The Karolinska Institute’s latest decision includes a guilty verdict for one of the whistleblowers who contributed to the investigation.

The group calls for the retraction of six publications by surgeon Paolo Macchiarini regarding the synthetic trachea transplantations that led to the death of at least three patients. 

Tissue recipients were treated as “guinea pigs,” says investigation leader.

The embattled thoracic surgeon is dealt another blow by his former employer, which is calling for the retraction of one of his papers on artificial esophagus research.

A whistleblower asked to have his named pulled from a study led by the embattled surgeon.

The Karolinska Institute has rejected the conclusions of an earlier, independent investigation, finding regenerative medicine researcher Paolo Macchiarini not guilty of scientific misconduct.

An independent investigator says that the surgeon misrepresented the truth in papers about artificial trachea transplants.

An investigation has found the thoracic surgeon who transplanted artificial tracheae into patients not guilty of overhyping his research.

The scientist who implanted artificial windpipes into several patients is being accused of conducting the procedures without proper ethical review.
