概括

在怀孕早期,高且稳步增加的雌激素 (E2) 水平与流产风险较低有关. 这一发现表明,E2监测可能有助于评估早期怀孕的风险.

科学领域:

生殖内分泌学生殖内分泌学
产科和妇科产科和妇科
围产儿医学围产儿医学

背景情况:

怀孕早期的雌激素 (E2) 水平对于成功的孕期至关重要.
了解E2轨迹模式可以提供对流产风险的见解.
鉴定早期怀孕丧失风险较高的女性具有临床意义.

研究的目的:

调查早期怀孕雌激醇 (E2) 轨迹模式与早期流产风险之间的关联.
在自然受孕的妇女中,在怀孕早期识别出不同的E2配置文件.
评估E2轨迹对早期怀孕结果的预测价值.

主要方法:

对527名自然受孕妇女进行了回顾性研究,并在怀孕12周内至少进行了三次E2测量.
基于组的轨迹建模以识别不同的E2模式.
多变量逻辑回归和子组分析,以评估E2轨迹与早期流产风险之间的关联.

主要成果:

确定了四个不同的E2轨迹.
轨迹3 (稳步增加的高水平) 与轨迹2 (缓慢增加的低水平) 相比,与早期流产风险显著降低相关 (aOR=0.24,p<0.001).

Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Infertility in Females

Infertility in Females

Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
