Co-author of retraction record-holder likely fabricated his own data, analysis shows

In 2012, John Carlisle, a British anesthesiologist, demonstrated conclusively using statistics that Yoshitaka Fujii had faked data in many studies. Fujii — as followers of this blog well know — now holds the record for most retractions by an individual author (183).

Carlisle’s work accomplished two things: It put to rest any doubt that problems with Fujii’s work might have resulted from innocent mistakes, and it gave journals a mathematical tool for conducting investigations into potential cases of misconduct.

Now comes the payoff. In a new paper, Carlisle and another anesthesiologist, John Loadsman, take aim at one of Fujii’s frequent co-authors, Yuhji Saitoh of Yachiyo Medical Center and Tokyo Women’s Medical University in Japan. The pair analyzed data from 31 studies Saitoh published between 1993 and 2012 — including one study that was rejected in 2015 — for a total of 32 papers. Of those, 23 did not include Fujii as an author.

Writing in the journal Anaesthesia, where Carlisle published his first study about Fujii, he and Loadsman state that: Continue reading Co-author of retraction record-holder likely fabricated his own data, analysis shows

Karolinska requests retraction of 2014 Macchiarini paper

Paolo Macchiarini

It has been a tough couple of years for surgeon Paolo Macchiarini, once lauded for pioneering a groundbreaking procedure to transplant tracheas.

After a series of documentaries prompted his former employer, Karolinska Institutet (KI), to reopen a misconduct investigation against him, KI has today released one verdict regarding a 2014 Nature Communications paper: guilty.

KI said it is contacting the journal to request a retraction of the paper, which has already been flagged with an expression of concern.

Here’s more from a release from the institution: Continue reading Karolinska requests retraction of 2014 Macchiarini paper

Catching up: Publisher to pull four papers by retraction record holder flagged years ago

the-laryngoscopeJournals published by Wiley are retracting four papers by Yoshitaka Fujii, the anesthesiology researcher with the most retracted scientific papers.

Retraction Watch readers will be familiar with Fujii’s case: He currently holds the number one spot on our leaderboard with more than 180 retractions, some of which are pending. (That’s nearly twice the number of retractions by the researcher in the #2 spot, Joachim Boldt.) 

Earlier this year, The Breast Journal and The Laryngoscope — both of which are published by Wiley-Blackwell — issued expressions of concern (EOCs) for a total of four papers by Fujii. All four papers were included in a 2012 analysis of 168 of Fujii’s studies by J. B. Carlisle, a consultant anesthetist in the UK, who concluded that the chance of much of Fujii’s data appearing the way it does naturally is

…the chance of selecting one particular atom from all the human bodies on earth.

Now, both journals are retracting the papers. 

A Wiley spokesperson told us: Continue reading Catching up: Publisher to pull four papers by retraction record holder flagged years ago

Researchers retract two well-cited papers for misconduct

A scientist in Germany has lost two papers that were collectively cited more than 500 times, after an investigation at her former university found her guilty of scientific misconduct.

The probe into Tina Wenz by the University of Cologne in Germany, her former employer, recommended that six of her papers — which have induced some chatter on PubPeer — should be retracted. One of these papers was pulled by Cell Metabolism last year. Now, Cell Metabolism has pulled another of Wenz’s papers, and she has also lost another study published in the Proceedings of the National Academy of Sciences (PNAS), which was previously corrected. 

First, here’s the PNAS retraction notice, issued today: Continue reading Researchers retract two well-cited papers for misconduct

Bone researcher with lifetime funding ban earns third retraction

via WCH

A researcher who received a lifetime funding ban for misconduct from a Canadian agency has logged her third retraction, after a re-analysis of her work unveiled “serious inconsistencies.”

In July, the Canadian Institutes of Health Research (CIHR) released a report about Sophie Jamal, following an investigation by her former employer, The Women’s College Hospital in Toronto, Canada. The probe concluded that Jamal had manipulated data, which resulted in her being banned from CIHR funding for life, and the retraction of a study in The Journal of the American Medical Association.

After that retraction, researchers that made up the the Canadian Multicentre Osteoporosis Study Group (CaMos) decided to take a second look at Jamal’s work. In August, we reported on a retraction that came out of that examination, in the American Journal of Kidney Diseases (AJKD). At the time, a senior researcher from the group told us the group had also requested another journal retract a CaMos paper. 

Now, that other retraction has appeared. Here’s the retraction notice Osteoporosis International issued earlier this month: Continue reading Bone researcher with lifetime funding ban earns third retraction

Oops: Supposedly untreated cancer patients had surgery, after all

gmrThe first author of a 2016 paper has retracted it after realizing that all the lung cancer patients that were supposed to have been untreated did, in fact, have surgery to remove their tumors. 

Zhao Kai, the study’s first author from the Qilu Hospital of Shandong University and Zibo Central Hospital (both in China), took full responsibility for the error.

Here’s the retraction notice, published last month in Genetics and Molecular Research: Continue reading Oops: Supposedly untreated cancer patients had surgery, after all

High-profile Science paper retracted for misconduct

Science has retracted a high-profile immunology paper after a probe concluded the corresponding author had committed misconduct.

The paper — which initially caught media attention for suggesting a protein could help boost the immune system’s ability to fight off tumors — has been under a cloud of suspicion since last year, when the journal tagged it with an expression of concern, citing a university investigation.

That investigation — at Imperial College London — has concluded that the paper contained problematic figures that were the result of research misconduct. All were prepared by last and corresponding author Philip Ashton-Rickardt, who took full responsibility. Even though the paper was published in 2015, some original blots and accompanying details have disappeared.

Today, the journal released a retraction notice: Continue reading High-profile Science paper retracted for misconduct

Journal pulls cancer paper that used others’ data; authors MIA

A journal has retracted a paper after a reader pointed out some of the data looked familiar — and the authors never responded to the allegations.

According to the retraction notice in the International Journal of Molecular Medicine, the reader showed the journal that the histological data in two of the figures were from another published paper by different researchers. But when the journal contacted the authors on several occasions, they didn’t hear back. 

Here’s the retraction notice: Continue reading Journal pulls cancer paper that used others’ data; authors MIA

We’re not “citation police:” No more errata for omitted citations, says economics journal

An economics journal has corrected a paper for the second time for failing to cite previous studies — and said in a separate note that it no longer plans to publish similar errata, with rare exceptions. 

In September 2015, we reported on the first erratum for “Incentives for Creativity” — a paper that analyzed ways of inspiring creativity in the workplace — after it failed to cite relevant papers. One year on, the same paper has another erratum for a similar reason: not citing relevant papers from another field.

You don’t often see two errata for the same mistake — omitted citations — on one paper. Even less often do you see journal editors co-publishing a note saying they don’t plan on issuing any more such notices. Here’s an excerpt from the editor’s note in Experimental Economics: Continue reading We’re not “citation police:” No more errata for omitted citations, says economics journal

Spam me once, shame on you. (Academic) spam me 3000 times…?

Every year, academics get thousands of spam emails inviting them to submit manuscripts or attend conferences — but don’t bother asking to “unsubscribe” for Christmas.

Spoiler alert, for those of you planning to read the rest of this post: It doesn’t make much of a difference.

That’s according to the conclusions of a study published in one of our favorite issues of the BMJ  — the Christmas issue. After a group of five self-described “intrepid academics” tried to unsubscribe from the 300+ spam invitations they received on average each month, the volume decreased by only 19% after one year.

Not surprisingly, many emails — approximately 1 in 6 — were duplicates (aka “reheated spam”), and the vast majority (83%) had little relevance to the researchers’ interests.

Study author Andrew Grey at the University of Auckland told us that since it’s the BMJ Christmas issue, they wanted to have a bit of fun. But it’s not an all-together light topic, he noted: Continue reading Spam me once, shame on you. (Academic) spam me 3000 times…?
