Spanish veterinary researcher under suspicion of creating “ghost” author, fabricating data

The Spanish press has picked up on the story of a prominent veterinary scientist in that country who has been accused of research misconduct.

According to El Pais, the researcher, Jesús Ángel Lemus, whose areas of interest include the effects of toxins on birds, ran into trouble in December when colleagues complained to the Ethics Committee of the Higher Council for Scientific Research about the reproducibility of his results and other problems. That triggered an inquiry by the CSIC into Lemus’ body of work, an investigation that, evidently, could not find a body.

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

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

Gastro journal retracts duplicate review, but what really happened?

Current Opinion in Gastroenterology is a bimonthly journal “offering a unique and wide ranging perspective on the key developments in the field” that “features hand-picked review articles from our team of expert editors.”

Apparently, those hands picked what amounted to the same “unique” article twice. The journal is retracting a 2004 paper, “Enteral feeding,” by Khursheed Jeejeebhoy, an expert in nutrition at the University of Toronto (he’s now emeritus), because it duplicates a 2003 paper with the same title.

Here’s what the notice, which, lamentably, sits behind a paywall, has to say: Continue reading Gastro journal retracts duplicate review, but what really happened?

Inquiry at Maimonides triggers two retractions in Chest, and retraining for the researchers

The journal Chest has retracted two publications — a paper and an earlier meeting abstract — from a group of researchers at Maimonides Medical Center in New York City after learning that the investigators mischaracterized the nature of their study. In addition to losing the two publications, the authors were ordered to undergo a refresher in proper research methods.

Here’s the notice for the abstract, which has been cited once, according to Thomson Scientific’s Web of Knowledge: Continue reading Inquiry at Maimonides triggers two retractions in Chest, and retraining for the researchers

Dental X-rays linked to Alzheimer’s disease? Abstract saying so temporarily withdrawn

Alzheimer’s & Dementia has “temporarily withdrawn” a 2012 abstract, slated for publication next month, linking Alzheimer’s disease with exposure to dental x-rays.

The author is Caroline Rodgers, a self-described “independent writer/researcher who investigates public health issues and advocates for change.” Although we can’t find the text, we’re guessing that its premise is similar to that of her 2011 paper in Medical Hypotheses, titled “Dental X-ray exposure and Alzheimer’s disease: a hypothetical etiological association.”

Here’s the abstract from that paper: Continue reading Dental X-rays linked to Alzheimer’s disease? Abstract saying so temporarily withdrawn
