This project paper is to give a prediction for the future of other viral pandemics and to provide recommendations for preparing therapies that could help in the success of effective treatments and benefits for patients in life-threatening situations. The theory of prediction was proposed by Huu S. TIEU on March 25, 2019, and he hypothesized that any malfunctioning cell in the body could have a damaging effect. This paper discusses the prediction that Localized Oxygen Deprivation could be a contributing factor for a future epidemic or other viral pandemics that could affect body function. This paper is based on opinion and does not have sufficient evidence to support the claims made. Therefore, further in-depth study is needed to prove the findings. The author cites Hypoxia to support his idea, but he is not claiming that Hypoxia-Inducible Factor (HIF) has worked on his predictions. The author also tested a theory using cow blood curd for body function, but this test was not a structured test and the findings were not supported by other evidence. To further prove the idea or theory, further study into the subject should be conducted. 展开更多

To detect the presence of endothelial injury in patients with severe acute respiratory syndrome (SARS) via enhanced levels of tissue-type plasminogen activator (t-PA) and soluble thrombomodulin (sTM). Methods Case patients were from Xuanwu Hospital (Capital University of Medical Sciences, Beijing, China), and all of them met clinical criteria for SARS. Healthy controls were some of the hospital employees. Endothelial injury bio-markers tPA and sTM were detected by commercial ELISA-methods. Results Classic plasma markers of endothelial injury, tPA and sTM significantly elevated in SARS patients in comparison to controls [t-PA: 1.48±0.16 nmol/L versus 0.25±0.03 nmol/L (P〈0.0001), and sTM: 0.26±0.06 nmol/L versus 0.14±0.02 nmol/L (P〈0.05)]. The only patient who died had extremely high levels of these endothelial injury markers (t-PA: 2.77 nmol/L and sTM: 1.01 nmol/L). The likelihood ratio analysis indicated the excellent discriminating power for SARS at the optimal cut-point of 0.49 nmol/L for tPA and 0.20 nmol/L for sTM, respectively. Significant numerical correlations were found among these endothelial injury markers in SARS patients. The numerical coefficient of correlation Pearson r between t-PA and sTM was 0.5867 (P〈0.05). Conclusion Increased plasma concentrations of tPA and sTM in patients with SARS suggest the possibility of endothelial injury. SARS patients might need anticoagulant therapy or fibrinolytic therapy in order to reverse intraalveolar coagulation, microthrombi formation, alveolar and interstitial fibrin deposition. It may not only provide a useful treatment and prognostic index but also allow a further understanding of the pathological condition of the disease. 展开更多

In order to analyze the immune response to severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV), immunoinformatics and computational analyses were performed to study the immunological characters of SARS-CoV. According to the results of immunoinformatics analysis, the obvious variation of HLA-A2 associated T cell epitopes between SARS vires and HCoV-229E was found as follows: (1) Disappearance of HIA-A2 binding site; (2) variation sequence on the HLA-A2 associated epitope; (3) emergence of a new HLA-A2 associated epitope. The immunoinfomatics results were evidenced by T2 cell binding assay, ELISPOT and DimerX staining. In conclusion, immunoinformatics is a useful method to analyze the immunological character of a new finding infectious pathogen, like SARS-CoV. These findings of immunoinformatics are confirmed by lab and clinical experiments. In this case, immunoinformatics seems a very useful tool in the study of immune response and the evaluation of vaccine in infectious diseases, such as SARS. 展开更多

Objective To describe epidemiologic features of an outbreak of severe acute respiratory syndrome (SARS) in Dongcheng District, Beijing occurred in a period between March and May 2003. Methods Data of SARS cases notified from Dongcheng District Center for Disease Control and Prevention (CDC )and supplemented by other channels were collected. Clinicians and officials of local hospitals were interviewed in groups and medical records of fatal cases of SARS were reviewed to verify the diagnosis. Stored serum specimens of the patients were detected for IgG antibody against SARS Co-V by enzyme-linked immunosorbent assay (ELISA). All the data were input into dataset files by Microsoft Excel-2000 software and analyzed with SPSS version 10.0 software. Results Outbreak of SARS in Dongcheng District started on March 14, 2003 with a peak in mid- and late April, and dropped in early May. A total of 572 reported cases were collected during this period in Dongcheng District, Beijing, and 99 of them were excluded from SARS, because of diagnosis of common cold, regular pneumonia, measles and rubella, etc. Actually, 473 SARS cases, which included 390 (82.5%) probable cases and 83 (17.5%) suspect cases, were analyzed. About 90% of the probable cases were positive for IgG antibody. Attack rate of SARS in permanent residents of Dongcheng District was 28.3 per 100 000. Forty-one of them died, with a case-fatality rate of 8.7%. Persons were all susceptible to infection of SARS Co-V, with the highest proportion at ages of 20-50 years, which accounted for 68.7% of the total cases. Average age of the patients at their onset was 40.7 years. No gender difference in SARS cases was found. Number of SARS cases in health-care workers (HCWs) accounted for 18.0% and that in retired workers accounted for 15.4% of the total cases. Cases occurred in all 10 sub-districts of Dongcheng, with the highest in Beixinqiao and Andingmen Sub-districts. Totally, 230 of the 572 notified cases (40.2%) were hospitalized at local hospitals under the jurisdiction of Dongcheng District. Eighteen of 85 cases of SARS occurred in HCWs of local hospitals, accounting for 4.5% of the total number of HCWs working at wards caring for SARS patients or fever clinics. There were 34.7% of SARS cases without any histories of contact before the onset of the disease. Familial aggregation phenomena were observed in 41.8% of the cases and 18.1% of households. And 7.4% (attack rate ) of those exposed to SARS cases suffered from the illness during the periods of quarantine. Conclusions SARS appeared to be infectious in origin and caused outbreak in Dongcheng District, Beijing introduced by an imported case traveling from Hong Kong in a period between March and May 2003. People are all susceptible to infection of SARS Co-V, which mainly threatens the young adults and the middle-aged, as well as HCWs and the retired workers. The main mode of transmission is direct exposure to SARS patients in a near distance at hospitals or families via droplets spread. Prevention and control of SARS should be focused on early isolation of patients and quarantine for close contacts. Current available measures to prevent and control SARS are proved to be effective. 展开更多

Objective: To explore the changes of tongue pictures in the developing process of disease in patients with severe acute respiratory syndrome (SARS), and to compare the tongue pictures of SARS patients with those of suspected SARS patients. Methods: Materials of tongue picture were dynamically collected from 34 SARS patients and 35 suspected SARS patients, and the difference and similarity between them were analyzed. Meanwhile, the changes in clinic symptoms and tongue picture after integrative medicinal treatment were observed. Results: Characteristics of tongue picture in SARS patients were changed along with the progress of the disease, showing that there existed a tendency of the pathogen invading from exterior to interior, from surface to the deep. Also the tongue pictures were varied due to the coexistence of dampness pathogen; the time of the early stage was generally 1 - 1.5 days, shorter than that of other stages. While in the patients with suspected SARS, the tongue picture was mostly red with thin white or yellow coating, comparatively steady and showing no obvious change along with the development of the disease. Conclusion: Observing the tongue picture and its changes in different stages can be helpful to understanding the property of pathogenic evil and its developing rules, thus offering a basis for clinical treatment. 展开更多

Objective To summarize lessons learned from an outbreak of severe acute respiratory syndrome (SARS) in China during the spring of 2004. Methods Data of SARS cases were officially reported by Beijing Municipal Center for Disease Control and Prevention (BCDC) and Anhui Provincial Center for Disease Control and Prevention (APCDC) and results of epidemiological investigations were collected and analyzed. Results Three generations of 11 cases of SARS were identified during the outbreak, Initial two cases were most likely to be infected in Diarrhea Virus Laboratory of National Institute of Virology, China Centers for Disease Control and Prevention and main mode of transmission was direct contact with SARS patients, Delay in detecting initial case resulted in spread of the illness at hospitals and communities with two generations of secondary cases, Conclusions SARS outbreak in 2004 has yielded following lessons for public health globally. (1) Lab bio-safety programs should be made and should be strictly abided by, Studies in highly pathogenic viruses such as SARS coronavirus should be utmost cautious, (2) Management systems of occupational exposure to virus and disease surveillance need to be strengthened to take all risk factors into account so as to detect potential patients with infectious disease as early as possible. 展开更多

To evaluate the role of murine fibrinogen like protein 2 (mfgl2) /fibroleukin in lung impairment in Severe acute respiratory syndrome (SARS), a murine SARS model induced by Murine hepatitis virus strain 3 (MHV-3) through trachea was established. Impressively, all the animals developed interstitial pneumonia with extensive hyaline membranes formation within alveoli, and presence of micro-vascular thrombosis in the pulmonary vessels. MHV-3 nucleocapsid gene transcripts were identified in multiple organs including lungs, spleen etc. As a representative proinflammatory gene, mfgl2 prothrombinase expression was evident in terminal and respiratory bronchioles, alveolar epithelia and infiltrated cells in the lungs associated with fibrin deposition and micro-vascular thrombosis. In summary, the established murine SARS model could mimic the pathologic characteristics of lungs in patients with SARS. Besides the physical damages due to virus replication in organs, the up-regulation of novel gene mfgl2 in lungs may play a vital role in the development of SARS associated lung damage. 展开更多

The new coronavirus (SARS-CoV-2) broke out in Wuhan in China in December 2019, causing severe pneumonia and deaths, soon in March 2020, it reached pandemic level, affecting several countries including Brazil. The disease was named COVID-19, with characteristics of most infected having mild and moderate symptoms and a part severe symptom. The disease has already reached 158 ethnic groups, which have high vulnerability and limited access to health services. The objective is to investigate the clinical and spatial characteristics of Severe Acute Respiratory Syndrome of COVID-19 in the indigenous peoples of Brazil. It is an epidemiological, cross-sectional, analytical ecological study, based on data from the OpenDataSUS platform from 01/01/2020 to 31/08/2020. Profile variables, signs and symptoms and risk factors/comorbidities. The data were analyzed by Bioestat 5.3. There were 1,207 cases and 470 deaths. Profile: male gender (59.48%) means age 53 years. Signs and symptoms: fever (74.23%), cough (77.71%), sore throat (35.62%), dyspnea (69.34%), respiratory discomfort (62.80%), O<sub>2</sub> saturation < 95% (56.42%);and associated with mortality: dyspnea (80.0%) and O<sub>2</sub> saturation < 95% (69.36%). Risk factors and comorbidities (45.89%) were associated with deaths (54.04%). About comorbidities, chronic cardiovascular diseases represented (18.97%) and Diabetes Mellitus (18.97%), and associated with deaths: Chronic Cardiovascular Disease (24.46%). Being admitted to the ICU has a risk of death in (OR-3.96- < 0.0001-CI-2913/5383) followed by not being vaccinated against influenza (OR-1.85- < 0.0001-CI-1358/2528). The public and health policies of Brazil should be directed to control the dissemination of COVID-19 in this population, that COVID-19 evolves in the same intensity, however, the indigenous have vulnerabilities that can increase the impact of the pandemic in this population. 展开更多
