Outcomes Associated with Corticosteroid Dosage in Critically Ill Patients with Acute Exacerbations of Chronic Obstructive Pulmonary Disease.
Studies evaluating corticosteroid (CS) dosing for patients hospitalized with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) have largely excluded patients admitted directly to the intensive care unit (ICU), and none have evaluated the effect of CS dosing regimens on mortality. ⋯ Two-thirds of patients admitted to the ICU with an AECOPD are treated with high doses of CS that are associated with worse outcomes and more frequent adverse effects. Lower dosage strategies should be encouraged for patients admitted to the ICU and the optimum dose should be determined through clinical trials.

Clinical TrialShould we view COPD Differently after ECLIPSE? A Clinical Perspective from the Study Team.
Chronic obstructive pulmonary disease (COPD) seems to be a heterogeneous disease with a variable course. ⋯ By following a large, well characterized cohort of patients with COPD over 3 years, we have a clearer picture of a heterogeneous disease with clinically important subtypes ("phenotypes") and a variable and not inherently progressive course. Clinical trial registered with www.clinicaltrials.gov (NCT00292552).

Randomized Controlled Trial
Pulmonary Function after Emergence on 100% Oxygen in Patients with Chronic Obstructive Pulmonary Disease: A Randomized, Controlled Trial.
During emergence from anesthesia, breathing 100% oxygen is frequently used to provide a safety margin toward hypoxemia in case an airway problem occurs. Oxygen breathing has been shown to cause pulmonary gas exchange disorders in healthy individuals. This study investigates how oxygen breathing during emergence affects lung function specifically whether oxygen breathing causes added hypoxemia in patients with chronic obstructive pulmonary disease. ⋯ In this experiment, the authors examined oxygen breathing during emergence-a widely practiced maneuver known to generate pulmonary blood flow heterogeneity. In the observed cohort of patients already presenting with pulmonary blood flow disturbances, emergence on oxygen resulted in deterioration of oxygen-related blood gas parameters. In the perioperative care of patients with chronic obstructive pulmonary disease, oxygen breathing during emergence from anesthesia may need reconsideration.

Multicenter Study Comparative Study
Prevalence, Treatment and Outcomes Associated with Obstructive Sleep Apnea Among Patients Hospitalized with Pneumonia.
OSA is associated with increased risks of respiratory complications following surgery. However, its relationship to the outcomes of hospitalized medical patients is unknown. ⋯ Among patients hospitalized for pneumonia, OSA is associated with higher initial rates of mechanical ventilation, increased risk of clinical deterioration, and higher resource use, yet a modestly lower risk of inpatient mortality.
