Journal takes down autism-vaccine paper pending investigation

with 51 comments

translational neurodegenerationAn article purporting to find that black children are at substantially increased risk for autism after early exposure to the measles-mumps-rubella vaccine has been shelved.

Although we don’t know if the events are related, the move comes amid claims that a CDC whistleblower has accused health officials of suppressing information about the link.

Not surprisingly, the prospect that the CDC has been sitting on evidence of an autism-vaccine connection for more than a decade has inflamed the community of activists wrongly convinced that such a link exists.

The paper, “Measles-mumps-rubella vaccination timing and autism among young african american boys: a reanalysis of CDC data,” was written by Brian Hooker, an engineer-turned-biologist and an active member of that community. It was submitted in April, accepted on August 5, and published on August 8.

“Our jaws hit the floor!!” Researchers say authors doctored images for rebuttal letter

with 7 comments

eurourologyTry to follow along on this one. We think it’s worth it.

The authors of a letter replying to a comment in a urology journal have retracted their response because it contained inappropriate figures. At least, that’s the official story.

The original paper, “Effect of a Risk-stratified Grade of Nerve-sparing Technique on Early Return of Continence After Robot-assisted Laparoscopic Radical Prostatectomy,” came from a group at Weill Medical College of Cornell University led by Ashutosh Tewari. Published in July 2012 in European Urology, it purported to find that: Read the rest of this entry »

The paper, titled “Further Pieces of Evidence to the Pulmonary Origin of Sevoflurane Escaping to the Operating Room During General Anaesthesia,” appeared in Cell Biochemistry and Biophysics and came from a group at various institutions in Harbin, China.

But according to the retraction notice, the further pieces weren’t really further, after all:

Journal that “suffered” from plagiarism purges itself

with 7 comments

pharmpractWhen Pharmacy Practice found out it had been victimized by plagiarists, it apparently took the news personally — and to heart.

In an elaborate statement with more than a dozen references — but not one to the plagiarizing work — the journal lashed out against the behavior of word thieves, and described the discovery as a Road to Damascus moment.

Here’s the notice, which was published in 2012 but was only just indexed on PubMed:

Here’s the retraction notice for “Mortality trends in patients with and without diabetes in Ontario, Canada and the UK from 1996 to 2009: a population-based study”: Read the rest of this entry »
