Hello,
It is possible to get newly added pull requests with the added collection:
ctx.issue.pullRequests.added
(see Set for more info)

Also, you can create a local variable and use the switch statement to make the code more compact:

var issue = ctx.issue;
var fs = issue.fields;
switch(issue.pullRequests.added.first().state.name) {
  case "OPEN":
    fs.State = ctx.State.Review;
    break;
  ...
}
