ABSTRACT Objective: Vitamin D has taken center stage in research and treatment of multiple sclerosis (MS). The objective of the present study was to assess the serum vitamin D levels of a large population of patients with MS and controls living in a restricted tropical area. Methods: Data from 535 patients with MS and 350 control subjects were obtained from 14 cities around the Tropic of Capricorn. Results: The mean serum 25-OH vitamin D level was 26.07 ± 10.27 ng/mL for the control subjects, and 28.03 ± 12.19 ng/mL for patients with MS. No correlation was observed between vitamin D levels and the disability of patients over the disease duration. Conclusion: At least for the region around the Tropic of Capricorn, serum levels of vitamin D typically are within the range of 20 to 30 ng/mL for controls and patients with MS.

ABSTRACT Transcranial doppler (TCD) is a strategic component of primary stroke prevention in children with sickle cell disease (SCD). This study was conducted to examine the TCD characteristics of children with SCD in nine different medical centers in Brazil. Methods: Transcranial doppler was performed in accordance with the Stroke Prevention Trial in Sickle Cell Anemia Protocol. Results: Of the 396 patients, 69.5% had homozygous SS hemoglobin. The TCD result was abnormal in 4.8%, conditional in 12.6%, inadequate in 4.3% and abnormally low in 1% of patients. The highest mean flow velocities were 121±23.83cm/s and 124±27.21cm/s in the left and right middle cerebral artery respectively. A total of 28.8% patients (mean age 9.19±5.92 years) were evaluated with TCD for the first time. Conclusions: The SCD patients were evaluated with TCD at an older age, representing an important missed opportunity for stroke prevention. Since TCD screening in patients with SCD is important to detect those at high risk for stroke, it is recommended that this screening should be made more readily available.

Published: January 2017

ABSTRACT Objective: The nasal cycle, which is present in a significant number of people, is an ultradian side-to-side rhythm of nasal engorgement associated with cyclic autonomic activity. We studied the nasal cycle during REM/non-REM sleep stages and examined the potentially confounding influence of body position on lateralized nasal airflow. Methods: Left- and right-side nasal airflow was measured in six subjects during an eight-hour sleep period using nasal thermistors. Polysomnography was performed. Simultaneously, body positions were monitored using a video camera in conjunction with infrared lighting. Results: Significantly greater airflow occurred through the right nasal chamber (relative to the left) during periods of REM sleep than during periods of non-REM sleep (p<0.001). Both body position (p < 0.001) and sleep stage (p < 0.001) influenced nasal airflow lateralization. Conclusions: This study demonstrates that the lateralization of nasal airflow and sleep stage are related. Some types of asymmetrical somatosensory stimulation can alter this relationship.

ABSTRACT Objective: To evaluate the mandatory folic acid fortification of flour on mortality rates after the hospital discharge of children born with myelomeningocele, the most affected age group and the most frequent cause of death. Methods: A retrospective study of 383 children born with myelomeningocele from January 1990 to December 2013 in a high-fetal-risk reference hospital. Results: A total of 39 patients died (10.1%),of which 23 (6%) died after discharge. Most children who died were younger than 12 months of age. The most frequent cause of death was infection of the central nervous system, followed by urinary tract sepsis and infections of the respiratory system. Symptomatic Chiari II malformation was the most frequent comorbidity factor. Conclusion: Although there was no significant difference in infant mortality before and after folic acid fortification, there was a significant reduction in deaths after hospital discharge in babies born after implementation of mandatory folic acid fortification

ABSTRACT Alcohol consumption aggravates injuries caused by ischemia. Many molecular mechanisms are involved in the pathophysiology of cerebral ischemia, including neurotransmitter expression, which is regulated by microRNAs. Objective: To evaluate the microRNA-219 and NMDA expression in brain tissue and blood of animals subjected to cerebral ischemia associated with alcoholism. Methods: Fifty Wistar rats were divided into groups: control, sham, ischemic, alcoholic, and ischemic plus alcoholic. The expression of microRNA-219 and NMDA were analyzed by real-time PCR. Results: When compared to the control group, the microRNA-219 in brain tissue was less expressed in the ischemic, alcoholic, and ischemic plus alcoholic groups. In the blood, this microRNA had lower expression in alcoholic and ischemic plus alcoholic groups. In the brain tissue the NMDA gene expression was greater in the ischemic, alcoholic, and ischemic plus alcoholic groups. Conclusion: A possible modulation of NMDA by microRNA-219 was observed with an inverse correlation between them.

Abstract Objective: To assess the feasibility and reliability of apparent diffusion coefficient (ADC) measurements of normal adrenal glands. Materials and methods: This was a retrospective study involving 32 healthy subjects, divided into two groups: prepubertal (PreP, n = 12), aged from 2 months to 12.5 years (4 males; 8 females); and postpubertal (PostP, n = 20), aged from 11.9 to 61 years (5 males; 15 females). Diffusion-weighted magnetic resonance imaging (DW-MRI) sequences were acquired at a 1.5 T scanner using b values of 0, 20, 500, and 1000 s/mm2. Two radiologists evaluated the images. ADC values were measured pixel-by-pixel on DW-MRI scans, and automatic co-registration with the ADC map was obtained. Results: Mean ADC values for the right adrenal glands were 1.44 × 10-3 mm2/s for the PreP group and 1.23 × 10-3 mm2/s for the PostP group, whereas they were 1.58 × 10-3 mm2/s and 1.32 × 10-3 mm2/s, respectively, for the left glands. ADC values were higher in the PreP group than in the PostP group (p < 0.05). Agreement between readers was almost perfect (intraclass correlation coefficient, 0.84-0.94; p < 0.05). Conclusion: Our results demonstrate the feasibility and reliability of performing DW-MRI measurements of normal adrenal glands. They could also support the feasibility of ADC measurements of small structures.

Abstract In the appropriate clinical setting, certain aspects of extranodal abdominal lymphoma, as revealed by current cross-sectional imaging techniques, should be considered potentially diagnostic and can hasten the diagnosis. In addition, diagnostic imaging in the context of biopsy-proven lymphoma can accurately stage the disease for its appropriate treatment. The purpose of this article was to illustrate the various imaging aspects of extranodal lymphoma in the abdomen.
Reação de cultivares de algodoeiro a Rhizoctonia solani na fase de plântula e benefícios do tratamento de sementes com fungicidas
Authors: Goulart Augusto César Pereira ,   Embrapa Agropecuária Oeste,  Brasil
Published: January 2017

RESUMO O objetivo desse trabalho foi avaliar a reação de onze genótipos de algodoeiro ao fungo Rhizoctonia solani AG-4, na fase de plântula, com potencial de uso em futuros programas de melhoramento bem como os benefícios do tratamento de sementes com fungicidas para cada cultivar em estudo. O experimento foi conduzido por dois anos nas casas de vegetação da Embrapa Agropecuária Oeste, em Dourados, MS. Sementes de cada cultivar, não tratadas e tratadas com a mistura fungicida tolylfluanid + pencycuron + triadimenol (30+50+50g do i.a./100kg de sementes), foram semeadas em areia contida em bandejas plásticas, dispostas em orifícios individuais, eqüidistantes e a 3cm de profundidade. A inoculação com R. solani foi feita pela distribuição homogênea do inóculo do fungo na superfície do substrato (2,5g do inóculo do fungo/bandeja plástica com dimensões de 56x35x10cm). O fungo foi cultivado por 35 dias em sementes de aveia preta autoclavadas e trituradas em moinho (1mm). As avaliações foram realizadas com base no desenvolvimento de sintomas e sobrevivência das plântulas, utilizando os dados de emergência inicial e final, tombamento de pós-emergência e plântulas lesionadas pelo patógeno. Foi observado efeito significativo da interação cultivares x tratamento com fungicidas (P<0,05). Ficou claramente demonstrada a importância do tratamento das sementes de algodoeiro com fungicidas, sendo que as melhores emergências e os menores índices de doença (tombamento e plântulas lesionadas), independente da cultivar testada, foram obtidos quando as sementes foram tratadas. Em relação as cultivares avaliadas na ausência do tratamento da sementes com fungicidas, observou-se comportamento diferenciado de alguns genótipos com relação ao ataque do fungo R. solani, merecendo destaque BRS Aroeira, seguidas de BRS Cedro, BRS Ipê e FMT 701, demonstrando uma maior tolerância destas cultivares ao ataque de R. solani em comparação às demais. Enfatiza-se que a resistência, sozinha, não é suficiente para proporcionar efetivo controle desse patógeno. Porém, pode ser útil se integrada a outras estratégias complementares de controle, como o tratamento de sementes com fungicidas, reforçando o conceito de manejo integrado de doenças.

Authors: Marcuzzo Leandro Luiz ,   Instituto Federal Catarinense,  Brasil, Duffeck Maira Rodrigues
Published: January 2017

RESUMO No presente trabalho foram estudadas, em condições controladas para o desenvolvimento de um modelo climático baseado na influência da temperatura (10, 15, 20 e 25°C) e da duração do molhamento foliar (6, 12, 24 e 48 horas) na severidade do míldio da cebola incitado por Peronospora destructor. A densidade relativa de lesões foi influenciada pela temperatura e pela duração do molhamento foliar (P<0,05). A doença foi mais severa na temperatura de 15°C. Os dados foram submetidos à análise de regressão não linear. A função beta generalizada foi usada para ajuste dos dados de severidade e temperatura, enquanto uma função logística foi escolhida para representar o efeito do molhamento foliar na severidade do míldio da cebola. A superfície de resposta obtida pelo produto das duas funções foi expressa por SE = 0,1506 * (((x-8)0,0614) * ((30-x)0,1419)) * (0,71642/(1+0,56954 * exp (-0,04460*y))), onde SE, representa o valor da severidade estimada (0,1); x, a temperatura (ºC) e y, o molhamento foliar (horas). Este modelo climático deverá ser validado em condições de campo para aferir o seu emprego como um sistema de previsão computacional para o míldio da cebola

ABSTRACT Propagation of “coquinho-azedo” (Butia capitata) is limited due to dormancy and high incidence of fungi in its seeds. The aim of this study was to evaluate the effect of treating “coquinho-azedo” seeds with different concentrations of bactericide and/or fungicide on the incidence of fungi and on the germination of seeds. Thus, B. capitata seeds were immersed in four doses of the bactericide kasugamycin (0, 1.5, 3.0 and 4.5 mL/L) and/or in four concentrations of the fungicide carbendazim+ thiram (0, 2.92, 5.84 e 8.75 mL/Kg), totaling 16 treatments. After the treatments, the operculum was removed from the seeds, which were placed on trays containing autoclaved sand, covered with transparent plastic film and kept in the nursery. In the germination test, treatments were distributed in randomized block design, factorial arrangement of 4x4 (bactericidal doses x fungicide doses), with four replicates of 50 seeds per plot. For the test of seed health quality, the Blotter test was employed in completely randomized design, using 20 replicates and 10 seeds. Health quality and germination were evaluated at 15 and 40 days after the treatment of seeds, respectively. There was no interaction between the bactericide and the fungicide on germination and control of fungi associated with seeds. However, there was an effect of fungicide concentrations on the evaluated parameters. We observed a negative correlation between the concentrations of the fungicide carbendazim + thiram and fungal incidence, and a positive correlation between the fungicide concentrations and seed germination. Therefore, fungicide treatment reduces the fungal incidence and provides better germination of B. capitata seeds.

RESUMO O mofo cinzento, causado por Botrytis cinerea, é responsável por mortalidade em mudas de Eucalyptus benthamii. O controle biológico é uma alternativa, devido à falta de produtos registrados para eucalipto no Brasil. Este estudo avaliou o fungo endofítico Trichoderma atroviride, isolado de eucalipto, para controle de B. cinerea. O ensaio consistiu na aplicação de uma suspensão de esporos de T. atroviride em mudas de E. benthamii, 24, 48 ou 72 horas antes de inocular B. cinerea. Como controle positivo utilizou-se iprodione. Mudas inoculadas foram mantidas em casa de vegetação por 21 dias. A severidade foi avaliada com auxílio de escala de sintomas de 0 (sem lesões) a 4 (alta severidade). Trichoderma atroviride reduziu significativamente a severidade da doença, independentemente do tempo de aplicação prévio, de modo similar ao fungicida.

Published: January 2017

ABSTRACT Experiments were carried out in a growth chamber and laboratory to quantify the curative and eradicant actions of fungicides in Asian soybean rust control. The experiments were conducted with the CD 214 RR cultivar, assessing the following fungicides, separately or in association, chlorothalonil, flutriafol, cyproconazole + trifloxystrobin, epoxiconazole + pyraclostrobin, cyproconazole + azoxystrobin, and cyproconazole + picoxystrobin. The fungicides were applied at four (curative) and nine days after inoculation (eradicant treatment). Treatments were evaluated according to the density of lesions and uredia/cm2, and the eradicant treatment was assessed based on the necrosis of lesions/uredia and on uredospore viability. Except for the fungicide chlorothalonil, there was curative action of latent/virtual infections by the fungicides. Penetrant fungicides that are absorbed have curative and eradicant action to soybean rust.

Published: January 2017

RESUMO Estudou-se a interferência da variabilidade da variabilidade climática e do número de relatos de ferrugem asiática na entressafra sobre a epidemia da doença no estado do Rio Grande do Sul, durante 11 safras agrícolas. A ocorrência da doença foi obtida a partir de relatos apresentados no Consórcio Antiferrugem e dividida entre os períodos “Safra”, “Entressafra” e “Ano Todo”. Os dados das epidemias foram testados para correlação, via regressões polinomiais lineares e quadráticas, com as variáveis climáticas: precipitação pluvial, índice padronizado de precipitação - SPI, índice de oscilação sul - IOS e anomalia da Temperatura na Superfície do Mar - SST no Oceano Pacífico Tropical e número de ocorrências da doença no período de entressafra. Os índices que melhor explicaram a variação das ocorrências da doença para o período “Ano Todo” foram o SST e IOS, com coeficientes de determinação (R2) de 0,94 e 0,59, respectivamente. As ocorrências de ferrugem no período “Entressafra” influenciaram positivamente nas ocorrências no período “Safra”.

Authors: Mei Lúcia Helena , Oliveira Natália
Published: January 2017

Resumo Este trabalho teve por objetivo avaliar a influência do tratamento químico da borra de café em relação as propriedades mecânicas e térmicas, morfologia e suscetibilidade à biodegradação quando utilizada na preparação de compósitos com Poli(ε-caprolactona) comparando-o com o polímero puro. A borra de café foi submetida ao tratamento álcali com hidróxido de sódio, seguida da acetilação. Os compósitos foram preparados utilizando diferentes porcentagens de borra de café. Com tratamento químico houve um aumento na estabilidade térmica da borra de café. Houve um aumento significativo no módulo elástico para o compósito com 10% de borra de café acetilada. As imagens obtidas por MEV mostraram uma parcial interação fibra/matriz para compósitos com borra acetilada. As análises térmicas mostraram que a adição de borra de café deslocou positivamente 10º C o pico máximo de degradação térmica em relação ao polímero puro. As amostras mais suscetíveis à biodegradação foram as que continham borra de café acetilada.

Published: January 2017

Resumo Neste trabalho foram desenvolvidas espumas flexíveis de poliuretano com a adição de celulose de Pinus nas concentrações de 0,5; 1 e 2% (m/m). A celulose foi submetida ao processo de fibrilação mecânica e posterior secagem por aspersão (spray dry) sendo caracterizada quanto a sua morfologia por MEV e MET. As espumas foram produzidas pelo método de batelada (one-shot) com a adição e mistura da fibra junto ao poliol. As espumas foram caracterizadas por MEV, densidade aparente e resistência à compressão. Os principais resultados indicam que a fibrilação mecânica promove a obtenção de fibras em escala nanométrica, porém durante a secagem, ocorre aglomeração ocasionando aumento para escala micrométrica. As propriedades mecânicas da espuma obtiveram acréscimos de 40 e 50% na resistência à compressão com a adição de 0,5 e 1% de celulose, respectivamente, evidenciando seu potencial como aditivo alternativo para o desenvolvimento de espumas de poliuretano.

Published: January 2017

Resumo Poli(3-hidroxibutirato) [P(3HB)] é um poliéster natural, biodegradável e é considerado um substituto atrativo para polímeros petroquímicos, pois tem a vantagem de ser degradado em solo dentro de alguns meses por micro-organismos. Este trabalho explora três estratégias para sintetizar P(3HB) a partir de Cupriavidus necator tendo glicerol como cosubstrato: cultivo sem glicerol, com adição de 20 g L–1 de glicerol na fase de produção do polímero e 20 g L–1 de glicerol no início do cultivo, a fim de avaliar o seu efeito sobre o crescimento celular e a síntese do polímero. Os resultados mostraram que a adição de glicerol no início do cultivo conduziu a maiores valores de percentagem de acúmulo de P(3HB) (64,12%). No entanto, nos experimentos sem glicerol podem ser observados maiores valores para fator de conversão em substrato (0,17 g g–1). Esses parâmetros apresentaram diferenças estatisticamente significativas em função da estratégia de cultivo utilizado.

Resumo Neste trabalho partículas de níquel foram incorporadas através da mistura física do pó resultante da mistura PVDF/Pani obtido por síntese química. Filmes homogêneos foram obtidos através da prensagem a temperatura de 180°C. A partir dos resultados pode-se notar alterações favoráveis e desfavoráveis nas propriedades do compósito após a incorporação e como estas tornam-se dependentes da incorporação. Os resultados de difratometria apresentaram picos característicos tanto da fase α da matriz polimérica e das partículas de níquel, e juntamente com as analises térmicas, que não há alteração na estrutura conformacional e a configuracional. Mesmo apresentando uma boa estabilidade térmica a incorporação indica que além da presença do polímero condutor como o aumento de partículas são prejudiciais às propriedades mecânicas finais da amostra. As micrografias apresentam as partículas de forma dispersas ao longo do filme e determinantes para os valores de condutividade elétrica e obtenção de uma fase magnética.

Abstract The objective of the present study was to learn which species of Squamata reptiles occur in Protected Area São José, in Tiradentes, Minas Gerais, Brazil. Between November 2009 and December 2010 reptiles were captured. In total 157 specimens were recorded of 29 species, 16 snakes, 12 lizards and one amphisbaena. Among the snakes, Dipsadidae showed the greatest richness, with a total of nine species. The group of snakes had the highest number of species present in the community, but 79% of sampled specimens were lizards, Enyalius bilineatus being the most abundant species, with 21% of occurrence. The area with the highest richness was the Cerradão. The lower abundance was found in the Gallery Forest area (n=14), but it was the vegetation type with the highest equitability. Areas of Cerradão and Cerrado sensu strictu showed the most similarity. In these areas five species were recorded in common, Bothrops neuwiedi (n=3) being the only species of snake, and the two species of lizards most abundant in both environments were Enyalius bilineatus (n=32) and Ameivula ocellifera (n=19). Ophiodes striatus and Xenodon merremii were common to Cerradão and Dirty Field areas. There was no species recorded that were common to the environments of Cerrado and Dirty Field but two species not sympatric were found of the same genus, Tropidurus torquatus, which was found only in the Cerrado sensu strictu and Tropidurus itambere exclusively in Dirty Field. Since none of the rarefaction curves reached full asymptote, this highlights the need for further study due to the high probability of new species being recorded for the studied area.

Abstract The capture of wild animals can provide important information on community structure, population dynamics, home range size, activity patterns, habitat use, denning, social behavior and health status. The objective of this study was to describe the method of capture with details on baits, injuries, non-target captures, anesthesia and costs, to evaluate its success as part of a health evaluation program of ocelots in a Brazilian Atlantic Forest Reserve. From a total of 1,011 trap-night effort in 86 days, we had 68 capture events composed of ocelots (22%, n=15) and non-target species (78%, n = 53). We captured 10 individual ocelots in 15 capture events, corresponding to 5.7 days to capture one ocelot. Capture efficiency was 14.8 ocelots/1,000 trap-nights effort. We suggest capture methods should be selected and implemented based on the following criteria: (i) high capture efficiency; (ii) high selectivity; (iii) low injury rate; (iv) high immobilization suitability; and (v) low costs, in order to enable comparisons of studies from different research groups and from different study areas, allowing a deliberate choice of the best method.

Published: January 2017

Abstract Oligochaeta is one of the most common and abundant taxon in continental aquatic fauna. However, knowledge of their distribution in Brazilian ecosystems is still incomplete and fragmented. Thus, the aim of this study was to develop an inventory of aquatic oligochaetes in the Extractive Reserve of Lake Cuniã in the State of Rondônia, Brazil. Collections of data were performed during the dry (August 2015) and rainy seasons (February 2016). The sediment samples were collected near the lakeside region using the kick sampling method and a kick-net sampler (mesh size of 0.25mm). This paper provides a catalog with 12 taxon from a total of 383 specimens, distributed into two families: Naididae (95.08%) and Opistocystidae (4.92%). The Pristininae subfamily was the most significant (85.68%), followed by subfamilies: Naidinae (8.36%), Tubificinae (0.52%) and Rhyacondrilinae (0.52%). In addition, some species such as Allonais inaequalis, Aulophorus furcatus, Dero nivea, Pristina synclites, Pristina menoni and Opistocysta serrata, were recorded for the first time in the Brazilian Amazon region. Therefore, the results of this study contribute to increase knowledge on the distribution of the Oligochaeta class in Brazil, particularly in the North of the country, which is so extensive and rich in water resources, but not extensively studied.

Resumo Contexto A insuficiência venosa crônica (IVCr) é frequente e predomina nas mulheres, mas ainda há poucas informações sobre o refluxo nas veias safenas na população masculina. Objetivos Identificar os diferentes padrões de refluxo nas veias safenas magnas (VSMs) e parvas (VSPs) em homens, correlacionando esses dados com a apresentação clínica conforme a classificação Clínica, Etiológica, Anatômica e Fisiopatológica (CEAP). Métodos Foram avaliados 369 membros inferiores de 207 homens pela ultrassonografia vascular (UV) com diagnóstico clínico de IVCr primária. As variáveis analisadas foram a classificação CEAP, o padrão de refluxo nas VSMs e VSPs e a correlação entre os dois. Resultados Nos 369 membros avaliados, 72,9% das VSMs apresentaram refluxo com predominância do padrão segmentar (33,8%). Nas VSPs, 16% dos membros inferiores analisados apresentaram refluxo, sendo o mais frequente o padrão distal (33,9%). Dos membros classificados como C4, C5 e C6, 100% apresentaram refluxo na VSM com predominância do refluxo proximal (25,64%), e 38,46% apresentaram refluxo na VSP com equivalência entre os padrões distal e proximal (33,3%). Refluxo na junção safeno-femoral (JSF) foi detectado em 7,1% dos membros nas classes C0 e C1, 35,6% nas classes C2 e C3, e 64,1% nas classes C4 a C6. Conclusões O padrão de refluxo segmentar é predominante na VSM, e o padrão de refluxo distal é predominante na VSP. A ocorrência de refluxo na JSF é maior em pacientes com IVCr mais avançada.

Abstract Objectives: to perform a cross-cultural adaptation of "Hoja Verde de Salud Medioambiental Reproductiva", originally conceived in Spanish for Brazilian Portuguese. Methods: the translation and cross-cultural adaptation process was carried out in five stages: translation, synthesis of the versions, back-translation, the acquisition of a consensual version after reviewed by the committee specialists and the application of the pretest to obtain the final version. The interviews were carried out at two reference services in maternal and child health, both located in Recife, Pernambuco, which provided medical care for high-risk pregnancies with a diversified clientele regarding the region of the State. Results: there were difficulties in understanding some words during the pretest and the precision of dates for medication use, radiation tests, as well as weeks of pregnancy and breastfeeding duration in weeks. The committee specialists made some alterations on the questionnaire considering suggestions made by the interviewees. Conclusions: after the adaption process, an available instrument in detecting environmental risks which might be incorporated in the maternal and child health routines and could contribute in detecting and preventing diseases and the severities and promote health for Brazilian children.

Abstract Objectives: to analyze maternal conceptions about the conditions of stimulating and discouraging breastfeeding before and after the educational intervention. Methods: An intervention study type pretest/posttest was conducted for 113 women attended at a public health service. An adapted cross-cultural questionnaire was applied to identify the conceptions of pregnant women about the conditions of stimulating and discouraging breastfeeding. The effect of the intervention was verified by assessing the Decisional Balance scores before and after the intervention. Results: there was a reduction in the overall score of the discouraging conditions and an increase of the overall score of the stimulating conditions (p<0.001). In evaluating each discouraging condition, a significant reduction in the affirmative scores was observed as "breastfeeding makes the breasts saggy" (p=0.003), "I think my breasts are too small to have enough breast milk for my baby" (p=0.001). Regarding to the stimulating conditions, it showed a significant increase in the affirmative score for "breastfeeding is good for me" (p=0.006), "breastfeeding can help me lose weight" (p=0.013), "breastfeeding is easy" (p=0.004). Conclusions: the intervention resulted in changing maternal conceptions of breastfeeding and can be an interesting strategy on promoting breastfeeding in health services.

Abstract Objectives: to identify the characteristics of pregnant women who had premature child-birth (PPT) in the South region of São Paulo city. Methods: a cross-sectional observational study with a data collection of 122 medical files on pregnant women who had PPT in 2013. The collected data were analyzed by a statistical package, Graphpad Prism 6. As for the variables that were shown to be significant in the multivariate regression, an analysis was performed in a dichotomous form by odds ratio. Results: the mean age of the pregnant women was 24.9 years old. Of the 122 pregnant women, 34.4% were included in the age group considered to be at risk by the Ministry of Health. The predominant race was mixed (46.2%). 41.8% were high school graduates. Regarding to personal background, the history on urinary infection was mostly mentioned (37.5%). In relation to family history regarding clinical conditions, 43% had diabetes history and 61% had hypertension. As for gynecological history, 37.5% reported having dysmenorrhea during menstrual cycles. Multivariate analysis was performed and found that particularly hypertension and dysmenorrhea were the most significant. Conclusions: Regarding to women´s risk factors for premature childbirth, the most determining factor was dysmenorrhea, followed by hypertension.

Published: January 2017

Abstract Objectives: this study aims to evaluate parturition distribution of live-born children within the First Health Regional Administration (GERES I) in the state of Pernambuco, Brazil in 2012. Methods: live Birth Certificates were used to evaluate displacements between pregnant women's residential municipalities and birth localities. Flux maps were constructed to represent pregnant women transferred to Recife, and the estimated number of live-borns with high-risk and regular births was calculated for each municipality. Results: in 2012, only 50% of the births of live babies in the GERES I took place at the original residential municipality of the mother. In Recife, the number of childbirths was 1.5 times greater than expected for this year, with 56% representing non-residents. Eleven municipalities of the GERES I have maternity hospitals, however, none of these responded to the expected number of regular risk births. Conclusions: this disruption of the obstetric network leads to the disrespecting of women's right to know beforehand the place of childbirth and to create bonds with it. Municipalities perform fewer childbirths than expected, resulting in unnecessary transfers and the overloading of maternity hospitals in Recife.

Abstract Introduction: several birth defects associated to congenital Zika virus infection have been reported, although the clinical features have not been fully characterized. Description: this is the first case report on unilateral diaphragmatic paralysis diagnosed on a neonate with congenital Zika confirmed by the examination of the amniotic fluid through polymerase chain reaction (ZIKV RT-PCR) and the examination of cerebrospinal fluid by serological test (IgM ZIKV-ELISA) after birth. The main manifestations detected by intrauterine ultrasound were: microcephaly, ventriculomegaly, intracranial calcifications, enlarged cisterna magna, increased amniotic fluid index and fetal akinesia syndrome. The newborn had acute respiratory failure in the first hours of life, requiring mechanical ventila-tion. The X- ray of the chest showed unilateral diaphragmatic paralysis and cardiomegaly. Discussion: diaphragmatic palsy in congenital Zika has not been previously reported, the etiopathogenic mechanisms of this event in congenital Zika virus needs to be elucidated.

Resumo Este artigo busca avaliar a presença de uma democracia inercial no Brasil, em que as assimetrias entre economia e política produzem uma cultura política passiva e anômica. Tal situação possibilita que as políticas sociais e econômicas sigam um padrão que pouco se modifica. Se, num contexto de mudanças, as coisas precisam mudar para que fiquem iguais, então se pode esperar que, num contexto de (re)democratização com inércia, as instituições mudem, sem, no entanto, alterar, numa direção positiva, as normas, os valores e as crenças normativas da população em relação à democracia. Para analisar essa proposição serão utilizados dados demográficos e socioeconômicos, avaliados ante a evolução da confiança nas instituições, governantes e na democracia no período 2002-2014, a partir de dados do Eseb. A conclusão é de que o período de desempenho econômico favorável não permitiu a consolidação de uma cultura política democrática, com rápida deterioração do apoio às instituições e aos governantes a partir da crise econômica.

Resumo Este artigo analisa os determinantes da avaliação econômica retrospectiva sociotrópica na eleição presidencial no Brasil em 2014, com base: a) no conhecimento que o eleitor possui a partir de informação objetiva da economia; b) no conhecimento que o eleitor possui a partir de sua experiência vivida/sensação de mobilidade social; c) a sua afetividade partidária; d) a sua identidade ideológica. Nossa contribuição foi mostrar que: a) ter conhecimento/informação objetiva da economia não tem impacto na avaliação da economia; b) o conhecimento advindo da experiência vivida, identificado aqui como sensação de mobilidade social, não impacta na avaliação da economia no sentido esperado – mais ascensão, mais tendência de avaliação positiva; c) a afetividade partidária, por sua vez, demonstrou forte impacto na avaliação da economia. O artigo usa dados do CSES/Eseb – Estudo Eleitoral Brasileiro.

Resumo Neste artigo analisamos o impacto da identificação partidária sobre o comportamento eleitoral no Brasil. Usamos dados do Eseb realizado em 2014 com uma amostra representativa de eleitores de âmbito nacional. Em relação aos outros trabalhos a respeito do impacto da identificação sobre o voto, inovamos em dois aspectos. Primeiro, não nos limitamos à análise do voto para presidente, mas incluímos o voto para todos os cargos em disputa em 2014. Segundo, mostramos que a identificação partidária não atua da mesma forma sobre todos os eleitores identificados com um mesmo partido. Mostramos que partidários do PT são mais coerentes no seu voto para presidente quando têm maior nível de instrução, ao passo que os partidários do PSDB são mais fiéis na mesma questão quando têm baixa instrução. Da mesma forma, petistas são fiéis na hora de votar no presidente, enquanto os peessedebistas votam com seu partido na hora de escolher governadores e senadores. Finalmente, nossa análise identificou um padrão complexo entre as variáveis educação, aqui tomada como proxy dos recursos cognitivos do eleitor, identidade partidária e decisão de voto. Essa última contribuição leva a discussão sobre a identificação partidária no Brasil para além das questões sobre sua presença ou ausência no eleitorado, e sua relevância para entender a decisão de voto, que são as abordagens dominantes na literatura que trata do tema.
