Multicenter Study Comparative Study
Differences in end-of-life care in the ICU across patients cared for by medicine, surgery, neurology and neurosurgery physicians.
Some of the challenges in the delivery of high-quality end-of-life care in the ICU include the variability in the characteristics of patients with certain illnesses and the practice of critical care by different specialties. ⋯ Patients cared for by neurology and neurosurgery attending physicians have higher family and nurse ratings of quality of dying than patients cared for by medicine attending physicians and have a different pattern of indicators of palliative care. Patients with surgery attending physicians had fewer documented indicators of palliative care. These findings may provide insights into potential ways to improve the quality of dying for all patients.

Obstructive Sleep Apnea and Coronary Plaque Characteristics.
Virtual histology intravascular ultrasound (VH-IVUS) is an intravascular imaging technique that enables the characterization of coronary plaques. We sought to determine the association between OSA and coronary plaque characteristics in patients presenting with coronary artery disease. ⋯ In patients presenting with coronary artery disease, moderate to severe OSA was independently associated with a larger total atheroma volume in the target coronary artery. Further studies on the effects of CPAP on total atheroma volume are warranted.

INCREASED RISK OF EXACERBATION AND HOSPITALIZATION IN SUBJECTS WITH AN OVERLAP PHENOTYPE: COPD-ASTHMA.
Several COPD phenotypes have been described; the COPD-asthma overlap is one of the most recognized. The aim of this study was to evaluate the prevalence of three subgroups (asthma, COPD, and COPD-asthma overlap) in the Latin American Project for the Investigation of Obstructive Lung Disease (PLATINO) study population, to describe their main characteristics, and to determine the association of the COPD-asthma overlap group with exacerbations, hospitalizations, limitations due to physical health, and perception of general health status (GHS). ⋯ The coexisting COPD-asthma phenotype is possibly associated with increased disease severity.

The objectives of this systematic review were to synthesize the literature on measures of activities of daily living (ADLs) that have been used in individuals with COPD and to provide an overview of the psychometric properties of the identified measures and describe the relationship of the disease-specific instruments with other relevant outcome measures for individuals with COPD and health-care use. ⋯ Although several ADLs instruments were identified, psychometric properties have only been reported in a few. Selection of the most appropriate measure should focus on the target construct (BADLs or IADLs or both), type of test (disease-specific vs generic and self-reported vs performance-based), depth of information obtained, and psychometric properties of the instruments. Given the relevance of ADLs to the lives of patients with COPD, its assessment should be more frequently incorporated as a clinical outcome in their management.

Guidelines recommend mediastinal lymph node sampling as the first invasive test in patients with suspected lung cancer with mediastinal lymphadenopathy without distant metastases, but there are no comparative effectiveness studies on how test sequencing affects outcomes. The objective was to compare practice patterns and outcomes of diagnostic strategies in patients with lung cancer. ⋯ Guideline-consistent care with mediastinal sampling first resulted in fewer tests and complications. We found three quality gaps: failure to sample the mediastinum first, failure to sample the mediastinum at all in patients with non-small cell lung cancer, and overuse of thoracotomy.
