  • Challenges and countermeasures of thoracic surgery in the epidemic of novel coronavirus pneumonia

    Since December 2019, a novel coronavirus (2019-nCoV, SARS-CoV-2) pneumonia (COVID-19) outbreak has occurred in Wuhan, Hubei Province, and the epidemic situation has continued to spread. Such cases have also been found in other parts of the country. The spread of the novel coronavirus pneumonia epidemic has brought great challenges to the clinical practice of thoracic surgery. Outpatient clinics need to strengthen the differential diagnosis of ground glass opacity and pulmonary plaque shadows. During the epidemic, surgical indications are strictly controlled, and selective surgery is postponed. Patients planning to undergo a limited period of surgery should be quarantined for 2 weeks and have a nucleic acid test when necessary before surgery. For patients who are planning to undergo emergency surgery, nucleic acid testing should be carried out before surgery, and three-level protection should be performed during surgery. Patients who are planning to undergo emergency surgery in the epidemic area should be confirmed with or without novel coronavirus pneumonia before operation, and perform nucleic acid test if necessary. Surgical disinfection and isolation measures should be strictly carried out. Among postoperative patients, cases with new coronavirus infection were actively investigated. For the rescue of patients with novel coronavirus infection, attention needs to be paid to prevention and treatment and related complications, including mechanical ventilation-related pneumothorax or mediastinal emphysema, and injury after tracheal intubation.

  • Chest CT comparison of ground glass opacity-like 2019 novel coronavirus pneumonia and early-stage lung carcinoma

    ObjectiveTo investigate CT image features of ground glass opacity (GGO)-like 2019 novel coronavirus (2019-nCoV, SARS-CoV-2) pneumonia (COVID-19) and early-stage lung carcinoma for control and therapy of this acute severe respiratory disease.MethodsWe retrospectively analyzed the clinical data of 71 GGO-like COVID-19 patients who received therapy in Tongji Hospital of Huazhong University of Science and Technology between January 17th and February 13th, 2020. These 71 GGO-like COVID-19 patients were as a COVID-19 group. And 80 GGO-like early-stage lung carcinoma patients who underwent resection were as a lung carcinoma group. Clinical features such as sex, age, symptoms including fever, cough, fatigue, myalgia and dyspnea, detailed exposure history, confirmatory test (SARS-CoV-2 quantitative RT-PCR) and pathologic diagnosis were analyzed.ResultsSignificantly different symptoms and exposure history between the two groups were detected (P<0.001). More lesions (61 patients at percentage of 85.92%, P<0.001), relative peripheral locations (69 patients at percentage of 97.18%, P<0.001) and larger opacities (65 patients at percentage of 91.55%, P<0.001) were found in chest radiographs of GGO-like COVID-19 compared with GGO-like early-stage lung carcinoma. Similar features appeared in early-stage of COVID-19 and lung carcinoma, while pneumonia developed into more extensive and basal predominant lung consolidation. Coexistence of GGO-like COVID-19 and early-stage lung carcinoma might occur.ConclusionConsidering these similar and unique features of GGO-like COVID-19 and early-stage lung carcinoma, it is necessary to understand short time re-examination of chest radiographs and other diagnostic methods of these two diseases. We believe that the findings reported here are important for diagnosis and control of COVID-19 in China.

  • Novel coronavirus pneumonia (COVID-19) after pulmonary surgery: A case report

    There was a male novel coronavirus (2019-nCoV, SARS-CoV-2) pneumonia (COVID-19) patient after pulmonary surgery at age of 61 years. The patient had no clear history of contact COVID-19 patient before surgery. He developed transient fever on the 4th day after surgery. The body temperature returned to normal on the 5th day after antibiotic adjustment. The patient developed fever and fatigue again on the 6th day after surgery. A chest CT scan revealed postoperative pneumonia. The patient was treated by ganciclovir and moxifloxacin hydrochloride. The patient's temperature gradually decreased on the 7th to 9th days after the operation. CT scan on the 10th day after surgery showed viral pneumonia, so we immediately raised the level of protection. The novel coronavirus nucleic acid test was positive. The patient was immediately transferred to the designated hospital for treatment. The patient was treated by arbidol, moxifloxacin, human immunoglobulin (PH4), ambroxol and other nutritional symptomatic and supportive treatment. The patient's condition is currently stable. Ten people in close contact with the patient developed symptoms, and their CT scans showed viral pneumonia. Six of them were positive in nucleic acid tests, and the others were still under quarantine observation. This shows that it is easy to confuse the imaging manifestations of pneumonia with novel coronavirus pneumonia after lung surgery. We should perform nucleic acid detection as soon as possible in the early diagnosis of CT and reformulate the treatment protocol.

