Background: Although the existing psychometric literature provides guidance on the best method for acquiring a reliable clinical evaluation form (CEF)-based score, it also shows that a single CEF rating has very low reliability.

Purpose: This study examines whether experience with rating students might act as a form of rater training and hence improve the quality of CEF ratings.

Methods: Preceptors were divided into two groups based on rater experience. The univariate and multivariate G study designs used were simple rater (r)-nested-within-person (p) [r : p and r(○) : p(•)] models, and in the univariate analysis was applied separately to CEFs completed by high and low experienced raters.

Results: The high experienced rater group yielded a substantially higher observed reliability in both the univariate and multivariate analyses.

Conclusions: These results support the hypothesis that high experienced raters produce more reliable ratings of student performance and suggest methods for improving CEF ratings.

Background: Identification of predictive biomarkers is crucial for formulating preventive interventions and halting the progression of atopic march. Although controversial, the use of accessible markers to predict or detect early onset of atopic diseases is highly desirable. Therefore, this study aimed to investigate whether corneal squamous cell carcinoma antigen-1 (SCCA1) collected from infants can predict the development of atopic dermatitis and food allergy.

Aim: This study aimed to investigate the relationship between PET and CT parameters and sarcopenia, adipose tissue, and tumor metabolism in esophageal carcinoma(EC) and its impact on survival in EC.

Method: Our study included 122 EC patients who underwent PET/CT for staging. Muscle and adipose tissue characteristics were evaluated, including lumbar(L3) and cervical(C3) muscle areas, psoas major(PM) and sternocleidomastoid muscle(SCM) parameters, and PET parameters for visceral and subcutaneous adipose tissue(SAT).

Objectives: The COVID-19 epidemic introduced significant systems- and disease-based uncertainty into Abdominal Aortic Aneurysm (AAA) rupture management. The goal of this work was to evaluate whether short-term AAA rupture outcomes during COVID-19 were comparable to pre-COVID era outcomes and to explore the impact of COVID status and COVID era healthcare systems restrictions on AAA rupture outcomes.

Methods: The Vascular Quality Initiative (VQI) database was queried for all ruptured AAAs that underwent intervention from January 1, 2019 to August 31, 2022.

Superiority of Linear-Array EUS over MRCP in Diagnosing Pancreas Divisum: Evidence from a Multicenter Retrospective Study in Oriental Cohorts.

Gastrointest Endosc

December 2024

Department of Gastroenterology, Shanghai General Hospital, Shanghai Jiaotong University School of Medicine, Shanghai, China; Shanghai Key Laboratory of Pancreatic Diseases, Shanghai General Hospital, Shanghai Jiao Tong University, Shanghai, China. Electronic address:

Background And Aims: Pancreas divisum (PD) is the most common developmental anatomic variant of pancreatic duct. The published data on the accuracy of the detection of pancreas divisum by linear-array endoscopic ultrasound (L-EUS) is limited. The current study aimed to assess the diagnostic accuracy of L-EUS compared with magnetic resonance cholangiopancreatography (MRCP) for identifying PD.
