Randomized Controlled Trial
Evaluation of a peer-led asthma self-management program and benefits of the program for adolescent peer leaders.
Asthma is the leading chronic condition in adolescents. Nonetheless, research efforts to address adolescent asthma morbidity by applying a developmentally appropriate self-management intervention have been limited. Recently a peer-led asthma self-management program has been developed and implemented for adolescents. The purpose of the study was to assess the acceptability of a peer-led asthma program for adolescents based on participant feedback and to examine the program's impact on asthma outcomes in peer leaders. ⋯ A peer-led asthma self-management program was successfully implemented and well received by adolescent learners. Asthma outcomes in peer leaders appear to have improved as a result of the program, although caution should be exercised in determining clinical meaningfulness, given the modest changes in mean scores. ClinicalTrials.gov registration NCT01161225.

Randomized Controlled Trial
Volume-time curve: an alternative for endotracheal tube cuff management.
Despite numerous studies on endotracheal tube cuff pressure (CP) management, the literature has yet to establish a technique capable of adequately filling the cuff with an appropriate volume of air while generating low CP in a less subjective way. The purpose of this prospective study was to evaluate and compare the CP levels and air volume required to fill the endotracheal tubes cuff using 2 different techniques (volume-time curve versus minimal occlusive volume) in the immediate postoperative period after coronary artery bypass grafting. ⋯ The volume-time curve technique was associated with a lower CP and a lower volume of air injected into the cuff, when compared to the minimal occlusive volume technique in the immediate postoperative period after coronary artery bypass grafting. Therefore, the volume-time curve may be a more reliable alternative for endotracheal tube cuff management.

Randomized Controlled Trial
Different tracheotomy tube diameters influence diaphragmatic effort and indices of weanability in difficult to wean patients.
To determine the effects of different tracheotomy tube sizes on diaphragm effort and weanability indices. ⋯ In tracheotomized difficult to wean subjects the decrease of the tracheotomy tube size was associated with an increased PTP(di), f/V(T), and TT(di), that were otherwise normal, using a higher diameter. The in vitro study showed that the resistances increased similarly for tracheotomy tube and endotracheal tube, decreasing the diameter and increasing the flows.
