Published: November 2018

RESUMO Objetivo: Analisar a influência da diluição, o tempo e a temperatura pós-preparo na osmolalidade das fórmulas lácteas oferecidas a recém-nascidos (RN). Métodos: Estudo experimental e descritivo com uma amostra de diferentes fórmulas lácteas neonatais para verificar a osmolalidade do leite segundo a diluição, o tempo e a temperatura pós-preparo. Foram analisadas sete fórmulas lácteas neonatais nos seguintes tempos: imediatamente (até 5 minutos) após o preparo; 20 e 40 minutos após o preparo; de hora em hora, até completar 8 h; e após 12 e 24 h de preparo. As amostras foram avaliadas após o preparo em temperatura ambiente e depois da refrigeração. Foram elaboradas curvas de osmolalidade com a média das triplicatas de cada amostra de leite. O cálculo da osmolalidade foi aferido no Osmômetro digital A+ da Advanced Instruments, modelo 3.320. Resultados: O tempo e a temperatura em que os leites ficaram submetidos após o preparo não ultrapassaram o ponto de corte de segurança da osmolalidade na diluição 1:30 em nenhum dos tipos de leite analisados. Na diluição 1:25 a fórmula láctea que possui prebióticos em sua composição ultrapassou o limite após 4 h de preparo. Conclusões: Os leites testados não ultrapassaram o ponto de corte de 450 mOsm/kg (aproximadamente 400 mOsm/L), indicado como seguro pela Academia Americana de Pediatria (AAP) na diluição preconizada pelos fabricantes. É necessário conhecer os fatores que podem ou não contribuir com o aumento da osmolalidade, afim de se estabelecer condutas seguras e de qualidade para os RN, seguindo protocolos baseados em evidências científicas.
O mercado habitacional e o processo de gentrificação em cidades latino-americanas: um estudo exploratório no bairro de Boa Viagem, Recife-PE
Authors: Leão Júnior Fernando Pontual de Souza , Brito Cristóvão de Souza
Published: November 2018

Resumo O espaço da cidade é o lócus de ação dos agentes do mercado imobiliário habitacional, e suas ações são indutoras do processo de diferenciação demográfica nas cidades. A ideia de que a ação do mercado estabelece uma nova lógica de ocupação urbana é o objeto da análise realizada neste trabalho, o qual pretende compreender a relação entre a ação do mercado habitacional no município de Recife-PE e o processo de gentrificação decorrente dela. Foi realizado um estudo de caso no bairro Boa Viagem, principal foco de atuação do mercado habitacional formal. O trabalho é de natureza descritiva e utiliza uma modelagem estatística de regressão linear para estabelecer um entendimento conciso acerca da relação entre algumas variáveis demográficas do bairro e a ação do mercado habitacional. Os resultados indicaram que houve um gradativo processo de elevação das variáveis socioeconômicas nos bairros, a qual foi superior ao mesmo processo nos bairros onde a ação do mercado foi menor ou inexistente. A hipótese de que a ação do mercado habitacional estabelece um processo de segmentação e diferenciação demográfico-espacial foi confirmada, denotando a ocorrência de mudança imobiliária e o consequente processo de gentrificação.
Nietzsche, filho de seu tempo: a questão do ascetismo
Authors: Binoche Bertrand
Published: November 2018

Resumo O presente artigo tem por objetivo examinar de que forma o contexto histórico-filosófico do século XIX influenciou a compreensão nietzschiana acerca do ascetismo. Para tanto, foi necessário se afastar da obra de Nietzsche e levar a cabo uma pesquisa de ordem filológica em textos filosóficos que tratavam do tema no referido século, a qual trouxe à baila a hipótese de que o termo "ascetismo" - apesar de possuir raízes doutrinárias, conceituais e etimológicas na antiguidade e na idade média - surge nos textos da filosofia europeia apenas no século XIX. Ao longo da argumentação também se evidencia como a interpretação e o uso utilitarista da noção de ascetismo foi essencial para a elaboração da crítica nietzschiana ao ideal e às práticas ascéticas.

