Ethics approval and consent to participate

: Ethical approval for this study was obtained from the Institutional Review Board of the University of Padua. In agreement with Italian national regulation on retrospective observational studies that do not imply experimentation on the patients or deviation from the standard clinical practice, the need for patient’s written informed consent was waived. All participants gave instead verbal informed consent to the treating physician with the presence of a witness. The expressed consent was reported on the patient’s clinical file together with the agreement of the personal data handling, which is always obtained at the beginning of hospitalization. All analyses were carried out on anonymised data.
