Retraction Watch

Why has this microRNA review paper been cited more than 2,000 times?

Earlier this year, Marc Halushka, a pathologist at Cleveland Clinic in Ohio, came across a review titled simply “MicroRNA,” an unusually short title in a big field. Looking deeper into the review, published in the Journal of Allergy and Clinical Immunology in 2018, Halushka found it had been cited more than 2,000 times. He thought this number “shockingly high,” given the article’s brevity and content.

Other, older reviews on microRNA from leaders in the field have been cited far more often, some even tens of thousands of times. But when searching “microRNA” on Google Scholar, the review with that single term as its title is the first result.

Halushka doesn’t think anything in the paper is wrong or out of date. But the citation was among those in a paper he was asked to review that he thought “was clearly a paper mill paper,” he told Retraction Watch. He suspects when people “who know nothing about microRNAs because they are just in the paper mill business” need to cite a review on the topic, they just use the top search result.

Exclusive: Journal bans drug safety database papers as they flood the literature

Starting around 2023, a curious trend took hold in papers on drug safety monitoring. The number of articles published on an individual drug and its link to specific adverse events went from a steady increase to a huge spike.

The data source in most of those articles was largely the same: The FDA Adverse Events Reporting System, or FAERS. In 2021, around 100 studies mining FAERS for drug safety signals were published. In 2024, that number was 600, with more than that already published this year.

Two journals in particular published the bulk of these papers, Frontiers in Pharmacology and Expert Opinion on Drug Safety. In response to the flood, Frontiers started to require independent validation of studies drawing on public datasets. And Expert Opinion on Drug Safety decided in late July to stop accepting submissions altogether that use the FAERS database for this particular type of study.

Drummond Rennie (1936-2025), in his own words

I first became aware of the work of Drummond Rennie almost by accident: By borrowing his office. It was the summer of 1997, and as a rising fourth-year medical student, I was spending a month at JAMA as the co-editor-in-chief of its then-medical student section, Pulse. Rennie, who was deputy editor of the journal at the time, was mostly traveling, so the staff installed me in his office, overflowing with books and manuscripts.

Rennie, who died on September 12, was a towering figure in scientific publishing. Trained as a nephrologist, he joined the staff of the New England Journal of Medicine in 1977, and later, JAMA, where he remained for decades. He was known for promoting improved standards in medical journals, and for organizing the first Peer Review Congress, held in 1989 and nine more times since, most recently earlier this month.

In 2013, we were just a few years into the work of Retraction Watch, and thought talking about what we’d learned so far at the Congress would be a good idea. We submitted an abstract outlining what we wanted to talk about, writing that we’d gather data by the time of the meeting.

When you discover you’re an author on a paper you’ve never seen

Our list of retracted or withdrawn COVID-19 papers is up past 500. There are more than 60,000 retractions in The Retraction Watch Database — which is now part of Crossref. The Retraction Watch Hijacked Journal Checker now contains more than 300 titles. And have you seen our leaderboard of authors with the most retractions lately — or our list of top 10 most highly cited retracted papers? What about The Retraction Watch Mass Resignations List?

When you discover you’re an author on a paper you’ve never seen

Learning a paper with your name on it has been published is typically something to celebrate. But for one climate scientist, a recent notification was the first he learned the manuscript even existed.

So instead of rejoicing, Jan Cermak, a researcher at the Karlsruhe Institute of Technology in Germany, was busy writing to the journal Chemosphere about a paper he’d been credited with but never seen.

The paper, on meteorologic influences on air pollution in India, has been retracted after it became clear that a visiting fellow included Cermak as a coauthor without his permission.

University vice chancellor’s work crawling with ‘tortured phrases’

The chief executive of a university in Eastern India whose research is full of tortured phrases – possible signs of plagiarism – had two papers pulled in December after investigations found evidence of “compromised” peer review and other red flags in the publications.

A third article by the executive, Amiya Kumar Rath, has also come under scrutiny, a publisher told us.

Rath became vice chancellor of Biju Patnaik University of Technology in Rourkela in 2023. A computer scientist with more than 100 publications, he is listed as the second author of one of the now-withdrawn works, a 2020 review article on inspecting and grading fruits using machine learning.

Deputy department chair loses paper for image duplication, more retractions to follow

An Elsevier journal has retracted a paper coauthored by a deputy department chair at Thomas Jefferson University in Philadelphia and says it plans to retract at least two more of his articles for image-related concerns.

The 2022 paper, in Matrix Biology, describes the regulatory role of proteoglycans in remodeling of the cervix during pregnancy. According to the August 12 retraction notice, 18 of the image panels were duplicates. The paper has been cited 18 times, according to Clarivate’s Web of Science.

Renato Iozzo, deputy chair of Pathology, Anatomy & Cell Biology at Jefferson, is a coauthor on the study. Neither Iozzo nor corresponding author Mala Mahendroo, a researcher at UT Southwestern Medical School in Dallas, responded to our requests for comment.

‘Article broker’ in China trying to hook journal editors with fishy publishing deals

Earlier this year, China’s supreme court said companies selling fake or low-quality research papers should be punished. But shady middlemen there continue to offer questionable deals to journal editors across the globe in a bid to secure publications for their customers, emails obtained by Retraction Watch suggest.

In the emails, sent between May and August and using the same boilerplate language, the Nanjing-based agency A-Techo said it would pay an “expedited processing fee” of $500 to $1,000 US “per accepted manuscript to support the review process.”

According to its website, the company provides various types of publication support. Signatures in the correspondence we obtained listed different names of purported assistant editors, who said they were “writing on behalf of an academic institution that supports Ph.D. researchers and faculty in publishing high-quality research.”

Iraqi university dean linked to paper mills has more than a dozen retractions

A professor of pharmaceutical chemistry in Iraq has been steadily racking up retractions since 2022, with reasons ranging from authorship manipulation to irrelevant citations, peer review-by-author and not providing study data upon request.

Yasser Fakri Mustafa, who is also dean of the College of Pharmacy at the University of Mosul and editor-in-chief of the Iraqi Journal of Pharmacy, now has at least 16 retractions to his name, and more are likely to follow. One publisher told us it is actively investigating Mustafa’s work, and 81 of his more than 500 papers have been flagged on PubPeer.

From 2008 to 2019, Mustafa published no more than one or two articles a year, and often he had no output at all, according to the research database Dimensions. Then his output rose sharply, peaking at 120 in 2022, according to Dimensions. That same year, however, the researcher’s name appeared in a blog post by Nick Wise and Alexander Magazinov about authorship-for-sale networks. The two sleuths had found several papers by Mustafa and a slew of international coauthors that matched authorship ads on various websites, including that of a Russia-linked paper mill in Latvia, as they documented on PubPeer.
