概括
随着COVID-19大流行,支气管炎的模式发生了变化,其他病毒,如鼻病毒和流感变得越来越突出. 呼吸道同胞性病毒 (RSV) 仍然很常见,但在某些情况下不那么严重.
科学领域:
- 儿科 儿科 儿科
- 传染性疾病 传染性疾病
- 流行病学 流行病学
背景情况:
- 支气管炎是一种常见的婴儿LRTI,历史上由RSV主导.
- 随着COVID-19的流行,人们对改变LRTI的流行病学和临床表现产生了担忧.
研究的目的:
- 分析COVID-19流行病对支气管炎流行病学和严重程度的影响.
- 为了比较两个连续的支气管炎季节的病毒病因和临床结果.
主要方法:
- 对患有支气管炎住院的儿科患者的回顾性分析.
- 两个季节的比较:2021-2022年和2022-2023年.
- 收集的数据包括病毒病原体,住院时间,临床严重程度和呼吸支持.
主要成果:
- 在这两个季节,RSV的流行率都很高,但其他病毒 (犀牛病毒,流感) 在2022-2023年显著增加.
- 支气管炎发病率转移到11月的早期峰值.
- 与非RSV病例相比,RSV相关的支气管炎在2022-2023年没有增加严重程度.
结论:
- 疫情重塑了支气管炎的流行病学,非RSV病毒感染的增加.
- 减少的流行病限制可能促进了其他呼吸道病毒的传播.
- 虽然RSV仍然很重要,但其在严重支气管炎中的作用可能相对于其他病原体而言正在减少.

1.6K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

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...

2.8K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

01:30Pneumonia I: Introduction
238
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
