Data sleuth flags 30 randomized clinical trials from researcher in Egypt

Ben Mol

Thirty randomized clinical trials involving a researcher in Egypt who has already had six papers retracted show signs of research misconduct and data fabrication, according to the authors of a recent preprint

Ben Mol, one of the authors of the preprint and a professor of obstetrics and gynecology at Monash University in Australia, has spent several years investigating the work of Sherief Abd-Elsalam, a hepatologist and gastroenterologist at Tanta University in Egypt. Abd-Elsalam denies that his research is false or fabricated. 

Mol has been exposing research misconduct in his own field for years. His work revealed dozens of dodgy obstetrics papers by Ahmed Badawy and Hatem Abu Hashim of Mansoura University, in Egypt, as well as serious problems with clinical trials led by Ahmed Maged at Cairo University, research about c-sections also from Cairo University, and urology research by Iranian researcher Mohammad Reza Safarinejad. 

Abd-Elsalam said in an email that he disagrees with the allegations in the preprint. “Where is the problem? We don’t know,” he wrote.

February: ‘we don’t agree there is an issue here.’ June: Retracted.

Rady El-Araby

A Springer Nature journal has retracted a paper on hepatitis C infection it had previously corrected for problematic data – but in between the editors declared the case closed.

The paper, “The interaction between microRNA-152 and DNA methyltransferase-1 as an epigenetic prognostic biomarker in HCV-induced liver cirrhosis and HCC patients,” was published in July 2019 in Cancer Gene Therapy. The authors were affiliated with Al-Azhar University, in Cairo, and the Ministry of Scientific Research, in Gizah, Egypt.  

Some two years later, Alexander Magazinov – a data sleuth about whom we’ve written beforeposted concerns on PubPeer about the article and three other papers by members of the group.

Frustrated by a university’s lack of action, a journal retracts

Expression of concern, meet expression of frustration.

Eight months ago, in the wake of skepticism about the data in a 2017 paper it had published, the Obstetrics & Gynecology issued an EoC about the article. At the time, the journal, an official title of the American College of Obstetricians and Gynecologists, said it had contacted the authors’ institution — Menoufia University in Shibin Al Kawm, Egypt — about the article.

Those efforts evidently met with silence. Now the journal has retracted the paper, “Sildenafil citrate therapy for oligohydramnios: a randomized controlled trial,” with a swipe at the school’s apparent lack of interest in the misdeeds of its faculty members:

“Questioned as implausible:” Journal retracts paper because a researcher claimed to perform a large clinical trial single-handedly

Is it possible for just one researcher to perform a clinical trial of more than 200 participants?

According to the editorial board of the European Journal of Obstetrics & Gynecology and Reproductive Biology, an Elsevier title, the answer would seem to be no. The journal has decided to retract a 2016 paper in which the author claimed to have conducted such a large trial on their own.

Here’s the notice for “Calcium versus oral contraceptive pills containing drospirenone for the treatment of mild to moderate premenstrual syndrome: A double blind randomized placebo controlled trial:”

“This is something that we have never seen before in any study:” Group loses two more papers

A group of rheumatology researchers in Egypt that lost a paper in 2016 for a variety of problems has lost two more.

The authors common to the two papers, Anna Abou-Raya and Suzan Abou-Raya, are based at the University of Alexandria, which did not find evidence of scientific misconduct, according to one of the retraction notices. The journal that published the two papers, The Journal of Rheumatology, however, found several other issues that led them to retract the papers.

Among them was that for one of the studies to have proceeded as described, all 125 subjects would have had to been enrolled and randomized on a single day: Continue reading “This is something that we have never seen before in any study:” Group loses two more papers

Author duplicated a figure in three papers; two get retracted

Two journals have retracted two papers by the same group within months of each other, after editors were independently tipped off that they contained duplicated figures representing different experiments.

The two papers were published by PLOS ONE and The Egyptian Journal of Biochemistry and Molecular Biology (EJBMB) in 2015 and 2014, respectively. According to the PLOS ONE paper’s corresponding author, last author Saad A. Noeman from Tanta University in Egypt used the same Figure 1 in both papers, along with another 2013 paper in EJBMB.

Corresponding author Yasser S. El-Sayed, head of the Department of Forensic Medicine and Toxicology at Damanhour University in Egypt, told us he learned of this issue after a reader brought the figure manipulation and duplication concerns to PLOS ONE’s attention.

El-Sayed said that he tried to figure out what had happened.

Nightmare scenario: Text stolen from manuscript during review

A food science journal has retracted a paper over “a breach of reviewer confidentiality,” after editors learned it contained text from an unpublished manuscript — which one of the authors appears to have reviewed for another journal.

The publisher and editors-in-chief of the Journal of Food Process Engineering became aware of the breach when the author of the unpublished manuscript lodged a complaint that his paper, under review at another journal, had been plagiarized by the now retracted paper.

We’re hazy on a few details in this case. Although the journal editor told us the “main author” of the retracted paper reviewed the original manuscript for another journal, the corresponding author of the retracted paper said he was not to blame. (More on that below.)

When looking into the matter, the publisher found that one of the co-authors of the published paper had acted as a reviewer of the unpublished manuscript. Alexandra Cury, an associate editor at Wiley, explained: Continue reading Nightmare scenario: Text stolen from manuscript during review

Journals pull two papers after blogger shares plagiarism suspicions

Journals have retracted two papers after they were flagged by a pseudonymous blogger, who suspected all had copied text from other sources.

What’s more, a third paper seems to have simply disappeared from the journal’s website, after the blogger, Neuroskeptic, alerted the journal to the text overlap.

Neuroskeptic became suspicious about the three unrelated papers – about food chemistry, heart disease, and the immune system and cancer – after scanning them with plagiarism software. After alerting the journals, two issued formal retractions for the papers – but neither specifies plagiarism as the reason.

The retractions were the result of a larger project, Neuroskeptic told us:

Sting operation forces predatory publisher to pull paper

Medical Archives

Sometimes, the best way to expose a problem with the publishing process is to put it to a test — perhaps by performing a Sokal-style hoax, or submitting a paper with obvious flaws.

In 2014, that’s just what a researcher in Kosovo did. Suspicious that a journal wasn’t doing a thorough job of vetting submissions, she decided to send them an article of hers that had already appeared in another journal. Her thinking was that any journal with an honest and thorough peer review process would hesitate to publish the work. But this journal didn’t — at least at first. Though they retracted the paper this summer, it took a few twists and turns to get there.

The researcher wasn’t the only one wary of the journal — it’s on Jeffrey Beall’s list of “potential, possible, or probable” predatory publishers. Appropriately, Beall recounts the story of her sting operation on his blog. Here’s how it all went down:

Author of retracted math paper defends against plagiarism charge, threatens to sue journal

A researcher in Egypt is threatening to sue a mathematics journal if it doesn’t un-retract one of his papers.

The American Journal of Computational Mathematics in May retracted Mostafa M. A. Khater‘s 2015 paper, “The Modified Simple Equation Method and Its Applications in Mathematical Physics and Biology.” The retraction notice is sparse on the details, indicating only that the article was not up to snuff: Continue reading Author of retracted math paper defends against plagiarism charge, threatens to sue journal
