  • Veno-arterial extracorporeal membrane oxygenation in salvage of cardiogenic shock

    Cardiogenic shock (CS) describes a physiological state of end-organ hypoperfusion characterized by reduced cardiac output in the presence of adequate intravascular volume. Mortality still remains exceptionally high. Veno-arterial extracorporeal membrane oxygenation (VA ECMO) has become the preferred device for short-term hemodynamic support in patients with CS. ECMO provides the highest cardiac output, complete cardiopulmonary support. In addition, the device has portable characteristics, more familiar to medical personnel. VA ECMO provides cardiopulmonary support for patients in profound CS as a bridge to myocardial recovery. This review provides an overview of VA ECMO in salvage of CS, emphasizing the indications, management and further direction.

  • Postoperative management of cardiac and vascular surgery in the period of COVID-19

    ObjectiveTo explore the postoperative characteristics and management experience of patients with coronavirus disease 2019 (COVID-19) undergoing cardiac and vascular surgery. MethodsFrom December 7, 2022 to January 5, 2023, the patients with COVID-19 who were admitted to Cardiovascular Hospital Affiliated to Kunming Medical University and underwent cardiac and vascular surgery were selected. The clinical history, surgical information, postoperative recovery process and treatment plan were analyzed retrospectively. ResultsThere were 18 patients in this group, including 11 (61.1%) males and 7 (38.9%) females, with an average age of 58.1±10.9 years. There were 7 patients of hypertension, 5 patients of diabetes, 3 patients of respiratory diseases, and 2 patient of chronic renal insufficiency. There were 5 (27.8%) patients receiving emergency operations and 13 (72.2%) elective operations. All the 18 patients underwent cardiac and vascular surgery in the period of COVID-19, and the time between the last positive nucleic acid test and the surgery was 1.50 (1.00, 6.25) days. There were 8 patients of pulmonary imaging changes, including 3 patients with chest patch shadow, 3 patients with thickened and disordered lung markings, and 2 patients with exudative changes before operation. Antiviral therapy was not adopted in all patients before operation. Three patients were complicated with viral pneumonia after operation, including 2 patients with high risk factors before operation, who developed into severe pneumonia after operation, and underwent tracheotomy. One patient with thrombus recovered after anticoagulation treatment. Another patient of mild pneumonia recovered after antiviral treatment. The other 15 patients recovered well without major complications. There was no operation-related death in the whole group. One patient died after surgery, with a mortality rate of 5.6%. Conclusion Patients with COVID-19 are at high risk of cardiac and vascular surgery, and patients with high-risk factors may rapidly progress to severe pneumonia. Patients with preoperative lung imaging changes or other basic visceral diseases should consider delaying the operation. Early antiviral combined with immunomodulation treatment for emergency surgery patients may help improve the prognosis.

  • Research progress on the influence and mechanism of SARS-CoV-2 infection on seizure

    At present, there are few studies on patients with epilepsy (PWE) and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), and the results of many studies are inconsistent. SARS-CoV-2 may cause new seizures through a variety of mechanisms, and the susceptibility and mortality of PWE to SARS-CoV-2 remains controversial. During the SARS-CoV-2 pandemic, anxiety, depression and other psychological problems were common among epileptic patients. Clinicians providing telemedicine, telephone chat and video call can effectively reduce the risk of psychological disorders in PWE patients. At the same time, there are many interactions between antiepileptic drugs and various antiviral drugs, which should be carefully considered when using. Considering that the research results are few and many studies contradict each other, PWE and SARS-CoV-2 deserve further exploration in future studies.

  • Expert consensus on prevention and treatment strategies for osteonecrosis of femoral head during the prevention and control of novel coronavirus pneumonia (2020)

    Novel coronavirus pneumonia is a new type of respiratory infectious disease that has rapidly spread in many countries or regions around the world. The World Health Organization (WHO) named it “coronavirus disease 2019 (COVID-19)”. Glucocorticoids (GC) have certain application value in patients with COVID-19, but they need to be used with caution and strict indications and dosage. Application of large doses of GC can also cause osteonecrosis of femoral head (ONFH). On the basis of the latest literature and evidence-based medical evidence on the fight against COVID-19 epidemic and steroid ONFH diagnosis and treatment, the Bone Circulation and Osteonecrosis Professional Committee, Shockwave Medical Specialty Committee of Chinese Research Hospital Association organized Chinese bone necrosis related experts to jointly write this consensus, focusing on the prevention strategy and the protective management measures in the ONFH diagnosis and treatment process during the prevention and control of COVID-19, which can provide reference for hospitals at all levels to carry out early prevention and treatment of ONFH.

