Clinicians working across locum, portfolio and unfamiliar settings get a systems-focused update on portable decision support, flexible workforce platforms and audio learning. It links local prescribing and escalation systems, cognitive load, recorded CPD, scope of practice and recovery planning to safer flexible work.

Emergency, prehospital and critical-care clinicians get a physiology-first review of drowning as water aspiration with hypoxia as the central threat. Early oxygenation and ventilation, severity-based observation, ICU escalation, precipitating illness, trauma and prevention are the practical anchors.

Post-travel diarrhoea is usually clinical, not laboratory-led. This review separates mild self-limiting illness from moderate, severe, bloody or persistent symptoms, with clear attention to hydration, loperamide limits, selective azithromycin use, resistance, and protozoal causes after return.

Difficult treatment conversations need more than asking whether there are questions. Identify the choice, check understanding, ask how involved the patient wants to be and decide who else should join the conversation, especially when culture, capacity or family support affects care.

Clue first: unexplained hypoxaemia or cardiopulmonary deterioration should reopen the PE pathway before anyone clicks straight to CTPA. This is the most immediately useful listen today because it gives a clean route through Wells or Geneva scoring, selective D-dimer use, imaging choice, and early anticoagulation decisions.
