Managing and determination of the blood lipid profile and oxidative status are useful tool to show the influence of foreign chemical substances on production of dairy cows. Investigation of various biomarkers of oxidative stress related to various problems in the production dairy cows presents a very important issue. The aim of this research was to investigate different biological markers in two different breeds of dairy cows – the Holstein Friesian and the Simmental, during different stages of lactation. The total of 60 Holstein Friesian and Simmental cows were divided into two treatments (HF and S) which was further divided into three groups each, respectively. Lactating groups of each cow breed was divided into three stages at early lactation of 32-75 days (HF1 and S1), peak lactation of 80-165 days (HF2 and S2) and low lactation of 175 days onward (HF3 and S3). During the research the total milk production and the percentage of
milk fat and protein were determined. Blood samples were collected from
jugular vein of each cow, the serum was harvested without anticoagulant
and stored at -20 °C in small aliquots till further analysis. Serum was
then analyzed for triglyceride, cholesterol, HDL, LDL, AST, ALT, GGT, the total antioxidant status (TAS), the total oxidant status (TOS), MDA,
SOD, catalase and paraoxonase (PON1). Significantly (P<0.05) higher values of cholesterol, TOS and SOD at peak lactation stage was observed in all cows. A gradual decline from early lactation to low lactation was
observed in the values of triglycerides and ALT, while MDA gradually increased from the same stage in all cows. The values of LDL and catalase showed an irregular pattern of variations in various lactation stages among all groups. The Holstein Friesian breed showed significantly higher values of ALT and PON1, while values of HDL, TAS and TOS were the lowest in Simmental group (P<0.05). By measuring the
signs of oxidative stress, it was concluded that metabolic efforts of cows during the peak of lactation affected the investigated parameters. Disturbance in feed intake and rise in metabolic processes lift up oxidative stress in cows, especially during the peak of lactation, which
might be determined by monitoring blood alterations. Results of our study indicated that the Holstein Friesian breed was under higher oxidative stress during different lactation stages compared to Simmental
dairy cows.
Kinematic and dynamic analysis of a serial manipulator with local closed loop mechanisms
Authors: My Chu Anh , Hoan Vu Minh
Published: April 2019

This paper addresses the kinematic and dynamic modelling and analysis for a robot arm consisting of two hydraulic cylinders driving two revolute joints of the arm. The two cylinders and relevant links of the robot constitute two local closed kinematic chains added to the main robot mechanism. Therefore, the number of the generalized coordinates of the mechanical system is increased, and the mathematical modelling is more complex that requires a formulation of constraint equations with respect to the local closed chains. By using the Lagrangian formulation with Lagrangian Multipliers, the dynamic equations are first derived with respect to all extended generalized coordinates. Then a compact form of the dynamic equations is yielded by canceling the Multipliers. Since the obtained dynamic equations are expressed in terms of independent generalized coordinates which are selected according to active joint variables of the arm, the equations could be best suitable for control law design and implementation. The simulation of the forward and inverse kinematics and dynamics of the arm demonstrates the motion behavior of the robot system.

Published: April 2019

The purpose of this article is to develop a mathematical model for estimating the value of a real estate object, taking into account the trends in the residential real estate market using indicators of the object’s state and indicators of the real estate market. The real estate market is a complex mechanism that includes subjects, objects, processes and infrastructure. The real estate market has its own characteristics that distinguish it from the market of goods and services related to the duality of real estate, its special characteristics. Despite the high conservatism, there are certain innovative trends in the development of the residential real estate market (innovations in construction, architecture, services and marketing, logistics, customer focus).
The article considers the residential real estate market as a complex socio-technical system, to predict the development of which it is advisable to use a combination of classical forecasting methods and soft computing or intelligent data processing methods. A forecast of the development of the residential real estate services market was made using foresight technologies (industry roadmap). The analysis was carried out and the main factors acting on the market were identified, and their influence on the development of market trends was determined. A mathematical model for predicting the value of residential real estate based on the theory of fuzzy sets has been developed.

Background

Worst-case, typical, and best-case scenarios for survival, based on simple multiples of an individual's expected survival time (EST), estimated by their oncologist, are a useful way of formulating and explaining prognosis. We aimed to determine the accuracy and prognostic significance of oncologists’ estimates of EST, and the accuracy of the resulting scenarios for survival time, in advanced gastric cancer.

Materials and Methods

Sixty-six oncologists estimated the EST at baseline for each of the 152 participants they enrolled in the INTEGRATE trial. We hypothesized that oncologists’ estimates of EST would be unbiased (∼50% would be longer or shorter than the observed survival time [OST]); imprecise (<33% within 0.67–1.33 times the OST); independently predictive of overall survival (OS); and accurate at deriving scenarios for survival time with approximately 10% of patients dying within a quarter of their EST (worst-case scenario), 50% living within half to double their EST (typical scenario), and 10% living three or more times their EST (best-case scenario).

Results

Oncologists’ estimates of EST were unbiased (45% were shorter than the OST, 55% were longer); imprecise (29% were within 0.67–1.33 times observed); moderately discriminative (Harrell's C-statistic 0.62, p = .001); and an independently significant predictor of OS (hazard ratio, 0.89; 95% confidence interval, 0.83–0.95; p = .001) in a Cox model including performance status, number of metastatic sites, neutrophil-to-lymphocyte ratio ≥3, treatment group, age, and health-related quality of life (EORTC-QLQC30 physical function score). Scenarios for survival time derived from oncologists’ estimates were remarkably accurate: 9% of patients died within a quarter of their EST, 57% lived within half to double their EST, and 12% lived three times their EST or longer.

Conclusion

Oncologists’ estimates of EST were unbiased, imprecise, moderately discriminative, and independently significant predictors of OS. Simple multiples of the EST accurately estimated worst-case, typical, and best-case scenarios for survival time in advanced gastric cancer.

Implications for Practice

Results of this study demonstrate that oncologists’ estimates of expected survival time for their patients with advanced gastric cancer were unbiased, imprecise, moderately discriminative, and independently significant predictors of overall survival. Simple multiples of the expected survival time accurately estimated worst-case, typical, and best-case scenarios for survival time in advanced gastric cancer.

Published: April 2019

Background

The impact of cisplatin use on long-term survival of unselected patients with advanced urinary tract cancer (aUTC) has not been adequately investigated. We used a multinational database to study long-term survival and the impact of treatment type in unselected patients with aUTC.

Materials and Methods

A total of 1,333 patients with aUTC (cT4bN0M0, cTanyN+M0, cTanyNanyM+), transitional-cell, squamous, or adenocarcinoma histology who received systemic chemotherapy and had available survival data were selected. Long-term survival was defined as alive at 3 years following initiation of first-line chemotherapy. Conditional overall survival (COS) analysis was employed to study change in prognosis given time survived from initiation of first-line chemotherapy.

Results

Median follow-up was 31.7 months. The combination of cisplatin use and cisplatin eligibility accurately predicted long-term survival. Eligible patients treated with cisplatin conferred a 31.6% probability of 3-year survival (95% confidence interval [CI]: 25.1–38.3), and 2-year COS for patients surviving 3 years after initiation of cisplatin-based chemotherapy was 83% (95% CI: 59.7–93.5). The respective probabilities for patients who were ineligible for cisplatin or not treated with cisplatin despite eligibility were 14% (95% CI: 10.8–17.6) and 49.3% (95% CI: 28.2–67.4). Two-year COS remained significantly different between these two groups up to 3 years after chemotherapy initiation.

Conclusion

Cisplatin-based therapy was associated with the highest likelihood of long-term survival in patients with aUTC and should be used in patients who fulfill the established eligibility criteria. Novel therapies are necessary to increase long-term survival in cisplatin-ineligible patients.

Implications for Practice

Long-term, disease-free survival is possible in one in four eligible-for-cisplatin patients with advanced urinary tract cancer (aUTC) treated with cisplatin-based combination chemotherapy. Therefore, deviations from eligibility criteria should be avoided. Consolidation surgery should be considered in responders. These data provide benchmarks for the study of novel therapies in aUTC.

Published: April 2019

Justificativa e Objetivos: A morte de mulheres em idade reprodutiva é um evento de grande magnitude em todo o mundo, mas o perfil é distinto entre as regiões de alta e baixa renda. O presente estudo teve como objetivo analisar causas básicas e fatores associados aos óbitos de mulheres em idade reprodutiva no Piauí, de 2008 a 2012. Métodos: Estudo descritivo de base populacional, com dados de todas as declarações de óbitos de mulheres entre 10 a 49 anos registradas no Comitê de Mortalidade Materna do Piauí. Foram calculados odds ratio (OR) e intervalos de confiança de 95% (IC95%) para avaliar a associação entre as variáveis. Resultados: Neoplasias (20,9%), doenças cardiovasculares (18,8%), causas externas (18,6%) e maternas (5,5%) foram as causas básicas mais encontradas. Causas externas e maternas predominaram entre 10 a 29 anos e, a partir de 35 anos, neoplasias e doenças cardiovasculares. A mortalidade materna foi mais provável de ocorrer em municípios do interior (OR=2,04; IC95% 1,51-2,33), com até 50.000 habitantes (OR=1,33; IC95% 1,16-1,78) e com IDH-M < 0,566 (OR=1,42; IC95% 1,34-2,01). Conclusões: O padrão de mortalidade é semelhante ao encontrado na população feminina brasileira em idade fértil, sendo que as principais causas básicas encontradas poderiam ser evitadas mediante a implementação de medidas de intervenção.

Published: April 2019

Justificativa e Objetivos: Staphylococcus aureus resistente à meticilina (MRSA) é uma das causas mais frequentes de infecções relacionadas à assistência à saúde e comunitárias, e com seu avanço, a vancomicina tornou-se a principal opção terapêutica. Entretanto, o seu uso indiscriminado favoreceu o surgimento de MRSA com reduzida suscetibilidade à vancomicina, comumente associados com falhas no tratamento, bacteremia persistente, hospitalização prolongada e desfechos clínicos adversos. Este estudo avaliou a ocorrência de MRSA com reduzida suscetibilidade à vancomicina e determinou algumas características moleculares em comparação com MRSA suscetível à vancomicina (VS-MRSA). Métodos: Determinação do perfil de suscetibilidade aos antimicrobianos, a concentração inibitória mínima (CIM) e concentração bactericida mínima (CBM) para vancomicina, tolerância à vancomicina, tipagem do SCCmec e agr foram realizadas em um total de 177 MRSA. Posteriormente, foram triados para hVISA por BHIA-3V e BHIA-6V e confirmados com a Análise do Perfil Populacional - Área Abaixo da Curva (PAP-AUC). Resultados: Os fenótipos VT-MRSA e hVISA foram encontrados em 13,6% e 5,1% dos isolados clínicos de MRSA, respectivamente, e a presença de hVISA foi estatisticamente significativa entre os isolados de VT-MRSA (p

Published: April 2019

Justificativa e objetivos: Hepatite B é infecção viral universalmente prevalente e considerada a doença ocupacional infecciosa mais importante entre os profissionais de saúde, e o trabalhador de Enfermagem, por desenvolver ações invasivas em quantidade e frequência intensas, constitui grupo de extrema vulnerabilidade. Imunidade obtida por vacinação constitui estratégia preventiva eficaz, entretanto, cerca de 10% dos vacinados não alcançam títulos protetores de anticorpos, sendo necessário teste sorológico para confirmar imunidade. O objetivo deste estudo foi investigar o conhecimento da equipe de enfermagem sobre situação vacinal e perfil de imunoproteção para hepatite B. Métodos: Estudo epidemiológico, analítico, com 70 trabalhadores de um hospital público de referência regional no Estado da Paraíba. Após consentimento, foram submetidos à entrevista, coleta de sangue e testes sorológicos para detecção dos marcadores HBsAg e anti-HBs,em duplicata, por Eletroquimioluminescência. Os dados coletados foram processados no SPSS versão 22.0 e analisados por estatística descritiva. Resultados: A maioria dos participantes é do sexo feminino (85,7%), com média de idade de 33,4 anos e nível médio de escolaridade (75,7%). Sobre a situação vacinal, 65,7% declararam possuírem esquema completo e 12,9% não lembravam/não sabiam se já haviam recebido imunobiológico.Sobre o teste para verificação do status imunológico, 25,7% informaram desconhecerem a existência de teste específico para tal detecção. Houve associação significativa entre categoria profissional e conhecimento sobre o Anti-HBs. Conclusão: O desconhecimento dos trabalhadores de enfermagem sobre seu status vacinal e imunológico os colocam em vulnerabilidade constante para a hepatite B, sinalizando a urgência de atitudes institucionais protetivas para este público.
Dinâmica familiar e esquemas formados em adolescente vítima de violência sexual: um estudo de caso
Authors: Boaventura Lima Amanda
Published: April 2019

A violência sexual é caracterizada por uma relação heterossexual ou homossexual, que parte de um agente em estágio de desenvolvimento mais adiantado e/ou de mais poder e tem por finalidade a estimulação sexual ou a utilização do outro para obtenção de prazer sexual. Os esquemas se desenvolvem como resultado de experiências nocivas de infância, por exemplo, situações de abuso.  Considerando a terapia focada em esquemas e a literatura sobre violência sexual em crianças e adolescentes, objetivou-se avaliar uma adolescente de 14 anos vítima de violência sexual durante a infância nos seguintes aspectos: 1. identificar os esquemas iniciais socialmente desadaptados decorrente do abuso sexual. 2. Identificar os esquemas mal adaptativos provenientes da dinâmica familiar; 3. Verificar os comportamentos e as formas de enfrentamento atuais estabelecendo uma relação com a violação de direitos e sua estrutura familiar. Realizou-se uma entrevista semiestruturada e foram aplicados o Questionário de Esquemas de Young e Questionário de estilos parentais. Constataram-se na participante os esquemas de abandono/instabilidade, desconfiança/abuso e dependência/ incompetência com predomínio de estratégias de enfrentamento resignação e “hipercompensação”. Como consequência observou-se retração das relações sociais e distanciamento afetivo da mãe. Os resultados auxiliam na compreensão de sua dinâmica familiar, do ajustamento psicológico e investigação da prevalência dos EIDs em crianças abusadas sexualmente e das consequências para a vítima.
Da institucionalização total à medicalização: relatos sobre os dispositivos de saúde mental em Feira de Santana – BA
Authors: Macêdo Stefanie de Almeida , Barboza Willima Cintia Santos , Tsukuda Yonetane Freitas
Published: April 2019

Este artigo tem por objetivo construir um breve histórico do cuidado em saúde mental, dos primórdios da institucionalização total aos processos de medicalização contemporâneos, tendo como pano de fundo as experiências de estágio de Psicologia vivenciadas no Hospital Especializado Lopes Rodrigues (HELR) e demais dispositivos de saúde mental da cidade de Feira de Santana, Bahia. As reflexões tecidas por Michel Foucault, Franco Basaglia, Erving Goffman e Paulo Amarante, contrapostas e comparadas à vivência do estágio, apontaram para a transição do processo de institucionalização total para o de medicalização da vida. Por meio desta investigação foi possível constatar a permanência de discursos e práticas que não se coadunam com a legislação vigente, a qual propõe um complexo processo de desinstitucionalização em saúde mental, bem como contatar o papel do psicólogo na manutenção deste estado de coisas.
A influência do padrão de magreza para a mulher na contemporaneidade
Authors: Hessel Beatriz Ribeiro Cortez Cardozo Barata de Almeida , Furtado Izaura Maria Carvalho da Graça
Published: April 2019

A presente investigação apresenta como tema central o padrão de magreza para a mulher na sociedade brasileira, sendo este o modelo de beleza hegemônico a ser seguido na contemporaneidade. Tem como objetivo compreender os fatores socioculturais contemporêneos que contribuem para que o padrão de magreza torne-se um instrumento de disciplinarização subjetiva sobre os corpos femininos. A metodologia empregada foi a revisão de literatura narrativa, de cunho qualitativo, com análise de contéudo temática. Os resultados encontraram a maneira como o gênero feminino é construído e como este participa do processo sociocultural de submissão ao ideal de beleza pesquisado. Também foi encontrado que à mulher é reservado um lugar de inferioridade em relação ao homem e foi questionado o conceito de saúde relacionado ao corpo gordo. Além disso, foi investigado como as práticas discursivas são mantenedoras do lugar social atribuído ao feminino e o papel da mídia hegemônica na construção e naturalização do padrão de magreza, ao utilizar o habitus e as representações sociais para esta finalidade. Deste modo, concluiu-se que a mídia hegemônica contribui para a reafirmação do lugar de submissão da mulher e da imposição do padrão de magreza à ela, por meio do agenciamento dos desejos femininos. A alimentação, neste contexto, torna-se restritiva para que a mulher alcance este ideal de beleza e se purifique de seus pecados. Com este estudo, espera-se contribuir com os estudos de gênero, ampliando ainda mais esta área de pesquisa.
Entre trilhos e trilhas: relato de experiência da utilização da Aprendizagem Baseada em Problemas em um curso de psicologia
Authors: Sampaio Carla Oliveira , Queiroz Anabela
Published: April 2019

A Aprendizagem Baseada em Problemas (ABP) é um método de ensino-aprendizagem que tem como base a construção ativa do conhecimento por parte do estudante. Implantado em um curso de psicologia na cidade de Salvador/Bahia em 2009, tem gerado reflexões por parte do corpo docente acerca da adequação na sua utilização, consideradas as especificidades dessa área do conhecimento, as adaptações estruturais necessárias ao contexto em que é aplicado e à formação de seu grupo de tutores. Objetiva-se contrapor as regras estabelecidas para sua utilização aos caminhos percorridos ao longo de sete anos de história com o método no referido curso, a partir do relato de experiência de uma das tutoras, decorrente de reflexões acerca da sua prática pedagógica com o método e da sua participação em reuniões institucionais. Conclui-se que a estrutura do método é importante para que se tenha um direcionamento pedagógico, e que adaptações são necessárias ao contexto em que é aplicado. Porém, seu principal objetivo não deve ser desvirtuado, ou seja, o deslocamento subjetivo do estudante para o lugar de construtor do conhecimento.

MEDIA COVERAGE BEYOND VISIBILITY: THE CASE OF THE PORTUGUESE ANTI-AUSTERITY PROTESTS
Authors: Valentim Vicente , Baumgarten Britta
Published: April 2019

What conditions lead to extensive and positive media coverage of protests? Research shows that violence and size increase media coverage, but past studies have not given much attention to the causes of intense coverage that is highly positive. To fill this gap, we run QCA analyses on 63 actions in the Portuguese wave of anti-austerity protests to consider three outcomes: visibility, resonance, and legitimacy. Our findings show that neither violence nor size are sufficient for any of these outcomes, and that other conditions help explain them. Extensive and supportive media coverage results when these factors are combined with conditions such as protest size, type of organizer, international context, violence, and action form.
EXPLAINING OFFLINE PARTICIPATION IN A SOCIAL MOVEMENT WITH ONLINE DATA: THE CASE OF OBSERVERS FOR FAIR ELECTIONS
Authors: Koltsova Olessia Y. , Selivanova Galina
Published: April 2019

This article investigates to what extent activity of a social movement on a social networking site is related to participation in offline collective action. This research contributes to a broader theory of effective communicative structures of social movements. We use the data from seventeen online groups representing the branches of the Observers for Fair Elections movement in districts of St. Petersburg, Russia, and compare their online properties to offline participation of movement members as electoral observers. We find that while prediction of individual offline participation with this online data is of limited power, association between district participation rates and online group features is very strong. Large, more inclusive and evenly connected networks, where people engage in high-threshold online activities, produce more offline participants; weak individual-level prediction, combined with strong group-level prediction, suggests either the presence of the “network effect” or of third factors—e.g., prior contentious experience or the leaders' effect.

Оценка доходности фондов прямых частных инвестиций в современных зарубежных эконометрических подходах
Authors: Мусатова Мария Михайловна
Published: April 2019

В статье анализируются сложившиеся в последние десятилетия зарубежные подходы к оценке доходности прямых частных инвестиций на основе эконометрического моделирования. Стремительный рост мировой индустрии прямых частных инвестиций (private equity, РЕ) стал сталкиваться с завышенной оценкой будущих доходов, с замедлением доходности растущих фондов прямых частных инвестиций, с необходимостью полностью задействовать конкурентные преимущества этого вида инвестиций и т.д. В статье рассмотрены недостатки использования традиционных показателей финансового менеджмента для оценки доходности РЕ, приведены противоположные точки зрения и их аргументация на взаимосвязь доходности и масштабов роста фондов прямых частных инвестиций, систематизированы преимущества ведения операционного менеджмента в непубличных компаниях менеджерами РЕ, обеспечивающего более высокую доходность по сравнению с франчайзинговыми схемами ведения бизнеса в сфере, ориентированной на массового потребителя услуг. Критический анализ этих подходов, представляется, безусловно, актуальным на фоне намечающегося восстановления индустрии PE в России. Завершение рецессии, стабилизация цен на нефть и адаптация российской экономики к санкционному режиму усиливают интересы инвесторов к российским активам непубличных компаний. Как представляется, на этом позитивном фоне российским РЕ необходимо представлять тенденции доходности на развитых рынках РЕ с историей и огромным опытом работы, выявленных с помощью эконометрического моделирования.

Authors: Макаров Иван Николаевич , Евсин Максим Юрьевич , Кокарев Артем Леонидович , Крупина Тамара Александровна
Published: April 2019

В работе рассматриваются методологические проблемы, связанные с оценкой бизнеса. Авторы исходят из предположения, что в современных условиях бизнес в процессе оценки необходимо рассматривать как систему, включающую два базиса: фирму, как имущественный комплекс и, одновременно, материальную основу бизнеса, и, собственно, сам бизнес, как определенная экономическая деятельность, ведущаяся в определенных технико-социо-экономических условиях. При этом показано, что при оценке бизнеса как деятельности необходимо учитывать отраслевые перспективы данной деятельности, меняющиеся в процессе технологического развития хозяйственных систем.

Тенденции развития электроэнергетического комплекса России в условиях трансформации системных вызовов
Authors: Салыгин Валерий Иванович , Мустафинов Руслан Камильевич
Published: April 2019

Инфраструктурное развитие энергетического комплекса России, сопряженное с аспектами реализации инновационной парадигмы, проходит через процесс преобразования коммерческого базиса. Это обусловливает перманентное совершенствование экономических механизмов и законодательной базы. В работе приведен детальный анализ ретроспективы формирования модели энергетического комплекса. Наряду с этим раскрыта специфика современного устройства торгового взаимодействия и обозначены перспективы трансформации в контексте модернизации основных фондов и проведения цифровизации отраслевых процессов. Совокупность представленного в статье материала позволяет сделать вывод, что фрагментированность текущей концепции отраслевого развития и необходимость оптимизации широкого перечня вопросов взаимодействия в формате государство-коорпорации-потребитель исключает возможность принятия односторонних финансовых решений.
