CONTEXT: Invasive pneumococcal disease (IPD) and pneumonia are a leading cause of morbidity and mortality throughout the world, and asthma is the most common chronic disease of childhood. OBJECTIVE: To evaluate the risk of IPD or pneumonia among children with asthma after the introduction of pneumococcal conjugate vaccines (PCVs). DATA SOURCES: Four electronic databases were searched. STUDY SELECTION: We selected all cohorts or case-control studies of IPD and pneumonia in populations who already received PCV (largely 7-valent pneumococcal conjugate vaccine), but not 23-valent pneumococcal polysaccharide, in which authors reported data for children with asthma and in which healthy controls were included, without language restriction. DATA EXTRACTION: Two reviewers independently reviewed all studies. Primary outcomes were occurrence of IPD and pneumonia. Secondary outcomes included mortality, hospital admissions, hospital length of stay, ICU admission, respiratory support, costs, and additional medication use. RESULTS: Five studies met inclusion criteria; of those, 3 retrospective cohorts (~26 million person-years) and 1 case-control study (N = 3294 children) qualified for the meta-analysis. Children with asthma had 90% higher odds of IPD than healthy controls (odds ratio = 1.90; 95% confidence interval = 1.63-2.11; I² = 1.7%). Pneumonia was also more frequent among children with asthma than among controls, and 1 study reported that pneumonia-associated costs increased by asthma severity. LIMITATIONS: None of the identified studies had information of asthma therapy or compliance. CONCLUSIONS: Despite PCV vaccination, children with asthma continue to have a higher risk of IPD than children without asthma. Further research is needed to assess the need for supplemental 23-valent pneumococcal polysaccharide vaccination in children with asthma, regardless of their use of oral steroids.

Down syndrome (DS) is the most common chromosomal condition in live-born infants worldwide, and lower respiratory infection caused by respiratory syncytial virus (RSV) is a leading cause of hospital admissions. OBJECTIVE: To evaluate RSV-associated morbidity among children with DS compared with a population without DS. DATA SOURCES: Four electronic databases were searched. STUDY SELECTION: All cohorts or case-control studies of DS with an assessment of RSV infection and the associated morbidity or mortality were included without language restriction. DATA EXTRACTION: Two reviewers independently reviewed all studies. The primary outcomes were hospital admission and mortality. Secondary outcomes included length of hospital stay, oxygen requirement, ICU admission, need for respiratory support, and additional medication use. RESULTS: Twelve studies (n = 1 149 171) from 10 different countries met the inclusion criteria; 10 studies were cohort studies, 1 study was retrospective, and 1 study had both designs. DS was associated with a higher risk of hospitalization (odds ratio [OR]: 8.69; 95% confidence interval [CI]: 7.33-10.30; I² = 11%) and mortality (OR: 9.4; 95% CI: 2.26-39.15; I² = 38%) compared with what was seen in controls. Children with DS had an increased length of hospital stay (mean difference: 4.73 days; 95% CI: 2.12-7.33; I² = 0%), oxygen requirement (OR: 6.53; 95% CI: 2.22-19.19; I² = 0%), ICU admission (OR: 2.56; 95% CI: 1.17-5.59; I² = 0%), need for mechanical ventilation (OR: 2.56; 95% CI: 1.17-5.59; I² = 0%), and additional medication use (OR: 2.65 [95% CI: 1.38-5.08; I² = 0%] for systemic corticosteroids and OR: 5.82 [95% CI: 2.66-12.69; I² = 0%] for antibiotics) than controls. LIMITATIONS: DS subgroups with and without other additional risk factors were not reported in all of the included studies. CONCLUSIONS: Children with DS had a significantly higher risk of severe RSV infection than children without DS. [ABSTRACT FROM AUTHOR]

Asthma is a widespread disease affecting approximately 300-million people globally. This condition leads to significant morbidity, mortality, and economic strain worldwide. Recent clinical and laboratory research advancements have illuminated the immunological factors contributing to asthma. As of now, asthma is understood to be a heterogeneous disease. Personalized medicine involves categorizing asthma by its endotypes, linking observable characteristics to specific immunological mechanisms. Identifying these endotypic mechanisms is paramount in accurately profiling patients and tailoring therapeutic approaches using innovative biological agents targeting distinct immune pathways. This article presents a synopsis of the key immunological mechanisms implicated in the pathogenesis and manifestation of the disease's phenotypic traits and individualized treatments for severe asthma subtypes.

The clinical manifestations of asthma in children are highly variable, are associated with different molecular and cellular mechanisms, and are characterized by common symptoms that may diversify in frequency and intensity throughout life. It is a disease that generally begins in the first five years of life, and it is essential to promptly identify patients at high risk of developing asthma by using different prediction models. The aim of this review regarding the early prediction of asthma is to summarize predictive factors for the course of asthma, including lung function, allergic comorbidity, and relevant data from the patient's medical history, among other factors. This review also highlights the epigenetic factors that are involved, such as DNA methylation and asthma risk, microRNA expression, and histone modification. The different tools that have been developed in recent years for use in asthma prediction, including machine learning approaches, are presented and compared. In this review, emphasis is placed on molecular mechanisms and biomarkers that can be used as predictors of asthma in children. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study is to summarize the principal findings in the literature about acute asthma management in children.Methods: Systematic reviews of randomized clinical trials (SRCTs) with or without meta-analysis in children (1–18 years) admitted to the emergency department (ED) were retrieved using five data bases. Methodological quality was determined using the AMSTAR tool.Results: One hundred and three studies were retrieved. Among those, 28 SRCTs were included: seven SRCTs related to short-acting beta2-agonists (SABA), three to ipratropium bromide (IB), eight to corticosteroids, one to racemic adrenaline, one to leukotriene receptor antagonists (LTRA), four to magnesium sulfate, one to intravenous (IV) SABA, one to IV aminophylline, one to IV ketamine, and one to antibiotics. It was determined that administering SABA by MDI-VHC is superior to using a nebulizer, because it decreases the hospital admission rate, improves the clinical score, results in a shorter time in the ED, and causes fewer adverse effects. Levalbuterol and albuterol were similar. In patients with moderate to severe exacerbations, IB+SABA was superior to SABA, decreasing hospital admission and improving the clinical score. SABA heliox administered by nebulizer decreased exacerbation severity compared to oxygen. Inhaled corticosteroids (ICS), especially administered by nebulizer, showed results similar to oral corticosteroids (OCS) with respect to reducing hospital admission, unscheduled visits, and the requirement of additional systemic corticosteroids. ICS or OCS following ED discharge was similar with regard to relapse. Compared with a placebo, IV magnesium reduced hospital admission and improved lung function.Conclusions: SRCTs are useful for guiding decisions in acute asthma treatment. [ABSTRACT FROM PUBLISHER]

Objective: To summarize the principal findings pertaining to most effective long-term pharmacologic treatment of childhood asthma. Methods: Systematic reviews of randomized clinical trials (SRCTs) on pharmacologic chronic treatment in children (1-18 years) with persistent asthma were retrieved through MEDLINE, EMBASE, CINAHL, SCOPUS, and CDSR (up to January2014). Results: One hundred eighty-three SRCTs were searched from databases. Among those, 39 SRCTs were included: two were related to step 1, 24 to step 2, nine to steps 3 and 4, and four to step 5 (according with NAEPP and GINA guidelines). The methodological quality of these SRCTs was determined by using the AMSTAR tool. Results: For step 1: addition of ipatropium bromide to short-acting beta2-agonists does not show any benefit. For step 2: in preschoolers, inhaled corticosteroids (ICSs) reduce severe exacerbations and improve other clinical and lung function parameters. In children, ICSs are superior to leukotriene receptor antagonist (LTRA), cromones, or xantines in reducing severe exacerbations, improving lung function and other clinical outcomes. Fluticasone propionate (FP) is better than beclomethasone dipropionate (BDP) or budesonide only for lung function; but similar to hydrofluoroalkane- BDP or to ciclosenide. Compared to low ICSs doses, moderate doses result in only better lung function, but this is not true for FP. For steps 3 and 4: adding LTRA to ICS confers a small benefit; adding LABA improves lung function but does not reduce exacerbations more than double or higher ICS doses. For step 5: adding omalizumab decreases exacerbations. Conclusions: SRCTs are useful for guiding decisions in chronic childhood asthma treatment. [ABSTRACT FROM AUTHOR]

Postinfectious bronchiolitis obliterans ( PIBO) is an infrequent chronic lung that causes irreversible obstruction and, or, obliteration of the smaller airways. This review particularly focuses on more than 30 studies from South America. Conclusion The initial PIBO event occurs in the early years of life and is strongly associated with adenovirus infection and the need for mechanical ventilator support. Treatment requires a multidisciplinary strategy. Multicentre studies are needed to determine progression, optimal management and long-term follow-up. [ABSTRACT FROM AUTHOR]

Aim To evaluate the effectiveness of chest physiotherapy ( CPT), which provides slow and long expiratory flow and assisted cough techniques, in infants receiving outpatient care for acute wheezing episodes. Methods Forty-eight infants with moderate acute wheezing episodes were randomised to receive either salbutamol MDI with CPT (n = 25) or without CPT (n = 23). The clinical score and SpO2 levels were recorded, before and after treatment, in a blinded design. The primary outcome was discharge after the first hour of treatment: clinical score ≤5/12 and SpO2 ≥ 93%. Secondary outcomes were the number of admissions to hospital after the second hour, use of oral corticosteroid bursts and admissions to hospital on day seven. Results There were no differences between children with and without CPT in discharge rate (92% vs. 87%), clinical score (median [ IQR]: 2.8 [2.2-3.3] vs. 3.4 [2.8-4.1]) and SpO2= (96.4 [95.7-97.1] vs. 96.0 [94.9-96.5]) after the first hour of treatment or in the number of hospital admissions after the second hour. No differences were observed at days seven and 28 following treatment. Conclusion There was no evidence of clinical benefits from these specific CPT techniques for infants receiving outpatient care for acute wheezing episodes. [ABSTRACT FROM AUTHOR]

Objective. The aim of this post hoc analysis was to establish the relationship between FENO levels and the asthma predictive index (API) among infants with recurrent wheezing. Methods. Infants with recurrent wheezing (three or more episodes) were recruited consecutively and online FENO tests at tidal breathing with multiple breaths were performed. Results. Twenty-seven (84%) out of 32 infants (median age of 12 months) who met the inclusion criteria for this post hoc analysis, successfully performed the FENO determinations. Eighteen (66%) infants were classified with positive stringent API. FENO levels were significantly higher among patients with positive API than those with negative (median [IQR] of 12.3 [14.8] ppb vs. 4.1 [7.9] ppb, respectively, p = .016). Furthermore, FENO and positive API had a significant correlation (Spearman's rho, ρ = 0.4741, p = .0125). After logistic regression analysis including FENO levels, gender, age, and use of controller therapy, FENO was the only variable that was marginally related to API (OR = 1.12, 95% CI: 0.99-1.27, p = .07). Conclusion. Infants with recurrent wheezing who had a positive stringent API already had higher FENO levels than those with a negative API. This finding needs to be corroborated in a larger prospective study. [ABSTRACT FROM AUTHOR]

Background. Atopy and bronchial hyperreactivity are factors related to severe and unremitting asthma of childhood; however, the prevalence of these factors could be different according to age of the child. Objective. To determine if methacholine bronchial hyperreactivity (BHR) differs between atopic and nonatopic preschoolers and schoolchildren with mild-moderate asthma. Methods. Data obtained from 340 children with diagnosis of asthma or recurrent wheezing, matched by atopic conditions (positive or negative skin prick test) and age, and who underwent a methacholine bronchial challenge test (by spirometry in schoolchildren and by transcutaneous oxygen pressure [TcPo2] in preschoolers) were reviewed. Results. Among 136 schoolchildren (9.07 ± 2.5 years), the prevalence of positive BHR was significantly higher among atopics than nonatopics (75% versus 48.5%, p = .001, respectively), even after controlling for gender and nutritional status (adjusted odds ratio [aOR] = 3.2129, 95% confidence interval [CI]: 1.5-6.8; p = .002). In addition, atopic schoolchildren had lower PC20 and required a lower threshold dose of methacholine to induce a reaction (0.53 versus 0.82 mg/ml, p = .055 and .5 versus 1 mg/ml, p = .02, respectively) than nonatopics. Nevertheless, basal and predicted forced expiratory volume in one second (FEV1) were similar between groups. In contrast, among 204 preschoolers (4.74 ± 1.1 years), there were no differences in the prevalence of positive BHR between atopics and nonatopics (74.5% versus 72.5%, p = .75, respectively). Furthermore, basal TcPo2, a higher fall of TcPo2 and lower threshold doses of methacholine required for induction as measured by TcPo2 were similar between the atopic and nonatopic preschoolers. Conclusions. Atopic asthmatic schoolchildren have greater hyperresponsiveness to methacholine than nonatopics (only among those with normal nutritional status). However, atopic and nonatopic asthmatic preschoolers have similar hyperresponsiveness to methacholine. Therefore, factors different from atopy may be responsible for wheeze in younger children.

The relationship between asthma and obesity has been documented in children and adolescents; however, few studies on metabolic syndrome and asthma have been performed. Objective. To determine the prevalence of metabolic syndrome in adolescents among the following groups: obese with asthma (OA), obese without asthma (ONA), nonobese with asthma (NOA), and nonobese without asthma (NONA). Patients and Methods. The authors measured anthropometric (height, weight, waist circumference, body mass index, and waist-hip ratio), clinical (Tanner stage, blood pressure, fat and muscle reserve, and exercise), and biochemical parameters (basal and load glucose, cholesterol, triglycerides, high-density lipoproteins, uric acid, and insulin) in 500 Mexican adolescents. Results. A total of 111 OA, 198 ONA, 63 NOA, and 71 NONA adolescents completed the study. There were no differences in age, height, Tanner stage, high-density lipoproteins, or basal glucose among groups. Cholesterol, triglycerides, uric acid, basal insulin, and homeostasis model assessment (HOMA)-IR were significantly higher among the obese than nonobese groups but were similar between the OA and ONA groups. The prevalence of impaired fasting glucose was significantly higher among ONA versus OA males. The prevalence of metabolic syndrome (define as ≥3 abnormal cardiometabolic risk factors by de Ferranti, Cook, and International Diabetes Federation [IDF] criteria) was higher among OA teens than in the ONA group; however, this association was significant only among males. Adolescents from the ONA group were able to perform significantly more vigorous exercise than the other groups. Conclusion. Adolescent males who were obese and also had mild persistent asthma had a significantly higher prevalence of metabolic syndrome than obese males without asthma. However, overall, asthma seems to confer a protective effect against the prediabetes condition in males. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To compare the efficacy of inhaled corticosteroids (ICS) versus montelukast (MONT) in schoolchildren and adolescents with mild–moderate persistent asthma. METHODS: Randomised, prospective, controlled trials published January 1996 to November 2009 with a minimum of 4 weeks of ICS versus MONT and of ICS versus MONT+ICS were retrieved through Medline, Embase and Central databases. The primary outcome was asthma exacerbations requiring systemic corticosteroids (AEX); secondary outcomes were pulmonary function, withdrawal/hospitalisation due to AEX, change in symptoms score, rescue-medication-free days, albuterol use, adverse effects and adherence. RESULTS: Of 124 studies identified, 18 studies (n=3757 patients) met criteria for inclusion (13 compared ICS vs MONT, 3 ICS vs MONT+ICS and 2 ICS vs MONT vs ICS+MONT). Patients receiving ICS showed a significantly lower risk for AEX than those with MONT (RR=0.83, 95% CI 0.72 to 0.96, p=0.01); post-hoc analysis suggests this effect was independent of quality, sponsorship and study duration. Children treated with ICS had a significant higher pulmonary function (final FEV1% predicted, change from baseline FEV1%, final morning peak expiratory flow (PEF)) and better clinical parameters (albuterol use, symptom score, rescue-medication-free days, withdrawals due to AEX) versus MONT. No significant difference in primary or secondary outcomes was found when MONT was added on to ICS versus ICS alone; however, these analyses were based on only two studies. CONCLUSIONS: Schoolchildren and adolescents with mild-moderate persistent asthma treated with ICS had less AEX and better lung function and asthma control than with MONT. There are insufficient data to determine whether the addition of MONT to ICS improves outcome. [ABSTRACT FROM AUTHOR]

Monitoring is a major component of asthma management in children. Regular monitoring allows for diagnosis confirmation, treatment optimization, and natural history review. Numerous factors that may affect disease activity and patient well‐being need to be monitored: response and adherence to treatment, disease control, disease progression, comorbidities, quality of life, medication side‐effects, allergen and irritant exposures, diet and more. However, the prioritization of such factors and the selection of relevant assessment tools is an unmet need. Furthermore, rapidly developing technologies promise new opportunities for closer, or even "real‐time," monitoring between visits. Following an approach that included needs assessment, evidence appraisal, and Delphi consensus, the PeARL Think Tank, in collaboration with major international professional and patient organizations, has developed a set of 24 recommendations on pediatric asthma monitoring, to support healthcare professionals in decision‐making and care pathway design.

In recent years, some new concepts have been added to asthma treatment such as "anti-inflammatory reliever" (β2-agonist use associated to an inhaled corticosteroid (ICS) as a reliever treatment) that combines the benefits of both therapies and provides short- and long-term benefits for treatment in asthma patients. Robust evidence has been presented in patients over 12 years, and the main changes in the international guidelines for asthma treatment were originally made in this age group. However, a few suggestions have been added to treatments in younger patients, in part because of the scarce evidence that exists in this group. We aim to analyze the information regarding the utilization of ICS + fast-acting beta-agonist (FABA) combination in children between 6 and 11 years. Although up until today only three published trials exist (two studies use beclomethasone + albuterol and one study uses budesonide + formoterol), they provide significant information on the benefits of ICS + FABA use in this population.

Objective: Although the efficacy of systemic corticosteroids (SCs) in acute asthma exacerbations is well established, the fact that many children still require admission to hospital and that SCs have a slow onset of action are cause of concern. For this reason, the use of inhaled corticosteroids (ICS) as a therapy added to SCs has been explored, with no clarity about its cost-effectiveness. The aim of the present study was to evaluate the cost-effectiveness of ICS in addition to SCs (ICS + SCs) compared to standard therapy with SCs for treating pediatric asthma exacerbations. Methods: A decision-analysis model was developed to estimate the cost-effectiveness of SCs compared to ICS + SCs for treating pediatric patients with acute asthma exacerbations. Effectiveness parameters were obtained from a systematic review of the literature. Cost data obtained from hospital bills and from the national manual of drug prices. The study was carried out from the perspective of the national healthcare system in Colombia. The main outcome of the model was avoidance of hospital admission. Results: For the base-case analysis, the model showed that compared to SCs, therapy with ICS + SCs was associated with lower total costs (US$88.76 vs.US$97.71 average cost per patient) and a lower probability of hospital admission (0.9060 vs. 0.9000), thus showing dominance. Conclusions: This study shows that compared with standard therapy with SCs, ICS + SCs for treating pediatric patients with acute asthma exacerbations is the preferred strategy because it was associated with a lower probability of hospital admission, at lower total treatment costs.

Introduction: The role of macrolides for treatment of children with acute asthma or wheezing exacerbations is unclear. Objective: The aim of this systematic review was to evaluate the effectiveness of macrolides in children with recurrent wheezing presenting with acute asthma or wheezing exacerbation. Methods: We conducted an electronic search in MEDLINE, EMBASE, CINAHL, LILACS, CENTRAL, and ClinicalTrials.gov. Study selection criteria: Randomized controlled trials of macrolides (any macrolide) compared with placebo or standard treatment in children up to 18 years with recurrent wheezing/asthma presenting with an acute exacerbation. Outcomes: Primary outcomes were need for hospitalization and/or time of acute asthma/wheezing symptoms resolution; secondary outcomes were duration of stay in the emergency department (ED)/clinic, severity of symptoms of the index episode, use of additional systemic corticosteroids or short active β-2 agonists, changes in lung function measures, ED visit/hospitalization during first week after index episode, time to next exacerbation, or adverse effects (AEs). Results: Only three studies met the inclusion criteria (n = 334 children, 410 treated episodes); two studies included recurrent wheezers and the third included asthmatic children. There was no difference in hospitalization between groups, but children treated with macrolides had a significantly lower time to symptoms resolution than controls, although the magnitude of benefit remains to be quantified due to no normal distribution data presented. There was no difference in time to next episode of exacerbation (HR 0.96; 95% CI 0.71–1.28; I2 = 0%; p = 0.77). In one study, children receiving macrolides had a significant decrease in the severity of symptoms, decrease use of salbutamol, and another study showed improved lung function. No study evaluated antibiotic resistance development. Conclusions: Limited evidence support that a macrolide trial could be considered in children with acute asthma or recurrent wheezing exacerbation. [ABSTRACT FROM AUTHOR]

Rationale, aims, and objectives: The aim of the present study was to determine the cost‐effectiveness of the utilization of "good practice" according to a bronchiolitis clinical practice guideline (CPG) in a population of infants hospitalized for acute bronchiolitis. Method: A decision‐analysis model was developed in order to estimate the cost‐effectiveness of the utilization of "good practice" compared with the lack of use of "good practice" according to a bronchiolitis evidence‐based CPG. The effectiveness parameters and costs of the model were obtained from electronic medical records. The main outcome was the readmission of the patients within 10 days of post discharge. Results: Compared with lack of "good practice," the utilization of "good practice" in the diagnosis and management of patients with bronchiolitis was associated with both fewer patients readmitted within 10 days of post discharge (0.88 vs 0.99 on average per patient) and lower costs (US$1529.3 versus $1709.1 average cost per patient), thus leading to dominance. Results were robust to deterministic and probabilistic sensitivity analyses. Conclusions: Compared with lack of "good practice," the utilization of "good practice" in the diagnosis and management of acute bronchiolitis according to a bronchiolitis CPG is a dominant strategy because it involves both fewer patients readmitted within 10 days of post discharge and lower costs.

Objective: The objective of this article was to summarize the findings of all the available studies on alternative pharmacological treatments for asthma and assess their methodological quality, as well as to identify the main drivers of the cost effectiveness of pharmacological treatments for the disease.Methods: A systematic review of the literature in seven electronic databases was conducted in order to identify all the available health economic evidence on alternative pharmacological treatments for asthma published up to April 2017. The reporting quality of the included studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement.Results: A total of 72 studies were included in the review, classified as follows: medications for acute asthma treatment (n = 5, 6.9%); inhaled corticosteroids (ICS) administered alone or in conjunction with long-acting β-agonists (LABA) or tiotropium for chronic asthma treatment (n = 38, 52.8%); direct comparisons between different combinations of ICS, ICS/LABA, leukotriene receptor antagonists (LTRA), and sodium cromoglycate for chronic asthma treatment (n = 14, 19.4%); and omalizumab for chronic asthma treatment (n = 15, 20.8%). ICS were reported to be cost effective when compared with LTRA for the management of persistent asthma. In patients with inadequately controlled asthma taking ICS, the addition of long-acting β-agonist (LABA) preparations has been demonstrated to be cost effective, especially when combinations of ICS/LABA containing formoterol are used for both maintenance and reliever therapy. In patients with uncontrolled severe persistent allergic asthma, omalizumab therapy could be cost effective in a carefully selected subgroup of patients with the more severe forms of the disease. The quality of reporting in the studies, according to the CHEERS checklist, was very uneven. The main cost-effectiveness drivers identified were the cost or rate of asthma exacerbations, the cost or rate of the use of asthma medications, the asthma mortality risk, and the rate of utilization of health services for asthma.Conclusions: The present findings are in line with the pharmacological recommendations for stepwise management of asthma given in the most recent evidence-based clinical practice guidelines for the disease. The identified reporting quality of the available health economic evidence is useful for identifying aspects where there is room for improvement in future asthma cost-effectiveness studies.

Objective : Asthma educational interventions have been shown to improve several clinically and economically important outcomes. However, these interventions are costly in themselves and could lead to even higher disease costs. A cost-effectiveness threshold analysis would be helpful in determining the threshold value of the cost of educational interventions, leading to these interventions being cost-effective. The aim of the present study was to perform a cost-effectiveness threshold analysis to determine the level at which the cost of a pediatric asthma educational intervention would be cost-effective and cost-saving.Methods : A Markov-type model was developed in order to estimate costs and health outcomes of a simulated cohort of pediatric patients with persistent asthma treated over a 12-month period. Effectiveness parameters were obtained from a single uncontrolled before-and-after study performed with Colombian asthmatic children. Cost data were obtained from official databases provided by the Colombian Ministry of Health. The main outcome was the variable “quality-adjusted life-years” (QALYs).Results : A deterministic threshold sensitivity analysis showed that the asthma educational intervention will be cost-saving to the health system if its cost is under US$513.20. Additionally, the analysis showed that the cost of the intervention would have to be below US$967.40 in order to be cost-effective.Conclusions : This study identified the level at which the cost of a pediatric asthma educational intervention will be cost-effective and cost-saving for the health system in Colombia. Our findings could be a useful aid for decision makers in efficiently allocating limited resources when planning asthma educational interventions for pediatric patients.

Background: Young children with older siblings and those who attend day care are at increased risk for infections, which in turn may protect against the development of allergic diseases, including asthma. However, the results of studies examining the relation between exposure to other children and the subsequent development of asthma have been conflicting. Methods: In a study involving 1035 children followed since birth as part of the Tucson Children's Respiratory Study, we determined the incidence of asthma (defined as at least one episode of asthma diagnosed by a physician when the child was 6 to 13 years old) and the prevalence of frequent wheezing (more than three wheezing episodes during the preceding year) in relation to the number of siblings at home and in relation to attendance at day care during infancy. Results: The presence of one or more older siblings at home protected against the development of asthma (adjusted relative risk for each additional older sibling, 0.8; 95 percent confidence interval, 0.7 to 1.0; P=0.04), as did attendance at day care during the first six months of life (adjusted relative risk, 0.4; 95 percent confidence interval, 0.2 to 1.0; P=0.04). Children with more exposure to other children at home or at day care were more likely to have frequent wheezing at the age of 2 years than children with little or no exposure (adjusted relative risk, 1.4; 95 percent confidence interval, 1.1 to 1.8; P=0.01) but were less likely to have frequent wheezing from the age of 6 (adjusted relative risk, 0.8; 95 percent confidence interval, 0.6 to 1.0; P=0.03) through the age of 13 (adjusted relative risk, 0.3; 95 percent confidence interval, 0.2 to 0.5; P<0.001). Conclusions: Exposure of young children to older children at home or to other children at day care protects against the development of asthma and frequent wheezing later in childhood.

Background: Fractional flow reserve (FFR) is routinely used to evaluate coronary stenosis in patients with atrial fibrillation (AF), although no studies currently address its reliability in this particular population. The clinical impact of correct assessment of coronary stenosis in AF is particularly high in light of the antithrombotic therapy imposed by both AF and coronary stenting. Objectives: Given the hemodynamic variability and microvascular dysfunction described in AF, the aim of this study was to evaluate the hyperemic response to intracoronary adenosine in AF in comparison with sinus rhythm (SR). Methods and Results: This retrospective study included 36 patients in AF and 36 patients in SR. The hyperemic curves were derived in a subset of patients where the required information was available (n = 16 AF, n = 10 SR). AF patients presented a hyperemic response after intracoronary administration of adenosine, which was equivalent to SR in terms of magnitude and time to maximal hyperemia. Conclusion: There is equivalent hyperemic response in FFR-guided revascularization in AF versus SR population. Our findings support the use of FFR in evaluating intermediate coronary stenosis in AF.

Small airway dysfunction (SAD) in asthma can be measured by impulse oscillometry (IOS). Usually, the reactance should decrease with decreases in frequency oscillation. Sometimes an upward shift of the curve at low frequencies can be observed together with lower than expected reactance values. The actual value of the reactance at 5 Hz (X5) is calculated by the Sentry Suite application of the Jaeger Master screen iOS system™, providing the corrected X5 parameter (CX5). Our hypothesis is that correction of X5 is common in persistent asthma and it correlates better than X5 with the IOS parameters for evaluating SAD. In this transversal study, we evaluated 507 children (3–18 years old) using IOS-spirometry (Sentry Suite, Vyntus®). Resistance of all airways (R5), reactance area (AX), resonant frequency (Fres), X5, CX5, difference between R5 and R20 (D5-20), and spirometry parameters were analyzed. Reactance inversion and CX5 prevalence by age range was determined. The mean IOS-Spyrometry values in children with and without CX5 were compared, and correlations with each IOS-spirometry parameter in the age groups were performed. CX5 was found in 83.5% of preschool children, 66.2% of schoolchildren, and 43.3% of adolescents (p < 0.001). The means of R5, AX, and D5-20 were significantly higher and FEV1 was significantly lower in children with CX5 (p < 0.05). In all ages, CX5 correlated better than X5 with IOS-spirometry parameters. Reactance inversion and CX5 are frequent in asthmatic children, decrease with age, and correlate more closely than X5 with other IOS-spirometry parameters for evaluating SAD. [ABSTRACT FROM AUTHOR]

Objective: Suboptimal adherence to inhaled corticosteroids (ICs) is an important cause of poor asthma control in pediatric patients. Among the factors that can be most easily changed for enhancing adherence to ICs is a reduction in the dosing frequency, from twice-daily dosing to once-daily dosing. However, no previous studies have reported an economic evaluation comparing once-daily versus twice-daily IC dosing for pediatric asthma. The aim of this study was to compare the cost-effectiveness of once-daily versus twice-daily IC dosing for maintenance treatment of asthma in pediatric patients.Methods: A Markov-type model was developed in order to estimate costs and health outcomes of a simulated cohort of pediatric patients with persistent asthma treated over a 12-month period. Effectiveness parameters were obtained from a systematic review of the literature. Cost data were obtained from official databases provided by the Colombian Ministry of Health. The main outcome was the variable “quality-adjusted life-years” (QALYs).Results: For the base-case analysis, the model showed that compared with twice-daily dosing, once-daily dosing strategy involved lower costs (US$1529.3 versus $1709.1 average cost per patient over 12 months) and the greatest gain in QALYs (0.8284 versus 0.8084 QALYs on average per patient over 12 months), resulting in once-daily dosing strategy being considered dominant.Conclusions: This study shows that compared with twice-daily dosing, once-daily IC dosing for treating pediatric patients with persistent asthma is the dominant strategy because it involves a greater gain in QALYs at lower total treatment cost.

Background: Evidence suggests that general practitioners (GPs) fail to diagnose up to half of common mental disorder cases. Yet no previous research has systematically summarized the evidence in the case of anxiety disorders. The aim of this review was to systematically assess and meta-analyze the diagnostic accuracy of GPs' assisted (i.e., using severity scales/diagnostic instruments) and unassisted (without such tools) diagnoses of anxiety disorders. Methods: Systematic review (PROSPERO registry CRD42013006736) was conducted. Embase, Ovid Journals -Ovid SPMedline, Pubmed, PsycINFO, Scopus,Web of Science, and Science Direct were searched from January 1980 through June 2014. Seven investigators, working in pairs, evaluated studies for eligibility. The quality of included studies was assessed with the Quality Assessment of Diagnostic Accuracy Studies tool version 2 (QUADAS-2). The main outcome measures were sensitivity and specificity of clinical diagnoses of any anxiety disorder. We pooled sensitivity and specificity levels from included studies using bivariate meta-analyses. Results: Twenty-four studies were included in the meta-analysis with a total sample of 34,902 patients. Pooled sensitivity and specificity were estimated at 44.5% (95% CI 33.7-55.9%) and 90.8% (95% CI 87-93.5%). GPs' sensitivity was higher when diagnoses were assisted (63.6%, 95% CI 50.3-75.1%) than when unassisted (30.5%, 95% CI 20.7-42.5%) to the expense of some specificity loss (87.9%, 95% CI 81.3-92.4% vs. 91.4%, 95% CI 86.6-94.6%, respectively). Identification rates remained constant over time (P-value = .998). Conclusions: The use of diagnostic tools might improve detection of anxiety disorders in "primary care." [ABSTRACT FROM AUTHOR]

Introduction: Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis. RSV‐induced bronchiolitis has been associated with preschool wheeze and asthma in cohort studies where the comparison groups consist of healthy infants. However, recent studies identify rhinovirus (RV)–induced bronchiolitis as a potentially stronger risk factor for recurrent wheeze and asthma. Aim: This systematic review and meta‐analysis aimed to compare the associations of RSV‐ and RV‐induced bronchiolitis with the development of preschool wheeze and childhood asthma. Methods: We performed a systematic search of the published literature in five databases by using a MeSH term‐based algorithm. Cohort studies that enrolled infants with bronchiolitis were included. The primary outcomes were recurrent wheeze and asthma diagnosis. Wald risk ratios and odds ratios (ORs) were estimated, along with their 95% confidence intervals (CIs). Individual and summary ORs were visualized with forest plots. Results: There were 38 studies included in the meta‐analysis. Meta‐analysis of eight studies that had data on the association between infant bronchiolitis and recurrent wheeze showed that the RV‐bronchiolitis group were more likely to develop recurrent wheeze than the RSV‐bronchiolitis group (OR 4.11; 95% CI 2.24–7.56). Similarly, meta‐analysis of the nine studies that had data on asthma development showed that the RV‐bronchiolitis group were more likely to develop asthma (OR 2.72; 95% CI 1.48–4.99). Conclusion: This is the first meta‐analysis that directly compares between‐virus differences in the magnitude of virus‐recurrent wheeze and virus‐childhood asthma outcomes. RV‐induced bronchiolitis was more strongly associated with the risk of developing wheeze and childhood asthma. [ABSTRACT FROM AUTHOR]

Introduction. The choice among the different treatments available can have a great impact on the costs of asthma, Objectives. The objective of this study was to estimate the incremental cost-utility ratio of three inhaled corticosteroids (ICs): budesonide (BUD), fluticasone propionate (FP), and ciclesonide, compared to beclomethasone dipropionate (BDP) (the only IC included in the Compulsory Health Insurance Plan of Colombia), Methods. A Markov-type model was developed to estimate costs and health outcomes of a simulated cohort of patients less than 18 years of age with persistent asthma treated over a 12-month period. Effectiveness parameters were obtained from a systematic review of the literature. Cost data were obtained from a hospital´s bills and from the national manual of drug prices. The study assumed the perspective of the national healthcare in Colombia. The main outcome was the variable 'quality-adjusted life years' (QALY), Results. While treatment with BDP was associated with the lowest cost (£106.16 average cost per patient during 12 months), treatment with FP resulted in the greatest gain in QUALYs (0.9325 QALYs). FP was associated with a greater gain in QALYs compared to BUD and ciclesonide (0.9325 vs. 0.8999 and 0.9051 QALYs, respectively) at lower costs (£231.19 vs. £309.27 and £270.15, respectively), thus leading to dominance. The incremental cost-utility ratio of FP compared to BDP was £19,835.28 per QALY, Conclusions. BDP is the most cost-effective therapy for treating pediatric patients with persistent asthma when willingness to pay (WTP) is less than £21,129.22/QALY, otherwise, FP is the most cost-effective therapy.

Introduction Inhaled therapy using a metered-dose inhaler ( MDI) with attached valved holding chamber has been increasingly recognized as the optimal method for delivering bronchodilators for asthma treatment. However, mainly due to the high cost of these valved holding chambers in many developing countries, the use of non-valved spacers is frequent, despite the scarce evidence that supports their efficacy. The aim of this study was to compare the bronchodilator response to albuterol administered by MDI with and without a valved spacer. Methods In a randomized, two-period, two-sequence crossover clinical trial, we analyzed 31 stable asthmatic children (6-18 yrs of age) on two consecutive days, who were randomly assigned to receive 100 μg of albuterol MDI through either a locally produced valved spacer or a non-valved spacer. The next day, a crossover treatment was employed through the use of the other spacer. Spirometry was recorded before and after each albuterol administration. Results As we were not able to identify any sequence or carryover effect, we tested for treatment effects in both periods. No significant differences in the absolute change in FEV1 (0.20 ± 0.17 vs. 0.18 ± 0.16, p = 0.63), FVC (0.07 ± 0.13 vs. 0.07 ± 0.16, p = 0.88), or MMEF (0.49 ± 0.31 vs. 0.43 ± 0.39, p = 0.53) after bronchodilator administration were found between the use of valved and non-valved spacers. Conclusions In stable asthmatic children, albuterol administered through MDI using a non-valved spacer produces a bronchodilator response similar to that of a spacer with a valve that requires an inhalatory opening pressure (with flows between 2 and 32 l/min) that even toddlers with bronchial obstruction can easily generate.

Obstructive sleep apnea syndrome affects 1%–4% of all children worldwide. Currently, diagnosis of obstructive sleep apnea is based on sea‐level guidelines, without taking into account the altitude at which the populations live. It has been shown that at 3,200 m of altitude there is an increase in obstructive events in healthy children aged 7 to 16 years; on the other hand, it is known that SpO2 dispersion between individuals becomes wider as altitude increases, a phenomenon that is more marked during sleep. About 17 million Colombians live in regions between 2,500 m and 2,700 m, as do significant populations in other Latin American countries. This research aimed to characterize respiratory polygraphy sleep parameters in healthy, non‐snoring children aged 4–9 years living at 2,560 m. We carried out home respiratory polygraphy in 32 children with a mean age of 6.2 years (range 4–9 years). The average recorded sleep time was 7.8 h, the median apnea–hypopnea index was 9.2/h, the obstructive apnea–hypopnea index had a median of 8.8/h (p5 4.2 to p95 17.9) and central apnea a median of 0.4/h. The median SpO2 was 93% (p5 90.5 to p95 94) and transcutaneous CO2 had a median of 39.4 mmHg (p531.7 to p95 42.3). The median oxygen desaturation index ≥ 3% was 11.2 and median oxygen desaturation index ≥ 4% was 3.9. Normal measurements for respiratory polygraphy obtained at sea level do not apply to children at altitude. If such guidelines are used, obstructive sleep apnea will be over‐diagnosed, resulting in unnecessary adenotonsillectomies, among other interventions. [ABSTRACT FROM AUTHOR]

Background: The interplay between COVID‐19 pandemic and asthma in children is still unclear. We evaluated the impact of COVID‐19 pandemic on childhood asthma outcomes. Methods: The PeARL multinational cohort included 1,054 children with asthma and 505 non‐asthmatic children aged between 4 and 18 years from 25 pediatric departments, from 15 countries globally. We compared the frequency of acute respiratory and febrile presentations during the first wave of the COVID‐19 pandemic between groups and with data available from the previous year. In children with asthma, we also compared current and historical disease control. Results: During the pandemic, children with asthma experienced fewer upper respiratory tract infections, episodes of pyrexia, emergency visits, hospital admissions, asthma attacks, and hospitalizations due to asthma, in comparison with the preceding year. Sixty‐six percent of asthmatic children had improved asthma control while in 33% the improvement exceeded the minimal clinically important difference. Pre‐bronchodilatation FEV1 and peak expiratory flow rate were improved during the pandemic. When compared to non‐asthmatic controls, children with asthma were not at increased risk of LRTIs, episodes of pyrexia, emergency visits, or hospitalizations during the pandemic. However, an increased risk of URTIs emerged. Conclusion: Childhood asthma outcomes, including control, were improved during the first wave of the COVID‐19 pandemic, probably because of reduced exposure to asthma triggers and increased treatment adherence. The decreased frequency of acute episodes does not support the notion that childhood asthma may be a risk factor for COVID‐19. Furthermore, the potential for improving childhood asthma outcomes through environmental control becomes apparent. [ABSTRACT FROM AUTHOR]

The leadless pacemaker is an emerging technology with high efficacy and reduced complications rates. However, due to its novel status, some pitfalls remain to be addressed. We report the case of a 91‐year‐old patient undergoing a Micra pacemaker implantation. During the procedure, the maneuvers required for the adequate deployment of the device led to damaging of the septal tricuspid leaflet, resulting in severe tricuspid regurgitation. This is a severe mechanical complication of the Micra implantation technique, not previously reported in literature. In light of the novelty of the leadless pacemaker, we should remain cautious with regards to potential unreported complications. [ABSTRACT FROM AUTHOR]

Objective: Sleep-disordered breathing (SDB) is highly prevalent in school children with poorly-controlled asthma. However, this association has not been assessed in preschoolers with recurrent wheeze, nor in those at risk for asthma. We hypothesized that preschoolers with asthma risk (positive asthma predictive index [API]) have a higher prevalence of SDB and higher inflammatory biomarkers (blood-hsCRP and urinary-LTE4) levels than those with negative API. Method: Children 2 to 5 years of age with recurrent wheezing were classified as positive or negative API. SDB was determined by the pediatric sleep questionnaire (PSQ) and its subscale (PSQSub6). Demographic characteristics, spirometry, blood hsCRP and urinary LTE4 were assessed. Results: We enrolled 101 preschoolers: 70 completed all measurements, 55.4% were males, mean age 4.07 ± 0.87 years, 45% overweight or obese, 70% had positive API, 87.5% had rhinitis. The prevalence of SDB measured by PSQ was 40.8% and by PSQSub6 was 29.6%. However, the proportion of SDB was similar between positive and negative API groups. The hsCRP (mean ± SD) was higher in the positive than in negative API (3.58 ± 0.58 and 1.32 ± 0.36 mg/L, p = 0.69, respectively); moreover, no differences in urinary LTE4 were found between groups. No correlation of PSQ (+) or PSQSub6 (+) with hsCRP and uLTE4 was found. However, preschoolers with positive API had significantly more post-bronchodilator percentage change in FEF25-75 than negative API (24.14 ± 28.1 vs. 4.13 ± 21.8, respectively, p = 0.01). Conclusions: In preschoolers with recurrent wheezing, we should be investigating for the coexistence of SDB, using early screening methods for detecting those conditions. [ABSTRACT FROM AUTHOR]

In this study, we assessed the psychometric properties of the Spanish Patient-Reported Outcomes Measurement Information System (PROMIS) Depression in an adult population-representative sample from Spain (n = 1,503). We tested unidimensionality and local independence item response theory (IRT) assumptions with confirmatory factor and bifactor models under the exploratory structural equations modeling framework. We evaluated item monotonicity assumption with Mokken scaling analysis. We calibrated the items with an IRT-graded response model and assessed score reliability and test information, and evidence of validity with regard to scores on external measures. To examine differential item functioning by age, sex, education, and country (United States vs. Spain, N = 2,271), we used ordinal logistic regression. Results support compliance with IRT assumptions. We found few signs of differential item functioning: Only one item showed country differential functioning between the United States (n = 768) and Spain, with minimal impact on the overall score. Information values were equivalent to reliabilities over 0.90 from -1 (low depression) to +4 SD (high depression) around the population score mean. Evidence of validity in relation to concurrent measures was supported by the expected correlation pattern with external variables of depression, but higher than expected correlations with anxiety were found. Results indicate that the Spanish version of PROMIS Depression is adequate for assessing and monitoring depression levels in the general population and that PROMIS Depression is especially suitable for cross-national comparisons.

Objective : Previous studies have provided conflicting results about how living in a rural or urban environment influences schoolchildren with asthma and allergic diseases in different ways. The aim of the present study was to evaluate if recurrent wheezing preschoolers from rural or urban areas differ in asthma, allergic diseases, and atopy.Methods : A cross-sectional-study in Rafaela, Argentina, on 143 preschoolers with recurrent wheezing from rural and urban settings was performed (2010-2012). Diagnosis of asthma (by positive asthma predictive index [API]), allergic diseases (rhinitis, dermatitis), and atopy (by skin prick test [SPT], peripheral blood eosinophils, and serum total IgE) were assessed.Results : Preschoolers from rural settings had significantly higher prevalence of vaginal delivery, longer breastfeeding, earlier onset of wheezing, more parental smoking, siblings, shared a bedroom, and more exposure to chemicals used in plant fumigation or farm animals, and unpasteurized milk consumption, in comparison to preschoolers living in urban setting. In contrast, preschoolers from urban areas had significantly higher prevalence of parental history of allergy, positive skin prick test, and positive API. After multivariate analysis adjusting for covariates, maternal smoking [odds ratio (OR) = 3.44] and positive SPT (OR = 5.57) significantly increase the risk of asthma diagnosis (positive API); in contrast, living in rural setting (OR = 0.04), and having more siblings (OR = 0.51) decrease their risk.Conclusions : Recurrent wheezing preschoolers from rural areas had a significant inverse odds of being diagnosed with asthma (type-2 inflammation) when compared to those from urban areas. Exposure to farm animals and consumption of unpasteurized milk might have a role. [ABSTRACT FROM AUTHOR]- Published

Caregiver's or maternal depression has been associated with increased asthma morbidity in children from prosperous nations, but little is known about this link in low and middle-income countries. Objective: To examine if caregiver's depressive symptoms are associated with poor asthma control and abnormal immune responses in school-aged children. Methods: Case-control study of 87 asthmatic children (aged 4–11 years) attending a primary care clinic in an underserved area of Santiago (Chile). Cases were children with poor asthma control (Child Asthma Control Test [cACT] <20 points) and controls were children with adequate asthma control (cACT ≥20 points). The Beck Depression Inventory-II (BDI) and a locally validated family health vulnerability test (SALUFAM) were used to assess caregivers’ depression and family health vulnerability. Serum from participating children was assayed for IFN-γ, IL-4, IL-13, TGF-β, cortisol, and total IgE. Results: The mean (SD) age of study participants was 8.23 (2.15 years), and 55.2% were females. Use of inhaled corticosteroids (ICS), family health vulnerability, and caregiver's depressive symptoms were significantly more common in cases than in controls (65.4% vs. 34.6%,p= 0.003; 41.3% vs. 24.8%,p= 0.07; and 39.1% vs. 19.5%,p= 0.04, respectively). There was no significant difference in the level of any serum biomarkers between groups. In a multivariate analysis, only ICS use was significantly associated with better asthma control (OR = 3.56 [1.34–9.48],p= 0.01). Conclusions: Presence of caregiver's depressive symptoms is associated with poor asthma control among children from an underserved community, but this association was no longer significant after accounting for ICS use.

Aim: Previous studies have suggested that Down's syndrome is an independent risk factor for severe respiratory infection due to respiratory syncytial virus (RSV). We compared the clinical characteristics of children with and without Down's syndrome hospitalised due to RSV.Methods: This retrospective cohort study compared data from hospitalisations due to RSV lower respiratory tract infections (LRTI) in children under 14 years of age with (n = 58) and without (n = 58) Down's syndrome.Results: The Down's group had longer hospital stays than the controls of six versus four days (p < 0.0001), even after adjusting for age, weeks of gestation at birth, presence of asthma, bronchopulmonary dysplasia, haemodynamically significant and nonsignificant congenital heart disease. This difference increased when only children under one year of age were analysed to 11 versus five days (p < 0.0001). Children with Down's syndrome were more likely to be admitted to intensive care unit (43.1% versus 22.4%, p = 0.017), need noninvasive mechanical ventilation (36.2% versus 13.7%, p = 0.005) and be prescribed antibiotics and steroids.Conclusion: Children with Down's syndrome hospitalised due to RSV LRTI had longer hospital stays and worse clinical courses than controls, highlighting the need for RSV prophylaxis for children with Down's syndrome, especially under one year of age.

- Abstract
Consistent with the diversity of Latin America, there is profound variability in asthma burden among and within countries in this region. Regional variation in asthma prevalence is likely multifactorial and due to genetics, perinatal exposures, diet, obesity, tobacco use, indoor and outdoor pollutants, psychosocial stress and microbial or parasitic infections. Similarly, non-uniform progress in asthma management leads to regional variability in disease morbidity. Future studies of distinct asthma phenotypes should follow-up well-characterised Latin American subgroups and examine risk factors that are unique or common in Latin America (eg, stress and violence, parasitic infections and use of biomass fuels for cooking). Because most Latin American countries share the same barriers to asthma management, concerted and multifaceted public health and research efforts are needed, including approaches to curtail tobacco use, campaigns to improve asthma treatment, broadening access to care and clinical trials of non-pharmacological interventions (eg, replacing biomass fuels with gas or electric stoves).

Background We tested whether objectively measured indices of obstructive sleep apnoea (OSA) and sleep quality are associated with coronary artery calcification (CAC) prevalence independent of obesity, a classic confounder. Methods 1465 Multi-Ethnic Study of Atherosclerosis participants (mean age 68 years), who were free of clinical cardiovascular disease, had both coronary CT and in-home polysomnography and actigraphy performed. OSA categories were defined by the Apnea-Hypopnea Index (AHI). Prevalence ratios (PRs) for CAC >0 and >400 (high burden) were calculated. Results Participants with severe OSA (AHI ≥30; 14.6%) were more likely to have prevalent CAC, relative to those with no evidence of OSA, after adjustment for demographics and smoking status (PR 1.16; 95% CI 1.06 to 1.26), body mass index (1.11; 1.02 to 1.21) and traditional cardiovascular risk factors (1.10; 1.01 to 1.19). Other markers of hypoxaemia tended to be associated with a higher prevalence of CAC >0. For CAC >400, a higher prevalence was observed with both a higher arousal index and less slow-wave sleep. Overall, associations were somewhat stronger among younger participants, but did not vary by sex or race/ethnicity. Conclusions In this population-based multi-ethnic sample, severe OSA was associated with subclinical coronary artery disease (CAC >0), independent of obesity and traditional cardiovascular risk factors. Furthermore, the associations of the arousal index and slow-wave sleep with high CAC burden suggest that higher nightly sympathetic nervous system activation is also a risk factor. These findings highlight the potential importance of measuring disturbances in OSA as well as sleep fragmentation as possible risk factors for coronary artery disease. [ABSTRACT FROM AUTHOR]

Background Vitamin D deficiency and single nucleotide polymorphisms ( SNP) in the gene encoding vitamin D receptor ( VDR) have been associated with asthma. Objective To compare 25-hydroxyvitamin D (25 OHD) levels and the frequency of 3 SNPs in the VDR gene between asthmatic and healthy children. Methods In persistent asthmatic and healthy control children, the 25 OHD levels were measured using radioimmunoassay and SNPs (FokI, ApaI, and TaqI) were analyzed by a PCR - RFLP assay. Relevant medical history was collected. Results About 75 asthmatic (median age: 9.1 years) and 227 healthy children (10.3 years) were studied. In the whole population, the proportion of sufficient, insufficient, and deficient levels of 25 OHD were 14.9%, 44%, and 41.1%, respectively. 25 OHD sufficiency status was similar in asthmatic and healthy children (p = 0.57). However, the proportion of 25 OHD sufficient levels among asthmatics according to the Global Initiative for Asthma treatment steps 2, 3, and 4 was significantly different (8.6%, 16.6%, and 43.7%, respectively , p = 0.046). All patients on step 4 of the treatment (16/16) were heterozygous for the C allele (FokI VDR SNP). There was a lower presence of the C allele among asthmatics in step 2 (30/33), step 3 (16/24), and controls (45/50), p = 0.007, but this significance did not persist after logistic regression. No significant differences in ApaI and TaqI were found. Conclusions We found a possible association of vitamin D sufficiency status and FokI C allele with higher requirement of therapy to reach asthma control, suggesting that it may be involved in treatment response. Variations in VDR might also play a role in the 25 OHD levels. [ABSTRACT FROM AUTHOR]

Background Chest physiotherapy has been used to treat children hospitalised with pneumonia with no clear scientific evidence to support a beneficial effect. The objective of the current study was to evaluate the efficacy of chest physiotherapy as an adjuvant treatment in children hospitalised with acute community-acquired pneumonia. Methods Children (aged 1-12 years) with a clinical and confirmed radiological diagnosis of pneumonia sequentially admitted to a tertiary children hospital were eligible for this study. Participants were randomly selected to receive a standardised respiratory physiotherapy ( positioning, thoracic vibration, thoracic compression, positive expiratory pressure, breathing exercises and forced exhalation with the glottis open or 'huffing') three times daily in the 'intervention group' or a non-mandatory request to breathe deeply, expectorate the sputum and maintain a lateral body position once a day in the 'control group'. The primary outcomes were reduction in respiratory rate and severity score (respiratory rate, recession, fever, oxygen saturation and chest x-ray) from baseline to discharge. Secondary outcome was duration of hospitalisation. Results In all, 72 patients were randomly allocated to the intervention (n=35) or control (n=37) groups. There were no differences at admission on severity of pneumonia between groups. Respiratory rate and severity score significant decreased between admission to discharge within each group; however, there were no differences when comparing groups. Also, there was no significant difference in duration of hospitalisation between the control and intervention groups (6 vs 8 days, p=0.11, respectively). Conclusions This clinical trial suggests that, in children hospitalised with moderate community-acquired pneumonia, chest physiotherapy did not have clinical benefits in comparison to control group.

Introduction. In the exercise challenge test (ECT), a drop in forced expiratory volume in the first second (FEV1) of between 10 and 15% is the determinant variable for a diagnosis of exercise-induced bronchospasm. Hypothesis. The use of FEV1 plus mean forced expiratory flow between 25% and 75% of the forced vital capacity (FEF25-75%) may increase the sensitivity of the ECT in asthmatic children. Specific objective. To compare FEV1 and FEF25-75% changes in a group of asthmatic and healthy children. Methodology. This was a cross-sectional study. Asthmatics were categorized by their severity (GINA) and after 1 month without controller therapy, an ECT was done under standard protocol. As well, a questionnaire about rhinitis and asthma was conducted with the entire population. ROC curves were used for analysis. Results. A total of 147 children (34 healthy and 113 asthmatics, 18 and 58 males, respectively) were evaluated. Divided into healthy children and intermittent, mild and moderate persistent asthmatics, they had similar average ages (9.4, 9.48, 8.97, and 11.2 years, respectively). Using a 15% fall in FEV1, we obtained 29% sensitivity and 100% specificity. However, when we used a 10% fall in FEV1, sensitivity was 47% and specificity was 97%. Adding a 28% fall in FEF25-75%, sensitivity was 52% and specificity was 94%. Conclusion. This study suggests that test sensitivity can increase by using a lower FEV1 cut-off (10%) and adding a 28% fall in FEF25-75%. [ABSTRACT FROM AUTHOR]
