科学领域:
- 类风湿病学 类风湿病学
- 传染性疾病 传染性疾病
- 肺部病理学 肺部病理学
背景情况:
- 类风湿性关节炎 (RA) 可以表现为肺部疾病 (RA-LD),包括间歇性肺部疾病 (RA-ILD) 和支气管病变 (RA-BR).
- 对于RA-LD对严重感染风险的影响仍然不完全理解.
研究的目的:
- 调查类风湿性关节炎相关肺病 (RA-LD) 与严重感染风险之间的关联.
- 为了区分RA-ILD和RA-BR亚型之间的感染风险.
主要方法:
- 使用MGB生物库进行的回顾性队列研究.
- 对221名RA-LD患者 (151名RA-ILD,70名RA-BR) 与980名RA-no LD对照进行了比较,根据年龄,性别和RA持续时间进行了匹配.
- 严重感染作为主要结局,使用与Fine和Gray模型调整的倾向得分调整的分发危险比率 (sdHR) 进行分析.
主要成果:
- 与RA-no LD对照组相比,RA-LD患者的严重感染风险显著增加 (sdHR为1.60).
- RA-ILD与严重感染风险的增加密切相关 (sdHR1.79),而RA-BR显示出非显著的趋势 (sdHR1.19).

Chronic Obstructive Pulmonary Disease

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...

Pneumonia I: Introduction
331
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.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
