Comparative evaluation of a language model and human specialists in the application of European guidelines for the management of inflammatory bowel diseases and malignancies.

Background: Society guidelines on colorectal dysplasia screening, surveillance, and endoscopic management in inflammatory bowel disease (IBD) are complex, and physician adherence to them is suboptimal. We aimed to evaluate the use of ChatGPT, a large language model, in generating accurate guideline-based recommendations for colorectal dysplasia screening, surveillance, and endoscopic management in IBD in line with European Crohn's and Colitis Organization (ECCO) guidelines.

Methods: 30 clinical scenarios in the form of free text were prepared and presented to three separate sessions of ChatGPT and to eight gastroenterologists (four IBD specialists and four non-IBD gastroenterologists).

Colorectal Cancer Screening in the Elderly: Does Increased Prevalence Necessitate Tighter Surveillance.

Background: With age, colorectal cancer (CRC) prevalence rises. The elderly (> 75 years), and the very elderly (> 85 years) are especially vulnerable. The advantages of screening must be assessed in the context of diminished life span and co-morbidities.

Effect of Doctor's and Assisting Nurse's Years of Experience on Polyp Detection Rate: A Retrospective Cohort.

Background: Polyp detection rate (PDR) is a convenient quality measure indicator. Many factors influence PDR, including the patient's background, age, referral (ambulatory or hospitalized), and bowel cleansing.

Objectives: To evaluate whether years of professional experience have any effect on PDR.

Anti-TNFα Treatment Impairs Long-Term Immune Responses to COVID-19 mRNA Vaccine in Patients with Inflammatory Bowel Diseases.

Patients with inflammatory bowel disease (IBD) treated with anti-tumor-necrosis factor-alpha (TNFα) exhibited lower serologic responses one-month following the second dose of the COVID-19 BNT162b2 vaccine compared to those not treated with anti-TNFα (non-anti-TNFα) or to healthy controls (HCs). We comprehensively analyzed long-term humoral responses, including anti-spike (S) antibodies, serum inhibition, neutralization, cross-reactivity and circulating B cell six months post BNT162b2, in patients with IBD stratified by therapy compared to HCs. Subjects enrolled in a prospective, controlled, multi-center Israeli study received two BNT162b2 doses.
