Total cholesterol to high-density lipoprotein cholesterol ratio is independently associated with CKD progression

Purpose

Although dyslipidemia can cause kidney damage, whether it independently contributes to the progression of chronic kidney disease (CKD) remains controversial. The research aims to evaluate the predictive value of serum lipids and their ratios in the progression of CKD.

Methods

The retrospective, case–control study included 380 adult subjects with CKD stage 3–4 (G3-4) at baseline. The end point of follow-up was the progression of CKD, defined as a composite of renal function rapid decline [an annual estimated glomerular filtration rate (eGFR) decline?>?5 mL/min/1.73 m²] or the new-onset end-stage renal disease (ESRD) [eGFR?<?15 mL/min/1.73 m²]. Logistic regression analysis was performed to examine the association between CKD progression and lipid parameters. Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive power of lipid parameters in the progression of CKD.

Results

Over a median follow-up of 3.0 years, 96 participants (25.3%) developed CKD progression. In multivariable logistic regression analysis, logarithm-transformed urinary albumin-to-creatinine ratio (log ACR) [odds ratio (OR) 1.834;95% confidence interval (CI) 1.253–2.685; P?=?0.002] and total cholesterol to high-density lipoprotein cholesterol ratio (TC/HDL-C) [OR 1.345; 95% CI 1.079–1.677; P?=?0.008] were independently associated with CKD progression. The ROC curve showed the combined predictor of ACR and TC/HDL-C ratio was acceptable for CKD progression diagnosis (area under the ROC curve [AUC]?=?0.716, sensitivity 50.0%, specificity 84.2%), and the cut-off value was ? 0.98.

Conclusions

The combination of TC/HDL-C ratio and ACR had predictive value in the progression of CKD, and may help identify the high-risk population with CKD.

老年永久性肠造口患者过渡期护理方案的构建及应用

目的 构建老年永久性肠造口患者过渡期护理方案并评价其应用效果。方法 将88例老年肠造口患者按病区分为对照组与观察组各44例。对照组采用术后常规护理,观察组在常规护理基础上构建并实施过渡期护理方案。比较两组干预前、干预完成时及干预后3个月护理依赖水平、肠造口自我照护行为执行意向评分。结果 对照组42例、观察组43例完成本研究。两组护理依赖得分、自我照护行为执行意向得分比较,组间效应、时间效应及交互效应差异有统计学意义（均P＜0.05）。结论 对老年肠造口患者实施过渡期护理方案,能够降低患者护理依赖水平,增强患者自我护理意向,有利于促进患者康复。     

神经外科术中获得性压力性损伤的预防护理专案

目的 降低神经外科术中获得性压力性损伤发生率。 方法 将2019年10～12月的1 378例神经外科择期手术患者作为对照组,采取常规护理措施预防术中获得性压力性损伤。将2020年10～12月的1 551例患者作为观察组,成立护理专案小组,开展多学科协作,实施护理专案改善。 结果 观察组术中获得性压力性损伤发生率为0.90%,对照组为2.18%,两组比较,差异有统计学意义（P＜0.05）;两组术中获得性压力性损伤治愈率比较,差异无统计学意义（P＞0.05）。观察组预防术中获得性压力性损伤关键监测指标落实率较好,除术后规范交接班落实875例（61.40%）外,其他指标均＞88.00%。 结论 多学科协作护理专案能够有效降低术中获得性压力性损伤发生率,提高术中获得性压力性损伤预防和管理质量。     

腹膜透析患者自我调节疲劳与生活质量的纵向研究

目的 探讨腹膜透析患者不同阶段自我调节疲劳及生活质量的动态变化,并分析二者相关性。方法 采用便利抽样法,使用自行设计的患者一般资料调查表、自我调节疲劳量表、肾脏病专用生活质量简表对150例腹膜透析患者在置管后1、3、6、12个月时对其开展追踪调查。结果 患者生活质量处于中等偏低水平且呈逐步下降趋势,自我调节疲劳程度处于中等偏高且呈逐渐上升趋势。置管后1、3、6、12个月患者自我调节疲劳与生活质量呈负相关（均P＜0.05）。结论 腹膜透析患者自我调节疲劳及生活质量呈动态变化,自我调节疲劳水平越低时,其生活质量越高。医护人员应重视患者不同阶段的自我调节疲劳水平,实施个性化的干预指导,降低自我控制资源损耗程度,以提高患者生活质量。

脉冲多普勒超声对胎儿不同妊周脐带及脑循环动态变化的研究

目的，探讨不同妊周胎儿脐血流及脑血流的变化规律。方法，对４２２例妊娠２１～４２周正常产妇，用脉冲多普勒超声测量其胎儿脐带动脉（ＵＡ）、大脑中动脉（ＭＣＡ）之ＲＩ（阻力指数）与ＰＩ（搏动指数）。结果与结论，ＲＩ与ＰＩ的变化高度一致（ｒ＝０．９７８）（ｐ＜０．００１）。ＵＡ两指数在妊娠２１周时最高，此后逐渐下降至足月（Ｐ＜０．００１）。ＭＣＡ两指数从２１周起先缓慢上升，２９周时达高峰，此后迅速下降至足月（ｐ＜０．００１）。ＵＡ的ＲＩ、ＰＩ与ＭＣＡ的ＲＩ、ＰＩ之比值，从妊娠２１周起迅速下降，２９～３４周间维持较低水平，以后缓慢上升，到妊娠足月时仍明显低于妊娠２１周时水平（Ｐ＜０．００１）。
