Spatial distribution of dengue incidence and socio-environmental conditions in Campinas, São Paulo State, Brazil, 2007

This study aimed to analyze the spatial distribution of dengue risk and its association with socio-environmental conditions. This was an ecological study of the counts of autochthonous dengue cases in the municipality of Campinas, São Paulo State, Brazil, in the year 2007, aggregated according to 47 coverage areas of municipal health centers. Spatial models for mapping diseases were constructed with Bayesian hierarchical models, based on Integrated Nested Laplace Approximation (INLA). The analyses were stratified according to two age groups, 0 to 14 years and above 14 years. The results indicate that the spatial distribution of dengue risk is not associated with socio-environmental conditions in the 0 to 14 year age group. In the age group older than 14 years, the relative risk of dengue increases significantly as the level of socio-environmental deprivation increases. Mapping of socio-environmental deprivation and dengue cases proved to be a useful tool for data analysis in dengue surveillance systems.

A anatomia e o ensino de anatomia no Brasil: a escola boveriana

There is little scholarly research on the history, teaching and research of human anatomy in Brazil. A broader vision of the progress of anatomy under different circumstances in the country is virtually non-existent, leaving researchers keen to study the subject insecure. This is compounded by the fact that the data available are not always reliable. This text retraces the development of the discipline of anatomy and its research and education in Brazil in general and São Paulo state in particular, which can largely be reduced to the action of the self-proclaimed Boverian school of anatomy, founded by Italian physician Alfonso Bovero at the same time as the Medical Faculty of the University of São Paulo.

Space-time cluster analysis of American visceral leishmaniasis in Bauru, Sao Paulo State, Brazil

A space-time analysis of American visceral leishmaniasis (AVL) in humans in the city of Bauru, Sao Paulo State, Brazil was carried out based on 239 cases diagnosed between June 2003 and October 2008. Spatial analysis of the disease showed that cases occurred especially in the city's urban areas. AVL annual incidence rates were calculated, demonstrating that the highest rate occurred in 2006 (19.55/100,000 inhabitants). This finding was confirmed by the time series analysis, which also showed a positive tendency over the period analyzed. The present study allows us to conclude that the disease was clustered in the Southwest side of the city in 2006, suggesting that this area may require special attention with regard to control and prevention measures.

Toll-like receptor 1 N248S single-nucleotide polymorphism is associated with leprosy risk and regulates immune activation during mycobacterial infection

Conflicting findings about the association between leprosy and TLR1 variants N248S and I602S have been reported. Here, we performed case-control and family based studies, followed by replication in 2 case-control populations from Brazil, involving 3162 individuals. Results indicated an association between TLR1 248S and leprosy in the case-control study (SS genotype odds ratio [OR], 1.81; P = .004) and the family based study (z = 2.02; P = .05). This association was consistently replicated in other populations (combined OR, 1.51; P < .001), corroborating the finding that 248S is a susceptibility factor for leprosy. Additionally, we demonstrated that peripheral blood mononuclear cells (PBMCs) carrying 248S produce a lower tumor necrosis factor/interleukin-10 ratio when stimulated with Mycobacterium leprae but not with lipopolysaccharide or PAM3cysK4. The same effect was observed after infection of PBMCs with the Moreau strain of bacillus Calmette-Guerin but not after infection with other strains. Finally, molecular dynamics simulations indicated that the Toll-like receptor 1 structure containing 248S amino acid is different from the structure containing 248N. Our results suggest that TLR1 248S is associated with an increased risk for leprosy, consistent with its hypoimmune regulatory function.

Regional differences in clinical care among patients with type 1 diabetes in Brazil: Brazilian Type 1 Diabetes Study Group

Background To determine the characteristics of clinical care offered to type 1 diabetic patients across the four distinct regions of Brazil, with geographic and contrasting socioeconomic differences. Glycemic control, prevalence of cardiovascular risk factors, screening for chronic complications and the frequency that the recommended treatment goals were met using the American Diabetes Association guidelines were evaluated. Methods This was a cross-sectional, multicenter study conducted from December 2008 to December 2010 in 28 secondary and tertiary care public clinics in 20 Brazilian cities in north/northeast, mid-west, southeast and south regions. The data were obtained from 3,591 patients (56.0% females and 57.1% Caucasians) aged 21.2 ± 11.7 years with a disease duration of 9.6 ± 8.1 years (<1 to 50 years). Results Overall, 18.4% patients had HbA1c levels <7.0%, and 47.5% patients had HbA1c levels ≥ 9%. HbA1c levels were associated with lower economic status, female gender, age and the daily frequency of self-blood glucose monitoring (SBGM) but not with insulin regimen and geographic region. Hypertension was more frequent in the mid-west (32%) and north/northeast (25%) than in the southeast (19%) and south (17%) regions (p<0.001). More patients from the southeast region achieved LDL cholesterol goals and were treated with statins (p<0.001). Fewer patients from the north/northeast and mid-west regions were screened for retinopathy and nephropathy, compared with patients from the south and southeast. Patients from the south/southeast regions had more intensive insulin regimens than patients from the north/northeast and mid-west regions (p<0.001). The most common insulin therapy combination was intermediate-acting with regular human insulin, mainly in the north/northeast region (p<0.001). The combination of insulin glargine with lispro and glulisine was more frequently used in the mid-west region (p<0.001). Patients from the north/northeast region were younger, non-Caucasian, from lower economic status, used less continuous subcutaneous insulin infusion, performed less SBGM and were less overweight/obese (p<0.001). Conclusions A majority of patients, mainly in the north/northeast and mid-west regions, did not meet metabolic control goals and were not screened for diabetes-related chronic complications. These results should guide governmental health policy decisions, specific to each geographic region, to improve diabetes care and decrease the negative impact diabetes has on the public health system.

Contributions from the systematic review of economic evaluations: the case of childhood hepatitis A vaccination in Brazil

The aim of this study was to present the contributions of the systematic review of economic evaluations to the development of a national study on childhood hepatitis A vaccination. A literature review was performed in EMBASE, MEDLINE, WOPEC, HealthSTAR, SciELO and LILACS from 1995 to 2010. Most of the studies (8 of 10) showed favorable cost-effectiveness results. Sensitivity analysis indicated that the most important parameters for the results were cost of the vaccine, hepatitis A incidence, and medical costs of the disease. Variability was observed in methodological characteristics and estimates of key variables among the 10 studies reviewed. It is not possible to generalize results or transfer epidemiological estimates of resource utilization and costs associated with hepatitis A to the local context. Systematic review of economic evaluation studies of hepatitis A vaccine demonstrated the need for a national analysis and provided input for the development of a new decision-making model for Brazil.

Fatores associados ao tabagismo em idosos: Inquérito de Saúde no Estado de São Paulo (ISA-SP)

O objetivo deste trabalho foi determinar a prevalência do hábito de fumar e os fatores associados em idosos. Estudo transversal de base populacional, com amostragem em múltiplos estágios, que envolveu 1.954 idosos com 60 anos ou mais, residentes em quatro áreas do Estado de São Paulo, Brasil. A prevalência de fumantes foi de 12,2%, sendo maior no sexo masculino, na faixa de 60 a 69 anos, nos estratos inferiores de renda, nos idosos com baixo peso corporal, nos que não praticavam atividade física de lazer, naqueles com depressão/ansiedade e que referiram não ser hipertensos, e a prevalência foi menor entre os evangélicos. Prevalências elevadas de fumantes foram observadas em idosos com história de AVC, câncer e doença pulmonar crônica. Os resultados alertam para a necessidade de intervenções eficazes dos serviços de saúde para a cessação do tabagismo em idosos, visto que muitos deles, mesmo com doenças relacionadas ao tabaco, não conseguem deixar de fumar, especialmente junto ao estrato SUS dependente, pois a prevalência do tabagismo é maior nos segmentos socioeconômicos mais desfavorecidos.

Custos hospitalares da meningite causada por Streptococcus pneumoniae na cidade de São José dos Campos, São Paulo, Brasil

O conhecimento dos custos hospitalares é de grande importância para os processos de tomada de decisão em saúde pública. O objetivo deste estudo foi estimar os custos hospitalares diretos relacionados à meningite pneumocócica em crianças com até 13 anos (inclusive), na cidade de São José dos Campos, São Paulo, Brasil, de janeiro de 1999 a dezembro de 2008. Foram obtidos dados de prontuários médicos. O cálculo foi realizado pelo método misto de mensuração das quantidades dos itens de custos e atribuição de valor aos itens consumidos (micro-costing e gross-costing). Os valores monetários referem-se a novembro de 2009, sendo expressos em reais. A análise das frequências e médias foi realizada pelo programa Epi Info versão 3.5.1. Foram notificados 41 casos. Os custos hospitalares diretos variaram de R$ 1.277,90 a R$ 19.887,56 (média = R$ 5.666,43), ou seja, 10 a 20 vezes maiores que o custo médio de internações pago pelo SUS. Os custos dos honorários profissionais foram os mais relevantes, seguidos pelos custos dos medicamentos, procedimentos, materiais e exames laboratoriais.
