We designed an Internet-Based Monitoring Systems (IBS) survey to facilitate monitoring of asthma symptoms and asthma exacerbations in the Severe Asthma Research Program (SARP). Our objective was to evaluate compliance with the IBS survey tool and to explore how data from an IBS tool can inform understanding of asthma phenotypes. ⋯ Active participation with an Internet-based symptom survey tool in patients with severe asthma is influenced by race, socioeconomic status, and asthma control. Among survey participants, a group with highly variable (labile) asthma control is identifiable as a specific subgroup with unmet treatment needs. The association of asthma lability, increased susceptibility to adverse asthma effects of cold and flulike illnesses, and metabolic dysfunction provides clues for potentially effective intervention strategies.

Most data on the clinical epidemiology of atrial fibrillation (AF) come from Western populations, and data for Asians are limited. We investigated the lifetime risk and projected number of AF among Asians. The annual risks of adverse events among patients with AF, time trends, and the risks compared with patients without AF were analyzed. ⋯ The burden of AF among Asian patients is increasing, with a lifetime risk of AF being 1 in 7. Optimized management of any associated comorbidities should be part of the holistic management approach for AF.

Failure to reliably diagnose ARDS may be a major driver of negative clinical trials and underrecognition and treatment in clinical practice. We sought to examine the interobserver reliability of the Berlin ARDS definition and examine strategies for improving the reliability of ARDS diagnosis. ⋯ The reliability of the Berlin ARDS definition is moderate, driven primarily by differences in chest imaging interpretation. Combining independent reviews by multiple clinicians or improving methods to identify bilateral infiltrates on chest imaging are important strategies for improving the reliability of ARDS diagnosis.

A 74-year-old white male farmer was admitted from his primary care physician's office after he presented with symptoms of cough productive of clear sputum, malaise, weakness, fatigue, and shortness of breath on exertion for 3 weeks. He was an ex-smoker with a history of hypertension, hyperlipidemia, and coronary artery bypass graft surgery. He did not report any chills, night sweats, or fevers during this presentation.
