O referencial te?rico utilizado baseia-se em Michel Foucault e em Giorgio Agamben, principalmente nos conceitos de governo e de vida nua, respectivamente. Analisam-se os efeitos das pr?ticas desses referidos saberes dirigidos a essa popula??o, bem como se conclui que o modo de governar essa juventude reside em pr?ticas tanatopol?ticas; ou seja, trata-se mais de um governo sobre a morte do que sobre a vida desses adolescentes.

O consumo de drogas e álcool constitui cada vez mais um problema social e de saúde pública, pelas consequências negativas que provocam no desenvolvimento emocional e físico dos indivíduos. Existem poucas referências na literatura avaliando o uso destas substâncias por portadores de doença falciforme (DF). Estes pacientes apresentam crises álgicas severas, recorrentes, frequentemente controladas por opióides. O comprometimento da qualidade de vida predispõe a ocorrência de transtornos psiquiátricos não-psicóticos, como depressão por exemplo, tornando o grupo vulnerável ao uso abusivo de substâncias. Objetivos: avaliar o consumo de álcool e drogas em pacientes portadores de DF acompanhados pelo Centro de Referência de Doença Falciforme (CRAF) do Hospital de Clínicas de Porto Alegre (HCPA), estimar o percentual de pacientes em tratamento da doença falciforme que fazem uso abusivo de álcool e drogas, e colaborar com o estudo que avaliará a efetividade de um centro de referência multidisciplinar para esta população. Métodos: estudo transversal, de uma amostra de conveniência, com 139 pacientes portadores de DF acompanhados no CRAF do HCPA. Resultados: a prevalência do uso abusivo foi de 1,5% para o álcool e 3,0% para o tabaco, e não se identificou o uso abusivo de outras substâncias, inclusive opióides. O padrão para o uso de substâncias não foi influenciado pela exposição ou por transtornos psiquiátricos não-psicóticos. Conclusão: São necessários mais estudos para reforçar estes achados, mas demonstra-se a segurança do uso de analgésicos opióides para o manejo das crises dolorosas apresentadas pelos portadores de DF. / Drug abuse is increasingly becoming a social and public health problem, because of the negative consequences that such abuse causes on the emotional and physical development of individuals. There are few references in the literature evaluating the use of these substances by individuals with sickle cell disease (SCD). These patients have severe and recurrent pain crises, frequently needing opioids drugs to control it. The compromised quality of life can predispose this population to the occurrence of non-psychotic psychiatric disorders such as depression, making them vulnerable to substance abuse. Objectives: To evaluate the level of consumption of alcohol and drugs in patients with SCD followed by Sickle Cell Disease Reference Center (CRAF) at Hospital de Clínicas de Porto Alegre; to estimate the percentage of patients in treatment of SCD who abuse alcohol and drugs, and to collaborate with the study evaluating the effectiveness of the CRAF. Methods: cross-sectional study of a convenience sample of 139 patients with SCD treated at CRAF. Results: the prevalence of abusive use of the studied population was 1.5% for alcohol and 3.0% for tobacco, and no abusive use of any other substance, including opioids, was identified. It was verified that the pattern for substance use was not influenced by exposure to substances or the presence of non-psychotic psychiatric disorders. Conclusion: More studies are needed to reinforce these findings, but they suggested that the use of opioid analgesics for the management of SCD painful crises is safe and do not induces substance abuse.

Le coeur et les vaisseaux sanguins sont directement issus de l'endothélium et dépendent de sa fonction. Le coeur ne représente pas la seule force motrice de notre système circulatoire, la plupart des stratégies thérapeutiques actuelles des maladies cardiovasculaires sont encore focalisées sur le coeur, négligeant l'ensemble du système circulatoire et le système endothélial. Par exemple, le développement de Dispositifs d'Assistance Cardiaque (DAC) est influencé par le coeur, conçu pour suivre,obéir et doit être synchronisé avec un organe malade.De nombreux « signaux » de nature différente sont capables d’activer les cellules endothéliales : les forces de cisaillement créées par le flux sanguin parallèle à la surface de la paroi des vaisseaux, mais également les forces perpendiculaires provoquées par l’étirement de la paroi artérielle par les variations de la pression et la qualité cyclique de ces forces. L’activation de cellules endothéliales est due à la pulsatilité du flux mais aussi à l’action de substances vasoactives et des médiateurs de l’inflammation.Dans notre travail de thèse, nous proposons une nouvelle approche thérapeutique,basée sur une révision fondamentale de l'ensemble du système circulatoire: exposer les défauts de la gestion courante des maladies cardiovasculaires (MCV). Notre nouveau concept se concentre sur la dynamique des flux sanguins pour stimuler,restaurer et maintenir la fonction endothéliale, et compris le coeur lui-même. Nous avons développé et évalué une nouvelle génération de DAC pulsatiles, testée in vitro et in vivo.Pendant le déroulement de cette thèse nous avons effectué les études suivantes:1. Etude d’un prototype de cathéter pulsatile. Il est testé de manière isolée dans un modèle expérimental d’ischémie aiguë du myocarde et dans un modèle d’hypertension pulmonaire aiguë.2. Etude d’un prototype de tube pulsatile à double lumière. Il est testé in-vitro dans un circuit de circulation extracorporelle, et in vivo comme assistance ventriculaire gauche.73. Etude d’un prototype de combinaison pulsatile. Il est testé sur un modèle animal présentant une défaillance aiguë du ventricule droit. Des prototypes de masques et de pantalons pulsatiles sont en développement.En conclusion, notre approche est basée sur l’activation de la fonction endothéliale plutôt qu’en une assistance cardiaque directe. Ce concept permet une meilleure gestion thérapeutique des maladies circulatoires et cardio-pulmonaires. / The “Heart” is still considered as the main organ to be dealt with, in case ofcardiovascular disease. Nevertheless, the heart is not the only driving force in ourcirculatory system. In fact, the heart and blood vessels are the direct issues of theendothelium and depend on its function. Moreover, almost all current therapeuticstrategies are still focusing on the heart and neglecting the entire circulatoryendothelialsystem. For example, development of cardiac assist devices (CAD) is stillrestrained by the heart, designed to follow, obey and must be synchronized with adiseased organ.Many "signals" of different nature are capable of activating endothelial cells: the shearforces created by the blood flow parallel to the surface of the vessel wall, but alsoforces caused by stretching perpendicular to the artery wall by the cyclic pressuregradient and the quality of these forces. The activation of endothelial cells is due tothat pressurized flow dynamic forces, but also to the action of vasoactive substancesand inflammatory mediators.In this thesis we are proposing a new therapeutic approach, based on a fundamentalrevision of the entire systems: exposing those defects of current management ofcardiovascular diseases (CVD). A concept that focuses on flow dynamics to stimulate,restore and maintain endothelial function including the heart itself. This includespreliminary results of new generations of pulsatile CAD that promote endothelial shearstress (ESS) enhancement. Devices prototypes were tested.During this thesis, pulsatile devices prototypes were tested in vivo, in vitro as well aswith pre-clinical volunteers as follow:1. A pulsatile catheter prototype was tested in 2 pediatric animal models (piglets) of:acute myocardial ischemia; and acute pulmonary arterial hypertension.2. A pulstile tube prototype was tested in vitro (mock circuit) and in vivo (piglets) as aleft ventricular assist device (ongoing).3. Pulsatile suit prototypes were tested: in vivo (piglets) for acute right ventricularfailure treatment. Prototypes of pulsatile mask and trousers are currently in plannedfor pre-clinical studies.9Conclusion, Think endothelial instead of cardiac is our policy for better management ofCVD.

I seek to understand the experience of chronic disease from some fundamental changes in people's lives after the advent of the disease and how the experience of illness is related to the social position of the individuals, in their circle of interpersonal relationships and, more broadly, social structures, highlighting the categories of gender and class. Moreover, I highlight some assimilation processes and coping with the disease in the daily life of people in the condition of chronic disease, as well as some reconfigurations and rearrangements of the identity of the sick person from the appropriation of this new condition. / O presente trabalho busca refletir sobre o fen?meno sa?de-doen?a na experi?ncia de portadores de doen?as reum?ticas cr?nicas, para tanto duas pesquisas de car?ter qualitativo etnogr?fico foram realizadas.

With the creation of CREAS occurred the reorganization of specialized services and programs which were scattered within the socialassitantial network and began to be part of this center, creating a mosaic of actions directed to people with their rights violated. At the same time, there was a significant arrival of psychologists to the field of Social Assistance and their questioning facing specialized social demands and the (un)definitions of SUAS‟ policy concerning to special social protection. Was aimed in this research to investigate how psychologist‟s practices are developed at CREAS using semi-structured interviews and following the practices developed by three psychologists at a CREAS in the state of Rio Grande do Norte (RN), indicated by the Ministry of Social Development and Fight against Hunger (MDS) as one of the national references in 2008. It was highlighted a complex work field, which is delineated between the user?s rights perspective and the maintenance of historical difficulties concerning to the Social Assistance. In which the professional is requested to act toward the fight against rights violation, but does not find a field where is possible inter-sector and articulated work, in addition of being exposed to the precariousness of work and the weakness of employment ties, associated to the lack of formation to work in the area. Accordingly, there is still a range of challenges to psychologists in the building of a profession which confront risk situations and break off rights violation. / O objetivo desta pesquisa foi investigar a atua??o do psic?logo no Centro de Refer?ncia Especializado de Assist?ncia Social (CREAS), unidade da prote??o social especial de m?dia complexidade do Sistema ?nico de Assist?ncia Social (SUAS).

Concomitantemente, h? a entrada significativa de psic?logos no campo da Assist?ncia Social e os questionamentos desses profissionais frente ?s demandas sociais especializadas e ?s (in)defini??es da pol?tica do SUAS quanto ? prote??o social especial. Buscou-se nesta pesquisa investigar como a atua??o do psic?logo ocorre no CREAS por meio de entrevista semi-estruturada e de acompanhamento das pr?ticas desenvolvidas por tr?s psic?logas em um CREAS no Rio Grande do Norte (RN), apontado como uma das refer?ncias nacionais pelo Minist?rio do Desenvolvimento Social e Combate ? Fome (MDS) em 2008. Evidenciou-se um campo complexo de atua??o, que se delineia entre a perspectiva do direito do usu?rio e a manuten??o de dificuldades hist?ricas pertinentes a Assist?ncia Social. Em que o profissional ? solicitado a agir para enfrentamento da viola??o do direito, mas n?o encontra um campo que possibilite o trabalho intersetorial e articulado, al?m de estar exposto a precariza??o do trabalho e a fragilidade dos v?nculos empregat?cios, associado ? falta de forma??o para atuar na ?rea.

The activities to be developed by psychologists in these services are greatly important for the elaboration and development of political- pedagogical project of the same, and for reasons pertaining to the present and future of children and adolescents received judgments. The psychologist puts up the challenge of contributing to a better care of children, also cooperating with the implementation of the new care standards of childcare. The aim of this study was to investigate the role of the professional psychologist in assistance to children and adolescents in 13 Shelters in the Metropolitan Region of Natal/RN. For both set out to make visits to the institutions to know how it is organized the field work of the psychologist, his routine work and activities developed. Nine psychologists interviewed according to a semi-structured interview script. The data analysis is supported by the theoretical aspects of dialectical materialism historical and theme content analysis was used. Results were presented from three angles: psychologists and institutional framework; activities, resources and methods of work; psychologists and legal frameworks of the Institutional Hospitality. The study points out the recent entry of the psychologist in Shelters, combined with considerable turnover of these professionals. This work has been organized through the Individualized Service Plan, prioritizing the return to family of origin. Moreover, in general, perform joints with the service network, reporting, individual consultations and follow-adoption processes . Staff members, however, feel a lack of specific and continuing training on special protection, including due to the distance between the proposed theory and practice. It was thus observed a movement of psychologists distance themselves from welfare or repressive practices, however the structural difficulties of services and lack of continuing education appear to limit the development of a performance focused on the transformation of the reality of children and adolescents treated and their families / Os Servi?os de Acolhimento s?o respons?veis por cuidar das crian?as e adolescentes cujas fam?lias ou respons?veis est?o temporariamente impossibilitados de cumprir sua fun??o de cuidado e prote??o.

The number of patients that are waiting for heart transplants far exceed the number of available donor hearts. Left Ventricular Assist Devices are mechanical alternatives that can help and are helping several patients. They work by taking blood from the left ventricle and ejecting that blood into the aorta. In the University of Louisville they are developing a similar device that will take the blood from the aorta instead of the ventricle. This new device is called an Artificial Vasculature Device. In this thesis the arterial system and AVD are modeled and a simple control algorithm for the AVD proposed. The arteries are modeled as a tube with linear resistance and inertia followed by a chamber with linear compliance and last a tube with linear resistance. The model is identical to the 4-element Windkessel model. The values for the resistances, inertia and compliance are identified using pressure and flow measurements from the ventricle and aortic root from a healthy patient. In addition to the Windkessel model the aortic valve is also modeled. The valve is modeled as a drum that closes the aorta and the parameters identified like before. The measurements are also used to model the left ventricle by assuming it has a constant compliance profile. The AVD is modeled using common modeling structures for servo motors and simple structures for tubes and pistons. The values for the AVD could not be measured and identified so they are fetched from preliminary motor and part specifications. The control algorithm for the AVD uses a wanted load to create a reference aortic flow. This wanted aortic flow is then achieved by using a PI controller. With these models and controller the interaction between the arterial system and AVD is investigated. With this preliminary understanding of the interaction further research can be made in the future to improve the understanding and improve the AVD itself.
