Ações de profissionais relativas ao banco de leite humano : uma perspectiva de mudança

This is an exploratory and descriptive study that aimed to investigate the actions of professionals in the context of breastfeeding, on the assumption that the actions taken by employees working together to postpartum and newborn are not competing to effect the distribution of pasteurized human milk so that it meets the needs of infants who depend on it. Thus, the study aimed to analyze the actions of medical and nursing staff of the distribution of pasteurized human milk to the newly born. The investigation was developed by action research in a federal hospital, located in the capital the state of Rio Grande do Norte, Brazil, reference assistance to women during pregnancy, childbirth and postpartum high risk in 2010. Study participants were fifty-five professionals chosen from the following inclusion criteria: to act in the NICU or rooming, being a pediatrician and / or neonatologists, nurses and technical nursing. According to the methodology of action research a questionnaire was applied, techniques in focus groups and courses were developed, and, finally, action evaluation. The project was submitted to the Ethics Committee at the Federal University of Rio Grande do Norte and approved with no protocol 448/2009. The problems identified in the responses issued by the social research were grouped into categories according to the similarity between them. The answer to the question of the survey - How is the need for pasteurized human milk for the newborns in neonatal intensive care unit and rooming identified? - Brought subsidies for action planning and implementation of strategies for change in the practice of professionals working in rooming and ICU. Thus, the study has relevance in social care and, when at the local level, will compete for the distribution pasteurized human milk to take effect as best as possible, as recommended by the Ministry of Health. It is also conceived that, in a macro view of society, it could contribute to minimizing the health problem that involves the child population

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

And by means of univariate logistic regression, showed that the nurses and male sex were risk factors for the occurrence of WRA. We conclude that there were gaps in the knowledge of staff regarding WRA, emphasizing the need for continuing education in biosafety in the service.

Aconselhamento em HIV/AIDS: ações e reflexões dos profissionais do Centro de Testagem e Aconselhamento (CTA)

The counseling on HIV/Aids consists in a prevention strategy that contributes to increase the diagnosis of HIV and start earlier the treatment. The counseling has as pillars the emotional and educational support, risks evaluation that aim at the adoption of safe practices and the individual s responsibility for his own health. To accomplish these results, it is necessary that health workers understand counseling as a unique educational moment that stimulates the user s critical-reflection when it comes to his role as an active subject in this process. This study aimed to analyze the counseling on HIV/Aids conducted by the professionals of the Testing and Counseling Center (CTA), based on the educational perspective of Paulo Freire . This is a descriptive qualitative study with a critical reflexive design based on the principles of Action-Science. All the professionals acting as counselors in the Joao Pessoa, PB CTA, eight in total, took part in the study. Data were collected during the month of March, 2011, through non participative observation and semi-structured interviews with a critical-reflexive focus, analyzed according to the tenets of the critical-reflexive methodology, and discussed taking into consideration the Paulo Freire s pedagogy and pertinent literature. It was observed that most of the professionals expressed the work philosophy of CTA as the diagnosis and prevention of the disease, associated with the utilization and demonstration of condoms. However, upon observation of their counseling sessions, these ideas were not converted in actions. Educational themes were not covered and the condom wasn t offered at any time. The counseling actions focused on the provision of information and filling out the paper forms which are necessary for attendance. The sessions were conducted with brief dialogues and little opportunity for the users to expose or complement their thoughts and needs. The professionals mentioned as facilitating conditions for counseling, the team interaction and physical structure. The difficulties focused on the users low cognition, the large demand for attendance, aspects related to the service organization, and the counselors absences and delays. After reflecting about the actions observed in the counseling, the majority of professionals admitted the need to modify their practice in the incorporation of educational principles for the achievement of a broader prevention, and seemed to be willing to work in this perspective. In conclusion, although the counselors show ideas consistent with the purposes of CTA, these ideas are limited when it comes to the understanding of the meaning of prevention in HIV/Aids. Taking into consideration that they express a certain comprehension and act differently during the counseling, they demonstrate a lack of bond between the theories in use and the proposed ones, in accordance with the contribution of the action-science theory. The counseling, as an educative practice, doesn t materialize in the counseling itself and the orientation for reflection is not given during the attendance. These findings suggest the need to include the process of reflection in the execution of the actions of counseling, so that these practices are guided by reflexive practice, aiming at transforming the way of thinking and acting into a more educational perspective toward a more democratic and holistic assistance.

Ensino do processo de enfermagem: visão dos discentes de graduação de Natal/RN

The nursing process (NP) it s the systematized way of offering humanized care with the objective of reaching the expected results. The concern of the health and education institutions of elaborating implementation strategies of it is growing. The objective of this research was to know the vision of the senior students of the nursing graduation courses from Natal/RN, about the teaching of the NP. It s about a descriptive and exploratory study of the qualitative and quantitative type, done in five teaching institutions of the undergraduate nursing course of the municipality of Natal- RN in 2011. The research was composed by 48 students of the last 2 years of the nursing course. The gathering of the data was done through an online survey with open and closed questions via SurveyMonkey. For the quantitative data it was used the descriptive statistics from Microsoft Office Excel and for the qualitative data the Content Analysis of Bardin. The results pointed a predominance of female students (81,25%) with an age between 21- 39 years old (75,00%) and in the last year of the course (62,50%). As the opinion of the students about the NP two categories emerged: 1) Nursing Process as grounded method in scientific knowledge and established in two stages; 2) Nursing Assistance Quality, with two subcategories: Nursing Process as Nursing Practice and Nursing Process as instrument of improvement of the aid quality and promotion of well-being. In relation to the tuition of the NP the students (45,83%) said that the knowledge on the subject of the instructor was good; 81,25% reported that the professors use a traditional teaching methodology with the problem solving components and 45,83% answered that is addressed in specific disciplines in an isolated way starting from the professional line. The phase of NP that the nursing students have more difficulties of learning and implementing, being mentioned 22 times (29,70%). In relation to the student s difficulties, in the fields of supervised internships, in applying the NP it was stated for 83,50% that the barriers were related to the non implementation of the practice, overwork and the lack of trust of the nurse in the NP. The teaching-care strategies described as the internship fields were: the training of nurses to be able to contribute with the University in the implementation of the service and teaching; and the need of the universities to focus, continuously throughout the course, the NP with the involvement and incentive of the instructors in this process. These results show that the NP for the nursing students is a work methodology of the profession that needs to be implemented effectively in the practical reality for its teaching to turn effective and for the future professionals to be able to bring real contributions in the achievement of systematized actions trying to improve the assistance quality and the nursing actions. It is expected that this study could help bringing some strategies to facilitate the merging between theory and practice in teaching the NP and stimulate a discussion about the topic at the Nursing Schools where the research was held together with the coordinators, instructors and students

O trabalho do enfermeiro de um hospital pediátrico de ensino e o SUS: desafios a enfrentar

This study analyzes the point of view of nurses working at a pediatric teaching hospital on their work process within the scope of the Brazilian unified healthcare system SUS, in order to identify factors that interfere with its development and find out how work relations are taking place between nurses, other nursing professionals and the multidisciplinary staff. It is a descriptive and analytical study, qualitative in nature, which starts with a consideration of a nurse s current practices and moves on to reflect on a perspective of transformation aiming at rethinking their work process pursuant to the principles of SUS. In order to attain these objectives, we decided on using the focal group as a data-collecting technique, which took place from November to December 2005, by using as instruments a questionnaire for the characterization of the persons being researched and a discussion outline. Theoretical support has approached transformations in the world of work, placing it in the context of healthcare and nursing and has tried, specifically, to understand the work process of a nurse engaged in the production of health services. Therefore, the discourse analysis of participants, in the light of theoretical support, has evinced an ambiguity inasmuch as though identified as such in their work process, nurses are also fulfilling multiple functions in health services. Through this study it has also been possible to identify several factors that interfere with the work of these professionals, including poor working conditions and excessive hiring of high school graduate interns as an attempt to make up for a meager nursing workforce, as well as reveal the possibilities brought about by the SUS in retargeting its professional practice to interdisciplinarity and integrality

Qualidade de vida medida pelo "WHOQOL-bref": estudo comparativo de pacientes em hemodiálise e pós-transplante renal

Exploratory descriptive study, prospective with quantitative approach, performed in the nefrology outpatient service from the Onofre Lopes University Hospital (HUOL), Natal/RN, aiming to identify aspects that concern Quality of Life (QOL) on transplanted and hemodialysis patients, as measured by WHOQOL-bref and describe the aspects that differentiate QL between the two groups as measured by the same instrument. The population was of 62 renal patients in hemodialysis and 58 transplantd, with data collected from february to march 2006. The instrument used was WHOQOL-bref, translated to and validated for Portuguese by the multicentric group of the World Health Organization (WHO) in Brazil. The results show predominance of the masculine gender both in the post-transplant group (55,17%), as well as in the hemodialysis group (51,61%); the age strip of 28 to 43 prevailed, among which were 53,45% transplanted and 48,99% hemodialysis patients; 79,93% of the hemodialysis patients and 62,07% of the transplanted were provenient from ouside the capital of the state; from the hemodialysis population, 59,68% were married, while among the transplanted 48,28% were single; 58,06% of the hemodialisys patients had 1 to 3 children, while the majority of the transplanted, 44,83%, had no children; regarding scholarity level on both groups, there was a predominance of incomplete fundamental school, representing 62,9% of the hemodialysis patients and 46,6% of the transplanted; regarding work status, 98,39% of those in hemodialysis informed not to be working, and the same applied to the transplanted, with 75,86%; regarding treatment time, most patients of both populations were in the 1- to 4-year interval, of which were 62,9% of the hemodialisys patients and 53,45% of the transplanted. The analysis of WHOQOL-bref reliability through Crobach s Alpha coefficient had a value of 0,8816, demonstrating good internal consistency for the instrument. Regarding description of QOL tests, the average scores of the post-transplant were (Q-1) 18,14 e (Q-2) 18,69, and 12,3 (Q-1) and 11,29 (Q-2) for the group in hemodialisys. Regarding the aspects that differentiate QOL on the two groups observed through average scores from the Domains: Physical, 15,91 for the post-transplant group and 12,71 for the hemodialisys group; Psychological, 16,75 for the post-transplant group and 14,84 for the hemodialisys group; Social Relations, 17,79 on the post-transplant group and 16,58 on the hemodialisys group; Environment, 14,16 on the post-transplant group and 12,38 on the hemodialisys group. On every evaluated item, the post-transplant group achieved higher scores when compared to the hemodialisys group. The diference in QOL for both populations was significant on all items evaluated with a p<0,005

Concepções de policiais militares sobre cuidados com a saúde

A ausência de cuidados do homem com a saúde representa um fenômeno significativo, pois contribui para o aumento da morbidade e mortalidade masculina por causas evitáveis. Essa realidade torna-se mais relevante quando se trata do policial militar, devido às peculiaridades do seu processo de trabalho. Visto isso, considera-se que os cuidados de saúde adotados por policiais militares atrelam-se ao entendimento de que possuem sobre os agravos à saúde, o qual perpassa por concepções de gênero e da profissão. Isso levou ao seguinte questionamento: Como o policial militar concebe os cuidados com a saúde. Objetivou-se analisar concepções de policiais militares sobre cuidados com a saúde. Trata-se de um estudo exploratório e descritivo, com abordagem qualitativa, desenvolvido junto a um Batalhão Militar do Comando de Policiamento de Natal, Rio Grande do Norte, Brasil. A coleta de dados foi realizada no período de junho a julho de 2013. Essa etapa foi antecedida pela anuência do Comandante Geral da Polícia Militar do Rio Grande do Norte, sob a aprovação do Comitê de Ética em Pesquisa da Universidade Federal do Rio Grande do Norte, com o CAAE nº 15449713.7.0000.5537, e autorização formal dos entrevistados mediante a assinatura do Termo de Consentimento Livre e Esclarecido (TCLE), atendendo às exigências da Resolução 466/2012, do Conselho Nacional de Saúde, no que se refere à pesquisa com seres humanos. Participaram do estudo 21 policiais militares, do sexo masculino, que trabalhavam no policiamento ostensivo, não estavam de licença médica e apresentaram condições psicológicas e/ou físicas favoráveis para responder aos questionamentos. Os dados foram coletados por meio de entrevista semiestruturada mediante um roteiro constituído de duas partes: a primeira com questões sociodemográficas com vistas à caracterização dos participantes da pesquisa e a segunda com duas questões norteadoras relativas ao objeto de estudo. Os depoimentos foram tratados conforme o método de análise de conteúdo na modalidade de análise temática segundo Bardin. Desse processo, emergiram três categorias: hábitos de vida de policiais militares, repercussão do trabalho na saúde de policiais militares e atitudes de policiais militares em frente dos problemas de saúde. A análise dos dados foi subsidiada pelo referencial teórico do Modelo de Crenças em Saúde (Health Belief Model), de acordo com as variáveis vulnerabilidade e barreiras . Para respaldar a discussão dos resultados, buscou-se na literatura conhecimentos acerca da saúde do homem e do policial militar. Os resultados apontaram que os entrevistados procuram cuidar da saúde com práticas de exercícios físicos, alimentos saudáveis e preservação do sono. No entanto, vivenciam dores de coluna, ganho de peso, dificuldades para dormir, estresse e sofrimento psicológico. Diante disso, eles buscam apoio quando acometidos por agravos à saúde e reconhecem a necessidade de medidas de segurança durante o serviço. Portanto, notam a sua condição de vulnerabilidade em decorrência de seu ofício, porém enfrentam dificuldades na adoção de práticas preventivas de agravos a saúde. Mediante os resultados, faz-se necessário que o enfermeiro atuante junto a este público elabore, implemente e acompanhe estratégias de atenção a sua saúde

Estudo do comportamento no estado fresco e endurecido do concreto com incorporação de resíduo de corte de botão

This works aims at investigating the effects of adding waste from RCBP-polyester button manufacturing to Portland cement concrete, particularly regarding its consistency and mechanic strength. The RCBP used came from a button factory located in Parnamirim, RN, Brazil. The waste was added to the concrete on different ratios: 5 %, 10 %, 15 % and 20 % of the total cement mass. A sample of concrete without the RCBP was used as reference, 1:1,33:2,45:0,50. For the mechanic strength test four samples were tested with different ages (3, 7 and 28 days old) and mixtures. Furthermore, a Slump Test was also conducted in order to verify the concrete s consistency. A tendency to a reduction in the compression resistance was noticed for all samples. For the samples with 5 % and 10 %, there was also an increase in the traction resistance during inflexion, regarding the reference concrete. In the microstructural analysis, the RBCP was observed to show an irregular and porous surface, thus explaining the consistency decrease

Aplicação superficial de calcário em pomar de laranjeira pêra em produção

A citricultura paulista é a maior do mundo, sendo de extrema importância manejos que visem a aumentar e melhorar a produção de frutos. Com vistas a isso, foi instalado na EECB (Bebedouro-SP), em um Latossolo Vermelho distrófico típico, um experimento com a aplicação de cinco doses de calcário calcinado, em julho/99. Os efeitos no solo foram avaliados através de amostragens nas camadas de 0-10; 10-20; 20-40 e 40-60 cm, aos 6; 12; 18; 24; 30 e 36 meses. Através da utilização de modelos lineares, constatou-se que os efeitos da aplicação superficial de calcário no solo podem atingir até a camada de 20-40 cm, sendo a saturação por bases uma ótima característica indicadora da ação do corretivo. A máxima reação do calcário ocorreu entre 12 e 18 meses após a aplicação. O estado nutricional das plantas e a produção foram alterados, significativamente em função da aplicação superficial de calcário, sendo que melhores respostas da planta foram obtidas com saturação por bases de aproximadamente 50%.

Frações de zinco em solo arenoso e suas relações com disponibilidade para Cynodon spp cv. Tifton-85

Para avaliar um esquema de fracionamento de zinco em Argissolo arenoso e suas relações com a disponibilidade de Zn para Cynodon spp cv. Tifton-85, realizou-se um experimento em casa de vegetação, em esquema fatorial 5 x 2 x 2 (5 doses de Zn, 2 doses de calcário e 2 épocas de amostragem), em delineamento inteiramente casualizado, com três repetições. As doses de Zn foram de 0; 2,5; 5,0; 7,5 e 10 mg dm-3; metade dos vasos não recebeu calagem (V = 42 %) e metade recebeu a calagem com vistas em elevar o índice de saturação por bases a 70 %. As épocas de amostragem foram 30 e 150 dias após aplicação de Zn, respectivamente, antes do plantio e depois do 3º corte de Tifton-85. A aplicação de Zn resultou em aumento significativo do elemento nas frações: trocável, óxidos de Mn, matéria orgânica e óxidos de Fe. O Zn ligado aos óxidos de Mn aumentou significativamente com a calagem. Após 150 dias de experimentação, houve diminuição do Zn trocável, ligado aos óxidos de Mn, à matéria orgânica e aos óxidos de Fe, e aumento na fração residual. A distribuição de Zn nas frações do solo foi: residual > óxidos de Fe > óxidos de Mn > trocável > matéria orgânica. As relações entre as características estudadas mostraram que tanto o Zn-DTPA quanto o Zn trocável, ligado à M.O. e aos óxidos de Mn, foram eficientes para representar o Zn absorvido pela planta.

Caracterização de rizóbios indicados para produção de inoculantes por meio de sequenciamento parcial do 16S rRNA

O objetivo deste trabalho foi confrontar as sequências parciais do gene 16S rRNA de estirpes padrão de rizóbios com as de estirpes recomendadas para a produção de inoculantes no Brasil, com vistas à verificação da confiabilidade do sequenciamento parcial desse gene para a identificação rápida de estirpes. Foram realizados sequenciamentos através de reação em cadeia da polimerase (PCR) com iniciadores relativos à região codificadora do gene 16S rRNA entre as bactérias estudadas. Os resultados foram analisados pela consulta de similaridade de nucleotídeos aos do Basic Local Alignment Search Tool (Blastn) e por meio da interpretação de árvores filogenéticas geradas usando ferramentas de bioinformática. A classificação taxonômica das estirpes Semia recomendadas para inoculação de leguminosas com base em propriedades morfológicas e especificidade hospedeira não foi confirmada em todas as estirpes. A maioria das estirpes estudadas, consultadas no Blastn, é consistente com a classificação proposta pela construção de árvores filogenéticas das sequências destas estirpes, com base na similaridade pelo sequenciamento parcial do gene considerado.

Gestão dos resíduos sólidos das contruções prediais na cidade do Natal-RN

The present work has the objective of presenting an investigation about the quantification, classification and destination of the waste of construction and demolition (RCD) in the city of Natal - RN, focusing the aspects of the environmental impacts and the strategic importance of the environmental administration in the earnings of productivity of the companies. Of the environmental point of view the research intends to identify and to quantify the monthly and annual production of RCD in the city, as well as to know the places of deposition of those residues. To reach the objectives of the study, an exploratory and descriptive research was accomplished, using a questionnaire with closed subjects and an open one, applied in 25 entrepreneurs of the branch of the building site, being 21 builders and 4 entrepreneurs of collection companies and removal dumps. As form of analysis of the data, the descriptive analysis was used and of crossing. The production engineering considers important the insert of best production practices and administration of the product in the companies, with views to the increase of your competitiveness, productivity earnings and improvement of the environmental aspects with views to the consumer's satisfaction, in that case the buyer of immobile. The principal results of the investigation demonstrate that there was not great variability of answers with relationship to the interviewees opinion in what he refers to the environmental practices. In your majority the building site interviewees entrepreneurs evidenced the absence of the public power, particularly the city hall of Natal, in the control, fiscalization and creation of mechanisms for a correct destination of RCD, as well as for your reuse and recycle. On the other hand also it was evident that the recycle or the reuse of RCD on the part of the companies is a rare practice and a lot of times inexistent, although the entrepreneurs' of the building site section great majority recognizes that would have won of productivity with the correct and intensive use of such measures
