‘Beggers’ can’t be choosers as another meta-analysis is retracted

A group of researchers in China may be asking for a refund after, they claim, they got bad advice from a course in writing meta-analyses that led to a retraction for plagiarism and other problems. 

They may not be alone. We’re aware of at least nine articles with similar issues that have been retracted so far, part of a batch of eye-catching meta-analyses. 

Suspicions about the now-retracted 2014 paper — and dozens of others — emerged in October of that year, when Guillaume Filion, now at the Centre for Genomic Regulation in Barcelona, wrote a blog post about the articles. Filion and a colleague, Lucas Carey, of Peking University, had noticed a flurry of meta-analyses by researchers in China that had appeared in CISCOM, the articles repository for the Research Council for Complementary Medicine. As Filion wrote:

Journal expresses a great deal of concern over deceased author’s work

A gastroenterology journal has issued an extensive expression of concern about a 2013 paper by Yoshihiro Sato, a Japanese endocrinologist who has posthumously been climbing the Retraction Watch leaderboard. (He’s now ranked number three, ahead of Diederik Stapel.)

To call the statement an “expression of concern” is like calling Charles M. Schulz a talented cartoonist, or Escoffier a pretty good cook. Indeed, the journal expresses so much concern, about, well, so much, that we’re not sure what in the paper would be left unscathed. 

Sato, formerly of Hirosaki University, currently has 77 retractions for a range of misconduct-related issues including likely data fabrication and duplication.

No delight for Turkish surgeon in authorship dispute over case study

A surgeon in Turkey has won a court case in which he argued that he deserved to be named in  a list of authors from his institution who’d published a paper. But even that doesn’t appear to have satisfied the aggrieved medic, as you’ll see. 

The article, “Late onset traumatic diaphragmatic herniation leading to intestinal obstruction and pancreatitis: two separate cases,” was written by a group from the Department of General Surgery at Ankara Numune Training and Research Hospital. The list of authors comprised Tolga Dinc, Selami Ilgaz Kayilioglu and Faruk Coskun … but not Baris Yildiz, a colleague in the department. 

The paper appeared in Case Reports in Emergency Medicine, a Hindawi title, which has issued a rather byzantine expression of concern about the article:

Chemistry researcher who studies oil wells is up to seven retractions

via Wikipedia

A chemistry researcher in India is up to seven retractions and one correction for problematic images and other issues. 

The researcher, Mahendra Yadav, was the first author on an article titled “Corrosion inhibition of tubing steel during acidization of oil and gas wells,” which appeared in 2013 in the Journal of Petroleum Engineering (JPE). Yadav, who also has a correction for similar concerns, and who has a fairly extensive entry in PubPeer, is listed as being affiliated with the Department of Applied Chemistry at the Indian School of Mines, in Dhanbad. 

According to the notice:

Caught stealing a manuscript, author blames a dead colleague

William Faulkner

As William Faulkner wrote in Requiem for a Nun, “The past is never dead. It’s not even past.” Farzad Kiani learned that lesson the hard way.

Kiani, of Istanbul Sabahattin Zaim University, was the “author” of a 2018 review article in Wireless Communications and Mobile Computing titled “A survey on management frameworks and open challenges in IoT.” According to the abstract: Continue reading Caught stealing a manuscript, author blames a dead colleague

Publisher retracts two papers, will correct five more for lab with high “level of disorganization”

A lab at the University of Malaya has lost two papers and will have to correct five more — just from one publisher — over poor lab practices.

One of the retracted papers paper tested the effects of a plant on liver damage; its notice says the paper contains overlap with another paper from the same lab that tested a different plant for the same effect — but to save time and cut costs, the authors tested both plants in animals at the same time, and collected their tissues using one kit and protocol.

The publisher (Hindawi) decided to take a second look at the work coming out of the lab of Mahmood Ameen Abdulla after people raised questions about some of his previous work, including a Scientific Reports paper that was corrected for mistaken duplications, according to Matt Hodgkinson, the head of research integrity at Hindawi. After Hindawi spotted problems, it contacted the institution, which investigated.

According to Hodgkinson, the UM investigation concluded the problems were due to errors, not deliberate misconduct. Hindawi plans to correct five more papers from Abdulla’s lab, after consulting with Hindawi’s board members following UM’s investigation:

Gluten-free turkeys? Paper on dangers of wheat-based diet in birds retracted

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.

Here’s the notice: Continue reading Gluten-free turkeys? Paper on dangers of wheat-based diet in birds retracted

Ethics, authorship concerns sink homeopathy paper by researchers arrested last year

For a host of reasons, a journal has retracted a paper co-authored by a researcher who reportedly once faced charges of practicing medicine without proper qualifications.

According to the retraction notice for “Psorinum Therapy in Treating Stomach, Gall Bladder, Pancreatic, and Liver Cancers: A Prospective Clinical Study,” published Dec. 8, 2010 in Evidence-Based Complementary and Alternative Medicine, the paper was plagued by:

Title: Ghanaians Might Be at Risk of Inadequate Dietary Intake of Potassium

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:

Caught Our Notice: An “absolutely perfect retraction”

Via Wikimedia

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 [email protected].
