Construction of a schistosomiasis transmission risk assessment system in Wuhan City based on analytic hierarchy process / 中国血吸虫病防治杂志

Objective To construct a schistosomiasis transmission risk assessment system in Wuhan City and preliminary evaluate its application effect, so as to promote the rational allocation of schistosomiasis control resources and accelerate the progress towards schistosomiasis elimination. Methods The schistosomiasis risk assessment indicators were collected through referring schistosomiasis surveillance data of Wuhan City from 2014 to 2020, literature review and expert interviews. Indicators within each criterion and sub-criterion were screened using the Delphi method, and a hierarchical structure model was created based on analytic hierarchy process. Quantitative assignment of each indicator was conducted according to relative importance, and the weight and combination weight of each criterion were calculated in each analytic hierarchy framework to create a schistosomiasis transmission risk assessment system, which was used for the schistosomiasis transmission risk assessment in 12 national schistosomiasis surveillance sites in Wuhan City. Results A three-level schistosomiasis transmission risk assessment system was preliminarily constructed, which included a target layer, 5 criterion layers and 21 sub-criterion layers. Of all indicators in the criterion layer, transmission route had the highest weight (0.433), followed by source of Schistosoma japonicum infection (0.294); and among all indicators in the sub-criterion layer, S. japonicum infection in Oncomelania hupensis and sentinel mice had the highest combination weight (0.125), followed by prevalence of S. japonicum infection in humans (0.091) and bovines (0.053), snail control by chemical treatment (0.049), positive rate of inquiry examinations (0.048), allocation of schistosomiasis control professionals (0.045), and areas of submerged snail-infested settings (0.041). Of the 12 national schistosomiasis surveillance sites in Wuhan City, there were 5 sites with weights of > 0.8, 4 sites with weights of 0.6 to 0.8, and 3 sites with weights of < 0.6 in 2020. Conclusion A schistosomiasis transmission risk assessment system has been constructed based on analytic hierarchy process in Wuhan City, which may provide a evidence-based basis for health resource allocation and decision-making for schistosomiasis control.

Objective To evaluate the effectiveness of urban construction projects on Oncomelania snails control in Wuhan City, so as to provide insights into the development of an integrated control strategy for urban schistosomiasis. Methods The data pertaining to the endemic situation of schistosomiasis, schistosomiasis control data, the construction of the Yangtze River Bridge, marshland management and park constructions were collected from Wuhan City from 1990 to 2020. The changes of areas of snail habitats and high-risk settings were compared before and after implementation of these urban construction projects to evaluate the effectiveness of urban construction projects on Oncomelania snails control. Results The number of schistosomiasis cases decreased by 97.35%, and the number of cattle with schistosomiasis decreased by 100% in Wuhan City from 1990 to 2020, with a 41.99% reduction in areas of snail habitats, including 94.97% and 34.40% reductions in snail habitats inside and outside the embankment decreased. During the period from 1990 through 2020, a total of 10 Yangtze River bridges were built in Wuhan City, and areas of snail habitats around the bridges reduced from 11 699.05 hm2 before the bridge building to 8 726.14 hm2 after the building (a 25.41% reduction), while the areas of high-risk settings reduced from 411.69 hm2 before the bridge building to 276.78 hm2 after the building (a 32.77% reduction). Following treatment of three marshlands in Hankou, Hanyang and Wuchang, the areas of snail habitats reduced from 225.80 hm2 before the management to 199.47 hm2 after the management (a 11.66% reduction), and the areas of high-risk settings reduced from 23.14 hm2 before the treatment to 17.73 hm2 after the building (a 23.38% reduction). Following the building of 5 parks in snail-infested settings, the areas of snail habitats reduced from 319.61 hm2 before the construction to 280.80 hm2 after the construction (a 12.14% reduction), and the areas of high-risk settings reduced from 35.00 hm2 before the construction to 27.73 hm2 after the construction (a 20.77% reduction). Conclusion Simultaneous implementation of urban construction projects and schistosomiasis control measures is effective to shrink snail-infested setting and high-risk settings and control the endemic situation of schistosomiasis in endemic foci in Wuhan City.

An acute schistosomiasis case in Wuhan City imported from another province of China in 2020 / 中国血吸虫病防治杂志

An imported case of acute schistosomiasis was reported in Wuhan City in 2020. The case was infected with Schistosoma by contact with the infested water due to playing water in the Yangtze River when working out of Hubei Province. The patient visited four medical institutions and the duration from onset to definitive diagnosis was 20 days. The patient’s low awareness of schistosomiasis prevention and control knowledge and lack of diagnosis and treatment awareness for schistosomiasis among medical institutions were considered as main causes of the development of acute schistosomiasis and progression to severe case. Intensifying schistosomiasis health education among mobile populations and improving the awareness and capability of early diagnosis of schistosomiasis among clinicians are recommended.

SARS-CoV-2: previous coronaviruses, immune response, and development of vaccines / SARS-CoV-2: coronavirus previos, respuesta inmune y desarrollo de vacunas

Abstract Since the emergence of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in China at the end of 2019, when its characteristics were practically unknown, one aspect was evident: its high contagion rate. This high infection rate resulted in the spread of the virus in China, Europe, and, eventually, the rest of the world, including Mexico. At present, around 9 million people are infected, and around 470,000 have died worldwide. In this context, the need to generate protective immunity, and especially the generation of a vaccine that can protect the world population against infection in the shortest possible time, is a challenge that is being addressed in different countries using different strategies in multiple clinical trials. This opinion article will present the evidence of the induction of immune response in some of the viruses of the coronavirus family before COVID-19, such as SARS-CoV and MERS-CoV (Middle East respiratory syndrome coronavirus). The information collected about the induction of an immune response by SARS-CoV-2 will be presented, as well as a description of the vaccine candidates reported to date in the various ongoing clinical trials. Finally, an opinion based on the evidence presented will be issued on the potential success of developing vaccine prototypes.

Resumen Desde el surgimiento del nuevo coronavirus SARS-CoV-2 (coronavirus tipo 2 del síndrome respiratorio agudo severo) en China a finales del año 2019, cuando todavía era desconocido prácticamente en todos los aspectos, una característica era evidente: el alto índice de contagio entre la población. Esto resultó en la expansión del virus en China, Europa y, finalmente, en el resto del mundo, incluyendo México. Actualmente, alrededor de 9 millones de personas están infectadas, y han muerto cerca de 500,000 en todo el mundo. En este contexto, la necesidad de generar inmunidad protectora y, sobre todo, el desarrollo de una vacuna que pueda proteger a la población mundial contra la infección en el menor tiempo posible, es un reto que se está abordando en distintos países utilizando diversas estrategias en múltiples ensayos clínicos. En este artículo de opinión se presentan las evidencias de la inducción de respuesta inmunitaria con algunos de los virus de la familia de coronavirus previos al SARS-CoV-2, como el SARS-CoV (coronavirus del síndrome respiratorio agudo severo) y el MERS-CoV (síndrome respiratorio por coronavirus de Oriente Medio). Además, se presenta lo reportado hasta el momento acerca de la inducción de respuesta inmunitaria por el SARS-CoV-2, así como una descripción de los candidatos a vacunas informados hasta el momento en los distintos ensayos clínicos en curso. Finalmente se emite una opinión, basada en las evidencias presentadas, acerca del éxito potencial de los prototipos de vacunas en desarrollo.

Results: This review includes 5 studies, over all 26 patients who treated CP and following progressions and events. All became clinically better and the antibody titer increased in the patients. Not only that the viral load decreased with a reduction in inflammatory markers Conclusion: These small studies and case series suggest that CP is effective and safety is high for clinical recover and reduction in viral load.

Manifestations of Digestive system in hospitalized patients with novel coronavirus pneumonia in Wuhan, China: a single-center, descriptive study / 中华消化杂志

Objective@#To study the manifestations of digestive system of hospitalized patients with novel coronavirus pneumonia (NCP) in Wuhan, China, and to provide reference for disease control and treatment.@*Methods@#The data of hospitalized patients with NCP in the Sino-French Branch of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology was retrospectively analyzed, which included general information, nucleic acid test, severity degree of disease, incubation period, initial symptoms and manifestations of digestive system. The general information, positive rate of nucleic acid detection, and manifestations of digestive system were compared between critical patients who required non-invasive or invasive assisted ventilation (critical group) and non-critical patients without assisted ventilation (non-critical group). Continuous corrected chi-square test and independent sample median test were performed for statistical analysis.@*Results@#Among the 305 patients there were 146 males (47.9%) and 159 females (52.1%), median age 57 years old. Nucleic acid assay of nasopharynx swab or pharynx swab of 84.1% (228/271) patients were positive. Forty-six patients (15.1%) were in critical group and 259 patients (84.9%) were in non-critical group. The incubation period was one to fifteen days, and the median period was six days. The initial symptoms mainly were fever (81.1%, 163/201), cough (39.3%, 79/201), fatigue (54.7%, 110/201), and loss of appetite (50.2%, 101/201). In one to ten days after the disease onset, 79.1% (159/201) of patients developed gastrointestinal symptoms including nausea (29.4%, 59/201), vomiting (15.9%, 32/201), or abdominal pain (6.0%, 12/201). 49.5% (146/295) of patients had diarrhea, median time was 3.3 days, (3.3±1.6) times per day, and a duration of (4.1±2.5) days. Excluding possible drug-related diarrhea, the incidence of diarrhea still was 22.2%. Only 6.9% (4/58) of patients were found leukocytes or fecal occult blood positive in regular stool test. ALT, AST, or bilirubin increased in 39.1% (119/304) of patients at admission. Patients with ALT or AST ≥ 80 U/L only accounted for 7.9% (24/304) and 6.3% (19/304), respectively. About 2.0% (6/304) of patients also had increased bilirubin level, average level was (37.4 ± 21.1) μmol/L. The median age of critical group was older than that of non-critical group (65.5 years vs. 56 years), at admission the rates of abnormal liver function test abnormal and slightly increased AST (40~80 U/L) of critical group were both higher than those of non-critical group (67.4% (31/46) vs. 34.1% (88/258) and 47.8% (22/46) vs. 21.7% (56/228)), and the differences were statistically significant (x2=5.885, 18.154 and 15.723;all P <0.05). There were no statistically significant differences in the proportion of male (58.7% (27/46) vs. 45.9% (119/259)), the positive rate of nucleic acid detection (94.6% (35/37) vs. 82.5% (193/234)), the percentage of patients with gastrointestinal symptoms (85.0% (17/20) vs. 78.5% (142/181)), the rate of diarrhea (44.7% (17/38)vs. 50.2% (129/257)) and ratio of patients with abnormal bilirubin level (6.5% (3/46) vs. 1.2% (3/258)) (all P>0.05).@*Conclusions@#The manifestation of digestive system of hospitalized NCP patients in Wuhan is significant, the ratio of patients with diarrhea and abnormal aminotransferase level is high. And at admission the rate of patients with abnormal liver function rate of critical group is higher than that of non-critical group, which will provide reference for the prevention and treatment of NCP.

Study on the relationship between the 2019 Novel Coronavirus Disease epidemic in China and population migration from Wuhan / 中华医学科研管理杂志

Objective@#To investigate the relationship between the epidemic of Coronavirus Disease in 2019 (COVID-19) in China and population migration from Wuhan before the city implemented strict migration restrictions.@*Methods@#We collected the cumulative number of confirmed cases with COVID-19 up to January 31, 2020 from the official website of the health administrative departments, and information on population migration out of Wuhan during January 10, 2020 and January 24, 2020, approximately half months prior to the implementation of strict migration restrictions by the city, from Baidu population-migration big data platform. Population migration data were provided for the top 100 cities in the form of percentage values, calculated as the number of migrants from Wuhan into these cities divided by the total number of migrants out of Wuhan during the same period multiplied by 100%. The two-independent sample non-parametric Wilcoxon rank-sum test was used to compare the distribution of cumulative number of cases between the top 100 cities and the remaining 205 non-top 100 cities of China. The relationship between the cumulative number of cases and the percentage of migrants from Wuhan into the top 100 cities were further assessed by Pearson correlation and by multiple linear regression with adjustment for population size, population density, and GDP per capita.@*Results@#The top 100 cities accounted for 91.6% of total migrants out of Wuhan, and the top 14 cities were all in Hubei province. There were a total of 5,869 cases in the top 100 cities, with a median (interquartile range) of 21.5 (12~55) cases, whereas in the 205 non-top 100 cities there were a total of 1,063 cases, with a median (interquartile range) of 4 (2~7) cases. The median cumulative number of cases differed significantly between the two types of cities (P<0.001). Among the top 100 cities, there was a strong correlation between the percentage of migrants from Wuhan and the cumulated number of cases (Pearson correlation coefficient=0.92), and for every 1 percentage point increase in migrants from Wuhan the cumulative number of cases increased by approximately 42 (95%CI, 39 to 45). The number of cumulative number of cases in Wenzhou and Chongqing was detected as potential outliers in regression diagnosis (P<0.001, corresponding standardized residuals were 5.2 and 3.5, respectively), suggesting that the number of cases in these two cities was substantially higher than others with similar amount of migrants from Wuhan.@*Conclusions@#There is a strong positive association between the percentage of migrants from Wuhan and the epidemic status of COVID-19 infections in cities in China.

