In the world of scientific misconduct, it’s often worth keeping track of what happens to scientists whose papers were retracted because of falsified or otherwise fraudulent results.
Take the case of Hung-Shu Chang. Last week, the the federal Office of Research Integrity announced that it had closed its investigation into the scientist’s misdeeds. Chang was a visiting postdoctoral researcher from Taiwan who in 2005 had come to the renowned Skinner Laboratory at Washington State University to study the effects of endocrine disruptors — a class of compounds that includes BPA and which have been shown to disrupt the action of hormones — on sex cells.
Chang was accused of falsifying data in a 2006 paper in Endocrinology — later retracted — reporting the damaging effects of vinclozolin, a fungicide used to protect vineyards, on the genetic integrity of sperm cells.
Citing “authorship” issues, a parasitology journal has retracted a paper by a Kenyan scientist which showed that Limburger cheese and milk cream may be effective mosquito bait.
The paper, by Eunice Owino, of the University of Nairobi, was published online in Parasites & Vectors this June but retracted in late August after the editors quickly learned that Owino had neglected to list several other authors on her manuscript.
Yesterday we reported on a retraction in a European liver journal involving post-acceptance shenanigans by a group of German researchers including a father and son, Axel and Olav Gressner. Well, it turns out there’s a bit more there there.
Didier Samuel, editor-in-chief of the Journal of Hepatology, where the team’s letter to the editor was retracted, tells Retraction Watch he was contacted earlier this year by the University of Aachen. The university was investigating potential misconduct by Olav Gressner. The journal launched its own inquiry, leading to the retracted letter, Samuel says.
Work from a prolific father-son team of liver researchers in Germany has come under scrutiny after accusations that they falsified data in a 2009 letter to the editor that appeared in the Journal of Hepatology.
The letter, retracted in the September issue (after an online notice in June), referred to a 2008 article in the journal by Axel Gressner, his son Olav, and their colleagues at University Hospital in Aachen in which the authors reported that doses of caffeine might be an effective treatment for liver fibrosis, scarring of the organ that results from chronic ailments such as cirrhosis or hepatitis.
Epidemiologic evidence has suggested that people who drink coffee are somewhat protected from liver fibrosis—although some experts dispute the purported connection—and the German group claimed to have been among the first to find a plausible molecular mechanism for the link. Their November 2008 paper on the subject has been cited 16 times, according to Thomson Scientific’s Web of Science, a hefty number for just 22 months.
In their follow-up letter, they went a step further, stating that injecting rats with caffeine blocked the expression of a key protein associated with growth of connective tissue necessary for the formation of liver scars.
Aging & Mental Health “welcomes original contributions” to fill its pages.
Or not so original. Last November, the journal published a study by two California researchers which looked at the possible effects of post-traumatic stress disorder on physical well-being in older women – and found no evidence of such a link.
Blaming “data coding errors,” the Journal of Occupational and Environmental Health has pulled an article linking shift work, age and sleeping problems.
The study was published four months ago, but managed in its brief lifespan to garner significant attention in the mainstream media and the blogosphere, although it has not been cited by any other papers. It comes alongside growing interest in the potential lnks between shift work and various health conditions including irritable bowel syndrome and breast cancer. Denmark even awards damages to shift workers who have developed the latter.
It might not be a first – although we can’t find another example — but a mental health journal has reinstated an article it retracted four years ago.
The retracted retraction notice appears in the August issue of the Journal of Neurology, Neurosurgery & Psychiatry, a BMJ title, and refers to a 2005 article describing an alarming case of treatment-related emotional problems in a patient with cluster headaches.
These headaches, which often strike behind the eyes, are akin to migraines and have been dubbed “suicide headaches” because they are so intensely painful that many sufferers have said that death would be a preferable fate. (Think: “It beats a poke in the eye with a sharp stick.”)
Sometimes redundancy — the topic of our last post — is a failure of editors to adequately vet a manuscript. Other times, the blame falls more squarely on the authors.
Consider: In the August 2010 issue of Anesthesia & Analgesia, a highly regarded specialty journal, five researchers from the University of Pennsylvania, led by Andrew Ochroch, made a remarkable confession.
Readers of three science publications may be wondering, “Where in the world were the editors?” after retractions appeared recently in the journals sounding the same theme: The articles in question had too much “overlap” between previous publications.
For example, the Journal of Fish Biology notice reads, in part: “The retraction has been agreed due to overlap between this article and several previously published articles.”
