The string of apparent bad luck continues for Stanley Rapoport.

Rapoport, a neuroscientist based at the U.S. National Institute on Aging, has lost three more papers in three journals due to the misconduct of his co-authors. By our count, these retractions bring his tally to 19 — and tie him for 21st place on our leaderboard.

The journals—Schizophrenia Research, Journal of Affective Disorders, and Biological Psychiatry— retracted the papers because the National Institutes of Health had found that one of Rapoport’s co-authors, Jagadeesh Rao, had “engaged in research misconduct by falsifying data.” Rao was corresponding author on all three papers.

According to a spokesperson for Elsevier, which publishes the journals, the Schizophrenia Research paper was retracted in July, the JAD paper in late May and the Biological Psychiatry paper in late April. The spokesperson told us that the publisher first received an email from the NIH about the misconduct findings on September 20, 2016, and that: Continue reading NIH neuroscientist up to 19 retractions

Diabetes researcher who sued to prevent retractions now has 13

A diabetes researcher who sued a publisher to protect several papers from being retracted recently received his 13th, in a prestigious gastroenterology journal.

Mario Saad, based at the University of Campinas in São Paulo, Brazil, has had a string of retractions over the past few years, including four in Diabetes after he lost a legal battle with the American Diabetes Association.

The latest retraction appears in Gastroenterology, citing possible image duplication. Saad is second-to-last author on the 2012 paper.

According to the retraction notice, the journal investigated data in several figures, and believes some were duplicated. The authors explained that the duplications resulted from inadvertently using wrong blots; still, the editors chose to retract the paper after determining they no longer had confidence in its conclusions.  

Here’s the retraction notice for “Obesity-Induced Increase in Tumor Necrosis Factor-α Leads to Development of Colon Cancer in Mice:” Continue reading Diabetes researcher who sued to prevent retractions now has 13

Volunteer researcher faked weeks’ worth of data

A volunteer researcher at Florida Atlantic University fabricated the results of mouse experiments over a 14-day period in June, 2016, according to a new finding issued by the U.S Office of Research Integrity (ORI).

According to the ORI, Alec Mirchandani made up the results of behavioral experiments to make it seem as if he had done the work, and falsified animal transfer logs, which affected research supported by the National Institute of Mental Health.

More specifically, the ORI determined that Mirchandani had “knowingly and intentionally:”

Authors say patient threatened legal action after being subject of scholarly paper

A patient appears to have had a change of heart about being featured in a case report.

The patient cannot be identified in the paper published in Journal of Gastrointestinal and Liver Diseases. However, according to the retraction notice, she threatened to sue if the authors did not withdraw it. After receiving the threat, the paper’s corresponding author, Mariano Sica, told us that the authors immediately asked the journal to retract the paper.

We’ve written about similar cases where patients do not provide informed consent or withdraw it, but in this case we haven’t seen the threat ourselves.

We asked Sica if we could see the legal threat, and he said he couldn’t share it, explaining: Continue reading Authors say patient threatened legal action after being subject of scholarly paper

“We were devastated:” Authors retract paper after realizing they had used the wrong mice

Raymond Pasek and Maureen Gannon

Longtime readers of Retraction Watch may recall a 2011 post about a research team that retracted a paper after realizing that they had ordered the wrong mice. Maureen Gannon and Raymond Pasek of Vanderbilt University contacted us earlier this week to alert us to a similar case: Their retraction, earlier this month, of a 2016 paper from American Journal of Physiology – Endocrinology and Metabolism after discovering that “a colleague from another lab had mistakenly supplied us with the wrong transgenic mouse line.”

“We strongly believe that sharing this example will encourage other researchers to do the right thing when a mistake is discovered and promote academic integrity,” they wrote. So we asked them to answer a few questions about their experience with “Connective tissue growth factor is critical for proper β-cell function and pregnancy-induced β-cell hyperplasia in adult mice,” a paper that has been cited twice, according to Clarivate Analytics’ Web of Science.

More notices appear for embattled Cornell food researcher

Journals have posted two corrections alongside papers by Brian Wansink, a food researcher whose work has lately come under fire.

One of the corrected papers was among the initial batch that raised eyebrows last year; after Wansink praised the productivity of one of his researchers, critics suggested four papers contained critical flaws. The questions about his work soon extended to other papers, one of which was retracted in April. That month, an internal review by Cornell University announced that Wansink made numerous mistakes, but did not commit misconduct. Wansink has pledged to reanalyze multiple papers.

One paper that was among those initially criticized has received a formal correction notice from the Journal of Product & Brand Management. The notice, which appears behind a paywall, has drawn fire from a regular critic of Wansink’s work, Jordan Anaya, who argues “this correction actually needs a correction, actually several.”

Here’s the notice for “Peak-end pizza: prices delay evaluations of quality:”

Lancet retracts (and replaces) paper a year after authors report error that changes “all numbers”

In March 2016, researchers in Switzerland and Canada published a meta-analysis in The Lancet, exploring the optimal painkiller and dose for treating pain in knee and hip osteoarthritis. Soon after, the authors were informed of an error that would change “all numbers” in a paper that may influence clinical practice.

The authors contacted The Lancet immediately, in July 2016, to inform them of the issue. Sven Trelle, the paper’s corresponding author, also told us: Continue reading Lancet retracts (and replaces) paper a year after authors report error that changes “all numbers”

“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:

Researcher who tangled with CrossFit loses two more papers

An exercise scientist who ran a study of the CrossFit exercise program without an approved human subjects protocol has lost two more papers to retraction.

Both papers were retracted on June 26 by the editors of the International Journal of Exercise Science (IJES) with the agreement of last author Steven Devor, a former professor at The Ohio State University. Both have been retracted because the studies were carried out without proper IRB approval.

Earlier in June, another paper from the CrossFit study — which is still at the center of a legal battle between CrossFit and a competitor in the market for exercise instructor licensing — was retracted by the Journal of Strength and Conditioning Research (JSCR) for improper IRB approval. Devor resigned from OSU the day after the first retraction.

Only one of the newly retracted papers had anything to do with the CrossFit study: Published in April 2014, this paper suggested that the so-called “paleo” diet — a diet focused on meat and vegetables — is associated with “unfavorable” changes in cholesterols and other blood-based cardiovascular biomarkers. In addition to following the diet, subjects also participated in a CrossFit exercise program. Continue reading Researcher who tangled with CrossFit loses two more papers

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
