Hypercalcaemia is a common metabolic abnormality and its differential diagnosis is vast. Immobility is an uncommon cause of hypercalcaemia. Immobilisation hypercalcaemia is independent of parathyroid hormone and is associated with low levels of 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D. ⋯ Although immobilisation hypercalcaemia is a diagnosis of exclusion, physicians need to be aware of this condition to avoid excessive and invasive investigations when all other causes of parathyroid hormone-independent hypercalcaemia have been excluded. Management of immobilisation hypercalcaemia revolves around early mobilisation and rehabilitation together with pharmacotherapeutic agents such as intravenous isotonic saline, calcitonin and bisphosphonates. Denosumab may be a potential alternative yet off-label treatment for immobility hypercalcaemia in patients with renal insufficiency.

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.

Anaesthetists might prefer two lungs for ventilation, but this is not always possible. One lung ventilation requires a good knowledge of physiology, anatomy and equipment. This article gives an overview of the basics.
