Resumo Este estudo analisa a estruturação da Rede de Atenção à Saúde nas regiões de saúde do estado de Mato Grosso, considerando as ações planejadas nos instrumentos de gestão do governo do estado e da Secretaria de Estado de Saúde (SES), nos anos de 2012 a 2017, em conformidade com as diretrizes da Portaria MS/GM nº 4.279, de 30 de dezembro de 2010, que orienta o processo de conformação das redes de atenção à saúde no âmbito do Sistema Único de Saúde (SUS). Trata-se de estudo qualitativo, de natureza exploratório-descritiva, do tipo documental, que analisou os documentos públicos referentes ao planejamento do governo na especificidade do setor de saúde, o que inclui o Plano Plurianual, o Plano Estadual de Saúde e o Plano Estratégico da SES. Os achados do estudo mostram que, embora algumas ações/atividades relacionadas às diretrizes da portaria estivessem contempladas nos documentos pesquisados, ainda não foram suficientes para o estabelecimento de uma rede de atenção regionalizada de qualidade e para o fortalecimento da Atenção Primária à Saúde (APS) com capacidade de ser coordenadora do cuidado e ordenadora da rede no estado de Mato Grosso.

Abstract This study analyzes the structuring of the Health Care Network in the health regions of the state of Mato Grosso, considering the actions planned in the management instruments of the State government and the State Department of Health (SES), in the years of 2012 to 2017, in accordance with the guidelines of Ordinance MS/GM No 4.279, of December 30, 2010, which guides the process of conformation of Health Care Networks within the scope of the Brazilian National Health System (SUS). This is a qualitative, exploratory-descriptive study, of documentary type, which analyzed the public documents related to government planning on the specificity of the health sector, which includes the Pluriannual Plan, the State Health Plan and the Strategic Plan of the SES. The findings of the study show that, although some actions/activities related to the guidelines of the Ordinance were included in the researched documents, they were not yet sufficient for establishing a quality regionalized care network and for strengthening the Primary Health Care (PHC) with the capacity to coordinate care and order the network in the state of Mato Grosso.

RESUMO As restaurações dentárias que são realizadas com resinas compostas apresentam aspecto estético muito satisfatório, com coloração próxima à do dente e propriedades mecânicas aceitáveis. O grande desafio destas resinas é que tenham o mesmo, ou semelhante, desempenho mecânico que o dente original. O presente trabalho foi desenvolvido com o objetivo de avaliar as partículas inorgânicas do composto Al2O3-0,5B2O3-SiO2, produzidas pela técnica de spray pirólise (USP) para aplicação em resinas compostas dentárias. A síntese das partículas foi realizada empregando o método sol-gel, com os precursores nitrato de alumínio, ácido bórico e tetraetilortosilicato TEOS com pH da solução de 1,5. A fim de verificar as propriedades das partículas realizou-se caraterização físico-química pelo método de adsorção e dessorção de nitrogênio via BET, análise por MEV, FTIR, DRX, DTA-TGA, RMN e ensaio mecânico de tração. As imagens obtidas por MEV indicaram que as partículas eram esféricas de granulometria média de 1,26 ± 0,04 µm, sendo classificadas como microhíbridas. Pelos difratogramas observou-se característica amorfa, confirmando que o método de síntese aplicado é eficiente para a produção de materiais vítreos. Os testes com resina composta experimental apresentaram taxa de polimerização aceitável (16 e 9%), mas baixa resistência à compressão mecânica: entre 9,55 e 13,27 MPa.

ABSTRACT Dental restorations that are performed with composite resins present a very satisfactory aesthetic appearance, with a color close to that of the tooth and acceptable mechanical properties. The great challenge of these resins is that they have the same, or similar, mechanical performance as the original tooth. The present work was developed with the objective of evaluating the inorganic particles of the compound Al2O3-0,5B2O3-SiO2, produced by spray pyrolysis (USP) for application in dental composite resins. The synthesis of the particles was carried out using the sol-gel method, with the precursors aluminum nitrate, boric acid and TEOS tetraethylorthosilicate with a pH of 1.5. In order to verify the properties of the particles, physicochemical characterization was carried out using the nitrogen adsorption and desorption method via BET, analysis by SEM, FTIR, XRD, DTA-TGA, NMR and mechanical tensile testing. The images obtained by SEM indicated that the particles were spherical with a mean granulometry of 1.26 ± 0.04 µm, being classified as microhybrid. From the diffractograms, an amorphous characteristic was observed, confirming that the applied synthesis method is efficient for the production of glassy materials. Tests with experimental composite resin showed an acceptable polymerization rate (16 and 9%), but low mechanical compressive strength: between 9.55 and 13.27 MPa.

Abstract Introduction The use of hydroxychloroquine and chloroquine is formally indicated in cases of chronic autoimmune diseases. However, the use of these medications has already been associated with possible transitory or definitive alterations in hearing function and/or vestibular function in humans, when administrated in the short and long terms. Objective To describe, through a literature analysis, the functional vestibular and/or hearing alterations, caused by the use of hydroxychloroquine and chloroquine in youths and adults. Data Synthesis In total, 2,481 studies were identified in the initial search: out of these 32 were selected for a full-text reading, and 9 were selected after the exclusion of those which did not meet the eligibility criteria. Of these, four articles pointed to the presence of vestibular and auditory-associated alterations, three indicated only auditory pathologies, and two, vestibular disorders. Regarding the auditory alterations, tinnitus was the most frequent symptom, and bilateral sensorineural hearing loss was described in most studies, varying in degree from mild to severe. As for the vestibular alterations, vertigo was the most reported symptom. Conclusion Knowledge of the auditory and vestibular effects after the use of these substances can help in the decision regarding the best treatment, enabling the consideration of other available therapies for patients at risk of suffering those alterations, reducing the risk of auditory and vestibular disorders.

ABSTRACT Most studies on genomic selection in plant breeding compare different statistical methods of univariate approach. However, multi-trait methodologies should be considered since they allow the simultaneous selection of superior genotypes in several economic traits. Here, the aims were to compare the selection accuracy and efficiency of the multivariate partial least square (MPLS) method compared with random regression best linear unbiased predictor (rrBLUP), Bayesian Lasso (Blasso) and univariate partial least square (UPLS) and to develop genomic selection indexes efficient for superior genotypes identification in plant breeding. Ten F2 populations with 800 individuals were simulated, considering four traits with different heritabilities. Genomic selection analyses using rrBLUP, Blasso, UPLS, and MPLS were conducted. Four genomic selection indexes were elaborated by the sum of the marker effects obtained for each trait, weighted by the respective residual variance. Multi-trait indexes were developed based on the assumptions of each methodology mentioned (rrBLUP, Blasso, UPLS, and MPLS), and were denominated I-rrBLUP, I-Blasso, I-UPLS, and I-MPLS. Processing time, selective accuracy, selection gains, and selection coincidence were used to compare the methods and the selection indexes proposed. The MPLS method had similar results compared to UPLS method for the low heritability traits and was less efficient than the rrBLUP and Blasso. The genome selection indexes provided the highest total genetic gains. The I-rrBLUP and I-MPLS indexes stood out for high efficiency in selecting superior genotypes in the shortest processing time. Results suggest that the genomic selection indexes proposed in this study may be promising for plant breeding programs.

RESUMO A Caatinga, bioma exclusivamente brasileiro vem sofrendo elevada ação antrópica, o que interfere diretamente na qualidade de seu solo. Para avaliar e acompanhar a qualidade do solo vem-se utilizando indicadores químicos e biológicos, com a determinação da atividade enzimática, ganhando destaque. Neste sentido, objetivou-se avaliar a atividade enzimática de solos do bioma Caatinga em áreas preservadas e antropizadas, pertencentes ao Parque Nacional do Catimbau, situado em Pernambuco, Brasil, nos dois períodos do ano (chuvoso e seco), por três anos consecutivos, 2014, 2015 e 2016. Foram avaliadas as atividades enzimáticas de β-glicosidase, urease, arilsulfatase, fosfatase ácida e alcalina de solos. A ação antrópica proporcionou redução das atividades enzimáticas de β-glicosidase, urease e arilsulfatase. Entre os períodos do ano, o seco apresentou menores valores de atividade enzimática de β-glicosidase, urease e arilsulfatase. Entre os anos de avaliação, ao correlacionar a precipitação acumulada e a atividade enzimática, as maiores correlações foram observadas na área preservada em ambos períodos do ano. Comprovou-se a fragilidade dos solos da Caatinga sob a ação antrópica em ambas as estações dos períodos do ano, ao longo do tempo. A antropização crescente de áreas do Parque Nacional do Catimbau apresenta efeito direto na qualidade do solo, afeta seu equilíbrio ecológico, causando a sua degradação e redução de sua qualidade. Tornam-se necessárias medidas urgentes de fiscalização adequada para garantir a sua preservação ambiental.

