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...

BACKGROUND AND OBJECTIVE: The Airways Disease Endotyping for Personalized Therapeutics (ADEPT) study profiled mild, moderate and severe asthma, and non-atopic healthy controls. We explored this dataset to define Type-2 inflammation based on airway-mucosal IL-13-driven gene expression and how this related to clinically-accessible biomarkers. METHODS: IL-13-driven gene expression was evaluated in several human cell lines. We then defined Type-2 status in 25 healthy subjects, 28 mild, 29 moderate, and 26 severe asthmatics, based on airway-mucosal expression of 1) CC-motif chemokine ligand (CCL)-26, (the most differentially expressed gene), 2) periostin, or 3) a multi-gene IL-13 in-vitro signature (IVS)...

INTRODUCTION: Phenotypic overlap between the two main chronic airway pulmonary diseases, asthma and chronic obstructive pulmonary disease (COPD), has been the subject of debate for decades, and recently the nomenclature of asthma-COPD overlap syndrome (ACOS) was adopted for this condition. The definition of this entity in the literature is, however, very heterogeneous, it is therefore important to define how it applies to Portugal. METHODS: A literature review of ACOS was made in a first phase resulting in the drawing up of a document that was later submitted for discussion among a panel of chronic lung diseases experts, resulting in reflexions about diagnosis, treatment and clinical guidance for ACOS patients...

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...

INTRODUCTION: Myocardial perfusion imaging (MPI) is widely used in the evaluation of known and suspected coronary artery disease (CAD). Imaging of heart in stress and rest enables the comparison of myocardial uptake of radiotracer in proportion to the needs and coronary flow, which is used for detection of perfusion defects. Exercise stress and pharmacologic agents are used for the stressing purpose. Novel pharmacologic stressor regadenoson is A2A selective adenosine agonist, which selectively binds to the adenosine receptors in coronary arteries causing coronary dilatation...

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...

BACKGROUND: Bulbus Fritillaria cirrhosa D. Don (BFC) has been used in China as a folk medicine for the treatment of cough and asthma for more than 2000 years. The antitussive and antiasthmatic effects of BFC have been reported before, nevertheless its toxicity and safety have not been documented. This study investigated the possible effects of BFC on spindle assembly checkpoint (SAC), mitotic fidelity and genomic stability in human NCM460 colon epithelial cells. METHODS: Cells were treated with BFC (0, 20, 40, 80 and 160μg/ml) for 24, 48 and 72h and harvested differently according to the biomarkers observed...
