CPAP is the first-line treatment for moderate to severe OSA syndrome. Up to 25% of patients with OSA syndrome discontinue CPAP treatment due to side effects. Unintentional leakage and its associated annoying consequences are the most frequently reported adverse effects of CPAP. ⋯ Nasal obstruction, older age, higher BMI, central fat distribution, and male sex might be associated with an increased risk of unintentional leakage. Such leaks remain an important problem. Further studies are needed to improve the understanding of underlying clinical factors so that patients at risk of unintentional leaks may be identified and individualized solutions applied.

Review Meta Analysis
The Management of Benign Pleural Effusions using Indwelling Pleural Catheters - A Systematic Review and Meta-Analysis.
The indwelling pleural catheter (IPC), which was initially introduced for the management of recurrent malignant effusions, could be a valuable management option for recurrent benign pleural effusion (BPE), replacing chemical pleurodesis. The purpose of this study is to analyze the efficacy and safety of IPC use in the management of refractory nonmalignant effusions. ⋯ IPCs are an effective and viable option in the management of patients with refractory BPE. The quality of evidence to support IPC use for BPE remains low, and high-quality studies such as randomized controlled trials are needed.

Lung cancer screening using low-dose CT scanning reduces lung-cancer-specific and overall mortality in high-risk patients. A significant limitation of lung cancer screening is the false-positive rate. The American College of Radiology Lung Imaging Reporting and Data System (Lung-RADS) was designed to standardize reporting of low-dose lung cancer screening results and to decrease the false-positive rate without significantly compromising sensitivity. ⋯ It also does not have a specific reporting category for patients with isolated hilar and mediastinal adenopathy or pleural effusion in the absence of lung nodules. We report four such cases from our lung cancer screening program. We believe that this is a significant limitation of Lung-RADS and should be revised in its new version.

Randomized Controlled Trial
Postoperative Oxygen Therapy in Patients with Obstructive Sleep Apnea: A Randomized Controlled Trial.
Surgical patients with OSA are at increased risk for perioperative complications. Postoperative supplemental oxygen is commonly used, but it may contribute to respiratory depression in patients with OSA receiving opioids. The objective of the study is to investigate the effect of postoperative supplemental oxygen on arterial oxygen saturation (Sao2), sleep respiratory events, and CO2 level in patients with untreated OSA. ⋯ Postoperative supplemental oxygen was found to improve oxygenation and decrease the AHI without increasing the duration of apnea-hypopnea event or PtcCO2 level. A small number of patients had significant CO2 retention while receiving supplemental oxygen.

COPD is a highly debilitating disease that represents a substantial and growing health burden in women. There is increasing evidence for sex-related differences in COPD risk, progression, and outcomes. ⋯ Thus, a multifaceted approach is required to address COPD in women, including greater awareness, minimization of risk, and further elucidation of the sex-specific factors (biological and cultural) that affect risk, disease progression, and treatment success. This article reviews the current literature on the topic and provides suggestions for achieving better outcomes for the millions of women with COPD worldwide.
