概括
骨质强度指数 (BMSi) 在加勒比海西班牙裔,非西班牙裔黑人和非西班牙裔白人之间没有差异. 这表明,与区域性骨硬化不同,骨材特性不能解释骨折风险的种族差异.
科学领域:
- 整形外科 整形外科 整形外科
- 骨生物学 骨生物学 骨生物学
- 老年学是一门学科.
背景情况:
- 骨折风险的种族差异仍然存在,尽管考虑了面积骨矿物质密度 (aBMD).
- 用DXA测量的aBMD无法捕捉骨材质的特性,这可能会影响骨折风险.
- 有限的研究存在于骨材特性中的种族/种族差异,特别是包括西班牙裔人口.
研究的目的:
- 在加勒比海西班牙裔 (CH),非西班牙裔黑人 (NHB) 和非西班牙裔白人 (NHW) 个人中调查骨质强度指数 (BMSi) 的种族/种族差异.
- 确定BMSi是否有助于解释骨折风险中的种族/民族差异.
主要方法:
- 利用冲击微印记测量了华盛顿高地因伍德社区衰老项目参与者的BMSi (N=148).
- 跨种族/族群 (CH,NHB,NHW) 的比较BMSi.
- 对年龄,性别,BMI,骨折状况,糖尿病,酒精消耗,吸烟和骨质疏松症治疗进行调整的分析.
主要成果:
- 在CH,NHB和NHW参与者之间没有观察到BMSi的显著差异 (p > 0.22).
- 在调整多个共同变量 (p > 0.47) 后,这些发现保持一致.
- 在BMSi方面,没有发现种族和糖尿病状况之间的显著相互作用.
结论:
- 衡量骨材强度的BMSi在加勒比海西班牙裔,非西班牙裔黑人和非西班牙裔白人中是相似的.
- 根据BMSi的评估,骨质强度的差异似乎无法解释骨折风险的已确定的种族/民族差异.

Bone Disorders
5.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Changes in the Appendicular Skeleton with Age
3.9K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Classification of Bones
10.8K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Stereotypes, Prejudice, and Discrimination
95.9K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Spongy Bone
9.1K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Bias in Epidemiological Studies
1.5K
Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
