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

with 2 comments

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 »

Lawsuit couldn’t stop four retractions for diabetes researcher

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.

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.

In his ruling, Judge Timothy Hillman wrote: Read the rest of this entry »

Diabetes researcher won’t give up court fight to quash expressions of concern

Apparently, you can’t keep Mario Saad down.

The researcher, who had 12 figures in a paper corrected this week, was dealt a setback last week when a judge denied his motion to remove expressions of concern on four of his papers in the journal Diabetes, saying that would have amounted to prior restraint — essentially, censorship (a no-no, thanks to the First Amendment).

Saad and his attorneys, however, were undeterred. They filed a motion for reconsideration just four days later, along with a brief, arguing: Read the rest of this entry »

PLoS ONE mega-correction, but no retraction, for researcher who sued diabetes journal

PLoS ONE has just issued a 12-figure correction on a paper by Mario A. Saad, who sued the American Diabetes Association unsuccessfully in an attempt to prevent it from retracting four papers in its flagship journal Diabetes.

The corrections include taking out Western blots copied from another Saad paper, as well as several figures where the bands were “misplaced.”

PubPeer commenters suggest this may not be enough, calling seven additional figures into question. Read the rest of this entry »

American Diabetes Association 1, Mario Saad 0.

As reported by the National Law Journal, a federal judge in Boston has denied Saad’s requests to stop the ADA’s flagship journal, Diabetes, from publishing expressions of concern about four of Saad’s papers, and to prevent the journal from retracting the studies.

Saad filed suit against the ADA on February 5. Judge Timothy Hillman wrote in his order yesterday that approving the researcher’s motion would have violated the right to free speech: Read the rest of this entry »

Publisher and uni go head to head over disputed images in diabetes papers

The State University of Campinas University of Campinas and the American Diabetes Association disagree strongly over how to handle disputed images from faculty member Mario Saad, who is suing the ADA to prevent retraction of his papers.

While the State University of Campinas University of Campinas (Unicamp) acknowledges that 2 of Saad’s papers contain “mistakes”, it concluded there was “not an intention in the actions of the authors,” and the mistakes did not have a negative impact on the scientific community. Ultimately: “the studies published have their own strength, are healthy and were not artificially strengthened by the incorrect images.”

In response, however, Saad’s lawsuit says the ADA asked the school to reinvestigate the articles, and refused to accept any papers from Unicamp faculty in any ADA journals until the issues are resolved.

The ADA has issued four expressions of concern in Saad’s research published in its flagship journal, Diabetes. Saad’s lawsuit aims to prevent the journal from retracting those papers, and asks for monetary compensation.

Retraction Watch has obtained a report of the investigation by Unicamp and Saad’s lawsuit. You can read the full lawsuit here, and the investigation report here.

Here is an excerpt from the Unicamp’s findings: Read the rest of this entry »

Mario A. Saad, who last year retracted a paper for plagiarism, is now suing the American Diabetes Association over four expressions of concern in its flagship journal, Diabetes.

As reported in the Boston Business Journal, Saad’s lawsuit claims that his institution, the State University of Campinas, investigated two articles at the journal’s behest. The American Diabetes Association was unhappy with the results, and asked the school to reopen the investigation, including two additional papers.

Saad is suing to prevent the journal from retracting the papers, in addition to monetary compensation.

Researcher who called plagiarism “the worst type of fraud” retracts paper for…plagiarism

with 33 comments

arq brasAs a reporter on the police beat many years ago, one of us (Adam) used to hang out with a press officer whose desk at the station had the following sign: “Uma boca fechado não recolhe nenhum pé.”

At least, that’s what it would have been had we been in Rio. In Palmer Park, Maryland, the sign read: “A Closed Mouth Gathers No Foot.”

A group of Brazilian researchers has retracted their 2009 article on gut bacteria for plagiarism — but not before one of them decried such behavior as the nadir of scientific misconduct. Read the rest of this entry »
