Widely shared vitamin D-COVID-19 preprint removed from Lancet server

A preprint promoted by a member of the UK Parliament for claiming to show that vitamin D led to an “80% reduction in need for ICU and a 60% reduction in deaths” has been removed from a server used by The Lancet family of journals.

The preprint, “Calcifediol Treatment and COVID-19-Related Outcomes,” was posted to Preprints with The Lancet on January 22. On February 13, David Davis, a Conservative member of UK’s Parliament, tweeted:

Leading evidence-based group blames pandemic for 9-month delay pulling flawed cancer review

Last February, Richard Pollock was reading a review in the Cochrane Database of Systematic Reviews — a prominent resource for evidence-based medicine —  when he spotted an error. 

In the first figure, which compared the effectiveness of two different treatments for the most common form of liver cancer, a label was switched. The error made it seem like the “worse” treatment was better than the more effective option.

Pollock, a health economist, was concerned enough to send an email to Omar Abdel-Rahman, the corresponding author, on February 20th. Abdel-Rahman, an oncologist at the University of Alberta, wrote back the next day, saying he would review the comments with experts at Cochrane, “and if there is any typos in the publication, it will be corrected immediately.” Emails seen by Retraction Watch show that, when replying to this email, Abdel-Rahman copied one of Cochrane’s editors, Dimitrinka Nikolova.

Months passed. Pollock sent another email to Abdel-Rahman and two Cochrane editors — Nikolova and Christian Gluud — on June 15th. Then, on November 16th, the journal pulled the review with a brief notice:

Exercise science grad student at Australian university dismissed after he admitted faking data, says supervisor

A physiology journal has retracted a pair of papers from a group in Australia after learning that the flawed work was the subject of an institutional investigation.

The articles, both of which were published last year in The Journal of Strength and Conditioning Research, came from a group at the Murdoch Applied Sports Science Laboratory, part of Murdoch University. The first author on both papers was Liam J. Hughes, a PhD student at Murdoch who was terminated as a result of the misconduct.

JAMA journal retracts its first paper, on exercise and heart disease

The authors of a 2019 meta-analysis in a JAMA journal on exercise and heart disease have retracted the paper after discovering that a quarter of the studies they’d used in the analysis did not belong. 

The retraction is the first for the journal, which had published some 2,800 articles before having to pull one, Frederick P. Rivara, the editor in chief, told Retraction Watch. One in 2,800, we should note, is quite close to the 4 in 10,000 rate of retraction in the overall literature.

The study, from a group at the Universities of Manchester and Brighton, in the United Kingdom, was titled “Accelerometer- and pedometer-based physical activity interventions among adults with cardiometabolic conditions: a systematic review and meta-analysis,” and appeared in JAMA Network Open

The authors, led by Alexander Hodkinson, looked at 36 randomized clinical trials and found that:

Medical writer loses COVID-19-cancer paper for plagiarism

via CDC

An oncology journal has retracted a review article on the hypothetical link between Covid-19 and cancer after determining that the medical writer who authored the work hadn’t done all the writing herself. 

The paper, “Clinical sequelae of the novel coronavirus: does COVID-19 infection predispose patients to cancer?” appeared in Future Oncology in May and was written by Priya Hays, who at the time was a technical writer with Talis Biomedical Corp., in Menlo Park, Calif. Hays is currently with Abbott, according to her LinkedIn profile. She also has a company called Hays Documentation Specialists, which offers a variety of manuscript services, including academic writing and something called “unstructured authoring assistance.” 

As the retraction notice indicates, Hays appears to have had some authoring assistance of her own:

‘Misconduct on a grand and terrible scale’: Dental scientist up to 26 retractions

Jose Luis Calvo-Guirado

A dentistry researcher in Spain with a history of reusing and manipulating images has notched two more retractions, giving him 26. 

The new retractions move Jose´ Luis Calvo-Guirado, of Universidad Católica San Antonio de Murcia, into a tie for 24th place on the Retraction Watch leaderboard

Calvo-Guirado has in the past disputed the retractions of his research. And at least one of his co-authors, Georgios Romanos, of the State University of New York Stony Brook School of Dental Medicine, speculated that Calvo-Guirado was reusing images to limit the number of lab animals that would need to be sacrificed in his studies.

The latest retractions involve two papers in Annals of Anatomy, an Elsevier publication, including the 2018 article “A new procedure for processing extracted teeth for immediate grafting in post-extraction sockets. An experimental study in American Fox Hound dogs.” According to the notice, the paper contained manipulated images that were reused in subsequently retracted articles:

Elsevier looking into “very serious concerns” after student calls out journal for fleet of Star Trek articles, other issues

Hampton Gaddy

An undergraduate student in the United Kingdom has taken to task the editors of a purportedly scholarly journal for having published more than 100 papers by a Maltese researcher with a deep affinity for Star Trek.

In a Dec. 8, 2020, letter to the editors of Early Human Development (EHD), Hampton Gaddy, a BA student at the University of Oxford, accuses the journal of having published “a large number of unprofessional articles” by Victor Grech, of the University of Malta. 

Grech is a pediatric cardiologist, and, evidently a huge Star Trek fan. He’s also a prolific author, and seems to have turned EHD into something of a personal fanzine. As Gaddy notes in his letter, Grech has written at least 113 papers in EHD, an Elsevier title, 57 as sole author:

Authors of meta-analysis on heart disease retract it when they realize a NEJM reference had been retracted

Carl Heneghan

The authors of a meta-analysis on predicting cardiovascular disease have retracted the paper because it included a study that was retracted between the time they submitted their article and the date it was published. 

If only there were a repository of retracted articles that authors and editors could check to see if the references in the studies they publish are still reliable.

Wait, we have one of those!

Public health journal “seeking further expert advice” on January paper about COVID-19 PCR testing by high-profile virologist

After a petition from nearly two dozen people in Europe, the United States and Asia, a public health journal says it is investigating an article it published last January about a way to detect the virus that causes COVID-19. 

[Please see an update on this post.]

The paper, “Detection of 2019 novel coronavirus (2019-nCoV) by real-time RT-PCR,” appeared in Eurosurveillance. It was received on January 21 and accepted on January 22, a remarkably quick turnaround under normal circumstances, although not unheard of during the pandemic. It has been cited well over 800 times, according to Clarivate Analytics’ Web of Science.

The senior author of the work was Christian Drosten, of the Charité University Hospital in Berlin, who became something of a celebrity virologist — the Anthony Fauci of Germany — in the early days of the pandemic. As Science reported in late April, Drosten’s podcast, Coronavirus Update, became the most popular podcast in Germany, garnering more than 1 million downloads per episode.

Johns Hopkins student newspaper deletes, then retracts, article on faculty member’s presentation about COVID-19 deaths

A student newspaper at Johns Hopkins has retracted an article claiming that COVID-19 has had “relatively no effect on deaths in the United States.”

The article, “A closer look at U.S. deaths due to COVID-19” (link from the Wayback Machine) was published on November 22 and relied on a presentation by Genevieve Briand, assistant program director of the Applied Economics master’s degree program at Hopkins. 

From the article:
