COPD exacerbations are a major cause of morbidity and mortality. Although inhaled corticosteroids (ICS) have a role as long-term treatment, their efficacy in exacerbations, particularly as an adjunct to systemic steroids, remains unclear. ⋯ Despite the known benefits of ICS in managing chronic COPD, we did not find an added value of ICS to systemic steroids in exacerbations. These results underscore the necessity for individualized treatment strategies and further research into the role of ICS in COPD exacerbations.

Observational Study
Reducing Airway Occlusion Time Without Losing Accuracy to Predict Successful Mechanical Ventilator Liberation During the Measurement of the Timed Inspiratory Effort Index.
In 2013, a new predictor of successful mechanical ventilation liberation named timed inspiratory effort (TIE) index was devised with the normalization of the maximum inspiratory pressure (obtained within 60 s of unidirectional airway occlusion) with the time at which the value was reached. The aim of this study was to verify whether the presence of a sequence of a certain number of inspiratory effort values between 30-60 s > 1.0 cm H2O/s could predict weaning success in a performance comparable to the TIE index. ⋯ The presence of a sequence of ≤ 4 inspiratory efforts > 1.0 cm H2O/s during the TIE index measurement was a reliable predictor of weaning success, which could allow timely interruption of the procedure and entail a substantial reduction in airway occlusion time.

Evidence-based practice is at the forefront of providing quality patient care by using the best available evidence and clinical expertise, while also considering patient needs and preferences for clinical decisions. However, evidence-based practice may not be consistently used even when the evidence supports the therapy. The purpose of this study was to assess the factors associated with the use of evidence-based practice among respiratory therapy faculty teaching in a large community college system and post-professional students enrolled in a university-based, respiratory therapy baccalaureate degree-advancement program. ⋯ Analysis of the results suggested that respiratory therapy faculty and students were knowledgeable and confident with regard to evidence-based practice but their use of evidence-based practice in clinical decisions was limited. Although the evidence-based practice knowledge, self-efficacy, and learning experiences had minimal influence on the use of evidence-based practice, the results of the study provide a foundation for future research.

Review Meta Analysis
Positive Airway Pressure and Metabolic Markers in Children With Obstructive Sleep Apnea.
Increasing evidence suggests an association between childhood obstructive sleep apnea (OSA) and metabolic syndrome, with more research available on the potential impacts of positive airway pressure (PAP) on metabolic markers in children. The purpose of this systematic review is to provide a systematic synthesis of the evidence on the effect of PAP use on metabolic markers in children with OSA. ⋯ Although evidence on effects of PAP on metabolic markers in children with OSA is encouraging, available literature is limited. Longitudinal studies are still required to further assess the long-term influence of PAP on metabolic and inflammatory markers, particularly in children with obesity.

Despite periodic changes in the clinical definition of ARDS, imaging of the lung remains a central component of its diagnostic identification. Several imaging modalities are available to the clinician to establish a diagnosis of the syndrome, monitor its clinical course, or assess the impact of treatment and management strategies. ⋯ This review will highlight several methods for lung imaging in ARDS, emphasizing basic operational and physical principles for the respiratory therapist. Advantages and disadvantages of each modality will be discussed in the context of their utility for clinical management and decision-making.
