Abstract
BACKGROUND Exhaled nitric oxide is a marker of airway inflammation. Air pollution induces airway inflammation and oxidative stress. Little is known about the impact of air pollution on exhaled nitric oxide in young infants. METHODS The Breathing for Life Trial recruited pregnant women with asthma into a randomised controlled trial comparing usual clinical care versus inflammometry-guided asthma management in pregnancy. Four hundred fifty-seven infants from the Breathing for Life Trial birth cohort were assessed at six weeks of age. Exhaled nitric oxide was measured in unsedated, sleeping infants. Its association with local mean 24-h and mean seven-day concentrations of ozone, nitric oxide, nitrogen dioxide, carbon monoxide, sulfur dioxide, ammonia, particulate matter less than 10 μm (PM10) and less than 2.5 μm (PM2.5) in diameter was investigated. The air pollutant data were sourced from local monitoring sites of the New South Wales Air Quality Monitoring Network. The association was assessed using a 'least absolute shrinkage and selection operator' (LASSO) approach, multivariable regression and Spearman's rank correlation. RESULTS A seasonal variation was evident with higher median exhaled nitric oxide levels (13.6 ppb) in warmer months and lower median exhaled nitric oxide levels (11.0 ppb) in cooler months, P = 0.008. LASSO identified positive associations for exhaled nitric oxide with 24-h mean ammonia, seven-day mean ammonia, seven-day mean PM10, seven-day mean PM2.5, and seven-day mean ozone; and negative associations for eNO with seven-day mean carbon monoxide, 24-h mean nitric oxide and 24-h mean sulfur dioxide, with an R-square of 0.25 for the penalized coefficients. These coefficients selected by LASSO (and confounders) were entered in multivariable regression. The achieved R-square was 0.27. CONCLUSION In this cohort of young infants of asthmatic mothers, exhaled nitric oxide showed seasonal variation and an association with local air pollution concentrations.

Abstract
BACKGROUND Individuals with borderline personality disorder (BPD) are at a substantial risk of harm to themselves and others, experience high levels of functional impairment and typically are high users of tertiary healthcare to address their mental health concerns. As indicators for BPD typically emerge in adolescence, a day therapy service in Bentley, Western Australia, Touchstone Child and Adolescent Mental Health Service (CAMHS), was developed as an intensive intervention for adolescents with indicators for BPD and its associated symptomology. Touchstone utilizes mentalization-based therapy (MBT) in a therapeutic community setting, where the current study sought to document the anecdotal outcomes using the data provided at Touchstone, to enable a greater understanding of this treatment approach for adolescents with indicators for BPD. METHOD Forty-six participants attended the Touchstone programme between 2015 and 2020. The programme involved 6 months of MBT (group and individual), occupational therapy, education and creative therapies. Measures of self-injury, mood and emergency department presentations were collected pre- and post-programme. RESULTS Results indicate that participants show a reduction in non-suicidal acts and thoughts, as well as a reduction in negative moods and feelings from pre-Touchstone to post-Touchstone. There is also a decrease in participant presentation to tertiary emergency departments for mental health concerns. CONCLUSIONS The current study shows evidence for the efficacy of Touchstone as an MBT therapeutic community intervention to reduce symptoms of emerging BPD and effectively reduce presentations to emergency departments for mental health presentations, alleviating pressure on tertiary hospitals and reducing economic impact of adolescents within this demographic.
