According to a university release — which was apparently retracted for about an hour and which we’ve had trouble accessing at various points this morning — Shang’s employment contract with the Leipzig hospital is “terminated by mutual agreement with immediate effect.”
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 DiseasesObesity Surgery editor Scott Shikora told us in an email exchange (more on that below).
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.
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.”
