Inpatients after COVID-19 infection, especially those admitted to intensive care unit (ICU), may encounter a series of coagulation dysfunction, which may lead to thrombosis, such as pulmonary embolism (PE), deep vein thrombosis (DVT) or arterial thrombosis (AT). Although there are many literatures on the incidence rate, prevention and treatment of venous thromboembolism (VTE) in hospitalized patients with COVID-19 infection, there are few data on the symptomatic and subclinical incidence rate of VTE after COVID-19 infection discharge. Therefore, there are no specific recommendations or guidelines for the prevention of VTE after discharge from hospital due to COVID-19 infection, and the current guidelines are controversial. In this study, we reviewed and summarized the existing literature on the incidence rate, prevention, diagnosis and treatment of venous thromboembolism in patients with COVID-19 infection, in order to provide guidance for VTE prevention in patients with COVID-19 infection after discharge.
With the change of COVID-19, the prevention and control of COVID-19 infection epidemic entered a new stage in December 2022. How to quickly complete the emergency treatment of a large number of patients in a short period of time, and ensure that patients in emergency department can get rapid and effective medical treatment has always been an urgent problem that emergency department need to solve. The Department of Emergency Medicine of West China Hospital of Sichuan University has adopted patient-oriented management measures based on the core idea of the new public management theory, and has achieved remarkable results. Therefore, this article summarizes the workflow and nursing management strategies of the emergency department rescue area of West China Hospital of Sichuan University in dealing with the batch treatment of COVID-19 infected patients, including optimizing and correcting the environment layout of the ward, implementing the “secondary triage” mode in the rescue area, adding an inter-hospital referral platform for critical patients with COVID-19 emergency, building a conventional COVID-19 reserve material repository in the emergency department, setting up a field office for multi-department joint emergency admission service, optimizing emergency transport services for patients with COVID-19, scientific scheduling and reasonable human resource management, and providing humanistic care for employees, in order to provide reference for the management practice of the emergency department.
ObjectiveTo construct a lentiviral vector carrying rat sirt1 gene and observe the expression of sirt1 in retinal ganglion cell (RGC) of rat. MethodsRat sirt1 cDNA was inserted into pLV5 vector. After identification by sequencing analysis and PCR, the recombinant sirt1expressinglentivirus vector was packaged by cotransfecting 293T cells with packaged plasmid.Then pLV5-sirt1 was used to infect the cultured Sprague-Dawley rat RGC cell in vitro.The expressions of sirt1 protein and mRNA in infected rat RGC were detected by quantitative real-time PCR and Western blot. ResultsThe sirt1 expression vector pLV5 was successful constructed and sequence was proved to be correct. The expression of sirt1 protein and mRNA in RGC was significantly increased than that in cells infected with control lentiviruses(P < 0.05). ConclusionWe have successful constructed a sirt1 expression lentivirus vector pLV5-sirt1 and it can increase the expression of sirt1 protein and mRNA in the rat retinal ganglion cells.
In December 2019, an outbreak of pneumonia associated with the coronavirus disease 2019 (COVID-19) occurred in Wuhan, China. The lung imaging finding is like that of the lung cancer immune checkpoint inhibitors (ICI) associated pneumonia. Therefore, we speculated that they may have similar pathogenesis and treatment strategies, which is reviewed in this article in order to provide some reference to timely and effectively reduce the fatality rate of COVID-19.
Objective To investigate the influence of including HIV/AIDS patients on the consolidated fund under the New Cooperative Medical System （NCMS）. Methods Designed questionnaires were used to investigate 24 HIV/AIDS patients and 1155 randomized sample of the population to compare their income, requirement for public health service, expenditure of medical care and to analyze the influence of including HIV/AIDS patients. Results We found the income of HIV/AIDS patients was lower than healthy population in 2003 （722 vs. 2 162 RMB） ; but the requirement （outpatient：2 ：1, inpatient：5 ：1 ）and expenditure of medical care was higher in HIV/AIDS patients. Including HIV/ AIDS patients into NCMS would cause an adverse-effect on consolidated fund. When more than 293 HIV/AIDS patients were included, it would be beyond what the consolidated fund can afford. Conclusions Including HIV/AIDS patients into NCMS can decrease the HIV/AIDS expenditure to some degree. But the government still needs to get involved to share risks and to establish an HIV/AIDS fund to cover that part which NCMS could not afford.
