AI Article Synopsis

  • - The Inhibitory Retrieval Approach to exposure therapy focuses on how prediction errors, or the discrepancy between expected and actual results, can enhance treatment for fears and anxiety by challenging people’s expectations during exposure.
  • - A study involving adults with social anxiety and spider phobia used ecological momentary assessment (EMA) to track changes in their expectations about feared outcomes for several days after exposure sessions and found that expectancy ratings dropped significantly and stayed stable afterward.
  • - Limitations include a small sample size in this pilot study, which suggests the need for further research to confirm these findings in a larger group.

Article Abstract

Background And Objectives: The Inhibitory Retrieval Approach to exposure therapy for fears and anxiety emphasizes prediction error as one of several strategies for improving outcomes. Prediction error depends on disconfirmation of expectancies for the feared outcome, and thus exposure strategies that derive from inhibitory retrieval approaches emphasize expectancy violation during exposure. However, research studies examining expectancy violation in exposure therapy have treated expectancy as a stable characteristic, assuming that expectancy following an exposure exercise remains constant over time. This brief report outlines two different uses of a methodology for using ecological momentary assessment (EMA) to assess between-session expectancy following exposure during treatment for anxiety, and reports on pilot trial results.

Methods: Adults with social anxiety disorder (N = 12) and spider phobia (N = 31) taking part in larger trials investigating exposure therapy completed EMA questionnaires assessing expectancy for their feared outcome for 2-4 days following each of two exposure sessions.

Results: Expectancy ratings decreased from pre-to post-exposure and remained stable for 2-4 days following exposure.

Limitations: This pilot study used a very limited sample size and should be replicated in a larger sample.

Conclusions: Expectancy for feared outcome may be assessed using EMA following exposure sessions. Pilot results suggest that expectancy decreases immediately following exposures and remains stable afterwards.

Objectives: Concurrent type 1 diabetes (T1D) and celiac disease (CeD) pose challenges in insulin dosage adjustments and gluten-free dietary adherence. Urine testing for gluten immunogenic peptides (GIP) is a new method to detect gluten exposure within the last 3-12 h. Our aims were to compare gluten-free dietary adherence between T1D + CeD and CeD individuals and evaluate urinary GIP testing in an outpatient setting.

This paper investigates individuals' averting behavior that utilizes a durable good, high-functioning air purifiers, to reduce risk from exposure to coarse (PM) and fine (PM) particulate matter, to estimate a value of statistical life (VSL) for use in benefit-cost analysis in South Korea. We present an interactive risk ladder, developed specifically for this study, to 1218 respondents in a national web-based contingent valuation survey to elicit their perceived risks from the exposure to PM and PM with and without the use of high-functioning air purifiers (i.e.

Assessment of atmospheric volatile organic compounds at two crude oil production plants in Southeastern Türkiye.

Environ Monit Assess

December 2024

Graduate School of Natural and Applied Sciences, Gazi University, Ankara, 06500, Türkiye.

Ambient Volatile Organic Compounds (VOCs) were investigated to determine their characteristics, Ozone Formation Potentials (OFPs), and health risks in two crude oil production plants (Nusaybin and Egil plants) in southeastern Türkiye. Benzene, toluene, ethylbenzene, m + p xylene, o xylene, and 1,3,5-trimethylbenzene were measured at eight passive sampling points in each plant. Samples were analyzed using gas chromatography coupled with a flame ionization detector and a thermal desorption.

Gold nanoparticles (GNPs) encapsulated in amphiphilic block copolymers are a promising system for numerous biomedical applications, although critical information on the effects of various preparation variables on the structure and properties of this unique type of nanomaterial is currently missing from the literature. In this research, we synthesized GNPs functionalized with thiol-terminated polycaprolactone (PCL-GNPs) before encapsulating them into poly(ε-caprolactone)--poly(ethylene glycol) (PCL--PEG) micellar nanoparticles via nanoprecipitation to yield GNP-loaded polymeric nanoparticles (GNP-PNPs). We explored the role of different manufacturing variables (water volume, PCL--PEG to PCL-GNP ratio, and PEG block length) on the sizes, morphologies, GNP occupancies, colloidal gold concentrations, and time stability of GNP-PNPs.
