OBJECTIVE: Information on the long-term safety of electronic cigarettes (e-cig) is still limited. We report the results after six years of follow-up of the first observational study assessing e-cig long-term effectiveness and safety. PATIENTS AND METHODS: Participants were adults who smoked ≥1 tobacco cigarette/day (tobacco smokers); or used any type of e-cig inhaling ≥50 puffs weekly (e-cig users); or used both (dual users). Participants were contacted directly or by phone and/or internet interviews. Hospital discharge abstract data and carbon monoxide level tests were also used. RESULTS: Data were available for 228 e-cig users (all ex-smokers), 469 tobacco smokers, 215 dual users. A possibly smoking-related disease (PSRD) was recorded in 90 subjects (9.9%); 11 deceased (1.2%). No differences were observed across groups in PSRD rates, with minor changes in self-reported health. Among e-cig users, 64.0% remained tobacco abstinent. Dual users and tobacco smokers did not significantly differ in the rate of cessation of tobacco (38.6% vs. 33.9%, respectively) and all products (23.7% vs. 26.4%). A comparable decrease in daily cigarettes was also observed. 39.5% of the sample switched at least once (tobacco smokers: 15.1%; dual users: 83.3%). CONCLUSIONS: After six years, no evidence of harm reduction was found among e-cig or dual users. The complete switch to e-cig might support tobacco quitters remain abstinent, but the use of e-cig in addition to tobacco did not improve smoking cessation or reduction.

OBJECTIVE: To provide an overall estimate of the direct, indirect and total costs of irritable bowel syndrome (IBS) for the adult population of the European countries with universal healthcare coverage.MATERIALS AND METHODS: We searched MedLine and Scopus databases (up to September 2018) to identify the European studies that evaluated the economic impact of IBS. Mean annual direct, indirect and total per-capita IBS costs were estimated using random-effect single-group meta-analyses of continuous data. All analyses were stratified by payer category (governments, insurance, societal), and the results were expressed as summary mean and 95% CI.RESULTS: A total of 24 studies were included in the meta-analyses. Only two studies evaluated IBS costs in Italy. The pooled summary of direct IBS per-capita cost, obtained from 23 European datasets (n=15,157), was (sic)1837/year (95% CI: 1480-2195), with large differences across payers (from (sic)1183 to (sic)3358, in countries with publicly-funded and insurance-based health systems, respectively). The mean indirect cost, extracted from 13 datasets (n=3978), was (sic)2314/year (95% CI: 1811-2817), again with wide differences across payers. Finally, the meta-analysis estimating the total annual cost, based upon 11 European datasets (n=2757), yielded a summary estimate of (sic)2889/year (95% CI: 2318-3460) per patient, ranging from (sic)1602 (insurance-based health systems) to (sic)3909 (studies adopting a societal perspective).CONCLUSIONS: Considering a conservative estimate of 2,736,700 Italian adults affected by the syndrome, the minimum costs due to IBS in Italy - likely underestimated - range from 6 to 8 billion euro per year. Given the substantial economic burden for patients, healthcare systems and society, IBS should be included among the priorities of the public health agenda.

OBJECTIVE: More than a decade after e-cigarette (e-cig) market launch, limited information are available on their safety after 24 months of use. In 2013, we started the first observational study assessing e-cig long-term effectiveness and safety, directly comparing tobacco smokers and e-cig users. Here we report the results after four years of follow-up. PATIENTS AND METHODS: Adults (30-75 years) were included if: smokers of =1 tobacco cigarette/day (tobacco smokers); users of any type of e-cig inhaling =50 puffs weekly (e-cig users); users of both tobacco and e-cig (dual users). Data were collected by phone and/or internet, and carbon monoxide levels tested in 50% of those declaring tobacco abstinence. Main outcomes were: possibly smoking-related diseases (PSRD; validated through hospital discharge data or visit in 62.6% of the sample); 4-year tobacco abstinence; number of tobacco cigarettes/day. RESULTS: Data were available for 228 e-cig users (all ex-smokers), 471 tobacco smokers, 216 dual users. A PSRD was observed in 73 subjects (8.0%). No differences emerged across groups in PSRD rates, with negligible variations in self-reported health. Of e-cig users, 63.6% remained tobacco abstinent; dual users and tobacco smokers showed non-significantly different rates of tobacco (33.8% vs. 26.8%) and all-product (20.2% vs. 19.4%) cessation, and a similar decrease in cigarettes/day. Almost 40% of the sample switched at least once (tobacco smokers: 17.2%; dual users: 81.9%). CONCLUSIONS: After four years, a scarce, non-significant harm reduction was observed among e-cig or dual users. Given the long-lasting health effects of tobacco smoking, the benefits of e-cig use may start being detectable at the next follow-up (six years). The complete switch to e-cig may help tobacco quitters remain abstinent, but e-cig use in addition to tobacco did not increase the likelihood of smoking cessation or reduction.

Previous evidence indicates that pioglitazone may improve dyslipidemia in patients with Type 2 diabetes mellitus (T2DM).The primary objective of this study was to evaluate the effect of either pioglitazone or placebo with metformin on levels of serum HDL cholesterol (HDL-C) in patients with T2DM. A secondary objective evaluated changes in metabolic syndrome (MS)-specific parameters.This multicenter, double-blind, randomized study was performed in patients with T2DM treated with metformin and hemoglobin A1c (HbA1c) levels between 6-8%, central obesity and reduced HDL-C. MS was evaluated from global changes in parameter values and expressed as a single factorial score following multivariate analysis of each parameter. 213 patients (110 in the pioglitazone group and 103 in the placebo group) were available for intention-to-treat analysis.Pioglitazone-treated patients showed a significant increase in HDL-C compared to placebo group (6.3 mg/dl vs 3.0 mg/dl; p0.01) in addition to a greater reduction in the extent of MS (-13.2 vs -4.9; p=0.0055). Upon study completion, patients treated with pioglitazone had lower levels of HbA1c (6.41±0.65 vs 6.96±0.74%; p0.001) and homeostasis model assessment-insulin resistance (HOMA-IR) (2.88±1.95 vs 4.68±3.63; p=0.013) and a reduction of the atherogenic LDL subfraction (pattern B) (-5.7%).The beneficial effects observed in pioglitazone-treated patients in the present study, (i.e. the increase in HDL-C and the reduction of insulin resistance and atherogenic LDL subfractions), support findings from the PROactive trial, where pioglitazone showed pleiotropic effects and reduced death, fatal myocardial infarction (MI) and non-fatal MI in T2DM patients with MS. Furthermore, medication used in this study showed good tolerability.

The purpose of the work described in this article was to analyze the psychometric properties of a new Italian instrument for the assessment of irritability in adult patients with epilepsy (I-Epi). Five hundred four patients from nine secondary and tertiary Italian centers for the care of epilepsy were recruited and interviewed. Each patient was evaluated on a series of demographic and clinical variables recorded before administration of the I-Epi and the AQ (Aggression Questionnaire), used for external validity. The final results supported the reliability and validity of the I-Epi as a measure of irritability in the adult epilepsy population. The psychometric characteristics of the I-Epi seemed fairly good. We believe that adoption of this new instrument could be very useful in both clinical and research management of patients with epilepsy.

Objective:\ud \ud To summarize the latest evidence on head and neck cancer epidemiology from the International Head and Neck Cancer Epidemiology (INHANCE) consortium.\ud \ud Subjects and Methods:\ud \ud INHANCE was established in 2004 to elucidate the etiology of head and neck cancer through pooled analyses of individual‐level data on a large scale. We summarize results from recent INHANCE‐based publications updating our 2015 overview.\ud \ud Results:\ud \ud Seventeen papers were published between 2015 and May 2020. These studies further define the nature of risks associated with tobacco and alcohol, and occupational exposures on head and neck cancer. The beneficial effects on incidence of head and neck cancer were identified for good oral health, endogenous and exogenous hormonal factors, and selected aspects of diet related to fruit and vegetables. INHANCE has begun to develop risk prediction models and to pool follow‐up data on their studies, finding that ~30% of cases had cancer recurrence and 9% second primary cancers, with overall‐ and disease‐specific 5‐year‐survival of 51% and 57%, respectively.\ud \ud Conclusions:\ud \ud The number and importance of INHANCE scientific findings provides further evidence of the advantages of large‐scale internationally collaborative projects and will support the development of prevention strategies.

