Anatomists are exposed to a wide range of solvents, stains, and preservatives used to prepare biologic specimens. One fixative, formaldehyde, has recently been shown to cause nasal cancer in laboratory rodents. A retrospective cohort study was conducted to assess whether anatomists have an increased risk of mortality from cancer, particularly from cancers(More)
Some, but not all, epidemiological studies have suggested that dichlorodiphenyltrichloroethane (DDT) may play a role in the development of breast cancer. These investigations have been conducted in countries where this substance has been banned for at least 20 years. We conducted a study in Mexico, a country in which DDT is still being used to control(More)
Information on the association between exposure to beta-hexachlorocyclohexane (beta-HCH), hexachlorobenzene (HCB) or polychlorinated biphenyls (PCBs) and the incidence of breast cancer is inconclusive. However, exposure to such compounds is a public health concern in Mexico and is subject to recent regulation. Serum levels of beta-HCH, HCB and PCBs were(More)
We studied the relation between self-reported physical activity and cancer in the first National Health and Nutrition Examination Survey (NHANES I) cohort, originally examined between 1971-75, and followed prospectively through the Epidemiologic Follow-up Study (NHEFS), conducted between 1982-84. Among 5,138 men and 7,407 women 25-74 years old, for(More)
Dichlorodiphenyldichloroethane (DDE) adipose tissue level has been regarded as a preferred indicator of accumulated human exposure to DDT; however, blood sera are more feasible to obtain and analyze than adipose tissue samples. Inconsistent and scarce information exists in relation to the adipose tissue/serum DDE ratio. As a part of a hospital-based(More)
This study sought to assess whether the health of recent immigrants to Canada has changed in the past decade. Using the Canadian Community Health Survey this study examined changes in self-perceived health of 5,757 recent immigrants over a decade. Multivariable ordinal logistic regressions were conducted to calculate odds ratios (OR) and 95 % confidence(More)
This study explored trends of sexual assault and associated risk factors within a cohort of young Aboriginal women who used drugs in Vancouver and Prince George, Canada, between 2003 and 2010. Results demonstrated no change in the trend of sexual assault over time; however, odds of sexual assault were significantly higher for women who had at least one(More)
BACKGROUND Elevated body mass index (BMI) and arsenic are both associated with cancer and with non-malignant lung disease. Using a unique exposure situation in Northern Chile with data on lifetime arsenic exposure, we previously identified the first evidence of an interaction between arsenic and BMI for the development of lung cancer. OBJECTIVES We(More)
BACKGROUND Policing has profound health implications for people who use illicit drugs. Among Aboriginal communities, distrust of police is common, due partly to legacies of colonial policing. In response to the paucity of research among Aboriginal people who use drugs, this paper aims to: (1) Describe the policing experiences of young Aboriginal people who(More)
The risk of leukemia among farmers and dairy farmers in particular was studied with the use of mortality records from Wisconsin, 1968-76. A comparison of occupation as noted on the death certificate for 1,499 cases and a like number of matched controls revealed a slight [odds ratio (OR) = 1.10], but statistically nonsignificant, excess risk of leukemia(More)
