Objective This study explored and compared stakeholder perspectives on enhancements to cervical cancer screening for vulnerable women across seven European countries.Design In a series of Collaborative User Boards, stakeholders were invited to collaborate on identifying facilitators to improve cervical cancer screening.Setting This study was part of the CBIG-SCREEN project which is funded by the European Union and targets disparities in cervical cancer screening for vulnerable women (www.cbig-screen.eu). Data collection took place in Bulgaria, Denmark, Estonia, France, Italy, Portugal and Romania.Participants Represented stakeholders at various levels, including user representatives (vulnerable women), healthcare professionals, social workers, programme managers and decision makers.Methods 14 meetings lasting 2 hours each were held in these seven countries between October 2021 and June 2022. The meetings were audio or video recorded, transcribed and translated into English for qualitative framework analysis.Results We engaged 120 participants in the Collaborative User Boards. Proposed solutions targeted both provider and system levels. In all countries, fostering trusting relationships between vulnerable women and social or healthcare professionals, coupled with community outreach for awareness and access to testing was a consistent recommendation. Participants in Estonia, Denmark, France, Italy, Portugal and Romania advocated for tailoring healthcare services to meet the unique needs of vulnerable populations through a holistic approach. In Bulgaria and Romania, participants advocated for the need to secure free access, from screening to follow-up, and emphasised the need for organised screening with target population screening registries.Conclusion The study offers insights into stakeholders' recommendations for enhancing cervical cancer screening services for vulnerable women across seven European countries. Despite variations in the implementation level of population-based screening programmes, the imperative to optimise outreach and proximity work to improve cervical cancer screening resonated across all countries.

Objectives The aim of this study was to map and compare stakeholders’ perceptions of barriers towards cervical cancer screening for vulnerable women in seven European countries.Design In Collaborative User Boards, stakeholders were invited to participate to identify barriers towards participation in cervical cancer screening.Setting The study is nested in the European Union-funded project CBIG-SCREEN which aims to tackle inequity in cervical cancer screening for vulnerable women (www.cbig-screen.eu). Data collection took place in Bulgaria, Denmark, Estonia, France, Italy, Portugal and Romania.Participants Participants represented micro-level stakeholders covering representatives of users, that is, vulnerable women, meso-level stakeholders covering healthcare professionals and social workers, and macro-level stakeholders covering programme managers and decision-makers.Methods Across the seven countries, 25 meetings in Collaborative User Boards with a duration of 2 hours took place between October 2021 and June 2022. The meetings were video recorded or audio recorded, transcribed and translated into English for a qualitative framework analysis.Results 120 participants took part in the Collaborative User Boards. Context-specific barriers were related to different healthcare systems and characteristics of vulnerable populations. In Romania and Bulgaria, the lack of a continuous screening effort and lack of ways to identify eligible women were identified as barriers for all women rather than being specific for women in vulnerable situations. The participants in Denmark, Estonia, France, Italy and Portugal identified providers’ lack of cultural and social sensitivity towards vulnerable women as barriers. In all countries, vulnerable women’s fear, shame and lack of priority to preventive healthcare were identified as psychological barriers.Conclusion The study provides an overview of stakeholders’ perceived barriers towards vulnerable women’s cervical cancer screening participation in seven European countries. The organisation of healthcare systems and the maturity of screening programmes differ between countries, while vulnerable women’s psychological barriers had several similarities.

While there is convincing evidence on the role of Aire-positive medullary thymic epithelial cells (mTEC) in the induction of central tolerance, the nature and function of post-Aire mTECs and Hassall’s corpuscles have remained enigmatic. Here we summarize the existing data on these late stages of mTEC differentiation with special focus on their potential to contribute to central tolerance induction by triggering the unique pro-inflammatory microenvironment in the thymus. In order to complement the existing evidence that has been obtained from mouse models, we performed proteomic analysis on microdissected samples from human thymic medullary areas at different differentiation stages. The analysis confirms that at the post-Aire stages, the mTECs lose their nuclei but maintain machinery required for translation and exocytosis and also upregulate proteins specific to keratinocyte differentiation and cornification. In addition, at the late stages of differentiation, the human mTECs display a distinct pro-inflammatory signature, including upregulation of the potent endogenous TLR4 agonist S100A8/S100A9. Collectively, the study suggests a novel mechanism by which the post-Aire mTECs and Hassall’s corpuscles contribute to the thymic microenvironment with potential cues on the induction of central tolerance.
