Despite various treatment modalities, a large proportion of patients have asthma that remains uncontrolled. These patients remain at an increased risk of developing severe exacerbations, have a poor quality of life, and pose a high economic healthcare burden, with an estimated mean annual cost more than double that of patients with good symptom control. It is therefore important to accurately diagnose asthma and continually assess asthma control. ⋯ National and international guidelines provide long-term management strategies for these patients and recommend a stepwise approach for achieving and maintaining asthma control. Despite availability of a wide range of controller and reliever therapies, uncontrolled asthma remains a challenge and reflects the need for new therapeutic options. This review discusses current global guidelines for the assessment and management of asthma control and summarizes the broad spectrum of novel therapeutic agents currently under development for the treatment of asthma, including anticholinergics, chemoattractant receptor-homologous molecules expressed on T-helper 2 lymphocyte antagonists, and anti-interleukin (IL)-5, anti-IL-13, and anti-IL-4 agents.

Multicenter Study
Reactive hemophagocytic syndrome in adults: a retrospective analysis of 162 patients.
Current knowledge in reactive hemophagocytic syndrome mainly relies on single-center case series including a relatively small number of patients. We aimed to identify a multicenter large cohort of adult patients with reactive hemophagocytic syndrome and to describe relevant clinical and laboratory features, underlying conditions, and outcome. ⋯ In this large, multicenter study, hematologic malignancies are the main disease associated with hemophagocytic syndrome in adults. Early mortality is high, and outcome is influenced by the underlying disease.

Brain changes on magnetic resonance imaging (MRI) reflect accumulating pathology and have clinically disabling consequences, such as dementia. However, little is known on the relation of these MRI markers with daily functioning in nondemented individuals. We investigated whether structural and microstructural brain changes are associated with impairment in activities of daily living in a community-dwelling population. ⋯ In community-dwelling individuals, brain changes are associated with deterioration and incident impairment in daily functioning.

Incidence and prevalence of mitral stenosis is declining in the US. We performed this study to determine recent trends in utilization, complications, mortality, length of stay, and cost associated with balloon mitral valvuloplasty. ⋯ In a large cross-sectional study of balloon mitral valvuloplasty in the US, we have reported trends of decreasing overall utilization and increasing procedural complication rates and cost over a period of 13 years.

Clinical practice guidelines recommend 40-60 mg of prednisone equivalent for 10-14 days for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD). However, the amount of corticosteroid prescribed varies widely in clinical practice. Using the electronic health record, we implemented an evidence-based order set to standardize treatment of patients hospitalized with acute exacerbations of COPD. ⋯ Evidence-based electronic ordersets improve compliance with clinical practice guidelines and reduce the total dose of corticosteroid administered in patients hospitalized with acute exacerbations of COPD.
