The COLO-COHORT (Colorectal Cancer Cohort) study: Protocol for a multi-centre, observational research study and development of a consent-for-contact research platform.

Aim: The COLO-COHORT study aims to produce a multi-factorial risk prediction model for colorectal neoplasia that can be used to target colonoscopy to those at greatest risk of colorectal neoplasia, ensuring that people are not investigated unnecessarily and maximizing the use of limited endoscopy resources. The study will also explore the link between neoplasia and the human gut microbiome. Additionally, the study aims to generate a cohort of colonoscopy patients who are 'research ready' through the development of a consent-for-contact (C4C) platform, to facilitate a range of colorectal cancer prevention studies to be conducted at scale and speed.

Systematic review and meta-analysis: Associations between metabolic syndrome and colorectal neoplasia outcomes.

Aim: Metabolic syndrome (MetS) is a cluster of factors including obesity, hypertension, diabetes, hypercholesterolemia and hyperlipidaemia. It has been associated with an increased risk of colorectal neoplasia. This systematic review and meta-analysis assessed the association between MetS and (i) recurrence of adenomas or occurrence of CRC in patients with prior adenomas, and (ii) survival in patients with CRC.

Uncovering undiagnosed liver disease: prevalence and opportunity for intervention in a population attending colonoscopy.

Objective: Due to high rates of obesity and alcohol consumption, the prevalence of fatty liver disease is increasing. There is no widely adopted approach to proactively screen for liver disease in the community. We aimed to assess the burden of potentially undiagnosed liver disease in individuals attending for colonoscopy to develop a pathway to identify and manage individuals with undiagnosed liver disease.

The value of physical examination in the era of telemedicine.

Telemedicine use has expanded rapidly to cope with increasing demand on services by delivering remote clinical review and monitoring of long-term conditions. Triaging individual patients to determine their suitability for telephone, video or face-to-face consultations is necessary. This is crucial in the context of COVID-19 to ensure doctor-patient safety.

A risk-stratified approach to colorectal cancer prevention and diagnosis.

Population screening and endoscopic surveillance are used widely to prevent the development of and death from colorectal cancer (CRC). However, CRC remains a major cause of cancer mortality and the increasing burden of endoscopic investigations threatens to overwhelm some health services. This Perspective describes the rationale for and approach to improved risk stratification and decision-making for CRC prevention and diagnosis.

Panenteric capsule endoscopy identifies proximal small bowel disease guiding upstaging and treatment intensification in Crohn's disease: A European multicentre observational cohort study.

Background: Endoscopically defined mucosal healing in Crohn's disease is associated with improved outcomes. Panenteric capsule endoscopy enables a single non-invasive assessment of small and large bowel mucosal inflammation.

Aims And Methods: This multicentre observational study of patients with suspected and established Crohn's disease examined the feasibility, safety and impact on patient outcomes of panenteric capsule endoscopy in routine clinical practice.

British society of gastroenterology Endoscopy Quality Improvement Programme (EQIP): overview and progress.

High quality gastrointestinal (GI) endoscopy improves patient care. Raising standards in endoscopy improves diagnostic accuracy, management of pathology and ultimately improves outcomes. Historical identification of significant variation in colonoscopy quality led to the development of the Joint Advisory Group (JAG) on GI Endoscopy, the Global Rating Scale (GRS), JAG Endoscopy Training System (JETS) training and certification.

The NHS Bowel Cancer Screening Program: current perspectives on strategies for improvement.

Colorectal cancer (CRC) is the third most common cancer in the UK. The English National Health Service (NHS) Bowel Cancer Screening Program (BCSP) was introduced in 2006 to improve CRC mortality by earlier detection of CRC. It is now offered to patients aged 60-74 years and involves a home-based guaiac fecal occult blood test (gFOBt) biennially, and if positive, patients are offered a colonoscopy.

The National Oesophagogastric Cancer Awareness Campaign: a locality outcome analysis from County Durham.

Introduction: Oesophageal and gastric cancer is common. Despite advances in investigation and treatment, the outcomes from these cancers remain poor. As part of the Be Clear On Cancer Campaign, the Department of Health runs the National Oesophagogastric Cancer Campaign each year, with key messages of (1) 'Having heartburn most days, for 3 weeks or more could be a sign of cancer' and (2) 'if food is sticking when you swallow, tell your doctor'.

Oesophageal candidiasis and squamous cell cancer in patients with gain-of-function STAT1 gene mutation.

Background: Oesophageal candidiasis is a common, usually self-limiting opportunistic infection, but long-term infection with is known to predispose to oral and oesophageal squamous cell cancer (SCC). Permissive factors that lead to immune deficiencies can underlie persistent or recurring candidiasis, called chronic mucocutaneous candidiasis (CMC). Secondary immune deficiencies are most often due to human immunodeficiency virus (HIV) infection, antibiotic use and immunosuppressive treatment (steroids, chemotherapy).
