Enhanced structural and magnetic properties of fcc colloidal crystals of cobalt nanoparticles.

We report the elaboration of supercrystals made up of dodecanoic acid-coated 8.1 nm-Co nanocrystals with controlled supercrystallinity, morphology and magnetic properties. Supercrystal growth is controlled using a solvent-mediated ligand-ligand interaction strategy. Either face-centered cubic supercrystalline films or single colloidal crystals composed of cobalt nanocrystals are obtained. The change in supercrystal morphology is explained by Flory-type solvation theory using Hansen solubility colloidal parameters. The use of the same batch of Co nanocrystals for the fabrication of supercrystalline films and colloidal crystals enables accurate comparative structural and magnetic studies using (high-resolution) transmission electron microscopy, field emission gun scanning electron microscopy, grazing incidence small-angle X-ray scattering and vibrating sample magnetometry. The nearest neighbor distance between nanoparticles is interpreted using theoretical models proposed in the literature. We evidence the increase in both geometric anisotropy and magnetic dipolar interactions for colloidal crystals compared to supercrystalline films.

Lifestyle and biological factors influence the relationship between mental health and low-grade inflammation.

Mental health modulates the risk of common chronic conditions. Although inflammation is thought to partly explain this link, its relation with mental health is still unclear and largely unexplored. We investigated three scales assessing psychological resilience (CD-RISC), depression symptoms (PHQ9-6) and mental wellbeing (SF36-MCS) in an Italian adult population cohort (Nmax = 16,952). This showed a slightly higher frequency of men, more educated and younger participants, compared to samples with incomplete questionnaires. We performed stepwise generalized linear models to test the association between each scale and INFLA-score, a composite blood-based inflammation index. At each step, a class of potential mediators was included in the model, namely health conditions, lifestyle factors, or both (full model). Full model analysis was also conducted on single blood markers involved in the inflammatory process. In the baseline model, we observed significant associations of PHQ9-6 (standardized ß(SE) = 0.024(0.009), p = 8.9 × 10-3) and SF36-MCS (ß(SE) = -0.021(0.008), p = 7 × 10-3) with INFLA-score. These associations survived adjustment for health conditions but not for lifestyle factors, which explained 81% and 17% of the association with PHQ9-6 and SF36-MCS. Significant associations (p < 4.2 × 10-3) after mediator adjustment were observed for single low-grade inflammation markers, including platelet distribution width (with PHQ9-6 and CD-RISC), granulocyte- and neutrophil-to-lymphocyte ratios, monocyte and lymphocyte fractions (with SF36-MCS). After imputation of missing data, we observed substantially consistent associations. These findings suggest that the relationship between mental health and low-grade inflammation is largely influenced by lifestyle. However, the associations with specific biomarkers related to inflammation are partly independent and might be explained by biological factors.

Consumption of whole grain food and its determinants in a general Italian population: Results from the INHES study.

BACKGROUND AND AIMS: Whole grain (WG) food consumption is associated with lower risk of cardiovascular disease, cancer and neurological diseases. The aim of this study was to assess the consumption of WG food and its major demographic, socioeconomic, psychosocial and behavioral determinants in a general Italian population. METHODS AND RESULTS: Data were from the Italian Nutrition & Health Survey (INHES), a telephone-based survey established in 2010-2013 including 9422 participants aged ≥5 years from all over Italy. WG food intake was assessed by the European Food Propensity Questionnaire and included bread, pasta, breakfast cereals, biscuits and WG soups. WG consumption was categorized as none, occasional (<1 time/week) and regular (≥1 time/week). Overall, 26.9% of the sample reported a regular consumption of WG food (27.2% of adults aged 20-97 y, and 21.9% of children/adolescents aged 5-19 y). In both age-groups, the major food source contributing to total WG intake was WG bread followed by WG pasta. Among adults, greater consumption of WG was associated with healthier lifestyle (e.g. sport activity), and higher educational level. Eating meals outside of the house in adults, and spending >2 h/day watching TV in children/adolescents were inversely associated with WG intake. CONCLUSIONS: The percentage of WG consumers in Italy in 2010-2013 appears to be quite low and still below that recorded in other countries of Europe where consumption is frequently over 50 percent. WG consumption is likely to be influenced by socioeconomic status and is associated with a number of psychosocial factors, meal patterns and eating-related behaviors.

