Background: We sought to compare the accuracy of a newly developed childhood asthma score (CAS) with routine clinical assessment of respiratory status in children with acute asthma in predicting requirements for bronchodilator nebulization.
Methods: In this prospective observational study in children 2-18 y old with acute asthma, we evaluated the association between the CAS and routine clinical assessment as well as inter-rater agreement.
Results: The need for bronchodilator nebulization was assessed during 134 episodes of acute asthma in 47 children. Overall, bronchodilators were administered after routine clinical assessment in 74 episodes (55.2%). The median CAS was 2.5 (interquartile range of 2.0-3.0) for subjects who did not receive nebulization and 6.0 (interquartile range of 4.0-7.0) for subjects who did receive nebulization (P < .001). A CAS cutoff score of 4 yielded a sensitivity of 0.91 (95% CI 0.84-0.97) and a specificity of 0.77 (95% CI 0.66-0.87), with a positive predictive value of 0.83 (95% CI 0.75-0.91) and a negative predictive value of 0.87 (95% CI 0.78-0.96). In 79 episodes, the CAS was assessed by 2 independent raters. With a weighted kappa of 0.77, a good inter-rater agreement was obtained.
Conclusions: Using a cutoff value of 4, the newly developed CAS accurately predicts the requirement for bronchodilator nebulization in children with acute asthma without use of auscultative findings.

Lung fibrosis development utilizes alveolar macrophages, with mechanisms that are incompletely understood. Here, we fate map connective tissue during mouse lung fibrosis and observe disassembly and transfer of connective tissue macromolecules from pleuro-alveolar junctions (PAJs) into deep lung tissue, to activate fibroblasts and fibrosis. Disassembly and transfer of PAJ macromolecules into deep lung tissue occurs by alveolar macrophages, activating cysteine-type proteolysis on pleural mesothelium.

Introduction: Telemedicine is a health service that provides diagnosis, treatment evaluation, preventive medicine by using information and communication technologies between distant locations and aims to improve the health of the individuals and society. Social restrictions were applied during the pandemic process caused by coronavirus disease-2019 due to the virus called severe acute respiratory syndrome coronavirus-2 which emerged in late 2019. Through remote communication and information technologies in the followup of asthma patients, there is a need for studies on the effectiveness of using telemedicine methods was seen.

Similarly to acute intestinal helminth infection, several conditions of chronic eosinophilic type 2 inflammation of mucosal surfaces, including asthma and eosinophilic esophagitis, feature robust expansions of intraepithelial mast cells (MCs). Also the hyperplastic mucosa of nasal polyposis in the context of chronic rhinosinusitis, with or without COX1 inhibitor intolerance, contains impressive numbers of intraepithelial MCs. In this issue of the JCI, Derakhshan et al.

Transient receptor potential ankyrin 1 (TRPA1) molecule is an important type of transient receptor potential (TRP) cation channels, which can cause extracellular Ca to flow into cells after activation. TRPA1 plays an important role in acute and chronic pain, inflammation, kidney disease, cough and asthma, osteoarthritis, cardiovascular disease, obesity, diabetes, and other diseases. In this study, the expression of interleukin (IL)-1, IL-6, and IL-8 in periodontal ligament stem cells (PDLSCs) treated by lipopolysaccharide (LPS) and the effect of LPS on PDLSCS proliferation were detected.
