Randomized Controlled Trial
Comparison of lung expansion techniques on thoracoabdominal mechanics and incidence of pulmonary complications after upper abdominal surgery: a randomized and controlled trial.
Lung expansion techniques (LETs) are widely used to prevent postoperative pulmonary complications (PPCs). However, the effects of each of these techniques on thoracoabdominal mechanics and PPC incidence after abdominal surgery remain unclear. The objective of this study was to compare the effects of LET on pulmonary volumes, respiratory muscle activation, and PPC incidence after major, elective upper abdominal surgery. ⋯ LETs do not modify the changes on thoracoabdominal mechanics or prevent PPCs after abdominal surgery. The indiscriminate use of LETs should not be routinely prescribed to prevent PPCs; however, more studies are required to confirm our results and to change the standard practice.

Multicenter Study Clinical Trial Observational Study
Five-year Outcomes of Patients Enrolled in the Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension (PAH) Disease Management (REVEAL).
Pulmonary arterial hypertension (PAH) is a rare, severe disease characterized by worsening right-sided heart failure, decreasing functional status, and poor survival. The present study characterizes the 5-year survival in the United States of a new and previous diagnosis of PAH in patients stratified by baseline functional class (FC). The Registry to Evaluate Early and Long-term PAH Disease Management (REVEAL Registry) is a 55-center observational US registry of the demographics, disease course, and management of patients with World Health Organization (WHO) group 1 PAH. ⋯ Patient survival of advanced PAH remains poor at 5 years despite treatment advances. New York Heart Association FC remains one of the most important predictors of future survival. These observations reinforce the importance of continuous monitoring of FC in patients with PAH.

Multicenter Study
Dedicated severe asthma services improve healthcare utilisation and quality of life.
Systematic assessment of severe asthma can be used to confirm the diagnosis, identify comorbidities, and address adherence to therapy. However, the prospective usefulness of this approach is yet to be established. The objective of this study was to determine whether the systematic assessment of severe asthma is associated with improved quality of life (QoL) and health-care use and, using prospective data collection, to compare relevant outcomes in patients referred with severe asthma to specialist centers across the United Kingdom. ⋯ To our knowledge, this is the first time that a prospective study has shown that a systematic assessment at a dedicated severe asthma center is associated with improved QoL and asthma control and a reduction in health-care use and oral steroid burden.

Multicenter Study Observational Study
Outcomes in Critically Ill Patients with Systemic Rheumatic Disease: a multicenter study.
Patients with systemic rheumatic diseases (SRDs) may require ICU management for SRD exacerbation or treatment-related infections or toxicities. ⋯ In patients with SRDs, critical care management is mostly needed only in patients with a previously known SRD; however, diagnosis can be made in the ICU for 12% of patients. Infection and SRD exacerbation account for more than two-thirds of these situations, both targeting chiefly the lungs. Direct admission to the ICU may improve outcomes.

Randomized Controlled Trial
Response to Fluid Boluses in the Fluid and Catheter Treatment Trial.
Recent emphasis has been placed on methods to predict fluid responsiveness, but the usefulness of using fluid boluses to increase cardiac index in critically ill patients with ineffective circulation or oliguria remains unclear. ⋯ In this cohort of critically ill patients with ARDS who were previously resuscitated, the rate of fluid responsiveness was low, and fluid boluses only led to small hemodynamic changes.
