概括
矯正矯正學的系統性評論通常在沒有新的證據的情况下更新,當新研究被添加時,它們往往具有偏見的高風險. 提高研究质量对于有效的基于证据的实践至关重要.
科学领域:
- 基于证据的牙科.
- 研究方法研究方法论.
- 系统审查是系统的审查.
背景情况:
- 系统审查 (SR) 需要定期更新以纳入新的证据.
- 更新SR是资源密集型,需要优先考虑高质量的研究.
- 评估证据数量,质量和近期的趋势对于正统牙科SR更新至关重要.
研究的目的:
- 评估包括在正义牙科系统性审查更新中的证据数量,质量和最新性的趋势.
- 为了确定影响偏差风险的因素,包括在正义牙科系统性审查中的试验.
主要方法:
- 识别了多个版本的正义牙科系统审查,来自Cochrane数据库.
- 记录了每次审查更新的试验数量,偏差风险和发表年份.
- 采用多变量回归来分析影响试验偏差风险的因素及其在SR中的比例.
主要成果:
- 分析了45个系统性审查和更新;每次审查的试验数量随着时间的推移而增加.
- 15.6%的评论没有证据,而40.74%的更新没有添加新的证据.
- 超过一半 (57.3%) 的初级研究具有高偏差风险,在更新中略有改善;试验年龄,而不是出版年份,影响了偏差风险较低的比例.
结论:
- ортодонтика系统评价经常更新,没有纳入新的证据.
- 系统性审查中新包含的证据往往具有高偏差风险.
- 需要采取战略干预措施来提高研究质量,并优化系统审查的资源配置.

Osteoclasts in Bone Remodeling
2.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Remodeling
38.2K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
