Authors retract Digestion paper for “unacceptably high number of errors”

A group of South Korean researchers has decided to withdraw a paper they recently published in the journal Digestion because it was filled with mistakes.

The paper, “Endoscopy-Based Decision Is Sufficient for Predicting Completeness in Lateral Resection Margin in Colon Endoscopic Submucosal Dissection,” was published earlier this year (and online in late 2011) by a group in Seoul. But according to the retraction notice:

Shane Mayack, a former post-doc in Harvard lab of Amy Wagers, a rising star in the stem cell field, has been sanctioned by the Office of Research Integrity for misconduct.

Mayack, who has defended her actions on this blog as honest error — albeit sloppiness — and has not admitted to wrongdoing, must undergo supervision if she receives any federal grant funding over the next three years, under the voluntary agreement.

Here’s the notice, which appeared in the Federal Register this week (and which the Boston Globe was first to report): Continue reading ORI finds Harvard stem cell lab post-doc Mayack manipulated images

A Wnt-er’s tale: Blood pulls second signaling paper from Spanish scientists over image fakery

Blood has pulled a paper 2007 paper from a group of Spanish researchers, one of whom appears to have been manipulating images.

The group’s work became the focus of expressions of concern from the Journal of Clinical Oncology this spring and in 2010.

The article, “Epigenetic regulation of Wnt-signaling pathway in acute lymphoblastic leukemia,” purported to show “a role of abnormal Wnt signaling in ALL and establish a group of patients with a significantly worse prognosis (methylated group)” and earned a commentary on the significance of the findings.

But as the notice explains, the first author lifted and manipulated a figure from a previously published article: Continue reading A Wnt-er’s tale: Blood pulls second signaling paper from Spanish scientists over image fakery

Hypertension retracts paper over data glitch

The anticipation of having one’s blood pressure measured can cause it to spike.

So, evidently, can errors in data processing — on a national scale.

Hypertension, a journal published by the American Heart Association, has retracted a 2011 paper looking at the implications of blood pressure management guidelines after the authors discovered they had bungled the merging of their data files.

As the notice explains: Continue reading Hypertension retracts paper over data glitch

It has been a while since we heard about Joachim Boldt, the German anesthesiologist whose 90-odd retractions briefly put him at the top of the heap until Yoshitaka Fujii kicked him off earlier this year.

Now, Boldt’s former institution, the Klinikum Ludwigshafen, has released a report on its investigation into the disgraced critical care expert, and the results aren’t pretty. Here’s a press release about the report, in its entirety: Continue reading Boldt inquiry concludes: False findings in at least 10 studies, but no harm to patients

Mizzou investigating faculty as one heart beats as two in plagiarized — and now retracted — cardiac paper

The American Journal of the Medical Sciences has retracted a 2012 article on premature heartbeats by a group of authors in Missouri who took “significant” liberties with an earlier paper in Heart.

The offending paper, “Ventricular ectopic beats: an overview of management considerations, “was written by Amar Jadhav and colleagues at the University of Missouri School of Medicine, in Columbia, and published in the February issue of the AJMS.

According to the retraction notice: Continue reading Mizzou investigating faculty as one heart beats as two in plagiarized — and now retracted — cardiac paper

Pharmacology journal expresses concern over “similar, but updated” review

The British Journal of Clinical Pharmacology has issued an “expression of concern” for a 2003 review article, based on a previous lecture, with close echoes to a paper that had appeared in one of The Lancet titles.

Here’s the notice for the article, by Peter Winstanley, dean of the Warwick Medical School in the United Kingdom: Continue reading Pharmacology journal expresses concern over “similar, but updated” review

Plagiarism costs Canadian lab-on-a-chip researcher a paper — in his own journal

We have long (well, for the past two years) wondered about the pitfalls of publishing in one’s own journal, and here’s a case that illustrates precisely how fraught that practice can be.

The journal Microfluidics and Nanofluidics has retracted a 2010 article, titled “Induced-charge electrokinetic phenomena,” by Dongqing Li and Yasaman Daghighi, of the University of Waterloo in Canada, for what appears to be extensive misappropriation of text and data.
