概括
血清脂质水平,包括甘油三和胆固醇,在双胞胎怀孕期间上升. 较高的体重指数 (BMI) 与妊娠糖尿病 (GDM) 和妊娠并发症高血压疾病 (HDCP) 有关,而HDL-C可能会提供保护.
科学领域:
- 产科和妇科 产科和妇科
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 内分泌学 在内分泌学.
背景情况:
- 与单子妊娠相比,双胞胎怀孕带来了独特的生理挑战.
- 妊娠期间血清脂质谱的变化很常见,但在双胞胎怀孕中可能会发生变化.
- 孕期糖尿病 (GDM) 和妊娠并发症的高血压疾病 (HDCP) 是双胞胎怀孕的重大风险.
研究的目的:
- 为了描述双胞胎怀孕期间血清脂水平的动态变化.
- 调查血清脂质概况与双胞胎怀孕中GDM和HDCP的发展之间的关联.
- 探索早期怀孕脂质水平和体重指数 (BMI) 对GDM和HDCP的预测价值.
主要方法:
- 追溯分析297例双胞胎怀孕,收集人口统计和医学数据.
- 血清脂质水平 (甘油三,总胆固醇,LDL-C,HDL-C) 测量在第一,第二和第三个三个月.
- 多变量回归和决策树模型用于评估脂质水平,BMI和妊娠并发症 (GDM,HDCP) 之间的关联.
主要成果:
- 三甘油 (TG),总胆固醇 (TC) 和LDL-C从第一到第三季度显著增加;HDL-C在第三季度下降.
- 怀孕早期的TC升高与GDM和HDCP有关. 在第二个三个月内,在HDCP组中观察到更高的TG.
- 妊娠前BMI的增加与GDM和HDCP独立相关. 第三个三个月的HDL-C变化与GDM和HDCP风险有关.
结论:
- 血清脂类水平在双胞胎怀孕期间呈现逐渐增加,在GDM和HDCP中观察到特定的变化.
- 怀孕前的BMI是双胞胎怀孕中GDM和HDCP的重要独立风险因素.
- 高密度脂蛋白胆固醇 (HDL-C) 可能起到对GDM和HDCP的保护作用;对早期脂质预测的进一步研究是有必要的.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
188
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Lipids: Dietary Sources and Requirements
822
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...

Lipid Absorption
516
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Lipid-derived Compounds in the Human Body
4.4K
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin,...
