Characteristics of Patients with Decreased Cognitive Function Undergoing Treatment for Acute Exacerbation of Chronic Heart Failure—Basic Survey for Standardization of Nursing to Prevent Discontinuation of Treatment

The purpose of this study is to clarify the characteristics of patients with decreased cognitive function undergoing treatment for acute exacerbation phase of chronic heart failure as a basic survey with a view to the standardization of nursing to prevent discontinuation of treatment of patients with declining cognitive function in the acute exacerbation phase of chronic heart failure. As the first stage of the research, using the interview guide created based on the background of discontinuation of treatment and symptomatic monitoring from 33 target literature sources, seven certified chronic heart failure nurses and 15 certified dementia nurses were given semi-structured interviews. Data obtained from the interviews was analyzed by qualitative induction. As a result, we obtained opinions/views on 8 situations namely, “cognitive function at hospitalization”, “characteristics at hospitalization, “characteristics when receiving examinations, procedures or treatment”, “characteristics of course of treatment”, “characteristics related to difficulties in grasping the symptoms of chronic heart failure and indices of deterioration”, “characteristics when using diuretics”, “characteristics concerning compliance with dietary restrictions” and “support required for discharge from hospital” concerning patients with declining cognitive function. In the future, it is necessary to prepare nursing protocols incorporating these contents for standardization of nursing.

Development of Nursing Protocol for Preventing Interruptions during Clinical Examinations and Treatments in the Early Days of Hospitalization for Acute Exacerbation of Chronic Heart Failure in Patients with Impaired Cognitive Function

The purpose of this study is to prepare a nursing protocol for preventing interruptions during clinical examinations and treatments performed in the early days of hospitalization for acute exacerbation of chronic heart failure in patients with impaired cognitive function. For the first stage of the research, we prepared a draft of the nursing protocol based on a basic survey. For the second stage, semi-structured interviews were conducted with 5 nurses specialized in chronic heart failure and 11 nurses in dementia care to ensure content validity of the draft protocol. For the third stage, we examined the possibility of clinical application of the revised version of the protocol draft prepared in the second stage of the study. For assessment items, significant points of nursing care, and specific nursing care practice in this revised version, 73 subjects (84.9%) considered effective for patients, in terms of prevention of interruptions during clinical examinations and treatments in the early days of hospitalization. All items and contents were considered useful by more than 60% of the nurses. Considering that the nurses working in the clinical setting reported 84.9% of usefulness, we concluded that this nursing protocol remained valid at a certain level. We consider that this nursing protocol will be useful especially for newly graduated/employed nurses as a procedure manual which can reduce their anxiety or stress caused by lack of knowledge or experiences.

Development of Nursing Protocol for Preventing Discontinuation of Treatments by Methods Other than Physical Restraint during Acute Exacerbation of Chronic Heart Failure in Patients with Impaired Cognitive Function

The purpose of this study is to prepare a nursing protocol for preventing discontinuation of treatments using a method other than physical restraint during acute exacerbation of chronic heart failure in patients with impaired cognitive function. For the first stage of the study, we prepared a draft of the nursing protocol based on a basic survey. For the second stage, semi-structured interviews were conducted with 5 nurses specialized in chronic heart failure and 10 nurses in dementia case to ensure content validity of the draft protocol. For the third stage, we examined the possibility of clinical application of the revised version of the protocol draft prepared in the second stage of the study. For assessment items, significant points of nursing care, and specific nursing care practice in this revised version, 154 subjects (93.9%) considered effective for patients, in terms of prevention of treatment discontinuation using a method other than physical restraint. All items and contents were considered useful by more than 60% of the nurses. Considering that the nurses working in the clinical setting reported 93.9% of usefulness, we concluded that this nursing protocol remained valid at a certain level. We also received a comment from the certified nurses that we should include the basic contents for newly graduated nurses. We consider that this nursing protocol will be also useful for newly graduated nurses to acquire knowledge. It helped to standardize nursing care in order to predict potential risks for patients with impaired cognitive function.

Development of a Nursing Protocol for Hospitalized Patients with Reduced Cognitive Function in the Process of Recovery from Acute Exacerbation of Chronic Heart Failure

The purpose of this study is to develop a nursing protocol aiming at early recovery of hospitalized patients with reduced cognitive functions in the process of recovery from acute exacerbation of chronic heart failure. At the first stage of the research, a draft nursing protocol was prepared based on a basic survey. At the second stage of research, a semi-structured interview was conducted for 4 nurses certified for chronic heart failure nursing and 11 nurses certified for dementia nursing so as to ensure content validity of the draft nursing protocol. At the third stage of the study, the possibility of clinical application of the nursing protocol revision plan proposed at the second stage of the study was examined. The nursing protocol revision plan was effective for 118 nurses (90.1%) who carried out the protocol for the target patient on assessment items, essential points of nursing care and specific nursing care. There were no items or contents for which confirmation of usefulness was less than 60%. Since 90.1% of the usefulness was confirmed by nurses working in the actual clinical setting, the authors believe that this nursing protocol was secured to a certain level. The nursing protocol developed in this study has been requested by nurses at clinical sites in the past. It is very meaningful in improving nursing for the early recovery of hospitalized patients with reduced cognitive function in the process of recovery from acute exacerbation of chronic heart failure.

Effect of ivabradine in the treatment of acute exacerbation of chronic obstructive pulmonary disease with heart failure

Objective: To observe the effectiveness and safety of ivabradine in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and heart failure. Methods:Patients who were admitted to hospital with AECOPD during the period from August 2017 to July 2018. Then those both had heart failure with reduced ejection fraction(HFrEF) and a resting heart rate>70 beats/min were enrolled. A total of 86 cases were screened and completed, which were randomly divided into two groups for treatment. The control group(41 cases) received standard treatments, such as oxygen, anti-infection, anti-spasmodic, hormone, diuretic, ACEI/ARB, recombinant human brain natriuretic peptide (rhBNP), etc. The bisoprolol was given 2.5~5 mg orally once a day to control heart rate, and the test group(45 cases) was further treated with ivabradine 2.5~5 mg orally twice a day on the basis of the control group. The average heart rate, cardiac function, lung function, and 6-minute walking test were compared between the two groups. Results: After treatment, the average heart rate of the test group was lower than the control group, and the heart rate control rate(<70 beats/min%) of the test group was superior to the control group. The level of N-terminal B-type natriuretic peptide(NT-proBNP) in test group was significantly lower than that in control group. The distance of the 6-minute walking test in e test group was significantly longer than that in control group. Conclusion: Ivabradine combined with bisoprolol could help patients with AECOPD and heart failure to further reduce the heart rates, improve heart function and exercise tolerance. Moreover, the therapeutic safety was acceptable during the short term.

Risk factors for progression to acute-on-chronic liver failure during severe acute exacerbation of chronic hepatitis B virus infection

BACKGROUND Acute exacerbation in patients with chronic hepatitis B virus(HBV) infection results in different severities of liver injury. The risk factors related to progression to hepatic decompensation(HD) and acute-on-chronic liver failure(ACLF) in patients with severe acute exacerbation(SAE) of chronic HBV infection remain unknown.AIM To identify risk factors related to progression to HD and ACLF in compensated patients with SAE of chronic HBV infection.METHODS The baseline characteristics of 164 patients with SAE of chronic HBV infection were retrospectively reviewed. Independent risk factors associated with progression to HD and ACLF were identified. The predictive values of our previously established prediction model in patients with acute exacerbation(AE model) and the model for end-stage liver disease(MELD) score in predicting the development of ACLF were evaluated.RESULTS Among 164 patients with SAE, 83(50.6%) had compensated liver cirrhosis(LC),43 had progression to HD without ACLF, and 29 had progression to ACLF within 28 d after admission. Independent risk factors associated with progression to HD were LC and low alanine aminotransferase. Independent risk factors for progression to ACLF were LC, high MELD score, high aspartate aminotransferase(AST) levels, and low prothrombin activity(PTA). The area under the receiver operating characteristic of the AE model [0.844, 95%confidence interval(CI): 0.779-0.896] was significantly higher than that of MELD score(0.690, 95%CI: 0.613-0.760, P < 0.05) in predicting the development of ACLF.CONCLUSION In patients with SAE of chronic HBV infection, LC is an independent risk factor for progression to both HD and ACLF. High MELD score, high AST, and low PTA are associated with progression to ACLF. The AE model is a better predictor of ACLF development in patients with SAE than MELD score.

Prognostic impact of atrial fibrillation on clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease

Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.

The Lebanese Society of Cardiology Consensus Statement on the Use of Natriuretic Peptides for the Management of Heart Failure

Plasma concentration of Natriuretic Peptide (NP) is a valuable diagnostic tool for heart failure (HF). It can help rule out or confirm a diagnosis of HF based on symptoms, but its use is not clearly defined. NPs should be used in conjunction with physical examination and other diagnostic tests. However, it is important to note that several conditions besides the diagnosis of HF may cause NPs levels to be elevated. Additionally, there are situations when NP concentrations may be below diagnostic thresholds in [1]. This consensus statement aims to provide a straightforward diagnostic flowchart for clinicians in both the emergency department and outpatient settings to aid in diagnosing both acute and chronic HF. The diagnosis of acute HF can be ruled out with a BNP level of 100 pg/mL or NTproBNP level of 300 pg/mL, regardless of the patient’s age. To identify HF, a 3-level cut-off point based on the patient’s age is recommended. Chronic heart failure can be ruled out with a BNP level of 35 pg/mL or NTproBNP level of 125 pg/mL, regardless of thepatient’s age [1].

Application of fiberoptic bronchscopy in patients with acute exacerbations of chronic obstructive pulmonary disease during sequential weaning of invasive-noninvasive mechanical ventilation

BACKGROUND:Early withdrawal of invasive mechanical ventilation(IMV) followed by noninvasive MV(NIMV) is a new strategy for changing modes of treatment in patients with acute exacerbations of chronic obstructive pulmonary disease(AECOPD) with acute respiratory failure(ARF).Using pulmonary infection control window(PIC window) as the switch point for transferring from invasive to noninvasive MV,the time for early extubation can be more accurately judged,and therapy efficacy can be improved.This study aimed to prospectively investigate the clinical effectiveness of fiberoptic bronchscopy(FOB) in patients with AECOPD during sequential weaning of invasive-noninvasive MV.METHODS:Since July 2006 to January 2011,106 AECOPD patients with ARF were treated with comprehensive medication and IMV after hospitalization.Patients were randomly divided into two groups according to whether fiberoptic bronchoscope is used(group A,n=54) or not(group B,n=52) during sequential weaning from invasive to noninvasive MV.In group A,for sputum suction and bronchoalveolar lavage(BAL),a fiberoptic bronchoscope was put into the airway from the outside of an endotracheal tube,which was accompanied with uninterrupted use of a ventilator.After achieving PIC window,patients of both groups changed to NIMV mode,and weaned from ventilation.The following listed indices were used to compare between the groups after treatment:1) the occurrence time of PIC,the duration of MV,the length of ICU stay,the success rate of weaning from MV for the first time,the rate of reventilatJon and the occurrence rate of ventilator-associated pneumonia(VAP);2) the convenience and safety of FOB manipulation.The results were compared using Student's f test and the Chi-square test.RESULTS:The occurrence time of PIC was(5.01 ±1.49) d,(5.87±1.87) d in groups A and B,respectively(P<0.05);the duration of MV was(6.98±1.84) d,(8.69±2.41) d in groups A and B,respectively(P<0.01);the length of ICU stay was(9.25±1.84) d,(11.10±2.63) d in groups A and B,respectively(P<0.01);the success rate of weaning for the first time was 96.30%,76.92%in groups A and B,respectively(P<0.01);the rate of reventilation was 5.56%,19.23%in groups A and B,respectively(P<0.05);and the occurrence rate of VAP was 3.70%,23.07%in groups A and B,respectively(P<0.01).Moreover,it was easy and safe to manipulate FOB,and no side effect was observed.CONCLUSIONS:The application of FOB in patients with AECOPD during sequential weaning of invasive-noninvasive MV is effective in ICU.It can decrease the duration of MV and the length of ICU stay,increase the success rate from weaning MV for the first time,reduce the rate of reventilation and the occurrence rate of VAP.In addition,such a method is convenient and safe in patients of this kind.

Effects of low molecular weight heparin on the function of blood coagulation and serum levels of TNF-α, CK-MB, CRP of patients with acute exacerbations of chronic obstructive pulmonary diseases and respiratory failur

Objective:To study the effects of low molecular weight heparin on the function of blood coagulation and serum levels of tumor necrosis factor-α(TNF-α), creatine kinase isoenzyme (CK-MB), C-reactive protein (CRP) of patients with acute exacerbations of chronic obstructive pulmonary diseases and respiratory failure.Methods:A total of 80 patients with acute exacerbations of chronic obstructive pulmonary diseases and respiratory failure in our hospital from June 2014 to October 2016 were enrolled in this study. The subjects were divided into the control group (n=40) and the treatment group (n=40) randomly. The control group were treated with conventional treatment, the treatment group were treated with the conventional treatment combined with low molecular weight heparin. The two groups were treated for 7 d. The D-dimer (D-D), fibrinogen (FBG), pro thrombin time (PT), thrombin time (TT), TNF-α, CK-MB and CRP of the two groups before and after treatment were compared.Results:There were no significantly differences of the blood levels of D-D, FBG, PT and TT of the two groups before treatment. After treatment, the blood levels of D-D and FBG of the two groups were significantly lower than before treatment, and that of the treatment group were significantly lower than the control group, the PT and TT of the two groups were significantly higher than before treatment, and that of the treatment group were significantly higher than the control group. There were no significantly differences of the serum levels of the TNF-α, CK-MB and CRP of the two groups before treatment. After treatment, the serum levels of the TNF-α, CK-MB and CRP of the two groups were significantly lower than before treatment, and that of the treatment group were significantly lower than the control group.Conclusion:Low molecular weight heparin can significantly reduce the inflammatory factors of the patients with acute exacerbations of chronic obstructive pulmonary diseases and respiratory failure, can alleviath the patients conditions and reduce the myocardial damage.

Score model for predicting acute-on-chronic liver failure risk in chronic hepatitis B

AIM: To establish a clinical scoring model to predict risk of acute-on-chronic liver failure(ACLF) in chronic hepatitis B(CHB) patients.METHODS: This was a retrospective study of 1457 patients hospitalized for CHB between October 2008 and October 2013 at the Beijing Ditan Hospital, Capital Medical University, China. The patients were divided into two groups: severe acute exacerbation(SAE) group(n = 382) and non-SAE group(n = 1075). The SAE group was classified as the high-risk group based on the higher incidence of ACLF in this group than in the non-SAE group(13.6% vs 0.4%). Two-thirds of SAE patients were randomly assigned to risk-model derivation and the other one-third to model validation. Univariate risk factors associated with the outcome were entered into a multivariate logistic regression model for screening independent risk factors. Each variable was assigned an integer value based on the regression coefficients, and the final score was the sum of these values in the derivation set. Model discrimination and calibration were assessed using area under the receiver operating characteristic curve and the Hosmer-Lemeshow test. RESULTS: The risk prediction scoring model includedthe following four factors: age ≥ 40 years, total bilirubin ≥ 171 μmol/L, prothrombin activity 40%-60%, and hepatitis B virus DNA > 107 copies/m L. The sum risk score ranged from 0 to 7; 0-3 identified patients with lower risk of ACLF, whereas 4-7 identified patients with higher risk. The Kaplan-Meier analysis showed the cumulative risk for ACLF and ACLF-related death in the two risk groups(0-3 and 4-7 scores) of the primary cohort over 56 d, and log-rank test revealed a significant difference(2.0% vs 33.8% and 0.8% vs 9.4%, respectively; both P < 0.0001). In the derivation and validation data sets, the model had good discrimination(C index = 0.857, 95% confidence interval: 0.800-0.913 and C index = 0.889, 95% confidence interval: 0.820-0.957, respectively) and calibration demonstrated by the Hosmer-Lemeshow test(χ2 = 4.516, P = 0.808 and χ2 = 1.959, P = 0.923, respectively).CONCLUSION: Using the scoring model, clinicians can easily identify patients(total score ≥ 4) at high risk of ACLF and ACLF-related death early during SAE.

Performance measures for management of chronic heart failure patients with acute coronary syndrome in China： results from the Bridging the Gap on Coronary Heart Disease Secondary Prevention in China （BRIG） Project

Background Chronic heart failure （CHF） is a severe clinical syndrome associated with high morbidity and mortality, and with high health care expenditures. No nationwide data are currently available regarding the quality of clinical management of CHF patients in China. The aim of this study was to assess the quality of care of CHF inpatients in China. Methods The American College of Cardiology/American Heart Association Clinical Performance Measures for Adults with Chronic Heart Failure （Inpatient Measurement Set） with slight modifications was used to measure the performance status in 612 CHF patients with acute coronary syndrome （ACS） from 65 hospitals across all regions of China. Results The implementation rates of guideline recommended strategies for CHF management were low. Only 57.5% of the CHF patients received complete discharge instructions, 53.6% of the patients received evaluation of left ventricular systolic function, 62.8% received an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker at discharge, and 52.7% received a p-blocker at discharge, 56.3% of the smokers received smoking cessation counseling. The rate of warfarin utilization was only 9.7% in CHF patients with atrial fibrillation. Most patients （81.4%） did not receive all the first four treatments. There were marked differences in the quality of CHF management among patients with different characteristics. Conclusions Performance measures provide a standardized method of assessing quality of care, and can thus highlight problems in disease management in clinical practice.

目的探讨血清髓样分化因子88(MyD88)、白细胞介素-33(IL-33)、乳酸清除率(LCR)水平在慢性阻塞性肺疾病急性加重期(AECOPD)合并呼吸衰竭患者中的表达及与预后的相关性。方法本研究为回顾性队列研究。纳入2022年1月至2023年12月神木市医院呼吸与危重症医学科收治的AECOPD合并呼吸衰竭患者120例,根据入院治疗28 d后的预后情况分为预后良好组(生存)84例和预后不良组(死亡)36例。入院时收集患者的基本资料,包括年龄、性别、吸烟史、COPD病程等。患者入院后未治疗前测量急性生理学及慢性健康状况评分系统(APACHEⅡ)评分确定是否为急性加重期,同时测量入院后未治疗前的血小板计数(PLT)、中性粒细胞计数、血肌酐(Scr)、谷草转氨酶(GOT)、谷丙转氨酶(GCT)、MyD88、IL-33水平,测量入院后未治疗前及经过治疗、间隔24 h的乳酸水平。采用logistic回归分析探讨影响预后的独立因素,Spearman相关性分析用于评估血清生物标志物与患者预后之间的相关性。采用χ^(2)检验、t检验。结果预后良好组中男50例,女34例,年龄(70.68±3.36)岁,COPD病程(18.74±3.65)年;预后不良组中男21例,女15例,年龄(70.41±3.27)岁,COPD病程(18.59±3.78)年。多因素logistic回归分析表明,APACHEⅡ评分、中性粒细胞计数、MyD88、IL-33、LCR均是AECOPD合并呼吸衰竭患者预后不良的影响因素(均P<0.05)。Spearman相关性分析表明,血清MyD88、IL-33与不良预后呈正相关(r=0.641、0.640,均P<0.05),LCR与不良预后呈负相关(r=-0.695,P<0.05)。受试者操作特征曲线(ROC)表明,联合血清MyD88、IL-33、LCR预测AECOPD合并呼吸衰竭患者预后不良的曲线下面积为0.987(95%CI 0.972~1.000)、灵敏度为94.4%、特异度为97.6%、约登指数为0.920,诊断效能最高。结论在AECOPD合并呼吸衰竭预后不良患者中,血清MyD88、IL-33表达上调,LCR水平降低,三者联合应用具有良好的诊断效能。

噻托溴铵治疗慢性阻塞性肺疾病急性加重期合并急性呼吸衰竭的临床研究

目的探讨慢性阻塞性肺疾病急性加重期(acute exacerbation of chronic obstructive pulmonary disease,AECOPD)合并急性呼吸衰竭患者应用噻托溴铵治疗的临床疗效。方法选取2019年3月至2022年3月湖州市第一人民医院收治的106例AECOPD合并急性呼吸衰竭患者,根据随机数字表法将其分为观察组和对照组,每组各53例。两组患者均给予常规治疗,对照组予以无创双相气道正压通气治疗,观察组在对照组的基础上加用噻托溴铵治疗。两组患者均治疗14d。比较两组患者的临床疗效、肺功能、血气指标、炎症因子及不良反应发生情况。结果观察组患者的治疗总有效率显著高于对照组(94.34%vs.79.25%,χ2=5.267,P=0.023)。治疗后,观察组患者的第1秒用力呼气容积、第1秒用力呼气容积/用力肺活量、呼气流量峰值、pH、经皮动脉血氧饱和度、动脉血氧分压均显著高于对照组(P<0.05),动脉血二氧化碳分压、白细胞介素-6、白细胞介素-8、肿瘤坏死因子-α及超敏C反应蛋白均显著低于对照组(P<0.05)。两组患者的用药不良反应及呼吸机不良反应发生率比较差异均无统计学意义(P>0.05)。结论噻托溴铵治疗AECOPD合并急性呼吸衰竭可显著提升疗效,改善患者的肺功能及动脉血气,但需要注意口干等不良反应的及时处理。

精细化容量管理对慢性心力衰竭急性加重患者的影响

目的:分析精细化容量管理在慢性心力衰竭急性加重患者出院前后护理中的应用效果,以期进一步提高慢性心力衰竭急性加重患者的临床护理水平。方法:采用便利抽样法选择2022年9月至2023年3月在北京市某三级甲等医院心内科住院的60例慢性心力衰竭急性加重患者,随机分为对照组和实验组。对照组采用药物常规治疗加常规心内科护理,实验组在对照组的基础上进行精细化容量管理干预,评价精细化容量管理对住院天数、氨基末端脑钠肽前体、明尼苏达心力衰竭生活质量问卷、出院3个月心力衰竭再住院情况的影响。结果:实验组的住院天数明显短于对照组(P=0.024),且住院期间实验组的氨基末端脑钠肽前体下降水平优于对照组(P=0.025),干预2周后,实验组的明尼苏达心力衰竭生活质量问卷评分明显低于对照组(P=0.048),但实验组与对照组的出院3个月再住院情况比较,差异无统计学意义(P=0.731)。结论:精细化容量管理方法可行、有效,在不增加治疗成本的基础上,可以明显缩短慢性心力衰竭急性加重患者的住院时间,提高生活质量。
