“Super-surgeon” who created artificial tracheas facing new misconduct allegations

A one-time media favorite is being accused of serious misconduct in three cases where he inserted artificial windpipes into patients and treated them with stem cells. Two of the patients have died; one survives, but needs her airway cleaned every four hours by hospital staff to keep her alive.

A little over two years ago, thoracic surgeon Paolo Macchiarini soared to the top and then sunk to the bottom within days. First, his work implanting artificial tracheas hit the front page of the New York Times. Days later he was placed on house arrest for accusations of fraud and extortion.

We wrote about him a month later, when a paper of his was retracted for plagiarism.

Here’s Henry Fountain at the NYT writing about the new allegations: Continue reading “Super-surgeon” who created artificial tracheas facing new misconduct allegations

“Conscious fabrication” leads to retraction of diabetes study

diabetcoverDiabetologia has retracted a 2011 meeting abstract from a group in Sweden, indicating that the second author has been found guilty of research misconduct — a charge the scientist denies.

The abstract, “Reduced syntaxin-5 in skeletal muscle of patients with type 2 diabetes is linked to increased diacylglycerol, activation of PKCtheta and impaired insulin signalling,” was presented at the annual meeting of the European Association of the Study of Diabetes. The first author was Kurt Højlund, who now is at the University of Southern Denmark. The second author was Pontus Boström, of the Karolinska Institutet.

Deceased researcher has two more papers retracted

free radicalA late researcher in Italy who has already been blamed for image manipulation in a PLOS ONE retraction notice has had two more papers retracted, both from Free Radical Biology and Medicine.

Here’s the notice for 2007’s “Redox regulation of 7-ketocholesterol-induced apoptosis by β-carotene in human macrophages,” by Paola Palozza and colleagues: Continue reading Deceased researcher has two more papers retracted

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

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): Continue reading Danish committee rejects much of Klarlund Pedersen’s appeal of misconduct findings

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

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

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

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: Continue reading Researcher with 25 retractions covered up other fraud, says university

Cardiology researcher who admitted to fraud earns four-year funding ban

dfg_logoA researcher who admitted in 2012 to “intentional and systematic manipulation” of data and had two papers retracted has been banned from funding by the German Research Foundation (DFG).

Dennis Rottländer, who will also be returning prize money he was awarded for the research, worked in Uta C. Hoppe’s lab at the University of Cologne. Hoppe, now at University Hospital Salzburg, remains under investigation, according to a statement from the DFG.
