The past century has witnessed accelerated development in imaging modalities. Better anatomical visualisation and improved data analysis have improved survival rates. Through emerging functional, molecular and structural imaging modalities, better anatomical visualisation has been extended to cellular and molecular detail, improving diagnosis and management of diseases. This article reviews the advances made in emerging imaging modalities as well as their potential applications in targeted therapy.

Idiopathic pulmonary fibrosis (IPF) is a devastating condition with a poor prognosis and few treatment options. However, recent research into this condition has led to considerable insights into the pathophysiology of the disease, resulting in the identification of potential biomarkers to aid diagnosis and stratification of patients and the development of novel therapies. In this review we will discuss the recent developments in this field and review how this knowledge has been translated into clinical trials and a paradigm shift in our approach to patients with IPF.

Kidney transplants do not last for the natural lifespan of most recipients. Of the reasons why transplants fail, damage by the immune system is the commonest cause. Understanding how the immune system recognises transplanted organs has increased significantly in recent years, but there is little insight into how organs are damaged, and no still no way of suppressing immune-mediated damage without exposing patients to the detrimental effects of long-term immunosuppression. In this article, we review the role of antibodies and B cells in immune-mediated damage of kidney transplants, and discuss the potential for manipulation of B cells to improve clinical outcomes.

Perioperative β-blocker therapy has been advocated to reduce cardiac mortality and morbidity in high-risk cardiac patients undergoing non-cardiac surgery. Core data that supported this intervention and informed international societal guidelines has recently been withdrawn. A subsequent meta-analysis of the remaining data reporting excess mortality has re-opened the debate about the utility of β-blocker therapy in the perioperative period. Criticism of remaining trial designs and new insights into the protective mechanisms of β-blocker therapy in critical illness raise important questions that should now be addressed by a further robust, high-quality randomised control trial.
