reified universes, can be reinterpreted and built within the consensus universes. About the care received by the staff of Family Health, from the viewpoint of older people there seems to be an understanding about the role of professional nurses; on the other hand, older people often mention the role of the Community Health Agent

Avaliação da capacidade para o trabalho do servidor público: um estudo de caso em uma instituição federal de ensino superior

The ability to work, considered as resulting from a dynamic process between the individual resources in relation to their work, influenced from various factors such as sociodemographic, lifestyle, aging process and requirements of work. Aiming analyze the ability to work in a population of public servants, the study analyzed 132 public servants volunteers of the infrastructure sector, in a Federal Institution of Higher Education of the state of Rio Grande do Norte, Northeast, Brazil. Data were collected through a questionnaire called the Index of Capacity for Work - ICT. The variable analysis was done by using descriptive statistics of means, standard deviations, median minimum and maximum values of the scores of quantitative variables. The joint analysis of the variables was performed by multiple linear regression. The server had low capacity to work 11 (8.33%), moderate 31 (23.48%), good 54 (40.91), and Great 28 (21.21). Multiple regression analysis, adjusted for age, sex, education, age started to work, length of service, current capacity and full of disease, showed that best explained the variation of the CTI were age, current capacity and full of disease. The survey showed that 75% of the servers showed ICT below 43, so capacity low, moderate or good and only 25% of respondents had the CTI servers over 43 points, so great capacity for work. According to the recommendations of FIOH - Finnish Institute of Occupational Health, for servers that have these scores be implemented whose objective is to restore the ability to work which is low, improving the capacity for moderate work, support the capacity for the good work and maintain the ability to work great. Therefore, we recommend that the ICT is implemented in other units of the IFES survey in the perspective of achieving a real situation of all its servers, enabling the implementation of these measures as necessary to promote recovery and health of its employees.

Prática do acolhimento à pessoa idosa na atenção básica: uma estratégia de humanização

The aging of the population already is a fact, before considered a phenomenon, today, is part of the reality of the majority of the societies in the world. The present study it has as objective to analyze the practical one of the shelter developed for the team to multidiscipline for the elderly in the Strategy of Health of the Family. One is about a descriptive and exploratória inquiry, developed by means of quantitative boarding. The population of this study consisted of nineteen teams that work in the inserted ESF in the urban zone of the city of Sousa-PB, understanding a complete of 133 professionals. The collection of date was carried through through a questionnaire contends closed questions, referring to the partner-demographic date e, specific open questions. The main results indicate that the professionals of Health of the city of Sousa, PB, that had participated of this study had consisted in a complete of 76. Amongst these, 20% are nurses, followed of the odontólogos in 6%; 35% are ACS and technician of nursing with 19%. The age of the interviewed ones meets in the age band enters, 21 and 30 years, in 43%. The majority is of the feminine sex with a 84% total. Already in accordance with civil state 34% is married. If treating to the wage, the doctor has of greater of 12 wages. The participants present the percentile greater of formed time of with referring 33% of 1 the 3 years of formation. E finally, the changeable time of performance, if had detached 39% of the participants with 08 the 11 years. With regard to as if it processes the reception and attendance to the person in the ESF, we can observe that, with priority attendance was prominence with 27% of the participants, followed of a considerate attendance with 26%. Already in relation to the actions that are developed daily in the ESF, these they are come back toward the HIPERDIA with 40%, followed of actions ruled in orientation with 27%. Some actions they are carried through in accordance with the aged necessity of each (13%) and through visits domiciliary (9%). It was asked to them as the shelter was facilitated in the UBS, these had told that it is through the attention that is excused the aged one (35%), and finally, as this made it difficult age, in its majority with 37% they had not wanted to answer, followed of the lack of understanding with 26%. With this study it was possible to conclude that the practical one developed for the professionals of the ESF of the city of Sousa, PB with the elderly, is characterized by an assistance ruled in the clinical aspect, little focused in the actions that to permeate the PNH

O cuidar de enfermagem e da família à pessoa idosa no domicílio: uma abordagem etnográfica

O envelhecimento é um processo multidimensional que envolve entre outros os aspectos físico-biológicos, sociais, econômicos e psicológicos. Ao avaliar essa fase da vida dentro de uma visão social e cultural, percebe-se que ser idoso ou não varia com as concepções culturais, sendo necessário investigar as variações que atuam no processo e rege o fenômeno sociocultural da realidade em que se está inserido. Com o aumento da população idosa mundial, esse processo tende a se intensificar. Estima-se que até em 2050 existam cerca de dois bilhões de pessoas com mais de 60 anos no mundo, e a maioria delas vivendo em países em desenvolvimento. No Brasil, acredita-se que existam, atualmente, cerca de 20 milhões de idosos. A normatização e legislação brasileira de amparo ao idoso em relação à saúde iniciaram-se a partir da Constituição Federal de 1988 e da Lei 8080 que regulamenta o Sistema Único de Saúde em 1990, em seus níveis de complexidade: atenção básica, média e alta complexidade. Para auxiliar nessa prestação dos serviços na atenção básica de saúde é importante observar as condições sociais, culturais, econômicas e de saúde dos idosos e seus familiares. Nesse sentido, a visita ao domicílio e a avaliação deste idoso em seu ambiente doméstico torna-se fundamental para acompanhar o cuidar prestado e o quanto esse processo irá interferir no sistema de saúde, na família e na qualidade de vida dos idosos. Neste contexto, o enfermeiro como integrante da Equipe de Saúde da Família, presta assistência à saúde do idoso no domicílio. Nesse sentido, o objetivo do estudo é analisar o cuidado de enfermagem e da família à pessoa idosa no domicílio com vistas à identificação das influências socioculturais. Trata-se de um estudo do tipo descritivo e de abordagem qualitativa, norteados por princípios teórico-metodológicos da etnografia com vistas ao estudo da influência dos aspectos culturais e sociais na assistência da família e do enfermeiro à idosos em domicílio. Foi realizado no município de Santana do Matos, RN, tendo como participantes, idosos, familiares e enfermeiros da equipe da ESF, definidos a partir da população do município e obtendo-se uma amostra intencional de 25 participantes: 6 enfermeiras, 10 idosos e 9 grupos familiares. Para a coleta de informações, utilizou-se observação, entrevista, diário de campo e grupo focal. Os resultados foram apresentados em forma de narrativa descritiva, na perspectiva dos conceitos de Boris Cyrulnik, com análise interpretativa cultural de Geertz, na busca dos significados e símbolos próprios da cultura da velhice de idosos e dos seus familiares, sobre cuidados que são realizados, tanto pela família, como pelos enfermeiros em domicílio. Observou-se que a família e o cuidador, dentro de sua realidade social e cultural, precisam ser mais compreendidos pela equipe de saúde para ser melhor orientados e capacitados na realização do cuidar de forma adequada. Por sua vez, os profissionais de saúde, em especial o enfermeiro, enfrentam dificuldades para realizar o cuidado ao idoso no domicílio como a grande demanda de atribuições na unidade de saúde como consultas e atendimentos; falta de transporte até os domicílios; extensão territorial do município e das áreas assistidas; número de pessoas atendidas por cada equipe; falta de compreensão dos profissionais de saúde quanto à importância da visita domiciliária na atenção básica. Entendem a necessidade de realizar ações de promoção em saúde, prevenção de agravos e de educação em saúde, além de reconhecerem a importância de uma melhor formação acadêmica para atuar nessa perspectiva e contribuírem para as mudanças necessárias na prática dos cuidados ao idoso em domicílio

A pessoa idosa com doença crônica não transmissível atendida em serviços de média complexidade na cidade de Natal/RN

The demographic and epidemiological transition process caused by a declining in birth rates and in mortality, also changes occurred in morbidity and mortality is represented by the increasing of the aging population and the raising of chronic diseases. These diseases are characterized by multiple etiologies, risk factors, long latency period, a prolonged evolution, non-infectious origin and it has association with functional impairment and disability. Thus, elderly with chronic non-communicable disease has priority because they belong to a vulnerable group to get affection of comorbidities in aging, with increased demand and spending on health services. This study is aimed to analyse the understanding of elderly people with chronic non comunicable disease in the medium complexity service as a contribution to the improvement of health care in the city of Natal / RN. This is a descriptive and exploratory study with a quantitative approach, carried out at the Specialized Center for Elderly Health Care and at the Pescadores Hospital. The population was composed of 4,180 persons with a sample of 124 elderly aged above 60 years, attended in these medium complexity services. The instrument, a structured form, adapted from a questionnaire for monitoring risk and protective factors for chronic disease of the Ministry of Health. To collect data was was used the interview form containing demographic data, habits, health status and health care services. The results were processed using the Statistical Package for Social Science, version 18.0, analyzed by simple statistics. It was found that most seniors were female, predominantly between 70 and 74 years old, married, with a brown skin tone and Catholic religion, more than half had incomplete basic education, family income between one to two minimum wages and living with their families. Regarding the interviewers lifestyle, 94.4%, of them ate chicken and 97.6%, fruits, it was observed a reduction in smoking, alcoholism habits and physical activity according to the increasing age, 58.1 and 18.5% had insomnia18,5 % used sleeping pills. The elderly (51.6%) reported using services in times of sickness, seeking primary care at first (30.6%), 52% did not receive referral and was looking for free demand (38.7%). The most reported morbidity was hypertension, followed by musculoskeletal disorders. Regarding the difficulties in seeking health services, the delay in treatment and the waiting line were the most cited by the elderly. Almost all of them reported no activities to promote health in these services and those who received individual counseling on chronic diseases. Almost always, the health professionals who care of them, were mostly doctors followed by nurses. Based on the results presented, it is considered that the health services of medium complexity must undergone a more continuous dialogue with other attention level and focus on actions of health promotion and prevention. It is also recommended the necessity for qualified professionals to delivery health care to elderly and the implementation of protocols by a multidisciplinary health team, intending to provide better and continous care for the elderly with chronic diseases. The healthcare professionals who served them, were mostly physicians, followed by nurses. Through the results presented, it is considered that the medium complexity healthcare services need to perform a more continuous dialogue with the other levels of attention focusing attention to the health promotion and prevention actions. It is also recommended the necessity for qualified professionals to delivery healthcare for the elderly, in addition, a protocol implementation for the multidisciplinary health care team, to provide better care, and also the care continuity to elderly with chronic diseases

Atenção à saúde da pessoa idosa na estratégia saúde da família no município de Santo Antônio/RN: um estudo de caso

According to demographic estimates, by the year 2025 Brazil will be the sixth country in the world in number of elderly. For this reason, it is a purpose of public policies to help people to reach that age being healthier. The current health care model of health surveillance through the Family Health Strategy (EFS, in portuguese) is configured as a gateway into the care of the elderly in the Unified Health System (SUS, in portuguese). It is also an area of development of practices to promote health, prevention and control of chronic nondegenerative diseases. The aim of this study was to analyze the health care of the elderly provided by ESF professionals for the achievement of a full care. The study is descriptive case study with a quantitative approach, performed in the city of Santo Antônio/RN. The population included all health professionals, who are FHS members of the city that agreed to participate of the survey, a total of 80 professionals. Data were collected using a structured questionnaire, having mostly closed questions and divided into two parts: one containing sociodemographic information of health professionals and vocational training and the other, the activities carried on by the professionals in senior care, being analyzed from a database tabulated in a spreadsheet and discussed according to the descriptive statistics in tables, graphs and charts using frequencies, medians and values of central tendency. It was verified a predominance of professionals who finished highschool, mostly female, aged from 30 to 34 years old, with training completed in the last 10 years, without being graduated in the field of geriatrics or gerontology and mostly without training in gerontology. Family members and caregivers were the components of the social support network most identified by the professionals (66.3%).The elderly access to the Family Health Basic Unit was considered by83.8% of professionals as the most important factor that interferes in the activities of health care of the elderly. Considering the inclusion of the family in care: 98.8% of professionals consider the family as one of the goals of care, but 82.5% assist the family to know their role and participate in the care of the elderly, emphasizing that no professional makes use of tools for evaluating the functionality of the family. Regarding the actions taken to assist the elderly, 91.25% have home visits program to the elderly, 88.75% use the host program; 77.5% know the habits of life, cultural, ethical and religious values of the elderly, their families and their community ;51.25% complement the activities through intersectoral actions, 50%participate in groups of living with the elderly; 33.75% keeps track and maintain updated the health information of the elderly; 11.25% of the professionals perform the Single Therapy Planning (PTS, in portuguese) and few implement the actions to promote health according to PTS; there is a deficit in the number of professional categories in the identification and monitoring of the frail older people in their households. It is concluded that the health care of the elderly developed by ESF professionals differs among the professional categories. It was identified weaknesses in the promotion of an active and healthy aging and also in the establishment of an integrated and full care of the elderly. It is recommended the adoption of permanent educational activities by the City Management, initially for ESF professionals in the the perspective of the guidelines of the National Policy of Health Care for the Elderly and later to the other professionals that are part of the health care network of the elderly, at all levels of care in the city for the development of strategies and practices that promote the improvement of the quality of healthcare for the elderly, expecting concrete and effective results in terms of promoting health within Brazilian reality

O ensino de enfermagem gerontológica na formação do enfermeiro

At the current time of demographic changes in the world , it is observed that the health sector requires restructuring of its practices in caring for the elderly , in order to enable a comprehensive and humane care . In this sense, we identify the need for qualified professionals to assist the elderly and, therefore , it is important that training curricula are adequate to this reality . The study aims to analyze how it develops teaching gerontological nursing component in undergraduate nursing . This is a descriptive , exploratory study with a qualitative approach, in two higher education institutions in the city of Natal / RN . The population involved corresponded to the coordinators of graduate courses in nursing and teachers who teach content of health care for the elderly, a total of seven participants . The data collection instruments were used: a questionnaire containing questions related to the characterization of the participants and the teaching of gerontological nursing in undergraduate courses in nursing and a form with items of analysis for pedagogical projects . The results were presented descriptively in tables and analyzed from coming themes of the main themes of the instruments defined in: knowledge about the research participants , knowledge of teaching gerontological nursing component and knowledge of pedagogical projects , discussed under Resolution paragraph . 03 of 7/11/2001 , which establishes standards for the nursing program , the educational projects of educational institutions , the Theoretical Donald Shoon and thematically relevant literature . The results indicate that the majority of participants were female (four), all have graduate though , none of them stated in the qualification of aging or elderly health area; the organization of the contents of the component in the curriculum, workload theoretical- methodological and practical teaching strategies presented was heterogeneous and sometimes diverging at the same institution . On the definition of gerontological nursing component was identified that is not well defined along the pedagogical design of educational institutions surveyed . It was concluded that in the context of this study , teaching gerontological nursing is present in the course of nursing education, but needs reevaluation and updating in order to teach a wider range of driving and health practices

Abordagem da ergonomia para a análise da acessibilidade de uma instituição de longa permanência para idosos da cidade de Natal-RN

This dissertation presents and discusses the results of an applied research on the accessibility of residents in a Long Term Care Institution (LTCIs) in the city of Natal- RN. The main objective of this research is to suggest projectual improvements that maximize the accessibility in a LTCIs of Natal-RN, considering the aspects of mobility, safety, comfort and independence of elderly residents. Moreover, one should consider the specific characteristics of the user population, capabilities and limitations of the biological process of aging, which causes damage to the neurological system, musculoskeletal and cardiovascular and progressively affects on visual acuity, balance and locomotion of elderly people. This research has a qualitative approach and divided into four phases: exploratory, bibliographical and documentary research, mapping of the LTCIs of Natal-RN, case study. The phase of the mapping presented an overview of accessibility on LTCIs of Natal-RN. The institution of the case study was defined based on the overall assessment of accessibility and ergonomics criteria, preceded by an application of an Ergonomic Work Analysis to understand the accessibility of the elderly people. Interactional and observational methods were used to collect field data. To this end, an intense process of social construction was conducted, involving the elderly residents, caregivers, health professionals and general servants and LTCIs´ managers. It was found that the NBR 9050 is not comprehensive to solve the diversity of accessibility problems found in LTCIs. All LTCIs investigated were in disconformity to the NBR 9050. In the case study, it was found that the inappropriate design hinders the daily activities of the elderly people and is a source of risk of accidents. The environment, facilities and lack of assistive technologies hinder the autonomy of the elderly people, and this LTCI requires ergonomic intervention to improve the accessibility, autonomy and security of the elderly people

Efeitos da radiação uv, temperatura e vapor aquecido nos compósitos poliméricos: monitoramento, instabilidade estrutural e fratura

The application of composite materials and in particular the fiber-reinforced plastics (FRP) has gradually conquered space from the so called conventional materials. However, challenges have arisen when their application occurs in equipment and mechanical structures which will be exposed to harsh environmental conditions, especially when there is the influence of environmental degradation due to temperature, UV radiation and moisture in the mechanical performance of these structures, causing irreversible structural damage such as loss of dimensional stability, interfacial degradation, loss of mass, loss of structural properties and changes in the damage mechanism. In this context, the objective of this thesis is the development of a process for monitoring and modeling structural degradation, and the study of the physical and mechanical properties in FRP when in the presence of adverse environmental conditions (ageing). The mechanism of ageing is characterized by controlled environmental conditions of heated steam and ultraviolet radiation. For the research, it was necessary to develop three polymer composites. The first was a lamina of polyester resin reinforced with a short glass-E fiber mat (representing the layer exposed to ageing), and the other two were laminates, both of seven layers of reinforcement, one being made up only of short fibers of glass-E, and the other a hybrid type reinforced with fibers of glass-E/ fibers of curaua. It should be noted that the two laminates have the lamina of short glass-E fibers as a layer of the ageing process incidence. The specimens were removed from the composites mentioned and submitted to environmental ageing accelerated by an ageing chamber. To study the monitoring and modeling of degradation, the ageing cycles to which the lamina was exposed were: alternating cycles of UV radiation and heated steam, a cycle only of UV radiation and a cycle only of heated steam, for a period defined by norm. The laminates have already undergone only the alternating cycle of UV and heated steam. At the end of the exposure period the specimens were subjected to a structural stability assessment by means of the developed measurement of thickness variation technique (MTVT) and the measurement of mass variation technique (MMVT). Then they were subjected to the mechanical tests of uniaxial tension for the lamina and all the laminates, besides the bending test on three points for the laminates. This study was followed by characterization of the fracture and the surface degradation. Finally, a model was developed for the composites called Ageing Zone Diagram (AZD) for monitoring and predicting the tensile strength after the ageing processes. From the results it was observed that the process of degradation occurs Abstract Raimundo Nonato Barbosa Felipe xiv differently for each composite studied, although all were affected in certain way and that the most aggressive ageing process was that of UV radiation, and that the hybrid laminated fibers of glass-E/curaua composite was most affected in its mechanical properties

Resposta térmica de um compósito PEEK+PTFE+Fibra de carbono+grafite

Composites based on PEEK + PTFE + CARBON FIBER + Graphite (G_CFRP) has increased application in the top industries, as Aerospace, Aeronautical, Petroleum, Biomedical, Mechanical and Electronics Engineering challenges. A commercially available G_CFRP was warmed up to three different levels of thermal energy to identify the main damage mechanisms and some evidences for their intrinsic transitions. An experimental test rig for systematize a heat flux was developed in this dissertation, based on the Joule Effect. It was built using an isothermal container, an internal heat source and a real-time measurement system for test a sample by time. A standard conical-cylindrical tip was inserted into a soldering iron, commercially available and identified by three different levels of nominal electrical power, 40W (manufacturer A), 40W (manufacturer B), 100W and 150W, selected after screening tests: these power levels for the heat source, after one hour of heating and one hour of cooling in situ, carried out three different zones of degradation in the composite surface. The bench was instrumented with twelve thermocouples, a wattmeter and a video camera. The twelve specimens tested suffered different degradation mechanisms, analyzed by DSC (Differential Scanning Calorimetry) and TG (Thermogravimetry) techniques, Scanning Electron Microscopy (SEM) and Energy-Dispersive X-Rays (EDX) Analysis. Before and after each testing, it was measured the hardness of the sample by HRM (Hardness Rockwell M). Excellent correlations (R2=1) were obtained in the plots of the evaporated area after one hour of heating and one hour of cooling in situ versus (1) the respective power of heat source and (2) the central temperature of the sample. However, as resulting of the differential degradation of G_CFRP and their anisotropy, confirmed by their variable thermal properties, viscoelastic and plastic properties, there were both linear and non-linear behaviour between the temperature field and Rockwell M hardness measured in the radial and circumferential directions of the samples. Some morphological features of the damaged zones are presented and discussed, as, for example, the crazing and skeletonization mechanism of G_CFRP

Extração, caracterização e avaliação bioativa do extrato de Rumex acetosa

Studies show the great influence of free radicals and other oxidants as responsible for aging and degenerative diseases. On the other hand, the natural phenolic compounds has shown great as antioxidants to inhibit lipid peroxidation and lipoxygenase in vitro. Among these, is highlighted trans-resveratrol ( 3,5,4 `- trihydroxystilbene ) phenolic compound , characterized as a polyphenol stilbene class. The vegetables popularly known as "Azedinha" (Rumex Acetosa) has trans-resveratrol in its composition and from this, the present work aimed to study on the supercritical extraction and conventional extraction (Soxhlet and sequential) in roots of Rumex Acetosa, evaluating the efficiency of extractive processes, antioxidant activity, total phenolic content and quantification of trans-resveratrol contained in the extracts. Extractions using supercritical CO2 as solvent, addition of co-solvent (ethanol) and were conducted by the dynamic method in a fixed bed extractor. The trial met a 23 factorial design with three replications at the central point, with the variable reply process yield and concentration of trans-resveratrol and pressure as independent variables, temperature and concentration of co-solvent (% v/v). Yields ( mass of dry extract / mass of raw material used ) obtained from the supercritical extraction ranged from 0,8 to 7,63 % , and the best result was obtained at 250 bar and 90 °C using the co-solvent 15% ethanol (% v/v). The value was calculated for YCER a flow rate of 1,0 ± 0,17 g/min resulting in 0,0469 CO2 ( g solute / g solvent ). The results of the mass yield varied between conventional extractions 0,78 % ( hexane) and 9,97 % (ethanol). The statistical model generated from the data of the concentration of trans-resveratrol performed as meaningful and predictive for a 95% confidence. GC analysis on HPLC (High Performance Liquid Chromatography), transresveratrol was quantified in all extracts and concentration values ranged between 0,0033 and 0,42 ( mg / g extract) for supercritical extracts and between 0,449 and 17,046 (mg / g extract) to conventional extractions and therefore, the Soxhlet extraction with ethanol for more selective trans-resveratrol than the supercritical fluid. Evaluation of antioxidant (radical method to sequester 2,2- diphenyl-1- picryl - hydrazyl - DPPH) the supercritical extracts resulted in EC50 values (concentration effective to neutralize 50% of free radicals) of between 7,89 and 18,43 mg/mL , while resulting in a Soxhlet extraction with EC50 values in the range of 6,05 and 7,39 mg/mL. As for quantification of the phenolic compounds (Method Spectrophotometer Folin-Ciocalteau) the supercritical extracts resulted in values between 85,3 and 194,79 mg GAE / g extract, whereas values derived from the Soxhlet extract resulted in values between 178,5 and 237,8 mg GAE / g extract. The high antioxidant activity can not be attributed solely to the presence of phenolic compounds, but the presence of other antioxidants in the existing Rumex acetosa

Efeito da estrutura etária nas taxas de homicídios em regiões metropolitanas brasileiras (Natal - Recife - São Paulo)

Este estudio examina el fenómeno de asesinato, desde la perspectiva de cambiar la estructura de edad de la zona metropolitana de Natal, Recife y Sao Paulo, utilizando los datos del Sistema de Información de Mortalidad-SIM/DATASUS, del Ministerio de Salud. Se llevaron a cabo ejercicios teóricos estandarización directa con las estructuras de diferentes edades para evaluar el efecto de los cambios en la estructura de la población en las tasas de mortalidad por homicidio. Los resultados presentados en las pirámides de edad y las cartas apuntan a la población de edad avanzada en las tres áreas metropolitanas de la serie analizada, así como las que muestran un mayor riesgo de victimización en las personas, hombres, de edades comprendidas entre 15 y 39 años. Hemos utilizado diversos ejercicios de las tasas de homicidios con patrones estandarizados de distintas edades, incluyendo una población proyectada para el año 2020 de la Región Metropolitana de São Paulo, cada vez más evidente que cuando la población se vuelve más edad con menos gente en los grupos de mayor riesgo tienden a tener menores tasas de muertes por homicidio, también puede presentar otros resultados siempre la misma línea de razonamiento

Força muscular respiratória e capacidade funcional em idosas hipertensas com sonolência diurna excessiva

The restriction of physical fitness is directly related with hypertension and sleep disorders, while the respiratory muscle strength is associated with hypertension, but the literature is scarce regarding its relationship with sleep disorders and particularly with excessive daytime sleepiness. Objectives: To compare physical fitness and strength of respiratory muscles between people with hypertension with excessive daytime sleepiness (EDS) and non EDS people, those who do not feel excessive daytime sleepiness, in addition to relate aerobics resistance and functional mobility of patients. Methods: An observational, analytical and transversal study, evaluated 32 elderly with hypertension, divided into two groups (EDS and non EDS), in which the following topics were measured; respiratory muscular strength, functional fitness, level of physical activity, level of excessive daytime sleepiness, quality of sleep and intensity of the patients snoring. Results: There was a significant difference in the level of EDS (P=0,00) and quality of sleep (p=0,03), however, the data related to snoring intensity (p=0,18), maximum inspiratory pressure PImax (p=0,39) and maximum expiratory pressure PEmax (p=0,98) did not show any difference. Also, no significant difference was observed concerning physical fitness, presenting p=0,08 for the sitting and getting up test on the chair in 30 ; p=0,54 for the extension and flexing of the elbow test in 30 ; p=0,38 for the walking test 6 ; p=0,38 for the parking gear test 2 , p=0,08 for the sitting and reaching test; p=0,42 for the scratching the back test; p=0,49 for the getting up and walking test; and p=0,62 for the global rate of activity limitation. There was moderate positive correlation between 6MWT and 2MST, r=0,54 (p=0,01) and negative moderate correlation between 6MWT and TUG, r=-0,61 (p=0,000) and between 2MST and TUG, r=-0,60 (p=0,000). Conclusion: The presence of EDS in the hypertension people studied, showed a bad quality of sleep, however this sleepiness did not influence the strength of the respiratory muscles. The physical fitness came out diminished in all hypertension people, regardless of the presence or non presence of sleep disturbance; and there is a close relationship between cardiovascular resistance and physical mobility, since when there is less cardiovascular resistance, there is precarious physical mobility and vice-versa
