Attitudes and perceptions of Italian Students in Healthcare Settings on COVID-19 vaccines and vaccinations strategies, one year after the immunization campaign.

Background: The topic of vaccine confidence is increasingly relevant, particularly due to the COVID-19 pandemic and the global distribution of COVID-19 vaccines. This issue is even more critical for students in healthcare settings, given their future role not only as vaccine recipients but also as advocates for vaccination. In light of this, achieving a good level of vaccine acceptance is crucial. Hence, the aim of our study was to evaluate the attitudes and perceptions of healthcare students regarding vaccines and COVID- 19 vaccination. Methods: Medical and pharmaceutical area students attended an Elective Teaching Activity on COVID-19 vaccines and vaccination campaign, organized at the University of Florence (Italy) and participated in filling two anonymous questionnaires. The first questionnaire was submitted before the Elective Teaching Activity was focused on students' attitudes and perceptions toward vaccines. The second questionnaire was designed to evaluate the students' satisfaction with the course topics. Both descriptive and inferential analyses were performed on the results. In addition, the Vaccine Confidence Index was calculated to evaluate the propensity of students toward vaccinations. Results: A total of 423 students attended the Elective Teaching Activity in the early beginnings of 2022. Overall, students have shown greater confidence in vaccines, compared to COVID-19 vaccines, especially as regards the safety profile. Students' Vaccine Confidence Index was very close to 0.25 value, which indicates being in favor of vaccinations. Nevertheless, in the satisfaction questionnaire filled in at the end of the course, the percentage of students in favor of COVID-19 vaccination increased for both medical (from 94% to 99%) and pharmaceutical area students (from 81% to 97%). Conclusions: Our study suggests that educational activities such as this Elective Teaching Activity, could be considered an effective teaching strategy to improve vaccine acceptance rates among students in healthcare settings.

Six years of activity of the Italian vaccine portal "VaccinarSì": a web traffic evaluation using Google Analytics.

BACKGROUND: Despite the scientific consensus about vaccines safety and effectiveness, there is still a discrepancy between scientific evidence and perception by the general population. The "VaccinarSì" portal was created in 2013 by Italian specialists in Public Health to provide evidence-based information regarding vaccination. STUDY DESIGN: The purpose of this study was to analyse the web traffic on "VaccinarSì" platform during a six-year period (May 8, 2013-May 8, 2019). Moreover, we compared the first six-month with the last six-month period of the website activity, to identify potential areas of improvements. METHODS: This is a descriptive study using Google Analytics data. We collected data regarding the following: total number of sessions to the portal, total number of pages viewed, total number of users and the number of new visitors, geographical locations and demography of users as well as user access mode (type of device used and way of access). We also collected some data that were informative about the possibility to infer the level of visitors' engagement with the portal, such as thee number of returning users, bounce rate, number of pages visited per session and mean session duration. RESULTS: Throughout the relevant period, the portal has consistently increased its popularity, with a remarkable increment of monthly connections (ending up to more than 80,000/month) from all over Italy. Visitors were mainly female (71.1%), aged between 25 and 44 years (64.7%). Healthcare professionals were responsible for a considerable proportion of accesses (50.6%). The mobile has become the dominant device used to access the portal, accounting for 77.8% of total connection in the last six months. Similarly, in the last period, organic search accounted for 92% of all connections. Measles and MPR vaccine, as well as chickenpox and hexavalent vaccine, have remained the most appealing topics of interest among visitors over the years. The page that attracted more visitors over the six years was "real risks and benefits of vaccination", accounting for 5.67% of total sessions with a high mean duration spent of 05:08 minutes. CONCLUSION: During the six years of activity, overall, the level of users' engagement with the portal has dropped with an increased bounce rate and a lower average number of pages visited per session and a lower mean duration of each connection. The lowest engagement involved connections accessed through mobile devices. Results helped "Vaccinarsi" developers to speculate about future strategies to further increase the platform popularity and optimize visitors' engagement.

The role of the general practitioner in the screening and clinical management of chronic viral hepatitis in six EU countries.

