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.

The notice continues: Continue reading Five papers by prominent cardiologist Hiroaki Matsubara subject to Expression of Concern

Update on Fujii: Anesthesia journal finds overwhelming statistical evidence of data fabrication

There’s a bit more this afternoon on the story of Yoshitaka Fujii, the Japanese anesthesiologist accused of fraud and other misconduct that we reported on yesterday.

The British journal Anaesthesia, which has been looking into Fujii’s research record, has posted four articles and editorials about the case and related issues on its website. One in particular is remarkable for its conclusions. Written by a UK anesthesiologist named John Carlisle, the article claims to have analyzed 169 randomized controlled trials that Fujii conducted between 1991 and 2011.

According to the abstract (which we formatted for readability, and which should be online shortly, we’re told): Continue reading Update on Fujii: Anesthesia journal finds overwhelming statistical evidence of data fabrication

Plagiarism leads to seven retractions (and counting) in the conservation literature

Serge Valentin Pangou

An ecology researcher in the Congo has found himself at the center of a plagiarism scandal that has felled seven of his papers.

As Science reports today, Serge Valentin Pangou’s work began unraveling in August 2011 after Wageningen University ecologist Patrick Jansen thought a paper he’d been asked to review for the International Journal of Biodiversity and Conservation seemed familiar — because he’d written many of the same words in a 2007 paper in Conservation Biology. He ran the manuscript through the plagiarism detection software Turnitin, and sure enough, it was about 90% identical.

Unfortunately for Pangou, Jansen’s co-author on the Conservation Biology paper was Pierre-Michel Forget, whose father, as Science notes, “was a well-known private detective in France.” Forget and Jansen took a careful look at a number of Pangou’s papers, Continue reading Plagiarism leads to seven retractions (and counting) in the conservation literature

Journal yanks anemia paper over duplicate data

Blood Cells, Molecules, and Diseases (that’s one title) has retracted a 2011 paper, “Comparative proteomics reveals deficiency of NHE-1 (Slc9a1) in RBCs from the beta-adducin knockout mouse model of hemolytic anemia,” after learning from a reader that the data it contained were previously published by a competing publication.

As the notice explains: Continue reading Journal yanks anemia paper over duplicate data

Major fraud probe of Japanese anesthesiologist Yoshitaka Fujii may challenge retraction record

We have learned that a widely published Japanese anesthesiologist is under investigation by his university over concerns that he engaged in repeated fraud for decades that has tainted roughly 180 articles—many of which may be retracted as a result.

In a related move, the journal Clinical Therapeutics is retracting papers by the researcher, Yoshitaka Fujii, most recently of Toho University, in Tokyo. Judy Pachella, managing editor of the journal, confirmed the retractions but would not state how many papers were affected. Clinical Therapeutics published 17 articles by Fujii, between 2003 and 2010.

Neuro journal retracts case study with redundant data

If that headline has you scratching your, well, head, we don’t blame you. After all, case studies are, by definition, unique — but not this one.

Neurological Sciences, the official journal of the Italian Society of Neurology, has retracted a 2009 article by a Korean scientist after learning that the manuscript contained elements of a 2007 publication in a different publication.

According to the notice: Continue reading Neuro journal retracts case study with redundant data

Another withdrawal by MD Anderson’s Aggarwal, again for unclear reasons

Bharat B. Aggarwal, the MD Anderson researcher under investigation at his institution over concerns of image manipulation, has withdrawn a second paper, although you’d never know why from the statement.

The notice for the article, “Evidence for the critical roles of NF-κB p65 and specificity proteins in the apoptosis-inducing activity of proteasome inhibitors in leukemia cells,” is pretty minimal: Continue reading Another withdrawal by MD Anderson’s Aggarwal, again for unclear reasons

On second thought: Transplant paper retracted for researcher error

When a group from Saint Louis University published a case report in Pediatric Transplantation on a baby with an unusual infection after kidney transplant surgery, they thought they’d stumbled on a first. At the time they wrote:

[Acalculous candidal cholecystitis] caused by Candida is an uncommon entity usually seen in the critically ill. Here, we present the case of an 18-month-old renal transplant patient who developed candidal AAC during the post-operative period. Previous articles have addressed acalculous cholecystitis secondary to a variety of causes, or addressed a wide variety of Candida infections in the biliary tract, but this is the first discussion of cholecystitis caused by Candida without confounding factors such as biliary calculi or multiple pathogens. After the discussion of our patient’s case, we also reviewed the English-language literature regarding candidal AAC and discussed diagnosis, treatment, and mortality.

A year later, however, the group is walking back their article. A retraction notice in the journal states that: Continue reading On second thought: Transplant paper retracted for researcher error

Two more retractions in respiratory journal as University of Louisville completes investigation

Last July, we reported on four retractions by a group of researchers at the University of Louisville, and we noted that the scientists’ work was under investigation. That investigation has apparently concluded, according to a retraction notice in the American Journal of Respiratory Cell and Molecular Biology for two of their papers: Continue reading Two more retractions in respiratory journal as University of Louisville completes investigation

Updated: Slate retracts story on Glenn McGee and Celltex following lawsuit threats, as McGee resigns from company

Slate has retracted a story about controversial bioethicist Glenn McGee and his involvement with Celltex Therapeutics, a Texas-based company that says it extracts and banks stem cells from people’s fat. Where the story by University of Minnesota bioethicist Carl Elliott once appeared now sits this editor’s note: Continue reading Updated: Slate retracts story on Glenn McGee and Celltex following lawsuit threats, as McGee resigns from company
