“Wide differences in the memories” prompt expression of concern for Poldermans paper

with 2 comments

EHJThe European Heart Journal has issued an expression of concern for a 2014 2001 paper by Don Poldermans, the Dutch heart researcher who stepped down from his post at Erasmus University after being accused of misconduct.

The article, “Bisoprolol reduces cardiac death and myocardial infarction in high-risk patients as long as 2 years after successful major vascular surgery,” appeared in July and reported data from the DECREASE trial. Poldermans, who left Erasmus in 2011, has acknowledged failing to receive informed consent from some patients in one phase of the DECREASE study but denied having fabricated results.

Want bogus data, million-dollar fraud allegations and a scientist on the lam? We give you Alain Malafosse.

The British Journal of Psychiatry has retracted a June 2013 paper by Malafosse and his colleagues on the genetics of bipolar disorder in children because Malafosse allegedly fabricated key data in the study.

The article, “Childhood maltreatment and methylation of the glucocorticoid receptor gene NR3C1 in bipolar disorder,” purported to find that people with bipolar disorder who had experienced more, and more severe, abuse early in life were more likely to show epigenetic changes. According to the abstract:

The Danish Committees on Scientific Dishonesty (DCSD, Danish acronym UVVU) has partially reversed a December 2013 finding of misconduct against a scientist in Denmark, but has upheld most of its ruling.

Bente Klarlund Pedersen, whose case was tied up with that of Milena Penkowa, another scientist in Denmark found guilty of misconduct, committed misconduct in four of 12 articles examined, not six, the DCSD said in a statement last week.

Here’s the English summary (the DCSD does not name scientists under investigation publicly, but Pedersen has confirmed this is about her): Read the rest of this entry »

Australian university to repay $275K grant because of “misleading and incorrect” information

Courtesy of The Australian, we have an update on a story we first covered in late 2012.

As we reported then:

A contested retraction in Stem Cells and Development has left the Queensland University of Technology (QUT) graduate student who fought for it in limbo, uncertain if he will earn his PhD. And many of those who didn’t want the paper retracted have a significant financial interest in a company whose work was promoted by the research — despite any lack of disclosure in the now-retracted paper.

QUT refused to give the student, Luke Cormack, access to an evaluation of the data in question, but also said that it welcomed an independent probe into a related $275,000 grant.

That probe is now complete, reports The Australian’s Julie Hare, and the QUT will be paying the grant back: Read the rest of this entry »

Immunology paper retracted for inappropriate presentation but “no evidence of intentional misconduct”

with 2 comments

immun40_4.c1.inddA paper in Immnunity has been retracted after two separate panels determined some of the figures “inappropriately presented” the data but cleared the team of wrongdoing.

However, the original data are now unavailable, according to the notice, so there’s no way to know if the paper’s conclusions are sound.

Here’s the notice for “Suppressors of Cytokine Signaling 2 and 3 Diametrically Control Macrophage Polarization”: Read the rest of this entry »

The Japanese endocrinology researcher Shigeaki Kato, with at least 25 retractions to his name, is alleged to have been the ringleader of a scheme to cover up other research misconduct at the University of Tokyo, his former employer, which investigated the activity.

According to the Japan Times, Kato and three other colleagues took steps to hide evidence of image manipulation in five of 51 theses between 1996 and 2011: Read the rest of this entry »