INTRODUCTION: Chronic viral hepatitis is still a major public health concern in the EU. In order to halt the progression of the disease and to prevent onward transmission, timely recognition and accurate clinical management are crucial. The aim of the present study was to investigate the role of the general practitioner (GP) in the screening of persons at risk and in the clinical management of chronic viral hepatitis patients in six EU countries. METHODS: An online survey among GPs and secondary-care specialists was conducted in the UK, Germany, the Netherlands, Hungary, Italy and Spain. In the GP survey, we used a four-point Likert scale to find out how commonly risk groups are screened. In both surveys, we measured GPs involvement in monitoring clinical indicators in patients undergoing antiviral treatment, and explored whether patients in four clinical scenarios are referred back to primary care. RESULTS: Between five and 10 experts per professional group were surveyed, except for Spain (GPs: n = 2; Specialists: n = 4) and, in the case of the GP survey, Hungary (GPs: n = 1) and Germany (GPs: n = 4). Migrants are variably or not routinely screened for hepatitis B/C in the majority of cases. The majority of GPs reported that hepatitis B/C screening was routinely offered to people who inject drugs. In Hungary, Italy and in the Netherlands, screening sex workers is not a regular practice. As to whether GPs offer screening to men who have sex with men, responses varied; in Germany, the Netherlands and Italy, screening was "variably" or "commonly" implemented, while in Hungary the practice seems to be sporadic. In the UK, screening for hepatitis B seems to be common practice among GPs, while hepatitis C testing is only occasionally offered to this risk group. Most GPs (> 44%) in all countries except Hungary reported that hepatitis B/C screening was very commonly offered to HIV patients. The role of GPs in monitoring hepatitis cases and the referral of cases back to GPs by specialists varied both within and between countries. GPs are unlikely to monitor clinical outcomes other than side effects in patients undergoing treatment. Patients who have had a sustained virological response are usually referred back to GPs, whereas patients undergoing antiviral treatment and those who do not respond to treatment are rarely referred back. CONCLUSIONS: The GP's decision to offer screening to risk groups often seems to be an individual choice of the healthcare professional. Raising GPs' awareness of the disease, for example through the adoption of effective strategies for the dissemination and implementation of the existing guidelines for general practice, is strongly needed. The role of GPs and specialists involved in the management of chronically infected patients should also be clarified, as opinions sometimes differ markedly even within each professional group.

Pneumococcal vaccination: what have we learnt so far and what can we expect in the future?

Individuals <2 years and ≥ 50 years of age, as well as those with other specific risk factors, are especially vulnerable to invasive pneumococcal disease (IPD). Conjugate vaccines have been developed against encapsulated bacteria such as Streptococcus pneumoniae to provide improved immune responses. The 7-valent pneumococcal conjugate vaccine (PCV7) has significantly reduced the burden of vaccine-type pneumococcal diseases in children, including invasive disease and pneumonia and acute otitis media. There have also been significant declines in antimicrobial resistance in 7-valent vaccine serotypes and carriage of S. pneumoniae in the post-PCV7 era. Two to three years after the introduction of PCV13, there is emerging, global evidence of a reduced burden of pneumococcal diseases in children, including declines in IPD (UK and Germany) and nasopharyngeal carriage of PCV13 serotypes (Portugal and France). The functional immunogenicity of PCV13 in individuals ≥ 50 years of age has been demonstrated in clinical trials in comparison with the 23-valent pneumococcal polysaccharide vaccine and for children and adults 6 to 49 years of age. Between 2011 and 2013, PCV13 received market authorisation by the European Medicines Agency (EMA) for these additional age groups and is now available in Europe for the prevention of pneumococcal disease in all age groups.

Effect of myo-inositol and alpha-lipoic acid on oocyte quality in polycystic ovary syndrome non-obese women undergoing in vitro fertilization: a pilot study.

