Another paper by Duke pair with 12+ retractions is flagged

American Journal of Respiratory and Critical Care MedicineAnother expression of concern (EOC) has appeared for a pair of lung researchers formerly employed by Duke University.

Co-authors Erin Potts-Kant, a research assistant who left the school and was charged with embezzlement, and Michael Foster, who has retired, share more than a dozen retractions, corrections and EOCs.

Like many of those papers, the American Journal of Respiratory and Critical Care Medicine is being flagged over concerns it is “unreliable.” Here’s more from the EOC:

JAMA takes all calls for retraction seriously — even from PETA

JAMAA leading medical journal is taking a second look at a recent high-profile paper about elephants’ lower risk of cancer, after receiving a call for retraction from a somewhat unusual corner: the animal rights group PETA.

This isn’t the first time the activist group has called for a retraction — last year, it nudged a journal to pull a paper that had been flagged for fraud by the U.S. Office of Research Integrity. Their latest target: A 2015 paper in JAMA, which PETA claims contains inaccurate information.

What’s more, the organization argues, Ringling Bros and Barnum & Bailey Circus — which partly funded the research — is using the findings as “justification for the continued use of abusive training techniques with elephants.” Yesterday, PETA sent a letter to the journal asking it to either retract the paper or issue an expression of concern, claiming: Continue reading JAMA takes all calls for retraction seriously — even from PETA

Epilepsy researcher gets retraction, correction after former colleague flags work

EpilipsiaEpilepsy researcher Toni Schneider has received a retraction and a correction in quick succession, after a former colleague raised red flags about the work. 

The retraction for Schneider, based at the University of Köln in Germany, is for “unintentional inclusion of erroneous data” due to limitations of the recording system used in the paper, according to the notice. 

Marco Weiergräber, a former colleague of Schneider’s, has claimed that the authors of the paper did not use the test properly. The journal editor, however, told us he believes the original analysis is an “honest mistake,” and there is “no evidence” to suggest that the authors intentionally published incorrect analyses.

Here’s the retraction notice, issued by the journal in March 2016: Continue reading Epilepsy researcher gets retraction, correction after former colleague flags work

Neuro journal pulls article for data theft, prompts misconduct probe

annneuro

Neuroscientists have retracted a research letter less than two months after it appeared, admitting they appeared to pass off others’ data as their own.

Two of the researchers are listed as affiliated with the University of California, San Francisco (UCSF), and the incident has led to a misconduct investigation at the institution, a UCSF spokesperson told us.

The article, “DNAJC6 variants in Parkinson’s disease and amyotrophic lateral sclerosis,” appeared in April. It was quickly followed by this notice, dated in May: Continue reading Neuro journal pulls article for data theft, prompts misconduct probe

Retractions aren’t enough: Why science has bigger problems

Andrew Gelman

Scientific fraud isn’t what keeps Andrew Gelman, a professor of statistics at Columbia University in New York, up at night. Rather, it’s the sheer number of unreliable studies — uncorrected, unretracted — that have littered the literature. He tells us more, below.

Whatever the vast majority of retractions are, they’re a tiny fraction of the number of papers that are just wrong — by which I mean they present no good empirical evidence for their claims.

I’ve personally had to correct two of my published articles.   Continue reading Retractions aren’t enough: Why science has bigger problems

In precedent break, BMJ explains why it rejected controversial “weekend effect” paper

After the reviewer of a rejected paper was publicly outed, the BMJ has taken the unusual step of explaining why it chose not to publish the paper.

The paper — eventually published in another journal — raised hackles for suggesting that there is no “weekend effect,” or a higher mortality rate in hospitals on Saturday and Sunday. This caught the attention of UK policy makers, who have proposed changing policies to compensate for any supposed “weekend effect.”

Amidst the heated discussion about the research, one of the reviewers was identified, along with suggestions that he may have been conflicted because he had published a study showing the opposite finding. Yesterday, the BMJ posted a blog explaining that it was the editors — and not one sole reviewer — who decided to reject the paper: Continue reading In precedent break, BMJ explains why it rejected controversial “weekend effect” paper

Researchers decry study warning of low-carb diet risks

Nutrition and DiabetesAdvocates of low-carbohydrate diet are voicing concern about a recent paper that suggested the diet could cause weight gain, contrary to previous research. One expert has even called for its retraction.

The study, published in Nutrition & Diabetes in February, also found that the low-carb diet did little to prevent the progression of type 2 diabetes. Researchers have since criticized the study for drawing these conclusions based on data from a handful of mice, using a poor proxy for the human version of the diet.

One expert took to social media to warn against the study’s message regarding the low-carb, high-fat diet (LCHF); for instance, obesity & nutrition researcher and author, Zoë Harcombe from Newport, Wales, tweeted: Continue reading Researchers decry study warning of low-carb diet risks

Stem cell researchers fix two papers following PubPeer comments

Screen Shot 2016-04-13 at 5.56.09 PMA pair of stem cell researchers have earned two corrections, the result of images that were mislabeled, distorted, or compiled incorrectly, according to the notices.

Kang Cheng prepared the gels when he was a research fellow in last author Sanjeev Gupta‘s lab at the Albert Einstein College of Medicine. Gupta told us he reviewed the original gels, and the errors didn’t affect the conclusions in the papers, which were reproducible. He noted he believes the problems are the result of honest mistakes:

The errors did not confer any benefits whatsoever either for the papers or for Dr. Cheng.

On PubPeer, commenters have raised questions about the now corrected papers — along with several others on which Gupta is the senior author, but Cheng is not a co-author.

Edward Burns, research integrity officer at Einstein, told us that the medical school looked into an allegation of misconduct against Gupta:

Does posting on PubPeer count as prior publication? Journal says yes, rejects letter rebutting campus sexual assault data

Jim Hopper

Journals typically shy away from publishing data and text readers have seen before — but amidst the newly established norms of open science and data sharing, what counts as a prior publication?

We’re asking ourselves that question after learning that JAMA Pediatrics has rejected a letter rebutting a recent study in the journal about sexual assault on college campuses after deciding that posting the letter on PubPeer is a prior publication.

The submitted letter (which you can read here) was co-authored by independent consultant, therapist and researcher Jim Hopper, who is also a Teaching Associate in Psychology at Harvard Medical School. It concerned a 2015 paper published in JAMA Pediatrics, which suggested that the long-held belief that most rapists on college campuses are repeat offenders may be false. The findings can have major implications for university efforts to stop assaults, as institutions weigh whether to divert resources towards punishment (if serial offenders are largely responsible) or prevention (if most men only commit assaults once).

Cell Press flags two papers after author confesses to fraud

Screen Shot 2016-04-11 at 8.45.56 PMNormally, when we see disputes over fraud allegations, it’s one author accusing another — but an unusual case at Cell has recently crossed our desk.

The journal has flagged a paper after an author confessed to committing fraud himself — but the corresponding author is disputing that confession, citing concerns about the confessor’s “motives and credibility.”

Independent labs are repeating the experiments to determine if the third author on the paper did, as he so claims, manipulate experiments. In the meantime, Cell and Molecular Cell have issued expressions of concern (EOCs) for two papers on which Yao-Yun Liang was a co-author. The notices cite an inquiry at Baylor College of Medicine, where the work was done, which was inconclusive, and recommended the journals take no action about the papers.

The EOCs are pretty much the same (both journals are published by Cell Press). Here’s the EOC that appears on “PPM1A functions as a Smad phosphatase to terminate TGFbeta signaling,” published in 2006 by Cell and cited 251 times, according to Thomson Reuters Web of Science:
