Background Social distancing and quarantine imposed by the authority during the COVID-19 pandemic caused restrictions, which had a negative impact on eating behavior, especially among adolescents. We proposed a retrospective study aimed to evaluate the effect of the COVID-19 pandemic on eating disorders risk and symptoms. Methods In this study, a group of 127 pediatric patients (117 females and 10 males) with eating disorders admitted to the Bambino Gesù Children’s Hospital of Rome (Italy), in the period between August 2019 and April 2021, was analyzed. All patient data were collected from patients’ electronic medical records. Results We found that 80.3% of patients were at the onset of eating disorders and that 26% of patients had familiarity for psychotic disorders. Often these patients had comorbidities and alterations in blood parameters such as leukocytopenia, neutropenia, hypovitaminosis and hormonal problems that could affect their future. Conclusions Our findings could provide a framework for developing clinical and educational interventions to mitigate the short- and long-term negative impact of the pandemic on adolescent future health.

The exposure of the epidermoid cell line A431 to different concentrations of CsCl was assessed using different methodological approaches. Two different effects were detected depending upon the concentration of the agent: at low concentrations, cell modification was represented mainly by a very pronounced cell flattening and an alteration of the cell-to-cell contacts, interpreted as an increase in cell adhesion. At higher concentrations, a clear pathogenic effect was observed that allowed the formulation of the hypothesis that specific mechanisms of toxicity at the subcellular level involving mitochondrial and cytoskeletal function can exist. In addition, membrane order parameters, as detected by electron paramagnetic resonance (EPR) spectroscopy, displayed a dose-dependent increase in membrane rigidity. Results reported here seem to suggest that cesium ions can enter the cell, modify plasma membrane integrity and alter some specific cytoplasmic components, e.g. the cytoskeleton. Considering that environmental contamination by cesium as a result of radioactive fallout is of major importance and that few data are available thus far on this matter, this study provides evidence for the possible mechanisms of action of the non-radioactive form of this ion in cells.
