Medical journal retracts letter calling hijab ‘an instrument of oppression’

A major Canadian medical journal has retracted a letter to the editor by a prominent surgeon in Quebec who expressed reservations about a photo the journal had published of two young girls, one of whom was wearing a hijab.

The photo in question (above) ran on the cover of the November 8, 2021 issue of the Canadian Medical Association Journal.The image prompted a letter from Sherif Emil, an endowed chair of surgery at Montreal Children’s Hospital of McGill University. Published December 20, the letter voiced concern that the photograph used “an instrument of oppression [the headcovering] as a symbol of diversity and inclusion.” (That’s in the title of the letter, which the journal now acknowledges writing, not Emil.)

As the CBC reported, Emil wrote that:

Harvard journal retracts paper on Black advocacy in elections

The Harvard Kennedy School’s Misinformation Review has retracted an article which claimed – or misclaimed, as the case may be – that an African American advocacy movement discouraged Blacks from voting for Democratic politicians and suppressed news about the Covid-19 pandemic.

The article, “Disinformation creep: ADOS and the strategic weaponization of breaking news,” appeared in the Special Issue on Disinformation in the 2020 Elections published in January by the Kennedy School’s Shorenstein Center on Media, Politics, and Public Policy.

ADOS is short for American Descendants of Slavery, an online movement that calls for reparations for slavery in the United States. The movement – which uses the hashtag #ADOS on social media – was founded by Yvette Carnell and Antonio Moore.

The article was written by Mutale Nkonde, the founding CEO of AI For the People, and co-authors including several affiliated with MoveOn, a progressive political organization.

According to the abstract of the paper, which is no longer available online:

AHA journal tones down abstract linking COVID-19 vaccines to risk of heart problems

The American Heart Association has published a corrected version of a controversial meeting abstract which claimed to show that Covid-19 vaccinations “dramatically” increased a person’s risk for serious heart problems.

The study was the work of Stephen Gundry, a cardiac surgeon who now sells dietary supplements of questionable efficacy on his website. Gundry also sees patients at the Center for Restorative Medicine and International Heart & Lung Institute in California and offers advice on YouTube.

Gundry submitted the abstract, titled “Mrna COVID Vaccines Dramatically Increase Endothelial Inflammatory Markers and ACS Risk as Measured by the PULS Cardiac Test: a Warning,” to the AHA’s 2021 scientific meeting, which apparently accepted it without much, if any, review.

At the end of November, after fielding complaints about the study, the AHA issued an expression of concern for the abstract, which was riddled with spelling errors – including calling the PULS test the “PLUS” test in the first sentence, where any reader could immediately spot the mistake – and other problems:

Researchers ‘devastated’ after finding manipulated data in study of pediatric brain tumors

An international group of cancer researchers has lost an influential 2020 paper in Nature Neuroscience after finding problems with the data that triggered an institutional investigation.

The article, “Tumor necrosis factor overcomes immune evasion in p53-mutant medulloblastoma,” represented a potentially major advance in the treatment of pediatric brain tumors, according to Robert Wechsler-Reya, the director of the Tumor Initiation & Maintenance Program at the Sanford Burnham Prebys Medical Discovery Institute, in La Jolla, Calif., and the senior author of the paper, which has been cited 17 times, per Clarivate Analytics’ Web of Science:

Two expressions of concern arrive for papers linked to beleaguered biotech Cassava

The Journal of Neuroscience has slapped expressions of concern on a pair of papers linked to the maker of a controversial drug to treat Alzheimer’s disease.

As we and others have reported, Cassava Sciences has been under intense scrutiny lately. In August, the law firm Labaton Sucharow – who is representing Cassava short sellers – submitted a “citizen’s petition” to the FDA regarding a regulatory filing from the company for its drug simulfilam and called on the agency to halt trials of the experimental medication because it had:

Exercise researcher earns more retractions as investigations mount

Co-author James Steele, one of the sleuths who brought the issues to attention

Retractions are slowly stacking up for an exercise researcher in Brazil whose work has come under scrutiny by data sleuths, including a couple of his erstwhile co-authors. The concerns prompted an investigation by his former institution into one of his academic supervisors, who may be facing sanctions, Retraction Watch has learned.

In June 2020, the sleuths posted a preprint calling for the retraction of seven papers by the researcher, Matheus Barbalho, a PhD student at the Centro de Ciências Biológicas e da Saúde, part of the Universidade da Amazônia, in Belém. The reason, according to the sleuths – who included James Steele and James Fisher, of Solent University in the United Kingdom, both of whom were co-authors on papers with Barbalho: the data were, in their view “atypical, improbable, and to put it bluntly, pretty weird.”

Since then, journals have retracted two of Barbalho’s papers (he had lost one in April 2020), citing concerns about the data in the articles.

Paper retracted because authors ‘misrepresented a published theoretical model as if they had found it’

A physics journal has retracted a 2017 paper after learning that the authors had tried to pass off the ideas of others as their own.

Normally, we’d just call that a case of plagiarism and move on. But in this case, the charge goes a bit deeper – less cribbing a few lines of the Principia and more claiming to have discovered gravity.

“Exploring multiband tunneling for uncoupled particles: A polynomial view,” was written by a group of a half-dozen researchers in Mexico City, Uruguay and Cuba, where senior author Leo Diago-Cisneros sits on the faculty of the University of Havana.

The paper, which appeared in the Journal of Applied Physics, purported to describe:

Paper on canine gastrointestinal illness dogged by lack of disclosures

A veterinary journal has retracted — in a big way — a 2021 paper about bowel disease in dogs by a group of authors who failed to disclose key conflicts of interest and then appear to have lied about the omission when pressed.

The article, “Utility of the combined use of 3 serologic markers in the diagnosis and monitoring of chronic enteropathies in dogs,” appeared in the Journal of Veterinary Internal Medicine, an official title of the American College of Veterinary Internal Medicine.

The first author was Juan Estruch, of Vetica Labs, a rather opaque company based in San Diego and of which Estruch is listed in securities documents as having been the CEO back in 2015.

Scholar with a history of making up author names has a 1985 paper corrected

A scholar who famously fabricated a meeting between Charles Dickens and Fyodor Dostoevsky used a bogus name to publish a 1985 paper in the journal History – and it was far from the first time.

Arnold Harvey, also known as AD Harvey, apparently created a small (precisely how small is unclear) community of scholars, including Stephanie Harvey, Graham Headley, Trevor McGovern, John Schellenberger, Leo Bellingham, Michael Lindsay and Ludovico Parra, as well as the Latvian poet Janis Blodnieks.

In a ruse outlined in this 2013 article for the Times Literary Supplement by Eric Naiman, of UC Berkeley, this fictitious klatch would critique each other’s papers. (Take note, peer review rings of the 2010s.)

As The Guardian wrote in a 2013 profile of Harvey that’s well worth a read:

Student of yoga tourism won’t get PhD as he earns five retractions

For Pramod Sharma, the study of yoga tourism has proven to be a downward-facing dog.

Last year, the Indian Institute of Technology (IIT) in Roorkee blocked Sharma – who posed as a legit yoga researcher but in reality stole other people’s work – from receiving his PhD after determining that his thesis was “plagiarized and lacks originality.” What’s more, according to the institution, a 2018 article by Sharma contained a “discrepancy in data…casting a doubt on the validity of the results.”

Journals have now retracted five papers by Sharma, although earlier concerns about the work didn’t reach his PhD committee in time to prevent him from defending his thesis in 2019.

We reviewed the IIT report on the Sharma case, and pulled out a couple of the choicest passages:
