What Caught Our Attention: Cornell food marketing researcher Brian Wansink, the one-time media darling who has been dogged by mounting criticism of his findings, has lost another paper to retraction. As we’ve noted in the past, corrections for Wansink’s work tend to be long. This time, “the number of errors is too voluminous to be executed by issuing a correction statement,” according to the retraction notice for a paper about behaviors following weight loss surgery. Continue reading Caught Our Notice: Retraction eight as errors in Wansink paper are “too voluminous” for a correction
What Caught Our Attention: When the New England Journal of Medicine (NEJM) publishes a correction that is more than a misspelling of a name, we take a look. When NEJM publishes a 500-word correction to the data in a highly cited article, we take notice. This study tested the effects of a drug to prevent blood loss in patients undergoing heart surgery; it’s been the subject of correspondence between the authors and outside experts. The correction involved tweaks — lots of tweaks — to the text and tables, which did not change the outcomes. Continue reading Caught Our Notice: Big journal, big correction
A medical journal has retracted a 2016 paper over a series of errors, prompting it to lose faith in the paper overall. The authors have objected to the decision, arguing the errors weren’t their fault and could be revised with a correction — rather than retracting what they consider “an important contribution” to an ongoing debate in medicine.
The paper explored the so-called weekend effect—that patients admitted to the emergency department on the weekend are more likely to die than those admitted on a weekday. Whether the weekend effect is real is not clear. Some studies have supported the phenomenon in certain areas of medicine, but others (including the now-retracted paper) have failed to find an effect.
First author Mohammed A. Mohammed, based at the University of Bradford in the UK, told Retraction Watch that the errors were introduced by one of the hospitals that provided them the data:
The decision by KI’s vice chancellor will be followed by a request to retract the paper, published by the journal Respiration.
In the paper, the researchers described the case of a man with an acute lung disorder, in which he received an experimental treatment involving the use of his own blood-derived cells and the drug erythropoietin, which stimulates the production of red blood cells. The patient “demonstrated an immediate, albeit temporary, clinical improvement,” according to the authors. However, he ultimately died of multisystem organ failure.
A journal has retracted a 2014 paper because of an authorship dispute that became the subject of litigation.
Last year, the Allegheny Health Network in Pittsburgh requested the paper be retracted to resolve the dispute. The Journal of Applied Biomaterials & Functional Materials retracted the paper in October.
According to the retraction notice, the principal investigator of a clinical trial on which some of the study is based was not included as a co-author, and claimed he had not “validated the accuracy of the data.”
The notice does not mention a lawsuit, but a letter from the authors’ research institution does.
What Caught Our Attention: Robert J. Frumento first caught our notice in 2013, as a coauthor on a paper retracted with a nonspecific reference to author misconduct. Three years later, Frumento was clearly identified as having fabricated data and a master’s degree, and added three retractions to his name. Now he’s got a fifth retraction, this one citing missing data and a lack of proof that data blinding was performed correctly. Continue reading Caught Our Notice: Columbia researcher up to five retractions
Journals are raising ethical concerns about the research of a doctor who offers controversial embryonic stem cell treatments.
Two journals have issued expressions of concern for three papers by Geeta Shroff, who was the subject of a 2012 CNN investigative documentary. All cite ethical concerns; one mentions the potential link between the procedure the authors describe and a risk of forming teratomas, a type of tumor. Shroff has objected to all three notices.
Shroff, a doctor offering controversial embryonic stem cell treatments at her New Delhi clinic, Nutech Mediworld, has said that for years she couldn’t find opportunities to present her research to the medical community.

According to journal’s editor, Keith Lillemoe, the papers—published in 2015, two months apart—had undergone full peer review and were rejected, “like 90% of submissions to our journal:”
The decision was clear and the authors were notified.
But somehow, Lillemoe said, “our publishing team mistakenly published the papers and placed them into [e-pub] status totally unbeknownst to the editorial team.”
The authors of one paper told us they were unhappy with how the journal handled the situation.
The Annals of Emergency Medicine has republished a controversial paper it withdrew earlier this year which compared the cost of emergency care at different types of facilities.
Because the paper drew heavy criticism when it was originally released, the journal has published a revised version, along with several editorials and discussions between the authors and critics. One point of contention: The analysis stems from data provided by an insurance company — Blue Cross Blue Shield — which it declined to share.
The paper — originally published in February — caught national attention (and raised concerns among some emergency care providers) when it reported the cost of treatment in emergency departments can be significantly higher than at urgent care centers, even for the same conditions. The journal withdrew the paper in spring, and re-published it Tuesday, with minor changes.
First author Vivian Ho at Rice University told us she made “slight changes” to some headings, phrases, and the appendix, but:
The Annals of Surgery has retracted a paper that used only male pronouns to describe surgeons following outcry from readers.
The journal plans to replace the article — a recent presidential address of the European Surgical Association — with a new version with more “gender inclusive language.”
The problem, said editor Keith D. Lillemoe, is that the address was delivered in April by previous ESA president Marek Krawczyk in Polish. According to an email Krawczyk sent to ESA leadership, which Lillemoe forwarded to us, Krawczyk says the pronoun “his” can include women in Polish.
Still, Lillemoe told us, the journal believed it needed to quickly retract the paper:
