That study reporting worrisome levels of zinc in tuna? It’s being retracted

Recently, a rash of news outlets posted concerns that canned tuna and other products may contain potentially dangerous levels of zinc. They were all wrong.

News outlets such as The Daily Mail and The Sun reported findings from a recent study, which showed that canned foods such as tuna may contain 100 times the daily limit of zinc — raising concerns about how such huge doses of the mineral could be causing digestion problems. The last author of the study told Retraction Watch the paper is going to be retracted, because the authors made a fundamental error calculating the amount of zinc present in canned foods.

Last week, the UK’s biggest health website NHS Choices posted a critique of the paper, in which they recalculated the levels of zinc present in canned foods:

Political science has a #metoo moment

Many political scientists are up in arms over an editor’s decision to use his journal as a platform to defend himself from allegations of sexual harassment.

The editor, William Jacoby of Michigan State University, has since removed a statement denying the allegations from the American Journal of Political Science (AJPS), and posted an apology. Midwest Political Science Association (MPSA), which publishes the journal, has announced it’s asked Jacoby to “suspend all editorial operations until the council can take formal action later this week.”

Nutrition paper claims intervention cuts child obesity. Experts disagree.

Does incorporating gardens and their harvest into school-based nutrition programs help children get healthier? A 2017 paper claims it does, but a group of outside experts disagrees — strongly.

The 2017 paper reported that adding gardens to schools and teaching kids how to cook the harvest, among other elements, helped kids learn about nutrition — and even improved their body mass index, a measure of body weight.

However, soon after the paper appeared, a group of outside experts told the journal the data reported by the paper didn’t support its conclusions — namely, the authors hadn’t shown that the intervention had any effect. The authors performed an inappropriate analysis of the data, the critics claimed, and the paper needed to be either corrected or retracted outright.

But the Journal of Nutrition Education and Behavior has not amended the paper in any way. Instead, last month, it published the outside experts’ criticism of the paper, including their explicit calls to either correct or retract it, along with the authors’ response to the critics.

David Allison, the last author on the critical letter and the dean of the school of public health at Indiana University Bloomington, said he was surprised to see the journal chose to publish his critical letter, but not alter the paper itself:

“Youth Guru” loses turkey-neck paper that overlapped with book chapter

Ronald Moy

A prominent cosmetic surgeon and his daughter have lost a 2017 paper on treating men with excessive neck flab — otherwise known as “turkey neck” — because much of the work appears to have duplicated a book chapter he co-authored about the topic.

The first author of the retracted article is Ronald L. Moy, a plastic surgeon to the stars in Beverly Hills, Calif., and a past president of both the American Academy of Dermatology and the American Society of Dermatology. In a 2012 article about area plastic surgeons, LA Confidential Magazine dubbed Moy the “youth guru” and a local leader in the use of “new research and a comprehensive approach to restore a youthful complexion—no cutting required.”

His co-author was his daughter, Lauren Moy, who appears to be working with him in his Rodeo Drive dermatology practice.

Don’t like a paper, but don’t want to retract it? Just issue an “editorial statement”

Last April, the American Journal of Epidemiology and the American Journal of Public Health published a rare joint editorial statement. It concerned a pair of papers on the topic of mortality and obesity. Several complaints had prompted the journals to investigate. Their assessment: These papers contained inaccurate results.

The statement was not a retraction—it was a compromise the editors came up with that would set the academic record straight, while not tainting the authors’ publication record, given that they had (in the editors’ opinion) made honest mistakes. It was an unusual solution to a not-uncommon problem (criticisms of a paper), in which the editors tried to balance their duty to the scientific record against its potential impact on the authors. And it left few people happy — including researchers in the field, who are left unsure about the validity of the results.

Roland Sturm, an economist at Pardee RAND Graduate School who was not a co-author on the papers, told Retraction Watch:

A retraction gets retracted

Last year, an emergency medicine journal retracted a letter to the editor because it didn’t include the author’s potential conflict of interest. Now, it’s had a change of heart.

Earlier this month, the Canadian Journal of Emergency Medicine withdrew the retraction after determining the author, Guy Weinberg, had, in fact, provided information about his potential conflict  with his initial submission. Continue reading A retraction gets retracted

Caught Our Notice: Make love, not fake reviews — semen papers retracted

Titles: 

1) Study of enzyme activities and protein content of beluga (Huso huso) semen before and after cryopreservation

2) Determination of some blood and seminal plasma ions in the beluga, Huso huso (Linnaeus, 1758)

3) Effects of multiple collections on spermatozoa quality of Persian sturgeon, Acipenser persicus: Motility, density and seminal plasma composition

What Caught Our Attention: We won’t lie — any retractions of papers about fish semen (OK, any kind of semen) will make us stop and look. In this case, the journal retracted three papers submitted by the same researcher over concerns of fake review. In the end, the journal was concerned the papers were okayed by reviewers who weren’t “suitably qualified” to review the papers about the content and quality of semen from different fish species. (In fairness, we imagine the pool of qualified reviewers is relatively small.)

Authors retract heart disease paper for “nonscientific reason”

Researchers have retracted a 2018 paper about the genetic underpinnings of heart disease from the FASEB Journal — and it’s not entirely clear why.

The paywalled retraction notice simply cites a “nonscientific reason.” Cody Mooneyhan, the director of publications at the journal, declined to provide further details, and the authors have provided different accounts of what happened: The paper’s corresponding author, John Yu, told Retraction Watch that he requested the retraction because the first author, Chia‐Ti Tsai, refused to sign the journal’s copyright agreement. Tsai, a professor in the Department of Internal Medicine at National Taiwan University in Taipei, told us he was “not notified before the paper was submitted.” Continue reading Authors retract heart disease paper for “nonscientific reason”

Caught Our Notice: 54 problems in three scientific images equals one expression of concern

Title: Effects of microRNA-223 on morphine analgesic tolerance by targeting NLRP3 in a rat model of neuropathic pain

What Caught Our Attention: Usually, an Expression of Concern (EOC) offers general language about “concerns regarding the validity of the data” or “concerns regarding the integrity of the study.” Here the language is anything but, saying that 54 Western blot bands within three figures have problems such as “visible pasted joints,” “square border,” and numerous “appear to be the same band.”  According to the notice, the authors have not responded to requests for the original blots, so the editors are allowing the article to remain intact, choosing instead “to alert readers to these issues and allow them to arrive at their own conclusions regarding the figures.” Continue reading Caught Our Notice: 54 problems in three scientific images equals one expression of concern

Authors retract, replace highly cited paper on ADHD in kids

Researchers have retracted and replaced a 2014 paper in JAMA Psychiatry, exploring a new way to classify attention deficit hyperactivity disorder (ADHD) in children, after discovering errors in the data.

Some experts have criticized the current diagnostic criteria for ADHD—noting, in some cases, it could inflate the rate of diagnosis. Sarah L. Karalunas, the paper’s corresponding author, told Retraction Watch that the aim of the study was to look beyond current criteria and “demonstrate an approach that could be used to better delineate the boundaries of ADHD and other psychiatric diagnostic categories.”   Continue reading Authors retract, replace highly cited paper on ADHD in kids
