Randomized Controlled Trial
Frequency and predictors of obstructive sleep apnea among individuals with major depressive disorder and insomnia.
Disturbances in sleep continuity are common among individuals with major depressive disorder (MDD) and can impact the course of depression and response to treatment. Several studies have examined depressive symptom severity among sleep-disordered patients with obstructive sleep apnea (OSA). In contrast, little is known about OSA in patients with MDD. The goal of this study was to examine the frequency and predictors of OSA in a sample of individuals with comorbid MDD and insomnia. ⋯ These findings indicate that the frequency of OSA is higher among individuals with comorbid MDD and insomnia than was previously found among people with either MDD or insomnia alone. In addition, previously identified predictors of OSA (male sex, older age, and high BMI) also apply to this population.

Depressive symptoms and anxiety are common in heart failure patients as well as their spousal caregivers. However, it is not known whether their emotional distress contributes to their partner's quality of life (QoL). This study examined the effect of patients' and partners' depressive symptoms and anxiety on QoL in patient-spouse dyads using an innovative dyadic analysis technique, the Actor-Partner Interdependence Model (APIM). ⋯ Interventions to reduce depression and anxiety and to improve patients' QoL should include both patients and spouses.

Alexithymia, a lack of emotional awareness, is common in chronic pain patients. The aim of the study was to investigate the relationship of alexithymia to ongoing pain, experimental pain sensitivity, and illness behavior in patients with chronic musculoskeletal pain. ⋯ Alexithymia is associated with increased affective pain and hypochondriacal illness behavior. The former relationship is better explained, and possibly mediated, by psychological distress and illness behavior. The hypothesis of a generally increased sensitivity to unpleasant stimuli in alexithymic chronic pain patients is not supported by the data.
