Abstract Extraintestinal manifestations occur rather frequently in inflammatory bowel disease (IBD), e.g. ulcerative colitis (UC) and Crohn's disease (CD). The present paper provides an overview of the epidemiology, clinical characteristics, diagnostic process, and management of rheumatic, metabolic, dermatologic (mucocutaneous), ophthalmologic,(More)
BACKGROUND Health behaviour changes may improve the quality of life and survival among cancer survivors. We prospectively examined changes in health behaviour among and between men with prostate cancer (PC), men with cancers other than PC and cancer-free men. METHODS We analysed data for 20 914 men (50-65 years), 426 with cancer, and 20 488 persons who(More)
Alcohol is a risk factor for postmenopausal breast cancer. One of several proposed mechanisms is that alcohol-related breast cancer is caused by increased sex hormone levels. PPARγ inhibits aromatase transcription in breast adipocytes. We reproduced previously found allele-specific effects of the wildtype Pro-allele of PPARG Pro(12)Ala in alcohol related(More)
Socioeconomic position and lifestyle often affect participation in scientific studies. The authors investigated differences in overall and cause-specific mortality between participants and non-participants in the prospective Danish cohort study "Diet, Cancer and Health" and the association between non-participation and mortality by socioeconomic position. A(More)
BACKGROUND In Denmark, the incidence of breast cancer is higher among women with higher socioeconomic position. We investigated whether differences in exposure to certain risk factors contribute to this gradient, as measured from education, income and occupation. METHODS We conducted a cohort study of 23,111 postmenopausal women aged 50-65 years who were(More)
BACKGROUND Social differences in prostate cancer (PC) incidence and mortality might be related to testing for prostate-specific antigen (PSA). Although routine PSA screening is not recommended in Denmark, testing without clinical indication increased during the past decade. We evaluated associations between socio-demographic or clinical characteristics and(More)
BACKGROUND A breast cancer diagnosis has been suggested as a teachable moment when a woman is more open to making healthier lifestyle changes. Little is known about the health behaviour changes women with breast cancer initiate compared to those made by other women. MATERIAL AND METHODS We examined changes in body mass index (BMI) and tobacco and alcohol(More)
OBJECTIVE To evaluate semen quality and fecundity in a group of men with initially untreated varicocele testis, in comparison with control subjects. PATIENTS, SUBJECTS AND METHODS In a prospective, longitudinal study, 77 men (39 with varicocele and 38 control subjects) were evaluated in 1989 and re-investigated after 8 years. Fifty-seven men (29 with(More)
There is no clear link between obesity and prostate cancer incidence but an association has been reported between obesity and fatal prostate cancer. We report on two prospective cohort analyses on (i) the incidence of prostate cancer in relation to obesity in a cohort of men with no previous cancer, and on (ii) the stage distribution and prostate cancer(More)
Micronutrients may protect against prostate cancer. However, few studies have had high-quality assessment of both dietary and supplemental consumption of micronutrients, rendering possible different source-specific effects difficult to discern. This study evaluates associations between intake of vitamin C, E, folate, and beta-carotene and prostate cancer(More)
