Simulation-Based Learning as a Strategy to Optimizing Efficiency of Upper Endoscopy and Colonoscopy.

Gastrointestinal diseases impose a significant morbidity, mortality, and health care cost burden, affecting millions annually in the United States alone. Endoscopy plays a crucial role in managing these conditions. Despite technological advancements in endoscopy, ensuring efficient, high-quality care remains challenging.

Prospective study on comparison of simulation-based mastery learning versus conventional apprentice-based learning for basic endoscopy training.

Background And Aim: The simulation-based mastery learning (SBML) method holds promise for improving the efficiency and effectiveness of endoscopy training. However, further study is required to establish its advantages over the traditional method. We aim to prospectively compare outcomes between gastrointestinal endoscopy trainees taught using SBML and those trained using conventional apprenticeship methods for upper endoscopy.

A new, widespread genus of Baetidae from South Asia (Insecta, Ephemeroptera).

Material collected on different islands across South Asia revealed a new genus of Baetidae with a widespread distribution, The larvae present important similarities with , but have paraglossae dorsally with an arc of long, spine-like setae in distal area; long, slightly feathered setae between prostheca and mola of both mandibles; and very slender legs with row of short setae at dorsal margin of femur. The male imago has an extraordinarily small 3 (apical) segment of gonostylus, which is much narrower than the apex of the 2 segment. The new genus includes five species: is described from Sumbawa (Indonesia) based on larvae, from Sumatra (Indonesia) based on larvae, from Borneo (Brunei) based on larvae, and (type species) is described from Sri Lanka based on a reared male imago with its larval and subimaginal exuviae; (Chang & Yang, 1994), from Taiwan, formerly described in Margobaetis Kang & Yang, 1994, a subgenus of Baetis Leach, 1815, and subsequently transferred to the genus Kazlauskas (in Novikova & Kluge), 1987, is transferred to the new genus.

The synergistic role of virtual coaching with simulation-based mastery learning for upper endoscopy.

Introduction: Our simulation-based mastery learning (SBML) curriculum, delivered in person, has been shown to successfully train novices in structured esophagogastroduodenoscopy (EGD). SBML with virtual coaching (VC) has the potential to improve the effectiveness and efficiency of endoscopy training and expand access to trainees from around the world. We share our observations conducting an EGD training course using SBML with VC.

Effect of an online educational module incorporating real-time feedback on accuracy of polyp sizing in trainees: a randomized controlled trial.

Background: Although polyp size dictates surveillance intervals, endoscopists often estimate polyp size inaccurately. We hypothesized that an intervention providing didactic instruction and real-time feedback could significantly improve polyp size classification.

Methods: We conducted a multicenter randomized controlled trial to evaluate the impact of different components of an online educational module on polyp sizing.

A method for phenotypic evaluation of grapevine resistance in relation to phenological development.

Fungus-resistant grapevine cultivars, so called PIWIs, are characterized by increased resistance to powdery mildew and downy mildew. However, in order to maintain the durability of resistance in these new grape cultivars, targeted fungicide treatments are recommended. For ideal schedule of these treatments, it is necessary to recognize the most sensitive organs of the grape.

New species of from Southeast Asia (Ephemeroptera, Baetidae).

Based on larvae collected in the Philippines, Borneo (Kalimantan), Sumba, and Sumatra, the presence of the genus in the Philippines and Indonesia is reported for the first time. Six new species are described and illustrated, two from the Philippines and four from Indonesia. A larval key to all species of the Philippines, Indonesia and neighbouring continental Southeast Asia is provided, morphological differences to the species of Taiwan are discussed as well.

Varied Trainee Competence in Cold Snare Polypectomy: Results of the COMPLETE Randomized Controlled Trial.

Introduction: Cold snare polypectomy (CSP) is strongly recommended as the optimal technique for the complete removal of small polyps. Though significant variability in polypectomy technique and quality has been established, the learning curve and impact of targeted training on CSP are unknown. Video feedback has shown promise as an effective pedagogy to improve performance among surgical trainees.

First report of the Afrotropical genus Jacobus, McCafferty & Gattolliat (Ephemeroptera, Baetidae) from Southeast Asia, with description of a new species.

Recent collections in Thailand revealed the occurrence of the genus in Asia, formerly known from the Afrotropical Realm only. A new species of is described and illustrated based on larvae and eggs. Eggs of this genus are described for the first time.

First contribution to Novikova & Kluge in Cambodia (Ephemeroptera, Baetidae), with description of two new species.

Material collected in 2018 in Cambodia gives us first insights into the diversity of Novikova & Kluge, 1987 in this country. No species has been reported so far. We identified two new species using a combination of morphology and genetic distance (COI, Kimura 2-parameter).

A widespread new genus of Baetidae (Baetidae, Ephemeroptera) from Southeast Asia.

A reinvestigation of type and other material of Ulmer, 1913 and Müller-Liebenau, 1984, together with new material from Southeast Asia revealed a new genus, The above species are formally assigned to the new genus It is characterized by the presence of accessory gills ventrally near fore coxa and at the base of maxillae, a peculiar folding of the gonostyli developing under the cuticle of last instar male larvae, together with a unique combination of other larval characters. Besides the two formerly described species, five new species are identified using a combination of morphology and molecular characters (COI, Kimura 2-parameter distances), four species from Sumatra and one from the Philippines. They are described and illustrated at the larval stage.

Two new species of Eaton, 1869 from North Africa (Ephemeroptera, Baetidae).

Two new species are described and illustrated, one from north-eastern Algeria, and one from North Morocco, using an integrated approach with morphological and molecular evidence. A table summarising the morphological differences between the new species and (Müller, 1776) from Central Europe is provided.

Longitudinal outcomes of the endoscopic resection of nonpolypoid dysplastic lesions in patients with inflammatory bowel disease.

Background And Aims: Patients with inflammatory bowel disease (IBD) are at risk of developing dysplasia. According to the Surveillance for Colorectal Endoscopic Neoplasia Detection and Management in Inflammatory Bowel Disease Patients: International Consensus Recommendations, "After complete removal of endoscopically resectable nonpolypoid dysplastic lesions, surveillance colonoscopy is suggested rather than colectomy." We sought to add data to the literature and hypothesized that the endoscopic resection of nonpolypoid colorectal dysplasia (NP-CRD) is safe and effective.

Adenoma Detection Rate and Clinical Characteristics Influence Advanced Neoplasia Risk After Colorectal Polypectomy.

Background And Aims: Postpolypectomy risk stratification for subsequent metachronous advanced neoplasia (MAN) is imprecise and does not account for colonoscopist adenoma detection rate (ADR). Our aim was to assess association of ADR with MAN and create a prediction model for postpolypectomy risk stratification incorporating ADR and other factors.

Methods: We conducted a retrospective cohort study of individuals with baseline polypectomy and subsequent surveillance colonoscopy from 2004 to 2016 within the U.

Baseline Characteristics and Longitudinal Outcomes of Traditional Serrated Adenomas: A Cohort Study.

Background And Aims: Traditional serrated adenomas (TSAs) may confer increased risk for colorectal cancer (CRC). Our objective with this study was to examine clinical characteristics and long-term outcomes associated with TSA diagnosis.

Methods: We conducted a retrospective cohort study of U.

Individualized feedback on colonoscopy skills improves group colonoscopy quality in providers with lower adenoma detection rates.

Colonoscopy inspection quality (CIQ) assesses skills (fold examination, cleaning, and luminal distension) during inspection for polyps and correlates with adenoma detection rate (ADR) and serrated detection rate (SDR). We aimed to determine whether providing individualized CIQ feedback with instructional videos improves quality metrics performance. We prospectively studied 16 colonoscopists who already received semiannual benchmarked reports of quality metrics (ADR, SDR, and withdrawal time [WT]).
