Randomized Controlled Trial
Impact of Vasoactive Medications on ICU-Acquired Weakness in Mechanically Ventilated Patients.
Vasoactive medications are commonly used in the treatment of critically ill patients, but their impact on the development of ICU-acquired weakness is not well described. The objective of this study is to evaluate the relationship between vasoactive medication use and the outcome of ICU-acquired weakness. ⋯ In mechanically ventilated patients enrolled in a randomized clinical trial of early mobilization, the use of vasoactive medications was independently associated with the development of ICU-acquired weakness. Prospective trials to further evaluate this relationship are merited.

Effects of Exercise Training and CPAP in Patients With Heart Failure and OSA: A Preliminary Study.
Exercise and CPAP improve OSA. This study examined the effects of exercise in patients with heart failure (HF) and OSA. ⋯ In patients with HF and OSA, our preliminary results showed that exercise alone attenuated OSA and improved quality of life more than CPAP. In the landscape treatment of OSA in patients with HF, this analysis is the only randomized trial showing any treatment (in this case, exercise) that improved all the studied parameters. The results highlight the important therapeutic benefits of exercise, particularly because adherence to CPAP is low.

A 67-year-old man with a history of atrial fibrillation (AF) presented to his physician with symptoms of episodic, nighttime palpitations and excessive daytime sleepiness. Four years prior he underwent radiofrequency ablation after a confirmed diagnosis of AF with subsequent resolution of his palpitations. His palpitations returned approximately 1 year following the ablation. ⋯ Holter monitoring showed baseline sinus rhythm with multiple episodes of AF with rates of 75 to 169 beats/min. These events were all nocturnal and correlated with the symptom diary; episodes ranged from 45 min to 2 h. An echocardiogram showed normal left ventricular size and ejection fraction with a mildly enlarged right atrium (4.38 cm) and no evidence of pulmonary hypertension.

Observational Study
Effect of Acute Exacerbation of Idiopathic Pulmonary Fibrosis on Lung Transplantation Outcome.
Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) has an expected median survival of 3 months. Lung transplantation is a potentially lifesaving therapy for AE-IPF. However, the current knowledge of transplantation outcomes during AE-IPF is limited to a few small retrospective studies, reporting only 1-year post-transplantation survival. ⋯ Patients with IPF transplanted during AE-IPF had significantly worse short-term and long-term survival compared with patients transplanted during stable IPF. Patients with AE-IPF and very high LAS may not experience the survival advantage expected from lung transplantation.
