A tumor-specific cellular environment at the brain invasion border of adamantinomatous craniopharyngiomas.

Craniopharyngiomas (CP) are benign epithelial tumors of the sellar region and can be clinicopathologically distinguished into adamantinomatous (adaCP) and papillary (papCP) variants. Both subtypes are classified according to the World Health Organization grade I, but their irregular digitate brain infiltration makes any complete surgical resection difficult to obtain. Herein, we characterized the cellular interface between the tumor and the surrounding brain tissue in 48 CP (41 adaCP and seven papCP) compared to non-neuroepithelial tumors, i.e., 12 cavernous hemangiomas, 10 meningiomas, and 14 metastases using antibodies directed against glial fibrillary acid protein (GFAP), vimentin, nestin, microtubule-associated protein 2 (MAP2) splice variants, and tenascin-C. We identified a specific cell population characterized by the coexpression of nestin, MAP2, and GFAP within the invasion niche of the adamantinomatous subtype. This was especially prominent along the finger-like protrusions. A similar population of presumably astroglial precursors was not visible in other lesions under study, which characterize them as distinct histopathological feature of adaCP. Furthermore, the outer tumor cell layer of adaCP showed a distinct expression of MAP2, a novel finding helpful in the differential diagnosis of epithelial tumors in the sellar region. Our data support the hypothesis that adaCP, unlike other non-neuroepithelial tumors of the central nervous system, create a tumor-specific cellular environment at the tumor-brain junction. Whether this facilitates the characteristic infiltrative growth pattern or is the consequence of an activated Wnt signaling pathway, detectable in 90% of these tumors, will need further consideration.

Health facility environment as humanization strategy care in the pediatric unit: systematic review

Objective: To identify and analyze the production of knowledge about the strategies that health care institutions have implemented to humanize care of hospitalized children. Method: This is a systematic review conducted in the Virtual Health Library - Nursing and SciELO, using the seven steps proposed by the Cochrane Handbook. Results: 15 studies were selected, and strategies that involved relationship exchanges were used between the health professional, the hospitalized child and their families, which may be mediated by leisure activities, music and by reading fairy tales. We also include the use of the architecture itself as a way of providing welfare to the child and his/her family, as well as facilitating the development of the work process of health professionals. Conclusion: Investments in research and publications about the topic are necessary, so that, the National Humanization Policy does not disappear and that the identified strategies in this study do not configure as isolated and disjointed actions of health policy.

Method: A descriptive, analytical and cross-sectional study, for the cross-cultural adaptation and validation of the psychometric properties of the scale. The study participants were 236 nurses from two hospitals in the regions of Lisbon and Vale do Tejo. Results: The 0.92 Cronbach’s alpha was obtained for overall reliability and support of a five-dimension structure. Conclusion: The excellent quality of adjustment of analysis confirms the validity of the adapted version to hospital care settings, although there was no total coincidence of items in the five dimensions


Virtual Environment: assistance in nursing care for the deaf based on the protocol of Primary Care

Objective: Presenting a Virtual Environment (VE) based on the Protocol of Treatment of Hypertension and Diabetes Mellitus type 2, used in Primary Care for evaluation of dietary habits in nursing consultations. Method: An experimental study applied by two nurses and a nurse manager, in a sample of 30 deaf patients aged between 30 and 60 years. The environment was built in Visual Basic NET and offered eight screens about feeding containing food pictures, videos in Libras (Brazilian sign language) and audio. The analysis of the VE was done through questionnaires applied to patients and professionals by the Poisson statistical test. Results: The VE shows the possible diagnostics in red, yellow, green and blue colors, depending on the degree of patients’ need. Conclusion: The environment obtained excellent acceptance by patients and nurses, allowing great interaction between them, even without an interpreter. The time in consultation was reduced to 15 minutes, with the preservation of patient privacy.

The work environment and leadership in nursing: an integrative review

Objective: To investigate the relationship between the work environment and leadership in nursing. Method: An integrative review of literature which was based on data from LILACS, PubMed, CINAHL and the SciELO portal for journals covering the period from January to April 2013. The inclusion criteria were: the indexing of research covering leadership exercised by nurses over a team and whether the research was available in English, Spanish or Portuguese. Results: The sample consisted of 12 articles that met the criteria. Conclusion: The results showed that leadership had an impact on the work environment. However, no studies were found that showed the influence of the working environment on leadership in nursing.

Professional knowledge in primary health care of the person/family in mental distress: Le Boterf perspective

Aim of this study was to identify knowing-doing actions constituted the practice of Family Health (FH), in view of nurses in relation to the person and family care in mental distress in terms of professional knowledge of Le Boterf. Method: Descriptive exploratory qualitative study, to deepen contruction of nurse in FH. The survey was conducted in 3 Units FH. Result: Doing a thematic analysis, came to the following categories: “Knowing how to act and react with relevance”; “Knowing how to combine resources and mobilize them in a professional context”; “Knowing how to interact with multiple knowledges”; “Knowing how to transpose”; “Knowing how to learn and knowing how to learn to learn”; “Knowing how to engage”. Final considerations: the greatest difficulty was "be able to transpose," and that the daily demand of the FH teams requires a lot of this knowledge. Little transposition of knowing-doing in real situations has been verified.

Facilitators of the transition process for the self-care of the person with stoma: subsidies for Nursing

OBJECTIVE To know the facilitating factors of the transition process from dependency to the self-care of people with a stoma. METHOD This is a descriptive study of qualitative approach, including 27 people with permanent stomas due to cancer. The data were collected through semi-structured interviews and submitted to content analysis based on the Transition Theory as theoretical reference. RESULTS The self-care facilitators related to the person were the positive significance of ostomy; the preparation for this experience already in the preoperative period; emotional stability; faith; religiousness; and a sense of normalcy acquired from a next image similar to the previous one. The facilitators related to the community were the following: receiving equipment for free from the government; support from family and the multidisciplinary team, especially the nurses; and having contact with other people with stomata. CONCLUSION The results allow that nurses develop strategies to help people with stomata to resume their self-care.

Perioperative thirst: an analysis from the perspective of the Symptom Management Theory

A theoretical study aimed to analyze the existing knowledge in the literature on the perioperative thirst symptom from the perspective of Symptom Management Theory, and supplemented with the experience of the study group and thirst research. Thirst is described as a very intense symptom occurring in the perioperative period, and for this reason it cannot be ignored. The Symptom Management Theory is adequate for understanding the thirst symptom and is a deductive theory, focused on the domains of the Person, Environment and Health / Illness Status, as well as on the dimensions of Experience, Management Strategies and Symptom Outcomes. Using the theory leads us to consider perioperative thirst in its multifactorial aspects, analyzing the interrelation of its domains and dimensions in order to draw attention to this symptom that has been insufficiently valued, recorded and treated in clinical practice.

O Impacto Fiscal Decorrente do processo de Rememoração de Activos Fixos Tangíveis

O objectivo deste estudo consiste em evidenciar a politica contabilística de revalorização de activos fixos tangíveis e o seu impacto numa entidade, principalmente a nível da tributação dos rendimentos. A abordagem é direccionada para o meio empresarial cabo-verdiano onde se pretende dar a conhecer o enquadramento legal e fiscal existente, assim como ilustrar com um caso prático. O trabalho foi preparado com base em consulta de bibliografia especializada, de normativos estabelecidos no país e ainda a recolha de dados práticos sobre o tema e entrevistas com profissionais na área. Partimos do geral para o particular, isto é, começamos por trabalhar o conteúdo dos activos fixos tangíveis no geral, para posteriormente entrarmos no objecto de estudo: a revalorização dos activos fixos tangíveis, e assim dar a conhecer os impactos que este tema traz para uma entidade. O trabalho inicia com um enquadramento teórico de conceitos relacionados com os fenómenos que levam com que um bem perca valor ao longo dos anos, assim como outras matérias directamente ligadas às revalorizações (exemplo da manutenção de capital físico e financeiro). É feita uma abordagem normativa e conceitual geral sobre os activos fixos tangíveis: o reconhecimento, a mensuração inicial e subsequente, a divulgação e o Desreconhecimento. É uma abordagem comparativa com o sistema contabilístico anterior (Plano Nacional de Contabilidade). No tratamento da mensuração subsequente dos activos fixos tangíveis introduzimos o estudo da Revalorização do Activos Fixos Tangíveis, referindo as normas contabilísticas e as leis fiscais relacionadas e os impactos que traz para a empresa. aim of this research consist in show evidences about the accounting policy of value of revalorization of Tangible Assets and its impact in an entity, mainly in terms of taxation incoming. The approach is directed to the Cape-Verdean enterprise environment where is intended to give to know the legal and tax framing, as well illustrate with a practical case. This task was prepared based on specialized bibliographic researches, of normative established in the country and also the collecting of practical data about the theme and interviews with professionals in the area. We start from general to particular, that is, we started working on the contents of Tangible Assets in general, to later on get into the study object: the revalorization of Tangible Assets and thus give to know the impacts that this brings to an entity. The task tarts with the theoretical framing of concepts related with the phenomenon that lead one good lose its value along the years, as well other material goods directly connected to revalorization (example of maintenance of physical and financial capital). It is made a normative and general conceptual approach about the Tangible Assets: the recognizing, the measurable initiate and subsequently, the divulgation and the unknown. It is a comparative approach with the previous accounting system (National Accounting Plan). In the treatment of the measurable of Tangible Assets we introduced the study of Revalorization of Tangible Assets, referring the accounting rules and the related fiscal laws and the impacts that bring to the company.

Gene-environment interactions of selected pharmacogenes in arterial hypertension.

Hypertension affects approximately 1 billion people worldwide. Owing to population aging, hypertension-related cardiovascular burden is expected to rise in the near future. In addition to genetic variants influencing the blood pressure response to antihypertensive drugs, several genes encoding for drug-metabolizing or -transporting enzymes have been associated with blood pressure and/or hypertension in humans (e.g., ACE, CYP1A2, CYP3A5, ABCB1 and MTHFR) regardless of drug treatment. These genes are also involved in the metabolism and transport of endogenous substances and their effects may be modified by selected environmental factors, such as diet or lifestyle. However, little is currently known on the complex interplay between environmental factors, endogenous factors, genetic variants and drugs on blood pressure control. This review will discuss the respective role of population-based primary prevention and personalized medicine for arterial hypertension, taking a pharmacogenomics' perspective focusing on selected pharmacogenes.

Lost in translation : euro-compatibility, legal security, and the autonomous implementation of EU law in Switzerland

This article presents the legislative and judicial practice relating to the "autonomous implementation" of EU law in Switzerland. Given that "euro-compatibility" is the central consideration behind this legislative policy, one would expect Swiss authorities to have devised legislative and hermeneutical techniques guaranteeing high fidelity to EU "mother law". That is not the case, however, and as this article shows much is lost in the translation from EU to Swiss Law

Intimate partner violence against pregnant women: the environment according to Levine's nursing theory

Abstract OBJECTIVE Analyzing the elements that compose the environment of pregnant women who have experienced intimate partner violence in the light of Levine's Nursing Theory. METHOD A qualitative, descriptive study conducted from September to January 2012, with nine pregnant women in a Municipal Health Center in Rio de Janeiro. The interviews were semi-structured and individual. The theoretical framework was based on Levine's Nursing Theory. RESULTS Thematic analysis evidenced the elements that composed the external environment, such as violence perpetrated by intimate partners before and during pregnancy, violence in childhood and adolescence, alcohol consumption and drug use by the partner, unemployment, low education and economic dependency, which affected health and posed risks to the pregnancy. CONCLUSION Violence perpetrated by an intimate partner was the main external factor that influenced the internal environment with repercussions on health. This theory represents a tool in nursing care which will aid in detecting cases and the fight against violence.

Compensation for environmental damages under international law

ABSTRACT The purpose of this research is to clarify the contribution of international dispute adjudication mechanisms in regard to environmental protection. Most specifically, the study aims to identify and develop the criterion adopted by the international judge in relation to the compensation for environmental damages. In this perspective, the study identifies some gaps between international responsibility and environmental protection interests. The premise sustained all along the study is that compensation is determinant to conciliate environmental prerogatives with mechanisms of international adjudication, in particular the system of international responsibility. Supported by the analysis of treaties, international decisions and secondary sources, the thesis defends the idea that some elements of international law allow the adjudicator to adapt the compensation to attend certain environmental interests, creating a new approach which was entitled 'fair compensation'. The antithesis of this approach is the idea that compensation in international law is limited exclusively to the strict reparation of the material losses incurred by the victim. As a synthesis, the study defends the specificity of environmental damages in relation to other kind of damages that are subject to compensation under international law. The measure upon which compensation for environmental damages could be classified as a specific type of damage under international law remains to be determined. The main conclusion of the study is that the existing standard of compensation defined by the theory and practice of international law is impossible to be strictly respected in cases involving environmental damages. This limitation is mainly due to the complexity of the notion of environment, which is constantly conflicting with the anthropologic view of legal theory. The study supports the idea that the establishment of a 'fair compensation' which takes into account the political, legal and technical context of the environmental damage, is the best possible approach to conciliate internationally responsibility and environmental interests. This could be implemented by the observance of certain elements by the international judge/arbitrator through a case-by-case analysis.
