Sakura probably didn't suffer lasting effects because whatever part of her that was erased by Madara's TSB, she literally grew new cells from non-erased cells with Strength of a Hundred. As for Edo Sage Minato, that's a more complex issue. There is a possible explanation, but it requires assumptions. Sure, Minato was in Sage Mode when it happened, but the thing is, Edo Tensei itself wasn't senjutsu. Kimimaro felt Orochimaru's chakra flowing through him after being Edoed. That means that it's the summoner's chakra that dictates the summon's stay and regeneration. So if Edo itself wasn't executed with senjutsu chakra, the summons regeneration can be negated by YYR. If not that, then I call plot hole.
