背景情况:
- 川崎病 (KD) 是一种危急的儿科疾病,导致冠状动脉病变 (CAL).
- 静脉注射免疫球蛋白 (IVIG) 耐药性是KD管理中的一个重要并发症.
- 确定可靠的生物标志物来预测这些结果对于及时干预至关重要.
研究的目的:
- 系统地审查和元分析川崎病预后营养指数 (PNI) 的诊断价值.
- 评估KD患者中PNI和IVIG耐药性之间的关联.
- 评估 PNI 与 KD 中 CAL 的发展之间的关系.

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
92
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
