Authors who lost paper linking fecal transplants to obesity have another retracted

International Journal of ObesityAn obesity journal has retracted a study by authors who previously lost another paper that suggested a link between the fecal microbiome and obesity.

We first came across on the now-retracted paper in the International Journal of Obesity (IJO) in April when we reported on the authors’ other retraction in Diabetes. The 2014 paper had a corrigendum, published the same year, and also for image-related issues.

Paper linking fecal transplants to obesity in rats retracted for faked data

The 2014 paper in Diabetes — which found that rats given fecal transplants from obese mice were more likely to become obese themselves if given a particular diet — was pulled after after an institutional investigation found a co-author guilty of falsifying data underlying one figure and fabricating the data of two others.

Co-author Yassine Sakar — formerly based at the French National Institute of Agronomic Research (INRA) in Paris, France — was found responsible for the misconduct. But an official from the institution said that some responsibility must also be shared by the corresponding author Mihai Covosa, who has since resigned from the institution.
