Like many of those papers, the American Journal of Respiratory and Critical Care Medicine is being flagged over concerns it is “unreliable.” Here’s more from the EOC:
Two retractions and three corrections have appeared for a group of Duke researchers that already have 10+ retractions under their belts.
The reasoning behind them echoes that which we’ve seen before in notices for Michael Foster and Erin Potts-Kant: Following an inquiry from the university, the journals were informed that some of the data or results weren’t reliable, and not all of the experiments could be repeated.
A colleague aware of the case said that researchers are still working to repeat experiments from papers by Potts-Kant and Foster. It is not known how many more papers might be corrected or retracted. Duke University is fully supporting the validation of these experiments, the source told us.
Foster has retired from Duke, a spokesperson for the university confirmed. Continue reading Five more notices for Duke pulmonary pair brings retraction tally into double digits
An investigation at Johns Hopkins University has uncovered several issues with the figures in two papers on a lung disease linked to smoking, one of which is highly cited.
The American Journal of Respiratory and Critical Care Medicine is retracting both papers, which examine the role of protein NRF2 in chronic obstructive pulmonary disease. But both contain spliced and duplicated figures, among other issues.
Both papers — which share a total of five authors — received an expression of concern in 2014, after the corresponding author noticed anomalies in the figures. That same year, PubPeer commenters had begun raising questions about some of the figures in one of the papers.
A spokesperson for Johns Hopkins declined to say whether the investigation considered if the errors were the result of misconduct.
All authors agreed with the retraction, except for one who couldn’t be located. Here’s more from the retraction note for both papers:
Data issues continue to plague pulmonary papers co-authored by Duke University professor William Foster and former Duke researcher Erin Potts-Kant. Yesterday, the American Journal of Respiratory and Critical Care Medicine posted an Expression of Concern for two articles from the pair while the findings are “under review.”
The notice was published after the paper’s corresponding author, John Hollingsworth (also at Duke), told the journal that “some of the data published in these articles may be unreliable,” a term that we’ve gotten used to seeing from previous retractions.
Another Expression of Concern from the journal published earlier this year for another paper co-authored by Foster and Potts-Kant turned into a retraction months later. Hollingsworth was a co-author on that paper and another paper retracted from Environmental Health Perspectives in July.
Authors were unable to replicate the experiments after “concerns about the initial data from the animal physiology laboratory” led them to reanalyze source data, according to the note in Environmental Health Perspectives. The comparison showed “potential inconsistencies in the data,” which “significantly impact the overall conclusions of the manuscript.” Similar issues appear to have felled the pair’s other papers, including the other two recent retractions in the American Journal of Respiratory and Critical Care Medicine and the American Journal of Physiology – Lung Cellular and Molecular Physiology — but in the latter case, the discrepancies don’t affect the conclusion.
Potts-Kant was arrested on embezzlement charges in 2013. Authorities alleged that she stole almost $15,000 from Duke University.
Environmental Health Perspectives posted a retraction in July, for a 2012 paper that looked at the molecular underpinnings in airways that react to ozone.

Last August, we reported on an Expression of Concern in the American Journal of Respiratory and Critical Care Medicine for a paper on HIV and lung injury. The notice said that the University of Nebraska, home to several of the paper’s authors, had begun an inquiry.
Today, the university issued a statement on the case, clearing the researchers of misconduct: Continue reading University of Nebraska clears HIV researchers of misconduct
The American Journal of Respiratory and Critical Care Medicine (AJRCCM) has issued an Expression of Concern about a paper published online earlier this year, after concerns about the data prompted an investigation by the University of Nebraska.
