概括
怀孕前母亲的维生素D (25-氧维生素D) 含量较低,与更高的孕前风险有关. 这种关联可能受到体重指数的影响,这表明预先设定的维生素D优化是关键.
科学领域:
- 生殖内分泌学 生殖内分泌学
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 营养科学 营养科学
背景情况:
- 孕前是全球孕产妇和婴儿发病的一个重要原因.
- 母亲的维生素D状况越来越被认为是妊娠结果的潜在因素.
- 优化怀孕前的健康状况对于减少妊娠并发症至关重要.
研究的目的:
- 为了研究母体血清25-氧维生素D[25(OH) D]水平与孕前症风险之间的关联.
- 为了检查维生素D水平测量在怀孕前和怀孕早期 (8周).
主要方法:
- 对前性,双盲,安慰剂控制的EAGeR试验的二次分析 (N=552).
- 用强大的标准误差进行日志-二项式回归以估计风险比率 (RR) 和95%置信区间 (CI).
- 逆概率权重用于调整受限于活产婴儿的分析中的选择偏差.
主要成果:
- 与足够水平 (≥30 ng/ml) 相比,怀孕前维生素D缺乏 (≤20 ng/ml) 的女性患孕前的风险更高 (RR:2.32).
- 这种关联在调整身体质量指数 (BMI) 和其他共变量 (RR: 1.45) 后得到减弱.
- 在怀孕8周的维生素D水平或不充分的孕前水平之间没有发现显著的关联.
结论:
- 缺陷的25(OH) D水平可能与先兆子风险的增加有关,部分由BMI调解.
- 孕前期是优化母亲维生素D状况以减少产前风险的关键窗口.
- 在怀孕之前改善母亲的营养状况可能会为产前提供一种新的预防策略.

137.5K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
