Based on prior studies, trainee and practicing gastroenterologists miss pre-cancerous polyps (adenomas and serrated polyps) during colonoscopy. The use of computer-aided detection (CADe) systems, a form of artificial intelligence (AI) has been shown to help identify colorectal lesions for practicing gastroenterologists. However, less is known how AI impacts polyp detection for trainees. The investigators are conducting a tandem colonoscopy study wherein a portion of the colon is examined first by the trainee and then the attending physician. For each procedure, randomization will occur which will determine whether or not the trainee will utilize AI for their examination of the colon. At the end of the study, the investigators will determine whether AI helps trainees miss fewer polyps during colonoscopy. The investigators will also conduct interviews with trainees to understand how AI impacts colonoscopy training.
This is a parallel, Phase 2, 2-arm, multicenter, randomized, double-blind, placebo-controlled, proof-of-concept study for treatment of CRSwNP. The purpose of this study is to assess the efficacy, safety, and tolerability of add-on therapy with subcutaneous lunsekimig in adult participants (aged 18 to 70 years, inclusive) with CRSwNP who are inadequately controlled on intranasal corticosteroid treatment. Participants with and without co-morbid asthma will be included in the study, and lung function will be assessed in both groups. The study duration will be up to approximately 40 weeks per participant, including 4 weeks of screening run-in period, 24 weeks of intervention period, and 12 weeks of follow-up.
This clinical trial tests a multilevel intervention at the clinic, provider and patient levels, to improve colonoscopy surveillance in patients with high risk colon polyps. Colorectal cancer (CRC) is a common and deadly disease that is largely preventable through the detection and removal of colorectal polyps. One million Americans are diagnosed with high risk polyps of the colon or rectum annually and are at increased risk for CRC; however, uptake of recommended repeat colonoscopy in 3 years to reduce CRC risk is low in this group. This multilevel intervention may work to improve timely colonoscopy screening for patients with high risk colon polyps.
The main purpose of this study is to evaluate the efficacy and safety of lebrikizumab in adult participants with chronic rhinosinusitis and nasal polyps treated with intranasal corticosteroids. The study will last about 18 months.

The findings will help us define the natural history of colon serrated lesions, develop techniques for endoscopic management of patients with serrated lesions, and identity areas for improvement. The data will be used for continuing quality improvement and presenting our outcomes at academic meetings and publishing our results in peer reviewed journals.
With this study, the investigators plan to review the performance of colonoscopic resection of large (\> 1 cm) and flat lesions in the colon. The findings will help us define the role of colonoscopic resection of colon polyps and flat lesions and identity areas for improvement. The data will be used for continuing quality improvement and presenting our outcomes at academic meetings and publishing our results in peer reviewed journals.
This study aims to investigate the impact of various healthy diets, specifically a modified plant-based Mediterranean diet, on the gut microbiome and overall well-being post-colonoscopy. The investigators hypothesize that certain diets can positively influence gut bacteria, reducing inflammation and enhancing metabolic signals. To explore this, they will utilize metagenomic testing on stool samples to analyze the DNA of gut microorganisms. Additionally, they will conduct immune profiling on serum samples and perform metabolomic analysis to comprehensively evaluate the diet-induced changes in immune response and metabolic pathways. This multi-faceted approach will help them understand how dietary changes affect the composition and function of the gut microbiome, immune function, and overall metabolism.
The 'CRS validation project' consists of a joint effort of 32 medical centers in Europe, the USA, and South Africa to carry out the validation of 2 novel questionnaires designated to measure self-perceived severity and control of Chronic Rhinosinusitis (with or without nasal polyps). This study will validate translated versions of the same set of questionnaires simultaneously in the centers involved after recruiting a total of 1000 patients, while data collection, statistical analysis, and creation of the study report will be carried out by the statistical department of the University of Leuven. Patients will be recruited from the regular ENT practice of their hospital to minimize the complexity of the study.
The goal of this randomized clinical trial is to learn if a combination of hot and cold EMR technique is associated with a lower risk of polyp recurrence without increasing the risk of complication when removing large polyps. Participants will undergo EMR and return for a follow-up endoscopy in 3-6 months to check for polyp recurrence.
The goal of this clinical trial is to collect capsule images for the development of CADe software for use with the CapsoCam® Colon (CV-3E) in healthy volunteers who have been referred for colonoscopy. There will be no analysis performed as part of this protocol. Participants will * adhere to bowel prep instructions and dietary requirements * ingest pro-kinetic medication and CapsoCam® Colon (CV-3E) * adhere to booster regimen and dietary requirements until capsule passes * retrieve capsule with retrieval kit per instructions and mail back to sponsor * participate in follow-up phone call
The goal of this observational study is to learn what can predict the return of the sense of smell in patients with chronic rhinosinusitis with nasal polyps being treated with dupilumab. The main questions it aims to answer are: 1. Does obstruction of the olfactory cleft predict return of the sense of smell? 2. Do electrophysiological signals generated by breathing and sniffing behavior predict return of the sense of smell? Participants starting dupilumab will undergo assessment for their degree of olfactory cleft obstruction, and an electrophysiologic assessment of their olfactory cleft and be followed over 6 months of treatment with dupilumab.

Study details include: 1. The study duration will be up to 40 weeks. 2. The treatment duration will be up to 24 weeks. 3. The visit frequency will be once every 4 weeks (Q4W).
Non-inferiority trial comparing the recurrence rate of adenomas in non-pedunculated colonic lesions following endoscopic mucosal resection with margin marking (EMR-MM) and endoscopic mucosal resection with thermal margin ablation (EMR-STSC)
Three-dimensional (3D) printing has been an emerging technology with uses in a wide array of fields. This research aims to use 3D printing as a tool to provide personalized education to maximize treatment efficacy based on the patient's individual anatomy. With increased irrigation to the sinuses, we hypothesize there will be improved patient satisfaction and higher quality of life. The outcomes of this research could lead to a new option for patients who live with chronic rhinosinusitis are not candidates for surgery or are interested in less invasive options. The 3D printed nasal replica is not something that would be implanted, rather it is a hand-held device used specifically for participants to better understand their nasal anatomy.
Beans are a forgotten staple food that shows promise in improving health. The goal of this study is to look at how bean supplementation affects metabolic and bowel health.
