    Background: The development of thrombotic coagulopathy is frequent in COVID-19 patients, but the timing after infection MESHD, cerebral venous system involvement, treatment and outcome are uncertain.Case Presentation: We report a case of massive cerebral venous thrombosis HP venous thrombosis MESHD occurring in the late phase of COVID-19 infection MESHD. Mild respiratory symptoms, without fever MESHD fever HP, started three weeks before headache MESHD headache HP and acute neurological deficits. She had no dyspnea MESHD dyspnea HP, although she was hypoxic and with typical COVID-19 associated interstitial pneumonia MESHD pneumonia HP. Brain CT scan showed a left parietal hypodense lesion with associated sulcal subarachnoid haemorrhage. CT angiography showed a massive cerebral vein thrombosis MESHD. An asymptomatic TRANS concomitant right internal iliac vein thrombosis MESHD was found. Both cerebral venous thrombosis HP venous thrombosis MESHD and deep venous thrombosis HP venous thrombosis MESHD were effectively treated with unfractionated heparin started on the day of admission, then shifted to low molecular weight heparin, with a favorable clinical course. Nasopharyngel swab, repeated twice, tested negative for SARS-CoV-2. Serological tests SERO confirmed SARS-CoV-2 infection MESHD. Conclusions: Our case supports active surveillance and prevention of thrombotic complications associated with COVID-19, which may affect both peripheral and cerebral venous system. Early initiation of unfractionated heparin may lead to good neurological outcome.

    Background Coronavirus Disease MESHD 2019 (COVID-19) is a rapidly expanding global pandemic resulting in significant morbidity and mortality. COVID-19 patients may present with acute myocardial infarction MESHD myocardial infarction HP (AMI). The aim of this study is to conduct detailed analysis on patients with AMI and COVID-19. Methods We included all patients admitted with AMI and actively known or found to be COVID-19 positive by PCR between the 4th February 2020 and the 11th June 2020 in the State of Qatar. Patients were divided into ST-elevation myocardial infarction MESHD myocardial infarction HP (STEMI) and Non-STE (NSTEMI). Results There were 68 patients (67 men and 1 woman) admitted between the 4th of February 2020 and the 11th of June 2020 with AMI and COVID-19. The mean age TRANS was 49.1, 46 patients had STEMI and 22 had NSTEMI. 38% had diabetes mellitus MESHD diabetes mellitus HP, 31% had hypertension MESHD hypertension HP, 16% were smokers, 13% had dyslipidemia, and 14.7% had prior cardiovascular disease MESHD. Chest pain MESHD Chest pain HP and dyspnea MESHD dyspnea HP were the presenting symptoms in 90% and 12% of patients respectively. Fever MESHD Fever HP (15%) and cough MESHD cough HP (15%) were the most common COVID-19 symptoms, while the majority had no viral symptoms. Thirty-nine (33 STEMI and 6 NSTEMI) patients underwent coronary angiography, 38 of them had significant coronary disease MESHD. Overall in-hospital MACE was low; 1 patient developed stroke MESHD stroke HP and 2 died. Conclusion Contrary to previous small reports, overall in-hospital adverse events were low in this largest cohort of COVID-19 patients presenting with AMI. We hypothesize patient profile including younger age TRANS contributed to these findings. Further studies are required to confirm this observation.

    Background Understanding risk factors for death MESHD in Covid 19 is key to providing good quality clinical care. Due to a paucity of robust evidence, we sought to assess the presenting characteristics of patients with Covid 19 and investigate factors associated with death MESHD. Methods Retrospective analysis of adults TRANS admitted with Covid 19 to Royal Oldham Hospital, UK. Logistic regression modelling was utilised to explore factors predicting death MESHD. Results 470 patients were admitted, of whom 169 (36%) died. The median age TRANS was 71 years (IQR 57 to 82), and 255 (54.3%) were men. The most common comorbidities were hypertension MESHD hypertension HP (n=218, 46.4%), diabetes (n=143, 30.4%) and chronic neurological disease MESHD (n=123, 26.1%). The most frequent complications were acute kidney injury MESHD acute kidney injury HP (n=157, 33.4%) and myocardial injury (n=21, 4.5%). Forty three (9.1%) patients required intubation and ventilation, and 39 (8.3%) received non-invasive ventilation Independent risk factors for death MESHD were increasing age TRANS (OR per 10 year increase above 40 years 1.87, 95% CI 1.57 to 2.27), hypertension MESHD hypertension HP (OR 1.72, 1.10 to 2.70), cancer (OR 2.20, 1.27 to 3.81), platelets <150x103/microlitre (OR 1.93, 1.13 to 3.30), C-reactive protein >100 micrograms/mL (OR 1.68, 1.05 to 2.68), >50% chest radiograph infiltrates, (OR 2.09, 1.16 to 3.77) and acute kidney injury MESHD acute kidney injury HP (OR 2.60, 1.64 to 4.13). There was no independent association between death MESHD and gender TRANS, ethnicity, deprivation level, fever MESHD fever HP, SpO2/FiO2 (oxygen saturation index), lymphopenia MESHD lymphopenia HP or other comorbidities. Conclusions We characterised the first wave of patients with Covid 19 in one of Englands highest incidence areas, determining which factors predict death MESHD. These findings will inform clinical and shared decision making, including the use of respiratory support and therapeutic agents.

    Background Interleukin-6 (IL-6)-mediated hyperinflammation may contribute to the high mortality of coronavirus disease MESHD 2019 (Covid-19). Tocilizumab, an IL-6 receptor blocking monoclonal antibody SERO, has been repurposed for Covid-19, but prospective trials and dose-finding studies in Covid-19 are lacking. Methods We conducted a phase 2 trial of low-dose tocilizumab in hospitalized adult TRANS patients with Covid-19, radiographic pulmonary infiltrate HP, fever MESHD fever HP, and C-reactive protein (CRP) >= 40 mg/L who did not require mechanical ventilation. Dose cohorts were determined by a trial Operations Committee, stratified by CRP and epidemiologic risk factors. A range of doses from 40 to 200 mg (low-dose tocilizumab) was evaluated, with allowance for one repeat dose at 24-48 hours. The primary objective was to assess the relationship of dose to fever MESHD fever HP resolution and CRP response. Outcomes were compared with retrospective controls with Covid-19. Correlative studies evaluating host antibody SERO response were performed in parallel. Findings A total of 32 patients received low-dose tocilizumab. This cohort had improved fever MESHD fever HP resolution (75.0% vs. 34.2%, p = 0.001) and CRP decline (86.2% vs. 14.3%, p < 0.001) in the 24-48 hours following drug administration, as compared to the retrospective controls (N=41). The probabilities of fever MESHD fever HP resolution or CRP decline did not appear to be dose-related in this small study (p=0.80 and p=0.10, respectively). Within the 28-day follow-up, 5 (15.6%) patients died. For patients who recovered, median time to clinical recovery was 3 days (IQR, 2-5). Clinically presumed and/or cultured bacterial superinfections MESHD were reported in 5 (15.6%) patients. Correlative biological studies demonstrated that tocilizumab-treated patients produced anti- SARS-CoV-2 antibodies SERO comparable to controls. Interpretation Low-dose tocilizumab was associated with rapid improvement in clinical and laboratory measures of hyperinflammation in hospitalized patients with Covid-19. Results of this trial and its correlative biological studies provide rationale for a randomized, controlled trial of low-dose tocilizumab in Covid-19.

    BackgroundPoint-of-care ultrasound (POCUS) has a major role in the management of patients with acute hypoxic respiratory and circulatory failure and guides hemodynamic management. There is scarce literature on POCUS assessment characteristics in COVID-19 pneumonia MESHD pneumonia HP with hypoxic respiratory failure HP.MethodsThe study is an observational, prospective, single‐center study conducted in the intensive care unit of Adan General Hospital from May 1st, 2020, to June 25, 2020. The study included adults TRANS suspected to have COVID-19 transferred to the intensive care unit (ICU) with fever MESHD fever HP or suspected respiratory infection MESHD. Patients were transferred to the ICU directly from the ED or general medical wards after reverse transcriptase-polymerase chain reaction (RT-PCR) testing. A certified intensivist in critical care ultrasound who was blinded to the RT-PCR results, if available at the time of examination, performed the lung ultrasound and echocardiology within 12 hours of the patient’s admission to the ICU. We calculated the E/e’, E/A ratio, left ventricular ejection fraction EF, IVC diameter, RV size and systolic function. We performed ultrasound in 12 chest areas.ResultsOf 92 patients with suspected COVID-19 pneumonia MESHD pneumonia HP, 77 (84%) cases were confirmed TRANS. The median age TRANS of the patients was 53 (82-36) years, and 71 (77%) were men.In the group of patients with confirmed COVID-19 pneumonia MESHD pneumonia HP, echocardiographic findings showed normal E/e’, deceleration time (DT), and transmittal E/A ratio in comparison to the non-COVID19 patients (P .001 for both). The IVC diameter was <2 cm with > 50% collapsibility in 62 (81%) patients with COVID-19 pneumonia MESHD pneumonia HP; a diameter of > 2 cm and < 50% collapsibility in all patients, with a P value of 0.001, was detected among those with non-COVID-19 pneumonia MESHD pneumonia HP. There were 3 cases of myocarditis MESHD myocarditis HP with poor EF (5.5%), severe RV dysfunction was seen in 9 cases (11.6%), and 3 cases showed RV thrombus.Chest US revealed four signs suggestive of COVID-19 pneumonia MESHD pneumonia HP in 77 patients (98.6%) ( sensitivity SERO 96.9%, CI 85%‐99.5%) when compared with RT-PCR results.ConclusionPOCUS plays an important role in bedside diagnosis, hemodynamic assessment and management of patients with acute hypoxic respiratory and circulatory failure in patients with COVID-19 pneumonia MESHD pneumonia HP.

    Currently, the COVID‐19 has directly affected the millions of humans lives. The symptoms of the disease MESHD involving fever MESHD fever HP, malaise, chest infection MESHD, and breathing difficulties, were identified, and its existence is continuously becoming restructured. The World Health Organization (WHO) had mentioned the wide diagnostics test besides COVID-19 that would also assist medical facilities to recognize infectious diseases as well MESHD as currently focusing efficiently on preventing and afterward defeating this viral disease MESHD. The infection MESHD is usually transmitted among human beings in direct contact, greatest through the liquid bubbles generated through cough MESHD cough HP, sneeze MESHD sneeze HP, or speaking. This paper reviews the COVID 19 pandemic, its history, current updates, contact tracing TRANS applications, and use of emerging technologies like the Internet of Things (IoT) and Blockchain for stopping the spreading and provide service online to the patient from a distance.

    Background: SARS-CoV-2 causes COVID-19 disease MESHD. It was identified in December 2019 and rapidly evolved into a pandemic. During the outbreak of COVID-19, researches demonstrated its effect on many systems, including the nervous system. In our clinic, we have reported an impact of SARS-CoV-2, causing the ischaemic stroke MESHD stroke HP.Case Report: A 62-year-old Sudanese male TRANS with some comorbidities brought to the A&E with fever MESHD fever HP, chest symptoms, and acute evolving left-sided hemiplegia MESHD hemiplegia HP power grade 0/5 MRCS with left upper motor neuron facial palsy HP. Investigations: CT brain: right middle cerebral artery MCA infarction MESHD. CT- chest: bilateral ground-glass appearance. COVID-19 Test was positive. elevated D-dimer and C-reactive protein.Discussion: A retrospective study of data from the COVID-19 outbreak in China showed that the incidence of stroke MESHD stroke HP among hospitalized patients was approximately 5%. The fact that COVID-19 is an acute inflammatory condition associated with an increased incidence of fatty plaques formation, injury of the vascular wall, and hypercoagulability HP, causing brain infarct can be a reasonable hypothesis.ConclusionPatients with COVID-19 are at increased risk of thrombo-embolization, leading to arterial and venous cerebrovascular accident. This case report enhances the importance of further studies to clarify the relationship between stroke MESHD stroke HP and COVID-19.

    Background: COVID-19 has heterogeneous manifestations, though one of the most common symptoms is a sudden loss of smell ( anosmia HP or hyposmia HP). We investigated whether olfactory loss is a reliable predictor of COVID-19. Methods: This preregistered, cross-sectional study used a crowdsourced questionnaire in 23 languages to assess symptoms in individuals self-reporting recent respiratory illness. We quantified changes in chemosensory abilities during the course of the respiratory illness using 0-100 visual analog scales (VAS) for participants reporting a positive (C19+; n=4148) or negative (C19-; n=546) COVID-19 laboratory test outcome. Logistic regression models identified singular and cumulative predictors of COVID-19 status and post-COVID-19 olfactory recovery. Results: Both C19+ and C19- groups exhibited smell loss, but it was significantly larger in C19+ participants (mean{+/-}SD, C19+: -82.5{+/-}27.2 points; C19-: -59.8{+/-}37.7). Smell loss during illness was the best predictor of COVID-19 in both single and cumulative feature models (ROC AUC=0.72), with additional features providing no significant model improvement. VAS ratings of smell loss were more predictive than binary chemosensory yes/no-questions or other cardinal symptoms, such as fever MESHD fever HP or cough MESHD cough HP. Olfactory recovery within 40 days was reported for ~50% of participants and was best predicted by time since illness onset. Conclusions: As smell loss is the best predictor of COVID-19, we developed the ODoR-19 tool, a 0-10 scale to screen for recent olfactory loss. Numeric ratings [≤]2 indicate high odds of symptomatic COVID-19 (10

    Background Confirmed COVID-19 cases have been reported in 213 countries and regions and as of 12 July 2020, over 12 million cases, with 561617 deaths MESHD have been reported worldwide. The number of cases changes quickly and varies depending upon which source you use to track, so in the current epidemiological context, the early recognition is critical for the rapid identification of suspected cases (with SARS-CoV-2 infection MESHD-like symptoms and signs MESHD) to be immediately subjected to quarantine measures. Although surveys are widely used for identifying COVID-19 cases, outcomes and associated risks, no validated epidemiological tool exists for surveying SARS-CoV-2 infection MESHD in the population so far. Methods Our study is the phase II of the EPICOVID19 national survey, launched in April 2020 including a national convenience sample of 201121 adults TRANS, who voluntarily filled the EPICOVID19 questionnaire. The phase II questionnaire was mailed to all subjects who underwent tests for COVID-19 by nasopharyngeal swab (NPS) and who accepted to be involved in the second phase of the study, focused on the results reported for NPS and/or serological IgG/IgM tests. We evaluated the capability of the self-reported symptoms collected through the EPICOVID19 questionnaire to discriminate the COVID-19 among symptomatic subjects, in order to identify possible cases to undergo instrumental measurements and clinical examinations. We defined a method for the identification of a total score and validated it with reference to the serological and molecular clinical diagnosis, using four standard steps: identification of critical factors, confirmation of presence of latent variable, development of optimal scoring algorithm and validation of the scoring algorithm. Findings 2703 subjects [66% response rate] completed the Phase II questionnaire. Of 2703 individuals, 694 (25.7%) were NPS(+) and of these 84 (12.1% of the 694 NPS(+)) were asymptomatic TRANS. In the individuals who performed serological testing SERO, of the 472 who did IgG(+) and 421 who did IgM(+), 22.9% and 11.6% tested positive, respectively. Among IgG(+) 1 of 108 subjects was asymptomatic TRANS (0.9%) while 5/49 subjects among IgM(+) were asymptomatic TRANS (10.2%). Compared with NPS(-), among NPS(+) subjects there was a higher rate for Fever MESHD Fever HP (421 [60.7%] vs 391[19.5% ]; p<0.0001), Loss of Taste and/or Smell (365 [52.6%] vs 239 [11.9% ]; p<0.0001) and Cough MESHD Cough HP (352 [50.7%] vs 580 [28.9% ]; p<0.0001). Also for other symptoms the frequencies were significantly higher in NPS(+) subjects than in NPS(-) ones (p<0.001). Among groups with serological tests SERO, the symptoms with higher percentages in the subjects IgG(+) were Fever MESHD Fever HP (65 [60.2%] vs 43[11.8% ]; p<0.0001) and Pain MESHD Pain HP in muscles, bones, joints (73 [67.6%] vs 71 [19.5% ]; p<0.0001). For the COVID-19 self-reported symptoms items, exploratory (proportion variance explained [89.9%]) and confirmatory factor analysis results (SMSR 0.072; RMSEA 0.052) highlights the presence of one latent variable (factor) underlying the symptoms. We define the one-factor solution as EPICOVID19 diagnostic scale and optimal score for each items was identified: Respiratory problems (1.03), Chest pain MESHD Chest pain HP (1.07), Loss of Taste and/or Smell (0.97) and Tachycardia MESHD Tachycardia HP ( palpitations HP) (1.05) were the most important symptoms. The cut-off score was 2.56 ( Sensitivity SERO 76.56%; Specificity 68.24%) in NPS(+) and 2.59 (Se 80.37; Sp 80.17) in IgG(+) subjects.

    SARS-CoV-2 has driven a pandemic crisis. Serological surveys have been conducted to establish prevalence SERO for covid-19 antibody SERO in various cohorts and communities. However, the prevalence SERO among healthcare workers is still being analyzed. The present study reports on initial sero-surveillance conducted on healthcare workers at a regional hospital system in Orange County, California, during May and June, 2020. Study participants were recruited from the entire hospital employee workforce and the independent medical staff. Data were collected for job title, location, covid-19 symptoms, a PCR test history, travel TRANS record since January 2020, and existence of household contacts TRANS with covid-19. A blood SERO sample was collected from each subject for serum SERO analysis for IgG antibodies SERO to SARS-CoV-2. Of 3,013 tested individuals, a total 2,932 were included in the analysis due to some missing data. Observed prevalence SERO of 1.06% (31 antibody SERO positive cases), adjusted prevalence SERO of 1.13% for test sensitivity SERO and specificity were identified. Significant group differences between positive vs. negative were observed for age TRANS (z = 2.65, p = .008), race (p = .037), presence of fever MESHD fever HP (p < .001) and loss of smell (p < .001). Possible explanation for this low prevalence SERO includes a relatively low local geographic community prevalence SERO (~4.4%) at the time of testing, the hospital's timely procurement of personal protective equipment, rigorous employee education, patient triage and treatment protocol development and implementation. In addition, possible greater presence of cross-reactive adaptive T cell mediated immunity in healthcare workers vs. the general population may have contributed. Determining antibody SERO prevalence SERO in front-line workers, and duration of antibody SERO presence may help stratify the workforce for risk, establish better health place policies and procedures, and potentially better mitigate transmission TRANS.
