Daily self-care practices influence exit-site condition in patients having peritoneal dialysis: A multicenter cross-sectional survey.

AIMS: To investigate practice patterns in exit-site care and identify the risk factors for exit-site infection. DESIGN: A quantitative cross-sectional design. METHODS: Data were collected in 12 peritoneal dialysis (PD) centres in 2018. Daily exit-site care practice patterns and exit-site status of patients receiving PD were assessed through interviews and questionnaires. RESULTS/FINDINGS: Most of the 1,204 patients adhered with the protocols about main aspects of exit-site care, such as cleansing agents selection, frequency of cleansing, catheter fixation, and following the catheter protective measures. However, their adherence levels on hand hygiene, mask wearing, observing exit site, examining secretion, and communicating with PD staff were rather low. Eighty-four patients' exit sites were evaluated as problematic exit site (PES). And 186 patients had catheter-related infection (CRI) history. After multivariable logistic regression analysis, diabetes (OR = 1.631), traction bleeding history (OR = 2.697), antibiotic agents use (OR = 2.460), compliance on mask wearing (OR = 0.794), and observing exit site (OR = 0.806) were influencing factors of CRI history. Traction bleeding history (OR = 2.436), CRI history (OR = 10.280), and effective communication (OR = 0.808) with PD staff were influencing factors for PES. CONCLUSIONS: The adherence levels on different aspects of exit-site care were varied in patients having PD. Their self-care behaviours did correlate with the exit-site status. IMPACT: The adherence level of patients' exit-site care practice needs attention of medical staff. Further studies about the optimal procedure in exit-site care were warranted.

Risk factors affecting the sleep quality of patients on dialysis: A single-center cross-sectional study.

Sleep quality is among the common complication in patients on dialysis and serious affect their health and quality of life; however, other associated risk factors are unclear. This study aimed to investigate the risk factors affecting sleep quality in patients on dialysis. Data were collected from 260 patients who met the inclusion criteria at out hospital from May 2023 to October 2023. Questionnaires were completed by patients, and biochemical indicators were obtained from past medical records. Univariate and multifactor analyses were used to find factors influencing sleep quality in patients on dialysis. Simple linear regression results showed that female, type of kidney primary disease, high systolic blood pressure (SBP), pruritus, pruritus frequency, restless legs syndrome (RLS), anxiety, and depression were associated with poor sleep quality. Blood biochemical parameters showed that low sodium and calcium levels and high ferritin levels were associated with poor sleep quality. Multiple linear regression statistics showed that female, pruritus, RLS, high SBP, depression, and high ferritin levels were associated with poor sleep quality. This study showed that female, chronic nephritis syndrome, high SBP, pruritus, RLS, low mood. and high ferritin levels were associated with poor sleep quality. Future development of individual nursing and targeted therapies is key to improving sleep quality in patients on dialysis.

Red cell distribution width to albumin ratio predicts treatment failure in peritoneal dialysis-associated peritonitis.

BACKGROUND: This study aims to investigate the potential correlation between baseline red cell distribution width (RDW) to albumin ratio (RAR) levels and treatment failure in peritoneal dialysis-associated peritonitis (PDAP) patients. METHODS: A retrospective single-center study was conducted on 286 PDAP patients. Logistic regression and generalized estimation equation (GEE) analyses were employed to assess the relationship between RAR and treatment failure. RESULTS: RAR emerged as a robust predictor of treatment failure in PDAP patients. Elevated RAR levels were associated with an increased risk of treatment failure, exhibiting a linear relationship. Even after adjusting for demographic and clinical variables, this association remained statistically significant. ROC analysis revealed that RAR outperformed RDW and albumin individually in predicting PDAP prognosis. CONCLUSION: This study highlights RAR as a superior prognostic marker for treatment failure in PDAP patients, offering new insights into risk assessment and management strategies for this challenging condition.

Decreased Peripheral Blood Lymphocyte Count Predicts Poor Treatment Response in Peritoneal Dialysis-Associated Peritonitis.

Purpose: Peripheral blood lymphocyte counts is a pivotal parameter in assessing the host's immune response during maladies and the equilibrium of the immune system which has been found to correlate with various diseases progression and prognosis. However, there was no study on patients with peritoneal dialysis-associated peritonitis (PDAP). We sought to investigate the prognostic value of baseline peripheral blood lymphocyte count in PDAP patients. Patients and methods: This retrospective study analyzed data from 286 PDAP patients over nine years. Episodes were categorized according to the tertiles of peripheral blood lymphocyte counts (Very Low Lymphocyte Count (VLLC) Group, <0.72×106/L; Low Lymphocyte Count (LLC) Group, 0.72-1.11×106/L; Normal Lymphocyte Count (NLC) Group, ≥ 1.11×106/L). Demographic, laboratory, and infection-related variables were analyzed. Cox regression and generalized estimating equation (GEE) models were used to estimate the association between lymphocyte counts and PDAP treatment failure, which included PD catheter removal and death. Results: After adjusting for other potential predictors, decreased lymphocyte counts exhibited an incremental relationship with the risk of treatment failure. The VLLC group indicated a 270% (95% CI, 1.168-6.247, P=0.020) and 273% (95% CI, 1.028-7.269, P=0.044) increased venture of treatment failure in Cox regression and GEE analyses, respectively, compared with the NLC group. As a continuous variable, the restricted cubic spline showed a linear negative correlation between lymphocyte counts and the treatment failure risk (P for overall = 0.026). The multivariate model C (combined lymphocyte count with baseline age, sex, dialysis age, Charlson Comorbidity index (CCI), etiology of kidney failure, hemoglobin, albumin, total bilirubin and infection type) showed an area under the curve of 0.824 (95% CI, 0.767-0.881, P=0.001) for the prediction of treatment failure. Conclusion: Lower lymphocyte counts are linked to increased PDAP treatment failure risk. This highlights lymphocyte count's potential as a prognostic indicator for PDAP.

The difference in diameter between radial artery and cephalic vein correlates with primary patency of radio-cephalic arteriovenous fistula.

INTRODUCTION: Autogenous radio-cephalic arteriovenous fistula (RCAVF) is preferred for chronic hemodialysis access. However, RCAVF still suffers from disappointing survival due to fistula dysfunction, with intimal hyperplasia (IH) as an underlying cause of this condition. The inconsistency of radial artery diameter (DRA) and cephalic vein diameter (DCV) is one of the factors affecting the shear disturbance, which is believed to trigger the onset of IH. However, there are no reports correlating the difference in DRA and DCV with RCAVF outcomes. METHODS: This was a retrospective cohort study. Consecutive patients (n = 233) with a new RCAVF created were included if they underwent duplex ultrasound examination to evaluate preoperatively the radial artery diameter (DRA) and cephalic venous diameter (DCV). We then calculated radial artery-cephalic vein diameter difference (DCV minus DRA, termed DCV-DRA hereafter) and evaluated the association of the preoperative DCV-DRA with primary patency of RCAVF at 12 months. Subgroup analysis was also performed to explore effect modification by age, gender, radial artery diameter, and cephalic vein diameter with DCV-DRA. RESULTS: After adjusting for age, gender, weight, and mean arterial pressure, the preoperative DCV-DRA was associated with primary patency of RCAVF at 12 months (adjusted Odds ratio [aOR], 1.524 per 1-mm increase; 95% confidence interval [95% CI], 1.048-2.218). The primary patency of RCAVF at 12 months was achieved in 69.4%, 71.8%,and 87.3% of patients with a preoperative DCV-DRA of ⩽-0.6 mm, (-0.5)-0.5 mm, and ⩾0.6 mm, respectively. P for trend was 0.029. Patients with DCV-DRA of ⩾0.6 mm had a much higher chance of 12-month patency than patients with DCV-DRA of ⩽-0.6 mm (aOR, 3.574; 95% CI, 1.276-10.010). Age, gender, radial artery diameter, and cephalic vein diameter did not modify the association of DCV-DRA with primary patency of RCAVF at 12 months. CONCLUSIONS: Preoperative DCV-DRA may be an under-recognized predictor of RCAVF patency.

Effect of Gua Sha therapy on patients with diabetic peripheral neuropathy: A randomized controlled trial.

OBJECTIVE: To examine the effect of Gua Sha therapy in the treatment of diabetic peripheral neuropathy (DNP). DESIGN: An open-label randomized controlled study was conducted with usual care as the control (60 subjects in Gua Sha group and 59 subjects in usual care group). Outcome measures included Toronto Clinical Scoring System (TCSS), Vibration Perception Threshold (VPT), Ankle Brachial Index (ABI), and fasting plasma glucose (FPG). There were 12 consecutive sessions of Gua Sha, one session per week. RESULTS: After the first cycle of Gua Sha intervention, only performance of sensory function measured by the VPT, and peripheral artery disease symptoms by the ABI were statistically significant differences between the two groups (both P values < 0.01), and the total TCSS score and the FPG level were no group differences (P = 0.14, and 0.25, respectively). At the eight-week and 12-week post intervention assessment, Gua Sha therapy significantly reduced severity of neuropathy symptoms, improved performance of sensory function, reduced peripheral artery disease, and better controlled plasma glucose by comparing with the control group (all P values < 0.01). The changes of mean scores of TCSS, VPT, ABI and the plasma glucose levels in the Gua Sha group showed a significant change from baseline to week 12, indicating that Gua Sha therapy induced progressive improvement in the management of DPN symptoms, sensory function, peripheral artery disease and glucose levels. No serious adverse events were reported in either arm. Gua Sha therapy in this study was effective, safe and well tolerated by patients. CONCLUSION: Gua Sha therapy appears to be effective at reducing the severity of DPN in a clinically relevant dimension, and at improving other health outcomes in patients with DPN. While this study found that Gua Sha therapy is a promising treatment in reducing the symptoms of patients with DPN, further, larger sample studies are required to confirm the effects of Gua Sha therapy in patients with DPN.
