概括
急性部骨折显著增加轴突损伤,特别是在患有痴呆症的个体中. 这表明骨折引起的炎症,血脑屏障的破坏和痴呆症患者的加速脑损伤之间存在联系.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 炎症研究 炎症研究
背景情况:
- 炎症与阿尔茨海默氏症 (AD) 和其他痴呆症有关,但其确切作用尚不清楚.
- 急性全身炎症,如感染或骨折,可以加速痴呆症的进展.
- 该ASCRIBED研究调查了关节骨折,炎症和痴呆症中脑损伤之间的联系.
研究的目的:
- 为了检查急性关节骨折,全身炎症和脑损伤生物标志物之间的关系.
- 为了比较轴突损伤的水平和血脑屏障完整性,在患有和没有痴呆症的患者下,关节骨折.
主要方法:
- 招募了患有痴呆症和关节骨折的参与者,没有痴呆症的关节骨折,以及患有痴呆症但没有急性疾病的对照组.
- 收集脑脊液 (CSF) 和血液样本以测量炎症和脑损伤生物标志物.
- 分析了神经纤维光链 (NFL) 作为轴突损伤标志物和卡尔胺用于血液-中枢神经液屏障透性.
主要成果:
- 关节骨折导致神经丝轻链 (NFL) 水平显著上升,表明轴突损伤增加,特别是在患有同时存在痴呆症的人群中.
- 脑流体NFL水平与血液-脑流体屏障透性 (Qalbumin) 密切相关,这表明轴突损伤和BBB破坏之间存在联系.
- 与其他组相比,患有痴呆症和部骨折的患者表现出最高的NFL水平.
结论:
- 骨折会导致严重的急性轴突损伤,超过稳定痴呆症患者的损伤.
- 在关节骨折后的急性脑损伤的严重程度在患有先前痴呆症的个体中似乎更大.
- 需要进一步的研究来了解这种损伤的机制,并开发治疗性干预措施,治疗与痴呆症中关节骨折相关的脑损伤.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
749
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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
516
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...
