Methods: We conducted a retrospective study among 497 male patients with OSA on CPAP therapy. Participants with pretreatment Apnea-Hypopnea Index (AHI) data based on overnight polysomnographic recordings completed a questionnaire. Adherence data for CPAP therapy were collected using a smart card system. We classified CPAP use of ≥4 hours per night and ≥70% of nights as good adherence; other CPAP use was categorized as poor adherence. Logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for poor adherence to CPAP therapy in the hypertension and diabetes mellitus groups, compared with the no comorbidity group, adjusting for body mass index, duration of CPAP therapy, AHI, and Epworth Sleepiness Scale score.

Results: In the no comorbidity, hypertension, and diabetes mellitus groups, 43.4%, 44.7%, and 56.0%, respectively, had poor adherence to CPAP therapy. Being in the diabetes mellitus group was significantly associated with poor adherence to CPAP therapy (OR=1.86, 95% CI: 1.18-2.92, =0.007); there was no association for the hypertension group.

Conclusion: Our results indicate that comorbidity of diabetes mellitus is associated with poor adherence to CPAP therapy in male patients with OSA.

Noninvasive respiratory support following extubation in critically ill adults with obesity: a systematic review and network meta-analysis.

EClinicalMedicine

January 2025

Department of Anesthesia and Intensive Care Unit, Regional University Hospital of Montpellier, St-Eloi Hospital, University of Montpellier, Montpellier, CEDEX 5, France.

Background: Patients with obesity are at high-risk of extubation failure. Discrepancies were found in the results of recent randomized controlled trials (RCTs) regarding the roles of noninvasive ventilation (NIV), high flow nasal cannula (HFNC) and conventional oxygen therapy (COT) to prevent extubation failure in critically ill patients with obesity.

Methods: In this systematic review and network meta-analysis, we searched MEDLINE, Cochrane Center Register of Controlled Trials and Web of Science from 1 January 1998 to 1 July 2024 for RCTs evaluating noninvasive respiratory support therapies (NIV, HFNC, COT, NIV + HFNC) after extubation in critically ill adults with obesity.

Background And Objective: Helmet-Continuous Positive Airway Pressure (H-CPAP) is a non-invasive respiratory support that is used for the treatment of Acute Respiratory Distress Syndrome (ARDS), a severe medical condition diagnosed when symptoms like profound hypoxemia, pulmonary opacities on radiography, or unexplained respiratory failure are present. It can be classified as mild, moderate or severe. H-CPAP therapy is recommended as the initial treatment approach for mild ARDS.

Obstructive sleep apnea (OSA) is a prevalent sleep disorder linked to significant daytime sleepiness and mood disturbances. Continuous positive airway pressure (CPAP) therapy is the standard treatment for OSA, but its effects on mental health outcomes, are not well understood. This study aimed to evaluate the impact of CPAP on daytime sleepiness, depressive symptoms, and anxiety symptoms while assessing how improvements vary with age.

Background: Obstructive Sleep Apnea (OSA) and Excessive Daytime Sleepiness (EDS) are associated with increased Alzheimer's disease (AD) risk. Black and Hispanic subjects have a higher burden of AD, present with greater OSA symptom severity, and EDS than non-Hispanic whites. We present preliminary data supporting an innovative trial examining the impact of a novel OSA treatment paradigm on markers of (i) sleepiness related to cognition and (ii) AD progression, among Black and Hispanic subjects.

Purpose: Obstructive sleep apnea-hypopnea syndrome (OSAHS) is the most common sleep-related breathing disorder. Longer term, repeated episodes of hypercapnia and hypoxemia during sleep are associated with inflammatory and atherosclerosis-related factors. The aim of this study was to explore the effect of continuous positive airway pressure (CPAP) therapy on cerebral vasoreactivity and early atherosclerosis in patients with severe OSAHS.
