For patients with acute symptomatic pulmonary embolism (PE), the Bova score classifies their risk for PE-related complications within 30 days after diagnosis. The original Bova score was derived from 2,874 normotensive patients with acute PE who participated in one of six prospective PE studies. ⋯ The Bova risk score accurately stratifies normotensive patients with acute PE into stages of increasing risk of PE-related complications that occur within 30 days of PE diagnosis.

The hypoxic ventilatory response (HVR) at sea level (SL) is moderately predictive of the change in pulmonary artery systolic pressure (PASP) to acute normobaric hypoxia. However, because of progressive changes in the chemoreflex control of breathing and acid-base balance at high altitude (HA), HVR at SL may not predict PASP at HA. We hypothesized that resting oxygen saturation as measured by pulse oximetry (Spo₂) at HA would correlate better than HVR at SL with PASP at HA. ⋯ We conclude that neither HVR at SL nor resting Spo₂ at HA correlates with elevations in PASP at HA.

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.

Observational Study
Economic Burden of Chronic Obstructive Pulmonary Disease by Presence of Comorbidities.
The morbidity and mortality associated with COPD exacts a considerable economic burden. Comorbidities in COPD are associated with poor health outcomes and increased costs. Our objective was to assess the impact of comorbidities on COPD-associated costs in a large administrative claims dataset. ⋯ Our analysis demonstrated that high resource use and costs were associated with COPD and multiple comorbidities.

A 22-year-old previously healthy woman was evaluated in pulmonary clinic for shortness of breath and cough that had been slowly progressive over 3 months. She otherwise reported being fully functional and attended her college graduation a week prior to evaluation. She had no history of smoking, illicit drug use, connective tissue disease, or noxious exposures.
