The Theory-Based View: Economic Actors as Theorists
Authors: Felin Teppo , Zenger Todd R.
Published: December 2017

This paper outlines the theory-based view of strategy and markets. We argue that novel or “great” strategies come from theories. Entrepreneurs and managers originate theories and hypotheses about which activities they should engage in, which assets they might buy, and how they will create value. A firm’s strategy, then, represents a set of contrarian beliefs and a theory—a unique, firm-specific point of view—about what problems to solve, and how to organize and govern the overall process of value creation. We outline the cognitive and perceptual, organizational, and economic foundations of the theory-based view of strategy. We also discuss the essential attributes needed for a firm-level theory of strategy. Throughout the paper we offer informal examples of our argument, by briefly discussing the strategies of companies like Apple, Uber, Disney, Wal-Mart, and Airbnb. The theory-based view of strategy and markets also offers important insights for how firms govern themselves (including ownership, boards, and organization design) and how firms interact with capital markets and external evaluators and stakeholders. We conclude with a discussion of the practical and managerial applications of the theory-based view.
Computational calculation of the relative phase of the MnN compound
Authors: Espitia R. Miguel Jose , Diaz Forero John Hernan , Salcedo Parra Octavio Jose
Published: December 2017

In this work computational calculations ab initio were performed to determine the
relative stability, the structural and electronic properties of manganese nitride MnN.
The calculations were made in the structures NaCl, Zincblenda, CsCl and wurtzita;
using the method increased plane waves and linearized in the full potential version
(FP-LAPW), within the formalism of the density functional theory (DFT). We find
that the most stable crystallization phase is Zincblende and that the compound can
pass to the NaCl structure by applying an external pressure. From the DOS state
density, it is found that the manganese nitride has a metallic behavior due to the
Mn-d and N-p orbitals that cross the Fermi level; MnN possesses magnetic
properties with a magnetic moment of 2.53 ÂµÎ²/cell.
Regulação emocional e comportamento alimentar perturbado: O impacto distinto da fusão cognitiva e de uma atitude de apreço em relação à imagem corporal
Authors: Bento Sofia , Ferreira Cláudia , Mendes Ana Laura , Marta-Simões Joana
Published: December 2017

Diferentes processos de regulação emocional parecem estar envolvidos na relação entre a avaliação negativa da imagem corporal e a psicopatologia alimentar. O presente estudo pretendeu clarificar, numa amostra de 369 mulheres, os efeitos distintos da fusão cognitiva e do apreço pela imagem corporal na relação entre a discrepância sentida entre o corpo real e idealizado e o comportamento alimentar perturbado, quando controlado o efeito do IMC. Os resultados indicaram que mulheres que percecionam o seu corpo como significativamente discrepante do padrão valorizado na sociedade atual têm uma maior tendência para apresentar comportamentos alimentares perturbados. No entanto, esta relação é parcialmente explicada por maiores níveis de fusão cognitiva em relação à aparência física e por um menor apreço pela própria imagem corporal. Estes resultados constituem um contributo significativo ao sublinharem a relevância da promoção de desfusão cognitiva e de atitudes autocompassivas enquanto estratégias de regulação emocional protetoras da psicopatologia alimentar.
Cuidados paliativos oncológicos em contexto de internamento e domiciliário: Necessidades, morbilidade psicológica e luto antecipatório nos familiares do doente terminal e impacto na qualidade de vida familiar
Authors: P. Areia Neide , Major Sofia , Gaspar Catarina , Relvas Ana Paula
Published: December 2017

A doença oncológica na fase terminal tem um importante impacto na família e seus elementos. Por este motivo, os cuidados paliativos pressupõem o suporte à família. No entanto, são escassos os estudos que visam determinar as necessidades das famílias em cuidados paliativos. O presente estudo teve como objetivos determinar quais as necessidades dos familiares dos doentes terminais, a presença de morbilidade psicológica e experiência de luto antecipatório, distinguindo dois contextos de prestação de cuidados (internamento e domicílio), e examinar a influência de uma satisfação inadequada das necessidades, luto antecipatório e contexto de prestação de cuidados na perceção de qualidade de vida familiar. Para tal, procedeu-se a um estudo exploratório junto de uma amostra de 40 familiares de doentes oncológicos terminais em cuidados paliativos. Verificou-se que as necessidades de suporte psicossocial são menos satisfeitas em contexto de cuidados domiciliários. Independentemente do contexto de prestação de cuidados, os familiares apresentam níveis clinicamente significativos de morbilidade psicológica e luto antecipatório com impacto na perceção da qualidade de vida familiar. A satisfação inadequada das necessidades, a presença de morbilidade psicológica e a experiência de luto antecipatório influenciam a perceção de qualidade de vida familiar. Este estudo vem demonstrar a importância de atender às necessidades dos familiares em cuidados paliativos, numa perspetiva holística e multidisciplinar.
Mediastinal teratoma with mature fetal pancreatic tissue, nesidioblastosis and focal hyperplasia of neuroendocrine cells. A case report
Authors: Rumyantsev Pavel O. , Abrosimov Aleksandr Yu. , Tertychnyi Aleksandr S. , Selivanova Liliya S. , Slashchuk Konstantin Yu.
Published: December 2017

We present a clinical case of rare and poorly diagnosable mediastinal teratoma containing elements of mature pancreas tissue, nesidioblastosis, and focal hyperplasia of neuroendocrine cells in a somatically healthy 25-year-old male. The main diagnostic difficulties are associated with the asymptomatic clinical course of mediastinal teratomas that are usually incidentally discovered during X-ray for other conditions. The pathology is characterized by pronounced morphological heterogeneity of the tumor; if the morphologist is not sufficiently qualified, this often results in a false-positive conclusion of neuroendocrine carcinoma, which, in turn, leads to an inadequate amount of treatment and a wrong prognosis in the patient. Therefore, for verification of the diagnosis, histological specimens should be examined by experts of institutions experienced in morphological differential diagnosis. In this case, an immunohistochemical study of the tumor for insulin, cytokeratins, and markers of neuroendocrine differentiation as well as measurement of the proliferation index Ki-67 in several areas are the key tests. This pathology is extremely rare, which leads to numerous misdiagnoses.

Published: December 2017

Contiguous gene syndromes (CGS) are the disorders caused by chromosomal abnormalities: deletions, duplications, or other complex rearrangements that alter gene dosage. Initially, before their chromosomal nature is elucidated, they may be misdiagnosed as monogenic disorders depending on the leading clinical symptom cluster. The altered chromosomal region in individuals with this condition is typically less than 5 Mb in size and sometimes cannot be identified by conventional karyotyping. Patients present with signs of the diseases associated with each individual monogenic disorder. The Xp21-linked genetic syndrome, or glycerol kinase deficiency (GKD) (MIM 300474), is an example of this syndrome [1–3]. The genes coding for glycerol kinase (GK), congenital adrenal hypoplasia (NR0B1), and dystrophin (DMD) follow each other in the Xp21.2—p21.3 region. Deletions of an X-chromosome region may cause several monogenic disorders in one patient, including primary adrenal insufficiency and hypogonadotropic hypogonadism as a result of deletion in the NR0B1 gene, Duchenne muscular dystrophy (or a milder form, Becker muscular dystrophy) resulting from deletion in the dystrophin gene, and mental retardation as a result of deletion in the glycerol kinase gene.
We report a case of concomitant myopathy, adrenal insufficiency, and mental retardation linked with deletion of Xp21.
Case-control study of the safety of total thyroidectomy for amiodarone-induced thyroiditis
Authors: Dickfos Marilla , Franz Robert
Published: December 2017

Цель. Амиодарон является жизненно важным лекарством, но способным провоцировать развитие амиодарон-индуцированного тиреотоксикоза (АмИТ) – угрожающего жизни побочного эффекта, который может вызвать серьезную сердечную дисфункцию и привести к развитию сердечной недостаточности. Небольшая часть пациентов не отвечает на терапию, а степень сердечной дисфункции у них продолжает расти. Больным из этой группы обычно выполняют тотальную тиреоидэктомию. Без хирургического удаления щитовидной железы смертность этих пациентов достигает 30–50%. Хотя хирургические вмешательства считаются более безопасными у эутиреоидных пациентов, продление медикаментозной терапии может привести к ухудшению сердечной функции и повышению хирургических рисков. Исследование направлено на изучение безопасности хирургического лечения АмИТ у пациентов, для которых медикаментозная терапия оказалась неэффективной.
Методы. Мы проводили сравнение пациентов, подвергшихся хирургическому лечению АмИТ, и пациентов, перенесших тотальную тиреоидэктомию по другим показаниям. Нами были проанализированы демографические данные пациентов, сведения об их ASA-статусах, весе щитовидной железы, осложнениях (возникших в результате хирургического лечения и наркоза) и частоте тиреотоксического криза.
Результаты. Это исследование позволило продемонстрировать, что тотальная тиреоидэктомия является относительно безопасной процедурой для лечения АмИТ, который не поддается медикаментозной терапии. Выявлена сходная частота развития осложнений у пациентов двух групп.
Выводы. Тотальная тиреоидэктомия является безопасной процедурой и может выполняться у пациентов с АмИТ.
Актуальность. Наши данные дают хирургам возможность объяснить пациенту реальные риски при данной операции. Они также обеспечивают лечащему врачу уверенность в безопасности процедуры у больных с амиодарон-индуцированным тиреотоксикозом.

Authors: Białek Magdalena
Published: December 2017

The tasks that the contemporary teachers of foreign languages face as well as the roles that they should assume as leaders of the educational process are of complex nature. This complexity is a result of numerous social changes and transformational processes. In response to these changes, educators’ roles keep being redefined so that the tasks that the teachers take up could be as effective as possible in the given time and space. These modified roles of teachers are the subject of this article. In the theoretical part, the results of the analysis of the literature on foreign language teaching are presented, with the focus on teacher roles and tasks. The analysis indicates the main development tendencies in foreign language teaching after the breakthrough caused by the communicative approach. The empirical part presents the outcome of research into how contemporary middle school students identify the roles and tasks of the teacher of German. The results of the study may contribute to the scholarly reflection on the role of the teacher in the foreign language teaching process.

Modeling Simultaneous Multiple Goal Pursuit and Adaptation in Consumer Choice
Authors: Swait Joffre , Argo Jennifer , Li Lianhua
Published: December 2017

Goals are constructs that direct choice behavior by guiding a decision maker toward desirable (or away from undesirable) end states. Often, consumers are motivated to satisfy multiple goals within a single choice. Although previous research has recognized this possibility, it has not directly formulated models of choice as a multigoal problem. The authors develop such a model, referred to as the multiple-goal-based choice model, which incorporates (1) simultaneous multiple goal pursuit and (2) context-driven goal adaptation but (3) does not require a priori identification of the number or nature of the goals. Goal adaptation within a single choice instance, allied to repeated choices, is the key to empirical identification of multiple latent goals. The proposed model is tested and supported using discrete choice experimental data on digital cameras through multiple validation exercises. The model can lead to significantly different policy implications with regard to consumers’ valuation for new product designs, compared with extant utility-based choice models.
Proteolytic Processing of Neurexins by Presenilins Sustains Synaptic Vesicle Release

