Introduction: In November 2010 the Mediterranean Diet was recognized by the UNESCO as Intangible Cultural Heritage of Humanity. It is an heritage that brings together the dietary habits of the peoples of the Mediterranean countries, consolidated over the centuries remained almost unchanged until the 1950s. Numerous scientific studies have also shown that the Mediterranean Diet is an healthy diet that helps to prevent the main chronic diseases such as cardiovascular diseases, diabetes, bulimia and obesity and thanks to the antioxidant power of olive oil combined with vegetables consumption, an important means of cancer prevention. The aim of our study was to investigate the knowledge and the adherence to the Mediterranean diet of young people living in the Mediterranean area., Materials and Methods: The survey was carried out by administering a web-based anonymous questionnaire from March to May 2019 to Italian young people. In this survey we asked for socio-economic conditions, knowledge, awareness and adherence to the Mediterranean diet (through the KIDMED test) both in childhood and at present time. Parental educational status and family income were used as indicators of socio-economic status (SES)., Result: The sample was made up by 507 Italian young people between the ages of 17 and 35 (123 males and 384 females), with an average age of 22.88 years (DS 7.02). Only 11.4% knew the Mediterranean diet. During childhood 70.8% of respondents had breakfast and 58% ate fruit and vegetables daily. Today they have maintained the correct eating habits, in fact, 71.2% had breakfast, 60.2% ate fruit and 64.7% ate vegetables. In addition, only 48.3% eat fish and the majority of respondents consume carbohydrates (76.9%). To a lesser extent they consume junk foods like candy and various snacks (18.1%) or fast food meals (9.1%). Moreover, we asked for physical activity and we found that 48.9% did it. We found age, exercise and sex high significant variables (p<0.01). Higher adherence to MD was found in older interviewees., Conclusion: Our study we found high knowledge to a Mediterranean diet into 90.5% of the sample and poor adherence into 23.5% of them, medium into 53.4% while higher only in 23.1% of the interviewees. Lower adherence was found among those who do not engage in physical activity and the two regressor with higher weight on the adherence to MD were "eat at home "and "eat fruit and vegetables". Furthermore, in our sample more increased the age more increased adherence to traditional diet models.

Introduction: Surgical site infections are among the most frequent Health Care Associated Infections with severe impact on mortality and high economic costs; the role of air microbiological contamination in surgical site infections was amply discussed in the scientific literature, highlighting differences in air contamination rates between different ventilation systems, number of people present and door opening rates., Material and Methods: The aim of our study was to monitor the presence of bacterial air contamination in operating theaters and its relationship with number of people and type of airflow over a period of nine years (January 2010-November 2018) at Messina's University Hospital. The Rho of Spearman test was used to evaluate differences in microbial contamination between empty and working theaters. The impact of the number of people on colony-forming unit values was assessed by performing a stepwise multiple regression analysis. The differences between the results recorded over the nine-year study period were evaluated using the variance analysis. Software R was used for the statistical assessment., Results: Air samples were taken in each operating theater over nine years. A total of 1,425 samples were collected with a positivity rate of 37.3%. The median bacterial contamination rate was 30 cfu/m3 in empty theaters, while this rate was significantly higher (P < 0.001) in working theaters, where it reached 85 cfu/m3. A statistically significant difference was identified between laminar and turbulent airflow systems, with higher bacterial contamination rates with the latter (p<0.001); in these cases, the value of bacterial contamination (microbial count) was higher in the presence of a higher number of individuals in the operating theater (p<0.001)., Conclusion: Our study demonstrates the complexity of the Operating Theatres environment, in which a good ventilation system is, indeed, only one prerequisite for clean air, but other factors, such as the behavior of healthcare professionals and environmental conditions, can influenced the bacterial count.

The National Plan for Vaccine Prevention 2017-2019 has expanded the vaccination offer including new vaccines, enlarging the target population and introducing for the first time in Italy a life-course approach to vaccination. A "lifetime immunization schedule" is aimed to reduce the burden and the related costs of vaccine-preventable diseases through effective vaccination programs. However, to counteract the national steady downward trend in the uptake of vaccinations that caused a drop of the vaccination coverage below the 95% threshold to allow herd immunity, it was decided to make 10 vaccinations mandatory by the law 119/2017. In particular, in addition to already mandatory vaccinations against diphtheria, tetanus, hepatitis B and poliomyelitis, those against measles, mumps, rubella (MMR), varicella, pertussis and Haemophilus influenzae type b (Hib) were added to the list. According to the law, all unvaccinated children cannot attend preschool services until the age of 6 years and fines (from 100 to 500 Euros) are provided for parents. Moreover, this law provided, in its first application, a catch-up campaign for children up to the age of 16 years and the free-of-charge offer of all mandatory and recommended vaccines to each child not yet vaccinated according to the previous NPVP. The NPVP includes also several at risk categories, such as pregnant women, healthcare workers and subjects suffering from chronic diseases, to whom specific vaccinations, free of charge, are offered. The vaccinations of pregnant women have different purposes. In order to decrease the pertussis risk in newborns in the first months of life, a booster immunization of DTPa is recommended, at every pregnancy, between week 27th and 36th. Instead, the influenza vaccine administration to pregnant women during the second or third quarter is mainly aimed to avoid the risk of serious disease complications for both the mother and the fetus. Another group of at risk subjects included in the NPVP is that made up by healthcare workers. According to the plan, "an adequate immunization of the healthcare workers is essential for the prevention and control of infections (anti-hepatitis B, anti-influenza, anti-measles-mumps-rubella, anti-varicella, anti-pertussis)". Finally, almost all the vaccinations foreseen by the NPVP are offered free of charge to subjects suffering from specific diseases. These include cardiovascular, respiratory, hepatic, neoplastic, renal and metabolic disorders, in addition to immunosuppression that exposes them to an increased risk of contracting invasive infectious diseases.

Background: The World Health Organization's Action Framework for tuberculosis elimination in low-tuberculosis incidence countries includes the screening for active and latent tuberculosis in selected high-risk groups, including health care workers. In this context, medical and health profession students, exposed to nosocomial tuberculosis transmission during training and clinical rotations, are target populations for tuberculosis screening. No updated data are available on tuberculosis screening practice and knowledge of medical and health profession students in Italy., Methods: Within the activities Italian Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health, we carried out a multicentre cross-sectional study to assess knowledge, attitude and practices on tuberculosis prevention and control among Medical, Dentistry, Nursing and other health professions' students. Students were enrolled in the study on a voluntary basis and were administered a previously piloted structured questionnaire. Logistic regression models were applied to explore knowledge on tuberculosis prevention by selected socio-demographic variables and University-based tuberculosis prevention practice., Results: Students of seventeen Universities across Italy participated in the study, and 58.2% of them received compulsory tuberculin skin test either at enrollment or while attending clinical practice. A total of 5,209 students filled the questionnaire. 37.7% were medicine and dentistry students (Group 1), 44.9% were nursing students (Group 2) and 17.4% were other health professions' students (Group 3). Age and gender had different distributions by groups, as well as knowledge and practice on tuberculin skin test. 84.4% of the study population (95% CI = 83.3-85.3) was aware of the existence of the tuberculin skin test, 74.4% (95% CI = 73.2-75.6) knew what is the first-level screening test for latent tuberculosis and only 22.5% (95% CI = 21.4-23.6) knew how to proceed after a positive tuberculin skin test result. Overall, knowledge on tuberculosis prevention was higher in Group 2 and lower Group 3, as compared to Group 1., Conclusion: In Italy, the knowledge on tuberculosis screening among University students is generally good. To reduce some of the criticalities found among the different study courses, it would be appropriate to harmonize both the regulations on tuberculosis screening practices for admission to University courses, and the educational activities on the topic of tuberculosis, to be extended to all workers involved in health care setting.
