Trends and cyclic variation in the incidence of childhood type 1 diabetes in two Italian regions over 33 years and during the COVID-19 pandemic.

AIM: There is conflicting evidence about the impact of the COVID-19 pandemic on the incidence of type 1 diabetes. Here, we analysed long-term trends in the incidence of type 1 diabetes in Italian children and adolescents from 1989 to 2019 and compared the incidence observed during the COVID-19 pandemic with that estimated from long-term data. MATERIALS AND METHODS: This was a population-based incidence study using longitudinal data from two diabetes registries in mainland Italy. Trends in the incidence of type 1 diabetes from 1 January 1989 to 31 December 2019 were estimated using Poisson and segmented regression models. RESULTS: There was a significant increasing trend in the incidence of type 1 diabetes of 3.6% per year [95% confidence interval (CI): 2.4-4.8] between 1989 and 2003, a breakpoint in 2003, and then a constant incidence until 2019 (0.5%, 95% CI: -1.3 to 2.4). There was a significant 4-year cycle in incidence over the entire study period. The rate observed in 2021 (26.7, 95% CI: 23.0-30.9) was significantly higher than expected (19.5, 95% CI: 17.6-21.4; p = .010). CONCLUSION: Long-term incidence analysis showed an unexpected increase in new cases of type 1 diabetes in 2021. The incidence of type 1 diabetes now needs continuous monitoring using population registries to understand better the impact of COVID-19 on new-onset type 1 diabetes in children.

The role of grade of injury in non-operative management of blunt hepatic and splenic trauma: Case series from a multicenter experience.

This retrospective study shows the results of a 2 years application of a clinical pathway concerning the indications to NOM based on the patient's hemodynamic answer instead of on the injury grade of the lesions.We conducted a retrospective study applied on a patient's cohort, admitted in "Azienda Ospedaliero-Universitaria Ospedali Riuniti of Ancona" and in the Digestive and Emergency Surgery Department of the Santa Maria of Terni hospital between September 2015 and December 2017, all affected by blunt abdominal trauma, involving liver, spleen or both of them managed conservatively. Patients were divided into 3 main groups according to their hemodynamic response to a fluid administration: stable (group A), transient responder (group B) and unstable (group C). Management of patients was performed according to specific institutional pathway, and only patients from category A and B were treated conservatively regardless of the injury grade of lesions.From October 2015 to December 2017, a total amount of 111 trauma patients were treated with NOM. Each patient underwent CT scan at his admission. No contrast pooling was found in 50 pts. (45.04%). Contrast pooling was found in 61 patients (54.95%). The NOM overall outcome resulted in success in 107 patients (96.4%). NOM was successful in 100% of cases of liver trauma patients and was successful in 94.7% of splenic trauma patients (72/76). NOM failure occurred in 4 patients (5.3%) treated for spleen injuries. All these patients received splenectomy: in 1 case to treat pseudoaneurysm, (AAST, American Association for the Surgery of Trauma, grade of injury II), in 2 cases because of re-bleeding (AAST grade of injury IV) and in the remaining case was necessary to stop monitoring spleen because the patient should undergo to orthopedic procedure to treat pelvis fracture (AAST grade of injury II).Non-operative management for blunt hepatic and splenic lesions in stable or stabilizable patients seems to be the choice of treatment regardless of the grade of lesions according to the AAST Organ Injury Scale.
