Asthma is a heterogeneous disease, usually characterized by chronic airway inflammation. Although inspiratory muscle training (IMT) and high-intensity interval training (HIIT) are beneficial for patients with asthma, controversies persist. Therefore, we aimed to investigate the effects of IMT and HIIT on lung function and respiratory muscle function of subjects with asthma. ⋯ IMT improved pulmonary function (FEV1%pred, FVC) and inspiratory muscle strength in subjects with stable asthma. Due to the small number of RCT studies included and the limited outcome measures involving HIIT, we were unable to draw conclusions about whether HIIT was beneficial in this meta-analysis. Moreover, clinical heterogeneity exists in different areas such as population and training programs; the above conclusions still need to be confirmed in future studies.

Noninvasive respiratory support (NRS) has been used to treat acute respiratory failure outside the ICU, but existing data have left many knowledge gaps for managing NRS in general wards. The primary objective of this study was to describe indications, duration of treatment, and outcomes of subjects treated with NRS outside the ICU. The secondary objective was to compare outcomes based on age < 80 or ≥ 80 y. ⋯ In a real-life setting outside the ICU, NIV and CPAP managed by a rapid response team with a daily visit in collaboration with ward staff highly experienced in NRS allowed us to treat the subjects without major complications. Post-discharge 1-year mortality was higher in the subjects ≥ 80 y old treated with NIV for acute hypercapnic respiratory failure.

Endotracheal intubation is a routinely performed procedure in the ICU. Whereas it is recognized that endotracheal intubation can result in laryngeal and tracheal injury, this study evaluated factors that may affect the incidence of posterior vocal cord ulcers (PVCUs). ⋯ Earlier tracheostomy placement was associated with reduced severity of vocal cord ulcer formation. The Kaplan-Meier model suggests that waiting for 14 d is likely too long and earlier placement of a tracheostomy, within a week, may decrease the morbidity of posterior vocal cord injury.
