概括
与葡萄糖相比,icodextrin溶液在腹腔透析中提供了更好的液体和溶液去除. 一个icodextrin交换可以有效地取代两个葡萄糖交换,提高超过效率和去除.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 生物医学工程 生物医学工程
- 药理学 药理学是指药理学的学科.
背景情况:
- 腹腔透析 (PD) 溶液对于衰竭患者的液体和溶液管理至关重要.
- 基于葡萄糖的溶液是标准的,但可以导致更快的透梯度消散.
- 基于icodextrin的溶液提供较慢的透梯度消散,可能改善超过 (UF).
研究的目的:
- 为了研究在PD中用icodextrin取代基于葡萄糖的交换的疗效.
- 为了在各种PD表下比较icodextrin和葡萄糖溶液之间的液体和溶解物去除.
- 为了评估不同腹膜溶液转移速率 (PSTRs) 对icodextrin的性能的影响.
主要方法:
- 使用三孔模型的数值模拟,其中包含了icodextrin水解.
- 对超过 (UF),吸收的葡萄糖 (AbsGluc),吸收的碳水化合物 (AbsCHO) 和超过效率 (UFE) 的评估.
- 在不同停留时间和PSTR中,对7.5%的冰凝与葡萄糖溶液 (1.36%,2.27%) 的去除 (ReNa),尿素 (ReU) 和肌素 (ReCr) 的评估.
主要成果:
- 将每天三到四次葡萄糖交换中的一个替换为7.5%的冰素长期停留增加了液体和溶液的去除和UF的效率.
- 将两种葡萄糖交换换成一种冰烯交换的结果是可比或更高的水分去除和增加每日去除.
- 随着icodextrin的使用,观察到每日尿素和肌素的去除量略低,无论患者的PSTR如何.
结论:
- 一次7.5%的冰素交换可以有效地取代两次基于葡萄糖的交换.
- 在PSTR组中,icodextrin在水和溶解物去除方面表现出极小的差异,UFE稳定长达16小时.
- 伊科德克斯为PD中增强的流体和溶液管理提供了可行的替代方案,特别是在长期停留的交换中.

Insulin: Dosing Regimen and Adverse Effects
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Glucagon-like Receptor Agonists
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...

Peritoneal Dialysis I: Introduction and Procedure
Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...
Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications
Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...
