‘Relieved’: BMJ retracts and replaces article on unexpected weight loss as a sign of cancer

Brian Nicholson

The British Medical Journal has retracted an article examining when unexpected weight loss could be a warning sign of cancer after the authors found an error in their work. The journal published an updated version of the analysis with different conclusions, which the authors think could influence patient care. 

The retracted paper, “Prioritising primary care patients with unexpected weight loss for cancer investigation: diagnostic accuracy study,” appeared Aug. 13, 2020. The researchers, led by Brian D. Nicholson, a general practitioner and associate professor in the Nuffield Department of Primary Care Health Sciences at the University of Oxford, England, used electronic health records data to look for people diagnosed with cancer within six months after a recording of unexpected weight loss. 

The authors were attempting to replicate their results in another dataset when they found “some differences in the study findings and study population that we could not easily explain,” Nicholson told Retraction Watch. He continued:

Expression of concern coming for paper some used to link COVID-19 vaccines to deaths

The journal BMJ Public Health is placing an expression of concern on a paper it said “gave rise to widespread misreporting and misunderstanding,” namely, “claims that it implies a direct causal link between COVID-19 vaccination and mortality.” 

The article, “Excess mortality across countries in the Western World since the COVID-19 pandemic: ‘Our World in Data’ estimates of January 2020 to December 2022,” appeared online June 3, and quickly attracted attention and criticism. The expression of concern is not yet live. 

In their conclusions, the authors wrote:

BMJ journal retracts, replaces study on chronic fatigue in children

A BMJ journal has retracted and replaced a paper on chronic fatigue in children after admitting that it misrepresented the nature of the research in the editing process. But the article has drawn scrutiny beyond merely the characterization of the analysis.

The paper, “Cognitive–behavioural therapy combined with music therapy for chronic fatigue following Epstein-Barr virus infection in adolescents: a feasibility study,” appeared in early April in BMJ Paediatrics Open, and was written by a group in Norway. The paper is technically not about chronic fatigue syndrome (CFS), but in the introduction the authors write:

If accompanied by other symptoms, such as exertion intolerance, chronic pain and cognitive impairments, the patient might fulfil one of the diagnostic criteria for chronic fatigue syndrome (CFS).

Authors claim clinical trial data came from one center. It came from three.

A BMJ journal has retracted a 2017 paper that made a false claim about the clinical trial in question. 

The Acupuncture in Medicine paper reported the results of a clinical trial about the impact of acupuncture and Chinese herbal medicine on stroke, gathered from one center. However, in November, the editors of the journal discovered that the authors had completed the trial at three centers, and had already published the data in Scientific Reports in 2016. The authors say the duplication and misrepresentation of the data stemmed from “confusion and misunderstanding.” Continue reading Authors claim clinical trial data came from one center.

BMJ journal pulls case report after UK tabloids publish graphic photos

A BMJ journal has retracted a medical case report about a couple in the United Kingdom who were infected by parasitic worms while on a Caribbean cruise.

The paper in BMJ Case Reports included graphic photos of the patients’ buttocks, the site of the infection, which were republished within a week by UK tabloids.

Specifics about when and why the journal retracted the paper remains unclear. BMJ Publishing Group, the journal, and the corresponding author have not responded to multiple requests for comment.

A UK-based lawyer, who has represented doctors in cases that touch on publishing and media law, told us there could be legal trouble. Martin Soames, of London firm Simons Muirhead & Burton, told Retraction Watch that UK laws governing patient confidentiality or protection of personal information could apply, raising problems for both the publisher and the doctors who wrote the paper. [See update at the end of the post, in which the editor says the paper was removed, and “does not consider that there are any issues of liability.”]  Continue reading BMJ journal pulls case report after UK tabloids publish graphic photos

“This is about saving kids’ lives:” Authors update pivotal car seat safety results

A BMJ journal has published an updated analysis of a 2007 paper that shaped current car seat safety recommendations, which reports less conclusive findings about the safest way to install the seat.

The updated analysis follows an expression of concern the journal Injury Prevention added to the paper in June 2017, after the authors and an outside expert could not replicate the results.

The 2007 paper made a big claim: Children ages one to two years old are five times more likely to sustain serious injuries in a crash when restrained in a forward-facing car seat than a rear-facing seat.

Benjamin Hoffman, a professor of pediatrics at Oregon Health & Science University in Portland who was not involved in the 2007 research, told us: Continue reading “This is about saving kids’ lives:” Authors update pivotal car seat safety results

Bone researcher is up to 17 retractions

A bone researcher has lost three more papers for scientific misconduct.

The new retractions bring Yoshihiro Sato’s total to 17 and put him on our Leaderboard.

According to the retraction notices, Sato asked the Journal of Neurology, Neurosurgery, and Psychiatry to retract three of his papers “due to scientific misconduct.” In the letter, Sato—who is corresponding author on all three papers—explained he included co-authors without their consent and that none of the other authors listed worked on the study or article.

In May, the editors issued expressions of concern while they investigated (1, 2, 3), and last month, the journal retracted the three articles.

Here’s the retraction notice for “Amelioration of osteopenia and hypovitaminosis D by 1alpha-hydroxyvitamin D3 in elderly patients with Parkinson’s disease:” Continue reading Bone researcher is up to 17 retractions

“Right to be forgotten” takes down BMJ’s 15-year-old film review

A subject in a documentary film about the psychology of religious ideation has pushed the BMJ to take down its review of the film, based on a complaint citing a European internet privacy rule.

On July 3, BMJ posted a retraction notice for an article that barely said anything:

This article has been retracted by the journal following a complaint.

The 2002 article is a review of a documentary film entitled “Those Who Are Jesus,” directed by Steven Eastwood, a British filmmaker. The review has been removed from the BMJ site, as well as PubMed.   

BMJ told Retraction Watch that it took down the film review in response to a European citizen exercising his or her “right to be forgotten,” an internet privacy idea that, according to the European Union, ensures:

BMJ journal yanks paper on cancer screening in India for fear of legal action

BMJ Global Health has pulled a paper that criticized U.S. research of the effects of cervical cancer screening in India over defamation concerns.

That’s not what the notice on the paper says, however — at the moment, it just reads:

This article has been withdrawn.

However, forwarded email correspondence between the first author and an associate publisher reveals the journal published the paper and planned a press release, then realized it should be reviewed by a legal adviser. When first author Eric J. Suba at Kaiser Permanente San Francisco Medical Center inquired about the status of the paper and any potential press release, he was told the journal could no longer publish it, out of concern they would be taken to court.

Suba told us that, when he learned the paper would be pulled:

Spam me once, shame on you. (Academic) spam me 3000 times…?

Every year, academics get thousands of spam emails inviting them to submit manuscripts or attend conferences — but don’t bother asking to “unsubscribe” for Christmas.

Spoiler alert, for those of you planning to read the rest of this post: It doesn’t make much of a difference.

That’s according to the conclusions of a study published in one of our favorite issues of the BMJ  — the Christmas issue. After a group of five self-described “intrepid academics” tried to unsubscribe from the 300+ spam invitations they received on average each month, the volume decreased by only 19% after one year.

Not surprisingly, many emails — approximately 1 in 6 — were duplicates (aka “reheated spam”), and the vast majority (83%) had little relevance to the researchers’ interests.

Study author Andrew Grey at the University of Auckland told us that since it’s the BMJ Christmas issue, they wanted to have a bit of fun. But it’s not an all-together light topic, he noted: Continue reading Spam me once, shame on you. (Academic) spam me 3000 times…?
