As hepatites virais constituem um dos mais importantes assuntos de saúde pública, podendo ser causadas por diferentes agentes etiológicos. Dentre estes, encontra-se o vírus da hepatite C (VHC), que segundo a Organização Mundial da Saúde (OMS) afeta mundialmente cerca de 123 milhões de pessoas, com uma prevalência de 3%. A principal forma de transmissão do VHC é a exposição ao sangue contaminado. O VHC pertence à família Flaviviridae, gênero Hepacivirus, possui 6 genótipos e múltiplos subtipos. No Brasil, o genótipo 1 é observado em 70% dos pacientes infectados, seguido pelo genótipo 3 (25%) e o genótipo 2 (5%). Alguns fatores de risco são fortemente associados à transmissão do VHC, dentre eles: o uso de seringa de vidro esterilizada em domicílio; o compartilhamento de utensílios de higiene pessoal como a lâmina de barbear, escova de dente, alicates de manicure e cortadores de unhas e também a transfusão de sangue antes de 1993. A proposta do presente estudo foi investigar a frequência de auto-anticorpos em indivíduos brasileiros portadores de hepatite C crônica. Foram incluídos 14 indivíduos com diagnóstico clínico e laboratorial de VHC crônica e 45 indivíduos foram incluídos como controle. Foi realizada a pesquisa de auto-anticorpos tireoidianos por Imunoensaio Quimioluminescente de Micropartículas (CMIA). Em relação ao anti-TPO, os portadores do vírus da hepatite C foram negativos em 92,86% e no grupo controle foram encontrados 15,56% positivos e 84,44% negativos. Para antireoglobulina 92,86% dos portadores de HVC foram positivos e 88,37% no grupo controle. Neste estudo não foi encontrada diferença na frequência de desordens tireoidianas quando comparados os pacientes com Hepatite C sem tratamento específico com aqueles sem Hepatite C, justificado provavelmente, pela alta prevalência de DAT na população do grupo controle. Os resultados indicam a necessidade de uma amostragem maior de indivíduos para que comprovação do papel do vírus C isoladamente como desencadeador de DAT.

Devido à alta mortalidade e, principalmente, a morbidade, as hepatites são um dos mais graves problemas de Saúde Pública, no País e no mundo. Entre elas destacamos a infecção da hepatite C. O número de pessoas que desconhecem que são portadoras do vírus HCV é relevante. Como atualmente a transmissão do HCV por transfusão sanguínea e hemoderivados é rara entre os doadores de sangue, depois da introdução do método de triagem nos centros hemoterápicos, fundamental para detectar a existência de uma possível infecção neste doador. A realidade epidemiológica da hepatite C em Imperatriz necessita de maior conhecimento e planejamento das estratégias de prevenção e assistência aos portadores de HCV, uma vez que não existe uma rede de serviço consolidada para o tratamento, a burocracia é grande para se chegar ao diagnóstico da doença e a sub-notificação dos casos é elevada. Tem como objetivo avaliar a soroprevalência do HCV em candidatos à doação de sangue no município de Imperatriz – MA; assim como analisar o perfil dos candidatos considerados inaptos a doação de sangue no HEMOMAR, nesta cidade; determinar a soroprevalência do Vírus da Hepatite C entre os doadores de sangue no período de 2005 a 2010; realizar o levantamento dos dados epidemiológicos, destacando o gênero e a faixa etária de maior prevalência do vírus da hepatite C; comparar os dados epidemiológicos identificando a procedência dos candidatos soropositivos para o vírus da hepatite C. o estudo é de caráter descritivo transversal, envolvendo doadores de sangue do Centro de Hematologia e Hemoterapia do Estado do Maranhão de Imperatriz - MA. Na distribuição dos doadores de sangue do HEMOMAR, regional de Imperatriz -MA quanto ao sexo, constata-se que, nos anos de 2005 à 2011 o fluxo de doadores caracterizou-se por indivíduos de ambos os sexos,com predominância do masculino (75,01%), quando analisamos o perfil dos candidatos a doadores com sorologia positiva para HCV, observamos que estes também eram a maioria. A faixa etária dos doadores de sangue do HEMOMAR predominante era de 18-29. Os candidatos a doação com sorologia positiva para HCV, foram encontrados 79,17% na situação de casados/união estável. Entre os doadores que foram considerados inaptos a doação, 0,21% apresentou sorologia positiva para HCV. A maioria dos candidatos a doadores com soropositividade para HCV pertencia ao município de Imperatriz. Concluiu-se que é importante lembrar que o processo de triagem clínica e laboratorial diminui riscos de contaminação no processo de transfusão sanguínea. A figura do doador de sangue deve ser sempre valorizada e parabenizada por todos.

In this paper, we analyze the theoretical work of Renaud Barbaras, departing from his proposal to highlight and develop the potential of Husserl's theory of perception, based on the doctrine of perceptive donation according to profiles. We mainly focused on his work entitled Desire and distance: introduction to a phenomenology of perception. We underline the description, operated by the author, about the vital movement as desire and the characterization of the subject of the perception as living. In this condition, the formulation about the priority of a dimension emerges, qualified by Barbaras as pulsion towards the objectifying dimension of classical epistemology in the subject-object relation. We indicate that, according to the author, these rearrangements entail the need to consider the body, perception and movement based on the category of life.

