Severe asthma (SA), chronic rhinosinusitis with nasal polyps (CRSwNP), and eosinophilic granulomatosis with polyangiitis (EGPA) are three conditions driven by IL-5 and eosinophilic inflammation. As these conditions have high use of healthcare services, as well as lifestyle and psychological burdens, well-tolerated treatment to achieve optimal control is key.

Setting the scene, Bakris defined CKD as a reduction in kidney function (estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m2), alongside the presence of albuminuria (≥30 mg/day) as an indication of kidney damage.

Chemotherapy-induced neutropenia is a frequent, severe, adverse haematological complication of myelosuppressive and immunosuppressive cytotoxic chemotherapy treatment.

An estimated 65 million people worldwide have moderate or severe chronic obstructive pulmonary disease (COPD), an umbrella term used to describe a group of progressive lung diseases that obstruct airflow such as emphysema and chronic bronchitis. Smoking contributes to an estimated 90% of COPD cases, as the harmful chemicals produced during tobacco combustion damage the lungs and airways. Although smoking cessation is the only intervention shown to improve COPD prognosis in smokers, many patients who try to quit continue to smoke.

Metabolic acidosis is characterised by a primary decrease in the serum bicarbonate concentration, a secondary decrease in the arterial partial pressure of CO­2, and a reduction in blood pH. Metabolic acidosis, acute or chronic, may have deleterious effects on cellular function and cause increased morbidity and mortality.

Measurement of fluid biomarkers of neurodegeneration is an emerging approach offering improved diagnostic accuracy of neuropsychiatric conditions, particularly for atypical presentations. This article reports a case where the diagnosis of delirium with dementia was revised based on biomarker analysis, enabling treatment of a primary mood disorder with resolution of recurrent disabling psychiatric symptoms.
