Occupational Burden of Asbestos-related Cancer in Argentina, Brazil, Colombia, and Mexico

Background: An estimate at the national level of the occupational cancer burden brought about by the industrial use of asbestos requires detailed routine information on such uses as well as on vital statistics of good quality. A causal association with asbestos exposure has been established for mesothelioma and cancers of the lung, larynx, and ovary. Objectives: The aim of this study was to provide estimates of the occupational burden of asbestos-related cancer for the Latin American countries that are or have been the highest asbestos consumers in the region: Argentina, Brazil, Colombia, and Mexico. Methods: The burden of multifactorial cancers has been estimated through the approach suggested for the World Health Organization using the population attributable fraction. The following data were used: • Proportion of workforce employed in each economic sector • Proportion of workers exposed to asbestos in each sector • Occupational turnover • Levels of exposure • Proportion of the population in the workforce • Relative risk for each considered disease for 1 or more levels of exposure Data on the proportion of workers exposed to asbestos in each sector are not available for Latin American countries; therefore, data from the European CAREX database (carcinogen exposure database) were used. Findings: Using mortality data of the World Health Organization Health Statistics database for the year 2009 and applying the estimated values for population attributable fractions, the number of estimated deaths in 5 years for mesothelioma and for lung, larynx, and ovary cancers attributable to occupational asbestos exposures, were respectively 735, 233, 29, and 14 for Argentina; 340, 611, 68, and 43 for Brazil; 255, 97, 14, and 9 for Colombia, and 1075, 219, 18, and 22 for Mexico. Conclusions: The limitations in compiling the estimates highlight the need for improvement in the quality of asbestos-related environmental and health data. Nevertheless, the figures are already usable to promote a ban on asbestos use

Educazione sanitaria sugli effetti della guerra: progetto pilota di comunicazione scientifica nelle scuole

Deaths and injuries are the most immediate effects of war, but war also causes living conditions to fall below minimum levels, favours the spread of disease and makes health interventions difficult. Thus the first victims of modern war are civilians. A communication project aimed at raising awareness among youth on the effects of conflicts on the health conditions of the population has been developed. Three case studies have been identified: acute emergency (Darfur), chronic conflict (Palestine), historic conflict (Vietnam) - collecting scientific documentation on the health effects of war in these countries. Three school modules have been developed, providing the students with extracurricular scientific tools for dealing with the subject "war and health". This document describes the implementation of the modules on a class of secondary school and offers suggestions for further implementations by epidemiologists and teachers

Silicosis mortality in Italy: temporal trends 1990-2012 and spatial patterns 2000-2012

The present study investigates the occurrence of silicosis in Italy and its temporal trends and spatial patterns using mortality data. The aim is to give a contribution, albeit with a conservative estimate inferred from mortality data, to epidemiological knowledge of silicosis in Italy. Trends in mortality due to silicosis from 1990 to 2012 were evaluated and a municipal cluster analysis was performed. It shows that mortality due to silicosis is declining but still not eradicated and that one of its main features is regional variability: in this respect, the cluster analysis performed allowed to identify 34 different geographic areas. The results obtained may help display a more detailed picture of silicosis epidemiology and contribute to the fight against exposure to silica, an undisputable public health commitment

Fostering public health awareness on risks in contaminated sites. Capacity building and dissemination of scientific evidence

 The article focuses on the multidisciplinary nature of public health and the need to develop target oriented capacity building and dissemination plans taking into account both scientific evidence and the information needs of the different stakeholders. In particular, issues regarding stakeholders’ involvement in epidemiological studies in contaminated sites, considering their different levels of awareness on risk characterization and management, are discussed. In a public health perspective, the main stakeholders in ntaminated sites re researchers and public health officers, risk managers and policy makers, population esiding in the contaminated areas, environmental associations, patient’s organizations. The different components of a dissemination strategy addressed to different stakeholders are analyzed with the objective to create awareness and preparedness to facilitate management in contaminated sites, foster scientific knowledge and informed decisions to consolidate risk perception through science-driven information.

Exploring available options in characterising the health impact of industrially contaminated sites

Industrially contaminated sites (ICS) are of high concern from an environmental public health perspective, since industrial plants may produce a widespread contamination that can result in several health impacts on the populations living in their neighbourhood. The objective of this contribution is to briefly explore available options in studying the health impact of ICS, mainly referring to information provided by documents and activities developed by the WHO and the WHO Collaborating Center for Environmental Health in Contaminated Sites. In current practice the health impact of ICS is evaluated using studies and assessments falling in two broad types of strategies: one based on epidemiology and the other on risk assessment methods. In recent years, traditional approaches to assess relationships between environmental risks and health has been evolved considering the intricate nature between them and other factors. New developments should be explored in the context of ICS to find common strategies and tools to assess their impacts and to guide public health interventions

A stratified compartmental model for the transmission of Sparicotyle chrysophrii (Platyhelminthes: Monogenea) in gilthead seabream (Sparus aurata) fish farms

The rapid development of intensive fish farming has been associated with the spreading of infectious diseases, pathogens and parasites. One such parasite is Sparicotyle chrysophrii (Platyhelminthes: Monogenea), which commonly infects cultured gilthead seabream (Sparus aurata)—a vital species in Mediterranean aquaculture. The parasite attaches to fish gills and can cause epizootics in sea cages with relevant consequences for fish health and associated economic losses for fish farmers. In this study, a novel stratified compartmental epidemiological model of S. chrysophrii transmission was developed and analysed. The model accounts for the temporal progression of the number of juvenile and adult parasites attached to each fish, as well as the abundance of eggs and oncomiracidia. We applied the model to data collected in a seabream farm, where the fish population and the number of adult parasites attached to fish gills were closely monitored in six different cages for 10 months. The model successfully replicated the temporal dynamics of the distribution of the parasite abundance within fish hosts and simulated the effects of environmental factors, such as water temperature, on the transmission dynamics. The findings highlight the potential of modelling tools for farming management, aiding in the prevention and control of S. chrysophrii infections in Mediterranean aquaculture
