Background: Psychosocial factors that may affect acceptance of artificial pancreas (AP) systems have been investigated in small sample sizes of highly motivated, self-selected persons with type 1 diabetes (T1DM) with a focus on product characteristics. We aimed to develop a valid survey to investigate the association of technology readiness and social influence with AP acceptance in a larger sample, including both self-selected and invited respondents with T1DM.
Methods: An online survey was developed based on established questionnaires. Intention to use the AP was chosen as measure of AP acceptance. T1DM patients who signed up themselves for scientific research into AP systems represented the self-selected group, while patients treated at a teaching hospital represented the invited group. Questionnaire values were compared using independent -tests and regression analyses.
Results: The developed survey showed reliability and validity. The survey was completed by 425 self-selected and 109 invited persons. Intention to use the AP was high in both groups, but was significantly higher among self-selected respondents. In both groups, intention to use the AP was most strongly related to product compatibility, followed by product complexity, technology readiness, and product usefulness among invited respondents; and followed by product usefulness and technology innovativeness among self-selected respondents.
Conclusions: Product characteristics have a stronger relationship with AP acceptance than technology readiness, while social influence does not seem to be associated with AP acceptance. As the (strength of) factors differ between self-selected and invited persons, researchers and product developers should be cautious when relying on self-selected persons with T1DM in the design, development, and testing of AP systems.

Aim: This study aims to determine and compare the achieved competencies of graduating nursing students of public and private universities in Iran.
Background: The main responsibility of nursing education is to train nurses who possess the necessary competencies to provide safe and high-quality care. Given that a significant proportion of nursing education in Iran is the responsibility of private universities, it is essential to ensure that nursing graduates acquire the required competencies.

To battle seasonal outbreaks of influenza B virus infection, which continue to pose a major threat to world health, new and improved vaccines are urgently needed. In this article, we discuss the current state of next-generation influenza B vaccine development, including both advancements and challenges. This review covers the shortcomings of existing influenza vaccines and stresses the need for more-effective and broadly protective vaccines and more-easily scalable manufacturing processes.

Entrustment can help identify and mitigate the risks of incorporating generative AI tools with limited transparency about their accuracy, source material, and disclosure of bias into HPE practice. With AI's growing role in education-related activities, like automated medical school application screening and feedback quality and content appraisal, there is a critical need for a trust-based approach to ensure these technologies are beneficial and safe.
