The editor in chief of the journal Food and Chemical Toxicology (FCT) has resigned with more than a year left of his term, according to an email announcing his move to colleagues. 

In the email, first reproduced in Steve Kirsch’s Substack newsletter, the editor, Jose L. Domingo, cited “deep discrepancies” with the journal’s direction under publisher Elsevier as the reason for his early resignation. He shared the email with us when we reached out for comment. 

Domingo, a professor of toxicology and environmental Health at the Universitat Rovira i Virgili in Spain, listed three main points of contention: an agreement for the journal to publish documents for the Research Institute for Fragrance Materials, which Domingo believed to be a “drag” on the journal’s impact factor; FCT’s recent designation as the official journal of the Chinese Society of Toxicology; and a February editorial he wrote requesting submissions “on the potential toxic effects of COVID-19 vaccines.” 

He wrote:

A journal editor is defending his decision to publish a new paper showing that ivermectin can prevent Covid-19, despite more than a dozen retractions of such papers from the literature.

The article, “Regular Use of Ivermectin as Prophylaxis for COVID-19 Led Up to a 92% Reduction in COVID-19 Mortality Rate in a Dose-Response Manner: Results of a Prospective Observational Study of a Strictly Controlled Population of 88,012 Subjects,” appeared in Cureus August 31. 

The authors included Pierre Kory, a critical care specialist better known as the leader of the   Front-Line Covid-19 Critical Care Alliance, based in Madison, Wis.  Kory has been an active promoter of the use of ivermectin and other questionable remedies for  Covid-19 – even testifying before Congress about his ideas – although his most high-profile paper on the topic was retracted last November.

In February, the editor-in-chief of Food and Chemical Toxicology published an editorial calling for “Papers on potential toxic effects of COVID-19 vaccines.” Following this call, in April 2022, the journal – no stranger to Retraction Watch readers –  published an article titled “Innate immune suppression by SARS-CoV-2 mRNA vaccinations: The role of G-quadruplexes, exosomes, and MicroRNAs.” 

At more than 16,000 words and more than 200 references, the article was submitted on February 9^th and accepted on April 8^th. It claims that “billions of lives are potentially at risk” with Covid-19 vaccines. 

Such an important statement should be supported by facts. But this is not at all the case. And yet the paper has been shared more than 45,000 times on social media, in ways that decrease trust in science and the COVID-19 vaccine, despite the robust evidence that it is both safe and efficient.

When a retracted paper is republished in a new journal, should it note the retraction?

A few readers have asked us that question as they forwarded a paper published in May in Environmental Research, an Elsevier title. The study, “Carbon dioxide rises beyond acceptable safety levels in children under nose and mouth covering: Results of an experimental measurement study in healthy children,” bore striking similarities to a paper by the same authors that was retracted from JAMA Pediatrics in July 2021. 

That retraction was the second for the paper’s first author, Harald Walach, who also lost an affiliation with a university in Poland. Walach tells us that he let the editor know about the JAMA Pediatrics retraction before he submitted the manuscript:

Researchers in Iran have lost a paper on Covid-19 infection in a two-month-old boy after the journal learned that they’d fabricated ethics approval for the article. 

It’s the 250th Covid-19 retraction by our count.

“Coronavirus disease 2019 in a 2-month-old male infant: a case report from Iran” appeared in December 2020 in Clinical and Experimental Pediatrics. The senior author of the paper was Sajjad Ahmadpour, of the Gastroenterology and Hepatology Diseases Research Center at Qom University of Medical Sciences.

According to the retraction notice (which doesn’t appear in the expected place but can be found here):

A journal has retracted a paper reporting the results of a clinical trial in which a drug cut COVID-19 hospitalization for men by 90%. 

The research group’s other work has attracted a lot of attention in Brazil – including praise from  president Jair Bolsonaro and criticism from research regulators – for their dramatic results. In a Twitter thread, one of the authors claimed, without evidence, that the journal “may have received bribery to persecute us and retract our study.”

The article, “Proxalutamide Reduces the Rate of Hospitalization for COVID-19 Male Outpatients: A Randomized Double-Blinded Placebo-Controlled Trial,” was published in Frontiers in Medicine last July and has been cited 15 times, according to Clarivate’s Web of Science. 

The study quickly attracted criticism, according to the retraction notice:

Days after a leading heart journal issued an expression of concern for a meeting abstract suggesting that vaccines against Covid-19 may cause cardiac damage, its publisher, the American Heart Association (AHA), says it is reviewing how it screens such submissions. 

As we reported late last month, “Mrna COVID Vaccines Dramatically Increase Endothelial Inflammatory Markers and ACS Risk as Measured by the PULS Cardiac Test: a Warning,” was presented at the AHA’s 2021 Scientific Sessions in mid-November and was published in Circulation. 

The author was Steven Gundry, a cardiac surgeon by training who now sells dietary supplements 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. (His critics say what Gundry peddles costs much more than it’s worth.)

After an outcry, Circulation flagged the published poster with the following notice:

The authors of a preprint on use of hydroxychloroquine — the controversial drug heavily promoted by, and now apparently taken by, President Trump, at least for a few more days — along with azithromycin for COVID-19 have withdrawn the paper.

The preprint, “Hydroxychloroquine plus azithromycin: a potential interest in reducing in-hospital morbidity due to COVID-19 pneumonia (HI-ZY-COVID)?” was posted to medRxiv on May 11 by authors at Hopital Raymond Poincare, and sometime yesterday replaced with this statement:
