Nutrition researcher Chandra loses libel case against CBC

CBCThe self-proclaimed “father of nutritional immunology,” Ranjit Kumar Chandra, has lost a libel lawsuit against the Canadian Broadcasting Company (CBC).

The suit was in response to a 2006 three-part documentary from the CBC, which examined allegations of fraud against the former Memorial University researcher.

After the 58-day trial, the Ontario Superior Court of Justice “ruled in favour of CBC, on the grounds that the words in the broadcast were true,” according to CBC producer Lynn Burgess: Continue reading Nutrition researcher Chandra loses libel case against CBC

Panel says BMJ was right to not retract two disputed statin papers

bmjA panel reviewing The BMJ‘s handling of two controversial statin papers said the journal didn’t err when it corrected, rather than retracted, the articles.

The articles — a research paper and a commentary — suggested that use of statins in people at low risk for cardiovascular disease could be doing far more harm than good. Both articles inaccurately cited a study that provided data important to their conclusions — an error pointed out vigorously by a British researcher, Rory Collins, who demanded that the journal pull the pieces.

In a letter to Godlee this spring, Collins wrote: Continue reading Panel says BMJ was right to not retract two disputed statin papers

Second paper falls for ex-Leiden researcher accused of fraud

BMJ authors take back inaccurate statin safety statements

bmjcover514Last October, the BMJ published a paper by a group of researchers from the United States and Canada questioning the use of statins in patients considered at low risk of cardiovascular disease.

The article has been cited eight times since then, according to Thomson Scientific’s Web of Knowledge. It mentioned data from another study that reported a high rate of side effects in patients who used the drugs, between 18% and 20% — suggesting that those who received little or no benefit from the therapy could be more more likely to suffer harm than good.

But that citation turns out to have been flawed — prompting the journal to take the unusual step of removing those “statements” from the article and another it published about the issue that has been cited six times. And in an editorial, BMJ editor Fiona Godlee said she has asked a panel of experts to review the original paper to determine if it ought to be retracted completely: Continue reading BMJ authors take back inaccurate statin safety statements

Last week, we reported that some of the authors of a 2010 paper in the BMJ claiming to have identified Henry IV’s head thought the study should be retracted based on new evidence. Some of the other authors have now responded to that call for retraction, which appeared on the BMJ’s site alongside the paper.

Philippe Charlier, the corresponding author of the original paper, and five of the original paper’s 15 co-authors conclude after reviewing the evidence that

The BMJ is well-known for its annual Christmas issue, which New York Times medical correspondent Lawrence Altman calls

a lighter and sometimes brighter side of medicine, publishing unusual articles that vary from simply amusing to bizarre to creative or potentially important.

The 2010 issue was no exception, featuring a paper called “Multidisciplinary medical identification of a French king’s head (Henri IV)” in which: Continue reading Off with his paper! Some authors want to retract claim to have identified Henry IV’s head
