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 article, “SARS-CoV-2 Spike Impairs DNA Damage Repair and Inhibits V(D)J Recombination In Vitro,” was written by a pair of scientists at institutions in Sweden and published in MDPI’s Viruses (as Vincent Racaniello of TWiV would say, the kind that make you sick).

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. 

According to the journal: 

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:
