Changes in field perspective from pre- to post-intervention
A Bayesian repeated measures ANOVA was used for the total number of specific-field memories (across both remoteness conditions) with time (pre-and post-intervention) as a within-subjects factor, and group (LKM, colouring) as the between-subjects factor. An analysis of residuals confirmed the assumptions of linearity. R...

Changes in specificity mediated by changes in self-discrepancies
The current study expected LKM to reduce self-discrepancies thus LKM was expected to impact features of AM retrieval via self-discrepancies. Mediation analyses were therefore performed below. Due to the small sample size for mediation analyses, bootstrapping was used with 5,000 bootstrapping samples and 95.0% confidenc...

Abstract

Background
SKIN
Medical Adhesive Related Skin Injuries can arise from topically applied medical devices, especially in those with fragile skin, including the elderly and premature infants. The purpose of this study was to compare gentleness and reapplication of two pulse oximetry sensors (OxySoftN and MaxN, Medtronic, Boulder, CO).

Materials and methods

Eighteen healthy subjects aged 65 years and older were enrolled in the gentleness trial, and 20 healthy subjects (18–69 years) were enrolled in the reapplication trial. For the gentleness trial, trans‐epidermal water loss (TEWL) measurements were made at five sites on each forearm at three time points (baseline [T0], 4...

The silicone‐based adhesive of the OxySoftN sensor does not appear to disrupt the skin barrier function, as evidenced by the TEWL results.

CONCLUSION
DECAY
Silicone adhesive can be a good solution for strong, yet gentle adhesives that are repositionable. The current study demonstrates that the OxySoftN sensor made of silicone had greater repositionability and less skin removal compared to the traditional MaxN sensor with acrylic and synthetic rubber adhesives.

Rationale
Behavioral economic drug purchase tasks quantify the reinforcing value of a drug (i.e., demand). Although widely used to assess demand, drug expectancies are rarely accounted for and may introduce variability across participants given diverse drug experiences.
PMC10006272
Objectives
Three experiments validated and extended previous hypothetical purchase tasks by using blinded drug dose as a reinforcing stimulus, and determined hypothetical demand for experienced effects while controlling for drug expectancies.
