The authors examined the associations between dietary factors and the risk of duodenal ulcer in a prospective cohort of 47,806 men, aged 40-75 years, who were free of diagnosed gastric or duodenal ulcer or cancer. During 6 years of follow-up, they documented 138 newly diagnosed cases of duodenal ulcer. They found little evidence for an important effect of fat, type of fat, or protein intake. Hi...

BACKGROUND AND AIM The role of dietary glycemic index (GI) and glycemic load (GL) in coronary heart disease (CHD) is unclear. Our aim was to study the association between the dietary GI and GL and the risk of acute myocardial infarction (AMI). METHODS AND RESULTS The study population consisted of 1981 Finnish men from the prospective population-based Kuopio Ischaemic Heart Disease Risk Factor...

BACKGROUND Dietary glycemic load (GL) and glycemic index (GI) in relation to cardiovascular disease have been investigated in a few prospective studies with inconsistent results, particularly in men. The present EPICOR study investigated the association of GI and GL with coronary heart disease (CHD) in a large and heterogeneous cohort of Italian men and women originally recruited to the Europea...

OBJECTIVE To the best of our knowledge, the association of insulin resistance (IR) with chronic kidney disease (CKD) has not been well studied in normal-weight individuals. The aim of this study is to examine whether IR is associated with CKD in non-diabetic subjects with normal weight. We also examine whether the presence of obesity modifies the association of IR with CKD. METHODS Data were ...

Much attention has been paid to the relation between diet and breast cancer risk. Because benign breast disease (BBD), particularly atypical hyperplasia (AH), is a marker of increased breast cancer risk, studies of diet and BBD may provide evidence about the effect of diet at an early stage in the process of breast carcinogenesis. We evaluated the relationship between fat, fiber, antioxidant an...

To examine the associations between intakes of calcium, Vitamin D, and dairy foods and the risk of colon cancer, the authors analyzed data from a prospective study of 47,935 US male professionals, 40-75 years of age and free of cancer in 1986. Within this cohort, 203 new cases of colon cancer were documented between 1986 and 1992. After adjusting for age and total energy intake, the authors fou...

BACKGROUND While it is known that a variety of factors (biological, behavioural and interventional) play a major role in the health of individuals and populations, the importance of the role of social determinants is less clear. The effect of social inequality on population-based screening for colorectal cancer (CRC) could limit the value of such programmes. The present study aims to determine ...

BACKGROUND Green tea has shown the role of chemoprevention for cancer. Recently, several studies suggested that green tea intake may have effect on esophageal cancer risk, whereas the results were inconsistent. METHODS We performed a meta-analysis of all English and Chinese language studies of green tea consumption and esophageal cancer risk indexed in Medline, Embase, the Science Citation In...

BACKGROUND Nowadays, nurses play a central role in telephone triage in Dutch out-of-hours primary care. The percentage of calls that is handled through nurse telephone advice alone (NTAA) appears to vary substantially between GP cooperatives. This study aims to explore which determinants are associated with NTAA and with subsequent return consultations to the GP. METHODS For the ten most freq...

BACKGROUND Several epidemiological studies have determined the associations between coffee intake level and skin cancer risk; however, the results were not yet conclusive. Herein, we conducted a systematic review and meta-analysis of the cohort and case-control studies for the association between coffee intake level and malignant melanoma (MM) risk. METHODS Studies were identified through sea...
