Study Objectives: Mandibular advancement devices (MAD) constitute a feasible option for management of mild-to-moderate obstructive sleep apnea (OSA) and in severe cases, when indicated. As a chronic condition, the management of OSA with MAD requires long-term patient adherence to treatment. The aim of the study was to investigate adherence to MAD therapy during a 36-month observation period in relation to changes in self-reported symptoms and objective response to therapy.

Methods: Retrospective chart review of patients referred to the Orofacial Pain Clinic (University of Kentucky) between 2016 and 2021 for management of OSA with MAD was performed. Based on a posttreatment sleep study with MAD in situ, participants were subdivided into (> 50% reduction of baseline apnea-hypopnea index) and (< 50% reduction of baseline apnea-hypopnea index) groups. Outcomes included self-reported adherence to MAD use, self-reported OSA symptoms including snoring, apneic episodes, tiredness upon awakening, fatigue, and sleep quality (on a 100-mm numerical rating scale), and daytime sleepiness (0-24 on the Epworth Sleepiness Scale). Intragroup and intergroup differences at different time points over a 36-month observation period were assessed with one-way and repeated-measures analysis of variance.

Results: Of 54 participants included (46.3% female, age 64.4 ± 10.71 years), 30 (55.6%) achieved and 24 (44.4%) achieved At baseline, participants with differed from those with in apnea-hypopnea index ( = .007), snoring ( = .026), and sleep quality ( = .042). Although fluctuating in both groups, no difference was found over time in adherence (7 nights/wk, 7 h/night) and in OSA symptoms (all > .05).

Conclusions: Adherence to MAD was maintained over 36 months regardless of fluctuation in self-reported OSA symptoms and effectiveness of MAD therapy.

The risk of believing that emotions are bad and uncontrollable: association with orthorexia nervosa.

Eat Weight Disord

January 2025

Faculty of Science and Technology, Department of Psychology, Bournemouth University, Poole, UK.

Purpose: This study aimed to explore emotional functioning in individuals with varying levels of orthorexia nervosa (ON) symptoms. Given the established links between emotion dysregulation and other eating disorders (EDs), and the conceptualization of ON within the ED spectrum, this research sought to examine the relationships between ON symptomatology and emotion regulation strategies, alexithymia, and beliefs about emotions.

Methods: A large sample (N = 562) completed self-report measures with high psychometric properties, assessing ON traits (E-DOS), emotion regulation strategies (DERS-SF and ERQ), alexithymia (TAS-20), and beliefs about emotions (ERQ).
