The impact of clinical internship experience on nursing students' attitudes towards death and choices of end-of-life care: A self-control study.

AIM: This study aims to explore the impact of emergency department internships on the attitudes towards death among undergraduate nursing students and their preferences for end-of-life care settings. Additionally, the study analyzes the reasons behind nursing students' choices of end-of-life care settings and provides insights for improving undergraduate education on attitudes towards death and end-of-life care, and provide reference for the development of emergency hospice care. DESIGN: This study adopts an observational design with a self-controlled before-and-after approach. METHODS: A questionnaire survey was conducted with 96 nursing interns between July 2021 to June 2022. Demographic information and data on attitudes towards death, and preferences for end-oflife care location were collected by online questionnaire. Paired test were conducted to compare differences between groups. RESULTS: The study included a total of 96 nursing students with an average age of 21.11 years. The scores for the avoidance-acceptance dimension of death attitudes before and after the internship were 2.40 (1.80, 3.00) and 2.20 (1.60, 3.00), respectively, showing a significant difference (Z = -2.084, p = 0.037). Factors such as gender, experience in caring for critically ill or dying patients, knowledge of death education, and discussions about death at home were found to influence nursing students' attitudes towards death. Nursing students expressed a preference for receiving end-of-life care and treatment in their homes or in hospice/palliative care wards, while the intensive care unit, emergency department, and nursing homes were the least preferred settings. There were significant differences in nursing students' preferences for end-of-life care settings before and after the internship (p = 0.000). Importantly, the number of nursing students expressing a desire to receive end-of-life care in the emergency department increased from 2 to 7 after the internship, while the number of students not wanting end-of-life care in the emergency department decreased by 5.

Acute kidney injury in cancer patients receiving anti-vascular endothelial growth factor monoclonal antibody vs. immune checkpoint inhibitors: a retrospective real-world study.

BACKGROUND: Anti-vascular endothelial growth factor monoclonal antibody (anti-VEGF) or immune checkpoint inhibitors (ICIs) combined with chemotherapy are commonly administered to cancer patients. Although cancer patients receiving anti-VEGF or ICIs have been reported to experience an increased risk of acute kidney injury (AKI), comparative studies on the AKI incidence have not been evaluated. METHODS: Cancer patients receiving anti-VEGF or ICIs were retrospectively selected from the hospital information system of the First Affiliated Hospital of Wenzhou Medical University between Jan, 2020 and Dec, 2022 and were divided into two groups according to the treatment regimen: anti-VEGF group and ICIs group. The baseline characteristics were propensity-score matched. The primary outcome was sustained AKI. A comparison of cumulative incidence of sustained AKI was performed by Kaplan-Meier curves and log-rank test. Risks for outcomes were assessed using Cox proportional regression. RESULTS: A total of 1581 cancer patients receiving anti-VEGF (n = 696) or ICIs (n = 885) were included in the primary analysis. The ICIs group had a higher cumulative incidence of sustained AKI within one year than the anti-VEGF group (26.8% vs. 17.8%, P < 0.001). Among 1392 propensity score matched patients, ICIs therapy (n = 696) was associated with an increased risk of sustained AKI events in the entire population (HR 2.0; 95%CI 1.3 to 2.5; P = 0.001) and especially in those with genitourinary cancer (HR 4.2; 95%CI 1.3 to 13.2; P = 0.015). Baseline serum albumin level (> 35 g/l) was an important risk factor for a lower incidence of sustained AKI in the anti-VEGF group (HR 0.5; 95%CI 0.3 to 0.9; P = 0.027) and the ICIs group (HR 0.3; 95%CI 0.2 to 0.5; P < 0.001). CONCLUSIONS: Among cancer patients in this real-world study, treatment with ICIs increased incidence of sustained AKI in one year. Baseline serum albumin level was an important risk factor for sustained AKI. The risk factors for sustained AKI differed between the anti-VEGF group and the ICIs group. TRIAL REGISTRATION: The study has been registered at ClinicalTrials.gov (NCT06119347) on 11/06/2023.

Performance of continuous glucose monitoring in patients with acute respiratory failure: a prospective, single-center observational study.

OBJECTIVE: Continuous glucose monitoring (CGM) may have benefits in achieving glycemic control in critically ill patients. The aim of this study was to assess the accuracy of the Freestyle Libre H (professional version of the Libre Pro). in patients with acute respiratory failure (ARF) in the intensive care unit (ICU). METHODS: 52 adult patients with ARF were selected. The performance of CGM was evaluated using arterial blood glucose (aBG) and point-of-care (POC) glucose as reference values. Numerical accuracy was evaluated by the mean absolute relative difference (MARD), Bland-Altman analysis, and %15/15(the percentage of CGM values within 15 mg/dL or 15% of reference values <100 mg/dL or >100mg/dL, respectively), %20/20 and %30/30; Clinical accuracy was assessed by Clarke error grid analysis. RESULTS: 519 and 1504 pairs of aBG/CGM and POC/CGM glucose values were analyzed. The MARD values were 13.8% and 14.7%, respectively. The mean deviation of the Bland‒Altman analysis was 0.82 mmol/L and 0.81 mmol/L. %15/15, %20/20 and %30/30 of aBG values were 62.6%, 75.5%, and 92.4%, respectively; %15/15, %20/20 and %30/30 of POC values were 57.1%, 72.9%, and 88.7%, respectively. The Clarke error grid analysis showed that 97.8% and 99.3% of the values located in the (A+B) zone. Additionally, accuracy of CGM is not affected by general patient factors. CONCLUSION: This study demonstrated that the accuracy of CGM in patients with ARF is lower than that in most outpatients, and it is not affected by general patient factors. Whether CGM is beneficial to glucose management in ICU needs further evaluation.

Enhancing Emergency Nurses' Disaster Nursing Ability and Psychological Resilience: A Randomized Controlled Trial.

Objective: This study aimed to investigate emergency nurses' disaster nursing ability and psychological resilience, validate the effectiveness of a training system for disaster nursing ability based on psychological resilience, and verify the relationship between psychological resilience and disaster nursing ability among emergency nurses. Methods: A training system was developed to enhance psychological resilience and disaster nursing ability. A multicenter, randomized controlled experiment was conducted in five Grade III hospitals in Sichuan Province. A total of 93 emergency nurses were randomly assigned to the following three groups: the blank group, intervention group, and control group. The corresponding interventions were as follows: no intervention, psychological resilience, and nurses' disaster nursing ability training. Personal information forms, the Connor-Davidson Resiliency Scale, and the Nurses' Disaster Nursing Ability Assessment Scale were used in the survey. Results: There was no significant difference in the scores of psychological resilience and disaster nursing ability in the blank group in the pretest and posttest (P > 0.05). The disaster nursing ability of both the intervention and control groups significantly improved in the posttest (P < 0.05). Compared with the control group, the intervention group demonstrated significant improvement in psychological resilience in the posttest (P < 0.05). However, there was no statistical difference in psychological resilience scores in the control group in the pretest and posttest (P > 0.05). Conclusion: The study concluded that the psychological resilience and disaster nursing ability of emergency nurses could be enhanced through the implemented training system.

Clinical Efficacy and Short-Term Prognosis of Butylphthalide and Sodium Chloride Injection Compared to Edaravone in the Treatment of Patients with Acute Stroke.

Background: Acute stroke is characterized by rapid progression, high mortality, and disability rates, making it a significant focus in clinical research. Brain-protective agents, such as butylphthalide and edaravone, have emerged as important therapeutic options for acute stroke. Objective: This study aimed to explore how butylphthalide and edaravone promote healing in acute stroke, drawing on relevant data, literature, clinical experience, and personal concepts. Design: The study design involves a narrative review, which comprehensively explores the pathogenesis of stroke by referencing relevant data and literature. Clinical experience and personal insights were incorporated to provide a holistic understanding. The primary focus was analyzing the mechanisms through which butylphthalide and edaravone facilitate healing in stroke patients. Results: The review revealed that butylphthalide exhibited multiple beneficial effects, including the protection of mitochondria, reduction of the inflammatory response, enhancement of microcirculation, decrease in blood-brain barrier permeability, and improving nerve cell function. On the other hand, edaravone demonstrated its efficacy by reducing oxidative stress response, inhibiting inflammatory response, and regulating the metabolism of arachidonic acid and apoptosis. These findings highlight the distinct mechanisms through which butylphthalide and edaravone contribute to the healing process in patients with stroke. Conclusions: This study highlights the positive impact of butylphthalide and edaravone on the therapeutic effect and short-term prognosis in acute stroke patients. The findings provide valuable guidance for future research and enhance our understanding of these drugs' mechanisms, offering the potential for improved stroke management and patient outcomes.

Analysis of Resilience, Coping Style, Anxiety, and Depression Among Rescue Nurses on EMTs During the Disaster Preparedness Stage in Sichuan, China: A Descriptive Cross-Sectional Survey.

OBJECTIVE: The purpose of this study was to investigate the current situation and influencing factors of resilience, coping style, anxiety, and depression among rescue nurses on Emergency Medical Teams (EMTs) during the disaster preparedness stage, and to explore the relationship between resilience, coping style, anxiety, and depression. METHODS: A descriptive cross-sectional survey was used. The convenience sampling method was used to select rescue nurses from 4 national EMTs in Sichuan Province, China. CD-RISC, SCSQ, Zung SAS, and SDS were used as research tools. RESULTS: A total of 197 valid questionnaires were returned, with a 98.5% response rate. The results of multiple regression analysis showed that average monthly income, depression level, and coping style were the main factors affecting nurses' resilience. Resilience was significantly and positively correlated with coping style and negatively correlated with anxiety and depression. There were significant differences in SCSQ, Zung SAS, and SDS scores among Clusters. CONCLUSION: In the disaster preparedness stage, rescue nurses on EMTs have a medium level of resilience and good coping styles, but their levels of anxiety and depression are high. It is suggested that more attention should be devoted to the target population to formulate effective intervention plans, reduce psychological pressures, and improve their capacity for coping with disasters.

Pneumocystis pneumonia in patients with primary nephrotic syndrome.

OBJECTIVE: The aim of this study was to analyze the clinical features, risk factors, and outcomes of patients with primary nephrotic syndrome (PNS) who developed Pneumocystis pneumonia (PCP). MATERIALS AND METHODS: We systematically reviewed medical records from 18 PNS patients with PCP admitted to our hospital from April 2007 to April 2019. A total of 180 cases were randomly selected as controls from PNS inpatients without infection. RESULTS: In PCP patients, the mean age at presentation was 48.5 years, mean duration of prednisone treatment was 3.7 months, and mean prednisone dose on admission was 31.3 mg/d. Eight patients (44.4%) had coexisting infections, most often was Cytomegalovirus (4 patients); 11 patients (61.1%) had ICU admission, and 9 patients (50%) had mechanical ventilation. PCP patients had more prednisone, more immunosuppressive therapy, lower CD4+ cell counts and hemoglobin, and higher serum creatinine than those without infections (p < 0.05). All patients survived after treatment. CONCLUSION: PCP was not unusual in PNS patients, and the most important risk factors were prednisone usage, other immunosuppressive therapy, and a lower CD4+ cell count; however, these patients had a good outcome after sufficient treatment.

PRDX3 promotes resistance to cisplatin in gastric cancer cells.

Objective: This study aims to investigate peroxiredoxin 3 (PRDX3) expression in gastric cancer tissue and its effects on cisplatin resistance in gastric cancer cells and its possible mechanism. Methods: PRDX3 expression in human gastric cancer tissue microarrays was detected via immunohistochemistry. The PRDX3 small interfering RNA (siPRDX3 group) and the negative control siNC (siNC group) were transfected into AGS and MKN-74 cell lines, respectively, whereas a blank control group was set up. Each group was treated with different cisplatin concentrations (0, 5, 10, 15, 20, 25, and 30 µg/ml), and the half-inhibitory concentration (IC50) of each group of the two cell lines was calculated using the CCK8 assay. The corresponding IC50 concentration of the siPRDX3 group in the two cell lines was used to treat cells of each group. Flow cytometry was used to detect cell apoptosis, and Western blotting was used to detect the expression levels of cleaved caspase-3 and Bax in each group. Results: PRDX3 was overexpressed in gastric adenocarcinoma tissue compared with adjacent noncancer tissue (P = 0.0053). After cisplatin treatment, the IC50 in the siPRDX3 group of AGS cells (5.91 ± 0.18 µg/ml) and the siPRDX3 group of MKN-74 cells (3.48 ± 0.30 µg/ml) was significantly lower than in the corresponding siNC groups (10.01 ± 0.99 and 6.39 ± 0.70 µg/ml; P = 0.0022 and 0.0027, respectively). AGS cells (38.81% ± 1.69%) and MKN-74 cells (25.03% ± 2.80%) in the siPRDX3 group showed significantly higher apoptosis rates than in the corresponding siNC groups (23.17% ± 1.43% and 16.7% ± 1.39%; P = 0.0003 and 0.0099, respectively). The expression levels of cleaved caspase-3 and Bax were significantly higher in the siPRDX3 group of both cell lines than in the siNC group (P < 0.0001). Conclusion: PRDX3 increases the gastric cancer cell resistance to cisplatin by reducing apoptosis and thus may serve as a target to overcome cisplatin resistance.

Exercise interventions for older people at risk for frailty: A protocol for systematic review and meta-analysis.

BACKGROUND: Frailty is a state of age-related reduced physiological reserve characterized by an increased risk of adverse clinical outcomes. Studies have shown that exercise can improve frailty in older people. However, it remains to be seen which exercises will most improve the fitness of older people with frailty or those at the risk for frailty.Objective: This protocol aims to determine whether physical exercise can improve frailty in older people, and if which methods are most effective. METHODS: We searched the following databases for relevant articles published between January 1, 2012 and January 1, 2021: PubMed, EMBASE, the Cochrane Library, Wanfang, the China National Knowledge Infrastructure, Clinical Trials Database, and the Science Network. Two independent reviewers will carry out data extraction, discuss and resolve differences, and obtain consensus from the third author. We will select randomized control trials (RCTs) according to the preformulated inclusion criteria. The main outcomes in this study are scores from Fried Frailty Phenotype Criteria; the Frailty Trait Scale-short form; the SHARE Frailty Instrument; the FRAIL scale; the Gérontopôle Frailty Screening Tool; the Clinical Frailty Scale, the Rockwood and Mitnitsky Frailty Index; the Study of Osteoporotic Fractures Index; the Edmonton Frailty Scale; the Fatigue, Resistance, Ambulation, Illness and Loss of Weight Index; the Multidimensional Prognostic Index; the Tilburg Frailty Indicator; PRISMA-7; the Groningen Frailty Indicator; the Sherbrooke Postal Questionnaire; and the Kihon Checklist. Secondary outcomes are muscle strength, gait velocity, stair-climbing power, and level of spontaneous physical activity. If the heterogeneity test shows slight or no statistical heterogeneity, a fixed effects model will be used for data synthesis; otherwise, a random effects model will be used. We will develop a unified data extraction table that includes a number of parameters. The Cochrane Cooperative Bias Risk Tool will be used to evaluate the methodological quality of the selected RCTs. RevMan Manager 5.3 and STATA 14.0 will be used for data analysis if enough RCTs (more than 10) are identified and selected. RESULT: The final results will provide information on the effectiveness of intervention programs for frail older adul and further demonstrate which exercise programs are more effective and which methods can significantly improve frailty. CONCLUSION: This protocol will contribute to the development of more effective interventions for elderly individuals with frailty. ETHICS AND DISSEMINATION: This study applies existing literature references; therefore, ethical approval is not required. INPLASY REGISTRATION NUMBER: INPLASY202130107.

[Therapeutic effect of Actovegin on acute oral mucositis caused by radiotherapy].

PURPOSE： To explore the clinical effect of Actovegin in the treatment of acute oral mucositis in patients with radiotherapy. METHODS： One hundred and thirteen patients with acute oral mucositis caused by radiotherapy for nasopharyngeal carcinoma admitted to the Department of Oncology, the Fifth People's Hospital of Qinghai Province from July 2015 to September 2017 were randomly divided into the experimental group (57 cases) and control group (56 cases). Patients in the experimental group were treated with Aiweizhi, while patients in the control group were treated with new rehabilitation. The changes of VAS score, oral mucositis grade, serum CRP, IL-6, TGF-ß1 and TNF-α were compared between the 2 groups. The data were analyzed with SPSS 16.0 software package. RESULTS: Before treatment, there was no significant difference in VAS score between the 2 groups (P>0.05). After 1 week and 2 weeks of treatment, the VAS scores of the two groups were significantly lower than those before treatment (P<0.05). The VAS score of the experimental group was significantly lower than that of the control group (P<0.05). After 2 weeks of treatment, oral mucositis grade of the experimental group was significantly lower than that of the control group (P<0.05). There was no significant difference in serum CRP, IL-6, TGF-ß1, and TNF-α level between the 2 groups before treatment (P>0.05). After 2 weeks of treatment, the level of serum CRP, IL-6, TGF-ß1, and TNF-α in both groups was significantly lower than that before treatment (P<0.05). The serum level of CRP, IL-6, TGF-ß1 and TNF-α in the experimental group was significantly lower than that in the control group (P<0.05). CONCLUSIONS: Actovegin has a clear clinical effect on acute oral mucositis in patients with radiotherapy, which can significantly alleviate the pain of patients and reduce the level of serum inflammatory factors.

[Effects of different orthodontic treatments on sputum chemokines CX3CL1, RANKL/OPG levels in patients with malocclusion].

PURPOSE: To investigate the effects of different orthodontic treatments on gingival crevicular fluid chemokine CX3CL1, nuclear factor κB receptor activating factor ligand/osteoprotegerin(RANKL/OPG) levels in patients with malocclusion. METHODS: Ninety-six patients with malocclusion who were scheduled to undergo orthodontic treatment were randomly divided into four groups. All patients were treated with square wire appliance, and 0, 50, 150, 250 g of far-distal orthodontic force were given respectively. The levels of CX3CL1 and RANKL/OPG in gingival crevicular fluid were detected in four groups after 1, 2, 3, and 4 weeks of treatment. SPSS 25.0 software package was used for statistical analysis of the date. RESULTS: The levels of CX3CL1, RANKL and RANKL/OPG in the gingival crevicular fluid of the four groups were continuously increased after treatment for 1-3 weeks, and decreased after 4 weeks of treatment (P<0.05). The OPG in the gingival crevicular fluid was at a low level after 1-3 weeks of treatment. There was an increase after 4 weeks of treatment (P<0.05). The levels of CX3CL1, RANKL, OPG and RANKL/OPG in gingival crevicular fluid increased gradually in group A, B, C and D (P<0.05), and the differences between the groups were statistically significant (P<0.05). CONCLUSIONS: The levels of CX3CL1 and RANKL/OPG in gingival crevicular fluid are closely related to orthodontic force and treatment time, and can be used as an index to evaluate orthodontic treatment of alveolar bone remodeling.

Association of antiphospholipid antibodies with clinical activity and renal pathological activity in patients with lupus nephritis.

OBJECTIVES: This study aimed to investigate the association of antiphospholipid antibodies (aPL) with clinical activity and renal pathological activity in patients with lupus nephritis (LN). METHODS: Levels of anticardiolipin () antibodies, anti-ß2-glycoprotein I (anti-ß2-GPI) antibodies and lupus anticoagulant (LAC) were measured, and other clinical and pathological data were also obtained during the same period before renal biopsy. RESULTS: A total of 83 patients with LN were included in this study, 40 patients (48.2%) in the s positive group and 43 patients in the aPL negative group. LN patients with positive aPL had significantly higher SLEDAI (p = 0.012), more hematuria (p = 0.043), lower serum C3 (p = 0.003) and C4 (p = 0.014), and a higher pathological activity index (p = 0.012), more micro-thrombosis (p = 0.046) and more C3 deposits (p = 0.038) in the glomerulus than patients with negative aPL The level of IgG- was significantly correlated with SLEDAI and serum level of C3 (r = 0.44, p < 0.001; r = -0.39, p = 0.003, respectively). The level of IgM- was significantly correlated with SLEDAI, and serum levels of C3 and C4 (r = 0.27, p = 0.014; r = -0.22, p = 0.041; r = -0.23, p = 0.035, respectively). CONCLUSIONS: Our work suggests that aPL, especially, are correlated with both clinical activity and renal pathological activity in patients with LN.

Tuberculosis spondylitis in patients on hemodialysis: Clinical features, risk factors, and outcomes in 12 patients.

The aim of this study was to investigate the clinical features, risk factors and outcomes of tuberculosis spondylitis (TBS) in patients on hemodialysis (HD). We systematically reviewed medical records from 12 HD patients with TBS admitted to our hospital from April 2008 to April 2018. A total of 120 age- and sex-matched HD patients without infections were randomly selected as controls. The incidence of TBS in our patient group was 1.5/1000 per year. The average duration from initial symptoms to diagnosis was 45.4 days (range, 11-180 days). Neurosurgery was performed in 4 (33.3%) patients. TBS was cured or improved in 11 (91.7%) patients. HD patients with TBS had significantly lower albumin and Hb levels than controls (P = .03 and P = .01). These findings indicated that lower albumin and Hb levels were possible risk factors for TBS in patients on HD, most HD patients with TBS had a good outcome after anti-TB therapy with or without surgery.

Predictors of renal outcomes in crescentic and mixed class of ANCA-associated glomerulonephritis.

BACKGROUND: The aim of this study was to investigate the predictors of renal outcomes in crescentic and mixed class of ANCA-associated glomerulonephritis. MATERIALS AND METHODS: We systematically reviewed the medical records of patients with ANCA-associated glomerulonephritis admitted to our hospital from December 2008 to December 2018, and found 30 patients with crescentic and 40 patients with mixed ANCA-associated glomerulonephritis. RESULTS: End-stage renal disease developed in 33.3 and 25% patients over a median follow-up of 45.1 and 46.7 months in the crescentic and mixed group, respectively. There was no significant difference in renal survival rates between the two histological subgroups (log-rank p = 0.558). In the Cox regression model, old age, lower estimated glomerular filtration rate (eGFR), lower normal glomeruli ratio, and a higher tubular atrophy and interstitial fibrosis ratio were significantly associated end-stage renal disease (p < 0.05 for all). Among our patients, 17.1% were at low risk, 57.1% were at medium risk, and 25.7% were at high risk according to antineutrophil cytoplasmic antibody renal risk score and end-stage renal disease developed in 8.3, 40, and 66.7%, respectively (p = 0.024). CONCLUSION: These findings indicated that the renal risk score was a better prognostic tool than Berden's classification in a cohort with crescentic and mixed histologic categories.

Prognostic value of serum albumin-to-creatinine ratio in patients with acute myocardial infarction: Results from the retrospective evaluation of acute chest pain study.

The long-term association between serum albumin-to-creatinine ratio (sACR) and poor patient outcomes in acute myocardial infarction (AMI) remains unclear. This study aimed to determine whether sACR was a predictor of poor long-term survival in patients with AMI.This was a study of patients with AMI in the emergency department (ED) from the retrospective multicenter study for early evaluation of acute chest pain (REACP) study. The patients were categorized into tertiles (T1, T2, and T3) based on the admission sACR (0.445 and 0.584 g/µmol). Baseline sACR at admission to the ED was predictive of adverse outcomes. The primary outcome was all-cause mortality within the follow-up period. Cox proportional hazards models were performed to investigate the association between sACR and all-cause mortality in patients with AMI.A total of 2250 patients with AMI were enrolled, of whom 229 (10.2%) died within the median follow-up period of 10.7 (7.2-14.6) months. Patients with a lower sACR had higher all-cause mortality and adverse outcomes rates than patients with a higher sACR. Kaplan-Meier survival analysis showed that patients with a higher sACR had a higher cumulative survival rate (P < .001). Cox regression analysis showed that a decreased sACR was an independent predictor of all-cause mortality [T2 vs T1: hazard ratio (HR); 0.550, 95% confidence interval (95% CI), 0.348-0.867; P = .010 and T3 vs T1: HR, 0.305; 95% CI, 0.165-0.561; P < .001] and cardiac mortality (T2 vs T1: HR, 0.536; 95% CI, 0.332-0.866; P = .011 and T3 vs T1: HR, 0.309; 95% CI, 0.164-0.582, P < .001).The sACR at admission to ED was independently associated with adverse outcomes, indicating that baseline sACR was a useful biomarker to identify high-risk patients with AMI at an early phase in ED.

Clinical features, risk factors, and outcomes of septic arthritis in patients on maintenance hemodialysis.

The aim of this study was to investigate the clinical features, risk factors, and outcomes of septic arthritis in patients on maintenance hemodialysis (HD). We systematically reviewed medical records of 16 HD patients with septic arthritis admitted to our hospital from April 2008 to April 2018. A total of 16 HD in patients with bloodstream infection but without septic arthritis were randomly selected as controls. The incidence of septic arthritis in our patient group was 0.2% per year. Organisms isolated were Staphylococcus aureus in 11 (68.7%), Gram-negative bacilli in 3, streptococci in 1, and fungi in 1. Patients with septic arthritis were significantly older (72.7 ± 9.4 vs 63.5 ± 8.7 years, p = 0.035) and had more joint diseases (62.5% vs 12.5%, p = 0.003) and a longer duration of hospitalization (35.2 ± 5.7 vs 22.1 ± 3.5 days, p = 0.021) than the control group. In a logistic regression analysis, patients with older age and more joint diseases were more likely to have septic arthritis compared with controls (OR = 1.39, p = 0.024 and OR = 3.24, p = 0.003, respectively). These findings indicate that old age and joint diseases (osteoarthritis or inflammatory arthritis) were independent risk factors for septic arthritis in patients on HD when bloodstream infection occurred. Key Points • Patients with septic arthritis were significantly older and had more joint diseases than the control group. • Old age and joint diseases are independent risk factors for septic arthritis in patients on HD when bloodstream infection occurs.

Effects of parathyroid hormone and vitamin D supplementation on stroke among patients receiving peritoneal dialysis.

BACKGROUND: Continuous ambulatory peritoneal dialysis (CAPD) patients have a high incidence of stroke and commonly have increased parathyroid hormone levels and vitamin D insufficiency. We seek to investigate the incidence of stroke and the role of parathyroid hormone and vitamin D supplementation in stroke risk among CAPD patients. METHODS: This study employed a retrospective design. We enrolled a Chinese cohort of 980 CAPD patients who were routinely followed in our department. The demographic and clinical data were recorded at the time of initial CAPD and during follow-up. The included patients were separated into non-stroke and stroke groups. The effects of parathyroid hormone and vitamin D supplementation on stroke in CAPD patients was evaluated. The primary endpoint is defined as the first occurrence of stroke, and composite endpoint events are defined as death or switch to hemodialysis during follow-up. RESULTS: A total of 757 eligible CAPD patients with a mean follow-up time of 54.7 (standard deviation, 33) months were included in the study. The median incidence of stroke among our CAPD patients was 18.9 (interquartile range, 15.7-22.1) per 1000 person-years. A significant nonlinear correlation between baseline iPTH and hazard of stroke (p-value of linear association = 0.2 and nonlinear association = 0.002) was observed in our univariate Cox regression analysis, and low baseline iPTH levels (≤150 pg/ml) were associated with an increased cumulative hazard of stroke. Multivariate Cox regression analysis indicated a significant interaction effect between age and iPTH after adjusting for other confounders. Vitamin D supplementation during follow-up was a predictive factor for stroke in our cohort. CONCLUSIONS: CAPD patients suffered a high risk of stroke, and lower iPTH levels were significantly correlated with an increased risk of stroke. Nevertheless, vitamin D supplementation may reduce the risk of stroke in these patients.

Long-term predictive value of acute kidney injury classification in diffuse proliferative lupus nephritis with acute kidney injury.

BACKGROUND: The long-term predictive ability of acute kidney injury (AKI) classification based on "Kidney Disease: Improving Global Outcomes"(KDIGO) AKI diagnosis criteria has not been clinically validated in diffuse proliferative lupus nephritis (DPLN) patients with AKI. Our objective was to assess the long-term predictive value of KDIGO AKI classification in DPLN patients with AKI. METHODS: Retrospective cohort study was conducted by reviewing medical records of biopsy-proven DPLN patients with AKI from the First Affiliated Hospital of Wenzhou Medical University between Jan 1, 2000 and Dec 31, 2014. Multivariate Cox regression and survival analysis were performed. RESULTS: One hundred sixty-seven DPLN patients were enrolled,82(49%) patients were normal renal function (No AKI), 40(24%) patients entered AKI-1 stage (AKI-1), 26(16%) patients entered AKI-2 stage (AKI-2) and 19(16%) patients entered AKI-3 stage (AKI-3). The mean follow-up of all patients was 5.1 ± 3.8 years. The patient survival without ESRD of all patients was 86% at 5 years and 79% at 10 years. The patient survival rate without ESRD at 10 yr was 94.5% for No AKI patients, 81.8% for AKI-1 patients, 44.9% for AKI-2 patients and 14.6% for AKI-3 patients. The area under the ROC curve for KDIGO AKI classification to predict the primary end point was 0.83 (95% CI: 0.73-0.93) (P < 0.001). In Cox regression analysis, AKI stage was independently associated with primary endpoint, with an adjusted hazard ratio (HR) of 3.8(95% CI 2.1-6.7, P < 0.001). CONCLUSION: Severity of AKI based on KDIGO AKI category was associated with progression to ESRD in DPLN patients. Analytical data also confirmed the good discriminative power of the KDIGO AKI classification system for predicting long-term prognosis of DPLN patients with AKI.

Serum uric acid is an independent predictor of renal outcomes in patients with idiopathic membranous nephropathy.

PURPOSE: Accumulating evidence suggests that a relationship exists between serum uric acid (UA) and the progression of chronic kidney disease (CKD), but information regarding idiopathic membranous nephropathy (IMN) is limited. METHODS: Patients with renal biopsy-confirmed diagnosis of IMN between 2009 and 2017 were identified. The demographic and clinical data recorded at the time of renal biopsy were considered the baseline values. The included cases were separated into three groups based on tertiles of the baseline serum UA level, and the relationship between serum UA and poor renal outcome was investigated by receiver operating characteristic (ROC) and time-event analyses. The primary endpoint was poor renal outcome, which was defined as a decrease in the estimated glomerular filtration rate to 50% of the baseline level or progression to end-stage renal disease during the follow-up. RESULTS: Of 989 cases, 572 eligible patients were included. During a median of 18 months of follow-up, 45 (7.9%) patients progressed to the primary endpoint. Both baseline serum UA and time-averaged UA levels could be used for discrimination of renal outcomes, but the difference was not significant (p value = 0.6). Our Cox regression analysis further demonstrated that baseline serum UA was an independent predictor of poor renal outcome in IMN patients, and subgroup analysis revealed a gender difference in the predictive effect of serum UA. CONCLUSIONS: Our study demonstrated that baseline serum UA was an independent predictor of poor renal outcome in patients with IMN, and a gender difference in the predictive effect was observed in our cohort.