Epub 2010 Mar 11.; International audience; The relationship between diet and oral and pharyngeal cancer has been rarely addressed considering dietary patterns. We examined this issue using data from a case-control study carried out between 1992 and 2005. Cases were 804 incident oral cancers hospitalized in 3 Italian areas. Controls were 2080 subjects hospitalized for non-neoplastic diseases. Dietary habits were investigated through a validated 78-item food-frequency questionnaire. Overall and individual measures of sampling adequacy were calculated to assess if applying a factor analysis or not. A posteriori dietary patterns were identified through a principal component factor analysis performed on a selected set of 29 nutrients. The internal reproducibility, robustness and reliability of the identified patterns were evaluated. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using unconditional multiple logistic regression models on quintiles of factor scores. The measures of sampling adequacy were generally satisfactory. We identified five major dietary patterns named Animal products, Starch-rich, Vitamins and fiber, Unsaturated fats and Retinol and niacin. The Animal products pattern was positively associated with oral cancer (OR=1.56, 95% CI: 1.13-2.15 for the highest vs. the lowest score quintile), whereas the Starch-rich pattern (OR=0.71, 95% CI: 0.50-0.99), the Vitamins and fiber pattern (OR=0.47, 95% CI: 0.34-0.65) and the Unsaturated fats pattern (OR=0.63, 95% CI: 0.45-0.86) were inversely associated with it. These findings confirm that diets rich in animal origin and animal fats are positively, and those rich in fruit and vegetables, and vegetable fats inversely related to oral and pharyngeal cancer risk.

Acknowledgements: We would like to thank WSES for the support., BACKGROUND: Severe traumatic brain-injured (TBI) patients should be primarily admitted to a hub trauma center (hospital with neurosurgical capabilities) to allow immediate delivery of appropriate care in a specialized environment. Sometimes, severe TBI patients are admitted to a spoke hospital (hospital without neurosurgical capabilities), and scarce data are available regarding the optimal management of severe isolated TBI patients who do not have immediate access to neurosurgical care. METHODS: A multidisciplinary consensus panel composed of 41 physicians selected for their established clinical and scientific expertise in the acute management of TBI patients with different specializations (anesthesia/intensive care, neurocritical care, acute care surgery, neurosurgery and neuroradiology) was established. The consensus was endorsed by the World Society of Emergency Surgery, and a modified Delphi approach was adopted. RESULTS: A total of 28 statements were proposed and discussed. Consensus was reached on 22 strong recommendations and 3 weak recommendations. In three cases, where consensus was not reached, no recommendation was provided. CONCLUSIONS: This consensus provides practical recommendations to support clinician's decision making in the management of isolated severe TBI patients in centers without neurosurgical capabilities and during transfer to a hub center.

Several studies suggest an inverse relation between coffee drinking and risk of hepatocellular carcinoma (HCC). We conducted a meta-analysis of published studies on HCC that included quantitative information on coffee consumption. Ten studies were retrieved (2,260 HCC cases), including 6 case–control studies from southern Europe and Japan (1551 cases) and 4 cohort studies from Japan (709 cases). The summary relative risk (RR) for coffee drinkers versus non-drinkers was 0.54 (95% confidence interval [CI] 0.38-0.76) for case–control studies and 0.64 (95% CI 0.56-0.74) for cohort studies. The overall RR was 0.59 (95% CI 0.49-0.72), with significant heterogeneity between studies. The overall summary RR for low or moderate coffee drinkers was 0.70 (95% CI 0.57-0.85), and that for high drinkers was 0.45 (95% CI 0.38-0.53). The summary RR for an increase of 1 cup of coffee per day was 0.77 (95% CI 0.72-0.83) from case–control studies, 0.75 (95% CI 0.65-0.85) from cohort studies, and 0.77 (95% CI 0.72-0.82) overall. The consistency of an inverse relation between coffee drinking and HCC across study design and geographic areas weighs against a major role of bias or confounding. Coffee drinking has also been related to reduced risk of other liver diseases, thus suggesting a continuum of the favorable effect of coffee on liver function. However, subjects with liver conditions may selectively reduce their coffee consumption. Conclusion: The present analysis provides evidence that the inverse relation between coffee and HCC is real, though inference on causality remains open to discussion. (HEPATOLOGY 2007.)

Aims Depression in type 2 diabetes may heavily affect the course of the disease. In this study, we investigated, among new cases with type 2 diabetes, the incidence and clinical predictors of depression and determined the extent to which depression constitutes a risk factor for acute and long-term diabetes complications and mortality. Methods In this population-based retrospective cohort study, incident cases of type 2 diabetes without a prior history of depression were identified from the administrative databases of the Emilia-Romagna Region, Italy, between 2008 and 2017 and followed up until 2020. Logistic regression models were used to identify the predictors of depression. Cox regression models were used to estimate the risk of acute complications over three years, and the risk of long-term complications and mortality over ten years. Results Incident cases with type 2 diabetes were 30,815, of whom 5146 (16.7%) developed depression. The predictors of depression onset were as follows: female sex, age > 65 years, living in rural areas and comorbid diseases. Depression in type 2 diabetes was associated with a 2.3-fold risk of developing acute complications, 1.6-fold risk of developing long-term complications and 2.8-fold mortality risk. Conclusions Our findings highlight that depression is associated with an increased risk for complications in type 2 diabetes and mortality and should not be neglected. Therefore, it is important to promote screening activities and introduce targeted and personalized treatment for depression in order to reduce the risk of poor short- and long-term outcomes of diabetes.

Background: The issue of diet and laryngeal cancer has been rarely addressed considering the potential role of dietary patterns. Methods: We examined this association using data from a case-control study carried out between 1992 and 2000. Cases were 460 histologically confirmed incident laryngeal cancers hospitalized in two Italian areas. Controls were 1,088 subjects hospitalized for acute nonneoplastic diseases unrelated to tobacco or alcohol consumption. Dietary habits were investigated through a 78-item food frequency questionnaire. A posteriori dietary patterns were identified through principal component factor analysis carried out on a selected set of 28 major nutrients. The internal reproducibility, robustness, and reliability of the identified patterns were evaluated. Odds ratios (OR) of laryngeal cancer and 95% confidence intervals (95% CI) were estimated using unconditional multiple logistic regression models on quartiles of factor scores. Results: We identified five major dietary patterns named “animal products,” “starch-rich,” “vitamins and fiber,” “vegetable unsaturated fatty acids,” and “animal unsaturated fatty acids.” The vitamins and fiber dietary pattern was inversely associated with laryngeal cancer (OR, 0.35; 95% CI, 0.24-0.52 for the highest versus the lowest score quartile), whereas the animal products (OR, 2.34; 95% CI, 1.59-3.45) and the animal unsaturated fatty acids (OR, 2.07; 95% CI, 1.42-3.01) patterns were directly associated with it. There was no significant association between the vegetable unsaturated fatty acids and the starch-rich patterns and laryngeal cancer risk. Conclusion: These findings suggest that diets rich in animal products and animal fats are directly related, and those rich in fruit and vegetables inversely related, to laryngeal cancer risk.

ObjectiveIt has been hypothesised that the use of ACE inhibitors and angiotensin receptor blockers (ARBs) might either increase or reduce the risk of severe or lethal COVID-19. The findings from the available observational studies varied, and summary estimates are urgently needed to elucidate whether these drugs should be suspended during the pandemic, or patients and physicians should be definitely reassured. This meta-analysis of adjusted observational data aimed to summarise the existing evidence on the association between these medications and severe/lethal COVID-19.MethodsWe searched MedLine, Scopus and preprint repositories up to 8 June 2020 to retrieve cohort or case–control studies comparing the risk of severe/fatal COVID-19 (either mechanical ventilation, intensive care unit admission or death), among hypertensive subjects treated with: (1) ACE inhibitors, (2) ARBs and (3) both, versus untreated subjects. Data were combined using a random-effect generic inverse variance approach.ResultsTen studies, enrolling 9890 hypertensive subjects were included in the analyses. Compared with untreated subjects, those using either ACE inhibitors or ARBs showed a similar risk of severe or lethal COVID-19 (summary OR: 0.90; 95% CI 0.65 to 1.26 for ACE inhibitors; 0.92; 95% CI 0.75 to 1.12 for ARBs). The results did not change when both drugs were considered together, when death was the outcome and excluding the studies with significant, divergent results.ConclusionThe present meta-analysis strongly supports the recommendation of several scientific societies to continue ARBs or ACE inhibitors for all patients, unless otherwise advised by their physicians who should thus be reassured.

Objective This study aimed to evaluate and quantify the relationship between coffee and gastric cancer using a uniquely large dataset from an international consortium of observational studies on gastric cancer, including data from 18 studies, for a total of 8198 cases and 21 419 controls. Methods A two-stage approach was used to obtain the pooled odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) for coffee drinkers versus never or rare drinkers. A one-stage logistic mixed-effects model with a random intercept for each study was used to estimate the dose-response relationship. Estimates were adjusted for sex, age and the main recognized risk factors for gastric cancer. Results Compared to never or rare coffee drinkers, the estimated pooled OR for coffee drinkers was 1.03 (95% CI, 0.94-1.13). When the amount of coffee intake was considered, the pooled ORs were 0.91 (95% CI, 0.81-1.03) for drinkers of 1-2 cups per day, 0.95 (95% CI, 0.82-1.10) for 3-4 cups, and 0.95 (95% CI, 0.79-1.15) for five or more cups. An OR of 1.20 (95% CI, 0.91-1.58) was found for heavy coffee drinkers (seven or more cups of caffeinated coffee per day). A positive association emerged for high coffee intake (five or more cups per day) for gastric cardia cancer only. Conclusions These findings better quantify the previously available evidence of the absence of a relevant association between coffee consumption and gastric cancer.

ObjectivesThis study aimed to identify the guiding ethical principles that should be considered for critical resource allocation during pandemic emergency situations, and especially for the COVID-19 outbreak. The secondary objective was to define the priority to be assigned to each principle.SettingThe study was conducted from March to June 2020 within the context of an ethical committee (EC) in Northern Italy.ParticipantsEleven EC members and five additional external healthcare and bioethical professionals, forming a multidisciplinary panel, took part in the study.Primary and secondary outcome measuresThe compilation of a list of ethical principles (maximum of 10 items) and their priority ranking and application within an emergency pandemic context was established as the expected outcome of this work.ResultsA consensus on 10 guiding ethical principles was reached by the multidisciplinary panel. Transparency ranked first on the priority list as the most frequently voted principle, followed by the number of lives saved, life-years saved, respect for individuals’ autonomy and equity. Other principles including life cycle, ‘sickest first’, reciprocity, instrumental value and lottery were also considered appropriate as potential tiebreakers. These principles were discussed and made consistent with the current Italian pandemic context by producing an explanatory document.ConclusionsThe identified principles could be used in preparedness plans to guide resource allocation during pandemic events. By combining their rank and relevance in relation to disease, health system organisations, social and economic settings, and critical resources at risk of scarcity, these principles could help to maximise the benefit of resource use for the community, thus reducing inequalities for individuals.

Background Alcohol and tobacco are the major risk factors for oral and pharyngeal cancer, but diet is likely to have a role, too. Objective The objective was to analyze the relationship between adherence to the 2015-2020 Dietary Guidelines for Americans (DGA), as measured by the Healthy Eating Index 2015 (HEI-2015), and oral and pharyngeal cancer risk. Moreover, this work aimed to quantify the number of avoidable cases under different scenarios of increased adherence to the DGA, with the use of the potential impact fraction. This estimates the proportion of cases that would occur if the distribution of the risk factor in the population followed an alternative distribution. Design A multicenter, case–control study was conducted in Italy between 1991 and 2009. Participants’ usual diet for the 2 years preceding study enrolment was assessed using a food frequency questionnaire. Participants and setting Cases were 946 patients admitted to major hospitals with incident, histologically confirmed oral and pharyngeal cancer. Controls were 2,492 patients admitted to the same hospitals for acute non neoplastic conditions. Main outcome measures The adherence to the DGA was assessed using the HEI-2015 score (range = 0 to 100), based on 13 components. The outcome was oral and pharyngeal cancer. Statistical analyses performed Odds ratios and the corresponding 95% CIs were estimated using multiple logistic regression models adjusted for tobacco, alcohol, and other relevant covariates. The potential impact fraction was estimated under different scenarios of adherence to the DGA. Results In this Italian population the HEI-2015 score ranged from 33.4 to 97.5. A higher HEI-2015 score was associated with a lower risk of oral and pharyngeal cancer, with an odds ratio of 0.70 (95% CI 0.62 to 0.79) for a 10-point increment of the score. The estimated potential impact fraction was 64.8% under the maximum achievable reduction scenario, and it ranged from 9% to 27% following other more feasible scenarios. Conclusions The HEI-2015 score was inversely related to oral and pharyngeal cancer risk in this Italian population. This analysis allowed for the estimation of the fraction of preventable cases, under different feasible scenarios. A share of 9% to 27% of avoidable cases of oral and pharyngeal cancer might be obtained across real-world scenarios of adherence to the DGA as measured by the HEI-2015 score.

To explore the role of coffee on health outcomes in the United States, where coffee consumption is common, we conducted a meta-analysis of prospective studies investigating the magnitude (any compared with no consumption) and the dose-response shape (cups per day) of the associations between caffeinated coffee consumption and incidence/mortality of cardiovascular disease (CVD), as well as incidence of type 2 diabetes (T2D), hepatocellular carcinoma (HCC), endometrial cancer, melanoma, and nonmelanoma skin cancer. We selected the desirable health outcomes that have been shown to be positively associated with coffee consumption. Studies were identified by searching PubMed/Embase databases up to September 2019. Inclusion criteria included prospective studies that investigated the relation of ≥3 categories of caffeinated coffee consumption and the outcomes of interest. Twenty-six studies (42 distinct cohorts), with 93,706 cases/deaths and 3,713,932 participants, met the inclusion criteria. In any coffee consumers, there was a significant inverse association with the risk of CVD (RR=0.90; 95% CI: 0.84, 0.96), T2D (RR=0.90; 95% CI: 0.85, 0.96), endometrial cancer (RR=0.85; 95% CI: 0.78, 0.92), melanoma (RR=0.89; 95% CI: 0.80, 0.99), and nonmelanoma skin cancer (RR=0.92; 95% CI: 0.89, 0.95). Coffee consumption was also inversely associated with HCC (RR=0.93; 95% CI: 0.80, 1.08), without reaching statistical significance. The dose-response relation was nonlinear uniquely for CVD (P-nonlinearity=0.01). In particular, the largest risk reduction was observed for 3-4 cups/d (∼120mL/cup) and no reduction thereafter. For other outcomes, the risk decreased linearly over the whole coffee consumption range. Current patterns of consumption in the United States would account for a fraction of avoided cases/deaths ranging from 6% to 12% according to the outcome considered. This study confirms the beneficial health effects of caffeinated coffee consumption in the US population on the health outcomes considered, and quantifies their possible magnitude.

By the end of May 2020, SARS-CoV-2 pandemic caused more than 350,000 deaths worldwide. In the first months, there have been uncertainties on almost any area: infection transmission route, virus origin and persistence in the environment, diagnostic tests, therapeutic approach, high-risk subjects, lethality, and containment policies. We provide an updated summary of the current knowledge on the pandemic, discussing the available evidence on the effectiveness of the adopted mitigation strategies.

The methods traditionally used to identify a posteriori dietary patterns are principal components, factor and cluster analysis. The aim of our study is to assess the relationship between dietary patterns derived with latent class analysis (LCA) and oral/pharyngeal cancer risk (OPC), highlighting the strengths of this method compared to traditional ones. We analyzed data from an Italian multicentric case-control study on OPC including 946 cases and 2,492 hospital controls. Dietary patterns were derived using LCA on 25 food groups. A multiple logistic regression model was used to derive odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for OPC according to the dietary patterns identified. We identified four dietary patterns. The first one was characterized by a high intake of leafy and fruiting vegetable and fruits (Prudent pattern), the second one showed a high intake of red meat and low intake of selected fruits and vegetables (Western pattern). The last two patterns showed a combination-type of diet. We labeled "Lower consumers-combination pattern" the cluster that showed a low intake of the majority of foods, and "Higher consumers-combination pattern" the one characterized by a high intake of various foods. Compared to the "Prudent pattern", the "Western" and the "Lower consumers-combination" ones were positively related to the risk of OPC (OR = 2.56, 95% CI: 1.90-3.45 and OR = 2.23, 95% CI: 1.64-3.02). No difference in risk emerged for the "Higher consumers-combination pattern" (OR = 1.28, 95% CI: 0.92-1.77).

AimsThis retrospective case-control study was aimed at identifying potential independent predictors of severe/lethal COVID-19, including the treatment with Angiotensin-Converting Enzyme inhibitors (ACEi) and/or Angiotensin II Receptor Blockers (ARBs).Methods and resultsAll adults with SARS-CoV-2 infection in two Italian provinces were followed for a median of 24 days. ARBs and/or ACEi treatments, and hypertension, diabetes, cancer, COPD, renal and major cardiovascular diseases (CVD) were extracted from clinical charts and electronic health records, up to two years before infection. The sample consisted of 1603 subjects (mean age 58.0y; 47.3% males): 454 (28.3%) had severe symptoms, 192 (12.0%) very severe or lethal disease (154 deaths; mean age 79.3 years; 70.8% hypertensive, 42.2% with CVD). The youngest deceased person aged 44 years. Among hypertensive subjects (n = 543), the proportion of those treated with ARBs or ACEi were 88.4%, 78.7% and 80.6% among patients with mild, severe and very severe/lethal disease, respectively. At multivariate analysis, no association was observed between therapy and disease severity (Adjusted OR for very severe/lethal COVID-19: 0.87; 95% CI: 0.50-1.49). Significant predictors of severe disease were older age (with AORs largely increasing after 70 years of age), male gender (AOR: 1.76; 1.40-2.23), diabetes (AOR: 1.52; 1.05-2.18), CVD (AOR: 1.88; 1.32-2.70) and COPD (AOR: 1.88; 1.11-3.20). Only gender, age and diabetes also predicted very severe/lethal disease.ConclusionNo association was found between COVID-19 severity and treatment with ARBs and/or ACEi, supporting the recommendation to continue medication for all patients unless otherwise advised by their physicians.

Diabetes increases endometrial cancer risk. We investigated the role of a diabetes risk reduction diet (DRRD) on the risk of endometrial cancer using data from a multicentric, Italian hospital-based case–control study (1992–2006) enrolling 454 histologically confirmed cases of endometrial cancer and 908 controls matched by age and center. We derived a DRRD score assigning higher scores for higher intakes of cereal fiber, fruit, coffee, polyunsaturated:saturated fatty acid ratio, and nuts and for lower glycemic load and lower intakes of red/processed meat and sugar-sweetened beverages/fruit juices. The odds ratios (OR) of endometrial cancer according to the DRRD score were derived by multiple conditional logistic regression models. The OR for high (DRRD score &gt, 24, i.e., third tertile) versus medium–low adherence to the DRRD was 0.73 (95% confidence interval, CI, 0.55–0.97). Similar results were observed after the exclusion of diabetic women (OR 0.75, 95% CI, 0.56–1.00) and allowance for total vegetable consumption (OR 0.80, 95% CI, 0.60–1.07). Inverse associations were observed in most of the analyzed subgroups. The OR for high DRRD combined with high vegetable consumption was 0.45 (95% CI, 0.28–0.73). Our results suggest that diets able to reduce diabetes risk may also reduce endometrial cancer risk. High vegetable consumption combined with high adherence to the DRRD may provide additional benefit in endometrial cancer prevention.

Background & aimsHepatitis C (HCV) is associated with several extrahepatic manifestations, and estimates of the hospitalization burden related to these comorbidities are still limited. The aim of this study is to quantify the hospitalization risk associated with comorbidities in an Italian cohort of HCV-infected patients and to assess which of these comorbidities are associated with high hospitalization resource utilization.MethodsIndividuals aged 18 years and older with HCV-infection were identified in the Abruzzo's and Campania's hospital discharge abstracts during 2011-2014 with 1-year follow-up. Cardio-and cerebrovascular disease, diabetes and renal disease were grouped as HCV-related comorbidities. Negative binomial models were used to compare the hospitalization risk in patients with and without each comorbidity. Logistic regression model was used to identify the characteristics of being in the top 20% of patients with the highest hospitalization costs (high-cost patients).Results15,985 patients were included; 19.9% had a liver complication and 48.6% had one or more HCV-related comorbidities. During follow-up, 36.0% of patients underwent at least one hospitalization. Liver complications and the presence of two or more HCV-related comorbidities were the major predictors of hospitalization and highest inpatient costs. Among those, patients with cardiovascular disease had the highest risk of hospitalization (Incidence Rate Ratios = 1.42;95%CI:1.33-1.51) and the highest likelihood of becoming high-cost patients (Odd Ratio = 1.37;95%CI:1.20-1.57).ConclusionBeyond advanced liver disease, HCV-related comorbidities (especially cardiovascular disease) are the strongest predictors of high hospitalization rates and costs. Our findings highlight the potential benefit that early identification and treatment of HCV might have on the reduction of hospitalization costs driven by extrahepatic conditions.

Diets rich in vegetables and fruit have been associated with reduced risk of gastric cancer, and there is suggestive evidence that citrus fruits have a protective role. Our study aimed at evaluating and quantifying the association between citrus fruit intake and gastric cancer risk. We conducted a one-stage pooled analysis including 6,340 cases and 14,490 controls from 15 case–control studies from the stomach cancer pooling (StoP) project consortium. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) of gastric cancer across study-specific tertiles of citrus fruit intake (grams/week) were estimated by generalized linear mixed effect models, with logistic link function and random intercept for each study. The models were adjusted for sex, age, and the main recognized risk factors for gastric cancer. Compared to the first third of the distribution, the adjusted pooled OR (95% CI) for the highest third was 0.80 (0.73–0.87). The favourable effect of citrus fruits increased progressively until three servings/week and leveled off thereafter. The magnitude of the association was similar between cancer sub-sites and histotypes. The analysis by geographic area showed no association in studies from the Americas. Our data confirm an inverse association between citrus fruits and gastric cancer and provide precise estimates of the magnitude of the association. However, the null association found in studies from America and in some previous cohort studies prevent to draw definite conclusions on a protective effect of citrus fruit consumption. © 2018 UICC

Background: Pancreatic cancer is a leading cause of cancer death. A role of dietary factors in pancreatic carcinogenesis has been suggested. The World Cancer Research Fund (WCRF) and the American Institute for Cancer Research (AICR) published 8 recommendations for cancer prevention. We evaluated the effect of adherence to the WCRF/AICR recommendations on pancreatic cancer risk. Methods: We operationalized 7 of the 8 WCRF/AICR recommendations to generate a WCRF/AICR score. We examined the association of WCRF/AICR score with pancreatic cancer in data from an Italian case-control study of 326 incident cases and 652 controls. Results: Adherence to WCRF/AICR recommendations was associated with a significantly decreased risk of pancreatic cancer. Using a WCRF/AICR score

Purpose: Few studies investigated the role of diet on nasopharyngeal cancer (NPC) risk in non-endemic areas. The aim of this study was to assess the association between adherence to the traditional Mediterranean diet and NPC risk in a southern European low-risk population. Methods: We conducted a hospital-based case-control study in Italy, including 198 histologically confirmed NPC cases and 594 matched controls. Dietary habits were collected by means of a validated food-frequency questionnaire, including 83 foods, food groups, or beverages. Adherence to the traditional Mediterranean diet was assessed through a Mediterranean Diet Score (MDS), based on nine dietary components characterizing this dietary profile, i.e., high intake of vegetables, fruits and nuts, cereals, legumes, and fish; low intake of dairy products and meat; high monounsaturated to saturated fatty acid ratio; and moderate alcohol intake. We estimated odds ratios (ORs) of NPC, and the corresponding 95% confidence intervals (CIs), for increasing MDS (i.e., increasing adherence) using multiple logistic regression models, adjusted for major confounding factors. Results: As compared to MDS ≤ 4, the ORs of NPC were 0.83 (95% CI: 0.54–1.25) for MDS of 5 and 0.66 (95% CI: 0.44–0.99) for MDS ≥ 6, with a significant trend of decreasing risk (p 0.043). The corresponding population attributable fraction was 22%, indicating that 22% of NPC cases in this population would be avoided by shifting all subjects to a score ≥6. Conclusions: Our study supports a favorable role of the Mediterranean diet on NPC risk.

International audience; Hospital networks are an emerging organizational form designed to face the new challenges of public health systems. Although the benefits introduced by network models in terms of rationalization of resources are known, evidence about stakeholders’ perspectives on hospital network performance from the literature is scanty. Using the Competing Values Framework of organizational effectiveness and its subsequent adaptation by Minvielle et al., we conducted in 2009 a survey in five hospitals of an Italian network for oncological care to examine and compare the views on hospital network performance of internal stakeholders (physicians, nurses and the administrative staff). 329 questionnaires exploring stakeholders’ perspectives were completed, with a response rate of 65.8%. Using exploratory factor analysis of the 66 items of the questionnaire, we identified 4 factors, i.e. Centrality of relationships, Quality of care, Attractiveness/Reputation and Staff empowerment and Protection of workers’ rights. 42 items were retained in the analysis. Factor scores proved to be high (mean score > 8 on a 10-item scale), except for Attractiveness/Reputation (mean score 6.79), indicating that stakeholders attach a higher importance to relational and health care aspects. Comparison of factor scores among stakeholders did not reveal significant differences, suggesting a broadly shared view on hospital network performance.

Udgivelsesdato: 2008-Nov BACKGROUND: Studies on pet ownership as a risk or protective factor for asthma and allergy show inconsistent results. This may be on account of insufficient adjustment of confounding factors. AIM: The objective of this study was to describe determinants of cat and dog ownership in European families with and without allergies. METHODS: Within the EU-funded network of excellence GA(2)LEN, we performed meta-analyses with data from 12 ongoing European birth cohort studies on asthma and allergy. Each of the birth cohort studies enrolled between 485 and 4089 children. Pet ownership, allergic status (asthma, allergic rhinitis, eczema) of parents and siblings, parental education, access to ground floor, and number of people living at home were assessed by questionnaires. RESULTS: Among the 25 056 families from seven European countries cats (14.9%) were more common than dogs (12.0%). Allergic family history significantly reduced the odds to own a cat (adjusted combined random-effect OR 0.91; 95% CI 0.85-0.99), or dog (0.90; 0.86-0.94). A higher parental educational level had even more pronounced effects on cat (0.84; 0.71-0.98), and dog ownership (0.61; 0.54-0.70). Elder siblings reduced the odds to own cats, but not dogs. Convenient ground access significantly increased the odds, whereas crowding at home was not associated with cat or dog ownership. CONCLUSIONS: The chances to own a cat or dog were significantly reduced in allergic families, in parents with a higher educational level, and in homes without convenient ground access. In addition to parental allergies, social and housing factors should be considered as potential confounders in studies on pet exposure and allergic diseases.

Background: The issue of diet and laryngeal cancer has been rarely addressed considering the potential role of dietary patterns. Methods: We examined this association using data from a case-control study carried out between 1992 and 2000. Cases were 460 histologically confirmed incident laryngeal cancers hospitalized in two Italian areas. Controls were 1,088 subjects hospitalized for acute nonneoplastic diseases unrelated to tobacco or alcohol consumption. Dietary habits were investigated through a 78-item food frequency questionnaire. A posteriori dietary patterns were identified through principal component factor analysis carried out on a selected set of 28 major nutrients. The internal reproducibility, robustness, and reliability of the identified patterns were evaluated. Odds ratios (OR) of laryngeal cancer and 95% confidence intervals (95% CI) were estimated using unconditional multiple logistic regression models on quartiles of factor scores. Results: We identified five major dietary patterns named “animal products, ”“ starch-rich, ”“ vitamins and fiber, ”“ vegetable unsaturated fatty acids,” and “animal unsaturated fatty acids.” The vitamins and fiber dietary pattern was inversely associated with laryngeal cancer (OR, 0.35; 95% CI, 0.24-0.52 for the highest versus the lowest score quartile), whereas the animal products (OR, 2.34; 95% CI, 1.59-3.45) and the animal unsaturated fatty acids (OR, 2.07; 95% CI, 1.42-3.01) patterns were directly associated with it. There was no significant association between the vegetable unsaturated fatty acids and the starch-rich patterns and laryngeal cancer risk. Conclusion: These findings suggest that diets rich in animal products and animal fats are directly related, and those rich in fruit and vegetables inversely related, to laryngeal cancer risk.

Background: Inconclusive information is available on the potential role of milk and dairy products on the risk of cancer at several sites. Methods: We analyzed data from a large and integrated network of hospital-based case-control studies in Italy on cancers of the oral cavity and pharynx (598 cases, 1491 controls), oesophagus (304 cases, 743 controls), colorectum (1953 cases, 4154 controls), larynx (460 cases, 1088 controls), breast (2569 cases, 2588 controls), ovary (1031 cases, 2411 controls) and prostate (1294 cases, 1451 controls). Results: Multivariate odds ratio (OR) for the highest consumption level of any type of milk was 0.94 (95% confidence interval, CI: 0.61-1.33) for cancers of the oral cavity and pharynx, 1.20 (95% CI: 0.76-1.90) for oesophageal, 0.77 (95% CI: 0.62-0.96) for colon, 0.80 (95% CI: 0.60-1.05) for rectal, 0.83 (95% CI: 0.56-1.21) for laryngeal, 0.91 (95% CI: 0.76-1.10) for breast, 0.89 (95% CI: 0.68-1.15) for ovarian and 1.08 (95% CI: 0.84-1.37) for prostate cancer. A significant trend in risk was found for colon cancer only. Inverse associations were observed between consumption of skim milk and cancers of colon (OR=0.84; 95% CI: 0.73-0.97), rectum (OR=0.76; 95% CI: 0.64-0.91), breast (OR=0.87; 95% CI: 0.77-0.98) and ovary (OR=0.77; 95% CI: 0.66-0.91). Conversely, whole milk consumption was directly associated with cancer of the rectum (OR=1.22; 95% CI: 1.03-1.44) and ovary (OR=1.25; 95% CI: 1.07-1.46). High consumption of cheese was inversely related to colon cancer risk (OR=0.80; 95% CI: 0.67-0.95). Conclusions: There was a modest direct association between milk and dairy products and prostate cancer, and a moderate inverse one for colorectal cancer. However, our findings indicate that milk and dairy products are not strong risk indicators for any of the cancers considered.

Objective Since conflicting results have been published on the role of tobacco smoking on the risk of endometriosis, we provide an up-to-date summary quantification of this potential association. Design We performed a PubMed/MEDLINE search of the relevant publications up to September 2014, considering studies on humans published in English. We searched the reference list of the identified papers to find other relevant publications. Case–control as well as cohort studies have been included reporting risk estimates on the association between tobacco smoking and endometriosis. 38 of the 1758 screened papers met the inclusion criteria. The selected studies included a total of 13 129 women diagnosed with endometriosis. Setting Academic hospitals. Main outcome measure Risk of endometriosis in tobacco smokers. Results We obtained the summary estimates of the relative risk (RR) using the random effect model, and assessed the heterogeneity among studies using the χ 2 test and quantified it using the I 2 statistic. As compared to never-smokers, the summary RR were 0.96 (95% CI 0.86 to 1.08) for ever smokers, 0.95 (95% CI 0.81 to 1.11) for former smokers, 0.92 (95% CI 0.82 to 1.04) for current smokers, 0.87 (95% CI 0.70 to 1.07) for moderate smokers and 0.93 (95% CI 0.69 to 1.26) for heavy smokers. Conclusions The present meta-analysis provided no evidence for an association between tobacco smoking and the risk of endometriosis. The results were consistent considering ever, former, current, moderate and heavy smokers, and across type of endometriosis and study design.

BACKGROUND: Besides tobacco and alcohol, dietary habits may have a relevant role in oral cavity and pharyngeal (OCP) cancer. METHODS: We analysed the role of selected food groups and nutrients on OCP cancer in a case-control study carried out between 1997 and 2009 in Italy and Switzerland. This included 768 incident, histologically confirmed squamous cell carcinoma cases and 2078 hospital controls. Odds ratios (ORs) were estimated using logistic regression models including terms for tobacco, alcohol and other relevant covariates. RESULTS: Significant inverse trends in risk were observed for all vegetables (OR=0.19, for the highest vs the lowest consumption) and all fruits (OR=0.39), whereas significant direct associations were found for milk and dairy products (OR=1.50), eggs (OR=1.71), red meat (OR=1.55), potatoes (OR=1.85) and desserts (OR=1.68), although trends in risk were significant only for potatoes and desserts. With reference to nutrients, significant inverse relations were observed for vegetable protein (OR=0.45, for the highest vs the lowest quintile), vegetable fat (OR=0.54), polyunsaturated fatty acids (OR=0.53), α-carotene (OR=0.51), β-carotene (OR=0.28), β-cryptoxanthin (OR=0.37), lutein and zeazanthin (OR=0.34), vitamin E (OR=0.26), vitamin C (OR=0.40) and total folate (OR=0.34), whereas direct ones were observed for animal protein (OR=1.57), animal fat (OR=2.47), saturated fatty acids (OR=2.18), cholesterol (OR=2.29) and retinol (OR=1.88). Combinations of low consumption of fruits and vegetables, and high consumption of meat with high tobacco and alcohol, led to 10- to over 20-fold excess risk of OCP cancer. CONCLUSION: Our study confirms and further quantifies that a diet rich in fruits and vegetables and poor in meat and products of animal origin has a favourable role against OCP cancer.

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.

Turati, Federica Edefonti, Valeria Talamini, Renato Ferraroni, Monica Malvezzi, Matteo Bravi, Francesca Franceschi, Silvia Montella, Maurizio Polesel, Jerry Zucchetto, Antonella La Vecchia, Carlo Negri, Eva Decarli, Adriano eng Comparative Study Meta-Analysis Research Support, Non-U.S. Gov't Baltimore, Md. 2011/11/19 06:00 Hepatology. 2012 May;55(5):1416-25. doi: 10.1002/hep.24794. Epub 2012 Mar 21.; International audience; Familial clustering of hepatocellular carcinoma (HCC) has been frequently reported in eastern Asiatic countries, where hepatitis B infection is common. Little is known about the relationship between family history of liver cancer and HCC in Western populations. We carried out a case-control study in Italy, involving 229 HCC cases and 431 hospital controls. Data on family history were summarized through a binary indicator (yes/no) and a family history score (FHscore), considering selected family characteristics. Odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) were obtained from unconditional multiple logistic regression models, including terms for age, sex, study center, education, tobacco smoking, alcohol drinking, hepatitis B surface antigen, and/or anti-hepatitis C virus positivity. We also performed a meta-analysis on family history of liver cancer and liver cancer updated to April 2011 using random-effects models. After adjustment for chronic infection with hepatitis B/C viruses, family history of liver cancer was associated with HCC risk, when using both the binary indicator (OR, 2.38; 95% CI, 1.01-5.58) and the FHscore, with increasing ORs for successive score categories. Compared to subjects without family history and no chronic infection with hepatitis B/C viruses, the OR for those exposed to both risk factors was 72.48 (95% CI, 21.92-239.73). In the meta-analysis, based on nine case-control and four cohort studies, for a total of approximately 3,600 liver cancer cases, the pooled relative risk for family history of liver cancer was 2.50 (95% CI, 2.06-3.03). CONCLUSION: A family history of liver cancer increases HCC risk, independently of hepatitis. The combination of family history of liver cancer and hepatitis B/C serum markers is associated with an over 70-fold elevated HCC risk.

Epub 2011 Nov 28.; International audience; BACKGROUND: The association between dietary patterns and head and neck cancer has rarely been addressed. PATIENTS AND METHODS: We used individual-level pooled data from five case-control studies (2452 cases and 5013 controls) participating in the International Head and Neck Cancer Epidemiology consortium. A posteriori dietary patterns were identified through a principal component factor analysis carried out on 24 nutrients derived from study-specific food-frequency questionnaires. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using unconditional logistic regression models on quintiles of factor scores. RESULTS: We identified three major dietary patterns named 'animal products and cereals', 'antioxidant vitamins and fiber', and 'fats'. The 'antioxidant vitamins and fiber' pattern was inversely related to oral and pharyngeal cancer (OR=0.57, 95% CI 0.43-0.76 for the highest versus the lowest score quintile). The 'animal products and cereals' pattern was positively associated with laryngeal cancer (OR=1.54, 95% CI 1.12-2.11), whereas the 'fats' pattern was inversely associated with oral and pharyngeal cancer (OR=0.78, 95% CI 0.63-0.97) and positively associated with laryngeal cancer (OR=1.69, 95% CI 1.22-2.34). CONCLUSIONS: These findings suggest that diets rich in animal products, cereals, and fats are positively related to laryngeal cancer, and those rich in fruit and vegetables inversely related to oral and pharyngeal cancer.

"Chronic pain is a common problem in clinical practice and women are affected more often than men. Morphine is often used for long-term pain relief, but it induces side effects including endocrine alterations. The aim of the present study was to assess the behavioural and hormonal effects of transdermal buprenorphine in women suffering from persistent non-malignant pain. Hormones (LH, FSH, total and free testosterone, estradiol, cortisol) and pain measures (visual analogue scale, McGill Pain questionnaire, present pain intensity test) were evaluated at baseline and after 1, 3 and 6 months. Subjects were recruited in the Second University of Naples Pain Research Centre. Eighteen chronic pain women were included in the study, divided into pre- and post-menopausal groups. A transdermal buprenorphine patch (Buprenorphine TDS, 35 µg\/h) was administered every 72 h. As expected, buprenorphine administration led to a decrease in pain intensity and no side effects suggestive of hypogonadism were recorded. Pain measures decreased at the first control visit (T1) in both groups. Total and free testosterone were not reduced by treatment (they tended to increase in both groups) while cortisol progressively recovered from the quite low levels detected at the beginning of treatment. These data confirm that buprenorphine is a safe and effective drug for pain relief in women. It is free from the adverse effects on gonadal hormones frequently associated with other opioid treatments. The lack of opioid-induced effects on gonadal hormones (i.e. hypogonadism) is important to guarantee safe long-term pain treatment.. . "

Objective: Several studies have shown an inverse relation between vegetable and fruit intake and pancreatic cancer, but no specific beneficial component of such foods has been consistently identified. We considered the role of 15 selected vitamins and carotenoids and 6 minerals on pancreatic cancer risk in an Italian case–control study. Methods: Subjects were 326 patients with incident pancreatic cancer and 652 controls, admitted to the same hospitals as cases for acute conditions. Micronutrient computation was based on a validated and reproducible food-frequency questionnaire. We estimated the odds ratios (OR) and confidence intervals (CI) using conditional logistic regression models, adjusted for various confounding factors and for energy intake, according to the residual model. Results: Comparing the highest to the lowest quintile of intake, the OR were 0.60 (95% CI 0.36–0.98) for vitamin E, 0.44 (95% CI 0.27–0.73) for vitamin C, 0.56 (95% CI 0.34–0.93) for folate, and 0.57 (95% CI 0.35–0.92) for potassium. No significant inverse associations were observed for α-carotene (OR = 0.69, 95% CI 0.43–1.12), β-carotene (OR = 0.64, 95% CI 0.39–1.06), and β-cryptoxanthin (OR = 0.66, 95% CI 0.39–1.09). No relation was found for other micronutrients considered. Conclusion: Our findings support a favorable role of vitamins E and C, selected carotenoids, and folate on pancreatic carcinogenesis.

OBJECTIVE: The role of diet on colorectal cancer has been considered in terms of single foods and nutrients, but less frequently in terms of dietary patterns. METHODS: Data were derived from an Italian case-control study, including 1,225 subjects with cancer of the colon, 728 subjects with rectal cancer, and 4,154 hospital controls. We identified dietary patterns on a selected set of nutrients through principal component factor analysis. Odds ratios (OR) and 95% confidence intervals for both cancers were estimated using unconditional multiple logistic regression. RESULTS: We identified 5 major dietary patterns. Direct associations were observed between the Starch-rich pattern and both cancer of the colon (OR = 1.68) and of the rectum (OR = 1.74). Inverse relationships were found between the Vitamins and fiber pattern and rectal cancer (OR = 0.61), between the Unsaturated fats (animal source) and the Unsaturated fats (vegetable source) and cancer of the colon (OR = 0.80 and OR = 0.79, respectively). No other significant association was found. CONCLUSIONS: The Starch-rich pattern is potentially an unfavorable indicator of risk for both colon and rectal cancer, whereas the Vitamins and fiber pattern is associated with a reduced risk of rectal cancer and the Unsaturated fats patterns with a reduced risk of colon cancer.

BACKGROUND: Falls are the main cause of accidental death in persons aged 65 years or older. METHODS: Using MEDLINE and previous reviews, we searched for prospective studies investigating risk factors for falls among community-dwelling older people. For risk factors investigated by at least 5 studies in a comparable way, we computed pooled odds ratios (ORs) using random-effects models, with a test for heterogeneity. RESULTS: A total of 74 studies met the inclusion criteria and 31 risk factors were considered, including sociodemographic, mobility, sensory, psychologic, and medical factors and medication use. The strongest associations were found for history of falls (OR = 2.8 for all fallers; OR = 3.5 for recurrent fallers), gait problems (OR = 2.1; 2.2), walking aids use (OR = 2.2; 3.1), vertigo (OR = 1.8; 2.3), Parkinson disease (OR = 2.7; 2.8), and antiepileptic drug use (OR = 1.9; 2.7). For most other factors, the ORs were moderately above 1. ORs were generally higher for recurrent fallers than for all fallers. For some factors, there was substantial heterogeneity among studies. For some important factors (eg, balance and muscle weakness), we did not compute a summary estimate because the measures used in various studies were not comparable. CONCLUSIONS: This meta-analysis provides comprehensive evidence-based assessment of risk factors for falls in older people, confirming their multifactorial etiology. Some nonspecific indicators of high baseline risk were also strong predictors of the risk of falling.

Background: There have been several studies on diet and gastric cancer, but only a few investigations have considered the role of dietary patterns. Methods: We investigated gastric cancer risk in relation to dietary patterns in a case-control study conducted in northern Italy between 1997 and 2007, including 230 patients with incident, histologically confirmed gastric cancer and 547 frequency-matched controls, admitted to the same hospitals as cases, with acute nonneoplastic conditions. Dietary habits were investigated through a validated food frequency questionnaire including 78 foods and beverages. We identified a posteriori dietary patterns on a selected set of 28 micro- and macro-nutrients through an exploratory principal component factor analysis. We estimated the odds ratios (OR) and the corresponding 95% confidence intervals (95% CI) using conditional logistic regression models on quartiles of factor scores. Results: We identified four major dietary patterns, named “animal products”, “vitamins and fiber”, “vegetable unsaturated fatty acids”, and “starch-rich”. We observed a positive association between gastric cancer risk and the “animal products” (OR, 2.13; 95% CI, 1.34-3.40, for the highest versus the lowest score quartile) and the “starch-rich” (OR, 1.67; 95% CI, 1.01-2.77) dietary patterns. The “vitamins and fiber” pattern (OR, 0.60; 95% CI, 0.37-0.99) was inversely associated with gastric cancer, whereas no significant association emerged with the “vegetable unsaturated fatty acids” pattern (OR, 0.89; 95% CI, 0.56-1.42). Conclusions: Our analysis suggests a protective effect against gastric cancer risk of dietary patterns rich in fruits and vegetables, and a positive association of dietary patterns rich in meats and animal fats and starchy foods.

Objective: Fiber intake has been inversely related to stomach cancer risk, although this issue is still controversial. Methods: A case-control study was conducted in Italy between 1997 and 2007, including 230 cases with incident, histologically confirmed stomach cancer, and 547 controls with acute, non-neoplastic diseases. Dietary habits were investigated through a validated food frequency questionnaire. Results: Compared with the lowest quintile of intake, the multivariate odds ratios (ORs, including terms for major recognised confounding factors and total energy intake) for the highest quintile were 0.47 (95% confidence interval (CI): 0.28-0.79) for total fiber, 0.50 (95% CI: 0.30-0.85) for soluble non-cellulose polysaccharides (NCP), 0.39 (95% CI: 0.23-0.66) for total insoluble fiber, 0.54 (95% CI: 0.32-0.91) for insoluble NCP, 0.37 (95% CI: 0.22-0.64) for cellulose, and 0.59 (95% CI: 0.36-0.98) for lignin. With reference to the sources of fiber, an inverse association was found for fiber from vegetable (OR = 0.42, 95% CI: 0.24-0.72), and to a lesser extent from fruit (OR = 0.65, 95% CI: 0.38-1.10), but not for fiber from grain (OR = 1.25, 95% CI: 0.77-2.03). Conclusions: This study found an inverse relationship between stomach cancer risk and various types of fiber, derived, in particular, from vegetables and fruit.

Objective Although several studies have been conducted on the relation between dietary habits and endometrial cancer risk, the evidence for specific food groups is still controversial. Study Design We analyzed data from an Italian case-control study including 454 women with histologically confirmed endometrial cancer and 908 controls admitted to the same hospitals for acute, nonneoplastic conditions. Multivariate odds ratios (ORs) were obtained after allowance for major potential confounding factors. Results A significant increase in risk was observed for red meat, with an OR of 2.07 for an increment of 1 serving per day. Inverse associations were observed for coffee (OR, 0.83), cereals (OR, 0.92), and vegetables (OR, 0.83). Conclusion Our results support the existence of a relation between dietary habits and endometrial cancer risk and in particular suggest that a diet rich in red meat and poor in vegetables may have an unfavorable effect.

We conducted a metaanalysis of published studies on the relation between coffee drinking and endometrial cancer risk, which included 2 cohort (201 cases) and 7 case-control studies (2409 cases). The summary relative risk (RR) for coffee drinkers vs nondrinkers was 0.80 (95% confidence interval [CI], 0.68-0.94), with significant heterogeneity between studies. Compared with nondrinkers, the summary RR was 0.87 (95% CI, 0.78-0.97) for low-to-moderate coffee drinkers and 0.64 (95% CI, 0.48-0.86) for heavy coffee drinkers. The summary RR for an increase of 1 cup/d was 0.93 (95% CI, 0.89-0.97), which suggests an inverse relation between coffee and endometrial cancer. However, the causality must be confirmed.

Although nutrition and diet have been related to renal cell carcinoma (RCC), the role of specific foods or nutrients on this cancer is still controversial. We evaluated the relation between a wide range of foods and the risk of RCC in an Italian case-control study including 767 patients (494 men and 273 women) younger than 79 Years with incident, histologically confirmed RCC, and 1,534 controls (988 men and 546 women) admitted to the same hospitals as cases for a wide spectrum of acute, non-neoplastic conditions, not related to long term diet modifications. A validated and reproducible food frequency questionnaire, including 78 foods and beverages, plus a separate section on alcohol drinking, was used to assess patients' dietary habits 2 years before diagnosis or hospital admission. Multivariate odds ratios (OR) were obtained after allowance for energy intake and other major confounding factors. A significant direct trend in risk was found for bread (OR = 1.94 for the highest versus the lowest intake quintile), and a modest excess of risk was observed for pasta and rice (OR = 1.29), and milk and yoghurt (OR = 1.27). Poultry (OR = 0.74), processed meat (OR = 0.64) and vegetables (OR = 0.65) were inversely associated with RCC risk. No relation was found for coffee and tea, soups, eggs, red meat, fish, cheese, pulses, potatoes, fruits, desserts and sugars. The results of this study provide further indications on dietary correlates of RCC, and in particular indicate that a diet rich in refined cereals and poor in vegetables may have an unfavorable role on RCC.

Background Although prostate cancer is one of the most common male cancers, its aetiology—and particularly the role of comorbidity—remains poorly understood. Patients and methods Between 1991 and 2002, a case–control study on prostate cancer was conducted in Italy. This included 1294 men under the age of 75 years with incident, histologically confirmed prostate cancer, and 1451 controls, admitted to the same hospitals as cases for a wide spectrum of acute, non-neoplastic diseases. The subjects' self-reported history of selected medical conditions was assessed through a structured and satisfactorily reproducible questionnaire. Multivariate odds ratios (ORs) and 95% confidence intervals (CIs) were obtained after allowance for major potential confounding factors. Results A significant direct relation was observed between hypercholesterolaemia and prostate cancer (OR = 1.51, 95% CI 1.23–1.85). This association was stronger (OR = 1.80) in older subjects (age ≥65) than in younger ones (OR = 1.32). A non-significant excess risk of prostate cancer was also observed for gallstones (OR = 1.26, 95% CI 0.93–1.70) and the relation was apparently stronger in patients with lower body mass index (OR = 1.59). Conclusions This study suggests a possible relation between hypercholesterolaemia and prostate cancer.