In the last twenty years, and more expressively in the past decade, the search for improvement in the organ transplantation system has contributed to the achievement of positive results in the Brazilian statistics related to the survival of transplanted individuals. However, for a transplantation to be performed, a number of phases must be followed by professionals working in organ search services. The phase that generates the greatest tension is undoubtedly that of family interviews, as it involves both the feelings of relatives who are facing a recent loss and those of interviewers who need to know how to deal with families at this time. The goal of this study was to apprehend perceptions of professionals working for an Organ Search Organization concerning interviews with relatives of potential donors. The qualitative methodology was used by adopting the Collective Subject Discourse for data organization. Interviews were conducted with six staff members of an organ search service whose experience as interviewers comprised from eight to fourteen years of work. It was possible to apprehend the professionals’ perceptions of family interviews and identify facilitating and hindering factors in this phase of the donation process. Such factors mainly involve: contact with the teams assisting patients, the difficult moment that families are experiencing and the teams’ as well as the institution’s preparation for rendering this type of service. The balance between the offer of and demand for organs in Brazil will only be achieved by means of an efficient and effective structure in transplantation organ search services and increased donation consent rates to be obtained by adequate communication between interviewers and relatives

Atherosclerosis is a chronic inflammatory disease characterized by accumulation of lipid and fibrous components in arterial vessels, giving rise to atheromas. Development of Atheromatou plaques leads to arterial steatosis, triggering ischemic events. Atherotrombosis has a strong correlation with atherosclerosis, where rupture of atheromatous plaques cause release of vessel wall's pro-thrombotic components, activating platelet aggregation and thromosis. Due to the major role played by platelets on thrombus-embolic conditions, drugs that inhibit platelet aggregation demonstrate great relevance for atherothrombosis prevention, reducing patient mortality. Currently, there are a variety of drugs acting on several different targets, preventing platelet activation. However, these therapies demosntrate side effects such as thrombocytopenia, neutropenia, hemorrhage and low oral availability. Thus, the application of molecular modifications such as hybridization can produce novel, more efficient antiplatelet aggregation inhibitors. In this project we describe the synthesis and characterization of novel N-acilhydrazone compounds, acting through multiple mechanisms such as platelet calcium chelation and nitric oxide donation by furoxanic subunits. Furthermore, we demonstrate that such compounds exhibit biological activity in in vivo bleeding time, in vitro antiplatelet aggregation and in vivo antinociceptive assays. Therefore, novel N-acilhydrazone compounds demonstrate potential as antiplatelet drugs for atherothrombosis prevention.

Accidents caused by thermal, chemical, electrical or radioactive agents cause skin lesions causing burns of varying degrees. The therapeutic approach aims to restore damaged tissues and involves a wide range of products on the market. This study aims to evaluate the use of biological dressing, biotech product developed at the Blood Center of Botucatu / UNESP obtained from fresh frozen plasma or platelet concentrate with in vitro addition of thrombin and calcium gluconate. This addition in the platelet concentrate, intended to release the active growth factors of the platelets granules on the healing process. The study of the effectiveness of Platelet Gel home made in Wistar rats was established, in agreement with scald burns, comparing efficacy and cost of Platelet Gel with usual hospital -based treatment collagenase + chloramphenicol plus cost analysis through pharmacoeconomics. We used 25 Wistar rats were divided into 3 treatment groups: Group A, Collagenase + Chloramphenicol; Group B, Platelet Gel and C, control. The products were applied every other day for 30 days in animals. In group A, there was the presence of erythema and crust in all animals. The exudates was indentified 2/10 animals. For the Group B, we observed the presence of erythema and crust at all and no presence of exudates. In group C all the animals showed erythema with no presence of exudates and scab occurred in 1/10. Statistical analysis showed significant difference ( p < 0.0 ) for crust formation between Groups B and C. In the histological analysis, group A showed a slight amount of blood vessels and collagen fibers, moderate amounts of macrophages and fibroblasts was observed while B and C groups showed moderate amounts of blood vessels, macrophages and fibroblasts and discreet presence of collagen fibers. The re-epithelialization occurred in most animals of all groups without significant statistical differences. For the aspects of pharmacoeconomics, the platelet gel presented a better cost - effectiveness in relation to treatment based on collagenase / chloramphenicol. In light of the ethical aspects of the raw material is the result of spontaneous blood donation, the proposal should have biological dressings productions the responsibility of public blood transfusion centers for free distribution. This may point to the production chain of Brazilian blood banks like special blood components for use no intravenous.

Purpose: Study aiming to understand the reasons for the refusal to donate organs by relatives of potential donors living in the Mid-Western region of the São Paulo state. Method: Qualitative study performed after data collection by the Organ Procurement Organization (OPO) Division of a reference hospital in the region. Relatives were contacted to participate in a semi-structured interview, and after the subjects in the study were characterized, four guiding questions were presented; their respective answers were recorded to be transcribed later. The Analysis of Content method proposed by Bardin was used to organize the speeches. Results: From 2006 to 2008, 30 (35.3%) families contacted by OPO have refused to agree with the organ donation. From that universe, 16 family members were interviewed. Data was systematized in three major themes: The experience of being informed on a family member’s brain death, decision concerning to the organ donation and aspects that would facilitate the decision to agree with the organ donation. Conclusion: the identification of reasons for the refusal and the suggestions presented has provided subsidies to improve the organ donation for transplantation process.
