Lungs were considered as sterile for a long time. However, it is now evident that the lungs of healthy people are colonized by microorganisms. Among the bacteria present in the pulmonary microbiota, a significant proportion is anaerobic (strict or facultative). Even though interest in the pulmonary microbiota is increasing, few studies have focused on these unknowns that represent the lung resident anaerobic bacteria. This review describes the biodiversity of anaerobes in physiological conditions, and in different chronic respiratory diseases (cystic fibrosis, COPD, asthma)...

In 2014, the Request for Applications from the National Institutes of Health (NIH) for continued funding of a multi-site clinical and mechanistic research network, Inner City Asthma Consortium (ICAC), called for "efficient IRB review and approval for multi-center studies" and "IRB approval within 30 days from submission". These requirements were precursors to the NIH policy of single IRB review for multi-site studies. Here we share our challenges, implementation processes, results, and recommendations, using a single, independent IRB...

Interleukin-33 (IL-33) belongs to the IL-1 cytokine family and plays an important role in modulating immune system by inducing Th2 immune response via the ST2 membrane receptor. Epithelial cells are the major producers of IL-33. However, IL-33 is also secreted by other cells, e.g., bone marrow cells, dendritic cells, macrophages, and mast cells. IL-33 targets a broad range of cell types bearing the ST2 surface receptor. Many ST2-positive cells, such as Th2 cells, mast cells, basophils, and eosinophils, are involved in the development of allergic bronchial asthma (BA)...

A small subgroup of patients with asthma suffers from severe disease that is either partially controlled or uncontrolled despite intensive, guideline-based treatment. These patients have significantly impaired quality of life and although they constitute <5% of all asthma patients, they are responsible for more than half of asthma-related healthcare costs. Here, we review a definition for severe asthma and present all therapeutic options currently available for these severe asthma patients. Moreover, we suggest a specific algorithmic treatment approach for the management of severe, difficult-to-treat asthma based on specific phenotype characteristics and biomarkers...

Introduction: High asthma prevalence in Latin-American cities is thought to be caused by poor hygiene and infections. This contradicts the widely accepted 'hygiene hypothesis' for asthma aetiology. Methods: Systematic review of observational studies evaluating the association between poor hygiene exposures or infections and asthma/wheeze among Latin-American children aged 4-16 years. MEDLINE, EMBASE, LILACS and CINAHL electronic databases were searched following a predefined strategy to 18 December 2017...

Wheezing and cough are common case scenarios that pediatricians encountered in their office practices. Although a bronchogenic cyst is an uncommon condition, it is essential to be considered in the differential diagnosis of a chronic cough and wheezing among young children who fail to respond to appropriate medical treatment. A 28-month-old girl was referred to our pediatric pulmonology clinic with persistent symptoms of a cough and wheeze unresponsive to standard asthma therapy. This presentation prompted us to undertake a detailed diagnostic evaluation...

Chronic obstructive pulmonary disease (COPD) is often misdiagnosed and inappropriately treated in many patients. COPD is a distinct disease from adult-onset asthma; however, some patients with COPD may present with several forms of airway disease described as asthma-COPD overlap (ACO). Bronchodilators and inhaled corticosteroids (ICS) both have a place in standard maintenance treatment of COPD and asthma; however, recommendations for use differ widely. In patients with COPD, long-acting bronchodilators are effective initial monotherapy treatment, while ICS monotherapy is recommended as initial treatment in patients with asthma...

Asthma is the most common chronic pediatric condition. Effective asthma management requires a proactive and inclusive approach that controls the patient's symptoms and prevents recurrence of exacerbations. Clinicians should encourage patients to become involved in their management since self-management approaches have proven to be an effective means for chronic illness treatment. Novel forms of self-monitoring and management are technological interventions. In the last decade, novel technology has been developed and used to improve asthma control since it is a powerful agent that addresses a variety of challenges in chronic disease management such as education, communication and adherence...

OBJECTIVES: A variable proportion of patients presenting to the emergency department (ED) with acute asthma require admission to hospital. Previous studies have identified select factors associated with admission following ED presentation; however, no review has synthesized the evidence in this regard. This systematic review summarizes the evidence regarding factors associated with hospital admission following ED presentation. METHODS: Searches were conducted in seven electronic databases and common sources of grey literature...

Asthma and chronic obstructive pulmonary disease (COPD) are widely documented diseases with an inflammatory component. Asthma is a heterogeneous disorder of the airways that involves chronic inflammation, decline of the airway function and tissue remodeling. Chronic obstructive pulmonary disease is a preventable and treatable disease, which is characterized by persistent limited airflow, and is usually progressive with an increased inflammatory response in the airways. The inflammatory response is evoked by the stimulus of noxious particles and gases...

Although the prominent role of the microbiome in human health has been established, the early-life microbiome is now being recognized as a major influence on long-term human health and development. Variations in the composition and functional potential of the early-life microbiome are the result of lifestyle factors, such as mode of birth, breastfeeding, diet, and antibiotic usage. In addition, variations in the composition of the early-life microbiome have been associated with specific disease outcomes, such as asthma, obesity, and neurodevelopmental disorders...

BACKGROUND: Asthma exacerbations in school-aged children peak in autumn, shortly after children return to school following the summer holiday. This might reflect a combination of risk factors, including poor treatment adherence, increased allergen and viral exposure, and altered immune tolerance. Since this peak is predictable, interventions targeting modifiable risk factors might reduce exacerbation-associated morbidity and strain upon health resources. The peak occurs in September in the Northern Hemisphere and in February in the Southern Hemisphere...

INTRODUCTION: The standardized patient (SP) has assumed a fundamental role in undergraduate medical education since first conceived over 50 years ago. While widely used in student training and assessment of communication and clinical examination across health disciplines, little is known how SPs enhance knowledge or skill development among professionals. We conducted a systematic review to determine the effectiveness of SPs in continuing medical education (CME) programs. METHODS: Authors independently searched for studies published between 1966 and 2016, describing CME initiatives using SP encounters as practice for participants compared with those which did not...

Respiratory syncytial virus (RSV) is a common pathogen that infects virtually all children by 2 years of age and is the leading cause of hospitalization of infants worldwide. While most children experience mild symptoms, some children progress to severe lower respiratory tract infection. Those children with severe disease have a much higher risk of developing childhood wheezing later in life. Many risk factors are known to result in exacerbated disease, including premature birth and early age of RSV infection, when the immune system is relatively immature...

INTRODUCTION: The presence of eosinophils in asthma inflammation is a relevant factor in the pathophysiology of the disease, however the relationship between the blood eosinophil count (BEC) with asthma severity and prognosis is still under debate. The aim of this work is to analyze the relationship between the BEC levels and hospital readmissions in patients with asthma. MATERIAL AND METHODS: A review was retrospectively carried out on all admissions of patients over 18 years old due to exacerbation of asthma occurring in our hospital between the years 2000 and 2010...
