Journal that “suffered” from plagiarism purges itself

pharmpractWhen Pharmacy Practice found out it had been victimized by plagiarists, it apparently took the news personally — and to heart.

In an elaborate statement with more than a dozen references — but not one to the plagiarizing work — the journal lashed out against the behavior of word thieves, and described the discovery as a Road to Damascus moment.

Here’s the notice, which was published in 2012 but was only just indexed on PubMed:

Diabetes researchers retract, correct and republish study on mortality rates

diabetologiaA diabetes paper that received quite a bit of media attention when it was published in June 2013 was retracted and reissued to fix data errors shortly after publication.

The paper, which showed a steep decline in mortality rates for diabetics in Ontario, Canada, and the UK between 1996 and 2009, was republished in December 2013, with the same conclusion and the errors corrected.

Here’s the retraction notice for “Mortality trends in patients with and without diabetes in Ontario, Canada and the UK from 1996 to 2009: a population-based study”: Continue reading Diabetes researchers retract, correct and republish study on mortality rates

Second study of widely touted cancer and HIV “cure” retracted

j med virologyLast month, we brought you the story of the retraction of a paper by Nobutu Yamamoto and colleagues about “a protein being used — unapproved by health agencies — to treat diseases including cancer and autism.”

A second paper by the group, about using the protein to treat HIV, has been retracted. Here’s the notice for “Immunotherapy of HIV-infected patients with Gc protein-derived macrophage activating factor (GcMAF),” from the Journal of Medical Virology:

Sampling the wrong part of the aorta sinks aneurysm paper

plosoneA paper on an experimental treatment for abdominal aneurysms has been retracted after it was discovered samples had been taken from the wrong part of the aorta.

Here is the PLOS ONE notice for “Inhibition of Rho-Kinase by Fasudil Suppresses Formation and Progression of Experimental Abdominal Aortic Aneurysms:” Continue reading Sampling the wrong part of the aorta sinks aneurysm paper

Last month, we reported on a 2012 paper in Interface whose authors had the journal issue an expression of concern about it because of “some of the data and methods.” At the time, The Royal Veterinary College at the University of London was conducting an investigation into the research.

Today, that expression of concern was upgraded to a retraction. Here’s the notice: Continue reading Elephant femur paper subject to expression of concern retracted following investigation

The tell-tale heart: Cardiovascular surgeons notch two retractions for plagiarism

Sometimes plagiarism can be tricky to catch when an article has to be translated before publication.

That seems to be the case for two papers out of a hospital in Canakkale, Turkey, that discussed results of two different kinds of heart surgery.

Here’s the retraction notice for “The effects of 21 and 23 milimeter aortic valve prosthesis on hemodynamic performance and functional capacity in young adults,” in the Pakistan Journal of Medical Sciences: Continue reading The tell-tale heart: Cardiovascular surgeons notch two retractions for plagiarism

Authors retract highly cited XMRV-prostate cancer link paper from PNAS

pnas 1113Retraction Watch readers may recall that nearly two years ago, an editor at PLOS declared the scientific story of a link between XMRV, aka xenotropic murine leukemia-related virus, and prostate cancer over, saying that a retraction from PLOS Pathogens was the “final chapter.” (That retraction led to an apology from the journal about how it was handled.)

Perhaps, however, there is an epilogue. This week, a group of authors who published a highly cited 2009 study in the Proceedings of the National Academy of Sciences (PNAS) making the same link retracted it. Here’s the notice, signed by all five authors: Continue reading Authors retract highly cited XMRV-prostate cancer link paper from PNAS

Immunology paper retracted for inappropriate presentation but “no evidence of intentional misconduct”

immun40_4.c1.inddA paper in Immnunity has been retracted after two separate panels determined some of the figures “inappropriately presented” the data but cleared the team of wrongdoing.

However, the original data are now unavailable, according to the notice, so there’s no way to know if the paper’s conclusions are sound.

Here’s the notice for “Suppressors of Cytokine Signaling 2 and 3 Diametrically Control Macrophage Polarization”: Continue reading Immunology paper retracted for inappropriate presentation but “no evidence of intentional misconduct”

Serial figure fakers have expression of concern upgraded to a retraction

Another retraction has appeared up for frequent fliers Jun Li, Kailun Zhang and Jiahong Xia at Huazhong Science and Technology University in Wuhan, China.

We’ve covered them twice before, for a variety of retractions, corrections, and expressions of concern.

The retraction, in Clinical and Experimental Immunology, upgrades an expression of concern published earlier this year, and is the team’s fourth.

Here’s the notice for “CCR5 blockade in combination with rapamycin prolongs cardiac allograft survival in mice”: Continue reading Serial figure fakers have expression of concern upgraded to a retraction

Anesthesiologist “con man” apologizes for faking cover-up charges against Australian university

It’s not uncommon for scientists accused of wrongdoing — especially if they’re fired for it — to attempt to muddy the waters by claiming that they are being framed because they had threatened to blow the whistle on others.  Some of those stories have more than a grain of truth to them.

Here’s one that doesn’t.

Paul Barach, an anesthesiologist who accused his former employer, the University of New South Wales, of a massive cover-up — and in turn accused by his employer of being an academic grifter — has admitted making up the affair.

The Australian, which broke the story, says Barach — a U.S.-born physician — has apologized for making the claims. According to an earlier article in the paper:
