Clinical evaluation of a novel single-use therapeutic gastroscope: a pilot feasibility study.

Background: The trend toward disposable products in gastrointestinal endoscopy, including single-use endoscopes, remains undeterred, even though crucial questions of sustainability and performance have not been sufficiently studied. The first single-use therapeutic gastroscope was recently approved in Europe, but clinical data to support its use are currently lacking. We aimed to evaluate the performance of this novel device in routine procedures requiring a large working channel.

The Ross Operation in Young Patients—a Single-Center, Long-Term Follow-Up Study.

Background: The standard aortic valve replacement operations in young patients are bioprosthetic or mechanical aortic valve replacement. In this study, we present the long-term results of the Ross operation in young patients.

Methods: The Ross operation with root replacement was performed on 795 patients between 1995 and 2020.

Navigating the learning landscape: Comprehensive training in third space endoscopy - training, techniques, and practical recommendations.

Third space endoscopy (TSE), including ESD, POEM, or STER are advanced procedures requiring precise endoscopic control and tissue recognition. Despite its increasing adoption, evidence-based curricula, and standardized training protocols for TSE are lacking. This review explores training methods, cognitive skills, and technical proficiency requirements for endoscopists performing TSE, with a primary emphasis on POEM.

Tofacitinib in Pediatric Ulcerative Colitis: A Retrospective Multicenter Experience.

Background: Tofacitinib has recently been approved for treatment of moderate-to-severe ulcerative colitis (UC) in adults, yet pediatric data are limited. This international multicenter study describes the effectiveness and safety of tofacitinib in pediatric UC.

Methods: This is a retrospective review of children diagnosed with UC treated with tofacitinib from 16 pediatric centers internationally.

Predicting recreational water quality and public health safety in urban estuaries using Bayesian Networks.

To support the reactivation of urban rivers and estuaries for bathing while ensuring public safety, it is critical to have access to real-time information on microbial water quality and associated health risks. Predictive modelling can provide this information, though challenges concerning the optimal size of training data, model transferability, and communication of uncertainty still need attention. Further, urban estuaries undergo distinctive hydrological variations requiring tailored modelling approaches.
