Malignant asbestos‐related disease in a population exposed to asbestos

Abstract Objectives: The first asbestos fiber cement plant in Spain operated in Cerdanyola, in the Barcelona metropolitan area, between 1907 and 1997. We describe clinical and epidemiological characteristics of patients diagnosed with the malignant asbestosrelated disease (ARD) in the area of the plant between 2007 and 2016. Methods: A prospective, descriptive study was undertaken in the 12 municipalities of the county of Barcelona most proximate to the plant. We describe malignant ARD cases by time of diagnosis, source of exposure, periods of exposure and latency, and distribution by sex. Cumulative incidence and age‐standardized incidence rates (ASIR) are calculated. Results: Of 477 patients diagnosed with ARD between 2007 and 2016, 128 (26%) presented with asbestos‐associated malignancy. Pleural mesothelioma was noted in 105 patients (82.0%) with a linear trend Z‐score of −0.2 (NS) in men and 2.7 (P < .01) in women. The highest ASIRs for malignant ARD (6.1/100 000 residents/year; 95% confidence interval [CI], 2.2‐13.3) and pleural mesothelioma (4.8/100 000 residents/ year; 95% CI, 1.5‐11.6) occurred in municipalities closest to the focal point of contamination. The origin of malignant ARD was nonoccupational in 32.2% of men and 81.6% of women (P < .001). Conclusions: More than 20 years after the closure of the fiber cement plant, the grave consequences of exposure to asbestos remain. The detection of cases of pleural mesothelioma in men seems to have plateaued whereas in women an ascending trend continues, which principally has its origin in nonoccupational exposures

Risk factors of mortality from all asbestos-related diseases: A competing risk analysis.

Background. The mortality from all malignant and nonmalignant asbestos-related diseases remains unknown. The authors assessed the incidence and risk factors for all asbestos-related deaths. Methods. The sample included 544 patients from an asbestos-exposed community in the area of Barcelona (Spain), between Jan 1, 1970, and Dec 31, 2006. Competing risk regression through a subdistribution hazard analysis was used to estimate risk factors for the outcomes. Results. Asbestos-related deaths were observed in 167 (30.7%) patients and 57.5% of these deaths were caused by some type of mesothelioma. The incidence rate after diagnosis was 3,600 per 100,000 person-years. In 7.5% of patients death was non-asbestos-related, while pleural and peritoneal mesothelioma were identified in 87 (16.0%) and 18 (3.3%) patients, respectively. Conclusions. Age, sex, household exposure, cumulative nonmalignant asbestos-related disease, and single malignant pathology were identified as risk factors for asbestos-related death. These findings suggest the need to develop a preventive approach to the community and to improve the clinical follow-up process of these patients

Risk factors associated with asbestos-related diseases: a community-based case-control study

Abstract Background: Asbestos is a first level carcinogen. However, few epidemiological studies analyse the risk and protective factors associated with asbestos-related diseases and follow up these conditions in the general population. Pleural mesothelioma, caused by inhalation of asbestos fibres at work, at home or in the environment, is the most representative asbestos-related disease. The objectives of this study are to analyse the risk and protective factors associated with asbestos-related diseases and to investigate the incidence of new clinical manifestations in patients already diagnosed with some form of ARD. Methods/Design: We have designed a matched case-control study with follow up of both cohorts from a population of a health district of the Barcelona province that has been exposed to asbestos for a period of 90 years. Discussion: A better understanding of asbestos-related diseases should improve i) the clinical and epidemiological follow up of patients with this condition; ii) the design of new treatment strategies; iii) and the development of preventive activities. At the end of the study, the two cohorts created in this study (affected cases and healthy controls) will constitute the basis for future research

Evaluación de la gestión de los casos de incapacidad temporal por contingencia común de más de 15 días en Cataluña Evaluation of the management of nonwork-related sick leave lasting more than 15 days in Catalonia (Spain)

