A once-lauded researcher in the field of infectious disease — who has since been found guilty of misconduct — has retracted a second paper.
Last year, the University of Dundee in Scotland investigated and ultimately concluded that Robert Ryan — whose work focused on infections that can be deadly in people with lung diseases such as cystic fibrosis — had committed “serious research misconduct,” affecting multiple publications. After appealing the decision, Ryan resigned.
We covered his first retraction earlier this month, which cited multiple instances of image duplication. Now Ryan has retracted his second paper, published in 2011 in Journal of Bacteriology, also due to image problems.
When journals learn papers are problematic, how long does it take them to act?
We recently had a chance to find out as part of our continuing coverage of the case of Anil Jaiswal at the University of Maryland, who’s retracted 15 papers (including two new ones we recently identified), and has transitioned out of cancer research. Here’s what happened.
As part of a public records request related to the investigation, we received letters that the University of Maryland sent to 11 journals regarding 26 “compromised” papers co-authored by Jaiswal, four of which had been retracted by the time of the letter. The letters were dated between August and September 2016 (and one in February) — although, in some cases, the journals told us they received the letter later. Since that date, three journals have retracted nine papers and corrected another, waiting between four and six months to take action. One journal published an editorial note of concern within approximately two months after the university letter.
And six journals have not taken any public action.
Late last year, Carl Ronald Kahn—also chief academic officer at Joslin Diabetes Center—retracted two papers for similar reasons. In November, Kahn pulled a 2005 paper from The Journal of Clinical Investigation (JCI) and a month later, he retracted a 2003 paper from The Journal of Biological Chemistry (JBC), both times citing duplications that the authors said were introduced while assembling the figures.
Last month, Kahn retracted his third paper, also published in JBC in 2003, because the authors omitted data when constructing the images. Still, the authors remain confident in their findings, given that data from other labs “have confirmed and extended the conclusions of the manuscript.”
Last summer, a journal retracted another paper by the pair, also citing suspicions of image manipulation. The latest batch of retractions — issued by seven different journals — includes some papers that have been questioned on PubPeer.
Dibyendu Talukdar, listed at the University of Calcutta in West Bengal, India, is the sole author on three retracted papers. He shares five new retractions with Tulika Talukdar listed at the University of North Bengal. That brings their totals to nine and six, respectively. (We’re not sure if the Drs. Talukdar are related).
We’ll start with the papers they share: Read the rest of this entry »
A new record: Major publisher retracting more than 100 studies from cancer journal over fake peer reviews
Springer is retracting 107 papers from one journal after discovering they had been accepted with fake peer reviews. Yes, 107.
To submit a fake review, someone (often the author of a paper) either makes up an outside expert to review the paper, or suggests a real researcher — and in both cases, provides a fake email address that comes back to someone who will invariably give the paper a glowing review. In this case, Springer, the publisher of Tumor Biology through 2016, told us that an investigation produced “clear evidence” the reviews were submitted under the names of real researchers with faked emails. Some of the authors may have used a third-party editing service, which may have supplied the reviews. The journal is now published by SAGE.
The retractions follow another sweep by the publisher last year, when Tumor Biology retracted 25 papers for compromised review and other issues, mostly authored by researchers based in Iran. With the latest bunch of retractions, the journal has now retracted the most papers of any other journal indexed by Clarivate Analytics’ Web of Science, formerly part of Thomson Reuters. In 2015, its impact factor — 2.9 — ranked it 104th out of 213 oncology journals.
Here’s more from Springer’s official statement, out today:
A few months ago, a researcher told Evelien Oostdijk there might be a problem with a 2014 JAMA study she had co-authored.
The study had compared two methods of preventing infection in the intensive care unit (ICU). But a separate analysis had produced different results.
Oostdijk, from the University Medical Center Utrecht in The Netherlands, immediately got to work to try to figure out what was going on. And she soon discovered the problem: The coding for the two interventions had been reversed at one of the 16 ICUs. This switch had “a major impact on the study outcome,” last author Marc Bonten, also from the University Medical Center Utrecht, wrote in a blog post about the experience yesterday, because it occurred at “one of the largest participating ICUs.”
When Oostdijk and a researcher not involved in the study analyzed the data again, they discovered a notable difference between the revised and original findings: The new analysis revealed that one of the interventions had a small but significant survival benefit over the other.
Oostdijk and Bonten, who supervised the re-analysis, notified their colleagues of the revised study outcomes and contacted the journal requesting a retraction and replacement, which was published yesterday in JAMA.
According to the notice of retraction and replacement:
A journal has flagged a paper by a researcher who has questioned the safety of genetically modified organisms, after receiving concerns that there were issues with some images.
In the 2006 paper, researchers led by Federico Infascelli, an animal nutrition researcher at the University of Naples, tested the blood of rabbits fed genetically modified soybeans. Starting in November 2015, however, the journal animal fielded concerns that gels appeared manipulated, and a figure legend differed from that in a thesis associated with the research.
This isn’t the first notice issued for Infascelli’s controversial work, which has been under scrutiny in recent years, including by Italian senator and biologist Elena Cattaneo. Last year, he was formally reprimanded by the University of Naples for including manipulated data in three papers.
Although the University of Naples concluded the image manipulations were “not a breach of scientific integrity,” the journal has issued a lengthy expression of concern about the paper:
The troubles continue for a bone researcher, who’s lost multiple papers in recent months due to problems ranging from data issues to including authors without their consent.
Now, journals have retracted two more papers by Yoshihiro Sato. And in a sign of the downstream effects that fraud can have, another journal has retracted two meta-analyses by other authors that cited his work.
Earlier this month, the journal Current Medical Research and Opinion retracted the two meta-analyses because they were based on recently retracted papers by Sato, affiliated with Mitate Hospital. The two new retractions of Sato’s papers are a review and a randomized controlled trial.
Sato was not an author on the meta-analyses published in 2008 and 2011; he was, however, first and lead author on all the retracted papers referenced in the notices. The notices state that the trio of authors on the meta-analyses:
According to the most recent retraction notices, issued by Applied Surface Science, the four papers duplicated several figures and portions of text from the authors’ previous works. Although the notices do not single out a responsible party, last year the Mumbai Mirror reported that first and corresponding Naba K. Sahoo had been accused of duplication by colleagues at the Bhabha Atomic Research Centre (BARC), part of Indian government’s Department of Atomic Energy.
(In a bizarre twist, Sahoo also made the news recently for getting into a fist fight with another BARC scientist.)
Sahoo received two retractions last year for duplication, sometimes inelegantly referred to as “self-plagiarism.” All six of his retractions affect papers published by Applied Surface Science between 2005 and 2007.
A researcher has threatened to sue publisher Taylor & Francis for mentioning a misconduct investigation into his work in a retraction notice.
According to the notice, the publisher retracted a 2008 paper and a book chapter after learning about a misconduct investigation into the work of Mark Jackson, a department head and endowed chair, respectively, at universities in Kansas.
Unfortunately, we don’t know much about the nature of the misconduct investigation; Jackson told us he initiated the retractions after raising concerns his colleagues had violated intellectual property. He has since told the publisher he would take legal action if it didn’t remove the phrase noting that the retractions stem from a misconduct investigation into his work from the notice.
Here’s the notice, issued by Materials Science and Technology:
