Implementation And Evaluation Of An Analytical Method For A Novel Derivatizing Agent To Measure 4,4'-Methylene Diphenyl Diisocyanate Atmospheres, Silvia Puscasu, Simon Aubin, Mark Spence, Sébastien Gagné

Études primaires

Accurate measurement of 4,4'-methylene diphenyl diisocyanate (MDI) atmospheres is a challenge since the molecule is both chemically reactive and likely to be present in aerosol form when heated and sprayed because of its low vapor pressure. Meeting this challenge requires optimizing both the sampling device used and the derivatization agent employed to stabilize the isocyanate functional group. This study describes the use of a novel derivatization reagent for isocyanate sampling to address the challenge of MDI aerosol exposure sampling. Like most conventional derivatizing agents for isocyanates, 1,8-diaminonapthalene (DAN) reacts with isocyanate functional groups to form a urea. However, unlike other …

The “Burnout” Construct: An Inhibitor Of Public Health Action?, Bianchi Renzo, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

The prevention and treatment of the “burnout syndrome” within the critical care community is an important objective of the Moss et al. Burnout in the occupational area is based on the idea that burnout is especially common in individuals who care for critically ill patients. We think that the authors’ observations and recommendations are diminished by the fact that studies of burnout’s prevalence are methodologically problematic. The current definition and use of the burnout construct may in fact be detrimental to public health decision making.

Thinking About Work At Home: Implications For Safety At Work, Frankie Guros

Dissertations and Theses

Safety at work is of the utmost importance to employees and the organizations they work for, and as such, it is a central issue for occupational health psychology. Although dramatic decreases in the number of worker injuries and fatalities have been observed over the last several decades, safety remains a principal concern for organizations. This is especially true in occupations in which employees face serious threats to their personal safety, such as correctional officers (COs). While a number of studies have identified workplace factors that contribute to worker safety, few have attempted to draw a link between employee nonwork experiences …

Rapports de recherche scientifique

L’asthme professionnel est un type d’asthme causé par un agent présent dans les milieux de travail. Le type principal d’asthme professionnel est celui qui est causé par le développement d’une « allergie » à certains agents présents dans le milieu de travail. La mise en évidence de cette « allergie » est une étape essentielle de l’investigation clinique ou de l’élaboration de programmes de prévention. En effet, la maladie ne peut, par définition, être présente s’il n’existe pas d’allergie démontrée. Dans l’état actuel des connaissances, l’allergie, celle de type immédiate associée à une sensibilisation avec la formation d’immunoglobulines de type …

Leisure-Time Physical Activity, Falls, And Fall Injuries In Middle-Aged Adults., Alberto J. Caban-Martinez, Theodore K. Courtney, Wen-Ruey Chang, David A. Lombardi, Melissa J. Perry, Jeffrey N. Katz, David C. Christiani, Santosh K. Verma

Environmental and Occupational Health Faculty Publications

Introduction

Although exercise and strength training have been shown to be protective against falls in older adults (aged 65 years and older), evidence for the role of leisure-time physical activity (LTPA) in the prevention of falls and resulting injuries in middle-aged adults (aged 45–64 years) is lacking. In the present study, we investigate the association between self-reported engagement in LTPA and the frequency of falls and fall-related injuries among middle-aged and older adults, while controlling for key sociodemographic and health characteristics.
