A gastroenterology journal has issued expressions of concern for forty articles about a probiotic formulation that has been at the center of a long-running legal saga in the United States and Europe.
The articles appeared in the Journal of Crohn’s and Colitis, the official journal of the European Crohn’s and Colitis Organisation (ECCO) and date back to 2007. All mention a proprietary formulation of probiotics – and therein lies the tale.
A group of heart researchers in China now have four expressions of concern, along with a retraction, for questions about the reliability of their data.
The latest expressions of concern for the team, led by Bu Lang Gao, of Shijiazhuang First Hospital of Hebei Medical University, involves a 2019 paper in Springer Nature’s Scientific Reports titled “Asymmetrical middle cerebral artery bifurcations are more vulnerable to aneurysm formation.”
Here’s the notice for the article, which has been cited 4 times, according to Clarivate Analytics’ Web of Science:
A PLOS journal has issued an expression of concern for a 2018 paper which claimed that ivermectin could be useful as a way to control dengue fever.
In fact, the reason the journal re-examined the article was because the hype about the use of ivermectin for Covid-19 led at least one skeptic to take a closer look at the study – and he didn’t like what he saw.
The article, “Antivirus effectiveness of ivermectin on dengue virus type 2 in Aedes albopictus,” was written by a group in China led by Tie-Long Xu, of the National Institute of Parasitic Diseases at the Chinese Center for Disease Control and Prevention. According to the study, which appeared on PLOS Neglected Tropical Diseases:
A virology journal has issued an expression of concern about a paper claiming that the SARS-CoV-2 virus can damage DNA after one member of the research team raised reservations about the reported findings.
The paper has received a fair amount of attention – particularly among vaccine skeptics who, as critics noted, used the article to buttress their claims that Covid vaccines are unsafe – generating enough buzz on social media and in the news to make it into the top 5% of all articles tracked by Altmetric. TWiV even devoted part of an episode of the show to the findings.
A journal has slapped an expression of concern on a 2021 paper reporting on the utility of self-administered “battlefield” acupuncture in soldiers, citing readers who said the FDA has not approved the devices for that use – a point the authors, who object to the move, dismissed as irrelevant and misleading.
The study, which appeared in Medical Acupuncture, looked at the experiences of a dozen veterans at an Ohio VA hospital who’d purportedly self-administered acupuncture to treat chronic pain. According to this 2010 article from the U.S. military:
The Journal of Neuroscience has slapped expressions of concern on a pair of papers linked to the maker of a controversial drug to treat Alzheimer’s disease.
As we and others have reported, Cassava Sciences has been under intense scrutiny lately. In August, the law firm Labaton Sucharow – who is representing Cassava short sellers – submitted a “citizen’s petition” to the FDA regarding a regulatory filing from the company for its drug simulfilam and called on the agency to halt trials of the experimental medication because it had:
Ettore Majorana, after whom the “Majorana” particle is named By unknown author / Mondadori Collection, public domain
You might say that the third time is not the charm for a paper on some elusive fermions.
For the third time this year, a leading science journal has raised concerns about a paper on the “Majorana” particle, which, if it exists, would hold promise for building a quantum computer.
An Elsevier journal has issued an expression of concern for a paper it published earlier this year by a Dutch researcher who studies the neurobiology of sexuality.
A leading heart journal has issued an expression of concern for a meeting abstract it published earlier this year by a cardiac surgeon who sells dietary supplements of questionable utility.
The case is the second involving a recent meeting of the American Heart Association.
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.
But critics have accused Gundry of peddling worthless — if ultimately expensive — advice.
A pediatrics journal has issued an expression of concern for a 2007 paper by a group of Canadian researchers whose leader, Gideon Koren, resigned in 2015 under a cloud after concerns surfaced about the integrity of the data in hundreds of his published studies.
Koren, once a prominent pediatrician and pharmacologist at the University of Toronto’s Hospital for Sick Children, ran the institution’s Motherisk Drug Testing Laboratory, which conducted hair testing for perinatal exposure to drugs and alcohol. In 2015, an investigation prompted by The Toronto Star found serious problems with the tests, which had been used in “used in thousands of child protection cases and several criminal cases.”
Koren stepped down that year, and in 2019 relinquished his license to practice medicine in Ontario. Reporting by the Star prompted Koren’s institution to order a review of more than 400 of his published papers. To date, by our count, journals have retracted five of Koren’s papers, corrected four, and have now issued three expressions of concern.
