Asthma is a serious health problem throughout the world. During past two decades, many scientific advances have improved our understanding of asthma and ability to manage control it effectively. However, recommendations for care need be adapted local conditions, resources services. Since was formed in 1993, Global Initiative Asthma, network individuals, organisations public officials, has played leading role disseminating information about patients with based on process continuous review...

Whether vaccination during pregnancy could reduce the burden of respiratory syncytial virus (RSV)–associated lower tract illness in newborns and infants is uncertain. Download a PDF Research Summary. In this phase 3, double-blind trial conducted 18 countries, we randomly assigned, 1:1 ratio, pregnant women at 24 through 36 weeks' gestation to receive single intramuscular injection 120 μg bivalent RSV prefusion F protein–based (RSVpreF) vaccine or placebo.

Respiratory epithelial cells play a crucial role in the inflammatory response during Pseudomonas aeruginosa infection lungs of patients with cystic fibrosis. In this study, we determined whether binding specific gene products (pilin, flagellin) to their receptors on respiratory would result production neutrophil chemoattractant IL-8. Piliated wild-type organisms, purified pili, or antibody pilin receptor (asialoGM1) evoked significant IL-8 by immortalized airway cells, whereas nonpiliated...

Abstract Asthma is the most common chronic lower respiratory disease in childhood throughout world. Several guidelines and/or consensus documents are available to support medical decisions on pediatric asthma. Although there no doubt that use of systematic approaches for management can considerably improve outcomes, dissemination and implementation these still major challenges. Consequently, I nternational C ollaboration Asthma, Allergy Immunology (i CAALL ), recently formed by EAACI , AAAAI...

Abstract Asthma is the most common chronic disease of childhood and leading cause morbidity from as measured by school absences, emergency department visits, hospitalions 1 . During past two decades, many scientific advances have improved our understanding asthma ability to manage control it effectively. However, in children 5 years younger, clinical symptoms are variable non‐specific. Furthermore, neither airflow limitation nor airway inflammation, main pathologic hallmarks condition, can...

Consensus case definitions for childhood tuberculosis have been proposed by an international expert panel, aiming to standardize the reporting of cases in research focusing on diagnosis intrathoracic children. These are intended diagnostic evaluation studies symptomatic children with clinical suspicion tuberculosis, and were not predefine inclusion criteria into such studies. Feedback from researchers suggested that further clarification was required these could be improved. Particular...
