Introduction: For patients with obstructive sleep apnoea (OSA) who are initially non-compliant with continuous (automatic) positive airway pressure (CPAP/APAP) therapy, a bilevel PAP (Spont/VAuto) therapy transition pathway is available to improve therapy adherence. The aim of this retrospective study was to compare PAP therapy usage data of patients with non-compliant OSA (ncOSA) on CPAP/APAP who were switched to bilevel PAP.
Methods: A PAP telemonitoring database was queried between 1 January 2015 and 31 July 2016 for eligible patients started on CPAP/APAP and non-CMS (United States Center for Medicare and Medicaid Services) compliant and switched to bilevel PAP within 90 days of starting CPAP/APAP therapy. PAP therapy data on all patients were compared before switch (CPAP/APAP) and after switch (VAuto/Spont).
Results: Of the 1496 patients with ncOSA identified, 30.3% used CPAP, 62.3% APAP, and 7.4% both APAP and CPAP before switching to a bilevel mode. 47.8% patients switched to Spont mode and 52.2% to VAuto mode. PAP usage significantly improved by 0.9 h/day (p<0.001) and all other device metrics (residual apnoea-hypopnoea index and unintentional mask leak) also improved after the switch. No patients had achieved US CMS criteria for compliance before the switch, and 56.8% did after.
Conclusion: This shows for the first time that there may be potential benefit from switching from CPAP/APAP to bilevel PAP for patients struggling with PAP adherence.

Effects of smoking cessation on individuals with COPD: a systematic review and meta-analysis.
Front Public Health

Department of Respiratory, Shandong Qianfoshan Hospital, Cheeloo College of Medicine, Shandong University, Jinan, China.
Objective: Despite smoking being a significant risk factor in the occurrence and progression of chronic obstructive pulmonary disease (COPD), no comprehensive analysis has been conducted to determine the potential benefits of smoking cessation for patients with established COPD or identify specific indicators that may be improved. The aim of our meta-analysis was to elucidate the positive impact of smoking cessation on COPD.
Methods: We conducted a comprehensive search of PubMed, EMBASE, Web of Science, Cochrane Library, CNKI, Wan Fang and VIP databases to identify studies that met our eligibility criteria from inception up to 1, May 2024.
Compliance to international guidelines and rational use of antibiotics in urinary tract infections in a country without national guidance: a cross-sectional study.
BMJ Open Qual

INSPECT-LB, Beirut, Lebanon.
Background: Urinary tract infections (UTIs) are among the most common bacterial infections, and appropriate antimicrobial therapy with agents that minimise resistance is crucial. Despite international concern, adherence to guidelines is still suboptimal. This study aims to determine the effect of the absence of national guidelines and the rate of conformity to international guidelines among physicians in antibiotic (ATB) prescriptions for the treatment of UTIs in adults and detect the factors that are associated with a higher rate of non-compliance.

Objective: This expert opinion presents provisional guidelines for addressing complications associated with Additively Manufactured Subperiosteal Jaw Implants (AMSJI®) in patients with severe maxillary atrophy. AMSJI®'s custom design, supported by finite element analysis (FEA), allows precise placement that avoids critical anatomical structures and minimizes complications relative to alternative solutions.
Materials And Methods: Data were gathered through firsthand experiences, direct communications, and insights from international workgroup meetings.
Pediatric Obstructive Sleep Apnea: Diagnostic Challenges and Management Strategies.

Pediatrics, Neoclinic Children Hospital, Jaipur, IND.
Pediatric obstructive sleep apnea (OSA) is a prevalent yet often underdiagnosed condition affecting 1-5% of children globally, with higher prevalence in populations such as those with Down syndrome and obesity. Characterized by recurrent upper airway obstruction during sleep, OSA can lead to serious health consequences, including neurocognitive deficits, behavioral issues, and cardiovascular complications. The diagnosis is complicated by symptom overlap with conditions like Attention-Deficit/Hyperactivity Disorder (ADHD) while polysomnography (PSG) remains the gold standard for diagnosis, access to this test is limited in many regions.
