Background: Denosumab is a fully human monoclonal antibody that binds to, and inhibits, the receptor activator of RANKL (TNFSF11) and might affect breast cancer biology, as shown by preclinical evidence. We aimed to assess whether denosumab combined with standard-of-care adjuvant or neoadjuvant systemic therapy and locoregional treatments would increase bone metastasis-free survival in women with breast cancer.

Method: In this international, double-blind, randomised, placebo-controlled, phase 3 study (D-CARE), patients were recruited from 389 centres in 39 countries.

Comparison of peer assessment and faculty assessment in an interprofessional simulation-based team training program.

Challenges related to limited clinical sites and shortage of clinical instructors may reduce the quality of clinical experiences, leading to increased demand for the establishment of simulation-based training programs in the curricula of educational institutions. However, simulation-based training programs in health education place great demands on faculty resources. It is interesting, therefore, to investigate peers contributions in formal assessment, and how this compares to faculty assessment.
