    A retrospective, descriptive study of all patients tested for SARS-CoV2 on admission for illness to a community hospital in Iowa from 3/21/20 thru 6/14/20 consisted of evaluation as to demographics, presentation and hospital course. Ninety-one patients were SARS-CoV2 PCR+ with 63% being male TRANS and a median age TRANS of 60. Cardiovascular disease MESHD was a significant comorbidity in the PCR+ group. Fever HP Fever MESHD, cough HP cough MESHD, dyspnea HP dyspnea MESHD, nausea HP nausea MESHD, emesis MESHD, diarrhea HP diarrhea MESHD, headache HP headache MESHD and myalgias HP myalgias MESHD were significantly more common in that group, as was an elevated CRP, LDH, serum SERO ferritin and transaminases. Overall survival of the COVID-19 patients was 88%, 77% in the critically ill, 59% of those mechanically ventilated and 33% of those requiring new dialysis. Survival was 93% in those not receiving any antivirals. Survival of those treated with hydroxychloroquine-azithromycin was 92%, compared to 86% of those treated with hydroxychloroquine alone. The latter two groups were significantly more ill than the untreated group. A transition from an early intubation strategy to aggressive utilization of high flow nasal cannula and noninvasive ventilation(i.e BiPAP) was successful in freeing up ICU resources.

    Background Since December 2019, there has be an outbreak of coronavirus disease MESHD 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) in Wuhan, China. Nowadays, it rapidly spread across the country and then the worldwide. We aimed to investigate the clinical characteristics of patients with COVID-19.Methods The patients with confirmed COVID-19 admitted between January 25 and February 10, 2020, were enrolled. Epidemiological, demographic, clinical, laboratory, radiological data, and antivirus therapies, were retrospectively collected and analyzed. The 90-day follow-up of these patients was also performed.Results A total of 107 patients were included. The median age TRANS was 55.0 years (range from 18.0 to 85.0 years), and 72 (67.3%) were female TRANS. Ninety-three (86.9%) of the patients had a history of contacting with residents from Wuhan (n=31), or contacting with confirmed COVID-19 patients (n=62) within 2 weeks. Fifty-eight (54.2%) had a family cluster onset. Fever HP Fever MESHD and cough HP cough MESHD were the most common symptoms. Only two patients had diarrhea HP diarrhea MESHD. The most common underlying disease was hypertension HP hypertension MESHD. Lymphopenia HP Lymphopenia MESHD was observed in 26 patients. Fifty-two patients with an elevated level of IL-6. On admission, bilateral patchy shadowing and ground-glass opacity were the typical radiological findings on chest computed tomography. Six patients had an intensive care unit (ICU) stay. Antivirus therapy was performed to all patients. 105 patients discharged with an improved condition, and no death MESHD was occurred during our 90-day follow-up for these patients.Conclusions Patients with COVID-19 in our hospital had relatively mild symptoms, and good prognosis. This study also highlights the importance of human-to-human transmission TRANS in COVID-19.

    Background Although novel pneumonia HP pneumonia MESHD associated with the Corona Virus Disease MESHD 2019 (COVID-19) suddenly broke out in China, China has controlled this epidemic effectively. Therefore, evidence-based descriptions of medical and clinical characteristics in China are necessary.Methods Literatures have been systematically performed a search on PubMed, Embase, Web of Science, GreyNet International, and The Cochrane Library from inception up to March 15, 2020. Quality of evidence was evaluated according to the STROBE checklist, and publication bias MESHD was analyzed by Egger’s test. In the single-arm meta-analysis, A random-effects model was used to obtain a pooled incidence rate. We conducted subgroup analysis according to geographic region and research scale.Results A total of 30 Chinese studies and 1969 patients were included in this meta-analysis. The valid pooled incidence rates of symptoms were as follows: rhinorrhea HP 5.1% (95% CI: 3.7–6.8, I2 = 31.90), diarrhea HP diarrhea MESHD 11.0% (95% CI: 9.3–12.9, I2 = 16.58), pharyngalgia 9.4% (95% CI: 7.5–11.7, I2 = 36.40), headache HP headache MESHD 9.5% (95% CI: 8.5–11.1, I2 = 5.7), and lymphocytopenia MESHD 36.7% (95% CI: 33.8–39.8 I2 = 28.73). Meanwhile, 4.3% (95% CI: 3.5–5.4, I2 = 0.00) of patients were found without any symptoms, although they were diagnosed by RT-PCR. In terms of lung CT imaging, most of the patients showed bilateral mottling or ground-glass opacity, and 7.7% (95% CI: 4.4–12.9, I2 = 35.64) of patients had a crazy-paving pattern. In subgroup analysis, the pooled incidence rate of normal CT presentations in the Wuhan area and outside Wuhan area was 2.3% (95% CI: 1.4–3.6, I2 = 24.78) and 5.8% (95% CI: 4.4–7.7, I2 = 32.76) respectively (P = 0.001).Conclusions The findings suggest that although most of the COVID-19 patients have symptoms or abnormal CT imaging presentations, a few of them accompany with no symptoms or abnormal CT imaging results should also be noticed. The digestive symptoms and lymphocytopenia MESHD may be the potential clinical characteristics, especially for patients with a history of contact with COVID-19. Additionally, the incidence rate of ARDS in the Wuhan area and outside Wuhan area was different; however, the reasons for this phenomenon are unclear.

    Background: SARS-CoV-2 is highly infectious and has been a significant public health threat. Despite typical manifestations of illness are dominated by respiratory symptom, some patients have concurrent gastrointestinal manifestations, including   nausea MESHD, diarrhea HP diarrhea MESHD, and vomiting HP vomiting MESHD. Massive gastrointestinal bleeding MESHD, however, has rarely been reported. Case presentation: We herein describe a case of severe SARS-CoV-2 infected MESHD patient with several risk factors for poor prognosis, including male TRANS, hypertension HP hypertension MESHD, old age TRANS, mixed bacterial infection MESHD and multilobular infiltration on radiological imaging. After improvement of respiratory status, the onset of gastrointestinal bleeding MESHD occurred, probably resulting from direct viral invasion as evidenced by the positive findings for SARS-CoV-2 in the repeat stool specimens. Although aggressive resuscitation was administered, hematochezia HP hematochezia MESHD was uncontrolled. The patient rapidly deteriorated, suffered cardiac arrest HP cardiac arrest MESHD, and expired. Conclusions: Digestive symptoms could be severe in SARS-CoV-2 infected MESHD patients, especially for the high-risk individuals with predisposing conditions. A more thorough protocol for preventing cross-infection MESHD through faecal-oral transmission TRANS should be implemented in the process of patient care and infection MESHD control.

    Background coronavirus disease-19 (COVID-19) has spread to several countries around the world and has become an unprecedented pandemic. We report an extremely rare case of acute acalculous cholecystitis MESHD cholecystitis HP on a COVID-19 patient. In our knowledge, this is the first report of laparoscopic cholecystectomy performed on a COVID-19 patient.Case presentation: a COVID-19 patient was diagnosed with acute acalculous cholecystitis MESHD cholecystitis HP and a multidisciplinary team decided to perform a percutaneous transhepatic biliary drainage (PTBD) as the first treatment. SARS-CoV-2 RNA was not found in the bile fluid. Because of deterioration of the patient’s clinical conditions, laparoscopic cholecystectomy had to be performed and since the gallbladder was gangrenous MESHD, the severe inflammation MESHD made surgery difficult to perform.Conclusions acalculous cholecystitis MESHD cholecystitis HP was related with mechanical ventilation and prolonged total parenteral nutrition, in this case the gangrenous MESHD histopathology pattern and the gallbladder wall ischemia MESHD was probably caused by vascular insufficiency MESHD secondary to severe acute respiratory distress syndrome MESHD respiratory distress HP syndrome of COVID-19 pneumonia MESHD pneumonia HP. The percutaneous transhepatic gallbladder drainage (PTBD) was performed according to Tokyo Guidelines because of high surgical risk. Laparoscopic cholecystectomy was next performed due to no clinical improvement. The absence of viral RNA in the bile highlights that SARS-CoV-2 is not eliminated with the bile while it probably infects MESHD small intestinal enterocytes which is responsible of gastrointestinal symptoms such as anorexia HP anorexia MESHD, nausea, vomiting HP nausea, vomiting MESHD vomiting MESHD, and diarrhea HP diarrhea MESHD. Although the lack of evidence and guidelines about the management of patient with acute cholecystitis MESHD cholecystitis HP during COVID-19 pandemic, laparoscopic cholecystectomy, at most preceded by PTGBD on high surgical risk patients, remains the gold standard for the treatment of acute cholecystitis MESHD cholecystitis HP on COVID-19 patients.

    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: The prevalence SERO and significance of digestive manifestations in COVID-19 remain uncertain. Methods: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, laboratory assessment, imaging, and endoscopic findings from the time of symptom onset TRANS until discharge or death MESHD were manually abstracted from electronic health records to characterize the prevalence SERO, spectrum, and severity of digestive manifestations. Regression analyses were performed to evaluate the association between digestive manifestations and severe outcomes related to COVID-19. Results: A total of 1992 patients across 36 centers met eligibility criteria and were included. Overall, 53% of patients experienced at least one gastrointestinal symptom at any time during their illness, most commonly diarrhea HP diarrhea MESHD (34%), nausea HP nausea MESHD (27%), vomiting HP vomiting MESHD (16%), and abdominal pain HP abdominal pain MESHD (11%). In 74% of cases, gastrointestinal symptoms MESHD were judged to be mild. In total, 35% of patients developed an abnormal alanine aminotransferase or total bilirubin level; these were elevated to less than 5 times the upper limit of normal in 77% of cases. After adjusting for potential confounders, the presence of gastrointestinal symptoms at any time (odds ratio 0.93, 95% confidence interval 0.76-1.15) or liver test abnormalities on admission (odds ratio 1.31, 95% confidence interval 0.80-2.12) were not independently associated with mechanical ventilation or death MESHD. Conclusions: Among patients hospitalized with COVID-19, gastrointestinal symptoms MESHD and liver test abnormalities MESHD were common but the majority were mild and their presence was not associated with a more severe clinical course.

    Background: It’s reported SARS-CoV-2 could transmit via gastrointestinal tract, with or without pulmonary symptoms. However, as far as we know, there is no convenient marker to predict the virus discharge in stool and initial gastrointestinal involvement of COVID-19.Aims: We aimed to investigate the biomarker predicting virus discharge in stool and initial gastrointestinal involvement of COVID-19, which may assist the clinicians to better combat and prevent COVID-19.Methods: The patients complained of initial gastrointestinal involvement MESHD, including vomiting HP vomiting MESHD, diarrhea HP diarrhea MESHD, with or without respiratory symptoms, attending the Sixth People’s Hospital of Wenzhou, and the Second Affiliated Hospital of Wenzhou Medical University, were screened by qRT-PCR for SARS-CoV-2. The Confirmed COVID-19 patients without contaminated ingestion were all enrolled to investigate the association between circulating lymphocyte count and virus discharge, initial gastrointestinal involvement MESHD.Results: 76 COVID-19 patients were finally enrolled in this study (mean age TRANS 44.5, male TRANS 44.7%), with 24 (31.5%) complained of initial gastrointestinal symptoms MESHD. Significantly lower circulating lymphocyte count was found in the patients with positive results of qRT-PCR on stool (p = 0.012). Furthermore, when the circulating lymphocyte count increased from bottom tertile to the 2nd and 3rd tertiles, the risk of initial gastrointestinal involvement decreased by nearly 75% (OR = 0.25, 95% CI: 0.07, 0.98, p = 0.047), 83% (OR = 0.17, 95% CI: 0.05, 0.63, p = 0.008), adjusted for possible confounders.Conclusions: The circulating lymphocyte count is negatively associated with virus discharge in stool in COVID-19 patients, and the risk of initial gastrointestinal involvement also.

    Objectives: To discuss the prevention and containment of COVID-19 at a general hospital in Shenzhen China; to analyze the epidemiological and clinical characteristics of its confirmed patients, which is intended to provide a model for other hospitals in COVID-19 management.Methods: The General Hospital of Shenzhen University sets up 4 medical zones relative to the COVID-19 prevention and containment. In so doing, the suspected patients classified into different kind of ward receive different treatment (Classified and Separated Treatment). The epidemiological distribution and clinical characteristics of 28 confirmed cases TRANS in the hospital were analyzed.Results: There are no medical personnel infected cases, no cross-infection MESHD among the patients in the hospital, and no misdiagnosis or missed diagnosis of COVID-19. The majority of cases in the group is from 15 to 60 years old, 25 cases had a definite travel TRANS history or close contact TRANS history in the epidemic area, and parents TRANS and spouses of the confirmed patients are the main contact groups. Fever HP Fever MESHD and respiratory symptoms have a high proportion, 4 diarrhea HP diarrhea MESHD and 4 asymptomatic TRANS cases. Additionally, the decrease of lymphocyte is observed in 8 cases. Chest CT scan shows viral pneumonia HP pneumonia MESHD in 14 cases,All patients were confirmed by nucleic acid tests.Conclusions: Classified and Separated Treatment facilitates management of COVID-19 in the general hospital. Relative to suspected patients in the general hospital, diagnosis matters more than treatment. Epidemiological history, lymphocyte count, and chest CT scan play an important role as the indicator in early diagnosis of COVID-19.

    Background: Prolonged nucleic acid conversion and false-negative results of real-time reverse transcription polymerase chain reaction (RT-PCR) might occur in some patients with COVID-19 rather than recurrence of infection MESHD. Here, we reported four cases of COVID-19 with prolonged nucleic acid conversion and false-negative results of RT-PCR in our institution.Case presentation: Case 1: A 36-year-old- male TRANS patient complained of coughing HP up phlegm one week before admission. His chest X-rays showed mild pneumonia HP pneumonia MESHD in the right lung. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also had negative results of RT-PCR twice (the 6th and 8th tests) from a total of 11 swab tests. Case 2: A 54-year-old- male TRANS patient complained of shortness of breath MESHD that worsened with activity. He had a comorbidity of diabetes MESHD. His chest X-rays showed inhomogeneous opacity on bilateral paracardial and lateral aspects. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also had negative results of RT-PCR once (the 5th test) from a total of 8 swab tests. Case 3: A 47-year-old man presented with complaints of fever HP fever MESHD, cough HP cough MESHD, sore throat, and diarrhea HP diarrhea MESHD. He had comorbidities of asthma HP asthma MESHD and heart rhythm disorders MESHD. His chest X-rays showed bilateral pneumonia HP pneumonia MESHD. His swab test was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, he also showed negative results of RT-PCR twice (the 4th and 6th tests) from a total of 11 swab tests. Case 4: A 56-year-old- female TRANS complained of lethargy HP lethargy MESHD and diarrhea HP diarrhea MESHD. She has a history of hyperthyroidism HP hyperthyroidism MESHD. His chest X-rays showed bilateral pneumonia HP pneumonia MESHD. She was confirmed positive for SARS-Cov-2. Besides the last two consecutive negative results, she also had negative results of RT-PCR twice (the 2nd and 10th tests) from a total of 14 swab tests.Conclusions: Our cases further confirmed TRANS the occurrence of prolonged nucleic acid conversion and the possibility of false negative results of RT-PCR in patients with COVID-19 instead of recurrence of infection MESHD. These findings might have an implication on the management of patients with COVID-19 who have already clinically and radiologically recovered, particularly related to subsequent spreading of the infection MESHD in the community.
