Ethical considerations during a pioneering surgical procedure: porcine cardiac xenotransplantation.
Preclinical advances in life-sustaining porcine cardiac xenotransplantation from donor pigs to baboons have paved the way for the performance of porcine cardiac xenotransplantation in a human. This procedure was performed with emergency use authorisation granted by the United States Food and Drug Administration under the umbrella of investigational new drug use on compassionate grounds. The patient was denied candidacy for durable mechanical circulatory support and heart transplantation as a result of non-adherence to medical advice. ⋯ This article focuses on some of the ethical conflicts encountered in relation to the use of mechanical circulatory support, pretransplant evaluation, shared decision making during informed consent, infectious disease risk, preclinical and clinical testing, and the role of regulatory bodies during performance of the first human porcine cardiac xenotransplantation. An increase in human trials of xenotransplantation procedures is imminent. Potential ethical conflicts associated with xenotransplantation should be addressed appropriately.

Organising pneumonia was first described in the context of respiratory infection, but over time has become established as its own entity. It is an area of diagnostic complexity because of the non-specific presenting symptoms and signs that can often mimic other respiratory pathology. Multidisciplinary review to correlate clinical, radiological and histopathological features can aid timely and effective diagnosis. This article discusses the epidemiology, aetiology, clinical, radiological and histopathological features, investigation and management of organising pneumonia.

The COVID-19 pandemic challenged the NHS to make rapid adjustments to practice to ensure that patients could continue to access vital treatments while reducing the risk of infection. A roundtable discussion was convened, including professionals from cancer care delivery and those working in patient involvement, to discuss experiences during the pandemic and to offer recommendations for the safe transition and implementation of cancer care in the community setting.

The population of people living with human immunodeficiency virus (HIV) is ageing and has an increasing burden of non-acquired immune deficiency syndrome (AIDS)-related morbidity and mortality, including frailty. Frailty is prevalent at a younger age in this population and is associated with multimorbidity, disability and death. This article examines the key interventions to ameliorate the advancement of frailty in people living with HIV. ⋯ Addressing the social determinants of frailty, such as social isolation and loneliness, are beneficial, but are dependent on local charities and resources. More research is required to assess pharmacological and nutritional interventions in frailty. This requires a greater understanding of the exact pathophysiology of frailty, which remains poorly understood.

This article considers the strong public health response to the COVID-19 pandemic, while recognising that the system must be strengthened moving forwards. It provides an overview of the challenges facing public health today including widening social inequalities, increasingly squeezed health and social care budgets, changes to the public health landscape, and recovery from COVID-19.
