- 喘研究 喘研究
- 肥胖与健康 肥胖与健康
背景情况:
- 流行病学研究将喘患者的超重/肥胖与增加症状严重程度和恶化联系起来.
- 呼吸道过敏反应 (AHR) 是喘的一个关键特征,通过直接挑战测试显示与体重指数 (BMI) 有混合关联.
- 儿童群体中喘控制评估需要进一步调查,特别是关于AHR和BMI.
研究的目的:
- 调查身体质量指数 (BMI) 与儿童喘控制之间的关联.
- 通过曼尼托尔挑战测试,使用间接气道高响应 (AHR) 来评估喘控制.

主要方法:
- 一项涉及80名被诊断患有喘的儿童 (年龄在6-18岁) 的横截面研究.
- 使用喘控制测试 (ACT) 问卷进行了自我评估.
- 气道过敏反应 (AHR) 的严重程度使用曼尼托尔挑战测试进行了评估.
主要成果:
- 超过50%的参与者表现出AHR,尽管报告了良好的喘控制 (ACT得分≥20).
- 中度AHR与FEV1和FEV1/FVC略有降低有关,但BMI与AHR严重程度没有显著相关.

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
229
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...

Asthma: Pathogenesis and Management
329
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.

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...
