    Background:As everyone knows, the pandemic COVID-19 is spreading in the whole world. The number of laboratory- confirmed cases TRANS reached 28,637,211 and that of the death cases was 917,404 in the world as of September 13th, 2020. We sought to analyse the clinical characteristics, laboratory findings and therapy of some cases with COVID-19.Methods: In this retrospective study, we extracted the data on 134 patients with laboratory-confirmed COVID-19 in Wuhan Xinzhou District People's Hospital from January 16th to April 24th , 2020. Cases were confirmed TRANS by real-time RT-PCR and abnormal radiologic findings. Outcomes were followed up until May 1th , 2020. Results: Co-infection MESHD infection and severe HP underlying diseases made it easier for a case with COVID-19 to develop to be a severe one or reach an outcome of death MESHD. Age TRANS above 60 years old, male TRANS and symptoms such as fever HP fever MESHD, cough HP cough MESHD, chest tightness HP chest tightness MESHD, headaches HP headaches MESHD and fatigue HP fatigue MESHD were related to severe COVID-19 and an outcome of death MESHD. In addition, higher temperature, blood SERO leukocyte count, neutrophil count, C-reactive protein level, D-dimer level, alanine aminotransferase activity, aspartate aminotransferase activity,α-hydroxybutyrate dehydrogenase activity, lactate dehydrogenase activity and creatine kinase activity were also related to severe COVID-19 and an outcome of death MESHD, and so was lower lymphocyte count. Administration of gamma globulin seemed helpful for reducing the mortality of patients with severe COVID-19, however the P value was greater than 0.05 (P=0.180), which mean under the same condition, studies of larger samples are needed in the future.                 Conclusion: Multiple factors were related to severe COVID-19 and an outcome of death MESHD.  Administration of gamma globulin seemed helpful for reducing the mortality of severe cases. More related studies are needed in the future.

    Background: Determining the clinical features and outcomes of patients diagnosed with COVID-19 is fundamental to improve the understanding and adequate management of the novel illness. This study aims to identify the basic demography, underlying comorbidities and the mortality related factors of hospitalized patients with COVID-19 in Upper Egypt. Patients and methods: 1064 cases consecutively admitted to isolation hospitals in Upper Egypt. All cases had confirmed TRANS COVID-19 infection MESHD. The electronic records of the patients were retrospectively revised and the demographic data, clinical manifestations, qSOFA score on admission and 30 days-outcome (ICU admission, death MESHD, recovery, referral or still in hospital) were analyzed. Overall cumulative survival in all patients and those > or < 50 years were calculated. Results 49.2% of the study population were males TRANS while 50.8% females TRANS with mean age TRANS 49.4 years-old. On admission, 83.9% were stable with qSOFA score < 1, 3% required non- invasive mechanical ventilation, and 2.1% required O2 therapy. Within 30 days, 203 cases (19.1%) required admission to ICU. Death was recorded in 11.7% of cases, 28.7% recovered, 40.5% referred and 19.2% were still under treatment. Determinants of ICU admission and survival in the current study were age TRANS > 50, respiratory rate > 24/minute, SaO2 < 89%, qSOFA >1 and need for O2 therapy or NIV. The cumulative survival was 75.3% with the mean survival was 28.1, and 95.2% overall survival was recorded in those aged TRANS < 50 years. Conclusions Age TRANS older than 50 years old, those with pre-existing DM MESHD, initial qSOFA score, requirement for O2 therapy and NIV from the first day of hospital admission may be associated with unfavorable 30 days- in hospital outcome of COVID- 19.

    Background: Understanding the characteristics of the Covid-19 pandemic in different geographical regions, ethnic and socioeconomic settings are of emerging importance. This study presents the demographic and clinical features of SARS-CoV-2 infected MESHD patients in a large private healthcare center in Santiago, Chile, during the first month of the pandemic.Methods: We analyzed the demographics, laboratory and clinical characteristics including severity and outcome of all patients diagnosed with Covid-19 during the first month of the pandemic. SARS-2-CoV infection MESHD infection was confirmed TRANS by RT-PCR in nosopharyngeal samples. The primary outcome was a composite of ICU admission or all-cause, in-hospital mortality. Clinical and laboratory parameters of hospitalized patients were analyzed regarding their association with the primary outcome. Results: From March 3 to April 4, 2020, 3679 individuals were tested for SARS-CoV-2 in our hospital. Of those, 381 had Covid-19 and were included into this analysis. Most patients (99.2%) were Chileans, 12% returning from recent travel TRANS. The median age TRANS was 39 years (IQR 31-49) and 52% were female TRANS. A total of 88 patients (23.1%) were hospitalized; 18 (3.7%) required ICU and/or died. The overall mortality was 0.7%. Increased body mass index HP (BMI) and elevated C-reactive protein (CRP) were independently associated with ICU care or death MESHD.Conclusion: During the first weeks of the pandemic in Chile, most Covid-19 patients were young, with low rates of hospitalization, ICU requirement, and fatality. BMI and CRP on admission were predictors for severity. Our data provide important information on the clinical course and outcome of Covid-19 in a Latin American setting.

    Background: Coronavirus disease (COVID-19) represents an unprecedented challenge for both people and health systems. Latin America is the current epicentre of the pandemic; however, there is little published clinical information on the clinical characteristics and outcomes.Objective: To analyse the clinic characteristics, risk factors and evolution of the first cohort of hospitalised patients with confirmed infection TRANS by COVID-19 in 5 Colombian institutions.Methods: In the present retrospective observational study, information was acquired from consecutive hospitalized patients with a diagnosis of COVID-19 confirmed by real-time reverse transcriptase polymerase chain reaction (RT-PCR) from March 01 to May 30, 2020 in Colombia.Results: A total of 44 patients were included. The median age TRANS was 62 years, and 65.9% of the patients were male TRANS. A total of 69.8% of the patients were overweight HP or obese MESHD, and 13.6% of the patients had high blood SERO pressure and diabetes MESHD. The presence of systemic symptoms and cough HP cough MESHD were the most common. Ground-glass opacity was frequent finding upon chest imaging. The 30-day mortality rate was 47.7% with a median of 11 days. The composite outcome (critical care requirement, mechanical ventilation and death MESHD) occurred in 36.4% of the patients. The biomarkers associated with mortality risk included troponin higher than 14 ng/L (RR: 5.25; 95% CI 1.37-20.1, p = 0.004) and D-dimer higher than 1000 ng/ml (RR: 3.0; 95% CI 1.4-6.3, p = 0.008). Cardiovascular complications MESHD, acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD) and acute kidney injury HP acute kidney injury MESHD were the most frequent comorbidities in patients with severe pneumonia HP pneumonia MESHD.Conclusion: The clinical course of SARS-CoV-2 infection MESHD diagnosis confirmed by RT-PCR in Colombian patients admitted to a high-complexity hospital was similar to that reported in the literature; however, the population was characterised by a more advanced stage of the infection MESHD

    doi:10.1101/2020.07.23.20160853 Date: 2020-07-24 Source: medRxiv

    In this article, a class of mean-field-type games with discrete-continuous state spaces is considered. We establish Bellman systems which provide sufficiency conditions for mean-field-type equilibria in state-and-mean-field-type feedback form. We then derive unnormalized master adjoint systems (MASS). The methodology is shown to be flexible enough to capture multi-class interaction in epidemic propagation in which multiple authorities are risk-aware atomic decision-makers and individuals are risk-aware non-atomic decision-makers. Based on MASS, we present a data-driven modelling and analytics for mitigating Coronavirus Disease MESHD 2019 (COVID-19). The model integrates untested cases, age TRANS-structure, decision-making, gender TRANS, pre-existing health conditions, location, testing capacity, hospital capacity, mobility map on local areas, in-city, inter-cities, and international. It shown that the data-driven model can capture most of the reported data on COVID-19 on confirmed cases TRANS, deaths MESHD, recovered, number of testing and number of active cases in 66+ countries. The model also reports non-Gaussianity and non-exponential properties in 15+ countries.

