Anesthesia journal pulls study lacking patient consent

Journal of AnesthesiaAn anesthesia journal has retracted a paper after an author admitted that the study did not obtain appropriate consent from patients receiving a neuromuscular block in muscles on the face and hands. 

The first author, Yuhji Saitoh, has the same name as a co-author of Yoshitaka Fujii, the all-time record holder with 183 retractions listed on our leaderboard. Thirty-six of those retracted papers include a co-author with the name of Yuhji Saitoh, but we were unable to confirm this is the same person listed on the newly retracted paper.  

Here’s the retraction notice, issued by the Journal of Anesthesia on August 11: Continue reading Anesthesia journal pulls study lacking patient consent

A prominent researcher in Scotland has been suspended amidst a misconduct investigation at the University of Dundee.

According to The Scotsman, the allegations against Robert Ryan center around falsifying data and duplicating figures in his work about molecular bacteriology.

You’ve been dupe’d: Results so nice, they’re published twice

obesity surgeryWith retraction notices continuing to pour in, we like to occasionally take the opportunity to cover several at a time to keep up.

We’ve compiled a handful of retractions that were all issued to papers that were published twice by at least one of the same authors — known as duplication. (Sometimes, this can be the publisher’s fault, although that doesn’t appear to be the case in any of the following examples.)

So here are five recently retracted papers that were pulled because of duplication: Continue reading You’ve been dupe’d: Results so nice, they’re published twice

USDA finds “evidence of manipulation” in vaccine study

VaccineA journal is retracting a paper by scientists at the U.S. Department of Agriculture about a vaccine to protect fish from a deadly bacterial infection, after an investigation found evidence of data manipulation. 

The retraction notice — which appears in the journal Vaccine — cites an investigation by the USDA. It also notes that the authors — who are no longer with the USDA — have not agreed to the retraction.

Here’s the retraction notice, issued on August 20: Continue reading USDA finds “evidence of manipulation” in vaccine study

U Colorado’s former “golden boy” up to 7 retractions

University of Colorado DenverA former graduate student at the University of Colorado Denver has gained three retractions and two expressions of concern (EOC), following an institutional probe into his work. 

Last year, we reported on an investigation by the University of Colorado Denver into the research of Rajendra Kadam, which recommended retracting 10 papers. The report also flagged eight additional papers co-authored by Kadam whose data could not be validated, raising “concerns as to the scientific validity and integrity” of the material. A few months later, we reported on some of the notices — four retractions and an EOC — that had begun to appear for Kadam’s manuscripts.

We’ve since discovered more notices, bringing his total to seven retractions and three EOCs. 

Kadam was once a prominent member in the lab of Uday Kompella, and often referred to by colleagues as the “golden boy,” according to the institution’s report. In 2012, he won a graduate student symposium award from the American Association of Pharmaceutical Scientists.

Nutrition researcher Chandra, who lost libel suit, charged with health care fraud

A nutrition researcher with multiple retractions who unsuccessfully sued the Canadian Broadcasting Corporation (CBC) for libel has been charged with defrauding a state health insurance plan.

The Toronto Star reports that a warrant has been issued for the arrest of Ranjit Kumar Chandra for billing the Ontario Health Insurance Plan for “services that were either not provided or billed inappropriately.” The charges do not appear to be related to his research: Chandra worked once a week as an allergist for the past four years, the Star reports, and the alleged fraud was at least $5,000.

7th retraction for Ohio researcher who manipulated dozens of figures

A pharmacology researcher at Ohio State University has added his seventh retraction, four years after a finding of misconduct by the U.S. Office of Integrity (ORI).

An analysis of the work of Terry Elton determined that he had

falsified and/or fabricated Western blots in eighteen (18) figures and in six (6) published papers.

 In 2012, the ORI finding, which resulted in a three-year funding ban (that is now complete), recommended that Elton retract all six papers, one of which had already been retracted at the time of the report. 

Four years later, the last of the six papers flagged by the ORI has finally been retracted by Molecular and Cellular Endocrinology.

Here’s the retraction notice: Continue reading 7th retraction for Ohio researcher who manipulated dozens of figures

A tale of two retraction notices — for the same paper

curentHere’s a strange one: We discovered a paper about an antibiotic-resistant strain of bacteria that bore two retraction notices, and each provided a different reason for retraction. One alleged misconduct; that notice still appears now. The other — which has since disappeared — said the paper was submitted by mistake.

“In vitro effect of boric acid and calcium fructoborate esters against methicillinresistant Staphylococcus aureus strain” was published in the South-Western Journal of Horticulture, Biology and Environment. The full text isn’t available on the journal’s website.

First, here’s the text in the retraction notice that appears when one clicks on the “download full text” link in the table of contents next to the paper: Continue reading A tale of two retraction notices — for the same paper

A retraction cluster? Two papers retracted for overlap with other retractions

molecular biology reportA cluster of papers by different authors has been retracted for sharing text, even though some papers were submitted at the same time.

How is that possible? A spokesperson for Springer told us that they have reason to believe a third-party company may have helped prepare the papers for publication, and in the process might have spread the material around to multiple manuscripts.

The details of the cluster are a bit perplexing, so bear with us. Two of the papers — that were published only months apart — have already been retracted, as we reported in April. Now, two other papers have been retracted from Molecular Biology Reports — and both notices cite the previously retracted papers. The new notices also say that there’s reason to believe that the peer-review process was compromised.

All papers conclude that a certain polymorphism could signal a risk for coronary artery disease among Chinese people.

We’ll start with the retraction notice for “Fibroblast growth factor receptor 4 polymorphisms and coronary artery disease: a case control study,” which cites the two papers that were retracted previously:

Collateral damage: Paper — and editorial, and author’s response — retracted in one fell swoop

euro jA journal has retracted the results of a clinical trial comparing strategies for bladder tumors after the authors mischaracterized the way patients were assigned to each procedure.

In addition, the journal European Urology has pulled a string of correspondence between author Harry Herr at Memorial Sloan Kettering Cancer Center and an outside expert, who had questioned aspects of the study totally unrelated to the methodology, such as its generalizability.

Here’s the retraction notice for ” Randomized Trial of Narrow-band Versus White-light Cystoscopy for Restaging (Second-look) Transurethral Resection of Bladder Tumors:”  Continue reading Collateral damage: Paper — and editorial, and author’s response — retracted in one fell swoop
