Retraction published for nutrition researcher Marion Nestle

journal_pubhealthFollowing her request last month, a public health journal has retracted a paper co-authored by prominent nutrition researcher Marion Nestle, after revelations of multiple factual errors and her co-author’s ties to one of the subjects of the article.

The article, an opinion piece, critiqued the supposed relationship between the biggest beverage distributor in Guatemala and the leading Guatemala-based public health organization, to distribute a fortified supplement (Manì+) for undernourished children. The relationship, the piece argued, raised concerns about the conflicts of interest that can occur when a food company pairs with a public health organization. But soon after publication, Nestle learned that she and her co-author Joaquin Barnoya had misrepresented that relationship, and failed to disclose that the public health organization was paying a portion of Barnoya’s salary.

Here’s the full retraction notice, published earlier this month by the Journal of Public Health Policy: Continue reading Retraction published for nutrition researcher Marion Nestle

Neuroscience paper retracted after colleagues object to data publication

frontiersA paper published this October in the journal Frontiers In Neuroscience was retracted the following month because the authors’ collaborators did not give them permission to publish some of the data.

The paper detailed how and why the authors use the software program Nengo to test large simulations of nervous system networks. As part of the research, the authors tested five systems, one of which they were working on with another group. Due to a “miscommunication,” the authors thought they had received permission to publish the data; they plan to resubmit a paper describing the other four systems.

Here’s the official retraction note: Continue reading Neuroscience paper retracted after colleagues object to data publication

Stem cell researcher that sued Harvard failed to disclose conflicts on 6 publications

Piero Anversa, a stem cell researcher who we recently learned is leaving Harvard and Brigham & Women’s Hospital after suing them, has added a disclosure statement to six publications.

The four papers and two letters were published in Circulation, and all bear identical corrections:

Piero Anversa, MD, discloses that he is a member of Analogous, LLC.

The author regrets this omission.

Trouble is, we can’t find a company by that name. What we do know:

Author retracts statements about gay conversion therapy

Screen Shot 2015-12-17 at 1.49.17 PM

Key assertions in a paper on homosexuality have been removed from the Journal of the Islamic Medical Association of North America, in what the notice describes as a “partial retraction.”

The 2006 article “Homosexuality: An Islamic Perspective,” states that conversion therapy can be effective, and that gay people have poorer health. Those statements are among those that lack evidence, according to a note on the paper published in July. The retraction pulls those assertions, among others, and instead argues that a homosexual person should be helped to “accept his or her LGB identity,” and find a welcoming community.

The 2006 article is definitely a perspective — it states the opinion of the sole author, M. Basheer Ahmed, who has a private psychiatry practice in Texas, as to whether homosexuality is a choice. He thinks yes, though the science on the matter is fairly clear that it’s not.

But we still think it’s interesting that a journal chose to take back some of the statements contained in the article. Here’s the abstract from the “partial retraction” note:

Paper pulled when authors backtrack on identifying mad cow disease in Texas

Journal food protectionA journal is pulling a paper that reported a grain sample in Texas tested positive for mad cow disease after the authors asked to change the results to say the sample contained “animal protein prohibited for use in ruminant feed.”

Shortly after the paper was published in October, the authors contacted the Journal of Food Protection to retract the finding that the grain sample tested positive for bovine spongiform encephalopathy (BSE). After review, the journal decided to retract the entire paper, with the authors’ agreement, citing changes that “significantly affect” the findings.

JFP scientific editor Lauren Jackson filled us in on some details: Continue reading Paper pulled when authors backtrack on identifying mad cow disease in Texas

JAMA retracts osteoporosis paper with manipulated data

Screen Shot 2015-12-29 at 10.48.49 AMA JAMA study on an inexpensive treatment for osteoporosis has been retracted because the first author falsified or fabricated data. We’ve been expecting this one: An investigation at Women’s College Hospital in Toronto, the bone researcher’s former workplace, had already revealed issues with the paper.

An internal memo sent to staff (available in full here) in October explained that the investigation had found “unequivocal evidence of systematic data manipulation” by Sophie Jamal, who had already resigned from her positions at WCH and the University of Toronto.

The study appeared to show that nitroglycerin ointment could have a small positive effect on bone mineral density in postmenopausal patients. It’s been cited 30 times, according to Thomson Scientific’s web of Knowledge. (That’s two more times than when we last reported on the paper: It was cited once by the investigation, and once by a paper that was published earlier in October, but had not yet been indexed.)

Here’s the retraction note for “Effect of Nitroglycerin Ointment on Bone Density and Strength in Postmenopausal Women: A Randomized Trial:”

Here are the top 10 most highly cited retracted papers, ranked

RWEver wondered which retracted papers had the biggest impact on their fields?

We’ve compiled a list of the 10 most highly cited retracted papers. Note that many papers — including the #1 most cited paper — received more citations after they were retracted, which research has shown is an ongoing problem.

Readers will see some familiar entries, such as Continue reading Here are the top 10 most highly cited retracted papers, ranked
