    Background: Assigning meaningful probabilities of SARS CoV2 infection risk TRANS infection risk TRANS presents a diagnostic challenge across the continuum of care. Methods: We integrated patient symptom and test data using machine learning and Bayesian inference to quantify individual patient risk of SARS CoV 2 infection MESHD. We trained models with 100,000 simulated patient profiles based on thirteen symptoms, estimated local prevalence SERO, imaging, and molecular diagnostic performance SERO from published reports. We tested these models with consecutive patients who presented with a COVID 19 compatible illness at the University of California San Diego Medical Center over 14 days starting in March 2020. Results: We included 55 consecutive patients with fever HP fever MESHD (78%) or cough HP cough MESHD (77%) presenting for ambulatory (n=11) or hospital care (n=44). 51% (n=28) were female TRANS, 49% were age TRANS <60. Common comorbidities included diabetes MESHD (22%), hypertension HP hypertension MESHD (27%), cancer MESHD (16%) and cardiovascular disease MESHD (13%). 69% of these (n=38) were RT-PCR confirmed positive for SARS CoV2 infection, 11 had repeated negative nucleic acid testing and an alternate diagnosis. Bayesian inference network, distance metric learning, and ensemble models discriminated between patients with SARS CoV2 infection MESHD and alternate diagnoses with sensitivities SERO of 81.6 to 84.2%, specificities of 58.8 to 70.6%, and accuracies of 61.4 to 71.8%. After integrating imaging and laboratory test statistics with the predictions of the Bayesian inference network, changes in diagnostic uncertainty at each step in the simulated clinical evaluation process were highly sensitive to location, symptom, and diagnostic test choices. Conclusions: Decision support models that incorporate symptoms and available test results can help providers diagnose SARS CoV2 infection MESHD in real world settings.

    Background: Understanding of the true asymptomatic TRANS rate of infection of SARS-CoV-2 MESHD is currently limited, as is understanding of the population-based seroprevalence SERO after the first wave of COVID-19 within the UK. The majority of data thus far come from hospitalised patients, with little focus on general population cases, or their symptoms. Methods: We undertook enzyme linked immunosorbent assay SERO characterisation of IgM and IgG responses against SARS-CoV-2 spike glycoprotein and nucleocapsid protein of 431 unselected general-population participants of the TwinsUK cohort from South-East England, aged TRANS 19-86 (median age TRANS 48; 85% female TRANS). 382 participants completed prospective logging of 14 COVID-19 related symptoms via the COVID Symptom Study App, allowing consideration of serology alongside individual symptoms, and a predictive algorithm for estimated COVID-19 previously modelled on PCR positive individuals from a dataset of over 2 million. Findings: We demonstrated a seroprevalence SERO of 12% (51participants of 431). Of 48 seropositive individuals with full symptom data, nine (19%) were fully asymptomatic TRANS, and 16 (27%) were asymptomatic TRANS for core COVID-19 symptoms: fever HP fever MESHD, cough HP cough MESHD or anosmia HP anosmia MESHD. Specificity of anosmia HP anosmia MESHD for seropositivity was 95%, compared to 88% for fever HP fever MESHD cough HP and anosmia HP anosmia MESHD combined. 34 individuals in the cohort were predicted to be Covid-19 positive using the App algorithm, and of those, 18 (52%) were seropositive. Interpretation: Seroprevalence SERO amongst adults TRANS from London and South-East England was 12%, and 19% of seropositive individuals with prospective symptom logging were fully asymptomatic TRANS throughout the study. Anosmia HP demonstrated the highest symptom specificity for SARS-CoV-2 antibody SERO response. Funding: NIHR BRC, CDRF, ZOE global LTD, RST-UKRI/MRC

    Background: Healthcare workers are at increased risk of contracting SARS-CoV-2 and potentially causing institutional outbreaks. Staff testing is critical in identifying and isolating infected individuals while also reducing unnecessary workforce depletion. Tygerberg Hospital implemented an online pre-registration system to expedite staff and cluster testing. Objectives: We aimed to identify (1) specific presentations associated with a positive or negative result for SARS-CoV-2 and (2) staff sectors where enhanced strategies for testing might be required. Methods: Retrospective descriptive study involving all clients making use of the hospital's pre-registration system during May 2020. Results: Of 799 clients, most were young and female TRANS with few comorbidities. The most common occupation was nurses followed by administrative staff, doctors and general assistants. Doctors tested earlier compared to other staff (median: 1.5 vs 4 days). The most frequent presenting symptoms were headache HP headache MESHD, sore throat, cough HP cough MESHD and myalgia HP myalgia MESHD. Amongst those testing positive (n=105), fever HP fever MESHD, altered smell, altered taste sensation, chills HP and history of fever HP fever MESHD were the most common symptoms. Three or more symptoms was more predictive of a positive test, but 12/145 asymptomatic TRANS clients also tested positive. Conclusion: Staff coronavirus testing using an online pre-registration form is a viable and acceptable strategy. While some presentations are less likely to be associated with SARS-CoV-2 infection MESHD, no symptom can completely exclude it. Staff testing should form part of a bundle of strategies to protect staff including wearing masks, regular hand washing, buddy screening, physical distancing, availability of PPE and special dispensation for COVID-19-related leave.

    Background SARS-Cov-2 infects MESHD not only adults TRANS, but also children TRANS, including pediatric surgery patients with acute abdomen. Here, we report a pediatric surgery case with incarcerated inguinal hernia MESHD inguinal hernia HP and suspected COVID-19.Case presentation: A 11-month-old male TRANS was brought to our emergency department with the main complaint of recurrent yellowish-green vomiting HP vomiting MESHD that was experienced from one day before admission. High fever MESHD fever HP and shortness of breath MESHD were also reported. This patient was also suffering from moderate dehydration HP dehydration MESHD. Neither history of contact with a confirmed case TRANS of COVID-19 nor traveling TRANS from any local transmission TRANS area were found. However, a SARS-CoV-2 rapid antibody test SERO revealed a positive result. A lump in the left scrotum that persisted during admission was found. Fluid resuscitation and nasogastric tube placement for decompression was performed. Manual reduction was attempted but failed to reduce the lump. Accordingly, we decided to perform an emergency high ligation using tertiary protection regulations, i.e., full personal protective equipment (PPE) for COVID-19. Intraoperatively, we found a small intestine loop trapped in the scrotum and stuck in the inguinal canal. Postoperatively, the baby was continued to be managed as a patient with COVID-19 while waiting for the real-time reverse transcription polymerase chain reaction (RT-PCR) results.Conclusions During the COVID-19 pandemic, surgeons should always be aware of the possibility of cross- transmission TRANS from the patient, since children TRANS are also susceptible to SARS-CoV-2 infection MESHD. When and wherever possible, surgeons should perform the procedure in the quickest and most effective manner to shorten exposure time with patient and anesthetic aerosols as well as using appropriate PPE.

    Objective: SARS-Cov-2 infection MESHD or COVID-19 is a global pandemic. From the time of identification to till, multiple clinical symptoms and parameters have been identified by the researchers of various countries and regions regarding the diagnosis and presentations of COVID-19 disease. In this manuscript, we investigated the primary symptoms and basic hematological presentations of SARS-CoV-2 infection MESHD among the Bangladeshi patients. Methodology: We have collected the disease history of mild to moderate degree of COVID-19 patients; hematological MESHD and biochemical on admission reports of moderate degree COVID-19 patients. All of them were tested positive for SARS-CoV-2 by RT-PCR in different institutes in Bangladesh. Results: According to this study though COVID-19 patients in Bangladesh commonly presented with fever HP fever MESHD, cough HP cough MESHD, fatigue HP fatigue MESHD, shortness of breath MESHD, and sore throat, but symptoms like myalgia HP myalgia MESHD, diarrhea HP diarrhea MESHD, skin rash HP skin rash MESHD, headache HP headache MESHD, Abdominal pain HP Abdominal pain MESHD/cramp, nausea, vomiting HP nausea, vomiting MESHD vomiting MESHD, restlessness HP, and a higher temperature of >1000F have a greater presentation rate and more frequent than other published studies. CRP and Prothrombin time was found to increase in all the patients. Serum SERO ferritin, ESR, SGPT, and D-Dimer were found increased among 53.85%, 80.43, 44%, and 25% patients respectively. 17.39% of the patients had leukocytosis HP leukocytosis MESHD and neutrophilia HP. 28.26% of patients presented with lymphocytopenia MESHD. 62.52% of patients had mild erythrocytopenia. Conclusion: Despite some similarities, our study has evaluated a different expression in presenting symptoms in the case of COVID-19 patients in Bangladesh. CRP, Prothrombin time, serum SERO ferritin, ESR, SGPT, D-Dimer, erythrocytopenia, and lymphocytopenia MESHD can be initial diagnostic hematological findings and assessment for prognosis COVID-19 disease. Also, gender TRANS variations have a different scenario of clinical and laboratory appearance in this region.

    Introduction Coronavirus Disease (COVID-19) is caused by SARS-CoV-2 infection MESHD. Indonesia officially established the first COVID-19 confirmation case in early March 2020. East Kalimantan has been determined as a candidate for the new capital of Indonesia since 2019. This makes Abdul Wahab Sjahranie Hospital Samarinda as the largest hospital there has been designated as the main referral hospital for COVID-19 patients in East Kalimantan. We report the epidemiological, clinical, laboratory, and radiological characteristics of these patients. Methods All patients with laboratory-confirmed COVID-19 by RT-PCR were admitted to Abdul Wahab Sjahranie Hospital in Samarinda. We retrospectively collected and analyzed data on patients with standardized data collection from medical records. Results By May 8, 2020, 18 admitted hospital patients had been identified as having laboratory-confirmed COVID-19. Most of the infected MESHD patients were men (16 [88.9%] patients); less than half had underlying diseases (7 [38.9%] patients). Common symptoms at the onset TRANS of illness were cough HP (16 [88.9%] patients), sore throat (8 [44.4%] patients), and fever HP fever MESHD (8 [44.4%] patients). Laboratory findings of some patients on admission showed anemia HP anemia MESHD. Levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were increased in 10 (55.6%) of 18 patients. On admission, abnormalities in chest x-ray images were detected in 6 (33.3%) patients who had pneumonia HP pneumonia MESHD. The mean duration from the first hospital admission to discharge was 33.1 days. Discussion The majority of COVID-19 patients are male TRANS. COVID-19 comorbidities were found in several patients. The main clinical symptoms of COVID-19 in this study were cough HP cough MESHD, sore throat, and fever HP fever MESHD. The abnormal laboratory finding in COVID-19 patients is anemia HP anemia MESHD, an increase in AST and ALT levels, and chest x-ray images of pneumonia HP pneumonia MESHD. All patients are in mild condition. The average length of hospital admission patients to discharge is more than 30 days. Conclusion Although all patients are in mild condition, the inability of a local laboratory to check for positive confirmation of COVID-19 makes the admission period of the patient in the hospital very long. The availability of RT-PCR tests at Abdul Wahab Sjahranie Hospital Samarinda will greatly assist the further management of COVID-19 patients.

    Background: A new pathogenic disease named COVID-19 became a global threat, first reported in Wuhan, China, in December 2019. The number of affected cases growing exponentially and now, more than 210 countries confirmed the cases TRANS. Objective: This meta-analysis aims to evaluate risk factors, the prevalence SERO of comorbidity, and clinical characteristics in COVID-19 death MESHD patients compared to survival patients that can be used as a reference for further research and clinical decisions. Methods: PubMed, Science Direct, SAGE were searched to collect data about demographic, clinical characteristics, and comorbidities of confirmed COVID-19 patients from January 1, 2020, to May 17, 2020. Meta-analysis was performed with the use of Review Manager 5.3 Results: Eighty-five studies were included in Meta-analysis, including a total number of 67,299 patients with SARS-CoV-2 infection MESHD. Males TRANS are severely affected or died than females TRANS (OR = 2.26, p < 0.00001; OR = 3.59, p < 0.00001) are severely affected, or died by COVID-19 and cases with age TRANS [≥]50 are at higher risk of death MESHD than age TRANS <50 years (OR=334.23). Presence of any comorbidity or comorbidities like hypertension HP hypertension MESHD, cardiovascular disease MESHD, diabetes MESHD, cerebrovascular disease MESHD, respiratory disease MESHD, kidney disease MESHD, liver disease MESHD, malignancy MESHD significantly increased the risk of death compared to survival (OR = 3.46, 3.16, 4.67, 2.45, 5.84, 2.68, 5.62, 2.81,2.16). Among the clinical characteristics such as fever HP fever MESHD, cough HP cough MESHD, myalgia HP myalgia MESHD, diarrhea HP diarrhea MESHD, abdominal pain HP abdominal pain MESHD, dyspnea HP dyspnea MESHD, fatigue HP fatigue MESHD, sputum production, chest tightness HP chest tightness MESHD headache HP and nausea or vomiting HP nausea or vomiting MESHD, only fatigue HP fatigue MESHD (OR = 1.31, 95%) and dyspnea HP dyspnea MESHD increased the death significantly (OR= 1.31, 4.57). The rate of death of COVID-19 cases is 0.03-times lower than the rate of survival (OR = 0.03). Conclusion Our result indicates that male TRANS patients are affected severely or died, the rate of death is more in the age TRANS [≥]50 group, and the rate of death is affected by comorbidities and clinical symptoms.

    Background Towards the end of December 2019, the Wuhan health commission declared an outbreak of clusters of pneumonia HP pneumonia MESHD in patients. Sequencing indicated that this disease (COVID-19) was caused by a novel coronavirus (SARS-CoV-2). The outbreak of COVID-19 is currently still underway.Methods We recruited 75 SARS-CoV-2 infected MESHD patients admitted to the Center of Infectious Disease division 2 of Beijing Ditan Hospital from Jan 20 to Mar 20, 2020. Epidemiological, demographic, clinical, radiological features, laboratory data were analyzed.Results Of the 75 patients, 42(56%) patients were male TRANS and 33(44%) patients were female TRANS. The mean age TRANS of all patients was 41.5 ± 19.4 years. Male TRANS patients were more likely to become severe. There were 9 family clusters accounted for 44 patients. Patients classified as being severe had a higher frequency of fever HP fever MESHD upon admission than patients classified as moderate cases. For moderate patients, the median duration of viral shedding was 25(9.5, 42) days (range 1–63 days) from the first positive nucleic acid test compared to 14(9, 21.25) days (range 2–62 days) for severe cases. The difference between the two groups was statistically significant (p = 0.041). Cox regression analyses indicated that disease status and CRP were the factors that affect the duration of viral shedding. Virus clearance was significantly faster in severe patients compared to moderate patients(p = 0.011), and patients with CRP range in 2–10 times higher than upper limit of normal value had longer duration of viral shedding(p = 0.012). CRP and CD4 + T lymphocyte was negative correlated, and the relationship between CRP and CD4 + T lymphocyte was statistically significant (P = 0.003), with a correlation coefficient of -0.564. During the second week following the onset of illness, severe cases had higher WBC, NEU and CRP, but lower LYM, MON and EOS as compared with moderate cases (all P < 0.05). Severe cases still had lower lymphocyte counts and higher CRP than moderate cases in the third week.Conclusions Viral clearance was significantly prolonged in moderate patients, and those CRP in 2–10 times higher than upper limit of normal value. Immune response may affect the duration of viral shedding. Severe cases had a persistence lower lymphocyte count and higher CRP than moderate cases.

    Backgrounds In December 2019, a pneumonia HP pneumonia MESHD associated with the severe acute respiratory syndrome coronavirus 2 MESHD (SARS-Cov-2) emerged in Wuhan city, China. As of 20 Feb 2020, a total of 2,055 medical staff infected with SARS-Cov-2 in China had been reported. The predominant cause of the infection MESHD and the failure of protection among medical staff remains unclear. We sought to explore the epidemiological, clinical characteristics and prognosis of novel coronavirus-infected MESHD medical staff.Methods Medical staff who infected with SARS-Cov-2 and admitted to Union Hospital, Wuhan between 16 Jan, 2020 to 25 Feb, 2020 were included retrospectively. Epidemiological, clinical and radiological data were compared by occupation and analyzed with the Kaplan-Meier and Cox regression methods.Results A total of 101 medical staff (32 males TRANS and 69 females TRANS; median age TRANS: 33 years old) were included in this study and 74% were nurses. None had an exposure to Huanan seafood wholesale market or wildlife. A small proportion of the cohort had contact with specimens (3%) as well as patients infected with SARS-Cov-2 in fever HP clinics (15%) and isolation wards (3%). 80% of medical staff showed abnormal IL-6 levels and 33% had lymphocytopenia MESHD. Chest CT mainly manifested as bilateral (62%), septal/subpleural (77%) and ground­glass opacities (48%). The major differences between doctors and nurses manifested in laboratory indicators. As of the last observed date, no patient was transferred to intensive care unit or died, and 98 (97%) had been discharged. Fever HP Fever MESHD (HR=0.57; 95% CI 0.36-0.90) and IL-6 levels greater than >2.9 pg/ml (HR=0.50; 95% CI 0.30-0.86) on admission were unfavorable factors for discharge.Conclusions Our findings suggested that the infection of medical staff mainly occurred at the early stages of SARS-CoV-2 epidemic MESHD in Wuhan, and only a small proportion of infection MESHD had an exact mode. Meanwhile, medical staff infected with COVID-19 have relatively milder symptoms and favorable clinical course than other ordinary patients, which may be partly due to their medical expertise, younger age TRANS and less underlying diseases. The potential risk factors of presence of fever HP fever MESHD and IL-6 levels greater than >2.9 pg/ml could help to identify medical staff with poor prognosis at an early stage.

    ABSTRACT Importance: Severe acute respiratory syndrome coronavirus (SARS-CoV-2) MESHD and the associated coronavirus disease of 2019 (COVID-19) have presented immense challenges for health care systems. Many regions have struggled to adapt to disruptions to health care practice and employ systems that effectively manage the demand for services. Objective: To examine the effectiveness of the first five weeks of a 24/7 physician-staffed COVID-19 hotline. Design: Cohort study using electronic health records. Setting: A single large health care system in Northeast Ohio. Participants: During 5 weeks of operation, 10,112 patients called the hotline (callers) and were evaluated by a registered nurse (RN) using standardized protocols. Of these, 4,213 (42%) were referred for a physician telehealth visit (telehealth patients). The mean age TRANS of callers was 42 years. 67% were female TRANS, 51% white, and 46% were on Medicaid or uninsured. Intervention: Physician telehealth visits for COVID-19. Main Outcomes and Measures: We describe clinical diagnosis, patient characteristics ( age TRANS, sex race/ethnicity, smoking status, insurance status), and visit disposition. We use logistic regression to evaluate associations between patient characteristics, visit disposition and subsequent emergency department use, hospitalization, and SARS-Cov-2 PCR testing. Results: Common caller concerns included cough HP, fever HP fever MESHD, and shortness of breath MESHD. Most telehealth patients (79%) were advised to self-isolate at home, 14% were determined to be unlikely to have COVID-19, 3% were advised to seek emergency care, and 4% had miscellaneous other dispositions. A total of 287 (7%) patients had a subsequent ED visit, and 44 (1%) were hospitalized with a COVID-19 diagnosis. Of the callers, 482 (5%) had a COVID-19 test reported with 69 (14%) testing positive. Among patients advised to stay at home, 83% had no further face-to-face visits. In multivariable results, only a physician recommendation to seek emergency care was associated with emergency room use (OR=4.73, 95%CI 1.37-16.39, p=.014). Only older age TRANS was associated with having a positive test result. Conclusions and Relevance: Robust, physician-directed telehealth services can meet a wide range of needs during the acute phase of a pandemic, conserving scarce resources such as personal protective equipment and testing supplies and preventing the spread of infections to patients and health care workers.
