Career Summary

Biography

Dr Scott is a Postdoctoral Research Fellow in the Priority Research Centre for Healthy Lungs. Her research examines the impact of obesity, exercise and nutrition in promoting or impeding inflammation and, ultimately, the effect this has on the pathogenesis of respiratory diseases. Dr Scott recently returned from The University of Queensland, where she completed a two year Postdoctoral Fellowship examining how exercise intensity impacts the inflammatory responses of adults with asthma.

A primary research goal of Dr Scott's is to conduct high quality research that is directly translatable into clinical practice. Her dietetic qualification position her uniquely to both devise and conduct this style of research. As an example, Dr Scott developed and tested a weight loss program tailored to obese adults with asthma, which found that a weight loss of 5-10% is associated with clinically important improvements in asthma control and asthma-related quality of life in 58% and 83% of patients respectively. Her weight loss recommendations have since been implemented into clinical practice guidelines published by the National Asthma Council Australia, with brochures distributed to health care providers and patients nationally. Dr Scott also developed a weight loss program and performed dietetic counselling in adults with chronic obstructive pulmonary disease (COPD) and, coupled with an exercise program, resulted in weight loss that coincided with highly significant improvements to health outcomes associated with mortality. She has also counselled patients with asthma to modify their dietary intake of antioxidants, which impacted their risk of experiencing an asthma exacerbation.

Dr Scott enjoys conducting cutting edge research. She was the first internationally to demonstrate an inflammatory mechanism driving the association between obesity and asthma, and this work has since been replicated by other research groups. As a continuation of this work, her weight loss program demonstrated that loss of fat tissue within the gynoid (hip) region is associated with a reduction to airway inflammation in females, while in males a reduced dietary intake of saturated fat is associated with a reduction to airway inflammation. This suggests that these changes are operating via different mechanisms in males versus females and, importantly, suggests dietetic intervention has beneficial effects for those with asthma.

Dr Scott's work demonstrates that exercise can be used as an adjuvant asthma therapy. She has shown that a 10-week exercise training program results in a highly significant 5-fold reduction in airway inflammation and improvements in asthma-related quality of life. She is currently investigating the impact of moderate-intensity and vigorous-intensity exercise on asthma, to establish which provides the greatest benefit for asthma outcomes. This research will provide vital evidence to help inform asthma management guidelines. An emerging theme, Dr Scott is also examining the impact of sex hormones on asthma. She has shown that asthmatic women using the oral contraceptive pill (OCP) have better asthma control and less inflamed airways when compared with those not using the OCP.

Research Expertise
Dr Scott completed a Bachelor Nutrition & Dietetics with Honours in 2006, worked as a Research Assistant, then completed a PhD in 2012. Her dietetic qualification and experience enables her to conduct specialised nutrition research. This has included the development and implementation of two highly successful weight loss programs. Dr Scott has worked clinically with respiratory research patients for more than 8 years and can perform a number of specialised techniques including sputum collection for the measurement of airway inflammation and dual-energy x-ray absorptiometry (DEXA) for the measurement of body composition and bone density. Dr Scott also has laboratory experience processing both blood and sputum samples, and performing ELISA's. Her work utilises specialised laboratory techniques including GC and HPLC for the measurement of fatty acids and antioxidants. as well as gene expression in blood and sputum samples.

Community Engagement and Peer Review
Dr Scott believes in pursuing opportunities that enable her to give back to the scientific community. From 2012-2014 she was Chair of the Nutrition Society of Australia (Newcastle Branch) and a National Committee Member. These roles required her to organise scientific meetings in the Newcastle region and provide input into the governance of the society at a national level. Since this time she has remained a Committee Member of her local group, both in Brisbane and upon her return to Newcastle. She has had media exposure including radio and newspaper interviews. Dr Scott was a contributing author for the most recent edition of "Better Living with COPD: A Patient Guide". She has acted as a reviewer for theses, NHMRC project grants, and is a regular reviewer (1-4/month) for top international journals including Thorax and European Respiratory Journal.

© 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.Background Both systemic inflammation and sex hormones have been proposed as potential mediators of the obese-asthma phenotype. The aim of this study was to examine the associations between sex hormones, oral contraceptive pill (OCP) use, systemic inflammation and airway inflammation in adults with asthma. Methods Obese (n = 39) and nonobese (n = 42) females and obese (n = 24) and nonobese (n = 25) males with asthma were recruited. Females were further categorized as reproductive-aged (<50 years old; n = 36) or older (>50 years old; n = 45). Thirteen (36.1%) reproductive-aged females were using the OCP. Participants had induced sputum cell counts measured and blood analysed for sex hormones and inflammatory markers. Results Obese reproductive-aged females had higher sputum %neutrophils than nonobese reproductive-aged females (45.4 ± 24.3% vs 27.5 ± 17.5%, P = 0.016); however, there was no difference in sputum neutrophils in obese compared with nonobese males (P = 0.620) or older females (P = 0.087). Multiple linear regression analysis found testosterone and OCP use to be negative predictors of sputum %neutrophils, while C-reactive protein and IL-6 were positive predictors of sputum %neutrophils. BMI and age were not significant predictors in the multivariate model. Reproductive-aged females using the OCP had significantly lower sputum %neutrophils than those not using the OCP (23.2 ± 12.6% vs 42.1 ± 23.8%, P = 0.015). Conclusions This study suggests that sex hormones and systemic inflammation may be mediating the obese-asthma phenotype. The observation that OCP use was associated with lower sputum %neutrophils in reproductive-aged females warrants further investigation.

Copyright © ERS 2015.Obese asthma is characterised by infiltration of adipose tissue by activated macrophages and mast cells. The aim of this study was to examine the age and sex effects of immunometabolism in obese asthma. Obese and non-obese asthmatic children and adults underwent spirometry, body composition assessment by dual energy X-ray absorptiometry and measurement of serum soluble CD163 (sCD163), tryptase, C-reactive protein (CRP) and other adipocytokines. Plasma CRP (p<0.01) and leptin (p<0.01) were elevated in obese asthmatic adults, and sCD163 (p=0.003) was elevated in obese asthmatic children. We observed significantly higher sCD163 in obese female children compared to obese female adults and male children, and higher CRP in obese female adults compared to obese male children and adults. Serum tryptase concentrations were not significantly different across age groups. sCD163 positively correlated with the proportion of android fat in obese female children (r=0.70, p=0.003) and obese female adults (r=0.65, p=0.003). In obese female children, sCD163 was inversely associated with forced expiratory volume in 1 s % predicted (r=-0.55, p=0.02) and was positively associated with the Asthma Control Questionnaire (r=0.57, p=0.02). Obese children with asthma have sex-specific macrophage activation, which may contribute to worse asthma control and lung function. The heterogeneous systemic inflammatory profile across age and sex suggests the existence of sub-phenotypes in obese asthma at the molecular level.

© 2015 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc. All rights reserved.Background Although exercise has multiple health benefits, relatively little attention has been paid to its potential therapeutic effects in those with asthma. Objective To examine the effects of acute exercise on inflammation in physically inactive and active adults with asthma. Methods Fourteen adults with asthma (n = 6 physically inactive, n = 8 physically active) completed (1) 30 minutes of moderate-intensity exercise on a treadmill and (2) 30 minutes of rest in random order, with 4 weeks between sessions. Exhaled nitric oxide (eNO) was measured before and after the intervention (0, 0.5, 1, 2, 4, and 24 hours). Blood inflammatory mediators were measured before and after the intervention (0, 2, and 24 hours). Results Physically inactive participants had a significant decrease in eNO 4 hours after exercise (-4.8 ppb, -6.4 to -0.5 ppb, P =.028), which was not observed in physically active participants (P =.362). Interluekin-1 receptor antagonist increased in the physically inactive group 2 hours after exercise, with this increase strongly correlated with the decrease in eNO at 4 hours (R = -0.685, P =.007) and 24 hours (R = -0.659, P =.014) after exercise. Interleukin-6 was increased significantly 2 hours after exercise in physically inactive participants. Blood neutrophils and nuclear factor erythroid 2-like 2 gene expression were increased 2 hours after exercise in the overall cohort. Conclusion This study demonstrates that acute moderate-intensity exercise is associated with decreased eNO in physically inactive adults with asthma and suggests that interluekin-1 receptor antagonist could have a role in mediating this effect. The attenuated response in physically active participants might be due to the sustained anti-inflammatory effects of exercise training. Future studies should investigate the impact of exercise intensity and exercise training on airway inflammation in those with asthma.

© 2014 Asian Pacific Society of Respirology.Background and objective While weight loss has been shown to reduce obesity-related comorbidity, many weight loss treatments fail. Factors that enhance weight loss success are unknown, particularly in those with asthma. The aim of the study was to identify patient characteristics that predict weight loss success in adults with asthma. Methods Baseline and change in asthma characteristics and eating behaviours were investigated for relationships with weight loss and fat loss using multiple linear regression, in 38 overweight and obese adults with asthma randomized to dietary, exercise or combined interventions targeting weight loss for 10 weeks. Results Mean ± standard deviation weight loss was 6.6 ± 5.1 kg. Greater %weight loss and %fat loss was achieved in those with poorer asthma-related quality of life at baseline ((rs = 0.398, P = 0.015) and (rs = 0.455, P = 0.005) respectively), with 1.7% greater absolute weight loss at week 10 corresponding to each one unit reduction in the asthma-related quality of life score at baseline. Furthermore, a lower baseline forced expiratory volume in 1 s/forced vital capacity correlated with greater weight loss (rs = 0.398, P = 0.015). Male sex was associated with a 3.6 kg greater weight loss (P = 0.087). Reducing emotional eating during the programme was associated with greater weight loss in women (rs = 0.576, P = 0.010). Conclusions This study demonstrates that individuals with more severe asthma at baseline are more successful in achieving weight loss, which could be a consequence of greater motivation and could be used as a motivational tool within the clinical setting. Gender tailoring of weight loss programmes may be useful to enhance weight loss success. Future studies are urgently needed to establish predictors of long-term weight loss maintenance in those with asthma. See Editorial, page 179 This study is the first to demonstrate that more severe asthma at baseline, male sex, and improvements in eating behaviours during weight loss are associated with greater weight loss success in overweight and obese adults with asthma. Our findings may inform the development of asthma-specific weight management guidelines.

Asthma is a chronic inflammatory disorder of the airways. The inflammatory response in asthma is heterogeneous. Allergen specific responses lead to activation of the acquired immune system, via a predominantly IL-5 mediated, eosinophilic pathway. Stimuli such as viruses and bacteria activate the innate immune system, via a predominantly IL-8 mediated, neutrophilic pathway. Asthma has also been demonstrated to involve a systemic inflammatory component. Glucocorticoids are the predominant pharmacological treatment used to control inflammation in asthma. However, compliance with medications can be compromised due to patient concerns about side effects. Hence dietary interventions that target the inflammatory response in asthma have great potential. Various aspects of dietary intake are known to modulate inflammation. Saturated fatty acids can induce an inflammatory response via activation of pattern recognition receptors. Omega-3 fatty acids can be anti-inflammatory, via mechanisms such as modification of eicosanoid production. Antioxidants can have anti-inflammatory effects as they scavenge free radicals, preventing activation of transcription factors including NF-¿B. Chronic excess energy intake can lead to obesity, which augments inflammation due to the release of inflammatory mediators by adipose tissue. Here we review the role of these dietary components in asthma. © 2014 Bentham Science Publishers.
