Costly genotyping mistake forces lab to pull 3rd paper

KPSB_11_09_COVER.inddA few months ago, an author alerted us to two retractions — including one in PNAS — after realizing his team had been using plants affected by inadvertent genotyping errors for an entire year. He initially told us these were the only two papers affected, but more recently reached out to say he had to pull a follow-up article, as well.

Recently, Steven C. Huber contacted us about the newest retraction, noting he was submitting a notice to the editor of Plant Signaling and Behavior:

Child psychiatrist flagged for misconduct loses two more papers

Mani PavuluriA child psychiatrist has lost two papers after an institutional investigation concluded that she intentionally misrepresented children’s medication history in her research.

In November 2015, we reported on a retraction for Mani Pavuluri in the Journal of Psychiatry & Neuroscience following a probe at the University of Illinois at Chicago, her institution, which concluded that there was a “preponderance of evidence” that Pavuluri had committed misconduct. 

After an “unanticipated event” took place during a study, three studies by Pavuluri were halted and a letter was sent out to 350 research subjects, informing them of errors in the work. At the time, the Illinois spokesperson noted that Pavuluri — who, according to her LinkedIn page, is a Distinguished Fellow of the American Academy of Child and Adolescent Psychiatry — was also asked to retract two 2013 studies in the Journal of Affective Disorders. Those papers have now been retracted, noting that Pavuluri “intentionally and knowingly” misrepresented children’s medication history.

Oh, well — “love hormone” doesn’t reduce psychiatric symptoms, say researchers in request to retract

psychiatry-research

It turns out, snorting the so-called “love hormone” may not help reduce psychiatric symptoms such as depression and anxiety.

At least, that’s the conclusion the authors of a 2015 meta-analysis, which initially found intranasal doses of oxytocin could reduce psychiatric symptoms, have now reached. After a pair of graduate students pointed out flaws in the paper, the authors realized they’d made some significant errors, and oxytocin shows no more benefit than placebo.

First author Stefan Hofmann from Boston University in Massachusetts explains further in a lengthy letter he sent to Psychiatry Research, which he passed on to us: Continue reading Oh, well — “love hormone” doesn’t reduce psychiatric symptoms, say researchers in request to retract

Does dose matter? Tumor killer paper thought so, now must retract

Molecular Medicine ReportsAfter questions from a reader, researchers took a second look at their data about the effects of a vitamin A metabolite on tumor cells, and realized their key finding was inaccurate.

They’re now retracting the paper, from Molecular Medicine Reports, because it originally reported that higher concentrations of retinoic acid (RA) were more effective in curbing the proliferation of brain tumor cells. But it seems that the RA dose made less of a difference than they originally believed, according to the retraction notice:

Where was chem research conducted? Not here, say two of three listed author affiliations

ChemosphereA researcher has retracted two 2016 papers after discovering problems with the data that negated the findings — and after one of his three listed affiliations denied the research was conducted there.

According to the retraction notices issued by Chemosphere, Hong-Wei Luo incorrectly claimed to be affiliated with the Oak Ridge National Laboratory (ORNL) in Tennessee in one of his three affiliations. His other institutions listed on the papers include universities in Singapore and China.

However, an official from the Nanyang Technological University (NTU) in Singapore, told us the work in the now-retracted papers was not carried out at the NTU either.

Here’s the first of the retraction notices, issued on August 8: Continue reading Where was chem research conducted? Not here, say two of three listed author affiliations

Doing the right thing: Authors pull psych review after finding inaccuracies

Two psychology researchers are retracting a meta-analysis after discovering errors they believe may affect the conclusions.

We’re giving this a “doing the right thing” nod, as last author Pankaj Patel of Villanova University in Pennsylvania contacted us about his plan to retract the paper, and resubmit for publication once he and co-author Sherry Thatcher — at the University of South Carolina — have performed all their recalculations.

Here’s the retraction notice for “Demographic faultlines: A meta-analysis of the literature,” published in the Journal of Applied Psychology: Continue reading Doing the right thing: Authors pull psych review after finding inaccuracies

Second retraction for bone researcher with lifetime funding ban

A researcher banned from funding by a Canadian agency for misconduct has earned her second retraction, after a reanalysis uncovered problems with the paper’s conclusions.

The retraction follows an investigation by Sophie Jamal‘s former workplace, the Women’s College Hospital in Toronto, which has led to a recent retraction of a JAMA paper due to data manipulation, and a lifetime funding ban from the Canadian Institutes of Health Research (CIHR).

The latest retraction stemmed from a re-analysis of the paper by the Canadian Multicentre Osteoporosis Study Group, of which the paper was a part; all authors but Jamal have requested the retraction. In the notice, the authors say that they believe no patients were harmed as a result of the “possibly invalid conclusions” in the paper, which showed patients with kidney problems were at higher risk of bone loss. A researcher told us a third paper by Jamal is also due to be retracted soon.

Here’s the retraction notice, issued by the American Journal of Kidney Diseases (AJKD): Continue reading Second retraction for bone researcher with lifetime funding ban

Nutrition study pulled after statistical flaws emerge

Nutrition JournalA paper that suggested that eating flaxseed could reduce inflammation in men at risk of heart disease has been retracted, after researchers pointed out the paper’s flaws.

The retraction is part of a large initiative on the part of nutrition researcher David Allison and colleagues to clean up the literature, which we’ve previously covered. Regarding this paper, he told us:

When we looked at the study…it was very clear that the statistical methods used were not correct. These are not matters of debate or opinion, these are just…verifiably incorrect.

The Nutrition Journal published the paper in January 2015, and retracted it in June 2016, one day after publishing a letter by Allison and a colleague critiquing the paper. 

Here’s the retraction notice for “Impact of weight loss diet associated with flaxseed on inflammatory markers in men with cardiovascular risk factors: a clinical study:” Continue reading Nutrition study pulled after statistical flaws emerge

Journal taking second look at paper on campus rape

violence and genderA journal is reviewing a paper about trends in rape at U.S. colleges after the author realized a mistake.

Although the journal Violence and Gender hasn’t issued any editorial notice about the paper, Inside Higher Ed published a correction July 14 to its original news story about the topic.

“Dangerous Colleges: Associations Between School-Level Factors and the Risk of Sexual Victimization of Female Students” found that the risk of rape was higher at large, public institutions, but after the author realized he had made a coding error, he contacted Inside Higher Ed to explain that the risk of rape was higher only at public universities, regardless of their size.

The paper appeared in the June, 2016 issue of the journal; Sophie Mohin, Assistant Managing Editor for publisher Mary Ann Liebert, told us the author alerted the journal to the mistake on July 12: Continue reading Journal taking second look at paper on campus rape

The corresponding author of the 2016 study that found high levels of the carcinogen formaldehyde leaking from a prominent British artist’s exhibition is now retracting it.

The study, about Damien Hirst’s 2012 exhibition at the Tate Gallery in London that presented dead animals embalmed in glass cases full of formaldehyde, suggested that higher than recommended limits of the carcinogen were being released from the exhibition. The study was widely covered by the media, which raised concerns over possible health hazards to visitors.

As we reported yesterday, the journal Analytical Methods had already issued an expression of concern (EOC), noting that the corresponding author of the paper, Pier Giorgio Righetti of the Polytechnic University of Milan in Italy, warned the paper may contain unreliable data.

Today, Righetti released a joint statement with Hirst’s company, Science Ltd, stating that he will be retracting the paper (reported earlier today by the New York Times). It reads:   Continue reading Author to retract study warning of toxic leaks from Damien Hirst’s artwork
