RESUMEN
Introduction: In Italy, over 4.8 million individuals aged 0-19 years have been infected with SARS-CoV-2. This study aims to evaluate the spread of SARS-CoV-2 within schools in Modena province and the influence of anti-SARS-CoV-2 vaccination coverage. Methods: We performed a survey in the period 1 September-15 December 2021, involving student population aged 0-19 years and related teachers screened for SARS-CoV-2 infection using nasopharyngeal swab after the detection of an index case within their class. During the study period, vaccination against SARS-CoV-2 was actively offered to all subjects aged ≥12 years. Results: A total of 13,934 subjects were tested, 12,534 students and 1,400 teachers (594 classes). We identified a total of 594 and 779 index and secondary cases, respectively. We found that 9.8% of students and 10.6% of teachers were positive for SARS-CoV-2. Overall at the test time, 32.5% were vaccinated with at least one dose of anti-SARS-CoV-2 vaccine. Among secondary cases, 7.8% were vaccinated compared to 34.9% among negative tested subjects. A higher secondary attack rate was for non-vaccinated subjects rather than vaccinated ones (8.1% vs. 1.4%). Higher secondary attack rates were reported for subjects attending infant and primary school (5.9 and 9.6%, respectively). Lower secondary attack rates were for those who attended middle school (4.9%) and especially high school (1.7%). Conclusion: Our results highlight the differential spread of the infection within various educational settings and that the vaccination, available in the study period for the population aged ≥12, have mitigated SARS-CoV-2 spread in high and middle schools.

BACKGROUND: Currently, Italian versions of the Hypoglycemia Fear Survey for Children (CHFS) and for Parents (PHFS) quantifying Fear of Hypoglycemia (FoH) in pediatric diabetes are not available. OBJECTIVE: To validate the Italian version of the CHFS and PHFS. SUBJECTS AND METHODS: One hundred and seventy-four children with type 1 diabetes aged 6-18 and 178 parents completed the CHFS and PHFS, the PedsQL 3.0 Diabetes module and the KIDSCREEN-10. Internal consistency was good (α = 0.85 for CHFS, α = 0.88 for PHFS); validity was supported by correlations of CHFS total score (CHFS-T r = -0.50; p < 0.001, CI = -0.62 to -0.35) and Worry subscale (CHFS-W r = -0.49; p < 0.001, CI = -0.62 to -0.32) with measures of health-related quality of life (QoL), which were not related to PHFS scores. Factor analyses justified the structure and the separate scoring of Behavior and Worry subscales. Children's age was negatively correlated with CHFS-T (r = -0.16; p = 0.03, CI = -0.36 to 0.00), CHFS-W (r = -0.29; p = 0.02, CI = -0.39 to -0.07), PHFS-T (r = -0.20; p = 0.006, CI = -0.35 to -0.04), PHFS-B (r = -0.30; p = 0.001, CI = -0.43 to -0.17). Mean (SD) item scores of CHFS-T (1.47 ± 0.56 vs. 1.27 ± 0.57; p < 0.05) and CHFS-W (1.20 ± 0.73 vs. 0.96 ± 0.68; p < 0.05) were higher in children with HbA1c ≥7.5%. Higher levels of distress for upsetting hypoglycemia were associated with lower child's QoL scores as perceived by children (Peds-QL: 72.6 ± 12.8 vs. 80.4 ± 11.9; p < 0.001) and parents (Peds-QL: 70.6 ± 13.8 vs. 75.8 ± 12.9; p < 0.05). CONCLUSION: The Italian version of CHFS and PHFS appears to be a valid measure to assess FoH in clinical practice and factor analysis supports separate scoring for the Worry and Behavior subscales.

