Objectivos: Determinar a possibilidade de avaliação não invasiva da pressão venosa central (PVC) através da análise da veia cava inferior (VCI), obtida por ecocardiografia transtorácica (ETT). Desenho: Estudo prospectivo com 3 anos de duração. Local: Unidade de Cuidados Intensivos Polivalente(UCIP) de 16 camas. Métodos: Estudados doentes admitidos numa UCIP nos quais se avaliou a PVC em simultâneo com exame ETT que, para além da visualização da VCI, consistiu na obtenção da dimensão das cavidades cardíacas e função sistólica do ventrículo esquerdo. Para a correlação foram utilizados testes estatísticos paramétricos e não paramétricos. Resultados: Admitidos 560 doentes com registo simultâneo de PVC e ETT e incluídos 477 doentes em que foi possível visualizar a VCI, com idade média de 62,6 ±17,3 anos, média de internamento de 11,9 ± 18,7 dias, um índice APACHE II médio de 23,9 ± 8,9 e SAPS II médio de 55,7 ± 20,4. Por análise de regressão linear verificou-se uma relação entre a PVC e a dimensão máxima da VCI (p=0,013), o índice da VCI (p=0,001) e a presença de ventilação mecânica (p=0,002). A correlação linear entre a PVC e a dimensão máxima da VCI e respectivo índice foi de 0,34 e 0,44. Por teste de qui-quadrado, verificou-se uma relação estatisticamente significativa entre os seguintes intervalos de valores: índice da VCI <25% e PVC> 13mmHg; índice da VCI entre 26 e 50% e PVC entre 8 e 12mmHg; índice da VCI> 51% e PVC> 7mmHg; dimensão máxima da VCI> 20mmHg e PVC> 13 mmHg; dimensão máxima da VCI> 10mm e PVC> 7mmHg. Nos doentes com dilatação do ventrículo direito (VD) observou-se uma relação mais fraca entre a PVC <7mmHg e a dimensão máxima da VCI <10mm; nos doentes admitidos por exacerbação de doença pulmonar crónica verificou-se uma correlação fraca entre a PVC <7mmHg e o índice da VCI> 50%. A dimensão máxima da VCI, mas não o seu índice, correlacionou-se com a dilatação do VD e AD. Conclusões: A análise da VCI por ETT revelou-se útil na avaliação qualitativa da PVC em doentes admitidos numa UCIP. Em doentes com dilatação do VD e admitidos por exacerbação de doença pulmonar crónica, os métodos avaliados não foram fidedignos para valores baixos de PVC. A dilatação da VCI traduz melhor a cronicidade da doença, enquanto o índice da VCI reflecte melhor o estado de volemia.

INTRODUÇÃO: A doença de Chagas permanece como grave problema de saúde pública na América Latina, mesmo com o controle de sua transmissão. Esse estudo avaliou a prevalência da doença de Chagas no distrito de Serra Azul, Centro-Oeste de Minas Gerais, identificando as anormalidades eletrocardiografias dos indivíduos com sorologia positiva. MÉTODOS: A sorologia para doença de Chagas foi realizada em 676 indivíduos (48% da população). O exame clínico e o eletrocardiograma (ECG) foram realizados na população sorologicamente positiva. Selecionou-se um grupo controle para comparação dos dados do ECG. RESULTADOS: A população estudada residia principalmente em área rural, com baixo nível sóciocultural. Quatorze indivíduos foram positivos, com prevalência de 2,1%. Os indivíduos chagásicos eram de faixa etária mais avançada (67 vs 39 anos; p < 0,001). As anormalidades ao ECG nos chagásicos foram frequentes (79%). O ECG dos soropositivos mostrou maior prevalência de extrassístoles ventriculares, distúrbio da condução do ramo direito isolado ou associado ao bloqueio da divisão ântero-superior em relação ao grupo controle. CONCLUSÕES: A prevalência da doença de Chagas no distrito de Serra Azul foi de 2,1%. Os soropositivos estavam em faixa etária mais elevada, sugerindo controle da transmissão. As anormalidades eletrocardiográficas foram frequentes, predominando distúrbio de condução do ramo direito.

This study specifically addresses the situation of minority shareholders after the transfer of control in an listed company. The various underlying interests and reasons that shareholders have for investing in a company can demonstrate shareholders’ reasoning for taking radically different positions on issues relating to the transfer of control of the referred company. This study analyses the current legal system in Portugal and in the European Union in order to assess whether, in the event of a takeover bid of a listed company where there is a transfer of control, minority shareholders have the same appraisal rights as other shareholders to sell their shares and leave the company. The study then examines the European Court of Justice decision on whether a general principle of equal treatment of minority shareholders exists upon a transfer of control (Audiolux) and the Portuguese Securities Market Commission decision regarding the delisting of Brisa - Autoestradas de Portugal, S.A. based on the principle of investor protection. The study concludes that although the principle of equality amongst shareholders has made progress in the European legal system e.g. it is laid down in Directive 2004/25/EC of 21 April 2004 on takeover bids and the Portuguese Securities Market Code, there is also a need for further improvement, which can be accomplished by allowing minority shareholders to exercise an appraisal right in similar unregulated situations.

Ne bis in idem, understood as a procedural guarantee in the EU assumes different features in the AFSJ and in european competition law. Despite having a common origin (being, in both sectors the result of the case law of the same jurisdictional organ) its components are quite distintic in each area of the integration. In the AFSJ, the content of bis and idem are broader and addressed at a larger protection of individuals. Its axiological ground is based on the freedom of movements and human dignity, whereas in european competition law its closely linked to defence rights of legal persons and the concept of criminal punishment of anticompetitive sanctions as interpreted by the ECHR´s jurisprudence. In european competition law, ne bis in idem is limited by the systemic framework of competition law and the need to ensure parallel application of both european and national laws. Nonetheless, the absence of a compulsory mechanism to allocate jurisdiction in the EU (both in the AFSJ and in the field of anti-trust law) demands a common axiological framework. In this context, ne bis in idem must be understood as a defence right based on equity and proportionality. As far as its international dimension is concerned, ne bis in idem also lacks an erga omnes effect and it is not considered to be a rule of ius cogens. Consequently, the model which the ECJ has built regarding the application of the ne bis in idem in transnational and supranational contexts should be replicated by other courts through cross fertilization, in order to internationalize that procedural guarantee and broaden its scope of application.

The purpose of the following study is to analyze the relevance of the principle of confidentiality concerning mediation on civil and commercial matters developed in Portugal. We will, essentially, try to determine just how pivotal is this principle and how it affects the effectiveness of that method of alternative dispute resolution. We believe it is fundamental to understand the true extent of this principle and its goals, emphasizing the protection given to those who decide to resort to mediation and its impact on this process. For this dissertation, we have based our analysis on the interpretation of the set rules assembled by Law nr 29/2013, April 19th, while combining it with data gathered from other laws and regulations that had also addressed mediation. Furthermore, given the fact that this subject has been regulated by Directive 2008/52/EC, we deem pertinent to include references to other European mediation regulations, namely from Germany, Spain and France. With this study, we have established that, even though the Portuguese mediation law is based on a European Directive, we have determined a more restrictive regulation for the principle of confidentiality. We have concluded that the rules regarding this principle try to preserve, above all, the trust and honesty established during the course of the mediation, while restricting the possibility of using the information disclosed during these sessions on other cases. Additionally, we believe confidentiality is such a distinctive and relevant feature that its legal framework leads us to deem it as a true obstacle to the parties’ private autonomy and their power to determine how the mediation should be carried out.

This dissertation analyzes how the current Constitution and the Brazilian law establish consumer protection, arbitration and access to justice. Following we try to demonstrate why arbitration is a method rarely used in the resolution of consumer disputes in Brazil. It also examines the doctrinal and jurisprudential aspects of the conflict between the Brazilian Arbitration Law (Law nº. 9.307/96), which allows the arbitration clause in contracts of adhesion, and the Consumer Protection Code (Law nº 8.078/90) that in article 51, VII, considers as abusive the arbitration clause. Furthermore, analyzes new proposed bills under scrutiny by the National Congress on the issue and identifies the causes, in the Brazilian legal system, hampering the use of arbitration in consumer relations. Concludes that there are no principle obstacles preventing consumer litigations to be settled by arbitration. High costs, mistrust, oppression, misinformation of consumers and non-participation of the State, being a totally private institute, are factors that generate distrust, suspicion, and have prevented the development of arbitration in consumer relations in Brazil.
