Background: Safe deferral of revascularisation is a key aspect of physiology-guided percutaneous coronary intervention (PCI). While recent evidence gathered in the FAVOR III Europe trial showed that quantitative flow ratio (QFR) guidance did not meet non-inferiority to fractional flow reserve (FFR) guidance, it remains unknown if QFR might have a specific value in revascularisation deferral.
Aims: We aimed to evaluate the safety of coronary revascularisation deferral based on QFR as compared with FFR.
Introduction: Diagnostic work-up of older women with a positive cervical cancer screening test is often challenging due to incomplete visualization of the transformation zone. To reduce the risk of missing disease, a diagnostic cervical excision may be performed. However, little is known on treatment efficacy and post-treatment surveillance for older women.

- Fast radio bursts (FRBs) are intense signals from deep space that last for milliseconds and share some characteristics with pulsars, suggesting they may originate from neutron stars.
- Despite similarities, FRBs like 20221022A display different patterns in their linear polarization position angle (PA), particularly a 130° rotation that aligns with pulsar behaviors, hinting at magnetospheric origins.
- This study rules out short-period pulsars as potential sources for FRB 20221022A, supporting the idea that its unique PA evolution fits the rotating vector model commonly used for pulsars.
Background: Fractional flow reserve (FFR) or non-hyperaemic pressure ratios are recommended to assess functional relevance of intermediate coronary stenosis. Both diagnostic methods require the placement of a pressure wire in the coronary artery during invasive coronary angiography. Quantitative flow ratio (QFR) is an angiography-based computational method for the estimation of FFR that does not require the use of pressure wires.

Objectives: This study aimed to investigate the perspectives of international experts and Danish citizens on relevant knowledge about population-based breast, colorectal and cervical cancer screening.
Methods: This was a qualitative interview study with focus group interviews with experts and Danish citizens eligible for breast, colorectal and/or cervical cancer screening. Data were collected using semi-structured interview guides, audio-recorded and transcribed verbatim.
