Longitudinal study on peak expiratory flow monitoring and its impact on quality of life in childhood asthma

Objective To evaluate the impact of peak expiratory flow (PEF) monitoring using a smart peak flow (SPF) device on the quality of life (QoL) and satisfaction among children with asthma. Methods This 3-month prospective cohort study enrolled 71 children aged 7 to 17 years with physician-diagnosed asthma. Participants used the SPF device twice daily, with measurements recorded automatically. Quality of life was assessed using the Pediatric Asthma Quality of Life Questionnaire (PAQLQ), and asthma control was assessed using the Asthma Control Test (ACT) or Childhood Asthma Control Test (C-ACT). Adherence to PEF measurements and satisfaction with the device were evaluated. Results Seventy-one children (mean age 11.4 years) completed the study. Adherence to twice-daily PEF measurements decreased significantly over three months (from 50.0% at 1 month to 39.9% at 3 months, p < 0.001). Children with good adherence (38.0%) showed significant improvements in PAQLQ scores, while those with poor adherence (62.0%) did not. COVID-19 infection resulted in a significant decrease in %PEF rate and increased peak flow variability. Despite device-related issues, overall satisfaction was high (85.19% for good adherence users vs. 88.64% for poor adherence users, p = 0.671). Conclusion Regular PEF monitoring improves QoL in children with asthma by enabling early detection of symptom changes and better management. However, maintaining adherence to regular PEF monitoring is challenging. Further research with control groups is needed to validate these findings.

Virtual care for paediatric asthma: A randomized controlled trial.

This work aims to investigate whether virtual care can improve clinical outcomes for children with asthma, similar to face-to-face specialty care. The study used a randomized controlled trial design, with participants allocated to either a virtual care group (n = 47) or a control group (n = 50) using simple randomization. The study was conducted from March to August 2021, and a sample of 97 children with asthma was recruited. Children in the virtual care group received online training in four modules within the first month and support through virtual meetings and phone or video calls, while the control group received standard care. The primary outcome of the study was the Asthma Control Test and Child Asthma Control Test. The virtual care group had significantly better outcomes than the control group in terms of C-ACT scores for children aged 7-11 years, fewer days under 80% of the optimum level of peak expiratory flow, lower peak expiratory flow variability, fewer rescue medication uses, and more symptom-free days. The virtual care group also had a lower number of unscheduled hospital visits and a greater improvement in quality of life compared with the control group. This study demonstrated that virtual care can improve disease management and quality of life for children with asthma.

WPŁYW ADENOTONSILLEKTOMII NA KONTROLĘ ASTMY U PACJENTÓW PEDIATRYCZNYCH – PRZEGLĄD SYSTEMATYCZNY

IntroductionThis systematic review investigates the influence of adenotonsillectomy (AT) on asthma control in pediatric patients.Material and methodsA literature review from 2000 to 2023 based on the databases PubMed, the Cochrane Library, and Web of Science. The analysis is distilled down to four studies that revealed positive outcomes in asthma control as gauged by the Asthma Control Test (ACT), the Childhood Asthma Control Test (C-ACT), clinical outcomes, and asthma-related chitinase levels.ResultsThe four studies consistently demonstrated improved asthma control postoperatively in terms of improved ACT scores, reductions in acute asthma exacerbations, emergency room visits, hospitalisations, and medication usage. Notably, the correlation between improved asthma control and decreased chitinase activity suggests that AT has an impact on molecular markers associated with asthma.ConclusionsThe findings underline the potential benefits of AT in pediatric asthma management. However, the limitations of this study include a small number of studies and potential biases related to asthma’s natural course and seasonal variations. While the review provides evidence for the positive impact of AT on asthma control, further research with longer follow-up periods, case-matched controls, and consideration of seasonal factors is recommended.

The complex link between sleep-disordered breathing and asthma control in pediatric patients: A cross-sectional study

BackgroundIn children, asthma and sleep-disordered breathing (SDB) may affect quality of life (QoL), and SDB may complicate asthma management. ObjectiveTo evaluate the prevalence of SDB, its association with asthma control, and risk factors associated with SDB in a cohort of asthmatic children. The effects of asthma control and SDB on QoL were also investigated. MethodsWe consecutively recruited asthmatic children referred to our Pulmonology Service from December 1, 2022 to May 31, 2023. Data on anthropometrics, respiratory function, and allergies were collected. The prevalence of SDB was assessed by the Pediatric Sleep Questionnaire (PSQ). Asthma control status was assessed by the Childhood Asthma Control Test (C-ACT), while QoL was evaluated by the Pediatric Quality of Life Inventory (PedsQL) questionnaire. Factors associated with SDB were analyzed. ResultsA total of 78 asthmatic children aged 5–12 years were included. SDB was found in 37.2% of them, with a higher prevalence in children with uncontrolled versus well-controlled asthma (60.1% vs. 27.3%; p-value = 0.005). The C-ACT score was significantly lower in SDB-positive versus SDB-negative group, and uncontrolled asthma (C-ACT ≤19) was associated with a 4.15-fold increased risk of SDB. The PedsQL score was significantly lower in asthmatic children with than without SDB and was associated with lower SDB risk. SDB increased the risk of uncontrolled asthma in children, and asthmatic children with SDB had lower QoL. ConclusionIn asthmatic children, SDB affects both asthma control and QoL. Children with uncontrolled asthma should be referred for polysomnography to identify a possible underlying SDB.

Effects of Family-Supported Healthcare on Children with Asthma.

Healthcare is essential for asthma control, however, whether family-supported healthcare improves therapeutic effects in childhood asthma remains unclear. The enrolled patients were randomly divided into control and intervention groups. The pulmonary function was evaluated by forced expiratory volume in 1 s as a percentage of forced vital capacity (FEV1/FVC) and fractional exhaled nitric oxide (FeNO). Asthma control and life quality were assessed via a childhood asthma control test and pediatric asthma quality of life questionnaire. Inflammatory cytokines interleukin-6 (IL-6) and interleukin-17 (IL-17) were determined by enzyme-linked immunosorbent assay. No significant differences existed in the basic characteristics of asthma children and their parents among two groups. The increase of FEV1/FVC was higher in the intervention group versus the control group (76.47 ± 10.76% vs 69.76 ± 8.88%, p = 0.001 at the time of post-intervention), and the decrease of FeNO was greater in the intervention group (30.43 ± 6.85 bbp vs 35.64 ± 6.62 bbp, p = 0.003 at the time of post-intervention). Family-supported healthcare highly improved asthma control and quality of life in childhood asthma post-treatment. Meanwhile, the inflammatory cytokines IL-17 (118.14 ± 25.79 pg/mL in intervention group vs 142.86 ± 28.68 pg/mL in control group, p = 0.004 at the time of post-intervention) and IL-6 (103.76 ± 23.11 pg/mL in intervention group vs 119.73 ± 22.68 pg/mL in control group, p = 0.009 at the time of post-intervention) significantly decreased by family-supported healthcare intervention. Importantly, acute exacerbation (80.8% in intervention group vs 95.7% in control group, p = 0.030) and rehospitalization cases (88.5% in intervention group vs 100% in control group, p = 0.028) also decreased by family-supported healthcare intervention. Family-supported healthcare improves pulmonary function and quality of life while alleviates inflammation, acute exacerbation, and rehospitalization in childhood asthma post-routine treatment.

The effect of motivational interviewing techniques on the knowledge level of asthma control among mothers of children with allergic asthma

PurposeThis study aims to evaluate the effect of education given with motivational interviewing techniques on mothers of children with allergic asthma aged 4–11 years on asthma control and knowledge level. MethodsThe research was designed according to the CONSORT checklist with a randomized controlled design. 76 participants were randomly assigned to either an intervention (n = 38) or control group (n = 38). The intervention group received asthma education utilizing motivational interviewing techniques from a pediatric nurse. The control group received no further education. The Childhood Asthma Control Test and Asthma Knowledge Level Questionnaire were used to collect data. The control group received only education at the time of discharge. ResultsThe mothers' asthma control and asthma knowledge scores in the experimental group were significantly higher than in the control group (p < 0.001). In the experimental group, asthma control scores increased from 14.29 ± 4.27 to 21.37 ± 1.57 after education. The mean score of the asthma knowledge score increased from 54.74 ± 10.89 to 73.47 ± 7.17 after intervention. ConclusionsThe study showed that education using motivational interviewing techniques for mothers of children with allergic asthma increased their knowledge and positively affected asthma control. Implications to practiceEducation is important in improving mothers' knowledge about allergic asthma. Asthma education using motivational interviewing techniques should be provided when their children are newly diagnosed. Education practices should be implemented as a policy in hospitals and pediatric clinics, and nurses should be supported in ensuring the implementation of education practices.

Asthma control associated with anxiety and depression in asthmatic children following post-acute COVID-19.

Poor asthma control may adversely affect mental health. Our study investigates the correlation between inadequate asthma control, exhaled nitric oxide (FENO) levels, and anxiety and depression among pediatric asthma patients with COVID-19. This prospective case-control study enrolled 520 asthmatic children (8-15 years), including 336 patients diagnosed with COVID-19 after rapid antigen testing at home and 184 age-matched asthmatic patients without COVID-19 infection. FENO and spirometry were performed 1 month after COVID-19 infection. Scores for Child Anxiety-Related Disorders (SCARED) and depression screen derived from Patient Health Questionnaire-9 (PHQ-9) to assess their mental health status. Childhood asthma control test (C-ACT), FENO levels, and spirometry were correlated with the SCARED and PHQ-9 questionnaires. SCARED subscales, including generalized anxiety disorder, social anxiety disorder, school avoidance, and depression scores from PHQ-9, exhibited a significant increase in asthmatic patients diagnosed with COVID-19 (p < .05). Among asthmatic children with SARS-CoV-2 infection, the poor asthma control group exhibited the highest SCARED and PHQ-9 measurements (p < .01). Multiple linear regression analysis indicated that reduced C-ACT scores and elevated FENO levels in asthmatic children with COVID-19 were significant risk factors for both anxiety and depression scores (p < .05). Lower C-ACT scales were associated with high scores of SCARED (r = -0.471) and PHQ-9 (r = -0.329) in asthmatic children (p < .001). The current study emphasizes the need for healthcare professionals to closely monitor asthma control in asthmatic children to prevent heightened risks of depression and anxiety during the ongoing COVID-19 pandemic.

Risk factors of sleep-disordered breathing and poor asthma control in children with asthma

BackgroundSleep-disordered breathing (SDB) may lead to poor asthma control in children.ObjectiveTo identify risk factors of SDB in children with asthma and assess its impact on asthma control.MethodsIn this cross-sectional study, we collected data of outpatients with asthma at the Children’s Hospital of Chongqing Medical University from June 2020 to August 2021. The Pediatric Sleep Questionnaire—Sleep-Related Breathing Disorder and the age-appropriate asthma control tests Childhood Asthma Control Test and Test for Respiratory and Asthma Control in Kids were completed.ResultsWe enrolled 397 children with a male-to-female ratio of 1.7:1 and a mean age of 5.70 ± 2.53 years. The prevalence of SDB was 21.6%. Allergic rhinitis (odds ratio OR = 3.316), chronic tonsillitis (OR = 2.246), gastroesophageal reflux (OR = 7.518), adenoid hypertrophy (OR = 3.479), recurrent respiratory infections (OR = 2.195), and a family history of snoring (OR = 2.048) were risk factors for the development of combined SDB in children with asthma (p < 0.05). Asthma was poorly controlled in 19.6% of the children. SDB (OR = 2.391) and irregular medication use (OR = 2.571) were risk factors for poor asthma control (p < 0.05).ConclusionsAllergic rhinitis, chronic tonsillitis, gastroesophageal reflux, adenoid hypertrophy, recurrent respiratory infections, and a family history of snoring were independent risk factors for the development of SDB in children with asthma. SDB and irregular medication use were independent risk factors for poor asthma control.

Nasal oxidative stress mediating the effects of colder temperature exposure on pediatric asthma symptoms.

Colder temperature exposure is a known trigger for pediatric asthma exacerbation. The induction of oxidative stress is a known pathophysiologic pathway for asthma exacerbation. However, the role of oxidative stress in linking colder temperature exposure and worsened pediatric asthma symptoms is poorly understood. In a panel study involving 43 children with asthma, aged 5-13 years old, each child was visited 4 times with a 2-week interval. At each visit, nasal fluid, urine, and saliva samples were obtained and measured for biomarkers of oxidative stress in the nasal cavity (nasal malondialdehyde [MDA]), the circulatory system (urinary MDA), and the oral cavity (salivary MDA). Childhood Asthma-Control Test (CACT) was used to assess asthma symptoms. When ambient daily-average temperature ranged from 7 to 18 °C, a 2 °C decrement in personal temperature exposures were significantly associated with higher nasal MDA and urinary MDA concentrations by 47-77% and 6-14%, respectively. We estimated that, of the decrease in child-reported CACT scores (indicating worsened asthma symptoms and asthma control) associated with colder temperature exposure, 14-57% were mediated by nasal MDA. These results suggest a plausible pathway that colder temperature exposure worsens pediatric asthma symptoms partly via inducing nasal oxidative stress. The role of oxidative stress in linking colder temperature exposure and worsened asthma symptoms is still poorly understood. Lower temperature exposure in a colder season was associated with higher nasal and systemic oxidative stress in children with asthma. Nasal MDA, a biomarker of nasal oxidative stress, mediated the associations between colder temperature exposures and pediatric asthma symptoms. The results firstly suggest a plausible pathway that colder temperature exposure worsens pediatric asthma symptoms partly via inducing oxidative stress in the nasal cavity.

Elevated Saliva Pepsin Concentration as a Risk Factor for Asthma in Children with Allergic Rhinitis: A Preliminary Study.

This study aimed to explore whether saliva pepsin concentration (SPC) could be regarded as a risk factor for the occurrence and unfavorable control of asthma in children with allergic rhinitis. A prospective study was conducted on a group of 20 consecutive children newly diagnosed with allergic rhinitis and asthma (referred to as the asthma group). All these children underwent fractional exhaled nitric oxide (FeNO) measurement, lung function tests, and assessment of asthma control using the 7-item Childhood Asthma Control Test (C-ACT) score. Simultaneously, a control group consisting of 20 children with simple allergic rhinitis, matched for baseline characteristics, was included. SPC measurement was performed in the two groups. The SPC value was significantly higher in the asthma group than that in the control group (165.0 ± 82.8 ng/mL vs 68.4 ± 34.5 ng/mL) (P < 0.001). In the asthma group, SPC was independently associated with FeNO, the ratio of forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC), and forced expiratory flow at 50% and 75% of FVC (FEF50 and FEF75) (all P < 0.05). The severity of nasal symptoms evaluated by the visual analogue scale (N-VAS) was independently associated with FEF75, the maximal mid-expiratory flow (MMEF), and C-ACT score (P < 0.05). Direct pepsin exposure and uncontrolled nasal symptoms may play crucial roles in the pathogenesis and progression of childhood allergic asthma. The SPC value can be considered as a risk factor for asthma in children with allergic rhinitis.

Association between Second-Hand Exposure to E-Cigarettes at Home and Exacerbations in Children with Asthma.

Several studies have shown the effects of e-cigarettes in adults. Nowadays, few data are available in the pediatric population. This study aims to assess the relationship between asthma exacerbations and home exposure to e-cigarettes. We conducted a pilot, retrospective, monocenter, observational study. Demographic and clinical data were collected, including number of asthma exacerbations, need for rescue therapy and/or therapeutic step-up, and Asthma Control Test (ACT) and children-Asthma Control Test (c-ACT) scores. The cohort consisted of 54 patients (5-17 years old), divided into two groups: A, including patients exposed to e-cigarette aerosols; B, including unexposed patients. The statistical analysis showed no relevant variation in the number of asthma symptomatic days and need for rescue therapy in group A versus group B (p = 0.27 and 0.19, respectively). There were no statistically significant variations when also considering the number of patients who needed a therapeutic step-up (p = 0.3). The mean values of ACT and c-ACT were, respectively, 17.2 ± 7.6 and 18.3 ± 5.6 in group A and 19.6 ± 3.8 and 14.6 ± 5.8 in group B (p = 0.3 and 0.4, respectively). Although we did not find a statistically significant correlation between second-hand e-cigarette exposure and asthma exacerbations, our findings suggest that asthmatic children exposed second-hand to e-cigarettes may have increased risk of asthma symptomatic days. Future research is warranted.

Comparison of Telemedicine versus In-Person Visit for Control of Asthma in Children aged 7-17years: A Randomized Controlled Trial.

To compare asthma control between telemedicine and in-person visit in children aged 7 to 17 y. A non-inferiority randomized-controlled trial was conducted at a pediatric chest clinic, involving a total of 192 patients, with 96 children in each group of telemedicine and in-person follow-up. There was a significant improvement in the mean asthma control test (ACT)/ Childhood asthma control test (C-ACT) scores from baseline to three months in both groups, with no significant difference in the change of means between the two groups. The mean difference in ACT/C-ACT score at three months in the telemedicine and in-person visit group was -0.35; 95% CI (-1.30 to +0.10) [p-value 0.09]. There was a significant change in the mean Pediatric Quality of Life index (PQLI) scores from 57.2 ± 10.2 to 66.82 ± 7.99 in the telemedicine group and from 56.1 ± 11.7 to 66.71 ± 4.66 in the in-person visit group, however the mean difference in PQLI score in both the groups was not significant (p = 0.91). There was no significant difference in the number of asthma exacerbations (4 vs. 1) between telemedicine and in-person visit (p = 0.10). The mean telemedicine satisfaction questionnaire score in this study was 3.8 ± 0.7, which indicates that most of the parents were satisfied with the telemedicine follow-up process. This study revealed that telemedicine is non-inferior to in-person visit for follow-up of children with asthma and can be used as an alternative to in-person visit for the management of asthma, especially in remote settings and pandemic situations.

GAMBARAN STATUS KONTROL ASMA DAN KUALITAS HIDUP ANAK DENGAN ASMA DI RSUP PROF. DR. I.G.N.G NGOERAH DENPASAR DAN RSUD WANGAYA DENPASAR TAHUN 2020-2021

Asthma is a chronic and emergency disease in children. Uncontrolled asthma in children can affect the quality of life of children and even lead to death. Bali is the province with the third highest prevalence of asthma after the Special Region of Yogyakarta and East Kalimantan. However, data regarding the description of asthma control status and quality of life of children with asthma in Bali, especially in Denpasar, are still limited. Therefore, the authors want to know the overview of asthma control status and quality of life of children with asthma at Prof. Dr. I.G.N.G Ngoerah Hospital Denpasar and Wangaya Hospital Denpasar in 2020-2021. The design of this research is descriptive observational with a cross-sectional approach. After the approval of the constitutional ethics committee, all children aged 6-11 years with asthma at the Outpatient and Inpatient Respirology Pediatric Clinic Prof. Dr. I.G.N.G Ngoerah Hospital Denpasar and Wangaya Hospital Denpasar in 2020-2021 which is recorded in a complete medical record and has approval for participation in the study by parents/guardians (n=32) will be given a questionnaire containing the child and parent’s biodata, Childhood Asthma Control Test (C-ACT) to assess asthma control status, and Pediatric Quality of Life (PedsQL) to assess children's quality of life through an electronic form. Based on asthma control status, the results showed that 27 children (84.4%) had fully controlled asthma control status and 5 children (15.6%) had partially controlled asthma control status. In controlled asthma control status, all children were male. The majority of children (3 children) have poor nutritional status and some (2 children) have obese nutritional status. All children have a family history of asthma. Most of the children's parents have the latest education in college (3 children), senior high school (1 child), and elementary school (1 child). All parents of children have jobs and most of them (3 parents of children) have salaries above the minimum wage. Based on the quality of life, there were 4 children (12.5%) with a disturbed quality of life and 28 (87.5%) children with an undisturbed quality of life. In terms of quality of life, there were 2 children, male and female, respectively. The majority of these children had good nutritional status (2 children) and did not have a family history of asthma (3 children). The parents of the 2 children have the last education in elementary school, while the other 2 parents have the last education in college. All of the children's parents have jobs and the majority (3 parents of children) have salaries above the minimum wage. Further research is needed with a larger sample size and should be carried out prospectively so that the data obtained is more complete.

Associations between personal apparent temperature exposures and asthma symptoms in children with asthma.

Ambient temperature and relative humidity can affect asthma symptoms. Apparent temperature is a measure of temperature perceived by humans that takes into account the effect of humidity. However, the potential link between personal exposures to apparent temperature and asthma symptoms has not been investigated. We conducted a panel study of 37 asthmatic children, aged 5-11 years, during an early spring season (average daily ambient temperature: 14°C, range: 7-18°C). Asthma symptoms were measured 4 times for each participant with a 2-week interval between consecutive measurements using the Childhood Asthma-Control Test (C-ACT). Average, minimum, and maximum personal apparent temperature exposures, apparent temperature exposure variability (TV), and average ambient temperature were calculated for the 12 hours, 24 hours, week, and 2 weeks prior to each visit. We found that a 10°C lower in 1-week and 2-week average & minimum personal apparent temperature exposures, TV, and average ambient temperature exposures were significantly associated with lower total C-ACT scores by up to 2.2, 1.4, 3.3, and 1.4 points, respectively, indicating worsened asthma symptoms. Our results support that personal apparent temperature exposure is potentially a stronger driver than ambient temperature exposures for the variability in asthma symptom scores. Maintaining a proper personal apparent temperature exposure could be an effective strategy for personalized asthma management.

Psychometric evaluation of an electronic Asthma Symptom Diary for young children

BackgroundPatient-reported outcome measures that facilitate self-report by children are needed to reduce the bias of proxy report. We previously developed an electronic Pediatric Asthma Symptom Diary (ePASD) to assess the severity of daily asthma symptoms and proximal impacts in children aged 6–11 years with mild to severe asthma. The ePASD, administered via a digital application with visuals, sounds, and text, is uniquely designed to minimize the importance of reading skills on children’s ability to self-report accurately. Here, we describe the ePASD’s psychometric properties.MethodsNinety-one children aged 6–11 years with mild to severe asthma and their caregivers participated in 2 study visits, which consisted of training on the provisioned device and completing asthma-specific clinical outcome assessment (COA) questionnaires. The children self-completed the ePASD at home twice daily for 8 consecutive days. The scoring of the ePASD was guided by factor analyses, inter-item correlations, and internal consistencies. Reliability, discriminating ability, construct validity, and responsiveness were evaluated for ePASD items and candidate scores.ResultsAll COAs included in the study—the ePASD, Asthma Control Questionnaire (ACQ), Childhood Asthma Control Test, Pediatric Asthma Quality of Life Questionnaire–Standardized (PAQLQ[S]), and global ratings—demonstrated that the children exhibited few asthma-related symptoms and impacts at all timepoints, and consequently, showed little change over time. Internal consistencies (all Cronbach’s alphas ≥ 0.52) and test-retest reliabilities (all intraclass correlation coefficients ≥ 0.60) were largely satisfactory. Patterns of convergent and divergent correlations supported the construct validity of ePASD scores. The ePASD symptom scores correlated moderately to strongly with PAQLQ(S) Symptom scores (all correlations ≥ − 0.46) and with ACQ scores (all correlations ≥ 0.42), as predicted. Evidence of the discriminating ability of ePASD items and composite scores was demonstrated by known-groups analyses.ConclusionsThe ePASD is a reliable and valid measure of asthma symptoms and proximal impacts in children aged 6–11 years with mild, moderate, or severe asthma. These results lay the psychometric groundwork for use of the ePASD in future clinical trials for the management of pediatric asthma. An ongoing pediatric asthma treatment trial is anticipated to provide evidence of the ePASD’s responsiveness to change.

Childhood Asthma Control Test and spirometry values in school-age children

Objective To determine the relationship between child and parent reports of asthma control using the Childhood Asthma Control Test (C-ACT) and spirometry. Methods This descriptive study included 648 children ages 5–11 years from a school-based asthma program. Not well-controlled asthma was defined as forced expiratory volume in 1 s (FEV1) and by FEV1/forced vital capacity (FVC) of 80% predicted or lower. Sensitivity and specificity of C-ACT scores for low FEV1 and FEV1/FVC levels were calculated. Logistic regression was used to obtain the area under the receiver operating characteristic curve (AUC) for C-ACT score categories by FEV1 level. Results Mean child age was 8.2 years, mean C-ACT score was 20.3 (SD = 3.96), mean FEV1 was 94.3% (SD = 17.1), and mean FEV1/FVC was 81.3 (SD = 8.5). Children with an FEV1 of 80% or less had significantly lower C-ACT scores than those with an FEV1 > 80% (p = .023, t = −2.015, df = 167); 95% CI [. −1.79 to −0.018]). The sensitivity and specificity of a C-ACT score of 19 or less for an FEV1 of 80% predicted or lower were 44.9 and 66.4%. With a C-ACT score of 22 or less, sensitivity and specificity for low FEV1 were 67.7 and 30.9%. The AUC for a C-ACT score of 19 or less and FEV1 of 80% or lower was .444 while the AUC was higher at .507 for a CACT score of 22 or less. Conclusion The C-ACT is a useful screen but spirometry should be performed in children with persistent symptoms to assess current asthma control.

Association between fractional exhaled nitric oxide and therapeutic adherence to controller management in pediatric asthma patients.

Guidelines for asthma management recommend, before establishing additional therapeutic behaviors, to confirm correct use and adequate therapeutic adherence to treatment. Evidence exists on the use of fractional exhaled nitric oxide (FeNO) values for monitoring therapeutic adherence in adults. It is important to establish whether there is a correlation between FeNO and therapeutic adherence in children. This study aims to provide new knowledge about the relationship between FeNO and therapeutic adherence in asthmatic children. Analytical cross-sectional study including asthma patients 5-18 years of age, attending follow-up at Hospital Militar Central (HMC) between May and November 2022 in Colombia. A sociodemographic survey was carried out, followed by the Pediatric Inhaler Adherence Questionnaire (PIAQ), and asthma control test (ACT) or childhood asthma control test (cACT). We defined adequate therapeutic adherence as not missing a single application of inhaled steroids in the last 15 days according to PIAQ. A poisson regression model was carried out including relevant predictors for therapeutic adherence such as FeNO values, age, tobacco exposure at home, atopy, and time since initiation of use of inhaled controller. Eighty-two children with a median age of 10 years (interquartile range: 7-12 years) were included. Adequate therapeutic adherence was reported by 68.3%. After adjusting for age, sex, exposure to cigarette smoke, duration of controller therapy, and atopy, FeNO < 20 ppb was independently associated with adequate therapeutic adherence (RR = 1.5, p = .04, 95% confidence interval: 1.03-2.19). FeNO values seem to be useful to identify pediatric patients with asthma who have adequate adherence to inhaled steroids in a MIC.

Parenting style and child asthma control in families of school-age children with asthma: The mediating effects of children's general self-efficacy and medication adherence

PurposeParenting style plays a pivotal role in children's chronic disease control. However, the relationship and underlying mechanism between parenting style and asthma control remain unclear. This study investigated the effects of parenting style on children's general self-efficacy, medication adherence and asthma control and the mediating effects of general self-efficacy and medication adherence among school-age children with asthma. Design and methodsA cross-sectional study with a convenience sampling approach was conducted. This study followed the STROBE guidelines. School-age children with asthma and their parents (N = 211) from pediatric respiratory clinics in China completed the General Questionnaire, Short-Egna Minnen av. Barndoms Uppfostran-Chinese, General Self-Efficacy Scale, Medication Adherence Questionnaire and Childhood Asthma Control Test. Structural equation modeling was used to examine the mediation models. ResultsPositive parenting style was positively correlated with child general self-efficacy, medication adherence and asthma control (r = 0.602, 0.572, 0.613, p < 0.001). Negative parenting style was negatively correlated with child general self-efficacy, medication adherence and asthma control (r = −0.535, −0.598, −0.586, p < 0.001). Structure Equation Modle (SEM) results indicated that the relationships between positive parenting style, negative parenting style and child asthma control were mediated by general self-efficacy (Effect Size [ES]: 0.209, 95%CI [0.075, 0.372]; and ES: -0.229, 95%CI [−0.387, −0.103], respectively) and medication adherence (ES: 0.128, 95%CI [0.032, 0.322]; and ES: -0.190, 95%CI [−0.432, −0.071], respectively) and together in serial (ES: 0.177, 95%CI [0.076, 0.295]; and ES: -0.118, 95%CI [−0.235, −0.020], respectively). ConclusionsParenting style may impact child asthma through both child general self-efficacy and medication adherence. The study may provide useful intervention targets for improving asthma control. Practice implicationsNurses should encourage parents to increase positive parenting style while decreasing negative parenting style. Family interventions focusing on general self-efficacy and medication adherence may be advantageous to improve asthma control.
