概括
前臂双能X射线吸收度 (DXA) 有效地区分了初级绝经后骨质疏松症与初级副甲状腺症 (PHPT) 相关的骨质疏松症. 前臂DXA还显示了PHPT患者与水平的独立关联.
科学领域:
- 内分泌学 在内分泌学.
- 骨的新陈代谢 骨的新陈代谢
- 诊断成像 诊断成像 诊断成像
背景情况:
- 原发性偏甲状腺症 (PHPT) 可能导致骨质疏松症,这可能很难区分于初级绝经后骨质疏松症.
- 双能X射线吸收计 (DXA) 是骨质疏松症诊断的标准工具,但其在区分PHPT相关的骨损失方面的实用性需要进一步评估.
研究的目的:
- 评估前臂DXA在区分绝经后骨质疏松症和PHPT后来的骨质疏松症的有效性.
- 调查前臂骨矿物质密度 (BMD) 测量和PHPT的临床特征之间的关系.
主要方法:
- 一项回顾性研究涉及246名接受PHPT的女性和100名患有骨质疏松症/骨质疏松症的绝经后对照.
- 分析了腰椎,部和远距离半径的DXA扫描.
- 在PHPT和对照组之间以及在绝经前和绝经后的PHPT子组之间比较DXA测量和临床/生化数据.
主要成果:
- 骨质疏松症在PHPT组中明显更为普遍,特别影响远距离半径 (p < 0.001).
- 前臂 (远半径) DXA T-分数在区分PHPT相关的骨质疏松症与初级绝经后骨质疏松症方面显示出出色的区分值 (AUC>0.80).
- 在绝经前PHPT患者中,血清水平与远半径T分数 (B = -0.594) 独立相关.
结论:
- 前臂DXA是区分PHPT相关骨质疏松症和初级绝经后骨质疏松症的一个有价值的工具.
- 在DXA上减少的远半径BMD应该促使考虑PHPT,即使诊断主要是生物化学的.
- 这些发现可能有助于确定患有PHPT的绝经后妇女骨质疏松症的主要原因.

01:16Muscles that Move the Forearm
4.0K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

01:16Muscles of the Forearm that Move the Hand and Fingers
2.7K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

00:56Density
20.0K
Density is an important characteristic of substances, crucial in determining whether an object sinks or floats in a fluid. Its SI unit is kg/m3, and its cgs unit is g/cm3. The density of an object helps in identifying its composition, and also reveals information about the phase of the matter and its substructure. The densities of liquids and solids are roughly comparable, consistent with the fact that their atoms are in close contact. However, gases have much lower densities than liquids and...

01:21Current Density
5.2K
The total amount of current flowing through one unit value of a cross-sectional area is referred to as current density. If the current flow is uniform, the amount of current flowing through a conductor is the same at all points along the conductor, even if the conductor area varies. The current density consists of the local magnitude and direction of the charge flow, which varies from point to point. Current density is measured in amperes per meter square, and direction is defined as the net...

01:20Strain-Energy Density
935
Understanding the strain energy density in materials under axial load is crucial for evaluating their mechanical behavior and durability. When a rod is subjected to such a load, it elongates and stores energy, known as strain energy, as potential energy within the material. This energy is measured in terms of energy per unit volume.
In the elastic region of a material, the relationship between the stress and the strain is linear and follows Hooke's Law. The strain energy density in this region...

01:22Bulk Density of Aggregate
1.2K
Bulk density refers to the mass of aggregate particles that would fill a unit volume. The concept of bulk density originates from the inability to pack aggregate particles in a manner that completely eliminates void spaces. Hence, the term bulk refers to the volume that encompasses both the aggregates and the voids. This measurement is crucial when aggregates are batched by volume and is used to convert quantities by mass to volume.
