Exposição à endotoxina no ambiente de trabalho e pesquisa de associação com asma, alergia e sibilo / Endotoxin exposition in workplaces and research association with asthma, allergy and wheezing

Freitas, Amanda de Souza 10 April 2014 (has links)
Em países industrializados, as doenças pulmonares são as que mais se destacam quando o assunto é doença ocupacional. Entre os técnicos, cuidadores de animais, médicos e cientistas, as doenças respiratórias e alérgicas a animais de laboratório representam a principal doença ocupacional. Entre os agentes presentes na sujeira orgânica, as endotoxinas são as mais relacionadas às respostas inflamatórias e causadoras de uma série de doenças respiratórias. As endotoxinas, componentes externos das bactérias gram-negativas, são encontradas em várias concentrações em suspensão no ar ou depositadas na poeira do chão, em materiais e equipamentos, no ambiente domiciliar, urbano, rural e em alguns estabelecimentos. É inevitável a exposição à endotoxina, no entanto, o nível de exposição das vias aéreas pode ser muito variado. Alguns estudos mostraram a correlação dos sintomas apresentados pelos trabalhadores de laboratórios ou biotérios com o nível de exposição às endotoxinas. OBJETIVOS: Avaliar a exposição às endotoxinas, presentes na poeira de laboratórios e biotérios e a sua relação com asma, rinite e atopia apresentadas pelos trabalhadores. MÉTODOS: Trata-se de um estudo transversal, realizado na Universidade de São Paulo, campus Ribeirão Preto (USP-RP) e na Universidade Estadual de Campinas (UNICAMP). Foram coletadas amostras de poeira do chão de laboratórios e biotérios que continham rato, camundongo, cobaia, coelho ou hamster; e em laboratórios e salas administrativas que não tinham contato algum com esses animais. As amostras de poeira foram analisadas e a quantidade de endotoxina foi dosada pelo método Limulus amebocyte lysate (LAL). Esta quantidade foi relacionada com variáveis clínicas dos trabalhadores destes locais (sintomas, reatividade brônquica, espirometria e testes alérgicos). RESULTADOS: Foram coletadas amostras de poeira de 145 locais de trabalho. Destes, 74 (51%) da USP-RP e 71 (49%) da UNICAMP. Noventa e dois (63%) locais de trabalho continham animais de laboratório (57 da USP-RP e 35 da UNICAMP) e 53 não os continham (17 da USP-RP e 36 da UNICAMP). Foram utilizados os dados de 751 trabalhadores, 412 formaram o grupo exposto a animais de laboratório e 339 o grupo não exposto. O grupo exposto a animais de laboratório apresentou maior quantidade de endotoxina, 55 ± 79 UE por mg de poeira, quando comparado com o grupo não exposto, 19 ± 27 UE/mg (p < 0,001 pelo teste t de Student). Quando estratificada, a quantidade de endotoxina em elevada e baixa quantidade, a alta concentração (acima de 20,4 UE/mg) de endotoxina se associou ao relato de sibilos nos últimos 12 meses. Ou seja, 27% dos trabalhores expostos a elevadas concentrações relataram sibilos (p < 0,01 pelo teste do qui-quadrado). Porém, a quantidade de endotoxina não se associou com sintomas de rinite, com atopia, com o teste de hiperreatividade brônquica positiva. CONCLUSÃO: A exposição à endotoxina apresenta efeito no sistema respiratório dos trabalhadores mesmo não tendo se associado à asma. A alta concentração de endotoxina se associou com a presença de sibilos, ou seja, os trabalhadores de biotérios e de laboratórios que tem contato direto com animais de laboratório estão mais susceptíveis a apresentarem sibilos ao longo do ano, sendo necessárias medidas de prevenção para estes trabalhadores. / Respiratory diseases are the most common occupational illnesses in industrialized countries and, among them, asthma and allergies are highly prevalent. Respiratory diseases and laboratory animal allergies represent a major occupational illness among technicians, animal caretakers, doctors and scientists whose work requires such exposure. Among particles present on organic dust, endotoxin is the most related to the inflammation witch cause a numerous respiratory diseases. Endotoxin from gram-negative bacterias are airborne and found in different concentrations in dust and on the ground of home and rural environment, indoor or outdoor living areas. Exposure to endotoxin is unpreventable, but the degree of exposure may vary. Some studies have shown correlation between workers symptoms with degree of exposure. AIMS: Our aim was to evaluate amount of endotoxin exposure in laboratories and animal facilities and to test its association with asthma, rhinitis, and atopy presented by workers. METHODS: This is a cross-sectional study performed in the University of São Paulo, campus of Ribeirão Preto (USP-RP) and in the State University of Campinas (Unicamp). Dust samples were collected from laboratories and animal facilities with rat, mouse, guinea pig, rabbit or hamster. We also sampled workplaces without animals. These samples were analyzed by the method of Limulus amebocyte lysate (LAL). The concentration of endotoxin detected in those workplaces were tested for association with symptoms, bronchial hyperresponsiveness, spirometry data and skin prick test results. RESULTS: One hundred, forty-five workplaces had their dust sampled: 74 (51%) in USP-RP and 71 (49%) in Unicamp. Among those, 92 (63%) workplaces had laboratory animals (57 in USP-RP and 35 in UNICAMP) and 53 (37%) did not have animals. These workplaces had 751 workers or students, 412 were animal handlers and 339 were nonhandlers. Animal handlers workplaces were exposed to higher concentrations of endotoxin 55 ± 79 UE/mg as compared with the non-handlers group 19 ± 27 UE/mg (p < 0.001, Studentst test). We divided endotoxin concentration into two leves: high (> 20.4 UE/mg) and low concentration. The high concentration associated with wheezing prevalence, i.e. 27% of animal handlers exposed to high concentration reported wheezing in the last 12 months (p < 001, chi-squared test). The concentration of endotoxin was not associated with symptoms of rhinitis, atopy or bronchial hyperresponsiveness. CONCLUSION: Exposure to endotoxin has effect on workers respiratory system, although it is not associated with asthma. Higher endotoxin concentration is associated with wheezing. Therefore, animal handlers are prone to present wheezing and preventive measures are necessary for these workers.

Risco de desordens músculo-esqueléticas nos membros superiores de graduandos de Odontologia /

Sasso Garcia, Patrícia Petromilli Nordi. January 2009 (has links)
Resumo: Este estudo teve por objetivo avaliar o risco de desenvolvimento de desordens músculo-esqueléticas nos membros superiores de graduandos de Odontologia considerando as variáveis sexo, tipo de procedimento clínico executado, região da boca tratada e prática do trabalho a quatro mãos. Foram avaliados alunos, de ambos os sexos, matriculados no oitavo semestre do curso de graduação da Faculdade de Odontologia de Araraquara - UNESP. Foram efetuadas tomadas fotográficas durante a realização de 283 procedimentos clínicos, utilizando-se máquina fotogrática digital. Para análise das fotografias, utilizou-se o programa Image Tool. As posturas de trabalho adotadas por cada estudante na sua atuação como "operador" foram observadas pelo método RULA (Rapid Upper Limb Assessment), o qual inclui o uso de um diagrama de análise de postura do indivíduo e três tabelas de escores que permitem a avaliação da exposição aos fatores de risco para o desenvolvimento de desordens músculo-esqueléticas. As fotografias foram analisadas por um professor da área de ergonomia calibrado (_=0,91). Para cada procedimento foi atribuído um escore de risco final. Os procedimentos executados foram classificados em duas grandes categorias: procedimentos preparatórios e procedimentos restauradores/reabilitadores. Os dados de risco de desordens músculoesqueléticas nos membros superiores foram apurados, e sua prevalência foi estimada por ponto e por intervalo de confiança de 95%. O estudo da associação do risco de desordens músculo-esqueléticas às variáveis de interesse foi realizado por meio do Teste de Qui-quadrado (_ 2). O nível de significância adotado foi de 5%. Observou-se que na maioria dos procedimentos executados o risco de desordens músculo-esqueléticas segundo a classificação...

Dental students of both sexes enrolled in the 8th semester in Araraquara School of Dentistry - UNESP were photographed while practicing 283 dental procedures, by using digital camera. Their postures were evaluated with the help of Image Tool Software. Working postures of each "operator" student were evaluated by the Rapid Upper Limb Assessment (RULA) methodology, which involves the use of diagrams of body postures and three scoring tables and risk scores enabled the evaluation of risk exposure to musculoskeletal disorders. The collected pictures were then evaluated by a calibrated professor of Dental Ergonomics (kappa statistics=0.91), and for each analysed procedure it was attributed a final risk score. Then, the dental procedures were classified in two major categories: preparatory procedures and restorative/rehabilitation procedures. The prevalence of risk of developing musculoskeletal disorders was estimated by point and by 95% of confidence interval. The association between the risk of developing disorders and variables of interest were assessed by the chisquare test (_2) with the significance level of 5%. Results showed that the risk of developing musculoskeletal disorders was high, regarding most dental procedures performed by the undergraduate students...

Odpovědnost za škodu při pracovních úrazech a nemocech z povolání / The liability for damages caused by work-related accidents and occupational diseases

Všetečková, Monika January 2016 (has links)
This diploma thesis deals with the employer's liability for damages caused by work-related accidents or occupational diseases of his employees. The reason for choosing this topic was partly because of the author's experience with the assessment of work-related accidents in legal proceedings, partly due to the high- frequency of work-related accidents and also the fact, the results of work-related accidents and occupational diseases not rarely cause a long-term adverse repercussion in real life of an employee. The main point of this thesis is to analyse elements of stated employer's liability for damages. Using the case law, detailed analysis of the concept of work- related accidents is performed in the same chapter. There are analysed specific situations with conclusions if the injury can be evaluated as an work-related accident or not. Besides work-related accidents, occupational diseases and other elements of liability, this chapter deals with the possibility of an employer to be absolved from any liability as well. Case law concerning the absolution from liability is also included in this chapter. The essential part of this thesis is also the enumeration of employer's obligations connected to the fact his employee has suffered a work-related accident or an occupational disease. The most...

Estudo de aspectos profissionais e psicossociais no trabalho e a depressão em enfermeiros atuantes em ambiente hospitalar / Study of professional and psychosocial work aspects and depression in nurses working at hospital environment.

Manetti, Marcela Luísa 27 January 2010 (has links)
O trabalho em Enfermagem tem sido objeto de inúmeras pesquisas, sobretudo pela possibilidade de adoecimento físico e mental dos trabalhadores devido a peculiaridades do processo e das condições de trabalho oferecidas pelas instituições de saúde. As hipóteses testadas foram: H1 - Os aspectos profissionais (carga horária, setor e turno de atuação), psicossociais do ambiente laboral (demanda psicológica e física, controle, apoio social e insegurança), o tipo de trabalho e a exposição ao estresse ocupacional são fatores associados ao aumento de depressão nos enfermeiros, após o controle das demais variáveis; H2 - A adição do apoio social influencia a relação entre demanda psicológica e controle no trabalho e a depressão nos enfermeiros, após o controle das demais variáveis. O objetivo foi avaliar os aspectos profissionais e psicossociais do trabalho em ambiente hospitalar e a presença de depressão em enfermeiros. Trata-se de um estudo observacional, descritivo e correlacional, tipo corte transversal do qual participaram 292 enfermeiros de um hospital universitário do interior do Estado de São Paulo. A coleta de dados foi realizada, no período de março a maio de 2009, por meio da aplicação de três instrumentos: Formulário de Identificação do Trabalhador, Questionários do Conteúdo do Trabalho (JCQ) e Inventário de Depressão de Beck - I (BDI-I). Os instrumentos escalares obtiveram de forma geral valores substanciais ou quase perfeitos. O BDI-I obteve alfa de Cronbach 0,83. As dimensões do JCQ obtiveram coeficiente alfa: demanda psicológica 0,72; controle 0,76 e sub-dimensões uso de habilidades 0,69 e autoridade decisória 0,59; demanda física 0,81; apoio social 0,79 e sub-dimensões apoio social dos supervisores 0,82 e apoio social dos colegas 0,71; e insegurança no trabalho 0,20. Quanto à caracterização dos participantes, a maioria era do sexo feminino (91,10%), casados (49,32%), com idade média de 38,6 anos. 45,21% revelaram ter apresentado mudança significativa em sua vida no último ano e 22,22% dessas mudanças eram relativas ao trabalho. Os trabalhadores eram servidores públicos (81,2%), ocupavam cargo de enfermeiro (70,89%), com tempo médio de atuação no hospital de 11,13 (DP±8,77) anos e carga horária de trabalho semanal média de 42,81h (DP±13,62). Quanto aos aspectos psicossociais no trabalho, as prevalências e médias das dimensões foram: alta demanda psicológica - 49,66% e 32,71 (DP±5,90); baixo controle no trabalho - 50,34% e 68,10 (DP±10,22); baixo uso de habilidades - 50,00% e 34,87 (DP±5,42); baixa autoridade decisória - 82,19% e 33,23 (DP±6,35); alta demanda física - 48,97% e 11,67 (DP±2,71); baixa insegurança - 81,16% e 5,05 (DP±2,44); baixo apoio social no trabalho - 82,88% e 22,41 (DP±3,43); baixo apoio do supervisor - 88,36% e 10,92 (DP±2,52); baixo apoio dos colegas - 84,93% e 11,49 (DP±1,58). Dentre os participantes, os tipos de trabalho vivenciados foram: alta exigência (23,63%), trabalho ativo (26,03%), trabalho passivo (26,71%) e baixa exigência (23,63%). Quanto à exposição ao estresse ocupacional os enfermeiros distribuíram-se entre exposição intermediária (52,74%), maior exposição (23,63%) e sem exposição (23,63%). Entre os enfermeiros 9% apresentaram presença de sintomas indicativos de depressão, classificados como depressão leve (5,14%) e depressão moderada (3,77%), com escore médio de 7,24 (DP±5,77). A hipótese 1 foi parcialmente confirmada e dentre os aspectos relacionados a depressão propostos no modelo final estão: demanda psicológica, controle, apoio social, demanda física, trabalho em alta exigência, maior exposição ao estresse ocupacional, carga horária de trabalho e unidade clínica, cirúrgica e ambulatorial. A hipótese 2 foi parcialmente confirmada e o apoio social demonstrou influenciar a medida da demanda psicológica e da sub-dimensão uso de habilidades. Dessa forma, as condições de trabalho vivenciadas pelos enfermeiros no ambiente hospitalar implicam em depressão e, possivelmente, em outras conseqüências para a saúde desses profissionais. / The work in Nursing has been object of numerous studies because of the potential for physical and mental damage to workers due to peculiarities of the process and the work conditions found in health institutions. The following hypotheses had been tested: H1 - The professional aspects (work hours, work unit and work shift), the psychosocial work aspects (psychological and physical demand, control, social support and insecurity), the type of work and the exposure to occupational stress are factors associated to the increase of depression in nurses, after the control of the others variables; H2 - The addition of social support influences the relation between psychological job demand and job control and the depression in nurses, after the control of the others variables. This observational, descriptive, correlational and crosssectional study aimed to evaluate the professional and psychosocial work aspects at hospital environment and the presence of depression in nurses. In total, 292 nurses from one university hospital have participated in this study. The data collection was realized, from March to May of 2009, through the application of three instruments: form of identification of worker, Job Content Questionnaire (JCQ) and Beck Depression Inventory - I (BDI-I). In general, the instruments had substantial or almost perfect values for Cronbach\'s Alpha. For BDI-I, alpha was 0.83. For JCQ\' dimensions, the values were: psychological job demand 0.72; job control 0,76 and its sub-dimensions skill discretion 0.69 and decision authority 0.59; physical demand of work 0.81; social support at workplace 0.79 and its sub-dimensions social support from supervisors 0,82 and social support from colleagues 0.71; and job insecurity 0.20. Among the participants, most were female (91.10%), married (49.32%), with average age of 38.6 years. 45.21% had significant and recent life event and 22.22% of these events were related to work. In regard to the work, most were public employees (81.2%), registered nurses (70.89%), with average time of performance in the hospital of 11.13 years (DP±8.77) and average of work hours per week 42.81 hours (DP±13.62). The prevalence and average of the psychosocial work aspects were: high psychological job demand - 49.66% and 32.71 (DP±5.90); low job control - 50.34% and 68.10 (DP±10.22); low skill discretion - 50.00% and 34,87 (DP±5.42); low decision authority - 82.19% and 33.23 (DP±6.35); high physical demand - 48.97% and 11.67 (DP±2.71); low insecurity - 81.16% and 5.05 (DP±2.44); low social support - 82.88% and 22.41 (DP±3.43); low support from supervisor - 88.36% and 10.92 (DP±2.52); low support from colleagues - 84.93% and 11.49 (DP±1.58). Among the participants, the types of work experienced were: high-strain job (23.63%), active job (26.03%), passive job (26.71%) and low-strain job (23.63%). According to the level of exposure to occupational stress, the nurses were divided into intermediate exposure to stress (52.74%), high exposure to stress (23.63%) and without exposure to stress (23.63%). Among the nurses, 9% of them have indicated depression symptoms, classified as minor depression (5.14%) and moderate depression (3.77%), with average score of 7,24 (DP±5.77). Hypothesis 1 was partially confirmed and the work aspects related to depression in the final model were: psychological job demands, job control, social support at workplace, physical demands of work, high-strain jobs, high exposure to occupational stress, work hours and clinical, surgical and ambulatory units. Hypothesis 2 was partially confirmed and the social support dimension has demonstrated its influence to the measure of the psychological job demand and the subdimension skill discretion. Thus, the working conditions faced by nurses at hospital environment imply in depression and, possibly, in other consequences for the health of these professionals.
