Reference values for respiratory system impedance using impulse oscillometry in healthy preschool children

PurposeThe normal values for lung resistance and lung capacity of children, as determined by impulse oscillometry (IOS), are different for children of different ethnicities. However, reference values there is no available reference value for Korean preschool children have yet to be determined. The aim of the present study was to determine the normal ranges of IOS parameters in Korean preschool children.MethodsA total of 133 healthy Korean preschool children were selected from 639 children (aged 3 to 6 years) who attended kindergarten in Seongnam, Gyeonggi province, Korea. Healthy children were defined according to the European Respiratory Society (ERS) criteria. All subjects underwent lung function tests using IOS. The relationships between IOS value (respiratory resistance (Rrs) and reactance (Xrs) at 5 and 10 Hz and resonance frequency (RF)) and age, height, and weight were analyzed by simple linear and multiple linear regression analyses.ResultsThe IOS success rate was 89.5%, yielding data on 119 children. Linear regression identified height as the best predictor of Rrs and Xrs. Using stepwise multiple linear regressions based on age, height, and weight, we determined regression equations and coefficients of determination (R2) for boys (Rrs5=1.934-0.009×Height, R2=12.1%; Xrs5=0.774+0.006×Height-0.002×Age, R2=20.2% and for girls (Rrs5=2.201-0.012×Height, R2=18.2%; Xrs5=-0.674+0.004×Height, R2=10.5%).ConclusionThis study provides reference values for IOS measurements of normal Korean preschool children. These provide a basis for the diagnosis and monitoring of preschool children with a variety of respiratory diseases

Innovation and Reaction to Change in the Music Industry

There is a common misconception that the Napster era (1999-2001) caused record sales to plummet and pushed the music industry into a free fall. Select musicians, though, continue to adapt successfully to changes and create sustainable careers. In the music industry, change correlates closely with technological advancements, which have dictated (or disrupted) different modes of control exercised by the publisher, the record label, or the Performing Rights Society. Through my review of the careers of Elgar, Duke Ellington, Radiohead, and Zoe Keating, I analyze how musicians and managers in the 20th and 21st centuries have responded to a changing industry and consumer desires by adapting quickly and seeking profitable, innovative opportunities

Respiratory function in healthy Emirati children using forced oscillations

© 2018 Wiley Periodicals, Inc. Background: The forced oscillation technique (FOT) allows the quantification of respiratory function, does not require active cooperation and as such is ideally suited for use in young children. The application of the FOT in non-Caucasian populations is limited and it remains unclear if current reference ranges for the FOT in Caucasian children are appropriate for children in the Arabian Peninsula. This study explored the use of the FOT in healthy school-aged children in the United Arab Emirates (UAE). Methods: Lung function using FOT was assessed in healthy Emirati children aged 4-12 years. Using a validated questionnaires general medical and respiratory histories were obtained. Prediction equations for resistance (Rrs), reactance (Xrs), and area under reactance curve (AX) were calculated and compared to previous studies. Results: FOT was successfully obtained in 291 healthy Emirati children. Linear regression modelling including weight, height, age, and gender in transformed FOT outcomes demonstrated that height was the strongest predictor of FOT outcomes (P < 0.001). Using the equated prediction equation Z-scores were calculated. FOT outcomes in Emirati children did not match previously published reference equations in Caucasians children (P < 0.001). Conclusion: FOT measurements were feasible in Emirati school-children. New FOT reference equation in Emirati children were derived. FOT reference equation in Emirati children was different from published equations in Caucasians
