概括
身体活动 (PA) 的下降与膝关节骨关节炎 (KOA) 症状的恶化有关. 活动减少,特别是在下午晚些时候和晚上,与两年来KOA严重程度的增加相关.
科学领域:
- 整形外科 整形外科 整形外科
- 生物医学工程 生物医学工程
- 老年学是指老年学的学科.
背景情况:
- 膝关节关节炎 (KOA) 是导致残疾的主要原因.
- 身体活动 (PA) 对于管理KOA至关重要,但PA水平的变化及其对症状进展的影响尚未完全理解.
- 可穿戴的加速度计在日常生活中提供了对PA的客观测量.
研究的目的:
- 在两年内调查客观测量的体力活动 (PA) 变化与膝关节骨关节炎 (KOA) 症状进展之间的关联.
- 确定与恶化的KOA相关的PA下降的特定模式.
主要方法:
- 利用了782名参与骨关节炎倡议加速仪子研究的数据.
- 评估PA使用部佩戴的ActiGraph加速度计,分析每日计数和每3小时间隔在不同强度水平上花费的时间.
- 参与者被分类为"恶化" (WOMAC评分增加>10分) 或在两年内"稳定".
主要成果:
- 15.7%的参与者经历了KOA症状的恶化.
- 与"稳定"组相比",恶化"组的每日PA总数下降幅度更大 (-18%vs-10%).
- 在"恶化"组中,在下午晚些时候和晚上 (15:00-21:00) 观察到PA显著降低 (-21%对比-6%).
- 恶化的KOA与步行速度降低,坐站时间增加以及更大程度上缩小中间关节空间的趋势有关.
结论:
- 整体体身体活动的较大减少,特别是在下午晚些时候和晚上,与膝关节骨关节炎症状的恶化有关.
- 虽然无法最终确定因果关系,但这些发现强调了在KOA管理中保持一致的PA水平的重要性.
- 客观的PA监测可能有助于识别 KOA 进展风险较高的个体.

Longitudinal Studies
537
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Longitudinal Research
13.5K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Initiation of Translation
39.2K
Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs.
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

Knee Joint
3.3K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...
