Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic lung disease with no clear etiology and few therapeutic options. Growth factors that act as mediators in the development of this disease might be important therapeutic targets. Nintedanib is a triple-tyrosine kinase inhibitor and a potent antagonist of growth factors such as platelet-derived growth factor, vascular endothelial growth factor, and basic fibroblast growth factor, and it is currently evaluated in clinical trials as a potential IPF therapy. ⋯ Observations from clinical trials, together with the preclinical data, suggest that nintedanib may become an important therapeutic option for individuals with IPF. High-dose nintedanib improved the quality of life, slowed the progression of lung fibrosis and the decline of lung function, and reduced the rate of exacerbations in individuals with mild and moderate IPF. This is a short review based on the available data (September 2013) on nintedanib.

Randomized Controlled Trial Comparative Study
Home Mechanical Ventilation for COPD: High-Intensity Versus Target Volume Noninvasive Ventilation.
High-intensity noninvasive ventilation (HI-NIV) is the most effective means of improving several physiological and clinical parameters in subjects with chronic hypercapnic COPD. Whether the newer hybrid mode using target tidal volume noninvasive ventilation (target V(T) NIV) provides additional benefits remains unclear. ⋯ Switching subjects from well-established HI-NIV to target V(T) NIV shows no clinical benefits in chronic hypercapnic COPD. In particular, sleep quality, the control of nocturnal hypoventilation, daytime hypercapnia, overnight ventilation patterns, subjects' tolerance, health-related quality of life, lung function, and exercise capability were all similar in subjects who underwent HI-NIV and target V(T) NIV. Nevertheless, target V(T) NIV might offer some physiological advantages in breathing pattern and might be beneficial in some individual patients.

Tracheal intubation is used to establish a secure airway in patients who require mechanical ventilation. Unexpected extubation can have serious complications, including airway trauma and death. Various methods and devices have been developed to maintain endotracheal tube (ETT) security. Associated complications include pressure ulcers due to decreased tissue perfusion. Device consideration includes ease of use, rapid application, and low exerted pressure around the airway. ⋯ Noncommercial airway holders exert less force on a patient's face than commercial devices. Airway stability is affected by the type of securing method. Many commercial holders allow for rapid but secure movement of the artificial airway from one side of the mouth to the other.

Comparative Study Observational Study
Effects of Bronchoalveolar Lavage on Refractory Mycoplasma pneumoniae Pneumonia.
This study prospectively evaluated the effect of early bronchoalveolar lavage (BAL) on refractory Mycoplasma pneumoniae pneumonia with radiologically proven large pulmonary lesions in children. ⋯ BAL appeared to be efficacious and well-tolerated treatment for refractory M. pneumoniae pneumonia with radiologically proven large pulmonary lesions, and early application of BAL may be more beneficial.

Observational Study
Evaluation of Adherence to Ambulatory Liquid Oxygen Treatment: Are Commercialized Dual-Pressure Transducers Helpful?
Treatment adherence is widely recognized as a critical problem in long-term oxygen therapy, particularly in ambulatory liquid oxygen (LOX) systems. Adherence-monitoring strategies may be helpful in managing patients. We evaluated subjects' adherence to LOX using VisionOx and compared these results with the subjects' own adherence diaries and self-reported perceptions of use. ⋯ Subjects overestimated adherence to LOX therapy (when measuring percent of days of use) compared to adherence diary and objective adherence monitoring. Because no significant difference was found comparing the diaries and VisionOx use, either may be helpful in clinical practice.
