A pesar de todos los avances realizados en las últimas décadas en el conocimiento sobre numerosos aspectos del Síndrome Respiratorio Bovino (SRB), entre los que se encuentran los factores de riesgo, la etiopatogenia, las características de los agentes causales, el diagnóstico, la terapéutica o la profilaxis y sus efectos globales, el SRB continúa siendo la enfermedad de mayor impacto económico en el ganado vacuno de cebo. Además, parece que tanto su incidencia como las pérdidas que origina siguen estables en los cebaderos de todo el mundo desde hace varias décadas. Sus principales características indican que debemos considerar que es una enfermedad de difícil control dado su carácter multifactorial y con la que, por tanto, debemos acostumbrarnos a convivir aunque aspirando a minimizar tanto su incidencia, como la gravedad de sus consecuencias. Por otro lado, aunque existen muchas técnicas diagnósticas a nuestra disposición, aún no se puede decir que exista una técnica de referencia o “gold standard” para el diagnóstico del SRB, y mucho menos una técnica estandarizada para su diagnóstico precoz. Establecer y estandarizar protocolos para la detección de grupos de animales en riesgo y su monitorización más intensa en fases posteriores del cebo para reducir el consumo de antibióticos de uso preventivo o metafiláctico es de gran interés. Hasta ahora, este tipo de estrategias se han basado en la detección de evidencias de contacto con gérmenes patógenos pulmonares (principalmente análisis de serología). Sin embargo, no debemos olvidar que la identificación de un agente patógeno en ausencia de una lesión y/o signos clínicos atribuibles al mismo, tan sólo es indicativa de contacto previo (no de padecimiento de un proceso de enfermedad) y que, por otro lado, la mayoría de los agentes microbiológicos ligados al SRB son comensales habituales de las vías respiratorias altas. De modo que la identificación de un agente sólo prueba enfermedad si se diagnostica junto con los signos clínicos compatibles de enfermedad y la lesión...

Enquadramento: A parentalidade é um tema de saúde com muita relevância na sociedade atual, intervindo o seu exercício na promoção da saúde e bem-estar da criança. A parentalidade envolve acontecimentos stressantes, nomeadamente em situações de problemas de saúde e necessidades básicas e de resposta ao comportamento da criança, como é o caso do choro/birra e no momento de alimentação, procurando a maioria dos cuidadores responder ao problema de forma independente enquanto outros solicitam apoio dos profissionais de saúde. Objetivo: Identificar recomendações concretas, baseadas na evidência científica, de boas práticas e recomendações a transmitir aos pais para lidarem com o choro /birras e no momento da alimentação da criança. Métodos: Realizou-se uma revisão sistemática da literatura de estudos realizados nos idiomas português, inglês e espanhol, publicados entre 2009 e 2014, em bases de dados internacionais CINAHL® Plus with Full-Text, Nursing & Allied Health Collection, Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic Reviews (CDSR) e Database of Abstracts of Reviews of Effects (DARE), MedicLatina , MEDLINE, com recurso a diversos descritores e operadores booleanos e recorrendo a dois revisores que avaliaram a qualidade dos estudos metodológicos. Resultados: Após avaliação crítica, foram excluídos 50 estudos e incluídos 7, sendo um de grau de evidência A, dois de evidência B e 4 de evidência D. Os outcomes evidenciaram que para gestão da parentalidade o aconselhamento deve feito pelo profissional de referência, que se necessário deverá acompanhar os pais através de contacto telefónico e visita domiciliária sobretudo se mães inexperientes. Os profissionais devem ampliar os seus conhecimentos sobre as dúvidas e preocupações que os pais têm sobre a educação dos seus filhos consultando os espaços de discussão online. A etnia e nacionalidade das mães tem forte impacto sobre os métodos usados para acalmar o bebé, pelo que os cuidados devem ser culturalmente congruentes. Na abordagem do choro/ birras torna-se necessário conhecer o normal desenvolvimento da criança e em que contextos surgem para minimizá-las, sendo importante que os pais dêem à criança atenção positiva, instituindo rotinas. Para melhorar o momento da alimentação os pais devem reconhecer que até aos dois anos decorre a janela de oportunidade de aprendizagem de rotinas e de novos sabores, salientando-se a importância do ambiente de atenção e reciprocidade durante as refeições. Conclusão: Os enfermeiros devem procurar orientar a sua prática com base nas evidências científicas e tendo como base o estudo efectuado, salienta-se a promoção da parentalidade positiva como central para a abordagem dos comportamentos de choro/birra e no momento da alimentação da criança. Palavras – chaves: educação parental, enfermeiro, aleitamento materno, alimentação, birra, choro, relação pais-filhos.

As unidades de alimentação ininterruptas, UPS’s, desempenham na atualidade um papel fundamental na alimentação de cargas críticas nas instalações elétricas. Na cada vez mais premente necessidade de garantir qualidade e continuidade de energia levou a que este tipo de equipamentos se tenha desenvolvido e aperfeiçoado do ponto de vista tecnológico. A alimentação das instalações elétricas proveniente da rede de distribuição de energia contém ou está sujeita a micro interrupções, interrupções, sobretensões, conteúdo harmónico indesejável, não garantindo os níveis exigidos por alguns dos sistemas elétricos atuais colocando em causa a cadeia de valor de muitas empresas. O nível de disponibilidade e qualidade de potência está diretamente relacionado e produz efeitos diretos na continuidade das operações. Fatores como a produtividade, qualidade de produtos e serviços, capacidade concorrencial, segurança de bens e pessoas são imprescindíveis. Os sistemas de UPS’s de elevada potência com unidades de alimentação ligadas em paralelo garantindo redundância no fornecimento de energia às cargas constituem hoje a solução para o tipo de problemas referido. Contudo, a sua inserção nas instalações elétricas obriga a cuidados específicos, nomeadamente no que se refere ao regime de neutro da instalação, o qual condiciona de forma determinante a proteção de circuitos de distribuição e de pessoas. Em Portugal o regime de neutro adotado, de uma forma generalizada, regime de terras separadas (é o regime TT), no qual a proteção de pessoas é assegurada pela colocação de dispositivos de corrente residual diferencial. Solução que no caso das configurações de paralelos redundantes de UPS’s de elevada potência não garante um normal funcionamento destes sistemas concebidos para fundamentalmente funcionarem em regime TN (regime de Terra pelo Neutro). No presente trabalho apresenta-se no caso de estudo uma situação típica de instalação na qual se registam problemas de conflitos de neutro na saída de UPS’s que obrigam à alteração do tipo de dispositivo de proteção nas entradas das máquinas e circuito de bypass. São, ainda, apresentadas propostas de solução.

A Segurança Alimentar e Nutricional do trabalhador brasileiro é uma das formas de garantia de saúde e conseqüente aumento de produtividade refletido pelo compromisso do PAT Programa de Alimentação do Trabalhador que completou 30 anos em 2006. O objetivo do estudo é relacionar a variação de preços das commodities de alimentos presentes na refeição do trabalhador de acordo com o sistema normativo do PAT, identificando possíveis conseqüências negativas à Segurança Alimentar do Trabalhador no Brasil. A metodologia, por meio da análise de regressão múltipla, utiliza os dados de ICV Índice de Custo de Vida - de alimentação fora do domicílio como proxy a alimentação do trabalhador. Os resultados sugerem que os alimentos que apresentaram variação negativa com os tipos de refeições analisadas, como a carne suína e a soja, podem ser substituídos por outro valor nutricional semelhante como a carne bovina, o frango e o óleo de milho. Apenas a variação do preço do feijão foi seguida pelo aumento do preço do prato comercial, cuja alternativa é a mudança na maneira de oferecer a refeiç ão ao trabalhador, como os restaurantes por quilo. Diante do cenário exposto, há indícios de que a variação de preços dos alimentos no mercado de commodities teria pouca influência no preço final das refeições, mas a discussão em torno da futura escassez de oferta de alimentos devido ao aumento da população mundial e a mudança dos padrões alimentares com as sociedades urbanizadas insere o risco da SAN no contexto político e econômico da nutrição.(AU)

This research has vegan groups in the city of Natal-RN as interlocutors, although I also report to other research contexts, such as those located in the cities of Recife (Pernambuco State) and Campina Grande (Paraíba State). Moved by ethical principles based on animal rights, vegans refuse to consume any product with animal origin. To the extent that consumption habits can be considered powerful elements of identification, the relationship between consumption, food, identity, and politics is an important analytical key in the development of this work. As my main theoretical question, I follow the ways by which the vegan discourse (of abolitionist character) takes shape and materializes into actions, demonstrations and political mobilization. Therefore, I aim to present an ethnography of activities performed collectively by these individuals, such as those of a more ludic character (picnics, etc.) as well as those more politically oriented, especially protests and demonstrations in public places.

The recognition of the food as determinant and health-disease process etching requires new explanations and interventions of the food and nutrition policy action and demand health care model based on the completeness of the actions and focused on health promotion. This study, characterized as research-action of interventionist character, sought to develop strategies to support the transverse insertion of healthy eating promotion in professionals practices a core of support for the health of the family and a family health strategy Unit in the city of Natal, capital of Rio Grande do Norte, from the analysis of perceptions and work processes of these teams. Several methodological strategies were adopted: Dialectical Hermeneutical Circle, direct observation, reflective and Thematic Meetings Workshop "Rethinking the educational practices for promoting healthy eating". For data logging, search diaries - SD were used and moments. The analysis of procedural form occurred in conjunction with research participants, in constant movement of reflection-action-reflection, based on hermeneutics-dialectic. About the results, in relation to the promotion of health, showed the following insights: health promotion and disease prevention-related harms; health promotion related to quality of life and well-being, in its various dimensions; health promotion as a responsibility of the State; health promotion related to the actions of health education; health promotion as an expression of efficaciousness and accessibility to health services. Regarding healthy nutrition, predominated the perceptions relating to nutritional aspects. With regard to food and nutritional education - FNE, it was observed a predominance of perception of FNE as information, guidance and knowledge transfer for changes of dietary practices. As regards the working process, it was observed that among the actions for health promotion, educational activities predominate, such as lectures, conversations, groups that mostly occur in fragmentary form, without joint planning teams, varying according to the professionals and the moment of work in which they are carried out. The results pointed to the need for reorganization of the work processes, in the context of intra-and intersectoral coordination and the construction of new technologies, such as: Health project of the territory – HPT, Unique Therapeutic Project- UPT, Expanded Clinic and educational practices, Shared with active teaching and learning methodologies. From the results we believe that it is necessary to "thought reform", from changes in vocational training and strengthening of the permanent education spaces, whereas the complexity that involves feeding, food and nutrition education and health promotion. The reformation of thought must be articulate and closely tied to the production of knowledge and practices that encourage intersectoral approach, the transversality, dialogue and democratic and supportive attitude, based on the collective construction of know-how. We hope that this study can contribute with reflections and initiatives that encourage building practices that promote healthy eating in primary health care, in terms of completeness of the care and the attainment of food security and nutrition.

