Influenza immunization among resident physicians in an urban teaching hospital.

We surveyed resident physicians (RPs) at an academic medical center to determine the rate of influenza vaccination and reasons for nonvaccination. The overall self-reported immunization rate of RPs in 2013-2014 was 76.7%, and the most common reason for not being vaccinated was lack of time to get immunized (38.

Captivity reduces hippocampal volume but not survival of new cells in a food-storing bird.

In many naturalistic studies of the hippocampus wild animals are held in captivity. To test if captivity itself affects hippocampal integrity, adult black-capped chickadees (Poecile atricapilla) were caught in the fall, injected with bromodeoxyuridine to mark neurogenesis, and alternately released to the wild or held in captivity. The wild birds were recaptured after 4-6 weeks and perfused simultaneously with their captive counterparts.
