    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 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.

    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.

    Background: Coronavirus Disease MESHD 2019 (COVID-19) is a disease caused by infection with Severe HP infection with Severe MESHD Severe Acute Respiratory Syndrome Coronavirus 2 MESHD (SARS-CoV-2), which commonly presents with symptoms including fever HP fever MESHD, cough HP cough MESHD, and dyspnea HP dyspnea MESHD. More recently, however, some patients have tested positive for COVID-19 after developing gastrointestinal ( GI MESHD) symptoms either solely or in conjunction with respiratory symptoms. This may be due to SARS-CoV-2 infection MESHD of the GI MESHD tract. In patients with chronic GI illnesses MESHD, COVID-19 may initially present as a flare of their underlying GI MESHD conditions as viruses have historically been implicated in exacerbations of GI disorders MESHD, including gastroparesis HP gastroparesis MESHD. Case presentation: We report a case of a 37 year-old female TRANS with a history of diabetic gastroparesis MESHD gastroparesis HP who presented to the Emergency Department (ED) in a gastroparesis HP gastroparesis MESHD flare. Her symptoms in the ED failed to improve with fluids and anti-emetic medications. After developing a fever HP fever MESHD, she was tested and found to be positive for COVID-19.Conclusion: To our knowledge, at the present time, this is the first report of a patient with COVID-19 presenting with signs and symptoms of a gastroparesis HP gastroparesis MESHD flare. This case illustrates that patients with underlying GI disorders MESHD, such as gastroparesis HP gastroparesis MESHD, may have SARS-CoV-2 infections MESHD that present as an exacerbation of their underlying disorder. Initial presentation of these patients manifesting as a flare of their chronic GI disease MESHD, more severe than usual, should prompt an index of suspicion for COVID-19.

    Background: Since December 2019, the outbreak of COVID-19 has spread quickly and thumped many countries and regions. The epidemic of central China was under the spotlight and attracted much more attentions. However, there are few reports describing COVID-19 patients in the regions outside of Wuhan, which are undergoing the change from sporadic imported cases to community-acquired transmission TRANS.Methods: The electronic medical records of 74 laboratory-confirmed patients of COVID-19 were retrospectively reviewed and analyzed. Their epidemiological, demographic, clinical and radiological characteristics were systematically summarized. The difference between severe patients and non-severe patients were also analyzed statistically.Results: The 74 COVID-19 patients were composed of 4 (5.4%) mild patients, 56 (75.7%) common patients, 13 (17.6%) severe patients and 1 (1.4%) critical patient. 43 were male TRANS, and 31 were female TRANS, with the average age TRANS 48.1±17.5. No significant difference of susceptibility was observed between genders TRANS, and almost people with all age TRANS were susceptible to SARS-CoV-2 infection MESHD. Before Jan 26, only imported sporadic cases were observed. However, from that day onward, family cluster infection MESHD cases increased dramatically, up to 70.3% (52/74), which were mainly from 15 family. The incubation period TRANS spanned from 0 to 19 days, with the median 5, and 81.4% had symptom onset TRANS within 7 days. At admission, 31.1% of patients had underlying diseases MESHD and the most common underlying diseases were hypertension HP hypertension MESHD (13.5%) and diabetes MESHD (5.4%). The most common symptoms were fever HP fever MESHD (90.5%), cough HP (75.7%), fatigue HP fatigue MESHD (36.5%) and chest distress (32.4%). 36.5% and 16.2% of patients had leukopenia HP leukopenia MESHD and lymphocytopenia MESHD. 43.2% of patients had increased C reactive protein (CRP), and 40.5% had higher erythrocyte sedimentation rate (ESR) and 21.6% had higher calcitonin. 74.3% of patients had obvious lesions in both lung lobes MESHD and 56.8% of lesions manifested as ground glass opacity. Compared with non-severe group, the severe/critical group were significantly older and had more underlying diseases. After treatment, all patients improved and were discharged. No medical professional infection MESHD and death case were reported.Conclusion: The epidemic of COVID-19 in Nanjing were mainly caused by family cluster infection MESHD. The entire prevalence SERO and illness were much milder than those of Wuhan. The disease of COVID-19 could be controlled and cured.
