概括
用肺超声波 (LUS),生物阻抗光谱 (BIS) 和下静脉缩指数 (IVC-CI) 检测到的透析儿童的亚临床高血与左心室缩 (LVH) 有关. 这种多参数方法有助于早期检测和评估心脏并发症的风险.
科学领域:
- 儿科脏病学 儿科脏病学
- 心血管生理学心血管生理学
- 诊断成像 诊断成像 诊断成像
背景情况:
- 儿科透析患者的液体过载会导致严重的心脏问题,如左心室缩 (LVH) 和功能障碍.
- 持续的亚临床高血,在临床上表现为euvolemia,但在技术上表现为高血,缺乏对其心血管影响的彻底调查.
- 这项试点研究通过探索在接受透析的儿童中检测亚临床高血及其心脏影响的方法来弥补这一差距.
研究的目的:
- 评估肺超声波 (LUS),生物阻抗光谱学 (BIS) 和下静脉缩性指数 (IVC-CI) 在识别慢性透析儿童的亚临床高血方面的联合实用性.
- 调查亚临床高血量症和心脏并发症之间的关联,特别是左心室缩 (LVH).
主要方法:
- 一项纵向研究涉及23名接受慢性透析的儿童.
- 每两个月定期评估液体状况,使用体检,LUS,IVC-CI和BIS.
- 每6个月进行一次心声扫描以评估心脏参数.
主要成果:
- 在临床evolemic患者中,在隔离式体重增加和LUS B线 (R=0.2923,p<0.001) 和BIS OH/ECW (R=0.4144,p<0.001) 之间发现了显著的相关性.
- 在透析间体重增加和IVC-CI之间观察到负相关性 (R=-0.2597,p=0.019).
- 亚临床高血压与高血压危机 (67%对0%,p<0.01) 和LVH (75%对27%,p=0.04) 的更高发病率有关.

Longitudinal Studies
526
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
13.3K
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...

Dialysis
1.4K
Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Dialysis
1.8K
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Pilot and Numeric Relaying
492
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:
