概括
新的研究定义了"骨质疏松症",这是一种老年男性的低骨密度状态,患骨折的风险很高. 这项研究提出了特定的T-score和QCT BMD值,用于识别东亚和高加索男性的骨质疏松症.
科学领域:
- 老年学是指老年学的学科.
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
背景情况:
- 与老年女性相比,老年男性在较高的股骨部T-score下经历部脆弱性骨折 (FFx).
- 现有的骨矿物质密度 (BMD) 类别可能无法充分捕捉老年男性骨折风险.
研究的目的:
- 为年长的男性增加部FFx风险提出一个新的低BMD状态类别,称为"骨质疏松症".
- 根据部部T-分数和腰椎 (LS) 定量计算断层扫描 (QCT) BMD,在高加索和东亚男性中建立骨质疏松症的特定诊断门.
主要方法:
- 对年长的高加索和东亚男性的股骨部T分数和LS QCT BMD的分析.
- 在性别和种族之间比较骨折预测的BMD值.
- 关于特定T-score和QCT BMD值的建议,以定义骨质疏松症.
主要成果:
- 骨质疏松症被定义为年长的高加索男性的股骨部T-score ≤ -2.0和年长的东亚男性的T-score ≤ -2.1.
- 建议的骨质疏松症值:LS DXA T-score ≤ -2.5 (东亚男性) 和 ≤ -2.0 (高加索男性);LS QCT BMD < 68 mg/mL (东亚男性) 和 < 100 mg/mL (高加索男性).
- 在东亚男性中,LS QCT BMD < 68 mg/mL 对检测脊椎FFx的敏感度为77%.
结论:
- 骨质疏松症 (Osteofrailia) 是一项拟议的新类别,用于识别低骨质量和高部FFx风险的老年男性.
- 建议使用特定的T-score和QCT BMD值来诊断不同族群男性的骨质疏松症.
- 需要进一步的研究来调查LS QCT BMD和男性部FFx风险之间的关系.

z Scores and Unusual Values
11.0K
The z score is one of the three measures of relative standing. It describes the location of a value in a dataset relative to the mean. z scores are obtained after the standardization of the values in a dataset. The z score for the mean is 0.
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Professional Values
10.5K
Nurses are responsible for caring for patients during birth, death, illness, and healing. Professional values guide the decisions and actions that nurses make in their careers. If nurses know the decisions and actions to take, providing patients with exceptional care is possible.
The values that are the foundation of the nursing profession are altruism, autonomy, human dignity, and social justice.
First, altruism refers to the concern for the welfare and well-being of others without personal...

Critical Values
10.2K
A critical value is a definite value obtained from a particular probability distribution at a predecided confidence level (or a predecided significance level) for a given population parameter. The critical value provides demarcation that separates the sample statistics that are likely to occur from the ones that are unlikely to occur based on the given probability distribution and the population parameter to be estimated. The critical value for normal distribution is obtained from the z...

Introduction to z Scores
11.0K
A z score (or standardized value) is measured in units of the standard deviation. It tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a zero z score. It is important to note that the mean of the z scores is zero, and the standard deviation is one.
