RESUMEN
Background: Universities are critical in educating tomorrow's citizens and achieving the Sustainable Development Goals of the United Nations Organization. The aim of this study was to investigate the integration of these goals in the curricula of an Italian university. Study design: Cross-sectional study. Methods: In February 2021, as part of the annual Syllabus preparation for each course, the teaching staffs at the University of Udine (Italy) were asked to complete an additional section in which they could indicate up to three Sustainable Development Goals for their courses. Descriptive statistics, Chi-square test and logistic regression were performed to determine whether the professors' sex, age, or department affected the likelihood of mentioning Sustainable Development Goals. Results: In 723 courses, 360/1040 professors 59% male, mean age 53 years (range 30-73), mentioned one (29%), two (23%), or three (31%) Sustainable Development Goals. No Sustainable Development Goals were mentioned in 16% of courses, the majority of which were from the Mathematical, Computer and Physical Sciences Department (58%). The top six Sustainable Development Goals quoted were: Good health and well-being (35%), Responsible consumption and production (22%), Quality education (17%), Industry, innovation and infrastructure (13%), Gender equality (13%), Decent work and economic growth (13%). The least frequently mentioned Goal was Life below water (1%). Women (p<0.0001) and senior professors (p=0.0148) were more likely to consider at least one of the Sustainable Development Goals, while Mathematical, Computer and Physical Sciences Department showed a negative correlation (p<0.0001). Conclusions: Gaps were identified with respect to specific Sustainable Development Goals, but discrepancies between departments may indicate deficits in respondent awareness. A transparent description of the Sustainable Development Goals in courses is recommended, to increase students' and university's engagement in sustainability.

Background: The fight against fake news, mainly spread through Internet, is a major public health issue, even among undergraduate students. This study aims to evaluate the effectiveness of a website promoted by the Italian Federation of the Provincial Orders of the Medical Doctors as a first aid communication kit for health topics. Study design: Pre-post study using a web-based survey, conducted in April-May 2019 on Medical students and October-November 2020 on Communication Sciences students at the University of Florence (Italy). Methods. Undergraduate students of both schools were exposed to the use of the "dottoremaeveroche" website. Primary and secondary outcomes measures: the Italian-electronic Health Literacy Scale self-assessment tool was used to examine subjects' electronic Health literacy, and source quality. All responses were rated on a 5-point Likert scale. Changing in perception of abilities were examined using the Wilcoxon test. Results: The 362 participants felt moderately confident in electronic Health Literacy, with an initial Italian-electronic Health Literacy Scale overall mean score of 3.6±0.7 for medical and 3.2±0.8 for communication students. Medical students had a good idea of how to find helpful sources (3.9±0.8) and communication students felt confident in recognizing their quality (3.5±1.0). In contrast, their confidence in using Web information to make health decisions was low (medical: 2.9±1.1; communication: 2.8±1.1). All items improved significantly after "dottoremaeveroche" use (p<.001), with the overall mean score of Italian-electronic Health Literacy Scale increasing to 4.3±0.6 for medical and 4.1±0.8 for communication students. Conclusions: Low electronic health literacy levels can affect public health efforts, as seen during the COVID-19 pandemic. The effectiveness of "dottoremaeveroche" among students showed the usefulness of online educational interventions that, if further implemented, could help combat the spread of infodemic.

BACKGROUND: Malnutrition in Intensive Care Unit patients has been associated with worse clinical outcomes such as mortality and length of stay (LOS) in Intensive Care Unit (ICU), and nutritional status of Intensive Care Unit patients in particular seemed to be a significant predictor of mortality. Promptness of clinical nutrition administration is a key of nutritional support whenever volitional intake is unfeasible. Early enteral nutrition is associated with better clinical outcomes (reduced complications, LOS in ICU and in Hospital). The aim of this study is to investigate the nutrition therapy management in a large Academic Hospital, evaluating its effects on mortality and LOS in ICU and in the Hospital. STUDY DESIGN: Data were collected retrospectively from clinical records. Six physicians were trained on the data collection protocol and they reviewed every clinical record of patients included in the survey. METHODS: Data of 426 patients admitted to ICUs between November 2016, 1st and April 2017, 30th were collected. A multivariate logistic adjusted regression, with backward variables selection method, was performed in order to identify predictors of enteral and parenteral nutrition conducted within 48 hours after admission to the ICU. The relation between medical nutrition therapy, mortality and LOS in ICU and in the Hospital were also evaluated. RESULTS: Patients were given prompt parenteral and enteral nutrition in 25.12% and 27.46% of cases, respectively. No association was found between medical nutrition therapy and ICU or hospital mortality. Predictors of early enteral nutrition were type of admission and surgery before admission; early parenteral nutrition predictors were gender, ICU (A vs B), impaired immunity status and Central Venous Catheter presence at admission. CONCLUSIONS: Our study stresses the need of monitoring nutrition prescribing behaviors in acute hospitals in order to better set up tailored interventions to standardize clinicians' practices and to focus on specific training targets.

BACKGROUND: A few papers have considered reproducibility of a posteriori dietary patterns across populations, as well as pattern associations with head and neck cancer risk when multiple populations are available. METHODS: We used individual-level pooled data from seven case-control studies (3844 cases; 6824 controls) participating in the International Head and Neck Cancer Epidemiology consortium. We simultaneously derived shared and study-specific a posteriori patterns with a novel approach called multi-study factor analysis applied to 23 nutrients. We derived odds ratios (ORs) and 95% confidence intervals (CIs) for cancers of the oral cavity and pharynx combined, and larynx, from logistic regression models. RESULTS: We identified three shared patterns that were reproducible across studies (75% variance explained): the Antioxidant vitamins and fiber (OR = 0.57, 95% CI = 0.41, 0.78, highest versus lowest score quintile) and the Fats (OR = 0.80, 95% CI = 0.67, 0.95) patterns were inversely associated with oral and pharyngeal cancer risk. The Animal products and cereals (OR = 1.5, 95% CI = 1.1, 2.1) and the Fats (OR = 1.8, 95% CI = 1.4, 2.3) patterns were positively associated with laryngeal cancer risk, whereas a linear inverse trend in laryngeal cancer risk was evident for the Antioxidant vitamins and fiber pattern. We also identified four additional study-specific patterns, one for each of the four US studies examined. We named them all as Dairy products and breakfast cereals, and two were associated with oral and pharyngeal cancer risk. CONCLUSION: Multi-study factor analysis provides insight into pattern reproducibility and supports previous evidence on cross-country reproducibility of dietary patterns and on their association with head and neck cancer risk.

BACKGROUND: Evidence for the possible effect of vitamin E on head and neck cancers (HNCs) is limited. METHODS: We used individual-level pooled data from 10 case-control studies (5959 cases and 12 248 controls) participating in the International Head and Neck Cancer Epidemiology (INHANCE) consortium to assess the association between vitamin E intake from natural sources and cancer of the oral cavity/pharynx and larynx. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression models applied to quintile categories of non-alcohol energy-adjusted vitamin E intake. RESULTS: Intake of vitamin E was inversely related to oral/pharyngeal cancer (OR for the fifth vs the first quintile category=0.59, 95% CI: 0.49-0.71; P for trend <0.001) and to laryngeal cancer (OR=0.67, 95% CI: 0.54-0.83, P for trend <0.001). There was, however, appreciable heterogeneity of the estimated effect across studies for oral/pharyngeal cancer. Inverse associations were generally observed for the anatomical subsites of oral and pharyngeal cancer and within covariate strata for both sites. CONCLUSION: Our findings suggest that greater vitamin E intake from foods may lower HNC risk, although we were not able to explain the heterogeneity observed across studies or rule out certain sources of bias.

BACKGROUND AND AIMS: Oxidative processes have been related to atherosclerosis, but there is scanty information on the role of dietary antioxidants in the prevention of acute myocardial infarction (AMI). METHODS AND RESULTS: The relationship between non-enzymatic antioxidant capacity (NEAC) and the risk of nonfatal AMI was investigated in a case-control study conducted in Milan, Italy, between 1995 and 2003. Cases were 760 patients below 75 years with a first episode of AMI and controls were 682 patients admitted to hospitals for acute conditions, who completed an interviewer-administered food frequency questionnaire, tested for validity and reproducibility. NEAC (excluding coffee) was measured using Italian food composition tables in terms of ferric reducing-antioxidant power (FRAP), Trolox equivalent antioxidant capacity (TEAC) and total radical-trapping antioxidant parameter (TRAP). The odds ratios (OR) of AMI, and the corresponding 95% confidence intervals (CI), were obtained by multiple logistic regression models including terms for main risk factors of AMI and total energy intake. NEAC was inversely related with the risk of AMI. The ORs for the highest quintile compared with the lowest one were 0.41 (95% CI, 0.27-0.63) for FRAP, 0.42 (95% CI, 0.27-0.65) for TEAC and 0.41 (95% CI, 0.27-0.62) for TRAP, with significant trends in risk. The inverse relationship was apparently stronger in women and in subjects aged ≥ 60 years. CONCLUSIONS: Our results support a favorable role of dietary NEAC in the prevention of AMI, and encourage a high consumption of fruit and vegetables and a moderate consumption of wine and whole cereals.

BACKGROUND: Because of their antioxidant and antimutagenic properties, flavonoids may reduce cancer risk. Some flavonoids have antiestrogenic effects that can inhibit the growth and proliferation of endometrial cancer cells. METHODS: In order to examine the relation between dietary flavonoids and endometrial cancer, we analysed data from an Italian case-control study including 454 incident, histologically confirmed endometrial cancers and 908 hospital-based controls. Information was collected through a validated food-frequency questionnaire. We applied data on food and beverage composition to estimate the intake of flavanols, flavanones, flavonols, anthocyanidins, flavones, isoflavones, and proanthocyanidins. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated from multiple logistic regression models conditioned on age and study centre and adjusted for major confounding factors. RESULTS: Women in the highest quartile category of proanthocyanidins with ≥3 mers vs the first three quartile categories had an OR for endometrial cancer of 0.66 (95% CI=0.48-0.89). For no other class of flavonoids, a significant overall association was found. There was a suggestion of an inverse association for flavanones and isoflavones among women with body mass index <25 kg m(-2), and, for flavanones, among parous or non-users of hormone-replacement therapy women. CONCLUSION: High consumption of selected proanthocyanidins may reduce endometrial cancer risk.

The relative effects of prenatal and postnatal low-level mercury exposure and fish intake on child neurodevelopment are still controversial. Limited evidence is available from Mediterranean populations. In this prospective study, we measured the Verbal and Performance IQ in Italian children at school-age who were resident in an area declared as a National contaminated site because of mercury pollution, taking into account the possible beneficial effect of fish consumption and potential confounders. A mother-child cohort made up of 242 children was established at birth in Northeastern Italy in 2001. Their mothers were interviewed approximately 2 months after delivery to determine type, quantity, and origin of fish consumed during pregnancy and about a number of mother, child and family characteristics. Total mercury (THg) and methyl mercury (MeHg) were assessed in maternal hair and breast milk and in the child's hair. When children reached 7-9 years of age, 154 (63.6%) parents gave consent to participate in a follow-up evaluation. On that occasion, a child's hair sample was collected to determine the current concentration of THg, mothers were asked to complete a self-administered questionnaire, and children underwent neuropsychological testing. Verbal IQ, performance IQ and full scale IQ were measured by the Wechsler Intelligence Scale for Children (WISC III) administered by psychologists at school or local health centers. Demographic, socioeconomic and lifestyle information, medical information of the child's family and the child's dietary habits were collected using a questionnaire filled in by mothers. Multivariable linear regression models were used to evaluate the association between prenatal THg exposure through fish consumption of mothers in pregnancy and children's IQ after adjustment for possible confounders such as fish consumption of mothers in pregnancy, child's fish consumption at follow-up, child's birthweight, maternal cigarette smoking during pregnancy, house size and property place of residence during pregnancy and gender. THg in the child's hair at 7 years of age was fairly correlated with THg in maternal hair at delivery (rs=0.35; p<0.0001) and was strongly correlated with child's seafood consumption (rs=0.50, p<0.0001). No differences in maternal THg levels were found when comparing children with low or extremely low or high or extremely high scores vs others, considering separately full scale, verbal, and performance IQs. Children born from mothers with hair THg levels greater than or equal to 2000ng/g had full scale, verbal and performance IQs which were 4-5 points lower than children born from women with lower THg levels, but these differences were not statistically significant. Fresh fish intake of mothers in pregnancy was slightly positively associated with full scale and performance but not so with verbal IQs. Canned fish showed to be negatively associated with all the outcome variables. Unexpectedly, children born to mothers from one town showed IQ scores significantly lower than the other children; however, none of the many variables considered in these analyses could explain this result. The relatively low Hg levels found in the biological samples did not provide evidence of high and extensive Hg exposure in this population. Although THg levels in maternal and child's biological samples are correlated with fish consumption, the effects of THg and fish on neurological outcomes go in opposite directions. These results do not allow to develop recommendations regarding fish consumption in pregnancy but suggest that keeping THg hair levels<2000ng/g might be desirable.

BACKGROUND: Dietary habits have been related to the risk of nasopharyngeal carcinoma (NPC), but information on a wide range of macro- and micronutrients is still lacking, particularly for low-incidence countries. METHODS: We conducted a hospital-based case-control study in Italy on 198, histologically confirmed, NPC cases of Caucasian ethnicity of 18-76 years of age. Controls were 594 Caucasian cancer-free patients admitted to general hospitals for acute conditions. Nutrients intake was assessed through a validated food-frequency questionnaire. Adjusted odds ratios (ORs) and the corresponding confidence intervals (CIs) were estimated through logistic regression. RESULTS: Dietary intake of carotenoids were inversely related to NPC risk, notably carotene (OR for highest vs lowest quartile=0.46; 95% CI: 0.26-0.79), α-carotene (OR=0.57; 95% CI: 0.33-0.97), and ß-carotene (OR=0.42; 95% CI: 0.24-0.75). Increased NPC risk was observed for elevate cholesterol intake (OR=1.85; 95% CI: 1.12-3.05). CONCLUSION: Study findings suggest a protective effect of carotenoids against NPC in a low-risk population, adding further support to a possible beneficial role of a diet rich in fruits and vegetables in cancers of the head and neck.

BACKGROUND/OBJECTIVE: The European Food Safety Authority (EFSA) recently published dietary guidelines for the intakes of carbohydrates, fiber, fats and water. We evaluated their role on the risk of a specific disease, known to be related to diet. SUBJECTS/METHODS: We used data from an Italian case-control study including 1953 colorectal cancer (CRC) cases and 4154 controls. We developed a so-called EFSA index summing up 1 point for adherence to each EFSA guideline. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) of CRC and its subsites were derived from unconditional multiple logistic regression models, for both the index and its components. RESULTS: When each EFSA index component was analyzed separately, we found significant increased risks of CRC for non adherence to the guidelines on linoleic (OR=1.20, 95% CI, 1.07-1.36) and alpha-linolenic fatty acids (OR=1.19, 95% CI, 1.06-1.34). When all the guidelines were included in the same model, no significant association emerged. Compared with minimal adherence, the ORs of CRC for subsequent EFSA index scores were 1.03 (95% CI, 0.72-1.47), 1.05 (95% CI, 0.75-1.48), 1.04 (95% CI, 0.81-1.60), 0.99 (95% CI, 0.69-1.43), and 1.04 (95% CI, 0.67-1.61). No significant association emerged for colon and rectal cancer separately, and for males and females. CONCLUSIONS: Overall adherence to the EFSA dietary guidelines is not associated to colorectal, colon and rectal cancer risk in our population. Adherence to guidelines on linoleic and alpha-linolenic fatty acids may have a modest beneficial role on CRC risk.

OBJECTIVES: The increasing incidence of multiple sclerosis (MS) worldwide, especially in women, points to the crucial role of environmental and lifestyle risk factors in determining the disease occurrence. An international multicentre case-control study of Environmental Risk Factors In Multiple Sclerosis (EnvIMS) has been launched in Norway, Sweden, Italy, Serbia and Canada, aimed to examine MS environmental risk factors in a large study population and disclose reciprocal interactions. To ensure equivalent methodology in detecting age-related past exposures in individuals with and without MS across the study sites, a new questionnaire (EnvIMS-Q) is presented. MATERIALS AND METHODS: EnvIMS-Q builds on previously developed guidelines for epidemiological studies in MS and is a 6-page self-administered postal questionnaire. Participants are de-identified through the use of a numerical code. Its content is identical for cases and controls including 'core' and population-specific questions as proxies for vitamin D exposure (sun exposure, dietary habits and supplementation), childhood infections (including infectious mononucleosis) and cigarette smoking. Information on possible confounders or effect modifiers is also obtained. EnvIMS-Q was initially drafted in English and subsequently translated into Italian, Serbian, Norwegian, Swedish and French-Canadian. EnvIMS-Q has been tested for acceptability, feasibility and reliability. RESULTS AND CONCLUSIONS: EnvIMS-Q has shown cross-cultural feasibility, acceptability and reliability in both patients with MS and healthy subjects from all sites. EnvIMS-Q is an efficient tool to ensure proper assessment of age-specific exposure to environmental factors in large multinational population-based case-control studies of MS risk factors.

BACKGROUND: The association between dietary patterns and head and neck cancer has rarely been addressed. PATIENTS AND METHODS: We used individual-level pooled data from five case-control studies (2452 cases and 5013 controls) participating in the International Head and Neck Cancer Epidemiology consortium. A posteriori dietary patterns were identified through a principal component factor analysis carried out on 24 nutrients derived from study-specific food-frequency questionnaires. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using unconditional logistic regression models on quintiles of factor scores. RESULTS: We identified three major dietary patterns named 'animal products and cereals', 'antioxidant vitamins and fiber', and 'fats'. The 'antioxidant vitamins and fiber' pattern was inversely related to oral and pharyngeal cancer (OR=0.57, 95% CI 0.43-0.76 for the highest versus the lowest score quintile). The 'animal products and cereals' pattern was positively associated with laryngeal cancer (OR=1.54, 95% CI 1.12-2.11), whereas the 'fats' pattern was inversely associated with oral and pharyngeal cancer (OR=0.78, 95% CI 0.63-0.97) and positively associated with laryngeal cancer (OR=1.69, 95% CI 1.22-2.34). CONCLUSIONS: These findings suggest that diets rich in animal products, cereals, and fats are positively related to laryngeal cancer, and those rich in fruit and vegetables inversely related to oral and pharyngeal cancer.

BACKGROUND: Hepatitis B virus (HBV) and hepatitis C virus (HCV) are the major risk factors for hepatocellular carcinoma (HCC). The association of diabetes mellitus with HCC suggests that dietary glycemic load (GL) may influence HCC risk. We have examined the association between dietary GL and HCC. PATIENTS AND METHODS: We conducted a hospital-based case-control study in Italy in 1999-2002, including 185 HCC cases and 412 controls who answered a validated food frequency questionnaire and provided blood samples. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were computed using unconditional multiple logistic regression. RESULTS: We observed a positive association between GL and HCC overall, with an OR of 3.02 (95% CI 1.49-6.12) for the highest quintile of GL compared with the lowest and a significant trend. The OR among HCC cases with evidence of chronic infection with HBV and/or HCV was 3.25 (95% CI 1.46-7.22), while the OR among those with no evidence of infection was 2.45 (95% CI 0.69-8.64), with no significant trend. The association was not explained by the presence of cirrhosis or diabetes. CONCLUSIONS: High dietary GL is associated with increased risk for HCC. The positive association was most pronounced among HCC cases with HBV and/or HCV markers.

BACKGROUND: There is some evidence that dietary habits may influence the risk of endometrial cancer independently of body mass, although the role of diet on endometrial carcinogenesis is unclear. PATIENTS AND METHODS: We carried out a multicenter case-control study from 1992 to 2006 in Italy on 454 women with incident, histologically confirmed endometrial cancer (age range 18-79 years) and 908 controls (age range 19-79 years) admitted to hospitals for acute, non-neoplastic diseases. A validated food-frequency questionnaire was used to estimate macronutrients, fatty acids and cholesterol intake. Logistic regression models, conditioned on age and study centre, and adjusted for major known risk factor of endometrial cancer and residual of energy intake were used to estimate odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Significant direct associations were observed with intake of energy (OR = 1.7 for the highest versus the lowest quintile, 95% CI = 1.1-2.5), and cholesterol (OR = 2.1, 95% CI = 1.4-3.2), while a direct borderline association emerged with saturated fatty acids (OR = 1.3, 95% CI = 0.9-2.0). There was no association with proteins, sugars, starch, total fat and other selected fatty acids. CONCLUSION: Energy and cholesterol intake were associated with endometrial cancer.

BACKGROUND: Flavonoids may play an important role in explaining the protective effect of vegetables and fruit against cancer. PATIENTS AND METHODS: To investigate the relation between flavonoids and laryngeal cancer risk, we have applied data on the composition of foods and beverages in terms of six principal classes of flavonoids to a case-control study of laryngeal cancer conducted from 1992 to 2000 in Italy. Cases were 460 subjects with incident, histologically confirmed laryngeal cancer; controls were 1088 patients admitted for acute, non-neoplastic diseases. Odds ratios (OR) were estimated through multiple logistic regression models, including terms for sociodemographic and lifestyle factors, tobacco smoking, alcohol consumption and energy intake. RESULTS: Significant inverse relations were found for the highest versus the lowest quintile of intake for flavan-3-ols (OR = 0.64), flavanones (OR = 0.60), flavonols (OR = 0.32) and total flavonoids (OR = 0.60), although the overall trends in risk were significant only for flavanones and flavonols. No consistent associations were observed for isoflavones, anthocyanidins and flavones. The estimates did not differ substantially across strata of alcohol drinking, tobacco smoking, body mass index and education, and tended to persist even after controlling for vegetable and fruit intake. CONCLUSION: This study provides support for a beneficial effect of selected flavonoids on laryngeal cancer risk.

OBJECTIVE: This paper describes the ad hoc methodological concepts and procedures developed to improve the comparability of Nutrient databases (NDBs) across the 10 European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). This was required because there is currently no European reference NDB available. DESIGN: A large network involving national compilers, nutritionists and experts on food chemistry and computer science was set up for the 'EPIC Nutrient DataBase' (ENDB) project. A total of 550-1500 foods derived from about 37,000 standardized EPIC 24-h dietary recalls (24-HDRS) were matched as closely as possible to foods available in the 10 national NDBs. The resulting national data sets (NDS) were then successively documented, standardized and evaluated according to common guidelines and using a DataBase Management System specifically designed for this project. The nutrient values of foods unavailable or not readily available in NDSs were approximated by recipe calculation, weighted averaging or adjustment for weight changes and vitamin/mineral losses, using common algorithms. RESULTS: The final ENDB contains about 550-1500 foods depending on the country and 26 common components. Each component value was documented and standardized for unit, mode of expression, definition and chemical method of analysis, as far as possible. Furthermore, the overall completeness of NDSs was improved (>or=99%), particularly for beta-carotene and vitamin E. CONCLUSION: The ENDB constitutes a first real attempt to improve the comparability of NDBs across European countries. This methodological work will provide a useful tool for nutritional research as well as end-user recommendations to improve NDBs in the future.

BACKGROUND: Dietary habits have been suggested as a factor related to the increase of non-Hodgkin lymphoma (NHL) incidence in western populations, but the role of individual nutrients is still unclear. PATIENTS AND METHODS: A hospital-based case-control study was conducted in Italy, 1999-2002. CASES: 190 incident, histologically-confirmed NHL cases aged 18-84 years. CONTROLS: 484 subjects admitted to hospital for acute, non-neoplastic diseases unrelated to diet. Dietary habits were assessed by a validated food-frequency questionnaire; nutrient intakes were computed using the Italian food composition database. Odds ratios (ORs) and corresponding 95% confidence intervals (CI) for tertiles of intake of nutrient were computed using the energy-adjusted residual models. RESULTS: Inverse association emerged for polyunsaturated fatty acids (OR=0.6; 95% CI: 0.4-0.9), linoleic acid (OR=0.6; 95% CI: 0.4-0.9), and vitamin D (OR=0.6; 95% CI: 0.4-0.9). The protective effect for linoleic acid (OR=0.3; 95% CI: 0.2-0.7) and vitamin D (OR=0.4; 95% CI: 0.2-0.9) was stronger in women; no differences emerged according to age. Linoleic acid was inversely related to follicular and diffuse large B-cell lymphoma; the protective effect of vitamin D emerged most clearly for follicular subtypes. CONCLUSIONS: Our study suggests that a diet rich in polyunsaturated fatty acids and vitamin D is associated with a reduced risk of NHL.

BACKGROUND: Folate and vitamin B6 intake has been associated with reduced risk of coronary heart disease, but studies are not consistent. OBJECTIVE: The relation between folate and vitamin B6 intake and the risk of acute myocardial infarction (AMI) was assessed in a Mediterranean population. DESIGN: A hospital-based case-control study was conducted in Milan, Italy, between 1995 and 1999. Information was collected by interviewer-administered questionnaires. Adjusted odds ratios (ORs) and 95% confidence intervals (CI) were obtained by multiple logistic regression models. SUBJECTS: Cases were 507 patients with a first episode of nonfatal AMI, and controls were 478 patients admitted to hospital for acute conditions. RESULTS: Compared to patients in the lowest tertile of intake, the ORs for those in the highest tertile were 0.56 (95% CI 0.35-0.88) for folate and 0.34 (95% CI 0.19-0.60) for vitamin B6. The OR was consistently below unity in strata of sex, age, alcohol, methionine, tobacco smoking, coffee, hypertension and family history of AMI; the inverse association was apparently stronger for vitamin B6 in regular alcohol drinkers than in no or occasional drinkers. Compared to subjects with a low intake of both micronutrients, the OR was 0.29 for those with a high intake of both. Compared to subjects reporting no or occasional alcohol drinking and low methionine and folate intake, the OR was 0.28 in regular drinkers with high methionine and high folate intake. The corresponding value for vitamin B6 was 0.25. CONCLUSIONS: A high intake of folates, vitamin B6 and their combination is inversely associated with AMI risk.

OBJECTIVE: The reproducibility and validity of coffee, decaffeinated coffee and tea intake has not been adequately studied, particularly in Italy, where coffee drinking is peculiar in terms of type and amount of coffee consumed. DESIGN: We compared coffee and tea consumption, measured by two interviewer-administered food frequency questionnaires (FFQ), with average intake derived from two 7-day dietary (DD) records (the reference method) on 395 volunteers. The Pearson correlation coefficients (r) were used to assess both reproducibility and validity of information on coffee intake. RESULTS: A satisfactory level of reproducibility and validity of the pattern consumption was observed for coffee, decaffeinated coffee and tea. The reproducibility for both sex combined showed r of 0.74-0.78 for coffee, 0.57-0.65 for decaffeinated coffee and 0.61-0.67 for tea. The validity was about 0.70 for coffee, around 0.58 for decaffeinated coffee and 0.56-0.60 for tea intake. CONCLUSIONS: The FFQ is a satisfactorily reliable and valid instrument for collecting information on coffee, decaffeinated coffee and tea intake.

BACKGROUND: Dietary carbohydrates vary in their ability to raise blood glucose and insulin levels, which, in turn, influence levels of sex hormones and insulin-like growth factors. We analyzed the effect of type and amount of carbohydrates on ovarian cancer risk, using the glycemic index (GI) and the glycemic load (GL) measurement in a large case-control study conducted in Italy. MATERIALS AND METHODS: Cases included 1031 women with incident, histologically confirmed epithelial ovarian cancer, from four Italian regions. Controls included 2411 women admitted to the same hospital networks for acute, non-neoplastic conditions. Average daily GI and GL were calculated from a validated food frequency questionnaire. Odds ratios (OR) and the corresponding 95% confidence intervals (CI) were computed using multiple logistic regression. RESULTS: Ovarian cancer was directly associated with dietary GI (OR for highest versus lowest quartile = 1.7, 95% CI 1.3-2.1) and GL (OR = 1.7, 95% CI 1.3-2.1). The associations were observed in pre- and postmenopausal women, and they remained consistent across strata of major covariates identified. CONCLUSIONS: This study supports the hypothesis of a direct association between GI and GL and ovarian cancer risk and, consequently, of a possible role of hyperinsulinemia/insulin resistance in ovarian cancer development.
