Risk of Rupture and Risks of Endovascular Management of Unruptured Brain Arteriovenous Malformations
Authors: Shen Xun , Liu Jie , Lv Xianli , Li Youxiang
Published: April 2014

This study reports the natural history of unruptured brain arteriovenous malformations (AVMs) and the risks involved in their endovascular management.

A total of 242 patients at our center were enrolled in the study, which had retrospective and prospective components. We retrospectively assessed the morbidity and mortality related to endovascular management in 125 patients with unruptured AVMs. We prospectively assessed the natural history of unruptured AVMs in 117 patients with newly diagnosed unruptured AVMs; 48 of the patients had no history of seizure (Group 1), whereas 69 had a history of seizure from the lesion (Group 2). The retrospective group was also divided into patients with and without seizures.

The cumulative rate of rupture of AVMs in Group 2 was less than 0.8% per year, while the rate was approximately sixfold higher (5.1% per year) in Group 1. The overall cumulative rate of rupture of AVMs was less than 3.0% per year. The overall rate of endovascular management-related morbidity and mortality was 10.6% in Group 2 and 11.9% in Group 1 at 30 days and was 25.9% and 13.6%, respectively, at one year. There was no independent predictor of a poor endovascular outcome.

The likelihood of rupture of unruptured AVMs was exceedingly low among patients in Group 2 and was substantially higher among those in Group 1. The risk of morbidity and mortality related to endovascular management greatly exceeded the six-year risk of rupture among patients in Group 2. Endovascular management of an AVM should not be performed to eliminate or to improve seizure frequency.

Aneurysms with an acutely angled parent artery are difficult to access for coiling. This study aimed to investigate the safety and effectiveness of microcatheter looping for embolization of cerebral aneurysms with access difficulty.

Ten patients (male:female=5:5) with cerebral aneurysms treated with the microcatheter looping technique were analyzed retrospectively. The parent artery formed an acute angle with the major artery in five aneurysms. The microcatheter was looped into a “α” loop for treatment in the anterior temporal artery aneurysm and a “U” loop in the remaining nine aneurysms.

All ten aneurysms were successfully treated with the microcatheter looping technique. The microcatheter tip was successfully navigated into the aneurysm sac and remained stable throughout the embolization process. All aneurysms were occluded with total occlusion in five and near-total occlusion in five, and the parent artery remained patent in all cases. No complications occurred peri-procedurally. The Glasgow Outcome Scale was 5 in all patients before discharge. Follow-up angiography six to 12 months later revealed a good occlusion status of the aneurysms.

The microcatheter looping technique is effective when the conventional embolization technique fails to treat cerebral aneurysms with difficult access especially when the parent artery forming an acute angle with the major artery exacerbates difficult access to the aneurysms.
Percutaneous Sacroiliac Joint Fixation in Sacroiliac Instability
Authors: Manfré Luigi
Published: April 2014

The prevalence of sacroiliac Joint (SIJ) disease as a cause of LBP is considered to range from 21% to 25%. Nevertheless, SIJ instability is frequently underestimated. Although conventional surgery has been used for several years in an attempt to stabilize the SIJ, a new percutaneous system has been proposed for articular fusion. Recently a new “one-step” fixation procedure has been proposed. We describe the case of a patient with painful SIJ instability treated with a fully CT-guided technique in simple analogue sedation.

Published: April 2014

We describe a case of arteriovenous fistula (AVF) successfully treated by coil embolization with an anchor coil inserted in the varix to facilitate dense packing at the shunting site. AVF of the left anterior choroidal artery (AChoA) draining into the ipsilateral basal vein of Rosenthal was incidentally found in a newborn female. A single detachable coil was inserted as an anchor into the varix adjacent to the shunt, and the microcatheter was pulled back to the shunting point. Three more detachable coils were delivered at the shunting point without migration under the support of the anchor coil, and the AVF was successfully obliterated with preservation of AChoA blood flow. The anchor coil technique can reduce the risk of coil migration and the number of coils required.

Published: April 2014

This study includes 20 patients with 21 spinal perimedullary fistulae. There were nine Type IVa (42.8%) lesions, ten Type IVb (47.6%) and two Type IVc (9.5%) lesions. The dominant arterial supply was from the anterior spinal artery (47.6%), posterior spinal artery (19%) and directly from the radiculomedullary artery (28.5%). Sixteen lesions in 15 patients were treated by endovascular route using n-butyl-2-cyanoacrylate. Endovascular treatment was not feasible in five patients. Of the ten patients with microfistulae, catheterization failed/was not attempted in 40%, complete obliteration of the lesion was seen in 60% but clinical improvement was seen in 40% of patients. Catheterization was feasible in all ten patients with macrofistulae (nine type IVb and two type IVc lesions). Complete obliteration of the lesions was seen in 60% and residue in 30%. Clinical improvement was seen in 80% and clinical deterioration in 10%. In conclusion, endovascular glue embolization is safe and efficacious in type IVb and IVc spinal perimedullary fistulae and should be considered the first option of treatment. It is also feasible in many of the type IVa lesions.

Published: April 2014

The aim of this study was to compare in vivo the accuracy of two electronic foramen locators (EFLs) based on different operation systems - Root ZX and Propex II. Ten healthy adult patients needing premolar extractions due to orthodontic reasons participated in the study, providing a sample of 17 noncarious, non-restored, vital teeth (n= 24 canals). After coronal access preparation and cervical preflaring and prior to tooth extraction, the root canal length was measured alternating the two EFLs. All measurements were performed with K-files well fitted to the canal diameter at the level that each EFL indicated the apical foramen in their display (APEX or 0.0). The last K-file were fixed in place with cyanoacrylate, the tooth was extracted, and the apical 4 mm of each root were resected to measure the distance between the file tip and the apical foramen. The mean errors based on the absolute values of discrepancies were 0.30 ± 0.29 mm (Root ZX) and 0.32 ± 0.27 mm (Propex II). Analysis by the Wilcoxon test for paired samples showed no statistically significant differences between the electronic canal measurements performed with the EFLs (p=0.587). The apical foramen was accurately located in 75% (Root ZX) and 66.7% (Propex II) of the cases, considering a ±0.5 mm error margin, with no statistically significant difference by the chi-square test. Despite having different measurement mechanisms, both EFLs were capable of locating the apical foramen with high accuracy in vivo. Under the tested clinical conditions, Root ZX and Propex II displayed similar results.

Published: April 2014

The objective of this study was to evaluate the bacterial seal at the implant-abutment interface using two morse taper implant models, by means of an in vitro microbiological analysis. For that were used 15 implants with mini-abutments tightened by friction, no screws (Group 1); and 30 implants with screw-tightened abutments, of which 15 received 20 N.cm of closing torque (Group 2) and the other 15 received 30 N.cm (Group 3). Microbiological analysis was carried out using colonies of Escherichia coli transported directly from a culture dish to the prosthetic component. Friction implants (Group 1) were activated by tapping and a torque wrench was used for screw-tightened implants (Groups 2 and 3). Each abutment/implant set was immersed in test tubes containing 5 mL of brain-heart infusion broth and incubated at 37 °C for 14 days, observed daily for the presence of contamination. A statistically significant difference was observed regarding the number of contaminated implants. There was greater contamination in Group 2 implants (p<0.05), with no statistically significant difference between the other groups (Group 1 = 20% and Group 3 = 0%). It was concluded that there was no significant difference in in vitro bacterial sealing between implants with mini-abutments tightened by friction without screws and implants with screw-tightened abutments with 30 N.cm of closing torque. The difference in closing torque altered the in vitro sealing ability of the tested abutments, with a greater contamination for components that received a closing torque of 20 N.cm.

Published: April 2014

During the cementation of ceramic veneers the polymerization of resin cements may be jeopardized if the ceramics attenuate the irradiance of the light-curing device. The aim of this study was to evaluate the effect of different types and thicknesses of ceramic veneers on the degree of conversion of a light-cured resin-based cement (RelyX Veneer). The cement was light-cured after interposing ceramic veneers [IPS InLine, IPS Empress Esthetic, IPS e.max LT (low translucency) and IPS e.max HT (high translucency) - Ivoclar Vivadent] of four thicknesses (0.5 mm, 1.0 mm, 1.5 mm and 2.0 mm). As control, the cement was light-cured without interposition of ceramics. The degree of conversion was evaluated by FTIR spectroscopy (n=5). Data were analyzed with one-way ANOVA and Tukey's test (α=0.05). Significant differences were observed among groups (p<0.001). The degree of conversion was similar to the control for all light-cured groups with interposition of ceramics of 0.5 mm and 1.0 mm (p>0.05). Among 1.5-mm-thick veneers, IPS e.max LT was the only one that showed different results from the control (p<0.05). At the thickness of 2.0 mm, only the IPS e.max LT and HT veneers were able to produce cements with degrees of conversion similar to the control (p>0.05). The degree of conversion of the evaluated light-cured resin cement depends on the thickness and type of ceramics employed when veneers thicker than 1.5 mm are cemented.

Published: April 2014

Temporomandibular disorders (TMD) are manifested as a group of signs and symptoms that affect a particular population profile. Some variables such as sex and age influence the clinical expression of this condition. This observational descriptive cross-sectional study aimed to correlate the severity of TMD established by the craniomandibular index (CMI) with the variables: age, sex and electromyographic activity of the masseter and anterior temporal muscles. Fifty-four subjects (15 males/39 females) aged between 16 to 65 years (mean age = 41 years) and diagnosed with TMD were evaluated. Severity was determined by the CMI. These subjects also underwent examination by surface electromyography of the masseter and anterior temporal muscles. No correlation was found between age and severity of TMD (p=0.19/r=0.16), however there was a trend of greater severity in young adults (25-50 years). The sex variable in the correlation was positive with the CMI (p=0.03/r=-0.96) and superior to women. A greater EMG activity of the anterior temporal in relation to masseter (p=0.01) was found and the left temporal activity had the highest average (161.5 ± 44.6 Hz). The electromyographic activity of the anterior temporal and right masseter muscles was positively correlated with the Dysfunction Index CMI (p=0.01). The use of CMI to quantify the severity of TMD and of EMG to assess the functionality of the masticatory muscles can be important allies to direct the treatment.

Published: April 2014

This study compared in situ the application of 4% titanium tetrafluoride (TiF4) solution and 2% sodium fluoride (NaF) gel on artificial white-spot lesions in human enamel. A crossover, double-blind study using in situ caries models was carried out. Eleven volunteers used an intraoral appliance containing five demineralized human enamel blocks. The blocks (n=170) were randomly divided according to treatment into the following groups: TiF4 (n=55), NaF (n=55), positive control (n=55). A negative control group was composed of demineralized specimens (n=5). The microhardness test was performed using a Knoop penetrator. Energy dispersive spectrometer (EDS) was used to analyze the concentration of titanium, calcium, phosphate and oxygen. The enamel microhardness at different depths for TiF4, NaF and positive control samples was not statistically different (p>0.05). The samples from these three groups had statistically higher microhardness values than the negative control samples (p<0.05). EDS analysis did not provide conclusive results about the penetration of titanium in the TiF4 samples. While in some fragments it had substantial penetration, in other fragments it only had superficial penetration. It was possible to conclude that, under in situ conditions, 4% TiF4 solution and 2% NaF gel were able to remineralize artificial white-spot lesions in human enamel. However, the magnitude of the remineralization did not differ between groups.

This study aimed to evaluate the factors associated with the decision to attend an academic post-graduation program by dental students. A cross-sectional study was conducted in 2012, last-year undergraduate students from Dental Schools of Southern Brazil. A closed questionnaire was applied including questions grouped in three different blocks: pre-graduate, undergraduate period and future perspectives. The outcome was the decision to pursuit an academic post-graduation degree. Associations were tested using chi-squared test and chi-squared test for linear trends when appropriate. Multivariate Poisson regression was also performed. The sample was composed by 671 students (response rate of 69.9%, n=467). In relation to future perspectives, 68% of the interviewed students intended to attend a post-graduation program, but only 17.5% would choose a program with academic and research post-graduation program (Master and PhD programs). In the final model, students from public universities (PR 2.08, 95%CI 1.41-3.08) and students that received scientific initiation scholarship (PR 1.93 95%CI 1.14-3.27) presented a twice greater prevalence to seek academic post-graduate programs. Students with higher family incomes showed a lower prevalence to seek these programs (PR 0.50, 95%IC 0.28-0.90). Scholarships seem to encourage undergraduate students to pursue stricto sensu post-graduation.

