  • Comparison of vascular access infection incidence of hemodialysis patients during epidemic and non-epidemic period of COVID-19

    Objective To explore the vascular access infection (VAI) incidence of hemodialysis patients during the the maximum spread of the COVID-19 epidemic (epidemic period) compared with the corresponding period with no local cases of COVID-19 (control period). Methods A single-center, retrospective study was carried out. Adult patients who underwent hemodialysis at the Department of Blood Purification Center, the Affiliated Hospital of Xuzhou Medical University during the epidemic period between December 7, 2022 and February 23, 2023 and the control period between December 7, 2020 and February 23, 2021 were selected. The incidence of local access site infection (LASI) and access related bloodstream infection (ARBSI) in included patients were observed and compared. ResultsA total of 1 401 patients were included. Among them, there were 737 cases during the epidemic period and 664 cases during the control period. There was no statistically significant difference in the age, gender, and duration of catheterization among patients of different periods and pathway types (P>0.05). There was no statistically significant difference in the occurrence of LASI between the epidemic period and the control period (χ2=1.800, P=1.180). There was a statistically significant difference in the occurrence of ARBSI between the epidemic period and the control period [χ2=4.610, relative risk (RR)=2.575, 95% confidence interval (CI) (1.053, 6.298), P=0.032]. There was no statistically significant difference in the incidence of LASI and ARBSI at different stages in patients with arteriovenous fistula and unnel-cuffed catheters (TCC) (P>0.05). There were statistically significant differences in the incidence of LASI [χ2=4.898, RR=3.832, 95%CI (1.058, 13.885), P=0.027] and ARBSI [χ2=7.150, RR=4.684, 95%CI (1.333, 16.460), P=0.005] among non cuffed catheters (NCC) patients at different stages. TCC patients might experience LASI (P<0.05) during the epidemic period and ARBSI (P<0.05) during the control period compared with the arteriovenous fistula patients; both central venous catheterization and NCC patients might experience LASI and ARBSI during the control period (P<0.05). Conclusion Targeting COVID-19 prevention may be associated with the reduction of vascular access infection in hemodialysis patients, in particular in NCC patients.

  • Veno-venous extracorporeal membrane oxygenation for a Stanford type A aortic dissection patient combined with postoperative respiratory failure and COVID-19: A case report

    During the new coronavirus disease 2019 (COVID-19) pandemic, there has been controversy over whether emergency surgical management should be performed or not in the patients with COVID-19. Stanford type A aortic dissection is a very urgent life-threatening disease, and guidelines recommend surgical treatment for patients with type A aortic dissection in the first instance. However, intraoperative extracorporeal circulation can be fatal to patients recovering from COVID-19. During the pandemic, extracorporeal membrane oxygenation (ECMO) has played an important role in supporting COVID-19 patients with acute respiratory failure. This article reports a successful V-V ECMO treatment for a Stanford type A aortic dissection patient, who suffered respiratory failure caused by COVID-19 after emergency surgery.

  • Strategies for the standardized management of acute kidney injury associated with coronavirus disease 2019

    Most patients with coronavirus disease 2019 (COVID-19) have a good prognosis, but a certain proportion of the elderly and people with underlying diseases are still prone to develop into severe and critical COVID-19. Kidney is one of the common target organs of COVID-19. Acute kidney injury (AKI) is a common complication of severe COVID-19 patients, especially critical COVID-19 patients admitted to intensive care units. AKI associated with COVID-19 is also an independent risk factor for poor prognosis in patients. This article mainly focuses on the epidemiological data, possible pathogenesis, diagnostic criteria, and prevention and treatment based on the 5R principle of AKI associated with COVID-19. It summarizes the existing evidence to explore standardized management strategies for AKI associated with COVID-19.

  • Clinical features of infant cytomegalovirus infection

    Objective To observe the ocular clinical features of infantile cytomegalovirus (CMV) infection. MethodsA retrospective clinical study. From March 2019 to July 2021, 876 eyes of 438 children with CMV infection who visited Department of Ophthalmology of Henan Provincial Children's Hospital were included in the study. Among them, there were 254 males and 184 females; the age ranged from 3 days to 11 months; the gestational weeks were 28 to 42 weeks; the birth weight was 1 120 to 8 900 g. There were 384 and 54 full-term and premature infants, respectively. Fundus examination was performed in 385 cases (770 eyes) after medical consultation; 53 cases (106 eyes) of premature infants were routinely screened. CMV retinitis (CMVR) was divided into granular type and fulminant type. Patients with CMV-related diseases with moderate to severe symptoms were given intravenous drip and/or oral ganciclovir; patients with severe fundus vasculitis were combined with intravitreal injection of ganciclovir. The follow-up period was from 4 to 28 months, and the characteristics of eye lesions, systemic comorbid diseases and treatment outcomes were observed. ResultsThere were 516 eyes of 258 cases with normal fundus (58.9%, 258/438); 291 eyes of 180 cases with CMVR (41.1%, 180/438), of which binocular and monocular were 111 (61.7%, 111/180) and 69 (38.3%, 69/180) cases. Among the 291 eyes of CMVR, 281 eyes (96.6%, 281/291) of granular type; yellow-white point-like opacity and/or retinal hemorrhage; 10 eyes (3.4%, 10/291) of fulminant type; fundus Showed a typical "cheese ketchup-like" and vascular white sheath-like changes. Among the 180 children with CMVR, 72 patients (118 eyes) were given systemic intravenous drip and/or oral ganciclovir; 5 patients (10 eyes) were given intravitreal ganciclovir, all of which were fulminant CMVR. At the last follow-up, fundus lesions regressed significantly in 100 eyes of 61 cases; 18 eyes of 11 cases had old lesions or uneven retinal pigment; 108 cases were not treated. ConclusionThe most common fundus manifestation of CMV infection in infants is granular retinitis, and fulminant retinitis is more severe, and the lesions can be significantly regressed after timely antiviral treatment.

  • 病毒感染在慢性阻塞性肺疾病急性发作中的作用

    慢性阻塞性肺疾病( COPD) 是一种进行性肺功能下降的呼吸系统慢性疾病, 在全世界是第四位导致死亡的原因, 由其导致的误工、医疗等费用巨大。另外, COPD 急性发作( AECOPD) 是导致生活质量下降和肺功能减退的主要原因[ 1] 。尽管AECOPD是一个严重的临床和经济问题, 然而, 关于AECOPD的发生机制目前尚不完全清楚。目前认为感染是独立的导致AECOPD 最重要的原因, 在所有AECOPD的病因中约占70% 。关于细菌感染在AECOPD 中的地位, 由于细菌相对较易分离、有明确治疗效果等, 容易确认, 而病毒相对难于分离和检测, 治疗效果相对不佳, 且人们对其重要性缺乏认识等, 在AECOPD 中的重要性研究较少。本文综述了近年研究中发现的病毒感染在AECOPD 中作用。......

  • 新型冠状病毒感染伴发癫痫及其发病机制与脑电图改变

    新型冠状病毒感染(Corona virus disease 2019,COVID-19)是一种由冠状病毒(SARS-CoV-2)导致的新型传染性疾病。关于COVID-19与癫痫之间的关系,有研究认为癫痫发作和COVID-19无明显关系;但也有不少学者认为,癫痫发作是COVID-19的继发症状,甚至是早期症状。COVID-19患者中癫痫发作发生率为0.08%~1.9%。COVID-19出现癫痫发作的直接发病机制是,SARS-COV-2能够直接进入并感染中枢神经系统,引起脑膜炎和脑炎,从而引起癫痫发作。间接发病机制包括:中枢神经系统炎症(细胞因子风暴)、血-脑屏障的破坏、凝血异常、脑卒中、线粒体功能异常、电解质紊乱。新发作和频发癫痫发作的患者可能导致预后更差,死亡率更高。COVID-19伴发癫痫患者中脑电图(Electroencephalogram,EEG)改变的主要表现为:基本节律不同程度的慢化、节律性慢活动、癫痫样放电(包括周期性放电和散在性棘波、尖波等)。癫痫患者EEG的异常部位主要分布在额叶,然而,异常EEG表现并无特异性。

  • Impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients: A systematic review and meta-analysis

    Objective To explore the impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. MethodsThe Medline, EMbase, CENTRAL, CNKI, Wanfang Data, VIP and China Biology Medicine from inception to May 2023 were searched by computer for studies about impact of SARS-CoV-2-positive donors on the prognosis of heart transplant recipients. The data were extracted from all the relevant literatures, and the quality of the data was assessed using the Newcastle-Ottawa Scale (NOS). All statistical analyses were conducted by the Stata 11.0 software. Results A total of 10 studies (NOS score ranging from 5 to 9 points) involving 643 patients were enrolled. The pooled results demonstrated that the pooled mortality of heart transplant recipients from SARS-CoV-2-positive donors was 4% (95%CI 2% to 5%). And the incidence of composite outcome, regarding graft failure, rejection and death as poor prognosis, was 7% (95%CI 5% to 9%). Besides, compared with recipients from SARS-CoV-2-negative donors, the pooled odds ratio (OR) value of death of SARS-CoV-2-positive donors was 0.68 (95%CI 0.38 to 1.22, Z=1.28, P=0.200). The pooled OR value of rejection rate was 0.41 (95%CI 0.27 to 0.64, Z=3.97, P<0.005). For the composite outcome, the pooled OR value was 0.50 (95%CI 0.37 to 0.69, Z=4.30, P<0.005). In addition, there was no statistical difference in the length of hospital stay between heart transplant recipients from SARS-CoV-2-positive donors and negative donors (SMD=–0.03, 95%CI –0.22 to 0.15, Z=0.36, P=0.720). Conclusion The application of heart from SARS-CoV-2-positive donor for transplantation is safe and feasible. However, further prospective studies with longer follow-up are still needed to verify its impact on long-term outcomes.

  • Analysis of thrombotic events and mortality in patients with sever pneumonia in intensive care unit

    Objective To explore the thromboembolic events and mortality in patients with different types of severe pneumonia, and to analyze the related high-risk factors. Methods A total of 161 severe pneumonia patients who admitted in intensive care unit from January 2018 to February 2023 were included in the study. The patients were divided into a COVID-19 group (n=88) and a community-acquired pneumonia (CAP) group (n=73) according to the type of pneumonia, and divided into a thrombosis group and a non-thrombosis group according to the occurrence of thrombosis. The patients were followed-up until discharge or in-hospital death, registering the occurrence of thrombotic events. Results During the in-hospital stay, 32.9% of CAP and 36.4% of COVID-19 patients experienced thrombotic events (P>0.05). In CAP group all the events (including 24 paitents) were venous thromboses, while in COVID-19 group 31 patients were venous and 3 were arterial thromboses (2 were cerebral infarction, and 1 with myocardial infarction). There were statistically significant difference in gender, age, venous thromboembolism score (VTE score), activated partial thromboplastin time (APTT), and procalcitonin (PCT) between the TE group and the Non-TE group. Logistic regression analysis showed that thrombotic events was associated with sex, age and APTT; gender (female: OR=2.47, 95%CI 1.13 - 5.39, P<0.05) and age (OR=1.04, 95%CI 1.01 - 1.07, P<0.05) were positively associated with thrombotic events. During the in-hospital follow-up, 44.3% of CAP patients and 42.5% of COVID-19 patients died (P>0.05). Receiver operator characteristic (ROC) curve analysis showed that APACHEⅡ score was more accurate in predicting mortality of severe pneumonia, and the area under the ROC curve (AUC) was 0.77 (95%CI 0.70 - 0.84, sensitivity 74.3%, specificity 68.1%), the AUC of the VTE score was 0.61 (95%CI 0.53 - 0.70, Sensitivity 31.4%, specificity 81.7%); the AUC of the creatinine was 0.64 (95%CI 0.56 - 0.73, sensitivity 72.9%, specificity 51.2%). While the Kappa value for kidney disease was 0.409 (P<0.05) presenting moderate consistency. Conclusions The incidence of thromboembolic events and mortality are high in patients with different types of severe pneumonia. Thrombophilia was associated with sex, age, and APTT. APACHEⅡ score, VTE score, and creatinine value were independent risk factors for predicting death from severe pneumonia.
