PLOS ONE issues expression of concern for study of dog food and heart problems for failure to disclose conflicts of interest, other issues

via Southern California Golden Retriever Rescue

A group of veterinary researchers at the University of California, Davis, has received an expression of concern for their May 2020 study on heart disease in dogs, for failing to adequately disclose conflicts of interest and for other aspects of the article.

The paper, “Development of plasma and whole blood taurine reference ranges and identification of dietary features associated with taurine deficiency and dilated cardiomyopathy in golden retrievers: A prospective, observational study,” appeared in PLOS ONE. The authors, from the lab of Joshua A. Stern, looked at the effects on the animals of “non-traditional” diets — those high in legumes but low in grains, which contain taurine, a key amino acid. Golden retrievers are known to be particularly vulnerable to cardiac problems associated with a lack of taurine. The FDA has been investigating the connection.

According to the authors:

PubPeer comments prompt Science expression of concern

Science has issued an expression of concern for a paper it published earlier this summer after readers pointed out suspect images in the work.

The July 10 article, titled “Proton transport enabled by a field-induced metallic state in a semiconductor hetero-structure,” came from a group in China and the United Kingdom. The corresponding authors were Bin Zhu and Huaibing Song, of China University of Geosciences in Wuhan. Zhu also is affiliated with the Southeast University School of Energy and Environment in Nanjing.

Shortly after publication, data-sleuth Elisabeth Bik posted on PubPeer that she’d been alerted by a reader to potential problems with two of the figures in the paper:

Apparent duplication from anesthesiology journal puts heart paper into intensive care

A heart journal has issued an expression of concern about a 2017 paper which looks suspiciously like a 2016 article by some of the same researchers that appeared in an anesthesiology publication.

The 2017 paper, “Efficacy of prophylactic dexmedetomidine in preventing postoperative junctional ectopic tachycardia after pediatric cardiac surgery,” was written by a group led by Doaa Mohamed El Amrousy, of Tanta University Hospital in Egypt.

Several months earlier, El Amrousy and two of his co-authors, Nagat S. El-Shmaa and Wael El Feky, published a similar article in the Annals of Cardiac Anesthesia, titled “The efficacy of pre-emptive dexmedetomidine versus amiodarone in preventing postoperative junctional ectopic tachycardia in pediatric cardiac surgery.”

How similar? Apparently too much.

Paper earns expression of concern after author blames COVID-19 restrictions for not being able to find raw data

The pandemic ate our data.

A group of researchers in India whose findings in a 2015 paper evidently looked too good to be true have received an expression of concern because they claim Covid-19 restrictions have made it impossible to recover their raw data.

The article, “Possible role of P-glycoprotein in the neuroprotective mechanism of berberine in intracerebroventricular streptozotocin-induced cognitive dysfunction,” appeared in Psychopharmacology, a Springer Nature journal. The authors, led by Anil Kumar, were affiliated with the University Institute of Pharmaceutical Sciences at Panjab University in Chandigarh.

NEJM, Lancet place expressions of concern on controversial studies of drugs for COVID-19

[See update on this story.]

As controversy swirls around two papers that used data from Surgisphere, the New England Journal of Medicine and The Lancet have placed expression of concerns on the relevant papers.

Here’s the NEJM expression of concern:

A paper plagiarizes an article retracted for plagiarism and other sins — but it isn’t being retracted.

We make a point of never calling for a particular paper’s retraction, nor ever weighing in on whether a journal should have made that move. That would be, we often say, like a financial reporter recommending stocks. But a recent expression of concern is sorely testing our resolve on the matter.

The expression of concern is for a 2014 article, “shRNA-mediated silencing of ZFX attenuated the proliferation of breast cancer cells,” which appeared in Cancer Chemotherapy and Pharmacology, a Springer title, and was led by a team from Zhejiang Cancer Hospital in Hangzhou.

Here’s the notice:

Journal expresses concern about possible animal abuse in trauma paper

A journal has issued an expression of concern over a 2018 paper which involved strapping 21 anesthetized minipigs to sleds and running them into a wall at speeds of up to 25 miles per hour.

The study, “Experimental study of thoracoabdominal injuries suffered from caudocephalad impacts using pigs,” came from the Third Military Medical University in Chongqing, China, and was funded by the People’s Liberation Army.

About those impacts. The purpose of the study, according to the abstract, was this:

“Based on the literature, we have no reason not to believe to the authors.”

If you’re a fan of the post hoc fallacy, this post is for you. If not, we hope you’ll bear with us anyway.

In June, we reported on an expression of concern in the Journal of Cell Science for a 2006 paper “several bands…in Fig. 5 look very similar.” At the time, we noted that while the expression of concern claimed that the Istituto Superiore di Sanità, the authors’ institution, “does not have a suitable body to investigate this matter,” it in fact does.

After hearing that from us, Sharon Ahmad, the journal’s managing editor, approached Carlos Petrini, the director of bioethics at the ISS, who proceeded to investigate the work. Petrini has now sent us the summary of that investigation, which we’ve made available here.

Leech paper nets expression of concern

An article claiming to uproot the evolutionary tree of leeches has received an expression of concern after a reader notified the journal about potential problems with the data.

The article, “Phylogenomic analysis of a putative missing link sparks reinterpretation of leech evolution,” appeared online in Genome Biology and Evolution, an Oxford University Press title, on June 19 of this year. According to the authors — an international team that includes researchers at the National Museum of Natural History, the North Carolina Museum of Natural Sciences, Florida State University and University of Gothenburg in Sweden — their results:

Journals flag two papers by prominent researcher — who is also on trial for domestic abuse

Adeel Safdar was once a rising star in the field of kinesiology. After completing his doctorate degree at McMaster University in Canada, working with one of the titans of his field, Safdar took a postdoc at Harvard, then accepted a newly created chair position at another university in Ontario.

That all came crashing down last year, when Safdar went on trial in Canada, accused of horrifically abusing his wife. Over the course of the trial, allegations arose about his research, prompting two journals to flag papers he co-authored with his former mentor, Mark Tarnopolsky.

Tarnopolsky — author of more than 400 papers, which have collectively been cited more than 17,000 times, according to Clarivate Analytics’ Web of Science — told Retraction Watch:
