Background: Tick-borne encephalitis (TBE) is a severe viral infection of the central nervous system transmitted by tick bites. Vaccination represents the only effective preventive measure, yet data on TBE vaccine effectiveness in Italy are lacking. This study aimed to evaluate TBE vaccine effectiveness and vaccination coverage in the province of Udine, an endemic area in the Friuli Venezia Giulia region of Northern Italy. Methods: We conducted a case–control study using linked anonymized health databases of the region, including vaccination, laboratory, and hospital admission records from 2017 to 2025. Cases were defined as residents hospitalized with a diagnosis of TBE (ICD-9-CM 063.x or 321.2) and a positive anti-TBE IgM result in serum or cerebrospinal fluid. Controls were residents tested for anti-TBE IgM during the same period but not hospitalized for TBE. Vaccination history was retrieved from the regional vaccination registry. Vaccine effectiveness was estimated through logistic regression models comparing vaccinated and unvaccinated individuals. Results: Between 2017 and 2025, 21 confirmed TBE hospitalizations were recorded (mean annual incidence: 0.45/100,000 inhabitants). The mean hospital stay was 13.8. Among 6065 individuals tested for anti-TBE IgM, 95.2% of cases and 81.8% of controls were unvaccinated. The estimated odds ratio of TBE hospitalization for individuals with ≥3 vaccine doses versus unvaccinated was 0.11 (95% CI: 0.02–0.88). Vaccination coverage in 2025 reached about 10% of the provincial population, with markedly higher coverage (up to 34%) in mountain districts compared with lowland areas (<5%). Conclusions: Although limited by small sample size, this study provides the first real-world evidence of TBE vaccine effectiveness in an Italian endemic area. Vaccination is an effective preventive measure. Given the regional epidemiology and expected increase in tick activity due to climate change, strengthening vaccination uptake and public awareness in endemic districts is strongly recommended.

Background: Mercury is a neurotoxin, and limited prenatal exposure to it can affect long-term child neurodevelopment. However, results of epidemiologic studies of such exposure have been inconsistent. We examined the association of prenatal mercury exposure from maternal fish consumption with child neurodevelopment in northern Italy. Methods: A population-based cohort of 606 children and their mothers was studied from pregnancy to age 18 months. Mercury levels were measured in maternal hair and blood during pregnancy and in umbilical cord blood and breast milk. Levels of polyunsaturated fatty acids (PUFAs) were measured in maternal serum. Maternal and child intakes of fish were assessed by using a food frequency questionnaire. The Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III) was used to evaluate child neurodevelopment. Multivariate linear regression was used to examine the association of mercury exposure with BSID-III scores, after controlling for maternal fish intake, PUFAs during pregnancy, and several other confounders. Results: Mean weekly fish intake during pregnancy was less than 2 servings. Mercury concentrations in biological samples were low (mean, 1061 ng/g in hair) and moderately correlated with fish intake, particularly of carnivorous species. Maternal ω-3 PUFA concentrations were poorly correlated with fish intake. Maternal intelligence quotient (IQ) and child intake of fish were significantly associated with neurodevelopment scores. In multivariate models, the level of Hg exposure was not associated with neurodevelopmental performance at 18 months. Conclusions: In this Italian population, neurodevelopment at 18 months was associated with child intake of fresh fish and maternal IQ rather than with mercury exposure. The expected beneficial effect of maternal fish intake (from maternal ω-3 PUFAs) was not found. [PUBLICATION ABSTRACT]

The association between diabetes mellitus and the occurrence of digestive organs cancers was investigated in the Italian region Friuli Venezia Giulia. The risk of cancer associated with oral antidiabetic drugs among subjects with type 2 diabetes was also assessed. This was a retrospective population-based cohort study based on the 2002–2014 regional administrative health data. Incident digestive cancers were identified through the hospital discharge diagnoses. The incidence rates of cancer at different sites were calculated for type 1 and 2 diabetics and for non-diabetics. Proportional hazard models were built to assess the risk of cancer associated with diabetes and antidiabetic drugs. Diabetes was associated with increased risk of digestive cancers. Liver and pancreatic cancers were associated with the highest hazard ratios. Among type 2 diabetics, total number of metformin prescriptions was associated with reduced risk of most types of digestive cancers; sulfonylureas with reduced risk of stomach and pancreatic cancer. In this Italian population the excess risk of digestive cancers for diabetic patients was confirmed. Further research is needed to clarify the role of antidiabetic drugs.

Introduction Type 2 diabetes mellitus (T2DM) is a non-communicable disease representing one of the most serious public health challenges of the twenty-first century. Its incidence continues to rise in both developed and developing countries, causing the death of 1.5 million people every year. The use of technology (e.g. smartphone application—App) in the health field has progressively increased as it has been proved to be effective in helping individuals manage their long-term diseases. Therefore, it has the potential to reduce the use of health service and its related costs. The objective of this study is to evaluate the impact of using a digital platform called “TreC Diabete” embedded into a novel organisational asset targeting poorly controlled T2DM individuals in the Autonomous Province of Trento (PAT), Italy. Methods This trial was designed as a multi-centre, open-label, randomised, superiority study with two parallel groups and a 1:1 allocation ratio. Individuals regularly attending outpatient diabetes clinics, providing informed consent, are randomised to be prescribed TreC Diabete platform as part of their personalised care plan. Healthcare staff members will remotely assess the data shared by the participants through the App by using a dedicated online medical dashboard. The primary end-point is the evaluation of the Hb1Ac level at 12-month post-randomisation. Data will be analysed on an intention-to-treat (ITT) basis. Discussion This trial is the first conducted in the PAT area for the use of an App specifically designed for individuals with poorly controlled T2DM. If the effects of introducing this specific App within a new organisational asset are positive, the digital platform will represent a possible way for people diagnosed with T2DM to better manage their health in the future. Results will be disseminated through conferences and peer-reviewed journals once the study is completed. Trial registration ClinicalTrials.gov NCT05629221. Registered on November 29, 2022, prior start of inclusion.

The objective of this study was to assess complexity of patients discharged from hospital to intermediate care facility in an Italian setting. Multiple anonymous health-related databases were linked at the individual patient level through a stochastic key to study patients discharged from the University Hospital of Udine, Italy, from 2010 to 2019. Patient complexity was measured through diagnosis related group (DRG) relative weight of each hospitalization, number of chronic conditions and annual use of health resources. 12,674 intermediate care facility admissions were recorded in the study period. Mean DRG weight was 1.54±1.05 with variations depending on the discharging hospital ward. Patients discharged to intermediate facilities had higher DRG weight, had more comorbidities and consumed more health resources than the others, particularly in case of patients discharged from surgical wards. Patients discharged to intermediate care facilities are particularly complex, have high use of health resources, and may be difficult to manage.

There is limited information regarding the severity of COVID-19 in immunocompromized patients. We conducted a retrospective cohort study considering the period from 1 March 2020 to 31 December 2020 to determine whether previously existing lymphopenia increases the risk of hospitalization and death after SARS-CoV-2 infection in the general population. The laboratory and hospital discharge databases of the Azienda Sanitaria Universitaria Friuli Centrale were used, and 5415 subjects infected with SARS-CoV-2 and with at least one recent absolute lymphocyte count determination before SARS-CoV-2 positivity were included. In total, 817 (15.1%) patients had severe COVID-19. Patients developing severe COVID-19 were more frequently males (44.9% of the severe COVID-19 group vs. 41.5% in the non-severe COVID-19 group; p < 0.0001) and were older (73.2 ± 13.8 vs. 58.4 ± 20.3 years; p < 0.0001). Furthermore, 29.9% of the lymphopenic patients developed severe COVID-19 vs. 14.5% of the non-lymphopenic patients (p < 0.0001). In a logistic regression model, female sex remained a protective factor (OR = 0.514, 95%CI 0.438–0.602, p < 0.0001), while age and lymphopenia remained risk factors for severe COVID-19 (OR = 1.047, 95%CI 1.042–1.053, p < 0.0001 for each additional year of age; OR = 1.715, 95%CI 1.239–2.347, p = 0.0011 for lymphopenia). This provides further information to stratify the risk of COVID-19 severity, which may be an important element in the management of immunosuppressive therapies.

ObjectiveThe objectives of this study were to estimate influenza vaccination coverage among patients with diabetes mellitus in an Italian 250 000-inhabitant area in the 2017–2018 season and to assess whether glycaemic control and pharmacological treatment were associated with the likelihood of being vaccinated.DesignIn this cross-sectional study, we analysed anonymous health administrative databases, linked with each other at the individual patient level through a stochastic key: diabetes mellitus registry, vaccinations, drug prescriptions and laboratory database.SettingThe study was conducted in the catchment area of the University Hospital of Udine (‘the Udine area’), a 250 000-inhabitant area in the northeast of Italy.ParticipantsThe study included all subjects included in the regional registry of patients with diabetes mellitus, living in the Udine area as of 1 October 2017.Main outcome measuresVaccination coverage in the 2017–2018 influenza season was calculated. The association between patients’ characteristics and the likelihood of being vaccinated was assessed through multivariate log binomial regression.Result53.0% of 15 900 patients with diabetes living in the area were vaccinated. Coverage increased with age, approaching 75% at ≥85 years. Patients lacking recent glycated haemoglobin testing were less likely to be vaccinated (43.4% vaccination coverage), as were those not treated pharmacologically (44.4% vaccination coverage). Patients treated with both insulin, metformin and other antidiabetic medications were more likely to be vaccinated than those treated with metformin alone (58.1% vaccination coverage; adjusted relative risk=1.07, 95% CI 1.01 to 1.14).ConclusionInfluenza vaccination coverage was suboptimal in this Italian population of patients with diabetes. Strategies to improve diabetes management could in turn positively affect influenza coverage.

IntroductionPrenatal alcohol exposure (PAE) is a well-established risk factor for adverse neurodevelopmental outcomes, particularly at high levels of consumption. The impact of low-to-moderate PAE remains unclear, with mixed results reported. This study investigates the effects of low-level PAE on neurodevelopmental outcomes at 18 months in Italian mother-child pairs enrolled in the Italian Northern Adriatic Cohort II, a part of the ‘Public health impact of long-term, low-level, mixed element exposure in susceptible population strata’ project PHIME.MethodsThe study population consisted of 632 children, and their mothers, who were tested with the Bayley Scales of Infant and Toddler Development third edition (BSID-III) at 18 months of age. PAE, socio-demographic and lifestyle information was collected through questionnaires at different phases of follow-up. We analysed 605 children born at term (≥37 weeks) with BSID-III data and maternal pregnancy alcohol intake estimates. Multiple linear regression assessed associations between each BSID-III composite score (cognitive, motor, language) and PAE.ResultsMothers’ alcohol consumption was very low. The median (25th percentile to 75th percentile) of the weekly alcohol intake of the 605 mothers was 0.3 (0–1.4) drinks and of the children’s cognitive, language and motor composite score were 105 (100–110), 97 (91–103) and 100 (97–107), respectively. No significant association was found between maternal alcohol intake and BSID-III cognitive nor language scores. Only a suggestive, non-consistent, inverse association was found between PAE and motor neurodevelopment. Maternal IQ and promotion of child autonomy were directly associated with all neurodevelopmental outcomes.ConclusionLow levels of PAE were not associated with neurodevelopmental impairment at 18 months, except for possible motor impairment at higher exposures: our findings highlight the predominant influence of maternal IQ and the home environment. Further research, including a broader range of alcohol exposure, is needed to better define potential safety thresholds of PAE on early-life neurodevelopment.

Background/Objectives: HPV is the most common sexually transmitted infectious agent worldwide and adolescents are at high risk of contracting HPV. The aim of our study was to find out how much adolescents know about the virus and its effects, and to obtain information on attitudes and behaviors regarding HPV vaccination to close these gaps. Methods: As part of the ESPRIT project, 598 lower secondary (11–14 years) and upper secondary (14–19 years) school students from three Italian regions were surveyed between December 2023 and March 2024 using a seven-question online questionnaire on awareness, knowledge, and attitudes about HPV and the HPV vaccine. Count and zero-inflation models were used to determine correlations between sexes, urban/suburban, province of residence, and school type with knowledge. Results: Lower secondary students believed that HPV causes HIV/AIDS (8.9%) or hepatitis C (3.0%) and rarely mentioned anal (21%) and oral sex (9.6%) as ways of transmission. Among upper secondary students, misconceptions were similar, with worrying rates of students stating that HPV only causes cancer in females (18%) or males (2.4%), and low rates of identifying transmission risk through anal (41%) and oral (34%) sex and genital contact (38%). The HPV vaccination rate was quite low (47% in lower secondary students, 61% in upper secondary students). In the regressions, sex, urban/suburban area, and province were the variables associated with higher levels of knowledge for lower secondary students; for upper secondary students, level of knowledge was associated with sex, urban/suburban area, school type, and province of residence. Conclusions: Awareness and knowledge of HPV and the HPV vaccine are low among Italian students in this study and reported vaccination coverage is below the national target. Coordinated efforts at the national level are needed to address this public health issue.

Background: Mercury is a neurotoxic environmental pollutant. However, the literature on the neurodevelopmental effect of low-level prenatal mercury exposure from maternal fish intake is inconsistent. We assessed the association between prenatal mercury exposure and infant neurodevelopment in coastal areas of 4 Mediterranean countries. Methods: This was a prospective cohort study that planned to enroll approximately 1700 mother-infant pairs. Pregnant women and their newborn children were recruited in selected hospitals of the study areas. Biological samples, including maternal hair and cord blood, were collected from mothers and children, and the concentrations of mercury and other elements were measured. Exposures to lifestyle, environmental, and social factors were assessed through questionnaires. The main outcome was child neurodevelopment at 18 months, as measured by the Bayley Scales of Infant and Toddler Development, Third Edition. Conclusions: This cohort has a number of strengths. First, mercury concentration was measured in several biological samples, which allows for a better understanding of mercury kinetics and is useful for sensitivity analyses. Therefore, we expect to be able to adjust for the potential confounding effects of lifestyle and social factors and for the effects of other elements that were measured in the biological samples. Finally, this is a multinational study and thus permits assessment of the relation between mercury and child neurodevelopment in different populations. [PUBLICATION ABSTRACT]
