WLS Surgeon Faked Data in Medical Studies

From Retraction Watch: Three more retractions for weight loss surgeon Edward Shang for making up data.

Edward Shang, the weight loss surgeon who lost his job at the University of Leipzig in May after it was revealed that he had made up most, if not all, of the patients in his research studies at the University of Mannheim, has retracted three more papers...

The authors of the above articles have requested their withdrawal, notifying the Journal that the clinical trials described in the articles were not conducted as written in the article. The Editor-in-Chief, the American Society for Parenteral and Enteral Nutrition, and the Publisher have determined to retract the articles.

The first paper has been cited three times, according to Thomson Scientific’s Web of Knowledge, while the third one has been cited 32 times.

Shang has already retracted a study in Surgery for Obesity and Related Diseases, and one in Obesity Surgery. A May 9 University of Leipzig press release refers to a total of six retractions, so there is apparently one more on the way.

Here are the three latest studies in question:

  • Pump-assisted versus gravity-controlled enteral nutrition in long-term percutaneous endoscopic gastrostomy patients: a prospective controlled trial. Journal of Parenteral and Enteral Nutrition, 2003;27:216-219.
  • Pump-assisted enteral nutrition can prevent aspiration in bedridden percutaneous endoscopic gastrostomy patients. Journal of Parenteral and Enteral Nutrition 2004;28:180-183.
  • The Influence of early supplementation of parenteral nutrition on quality of life and body composition in patients with advanced cancer. Journal of Parenteral and Enteral Nutrition, 2006;30:222-230.

Is anyone actually surprised and aghast that this guy was faking his results. It seems like over site on studies is so non-existent anymore that when a study is actually true I am surprised.

It's not a lack of oversight that's the problem, IMHO. Scientists aren't toddlers that need a babysitter. It's a lack of ethics. Fat people aren't fully human, so who cares what really happens to us, right? /sarcasm

The peer review process does provide some oversight, but unfortunately, peer reviewers have no way to spot faked data. They're also as susceptible to confirmation bias as anyone else, and that's an issue as well.

I was glad to read that the university fired him.
