概括
中性粒细胞与淋巴细胞的比率 (NLR) 可能有助于识别患有缺血性中风后中风后 (PSE) 风险的患者. 较高的NLR名义上与发展PSE有关,这需要进一步研究炎症.
科学领域:
- 神经学 神经学
- 炎症研究的研究.
- 发现生物标志物的发现.
背景情况:
- 脑卒中后 (PSE) 是缺血性脑卒中的一个重要并发症.
- 早期识别患有PSE风险的患者仍然是一个临床挑战.
- 系统性炎症标志物可以提供有关发病的过程的见解.
研究的目的:
- 调查中性粒细胞与淋巴细胞的比率 (NLR),血小板与淋巴细胞的比率 (PLR) 和血红蛋白与淋巴细胞的比率 (HLR) 与PSE的发展之间的关联.
- 探索这些炎症标志物在预测PSE风险中的有用性.
主要方法:
- 对1445名因急性缺血性中风住院的成年患者的回顾性分析.
- 从血液计数计算NLR,PLR和HLR,在入院后2天内进行.
- 使用竞争性风险模型评估与PSE发展的关联,平均随访时间为7年.
主要成果:
- 在7年内,2.98%的患者患上了PSE.
- 在PSE组中,中位数NLR显著高于PSE组 (3.45对2.94).
- 持续的NLR与PSE名义上相关 (SHR=1.048,p=0.040);NLR>7显示PSE发病率增加 (SHR=2.20,p=0.024).
- PLR和HLR没有显示与PSE的关联.
- PSE患者的死亡率更高,住院时间更长.
结论:
- 中性粒细胞与淋巴细胞的比率 (NLR) 是一种随时可用的炎症标志物,名义上与PSE发展有关.
- 这些探索性发现表明,系统性炎症在中风后的发育过程中可能发挥作用.
- 需要进一步的研究来验证NLR作为PSE的预测生物标志物.

Regulation of Stroke Volume
4.7K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Cardiac Output and Stroke Volume
4.5K
Cardiac output (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.

Cardiac Output II: Effect of Stroke Volume on Cardiac Output
3.2K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Relative Risk
2.0K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Inflammatory Response
16.1K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Association Areas of the Cortex
9.0K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
