RESUMO

Objetivos. Los pescadores que participaron en las actividades de limpieza del vertido del Prestige mostraban un aumento del riesgo de padecer síntomas respiratorios pasados entre uno y dos años después de la catástrofe; sin embargo, la persistencia a largo plazo de estos efectos sobre la salud permanecía incierta. El objetivo del presente estudio ha sido evaluar la persistencia de estos síntomas respiratorios cinco años después de los trabajos de limpieza. Métodos. Subgrupos de 501 pescadores que habían estado expuestos a los trabajos de limpieza y 177 pescadores no expuestos fueron re-entrevistados por teléfono en el 2008, incluyendo las mismas preguntas utilizadas en la encuesta inicial. Las asociaciones entre la participación en los trabajos de limpieza y la presencia de síntomas respiratorios se evaluaron mediante análisis de regresión log-binomial y multinomial, ajustado por sexo, edad y tabaquismo. Resultados. Se obtuvo información de 466 (93%) pescadores expuestos y de 156 (88%) no expuestos. La prevalencia de síntomas del tracto respiratorio bajo (incluyendo sibilancias, falta de aire, tos y flema) disminuyó ligeramente en ambos grupos, pero permaneció más alta entre los expuestos (RR 1,4, IC 95%: 1,1-1,9) El riesgo de tener síntomas respiratorios persistentes(referidos tanto al inicio como durante el seguimiento) aumentó con el nivel de exposición: RR 1,7(IC 95%: 0,9-3,1) y 3,3 (IC 95%: 1,8-6,2) para los moderada y altamente expuestos, respectivamente. El riesgo en relación con la presencia de síntomas nasales y para el uso de medicación respiratoria fue de un orden similar. Conclusiones. La participación en las actividades de limpieza de los derrames de petróleo puede dar lugar a síntomas respiratorios que persisten hasta cinco años después de la exposición. Sería necesario disponer de protocolos para llevar a cabo las medidas preventivas oportunas, así como una continua vigilancia de la salud de los trabajadores que participen en actividades de limpieza en este tipo de accidentes ( AU)


Objectives. Fishermen who had participated in clean-up activities of the Prestige oil spill showed an excess risk of respiratory symptoms 1-2 years later, but the long-term persistence of these health effects is unclear. The aim of this study was to evaluate the persistence of these respiratory symptoms 5 years after clean-up work. Methods. Subgroups of 501 fishermen who had been exposed to clean-up work and 177 non-exposed individuals were re-interviewed by telephone in 2008, including the same symptom questions as in the initial survey. Associations between participation in clean-up work and respiratory symptoms were assessed using log-binomial and multinomial regression analyses adjusting for sex, age and smoking. Results. Information from 466 exposed (93%) and 156 non-exposed (88%) fishermen was obtained. The prevalence of lower respiratory tract symptoms (including wheeze, shortness of breath, cough and phlegm) had slightly decreased in both groups, but remained higher among the exposed (RR 1.4, 95% CI 1.1 to 1.9). The risk of having persistent respiratory symptoms(reported both at baseline and at follow-up) increased with the degree of exposure: RR ratio 1.7 (95% CI 0.9 to 3.1)and 3.3 (95% CI 1.8 to 6.2) for moderately and highly exposed, respectively, when compared with those without any symptoms. Findings for nasal symptoms and for respiratory medication usage were similar. Conclusions. Participation in clean-up activities of oil spills may result in respiratory symptoms that persist up to 5years after exposure. Guidelines for preventive measures and a continued surveillance of clean-up workers of oil spills are necessary(AU)

RESUMO

Obesity is a risk factor for asthma. Adipose tissue expresses pro-inflammatory molecules including tumour necrosis factor (TNF), and levels of TNF are also related to polymorphisms in the TNF-alpha (TNFA) gene. The current authors examined the joint effect of obesity and TNFA variability on asthma in adults by combining two population-based studies. The European Community Respiratory Health Survey and the Swiss Cohort Study on Air Pollution and Lung and Heart Disease in Adults used comparable protocols, questionnaires and measures of lung function and atopy. DNA samples from 9,167 participants were genotyped for TNFA -308 and lymphotoxin-alpha (LTA) +252 gene variants. Obesity and TNFA were associated with asthma when mutually adjusting for their independent effects (odds ratio (OR) for obesity 2.4, 95% confidence interval (CI) 1.7-3.2; OR for TNFA -308 polymorphism 1.3, 95% CI 1.1-1.6). The association of obesity with asthma was stronger for subjects carrying the G/A and A/A TNFA -308 genotypes compared with the more common G/G genotype, particularly among nonatopics (OR for G/A and A/A genotypes 6.1, 95% CI 2.5-14.4; OR for G/G genotype 1.7, 95% CI 0.8-3.3). The present findings provide, for the first time, evidence for a complex pattern of interaction between obesity, a pro-inflammatory genetic factor and asthma.
