The notices keep coming for diabetes researcher Mario Saad.
Diabetes has just retracted two more of his papers, both of which had been flagged by expressions of concern, citing problems with duplications. What’s more, the journal added another expression of concern to a 2009 paper on which Saad — based at the University of Campinas in São Paulo, Brazil — is listed as last author, again over concerns of duplication.
This isn’t Saad’s first run-in with the journal: In 2015, the researcher sued the publisher, the American Diabetes Association, after it issued expressions of concern for four of his papers. Later that year, a judge dismissed Saad’s defamation suit. The journal eventually retracted the papers.
The latest articles flagged by Diabetes appear to be part of an intricate publishing web, as the journal suggests all papers have used features of previous papers, and also include elements that have been republished by subsequent articles.
A researcher in Brazil is taking responsibility for accidentally mixing up images in three papers in the Journal of Biological Chemistry.
The corresponding author on the three papers told us the mistake happened because the studies were conducted simultaneously, and relied on one computer.
There’s a side note to these retractions: The co-author list on two papers includes names that should be fairly well-known to our readers — Mario Saad, the researcher who unsuccessfully sued the American Diabetes Association to stop retractions of his papers, and Rui Curi, a researcher whose legal threats assisted in the shutdown of Science-Fraud.org. This makes Saad’s ninth retraction.
According to the retraction notices, Lício Velloso — who, like his co-authors, is based at the University of Campinas in São Paulo, Brazil — assembled all the figures. He told Retraction Watch that the authors initially wanted to correct the papers, adding: Read the rest of this entry »
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.
Mario Saad, a diabetes researcher who once sued to stop a publisher from retracting his papers, has just received his eighth retraction.
Critical Care has retracted a 2012 paper about treating sepsis, citing extensive similarities between figures within the paper and 10 others.
A diabetes researcher who sued to stop a publisher from retracting his papers has just received his seventh retraction.
The latest retraction for Mario Saad, who is based at the University of Campinas (Unicamp) in São Paulo, Brazil, is for a PLOS ONE paper (which was altered last year by a mega-correction). Although an institutional investigation found no evidence of research misconduct, the notice states:
the preparation of the figures falls below the standard of publication and therefore the authors and the editors have agreed that the correct action is to retract the article.
Saad previously sued the American Diabetes Association (ADA) to remove expressions of concern from four of his papers published in the organisation’s flagship journal, Diabetes. However, all four of the papers were later retracted after the suit was dismissed in 2015.
A sixth retraction has appeared for a diabetes researcher who previously sued a publisher to try to stop his papers from being retracted.
Mario Saad‘s latest retraction, in PLOS Biology, stems from inadvertent duplications, according to the authors. Though an investigation at Saad’s institution — the University of Campinas in Brazil — found no evidence of misconduct, a critic of the paper told The Scientist he does not believe that the issues with blots were inadvertent.
Previously, Saad sued the American Diabetes Association to remove four expressions of concern from his papers; they were later retracted, even though Unicamp recommended keeping three of them published.
A journal has added expressions of concern (EOCs) to four papers about diabetes, including one co-authored by an author who previously sued a different journal when it took a similar action on his papers.
The Journal of Physiology flagged the papers after an investigation “could not rule out the possibility” that they contained duplicated Western blots. Though the three other papers do not include Mario Saad on their author list, he plays a role: The papers include blots duplicated from other papers of Saad’s. And they reveal that Saad may have published those blots multiple times in his own work.
The EOCs all start out with the same statement: Read the rest of this entry »
Four expressions of concern in the journal Diabetes have turned into retractions for Mario Saad, a move which he had tried to stop with a lawsuit.
Last August, a judge dismissed Saad’s suit against the American Diabetes Association, which publishes Diabetes, concluding that the expressions of concerns on the papers were not defamation, but part of an “ongoing scientific discourse.” Now, after an investigation at the University of Campinas in Brazil, where Saad is based, and an assessment from an ADA ethics panel (which overturned some of Unicamp’s recommendations), the journal has added to that discourse by turning the EOCs into retractions — and flagging two more of Saad’s papers with EOCs.
Together, the retracted papers have been cited more than 600 times.
As the retraction notes explain, Read the rest of this entry »
Mario Saad can’t catch a break — yesterday, a Massachusetts judge dismissed his defamation suit against the American Diabetes Association, publisher of Diabetes, which published an expression of concern regarding four of his papers in March.
The researcher has tried — and failed — to use the courts to remove the EoC.
In Saad’s latest attempt to employ legal action against the journal — arguing the EoC was defamatory — the United States District court of Massachusetts was clear in its ruling (which you can view in its entirety here):
It hasn’t been a good week for scientists going to court to silence criticism of their work.
Yesterday, PubPeer won a near-complete victory in a case seeking the identities of their commenters. And also yesterday, a Massachusetts judge struck down — for the second time — a request by Mario Saad to remove expressions of concern about four of his papers in Diabetes.
