- Objective: To identify the dietary, lifestyle and socio-economic factors associated with the intake of whole grains (WG) in Norway, Sweden and Denmark.Design: A cross-sectional study.Setting: Subsample of the Scandinavian cohort ‘HELGA’ consisting of three prospective cohorts: The Norwegian Women and Cancer Study; The Northern Sweden Health and Disease Study; and the Danish Diet, Cancer and Health Study.Subjects: A total of 8702 men and women aged 30–65 years. Dietary data are from one 24 h dietary recall and data on socio-economic status and lifestyle factors including anthropometric values are from the baseline collection of data.Results: Vegetables, fruits, dairy products, fish and shellfish, coffee, tea and margarine were directly associated with the intake of WG, whereas red meat, white bread, alcohol and cakes and biscuits were inversely associated. Smoking and BMI were consistently inversely associated with the intake of WG. Furthermore, length of education was directly associated with the intake of WG among women.Conclusions: The intake of WG was found to be directly associated with healthy diet, lifestyle and socio-economic factors and inversely associated with less healthy factors, suggesting that these factors are important for consideration as potential confounders when studying WG intake and disease associations.

Long-term stability of the alcohol consumption biomarker phosphatidylethanol in erythrocytes at-80 degrees C
- 2019

- Phosphatidylethanol (PEth) is a recently introduced biomarker with high specificity, high sensitivity, and response correlating with alcohol consumption. It has the potential to be a valuable biomarker in population studies on the health effects of alcohol, however its stability in long-term stored blood is not known. We used LCMS/MS to assess the stability of PEth-16:0/18:1 in blood samples (packed erythrocytes) that were stored between 1 and 19 years at -80 degrees C in a biobank from a large population survey. The participants answered a lifestyle questionnaire that included questions on alcohol consumption. For analysis, we selected blood samples from seven homogenous ethanol consumption cohorts collected at intervals from 1997 to 2015. Despite the narrow stated alcohol consumption range, 10-15 g/day, there were large differences in PEth values between individuals in the cohorts, from below the limit of detection of 0.005 mu mol/L to 1.40 mu mol/L. The median was 0.08 mu mol/L. Neither generalized linear modeling, nor principal component analysis revealed a statistically significant association between time of storage and PEth levels. The PEth results indicate that the participants had, on average, under-reported their alcohol consumption several-fold. The findings suggest that PEth in blood has a sufficient long-term stability for use as an alcohol biomarker in prospective case-control studies. Analysis of blood stored in biobanks could significantly improve the validity of assessments exploring the health effects of alcohol.

- BACKGROUND/OJBECTIVES: Alkylresorcinols (AR) have been suggested as specific biomarkers of whole-grain (WG) and bran intake from wheat and rye. Before using plasma AR as biomarkers in prospective cohort studies, the long-term reproducibility needs to be determined in order to judge how well a single plasma sample reflects the long-term concentration. The objective was therefore to estimate the reproducibility of plasma AR concentrations over 0.1-3.9 years. SUBJECTS/METHODS:The concentrations of AR homologues were analysed in plasma samples, drawn >8 h since last meal, 0.1-3.9 years apart (mean similar to 2 years) in 74 participants in the Swedish prospective Vasterbotten Intervention Project cohort. Reproducibility was estimated by calculating the intra class correlation coefficient (ICC). RESULTS: Fasting plasma AR concentrations were similar between the first and second measurements. The ICC for total AR was 0.54 (95% confidence interval (CI) = 0.38-0.69] overall, 0.34 (95% CI = 0.13-0.64) for men and 0.73 (95% CI = 0.56-0.85) for women, respectively. Somewhat higher ICCs were obtained for shorter AR homologues. CONCLUSION: In summary, the reproducibility of plasma AR over 0.1-3.9 years was high for women and moderate for men within this population. Together with previous data showing high validity of plasma AR as biomarkers of wheat and rye in different populations, the current finding suggest that this biomarker is stable over a long-time period and is therefore probably useful for assessment of long-term WG intake in populations with a wide intake range and a frequent intake.

Tidskriftsartikel (refereegranskat)abstract
- Since 1985 a 10 year prevention programme aiming to reduce cardiovascular diseases (CVD) has been running in the county of Västerbotten in Northern Sweden. The project started in Norsjö. The present investigation is a study on dietary intake, medical CVD risk factors and dental caries in five cross-sectional groups of 15-year-olds during 5 years (1987-1991) of the "Norsjö project". Most of the measured medical and dietary variables followed a similar trend, i.e. a positive trend during the first 3 years (1987-1989) and in the last 2 years (1990-1991) the averages returned towards baseline values. Dental caries prevalence followed a similar trend. Parental educational level did not have a major influence on diet or medical CVD risk factors, but higher caries scores were noted in adolescents with parents with "low" education compared with adolescents where the parents had higher educational levels. The results from the study also point to the fact that dental caries prevalence together with body mass index may indicate adolescents with CVD risk factors at unfavourable levels. Dietary counselling by dental personnel to adolescents with high caries and moderate obesity can be of advantage in reducing caries risk, as well as risk for development of CVD at higher ages.

- In an earlier study on a selected group of adolescents with high caries prevalence we found dietary habits that resembled those considered to promote the development of atherosclerosis. In the present study we have compared DMF-score with factors traditionally associated with the risk for development cardiovascular diseases (CVD). All 15-yr-olds living in an urban community in Northern Sweden 1987-1989 were included. Medical variables related to the risk of developing CVD were evaluated in groups of adolescents with various levels of manifest caries expressed as decayed and filled surfaces (DFS). The proportion of individuals with no medical risk factor at an unfavorable level was significantly higher in a caries free than in a high-caries (DFS > or = 9) group. Adolescents with two or more medical factors reaching unfavorable levels had a significantly higher caries score than the group with no factor at unfavorable level. A significant positive correlation was found for the whole group between DFS-score and relative body weight (body mass index) in an univariate correlation test as well as multiple linear regression analysis. The hypothesis that high caries score can be an indicator for unfavorable levels of traditional risk factors for CVD is not contradicted by the results in the present study but supported by the observed covariation with BMI. We therefore suggest that dietary counseling to adolescents with a high caries score in combination with a moderate obesity can be of advantage in reducing the caries risk as well as the risk for development of CVD at higher ages.

- Consumption of fruits and vegetables is associated with a lower overall mortality. The aim of this study was to identify causes of death through which this association is established. More than 450,000 participants from the European Prospective Investigation into Cancer and Nutrition study were included, of which 25,682 were reported deceased after 13 years of follow-up. Information on lifestyle, diet and vital status was collected through questionnaires and population registries. Hazard ratios (HR) with 95 % confidence intervals (95 % CI) for death from specific causes were calculated from Cox regression models, adjusted for potential confounders. Participants reporting consumption of more than 569 g/day of fruits and vegetables had lower risks of death from diseases of the circulatory (HR for upper fourth 0.85, 95 % CI 0.77-0.93), respiratory (HR for upper fourth 0.73, 95 % CI 0.59-0.91) and digestive system (HR for upper fourth 0.60, 95 % CI 0.46-0.79) when compared with participants consuming less than 249 g/day. In contrast, a positive association with death from diseases of the nervous system was observed. Inverse associations were generally observed for vegetable, but not for fruit consumption. Associations were more pronounced for raw vegetable consumption, when compared with cooked vegetable consumption. Raw vegetable consumption was additionally inversely associated with death from neoplasms and mental and behavioral disorders. The lower risk of death associated with a higher consumption of fruits and vegetables may be derived from inverse associations with diseases of the circulatory, respiratory and digestive system, and may depend on the preparation of vegetables and lifestyle factors. © 2014 Springer Science+Business Media Dordrecht.

- Carotenoids and vitamins A, C and E are possibly associated with a reduced colorectal cancer (CRC) risk through antioxidative properties. The association of prediagnostic plasma concentrations and dietary consumption of carotenoids and vitamins A, C and E with the risk of colon and rectal cancer was examined in this case-control study, nested within the European Prospective Investigation into Cancer and Nutrition study. Plasma concentrations of carotenoids (α- and β-carotene, canthaxanthin, β-cryptoxanthin, lutein, lycopene, zeaxanthin) and vitamins A (retinol), C and E (α-, β- and γ- and δ-tocopherol) and dietary consumption of β-carotene and vitamins A, C and E were determined in 898 colon cancer cases, 501 rectal cancer cases and 1,399 matched controls. Multivariable conditional logistic regression models were performed to estimate incidence rate ratios (IRR) and corresponding 95% confidence intervals (CIs). An association was observed between higher prediagnostic plasma retinol concentration and a lower risk of colon cancer (IRR for highest quartile = 0.63, 95% CI: 0.46, 0.87, p for trend = 0.01), most notably proximal colon cancer (IRR for highest quartile = 0.46, 95% CI: 0.27, 0.77, p for trend = 0.01). Additionally, inverse associations for dietary β-carotene and dietary vitamins C and E with (distal) colon cancer were observed. Although other associations were suggested, there seems little evidence for a role of these selected compounds in preventing CRC through their antioxidative properties.

- Candida albicans and Torulopsis glabrata are the most prevalent yeasts in humans. The majority harbor C. albicans in the oral cavity, but only a few develop oral candidiasis. We have sought a possible relationship between indigenous salivary constituents, including antimicrobial and nutritive factors, and the growth rate and/or viability of inoculated fungi in glucose-supplemented sterilized saliva. Stimulated whole saliva was collected from 30 healthy donors. Saliva samples were sterilized, supplemented with glucose and inoculated with C. albicans or T glabrata. After incubation of the inoculates for 20 h, the number of viable cells were counted. All saliva samples were analyzed for different indigenous salivary components and Candida before as well as after sterilization. Besides a 4% reduction in calcium (Ca2+) and thiocyanate (SCN-) concentrations, sterilization did not affect the concentrations of saliva electrolytes, but the proteins were significantly reduced (19-85%). Indigenous candidal carriage (n=19) correlated with neither the growth of inoculated fungi nor any of the analyzed components in saliva. The growth of C. albicans and T. glabrata was similar at pH 5 but, at pH 6, C. albicans had a remarkably slower growth rate than T. glabrata. Statistical analysis showed that the 5-h growth of C. albicans at pH 5 was associated with water and electrolyte secretion, whereas the growth after 20 h was associated with variations in protein-glycoprotein content. The growth of T. glabrata was not related to variations in the salivary variables analyzed.

- Saliva is frequently used as a diagnostic fluid and several collection devices have been developed. OBJECTIVE: The aim of the present study was to investigate the validity and reliability of two types of Salivette collection kits (non-covered cotton roll and polypropylene covered polyether roll) relative to conventional collection of saliva using paraffin wax chewing stimulation. MATERIALS AND METHODS: Whole saliva samples were collected from 16 healthy volunteers. Following a cross-over design saliva was collected in a standardized way. The flow rate was determined and saliva samples were analyzed for pH, buffer capacity, electrolytes and protein/glycoprotein content. RESULTS: We find that Salivette methods do not allow evaluation of flow rate. pH was unaffected but buffer capacity was lower in Salivette collected than in paraffin wax-stimulated saliva. The non-covered cotton rolls reduced the content of Na+, K+, Cl-, as well as glycoprotein markers (hexosamines, fucose, sialic acid), lysozyme, lactoferrin, salivary- and myeloperoxidase but increased the concentrations of Ca2+, PO4(3)- and SCN-. Polypropylene covered polyether rolls affected saliva composition less than the non-covered cotton rolls. Thus, SCN- and sIgA concentrations were higher and lysozyme activity lower in the former (covered roll) saliva than in paraffin wax saliva. The reliability of the Salivette kits was good. CONCLUSION: We conclude that the Salivette method generates data significantly different from conventional paraffin wax-stimulated saliva such as buffer capacity and several electrolytes and organic components. Care should be taken in interpreting the results when such methods are employed.

- Actinomyces spp. exhibit type 1 fimbria-mediated adhesion to salivary acidic proline-rich proteins (PRPs) and statherin ligands. Actinomyces spp. with different animal and tissue origins belong to three major adhesion types as relates to ligand specificity and type 1 fimbria genes. (i) In preferential acidic-PRP binding, strains of Actinomyces naeslundii genospecies 1 and 2 from human and monkey mouths displayed at least three ligand specificities characterized by preferential acidic-PRP binding. Slot blot DNA hybridization showed seven highly conserved type 1 fimbria genes (orf1- to -6 and fimP) in genospecies 1 and 2 strains, except that orf5 and orf3 were divergent in genospecies 1. (ii) In preferential statherin binding, oral Actinomyces viscosus strains of rat and hamster origin (and strain 19246 from a human case of actinomycosis) bound statherin preferentially. DNA hybridization and characterization of the type 1 fimbria genes from strain 19246 revealed a homologous gene cluster of four open reading frames (orfA to -C and fimP). Bioinformatics suggested sortase (orfB, orf4, and part of orf5), prepilin peptidase (orfC and orf6), fimbria subunit (fimP), and usher- and autotransporter-like (orfA and orf1 to -3) functions. Those gene regions corresponding to orf3 and orf5 were divergent, those corresponding to orf2, orf1, and fimP were moderately conserved, and those corresponding to orf4 and orf6 were highly conserved. Restriction fragment length polymorphism analyses using a fimP probe separated human and monkey and rat and hamster strains into phylogenetically different groups. (iii) In statherin-specific binding, strains of A. naeslundii genospecies 1 from septic and other human infections displayed a low-avidity binding to statherin. Only the orf4 and orf6 gene regions were highly conserved. Finally, rat saliva devoid of statherin bound bacterial strains avidly irrespective of ligand specificity, and specific antisera detected either type 1, type 2, or both types of fimbria on the investigated Actinomyces strains.
