A gestão de políticas públicas em saúde da divisão de vigilância em saúde da secretaria de estado de saúde pública - SESPA no combate do HIV/AIDS no estado do Pará - um estudo de caso

A presente dissertação teve como objetivo compreender como se promove a Gestão da Divisão de Vigilância Sanitária pela Secretaria de Estado de Saúde Pública/SESPA no combate do HIV/AIDS no Estado do Pará. A pesquisa contemplou o processo de Gestão de Políticas Públicas em Saúde da Divisão de Vigilância em Saúde da Secretaria de Estado de Saúde Pública – SESPA no combate do HIV/AIDS no Estado do Pará, destacando os resultados dessa gestão nos casos notificados. Tratou-se de um estudo descritivo, cujos dados foram coletados a partir de levantamento bibliográfico e documental com aplicação de questionário na Divisão de Vigilância em Saúde da Secretaria do Estado de Saúde Pública/SESPA. O referencial teórico enfocou aspectos da contextualização da Gestão Pública e Privada, assim como fez referencia a Gestão de Políticas Públicas em Saúde em Portugal e no Brasil. Os resultados mostraram que a Gestão da Divisão de Vigilância Sanitária /SESPA consiste em uma Gestão Pública que realiza suas atividades sobre uma estrutura burocrata e centralizada impedindo que a mesma supra adequadamente, enquanto organização, às demandas do Estado do Pará e aos desafios impostos pelo HIV/AIDS, que se reafirma como assunto de saúde pública. Como conclusão, o estudo evidenciou que Gestão da Divisão da Vigilância em Saúde da Secretaria de Estado de Saúde Pública/SESPA no combate do HIV/AIDS não promoveu adequadamente suas ações, apresentando resultados satisfatórios, pois necessita de melhores políticas públicas que propiciem ações para o cumprimento de suas metas, fortalecendo a capacidade de organização e de articulação, como a redução efetiva das vulnerabilidades sociais e políticas que agenciam a expansão da epidemia, crescentemente associada às desigualdades sociais que vigoram no Estado do Pará.

All Hands on Deck: Transdisciplinary Approaches to Emerging Infectious Disease

The increasing burden of emerging infectious diseases worldwide confronts us with numerous challenges, including the imperative to design research and responses that are commensurate to understanding the complex social and ecological contexts in which infectious diseases occur. A diverse group of scientists met in Hawaii in March 2005 to discuss the linked social and ecological contexts in which infectious diseases emerge. A subset of the meeting was a group that focused on ‘‘transdisciplinary approaches’’ to integrating knowledge across and beyond academic disciplines in order to improve prevention and control of emerging infections. This article is based on the discussions of that group. Here, we outline the epidemiological legacy that has dominated infectious disease research and control up until now, and introduce the role of new, transdisciplinary and systems-based approaches to emerging infectious diseases.Wedescribe four cases of transboundary health issues and use them to discuss the potential benefits, as well as the inherent difficulties, in understanding the social–ecological contexts in which infectious diseases occur and of using transdisciplinary approaches to deal with them.

Disease progression in heterosexual patients infected with closely related subtype B strains of HIV type 1 with differing coreceptor usage properties

Previously we described a heterosexual outbreak of HIV-1 subtype B in a town in the north of England (Doncaster) where 11 of 13 infections were shown to be linked by phylogenetic analysis of the env gp120 region. The 11 infections were related to a putative index case, Don1, and further divided into two groups based on the patients' disease status, their viral sequences, and other epidemiological information. Here we describe two further findings. First, we found that viral isolates and gp120 recombinant viruses derived from patients from one group used the CCR5 coreceptor, whereas viruses from the other group could use both the CCR5 and CXCR4 coreceptors. Patients with the X4/R5 dual tropic strains were symptomatic when diagnosed and progressed rapidly, in contrast to the other patient group that has remained asymptomatic, implying a link between the tropism of the strains and disease outcome. Second, we present additional sequence data derived from the index case, demonstrating the presence of sequences from both clades, with an average interclade distance of 9.56%, providing direct evidence of a genetic link between these two groups. This new study shows that Don1 harbored both strains, implying he was either dually infected or that over time intrahost diversification from the R5 to R5/X4 phenotype occurred. These events may account for/have led to the spread of two genetically related strains with different pathogenic properties within the same heterosexual community.

Spatial-temporal aspects of cost-benefit analysis for park management: an example from Khao Yai National Park, Thailand

Using a model calibrated to Khao Yai National Park in Thailand, this paper highlights the importance of generating explicitly spatial and temporal data for developing management plans for tropical protected forests. Spatial and temporal cost-benefit analysis should account for the interactions between different land uses – such as the benefits of contiguous areas of preserved land and edge effects – and the realities of villagers living near forests who rely on extracted resources. By taking a temporal perspective, this paper provides a rare empirical assessment of the importance of quasi-option values when determining optimal management plans.

Impact of a nutritional counseling program on prevention of HAART-related metabolic and morphologic abnormalities

The advent of highly active antiretroviral therapy (HAART) improved HIV infection prognosis. However, adverse metabolic and morphologic effects emerged, highlighting a lack of investigation into the role of nutritional interventions among this population. The present study evaluated the impact of a nutritional counseling program on prevention of morphologic and metabolic changes in patients living with HIV/AIDS receiving HAART. A 12-month randomized clinical trial was conducted with 53 adults of both genders in use of HAART. Subjects were allocated to either an intervention group (IG) or a control group (CG). Nutritional counseling was based on the promotion of a healthy diet pattern. Anthropometrical, biochemical, blood pressure, and food intake variables were assessed on four separate occasions. Sub scapular skin-fold results showed a significant tendency for increase between time 1 (Mean IG = 14.9 mm; CG = 13.6 mm), time 3 (Mean IG = 16.7 mm; CG = 18.2 mm), and time 4 (Mean IG = 16.4 mm; CG = 17.7 mm). Lipid percentage intake presented a greater increase among controls (time 1 mean = 26.3%, time 4 mean = 29.6%) than among IG subjects (time 1 mean = 29.1%, time 4 mean = 28.9%). Moreover, participants allocated to the IG presented an increase in dietetic fiber intake of almost 10 grams. The proposed nutritional counseling program proved to be effective in improving diet by reducing fat consumption and increasing fiber intake.

The game of contacts: Estimating the social visibility of groups

Estimating the sizes of hard-to-count populations is a challenging and important problem that occurs frequently in social science, public health, and public policy. This problem is particularly pressing in HIV/AIDS research because estimates of the sizes of the most at-risk populations-illicit drug users, men who have sex with men, and sex workers-are needed for designing, evaluating, and funding programs to curb the spread of the disease. A promising new approach in this area is the network scale-up method, which uses information about the personal networks of respondents to make population size estimates. However, if the target population has low social visibility, as is likely to be the case in HIV/AIDS research, scale-up estimates will be too low. In this paper we develop a game-like activity that we call the game of contacts in order to estimate the social visibility of groups, and report results from a study of heavy drug users in Curitiba, Brazil (n = 294). The game produced estimates of social visibility that were consistent with qualitative expectations but of surprising magnitude. Further, a number of checks suggest that the data are high-quality. While motivated by the specific problem of population size estimation, our method could be used by researchers more broadly and adds to long-standing efforts to combine the richness of social network analysis with the power and scale of sample surveys.
