Abstract Objectives To determine whether a change in clinical management (e.g., new tracheostomy or adenotonsillectomy) occurred following a polysomnogram (PSG) in children with medical complexity (CMC) and to explore whether families’ goals of care (regarding results and treatment implications) were discussed prior to the completion of a PSG. Methods All CMC enrolled in a complex care program at the Hospital for Sick Children, Canada, who underwent a baseline PSG from 2009 to 2015 were identified. Exclusion criteria included (1) PSGs for ventilation titration and (2) PSGs outside the study time frame. Health records were retrospectively reviewed to determine demographics, medical histories, families’ wishes, PSG results, and their impact on clinical care. Descriptive statistics were used to summarize results. Results Of 145 patients identified, 96 patients met inclusion criteria. Fifty (52%) were male. Median age was 3 years. Forty-eight (50%) were diagnosed with clinically significant (i.e., moderate to severe obstructive sleep apnea, central sleep apnea, and/or hypoventilation) sleep-related breathing disorders. Of those diagnosed, 9 (19%) had surgery, 25 (52%) underwent respiratory technology initiation, and 3 (6%) underwent both. In the remaining 11 (23%) patients, treatment was either considered too risky or did not align with the families’ wishes. Only 3 of 96 patients had clear documentation of their families’ wishes prior to PSG completion. Conclusion Recognizing the burden of medical tests for both the child and the health care system, a process of shared-decision making that includes clarifying a family’s wishes may be prudent prior to conducting a PSG.

Abstract Introduction The impact of vitamin D on human health including sleep has been well described in adults. Its deficiency has been associated with multiple sleep disorders such as decrease in sleep duration, worsening of sleep quality and even obstructive sleep apnea. Such correlation is less evident in pediatric population. In the current study, we examined the relationship between sleep architecture and vitamin D status in children referred to a sleep clinic. Methods Retrospective-cohort study in a tertiary care children’s hospital over a one-year period. Children who underwent an in-laboratory-overnight-polysomnogram and had a 25-hydroxy vitamin D level (25-OH-vitD) obtained within 120 days of the sleep study were included. Patients with obstructive or central sleep apnea were excluded. Data from polysomnograms (PSG) and Pediatric Sleep Questionnaires (PSQ) were collected and analyzed. Results A total of 39 patients were included in the study with mean age of 6.6 years and 46% females. Twenty (51%) patients had vitamin D deficiency (25-OH-vitD less than 30 ng/ml). Children with vitamin D deficiency had less total sleep time (470.3 minutes +/-35.6 vs 420.3 minutes +/-61.7, p=0.004) and poorer sleep efficiency (91.9 % +/-5.6 vs 84.5 % +/-9.5, p=0.015) compared to vitamin D sufficient children. In addition, vitamin D deficient children had later weekday bedtimes (21:02 +/- 1:01 vs 20:19 +/- 0:55, p=0.037) and later weekend bedtimes (21:42 +/- 0:59 vs 20:47 +/- 1:08, p=0.016) with tendency for later wake up time that did not reach statistical significance. The remainder of polysomnographic findings and PSQ data were not different between the two groups. Conclusion Vitamin D deficiency in children is associated with objectively measured decreased sleep duration and poorer sleep efficiency. Furthermore, vitamin D deficiency was associated with delayed bedtimes, suggesting that vitamin D may influence circadian rhythm. Future prospective studies in children would be helpful in validating the effect of vitamin D on sleep. Support None

Abstract Introduction Sleep-related breathing disorders (SRBDs) including obstructive sleep apnea (OSA) and central sleep apnea (CSA) are quite common and are the leading causes of mortality in acromegaly. OSA in acromegaly is generally attributed to changes in oropharyngeal soft tissues. Data on OSA in Indian acromegaly are scant, especially cephalometric findings. The aim of this study is to evaluate the burden of SRBDs in acromegaly and its correlation to cephalometric parameters. Materials and Methods A total of 32 subjects (20 men and 12 women), diagnosed with acromegaly on the basis of standard clinical, biochemical, and hormonal measurements were recruited. In addition to the above parameters, polysomnography and magnetic resonance imaging (MRI) of the pharynx were performed in all subjects. Results The mean age of the subjects was 42.66 ± 11.13 years (range = 26–66) and mean duration of study after first presentation was 7.6 ± 6.3 years (range = 0.25–32). A total of 28 of 32 (93.3%) subjects had sellar MRI documented macroadenomas while 20 (62.5%) patients were treatment naive at the time of assessment. Twenty-nine (90.6%) patients had evidence of SRBD and all of them had OSA subtype. The Apnea–Hypopnea Index (AHI) indicating severity of OSA (mild 21.8%, moderate 34.4%, and severe 34.4%) correlated positively with tongue length, uvula length, and uvula thickness on MRI. However, AHI had no correlation with the severity of GH excess or disease activity or individual parameters such as weight, body mass index, blood pressure, hemoglobin A1c, serum human growth hormone, and insulin-like growth factor-1 level. Conclusion SRBD, the generally overlooked comorbidity, is highly prevalent in subjects with acromegaly and is almost always due to OSA, the severity of which correlates positively with tongue and uvula size. Well-designed, long-term follow-up study on a large cohort of acromegalic patients is required to improve our understanding on the subject.

High Prevalence

The problem of heart failure (HF) is one of the central problems in modern cardiology due to its high prevalence among the population and high mortality. In turn, sleep-related breathing disorders (SRBD) are widespread in patients with HF and are associated with both the progression of the underlying disease and a decrease in the quality of life. For the first time, periodic breathing, as one of the types of sleep breathing disorders, was described in patients with HF.Further study of the issue showed a high prevalence of other types of SRBD among patients with HF The article discusses the physiology of sleep breathing monitoring in a healthy person and the pathophysiology of SRBD. The pathogenesis of central sleep apnea and its relationship with HF are discussed in detail. In addition, the mechanisms of the adverse effect of obstructive sleep apnea and HF are highlighted.

Abstract Introduction Sleep-related breathing disorders are common after TBI. To date, two single site studies have reported divergent findings in post-TBI patients with one reporting predominantly obstructive sleep apnea (OSA, Holcomb et al., 2016) and the other central sleep apnea (CSA, Webster and Bell, 1998). The purpose of this analysis is to explore prevalence, demographics, and injury characteristics of patients with a clinical diagnosis of CSA in a recently-completed multicenter comparative-effectiveness trial during inpatient rehabilitation following moderate to severe TBI. Methods Participants in a six-center diagnostic comparative effectiveness trial underwent Level-1 polysomnography (PSG) during inpatient rehabilitation for TBI. Studies were scored at a centralized scoring center by one of two certified PSG technicians with final interpretation by a board-certified sleep medicine physician. Results 21 of 248 (8.5%) participants evidenced elevated CSA indices >5. Predominant CSA was rare (n=3 [1.2%], age range: 36-59; 100% male; 33-52 days post-TBI). One participant was on opioid, anti-depressant and antiepileptic drugs, one was on an antiepileptic, and another was on an opioid. PAP therapy was not initiated during PSG thus there was no treatment-emergent CSA. All had a central apnea-hypopnea index (AHI) in the moderate to severe range (29-49). Two out of the three had a GCS <8 and one participant had a GCS of 14. Conclusion In this multi-center clinical trial, predominant CSA was rare. The common practice of reducing polypharmacy in order to minimize sedation and optimize mental status in specialized inpatient brain-injury rehabilitation programs may contribute to the low CSA incidence in this cohort. Attention to medication side-effects and their influence on sleep-related breathing should be routinely considered.

The Impact

Obesity is a primary risk factor for the development of obstructive sleep apnea in humans, but the impact of obesity on central sleep apnea is less clear. Given the comorbidities associated with obesity in humans, we developed techniques for long-term recording of diaphragmatic EMG activity and polysomnography in obese mice to assess breathing patterns during sleep and to determine the effect of obesity on apnea generation. We hypothesized that genetically obese ob/ob mice would exhibit less variability in breathing across the 24-h circadian cycle, be more prone to central apneas, and be more likely to exhibit patterns of increased diaphragm muscle activity consistent with obstructive apneas compared with lean mice. Unexpectedly, we found that obese mice exhibited a greater circadian impact on respiratory rate and diaphragmatic burst amplitude than lean mice, particularly during rapid eye movement (REM) sleep. Central apneas were more common in REM sleep (42 ± 17 h−1) than non-REM (NREM) sleep (14 ± 5 h−1) in obese mice ( P < 0.05), but rates were not different between lean and obese mice in either sleep state. Even after experimentally enhancing central apnea generation by acute withdrawal of hypoxic chemoreceptor activation during sleep, central apnea rates remained comparable between lean and obese mice. Last, we were unable to detect patterns of diaphragmatic burst activity suggestive of obstructive apnea events in obese mice. In summary, obesity does not predispose mice to increased occurrence of central or obstructive apneas during sleep, but does lead to a more pronounced circadian variability in respiration.

The Impact

Obstructive sleep apnea (OSA) is an important and socially relevant problem of modern medicine, which is referred to as a most common pathological condition. The problem of OSA is especially urgent for inhabitants of high mountainous regions, as a combination of climatic, social, and cultural factors can significantly affect the course of the disease in both indigenous highlanders and people temporarily residing at high altitude. The paper reviews the current literature covering the problem of OSA at high altitude. It gives the data of Russian and foreign literature on the pathogenesis and clinical presentation of OSA. The author also analyzes an update on the impact of high altitude on the course of OSA in indigenous highlanders and people temporarily living at high altitude. She emphasizes the role of hypobaric hypocapnia as the most important factor for the development of central sleep apnea in the presence of conditions that are obstructive and aggravating the course of the disease.

Adults And Children

Sleep-related breathing disorders are categorized into obstructive sleep apnea syndromes, central sleep apnea syndrome, and sleep-related hypoventilation or hypoxic syndromes. These disorders can occur in adults and children. Clinical characteristics, diagnosis, and treatment are discussed in this chapter. Sleep apnea occurs when recurrent complete (apnea) or nearly complete (hypopnea) cessation of airflow develops, accompanied by preservation of the respiratory drive manifested as persistent respiratory muscle effort. Apnea is defined as the cessation of airflow for more than 10 seconds, using a valid measure of airflow. Hypopnea is an airflow reduction of at least 30% from baseline that lasts at least 10 seconds and is accompanied by an oxygen desaturation of 4% or more.

Disordered Breathing

The past two decades has seen a substantial rise in the use of opioids for chronic pain, along with opioid-related mortality and adverse effects. A contributor to opioid-associated mortality is the high prevalence of moderate/severe sleep-disordered breathing, including central sleep apnea and obstructive sleep apnea, in patients with chronic pain. Although evidence-based treatments are available for sleep-disordered breathing, patients are not frequently assessed for sleep-disordered breathing in pain clinics. To aid healthcare providers in this area of clinical uncertainty, we present evidence on the interaction between opioids and sleep-disordered breathing, and the prevalence and predictive factors for sleep-disordered breathing in patients on opioids for chronic pain. We provide recommendations on how to evaluate patients on opioids for risk of moderate/severe sleep-disordered breathing in clinical care, which could lead to earlier use of therapeutic interventions for opioid-associated sleep-disordered breathing, such as opioid cessation or positive airway pressure therapy. This would improve quality of life and well-being of patients with chronic pain.

Abstract Introduction Several studies indicated there is an association between central sleep apnea (CSA) and atrial fibrillation (AF) in older populations. However, few studies assessed the impact of ethnicity on the association. We assessed the hypothesis that ethnicity modifies the association between CSA and AF in older men. Methods We did a cross-sectional analysis using two population studies of Japanese-American (JA) and White-American (WA) men. The Kuakini Honolulu-Asia Aging Study (HAAS) is a longitudinal cohort study of JA men living in Hawaii. Sleep data were collected between 1999–2000. The Osteoporotic Fractures in Men (Mr.OS) Sleep Study was conducted between 2003–2005 on the continental U.S. The majority of Mr.OS participants were WA. We selected 79–90 year old males, who had overnight polysomnography from both studies. Total participants were 690 JA and 871 WA men. Obstructive apnea-hypopnea index (OAHI) was the measure of the number of obstructive apneas and hypopneas with &gt;4% oxygen desaturation. Additionally, the central apnea index (CAI) was the measure of the number of central apneas. Obstructive sleep apnea (OSA) was categorized as none (OAHI &lt;5), mild (OAHI 5–14), moderate (OAHI 15–29), and severe (OAHI&gt;=30). CSA was defined by CAI&gt;=5. Cheyne-Stokes breathing (CSB) was defined as a minimum consecutive 5–10 minute period of a crescendo-decrescendo respiratory pattern associated with CSA. A board-certified physician confirmed AF by single lead electrocardiography of polysomnography. Results The prevalence of AF was 5.7% in JA and 9.1% in WA. The prevalence of CSA and CSB in WA were higher than in JA (11.5% vs 6.5% and 5.7% vs 3.3%, respectively). Conversely, the prevalence of severe OSA in JA (20.7%) was higher than in WA (11.8%). In multivariable-adjusted logistic regression models, CSA was associated with higher odds of AF, and the association was stronger in JA [Odds Ratio (OR)=4.77, 95% confidence interval (CI): 1.95–11.64] than in WA (OR=2.05, 95% CI: 1.07–3.94). CSB showed similar trends as CSA. In contrast, the severity of OSA was not significantly associated with AF in either ethnicity. Conclusion Ethnicity modifies the association between CSA and AF. In older JA and WA men, screening for CSA might be important to prevent AF. Support (if any):
