A retracted periodontitis-heart disease paper that didn’t make it into the new AHA review

On Wednesday, the American Heart Association announced something that those of us who’d been reading the medical literature carefully had known for a while: Bad gums do not cause heart disease.

Periodontitis is linked to bad heart disease, you see, as studies have shown, and periodontists have sure been using this as an excuse to tell us to floss. But there’s never been a convincing study showing that one causes the other.

In fact, it’s not even clear how you’d do that study. “Let’s see, for a control group, we should have 100 people convince themselves they’re flossing for a year, but not actually floss….oh, what else can we get funding for?”

That “news” prompted an email from Retraction Watch friend Marc Abrahams, Continue reading A retracted periodontitis-heart disease paper that didn’t make it into the new AHA review

Whistling the same Tunisia: Serial plagiarists plague the oncology literature

A group of cancer researchers from Tunisia has been seeding the oncology literature with plagiarized articles that steal liberally — both text and data — from the work of others.

The group has one retraction, in the journal Obesity — whose splash page has the jaunty, if disconcerting, invite: “Welcome to Obesity!” — and at least two withdrawn papers. However, we have been alerted to at least one other case of apparent plagiarism involving an article in the Annals of Saudi Medicine that ought to receive careful scrutiny.

Neurochemistry journal retracts paper after earlier mega-correction for an author who’s no stranger to errata

The Journal of Neurochemistry has retracted a 2008 paper, “Toll-like receptor 3 contributes to spinal glial activation and tactile allodynia after nerve injury,” it had initially corrected — and how.

The correction, which appeared online in August 2010, was extensive: Continue reading Neurochemistry journal retracts paper after earlier mega-correction for an author who’s no stranger to errata

Controversial homosexuality “reparative therapy” paper staying put despite author’s regrets

We’ve been watching with interest an unfolding flap about a controversial 2003 paper in the Archives of Sexual Behavior (ASB) by a prominent mental health researcher, Robert Spitzer, which suggested that gays could be deprogrammed by so-called “reparative therapy” to change their sexual orientation.

Spitzer, who was instrumental in the effort to extradite homosexuality from the realm of mental illnesses, apparently had developed serious doubts about the validity of his paper, which has been cited 47 times, according to Thomson Scientific’s Web of Knowledge. His regrets came to light recently in a piece by Gabriel Arana, of The American Prospect, detailing his own unfortunate experience with “ex-gay” therapy. In his article, Arana says Spitzer requested that he

Group investigated by University of Louisville corrects lung cancer paper after retracting six others

A group of researchers whose work has been under investigation at the University of Louisville has issued a correction for a paper in the American Journal of Respiratory Cell and Molecular Biology (AJRCMB).

The correction follows three retractions each in the Journal of Biological Chemistry and the AJRCMB, the latter of which made it clear that lab member ShouWei Han was responsible for the manipulations and duplications that brought down the papers. Here’s the new notice, which appeared in the March 1, 2012 issue of the journal: Continue reading Group investigated by University of Louisville corrects lung cancer paper after retracting six others

193 papers could be retracted: Journal consortium issues ultimatum in Fujii case

A group of editors representing nearly two dozen medical journals has issued an ultimatum of sorts to officials at seven Japanese institutions that once employed Yoshitaka Fujii: Validate the papers of the disgraced anesthesiologist or they will be retracted.

Fujii, as we have reported, was fired by Toho University in late February, putatively for failing to obtain ethics approval for a handful of his studies. That much may be true, but the integrity of his data has been in question for more than a decade. At the time of his dismissal, journal editors expressed concern that the university would not pursue an inquiry into Fujii’s data.

Last month, the journal Anaesthesia published a statistical analysis of Fujii’s research bya UK anesthesiologist named John Carlisle which cast serious doubt on the veracity of the studies.

The joint letter forces the question. Continue reading 193 papers could be retracted: Journal consortium issues ultimatum in Fujii case

It’s all bad, it’s all good: JCI retracts for made-up data but authors stand behind work

The Journal of Clinical Investigation has retracted a 2010 article after the researchers acknowledged that the paper contained a substantial amount of manipulated or manufactured data.

How much bad data? Enough to sink seven figures. And the authors said they could not produce raw data in another 19 or so figures and four tables.

But, as the notice states, the researcher said that despite the retraction, they stand by the thrust of their article, “Sphingosine-1-phosphate receptor-2 deficiency leads to inhibition of macrophage proinflammatory activities and atherosclerosis in apoE-deficient mice:” Continue reading It’s all bad, it’s all good: JCI retracts for made-up data but authors stand behind work

Endocrinologist Shigeaki Kato resigns amidst University of Tokyo misconduct investigation

Shigeaki Kato

Shigeaki Kato, an endocrinology researcher at the University of Tokyo who retracted a paper late last month, has resigned amidst an investigation into whether he committed misconduct, Japanese media outlets are reporting.

According to the reports, the university has been investigating Shigeaki Kato and his group, affiliated with the Institute of Molecular and Cellular Biosciences, for scientific misconduct. The investigation was prompted by an outside whistleblower’s allegations in January about 24 of Kato’s papers. The whistleblower claimed that the papers manipulated and reused data improperly, and created a YouTube video to spread the word, as ScienceInsider reported earlier this year.

One of the 24 papers, Continue reading Endocrinologist Shigeaki Kato resigns amidst University of Tokyo misconduct investigation
