Introduction: Rates of sexually-transmitted infections (STIs) remain high among men who have sex with men (MSM), posing serious public health concerns. The MSM population is recognized as a vulnerable, high-risk group due to barriers to preventive healthcare services and homophobic stigma., Methods: A cross-sectional online survey was conducted using a questionnaire based on European Man-for-Man Internet Survey 2010 (EMIS 2010) and European Centre for Disease Prevention and Control (ECDC) core indicators specific for behavioral risks. MSM were reached between June and August 2017, using Facebook and dating apps. Descriptive statistics and multivariate logistic regression were used to analyze the data., Results: A total of 324 respondents were analyzed, 88 subjects (27.2% of the sample) reported having experienced at least one STI, the most common being gonorrhea and HPV. Ten respondents reported having HIV infection, and 7 subjects (70%) of them were co-infected with other STIs. The 49.7% (161 subjects) had seen a doctor specifically for STIs. As concerns HPV vaccination, only 4.0% of the total respondents had been vaccinated. Restricting the sample to the 161 respondents who consulted an STI clinic, the 88 individuals who reported having had at least one STI amount to 54.6%. A more consistent use of condoms and larger numbers of sexual partners were significantly associated with a lower and higher risk of STI, respectively., Conclusions: Comprehensive STI prevention strategies are needed to improve sexual health among MSM. Such strategies should include implementing programs to improve awareness about routine screening, and promote a consistent use of condoms by MSM., (©2019 Pacini Editore SRL, Pisa, Italy.)

In June 2009, the World Health Organization (WHO) issued a pandemic alert concerning the spread of an influenza A (H1N1) virus that showed distinctive genetic characteristics vis-à-vis both seasonal influenza strains and vaccine strains. The main mutation occurred in the gene coding for hemagglutinin (HA). Mathematical models were developed to calculate the transmissibility of the virus; the results indicated a significant overlap with the transmissibility of previous pandemic strains and seasonal strains. The remarkable feature of A/(H1N1)pdm09, compared with seasonal strains, is its high fatality rate and its higher incidence among younger people. Data provided by the WHO on the number of deaths caused by A/(H1N1)pdm09 only include laboratory-confirmed cases. Some authors suggest that these data could underestimate the magnitude of the event, as laboratory confirmation is not obtained in all cases. It is important to bear in mind that the A/(H1N1)pdm09 virus is still circulating in the population. It is therefore essential to maintain its epidemiological and virological surveillance.

Introduction: Pneumonia remains a common reason for hospitalizing infants and the elderly worldwide, and streptococcal infection is often responsible. The aim of this study was to assess the burden of pneumonia in a large general population., Methods: All pneumonia-related hospitalizations from 2004 to 2013 in north-east Italy were identified from the hospital records with a first-listed diagnosis on discharge of bacterial pneumonia, or a first-listed diagnosis on discharge of meningitis, septicemia or empyema associated with a secondary diagnosis of bacterial pneumonia. We identified major comorbidities, calculated agespecific case-fatality rates (CFR), and estimated the related cost to the health care system., Results: Of the 125,722 hospitalizations identified, 96.9% were cases of pneumonia, 2.4% of septicemia, 0.4% of meningitis, and 0.3% of empyema; 75.3% of hospitalizations involved ≥ 65-yearolds. The overall CFR was 12.4%, and it increased with age, peaking in people over 80 (19.6%). The mean annual pneumonia-associated hospitalization rate was 204.6 per 100,000 population, and it peaked in 0- to 4-year-old children (325.6 per 100,000 in males, 288.9 per 100,000 in females), and adults over 65 (844.9 per 100,000 in males, 605.7 per 100,000 in females). Hospitalization rates dropped over the years for the 0-4 year-olds, and rose for people over 80. The estimated overall annual cost of these pneumonia-related hospitalizations was approximately € 41 million., Conclusions: This study shows that the burden on resources for pneumonia-related hospitalization is an important public health issue. Prevention remains the most valuable tool for containing pneumonia, and vaccination strategies can help in the primary prevention of infection, possibly reducing the number of cases in all age groups.

Introduction: Since Regione Veneto suspended compulsory vaccination for children in 2008, and because of an increasing disaffection of parents to the vaccine practice, the vaccination rates have been slowly but steadily decreasing. The aim of this study was to analyze internal and external factors of immunization reduction and to implement potential solutions of the problem., Methods: Servizio Igiene e SanitàPubblica of ULSS 12 Venezi-na (SISP - Hygiene and Public Health Service) analyzed and addressed both, the reasons of parents who do not vaccinate their children and the internal problems regarding vaccination clinics management, information to families, procedures and guidelines and, in general, the communication skills of the vaccination staff., Results: A positive trend in vaccination rates was observed, especially in Venice historical centre. Moreover the staff reported a better working atmosphere and benefit from sharing common goals and procedures, even though the workforce was reduced of about 30% in terms of equivalent unit (EU)., Discussion: The continuous quality improvement method followed in this experience led to a steady increase in vaccination coverage in all territorial clinics, to a better adhesion of guidelines and standard operating procedures and to a general professional empowerment of SISP staff. The service now offered to the population is better and more efficient, since the workforce has been reduced. Future goals are to improve information about vaccinations among the population.

The goal of this study was to describe and comment the experience of the Veneto Region in the bacterial invasive disease. Vaccination coverage was 93% against pneumococcus and 95% against haemophilus influenzae type B. Regard to meningococcus C the coverage rate was 90.1% In children, 81% at 6 years of age and 78.2% at 15 years. The preliminary data of an active surveillance of invasive bacterial diseases show that the Streptoccoccus pneumoniae was the main agent involved and that its consequences were particularly serious in elderly subjects. With regard to Neisseria meningitidis, we observed a substantial reduction in the number of cases due to serogroup C and a concomitant rise in the percentage of cases due to serogroup B. The suspension of mandatory vaccination should be maintained, the monitoring of vaccination coverage and the active surveillance proved to be a very good assessment tools.
