The death toll of the epidemic of chronic kidney disease of nontraditional origin (CKDnt) in Mesoamerica runs into the tens of thousands, affecting mostly young men. There is no consensus on the etiology. Anecdotal evidence from the 1990s pointed to work in sugarcane; pesticides and heat stress were suspected. Subsequent population-based surveys su...
Article
Full-text available
Objectives The lack of a common definition for precarious employment (PE) severely hampers the comparison of studies within and between countries, consequently reducing the applicability of research findings. We carried out a systematic review to summarize how PE has been conceptualized and implemented in research and identify the construct's dimen...
Article
Incorrect analysis results that are close to expected might not be recognized in scientific studies or routine patient care. In two field studies we obtained unexpected results in a large number of samples. The present study aimed to identify the source of error in the samples from these studies and to validate a method to obtain correct results. P...

Article
In this information age we are increasingly dependent on having adequate and timely data appropriate to inform decisions and action. In fact, there is good reason to worry about the old adage that “if it is not counted it didn't happen”. This concern has prompted focus on the need to modernise occupational health surveillance.1–4 Fundamental to eff...

We appreciate Ventres' observations and share his goal to reduce CKD incidence "by occupational, environmental, and health-related reforms that make this work [agricultural labor] more humane." In our summary of the workshop on the Mesoamerican nephropathy (MeN) in San José, Costa Rica, November 2012, we also noted the need for a broad understandin...
Conference Paper
Background: According to the Survey of Occupational Injuries and Illnesses, the rate of musculoskeletal disorders (MSD) among Massachusetts hospital workers (1.3 cases/100 FTEs) is almost twice the national rate. Previous studies show that safe patient handling (SPH) programs effectively reduce patient handling injuries and MSDs among direct care s...
Conference Paper
Background: Epidemics of chronic kidney disease of unknown etiology (CKDu) occur in multiple populations of Mesoamerica. CKDu appears disproportionally among young male sugarcane workers and has completely overwhelmed the healthcare systems in some areas. Similar phenomena have been reported in agricultural populations in Sri Lanka and India. Despi...
Conference Paper
Background: Excessive heat exposure in workplaces is a well known occupational health hazard. In the USA workplace heat deaths occur primarily among immigrant agricultural workers. Heat waves in Europe and regular heat conditions in tropical countries also cause heat stroke among manual workers. Climate change will make this situation worse, challe...

Adolescent employment is commonly valued in the United States for its ability to promote youths’ positive psychosocial development. Empirical research, however, suggests the extent to which youth reap such benefits from work is largely a function of work’s quality. This study investigated adolescent work quality by examining the extent to which cha...

Full-text available
Injuries are not accidents, so in public health we search for their causes to improve prevention. The best of these efforts seek to identify root causes, avoiding the more limited approach that stops at the level of "the human" responsible for "the error." Attention is directed to the variety of systems-related determinants that permit or promote h...
Article
Full-text available
Developing nations carry a substantial portion of the global burden of injury, but without reliable injury surveillance, there is no way to characterize or prioritize the causes of work-related injury for prevention. Injury data from 52 treatment sites in the Xuan Tien Commune, Vietnam with over 10,000 inhabitants were collected between January 1 a...
Article
Full-text available
We explored the impact on work-related injuries of workers splitting time between industry and agriculture, a common situation in developing countries. In 2005, we administered a cross-sectional survey to 2615 households of Xuan Tien, a developing rural community of Vietnam, regarding self-reported injuries and hours worked for 1 year. We defined g...
