A pair of expressions of concern in PLOS ONE over vet science papers

PLoS ONE has issued two Expressions of Concern on unrelated studies, each of which offers plenty to be concerned about — and not just about the research itself.

One is a casualty of our old friend,  Jesús Lemus, the Spanish veterinary scientist accused of fabricating his data.

The article, titled “The PHA-Skin Test Reflects Acquired T-Cell Mediated Immunocompetence in Birds,” was published in September 2008 and cited 61 times, according to Google Scholar.

Back in April, the publisher posted this comment to the paper: Continue reading A pair of expressions of concern in PLOS ONE over vet science papers

PLoS ONE retracts paper on treatment of tissue disease for lack of ethical approval, erroneous data

PLOS ONE has retracted an article it published earlier this year by a group from Australia who failed to receive adequate ethics approval for their study.

The paper, “Late Complications of Clinical Clostridium Histolyticum Collagenase Use in Dupuytren’s Disease,” came from Warren M. Rozen, Yasith Edirisinghe and John Crock (sorry, irony machine not working today). Dupuytren’s causes thickening of the fascia in the hands and often requires surgery.  In 2011 the FDA approved a treatment for the ailment that involves injections of an enzyme — Clostridium Histolyticum Collagenase, or CHC — into the affected area.

The Aussie article looked at the effects of CHC injections in 12 patients over one year, finding that two of the patients suffered Continue reading PLoS ONE retracts paper on treatment of tissue disease for lack of ethical approval, erroneous data

Lemus, Stapel each rack up another retraction

The retraction counts keep mounting for two Retraction Watch frequent flyers.

First, Diederik Stapel’s 26th retraction, according to our count. Psychologist Stapel admitted to making up data in dozens of studies, and is also facing a criminal inquiry for misuse of funds.

Here’s the notice: Continue reading Lemus, Stapel each rack up another retraction

Most retraction notices don’t involve research misconduct or flawed data: new study

October, apparently, is “studies of retractions month.” First there was a groundbreaking study in PNAS, then an NBER working paper, and yesterday PLoS Medicine alerted us to a paper their sister journal, PLoS ONE, published last week, “A Comprehensive Survey of Retracted Articles from the Scholarly Literature.”

The study, by Michael L. Grieneisen and Minghua Zhang, is comprehensive indeed, reaching further back into the literature than others we’ve seen, and also including more disciplines: Continue reading Most retraction notices don’t involve research misconduct or flawed data: new study

High school whiz kid retracts PLoS ONE herd immunity paper

Georgette speaking at the Davidson Institute’s award ceremony, Library of Congress, 2008

It’s pretty impressive to publish two peer-reviewed papers on complicated vaccination models while you’re still in high school. So it’s not surprising that Nathan Georgette, who grew up outside of Jacksonville, Florida, earned a prestigious fellowship from the Davidson Institute for Talent Development.

But perhaps even more impressive is realizing you’ve made a fundamental error in one of those studies, and retracting it while you’re still a college senior at Harvard. Continue reading High school whiz kid retracts PLoS ONE herd immunity paper

Feeling sheepish: Another retraction for Lemus, of study of whether livestock can spread chlamydia to birds

Jesús A. Lemus, the Spanish veterinary researcher whose work has been the subject of a misconduct inquiry, has another retraction for his CV. It’s his third, according to our count.

The newest retraction is from PLoS ONE:

Walk (back) an Egyptian (vulture): Another paper by Spanish vet under scrutiny retracted

With apologies to the Bangles for this post’s title, we have another vulture-related retraction from Jesús A. Lemus, the Spanish veterinary researcher whose results have come into question.

This one involves a paper that appeared in PLoS ONE in 2009, titled “Susceptibility to Infection and Immune Response in Insular and Continental Populations of Egyptian Vulture: Implications for Conservation.”

According to the notice: Continue reading Walk (back) an Egyptian (vulture): Another paper by Spanish vet under scrutiny retracted

Immunology paper retracted because “documents were not archived with due diligence”

A group of researchers from Austria, Canada, Germany, and the U.S. have retracted a 2008 paper in the Journal of Immunology after being unable to verify the contents of some key figures.

Here’s the notice: Continue reading Immunology paper retracted because “documents were not archived with due diligence”

The authors of a paper suggesting that cassava, a starchy vegetable that’s a major food source in much of the developing world, could one day be turned into a food staple “capable of supplying inexpensive, plant-based proteins for food, feed and industrial applications” have retracted it, following an institutional investigation that failed to find critical supporting data.

Here’s the notice for the PLoS ONE study, “Transgenic Biofortification of the Starchy Staple Cassava (Manihot esculenta) Generates a Novel Sink for Protein:” Continue reading PLoS ONE GMO cassava paper retracted after data “could not be found”

PLoS ONE has issued an expression of concern over a  2010 paper by Chinese scientists about how the immune system responds to the vaccine against the swine flu.

The article, “Protection Induced on Day 10 Following Administration of the 2009 A/H1N1 Pandemic Influenza Vaccine,” claimed to study 58 subjects given the inoculation (more on that below) and that Continue reading PLoS ONE expresses concern over flu vaccine paper
