Having a life partner significantly extends survival for most cancer patients. The label given to the partners of cancer patients may, however, influence the health of not just the patients but their partners. “Caregiver” is an increasingly common label for the partners of patients, but it carries an implicit burden. Referring to partners as “careg...

Background: Testosterone is associated with sexual desire and performance in men, but little is known about cognitive mechanisms underlying this relationship. Even less is known about the influence of estradiol, despite its production from testosterone, and high receptor density in brain regions related to male sexual behavior. Method: We used e...
Article
Objective The concept of ‘patient-centered care’ was touted as a pillar of good clinical practice and endorsed by the US Institute of Medicine in a seminal 2001 publication. We explore the extent to which differing medical specialties have engaged with the concept over the last 20 years and how and why this attention has varied among a sample of me...

Article
Full-text available
For a patient to be effective as a “patient representative” within a health-related organization, work and more than just accepting an honorific title is required. I argue that for a patient to be most effective as a patient representative requires different types of background knowledge and commitment than being a “patient advocate”. Patients need...
