概括
在老年患者中,较短的手术前端粒长度 (TL) 可能预测术后妄 (POD). 较长的TL与POD风险降低有关,这表明TL是潜在的生物标志物.
科学领域:
- 老年学是一门学科.
- 关键护理医学 关键护理医学
- 分子生物学分子生物学
背景情况:
- 端粒长度 (TL) 和术后妄 (POD) 与衰老和炎症有关.
- 较短的TL是已知的细胞衰老和炎症增加的标志物.
- POD是老年手术患者的常见并发症,与不良结果有关.
研究的目的:
- 为了研究手术前端粒长度与术后狂妄症的发展之间的关联.
- 确定手术前TL是否可以作为老年患者POD的预测生物标志物.
主要方法:
- 一项前性观察试点研究,涉及50名65岁以上的患者.
- 包括需要至少两天重症监护室 (ICU) 住院的患者.
- 测量了手术前的TL,并使用重症监护 Delirium 查清单 (ICDSC) 评估POD.
主要成果:
- 10名患者患有POD (POD组),而40名患者没有 (非POD组).
- 最初,两组之间没有观察到手术前TL的显著差异 (p=0.104).
- 然而,多变量分析显示,经过对年龄和MMSE评分进行调整后,手术前TL≥309,110 RLU/μg DNA与POD风险降低有显著关联 (aOR:0.132;p=0.047).
结论:
- 较短的手术前端粒长度与老年患者患术后痴呆症的风险增加有关.
- 手术前的TL可能是POD的潜在预测生物标志物,特别是在调整年龄和认知功能之后.
- 需要更大的样本规模研究来证实这些发现并探索潜在的机制.

Long-term Depression
2.6K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Replicative Cell Senescence
3.7K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...
