Abstract
We report a case of severe central sleep apnea incidentally diagnosed during polysomnography for suspected obstructive sleep apnea. Characteristic clinical features included episodic hyperventilation followed by apnea from hypocapnia, which did not follow a Cheyne-Stokes pattern. Combined with the identification of cerebellar and brainstem malformations known as the "molar tooth sign" on a brain magnetic resonance imaging, developmental delay, and motor coordination problems, Joubert syndrome (a congenital disease) was first diagnosed at the age of 50 years. Central apneas were also observed during wakefulness, although not continuously. During sleep, continuous positive airway pressure and adaptive servo-ventilation were ineffective at the referring clinic and at our hospital. Supplemental oxygen decreased the frequency of central apneas and significantly shortened the duration of each central sleep apnea compared with room air. In contrast, the opposite response was observed with acetazolamide administration. CITATION Murashima R, Shiota S, Sugiyama A, et al.

Abstract
Many studies have shown an association of obstructive sleep apnea (OSA) with incident cardiovascular diseases, particularly when comorbid with insomnia, excessive sleepiness, obesity hypoventilation syndrome, and chronic obstructive pulmonary disease. Randomized controlled trials (RCTs) have demonstrated that treatment of OSA with positive airway pressure devices (CPAP) improves systemic hypertension, particularly in those with resistant hypertension who are adherent to CPAP. However, large RCTs have not shown long-term benefits of CPAP on hard cardiovascular outcomes, but post hoc analyses of these RCTs have demonstrated improved hard outcomes in those who use CPAP adequately. In theory, low CPAP adherence and patient selection may have contributed to neutral results in intention-to-treat analyses. Only by further research into clinical, translational, and basic underlying mechanisms is major progress likely to continue. This review highlights the various treatment approaches for sleep disorders, particularly OSA comorbid with various other disorders, the potential reasons for null results of RCTs treating OSA with CPAP, and suggested approaches for future trials.

Abstract
Determining the endotypes of obstructive sleep apnea (OSA) has potential implications for precision interventions. Here we assessed whether continuous positive airway pressure (CPAP) treatment outcomes differ across endotypic subgroups. We conducted a retrospective analysis of data obtained from 225 patients with moderate-to-severe OSA from a single sleep centre. Polysomnographic and CPAP titration study data were collected between May 2020 and January 2022. One-month CPAP treatment adherence was followed. Obstructive sleep apnea endotypes, namely arousal threshold, collapsibility, loop gain, and upper airway gain were estimated from polysomnography and dichotomised as high versus low. We examined associations between endotypic subgroups and (1) optimal CPAP titration pressure, (2) CPAP-related improvements in sleep architecture (proportions of slow-wave and rapid eye movement (REM) sleep), and (3) CPAP adherence. We observed that patients with high collapsibility required a higher CPAP pressure than those with low collapsibility (∆ = 0.4 cmH2 O, 95% confidence interval [CI] = 0.3-1.7). A larger increase in slow-wave sleep and in REM sleep proportions after CPAP treatment were observed in patients with a high arousal threshold, high collapsibility, high loop gain, or high upper airway gain than in those with low levels of endotypes. High loop gain and high collapsibility were independently associated with longer CPAP use hours per night (∆ = 0.6 h, 95% CI = 0.2-1.5 and ∆ = 0.3 h, 95% CI = 0.03-1.5, respectively). In conclusion, different endotypic subgroups of OSA exhibit a difference in outcomes of CPAP treatment. Knowledge of endotypes may help clinicians to understand which patients are expected to benefit most from CPAP therapy prior to its administration.

Abstract
Guidelines for management of sleep disorders from national or regional societies provide recommendations that may be regionally appropriate but may not always be practical or relevant in other parts of the world. A task force of experts from the World Sleep Society's (WSS) International Sleep Medicine Guidelines Committee and Sleep and Breathing Disorders Task Force reviewed the European Respiratory Society's guideline on non-CPAP therapies for obstructive sleep apnea (OSA) with respect to its relevance and applicability to the practice of sleep medicine by sleep specialists in various regions of the world. The task force and the WSS guidelines committee endorsed the European Respiratory Society's guideline with respect to the utilization of bariatric surgery, mandibular advancement devices, positioning devices, myofunctional therapy, hypoglossal neurostimulation, maxilo-mandibular surgery, and carbonic anhydrase inhibitors for the treatment of OSA. The task force and the WSS guidelines committee noted that there is substantial new evidence for the role of soft tissue, upper airway surgery, not included in the guidelines paper.

