Pathogenesis of HIV-1 nef in adult mice

Rahim, Mir Munir Ahmed, 1975- January 2008 (has links)
Development of a suitable animal model of AIDS is much needed in AIDS research to study infection and pathogenesis as well as to evaluate methods of prevention and treatment of HIV infection. Small animals such as rodents are attractive candidates for AIDS research due to the availability of various inbred and genetically engineered strains, extensive knowledge or their immune system, especially in mice, and the relative ease of breeding and maintaining animal colonies. Transgenic small animal models carrying entire HIV genome or selected genes have been instrumental to understand functions of HIV genes in vivo and their role in HIV pathogenesis. The type of cells in which HIV genes are expressed seems to be an import prerequisite for the study of HIV gene functions in transgenic mice. Mice constitutively expressing the entire HIV-1 genome or HIV-1 nef gene in CD4 + T cells and in the cells of macrophage/dendritic lineage develop an AIDS-like disease very similar to AIDS disease in humans. Similarly, expression of Nef in adult mice, using inducible system, results in the AIDS-like disease. This disease is characterized by thymic atrophy, impaired thymocyte maturation, loss of CD4+ T cells, increased activation and turnover of T cells, which can occur in the absence of lymphypenia, and non-lymphoid organ disease involving the lungs and kidneys. Susceptibility of adult mice to the pathological effects of Nef suggests that the AIDS-like disease in the constitutively expressing Nef Tg mice is not due to developmental defects caused by early expression of Nef. This model highlights the important role of Nef in HIV-1 pathogenesis. The high similarity in the disease in these Tg mice with human AIDS strongly suggest that these mice are a relevant model to study AIDS. This study further evidence that mouse cells can support functions of Nef and these Tg mice represent a unique model to study Nef functions in vivo in the context of the primary immune system. Moreover, the inducible Nef Tg model has given us the ability to control the level and time of expression of Nef which was impossible to do in the previously reported constitutive Nef Tg mouse models. These mice will be useful to study immune reconstitution since Nef expression can be turned off after withdrawal from dox.

PERSPECTIVA DE REDE DE ATENÇÃO À SAÚDE DE CRIANÇAS E ADOLESCENTES VIVENDO COM HIV / PERSPECTIVE OF NETWORK ATTENTION TO HEALTH OF CHILDREN AND ADOLESCENTS LIVING WITH HIV

Kinalski, Daniela Dal Forno 15 February 2016 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Children living with Human Immunodeficiency Virus (HIV) or Acquired Immune Deficiency Syndrome (AIDS) require health-monitoring demands beyond the usual, due to the specifics of their HIV status. Among the demands, there is the ongoing control of health and dependence on drug technology. However, the fragility to access services of Primary Health Care (PHC) results in an engagement with specialized services. It is recommended that specialized services benefit themselves from the APS services, towards the quality of health care, preferably coordinated by APS. In this sense is that the realization of a Network Health Care (NHC) want integration between services, consistent with the public policy of national health. Thus, it is necessary to structure the municipal policy to implement a transfer system, defining the responsibility activities of each service and continuing education of professionals who need to know the children and adolescents living with HIV in their area, and develop actions of commitment and strengthen bonds. In this sense, this research has the aim of discussing with the professionals the NHC of children and adolescents living with HIV, perspectives care line and flow in the city of Santa Maria, Rio Grande do Sul, Brazil. Methodology: qualitative approach conducted through the technique of focus groups with 23 health professionals, PHC and specialized service, totaling four sessions. The study setting was the PHC services of Santa Maria, the University Hospital of Santa Maria and Casa Treze de Maio. Content Analysis and respected the ethical aspects of research involving human beings, according to the Resolution 466/12 of the National Health Council were developed. Results: The health care of children and adolescents living with HIV in Santa Maria is performed in specialized services . This is due to conceptual, structural and social aspects. To this end, in an attempt to decentralize this health care model in specialties, it was discussed and rearranged this attention to health through the construction of a line of care for this population. The conceptions of each point of attention have been defined, the articulations and the necessary operationalizations for better integration between the health care points. It is noteworthy that this dissertation was a product: the flow of health care for children and adolescents living with HIV in Santa Maria. Final thoughts: the discussions provided the reorganization of a care model that was fragmented, focusing on the clinical management of the disease to a model of attention to health shared between points based on the principles of RAS. / As crianças vivendo com o Vírus da Imunodeficiência Humana (HIV) ou com a Síndrome da Imunodeficiência Adquirida (aids) exigem demandas de acompanhamento em saúde além do habitual devido às especificidades de sua condição sorológica. Dentre as demandas, destacam-se o acompanhamento permanente de saúde e a dependência de tecnologia medicamentosa. No entanto, a deficiência de acesso aos serviços de Atenção Primária à Saúde (APS) resulta na afiliação aos serviços especializados. Recomenda-se que esses serviços especializados contem com os serviços de APS, visando a qualidade da atenção à saúde, preferencialmente sob coordenação da APS. Neste sentido, a efetivação de uma Rede de Atenção à Saúde (RAS) pretende a integração entre os serviços coerente com a política pública de saúde nacional. Para tanto, faz-se necessária à estruturação da política municipal para implementação de um sistema de transferência, definição das atividades de responsabilidade de cada serviço e da educação permanente dos profissionais. Estes precisam conhecer as crianças e os adolescentes vivendo com HIV na sua área de abrangência e desenvolver ações de acolhimento e fortalecimento de vínculos. Assim tem-se como objetivo discutir com profisisonais da Rede de Atenção à Saúde de crianças e adolescentes vivendo com HIV, perspctivas de linha de cuidado e fluxo de atenção no município de Santa Maria, Rio Grande do Sul, Brasil. Metodologia: Abordagem qualitativa realizada por meio da técnica de grupo focal com 23 profissionais de saúde da APS e do serviço especializado, totalizando quatro sessões. O cenário de estudo foi composto pelos serviços de APS de Santa Maria, o Hospital Universitário de Santa Maria e a Casa Treze de Maio. Foi desenvolvida a Análise de Conteúdo e respeitados os aspectos éticos das pesquisas com seres humanos, seguindo a Resolução 466/12 do Conselho Nacional de Saúde. Resultados: A atenção à saúde das crianças e adolescentes vivendo com HIV em Santa Maria é realizada nos serviços especializados. Isso é decorrente de aspectos conceituais, estruturais e sociais. Para tanto, na tentativa de descentralizar esse modelo de atenção à saúde em especialidades, foi discutida e reorganizada essa atenção à saúde por meio da construção de uma linha de cuidado para essa população. Foram definidas as concepções de cada ponto, as articulações e as operacionalizações necessárias para uma melhor integração entre os pontos de atenção à saúde. Destaca-se que o presente estudo teve um produto: o fluxo de atenção à saúde das crianças e adolescentes vivendo com HIV em Santa Maria. Considerações finais: As discussões proporcionaram a reorganização de um modelo de atenção que era fragmentado, com foco no controle clínico da doença para um modelo de atenção à saúde compartilhado entre os pontos, utilizando como base os princípios da RAS.

The objective was to assess the quality of Primary Health Care (PHC) of municipalities origin of children and adolescents living with HIV linked to a specialized service. It is a cross-sectional survey, developed in the PHC service of 25 children home municipalities and adolescents living with Human Immunodeficiency Virus (HIV) that are continuously monitored in the outpatient pediatric infectious diseases at the University Hospital of Santa Maria (HUSM). Data collection took place through the application of PCATool-Brazil Professional version instrument, from March to August 2014. The analysis was carried out with SAS software version 9.3. The population totaled in 527 professional doctors, nurses and dentists. In the assessment of the essential attributes of the PHC, the longitudinality, coordination of information systems, integral services and integrity services indicated that the Family Health Strategy (FHS) has a high score for PHC when compared to Basic Health Unit (BHU).The first contact of access resulted in low scores. The FHS and BHU were compared resulting in items treatment on the same day and ease medical consultation marking were statistically associated with high scores. Strategies that qualify the PHC include: investment in the expansion of the FHS service coverage; investment in training of professionals for the care of chronic diseases such as HIV. Besides the need for coordination between the PHC services, specialized services and other health care network services, increasing access of children and adolescents living with HIV, and the ongoing and resolute attention. / Objetivou-se avaliar a qualidade da Atenção Primária à Saúde (APS) dos municípios de procedência de crianças e adolescentes vivendo com HIV vinculados a um serviço especializado. Trata de uma pesquisa transversal, desenvolvida nos serviços de APS de 25 municípios de origem de crianças e adolescentes vivendo com Vírus da Imunodeficiência Humana (HIV) que fazem acompanhamento permanente no serviço ambulatorial de infectologia pediátrica do Hospital Universitário de Santa Maria (HUSM). A coleta de dados realizou-se por meio da aplicação do instrumento PCATool-Brasil versão profissionais, entre março a agosto de 2014. Foi realizada a análise com Software SAS versão 9.3. A população totalizou em 527 profissionais médicos, enfermeiros e odontólogos. Na avaliação dos atributos essenciais da APS, a longitudinalidade, coordenação sistemas de informação, integralidade serviços disponíveis e integralidade serviços prestados indicaram que a Estratégia de Saúde da Família (ESF) apresenta alto escore para APS quando comparada a Unidade Básica de Saúde (UBS). O acesso de primeiro contato resultou em baixo escore. Quando comparadas ESF e UBS, os itens atendimento no mesmo dia e facilidade de marcação de consulta foram estatisticamente associados ao alto escore. Estratégias que qualificam a APS incluem: investimento na expansão da cobertura do serviço da ESF; investimento na capacitação dos profissionais para o atendimento de doenças crônicas como o HIV. Além da necessidade de articulação entre os serviços da APS, serviços especializados e demais serviços da rede de atenção à saúde, potencializando o acesso das crianças e adolescentes vivendo com HIV, bem como a atenção contínua e resolutiva.
