Published: August 2018

These data provide estimations of test-retest reproducibility of streamline counts based on diffusion weighted imaging (DWI) data using a global tractography algorithm in a sample of young healthy adults. Data on descriptive statistics and factorial analyses of within-session and between-session reproducibility in terms of intra-class correlation coefficients for the absolute agreement between measurements are provided. The effect of several exemplary methodological parameters pertaining to different steps along the tractography processing pipeline on reproducibility are considered. These data are related to the research article entitled 'Probing the reproducibility of quantitative estimates of structural connectivity derived from global tractography' (Schumacher et al., Neuroimage, 175 (2018) 215-229).

Background: Patients with knee osteoarthritis (KOA) often experience persistent pain and functional impairment after total knee arthroplasty (TKA), which presents challenges for pain management. Accurate preoperative assessment of pain characteristics is crucial for tailoring individualized treatment plans. The PainDETECT Questionnaire has been widely used to identify neuropathic components in chronic pain and has been validated for its reliability and validity across various cultural contexts.

Background: Moral intelligence is a significant and influential factor in the delivery of principled and high-quality care. This is because moral intelligence is the ability to recognize and be sensitive to moral issues, which contributes to the organization of appropriate behavior in the face of moral issues. This is particularly pertinent given that pre-hospital emergency medical services personnel (prehospital EMS personnel) frequently encounter stressful and tension-filled situations.

Although it is recognized that periodontal disease negatively impacts quality of life, there is no validated instrument to assess this impact in Brazil. This study aimed to translate, cross-culturally adapt, and validate the OHIP 14 PD (Oral Health Impact Profile Applied to Periodontal Diseases) for application among Brazilian patients. The original instrument was translated and validated into Brazilian Portuguese in a cross-sectional study with 110 participants recruited from a Dental School clinic.

This article presents the development and validation of the Short Phronesis Measure (SPM), a novel tool to assess Aristotelian phronesis (practical wisdom). Across three studies, using large, nationally representative samples from the UK and US (demographically matched to census data), we employed a systematic and rigorous methodology to examine the structure, reliability, and validity of the SPM. In Study 1a, exploratory factor analysis identified ten distinct, internally reliable components of phronesis, challenging the traditional four-component Aristotelian model.
