Make it a double: Alcohol treatment study pulled for duplication

European Child & Adolescent Psychiatry has retracted a 2003 paper on the treatment of alcoholism for a vague “copyright violation.” But the reason appears to be that the article was largely identical to a 2002 report from one of the authors and other colleagues.

The offending paper, “Acamprosate and its efficacy in treating alcohol dependent adolescents,” appeared in June 2003 and has been cited 51 times, according to Google Scholar. The authors were Helmut Niederhofer and Wolfgang Staffen, of the Christian Doppler-Klinik, in Salzburg.

According to the rather uninformative notice: Continue reading Make it a double: Alcohol treatment study pulled for duplication

You’ve been dupe’d: Catching up on authors who liked their work enough to use it again

As we’ve noted before, we generally let duplication retractions make their way to the bottom of our to-do pile, since there’s often less of an interesting story behind them, duplication is hardly the worst of publishing sins, and the notices usually tell the story. (These are often referred to — imprecisely — as “self-plagiarism.”)

But that skews what’s represented here — boy, are there a lot of duplication retractions we haven’t covered! — and we might as well be more comprehensive. Plus, our eagle-eyed readers may find issues that we won’t see on a quick scan.

So with this post, we’re inaugurating a new feature here at Retraction Watch, “You’ve been dupe’d.” Every now and then, we’ll gather five of these duplication retractions at a time, and post them so they get into the mix, and into our category listing (see drop-down menu in right-hand column if you haven’t already). Here are the first five: Continue reading You’ve been dupe’d: Catching up on authors who liked their work enough to use it again

And then there were 28: Two more retractions for Diederik Stapel

Achtentwintig.

That’s 28 in Dutch, and is the number of retractions so far racked up by Diederik Stapel, according to our count.

The latest two to come to our attention are in the British Journal of Social Psychology, where Stapel has already had a retraction.

Here’s one notice: Continue reading And then there were 28: Two more retractions for Diederik Stapel

PLoS ONE retracts paper on treatment of tissue disease for lack of ethical approval, erroneous data

PLOS ONE has retracted an article it published earlier this year by a group from Australia who failed to receive adequate ethics approval for their study.

The paper, “Late Complications of Clinical Clostridium Histolyticum Collagenase Use in Dupuytren’s Disease,” came from Warren M. Rozen, Yasith Edirisinghe and John Crock (sorry, irony machine not working today). Dupuytren’s causes thickening of the fascia in the hands and often requires surgery.  In 2011 the FDA approved a treatment for the ailment that involves injections of an enzyme — Clostridium Histolyticum Collagenase, or CHC — into the affected area.

The Aussie article looked at the effects of CHC injections in 12 patients over one year, finding that two of the patients suffered Continue reading PLoS ONE retracts paper on treatment of tissue disease for lack of ethical approval, erroneous data

Pfizer retracts study of experimental cancer treatment figitumumab for incorrect analyses

ORI investigating University of Florida ob-gyn researcher accused of misconduct

A prominent researcher at the University of Florida is under federal investigation for research misconduct and has lost at least one paper as a result of the fraud.

The researcher, Nasser Chegini, was a professor of obstetrics and gynecology at the U of Florida until about six months ago, when he retired, according to the chair’s office. Nasser has received at least $4 million in federal grant funding, according to the university.

The retracted paper, “MicroRNA 21: response to hormonal therapies and regulatory function in leiomyoma, transformed leiomyoma and leiomyosarcoma cells,” was published in 2010 by Molecular Human Reproduction. The authors were Qun Pan and Xiaoping Luo and Chegini.

As the notice explains: Continue reading ORI investigating University of Florida ob-gyn researcher accused of misconduct

Jumbled analysis leads to retraction of cancer study — but also another paper

The authors of a study on cancer incidence and survival in the Dutch migrant community have retracted it after realizing they’d made some errors that significantly affected the results.

But in what seems like an appropriate reward for coming forward, the newly analyzed data, with additional information, will be part of a forthcoming paper in another journal by the same authors.

The original retrospective study came out in May 2011 in the European Journal of Cancer Prevention and found that risk and survival of breast and stomach cancers differed depending on the person’s mother country. The problem was that the study jumbled up many of the participants’ homelands during the analysis.

The authors issued the following retraction: Continue reading Jumbled analysis leads to retraction of cancer study — but also another paper

Psychological Science in the news again: CNN retracts story on hormone-voting link

It’s not often that wade into retractions in the mainstream media on this blog, but in this case, we’ll make an exception.

As Politico and Poynter — and probably others — have reported, CNN has retracted a story about a yet-to-be-published study in Psychological Science claiming to find a link between estrogen and elections (disclosure: Ivan’s wife works at CNN). Specifically, the researchers reported that the well-documented preference among single women for President Obama might be rooted in their sex hormones, while that of married women for Mitt Romney seems to reflect their own ovulatory cycle. Or something like that.

Here’s the money part of the piece, which can still be found floating around on the web: Continue reading Psychological Science in the news again: CNN retracts story on hormone-voting link

HIV paper retracted after authors recommend a colleague as a reviewer

Nothing like a little home cooking.

Genetic Vaccines and Therapy (GVT) has retracted a paper by a group of Pakistani authors who recommended one of their colleagues as a reviewer for their manuscript.

That’s not all: According to the journal, the researchers apparently also misappropriated data from a previous study.

The article in question, “Structure based sequence analysis & epitope prediction of gp41 HIV1 envelope glycoprotein isolated in Pakistan,” was published in June 2012. The first author is  Syyada Samra Jafri, who we see as being at the University of the Punjab in Lahore. According to the retraction notice: Continue reading HIV paper retracted after authors recommend a colleague as a reviewer
