British Society of Gastroenterology National Evaluation of Colonoscopy Quality: Findings from the National Endoscopy Database.

Background And Aims: Analysis of national colonoscopy quality using automatically uploaded data from a national database, including exploring performance variation.

Methods: Data on all colonoscopies performed in the UK 01/03/2019-29/02/2020 and recorded in the National Endoscopy Database were analysed. Unadjusted key performance indicators were calculated and proportions of endoscopists achieving national standards were determined.

Multimodal cell-free DNA whole-genome TAPS is sensitive and reveals specific cancer signals.

The analysis of circulating tumour DNA (ctDNA) through minimally invasive liquid biopsies is promising for early multi-cancer detection and monitoring minimal residual disease. Most existing methods focus on targeted deep sequencing, but few integrate multiple data modalities. Here, we develop a methodology for ctDNA detection using deep (80x) whole-genome TET-Assisted Pyridine Borane Sequencing (TAPS), a less destructive approach than bisulphite sequencing, which permits the simultaneous analysis of genomic and methylomic data.

COLOFIT: Development and Internal-External Validation of Models Using Age, Sex, Faecal Immunochemical and Blood Tests to Optimise Diagnosis of Colorectal Cancer in Symptomatic Patients.

Background: Colorectal cancer (CRC) is the third most common cancer in the United Kingdom and the second largest cause of cancer death.

Aim: To develop and validate a model using available information at the time of faecal immunochemical testing (FIT) in primary care to improve selection of symptomatic patients for CRC investigations.

Methods: We included all adults (≥ 18 years) referred to Nottingham University Hospitals NHS Trust between 2018 and 2022 with symptoms of suspected CRC who had a FIT.

Exploring the policy implementation of a holistic approach to cancer investigation in non-specific symptom pathways in England: An ethnographic study.

Objectives: This study aimed to explore the policy implementation of non-specific symptom pathways within the English National Health Service.

Methods: A multi-site ethnographic project was conducted in four hospitals that contained non-specific symptom pathways between November 2021 and February 2023. The research involved observation (44 h), interviews ( = 54), patient shadowing, and document review.

Hypersensitive intercellular responses of endometrial stromal cells drive invasion in Endometriosis.

Endometriosis is a debilitating disease affecting 190 million women worldwide and the greatest single contributor to infertility. The most broadly accepted etiology is that uterine endometrial cells retrogradely enter the peritoneum during menses, implant and form invasive lesions in a process analogous to cancer metastasis. However, over 90% of women suffer retrograde menstruation, but only 10% develop endometriosis, and debate continues as to whether the underlying defect is endometrial or peritoneal.