Published: November 2018

Resumo Este ensaio tem como objetivo refletir acerca de contribuições teórico-metodológicas que possibilitaram a composição de uma “caixa de ferramentas” para o desenvolvimento de pesquisas e intervenções nos mundos do trabalho articuladas a estratégias de formação de trabalhadores. Inicialmente, coube destacar a influência do patrimônio construído no Brasil pelos movimentos de educação popular e da saúde do trabalhador, que preconizam uma cooperação crítica entre intelectuais e trabalhadores visando à transformação das situações de vida e trabalho. Nessa direção, mostrou-se fundamental a incorporação do “ponto de vista da atividade” e a proposição do dispositivo Comunidade Ampliada de Pesquisa e Intervenção (CAPI), com vistas ao desenvolvimento de práticas de formação que contribuem para a promoção da saúde a partir das situações de trabalho. Tal encaminhamento aposta na produção de meios de análise e de transformação do trabalho conduzidos pelos próprios trabalhadores (desenvolvendo sua capacidade investigativa), em diálogo com os pesquisadores profissionais. Isso demonstra a valorização de um patrimônio comum de conceitos, mas, principalmente, de uma perspectiva ética e epistemológica segundo a qual a compreensão ↔ transformação das situações de trabalho e a promoção da saúde somente são possíveis por intermédio da sinergia entre os saberes das disciplinas e aqueles investidos na atividade.
Use of Adjuvants to Optimize the Activity of Two Broad-Spectrum Herbicides for Weed Control in Wheat
Authors: ABBAS N. , TANVEER A. , AHMAD T. , AMIN M.
Published: November 2018

ABSTRACT: Herbicide resistance development among weeds, environmental contamination and health concerns due to the overuse of herbicides have led researchers to focus on ways to reduce herbicides to be sprayed for weed management. Adjuvants are best suited for that purpose, as they accomplish a crucial role in achieving satisfactory control of weeds by maximizing herbicidal activity. A two-year field investigation was carried out at the Agronomic Research Area, in the University of Agriculture, in Faisalabad, Pakistan during the winter of 2014 and 2015, with the objective to optimize the activity of two broad-spectrum herbicides at reduced dose (75% of the label mentioned rate) for weed control in wheat. Minimum weed density, weed dry weight and NPK uptake were recorded with reduced dosed mesosulfuron methyl + iodosulfuron methyl sodium at 10.60 g a.i. ha-1 combined with fatty alcohol ethoxylate at 200 mL ha-1. This was followed by reduced dosed sulfosulfuron at 18.75 g a.i. ha-1 combined with the same adjuvant. Among various herbicidal treatments, application of reduced dosed mesosulfuron methyl + iodosulfuron methyl sodium at 10.60 g a.i. ha-1 combined with fatty alcohol ethoxylate at 200 mL ha-1 was proved to be most cost effective and resulted in maximum wheat yield during both years of study.

Nouvelle gestion publique et professions hospitalières
Authors: Belorgey Nicolas
Published: November 2018

Résumé La Nouvelle Gestion Publique (NGP) peut être définie comme un ensemble de pratiques et d’idées visant à importer dans le secteur public les méthodes de travail du secteur privé. Qu’advient-il, dans ce contexte, des agents publics, chargés de mettre en œuvre les politiques publiques, ceux dont les pratiques quotidiennes sont directement visées par cette volonté de transformation ? Pour répondre à cette question, nous utilisons des observations, entretiens et questionnaires réalisés dans le cadre d’une thèse sur les hôpitaux français dans les années 2000. Nous montrons qu’il y a bien différenciation au sein des professions de santé, mais que la NGP se heurte à l’opposition des segments dominants de celles-ci, tandis que les segments dominés composent davantage avec elle notamment parce qu’ils ont moins les moyens de lui résister.
Efeito do envelhecimento acelerado sobre as propriedades de microconcreto reforçado com fibras longas de sisal
Authors: Lima Paulo Roberto Lopes , Toledo Filho Romildo Dias , Neumann Reiner , Barros Joaquim Antonio Oliveira
Published: November 2018

Resumo Neste trabalho dois microconcretos, com e sem metacaulinita, foram dosados para produção de compósitos laminados reforçados com fibras longas de sisal. Para garantir uma matriz livre de hidróxido de cálcio foi determinado o teor ideal de metacaolinita por análise termogravimétrica de pastas com teores de substituição de 20%, 30% e 40 nas idades de 4 h, 10 h, 24 h, 7 dias, 28 dias e 730 dias. Laminados com 30% de metacaolinita foram submetidos a ensaio de flexão após 28 dias de cura em água e após 12 e 25 ciclos de molhagem e secagem. A análise da microestrutura foi realizada a partir de microscopia eletrônica de varredura e espectroscopia de raios X por energia dispersiva (EDS). Os resultados demonstram que, no microconcreto contendo apenas cimento, o hidróxido de cálcio foi lixiviado da matriz e depositado na superfície da fibra, o que resultou em ruptura brusca devido ao enfraquecimento das fibras. Com a adição de metacaolinita, a matriz mostrou-se livre de hidróxido de cálcio, e o comportamento mecânico pós-fissuração não foi alterado pelo envelhecimento. No entanto, a variação de temperatura e umidade do ciclo molhagem-secagem induziu fissuração do microconcreto, o que negativamente afetou a resistência à formação da primeira fissura do compósito e seu modo de ruptura.

Resumo Dentre os fatores envolvidos na fabricação dos painéis destaca-se o tipo adesivo, em que o uso de novos pode resultar em boas propriedades aos materiais fabricados. Nesse contexto, esta pesquisa objetivou avaliar propriedades físicas e mecânicas de painéis de partículas fabricados com madeiras de Pinus sp. e de Eucalyptus grandis e unidas com resina poliuretana monocomponente derivada do óleo de mamona, cujo desenvolvimento desse adesivo vem sendo sistematicamente aperfeiçoado por diversos fabricantes. Foram produzidos dez painéis para cada espécie de madeira, ambos fabricados sobre as mesmas condições experimentais: 640 g de partículas (teor de umidade próximo de 10%), teor de adesivo de 15% sobre a massa de partículas, 10 min de tempo de prensagem a 100 ºC sob pressão de 4,0 MPa, consistindo nos mesmos parâmetros utilizados na fabricação de painéis de partículas de outras pesquisas, mas com o uso da resina bicomponente à base de mamona. Os painéis foram caracterizados segundo premissas e métodos de cálculo da norma brasileira NBR 14810-2 (2013), sendo utilizadas também normas internacionais para a verificação do requisitos. Com exceção da resistência ao arrancamento de parafuso, as demais propriedades obtidas superaram os requisitos dos documentos normativos utilizados.
Efeito da incorporação de resíduo de TiO2 (MNR) na formação das fases mineralógicas de clínquer Portland
Authors: Mariani Bruna Bueno , Andrade Neto José da Silva , Amorim Júnior Nilson Santana de , Ribeiro Daniel Véras
Published: November 2018

Resumo O reaproveitamento de resíduos industriais para o setor da construção civil tem se mostrado uma alternativa ambiental e economicamente atrativa, principalmente para a indústria do cimento, que por muito tempo tem procurado procedimentos que efetivamente reduzam a alta energia e emissões de CO2 gerados durante a produção de clínquer. Nesse sentido, destaca-se a necessidade de utilização de materiais alternativos na produção de clínquer como substitutos parciais às matérias-primas. Dessa forma, o objetivo da presente pesquisa é avaliar a produção de clínquer Portland com baixa emissão de dióxido de carbono a partir da incorporação de minério não reagido (MNR), resíduo gerado durante a produção de dióxido de titânio (TiO2). As emissões de dióxido de carbono geradas durante a produção desse material foram verificadas através de análises térmicas (TG/DTG), e a influência do resíduo na formação de fases dos clínqueres foi verificada por análise mineralógica (DRX), por microscopia óptica (MO) e por microscopia eletrônica de varredura (MEV). A partir dos resultados obtidos, determinou-se o teor de incorporação ideal de TiO2 para produção de clínquer, sendo constatado que o MNR, até um teor limite de incorporação, atua como mineralizante, sendo, assim, benéfico para a formação de alita.

Resumo O uso da termografia infravermelha tem se tornado alvo de estudos em várias áreas dentro da construção civil. Contudo, as pesquisas de detecção de presença de umidade em edificações ainda estão em desenvolvimento. O objetivo principal deste artigofoi estudar a viabilidadedo uso da termografia para a detecção de infiltrações devido a causas fortuitas em paredes internas. A metodologia consistiu na confecção de paredes de alvenaria de tijolos cerâmicos com diversas configurações de revestimento: sem revestimento, com gesso, gesso com tinta base látex, gessocom tinta base acrílica e gesso com cerâmica assentada com gesso cola. Em cada protótipo foi inserida uma tubulação furada a fim de simular vazamento. O avanço da infiltração foi verificado por meio de termogramas, por um período de 2 h com vazão constante, com 48 h e uma semana após o início da simulação. Os resultados encontrados confirmam que a termografia pode ser eficaz na detecção da região que contém o foco da infiltração oculta, desde que o revestimento não seja impermeável. Esse fato pode ser observado por meio dos gradientes térmicos produzidos. Nos revestimentos porosos ∆T variou entre 2,6 ºC e 3,8ºC, e aqueles com características impermeáveis apresentaram ∆T máximo de 2,2ºC, indicando a influência direta do tipo de revestimentono tempo de surgimento da mancha de umidade de forma aparente.
The orientation and mobility of visual impaired people in bus and subway networks in Brazil
Authors: Silveira Carolina Stolf , Dischinger Marta
Published: November 2018

Abstract Spatial orientation depends both on the information available in the surrounding’s environment and on the individual's ability to perceive and deal with this information. To be fully understand by its users as a transport network and, to independently move from one place to another, the urban public transport service must be able to provide accessible information where users can easily discover and reach different, and to socially engage in local activities. In Brazil, the information disposable to users is scarce and sometimes nonexistent in the urban public transport (PT), especially regarding the supply of information to everyone. This paper presents some doctoral research’s results applied in Brazil and discuss blind users’ orientation and mobility in urban public transport network. The investigation involved around two hundred blind and partially impaired users from many Brazilian regions where surveys were conducted; additionally, interviews with a focus group and the "Accompanied Walks” method. The results of the latter are here presented, showing environmental barriers and users needs.

Abstract Arthropod-borne pathogens are medically important because of their ability to cause diseases in their hosts. The purpose of this study was to detect the occurrence of Ehrlichia spp., piroplasmids and Hepatozoon spp. in dogs with anemia and thrombocytopenia in southern Brazil. EDTA-whole blood was collected from 75 domestic dogs presenting anemia or/and thrombocytopenia from Guarapuava, state of Paraná, Brazil. DNA samples were subjected to conventional PCR assays for Ehrlichia spp. (dsb), piroplasmids (18S rRNA) and Hepatozoon spp. (18S rRNA), followed by sequencing and phylogenetic analyses. Among the 75 dogs, one (1.33%) was positive for Hepatozoon sp. and six (8%) were positive for piroplasmids in 18S rRNA cPCR assays. None of the dogs showed positive results in Ehrlichia spp.-cPCR targeting dsb gene. The phylogenetic analyses revealed that three piroplasm sequences were clustered with Rangellia vitalii, while one sequence was grouped with B. vogeli. The only sequence obtained from Hepatozoon spp.-PCR protocol was pooled with H. canis. Therefore, there is urgent need for differential molecular diagnosis of the two piroplasm species cited as etiological agents in clinical cases of canine hemoparasitic diseases, given the higher pathogenic potential of R. vitalii than of B. vogeli.
Opportunities and challenges for fish culture in Brazilian reservoirs: a review
Authors: Zaniboni-Filho Evoy , Pedron Janaína dos Santos , Ribolli Josiane
Published: November 2018

Abstract Aim Aquaculture plays an important role in the world and in Brazil. Artificial construction of water bodies, such as ponds and reservoirs, has allowed for fish culture in cages in those environments, generating conflicts over the use of these public waters. The producers are seeking to increase production, and the ecosystem is susceptible to the impacts caused by production activity. The aim of this review was to identify questions about these conflicts (productivity × environment) and to indicate possible solutions to the main problems related to fish farming in reservoirs. Methods A bibliographical survey was carried out on the main aspects of cage fish farming in Brazilian reservoirs. Studies from 1977 to 2018 (scientific journals, books, and thesis) were revised using seven databases, the CAPES periodicals portal and Google Scholar websites. The main keywords used were “aquaculture”, “reservoir”, “cage”, “eutrophication”, “carrying capacity”, “impacts”, “oligotrophic”, “escapes”, “hybrids”, and “pollution”. Results We accessed approximately 330 and cited 151 documents. Conclusions The negative aspects associated with cage fish farming, as escapes of cultivated fish, and the possible solutions of this and others negative impacts were addressed, identifying mechanisms for reducing conflicts between environmental impacts and aquaculture production. Potential solutions include the use of native fish species or sterile species, implementation of monitoring systems of the surrounding area, adoption of measures to reduce the accidental escape of fish, use of multitrophic culture systems, use of highly digestible diets with appropriate food management, and use of computer programs that incorporate current and historical environmental data to calculate carrying capacity and choose the most appropriate location for production.

Published: November 2018

Abstract Aim: The aim of this study was to assess the taxonomic aspects and geographical distribution of the periphytic desmids from two different substrates in the littoral zone of an urban artificial lake. Methods Samples of epiphytic and epilithic desmids were collected by grass and rock scraping, respectively, in two stations in the Cascavel municipal lake, Paraná, during April 2015, and March 2016 and 2017. In the laboratory, the taxa obtained from the samples were photographed and their morphometric characteristics recorded. The species composition of the desmid was characterized, and the frequency of occurrence as well as the geographic distribution of each taxon in the Paraná State were recorded. Results We identified 35 taxa, distributed in 10 genera. The most representative were Closterium Nitzsch ex Ralfs and Cosmarium Corda ex Ralfs. A high occurrence of sporadic taxa (60%) was observed and among the recorded taxa, the most frequent were Cosmarium pseudoconnatum Nordstedt var. pseudoconnatum and Desmidium grevillei (Kützing ex Ralfs) De Bary. Nine taxa were exclusive to the epilithic substrate and only Netrium digitus (Ralfs) Itzigsohn & Rothe var. digitus was exclusive to the epiphytic substrate, while the remaining 25 taxa occurred in both substrates. Seven taxa are new records for the Paraná State. Conclusion Although our results are of qualitative nature, they provide baseline data on the biogeographic distribution of taxa, which are crucial for future taxonomic and ecological studies that might contribute to the preservation of the biodiversity.

Authors: Santos Thiago Rodrigues dos , Ferragut Carla , Bicudo Carlos Eduardo de Mattos
Published: November 2018

Abstract Aim Present study evaluated the life forms and taxonomic structure of the periphytic algae community on Utricularia foliosa L. (modified leaf and stem) and artificial substrate during the four seasons in a tropical shallow reservoir. Methods We evaluated the periphyton on natural and artificial substrate in order to evaluate the influence of substrate type on the taxonomic structure of algal community. Monospecific stands of U. foliosa were selected. Water and periphyton sampling were performed within U. foliosa stands in the autumn (April/2010), winter (July/2010), spring (November/2010) and summer (February/2011). Nylon thread was used as the artificial substrate. The community structure was evaluated through life forms, species richness, diversity and species composition. Results Species diversity was significantly different only among seasons. The life forms and species richness were different between substrate types and seasons. Entangled filamentous algae had higher biovolume in the periphyton on artificial substrate and unicellular flagellated algae had higher biovolume on natural substrate. Species composition changed among the seasons and species descriptors differed among substrates types. Species-level taxonomic classification responded clearly to the substrate type. Conclusions We concluded that the taxonomic structure and life forms of periphytic algae on artificial substrate poorly represented the natural periphyton on U. foliosa. The type of substrate strongly influenced the periphyton–Utricularia relationship.

Published: November 2018

Abstract Aim Our objectives were to recognize species that can serve as biological descriptors and evaluate the changes in the phytoplankton community throughout the grow-out period of the Nile tilapia (Oreochromis niloticus Linnaeus 1758) related to management practices and to limnological variables. Methods Samples from the inflow water and the fishpond were collected for the analysis of limnological variables and the structure of the phytoplankton community. Results In the fishpond, we registered a 1.5 times increase in nitrogen and total suspended solids and a 2 times increase in phosphorous compared to the inflow water. During the grow-out period (113 days), 134 taxa belonging to 10 taxonomic classes were registered. Chlorophyceae (60 taxa) and Cyanobacteria (26 taxa) showed the greatest diversity and abundance of species. The largest biovolumes were recorded in the fishpond. Nanoplanktonic species were the most abundant and represented 35% of the descriptor species in the phytoplankton community of the fishpond. Conclusions The instability of the system associated with the control of the hydraulic retention time as a consequence of management practices, favored the presence of species with small cellular dimensions. The decrease in air and water temperature registered at the end of the grow-out period probably favored the increase and persistence of diatoms. Graphical abstract Spatial variation of the main phytoplanktonic taxa in the fishpond.

Authors: Kelkar Prasad A. , Hirekerur Jyoti V.
Published: November 2018

Background: From last few years, the fungal infection has been increasing due to greatly enhanced international traffic and as opportunistic infections in consequence of use of powerful cytotoxic drugs. The disease invariably occurs in diabetics, usually with ketoacidosis, immune compromised patients. Hence, we planned to undertake the present study to evaluate a standard method of management of fungal infections of nose and paranasal sinuses.

Methods: A detailed examination of the nose and pranasal sinuses was carried out in the department of ENT. The patients were continuously monitored with pulse oximetry and ECG monitor. In all patients, nasal endoscopy was performed.  

Results: In this study, fungal infections of the nose and paranasal sinuses were found to be common between 20 and 50 years of age. Aspergillosis was the commonest sinonasal fungal infection followed by allergic fungal sinusitis, rhinosporidiosis and mucormycosis.

Conclusions: Early detection, proper and adequate dose of antifungal agents, timely surgical intervention in the form of debridement and sphenoethmoidectomy and orbital exenteration improve the survival rate in the disease of sinonasal fungal infections.

Authors: Jain Ravi Kant , Jain Abhishek , Mahajan Pranav
Published: November 2018

Background: The objective of this study is to evaluate the tibiofemoral joint space width in the medial and lateral compartments of the knee using digital radiograph. The measurement of knee joint space width (JSW), in between the femur and the tibia is a way of evaluating the tibio-femoral cartilage thickness. This study is aimed at establishing normal references of joint space width for use in diagnosis and follows up of knee cartilage diseases.

Methods: This study is prospective and carried on 50 subjects at SAMC & PGI, Indore, M.P. One patient refused to sign the consent and was excluded. All subjects were healthy adults with sedentary lifestyle. All subjects underwent x-ray of bilateral knee joints. The joint space width of both medial and lateral compartments of each knee was measured using the scale in the computerized software.

Results: The average age in the study group was 44.59 years with male preponderance.The mean left medial and lateral joint space width was 5.34 mm±1.26 mm and 5.21 mm±1.04 mm and on right side was 5.26±1.11 mm and 5.57±1.57 mm, respectively. No statistically significant difference was found between right and left knee joint space width compartments.

Conclusions: The values obtained after observing the radiographic references showed no significant gender variation in knee joint space width. But, it is seen that there is a decrease in joint space width with increasing age, which progresses towards osteoarthritis of knee.

Published: November 2018

The mineral components of the foodstuff consumed by an individual are important in the growth and development of a human being. In recent years red fruits, because of their potential beneficial health effects, are getting attention of both consumers and manufacturers. One of the red fruits, Cornelian cherry (Cornus mas L.), was investigated in terms of both mineral components and antioxidant properties. The mineral components include calcium (Ca), iron (Fe), potassium (K), magnesium (Mg), and zinc (Zn) in this fruit were determined using flame atomic absorption spectrometry (FAAS). The antioxidant activity tests were applied to the extracts obtained using different solvents to examine the antioxidant properties of this fruit. Statistical analysis indicated that while the best results were obtained from acetone extracts, the lowest results were obtained from water extracts for all antioxidant activity tests (p<0.05). The best average values for DPPH and ABTS radical scavenging capacity, reducing power, total phenolic content and total flavonoid content in acetone extracts were found to be 1053.72±38.12 mg TEAC/100 g FW and 2907.34±152.05 mg TEAC/100 g FW, 5894.99±251.05 mg TEAC/100 g FW, 2979.25±69.40 mg GAE/100 g FW and 255.75±14.92 mg QE/100 g FW, respectively.

Published: November 2018

Rivaroxaban
is a direct factor Xa inhibitor and has been safely used since 2008. It is used
for the detection of atrial fibrillation and venous thromboembolism.
Pancreatitis is one of the rare but dangerous side effects of rivaroxaban. The
case of a 53-year-old female patient that developed in the third month of drug
usage was evaluated, and it was confirmed after a full analysis was conducted
that excluded all other factors, such as biliary calculus, alcohol usage, hypertriglyceridemia,
biochemical parameters, ultrasonography and computed tomography that the
patient’s condition was caused by the use of Rivaroxaban. The aim of this case presentation
is to indicate that awareness should be increased regarding the risks of using
the drug Rivaroxaban, as it could lead to drug-induced pancreatitis, even
though this is rare.

Purpose: This study provides an overview of the self-defined skills and practices of European orthopedic nurses in empowering patient education. Nurses themselves have highlighted the necessity to enhance their own skills, but possibilities for further education have been limited. Methods: The data (n = 317 nurses) from a structured survey were collected during the years 2009–2012 in seven European countries with an EPNURSE—questionnaire (Empowering Patient Education from the point of view of Nurses). Results: Nurses considered patient education as an important part of their work and evaluated their own skills as good. However, their patient education practices were based more on practices on their ward and their own experience than on further education or evidence-based knowledge. On the other hand, lack of time for patient education and experienced overload were the major barriers experienced by nurses. Implications for Practice: Further education of orthopedic nurses in empowering evidence-based patient education is highly needed. Nurse leaders need to acknowledge the strong need for supporting nurses within clinical practice, improve their evidence-based knowledge and support practices that prioritize patient education within the hospital environment. Further international collaboration in nursing research and health-care organizations is desirable to reach these patient educational goals in clinical nursing practice.
The Effects of a Health Partner Program on Alleviating Depressive Symptoms Among Healthy Overweight/Obese Individuals
Authors: Liu Tingting
Published: November 2018

Background and Purpose:Although lifestyle interventions have been shown to be effective in losing weight and increasing physical activity in community settings, little is known whether these programs may also ameliorate negative mood states in healthy overweight/obese adults when such programs are delivered in workplace settings. The aim of the study was to determine whether a health partner program may alleviate depressive symptoms among healthy overweight/obese individuals at 1 year.Methods:A secondary data analysis was performed using the Center for Health Discovery and Well Being database at Emory University in the United States. A total of 297 healthy overweight/obese university employees were recruited from the health partner program. Participants worked with health partners to establish an individualized health action plan, which might include changes in diet or exercise, modification of risk-related behaviors (e.g., tobacco use, alcohol use), and stress reduction strategies such as yoga. Depressive symptoms were measured by the Beck Depression Inventory-II at baseline and one-year follow-up.Results:At baseline, 9.7% of participants had depressive symptoms. At one-year follow-up, these participants had a small-to-moderate improvement in depressive symptoms (Cohen’s d = 0.423), and the changes in depressive symptoms were statistically significant (p< 0.001).Implications for Practice:Since overweight/obese individuals are more likely to experience depressive symptoms than normal-weight individuals, early interventions to steer these individuals to better mental health are therefore essential. This study has demonstrated the potential benefits of a health partner program on alleviating depressive symptoms among overweight/obese individuals and this should be integrated into clinical practice.
Thermodynamic Analysis of a Modified Autonomous Flow Control Device for SAGD Sub-Cool Management
Authors: Konopczynski Michael
Published: November 2018

This paper describes the application of Autonomous Inflow Control Devices to manage sub-cool in SAGD bitumen production wells. A modification of the AICD is proposed to increase the effectiveness of its performance restricting premature steam breakthrough.

Typical nozzle, short tube, and hybrid type passive ICD's are good at creating uniform inflow by creating additional pressure drop and flow restriction along the length of the wellbore, but once the steam/water interface reaches the device, the steam preferentially flow through at a higher rate with less pressure drop, creating further pressure drop in the steam chamber surrounding the device, more steam flashing, and a runaway situation which can only be cured by increasing the back pressure on the whole well.

