The original version of this article unfortunately contained a mistake. Two of the authors forgot to mention recent collaborations in their COI. The correct COI would have been: Dr Silvia Mongodi received feed for lectures from General Electrics; and Professor Francesco Mojoli received feed for lectures from General Electrics, Hamilton Medical and SEDA SpA. The Authors apologise for the missing information.
