Avaliação da exposição a fungos e partículas em explorações avícolas e suinícolas: estudo

O projeto “Avaliação da Exposição a Fungos e Partículas em Explorações Avícolas e Suinícolas” contemplou um elevado número de colheitas ambientais e biológicas e respectivo processamento laboratorial, sendo apenas possível a sua concretização graças ao financiamento disponibilizado pela Autoridade para as Condições de Trabalho. Foi realizado um estudo transversal para avaliar a contaminação causada por fungos e partículas em 7 explorações avícolas e 7 explorações suinícolas. No que concerne à monitorização biológica, foram medidos os parâmetros espirométricos, utilizando o espirómetro MK8 Microlab, avaliada a existência de sintomas clínicos associados com a asma e outras doenças alérgicas, através de questionário adaptado European Community Respiratory Health Survey e, ainda, avaliada a sensibilização aos agentes fúngicos (IgE). Foram ainda adicionados dois objetivos ao estudo, designadamente: aferir a existência de três espécies/estirpes potencialmente patogénicas/toxinogénicas com recurso à biologia molecular e avaliar a exposição dos trabalhadores à micotoxina aflatoxina B1 por recurso a indicador biológico de exposição. Foram colhidas 27 amostras de ar de 25 litros nas explorações avícolas e 56 de 50 litros nas explorações suinícolas através do método de impacto. As colheitas de ar e a medição da concentração das partículas foram realizadas no interior e no exterior dos pavilhões, sendo este último considerado como local de referência. Simultaneamente, a temperatura e a humidade relativa também foram registadas. As colheitas das superfícies foram realizadas através da técnica de zaragatoa, tendo sido utilizado um quadrado de metal inoxidável de 10 cm de lado, de acordo com a International Standard ISO 18593 – 2004. As zaragatoas obtidas (20 das explorações avícolas e 48 das explorações suinícolas) foram inoculadas em malte de extract agar (2%) com cloranfenicol (0,05 g/L). Além das colheitas de ar e de superfícies, foram também obtidas colheitas da cama das explorações avícolas (7 novas e 14 usadas) e da cobertura do pavimento das explorações suinícolas (3 novas e 4 usadas) e embaladas em sacos esterilizados. Cada amostra foi diluída e inoculada em placas contendo malte extract agar. Todas as amostras foram incubadas a 27,5ºC durante 5 a 7 dias e obtidos resultados quantitativos (UFC/m3; UFC/m2; UFC/g) e qualitativos com a identificação das espécies fúngicas. Para a aplicação dos métodos de biologia molecular foram realizadas colheitas de ar de 300 litros utilizando o método de impinger com a velocidade de recolha de 300 L/min. A identificação molecular de três espécies potencialmente patogénicas e/ou toxinogénicas (Aspergillus flavus, Aspergillus fumigatus e Stachybotrys chartarum) foram obtidas por PCR em tempo real (PCR TR) utilizando o Rotor-Gene 6000 qPCR Detection System. As medições de partículas foram realizadas por recurso a equipamento de leitura direta (modelo Lighthouse, 2016 IAQ). Este recurso permitiu medir a concentração (mg/m3) de partículas em 5 dimensões distintas (PM 0.5; PM 1.0; PM 2.5; PM 5.0; PM10). Nas explorações avícolas, 28 espécies/géneros de fungos foram isolados no ar, tendo Aspergillus versicolor sido a espécie mais frequente (20.9%), seguida por Scopulariopsis brevicaulis (17.0%) e Penicillium sp. (14.1%). Entre o género Aspergillus, Aspergillus flavus apresentou o maior número de esporos (>2000 UFC/m3). Em relação às superfícies, A. versicolor foi detetada em maior número (>3 × 10−2 UFC/m2). Na cama nova, Penicillium foi o género mais frequente (59,9%), seguido por Alternaria (17,8%), Cladosporium (7,1%) e Aspergillus (5,7%). Na cama usada, Penicillium sp. foi o mais frequente (42,3%), seguido por Scopulariopsis sp. (38,3%), Trichosporon sp. (8,8%) e Aspergillus sp. (5,5%). Em relação à contaminação por partículas, as partículas com maior dimensão foram detectadas em maiores concentrações, designadamente as PM5.0 (partículas com a dimensão de 5.0 bm ou menos) e PM10 (partículas com a dimensão de 10 bm ou menos). Neste setting a prevalência da alteração ventilatória obstrutiva foi superior nos indivíduos com maior tempo de exposição (31,7%) independentemente de serem fumadores (17,1%) ou não fumadores (14,6%). Relativamente à avaliação do IgE específico, foi apenas realizado em trabalhadores das explorações avícolas (14 mulheres e 33 homens), não tendo sido encontrada associação positiva (p<0.05%) entre a contaminação fúngica e a sensibilização a antigénios fúngicos. No caso das explorações suinícolas, Aspergillus versicolor foi a espécie mais frequente (20,9%), seguida por Scopulariopsis brevicaulis (17,0%) e Penicillium sp. (14,1%). No género Aspergillus, A. versicolor apresentou o maior isolamento no ar (>2000 UFC/m3) e a maior prevalência (41,9%), seguida por A. flavus e A. fumigatus (8,1%). Em relação às superfícies analisadas, A. versicolor foi detetada em maior número (>3 ×10−2 UFC/m2). No caso da cobertura do pavimento das explorações suinícolas, o género Thicoderma foi o mais frequente na cobertura nova (28,0%) seguida por A. versicolor e Acremonium sp. (14,0%). O género Mucor foi o mais frequente na cobertura usada (25,1%), seguido por Trichoderma sp. (18,3%) e Acremonium sp. (11,2%). Relativamente às partículas, foram evidenciados também valores mais elevados na dimensão PM5 e, predominantes nas PM10. Neste contexto, apenas 4 participantes (22,2%) apresentaram uma alteração ventilatória obstrutiva. Destes, as obstruções mais graves encontraram-se nos que também apresentavam maior tempo de exposição. A prevalência de asma na amostra de trabalhadores em estudo, pertencentes aos 2 contextos em estudo, foi de 8,75%, tendo-se verificado também uma prevalência elevada de sintomatologia respiratória em profissionais não asmáticos. Em relação à utilização complementar dos métodos convencionais e moleculares, é recomendável que a avaliação da contaminação fúngica nestes settings, e, consequentemente, a exposição profissional a fungos, seja suportada pelas duas metodologias e, ainda, que ocorre exposição ocupacional à micotoxina aflatoxina B1 em ambos os contextos profissionais. Face aos resultados obtidos, é importante salientar que os settings alvo de estudo carecem de uma intervenção integrada em Saúde Ocupacional no âmbito da vigilância ambiental e da vigilância da saúde, com o objetivo de diminuir a exposição aos dois factores de risco estudados (fungos e partículas).

A behavioral intervention in a cohort of Japanese-Brazilians at high cardiometabolic risk

OBJECTIVE: To assess the effect of a health promotion program on cardiometabolic risk profile in Japanese-Brazilians. METHODS: A total of 466 subjects from a study on diabetes prevalence conducted in the city of Bauru, southeastern Brazil, in 2000 completed a 1-year intervention program (2005-2006) based on healthy diet counseling and physical activity. Changes in blood pressure and metabolic parameters in the 2005-2006 period were compared with annual changes in these same variables in the 2000-2005 period. RESULTS: During the intervention, there were greater annual reductions in mean (SD) waist circumference [-0.5(3.8) vs. 1.2(1.2) cm per year, p<0.001], systolic blood pressure [-4.6(17.9) vs. 1.8(4.3) mmHg per year, p<0.001], 2-hour plasma glucose [-1.2(2.1) vs. -0.2(0.6) mmol/L per year, p<0.001], LDL-cholesterol [-0.3(0.9) vs. -0.1(0.2) mmol/L per year, p<0.001] and Framingham coronary heart disease risk score [-0.25(3.03) vs. 0.11(0.66) per year, p=0.02] but not in triglycerides [0.2(1.6) vs. 0.1(0.42) mmol/L per year, p<0.001], and fasting insulin level [1.2(5.8) vs. -0.7(2.2) IU/mL per year, p<0.001] compared with the pre-intervention period. Significant reductions in the prevalence of impaired fasting glucose/impaired glucose tolerance and diabetes were seen during the intervention (from 58.4% to 35.4%, p<0.001; and from 30.1% to 21.7%, p= 0.004, respectively). CONCLUSIONS: A one-year community-based health promotion program brings cardiometabolic benefits in a high-risk population of Japanese-Brazilians.

Risk criteria in occupational environments: critical overview and discussion

The current work can be seen as a starting point for the discussion of the problematic on risk acceptance criteria in occupational environments. Some obstacles to the quantitative acceptance criteria formulation and use were analyzed. A look to the long tradition of major hazards accidents was also performed. This work shows that organizations can have several difficulties in acceptance criteria formulation and that the use of pre-defined acceptance criteria in risk assessment methodologies can be inadequate in some cases. It is urgent to define guidelines that can help organizations in the formulation of risk acceptance criteria for occupational environments.

Legal and political regulation of higher education in Portugal: an evolutionary perspective on the current policy issues and the problem of order

The higher education system in Europe is currently under stress and the debates over its reform and future are gaining momentum. Now that, for most countries, we are in a time for change, in the overall society and the whole education system, the legal and political dimensions have gained prominence, which has not been followed by a more integrative approach of the problem of order, its reform and the issue of regulation, beyond the typical static and classical cost-benefit analyses. The two classical approaches for studying (and for designing the policy measures of) the problem of the reform of the higher education system - the cost-benefit analysis and the legal scholarship description - have to be integrated. This is the argument of our paper that the very integration of economic and legal approaches, what Warren Samuels called the legal-economic nexus, is meaningful and necessary, especially if we want to address the problem of order (as formulated by Joseph Spengler) and the overall regulation of the system. On the one hand, and without neglecting the interest and insights gained from the cost-benefit analysis, or other approaches of value for money assessment, we will focus our study on the legal, social and political aspects of the regulation of the higher education system and its reform in Portugal. On the other hand, the economic and financial problems have to be taken into account, but in a more inclusive way with regard to the indirect and other socio-economic costs not contemplated in traditional or standard assessments of policies for the tertiary education sector. In the first section of the paper, we will discuss the theoretical and conceptual underpinning of our analysis, focusing on the evolutionary approach, the role of critical institutions, the legal-economic nexus and the problem of order. All these elements are related to the institutional tradition, from Veblen and Commons to Spengler and Samuels. The second section states the problem of regulation in the higher education system and the issue of policy formulation for tackling the problem. The current situation is clearly one of crisis with the expansion of the cohorts of young students coming to an end and the recurrent scandals in private institutions. In the last decade, after a protracted period of extension or expansion of the system, i. e., the continuous growth of students, universities and other institutions are competing harder to gain students and have seen their financial situation at risk. It seems that we are entering a period of radical uncertainty, higher competition and a new configuration that is slowly building up is the growth in intensity, which means upgrading the quality of the higher learning and getting more involvement in vocational training and life-long learning. With this change, and along with other deep ones in the Portuguese society and economy, the current regulation has shown signs of maladjustment. The third section consists of our conclusions on the current issue of regulation and policy challenge. First, we underline the importance of an evolutionary approach to a process of change that is essentially dynamic. A special attention will be given to the issues related to an evolutionary construe of policy analysis and formulation. Second, the integration of law and economics, through the notion of legal economic nexus, allows us to better define the issues of regulation and the concrete problems that the universities are facing. One aspect is the instability of the political measures regarding the public administration and on which the higher education system depends financially, legally and institutionally, to say the least. A corollary is the lack of clear strategy in the policy reforms. Third, our research criticizes several studies, such as the one made by the OECD in late 2006 for the Ministry of Science, Technology and Higher Education, for being too static and neglecting fundamental aspects of regulation such as the logic of actors, groups and organizations who are major players in the system. Finally, simply changing the legal rules will not necessary per se change the behaviors that the authorities want to change. By this, we mean that it is not only remiss of the policy maker to ignore some of the critical issues of regulation, namely the continuous non-respect by academic management and administrative bodies of universities of the legal rules that were once promulgated. Changing the rules does not change the problem, especially without the necessary debates form the different relevant quarters that make up the higher education system. The issues of social interaction remain as intact. Our treatment of the matter will be organized in the following way. In the first section, the theoretical principles are developed in order to be able to study more adequately the higher education transformation with a modest evolutionary theory and a legal and economic nexus of the interactions of the system and the policy challenges. After describing, in the second section, the recent evolution and current working of the higher education in Portugal, we will analyze the legal framework and the current regulatory practices and problems in light of the theoretical framework adopted. We will end with some conclusions on the current problems of regulation and the policy measures that are discusses in recent years.

Risk perception about zoonoses in immigrants and Italian workers in Northwestern Italy

OBJETIVO: To assess factors associated with a low risk perception of zoonoses and to identify the gaps in knowledge about transmission and prevention of zoonoses in immigrant and Italian workers. MÉTODOS: A cross-sectional study with 175 workers in the agro-livestock and agro-food industry in Piemonte, Italy, was carried out. Data were collected with a semi-structured questionnaire based on knowledge, attitudes and practices (KAP) survey. We calculated proportions and used chi-square tests and odds ratios to assess associations. Eight individual interviews with key informants on immigration and public health in Piemonte were carried out. RESULTADOS: Participants were 82 (47%) Italians and 93 (53%) immigrants. Immigrants were from Romania, Morocco, Albania, India, China, Argentina, Peru, Macedonia, Ivory Coast, Ukraine and Colombia. The study revealed significant differences in risk perception at work (p = 0.001). We found associations between "not having correct knowledge about zoonoses" and the following variables: i. "being immigrant" OR = 4.1 (95%CI 1.7;9.8 p ≤ 0.01); ii. "working in the livestock industry" OR = 2.9 (95%CI 1.2;15.4 p = 0.01); and iii. "being an unqualified worker" OR = 4.4 (95%CI 2.9;15.4 p ≤ 0.01). Another strong association was found between being immigrant and having a low job qualification OR = 6.7 (IC95% 2.9 - 15.4 p ≤ 0.01). Asian immigrants were the group with the highest frequency of risky behaviours and the lowest level of knowledge about zoonoses. CONCLUSÕES: Our results indicate that there were differences in risk perception of zoonoses between the groups participating in our study. These results suggest that immigrant status can be considered a risk factor for having lower risk perception and lower level of knowledge of zoonoses at work. There is a relationship between this specific knowledge of zoonoses and lack of training and instruction among migrant populations. Our results stress the need for developing education programs on zoonoses prevention among the immigrant population in Piemonte, Italy.

As guardas de segurança para proteção a motociclistas: características e graus de eficácia

Os acidentes envolvendo veículos de duas rodas, são um dos maiores problemas da segurança rodoviária atual, no âmbito Europeu. Um dos tipos de acidentes que pode causar danos mais graves aos ocupantes desses veículos é o embate com guardas de segurança. Em consequência disso, neste trabalho foram desenvolvidas opiniões, abonatórias ou não, ao uso de dispositivos de proteção para motociclistas acoplados nas guardas de segurança. Estas opiniões vão partir de dados estatísticos, de estudos e exemplos concretos de vários autores e publicações relacionados com esta temática, sendo que o tipo de dispositivo de proteção para motociclistas que vai estar mais em foco e sendo ele o mais habitual nas estradas portuguesas será a saia metálica. Estes dispositivos de segurança para motociclistas ainda não são de uso obrigatório nas guardas de segurança na maioria dos países do continente Europeu, segundo a norma europeia EN 1317, apesar deste tipo de proteção já estar normalizada segundo padrões de lesões biomecânicos na zona da cabeça, cervical e anca/abdómen descritos na norma EN 1317 UNE 135900 – 1:2003, em alguns países é descurado o uso destas proteções, por não serem obrigatórias e porque ainda se tornam mais dispendiosas que as guardas de segurança habituais (barreiras de metal simples). Este estudo serviu essencialmente para verificar se estes dispositivos salvaguardam ou não a vida dos utilizadores de duas rodas, pois, se pelo contrário, aumentam ainda o risco, ou de lesões mais gravosas ou mesmo de morte, aquando o embate com as mesmas, os gastos associados a este tipo de equipamentos serão totalmente inúteis e desnecessários.

Optimising protocol of acquisition and post-processing procedures in the assessment of coronary artery disease by computed tomography

Coronary artery disease (CAD) is currently one of the most prevalent diseases in the world population and calcium deposits in coronary arteries are one direct risk factor. These can be assessed by the calcium score (CS) application, available via a computed tomography (CT) scan, which gives an accurate indication of the development of the disease. However, the ionising radiation applied to patients is high. This study aimed to optimise the protocol acquisition in order to reduce the radiation dose and explain the flow of procedures to quantify CAD. The main differences in the clinical results, when automated or semiautomated post-processing is used, will be shown, and the epidemiology, imaging, risk factors and prognosis of the disease described. The software steps and the values that allow the risk of developingCADto be predicted will be presented. A64-row multidetector CT scan with dual source and two phantoms (pig hearts) were used to demonstrate the advantages and disadvantages of the Agatston method. The tube energy was balanced. Two measurements were obtained in each of the three experimental protocols (64, 128, 256 mAs). Considerable changes appeared between the values of CS relating to the protocol variation. The predefined standard protocol provided the lowest dose of radiation (0.43 mGy). This study found that the variation in the radiation dose between protocols, taking into consideration the dose control systems attached to the CT equipment and image quality, was not sufficient to justify changing the default protocol provided by the manufacturer.

Is adolescent pregnancy a risk factor for low birth weight?

OBJECTIVE: The objective of this study was to evaluate whether adolescent pregnancy is a risk factor for low birth weight (LBW) babies. METHODS: This was a cross-sectional study of mothers and their newborns from a birth cohort in Aracaju, Northeastern Brazil. Data were collected consecutively from March to July 2005. Information collected included socioeconomic, biological and reproductive aspects of the mothers, using a standardized questionnaire. The impact of early pregnancy on birth weight was evaluated by multiple logistic regression. RESULTS: We studied 4,746 pairs of mothers and their babies. Of these, 20.6% were adolescents (< 20 years of age). Adolescent mothers had worse socioeconomic and reproductive conditions and perinatal outcomes when compared to other age groups. Having no prenatal care and smoking during pregnancy were the risk factors associated with low birth weight. Adolescent pregnancy, when linked to marital status "without partner", was associated with an increased proportion of low birth weight babies. CONCLUSIONS: Adolescence was a risk factor for LBW only for mothers without partners. Smoking during pregnancy and lack of prenatal care were considered to be independent risk factors for LBW.

Risk factors of HIV-related oral lesions in adults

OBJECTIVE: To assess the risk factors in the occurrence of oral lesions in HIV-positive adults. METHODS: A retrospective analytical-descriptive survey was conducted using the medical/dental records of 534 patients with oral lesions associated with HIV. The data were collected from five referral centers for managing HIV and associated comorbidities in the city of Porto Alegre, Southern Brazil, between 1996 and 2011. Using a standardized form, socio-demographic and clinical data were recorded. Exclusively and definitively diagnosed oral pathologies were included and classified according to ECC criteria on Oral Problems Related to HIV Infection. For data analysis cross-tabulations, Chi-squared tests and logistic regression models were used where appropriate. RESULTS: CD4+ counts lower than 350 cells/mm³ (p < 0.001), alcohol consumption (p = 0.011) and female gender (p = 0.031) were predisposing factors for oral candidiasis. The occurrence of hairy leukoplakia was independently associated with CD4+ counts below 500 cells/mm³, (p = 0.029) a viral load above 5,000 copies/mm³ (p = 0.003) and smoking (p = 0.005). CONCLUSIONS: Moderate and severe degrees of immunodeficiency and detectable viral loads were risk factors for the onset of oral lesions. Smoking and alcohol consumption also increased susceptibility to the development of opportunistic infections in HIV-positive adults from Porto Alegre, irrespective of the use of antiretroviral therapy.

Human risk assessment of benzene after a gasoline station fuel leak

OBJECTIVE: To assess the health risk of exposure to benzene for a community affected by a fuel leak. METHODS: Data regarding the fuel leak accident with, which occurred in the Brasilia, Federal District, were obtained from the Fuel Distributor reports provided to the environmental authority. Information about the affected population (22 individuals) was obtained from focal groups of eight individuals. Length of exposure and water benzene concentration were estimated through a groundwater flow model associated with a benzene propagation model. The risk assessment was conducted according to the Agency for Toxic Substances and Disease Registry methodology. RESULTS: A high risk perception related to the health consequences of the accident was evident in the affected community (22 individuals), probably due to the lack of assistance and a poor risk communication from government authorities and the polluting agent. The community had been exposed to unsafe levels of benzene (> 5 µg/L) since December 2001, five months before they reported the leak. The mean benzene level in drinking water (72.2 µg/L) was higher than that obtained by the Fuel Distributer using the Risk Based Corrective Action methodology (17.2 µg/L).The estimated benzene intake from the consumption of water and food reached a maximum of 0.0091 µg/kg bw/day (5 x 10-7 cancer risk per 106 individuals). The level of benzene in water vapor while showering reached 7.5 µg/m3 for children (1 per 104 cancer risk). Total cancer risk ranged from 110 to 200 per 106 individuals. CONCLUSIONS: The population affected by the fuel leak was exposed to benzene levels that might have represented a health risk. Local government authorities need to develop better strategies to respond rapidly to these types of accidents to protect the health of the affected population and the environment.

Effects of irregular-shift work and physical activity on cardiovascular risk factors in truck drivers

OBJECTIVE: To analyze the putative effect of type of shift and its interaction with leisure-time physical activity on cardiovascular risk factors in truck drivers.METHODS: A cross-sectional study was undertaken on 57 male truck drivers working at a transportation company, of whom 31 worked irregular shifts and 26 worked on the day-shift. Participants recorded their physical activity using the International Physical Activity Questionnaire along with measurements of blood pressure, body mass index and waist-hip ratio. Participants also provided a fasting blood sample for analysis of lipid-related outcomes. Data were analyzed using a factorial model which was covariate-controlled for age, smoking, work demand, control at work and social support.RESULTS: Most of the irregular-shift and day-shift workers worked more than 8 hours per day (67.7% and 73.1%, respectively). The mean duration of experience working the irregular schedule was 15.7 years. Day-shift workers had never engaged in irregular-shift work and had been working as a truck driver for 10.8 years on average. The irregular-shift drivers had lower work demand but less control compared to day-shift drivers (p < 0.05). Moderately-active irregular-shift workers had higher systolic and diastolic arterial pressures (143.7 and 93.2 mmHg, respectively) than moderately-active day-shift workers (116 and 73.3 mmHg, respectively) (p < 0.05) as well as higher total cholesterol concentrations (232.1 and 145 mg/dl, respectively) (p = 0.01). Irrespective of their physical activity, irregular-shift drivers had higher total cholesterol and LDL-cholesterol concentrations (211.8 and 135.7 mg/dl, respectively) than day-shift workers (161.9 and 96.7 mg/dl, respectively (ANCOVA, p < 0.05).CONCLUSIONS: Truck drivers are exposed to cardiovascular risk factors due to the characteristics of the job, such as high work demand, long working hours and time in this profession, regardless of shift type or leisure-time physical activity.

Prevalence and determinants of child undernutrition and stunting in semiarid region of Brazil

OBJECTIVE : To analyze the evolution in the prevalence and determinants of malnutrition in children in the semiarid region of Brazil. METHODS : Data were collected from two cross-sectional population-based household surveys that used the same methodology. Clustering sampling was used to collect data from 8,000 families in Ceará, Northeastern Brazil, for the years 1987 and 2007. Acute undernutrition was calculated as weight/age < -2 standard deviation (SD); stunting as height/age < -2 SD; wasting as weight/height < -2 SD. Data on biological and sociodemographic determinants were analyzed using hierarchical multivariate analyses based on a theoretical model. RESULTS : A sample of 4,513 and 1,533 children under three years of age, in 1987 and 2007, respectively, were included in the analyses. The prevalence of acute malnutrition was reduced by 60.0%, from 12.6% in 1987 to 4.7% in 2007, while prevalence of stunting was reduced by 50.0%, from 27.0% in 1987 to 13.0% in 2007. Prevalence of wasting changed little in the period. In 1987, socioeconomic and biological characteristics (family income, mother’s education, toilet and tap water availability, children’s medical consultation and hospitalization, age, sex and birth weight) were significantly associated with undernutrition, stunting and wasting. In 2007, the determinants of malnutrition were restricted to biological characteristics (age, sex and birth weight). Only one socioeconomic characteristic, toilet availability, remained associated with stunting. CONCLUSIONS : Socioeconomic development, along with health interventions, may have contributed to improvements in children’s nutritional status. Birth weight, especially extremely low weight (< 1,500 g), appears as the most important risk factor for early childhood malnutrition.
