Neurology expresses concern over dementia study after authors report error in analysis

neurologyNeurology has issued an expression of concern over a 2013 article by a group of scientists in The Netherlands and the United States who found a potentially devastating error in their analysis.

The article, “Structural and functional brain connectivity in presymptomatic familial frontotemporal dementia,” came from the lab of John C. van Swieten, of Erasmus University in The Netherlands. According to the abstract of the article:  Continue reading Neurology expresses concern over dementia study after authors report error in analysis

Nature Medicine retracts MS paper with ghost data by former GSK researcher

naturemed1213Nearly six months after first expressing concern about the validity of a 2010 paper on multiple sclerosis, Nature Medicine has retracted the article for containing “erroneous” data — which in this case don’t seem to have existed, making them more fabricated than wrong.

The paper, “Crucial role of interleukin-7 in T helper type 17 survival and expansion in autoimmune disease,” came from a group led by Jingwu Zhang, who at the time ran GlaxoSmithKline’s Research and Development Center in Shanghai.

In June, the journal issued an expression of concern about the article after readers discovered problems with the data, as reported by Nature Medicine’s blog.

Author dispute leads to retraction of neurology paper

cjnsCall us old-fashioned, but we think that if a group of authors set out to write an article about a viewpoint, they probably ought to share that viewpoint.

But that’s not the case with a bunch of researchers led by Tjaard Ubbo Hoogenraad, a neurologist in the Netherlands specializing in Alzheimer’s disease. The study, “A Viewpoint about the Treatment of Wilson’s Disease,” appeared in the July 2013 issue of the Canadian Journal of Neurological Sciences.  (Wilson’s disease is a rare genetic disorder in which the body loses the ability to get rid of copper, which in turn accumulates with toxic effect in tissues.)

Evidently, that viewpoint wasn’t quite shared. According to the retraction notice:  Continue reading Author dispute leads to retraction of neurology paper

Retraction prompts letter of explanation by co-author — and a legal threat against Retraction Watch

ejnmmiThe European Journal of Nuclear Medicine and Molecular Imaging has an interesting exchange of retraction-related notices in its pages.

The article, “Neuroradiological advances detect abnormal neuroanatomy underlying neuropsychological impairments: the power of PET imaging,” appeared in 2011 and was written by Benjamin Hayempour and Abass Alavi, one of the pioneers in PET imaging.

According to the retraction notice:

This article has been withdrawn at the request of the Editor-in-Chief of European Journal of Nuclear Medicine and Molecular Imaging owing to the unexplained close similarity of some passages to parts of a previous publication [Rushing SE, Langleben DD. Relative function: Nuclear brain imaging in United States courts. J Psychiatry Law 2011; 39 (winter): 567–93].

Aussie university asks for retraction, investigates former neurology researcher for fraud

uqThe University of Queensland has decided to get out in front of a serious research misconduct scandal by issuing a press release about the item even before, well, we could get a hold of the story.

The affair involves Bruce Murdoch (all of his links at UQ are defunct), an expert in movement disorders such as Parkinson’s disease. Murdoch isn’t named in the release, but he is the corresponding author of the retracted paper, which is called out in the statement.

According to UQ, Murdoch seems to have published a paper in the European Journal of Neurology on research he never conducted — and on the basis of which he received a $20,000 grant. The paper has been cited six times, according to Thomson Scientific’s Web of Knowledge.

UQ has called for a retraction of the paper, although that does not appear to have happened yet.

Here’s the release, from Peter Høj, president and vice chancellor of the institution, in its entirety: Continue reading Aussie university asks for retraction, investigates former neurology researcher for fraud

The brains in Spain fall mainly on…Iran?

braininjWe’ve come across some odd examples of plagiarism in this job, from the fellow who tried to build a CV on the back of another researcher’s work, to the education researcher who, from what we can tell, preferred lifting the work of others to writing her own papers. Here’s another odd one for the pile.

A group of Iranian scholars has lost a paper in Brain Injury because they lifted it wholesale from a previously published article. What’s harder to get one’s mind around, however, is that the two papers were looking at culturally-specific aspects of brain injury. Except that one wasn’t.

The retracted paper, “Frontal acquired brain injury, substance abuse and their common psychological symptoms in the Iranian population,” appeared in 2011. Here’s the abstract, which is still available on the journal’s website (we’ll note that although the abstract is free for all, the retraction notice was behind a pay wall — an error, according to the publisher, which they remedied when we contacted them):  Continue reading The brains in Spain fall mainly on…Iran?

“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.

As the retraction notice explains: Continue reading “Technical but fundamental errors” lead to retraction of brain tumor paper

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

Purloined dissertation on stroke ends in retraction for Iranian group

intjneursciThe International Journal of Neuroscience, an Informa Healthcare journal, has retracted a paper it published earlier this year after learning that the article was the doctoral work of another scientist — not listed among the authors — that had appeared previously in a Persian-language journal.

The retraction notice, admirably thorough, explains what happened with the paper:
