RESUMO
BACKGROUND AND AIM: On January 9, 2020, the World Health Organization (WHO) declared that Chinese health authorities had identified a new coronavirus strain never before isolated in humans, the 2019-nCoV later redefined SARS-CoV-2, that still today represent a public health problem. The present survey started on 10 February 2020 with the aim of a) assessing the risk perception in healthcare workers and young students, following the evolution of attitudes, perception and knowledge over time, b) provide useful information to the general population during survey. RESULTS: A study sample consisting of 4116 Italian individuals of both sexes was enrolled. High levels of risk perception, low perception of self-efficacy and low levels of knowledge scores (24.55 ± 5.76 SD) were obtained indicating the need for continuous population monitoring as well as further communication strategies carried out at institution levels. CONCLUSION: The results of the present study could help public health authorities in carrying out informative campaigns for general population and could be an important tool in evaluating public knowledge and misperceptions during the management of the COVID-19.

PURPOSE: Adolescence overweight and obesity have increased considerably, and the misperception of their weight status could reduce the efficiency of intervention programs. The aim of this study was to evaluate the prevalence rate of misperception and to assess the relationship between weight perception and anthropometric parameters, self-perception, physical activity, and adherence to the Mediterranean diet. METHODS: A total of 1643 young adolescents (11-16 years old) were surveyed in a cross-sectional investigation during two scholastic years (period October-May of 2012-2013 and 2013-2014) in 15 secondary schools of Sicily, southern Italy. Data on demographic information, anthropometric characteristics (bioelectrical impedance), physical activity level, The Children and Youth Physical Self-Perception Profile, weight perception, and dietary habits (KIDMED) were collected. RESULTS: Misperception was found in the 27.6 % of the young adolescents, and boys were more likely to underestimate their weight status, while girls had a high percentage of overestimation. The strong association with weight misperception was with socioeconomic status, waist circumference, physical activities, and physical self-worth. Moreover, a good adherence to the Mediterranean diet was inversely associated with both overestimation and underestimation in both boys and girls. CONCLUSION: These findings highlight that almost one-third of the participants had a weight misperception that was associated with several anthropometric, social, and lifestyle factors. Future intervention to prevent overweight and obesity should consider not only gender-specific differences, but also parental SES, perception, and satisfaction of body weight status.

A decline in adherence to the Mediterranean dietary pattern has been observed over the last years. The aim of this study was to assess the level of adherence to the Mediterranean diet and possible determinants in the Mediterranean healthy Eating, Aging and Lifestyle (MEAL) study cohort. Demographic and dietary data of 1937 individuals were collected in 2014-2015 from the general population of Catania, Sicily (Italy). Food frequency questionnaires and the MEDI-LITE score were used to assess adherence to the Mediterranean diet. The score well characterised consumption of major food groups, micro- and macro-nutrients. The cohort had a general good adherence, but only a minority was highly adherent. High adherence was directly associated with education, non-smoking and physical activity and inversely with high occupational status. In conclusions, Mediterranean diet is still followed in Sicily; however, nutrition education campaigns should promote healthy traditional dietary patterns in certain groups of individuals.

The aim of this study was to estimate the dietary intake and major food sources of polyphenols in the Mediterranean healthy Eating, Aging and Lifestyles (MEAL) study cohort. A total of 1937 individuals (18 + y) of urban population of Catania, Italy, completed a validated 110-item food frequency questionnaire; Phenol-Explorer database was used to estimate polyphenol intake. Mean intake of polyphenols was 663.7 mg/d; the most abundant classes were phenolic acids (362.7 mg/d) and flavonoids (258.7 mg/d). The main dietary sources of total polyphenols were nuts, followed by tea and coffee as source of flavanols and hydroxycinnamic acids, respectively, fruits (i.e. cherries were sources of anthocyanins and citrus fruits of flavanones) and vegetables (i.e. artichokes and olives were sources of flavones and spinach and beans of flavonols); chocolate, red wine and pasta contributed to flavanols and tyrosols, respectively. These findings will be useful to assess the potential benefits of foods with high polyphenol content.

INTRODUCTION: Adherence to the traditional Mediterranean diet has been associated with health benefits in young populations. The aim of this study was to evaluate the association between adherence to the Mediterranean diet and cardio-metabolic parameters in adolescents living in Sicily, Southern Italy. METHODS: A cross-sectional study was conducted during two school years (2012-2013 and 2013-2014) on 1643 adolescents of 11-16 years attending 15 secondary schools. Socio-demographic, dietary, lifestyle, and anthropometric data were collected. The KIDMED score was used to evaluate the adherence to the Mediterranean diet. Linear and logistic regression models were used to test the association between the variable of interest and the outcomes. RESULTS: A higher percentage of boys compared with girls was overweight (30.8% vs. 25.4%) and obese (28.7% vs. 18.5%) and only 9.1% had high adherence to the Mediterranean diet. Vegetable intake was negatively associated with being overweight/obese whereas higher intake of sweets, sugar-sweetened beverages, and fast foods was associated with overweight and obesity. A good adherence to the Mediterranean diet resulted in 30% decreased odds of being overweight or obese (odd ratio 0.70, 95% confidence interval: 0.56-0.87) in both boys and girls. An inverse correlation was found between KIDMED score and BMI, waist circumference and fat mass. No relation with blood pressure was found. CONCLUSIONS: Mediterranean dietary pattern resulted significantly associated with weight status in adolescents. These results underline the importance of providing lifestyle and dietary habits education to prevent overweight and obesity in adolescent.

There is accumulating evidence suggesting that Mediterranean lifestyles, including nutrition and sleeping patterns as well as social integration, may play a role in reducing age-related diseases. However, the literature is mostly deficient of evidence provided by Italian Mediterranean islands that more closely adhered to the originally described lifestyles. In this paper, we described the rationale and the study design of the Mediterranean healthy Eating, Ageing, and Lifestyle (MEAL) study, a prospective population-based cohort established in Sicily, southern Italy. The main exposures investigated are classical determinants of health, including demographic, nutritional habits, smoking and physical activity status, as well as eating-related behaviors, sleeping habits, sun exposure, social resources, and perceived stress. Anthropometric measurements will be collected. The main outcomes included depression, quality of life, and, after the follow-up period, also cardiovascular disease and cancer. The MEAL study may provide important data to increase our knowledge regarding the prevalence, incidence, and risk factors of age-related disorders in the Mediterranean region.

The aim of this study was to evaluate the association between sleeping habits, Mediterranean diet pattern, and weight status in an adolescent population. The sample consisted of 1586 individuals aged 11-14 years attending 15 secondary schools of Sicily, Southern Italy. School were randomly selected and the data collected during two school years. Anthropometric data was collected and body composition was assessed by bioelectrical impedance analysis. Demographic information, sleep duration, pediatric daytime sleepiness questionnaire (PDSS), physical activity and dietary habits (including adherence to the Mediterranean Diet using the KIDMED score) were further collected. The mean age was 12±0.7 and about 24% were overweight and obese. An inverse correlation between total sleep time and body mass index (ß=-0.829, P=0.021), fat mass (ß=-0.526, P=0.025), and waist circumference (ß=-0.426, P=0.045) was found. Similar results were found for weekdays sleep time, while an inverse relationship was found with PDSS score. Adherence to Mediterranean Diet was higher in under/normal weight adolescent with a significant linear association between the KIDMED score and the PDSS, weekdays sleep time and total sleep time. Sleep duration was also associated positively with fruits and vegetable intake and negatively with sweet and snack consumption and eating outside habits. Short sleep duration and poor sleep were associated with an increase in BMI and fat mass as well as to unhealthy eating behaviors. These findings suggest that sleep patterns could be a potential target for obesity prevention programs in young adolescence.
RESUMO
BACKGROUND: Fish consumption and n-3 polyunsaturated fatty acids (PUFA) have been hypothesized to exert preventive effects toward depressive disorders, but findings are contrasting. We aimed to systematically review and perform meta-analysis of results from observational studies exploring the association between fish, n-3 PUFA dietary intake, and depression. METHODS: A search on the main bibliographic source of the observational studies up to August 2015 was performed. Random-effects models of the highest versus the lowest (reference) category of exposure and dose-response meta-analysis were performed. RESULTS: A total of 31 studies including 255,076 individuals and over 20,000 cases of depression, were examined. Analysis of 21 datasets investigating relation between fish consumption and depression resulted in significant reduced risk (RR=0.78, 95% CI: 0.69, 0.89), with a linear dose-response despite with moderate heterogeneity. Pooled risk estimates of depression for extreme categories of both total n-3 PUFA and fish-derived n-3 PUFA [eicosapentaenoic acid (EPA)+docosahexaenoic acid (DHA)] resulted in decreased risk for the highest compared with the lowest intake (RR=0.78, 95% CI: 0.67, 0.92 and RR=0.82, 95% CI: 0.73, 0.92, respectively) and dose-response analysis revealed a J-shaped association with a peak decreased risk for 1.8g/d intake of n-3 PUFA (RR=0.30, 95% CI: 0.09, 0.98). LIMITATION: Design of the studies included and confounding due to lack adjustment for certain variables may exist. CONCLUSIONS: The present analysis supports the hypothesis that dietary n-3 PUFA intake are associated with lower risk of depression.

The aim of this study was to develop and test the reliability and relative validity of a food frequency questionnaire (FFQ) specifically developed for individuals living in Sicily, southern Italy. This study was conducted on a convenient sample of 178 adult volunteers aged 18-80 years recruited in the urban population of Catania. Dietary intake estimated by 2 FFQs was compared with six 24-h recalls covering a period of 10 months. A total of 110 food items were included in the FFQ. Person's coefficients between the first FFQ and mean of the six 24-h recalls showed high correlations for coffee, tea, pasta and dairy products, alcohol, total fats and carbohydrates (in women). The test-retest analysis showed high reproducibility of the FFQ. We showed that our FFQ provided a useful estimate of both food and nutrient intake in a healthy adult population.

BACKGROUND & AIMS: Diet plays a role in the onset and progression of metabolic disorders, including non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS). We aimed to systematically review and perform quantitative analyses of results from observational studies on coffee/tea consumption and NAFLD or MetS. METHODS: A Medline and Embase search was performed to retrieve articles published up to March 2015. We used a combination of the keywords "coffee", "caffeine", "tea", "non-alcoholic fatty liver disease", "non-alcoholic steatohepatitis", "metabolic syndrome". Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated by random-effects model. RESULTS: Seven studies assessed coffee consumption in NAFLD patients. Fibrosis scores were reported in four out of seven; all four studies revealed an inverse association of coffee intake with fibrosis severity, although the lack of comparable exposure and outcomes did not allow to perform pooled analysis. Seven studies met the inclusion criteria to be included in the meta-analysis on coffee consumption and MetS. Individuals consuming higher quantities of coffee were less like to have MetS (RR = 0.87, 95% CI: 0.79-0.96). However, the association of coffee and individual components of MetS was not consistent across the studies. Pooled analysis of six studies exploring the association between tea consumption and MetS resulted in decreased odds of MetS for individuals consuming more tea (RR = 0.83, 95% CI: 0.73-0.95). CONCLUSIONS: Studies on coffee and NAFLD suggest that coffee consumption could have a protective role on fibrosis. Both coffee and tea consumption are associated with less likelihood of having MetS but further research with better designed studies is needed.

Bacterial regrowth in water distribution systems results in deterioration of bacteriological quality of drinking water, as well as accelerated corrosion of the pipelines. The aim of the present study was to analyze the phenomena of colonization and bacterial regrowth in source water and in the water distribution systems of three distribution networks in the province of Catania (Sicily, Italy). The BART™ (Biological Activity Reaction Test) method was used, which is also capable of determining the potential aggressiveness of microbial species in water. We searched for sulfate reducing bacteria, iron-related bacteria, nitrifying and denitrifying bacteria, heterotrophic bacteria, slime-forming bacteria and fluorescent Pseudomonads. A high concentration of heterotrophic bacteria was found in almost every water sample analyzed. Sulfate reducing bacteria and iron-related bacteria were found in all three distribution networks, while non-fluorescing Pseudomonas were detected in source water of only one of the distribution networks. The BART™ method was found to be a practical and easy to use tool to detect the different bacteria groups involved in regrowth phenomena.

Polyunsaturated fatty acids (PUFAs) have been considered of great interest for human health due to their potential anti-inflammatory action that may protect from a number of chronic-degenerative diseases with an inflammatory pathogenesis. This review aimed to report the most updated evidence of both n-3 and n-6 PUFAs effect on cardiovascular disease, cancer, and depression in humans. Attention has been also paid to those studies exploring the effects of the ratio intake. Results from pooled analyses of human studies reported a general positive effect of n-3 PUFAs intake on all outcomes considered. In contrast, the role of n-6 PUFAs on human health needs to be better assessed in order to clearly identify which compound exerts beneficial/harmful effects. Only a limited number of clinical studies considered the n-3:n-6 PUFAs ratio, rather reporting contrasting results. A number of limitations when considering the ratio between these two families of PUFAs have risen.

INTRODUCTION: Cancer survival is related not only to primary malignancy but also to concomitant nonmalignant diseases. The aim of this study was to investigate the prognostic capacity of four comorbidity indices [the Charlson comorbidity index (CCI), the Elixhauser method, the National Institute on Aging (NIA) and National Cancer Institute (NCI) comorbidity index, and the Adult Comorbidity Evaluation-27 (ACE-27)] for both cancer-related and all-cause mortality among colorectal cancer patients. A modified version of the CCI adapted for colorectal cancer patients was also built. METHODS: The study population comprised 468 cases of colorectal cancer diagnosed between 1 January 2000 and 31 December 2010 at a community hospital. Data were prospectively collected and abstracted from patients' clinical records. Kaplan-Meier method and multivariate logistic regression models were performed for survival and risk of death analysis. RESULTS: Only moderate or severe renal disease [hazard ratio (HR) 2.71, 95% confidence interval (CI) 1.11-6.63] and AIDS (HR 3.27, 95% CI 1.23-8.68) were independently associated with cancer-specific mortality, with a population attributable risk of 5.18 and 4.36%, respectively. For each index, the highest comorbidity burden was significantly associated with poorer overall survival (NIA/NCI: HR 2.14, 95% CI 1.14-4.01; Elixhauser: HR 1.98, 95% CI 1.09-1.42; ACE-27: HR 1.78, 95% CI 1.07-1.23; CCI: HR 1.68, 95% CI 1.05-1.42) and cancer-specific survival. The modified version of the CCI resulted in a higher predictive power compared with other indices studied (cancer-specific mortality HR = 2.37, 95% CI 1.37-4.08). CONCLUSIONS: The comorbidity assessment tools provided better prognostic prevision of prospective outcome of colorectal cancer patients than single comorbid conditions.

