BackgroundObstructive sleep apnoea (OSA) is common in children with Down syndrome (DS), yet difficult to treat. As muscular hypotonia of the upper airway may cause OSA and is also common in DS, we tested whether intense myofunctional therapy improves OSA in children with DS.Patients and methodsForty-two children underwent cardiorespiratory sleep studies immediately before and after a 1-week intensive training camp consisting of three daily 45 min sessions of myofunctional exercises according to Padovan. Primary outcome was the mixed-obstructive-apnoea/hypopnoea index (MOAHI), secondary outcomes the ≤3% oxygen desaturation index (DI3), the ≤90% desaturation index (DI90) and the lowest pulse oximeter saturation (SpO2nadir).ResultsEighteen recordings had ≥3 hours of artefact-free recording in both the pretreatment and post-treatment sleep study and were therefore included in the analysis. Mean age was 6.3 years (SD 2.5); 83% had OSA prior to intervention. Mean MOAHI was 6.4 (SD 8.6) before and 6.4 (SD 10.8) after the intervention (p>0.05); the DI3 and SpO2nadir also did not change. Only the DI90 decreased significantly from 2.7 (SD 4.5) to 2.1 (SD 3.7) (p<0.05).ConclusionThe 1-week intense myofunctional training camp evaluated here in children with DS had only a marginal effect on OSA. Whether a longer follow-up period or duration of intervention would yield stronger effects remains to be determined.

Obstructive Sleep

Obstructive sleep apnoea (OSA) represents a significant global health burden, with impact on cardiometabolic health, chronic disease, productivity loss and accident risk. Oral appliances (OA) are an effective therapy for OSA and work by enlarging and stabilising the pharyngeal airway to prevent breathing obstructions during sleep. Although recommended in clinical guidelines for OSA therapy, they are often considered only as second-line therapy following positive airway pressure (PAP) therapy failure. There has been a long-standing barrier to selecting OA over PAP therapy due to the inability to be certain about the level of efficacy in individual OSA patients. A range of methods to select OSA patients for OA therapy, based on the outcome of a single sleep study night, have been proposed, although none has been widely validated for clinical use. Emergent health outcome data suggest that equivalent apnoea–hypopnea index reduction may not be necessary to produce the same health benefits of PAP. This may be related to the more favourable adherence to OA therapy, which can now be objectively verified. Data on longer term health outcomes are needed, and there are additional opportunities for device improvement and combination therapy approaches. OAs have an important role in precision care of OSA as a chronic disorder through a multi-disciplinary care team. Future studies on real-world health outcomes following OA therapy are needed.

Increased Risk

Professional drivers show a higher prevalence of obstructive sleep apnoea (OSA) compared with the general population. Furthermore, there is concern about the association between OSA and car crash risk given that drivers with OSA show an increased risk for car accidents. Despite this risk, OSA is often underdiagnosed and undertreated in this population, mainly due to lack of appropriate screening and sleep study referrals. Polysomnography (PSG), the gold standard test, is inappropriate for systematic screening because of its high expense, complexity and relative inaccessibility in this population. Therefore, there is a strong demand for good screening tools, including both subjective and objective data that may assist in early identification of possible OSA among professional drivers and, thus, aid in PSG examination referral and OSA management in an accredited sleep centre. However, there is considerable disagreement over screening methods and criteria for triggering a sleep study referral in different countries. There is also a strong need for further research in the area of OSA screening of commercial drivers in order to improve the diagnostic accuracy of screening tools and ensure that patients with OSA are accurately identified.Key pointsObstructive sleep apnoea (OSA) is often undiagnosed and undertreated in professional drivers.Professional drivers often under-report and are reluctant to report OSA symptoms.Barriers to OSA diagnosis include appropriate screening and sleep study referrals.Screening tools including both subjective and objective data may assist in early identification of possible OSA among professional drivers.Educational aimsTo evaluate screening instruments currently used to identify OSA risk in professional drivers.To provide guidance for developing an assessment strategy for OSA by professional driver medical examiners.

BackgroundIt is current practice to use a single diagnostic sleep study in the diagnostic workup of obstructive sleep apnoea (OSA). However, a relevant night-to-night variability (NtNV) of respiratory events has been reported.MethodsWe evaluated the NtNV of respiratory events in adults with suspected or already diagnosed OSA who underwent more than one diagnostic sleep study. Data sources were PubMed, Cochrane and Embase up to 23 January 2019. Random-effects models were used for evidence synthesis. For moderator analysis, mixed-effects regression analysis was performed. The study was registered with PROSPERO (CRD42019135277).ResultsOf 2143 identified papers, 24 studies, comprising 3250 participants, were included. The mean Apnoea-Hypopnoea Index (AHI) difference between the first and second night was −1.70/hour (95% CI −3.61 to 0.02). REM time differences (first to second night) were significantly positive associated with differences in mean AHI (β coefficient 0.262 (95% CI 0.096 to 0.428). On average, 41% (95% CI 27% to 57%) of all participants showed changes of respiratory events >10/hour from night to night. Furthermore, 49% (95% CI 32% to 65%) of participants changed OSA severity class (severity thresholds at 5/hour, 15/hour and 30/hour) at least once in sequential sleep studies. Depending on the diagnostic threshold (5/hour, 10/hour or 15/hour), on average 12% (95% CI 9% to 15%), 12% (95% CI 8% to 19%) and 10% (95% CI 8% to 13%) of patients would have been missed during the first night due to single night testing.ConclusionWhile there was no significant difference between mean AHI in two sequential study nights on a group level, there was a remarkable intraindividual NtNV of respiratory events, leading to misdiagnosis and misclassification of patients with suspected OSA.

Abstract Background The current health care system is challenged with a large and rising demand for obstructive sleep apnoea (OSA) services. A paradigm shift in OSA management is required to incorporate the preferences of diagnosed patients and individuals at high-risk of OSA. This study aimed to provide empirical evidence of the values and preferences of individuals diagnosed with OSA and high-risk populations regarding distinct OSA care pathway features. Methods A discrete choice experiment (DCE) was undertaken in two groups: those with a formal diagnosis of OSA (n=421) and those undiagnosed but at high-risk of having OSA (n=1033). The DCE approach used mixed logit regression models to determine preferences relating to eight salient features of OSA management pathway, i.e. initial assessment, setting and diagnosis costs, waiting times, results interpretation, treatment options, provider of ongoing care and frequency of follow up visits. Results The findings indicate that all eight attributes investigated were statistically significant factors for respondents. Generally, both groups preferred low diagnostic costs, fewer follow-up visits, minimum waiting time for sleep study results, and sleep specialists to recommend treatment and as ongoing care providers. Management of OSA in primary care was acceptable to both groups and was the most preferred option by the high-risk group for sleep study testing and ongoing care provision. Discussion The DCE results offer a promising approach for systematic incorporation of patient and high-risk groups preferences into the future design and delivery of care pathways for OSA management.

Cardiovascular Morbidity And Mortality

Background: Dyslipidaemia is well recognised in obstructive sleep apnoea (OSA) and could contribute to the development of cardiovascular disease (CVD). Atherogenic index of plasma (AIP) predicts cardiovascular morbidity and mortality better than the individual lipid levels. The aim of this study was to investigate the AIP in patients with OSA in relation with disease severity. Methods: Four hundred sixty-one patients with OSA and 99 controls participated in this study. AIP was assessed in the morning following a diagnostic sleep study. The association between lipid values and OSA were adjusted for age, gender, and body mass index. Results: Patients with OSA had higher AIP and triglyceride, and lower high-density lipoprotein cholesterol (HDL-C) levels (all p < 0.05). AIP significantly correlated with the Epworth Sleepiness Scale score (ρ = 0.19), the apnoea-hypopnoea index (ρ = 0.40) and oxygen desaturation index (ρ = 0.43, all p < 0.05). However, there was no relationship between the AIP and markers of sleep quality such as total sleep time, sleep period time, sleep efficiency, arousal index or percentage of REM sleep (all p > 0.05). AIP was not a better predictor for self-reported cardiovascular disease or diabetes than HDL-C. Conclusions: AIP is elevated in OSA and is related to disease severity. However, it does not seem to have an additional clinical value compared to HDL-C.

We evaluated whether obstructive sleep apnoea (OSA) was related to the incidence of hospitalisation for depression, a robust end-point that is unlikely to result from misdiagnosis.All adults referred with suspected OSA who underwent a diagnostic sleep study at a large urban academic hospital between 1994 and 2010 and were linked to provincial health administrative data between 1991 and 2015 were included. Cox regression analysis was used to investigate the association between OSA symptoms and severity and incident hospitalised depression, the primary outcome.Over a median follow-up of 9.7 years, 136 (1.3%) out of 10 149 participants were hospitalised for depression. A significant crude effect of OSA symptoms (waking unrefreshed and impact on memory and concentration) on hospitalised depression became nonsignificant after controlling for confounders. Apnoea–hypopnoea index was not significantly associated with the outcome: adjusted hazard ratio (33 versus6 events·h−1) 1.13 (95% CI 0.91–1.40). Factors associated with hospitalised depression were female sex, younger age, use of hypnotics, alcoholism and unemployment.In a large clinical cohort with suspected OSA, controlling for confounders, OSA symptoms and severity were not related to the risk of hospitalisation for depression, suggesting that previously reported links between OSA and depression may be due to overlapping diagnostic criteria. However, our findings cannot exclude a potential link between OSA and milder depression.

Significant Mortality

AbstractA questionnaire was sent to consultant Otolaryngologists (483) throughout the UK to identify any mortality associated with uvulopalatoplasty and other forms of palatoplasties for snoring and/or obstructive sleep apnoea. The response rate was 76.8 per cent (371). Six intra- and post-operative deaths were reported and four were known to have obstructive sleep apnoea. Life-threatening morbidity occurred in at least seven patients (three known apnoeic), two required immediate tracheostomy and two were managed in the intensive care unit. This suggests that the apnoeic patients undergoing palatoplasties experienced significant mortality and morbidity. Pre-operative sleep study should be performed in all snoring patients to identify the apnoeic subgroup. Continuous positive airway pressure, management of excessive obesity, elective tracheostomy and other strategies should be first considered before palatoplasties in these patients.
