Cough augmentation techniques are taught by health-care providers to improve secretion clearance and to help prevent respiratory infections in children with neuromuscular disease. There is some evidence of the effectiveness of a manually assisted cough when applied by health-care providers. However, it is unknown whether parents and caregivers may also be effective in applying manually assisted cough. The aim of this study was to evaluate whether parents and caregivers are effective at applying a manually assisted cough to a child with neuromuscular disease after being taught by a health-care provider. ⋯ Parents and caregivers and health-care providers were ineffective at increasing cough peak flow in children with neuromuscular weakness when applying a manually assisted cough. A single training session was insufficient for a parent or caregiver to be able to apply a manually assisted cough effectively on his or her child with neuromuscular weakness. Further research is warranted to guide recommendations on how best to equip parents and caregivers with the skills to help manage children with neuromuscular disease.

Bronchiectasis leads to reduced functional capacity, which might have implications for physical activity. The impact of dyspnea and long-term oxygen therapy on physical activity has never been investigated in subjects with bronchiectasis. Based on these findings, specific strategies could be applied to allow individuals to be more active in their daily life. In this study we aimed to evaluate physical activity, the impact of dyspnea and long-term oxygen therapy on physical activity, and the determinants of physical activity in subjects with bronchiectasis. ⋯ Subjects with bronchiectasis exhibited reduced physical activity compared with healthy peers. Dyspnea has a negative impact on physical activity. Independent factors associated with physical activity included pulmonary function, dyspnea, functional capacity, and long-term oxygen therapy. These findings will guide strategies to enhance daily physical activity and to encourage subjects with bronchiectasis to be more active.

Randomized Controlled Trial
Effects of Mechanical Insufflation-Exsufflation on Airway Mucus Clearance Among Mechanically Ventilated ICU Subjects.
Few studies have evaluated the effects of mechanical insufflation-exsufflation (MI-E) in subjects on mechanical ventilation. Therefore, this study aimed to evaluate the effectiveness of MI-E on airway mucus clearance among mechanically ventilated ICU subjects. ⋯ Among the general ICU subjects receiving mechanical ventilation, use of an MI-E device during respiratory physiotherapy resulted in a larger amount of airway mucus clearance than respiratory physiotherapy alone. (ClinicalTrials.gov registration NCT03178565.).
