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

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

CrossFit asks court to unmask peer reviewers of retracted study

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in 2013 in the Journal of Strength and Conditioning Research (JSCR), the official research publication of the NSCA, and was retracted last year.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.   Continue reading Caught Our Notice: “Ironically,” same error in same journal “was noted last year”

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

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?

Title: Patient Education After CABG: Are We Teaching the Wrong Information?

What Caught Our Attention: We’ve written about the controversy surrounding a commonly used tool to measure whether patients are sticking to their drug regimen, known as the Morisky Medication Adherence Scale (MMAS-8). It can cost thousands of dollars — and using it without payment/permission earns researchers a call from a collector, who has used legal threats to compel multiple teams to withdraw their papers (a phenomenon we wrote about in Science). The creator of the tool argues it’s copyrighted, and demanding fees ensures researchers use it properly, which avoids putting patients at risk. We’ve found a notice (paywalled, tsk-tsk) that reveals another group of authors used the tool without permission and, according to the notice, “incorrectly.”

RAND re-releases withdrawn report modelling child mistreatment

A think tank has re-issued a report on child welfare in the U.S., six months after it pulled the document amidst criticism from dozens of researchers.

The report offered policy recommendations for improving the child welfare system, based on numerical modeling conducted by researchers at the RAND Corporation.

RAND pulled the initial version of the report in June, after researchers — including Richard Barth, dean of the University of Maryland’s school of social work and Emily Putnam-Hornstein, of the University of Southern California — criticized the model for underestimating the rate of maltreatment over a child’s lifetime.

The report, reissued Dec. 11, contains updates detailing how the RAND researchers addressed the criticism. However, Jeanne Ringel, a senior economist at RAND and the study’s lead author, told us: Continue reading RAND re-releases withdrawn report modelling child mistreatment

Title: Ghanaians Might Be at Risk of Inadequate Dietary Intake of Potassium

What Caught Our Attention: Potassium-rich diets are thought to be “heart-healthy,” and after examining the average dietary habits of Ghanaian adults, researchers determined the average potassium (K) intake to be well below global standards.  However, the authors’ calculations of potassium intake per capita were too low by factor of 10, resulting in the incorrect conclusion that the average potassium intake was only 856 mg per day, an amount substantially lower than the World Health Organization (WHO) recommendation of 3510 mg/day.  The new calculations show an average K intake of 8,560 mg/day, well over the WHO guideline.  

We asked the corresponding author, David Oscar Yawson, about the source of the error, and he responded:

Title: Endotoxaemia during left ventricular assist device insertion: relationship between risk factors and outcome

What Caught Our Attention: Robert J. Frumento first caught our notice in 2013, as a coauthor on a paper retracted with a nonspecific reference to author misconduct.  Three years later, Frumento was clearly identified as having fabricated data and a master’s degree, and added three retractions to his name. Now he’s got a fifth retraction, this one citing missing data and a lack of proof that data blinding was performed correctly.   Continue reading Caught Our Notice: Columbia researcher up to five retractions

University requests 4th retraction for psychologist under fire

Jens Förster

The University of Amsterdam has requested another retraction for a prominent social psychologist, after reviewing the dissertations he supervised while at the university.

The university made the announcement this week after reviewing the theses supervised by Jens Förster, whose own work has been subject to considerable scrutiny.

The results of this investigation come more than two years after an initial probe into Förster’s work, which found several of his papers likely contained unreliable data; three of these papers have been retracted and four have received expressions of concern. Förster, who recently left his position at Ruhr-Universität Bochum in Germany to start a private psychology practice, has always maintained that he did not manipulate his data. In 2015, he turned down a professorship, citing the toll the investigation had taken. Continue reading University requests 4th retraction for psychologist under fire

Psychologist under fire leaves university to start private practice

Jens Förster

Jens Förster, a prominent social psychologist whose work has been subject to much scrutiny, recently left his position at Ruhr-Universität Bochum in Germany to start a private psychology practice.

We’ve verified with the university that Förster no longer works there, but the circumstances of his exit are not entirely clear. 

Förster’s research has faced considerable scrutiny in the past few years. A 2015 report describing an investigation into Förster’s work concluded that several of his papers likely contained unreliable data. Three of those papers have been retracted and four others have received expressions of concern. Förster, however, has denied allegations that he manipulated his data. In 2015, he turned down a prestigious professorship, citing the personal toll the investigation had taken. Continue reading Psychologist under fire leaves university to start private practice