The Food and Nutrition Units (FNU) are designed to produce food for healthy and/or sick communities and need to be done in a way to ensure the quality of foodstuffs that were produced. In these units, in the working environment, in general, there is excessive noise, heat and physical condition with many adaptations, presence of obstacles, inadequate flows, as well as the ways of the working organization may represent risks for workers health and lead to errors during production and/or distribution of food. The main goal of this study was to analyse the working processes in the Food Production Unit of the university’s hospital and identify the workers' health risk factors, using for this the knowledge of ergonomics, specifically the method of Ergonomic Work Analysis (EWA). After this analysis it was possible to develop proposals that will bring improvements to the working conditions, minimizing health risk factors during the process of meals production. It’s crucial to reassert this method considers the work activity performed in real time and highlights the importance of listening and the engagement of the workers in the changing process. It is a descriptive research with a qualitative approach. In the field research were collected demographics data, employment characteristics of the individuals (age, education, stocking sector, the total length of service and length of service in the industry) and data related to their usual work (task analysis, activity analysis and Analysis of the working environment) in the FNU. The instruments that were used in this study were document analysis, global and systematic observations and semi structured interviews in order to identify the main complaints related to those activities developed by them. The study was based on data for the analysis of Bardin, 2011, so the documents have been selected and including those that treat issues related to risks to workers' health were selected. The result of semi-structured interviews, global and systematic observations took place a confrontation of this material to the theoretical framework, held the inference and the interpretation of results the light of the knowledge of ergonomics and legislation. Issues related to the risks and the perception of workers has crafted a table showing the frequency of responses to the physical, chemical and biological and even the risk of accidents and was made a descriptive analysis. The results of this analysis indicated that the unit in question presents several problems ambience of jobs, both in terms of physical structure, but also in the organization of work. Non-conformities that leads to a favourable environment to the development of disease and injury hazards and compromising the quality of food produced. It is necessary to comply with legislation and that short, medium and long-term measures are taken to ensure the physical integrity of workers and improve the working environment.

This study analyzed the Worker’s Healthy Eating Program in Rio Grande do Norte state (RN) to assess its possible impact on the nutritional status of the workers benefitted. To that end, we conducted a cross-sectional observational prospective study based on a multistage stratified random sample comparing 26 small and medium-sized companies from the Manufacturing Sector (textiles, food and beverages, and nonmetallic minerals) of RN, divided into two equal groups (WFP and Non WFP). Interviews were conducted at each company by trained interviewers from Tuesday to Saturday between September and December 2014. Data were collected on the company (characterization and information regarding the program’s desired results) and workers (personal and professional information, anthropometrics, health, lifestyle and food consumed the previous day). Population estimates were calculated for RN on the characteristics of workers and the study variables. The main variable was BMI. The secondary variables were waist circumference (WC), nutritional diagnosis, calorie intake, blood pressure, metabolic variables and lifestyle indicators. The statistical method used was hierarchical mixed effects linear regression for interval variables and hierarchical mixed effects logistic regression for binary variables. The variables measured in ordinal scales were analyzed by ordinal logistic regression adjusted for correlated variables, adopting robust standard errors. The results for interval variables are presented as point estimates and their 95% confidence intervals; and as odds-ratios and their 95% confidence intervals for binary variables. The Fisher’s exact and Student’s t-tests were used for simple comparisons between proportions and means, respectively. Differences were considered statistically significant at p<0.05. A total of 1069 workers were interviewed, of which 541 were from the WFP group and 528 from the Non WFP group. Subjects were predominantly males and average age was 34.5 years. Significant intergroup differences were observed for schooling level, income above 1 MW (minimum wage) and specific training for their position at the company. The results indicated a significant difference between the BMI of workers benefitted, which was on average 0.989 kg/m2 higher than the BMI of workers from the Non WFP group (p=0.002); and between the WC, with the waist circumference of WFP group workers an average of 1.528 cm larger (p<0.05). Higher prevalence of overweight and obesity (p<0.001) and cardiovascular risk (p=0.038) were recorded in the WFP group. Tests on the possible effect of the WFP on health (blood pressure and metabolic indicators) and lifestyle indicators (smoking, alcohol consumption and exercise) were not significant. With respect to worker’s diets, differences were significant for consumption of saturated fat (lunch and daily intake), salt (lunch, other meals and daily intake) and proteins (other meals and daily intake), with higher consumption of these nutrients in the WFP group. The study showed a possible positive impact of the WFP on nutritional status (BMI and WC) among the workers benefitted. No possible effects of the program were observed for the lifestyle indicators studied. Workers benefitted consumed less salt, saturated fat and protein. The relevance of the WFP is recognized for this portion of society and it is understood that, if the program can reach and impact those involved, the development of educational initiatives aimed at nutritional and food safety may also exert a positive influence.

The Benzylpenicillin (PENG) have been as the active ingredient in veterinary medicinal products, to increase productivity, due to its therapeutic properties. However, one of unfortunate quality and used indiscriminately, resulting in residues in foods exposed to human consumption, especially in milk that is essential to the diet of children and the ageing. Thus, it is indispensable to develop new methods able to detect this waste food, at levels that are toxic to human health, in order to contribute to the food security of consumers and collaborate with regulatory agencies in an efficient inspection. In this work, were developed methods for the quality control of veterinary drugs based on Benzylpenicillin (PENG) that are used in livestock production. Additionally, were validated methodologies for identifying and quantifying the antibiotic residues in milk bovine and caprine. For this, the analytical control was performed two steps. At first, the groups of samples of medicinal products I, II, III, IV and V, individually, were characterized by medium infrared spectroscopy (4000 – 600 cm-1). Besides, 37 samples, distributed in these groups, were analyzed by spectroscopy in the ultraviolet and near infrared region (UV VIS NIR) and Ultra Fast Liquid Chromatograph coupled to linear arrangement photodiodes (UFLC-DAD). The results of the characterization indicated similarities, between PENG and reference standard samples, primarily in regions of 1818 to 1724 cm-1 of ν C=O that shows primary amides features of PENG. The method by UFLC-DAD presented R on 0.9991. LOD of 7.384 × 10-4 μg mL-1. LOQ of 2.049 × 10-3 μg mL-1. The analysis shows that 62.16% the samples presented purity ≥ 81.21%. The method by spectroscopy in the UV VIS NIR presented medium error ≤ 8 – 12% between the reference and experimental criteria, indicating is a secure choice for rapid determination of PENG. In the second stage, was acquiring a method for the extraction and isolation of PENG by the addition of buffer McIlvaine, used for precipitation of proteins total, at pH 4.0. The results showed excellent recovery values PENG, being close to 92.05% of samples of bovine milk (method 1). While samples of milk goats (method 2) the recovery of PENG were 95.83%. The methods for UFLC-DAD have been validated in accordance with the maximum residue limit (LMR) of 4 μg Kg-1 standardized by CAC/GL16. Validation of the method 1 indicated R by 0.9975. LOD of 7.246 × 10-4 μg mL-1. LOQ de 2.196 × 10-3 μg mL-1. The application of the method 1 showed that 12% the samples presented concentration of residues of PENG > LMR. The method 2 indicated R by 0.9995. LOD 8.251 × 10-4 μg mL-1. LOQ de 2.5270 × 10-3 μg mL-1. The application of the method showed that 15% of the samples were above the tolerable. The comparative analysis between the methods pointed better validation for LCP samples, because the reduction of the matrix effect, on this account the tcalculs < ttable, caused by the increase of recovery of the PENG. In this mode, all the operations developed to deliver simplicity, speed, selectivity, reduced analysis time and reagent use and toxic solvents, particularly if compared to the established methodologies.

This thesis proposes the adoption of a practical and philosophic approach to the discussion about what should be a healthy food, in view of the actual problems concerning this subject (from famine to obesity), which affect food and nutritional security and constitute target of many official policies. In order to handle this task, this work resorts to ethic, pedagogical and anthropological concepts inherent to Immanuel Kant’s philosophy, as valuable contributions to the practice of the professional nutritionist committed to the support and accomplishment of the human right to adequate nutrition (DHAA). Under this assumption, it intends to surpass the prevailing idea inside the social programs and policies favoring the utilitarian argument. It considers rather that a healthy food is also a duty of virtue, according to the Kantian duties to one-self. The liberation of transgenic seeds in Brazil comes up as an example of the violation of the right to food security and affects it negatively, resulting from the conflict between politics and moral faced by the Brazilian government. This paper concludes that DHAA realization requires not only a committed state, but also committed citizens and suggests that Kant’s philosophy should offer important contributions to supporting the practice of the professional nutritionist, awarding him the necessary information about this matter.
