Authors: Akpan Harry Thomas , Edet Etuk Sunday , Namdie Joseph Inyang , Emeka Austin Okoli
Published: November 2018

Evaluation of elastic parameters of reservoirs can be used in geomechanical modelling, wellbore stability analysis, and sanding, which can be applied in practical situation to optimize drilling, completion and productions of wells. Petrophysical analysis was done to identify various reservoirs in two wells, using sonic, neutron, gamma, resistivity and density logs. Porosity, Lithology and Water/Hydrocarbon saturation were determined. The lithology are mostly sand, shale and sandstone with sand/sandstone been the main lithology found in the reservoirs. Porosities in the two wells decreases with depth except in few cases, due to over pressured zones, caused by fluid contents. The reservoirs identified in the two wells are of economic importance due to their net pay zone ranging from 7.16m to 225.25m, with 1067m to 3507m depth, which is within the Agbada formation, having a minimum an average hydrocarbon saturation of 50%. Elastic parameters evaluated are Vs, Vp, Vp/Vs, Poisson ratio, Shear Impedance, Acoustic Impedance, Bulk Modulus, Shear Modulus and Young Modulus. Vp/Vs and Poisson ratio was used to also infer and confirm the lithology gotten from gamma log and also used to discriminate between, oil sand, gas sand and brine sand. The Elastic properties of the reservoirs that are found mostly in the sandstone lithology varies between 15437.91 to 31522.28psi, 7.10 to 24.78Kbar, 5929.51 to 22339.26psi, 1.94 to 18.06Kbar, 1.70 to 2.31, 5.34 to 43.59psi of Acoustic Impedance, Bulk Modulus, Shear Impedance, Shear Modulus, Velocity ratio and Young Modulus respectively.
The effectiveness of platelet concentrations in periodontal surgeries
Authors: Al-Azem Ronad , Ali Neveen , Mostafa Diana
Published: November 2018

Platelets release several growth factors which stimulate tissue regeneration. Several techniques for platelet concentrates such as platelet rich plasma (PRP), plasma rich in growth factors (PRGF), platelet rich fibrin (PRF) and concentrated growth factors (CGF) have been introduced in dental surgeries for the prevention of hemorrhage and acceleration of tissue regeneration. However, a fabricating growth factors-enriched bone graft matrix which is called â€œsticky boneâ€ has been demonstrated to provide stabilization in bony defects. In this article, we presented the method of preparing and utilizing CGF and sticky bone and evaluate the effect of CGF mixed with bone graft and CGF barrier membrane in periodontal surgeries.Methodology: We used websites such as PubMed, Scopus, and ISI Web of knowledge to get related articles about this subject. The research process involved specific key words " concentrated growth factorâ€- â€œPlatelet rich fibrinâ€- growth factors-enriched bone graftâ€ - â€œsticky boneâ€ to find more articles which published from 2007 to March 2018.Results: We reviewed 48 articles, 43 articles were excluded. Only five articles have been conducted. Original human studies and case report were included.Conclusion: We concluded that the use of sticky bone and CGF is effective in bone grafting and implant.Â Â
Framing the Romantic Artist: Goethe’s Torquato Tasso and James’s Roderick Hudson
Authors: Müller Timo
Published: November 2018

Johann Wolfgang Goethe’s Torquato Tasso (1790) and Henry James’s Roderick Hudson (1875) share not only a number of structural parallels but also an interest in the fate of the romantic artist in a regulated society. The article suggests Goethe’s play as a possible influence on James’s novel. After a brief outline of James’s relationship to Goethe and of the structural parallels between the texts, the article discusses the similarities of their stance on the romantic artist. Both texts contrast the protagonist’s classicist-idealist art with his broadly romantic personality, both remain ambivalent about the romantic conception of the poet-genius, and both take an analytical attitude toward their artist figures. On this poetological level, the article concludes, their portraits of a proto-Romantic and a late Romantic respectively form a revealing historical frame of the phenomenon of the Romantic artist.
“The sad, proud old man stared eternally out of his canvas...”: Media Criticism, Scopic Regimes and the Function of Rembrandt’s “Self-Portrait with Two Circles” in John Fowles’s Novel Daniel Martin
Authors: Horlacher Stefan
Published: November 2018

On the surface level, Fowles’s novel sets the trust in the timelessness of art and the possibility of a recourse to some kind of ‘true self’ against American hyperreality. Though the novel’s verdict on the American scopic regime of simulacra is devastating, England’s morbid theatricality does not represent an alternative. However, a novel which criticizes visuality only to accord Rembrandt’s “Self-Portrait” a place of utmost importance necessarily runs into problems of self-contradiction: Rembrandt’s self-portrait refuses any one-dimensional functionalization and contains self-reflexive/revocative elements pertaining to its capitalist dimension and to the dangers of commodification/narcissism/serialization. Moreover, Rembrandt’s portrait is located at the centre of a whole series of mises en abyme and contains significant autotelic elements which link it with the criticized American scopic regime, question its representational dimension by stressing the pure materiality of the work of paint and revoke Fowles’s novel and its didactic media-theoretical underpinnings.

I would like to thank Bryan Knowlton, Simon Loesch, Keith Hollingsworth and Bettina Jansen for their constructive help at various stages of work on this article.
Would a Basic Income Guarantee Reduce the Motivation to Work? An Analysis of Labor Responses in 16 Trial Programs
Authors: Gilbert Richard , Murphy Nora A. , Stepka Allison , Barrett Mark , Worku Dianne
Published: November 2018

Many opponents of BIG programs believe that receiving guaranteed subsistence income would act as a strong disincentive to work. In contrast, various areas of empirical research in psychology (studies of intrinsic motivation; non-pecuniary benefits of work on social identity and purpose; and reactions to financial windfalls such as lottery winnings) suggest that a BIG would not lead to meaningful reductions in work. To test these competing predictions, a comprehensive review of BIG outcome studies reporting data on adult labor responses was conducted. The results indicate that 93 % of reported outcomes support the prediction of no meaningful work reductions when the criterion for support is set at less than a 5 % decrease in either average hours worked per week or the rate of labor participation. Overall, these results indicate that adult labor responses would show no substantial impact following a BIG intervention.
The impact of steatosis on liver regeneration
Authors: Allaire Manon , Gilgenkrantz Hélène
Published: November 2018

Alcoholic and non-alcoholic fatty liver diseases are the leading causes of cirrhosis in Western countries. These chronic liver diseases share common pathological features ranging from steatosis to steatohepatitis. Fatty liver is associated with primary liver graft dysfunction, a higher incidence of complications/mortality after surgery, in correlation with impaired liver regeneration. Liver regeneration is a multistep process including a priming phase under the control of cytokines followed by a growth factor receptor activation phase leading to hepatocyte proliferation. This process ends when the initial liver mass is restored. Deficiency in epidermal growth factor receptor (EGFR) liver expression, reduced expression of Wee1 and Myt1 kinases, oxidative stress and alteration in hepatocyte macroautophagy have been identified as mechanisms involved in the defective regeneration of fatty livers. Besides the mechanisms, we will also discuss in this review various treatments that have been investigated in the reversal of the regeneration defect, for example, omega-3 fatty acids, pioglitazone, fibroblast growth factor (FGF)19-based chimeric molecule or growth hormone (GH). Since dysbiosis impedes liver regeneration, targeting microbiota could also be an interesting therapeutic approach.
Optimal Thrust Programming Along the Brachistochronic Trajectory with Non-linear Drag
Authors: Cherkasov Oleg , Zarodnyuk Alena , Smirnova Nina
Published: November 2018

The problem of maximization of the horizontal coordinate of a mass-point moving in the vertical plane driven by gravity, non-linear viscous drag, and thrust is considered. The slope angle and the thrust are considered as a control variables. The problem is related to the modified brachistochrone problem. Principle maximum procedure allows to reduce the optimal control problem to the boundary value problem for a set of systems of two non-linear differential equations. The qualitative analysis of the trajectories of these systems is performed, and the characteristic features of the optimal solutions are determined. Thrust control depending on the velocity and slope angle is designed. Results obtained allow to construct quasi-optimal solutions for the more complex systems, where phase plane method is not applicable.

are a standard assumption in the theory of inverse problems to show convergence rates of regularized solutions as the noise in the data goes to zero. Unfortunately, it is rarely possible to verify these conditions in practice, rendering data-independent parameter choice rules unfeasible. In this paper we show that such a source condition implies a Kurdyka–Łojasiewicz inequality with certain parameters depending on μ. While the converse implication is unclear from a theoretical point of view, we propose an algorithm which represents a first attempt that allows to approximate the value of μ numerically. It is based on combining the Landweber iteration with the Kurdyka–Łojasiewicz inequality. We conduct several numerical experiments to demonstrate the potential and limitations of the current method. We also show that the source condition implies a lower bound on the convergence rate which is of optimal order and observable without the knowledge of μ.

Discourse-pragmatic functions of the present perfect in American English TV and radio interviews
Authors: Frazier Stefan , Koo Hahn
Published: November 2018

The English present perfect has received a great deal of sentence-based analytical attention in the empirical linguistic literature as well as some corpus-based coverage at the discourse level, in which analysis depends on close scrutiny of the context of a structure’s placement, i.e. several utterances, turns at talk, or sentences before and after. Due to the painstaking nature of such analysis, however, corpora used to date have been relatively small. This study, via a corpus of over 12 million words from television and radio interviews in the United States, categorizes the use of discourse-pragmatic functions of 268 present perfect tokens. From this analysis, one use stood out overwhelmingly: the present perfect in the employment of position-taking or support. Also, only very rarely was the present perfect used to initiate narratives, which is a finding that does not conform to previous understandings. The study contributes to the overall knowledge of present perfect use and has implications for how the tense can be taught to English language learners.
Optimization of Hot Workability and Control of Microstructure in 18Ni (M250 Grade) Maraging Steel Using Processing Maps
Authors: Chakravarthi K. V. A. , Koundinya N. T. B. N. , Sarkar Aditya , Narayana Murty S. V. S. , Nageswara Rao B.
Published: November 2018

This article examines the hot working characteristics of M250 grade maraging steel by performing isothermal compression tests varying the temperatures and strain rates. A processing map has been developed, indicating microstructurally “stable” and “unstable” regions during hot working. At strain rates (ϵ˙) above 0.1 s−1 and temperatures (T) below 1,000°C, stress–strain curves show strain hardening behavior, whereas steady-state behavior is shown at strain rates below 0.01 s−1 and temperatures above 1,050°C. Above 1,150°C, flow softening is observed at 0.001 and 0.01 s−1. In the processing map, two distinct microstructurally stable domains are observed: one is at T = 1,150–1,200°C and ϵ˙ = 0.001–0.01 s−1, and another is at T = 1,000–1,150°C and ϵ˙ = 0.001–0.1 s−1. Based on microstructural observations, electron backscattered diffraction results, and the high efficiency of power dissipation, dynamic recrystallization is the softening mechanism. A constitutive relation useful in computer modeling is developed, using the generated flow stress data.

Directing Voluntary Temporal Attention Increases Fixational Stability
Authors: Denison Rachel N. , Yuval-Greenberg Shlomit , Carrasco Marisa
Published: November 2018

Our visual input is constantly changing, but not all moments are equally relevant. Visual temporal attention, the prioritization of visual information at specific points in time, increases perceptual sensitivity at behaviorally relevant times. The dynamic processes underlying this increase are unclear. During fixation, humans make small eye movements called microsaccades, and inhibiting microsaccades improves perception of brief stimuli. Here, we investigated whether temporal attention changes the pattern of microsaccades in anticipation of brief stimuli. Human observers (female and male) judged stimuli presented within a short sequence. Observers were given either an informative precue to attend to one of the stimuli, which was likely to be probed, or an uninformative (neutral) precue. We found strong microsaccadic inhibition before the stimulus sequence, likely due to its predictable onset. Critically, this anticipatory inhibition was stronger when the first target in the sequence (T1) was precued (task-relevant) than when the precue was uninformative. Moreover, the timing of the last microsaccade before T1 and the first microsaccade after T1 shifted such that both occurred earlier when T1 was precued than when the precue was uninformative. Finally, the timing of the nearest pre- and post-T1 microsaccades affected task performance. Directing voluntary temporal attention therefore affects microsaccades, helping to stabilize fixation at the most relevant moments over and above the effect of predictability. Just as saccading to a relevant stimulus can be an overt correlate of the allocation of spatial attention, precisely timed gaze stabilization can be an overt correlate of the allocation of temporal attention.

SIGNIFICANCE STATEMENTWe pay attention at moments in time when a relevant event is likely to occur. Such temporal attention improves our visual perception, but how it does so is not well understood. Here, we discovered a new behavioral correlate of voluntary, or goal-directed, temporal attention. We found that the pattern of small fixational eye movements called microsaccades changes around behaviorally relevant moments in a way that stabilizes the position of the eyes. Microsaccades during a brief visual stimulus can impair perception of that stimulus. Therefore, such fixation stabilization may contribute to the improvement of visual perception at attended times. This link suggests that, in addition to cortical areas, subcortical areas mediating eye movements may be recruited with temporal attention.
Restoring our senses, restoring the Earth. Fostering imaginative capacities through the arts for envisioning climate transformations
Authors: Galafassi Diego , Tàbara J. David , Heras María
Published: November 2018

Humanity has never lived in a world of global average temperature above two degrees of current levels. Moving towards such High-End Climate Change (HECC) futures presents fundamental challenges to current governance structures and involves the need to confront high uncertainties, non-linear dynamics and multiple irreversibilities in global social-ecological systems. In order to face HECC, imaginative practices able to support multiple ways of learning about and experiencing the future are necessary. In this article we analysed a set of arts-based activities conducted within the five-year EU-funded project IMPRESSIONS aimed at identifying transformative strategies to high-end climate change. The exploratory artistic activities were carried out alongside a science-led participatory integrated assessment process with stakeholders from the Iberian Peninsula. Our arts-based approach combined a range of performative, visual and reflexive practices with the ambition to reach out to more-than-rational but also practical elements of HECC futures. Our study suggests that the arts-based approach helped to bring out new ways of seeing, feeling and interpreting the world which may support the development of individual and collective sensibilities needed to address HECC.
Maternal Food Memories in Lin Cheng-sheng's 27°C: Loaf Rock and Eric Khoo's Recipe: A Film on Dementia
Authors: Bloom Michelle E.
Published: November 2018

Elderly mothers pick pineapple in Taiwanese fields and cook curry rice in a Singaporean hawker stand in Lin Cheng-sheng's biopic, 27°C: Loaf Rock, and Eric Khoo's telefilm, Recipe: A Film on Dementia, respectively. Both 2013 Chinese language films employ flashbacks to portray maternal food memories. Lin and Khoo depict food as comforting and possessing a unique ability to stimulate long-term memory to counter the short-term memory loss symptomatic of this form of dementia. The gustatory and the olfactory act directly upon the limbic brain, which houses emotions. In depicting Alzheimer's sufferers and their responses to food, 27°C and Recipe fight for causes. Lin calls attention to the marginalized in his portrayal of the mother succumbing to the disease from the perspective of her son—a character based on contemporary Taiwanese baker Wu Pao-chun, who overcame the adversity of impoverishment to win the world famous Master's de la Boulangerie and found prestigious eponymous bakeries. Parallel to its role in individual memory, food preserves cultural memory. Analogous to culinary arts, cinema, which is made for consumption, combines art and science, embodies culture, and incorporates tradition and innovation, as I show in this comparative study.
When the Kids Conquered the Kitchen: Danish Taste Education and the New Nordic Kitchen
Authors: Wistoft Karen , Qvortrup Lars
Published: November 2018

The New Nordic Kitchen has conquered the world, Agern and the Nordic Food Hall at Grand Central Station in New York City and Noma in Copenhagen serving as notable examples. Normally this development is perceived as something that came out of nowhere, or as the result of the initiatives of specific individuals such as René Redzepi, chef at Noma. In this article, we will argue that it is part of a much broader cultural movement replacing precision, nutrition, and hygiene with pleasure, taste, and creativity as the center of kitchen culture, food education, and child upbringing. We support this argument by focusing on children's cookbooks published in Denmark during the period 1971–2016.

Published: November 2018

In this paper, we introduce the notion of ultra distance function. Based on the notion of ultra distance function, we introduce the definitions of (k, ψ, L)-quasi contractions of type (I) and type (II) in the frame of quasi metric spaces. We employ our new definitions to construct and prove many fixed and common fixed point results in the frame of quasi metric spaces. Our results extend and improve many exciting results in the literatures. Also, we introduce some examples and some applications in order to support the usability of our work.
Food safety aspect of insects: A review
Authors: Mézes M.
Published: November 2018

Insects are alternative protein sources as nutritious novel food. However, there are some risks associated with the consumption of insects, even if rearing in controlled systems. Except for a recent EFSA opinion on the safety of insects as food, the European law is not conclusive regarding using insects as food products. Insects may be associated with microorganisms, but the prevalence of pathogens is usually lower than in case of other animal proteins. Insect proteins can induce allergic reactions, but only few studies are available on allergic reactions due to insect ingestion, and direct hypersensitivity to insect protein has not been proven. Some insect species are considered toxic, because some toxic substances are accumulated from toxic plants or are synthesized by the insects. However, there are few reports available about adverse reactions caused by insect consumption. Insects and insect derived food products may contain hazardous chemicals such as heavy metals, dioxins, mycotoxins, plant toxins, biocides, and veterinary drugs. However, data on hazardous chemicals in reared insects and accumulation of chemical contaminants from the substrates are limited. This review is not demonstrating the safety of insects as a food category, but the possibility of insects for human consumption with no more hazards than other animal products.
Optimization of spray-drying process for concentrated orange juice
Authors: Pino J.A. , Aragüez-Fortes Y. , Bringas-Lantigua M.
Published: November 2018

Response surface methodology was used to optimize spray-drying process for concentrated orange juice. Independent variables were: inlet air temperature (130–170 ºC) and maltodextrin 12DE content (60–75% wet basis (wb)). Responses variables were powder yield, moisture, and ascorbic acid retention. Moisture content was negatively affected by inlet air temperature, while ascorbic acid retention was directly related. Powder yield and ascorbic acid retention increased with the rise in maltodextrin content, while moisture content was negatively affected by maltodextrin content. Multiple response optimisation indicated that an inlet air temperature of 155 ºC and maltodextrin content of 74% wb were predicted to provide 77% powder yield, 3.7% wb moisture content, and 89% ascorbic acid retention.

Resumo: O processo de doação e transplante hepático no Brasil revela grandes desigualdades entre regiões e Unidades da Federação, desde a captação de órgãos até o implante do fígado. Em 2006, o escore MELD (Model for End-stage Liver Disease), inspirado no modelo estadunidense e baseado no princípio da necessidade, foi introduzido no Brasil para a alocação de fígado. Porém, as desigualdades no nosso país têm comprometido, parcialmente, o sucesso dessa iniciativa. Em outros países, já se presencia uma crescente discussão sobre o benefício de modelos que tentam harmonizar utilitarismo e necessidade. O presente artigo revisa a literatura pertinente com um foco especial na realidade brasileira.

