Objective To investigate the clinical characteristics and prognosis of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis with acute kidney injury (AKI) as the first manifestation, and provide new ideas for the prevention and treatment of this disease. Methods A retrospective analysis was performed on 144 patients diagnosed with ANCA-associated vasculitis in Affiliated Hospital of Southwest Medical University between August 2013 and March 2020. The patients were divided into AKI group and non-AKI group according to whether they were complicated with AKI at admission, and the differences in clinical characteristics were analyzed. The risk factors were screened by multiple logistic regression analysis. Results Among the 144 patients with ANCA-associated vasculitis, 30 cases (20.8%) were complicated with AKI at admission, and 70 cases (48.6%) died by the end of follow-up. There were 16 death cases (53.3%) in the AKI group, and 54 death cases (47.4%) in the non-AKI group, but the difference was not statistically significant (P>0.05). Single-factor analyses showed that in the AKI group, the pre-admission incidence of hematuria, neutrophil count, serum creatinine, systolic blood pressure, and Birmingham Vasculitis Activity Score were higher than those in the non-AKI group, while the red blood cell count and estimated glomerular filtration rate (eGFR) were lower than those in the non-AKI group, and the differences were statistically significant (P<0.05). Multiple logistic regression analysis showed that the neutrophil count [odds ratio (OR)=1.172, 95% confidence interval (CI) (1.003, 1.371), P=0.046] and eGFR [OR=0.942, 95%CI (0.907, 0.979), P=0.002] were independent influencing factors for AKI. Conclusions Elevated neutrophil count is an independent risk factor for ANCA-associated vasculitis complicated with AKI. It has certain guiding significance for clinical work. Early identification and intervention of these patients may contribute to reduce the case fatality rate and improve prognosis.
ObjectiveTo conduct a Meta-analysis to determine the clinical effect of protocol biopsy (PB)-monitored therapy after renal transplantation.MethodsPubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Standards Database and VIP Database for Chinese Technical Periodicals were searched for trials comparing the efficacy of timely intervention under PB surveillance with the conventional treatment. The quality of included studies was assessed and Meta-analysis was conducted by RevMan 5.3 software.ResultsSix randomized controlled trials met our inclusion criteria, including 698 cases. No significant difference was found between the PB group and the control group in 1-year [relative risk (RR)=0.99, 95% confidence interval (CI) (0.97, 1.01), P=0.39] and 2-year recipient survival rate [RR=1.00, 95%CI (0.97, 1.02), P=0.72]. Graft survival rate after 1 year [RR=1.01, 95%CI (0.99, 1.04), P=0.29] and 2 years [RR=1.02, 95%CI (0.99, 1.06), P=0.19] were also statistically similar. No statistical difference was found in glomerular filtration rate between the two groups [mean difference (MD)=0.45 mL/(min·1.73 m2), 95%CI (–3.77, 4.67) mL/(min·1.73 m2), P=0.83]. Renal function of PB group, monitored by serum creatinine, was superior to the control group [MD=–0.46 mg/dL, 95%CI (–0.63, –0.29) mg/dL, P<0.000 01]. No statistical difference was found in infection between the two groups [RR=1.23, 95%CI (0.69, 2.19), P=0.48].ConclusionsOur study did not suggest PB for every kidney transplantation recipient. However, long-term randomized controlled trials with larger sample size would be necessary to determine whether PB was effective for specific populations.
ObjectiveTo systematically review the efficacy and safety of transfemoral transcatheter aortic valve replacement (TFTAVR) under local anesthesia (LA) and general anesthesia (GA). MethodsElectronic databases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang and CBM were searched to collect randomized controlled trial and cohort studies on clinical outcomes of TFTAVR under LA and GA from inception to September 2020. Two authors independently screened literature, extracted data and assessed the quality of studies, and a meta-analysis was performed by using Stata 16.0 software. ResultsA total of 30 studies involving 52 087 patients were included in this study. There were 18 719 patients in the LA group and 33 368 patients in the GA group. The results of meta-analysis showed that the in-hospital all-cause mortality rate [RR=0.65, 95%CI (0.45, 0.94), P=0.021], 30-day all-cause mortality rate [RR=0.73, 95%CI (0.62, 0.86), P＜0.001], 30-day stroke [RR=0.82, 95%CI (0.68, 0.98), P=0.025], cardiac arrest [RR=0.50, 95%CI (0.34, 0.73), P＜0.001], ICU stay time [RR=−6.86, 95%CI (−12.31, −1.42), P=0.013], and total hospital stay time [RR=−2.02, 95%CI (−2.59, −1.45), P＜0.001] in the LA group were all better than those in the GA group. There was no significant difference in the in-hospital stroke [RR=0.83, 95%CI (0.69, 1.00), P=0.053], in-hospital myocardial infarction (MI) [RR=1.74, 95%CI (0.43, 7.00), P=0.434], or 30-day MI [RR=0.77, 95%CI (0.42, 1.42), P=0.404] between the two groups. ConclusionLA provides a safe and effective way to induce sedation without intubation, and may be a good alternative to GA for TFTAVR.
ObjectiveTo systematically review the effect of self-management intervention on the prevention and management of lymphedema in breast cancer patients. MethodsCochrane Library, Embase, PubMed, Web of Science, CINAHL, PsycINFO, SinoMed, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on self-management intervention on the prevention and management of lymphedema in breast cancer patients, from database inception to June 16. Two reviewers independently screened the literature, extracted data and assessed the risk of biasof the included studies. Meta-analysis was performed using RevMan 5.4 software. ResultsA total of 37 references were included, comprising 25 randomized controlled trials (RCTs), 12 controlled clinical trials (CCTs), and a total of 3 697 patients. There were 26 studies in the meta-analysis, and the results of the meta-analysis showed that, compared with the control group, patients in the intervention group exhibited better performance in lymphedema management-related behaviors SMD=2.65, 95%CI(1.53 to 3.78), P<0.01, symptoms related to lymphedema SMD=−2.01, 95%CI (−3.66 to −0.37), P<0.05, occurrence of lymphedema RR=0.37, 95%CI (0.32 to 0.45), P<0.01, upper limb function SMD=−1.88, 95%CI (−2.83 to −0.92), P<0.01, quality of life SMD=2.79, 95%CI (2.05 to 3.54), P<0.01, and the difference was statistically significant. The intervention mainly included information support, material support, emotional support and decision support. ConclusionThere are currently a variety of self-management interventions, but they mainly focus on information support. Self-management interventions can improve the self-management behavior of breast cancer patients with lymphedema and reduce the impact of lymphedema on patients.
