87% of bugs resistant to antibiotics? Not so fast, as staph paper yanked after staff mistake

with 3 comments

What could have been a truly scary study about drug resistant staph infections in hospitals has been retracted due to a lab error.

6.coverResearchers at a community hospital in Pittsburgh claimed that the commonly quoted 3% rate of staph that is resistant to ceftriaxone and sensitive to methicillin was drastically understated. However, an “honest error in the interpretation of a key lab test” called the findings into question.

Here’s the abstract: Read the rest of this entry »

Authors ask Science to retract Hayabusa asteroid paper

with 13 comments

jaxa_logoThe Japan Aerospace Exploration Agency (JAXA) has requested that Science retract a 2006 paper about the makeup of asteroid Itokawa as observed from the spacecraft Hayabusa, the news section of Science reports.

Instead of calibrating their equipment on Earth, the scientists assumed they’d see both magnesium and silicon in the x-ray spectra, and used that assumption to assess the rest of the chemical composition of the asteroid.

The paper may be based on faulty assumptions, but the conclusions have been backed up by other published papers, according to the Science magazine report: Read the rest of this entry »

Diabetes researchers retract, correct and republish study on mortality rates

with 9 comments

diabetologiaA diabetes paper that received quite a bit of media attention when it was published in June 2013 was retracted and reissued to fix data errors shortly after publication.

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 »

Paper on liver failure in babies withdrawn for lab mix-up

leave a comment »

jpgnA paper on liver failure in infants has been retracted due to a lab error, though the author contends that the paper still holds a valuable message for pediatricians — one that could save lives.

To get to that, though, we had to make it through what turns out to be an unnecessarily vague retraction notice (more on that in a moment) in the Journal of Pediatric Gastroenterology & Nutrition:

Article about alcohol withdrawal withdrawn

with 3 comments

A stumble in data preparation earned a retraction for a paper on delirium tremensalcohol_and_alcoholism, a life-threatening side effect of alcohol withdrawal that spans a wide range of symptoms, including hallucinations and seizures.

Though the initial retraction notice was extremely unhelpful, the author stepped in to give us a better picture of the errors that led to the paper’s demise.

Here’s the notice from Alcohol and Alcoholism about “Biochemical Predictors of Delirium Tremens in Patients in Alcohol Withdrawal”:
