Over recent decades, the perception of osteoporosis has changed from that of an inevitable consequence of ageing, to that of a well characterised and treatable chronic non-communicable disease, with major impacts on individuals, healthcare systems and societies. Characterisation of its pathophysiology from the hierarchical structure of bone and the role of its cell population, development of effective strategies for the identification of those most appropriate for treatment, and an increasing armamentarium of efficacious pharmacological therapies, have underpinned this evolution. Despite this marked progress, individuals who experience a fragility fracture remain under-treated in many areas of the world, and there is substantial need for investment both in secondary and primary prevention globally. In this brief article, we give an overview of the pathogenesis of osteoporosis, and summarise current and future approaches to its assessment and -treatment.

In this article, we discuss the practical usefulness of selecting future medical students on the basis of increasingly popular non-academic tests (eg multiple mini-interviews, situational judgment tests) in addition to academic tests. Non-academic tests assess skills such as ethical decision making, communication and collaboration skills, or traits such as conscientiousness. ⋯ We provide some numerical examples in the context of medical student selection. Finally, we suggest that optimising training in non-academic skills may be a more successful alternative than selecting students on the basis of these skills.

Cardiovascular disease (CVD) remains one of the commonest sources of morbidity and mortality in the world. Lipids and especially low density lipoprotein cholesterol (LDL-C) contribute to the risk of CVD events. Statins are the primary therapy for hypercholesterolaemia and recent evidence supports the use of ezetimibe as a second-line agent. ⋯ Activating mutations in PCSK9 give rise to a form of familial hypercholesterolaemia, while inactivating mutations lead to lower LDL-C levels and fewer CVD events. Therapies to inhibit PCSK9 are in development and two antibody-based therapies - alirocumab and evolocumab - have recently been licensed. This article reviews the actions of PCSK9, the novel therapeutics targeted on this molecule and how they are likely to be used in clinical practice until large scale CVD outcome studies with PCSK9 inhibitors are published.
