American and European society guidelines for atrial fibrillation management mostly agree on the utilization of rate and rhythm control strategies and the indications for oral anticoagulant (OAC) use. However, the level of adherence to guidelines in clinical practice may vary by region. In this study, data analysis from The Registry on Cardiac rhythm disorders assessing the control of Atrial Fibrillation (RECORD-AF) registry, an international registry in patients with newly diagnosed atrial fibrillation of1 year, shows that differences in practice exist between 3 regions, namely Western Europe, Eastern Europe, and North America. Data analyzed included major cardiovascular outcomes at 12 months, choice of rhythm versus rate control strategy and the use of OAC according to CHADS2 score between regions, and the cost incurred according to management strategy. In conclusion, there is preference for rhythm control strategy in Europe compared to North America without a significant impact on major cardiovascular outcomes; there is significant discrepancy in the use of OAC in Eastern Europe compared to the 2 other regions; and rate control was found to be more costly in all regions.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common inflammatory condition affecting the upper airways, with chronic symptoms such as nasal congestion, partial (hyposmia) or total (anosmia) loss of smell, anterior/posterior rhinorrhea, and mild facial pain.1 As many as 66% of patients with CRSwNP have comorbid asthma and suffer from more severe nasal obstruction, higher levels of lower airway inflammation, and worse asthma control than those without CRS.2, 3 Thus, patients with CRSwNP and comorbid asthma have a high disease burden, seriously impacting health-related quality of life (HRQoL).2, 3 Markers of type 2-mediated inflammation and antibody production (eg, IL-5, IgE) are associated with both CRSwNP and asthma pathogenesis.2
