Journal retracts nutrition paper, citing authors’ “unethical behavior”

A journal has retracted a paper for a somewhat unusual reason — and swapped the article with an entirely new paper by different authors.

The journal, Materia Socio-Medica, said it’s retracting a paper about diet in dialysis patients because of some of the authors “un-ethical behaviors” in previous issues of the journal. In its place, the journal has published a paper about tuberculosis, also a curious move.

Here’s the retraction notice for “Effect of Diet Education on Blood Pressure Changes and Interdialytic Weight in Hemodialysis Patients Admitted in Hajar Hospital in Shahrekord:”  Continue reading Journal retracts nutrition paper, citing authors’ “unethical behavior”

A researcher whose work has been subject to three retractions and two expressions of concern has settled a lawsuit he filed against his university for breach of contract and emotional distress.

Rakesh Kumar had sued George Washington University for $8 million, claiming that his employer had relieved him of department chair duties without following the correct procedure, following a finding of misconduct in his lab. He also claimed that the university had either leaked confidential information about an investigation into his work, or at least failed to keep that information from being posted in a comment here on Retraction Watch.

Last year, the university filed a motion to dismiss the case, but in March, a judge allowed some of it to go forward. On Thursday, the parties settled the case.

We asked Kumar’s attorney, Paul Thaler, to describe the terms of the settlement and say whether Kumar would remain employed at George Washington: Continue reading Scientist with three retractions settles lawsuit against George Washington University

Biotech journal pulls well-cited review that plagiarized from several sources

Applied Microbiology and BiotechnologyA biotechnology journal has retracted a 14-year-old review after an investigation concluded that the authors had plagiarized from numerous sources.  

The last author of the paper — which has been cited 289 times, according to Thomson Reuters Web of Science — told us the authors took a few lines from other reviews, and unintentionally left off the references.

In June 2011, the same author was denied a prestigious fellowship after an anonymous plagiarism allegation was filed against him. 

Here’s the retraction notice in Applied Microbiology and Biotechnology for “The nitrile-degrading enzymes: current status and future prospects:” Continue reading Biotech journal pulls well-cited review that plagiarized from several sources

PLOS ONE flags math paper over algorithm concerns

PLOS OnePLOS ONE has issued an expression of concern (EOC) for a 2014 math paper after readers raised concerns with its algorithm.

According to the first author of the paper — Hafsa Athar Jafree from the University of Karachi in Pakistan — none of the authors agreed to the EOC notice. She told us the paper contains a few typos, which may have made it unclear to some readers, but said the authors had provided all of the necessary information to “justify the presented algorithms.”

A PLOS ONE spokesperson told us the journal decided to issue an EOC after consulting the editorial board, which raised significant concerns about the study.

In 2014, the journal issued a correction to the study to fix several equations in the original article. 

Here’s the EOC, posted July 25: Continue reading PLOS ONE flags math paper over algorithm concerns

Saudi institution didn’t clear genotyping study

Journal of Pharmacy and Pharmacology

A journal is retracting a paper that sought to validate genotyping techniques after learning the authors skipped a key step.

The authors scanned blood samples from 500 people who visited “the Blood Bank of our institution,” as they note in the abstract, to validate the use of genotyping techniques in the Saudi population. But the authors didn’t obtain the proper clearance from their institution, King Faisal Specialist Hospital, to publish the work.

Here’s the retraction notice for “Genotyping of CYP2C19 polymorphisms and its clinical validation in the ethnic Arab population:”

PhD student expelled for submitting paper without co-authors’ consent

PLOS OneA PhD student has been expelled from a university in China after publishing a paper in PLOS ONE without the permission of her co-authors, and using an external company to complete some of the work. 

PLOS ONE has now retracted the paper, noting that they were tipped off to the problems by a reader who raised concerns about some of the figures. The notice states that the study’s first author, Zhenni Zhang, takes full responsibility. 

The last author of the paper — Zongfang Li from the Xi’an Jiaotong University in China — told us Zhang was his PhD student who was close to completing her PhD, but has now been expelled.

Here’s the retraction notice, issued on July 25: Continue reading PhD student expelled for submitting paper without co-authors’ consent

Journal retracts paper for using figures without permission

A plastic surgery journal has retracted a paper after a researcher claimed it contained three figures without his permission.

According to Aesthetic Surgery Journal’s retraction notice (which is paywalled, tsk tsk), the figures were reproduced from a paper published in a Chinese journal without the original authors’ knowledge or permission: Continue reading Journal retracts paper for using figures without permission

Biochem journal retracts paper for “striking level of similarity” with another

Molecular and Cellular Biochemistry CoverA biochemistry journal has pulled a paper after deciding that its layout and content overlapped significantly with a previously published paper.

The researcher who reported the similarity to Molecular and Cellular Biochemistry has sent us his correspondence with the journal. After a “thorough investigation,” the journal felt the paper was worth retracting.

Here’s the retraction notice for “TNF receptor-associated factor 6 regulates proliferation, apoptosis, and invasion of glioma cells:” Continue reading Biochem journal retracts paper for “striking level of similarity” with another

Nutrition study pulled after statistical flaws emerge

Nutrition JournalA paper that suggested that eating flaxseed could reduce inflammation in men at risk of heart disease has been retracted, after researchers pointed out the paper’s flaws.

The retraction is part of a large initiative on the part of nutrition researcher David Allison and colleagues to clean up the literature, which we’ve previously covered. Regarding this paper, he told us:

When we looked at the study…it was very clear that the statistical methods used were not correct. These are not matters of debate or opinion, these are just…verifiably incorrect.

The Nutrition Journal published the paper in January 2015, and retracted it in June 2016, one day after publishing a letter by Allison and a colleague critiquing the paper. 

Here’s the retraction notice for “Impact of weight loss diet associated with flaxseed on inflammatory markers in men with cardiovascular risk factors: a clinical study:” Continue reading Nutrition study pulled after statistical flaws emerge

Researcher faked emails for co-authors, submitted paper without consent

A material science journal has retracted a paper after discovering that the first author faked email addresses for co-authors to submit the paper without their permission.

The journal, Materials, also discovered that the 2016 paper had plagiarized material from a 2013 paper previously published in Metallurgical and Materials Transactions A.

Here’s the retraction notice for the paper: Continue reading Researcher faked emails for co-authors, submitted paper without consent
