Critics of Poldermans’ work baffled by NEJM stance on DECREASE papers

A pair of researchers who have been calling for the retraction of two papers by cardiology researcher Don Poldermans say the New England Journal of Medicine is  “not justified” “disappointing” in its refusal to pull the articles.

A little background: Poldermans resigned from Erasmus University in 2011 after having been accused of misconduct. Last week, we reported that the European Heart Journal had issued an expression of concern for a 2001 article on which he was first author.

The New England Journal of Medicine added editor’s notes to two of Poldermans’ articles. But as Larry Husten at Forbes reports, the journal has no intention of retracting the papers: Continue reading Critics of Poldermans’ work baffled by NEJM stance on DECREASE papers

Publisher issues statement of concern about HIV denial paper, launches investigation

frontiers phThe publisher Frontiers has issued a Statement of Concern about a paper denying that HIV causes AIDS, and has launched an investigation into how the paper was published in the first place.

The paper, “Questioning the HIV-AIDS hypothesis: 30 years of dissent,” is written by Patricia Goodson of Texas A&M University and was published on September 23 in Frontiers in Public Health. As Tara Smith, who blogged about the paper yesterday, notes: Continue reading Publisher issues statement of concern about HIV denial paper, launches investigation

Notice fails to get to the heart of cardiology retraction

cmjThis one is a little odd.

A cardiology paper from China has been retracted because “permission to report these discussions was not sought nor obtained,” though it’s unclear what “the discussions” refers to. The person to whom the discussions are attributed to in the retraction, Ji Bingyang, is not an author on the paper, and none of his papers are cited in the retracted article.

Here’s the notice in the Chinese Medical Journal for “A novel rat model of cardiopulmonary bypass for deep hypothermic circulatory arrest without blood priming”:

Data questions prompt retraction of PLOS ONE cardiovascular paper

plosonePLoS One has retracted a 2013 article on atherosclerosis in mice over concerns about the integrity of the data.

The paper, “The Effect of Soluble RAGE on Inhibition of Angiotensin II-Mediated Atherosclerosis in Apolipoprotein E Deficient Mice,” came from a group of researchers in South Korea.

It purported to show that: Continue reading Data questions prompt retraction of PLOS ONE cardiovascular paper

“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.

According to the notice: Continue reading “Wide differences in the memories” prompt expression of concern for Poldermans paper

Image manipulation forces retraction of hepatitis C paper

ljii20.v032.i04.coverA group of researchers from Egypt has lost their 2013 article on hepatitis C in the Journal of Immunoassay and Immunochemistry for fudging their figures.

The article was titled “In vitro neutralization of HCV by goat antibodies against peptides encompassing regions downstream of HVR-1 of E2 glycoprotein.” According to the abstract: Continue reading Image manipulation forces retraction of hepatitis C paper

Former UT-Southwestern cancer researchers faked data in 10 papers: ORI

ut southwesternThe Office of Research Integrity (ORI) has ruled in a case we’ve been following for nearly two years — and which seems to have been launched after Retraction Watch readers took a careful look at figures from what appeared to be an unrelated case.

Takao Takahashi and Makato Suzuki, both former postdocs at a cancer research center at UT-Southwestern, both “knowingly, intentionally, and recklessly falsified data” in a total of 10 papers, according to the ORI. Takahashi, now at Gifu University in Japan, was responsible for fakery in four papers, while Suzuki, now at Kumamoto University Hospital, also in Japan, falsified data in six.

We reported on the retraction of the four Takahashi papers, and one of the Suzuki papers, in November 2012. At that time, Adi Gazdar, the head of the lab where the researchers worked, told us that

Publisher updates with more info on staph retraction

cidWe brought you this story last week, about a paper on drug resistant staph being retracted for a lab error. Now, we’ve got an update from Rachel Safer, senior editor for medical journals at Oxford University Press, where the paper was published.

Apparently, the researchers “inadvertently relied upon the use of a test system that was not approved for the microorganism studied in their paper,” leading to the retraction, and the corresponding author of the study wasn’t initially all that responsive:
