概括
艾滋病毒感染者患肺气的风险更高. 新的肺功能测试 (PFT) 标准,包括1秒强迫呼吸量/强迫生命能力 (FEV1/FVC) 的比率和残留量,可以更好地识别艾滋病毒感染者的肺气.
科学领域:
- 肺部病理学 肺部病理学
- 传染性疾病 传染性疾病
- 放射学 放射学是一门学科.
背景情况:
- 与没有艾滋病毒的人相比,艾滋病毒感染者 (PWH) 面临着近两倍的肺气风险.
- 与艾滋病毒相关的肺免疫变化可能会导致显著的放射性肺瘤模式和空气流量限制.
- 传统的肺功能测试 (PFT) 标准可能无法充分捕捉PWH中的肺气.
研究的目的:
- 为了调查PFT测量空气流限制的PWH与无放射性肺瘤的PFT测量中的差异.
- 确定特定的PFT措施和值,以区分PWH中的肺气.
主要方法:
- 在乔治亚州亚特兰大进行的前性队列研究 (2013年7月至2018年6月).
- 对167个PWH的PFT和胸部计算机断层扫描 (CT) 数据的分析.
- 二进制递归分区用于识别对肺的歧视性PFT措施.
主要成果:
- 在该队列中,53% (89/167) 的PWH患有放射性肺瘤.
- 气泡与PFTs上空气流限制的可能性增加有关.
- 使用FEV1/FVC比率为0.78和残留体积为116%的新分区预测发现了94%的PWH患有肺气,超过了传统的FEV1/FVC比率0.7 (55%的识别).
结论:
- 在PWH中的肺瘤在PFT上表现出独特的空气流量限制模式.
- 传统的肺气诊断标准对于PWH可能是不够的.
- 需要进一步的研究来验证诊断与艾滋病毒相关的肺气的新门.

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.

Chronic Obstructive Pulmonary Disease-I: Introduction
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.

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
