    Background In December 2019, coronavirus disease MESHD 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) emerged in Wuhan, Hubei, China. And, it has become a global pandemic. Describe the patient's clinical symptoms in detail, finding markers that predict the prognosis of patients with COVID-19 are of great value.MethodsIn this multicenter, retrospective study, 476 patients with COVID-19 were recruited from a consecutive series. After screening, a total of 395 patients were included in this study. All-cause death MESHD was the primary endpoint. All patients were followed up from admission till discharge or death MESHD.ResultsThe dominant symptoms observed in the study included fever HP fever MESHD on admission, cough HP, fatigue HP fatigue MESHD and shortness of breath MESHD. The most frequent comorbidities were hypertension HP hypertension MESHD and diabetes MESHD. Compared with patients with higher CD4+T cells level, patients with lower CD4+T cells level were older and were more frequently male TRANS. In terms of laboratory findings, lymphocyte count, CD4+T cell count, CD8+T cell count were significantly lower in low group than in higher group. The case in-hospital death rate was significant higher in patients with lower CD4+T level. After adjusting for potential confounding factors, CD4+T count below the lower limit of normal showed independent prognostic value for all-cause in-hospital death MESHD in patients with COVID-19. Conclusions: Reductions in lymphocytes and lymphocyte subsets are common in COVID-19 patients, especially in severe cases. It is the CD8+T count, not the CD4+T count, that reflected the severity of the patient’s disease. Lower CD4+T count is independently associated with an increased rate of in-hospital death.

    Objective: To report three patients infected with COVID-19 with severe respiratory syndrome MESHD requiring intubation, who developed acute demyelinating encephalomyelitis MESHD ( ADEM MESHD). Method: Patient data were obtained from medical records from the North Memorial Health Hospital, Robbinsdale, MN, USA Results: Three patients (two men and one woman, aged TRANS 38 - 63) presented with fatigue HP fatigue MESHD, cough HP cough MESHD and fever HP fever MESHD leading to development of acute respiratory distress syndrome MESHD respiratory distress HP syndrome secondary to COVID-19 infection requiring intubation and ventilatory support. Two patients were unresponsive, one with strong eye deviation to the left and the third patient had severe diffuse weakness MESHD. MRI in all patients showed findings consistent with ADEM MESHD. CSF showed elevated protein in all patients with normal cell count and no evidence of infection MESHD, including negative COVID-19 PCR. All three of the patients received Convalescent plasma SERO therapy for COVID-19. All patients were treated with intravenous corticosteroids and improved, although two responded minimally. Two patients treated with IVIG showed no further improvement. Conclusion: Neurological complications from COVID-19 are being rapidly recognized. Our three cases highlight the occurrence of ADEM MESHD as a postinfectious/immune mediated complication of COVID-19 infection MESHD, which may be responsive to corticosteroid treatment. Early recognition of this complication and treatment is important to avoid long term complications.

    Background: New coronavirus disease 2019 (COVID-19) poses a severe threat to human life, and causes a global pandemic. The purpose of current research is to explore the onset and progress of the pandemic with a novel perspective using Baidu Index.Methods: We collected the confirmed data of COVID-19 infection between January 11, 2020, and April 22, 2020, from the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University (JHU). Based on known literature, we obtained the search index values of the most common symptoms of COVID-19, including fever HP, cough HP, fatigue HP, sputum production, and shortness of breath. Spearman's correlation analysis was used to analyze the association between the Baidu index values for each COVID-19-related symptoms and the number of confirmed cases TRANS. Regional differences among 34 provinces/ regions were also analyzed. Results: Daily growth of confirmed cases TRANS and Baidu index values for each symptoms presented a robust positive correlation during the outbreak ( fever HP: rs=0.705, p=9.623×10-6; cough HP: rs=0.592, p=4.485×10-4; fatigue HP: rs=0.629, p=1.494×10-4; sputum production: rs=0.648, p=8.206×10-5; shortness of breath: rs=0.656, p=6.182×10-5). The average search-to-confirmed interval is 19.8 days in China ( fever HP: 22 days, cough HP: 19 days, fatigue HP: 20 days, sputum production: 19 days, and shortness of breath: 19 days). We discovered similar results in the top 10 provinces/regions, which had the highest cumulative cases. Conclusion: Search terms of COVID-19- related symptoms on the Baidu search engine can be used to early warn the outbreak of the epidemic. Relevant departments need to pay more attention to areas with high search index and take precautionary measures to prevent these potentially infected persons from spreading further. Baidu search engine can reflect the public's attention to the pandemic and regional epidemics of viruses. Based on changes in the Baidu index value, we can predict the arrival of the peak confirmed cases TRANS. The clinical characteristics related to COVID-19- including fever HP, cough HP, fatigue HP, shortness of breath, deserve more attention during the pandemic.

    Background: Currently, coronavirus disease-2019 (COVID-19) is continuously and rapidly circulating, resulting in serious and extensive impact on human health. Due to the absence of antiviral medicine for COVID-19 thus far, it is desperately need to develop the effective medicine. Traditional Chinese medicine (TCM) has been widely applied in the treatment of epidemic diseases MESHD in China, hoping to produce clinical efficacy and decrease the use of antibiotics and glucocorticoid. The aim of this study is to evaluate the efficacy and safety of Baidu Jieduan Granule in curing COVID-19. Methods/design: This multicenter, open-label randomized controlled trial is conducted 300 cases with COVID-19. The patients will be randomly (1:1) divided into treatment group or control group. All cases will receive standard therapy at the same time. The experiment group will receive Baidu Jieduan Granule treatment twice a day for 14 days. The outcomes are assessed at baseline and at 3, 5, 7, 14 days after treatment initiation. The primary outcome is the rate of symptom ( fever HP fever MESHD, fatigue HP fatigue MESHD, and coughing HP) recovery. Adverse events will be monitored throughout the trial.Discussion: The study will provide a high-quality clinical evidence to support the efficacy and safety of Baidu Jieduan Granule in treatment of severe COVID-19, and also enrich the theory and practice of TCM in treating COVID-19.

    Objective : Data regarding the clinical characteristics of COVID-19 infection MESHD is rapidly accumulating. However, most studies thus far are based on hospitalized patients and lack longitudinal follow up. As the majority of COVID-19 cases are not hospitalized, prospective studies of symptoms in the population presenting to primary care are needed. Here, we assess the longitudinal dynamic of clinical symptoms in non-hospitalized individuals prior to and throughout the diagnosis of SARS-CoV-2 infection MESHD. Design Data on symptoms were extracted from electronic health records (EHR) consisting of both results of PCR tests and symptoms recorded by primary care physicians, and linked longitudinal MESHD self reported symptoms. Setting The second largest Health Maintenance Organization in Israel , Maccabi Health Services Participants From 1/3/2020 to 07/06/2020, information on symptoms from either surveys or primary care visits was available for 206,377 individuals, including 2,471 who tested positive for COVID-19. Main Outcomes Longitudinal prevalence SERO of clinical symptoms in COVID-19 infection MESHD diagnosed by PCR testing for SARS-CoV-2 from nasopharyngeal swabs. Results: In adults TRANS, the most prevalent symptoms recorded in EHR were cough HP (11.6%), fever HP fever MESHD (10.3%), and myalgia HP myalgia MESHD (7.7%) and the most prevalent self-reported symptoms were cough HP (21%), fatigue HP fatigue MESHD (19%) and rhinorrhea HP rhinorrhea MESHD and/or nasal congestion (17%). In children TRANS, the most prevalent symptoms recorded in the EHR were fever HP fever MESHD (7%), cough HP cough MESHD (5.5%) and abdominal pain HP abdominal pain MESHD (2.4%) . Emotional disturbances were documented in 15.9% of the positive adults TRANS and 4.2% of the children TRANS. Loss of taste and smell, either self-reported or documented by a physician, 3 weeks prior to testing, were the most discriminative symptoms in adults TRANS (OR =11.18 and OR=5.47 respectively). Additional symptoms included self reported headache HP headache MESHD (OR = 2.03) and fatigue HP fatigue MESHD (OR = 1.73) and a documentation of syncope HP syncope MESHD, rhinorrhea HP rhinorrhea MESHD (OR = 2.09 for both ) and fever HP fever MESHD (OR= 1.62 ) by a physician. Mean time to recovery TRANS was 23.5 +- 9.9 days. Children TRANS had a significantly shorter disease duration (21.7 +- 8.8 days, p-value=0.01). Several symptoms, including fatigue HP fatigue MESHD, myalgia HP myalgia MESHD, runny nose and shortness of breath MESHD were reported weeks after recovery. Conclusions As the COVID-19 pandemic progresses rapidly worldwide, obtaining accurate information on symptoms and their progression is of essence. Our study shed light on the full clinical spectrum of symptoms experienced by infected individuals in primary care, and may alert physicians for the possibility of COVID-19 infection MESHD.

    Objective: To examine the clinical characteristics and identify independent risk factors for in-hospital mortality of 2019 novel coronavirus (COVID-19) pneumonia HP pneumonia MESHD.Methods: A total of 156 patients diagnosed with COVID-19 pneumonia HP pneumonia MESHD at the central Hospital of Wuhan from January 29, 2020, to March 20, 2020 were enrolled in this single-centered retrospective study. Their epidemiological parameters, clinical presentations, underlying diseases, laboratory test results and disease outcomes were collected and analyzed. Results: The median age TRANS of enrolled patients was 66. Underlying diseases were identified in 101 patients, with hypertension HP hypertension MESHD being the most common one, followed by cardiovascular disease MESHD and diabetes MESHD. The most common symptoms identified upon admission were fever HP fever MESHD, cough HP, dyspnea HP dyspnea MESHD and fatigue HP. Compared to survival cases, patients who dead during hospitalization had higher plasma SERO levels of D-dimer, creatinine, creatine kinase, lactate dehydrogenase, lactate and lower percentage of lymphocytes (LYM [%]), platelet count and albumin levels. Most enrolled patients received anti-biotics and anti-viral treatment. In addition, 60 patients received corticosteroid and 51 received intravenous immunoglobulin infusion. 44 patients received noninvasive ventilation, 19 received invasive ventilation. Respiratory failure HP Respiratory failure MESHD was the most frequently observed complication (106 [67.9%]), followed by sepsis HP sepsis MESHD (103 [66.0%]), acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD) (67 [42.9%]) and septic shock MESHD shock HP (50 [32.1%]). Multivariable regression suggested that advanced age TRANS (OR [odds ratio]= 1.059, 95% CI [confidence interval]: 1.011-1.110, P= 0.016) and elevated lactate level upon admission (OR= 2.411, 95% CI: 1.177-4.941, P= 0.016) were independent risk factors for in-hospital mortality for COVID-19 infection MESHD. Meanwhile, increased LYM (%) at admission (OR= 0.798, 95% CI: 0.728-0.876, P< 0.001) indicated a better prognosis. Conclusions: In this study, we discovered that age TRANS, LYM (%) and lactate level upon admission were independent factors that could influence in-hospital mortality rate.

    Background & AimCoronavirus 2019 (COVID-19) outbreak in the Middle East was initially reported in Qom-Iran. Clinical and epidemiologic and mortality risk factors details have not been already fully explained.MethodIn a retrospective study, the hospitalized adult TRANS patients with laboratory diagnosed COVID-19 between February 25 to March 20, 2020 were enrolled. A checklist including demographic, clinical, laboratorial, imaging, and treatment data was completed for each of the participant. The data were extracted from electronic medical records. In case of lack of information, a member of the research team contacted them via phone. All the dead patients and the first one hundred survived patients with these criteria were enrolled in the study. Outcome defined as death MESHD or discharge of patients.ResultsOf admitted patients, 200 patients who had been discharged or died were involved in this study. The majority of them were male TRANS (56%). The mean age TRANS of all patients was 62.63 ± 14.9. Co-morbidity was reported in 124 (62%) patients in which hypertension HP hypertension MESHD was the most common. The most frequent clinical presentations were dyspnea HP dyspnea MESHD in 169 (84.5%), cough HP cough MESHD in 150 (75%), and fatigue HP fatigue MESHD/weakness in 123 (61.5%) patients. The main complications were respiratory failure HP respiratory failure MESHD and acute respiratory distress syndrome MESHD respiratory distress HP syndrome with prevalence SERO of 143 (71.5%) and 105 (52.5%), accordingly. Multiple logistic models showed that decline of hemoglobin level (OR = 10.09), neutrophilia HP (OR = 3.48), high blood SERO urea nitrogen (OR = 4.29,), SpO2 ≤ 90% (OR = 3.38), and presence of patchy consolidation (OR = 6.81) were associated with poor outcome.ConclusionCOVID-19 disease has multiple aspects. CT scan findings, complete blood SERO count with differential, high blood SERO urea nitrogen and SpO2 are related to mortality. Hence needs to pay serious attention during admitting and surveillance, particularly among elderly TRANS patients and who with preexisting morbidities.

    Background A striking characteristic of Coronavirus Disease MESHD 2019(COVID-19) is the coexistence of clinically mild and severe cases. A comprehensive analysis of multiple risk factors predicting progression to severity is clinically meaningful. Methods The patients were classified into moderate and severe groups. The univariate regression analysis was used to identify their epidemiological and clinical features related to severity, which were used as possible risk factors and were entered into a forward-stepwise multiple logistic regression analysis to develop a multiple factor prediction model for the severe cases.Results 255 patients (mean age TRANS, 49.1±SD 14.6) were included, consisting of 184 (72.2%) moderate cases and 71 (27.8%) severe cases. The common symptoms were dry cough HP (78.0%), sputum (62.7%), and fever HP fever MESHD (59.2%). The less common symptoms were fatigue HP fatigue MESHD (29.4%), diarrhea HP diarrhea MESHD (25.9%), and dyspnea HP dyspnea MESHD (20.8%). The univariate regression analysis determined 23 possible risk factors. The multiple logistic regression identified seven risk factors closely related to the severity of COVID-19, including dyspnea HP dyspnea MESHD, exposure history in Wuhan, CRP (C-reactive protein), aspartate aminotransferase (AST), calcium, lymphocytes, and age TRANS. The probability model for predicting the severe COVID-19 was P=1/1+exp (-1.78+1.02×age+1.62×high- transmission TRANS-setting-exposure +1.77× dyspnea MESHD+1.54×CRP+1.03×lymphocyte+1.03×AST+1.76×calcium). Dyspnea HP Dyspnea MESHD (OR=5.91) and hypocalcemia HP hypocalcemia MESHD (OR=5.79) were the leading risk factors, followed by exposure to a high- transmission TRANS setting (OR=5.04), CRP (OR=4.67), AST (OR=2.81), decreased lymphocyte count (OR=2.80), and age TRANS (OR=2.78). Conclusions This quantitative prognosis prediction model can provide a theoretical basis for the early formulation of individualized diagnosis and treatment programs and prevention of severe diseases.

    Background: Preventing communicable diseases requires understanding the spread, epidemiology, clinical features, progression, and prognosis of the disease. Early identification of risk factors and clinical outcomes might help to identify critically ill patients, provide proper treatment and prevent mortality. Methods: We conducted a prospective study in patients with flu-like symptoms referred to the imaging department of a tertiary hospital in IRAN between 3 March 2020 and 8 April 2020. Patients with COVID-19 were followed up to check their health condition after two months. The categorical data between groups were analyzed by Fisher exact test and continuous data by Wilcoxon Rank-Sum Test. Findings: 319 patients (mean age TRANS 45.48 years, 177 women) were enrolled. Fever HP Fever MESHD, dyspnea HP dyspnea MESHD, weakness MESHD, shivering HP, C-reactive protein (CRP), fatigue HP fatigue MESHD, dry cough MESHD cough HP, anorexia HP anorexia MESHD, anosmia HP anosmia MESHD, ageusia MESHD, dizziness MESHD, sweating and age TRANS were the most important symptoms of COVID-19 infection MESHD. Traveling TRANS in past three months, asthma HP asthma MESHD, taking corticosteroids, liver disease MESHD, rheumatological disease MESHD, cough HP cough MESHD with sputum, eczema HP eczema MESHD, conjunctivitis HP conjunctivitis MESHD, tobacco use, and chest pain HP chest pain MESHD did not have any relationship with COVID-19. Interpretation: Finding clinical symptoms for early diagnosis of COVID-19 is a critical part of prevention. These symptoms can help in the assessment of disease progression. To the best of our knowledge, some of the effective features on the mortality due to COVID-19 are investigated for the first time in this research. Funding: None
