“The correct values are impossible to establish:” Embattled nutrition researcher adds long fix to 2005 paper

A Cornell food researcher who has pledged to re-analyze his papers following heavy criticism of his work has issued a major correction to a 2005 paper.

The correction tweaks two tables, a figure, and the description of the methodology — and notes in two instances the correct findings are unknown, since the original data are unavailable. Andrew Gelman, a statistician at Columbia University and critic of Brian Wansink’s work, has dubbed the notice the “best correction ever.”

The paper, about whether changing the name of food influences its taste, was not among the batch of papers initially flagged by critics last year. Since then, researchers have raised additional questions about Wansink’s work; one of his papers was retracted in April. That same month, an internal review by Cornell University concluded that Wansink made numerous mistakes, but did not commit misconduct.

When we contacted Wansink about the correction, we received this statement from the Cornell Food and Brand Lab, which Wansink directs:

Fake peer review strikes again for pair of authors

Two authors who had a paper retracted for fake peer review in 2015 have lost another for the same reason.

Elsevier recently retracted the second paper by the duo, a 2015 paper in a cancer journal, after finding evidence of fake peer review. The paper was submitted in October 2014 and accepted just a week before our piece on fake peer review appeared in Nature.

According to the notice, after investigating the paper, which appeared in Cancer Letters, the publisher concluded that it was accepted “based upon the positive advice of at least two faked reviewer reports.” The notice also explained that the identities of several authors “could not be confirmed.” Continue reading Fake peer review strikes again for pair of authors

Quick: What does fish food have to do with X-rays? In this case, an Elsevier production error

In 2012, a study claiming to show — after some intentional statistical tricks — that a dead salmon had brain activity in an fMRI won a prestigious (and hilarious) Ig Nobel Prize.

So five years later, when Bálint Botz tweeted wryly about a study of fish and plants in a radiology journal, we thought, “Aha, someone is trying to create another red herring!”

But alas, it turns out the reason a journal normally concerned with X-rays would suddenly be interested in aquaponics was far more prosaic: Continue reading Quick: What does fish food have to do with X-rays? In this case, an Elsevier production error

Drug researcher up to ten retractions

A pharmaceutical researcher has received his tenth retraction. The reason, once again: duplicating his previous work.

Giuseppe Derosa, based at the University of Pavia in Italy, lost a 2011 paper this month after journal editors identified “substantial duplication of an earlier published paper.” According to the notice, the authors failed to cite the previous work and to disclose that the manuscript had been published or was under consideration elsewhere.

Derosa has a habit of reusing clinical trial data in multiple papers. He received his first four retractions in 2015 for publishing the same clinical trial results six times—two of those papers were retracted over the summer and two more several months later. By 2016, a fifth from the bunch was retracted (one of the six still stands). Derosa received another retraction, citing duplication (which we covered here and which was not related to the six clinical trials).

Journal retracts nine papers in one day by author under investigation at the Weizmann Institute

On April 27, the Journal of Biological Chemistry (JBC) retracted nine papers by a researcher based in Israel, including some dating back to 2000.

The reason: Image manipulation.

Michal Neeman, vice president of The Weizmann Institute of Science, told us that the researcher, Rony Seger, is under investigation following an allegation of misconduct affecting papers in multiple journals.

So far, we’ve found 11 retractions for papers by Seger, a molecular biologist. In the notices, the authors state they have “full confidence” in the findings, and in many instances have replicated the work.

According to Neeman:

Journal retracts paper eight months after U.S. Feds announce findings of misconduct

In August, the U.S. Office of Research Integrity announced that a former postdoctoral fellow at the National Human Genome Research Institute (NHGRI) doctored data in two published papers.

It took one journal a little longer than five months to remove the researcher’s name from the co-author list, and replace one figure.

It took the second journal more than eight months to retract the paper.

Here’s the notice for “A BLOC-1 Mutation Screen Reveals that PLDN Is Mutated in Hermansky-Pudlak Syndrome Type 9,” published by the American Journal of Human Genetics (AJHG):

Despite author’s protest, journal removes paper on emergency department prices

A journal has temporarily removed a paper showing the dramatic differences in the cost of providing emergency care that caught national attention (and some criticism from emergency care providers), despite the first author’s claims that the results are valid.

The paper, published online in February by the Annals of Emergency Medicine, showed that it can cost significantly more for patients to be treated at emergency departments than at urgent care centers, even for the same conditions. Soon after the paper was published, first author Vivian Ho at Rice University was told by the American College of Emergency Physicians, which publishes the journal, that there were some errors in the appendix, and they wanted to reanalyze the entire paper.

Ho told us:

A university asked for numerous retractions. Eight months later, three journals have done nothing.

Anil Jaiswal

When journals learn papers are problematic, how long does it take them to act?

We recently had a chance to find out as part of our continuing coverage of the case of Anil Jaiswal at the University of Maryland, who’s retracted 15 papers (including two new ones we recently identified), and has transitioned out of cancer research. Here’s what happened.

As part of a public records request related to the investigation, we received letters that the University of Maryland sent to 11 journals regarding 26 “compromised” papers co-authored by Jaiswal, four of which had been retracted by the time of the letter. The letters were dated between August and September 2016 (and one in February) — although, in some cases, the journals told us they received the letter later. Since that date, three journals have retracted nine papers and corrected another, waiting between four and six months to take action. One journal published an editorial note of concern within approximately two months after the university letter.

And six journals have not taken any public action.

A shadow was cast on a bone researcher’s work. What are journals doing about his papers?

Last year, a researcher cast doubt on a bone scientist’s clinical trials, suggesting some of the findings may not be legitimate. So what’s happened since?

Since 2015, journals have retracted 14 papers by bone researcher Yoshihiro Sato, based at Mitate Hospital in Japan, for issues ranging from self-plagiarism, to problems with data, to including co-authors without their consent. (We covered the latest two retractions this week.) Last year’s analysis identified patterns in more than 30 of Sato’s clinical trials that suggest systematic problems with the results. (Sato has defended his research.)

With doubts cast on Sato’s body of work, we contacted the journals that have published his papers involving human trials, to see if any taken another look at Sato’s work; several responded. While most believe there is little reason to take further action at this time, some told us they are investigating.

Prominent physicist loses four more papers for duplication

A leading physicist in India has lost four more papers for duplication, after colleagues lodged a complaint against him.

According to the most recent retraction notices, issued by Applied Surface Science, the four papers duplicated several figures and portions of text from the authors’ previous works. Although the notices do not single out a responsible party, last year the Mumbai Mirror reported that first and corresponding Naba K. Sahoo had been accused of duplication by colleagues at the Bhabha Atomic Research Centre (BARC), part of Indian government’s Department of Atomic Energy.

(In a bizarre twist, Sahoo also made the news recently for getting into a fist fight with another BARC scientist.)

Sahoo received two retractions last year for duplication, sometimes inelegantly referred to as “self-plagiarism.” All six of his retractions affect papers published by Applied Surface Science between 2005 and 2007.

The first retraction notice explains that a 2006 paper lifted portions of text from an earlier paper by Sahoo: Continue reading Prominent physicist loses four more papers for duplication
