Type 1 diabetes and the gut: characterization of intestinal environment in Non-Obese Diabetic mice at different disease stages

Type 1 diabetes, previously defined as insulin-dependent or juvenile-onset diabetes, is a chronic autoimmune disease characterized by cellular-mediated destruction of the β-cells of the pancreas, leading to absolute insulin deficiency and consequently an aberrant glucose homeostasis. Over the past fifty years a global pandemic of TD1 has been registered and the incidence of the disease in Europe is expected to double in the next decade. The global increase in the disease rate cannot be explained only by genetic alterations or improved diagnostic tools, and thus it was postulated that environmental factors are likely to be involved in this global trend. The intestinal environment, especially its resident flora and its associated immune system have been implicated in the pathogenesis of the disease. The present study aims to characterize the intestinal environment in the most widely used model of the disease, the non-obese diabetic mouse. The gut microbiota, gut permeability and gut immune system will be assessed in four population of mice: three-week old mice, eight-week old mice, mice with recent onset of the disease and long term non progressor mice. This characterization should allow us to understand if any of the variables studied varies in an age dependent manner and is correlated or can predict the onset of the disease in the animal model

Risk of transmission of vaccine-preventable diseases in healthcare settings

: The transmission of infectious agents within healthcare settings is a priority public health problem. Although the main burden of healthcare-associated infections is commonly caused by Gram-negative bacteria and fungi, vaccine-preventable diseases represent an additional infectious risk for patients attending healthcare facilities. Hepatitis B, rotavirus gastroenteritis, influenza, measles, pertussis and pneumococcal and meningococcal invasive bacterial infections still represent a threat, notwithstanding the presence of universal vaccination programs. For this reason, healthcare worker immunization is an important strategy to limit the risk of vaccine-preventable diseases in such a fragile population

Legitimising a ‘zombie idea’: childhood vaccines and autism – the complex tale of two judgments on vaccine injury in Italy

The impact of 'bad' science on judicial decision-making is a thorny aspect of the relationship between science and law. This study employs doctrinal and empirical analysis to explore two Italian judgments that asserted a causal link between childhood vaccines and autism. Using a combination of actor-network theory and legal pragmatism, we uncovered a network of actors and institutions internal and external to the legal system enabling these impactful decisions that went on to contribute to a crisis in vaccination coverage in Italy. These include trial strategies, resources, communication practices between arms of government, awareness and responsiveness of institutional actors, and institutional mechanisms governing the integration of scientific expertise into the legal process. By forensically analysing how a 'zombie idea' received a patent of legitimacy in the Italian context, this study provides useful lessons for legal systems grappling with complex and contested public health matters

Inaction, under-reaction action and incapacity:communication breakdown in Italy’s vaccination governance

This article explores why governments do not respond to public compliance problems in a timely manner with appropriate instruments, and the consequences of their failure to do so. Utilising a case study of Italian vaccination policy, the article considers counterfactuals and the challenges of governing health policy in an age of disinformation. It counterposes two methods of governing vaccination compliance: discipline, which uses public institutions to inculcate the population with favourable attitudes and practices, and modulation, which uses access to public institutions as a form of control. The Italian government ineffectively employed discipline for a number of years. Epistemological and organisational constraints stymied its efforts to tackle a significant childhood vaccination compliance problem. With a loss of control over the information environment, vaccinations were not served well by exogenous crises, the sensationalism of the news cycle and online misinformation. Hampered by austerity, lack of capacity and epistemic shortcomings, the Italian government did not protect the public legitimacy of the vaccination programme. Instead of employing communications to reassure a hesitant population, they focused on systemic and delivery issues, until it was too late to do anything except make vaccinations mandatory (using modulation). The apparent short-term success of this measure in generating population compliance does not foreclose the need for ongoing governance of vaccine confidence through effective discipline. This is evident for the COVID-19 vaccination campaign, with many Italians still indicating that they would not accept a vaccine despite the devastation that the disease has wrought throughout their country

[Policy changes introduced by the national vaccine prevention plan and the mandatory vaccination law of 2017: opinions and attitudes of Italian healthcare workers]

: The Italian National Vaccine Prevention Plan (PNPV) of 2017-19 and subsequent mandatory vaccination law (Law 119/2017) both occurred in the context of a progressive decrease in vaccine coverage levels in Italy and led to important policy changes, including the introduction of new vaccine recommendations and increasing the number of mandatory vaccinations in childhood from four to ten. A survey on a sample of 446 Italian health care workers (HCW) was carried out in order to assess their opinions on policy changes introduced by the PNPV and by the mandatory vaccination law. The convenience sample was selected among participants in a training course on vaccination counselling. The large majority of participants expressed overall satisfaction about the policy changes introduced by the PNPV but some highlighted pitfalls related to its implementation. Moreover, the majority of HCW believe that vaccination coverage for both recommended and mandatory vaccinations has increased thanks to Law 119/2017, therefore expressing a positive attitude towards the enforcement of vaccine mandates

Role of the National Immunisation Technical Advisory Groups in 13 European countries in the decision-making process on vaccine recommendations

: In Europe, National Immunisation Technical Advisory Groups (NITAGs) were established in most countries to promote evidence-informed decision-making in introducing new or improved vaccines or changing recommendations for existing ones. Still, the role, activities and outcomes of NITAGs have not been optimally implemented across Europe. Within the European Joint Action on Vaccination (EU-JAV), we conducted a survey to collect information on decision-making process including the main criteria for the introduction of new vaccines or changes to recommendations on their use. Between December 2021 and January 2022, 13 of the 28 European countries invited participated in an online survey. The criteria ranked as most relevant were disease burden and availability of financial resources. Only one country specified that the NITAG recommendations were binding for the government or the health authority. Vaccinations more often reported for introduction or recommendation changes were those against herpes zoster, influenza, human papillomavirus infection, pneumococcal and meningococcal disease. The planned changes will mainly address children and adolescents (2-18 years) and adults (≥ 45-65 years). Our findings show potential overlaps in the activities of NITAGs between countries; and therefore, collaboration between NITAGs may lead to optimisation of the workload and better use of resources

Invasive Pneumococcal Disease in Tuscany Region, Italy, 2016–2017: Integrating Multiple Data Sources to Investigate Underreporting

: Invasive pneumococcal disease (IPD) is a vaccine-preventable disease characterized by the presence of Streptococcus pneumoniae in normally sterile sites. Since 2007, Italy has implemented an IPD national surveillance system (IPD-NSS). This system suffers from high rates of underreporting. To estimate the level of underreporting of IPD in 2016-2017 in Tuscany (Italy), we integrated data from IPD-NSS and two other regional data sources, i.e., Tuscany regional microbiological surveillance (Microbiological Surveillance and Antibiotic Resistance in Tuscany, SMART) and hospitalization discharge records (HDRs). We collected (1) notifications to IPD-NSS, (2) SMART records positive for S. pneumoniae from normally sterile sites, and (3) hospitalization records with IPD-related International Classification of Diseases, Ninth Revision, Clinical Modification (ICD9) codes in discharge diagnoses. We performed data linkage of the three sources to obtain a combined surveillance system (CSS). Using the CSS, we calculated the completeness of the three sources and performed a three-source log-linear capture-recapture analysis to estimate total IPD underreporting. In total, 127 IPD cases were identified from IPD-NSS, 320 were identified from SMART, and 658 were identified from HDRs. After data linkage, a total of 904 unique cases were detected. The average yearly CSS notification rate was 12.1/100,000 inhabitants. Completeness was 14.0% for IPD-NSS, 35.4% for SMART, and 72.8% for HDRs. The capture-recapture analysis suggested a total estimate of 3419 cases of IPD (95% confidence interval (CI): 1364-5474), corresponding to an underreporting rate of 73.7% (95% CI: 34.0-83.6) for CSS. This study shows substantial underreporting in the Tuscany IPD surveillance system. Integration of available data sources may be a useful approach to complement notification-based surveillance and provide decision-makers with better information to plan effective control strategies against IPD

Knowledge of public health informatics among Italian medical residents: design and preliminary validation of a questionnaire

Background: public health requires strong information skills and competencies, as it is information-intensive and information-driven. Public health informatics has been defined as the “systematic application of information, computer science, and technology to public health practice, research, and learning”. New information and communication technologies offer unprecedented opportunities, such as linking smart-phones and mobiles devices to web based tools for data collection, enabling and enhancing participatory epidemiology. However, being an emerging discipline, despite its potential and importance, public health informatics is often neglected and overlooked, being rarely offered as course. The present study was designed as a pilot study, with the aim of designing and validating a questionnaire on the knowledge of public health informatics among medical residents in public health in Italy.  Methods and Results: thirty-two Italian residents in public health volunteered to take part into the study. Mean age of the sample was 31.44±2.23 years, most responders were males (68.8%), from northern Italy (53.1%), at the third year of residency (34.4%) and currently doing practical training at the clinical management staff/hospital directorate (34.4%). Other places of training were the Prevention Department (21.9%), the Institute of Hygiene (18.8%), the local health units and the territory (12.5%), the occupational health service (6.3%) and the Regional Health Agency (3.1%). Cronbach’s alpha coefficient yielded a value of 0.909, demonstrating excellent psychometric properties of the instrument.  Conclusion: in conclusion, the developed questionnaire seems to be an appropriate and useful tool to detect gaps concerning knowledge, education and practices of public health informatics among residents in public health.&nbsp
