Objective To explore the application effect of narrative nursing in elderly patients with pain.Methods From December 2020 to December 2023,84 elderly patients with malignant tumor in the General Hospital of the Southern Theater Command of the People’s Liberation Army of China were randomly divided into control group(n=42)receiving routine intervention and observation group(n=42)receiving narrative nursing.Results The pain digital grading scores of the observation group at 2 weeks,4 weeks,6 weeks and 8 weeks after intervention were(5.02±1.07),(4.26±0.76),(3.58±0.65)and(2.92±0.41),which were lower than the control group(t=2.126,2.419,3.232,2.545,all P<0.05).After 2 months of intervention,the scores of Self-Rating Anxiety Scale,Self-Rating Depression Scale and Pittsburgh Sleep Quality Index in the observation group were(41.27±2.28),(42.47±3.19)and(5.13±1.46),which were lower than the control group(t=11.795,9.669,3.579,P<0.05).The score of general self-efficacy scale was(21.72±4.13),which was higher than the control group(t=5.834,P<0.05).Conclusions Narrative nursing can effectively control the pain of elderly patients with cancer pain,significantly improve negative emotions and sleep status,and is conducive to the improvement of self-efficacy.
目的 探究血清多配体蛋白聚糖-1(SCD-1)与可溶性血管内皮生长因子受体-2(sVEGFR-2)表达水平在老年慢性心力衰竭患者预后评估的判定价值。方法 选取2023年1月—2024年3月珠海市第五人民医院检验科收治的110例老年慢性心力衰竭患者,检测其血清SCD-1和sVEGFR-2水平,对患者进行随访调查,了解其再次由于心力衰竭住院、心源性死亡的情况。运用多因素Logistic回归分析,探究老年慢性心力衰竭患者预后影响因素。结果 Logistic回归分析显示,心功能分级(OR=3.433,95%CI:0.934~6.431)、B型脑钠肽升高(OR=2.462,95%CI:0.861~4.765)、血清SCD-1升高(OR=3.795,95%CI:0.972~6.894)、血清sVEGFR-2升高(OR=3.842,95%CI:0.942~6.912)为影响老年慢性心力衰竭患者预后不良的重要因素(P<0.05);联合血清SCD-1和sVEGFR-2曲线下面积0.962与B型脑肽钠曲线下面积0.844,相较于单一SCD-1曲线下面积0.658、sVEGFR-2曲线下面积0.712明显偏高(P<0.05)。结论 经研究证实,老年慢性心力衰竭患者预后效果不理想,其血清SCD-1和sVEGFR-2监测水平异常升高,和老年慢性心力衰竭预后不佳存在关联性,可视为老年慢性心力衰竭患者判定预后效果的主要标志物。
Objective To investigate the prognostic value of serum syndecan-1(SCD-1)and soluble vascular endothelial growth factor receptor-2(sVEGFR-2)expression levels in elderly patients with chronic heart failure.Methods A total of 110 elderly patients with chronic heart failure admitted to our hospital were selected,with a time interval of January 2023 to March 2024.Serum SCD-1 and sVEGFR-2 levels were detected and follow-up investigations were conducted to understand their re hospitalization and cardiogenic death due to heart failure.Multiple logistic regression analysis was used to explore the prognostic factors affecting elderly patients with chronic heart failure.Results According to logistic retrospective analysis,heart function grading(OR=3.433,95%CI:0.934-6.431),elevated B-type brain natriuretic peptide(OR=2.462,95%CI:0.861-4.765),elevated serum SCD-1(OR=3.795,95%CI:0.972-6.894),and elevated serum sVEGFR-2(OR=3.842,95%CI:0.942-6.912)were important factors affecting the poor prognosis of elderly patients with chronic heart failure,with differences P<0.05.The area under the curve of combined serum SCD-1 and sVEGFR-2 was 0.962,and the area under the curve of B-type brain peptide sodium was 0.844,which was significantly higher than that of a single SCD-1 curve of 0.658 and sVEGFR-2 curve of 0.712,with a difference of P<0.05.Conclusions Research has confirmed that the prognosis of elderly patients with chronic heart failure is not satisfied,and their serum SCD-1 and sVEGFR-2 monitoring levels are abnormally elevated,which is related to the poor prognosis of elderly patients with chronic heart failure.It can be regarded as the main biomarker for defining the prognosis of elderly patients with chronic heart failure.
目的 探讨老年营养风险指数(GNRI)与慢性阻塞性肺疾病者急性加重期患者预后的相关性。方法 选择贵州省六盘水水旷医院2019年1月—2022年1月收治的COPD急性加重期患者,根据GNRI值,分为正常营养组(GNRI>98)和营养不良组(GNRI≤98),应用生存曲线和Cox比例风险回归评估营养状况与死亡率之间的关联。结果 共纳入198例COPD急性加重期患者,正常营养组90例,营养不良组108例,营养不良发生率为54.5%;Kaplan-Meier曲线表明,营养不良组的全因累积死亡率更高(58.3% vs 35.0%,P<0.001)。Cox比例风险回归分析显示在未校正模型中,HR为2.31(1.25~4.28),P<0.001。在完全校正模型中,HR为2.48(1.37~4.51),P=0.005,提示与正常营养状况相比,营养不良与全因死亡风险升高相关。结论 GNRI低是COPD患者急性加重期全因死亡的独立危险因素。
Objective To investigate the correlation between elderly nutritional risk index(GNRI)and prognosis of patients with AECOPD.Methods Patients with AECOPD admitted to our hospital from January 2019 to January 2022 were selected and divided into normal nutrition group(GNRI>98)and malnutrition group(GNRI≤98)according to GNRI value.Survival curve and Cox regression were used to evaluate the association between nutritional status and mortality.Results A total of 198 patients with AECOPD were included in this study.According to GNRI scores,90 patients were in the normal nutrition group and 108 were in the malnutrition group,with malnutrition incidence of 54.5%.The Kaplan-Meier curve showed that the cumulative all-cause mortality was higher in the malnutrition group(58.3% vs 35%,P<0.001).Cox proportional hazard regression analysis showed that HR in the uncorrected model was 2.31(1.25-4.28),P<0.001.In the fully corrected model,HR was 2.4(1.37-4.51)and P=0.005,suggesting that malnutrition was associated with a significantly higher risk of all-cause mortalitycompared with normal nutritional status.Conclusions Low GNRI is an independent risk factor for all-cause death in AECOPD patients.
