Chinese Healthcare Workers' Knowledge, Attitudes, and Practices in Diabetic Kidney Management: A Multi-Centered Cross-Sectional Study.

Background: Given the importance of diabetic kidney disease (DKD) management, this study aims to explore the knowledge, attitudes, and practices in disease management demonstrated by healthcare workers from the nephrology department. Materials and Methods: This study is a multi-centered cross-sectional study, and adopts snowball sampling, with 530 healthcare workers being recruited to complete a questionnaire covering areas such as demographic characteristics, knowledge, attitude, and practices (KAP) of DKD management. This data was analyzed using descriptive statistics and binary logistics analysis. Results: In this study, 530 healthcare workers were studied, including 94 doctors and 436 nurses. The participants were mainly from general tertiary hospitals in 14 provinces. For Chinese nurse, the results indicate that both poor knowledge level (Odds Ratio (OR) =0.63, 95% Confidence Interval (CI): 0.42-0.94) and having experience in further medical training in nephrology (OR=1.92, 95% CI: 1.20-3.08) are associated with the practice levels. For Chinese doctors, having not experience in further medical training in nephrology (OR=0.36, 95% CI: 0.15-0.83) are associated with their practice levels. Conclusion: In summary, Chinese doctors and nurses in this study showed positive attitudes towards DKD management, but their knowledge and practical skills were lacking. This underscores a notable gap in achieving optimal DKD care. Notably, nurses' knowledge influenced their management practices, and additional nephrology training correlated with better engagement. To improve patient care, enhancing nephrology healthcare professional training and addressing knowledge-practice disparities are recommended.

Exploring Symptom Clusters in Chinese Patients with Diabetic Kidney Disease: A Network Analysis.

Purpose: The research on symptom management in patients with diabetic kidney disease (DKD) has shifted from separate symptoms to symptom clusters and networks recently. This study aimed to evaluate the unpleasant symptoms of DKD patients, and to investigate how these symptom clusters could affect patients. Methods: 408 DKD patients were recruited in this cross-sectional study. The symptoms of DKD patients were measured using the modified Dialysis Symptom Index. Network analysis was employed to evaluate the symptom network and the characteristics of individual nodes, while factor analysis was utilized to identify symptom clusters. Results: Blurred vision was the most prevalent symptom among DKD patients. The symptoms identified as the most distressing, severe, and frequent were light headache or dizziness, arteriovenous fistula/catheterization pain, and diarrhea, respectively. Five symptom clusters were obtained from factor analysis, and the most central symptom cluster in the entire symptom network was sexual dysfunction. Conclusion: This study identified five symptom clusters in Chinese DKD patients, with sexual dysfunction emerging as the most central cluster. These findings carry significant clinical implications, underscoring the necessity of assessing symptom clusters and their associations to enhance symptom management in DKD patients. Further research is essential to elucidate the underlying mechanisms of symptoms and to clarify the associations among symptoms in DKD patients across different disease trajectories or treatment modalities.

COVID-19 and outcomes in Chinese peritoneal dialysis patients.

BACKGROUND: Reports on COVID-19 in peritoneal dialysis (PD) patients are scarce in China. This study aimed to describe the characteristics and outcomes of PD patients with COVID-19 after China abandoned the 'zero-COVID' policy. METHODS: This single-centre retrospective study included patients receiving PD who underwent testing for COVID-19 infections between 7 December 2022 and 7 January 2023. Outcomes of interest included factors associated with positive COVID-19 testing result and clinical outcomes including COVID-19-related hospitalisation and severe COVID-19, which were analysed using logistic regression analyses. RESULTS: A total of 349 PD patients (male 53.6%, age 49 ± 13 years old) were included, and 235 patients (67.3%) were infected. There were no significant differences between COVID-19 and non-COVID-19 patients other than higher proportion of vaccinated patients and slow transporters in the patients who tested positive for COVID-19 (44.7% vs. 28.1%, p = 0.003; 8.7% vs. 1.8%, p = 0.03, respectively). Multivariate analysis showed COVID-19 was associated with vaccination (odds ratio (OR): 1.71, 95% confidence interval (CI): 1.02-2.86) and slow transport type (compared with average transport type, OR: 4.52, 95% CI: 1.01-20.21). Among the patients with infection, 38 (16.2%) patients were hospitalised, 18 (7.7%) patients had severe disease and 9 (3.8%) patients died. In multivariate logistic analysis, both age (OR: 1.04, 95% CI: 1.01-1.07; OR: 1.06, 95% CI: 1.02-1.11) and hyponatremia (OR: 5.44, 95% CI: 1.63-18.13; OR: 6.50, 95% CI: 1.77-23.85) were independent risk factors for COVID-19-related hospitalisation and severe disease. CONCLUSIONS: Although vaccinated patients were more likely to have tested positive for COVID-19 infection, they appeared to have less severe infection and less need for hospitalisation. Patients who were older with a history of hyponatremia were more likely to experience adverse outcomes from COVID-19.

The Association between Serum Chemerin and Peritoneal Membrane Transport Function in Patients Undergoing Incident Peritoneal Dialysis: A Prospective Cohort Study.

INTRODUCTION: Some biomarkers in drained dialyzate or peritoneal membrane have been found related to the dialyzate/plasma ratio of creatinine at 4 h (D/P Cr) in patients undergoing peritoneal dialysis (PD). But so far, there is no report on serum markers. Some biomarkers are associated with cardiovascular diseases (CVDs). Chemerin is a multifunctional chemoattractant adipokine which plays important roles in inflammation, adipogenesis, and metabolism. We intended to investigate the role of chemerin in the peritoneal membrane transport function and CVDs in incident PD patients. METHODS: This prospective cohort study was conducted in our PD center. The patients underwent initial standardized peritoneal equilibration test after PD for 4-6 weeks. Level of serum chemerin was determined via enzyme-linked immunosorbent assay. The patients' CVDs were recorded during the follow-up period. RESULTS: 151 eligible patients with a mean age of 46.59 ± 13.52 years were enrolled, and the median duration of PD was 25.0 months. The median concentration of serum chemerin was 29.09 ng/mL. Baseline D/P Cr was positively correlated with serum chemerin (r = 0.244, p = 0.003). The multivariate analyses revealed that serum chemerin (p = 0.002), age (p = 0.041), albumin (p = 0.000), and high-density lipoprotein (p = 0.022) were independent factors of D/P Cr. The serum chemerin level was significantly higher in diabetes mellitus (DM) patients than that of patients without DM (36.45 ng/mL vs. 27.37 ng/mL, p = 0.000), and there was a significant statistical difference in CVDs between the high chemerin group (≥29.09 ng/mL) and low chemerin group (<29.09 ng/mL) (42 vs. 21%, p = 0.009). CONCLUSIONS: Serum chemerin has a positive correlation with baseline D/P Cr in incident PD patients. It may be a biomarker that can predict the baseline transport function of the peritoneal membrane, and serum chemerin may be a risk factor of CVDs for incident PD patients. Multicenter studies with a larger sample size are warranted in the future.

Iron Deficiency is Associated With Platelet Count Elevation in Patients With Dialysis-dependent Chronic Kidney Disease.

OBJECTIVE: Iron deficiency is common in patients with end-stage renal disease (ESRD). Platelet count changes may reflect iron status, but the relationship between platelet count and iron indices is unclear in patients with ESRD. METHODS: We conducted a retrospective study in 1,167 patients with ESRD from 2012 to 2017 in West China Hospital. Baseline data were used to analyze the relationship between the platelet count and iron indices. Patients were followed up for 3 years. RESULTS: Patients with iron deficiency (both absolute and functional) had a higher platelet count than those without iron deficiency (174 ± 61 × 109/L vs. 153 ± 58 × 109/L, P < .001). Receiver operating characteristic analysis showed a weak predictive power of platelet count on absolute iron deficiency (area under curve 0.620; cutoff value > 137 × 109/L, sensitivity 76%, specificity 43%) and functional iron deficiency (area under curve 0.540; cutoff value > 124 × 109/L, sensitivity 77%, specificity 32%). Platelet count was negatively correlated with ferritin (Spearman's rho [ρ] -0.1547, P < .001), transferrin saturation (ρ = -0.1895, P < .001), and serum iron (ρ = -0.1466, P < .001). The abovementioned correlations remained significant in multivariate regression (ß -0.7285, 95% confidence interval [CI] -1.0757 to -0.3814; ß -.00347, 95% CI -0.0520 to -0.0174; ß -0.0097, 95% CI -0.0159 to -0.0035, respectively). In unadjusted and adjusted Cox regression models, neither baseline platelet count nor relative thrombocytosis was associated with 3-year mortality. CONCLUSION: There was a weak but significant platelet count elevation in patients with ESRD and with iron deficiency.

Status and factors related to post-traumatic growth in continuous ambulatory peritoneal dialysis: A multi-centre study.

AIM: To investigate the extent of post-traumatic growth, and the correlation between post-traumatic growth and self-perceived stress, post-traumatic growth and self-perceived burden among CAPD patients. DESIGN: A cross-sectional study. METHODS: This was a multi-centre study including 752 patients from 44 hospitals. Self-perceived stress, self-perceived burden and post-traumatic growth were measured using the post-traumatic growth inventory (PTGI), the Chinese version of the perceived stress questionnaire (CPSQ) and the self-perceived burden scale (SPBS). A multiple stepwise regression analysis was fit with the total PTGI score as the outcome of interest. RESULTS: Patients concurrently experienced post-traumatic growth and stress following peritoneal dialysis. The initiation of patients' education level, employment status and self-perceived stress were all found to relate to growth among Chinese CAPD patients. There was not sufficient evidence to suggest that self-perceived burden was related to experiencing growth.

Reproductive concerns and associated factors among female chronic kidney diseases patients: a Multi-Center Cross-Sectional Study.

AIM: The study aimed to investigate the current status of reproductive concerns and explore the associated factors among young female chronic kidney disease (CKD) patients. DESIGN: A multi-center cross-sectional study was designed. METHODS: The study was conducted in six representative tertiary hospitals across southwest China. A total of 295 female Chronic kidney disease patients between 18-45 years of age completed a 20 min, web-based survey, which included demographics and disease-related information questionnaire, Reproductive Concerns Scale, Generalized Anxiety Disorder 7 (GAD-7) instrument and Patient Health Questionnaire 9 (PHQ-9) instrument. RESULT: The survey total collected 270 valid questionnaires. The mean reproductive concern score was 54.39 ± 10.90 (out of a maximum of 90), with the mean scores for sub-scales ranging from 7.80 ± 1.69 to 10.44 ± 1.85. Multiple regression analysis showed that those with higher reproductive concerns were more likely to have pregnancy intentions, to be in Chronic kidney disease stages 1-3, and to have a higher GAD-7 score. This study offered further evidence of the need for improved education and emotional support surrounding reproductive concerns among young Chinese women with Chronic kidney disease.

Moderating Effects of Forgiveness on Relationship Between Empathy and Health-Related Quality of Life in Hemodialysis Patients: A Structural Equation Modeling Approach.

CONTEXT: Health-related quality of life (QOL) is a recommended clinical tool to assess hemodialysis patients and a primary end point to observe the effectiveness of overall disease management. Empathy is associated with positive outcomes such as pain relief and reduced anxiety and distress. Numerous studies have tested the relationships among empathy, forgiveness, and QOL; however, a mechanism of forgiveness has not been fully explored in hemodialysis patients. OBJECTIVES: To test the relationship among empathy and health-related QOL and confirm the moderating effects of forgiveness on relationship between empathy and health-related QOL among hemodialysis patients. METHODS: In a descriptive cross-sectional study conducted from September to December 2017, 457 hemodialysis patients from five hospitals filled out the Heartland Forgiveness Scale, Interpersonal Reactivity Index-C, Kidney Disease Questionnaire, and general information. The data were analyzed using SPSS, and structural equation modeling was used to address the relationships among empathy, forgiveness, and health-related QOL. RESULTS: Empathy was significantly positively associated with health-related QOL. The proposed model had a good fit to the data. Forgiveness was found to play a partial mediating role between empathy and health-related QOL. CONCLUSION: The results imply that empathy significantly directly and indirectly influences health-related QOL. Empathy among hemodialysis patients should be monitored and effectively managed to improve positive effects on their health-related QOL. Nurses should consider implementing empathy interventions with an emphasis on building forgiveness strategies to help hemodialysis patients improve their health-related QOL.

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.