Proteolytic processing of synaptic adhesion components can accommodate the function of synapses to activity-dependent changes. The adhesion system formed by neurexins (Nrxns) and neuroligins (Nlgns) bidirectionally orchestrate the function of presynaptic and postsynaptic terminals. Previous studies have shown that presenilins (PS), components of the gamma-secretase complex frequently mutated in familial Alzheimer's disease, clear from glutamatergic terminals the accumulation of Nrxn C-terminal fragments (Nrxn-CTF) generated by ectodomain shedding. Here, we characterized the synaptic consequences of the proteolytic processing of Nrxns in cultured hippocampal neurons from mice and rats of both sexes. We show that activation of presynaptic Nrxns with postsynaptic Nlgn1 or inhibition of ectodomain shedding in axonal Nrxn1-β increases presynaptic release at individual terminals, likely reflecting an increase in the number of functional release sites. Importantly, inactivation of PS inhibits presynaptic release downstream of Nrxn activation, leaving synaptic vesicle recruitment unaltered. Glutamate-receptor signaling initiates the activity-dependent generation of Nrxn-CTF, which accumulate at presynaptic terminals lacking PS function. The sole expression of Nrxn-CTF decreases presynaptic release and calcium flux, recapitulating the deficits due to loss of PS function. Our data indicate that inhibition of Nrxn processing by PS is deleterious to glutamatergic function.

SIGNIFICANCE STATEMENTTo gain insight into the role of presenilins (PS) in excitatory synaptic function, we address the relevance of the proteolytic processing of presynaptic neurexins (Nrxns) in glutamatergic differentiation. Using synaptic fluorescence probes in cultured hippocampal neurons, we report that trans-synaptic activation of Nrxns produces a robust increase in presynaptic calcium levels and neurotransmitter release at individual glutamatergic terminals by a mechanism that depends on normal PS activity. Abnormal accumulation of Nrxn C-terminal fragments resulting from impaired PS activity inhibits presynaptic calcium signal and neurotransmitter release, assigning synaptic defects to Nrxns as a specific PS substrate. These data may provide links into how loss of PS activity inhibits glutamatergic synaptic function in Alzheimer's disease patients.

Abstract:

Introduction: Health awareness plays an important role in our life, which contains attitudes as well behavioural components. Social factors influencing health awareness were the basis of many previous investigations, measuring the effect of demographical and psychological factors. However, investigation of these factors usually happened with separated questions. Aim: The aim of the present study is to test a new questionnaire, which measures health behaviour and attitudes related to health awareness. Method: In present study, the attention was drawn to the introduction of a new questionnaire related to health behaviour, attitudes toward health awareness and factors influencing those and measured on population in Debrecen (SHTE 2017; n = 256). Results: the new measurement proved to be reliable based on Cronbach α analysis. This was created on the basis of focus content analysis of group conversations with 10 subscales and 35 items. Conclusions: It can be stated that gender, father’s educational level, objective and subjective financial status has a significantly negative effect; while sport, subjective health and fitness as well as subjective religiosity have a significantly positive effect which reflects previous findings and confirm the reliability of our questionnaire.

A laktátdehidrogenáz (LDH) prognosztikai jelentősége az onkológiában
Authors: Deme Dániel , Telekes András
Published: December 2017

Abstract:

Glycolysis is increased in most of the malignant cells, providing the largest proportion of energy needed for cell proliferation. Lactate dehydrogenase (LDH) catalyses the reversible process of pyruvate to lactate in anaerobic condition. LDHA isoenzyme expressed mainly by malignant cells, significantly increases lactate formation. Lactate induces the proliferation of oxygenated malignant cells, angiogenesis, and inhibits the innate and adaptive immune responses. Baseline serum LDH elevation correlates with shorter survival. The authors review the relevant studies exploring the correlation between LDH elevation and the prognosis of malignant diseases. Orv Hetil. 2017; 158(50): 1977–1988.
Acetazolamid orális alkalmazása mellett jelentkező chorioidealeválás két esete: ismert idioszinkráziás hatás szokatlan megjelenési formája?

Published: December 2017

Abstract:

Sulpha drugs are widely employed in medicine for various diseases and disorders. During the last several decades, numerous papers had been published on supra ciliary and posterior choroidal effusion likely presenting as an idiosyncratic effect of these drugs especially of acetazolamide. In each publication, the effusion was associated with either an acute angle-closure glaucoma or transitory myopia or both of these as leading symptoms. In the current publication, authors report on two cases where the acetazolamide-induced choroidal effusion was an accidental finding without either a myopic shift in refraction or an acute elevation in intraocular pressure. To our best knowledge, ours is the first report in the literature describing this unusual, “silent” form of a sulpha drug-induced choroidal effusion. Since the choroidal involvement may vary in size and location, and is not necessarily associated with acute glaucoma and myopia, one can assume that a considerable amount of acetazolamide-related ocular side-effects will not be discovered. The above case report aims to draw the attention of other specialities to the need for ophthalmic examination for their patients taking sulpha drugs with acute visual deterioration.

Expanding Role of Technology in Foreign Language Teacher Education Programs
Authors: Luke Christopher , Britten Jody
Published: December 2017

The advent of the technological era continues to impact foreign language education in numerous ways. Current and future foreign language educators must learn to effectively and meaningfully merge technology with instructional practices and activities. This responsibility necessitates a thorough and realistic understanding of the various functions, uses, strengths, and limitations of technology in education settings. A logical starting place for teachers to gain knowledge and expertise with technology is teacher education programs at the college level. The purposes of this article are (a) to highlight and explain some of the expanding roles and affordances of technology in a collegiate foreign language education program and (b) to encourage continued research and development of instructional technology in teacher education programs. Rather than focusing on one particular class, this article illustrates how technology can be an integral and cohesive programmatic component interwoven throughout teacher candidates' entire academic careers.

Exploring the Information Source Preferences Among Canadian Adult Golf League Members
Authors: Davies Melissa , Gray Dianna
Published: December 2017

With an aging demographic, and the abundance of physical inactivity in Canada, sport professionals need to understand how best to recruit and retain adults in sport and recreational activities, namely, golf leagues.  Canadian golf league participants (N = 419; Mage = 62 years old) completed an online survey detailing their propensity to utilize a variety of information sources prior to making the decision to join a golf league.  Results from a principal component analysis of a revised Information Sources Inventory, suggested that golfers in this sample were most likely to utilize Personal and Social sources of information associated with their league participation decision.  While no differences emerged in information source preferences across Age or levels of Involvement, women (m = 4.12, SD = 1.30) were significantly more likely to utilize Public information sources than were men (m = 3.64, SD = 1.26).  Implications from the information source preferences are discussed with the goal of generating more effective marketing strategies to recruit new golfers, lapsed golfers, or golfers who do not currently engage in league play.
Qualitätssicherung leittechnischer Systeme
Authors: Hauff Thomas
Published: December 2017

Die Automatisierungstechnik in der Prozessindustrie hat einen Wandel von proprietärer Technik zu IT-Komponenten durchlaufen. Diese Technologie bietet neue Chancen, zeigt aber auch Risiken für die kostenintensive und langlebige Basisautomatisierung. Der NAMUR AK 2.11 "Industrielle IT/Leittechnik" hat zu diesem Thema die NAMUR-Empfehlung NE 121 "Qualitätssicherung leittechnischer Systeme" erarbeitet. Die NE 121 betrachtet im Wesentlichen vier Aspekte: - Die Qualitätssicherung des Herstellers, um erforderliche Produkteigenschaften sicherzustellen, - ein definiertes Lebenszyklusmanagement, um die Folgekosten einer Investition berücksichtigen zu können, - die technische Evaluierung, um die Produkte und Angebote der Hersteller vergleichen und bewerten zu können, - die Anforderungen an die Anwender der Systeme, um die erforderliche Spezifikations- und Beurteilungskompetenz der Anwender sicherzustellen. Die Entwicklung geeigneter Standards erfordert die Zusammenarbeit und den Dialog zwischen allen Beteiligten. Dazu sind Weiterentwicklungen auf Anwenderseite und auf Herstellerseite erforderlich.
Kommunikationstechnik in der Prozessautomatisierung - mehr als Feldbus
Authors: Schwibach Martin
Published: December 2017

Die Kommunikationstechnik gewinnt in den letzten Jahren in der Prozessautomatisierung immer mehr an Bedeutung. Nachdem jahrzehntelang nach Ablösung von pneumatischen Systemen das elektrische 4-20 mA Einheitssignal die kommunikationstechnische Basis für fast alle automatisierungstechnischen Anwendungen war, setzte in den 90er-Jahren mit der explosionsartigen Entwicklung der IT auch in der Automatisierungstechnik ein Wandel ein. Dieser hat bis heute die Systemarchitekturen nachhaltig verändert. Schlagworte wie HART, OPC oder Feldbus drängten sich dabei immer mehr in den Mittelpunkt. Heute sind vernetzte Automatisierungssysteme Standard. Eine systemübergreifende Kommunikation, die horizontale und vertikale Informationsintegration oder der Fernzugriff gehören zum Alltag. Zuverlässigkeit und Verfügbarkeit, Nachhaltigkeit und Investitionssicherheit, dies sind die Rahmenbedingungen, die jede neue Lösung erfüllen muss, um erfolgreich in verfahrenstechnischen Anlagen eingesetzt werden zu können. Was bedeutet dies konkret? Durch den Einsatz von modernen Kommunikationstechnologien dürfen bislang gesetzte Anforderungen an bestehende Übertragungstechnologien nicht umgangen werden. Dies gilt insbesondere in Bezug auf funktionale Sicherheit, Verfügbarkeit, Explosionsschutz und EMV. Auch weiterreichende Anforderungen z. B. an Interoperabilität, IT Security oder Diagnose sind zu beachten. Die NAMUR hat in den vergangenen Jahren hierzu eine Vielzahl von Papieren veröffentlicht, die als Anhaltspunkt dienen können. Die Potentiale für den Einsatz von modernen Kommunikationstechnologien liegen eindeutig da, wo konventionelle Lösungen bislang unwirtschaftlich oder ungeeignet waren. Es sind also neue, wertschöpfende Anwendungen und es ist nicht allein der störungsfreie Betrieb von Systemen, die den Einsatz und die Weiterentwicklung von kommunikationstechnischen Strukturen in der Automatisierungstechnik rechtfertigen. Der Nutzen für den Anwender muss dabei stets im Mittelpunkt stehen.

Unscripting Curriculum: Toward a Critical Trans Pedagogy
Authors: KEENAN HARPER BENJAMIN
Published: December 2017

In this essay, Harper B. Keenan draws on his own experience as a white queer and trans educator to consider the meaning of a critical trans pedagogy. Amid dissonant narratives of equal rights and subjection, he explores how his classroom teaching is shaped by his own experience of gender conditioning as well as by the contemporary political climate surrounding trans identity. Keenan argues that a critical trans pedagogy requires unscripting and must necessarily support children in constructing new knowledge.
“We Are All for Diversity, but . . .”: How Faculty Hiring Committees Reproduce Whiteness and Practical Suggestions for How They Can Change
Authors: SENSOY ÖZLEM , DiANGELO ROBIN
Published: December 2017

Despite stated commitments to diversity, predominantly White academic institutions still have not increased racial diversity among their faculty. In this article Robin DiAngelo and Özlem Sensoy focus on one entry point for doing so—the faculty hiring process. They analyze a typical faculty hiring scenario and identify the most common practices that block the hiring of diverse faculty and protect Whiteness and offer constructive alternative practices to guide hiring committees in their work to realize the institution's commitment to diversity.

O objetivo do presente estudo foi investigar, in vitro, o padrão de fratura em dentes com pino de fibra de vidro (PFV) anatomizado e fixado com diferentes agentes cimentantes. Foram utilizados 30 dentes bovinos mandibulares unirradiculares. As raízes foram tratadas endodonticamente e divididas aleatoriamente em dois grupos, de acordo com o agente cimentante utilizado, em G1: cimento resinoso autoadesivo (RelyX U200-3M ESPE); G2: cimento resinoso convencional (Allcem-FGM). Após a anatomização e cimentação dos pinos, os espécimes foram armazenados em estufa, a 37ºC, por sete dias. Em seguida, foi realizada a secção das raízes, sob irrigação constante, obtendo-se de cada raiz seis fatias de 1 mm de espessura, totalizando 180 corpos de prova. O teste de resistência à extrusão (push-out) foi realizado em todos os espécimes, e posteriormente, os corpos de prova foram observados em microscópio ótico de luz, para avaliar os tipos de fratura. O tipo de fratura mais frequente em ambos os grupos foi a coesina em dentina (G1 = 32,2%; G2 = 30%). Observou-se frequência estatisticamente maior de falhas adesivas entre dentina e cimento no grupo G2 (P = 0,007). Além disso, detectou-se frequência estatisticamente mais elevada (P = 0,027) de fratura coesiva em dentina no terço cervical (38,3%) quando comparado ao terço apical (20,0%). Os achados sugerem que o cimento autoadesivo (RelyX U200-3M ESPE) apresentou resultados mais favoráveis quando da análise do padrão de fraturas.

Pacientes oncológicos pediátricos podem se beneficiar de tratamento odontológico antes e durante a terapia do câncer, pois tanto a quimioterapia quanto a radioterapia, podem causar alterações nos tecidos sadios da cavidade oral. O objetivo deste projeto foi identificar lesões e alterações bucais em pacientes pediátricos oncológicos cadastrados na Rede Feminina de Combate ao Câncer de Maringá/PR e aplicar métodos de atenção primária e curativa. O projeto recebeu aprovação do Comitê de Ética em Pesquisa do UniCesumar (Protocolo nº 1.474.425). Foram realizadas 22 visitas domiciliares a esses pacientes, com idades variando entre dois e 14 anos. Nas visitas foram incentivados os hábitos de higiene bucal e dieta saudável, e fornecida uma escova dental para cada uma. Aos pacientes que necessitavam de tratamento curativo, foi oferecido tratamento na Clínica de Odontologia do UniCesumar. Neste estudo foi relatado que os pacientes apresentaram náusea, disfagia, mucosite oral, xerostomia, disgeusia e candidíase oral, durante o tratamento oncológico o qual foram submetidas. Com isso foi determinado que a presença do cirurgião-dentista na equipe multidisciplinar oncológica é fundamental.

The present study deals with preliminary assessment of adolescents’ with Pectus excavatus (PE) personal emotional characters of selt-attitude prior to and after surgical treatment. PE is a congenital defect manifesting in retraction of sternum and cartilaginous portions of the ribs into the rib-cage. It constitutes about 90% of the entire number of cases of congenital pathology of the chest, its rate as high as 1-8 per 1000 neonates. The only method of treatment for this pathology is surgical operation for conservative measures can’t stop progressive deformation of the chest. The peak of this pathology coincides with adolescent period which is particularly sensitive for forming of personality. The goal of the present study is the assessment of emotional and personality features of adolescents with PE that are manifesting in peculiarities of cognitive, affective and behavioral reactivity. 26 adolescent patients aged 13 to 17 years with PE hospitalized at surgical clinic of St. Petersburg State Pediatric Medical University for subsequent primary operative elimination of this defect or recurring operation – ablation of the implant (1-4 years after the primary surgery) took part in the present study. High level of anxiety and depression associated with negative perception of their bodies prior to surgery was revealed. Urgent need for psychological assistance of these adolescents is evident as well as extension of further studies associated with peculiarities of emotional self-perception and its correlation with children-parents relationship character.
Assessment of the results of treatment of children with amblyopia associated with strabismus