Objetivos: Comparar la duración de los casos de incapacidad temporal por contingencia común gestionados por las mutuas con los gestionados por el Instituto Nacional de la Seguridad Social (INSS). Métodos: Cohorte retrospectiva de 289.686 casos de incapacidad de más de 15 días de duración iniciados en 2005 tras su certificación por un médico de primaria en Cataluña (156.676 gestionados por el INSS), registrados en el Institut Català d'Avaluacions Mèdiques, y seguidos hasta su alta. La duración mediana y los percentiles fueron calculados con el estimador de Wang-Chang, que tiene en cuenta los episodios repetidos (25% aproximadamente), y se compararon mediante un modelo de regresión log-logístico con fragilidad gamma compartida, lo que permite estimar la razón de tiempo (RT) y su intervalo de confianza del 95% (IC95%). Resultados: La duración mediana fue de 43 días para los casos del INSS y de 39 para los de mutuas. Esta diferencia fue estadísticamente significativa para los hombres del régimen general (RT=0,87; IC95%: 0,85-0,88) y del régimen de autónomos (RT=0,78; IC95%: 0,75-0,80), y para las mujeres del régimen general (RT=0,85; IC95%: 0,84-0,87) y de autónomos (RT=0,84; IC95%: 0,81-0,88); diferencias que se mantienen en general después de ajustar por la edad y la región sanitaria. Conclusiones: Los resultados confirman una finalización de los episodios más rápida para los casos de más de 15 días de duración gestionados por una mutua que para los gestionados por el INSS, tanto aquellos del régimen general como de autónomos. Es necesario investigar las causas de estas diferencias.Objectives: To compare the length of nonwork-related sick leave among cases managed by an insurance company versus those managed by the National Institute of Social Security (NISS). Methods: We performed a retrospective cohort study of 289,686 cases of sick leave lasting for more than 15 days that began in 2005 after certification by a primary care physician in Catalonia, were reported to the Catalonian Institute of Medical Evaluations, and were followed to term. Of the total, 156,676 cases were managed by the NISS. To account for repeat episodes (approximately 25% of the total), the Wang-Chang estimator was used to calculate the median duration and percentiles; comparisons were made using log-logistic regression with shared gamma frailty models, with calculation of time ratios (TR) and their corresponding 95% confidence intervals (95% CI). Results: The median duration of sick leave was 43 days for cases managed by the NISS and 39 days for those managed by the insurance company. This difference was statistically significant both for men employed under contract (TR=0.87; 95% CI: 0.85-0.88) and for those who were self-employed (TR=0.78; 95% CI: 0.75-0.80) as well as for women under contract (TR=0.85; 95% CI: 0.84-0.87) and self-employed women (TR=0.84; 95% CI: 0.81-0.88). These differences persisted after adjustment was performed for age and health region. Conclusions: For sick leave lasting more than 15 days, these results confirm that cases managed by an insurance company ended earlier than for those managed by the NISS, both for contract and self-employed workers. Further research is needed to explore the reasons for these differences

Distribución de la duración de la incapacidad temporal por contingencia común por diagnóstico médico (Cataluña, 2006-2008) Distribution of the duration of nonoccupational sick leave by medical diagnosis (Catalonia, Spain, 2006-2008)

Presentamos una herramienta sencilla y práctica que permite consultar la distribución habitual de la duración de la incapacidad temporal por contingencia común, según el diagnóstico médico. Para ello se analizaron 2.646.352 episodios de incapacidad temporal ocurridos en Cataluña y seguidos hasta el alta, entre 2006 y 2008, incorporados a un aplicativo. La duración mediana, dado que sigue una distribución asimétrica, fue de 9 días. Los trastornos musculoesqueléticos fueron el grupo diagnóstico más frecuente (22,5%) y las neoplasias tuvieron la duración mediana más larga (56 días). Los diagnósticos específicos más comunes fueron la diarrea-gastroenteritis (8,2%; mediana: 3 días) y la rinofaringitis aguda (5,2%; mediana: 4 días). La distribución de la duración de la incapacidad temporal en una población varía por diagnóstico y es asimétrica; la mayoría de los episodios duran mucho menos que la media. Esta información es importante para una mejor gestión, tanto clínica como administrativa, de la incapacidad temporal.We present a simple and practical tool that allows the usual distribution of the duration of non-occupational sick leave to be determined by medical diagnosis. A total of 2,646,352 episodes of medically certified sick leave, registered by the Catalan Institute of Medical Evaluations for the period 2006-2008, were followed to closure and were entered into a spreadsheet. Given its asymmetric distribution, the median duration of sick leave was 9 days. Musculoskeletal disorders were the most frequent diagnostic group (22.5%), while neoplasms had the longest median duration (56 days). The most common specific diagnoses were diarrhea-gastroenteritis (8.2%; median: 3 days) and acute rhinopharyngitis (5.2%; median: 4 days). The distribution of the duration of sick leave in a population varies by diagnosis and is asymmetric, with most episodes being much shorter than the mean duration. This finding is important for better clinical and administrative management of sick leave episodes

La incapacidad temporal atribuible al consumo de tabaco en trabajadores de 35-64 años. Cataluña, 2007-2016

ABSTRACT Background: Few recent studies have researched into the size and trends of the impact of tobacco use on productivity losses. The objective of this work was to describe the percentage of episodes and non work-related sick leave days with a duration over 5 days due to tobacco use in Catalonia in the period 2007-2016 in relation to the total sick-leave episodes and sick leave days in patients aged 35-64. Methods: Descriptive study of 3,627,107 episodes and 237,219,230 days in sick-leave by any cause, except those work-related, in workers aged 35-64. Population etiological fractions were used. The annual percentage of number of episodes and sick-leave days due to tobacco use in relation with total episodes and sick-leave days was calculated and a trend test was performed. Results: The percentage of sick-leave episodes and days due to tobacco use was higher in men (3.9%; 5.5% respectively) than in women (2.3%; 1.5% respectively). The trend for sick-leave due to tobacco use was positive, with a maximum OR in 2013. For the number of sick-leave episodes due to tobacco use, the corrected Z was 25.3 in men (p < 0.001) and 49.4 in women (p < 0.001). For sick-leave days due to tobacco use, the corrected Z was 36.9 in men (p < 0.001) and 250.4 in women (p < 0.001). Conclusions: About 3% of sick-leave episodes with a duration over than 5 days are due to tobacco use, with a positive trend in both sexes. It is necessary to continue reinforcing the tobacco prevention and control policies in order to improve such trends for years to come.RESUMEN Fundamentos: Pocos estudios recientes han investigado en nuestro medio la magnitud y las tendencias del impacto del consumo de tabaco en la pérdida de productividad. El objetivo de este trabajo fue describir la proporción de episodios y de días en incapacidad temporal no profesional de duración superior a 5 días y atribuible al consumo de tabaco en Cataluña en el período 2007-2016, respecto del total de incapacidad temporal en trabajadores de 35-64 años. Métodos: Estudio descriptivo de 3.627.107 episodios y 237.219.230 días de incapacidad temporal por todas las causas, excepto las de origen profesional, en trabajadores de 35-64 años. Se aplicaron las fracciones etiológicas poblacionales. Se calculó la proporción anual de episodios y de días en incapacidad temporal atribuible (ITA) respecto de la incapacidad temporal (IT) por todas las causas y se realizó un test de tendencia. Resultados: El porcentaje de episodios y de días en ITA por consumo de tabaco fue superior en hombres (3,9%; 5,5% respectivamente) que en mujeres (2,3%; 1,5% respectivamente). La tendencia de la ITA fue ascendente, con un OR máximo en 2013. Para los episodios de ITA, la Z corregida fue 25,3 en hombres (p<0,001) y 49,4 en mujeres (p<0,001). Para los días en ITA, la Z corregida fue 36,9 en hombres (p<0,001) y 250,4 en mujeres (p<0,001). Conclusiones: Alrededor de un 3% de los episodios de IT de 5 días o más son atribuibles al tabaco, con una tendencia ascendente en ambos sexos. Es necesario continuar reforzando las políticas de prevención y control del tabaquismo para mejorar esta tendencia

Occupational health impact of the 2009 H1N1 flu pandemic: Surveillance of sickness absence

Objectives: Workplace absences due to illness can disrupt usual operations and increase costs for businesses. This study of sickness absence due to influenza and influenza-related illness presents a unique opportunity to characterise and measure the impact of the 2009 (H1N1) pandemic, by comparing trends during the pandemic to those of previous years, and adding this information to that obtained by traditional epidemiological surveillance systems. Methods: We compared the numbers of cases of sickness absence due to illness caused by influenza and influenza-related illness in 2007-2009, and in the first 3 months of 2010 in Catalonia (n=811 940) using a time series approach. Trends were examined by economic activity, age and gender. The weekly endemic-epidemic index (EEI) was calculated and its 95% CI obtained with the delta method, with observed and expected cases considered as independent random variables. Results: Influenza activity peaked earlier in 2009 and yielded more cases than in previous years. Week 46 (in November 2009) had the highest number of new cases resulting in sickness absence (EEI 20.99; 95% CI 9.44 to 46.69). Women and the 'education, health and other social activities' sector were the most affected. Conclusions: Results indicate that the new H1N1 pandemic had a significant impact on business, with shifts in the timing of peak incidence, a doubling in the number of cases, and changes in the distribution of cases by economic activity sector and gender. Traditional epidemiological surveillance systems could benefit from the addition of information based on sickness absence data.Peer Reviewe

Comparisson in Andalusia and Catalonia of sickness absence because of influenza (H1N1) 2009 | Comparación entre Andalucía y Cataluña de la frecuencia de incapacidad laboral durante la gripe (H1N1) 2009

Background: This study compared surveillance of cases of sickness absence due to illness caused by influenza and reported in Andalusia and Catalonia in the period 2007-2009. Methods:Atime series of incident cases of sickness absence due to influenza, by sex and age, in which episodes in Andalusia and Catalonia in a previous epidemic period (from 01/01/2007 through 30/09/2009) were compared to the pandemic period (last three months of 2009). The weekly number of new cases of sickness absence due to influenza was calculated, and the minimum, median and maximum values were plotted for each of these two periods. Results: Unexpectedly, women had a higher proportion of new cases of sickness absence due to influenza during the pandemic period (52.2% in Catalonia and 49.7% in Andalusia). During both periods the 25 to 34 year old age group had a higher number of new cases of sickness absence both in Catalonia (37.439 in the epidemic period and 15.379 in the pandemic) and Andalusia (20.465 epidemic period and 9.630 pandemic period).The arrival of the pandemic was around November (approximately 10.000 cases in Catalonia and 5.000 cases in Andalusia), resulting in a significant increase of cases in contrast to the median of the epidemic period. Conclusions: During the 2009 pandemic, there was an increase in new cases of sickness absence due to influenza, somewhat greater in Catalonia than Andalusia, with an earlier peak in November, especially among women in these two autonomous communities.Background: This study compared surveillance of cases of sickness absence due to illness caused by influenza and reported in Andalusia and Catalonia in the period 2007-2009.

Duración de los episodios de incapacidad temporal por contingencia común según regiones sanitarias en Cataluña

Fundamentos: En este estudio se analizó la duración de los episodios de incapacidad temporal por contingencia común en Cataluña según regiones sanitarias. Partiendo de la hipótesis de una distribución homogénea de las duraciones entre las regiones sanitarias. Métodos: Estudio de cohorte retrospectiva de 811.790 episodios obtenidos del Institut Català d�Avaluacions Mèdiques iniciados el año 2005 y seguidos hasta su finalización, cómo máximo julio de 2007, donde se describió la mediana de la duración en días de los episodios para cada una de las siete regiones sanitarias de Cataluña. La probabilidad de volver al trabajo se representó según las curvas de supervivencia de Wang_Chang y se comparó la duración mediana (DM) tomando como referencia la Región Sanitaria Barcelona, estratificando por sexo. Resultados: La región de Camp de Tarragona registra la menor duración de 5 días. Por contra, los episodios ocurridos en el Alt Pirineu i Aran presentaron una mayor duración de 13 días. Para la región de Barcelona la duración fue 7 días, al igual que para Cataluña Central. En Girona fue de 8 días, y en Lleida y Terres de l�Ebre de 9 días. Conclusiones: Existen diferencias significativas en las duraciones de los episodios entre las regiones sanitarias de Cataluña, que se mantienen después de ajustar por la edad, la gestión del episodio y el régimen de Seguridad Social, tanto para hombres como para mujere
