概括
一项新的研究表明,在怀孕早期诊断维生素D缺乏症的门较低,根据副甲状腺激素 (PTH) 调节,发现其发生在15.76 ng/mL. 这一修订的切断线确定了66.1%的印度孕妇患有VDD,强调需要重新评估当前的诊断标准.
科学领域:
- 生殖内分泌和新陈代谢
- 孕产妇和胎儿的医学
- 营养生物化学
背景情况:
- 在全球范围内,维生素D缺乏的高患病率与不良的妊娠和分娩结果有关.
- 目前对于妊娠中VDD的诊断截止值 (<20 ng/ ml血清25- 维生素- D) 缺乏共识.
- 评估VDD的诊断截止值至关重要,特别是在印度妇女等特定人群的早期怀孕中.
研究的目的:
- 在看似健康的印度妇女中评估怀孕早期维生素D缺乏的诊断截止点.
- 确定副甲状腺激素 (PTH) 被最大限度抑制的血清25-基维生素-D (25(OH) D度的断点.
- 在这个群体中确定与VDD相关的因素.
主要方法:
- 涉及395名看似健康的印度孕妇,孕期≤14周的横截面研究.
- 收集人口,产科,人体测量数据和血清样本以测量OH) D和PTH.
- 分段回归分析以确定最大PTH抑制的25 ((OH) D断点;对VDD关联的共变量分析.
主要成果:
- 显著的PTH增加与下降的OH) D的突破点为15. 76 ng/ ml (95% CI: 12. 3 - 19. 2).
- 使用这一值,66. 1% 的女性患有VDD,而当前< 20 ng/ mL的值为82. 0%.
- VDD与季节性 (冬季,季风后),贫血和体力活动水平有显著关联.
结论:
- 在怀孕早期的VDD诊断截止值 (15. 76 ng/ mL) 低于目前的建议.
- 评估维生素D状况是复杂的,因为可修改和不可修改的因素如平价,贫血,季节和活性.
- 需要使用纵向研究重新评估现有的VDD切断值,以确定与不良妊娠结果的因果关系.

Hormones and Bone Tissue
2.9K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

The Parathyroid Glands
2.5K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Role of Skin in Vitamin D Synthesis
5.6K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Skeleton and Calcium Homeostasis
4.8K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Synthesis and Functions of Calcitonin
2.4K
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
