After Torres & Kim are rescued on Ocampa, they are beamed directly to Voyager's sick bay, still wearing the clothes given to them by the Ocampan doctors. But when the scene segues back to Voyager's sick bay, Torres is wearing leather civilian clothes and Kim is wearing a uniform. (These clothes had been removed from them on the Caretaker's array.)
Tuvok includes the Ocampan city's energy surplus that will "last at least five years" in the evidence he lists in support of the hypothesis that the Caretaker is dying. However, that information was revealed to Kim and Torres by the nurse who tells them how to access the surface. Nobody told the away team that information.
When Janeway first enters Engineering to investigate the warp core fracture, a technician tells her the pressure is 2100 KPa; she reacts as though that is dangerously high. Following the procedure to lower the reaction rate (and thus core pressure), the quoted pressure is 2500 KPa -- higher than before.
When the shuttle carrying Tom Paris is first approaching Deep Space Nine and Voyager, the registry number on the shuttle clearly reads "1701-D". The model used for the shuttle is clearly one built for Star Trek: The Next Generation.
