Abstract Introduction The objective of this study was to compare OSA, demographic, and TBI characteristics across the American Academy of Sleep Medicine (AASM) and Centers for Medicare and Medicare (CMS) scoring rules in moderate to severe TBI undergoing inpatient neurorehabilitation. Methods This is a secondary analysis from a prospective clinical trial of sleep apnea at six TBI Model System study sites (n=248). Scoring was completed by a centralized center using both the AASM and CMS criteria for OSA. Hospitalization and injury characteristics were abstracted from the medical record and demographics obtained by interview by trained research assistants using TBI Model System standard procedures. Results OSA was prevalent using the AASM (66%) and CMS (41.5%) criteria with moderate to strong agreement (weighted kappa = 0.64 (95%CI = 0.58, 0.70). Significant differences were observed for participants meeting AASM and CMS criteria (Agreement Group; AG) compared to those meeting criteria for AASM but not CMS (Disagreement Group; DG). At AHI ≥ 5, the DG (n=61) had lower Emergency Department Glasgow Coma Scale Scores consistent with greater injury severity (median 5 vs. 13, p = 0.0050), younger age (median 38 vs 58, p<0.0001), and lower BMI (median 24.8 vs 22.1, p = 0.0007) compared to the AG (n=103). At AHI ≥ 15, female gender and but no other differences were noted possibly due to the smaller sample size. Conclusion The underestimation of sleep apnea using CMS criteria is consistent with prior literature; however, this is the first study to report the impact of the criteria in persons with moderate to severe TBI during a critical stage of neural recovery. Management of comorbidities in TBI has become an increasing focus for optimizing TBI outcomes. Given the chronic morbidity after moderate to severe TBI, the impact of CMS policy for OSA diagnosis for persons with chronic disability and young age are considerable.

Abstract Introduction A recent meta-analytic report highlighted that obstructive sleep apnea was 12 times more prevalent in TBI (mixed severity) than in community-based samples. Recent studies highlight prevalent obstructive sleep apnea during acute inpatient rehabilitation which is a time of critical neural repair. Acute sleep disturbances are associated with therapy cooperation due to effects on daytime sleepiness and are associated with key rehabilitation outcomes. Given the high rates of OSA and risk for negative morbidity, this analysis sought to examine the feasibility of administering polysomnography (PSG) with EEG to diagnose sleep apnea during inpatient rehabilitation in persons with moderate to severe TBI. Methods This is a secondary analysis from a prospective diagnostic comparative effectiveness clinical trial (NCT03033901) that took place at six NIDILRR and one VA TBI Model System Centers. Participants were included if they met the TBI Model System case definition and slept at least 2 hours per night prior to PSG. PSG was conducted following AASM procedures in the participant’s hospital bed on the inpatient rehabilitation unit. Studies were scored by RPSGT staff and interpreted by a board certified sleep medicine physician at a centralized sleep scoring center in Tampa, FL. Results Of 896 potential TBI participants, 449 met initial eligibility and 345 consented for further screening; a final sample of 263 (76%) completed PSG during hospitalization. Primary reasons for not completing PSG included early discharge or medical instability (n=59) and last-minute withdrawal of consent for PSG (n=23). Of the 263 participants who completed PSG, 3 were excluded from analysis due to technical issues and 12 were excluded as the total sleep time (TST) was less than 120 minutes. Of the 248, 85.5% of the PSGs were rated as interpretable/scoreable by RPSGT and sleep physicians. Conclusion For a majority of participants, polysomnography is feasible during inpatient rehabilitation. Participants with shorter lengths of stay, medical instability, prolonged agitation may require polysomnography follow-up after discharge.

<b><i>Objective:</i></b> The purpose of this study was to evaluate the effects of nasal surgery on airflow characteristics in patients with obstructive sleep apnea (OSA) by comparing the alterations of airflow characteristics within the nasal and palatopharyngeal cavities. <b><i>Methods:</i></b> Thirty patients with OSA and nasal obstruction who underwent nasal surgery were enrolled. A pre- and postoperative 3-dimensional model was constructed, and alterations of airflow characteristics were assessed using the method of computational fluid dynamics. The other subjective and objective clinical indices were also assessed. <b><i>Results:</i></b> By comparison with the preoperative value, all postoperative subjective symptoms statistically improved (<i>p</i> &#x3c; 0.05), while the Apnea-Hypopnea Index (AHI) changed little (<i>p</i> = 0.492); the postoperative airflow velocity and pressure in both nasal and palatopharyngeal cavities, nasal and palatopharyngeal pressure differences, and total upper airway resistance statistically decreased (all <i>p</i> &#x3c; 0.01). A significant difference was derived for correlation between the alteration of simulation metrics with subjective improvements (<i>p</i> &#x3c; 0.05), except with the AHI (<i>p</i> &#x3e; 0.05). <b><i>Conclusion:</i></b> Nasal surgery can decrease the total resistance of the upper airway and increase the nasal airflow volume and subjective sleep quality in patients with OSA and nasal obstruction. The altered airflow characteristics might contribute to the postoperative reduction of pharyngeal collapse in a subset of OSA patients.

Obstructive sleep apnea (OSA) in children is a prevalent, albeit largely undiagnosed disease associated with a large spectrum of morbidities. Overnight in-lab polysomnography remains the gold standard diagnostic approach, but is time-consuming, inconvenient, and expensive, and not readily available in many places. Simplified Home Respiratory Polygraphy (HRP) approaches have been proposed to reduce costs and facilitate the diagnostic process. However, evidence supporting the validity of HRP is still scarce, hampering its implementation in routine clinical use. The objectives were: Primary; to establish the diagnostic and therapeutic decision validity of a simplified HRP approach compared to PSG among children at risk of OSA. Secondary: (a) Analyze the cost-effectiveness of the HRP versus in-lab PSG in evaluation and treatment of pediatric OSA; (b) Evaluate the impact of therapeutic interventions based on HRP versus PSG findings six months after treatment using sleep and health parameters and quality of life instruments; (c) Discovery and validity of the urine biomarkers to establish the diagnosis of OSA and changes after treatment.

Considerable evidence is now available of an independent association between obstructive sleep apnea syndrome (OSAS) and cardiovascular disease. The association is particularly strong for systemic arterial hypertension, but there is growing evidence of an association with ischemic heart disease and stroke. The mechanisms underlying cardiovascular disease in patients with OSAS are still poorly understood. However, the pathogenesis is likely to be a multifactorial process involving a diverse range of mechanisms, including sympathetic overactivity, selective activation of inflammatory molecular pathways, endothelial dysfunction, abnormal coagulation, and metabolic dysregulation, the latter particularly involving insulin resistance and disordered lipid metabolism. Therapy with continuous positive airway pressure (CPAP) has been associated with significant benefits to cardiovascular morbidity and mortality, both in short-term studies addressing specific aspects of morbidity, such as hypertension, and more recently in long-term studies that have evaluated major outcomes of cardiovascular morbidity and mortality. However, there is a clear need for further studies evaluating the impact of CPAP therapy on cardiovascular outcomes. Furthermore, studies on the impact of CPAP therapy have provided useful information concerning the role of basic cell and molecular mechanisms in the pathophysiology of OSAS.