Impact of combined healthy lifestyle factors on survival in an adult general population and in high-risk groups: prospective results from the Moli-sani Study.

BACKGROUND: There is poor knowledge on the association between combined lifestyles with mortality risk among individuals at high risk, and little is known on the biological mechanisms that could be on the pathway. METHODS: Longitudinal analysis on 22 839 individuals from the Moli-sani Study (Italy, 2005-2010). Among them, we identified 5200 elderly individuals (≥65 year), 2127 subjects with diabetes and 1180 with cardiovascular disease (CVD) at baseline. A healthy lifestyle score (HLS) was calculated, allocating 1 point for each of the following: abstention from smoking; adherence to Mediterranean diet; physical activity; absence of abdominal obesity. Hazard ratios (HR) with 95% confidence intervals (95%CI) were calculated by multivariable Cox regression and competing risk models. RESULTS: During 8.2 years of follow-up, 1237 deaths occurred. In the general population, adherence to all four healthy lifestyles, compared with none or 1, was associated with lower risk of all-cause (HR = 0.53; 95%CI:0.39-0.72), CVD (HR = 0.54; 0.32-0.91), cancer (HR = 0.62; 0.39-1.00) and mortality from other causes (HR = 0.39; 0.19-0.81). A 1-point increase in HLS was associated with 20%, 22% and 24% lower risk of total mortality among the elderly, in subjects with diabetes or CVD, respectively. Traditional (e.g. blood lipids), inflammatory (e.g. C-reactive protein) and novel biomarkers (e.g. markers of cardiac damage) accounted for up to 24% of the association of HLS with all-cause mortality risk in the general population. CONCLUSIONS: The impact of combined four healthy lifestyles on survival was considerable, both in the general population and among high-risk subgroups. Inflammatory and novel biomarkers of CVD risk explained a substantial proportion of this association.

Diet and primary prevention of stroke: Systematic review and dietary recommendations by the ad hoc Working Group of the Italian Society of Human Nutrition.

BACKGROUND AND AIMS: To systematically review the latest evidence on established and emerging nutrition-related risk factors for incidence of and mortality from total, ischemic and haemorrhagic strokes. The present review was conducted in the framework of the work carried out through 2015 and 2016 for the preparation of the Italian Guidelines for the Prevention and Treatment of Stroke, 8th Edition, by ISO-SPREAD (Italian Stroke Organization and the Stroke Prevention and Educational Awareness Diffusion). METHODS AND RESULTS: Systematic review of articles focused on primary prevention of stroke published between January 2013 to May 2016 through an extensive search of the literature using MEDLINE/PUBMED, EMBASE and the Cochrane Library. Articles were ranked according to the SIGN methodology while the GRADE system was used to establish the strength of recommendations. As a result of our literature search, we examined 87 meta-analyses overall (mainly of prospective studies), a few isolated more recent prospective studies not included in the meta-analyses, and a smaller number of available randomized controlled trials and case-control studies. Based on the analysis of the above articles, 36 Syntheses of the available evidence and 36 Recommendations were eventually prepared. The present document was developed by organizing the available evidence into three individual areas (nutrients, food groups and dietary patterns) to provide a systematic and user-friendly overview of the available evidence on the relationship between nutrition and primary prevention of stroke. Yet analysis of foods and food patterns allowed translating the information about nutrients in a tool more amenable to use in daily life also in the light of the argument that people eat foods rather than nutrients. CONCLUSIONS: The present literature review and dietary recommendations provide healthcare professionals and all interested readers with a useful overview for the reduction of the risk of total, ischemic and haemorrhagic stroke through dietary modifications.

