The transtheoretical model has been successful in promoting health behavior change in general and clinical populations. However, there is little knowledge about the application of the transtheoretical model to explain physical activity behavior in individuals with non-cystic fibrosis bronchiectasis. The aim was to examine patterns of (1) physical activity and (2) mediators of behavior change (self-efficacy, decisional balance, and processes of change) across stages of change in individuals with non-cystic fibrosis bronchiectasis. ⋯ The pattern of physical activity across stages of change is consistent with the theoretical predictions of the transtheoretical model. Constructs of the transtheoretical model that appear to be important at different stages of change include decisional balance cons, substituting alternatives, and enlisting social support. This study provides support to explore transtheoretical model-based physical activity interventions in individuals with non-cystic fibrosis bronchiectasis.

Randomized Controlled Trial
Zinc Supplementation for One Year Among Children with Cystic Fibrosis Does Not Decrease Pulmonary Infection.
Children with cystic fibrosis may have a deficiency of micronutrients, including zinc, which may affect their susceptibility to infections. There is a paucity of data on zinc supplementation among children with cystic fibrosis. We hypothesized that a pharmacologic dose of zinc administered daily for 12 months would reduce the need for antibiotics by 50%. ⋯ We did not find any significant difference in the need for antibiotics, pulmonary function tests, hospitalization, colonization with Pseudomonas, or the need for antibiotics for children with cystic fibrosis receiving zinc supplementation of 30 mg/d.

Both the National Asthma Education and Prevention Program Expert Panel Report 3 and the 2015 Global Initiative for Asthma guidelines identify achieving and maintaining asthma control as goals of therapy, and they emphasize periodic assessment of asthma control once treatment is established. Accurate assessment of asthma control is difficult due to the complexity of asthma control and due to the limitations in the traditional methods of assessment, such as lung function tests, physician assessment, and patients' self-assessment. Relying solely on the role of lung function tests is insufficient to reflect the status of asthma control, since patients with asthma may have normal spirometry between exacerbations. ⋯ Similarly, it is not uncommon for patients to overestimate how well their asthma is controlled, and, therefore, they under-report asthma symptoms and fail to recognize the impact that asthma has on their daily life. As a result, several tools have been developed to quantify the level of asthma control, identify patients at risk, and evaluate the effect of asthma management. This review examines the commonly used asthma control assessment tools in terms of content, psychometric properties, methods of administration, limitations, and ability to reflect the overall status of asthma control, which can aid clinicians in selecting the most appropriate tool for their needs.

Multicenter Study Observational Study
Use and Outcomes of Noninvasive Ventilation for Acute Respiratory Failure in Different Age Groups.
The prevalence of chronic disease and do-not-intubate status increases with age. Thus, we aimed to determine characteristics and outcomes associated with noninvasive ventilation (NIV) use for acute respiratory failure (ARF) in different age groups. ⋯ NIV use and a do-not-intubate status are more frequent in subjects with ARF ≥ 65 y than in those <65 y, especially for subjects with cardiogenic pulmonary edema. However, NIV success and mortality rates were similar between age groups. (ClinicalTrials.gov registration NCT00458926.).

Comparative Study
Neonatal Transcutaneous Carbon Dioxide Monitoring-Effect on Clinical Management and Outcomes.
This work aimed to compare frequency of blood gas measurements per day of mechanical ventilation, occurrence of extreme blood gas CO2 values, and clinical outcomes among ventilated neonates managed with and without transcutaneous carbon dioxide (PtcCO2) monitors. This work also measures agreement between simultaneous PtcCO2 and blood gas CO2 measurements and ascertains factors that affect agreement. ⋯ Despite only moderate agreement between simultaneous PtcCO2 and blood gas measurements, PtcCO2 monitoring statistically decreased blood gas frequency among ventilated neonates without affecting the duration of mechanical ventilation or clinical outcomes at discharge. The clinical impact of this technology appears to be minimal.
