Puzzling: Maybe weight loss surgery paper by author who acknowledged fraud is being retracted after all

We’ve been following the case of Edward Shang, a weight loss surgeon who has acknowledged making up most — if not all — of the patients in a now-retracted study in Surgery for Obesity and Related Diseases. Last week, we reported that Obesity Surgery, where Shang had published four papers, would not be retracting any of them. That’s what Surgery for Obesity and Related Diseases Obesity Surgery editor Scott Shikora told us in an email exchange (more on that below).

It turns out, however, that one of Shang’s Obesity Surgery papers had already been retracted, unbeknownst to us because the original abstract was not — and is still not — linked to the retraction notice, which reads: Continue reading Puzzling: Maybe weight loss surgery paper by author who acknowledged fraud is being retracted after all

Obesity Surgery won’t retract papers by weight loss surgeon who published fake data elsewhere

Earlier this week, we reported on the case of Edward Shang, a weight loss surgeon who was forced to retract a study after it became clear that he had enrolled only about a third as many patients as he claimed — if he enrolled any at all. In that post, the editor in chief of Surgery for Obesity and Related Diseases, who retracted the paper, told us he had flagged the issue for Obesity Surgery editors, who had also published Shang’s work.

Yesterday, we heard back from the editor of Obesity Surgery, Scott Shikora, who tells us that he’s reviewed Shang’s four publications in his journal: Continue reading Obesity Surgery won’t retract papers by weight loss surgeon who published fake data elsewhere

Author retracts weight loss surgery paper after admitting most, if not all, of the subjects were made up

If you had read “Aerobic endurance training improves weight loss, body composition, and co-morbidities in patients after laparoscopic Roux-en-Y gastric bypass,” a 2010 paper in Surgery for Obesity and Related Diseases, you might have been convinced by the title and findings that exercise was a good idea for people who’d had stomach stapling.

After all, the authors had operated on “60 consecutive morbidly obese patients” and then randomized them into “a low-exercise group (aerobic physical exercise 1 time for 1 hr/wk) or a multiple-exercise group (APE 2 times for 1 hr/wk)” so they could collect data on “age, gender, length of hospital stay, operative details, co-morbidities, postoperative complications, initial body weight and height, postoperative weight, and body composition.” When they did that, they found that “The multiple exercise group had a significantly more rapid reduction of body mass index, excess weight loss, and fat mass compared with the low-exercise group.”

Except that at best they had only operated on about a third the number of patients they said they had. Continue reading Author retracts weight loss surgery paper after admitting most, if not all, of the subjects were made up

Journal retracts two Stapel papers, on salesmen and on women who change their names when they marry

The journal Basic and Applied Social Psychology has retracted two articles by Diederik Stapel, the Dutch researcher who has admitted falsifying his data. Stapel was suspended from his post at Tilburg University in September.

Here are the notices, which appear together: Continue reading Journal retracts two Stapel papers, on salesmen and on women who change their names when they marry

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

Protein structure retracted after investigation into “highly improbable features,” journal calls it fraud

In 2010, a group of crystallographers immunologists and allergy researchers at the University of Salzburg published a paper in the Journal of Immunology claiming to have derived the structure of a birch pollen allergen.

That structure, however, caught the attention of Bernhard Rupp, an eminent crystallographer. In January of this year, Rupp submitted a paper to Acta Crystallographica Section F pointing out problems with it, which prompted the editors of the crystallography journal to contact the authors of the original paper a month later. Those authors, it turns out, agreed with Rupp, they write in a response to his paper published in the April 2012 issue of Acta Crystallographica Section F: Continue reading Protein structure retracted after investigation into “highly improbable features,” journal calls it fraud

Three more retractions for resveratrol researcher Dipak Das, in free radical journals

Das, via UConn

The retraction count for Dipak Das, the resveratrol researcher whom the University of Connecticut found to have committed 145 counts of fabrication and falsification of data, has risen to eight with withdrawals by Free Radical Biology & Medicine and Free Radical Research.

The two Free Radical Biology & Medicine retractions, for “Expression of the longevity proteins by both red and white wines and their cardioprotective components, resveratrol, tyrosol, and hydroxytyrosol” (cited 38 times, according to Thomson Scientific’s Web of Knowledge) and “Redox regulation of resveratrol-mediated switching of death signal into survival signal” (cited 32 times), are carefully detailed and read the same way: Continue reading Three more retractions for resveratrol researcher Dipak Das, in free radical journals

Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

The Journal of Agricultural and Food Chemistry has retracted three papers by Dipak Das, the resveratrol researcher found to have committed more than 100 counts of fraud by the University of Connecticut.

Journal editor James Seiber writes: Continue reading Hold the broccoli, garlic, and wine: Three Dipak Das retractions appear in Journal of Agricultural and Food Chemistry

Spanish veterinary researcher under suspicion of creating “ghost” author, fabricating data

The Spanish press has picked up on the story of a prominent veterinary scientist in that country who has been accused of research misconduct.

According to El Pais, the researcher, Jesús Ángel Lemus, whose areas of interest include the effects of toxins on birds, ran into trouble in December when colleagues complained to the Ethics Committee of the Higher Council for Scientific Research about the reproducibility of his results and other problems. That triggered an inquiry by the CSIC into Lemus’ body of work, an investigation that, evidently, could not find a body.
