Alcohol consumption in homicide victims in the city of Sao Paulo

Aims To assess the association between alcohol use and victimization by homicide in individuals autopsied at the Institute of Legal Medicine in Sao Paulo, Brazil. Design Cross-sectional study. Setting Excessive consumption of alcohol is a serious public health issue and a major factor in triggering violent situations, which suggests a strong association between alcohol ingestion and becoming a victim of homicide. Participants Data from 2042 victims of homicides in 2005 were obtained from medical examiner reports. Measurements The victim`s gender, age, ethnicity and blood alcohol concentration (BAC) were collected. The method of death and homicide circumstances, as well as the date, time and place of death were also studied. Findings Alcohol was detected in blood samples of 43% of the victims, and mean BAC levels were 1.55 +/- 0.86 g/l. The prevalence of positive BAC levels was higher among men (44.1%) than women (26.6%), P < 0.01. Firearms caused most of the deaths (78.6%), and alcohol consumption was greater among victims of homicide by sharp weapons (P < 0.01). A greater proportion of victims with positive BAC were killed at weekends compared to weekdays (56.4 and 38.5%, respectively; P < 0.01), and the correlation between homicide rates and the average BAC for the central area of the city was positive (r(s) = 0.90; P < 0.01). Conclusions These results highlight alcohol as a contributing factor for homicide victimization in the greatest urban center in South America, supporting public strategies and future research aiming to prevent homicides and violence related to alcohol consumption.

International study of temperature, heat and urban mortality: the `ISOTHURM` project

Background This study describes heat- and cold-related mortality in 12 urban populations in low- and middle-income countries, thereby extending knowledge of how diverse populations, in non-OECD countries, respond to temperature extremes. Methods The cities were: Delhi, Monterrey, Mexico City, Chiang Mai, Bangkok, Salvador, So Paulo, Santiago, Cape Town, Ljubljana, Bucharest and Sofia. For each city, daily mortality was examined in relation to ambient temperature using autoregressive Poisson models (2- to 5-year series) adjusted for season, relative humidity, air pollution, day of week and public holidays. Results Most cities showed a U-shaped temperature-mortality relationship, with clear evidence of increasing death rates at colder temperatures in all cities except Ljubljana, Salvador and Delhi and with increasing heat in all cities except Chiang Mai and Cape Town. Estimates of the temperature threshold below which cold-related mortality began to increase ranged from 15 degrees C to 29 degrees C; the threshold for heat-related deaths ranged from 16 degrees C to 31C. Heat thresholds were generally higher in cities with warmer climates, while cold thresholds were unrelated to climate. Conclusions Urban populations, in diverse geographic settings, experience increases in mortality due to both high and low temperatures. The effects of heat and cold vary depending on climate and non-climate factors such as the population disease profile and age structure. Although such populations will undergo some adaptation to increasing temperatures, many are likely to have substantial vulnerability to climate change. Additional research is needed to elucidate vulnerability within populations.

Dental caries in adolescents from public schools in Maputo, Mozambique

Aim: To assess dental caries prevalence in adolescents at urban and sub-urban areas of Maputo-City, Mozambique and to identify its relationship with dental fluorosis, dental plaque, nutritional status, frequency of sugar consumption and the concentration of fluoride in public water supply. Methods: Subjects (n=601) were randomly selected from five urban schools and five sub-urban schools. Clinical examinations were performed under standardised conditions by a trained examiner using DMFT index, SiC index, fluorosis index, PHP, BMI, a sugar consumption questionnaire and water supply analysis. The bivariate analysis and Pearson correlation was used (p<0.05). Results: The mean (DMFT) was 0.9 (+/- 1.65 SD). Children in urban schools showed less dental caries (0.8 +/- 1.49SD) than children in sub-urban schools (1.1 +/- 1.80SD, p=0.03). Only 8.15% had very mild to moderate fluorosis but most presented poor oral hygiene. Cases of malnutrition were found in more sub-urban schools (n = 109; 36.22%) than in urban schools (n = 66; 22.00%) (p=0.03). The frequency of sugar consumption was higher among urban children compared to suburban schools (p<0.00). The level of fluoride in water consumption in urban schools was 0.4 ppmF, above the level of fluoride in sub-urban schools, 0.2 ppmF. Conclusion: Dental caries should not be considered a major oral health problem in Maputo at the moment. However the data suggest the implementation of a population strategy to reduce dental caries rates, in children of both urban and sub-urban areas, in Maputo.

O papel da cidade de Viçosa-MG na rede urbana : a especialização funcional de uma cidade média mineira

Rede é o nome dado para se referenciar qualquer forma que seja composta por linhas interligadas por pontos, sendo assim essa denominação é utilizada para participar de nomes e conceitos em diversas área do conhecimento. Na geografia isso não ocorre de forma diferente. As redes geográficas são a denominação dada as ligações feitas no espaço articuladas por pontos, notadamente são usadas para se fazer referência a redes materiais, mas podem ser mais imateriais ou abstratas a depender do objeto de pesquisa e do adjetivo adotado. A noção de redes urbanas nasceu vinculada aos objetos materiais, entretanto com a evolução da técnica passou a abranger objetos cada vez mais virtuais. As redes urbanas são compostas pelo conjunto de cidades, cada qual com sua centralidade representadas por pontos ou nós na rede, e pelas ligações entre elas, rodovias, hidrovias, infovias etc. As cidades que compõem a rede, por mais semelhanças que possam ter entre si, tem diferentes tipos e graus de centralidade, de poder de atração de pessoas, de recursos; sendo uma região de influência singular, que muda de tempos em tempos, face a evolução do território onde se insere. Tanto as centralidades quanto as redes de urbanas estão em constante mudança, necessitando sempre de atualização tornando o estudo das redes e das centralidades uma questão sempre nova; em especial quando considerado um território tão vasto e complexo como o brasileiro. Neste trabalho relatamos os resultados do estudo das especificidades da centralidade da cidade de Viçosa, que está localizada no interior do estado de Minas Gerais, Brasil. Este estudo fez uso de dados numéricos, fotográficos e cartográficos coletados em diversos momentos da evolução do município e da região onde este se insere, que revelaram as mudanças de qualidade e de intensidade na centralidade dessa cidade, hoje tipificada como média ou intermediária, inserida na rede urbana mineira. No período compreendido entre os anos de 1850 e 1930, Viçosa passou de uma inexpressiva localidade rural, a importante centro de produção de café, galgando ganhos políticos nesse período. Seguiu-se um período de menor pujança, por cerca de setenta anos, para depois, na virada do século XX para XXI, ressurgi como uma localidade especializada em oferecer serviços, notadamente vinculados ao ensino superior e à produção de ciência e tecnologia. Essa nova centralidade, ao contrário do que muitas vezes ocorre, não foi fruto nem de um recurso natural inerente ao território e nem, tão pouco, pela atuação de grandes grupos capitalistas. Foi galgado principalmente pela atuação do Estado que construiu ali as bases de uma especialização funcional, através da implantação de uma universidade pública.

Expansão urbana e o Programa Minha Casa, Minha Vida na região metropolitana da Grande Vitória

Discute as contribuições do Programa Minha Casa Minha Vida (PMCMV) no processo de formação e expansão do espaço urbano da Região Metropolitana da Grande Vitória (RGMV), analisando especificamente a produção das moradias destinadas às famílias de baixa renda até R$ 1.600,00. Busca compreender as características operacionais do Programa e suas implicações sobre o espaço socialmente construído e na vida cotidiana das pessoas. A metodologia analítica foi estruturada com base em dados quantitativos, obtidos em órgãos públicos, sobre a produção habitacional desde o lançamento do Programa (2009) até janeiro de 2014. Os dados foram distribuídos por território e faixa de rendimento das famílias. Como estudo de caso foram pesquisadas três áreas na RMGV, nos municípios de Cariacica, Vila Velha e Vitória por possuírem projetos relevantes do PMCMV em diferentes fases de execução. A pesquisa abrange projetos distribuídos em cinco fases de execução (previstos, em aprovação, aprovados, em construção e entregues). Foram realizadas entrevistas semi-estruturadas com moradores do conjunto habitacional do PMCMV em Vitória; moradores vizinhos aos empreendimentos do PMCMV em Vila Velha; comerciantes; presidente da associação de moradores de bairros; empregados das construtoras e servidores públicos. Foram feitas pesquisas de campo nas áreas selecionadas e nos territórios do entorno de onde estão sendo implantadas as moradias de interesse social. O Programa tem alcançado resultados expressivos: sendo 3.2 milhões de unidades foram contratadas e 1.5 milhão entregues em 5 anos no Brasil. No mesmo período foram 46.879 e 15.295 no Espírito Santo e na RMGV foram 25.919 e 6.958 unidades contratadas e entregues respectivamente. O PMCMV continua a reproduzir historicamente contradições inerentes às políticas habitacionais antecedentes como submissão às estratégias do mercado capitalista e à reprodução de um modelo de crescimento urbano caracterizado pela segregação socioespacial, além de promover a ocupação de novos espaços periféricos das cidades atuando como vetor de expansão urbana da RMGV.

A modernização do atraso : os fundamentos da urbanização de Vitória-1889-1930

Esta dissertação volta-se para a investigação da modernização da cidade de Vitória durante a passagem do século XIX ao XX. Trata-se, especificamente, da tentativa de compreender a modernização de Vitória no seu conteúdo arcaico, no sentido de, no conjunto das estratégias do poder, preservarem-se interesses de estruturas sociais anteriores, para um novo contexto econômico e sociopolítico. O referencial teórico de análise pressupôs apreender a cidade (seu espaço construído) articulada à estrutura econômica, enquanto condições urbanas necessárias à reprodução do capital. Para tal efeito, foi necessário compreender as implicações da metamorfose da riqueza, representada anteriormente pela propriedade do escravo e transferida para a propriedade da terra. Nessa tarefa, investigamos a hegemonia dos interesses da instância mercantil-exportadora do capital que dominou o aparelho de Estado e dirigiu o processo. A interferência dessa fração do capital no processo foi compreendida a partir da estruturação do poder no Espírito Santo processada na reorganização das bases da produção de café na transição do trabalho escravo para o livre. Através da modernização da cidade, foram criadas novas alternativas de valorização do capital por intermédio da construção da cidade (habitações, edifícios públicos, infraestrutura e serviços urbanos). Contudo, não se verificou de forma significativa desdobramento do excedente acumulado na esfera do comércio em atividades produtivas modernas (multiplicadoras da riqueza). Nesse processo, surge a perspectiva de a valorização da propriedade imobiliária como expressão do desenvolvimento das condições gerais da produção e da reprodução do trabalho possibilitar rendas futuras crescentes ao capital. O que indica uma urbanização fundamentalmente dominada pelos interesses mercantil-exportadores e patrimonialistas, revelando um forte traço de atraso da modernização da cidade em seu papel de centro comercial da economia regional.

Risk factors for perinatal mortality in an urban area of Southern Brazil, 1993

INTRODUCTION: Although there was a considerable reduction in infant mortality in Pelotas, Rio Grande do Sul in the last decade, its perinatal causes were reduced only by 28%. The associated factors of these causes were analised. MATERIAL AND METHOD: All hospital births and perinatal deaths were assessed by daily visits to all the maternity hospitals in the city, throughout 1993 and including the first week of 1994. RESULTS: The perinatal mortality rate was 22.1 per thousand births. The multivariate analysis showed the following risk factors: low socioeconomic level, male sex and maternal age above 35 years . Among multigravidae women, the fetal mortality rate was significantly increased for mothers with a previously low birthweight and a previous stillbirth. For early neonatal mortality the risk was significantly increased by a smaller number of antenatal visits than 5 and low birthweight. CONCLUSIONS: Main risk factors for perinatal mortality: low socioeconomic level, maternal age above 35 years and male sex. For early neonatal mortality the risk was significantly increased by a smaller number of antenatal visits than 5 and low birthweight.

Infant mortality rates according to socioeconomic status in a Brazilian city

OBJECTIVE: Data from municipal databases can be used to plan interventions aimed at reducing inequities in health care. The objective of the study was to determine the distribution of infant mortality according to an urban geoeconomic classification using routinely collected municipal data. METHODS: All live births (total of 42,381) and infant deaths (total of 731) that occurred between 1994 and 1998 in Ribeirão Preto, Brazil, were considered. Four different geoeconomic areas were defined according to the family head's income in each administrative urban zone. RESULTS: The trends for infant mortality rate and its different components, neonatal mortality rate and post-neonatal mortality rate, decreased in Ribeirão Preto from 1994 to 1998 (chi-square for trend, p<0.05). These rates were inversely correlated with the distribution of lower salaries in the geoeconomic areas (less than 5 minimum wages per family head), in particular the post-neonatal mortality rate (chi-square for trend, p<0.05). Finally, the poor area showed a steady increase in excess infant mortality. CONCLUSIONS: The results indicate that infant mortality rates are associated with social inequality and can be monitored using municipal databases. The findings also suggest an increase in the impact of social inequality on infant health in Ribeirão Preto, especially in the poor area. The monitoring of health inequalities using municipal databases may be an increasingly more useful tool given the continuous decentralization of health management at the municipal level in Brazil.

Spatial analysis of urban violence based on emergency room data

OBJECTIVE: To estimate the spatial intensity of urban violence events using wavelet-based methods and emergency room data. METHODS: Information on victims attended at the emergency room of a public hospital in the city of São Paulo, Southeastern Brazil, from January 1, 2002 to January 11, 2003 were obtained from hospital records. The spatial distribution of 3,540 events was recorded and a uniform random procedure was used to allocate records with incomplete addresses. Point processes and wavelet analysis technique were used to estimate the spatial intensity, defined as the expected number of events by unit area. RESULTS: Of all georeferenced points, 59% were accidents and 40% were assaults. There is a non-homogeneous spatial distribution of the events with high concentration in two districts and three large avenues in the southern area of the city of São Paulo. CONCLUSIONS: Hospital records combined with methodological tools to estimate intensity of events are useful to study urban violence. The wavelet analysis is useful in the computation of the expected number of events and their respective confidence bands for any sub-region and, consequently, in the specification of risk estimates that could be used in decision-making processes for public policies.

Severity and exposure associated with tsunami actions in urban waterfronts: the case of Lisbon, Portugal

The Tagus estuary is bordered by the largest metropolitan area in Portugal, the Lisbon capital city council. It has suffered the impact of several major tsunamis in the past, as shown by a recent revision of the catalogue of tsunamis that struck the Portuguese coast over the past two millennia. Hence, the exposure of populations and infrastructure established along the riverfront comprises a critical concern for the civil protection services. The main objectives of this work are to determine critical inundation areas in Lisbon and to quantify the associated severity through a simple index derived from the local maximum of momentum flux per unit mass and width. The employed methodology is based on the mathematical modelling of a tsunami propagating along the estuary, resembling the one occurred on the 1 November of 1755 that followed the 8.5 M-w Great Lisbon Earthquake. The employed simulation tool was STAV-2D, a shallow-flow solver coupled with conservation equations for fine solid phases, and now featuring the novelty of discrete Lagrangian tracking of large debris. Different sets of initial conditions were studied, combining distinct tidal, atmospheric and fluvial scenarios, so that the civil protection services were provided with comprehensive information to devise public warning and alert systems and post-event mitigation intervention. For the most severe scenario, the obtained results have shown a maximum inundation extent of 1.29 km at the AlcA cent ntara valley and water depths reaching nearly 10 m across Lisbon's riverfront.

Transient Spaces: unsettling boundaries and norms at the cultural event Noc Noc, Guimarães, Portugal

Cities are increasingly expected to be creative, inventive and to exhibit intense expressivity. In the past decades many cities have experienced growing pressure to produce and stage cultural events of different sorts and to develop new strategies that optimize competitive advantages, in order to promote themselves and to boost and sell their image. Often these actions have relied on heavy public investment and major private corporation sponsoring, but it is not always clear or measured how successful and reproductive these investments have been. In the context of strained public finances and profound economic crisis of European peripheral countries, events that emerge from local communities and have low budgets, which manage to create significant fluxes of visitors and visibility, assume an increased interest. In order to reflect and sketch possible answers, we look to an emerging body of literature concerning creative cities, and we focus on the organisation of a particular cultural event and its impact and assimilation into a medium size Portuguese city. This paper looks at the two editions (2011 and 2012) of one of such events – Noc Noc – organized by a local association in the city of Guimarães, Portugal. Inspired by similar events, Noc Noc is based on creating transient spaces of culture which are explored by artists and audiences, by transforming numerous homes into ephemeral convivial and playful social ‘public’ environments. The event is based on a number of cultural venues/homes scattered around the old and newer city, which allows for an informal urban exploration and an autonomous rambling and getting lost along streets. This strategy not only disrupts the cleavages between public and private space permitting for various transgressions, but it also disorders normative urban experiences and unsettles the dominant role of the city council as the culture patron of the large majority of events. Guimarães, an UNESCO World Heritage City was the European Capital of Culture in 2012, with a public investment of roughly 73 million euro. By interviewing a sample of people who have hosted these transitory art performances and exhibitions, sometimes doubling as artists, the events’ organizers and by experience both editions of the event, this paper illustrates how urban citizens’ engagement and motivations in a low budget cultural event can strengthen community ties. Furthermore, it also questions the advantages of large scale high budget events, and how this event may be seen as unconscious counter movement against a commodification of cultural events and everyday urban experience at large, engaging with the concepts of staging and authenticity.

Prevalence of rubella antibodies in a non-immunized urban population, São Paulo, Brazil

The prevalence of rubella antibodies was evaluated through a ramdom Seroepidemiological survey in 1400 blood samples of 2-14 year old children and in 329 samples of umbilical cord serum. Rubella IgG antibodies were detected by ELISA, and the sera were collected in 1987, five years before the mass vaccination campaign with measles-mumps-rubella vaccine carried out in the city of São Paulo in 1992. A significant increase in prevalence of rubella infection was observed after 6 years of age, and 77% of the individuals aged from 15 to 19 years had detectable rubella antibodies. However, the seroprevalence rose to 90.5% (171/189) in cord serum samples from children whose mothers were 20 to 29 years old, and reached 95.6% in newborns of mothers who were 30 to 34 years old, indicating that a large number of women are infected during childbearing years. This study confirms that rubella infection represents an important Public Health problem in São Paulo city. The data on the seroprevalence of rubella antibodies before the mass vaccination campaign reflects the baseline immunological status of this population before any intervention and should be used to design an adequate vaccination strategy and to assess the Seroepidemiological impact of this intervention.
