Talk about a popular patient: A woman who developed a case of internal bleeding while taking the anticoagulant Xarelto (rivaroxaban) was written up in not one — but two — case reports. The trouble was, both groups didn’t realize what the other was doing, so the more recent article is now being retracted from the Journal of Clinical Pharmacy and Therapeutics.
The authors, a trio of doctors at Sakarya University in Turkey, described the case of a 75 year-old woman who came to the emergency room for fatigue and stomach pain after taking rivaroxaban for three days. A scan revealed a rectus sheath hematoma.
However, the case had already been published a few months earlier in the Indian Journal of Pharmacology by a separate group of doctors from Sakarya, along with authors from Yenikent State Hospital and Vakfikebir State Hospital.
Over a decade ago, a case report on a woman with cervical cancer and lymphoma was “published twice” by the International Journal of Gynecological Cancer within the span of a few months. The retraction note came out just now.
One copy of the paper appeared in the July 2003 issue of the journal. The second, now-retracted, copy — “Coincidental detection of T-cell rich B cell lymphoma in the para-aortic lymph nodes of a woman undergoing lymph node dissection for cervical cancer: A case report” — was published later that year, in the September issue.
There are just a few cosmetic differences between the headlines and abstracts of the papers — a “;” instead of a “,”; a change in verb tense, and a typo, for instance. (See a text comparison of the abstracts here.)
Desalination and Water Treatment has retracted a paper it published in January by a pair of Turkish researchers for “irregularities in the methodology and data management.”
The article, “Molecular simulation of Zn2+, Cu2+, Pb2+, and NH4+ ion-exchange in Clinoptilolite,” investigated how well different natural forms of the zeolite Clinoptilolite remove heavy metals from wastewater. It came from the lab of Mehmet Göktuğ Ahunbay, of Istanbul Technical University, accompanied by first author Barış Demir.
A pair of plant experts at Uludag University, in Turkey, has lost a paper on techniques for drying parsley because they evidently left a key contributor off the manuscript.
The article, “Effect of Vacuum, Microwave, and Convective Drying on Selected Parsley Quality,” was published online in June 2011 by the International Journal of Food Properties.
During the study, the authors subjected parsley (Petroselinum crispum Mill.) to the various drying techniques, then measured how much each degraded the sample. Ascorbic acid — a particularly “important indicator of quality,” according to the authors — was lowest after convective drying, and highest after using the microwave. “At the end of the study, microwave drying at 750–850 W ensured the shortest drying time and the best overall quality of parsley; thus, it was chosen as the most appropriate technique for parsley drying.”
In the notice, the journal states that “significant portions” of the findings in “Association of anti-Mullerian hormone and small-dense low-density lipoprotein cholesterol with hepatosteatosis in young lean women with and without polycystic ovary syndrome” already appeared in another paper. Three authors appear in both publications, all based at the University of Ufuk (don’t think too hard about that name) in Ankara, Turkey.
