Co-author of retraction record-holder likely fabricated his own data, analysis shows

with 2 comments

In 2012, John Carlisle, a British anesthesiologist, demonstrated conclusively using statistics that Yoshitaka Fujii had faked data in many studies. Fujii — as followers of this blog well know — now holds the record for most retractions by an individual author (183).

Carlisle’s work accomplished two things: It put to rest any doubt that problems with Fujii’s work might have resulted from innocent mistakes, and it gave journals a mathematical tool for conducting investigations into potential cases of misconduct.

Now comes the payoff. In a new paper, Carlisle and another anesthesiologist, John Loadsman, take aim at one of Fujii’s frequent co-authors, Yuhji Saitoh of Yachiyo Medical Center and Tokyo Women’s Medical University in Japan. The pair analyzed data from 31 studies Saitoh published between 1993 and 2012 — including one study that was rejected in 2015 — for a total of 32 papers. Of those, 23 did not include Fujii as an author.

Writing in the journal Anaesthesia, where Carlisle published his first study about Fujii, he and Loadsman state that: Read the rest of this entry »

Catching up: Publisher to pull four papers by retraction record holder flagged years ago

without comments

the-laryngoscopeJournals published by Wiley are retracting four papers by Yoshitaka Fujii, the anesthesiology researcher with the most retracted scientific papers.

Retraction Watch readers will be familiar with Fujii’s case: He currently holds the number one spot on our leaderboard with more than 180 retractions, some of which are pending. (That’s nearly twice the number of retractions by the researcher in the #2 spot, Joachim Boldt.) 

Earlier this year, The Breast Journal and The Laryngoscope — both of which are published by Wiley-Blackwell — issued expressions of concern (EOCs) for a total of four papers by Fujii. All four papers were included in a 2012 analysis of 168 of Fujii’s studies by J. B. Carlisle, a consultant anesthetist in the UK, who concluded that the chance of much of Fujii’s data appearing the way it does naturally is

…the chance of selecting one particular atom from all the human bodies on earth.

Now, both journals are retracting the papers.

Anesthesia journal pulls study lacking patient consent

without comments

Journal of AnesthesiaAn anesthesia journal has retracted a paper after an author admitted that the study did not obtain appropriate consent from patients receiving a neuromuscular block in muscles on the face and hands. 

The first author, Yuhji Saitoh, has the same name as a co-author of Yoshitaka Fujii, the all-time record holder with 183 retractions listed on our leaderboard. Thirty-six of those retracted papers include a co-author with the name of Yuhji Saitoh, but we were unable to confirm this is the same person listed on the newly retracted paper.  

Here’s the retraction notice, issued by the Journal of Anesthesia on August 11: Read the rest of this entry »

Pro-lifers call for JAMA to retract 2005 paper about fetal pain

with 10 comments

JAMAPro-life activists have asked JAMA to retract a 2005 paper that suggested fetuses can’t feel pain before the third trimester.

Critics are arguing that newer findings have shown pain sensation appears earlier in gestation, yet the 2005 data continue to be cited in the discussion around abortion. What’s more, they note, some of the authors failed to mention their ties to the abortion industry.

The 2005 paper has been cited 191 times, according to Thomson Reuters Web of Science. We spoke with Howard Bauchner, Editor in Chief at JAMA and The JAMA Network, who told us something similar to what he said last week, when PETA asked to retract a paper they claim could be harmful to elephants: Read the rest of this entry »

The standard in transparency? Editor praises author honesty that led to retraction in anesthesia journal

with 5 comments

a&Amay16

Sometimes, a junior member of the team sees things an editor-in-chief misses.

Regular readers know that we’re always delighted when we get a chance to commend researchers and journals for doing the right thing. Here’s an example that sets the standard.

Anesthesia & Analgesia (A&A) is retracting a 2015 paper which purportedly found important differences in patient outcomes based on the quality of their anesthesiologists. The trouble with the article: Read the rest of this entry »

Retracted anesthesia study “was not conducted in reality”

with 3 comments

coverWe’ve come across a new way to say the data in a paper are not reliable:

It has been found that the study represented in the article was not conducted in reality.

That’s from the retraction note for a paper that Anesthesia Essays and Researches has retracted for data falsification. The rest of the retraction note for “Intrathecal dextmedetomidine to reduce shoulder tip pain in laparoscopic cholecystectomies under spinal anesthesia” explains:

Labor pains study brought into this world twice

without comments

YJPAI_v16_i6_COVER.inddA group of authors published two articles about one study on pain during childbirth, so one journal is retracting it.

This may seem like a standard case of salami slicing — but this one comes with a nearly 600-word commentary co-authored by the editors of the two journals in question.

The commentary lays out — in a refreshingly transparent way — exactly why the journals came to a joint decision to retract one of the papers:

2001 Fujii papers retracted — finally. What took so long?

with one comment

BJO

Nearly four years after an analysis of more than 160 papers by Yoshitaka Fujii concluded the chances the data were authentic were infinitesimally small, the British Journal of Ophthalmology has decided to formally retract one of the papers included in that review.

The name Yoshitaka Fujii should ring a bell — an alarm bell, in fact — for our readers. He’s firmly listed in the number one spot on our leaderboard, with more than 180 retractions.

The recently retracted paper — “Ramosetron compared with granisetron for the prevention of vomiting following strabismus surgery in children” — has been included in that retraction total for years, because it was part of a seminal 2012 analysis by J.B. Carlisle that put the odds of data occurring naturally in some of Fujii’s papers at: Read the rest of this entry »

Scott Reuben notches 25th retraction, for a letter to the editor

without comments

Screen Shot 2015-11-18 at 11.08.26 AMAnother domino has fallen for the infamous and prolific former anesthesiologist Scott Reuben. This time it’s a retraction for a letter to the editor that cites one of his since-retracted papers.

The letter, published in 2001, argues that local anesthesia is a “safe, reliable, inexpensive, and practical alternative to the use of epidural, spinal, or general anesthesia” for outpatient knee surgery. But to support his point, he uses one of his papers that has since been retracted for data fabrication.

The note from Anesthesia & Analgesia explains:

Boldt’s retraction count upped to 94, co-author takes legal action to prevent 95th

with 2 comments

Screen Shot 2015-09-16 at 12.12.13 AM

We’ve found two recent retractions and an expression of concern for Joachim Boldt, former prominent anesthesiologist and currently Retraction Watch leaderboard’s 2nd place titleholder. He now has 94 retractions.

One of the retracted articles contains falsified data, along with a researcher who didn’t agree to be a co-author, according to an investigation by the Justus Liebig University Giessen, where Boldt used to work. The expression of concern is regarding some questionable data. The other new retraction is actually one of 88 papers that a group of editors agreed to retract back in 2011, after they were “unable to verify” approval by the Institutional Review Board (IRB) for the studies.

One of those 88 papers, we’ve discovered, has still has not been retracted. According to an editor at the journal, they haven’t removed it because one of Boldt’s co-authors has threatened them with legal action. Read the rest of this entry »
