This paper provides an overview of the INGENIOUS (UnderstandING the sourcEs, traNsformations and fates of IndOor air pollUtantS) project, aiming to better understand air pollution in homes. Although our homes are the microenvironment in which we spend most of our time, we know relatively little about the sources, transformation processes and fates of indoor air pollutants, or our exposure to them. INGENIOUS aims to address this knowledge gap by delivering: an indoor emissions inventory for UK homes; comprehensive air pollutant measurements in 310 homes in Bradford using a combination of low cost-sensors and more advanced air quality instrumentation; an analysis of the impact of indoor air pollution on outdoor air quality and using mobile measurements; insight into future indoor air quality using detailed air pollution models; identification of indoor air pollutants that warrant further toxicological study; and better understanding of the barriers and facilitators for behaviour that drives improved indoor air quality.

Objective: Medical error is an inevitable part of modern healthcare, with a potential harmful impact for the patient and the surgeon. The phenomenon of negative personal responses for healthcare workers in the aftermath of adverse events is described as the "second casualty" and can involve significant physical and psychological distress. We present results from a cross-sectional survey of surgeons and their experience in the aftermath of adverse events or complications.

Purpose: Buccal mucosal grafts have a well-established role in urology regarding the management of ureteric stricture disease. Despite its established use as a graft material there is a lack of data on the mechanical properties of buccal mucosa. We aim to compare the passive mechanical properties of porcine buccal mucosa with the ureter.

Article Synopsis
  • - Fibrodysplasia ossificans progressiva (FOP) is a rare condition that causes painful heterotopic ossification in connective tissues, leading to disability.
  • - In the LUMINA-1 phase 2 trial, adults with FOP were given either garetosmab (an activin A-blocking antibody) or a placebo over two 28-week periods, focusing on safety and effects on HO lesions.
  • - Although the primary efficacy endpoint was not met in the first period, garetosmab significantly reduced the development of new HO lesions in the second period compared to placebo, with ongoing investigations into its effectiveness.

To explore beliefs and practice patterns of urologists regarding intrarenal pressure (IRP) during ureteroscopy (URS). A customized questionnaire was designed in a 4-step iterative process incorporating a systematic review of the literature and critical analysis of topics/questions by six endourologists. The 19-item questionnaire interrogated perceptions, practice patterns, and key areas of uncertainty regarding ureteroscopic IRP, and was disseminated via urologic societies, networks, and social media to the international urologic community.
