Randomized Controlled Trial Comparative Study
Comparison of three cough-augmentation techniques in neuromuscular patients: mechanical insufflation combined with manually assisted cough, insufflation-exsufflation alone and insufflation-exsufflation combined with manually assisted cough.
Mechanical insufflation-exsufflation (MI-E), more commonly known as 'cough assist therapy', is a method which produces inspiratory and expiratory assistance to improve cough performances. However, other alternatives or combinations are possible. ⋯ Our results indicate that adding the MI-E device to MAC is unhelpful in patients whose PCF with an insufflation technique and MAC exceeds 5 liters/s. This is because the expiratory flow produced by the patient's effort and MAC transitorily exceeds the vacuum capacity of the MI-E device, which therefore becomes a transient load against the PCF.

Randomized Controlled Trial
Prospective randomized trial of bispectral index monitoring of sedation depth during flexible bronchoscopy.
The clinical benefits associated with the use of the bispectral index (BIS) to monitor the depth of sedation during flexible fiberoptic bronchoscopy (FFB) are questionable. ⋯ Using BIS to guide the depth of sedation during propofol sedation in patients undergoing FFB of relatively short duration offers no clinically significant advantages over conventional monitoring.

Chronic pulmonary aspergillosis (CPA) affects individuals with non-systemic or mildly systemic immunodepression or altered pulmonary integrity due to underlying disease. It has been reported with a variety of clinical and radiological patterns. The condition should be distinguished from simple aspergilloma and allergic bronchopulmonary aspergillosis as well as invasive aspergillosis in severely immunocompromised patients. ⋯ Life-threatening haemoptysis may be prevented by bronchial arteriography with embolisation. However, currently there are no documented treatment recommendations for CPA. This review provides an up-to-date practical overview of this condition, including a comprehensive update on diagnosis and management.

Indwelling pleural catheters (IPC) are now established as one of the major tools for the management of recurrent pleural effusions. Their traditional role, which saw them only as second line treatment for malignant effusions, has now expanded. ⋯ IPCs are relatively simple to insert and maintain, and theoretically allow patients to be managed entirely as an outpatient, meaning that they are likely to be cost-effective in the longer term. They can also dramatically improve the quality of life in patients who have typically needed lengthy hospital admissions or who have terminal malignant disease.

Randomized Controlled Trial
Impact of intelligent volume-assured pressure support on sleep quality in stable hypercapnic chronic obstructive pulmonary disease patients: a randomized, crossover study.
Noninvasive positive-pressure ventilation (NPPV) using intelligent volume-assured pressure support (iVAPS) combines volume- and pressure-preset NPPV and therefore uses a variation of inspiratory positive airway pressures. ⋯ Although sleep quality in hospital was not different between iVAPS and HI-NPPV, COPD patients with chronic hypercapnic respiratory failure reported a trend towards more restful sleep at home with iVAPS. In addition, nocturnal hypercapnia was effectively treated with iVAPS.
