Abstract Study Objectives To determine the associations of sleep-disordered breathing (SDB) with subsequent healthcare costs and utilization including inpatient and post-acute care facility stays among community-dwelling older men. Methods Participants were 1,316 men (mean age 76.1 [SD = 5.7] years) in the Outcomes of Sleep Disorders in Older Men (MrOS sleep) study (from December 2003 to March 2005), who were enrolled in a Medicare Fee-For-Service plan. Primary SDB measures including apnea hypopnea index (AHI) and oxygen desaturation index (ODI) were collected using in-home level 2 polysomnography. Incident healthcare costs and utilization were determined from claims data in the subsequent 3-year period post-MrOS sleep visit. Results Five hundred and twenty-nine (40.2%) men had at least one hospitalization in the 3-year period. Compared with those without sleep apnea (AHI < 5/hour), men with moderate to severe sleep apnea (AHI ≥ 15/hour) had a higher odds of all-cause hospitalization (odds ratio [OR] adjusted for age and site 1.43, 95% confidence interval [CI]: 1.07–1.90). This association was slightly attenuated after further adjustment for traditional prognostic factors including education, body mass index, comorbid medical conditions, and health status (OR = 1.36; 95% CI: 1.01–1.83). Similar associations were observed for ODI. However, measures of SDB were not related to subsequent healthcare costs (total or outpatient) or odds of post-acute skilled nursing facility stay. Conclusions Older men with SDB have an increased risk of hospitalization, not entirely explained by the greater prevalence of comorbid conditions, but not higher subsequent total healthcare costs. These findings indicate a need to evaluate the impact of SDB treatment on subsequent healthcare utilization.

Disordered Breathing

Abstract Introduction Achondroplasia (ACH) occurs approximately 1 in 20,000–30,000 live births. They are prone to sleep disordered breathing specifically due to the upper airway stenosis, enlarged head circumference, combined with hypotonia and limited chest wall size associated with scoliosis at times. The co-occurrence of sleep apnea is well established and can aide in the decision for surgical intervention, however it is unclear at what age children should be evaluated for sleep apnea. Screening is often delayed as during the daytime there is no obvious gas exchange abnormalities. Due to the rareness of this disease, large studies are not available, limiting the data for discussion and analysis to develop guidelines on ideal screening age for sleep disordered breathing in children with ACH. Methods The primary aim of this study is to ascertain the presence of sleep disorder breathing and demographics of children with ACH at time of first polysomnogram (PSG) completed at one of the largest pediatric sleep lab in the country. The secondary aim of the study is to identify whether subsequent polysomnograms were completed if surgical interventions occurred and how the studies differed over time with and without intervention. Retrospective review of the PSGs from patients with ACH, completed from 2017–2019 at the Children’s Sleep Disorders Center in Dallas, TX. Clinical data, demographics, PSG findings and occurrence of interventions were collected. Results Twenty-seven patients with the diagnosis of ACH met criteria. The average age at the time of their first diagnostic PSG was at 31.6 months of age (2.7 years), of those patients 85% had obstructive sleep apnea (OSA),51% had hypoxemia and 18% had hypercapnia by their first diagnostic sleep study. Of those with OSA, 50% were severe. Majority were females, 55%. Most of our patients were Hispanic (14%), Caucasian (9%), Asian (2%), Other (2%), Black (0%). Each patient had an average of 1.9 PSGs completed. Conclusion Our findings can help create a foundation for discussion of screening guidelines. These guidelines will serve to guide primary care physicians to direct these patients to an early diagnosis and treatment of sleep disordered breathing. Support (if any):

Abstract Introduction With steadily growing numbers of patients with a depressive disorder, the effect of antidepressants on sleep architecture is of increasing concern. One major oral antidepressant medication is trazadone, which has also been prescribed in low doses for sleep insomnia treatment. Here, we investigate the effect of trazadone on NREM sleep instability also known as cyclic alternating pattern (CAP) in community-dwelling older men. Methods CAP was scored in overnight EEG recordings from 41 older men on trazadone (TRZ) and 50 age-matched men who did not use trazadone (NTRZ), participating in the Osteoporotic Fractures in Men Sleep Study. A high performance automated detection system determined the ratio between CAP time and NREM sleep time (CAP rate), the number of A1-phases per hour of NREM sleep (A1 index), and the number of A2+A3-phases per hour of NREM sleep (A2+A3 index). The effect of TRZ on CAP parameters was determined using the Mann-Whitney U test. Results CAP rate was significantly decreased in men using trazadone (NTRZ: 58.2±19.7%, TRZ: 47.9±15.9%) as compared to non-trazadone user (p < 0.01). Subtype indices did not show any significant difference between both groups but to some extent less frequent A2-A3 phases for TRZ user (A1-phases: NTRZ 13.0±18.7 no./h vs. TRZ 10.8±20.4 no./h, p = 0.35; A2+A3-phases: NTRZ 51.5±33.7 no./h vs. TRZ 44.7±23.3 no./h, p = 0.068). Conclusion CAP rate was significantly decreased in older men on trazadone as compared to older men who did not use trazadone, suggesting that trazadone usage has a stabilising effect on sleep micro-structure.

Background: Arterial stiffness is a well-recognized predictor of cardiovascular disease (CVD). ECG R-wave to Radial artery pulse delay (RRD) is a novel hemodynamic index in which arterial stiffness is an important component (shorter delay = Higher arterial stiffness) and is obtainable from a single tonometric measurement at the radial artery with simultaneous ECG. Sleep disordered breathing (SDB) has emerged as a risk factor for CVD. The aim of the study was to determine the association of SDB with RRD. Methods: Multi-Ethnic Study of Atherosclerosis participants in 2010-2012 without overt CVD who underwent a sleep study, radial artery tonometry and cardiac MRI were eligible for this cross-sectional analysis (N = 1173, Mean [SD] age: 67.8 ± 8.8, Women: 55.4%). Independent associations between SDB indices including apnea hypopnea index (AHI) and oxygen (O2) desaturation index (ODI: events with more than 4% O2 desaturation), and RRD (transit time in msec) were examined. Model was constructed to adjust for isovolumetric contraction time, another component of RRD, by including measures of contractility and preload (left ventricular ejection fraction (LVEF) and left ventricular end diastolic volume (LVEDV) respectively). Results: Median [IQR] of AHI and ODI were 7.9/hr [2.9- 18.0] and 7.5/hr [3.0- 17.5] respectively. Adjusting for transit path length, demographic factors, BMI and CVD risk factors, both AHI and ODI were inversely associated with RRD (β= -50.3 msec per SD, p = 0.09 and β= -0.60.2 msec per SD, p = 0.04 respectively). In gender stratified analyses given presence of significant interaction, measures of SDB were predictive of RRD only in men. No significant associations were found with key nocturnal hypoxemia indices including mean O2 saturation (SpO2), percent time with SpO2less than 90 % and minimum SpO2. Men, older age, Asian race, high blood pressure, LVEF and LVEDV were also inversely associated with RRD. Conclusion: SDB was associated with shorter RRD implying higher arterial stiffness in men only. These findings suggest the importance of apnea related dynamic change in SpO2 (intermittent hypoxia and reoxygenation) in its potential link to arterial stiffness and also highlights effect modification by gender in the association between the two.

Respiratory frequency (fR) predicts in-hospital and short-term mortality in patients with a variety of pathophysiological conditions, but its predictive value for long-term cardiovascular and all-cause mortality in the general population is unknown. Here, we investigated the relationship between mean nocturnal fR and mortality in community-dwelling older men and women.We measured mean nocturnal fR during sleep from overnight polysomnography in 2686 men participating in the Osteoporotic Fractures in Men Study (MrOS) Sleep study and 406 women participating in the Study of Osteoporotic Fractures (SOF) to investigate the relationship between mean nocturnal fR and long-term cardiovascular and all-cause mortality.166 (6.1%) men in the MrOS cohort (8.9±2.6 years’ follow-up) and 46 (11.2%) women in the SOF cohort (6.4±1.6 years’ follow-up) died from cardiovascular disease. All-cause mortality was 51.2% and 26.1% during 13.7±3.7 and 6.4±1.6 years’ follow-up in the MrOS Sleep study and the SOF cohorts, respectively. Multivariable Cox regression analysis adjusted for significant covariates demonstrated that fR dichotomised at 16 breaths·min−1 was independently associated with cardiovascular mortality (MrOS: hazard ratio (HR) 1.57, 95% CI 1.14–2.15; p=0.005; SOF: HR 2.58, 95% CI 1.41–4.76; p=0.002) and all-cause mortality (MrOS: HR 1.18, 95% CI 1.04–1.32; p=0.007; SOF: HR 1.50, 95% CI 1.02–2.20; p=0.04).In community-dwelling older men and women, polysomnography-derived mean nocturnal fR ≥16 breaths·min−1 is an independent predictor of long-term cardiovascular and all-cause mortality. Whether nocturnal mean fR can be used as a risk marker warrants further prospective studies.
