Factors affecting compliance to intravitreal anti-vascular endothelial growth factor therapy in Indian patients with retinal vein occlusion,age-related macular degeneration,and diabetic macular edema

Purpose:To evaluate the rate of compliance and the reasons for loss to follow-up in Indian patients with diabetic macular edema (DME), age-related macular degeneration (AMD), and retinal vein occlusion (RVO) being treated with anti-vascular endothelial growth factor (VEGF) therapy.Methods:This was a retrospective single-center study. Patients with DME, AMD, or RVO were eligible if they initiated anti-VEGF therapy between January 2013 and December 2017. Patients'' data were obtained from hospital electronic records, including the number of injections received, visits, details of follow-up, missed appointments, and reasons for loss to follow-up (>365 days).Results:A total of 648 patients were eligible for the study, of which 334 (51.54%) patients were lost to follow-up. Overall, 343 (64.96%) were males and the overall mean (SD) age was 66.40 (7.44) years. A total of 376 (58.0%) patients had a history of diabetes and 364 (56.2%) patients had a history of hypertension. Further, 127 (38.0), 112 (33.5), and 95 (28.4) had DME, AMD, and RVO, respectively and were lost to follow-up. The most commonly reported reason for loss to follow-up was “non-affordability” (n = 120; 41.1%) followed by “no improvement in vision” (n = 83; 28.4%). “No improvement in vision” (42.2%) and “non-affordability” (37.5%) were higher among patients with DME. No association was found in gender- and treatment-wise distribution of reasons for loss to follow-up.Conclusion:The results showed that around half of the patients with DME, AMD, and RVO were lost to follow-up to intravitreal anti-VEGF therapy, and the most common factors were “non-affordability” and “no improvement in vision.”     

新型冠状病毒肺炎出院患者生活质量及影响因素研究

目的:了解新型冠状病毒肺炎(COVID-19)患者出院后的生活质量及其影响因素,为优化早期干预方案,预防社区生活受限,制定相应社区康复措施提供依据。方法:选择2020年3—4月在武汉华润武钢总医院治愈出院的COVID-19患者57例,于2020年4—5月通过"问卷星"平台采用简明健康状况调查量表(SF-12V2)调查患者的生活质量;采用焦虑自评量表(SAS)调查患者的焦虑状态;采用抑郁自评量表(SDS)调查患者的抑郁状态;采用呼吸困难指数量表(mMRC)调查患者的呼吸困难程度。比较不同特征COVID-19患者生活质量的差异;分析患者生活质量与焦虑、抑郁和呼吸困难程度的相关性及其相关的影响因素。结果:共发放57份调查问卷,剔除重复及无效问卷3份,获得有效问卷54份,问卷有效率达94.74%。(1)COVID-19出院后患者生活质量情况:生理总评分和心理总评分分别为(37.02±12.32)分、(38.46±14.42)分;呼吸困难等级0~3级的分别为3例(5.56%)、45例(83.33%)、5例(9.26%)、1例(1.85%);有19例(35.19%)存在焦虑情绪(SAS≥50分)和抑郁情绪(SDS≥53分)。(2)不同特征COVID-19患者生活质量比较:不同疾病分型的患者在生理总评分方面差异有统计学意义(P<0.05)。(3)生活质量与焦虑、抑郁和呼吸困难程度的相关性分析:Pearson相关分析结果显示,SF-12V2生理总评分与焦虑程度(r=-0.34,P=0.011)和呼吸困难程度(r=-0.39,P=0.003)之间存在负相关性,SF-12V2心理总评分与焦虑程度(r=-0.46,P=0.001)和抑郁程度(r=-0.40,P=0.002)之间存在负相关性。(4)COVID-19患者生活质量的影响因素分析:多元线性回归分析显示,性别(β=8.27)、抑郁程度(β=-0.34)和疾病分型(β=-11.68)是患者SF-12V2生理总评分的重要决定因素(P<0.05);焦虑程度(β=-0.62)是患者SF-12V2心理总评分的重要决定因素(P<0.05)。结论:COVID-19出院患者存在呼吸困难、焦虑抑郁情绪和生活质量下降的问题;性别、疾病分型、抑郁程度和焦虑程度是COVID-19患者生活质量下降的重要因素。COVID-19患者(特别是女性患者和重型患者)出院后要尽早进行抑郁症和焦虑症的筛查和干预,减少患者负性情绪,鼓励患者适当参与康复训练,提高呼吸功能,从而促进生活质量提高。     

Niven and Scott (2003): Sixteen years of hindsight

This paper revisits a 2003 publication in Nursing Philosophy: The need for accurate perception and informed judgement in determining the appropriate use of the nursing resource: hearing the patient's voice. The author suggests that the basic ideas and focus of this 16‐year‐old paper are still topical and relevant in considerations of nursing care. However, it is also suggested that greater attention to the importance of the nurse–patient relationship in considerations of resource allocation, and potential rationing of nursing care, would have strengthened the original paper.     

基于“通肾络、益脾肾”治法研究足细胞凋亡及自噬

[目的]基于中医"通肾络、益脾肾"治法,探讨通络益肾方对体外高糖培养的小鼠肾小球足细胞自噬和凋亡蛋白SIRT1、BNIP3、P62、Bax表达的调控影响。[方法]成熟无特定病原体(SPF)级SD雄性大鼠40只,随机分为正常组、中药高、中、低剂量组各10只。按照人与大鼠体表面积折算方法计算出大鼠所需中药灌胃浓度:高剂量浓度4.76 g/mL、中剂量浓度2.38 g/mL、低剂量浓度1.19 g/m L,灌胃10 d取含药血清备用。足细胞分6组,正常组5.6 mmol/L葡萄糖+10%正常大鼠血清、高糖组30mmol/L葡萄糖+10%正常大鼠血清、通络益肾方含药血清高、中、低干预组30 mmol/L葡萄糖+10%高、中、低剂量大鼠血清、高渗组甘露醇24.5 mmol/L+10%正常大鼠血清。细胞培养48 h后收集,Hoechst33342荧光染色,观察各组足细胞凋亡状况及形态变化;流式细胞仪检测足细胞凋亡率;Western Blot检测细胞内自噬标志蛋白SIRT1、P62及促凋亡蛋白BNIP3、Bax表达水平。[结果]流式细胞仪检测结果显示通络益肾方中、低剂量组可降低高糖诱导的足细胞凋亡率(P0.01或P0.05),高剂量组不能改善凋亡情况(P0.05);Hoechst33342荧光染色观察结果也证实通络益肾方中、低剂量组可降低高糖诱导的足细胞凋亡率;蛋白印迹结果显示,与高糖组相比,通络益肾方中、低剂量组自噬标志蛋白SIRT1表达升高,自噬标志蛋白P62及促凋亡蛋白BNIP3、Bax蛋白表达下降(P0.05或P0.01),高剂量组SIRT1、BNIP3、P62、Bax蛋白表达未见明显改变(P0.05)。[结论]中剂量、低剂量通络益肾方能够启动细胞自噬减少高糖刺激下体外培养足细胞凋亡,降低细胞凋亡率及凋亡蛋白的表达。