Serum vitamin D deficiency and risk of hospitalization for heart failure: Prospective results from the Moli-sani study.

BACKGROUND AND AIMS: Evidence indicates that Vitamin D deficiency may be associated with increased risk of cardiovascular disease, although findings on risk of heart failure (HF) are controversial. We investigated the relationship between serum Vitamin D and the incidence of hospitalization for HF in a large prospective cohort of Italian adults. METHODS AND RESULTS: 19,092 (49% men, age range 35-99 years) HF-free individuals from the Moli-sani study, with complete data on serum Vitamin D (25-hydroxyvitamin) levels and incident hospitalized HF, were analysed. The cohort was followed up for a median of 6.2 years. Baseline serum Vitamin D levels were categorized in deficient (<10 ng/mL), insufficient (10-29 ng/mL), and normal (≥30 ng/mL) Incident cases of hospitalization for HF were identified by linkage with the regional hospital discharge registry. Hazard ratios (HRs) were calculated using Cox-proportional hazard models. The prevalence of normal, insufficient or deficient levels of Vitamin D was 12.2%, 79.6% and 8.2%, respectively. During follow-up, 562 admissions to hospital for HF were identified. The incidence of HF was 1.6%, 2.9% and 5.3%, respectively in subjects with normal, insufficient and deficient levels of Vitamin D. After multivariable analysis, individuals with deficiency of Vitamin D had a higher risk of hospitalization for HF (HR: 1.61, 95%CI: 1.06-2.43) than those with normal levels. Further adjustment for subclinical inflammation did not substantially change the association between Vitamin D deficiency and HF. CONCLUSION: Deficiency of Vitamin D was associated, independently of known HF risk factors, with an increased risk of hospitalization for HF in an Italian adult population.

Mediterranean-type diet is associated with higher psychological resilience in a general adult population: findings from the Moli-sani study.

BACKGROUND/OBJECTIVE: Psychological resilience is a measure of stress coping ability and has been associated with favourable health outcomes. While evidence on the relationship of dietary habits with a number of psychosocial conditions is available, there is lack of studies on their association with psychological resilience in a general adult population. SUBJECTS/METHODS: Cross-sectional analysis on 10 812 subjects recruited within the cohort of the Moli-sani study (2005-2010). Psychological resilience was measured by the 25-item Connor-Davidson Psychological Resilience Scale. Food intake was recorded by the EPIC food frequency questionnaire and adherence to Mediterranean diet was appraised by both a Greek Mediterranean diet score and an Italian Mediterranean Index. Empirically derived dietary patterns were obtained by principal factor analysis. Multivariable linear regression analysis (95%CI) was used to test the association between dietary scores and psychological resilience. RESULTS: Higher adherence to Mediterranean-type diets or consumption of a vegetable-based dietary pattern (obtained from principal factor analysis) were positively associated with psychological resilience (ß=0.43; 95%CI: 0.19-0.66, ß=0.92; 0.69-1.16, and ß=1.18; 0.93-1.44, for Greek Mediterranean diet score, Italian Mediterranean Index and the 'Olive oil and vegetables pattern', respectively). Dietary polyphenol or antioxidant intakes and greater variety in fruit and vegetable consumption were also positively associated with psychological resilience, while the associations with Western-like diets were weak. CONCLUSIONS: In conclusion, Mediterranean diet, vegetable-based dietary patterns and better diet quality were all positively associated with higher psychological resilience, whereas Western-type diets were not.

Fish intake is associated with lower cardiovascular risk in a Mediterranean population: Prospective results from the Moli-sani study.

BACKGROUND AND AIMS: Fish consumption reportedly reduces the risk of heart disease, but the evidence of cardiovascular advantages associated with fish intake within Mediterranean cohorts is limited. The aim of this study was to test the association between fish intake and risk of composite coronary heart disease (CHD) and stroke in a large population-based cohort adhering to Mediterranean Diet. METHODS AND RESULTS: Prospective analysis on 20,969 subjects free from cardiovascular disease at baseline, enrolled in the Moli-sani study (2005-2010). Food intake was recorded by the Italian version of the EPIC food frequency questionnaire. Hazard ratios were calculated by using multivariable Cox-proportional hazard models. During a median follow-up of 4.3 years, a total of 352 events occurred (n of CHD = 287 and n of stroke = 66). After adjustment for a large panel of covariates, fish intake ≥4 times per week was associated with 40% reduced risk of composite CHD and stroke (HR = 0.60; 95%CI 0.40-0.90), and with 40% lower risk of CHD (HR = 0.60; 95%CI 0.38-0.94) as compared with subjects in the lowest category of intake (<2 times/week). A similar trend of protection was found for stroke risk although results were not significant (HR = 0.62; 95%CI 0.26-1.51). When fish types were considered, protection against the composite outcome and CHD was confined to fatty fish intake. CONCLUSIONS: Fish intake was associated with reduced risk of composite fatal and non-fatal CHD and stroke in a general Mediterranean population. The favourable association was likely to be driven by fatty fish.

Food group consumption in an Italian population using the updated food classification system FoodEx2: Results from the Italian Nutrition & HEalth Survey (INHES) study.

BACKGROUND AND AIM: Dietary habits evolve over time, being influenced by many factors and complex interactions. This work aimed at evaluating the updated information on food group consumption in Italy. METHODS AND RESULTS: A total of 8944 (4768 women and 4176 men) participants aged >18 years from all over Italy recruited in 2010-13 (Italian Nutrition & HEalth Survey, INHES) was analyzed. The recruitment was performed using computer-assisted-telephone-interviewing and one-day 24-h dietary recall retrieved from all participants. The updated, second version, of FoodEx2 food classification system was applied to extract data on food group consumption. The participation rate was 53%; 6.2% of the participants declared to follow a special diet, the most prevalent being hypo-caloric diets (55.7% of special diets). Men compared to women presented significantly higher intakes of "grains and grain-based products", "meat and meat products", "animal and vegetable fats and oils and primary derivatives" and "alcoholic beverages" (P for all<0.001); moreover, men had lower intakes of "milk and dairy products", "water and water-based beverages" and "products for non-standard diets, food imitates and food supplements" (P for all<0.001). Differences in food group intake among age groups, geographical regions and educational level groups were also identified (P for all<0.05). CONCLUSIONS: Data on the consumption of more than 70 food groups and sub-groups were illustrated in different strata. The present analysis could be considered as an updated source of information for future nutrition research in Italy and in the EU.

Association of pasta consumption with body mass index and waist-to-hip ratio: results from Moli-sani and INHES studies.

BACKGROUND/OBJECTIVES: Pasta as a traditional component of Mediterranean diet (MeD) in Italy has not been studied in detail in the management of body weight. This study aimed at evaluating the association of pasta intake with body mass index (BMI) and waist-to-hip ratio, in two large epidemiological datasets. SUBJECTS/METHODS: A total of 14 402 participants aged ⩾35 years randomly recruited from the general population of the Molise region (Moli-sani cohort) and 8964 participants aged >18 years from all over Italy (Italian Nutrition & HEalth Survey, INHES) were separately analyzed. The European Prospective Investigation into Cancer and Nutrition (EPIC)-food frequency questionnaire and one 24-h dietary recall were used for dietary assessment. Weight, height, waist and hip circumference were measured in Moli-sani or self-reported in INHES. Residuals methodology corrected for either total energy intake or body weight was used for the analysis of pasta intake. RESULTS: Higher pasta intake was associated with better adhesion to MeD in both genders (P for both<0.001). In the Moli-sani study, after multivariable analysis, pasta-energy residuals were negatively associated with BMI in women but not in men (ß-coef=-0.007, P=0.003 for women and ß-coef=-0.001, P=0.58 for men). When pasta intake-body weight residuals were used, pasta intake was significantly and negatively associated with BMI in crude and multi-adjusted models (including adhesion to MeD) in both genders and Moli-sani and INHES studies (for all ß-coef<0, P<0.05). In the Moli-sani study, pasta-body weight residuals were significantly and negatively associated with waist and hip circumference and waist-to-hip ratio (for all ß-coef<0, P<0.05). CONCLUSIONS: As a traditional component of MeD, pasta consumption was negatively associated with BMI, waist circumference and waist-to-hip ratio and with a lower prevalence of overweight and obesity.

