SAA、hs-CRP、IL-6联合检测在儿童感染性疾病中的诊断价值

目的:分析SAA、hs-CRP、IL-6联合检测在儿童感染性疾病中的诊断价值。方法:选择2019年1月~2020年10月某院收治的72例感染性疾病患儿开展研究,根据患儿的病原体检测结果划分为病毒感染组和细菌感染组各36例,另选择同期体检的36名健康儿童作为研究的参照组,分别比较3组的SAA、hs-CRP、IL-6等指标水平的差异。结果:细菌感染组的SAA、hs-CRP、IL-6等指标水平及阳性率均高于病毒感染组、参照组,同时病毒感染组的SAA、hs-CRP、IL-6等指标水平及阳性率高于参照组(P<0.05);SAA、hs-CRP、IL-6联合诊断的敏感度、准确度、阳性预测值、阴性预测值均高于SAA、hs-CRP、IL-6三个指标单独检测的敏感度、准确度、阳性预测值、阴性预测值,差异有统计学意义(P<0.05);联合检测的特异度与单独检测特异度对比无统计学意义(P>0.05)。结论:SAA、hs-CRP、IL-6联合诊断在儿童感染性疾病中具备较高的诊断价值,临床可将SAA、hs-CRP、IL-6作为该病的诊断辅助指标,有效提高疾病的诊断准确性。     

Impact of COVID-19 and malaria coinfection on clinical outcomes: a retrospective cohort study

ObjectivesDespite the possibility of concurrent infection with COVID-19 and malaria, little is known about the clinical course of coinfected patients. We analysed the clinical outcomes of patients with concurrent COVID-19 and malaria infection.MethodsWe conducted a retrospective cohort study that assessed prospectively collected data of all patients who were admitted between May and December 2020 to the Universal COVID-19 treatment center (UCTC), Khartoum, Sudan. UCTC compiled demographic, clinical, laboratory (including testing for malaria), and outcome data in all patients with confirmed COVID-19 hospitalized at that clinic. The primary outcome was all-cause mortality during the hospital stay. We built proportional hazard Cox models with malaria status as the main exposure and stepwise adjustment for age, sex, cardiovascular comorbidities, diabetes, and hypertension.ResultsWe included 591 patients with confirmed COVID-19 diagnosis who were also tested for malaria. Mean (SD) age was 58 (16.2) years, 446/591 (75.5%) were males. Malaria was diagnosed in 270/591 (45.7%) patients. Most malaria patients were infected by Plasmodium falciparum (140/270; 51.9%), while 121/270 (44.8%) were coinfected with Plasmodium falciparum and Plasmodium vivax. Median follow-up was 29 days. Crude mortality rates were 10.71 and 5.87 per 1000 person-days for patients with and without concurrent malaria, respectively. In the fully adjusted Cox model, patients with concurrent malaria and COVID-19 had a greater mortality risk (hazard ratio 1.43, 95% confidence interval 1.21-1.69).DiscussionCoinfection with COVID-19 and malaria is associated with increased all-cause in-hospital mortality compared to monoinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).     

Neutrophil-to-Lymphocyte Ratio Predicts Cancer Outcome in Locally Advanced Clear Renal Cell Carcinoma

BackgroundTo evaluate the association of neutrophil-to-lymphocyte ratio (NLR) with recurrence-free survival (RFS) and overall survival (OS) in patients with locally advanced nonmetastatic clear cell renal cell carcinoma (ccRCC) undergoing radical nephrectomy.Material and MethodsWe retrospectively identified 880 nephrectomies performed between January 2009 and December 2016 in a single center, reviewed data from 478 radical nephrectomies for kidney tumors and identified 187 patients with locally advanced nonmetastatic ccRCC (pT3-T4 N0M0). NLR was obtained preoperatively and calculated by dividing absolute neutrophil count by absolute lymphocyte count. OS and RFS were evaluated by the Kaplan–Meier method. Cox proportional-hazards regression models were used to evaluate predictors of RFS and OS.ResultsAmong 187 patients with ccRCC (mean age 63.4 ± 11.5 years; 118 [63.1%] male), the median follow-up was 48.7 months. On univariate analysis, in patients with Fuhrman nuclear grade of differentiation 3-4, the median time to recurrence was significantly shorter with NLR ≥ 4 than < 4 (24 vs. 55 months, P = .045). On multivariable analysis adjusted for NLR ≥ 4, among all variables analyzed (NLR, microvascular invasion, sarcomatoid differentiation, tumor size and body mass index), only nuclear grade of differentiation was an independent predictor of recurrence (hazard ratio 2.18; 95% confidence interval 1.07-4.92, P = .03). The 3-year OS had no statistically significant difference between patients with NLR ≥ 4 or < 4.ConclusionFor patients with locally advanced, nonmetastatic ccRCC, RFS was reduced with high nuclear grade of differentiation and high preoperative NLR. These findings suggest an association between higher NLR and worse outcomes in locally advanced ccRCC.

中西医结合治疗卵巢储备功能减退患者成功妊娠二例并文献复习

卵巢储备功能减退（diminished ovarian reserve，DOR）是卵巢因素所致不孕症的主要原因之一，西医临床治疗方法主要依赖于口服提高卵巢储备功能的药物、人工激素周期替代疗法和辅助生殖技术助孕，中医运用补肾健脾法治疗DOR具有不良反应少、疗效持久、治疗手段多样化等优势。报告2例在常规西医治疗基础上应用中医补肾健脾法综合治疗DOR患者成功妊娠的情况，强调个体化中西医结合治疗方案对于解决疑难病证的重要性，为临床应用中医药治疗DOR患者提供证据。
