São Paulo urban health index: measuring and mapping health disparities / Índice de saúde urbana de São Paulo: medindo e mapeando disparidades em saúde

ABSTRACT: Objective: To calculate and map the health inequalities in the city of São Paulo using the Urban Health Index (UHI) methodology. Methods: Seven indicators were selected from the Brazilian census: (1) proportion of households with access to sewage systems, (2) proportion of households served by regular waste collection, (3) proportion of households with two or more toilets, (4) proportion of households receiving tap water, (5) average income per household, (6) percentage of white people, and (7) literacy rate. Based on the UHI methodology, all health indicators were standardized and aggregated into a single metric at the census tract level. The UHI scores were ranked and plotted. The disparity ratio and the graph slope were calculated. The correlation between indicators was tested. Results were geocoded to produce a map of health risks. Results: The distribution of index values showed a linear middle section and deviations at each end. The disparity ratio found was 2.95, while the slope was 0.30. All indicators were significantly correlated. The map displayed a typical pattern of health inequality between the downtown and the periphery. The tracts located in the city's downtown had higher UHI values than those on the outskirts. Conclusions: The results of this study presented a visual distribution of health disparities in the city of São Paulo, proving to be a valuable method for identifying areas that require public health attention.

Resumo: Objetivo: Calcular e mapear as desigualdades em saúde na cidade de São Paulo por meio da metodologia do índice de saúde urbana (UHI). Métodos: Sete indicadores foram selecionados do censo brasileiro: (1) proporção de domicílios com acesso a esgoto, (2) proporção de domicílios com coleta regular de lixo, (3) proporção de domicílios com dois ou mais banheiros, (4) proporção de domicílios que recebem água encanada, (5) renda média por domicílio, (6) porcentagem de pessoas brancas e (7) taxa de alfabetização. Usando a metodologia UHI, todos os indicadores de saúde foram padronizados e agregados em uma única métrica para o setor censitário. Os valores de UHI foram classificados e plotados. A razão de disparidade e a inclinação do gráfico foram calculadas. A correlação entre os indicadores foi testada. Os resultados foram geocodificados, produzindo um mapa de risco à saúde. Resultados: A distribuição dos valores do índice apresentou uma seção intermediária linear e desvios nas extremidades. A taxa de disparidade encontrada foi de 2,95, enquanto o coeficiente angular foi 0,30. Todos os indicadores apresentaram correlação significativa. O mapa exibiu um arranjo característico de desigualdade em saúde entre o centro e a periferia. Os setores localizados na região central da cidade apresentaram valores de UHI mais elevados do que os da periferia. Conclusão: Os resultados deste estudo apresentaram uma distribuição visual das disparidades de saúde na cidade de São Paulo, demonstrando ser um método valioso para a identificação de áreas que requerem atenção da saúde pública.

Spatial analysis and climatic factors related to dengue in a small municipality of São Paulo, Brazil / Análise espacial e fatores climáticos relacionados à dengue, em município de pequeno porte de São Paulo, Brasil

Objective: to analyze the relationship of climatic variables, temperature and rainfall, - with dengue, in addition to identifying possible areas of greater spatial concentration of confirmed dengue cases. Methods: This is an ecological study with secondary data in the city of Ubirajara / SP. The confirmed cases of Dengue, assumed as an outcome, were obtained from the Aging and Notification Information System (SINAN) of the Ministry of Health; while the climatic data were used as independent variables and temperature and precipitation were provided by IPMet - Center of Meteorology of Bauru / SP, from 2007 to 2015. Pearson's correlation (r) was used for statistical analyzes. The addresses were geocoded and related to the digital cartoFigureic base of the municipality through the software QGIS and elaborated the thematic map through the kernel intensity estimator. Results: 187 cases of dengue were reported in the study period, with 119 cases (63.7%) occurring in 2015 with an incidence coefficient of 25.39 cases per 1,000 inhabitants. Mean annual temperature correlated positively with dengue and (r) (Pearson) cases = 0.6889, p = 0.0401 (α = Type I error) and ß = 0.6652 (Type II error). The Kernel map identified four areas of greatest concentration for dengue transmission. Conclusions: The relationship between temperature increase and dengue cases requires adequate responses from the institutions, with continuous monitoring of trends, construction of predictive models for the formulation of plans by using spatial analysis in the identification of the priority areas for actions that will be performed.

Objetivo: analisar a relação das variáveis climáticas, temperatura e precipitação pluviométrica, com a dengue, além de identificar possíveis áreas de maior concentração espacial de casos confirmados de dengue. Métodos: Trata-se de um estudo ecológico com dados secundários do município de Ubirajara/ SP. Os casos confirmados de Dengue, assumidos como desfecho, foram obtidos junto ao Sistema de Informação de Agravos e Notificações (SINAN) do Ministério da Saúde; enquanto os dados climáticos utilizados como variáveis independentes foram temperatura e precipitação, os quais foram fornecidos pelo Centro de Meteorologia de Bauru/ SP - IPMet, no período de 2007 a 2015. Utilizou- se a correlação Pearson (r) para as análises estatísticas. Os endereços foram geocodificados e relacionados com a base cartográfica digital do município, por meio do software QGIS. Foi elaborado o mapa temático segundo o estimador de intensidade de Kernel. Resultados: Foram notificados 187 casos de dengue no período do estudo; no entanto, somente em 2015 registraram-se 119 casos (63,7%), com um coeficiente de incidência de 25,39 casos por 1.000 habitantes. A temperatura média anual se correlacionou positivamente com os casos de dengue e r (Pearson) = 0,6889, p = 0,0401 (α = Erro tipo I) e ß = 0,6652 (Erro tipo II). O mapa de Kernel identificou quatro áreas de maior concentração para a transmissão da dengue. Conclusões: A relação do aumento da temperatura com os casos de dengue exige respostas adequadas das instituições, como o acompanhamento permanente de tendências, de construção de modelos preditivos e de formulação de planos que façam uso de análise espacial na identificação de áreas prioritárias para as ações que serão realizadas.

Effect of prosthodontic planning on lateral occlusion scheme: a comparison between conventional and digital planning

Recently, digital wax-up is proposed as a tool to aid prosthodontic planning. However, there are no data about the effect of prosthodontic planning on lateral occlusion scheme. Objective : This study aims to evaluate the impact of conventional and digital prosthodontic planning on lateral occlusion scheme. Material and Methods : Dental models of 10 patients were collected. All models had Angle Class I occlusion and were undergoing prosthodontic treatment that would influence the lateral occlusion scheme. Each set of models had received both conventional wax-up and digital wax-up. In relation to the lateral occlusion scheme, the following variables were evaluated: the prevalence of the different lateral occlusion scheme, number of contacting teeth and percentage of each contacting tooth. Four excursive positions on the working side were included: 0.5, 1.0, 2.0 and 3.0 mm from the maximal intercuspation position. Results : The lateral occlusion scheme of the two wax-up models was subjected to alterations following excursion. There was a tendency for the prevalence of canine-guided occlusion to increase and for the prevalence of group function occlusion to decrease with increasing excursion. The number of contacting teeth was decreasing with the increasing magnitude of excursion. For the 0.5 mm and 1.0 mm positions, the two wax-ups had significantly greater contacts than the pre-treatment models, while at the 2.0 mm and 3.0 mm positions, all the models were similar. For all models, canines were the most commonly contacting teeth, followed by the teeth adjacent to them. No difference was observed between the two wax-ups in relation to the number of contacting teeth. Conclusion : Although the prosthodontic planning had influenced the pattern of the lateral occlusion scheme and contacts, there was no difference between the conventional and digital prosthodontic planning. .

30 Years of dental research in Australia and India: A comparative analysis of published peer review literature.

Background: A sustained program of research is an integral part of human-kind's efforts to improve oral health. In addition, dental research is a vital part of the development of a strong and prosperous dental education system and has been one of the three pillars of the higher education sector (Research, Education and Service) for a very long time. Aim: This study aims to examine the last 30 years of peer review published dental literature in both, Australia and India, and to define the trends in publication over that time. Materials and Methods: This study used the Pubmed database using a set of core dental words for the years 1980 to 2009. Detailed analysis of the year-by-year rates of publication was done using Microsoft Excel. Results: India is on a near exponential upward growth while Australia through the latter half of the last decade has been more stable in output. State-wise breakdown in both countries shows that the proportions are more consistent for Australia, but for India, a major number of publications can be traced to three states. Conclusion: It is expected that dental research in Australia will grow in the coming decade as the new dental schools embed their educational programs and mature to develop strong research profiles. However, India is becoming a significant force in the published peer review dental research literature, and is growing at a very rapid rate.

Qualitative research and dental public health.

The use of Qualitative Research (QR) methods are now getting common in various aspects of health and healthcare research and they can be used to interpret, explore, or obtain a deeper understanding of certain aspects of human beliefs, attitudes, or behavior through personal experiences and perspectives. The potential scope of QR in the field of dental public health is immense, but unfortunately, it has remained underutilized. However, there are a number of studies which have used this type of research to probe into some unanswered questions in the field of public health dentistry ranging from workforce issues to attitudes of patients. In recent health research, evidence gathered through QR methods provide understanding to the social, cultural, and economic factors affecting the health status and healthcare of an individual and the population as a whole. This study will provide an overview of what QR is and discuss its contributions to dental public health research.
