NEJM pulls letter by heart researcher who faked patient records

Screen Shot 2015-11-30 at 10.08.23 AMA heart researcher who fabricated patient records has notched retraction number six — this time, for a letter in the New England Journal of Medicine. She has two more retractions forthcoming.

The retraction comes at the request of Anna Ahimastos’s co-authors, following an investigation into her work by her former workplace, the Baker IDI Heart and Diabetes Institute. The investigation was not able to verify the data referenced in the letter, which includes a citation for a recently retracted JAMA paper.

The retraction note is similar to others for Ahimastos’s papers:

Memorial University in Canada has released a five-year-old report of an investigation, confirming a former nutrition professor had committed misconduct in a 2001 paper.

The 53-page report — about Ranjit Kumar Chandra, a prominent and once-lauded researcher — focuses on a Nutrition paper that examined the effectiveness of vitamins patented by Chandra. The report, authored by MUN professor emeritus William Pryse-Phillips, lists 41 problems with the paper, which it concludes:

…was not in full compliance with the scientific, ethical, and/or integrity standards of Memorial University at the time.

The paper was retracted in 2005; the report is dated 2009. We asked Pryse-Phillips why the university took so long to release it. He told us:

Four JBC retractions add up to 8 in total for cancer research pair

47.coverThe Journal of Biological Chemistry is retracting four papers by a pair of cancer researchers at Tulane University, bringing their total to eight.

The retractions are all for reusing parts of figures, either within a paper or from other papers by the pair. Thanks to a new policy at the journal to publish informative notes, we know the figures that were problematic, and the papers that they borrow from. 

An investigation by Tong Wu and Chang Han’s former employer, the University of Pittsburgh, had already led to four retractions for the pair, including two issued this summer.

First up, “Activation of cytosolic phospholipase A2α through nitric oxide-induced S-nitrosylation. Involvement of inducible nitric-oxide synthase and cyclooxygenase-2,” which has been cited 50 times, according to Thomson Scientific’s Web of Knowledge. Here’s the note: Continue reading Four JBC retractions add up to 8 in total for cancer research pair

A Retraction Watch retraction: Our 2013 advice on reporting misconduct turns out to have been wrong

2015_06_miniNearly three years ago, our co-founders Ivan Oransky and Adam Marcus penned a column in Lab Times suggesting ways for readers to report alleged scientific misconduct. They are now retracting that advice.

In the retracted column, they suggested initially contacting the editor of the journal that published the potentially problematic work, and if the editor suggests it, contact the authors of that work. In their latest column for Lab Times, Oransky and Marcus say: Forget that advice.  Continue reading A Retraction Watch retraction: Our 2013 advice on reporting misconduct turns out to have been wrong

Investigation finds data issues polluted air quality paper

1-s2.0-S0013935113X0009X-cov150hAn investigation at the Queensland University of Technology in Australia has found that a paper on air pollution and human health contains a host of issues with the data and its analysis. The paper has been retracted with a very detailed note from Environmental Research.

The issues with the paper include an “incorrect analysis of the data,” and its failure to properly cite multiple papers and one researcher’s contributions. Ultimately, according to the retraction note, the investigation found that the “conclusions of the paper are flawed.”

“Submicrometer particles and their effects on the association between air temperature and mortality in Brisbane, Australia” has been cited three times, according to Thomson Scientific’s Web of Knowledge.

The retraction note is very, very detailed. It outlines the problems with the paper:

JAMA retracts second paper by heart researcher

Screen-Shot-2015-10-27-at-10.53.53-AMA heart researcher who fabricated trial participants has notched a second JAMA retraction. The retraction comes at the request of her co-authors, after an investigation by her former employer wasn’t able to confirm that this study was valid.

In September, we learned that Anna Ahimastos, who used to work at Baker IDI Heart and Diabetes Institute in Melbourne, Australia, had “fabricated [records] for trial participants that did not exist” in a JAMA trial for a blood pressure drug, according to principal investigator Bronwyn Kingwell.  That trial was retracted, along with a sub analysis.

An investigation by the institute found problems or sufficient doubt in several more publications. This second JAMA retraction is number 5 for Ahimastos, of 8 total expected.

The paper, “Effect of perindopril on large artery stiffness and aortic root diameter in patients with Marfan syndrome: a randomized controlled trial” Continue reading JAMA retracts second paper by heart researcher

A stem cell researcher who sued his employers, Harvard and Brigham & Women’s Hospital, is headed to Switzerland.

Piero Anversa‘s departure follows the dismissal of his suit last summer. Anversa filed the suit with colleague Annarosa Leri, claiming that an investigation into their work damaged their reputations:

they lost a multimillion-dollar offer to purchase their company, Autologous/Progenital; and both Plaintiffs have had possible employment offers at several institutions postponed.

Anversa’s lawyer, Tracey Miner, confirmed that he was moving:

Mol bio paper pulled by PLOS following investigation into figures

Screen Shot 2015-11-17 at 11.58.47 AMPLOS Biology has retracted a paper about the molecular details of β-catenin expression following an investigation by the first author’s institution in Italy.

The investigation, by the Istituto Nazionale per la Ricerca sul Cancro, found that there were multiple “figure anomalies.” According to the note:

An explanation of inadvertent error was given for some of the issues identified, while for two issues, a satisfactory explanation could not be provided.

First author Roberto Gherzi says none of his co-authors helped prepare the figures. The authors maintain that the conclusions are unaffected, but that assurance wasn’t enough for the journal. Here’s more from the lengthy retraction note, which provides some backstory on the “serious concerns” regarding the data:

Psychologist Jens Forster settles case by agreeing to 2 retractions

Jens Förster

Following questions about the veracity of multiple papers by his former employer, high-profile social psychologist Jens Förster has agreed to retract two papers as part of a deal with the German Society for Psychology (DGPs).

Last year, Förster had a paper retracted at the request of his former employer, the University of Amsterdam (UvA). In May, an investigation commissioned by UvA found that many of his experiments looked “too good to be true,” and eight papers showed strong signs of “low veracity.”

Just two of those papers are acknowledged in the settlement of a case by the DGPs against Förster, who currently works at Ruhr University Bochum. Here’s a translation of a notice from the DGPs from One Hour Translation:
