RESUMEN
The present work, based on the results found in the literature, yields a consistent model of SARS-CoV-2 survival on surfaces as environmental conditions, such as temperature and relative humidity, change simultaneously. The Enthalpy method, which has recently been successfully proposed to investigate the viability of airborne viruses using a holistic approach, is found to allow us to take a reasoned reading of the data available on surfaces in the literature. This leads us to identify the domain of conditions of lowest SARS-CoV-2 viability, in a specific enthalpy range between 50 and 60 kJ/Kgdry-air. This range appears well-superimposed with the results we previously obtained from analyses of coronaviruses' behaviour in aerosols, and may be helpful in dealing with the spread of infections. To steer future investigations, shortcomings and weaknesses emerging from the assessment of viral measurement usually carried out on surfaces are also discussed in detail. Once demonstrated that current laboratory procedures suffer from both high variability and poor standardisation, targeted implementations of standards and improvement of protocols for future investigations are then proposed.

(1) Background: Eating Disorders (EDs) are severe psychiatric disorders with high rates of mortality, multiple medical and psychiatric comorbidities associated, and often chronic illness. Historically, EDs are among the most gendered of psychiatric illnesses, and male presentations have been perceived as rare and unusual. This perception resulted in the systematic underrepresentation of males in research on Eds, and as consequence, in a scarcity of research investigating clinical and psychological features in this population. (2) Methods: The present study aims to evaluate clinical and psychopathological features in a sample of 287 children and adolescents, 27 males and 260 females with EDs, in order to identify similarities and differences. (3) Results: Males were younger than females, with similar medical and clinical conditions, but a different distribution of typology of EDs in middle childhood and middle adolescents. The Eating Disorders Inventory-3, TAS-20 for alexithymia and CDI for depressive symptoms' profiles are similar, while males showed higher scores at the global indexes of Symptom Checklist 90-Revised test in early adolescence. (4) Conclusions: Results suggest gender-specific similarities and differences in clinical and psychological features in children and adolescent males, which may require specific diagnosis and treatment.
