概括
多创伤患者的早期高血清费里水平表明死亡风险增加和器官功能障碍. 在受伤后对费里丁水平的连续监测改善了风险分层,从而改善了患者的治疗结果.
科学领域:
- 危急护理医学
- 创伤手术
- 生物标志物研究
背景情况:
- 严重的多创伤是全球死亡和残疾的主要原因.
- 超血是严重疾病的一个已知的生物标志物.
- 在多重创伤中超血的预后价值尚不清楚.
研究的目的:
- 在多创伤患者中研究血清费里的时间动态.
- 评估费里水平与全身炎症,器官功能障碍和死亡率之间的关联.
- 开发和验证用于预测多创伤患者的死亡率的预后表.
主要方法:
- 在四个创伤中心对1475名多创伤患者进行前性观察队列研究.
- 血清费里含量测定在治疗第一天和第七天.
- 根据费里丁值分层,逻辑回归,ROC分析,并整合费里丁,炎症标志物 (IL-6,CRP) 和临床评分 (SOFA,APACHE II) 的诺莫格拉姆开发.
主要成果:
- 在39. 3%的患者中观察到超血 (≥500 ng/ mL),随着蛋白水平的提高,死亡率显著增加 (蛋白≥3000 ng/ mL高达66. 7%).
- 第7天的费里水平 (AUC 0. 807) 比第1天的水平 (AUC 0. 686) 更高,以预测死亡率.
- 铁素> 1000 ng/ ml 是一个独立的死亡风险因素,与炎症,器官功能障碍和凝血病相关. 幸存者表现出更的费里廷下降.
结论:
- 多创伤患者的早期超血是不良结果的重要预测因素,反映了全身炎症和器官衰竭.
- 伤害后的连续费里丁监测增强了风险分层,并有助于指导重症监护.
- 费里丁作为一种实用生物标志物,用于识别高风险多创伤患者,并为目标干预提供信息.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
213
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...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
331
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
