A randomized controlled trial of CBT-I and PAP for obstructive sleep apnea and comorbid insomnia : main outcomes from the MATRICS study

Study Objectives -- To investigate treatment models using cognitive behavioral therapy for insomnia (CBT-I) and positive airway pressure (PAP) for people with obstructive sleep apnea (OSA) and comorbid insomnia. Methods -- 121 adults with OSA and comorbid insomnia were randomized to receive CBT-I followed by PAP, CBT-I concurrent with PAP, or PAP only. PAP was delivered following standard clinical procedures for in-lab titration and home setup and CBT-I was delivered in four individual sessions. The primary outcome measure was PAP adherence across the first 90 days, with regular PAP use (≥4 h on ≥70% of nights during a 30-day period) serving as the clinical endpoint. The secondary outcome measures were the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) with good sleeper (PSQI 7) serving as the clinical endpoints. Results -- No significant differences were found between the concomitant treatment arms and PAP only on PAP adherence measures, including the percentage of participants who met the clinical endpoint. Compared to PAP alone, the concomitant treatment arms reported a significantly greater reduction from baseline on the ISI (p = .0009) and had a greater percentage of participants who were good sleepers (p = .044) and remitters (p = .008). No significant differences were found between the sequential and concurrent treatment models on any outcome measure. Conclusions -- The findings from this study indicate that combining CBT-I with PAP is superior to PAP alone on insomnia outcomes but does not significantly improve adherence to PAP

Daytime sleepiness and circadian rhythm disturbance due to pineal and pontine damage.

INTRODUCTION TO THE CASE: Pontine damage and resulting reticular activating system (RAS) dysregulation can cause hypersomnia while pineal damage can lead to disturbed sleep wake cycles. This case demonstrates both features. [...

The Persistent Gender Bias in the Diagnosis of Obstructive Sleep Apnea

Prevalence estimates of obstructive sleep apnea (OSA) continue to rise, partially due to better recognition of and screening for the disease, in part due to increase in obesity and in part due to changes in definitions of obstructive hypopneas. Despite increasing knowledge of the deleterious impact of OSA on health, underrecognition continues to be a major concern, especially in women. A middle-aged man that snores and is sleepy has been the accepted “textbook” picture of OSA; women may present with more atypical symptoms and excessive sleepiness that are not reflected on sleepiness scale questionnaires. Even when presenting with snoring and sleepiness, and in the presence of comorbidities, women are less likely to be evaluated for OSA. Symptom burden and poor health outcomes have been documented in women with OSA and treatment improves their health. In this article, we explore possible causes for this underrecognition of OSA in women, including gender bias and healthcare inequity, and propose solutions

Treatment of chronic insomnia disorder in menopause: evaluation of literature

Objective: Insomnia both as a symptom and as part of chronic insomnia disorder is quite common in menopause. Comorbid conditions, such as restless legs syndrome and obstructive sleep apnea, occur with high prevalence among perimenopausal women with insomnia. Insomnia in this population group is associated with adverse health outcomes, and there are no clear standards on how to treat it.Methods: Based on extensive literature search, 76 articles were identified. Two authors independently graded evidence according to the Oxford Centre for Evidence-Based Medicine Levels of Evidence.Results: Evaluation and treatment of other comorbid sleep disorders are recommended, as is cognitive-behavioral therapy for insomnia. Hormone therapy, eszopiclone, escitalopram, gabapentin, isoflavones, valerian, exercise, and hypnosis are suggested. Zolpidem, quiteiapine XL, citalopram, mirtazapine followed by long-acting melatonin, ramelteon, Pycnogenol, Phyto-Female Complex, yoga, and massage may be considered. Kampo formulas are not recommended. Acupuncture may not be suggested, and cognitive-behavioral therapy that is not tailored for insomnia probably should not be considered.Conclusions: Although a variety of interventions are shown to be helpful in improving sleep in menopause, there is a need for well-designed head-to-head trials with uniform outcome measures.Teva PharmaceuticalsNorthwestern Univ Feinberg Sch Med, Dept Neurol, Chicago, IL 60611 USAUniversidade Federal de São Paulo, Dept Psychobiol, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Gynecol, São Paulo, BrazilSUNY Buffalo, Sch Med, Dept Neurol, Buffalo, NY 14260 USAUniv Kentucky Coll Med, Dept Med, Lexington, KY USAUniversidade Federal de São Paulo, Dept Psychobiol, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Gynecol, São Paulo, BrazilWeb of Scienc

Managing Sleep Disorders during Pregnancy

Sleep disturbances and disorders are common during pregnancy, and they can be risk factors for a number of serious pregnancy-related sleep disorders. These include postpartum depression, pregnancy-induced hypertension, gestational diabetes, and intrauterine growth retardation. In addition, certain chronic sleep disorders, such as narcolepsy, are quite challenging to manage in the context of pregnancy and during lactation, particularly with medications that can be teratogenic. This review discusses 4 common sleep disorders and their impacts on pregnancy, and suggests ways to deal with these disorders that improves maternal and fetal outcomes safely. The review discusses diagnosis and treatment of obstructive sleep apnea, restless legs syndrome, insomnia, and narcolepsy in pregnancy

Improving Sleep Health Among Refugees: A Systematic Review.

PURPOSE OF REVIEW: Sleep disorders among refugees are common yet understudied. Interventions are difficult in resource-limited settings where most of these populations live. A systematic review of sleep disorders in refugee populations is warranted to identify prevalence, comorbidities, and the limitations of the current state of sleep health among refugees. RECENT FINDINGS: Sleep disturbances, particularly insomnia and nightmares, occur with a higher prevalence among refugees. Diseases associated with insomnia in this population included fibromyalgia, posttraumatic stress disorder, depression, and anxiety. Risk factors include trauma, migration, lower socioeconomic status, lower educational level, and settlement in areas with a high influx of new residents or proximity to conflict. Only a few partially successful therapies were identified. SUMMARY: This review identifies the high prevalence of the disturbed sleep in this population and its risk factors. It proposes ways of increasing awareness of it in this vulnerable population as a first step toward remediation

Chronotypes in Patients with Epilepsy: Does the Type of Epilepsy Make a Difference?

Circadian rhythms govern all biological functions. Circadian misalignment has a major impact on health. Late chronotype is a risk factor for circadian misalignment which in turn can affect the control of seizures in epilepsy patients. We compared a group of 87 confirmed epilepsy patients regardless of subtypes with age- and sex-matched healthy controls. We compared generalized epilepsy patients with localization related epilepsy patients and with healthy controls. We found that primary generalized epilepsy patients were 5 times more likely to have a late chronotype than healthy controls. We did not find any significant differences between localization related epilepsy patients and healthy controls or between the overall epilepsy cohort and healthy controls. Generalized epilepsy patients are more likely to be evening types as compared to those with focal epilepsy or subjects without epilepsy. Epilepsy patients do not experience the same age related increase in morningness as do age-matched healthy controls. This is important in regard to timing of AED, identifying and preventing sleep deprivation, and integrating chronotype evaluations and chronotherapy in comprehensive epilepsy care. Further studies, using objective phase markers or the impact of chronotherapy on seizure control, are necessary
