- 儿童发育医学
- 药理学
背景情况:
- 非常早产的婴儿面临神经发育障碍的风险.
- 皮质类固醇用于控制这些婴儿的炎症.
- 早期的德克萨米他与不良结果有关,导致皮的使用增加,但其长期影响尚不清楚.
研究的目的:
- 在极度早产婴儿中研究产后皮质类固醇治疗对神经发育的长期影响.
- 评估6. 5岁后的认知结果与皮和甲暴露的关系.

主要方法:
- 一项试点研究对66名极早产婴儿进行了6年半的跟踪.
- 记录了皮和甲的累积剂量.
- 使用标准化智力测试来评估认知功能.
主要成果:
- 治疗组和未治疗组之间没有发现平均智力系数 (全尺度,表现,口头) 的显著差异.
- 在接受皮质类固醇治疗的组中观察到较高的认知障碍发病率,尽管在统计学上不显著.
- 44% 的儿童接受皮质类固醇治疗.
结论:
- 高剂量的产后皮质类固醇可能与长期的不良认知影响有关.
- 进一步的纵向研究对于证实皮质类固醇治疗的安全性至关重要.

COPD: Management Using Bronchodilators and Corticosteroids
300
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...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
200
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
382
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
