Effects of a pulmonary rehabilitation program on physical capacity, peripheral muscle function and inflammatory markers in asthmatic children and adolescents: study protocol for a randomized controlled trial

The Effects of Combined Respiratory Muscle and Exercise Training in Children with Bronchial Asthma: A Randomised Controlled Study

Objective

To investigate the effects of combined respiratory muscle and exercise training on inspiratory muscle strength, exercise capacity, spirometry measurements, asthma control the quality-of-life in children with asthma.

Methods

Fifty children with asthma, who were treated in children's hospital of Chongqing medical university in Chongqing between May and December 2021, were selected and randomly divided into a rehabilitation group and a control group by using a random number table. The control group was given routine drug treatment and health education while the rehabilitation group received a combination of respiratory muscle and exercise training on the basis of control group.

Results

After three months of treatment, the maximum inspiratory pressure, level of asthma control and quality-of-life in the rehabilitation group were significantly improved when compared with those in the control group (P<0.05); there were no significant differences in the 6-minute walking test and spirometry measurements (P>0.05). After three months of treatment, all outcome indicators in the rehabilitation group were significantly improved when compared to those before treatment (P<0.05). The mean value of maximum inspiratory pressure and some indices of spirometry measurements in the control group were significantly improved when compared to those before treatment (P<0.05).

Conclusion

Combining respiratory muscle and exercise training on the basis of the routine drug treatment and health education significantly improved inspiratory muscle strength, the level of asthma control and the quality-of-life in children with asthma. More research is needed to explore its role in asthma in the future.

Evaluation of a nurse-supervised rehabilitation programme on clinical features and systemic inflammation in Chinese children with asthma: A propensity score-matched analysis

AIMS

To evaluate whether a nurse-supervised rehabilitation programmes could improve respiratory functions and systematic inflammation in children with asthma.

BACKGROUND

Children with asthma always suffer from poor life quality, and physical training and pulmonary rehabilitation could be beneficial to asthma.

DESIGN

A retrospective, observational, single-centre cohort analysis.

METHOD

Baseline characteristics between the nurse-supervised rehabilitation programme and usual-care groups were matched by propensity-score matching (PSM) in a 1:1 ratio. We compared the lung function and inflammatory markers between groups.

RESULTS

Among 52 pairs of children, differences in lung function were improved in the nurse-supervised rehabilitation group compared with those in usual-care group, including the oxygen saturation, forced expiratory volume in 1 second, forced expiratory flow of 25%-75% and peak expiratory flow (all P < 0.05). Two asthma-related inflammatory markers (hypersensitive C-reactive protein and immunoglobulin E) also significantly decreased in the nurse-supervised rehabilitation group (both P < 0.001).

CONCLUSIONS

The results indicate that the nurse-supervised rehabilitation programme might be effective in improving symptom control, respiratory functions and systemic inflammation in children with asthma. The study suggests that the NSR for asthma merits further research.

Correlation and Predicted Equations of MIP/MEP from the Pulmonary Function, Demographics and Anthropometrics in Healthy Thai Participants aged 19 to 50 Years

Objective:

To identify the correlations and possible predicted equations of maximal inspiratory (MIP) and expiratory mouth pressure (MEP) values from pulmonary function test (PFT), demographics, and anthropometrics.

Methods:

This study involved 217 healthy participants (91 males and 126 females) aged 19 to 50 years. The PFT (forced vital capacity; FVC, forced expiratory volume in 1 second; FEV1, maximal mid-expiratory flow; MMEF, and peak expiratory flow; PEF) was performed by spirometry, whereas MIP and MEP were evaluated by a respiratory pressure meter. Pearson correlation and multiple linear regression, with the stepwise method, were used for statistical analysis.

Results:

The MIP and MEP had a significant positive correlation with weight, height, body mass index (BMI), and waist circumference. MIP had a significant positive correlation with FVC (%) and PEF (L/s and %), as well as a negative correlation with FEV1/FVC (ratio and %) and MMEF (%). Whereas, MEP showed a significant positive correlation with PEF (L/s and %) and negative correlation with FEV1/FVC (ratio and %) and MMEF (L/s). Finally, the predicted MIP and MEP equations were 103.988−97.70 × FEV1/FVC + 31.292 × Sex (male = 1 and female = 0) + 0.662 × PEF (%) and 47.384 + 3.603 × PEF (L/s)−9.514 × MMEF(L/s) + 30.458 × Sex (male = 1 and female = 0) + 0.534 × PEF (%), respectively.

Conclusion:

The respiratory muscle strengths can be predicted from the pulmonary function test, and gender data.

Designing a physical activity intervention for children with asthma: a qualitative study of the views of healthcare professionals, parents and children with asthma

OBJECTIVES

Qualitative methods were used to examine: (1) the attitudes of health professionals to promoting physical activity for children with asthma; (2) reasons why children with asthma are less active and (3) how a physical activity programme for children with asthma could be designed.

DESIGN

Semistructured interviews were conducted with health professionals, children with asthma and their parents between October 2015 and March 2016. Interviews were transcribed verbatim and thematically analysed.

SETTING

Primary and secondary care in Bristol (UK).

PARTICIPANTS

Interviews were held with 8 primary care practitioners (5 general practitioners, 2 nurse practitioners and 1 practice nurse), 9 parent-child dyads (2 fathers, 7 mothers, 6 sons, 3 daughters) of children aged 6-7 who had asthma and 4 secondary care professionals (2 respiratory consultants, 2 specialist nurses).

RESULTS

Health professionals reported that physical activity was beneficial for children with asthma and if managed appropriately, children with asthma could be as active as children without asthma. Current promotion of physical activity for children with asthma was limited and restricted by NHS staff time, access to inhalers at school and a lack of parental knowledge. Potentially important components of a new programme include parental education on the possibilities of activity for children with asthma and the difference between exercise-induced breathlessness and asthma symptoms. Other important elements include how to use inhalers as a preventive measure, coping with exacerbations and practical solutions (such as clearing sputum), managing transitions from warm to cold climates and general symptom control.

CONCLUSIONS

There is a need to build on current asthma programmes to increase the support for children with asthma to be physically active. Future programmes could consider working more closely with schools, increasing parental knowledge and providing children with practical support to help be physically active.

The school as a health promoter for children with asthma: The purpose of an education programme

BACKGROUND

Not only is asthma one of the leading causes of hospitalisation in children under 15 years and one of the main reasons for primary care outpatient visits, it also accounts for 13 million lost days of school annually, which can affect children's learning, integration at school and overall academic achievements.

MATERIAL AND METHODS

This review article highlights the important role of the school in helping children and adolescents to control and manage their asthma through integrated and coordinated actions of health professionals, school staff, family, and the community.

RESULTS

We recommended key elements for a multidisciplinary team asthma school programme that can be replicated and implemented especially in developing countries where children and adolescents are in a more disadvantaged environment.

CONCLUSION

This multidisciplinary asthma school intervention when demonstrated with efficacy can be applied in the context of the real world, where many children and families who need care the most currently do not receive it.
