A shadow was cast on a bone researcher’s work. What are journals doing about his papers?

Last year, a researcher cast doubt on a bone scientist’s clinical trials, suggesting some of the findings may not be legitimate. So what’s happened since?

Since 2015, journals have retracted 14 papers by bone researcher Yoshihiro Sato, based at Mitate Hospital in Japan, for issues ranging from self-plagiarism, to problems with data, to including co-authors without their consent. (We covered the latest two retractions this week.) Last year’s analysis identified patterns in more than 30 of Sato’s clinical trials that suggest systematic problems with the results. (Sato has defended his research.)

With doubts cast on Sato’s body of work, we contacted the journals that have published his papers involving human trials, to see if any taken another look at Sato’s work; several responded. While most believe there is little reason to take further action at this time, some told us they are investigating.

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

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

Journal pulls abstract author didn’t submit

A journal has retracted an abstract after discovering the author didn’t submit it — and also because it appears “highly similar” to a previous publication in Chinese.

The abstract was presented at the 2nd International Conference on Biomedicine and Pharmaceutics in 2014, and lists Qing Guo as the sole author, based Wuhan, China at the China University of Geosciences.

According to the retraction notice, published in the Journal of Investigative Medicine last December, the organizer of the conference discovered Guo hadn’t consented to publish the abstract — moreover, it appeared to overlap with another article in Chinese, written by different authors: Continue reading Journal pulls abstract author didn’t submit

Author of retracted math paper defends against plagiarism charge, threatens to sue journal

A researcher in Egypt is threatening to sue a mathematics journal if it doesn’t un-retract one of his papers.

The American Journal of Computational Mathematics in May retracted Mostafa M. A. Khater‘s 2015 paper, “The Modified Simple Equation Method and Its Applications in Mathematical Physics and Biology.” The retraction notice is sparse on the details, indicating only that the article was not up to snuff: Continue reading Author of retracted math paper defends against plagiarism charge, threatens to sue journal

Doing the right thing: Authors pull psych review after finding inaccuracies

Two psychology researchers are retracting a meta-analysis after discovering errors they believe may affect the conclusions.

We’re giving this a “doing the right thing” nod, as last author Pankaj Patel of Villanova University in Pennsylvania contacted us about his plan to retract the paper, and resubmit for publication once he and co-author Sherry Thatcher — at the University of South Carolina — have performed all their recalculations.

Here’s the retraction notice for “Demographic faultlines: A meta-analysis of the literature,” published in the Journal of Applied Psychology: Continue reading Doing the right thing: Authors pull psych review after finding inaccuracies

Judges toss lawsuits by CrossFit gym claiming fraud in $273 million in grants

court caseFederal judges in Ohio have dismissed two lawsuits claiming that university researchers used false results to secure more than $250 million in federal grants.

Both lawsuits, which objected to a study examining the effects of CrossFit-based training, were filed by Mitchell Potterf, the owner of a gym affiliated with CrossFit in Columbus, Ohio. Potterf took issue with a 2013 study by researchers at Ohio State University (OSU) that was conducted at his gym.

Potterf filed one suit against the OSU researchers and a second against the National Strength and Conditioning Association (NCSA). The NSCA publishes the Journal of Strength and Conditioning Research, where a paper about the study appeared. The article, “Crossfit-based high-intensity power training improves maximal aerobic fitness and body composition,” has been cited 15 times, according to Thomson Reuters Web of Science.

The study followed 43 men and women as they completed 10 weeks of CrossFit-based training. In addition to those 43 participants, 11 dropped out before completing the regimen. According to the original paper: Continue reading Judges toss lawsuits by CrossFit gym claiming fraud in $273 million in grants

Meet the researcher with 13 retractions who’s trying to sue PubPeer commenters: Fazlul Sarkar

Fazlul Sarkar
Fazlul Sarkar

Fazlul Sarkar has not had a good month: In the last few weeks, he has earned 13 retractions across four journals, the latest in the fallout from a string of legal cases that have pitted him against one of science publishing’s major players.

Sarkar gained attention in 2014 when he sued anonymous commenters of PubPeer for defamation, and for potentially costing him a new gig at the University of Mississippi. But before all that, he was a respected researcher with hundreds of published papers, 38 of which were cited at least 100 times each. He’d also received $12.8 million in NIH funding for his research. So how did it all fall apart?

With the involvement multiple lawsuits, multiple institutions, and multiple people — some of whom are anonymous — it can get complex trying to keep track of it all. So for your convenience, we’ve compiled a timeline of recent events in the case: Continue reading Meet the researcher with 13 retractions who’s trying to sue PubPeer commenters: Fazlul Sarkar

You’ve been dupe’d: Results so nice, journals published them twice

With so many retraction notices pouring in, from time to time we compile a handful of straight-forward retractions.

Once again, this list focuses on duplications — but unlike other duplications, these authors were not at fault. Rather, these retractions occurred because the publishers mistakenly published the same paper twice — the result of a transfer between publishers, for instance, or accidentally publishing the unedited version of the paper. We’re forced to wonder, as we have before, whether saddling researchers’ CVs with a retraction is really the most fair way to handle these cases.

So without further ado, here’s five cases where the journal mistakenly duplicated a paper, and had to retract one version: Continue reading You’ve been dupe’d: Results so nice, journals published them twice

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”
