Blood retracts two, including a disputed paper from the Karolinska Institute

The journal Blood has two retractions this month, one of which seems particularly interesting. So let’s deal with the other one first.

The paper, “MicroRNAs 15a/16-1 function as tumor suppressor genes in multiple myeloma,” appeared online in October 2010. But according to the retraction notice, the authors

have recently discovered that the cell lines used in their paper were inadvertently misidentified. The cell lines utilized in the paper have now been found to contain the bcr/abl translocation and most likely represent the K562 CML cell line, instead of MMS1 and RPM1 myeloma cell lines. Due to this issue, the relevance of the findings to myeloma and thus, the conclusions of the paper, are not supported by the data. The authors apologize to the readers, reviewers, and editors of Blood for publishing these erroneous data.

That seems straightforward enough, and we couldn’t find any evidence that this problem affected other publications.

The second paper, however, could be more significant. Continue reading Blood retracts two, including a disputed paper from the Karolinska Institute

Traffic violations: Plagiarism leads to retraction of transit modeling paper

Journal editors like to believe they are more than mere traffic cops. But here’s a case that makes us wonder.

Transportation Research Part E: Logistics and Transportation Review — yes, there are parts A-D of this — is retracting a 2009 paper which stole liberally from a 1996 article in a different journal from the same publisher, in this case Elsevier.

According to the notice, which appeared online earlier this year and in the July 2011 issue: Continue reading Traffic violations: Plagiarism leads to retraction of transit modeling paper

The Importance of Being Reproducible: Keith Baggerly tells the Anil Potti story

For those Retraction Watch readers who have been following the case of Anil Potti — who has now retracted four papers — Keith Baggerly’s name will likely be familiar. Baggerly is the bioinformatician at M.D. Anderson in Houston who has been publicly questioning, in letters, papers, and The Cancer Letter, work by Potti et. al.

Yesterday, Baggerly gave a keynote at the Council of Science Editors meeting in Baltimore. It was a fascinating — and riveting — walk through how, after a group at M.D. Anderson asked him and his team to evaluate the Potti group’s tools for predicting whether given patients would respond to different chemotherapies, Baggerly’s group unraveled the Potti research.

In his talk, Baggerly demonstrated all of the mislabeling and other easily recognized errors his team found when they sifted through the raw data. And yet there were a number of wince-inducing moments in which Baggerly described the cool reception he had from several journals.

There have been a lot of calls recently that journals should require that authors deposit their data.  There’s none more powerful than when they come at the end of a talk showing how that could have stopped a faulty clinical trial from ever starting.

Baggerly told Retraction Watch he just wants this story to get the widest attention possible, so he was glad to allow us to post his slides. They get appropriately technical, given the crowd, but it’s worth it. You can follow a very unofficial and rough transcript at this Twitter search, since Ivan live-tweeted the talk.

Retractile dysfunction? Author says journal yanked paper linking Viagra, Cialis to vision problem after legal threats

The British Journal of Ophthalmology has retracted a 2006 paper which purported to show a link between drugs for erectile dysfunction and a rare form of sudden vision loss called non-arteritic anterior ischaemic optic neuropathy, more commonly known as “Viagra blindness.”

That wouldn’t be terribly interesting, except for this: One of the authors of the paper, a researcher at the University of Alabama named Gerald McGwin Jr., told us that the journal retracted the article because it had become a tool in a lawsuit involving Pfizer, which makes Viagra, and, presumably, men who’d developed blindness after taking the drug:

The article just became too much of a pain in the rear end. It became one of those things where we couldn’t provide all the relevant documentation [to the university, which had to provide records for attorneys]

Ultimately, however, McGwin said that the BJO pulled the plug on the paper.

It was really the journal’s decision to take it out of the literature.

The retraction notice is mute on the reason for the retraction of the blindness paper (and, so far, our requests for comment seem to have fallen on deaf ears). Here’s all it says: Continue reading Retractile dysfunction? Author says journal yanked paper linking Viagra, Cialis to vision problem after legal threats

Roundup: A new record? And paper retracts story about Canadian Paxil researcher-turned pol Kutcher

We’ve both been at conferences — Adam at the Society of Cardiovascular Anesthesiologists in Savannah, and Ivan at the Council of Science Editors in Baltimore, where he’ll be on a panel today about finding fraud — so we haven’t had a lot of time to run down retractions. But there were a few retraction-related developments in the past few days that we wanted to highlight for Retraction Watch readers:

First, another great investigation by The Cancer Letter and The New York Times, this one into the International Early Lung Cancer Action Program (I-ELCAP) run by Claudia Henschke and David Yankelevitz. The design and conclusions of that trial has been criticized by other pulmonologists.

The new investigation, however, reveals that an October 2008 review of the study found that the researchers couldn’t find 90 percent of the subjects’ consent forms. That, The Cancer Letter notes, could mean a huge number of retractions that could displace Joachim Boldt as the current record holder: Continue reading Roundup: A new record? And paper retracts story about Canadian Paxil researcher-turned pol Kutcher

Feminism & Psychology study of UK birthing classes draws ire, winds up retracted

The debate — in entrenched medical circles, anyway — over whether it’s safe to give birth at home can be fierce. Just last month, for example, Nature reported that a review of the subject in the American Journal of Obstetrics & Gynecology that found home births more dangerous than those in the hospital generated so much controversy that it forced an investigation. Outside reviewers found problems, but the journal didn’t think they rose to the level of a retraction. Critics disagreed.

The same fraught subject came up in a paper published in Feminism & Psychology last year by Mary Horton-Salway and Abigail Locke. The original paper had concluded:

Our analysis suggests that the normativity of medical interventions in labour and childbirth is discursively reproduced in ante-natal classes whilst parental choice is limited by a powerful ‘rhetoric of risk’.

In other words, NCT classes were scaring women into choosing hospital births. But it turns out that conclusion wasn’t actually supported by the findings, which were based on a review of National Childbirth Trust’s classes. That led to a retraction: Continue reading Feminism & Psychology study of UK birthing classes draws ire, winds up retracted

Data fraud at Emory leads to retractions of three cardiology papers

An investigation by Emory University in Atlanta has led to the retractions of three articles containing falsified data, but the ambiguous wording of the notices leaves us wondering if they are implying more than they state.

Two of the papers appeared in the journal Arteriosclerosis, Thrombosis, and Vascular Biology. The notices in ATVB implicate a researcher named Lian Zuo, who worked in Emory’s division of cardiology.

Here’s one: Continue reading Data fraud at Emory leads to retractions of three cardiology papers

Science publishes replication of Marc Hauser study, says results hold up

There has been some news over the past few weeks about Marc Hauser, the Harvard psychologist found guilty of misconduct by the university last year. First, because Harvard had listed him in a course catalog, The Crimson said that he might be teaching again, following a ban. But that turned out not to be the case, as The Boston Globe reported.

Today, Science lifted the embargo on a paper by Hauser and Justin Wood, now of the University of Southern California, showing that results published in the journal in 2007 — and later questioned — have held up. The abstract: Continue reading Science publishes replication of Marc Hauser study, says results hold up

Duplicate publication and apparent guest authorship force retractions of two math papers

Two math journals have recently retracted two papers that share most of their text — and their first author.

The two papers were “Unsteady flows of an Oldroyd-B fluid in a cylindrical domain for a given shear stress,” in Applied Mathematics and Computation, and “A note on longitudinal flows of an Oldroyd-B fluid due to a prescribed shear stress,” in Mathematical and Computer Modelling. The studies were published online last year, but hadn’t made it into a print issue yet.

Both retraction notices, which appeared within the space of a few weeks in late February and early March, say the same thing — that is to say, nothing at all, really:

This article has been withdrawn at the request of the author(s) and/or editor. The Publisher apologizes for any inconvenience this may cause. The full Elsevier Policy on Article Withdrawal can be found at http://www.elsevier.com/locate/withdrawalpolicy.

So what was wrong with the original reports? Continue reading Duplicate publication and apparent guest authorship force retractions of two math papers

Physics Letters A paper gets retracted twice, but the issues remain “unsettled”

A retraction with a complex and yet unclear narrative appears in the April 25, 2011 issue of Physics Letters A. According to the notice, for “Nuclear spin magnetic resonance force microscopy using slice modulation:”

This article has been retracted at the request of the Editors of Physics Letters A because there are unsettled issues on how the research was carried out, how the data were acquired and analyzed. The article was removed from the journal issue before printing although it appeared online. In addition, the article was accidentally published online twice in the same journal.

As the notice suggests, this was actually the second retraction, of the same paper. Here was the first, in 2008, shortly after the paper was published. And here is a removal notice, from later that year. We haven’t come across such an occurrence before, although we’ve been writing Retraction Watch for less than a year.

There are six editors of Physics Letters A, and we tried them all for comment on the “unsettled issues.” A few pointed to Burkhard Fricke, the communicating editor for the paper, who is no longer with the journal. He didn’t respond to requests for more information.

A few referred us to Karine van Wetering, a publisher at Elsevier: Continue reading Physics Letters A paper gets retracted twice, but the issues remain “unsettled”
