Since the outbreak of coronavirus disease 2019 (COVID-19), health authorities at all levels have issued many prevention and control schemes, guidelines, and notices, and medical institutions have also formulated hospital-level COVID-19 prevention and control measures accordingly. However, the epidemic prevention and control work can only be done well when the prevention and control measures are effectively implemented. West China Hospital of Sichuan University has adopted the two-level (hospital-level and department-level) supervision. By clarifying the content and frequency of two-level supervision and adopting multiple forms of supervision, a complete supervision system covering the whole hospital has been formed. Through supervision, risk points in prevention and control were identified and continuous improvement was carried out to promote the implementation of prevention and control measures. This paper introduces the application of two-level supervision in COVID-19 prevention and control in West China Hospital of Sichuan University, providing a reference for peers.
This study reports the surgical treatment of a female patient at age of 64 years with novel coronavirus (SARS-CoV-2) latent infection complicated with esophageal foreign body perforation with no significant changes in the lung CT. The patient was confirmed as SARS-CoV-2 infection on the 4th day after surgery and then was transferred into the Department of Infectious Disease in our hospital for treatment. This case has guiding value for the operation of thoracic surgery during the outbreak of novel coronavirus pneumonia.
During the prevention and control of coronavirus disease 2019, West China Hospital of Sichuan University urgently set up 4 medical tents to conduct centralized screening of fever patients, effectively avoiding cross-infection, and at the same time alleviating the pressure on the Department of Emergency Medicine and improving the efficiency of medical treatment for patients with fever. Later, in order to actively respond to China’s severe acute respiratory syndrome coronavirus 2 nucleic acid detection policy, 5 tents were adjusted to carry out the severe acute respiratory syndrome coronavirus 2 nucleic acid detection. This article introduces the function setting, personnel arrangement and protective measures of medical tents in West China Hospital of Sichuan University during the prevention and control of coronavirus disease 2019. It aims to share the experience of urgently setting up medical tents in the prevention and control of coronavirus disease 2019, with a view to provide a reference for the construction of medical tents in other medical institutions.
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.
ObjectiveTo systematically review the efficacy and safety of vaccines for the coronavirus disease 2019 (COVID-19) . Methods The CNKI, VIP, WanFang Data, PubMed, EMbase and Web of Science databases were electronically searched to collect randomized controlled trials (RCTs) on the safety and efficacy of COVID-19 vaccines from their inception to June 30th, 2022. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software and Stata 12.0 software. Results A total of 13 RCTs involving 139 015 subjects were included. The results of meta-analysis showed that the sero-antibody conversion rate (RR=37.883, 95%CI 8.086 to 177.491, P<0.001) and infection prevention rate (RR=1.011, 95%CI 1.006 to 1.017, P<0.001) of the vaccine group were higher than those of the placebo group. The incidence of adverse reactions in the vaccine group was higher than that in the placebo group (OR=1.839, 95%CI 1.165 to 2.903, P=0.009), which mainly included pain, redness, swelling, fever, headache and itching (P<0.05). However, the incidence of serious adverse reactions was not significantly different from that of the placebo group. Conclusion The current evidence shows that the efficacy of the COVID-19 vaccines is high. The most prevalent adverse reactions are mild and moderate, and severe adverse reactions are the same as those of the placebo group. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.
A 49-year-old male patient with compartment syndrome of the right leg caused by acute carbon monoxide poisoning was admitted on December 30, 2019. The patient had a 10-year history of chronic nephritis and began dialysis treatment due to renal failure 1 month ago. Emergency surgical decompression for compartment syndrome was performed after admission. Two weeks later, the patient was diagnosed as the novel coronavirus pneumonia caused by 2019 novel coronavirus (2019-nCoV) infection. Then, the patient was transferred to the isolation ward, where he was given anti-infection, anti-virus, expectorant, heat-clearing and detoxifying drugs, bedside dialysis, and nutrition support symptomatic treatment. After 2 weeks of treatment, the patient is getting better, with no fever, cough, wheezing, and other discomfort. Meanwhile, the sensory and motor functions of right lower limb recovered gradually. This case is rare, severe, and difficult to diagnose and treat. It is the first reported case of novel coronavirus pneumonia after orthopedic surgery.
ObjectiveTo explore and analyze the nutritional risk and dietary intake of patients with coronavirus disease 2019 (COVID-19), and provide data support for nutritional intervention.MethodsCOVID-19 inpatients were investigated in Wuhan Wuchang Hospital and the People’s Hospital of Wuhan University (East Area) from March 9th to 16th, 2020 by Nutrition Risk Screening 2002 (NRS 2002) scale and designed questionnaire. The energy and protein requirements were calculated according to the standard of 30 kcal/(kg·d) and 1.2 g/(kg·d). The nutritional risk, energy and protein intake, body weight and body mass index and their changes in the mild and severe patients were analyzed. The energy and protein intake of the two types of nutritional risk patients was analyzed.ResultsA total of 98 patients with COVID-19 completed the investigation, in whom 46 (46.94%) had nutritional risk, including 32 (39.02%) with mild type and 14 (87.50%) with severe type; and the difference was statistically significant (P<0.001). Compared with the usual condition, the body weight and body mass index of the two types of patients significantly decreased (P<0.01 or P<0.001); the energy and protein intake in mild type patients were significantly higher than those in the severe type patients (P<0.001); compared with the requirement, the protein intake in the two types of patients were significantly lower than the demand, while the energy and protein intake in the mild type patients were significantly lower than the requirement (P<0.05 or P<0.01). The proportion of energy and protein intakes in patients with nutritional risk was significantly higher than that in patients without nutritional risk (P<0.001 or P<0.01); the energy and protein intakes in patients without nutritional risk was significantly higher than that in patients with nutritional risk (P<0.001); the protein intakes in patients with nutritional risk was obviously insufficient (P<0.001); while the energy intake of the patients without nutritional risk was higher than the requirement (P<0.001).ConclusionsCOVID-19 patients has high incidence of nutritional risk which was higher in the severe patients compared with the mild patients. Higher incidence and lower intake of energy and protein are in the severe patients compared with those in the mild patients. Patients with nutritional risk has a higher proportion of energy and protein inadequate intake and lower intake compared with the patients without nutritional risk.
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.