  • A systematic review of SARS-infected pregnant females, newborns, children and adolescents

    ObjectivesTo systematically review the clinical characteristics of pregnant females, newborns, children and adolescents with SARS infection.MethodsThe clinical characteristics of patients with SARS infection were searched using PubMed, EMbase, Web of Science, The Cochrane Library, CNKI, WanFang Data and VIP databases. Descriptive analysis was performed to analyze the clinical characteristics of the patients, clinical manifestations, treatment and prognosis.ResultsA total of 13 studies including 19 pregnant females, 14 newborns, and 81 children and adolescents were identified. The ratio of male to female was 1 to 1.2 in children and adolescents patients aged 56 days to 17.5 years. Children under 12 years old accounted for 58.3% (28/48). Of the child patients, 34.0% (16/47) had close contact with patients with SARS. Fever (93.8%, 76/81) and cough (49.4%, 40/81) were the most common symptoms in children and adolescents with SARS infection, and 17.5% (11/63) occurred with shortness of breath or dyspnea. The positive ratio of nucleic acid detection for SARS-CoV was 9.2% (14/48), and the positive ratio of serum antibody was 92.9% (13/14). Peripheral blood lymphocyte reduction was approximately 65.7% (44/67). Approximately 70.8% (51/72) unilateral and 29.2% (21/72) bilateral lesions were found by thoracic X-ray or CT scan. No child fatalities were reported. As of maternal patients, aged 23 to 44 years, 10 cases (52.6%) were infected during early and middle pregnancy, and 9 cases (47.4%) during late pregnancy. Fever (100.0%, 19/19) and cough (78.9%, 15/19) were the main clinical symptoms, and shortness of breath/dyspnea occurred in 36.8% (7/19) of infected pregnant females. The positive ratio of nucleic acid detection for SARS-CoV was 50.0% (8/16), whereas the positive ratio of serum antibody was 93.3% (14/15). The ratios of thrombocytopenia, lymphopenia, and liver enzymes abnormalities were 38.9% (7/18), 61.1% (11/18) and 50.0% (3/6). All patients were identified for lesions by thoracic X-ray or CT scan examination. Seven cases were severe (36.8%). Five patients were treated with mechanical ventilation (26.3%). Three patients died (15.8%). Four patients were spontaneous abortion (40.0%, 4/10). Nine patients were cesarean sectioned (75.0%, 9/12). Six fetuses (46.2%, 6/13) with fetal distress, 7 cases (53.8%, 7/13) with premature delivery were identified. Three fetuses (23.1%) had intrauterine growth retardation. None of the fourteen newborns was diagnosed as SARS infection.ConclusionsThe clinical symptoms such as fever and cough in children and adolescents with SARS infection are similar to that of adult patients. However, children and adolescents are usually manifested as mild infection without reported death. There is no evidence to support that SARS-CoV could transmit vertically from infected mother to their fetuses.

  • Clinical practice of prevention and treatment of novel coronavirus infection in the medical personnel and surgical patients in the department of thoracic surgery of hospitals in Wuhan

    ObjectiveTo summarize the clinical experience in the prevention and treatment of novel coronavirus (2019-nCoV, SARS-CoV-2) disease (COVID-19) in the department of thoracic surgery of large grade A tertiary hospitals in Wuhan, and to provide feasible clinical practice strategies.MethodsThe clinical data of 41 COVID-19 patients in the department of thoracic surgery of 7 large grade A tertiary hospitals in Wuhan from December 15, 2019 to February 15, 2020 were analyzed retrospectively. There were 20 surgical patients (10 males and 10 females at an average age of 54.35±10.80 years) and 21 medical personnel (7 males and 14 females at an average age of 30.38±6.23 years).ResultsThe main clinical manifestations of COVID-19 patients were fever (70.73%) and cough (53.66%). Normal or reduced peripheral white blood cells and reduced lymphocyte counts were found in the COVID-19 patients, and some patients may have increased C-reactive protein. COVID-19 patients showed limited ground-glass opacities in early chest CT, which was evident in the edge band of lung. The disease could further develop into multiple pulmonary infiltrations, and pulmonary consolidation was found in severe cases. At the time of confirmed diagnosis, most of the medical personnel were ground-glass shadows and unilateral lesions, and even no obvious abnormalities were found in the lungs. The diagnosed COVID-19 patients were transferred to the isolation ward immediately and treated according to the "Diagnosis and Treatment Program of Novel Coronavirus Pneumonia", which was released by the National Health Commission of the People's Republic of China. At the end of follow-up on February 20, 2020, seven surgical patients (35.00%) were discharged and seven (35.00%) were dead, 13 (61.90%) medical personnel were discharged and no death was found.ConclusionsOf all COVID-19 patients in the department of thoracic surgery of hospitals in Wuhan, the proportion of severe degree and mortality in surgical patients are significantly higher than that of the general population, and medical personnel are prone to nosocomial infections. Early oxygen therapy and respiratory support may improve prognosis. During the epidemic period of COVID-19, elective or limited surgery is suggested to be postponed and the indications for emergency operation should be strictly controlled. Emergency operation is suggested to be treated in accordance with tertiary prevention. On the consideration of specialty in the department of thoracic surgery, all people of the ward should be carefully investigated for infection once one case is confirmed with COVID-19. Early detection, isolation, diagnosis, and treatment are the best preventive measures to improve the prognosis of COVID-19.

  • Efficacy of treatments for β-coronaviruses associated respiratory diseases: a systematic review

    ObjectiveTo systematically review the efficacy of treatments for β-coronaviruses.MethodsPubMed, EMbase, Web of Science, The Cochrane Library, SinoMed, CNKI and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) of treatments for β-coronaviruses from inception to June 17th, 2020. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 14.0 software.ResultsA total of 109 studies invoving 23 210 patients were included. The results of the systematic review showed that compared with standard of care, corticosteroids could reduce mortality and increase cure rate for COVID-19. However, chloroquine could decrease cure rate. In severe acute respiratory syndrome (SARS) patients, corticosteroids could decrease the cure rate. In Middle East respiratory syndrome (MERS) patients, ribavirin/interferon/both drugs showed higher mortality.ConclusionsThe currently limited evidence shows that corticosteroids may be effective to COVID-19 patients while having limited effects on SARS patients. Hydroxychloroquine or chloroquine may have negative effects on COVID-19 patients. Ribavirin/interferon may be harmful to MERS patients. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusions.

  • Single-cell meta-analysis of T lymphocytes functional differences in various organs after SARS-CoV-2 infection

    ObjectiveTo explore the functional heterogeneity of T lymphocytes in various organs after SARS-CoV-2 infection. Methods Using the public database GEO data (GSE171668, GSE159812, GSE159556, GSE167747) and the analysis method of single-cell technology, the functional differences of T lymphocytes in various organs of patients after infection with SARS-CoV-2 were analyzed. Results Through single-cell data extraction of 16 livers, 19 hearts,2 spleens, 6 brains, 58 lungs, 21 kidneys and 5 pancreases from SARS-CoV-2 infected patients, invasion genes were relatively highly expressed in T lymphocytes of the lung and pancreas. The lung had a special ability to express the interferon signaling pathway, while the expression of other organs was relatively low; at the same time, the T lymphocytes of the lung also highly expressed fatty acid binding sites. Conclusion After SARS-CoV-2 infection, compared with other organs, the lung has a special interferon-activated signaling pathway and fatty acid binding site.

  • 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.
