Citric acid esters of mono- and diglycerides of fatty acids (E 472c) was re-evaluated in 2020 by the Food Additives and Flavourings Panel (FAF Panel) along with acetic acid, lactic acid, tartaric acid, mono- and diacetyltartaric acid, mixed acetic and tartaric acid esters of mono- and diglycerides of fatty acids (E 472a,b,d,e,f). As a follow-up to this assessment, the FAF Panel was requested to assess the safety of citric acid esters of mono- and diglycerides of fatty acids (E 472c) for its use as food additive in food for infants below 16 weeks of age belonging to food categories (FCs) 13.1.

Crohn's disease (CD) and ulcerative colitis (UC) are chronic relapsing inflammatory bowel disorders (IBD), the pathogenesis of which is uncertain but includes genetic susceptibility factors, immune-mediated tissue injury and environmental influences, most of which appear to act via the gut microbiome. We hypothesized that host-microbe alterations could be used to prognostically stratify patients experiencing relapses up to four years after endoscopy. We therefore examined multiple omics data, including published and new datasets, generated from paired inflamed and non-inflamed mucosal biopsies from 142 patients with IBD (54 CD; 88 UC) and from 34 control (non-diseased) biopsies.

Background: Acid reflux is a common presentation in primary care leading to a high volume of referrals to endoscopy that are often normal.

Aims: To determine whether a non-endoscopic capsule sponge biomarker test could triage patients with low-risk reflux symptoms, reduce endoscopy waiting lists and identify Barrett's oesophagus in a real-world setting.

Methods: Patients with reflux symptoms on NHS endoscopy waiting lists who were offered a capsule sponge (test group) between February 2021 and August 2022 were included in this national multicentre prospective cohort study and compared with eligible patients on the standard endoscopy pathway (counterfactual group).

There has been discussion and confusion about SNOMED-CT (systematised nomenclature of medicine clinical terminology), learning health systems (LHSs) and their relevance in dentistry. This article aims to provide an overview of SNOMED-CT, LHSs and the all-too-often omitted patient and service benefits from their use. LHSs are delivering impactful benefits to patients and services globally in medicine.

CDKN2A is a tumor suppressor located in chromosome 9p21 and frequently lost in Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC). How CDKN2A and other 9p21 gene co-deletions affect EAC evolution remains understudied. We explored the effects of 9p21 loss in EACs and cancer progressor and non-progressor BEs with matched genomic, transcriptomic and clinical data.
