Category: expression of concern

Mere days after tweets went viral pointing out  that the purported error bars in one figure of a paper were really just the capital letter T, the publisher has marked it with an expression of concern. [12/22/22: The paper has now been retracted; see an update on this post.]

And that’s not all that’s strange about the paper. 

The July 2022 article, “Monitoring of Sports Health Indicators Based on Wearable Nanobiosensors,” was published in a special issue of the journal Advances in Materials Science and Engineering, a Hindawi title. 

The article purports to show that using nanoparticles can better measure the biochemical fitness levels of elderly people than other methods.

The author of an article on unwanted pregnancies that has received an expression of concern for reasons that remain unclear says she has hired lawyers to defend herself against “defamation.”  

Priscilla K. Coleman, a professor of human development and family studies at Bowling Green State University in Ohio – whose controversial work on the link between abortion and mental health problems has come under scrutiny – told us that she plans “to actively pursue all options available including legal avenues to rectify the situation” after Frontiers in Social Health Psychology slapped the EoC on her 2022 article. 

The paper in question was titled “The Turnaway Study: A case of self-correction in science upended by political motivation and unvetted findings.” The Turnaway Study is an ongoing look by researchers at the University of California, San Francisco at the effects on women – including the physical, emotional, and economic toll – of carrying unwanted pregnancies. The main finding, according to its site, “is that receiving an abortion does not harm the health and wellbeing of women, but in fact, being denied an abortion results in worse financial, health and family outcomes.”

The abstract for Coleman’s review reads, in part:

A paper with scientific sleuth Elisabeth Bik as a co-author now has an expression of concern. It dated back to her time at the now-defunct startup uBiome and described research that the company used to develop a clinical test of bacteria living in the human gut – and that she raised concerns about some years ago.

The article, “16S rRNA gene sequencing and healthy reference ranges for 28 clinically relevant microbial taxa from the human gut microbiome,” was published in PLOS ONE in 2017 and has been cited 39 times, according to Clarivate’s Web of Science. 

The expression of concern detailed the journal’s investigation into allegations that some of the samples in the paper weren’t suitable for determining a healthy baseline of the human gut microbiome — being from infants, people who might have recently taken antibiotics, and pets — and the authors’ responses. 

It’s a long notice, but this paragraph sums up the concerns:

A journal has issued an expression of concern for a federally-funded paper on Alzheimer’s disease after a sleuth on PubPeer noted potentially duplicated figures in the article. 

We shouldn’t forget to mention, as the paper did, that one of the authors – a prominent scientist who happens also to be a co-editor in chief of the journal – has financial ties to a company with interest in the work. That author said the fault lies with the corresponding author.   

Oh, what a tangled web we weave, it seems, when it comes to neurofibrillary tangles. And we’ve seen at least one other case of a paper failing to disclose conflicts of interest in a paper he’d published in his own journal. (This is a subject that has been taken up elsewhere.)

The article in this case, “Human Umbilical Cord Blood-Derived Monocytes Improve Cognitive Deficits and Reduce Amyloid-β Pathology in PSAPP Mice,” appeared in Cell Transplantation, a SAGE title, in November 2015.

An Elsevier journal has issued a rather remarkable expression of concern for a 2021 paper on rabbit husbandry after learning that the lead author misrepresented the authorship of the article – and possibly more. 

The paper, “Supplementing rabbit diets with butylated hydroxyanisole affects oxidative stress, growth performance, and meat quality,” appeared in animal and ostensibly came from a group in Egypt and Saudi Arabia led by Tharwat Imbabi.

But as the journal explains, the article wasn’t the first rabbit rodeo for Imbabi, of the department of animal production at Benha University. According to the notice, the researcher had failed repeatedly to publish his manuscript in other journals, so he turned to “third parties” for help. 

Those contributors did the bulk of the work  – but wanted none of the credit. Meanwhile, Imbabi appears to have found other authors willing to join the list. 

We’ll let the expression of concern tell the rest:

A psychiatry journal has issued expressions of concern for four papers by a group of researchers in Russia after questions surfaced about the integrity of the data. 

The first author on all of the papers was Ilya D. Ionov, of the Centre On Theoretical Problems in Physical and Chemical Pharmacology, part of the Russian Academy of Sciences in Moscow. The co-authors are affiliated with Timpharm LTD, a drug company without much in the way of an online presence.

The papers appeared in Psychopharmacology, a Springer Nature title. 

Here’s the notice for “Anticataleptic activity of nicotine in rats: involvement of the lateral entorhinal cortex,” which Psychopharmacology published in 2021:
