—Deploying home access points (AP) is hard. Untrained users typically purchase, install, and configure a home AP with very little awareness of wireless signal coverage and complex interference conditions. We envision a future of autonomous wireless network management that uses the Internet as an enabling technology. By leveraging a P2P architecture over(More)
The aim of this study was to investigate the relationship between air pollution and respiratory symptoms in young children. A total of 263 children at high risk of developing asthma or atopy were recruited antenatally and all respiratory symptoms experienced by the children were recorded by their parents for five years. Daily pollutant concentrations and(More)
BACKGROUND The forced oscillation technique (FOT) can be used in children as young as 2 years of age and in those unable to perform routine spirometry. There is limited information on changes in FOT outcomes in healthy children beyond the preschool years and the level of bronchodilator responsiveness (BDR) in healthy children. We aimed to create reference(More)
The aim of this study was to compare two different methods, tidal breathing (TB) and single-breath (SB), for measuring fractional exhaled nitric oxide (FENO) in infants. FENO was measured in 71 infants with either recurrent wheeze (n=32), recurrent cough (n=16) or no symptoms (healthy, n=23) using both methods. For TB measurements five breaths were(More)
ISSUE ADDRESSED There are moves to ban smoking in outdoor areas of pubs, restaurants and cafes. Some argue that this is unnecessary as exposure to second hand smoke (SHS) is minimal. The aim of this study was to determine potential exposure of patrons to SHS in outdoor areas of eating and drinking venues. METHODS Concentrations of fine particulate matter(More)
PURPOSE Respiratory function impacts on musical expression for wind/brass (W/B) musicians. Investigation of musicians' respiratory health to date has rarely progressed further than assessments of flow limitation through spirometry. This study aimed to compare W/B musicians' respiratory function to a non-wind/brass (NW/B) group with a comprehensive(More)
BACKGROUND The fractional concentration of nitric oxide (NO) in exhaled breath (FeNO) is increased in asthma. There is a general assumption that NO synthase (NOS) 2 in epithelium is the main source of NO in exhaled breath. However, there is no direct evidence to support the assumption and data from animal models suggest that non-inducible NOS systems have(More)
RATIONALE Progressive lung damage in cystic fibrosis (CF) starts in infancy, and early detection may aid preventative strategies. OBJECTIVES To measure lung function in infants with CF diagnosed by newborn screening and describe its association with pulmonary infection and inflammation. METHODS Infants with CF (n = 68, 6 weeks to 30 months of age) and(More)
RATIONALE Pulmonary inflammation, infection, and structural lung disease occur early in life in children with cystic fibrosis. OBJECTIVES We hypothesized that the presence of these markers of cystic fibrosis lung disease in the first 2 years of life would be associated with reduced lung function in childhood. METHODS Lung function (forced expiratory(More)
BACKGROUND Raised exhaled nitric oxide (Feno) levels have been associated with asthma. However, we have found that in children, Feno was increased in atopic children with increased airway responsiveness (AR), and this was independent of a diagnosis of asthma. STUDY OBJECTIVES The current study was designed to test the hypothesis that in adults there is no(More)
