Paolo Macchiarini, the celebrated surgeon whose work has come under scrutiny in Italy and at the Karolinska Institutet in Sweden, committed misconduct in six papers, according to an external reviewer.
Macchiarini is best known for creating tracheas from cadavers and patients’ own stem cells. The findings of the external review, first reported yesterday by SvD Nyheter, were made public last week. They are only available in Swedish thus far, and we have requested a copy from the Karolinska.
External reviewer Bengt Gerdin, of Uppsala University, summarized his findings this way for Retraction WAtch:
The report says the Paolo Machiarini was guilty of scientific misconduct by presentation of fabricated data or other type of information in some cases and omission of relevant data in other cases.
Gerdin told SvD Nyheter (via Google Translate):
themisconduct is serious, the big question is whether one should teach young talented people a standard of how to behave, and you will see that it is done this way. It is an extremely bad example for young researchers.
Asked for a response, Macchiarini tells Retraction Watch he can’t comment until he has seen an English translation.
This is one of two reviews commissioned by the Karolinska. The other cleared him of different misconduct allegations brought by Pierre Delaere. An investigation in Italy has also cleared him of most charges.
Update, 10 a.m. Eastern, 5/21/15: Here’s a copy of the report, in Swedish. We’ve also struck through a word in Gerdin’s SvD Nyheter quote after hearing from a Swedish reader that the Google Translate translation was imprecise (as is often the case).