Practical exploration of the informationization support for prevention and control of the new coronavirus pneumonia with Tongji Hospital as an example / 中华医院管理杂志

December of 2019 witnessed the outbreak of new coronavirus pneumonia in Wuhan city and a few localities. As a designated hospital, Tongji Hospital is designated as a hospital for the diagnosis and treatment of numerous patients of such a disease. Based on the medical cloud platform, the hospital has initiated a regional remote diagnosis center; based on its IT system, the hospital to operate its epidemic prevention and management mechanism, set up the self-service system for patients at the fever clinic, launched its online diagnosis and treatment services, and established a hospital epidemic supervision platform. By strengthening the informational support needed for epidemic prevention and control, the hospital has enhanced its efficiency of epidemic prevention and control, reducing the risk of cross-infection, and ensuring data security. Its experiences offer references for informationization support for other regions and hospitals in China.

Discussion on advantages and disadvantages in prevention and control of emerging infectious disease in Wuhan / 上海预防医学

On the basis of systematic evaluation of 32 provincial capital cities and municipalities in their capacity for preventing and controlling emerging infectious diseases, focus analysis is made on Wuhan in relation to its advantages and disadvantages as follows:There has been a legal basis for epidemic prevention according to law, but it has not translated into effective action.There has been an organizational basis for responding to epidemic, but coordination mechanism has not been effectively established.The management mechanism has been complete, but the division of responsibilities among different departments has not been clear.The monitoring network has been set up, but its role of "predictive warning" has not been played.Insufficiency of public health service delivery was observed owing to lack of financial investment.In cities of China, advantages and disadvantages have been both existent in their capacity to prevent and control of emerging infectious disease.We should be vigilant in this regard. It is imperative to "fill defects, stop leaks and strengthen weakness".There is a Chinese saying:"It is not too late to mend a fold after the sheep have been stolen".

Surgical treatment of primary acute angle-closure glaucoma during COVID-19 disease outbreak in Wuhan / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To summarize the characteristics and treatment of primary acute angle-closure glaucoma during the outbreak of corona virus disease 2019(COVID-19)in Wuhan.<p>METHODS: Five patients(9 eyes)with primary acute angle-closure glaucoma(APACG)of our hospital were enrolled. Eight eyes with sustained high intraocular pressure(IOP)were given phacoemulsification with goniosynechialysis and one eye in preclinical phase was given YAG laser iridectomy from March 3-20, 2020. The preoperative and postoperative IOP, visual acuity, hospitalization days and complications were reviewed and analyzed.<p>RESULTS: Three out of five APACG cases were binocular attack. The onset time was 12-40(25.2±11.82)d. The IOP(48.38±3.22mmHg)of eight eyes decreased significantly after surgeries(12.63±1.68mmHg), the difference was statistically significant(<i>t</i>=12.192, <i>P</i><0.01). The hospitalization time was 2-6(3.8±1.48)d. No COVID-19 infection or severe complications were observed. <p>CONCLUSION:During the epidemic of COVID-19, phacoemulsification with goniosynechialysis is able to reduce IOP of APACG patients who suffered from longer, heavier and binocular attack in the epidemic area effectively and safely. Strict prevention management can effectively ensure the safety of medical staff and patients, but also increase the difficulty of the surgeries meanwhile.

Comparison of epidemiological and clinical characteristics of COVID-19 patients with and without Wuhan exposure / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Background: A novel coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first identified in Wuhan, China, has been rapidly spreading around the world. This study investigates the epidemiological and clinical characteristics of coronavirus disease 2019 (COVID-19) patients in Zhejiang Province who did or did not have a history of Wuhan exposure. Methods: We collected data from medical records of confirmed COVID-19 patients in Zhejiang Province from Jan. 17 to Feb. 7, 2020 and analyzed epidemiological, clinical, and treatment data of those with and without recorded recent exposure in Wuhan. Results: Patients in the control group were older than those in the exposure group ((48.19±16.13) years vs. (43.47±13.12) years, P<0.001), and more were over 65 years old (15.95% control vs. 5.60% exposure, P<0.001). The rate of clustered onset was also significantly higher in the control group than in the exposure group (31.39% vs. 18.66%, P<0.001). The symptom of a sore throat in patients in the exposure group was significantly higher than that in the control group (17.30% vs. 10.89%, P=0.01); however, headache in the exposure group was significantly lower than that in the control group (6.87% vs. 12.15%, P=0.015). More patients in the exposure group had a significantly lower level of lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) than those in the control group. There was no significant difference in any degree of COVID-19 including mild, severe, and critical between the two groups. Conclusions: From the perspective of epidemiological and clinical characteristics, there was no significant difference between COVID-19 patients with and without Wuhan exposure history.

Comparison of the early control process of H7N9 avian influenza in Shanghai and COVID-19 in Wuhan / 上海预防医学

Objective To analyze and estimate the possibility of early control in Shanghai if COVID-19 had begun in Shanghai. Methods Comparison was made in the processes of early control between H7N9 avian influenza in Shanghai in 2013 and COVID-19 in Wuhan in 2019.The early incidence data of Korean COVID-19 was simulated and analyzed to predict whether the medical resources needed in Shanghai were available. Results If it had occurred in Shanghai, it would have taken 22 days from the first case to the government′s emergency response.It was estimated that there would have been 602-763 patients with cumulative onset and onset after incubation period.At least 500 beds of infectious diseases could have been allocated in Shanghai in case of emergency.Through adding beds and resources reallocation in the whole city, patients could have been fully admitted and treated. Conclusion If COVID-19 epidemic had occurred in Shanghai, it′s early control would have been possible though there might have difficulties.

Unprecedented action has been taken to contain the epidemic of coronavirus disease 2019 in China / 中南大学学报(医学版)

The current outbreak of coronavirus disease 2019 (COVID-19) in Wuhan,China,has posed significant threats to international health.By Feb.20,2020,74 576 cases have been confirmed and over 2 118 deaths have reported in the Chinese mainland.Chinese administrations have carried out immediate and prompt measures to stop the spread of the virus.Wuhan city has been shut down since Jan.23,and more than 30 thousand medical workers have been recruited to Hubei province.Two temporary hospitals were constructed to treat severe pneumonia patients,and 15 mobile cabin hospitals were built to treat mild pneumonia cases.Significant improvement regarding the pathogenesis,epidemiology,and diagnosis and therapy for the COVID-19 has been achieved to stop the spread of the epidemics.

Analysis of psychological behavior of college students in Wuhan during the COVID-19 epidemic / 公共卫生与预防医学

Objective To analyze the psychological and behavioral status and influencing factors of college students during the epidemic of COVID-19 in Wuhan. Methods The students from two universities in Wuhan area were selected by stratified cluster sampling, and the self-designed questionnaires were used to conduct the online survey. Statistical analysis was performed using SPSS 22.0. Results Among 3 966 college students surveyed in this study, the proportion of students in Wuhan who thought that their own infection probability was higher than others (11.25%), that their family members were more likely to be infected (15.29%), that they were very worried about their own infection (22.93%), that they were very worried about the infections in the same community (25.27%), and that their own infection risk was higher than others (9.77%), was higher than those of students in other three regions. The total incidence of depression was 27.10%. Multivariate logistic regression analysis showed that the humanities and social science majors living in the city, worrying about the infection of themselves and their families, feeling that they had a higher chance of infection than other, being not optimistic about the epidemic situation, and thinking that the infection had a great impact on people's emotions were the risk factors of depression during the epidemic. Conclusion College students in Wuhan had psychological and behavioral problems during the COVID-19 epidemic. These problems were related to whether they were located in the epidemic area and whether they were worried about infections.
