概括
这项研究开发了综合性肺部严重性评分 (IPSS),通过结合呼吸功能,症状和心理健康来评估慢性阻塞性肺部疾病 (COPD) 的严重性. IPSS有助于识别独特的精神呼吸表型,以更好地分层患者的风险.
科学领域:
- 肺部医学和精神病学
- 生物统计学和健康信息学
背景情况:
- 在慢性阻塞性肺病 (COPD) 中,一秒内强迫呼气量 (FEV1) 不完全解释症状变化和预后.
- 焦虑和抑郁在COPD中很普遍,但很少被纳入复合严重程度指数中.
研究的目的:
- 开发和内部验证一个综合性肺部严重性评分 (IPSS).
- 将呼吸功能,症状负担和情绪状态结合到COPD评估的单一分数中.
主要方法:
- 在罗马尼亚两所三级医疗中心对390名COPD患者进行前性观察研究.
- 使用螺旋计 (预测FEV1%),mMRC呼吸障碍量表,COPD评估测试 (CAT),医院焦虑和抑郁量表 (HADS) 和认知测试 (MoCA,MMSE).
- 开发了PulmoScore (CAT,mMRC,呼吸器缺陷) 并使用基于HADS的精神病学乘法器将其扩展到IPSS;使用光谱聚类,后勤回归,MLP和LIME进行表型和验证.
主要成果:
- 确定了两个表型:精神呼吸和主要呼吸,前者表现出较低的FEV1%,较高的症状负担 (CAT,mMRC) 和增加的焦虑/抑郁.
- IPSS有效地捕获了精神呼吸系统的表型,后勤回归和MLP实现了0.89准确度和0.95AUC.
- IPSS值将患者分为四组,与增加的呼吸和情感负担相关.
结论:
- IPSS整合了呼吸和情感维度,提供了比COPD中单独的螺旋测量更好的严重性评估.
- 评分有助于识别临床相关的精神呼吸系统表型,表明可能增加风险分层.
- IPSS可以从例行测量中计算出来,并且与可解释的AI兼容,因此需要进一步的外部和纵向验证.

4.0K
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.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
