通过饮食炎症指数 (DII) 衡量的促炎症饮食与更高的喘患病率有显著联系. 改变饮食以减少炎症可能有助于预防和治疗喘.
科学领域:
- 营养科学 营养科学
- 流行病学 流行病学
- 呼吸系统医学 呼吸系统医学
背景情况:
- 炎症在喘发育中起着至关重要的作用.
- 饮食模式显著影响全身炎症反应.
- 了解饮食和喘之间的联系对于公共健康至关重要.
研究的目的:
- 调查饮食炎症指数 (DII) 与喘患病率之间的关联.
- 探索DII和喘风险之间的剂量反应关系.
- 检查各种人口和生活方式子组之间的这种关联.
主要方法:
- 国家健康和营养检查调查 (NHANES) 数据 (1999-2018) 的横截面分析.
- 包括37,283名美国成年人,记录了人口,饮食和健康信息.
- 多变量逻辑回归和受限立方线 (RCS) 分析以评估DII-喘关联和非线性.
主要成果:
- 在较高的DII得分和喘患病率增加之间发现了显著的积极关联 (OR,1.05;95%CI,每1个SD增加1.02-1.09).
- RCS分析显示出非线性关系 (p=0.0026),风险明显增加超过1.366.6的DII.
- 分层分析通常支持大多数子组的积极关联.
结论:
- 在促炎症饮食 (DII) 和喘之间存在显著的非线性关联.
- 减轻炎症的饮食修改是预防和治疗喘的一个潜在策略.
- 对影响喘的特定饮食成分的进一步研究是有必要的.

Asthma-I: Introduction
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma: Pathogenesis and Management
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.
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
Asthma-IV: Diagnostic and Management
Clinical Assessment for Asthma:
This is the first step in diagnosing and managing asthma. It includes:
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
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...
