A pharmaceutical researcher has received his tenth retraction. The reason, once again: duplicating his previous work.
Giuseppe Derosa, based at the University of Pavia in Italy, lost a 2011 paper this month after journal editors identified “substantial duplication of an earlier published paper.” According to the notice, the authors failed to cite the previous work and to disclose that the manuscript had been published or was under consideration elsewhere.
Derosa has a habit of reusing clinical trial data in multiple papers. He received his first four retractions in 2015 for publishing the same clinical trial results six times—two of those papers were retracted over the summer and two more several months later. By 2016, a fifth from the bunch was retracted (one of the six still stands). Derosa received another retraction, citing duplication (which we covered here and which was not related to the six clinical trials).
