We have learned that a widely published Japanese anesthesiologist is under investigation by his university over concerns that he engaged in repeated fraud for decades that has tainted roughly 180 articles—many of which may be retracted as a result.
In a related move, the journal Clinical Therapeutics is retracting papers by the researcher, Yoshitaka Fujii, most recently of Toho University, in Tokyo. Judy Pachella, managing editor of the journal, confirmed the retractions but would not state how many papers were affected. Clinical Therapeutics published 17 articles by Fujii, between 2003 and 2010.
