When two surgeons in Greece learned that a patient had developed a rare side effect following weight loss surgery, they were eager to publish the case.
After extensive testing, the patient was diagnosed with Wernicke’s encephalopathy—a neurological disorder caused by thiamine deficiency—following a sleeve gastrectomy procedure. As the authors note in the paper, they had seen only eight other cases following the procedure in the literature.
It turns out, theirs was not the ninth. After the patient unfortunately died, he was examined by a coroner, who ruled he did not, in fact, have Wernicke’s encephalopathy. So Dimitrios Manatakis and Nikolaos Georgopoulos, both based at Athens Naval and Veterans Hospital in Greece, have retracted their 2014 case study.
When the first learned of the patient, the authors wanted to alert the surgical community to the case, given the rarity of this side effect, Manatakis told us: Continue reading Patient misdiagnosed with rare neurological side effect in retracted case study
A researcher in Greece has issued extensive — what we sometimes call “mega” — corrections to two 2016 papers published in a medical journal in Romania.
The first author — Alexandra Kalogeraki, a pathology researcher at the University of Crete in Greece — retracted two reviews from the same journal last year for plagiarism. The newest notices remove authors and correct, add, or remove text, often without providing an explicit reason for the change.
The journal told us Kalogeraki initially asked to retract the newly corrected papers, but the editors didn’t believe that the papers warranted the harsher measure, as they’d run a plagiarism scan and conducted peer review of the two papers and did not find any issues. However, the University of Crete is currently investigating allegations of plagiarism in two of Kalogeraki’s other papers, which have already been retracted by the same journal.
For the latest mega-corrections, both are so lengthy we’re only including a small portion of the notice for the case study, “Recurrent Cerebellar Desmoplastic/ Nodular Medulloblastoma in Cerebrospinal Fluid (CSF) in the elderly. A Cytologic Diagnosis,” which deals with authorship: Continue reading Researcher issues massive changes to papers amidst plagiarism investigation
A medical journal in Romania has issued a lifetime ban for a researcher after retracting four of his papers.
Since April, the Romanian Journal of Internal Medicine (RJIM) retracted nine papers (eight for plagiarism, one for duplication); four of these were co-authored by Manole Cojocaru, a researcher at the Titu Maiorescu University (TMU) in Bucharest, Romania. Subsequently, the journal has banned Cojocaru from submitting manuscripts, and has also informed the ethics committee at his institution.
Here’s the retraction notice, which is the same for six of the papers: Continue reading Romanian journal bans author following 4 retractions
A publisher has retracted a chapter from a book on flow cytometry after determining the authors plagiarized some material — but noted that because the authors cited the article they lifted from, they likely acted “in good faith.”
We were tipped off to this retraction from the authors of the review article the chapter plagiarized from, who told us they were upset by the incident and doubted whether the authors had performed the experiments they described in the chapter.
More broadly, the retraction raises an important question: How can publishers retract one chapter of a book, leaving the rest intact?
First, let’s take a look at the retraction notice: Continue reading Book publisher: Authors plagiarized “in good faith” because they cited previous work
A paper whose expression of concern we covered in November 2014 has been retracted and republished “because of the extent of the changes necessary,” according to the Lancet Respiratory Medicine.
This isn’t the first time we’ve seen retraction/republications at the Lancet, accompanied by thorough breakdowns of the problem.
This study was a meta-analysis of research on how the timing of tracheostomies — placing a breathing tube directly into the windpipe — affects patients’ mortality rate. The original paper found that critically ill patients who received a tracheostomy earlier fared better than those for whom the procedure was delayed for weeks after intubation, the recommended practice.
However, when the authors calculated how many patients died, they assumed that any patient who wasn’t discharged from the intensive care unit (ICU) had died there, instead of looking for other explanations. This made their estimates unreliable.
The publisher convened a panel, which ultimately decided retraction and republication was the most appropriate course of action.
The original expression of concern contained a quote from the authors about the “data discrepancy” that would later sink the paper: Continue reading Retraction and republication for Lancet Resp Med tracheostomy paper
The journal Food Microbiology has pulled a 2012 paper on pork processing which, as we reported earlier, contained salami-sliced data.
The article, “Bayesian inference for quantifying Listeria monocytogenes prevalence and concentration in minced pork meat from presence/absence microbiological testing,” came from a group at the Department of Food Science and Technology at the Agricultural University of Athens, in Greece.
According to the notice: Continue reading Unkosher reuse of data forces retraction of minced pork paper
Lancet Respiratory Medicine has issued an expression of concern for a meta-analysis on tracheostomy in the intensive care unit that they published earlier this year.
The paper, “Effect of early versus late or no tracheostomy on mortality of critically ill patients receiving mechanical ventilation: a systematic review and meta-analysis“, came from a group at Harvard, Weill Cornell and the University of Athens. The authors purported to find that: Continue reading Lancet journal puts ICU paper on watch after authors acknowledge potentially fatal flaw
Nephrology Dialysis Transplantation has retracted a 2014 meeting abstract by a group of researchers on Crete whose ranks were inflated by one.
The abstract, titled “GENOTYPE (A) OF ENOS GENE AND R229Q MUTATION OF NPHS2 APPEARS TO BE ASSOCIATED WITH A WORSE OUTCOME IN PATIENTS WITH IGA NEPHROPATHY,” was presented at the European Renal Association-European Dialysis Association’s annual meeting.
Here’s what it reported: Continue reading Kidney journal pulls abstract for author issues
A group of researchers have lost a paper in a computer science journal because they were apparently using its references to help the impact factor of a different journal that one of them edits.
Here’s the notice for “Impacts of sensor node distributions on coverage in sensor networks,” a paper first published in 2011 and cited four times, according to Thomson Scientific’s Web of Knowledge: Continue reading Citation manipulation: Journal retracts paper because author boosted references to a journal he edits
The editor of a psychology journal has had seven papers in a different psychology journal retracted, for either plagiarism or duplication, although the notices are vague.
Here are the seven articles by Paraskevi Theofilou, editor of Health Psychology Research, in Europe’s Journal of Psychology: Continue reading Psychology journal editor has seven articles retracted for duplication or plagiarism
