Monitoring Millennium Development Goals in Brazilian municipalities: challenges to be met in facing up to iniquities

The Healthy Cities and Agenda 21 programs improve living and health conditions and affect social and economic determinants of health. The Millennium Development Goals (MDG) indicators can be used to assess the impact of social agendas. A data search was carried out for the period 1997 to 2006 to obtain 48 indicators proposed by the United Nations and a further 74 proposed by the technical group for the MDGin Brazil. There is a scarcity of studies concerned with assessing the MDG at the municipal level. Data from Brazilian health information systems are not always consistent or accurate for municipalities. The lack of availability and reliable data led to the substitution of some indicators. The information systems did not always provide annual data; national household surveys could not be disaggregated at the municipal level and there were also modifications on conceptual definitions over time. As a result, the project created an alternative list with 29 indicators. MDG monitoring at the local community can be important to measure the performance of actions toward improvements in quality of life and social iniquities.

Entre a frieza, o cálculo e a "vida loka": violência e sofrimento no trajeto de um adolescente em cumprimento de medida socioeducativa

O conceito de sofrimento social caracteriza-se pela compreensão das situações de aflição e dor como experiências sociais e não como problemas individuais. Este trabalho analisa a natureza social e política do sofrimento de um adolescente em cumprimento de medida socioeducativa. Inspirado na abordagem de Veena Das, o artigo se apóia em "carne" e discurso para problematizar a relação entre cidadania e segmentos juvenis discriminados, que se manifesta nas ambiguidades das práticas institucionais presentes no fluxo de execução de medidas socioeducativas. O artigo analisa as contradições entre o objetivo institucional de evitar a reincidência de atos infracionais, auxiliando o adolescente a tornar-se um cidadão autônomo, e as narrativas e expressões corporais dos adolescentes durante o cumprimento das medidas. A trajetória aqui descrita leva ao reconhecimento de que o trânsito da medida de internação para as medidas em meio aberto se dá sob a tensão entre o discurso institucional de reorganizar a vida escolar, familiar e comunitária e a experiência cotidiana dos adolescentes, que segue marcada pela constante ameaça policial e pela privação de acessos a bens públicos. O cumprimento de medidas socioeducativas acaba por reforçar entre os adolescentes a aflição de serem socialmente tidos como suspeitos e fugitivos e, consequentemente, a incorporação de um lugar social particular, o de membro do "mundo do crime". O desempenho na vida cotidiana de um "estilo bandido" revela formas de resposta ao discurso dominante no sistema socioeducativo, contexto que indica o paradoxo do Estado brasileiro, que garante uma democracia formal enquanto viola direitos civis.

Diferenciais intra-urbanos de peso ao nascer no município de São Paulo

OBJETIVO: Identificar diferenciais intra-urbanos e fatores de risco na prevalência de baixo peso ao nascer. MÉTODOS: Foram utilizadas as informações das declarações de nascido vivo de mães residentes no município de São Paulo, obtidos do Sistema de Informação de Nascidos Vivos e Fundação Seade, para o período de 2002 e 2003, totalizando 368.980 nascidos vivos. Os endereços foram geo-referenciados em setores censitários e classificados em seis grupos de vulnerabilidade segundo o Índice Paulista de Vulnerabilidade Social. Para identificação dos possíveis fatores de risco empregou-se análise de regressão logística. RESULTADOS: Observou-se tendência de crescimento da prevalência de baixo peso ao nascer com aumento da vulnerabilidade (de 6,8% a 8,1%). Houve diferenças significativas entre os grupos quanto às características maternas, assistência pré-natal e da proporção de nascimentos de não pré-termo de baixo peso. No grupo de baixo peso não pré-termo, proxy da presença de retardo do crescimento intra-uterino, residir em áreas vulneráveis (1,29;1,17-1,43) e características socioeconômicas maternas desaforáveis, como mães adolescentes (1,13;1,04-1,22), baixa escolaridade (1,26;1,17-1,35) e elevada paridade (1,10;1,01-1,20) foram fatores de risco, assim como mães idosas (1,38;1,30-1,47), e sem companheiro (1,15;1,11-1,20). A ausência de pré-natal apresentou o maior risco de baixo peso para nascimentos de pré-termo (3,39;2,86-4,02) e não pré-termo (2,12;1,87-2,41). Houve redução de risco de baixo peso com o aumento de consultas de pré-natal para nascimentos de pré-termo e não pré-termo. CONCLUSÕES: Há diferenças de prevalência de baixo peso ao nascer segundo grupos de vulnerabilidade. A assistência pré-natal mostrou-se desigual segundo grupos de vulnerabilidade e seu elevado risco para o baixo peso ao nascer indica a importância de ampliar o acesso e qualidade dos serviços de saúde

Do school based food and nutrition policies improve diet and reduce obesity?

OBJECTIVE: To review the effectiveness of school food and nutrition policies world wide in improving the school food environment, student's dietary intake, and decreasing overweight and obesity. METHODS: Systematic review of published and unpublished literature up to November 2007 of three categories of nutrition policy; nutrition guidelines, regulation of food and/or beverage availability, and price interventions applied in preschools, primary and secondary schools. RESULTS: 18 studies met the inclusion criteria. Most evidence of effectiveness was found for the impact of both nutrition guidelines and price interventions on intake and availability of food and drinks, with less conclusive research on product regulation. Despite the introduction of school food policies worldwide few large scale or national policies have been evaluated, and all included studies were from the USA and Europe. CONCLUSION: Some current school policies have been effective in improving the food environment and dietary intake in schools, but there is little evaluation of their impact on BMI. As schools have been proposed worldwide as a major setting for tackling childhood obesity it is essential that future policy evaluations measure the long term effectiveness of a range of school food policies in tackling both dietary intake and overweight and obesity.

Condutas terapêuticas de atenção às famílias da população infantojuvenil atendida nos centros de atenção psicossocial infantojuvenis (CAPSI) do estado de São Paulo

Os Centros de Atenção Psicossociais Infantojuvenis (CAPSi) são elementos estratégicos da atenção pública em saúde mental ofertado para população infantojuvenil com sofrimento psíquico intenso e persistente. São articulados numa rede de atenção que extrapola o campo da saúde e interage com os recursos do território de determinada comunidade para promover inclusão social de crianças e adolescentes e conta para tanto também com a co-responsabilização das famílias, escolas e outros setores sociais. No rol de suas condutas terapêuticas há espaço reservado para o atendimento de familiares quando essa medida for necessária para aquela dirigida à clientela em foco. OBJETIVO: identificar condutas terapêuticas oferecidas às famílias de crianças e adolescentes atendidos nos CAPSi. MÉTODO: estudo transversal em crianças e adolescentes provenientes dos prontuários ativos, selecionados aleatoriamente, de 19 CAPSi do Estado de São Paulo no período de setembro de 2008 a fevereiro de 2009. A análisedescritiva foi apresentada por meio de tabelas de número e porcentagem. RESULTADOS: a mãe se revelou a principal cuidadora dessa população fora dos serviços. Contudo, há de se destacar a importante ausência de registros de atendimento ou propostas realizadas às famílias. CONSIDERAÇÕES FINAIS: a principal conduta indicada para as famílias são os atendimentos grupais, as famílias têm sido pouco privilegiadas nas condutas terapêuticas dentro dos projetos terapêuticos da população atendida. As falhas de registro nos prontuários pesquisados podem ser uma limitação do estudo. As ações são preponderantemente institucionais e as ofertas extramuros são raríssimas

Diferenciais de cárie dentária entre os índios Xavante de Mato Grosso, Brasil

O objetivo do estudo foi avaliar níveis de experiência de cárie entre subgrupos Xavante que vivem em diferentes Terras Indígenas (T.I.) no Estado de Mato Grosso, Brasil, a fim de investigar a presença de desigualdades no interior de uma mesma etnia indígena. Os dados foram coletados através de um censo de saúde bucal realizados em 2004. Das sete T.I. Xavante existentes, foram investigadas quatro (Pimentel Barbosa, Sangradouro, Areões e Marechal Rondon), nas quais foram selecionadas a maior aldeia de cada. Foram adotados os critérios preconizados pela Organização Mundial da Saúde, e utilizado o índice CPOS. Para mensurar as diferenças entre as T.I. foi estimada a razão de prevalência (RP) por meio de análise de regressão de Poisson, efetuada na faixa etária entre 6 e 34 anos para cada sexo, incluindo a idade como covariável. Nesta faixa etária, as perdas variaram entre 26 a 30 por cento. Pimentel Barbosa foi considerada como referência para comparações por apresentar menor prevalência de cárie em todas as faixas etárias analisadas. A maior disparidade foi notada entre as T.I. Pimentel Barbosa e Sangradouro, tanto em homens (RP 2,68- IC95 por cento 2,41 a 2,97) como em mulheres (RP 2,03- IC95 por cento 1,85 a 2,23). A RP do componente obturado em Areões e Marechal Rondon (diferença relativa a Pimentel Barbosa) é muito pequena em relação à carga de doença total nestas T.I., indicando menor presença de serviço odontológico restaurador. Conclui-se que a transição em saúde bucal não é homogênea entre os Xavante e que as diferenças podem estar associadas a particularidades do processo histórico de interação com a sociedade não-indígena (Continua) (Continuação) Determinantes locais e regionais, incluindo fatores demográficos, características econômicas e sócio-culturais específicas, acesso e utilização de serviços de saúde, podem ter determinado as desigualdades de ataque de cárie observadas entre os Xavante

Microbiological indicators for the assessment of performance in the hazard analysis and critical control points (HACCP) system in meat lasagna production

The HACCP system is being increasingly used to ensure food safety. This study investigated the validation of the control measures technique in order to establish performance indicators of this HACCP system in the manufacturing process of Lasagna Bolognese (meat lasagna). Samples were collected along the manufacturing process as a whole, before and after the CCPs. The following microorganism s indicator (MIs) was assessed: total mesophile and faecal coliform counts. The same MIs were analyzed in the final product, as well as, the microbiological standards required by the current legislation. A significant reduction in the total mesophile count was observed after cooking (p < 0.001). After storage, there was a numerical, however non-significant change in the MI count. Faecal coliform counts were also significantly reduced (p < 0.001) after cooking. We were able to demonstrate that the HACCP system allowed us to meet the standards set by both, the company and the Brazilian regulations, proved by the reduction in the established indicators

Effectiveness of a School-Based Intervention on Physical Activity for High School Students in Brazil: The Saude na Boa Project

Background: We evaluated the effectiveness of a school-based intervention on the promotion of physical activity among high school students in Brazil: the Saude no Boa project. Methods: A school-based, randomized trial was carried out in 2 Brazilian cities: Recife (northeast) and Florianopolis (south). Ten schools in each city were matched by size and location, and randomized into intervention or control groups. The intervention included environmental/organizational changes, physical activity education, and personnel training and engagement. Students age 15 to 24 years were evaluated at baseline and 9 months later (end of school year). Results: Although similar at baseline, after the intervention, the control group reported significantly fewer d/wk accumulating 60 minutes+ moderate-to-vigorous physical activity (MVPA) in comparison with the intervention group (2.6 versus 3.3, P < .001). The prevalence of inactivity (0 days per week) rose in the control and decreased in the intervention group. The odds ratio for engaging at least once per week in physical activity associated with the intervention was 1.83 (95% CI = 1.24-2.71) in the unadjusted analysis and 1.88 (95% CI = 1.27-2.79) after controlling for gender. Conclusion: The Saude no Boa intervention was effective at reducing the prevalence of physical inactivity. The possibility of expanding the intervention to other locations should be considered.

Escalas concorrentes para a mensuração da qualidade percebida: uma comparação entre a SERVQUAL e a RSQ

There is no doubt about the importance of service quality as a factor of businesses' success, but to measure this quality has proved to be a challenge when one considers different environmental contexts. Given this, the main goal of this paper was to test two measurement scales of perceived set-vice quality. The comparison between Service Quality scale (Servqual) and Retail Set-vice Quality (RSQ) was conducted by means of a survey with 351 participants, clients of a home center stores chain located in the city of Sao Paulo. The data were analyzed using both exploratory and confirmatory factor analysis. As a result, both scales demonstrated acceptable levels of reliability and validity However; the RSQ demonstrated a better performance in the nomological test since it was able to explain 43% of the loyalty towards the retailer; while the Servqual scale explained only 11%.

Association between neuromuscular tests and kumite performance on the Brazilian Karate National Team

The aim of this study was to verify the relationship of strength and power with performance on an international level karate team during official kumite simulations. Fourteen male black belt karate athletes were submitted to anthropometric data collection and then performed the following tests on two different days: vertical jump test, bench press and squat maximum dynamic strength (1RM) tests. We also tested power production for both exercises at 30 and 60% 1RM and performed a kumite match simulation. Blood samples were obtained at rest and immediately after the kumite matches to measure blood lactate concentration. Karate players were separated by performance (winners vs. defeated) on the kumite matches. We found no significant differences between winners and defeated for strength, vertical jump height, anthropometric data and blood lactate concentration. Interestingly, winners were more powerful in the bench press and squat exercises at 30% 1RM. Maximum strength was correlated with absolute (30% 1RM r = 0.92; 60% 1RM r = 0.63) and relative power (30% 1RM r = 0.74; 60% 1RM r = 0.11, p > 0.05) for the bench press exercise. We concluded that international level karate players' kumite match performance are influenced by higher levels of upper and lower limbs power production.

A positional FEM Formulation for geometrical non-linear analysis of shells

This work presents a fully non-linear finite element formulation for shell analysis comprising linear strain variation along the thickness of the shell and geometrically exact description for curved triangular elements. The developed formulation assumes positions and generalized unconstrained vectors as the variables of the problem, not displacements and finite rotations. The full 3D Saint-Venant-Kirchhoff constitutive relation is adopted and, to avoid locking, the rate of thickness variation enhancement is introduced. As a consequence, the second Piola-Kirchhoff stress tensor and the Green strain measure are employed to derive the specific strain energy potential. Curved triangular elements with cubic approximation are adopted using simple notation. Selected numerical simulations illustrate and confirm the objectivity, accuracy, path independence and applicability of the proposed technique.

Eccentric Hip Muscle Function in Females With and Without Patellofemoral Pain Syndrome

Context: Patellofemoral pain syndrome (PFPS) is a common knee condition in athletes. Recently, researchers have indicated that factors proximal to the knee, including hip muscle weakness and motor control impairment, contribute to the development of PFPS. However, no investigators have evaluated eccentric hip muscle function in people with PFPS. Objective: To compare the eccentric hip muscle function between females with PFPS and a female control group. Design: Cross-sectional study. Setting: Musculoskeletal laboratory. Patients or Other Participants: Two groups of females were studied: a group with PFPS (n = 10) and a group with no history of lower extremity injury or surgery (n = 10). Intervention(s): Eccentric torque of the hip musculature was evaluated on an isokinetic dynamometer. Main Outcome Measure(s): Eccentric hip abduction, adduction, and external and internal rotation peak torque were measured and expressed as a percentage of body mass (Nm/kg x 100). We also evaluated eccentric hip adduction to abduction and internal to external rotation torque ratios. The peak torque value of 5 maximal eccentric contractions was used for calculation. Two-tailed, independent-samples t tests were used to compare torque results between groups. Results: Participants with PFPS exhibited much lower eccentric hip abduction (t(18) = -2.917, P = .008) and adduction (t(18) = -2.764, P =.009) peak torque values than did their healthy counterparts. No differences in eccentric hip external (t(18) = 0.45, P = .96) or internal (t(18) = -0.742, P =.47) rotation peak torque values were detected between the groups. The eccentric hip adduction to abduction torque ratio was much higher in the PFPS group than in the control group (t(18) = 2.113, P = .04), but we found no difference in the eccentric hip internal to external rotation torque ratios between the 2 groups (t(18) = -0.932, P = .36). Conclusions: Participants with PFPS demonstrated lower eccentric hip abduction and adduction peak torque and higher eccentric adduction to abduction torque ratios when compared with control participants. Thus, clinicians should consider eccentric hip abduction strengthening exercises when developing rehabilitation programs for females with PFPS.

Classification of breast masses using a committee machine of artificial neural networks

This work proposes a new approach using a committee machine of artificial neural networks to classify masses found in mammograms as benign or malignant. Three shape factors, three edge-sharpness measures, and 14 texture measures are used for the classification of 20 regions of interest (ROIs) related to malignant tumors and 37 ROIs related to benign masses. A group of multilayer perceptrons (MLPs) is employed as a committee machine of neural network classifiers. The classification results are reached by combining the responses of the individual classifiers. Experiments involving changes in the learning algorithm of the committee machine are conducted. The classification accuracy is evaluated using the area A. under the receiver operating characteristics (ROC) curve. The A, result for the committee machine is compared with the A, results obtained using MLPs and single-layer perceptrons (SLPs), as well as a linear discriminant analysis (LDA) classifier Tests are carried out using the student's t-distribution. The committee machine classifier outperforms the MLP SLP, and LDA classifiers in the following cases: with the shape measure of spiculation index, the A, values of the four methods are, in order 0.93, 0.84, 0.75, and 0.76; and with the edge-sharpness measure of acutance, the values are 0.79, 0.70, 0.69, and 0.74. Although the features with which improvement is obtained with the committee machines are not the same as those that provided the maximal value of A(z) (A(z) = 0.99 with some shape features, with or without the committee machine), they correspond to features that are not critically dependent on the accuracy of the boundaries of the masses, which is an important result.

AVERAGE CONTINUOUS CONTROL OF PIECEWISE DETERMINISTIC MARKOV PROCESSES

This paper deals with the long run average continuous control problem of piecewise deterministic Markov processes (PDMPs) taking values in a general Borel space and with compact action space depending on the state variable. The control variable acts on the jump rate and transition measure of the PDMP, and the running and boundary costs are assumed to be positive but not necessarily bounded. Our first main result is to obtain an optimality equation for the long run average cost in terms of a discrete-time optimality equation related to the embedded Markov chain given by the postjump location of the PDMP. Our second main result guarantees the existence of a feedback measurable selector for the discrete-time optimality equation by establishing a connection between this equation and an integro-differential equation. Our final main result is to obtain some sufficient conditions for the existence of a solution for a discrete-time optimality inequality and an ordinary optimal feedback control for the long run average cost using the so-called vanishing discount approach. Two examples are presented illustrating the possible applications of the results developed in the paper.

FILTERING TECHNIQUES APPLIED ON RAW CARRIER PHASE FOR GPS DETECTING SMALL DYNAMIC DISPLACEMENTS

This work is part of a research under construction since 2000, in which the main objective is to measure small dynamic displacements by using L1 GPS receivers. A very sensible way to detect millimetric periodic displacements is based on the Phase Residual Method (PRM). This method is based on the frequency domain analysis of the phase residuals resulted from the L1 double difference static data processing of two satellites in almost orthogonal elevation angle. In this article, it is proposed to obtain the phase residuals directly from the raw phase observable collected in a short baseline during a limited time span, in lieu of obtaining the residual data file from regular GPS processing programs which not always allow the choice of the aimed satellites. In order to improve the ability to detect millimetric oscillations, two filtering techniques are introduced. One is auto-correlation which reduces the phase noise with random time behavior. The other is the running mean to separate low frequency from the high frequency phase sources. Two trials have been carried out to verify the proposed method and filtering techniques. One simulates a 2.5 millimeter vertical antenna displacement and the second uses the GPS data collected during a bridge load test. The results have shown a good consistency to detect millimetric oscillations.
