Update on Fujii: Anesthesia journal finds overwhelming statistical evidence of data fabrication

There’s a bit more this afternoon on the story of Yoshitaka Fujii, the Japanese anesthesiologist accused of fraud and other misconduct that we reported on yesterday. The British journal Anaesthesia, which has been looking into Fujii’s research record, has posted four articles and editorials about the case and related issues on its website. One in … Continue reading Update on Fujii: Anesthesia journal finds overwhelming statistical evidence of data fabrication

The new retraction record holder is a German anesthesiologist, with 184

The German anesthesiologist Joachim Boldt has lost 20 more papers since January 2023, earning him the top spot in our leaderboard, with 184 retractions.  Boldt, readers may recall, was once one of the leading international figures in perioperative medicine. His work, particularly studies involving the use of fluid management during surgery, helped inform clinical guidelines … Continue reading The new retraction record holder is a German anesthesiologist, with 184

Four years after anesthesiology society’s request, four articles remain unretracted

Three years ago, we wrote that the Japanese Society of Anesthesiologists had in 2017 asked several journals to retract a total of nine papers by Yuhji Saitoh, formerly of Yachiyo Medical Center and Tokyo Women’s Medical University.  According to the society, Saitoh had committed ethics violations in 10 articles, three of which had already been … Continue reading Four years after anesthesiology society’s request, four articles remain unretracted

Meet a sleuth whose work has led to the identification of hundreds of fraudulent papers

Last month, Retraction Watch reported on the case of Hironobo Ueshima, an anesthesiology researcher found guilty of misconduct in more than 140 papers. A journal editor, John Loadsman, was the first to suspect there were issues in Ueshima’s work. But this was hardly the first time Loadsman had been the canary in the coal mine … Continue reading Meet a sleuth whose work has led to the identification of hundreds of fraudulent papers

Anesthesiology researcher guilty of misconduct in more than 140 papers: Investigation

A Japanese anesthesiologist has been found guilty of fabricating data and other misconduct in 142 articles, leading to his termination and the sanction of several of his co-authors.  Showa University says its investigation into Hironobu Ueshima, the existence of which we first reported on last June, found that the prolific researcher had doctored his results, … Continue reading Anesthesiology researcher guilty of misconduct in more than 140 papers: Investigation

“We didn’t want to hurt them. We are polite”: When a retraction notice pulls punches

A group of anesthesiology researchers in China have lost their 2020 paper on nerve blocks during lung surgery after finding that the work contained “too many” errors to stand. But after hearing from the top editor of the journal, it’s pretty clear “too many errors” was a euphemism for even worse problems. The article, “Opioid-sparing … Continue reading “We didn’t want to hurt them. We are polite”: When a retraction notice pulls punches

Researchers face disciplinary action as dozens of their studies fall under scrutiny

A group of obstetrics researchers in the Middle East is facing disciplinary action after questions were raised about the validity of the data in dozens of their published studies.  The tale — involving contaminated clinical trials, potentially fabricated PhDs, findings of misconduct that went ignored, accusations of terrorist sympathies and unresponsive journals — requires some … Continue reading Researchers face disciplinary action as dozens of their studies fall under scrutiny

Prolific anesthesiologist in Japan has two papers retracted

A journal has retracted two case reports by a prolific Japanese anesthesiologist who appears to be embroiled in a misconduct investigation.  The two case studies, in JA Clinical Reports, were written by Hironobu Ueshima and Hiroshi Otake, of  Showa University Hospital in Tokyo. Ueshima has roughly 170 publications to his name, according to Google Scholar, … Continue reading Prolific anesthesiologist in Japan has two papers retracted

Zombie papers: Why do papers by the most prolific fraudster in history keep getting cited?

It’s a bit like a slugger crediting Barry Bonds for help with his homerun swing. An anesthesiology journal has retracted a 2018 paper that cited three retracted papers by Yoshitaka Fujii, the record-holder for most retractions by a single author.  As we’ve written before, journals had a spotty record in reacting to the Fujii scandal, … Continue reading Zombie papers: Why do papers by the most prolific fraudster in history keep getting cited?

Anesthesiologist joins the 100-retraction club

Until this year, only one researcher — Yoshitaka Fujii — had eclipsed the century mark for retractions. But Fujii can no longer claim dibs on being the only scientist to lose three digits worth of papers.  Joachim Boldt, a fellow anesthesiologist fraudster, recently notched three more retractions, bringing his tally, by our count, to an … Continue reading Anesthesiologist joins the 100-retraction club
