“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.

Retraction, tell-all style, for breast cancer radiology paper

acta radHere at Retraction Watch, we don’t believe in the expression “TMI.” But this case features a level of detail we’re not sure we’ve seen before.

Acta Radiologica has pulled a 2012 article on breast cancer imaging for being a duplicate publication — a sin the retraction notice takes great pains to point out.

The notice, written by journal editor Arnulf Skjennald, has the blow-by-blow feel of a police report: Continue reading Retraction, tell-all style, for breast cancer radiology paper

Last month, PubPeer announced that a scientist had threatened to sue the site for defamation. At the time, all PubPeer would say was that the “prospective plaintiff” is a US researcher” who was “aggrieved at the treatment his papers are getting on our site.”

Today, PubPeer revealed the that the prospective plaintiff was Fazlul Sarkar, a distinguished professor of pathology at Wayne State University in Detroit. Sarkar’s attorney, Nicholas Roumel, tells us that Sarkar had a job offer from the University of Mississippi, which rescinded it after seeing comments about his work on PubPeer.

We asked to see the letter rescinding the offer, but Roumel said he couldn’t send it because he and Sarkar are “in the process of making a claim against them.”

We also asked if there was an investigation into Sarkar’s work. Roumel told us:

As for any investigation, federal regulations make such things strictly confidential, so I can’t comment either way.