Moderate influenza vaccine effectiveness against hospitalisation with A(H3N2) and A(H1N1) influenza in 2013-14: Results from the InNHOVE network.

We conducted a multicentre test negative case control study to estimate the 2013-14 influenza vaccine effectiveness (IVE) against hospitalised laboratory confirmed influenza in 12 hospitals in France, Italy and Spain. We included all ≥18 years hospitalised patients targeted by local influenza vaccination campaign reporting an influenza-like illness within 7 days before admission. We defined as cases patients RT-PCR positive for influenza and as controls those negative for all influenza virus. We used a logistic regression to calculate IVE adjusted for country, month of onset, chronic diseases and age. We included 104 A(H1N1)pdm09, 157 A(H3N2) cases and 585 controls. The adjusted IVE was 42.8% (95%CI: 6.3;65;0) against A(H1N1)pdm09. It was respectively 61.4% (95%CI: -1.9;85.4), 39.4% (95%CI: -32.2;72.2) and 19.7% (95%CI:-148.1;74.0) among patients aged 18-64, 65-79 and ≥80 years. The adjusted IVE against A(H3N2) was 38.1% (95%CI: 8.3;58.2) overall. It was respectively 7.8% (95%CI: -145.3;65.4), 25.6% (95%CI: -36.0;59.2) and 55.2% (95%CI: 15.4;76.3) among patients aged 18-64, 65-79 and ≥80 years. These results suggest a moderate and age varying effectiveness of the 2013-14 influenza vaccine to prevent hospitalised laboratory-confirmed influenza. While vaccination remains the most effective prevention measure, developing more immunogenic influenza vaccines is needed to prevent severe outcomes among target groups.

Effects of moderate beer consumption on health and disease: A consensus document.

A large evidence-based review on the effects of a moderate consumption of beer on human health has been conducted by an international panel of experts who reached a full consensus on the present document. Low-moderate (up to 1 drink per day in women, up to 2 in men), non-bingeing beer consumption, reduces the risk of cardiovascular disease. This effect is similar to that of wine, at comparable alcohol amounts. Epidemiological studies suggest that moderate consumption of either beer or wine may confer greater cardiovascular protection than spirits. Although specific data on beer are not conclusive, observational studies seem to indicate that low-moderate alcohol consumption is associated with a reduced risk of developing neurodegenerative disease. There is no evidence that beer drinking is different from other types of alcoholic beverages in respect to risk for some cancers. Evidence consistently suggests a J-shaped relationship between alcohol consumption (including beer) and all-cause mortality, with lower risk for moderate alcohol consumers than for abstainers or heavy drinkers. Unless they are at high risk for alcohol-related cancers or alcohol dependency, there is no reason to discourage healthy adults who are already regular light-moderate beer consumers from continuing. Consumption of beer, at any dosage, is not recommended for children, adolescents, pregnant women, individuals at risk to develop alcoholism, those with cardiomyopathy, cardiac arrhythmias, depression, liver and pancreatic diseases, or anyone engaged in actions that require concentration, skill or coordination. In conclusion, although heavy and excessive beer consumption exerts deleterious effects on the human body, with increased disease risks on many organs and is associated to significant social problems such as addiction, accidents, violence and crime, data reported in this document show evidence for no harm of moderate beer consumption for major chronic conditions and some benefit against cardiovascular disease.

Flavonoid and lignan intake in a Mediterranean population: proposal for a holistic approach in polyphenol dietary analysis, the Moli-sani Study.

BACKGROUND/OBJECTIVES: The objective of this study is to extract and assess data on the dietary intake of flavonoids and lignans in a healthy free-living Mediterranean population, using newly updated harmonized European Union food composition data. This work also aimed at analyzing in a holistic way the total content of the diet in major classes of polyphenols. SUBJECTS/METHODS: Six thousand nine hundred and eighty-one men and 7048 women (aged ⩾ 35 years) of the Moli-sani cohort, randomly recruited from the general population, were analyzed. The European Prospective Investigation into Cancer (EPIC) and Nutrition-Food Frequency Questionnaire was used for dietary assessment. The polyphenol content of each food group was evaluated using Eurofir BioActive Substances in Food Information System and the United States Department of Agriculture food composition tables (FCTs), when data were missing. Flavonol, flavone, flavanone, flavanol, anthocyanin, isoflavone and lignan intakes were calculated and polyphenol antioxidant content (PAC) score (-28, 28) constructed, to assess the total content of the diet in these nutrients. RESULTS: Seasonal and citrus fruits, leafy, grain, pod and root vegetables, and onions and garlic accounted for different proportions (11-70%) of the total intake of different polyphenols. Within the Moli-sani population, men or older, or no/former smokers, or physically active or obese/overweight individuals presented higher consumption of flavonoids, lignans and PAC score (P for all <0.01). Multiple regression analysis showed that PAC score and its seven components were positively associated with Mediterranean diet (MeD) adherence in both genders (ß-coefficient >0, P<0.001). In addition, 1 unit increase in PAC score was associated with 7.1-7.8% increase in the likelihood of high MeD adherence (P<0.001). CONCLUSIONS: The intake of flavonoids and lignans in an European Union population was calculated using harmonized European Union FCT data. In addition, a holistic approach in dietary analysis of polyphenol intake was proposed.

2012/13 influenza vaccine effectiveness against hospitalised influenza A(H1N1)pdm09, A(H3N2) and B: estimates from a European network of hospitals.

While influenza vaccines aim to decrease the incidence of severe influenza among high-risk groups, evidence of influenza vaccine effectiveness (IVE) among the influenza vaccine target population is sparse. We conducted a multicentre test-negative case-control study to estimate IVE against hospitalised laboratory-confirmed influenza in the target population in 18 hospitals in France, Italy, Lithuania and the Navarre and Valencia regions in Spain. All hospitalised patients aged ≥18 years, belonging to the target population presenting with influenza-like illness symptom onset within seven days were swabbed. Patients positive by reverse transcription polymerase chain reaction for influenza virus were cases and those negative were controls. Using logistic regression, we calculated IVE for each influenza virus subtype and adjusted it for month of symptom onset, study site, age and chronic conditions. Of the 1,972 patients included, 116 were positive for influenza A(H1N1)pdm09, 58 for A(H3N2) and 232 for influenza B. Adjusted IVE was 21.3% (95% confidence interval (CI): -25.2 to 50.6; n=1,628), 61.8% (95% CI: 26.8 to 80.0; n=557) and 43.1% (95% CI: 21.2 to 58.9; n=1,526) against influenza A(H1N1) pdm09, A(H3N2) and B respectively. Our results suggest that the 2012/13 IVE was moderate against influenza A(H3N2) and B and low against influenza A(H1N1) pdm09.

Decline of the Mediterranean diet at a time of economic crisis. Results from the Moli-sani study.

BACKGROUND AND AIMS: Adherence to Mediterranean diet (MD) is reportedly declining in the last decades. We aimed to investigate the adherence to MD over the period 2005-2010 and exploring the possible role of the global economic crisis in accounting for the changing in the dietary habits in Italy. METHODS AND RESULTS: Cross-sectional analysis in a population-based cohort study which randomly recruited 21,001 southern Italian citizens enrolled within the Moli-sani study. Food intake was determined by the Italian EPIC food frequency questionnaire. Adherence to MD was appraised by the Italian Mediterranean Index (IMI). A wealth score was derived to evaluate the economic position and used together with other socioeconomic indicators. Highest prevalence of adherence to MD was observed during the years 2005-2006 (31.3%) while the prevalence dramatically fell down in the years 2007-2010 (18.3%; P<0.0001). The decrease was stronger in the elderly, less affluent groups, and among those living in urban areas. Accordingly, we observed that in 2007-2010 socioeconomic indicators were strongly associated with higher adherence to MD, whereas no association was detected in the years before the economic crisis began; both wealth score and education were major determinants of high adherence to MD with 31% (95%CI: 18-46%) higher adherence to this pattern within the wealthier group compared to the less affluent category. CONCLUSION: Adherence to MD has considerably decreased over the last few years. In 2007-2010 socioeconomic indicators have become major determinants of adherence to MD, a fact likely linked to the economic downturn.

Mushroom and dietary selenium intakes in relation to fasting glucose levels in a free-living Italian adult population: the Moli-sani Project.

AIM: Mushrooms are known to be a major food source of selenium, a mineral associated with diabetes prevalence. This study aimed to evaluate the relationship between mushroom and dietary selenium intakes and blood glucose levels in a free-living adult Italian population. METHODS: A total of 6879 men and 6891 women (aged 53.1±11.0years) with neither diabetes nor on special diets were analyzed from the population randomly recruited for the Moli-sani study. The European Prospective Investigation into Cancer and Nutrition (EPIC) food frequency questionnaire was used for dietary assessment. Fasting blood glucose (FBG) levels were measured from fasting serum samples, and diabetes prevalence was determined according to American Diabetes Association diagnostic criteria. RESULTS: In men, an increase of one (30-g) portion/week in mushroom consumption was associated with a 0.43-0.55mmol/L increase in FBG at different levels of adjustment (P<0.05). In both men and women, dietary selenium was positively associated with blood glucose in both unadjusted and fully adjusted models (P<0.05 for all). Both mushroom and dietary selenium intakes were independently associated with blood glucose on multivariate analyses. In addition, high intakes of both were associated with higher diabetes prevalence in men and women (OR>1, P<0.05). CONCLUSION: The association of mushroom and selenium intakes with FBG suggests that mushroom and selenium might each independently increase the risk of diabetes. However, prospective studies are now necessary to confirm this hypothesis.

Moderate alcohol use and health: a consensus document.

AIMS: The aim of this consensus paper is to review the available evidence on the association between moderate alcohol use, health and disease and to provide a working document to the scientific and health professional communities. DATA SYNTHESIS: In healthy adults and in the elderly, spontaneous consumption of alcoholic beverages within 30 g ethanol/d for men and 15 g/d for women is to be considered acceptable and do not deserve intervention by the primary care physician or the health professional in charge. Patients with increased risk for specific diseases, for example, women with familiar history of breast cancer, or subjects with familiar history of early cardiovascular disease, or cardiovascular patients should discuss with their physician their drinking habits. No abstainer should be advised to drink for health reasons. Alcohol use must be discouraged in specific physiological or personal situations or in selected age classes (children and adolescents, pregnant and lactating women and recovering alcoholics). Moreover, the possible interactions between alcohol and acute or chronic drug use must be discussed with the primary care physician. CONCLUSIONS: The choice to consume alcohol should be based on individual considerations, taking into account the influence on health and diet, the risk of alcoholism and abuse, the effect on behaviour and other factors that may vary with age and lifestyle. Moderation in drinking and development of an associated lifestyle culture should be fostered.

Consumption of healthy foods at different content of antioxidant vitamins and phytochemicals and metabolic risk factors for cardiovascular disease in men and women of the Moli-sani study.

BACKGROUND/OBJECTIVES: To categorize healthy food groups into categories of low-antioxidant (LAC) or high-antioxidant vitamins and phytochemicals content (HAC) and comparatively associate them with metabolic risk factors for cardiovascular disease (CVD). SUBJECTS/METHODS: A total of 6879 women (55±12 years) and 6892 men (56 ± 12 years) were analyzed from the Moli-sani cohort, randomly recruited from the general population. The European Prospective Investigation into Cancer and Nutrition Food Frequency Questionnaire was used for dietary assessment. The antioxidant content of each food group was evaluated using Istituto Nazionale di Ricerca per gli Alimenti e la Nutrizione and United States Department of Agriculture (USDA) food composition tables. Healthy foods, according to a Mediterranean dietary pattern, were categorized into HAC or LAC; total food antioxidant content (FAC) score was constructed for a comparative evaluation of the consumption of these two groups. RESULTS: In men, an increase in FAC score, which represents an increased consumption of HAC with respect to LAC foods, was associated with a decrease in systolic blood pressure, diastolic blood pressure and C-reactive protein (CRP) (ß=-0.5, P=0.02, ß=-0.3, P=0.02 and ß=-0.03, P=0.03, respectively). Logistic regression analyses showed that in men 15% (30 units) increase in FAC score was associated with 6% decrease in the likelihood of having hypertension (odds ratio (OR)=0.94, 95% confidence interval (CI) 0.91-0.98) and 3% decrease in the likelihood of having a high CRP risk level (OR=0.97, 95% CI 0.94-0.99). No significant associations were observed in women. CONCLUSIONS: A possible greater protective role of healthy HAC as compared with healthy LAC foods on hypertension and inflammation was detected in men. These results stress the importance of studying healthy foods according to their content in antioxidant vitamins and phytochemicals, in primary prevention of CVD.

Tinnitus sound therapy with open ear canal hearing aids.

OBJECTIVE: The aims of this study were to evaluate the efficacy of open ear canal hearing aids in tinnitus treatment and to investigate the influence of gender, age, medication usage, tinnitus cause, tinnitus perception side, tinnitus pitch, pure tone audiometry, distortion product otoacoustic emissions, and minimal masking level on outcome. METHODOLOGY: One hundred tinnitus patients were evaluated by the tinnitus handicap inventory (THI) at the beginning of the study and after nine months of treatment. All subjects were submitted to counselling and sound enrichment from the simple sound amplification provided by the open ear canal hearing aids. RESULTS: Initial mean THI score was 54.22 (+/- 20.37) and final mean score was 28.32 (+/- 16.50), p < 0.0001. No statistically significant correlations were found between THI value reduction and the studied parameters. CONCLUSION: Open ear canal hearing aids were useful in all tinnitus patients with mild hearing loss.

Are results of tinnitus retraining therapy maintained over time? 18-month follow-up after completion of therapy.

Tinnitus retraining therapy (TRT) is a useful treatment for tinnitus. The aim of this study was to evaluate the results obtained after 18 months of TRT as well as 18 months after completion of therapy, i.e. 36 months after initiation of TRT. Forty-five subjects suffering from an idiopathic tinnitus with or without hyperacusis for at least 6 months were recruited. There were significant improvements during therapy (p < 0.001) and the mean Tinnitus Handicap Inventory (THI) was lowered by more than 20 points. These improvements persisted 18 months after treatment completion. Furthermore, the percentage of patients reporting the disappearance of their difficulties in various activities (relaxation, concentration, sleep, social relations and work) increased continuously after treatment completion. TRT improved self-perceived disability induced by chronic tinnitus for a long time after the end of therapy.
