Objectives null The gold standard for diagnosing an infection with SARS-CoV-2 is detection of viral RNA by nucleic acid amplification techniques. Test capacities, however, are limited. Therefore, numerous easy-to-use rapid antigen tests based on lateral flow technology have been developed. Manufacturer-reported performance data seem convincing, but real-world data are missing. null Methods null We retrospectively analysed all prospectively collected antigen tests results performed between 23.06....

Abstract null Background and aims null Conventional endoscopic mucosal resection (CEMR) with submucosal injection is the current standard for the resection of large, non-malignant colorectal polyps. We investigated whether underwater endoscopic mucosal resection (UEMR) is superior to CEMR for large (20-40 mm) sessile or flat colorectal polyps. null Methods null In this prospective randomized controlled study, patients with sessile or flat colorectal polyps between 20 and 40 mm in size were rando...

Introduction null Risk stratification in upper gastrointestinal bleeding (UGIB) currently relies on clinical parameters and risk scores. HemoPill® acute (Ovesco Endoscopy, Tuebingen, Germany) is a pill-shaped, orally administered sensor capsule for real-time blood detection. The aim of this study was to evaluate the system in clinical routine. null Material and methods null Sixty-one consecutive patients in whom the HemoPill® had been used at 12 international hospitals between July 2019 and Marc...

Objective Artificial intelligence (AI) may reduce underdiagnosed or overlooked upper GI (UGI) neoplastic and preneoplastic conditions, due to subtle appearance and low disease prevalence. Only disease-specific AI performances have been reported, generating uncertainty on its clinical value. Design We searched PubMed, Embase and Scopus until July 2020, for studies on the diagnostic performance of AI in detection and characterisation of UGI lesions. Primary outcomes were pooled diagnostic accuracy...

PURPOSE: The COVID-19 pandemic has affected healthcare systems worldwide. Data on the impact on otolaryngological clinics and private practices is sparse. This study aimed to present data on healthcare worker (HCW) screening, status of HCW, pre-interventional testing, the use of personal protective equipment (PPE) and the economic impact of the pandemic. METHODS: Otolaryngological private practices and hospital-based departments were surveyed nationwide using an online questionnaire. Participati...

BACKGROUND Despite the worldwide burden of diverticular disease, the connections between diverticular disease and dietary habits remain poorly understood, particularly in an asymptomatic representative sample. We investigated the association between asymptomatic diverticular disease as assessed by magnetic resonance imaging (MRI) and dietary habits in a Western study cohort. METHODS Participants from a cross-sectional sample of a population-based cohort study underwent whole-body 3T-MRI includin...

Patienten mit chronisch-entzundlichen Darmerkrankungen (CED) haben ein erhohtes Risiko fur die Entwicklung von Kolonkarzinomen. Risikofaktoren sind unter anderem die chronisch-persistierende Entzundungsaktivitat und bei der Colitis ulcerosa die Krankheitsausdehnung. Die fruhzeitige Detektion von Dysplasien und Fruhmalignomen ist durch die Etablierung von entsprechenden hochqualitativen Vorsorgeendoskopien, z. B. mit Chromendoskopie, moglich geworden. Durch eine rechtzeitige risikoadaptierte endo...
