Russian doctor (Sergey Maximishin) who treated Navalny after poisoning has died. Hospital did not mention a cause of death.

Is it odd that I can find very little information about "Dr. Sergey Maximishin" but plenty of info on just "Sergey Maximishin". Doctor was 55 and this guy was born in 1964. Are they the same person?
