Levantamento de condições de saúde de alunos dos estabelecimentos de ensino primário da Secretaria dos Negócios da Educação do Governo do Estado, no município de São Paulo Brasil

Fez-se um levantamento das condições de saúde de escolares primários do município de São Paulo. Nos alunos componentes da amostra foram realizados os seguintes exames: exame físico geral; exame físico especial; exame de fezes. Os resultados obtidos no exame físico geral permitiram construir tabelas de peso e altura para crianças de ambos os sexos, de 7 a 14 anos. Foi verificada a presença de parasitoses intestinais em 89,4% dos escolares examinados. Concluiu-se que, ao nível de significância de 1%, existe associação entre ausência de saneamento básico nas residências dos escolares e a presença de parasitos intestinais nos exames de fezes.

Cost of diseases in Brazil: breast cancer, enteritis, cardiac valve disease and bronchopneumonia

The results from the need to develop methodologies for performing cost analysis in developing countries, principally in the region of Latin America, were studied. It, furthermore, serves to generate knowledge from an economic evaluation in order to support decision-making related to the organization of health systems, particularly in the efficient use of resources which are allocated for the provision of medical services. Two chronic diseases (breast cancer and cardiac valve disease) and two infections (enteritis and bronchopneumonia) were selected for the study. The results recommend the use of a valid methodology for economic cost analysis of any disease to be studied and the use of this information in the decision-making process.

Costos de intervenciones para pacientes con insuficiencia renal crónica

INTRODUCCIÓN: Se presentan resultados sobre un estudio que pretendió identificar los costos de intervenciones en salud en el manejo de pacientes con insuficiencia renal crónica. MATERIAL Y MÉTODO: El método de costeo se basó en técnicas de consenso y de instrumentación de manejo de caso a través de la identificación de insumos y funciones de producción para la demanda de cada servicio solicitado. Las intervenciones costeadas incluyeron: diálisis peritoneal, hemodiálisis y trasplante renal. RESULTADOS: El costo por evento en US dóllares fué de $3.71, $57.95 y $ 8,778.32 respectivamente. En cuanto al costo de manejo anual de caso los resultados fueron: diálisis peritoneal $5,643.07, hemodiálisis $9,631.60 y trasplante $3,021.67. CONCLUSIONES: La información generada a partir de los costos de eventos difiere considerablemente de la información generada a partir del costo de manejo anual de caso. Estas diferencias resultan significativas para el diseño y evaluación de patrones de asignación de recursos

Costo-efectividad de intervenciones para insuficiencia renal crónica terminal

OBJETIVO: Analisó el costo-efectividad en intervenciones para pacientes con insuficiencia renal crónica terminal (IRCT) en términos de los costos económicos de cada intervención, los años de vida ganados y la calidad de vida que generan tres alternativas comparables y mutuamente excluyentes: diálisis peritoneal contínua ambulatoria (DPCA), la hemodiálisis (HD) y el trasplante renal (TR). MÉTODO: El diseño del estudio fue de tipo longitudinal. Los costos de cada intervención se determinaron mediante la técnica de manejo de caso promedio. Las medidas para evaluar los criterios de efectividad elegidos fueron la probabilidad de sobrevida y el Año de Vida Ajustado por Calidad (QALY, Quality Adjusted Life Year) medido por el Indice de Rosser. RSULTADOS: Los costos de manejo anual de caso fueron: diálisis peritoneal $5,643.07, hemodiálisis $9,631.60 y trasplante $3,021.63. En cuanto a la efectividad, la sobrevida del injerto de trasplante renal resultó de 89,9% y 79,6% a uno y tres años respectivamente, mientras que los pacientes sometidos a DPCA tienen una sobrevida de 86,2% y 66,9% a un año y a tres años respectivamente. En cuanto a los QALY's, los resultados para cada intervención fueron: DPCA 0,879; HD 0,864; y para el TR 0,978. CONCLUSIÓN: La intervención más costo-efectiva resultó el trasplante renal con un coeficiente de 3,088.69, seguido de la DPCA y la hemodiálisis, cuyos coeficientes fueron de 6,416.95 y 11,147.68 respectivamente. Por lo tanto se recomienda promover y utilizar el trasplante renal como la intervención más costo-efectiva para pacientes con IRCT.

Health financing changes in the context of health care decentralization: the case of three Latin American countries

OBJECTIVE: The results of an evaluative longitudinal study, which identified the effects of health care decentralization on health financing in Mexico, Nicaragua and Peru are presented in this article. METHODS: The methodology had two main phases. In the first, secondary sources of data and documents were analyzed with the following variables: type of decentralization implemented, source of financing, funds for financing, providers, final use of resources, mechanisms for resource allocation. In the second phase, primary data were collected by a survey of key personnel in the health sector. RESULTS: Results of the comparative analysis are presented, showing the changes implemented in the three countries, as well as the strengths and weaknesses of each country in matters of financing and decentralization. CONCLUSIONS: The main financing changes implemented and quantitative trends with respect to the five financing indicators are presented as a methodological tool to implement corrections and adjustments in health financing.

Efectos de la descentralización en el financiamiento de la salud en México

OBJETIVO: Identificar las tendencias y los efectos de la descentralización en las políticas de financiamiento de la salud en México. MÉTODOS: La población de estudio incluyó cuatro estados seleccionados bajo criterios técnicos: diferente desarrollo socio-económico; implementación de la descentralización; base de datos sobre información económica; confiabilidad y validéz de las bases de datos; y apoyo de un equipo interdisciplinario de investigación. Las técnicas de recopilación de información se basaron en entrevistas a profundidad con personal clave y análisis de documentos y bases de datos sobre los presupuestos estatales en salud para el período 1990-2000. RESULTADOS: El modelo de análisis propuesto permitió identificar las tendencias y efectos de la descentralización sobre las principales fuentes de financiamiento en salud: Hogares, Gobiernos Federal, Estatal y Municipal. Hay evidencias de niveles de efectividad muy variada en cuanto a los cambios en las políticas de financiamiento, particularmente en lo que se refiere a las tendencias en los montos económicos por tipo de fuente de financiamiento. CONCLUSIONES: Hay estados donde los hogares, los municipios y el mismo gobierno estatal han hecho efectivo un incremento importante en el financiamiento de la salud, pero también hay Estados donde continúa la dependencia económica del nivel federal y donde Hogares, Municipios y Estados no están dispuestos ni capacitados para asumir responsabilidad económica en materia de salud.

Effects of health decentralization, financing and governance in Mexico

OBJECTIVE: To identify the effects of decentralization on health financing and governance policies in Mexico from the perspective of users and providers. METHODS: A cross-sectional study was carried out in four states that were selected according to geopolitical and administrative criteria. Four indicators were assessed: changes and effects on governance, financing sources and funds, the final destination of resources, and fund allocation mechanisms. Data collection was performed using in-depth interviews with health system key personnel and community leaders, consensus techniques and document analyses. The interviews were transcribed and analyzed by thematic segmentation. RESULTS: The results show different effectiveness levels for the four states regarding changes in financing policies and community participation. Effects on health financing after decentralization were identified in each state, including: greater participation of municipal and state governments in health expenditure, increased financial participation of households, greater community participation in low-income states, duality and confusion in the new mechanisms for coordination among the three government levels, absence of an accountability system, lack of human resources and technical skills to implement, monitor and evaluate changes in financing. CONCLUSIONS: In general, positive and negative effects of decentralization on health financing and governance were identified. The effects mentioned by health service providers and users were related to a diversification of financing sources, a greater margin for decisions around the use and final destination of financial resources and normative development for the use of resources. At the community level, direct financial contributions were mentioned, as well as in-kind contributions, particularly in the form of community work.

Economic burden of expected epidemiological changes in diseases related to tobacco, Mexico

OBJECTIVE: To determine health care costs and economic burden of epidemiological changes in diseases related to tobacco consumption. METHODS: A time-series analysis in Mexico (1994-2005) was carried out on seven health interventions: chronic obstructive pulmonary diseases, lung cancer with and without surgical intervention, asthma in smokers and non-smokers, full treatment course with nicotine gum, and full treatment course with nicotine patch. According with Box-Jenkins methodology, probabilistic models were developed to forecast the expected changes in the epidemiologic profile and the expected changes in health care services required for selected interventions. Health care costs were estimated following the instrumentation methods and validated with consensus technique. RESULTS: A comparison of the economic impact in 2006 vs. 2008 showed 20-90% increase in expected cases depending on the disease (p<0.05), and 25-93% increase in financial requirements (p<0.01). The study data suggest that changes in the demand for health services for patients with respiratory diseases related to tobacco consumption will continue showing an increasing trend. CONCLUSIONS: In economic terms, the growing number of cases expected during the study period indicates a process of internal competition and adds an element of intrinsic competition in the management of preventive and curative interventions. The study results support the assumption that if preventive programs remain unchanged, the increasing demands for curative health care may cause great financial and management challenges to the health care system of middle-income countries like Mexico.

Vulnerabilidade de gênero para a paternidade em homens adolescentes

OBJETIVO: Analisar as relações de gênero vivenciadas por adolescentes do sexo masculino e como elas contribuem para torná-los vulneráveis à gravidez na adolescência. MÉTODOS: Estudo qualitativo realizado em Campo Grande, Mato Grosso do Sul, em 2003. Participaram 13 adolescentes masculinos com menos de 20 anos, com um único filho de até 11 meses, cuja mãe estava na mesma faixa etária do pai. Realizaram-se entrevistas semi-estruturadas gravadas. Após transcrição, procedeu-se à análise temática de conteúdo. RESULTADOS: Identificaram-se estereótipos de gênero em que se destacavam papéis de líder, provedor e ativo sexualmente, bem como a rejeição a ser cuidador. Esses papéis apareceram consolidados principalmente na perspectiva dos entrevistados acerca do trabalho como marcador de sua condição de homem e provedor da família. A liderança dos adolescentes prevaleceu no relacionamento com a mãe de seu filho, notadamente na iniciativa das relações sexuais e no uso de contraceptivos. A gravidez foi considerada por eles como "por acaso" e inesperada, mas a paternidade foi vivenciada como uma prova final de sua condição de homens adultos. CONCLUSÕES: Verificou-se a condição de vulnerabilidade dos adolescentes para a paternidade em virtude da socialização de gênero nos moldes tradicionais. Isso foi evidenciado com a ausência dos papéis relativos ao cuidado consigo próprio e com os outros, com a incorporação precoce de papéis de dominação sexual masculina e de trabalhador e pai, ou seja, deixar de ser criança e alcançar a condição de homem.

Paternidade: responsabilidade social do homem no papel de provedor

OBJETIVO: Analisar os significados atribuídos à paternidade por homens que são pais. DELINEAMENTO DO ESTUDO: Estudo realizado em João Pessoa, PB, em 2003, desenvolvido sob abordagem qualitativa e enfoque teórico de gênero. Os participantes do estudo foram dez homens, cujos filhos eram atendidos no ambulatório de puericultura de um hospital escola. As informações analisadas foram obtidas por meio de entrevistas semi-estruturadas. Os depoimentos foram analisados pela técnica de análise crítica do discurso. ANÁLISE DOS DISCURSOS: Os sujeitos do estudo concebiam a paternidade como um novo encargo social, vinculando-a mais à provisão material da família do que ao espaço de envolvimento afetivo com o(a) filho(a). Entretanto, os participantes experimentavam um processo de transição no qual o pai tradicional convivia entre aqueles cuja dimensão afetiva da paternidade apresentava-se como eixo central de preocupação do ser pai. CONCLUSÕES: O significado e o exercício concreto da paternidade situaram-se num campo de responsabilidades que predominantemente reproduzem o pai tradicional mas também recriam o papel de pai, com inclusão da dimensão afetiva.

Vision antropologica de la descentralizacion del sistema de salud en Mexico

OBJETIVO: Analizar cambios organizacionales, políticos y económicos resultantes de la descentralización del sistema de salud en la población sin seguridad social en México. METODOS: Se visitaron tres estados del país seleccionados por el número de habitantes en condición de pobreza, el partido político en el poder y la etapa de implementación de la descentralización (la primera fue en 1984 y la segunda en 1997). Se realizaron entrevistas durante 2007 con informantes clave de los servicios de salud de los gobiernos estatales, personas que acudieron a consulta en los servicios estatales de salud y líderes comunitarios. Los datos fueron analizados desde una perspectiva antropológica y económica. RESULTADOS: La descentralización ocurrió de forma heterogénea en cada estado, observándose una transferencia de responsabilidades de la federación a los estados, más no así una ruptura con la dependencia del nivel central - federal. Las reformas impulsadas desde el nivel federal para crear un esquema fundamentado en principios de subsidiaridad financiera y democratización en salud enfrentan retos políticos y organizacionales para su consolidación. CONCLUSIONES: El enfoque antropológico muestra la relevancia de considerar factores organizacionales, políticos y económicos como parte del proceso de descentralización.

Electrophoretic protein patterns and numerical analysis of Candida albicans from the oral cavities of healthy children

The aim of this research was to evaluate the protein polymorphism degree among seventy-five C. albicans strains from healthy children oral cavities of five socioeconomic categories from eight schools (private and public) in Piracicaba city, São Paulo State, in order to identify C. albicans subspecies and their similarities in infantile population groups and to establish their possible dissemination route. Cell cultures were grown in YEPD medium, collected by centrifugation, and washed with cold saline solution. The whole-cell proteins were extracted by cell disruption, using glass beads and submitted to SDS-PAGE technique. After electrophoresis, the protein bands were stained with Coomassie-blue and analyzed by statistics package NTSYS-pc version 1.70 software. Similarity matrix and dendrogram were generated by using the Dice similarity coefficient and UPGMA algorithm, respectively, which made it possible to evaluate the similarity or intra-specific polymorphism degrees, based on whole-cell protein fingerprinting of C. albicans oral isolates. A total of 13 major phenons (clusters) were analyzed, according to their homogeneous (socioeconomic category and/or same school) and heterogeneous (distinct socioeconomic categories and/or schools) characteristics. Regarding to the social epidemiological aspect, the cluster composition showed higher similarities (0.788 < S D < 1.0) among C. albicans strains isolated from healthy children independent of their socioeconomic bases (high, medium, or low). Isolates of high similarity were not found in oral cavities from healthy children of social stratum A and D, B and D, or C and E. This may be explained by an absence of a dissemination route among these children. Geographically, some healthy children among identical and different schools (private and public) also are carriers of similar strains but such similarity was not found among other isolates from children from certain schools. These data may reflect a restricted dissemination route of these microorganisms in some groups of healthy scholars, which may be dependent of either socioeconomic categories or geographic site of each child. In contrast to the higher similarity, the lower similarity or higher polymorphism degree (0.499 < S D < 0.788) of protein profiles was shown in 23 (30.6%) C. albicans oral isolates. Considering the social epidemiological aspect, 42.1%, 41.7%, 26.6%, 23.5%, and 16.7% were isolates from children concerning to socioeconomic categories A, D, C, B, and E, respectively, and geographically, 63.6%, 50%, 33.3%, 33.3%, 30%, 25%, and 14.3% were isolates from children from schools LAE (Liceu Colégio Albert Einstein), MA (E.E.P.S.G. "Prof. Elias de Melo Ayres"), CS (E.E.P.G. "Prof. Carlos Sodero"), AV (Alphaville), HF (E.E.P.S.G. "Honorato Faustino), FMC (E.E.P.G. "Prof. Francisco Mariano da Costa"), and MEP (E.E.P.S.G. "Prof. Manasses Ephraim Pereira), respectively. Such results suggest a higher protein polymorphism degree among some strains isolated from healthy children independent of their socioeconomic strata or geographic sites. Complementary studies, involving healthy students and their families, teachers, servants, hygiene and nutritional habits must be done in order to establish the sources of such colonization patterns in population groups of healthy children. The whole-cell protein profile obtained by SDS-PAGE associated with computer-assisted numerical analysis may provide additional criteria for the taxonomic and epidemiological studies of C. albicans.

Evaluation of GBV-C / HVG viremia in HIV-infected women

The present study aimed at standardizing a real-time quantitative polymerase chain reaction assay to evaluate the presence of GBV-C/HGV RNA. A "TaqMan" assay using primers and probe derived from the 5¢ NCR region was developed and validated. Two hundred and fifty-three plasma samples from HIV-infected women were tested for GBV-C viremia and antibody against the envelope protein 2. GBV-C RNA was detected in 22.5% of the patients whereas the antibody was identified in 25.3% of the cohort. Detection of viral RNA and of antibodies was mutually exclusive. Viral loads showed a mean of 1,777 arbitrary units / mL, being 1.1 and 13,625 arbitrary units / mL respectively the lowest and highest values measured. We conclude that the real-time quantitative polymerase chain reaction method developed is appropriate for the investigation of GBV-C RNA since it was shown to be highly specific and sensitive, as well as requiring few steps, preventing contamination and providing additional information as to the relative viremia of carriers, a parameter that must be included in studies evaluating the co-factors influencing the clinical outcome of HIV/AIDS.
