• Paul Wilkinson and Andy Haines call for consequences to the Volkswagen diesel scandal in an editorial.

• Sepideh Saadatmand and colleagues assessed the influence of stage at breast cancer diagnosis, tumour biology, and treatment on survival in contemporary times of better (neo-)adjuvant systemic therapy in a large population based study from the Netherlands.
