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diabetologiaA diabetes paper that received quite a bit of media attention when it was published in June 2013 was retracted and reissued to fix data errors shortly after publication.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

Diabetes researcher Cory Toth up to seven retractions

tothA University of Calgary diabetes researcher, Cory Toth, who told us earlier this year that he would cease publishing in the scientific literature, has two more retractions, making seven.

Both appear in Neurobiology of Disease. Here’s the notice for “Differential impact of diabetes and hypertension in the brain: Adverse effects in white matter:”

Editor in chief steps down after being found plagiarizing in her own journal

diab met syndImagine you were a cop, sitting in your squad car at the side of the road with a radar gun, when you clock someone speeding. You turn on your lights, pull the speedster over to the side of the road, and walk to her driver’s side window.

Just as you say “Driver’s license and registration, please,” you realize the driver is your squad captain. Oops.

That must have been something like what it was like — with plagiarism detection software sitting in for the radar gun — for the co-editor-in-chief of Diabetology & Metabolic Syndrome when he realized that Marilia de Brito Gomes, the other co-editor-in-chief, had published two papers in their journal that contained plagiarized passages.

Cory Toth, the University of Calgary diabetes researcher who told us last month he would stop publishing in science following a string of inappropriate manipulations, has retracted another paper.

Here’s the notice in Brain for “Intranasal insulin prevents cognitive decline, cerebral atrophy and white matter changes in murine type I diabetic encephalopathy:” Continue reading Diabetes researcher who says he will no longer publish now up to five retractions

More retractions for researcher who says he will no longer publish

diabetescoverWe’ve been alerted to two more retractions of articles by University of Calgary researcher Cory Toth, both in the journal Diabetes, for image doctoring.

One paper, from 2008, was titled “Receptor for Advanced Glycation End Products (RAGEs) and Experimental Diabetic Neuropathy.” It has been cited 93 times, according to Thomson Scientific’s Web of Knowledge. The notice states: Continue reading More retractions for researcher who says he will no longer publish

Novartis Diovan scandal claims two more papers

diabetes careA complicated story involving Novartis’s valsartan (Diovan) has led to the retraction of two more papers, one cascading from the other.

Last September, The Lancet retracted the Jikei Heart Study after a slew of retractions of related work prompted an investigation of valsartan research. That investigation found evidence of data manipulation and the failure of one researcher to note his Novartis affiliation. The company has apologized.

Here’s one retraction, from Diabetes Care, for “The Shiga Microalbuminuria Reduction Trial (SMART) Group. Reduction of Microalbuminuria in Patients With Type 2 Diabetes: The Shiga Microalbuminuria Reduction Trial (SMART):”

Misconduct at Oxford prompts retraction of insulin paper

cellmetabcoverCell Metabolism has retracted a 2006 article by a group of researchers at Oxford in England after an investigation concluded that the first author had committed misconduct.

The paper, “Nicotinamide nucleotide transhydrogenase: A key role in insulin secretion,” came from the lab of Frances Ashcroft, a world-renowned expert on ion channels. (We’ve written about Ashcroft’s lab before.)

According to the abstract: Continue reading Misconduct at Oxford prompts retraction of insulin paper

“Personal rivalry” leads to retraction of nut-health paper

ejpcHere’s a retraction that leaves us itching to know more:

The authors of a recent paper in the European Journal of Preventive Cardiology on nut intake and the risk of high blood pressure and diabetes have pulled their article from publication for an undisclosed conflict of interest.

Now, you wouldn’t know this unless you were willing to pony up the $32 to read the notice, which is behind a pay wall — something that drives us, well, nuts. But here it is:

Journal withdraws diabetes paper written by apparently bogus authors

BBRCTalk about a Trojan Horse.

Biochemical and Biophysical Research Communications has withdrawn a paper it published earlier this year on metabolic proteins linked to diabetes, not because the article was bogus but because the authors appear to have been. The work itself is accurate — indeed, it likely belongs to a Harvard scientist, Bruce Spiegelman, who’d presented his data on the subject several times recently and was in the process of preparing his results for publication. We’ve written about researchers trying to punk journals with faked articles, and about a researcher who apparently made up a co-author, but here’s something new!

Nature has the story. According to Nature, in July Spiegelman: Continue reading Journal withdraws diabetes paper written by apparently bogus authors
