Objectives About 12.9-50% patients of SARS (Severe Acute Respiratory Syndrome), require brief mechanical ventilation (MV) to save life. All the reported principles and guidelines for therapy SARS were based on experiences from clinical treatments and facts of inadequacy. Neither prospective randomized controlled trials (RCT) nor other high quality evidences were in dealing with SARS. Our objective is to seek safe and rational non-drugs interventions for patients with severe SARS by retrospectively reviewing clinical studies about MV all over the world, which include clinical guidelines, systematic reviews (SR), Meta-analysis, economic researches and adverse events. Methods To search MEDLINE and Cochrane Library with computer. According to the standards of inclucion or exclusion, the quality of the article which as assessed, and relevant data which were extracted double checked. The Meta-analysis was conducted if the studies had no heterogeneity. Results 14 papers were eligible. Due to the significant heterogeneity between these studies, further Meta-analysis could not be conducted, and the authors’ conclusions were described only. Conclusions The outcome of PPV is better than that of VPV. Patients who underwent PPV had a significantly lower mortality than that of VPV. Of course, the volutrauma should be watched. With low tidal volume and proper PEEP, or decreased FiO2, even permissive hypercapnia, the mortality and length of stay were cut down. Non-invasive mechanical ventilation (NIMV) was effective in treating haemodynamical stable patients, minimizing complications and reducing medical staff infection. Patients with serious dyspnea with PaO2/FiO2lt;200, no profit of NIMV, or couldn’t tolerance hypoxaemia were unlikely to benefit from this technique and needed ventilation with endotracheal intubation. Prone position could improve PaO2/FiO2, NO maybe increased pulmonary perfusion, improved V/Q, and raised oxygenation. Furthermore, Inhaled NO sequentially (SQA) was better than Inhaled NO continuouly (CTA). Some studies implied that practice of protocol-directed weaning from mechanical ventilation implemented by nurses excelled that of traditional physician-directed weaning.
Background 410 Hospital, a hospital in an undeveloped city, identified the first three SARS cases in February, and three more cases in April in Sichuan province. After April 25, it was designated to treat the SARS cases. Objectives This study aims to assess the expenditure for prevention and control of SARS in designated hospital and the impact of SARS on hospital management. Methods With the perspective of SARS designated hospital, a retrospective study was designed. The measures for benefit was healing rate. Medical expenditures of SARS treatment was evaluated, total expenditare were included for assessment in SARS control and management in designated hospital. Sensitivity analysis was applied to explore the range of expenditures when hospital infection rate and healing rate varied. Results All five SARS cases and six suspected cases were cured. The treatment expenditure for SARS confirmed and suspected cases were 7 866 and 4 273 RMB, and their medical expenditures were 14 983.86 and 5 494.92 RMB. Except the expenditure of supporting drugs, no statistical significance was identified in expenditures between confirmed and suspected cases. The total expenditure for designated hospital in control and management of SARS was 1.744 5 million RMB. After designation, the total income of the hospital decreased 33.45 percent compared that before designated. The hospital visits in out-patient and in-patient departments drop 43.62 and 47.33 percent. Conclusions The expenditure of treatment of confirmed and suspected SARS cases were 14 983.86 and 5 490.92 RMB. After designation, the hospital would be great influenced in its management and income.
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.
Objective To investigate the accurateness and rapidity of information on SARS , and to provide evidence for decision-making in the construction of the public health information system of China, including information collection, identification and release. Method SARS related information was systematically collected, from ① databases including Medline, CBMdisc and Cochrane Library; ② official websites including WHO, MOH and CDC; ③ non-governmental websites including Sina, Sohu, Yahoo; ④ eleven Chinese Journals and ⑤ gray literatures, These evidence were graded based on their scientific sense, and were analyzed according to their rapidity of release. Results A total of 11 955 pieces of related information were collected. Non-governmental websites were the agents that released the largest number of information (46.7%). Regarding the scientific sense of evidence, hand searched journal was at the top of the evidence pyramid, and followed by Medline, gray literature, CBMdisc, official and non-governmental websites. Regarding the rapidity, official website achieved the most rapid information release, which was followed by nongovernmental website, journal, and database. 71.8 percent of information from official websites was in Chinese, while 65 percent was from database. Conclusions The SARS information from China has contributed enormously to the global information release. Although the amount and rapidity of the information were satisfied, management and deep processing of information should be improved.
Objective To provide evidence for the establishment and improvement of public health system in China by comparing national public health emergency system of some representative countries.Methods The principle and method of evidence-based science were applied to search and evaluate data from the official websites of China, United States, United Kingdom, Australia and Singapore. The performance of each country’s public health emergency response system in SARS prevention and control, as well as their organization structure and mechanism were compared. The existing problems and corresponding countermeasures were then put forward. Results Public health system showed the best performance was in US, UK and Australia. The responding mechanism of Singapore was highly admired by WHO. The organization structure of China was similar to that of developed countries, but its performance was far lagged behind because of insufficient financial support, poor management and inefficient operational mechanism. Conclusions The public health emergency response system in China needs to be reformed by giving priority to mechanism reinforcement. Different models should be taken into account regarding different regional situations in China.
ObjectiveTo investigate whether novel coronavirus pneumonia (COVID-19) patients complicated with digestive tract symptoms and its influence on digestive system related biochemical indexes.MethodsSixteen novel coronavirus pneumonia patients in our hospital were observed, and their epidemiological data, clinical manifestations and clinical laboratory indicators were analyzed statistically.ResultsThe age of the patients ranged from 5 to 75 years old, and the median age was 46.0 years old. Most of them were male (9 cases, 56.25%), the occurrence of COVID-19 appeared in family aggregation (12 cases, 75.00%). Sixt patients (37.50%) were complicated with basic diseases. The initial symptom involving digestive system accounting for 18.75% (3 cases) of all participants. The main manifestation of a diarrhea in 2 (12.5%) and melena in 1 (6.25%) patients, respectively. Five patients (31.25%) had symptoms of digestive system during the course of the disease, the main symptoms were diarrhea in 3 (18.75%), melena in 1 (6.25%) and loss of appetitein in 5 (31.25%) patients, respectively. The SARS-Cov-2 nucleic acid in the feces of the patients were negative in all patients. In 50.00% of the patients, the SARS-Cov-2 nucleic acid in the feces were negative, but the throat swab/sputum nucleic acid were still positive at the same time or later. Two patients (12.50%) had elevated ALT and 1 patient (6.25%) had elevated AST at the time of admission.ConclusionsPatients with COVID-19 will show symptoms of digestive tract.
Objective To summarize primary clinical data from Xiao Tang Shan Hospital (XTSH) Information System, to provide evidence for clinical data of emerging diseases. Method The primary data were extracted from XTSH information system, which related to demographic and background information, case history, prescriptions, laboratory tests, physical examination, vital sign, surgery, diagnostics and expenditures. The software for data verification was developed by Delphi language program. The information of SARS management was developed by Oracle Developer. Results XTSH information system for SARS management collected 1.09 million pieces of information covering 680 SARS cases. The database was functionally divided into inquiry window, conditional case list window and case details spread window, which provided information of SARS management and shaped a platform for further investigation. Quality control of clinical data was done by the software of SARS Information Real Control.Conclusions XTSH information system collected complete data of SARS management, which made healthcare, research and policy-making on SARS accessible, and made it possible to share resources and train the professionals.
Objective To investigate the clinical effectiveness and adverse event of preventive medicine for severe acute respiratory syndrome (SARS), and provide clinical data for designing prospective clinical trial. Method Retrospective study on medical staffs, that were exposed to SARS patients, was conducted in two main SARS designated hospitals to obtain information such as SARS exposure risk and preventive measures (medical and others). According to the type of preventive medicine, they were assigned to earthworm’s nucleases and protease (ENP) group, interferon group and blank control group respectively. Exposure risk, suspected sub-clinical infection rate and adverse event rate were compared between the three groups. Results Non-medical preventive measures used in each group were consistent, but the exposure intensity to risk factors between groups was statistically different, which biased the evaluation of clinical effectiveness of preventive medicine. The rate of suspected sub-clinical infection in earthworm’s nucleases and protease (ENP) group, interferon group and control group were 4.5%, 4.5%, and 9.9% (Pgt;0.05), respectively; and adverse event rate were 19.6%, 13.6% (Pgt;0.05), and 0%, respectively. Conclusions Suspected sub2clinical infection rate in ENP group, interferon (INF) group were lower than that in control group, which indicated that these two medicines might be effective in preventing SARS. Adverse event rate in ENP group was similar to that of interferon group, and the symptoms were mild in both groups, which was in accordance with the result of in vitro experiments. ENP spray is a kind of biological preparation; further purification may reduce its adverse event rate. However, because there had excessive confounding factors, especially because of the unequal of exposure risk between three groups, the results of this study can only provide insights to design prospective clinical trial in the future.
The Rapid Advice Guidelines (RAGs), prepared in the form of evidence-based guidelines for responding to public health emergencies in a short period, are characterized by their capability to significantly reduce the time for the development of guidelines to the maximum extent while ensuring quality. Therefore, the RAGs are primarily used to guide and respond to public health emergencies. This article will introduce the definition, characteristics, current situation, applicable situation, development methods, advantages and limitations of the RAGs. Our study proposes several suggestions for RAGs developers and researchers to improve development of RAGs in China.
