Last year Israeli GM Lev Psakhis was in terrible health, in need of a liver transplant. Psakhis, for those of you who weren't around in the 1980s, twice won the USSR Championship (and back to back!), once tying for first with Garry Kasparov, whom he defeated in their individual game. He was considered a tremendous talent, and while he never lived up to the promise of those early results he has had a successful career since then as a player, author and trainer.
Nevertheless, the battle last year was for his life, and at the moment, having received the needed liver transplant, he seems to be doing well, all things considered. There's an interview with him (in Russian) that you might check out (through Google Translate if need be; maybe Chess in Translation will help out?), in which he discusses his health and offers a few words about the upcoming Anand-Gelfand match, Hou Yifan and some other topics too.
