Objectives: In children with asthma exacerbations, we evaluated the relationship between Canadian Acute Respiratory Illness and Flu Scale (CARIFS) scores and (a) Asthma Diary Scale (ADS) scores for 14 days; (b) Pediatric Asthma Caregiver's Quality of Life (QoL) Questionnaire (PACQLQ) scores on days 1, 7 and 14; (c) viral detection. We hypothesized that in children with acute asthma, CARIFS scores correlate with ADS and PACQLQ scores over time and that viruses have little impact on CARIFS scores., Methods: In children aged 2-16 years who presented with acute asthma to the Emergency Departments of 2 hospitals, we documented the clinical history, examination, asthma severity at baseline and on presentation. Eighteen respiratory pathogens were determined by PCR on nasopharyngeal aspirate (NPA) collected on recruitment. The parent(s) recorded their child's daily CARIFS and ADS and weekly PACQLQ for 14 days. We used Spearman's correlation to relate the scores of 108 children., Results: CARIFS scores correlated well with ADS scores throughout 14 days (r s ranged 0.30-0.67). CARIFS and PACQLQ scores correlated -0.28, -0.14 and -0.44 on days 1, 7 and 14 respectively. There was no significant difference in CARIFS scores between children whose NPAs were PCR virus-positive or -negative over 14 days., Conclusions: CARIFS and ADS scores correlated well as a disease severity measure during the recovery period in children with acute asthma and this was not influenced by the virus state. The ADS may be used as an alternative in selected situations. The CARIFS reflects different aspects to acute asthma severity and QoL.

There is increasing awareness of bronchiectasis in children and adolescents, a chronic pulmonary disorder associated with poor quality of life for the child/adolescent and their parents, recurrent exacerbations, and costs to the family and health systems. Optimal treatment improves clinical outcomes. Several national guidelines exist, but there are no international guidelines.The European Respiratory Society (ERS) Task Force for the management of paediatric bronchiectasis sought to identify evidence-based management (investigation and treatment) strategies. It used the ERS standardised methodology that included a systematic review of the literature and application of the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to define the quality of the evidence and level of recommendations.A multidisciplinary team of specialists in paediatric and adult respiratory medicine, infectious disease, physiotherapy, primary care, nursing, radiology, immunology, methodology, patient advocacy and parents of children/adolescents with bronchiectasis considered the most relevant clinical questions (for both clinicians and patients) related to managing paediatric bronchiectasis. 14 key clinical questions (seven PICO (Patient, Intervention, Comparison, Outcome) and seven narrative) were generated. The outcomes for each PICO were decided by voting by the panel and parent/patient advisory group.This guideline addresses the definition, diagnostic approach and antibiotic treatment of exacerbations, pathogen eradication, long-term antibiotic therapy, asthma-type therapies (inhaled corticosteroids and bronchodilators), mucoactive drugs, airway clearance, investigation of underlying causes of bronchiectasis, disease monitoring, factors to consider before surgical treatment, and the reversibility and prevention of bronchiectasis in children/adolescents. Benchmarking quality of care for children/adolescents with bronchiectasis to improve clinical outcomes and evidence gaps for future research could be based on these recommendations., Competing Interests: Conflict of interest: A.B.

Objectives: In hospitalized and nonhospitalized children with asthma exacerbations, we evaluated the determinants of (a) prolonged cough on day-14 and (b) asthma quality of life (QoL) questionnaires for parents (PACQLQ) on day-21. We hypothesized that children with more severe acute asthma are more likely to have prolonged cough and/or poorer PACQLQ during the recovery phase., Design: Prospective cohort study performed during 2009-2011., Methodology: Two hundred and forty-four children aged 2-16 years presenting with acute asthma to the Emergency Departments of two hospitals were recruited. Clinical history, examination, baseline asthma severity, and acute asthma severity on presentation were documented. Validated daily cough diaries and weekly PACQLQ were recorded for 14 and 21 days, respectively., Results: 34.4% and 32.2% of children who returned the daytime and nighttime cough diaries respectively had a prolonged cough. Those on regular inhaled corticosteroids (ICS) were significantly more likely to have a daytime or nighttime cough score of ≥1 on day-14 (odds ratio [OR adjusted ] = 4.70, 95% confidence interval [CI] 1.65, 13.35, p = .004 and OR adjusted  = 2.65, 95% CI 1.05, 6.69, p = .040, respectively). PACQLQ on day-21 was significantly poorer in younger children (mean difference [MD] = -0.04 per year, 95% CI -0.08, -0.01, p = .016), those on ICS (MD = -0.31, 95% CI -0.52, -0.09, p = .005), leukotriene antagonists (MD = -0.42, 95% CI -0.83, -0.02, p = .040) and in those who had an unplanned visit for asthma on day-21 (MD = -1.20, 95% CI -1.61, -0.78, p = .0001)., Conclusions: Post an acute asthma exacerbation, children on regular ICS were more likely to have prolonged cough and poorer QoL. While this may be reflective of asthma severity or control, its association deserves further evaluation., (© 2020 Wiley Periodicals LLC.)

Background: Acute respiratory illnesses cause substantial morbidity worldwide. Cough is a common symptom in these childhood respiratory illnesses, but no large cohort data are available on whether various cough characteristics can differentiate between these etiologies., Research Question: Can various clinically based cough characteristics (frequency [daytime/ nighttime], the sound itself, or type [wet/dry]) be used to differentiate common etiologies (asthma, bronchiolitis, pneumonia, other acute respiratory infections) of acute cough in children?, Study Design and Methods: Between 2017 and 2019, children aged 2 weeks to ≤16 years, hospitalized with asthma, bronchiolitis, pneumonia, other acute respiratory infections, or control subjects were enrolled. Spontaneous coughs were digitally recorded over 24 hours except for the control subjects, who provided three voluntary coughs. Coughs were extracted and frequency defined (coughs/hour). Cough sounds and type were assessed independently by two observers blinded to the clinical data. Cough scored by a respiratory specialist was compared with discharge diagnosis using agreement (Cohen's kappa coefficient [қ]), sensitivity, and specificity. Caregiver-reported cough scores were related with objective cough frequency using Spearman coefficient (r s )., Results: A cohort of 148 children (n = 118 with respiratory illnesses, n = 30 control subjects), median age = 2.0 years (interquartile range, 0.7-3.9), 58% males, and 50% First Nations children were enrolled. In those with respiratory illnesses, caregiver-reported cough scores and wet cough (range, 42%-63%) was similar. Overall agreement in diagnosis between the respiratory specialist and discharge diagnosis was slight (қ = 0.13; 95% CI, 0.03 to 0.22). Among diagnoses, specificity (8%-74%) and sensitivity (53%-100%) varied. Interrater agreement in cough type (wet/dry) between blinded observers was almost perfect (қ = 0.89; 95% CI, 0.81 to 0.97). Objective cough frequency was significantly correlated with reported cough scores using visual analog scale (r s  = 0.43; bias-corrected 95% CI, 0.25 to 0.56) and verbal categorical description daytime score (r s  = 0.39; bias-corrected 95% CI, 0.22 to 0.54)., Interpretation: Cough characteristics alone are not distinct enough to accurately differentiate between common acute respiratory illnesses in children., (Copyright © 2020 American College of Chest Physicians.

Background: People with asthma who come from minority groups often have poorer asthma outcomes, including more acute asthma-related doctor visits for flare-ups. Various programmes used to educate and empower people with asthma have previously been shown to improve certain asthma outcomes (e.g. adherence outcomes, asthma knowledge scores in children and parents, and cost-effectiveness). Models of care for chronic diseases in minority groups usually include a focus of the cultural context of the individual, and not just the symptoms of the disease. Therefore, questions about whether tailoring asthma education programmes that are culturally specific for people from minority groups are effective at improving asthma-related outcomes, that are feasible and cost-effective need to be answered., Objectives: To determine whether culture-specific asthma education programmes, in comparison to generic asthma education programmes or usual care, improve asthma-related outcomes in children and adults with asthma who belong to minority groups., Search Methods: We searched the Cochrane Register of Controlled Trials (CENTRAL), the Cochrane Airways Group Specialised Register, MEDLINE, Embase, review articles and reference lists of relevant articles. The latest search fully incorporated into the review was performed in June 2016., Selection Criteria: Randomised controlled trials (RCTs) comparing the use of culture-specific asthma education programmes with generic asthma education programmes, or usual care, in adults or children from minority groups with asthma., Data Collection and Analysis: Two review authors independently selected, extracted and assessed the data for inclusion. We contacted study authors for further information if required., Main Results: In this review update, an additional three studies and 220 participants were added. A total of seven RCTs (two in adults, four in children, one in both children and adults) with 837 participants (aged from one to 63 years) with asthma from ethnic minority groups were eligible for inclusion in this review. The methodological quality of studies ranged from very low to low. For our primary outcome (asthma exacerbations during follow-up), the quality of evidence was low for all outcomes. In adults, use of a culture-specific programme, compared to generic programmes or usual care did not significantly reduce the number of participants from two studies with 294 participants for: exacerbations with one or more exacerbations during follow-up (odds ratio (OR) 0.80, 95% confidence interval (CI) 0.50 to 1.26), hospitalisations over 12 months (OR 0.83, 95% CI 0.31 to 2.22) and exacerbations requiring oral corticosteroids (OR 0.97, 95% CI 0.55 to 1.73). However, use of a culture-specific programme, improved asthma quality of life scores in 280 adults from two studies (mean difference (MD) 0.26, 95% CI 0.17 to 0.36) (although the MD was less then the minimal important difference for the score). In children, use of a culture-specific programme was superior to generic programmes or usual care in reducing severe asthma exacerbations requiring hospitalisation in two studies with 305 children (rate ratio 0.48, 95% CI 0.24 to 0.95), asthma control in one study with 62 children and QoL in three studies with 213 children, but not for the number of exacerbations during follow-up (OR 1.55, 95% CI 0.66 to 3.66) or the number of exacerbations (MD 0.18, 95% CI -0.25 to 0.62) among 100 children from two studies., Authors' Conclusions: The available evidence showed that culture-specific education programmes for adults and children from minority groups are likely effective in improving asthma-related outcomes. This review was limited by few studies and evidence of very low to low quality. Not all asthma-related outcomes improved with culture-specific programs for both adults and children. Nevertheless, while modified culture-specific education programs are usually more time intensive, the findings of this review suggest using culture-specific asthma education programmes for children and adults from minority groups. However, more robust RCTs are needed to further strengthen the quality of evidence and determine the cost-effectiveness of culture-specific programs.

Aim: Indigenous Australians with asthma have higher morbidity and mortality compared with non-Indigenous Australians. In children hospitalised with acute asthma, we aimed to (i) determine if acute severity, risk factors and management differed between Indigenous and non-Indigenous children; and (ii) identify intervention points to reduce morbidity and mortality of asthma., Methods: Retrospective review of 200 children hospitalised to Royal Darwin Hospital with asthma. We compared admission characteristics, severity indices, treatment, discharge plans and readmissions in Indigenous and non-Indigenous children., Results: Median age was 3.6 years (interquartile range 2.2, 6.8). A significantly higher proportion of Indigenous children (95.2%) were exposed to tobacco smoke compared with non-Indigenous children (45.7%). The difference in proportions was -0.41 (95% confidence interval (CI) -0.60, -0.22). Other risk factors, asthma severity (moderate 83.9% vs. 83.3%; severe 16% vs. 16.1%), length of stay (1.9 vs. 1.3 days) and readmission rate (27.4% vs. 27.5%) were similar between Indigenous and non-Indigenous children. Indigenous children were significantly more likely to be followed up in a community clinic (difference in proportions = 0.10, 95% CI 0.1, 0.17) and less likely by a paediatrician. Only 62.5% of all children had an asthma action plan on discharge., Conclusion: Unlike other common respiratory diseases requiring hospitalisation, biological factors are unlikely major contributors to the known gap in asthma outcomes between Indigenous and non-Indigenous children. Intervention points include better identification, documentation and management of tobacco smoke exposure, delivery of salbutamol and discharge planning (including education and utilisation of asthma action plans)., (© 2013 The Authors.