Objective: As intake of flavonoids has been associated with reduced risk of coronary heart disease but data on the relation with specific classes of flavonoids are scarce, we assessed the relation between dietary intake of specific classes of flavonoids and the risk of acute myocardial infarction (AMI) in an Italian population. Design: Case-control study. Dietary information was collected by interviewers on a questionnaire tested for validity and reproducibility. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were obtained by multiple logistic regression models including terms for energy and alcohol intake, as well as sociodemographic factors, tobacco and other major recognised risk factors for AMI. Setting: Milan, Italy, between 1995 and 2003. Subjects: Cases were 760 patients, below age 79 years, with a first episode of non-fatal AMI, and controls were 682 patients admitted to hospital for acute conditions unrelated to diet. Results: A reduced risk of AMI was found for increasing intake of anthocyanidins (OR=0.45, 95% CI 0.26-0.78 for the highest vs. the lowest quintile, P-trend=0.003) and flavonols (OR=0.65, 95% CI 0.41-1.02, P-trend=0.02). A tendency towards reduced risks, although not significant, was observed for flavan-3-ols (OR=0.73, 95% CI 0.48-1.10) and total flavonoids (OR=0.74, 95% CI 0.49-1.14). No meaningful heterogeneity was found between the sexes. No association emerged for other flavonoids, including isoflavones, flavanones and flavones. Conclusions: High intake of anthocyanidins reduced the risk of AMI even after allowance for alcohol, fruit and vegetables, supporting a real inverse association between this class of flavonoids and AMI risk.

Objectives. To evaluate the role of a wide range of foods on the risk of benign prostatic hyperplasia (BPH), we conducted a case-control study in Italy between 1991 and 2002. Although BPH is an extremely common condition, particularly among older men, its risk factors, including dietary ones, remain largely undefined. Methods. Included in the study were 1369 patients younger than 75 years old surgically treated for BPH and 1451 controls younger than 75 years of age who had been admitted to the same hospitals as cases for a wide spectrum of acute, non-neoplastic conditions. A validated and reproducible food frequency questionnaire, including 78 foods and beverages, plus a separate section on alcoholic beverages, was used to assess patients' dietary habits 2 years before diagnosis or hospital admission. Multivariate odds ratios (OR) were obtained after allowance for energy intake and other major potential confounding factors. Results. A significant trend of increasing risk with more frequent consumption was found for cereals (OR 1.55 for the greatest versus lowest quintile), bread (OR 1.69), eggs (OR 1.43), and poultry (OR 1.39). Inverse associations were observed for soups (OR 0.74), pulses (OR 0.74), cooked vegetables (OR 0.66), and citrus fruit (OR 0.82). No association was observed for milk and yogurt products, coffee and tea, pasta and rice, fish, cheese, row vegetables, potatoes, fruit, or desserts. Conclusions. The results of this study suggest a role for dietary habits on the risk of BPH. In particular, a diet rich in cereals and some types of meat and poor in vegetables and pulses may have an unfavorable effect in this Italian population. UROLOGY 67: 73-79, 2006.

Objectives To better understand the role of specific macronutrients on the risk of benign prostatic hyperplasia (BPH), we used data from an Italian case-control study. Although BPH is extremely common among the elderly, its etiology—and, particularly, the role of diet and specific macronutrients—is still unclear. Methods A case-control study of 1369 patients with BPH and 1451 controls, admitted to the same hospitals for a wide spectrum of acute, non-neoplastic conditions, was conducted in Italy. The subjects' usual diet was investigated through a validated and reproducible food frequency questionnaire. Multivariate odds ratios (ORs) and 95% confidence intervals (CIs) were obtained after allowance for energy intake and other potential confounding factors. Results A significant direct relation was observed between starch intake (OR 1.51, 95% CI 1.15 to 1.99 for highest quintile compared with lowest one), and an inverse relation was observed for polyunsaturated fatty acids (OR 0.72, 95% CI 0.55 to 0.93), linoleic acid (OR 0.73, 95% CI 0.56 to 0.94), and linolenic acid (OR 0.71, 95% CI 0.54 to 0.93). Conclusions The results of this study suggest a role for specific macronutrients in the risk of BPH, including, in particular, an unfavorable effect for starch and a beneficial one for polyunsaturated fatty acids.

Flavonoids have been associated with a reduced risk of lung, digestive tract, and certain hormone-related cancers. With reference to prostate cancer a few epidemiological studies have found an inverse relation with intake of isoflavones, flavonols, and flavones, although the evidence remains limited and inconsistent. The role of six principal classes of flavonoids on prostate cancer was investigated using data from a multicentric case-control study conducted between 1991 and 2002 in Italy. This included 1,294 incident, histologically confirmed carcinomas of the prostate and 1,451 controls admitted to the same hospitals as cases for a wide spectrum of acute, non-neoplastic conditions. The patients' usual diet was assessed using a validated and reproducible food-frequency questionnaire; food and beverage content of six major classes of flavonoids was obtained from the US. Department of Agriculture. No association between prostate cancer risk was found with any of the flavonoids analyzed: the multivariate odds ratios for the highest versus the lowest quintile of intake were 0.96 (95% confidence interval,, CI = 0.75-1.23) for flavanones, 1.3 (95% CI = 1.01-1.69) for flavan-3-ols, 1.23 (95% CI = 0.95-1.61) for flavonols. 1.09 (95% CI = 0.85-1.40) for flavonols, 1.18 (95% CI = 0.91-1.53)for anthocyanidins, 0.98 (95% CI = 0.76-1.26) for isoflavones, and 1.20 (95% CI = 0.92-1.58) for total flavonoids, all nonstatistically significant. Thus, the results of the present study do not support a protective effect of flavonoids on prostate cancer in this Italian population, characterized by a high intake of flavonoid-containing foods (except isoflavone-rich foods).

Objective: Our aim was to investigate the reliability of the information on family history of cancer in first-degree relatives in a hospital-based case-control study. Study Design and Setting: We re-interviewed at home 294 controls of an Italian hospital-based case-control study on digestive tract neoplasms using the same questionnaire and compared the responses reported by these patients in the two settings. Results: A satisfactory agreement between the two interviews was reported for family history of any cancer (kappa = 0.7) and of cancers of the digestive tract (kappa = 0.8). The agreement was apparently higher for esophageal and stomach cancers (kappa > 0.8) than for intestinal cancers (kappa = 0.6) and lower for lung cancer (kappa = 0.5). We found a systematic tendency to report a history of cancer more frequently in the hospital setting than in the home setting. Conclusion: The present study showed a good reliability of data on family history of all cancers, including cancers of the digestive tract, provided by hospital controls through a structured interview-administered questionnaire. It suggests, moreover, that controls in the hospital setting tend to recall more often, and presumably more completely, a family history of cancer. (c) 2007 Elsevier Inc. All rights reserved.

An inverse association has been reported between coffee drinking and the risk of hepatocellular carcinoma (HCC) and chronic liver disease (CLD), but its magnitude is still unclear. Thus, we carried out a systematic review and meta-analysis of prospective cohort studies that investigated the association between coffee consumption and the risk of HCC or CLD. We separately estimated the relative risk (RR) of the two conditions, for regular, low, and high consumption compared with no or occasional coffee consumption; we also calculated the summary RR for an increment of one cup of coffee per day. Twelve studies on HCC (3414 cases) and six studies on CLD (1463 cases) were identified. The summary RRs for HCC were 0.66 [95% confidence interval (CI): 0.55-0.78] for regular, 0.78 (95% CI: 0.66-0.91) for low, and 0.50 (95% CI: 0.43-0.58) for high coffee consumption, respectively. The summary RR for an increment of one cup per day was 0.85 (95% CI: 0.81-0.90). The summary RRs for CLD were 0.62 (95% CI: 0.47-0.82) for regular, 0.72 (95% CI: 0.59-0.88) for low, 0.35 (95% CI: 0.22-0.56) for high, and 0.74 (95% CI: 0.65-0.83) for an increment of one cup per day. The present meta-analysis provides a precise quantification of the inverse relation between coffee consumption and the risk of HCC, and adds evidence to the presence of an even stronger negative association with CLD. © 2017 Wolters Kluwer Health, Inc.