Authors: Souza Marília Silva de , Araújo Jaciana Marlova Gonçalves , Souza Luciano Dias de Mattos
Published: November 2018

Abstract Smoking accounts for 24% of deaths in the general population and is also the factor that explains the biggest amount of years of life lost. It is important to understand the expectations regarding smoking behavior. The present study aimed to validate the Short Form of the Smoking Consequences Questionnaire (S-SCQ) for a Brazilian version. The Researchers did the process of semantic adaptation to language and national context. The S-SCQ was applied in a sample of 129 people. The next step was to perform psychometric analyses for the set of 21 items. Exploratory Factor Analysis, with pairwise treatment for missing cases, was used to achieve construct validity. To carry out Factor Analysis, the method of Principal Component Analysis (PCA) was used initially. Afterwards, Principal Axis Factoring (PAF) using Varimax rotation with Kaiser normalization was applied. The reliability of the total scale (21 items) showed a Cronbach alpha index of 0.851 and a 0.870 Lambda2 of Gutmann. Quite satisfactory rates were also observed in the subscales. Similarly, the item-overall correlation values also confirmed the scale’s good reliability indices.

Resumo A amamentação é uma prática diretamente relacionada com a saúde da mãe e, principalmente, do bebê. Apesar de ser um processo natural, muitas mães relatam dificuldades. Este estudo objetivou buscar evidências científicas sobre a questão: “Mãe com mais confiança consegue amamentar exclusivamente por 6 meses?”. Foi realizada uma revisão sistemática com busca em 5 bancos de dados eletrônicos, que resultou na inclusão de 4 estudos de coorte para avaliação. Realizou-se uma análise qualitativa dos resultados, porém não foi possível fazer a meta-análise. Autoconfiança em amamentar foi avaliada pela escala “Breastfeeding Self-Efficacy Scale”. Os estudos analisados mostraram que há associação estatística significante entre aleitamento materno exclusivo e autoconfiança em amamentar. A utilização da escala parece ser uma ferramenta confiável para identificar mães em risco para desmame precoce, facilitando o planejamento de ações pelos profissionais em saúde. As evidências obtidas mostraram a associação entre mães com maior confiança em amamentar e a amamentação exclusiva por 6 meses, porém estes resultados não podem ser generalizados devido à heterogeneidade das populações.

Published: November 2018

Resumo Águas contaminadas representam um risco à saúde não somente pelo consumo direto, mas também pelo uso recreativo. Estratégias de análise de risco visam à redução dos casos de contaminação e devem incorporar as percepções e aceitação das pessoas em assumir riscos. Um método rápido e simplificado foi desenvolvido para avaliar a probabilidade do uso de águas recreativas. Foram realizadas entrevistas em municípios com condições ecológicas distintas, para elencar fatores que embasam a decisão das pessoas pelo uso dos rios. Em seguida, foi elaborado e realizado pré-teste do Índice de Probabilidade de Uso Recreativo de Águas (I-PURA) que, após ajuste, foi aplicado em 26 balneários de 5 das 9 regiões hidrográficas do estado do Rio de Janeiro. Foram medidas, ainda, a frequência de uso, a contaminação bacteriana da água e um índice de avaliação do habitat (IAH). O I-PURA foi correlacionado à frequência de uso, mas não com o IAH, evidenciando que a percepção dos usuários é diferente de aspectos puramente ecológicos. Este método contribui com a análise de risco e manejo dos recursos hídricos. Locais em que há alta probabilidade de uso, ou uso observado, e alta contaminação são estratégicos para intervenção.

Resumo O objetivo deste estudo foi analisar a reprodutibilidade “teste-reteste” de um questionário de Atividade Física em 1.189 escolares, de ambos os sexos, de 9 a 15 anos da rede pública de ensino de Curitiba/PR. A reprodutibilidade do questionário foi determinada pelo procedimento de medidas repetidas “teste-reteste” com uma semana de intervalo entre as aplicações. Para a análise dos dados utilizou-se o Coeficiente de Correlação Intraclasse (CCI), o percentual de concordância, o índice Kappa, o Kappa ajustado (Kappa PABAK) e o diagrama de dispersão de Bland-Altman. As análises estatísticas foram efetuadas no SPSS 21.0 adotando-se um nível de significância de 5%. Todos os CCI foram superiores a 0,80. A concordância entre as réplicas de aplicação do questionário foi moderada, Kappa variando de 0,51 a 0,61. Verificou-se concordância entre as réplicas de aplicação do questionário, sendo a diferença média entre a primeira e a segunda igual a 106,49 min/semana (IC95%: 79,05-133,92) com limites de concordância variando de 1.070,97 (+2DP) a -857,99 (-2DP) min/semana. Conclui-se que o questionário analisado neste estudo apresentou níveis satisfatórios de reprodutibilidade podendo ser utilizado para mensurar a atividade física tanto em crianças quanto em adolescentes.

Resumo O objetivo deste artigo é avaliar a prevalência e os fatores associados à ausência de aleitamento materno na alta hospitalar em uma maternidade pública de Maceió, Alagoas, Brasil. Estudo transversal realizado com puérperas sob alta hospitalar assistidas na maternidade do hospital universitário da capital. Foram calculadas razões de prevalência (RP) e respectivos intervalos de confiança de 95% (IC95%) por regressão de Poisson com emprego de modelo hierarquizado. Aproximadamente 20% das puérperas não estavam amamentando. Hábito tabagista na gravidez [RP = 5,20; (IC95% = 1,75-15,33); p = 0,003]; intercorrências na gestação [RP = 3,50; (IC95% = 1,04-11,77); p = 0,042] e falta de informações sobre aleitamento materno no pré-natal [RP = 5,44; (IC95% = 1,78-16,67); p = 0,003] foram fatores desfavoráveis à amamentação. A prática de aleitamento materno dentro da maternidade está aquém do ideal. Evidencia-se a importância do pré-natal, visando fornecer orientações quanto à prevenção do tabagismo na gestação e aconselhamento sobre aleitamento materno, com atenção especial àquelas puérperas que tiveram intercorrências na gestação.

Resumo Reações adversas a medicamentos (RAM) podem ser causa de enfermidades, incapacidades ou óbitos, principalmente em idosos. Realizou-se busca ativa de suspeitas de RAM que motivaram a procura de idosos por cuidados em pronto socorro (PS) utilizando rastreadores e discutindo seu uso nessa unidade de atendimento. Tratou-se de um estudo transversal e retrospectivo que utilizou adaptação dos rastreadores do “Institute of Healthcare Improvement”. Foram analisados 287 prontuários, nos quais foram encontrados 38 rastreadores que identificaram 7 suspeitas de RAM. Uma foi encontrada sem uso dos rastreadores. Assim, no total, foram encontradas 8 reações (2,79%). Os medicamentos mais implicados foram os para trato alimentar e metabolismo e sistema cardiovascular. Dos rastreadores testados, alguns são essenciais para uso em PS, como os que indicam problemas com anticoagulantes, hipoglicemiantes e anti-hipertensivos, medicamentos bastante utilizados por idosos. Outros são adequados a estudos prospectivos, por necessitarem avaliação detalhada para confirmar da suspeita de RAM. Os rastreadores devem ser adaptados para cada instituição, mas se mostraram úteis para a detecção das suspeitas de RAM, identificando problemas ocorridos fora do ambiente hospitalar e sinalizando medicamentos que envolvem maior risco ao paciente idoso.

Abstract The potential of the reflective collective portfolio as a method of teaching, learning and assessment needs to be emphasized. The objectives is to assess and validate the quality of the collective portfolio as a method of teaching, learning and assessment in the training of health professional. Portfolio quality was analyzed using an inventory of analysis that was adapted and tested for this study. In total, 70 portfolios were analyzed. The Kappa test was used to analyze reproducibility, confirming the level of agreement between the appraisers. Descriptive analysis and the t-test were performed to compare results from the years the portfolios were produced. The constructs (layout and organization, comprehensive, reflective, critical and creative thought) exhibited Cronbach alpha values above 0.7, confirming the high reliability of the tool. The weighted Kappa test revealed an elevated and significant agreement (+90%) between the appraisers. Notably, certain items and constructs exhibited significant differences over the years. All of the constructs were assessed better from 2011 onwards, when the assessment and self-assessment tool was implemented. The success of the portfolio depends on strategies that provide students with greater clarity and forms of developing the method.

Published: November 2018

Resumo O objetivo deste estudo foi discutir as estratégias pedagógicas destinadas às mulheres para institucionalização da representação do parto normal a partir da obra Parto Natural: Guia para os futuros pais, publicada em 1955. Partiu-se de uma análise histórica e cultural desse livro em suas edições publicadas nos anos de 1955, 1957, 1960 e 1964, auxiliada por materiais publicados à época que compartilhavam das mesmas significações e representações referentes às questões do parto no contexto brasileiro. Esse período foi marcado pelo resgate e surgimento de métodos de preparação da mulher para o processo de parir. A análise, à luz do referencial teórico de Roger Chartier, principalmente com a noção de representação, e de Michel Foucault, indica que os dispositivos utilizados na tessitura da obra visaram propor um modelo de parto disciplinar, a institucionalização, medicalização e industrialização do parto normal no contexto brasileiro em meados do século XX.

Resumo A prevalência da simultaneidade de doenças específicas nos idosos ainda é pouco descrita na literatura. O objetivo do estudo foi estimar a prevalência simultânea de hipertensão arterial e diabetes mellitus em idosos brasileiros, e os fatores contextuais e individuais a ela associados. Estudo transversal de base populacional com idosos (≥ 60 anos) entrevistados pelo Vigitel em 2012 (n = 10.991). As análises foram realizadas por meio de regressão de Poisson multinível no Stata 12. A média de idade dos idosos foi de 69,4 anos e a prevalência simultânea das doenças foi de 16,2% com variação nas capitais brasileiras. Em São Paulo e Curitiba as prevalências foram mais elevadas do que em Boa Vista e Manaus. Maiores prevalências foram observadas nas capitais das regiões Sul/Sudeste/Centro-Oeste, nos idosos de cor preta e parda, naqueles com escolaridade ≤ 8 anos de estudo, nos não fumantes e ex-fumantes, e com excesso de peso. Verificou-se o efeito da região geográfica na prevalência simultânea pela elevação de 23,5% na magnitude da razão de prevalencia, após ajuste para todas as variáveis individuais. Por meio do estudo, foi possível dimensionar o efeito do contexto onde estão inseridos os idosos (região de residência) sobre a prevalência das principais doenças que acometem e relacionam-se à mortalidade na população idosa na atualidade.

Published: November 2018

Resumo O câncer do colo do útero é o terceiro tumor mais frequente na população feminina e o teste citopatológico (CP) a principal estratégia para o rastreamento. Este estudo mediu a prevalência e os fatores associados à não realização de CP entre gestantes maiores de 25 anos, durante o pré-natal, no município de Rio Grande, RS, em 2013. A análise multivariável utilizou regressão de Poisson avaliada por meio de razão de prevalências (RP). Dentre as 1474 gestantes incluídas no estudo, 21,6% (IC95% 19,5%-23,7%) não realizaram CP nos últimos três anos. Na análise ajustada, a RP para não realização entre puérperas com escolaridade entre 0-4 anos foi 2,14 (IC95%:1,35-3,38) em comparação àquelas com 12 anos ou mais. Ter referido aborto prévio e consumido álcool durante a gestação mostrou RP = 1,38 (1,10-1,73) e 1,39 (1,04-1,84) de não fazê-lo em relação às demais, respectivamente. Realizar 1-5 consultas de pré-natal conferiu RP = 1,35 (1,03-1,77) em relação às demais. Evidencia-se proporção expressiva de não realização de CP e não cumprimento de recomendação básica do Ministério da Saúde. Os profissionais de saúde deveriam reforçar a necessidade de realização deste exame, bem como busca ativa na comunidade das gestantes com o perfil aqui descrito.
