概括
表观遗传年龄 (EA),生物衰老的衡量标准,与成人脊柱形手术中的术后并发症有关. 与时间学年龄相比,EA的增加预测了更高的不良结果风险,这表明EA是风险分层的潜在生物标志物.
科学领域:
- 生物标志物 生物标志物
- 表观遗传学 在表观遗传学中,表观遗传学是指表观遗传学.
- 外科手术的结果
背景情况:
- 成年脊柱形 (ASD) 手术的并发症率很高 (37-71%),特别是在老年人群中.
- 年代年龄和脆弱性得分是已知的预测因素,但可能无法完全捕捉生物脆弱性.
- 表观遗传年龄 (EA),来自DNA甲基化,可能更好地反映生理储备和应激反应能力.
研究的目的:
- 为了确定表观遗传年龄 (EA) 是否与成人脊柱形 (ASD) 手术中的早期术后并发症有关.
- 研究EA作为ASD患者风险分层的潜在生物标志物.
主要方法:
- 对30名接受ASD手术的患者进行前性队列研究.
- 使用Illumina EPIC v2.0阵列对外围血液单核细胞 (PBMC) 的DNA甲基化分析.
- 使用Horvath DNAmAge算法计算EA,并评估其与术后并发症,时间年龄 (CA) 和埃德蒙顿脆弱指数 (EFI) 的关联.
主要成果:
- 47%的患者在30天内出现了术后并发症.
- EA大于CA的患者的并发症发生率明显更高 (86%对14%,P=0.038).
- 在并发症组中,EA和CA之间的差异显著更大 (5.07年对0.87年,P=0.029).
结论:
- 在ASD患者的术后并发症与表观遗传改变和相对于CA的EA升高有关.
- 在ASD外科手术中,EA可以作为手术前风险分层的新生物标志物.
- 需要进一步的研究来验证EA在临床实践中的实用性.

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

The Effect of Aging on Tissues
3.4K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Changes in the Appendicular Skeleton with Age
3.4K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Pharmacodynamics in Geriatric Patients: Effects of Age
191
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
230
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
