Background Asthma control falls short of current goals of asthma management guidelines. Non-invasive monitoring of airway inflammation may help to improve the level of asthma control in children. Aim 1) To identify a set of exhaled volatile organic compounds (VOCs) that is most predictive for an asthma exacerbation in children. 2) To determine the chemical background of predictive VOCs. Methods In an one-year prospective observational study, 96 asthmatic children were studied . At clinical visits with an interval of 2 months, asthma control, fractional exhaled nitric oxide, lung function (FEV1, FEV1/VC) and VOCs in exhaled breath were determined by means of gas chromatography time-of-flight mass spectrometry...

BACKGROUND: There are no nationally representative population-based studies investigating the relationship between physical activity, chronic conditions and multimorbidity (i.e., two or more chronic conditions) in low- and middle-income countries (LMICs), and studies on a multi-national level are lacking. This is an important research gap, given the rapid increase in the prevalence of chronic diseases associated with lifestyle changes in these countries. This cross-sectional study aimed to assess the association between chronic conditions, multimorbidity and low physical activity (PA) among community-dwelling adults in 46 LMICs, and explore the mediators of these relationships...

BACKGROUND AND OBJECTIVE: Reduction of critical asthma management time can reduce intensive care utilization. The goal of this study was to determine whether a Critical Asthma Standardized Clinical Assessment and Management Plan (SCAMP) can decrease length of critical asthma management time. METHODS: This retrospective study compared critical asthma management times in children managed before and after implementation of a Critical Asthma SCAMP. The SCAMP used an asthma severity score management scheme to guide stepwise escalation and weaning of therapies...

OBJECTIVE: Hospitalizations for acute asthma are thought to be highly preventable through the use of efficacious medications, though many patients have poor metered-dose inhaler (MDI) technique, lessening these medications' real-world effectiveness. Teaching MDI technique during hospitalization may therefore lead to improved outcomes. However, MDIs may be underutilized to deliver short-acting β-agonists in the inpatient setting, despite equivalent efficacy to nebulizer delivery. We sought to characterize delivery methods of short-acting beta-agonist (SABA) therapy among hospitalized patients with acute asthma to understand if there are missed opportunities for self-management education...

The incidence of asthma has increased markedly since the 1960s and is currently estimated to affect more than 300 million individuals worldwide. A number of environmental factors are implicated in asthma pathogenesis, one of which is vitamin D. Vitamin D deficiency is a global health concern and has increased in parallel with asthma incidence. Epidemiological studies report associations between low vitamin D status, assessed as circulating levels of 25-hydroxyvitamin D, with asthma incidence, severity, exacerbations and responses to treatment...

PURPOSE OF REVIEW: In this review, we discuss current thinking in relation to available guidelines for the care of preschool-aged children with recurrent wheezing, while highlighting the gaps in our knowledge and discussing changes that could occur over the next 5 years. RECENT FINDINGS: The Asthma Predictive Index as well as allergen-specific IgE, peripheral eosinophil count and exhaled nitric oxide are perhaps underutilized sources of information that can assist in predicting progression to asthma and response to therapies...

Among pulmonary vascular diseases, pulmonary hypertension (PH) is the best studied and has been the focus of our work. The current classification of PH is based on a relatively simple combination of patient characteristics and hemodynamics. This leads to inherent limitations, including the inability to customize treatment and the lack of clarity from a more granular identification based on individual patient phenotypes. Accurate phenotyping of PH can be used in the clinic to select therapies and determine prognosis and in research to increase the homogeneity of study cohorts...

2,4,6-trihydroxy-3-geranyl acetophenone (tHGA) is a synthetic compound that is naturally found in Melicope ptelefolia. We had previously demonstrated that parenteral administration of tHGA reduces pulmonary inflammation in OVA-sensitized mice. In this study, we evaluated the effect of orally administered tHGA upon airway remodeling in a murine model of chronic asthma. Female BALB/C mice were sensitized intraperitoneally with ovalbumin (OVA) on day 0, 7 and 14, followed by aerosolized 1% OVA 3 times per week for 6 weeks...

Occupational exposure is an important, global cause of respiratory disease. Unlike many other non-communicable lung diseases, the proximal causes of many occupational lung diseases are well understood and they should be amenable to control with use of established and effective approaches. Therefore, the risks arising from exposure to silica and asbestos are well known, as are the means of their prevention. Although the incidence of occupational lung disease has decreased in many countries, in parts of the world undergoing rapid economic transition and population growth-often with large informal and unregulated workforces-occupational exposures continue to impose a heavy burden of disease...

Asthmatic children are at risk for respiratory failure and should be appropriately treated before transport. The objectives were to find out if the Pediatric Advanced Life Support guidelines for asthma treatment were followed in the emergency department (ED); to determine if additional treatment during transport or within the first 2 hours of admission was needed; and to compare the management of intubated asthmatics by the ED, transport team, and the intensive care unit (ICU) physician. The records for children diagnosed with acute asthma over 7 years who were transported by the intensive care transport team were reviewed...

BACKGROUND: Because of time and cost constraints, objective classification of atopic and nonatopic asthma has been limited in large epidemiologic studies. However, as we try to better understand exposure-outcome associations and ensure appropriate treatment of asthma, it is important to focus on phenotype-defined asthma classification. OBJECTIVE: To compare atopic and nonatopic asthma in rural children with regard to risk factors and clinical outcomes. METHODS: We conducted a cross-sectional study in rural Saskatchewan, Canada, in 2011...

Enabling patients with asthma to obtain the knowledge, confidence and skills they need in order to assume a major role in the management of their disease is cost effective. It should be an integral part of any plan for long-term control of asthma. The modified Patient Enablement Instrument (mPEI) is an easily administered questionnaire that was adapted in the United Kingdom to measure patient enablement in asthma, but its applicability in Portugal is not known. Validity and reliability of questionnaires should be tested before use in settings different from those of the original version...

In recent decades, both asthma prevalence and incidence have been increasing worldwide, not only due to the genetic background, but mainly because of the effect of a wide number of environmental and lifestyle risk factors. In many countries noncommunicable diseases, like asthma, are not yet considered a healthcare priority. This review will analyze and discuss disparities in asthma management in several countries and regions, such as access to healthcare human resources and medications, due to limited financial capacity to develop strategies to control and prevent this chronic disease...

The Global Asthma Network (GAN), established in 2012, followed the International Study of Asthma and Allergies in Childhood (ISAAC). ISAAC Phase One involved over 700 000 adolescents and children from 156 centres in 56 countries; it found marked worldwide variation in symptom prevalence of asthma, rhinitis and eczema that was not explained by the current understanding of these diseases; ISAAC Phase Three involved over 1 187 496 adolescents and children (237 centres in 98 countries). It found that asthma symptom prevalence was increasing in many locations especially in low- and middle-income countries where severity was also high, and identified several environmental factors that required further investigation...

BACKGROUND: Inhaled short-acting anticholinergics (SAAC) and short-acting beta₂-agonists (SABA) are effective therapies for adult patients with acute asthma who present to the emergency department (ED). It is unclear, however, whether the combination of SAAC and SABA treatment is more effective in reducing hospitalisations compared to treatment with SABA alone. OBJECTIVES: To conduct an up-to-date systematic search and meta-analysis on the effectiveness of combined inhaled therapy (SAAC + SABA agents) vs...

Bronchopulmonary dysplasia (BPD) is a chronic lung disease most commonly seen in premature infants who required mechanical ventilation and oxygen therapy for acute respiratory distress. While advances in neonatal care have resulted in improved survival rates of premature infants, limited progress has been made in reducing rates of BPD. Lack of progress may in part be attributed to the limited therapeutic options available for prevention and treatment of BPD. Several lung-protective strategies have been shown to reduce risks, including use of non-invasive support, as well as early extubation and volume ventilation when intubation is required...

INTRODUCTION: An extrafine combination of beclometasone dipropionate (BDP) and formoterol fumarate (FF) via a pressurised metered-dose inhaler (pMDI) has been commercially available for some years for the management of asthma and chronic obstructive pulmonary disease (COPD). A dry powder inhaler (DPI) formulation of extrafine BDP/FF is now also available. This study evaluated the cardiovascular safety of BDP/FF DPI in comparison to BDP/FF pMDI and placebo. METHODS: Single-dose, partially-blind, randomised, placebo-controlled, 5-period crossover study...
