Personalised estimation of exposure to ambient air pollution and application in a longitudinal cohort analysis of cognitive function in London-dwelling older adults.

Background: Accurate estimates of personal exposure to ambient air pollution are difficult to obtain and epidemiological studies generally rely on residence-based estimates, averaged spatially and temporally, derived from monitoring networks or models. Few epidemiological studies have compared the associated health effects of personal exposure and residence-based estimates.

Objective: To evaluate the association between exposure to air pollution and cognitive function using exposure estimates taking mobility and location into account.

Clinicians' perspectives on the use of artificial intelligence to triage MRI brain scans.

Artificial intelligence (AI) tools can triage radiology scans to streamline the patient pathway and also relieve clinician workload. Validated AI tools can mitigate the delays in reporting scans by flagging time-sensitive and actionable findings. In this study, we aim to investigate current stakeholder perspectives and identify obstacles to integrating AI in clinical pathways.

What Impact Does Net Zero Action on Road Transport and Building Heating Have on Exposure to UK Air Pollution?

This study explores the cobenefits of reduced nitrogen dioxide (NO), ozone (O), and particulate matter (PM), through net zero (NZ) climate policy in the UK. Two alternative NZ scenarios, the balanced net zero (BNZP) and widespread innovation (WI) pathways, from the UK Climate Change Committee's Sixth Carbon Budget, were examined using a chemical transport model (CTM). Under the UK existing policy, Business as Usual (BAU), reductions in NO and PM were predicted by 2030 due to new vehicle technologies but plateau by 2040.

Impact of Sheath Type on Vascular and Bleeding Complications After Transcatheter Aortic Valve Replacement: A Post Hoc Analysis From the MARVEL Registry Study.

Background: Vascular and bleeding complications remain a concern after transfemoral transcatheter aortic valve replacement (TAVR). The impact of the sheath type on these complications remains unclear.

Methods: The prospective MARVEL registry study analyzed enrolled 500 patients undergoing large-bore transfemoral procedures and arteriotomy closure with the MANTA vascular closure device from 10 hospitals in Europe and Canada.
