概括
补充omega-3脂肪酸 (n-3PUFA) 和多种微量营养素显著降低了健康老年人的炎症. 这种干预措施对有炎症饮食的老年人和晚年人群最有效.
科学领域:
- 老年学是一门学科.
- 营养免疫学 营养免疫学
- 生物化学 生物化学
背景情况:
- 衰老的特点是慢性低度炎症,通常由低水平的抗炎微量营养素加剧.
- 关键的抗炎微量营养素包括长链omega-3脂肪酸 (n-3PUFA),维生素D,叶酸和可巴胺,这些在老年人群中经常缺乏.
研究的目的:
- 研究12周多微量营养素和n-3PUFA补充剂对健康老年人炎症生物标志物的影响.
- 为了确定补充剂是否会影响综合INFLA得分,以及效应是否会根据年龄和饮食炎症指数 (E-DII) 变化.
主要方法:
- 一项随机,双盲,安慰剂控制的研究,涉及112名健康,身体活跃的老年人 (平均年龄75.6岁).
- 干预组接受了生理剂量的叶酸,科巴胺,胆酸和n-3PUFA (EPA+DHA).
- 营养状况和炎症的生物标志物 (INFLA评分,E-DII) 被评估.
主要成果:
- 在干预组中观察到Omega-3指数,血清25-hydroxycholecalciferol,红细胞叶酸和全转胺的显著增加.
- 与安慰剂相比,多微量营养素+n-3PUFA补充剂显著降低了INFLA得分 (P = .036).
- 观察到INFLA得分在老年参与者和支持炎症的背景饮食 (更高的E-DII) 和年龄较大的参与者中降低得多.
结论:
- 多微量营养素和n-3PUFA补充剂有效地减少健康老年人的低级炎症.
- 抗炎作用在具有促炎饮食模式的老年人和老年人中更为明显.
- 这种补充策略在老年人群中管理炎症方面表现有前途.

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

The Effect of Aging on Tissues
2.5K
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...
