Pneumoconiosis in iron ore surface mining in Labrador

A cross-sectional survey of the work force at an iron ore surface mine and beneficiation plant in Labrador identified cases with a radiologic diagnosis compatible with simple pneumoconiosis by the International Labour Organization (ILO) classification (1980). Their distribution by ILO categories 1, 2, and 3, after excluding those with confounding diagnoses for pneumoconiosis, was 30, 10, and 2 cases, respectively. ILO category was related to age, duration of current employment, and cumulative respirable dust and quartz levels, as well as to decrement in ventilatory function.

Challenges and opportunities for using administrative data to explore changes in health status: a study of the closure of the Newfoundland cod fishery.

The closure of the cod fishery in Newfoundland and Labrador has had dramatic social and economic impacts on fishing communities in the province. Following a limited closure in 1992, a more extensive closure followed in 1994, which is still in force today, although income support provided to displaced fishery workers ended in 1999. A population-based study was conducted in 2004/2005 using 7 different sources of administrative and survey data to investigate a range of social, demographic, and health changes in fishing communities affected by the closure of the cod fishery from the period 1991 to 2001. Findings of this study extend our understanding of the impact of the fishing moratorium in Newfoundland. This article also presents both the challenges to and opportunities for using administrative and survey data to explore the impact of the fishery closure on the health and well-being of Newfoundland fishing communities. One of the most significant challenges to using administrative and survey databases was the inconsistencies in how communities were identified across the various databases. Although not without limitations, administrative data is a cost-effective means to explore the impact of socioeconomic change on a populations health status.

G7 Project Promoting Heart Health

In cardiovascular disease (CVD), as in other chronic and acute diseases, one important challenge is to integrate lessons learned from previous intervention experiences, to improve future primary, secondary and tertiary prevention interventions. The purpose of the G7 Project Promoting Heart Health is to establish, maintain, and evaluate a telematics database for the timely dissemination through the INTERNET, of knowledge and experience gained from the implementation of heart health interventions in a wide variety of contexts and settings across G7 countries. Others who wish to implement similar interventions in different contexts and settings can therefore build upon successes and failures from previous implementation experiences.
