Randomized Controlled Trial
An Internet-Mediated Pedometer-Based Program Improves Health-Related Quality of Life Domains and Daily Step Counts in COPD: A Randomized Controlled Trial.
Low levels of physical activity (PA) are associated with poor outcomes in people with COPD. Interventions to increase PA could improve outcomes. ⋯ An Internet-mediated, pedometer-based walking program can improve domains of HRQL and daily step counts at 4 months in people with COPD.

There are currently > 230 million people in the world with asthma, and asthma attacks result in the hospitalization of someone every 7 min. The National Heart, Lung, and Blood Institute outlines four components of clinical practice guidelines for the diagnosis and management of asthma, which tend to take a biomedical focus: (1) measures of assessment and monitoring, obtained by objective tests, physical examination, patient history, and patient report, to diagnose and assess the characteristics and severity of asthma and to monitor whether asthma control is achieved and maintained; (2) education for a partnership in asthma care; (3) control of environmental factors and comorbid conditions that affect asthma; and (4) pharmacologic therapy. Many national guidelines include providing patients with asthma with (1) written action plans, (2) inhaler technique training, and (3) structured annual reviews. ⋯ There is a growing appreciation that a narrative approach with patients with asthma, which focuses on the illness experience and aims to enhance patient-clinician understanding, might improve self-care. We explore how a framework for clinicians to listen to patients' stories, developed from research on individuals with asthma, might enhance communication, improve patient-clinician relationship, and foster better patient self-care. The article closes with the implications of this approach for clinical practice and future research.

Despite massive investments in the development of novel treatments for heterogeneous diseases such as COPD, the resources spent have only benefited a fraction of the population treated. Personalized health care to guide selection of a suitable patient population already in the clinical development of new compounds could offer a solution. This review discusses past successes and failures in drug development and biomarker research in COPD, describes research in COPD phenotypes and the required characteristics of a suitable biomarker for identifying patients at higher risk of progression, and examines the role of extracellular matrix proteins found to be upregulated in COPD. Novel biomarkers of connective tissue remodeling that may provide added value for a personalized approach by detecting subgroups of patients with active disease suitable for pharmacologic intervention are discussed.

Multicenter Study Observational Study
Lung ultrasound-implemented diagnosis of acute decompensated heart failure in the Emergency Department - A SIMEU multicenter study.
Lung ultrasonography (LUS) has emerged as a noninvasive tool for the differential diagnosis of pulmonary diseases. However, its use for the diagnosis of acute decompensated heart failure (ADHF) still raises some concerns. We tested the hypothesis that an integrated approach implementing LUS with clinical assessment would have higher diagnostic accuracy than a standard workup in differentiating ADHF from noncardiogenic dyspnea in the ED. ⋯ The implementation of LUS with the clinical evaluation may improve accuracy of ADHF diagnosis in patients presenting to the ED.
