The European Respiratory Journal (ERJ) is retracting a paper about whether mothers with asthma are more likely to have poor birth outcomes, after the journal found it overlapped with an earlier paper by the same group. The ERJ paper was published online on June 18, 2010.
The retraction notice said only that Continue reading Nearly identical twins: European Respiratory Journal retracts asthma in pregnancy paper similar to another by same group
A leading Japanese virologist has received a 10-year publishing ban from the American Society of Microbiology after many of his published articles were found to have evidence of data manipulation.
In its January 2011 issue, Infection and Immunity, an ASM title, is retracting five articles by the researcher, Naoki Mori, of the University of Ryukyus in Okinawa. The articles, published between 2000 and 2009, involve work on Helicobacter pylori which Nori conducted with co-authors from the United States and elsewhere. Some of the studies listed co-authors from drug companies, including Merck and Boehringer Ingelheim, although it’s not clear whether the companies helped support any of the research.
Despite the impending holidays, Ferric Fang, editor of Infection and Immunity, graciously and quickly replied to our request for comment yesterday (as he has before, about another paper in Nature involving fraud): Continue reading Japanese virologist hit with publishing ban after widespread data manipulation
It’s a mind-boggling story: A United Airlines pilot claims to be a cardiologist and was eagerly sought after for medical conferences at which he taught doctors teamwork. He shared millions in grants, according to the Associated Press. But as the AP reports, William Hamman wasn’t a cardiologist at all, having never even finished medical school.
Hamman’s career seems to be collapsing, now that he resigned from his post as a researcher and educator at Royal Oak, Michigan’s William Beaumont Hospital once the hospital found out he had misled them. (Just last year, Beaumont touted a $150,000 grant Hamman nabbed with a colleague, Marc Abramson at Improbable Research notes.) United has also grounded him.
The storyline is reminiscent of 2002’s Catch Me If You Can, in which Frank Abagnale Jr. (played by Leonardo DiCaprio) forges millions of dollars’ worth of checks around the world, in the process impersonating a Pan Am pilot and a doctor. In Hamman’s case, there are apparently no questions over whether his pilot credentials are legit, according to the AP.
Our interest at Retraction Watch is what happens to the papers Hamman has published over the years. There are at least six, including two published this year. The AP reported that Continue reading Catch Me If You Can: What happens to fake cardiologist William Hamman’s published papers?
It’s fair to say that we haven’t heard the last of Anil Potti, the Duke cancer researcher who resigned last month following revelations that he had faked some of his results. Duke is still investigating the situation, and has also asked the Institute of Medicine to conduct its own study into the case and its ramifications.
This week, we may find out whether Nature Medicine will retract a paper that Joseph Nevins, one of Potti’s co-authors, asked the journal to withdraw last month. We’re also keeping an eye on two other papers that have already been the subject of increased scrutiny: Continue reading More on Anil Potti: Two other papers worth keeping an eye on
Thrombosis and Haemostasis has issued an “expression of concern” over a 2004 paper by Tunisian researchers:
Concerns have been raised by readers about the accuracy and validity of the data reported in the September 2004 article by Abdelkefi et al., entitled “Prevention of central venous line-related thrombosis by continuous infusion of low-dose unfractionated heparin, in patients with haemato-oncological disease. A randomized controlled trial” (Abdelkefi A et al.Thromb Haemost 2004; 92: 654–661).
In the trial, 108 patients with blood cancers reportedly received infusions of either saline or heparin, a blood thinner. Those given the active drug were far less likely to develop clots related to their catheters, according to the researchers, and no more likely to experience severe bleeding. In the report, the researchers write:
This is the first prospective, randomized study, which shows that low-dose of unfractionated heparin is safeand effective to prevent catheter-related thrombosis in patients with haemato-oncological disease.
The article has had an impact, having been cited 32 times, according to Thomson Scientific’s Web of Knowledge. At some point after publication, however, the results evidently began to look fishy. Again from the journal: Continue reading Our computer ate the data: Expression of concern over blood thinner study raises concerns itself
Although some readers evidently have yawned at revelations that Vahdettin Bayazit, of Alparslan University in Turkey (and, we are tempted to assume, at least a few of his co-authors) appears to have plagiarized wantonly in numerous published articles, one follower of Retraction Watch was on to this case even before we were.
In an e-mail, the tipster laid out a picture of intellectual dishonesty audacious for both its scope and ham-handedness. The researcher, who wanted to remain anonymous, used Google to detect instances of plagiarism, just as we had, coming up with “more than 10” papers with passages stolen from the scientific literature and even Wikipedia, including not only lifted text but figures, too. And, just as in our case, the editors our source contacted about the misconduct have essentially ignored it.
We confess that we’re puzzled by the attitude that a little plagiarism is no big deal. As physician Andrew Burd writes in the BMJ today: Continue reading Sultans of swap: List of plagiarized papers grows to include BMJ
The Bosnian Journal of Basic Medical Sciences has retracted a paper it published in August by Turkish researchers on the potential cancer risks associated with exposure to electromagnetic fields, or EMFs.
The reason: Other people wrote nearly all of it.
According to an editor’s notice: Continue reading Sultans of swap: Turkish researchers plagiarized electromagnetic fields-cancer paper, apparently others
Joachim Boldt, a leading German anesthesiologist who had a 2009 paper in Anesthesia & Analgesia retracted last month* amid allegations that he had misrepresented parts of the study, has been relieved of his duties as chief physician at Ludwigshafen Hospital.
A press release from the German Society for Anesthesiology and Intensive Care Medicine (DGAI) condemns Boldt’s actions. The press release goes on (translated from German): Continue reading After misrepresentation allegations, German anesthesiologist Joachim Boldt out as hospital’s chief physician
Self-plagiarism alert: A very similar version of this post is being published online in Anesthesiology News, where one of us (AM) is managing editor.
If a plagiarist plagiarizes from an author who herself has plagiarized, do we call it a wash and go for a beer?
That scenario is precisely what Steven L. Shafer found himself facing recently. Shafer, editor-in-chief of Anesthesia & Analgesia (A&A), learned that authors of a 2008 case report in his publication had lifted two-and-a-half paragraphs of text from a 2004 paper published in the Canadian Journal of Anesthesia.
A contrite retraction letter, which appears in the December issue of A&A, from the lead author, Sushma Bhatnagar, of New Delhi, India, called the plagiarism “unintended” and apologized for the incident. Straightforward enough.
But then things get sticky. Continue reading Plagiarists plagiarized: A daisy chain of retractions at Anesthesia & Analgesia
Anil Potti, who resigned from his post at Duke today during an investigation into faked results, will likely have another retraction to his credit shortly. According to a Duke statement:
Dr. Potti’s collaborator, Joseph Nevins, Ph.D., has initiated a process intended to lead to a retraction request regarding a paper previously published in Nature Medicine. This process has been initiated due to concerns about the reproducibility of reported predictors, and their possible effect on the overall conclusions in this paper. Other papers published based on this science are currently being reviewed for any concerns. Continue reading Another update on Anil Potti: Co-author asks Nature Medicine to retract paper
