Intervenção comunitária para prevenção de acidentes de trânsito entre trabalhadores ciclistas

OBJETIVO: Avaliar uma intervenção educacional de prevenção de acidentes de trânsito com trabalhadores que utilizam a bicicleta como modo de transporte. MÉTODOS: Estudo de intervenção, longitudinal, com implementação escalonada, realizado em cinco bairros com características geográficas distintas na cidade de Pelotas, RS, de janeiro de 2006 a maio de 2007. Foram sorteados 42 setores censitários desses bairros. Todos os domicílios foram visitados em busca de trabalhadores do sexo masculino que utilizassem a bicicleta como modo de transporte, resultando em uma amostra de 1.133 indivíduos. Foram analisados como desfechos "acidentes de trânsito" e de "quase-acidentes". Mensalmente, via telefone, os ciclistas eram questionados a respeito da ocorrência de acidentes de trânsito e de "quase-acidentes". Quinzenalmente, a partir do segundo mês de acompanhamento, um grupo de aproximadamente 60 ciclistas era convidado a participar da intervenção, que incluía um componente educativo (palestra e apresentação de vídeo educativo), distribuição de um kit de segurança (colete noturno refletivo, cartilha educativa e fitas refletivas) e revisão dos freios da bicicleta (manutenção realizada se necessário). Regressão de Poisson, com ajuste para o efeito do tempo, foi utilizada para medir o efeito da intervenção. RESULTADOS: Aproximadamente 45% dos ciclistas não compareceram à intervenção. Durante o período do estudo, 9% dos indivíduos informaram um acidente de trânsito e 88%, um quase-acidente. No total, ocorreram 106 acidentes e 1.091 quase-acidentes. Não foi observado efeito da intervenção em ambos os desfechos. CONCLUSÕES: A intervenção proposta não foi capaz de reduzir acidentes entre trabalhadores ciclistas. Falta de interesse em segurança por parte dos ciclistas e fatores externos, tais como infra-estrutura das vias e comportamento dos motoristas, podem ter colaborado para esse resultado.

Fatores associados à perda funcional em idosos residentes no município de Maceió, Alagoas

OBJETIVO: Identificar fatores associados à perda funcional em idosos residentes na zona urbana. MÉTODOS: Foi realizado estudo de delineamento transversal com amostra populacional de 319 idosos do município de Maceió, AL, em 2009. Para os dados de comprometimento funcional foi utilizada a escala Functional Brazilian Older American Resources and Services Multidimensional Functional Assessment Questionnaire. Foi utilizada análise descritiva, qui-quadrado e análise de regressão para razão de prevalência bruta, sendo o nível de significância adotado de p < 0,05. RESULTADOS: A maioria dos participantes era do sexo feminino (65,8%) e a média de idade foi de 72 anos (dp = 8,83). A prevalência de comprometimento moderado/grave foi de 45,5%, tendo como fatores associados a idade de 75 anos ou mais, até quatro anos de escolaridade, relatar ter duas ou mais doenças crônicas e ser solteiro. CONCLUSÕES: As características dos idosos com comprometimento funcional refletem desigualdades e potenciais impactos desse segmento populacional sobre os serviços de saúde.

Sustainability reporting and financial reporting: the relevance of an integrated reporting approach

In the business world, there are issues such as globalisation, environmental awareness, and the rising expectations of public opinion which have a specific role in what is required from companies as providers of information to the market. This chapter refers to the current state of corporate reporting (financial reporting and sustainability reporting) and demonstrates the need for evolution to a more integrated method of reporting which meets the stakeholders’ needs. This research offers a reflection on how this development can be achieved, which notes the ongoing efforts by international organisations in implementing the diffusion and adoption, as well as looking at the characteristics which are needed for this type of reporting. It also makes the link between an actual case of a company that is one of the world references in sustainable development and integrated reporting. Whether or not the integrated reporting is the natural evolution of the history of financial and sustainability reporting, it still cannot yet claim to be infallible. However, it may definitely be concluded that a new approach is necessary to meet the needs which are continuously developing for a network of stakeholders.

Prevalência de tracoma entre escolares brasileiros

OBJETIVO: Estimar a prevalência e descrever a distribuição do tracoma entre escolares em municípios brasileiros.MÉTODOS: Estudo de corte transversal, usando amostragem por conglomerados, da população escolar dos municípios brasileiros com Índice de Desenvolvimento Humano-Municipal menor que a média nacional. O inquérito de prevalência de tracoma foi realizado pelo Ministério da Saúde entre 2002 e 2007. Foram selecionados 119.531 alunos de 2.270 escolas localizadas em 1.156 municípios. Os alunos foram submetidos ao exame ocular externo, com lupa (2,5X), para detecção de sinais clínicos de tracoma segundo critérios da OMS. Estimou-se a prevalência de tracoma segundo estado e em nível nacional, e seus respectivos intervalos de 95% de confiança. Para a comparação de variáveis categóricas foram usados os testes do Qui-quadrado e do Qui-quadrado de tendência linear.RESULTADOS: Foram detectados 6.030 casos de tracoma, resultando em prevalência de 5,0% (IC95% 4,5;5,4). Não foi encontrada diferença significante entre os sexos. A prevalência de tracoma foi de 8,2% entre menores de cinco anos de idade, diminuindo nas faixas etárias mais altas (p < 0,01). Houve diferença significante entre as prevalências de tracoma na zona urbana e rural, 4,3% versus 6,2%, respectivamente (p < 0,01). Foram detectados casos em 901 municípios (77,7% da amostra), em todas as regiões do País. Em 36,8% dos municípios selecionados a prevalência foi superior a 5%.CONCLUSÕES: O estudo mostra que o tracoma é um importante problema de saúde pública no Brasil, contradizendo a crença de que a endemia estaria controlada no País. O inquérito realizado apresenta uma linha de base para avaliação das intervenções planejadas com vistas ao alcance da meta mundial de certificação da eliminação do tracoma como causa de cegueira no Brasil, até 2020.

Tracking of physical activity during adolescence: the 1993 Pelotas Birth Cohort, Brazil

OBJECTIVE To analyze physical activity during adolescence in participants of the 1993 Pelotas Birth Cohort Study, Brazil. METHODS Data on leisure time physical activity at 11, 15, and 18 years of age were analyzed. At each visit, a cut-off point of 300 min/week was used to classify adolescents as active or inactive. A total of 3,736 participants provided data on physical activity at each of the three age points. RESULTS A significant decline in the proportion of active adolescents was observed from 11 to 18 years of age, particularly among girls (from 32.9% to 21.7%). The proportions of girls and boys who were active at all three age points were 28.0% and 55.1%, respectively. After adjustment for sex, economic status, and skin color, participants who were active at 11 and 15 years of age were 58.0% more likely to be active at 18 years of age compared with those who were inactive at 11 and 15 years of age. CONCLUSIONS Physical activity declined during adolescence and inactivity tended to track over time. Our findings reinforce the need to promote physical activity at early stages of life, because active behavior established early tends to be maintained over time.

The 1853-1856 cholera morbus epidemic in Portugal as seen by the press

This research is part of a larger project focused on producing a History of the Popularization of Science and Technology in Portugal. The goal is to find out how scientific knowledge reached the common people in the nineteenth century, using newspapers as the main source of information. Keeping in mind the population’s limited access to written material, nevertheless each newspaper could be read daily by an estimate 30.000 people in Lisbon, which places this source as probably the most widespread vehicle to divulge the latest scientific news at the time to an unspecialised audience. With a cholera morbus epidemic which affected the second largest Portuguese town and all the northern regions, as well as the Algarve, news and reports on its evolution were considered essential. A large database was built in order to analyse the news concerning this disease in 1855 and 1856, especially the ones about prevention and treatment. These are important historical sources that give us real information on the scientific knowledge of the time and the way it was used by society.

RENAL HISTOPATHOLOGICAL FINDINGS IN DOGS WITH VISCERAL LEISHMANIASIS

Visceral leishmaniasis affects various organs including the kidneys; which can lead to renal failure and death. In order to verify this renal involvement, material was evaluated from 100 dogs naturally infected and with serological diagnosis of canine visceral leishmaniasis (CVL). Inflammatory changes were present in 25.3% of the tubules, in 67.0% of interstitium and in 52.0% of glomeruli. There was no significant difference (p > 0.05) between the presence of glomerulonephritis in symptomatic and oligosymptomatic dogs. The membranous and membranoproliferative glomerulonephritis were the most frequent, both with 18.0% frequency, followed by focal segmental glomerulosclerosis with 14.0%. Changes such as cylindruria, tubular and fibrosis hypertrophy, periglomerular inflammatory infiltrate, and multifocal and diffuse peritubular inflammatory infiltrate were observed. The findings are consistent with those of other authors indicating that renal involvement is common in CVL and the standards of membranous and membranoploriferative glomerulonephritis, as well as the tubulointerstitial involvement, are frequent.

Delineating environmental groundwater vulnerability and protection zones mapping in fractured rock masses

Hard‐rock watersheds commonly exhibit complex geological bedrock and morphological features. Hydromineral resources have relevant economic value for the thermal spas industry. The present study aims to develop a groundwater vulnerability approach in Caldas da Cavaca hydromineral system (Aguiar da Beira, Central Portugal) which has a thermal tradition that dates back to the late 19th century, and contribute to a better understanding of the hydrogeological conceptual site model. In this work different layers were overlaid, generating several thematic maps to arrive at an integrated framework of several key‐sectors in Caldas da Cavaca site. Thus, to accomplish a comprehensive analysis and conceptualization of the site, a multi‐technical approach was used, such as, field and laboratory techniques, where several data was collected, like geotectonics, hydrology and hydrogeology, hydrogeomorphology, hydrogeophysical and hydrogeomechanical zoning aiming the application of the so‐called DISCO method. All these techniques were successfully performed and a groundwater vulnerability to contamination assessment, based on GOD‐S, DRASTIC‐Fm, SINTACS, SI and DISCO indexes methodology, was delineated. Geographical Information Systems (GIS) technology was on the basis to organise and integrate the geodatabases and to produce all the thematic maps. This multi‐technical approach highlights the importance of groundwater vulnerability to contamination mapping as a tool to support hydrogeological conceptualisation, contributing to better decision‐making of water resources management and sustainability.

EFFECT OF HIGHLY ACTIVE ANTIRETROVIRAL THERAPY ON VAGINAL Candida spp. ISOLATION IN HIV-INFECTED COMPARED TO HIV-UNINFECTED WOMEN

 Vulvovaginal candidiasis (VVC) in HIV-infected women contributed to the impairment of their quality of life. The aim of this study was to evaluate the effect of highly active antiretroviral therapy (HAART) use on the vaginal Candida spp. isolation in HIV-infected compared to HIV-uninfected women. This cross-sectional study included 178 HIV-infected (HIV group) and 200 HIV-uninfected women (control) that were studied at the Specialized Assistance Service (SAE) for sexually transmitted diseases (STD)/AIDS of the city of Maringá, Brazil, from April 1 to October 30, 2011. The yeasts were isolated and identified by phenotypic and molecular methods. The in vitro antifungal susceptibility to fluconazole, itraconazole, nystatin and amphotericin B was tested by the reference microdilution method. Higher frequencies of total vaginal Candida spp. isolation were found in the HIV-infected group than in the control group. However, both groups showed a similar frequency of colonization and VVC. Although C. albicans was the most frequent and sensitive to azolics and polyenes in both HIV-infected and uninfected women, the emerging resistance of C. glabrata to amphotericin B in the HIV-infected women was observed. Although higher frequency of vaginal Candida spp. isolation had been observed in the HIV-infected than in HIV-uninfected women, colonization and VVC showed similar frequency in both groups, indicating that HAART appears to protect against vaginal colonization and VVC.
