For a cohort of 1189 male German former herbicide and insecticide workers with exposure to polychlorinated dibenzo-p-dioxins and -furans (PCDD/F), we report an extended standardized mortality ratio (SMR) analysis based on a new quantitative exposure index. This index characterizes the cumulative lifetime exposure by integrating the estimated concentration(More)
We consider a cohort of 1189 male German factory workers (production period 1952-1984) who produced phenoxy herbicides and were exposed to dioxins. Follow-up until the end of 1992 yielded a significantly increased standardized mortality ratio (SMR) for total cancer (SMR 141; 95% confidence interval 117-168). 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD)(More)
Gliomas are the most frequent primary brain tumors in humans. Many studies have been carried out on their etiology; however, the only confirmed risk factors are hereditary predisposing conditions and high dose of ionizing radiation. Recently, human cytomegalovirus (HCMV) gene products and nucleic acids were reported to be present in all of 27 glioma samples(More)
Cancer-related fatigue (CRF) is one of the most common and distressing side effects of cancer and its treatment. During and after radiotherapy breast cancer patients often suffer from CRF which frequently impairs quality of life (QoL). Despite the high prevalence of CRF in breast cancer patients and the severe impact on the physical and emotional(More)
OBJECTIVE Fatigue is among the most distressing symptoms across the breast cancer continuum. However, little is known about the factors contributing to long-term persisting fatigue. Therefore, we explored determinants of long-term physical, affective, and cognitive fatigue in a prospective cohort of breast cancer patients. METHODS Breast cancer patients(More)
Physical activity plays an important role in colorectal cancer and accelerometry is more frequently used to measure physical activity. The aim of this study was to evaluate feasibility of physical activity measurement by accelerometry in colorectal cancer patients under free-living conditions at 6, 12 and 24 months after surgery, to evaluate the appropriate(More)
OBJECTIVES Physical activity (PA) is increasingly discussed as a means to achieve both physical and psychological benefits for breast cancer patients and survivors. However, little is known about activity-specific PA behavior following diagnosis. Our objectives were to describe sports and active transportation in the course of breast cancer and to identify(More)
Over the past years knowledge about benefits of physical activity after cancer is evolving from randomized exercise intervention trials. However, it has been argued that results may be biased by selective participation. Therefore, we investigated factors influencing participation in a randomized exercise intervention trial for breast cancer patients.(More)
Fatigue is a major burden for breast cancer patients undergoing adjuvant therapy. Yet, its pathophysiology is still not well understood. Hypothesized mechanisms include dysregulations in the hypothalamic-pituitary-adrenal (HPA) axis, which may be reflected in alterations in the diurnal cortisol patterns. However, studies on the association between cortisol(More)
BACKGROUND The aim of this study is to review accelerometer wear methods and correlations between accelerometry and physical activity questionnaire data, depending on participant characteristics. METHODS We included 57 articles about physical activity measurement by accelerometry and questionnaires. Criteria were to have at least 100 participants of at(More)