Treatment of amblyopia in children with strabismus is still a difficult problem, especially in cases of disruption of binocular vision. There are also classification differences, reflected in the proposals, coming from professors E.S. Avetisov (1968) and E.E. Somov (1997). The question is how to assess the severity of amblyopia and the result of its treatment. The first author has chosen as the primary measure visual acuity, the second – binocular function. This indicator is integral and really reflects the level of functional status of the organ of vision of any child. This is a really important point, because the essential symptom of strabismic and of other origin amblyopia is impairment, detected in binocular vision. In addition, we should keep in mind the fact, that the “maturation” of central visual acuity in children is gradual and closely related to their age. After we have examined 50 children systematically attending a specialized kindergarten, we found out, that according to the criteria of E.S. Avetisov their cure is 39.8%, and according to the criteria of E.E. Somov – 12,5%. In the first case, it is a significantly inflated figure due to children with really high visual acuity and lack of binocularity. But daily practice shows that the results of high visual acuity after pleoptic therapy, not supported by the re-establishment of binocular vision, are not durable and gradually, or sometimes rapidly decrease. The study also showed that the existing methods of orthoptic treatment are not effective enough and must be improved.
EU and Mercosur vis a vis the Trade Agreement. Remarks from the institutional perspective
Authors: Querci Isabella
Published: December 2017

The member States of Mercosur are currently negotiating a Trade Agreement with the EU, as part of the process towards a comprehensive bi-regional Association Agreement. In 2016, the EU and Mercosur members exchanged offers, followed by a negotiation round. The next round will be held in October 2017; while awaiting for political developments, it is worth anticipating some challenges to come, especially from a legal perspective. Both actors have a multilayered system for decision-making, requiring the consensus of a multiplicity of governmental actors and thus enabling them to convey. Furthermore, current dialogues consider a broad range of issues, which were also covered by different EU’s agreements with other trading partners. These agreements received critiques from the civil society, which are worth to reflect upon, considering that the trade agreement is due to impact the general negotiation for the bi-regional Association Agreement. The paper develops this reflection from a twofold perspective: that of the institutional nature of EU and Mercosur and that of the democratic deficit in the overall negotiation process.

Cluster differentiation 4 (CD4) count estimation, which is not readily available in most resource poor settings in Nigeria, is an important indexdetermining commencement of antiretroviral therapy (ART). It is imperative for physicians who come in contact with these patients in such settings to recognize other parameters to evaluate these patients. The clinical correlates of diarrhea and gut parasites among human immunodeficiency virus (HIV)-seropositive patients attending our special treatment clinic were studied. Three hundred and forty consenting HIV-positive adult subjects were enrolled. Their stool and blood specimens were collected for a period of three months. Stool samples were analyzed for the presence of diarrhea and gut parasites. The patients were clinically evaluated by physical examination for the presence of pallor, dehydration, oral thrush, wasting lymphadenopathy, dermatitis, skin hyperpigmentation, and finger clubbing. Participants with diarrhea represented 14.1% of the population, while 21.5% harbored one or more parasites. In the subjects with diarrhea, 14.6% harbored gut parasites. The presence of diarrhea was associated with a low CD4 count. Clinically, oral thrush, wasting, and rashes were more reliable predictors of low CD4 count levels; whereas, the presence of pallor, dehydration, wasting, and rashes correlated with the presence of diarrhea. HIV patients presenting with pallor, dehydration, wasting, and rashes should be evaluated for the presence of diarrhea. The clinical variables associated with low CD4 count in this study may guide commencing antiretroviral therapy in resource poor settings.
