Embattled journal Cureus delisted from Web of Science, loses impact factor

Clarivate has removed the mega-journal Cureus from its Master Journal List, according to the October update, released today

The move means Cureus will no longer be indexed in Web of Science or receive an impact factor. As we have reported, it can also mean researchers are less likely to submit to the journal, given universities rely on such metrics to judge researchers’ work for tenure and promotion decisions.

Clarivate put indexing for the journal on hold last September for concerns about article quality, which the journal has been criticized for in the past.

Exclusive: Journal to retract Alzheimer’s study after investigation finds misconduct

A journal says it will retract a 2019 paper on an Alzheimer’s treatment after an institutional investigation found research misconduct, according to emails seen by Retraction Watch. The move comes four years after another investigation by the same university uncovered image duplication in a different paper by a similar group of authors.

The paper, published in Biological Psychiatry, describes the potential of an apoE antagonist for treatment in Alzheimer’s disease. 

A 2019 news release by the University of South Florida, home to several of the researchers involved in the study, called the work “promising.” Lead author Darrell Sawmiller, an assistant professor at USF, said the study represented “the first time … we have direct evidence” apoE “acts as an essential molecule” in the mechanisms leading to Alzheimer’s.

Controversial Paxil “Study 329” earns expression of concern after critic sues publisher

After more than 20 years of criticism and calls for retraction, a journal has placed an expression of concern on a study of the antidepressant Paxil in teens that critics say has led to unwarranted and potentially harmful prescribing of the drug to youth. 

The 2001 paper, published in the Journal of the American Academy of Child & Adolescent Psychiatry (JAACAP), reported findings from a randomized trial known as “Study 329,” which concluded the antidepressant Paxil was safe and effective in kids ages 12 to 18. 

In 2012, Paxil maker GlaxoSmithKline agreed to pay $3 billion to settle civil and criminal charges that included “unlawful promotion” of the drug for adolescents, for whom the product was never approved, and allegations the company “participated in preparing, publishing and distributing a misleading medical journal article” — the JAACAP paper.  A reanalysis in 2015 found the drug was “ineffective and unsafe” for the age group studied.

Sleuth loses paper for duplicate publication after flagging hundreds of untrustworthy articles

A sleuth who has identified several hundred articles describing clinical women’s health research with untrustworthy data, leading to nearly 300 retractions, has now lost one of his own papers for duplicate publication. 

Ben Mol, who leads the Evidence-based Women’s Health Care Research Group in the department of obstetrics and gynecology at Monash University in Australia, has worked to raise awareness of problematic data informing medical recommendations for women’s health care, and to cleanse the literature of unreliable studies, with major media outlets covering his work. 

Mol told Retraction Watch about 50 of his papers have been investigated since 2020, usually after anonymous complaints. “It is clear that somebody had been screening my papers … in a systematic way to find any wrongdoing,” he said. His only other retraction came after he and colleagues found an error in their own work and requested the action.

Duke scientists lose eight papers for alleged image manipulation

Salvatore Pizzo

Eight papers by two emeritus researchers from Duke University have been retracted in recent months for alleged image duplications. Although the researchers had worked at the university for decades, Duke officials have not responded to repeated inquiries about the retractions. 

The papers were published between 2004 and 2014 in The Journal of Cellular Biochemistry and PLOS One. According to the retraction statements, the articles contained images and figures that appeared similar or identical to others in the same paper or published elsewhere. 

The two researchers, Salvatore Pizzo, a former chair of Duke’s Department of Pathology, and his colleague Uma Kant Misra, spent much of their careers studying prostate cancer.  From 1993 to 2015, Pizzo and Misra published 70 papers together, with 26 where they are the only authors. Pizzo did not respond to repeated emails from Retraction Watch asking for comment. Misra died Sept. 18

Authors defend retracted paper on vitamin D and COVID-19 called ‘deeply bizarre’ by critic

PLOS One has retracted a paper linking vitamin D levels and COVID-19 morbidity three years after a critic flagged the data in the study as “deeply bizarre.” The authors objected to the retraction, with one calling it “outrageous” and pointing to flaws in the published notice.

The article, which appeared in February 2022, claimed people with low levels of vitamin D were at increased risk for severe COVID-19 and were more likely to die of the disease than other patients. It has been cited 65 times, according to Clarivate’s Web of Science. 

The paper had a “huge, immediate impact,” said Gideon Meyerowitz-Katz, a senior research fellow from the University of Wollongong in Australia, citing the fact that the paper had been viewed over 1 million times within six weeks of being published. The article joins others, many also flagged by Meyerowitz-Katz, purporting to find links between vitamin D intake and COVID-19 severity that have been retracted or removed.

Study on apple cider vinegar for weight loss retracted after many raise concerns

Easy fixes for complex health problems can be tempting — but they rarely pan out. That seems to be the case for the investigators on one clinical trial who claimed consuming apple cider vinegar caused obese teens and young adults to lose weight. 

Their article appeared in March 2024 in BMJ Nutrition, Prevention & Health. The journal is retracting the paper “because the authors’ analyses could not be replicated and multiple errors were identified,” according to the retraction notice.

The retraction, dated September 23, comes more than a year after sleuths pointed out some of these errors and other problems with the analysis.

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.

Embattled journal Cureus halts peer reviewer suggestions

The mega-journal Cureus is eliminating author suggestions for peer reviewers, a prompt that is standard practice at some journals when submitting a manuscript. 

According to an email sent August 25 to current and past peer reviewers, the move is “due to the potential conflict of interest” that comes from authors suggesting reviewers who may be mentors and colleagues. 

Reviewers recommended by authors are more likely to give positive feedback on papers. And such recommendations gave way to such practices as peer review rings and self-peer review, vulnerabilities that started to thrive more than a decade ago
