    OBJECTIVE: To conduct a systematic review and meta-analysis to assess the prevalence SERO of various clinical symptoms and laboratory findings of COVID-19 in children TRANS. METHODS: PubMed, MEDLINE, and SCOPUS databases were searched to include studies conducted between January 1, 2020, and July 15, 2020 which reported data about clinical characteristics and laboratory findings in laboratory-confirmed diagnosis of COVID-19 in pediatric patients. Random effects meta-analysis using generalized linear mixed models was used to estimate the pooled prevalence SERO. RESULTS: The most prevalent symptom of COVID-19 in children TRANS was 46.17% (95%CI 39.18-53.33%), followed by cough HP (40.15%, 95%CI 34.56-46.02%). Less common symptoms were found to be dyspnea HP dyspnea MESHD, vomiting HP vomiting MESHD, nasal congestion/ rhinorrhea HP rhinorrhea MESHD, diarrhea HP diarrhea MESHD, sore throat/pharyngeal congestion, headache HP headache MESHD, and fatigue HP fatigue MESHD. The prevalence SERO of asymptomatic TRANS children TRANS was 17.19% (95%CI 11.02-25.82%). The most prevalent laboratory findings in COVID-19 children TRANS were elevated Creatinine Kinase (26.86%, 95%CI 16.15-41.19%) and neutropenia HP neutropenia MESHD (25.76%, 95%CI 13.96-42.58%). These were followed by elevated LDH, thrombocytosis HP thrombocytosis MESHD, lymphocytosis HP lymphocytosis MESHD, neutrophilia HP, elevated D Dimer, Elevated CRP, elevated ESR, leukocytosis HP leukocytosis MESHD, elevated AST and leukopenia HP leukopenia MESHD. There was a low prevalence SERO of elevated ALT and lymphopenia HP lymphopenia MESHD in children TRANS with COVID- 19. CONCLUSIONS AND RELEVANCE: This study provides estimates of the pooled prevalence SERO of various symptoms and laboratory findings of COVID-19 in the pediatric population.

    (1) Background: This study aims to identify different clinical phenotypes in COVID-19 88 pneumonia HP pneumonia MESHD using cluster analysis and to assess the prognostic impact among identified clusters in 89 such patients. (2) Methods: Cluster analysis including 11 phenotypic variables was performed in a 90 large cohort of 12,066 COVID-19 patients, collected and followed-up from March 1, to July 31, 2020, 91 from the nationwide Spanish SEMI-COVID-19 Registry. (3) Results: Of the total of 12,066 patients 92 included in the study, most were males TRANS (7,052, 58.5%) and Caucasian (10,635, 89.5%), with a mean 93 age TRANS at diagnosis of 67 years (SD 16). The main pre-admission comorbidities were arterial 94 hypertension HP hypertension MESHD (6,030, 50%), hyperlipidemia HP hyperlipidemia MESHD (4,741, 39.4%) and diabetes mellitus HP diabetes mellitus MESHD (2,309, 19.2%). The 95 average number of days from COVID-19 symptom onset TRANS to hospital admission was 6.7 days (SD 7). 96 The triad of fever HP fever MESHD, cough HP cough MESHD, and dyspnea HP dyspnea MESHD was present almost uniformly in all 4 clinical phenotypes 97 identified by clustering. Cluster C1 (8,737 patients, 72.4%) was the largest, and comprised patients 98 with the triad alone. Cluster C2 (1,196 patients, 9.9%) also presented with ageusia and anosmia MESHD anosmia HP; 99 cluster C3 (880 patients, 7.3%) also had arthromyalgia, headache HP headache MESHD, and sore throat; and cluster C4 100 (1,253 patients, 10.4%) also manifested with diarrhea HP diarrhea MESHD, vomiting HP vomiting MESHD, and abdominal pain HP abdominal pain MESHD. Compared to 101 each other, cluster C1 presented the highest in-hospital mortality (24.1% vs. 4.3% vs. 14.7% vs. 102 18.6%; p<0.001). The multivariate study identified phenotypic clusters as an independent factor for 103 in-hospital death. (4) Conclusion: The present study identified 4 phenotypic clusters in patients with 104 COVID-19 pneumonia HP pneumonia MESHD, which predicted the in-hospital prognosis of clinical outcomes.

    Objective To investigate the epidemiological characteristics, clinical features, treatment and short-term prognosis of SARS-CoV-2 infection MESHD in children TRANS.Methods A retrospective analysis was conducted in children TRANS with SARS-CoV-2 admitted to twelve hospitals in eight cities in Hunan province, China, from January 26, 2020 to June 30, 2020.Results A total of 48 children were enrolled in this study. 11 cases (23%) were asymptomatic TRANS, 15 cases (31%) were mild, 20 cases (42%) were moderate, and 2 cases (4%) were severe. No children TRANS were critical requiring intensive care. The most common symptom was fever HP fever MESHD (42%), cough HP (40%), fatigue MESHD (17%) and diarrhea HP diarrhea MESHD (10%). The total peripheral blood SERO leukocytes count decreased in two case (4%), Lymphocytopenia MESHD was present in 5 cases (10%). There were abnormal chest CT changes in 22 children (46%), including 15 (68%) with patchy ground glass opacity. In addition to supportive treatment, 41 children TRANS (85%) received antiviral therapy, 11 patients and (23%) were treated with antibiotics, 2 children TRANS (4%) were treated with methylprednisolone and IVIG. There was no death occurred.Conclusions Most children TRANS with SARS CoV-2 infection MESHD in Hunan province were asymptomatic TRANS, mild or moderate. Severe cases are rare. Close family contact was the main route of infection MESHD. The younger the age TRANS, the less obvious symptoms for children TRANS might be. Epidemiological history, nucleic acid test and chest imaging were important tools for the diagnosis in children TRANS.

    The novel coronavirus outbreak of SARS-CoV-2 first began in Wuhan, China in December, 2019. The most striking manifestation is atypical pneumonia HP pneumonia MESHD and respiratory complications MESHD, however various neurological manifestations are now well recognized. Currently, there have been a very few case reports in regards to COVID-19 in patients with known history of myasthenia gravis MESHD. Myasthenia gravis MESHD ( MG MESHD) causes muscle weakness HP muscle weakness MESHD, especially respiratory muscles in high-risk COVID-19 patients that can lead to severe respiratory compromise. There are few reported cases of severe myasthenia crisis MESHD following COVID-19, likely due to the involvement of the respiratory apparatus and from use of immunosuppressive medication. We report a first case MG MESHD developing secondary to COVID-19 infection MESHD in a 65-year-old woman. Two weeks prior to hospitalization, the patient suffered from cough HP, fever HP fever MESHD, diarrhea HP diarrhea MESHD and was found to be positive for COVID-19 via nasopharyngeal RT-PCR swab test. The electrodiagnostic test showed decremental response over more than 10% on repetitive nerve stimulation test of orbicularis oculi. She tested positive for antibodies SERO against Acetylcholine receptor (AchR).COVID-19 is known to cause release of inflammatory cytokines leading to immune-mediated damage. MG MESHD is an immune-mediated disorder caused due to molecular mimicry and autoantibodies against the neuromuscular junction.

    Background: COVID-19 is a globally emerging infectious disease MESHD. As the global epidemic continues to spread, the risk of COVID-19 transmission TRANS and diffusion in the world will also remain. Currently, several studies describing its clinical characteristics have focused on the initial outbreak, but rarely to the later stage. Here we described clinical characteristics, risk factors for disease severity and in-hospital outcome in patients with COVID-19 pneumonia HP pneumonia MESHD from Wuhan. Methods: Patients with COVID-19 pneumonia HP pneumonia MESHD admitted to Cancer Center, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from February 13 to March 8, 2020, were retrospectively enrolled. Multivariable logistic regression analysis was used to identify risk factors for disease severity and in-hospital outcome and establish predictive models. Receiver operating characteristic (ROC) curve was used to assess the predictive value of above models.Results: 106 (61.3%) of the patients were female TRANS. The mean age TRANS of study populations was 62.0 years, of whom 73 (42.2%) had underlying comorbidities mainly including hypertension HP hypertension MESHD (24.9%). The most common symptoms on admission were fever HP fever MESHD (67.6%) and cough HP (60.1%), digestive symptoms (22.0%) was also very common. Older age TRANS (OR: 3.420; 95%Cl: 1.415-8.266; P=0.006), diarrhea HP diarrhea MESHD (OR: 0.143; 95%Cl: 0.033-0.611; P=0.009) and lymphopenia HP lymphopenia MESHD (OR: 4.769; 95%Cl: 2.019-11.266; P=0.000) were associated with severe illness on admission; the area under the ROC curve (AUC) of predictive model were 0.860 (95%CI: 0.802-0.918; P=0.000). Older age TRANS (OR: 0.309; 95%Cl: 0.142-0.674; P=0.003), leucopenia (OR: 0.165; 95%Cl: 0.034-0.793; P=0.025), increased lactic dehydrogenase (OR: 0.257; 95%Cl: 0.100-0.659; P=0.005) and interleukins-6 levels (OR: 0.294; 95%Cl: 0.099-0.872; P=0.027) were associated with poor in-hospital outcome; AUC of predictive model were 0.752 (95%CI: 0.681-0.824; P=0.000).Conclusion: Older patients with diarrhea HP diarrhea MESHD and lymphopenia HP lymphopenia MESHD need early identification and timely intervention to prevent the progression to severe COVID-19 pneumonia HP pneumonia MESHD. However, older patients with leucopenia, increased lactic dehydrogenase and interleukins-6 levels are at a high risk for poor in-hospital outcome.Trial registration: ChiCTR2000029549

    Case identification is an ongoing issue for the COVID-19 epidemic, in particular for outpatient care where physicians must decide which patients to prioritise for further testing. This paper reports tools to classify patients based on symptom profiles based on 236 SARS-CoV-2 positive cases and 564 controls, accounting for the time course of illness at point of assessment. Clinical differentiators of cases and controls were used to derive model-based risk scores. Significant symptoms included abdominal pain HP abdominal pain MESHD, cough HP, diarrhea HP diarrhea MESHD, fever HP fever MESHD, headache HP headache MESHD, muscle ache MESHD, runny nose, sore throat, temperature between 37.5{degrees}C and 37.9{degrees}C, and temperature above 38{degrees}C, but their importance varied by day of illness at assessment. With a high percentile threshold for specificity at 0.95, the baseline model had reasonable sensitivity SERO at 0.67. To further evaluate accuracy of model predictions, we firstly used leave-one-out cross-validation, which confirmed high classification accuracy with an area under the receiver operating characteristic curve of 0.92. For the baseline model, sensitivity SERO decreased to 0.56. Secondly, in a separate ongoing prospective study of 237 COVID-19 and 346 primary care patients presenting with symptoms of acute respiratory infection MESHD, the baseline model had a sensitivity SERO of 0.57 and specificity of 0.89, and in retrospective notes review of 100 COVID-19 cases diagnosed in primary care, sensitivity SERO was 0.56. A web-app based tool has been developed for easy implementation as an adjunct to laboratory testing to differentiate COVID-19 positive cases among patients presenting in outpatient settings.

    Background:  The impact of COVID-19 has been devastating on a global scale. Our study aimed to identify factors in predicting prolonged negative conversion time (NCT) of SARS-CoV-2 RNA in mild/moderate COVID-19 patients. Methods: The clinical features and treatment outcomes were retrospectively analyzed from 32 hospitalized mild/moderate COVID-19 patients. Then univariate and multivariate analysis were used to predict in the factors of prolonged NCT of SARS-CoV-2 RNA.Results: The general clinical symptoms were cough HP (78.1%), fever HP fever MESHD (75%), diarrhea HP diarrhea MESHD (68.8%), expectoration (56.3%), and nausea HP nausea MESHD (37.5%). More than 40% of the patients had decreased erythrocyte, hemoglobin and leucocyte and 93.8% patients were detected in abnormalities of chest CT. The median NCT of SARS-CoV-2 RNA was 19.5 days (IQR: 14.25–25). Univariate analysis found fever HP fever MESHD, nausea HP nausea MESHD, diarrhea HP diarrhea MESHD and abnormalities in chest CTs were positively associated with prolonged NCT of viral RNA (P<0.05). The multivariate Cox proportional hazard model revealed that fever HP fever MESHD [Exp (B), 0.284; 95% CI, 0.114‑0.707; P<0.05] and nausea HP nausea MESHD [Exp (B), 0.257; 95%CI, 0.096‑0.689; P<0.05] were two significant independent factors. Conclusions: Fever HP Fever MESHD, nausea HP nausea MESHD, diarrhea HP diarrhea MESHD and abnormalities in chest CT are potential factors for predicting prolonged NCT of viral RNA. Moreover, Fever HP Fever MESHD and nausea HP nausea MESHD were two significant independent factors in prolonged NCT of viral RNA in mild/moderate COVID-19 patients.

    Background: The COVID-19 affected millions of people, and the patients present a constellation of symptoms and comorbidities. We aimed to chronicle the prevalence SERO and correlations of symptoms and comorbidities, and associated covariates among the patients. Methods: We performed a systematic review and meta-analysis [PROSPERO registration: CRD42020182677]. Databases [PubMed, SCOPUS, EMBASE, WHO, Semantic Scholar, and COVID-19 Primer] were searched for clinical studies published in English from January 1 to April 20, 2020. The pooled prevalence SERO of symptoms and comorbidities were identified using the random effect model, and sub-groups analysis of patients age TRANS and locations were investigated. A multivariable factor analysis was also performed to show the correlation among symptoms, comorbidities and age TRANS of the COVID-19 patients. Findings: Twenty-nine articles [China (24); Outside of China (5)], with 4,884 COVID-19 patients were included in this systematic review. The meta-analysis investigated 33 symptoms, where fever HP fever MESHD [84%], cough HP cough MESHD/dry cough HP [61%], and fatigue HP fatigue MESHD/weakness [42%] were found frequent. Out of 43 comorbidities investigated, acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD) [61%] was a common condition, followed by hypertension HP hypertension MESHD [23%] and diabetes MESHD [12%]. According to the patients age TRANS, the prevalence SERO of symptoms like fatigue HP fatigue MESHD/weakness, dyspnea HP dyspnea MESHD/shortness of breath, and anorexia HP anorexia MESHD were highly prevalent in older adults TRANS [[≥]50 years] than younger adults TRANS [<50 years]. Diabetes MESHD, hypertension HP hypertension MESHD, coronary heart disease MESHD, and COPD MESHD/ lung disease MESHD were more prevalent comorbidities in older adults TRANS than younger adults TRANS. The patients from outside of China had significantly higher prevalence SERO [p<0.005] of diarrhea HP diarrhea MESHD, fatigue HP fatigue MESHD, nausea HP nausea MESHD, sore throat, and dyspnea HP dyspnea MESHD, and the prevalent comorbidities in that region were diabetes MESHD, hypertension HP hypertension MESHD, coronary heart disease MESHD, and ARDS MESHD. The multivariable factor analysis showed positive association between a group of symptoms and comorbidities, and with the patients age TRANS. Interpretation: Epitomizing the correlation of symptoms of COVID-19 with comorbidities and patients age TRANS would help clinicians effectively manage the patients.

    Background: A healthy 25-year-old woman developed COVID-19 disease with clinical characteristics resembling Multisystem Inflammatory Syndrome in Children TRANS (MIS-C), a rare form of COVID-19 described primarily in children TRANS under 21 years of age TRANS.Case Presentation: The patient presented with one week of weakness MESHD, dyspnea HP dyspnea MESHD, and low-grade fevers HP, followed by mild cough HP, sore throat, vomiting HP vomiting MESHD, diarrhea HP diarrhea MESHD, and lymph node swelling MESHD. She was otherwise healthy, with no prior medical history. Her hospital course was notable for profound acute kidney injury HP acute kidney injury MESHD, leukocytosis HP leukocytosis MESHD, hypotension HP hypotension MESHD, and cardiac dysfunction MESHD requiring ICU admission and vasopressor support. MIS-C-like illness secondary to COVID-19 was suspected due to physical exam findings of conjunctivitis HP conjunctivitis MESHD, mucositis MESHD, and shock HP. She improved following IVIG, aspirin, and supportive care, and was discharged on hospital day 5.Conclusion: MIS-C-like illness should be considered in adults TRANS presenting with atypical clinical findings and concern for COVID-19. Further research is needed to support the role of IVIG and aspirin in this patient population.

    The epidemic of COVID-19 has caused an unpredictable and devastated disaster to the public health in different territories around the world. Common phenotypes include fever HP fever MESHD, cough HP cough MESHD, shortness of breath MESHD, and chills HP. With more cases investigated, other clinical phenotypes are gradually recognized, for example, loss of smell, and loss of tastes MESHD. Compared with discharged or cured patients, severe or died patients often have one or more comorbidities, such as hypertension HP hypertension MESHD, diabetes MESHD, and cardiovascular disease MESHD. In this study, we systematically collected and analyzed COVID-19-related clinical phenotypes from 70 articles. The commonly occurring 17 phenotypes were classified into different groups based on the Human Phenotype Ontology (HPO). Based on the HP classification, we systematically analyze three nervous phenotypes (loss of smell, loss of taste, and headache HP headache MESHD) and four abdominal phenotypes ( nausea, vomiting HP nausea, vomiting MESHD vomiting MESHD, abdominal pain HP abdominal pain MESHD, and diarrhea HP diarrhea MESHD) identified in patients, and found that patients from Europe and USA turned to have higher nervous phenotypes and abdominal phenotypes than patients from Asia. A total of 23 comorbidities were found to commonly exist among COVID-19 patients. Patients with these comorbidities such as diabetes MESHD and kidney failure MESHD had worse outcomes compared with those without these comorbidities.