Objective To observe the clinical and multimodel image features in patients of acute macular neuroretinopathy (AMN) associated with COVID-19. MethodsClinical data and multimodal imaging results in 12 patients (24 eyes) of AMN associated with COVID-19 which were diagnosed in our Department of Ophthalmology, The Second Hospital of The Army Medical University ranging from December 2022 to January 2023 were included. All patients were examined by best-corrected visual acuity (BCVA), color fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), visual field tests, high-resolution computed tomography of the lungs and inflammation-related laboratory tests. After diagnosis, patients were reveived methylcobalamin and Ginaton therapy, 6 patients receiced intravenous dripping of dexamethasone. The follow-up time of this study was 4 weeks. ResultsThere were 1 male (2 eyes) and 11 females (22 eyes), with the mean age of (29.00±5.17) years. For all cases, decreased vision presented 1 to 2 days after patients being suffered from several flu-like symptoms of COVID-19. Ten eyes in 5 patients were at the acute phrase of AMN, which the vision decrease occurred 1-5 days after they were diagnosed with COVID-19; 14 eyes in 7 patients were at the progressive stage of AMN, which they were diagnosed with COVID-19 for more than 5 days. The BCVA of patients were 0.02-0.9, in company with one or more central/pericentral scotoma. Fundus ophthalmoscopy revealed reddish-brown lesion around macula, IR imaging demonstrated localized areas of hypo-shape lesions in the macula. For 16 eyes, their OCTA revealed a decreased density of blood flow in the deep layer of retinal capillary plexus, and OCT revealed that high reflex bands existed in the outer nuclear layer (ONL) and outer plexiform layer of the retina at the acute phrase of AMN, in accompany with hypo-reflection in ellipsoid zone (EZ) and interdigitation zone (IZ); for retina at the progressive stage of AMN, ONL became thinner in some cases and the continuation interruption occurred in EZ and IZ. For en-face OCT, high reflex bands with clear edges existed in the ONL and EZ layer of the retina at the acute phrase of AMN, but no high reflex bands existed in the ONL and EZ layers of the retina at the progressive stage of AMN. Instead, hypo-reflection with similar shape occurred in the EZ and IZ layers at the progressive stage of AMN. During treatment, 5 patients at the acute phrase reported a shrinking central scotomas and raised BCVA, otherwise the BCVA of 7 patients at the progressive stage changed slightly. For 10 eyes at the acute phrase of AMN, OCT revealed that the high reflex bands of ONL and OPL missed within 1 week. En-face OCT revealed the hyper-reflection in the ONL and EZ layers of retina in the acute phrase of AMN receded within 1 week, but hypo-reflection of ONL and EZ still presented. ConclusionsFor AMN associated with COVID-19, IR imaging demonstrated localized areas of hypo-shape lesions in the macula. OCT revealed high reflex bands in ONL and OPL of the retina at the acute phrase of AMN, but hypo-reflection of ONL and EZ still presented. The continuation interruption occurred in EZ and IZ at the progressive phrase. En-face OCT revealed hyper-reflection in ONL and EZ of the retina at the acute phrase which receded within 1 week, and hypo-reflection in EZ and IZ of the retina presented at all phrases during AMN progression.
Objective To understand the changing patterns and characteristics of the number of patients hospitalized with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) before, during, and in the post-epidemic period of the COVID-19 pandemic and the Association between acute respiratory infections and hospitalization of patients with AECOPD. Methods A retrospective analysis was conducted to count the patients hospitalized for AECOPD in the Department of Respiratory Medicine of the Third Affiliated Hospital of Chongqing Medical University from July 2017 to June 2024. The pattern of change in the number of AECOPD hospitalizations and the associations with patients with respiratory tract infections in outpatient emergency departments were analyzed. Results During the COVID-19 epidemic, the number of hospitalizations of patients with AECOPD did not increase compared with the pre-epidemic period. Instead, it significantly decreased, especially in the winter and spring peaks (P<0.05). The only exception was a peak AECOPD hospitalization in the summer of 2022. COPD inpatient mortality and non-medical discharge rates tended to increase during the epidemic compared with the pre-epidemic period. Analysis of the curve of change in the number of patients with respiratory infections in our outpatient emergency departments during the same period revealed a downward trend in the number of patients with respiratory infections during the epidemic and an explosive increase in the number of patients with respiratory infections in the post epidemic period, whose average monthly number was more than twice as high as that during the epidemic. Correlation analysis of the number of patients with respiratory infections between AECOPD hospitalizations and outpatient emergency departments showed that there was a good correlation between the two in the pre-epidemic and post-epidemic periods, and the correlation between the two in the post-epidemic period was more significant in particular (r=0.84-0.91, P<0.001).In contrast, there was no significant correlation in 2021 and 2022 during the epidemic (r=0.24 and 0.50, P>0.05 ). The most common respiratory infection pathogens among AECOPD hospitalized patients during the post-epidemic period were influenza virus, COVID-19 virus, and human rhinovirus, respectively. Conclusions The pandemic period of COVID-19 infection did not show an increase in the number of AECOPD hospitalizations but rather a trend towards fewer hospitalizations. Respiratory infections were strongly associated with the number of AECOPD hospitalizations in the pre- and post-pandemic periods, while the correlation between the two was poorer during the pandemic period. Influenza virus was the most important respiratory infection pathogen for AECOPD during the post-epidemic period.
ObjectiveTo systematically review the economy of non-pharmaceutical interventions (NPIs) for COVID-19. MethodsThe Web of Science, PubMed, EMbase, Cochrane Library, INAHTA, CNKI, WanFang Data and SinoMed databases were electronically searched to collect studies on health economic evaluations from 1 January 2020 to 20 August 2022. Then the included materials were reviewed, extracted and data integration analysis were conducted based on inclusion and exclusion criteria. ResultsSeventy-one academic publications were finally included, which contained 25 papers about nucleic acid testing, antigen testing and screening, 5 papers about personal protection, 12 papers about social distancing, quarantine and isolation, 11 papers about regional or national lockdown and 18 papers about multiple NPIs. The results showed that compared with no intervention, nucleic acid testing, antigen testing, screening and personal protection measures were economical. Social distancing, quarantine and isolation were also economical compared with no intervention. However, in low-income countries, movement restriction and factory shutdown may exact a heavy toll on the poorest and most vulnerable. Moreover, compared with a single long-term lockdown, multiple short-term lockdowns could be more economical, but the cost was still huge overall. ConclusionNPIs such as nucleic acid testing, antigen testing, personal protection, social distancing, quarantine, isolation and factory shutdown are economical. Although regional or national lockdown can save lives, it is not suitable for wide use. The researches on specific populations, specific variants (especially Omicron) and in the context of China need to be carried out.
Objective To analyze the clinical characteristics of the Guang’an Omicron epidemic and summarize the management experiences and practices in pandemic prevention and control of major infectious diseases.Methods Retrospective analysis was performed on patients infected with coronavirus disease (COVID-19), afterwards treated and observed in the isolation ward of Guang’an People’s Hospital and the shelter of Guang’an City from May 9 to June 26, 2022. The characteristics of patients at different age stages and the related factors affecting the severity, re-positive and negative conversion was analyzed. Results Finally 1 278 patients were collected, including 508 males and 770 females, with an average age of 41.3±22.6 years. Among them, 1 054 patients were asymptomatic carriers. The overall severe rate was 0.86%, the severe rate of the high-risk group was 3.06%. The median negative conversion time was 10.0 days and re-positive rate was 7.36%. Patients aged＞60 years were 2.589 times more likely to have a longer negative conversion time than those aged≤60 years (95%CI 1.921-3.489, P＜0.001). Conclusion The clinical characteristics of Guang’an COVID-19 epidemic are mainly that the elderly with high risk factors are more likely to develop severe cases, have longer clearance time, and re-positve is more likely to occur.
