Retraction 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: Read the rest of this entry »
The Journal of the American College of Cardiology, or JACC, has issued expressions of concern for three papers by Don Poldermans, the Dutch cardiologist who was fired earlier this year amid allegations of misconduct.
Cardiobrief’s Larry Husten had the story first.
The, um, heart of the matter is that neither the investigators at Erasmus Medical Center, Poldermans’ former institution, nor the JACC editors, can say whether the researchers conduct rose to the level of fabricating data. As the Notice of Concern states: Read the rest of this entry »
Dutch investigators have released their final report into the case of Diederik Stapel, the social scientist and erstwhile faculty member at Tilburg University who fabricated data in 55 articles and book chapters. So far, 31 of Stapel’s published papers have been retracted — three others have expressions of concern — although more might follow.
In addition, 10 dissertations by students Stapel supervised were found to contain fraudulent data, although those students were cleared of any wrongdoing in the inquiry.
The report — and we’re going by rough translations here — found that Stapel’s colleagues and administrators seemed to accept his results at face value. Meanwhile, his high profile at Tilburg insulated him against initial rumblings about problems with his data. As the Dutch paper NRC Handelsblad reported: Read the rest of this entry »
As Larry Husten of CardioBrief reports, Erasmus MC’s investigation included that Poldermans — perhaps best known for his work on beta-blockers — has admitted to acts of misconduct but not to fraud.
That’s not merely a distinction without a difference. Read the rest of this entry »
Poldermans update: Magazine cites lack of informed consent, bogus patient surveys, invented data and more
Larry Husten at CardioBrief has an update on the case of Don Poldermans, a leading Dutch cardiologist who was accused of various iterations of research misconduct. Poldermans was fired last November by Erasmus Medical Center, where he had been head of perioperative cardiac care before the scandal.
According to Husten, Jeroen Bax, another prominent Dutch cardiologist with strong ties to Poldermans, has been cleared of wrongdoing by his institution, Leiden University Medical Centre: Read the rest of this entry »
Erasmus University in Rotterdam has sacked a professor in cardio-vascular medicine for damaging the institution’s academic integrity and for ‘scientific misconduct’, the NRC reports on Thursday.
The professor is accused of faking academic data and compromising patient trust, the paper says. In particular, he failed to obtain patient consent for carrying out research and recorded results ‘which cannot be resolved to patient information,’ the university said.
Don Poldermans has spent years researching the risk of complications during cardio-vascular surgery and has some 500 publications to his name.
A spokesman for Poldermans told the paper he admitted not keeping to research protocols but denied faking data. Read the rest of this entry »
