‘All authors agree’ to retraction of Nature article linking microbial DNA to cancer

A 2020 paper that claimed to find a link between microbial genomes in tissue and cancer has been retracted following an analysis that called the results into question.

The paper, “Microbiome analyses of blood and tissues suggest cancer diagnostic approach,” was published in March 2020 and has been cited 610 times, according to Clarivate’s Web of Science. It was retracted June 26. The study was also key to the formation of biotech start-up Micronoma, which did not immediately respond to our request for comment.

Rob Knight, corresponding author and researcher at the University of California San Diego, also did not immediately respond to our request for comment.

Journal investigating follow-up study that didn’t mention patients had died

While presenting a paper in journal club, neurology resident at Baylor College of Medicine, Peter Campbell, noticed a potential problem. Two infants in a 2018 paper were reported to have died, but their data also appeared in a follow-up study published two years later with no mention of them being deceased.

“It is unclear how a patient who reportedly died could be available for follow-up at 2 years,” he wrote in an email reporting his concerns to Frontiers, the publisher of the articles. The email, sent in April, went unanswered.

Elsevier reopens investigation into controversial hydroxychloroquine-COVID paper

A March 2020 paper that helped spur the discredited claim hydroxychloroquine could treat COVID-19 is under investigation – again – after some of its authors asked to take their names off the article.

The lead author, retired researcher Didier Raoult, has 12 retractions, according to The Retraction Watch Database. Those retractions involved violations of ethics rules. Journals are investigating many other articles by Raoult and his colleagues, including their work on hydroxychloroquine as a treatment for COVID.

The paper, “Hydroxychloroquine and azithromycin as a treatment of COVID-19: results of an open-label non-randomized clinical trial,” was published in the International Journal for Antimicrobial Agents. It has been cited more than 3,000 times, according to Clarivate’s Web of Science.

Wiley journal retracts two papers it said were fine following criticism years ago

Two years after a journal told sleuths it wouldn’t retract flawed papers, it changed course and pulled them.

Mark Bolland, a researcher at the University of Auckland in New Zealand who is no stranger to unearthing academic wrongdoing, first sent complaints about one of the papers to The International Journal of Gynecology and Obstetrics (IJGO) in March 2021. He said the data on bone mineral density in “Isosorbide mononitrate versus alendronate for postmenopausal osteoporosis,” which has been cited 26 times according to Clarivate’s Web of Science, were “impossible.”

Bolland said the data the researchers reported were not consistent with the reference values provided by the maker of the device used to measure bone density in the study. The normal ranges are 0.96 +/- 0.12 g/cm², whereas the experiment reported much lower values of 0.21-0.24 g/cm².

In an email to Retraction Watch, Bolland’s colleague Andrew Grey called the data “laughable, frankly.”

‘Perplexed’ author’s identity forged on plagiarized paper in ‘probably fake’ journal

In February, Steffen Barra Googled his name. A clinician working in the field of forensic psychiatry, he was in the habit of periodically checking if anything negative had been written about him. What he didn’t expect to find was a plagiarized paper with his name attached to it.

Barra, a researcher at the University of Saarland in Germany, told us the 2023 article, “Introducing the Complexities of Forensic Psychology: Decoding the Mind Behind the Crime,” plagiarized from an information page from a company offering online courses. The article also resembles many college informational pages about the field, such as this one from the University of North Dakota, he said.

Concerned he might be blamed for the misconduct, Barra immediately contacted the publisher, Hilaris.

A company representative responded to Barra the same day, February 29, with one phrase: “We will remove the link.”

Two papers retracted for plagiarizing a 50-year-old thesis

A math professor in Poland has lost two papers because she plagiarized a doctoral thesis written before the United States had put a man on the moon.

The articles by Daria Michalik, “The decomposition uniqueness for infinite Cartesian products” and “Some remarks on the uniqueness of decomposition into Cartesian product,” published in 2017 and 2016, respectively, were retracted this year from Topology and its Applications over concerns they closely resembled an unpublished 1968 dissertation from Polish topologist Zbigniew Furdzik: “On the properties of certain decompositions of topological spaces into Cartesian products.”

Michalik has associations with the Institute of Mathematics, the same institution with which Furdzik, now deceased, earned his PhD. As of August of 2023, she was a researcher at Jan Kochanowski University in Kielce, Poland.

The retraction statements for both papers read:

Pharmaceutical researcher faked data in two papers, says federal watchdog

A former professor and vice provost for research at the Albany College of Pharmacy and Health Sciences in New York, falsified data in two published papers, according to findings from the U.S. Office of Research Integrity (ORI).

Shaker Mousa, who was also chairman and executive vice president of the Pharmaceutical Research Institute at Albany, already has at least 10 retractions and two corrections, by our count.

The falsified data appeared in “Tetraiodothyroacetic acid-conjugated PLGA nanoparticles: a nanomedicine approach to treat drug-resistant breast cancer,” which appeared in Nanomedicine in 2013, and “The proangiogenic action of thyroid hormone analogue GC-1 is initiated at an integrin,” which appeared in the Journal of Cardiovascular Pharmacology in 2005 and was retracted last September. ORI called for Mousa to request a correction or retraction of the Nanomedicine paper as well.

University vice president for research contests retraction for image issues

A university vice president has received his first retraction – and disagrees with it, according to the journal.

The retraction for Jaydutt Vadgama, the Vice President for Research and Health Affairs at the Charles R. Drew University of Medicine and Science, comes after a commenter on PubPeer noted similarities between data in two papers from the same group. Similar comments have led to corrections to two other papers by Vadgama, who is also professor at the David Geffen School of Medicine at University of California, Los Angeles.

The retracted article, “A83-01 inhibits TGF-β-induced upregulation of Wnt3 and epithelial to mesenchymal transition in HER2-overexpressing breast cancer cells,” appeared in Breast Cancer Research and Treatment in 2017. It has been cited 38 times, according to Clarivate’s Web of Science.

The retraction notice, published this month, states:
