[Digitization and Virtual Healthcare in a teaching hospital (Pisa, Italy) during COVID-19 emergency]. / Digitalizzazione e Virtual Healthcare nell'Azienda Ospedaliero Universitaria Pisana (AOUP) ai tempi dell'emergenza COVID-19.

The initial phases of COVID-19 emergency in Italy highlighted the technical delay that the national health system has accumulated in health services digitalization. Italian hospitals rapidly applied a demand systems for virtual health services based on tele-triage, tele-consultation and tele-visits procedures. This led, in the following months, the integration of virtual healthcare services applicable to the Azienda Ospedaliero Universitaria Pisa (AOUP). In particular, BCure system represents an important technological investment for the remote management of care protocols and the analysis of the complete use of health services. This is a unique system for sharing information between specialists, general practitioners and patients.

Possible role of nitric oxide in the biology of breast carcinoma: review of the available literature.

Nitric oxide was studied to investigate its possible involvement in the promotion of breast carcinoma: both the development of the primary tumour and the process of metastasis seem to be influenced by the presence and the amount of nitric oxide. We review the available literature on this topic, which seems to suggest an influence of nitric oxide on the cancer cell biology in breast carcinoma, but the argument is still controversial. More studies are needed to clarify the sequence of events and the real impact of nitric oxide on the behaviour of the disease.