BACKGROUND AND AIM: In early 2020, SARS-CoV-2 was declared a pandemic by the WHO and Italy was one of the first and most severely affected country in Europe. Despite the global interest about COVID-19 pandemic, several aspects of this infection are still unclear, especially in pediatric population. This study aims to investigate the characteristics of the isolated or quarantined children and adolescents followed by the Public Health Department of the Italian province of Modena during the first wave of COVID-19. METHODS: The study population included all non-adult subjects aged 0-18 years who underwent isolation or quarantine during the first wave of SARS-CoV-2 pandemic from February 24 to June 18, 2020 in Modena province, Northern Italy. RESULTS: In Modena province, 1230 children and adolescents were isolated in case of SARS-CoV-2 infection (6.3%), or quarantined due to close contact with confirmed cases (88.7%) or travelling from a high-risk area (5.0%). Among 349 individuals who underwent swab testing, 294 (84.2%) reported close contact with an infected cohabiting relative and 158 (45.3%) were symptomatic. Among all tested subjects, 78 (22.4%) resulted positive, with a higher proportion of symptomatic subjects compared with the SARS-CoV-2-negative (78.2% vs. 35.8%). Fever was mostly present in SARS-CoV-2-positive children (48.7% vs. 12.6%). Both anosmia (58.3% vs. 41.7%) and dysgeusia (54.5% vs. 45.5%) had only slightly higher frequency in SARS-CoV-2-positive. CONCLUSIONS: These findings allow to expand the knowledge regarding characteristics of non-adult subjects isolated or quarantined during the first wave of SARS-CoV-2 pandemic. (www.actabiomedica.it).

BACKGROUND: No data exist about the changes induced by the transition from first-generation long-acting insulins to second-generation long-acting analogues in the paediatric population. OBJECTIVE: To assess changes in insulin/carbohydrate ratio (I:CHO) after the first 6 months of degludec therapy in a paediatric population with type 1 diabetes previously treated with glargine U100. SUBJECTS: All patients treated with degludec under routine clinical practice conditions were retrospectively analysed. METHODS: Nonprofit observational retrospective study. Changes during the follow-up in mean CHO/I ratio were assessed using longitudinal linear models for repeated measures. Rate of hypoglycaemia, ketoacidosis and adverse events was evaluated. RESULTS: Overall, 51 children (mean age 13.8 ± 4.6 years; mean diabetes duration 5.8 ± 3.9 years) started therapy with degludec in the period between April 2017 and April 2018. I:CHO ratio before starting degludec therapy significantly differed among the three meals, being the lowest at breakfast and the highest at dinner. After introducing degludec, I:CHO ratio at lunch (-1.29 95% CI -2.02;-0.57) and at dinner (-3.08 95% CI -4.35;-1.8) significantly decreased, while it slightly increased at breakfast (+1.37 95% CI 0.47;2.28). No episodes of severe hypoglycaemia, ketoacidosis and adverse event were recorded during 6 months. CONCLUSIONS: Our data show that the use of degludec is associated with a significant change in the I:CHO ratio at the different meals compared to the previous glargine therapy. This could derive from the flat and prolonged pharmacokinetic profile of degludec. This has important clinical implications for daily insulin dose adjustments.
RESUMEN
Outcomes of insulin analogues in pediatric diabetes camps are poorly investigated; no data is available about insulin degludec (IDeg).Our aim was to assess impact of insulin therapy adopted by the participants to a 4-day diabetes camp held in 2017, hypothesizing a possible excess risk of hypoglycemia in patients treated with IDeg. Overall, 40 children with type 1 diabetes (mean age 13.4±3.0 years; 62.5% males) attended the camp (20.0% on continuous subcutaneous insulin infusion and 80.0% on multiple daily injections - MDI). Among children in MDI regimen, 71.9% were treated with IDeg as basal insulin and 28.1% with glargine U100 (IGlar). All patients used Lispro or Aspart as short-acting insulin. Daily plan of the camp included educational sessions, physical exercise, 3 main meals and 2 snacks. At the arrival, IGlar and short-acting insulin doses were revised according to existing guidelines, while IDeg dose was revised based on an empirical individualized approach. At the arrival, insulin doses were reduced in 22 participants (-19.4±10.5%), while doses were increased in 17 children (+17.8±12.7%), based on individual needs. No statistically significant between-group difference emerged in mean blood glucose and glucose variability. No excess risk of hypoglycemia was found in the IDeg group. The study suggests similar effectiveness and safety of different insulin schemes when associated with appropriate diabetes education and management, and flexible dose adjustments. Despite its longer halflife and the lack of a validated algorithm, IDeg was not associated with an excess risk of hypoglycemia.