The aim of the present study was to evaluate the effectiveness of the combined administration of myo-inositol and α-lipoic acid in polycystic ovary syndrome (PCOS) patients with normal body mass index (BMI), who had previously undergone intracytoplasmic sperm injection (ICSI) and received myo-inositol alone. Thirty-six of 65 normal-weight patients affected by PCOS who did not achieve pregnancy and one patient who had a spontaneous abortion were re-enrolled and given a cycle of treatment with myo-inositol and α-lipoic acid. For all female partners of the treated couples, the endocrine-metabolic and ultrasound parameters, ovarian volume, oocyte and embryo quality, and pregnancy rates were assessed before and after three months of treatment and compared with those of previous in vitro fertilization (IVF) cycle(s). After supplementation of myo-inositol with α-lipoic acid, insulin levels, BMI and ovarian volume were significantly reduced compared with myo-inositol alone. No differences were found in the fertilization and cleavage rate or in the mean number of transferred embryos between the two different treatments, whereas the number of grade 1 embryos was significantly increased, with a significant reduction in the number of grade 2 embryos treated with myo-inositol plus α-lipoic acid. Clinical pregnancy was not significantly different with a trend for a higher percentage for of myo-inositol and α-lipoic acid compared to the myo-inositol alone group. Our preliminary data suggest that the supplementation of myo-inositol and α-lipoic acid in PCOS patients undergoing an IVF cycle can help to improve their reproductive outcome and also their metabolic profiles, opening potential for their use in long-term prevention of PCOS.

How can the results of Health Technology Assessment (HTA) evaluations applied to vaccinations be communicated to decision-makers and stakeholders? The ISPOR Rome Chapter Project.

HTA is considered the most comprehensive and transparent method of supporting decision-makers in their choices in Public Health. HTA on vaccines is being performed by many experts. However, they often present their studies to colleagues, but not to decisionmakers, who should be the main target and current users. It is therefore crucial to improve the transfer of scientific data to decision- makers and all stakeholders. The aims of the present project are: 1) to set up a team of experts to collect economic evaluations and HTA studies on vaccines and assess their actual use in decision-making processes; 2) to constitute regional working groups in order to identify the critical aspects of the communication process and identify the most appropriate method of data transfer. Systematic reviews of economic evaluations and HTA on vaccines and their actual use in decision-making will be used to draw up the basic documents for discussion by the 3 regional working boards. The working groups will discuss the current scientific evidence and communication methods and will try to implement a model of technology assessment with well-defined and objective criteria, in order to better fit pharmaco-economic and HTA methods to the field of vaccinations. Improving the transfer of HTA results to stakeholders, particularly decision-makers, will enable decisions to be taken on the basis of scientific evidence, and appropriate, sustainable actions to be undertaken.

Budget impact analysis of universal rotavirus vaccination in the Local Health Unit 11 Empoli, Tuscany, Italy.

BACKGROUND: Rotavirus (RV) infection is the first cause of acute viral gastroenteritis in children under five years of age all over the world; it mainly affects children between six and 24 months of age and can cause serious acute diarrhoea and dehydration. The aim of this study is to perform the budget impact analysis of universal rotavirus vaccination in the Local Health Unit (LHU) 11 Empoli, Tuscany, Italy. METHODS: An ad hoc mathematical simulation model was developed to evaluate the budget impact analysis of 5-years universal rotavirus vaccination. Particularly, incidence of rotavirus gastroenteritis (RVGE), hospitalizations, nosocomial diarrhoea, medical consultations, prescriptions and accesses to emergency department were taken into account in the analysis. The direct medical costs due to RV diarrhoea and the costs of vaccination campaign were considered as the main outcome measures in the study. RESULTS: The adoption of universal rotavirus vaccination campaign for five years in the LHU 11 Empoli would result in relevant savings due to the health cares avoided. These savings would overlapped the costs of vaccination yet from the second year after the introduction of vaccination. The saving for the Health Service would be 1.5 million Euro after five years of campaign. CONCLUSIONS: Universal vaccination against rotavirus results clinically and economically favourable for both the Health Service and the Society perspectives.

Surveillance of adverse events following immunization with meningococcal group C conjugate vaccine: Tuscany, 2005-2012.

INTRODUCTION: Post-licensure vaccine safety studies are essential to identify uncommon events that may be difficult to assess during pre-licensure studies. The aim of our study was to evaluate the safety of serogroup C meningococcal conjugate (MCC) vaccine in Tuscany from 2005 to 2012. METHODS: All adverse events (AEs) to MCC vaccine notified from 2005 to 2012 were obtained from the regional health authority. RESULTS: Following 451,570 doses administered, 110 suspected AEs were notified (mean annual reporting rate: 2.8/10,000 doses). The most frequently AE reported was fever (60%), followed by swelling at the injection site (11%) and febrile seizures (10%). Overall, 77.3% of cases were not severe, while 21.8% required hospitalization. Almost four months after the receipt of the vaccine, a one-year-old infant was diagnosed with a pervasive developmental disorder with disturbance of speech, but any link with the vaccinations received was refuted. Most AEs (80.9%) occurred after co-administration with other vaccines, especially with MMR or MMRV vaccines (42.7%) or the DTPa-HBV-IPV/Hib vaccine (33.7%). DISCUSSION: Our study confirmed the high level of safety of MCC vaccine in Tuscany: AEs proved rare and all cases had only temporary and self-resolving consequences. As usually only the most severe suspected AEs are reported, the true proportion of AEs requiring hospitalization was most probably overestimated, and it is plausible that most of these cases were in fact only temporally related.

[Improving vaccination social marketing by monitoring the web]. / Migliorare il marketing sociale in tema di vaccinazioni "presidiando" il Web.

Immunisation is one of the most important and cost- effective interventions in Public Health because of their significant positive impact on population health.However, since Jenner's discovery there always been a lively debate between supporters and opponents of vaccination; Today the antivaccination movement spreads its message mostly on the web, disseminating inaccurate data through blogs and forums, increasing vaccine rejection.In this context, the Società Italiana di Igiene (SItI) created a web project in order to fight the misinformation on the web regarding vaccinations, through a series of information tools, including scientific articles, educational information, video and multimedia presentations The web portal (http://www.vaccinarsi.org) was published in May 2013 and now is already available over one hundred web pages related to vaccinations Recently a Forum, a periodic newsletter and a Twitter page have been created. There has been an average of 10,000 hits per month. Currently our users are mostly healthcare professionals. The visibility of the site is very good and it currently ranks first in the Google's search engine, taping the word "vaccinarsi" The results of the first four months of activity are extremely encouraging and show the importance of this project; furthermore the application for quality certification by independent international Organizations has been submitted.

Present situation and new perspectives for vaccination against Neisseria meningitidis in Tuscany, Central Italy.

BACKGROUND: In Italy one third of bacterial meningitis are caused by Neisseria meningitidis. In March 2005, the Regional Health Authority of Tuscany included the meningococcal serogroup C conjugate (MCC) vaccine in the recommended vaccination program with a schedule of three doses to all newborns at 3, 5 and 13 months of age (from 2008 amended to a single dose at 13 months) and a single catch-up dose until age 6. OBJECTIVE: To evaluate the impact of the current national and regional immunization strategies against N. meningitidis and to highlight new perspectives for meningococcal disease prevention with the existing tetravalent meningococcal vaccine (ACWY) and with the future incoming meningococcal B vaccines. METHODS: Meningitis incidence rates in Italy and in Tuscany were calculated for the period 1994-2011 and 2005-2011,respectively. Immunization coverage with MCC vaccine in Tuscany and vaccination status of meningitis cases were reported. Literature review on meningococcal conjugate vaccine use and recommendation was performed. RESULTS: A decrease in incidence rates of meningococcal meningitis was observed in all age groups involved in the immunization campaign. Immunization coverage with MCC increased progressively year by year in Tuscany. A herd immunity effect was measured in unvaccinated age groups. Since 2006 no cases of invasive meningococcal C infection in vaccinated subjects were observed in Tuscany. CONCLUSIONS: Implementation of MCC vaccination in Tuscany was effective in preventing meningococcal C disease, confirming the effectiveness of the vaccine. A new tetravalent (ACWY) conjugate vaccine is now available and its use in all Italian Regions should be considered.

Sexual behavior, use of contraceptive methods and risk factors for HPV infections of students living in central Italy: implications for vaccination strategies.

