BMJ corrects controversial critique of US dietary guidelines report

downloadThe BMJ has published a correction to a critique of the U.S. dietary guidelines report that has received heavy criticism from nutrition experts.

The author, journalist Nina Teicholz, has also posted a response to the criticism of the article.

The BMJ investigation, released in September, asserted that the guidelines committee used “weak scientific standards” to make its recommendations. It also criticized several aspects of the new expert report for the guidelines, such as “deleting meat from the list of foods recommended as part of its healthy diets.”

Soon after the feature appeared, The Verge — who first reported the news of the correction this week — called it “bogus.” The BMJ quickly issued a “clarification” to the paper, in the “rapid response” section of the paper (the journal’s version of a comment section). It noted that the feature should have specified “lean” meats.

The new, official, correction doesn’t formally put the clarification on the record. Instead, it addresses the research behind the analysis about saturated fats. Here it is in full:

Taste researcher falsified data in two papers: ORI

ori-logoA federal report has found that a former University of Maryland postdoc “falsified and/or fabricated” data in two papers about taste receptors.

The Office of Research Integrity report found that Maria C.P. Geraedts manipulated bar graphs in the papers to “produce the desired result.” Both have been retracted. Geraedts left academia in 2014, and is now a science writer.

We reported on one retraction in July, “Gustatory stimuli representing different perceptual qualities elicit distinct patterns of neuropeptide secretion from taste buds,” published in The Journal of Neuroscience.

The other, “Transformation of postingestive glucose responses after deletion of sweet taste receptor subunits or gastric bypass surgery,” published in 2012 in the American Journal of Physiology Endocrinology and Metabolism, was retracted in September. Here’s the note, which cites the university’s investigation: Continue reading Taste researcher falsified data in two papers: ORI

University investigating duplicated images in retracted paper

Cell MetabolismThe authors of a Cell Metabolism paper are pulling it after discovering blot images that “appear more than once in independent and unrelated experiments.” 

Just how the duplication occurred in the 2009 paper — about transcription of mitochondrial DNA — remains a mystery, the authors note:

…the reasons for the errors are still under investigation…

Meanwhile, we’ve learned that the last author on the paper — Carlos Moraes of the University of Miami — has requested a retraction for another 2013 paper in Mitochondrion, also co-authored by Tina Wenz at the University of Cologne in Germany. That paper is among multiple publications co-authored by Moraes and Wenz that have been flagged on PubPeer.

We’ve reached out to the parties involved, and received a warning from an attorney representing Wenz that if we write about Continue reading University investigating duplicated images in retracted paper

Symposium intro pulled after author refuses to revise following changes to lineup

Integrative and Comparative Biology

A biology journal has pulled the introduction to a symposium that was published online before the symposium papers had been finalized. After reviewers rejected multiple papers, the author of the introduction — and organizer of the symposium — refused to revise his portion accordingly, so the journal retracted it.

Suzanne Miller, an assistant editor at Integrative and Comparative Biology, told us that the journal ended up rejecting two out of the seven papers in the symposium. When editors asked the symposium organizer, Valentine Lance, to rewrite the introduction — which contained a brief background on each speaker — he told us that he refused to do the rewrite, and said that he “simply quit.”

Miller told us the journal is now changing its practice as a result of this incident: Continue reading Symposium intro pulled after author refuses to revise following changes to lineup

Correction restores confidence in results of confidence study

Strategic Management JournalA study that looked at how entrepreneurs’ confidence levels change depending on market conditions has been corrected to fix an error that flipped the results of one of the experiments.

The paper was published in 2013 by the Strategic Management Journal, and explored how entrepreneurs stay confident in difficult marketplaces by studying how people reacted to tasks of varying difficulty. In one experiment, participants were asked how well they thought they did on an easy quiz and how well they did on a hard quiz. Results showed that “participants underestimated their scores on the easy quiz” and “overestimated their performance on the difficult quiz.” However, authors wrote the opposite in the final paper.

Here’s the correction notice for “Making Sense of Overconfidence in Market Entry”:

Surgery journal publishes — then retracts — response to letter that never appeared

Annals of Surgery

How’s this for confusing: A surgery journal is retracting researchers’ response to a letter about their paper, because the letter was never actually published.

According to the managing editor of the Annals of Surgery, the letter — about a 2011 analysis of IV fluids in trauma patients — was accepted, prompting the journal to ask for a response from the authors of the 2011 paper. But the letter-writers never supplied required forms, such as conflict of interest. After spending two years trying to track them down, the journal decided not to publish the letter.

In the meantime, however, the authors’ response to the letter was “inadvertently published,” forcing the journal to retract it. Continue reading Surgery journal publishes — then retracts — response to letter that never appeared

Prostate cancer paper flagged by ORI is retracted following PETA prompt

cover_issue_129_en_USA federal investigation into a paper on prostate cancer has now led to a retraction. In an unusual twist, it happened following a request from the animal rights group People for the Ethical Treatment of Animals (PETA).

In January, the Office of Research Integrity reported that corresponding author Dong Xiao “intentionally fabricated data” in an Oncotarget study of how a steroid inhibits the growth of prostate cancer. Xiao, a former cancer researcher at the University of Pittsburgh, claimed that he had tumor data from more mice than he did, and falsified several figures.

In July, after no sign of the retraction, a researcher at PETA followed up with the journal, Oncotarget, on behalf of the organization “and our more than 3 million members and supporters to request the immediate retraction.”

Last month, they received a reply from the publisher, which they forwarded to us:

Mega-correction for “empirical anomalies” in management paper

The Academy of Management JournalThe author of a paper that looked at how the geographical spread of research and development sites has impacted innovation has posted a four-page list of corrections that fixed “empirical anomalies” in the paper.

A group of PhD students raised concerns about the paper’s findings, according to the editor-in-chief of The Academy of Management Journal, Gerard George. The journal formed a committee that worked with the author to reproduce the results. That ended with a correction to two of the paper’s three hypotheses, and corresponding parts of the text.

The four-page notice — (the details of which are paywalled, unfortunately) — includes notes from the journal’s editor and the author:

A retired obstetrics and gynecology professor under federal investigation for misconduct has notched his ninth retraction.

The latest retraction stems from an investigation by the University of Florida, where Nasser Chegini worked until 2012, which found fabricated data in three figures in a paper on the muscle cells that line the uterus.

The paper, “Differential expression of microRNAs in myometrium and leiomyomas and regulation by ovarian steroids,” was published in The Journal of Cellular and Molecular Medicine. It’s been cited 74 times, according to Thomson Scientific’s Web of Knowledge.

Here’s the note:

Activist group retracts warnings about midwest oil wells

downloadAfter receiving additional data from the government, an activist group has retracted an analysis that suggested energy companies were not taking steps to cut back on a controversial practice.

The Bakken analysis — named for North Dakota’s gigantic underground deposit of oil and natural gas — was published by the Environmental Law and Policy Center (ELPC). It focused on a practice known as “gas flaring” — burning natural gas instead of using or selling it. The analysis, released last month, found that hundreds of wells in North Dakota had not filed the necessary plans for saving excess gas produced in the course of extracting oil from wells. But after the Department of Mineral Resources provided more data — we’re not sure what kind of data, specifically — the ELPC retracted that conclusion.

The group posted the retraction notice on September 25, just four days after they presented the analysis at a news conference. It states why their recent evaluation of companies’ plans to capture excess gas might be wrong — and what they’re doing next:
