Randomized Controlled Trial
Impact of Early Mobilization on Glycemic Control and ICU-Acquired Weakness in Critically Ill Patients Who Are Mechanically Ventilated.
ICU-acquired weakness (ICU-AW) has immediate and long-term consequences for critically ill patients. Strategies for the prevention of weakness include modification of known risk factors, such as hyperglycemia and immobility. Intensive insulin therapy (IIT) has been proposed to prevent critical illness polyneuropathy. However, the effect of insulin and early mobilization on clinically apparent weakness is not well known. ⋯ The duel effect of early mobilization in reducing clinically relevant ICU-AW and promoting euglycemia suggests its potential usefulness as an alternative to IIT.

Adaptive servoventilation (ASV) is an automated treatment modality used to treat many types of sleep-disordered breathing. Although default settings are available, clinician-specified settings determined in the sleep laboratory are preferred. Depending on the device, setting choices may include a fixed expiratory positive airway pressure (EPAP) level or a range for autotitrating EPAP; minimum and maximum inspiratory positive airway pressure or pressure support values; and type of backup rate algorithm or a selectable fixed backup rate. ⋯ Patients with opioid-induced sleep apnea, both obstructive and central, may also respond to ASV. The variability in response to ASV in a given patient along with the myriad choices of specific models and settings demand a high degree of expertise from the clinician. Finally, randomized controlled studies are needed to determine long-term clinical efficacy of these devices.

Randomized Controlled Trial
The efficacy of a brief motivational enhancement education program on continuous positive airway pressure adherence in obstructive sleep apnea: A randomized controlled trial.
Poor adherence to CPAP treatment in OSA adversely affects the effectiveness of this therapy. This randomized controlled trial (RCT) examined the efficacy of a brief motivational enhancement education program in improving adherence to CPAP treatment in subjects with OSA. ⋯ Subjects with OSA who received motivational enhancement education in addition to usual care were more likely to show better adherence to CPAP treatment, with greater improvements in treatment self-efficacy and daytime sleepiness.

Comparative Study
Epidemiology of asthma hospitalizations among American Indian and Alaska Native people and the general United States population.
Asthma, a common chronic disease among adults and children in the United States, results in nearly one-half million hospitalizations annually. There has been no evaluation of asthma hospitalizations for American Indian and Alaska Native (AI/AN) people since a previous study using data for 1988-2002. In this study, we describe the epidemiology and trends for asthma hospitalizations among AI/AN people and the general US population for 2003-2011. ⋯ Asthma hospitalization rates are decreasing for AI/AN people and the general US population despite increasing prevalence rates. AI/AN people experienced a substantially lower age-adjusted asthma hospitalization rate compared with the general US population. Although the rates for AI/AN infants and children 1 to 4 years of age have declined substantially, they remain higher compared with other age groups. Improved disease management and awareness should help to further decrease asthma hospitalizations, particularly among young children.

Spinal muscular atrophy (SMA) causes respiratory compromise that is difficult to assess in young children. The forced oscillation technique (FOT) is commercially available for children as young as 2 years of age and is nonvolitional. The aim of this study was to assess the usefulness of FOT in young children with SMA. ⋯ FOT is feasible in young children with SMA, with abnormal values of reactance and resistance on grouped data, worsening over 12 months. Xrs8 is related to respiratory tests used to monitor progress in SMA (FVC, PCF, AHI). Further research on the value of FOT in managing individuals is warranted.