The most frequent risk factors related to the infection/persistence of HPV in the population are an early start of sexual activity, the number of sexual partners, smoking, and the utilization of some contraceptive methods. In Italy, HPV vaccine is offered free of charge to all 12-year-old female adolescents, with a possible extension to other age groups according to Regional policies. In order to value the suitability of the current HPV vaccination strategies in Italy, an epidemiological study on sexual habits in adolescents and young adults was organized. An anonymous questionnaire on sexual behavior and risk factors for HPV infection was administered to 2300 students aged 13-24 years attending secondary schools and universities in Tuscany during 2008-09. About 12% of the sample declared to be foreign citizen. The results highlight the early start of sexual activity among young students. Particularly, more than half of the interviewed students declared to be already sexually active. The mean and the median age of the first sexual intercourse was 15.4 +/- 1.4 years and 15 years (25th and 75th percentiles = 14-16), respectively. More than 77% of students at age 16 years declared they already had the first sexual intercourse, compared with 0.3% of those <12 years. Generally, females aged 13-16-years, if sexually active, had sexual contacts with a single partner. Most students declared to know common contraceptive methods (male condom and contraceptive pill). However, only half of them declared a regular use of male condom. These data confirm the importance of vaccination against HPV for young females before their sexual debut. In addition, the current multi-cohort strategy of HPV vaccination in Tuscany (free of charge in the age range 12-16 years) allows also to catch up those girls that have not yet had their first sexual experiences before 16 years (21.5% according to our study) but also to those girls already sexually active, who very rarely are already infected by all vaccine types at 16 years. Our results also show the importance of sexual health education and of promotion of correct behaviours in schools.

[Mass communication during the "H1N1 flu"]. / La comunicazione di massa durante l'evento "influenza H1N1".

Nowadays communication plays a key role in healthcare, especially when a detailed risk analysis is important for correct information, as in the case of the H1N1 flu virus A. Through our study we have analyzed how the event "H1N1 flu" was addressed by the media, considering the period April 2009-June 2010. We collected the information from "Il Corriere della Sera", "La Repubblica" and "City", in addition to an online site for general information such as "TGCOM". The analyzed peak of daily news was seen a few weeks before the pandemic peak; in addition, after the peak of the pandemic, the interest of the press has completely collapsed, and eventually disappeared altogether. The media can influence the thought and consequentially how the recipients act, leading to a misperception of risk ('risk') and danger ('hazard'). Moreover the institutions and health professionals are not always able to communicate effectively to meet the needs for correct information. It is desirable in the future a greater degree of collaboration between media and authorities to have a clearer simpler and less misleading communication in the health field, helping recipients to act properly.

[Methodological aspects of clinical and economic impact of vaccine interventions and HTA. Focus on HPV vaccination]. / Aspetti metodologici della valutazione di impatto clinico ed economico negli interventi vaccinali in HTA. Focus sulla vaccinazione anti-HPV.

The aim of the present study is to analyze the methodological and technical aspects of Health Technology Assessment (HTA) as a tool for the clinical and economic impact of vaccine interventions, describe and comment the main studies at the national level, with a particular focus on HPV vaccination. The work was conducted in 3 phases: a) revision of the scientific literature, strictly linked to methodologies adopted in different studies on economic evaluations on HPV vaccines and analysis of Guidelines for building models for the economic assessment; b) analysis of the peculiarities and critical elements of economic evaluations in the field of vaccinology, from the clinical and epidemiological point of view, as well as the recognition of lack of knowledge on HPV infection dynamics; c) a comparative analysis of the two italian studies and of the results coming from them. Many differences between studies were found. Nevertheless, there is a general agreement on the economic profile of HPV vaccination for adolescent girls, if compared with the actual practice on the prevention of cervical carcinoma (pap-test screening). All the models showed a significant impact in terms of reduction of the incidence of cervical carcinoma and related mortality, in the long run, as well as a reduction of pre-cancer lesions and abnormal Pap tests. HTA approach has been recently recognized as a tool for decision making in vaccinology, and its methodologies and procedures are currently debated by public health experts. There is a strong need to continue the work in improving the model techniques of economic evaluations concerning HPV vaccination, as well as the adoption of homogeneous methods and standards, with the aim of helping the decision process in the field of Public Health.

The recommended lifetime immunization schedule from the board of vaccination calendar for life in Italy: A continuing example of impact on public health policies.

The Vaccination Calendar for Life is an alliance of scientific and professional societies of public health physicians, paediatricians and general practitioners in Italy which provides a periodical update on the ideal, scientifically driven vaccination calendar throughout lifetime. Since 2012, the Lifetime Immunization Schedule has represented a benchmark for Regional and National Authorities to set up the updated list of vaccines provided actively and free of charge to infants, children, adolescents, adults and the elderly by inclusion in the Triennial National Vaccination Plan (TNVP), and in the Essential Levels of Care (LEA). The impact of the different editions of the Lifetime Immunization Schedule on the TNVP was deep, representing the inspiring source for the present vaccination policy. The 2019 edition called for more attention to pregnant women immunization; risk groups vaccination; uniform high coverage with the MMRV vaccine; extension of Meningococcal B vaccination also at adolescent age; use of quadrivalent conjugate meningococcal vaccine also at 1 year of life; progressive decrease of the age of free-of-charge offer of influenza to ≥ 60 and then to ≥ 50 year-old population; implementation of flu immunization ages 6 months-6 years; HPV vaccination also offered to 25-year old women at the time of the first screening (gender neutral immunization already offered); sequential PCV13-PPV23 pneumococcal vaccination in 65 year-old subjects; increased coverage with rotavirus vaccine in infants and zoster vaccine in the elderly.

Maintain and increase vaccination coverage in children, adolescents, adults and elderly people: Let's avoid adding epidemics to the pandemic: Appeal from the Board of the Vaccination Calendar for Life in Italy: Maintain and increase coverage also by re-organizing vaccination services and reassuring the population.

The Board of the Vaccination Calendar for Life (Bonanni et al., 2014, 2017) [1,2]), a coalition of four major scientific and professional societies of public health physicians, pediatricians and general practitioners in Italy, made an appeal to health authorities in order to sustain vaccination in COVID-19 times. The five pillars to maintain and increase vaccination coverage at all ages are described as follows: 1) Guarantee paediatric vaccination coverage to all newborns and paediatric boosters and adolescent immunizations, not interrupting active calls and scheduled sessions. 2) Re-organise the way paediatric and adolescent vaccinations are offered. 3) Set-up recovery programs for vaccinations not carried out after the start of the COVID-19 emergency. 4) Provide the preparation of tenders for the supply of flu vaccines with suitable quantities to increase coverage in all Regions and Autonomous Provinces with extreme urgency. 5) Prepare plans to increase coverage for influenza, pneumococcal, tetanus diphtheria and shingles. The Board of the Calendar for Life appeals to the National and Local Health Authorities for a strong and coordinated commitment in favor of the widest offer and acceptance of vaccinations, whose vital importance for collective health is now even more evident to all, in order to avoid that delays in the necessary initiatives should add damage from other epidemics to those suffered by our population due to the COVID-19 pandemic.

Paediatric activities and adherence to vaccinations during the COVID-19 epidemic period in Tuscany, Italy: a survey of paediatricians.

INTRODUCTION: The global COVID-19 pandemic is placing a heavy burden on health services. One result could be a general reduction in routine vaccination activities. In Tuscany (Central Italy), paediatricians (in agreement with the regional health service) administer and register paediatric vaccinations of their patients. The aim of the present study was to evaluate the impact of the COVID-19 epidemic on paediatric vaccinations administered by Tuscan paediatricians, as a proxy of adherence to vaccinations during this epidemic period. METHODS: Four hundred members of the Tuscany section of the Italian Federation of Paediatricians (FIMP) were invited to participate in a semi-structured online survey. RESULTS: During the COVID-19 pandemic, almost all (98.2%) of the 223 respondents reported a general decline in outpatient paediatric visits; 65.8% reported a more than 60% reduction (144 answers) in comparison with the situation before the COVID-19 pandemic. A total of 208 paediatricians (93.3%) continued to vaccinate in the period considered: 66/208 (31.7%) reported a reduction in parents' compliance with mandatory vaccination (hexavalent and MMRV vaccines), and 88/208 (42.3%) reported a reduction in compliance with non-mandatory vaccinations. Almost all paediatricians declared having taken preventive actions to counter the spread of SARS-CoV-2. DISCUSSION AND CONCLUSIONS: Although the majority of Tuscan paediatricians continued to vaccinate during the lock-down, some parents decided to postpone their children's scheduled vaccinations, mainly owing to fears concerning the safety of access to health services. When Italian immunization coverage data on the first months of 2020 become available, it will be possible to assess the real impact of the COVID-19 pandemic on paediatric vaccinations. It is crucial to continue vaccinating against preventable infectious diseases in order to avoid other possible epidemic outbreaks. The pandemic must not be seen as an obstacle to compliance with the vaccination schedule, but rather as an excellent opportunity to underline the importance of all recommended vaccinations.

Invasive meningococcal disease in Italy: from analysis of national data to an evidence-based vaccination strategy.

INTRODUCTION: Invasive meningococcal disease (IMD) is one of the most severe vaccine-preventable disease not yet under control. In Italy, although different anti-meningococcal vaccines are available, their offer among regions is heterogeneous. The aim of this study is to describe the epidemiology of IMD in Italy based on analysis of national surveillance data for 2011-2017 to optimize the vaccination strategy. METHODS: IMD surveillance data from the Italian National Health Institute were analysed. Microsoft Excel was used to present trend analysis, stratifying by age and serogroups. RESULTS: In Italy, during the period 2011-2017, the incidence of IMD increased from 0.25 cases/100,000 inhabitants in 2011 to 0.33 cases/100,000 in 2017. Most cases after 2012 were caused by non-B serogroups. The number of cases in subjects aged 25-64 years increased steadily after 2012 (36 cases in 2011, 79 in 2017), mostly due to non-B serogroups, representing more than 65% of cases in those aged 25+ years. CONCLUSIONS: In the period from 2011 to 2017, the incidence of IMDs increased in Italy. The increase, probably due also to a better surveillance, highlights the importance of the disease in the adult population and the high level of circulation of non-B serogroups in particular after 2012. Our analysis supports an anti-meningococcal vaccination plan in Italy that should include the highest number of preventable serogroups and be aimed at vaccinating a wider population through a multicohort strategy.

A validation study of the clinical diagnosis of Dup15q syndrome: Which symptoms matter most?

PURPOSE: Dup15q syndrome is a rare genetic disease with a fairly nonspecific phenotype, clinical heterogeneity, and a wide spectrum of severity. However, no formal characterization has been attempted to select clusters of symptoms, signs and instrumental tests, to be used in the differential diagnosis with other neurodevelopmental disorders. Thus, our purpose was to identify symptoms, signs and instrumental findings, singly or in various combinations, favoring the early diagnosis of the Dup15q syndrome and the indication for genetic testing. METHODS: 25 patients with Dup15q syndrome and 25 age and sex matched controls with other neurodevelopmental disorders were the study population. Patients' history, clinical and instrumental assessment were examined by five expert child neurologists blind to the genetic diagnosis. Each rater was asked to make the diagnosis in three subsequent steps: 1. Revision of the medical records; 2. Examination of the videorecorded clinical findings; 3. Assessment of the instrumental tests. Inter-rater agreement was measured with the Kendall's coefficient of concordance) and the Kappa statistic. Sensitivity, specificity and predictive values for symptoms, signs and instrumental findings, singly or in various combinations, were measured. RESULTS: The Kendall's coefficient for the diagnosis of Dup15q syndrome was 0.43 at step 1 was 0.43, at step 2 was 0.42, at step 3. Patients with past feeding difficulties, hypotonia during the neonatal period, and epilepsy had >80 % probability of having the Dup15q syndrome. CONCLUSION: Feeding difficulties, hypotonia and epilepsy, though unspecific, can be used as signals of Dup15q syndrome and focused search of genetic abnormalities.
