Misconduct found in 7 papers by Macchiarini, says English write-up of investigation

The Karolinska Institutet in Sweden has released an English translation of an external review that found Paolo Macchiarini, a celebrated surgeon who is credited with creating tracheas from cadavers and patients’ own stem cells, committed misconduct in a series of papers describing the work.

You can read the entire report, news of which was first reported by Sciencehere. The investigator, Bengt Gerdin, of Uppsala University, considered a series of allegations about Macchiarini’s papers, and found a number of them lived up to the verdict of misconduct. There were seven affected papers, not six, as was reported last week based on the initial findings (reported in Swedish).

For instance, in a 2014 Nature Communications paper describing the procedure in rats, Gerdin found that the scientists erred when none of the listed authors could assume responsibility for a CT image showing rats with “a smooth and patent oesophagus” (the researcher who took it asked to be left off the author list when he disagreed with how it was being interpreted), among other issues: Continue reading Misconduct found in 7 papers by Macchiarini, says English write-up of investigation

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: Continue reading “Super-surgeon” Macchiarini guilty of misconduct, external review finds

Surgeon Paolo Macchiarini, who is under investigation for allegedly downplaying dangers of an experimental surgery, has been cleared of some misconduct allegations by the Karolinska Institutet in Stockholm.

Macchiarini, a thoracic surgeon, has made headlines for repairing damaged airways using tracheas from cadavers and even synthetic tracheas, both treated with the patients’ own stem cells to assist in the transplant.

In a letter to Vice-Chancellor Anders Hamsten dated last month, KI’s Ethics Council refuted a number of accusations leveled against Macchiarini by Pierre Delaere at KU Leuven in Belgium, who had suggested the surgeon had engaged in scientific misconduct, including fabricating data.

The Ethics Council, however, disagreed:

We’re posting them here to allow researchers and clinicians to review and perhaps comment on them.

The complaint was from four surgeons at Karolinska Hospital, and was filed in August, as The New York Times reported last month. You can read the full complaint here. An excerpt: Continue reading Revealed: Complaint lodged against Macchiarini, “super-surgeon” under investigation

“Super-surgeon” who created artificial tracheas facing new misconduct allegations

A one-time media favorite is being accused of serious misconduct in three cases where he inserted artificial windpipes into patients and treated them with stem cells. Two of the patients have died; one survives, but needs her airway cleaned every four hours by hospital staff to keep her alive.

A little over two years ago, thoracic surgeon Paolo Macchiarini soared to the top and then sunk to the bottom within days. First, his work implanting artificial tracheas hit the front page of the New York TimesDays later he was placed on house arrest for accusations of fraud and extortion.

We wrote about him a month later, when a paper of his was retracted for plagiarism.

Here’s Henry Fountain at the NYT writing about the new allegations: Continue reading “Super-surgeon” who created artificial tracheas facing new misconduct allegations

“Misconduct” leads to retraction from Italian “super surgeon” under house arrest

Has the Annals of Thoracic Surgery had a change of heart? Evidently the publication that told us nearly two years ago, in effect, that the reasons for retractions in its pages were “none of [our] damn business” has decided that information is worth sharing after all.

The ATS has retracted a paper it published in October. The article, titled “Development and Validation of a New Outcome Score in Subglottic Stenosis,” came from a group of researchers in Florence, Italy.

As the notice explains: Continue reading “Misconduct” leads to retraction from Italian “super surgeon” under house arrest
