Details of investigative report into Sarkar released by ACLU

We knew that Wayne State University had investigated allegations of misconduct against Fazlul Sarkar, the scientist who is suing PubPeer commenters over criticisms of his work. We knew The Scientist had obtained a copy of the report, which concluded he had engaged in widespread misconduct, and he should retract more than 40 papers.

And now, thanks to the American Civil Liberties Union, which is representing PubPeer in court and has filed a motion to include the report as evidence in the case, we have a copy.

It’s a long read, but here are some highlights:

Authors retract paper lacking approval to study asthma in athletes

british-journal-of-sports-medicineThe authors of a 2014 study about asthma in Norwegian athletes have retracted it after realizing they hadn’t obtained proper approval from an ethical committee.

The study’s first and corresponding author of the study in the British Journal of Sports Medicine — Julie Stang from the Norwegian School of Sports Sciences in Oslo — told us the authors had struggled to obtain ethical approval for the research, but believed the issue had been resolved.

However, earlier this year, a member of an ethical committee wrote an article in the Norwegian press about his concerns regarding the study, which tested the effects of three drugs on top athletes’ breathing. In it, he said the Regional Committees for medical and health professional research ethics (REC) had not approved the study, as members were concerned the presumably healthy athletes were being exposed to drugs used to treat asthma, which could enhance their performance. 

Stang has denied that the study had anything to do with boosting athletic performance.

Stein Evensen, the committee member who wrote the article, declined to comment beyond the published text. So we’ve gotten the kronikk article translated from Norwegian using One Hour Translation. It reads: Continue reading Authors retract paper lacking approval to study asthma in athletes

Authors pull two papers about faulty glucose meters after industry prompts

4.coverTwo papers evaluating glucose meters — used by diabetics to monitor blood sugar levels — suggested that a couple of the devices don’t work as well as they should. Perhaps unsurprisingly, the companies that sell those meters objected to how the studies were conducted. By all accounts, the companies appear to be justified in their complaints.

In both cases, researchers used blood drawn from veins to test the meters. But manufacturers of the WaveSense JAZZ and GlucoRx glucose meters said their devices are designed to work with fresh blood from a finger-prick. Both papers have now been retracted.

The retraction notice for “Technical and clinical accuracy of five blood glucose meters: clinical impact assessment using error grid analysis and insulin sliding scales,” published in 2015 in the Journal of Clinical Pathology, hints at the issue:

Nature Cell Bio paper may be headed for retraction

ncbA Nature Cell Biology paper published only a few months ago by prominent researchers in Taiwan has sparked a heated discussion on PubPeer, which now includes a comment allegedly from an author saying they have requested its retraction.

Although a representative of the journal wouldn’t confirm to us that the authors had requested a retraction, the comment on PubPeer says the paper contains several figures that were “inappropriately manipulated” by the first author.

Here’s the full comment on PubPeer, tagged as coming from one of the authors of the paper:

New funding for researcher who sued to stop retractions (and now has 8)

A diabetes researcher with eight retractions — despite his attempts to block some in court — has received a new batch of research funding.

According to a release from public funding agency Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), Mario Saad is among 33 researchers who will receive funding from partnerships between federal and state agencies, including FAPESP.

It’s unclear how much Saad’s project will individually receive, but the total for all projects exceeds 640 million Brazilian Real, equivalent to $185 million USD.

Saad’s name should be familiar to our readers.

Two Harvard-led groups pull well-cited cancer papers for duplication

the-journal-of-clinical-investigationTwo sets of authors based largely at Harvard Medical School have each retracted a paper for duplication in the same journal.

Both papers — which are more than a decade old — were pulled in The Journal of Clinical Investigation on November 1 by their respective corresponding authors.

One paper’s last author told us it was difficult to identify how the duplications occurred since the study took place so long ago, but added that multiple experiments had corroborated the results.

Here’s the first retraction notice for “Complementary roles of IRS-1 and IRS-2 in the hepatic regulation of metabolism:” Continue reading Two Harvard-led groups pull well-cited cancer papers for duplication

Prominent researcher in Scotland resigns after misconduct finding upheld

Robert Ryan

A rising star in the field of infectious disease has resigned from the University of Dundee in Scotland after the university upheld the findings of an investigation concluding that he committed misconduct.

Earlier this year, Robert Ryan was suspended amidst the investigation, which focused on data doctoring in several publications. We’ve now been forwarded an internal email from Julian Blow, dean of the School of Life Sciences, which alerts staff that Ryan has resigned, and the institution has upheld its finding of misconduct, despite Ryan’s appeal.

In 2015, Ryan was selected to be an EMBO Young Investigator; yesterday, EMBO announced that it had withdrawn him from the program.

Blow’s email to staff, dated November 9, states:

Official notice published for chem paper slated for retraction in 2011

process-safetyAfter five years, Elsevier has finally issued a notice of retraction for a paper it announced it was pulling for fraud in 2011.

All of the papers were produced by a research group in Brazil; all were retracted after the publisher conducted an investigation, concluding that the NMR results had been manipulated. At the time, the last author on the latest retraction, Claudio Airoldi, defended the work. Since then, however, Airoldi has logged two more retractions, bringing his total to 13.

Here’s the full text of the retraction notice, from Process Safety and Environmental Protection: Continue reading Official notice published for chem paper slated for retraction in 2011

Researcher denies faking reviews for 5 newly retracted papers

engineering-failure-analysisJournals have retracted five papers by a materials researcher based in Poland after concluding the peer-review process had been faked. 

According to the retraction notices — which all appear in Elsevier journals and contain the same text — the papers were accepted due to “positive advice of at least one faked reviewer report,” which were submitted from fictitious email accounts for reviewers suggested by the author.

All five studies were solely authored by Mariusz Książek, who is based at the Wrocław University of Science and Technology in Poland, and has denied any wrongdoing.

A spokesperson from the Wrocław University of Science and Technology confirmed that the university “has taken legal actions.” 

Książek told Retraction Watch why he doesn’t agree with the decision to retract his papers: Continue reading Researcher denies faking reviews for 5 newly retracted papers

Analysis casts doubt on bone researcher’s body of work

19-coverA new analysis of more than 30 clinical trials co-authored by a bone researcher based in Japan is casting doubt on the legitimacy of the findings.

Yoshihiro Sato, based at Mitate Hospital, has already retracted 12 papers, for reasons ranging from data problems, to including co-authors without their consent, to self-plagiarism. Most of these retracted papers are included in the analysis in the journal Neurology, which concluded that Sato’s 33 randomized clinical trials exhibited patterns that suggest systematic problems with the results.

Other researchers have used similar approaches to analyze a researcher’s body of work — notably, when John Carlisle applied statistical tools to uncover problems in the research of notorious fraudster Yoshitaka Fujii, and Uri Simonsohn, who sniffed out problems with the work of social psychologist  Dirk Smeesters.

Author Mark Bolland of the University of Auckland told us he was surprised by his findings: Continue reading Analysis casts doubt on bone researcher’s body of work
