Two groups mistakenly publish case reports on the same patient

Journal of Clinical Pharmacy and Therapeutics

Talk about a popular patient: A woman who developed a case of internal bleeding while taking the anticoagulant Xarelto (rivaroxaban) was written up in not one — but two — case reports. The trouble was, both groups didn’t realize what the other was doing, so the more recent article is now being retracted from the Journal of Clinical Pharmacy and Therapeutics.

The authors, a trio of doctors at Sakarya University in Turkey, described the case of a 75 year-old woman who came to the emergency room for fatigue and stomach pain after taking rivaroxaban for three days. A scan revealed a rectus sheath hematoma.

However, the case had already been published a few months earlier in the Indian Journal of Pharmacology by a separate group of doctors from Sakarya, along with authors from Yenikent State Hospital and Vakfikebir State Hospital.

Sea squirt draft paper published by mistake

cover (1)

A paper on the evolution and development of urochordata — also known as sea squirts — was published in an under-developed form: Due to the publishers’ “error,” a “preliminary draft” of the article was published online in Developmental Dynamics last year.

The draft has been retracted; we can no longer find it on the site at all. The final copy of the paper has been posted in its place.

Here’s the retraction note in full for “Development, Metamorphosis, Morphology and Diversity: Evolution of Chordates muscles and the Origin of Vertebrates”:

Three more retractions for former record-holder Boldt, maybe more to come

m_cover

Justus Liebig University in Germany has been investigating concerns that Joachim Boldt, number two on the Retraction Watch Leaderboard and now up to 92 retractions, may have “manipulated” more data than previously believed.

Until now, the vast majority of Boldt’s retractions were thought to have involved inadequate ethics approval. However, new retraction notices for Boldt’s research suggest that there’s evidence the researcher also engaged in significant data manipulation.

The first retraction from the university investigation emerged last year. Two of three new notices cite the investigation specifically, and an informant at the university told us that there are more retractions to come.

Here are the retracted papers that are freshly on the record, starting with an August retraction for a 1991 Anesthesiology paper (cited 37 times, according to Thomson Scientific’s Web of Knowledge):

“Major overlap” forces retraction of osteoporosis paper

j adv nursThe Journal of Advanced Nursing has retracted a 2006 paper by a group of authors in Hong Kong who lifted much of the text from a previous article of theirs in a competing publication.

The article, “Osteoporosis prevention education programme for women,” came from Moon Fai Chan and C.Y. Ko in the School of Nursing at the Hong Kong Polytechnic University. Per the abstract:

To catch a cheat: Paper improves on stats method that nailed prolific retractor Fujii

anaesthesiaThe author of a 2012 paper in Anaesthesia which offered the statistical equivalent of coffin nails to the case against record-breaking fraudster Yoshitaka Fujii (currently at the top of our leaderboard) has written a new article in which he claims to have improved upon his approach.

As we’ve written previously, John Carlisle, an anesthesiologist in the United Kingdom, analyzed nearly 170 papers by Fujii and found aspects of the reported data to be astronomically improbable. It turns out, however, that he made a mistake that, while not fatal to his initial conclusions, required fixing in a follow-up paper, titled “Calculating the probability of random sampling for continuous variables in submitted or published randomised controlled trials,” also published in Anaesthesia.

According to the abstract:

Corrections (and one EoC) propagate for distinguished plant biologist, Olivier Voinnet

There may be some deeply rooted issues in the work of high-profile plant biologist Olivier Voinnet, biology department research director at ETH in Zurich. Corrections have continued to pile up months after his work was hit with a barrage of criticism on PubPeer. We’ve tracked a total of seven corrections over the past five months (not including the April retraction of a 2004 paper in The Plant Cell). One of the corrected papers also received an Expression of Concern this week.

Collectively, the corrected papers have accumulated more than 1200 citations.

In January, Voinnet said he planned to correct multiple papers, after receiving “an anonymous email.”

One of the recent corrections we found is for a 2003 article in The Plant Journal, “An enhanced transient expression system in plants based on suppression of gene silencing by the p19 protein of tomato bushy stunt virus,” which details using proteins from a tomato virus to help alter gene expression. The study has been cited 862 times, according to Thomson Scientific’s Web of Knowledge. Here’s the correction notice, posted June 8:

Two more retractions make four for bone researcher

JAnatBone anatomists have retracted two papers on primate jawbone structure from the Journal of Anatomy due to “errors in the validation protocol and data,” marking the fourth retraction for one of the authors.

Olga Panagiotopoulou retracted two other papers over the past year, all of which were due to a common methodological problem. As Panagiotopoulou — who completed the work in the UK, before joining the University of Queensland in Australia in 2013 —  explained to us in April,

Lost your data? Blame an earthquake

coverJNC

A natural disaster is to blame for a retraction about lethal brain tumors. At least, that’s where the authors say the problem started: with a 2010 earthquake that caused a loss of “substantial data.”

The paper, “Superoxide-dependent uptake of vitamin C in human glioma cells,” looks at how the cells of lethal brain tumors interact with the vitamin commonly used to reduce side effects of therapies.

Post earthquake, someone digitally filled in a western blot analysis of proteins from a cell line and rat brains, as a “temporary solution.” And then the temporary solution made its way into the Journal of Neurochemistry.

Here’s the retraction note from the journal, including an image of the sneaky western blot:

Article on suicide in Egypt retracted for double publication

JForensicSci_ak9A 2012 article published in the Journal of Forensic Sciences is being retracted because of an “overlap with a previous publication by the same authors.”

The corresponding author, Heba Yassa, a lecturer at Assiut University in Egypt, readily explained in an email exchange that the mix-up was due to a miscommunication with the editor of another journal, which she believed was not going to publish the article. “I know accidentally that the editor…published the article.”

The article, which examined suicides in one of the largest provinces in Egypt between 2005 and 2009, found rates had gone up since 1987, and men tended to use more violent methods than women.

Here’s the retraction notice: Continue reading Article on suicide in Egypt retracted for double publication

Third structure slip-up for chemist in Korea yields retraction

Chem_ak3Authors of a 2010 Chemistry – A European Journal article have retracted it “due to the wrong assignment of structure” of catalysts.

The retraction is the third, by our count, for corresponding author Doo Ok Jang, a chemist at Yonsei University in Wonju. Jang authored one of the previously retracted papers with Sung Jun Kim and the other with Sang Yoon Kim. Both papers were also sunk by misassigned structures.

The current study, “Enantioselective Radical Addition to Ketimines: A Synthetic Route Towards α,α-Disubstituted α-Amino Acids,” is authored by all three chemists. Here’s the retraction notice:
