Corrections chip away at asbestos paper for conflicts of interest, “misleading” citation

EBPHThe journal Epidemiology Biostatistics and Public Health has issued back-to-back corrections for a 2015 paper after the authors failed to disclose conflicts of interest with the asbestos industry and included an “erroneous citation.”

The mistaken citation was more than just a clerical error, critics argue — it undermines one of the key arguments of the paper, “Critical reappraisal of Balangero chrysotile and mesothelioma risk,” which disputes claims that an asbestos mine in northwest Italy was responsible for numerous cases of an aggressive form of cancer called mesothelioma. The authors, led by Edward Ilgren formerly of Oxford University, claim that “myriad sources” of other forms of asbestos—rather than the asbestos produced at the mine, called chrysotile—exist in the region “to account for the alleged cases.”

However, according to a recently added correction, the citation does not support one of the authors’ claims about how other forms of asbestos arrived at the mine area.

CDC fixes major error in flooring risk report: Not converting to metric

CDCThe U.S. Centers for Disease Control and Prevention issued a correction notice to a report about formaldehyde in laminate flooring, saying a mistake had caused them to significantly underestimate the health risks.

The mistake: According to CBS’s 60 Minutes, the CDC sometimes didn’t convert feet to meters. Ouch.

In the corrected report, the agency estimates the health risks of the laminate flooring — by irritating the ear, nose and throat — to be three-fold higher than what they suggested in the original report, published February 10.

Here’s the note that now appears in the link to the original CDC report: Continue reading CDC fixes major error in flooring risk report: Not converting to metric

Johns Hopkins investigation leads to retraction of two lung papers, one highly cited

showCoverImageAn 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:

List of retractions, corrections grows for Duke researchers

cov200hDuke researcher Michael Foster and his former co-author Erin Potts-Kant are adding to their notice count with a major correction from late last year to a paper on how certain cells in mice respond to a pneumonia infection, citing “potential discrepancies in the data.”

The correction is actually a partial retraction: The note explains that parts of three figures should be discounted.

We’ve also recently unearthed multiple corrections and two retractions from the pair that we missed from earlier in 2015.

After questions about the data in the corrected paper arose, the authors were able to replicate most of the experiments in the paper, according to the note. But since the paper was published, the senior author passed away, closing her lab, so they couldn’t repeat all of the work.

Here’s the correction notice for “Mast cell TNF receptors regulate responses to Mycoplasma pneumoniae in surfactant protein A (SP-A)−/− mice,” published in The Journal of Allergy and Clinical Immunology:

We have a new record: 80 years from publication to retraction

cover_2015_51We have a new record for the longest time from publication to retraction: 80 years. It’s for a case report about a 24-year-old man who died after coughing up more than four cups of what apparently looked — and smelled — like pee.

According to the case report titled “Een geval van uroptoë” published in 1923, an autopsy revealed that the man had a kidney that was strangely located in his chest cavity. A case of pneumonia caused the kidney to leak urine into the space around his lungs, leading to the perplexing cough.

If that sounds too crazy to be true, you’re right: This man never existed. The case was retracted in 2003. (Yes, we are a little late to this one — it recently popped up in one of our Google alerts.)

A write-up by the editors of the Nederlands Tijdschrift voor Geneeskunde — that translates to “Dutch Journal of Medicine” — explains that the strange case was a fake (on the fifth page of this PDF, in English):

Plagiarism was “not an intentional act,” says first author of retracted TB paper

logoA 2013 review article about tuberculosis is being retracted for “unacknowledged re-use of significant portions of text” from another article, which the first author said wasn’t intentional.

Sayantan Ray, based at Medical College and Hospital, Kolkata in India, told us that “most of the unchanged text” is present in sections written by junior co-authors. Since there doesn’t appear to be any attempt to cover it up, he argued anyone responsible for the plagiarism must not have realized it was wrong:

You can appreciate that this type of obvious similarity can only happen when the concerned person [does] not have any idea about [the] plagiarism issue.

According to the notice, published by Therapeutics and Clinical Risk Management, most of the re-used text appears to have come from a 2012 paper in the Indian Journal of Medical Research. Here’s more from the notice:

Journal bans authors of duplicated asthma paper

22A common ailment known as duplication has taken down a paper about a common fungus and asthma.

Aspergillus spores are often ubiquitous yet harmless, but can irritate people whose lungs aren’t in top working order. Duplication, on the other hand, is more universally deadly. The editors of The Pan African Medical Journal told us that, in addition to the retraction, there were personal consequences for the authors:  Continue reading Journal bans authors of duplicated asthma paper

Duke researcher with 7 retractions earns two Expressions of Concern

American Journal of Respiratory and Critical Care MedicineData 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.

Retraction no. 8 (and a 1/2) hits former Duke researcher Erin Potts-Kant

American Journal of Physiology - Lung Cellular and Molecular PhysiologyAnother retraction and a correction that retracts two figures — ie, a partial retraction — have been posted for Duke University lung researchers, Erin Potts-Kant and Michael Foster.

These latest notices move the count up to 8.5 retractions for Potts-Kant and 7.5 for Foster (counting the partial retraction as 1/2), along with the correction for both. In both cases and in a familiar note from previous retractions, authors found “potential discrepancies” between two sets of data (partial retraction) and study figures that weren’t “reliable” (retraction).

The retraction comes after the authors discovered problems with three of the study figures. In the corrected paper, the authors were able to validate some of their findings after repeating the experiments, but retracted two of the study figures that they were “unable to verify.”

Duke lung researcher up to seven retractions

Enviromental Health Perspectives

More journals have pulled papers co-authored by researchers Erin Potts-Kant and Michael Foster, at Duke University, bringing the total up to seven for Potts-Kant and six for Foster.

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.

Here’s the full notice:
