Effects of Exercise Training on Restless Legs Syndrome, Depression, Sleep Quality, and Fatigue Among Hemodialysis Patients: A Systematic Review and Meta-analysis.

CONTEXT: Hemodialysis (HD) patients experience a heavy symptom burden that leads to a decreased quality of life. Pharmacological treatment is effective but costly and has adverse effects. Exercise is a promising approach for symptom management, but the effect of exercise on restless legs syndrome (RLS), depression, sleep quality, and fatigue in HD patients is still uncertain. OBJECTIVES: This meta-analysis was conducted to identify whether exercise training is beneficial in the treatment of the symptoms of RLS, depression, poor sleep quality, and fatigue in patients receiving HD. METHODS: A systematic search of PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Cochrane Central Register of Controlled Trials, and Web of Science was conducted to identify randomized controlled trials (RCTs) comparing exercise training with routine care on RLS, depression, sleep quality, and fatigue among HD patients. Quality assessment was conducted using the Cochrane risk of bias tool, and RevMan 5.3 was used to analyze the data. RESULTS: Fifteen RCTs that met our inclusion criteria were included. The pooled effect size showed that exercise training was effective on RLS (P < 0.001), depression (P < 0.001), and fatigue (P < 0.001). However, effect size combinations for sleep quality were not performed owing to the sensitivity analysis results. CONCLUSION: Exercise training may help HD patients to reduce the severity of RLS, depression, and fatigue. More high-quality RCTs with larger samples and comparative RCTs focused on different exercise regimens are needed.

[Effects of Nurse-Led Team Management on Type 2 Diabetes Patients in the Community].

BACKGROUND: Managing increasing numbers of diabetic patients is placing increasing pressure on healthcare providers, especially general practitioners, who usually serve in multiple roles. This situation has caused generally poor results in terms of diabetes management. However, community nurses in some countries have successfully and effectively controlled chronic diseases among their patients. Therefore, the effects of nurse-led management is worth further exploration in order to better understand and promote this mode of care. PURPOSE: To explore the effects of community-nurse-led team management on diabetes patients. METHODS: An experimental research design was adopted. Patients with type 2 diabetes were recruited from two community health centers (the first for the intervention group, the second for the control group) in Wuhou District, Chengdu City, China. The intervention group received nurse-led team management care for 2 years, while the control group received standard care. The evaluations were conducted before the intervention and at 6, 12, and 24 months into the intervention. Outcomes included glycosylated hemoglobin (HbA1c) level, body mass index, waist circumference, visual acuity, ankle brachial index, kidney function index, urinary protein level, and electrocardiogram. RESULTS: The 179 participants included 88 in the intervention group and 91 in the control group. After the intervention, HbA1c level, ankle brachial index, and waist circumference were all significantly better in the intervention group than in the control group (F = 28.894, p < .01; F = 4.065, p < .01; F = 5.540, p < .01). The other outcome variables remained statistically similar between both groups throughout the study period. CONCLUSIONS: Community nurse-led team management is an effective mode of care in terms of controlling blood glucose control and preventing diabetes-related complications.

The Efficacy of a Nurse-Led Disease Management Program in Improving the Quality of Life for Patients with Chronic Kidney Disease: A Meta-Analysis.

BACKGROUND: The impacts of nurse-led disease management programs on the quality of life for patients with chronic kidney disease have not been extensively studied. Furthermore, results of the existing related studies are inconsistent. The focus of the proposed meta-analysis is to evaluate the efficacy of nurse-led disease management programs in improving the quality of life for patients with chronic kidney disease. METHODS: Literature survey was performed to identify the eligible studies from PubMed, Current Nursing and Allied Health Literature, and Cochrane Central Register of Controlled Trials with predefined terms. The outcome measured was quality of life. This meta-analysis was conducted in line with recommendations from the preferred reporting items for systematic reviews and meta-analyses. RESULTS: Eight studies comprising a total of 1520 patients were included in this meta-analysis, with 766 patients assigned to the nurse-led disease management program. Nurse-led disease management improved the quality of life in terms of symptoms, sleep, staff encouragement, pain, general health perception, energy/fatigue, overall health and mental component summary when evaluated 6 weeks after the beginning of intervention. When evaluated 12 weeks later, the quality of life in terms of symptoms, sleep, staff encouragement, energy/fatigue, and physical component summary was improved. Stratified by the modalities of dialysis, similar results of pooled analyses were observed for patients with peritoneal dialysis or hemodialysis, compared with the overall analyses. The results of sensitivity analyses were the same as the primary analyses. The symmetric funnel plot suggested that the possibility of potential publication bias was relatively low. CONCLUSION: Nurse-led disease management program seems effective to improve some parameters of quality of life for patients with chronic kidney disease. However, the seemingly promising results should be cautiously interpreted and generalized and still need to be confirmed through well-designed large-scale prospective randomized controlled trials.

An establishment of vascular access through superior vena cava for a patient with multiple central venous stenosis or occlusion.

The patency of vascular access is of vital importance to dialysis patients. Access dysfunction is largely caused by vessel stenosis and thrombosis. Nephrologists usually find themselves helpless when all treatments fail and the vascular access seems to have exhausted. Here we report a successful establishment of vascular access through superior vena cava for a critical patient with multiple central venous stenosis or occlusion. To our knowledge, it is the first case ever reported on the successful establishment of vascular access through superior vena cava under such a complicated condition of vascular exhaustion.

Charlson comorbidity index helps predict the risk of mortality for patients with type 2 diabetic nephropathy.

Our intent is to examine the predictive role of Charlson comorbidity index (CCI) on mortality of patients with type 2 diabetic nephropathy (DN). Based on the CCI score, the severity of comorbidity was categorized into three grades: mild, with CCI scores of 1-2; moderate, with CCI scores of 3-4; and severe, with CCI scores ≥5. Factors influencing mortality and differences between groups stratified by CCI were determined by logistical regression analysis and one-way analysis of variance (ANOVA). The impact of CCI on mortality was assessed by the Kaplan-Meier analysis. A total of 533 patients with type 2 DN were enrolled in this study, all of them had comorbidity (CCI score >1), and 44.7% (238/533) died. The mortality increased with CCI scores: 21.0% (50/238) patients with CCI scores of 1-2, 56.7% (135/238) patients with CCI scores of 3-4, and 22.3% (53/238) patients with CCI scores ≥5. Logistical regression analysis showed that CCI scores, hemoglobin, and serum albumin were the potential predictors of mortality (P<0.05). One-way ANOVA analysis showed that DN patients with higher CCI scores had lower levels of hemoglobulin, higher levels of serum creatinine, and higher mortality rates than those with lower CCI scores. The Kaplan-Meier curves showed that survival time decreased when the CCI scores and mortality rates went up. In conclusion, CCI provides a simple, readily applicable, and valid method for classifying comorbidities and predicting the mortality of type 2 DN. An increased awareness of the potential comorbidities in type 2 DN patients may provide insights into this complicated disease and improve the outcomes by identifying and treating patients earlier and more effectively.

Influence of HbA1c on short-term blood pressure variability in type 2 diabetic patients with diabetic nephropathy.

The aim of this study was to understand the characteristics of blood pressure (BP) variability in subjects with diabetic nephropathy (DN), and identify the probable predictors affecting BP variability. Fifty-one chronic kidney disease (CKD)-hypertensive patients without diabetes (NDN group) and sixty type 2 diabetic patients with overt DN (DN group) were enrolled in this study. The values of short-term BP variability were obtained from 24 h ambulatory BP monitoring (ABPM). Variance analysis or nonparametric analysis revealed that 24-h systolic BP variability and nighttime systolic BP variability of the DN group were significantly higher than those of the NDN group [(12.23±3.66) vs. (10.74±3.83) mmHg, P<0.05; (11.23±4.82) vs. (9.48±3.69) mmHg, P<0.05]. Then the patients of the DN group were divided into two groups according to glycated hemoglobin (HbA1c) level: Group A (HbA1c<7%) and Group B (HbA1c≥7%), and the t-test showed that patients in Group B had larger 24-h diastolic, daytime diastolic, and nighttime systolic/diastolic BP variability compared with Group A. In the DN group, partial correlation analysis revealed that HbA1c exhibited a strong association with 24-h diastolic, daytime diastolic, nighttime systolic and diastolic BP variability (P<0.001, P<0.001, P<0.05, and P<0.001, respectively). Taken together, larger short-term BP variability was detected in hypertensive type 2 diabetic patients with overt nephropathy and renal insufficiency. It may imply that the optimal BP variability level could benefit from a better glycaemic control.
