Test-takers, policymakers, teachers, and institutions are increasingly demanding that testing programs provide more detailed feedback regarding test performance. As a result, there has been a growing interest in the reporting of subscores that potentially provide such detailed feedback. Haberman developed a method based on classical test theory for determining whether a subscore has added value over the total score. Sinharay conducted a detailed study using both real and simulated data and concluded that it is not common for subscores to have added value according to Haberman's criterion. However, Sinharay almost exclusively dealt with data from tests with only dichotomous items. In this article, we show that it is more common for subscores to have added value in tests with polytomous items.

Investigation of the Impact of Motor, Nonmotor, Cognitive, and Psychometric Features on Freezing of Gait in Parkinson's Disease.

There are still debates regarding the pathophysiology of freezing of gait (FOG) in Parkinson's disease (PD). This study aims to investigate the potential contribution of the nonmotor symptoms in the pathophysiology of FOG. This was a cross-sectional observational cohort study where we enrolled all consecutive PD patients who applied to our movement disorders outpatient clinics at Etlik City Hospital, Ankara, Turkey, between January 2024 and August 2024.

The expanding portfolio of targeted therapies for ulcerative colitis (UC) suggests that a more precise approach to defining disease activity will aid clinical decision-making. This prospective study used genome-wide microarrays to characterize gene expression in biopsies from the most inflamed colon segments from patients with UC and analyzed associations between molecular changes and short-term outcomes while on standard-of-care treatment. We analyzed 141 biopsies-128 biopsies from 112 UC patients and 13 biopsies from eight inflammatory bowel disease unclassified (IBDU) patients.

Background: Sarcopenia is a progressive muscle disorder that may lead to mobility disability. No pharmaceutical interventions are currently available, and treatment relies on physical exercise and nutrition. The aim of SARA-INT was to investigate whether BIO101 (20-hydroxyecdysone), an activator of the MAS receptor, is safe and improves muscle function and physical performance of community dwelling older sarcopenic patients.

Objective: Endoscopic classification of ulcerative colitis (UC) shows high interobserver variation. Previous research demonstrated that artificial intelligence (AI) can match the accuracy of central reading in scoring still images. We now extend this assessment to longer colon segments and integrate AI into clinical workflows, evaluating its use for real-time, video-based classification of disease severity, and as a support system for physicians.

Introduction: Whether temporal proximity to parental onset of dementia (PPO) can be used to estimate timing of the preclinical stage of sporadic Alzheimer's disease (AD) remains uncertain.
Methods: We investigated cross-sectionally adults aged > 50 without dementia included in the European Prevention of Alzheimer's Dementia (EPAD) study. PPO was tested as a predictor of quantitative levels of cerebrospinal fluid (CSF) β-amyloid (1-42) (Aβ1-42) in those with a parental history of dementia ( = 688) and of phosphorylated tau (p-tau) and EPAD neuropsychological examination (ENE) subscores in an amyloid positive subgroup ( = 226).
