The universally accepted best practice protocol for monitoring patients who receive intravenous thrombolysis for acute ischaemic stroke was established in the 1990s. However, the protocol is burdensome for nurses, disrupts the sleep of patients, and is potentially less relevant in patients at low risk of symptomatic intracerebral haemorrhage. We aimed to assess whether implementing a low-intensity monitoring protocol would be as safe and effective as standard high-intensity monitoring for patients with acute ischaemic stroke at low risk.

It is not known which supplemental imaging technique is most beneficial for women with dense breasts attending breast screening. This study compares abbreviated MRI, automated whole breast ultrasound (ABUS), and contrast-enhanced mammography versus standard of care in women with dense breasts and a negative mammogram. We report on interim results from the first round of supplemental imaging.

ACURATE neo2 is an open-cell, supra-annular, self-expanding transcatheter heart valve that is commercially available in over 50 countries but has not previously been evaluated in a randomised trial. ACURATE-IDE aimed to prospectively evaluate the safety and efficacy of transcatheter aortic valve replacement (TAVR) with the ACURATE neo2 valve compared with commercially available valves for the treatment of severe symptomatic aortic stenosis.

The Lancet Commission on diagnostics made recommendations for ten topics: national strategy (including national essential diagnostics lists), access in primary care, workforce, regulatory framework, national financing, affordability, appropriate use of technology, needs in conflict or fragile situations, advocacy, and an international alliance with oversight capabilities. Since 2021, progress in these areas has benefitted greatly from the adoption of a World Health Assembly resolution on diagnostics and the work of a broad coalition, as assessed by literature surveys by subject matter experts, quantitative findings (where feasible), and an anonymous survey of knowledgeable and engaged individuals. Greater progress was observed where there was political will and the production of diagnostics coincided with industrial policy goals, also in areas where changing the legal and health policy frameworks was involved. Progress was slower on recommendations with substantial resource implications (eg, labour force, affordability, and diagnostics for conflict situations). It is expected that the Global Diagnostics Coalition will consolidate and accelerate progress.
