Abstract
BackgroundThe main goal for the management of rheumatoid arthritis (RA) is to control symptoms to reach clinical remission or low disease activity as the best possible alternative [1]. Although the number of available therapeutic options, a substantial proportion of patients remain symptomatic. Recent EULAR recommendations [2] shift focus to lifestyle interventions whose concurrent approach could help in controlling potential inflammatory triggers. In this context, olives and olive oil have beneficial properties on health mainly attributed to their high monounsaturated fatty acid content, and to the presence of phenolic compounds. To our knowledge, very few studies addressed the anti-inflammatory effects related to olives and olive oil consumption on RA disease activity.ObjectivesTo study the attitude of consumption of olives and olive oil in RA patients from northern Italy, and to assess the effect on disease activity.MethodsIn this observational cross-sectional study, all consecutive adult RA with disease duration ≥ 3 months were enrolled. Disease Activity Score on 28 joints (DAS28-CRP), Simple Disease Activity Index (SDAI) were recorded. Dietary habits in the previous six months were collected with a with a 110-item food frequency questionnaire. In this analysis, we focus on olive oil consumption with original response categories ranging from “never” to “more than 2 times per day” (in spoon units). We created a food group composed by olive oil, black and green olives (frequencies/day). Olive oil consumption was entered as the independent variable into multiple regression models. When disease activity was entered in continuous in the regression models, we estimated the effect on a 1-point increment/decrease in RA disease activity. When disease activity was modeled as a dichotomous variable, we estimated the odds ratios (ORs) of disease activity and the corresponding 95% confidence intervals (CIs) within unconditional multiple logistic regression models. We included in each model the potential confounding variables: age, sex, education, body mass index (BMI), cigarette smoking status, alcohol drinking intensity, disease duration, rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA), and therapies.Results365 RA patients (median age: 58.46 years, 78.63% females) were included. Most of the patients (60.55%) finished the high school and/or the university. The median BMI was 23.63 (IQR: 21.00-26.78) Kg/m2; never smokers or drinkers were 51.64% and 29.04%, respectively. The median disease duration was 12.81 (IQR: 8.08-20.72) years, with RF positivity being 53.70% and ACPA positivity 50.96%. Disease activity measures DAS28-CRP and SDAI showed medians of 2.21 (IQR: 1.613.02) and 6.30 (IQR: 3.01-11.81), with high disease activity present in 3.84% and 5.75% of the sample, respectively. Major comorbidities included arterial hypertension (33.42%), gastro-esophageal reflux (19.18%), and gastritis (8.77%). After adjustment for the mentioned confounding factors, the ORs (and the corresponding 95% confidence interval) of RA disease activity was equal to 0.78 (95% CI: 0.76-1.31) for DAS28-CRP and to 0.76 (95% CI: 0.75-1.34) for SDAI, suggesting significant protection of about ~20% for both outcomes. Similarly, robust regression models for estimating the increment in the mean outcome disease activity scores, DAS28-CRP and SDAI in continuous, provided beta coefficients equal to -0.17 (Standard Error, SE: 0.06) with a p-value equal to 0.06 for DAS28-CRP and a beta coefficient of -1.13 (SE: 0.37) with a p-value equal to 0.04.ConclusionIncreasing frequency of consumption of a food group composed by olive oil, black and green olives is significantly associated to a lower risk of disease activity, as measured by both DAS28-CRP and SDAI, after adjustment for socio-demographic factors, therapy, disease duration and severity. Robust regression models allowed to quantify the mean reduction of DAS28-CRP in 0.17 points and that of SDAI in 1.13 points.References[1]Ann Rheum Dis 2020;79:685–699.[2]Ann Rheum Dis 2021;80:1278-1285AcknowledgementsThe authors thank the RANDIE study groupDisclosure of InterestsFrancesca Ingegnoli: None declared, Roberta De Vito: None declared, Roberto Caporali Speakers bureau: Abbvie, Amgen, BMS, Celltrion, Galapagos, Lilly, Pfizer, Fresenius-Kabi, MSD, UCB, Roche,Janssen, Novartis, Sandoz, Consultant of: Abbvie, Amgen, BMS, Celltrion, Galapagos, Lilly, Pfizer, MSD, UCB, Janssen, Novartis, Sandoz, Maria Parpinel: None declared, Giuseppe Grosso: None declared, Monica Ferraroni: None declared, Valeria Edefonti: None declared

Abstract
Smoking trends and patterns in Italy were evaluated using data from the 1986-87 Italian National Health Survey, based on a sample of 30,096 males and 32,176 females aged 15 or over, randomly selected within strata of geographical areas and sizes of the place of residence and of the household in order to be representative of the whole Italian population: 40.8 % of Italian males and 17.3 % of females described themselves as current smokers (overall estimated prevalence, 28.6 %). In comparison with previous survey-based data, self-reported smoking prevalence in males has been steadily decreasing over the last three decades, whereas rates in females have been increasing up to the early 1980s, and have shown a levelling off only in more recent years. The apparent declines in self-reported smoking, however, were not reflected in official sales figures. In fact, in the mid 1980s, there were simultaneously the lowest overall prevalence of the last three decades and the highest sales figures ever reported. The inter-sex differences in smoking prevalence were smaller at younger ages. Education, but not occupation as a measure of social class, was inversely related to smoking prevalence in males. Furthermore, rates for males were lower in the northern (and richer) part of the country. The pattern was totally different in females, since smoking prevalence was higher in more educated women, of higher social class, living in North Italy. This suggests that, in the absence of adequate measures, smoking prevalence is likely to rise among Italian women in the near future. Continued monitoring of smoking patterns gives important information with which to identify the most likely future patterns in smoking and smoking-related diseases, besides providing data for targeting intervention programs.

Abstract
Smoking prevalence and patterns in Italy were analyzed using data from the 1990-1991 Italian National Health Survey, based on a sample of 27, 135 males and 28,854 females aged 15 years or over, randomly selected within strata of geographic area and size of the place of residence and of the household, in order to be representative of the general Italian population. Overall, 26.9% of the Italians aged 15 years or over described themselves as current smokers (37.2% males, 17.4% females), and 14.0% as ex-smokers (22.2% males, 6.4% females). The difference in smoking prevalence between males and females was 65% below age 45, but increased substantially with increasing age up to 5-fold above age 65. Moderate smokers (< 15 cigarettes per day) were 12.6% of males and 10.4% of females, intermediate smokers (15 to 24 cigarettes per day) 17.7% of males and 5.5% of females, and heavy smokers (> 25 cigarettes per day) 6.3% of males and 1.5% of females. Pipe or cigar smokers were 0.6% of males. The averange number of cigarettes per smoker per day was 16.6 (17.9 for males, 14.0 for females). The overall smoking prevalence of 26.9% was the lowest registered since 1949, thus confirming the long-term steady decline of smoking, particularly among males. Smoking prevalence, however, has remained constant over the last 15 years among females, after substantial rises in previous calendar years. These falls in overall self-reported smoking prevalence were reflected in declines of legal sale figures (-15% between 1986 and 1991), although it is difficult to quantify the impact of smuggling on total tobacco consumption. Thus, at least part of the falls in self-reported tobacco consumption is attributable to increased underreporting. In males, but not in females, smoking was less frequent in northern (and wealthier) areas of the country, and in more educated individuals. The opposite pattern was observed in females, indicating that even more educated Italian women have not yet recognized the accumulated evidence on the health consequences of smoking. These patterns in smoking are reflected by recent trends in lung cancer, which show some decline in males but persistent upward trends in females, although still on much lower absolute values.

Abstract
The pattern of cervical screening utilization in Italy was analyzed using data from the 1986-1987 National Health Survey on the basis of a sample of 27,455 women aged 20 to 79 randomly selected within strata of municipality of residence and age in order to be representative of the whole Italian population. Overall, about 17% of women aged 20 to 79 were screened per year, for a total of 3.5 to 4 million cervical smears per year. The highest frequency was reported in younger middle age, about one in four women being screened per year in the age groups 30 to 49, and there was a substantial decline above age 50. Cervical smear rates were higher in Northern areas (22 %), where mortality from cervical cancer is lower, than in the Centre (16%) and South (11 %) of the country. Further, there was a strong positive social class gradient in the utilization of cervical screening, in relation to both education and occupation. In spite of the absence of any organised mass screening program, cervical screening is a relatively common procedure among Italian women. However, this study provides further quantitative evidence of a markedly irrational utilization of non-organized cervical screening, which tends to end up selectively used by the groups in which cervical cancer is less common.

Abstract
The binding properties toward the human telomeric G-quadruplex of the two natural alkaloids coptisine and chelerythrine were studied using spectroscopic techniques, molecular modeling, and X-ray diffraction analysis. The results were compared with reported data for the parent compounds berberine and sanguinarine. Spectroscopic studies showed modest, but different rearrangements of the DNA-ligand complexes, which can be explained considering particular stereochemical features for these alkaloids, in spite of the similarity of their skeletons. In fact, the presence of a dioxolo moiety rather than the two methoxy functions improves the efficiency of coptisine and sanguinarine in comparison to berberine and chelerythrine, and the overall stability trend is sanguinarine > chelerythrine ≈ coptisine > berberine. Accordingly, the X-ray diffraction analysis confirmed the involvement of the benzodioxolo groups in the coptisine/DNA binding by means of π···π, O···π, and CH···O interactions. Similar information is provided by modeling studies, which, additionally, evidenced reasons for the quadruplex vs double-helix selectivity shown by these alkaloids. Thus, the analyses shed light on the key role of the benzodioxolo moieties in strengthening the interaction with the G4-folded human telomeric sequence and indicated the superior G4 stabilizing properties of the benzophenanthridine scaffold with respect to the protoberberine one and conversely the better G4 vs dsDNA selectivity profile of coptisine over the other alkaloids.

Abstract
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.

Abstract
BACKGROUND To our knowledge, no study assessed the association between dietary patterns and nasopharyngeal carcinoma (NPC) in low-incidence areas. METHODS We examined this association in a hospital-based case-control study carried out in Italy between 1992 and 2008, including 198 incident NPC cases and 594 controls. A posteriori dietary patterns were identified through principal component factor analysis performed on 28 nutrients and minerals derived from a 78-item food-frequency questionnaire. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional multiple logistic regression models on tertiles of factor scores. RESULTS We identified five dietary patterns named Animal products, Starch-rich, Vitamins and fibre, Animal unsaturated fatty acids (AUFAs), and Vegetable unsaturated fatty acids (VUFAs). The Animal product (OR=2.62, 95% CI=1.67-4.13, for the highest vs lowest score tertile), Starch-rich (OR=2.05, 95% CI=1.27-3.33), and VUFA (OR=1.90, 95% CI=1.22-2.96) patterns were positively associated with NPC. The AUFA pattern showed a positive association of borderline significance, whereas the Vitamins and fibre pattern was nonsignificantly but inversely associated with NPC. CONCLUSIONS These findings suggest that diets rich in animal products, starch, and fats are positively related to NPC risk in this low-incidence country.

Abstract
Background: The Mediterranean diet has been shown to have a beneficial role on various neoplasms, but data are scanty on pancreatic cancer. Methods: We analysed data from two case–control studies conducted in Italy between 1983 and 2008, including 362 and 326 pancreatic cancer cases and 1552 and 652 hospital-controls, respectively. A Mediterranean Diet Score (MDS) summarising major characteristics of the Mediterranean diet was used in the two studies separately and overall. Two further scores of adherence to the Mediterranean diet were applied in the second study only, the Mediterranean Dietary Pattern Adherence Index (MDP) and the Mediterranean Adequacy Index (MAI). Results: Odds ratios (ORs) for increasing levels of the scores (i.e., increasing adherence) were estimated using multiple logistic regression models. Odds ratio for a MDS score ⩾6 compared with <3 was 0.57 (95% confidence interval (CI) 0.34–0.95) in the first study, 0.51 (95% CI 0.29–0.92) in the second study, and 0.48 (95% CI 0.35–0.67) overall. A trend of decreasing risk was observed also for the MDP and MAI the ORs for the highest vs the lowest quintile being 0.44 (95% CI 0.27–0.73) for MDP and 0.68 (95% CI 0.42–1.11) for the MAI. The results were consistent across strata of age, sex, education, body mass index, alcohol drinking, tobacco smoking, and diabetes. Conclusion: Our study provides evidence that a priori-defined scores measuring adherence to the Mediterranean diet are favourably associated with pancreatic cancer risk.

Abstract
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.

Abstract
BACKGROUND The risk of many cancers is higher in subjects with a family history (FH) of cancer at a concordant site. However, few studies investigated FH of cancer at discordant sites. PATIENTS AND METHODS This study is based on a network of Italian and Swiss case-control studies on 13 cancer sites conducted between 1991 and 2009, and including more than 12 000 cases and 11 000 controls. We collected information on history of any cancer in first degree relatives, and age at diagnosis. Odds ratios (ORs) for FH were calculated by multiple logistic regression models, adjusted for major confounding factors. RESULTS All sites showed an excess risk in relation to FH of cancer at the same site. Increased risks were also found for oral and pharyngeal cancer and FH of laryngeal cancer (OR = 3.3), esophageal cancer and FH of oral and pharyngeal cancer (OR = 4.1), breast cancer and FH of colorectal cancer (OR = 1.5) and of hemolymphopoietic cancers (OR = 1.7), ovarian cancer and FH of breast cancer (OR = 2.3), and prostate cancer and FH of bladder cancer (OR = 3.4). For most cancer sites, the association with FH was stronger when the proband was affected at age <60 years. CONCLUSIONS Our results point to several potential cancer syndromes that appear among close relatives and may indicate the presence of genetic factors influencing multiple cancer sites.

Abstract
BACKGROUND The number of original articles investigating the efficacy of cosmetic products in cellulite reduction increased rapidly in the last decade; however, to our knowledge, no systematic review and meta-analysis has been performed so far. OBJECTIVE We conducted a systematic review of in vivo studies on humans adopting the PRISMA guidelines. Moreover, we used a meta-analytic approach to estimate the overall effect of cosmetic creams in cellulite treatment from controlled trials with more than 10 patients per arm, using thigh circumference reduction as the outcome measure. METHODS Medline and Embase were searched up to August 2012 to identify eligible studies. RESULTS Twenty-one original studies were included in the present systematic review. All studies were clinical trials, most of them recruited women only and 67% had an intra-patient study design. About half of the active cosmetic creams tested only contained one active ingredient among xanthenes, herbals or retinoids. The other studies tested cosmetic creams with more complex formulations and most of them included xanthenes. A total of seven controlled trials satisfied the inclusion criteria for the meta-analysis. The pooled mean difference of thigh circumference reduction between the treated and the controlled group was -0.46 cm (95% confidence intervals, CI: -0.85, -0.08), with significant heterogeneity between studies (P < 0.001). CONCLUSION This article provides a systematic evaluation of the scientific evidence of the efficacy of cosmetic products in cellulite reduction and supports a moderate efficacy in thigh circumference reduction.

Abstract
BACKGROUND Declines in gastric cancer (GC) incidence and mortality have been related to improvements in diet. It is therefore important to consider dietary patterns. DESIGN We conducted a systematic review and meta-analysis of the literature through Medline and Embase databases. RESULTS We identified 16 papers, of these 9 derived dietary patterns through an a posteriori method, 5 through a priori scores, and 2 used both approaches. Eight studies that used the a posteriori approach were considered for the meta-analysis. A favorable role on GC emerged for the 'Prudent/healthy', with an odds ratio (OR) of 0.75 [95% confidence interval (CI): 0.63-0.90], for the highest versus the lowest category. Similar results emerged for separate anatomical subtypes. An unfavorable role on GC emerged for the 'Western/unhealthy' dietary pattern, with an OR of 1.51 (95% CI: 1.21-1.89). This association was weaker for the distal/NOS (not otherwise specified) category (OR = 1.36) compared with the cardia GC (OR = 2.05). Among the a priori scores, the ORs ranged from 0.2 to 0.7 for the favorable and from 1.8 to 6.9 for the unfavorable ones. CONCLUSION There is a ~2-fold difference in GC risk between a 'Prudent/healthy' diet-rich in fruits and vegetables, and a 'Western/unhealthy' diet-rich in starchy foods, meat and fats.

Abstract
BACKGROUND The relationship between diet and cancers of the upper aerodigestive tract (UADT) has been investigated through dietary patterns. DESIGN Published studies on the relationship between a priori and a posteriori dietary patterns and UADT cancers were selected through a Medline search. RESULTS Twenty-four case-control studies were identified. Most of them identified a posteriori dietary patterns, mainly using principal component factor analysis, and a few used a priori dietary patterns, based on the available evidence on known effects of dietary habits on UADT cancers. In one study, no association was found between the identified patterns and UADT cancers. All the remaining 23 papers reported at least one favorable or unfavorable dietary pattern related to UADT cancers. The most consistent findings are the beneficial role of a dietary pattern based on fruit and vegetables or nutrients mostly contained in such foods, and the unfavorable role of an alcohol drinker pattern. A possible unfavorable role of patterns based on meats and animal products emerged as well. CONCLUSION The consistency of results among populations indicates that diets rich in fruit and vegetables, and poor in alcohol and animal products are favorable for UADT cancers.

Abstract
BACKGROUND The role of dietary habits on esophageal cancer risk has been rarely considered in terms of dietary patterns. PATIENTS AND METHODS We analyzed data from an Italian case-control study, including 304 cases with squamous cell carcinoma of the esophagus and 743 hospital controls. Dietary habits were evaluated using a food frequency questionnaire. A posteriori dietary patterns were identified through principal component factor analysis performed on 28 selected nutrients. Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained from multiple logistic regression models applied on quartiles of factor scores, adjusting for potential confounding variables. RESULTS We identified five major dietary patterns, named 'animal products and related components', 'vitamins and fiber', 'starch-rich', 'other polyunsaturated fatty acids and vitamin D', and 'other fats'. The 'animal products and related components' pattern was positively related to esophageal cancer (OR = 1.64, 95% CI:1.06-2.55, for the highest versus the lowest quartile of factor scores category). The 'vitamins and fiber' (OR = 0.50, 95% CI: 0.32-0.78) and the 'other polyunsaturated fatty acids and vitamin D' (OR = 0.48, 95% CI: 0.31-0.74) were inversely related to esophageal cancer. No significant association was observed for the other patterns. CONCLUSION Our findings suggest that a diet rich in foods from animal origin and poor in foods containing vitamins and fiber increase esophageal cancer risk.

Abstract
BACKGROUND Limited information is available on the relationship between dietary patterns and breast and ovarian cancers. PATIENTS AND METHODS Cases were 2569 breast cancers and 1031 ovarian cancers hospitalized in four Italian areas from 1991 to 1999. Controls were 3413 women in hospital for acute non-neoplastic diseases. Dietary habits were investigated through a validated food-frequency questionnaire. Dietary patterns were obtained from a K-means clustering on factor scores from factor analysis. Odds ratios (ORs) for both cancers were estimated using unconditional multiple logistic regression models on clusters of patients. Floating absolute risk method was used for reporting 95% floating confidence intervals (FCIs). RESULTS We identified five groups of subjects. The G3 cluster, including subjects with the lowest intakes of any food group, was used as reference. The G5 cluster, including subjects mainly consuming bread and pasta, was unfavorable for both cancers (OR=1.23, 95% FCI=1.08-1.38 for breast cancer, OR=1.21, 95% FCI=1.03-1.42 for ovarian cancer). The G1 group, including subjects mainly consuming fruits and vegetables, was protective against ovarian cancer (OR=0.81, 95% FCI=0.67-0.98). CONCLUSIONS A diet mainly based on bread and pasta is unfavorable for breast and ovarian cancers; a diet rich in fruits and vegetables may be associated with a reduced risk of ovarian cancer.

Abstract
Salicylate 1,2-dioxygenase, a new ring-fission dioxygenase from the naphthalenesulfonate-degrading strain Pseudaminobacter salicylatoxidans which oxidizes salicylate to 2-oxohepta-3,5-dienedioic acid by a novel ring-fission mechanism, has been crystallized. Diffraction-quality crystals of salicylate 1,2-dioxygenase were obtained using the sitting-drop vapour-diffusion method at 277 K from a solution containing 10%(w/v) ethanol, 6%(w/v) PEG 400, 0.1 M sodium acetate pH 4.6. Crystals belong to the primitive tetragonal space group P4(3)2(1)2 or P4(1)2(1)2, with unit-cell parameters a = 133.3, c = 191.51 A. A complete data set at 100 K extending to a maximum resolution of 2.9 A was collected at a wavelength of 0.8423 A. Molecular replacement using the coordinates of known extradiol dioxygenases structures as a model has so far failed to provide a solution for salicylate 1,2-dioxygenase. Attempts are currently being made to solve the structure of the enzyme by MAD experiments using the anomalous signal of the catalytic Fe(II) ions. The salicylate 1,2-dioxygenase structural model will assist in the elucidation of the catalytic mechanism of this ring-fission dioxygenase from P. salicylatoxidans, which differs markedly from the known gentisate 1,2-dioxygenases or 1-hydroxy-2-naphthoate dioxygenases because of its unique ability to oxidatively cleave salicylate, gentisate and 1-hydroxy-2-naphthoate with high catalytic efficiency.

Abstract
Resveratrol is a non-flavonoid polyphenol that has attracted attention as a potential anticancer agent in vitro and in vivo, but scanty epidemiological data are available. We have therefore analysed the relation between dietary intake of resveratrol and breast cancer risk using data from a case-control study conducted between 1993 and 2003 in the Swiss Canton of Vaud on 369 cases and 602 controls. Compared with the lowest tertile of total resveratrol intake, the multivariate odds ratios (OR) were 0.50 for the intermediate and 0.39 for the highest tertile, and the trend in risk was significant. A significant inverse association was observed for resveratrol from grapes (OR = 0.64 and 0.55), but not for wine. The inverse relation between resveratrol and breast cancer risk was not explained by several potential confounding factors, including detailed allowance for alcohol intake, nor attributable to a non-specific favourable effect of fruit on breast cancer risk.

Abstract
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.

Abstract
Alcohol and tobacco consumption are closely correlated and published results on their association with breast cancer have not always allowed adequately for confounding between these exposures. Over 80% of the relevant information worldwide on alcohol and tobacco consumption and breast cancer were collated, checked and analysed centrally. Analyses included 58,515 women with invasive breast cancer and 95,067 controls from 53 studies. Relative risks of breast cancer were estimated, after stratifying by study, age, parity and, where appropriate, women's age when their first child was born and consumption of alcohol and tobacco. The average consumption of alcohol reported by controls from developed countries was 6.0 g per day, i.e. about half a unit/drink of alcohol per day, and was greater in ever-smokers than never-smokers, (8.4 g per day and 5.0 g per day, respectively). Compared with women who reported drinking no alcohol, the relative risk of breast cancer was 1.32 (1.19-1.45, P<0.00001) for an intake of 35-44 g per day alcohol, and 1.46 (1.33-1.61, P<0.00001) for >/=45 g per day alcohol. The relative risk of breast cancer increased by 7.1% (95% CI 5.5-8.7%; P<0.00001) for each additional 10 g per day intake of alcohol, i.e. for each extra unit or drink of alcohol consumed on a daily basis. This increase was the same in ever-smokers and never-smokers (7.1% per 10 g per day, P<0.00001, in each group). By contrast, the relationship between smoking and breast cancer was substantially confounded by the effect of alcohol. When analyses were restricted to 22 255 women with breast cancer and 40 832 controls who reported drinking no alcohol, smoking was not associated with breast cancer (compared to never-smokers, relative risk for ever-smokers=1.03, 95% CI 0.98-1.07, and for current smokers=0.99, 0.92-1.05). The results for alcohol and for tobacco did not vary substantially across studies, study designs, or according to 15 personal characteristics of the women; nor were the findings materially confounded by any of these factors. If the observed relationship for alcohol is causal, these results suggest that about 4% of the breast cancers in developed countries are attributable to alcohol. In developing countries, where alcohol consumption among controls averaged only 0.4 g per day, alcohol would have a negligible effect on the incidence of breast cancer. In conclusion, smoking has little or no independent effect on the risk of developing breast cancer; the effect of alcohol on breast cancer needs to be interpreted in the context of its beneficial effects, in moderation, on cardiovascular disease and its harmful effects on cirrhosis and cancers of the mouth, larynx, oesophagus and liver.

Abstract
An innovative approach was used to define a low-risk diet for colorectal cancer from a multicentric case-control study of 1953 incident cases and 4154 hospital controls from Italy. A logistic regression model was fitted on the reported intake of five macronutrients, and the estimated coefficients were used to compute a diet-related logistic risk score (LRS). The mean of LRS within risk decile ranged from 0.89 to 1.86. Total energy intake and absolute consumption of each macronutrient increased with increasing LRS. In relative terms, however, starch intake showed an almost threefold increase across subsequent score levels, while a decline was observed for unsaturated fat, sugar and protein. Saturated fat consumption remained fairly stable in relative terms. When food groups were considered, bread and cereals dishes, cakes and desserts and refined sugar were positively associated, while the consumption of vegetables, fruit, fish, poultry and olive oils was inversely associated with LRS.

Abstract
Streptococcus pneumoniae hyaluronate lyase (spnHL) is a pathogenic bacterial spreading factor and cleaves hyaluronan, an important constituent of the extra- cellular matrix of connective tissues, through an enzymatic beta-elimination process, different from the hyaluronan degradation by hydrolases in animals. The mechanism of hyaluronan binding and degradation was proposed based on the 1.56 A resolution crystal structure, substrate modeling and mutagenesis studies on spnHL. Five mutants, R243V, N349A, H399A, Y408F and N580G, were constructed and their activities confirmed our mechanism hypothesis. The important roles of Tyr408, Asn349 and His399 in enzyme catalysis were proposed, explained and confirmed by mutant studies. The remaining weak enzymatic activity of the H399A mutant, the role of the free carboxylate group on the glucuronate residue, the enzymatic behavior on chondroitin and chondroitin sulfate, and the small activity increase in the N580G mutant were explained based on this mechanism. A possible function of the C-terminal beta-sheet domain is to modulate enzyme activity through binding to calcium ions.

Abstract
The crystal structure of the engineered monomeric human Cu,ZnSOD triple mutant F50E/G51E/E133Q (Q133M2SOD) is reported at atomic resolution (1.02 A). This derivative has about 20 % of the wild-type activity. Crystals of Q133M2SOD have been obtained in the presence of CdCl2. The metal binding site is disordered, with both cadmium and copper ions simultaneously binding to the copper site. The cadmium (II) ions occupy about 45 % of the copper sites by binding the four histidine residues which ligate copper in the native enzyme, and two further water molecules to complete octahedral coordination. The copper ion is tri-coordinate, and the fourth histidine (His63) is detached from copper and bridges cadmium and zinc. X-ray absorption spectroscopy performed on the crystals suggests that the copper ion has undergone partial photoreduction upon exposure to the synchrotron light. The structure is also disordered in the disulfide bridge region of loop IV that is located at the subunit/subunit interface in the native SOD dimer. As a consequence, the catalytically relevant Arg143 residue is disordered. The present structure has been compared to other X-ray structures on various isoenzymes and to the solution structure of the same monomeric form. The structural results suggest that the low activity of monomeric SOD is due to the disorder in the conformation of the side-chain of Arg143 as well as of loop IV. It is proposed that the subunit-subunit interactions in the multimeric forms of the enzyme are needed to stabilize the correct geometry of the cavity and the optimal orientation of the charged residues in the active channel. Furthermore, the different coordination of cadmium and copper ions, contemporaneously present in the same site, are taken as models for the oxidized and reduced copper species, respectively. These properties of the structure have allowed us to revisit the enzymatic mechanism.

Abstract
The relationship between alcohol consumption and breast cancer risk was investigated using data from a co-operative case-control study conducted in Italy between 1991 and 1994 on 2569 incident, histologically confirmed breast cancer cases and 2588 controls in hospital for acute, non-neoplastic, non-hormone related conditions. Overall, 915 (38%) cases and 1048 (43%) controls were abstainers. Compared with them, the odds ratio (OR), adjusted only for age, was 1.31 (95% confidence interval (CI) 1.13-1.53) for drinkers and became 1.39 (95% CI 1.(1)21-1.60) after correction for measurement error. The multivariate OR was 1.21 for drinkers of < or = 5.87 g/day and 1.23, 1.19, 1.21, 1.41 for drinkers of 5.88-13.40, 13.41-24.55, 24.56-27.60, > 27.60 g/day, respectively. The trend in risk was significant (chi 2 = 12.28, P < 0.0005). The association was apparently stronger in premenopausal women (OR = 1.80 for > 27.60 g/day). Considering the different types of alcoholic beverages (wine, beer, digestives, grappa and other spirits), a significant direct trend in breast cancer risk was seen for wine with an OR of 1.27 (95% CI 1.06-1.53) for the category > 26.34 g/day. The ORs were also above unity for beer, grappa, digestives and spirits drinkers. No appreciable interaction was observed between alcohol drinking and body mass index, smoking, or any other covariate considered. Thus, the present data, based on a validated alcohol consumption questionnaire and on a population characterised by a relatively high alcohol consumption in women, confirmed that alcohol drinking is moderately related to breast cancer risk. If causal, this association could explain 12% (95% CI, 5-19%) of breast cancers in Italy, thus representing one of the major avoidable risk factor for breast cancer.

Abstract
The relationship between alcohol drinking (mainly wine) and risk of colon and rectal cancer was considered in a case-control study conducted between 1991 and 1996 in six Italian centers. Cases were 1,225 patients < 75 years of age with histologically confirmed cancer of the colon and 728 patients with cancer of the rectum; controls were 4,154 patients admitted to hospital for a wide spectrum of acute, nonneoplastic diseases. Compared with never drinkers, the odds ratios (OR) for current drinkers in the higher quintile of total alcohol intake (> 51.82 g ethanol/day) were 1.01 for colon cancer and 0.90 for rectal cancer, and those for ex-drinkers were 1.20 and 1.07, respectively. The OR for wine drinkers in the highest quartile of intake were 1.07 for colon cancer and 0.97 for rectal cancer. No association was found with duration of the habit, time since starting, or age at starting. Among ex-drinkers, no association appeared with time since stopping. No significant heterogeneity was found across strata of age at diagnosis, sex, education, smoking status, physical activity, family history of colorectal cancer, beta-carotene, vitamin C, coffee, total fiber and folate intake, and number of meals per day. No significant association appeared for various intestinal subsites.

Abstract
The relationship between social class indicators, body mass index (BMI), selected life-style habits (alcohol, coffee, maté and tea drinking) and colorectal cancer was investigated in a case-control study conducted between 1993 and 1997 in Córdoba, Argentina, a relatively high mortality area of colorectal cancer. Cases were 190 patients below age 80 years with incident, histologically confirmed colorectal adenocarcinomas, and controls were 393 patients admitted to hospital for a wide spectrum of acute, non-neoplastic disorders. Higher social class, based on occupation of the head of the household, was significantly associated with colorectal cancer risk: the odds ratios (OR) and 95% confidence intervals (95% CI) were 1.9 (1.2-2.9) for intermediate and 2.0 (1.2-3.4) for the highest as compared to the lowest social class individuals. When compared with subjects whose BMI was < 25 kg/m2, the OR was 1.1 (0.7-1.6) for those with BMI 25 to 29 kg/m2, and 1.3 (0.7-2.3) for those > or = 30. In comparison with alcohol abstainers, the OR was 2.8 (1.6-5.1) for drinkers, and there was a significant trend in risk with dose. The association was observed with wine (the most common alcoholic beverage in Argentina), as well as for beer and spirits. The consumption of coffee, maté and tea was not significantly related to colorectal cancer, but the ORs were below unity (0.9 (0.7-1.3) for coffee, 0.9 (0.6-1.2) for maté and 0.8 (0.6-1.2) for tea drinkers). The relationship between social class, alcohol drinking and colorectal cancer were consistent across strata of sex and age. This study confirms that colorectal cancer has positive social class correlates. The association with alcohol drinking is apparently stronger than previously reported, and may be due to the role of chance and/or peculiar correlates of alcohol drinking in this Argentinean population.

Abstract
Data from a multicenter case-control study on breast cancer conducted in Italy were used to analyze the relationship between various types of fibers and breast cancer risk. Cases were 2,569 women with histologically confirmed, incident breast cancer; controls were 2,588 women admitted to the same network of hospitals for acute, nonneoplastic, non-hormone-related diseases. Cases and controls were interviewed between 1991 and 1994 using a validated food frequency questionnaire. The data were modeled through multiple logistic regression, controlling for demographic and reproductive breast cancer risk factors. The continuous odds ratios for the difference between the upper cut point of the fourth and the first quintile of intake were 0.90 [95% confidence interval = 0.82-0.98, p (for trend) < 0.05] for cellulose and 0.94 (95% confidence interval = 0.86-1.02) for soluble fibers. The protection tended to be stronger in premenopausal women. No material association was found for noncellulose polysaccharides and lignin. This study, based on a large data set from various Italian regions, suggests that fiber intake may confer some protection against breast cancer, particularly for cellulose and also for soluble fibers, i.e., those of vegetable origin. This possible protection has been related to an influence of fibers on levels and availability of estrogens and other steroid hormones in breast carcinogenesis.

Abstract
We used data from a case-control study, conducted in Italy on 2,569 incident cases of breast cancer and 2,588 controls, to fit various energy adjustment models in the estimate of the effect of selected nutrients and alcohol on breast cancer risk. When we fit the standard multivariate and residual models, including total energy intake and the different macronutrients one at a time, the odds ratios (OR) related to 100 kcal per day were 0.90 for protein, 0.96 for saturated fat, 0.88 for unsaturated fat, 0.95 for sugar, 1.07 for starch, and 1.06 for alcohol. When we included all of the different sources of calorie intake in a single model with energy sources partitioned, the OR of adding 100 kcal per day was 0.91 for protein, 1.22 for saturated fat, 0.89 for unsaturated fat, 0.98 for sugar, 1.08 for starch, and 1.07 for alcohol. The estimates from the residual models that included various macronutrients separately were similar to those of the extended energy partition model.

Abstract
Until now, it has been unclear whether there are differences in various risk factor profiles for familial gastric cancer, i.e., gastric cancer among subjects with a family history of the disease. A total of 722 gastric cancer patients and 2024 controls were admitted between 1985 and 1992 to a network of hospitals in the Greater Milan area. Of these, 88 cases and 103 controls who reported a family history of gastric cancer in first degree relatives were considered in the present analysis. There was no relationship between gastric cancer risk and tobacco smoking or alcohol drinking. Shorter duration of electrical refrigerator use was related to a nonsignificant increased risk and a high daily meal frequency was associated with an increased gastric cancer risk. Significant direct trends of risk were observed for pasta (odds ratio, OR = 4.20 for the highest versus the lowest tertile), bread (OR, 2.86), red meat (OR, 3.38), and preserved meat (OR, 1.90). Inverse associations were observed for increasing consumption of selected vegetables and fruits, chiefly peppers (OR = 0.31), total fruits (OR, 0.47), and citrus fruits (OR, 0.38). With reference to selected micronutrients, a significant inverse trend in risk with increasing consumption for beta-carotene (OR, 0.27) and ascorbic acid (OR, 0.20) was observed. These results suggest that dietary risk factors for subjects with a family history of gastric cancer in first-degree relatives are not appreciably different from well-established risk factors of the disease in the general population.

Abstract
The Collaborative Group on Hormonal Factors in Breast Cancer has brought together and reanalysed the worldwide epidemiological evidence on breast cancer risk and use of hormonal contraceptives. Original data from 54 studies, representing about 90% of the information available on the topic, were collected, checked and analysed centrally. The 54 studies were performed in 26 countries and include a total of 53,297 women with breast cancer and 100,239 women without breast cancer. The studies were varied in their design, setting and timing. Most information came from case-control studies with controls chosen from the general population; most women resided in Europe or North America and most cancers were diagnosed during the 1980s. Overall 41% of the women with breast cancer and 40% of the women without breast cancer had used oral contraceptives at some time; the median age at first use was 26 years, the median duration of use was 3 years, the median year of first use was 1968, the median time since first use was 16 years, and the median time since last use was 9 years. The main findings, summarised elsewhere, are that there is a small increase in the risk of having breast cancer diagnosed in current users of combined oral contraceptives and in women who had stopped use in the past 10 years but that there is no evidence of an increase in the risk more than 10 years after stopping use. In addition, the cancers diagnosed in women who had used oral contraceptives tended to be less advanced clinically than the cancers diagnosed in women who had not used them. Despite the large number of possibilities investigated, few factors appeared to modify the main findings either in recent or in past users. For recent users who began use before age 20 the relative risks are higher than for recent users who began at older ages. For women whose use of oral contraceptives ceased more than 10 years before there was some suggestion of a reduction in breast cancer risk in certain subgroups, with a deficit of tumors that had spread beyond the breast, especially among women who had used preparations containing the highest doses of oestrogen and progestogen. These findings are unexpected and need to be confirmed. Although these data represent most of the epidemiological evidence on the topic to date, there is still insufficient information to comment reliably about the effects of specific types of oestrogen or of progestogen. What evidence there is suggests, however, no major differences in the effects for specific types of oestrogen or of progestogen and that the pattern of risk associated with use of hormonal contraceptives containing progestogens alone may be similar to that observed for preparations containing both oestrogens and progestogens. On the basis of these results, there is little difference between women who have and have not used combined oral contraceptives in terms of the estimated cumulative number of breast cancers diagnosed during the period from starting use up to 20 years after stopping. The cancers diagnosed in women who have used oral contraceptives are, however, less advanced clinically than the cancers diagnosed in never users. Further research is needed to establish whether the associations described here are due to earlier diagnosis of breast cancer in women who have used oral contraceptives, to the biological effects of the hormonal contraceptives or to a combination of both. Little information is as yet available about the effects on breast cancer risk of oral contraceptive use that ceased more than 20 years before and as such data accumulate it will be necessary to re-examine the worldwide evidence.

Abstract
BACKGROUND The reproducibility and validity of alcohol consumption has not been adequately studied, particularly in mediterranean countries, where alcohol drinking is a widespread habit, especially during meals. METHODS We compared alcohol consumption measured by two interviewer-administered food frequency questionnaires (FFQ) with average intake derived from two 7-day dietary (7-DD) records (the reference method) on 395 volunteers. Different types of alcoholic beverages were considered separately in order to verify the ability of the questionnaire to assess detailed patterns of alcohol intake. RESULTS A satisfactory level of reproducibility and validity of the pattern of alcohol consumption across different levels and types of alcoholic beverage intake was observed. The reproducibility of wine and total alcohol intake showed correlation coefficients > 0.75 in both sexes. The validity was somewhat higher for wine (around 0.70) than for other alcoholic beverages and total alcohol intake. This is probably accounted for by the more regular pattern of wine consumption during the year as compared to other alcoholic beverages (beer, grappa, etc) which are more strongly influenced by seasonal and daily variations. However, about 30% of abstainers according to FFQ were drinkers by the reference method. The opposite was observed in only 4% of subjects. CONCLUSION The FFQ is a reliable and valid instrument for collecting alcohol intake in regular drinkers. Lower validity in irregular drinkers may be due to seasonal variation and/or inadequacy of the FFQ to capture irregular patterns of consumption and/or inadequacy of the average of two 7-DD as a reference method. Furthermore, a considerable degree of misclassification was observed between non-drinkers and moderate drinkers.

Abstract
BACKGROUND The association between risk of breast cancer and dietary fat and intakes of other energy sources remains controversial. The Italian population offers special opportunities to assess the influence of high intakes of unsaturated fat and starch and, because the population has low awareness of diet and cancer issues, there is less scope for recall bias. We have assessed the relations of various macronutrient intakes with risk of breast cancer. METHODS In this case-control study, 2569 women with incident breast cancer (median age 55 years) and 2588 control women (median age 56 years) in hospital with acute, non-neoplastic diseases, were interviewed in six different areas of Italy between 1991 and 1994. A validated food-frequency questionnaire was used. It included questions on 78 foods and recipes grouped into six sections, as well as specific questions on individual fat intake pattern. FINDINGS The risk of breast cancer decreased with increasing total fat intake (trend p 0.01) whereas the risk increased with increasing intake of available carbohydrates (trend p = 0.002). The odds ratios for women in the highest compared with the lowest quintile of energy-adjusted intake were 0.81 for total fat and 1.30 for available carbohydrates. Starch was the chief contributor to the positive association with available carbohydrates. High intakes of polyunsaturated and unsaturated fatty acids (i.e., polyunsaturated fatty acids plus oleic acid) were associated with a decreased risk of breast cancer (odds ratios for highest vs lowest quintile 0.70 and 0.74, respectively). Conversely, the intakes of saturated fatty acids, protein, and fibre were not significantly associated with breast-cancer risk. INTERPRETATION This case-controls study shows that unsaturated fatty acids protect against breast cancer, possibly because intake of these nutrients is closely correlated with a high intake of raw vegetables. The findings also suggest a possible risk in southern European populations, of reliance on a diet largely based on starch.

Abstract
Using data from a case-control study conducted between 1985 and 1992 in northern Italy on 828 cases of colon cancer, 498 cases of rectal cancer and 2,024 controls in hospital for acute, non-neoplastic, non-digestive tract disorders, we estimated the percent population attributable risk (PAR) for colorectal cancer in relation to beta-carotene, vitamin C (as markers of a diet rich in fruit and vegetables), red meat and seasoning fat intake, daily meal frequency and family history of the disease. On the basis of multivariate odds ratios, adjusted for total calorie intake, a low intake of beta-carotene accounted for 39% of all the cases and a low intake of vitamin C for 14%. These two micronutrients together explained 43% of all colorectal cancer cases in this population. A high frequency of intake of red meat consumption explained 17% of all cases, and a high score of seasoning fats 4%. A higher daily meal frequency was responsible for 13% of the cases, and these 5 dietary factors together explained 63% of colorectal cancer cases in this population. Family history of colorectal cancer accounted for 4% of all cases. These estimates were similar for colon and rectal cancers separately, in males and females, and in younger and elderly subjects, except for seasoning fats and family history, whose PARs were apparently greater for colon cancer and at younger age. Thus, even though available dietary data were limited in several aspects, and the PAR estimates were based on somewhat arbitrary assumptions regarding the exposure distribution, about two-thirds of all colorectal cancers in this population could be explained in terms of a few risk factors or risk indicators considered. This would correspond to the avoidance of a large proportion of the over 18,000 deaths from colorectal cancer registered per year in the whole of Italy.

Abstract
The validity of a 77-item food-frequency questionnaire (FFQ) developed for a multicenter case-control study on diet and cancer in Italy was assessed. Trained interviewers administered the same FFQ to 452 volunteers from three Italian provinces (Pordenone, Genoa, and Forli) completed in two different seasons, at an interval of 3 to 10 months. For 395 (130 males, 265 females; median age = 52 years; range = 35 to 69 years) volunteers, two 7-day dietary (7-DD) records were available. Average intake obtained by means of the FFQ was overestimated by approximately 18% in comparison with the corresponding values based on the two 7-DD records (reference method). Pearson partial correlation coefficients, adjusted for total energy intake between the nutrient intakes assessed by the FFQ and reference method, ranged from 0.19 for vegetable fat to 0.64 for sugar (median value r = 0.46). The unadjusted deattenuated coefficients, which took into account the interindividual variability of consumption, estimated by means of the two 7-DD records, ranged from 0.29 for vegetable fat to 0.72 for starch (median value r = 0.54). The proportion of subjects correctly classified within the lowest two quintiles ranged between 59% for vegetable fat and vitamin E, and 96% for alcohol, and those correctly classified within the highest two quintiles ranged between 44% for vegetable fat and 94% for alcohol. The average proportion of subjects correctly classified within one quintile was 73%. These data indicate that this FFQ provides valid estimates of intakes for major nutrients, comparable to those reported from other studies in North America and other European countries.

Abstract
The increasing interest in obtaining model-based estimates of attributable risk (AR) and corresponding confidence intervals, in particular when more than one risk factor and/or several confounding factors are jointly considered, led us to develop a program based on the procedure described by Benichou and Gail for case-control data. This program is structured as an SAS-macro. It is suited to analysis of the relationship between risk factors and disease in case-control studies with simple random sampling of controls, in terms of relative risks and ARs, by means of unconditional logistic regression analysis. The variance of the AR is obtained by the delta method and is based on three components, namely, (i) the variance-covariance matrix of the vector of the estimated probabilities of belonging to joint levels of the exposure and confounding factors conditional on being a case, (ii) the variance-covariance matrix of the odds ratio parameter estimates from the logistic model, and (iii) the covariances between these probability and parameter estimates. Only a limited number of commands is requested from the user (i.e., the name of the work file and the names of the variables considered). The estimated relative risks for all the factors included in the model, the attributable risk for the exposure factor under consideration, and the corresponding 95% confidence intervals are given as outputs by the macro. Computational problems, if any, may arise for large numbers of covariates because of the resulting large size of vectors and matrices. The macro was tested for reliability and consistency on published data sets of case-control studies.

Abstract
To investigate the relation between selected micronutrients and breast cancer risk, we conducted a case-control study of breast cancer between June 1991 and April 1994 in 6 Italian areas. The study included 2569 women admitted to the major teaching and general hospitals of the study areas with histologically confirmed incident breast cancer and 2588 control women with no history of cancer, who were admitted to hospitals in the same catchment areas for acute, non-neoplastic, nongynecological conditions unrelated to hormonal or digestive tract diseases or to long-term modifications of the diet. Dietary habits, including alcoholic beverage consumption, were investigated using a validated food frequency questionnaire, including 78 foods or food groups, several types of alcoholic beverages, some "fat intake pattern" questions and some open sections for foods consumed frequently by the subject and not reported in the questionnaire. To control for potential confounding factors, several multiple logistic regression models were used. When major correlates, energy intake and the mutual confounding effect of the various micronutrients were taken into account, beta-carotene, vitamin E and calcium showed a significant inverse association with breast cancer risk. The estimated odds ratios of the 5th quintile compared to the lowest one were 0.84 for beta-carotene, 0.75 for vitamin E and 0.81 for calcium. No significant association emerged for retinol, vitamin C, thiamin, riboflavin, iron and potassium. Our results suggest that a diet rich in several micronutrients, particularly beta-carotene, vitamin E and calcium, may be protective against breast cancer.

Abstract
We studied the influence of age, sex, education and time between interviews on the reproducibility of a semi-quantitative food frequency questionnaire (FFQ) developed in Italy for a case-control study on cancers of the breast and digestive tract. The questionnaire had been administered twice to 452 Italian men and women and included the weekly consumption of 77 food items or groups of foods, seven summary questions and three questions on some general dietary habits. Spearman correlation coefficients for the 77 dietary items plus the seven summary questions did not differ between males (median 0.61) and females (median 0.58), volunteers younger than 50 years (median 0.58) and aged 50 or more (median 0.59), volunteers with fewer than 10 years of education (median 0.58) and with 10 or more (median 0.59). A slightly higher Spearman correlation coefficient was found when the two interviews were conducted 5-6 months apart (median 0.60) or more than 6 (median 0.59) than when less than 5 (median 0.55). Similarly, Pearson correlation coefficients for the intake of 27 nutrients or micronutrients, plus caloric intake, computed from the FFQ showed no differences between males (median 0.65) and females (median 0.64), two age groups (median 0.67 for subjects aged < 50 years and 0.65 for those aged > or = 50), and two educational levels (median 0.68 for < 10 years and 0.65 for > or = 10 years). The median Pearson correlation coefficient for nutrients was slightly higher for those subjects who were interviewed with the planned interval (5-6 months, median 0.71) than when the interval was shorter (median 0.57) or longer (median 0.64).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The relationship between past contraceptive method use and risk of ectopic pregnancy has been analyzed in a case-control study conducted in Milan, Italy. Cases were 158 women with diagnosis of ectopic pregnancy confirmed by laparoscopy or laparotomy, admitted to a network of university and general hospitals of Milan. The first control group (obstetric controls) included 243 women who gave birth at term (more than 37 weeks' gestation) to healthy infants at the same hospitals where the cases had been identified. The second control group (non-obstetric controls) was a random sample of 158 women admitted to the same network of hospitals where cases had been identified for diseases other than malignant, hormonal, or gynecological in origin. A total of 37 (23%) cases, 21 (9%) obstetric and 24 (15%) non-obstetric controls reported ever IUD use. The corresponding relative risk, RR, of ectopic pregnancy was 3.5 (95% CI 1.3-4.6) when non-obstetric subjects were considered as control group. The risk of ectopic pregnancy increased with duration of IUD use: in comparison with obstetric and non-obstetric controls, the RR were 2.3 and 2.0 for users for less than 2 years and 4.3 and 2.6 for longer users. There was no clear relation between time since last IUD use and risk of ectopic pregnancy, and no evidence of a decline of risk with increasing time since stopping use.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We used data from the 1983 Italian National Health Survey, based on 58,462 adults ages 25 years and over who are representative of the general Italian population, to compare the prevalence of 16 major chronic diseases or groups of diseases in alcohol abstainers (ex- and never-drinkers combined) and current drinkers. We found elevated odds ratios among alcohol abstainers for diabetes, hypertension, myocardial infarction, other heart diseases, anemias, gastroduodenal ulcer, cholelithiasis, liver cirrhosis, urolithiasis, and renal insufficiency.
