“All co-authors are honorary:” Team earns fifth retraction

Movement DisordersA team of researchers from Japan has earned a fifth retraction, after co-authors told the journal that they did not participate in much of the paper.

Yoshihiro Sato, listed at Mitate Hospital, is the only author of the paper who was not “honorary,” the managing editor of the journal confirmed. He and the same co-authors recently lost three other papers about preventing hip fractures for “concerns regarding data integrity” and authorship issues — one of those papers, published in JAMA, specified that Sato was responsible for the data. All four authors were also included in a retraction last year of a paper with “concerns about the underlying data;” there, too, Sato said his co-authors were named “for honorary reasons.”

Here’s the retraction notice for “Alendronate and vitamin D2 for prevention of hip fracture in Parkinson’s disease: A randomized controlled trial,” published in Movement Disorders:

JAMA journals pull 3 papers by same authors for misconduct

JAMAJAMA and another journal in its network have retracted three 2005 papers about preventing hip fractures, after an admission of scientific misconduct. 

All papers are being retracted over concerns about data integrity, and “inappropriate assignment of authorship.” Four of the authors — all based in Japan — have co-authored all of the three newly retracted papers, and also share authorship of a previous retraction from 2015. 

The JAMA paper was tagged with an Expression of Concern last year, regarding the “conduct, integrity, and scientific validity” of the paper. 

Here’s the retraction notice for the JAMA paper, “Effect of Folate and Mecobalamin on Hip Fractures in Patients With Stroke:” Continue reading JAMA journals pull 3 papers by same authors for misconduct

Journals retracts three bone papers for duplication by same author

1-s2.0-S0168365907X02700-cov150hA journal is Journals are retracting three papers after a biomaterials researcher duplicated his own work, sometimes using the same figures to describe different experiments.

Two of the papers are on bone regeneration; one is about targeting tumors. In addition to issues with figures, two one of the retraction notes explain that the papers contain “widespread plagiarism of text” from other papers by the researcher, Hossein Hosseinkhani.

Hosseinkhani is currently affiliated with the National Taiwan University of Science and Technology; when he did the work in the now retracted papers, published in 2004 and 2007, he was based at Kyoto University Hospital and then National Institute for Materials Science in Japan.

The Journal of Controlled Release published all three two of the papers. Here’s the retraction note for “Bone regeneration through controlled release of bone morphogenetic protein-2 from 3-D tissue engineered nano-scaffold,” which has been cited 118 times, according to Thomson Scientific’s Web of Knowledge.

Lancet retracts 24-year-old paper by “father of nutritional immunology” after reopening inquiry

lancetFollowing questions from outside experts, a retraction of a related paper, a university investigation and a court case, The Lancet has decided to retract a 1992 paper by Ranjit Kumar Chandra, the self-proclaimed “father of nutritional immunology.”

In a lengthy retraction note included in the January 30 issue, the journal explains that:

the balance of probabilities in our judgment is that the reliability of the 1992 Lancet paper by Chandra can no longer be assured.

Chandra is objecting to the retraction.

This retraction was a long time coming, so sit back and relax as we fill in the backstory. Continue reading Lancet retracts 24-year-old paper by “father of nutritional immunology” after reopening inquiry

You’ve been dupe’d: Meet authors who like their work so much, they publish it twice

fertility and sterility

When our co-founders launched the site in 2010, they wondered whether there would be enough retractions to write about on a regular basis. Five+ years and three full-time staffers later, and we simply don’t have the time to cover everything that comes across our desk.

In 2012, we covered a group of duplication retractions in a single post, simply because duplications happen so frequently (sadly) and often don’t tell an interesting story. So in the interest of bookkeeping, we’re picking up the practice again.

Here are five unrelated retractions for your perusal: all addressing duplications, in which the same – or mostly the same – authors published the same – or mostly the same – information in two different – or sometimes the same – journals.

So, on the buffet table we offer the following entrees: Continue reading You’ve been dupe’d: Meet authors who like their work so much, they publish it twice

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:”

Plagiarized figure hurts arthritis paper

Screen Shot 2015-12-03 at 10.49.37 AM

A paper on a way to inhibit arthritis has been retracted following an investigation confirming that it plagiarizes a figure from another paper on the same topic.

The paper, “Blockade of 11β-hydroxysteroid dehydrogenase type 1 enzyme inhibits experimental collagenase-induced osteoarthritis,” was published in Molecular Medicine Reports. A figure claims to show cartilage treated with a specific inhibitor:

Osteoporosis paper felled by concerns with “scientific integrity”

cover (3)

A paper suggesting that exposure to sunlight might help prevent hip fractures in the elderly has been retracted, due to duplication and “concerns about the underlying data.”

An expression of concern that appeared last July flagged the 2005 paper as containing text that matched another paper with the same first author that was published in 2011. According to the publisher, that duplicated text sparked a closer look at the text, which raised concerns about the scientific integrity of the paper.

The retraction note, published by the Journal of Bone and Mineral Research, says that the first author was responsible for the content of the paper: Continue reading Osteoporosis paper felled by concerns with “scientific integrity”

Bone researcher manipulated data in JAMA study, says investigation

Screen Shot 2015-10-27 at 10.53.53 AMA bone researcher manipulated data in a 2011 JAMA study about an inexpensive treatment for osteoporosis. That’s the conclusion of an investigation at the researcher’s former workplace, the Women’s College Hospital in Toronto, the Toronto Star reports.

The study — led and manipulated by Sophie Jamal — followed 243 women over two years, as they applied nitroglycerin ointment once a day. The ointment is currently used to prevent chest pain and treat anal fissure pain by relaxing blood vessels; Jamal’s study concluded it could help patients with osteoporosis, too:

Among postmenopausal women, nitroglycerin ointment modestly increased [bone mineral density] and decreased bone resorption.

But even the modest effect was too good to be true. Continue reading Bone researcher manipulated data in JAMA study, says investigation

Three retractions for geriatric medicine researcher

Screen Shot 2015-08-20 at 11.51.11 AMA trio of papers on health issues in elderly patients, all sharing an author, have been retracted from Geriatrics & Gerontology International. 

The reasons for the retractions range from expired kits, an “unattributed overlap” with another paper, “authorship issues,” and issues over sample sizes.

Tomader Taha Abdel Rahman, a researcher at Ain Shams University in Cairo, is the first author on two of the papers, and second author on the third.

Here’s the retraction note for a paper that showed elderly adults with chronic hepatitis C are at risk of having cognitive issues:
