Diagnoses of military-relevant sleep disorders have increased substantially since the terrorist attacks of 9-11. The cause of this increase appears to be complicated and multifactorial, with military and civilian populations clearly differing with respect to both the nature and distribution of sleep disorders diagnoses. In part, these differences may be attributable to the fact that a majority of service members (SMs) are chronically sleep restricted - an unavoidable consequence of continuous and sustained military operations that 'set the stage' for development of specific sleep disorders...

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) is a heterogeneous condition covering many clinical phenotypes in terms of the diversity of symptoms. Patient-based OSA screening questionnaires used in routine practice contain significantly varying contents that can impact the reliability and validity of the screening. We investigated to what extent common patient-based OSA screening questionnaires differ or overlap in their item content by conducting a rigorous, methodical, and quantified content overlap analysis...

STUDY OBJECTIVES: The objective of this study is to discern distinguishing characteristics of sleep-related breathing disorders (SRBD) in individuals with chronic spinal cord injury (CSCI) compared to able-bodied participants (non-CSCI). Additionally, the study investigates factors associated with SRBD severity. METHODS: This is a cross-sectional analysis of 123 able-bodied individuals, 40 tetraplegics, and 48 paraplegics, who underwent attended or partially supervised full polysomnography, for suspected SRBD, in a rehabilitation center...

STUDY OBJECTIVES: Night-to-night variability of sleep-disordered breathing (SDB) limits the diagnostic accuracy of a single measurement. Multiple recordings using a reliable, affordable method could reduce the uncertainty and avoid misdiagnosis, which could be possible with radar-based home sleep apnea testing (HSAT). METHODS: We recruited consecutive patients with suspected SDB and performed contactless radar-based HSAT with automated scoring (Sleepiz One) over ten nights...

This case report reviews worsening obstructive sleep apnea (OSA) events in a patient over-titrated with a hypoglossal nerve stimulator (HNS). A healthy 57-year-old man underwent HNS implantation for moderate OSA. During an in- laboratory HNS titration the patient had improvement of his OSA at 2.1V. However further increase of voltage resulted in worsening of obstructive events. The pathophysiology behind this finding is unknown but may result from unfavorable changes in the upper anatomy due to higher energy delivered to the hypoglossal nerve and surrounding structures...

STUDY OBJECTIVES: The first objective was to compare tongue motor skills between patients with obstructive sleep apnea (OSA) and healthy subjects. Secondly, the effect of oropharyngeal myofunctional therapy (MFT) on the tongue muscular qualities of patients with OSA was evaluated. METHODS: Searches were conducted in five electronic databases until July 2023. Risk of bias was assessed via the Joanna Briggs Institute appraisal checklist for cross-sectional studies (aim #1) and the PEDro scale for randomized controlled trials (aim #2)...

STUDY OBJECTIVES: Sleep laboratory polysomnography (PSG) is the gold standard for obstructive sleep apnea (OSA) diagnosis in infants, but its access remains limited. Oximetry-capnography is another simple and widely used tool that can provide information on the presence of desaturations and alveolar hypoventilation. However, its reliability is debated. This study aimed at examining its use in determining OSA severity in infants. METHODS: This retrospective study was conducted in a sleep unit in a tertiary hospital, in infants < 4 months old with clinical signs of OSA or Pierre Robin Sequence (PRS) who underwent a one-night PSG coupled with oximetry-capnography...

STUDY OBJECTIVES: The reduction in daytime sleep during early life is considered one of the indicators of the maturation of sleep patterns, which is closely associated with cognitive development. The current study aims to analyze the relationships between daytime sleep duration (DSD) during infancy and cognitive development at 6 and 10 years. METHODS: The study included 262 mothers with their newborns from the Shanghai Sleep Birth Cohort Study, spanning eleven follow-ups from 42 days to 10 years...

STUDY OBJECTIVES: Narcolepsy type 1 (NT1) is attributed to a deficiency in cerebrospinal fluid orexin and is considered linked to autoimmunity. The levels of anti-Tribbles homolog 2 (TRIB2) autoantibodies are elevated in the sera of some patients with narcolepsy with cataplexy. Additionally, injecting mice with serum immunoglobulin from patients with narcolepsy with positive anti-TRIB2 antibodies can induce hypothalamic neuron loss and alterations in sleep patterns. Consequently, we hypothesized the existence of a potential association between anti-TRIB2 antibodies and narcolepsy...

STUDY OBJECTIVES: To investigate the association between different sleep patterns and inflammatory and oxidative stress biomarkers in adults. METHODS: A total of 321 consented adults who fulfilled the inclusion criteria were recruited in this cross sectional study. The inclusion criteria were mainly based on age of 18-59 years of apparently healthy adults. To identify sleep patterns, participants were requested to wear the actigraphy for one week for 24- hours a day...

STUDY OBJECTIVES: Epilepsy and obstructive sleep apnea syndrome (OSAS) are each relatively common in children. OSAS may affect cognition, such that recognition of OSAS is important for children and young people with epilepsy (CYPWE). Published pilot data reported 55% CYPWE had symptoms suggestive of OSAS, compared with 7% typically developing controls. The primary aim of this study was to ascertain OSAS prevalence by polysomnography (PSG) in CYPWE, with secondary aims being to evaluate the utility of sleep questionnaires in CYPWE...

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) is associated with an increased risk of diabetes-related complications. Hence, it is plausible that Continuous Positive Airway Pressure (CPAP) could have a favorable impact on these complications. To assess the feasibility of conducting a randomized control trial (RCT) in patients with type 2 diabetes (T2D) and OSA over 2 years. METHODS: An open-label multicenter feasibility RCT of CPAP vs no CPAP in patients with T2D and OSA...

STUDY OBJECTIVES: Insomnia with objective short sleep duration (ISSD) has been associated with cardiometabolic outcomes i.e., hypertension or diabetes. We examined whether ISSD, based on objective or subjective sleep measures are associated with more serious health problems such as incident cardiovascular and/or cerebrovascular disease (CBVD). METHODS: 1,258 men and women from the Penn State Adult Cohort (56.9% women, 48.3±12.95 years) without CBVD at baseline were followed up for 9...

Sleep-related painful erection (SRPE) is a parasomnia defined by the repetition of painful erections during REM sleep. Hypnic headache (HH) is a primary headache occurring exclusively at night, often during REM sleep. We report the observation of a 33-year-old man with simultaneous SRPE and HH. Physical examination was normal. Comprehensive urological and endocrine explorations excluded other organic differential diagnoses. Polysomnography revealed several awakenings in REM, due to SRPE and concurrent HH. Medication by baclofen at bedtime seemed to have resulted in a decrease of SRPE episodes, confirmed by polysomnography, but at the cost of excessive daytime sleepiness, and was discontinued by the patient...

STUDY OBJECTIVES: Positive airway pressure (PAP) therapy adherence rates range from 30-60%, yet adherent patients may still express dissatisfaction with treatment. Identification of factors affecting PAP tolerance could provide insight into its impact on adherence. METHODS: Obstructive sleep apnea (OSA) patients presenting for first follow up visit after newly initiating PAP therapy were given a 10-question PAP tolerance survey encompassing domains of psychosocial perception, practical issues, and side effects, utilizing 10-point visual analog scales...
