PLOS ONE retracts paper after researcher admits to fabricating data

On June 19, 2017, the U.S. Office of Research Integrity published its first misconduct finding of the year. The ORI reported that Brandi M. Baughman — a former research training awardee at the National Institute of Environmental and Health Sciences (NIEHS) — had “falsified and/or fabricated data” in 11 figures in a 2016 paper published in PLOS ONE.

Two days later, on June 21, PLOS ONE retracted the paper. (Note: The retraction process proceeded relatively quickly, but took longer than two days; a spokesperson for the journal told us that the authors alerted the editors of their concerns about the publication in May.)   Continue reading PLOS ONE retracts paper after researcher admits to fabricating data

Uni dings schizophrenia studies for problems with informed consent, other flaws

Psychiatry journals have retracted two papers evaluating a schizophrenia drug after a university in Japan flagged issues, such as a lack of written informed consent.

The papers—published in Human Psychopharmacology: Clinical & Experimental in 2012 and Psychiatry and Clinical Neurosciences in 2014—examined the safety and effectiveness of an antipsychotic drug in patients with schizophrenia.

According to the retraction notice in Psychiatry and Clinical Neurosciences, the ethics committee at St. Marianna University School of Medicine in Kawasaki found that “the trial included subjects who did not satisfy inclusion criteria.” For instance, not all patients provided written informed consent. But the university found no evidence for data falsification or fabrication.

A spokesperson for Human Psychopharmacology told us: Continue reading Uni dings schizophrenia studies for problems with informed consent, other flaws

Following uproar, surgery journal retracts paper with male-only pronouns

The Annals of Surgery has retracted a paper that used only male pronouns to describe surgeons following outcry from readers.

The journal plans to replace the article — a recent presidential address of the European Surgical Association — with a new version with more “gender inclusive language.”

The problem, said editor Keith D. Lillemoe, is that the address was delivered in April by previous ESA president Marek Krawczyk in Polish. According to an email Krawczyk sent to ESA leadership, which Lillemoe forwarded to us, Krawczyk says the pronoun “his” can include women in Polish.

Still, Lillemoe told us, the journal believed it needed to quickly retract the paper:

Work by group at Australian university faces scrutiny

A journal is investigating research by a group in Australia, after receiving “serious allegations” regarding a 2017 paper about treating eye burns.

The journal, Frontiers in Pharmacology, has issued an expression of concern (EOC) for the 2017 paper while it investigates. The notice does not specify the nature of the allegations.  Meanwhile, several other papers by the three researchers, based at Deakin University in Geelong, Australia, have also come under scrutiny. Late last month, Frontiers in Pharmacology retracted a 2015 paper by Kislay Roy, Rupinder Kanwar, and Jagat R Kanwar, citing image duplication. A 2015 paper in Biomaterials received a correction in May 2017, again flagging image duplication.

Roy, the first author on the papers, is a postdoctoral research fellow; Rupinder Kanwar, a middle author, is a senior lecturer; and Jagat R Kanwar, the corresponding author on all three, is head of the Nanomedicine-Laboratory of Immunology and Molecular Biomedical Research.

Gearóid Ó Faoleán, the ethics and integrity manager at Frontiers in Pharmacology, explained that the investigation into the flagged article is ongoing and the EOC “must serve as the extent of our public statement for the present.”

A spokesperson for Deakin University declined to comment on the allegations: Continue reading Work by group at Australian university faces scrutiny

Jumped the gun: Paper about non-finalized guidelines is retracted

Too soon? A surgeon is retracting his overview of new hernia surgery guidelines after it was published before the guidelines were finalized.

The paper, published in German in the journal, Der Chirurg, was also retracted because — according to two co-authors of the new guidelines — the final version of the guidelines was supposed to appear first, in English, in another journal.

The author of the paper, Dirk Weyhe, explained that the journal invited him to write an overview of the new guidelines for a special issue. According to Weyhe, a surgeon based in Germany who was a co-author on the guidelines, the aim of the special issue was to follow-up on an agreement reached at an international hernia conference in 2016: Continue reading Jumped the gun: Paper about non-finalized guidelines is retracted

“We do not want to create false hope”: Authors retract Cell paper they can’t replicate

A few years ago, researchers in Sweden had something to celebrate: They thought they had discovered a chink in the armor of the most common type of malignant brain cancer.

In a 2014 Cell paper, the team — led by Patrik Ernfors at the Karolinska Institutet — reported that they had identified a small molecule that could target and kill glioblastoma cells — the cancer that U.S. Senator John McCain was just diagnosed with — and prolong survival in mice with the disease. 

Satish Srinivas Kitambi, the paper’s first author, who is also based at the Karolinska Institutet, said the results got the team “really excited:” Continue reading “We do not want to create false hope”: Authors retract Cell paper they can’t replicate

NIH neuroscientist up to 19 retractions

The string of apparent bad luck continues for Stanley Rapoport.

Rapoport, a neuroscientist based at the U.S. National Institute on Aging, has lost three more papers in three journals due to the misconduct of his co-authors. By our count, these retractions bring his tally to 19 — and tie him for 21st place on our leaderboard.

The journals—Schizophrenia Research, Journal of Affective Disorders, and Biological Psychiatry— retracted the papers because the National Institutes of Health had found that one of Rapoport’s co-authors, Jagadeesh Rao, had “engaged in research misconduct by falsifying data.” Rao was corresponding author on all three papers.

According to a spokesperson for Elsevier, which publishes the journals, the Schizophrenia Research paper was retracted in July, the JAD paper in late May and the Biological Psychiatry paper in late April. The spokesperson told us that the publisher first received an email from the NIH about the misconduct findings on September 20, 2016, and that: Continue reading NIH neuroscientist up to 19 retractions

Diabetes researcher who sued to prevent retractions now has 13

A diabetes researcher who sued a publisher to protect several papers from being retracted recently received his 13th, in a prestigious gastroenterology journal.

Mario Saad, based at the University of Campinas in São Paulo, Brazil, has had a string of retractions over the past few years, including four in Diabetes after he lost a legal battle with the American Diabetes Association.

The latest retraction appears in Gastroenterology, citing possible image duplication. Saad is second-to-last author on the 2012 paper.

According to the retraction notice, the journal investigated data in several figures, and believes some were duplicated. The authors explained that the duplications resulted from inadvertently using wrong blots; still, the editors chose to retract the paper after determining they no longer had confidence in its conclusions.  

Here’s the retraction notice for “Obesity-Induced Increase in Tumor Necrosis Factor-α Leads to Development of Colon Cancer in Mice:” Continue reading Diabetes researcher who sued to prevent retractions now has 13

Volunteer researcher faked weeks’ worth of data

A volunteer researcher at Florida Atlantic University fabricated the results of mouse experiments over a 14-day period in June, 2016, according to a new finding issued by the U.S Office of Research Integrity (ORI).

According to the ORI, Alec Mirchandani made up the results of behavioral experiments to make it seem as if he had done the work, and falsified animal transfer logs, which affected research supported by the National Institute of Mental Health.

More specifically, the ORI determined that Mirchandani had “knowingly and intentionally:”

Authors say patient threatened legal action after being subject of scholarly paper

A patient appears to have had a change of heart about being featured in a case report.

The patient cannot be identified in the paper published in Journal of Gastrointestinal and Liver Diseases. However, according to the retraction notice, she threatened to sue if the authors did not withdraw it. After receiving the threat, the paper’s corresponding author, Mariano Sica, told us that the authors immediately asked the journal to retract the paper.

We’ve written about similar cases where patients do not provide informed consent or withdraw it, but in this case we haven’t seen the threat ourselves.

We asked Sica if we could see the legal threat, and he said he couldn’t share it, explaining: Continue reading Authors say patient threatened legal action after being subject of scholarly paper
