O estudo avalia a implantação do Centro de Referência Regional em Saúde do Trabalhador da Região Oeste do estado do Rio Grande do Sul (Cerest Oeste), mediante o diagnóstico do perfil ocupacional e de saúde do trabalhador em Alegrete, e propõe estratégias para viabilizar este processo e subsidiar o seu planejamento. Desenvolveu-se um estudo retrospectivo com base em análise quantitativa de dados secundários de bancos institucionais, referentes ao período de 2000 a 2009, e análise qualitativa por meio de entrevistas semiestruturadas com informantes-chave envolvidos no processo de implantação do Cerest. Evidenciou-se que a principal barreira na implantação foi a falta de articulação entre as diferentes esferas de gestão. Isso dificultou a definição de responsabilidades que dessem conta do caráter regional do Centro e implicou em problemas de infraestrutura e recursos humanos. A definição precoce da equipe e o envolvimento do controle social desde a fase de projeto podem auxiliar no enfrentamento das dificuldades. Faz-se necessário também ampliar as informações epidemiológicas em saúde do trabalhador e facilitar o acesso a elas de forma a instrumentalizar o planejamento das ações do Centro.
Fique fibers, native to Colombia, are traditionally used for ropes and bags. In the extraction of long fibers for these purposes, the same amount of short fibers is generated; the short fibers are then discarded in the soil or in landfills. This agro-industrial waste is cellulose-rich and can be potentially developed into new biobased products. As an alternative use for these fibers, viscose regenerated fibers with potential applications in the textile industry were developed. Fique waste fibers were pulped (to produce fique cellulose pulp, FCP) using a 33 design of experiment (DOE) to adjust the variables of the whitening treatment, and DOE analysis showed that time and hydrogen peroxide concentration do not have a significant effect on non-cellulosic remotion, unlike temperature. The behavior of this pulp in the production of viscose was compared against that of commercially available wood cellulose pulp (WCP). FCP showed a suitable cellulose content with a high degree of polymerization, which makes it a viable pulp for producing discontinuous viscose rayon filaments. Both pulps showed the same performance in the production of the viscose dope and the same chemical, thermal, and mechanical behavior after being regenerated.
This study assessed the effects of intrauterine growth restriction and risk factors for intrauterine growth restriction on blood lipids in adoles-
Results Semen assessments were obtained for 502 men. This group was representative of the general population regarding social class, education and geography. The median sperm concentration of samples was 48310 6 /ml, but after adjustment to a mean abstinence of 4 days, 64310 6 /ml. In these adjusted data, "low" sperm counts (below 20310 6 /ml) were found in 18% of men (95% CI 15% to 21%). However, the prevalence of "low" sperm counts showed no trend across the 10-year range of birth years. Conclusion This first report of sperm concentration in a random sample of a general population shows that nearly a fifth of men had poor semen quality. Further work is required to clarify the fertility relevance of a single low sperm concentration when there is no imposition of abstinence prior to sample, and to understand cause of the fertility deficit found in many survey participants. Background Environmental toxic metal exposure may adversely affect children's development and behaviour. Data are lacking about heavy metal exposure in children in UAE and Gulf countries. Objectives To determine blood concentrations of 12 heavy metals in school-age children in Al Ain City, UAE. Methods It was a cross sectional study. One hundred and forty seven subjects were selected from nine elementary schools. The mean age was 8.4 years (SD 62 years). ICP-MS instrument was used to determine the metal concentration. Data analysis was performed using the SPSS. Results The (mean6SD) blood level for study children (n¼146) of lead was 25.86613.06 ppb, cadmium 0.3160.25 ppb, arsenic 10.7464.71 ppb, mercury 1.3961.16 ppb, manganese 1.8561.09 ppb, nickel 9.1868.23 ppb, zinc 373161752 ppb, chromium 2.1061.53 ppb, cobalt 0.6560.40 ppb, copper 10646403 ppb, molybdenum 1.5961.25 ppb, and antinomy 0.6060.63 ppb. SP4-26 BURDEN OF TOXIC METAL EXPOSURE AMONG SCHOOL-AGED CHILDREN IN UNITED ARAB EMIRATESConclusions Reference values for the trace metals vary markedly; especially due to sampling, age, diet, exposure differences and analytical techniques used. In this study, the mean blood lead was below the CDC's recommended level of concern (>10 mg/dl) and with cadmium, mercury and chromium were comparable with similar studies elsewhere; manganese and zinc were slightly lower; copper and molybdenum were slightly higher while arsenic and cobalt much higher. Blood screening and surveillance linked to appropriate public health interventions is strongly recommended for UAE.
The issue of "access" is central to epidemiological research. Once a set of "interesting" data has been targeted, the researcher must overcome the ethical, legal and other conditions to actually access the data and samples of interest. In addition, study specific conditions (eg, access to aggregate data only) may limit the choice of methodologies to analyse synthesizable data.A more "open access" culture for research data requires properly managing and accessing the massive amount of potentially sensitive information in a way that will be of optimal use for the scientific community while also ensuring proper protection and respect of participants (including their privacy and confidentiality). The "law" is often blamed for creating "undue hurdles" to international access to research data, but are we focusing on the real problem?We will discuss some ethical, legal and social issues challenges faced by researchers who wish to access multiple research infrastructures to conduct epidemiological research. We also identify avenues of innovative solutions being proposed to meet some of these challenges. The compilation, retrieval, use, storage, and distribution of genotypic and phenotypic data associated with the collection, storage, processing, and distribution of biomaterials managed by biobanks is insatiable. Clinical trials, observational studies, and fundamental basic science research is "pre-qualifying" biomaterials sought and used in research based on the quality of data submitted with a biomaterial as well as the quantifiable data associated with its processing. Additionally, longitudinal designs to study the course of disease may require multiple specimen submissions tied with its time specific associated phenotypic data. Furthermore, significant attention is being given to defining "clinical data elements" or CDE's to assure that data with the most significant clinical relevance are collected at each time interval. Clearly, it is no trivial task to define a CDE and correlate its potential relevance to the research enterprise. This presentation will discuss how said data are collected, evaluated for its relevance (power), and how it is made available to the scientific community using the Coriell Personalised Medicine Collaborative and Coriell's biobanking models as case presentations. This Early Career Researcher (ECR) session will be the first such session at an IEA World Congress of Epidemiology. The session is being held in order to build on the work of an ad hoc ECR Committee which has prepared a report to the IEA Council recommending the creation of a formal IEA ECR group. The session will report on what the ad hoc committee has been doing, and get feedback and suggestions on how to proceed, as well as have a discussion with Professor Cesar Victora and Professor Shah Ebrahim about how to make health research work towards development. It is hoped, and intended, that the incoming IEA Council will then formally establish an ECR group within IEA. This group would aim to develop a network of emerging epidemiolo...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
