We determined the impact of a system-wide multicomponent intervention to improve recognition and documentation of cognitive frailty syndromes on hospital administrative coding for delirium. ⋯ A multicomponent intervention increased sensitivity of hospital administrative diagnostic coding for delirium almost six-fold without increasing the false positive diagnosis rate.

Case Reports
Lessons of the month: Pyroglutamic acidosis: long-term paracetamol and a high anion gap.
An 84-year-old woman presented in extremis with confusion and Kussmaul respiration. She had a history of urosepsis, renal impairment and osteoarthrosis. The venous blood gas showed a marked metabolic acidosis with a high anion gap. ⋯ Paracetamol was stopped and fluids administered; she recovered over 7 days and was sent home. The biochemical diagnosis was confirmed by a central laboratory after discharge. This case emphasises the importance of the anion gap in diagnosis, and one important danger of chronic paracetamol administration.

Review
Potential role of endothelial cell surface ectopic redox complexes in COVID-19 disease pathogenesis.
The novel coronavirus infectious disease (COVID-19) has rapidly spread and poses a great challenge to researchers, both in elucidating its pathogenic mechanism and developing effective treatments. It has been recently proposed that COVID-19 is an endothelial disease. ⋯ Consequently, oxidative stress could prime these cells to acquire a pro-thrombotic and pro-inflammatory phenotype, predisposing patients to thromboembolic and vasculitic events and to disseminated intravascular coagulopathy (DIC). This implies a pivotal role played by oxygen in the pathogenetic mechanism of COVID-19 disease, in that its availability would tune the oxidant state and consequent damage.

Cholestatic liver diseases are a challenging spectrum of conditions arising from damage to bile ducts, leading to build-up of bile acids and inflammatory processes that cause injury to cholangiocytes and hepatocytes. Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are the two most common cholestatic disorders. In this review we detail the latest guidelines for the diagnosis and management of patients with these two conditions.
