概括
在正常BMI和超重个体中,内脏肥胖 (VO) 与脏结构变化和脏切除术后脏功能补偿减少有关. 这凸显了内脏脂肪组织 (VAT) 评估对手术规划的重要性.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 病理学 病理学 病理学
- 放射学 放射学是一门学科.
背景情况:
- 肥胖是慢性病 (CKD) 的已知危险因素之一.
- 内脏肥胖 (VO),以过多的内脏脂肪组织 (VAT) 为特征,即使在正常体重指数 (BMI) 或超重状态的个体中也可能发生.
- 虽然VO与功能受损有关,但其对形态和补偿能力的具体影响仍然不太清楚.
研究的目的:
- 为了研究VO和球超结构之间的关联.
- 在有VO的个体中分析 podocyte 形态测量 (podometrics).
- 在正常的BMI和超重个体中,评估VO对脏补偿功能的影响.
主要方法:
- 使用计算机断层扫描 (CT) 对52名经过切除术的患者 (BMI <30 kg/m2) 进行了VAT的追溯量化.
- 定义VO为增值税面积≥100厘米2.
- 基于深度学习的分析,对非瘤脏组织的球形状测量和足度测量,以及线性回归来评估脏切除术后估计球过率 (ΔeGFR) 的变化.
主要成果:
- 与没有VO的人相比,有VO的人 (n=35) 显示出显著增加的球体积,较低的细胞密度和细胞核缩.
- 在非切除术后,VO与功能补偿受损有关,这表明 ΔeGFR. 的较大下降.
- 淋巴细胞扩大,细胞密度降低和核缩与 ΔeGFR 减少有显著的相关性.
结论:
- 内脏肥胖与球体和细胞结构的有害变化有关.
- 在正常的BMI和超重个体中,VO损害了脏补偿切除术的能力.
- 增值税的量化可能有助于为接受切除术的患者做出手术前的决策.

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

2.0K
Metabolic reactions in the body produce nonvolatile acids, such as sulfuric acid, which generate an acid load of approximately 1 mEq of H+ per kilogram of body weight daily. Excreting H+ in the urine is essential to balance this acid load.
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.
