BACKGROUND CONTEXT: - Spinal deformities are commonly associated with poor HRQOL. Several questionnaires (e.g. SRS-24 and SRS-22) have been developed to evaluate HRQOL in these conditions. In adults as well as during growth, the HRQOL is considered one of the most relevant outcomes of both conservative and surgical treatment. Rasch analysis is a powerful statistical technique for developing high quality and valid questionnaires. The SRS-24 and SRS-22 have been evaluated using the Rasch analysis, but showed poor measurement properties...

BACKGROUND: To reduce the incidence of hypoxic brain injuries among newborns a national cardiotocography (CTG) education program was implemented in Denmark. A multiple-choice question test was integrated as part of the program. The aim of this article was to describe and discuss the test development process and to introduce a feasible method for written test development in general. METHODS: The test development was based on the unitary approach to validity. The process involved national consensus on learning objectives, standardized item writing, pilot testing, sensitivity analyses, standard setting and evaluation of psychometric properties using Item Response Theory models...

To assess quality, psychological instruments often include additional scales or validity indices to alert users to the presence of questionable data. Although identified cases are often scrutinized further or removed, it is not fully understood how such cases may affect overall analyses if retained. Using a teacher-report instrument of child behavior, this study examined 5 different validity indices: F-Index, Consistency Index, Response Pattern Index, Rasch Outfit, and Rasch Infit. Results showed that methods largely did not identify similar cases...

The subthalamic nucleus (STN) shapes motor behavior and is important for the initiation and termination of movements. Here we ask whether the STN takes aggregated sensory information into account, in order to exert this function. To this end, local field potentials (LFP) were recorded in eight patients suffering from Parkinson's disease and receiving deep-brain stimulation of the STN bilaterally. Bipolar recordings were obtained postoperatively from the externalized electrode leads. Patients were passively exposed to trains of auditory stimuli containing global deviants, local deviants or combined global/local deviants...

BACKGROUND: Fall incidents are a major problem for patients and healthcare. The "Aachen Fall Prevention App" (AFPA) represents the first mobile Health (mHealth) application (app) empowering older patients (persons 50+ years) to self-assess and monitor their individual fall risk. Self-assessment is based on the "Aachen Fall Prevention Scale," which consists of three steps. First, patients answer ten standardized yes-no questions (positive criterion ≥ 5 "Yes" responses). Second, a ten-second test of free standing without compensatory movement is performed (positive criterion: compensatory movement)...

Emerging infectious diseases (EIDs) are considered a major threat to global health. Most EIDs appear to result from increased contact between wildlife and humans, especially when humans encroach into formerly pristine habitats. Habitat deterioration may also negatively affect the physiology and health of wildlife species, which may eventually lead to a higher susceptibility to infectious agents and/or increased shedding of the pathogens causing EIDs. Bats are known to host viruses closely related to important EIDs...

PURPOSE: Emergent retrieval of airway foreign bodies (AFBs) in children remains a priority skill set for pediatric surgeons. In the setting of low procedural volume, simulation-based education with deliberate practice is essential to ensure trainees reach expected surgical competency. The purposes of this work were to (1) create a realistic rigid bronchoscopy for AFB retrieval simulation model and (2) to evaluate preliminary validity evidence of a novel simulator for the use of training and assessing pediatric surgical trainees' rigid bronchoscopy skills...

Health-related quality of life or health status is significantly impaired in bronchiectasis. There is a paucity of brief, simple-to-use, disease-specific health status measures. The aim of this study was to develop and validate the Bronchiectasis Health Questionnaire (BHQ), a new health status measure that is brief and generates a single overall score.Patients with bronchiectasis were recruited from two outpatient clinics, during a clinically stable stage. The development of the questionnaire followed three phases: item generation and item reduction using Rasch analysis, validation, and repeatability testing...

OBJECTIVE: The Quality of Life after Brain Injury (QOLIBRI), a cross-cultural instrument, has been validated in several languages; however, traditional psychometric approaches have critical limitations. Therefore, we applied the Rasch model for validating the 37-item QOLIBRI scale among a Chinese population with traumatic brain injury. PARTICIPANTS AND SETTING: In total, 587 participants (mean age: 44.2 ± 15.4 years; women, 46.3%) were surveyed in neurosurgery departments at 6 hospitals in Taipei, Taiwan...

We propose that chemically inert polymeric films can enhance van der Waals (vdW) forces in the same way as nanofabrication of biomimetic adhesive materials. For the vdW adhesion of an ethylene-chlorotrifluoroethylene (ECTFE) film on rough metal and dielectric substrates, we present a model that combines microscopic quantum-chemistry simulations of the polymer response functions and the equilibrium monomer--substrate distance with a macroscopic quantum-electrodynamics calculation of the Casimir force between the polymer film and the substrate...
