Relevant to nephrology, acute medicine and ward teams managing severe hypertension, breathlessness or fluid overload in haemodialysis. It prioritises interdialytic blood pressure, dry-weight reassessment, sodium and fluid balance, while showing how medication dialysability should influence drug selection and timing.

Relevant to acute medicine, nephrology and ward teams reviewing haemodialysis patients with shortness of breath, severe hypertension, pulmonary oedema or cramps. It separates solute clearance from ultrafiltration and keeps dry weight, sodium intake, residual urine output and dialysis timing in view.

New atrial fibrillation after surgery is not just a rate problem. Confirm stability, symptoms and exertional limits, then look for pulmonary embolism, bleeding, infection, thyroid disease or electrolyte disturbance before deciding on cardioversion, anticoagulation, monitoring or discharge.

An in-flight seizure or hypoxia leaves limited equipment, patchy monitoring and a diversion decision. The practical move is early ground medical support, clear ABCs, a gathered kit station and deliberate use of nurses, paramedics or other clinicians on board.

Open this first if an abnormal blood test is easy to park. The episode makes eosinophilia a threshold-based problem: use the absolute count, screen for organ damage above 1,500 cells/µL, and think carefully before steroids when Strongyloides or malignancy remains plausible.

Palpitations after coffee are common, but this listen is really about not overreading nutrition headlines. It explains why prospective cohorts still matter, what CRAVE found on premature atrial and ventricular contractions, sleep, and activity, and why coffee advice should follow symptoms, sleep, and comorbidity.

A small plantar ulcer can hide tracking, bone involvement, or poor perfusion. Open this early if foot infections are easy to underestimate: it sharpens probe-to-bone assessment, plain radiographs first, MRI limits, and the practical point that source control and offloading matter as much as antibiotics.

Passing urine does not exclude obstructive AKI. Early kidneyand bladder POCUS can uncover retention or bilateral hydronephrosis, while VExUS, lung ultrasound, and fistula Doppler help decide whether worsening creatinine reflects residual congestion, dry-weight error, or urgent dialysis access planning.

Dementia conversations work best when you start with what the patient understands and how much detail they want. Function often matters more than a score: missed medicines, lost independence and caregiver strain should shape deprescribing, safety planning and follow-up.
