- Effects of a behaviour change intervention aimed at increasing physical activity on clinical control of adults with asthma: study protocol for a randomised controlled trial(2019) FREITAS, Patricia D.; XAVIER, Rafaella F.; PASSOS, Natalia F. P.; CARVALHO-PINTO, Regina M.; CUKIER, Alberto; MARTINS, Milton A.; CAVALHERI, Vinicius; HILL, Kylie; STELMACH, Rafael; CARVALHO, Celso R. F.Background: In adults with asthma, physical activity has been associated with several asthma outcomes. However, it is unclear whether changes in physical activity, measured via an accelerometer, have an effect on asthma control. The objective of the present study is, in adults with moderate-to-severe asthma, to investigate the effects of a behaviour change intervention, which aims to increase participation in physical activity, on asthma clinical control. Methods: This is a single-blind (outcome assessor), two-arm, randomised controlled trial (RCT). Fifty-five participants with moderate-to-severe asthma, receiving optimized pharmacological treatment, will be randomly assigned (computer-generated) into either a Control Group (CG) or an Intervention Group (IG). Both groups will receive usual care (pharmacological treatment) and similar educational programmes. In addition to these, participants in the IG will undergo the behaviour change intervention based on feedback, which aims to increase participation in physical activity. This intervention will be delivered over eight sessions as weekly one-on-one, face-to-face 40-min consultations. Both before and following the completion of the intervention period, data will be collected on asthma clinical control, levels of physical activity, health-related quality of life, asthma exacerbation and levels of anxiety and depression symptoms. Anthropometric measurements will also be collected. Information on comorbidities, lung function and the use of asthma medications will be extracted from the participant's medical records. Discussion: If successful, this study will demonstrate that, in adults with asthma, a behavioural change intervention which aims to increase participation in physical activity also affects asthma control.
- Identification of asthma phenotypes using cluster analysis(2018) FREITAS, Patricia D.; XAVIER, Rafaella F.; SILVA, Simone T. C. da; CARVALHO-PINTO, Regina M.; STELMACH, Rafael; CUKIER, Alberto; MARTINS, Milton A.; CARVALHO, Celso R. F.
- Identification of asthma phenotypes based on extrapulmonary treatable traits(2021) FREITAS, Patricia Duarte; XAVIER, Rafaella Franca; MCDONALD, Vanessa Marie; GIBSON, Peter Gerard; CORDOVA-RIVERA, Laura; FURLANETTO, Karina Couto; OLIVEIRA, Joice Mara de; CARVALHO-PINTO, Regina Maria; CUKIER, Alberto; STELMACH, Rafael; CARVALHO, Celso Ricardo FernandesAsthma is a heterogeneous and complex disease, and a description of asthma phenotypes based on extrapulmonary treatable traits has not been previously reported. The objective of this study was to identify and characterise clusters based on clinical, functional, anthropometrical and psychological characteristics in participants with moderate-to-severe asthma. This was a cross-sectional multicentre study involving centres from Brazil and Australia. Participants (n=296) with moderate-to-severe asthma were consecutively recruited. Physical activity and sedentary time, clinical asthma control, anthropometric data, pulmonary function and psychological and health status were evaluated. Participants were classified by hierarchical cluster analysis and the clusters compared using ANOVA, Kruskal Wallis and Chi-squared tests. Multiple logistic and linear regression models were performed to evaluate the association between variables. We identified four clusters: 1) participants with controlled asthma who were physically active, 2) participants with uncontrolled asthma who were physically inactive and more sedentary; 3) participants with uncontrolled asthma and low physical activity, who were also obese and experienced anxiety and/or depression symptoms; and 4) participants with very uncontrolled asthma who were physically inactive, more sedentary, obese and experienced anxiety and/or depression symptoms. Higher levels of sedentary time, female sex and anxiety symptoms were associated with increased odds of exacerbation risk, while being more active showed a protective factor for hospitalisation. Asthma control was associated with sex, the occurrence of exacerbation, physical activity and health status. Physical inactivity, obesity and symptoms of anxiety and/or depression were associated with worse asthma outcomes, and closely and inextricably associated with asthma control. This cluster analysis highlights the importance of assessing extrapulmonary traits to improve personalised management and outcomes for people with moderate and severe asthma.

- The Role of Exercise in a Weight-Loss Program on Clinical Control in Obese Adults with Asthma A Randomized Controlled Trial(2017) FREITAS, Patricia D.; FERREIRA, Palmira G.; SILVA, Aline G.; STELMACH, Rafael; CARVALHO-PINTO, Regina M.; FERNANDES, Frederico L. A.; MANCINI, Marcia C.; SATO, Maria N.; MARTINS, Milton A.; CARVALHO, Celso R. F.Rationale: Clinical control is difficult to achieve in obese patients with asthma. Bariatric surgery has been recommended for weight loss and to improve asthma control; however, the benefits of nonsurgical interventions have been poorly investigated. Objectives: To examine the effect of exercise training in a weight loss program on asthma control, quality of life, inflammatory biomarkers, and lung function. Methods: Fifty-five obese patients with asthma were randomly assigned to either a weight-loss program plus exercise (WL + E group, n = 28) or a weight-loss program plus sham (WL + S group, n = 27), where the weight-loss program included nutrition (caloric restriction) and psychological therapies. The WL + E group incorporated aerobic and resistance muscle training, whereas the WL + S group incorporated breathing and stretching exercises. Measurements and Main Results: The primary outcome was clinical improvement in asthma control over 3 months. Secondary outcomes included quality of life, lung function, body composition, aerobic capacity, muscle strength, and inflammatory/antiinflammatory biomarkers. After 3 months, 51 patients were analyzed. Compared with the WL + S group, the WL + E group demonstrated improved clinical control scores (median [25th to 75th percentile],-0.7 [-1.3 to -0.3] vs. -0.3 [-0.9 to 0.4]; P = 0.01) and greater weight loss (mean +/- SD, -6.8% +/- 3.5 vs. -3.1% +/- 2.6; P < 0.001) and aerobic capacity (median [25th to 75th percentile], 3.0 [2.4 to 4.0] vs. 0.9 [-0.3 to 1.3] ml O-2 X kg(-1) X min(-1); P < 0.001). These improvements in the WL + E group were also accompanied by improvements in lung function, antiinflammatory biomarkers, and vitamin D levels, as well as reductions in airway and systemic inflammation. Conclusions: Adding exercise to a short-term weight-loss program should be considered as a useful strategy for achieving clinical control of asthma in obese patients.
