Heart pulls sodium meta-analysis over duplicated, and now missing, data

heart cover may13The journal Heart has retracted a 2012 meta-analysis after learning that two of the six studies included in the review contained duplicated data.  Those studies, it so happens, were conducted by one of the co-authors.

The article, “Low sodium versus normal sodium diets in systolic heart failure: systematic review and meta-analysis,” came from an eclectic group of authors from the United States, Canada and Italy (the first author is listed as being at a Wegmans pharmacy in Ithaca, N.Y.). The paper, published online in August 2012, purported to find that: Continue reading Heart pulls sodium meta-analysis over duplicated, and now missing, data

Scientists doing the right thing: Malfunctioning lab equipment leads to retraction of neuroscience paper

One-too-many authors scuttles paper on mouse metabolism

reg pepcoverRegulatory Peptides is retracting a 2010 paper by a group of five authors in China and one in Texas — and the presence of that last one was the problem.

The article, “Erythropoietin as a possible mechanism for the effects of intermittent hypoxia on bodyweight, serum glucose and leptin in mice,” had as its last (dare we say, senior) author Susan T. Howard, a mycobacterium expert at the University of Texas Health Science Center in Tyler. Trouble was, Howard disavowed any role in the paper.

According to the retraction notice: Continue reading One-too-many authors scuttles paper on mouse metabolism

Authors retract CT scan-cancer paper, citing faulty data

medicine coverA group of cancer researchers in Japan has retracted their 2011 paper in the journal Medicine. The reason: They seem to have had some trouble — well, perhaps a bit more than some — with their patient population.

The article, titled “Usefulness of systemic CT scanning in the detection of malignant lymphadenopathy,” came from the lab of Norio Komatsu, a hematologist at Juntendo University School of Medicine.

The paper’s no longer online, but we did find an abstract floating around: Continue reading Authors retract CT scan-cancer paper, citing faulty data

ORI finds former North Carolina company lab tech faked data in NIH grant

advanced liquid logicThe Office of Research Integrity has sanctioned a former technician at a North Carolina technology firm after concluding that the researcher fabricated data while working on a project funded by the National Institute of Allergy and Infectious Diseases.

The researcher, Matthew Poore, was a technician at Advanced Liquid Logic when he committed the misconduct, according to the report. While at North Carolina State University prior to his job at Advanced Liquid Logic, Poore published, by our count, 11 papers, one of which was cited more than 50 times, according to Thomson Scientific’s Web of Knowledge. The ORI report does not mention any of them.

Here’s what it does say: Continue reading ORI finds former North Carolina company lab tech faked data in NIH grant

Streisand Effect meets tough editors as journal retracts already-corrected paper by Rui Curi

Here’s the Journal of Endocrinology notice, whose headers and language are a bit confusing, understandably, because it is retracting two things, a correction and the original paper: Continue reading Streisand Effect meets tough editors as journal retracts already-corrected paper by Rui Curi
