My physician sent in my medical results to Cic on the 22nd of January. However, the medical result field has the default comment on it at the moment. This will probably change in a few weeks. 
I have noticed 4 ghost updates on my application, so far. The background check field changed to "we are processing your background check. We will send you a message if we need more information. ", a few days ago. 
Wishing everyone a speedy processing time, cheers!