Abstract
Central sleep apnoea (CSA) is a sleep disorder characterized by the repeated cessation or reduction of both airflow and ventilatory effort when sleeping. Individuals with central breathing disorders have difficulty in receiving appropriate medical treatment. In this article, we describe a case study of a 31-year-old woman known to have multiple sclerosis and concomitant severe CSA. She received the medication dimethyl fumarate for the treatment of multiple sclerosis, and her CSA significantly improved to mild CSA after the treatment.

Abstract
INTRODUCTION Clinical presentation of both insomnia and obstructive sleep apnea (COMISA) is common. Approximately 30% of clinical cohorts with OSA have insomnia symptoms and vice versa. The underlying pathophysiology of COMISA is multifactorial. This poses a complex clinical challenge. Currently, there are no clinical guidelines or recommendations outside of continuous positive airway pressure (CPAP) therapy and cognitive behavioral therapy for insomnia (CBTi). Clinically translatable precision medicine approaches to characterize individual causes or endotypes may help optimize future pharmacological management of COMISA. AREAS COVERED This review article provides an up-to-date account of COMISA and its consequences, the underlying pathophysiology of sleep apnea, insomnia and COMISA, current treatment approaches and limitations, pharmacotherapy targets and future priorities. EXPERT OPINION There are multiple promising emerging therapies, but clinical trial data specifically in COMISA populations are lacking. This is a priority for future investigation to inform development of evidence-based guidelines. Pharmacotherapies, particularly for insomnia, do not target the underlying causes of the disorder thus, are indicated for short-term use only and should remain second line. Future multidisciplinary research should be directed toward the multifactorial nature of COMISA and the challenges of adapting COMISA treatment in clinical practice and overcoming the practical barriers that health-care providers and consumers encounter.

Abstract
Obstructive sleep apnea syndrome (OSAS) is a common breathing disorder in sleep in which the airways narrow or collapse during sleep, causing obstructive sleep apnea. The prevalence of OSAS continues to rise worldwide, particularly in middle-aged and elderly individuals. The mechanism of upper airway collapse is incompletely understood but is associated with several factors, including obesity, craniofacial changes, altered muscle function in the upper airway, pharyngeal neuropathy, and fluid shifts to the neck. The main characteristics of OSAS are recurrent pauses in respiration, which lead to intermittent hypoxia (IH) and hypercapnia, accompanied by blood oxygen desaturation and arousal during sleep, which sharply increases the risk of several diseases. This paper first briefly describes the epidemiology, incidence, and pathophysiological mechanisms of OSAS. Next, the alterations in relevant signaling pathways induced by IH are systematically reviewed and discussed. For example, IH can induce gut microbiota (GM) dysbiosis, impair the intestinal barrier, and alter intestinal metabolites. These mechanisms ultimately lead to secondary oxidative stress, systemic inflammation, and sympathetic activation. We then summarize the effects of IH on disease pathogenesis, including cardiocerebrovascular disorders, neurological disorders, metabolic diseases, cancer, reproductive disorders, and COVID-19. Finally, different therapeutic strategies for OSAS caused by different causes are proposed. Multidisciplinary approaches and shared decision-making are necessary for the successful treatment of OSAS in the future, but more randomized controlled trials are needed for further evaluation to define what treatments are best for specific OSAS patients.

Abstract
BACKGROUND The acute effect during positive pressure titration and long term efficacy of acetazolamide (AZT) in high loop gain sleep apnea (HLGSA) is inadequately assessed. We predicted that AZT may improve HLGSA in both conditions. METHODS A retrospective analysis of polysomnograms from patients with presumed HLGSA and residual respiratory instability administered AZT (125 or 250 mg) about 3 h into an initially drug-free positive pressure titration. A responder was defined as ≥ 50% reduction of the apnea hypopnea index(AHI 3% or arousal) before and after AZT. A multivariable logistic regression model estimated responder predictors. Long term efficacy of AZT was assessed by comparing both auto-machine (aREIFLOW) and manually scored respiratory events (sREIFLOW) extracted from the ventilator, prior to and after 3 months of AZT, in a subset. RESULTS Of the 231 participants (median age of 61[51-68] years) and 184 (80%) males in the acute effect testing: 77 and 154 patients were given 125 mg and 250 mg AZT. Compared to PAP alone, PAP plus AZT was associated with a lower breathing related arousal index (8 [3-16] vs. 5 [2-10], p < 0.001), and AHI3% (19 [7-37] vs. 11 [5-21], p < 0.001); 98 patients were responders. The non-rapid eye movement sleep (NREM) AHI3% (OR 1.031, 95%CI [1.016-1.046], p < 0.001) was a strong predictor for responder status with AZT exposure. In the 109 participants with 3-month data, both aREIFLOW and sREIFLOWwere significantly reduced after AZT. CONCLUSIONS AZT acutely and chronically reduced residual sleep apnea in presumed HLGSA; NREM AHI3% is a response predictor. AZT was well tolerated and beneficial for at least 3 months.

Abstract
OBJECTIVE Unexplained significant central sleep apnea in term infants presents as central apneas with associated oxygen desaturations requiring respiratory support and monitoring for prolonged periods. However, there is a paucity of literature describing idiopathic central sleep apnea (ICSA) in term or near-term infants. Our aim was to describe the clinical manifestations, polysomnography data, interventions, and trajectory of ICSA in infants. DESIGN This is a retrospective study of infants (gestational age ≥ 35 weeks) who presented with significant central apneas and were subsequently diagnosed with ICSA following polysomnography and clinical investigations between January 2011 and April 2021 at a tertiary care hospital in Canada. Polysomnography data, clinical investigations, and treatments were documented. RESULTS Eighteen infants (male, 78%; median gestational age 38 weeks) with ICSA were included. Initial polysomnograms were completed at a median (interquartile range [IQR]) age of 1.2 (0.6-1.6) months (n = 18) and follow-up polysomnograms at 12.4 (10.6-14.0) months (n = 13). Compared to baseline diagnostic polysomnograms, at follow-up there was a significant reduction in the median (IQR) central apnea-hypopnea index (26.1 [18.2-52.9] versus 4.2 [2.6-7.2] events/hour; p = 0.001), desaturation index (30.9 [12.2-57.4] versus 3.9 [3.0-7.9] events/hour; p = 0.002), average transcutaneous carbon dioxide (41.9 [40.1-47.3 versus 39.4 [37.5-42.7] mmHg; p = 0.025), and improved nadir oxygen saturation (79.8 [69.1-83.0] versus 85.5 [83.2-87.8]%; p = 0.033), respectively. Prescribed treatments included supplemental oxygen (14/18, 78%), caffeine (5/18, 28%), and noninvasive ventilation (1/18, 6%). CONCLUSIONS Infants with significant unexplained ICSA have a favorable clinical trajectory over time. Further research is needed to understand the etiology of this rare disorder.

Abstract
Obstructive sleep apnoea is a challenging medical problem due to its prevalence, its impact on quality of life and performance in school and professionally, the implications for risk of accidents, and comorbidities and mortality. Current research has carved out a broad spectrum of clinical phenotypes and defined major pathophysiological components. These findings point to the concept of personalised therapy, oriented on both the distinct clinical presentation and the most relevant pathophysiology in the individual patient. This leads to questions of whether sufficient therapeutic options other than positive airway pressure (PAP) alone are available, for which patients they may be useful, if there are specific indications for single or combined treatment, and whether there is solid scientific evidence for recommendations. This review describes our knowledge on PAP and non-PAP therapies to address upper airway collapsibility, muscle responsiveness, arousability and respiratory drive. The spectrum is broad and heterogeneous, including technical and pharmaceutical options already in clinical use or at an advanced experimental stage. Although there is an obvious need for more research on single or combined therapies, the available data demonstrate the variety of effective options, which should replace the unidirectional focus on PAP therapy. The analysis of individual pathophysiological composition opens new directions towards personalised treatment of OSA, focusing not only on pharyngeal dilation, but also on technical or pharmaceutical interventions on muscle function or breathing regulationhttps://bit.ly/3sayhkd

Abstract
Background Heart failure with reduced ejection fraction (HFrEF) is a clinical condition frequently diagnosed in clinical practice. In patients affected by HFrEF, sleep apnea (SA) can be detected among the most frequent comorbidities. Sacubitril–valsartan (sac/val) association has been proven to be effective in reducing disease progression and all-cause mortality in HFrEF patients. Sac/val treatment can potentially attenuate SA development via several pathophysiologic mechanisms, including improvement of global hemodynamics, reduction of extracellular fluid overload, and decrease of sympathetic neural activity. Methods We recruited 132 patients affected by HFrEF and SA, already under treatment with continuous positive airway pressure (CPAP), which was discontinued 24 h before the scheduled study timepoints. Physical examination, echocardiography, nocturnal cardio-respiratory monitoring, and laboratory tests were performed in each patient at baseline and after a 6-month treatment with sac/val. Results After 6 months, sac/val induced statistically significant changes in clinical, hemodynamic, biohumoral (NT-proBNP, serum electrolytes, creatinine, and uric acid), and echocardiographic parameters. In particular, cardiac index (CI), both atrial and ventricular volumes and global longitudinal strain (GLS) improved. Moreover, polysomnography, carried out during a temporary CPAP interruption, revealed a significant reduction in global apnea-hypopnea index (AHI) value (p < 0.0001), central AHI (p < 0.0001), obstructive AHI (p < 0.0001), oxygen desaturation index (ODI) (p < 0.0001), and percentage time of saturation below 90% (TC90) (p < 0.0001). The changes of CI, estimated glomerular filtration rate (eGFR), NT-proBNP, and tricuspid annular plane excursion (TAPSE) contributed to 23.6, 7.6, 7.3, and 4.8% of AHI variability, respectively, and the whole model accounted for a 43.3% of AHI variation. Conclusions Our results suggest that treatment with sac/val is able to significantly improve the cardiorespiratory performance of patients with HFrEF and SA, integrating the positive impact of CPAP. Thus, both CPAP and sac/val therapy may synergistically contribute to lower the risks of both cardiac and pulmonary complications in HFrEF patients with SA.

Abstract
RATIONAL Current therapies in obstructive sleep apnea (OSA) are limited by insufficient efficacy, compliance or tolerability. An effective pharmacological treatment in OSA is warranted. Carbonic anhydrase (CA) inhibition has been shown to ameliorate OSA. OBJECTIVE To explore safety and tolerability of the CA inhibitor sulthiame (STM) in OSA. METHODS A four week double-blind, randomized, placebo-controlled dose guiding trial in patients with moderate/severe OSA not tolerating positive airway pressure treatment. MEASUREMENTS AND RESULTS Intermittent paresthesia was reported by 79, 67 and 18% of patients receiving 400 mg STM (N=34), 200 mg STM (N=12) or placebo (N=22), respectively. Dyspnea was reported only after 400 mg STM (18%). Six patients in the higher dose group withdrew due to an adverse event. There were no serious adverse events. STM reduced the apnea-hypopnea index (AHI) from 55.3 to 33.1 events/h ( 41.0%) in the 400 mg group and from 61.2 to 40.7 events/h ( 32.1%) after 200 mg (p<0.001, respectively). Corresponding placebo values were 53.9 and 50.9 events/h ( 5.4 %). The AHI reduction threshold of ≥50% was reached in 40% after 400 mg, 25% after 200 mg and 5% following placebo. Mean overnight oxygen saturation improved by 1.1% after 400 mg and 200 mg (p<0.001 and p=0.034, respectively). Patient related outcomes were unchanged. CONCLUSIONS STM showed a satisfactory safety profile in moderate/severe OSA. STM reduced OSA by more than 20 events/h, one of the strongest reductions reported in a drug trial in OSA. Larger scale clinical studies of STM in OSA are justified. Clinical trial registration available at https://www.clinicaltrialsregister.eu/https://www.clinicaltrialsregister.eu/, ID: 2017-004767-13.

Abstract
ZusammenfassungDie obstruktive Schlafapnoe (OSA) kann zu einer erheblichen Einschränkung der Lebensqualität führen, und eine nicht behandelte mittel- bis schwergradige OSA (Apnoe-Hypopnoe-Index ≥ 15/h) erhöht das Risiko vieler – überwiegend kardiovaskulärer – Erkrankungen deutlich. In Anbetracht der Häufigkeit des Krankheitsbilds und der damit verbundenen Beeinträchtigungen ist eine effektive Diagnostik und Therapie der OSA von besonderer Bedeutung.Die Deutsche Gesellschaft für Schlafforschung und Schlafmedizin (DGSM) hat daher jeweils fünf praxisnahe Positiv- und Negativempfehlungen zusammengestellt, die das diagnostische und therapeutische Vorgehen bei OSA erleichtern sollen. Sie beziehen sich insbesondere auf die Indikationen zur schlafmedizinischen Diagnostik und zu spezifischen Therapieoptionen unter Berücksichtigung von Alter, Klinik, Risikofaktoren und Komorbiditäten.Die Auswahl der Empfehlungen orientiert sich an der klinischen Relevanz, an bestehenden Defiziten im Sinne einer Über- oder Unterversorgung und an der Stärke der Empfehlungen in der aktuellen S3-Leitlinie der DGSM zu den schlafbezogenen Atmungsstörungen.
