REDUCTION IN THE CONSUMPTION OF EFFLUENT GENERATED IN NILE TILAPIA SLAUGHTERHOUSE THROUGH THE CONCEPTS IMPLANTATION OF CLEANER PRODUCTION (CP)

the nourishing industry is a segment that makes use of high water consumption due to necessity of the hygienic cleaning of the establishments and the maintenance of the good quality of the food. It enters the nourishing industries with bigger water consumption we have the fishery industry which generates effluent around 5.4 m(3). t(-1) of processed fish. This work had as objective the reduction in the water consumption of the processing of Nile tilapia through the implantation of P+L techniques, for had been in such a way carried through hydraulical alterations in the filleting tables aiming at the minimum possible water consumption for two methods of filleting, eviscerated and not eviscerated, as well as the comment of the alterations in the generated quality of the effluent one. In the present study, the reduction in the water consumption in the filleting process corresponded 98.16% for method EV considering an average time of processing of 3 hours for 32.99 kg of fish, and for method NEV the reduction was of 97.97% with average time of processing of 2.1 hours for 34.96 kg of fish, thus demonstrating that the P+L techniques are efficient for the reduction of the water consumption.34228929

Psychological stress factors and salivary cortisol in nursing students throughout their training

OBJECTIVE: to analyze psychological stress factors and salivary cortisol concentration in nursing undergraduates throughout their training. METHOD: a cross-sectional, analytical, and comparative study carried out in an evening course using a sociodemographic questionnaire, an Instrument to Assess Stress in Nursing Students, and salivary cortisol analysis. The study included descriptive and comparative analyses and a multiple linear regression model. RESULTS: 187 participants answered the questionnaires, and 129 had their cortisol quantified. The domains Practical Activities Execution, Professional Communication, and Professional Training represented the stress factors with the highest mean values for 3rd, 4th, and 5th-year students compared to 1st and 2nd year. For the 5th year, it was the domains Professional Communication and Professional Training compared to the 3rd year and Environment compared to the 1st and 3rd year. A significant result was obtained between the times of cortisol collections for males (p < 0.0001), females (p < 0.0001), and for 1st (p = 0.0319) 2nd (p = 0.0245), and 5th (p < 0.0001) years. CONCLUSION: Students in years 3 through 5 had higher exposure to stressors, and there were adjustments in cortisol production rhythmicity for students in years 1, 2, and 5

Fractal analysis of Xylella fastidiosa biofilm formation

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)We have investigated the growth process of Xylella fastidiosa biofilms inoculated on a glass. The size and the distance between biofilms were analyzed by optical images; a fractal analysis was carried out using scaling concepts and atomic force microscopy images. We observed that different biofilms show similar fractal characteristics, although morphological variations can be identified for different biofilm stages. Two types of structural patterns are suggested from the observed fractal dimensions D(f). In the initial and final stages of biofilm formation, D(f) is 2.73 + 0.06 and 2.68 + 0.06, respectively, while in the maturation stage, D(f) = 2.57 + 0.08. These values suggest that the biofilm growth can be understood as an Eden model in the former case, while diffusion-limited aggregation (DLA) seems to dominate the maturation stage. Changes in the correlation length parallel to the surface were also observed; these results were correlated with the biofilm matrix formation, which can hinder nutrient diffusion and thus create conditions to drive DLA growth.

A inclusão da equipe de saúde bucal na Estratégia Saúde da Família: entraves, avanços e desafios

O objetivo deste artigo é discutir a inclusão da saúde bucal na Estratégia Saúde da Família, em cidades de uma microrregião do sudeste do Brasil, sob a perspectiva dos recursos humanos. Foram aplicados questionários aos integrantes do serviço de saúde bucal: dentistas, auxiliares e gestores. O instrumento considerou três dimensões: como e porque se adotou o novo modelo, como o serviço está se reorganizando e que avanços foram percebidos pelos profissionais. O motivo mais mencionado pelos gestores, para inclusão da Saúde Bucal foi a possibilidade de mudança do modelo tecno-assistencial. Dentistas e auxiliares quando questionados sobre sua motivação, também consideraram prioritariamente a possibilidade de mudança na prática. Observou-se ainda que existem nós críticos na contratação e capacitação de recursos humanos para atuar na equipe de saúde bucal e na integração entre os profissionais de saúde. Mas o acesso está melhor, seja pela organização efetuada, seja pela expansão de equipes. Os municípios da microrregião ainda enfrentam percalços para que o funcionamento do serviço de saúde bucal, após a Saúde da Família, apresente avanços reais nas práticas de atenção. Porém, os avanços existem e estes devem ser reforçados, para consolidação do sistema de saúde e melhoria na qualidade de vida da população

Health services performance for TB treatment in Brazil: a cross-sectional study

<p>Abstract</p> <p>Background</p> <p>Researches to evaluate Primary Health Care performance in TB control in Brazil show that different cities aggregate local specificities in the dynamics of coping with the disease. This study aims to evaluate health services' performance in TB treatment in cities across different Brazilian regions.</p> <p>Methods</p> <p>This cross-sectional study was conducted in five cities that are considered priorities for TB control in Brazil: Itaboraí (ITA), Ribeirão Preto (RP) and São José do Rio Preto (SJRP) in the Southeast; Campina Grande (CG) and Feira de Santana (FS) in the Northeast. Data were collected through interviews with 514 TB patients under treatment in 2007, using the <it>Primary Care Assessment Tool </it>adapted for TB care in Brazil. Indicators were constructed based on the mean response scores (Likert scale) and compared among the study sites.</p> <p>Results</p> <p>"Access to treatment" was evaluated as satisfactory in the Southeast and regular in the Northeast, which displayed poor results on 'home visits' and 'distance between treatment site and patient's house'. "Bond" was assessed as satisfactory in all cities, with a slightly better performance in RP and SJRP. "Range of services" was rated as regular, with better performance of southeastern cities. 'Health education', 'DOT' and 'food vouchers' were less offered in the Northeast. "Coordination" was evaluated as satisfactory in all cities. "Family focus" was evaluated as satisfactory in RP and SJRP, and regular in the others. 'Professional asking patient's family about other health problems' was evaluated as unsatisfactory, except in RP.</p> <p>Conclusions</p> <p>Two types of obstacles are faced for health service performance in TB treatment in the cities under analysis, mainly in the Northeast. The first is structural and derives from difficulties to access health services and actions. The second is organizational and derives from the way health technologies and services are distributed and integrated. Incentives to improve care organization and management practices, aimed at the integration of primary, secondary and tertiary services, can contribute towards a better performance of health services in TB treatment.</p

A perspectiva territorial da inovação em saúde: a necessidade de um novo enfoque

A inovação ganha um campo de estudo privilegiado na saúde, dado que esta é responsável por parcela importante do investimento nacional em pesquisa e desenvolvimento e possui uma base industrial e de serviços que articula tecnologias portadoras de futuro. Assim, estreita-se o relacionamento entre saúde e desenvolvimento também em função do protagonismo da saúde na geração de inovação. A despeito disso, persiste a fragilidade da base produtiva da saúde, prejudicando tanto a prestação universal de serviços em saúde quanto uma inserção competitiva internacional. Este artigo, que utiliza o arcabouço teórico da Economia Política e dos sistemas de inovação, teve como objetivo identificar variáveis em espaços subnacionais que influenciam a dinâmica de geração de inovação em saúde, a partir de uma abordagem teórica que considera que a inovação é um processo contextualizado e social. Parte do pressuposto de que a fragilidade da base produtiva em saúde persistirá se novas variáveis envolvidas na dinâmica de inovação não forem consideradas.La innovación gana un campo de estudio privilegiado en la salud, dado que ésta es responsable por fracción importante de la inversión nacional en investigación y desarrollo y posee una base industrial y de servicios que articula tecnologías portadoras de futuro.

Parte de la suposición que la fragilidad de la base productiva en salud persistirá si nuevas variables envueltas en la dinámica de innovación no llegan a ser consideradas.Innovation plays an increasingly important role in health care, partly because it is responsible for a significant share of national investment in research and development, and partly because of its industrial and service provision base, which provides a conduit to future technology. The relationship between health care and development is also strengthened as a result of the leading role of health care in generating innovation. Nevertheless, Brazil's health care production base is persistently weak, hindering both universal provision of health care services and international competitiveness. This article, based on the theoretical framework of Political Economy and innovation systems, has sought to identify variables in subnational contexts that influence the dynamic of innovation generation in health care. To this end, the theoretical approach used lies on the assumption that innovation is a contextualized social process and that the production base in healthcare will remain weak if new variables involved in the dynamic of innovation are not taken into account

Contextual and individual factors associated with dental services utilisation by Brazilian adults: A multilevel analysis

BACKGROUND: Inequalities in the utilisation of dental services in Brazil are remarkable. The aim of this study was to evaluate the association of contextual and individual factors with the utilisation of dental services by Brazilian adults using the Andersen's behavioural model. METHODS: Individual-level data from 27,017 adults residents in the State capitals who were interviewed in the 2013 Brazilian National Health Survey were pooled with contextual city-level data. The outcomes were non-utilisation of dental services and last dental visit over 12 months ago. Individual predisposing variables were age, sex, race/skin colour, schooling and social network. Individual enabling variables included income, health insurance and registration in primary health care. Individual need variables were self-perceived dental health and self-reported missing teeth. Multilevel logistic regression models were performed to estimate odds ratio (OR) and 95% confidence intervals (95% CIs) of the association of contextual and individual predisposing, enabling and need-related variables with dental services outcomes. RESULTS: Predisposing (OR = 0.89; 95% CI 0.81-0.97) and enabling (OR = 0.90; 95% CI 0.85-0.96) contextual factors were associated with non-utilisation of dental services. Individual predisposing (sex, race/skin colour, schooling), enabling (income, health insurance) and need (self-perceived oral health, missing teeth) were associated with non-utilisation of dental services and last dental visit over 12 months ago. The latter was also associated with other individual predisposing (age, social network) and need (eating difficulties due to oral problems) characteristics. CONCLUSIONS: Individual and contextual determinants influenced dental services utilisation in Brazilian adults. These factors should be on the policy agenda and considered in the organisation of health services aiming to reduce oral health inequalities related to access and utilisation of dental services
