Background: Short courses of adjunctive systemic corticosteroids are commonly used to treat acute urticaria and chronic urticaria flares (both with and without mast cell-mediated angioedema), but their benefits and harms are unclear.
Objective: To evaluate the efficacy and safety of treating acute urticaria or chronic urticaria flares with versus without systemic corticosteroids.
Methods: We searched the MEDLINE, EMBASE, CENTRAL, CNKI, VIP, Wanfang, and CBM databases from inception to July 8, 2023, for randomized controlled trials of treating urticaria with versus without systemic corticosteroids.
Nitric oxide (NO) is a ubiquitous signaling molecule that is critical for supporting a plethora of processes in biological organisms. Among these, its role in the innate immune system as a first line of defense against pathogens has received less attention. In asthma, levels of exhaled NO have been utilized as a window into airway inflammation caused by allergic processes.

Background: Pediatric asthma is associated with increased health services utilization, missed school days, and diminished quality of life. Children with asthma also report more frequent depressive and anxiety symptoms than children without asthma, which may further worsen asthma outcomes.
Objective: The current study investigated the relationship between depressive and anxiety symptoms and 4 asthma outcomes (asthma control, asthma severity, lung function, and asthma-related quality of life) in children (N = 205) with moderate to severe persistent asthma.