The Autonomous Inflow Control Device (AICD) is an active flow control device that delivers a variable flow restriction in response to the properties of the fluid flowing through it. The RCP type of autonomous inflow control device (AICD) is much more effective in restricting vapour phased flow compared to liquid phased flow. The flow resistance of the RCP AICD is dictated by the viscosity and density of the fluid entering the device, not by what exits. As such, it does not create maximum flow resistance until steam reaches it, and for the SAGD process, this is too low a sub-cool value. By adding a small pressure drop upstream of the AICD, the device can respond to the onset of steam flashing, creating a significant pressure restriction and maintaining the desired sub-cool.

To ensure the proper design of the device and demonstrate its effectiveness in controlling steam flashing, the flow performance must be modelled honouring the thermodynamics of the associated phase changes.

The performance of the modified AICD is analysed in its ability to produce bitumen and water with minimum pressure drop while providing maximum control of wellbore steam flashing. Thermodynamic modelling demonstrates the ability of the modified AICD to reduce the impact of downstream pressure on the maintenance of desired sub-cool, allowing all zones in the SAGD wellbore to be produced at optimum drawdown and maximum rates. The study examines the performance of the device at a variety of flow rates, fluid types, and water conditions upstream of the device, from 10 C sub-cool to 10% steam quality, and compares it to the performance of traditional flow control devices.

The modified AICD provides a new and effective approach to managing SAGD sub-cool and maximizing bitumen productivity from a SAGD well, and ultimately improving steam chamber conformance and SAGD economics.

Geochemical modeling was used to design and conduct a series of alkaline/surfactant/polymer (ASP) coreflood experiments to measure the surfactant retention in limestone cores using sodium hydroxide (NaOH) as the alkali. Surfactant/polymer (SP) coreflood experiments were conducted under the same conditions for comparison. NaOH has been used for ASP floods of sandstones, but these are the first experiments to test it for ASP floods of limestones. Two studies performed under different reservoir conditions showed that NaOH significantly reduced the surfactant retention in Indiana Limestone. An ASP solution with 0.3 wt% NaOH has a pH of approximately 12.6 at 25°C. The high pH increases the negative surface charge of the carbonate, which favors lower adsorption of anionic surfactants. Another advantage of NaOH is that low concentrations of only approximately 0.3 wt% can be used because of its low molecular weight and its low consumption in limestones. Most reservoir carbonates contain gypsum or anhydrite, and therefore sodium carbonate (Na2CO3) will be consumed by the precipitation of calcium carbonate (CaCO3). As shown in the two studies, NaOH can be used in limestone reservoirs containing gypsum or anhydrite.
An Enriched Approach for Modeling Multiscale Discrete-Fracture/Matrix Interaction for Unconventional-Reservoir Simulations
Authors: Xia Yang , Jin Yan , Chen Mian , Chen Kang Ping
Published: November 2018

Unconventional reservoirs after formation-stimulation treatments are always characterized by complex fracture networks with a wide range of length scales and topologies. Accurate simulation on multiscale discrete-fracture/matrix interaction during transient productive flows for such reservoirs is challenging but important for reservoir evaluation, optimization, and management.

In this paper, we present a new enriched and explicit method for simulation on multiscale discrete-fracture/matrix modeling (EE-DFM) on structured grids to decouple the mesh conformity between the porous media and the fractures. A hybrid structured EE-DFM is first introduced, and enrichments for different scales of fracture segments are proposed to locally enrich the conventional approximation space for representing the pressure solution surrounding multiscale fracture networks. By appropriately selecting an asymptotic function to locally enrich the conventional approximation space, typical behavior of fluid flux around features in fractured media, such as discontinuities and singularities, can be directly captured. Simulation on complex multiscale fracture networks is achieved by using the superposition principle of the enrichments without introducing additional degrees of freedom and while maintaining computational efficiency. We demonstrate the accuracy and flexibility of the method by performing a series of case studies and comparing the results with simple analytical solutions as well as with conventional numerical solutions. The results of long-term well-performance case studies are used to show the good computational efficiency of the proposed method when the complexity of fracture networks is increased. The potential of the proposed method to be incorporated into the multicontinuum concept for solving nonlinear gas transport in a shale reservoir is presented. The present study provides a promising framework for real-field multiscale discrete-fracture models for unconventional-reservoir simulations.
