Tell-tale hearts: Cardiology journals retract redundant articles

The European Journal of Cardiothoracic Surgery has retracted a 2007 article by Chinese researchers after the senior author decided he liked the data so nice he’d publish them twice. And he appears to have done so without the knowledge of the corresponding author.

Here’s the notice for the paper, titled “Open-heart surgery in patients with liver cirrhosis”: Continue reading Tell-tale hearts: Cardiology journals retract redundant articles

Circulation retracts four papers by author who misled on IRB approval

Circulation has retracted four articles by a pediatric cardiologist in Japan who failed to obtain ethics approval for the studies in question but evidently lied about it to the journal.

The researcher, Hideaki Senzaki, of Saitama Medical University, is a highly-published investigator who trained for a time with at Johns Hopkins.

Five papers by prominent cardiologist Hiroaki Matsubara subject to Expression of Concern

Hiroaki Matsubara

The American Heart Association, which publishes a number of journals, has issued an Expression of Concern about five papers in three of their publications, following allegations of image manipulation. All of the papers include Hiroaki Matsubara, of Kyoto Prefectural University, as a co-author.

The notice begins:

It has come to the attention of the American Heart Association (AHA), in a public manner, that there are questions concerning a number of figures in several AHA journals’ articles…

The “public manner” was three posts last year on the Abnormal Science blog, available here, here and here, alleging that images were manipulated in the manuscripts, and that histology slides were reused.

Three AHA journals retract lipid papers over “negligent” record-keeping, image issues and more

Three journals belonging to the American Heart Association are dealing with a data manipulation case involving a Japanese scientist who collaborated with some of the United States’ most prominent  cardiac specialists.

Circulation has retracted a 2008 article after the researchers said the lead author’s sloppy record-keeping prevented them from reproducing their experiments. We think there might be a bit more to the story.

University of Perugia researcher faces trial for embezzlement, fraud following 13 retractions and Expressions of Concern

Stefano Fiorucci, a gastroenterology researcher at the University of Perugia in Italy, has been indicted for fraud and embezzlement, after a university investigation found that he had manipulated images in papers that he used to win about 2 million Euros in grant funding.

The case, which has so far resulted in four retractions and nine Expressions of Concern, has dragged on for several years. The trial is scheduled for July. It’s the first time that embezzlement charges have been brought against a scientist found to have committed fraud, according to reports in Umbria 24 and the Umbria Journal.

Fiorucci’s attorney, Stefano Bagianti, told Umbria 24 that there was Continue reading University of Perugia researcher faces trial for embezzlement, fraud following 13 retractions and Expressions of Concern

Another retraction of Spirocor research

Remember Spirocor, the Israeli company that closed down a clinical trial involving its “respiratory stress” test for coronary artery disease because the data underpinning the validity of the method proved unreliable? The problem led to the retraction of two articles, about which we’ve previously reported. But we also found a study by some of the same researchers, who include scientists in Israel and the United States, that had been presented at the 2010 meeting of the American Heart Association and published in the journal Circulation.

That abstract, No. 14426 “Accuracy and Usefulness of Finger Pulse Wave Analysis during Brief Deep Breathing Exercise (Respiratory Stress Response) as a Marker of Significant Coronary Artery Disease,” has now been retracted — making, to our knowledge, the entire body of published research on the Spirocor product an editorial memory.

Here’s the notice, which appears within the text of the abstract: Continue reading Another retraction of Spirocor research
