BMC investigating allegedly copied paper

logoBioMed Central is investigating a recent paper about a potential biomarker for liver cancer, which shows signs it was written using another article as a template.

According to Jeffrey Beall, who exposed the similarities between the two papers on his blog Scholarly Open Access yesterday, the paper in question is “obviously bogus,” and appears to have relied on the “template plagiarism” technique of creating a new article by modifying a previous paper’s text and data.

A spokesperson for BioMed Central, which published the allegedly “junk” paper, as Beall calls it, told us they are looking into the allegations: Continue reading BMC investigating allegedly copied paper

Authors retract second study about medical uses of honey

Journal of Clinical NursingA paper that tested the clinical value of honey on venous ulcers has been pulled by the Journal of Clinical Nursing after an investigation uncovered “errors in the data analysis.” Last year, the authors pulled another paper on the healing properties of honey on wounds. 

We just discovered this second retraction, which appears in the September 2015 issue of the journal, but was posted online last year.

The journal’s editor-in-chief, Debra Jackson, confirmed the dates and said that “a commercial company” brought the matter to their attention. After the journal asked a statistician to weigh in, they stated that a “substantial re-write would be required to correct the article,” and a retraction would be “the most suitable course of action.”

Although she said the authors initially sought to correct, not retract, the study, they eventually agreed with the decision.

Here’s the notice:

Diederik Stapel retraction count updated to 57

stapel_npcWe’ve learned about two more retractions we missed for Diederick Stapel, the Dutch social psychology researcher who has now racked up a total of 57 retractions by our count.

Both retractions were issued after a committee released a report which established fraud in dozens of papers co-authored by Stapel.

Stapel is still #4 on our leaderboard.

“Insufficient permission” from funder resects liver disease paper

HepatologyA study on chronic liver inflammation was pulled from the journal Hepatology because of “insufficient permission by the authors’ funding institution to submit and publish the manuscript.” 

The paper, which was published in July, looked into how steatosis, the abnormal retention of fat in the liver, turns into steatohepatitis, also known as fatty liver disease. Researchers found that Treg cells play a central role in controlling the disease.

Unfortunately, the journal’s managing editor didn’t provide any information about the nature of the permission problems, and the notice doesn’t give any details.

Here it is, in full:

Failure to reproduce key experiments retracts cancer study

Medical OncologyA group of Chinese cancer researchers has retracted a paper in Medical Oncology after they discovered that “several key experiments” were not reproducible.

The paper, “Decreased Warburg effect induced by ATP citrate lyase suppression inhibits tumor growth in pancreatic cancer,” was published in March. It found that suppressing the enzyme ATP citrate lyase could be used to treat pancreatic cancer.

However, the authors decided to pull the paper when some of the findings couldn’t be reproduced. 

Here’s the notice:

Author appeals retraction for plagiarism in clinical research paper

Journal of Human Reproductive SciencesThe first author of a paper that discussed sample sizes in clinical research is appealing the journal’s decision to retract it for plagiarism, arguing the article is “entirely different.”

The  Journal of Human Reproductive Sciences‘s editor-in-chief told us that they first contacted the author about the allegations more than two years ago, and finally issued the notice in September, saying the paper “directly copied” from another article on randomization. “Thus owing to duplicity of text, the article is being retracted,” according to the notice.

That doesn’t jibe with first author K. P. Suresh, based at the National Institute of Veterinary Epidemiology and Disease Informatics in India. He told us that the “two articles are entirely different concept.” In subsequent emails, he added Continue reading Author appeals retraction for plagiarism in clinical research paper

Journal mistakenly publishes Parkinson’s case report twice

Journal of Movement Disorders

A journal has retracted a duplicate version of a case report about a patient with Parkinson’s disease after mistakenly publishing the paper twice.

The Journal of Movement Disorders initially published the report — which detailed the case of an elderly woman with Parkinson’s disease whose symptoms worsened during drug treatment — in 2010. But it ended up printing it again in 2011 because of “a mistake of the editorial office and the publisher.”

The notice reads:

Authors defend publishing clinical trial six times, even as they earn two more retractions

Screen Shot 2015-09-30 at 12.14.06 PMIn August, we reported on a clinical trial on hundreds of hypertensive patients that was published six times. Now, copies published in Expert Opinion on Drug Safety and Journal of the American Society of Hypertension (JASH) have been retracted, making for a total of three retractions for the group of papers.

The authors have defended the papers as being decidedly “different,” but one of the latest retraction notes points to an earlier retraction by some of the same authors (including first author Giuseppe Derosa, at the University of Pavia in Italy) for publishing two papers that “contain considerable text that is duplicative.”

Inflammation editor in chief Bruce Cronstein, who retracted one of the six duplicated papers from the clinical trial, told us in August that he and the editors of the other journals were all contacted “en masse” by an author doing a Cochrane Review on hypertension, who noticed that all six papers were “nearly identical.”

Just recently, we received a statement from the authors — sent by corresponding author Derosa — which argued that even if six papers stem from one trial, each was decidedly “different:”

Boldt’s retraction count upped to 94, co-author takes legal action to prevent 95th

Screen Shot 2015-09-16 at 12.12.13 AM

We’ve found two recent retractions and an expression of concern for Joachim Boldt, former prominent anesthesiologist and currently Retraction Watch leaderboard’s 2nd place titleholder. He now has 94 retractions.

One of the retracted articles contains falsified data, along with a researcher who didn’t agree to be a co-author, according to an investigation by the Justus Liebig University Giessen, where Boldt used to work. The expression of concern is regarding some questionable data. The other new retraction is actually one of 88 papers that a group of editors agreed to retract back in 2011, after they were “unable to verify” approval by the Institutional Review Board (IRB) for the studies.

One of those 88 papers, we’ve discovered, has still has not been retracted. According to an editor at the journal, they haven’t removed it because one of Boldt’s co-authors has threatened them with legal action. Continue reading Boldt’s retraction count upped to 94, co-author takes legal action to prevent 95th

Image issues force retraction of liver transplant papers

ajtranspA group of researchers in Hong Kong and China have lost a pair of papers on liver transplantation after concerns were raised about the “origin of images” in the two studies.

The articles appeared in the American Journal of Transplantation in January and February of 2006, and came from the lab of S. T. Fan, of the University of Hong Kong. When the authors were asked about the images, they “were unable to satisfactorily mitigate the concerns.”

According to this bio from the journal Hepatobiliary Surgery and Nutrition, Fan: Continue reading Image issues force retraction of liver transplant papers
