概括
减少对颗粒物 (PM) 的暴露,并使用室内空气过,在沙漠沙尘暴 (DDS) 期间显著改善了儿童的喘控制和肺功能. 这种综合方法为管理污染环境中的儿童喘提供了一个有希望的策略.
科学领域:
- 环境健康 环境健康
- 儿科肺病学 儿科肺病学
- 过敏和免疫学 过敏和免疫学
背景情况:
- 人为或沙漠尘埃来源的高颗粒物度与儿童喘发病率的增加有关.
- 沙漠沙尘暴 (DDS) 构成严重的环境健康风险,特别是对于患有喘的儿童来说.
研究的目的:
- 评估暴露减少策略在沙漠沙尘暴 (DDS) 季节对儿童喘控制的影响.
- 评估室内空气过的有效性与减少暴露的建议相结合.
主要方法:
- 一项随机对照试验,涉及塞浦路斯和希腊182名患有喘的小学儿童.
- 干预组包括:没有干预 (控制),减少户外暴露 (警报,室内停留) 和联合干预 (户外减少加室内HEPA空气过).
- 使用儿童喘控制测试 (c-ACT),螺旋计 (FEV1,FVC) 和分数呼出的氧化 (FeNO) 来测量喘控制.
主要成果:
- 与对照组相比,联合干预组的c-ACT得分显著改善 (p=0.007).
- 在联合干预组内,亚托皮性儿童的改善更为明显 (p=0.047).
- 在预测FEV1% (p=0.025) 中观察到显著的改善,减少了对喘药物的需求,并且在组合组中减少了非计划的诊所访问.
结论:
- 减少暴露的建议和室内空气过可以有效地改善生活在高颗粒物污染地区的儿童的喘症状控制.
- 这些策略也可能导致改善肺功能和减少在DDS事件期间对儿童喘的医疗保健利用.

Asthma-I: Introduction
2.6K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
297
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Asthma: Pathogenesis and Management
398
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
