Half of anesthesiology fraudster’s papers continue to be cited years after retractions

with 6 comments

ethicsIn yet more evidence that retracted studies continue to accrue citations, a new paper has shown that nearly half of anesthesiologist Scott Reuben’s papers have been cited five years after being retracted, and only one-fourth of citations correctly note the retraction.

According to the new paper, in Science and Engineering Ethics: Read the rest of this entry »

What happened to Joachim Boldt’s 88 papers that were supposed to be retracted?

with 11 comments

a&amisconductcoverCHICAGO — Almost two years after editors at 18 journals agreed in March 2011 to retract 88 of former retraction record holder Joachim Boldt’s papers, 10% of them hadn’t been retracted.

That’s what Nadia Elia, Liz Wager, and Martin Tramer reported here Sunday in an abstract at the Seventh International Congress on Peer Review and Biomedical Publication. Elia and Tramer are editors at the European Journal of Anaesthesiology, while Wager is former chair of the Committee on Publication Ethics (COPE).

As of January 2013, nine of the papers hadn’t been retracted, Tramer said, while only five — all in one journal — had completely followed COPE guidelines, with adequate retraction notices, made freely available, along with  PDFs properly marked “Retracted.” From the abstract (see page 18): Read the rest of this entry »

Retraction record broken, again: University report should up Fujii total to 183

without comments

a&amisconductcoverKeeping up with the various investigations into the activities of Yoshitaka Fujii — the assumed record holder for retractions by a single author, with 172 likely — can be a challenge. Between the journals pulling his papers and the institutions looking into his misconduct, it’s hard to keep everything straight.

But we have a new report, from a past employer, that makes for interesting reading and helps tie up some loose ends. The document is from Tsukuba University, where Fujii worked more than a decade ago when questions about the propriety of his findings first surfaced. Read the rest of this entry »

Expressions of regret: group retracts sedation paper for stolen words, data

with one comment

A group of researchers in China have retracted a 2011 article in Acta Pharmacologica Sinica, the official journal of the Chinese Pharmacological Society, acknowledging that they lifted text and results from a previously published paper from other researchers.

The paper was titled “Lipid metabolism disturbances and AMPK activation in prolonged propofol-sedated rabbits under mechanical ventilation.”

Does anesthesiology have a problem? Final version of report suggests Fujii will take retraction record, with 172

with 7 comments

Japanese investigators have concluded that Yoshitaka Fujii, an expert in postoperative nausea and vomiting whose findings drew scrutiny in 2000 but who continued to publish prolifically for a decade after, fabricated his results in at least 172 published studies.

That number nearly doubles that of the current unofficial retraction record holder, Joachim Boldt.

An inquiry by the Japanese Society of Anesthesiologists (JSA) has determined that Fujii, who was fired in February from his post at Toho University, falsified data in 172 of 212 papers published between 1993 and 2011. Investigators said they found no evidence of fraud in three of the papers, but could not determine whether the results reported in the remaining 37 were reliable.

Of the 172 bogus studies, 126 involved randomized controlled trials. Investigators believe this was not a coincidence: Read the rest of this entry »

193 papers could be retracted: Journal consortium issues ultimatum in Fujii case

with 8 comments

A group of editors representing nearly two dozen medical journals has issued an ultimatum of sorts to officials at seven Japanese institutions that once employed Yoshitaka Fujii: Validate the papers of the disgraced anesthesiologist or they will be retracted.

Fujii, as we have reported, was fired by Toho University in late February, putatively for failing to obtain ethics approval for a handful of his studies. That much may be true, but the integrity of his data has been in question for more than a decade. At the time of his dismissal, journal editors expressed concern that the university would not pursue an inquiry into Fujii’s data.

Last month, the journal Anaesthesia published a statistical analysis of Fujii’s research bya UK anesthesiologist named John Carlisle which cast serious doubt on the veracity of the studies.

The joint letter forces the question. Read the rest of this entry »

Update on Fujii: Anesthesia journal finds overwhelming statistical evidence of data fabrication

without comments

There’s a bit more this afternoon on the story of Yoshitaka Fujii, the Japanese anesthesiologist accused of fraud and other misconduct that we reported on yesterday.

The British journal Anaesthesia, which has been looking into Fujii’s research record, has posted four articles and editorials about the case and related issues on its website. One in particular is remarkable for its conclusions. Written by a UK anesthesiologist named John Carlisle, the article claims to have analyzed 169 randomized controlled trials that Fujii conducted between 1991 and 2011.

According to the abstract (which we formatted for readability, and which should be online shortly, we’re told): Read the rest of this entry »

Major fraud probe of Japanese anesthesiologist Yoshitaka Fujii may challenge retraction record

with 11 comments

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.
