OBJECTIVES This case-control study investigated risk factors for campylobacteriosis in a rural population. Exposure to live farm animals was hypothesized to increase the risk for Campylobacter jejuni enteritis. METHODS Incident cases from rural counties reported to the Michigan Department of Community Health and matched controls completed a(More)
To compare the incidence of Campylobacter jejuni enteritis in high- and low-poultry-density counties in Michigan between the years 1992 and 1999, an ecological study was conducted in the state of Michigan. A log-linear model was used to compare yearly, seasonal, age, and gender-specific incidence rates between county groupings. Counties with a high poultry(More)
Phthalates are ubiquitous industrial chemicals that are reported to adversely affect human reproductive outcomes. Divergent effects on semen quality have been reported in a limited number of studies. To assess the possible contribution of regional differences in phthalate exposure to these results, we wished to determine if ambient phthalate exposure of men(More)
BACKGROUND Low-back pain is a common and costly problem. We estimated the effectiveness of a group cognitive behavioural intervention in addition to best practice advice in people with low-back pain in primary care.

Pedal metastases from visceral cancers, while rare, constitute a consideration in the presence of an otherwise unexplained mass in the skin, subcutis, or bones of the foot. Metastatic lesions may be presenting signs of visceral malignant tumors, or may remain occult for years after extirpation of the primary visceral lesion. The presented case depicts(More)
BACKGROUND Occupational and experimental animal studies indicate that exposure to high levels of manganese impairs male fertility, but the effects of ambient manganese in humans are not known. METHODS We measured blood levels of manganese and selenium in 200 infertility clinic clients in a cross-sectional study. Correlations between metals and semen(More)

BACKGROUND Depression is common and is associated with poor outcomes among elderly care-home residents. Exercise is a promising low-risk intervention for depression in this population. We tested the hypothesis that a moderate intensity exercise programme would reduce the burden of depressive symptoms in residents of care homes. METHODS We did a(More)
BACKGROUND Depression is common in residents of Residential and Nursing homes (RNHs). It is usually undetected and often undertreated. Depression is associated with poor outcomes including increased morbidity and mortality. Exercise has potential to improve depression, and has been shown in existing trials to improve outcomes among younger and older people.(More)
