Journal flags two more papers by diabetes researcher who sued to stop retractions (and now has 12)

with one comment

A diabetes journal has issued two notices of concern for papers co-authored by a researcher who took another publisher to court after it did the same thing — but ultimately lost.

The notices are for two papers co-authored by Mario Saad — who, after losing his legal battle with the American Diabetes Association, has since accumulated 12 retractions. Both notices — from the journal Diabetologia, published by Springer and the the European Association for the Study of Diabetes (EASD) — say they have alerted Saad to their concerns about some of the images in the papers, and the university where he is based was asked to investigate more than one year ago. Since the journal has not yet received any information from the University of Campinas in Brazil, however, it decided to issue expressions of concern for the two papers.

Here’s the text of the first notice:

Researcher who sued to prevent retractions now has 12

with one comment

A diabetes researcher who once sued a publisher to prevent several retractions has just issued his 12th.

The latest retraction, like several others for Mario Saad, appears in the journal Diabetes. Although in the past Saad expended considerable effort to protect four other Diabetes papers from this same fate, the latest retraction was initiated by the authors, citing several duplicated images. The American Diabetes Association had flagged the 2009 paper with an expression of concern earlier this year.

In 2015, Saad brought a lawsuit against the ADA, claiming that it “wrongfully published” four expressions of concerns in its flagship journal Diabetes, in an attempt to prevent the papers from being retracted. He lost, and the papers were retracted in 2016.

The lawsuit also did nothing to deter the ADA from flagging other potentially problematic papers with expressions of concerns, including the latest 2009 Diabetes paper, on which Saad is last and corresponding author.  Read the rest of this entry »

Journal flags another paper by diabetes researcher who sued to stop retractions

without comments

It would seem that resorting to legal means to avoid editorial notices doesn’t always work.

We’re coming to that conclusion after seeing yet another notice for Mario Saad, based at the University of Campinas in São Paulo, Brazil. In this case, it’s an expression of concern from the Journal of Endocrinology, on a 2005 paper that lists Saad as the second-to-last author. According to the notice, the journal is concerned the paper contains spliced and duplicated images; although the authors offered to repeat the experiments, the journal considered that potential delay “unacceptable.”

Despite Saad’s legal efforts, he is now up to 11 retractions, along with multiple expressions of concern.

Here’s the full text of the notice (which is paywalled, tsk tsk):

Researcher sued to stop retractions; he just earned two more and is now up to 11

without comments

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.

Here’s the first retraction notice, for “A Central Role for Neuronal AMP-Activated Protein Kinase (AMPK) and Mammalian Target of Rapamycin (mTOR) in High-Protein Diet–Induced Weight Loss:”

Researcher logs three retractions for image duplications — two of which with familiar co-authors

with one comment

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 »

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

Mario Saad

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.

Researcher who sued to stop retractions earns his 7th

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.

Here’s the new retraction notice, issued July 8: Read the rest of this entry »

Researcher who sued to stop retractions gets his sixth

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.

Researcher who unsuccessfully sued journal to stop retractions earns another expression of concern

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 »
