Randomized Controlled Trial
Impact of a brief dietary self-monitoring intervention on weight change and CPAP adherence in patients with obstructive sleep apnea.
Weight loss can decrease the severity of obstructive sleep apnea (OSA) in many obese individuals; however, very few studies have investigated the effects of behavioral weight loss interventions for patients with OSA. The aims of this pilot study were to determine the feasibility and initial effects on weight and continuous positive airway pressure (CPAP) use of a brief minimal-contact self-monitoring-based weight loss intervention (SM). An additional aim was to investigate the association between weight loss and CPAP adherence. ⋯ This study provides initial support for the beneficial effects of a minimal-contact weight loss intervention for patients with obstructive sleep apnea and highlights a possible association between weight loss and CPAP adherence.

Catastrophizing is an exaggerated negative evaluation and attention to specific symptoms such as pain or fatigue. A number of studies consistently support the significant role of catastrophizing in pain. However, the role of catastrophizing in fatigue is less frequently investigated. This article provides a critical review of published studies investigating this association. ⋯ In spite the differences of its definition and the measurements used, a similar significant association between catastrophizing and fatigue was reported. Because this observation was based on 14 studies with limited types of patients, further studies are recommended to examine the role of catastrophizing in fatigue from other clinical populations and to investigate its utility as a behavioral marker for central fatigue.

Depression and anxiety lead to increased morbidity and mortality in patients with coronary artery disease (CAD). Medication nonadherence is one possible pathway contributing to adverse outcome, but it is unknown how either depression or anxiety itself influences adherence compared to combined depressive-anxious comorbidity. The aim of the study was to evaluate the influence of simultaneous depressive and anxious symptoms on medication adherence in patients with stable CAD. ⋯ Apart from depressive symptoms, anxiety is a second important and independent marker for nonadherence in patients with coronary artery disease. The negative effect of anxiety on medication adherence increases in case of comorbid depressive symptoms. Future studies addressing medication adherence should focus more on anxious-depressive comorbidity than on singular depressive or anxious symptoms.
