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

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

Report: Fujii faked data in at least 172 papers

A Japanese web site is reporting that Yoshitaka Fujii, a Japanese anesthesiologist suspected of widespread data fabrication, did indeed fake his results in at least 172 published studies.

According to the article, on a site called Jiji Press: Continue reading Report: Fujii faked data in at least 172 papers

Withdraw that emotion: Psych journal retracts two Stapel papers on mood

Two more papers from Dutch fraudster Diederik Stapel have been retracted. Both appeared in the journal Psychological Science in 2008, with the same, evidently unwitting co-author, Kirsten Ruys, of Tilburg University.

Here is the notice: Continue reading Withdraw that emotion: Psych journal retracts two Stapel papers on mood

Is post-hoc statistical analysis the new fraud detection tool? A new review looks at fraudster Reuben’s work

In the beginning, there was Scott Reuben.

Well, not quite. Reuben, a Massachusetts anesthesiologist who fabricated data and briefly topped our list of most-retracted authors, didn’t invent research fraud, although he did spend six months in federal prison for his crimes. But his case was in no small measure responsible for the birth of this blog, and, well, the rest of human history that followed.

Although Reuben’s retractions are behind him now — his count ends at 22 — and other scientists, including two anesthesiologists, Joachim Boldt and Yoshitaka Fujii, have or likely soon will dramatically eclipsed his mark, a new paper has revisited his publications with an eye toward seeing if they could identify statistical evidence of data manipulation. It’s the same  kind of effort that Ed Yong highlighted as noteworthy about the Dirk Smeesters case, which we covered yesterday and which involved an anonymous statistically inclined whistleblower.

Before we get to whether there was evidence of such manipulation Continue reading Is post-hoc statistical analysis the new fraud detection tool? A new review looks at fraudster Reuben’s work

Following investigation, Erasmus social psychology professor retracts two studies, resigns

Dirk Smeesters

The social psychology community, already rocked last year by the Diederik Stapel scandal, now has another set of allegations to dissect. Dirk Smeesters, a professor of consumer behavior and society at the Rotterdam School of Management, part of Erasmus University, has resigned amid serious questions about his work.

According to an Erasmus press release, a scientific integrity committee found that the results in two of Smeesters’ papers were statistically highly unlikely. Smeesters could not produce the raw data behind the findings, and told the committee that he cherry-picked the data to produce a statistically significant result. Those two papers are being retracted, and the university accepted Smeesters’ resignation on June 21.

The release also takes pains to say that the university has no reason to doubt the work of his co-authors. You can read the complete report in Dutch, with Smeesters’ co-authors’ names blacked out, in an NRC Handelsblad story.

Erasmus tells Retraction Watch that these are the two papers being retracted: Continue reading Following investigation, Erasmus social psychology professor retracts two studies, resigns

Three more retractions for weight loss surgeon Edward Shang for making up data

Edward Shang, the weight loss surgeon who lost his job at the University of Leipzig in May after it was revealed that he had made up most, if not all, of the patients in his research studies at the University of Mannheim, has retracted three more papers.

Here’s the notice, which is a bit, um, lean, given what we know about the case: Continue reading Three more retractions for weight loss surgeon Edward Shang for making up data

Three more Fujii papers fall for lack of IRB approval

Three journals under the JAMA umbrella are retracting papers by Yoshitaka Fujii, the Japanese anesthesiologist accused of research misconduct so sweeping that it might net him the record for most retractions by a single author.

The papers, in the Archives of Surgery, Archives of Ophthalmology and the Archives of Otolaryngology — Head & Neck Surgery, were published in 2001 and 2005.

Here are the notices, which are essentially identical but for the titles of the articles: Continue reading Three more Fujii papers fall for lack of IRB approval

Resveratrol researcher Das in video: Yes, I manipulated images, but only because the journals asked me to

Das, via UConn

Dipak Das, who until earlier this year ran a high-profile cardiovascular research center at the University of Connecticut, has recorded a slick looking video defense against allegations that he cooked data and manipulated images in scores of published studies, 12 of which have been retracted to date.

Das, who was hit with a 60,000 pages of allegations stemming from a three-year investigation by the university, spends the bulk of the documentary-style interview — which is available on YouTube — talking about the wonders of resveretrol. But he gets into the misconduct charges at about the 15-minute mark.

Catching up: Charges against CFS-XMRV researcher Mikovits dropped, ‘gyres’ author Andrulis publishes another paper

A follow-up on two stories we’ve covered here at Retraction Watch:

1. Criminal charges against chronic fatigue syndrome researcher dropped

The state of Nevada has dropped criminal charges against Judy Mikovits, the embattled chronic fatigue syndrome (CFS) researcher whose paper linking the condition to a virus, XMRV, was retracted last year by Science.

As we reported in November, Mikovits was arrested in Ventura County, California on an “out of county warrant” from Washoe County, Nevada, for allegedly taking lab notebooks, a computer, and other material from the Whittemore Peterson Institute in Reno, Nevada, after the WPI fired her in September.

The first report on the dropped charges was apparently by Mikovits’ friend Lilly Meehan on Facebook, news that was picked up by the ProHealth website on June 13 (their post has since been updated). Later that day, ScienceInsider’s Jon Cohen, who has been covering the case closely, reported that Continue reading Catching up: Charges against CFS-XMRV researcher Mikovits dropped, ‘gyres’ author Andrulis publishes another paper

Shikeagi Kato, who resigned post in March, retracts Nature paper

Shikeagi Kato, an endocrinologist formerly of the University of Tokyo who resigned on March 31 amidst an investigation into his work, has retracted another paper, this one in Nature.

Here’s the notice for “DNA demethylation for hormone-induced transcriptional derepression,” which was the subject of a correction last October: Continue reading Shikeagi Kato, who resigned post in March, retracts Nature paper