ABSTRACT The Caatinga is an exclusively Brazilian biome that has been under high anthropogenic action, which directly interferes in the quality of its soil. In order to evaluate and monitor the quality of the soil, chemical and biological indicators are used, with the determination of the enzymatic activity gaining prominence. The objective of this study was to evaluate the enzymatic activity of soils of the Caatinga biome in preserved and anthropized areas belonging to the Catimbau National Park, located in Pernambuco, Brazil, during the two periods of the year (rainy and dry), for three consecutive years, 2014, 2015 and 2016. Enzymatic activities of β-glucosidase, urease, arylsulfatase, and acid and alkaline phosphatase in the soil were evaluated. Anthropic action caused reduction in the enzymatic activities of β-glucosidase, arylsulfatase and urease. Regarding the periods of the year, the dry one showed smaller values of enzymatic activity of β-glucosidase, arylsulfatase and urease. Among the evaluation years, when correlating accumulated precipitation and enzymatic activity, the highest correlations were observed in the preserved area in both periods of the year. The fragility of Caatinga soils under anthropic action was observed in both periods of the year, over time. The increasing anthropization of areas of the Catimbau National Park has a direct effect on soil quality, affects its ecological balance, causing degradation and reduction of its quality. Appropriate enforcement measures are urgently needed to ensure their environmental preservation.

RESUMO Sob perspectiva do uso das ramas de batata-doce para a alimentação animal, há carência de informações da influência desta ação sobre a qualidade do feno. Logo, objetivou-se estudar a associação dos atributos de produtividade da batata-doce com características químicas-bromatológicas do feno. Foram avaliados dez clones de batata-doce, conduzidos em blocos ao acaso com cinco repetições. Determinou-se as produtividades de massa verde e seca, teor de matéria seca e a relação folha e haste das ramas, a produtividade total e comercial de raízes, e, características químico-bromatológicas dos fenos a partir das ramas. Estimou-se a correlação fenotípica e a análise de trilha entre as características. A seleção para a maior produtividade de ramas e de raízes comerciais pode proporcionar o aumento no feno da proteína bruta, fibra de detergente neutro e ácido e açúcares solúveis totais. Porém, a seleção para a maior produtividade de raízes tem efeito negativo no teor de amido do feno, merecendo atenção especial do melhorista.

ABSTRACT From the perspective of the use of sweet potato branches for animal feed, there is a lack of information on the influence of this action on hay quality. Therefore, the objective was to study the association of sweet potato yield attributes with chemical-bromatological characteristics of hay. Ten sweet potato clones were evaluated, conducted in randomized blocks with five replications. Green and dry mass yield, dry mass content, leaf and stem ratio, total and commercial root yield, and chemical and bromatological characteristics of hay from the branches were determined. Phenotypic correlation and trial analysis between characteristics were estimated. Selection for the highest yield of roots and commercial roots may provide increased hay of crude protein, neutral detergent fiber and acid and total soluble sugars. However, selection for the highest root yield has a negative effect on the starch content of hay and deserves special attention from the breeder.

To increase yield, breeding programs must search for innovative and efficient methodologies for the development and selection of superior genotypes. Therefore, this study aimed to compare the single- and multiple-trait best linear unbiased prediction (BLUP) in genetic selection of parents and hybrids of grain sorghum. For this, an experiment conducted in alpha-lattice design with two replications was used. Flowering time (FT), plant height (PH), and grain yield (GY) were evaluated in 502 grain sorghum hybrids obtained by the cross of ten restorer lines and 54 male-sterile lines. Variance components were estimated via restricted maximum likelihood (REML). Significant effects of restorer lines, of male-sterile lines, and of specific combining ability were detected by the likelihood ratio test (LRT). The estimates of variance components, genetic parameters, and correlations were similar when obtained via single- and multiple trait BLUP. Considering hybrids, the multiple-trait BLUP resulted in slightly higher predicted selection gain for the three evaluated traits and, therefore, can be efficiently applied in the genetic selection of grain sorghum.

Para incrementar el rendimiento, los programas de mejoramiento deben buscar metodologías innovadoras y eficientes para el desarrollo y la selección de genotipos superiores. De esta forma, este estudio tuvo como objetivo comparar la mejor predicción lineal no viciada (BLUP) mono y múltiple característica, en la selección genética de parentales e híbridos de sorgo granelero. Para esto, fue usado un experimento con diseño alfa latice con dos repeticiones. Se evaluó el tiempo de floración (FT), la altura de planta (AP) y el rendimiento de granos (GY) en 502 híbridos de sorgo, obtenidos por el cruzamiento entre diez líneas restauradoras y 54 líneas macho estériles. Los componentes de varianza se estimaron mediante el método de máxima verosimilitud restringida (REML). Observamos que varias veces el BLUP múltiple característica da como resultado estimaciones de correlación genética más precisas. En este trabajo, se encontraron mayores correlaciones entre FT y GY a través de BLUP múltiple característica. Estos resultados llevaron a mayores ganancias genéticas para la selección de híbridos en comparación con BLUP mono característica.

Abstract Paprika oleoresin was co-crystallized to formulate a natural and hydrophilic dye for use in food applications. The color stabilities of the co-crystallized and free oleoresins were evaluated at different temperatures (25 and 35 °C, 70% RH) and light exposures (light 70 watts and dark, 25 °C, 70% RH). Co-crystallization from supersaturated sucrose syrup (S = 1.32) was found to be optimum for the formation of sugar agglomerates in a few minutes, with the paprika oleoresin entrapped inside. With time, decreases in the values of the a* parameter and the β-carotene content were observed with increasing temperature and with the incidence of light. The color degradation kinetics were dependent on both factors. The loss of color was greater for the free oleoresin as compared to the co-crystallized, suggesting that the co-crystallization process improves oleoresin retention in the sugar matrix, making it less susceptible to losses due to color degradation.

RESUMO O objetivo deste trabalho foi caracterizar o crescimento da planta e determinar a melhor época de colheita da batata-doce, considerando raízes e parte aérea (ramas). O trabalho foi realizado no campus JK da Universidade Federal dos Vales do Jequitinhonha e Mucuri, em Diamantina-MG. O delineamento experimental foi blocos ao acaso, com quatro repetições. Foram realizadas doze coletas consecutivas de três plantas centrais da parcela, em intervalos de quinze dias. As plantas foram fracionadas em raiz, caule e folhas para a determinação das suas respectivas massas secas. A área foliar também foi mensurada e foram calculados os índices de crescimento. Os dados obtidos foram analisados por meio de regressão. Entre 75 e 156 dias após o transplantio (DAT), ocorreu o maior acúmulo de massa seca pela planta, caracterizando a fase de maior crescimento. Para maior rendimento de ramas, as plantas devem ser colhidas entre 60 e 87 DAT; para maior rendimento de raízes, a colheita deve ser realizada 180 DAT. O período de 80 a 118 DAT foi o mais adequado para a colheita simultânea de raízes e ramas, obtendo-se as maiores produtividades para ambos. Logo, a época ideal de colheita na batata-doce depende da sua finalidade de uso e de índices fisiológicos associados aos objetivos do cultivo.

ABSTRACT This research was installed to study plant growth of sweet potato and identify the most favorable harvest time for both roots and the aboveground part (stems). The experiment was carried out at the JK campus of the Federal University of the Vale do Jequitinhonha e Mucuri, in Diamantina, MG, complete blocks at random, with four replications. Three plants in the central part of the experimental plots were collected in twelve consecutive harvests at 15-day intervals. Plants were fractionated in roots, stems, and leaves to determine the dry matter of each part. Leaf area was also measured and growth rates were calculated. Data were analyzed by means of regression. Plants reached the highest dry matter accumulation between 75 and 156 days after transplanting (DAT), which corresponded to the phase of greatest growth. Plants should be harvested between 60 and 87 DAT to achieve the highest stem yield. For the highest root yield, the harvest should be carried out 180 DAT. The period from 80 to 118 DAT was the most adequate for reaching simultaneously the highest yields for both roots and stems. Therefore, the ideal harvest time for sweet potatoes depends on the use intended for the plant and on the physiological indexes associated with it.

ABSTRACT. The aim of this study was to obtain information for the genetic improvement of kale through repeatability and phenotypic stabilization studies and to compare methodologies that represent the reliability of the estimated parameters. Thirty-three half-sib progenies were evaluated in a randomized block design with three replicates and six plants per plot. Eight harvests were evaluated in terms of the yield of fresh leaves, number of shoots, number of leaves and average mass of leaves. Then, a phenotypic repeatability and stabilization study was performed, estimating the genetic parameters σ2a, σ²g, σ²e, and the coefficient of environmental variation and repeatability using the frequentist and Bayesian methodologies. To evaluate the reliability of these estimates, intervals were obtained using the frequentist, Bayesian and bootstrap methods. It was verified that the reliable selection of progenies of half-sib of kale can be achieved in four harvests that were realized between 95 and 170 days after planting. It was observed that the frequentist and Bayesian methodologies are better suited to obtain reliable estimates of the genetic parameters evaluated, as the last one provided smaller amplitudes for the obtained intervals. The bootstrap methodologies are not recommended for phenotypic repeatability and stabilization studies in kale.
