概括
肥胖病因性地降低了基于囊素C的功能 (eGFR),但不是基于肌素的eGFR. 这些发现强调了在评估脏健康和慢性脏病 (CKD) 风险时考虑肥胖的重要性.

背景情况:
- 肥胖与慢性病 (CKD) 的发病和进展有关.
- 肥胖和功能之间的确切因果关系尚不清楚.
- 调查肥胖对估计的淋巴细胞过率 (eGFR) 的因果影响至关重要.
研究的目的:
- 确定肥胖对估计的淋巴细胞过率 (eGFR) 的因果关系.
- 为了区分肥胖对基于肌素和基于囊素的eGFR的影响.

- 评估的体重指数 (BMI) 和腰围 (WC) 作为基于肌素和囊素C的EGFR的暴露变量.
主要成果:
- 肥胖度 (BMI,WC) 显示与基于cystatin C的eGFR有负相关性.
- 在肥胖度和基于肌素的eGFR之间观察到积极的关联.

Glomerular Filtration Rate and its Regulation
1.9K
The Glomerular Filtration Rate (GFR) is a measure of kidney function, reflecting the volume of filtrate formed per minute in the kidneys. On average, GFR is approximately 125 mL/min in males and 105 mL/min in females. Maintaining a relatively constant GFR is essential for the kidneys to effectively regulate body fluid homeostasis and maintain extracellular stability.
GFR regulation involves two primary intrinsic controls: the myogenic and tubuloglomerular feedback mechanisms.
The myogenic...

Obesity
347
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Nature and Nurture
20.3K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Factors Affecting Renal Clearance: Renal Impairment
36
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
