With an increased level of awareness of sleep disorders among the public, there has been an increase in requests for sleep studies, and consequently, more referrals made to sleep specialists by primary care physicians and other health care providers. Understanding technical and clinical information provided in the sleep study report is crucial. It offers significant insight in to sleep pathophysiology in relation to patient symptoms. The purpose of this article is to provide a simple and easy method to interpret the reported results of polysomnography for primary care physicians. This will facilitate better understanding and management of patients with sleep disorders and related complications.
Sleep-disordered breathing is a common disorder with a range of harmful sequelae. Obesity is a strong causal factor for sleep-disordered breathing, and because of the ongoing obesity epidemic, previous estimates of sleep-disordered breathing prevalence require updating. We estimated the prevalence of sleep-disordered breathing in the United States for the periods of 1988–1994 and 2007–2010 using data from the Wisconsin Sleep Cohort Study, an ongoing community-based study that was established in ...
601 Validation of the Insomnia Severity Index—Morin et al the initial screening and formal evaluation of insomnia. The patient’s perspective is also of critical importance to monitor progress and evaluate outcome after initiating treatment. From a regulatory perspective, patient-reported outcomes are becoming increasingly used to substantiate evidence of treatment effectiveness in clinical trials. There is a need for assessment tools that are brief, practical, and psychometrically sound both for...

The aim of the study was to explore the clinical significance of periodic leg movements during sleep (PLMS) in rapid eye movement sleep behavior disorder (RBD) and the pathological relation between these two disorders. Eighty-one consecutive idiopathic RBD (iRBD) patients, classified into two groups—27 patients with PLMS (iRBD–PLMS) and 54 patients without PLMS (iRBD w/o PLMS), and 31 patients with idiopathic PLMS (iPLMS)—were enrolled in this study. Descriptive variables including Epworth Sleep...
introduction: Obstructive sleep apnea (OSA) is widely accepted to improve during slow wave sleep (SWS) compared to lighter stages of NREM sleep. However, supporting data to establish the magnitude and prevalence of this effect is lacking. Consequently, we examined this phenomenon, controlling for posture, in a large group of patients investigated for OSA at an academic clinical sleep service. Methods: A detailed retrospective analysis was conducted on data obtained from each 30-sec epoch of slee...

Summary Obstructive sleep apnoea (OSA) is a common disorder in which repetitive apnoeas expose the cardiovascular system to cycles of hypoxia, exaggerated negative intrathoracic pressure, and arousals. These noxious stimuli can, in turn, depress myocardial contractility, activate the sympathetic nervous system, raise blood pressure, heart rate, and myocardial wall stress, depress parasympathetic activity, provoke oxidative stress and systemic inflammation, activate platelets, and impair vascular...

: Several conditions commonly seen in the primary care setting are known to be associated with obstructive sleep apnea (OSA), including hypertension, obesity, coronary artery disease, and type 2 diabetes, and should alert the physician to the possibility of this sleep disorder. The pathophysiology of OSA increases the risk of ischemic heart disease, decreases cardiac function, and elevates the risk of stroke. Treatment of OSA along with appropriate therapy for associated comorbidities presents a...
Study Objectives: The present study examined the first-night effect during the sleep-onset period using the 9 electroencephalogram stage scoring system. Design: After a week of monitoring sleep-wake habits with sleep diaries and wrist actigraphy, polysomnography recording was made for 3 consecutive nights. Setting: Participants slept in their own private, individual, temperature-controlled bedroom in a sleep laboratory at the university. Participants: Eleven healthy student volunteers (5 women a...

Abstract null null Context null : Cancer patients often experience cancer-related fatigue (CRF) and sleep disturbances due to cancer and cancer treatment, and symptoms can persist long after treatment. Despite these common occurrences, few studies simultaneously characterize CRF and sleep architecture among cancer patients. null null null Objectives null : The objective was to characterize CRF and the sleep architecture of patients seen in a CRF clinic and sleep clinic at the University of Texas...

Background Acupuncture is an alternative treatment for improving sleep, and it may attenuate oxidative stress, which is a possible pathophysiological factor in insomnia. The aim of this study was to examine the efficacy and safety of a semi-individualized acupuncture in improving sleep and explore its effect on oxidative stress parameters in adults with insomnia disorder. Methods In this randomized sham-controlled trial, 140 participants were randomly assigned to either a 4-week semi-individuali...
OBJECTIVES To evaluate the self-reported incidence of sleep disturbances, defined as ≤7 hours of sleep per 24-hour period, in patients undergoing arthroscopic-assisted knee surgery. METHODS Patients who underwent arthroscopic knee surgery over the course of a 4-month period were prospectively included. Patients were excluded if a history of insomnia or other sleep altering medical history was reported. Self-reported sleep metrics included average number of hours of sleep per night, average numbe...

Social inequities have many health effects; one of these is a potential relationship to sleep disturbances. Socioeconomic status (SES) is an important factor that contributes to social inequities. SES is a marker of living conditions and habits that influence health by way of different processes, including stress-related mechanisms. However, a systematic review of the relationship between SES and objectively measured sleep parameters has not been conducted. Therefore, a systematic review and met...

CONTEXT Omega-3, a long-chain polyunsaturated fatty acid (LC-PUFA), may help promote healthy sleep outcomes. However, evidence from randomized controlled trials are inconclusive. OBJECTIVE The objective of this systematic review and meta-analysis was to explore the impact of omega-3 LC-PUFA supplementation and related dietary intervention in clinical trials as well as omega-3 LC-PUFA exposure in longitudinal studies on human's sleep-related outcome. DATA SOURCES The PubMed, EMBASE, Cochrane Libr...
Latinx college students are at high risk of suffering from depressive symptoms. A factor posited to influence depressive symptoms among Latinx college students is racial/ethnic discrimination. However, the mechanisms which link racial/ethnic discrimination to depressive symptoms are not well understood. This study examined the mediating role of racism-related vigilance and sleep-related factors (i.e., sleep quality, sleep efficiency) on the relationship between perceived intergroup racial/ethnic...
Background Sleep problems have significant negative health consequences on university students. Study aim To assess subjective sleep quality, sleep latency, and sleep duration in a national sample of university students and investigate differences in these components with selected variables. Methods A cross-sectional analysis and multi-stage sampling were conducted to select a sample of 1308 students from three major areas in Jordan. Sleep quality, sleep latency, and sleep duration were measured...
