Review Meta Analysis
The Impact of Positive Expiratory Pressure Therapy on Hyperinflation in Patients With COPD.
Lung hyperinflation is a typical clinical feature of patients with COPD. Given the association between breathing at elevated lung volumes and the manifestation of severe debilitating symptoms, therapeutic interventions such as positive expiratory pressure (PEP) therapy and its variations (temporary, oscillatory) have been devised to mitigate lung hyperinflation. However, the efficacy of these interventions remains to be conclusively demonstrated. ⋯ In patients with COPD, the effect of PEP therapy on lung hyperinflation is unclear owing to the non-consistent change in lung hyperinflation outcomes, insufficient data, and lack of high-quality trials. Dyspnea and physical capacity might improve with PEP therapy.

Review Meta Analysis
Risk of Fracture and Osteoporosis in Patients With COPD and Inhaled Corticosteroids Treatment.
There are disputes whether inhaled corticosteroids (ICS) increase the incidence of fracture or osteoporosis among patients with COPD. The aim of this meta-analysis was to assess the effect of ICS treatment on the risk of fracture and osteoporosis in subjects with COPD. ⋯ ICS use did not increase the incidence of fracture or osteoporosis in subjects with COPD.

Objective: This study aimed to compare and rank the effects of aerobic exercise (AE), resistance training (RT), endurance training (ET), and high-intensity interval training (HIIT) in chronic obstructive pulmonary disease (COPD) by network meta-analysis (NMA). Methods: PubMed, Cochrane, Embase, and Web of Science were searched to identify randomized controlled trials investigating the effects of exercise training on COPD. The search period began on the date of database establishment and ended in April 8, 2023. ⋯ Conclusion: The findings of this study suggest that HIIT may be more effective than endurance exercise, resistance exercise, and AE in improving the 6MWD, FEV1, FEV1/FVC ratio, and SGRQ scores in patients with COPD. Additionally, ET may be better than resistance exercise, AE, and HIIT in improving FVC in COPD patients. However, due to the limited number of studies conducted on HIIT, more high-quality randomized controlled trials (RCTs) are required to verify these conclusions.

Review
Late Diagnosis of Foreign Body Aspiration in Adults: Case Series and Review of the Literature.
Tracheobronchial foreign body (FB) aspiration (FBA) is a life-threatening emergency mostly observed in childhood and advanced age. With early diagnosis, the FB can be removed using bronchoscopic methods without causing irreversible damage. ⋯ The findings of the present study demonstrate that subjects tended to forget the FBA, leading to insidious respiratory system symptoms, with recurrent infections. In cases with an endobronchial mass lesion image on thorax CT, clinicians should consider the possibility of FBA. Delayed diagnosis of both organic and inorganic FB may cause granulation tissue.

Mechanical ventilation is ubiquitous in critical care, and duration of ventilator liberation is variable and multifactorial. While ICU survival has increased over the last two decades, positive-pressure ventilation can cause harm to patients. Weaning and discontinuation of ventilatory support is the first step in ventilator liberation. ⋯ New tools such as diaphragmatic ultrasonography have begun to appear in the literature as a tool for outcome prediction. A number of systematic reviews with both meta-analysis and network meta-analysis that synthesize the literature on ventilator liberation have also been published in the last year. This review describes changes in performance, monitoring of spontaneous breathing trials, and evaluations of successful ventilator liberation.
