Stigma represents a major obstacle in rehabilitation and community reintegration after brain injury. However, appropriate tools to measure stigma in Spanish-speaking countries are lacking. This study examined the psychometric properties of the Spanish version of the Anticipated Stigma and Concealment Questionnaire (ASCQ).

Background And Objectives: To compare the diagnostic performance of an immunoassay for plasma concentrations of phosphorylated tau (p-tau) 217 with visual assessments of fluorine-18 fluorodeoxyglucose [F]FDG-PET in individuals who meet appropriate use criteria for Alzheimer dementia (AD) biomarker assessments.

Methods: We performed a retrospective analysis of individuals with early-onset (age <65 years at onset) and/or atypical dementia (features other than memory at onset), who were evaluated at a tertiary care memory clinic. All participants underwent measurements of CSF biomarkers (Aβ42, p-tau181, and total tau levels), as well as [F]FDG-PET scans, amyloid-PET scans, and plasma p-tau217 quantifications.

Article Synopsis
  • The study aimed to compare the in vitro binding characteristics of three radiotracers ([F]flortaucipir, [F]MK6240, [F]PI2620) in postmortem brain samples from Alzheimer’s disease (AD) and control groups.
  • Significant differences in tracer binding were found in the whole-brain hemisphere, prefrontal cortex, and hippocampus between AD and control tissues, with [F]MK6240 and [F]PI2620 showing better performance in differentiating AD cases.
  • The results indicate that [F]MK6240 and [F]PI2620 have higher selectivity and binding to AD tissues compared to [F]flortaucipir,

Background And Purpose: This study was undertaken to compare the performance of plasma p-tau181 with that of [F]fluorodeoxyglucose (FDG) positron emission tomography (PET) in the identification of early biological Alzheimer disease (AD).

Methods: We included 533 cognitively impaired participants from the Alzheimer's Disease Neuroimaging Initiative. Participants underwent PET scans, biofluid collection, and cognitive tests.

Objectives: The objective of this study was to develop and validate 6 checklists for evaluating abdominal pain in clinical simulation scenarios; to assess student competencies in managing 6 clinical cases using OSCE, based on faculty evaluations; and to analyze discrepancies between faculty and student evaluations.

Design: A practical workshop was designed to address 6 clinical scenarios of abdominal surgical conditions. Four scenarios employed medium fidelity simulators, while 2 scenarios employed standardized patient methodology.
