Hip, hip, retract! Cobalt poisoning case study pulled as duplicate

hipinternationalHip International has retracted a case study for duplication. (We apologize for the partial duplication of a headline for an earlier post about this journal, which told readers that “Similar cases will be referred to retractionwatch.”)

The article was titled “Chronic intoxication with cobalt following revision total hip arthroplasty,” and it appeared online ahead of print. Cobalt toxicity associated with metal-on-metal replacement hips has been raised as a potential adverse effect from the devices.

Paper by fake cardiologist retracted

j patient safetyRetraction Watch readers may recall the case of William Hamman, the United Airlines pilot who claimed to be a cardiologist until the Associated Press uncovered him in late 2010. Hamman had published at least six papers, and since the revelations has had one retraction and one erratum, by our count.

Now comes another retraction, in the Journal of Patient Safety. Here’s the (paywalled) notice, signed by journal editor Charles Denham: Continue reading Paper by fake cardiologist retracted

Musical figures: PNAS paper corrected with version of “intentionally contrived and falsified” Nature figure

pnasOne of the two corrections recommended by a McGill committee for work by Maya Saleh and colleagues has appeared, in the Proceedings of the National Academy of Sciences (PNAS).

As we reported last month, the committee found that

two figures in [a] Nature paper had been “intentionally contrived and falsified.” One of those figures was duplicated in a PNAS paper, which also contained an image that  had incorrectly labeled some proteins.

The committee recommended that both of the papers be corrected, and the PNAS correction  for “Confinement of caspase-12 proteolytic activity to autoprocessing” reads as follows: Continue reading Musical figures: PNAS paper corrected with version of “intentionally contrived and falsified” Nature figure