  • Study on the correlation between symptoms of coronavirus disease 2019 and frailty

    Objective To investigate the status of frailty in patients with coronavirus disease 2019 (COVID-19), and to analyze the influence of COVID-19 disease on the prevalence of frailty. Methods This study was conducted using a cross-sectional survey method. COVID-19 patients admitted to a centralized isolation point in Guangzhou were selected for an questionnaire survey by “questionnaire star”, between November and December 2022. The questionnaire included the general information questionnaire, Tilburg Frailty Indicator (TFI), the COVID-19 symptom scale and Mental Resilience Scale (RS-11). Multi-model logistic regression analysis was used to explore the influence of COVID-19 on the occurrence of debilitation. Results A total of 667 questionnaires were distributed, of which 594 were valid, with an effective rate of 89.1%. There were 150 patients (25.3%) were frail, 444 patients (74.7%) were non-frail, and 51 patients (8.6%) were newly frail after infected COVID-19. The median TFI score before COVID-19 was 3 (2, 4) points, 16.7% (99/594) were in a weak state. The median TFI score after COVID-19 was 3 (2, 5) points, 25.3% (150/594) were in a weak state. There were statistically significant differences in TFI scores (Z=−6.596, P<0.001) and the incidence of debilitation (χ2=351.648, P<0.001) before and after COVID-19. The results of multivariate logistic regression analysis showed that after controlling disease factors, demographic factors and psychosocial factors, the score of the COVID-19 symptom score was always the influencing factor of COVID-19 patients. The overall change trend of COVID-19 symptom score was statistically significant (P<0.001). Conclusions The COVID-19 symptom score is an important risk factor or predictor of frailty in patients with COVID-19. As the level of COVID-19 symptom score increases, the risk of frailty in COVID-19 patients increases.

  • Research progress of angiotensin converting enzyme 2 co-expression in non-small cell lung cancer and SARS-CoV-2

    Since the first case of corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the end of 2019, the virus has spread rapidly around the world and has become a global public health problem. In the process of this virus epidemic, compared with the general population, cancer patients are considered to be highly susceptible people, especially the lung cancer patients. Some studies have shown that angiotensin converting enzyme 2 (ACE2) may be the pathway for SARS-CoV-2 to infect the host. At the same time, ACE2 is often abnormally expressed in non-small cell lung cancer. Therefore, understanding the respective mechanisms of ACE2 in COVID-19 and non-small cell lung cancer has extremely important reference value for the study of vaccines and therapeutic drugs, and also provides meaningful guidance for the protection of patients with lung cancer during the epidemic. This article reviews the possible invasive mechanism of ACE2 in SARS-CoV-2 and its abnormal expression in non-small cell lung cancer.

  • Infection risk and prevention and control measures of nosocomial infection in urban or regional clustered epidemic

    When a clustered coronavirus disease 2019 epidemic occurs, how to prevent and control hospital infection is a challenge faced by each medical institution. Under the normalization situation, building an effective prevention and control system is the premise and foundation for medical institutions to effectively prevent and control infection when dealing with clustered epidemics. According to the principles of control theory, medical institutions should quickly switch to an emergency state, and effectively deal with the external and internal infection risks brought by clustered epidemics by strengthening source control measures, engineering control measures, management control measures and personal protection measures. This article summarizes the experience of handling clustered outbreaks in medical institutions in the prevention and control of coronavirus disease 2019, and aims to provide a reference for medical institutions to take effective prevention and control measures when dealing with clustered outbreaks.

  • Prevention and treatment of cross infection of novel coronavirus pneumonia in thoracic surgery ward

    ObjectiveBy summarizing the clinical characteristics of perioperative patients with cross infection of novel coronavirus in thoracic surgery ward, to guide the prevention and treatment of nosocomial infection during the anti-epidemic period.MethodsThe clinical data of 451 patients with chest diseases in the Department of Thoracic Surgery of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from January 1st to 24th, 2020 were analyzed and followed up. There were 245 surgical patients and 206 non-surgical patients.ResultsIn the department, 7 patients (7/451, 1.55%) were infected with the novel coronavirus and all of them were surgical patients, whose preoperative imaging data did not reveal the imaging changes of novel coronavirus. There were 5 males and 2 females, aged 56 to 68 years. The patients with old age, smoking, surgery, coronary heart disease, chronic liver disease and tumor history were more susceptible to infection. From the spatial distribution of patient beds, it was found that the distance among infected patients was greater than 1 m, and no cross infection was found in the other patients of the same ward. During follow-up, two family members of noninfected patients were found to be infected one week after discharge. However, there was no overlap of spatiotemporal distribution between the family members and the infected patients during the hospitalization period.ConclusionThe novel coronavirus pneumonia rate in the department of thoracic surgery is low, which may be opportunistic infection. At the same time, a good control and prevention of epidemic disease can reduce the occurrence of cross infection in the department of thoracic surgery.

  • Thinking about hot issues in the diagnosis and treatment of novel coronavirus pneumonia

    At the end of December 2019, some hospitals in Wuhan, Hubei, China found unexplained pneumonia cases one after another. On January 12, 2020, World Health Organization officially named the new coronavirus that caused the outbreak as “2019 new coronavirus”. The National Health Committee of China has organized experts to compile a “pneumonia diagnosis and treatment program for new coronavirus infection” to guide the prevention, control, diagnosis and treatment of the disease. However, due to the limited knowledge of the disease, there are still many problems to be solved in the diagnosis and treatment of the disease. We reviewed the researches on coronavirus infections related to severe acute respiratory syndrome and Middle East respiratory syndrome, combined with our own experience in diagnosis and treatment, and proposed some thoughts on several unclear hot issues such as the mode of disease transmission, the incubation period, the practical application of diagnostic standards, and the choice of treatment drugs in the diagnosis and treatment plan.

  • Analysis on the formation of antibodies to COVID-19 inactivated vaccine for critical care workers in Sichuan Province

    ObjectiveTo investigate the antibody concentration and immune status of intensive care medical staff after vaccination against COVID-19. Methods From October 1, 2021 to February 28, 2022, the serial numbers of 47 hospitals were randomly selected by cluster stratified random sampling method. Blood samples were collected from 192 medical staff in intensive care department who had received inactivated novel coronavirus vaccine in 7 hospitals. The antibody concentration was determined by chemiluminescence method to find the antibody rule. Logistic regression analysis was used to determine the related factors affecting the production of antibodies. ResultsTotal antibody concentration of 192 blood samples was 23.25 (5.09, 270.22), IgG concentration was 0.94 (0.15, 4.48), IgM concentration was 0.05 (0.03, 0.12). Logistic regression analysis showed that the total antibody concentration might be related to gender and age, and the IgG concentration was significantly related to whether the third injection was administered. One hundred and twenty-seven people received 2 doses of inactivated vaccine, and the positive rate of IgG was the highest within 1 to 2 months, and decreased significantly after 3 months. The positive rate of IgG antibody was 95.4% within 60 days after receiving 3 doses of vaccine, 70% within 1 month after receiving the third dose of vaccine, and 100.0% within 1 to 2 months (P<0.05). The total antibody positive rate was 96.3% in people aged 17 to 35 years and 73.3% in people aged 36 to 58 years, showing statistical difference (P<0.05). The total antibody production rate of those who received the third dose of vaccine was 100.0%, and no severe case of COVID-19 occurred during the sampling period. Conclusions After the first, second, and third doses of COVID-19 vaccine, the total antibody concentration of the virus gradually increases to 100.0%, indicating initial immunity. However, the antibody concentration decreased gradually after 3 months of inoculation. The concentration of IgG in women is higher than that in men, and the concentration of antibody in young people is higher than that in middle-aged and elderly people during the same period.