Authors: Alves Rodrigo Andrade , Miszputen Sender Jankiel , Figueiredo Maria Stella
Published: April 2014

CONTEXT AND OBJECTIVES:Anemia is the most frequent extraintestinal complication of inflammatory bowel disease. This study aimed to: 1) determine the prevalence of anemia among patients with inflammatory bowel disease; 2) investigate whether routine laboratory markers are useful for diagnosing anemia; and 3) evaluate whether any association exists between anemia and clinical/laboratory variables.DESIGN AND SETTING:Cross-sectional at a federal university.METHODS:44 outpatients with Crohn's disease and 55 with ulcerative colitis were evaluated. Clinical variables (disease activity index, location of disease and pharmacological treatment) and laboratory variables (blood count, iron laboratory, vitamin B12 and folic acid) were investigated.RESULTS:Anemia and/or iron laboratory disorders were present in 75% of the patients with Crohn's disease and in 78.2% with ulcerative colitis. Anemia was observed in 20.5% of the patients with Crohn's disease and in 23.6% with ulcerative colitis. Iron-deficiency anemia was highly prevalent in patients with Crohn's disease (69.6%) and ulcerative colitis (76.7%). Anemia of chronic disease in combination with iron deficiency anemia was present in 3% of the patients with Crohn's disease and in 7% of the patients with ulcerative colitis. There was no association between anemia and disease location. In ulcerative colitis, anemia was associated with the disease activity index.CONCLUSIONS:Most patients present iron laboratory disorders, with or without anemia, mainly due to iron deficiency. The differential diagnosis between the two most prevalent types of anemia was made based on clinical data and routine laboratory tests. In ulcerative colitis, anemia was associated with the disease activity index.

Authors: Oliveira Cristiane Moço Canhetti , Nogueira Paula Roberta
Published: April 2014

CONTEXT AND OBJECTIVE:There have been few studies on the risk factors for subgroups of stuttering. The aim of this study was to characterize the risk factors for developmental familial stuttering among boys who stutter and who do not stutter, such as disfluency types, associated quality and communication factors, emotional and physical stress, familial attitudes and personal reactions.DESIGN AND SETTING:Analytical cross-sectional study with a control group, performed at the Fluency Studies Laboratory of the Department of Speech and Hearing Disorders of a public university.METHODS: The parents of 40 age-matched stuttering and non-stuttering boys took part in this study. The participants were divided into two groups: stuttering children (SC) and non-stuttering children (NSC), with ages between 6 years 0 months and 11 years 11 months. Initially, all of the participants underwent a fluency assessment and then data were gathered using the Protocol for the Risk of Developmental Stuttering.RESULTS:There were no differences in the physical stress distribution factors and personal reactions between the groups. Inappropriate familial attitudes were presented by 95% of the SC and 30% of the NSC. Four risk factors analyzed were not shown by the NSC, namely stuttering-like disfluency, quality factors, physical stress and emotional stresses.CONCLUSIONS:The findings suggest that the presence of stuttering-like disfluency, associated quality and communication factors, emotional stress and inappropriate family attitudes are important risk factors for familial developmental stuttering among boys.

Published: April 2014

O estudo buscou conhecer a percepção de equipes de Saúde da Família sobre as relações trabalho-saúde-doença e identificar estratégias, facilidades e dificuldades para prover o cuidado aos trabalhadores. Foram realizados grupos focais com profissionais de unidades básicas em: Palmas (TO), Sobral (CE) e Alpinópolis (MG). Utilizou-se análise de conteúdo de Bardin para sistematização e análise dos dados. Os resultados revelam que as ações de cuidado dos trabalhadores são pontuais e pouco articuladas com as diretrizes e objetivos da Política Nacional de Saúde do Trabalhador e da Trabalhadora. Entre as dificuldades estão: sobrecarga de trabalho; despreparo das equipes para as questões que envolvem as relações trabalho-saúde-doença; falta de apoio institucional, entre outros. O apoio matricial às equipes de saúde pelos Centros de Referência em Saúde do Trabalhador e outras instâncias do SUS foi identificado como facilitador das ações.
Apoio institucional como fio condutor do Plano de Qualificação das Maternidades: oferta da Política Nacional de Humanização em defesa da vida de mulheres e crianças brasileiras

Published: April 2014

A Política Nacional de Humanização (PNH) tem experimentado apoio institucional como estratégia metodológica para interferir em modos de gerir e de cuidar no Sistema Único de Saúde (SUS), qualificando-os. Neste artigo pretendemos analisar a relação entre função apoio institucional e humanização, valendo-nos da experiência realizada no Plano de Qualificação de Maternidades (PQM), para o qual a contribuição da PNH centrou-se justamente no objetivo de desenhar a função apoio institucional. Tendo por base o entendimento de que, para mudar o modelo de atenção e de gestão ao parto e nascimento, é preciso interferir em práticas de saúde ‘desumanizadoras’, no PQM o apoio institucional se constituiu como fio condutor, cujo escopo foi o de, por meio da criação de espaços coletivos de análise e interferência nas práticas, tecer uma rede coletiva de produção de saúde materna e infantil.

Published: April 2014

Este relato é um registro cartográfico do apoio institucional junto a uma Secretaria Estadual de Saúde na articulação da rede regional de Saúde Mental. O apoio institucional é uma estratégia da Política Nacional de Humanização nas redes de atenção à saúde e dispositivo de fomento de espaços de cogestão. O relato está pautado em três eixos: a produção de coletivos e os afetamentos dos encontros entre gestores e trabalhadores; a ação articuladora do apoio institucional, as ofertas na análise e a implicação colegiada; e os desejos e a construção coletiva dos objetos de investimento. Com a vivência da função apoio como caminho da articulação e extraindo os sentidos desse fazer pelos desejos que mobilizam o agir, elaborou-se um olhar crítico para as fortalezas e fragilidades dos sujeitos institucionais e dos seus papéis na produção colegiada do cuidado em saúde mental.

Authors: Howat-Rodrigues Anna Beatriz Carnielli , Tokumaru Rosana Suemi
Published: April 2014

The aim of this study was to examine evidence of validity for the Brazilian version of the Scale of Family Unpredictability during childhood. A total of 740 people participated in the study. The first sample was composed of 121 women over 40 years of age (Xage= 5.86), 157 adults in conflict with the law (148 men, Xage= 34.20), and 251 college students (122 men,Xage= 19.60). The second sample included 211 college students (90 men, Xage= 21.53). Exploratory and confirmatory analysis indicated that the three-dimensional model (nurturance, money, meals) presented a better goodness of fit, with satisfactory reliability indexes. A significant effect of all unpredictability factors on the purchasing power of the participants was found, confirming validity by contrasting groups of EIFI: people belonging to socioeconomic classes with lower purchasing power presented higher family unpredictability during childhood. We concluded that the three-dimensional EIFI is psychometrically adequate, allowing the differentiation of groups in the constructs evaluated.

Published: April 2014

The aim of the current study was to analyse the influence of psychological, anthropometric and sociodemographic factors on the risk behaviours for eating disorders (ED) in young athletes. Participants were 580 adolescents of both sexes. We used the Eating Attitudes Test (EAT-26), theBody Shape Questionnaire and the Commitment Exercise Scale to assess the risk behaviours for ED, body image dissatisfaction (BD) and the degree of psychological commitment to exercise (DPCE), respectively. Participants’ weight, height and skinfold thickness were measured. A multiple regression indicated that BD and percentage of fat significantly modulated ( p < .05) the variance of females’ EAT-26 scores, whereas BD, DPCE, fat percentage, age, ethnicity and competitive level significantly explained ( p < .05) the variance of risk behaviours for males’ ED. Thus, only BD influenced risk behaviours for ED in both sexes.
Sources and Reactions to Stress in Brazilian Lawyers
Authors: Costa Maria de Fátima Antunes Alves , Ferreira Maria Cristina
Published: April 2014

Job stress can negatively affect the health of employees. As such, the investigation of its characteristics in different professional categories is relevant. The aim in this study was to analyze the predictive power of seven stressors (decision latitude, psychological demands at work, physical demands at work, social support from colleagues, ergonomic stressors, relationships with clients, job insecurity) for job dissatisfaction, depression and psychosomatic problems in a sample of 702 Brazilian lawyers. The data were collected using a Brazilian version of the Job Content Questionnaire(JCQ). The results showed that decision latitude and social support were the main negative predictors of stress, while psychological demands and job insecurity were its main positive predictors. These results are discussed in the light of the demand-support-control model, which was used as a framework for the research.
Smartphones and Location Awareness in Brazil: Users’ Reactions
Authors: Nicolaci-da-Costa Ana Maria , Matos-Silva Mariana Santiago de
Published: April 2014

The general objective of this study was to gain detailed information on how Brazilians are using the many features of their smartphones according to their own accounts. Among these features, of particular interest were the ways in which they react to and deal with the novelty presented by location awareness, especially in LBSN applications. A qualitative research guided by the Underlying Discourse Unveiling Method (UDUM) was carried out. Fifteen knowledgeable users of digital technologies aged between 23 and 38 were recruited in Rio de Janeiro and São Paulo. Open-ended-question interviews were conducted with each. Results revealed that location-sharing reinforced their pre-existing fears related to violence and criminality. They knew that criminals may have access to these technologies. Therefore, in order to protect their personal safety most participants avoided location-disclosure. The fears mentioned by them are embedded in the violent context they live in.
Entomopathogenic nematodes for the control of phorid and sciarid flies in mushroom crops
Authors: Navarro María Jesús , Gea Francisco José
Published: April 2014

The objective of this work was to evaluate the efficacy of two nematodes, Steinernema feltiae and S. carpocapsae, to control mushroom flies and to evaluate the effect of these treatments on Agaricus bisporus production. Two mushroom cultivation trials were carried out in controlled conditions, in substrate previously infested with the diptera Megaselia halterata and Lycoriella auripila, with two treatments: 106infective juveniles (IJ) per square meter of S. feltiae and 0.5x106IJ m-2S. feltiae + 0.5x106IJ m-2S. carpocapsae. Another experiment was carried out using the same treatments to evaluate the possible nematode effect on mushroom yield. The number of adults emerging from the substrate was evaluated for each fly species. No decrease in the population of M. halterata was detected with nematode application, whereas the number of L. auripila was reduced in both treatments, particularly in the individual treatment with S. feltiae. The application of entomopathogenic nematodes has no adverse effect on mushroom production.

Durante a estação de monta, de 85 dias, foram avaliadas 161 vacas de corte da raça Purunã, de acordo com os seguintes manejos de amamentação: desmame precoce, vacas separadas dos seus bezerros aos 75 dias pós-parto; amamentação controlada, vacas separadas de seus bezerros aos 75 dias de idade, mas colocadas para amamentar uma vez ao dia durante a estação de monta; e desmame convencional, vacas mantidas com seus bezerros ao pé até o final da estação de monta, aos 160 dias de idade dos bezerros, em média. As taxas de prenhez não foram significativamente afetadas pelos manejos de amamentação, tendo sido de 97% no desmame precoce, de 96% na amamentação controlada e de 90% no desmame convencional. No entanto, o desmame precoce resultou em menor eficiência reprodutiva (28,26 kg), quando comparado à amamentação controlada (35,09 kg) e ao desmame convencional (35,34 kg). Vacas de corte mantidas em boas condições corporais ao parto e ao início da estação de monta apresentam alta taxa de fertilidade, independentemente do manejo de amamentação dos bezerros.
Faces e metamorfoses do poder: uma sociografia dos ministros da educação no Portugal democrático
Authors: Abrantes Pedro , Roldão Cristina
Published: April 2014

O presente artigo caracteriza o perfil e a trajetória social dos 27 agentes que ocuparam o cargo de ministro da Educação em Portugal, desde a revolução democrática de 1974. Busca-se, com este estudo, contribuir para a análise dos grupos, interesses e ideologias que têm governado o sistema educativo no país, nas últimas décadas. Partimos de um quadro teórico em que se cruzam os estudos a respeito das elites políticas com as pesquisas sobre políticas educativas. Após um debate acerca da volatilidade do cargo, a análise centra-se na compreensão de um padrão observado: a larga maioria dos ministros são homens, nascidos em Lisboa, formados em certas escolas e cursos, com mestrado ou doutorado. Em geral, apresentam-se como independentes, têm carreiras ligadas à docência universitária, à administração pública e, em alguns casos, também à administração de empresas e fundações. É possível, ainda assim, observar mudanças ao longo das últimas décadas, nomeadamente, quanto à área de formação: os historiadores e filósofos do período revolucionário foram substituídos por engenheiros, nos anos 1980 e 1990, e, mais recentemente, por economistas e sociólogos. A formação pós-graduada no estrangeiro, sobretudo na Inglaterra e nos Estados Unidos, também consiste em um recurso importante. Conclui-se que, apesar das mudanças geradas pelos processos democráticos, os ministros da Educação mantiveram um perfil muito específico, buscando conciliar as elites político-econômica e cultural-intelectual, mas mantendo a distinção (e tensão) relativamente ao campo educativo e aos seus agentes, em particular, aos professores do ensino básico e secundário.

A educação superior exerce papel fundamental no desenvolvimento econômico de determinado país, no que condiz ao atendimento das demandas da sociedade. A qualidade no contexto da educação superior tem sido tema recorrente nos últimos anos, sobretudo a partir da criação do Sistema Nacional de Avaliação da Educação Superior (SINAES), que instituiu um sistema de avaliação institucional global e integrador condizente a todas as Instituições de Ensino Superior (IES) brasileiras, sendo responsável por produzir índices para mensuração da qualidade como o Indicador de Diferença dentre os Desempenhos Observado e Esperado (IDD), o Conceito Preliminar de Curso (CPC) e o IGC, Índice Geral de Cursos, que mede o desempenho global da instituição. Diante disso, este estudo tem como objetivo analisar o IGC das universidades públicas e privadas das cinco regiões brasileiras, no intuito de caracterizar o desempenho das IES por região e verificar possíveis discrepâncias intra e inter-regionais identificando oportunidades de melhoria. Os resultados evidenciaram desempenho superior das universidades públicas em todas as regiões, tendo maior destaque as regiões norte e sudeste. Quanto à variabilidade, as regiões Centro-Oeste e Norte apresentaram os melhores desempenhos ambos condizentes ao setor privado. No entanto, para realizar uma avaliação consolidada do desempenho das IES por região faz-se necessário analisar, de forma integrada, os resultados do IGC alinhados aos demais subsistemas de avaliação que integram a avaliação multidimensional do SINAES.
Experiência e linguagem em Walter Benjamin
Authors: Pires Eloiza Gurgel
Published: April 2014

Este artigo apresenta uma reflexão a respeito da teoria da linguagem benjaminiana. Walter Benjamin, filósofo e crítico literário alemão, nas primeiras décadas do século XX, produziu um estudo decisivo no qual a linguagem não pode ser considerada como mero instrumento de elaboração dos dados da realidade nem como simples abstração, mas é pensada como campo no qual emerge uma intrincada rede de relações entre conhecimento e experiência. Para o filósofo, a linguagem é o médium espiritual e histórico da experiência. O conceito de Erfahrung (experiência) atravessa toda a sua obra: desde um texto de juventude, escrito em 1913, intitulado Erfahrung (1933), em que o autor contesta o desinteresse dos entusiasmos juvenis em nome da experiência dos adultos, às teses de 1940. Esse conceito está intrinsecamente relacionado, em seus escritos, ao pensamento de que todas as manifestações e expressões humanas podem ser concebidas como linguagem e, essa, por sua vez, é então pensada na sua dimensão simbólica, ao contrário do que pretendiam os filósofos do esclarecimento quando apontavam, como condição para o verdadeiro conhecimento, uma racionalidade que separava o imaginário do pensamento. Na contramão do pensamento iluminista científico, o paradigma estético é fundamental nos escritos benjaminianos. A partir do acolhimento do conceito na imagem, evidenciam-se novas formas de conhecer. Nessa perspectiva, tentaremos discutir o pensamento de Benjamin mostrando as articulações e rupturas engendradas com as problematizações constituídas a partir das conexões existentes entre linguagem e experiência e sua relação com o campo educativo.

Authors: Silva Eduardo Just da Costa e , Silva Giselia Alves Pontes da
Published: April 2014

Objetivos: comparar as características clínicas e parâmetros ultrassonográficos em um grupo de crianças e adolescentes, recentemente diagnosticados como portadores de doença celíaca, com um grupo controle. Métodos: estudo clínico conduzido com amostra de 20 pacientes recentemente diagnosticados com doença celíaca e 35 pacientes assintomáticos sem doença celíaca. Ultrassonografias abdominais foram realizadas em todos os pacientes. Os casos foram submetidos às ultrassonografias durante a fase de investigação diagnóstica, ainda consumindo glúten. Foram avaliados parâmetros ultrassonográficos e ao Doppler, relacionados às características das alças intestinais, linfonodomegalias e alterações no fluxo sanguíneo esplâncnico. As diferenças de proporções entre os grupos foram avaliadas pelos testes do quiquadrado e exato de Fisher e a diferença de médias pelo teste t de Student. Resultados: as principais manifestações clínicas relacionadas à doença celíaca foram as digestivas, como diarréia (12/20), dor abdominal (14/20) e distensão abdominal (15/20). Pacientes com doença celíaca apresentaram maior diâmetro transverso das alças do delgado (p=0,001), maior peristaltismo intestinal (p=0,002), aumento do conteúdo líquido intestinal (p=0,02), e maior espessura parietal (p<0,001). Conclusões: alterações sugestivas de má digestão/absorção (aumento do diâmetro transverso das alças do intestino delgado, maior peristaltismo intestinal, aumento do conteúdo líquido) e o espessamento da parede intestinal em pacientes com queixas digestivas devem alertar o clínico para investigar a doença celíaca.

Objetivos: comparar a distância entre os músculos retos do abdome (MRA) e a prevalência da diástase (DMRA) nas regiões supra-umbilical e infraumbilical de primíparas e multíparas no pós-parto imediato e verificar quais fatores materno-infantis podem estar associados. Métodos: estudo transversal, incluindo 115 primíparas e 154 multíparas. Avaliou-se a DMRA 4,5 cm acima e abaixo da cicatriz umbilical. Correlacionouse com idade materna, índice de massa corporal (IMC), idade gestacional, peso, estatura, perímetro cefálico e torácico do recém-nascido (RN). Utilizouse test t de Student, correlação de Pearson, quiquadrado e regressão logística múltipla, p<0,05. Resultados: a distância entre os MRA supraumbilical foi 3,04 (±1,68) e 3,35 (±1,19) cm nas primíparas e multíparas. A prevalência da DMRA supra-umbilical foi 74,8% e 76,6% e, infra-umbilical 40,0% e 54,5%. Nos dois grupos observou-se correlação positiva da distância entre os MRA supraumbilical com idade materna, IMC e infra-umbilical. O IMC e peso do RN foram fatores associados à DMRA supra-umbilical na primíparas e a idade materna nas multíparas. Conclusões: independente da paridade, a distância entre os MRA e prevalência da DMRA foram maiores na região supra-umbilical e, correlacionou-se com idade materna, IMC e infra-umbilical. Nas primíparas os fatores associados foram IMC e peso do RN e nas multíparas, a idade materna.

Objectives: to determine the prevalence of endothelial dysfunction and its association with a history of mild and severe preeclampsia in adolescents. Methods: a cross-sectional study was carried out at the MEAC-UFC with 103 primiparous adolescents postpartum. The assessment of endothelial function was performed by way of flow-mediated dilatation of the brachial artery. Variables (age, body mass index, gestational age at delivery, systolic and diastolic blood pressure and flow-mediated dilation) were compared between groups. p<0.05 was considered to be statistically significant. Results: twenty-four (23.3%) patients had preeclampsia (PE): 11 mild and 13 severe. The overall prevalence of endothelial dysfunction was 23.3% (21.5% of patients with normotensive pregnancies and 29.2% of the PE patients: 18.2% of those with mild PE and 38.5% of those with severe PE). The figures were statistically significant for systolic blood pressure, p=0.007. Conclusions: patients with a history of PE have higher systolic blood pressure than patients with a history of normotensive pregnancy, but did not have more endothelial dysfunction.
How does the Taquari River influence in the cladoceran assemblages in three oxbow lakes?
Authors: Panarelli EA. , Güntzel AM. , Borges CN.
Published: April 2014

This study examined the cladoceran assemblages in three oxbow lakes of the Taquari River floodplain, near the transition between the plateau and the plain. We sought to answer the following questions: does the Taquari River function as a geographical barrier or dispersal corridor for Cladocera? Can different degrees of connection induce different structures in the assemblages in each lake? Cladocerans and limnological variables were sampled every other month for one year. Forty-one species were recorded, four of which were common to all the lakes. Our results indicated that the different degrees of connection between the river and the oxbow lakes favoured environmental heterogeneity and diversification in the cladoceran assemblages. The greatest dissimilarity between the two lakes connected with the river indicates that in this case the river functions better as a barrier than a dispersal corridor.

Published: April 2014

The objective of this study was to evaluate the effect of Oreochromis niloticus cage culture promoted variations in the δ13C and δ15N in Corbicula fluminea (Mollusca; Bivalvia) and in the sediment of an aquatic food web. Samples were taken before and after net cage installation in the Rosana Reservoir (Paranapanema River, PR-SP). Samples of specimens of the bivalve filterer C. fluminea and samples of sediment were collected using a modified Petersen grab. All samples were dried in an oven (60 °C) for 72 hours, macerated to obtain homogenous fine powders and sent for carbon (δ13C) and nitrogen (δ15N) isotopic value analysis in a mass spectrometer. There were significant differences in the δ13C and δ15N values of the invertebrate C. fluminea between the beginning and the end of the experiment. There were no differences between the δ13C and δ15N values of sediment. These results indicate that the installation of fish cage culture promoted impacts in the isotopic composition of the aquatic food web organisms, which could exert influence over the native species and the ecosystem.
