Exposure to aircraft and road traffic noise and associations with heart disease and stroke in six European countries: a cross-sectional study

Abstract: Although a number of studies have found an association between aircraft noise and hypertension, there is a lack of evidence on associations with other cardiovascular disease. For road traffic noise, more studies are available but the extent of possible confounding by air pollution has not been established. This study used data from the Hypertension and Environmental Noise near Airports (HYENA) study. Cross-sectional associations between self-reported ‘heart disease and stroke’ and aircraft noise and road traffic noise were examined using data collected between 2004 and 2006 on 4712 participants (276 cases), who lived near airports in six European countries (UK, Germany, Netherlands, Sweden, Greece, Italy). Data were available to assess potential confounding by NO2 air pollution in a subsample of three countries (UK, Netherlands, Sweden). An association between night-time average aircraft noise and ‘heart disease and stroke’ was found after adjustment for socio-demographic confounders for participants who had lived in the same place for ≥ 20 years (odds ratio (OR): 1.25 (95% confidence interval (CI) 1.03, 1.51) per 10 dB (A)); this association was robust to adjustment for exposure to air pollution in the subsample. 24 hour average road traffic noise exposure was associated with ‘heart disease and stroke’ (OR: 1.19 (95% CI 1.00, 1.41), but adjustment for air pollution in the subsample suggested this may have been due to confounding by air pollution. Statistical assessment (correlations and variance inflation factor) suggested only modest collinearity between noise and NO2 exposures. Exposure to aircraft noise over many years may increase risks of heart disease and stroke, although more studies are needed to establish how much the risks associated with road traffic noise may be explained by air pollution.

Diet, metabolic polymorphisms and dna adducts: the EPIC-Italy cross-sectional study.

Abstract: DNA adducts in peripheral leukocytes are considered a reliable indicator of internal dose exposure to genotoxic agents and, possibly, of cancer risk. We investigated their association with diet and other individual characteristics in healthy adults. The prospective study EPIC-Italy, a section of a larger European project, enrolled 47,749 men and women, aged 35–64 years, in 5 centres: all provided individual information about dietary and life-style habits and a blood sample. In a cross-sectional study, approximately 100 volunteers were randomly selected from each of the three main geographical study areas (Northern, Central and Southern Italy). DNA adducts and four polymorphic metabolic genotypes were determined in peripheral leukocytes by using 32P-postlabelling technique and PCR methods. Among 309 subjects (153 men), 72.8% had detectable levels of DNA adducts (mean: 8.1 ± 0.6 per 109 nucleotides). Strong negative associations emerged with the reported frequency of consumption of fresh fruit and vegetables, olive oil, and the intake of antioxidants. DNA adducts were higher in subjects with GSTT1 null genotype (p = 0.05). Significant differences between study centres emerged in multivariate analyses (mean levels: 11.0, 10.0, 7.2, 6.5 and 5.2 for Florence, Naples, Turin, Varese and Ragusa, respectively). A possible opposite seasonal variation was found according to latitude: adduct levels tended to be lower in winter in Florence and the southern centres, and during summer in the two northern centres. Frequent consumption of fresh fruit and vegetables is associated with reduced levels of DNA adducts, possibly contributing to the role of diet in modulating cancer risk. Int. J.

European guidelines for quality assurance in colorectal cancer screening and diagnosis. First Edition--Executive summary.

Abstract: Multidisciplinary, evidence-based guidelines for quality assurance in colorectal cancer screening and diagnosis have been developed by experts in a project coordinated by the International Agency for Research on Cancer. The full guideline document covers the entire process of population-based screening. It consists of 10 chapters and over 250 recommendations, graded according to the strength of the recommendation and the supporting evidence. The 450-page guidelines and the extensive evidence base have been published by the European Commission. The content of the executive summary is presented here to promote international discussion and collaboration by making the principles and standards recommended in the new EU Guidelines known to a wider professional and scientific community. Following these recommendations has the potential to enhance the control of colorectal cancer through improvement in the quality and effectiveness of screening programmes and services.

Dietary intakes and food sources of phytoestrogens in the European Prospective Investigation into Cancer and Nutrition (EPIC) 24-hour dietary recall cohort

Abstract: BACKGROUND/OBJECTIVES: Phytoestrogens are estradiol-like natural compounds found in plants that have been associated with protective effects against chronic diseases, including some cancers, cardiovascular diseases and osteoporosis. The purpose of this study was to estimate the dietary intake of phytoestrogens, identify their food sources and their association with lifestyle factors in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. SUBJECTS/METHODS: Single 24-hour dietary recalls were collected from 36 037 individuals from 10 European countries, aged 35-74 years using a standardized computerized interview programe (EPIC-Soft). An ad hoc food composition database on phytoestrogens (isoflavones, lignans, coumestans, enterolignans and equol) was compiled using data from available databases, in order to obtain and describe phytoestrogen intakes and their food sources across 27 redefined EPIC centres. RESULTS: Mean total phytoestrogen intake was the highest in the UK health-conscious group (24.9 mg/day in men and 21.1 mg/day in women) whereas lowest in Greece (1.3 mg/day) in men and Spain-Granada (1.0 mg/day) in women. Northern European countries had higher intakes than southern countries. The main phytoestrogen contributors were isoflavones in both UK centres and lignans in the other EPIC cohorts. Age, body mass index, educational level, smoking status and physical activity were related to increased intakes of lignans, enterolignans and equol, but not to total phytoestrogen, isoflavone or coumestan intakes. In the UK cohorts, the major food sources of phytoestrogens were soy products. In the other EPIC cohorts the dietary sources were more distributed, among fruits, vegetables, soy products, cereal products, non-alcoholic and alcoholic beverages. CONCLUSIONS: There was a high variability in the dietary intake of total and phytoestrogen subclasses and their food sources across European regions.
