Introduction: Technology has been a major contributor to recent changes in education, where simulation plays a huge role by providing a unique safe environment, especially with the recent incorporation of immersive virtual reality (VR) training. Cardiopulmonary Resuscitation (CPR) is said to double, even triple survival from cardiac arrest, and hence it is crucial to ensure optimal acquisition and retention of these skills. In this study, we aim to compare a VR CPR teaching program to current teaching methods with content validation of the VR course.

Methods: A randomized single-blinded simulation-based pilot study where 26 participants underwent baseline assessment of their CPR skills using a validated checklist and Laerdal QCPR®. Participants were randomly allocated and underwent their respective courses. This was followed by a final assessment and a questionnaire for content validation, knowledge and confidence. The data was analysed using STATA 16.2 to determine the standardized mean difference using paired and unpaired -test.

Results: Subjective assessment using the checklist showed statistically significant improvement in the overall scores of both groups (traditional group mean improved from 6.92 to 9.61 0.0005, VR group from 6.61 to 8.53 0.0016). However, no statistically significant difference was noted between the final scores in both the subjective and objective assessments. As for the questionnaire, knowledge and confidence seemed to improve equally. Finally, the content validation showed statistically significant improvement in ease of use (mean score 3 to 4.23 - of 0.0144), while for content, positivity of experience, usefulness and appropriateness participants showed similar satisfaction before and after use.

Conclusion: This pilot study suggests that VR teaching could deliver CPR skills in an attractive manner, with no inferiority in acquisition of these skills compared to traditional methods. To corroborate these findings, we suggest a follow-up study with a larger sample size after adding ventilation and Automated External Defibrillator (AED) skills to the VR course with re-examination after 3-6 months to test retention of the skills.

ADataViewer: exploring semantically harmonized Alzheimer's disease cohort datasets.

Authors:
Yasamin Salimi Daniel Domingo-Fernández Carlos Bobis-Álvarez Martin Hofmann-Apitius Colin Birkenbihl

Alzheimers Res Ther 2022 May 21;14(1):69. Epub 2022 May 21.

Department of Bioinformatics, Fraunhofer Institute for Algorithms and Scientific Computing (SCAI), 53754, Sankt Augustin, Germany.

Background: Currently, Alzheimer's disease (AD) cohort datasets are difficult to find and lack across-cohort interoperability, and the actual content of publicly available datasets often only becomes clear to third-party researchers once data access has been granted. These aspects severely hinder the advancement of AD research through emerging data-driven approaches such as machine learning and artificial intelligence and bias current data-driven findings towards the few commonly used, well-explored AD cohorts. To achieve robust and generalizable results, validation across multiple datasets is crucial. Read More

Assessment of Testamentary Capacity in Older Adults: Description and Initial Validation of a Standardized Interview Instrument.

Authors:
Roy C Martin Adam Gerstenecker Katina Hebert Kristen Triebel Daniel Marson

Arch Clin Neuropsychol 2022 May 22. Epub 2022 May 22.

Department of Neurology, University of Alabama at Birmingham, Birmingham, AL 35294, USA.

Objective: Testamentary capacity (TC) is a legal construct, which concerns a person's mental capacity to make or amend a will. Although expert clinicians are frequently asked to assess TC in forensic settings, there are few instruments and little empirical research to inform and guide their assessments. The present study describes the development and psychometric properties of a standardized assessment measure of TC (Testamentary Capacity Instrument-TCI), and investigates its reliability and validity.
