“Technical but fundamental errors” lead to retraction of brain tumor paper

neuro-oncologyThe journal Neuro-Oncology has retracted a 2011 paper by a group of researchers in Japan who had purported to find a genetic mechanism for how fluorescence can be used to diagnose certain brain tumors.

The paper, “Enhanced expression of coproporphyrinogen oxidase in malignant brain tumors: CPOX expression and 5-ALA–induced fluorescence,” reported measurements using quantitative real-time (qRT)-PCR.

Liver study a twin, gets retracted

B_SPR570_HIJO Journal.inddThe liver is the only internal organ that can regenerate. So perhaps it shouldn’t be surprising that Egyptian researchers tried to publish the same paper about liver ischemia twice  in different journals. They succeeded — for a little while, at least.

The Journal of Molecular Histology is retracting the second of the articles to appear. Titled “Effect of preischemic treatment with fenofibrate, a peroxisome proliferator-activated receptor-α ligand, on hepatic ischemia–reperfusion injury in rats,” (which is still available online) it was published in 2011 by Vivian Boshra and Amal M. Moustafa of Mansoura University.

Trouble was, in 2011 Moustafa and Boshra, in that order, had also published “Effect of fenofibrate on the experimentally induced hepatic ischemia/reperfusion injury in rats: biochemical, light, and electron microscopic studies” in the Egyptian Journal of Histology (link to pdf).

That, as we know, is not done.

Half of researchers have reported trouble reproducing published findings: MD Anderson survey

plosoneReaders of this blog — and anyone who has been following the Anil Potti saga — know that MD Anderson Cancer Center was the source of initial concerns about the reproducibility of the studies Potti, and his supervisor, Joseph Nevins, were publishing in high profile journals. So the Houston institution has a rep for dealing in issues of data quality. (We can say that with a straight face even though one MD Anderson researcher, Bharat Aggarwal, has threatened to sue us for reporting on an institutional investigation into his work, and several corrections, withdrawals, and Expressions of Concern.)

We think, therefore, that it’s worth paying attention to a new study in PLOS ONE, “A Survey on Data Reproducibility in Cancer Research Provides Insights into Our Limited Ability to Translate Findings from the Laboratory to the Clinic,” by a group of MD Anderson researchers. They found that about half of scientists at the prominent cancer hospital report being unable to reproduce data in at least one previously published study. The number approaches 60% for faculty members: Continue reading Half of researchers have reported trouble reproducing published findings: MD Anderson survey

Lack of conflict of interest disclosure undoes scoliosis study

scoliosisThe journal Scoliosis has retracted a 2012 paper by a pair of German spine doctors over what the editors have called a less-than-fully declared conflict of interest involving one of the authors.

That should be relatively straigtforward – but it’s not quite. Turns out the article does include a disclosure, although perhaps the information it contains was incomplete.

The article, “Soft braces in the treatment of Adolescent Idiopathic Scoliosis (AIS) – Review of the literature and description of a new approach,” was written by Hans-Rudolf Weiss and Mario Werkmenn. Weiss, it seems, has something of a pedigree in the field. According to this website, he practices the “Schroth method” of recurvature, a technique pioneered by his grandmother, Katharina Schroth. From the site: Continue reading Lack of conflict of interest disclosure undoes scoliosis study

Editor inadvertently spurns reviewers; retraction ensues

jvmacoverThe Journal of Multivariate Analysis has retracted a paper it was never meant to publish — a problem, it seems, of multivariate analyses.

The article, titled “Regression estimation with locally stationary long-memory errors,” came from a pair of statisticians in Chile, Wildredo Palma and Guillermo Ferreira.

It appears that the article did not pass muster with the reviewers, but that the editor somehow missed the message. As the retraction notice explains: Continue reading Editor inadvertently spurns reviewers; retraction ensues

Journal expresses concern over flawed multiple sclerosis treatment guideline

neurology may13coverThe journal Neurology has issued an Expression of Concern over recommendations it published earlier this year regarding the treatment of multiple sclerosis.

The journal’s website received multiple comments from clinicians expressing their own concern about the flawed recommendation, which was published as part of a paper titled “The American Academy of Neurology’s Top Five Choosing Wisely recommendations.” The problematic item was number 4: Continue reading Journal expresses concern over flawed multiple sclerosis treatment guideline

Referencing failure (we mean, plagiarism) leads to retraction of water testing paper

evirmonassFrom the Not Saying What You Mean Files: Environmental Monitoring and Assessment has retracted a recent article by authors in Kuwait who appear to have plagiarized, although you couldn’t really tell from the notice.

The paper, “Detection of bacterial endotoxin in drinking tap and bottled water in Kuwait,” appeared in the December 2012 issue of the journal, which is a Springer title. Continue reading Referencing failure (we mean, plagiarism) leads to retraction of water testing paper

Madoff retracts scientific paper

dcrectNo, not that Madoff.

We’re talking about Robert Madoff, editor of Diseases of the Colon & Rectum. His journal is pulling a 2012 paper by a group of authors in Spain who seem to have been unable to back up their findings when they were found to contain errors.

The article, “Perianal versus endoanal application of glyceryl trinitrate 0.4% ointment in the treatment of chronic anal fissure: results of a randomized controlled trial. Is this the solution to the headaches?” looked at what evidently is a significant side effect of nitroglycerin treatment for anal fissures: headaches. According to the abstract:

Double-dipping leads to removal of petroleum research paper

pst journalcoverIranian scientists have lost one of two articles they submitted — and published — simultaneously to different journals. Watch as confusion ensues.

The retracted paper, “Permeability Estimation of a Reservoir Based on Neural Networks Coupled with Genetic Algorithms,” appeared online in August 2011  in Petroleum Science and Technology, a Taylor & Francis journal. According to the liner notes, the paper had been received on January 15, 2010 and accepted a few weeks later. It has been cited once since, according to Thomson Scientific’s Web of Knowledge, by its authors, in a paper published in the same journal.

Meanwhile, in August 2011 the authors (minus one name) also published “Evolving neural network using real coded genetic algorithm for permeability estimation of the reservoir,”  in Expert Systems With Applications, an Elsevier title.

The standing paper — which has been cited seven times — now carries the following erratum notice (dated far into the future, September 2013): Continue reading Double-dipping leads to removal of petroleum research paper

Plagiarism: It’s just an “approach” to writing papers, right?

chemistry coverWe’ve heard a lot of rationalizations for plagiarism on this beat — “I didn’t know I had to cite that text”; “That author said it better than I ever could”; etc. — but here’s a new one for the wall of shame.

Chemistry – A European Journal is retracting a 2012 article, “A New Indicator for Potassium Ions at Physiological pH by Using a Macrocyclic Luminescent Metal Complex,”  by a group of Chinese authors who used the cut-and-paste method to put together their manuscript. That’s not unusual. But the notice is:
