Abstract Introduction There is lack of clarity of sleep disordered breathing (SDB)--including the role of nocturnal hypoxia and confounding influence of obesity--on the clinical course of human coronavirus disease 2019 (COVID-19). We postulate that SDB portends increased risk of adverse COVID-19 clinical outcomes even after accounting for confounding factors. Methods A retrospective cohort analysis of COVID-19 and sleep laboratory observational registries March-November 2020 within the Cleveland Clinic health system was performed. Ordinal logistic regression assessed the association of SDB indices and World Health Organization (WHO)-7 COVID-19 clinical outcome (hospitalization, use of supplemental oxygen, non-invasive ventilation, mechanical ventilation/ECMO and death) in an unadjusted model and adjusted for age, sex, race, body mass index(BMI,kg/m2),diabetes mellitus, hypertension, coronary artery disease, heart failure, asthma, chronic obstructive pulmonary disease (COPD), cancer and smoking using SAS software. Results Of 19,449 (32%) patients positive for SARS-CoV-2,2,290 (6%) had an available sleep study. The analytic sample included 1788 of which 1,484(64%) had an apnea hypopnea index (AHI, 3–4% hypopnea oxygen desaturation)≥5. The median duration from sleep study to COVID test was 5.8 years (IQR:3.3–9.0). Age was 56.5±14.4 years,50.4% female,28% African American with BMI=35.9±8.9kg/m2. Nine percent of patients were hospitalized,10% with supplemental oxygen,6% used non-invasive ventilation,2% required ECMO or mechanical ventilation and 2% died. For every AHI increase of 5, the odds of a higher WHO-7 level increased 2% (OR=1.02,95%CI1.01-1.04,p=0.005),but the association was mitigated in the adjusted model (OR=1.00,95%CI:0.98,1.02,p=0.80). Per 5% increase in time spent with SaO2<90%, the odds of a higher WHO-7 level increased 10% (OR=1.10,95%CI1.06-1.13,p=<0.001) persisting in the adjusted model(OR=1.06,95%CI:1.02–1.10,p=0.002). For every decrease of 5% mean SaO2, the odds of a higher level WHO-7 increased 56% (OR=0.56,95%CI:0.46–0.67,p<0.001) persisting in the adjusted model(OR=0.72,95%CI:0.58–0.89,p=0.003). Conclusion Even after adjustment for obesity, underlying cardiopulmonary disease and smoking, sleep-related hypoxemia was a potential key pathophysiologic mechanism associated with increased morbidity and mortality in COVID-19. Elucidation of sleep-related hypoxemia as a risk stratification measure, particularly given the silent hypoxia inherent to early COVID-19, is critical for future investigation, as is the role of sleep-related hypoxia reversal as a target to improve COVID-19 outcomes.

Abstract Background The most common cause of respiratory failure in premature infants is respiratory distress syndrome. Historically, respiratory distress syndrome has been treated by intratracheal surfactant injection followed by mechanical ventilation. In view of the risk of pulmonary injury associated with mechanical ventilation and subsequent chronic pulmonary lung disease, less invasive treatment modalities have been suggested to reduce pulmonary complications. Methods 148 neonates (with gestational age of 28 to 34 weeks) with respiratory distress syndrome admitted to Imam Khomeini Hospital in Ahwaz in 2018 were enrolled in this clinical trial study. 74 neonates were assigned to duo positive airway pressure (NDUOPAP) group and 74 neonates to nasal continuous positive airway pressure (NCPAP) group. The primary outcome in this study was failure of N-DUOPAP and NCPAP treatments within the first 72 h after birth and secondary outcomes included treatment complications. Results there was not significant difference between DUOPAP (4.1 %) and NCPAP (8.1 %) in treatment failure at the first 72 h of birth (p = 0.494), but non-invasive ventilation time was less in the DUOPAP group (p = 0.004). There were not significant differences in the frequency of patent ductus arteriosus (PDA), pneumothorax, intraventricular hemorrhage (IVH) and bronchopulmonary dysplasia (BPD), apnea and mortality between the two groups. Need for repeated doses of surfactant (p = 0.042) in the NDUOPAP group was significantly lower than that of the NCPAP group. The duration of oxygen therapy in the NDUOPAP group was significantly lower than that of the NCPAP group (p = 0.034). Also, the duration of hospitalization in the NDUOPAP group was shorter than that of the NCPAP group (p = 0.002). Conclusions In the present study, DUOPAP compared to NCPAP did not reduce the need for mechanical ventilation during the first 72 h of birth, but the duration of non-invasive ventilation and oxygen demand, the need for multiple doses of surfactant and length of stay in the DUOPAP group were less than those in the CPAP group.

Acute Exacerbations

Abstract Background Hypercapnic exacerbations are severe complications of chronic obstructive pulmonary disease (COPD), characterized by negative impact on prognosis, quality of life and healthcare costs. The present standard of care for acute exacerbations of COPD is non-invasive ventilation; when it fails, the use of invasive mechanical ventilation is inevitable, but is associated with extremely poor prognosis. Extracorporeal circuits designed to remove CO2 (ECCO2R) may enhance the efficacy of NIV to remove CO2 and avoid the worsening of respiratory acidosis, which inevitably leads to failure of non-invasive ventilation. Although the use of ECCO2R for acute exacerbations of COPD is steadily increasing, solid evidence on its efficacy and safety is scarce, thus the need for a randomized controlled trial. Methods multicenter randomized controlled unblinded clinical trial including 284 (142 per arm) patients with acute hypercapnic respiratory failure caused by exacerbation of COPD, requiring respiratory support with NIV. The primary outcome is event free survival at 28 days, a composite outcome defined by survival in absence of prolonged mechanical ventilation, severe hypoxemia, septic shock and second episode of COPD exacerbation. Secondary outcomes are incidence of endotracheal intubation and tracheostomy, intensive care and hospital length-of-stay and 90-day mortality. Discussion Acute exacerbations of COPD represent a significant burden in terms of prognosis, quality of life and healthcare costs. Lack definite evidence despite increasing use of ECCO2R justifies a randomized trial to evaluate whether patients with acute hypercapnic acidosis not responsive to NIV should undergo invasive mechanical ventilation (with all serious related risks) or be treated with ECCO2R to avoid invasive ventilation but be exposed to possible adverse events of ECCO2R. Owing to its pragmatic nature, sample size and composite primary outcome, this trial aims at providing valuable answers to relevant questions for clinical treatment of acute exacerbations of COPD.

Background: Multiple non-invasive ventilation (NIV) modalities have been identified that may improve the prognosis of pediatric patients with acute lower respiratory infection (ALRI). However, the effect of NIV in children with ALRI remains inconclusive. Hence, this study aimed to evaluate the efficacy of various NIV strategies including continuous positive airway pressure (CPAP), high flow nasal cannula (HFNC), bilevel positive airway pressure (BIPAP), and standard oxygen therapy in children with ALRI and the need for supplemental oxygen.Methods: Embase, PubMed, Cochrane Library, and Web of Science databases were searched from inception to July 2021. Randomized controlled trials (RCTs) that compared different NIV modalities for children with ALRI and the need for supplemental oxygen were included. Data were independently extracted by two reviewers. Primary outcomes were intubation and treatment failure rates. Secondary outcome was in-hospital mortality. Pairwise and Bayesian network meta-analyses within the random-effects model were used to synthesize data. The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation framework.Results: A total of 21 RCTs involving 5,342 children were included. Compared with standard oxygen therapy, CPAP (OR: 0.40, 95% CrI: 0.16–0.90, moderate quality) was associated with a lower risk of intubation. Furthermore, both CPAP (OR: 0.42, 95% CrI: 0.19–0.81, low quality) and HFNC (OR: 0.51, 95% CrI: 0.29–0.81, low quality) reduced treatment failure compared with standard oxygen therapy. There were no significant differences among all interventions for in-hospital mortality. Network meta-regression showed that there were no statistically significant subgroup effects.Conclusion: Among children with ALRI and the need for supplemental oxygen, CPAP reduced the risk of intubation when compared to standard oxygen therapy. Both CPAP and HFNC were associated with a lower risk of treatment failure than standard oxygen therapy. However, evidence is still lacking to show benefits concerning mortality between different interventions. Further large-scale, multicenter studies are needed to confirm our results.Systematic Review Registration: https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=172156, identifier: CRD42020172156.

The Right

The benefit of non-invasive ventilation (NIV) in stable chronic obstructive pulmonary disease (COPD) remains controversial. However, there is increasingly more evidence of NIV efficiency, especially high-flow NIV. This review presents the old and the new evidence of NIV effectiveness in stable COPD, considering pathophysiological arguments for NIV in COPD. Guidelines, randomized controlled trials (RCTs) and crossover studies included in review and metaanalysis based on patient-reported outcomes (PROs) have been analyzed. The role of NIV in rehabilitation and in palliative care and the role of telemedicine in relation with NIV are still up for debate. Challenges in choosing the right device and the optimal mode of ventilation still exist. There are also discussions on the criteria for patient inclusion and on how to meet them. More studies are needed to determine the ideal candidate for chronic NIV and to explain all the benefits of using NIV.
