Retraction Watch

Tired of waiting for a university, a publisher commissions its own investigation — and retracts two papers

The journal Diabetes has retracted two 2006 papers by a group of researchers in Germany whose work has long been the subject of concerns about image duplication and manipulation.

The first author of the articles is Kathrin Maedler, a prominent diabetes specialist at the University of Bremen, where she’d been a named professor but lost the title over the affair. Maedler’s group now has four retractions resulting from problematic figures.

The University of Bremen in 2016 found insufficient evidence that Maedler committed research misconduct, but concluded that she was negligent. Maedler at the time told us:

Author ‘still shocked by the blatancy of the plagiarism and by the stupidity’ after a reviewer steals his work

A group of researchers in France has lost a 2019 paper in Cell Calcium because one of the authors took, um, a bit too much inspiration for the work from a manuscript he’d reviewed for another publication.

The article, “TRPV6 calcium channel regulation, downstream pathways, and therapeutic targeting in cancer,” was written by a team from the Laboratory of Excellence Ion Channel Science and Therapeutics at the University of Lille. The senior author of the paper was V’yacheslav Lehen’kyi.

Or, maybe it was John Stewart, of Moncton, New Brunswick, Canada.

As the retraction notice states:

Former UMass post-doc faked data, says federal watchdog

The U.S. Office of Research Integrity has found a former post-doc at the University of Massachusetts Medical School guilty of misconduct stemming from falsification of data.

The finding comes more than two years after a retraction referred to an investigation at U Mass. The ORI said Ozgur Tataroglu, who worked as a neurobiologist at the institution, doctored data in a published paper and two federal grant proposals. The 2015 paper, which appeared in Cell, was retracted in 2017. Tataroglu refused to sign the notice, which stated:

Anesthesiologist joins the 100-retraction club

Until this year, only one researcher — Yoshitaka Fujii — had eclipsed the century mark for retractions. But Fujii can no longer claim dibs on being the only scientist to lose three digits worth of papers.

Joachim Boldt, a fellow anesthesiologist fraudster, recently notched three more retractions, bringing his tally, by our count, to an even 100.

Boldt was one of Europe’s leading anesthesiologists for decades. A critical care specialist, he was internationally known for his work on the use of substances called volume expanders that are used during surgery to preserve blood pressure. That fame was replaced in the early part of the last decade by questions about his work, and findings of misconduct.

Georgia State researcher up to nine retractions disagrees with the journal

A prominent researcher at Georgia State University who had two papers retracted and eight subjected to expressions of concern for problematic images last year is now up to nine retractions.

Ming-Hui Zou is the common author on all nine retracted papers, which were published in the Journal of Biological Chemistry from 2003 and 2010. Of the eight papers originally subjected to expressions of concern, seven have been retracted, and one has been updated to a correction.

Here is a typical retraction notice, for “Nicotine-induced activation of AMP-activated protein kinase inhibits fatty acid synthase in 3T3L1 adipocytes: A role for oxidant stress,” referring to image duplication, and an offer by the authors to “publish an amended figure or to repeat the experiments,” which the journal declined:

The week at Retraction Watch featured:

Crossfit being awarded $4 million in sanctions in a case stemming from a now-retracted paper;
the WHO formally retracting opioid guidelines tainted by conflict of interest;
the retraction of 17 papers by one journal for citation manipulation.

Here’s what was happening elsewhere:

There are retractors in plastic surgery — and not just of the instrument kind

A plastic surgeon in Turkey has notched his fifth retraction for plagiarism and other issues.

That makes him a retractor — even if most plastic surgeons would have something else in mind if they used that term.

Ilteris Murat Emsen, then of the Department of Plastic, Reconstructive and Aesthetic Surgery at the Numune State Hospital in Erzurum, has lost five papers dating back to 2006. Four were pulled in 2009. The most recent retraction appeared last month in the European Journal of Plastic Surgery, for a 2007 article titled “Management of the large septal perforations with the support of porous high-density polyethylene (MEDPOR).”

According to the notice:

Two retractions prove fresh is best

To the list of best practices in experimental research, here’s another item to add: Always use fresh cheesecloth when separating biomasses.

We’ll explain.

WHO formally retracts opioid guidelines that came under fire

The World Health Organization has officially retracted its controversial guidelines on the use of opioid analgesics.

The agency’s move applies to two statements, issued in 2011 and 2012. Last June, WHO announced that it was “discontinuing” the guidelines in the wake of a critical report which said the documents were heavily tainted by commercial bias. According to a BMJ story published at the time:

Crossfit wins $4 million sanction in lawsuit stemming from now-retracted paper

A Federal court in California has ruled in favor of the popular training program CrossFit in its lawsuit against a nonprofit group — a competitor in fitness training — awarding the workout company nearly $4 million in sanctions.

Why are you reading about this case on Retraction Watch, you might ask? Well, at the heart of the suit, first filed in 2014, was a now-retracted 2013 study in the Journal of Strength and Conditioning Research — published by the NSCA — showing, erroneously, that CrossFit was linked to an increased risk for injuries. The journal initially corrected the article, but as CrossFit noted, the publication never acknowledged fabrication of data.

The senior author of that paper, Steven Devor, resigned his position at The Ohio State University after the retraction in mid-2017. As we reported at the time, the institution had demanded:
