Calling exercise data “atypical, improbable, and to put it bluntly, pretty weird,” sleuths call for seven retractions

Sleuth James Steele

A group of data sleuths is calling for the retraction of seven articles by an exercise physiologist in Brazil whose data they believe to be “highly unlikely” to have occurred experimentally.

In a preprint posted to the server SportRxiv, the group — led by Andrew Vigotsky, a biomedical engineer at Northwestern University — details their concerns about the work of Matheus Barbalho, a PhD student at the Centro de Ciências Biológicas e da Saúde, part of the  Universidade da Amazônia, in Belém. Barbalho’s mentor is Paulo Gentil.  

In addition to the preprint, titled “Improbable data patterns in the work of Barbalho et al,” Greg Nuckols, one of the coauthors, has posted a lengthy “explainer” about the analysis. 

The Brazilian group already has one retraction, for a study in the International Journal of Sports Physiology and Performance titled “Evidence of a ceiling effect for training volume in muscle hypertrophy and strength in trained men—less is more?” According to the notice:

“[H]ow gullible reviewers and editors…can be”: An excerpt from Science Fictions

We’re pleased to present an excerpt from Stuart Ritchie’s new book, Science Fictions: How Fraud, Bias, Negligence, and Hype Undermine the Search for Truth.

One of the best-known, and most absurd, scientific fraud cases of the twentieth century also concerned transplants – in this case, skin grafts. While working at the prestigious Sloan-Kettering Cancer Institute in New York City in 1974, the dermatologist William Summerlin presaged Paolo Macchiarini—an Italian surgeon who in 2008 published a (fraudulent) blockbuster paper in the top medical journal the Lancet on his successful transplant of a trachea—by claiming to have solved the transplant-rejection problem that Macchiarini encountered. Using a disarmingly straightforward new technique in which the donor skin was incubated and marinated in special nutrients prior to the operation, Summerlin had apparently
grafted a section of the skin of a black mouse onto a white one, with no immune rejection. Except he hadn’t. On the way to show the head of his lab his exciting new findings, he’d coloured in a patch of the white mouse’s fur with a black felt-tip pen, a deception later revealed by a lab technician who, smelling a rat (or perhaps, in this case, a mouse), proceeded to use alcohol to rub off the ink. There never were any successful grafts on the mice, and Summerlin was quickly fired.

A physics paper claimed the Koran had predicted the discovery of the Higgs Boson. Now it has an expression of concern.

A paper on how the Koran anticipated the discovery of the Higgs Boson — aka the “God particle” — has been hit with an expression of concern.

The article, “God particles in the perspective of The AlQuran Surah Yunus: 61 and modern science,” appeared in the Journal of Physics: Conference Series, which in 2017 published submissions to the 2016 International Conference on Science and Applied Science (Engineering and Educational Science), held in Indonesia. It was authored by Sri Jumini, of the Physics Department Program of Sains AlQuran University in Java.

Being neither particle physicists nor scholars of world religions, we’re not well-equipped to summarize Jumini’s theory, so here’s how he describes the work in the abstract:

French hydroxychloroquine study has “major methodological shortcomings” and is “fully irresponsible,” says review, but is not being retracted

Frits Rosendaal

A March 2020 paper that set off months of angry debates about whether hydroxychloroquine is effective in treating COVID-19 has “gross methodological shortcomings” that “do not justify the far-reaching conclusions about the efficacy of hydroxychloroquine in Covid-19,” according to a review commissioned by the journal that published the original work.

The comments, by Frits Rosendaal, of Leiden University Medical Center in the Netherlands, came as part of a review commissioned by International Society of Antimicrobial Chemotherapy (ISAC), which publishes the journal along with Elsiever. ISAC had issued a statement about the paper in April, saying it “does not meet the [International Society of Antimicrobial Chemotherapy’s] expected standard.”

The study, Rosendaal writes,

Fowl play? Poultry researcher has two more papers retracted for “grave mistakes”

The journal Poultry Science has retracted two papers for authorship issues. 

The first author on both articles was Sajid Umar, of the Arid Agriculture University, in Rawalpindi, Pakistan, who now has lost at least four papers for similar reasons. 

One article, from 2016, was titled “Synergistic effects of thymoquinone and curcumin on immune response and anti-viral activity against avian influenza virus (H9N2) in turkeys.” According to the retraction notice:

Painfully awkward: Duplicate anesthesiology study retracted

A study that compared drugs used to reverse the effects of relaxants for surgery has been retracted because the majority of the results were already published.

The study, “Comparison of sugammadex and pyridostigmine bromide for reversal of rocuronium-induced neuromuscular blockade in short-term pediatric surgery,” appeared in the journal Medicine in February 2020.

The work found that the drug sugammadex worked faster than pyridostigmine in children undergoing surgery, and doesn’t appear to have anything wrong with it. But a study with the same authors and same name (barring a single uncapitalized letter) had already been published in the journal Anesthesia and Pain Medicine on July 31, 2019.

“Consistently unsurprised”: Nigerian vaccine study with no Nigerian authors retracted

Last month, PLOS ONE published a paper reporting on a trial to improve the uptake of the measles vaccine in Nigeria. The researchers were affiliated with IDinsight, a San Francisco-based “global advisory, data analytics, and research organization that helps development leaders maximize their social impact.”

San Francisco is about 7,800 miles from Lagos, and the list of authors — Sam Brownstone, Alison Connor and Daniel Stein, a former economist at the World Bank — seemed suspiciously devoid of Nigerian names.  

That omission was even more strange given the title of the article: “Improving measles vaccine uptake rates in Nigeria: An RCT evaluating the impact of incentive sizes and reminder calls on vaccine uptake.” Almost immediately after publication, Ejemai Eboreime, a physician and public health worker, pointed out on Twitter the implausibility of the implied claim that no local scientists were involved in a randomized controlled trial covering nine clinics throughout the country — which he alleged also was a violation of local research ethics provisions.

A mystery: How did this team plagiarize an unpublished paper?

A study on a wireless communication algorithm was retracted for being an exact duplicate of a paper submitted to a separate journal last year — but the authors were different and it’s unclear how they got hold of it.

The retracted study, “Energy-aware resource management for uplink non-orthogonal multiple access: Multi-agent deep reinforcement learning” was published in the Elsevier journal Future Generation Computer Systems. Neither the author of the original work who we were able to reach, nor either journal involved, say they know how the unpublished manuscript got into another group’s hands.

Here’s the (complicated) timeline:

French university rescinds researcher’s PhD after misconduct finding

A university in France has stripped a researcher of her doctoral degree after she was found to have committed misconduct in at least two studies of yeast. 

As we reported in May, Marjorie Petitjean, who received her PhD from the National Institute of Applied Sciences at the University of Toulouse, was accused of having fabricated and manipulated data while in the lab of Jean-Luc Parrou — who described her output as “a complete work of fiction.”

Petitjean left Parrou’s lab for a post-doc in Scotland, where, he said, she continued her bad habits:
