概括
怀孕早期较高的体力活动与胎盘生长因子 (PlGF) 的增加有关,胎盘生长因子 (PlGF) 是预子症风险的关键生物标志物. 这表明,中度至强度的体力活动可能会积极影响子宫前的发展.
科学领域:
- 产科和妇科 产科和妇科
- 预防医学 预防医学
- 怀孕的生物标志物
背景情况:
- 产前 (PE) 查涉及母亲的危险因素,平均动脉血压 (MAP),子宫动脉脉动指数 (UtA-PI) 和血清胎盘生长因子 (PlGF).
- 运动干预可以改善怀孕期间的血管功能,潜在地平衡血管性因素.
- 关于久坐不动,体力活动和PE生物标志物之间的关联存在有限的研究.
研究的目的:
- 调查客观测量的身体活动和久坐水平与PE风险生物标志物之间的关系.
- 测试假设,较高的体力活动 (PA) 与较低的MAP和UtA-PI以及较高的PLGF有关.
主要方法:
- 一项辅助研究使用PREVAL队列的便利抽样.
- 通过动图 (GT9X Actigraph) 对21名妇女在怀孕的第一季度进行身体活动和久坐的客观测量.
- 测量PE生物标志物:Uta-PI (超声波),plgf (血清) 和map (sphygmomanometer) 的测量.
- 用T测试或曼·惠特尼U测试进行生物标志物比较,分为活跃/低活跃和静止/低静止的分层.
主要成果:
- 血清PlGF水平在活跃组比低活跃组高57.6% (P=0.018).
- 在活跃和低静止群体中观察到较低的MAP和UtA-PI,尽管在统计学上并不显著.
- 中度至强度的体力活动 (MVPA) 与plgf水平有显著的关联.
结论:
- 客观测量的体力活动,特别是MVPA,与怀孕早期的PLGF水平较高有关.
- 研究结果表明,身体活动与与子宫前风险相关的生物标志物之间存在潜在联系.
- 需要进一步的研究来证实身体活动在预防PE中的作用.

01:30Hypertension III: Clinical Manifestations and Diagnostic Studies
59
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

01:19Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
223
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