BACKGROUND: Intake of caffeinated beverages, such as coffee and tea, has been related to improvements in components of metabolic syndrome (MetS), but studies conducted in the Mediterranean region are scarce. The aim of this study was to evaluate whether or not consumption of a variety of beverages containing caffeine was associated with components of MetS in an Italian population. METHODS: From May 2009 to December 2010, a cross-sectional survey was conducted on 1889 inhabitants living in Sicily, southern Italy. Data regarding demographic characteristics, habitual beverage intake, and adherence to the Mediterranean diet were collected, and clinical information was retrieved from the general practitioners' computer records. RESULTS: After adjusting for all covariates, coffee (odds ratio [OR] 0.43, 95% confidence interval [CI] 0.27-0.70) and tea (OR 0.51, 95% CI 0.34-0.78) were associated with MetS, whereas no association was observed between caffeine intake and MetS. Among other factors, age, body mass index, physical activity, current smoking, and adherence to Mediterranean diet were associated with having MetS. Triglycerides were inversely associated with consumption of both espresso coffee and tea. The healthy effects of such beverages were more evident in individuals with unhealthy dietary habits. CONCLUSIONS: Although no direct association between caffeine intake and MetS or its components was observed, coffee and tea consumption was significantly related to reduced odds of MetS.

Recent evidence demonstrates that increased adherence to the Mediterranean diet (MD) may prevent colorectal cancer (CRC). The aim of this study was to evaluate the association between health-related characteristics and CRC in the context of the MD. This was a case-control study conducted on a sample of 338 consecutive patients with a first diagnosis of CRC recruited in an urban facility in the city of Catania, southern Italy, and matched with 676 apparently healthy subjects without clinical symptoms or signs of any type of cancer. Data regarding sociodemographic, clinical, and lifestyle characteristics were collected, and adherence to the Mediterranean diet pattern was assessed using the MedDietScore. A significant association between a greater adherence to the MD and lower odds of having cancer (odds ratio = 0.46, 95% confidence interval: 0.28-0.75) was found. Also, smoking status, family history of CRC, obesity, diabetes, physical activity, and high intake of alcohol were significantly associated with CRC, but only among subjects less adherent to the MD. MD was associated with a less detrimental effects of several health-related characteristics associated with CRC, suggesting potential benefits of adherence to this dietary pattern with regards to CRC risk factors.

This study investigated risk factors and impact of open conversion on outcomes of 207 consecutive patients who had laparoscopic resection of colorectal cancer at our institution. Conversion occurred in 15.9% of patients, mostly because of invasion to adjacent structures (30.3%), bulky tumor (21.2%), and adhesions (18.2%). Converted patients had significant larger tumor size, advanced stage, increased operative blood loss, time to walk independently, prolonged hospital stay, number of massive hemorrhage, ileus, anastomotic hemorrhage, abdominal hemorrhage, peritonitis/septic shock, and wound infection than completed laparoscopy patients. Factors associated with conversion were obesity [relative risk (RR)=6.92; 95% confidence interval (CI), 1.7-28.09], date of operation (RR=0.37; 95% CI, 0.15-0.95), advanced tumor stage (RR=7.67; 95% CI; 1.19-49.2), size (RR=1.97; 95% CI, 1.42-2.72), and rectum location (RR=2.73; 95% CI, 1.09-6.84). Converted patients had worse cumulative disease-free (P<0.001) and overall survival (P<0.001) than laparoscopic completed patients.

The aim of this paper was to systematically review and analyze the epidemiological evidence on the role of Mediterranean diet (MD) in the prevention of cardiovascular diseases (CVD). Fifty-eight studies exploring the relation between MD and lipoprotein concentration, antioxidative capacity and inflammatory markers, hypertension, obesity, diabetes, and metabolic syndrome, were identified and selected. These included 33 cross-sectional, 9 cohort, and 16 intervention studies. Most of the studies showed favorable effects of MD on CVD, although a certain degree of controversy remains in the respect of some issues, as obesity. Important methodological differences and limitations in the studies make difficult to compare results, thus further studies, particularly randomized clinical trials, are needed to finally substantiate the benefits of MD and to shed some lights on mechanisms.
