Objectives: Vedolizumab is a mAb used for the treatment of moderate to severe ulcerative colitis and Crohn's disease. There is evidence that administration of vedolizumab has been associated with either new onset or reactivation of extra-intestinal manifestations, among which arthralgia is the most prominent. We aimed to study the incidence, characteristics and predictors for the occurrence of arthralgias in patients with inflammatory bowel disease (IBD) who receive vedolizumab.

METHODS : We developed the POLyp Artificial Recognition (POLAR) system, which was capable of performing real-time characterization of diminutive colorectal polyps. For pretraining, the Microsoft-COCO dataset with over 300 000 nonpolyp object images was used.

- A study was conducted to evaluate how different types of colonoscopes affect the training and quality of colonoscopy procedures, focusing on factors like technical competence and patient comfort.
- The research involved 126 patients divided into three groups based on the type of colonoscope used: adult colonoscope (AC), intermediate pediatric colonoscope (IPC), and long pediatric colonoscope (LPC), measuring outcomes such as examination completeness and patient tolerance.
- Results indicated that the LPC was the most effective in training, achieving higher terminal ileal intubation rates and causing less discomfort, making it the recommended choice for starting colonoscopy training.*
Introduction: Our aim is to develop a novel approach to hyperkinetic movement disorder classification, that combines clinical information, electromyography, accelerometry and video in a computer-aided classification tool. We see this as the next step towards rapid and accurate phenotype classification, the cornerstone of both the diagnostic and treatment process.
Methods And Analysis: The Next Move in Movement Disorders (NEMO) study is a cross-sectional study at Expertise Centre Movement Disorders Groningen, University Medical Centre Groningen.
Article Synopsis
- Hyperplastic polyps are common findings during colonoscopy and generally have a low risk of cancer, but guidelines suggest that most polyps should be removed, with exceptions for certain small ones.
- A unique case involved the discovery of a duodenal-type follicular lymphoma in a 5 mm polyp that looked hyperplastic, which later spread to the stomach and duodenum after four months.
- The case highlights the need for caution in optical diagnosis and the use of a "resect and discard" strategy, as this situation has not been previously documented in medical literature.
Background: Misdiagnosed sessile serrated lesions (SSLs) are important precursors for interval colorectal cancers.
Aims: We investigated the usage of acetic acid (AA) solution for improving the detection of SSLs in the right colon in a randomized controlled trial.
Methods: A tandem observation of the right colon was performed in 412 consecutive patients.
Aim: To evaluate the uptake of screening colonoscopy among physicians as compared to the general population.
Methods: Asymptomatic physicians, aged 45-67 years, at average risk for colorectal cancer (CRC), working in the participating National Health System hospitals were asked to complete a questionnaire regarding the uptake of screening colonoscopy. The results were compared to those in a background healthy population, aged 50-75 years, inhabitants of a Greek county, who were offered a free access to a screening colonoscopy program for CRC.
Background/purpose: Visual characteristics such as color and shape of skin lesions play an important role in the diagnostic process. In this contribution, we quantify the discriminative power of such attributes using an information theoretical approach.
Methods: We estimate the probability of occurrence of each attribute as a function of the skin diseases.