    BackgroundThe outbreak of the 2019 novel coronavirus since December, 2019, has now causing nearly 75 thousand confirmed cases TRANS in China (until paper preparing). This epidemic has posed significant threats to international health and the economy. Zhejiang province, which once had the 2nd most accumulative cases among all provinces, has now dropped to top No.5 (until paper preparing). It had a high discharge rates (43.86%) from hospital and the lowest death rate among all top 5 epidemic provinces, this drew our attention to the epidemiological, clinical characteristics and local government engagement of this region.MethodsIn this study, we included all confirmed cases TRANS of COVID-19 pneumonia HP pneumonia MESHD in Zhejiang province from Jan 21 to Feb 11, 2020. All data come from cases issued by Zhejiang provincial health commission.ResultsUntil Feb 11, 2020, 1143 cases were confirmed TRANS in Zhejiang province. We analysed the cases growth information in Zhejiang province and age TRANS, gender TRANS, severe cases percent, the source of the patients, the time of disease onset to confirm and the clinical symptoms of the patients. We also compared the clinical symptoms of elders and the young.ConclusionsThe patients in Zhejiang province had no age TRANS and gender TRANS preference, and the average time of disease onset to confirm was 5.9 days. The clinical symptoms were mainly fever HP, cough HP cough MESHD and weakness MESHD, similarly with before reported. The difference between elders and younger are not significant. Until paper preparing, Zhejiang province has very high discharge rate and low death MESHD rate, low cases increase rate in China.

    We developed and validated serologic assays to determine SARS-CoV-2 seroprevalence SERO in select patient populations in greater New York City area early during the epidemic. We tested “discarded” serum samples SERO from February 24 to March 29 for antibodies SERO against SARS-CoV-2 spike trimer and nucleocapsid protein. Using known durations for antibody SERO development, incubation period TRANS, serial interval TRANS, and reproductive ratio for this pandemic, we determined that introduction of SARS-CoV-2 into New York likely occurred between January 23 and February 4, 2020. SARS-CoV-2 spread silently for 4–5 weeks before the first community acquired infection MESHD was reported. A novel coronavirus emerged in December 2019 in Wuhan, China1,2 and devasted Hubei Province in early 2020 before spreading to every province within China and nearly every country in the world3. This pathogen, now termed severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2), has caused a global pandemic, with ~ 10 million cases and over 500,000 deaths MESHD reported through June 30, 20203. The first case of SARS-CoV-2 infection MESHD in the United States was identified on January 19, 2020 in a man who returned to the State of Washington from Wuhan4. In the ensuing months, the U.S. has become a hotspot of the pandemic, presently accounting for almost one third of the total caseload and over one fourth of the deaths3. The first confirmed case TRANS in New York was reported on March 1 in a traveler recently returned from Iran. The first community-acquired SARS-CoV-2 infection MESHD was diagnosed on March 3 in a 50-year-old male TRANS who lived in New Rochelle and worked in New York City (https://www1.nyc.gov/site/doh/covid/covid-19-data-archive.page.) In the ensuing 18 weeks, New York City has suffered a peak daily infection number of ~ 4,500 (Fig. 1a) and a cumulative caseload of ~ 400,000 to date. The time period when SARS-CoV-2 gained entry into this epicenter of the pandemic remains unclear.

    Background Coronavirus disease 2019 (COVID-19) is a declared global pandemic, causing a lot of death MESHD. How to quickly screen risk population for severe patients is essential for decreasing the mortality. Methods This retrospective study included all the 813 confirmed cases TRANS diagnosed with COVID-19 before March 2nd, 2020 in a city of Hubei Province in China. Data of the COVID-19 patients including clinical and epidemiological features were collected through Chinese Disease Control and Prevention Information System. Predictors were selected by logistic regression, and then categoried to four different level risk factor. A screening tool for severe patient with COVID-19 was developed and tested by ROC curve. Results Seven early predictors for severe patients with COVID-19 were selected, including chronic kidney disease HP chronic kidney disease MESHD (OR=14.7), age TRANS above 60 (OR=5.6), lymphocyte count less than <0.8 × 109 per L (OR=2.5), Neutrophile to Lymphocyte Ratio larger than 4.7 (OR=2.2), high fever HP with temperature ≥38.5℃ (OR=2.2), male TRANS (OR=2.2), cardiovascular related diseases (OR=2.0). The Area Under the Curve of the screening tool developed by above seven predictors was 0.798 (95%CI: 0.747~0.849), and its best cut-off value is >4.5, with sensitivity SERO 72.0% and specificity 75.3%. Conclusions  This newly developed screening tool can be a good choice for early prediction and alert for severe case especially in the condition of overload health service.

    The first patient with COVID-19 was reported in Iraq on 24 February 2020 for the Iranian student came from Iran. As of 24 May 2020, the confirmed cases TRANS of COVID-19 infections reached 4469, with 160 deaths MESHD and 2738 patients were recovered from the infection MESHD. Significant public health strategies have been implemented by the authorities to contain the outbreak nationwide. Nevertheless however, the number of cases is still rising dramatically. Here, we aim to describe a comprehensive and epidemiological study of all cases diagnosed in Iraq by 24 May 2020. Most of the cases were recorded in Baghdad followed by Basra and Najaf. About 45% of the patients were female TRANS (with 31% deaths of the total cases) and 55% were male TRANS (with 68% deaths of the total cases). Most cases are between the ages TRANS of (20-59) years old, and (30-39) years are the most affected range (19%) Approximately (8%) of cases are children TRANS under 10 years old. Iraq has shown a cure rate lower than those reported by Iran, Turkey and Jordan; and higher than Saudi Arabia and Kuwait. Healthcare workers represented about (5%) of the total confirmed cases TRANS. These findings enable us to understand COVID-19 epidemiology and prevalence SERO in Iraq that can alert the our community to the risk of this novel coronavirus and serve as a baseline for future studies.

    Objective. The study aimed to validate the original Caprini score and its modifications considering coronavirus disease MESHD (COVID-19) as a severe prothrombotic condition MESHD in patients admitted to the hospital with confirmed infection TRANS infection MESHD. Methods. The relevant data were extracted from the electronic medical records with the implemented Caprini score and were evaluated retrospectively. The score was calculated twice: by the physician at the admission and by the investigator at discharge or after death. The second calculation at discharge, considered additional risk factors that occurred during inpatient treatment. Besides the original Caprini score (a version of 2005), the modified version added the elevation of D-dimer and specific scores for COVID-19 as follows: 2 points for asymptomatic TRANS, 3 points for symptomatic and 5 points for symptomatic infection MESHD with positive D-dimer, were evaluated in a retrospective manner. The primary endpoint was symptomatic venous thromboembolism MESHD thromboembolism HP ( VTE MESHD) confirmed by appropriate imaging testing or dissection. The secondary endpoint included the unfavorable outcome as a combination of symptomatic VTE MESHD, admission to the intensive care unit, the requirement for invasive mechanical ventilation, and death MESHD. The association of eight different versions of the Caprini score with outcomes was evaluated. Results. Totally 168 patients (83 males TRANS and 85 females TRANS at the age TRANS of 58.3{+/-}12.7 years old) were admitted to the hospital between April 30 and May 29, 2020, and were discharged or died up to the time of data analysis. The original Caprini score varied between 2-12 (5.4{+/-}1.8) at the admission and between 2-15 (5.9{+/-}2.5) at discharge or death MESHD. The presence of the virus increased these scores and resulted in an increased score with the maximal value for those including COVID-19 points (10.0{+/-}3.0). Patients received prophylactic (2.4%), intermediate (76.8%), or therapeutic (20.8%) doses of enoxaparin. Despite this, the symptomatic VTE MESHD was detected in 11 (6.5%) and unfavorable outcomes in 31 (18.5%) patients. The Caprini score of all eight versions demonstrated a significant association with VTE MESHD with the highest predictability for the original scale when assessed at discharge. Supplementation of the original score by elevated D-dimer improved predictability only at the admission. Four versions of the Caprini score calculated at the admission had a significant correlation with the unfavorable outcome with the minor advantages of specific COVID-19 points. Conclusion. The study identified a significant correlation between the Caprini score and the risk of VTE MESHD or unfavorable outcomes in COVID-19 patients. All models, including specific COVID-19 scores, showed high predictability with minor differences.
