Caught Our Notice: Brian Wansink issues correction that’s longer than original paper

without comments

Title: Attractive names sustain increased vegetable intake in schools

What Caught Our Attention: One thing can be said for the corrections for Brian Wansink‘s papers — they aren’t short.  After James Heathers outlined some of his concerns about the highly cited study back in March, 2017, the journal has issued a correction, and it’s longer (1636 words) than the original, highly cited paper (1401 words). Some of the changes include explaining the children studied were preschoolers (3-5 years old), not preteens (8-11), as originally claimed. (It may be hard to imagine how the authors could make such a mistake, but they did it once before, in another retracted paper.) Even with all those words explaining the correction — we’re only including an excerpt of the entire notice below — some concerns still remain: Read the rest of this entry »

Study that said hate cuts 12 years off gay lives fails to replicate

with 9 comments

A highly cited paper has received a major correction as a result of the ongoing battle over attitudes towards gay people, when a prominent — and polarizing — critic showed it could not be replicated.  

In December 2017, researchers led by Mark Hatzenbuehler of Columbia University corrected the paper, originally published in Social Science & Medicine in February 2014, which showed that gay people who live in areas where people were highly prejudiced against them had a significantly shorter life expectancy. The corrigendum came more than a year after a researcher who has testified against same-sex marriage was unable to replicate the original study.

“Structural stigma and all-cause mortality in sexual minority populations,” has been cited 102 times, according to Clarivate Analytics’ Web of Science, and attracted media coverage when it was published, from outlets such as Reuters and U.S. News & World Report.

Macchiarini, 3 co-authors found guilty of misconduct in 2015 paper

with one comment

The Karolinska Institutet in Sweden has declared that once-lauded surgeon Paolo Macchiarini and three co-authors committed misconduct in a 2015 paper.

The decision by KI’s vice chancellor will be followed by a request to retract the paper, published by the journal Respiration.

In the paper, the researchers described the case of a man with an acute lung disorder, in which he received an experimental treatment involving the use of his own blood-derived cells and the drug erythropoietin, which stimulates the production of red blood cells. The patient “demonstrated an immediate, albeit temporary, clinical improvement,” according to the authors. However, he ultimately died of multisystem organ failure.

For the second time, researchers retract — then republish — a vaccine paper

with 3 comments

Two researchers with a troubled publication history about vaccine safety have withdrawn their third paper.

Along with several other co-authors, Christopher Shaw, of the University of British Columbia, and Lucija Tomljenovic, of the Neural Dynamics Research Group, recently withdrew a 2017 paper about a controversy over a tetanus vaccination program in Kenya.  

The paper has been republished in the same journal, adding another chapter to Shaw and Tomljenovic’s confusing record of publishing and withdrawing papers. The journal did not respond to our request for comment, but Shaw told Retraction Watch:

Second paper tied to drug scandal in Norway ski team retracted

without comments

Researchers in Norway have retracted a second high-profile exercise paper — again after running afoul of an ethical approval committee.

As part of the 2016 study, the researchers gave athletes asthma medication to measure its effect on signals from the nervous system to the lungs; although the drug appeared to have no detectable effect on the nervous system signals, 45 minutes after getting the drug, athletes (including those without asthma) showed an average slight increase in one measure of lung function.

Annette Birkeland, of The Norwegian National Research Ethics Committees (FEK), told us:

“The most terrible experience of my life:” Authorship dispute leads to lawsuit

without comments

A journal has retracted a 2014 paper because of an authorship dispute that became the subject of litigation.

Last year, the Allegheny Health Network in Pittsburgh requested the paper be retracted to resolve the dispute. The Journal of Applied Biomaterials & Functional Materials retracted the paper in October.

According to the retraction notice, the principal investigator of a clinical trial on which some of the study is based was not included as a co-author, and claimed he had not “validated the accuracy of the data.”

The notice does not mention a lawsuit, but a letter from the authors’ research institution does.

Journal retracts letter for missing disclosure author says he tried to submit

without comments

An emergency medicine journal has retracted a letter to the editor, saying it didn’t include the author’s relevant commercial interest—which the author says he tried to disclose when he submitted the paper.

The author, Guy Weinberg, told Retraction Watch he had noted his conflict of interest when he submitted the letter last March, but said he did not use the journal’s disclosure form. He added that his primary concern is that the editors didn’t reach out to him to discuss the issue prior to retracting the letter.

Here’s the retraction notice for “Assessing Efficacy of Lipid in Unstable, non-LAST Overdose Patients,” published on Sept. 18 in the Canadian Journal of Emergency Medicine: Read the rest of this entry »

CrossFit asks court to unmask peer reviewers of retracted study

with 9 comments

Another front has opened up in the legal battle between the CrossFit exercise brand and a competitor, spurred by a now-retracted paper about the risk of injury from the workout program. Soon, a judge will decide whether CrossFit is entitled to learn the names of the study’s peer reviewers.

CrossFit has tried and failed to identify them before. If they’re successful now, it could help establish a new way to legally breach reviewer confidentiality; two outside lawyers we consulted said they’d never before seen a court order a journal to reveal an article’s peer reviewers.

On Jan. 18, Judge Joel Wohlfeil of the Superior Court of the State of California in San Diego is scheduled to hold a hearing on whether or not the National Strength and Conditioning Association (NSCA) should be compelled to unmask the reviewers for “Crossfit-based high-intensity power training improves maximal aerobic fitness and body composition.”

The article was published in 2013 in the Journal of Strength and Conditioning Research (JSCR), the official research publication of the NSCA, and was retracted last year. It’s referred to as the “Devor article” in the court documents, after last author Steven Devor, a former professor at The Ohio State University (OSU).

A “discovery referee” assigned to the defamation case recently ordered NSCA to provide CrossFit with the reviewers’ names, but NSCA is challenging those rulings, saying that they have the same right to protect their sources as journalists do.

Title: Sleep quality and body composition variations in obese male adults after 14 weeks of yoga intervention: A randomized controlled trial

What Caught Our Attention: Last year, researchers led by David Allison at the University of Alabama at Birmingham’s School of Public Health called for the retraction of an article linking weight loss and obese female yoga participants in the International Journal of Yoga, citing problems with randomization and baseline statistics. Despite the first author’s statement that he planned to retract the article, the journal refused to retract it.   Read the rest of this entry »

“A concerning – largely unrecognised – threat to patient safety:” Nursing reviews cite retracted trials

with 10 comments

Richard Gray

Too many papers cite retracted research — even after it’s been retracted. It’s a problem. It can be especially a problem in clinical fields, where patient care is at stake. Recently, Richard Gray at La Trobe University in Australia and his colleagues examined the scope of the problem in the nursing field, noting how many systematic reviews included findings from retracted clinical trials. We spoke with Gray about their findings, published in the International Journal of Nursing Studies — and what they might mean for the safety of patients.

Retraction Watch: Retractions are a concern in any field, but as you note, when clinical practice is at stake, it can be particularly worrisome. Do you think your findings raise any potential concerns about patient safety?
