The journal Scientifica has retracted a 2016 paper on gut disease in turkeys for a rafter of sins including plagiarism and authors plucked out of thin air.
The article, “Role of wheat based diet on the pathology of necrotic enteritis in turkeys,” was purportedly written by a team from Pakistan and France. But it turns out the first author, one Sajid Umar, appears to have misrepresented his affiliations and added names to the list of authors that didn’t belong there. He also plagiarized, although the journal took pains to avoid saying as much.
What Caught Our Attention: Potassium-rich diets are thought to be “heart-healthy,” and after examining the average dietary habits of Ghanaian adults, researchers determined the average potassium (K) intake to be well below global standards. However, the authors’ calculations of potassium intake per capita were too low by factor of 10, resulting in the incorrect conclusion that the average potassium intake was only 856 mg per day, an amount substantially lower than the World Health Organization (WHO) recommendation of 3510 mg/day. The new calculations show an average K intake of 8,560 mg/day, well over the WHO guideline.
We asked the corresponding author, David Oscar Yawson, about the source of the error, and he responded:
When Retraction Watch began in 2010, our co-founders Ivan Oransky and Adam Marcus quickly realized they couldn’t keep up with the hundreds of retractions that appeared each year. And the problem has only gotten worse — although we’ve added staff, the number of retractions issued each year has increased dramatically. According to our growing database, more than 1300 retractions were issued last year (and that doesn’t include expressions of concern and errata). So to get new notices in front of readers more quickly, we’ve started a new feature called “Caught our Notice,” where we highlight a recent notice that stood out from the others. If you have any information about what happened, feel free to contact us at firstname.lastname@example.org.
A computer science journal has retracted two papers, after discovering “a conflict of interest between the handling editor and one of the authors.”
Matt Hodgkinson, head of research integrity at Hindawi Limited, which publishes the journal Scientific World Journal, told us that the conflict of interest stemmed from the fact that Zheng Xu, an author on both papers, and Xiangfeng Luo, the handling editor on the papers, were “frequent collaborators.”
Xu—who is based at The Third Research Institute of Ministry of Public Security in Shanghai—and Luo—a professor in the School of Computer Engineering and Science at Shanghai University—have co-authored dozens of papers together, including several that were cited in the now-retracted articles. Luo also told us that Xu was his former PhD student.
A publisher has issued an expression of concern (EoC) about a study that claimed children with same-sex parents were at greater risk of depression and abuse, after posters using statistics from the paper to support a homophobic message appeared in Australia and the US.
On Aug. 21, several newswebsites reported that these posters were appearing in Melbourne, Australia, citing claims from a 2016 paper published in Depression Research and Treatment, which said that children with same-sex parents are more at risk for depression, abuse, and obesity than children with opposite-sex parents. The poster had also appeared previously in Minneapolis and has been traced to a neo-Nazi group, as reported by HuffPost Australia. Australia is preparing for a national, non-binding, mail-in vote on whether to provide marriage equality for same-sex couples.
The EoC mechanism, which was chosen by the journal’s publisher, Hindawi, is an unusual choice here. The paper’s author, D. Paul Sullins, a sociology professor at The Catholic University of America and the paper’s author, told Retraction Watch that Hindawi contacted him Aug. 21 about the decision. Initially, he told us he didn’t have any “particular objection to it,” but later told us he changed his mind after he read more about COPE’s guidelines for EoCs: Continue reading Publisher flags paper on same-sex parenting after neo-Nazi group cites it
The researcher whose brazen theft of a manuscript he had reviewed prompted a “Dear plagiarist” letter from the aggrieved author once the deceit was discovered has lost a second paper for plagiarism.
International Scholarly Research Notices, a Hindawi publication, has retracted a 2012 study by Carmine Finelli and colleagues, citing widespread misuse of text from two previously published articles. The removal was prompted by the curiosity of a scientist in England who, on reading about Finelli’s first retraction, made the logical assumption: once a plagiarist, often a plagiarist.
Dibyendu Talukdar, listed at the University of Calcutta in West Bengal, India, is the sole author on three retracted papers. He shares five new retractions with Tulika Talukdar listed at the University of North Bengal. That brings their totals to nine and six, respectively. (We’re not sure if the Drs. Talukdar are related).
When two surgeons in Greece learned that a patient had developed a rare side effect following weight loss surgery, they were eager to publish the case.
After extensive testing, the patient was diagnosed with Wernicke’s encephalopathy—a neurological disorder caused by thiamine deficiency—following a sleeve gastrectomy procedure. As the authors note in the paper, they had seen only eight other cases following the procedure in the literature.
It turns out, theirs was not the ninth. After the patient unfortunately died, he was examined by a coroner, who ruled he did not, in fact, have Wernicke’s encephalopathy. So Dimitrios Manatakis and Nikolaos Georgopoulos, both based at Athens Naval and Veterans Hospital in Greece, have retracted their 2014 case study.
