Retraction for image issues forces correction of herbal remedies editorial

jmm mayBack in March, we wrote about the case of Chinese researchers who pulled their 2011 paper in the Journal of Molecular Medicine on ginseng’s potential as a heart remedy because a couple of their images were suspect (duplicated was the word they’d used).

Turns out the journal suffered some collateral damage. JMM also has corrected a “Clinical Implications” article by a group of Canadian researchers about the defunct ginseng paper.

The article, “Use of ginseng to reduce post-myocardial adverse myocardial remodeling: applying scientific principles to the use of herbal therapies,”  appeared in the same issue as the original, but for some reason the correction notice appeared online only last week.

It states: Continue reading Retraction for image issues forces correction of herbal remedies editorial

Heart pulls sodium meta-analysis over duplicated, and now missing, data

heart cover may13The journal Heart has retracted a 2012 meta-analysis after learning that two of the six studies included in the review contained duplicated data.  Those studies, it so happens, were conducted by one of the co-authors.

The article, “Low sodium versus normal sodium diets in systolic heart failure: systematic review and meta-analysis,” came from an eclectic group of authors from the United States, Canada and Italy (the first author is listed as being at a Wegmans pharmacy in Ithaca, N.Y.). The paper, published online in August 2012, purported to find that: Continue reading Heart pulls sodium meta-analysis over duplicated, and now missing, data

Pfizer database errors cause two voluminous retractions for JACC statin-biomarker papers

Jacc1212coverCoding errors in a database maintained by Pfizer have led authors to retract two heart biomarker papers in the Journal of the American College of Cardiology.

The two notices, for “Prediction of cardiovascular events in statin-treated patients by lipid and non-lipid biomarkers” and “Plasma PCSK9 levels and clinical outcomes in the TNT (Treating to New Targets) Trial,” are highly detailed and say the same thing: Continue reading Pfizer database errors cause two voluminous retractions for JACC statin-biomarker papers

Heart attack: Two cardiology retractions, plus a notice of duplication, in three different journals

circ researchWe’ve come across three notices in cardiology journals this week, so although they’re unrelated, we’re gathering them here.

Image problems lead to demise of paper on ginseng for heart attack

JMM march13coverA group of researchers from Shangdong, China, has retracted their 2011 paper in the Journal of Molecular Medicine on the heart-protective properties of a substance in ginseng because the article contained dodgy figures.

The article, “Ginsenoside-Rg1 enhances angiogenesis and ameliorates ventricular remodeling in a rat model of myocardial infarction,” purported to show that ginsenoside: Continue reading Image problems lead to demise of paper on ginseng for heart attack

Cardiologist accused of misconduct strikes back in a journal

EBPOM_00219_M3Retraction Watch readers may recall the case of Don Poldermans, a prominent Dutch cardiology researcher who left a research position in late 2011 amid an investigation into his work. In a letter in the American Journal of Medicine titled “Scientific Fraud or a Rush to Judgement?” Poldermans — three of whose papers are subject to Expressions of Concern — tries to set the record straight, something he has tried to do before.

Poldermans is responding to an editorial by Vineet Chopra and Kim Eagle, “Perioperative Mischief: The Price of Academic Misconduct,” which Chopra and Eagle based on a November 2011 press release: Continue reading Cardiologist accused of misconduct strikes back in a journal

Another win for transparency: JBC takes a step forward, adding details to some retraction notices

jbc 3115Retraction Watch readers may recall that we have been frequent critics of the Journal of Biological Chemistry (JBC) — published by the American Society for Biochemistry & Molecular Biology (ASBMB) — for their opaque retraction notices. Such notices often read simply “This article has been withdrawn by the authors.”

But we are — despite what some might say is evidence to the contrary — eternal optimists, so when the ASBMB announced they were hiring a manager of publication ethics late last year, we cheered. (Patricia Valdez, a former NIH staff scientist, has since filled that position.) And today, we have another reason to say “Hurrah!”: JBC retraction notices will now include “additional details provided by official [Office of Research Integrity] ORI or institutional reports,” the journal tells us.

Here, for example, are five retractions in the March 1, 2013, issue by former University of Kentucky scientist Eric J. Smart, whom the ORI found to have faked dozens of images: Continue reading Another win for transparency: JBC takes a step forward, adding details to some retraction notices

Double dipping on exercise/cardiac risk paper leads to retraction

intjneurosciThe International Journal of Neuroscience has retracted a September 2005 paper by a group from Turkey who published the same article in the same month in a different journal.

The research involved looking at concentrations of blood fats in athletes and less vigorous folk, “and to examine the risks of cardiovascular diseases.”It found that:

… medium and high level of exercises did not cause significant differences in lipid and lipoprotein levels, but the sex differences were very pronounced” with “lipid and lipoprotein profile of female subjects was found to be better than that of males”.

Here’s the notice: Continue reading Double dipping on exercise/cardiac risk paper leads to retraction

After three retractions, five expressions of concern, cardiologist Matsubara resigns post

matsubaraHiroaki Matsubara, a leading Japanese cardiology researcher who has had three papers retracted and another five subject to expressions of concern, has resigned from Kyoto Prefectural University, according to local media.

Mainichi Shimbun reports — according to our roughest of (Google) translations — that Kyoto Prefectural University accepted Matsubara’s resignation following an investigation. That investigation — which the university had told us about last year — revealed serious problems with 27 studies.

As we noted last March: Continue reading After three retractions, five expressions of concern, cardiologist Matsubara resigns post

Paper by fake cardiologist retracted

j patient safetyRetraction Watch readers may recall the case of William Hamman, the United Airlines pilot who claimed to be a cardiologist until the Associated Press uncovered him in late 2010. Hamman had published at least six papers, and since the revelations has had one retraction and one erratum, by our count.

Now comes another retraction, in the Journal of Patient Safety. Here’s the (paywalled) notice, signed by journal editor Charles Denham: Continue reading Paper by fake cardiologist retracted
