Lacking “scientific and analytical rigor,” 8-year-old lymphoma paper falls to retraction

leuklympjuly13Leukemia & Lymphoma has retracted 2004 paper by a group of authors in Mexico after concluding that, well, the article never should have been accepted to begin with.

The article, “Adjuvant radiotherapy in stage IV diffuse large cell lymphoma improves outcome,” came from oncologists at the National Medical Center. Its abstract (still available on Medline) states: Continue reading Lacking “scientific and analytical rigor,” 8-year-old lymphoma paper falls to retraction

Updated: Integrity “uncertain,” journal retracts stroke paper

emmcover

Experimental & Molecular Medicine has retracted a 2012 paper on stroke by a group of South Korean researchers after learning that one of the figures in the article was unreliable.

The article was titled “Protective effects of transduced Tat-DJ-1 protein against oxidative stress and ischemic brain injury,” and it came from a team at Hallym University in Chunchon.

According to the retraction notice: Continue reading Updated: Integrity “uncertain,” journal retracts stroke paper

Madoff retracts scientific paper

dcrectNo, not that Madoff.

We’re talking about Robert Madoff, editor of Diseases of the Colon & Rectum. His journal is pulling a 2012 paper by a group of authors in Spain who seem to have been unable to back up their findings when they were found to contain errors.

The article, “Perianal versus endoanal application of glyceryl trinitrate 0.4% ointment in the treatment of chronic anal fissure: results of a randomized controlled trial. Is this the solution to the headaches?” looked at what evidently is a significant side effect of nitroglycerin treatment for anal fissures: headaches. According to the abstract:

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

Two cancer papers retracted because authors “are unable to guarantee the accuracy of some of the figures”

cancer lettersA team of researchers in Ireland has retracted two papers from Cancer Letters after concerns were apparently raised about some of the studies’ figures.

Denise Egan, of the Institute of Technology Tallaght in Dublin, and colleagues published “In vitro anti-tumour and cyto-selective effects of coumarin-3-carboxylic acid and three of its hydroxylated derivatives, along with their silver-based complexes, using human epithelial carcinoma cell lines” and “A study of the role of apoptotic cell death and cell cycle events mediating the mechanism of action of 6-hydroxycoumarin-3-carboxylatosilver in human malignant hepatic cells” in 2007.

The two notices say the same thing: Continue reading Two cancer papers retracted because authors “are unable to guarantee the accuracy of some of the figures”

Authors retract already-corrected Nature malaria paper

Nature is retracting a 2010 paper by a team from Princeton and Drexel on the workings of Plasmodium falciparum, which causes malaria in people. How that came about seems to have been a winding road.

The article — a research letter — titled “Branched tricarboxylic acid metabolism in Plasmodium falciparum,” came from the Princeton lab of Manuel Llinás. It purported to find that:

Without “confidence in the conclusions,” group retracts prostate cancer paper

redjournalBack in January, we wrote about the retraction of a paper in the International Journal of Radiation Oncology *Biology* Physics, the first from that journal in its 38-year history.

At the time, the journal’s new editor, Anthony Zietman, of Mass General, told us that he was working on a second retraction. That one has arrived.

The paper, “High-Dose Conformal Radiotherapy Reduces Prostate Cancer–Specific Mortality: Results of a Meta-analysis,” came from a team of radiation oncologists in Brazil, and was published last August.

According to the retraction notice:

“Way out there” paper claiming to merge physics and biology retracted

dna cell biologyA German professor who claims to have developed “a self-consistent field theory which is used to derive at all known interactions of the potential vortex” will have at least two papers retracted, thanks to the scrutiny of a concerned economist.

The first retraction has already appeared, in DNA and Cell Biology, for a paper by Konstantin Meyl called “DNA and Cell Resonance: Magnetic Waves Enable Cell Communication.” The notice says nothing: Continue reading “Way out there” paper claiming to merge physics and biology retracted

University of Minnesota swine flu researcher under investigation for alleged misconduct

In late December, we reported on the retraction of a 2010 research letter in Emerging Infectious Diseases looking at the genetics of swine flu.

The notice in the journal, a CDC publication, indicated that the conclusions were in error, although it didn’t really say much more:

To the Editor: We would like to retract the letter entitled “Triple Reassortant Swine Influenza A (H3N2) Virus in Waterfowl,” which was published the April 2010 issue of Emerging Infectious Diseases (1). The nucleoprotein gene sequences from the viruses reported in that letter are very closely related to those from the earliest detected triple reassortant swine influenza viruses [CY095676 A/sw/Texas/4199–2/1998(H3N2)]. Although these viruses could have acquired a swine-origin segment, the branch lengths are quite short for 9 years of evolution. Therefore, we have withdrawn these 4 isolates from GenBank and subsequently retract this letter.

As it happens, there was more to the story.

Facebook study retracted after authors request substantial changes

cyberpsychThe journal Cyberpsychology, Behavior, and Social Networking is retracting a paper about Facebook.

“Bridging the Gap on Facebook: Assessing Intergroup Contact and Its Effects for Intergroup Relations,” is by Sandy Schumann of the Free University of Brussels. The notice says only:

This article has been officially retracted from the Journal.

We asked journal editor Brenda K. Wiederhold for more information about the retraction, and she responded: Continue reading Facebook study retracted after authors request substantial changes
