Non-retraction notice: Editors explain why two similar papers aren’t redundant

abdominal radiologyEditors have published a notice to let readers know why they’re not retracting a couple of papers.

One paper examined whether the results of CT scans could be used to stage patients with uterine carcinoma; the other considered whether CT scans could be used to predict overall survival in uterine carcinoma. Both papers — by researchers at the Memorial Sloan Kettering Cancer Center — used data from the same 193 women. After they appeared in in different journals, the editors considered whether they were redundant — a quality that can spell retraction for a paper.

The editors explain why they decided the papers were unique in a brief commentary — a non-retraction notice, if you will — published in a third journal, Abdominal Radiology:

Materials journal breaks three papers from the same author

Metals and Materials Journal.

Metals and Materials International has retracted three papers from one author, due to suspicions of plagiarism and authorship issues.

The three papers have one thing in common — the same lead author, Reza Haghayeghi from the Islamic Azad University in Tehran, Iran.

The retraction notices — all released in March, 2016 — lead with the following:

Seven more retractions for anti-terrorism prof brings count to 15

MemonAnti-terrorism researcher Nasrullah Memon has notched seven more retractions, bringing his total up to 15 — earning him a spot on our leaderboard.

We previously reported on eight pulled papers authored by Memon, based at the University of Southern Denmark in Odense. There was some confusion over whether his count then increased to nine — but, following a retracted retraction, his total was back to eight.

Now, it seems like the retracted retraction has been re-retracted, and six other of Memon’s publications have been pulled. Memon has also been found guilty of plagiarising his PhD thesis, and more of his work is being questioned online.

The retraction notices for the newly pulled material — all published by Springer — include the following statement: Continue reading Seven more retractions for anti-terrorism prof brings count to 15

Study on pregnant women with HIV lied about having ethics approval

Screen Shot 2016-04-12 at 5.47.50 AMWe recently discovered a relatively old retraction notice — from 2014 — of a study on pregnant women with HIV.

The paper was retracted two years ago when BMC Research Notes discovered the authors falsely claimed they had obtained ethics approval from an institution in Kenya.

The study looked at the effectiveness of an antiretroviral therapy in 50 women who were receiving care at a center in Nairobi, Kenya. But the authors did not have permission from the center to use data from the women, nor the necessary ethics approval from Moi University to carry out the work.

Here’s the retraction note for “Effectiveness of option B highly active antiretroviral therapy (HAART) prevention of mother-to-child transmission (PMTCT) in pregnant HIV women:”

Peer review scam leader now up to 20 retractions

Khalid Zaman
Khalid Zaman

We’ve unearthed four more retractions for Khalid Zaman, an economist who lost 16 papers in 2014 for orchestrating fake peer review.

That brings Zaman’s total to 20, and ties him at the #18 spot on our leaderboard.

One of the more recently discovered retractions is for fake peer review, attributed to Zaman; one is for plagiarism, and two other papers were withdrawn while in press, for reasons that are unclear. (Note bene: These retractions are all at least one year old.)

First, the retraction notice for peer review issues, published in April 2015 for “Environmental Indicators and Energy Outcomes: Evidence from World Bank’s Classification Countries:”

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:

How much does a retracted result pollute the field?

Research Integrity and Peer Review

When a paper is retracted, how many other papers in the same field — which either cite the finding or cite other papers that do — are affected?

That’s the question examined by a study published in BioMed Central’s new journal, Research Integrity and Peer Review. Using the case of a paper retracted from Nature in 2014, the authors found that subsequent research that cites the retracted paper often repeats the problematic finding, thereby spreading it throughout the field. However, papers that indirectly cited the retracted result — by citing the papers that cited the Nature paper, but not the Nature paper itself — typically don’t repeat the retracted result, which limits its spread.

Here’s how the authors describe their findings in the paper: Continue reading How much does a retracted result pollute the field?

Plant biologist’s paper pulled for falsification, three more questioned on PubPeer

PMBP Cover ImagePhysiology and Molecular Biology of Plants has retracted a paper about using Darjeeling tea clones against abiotic stress for problems with one of the figures.

The specific problem: “falsification/fabrication” of data underlying the figure, which the corresponding author — Sauren Das from the Indian Statistical Institute in Calcutta, West Bengal — couldn’t resolve. Das told us he denies the allegations made by the journal.

Meanwhile, three other papers by Das have been questioned on PubPeer

Let’s take a look at the retraction note: Continue reading Plant biologist’s paper pulled for falsification, three more questioned on PubPeer

Journals retract two heart papers with “nearly identical” abstracts

Screen Shot 2016-02-22 at 4.46.17 PMJournals have retracted two papers after realizing that they contain “nearly identical” abstracts and introductions, published only months apart. 

The two retracted papers, along with a third that also contains similar text, all conclude that a certain polymorphism could signal a risk for coronary artery disease among Chinese people, though each paper presents different data. The papers do not have any authors in common; the first authors are all based at different hospitals in China. The editor in chief of one journal told us that some of the reviewers did not use institutional email addresses, which leaves open the possibility that they were fake emails, and the peer-review process was compromised.

Here’s the first retraction notice, for “Fibroblast growth factor receptor 4 polymorphisms and susceptibility to coronary artery disease,” published in DNA and Cell Biology. The notice states the paper contains:

How did two papers on same gene with different authors, publishers, end up with identical retraction notices?

1-s2.0-S0006291X16X00058-cov150h1Here’s an interesting case: We’ve found two retracted papers that describe the same gene, and both have nearly identical retraction notices. What’s unusual is that the two papers don’t have any authors in common, and appeared in two different journals published by two different companies.

The cause of both papers’ demise: Plagiarism, and use of unpublished data without permission “from an unnamed source,” who wishes to remain that way. The author of one of the papers confirmed to us that the unnamed source is a “3rd party service company.” Springer told us that the third party in the other paper, however, is another researcher.

It’s a puzzling case, to be sure. We think we have uncovered some of what happened, but remain slightly fuzzy on the details.

Here’s the first retraction, for “KDM3A interacted with p53K372me1 and regulated p53 binding to PUMA in gastric cancer,” originally published online September 30 by Biochemical and Biophysical Research Communications:
