    Background. Healthcare workers (HCW) are at increased risk of being infected with SARS-CoV-2, yet limited information is available on risk factors of infection MESHD. Methods. We pooled data on occupational surveillance of 10,654 HCW who were tested for SARS-CoV-2 infection MESHD in six Italian centers. Information was available on demographics, job title, department of employment, source of exposure, use of personal protective equipment (PPE), and COVID-19-related symptoms. We fitted multivariable logistic regression models to calculate odds ratios (OR) and 95% confidence intervals (CI). Findings. The prevalence SERO of infection MESHD varied across centers and ranged from 3.0% to 22.0%, being strongly correlated with that of the respective areas. Women were at lower risk of infection TRANS risk of infection TRANS infection MESHD compared to men. Fever MESHD Fever HP, cough MESHD cough HP, dyspnea MESHD dyspnea HP and malaise were the symptoms most strongly associated with infection MESHD, together with anosmia HP and ageusia MESHD. No differences in the risk of infection TRANS risk of infection TRANS infection MESHD were detected between job titles, or working in a COVID-19 designated department. Reported contact with a patient inside or outside the workplace was a risk factor. Use of a mask was strongly protective against risk of infection TRANS risk of infection TRANS infection MESHD as was use of gloves. The use of a mask by the source of exposure (patient or colleague) had an independent effect in reducing infection MESHD infection risk TRANS infection risk TRANS risk.

    Background Access to molecular diagnosis was limited out-of-hospital in France during the 2020 coronavirus disease MESHD 2019 (COVID-19) epidemic. This study describes the evolution of COVID-19 outbreak in a nursing home in absence of molecular diagnosis. Methods A monocentric prospective study was conducted in a French nursing home from March 17th, 2020 to June 11th, 2020. Because of lack of molecular tests for severe acute respiratory syndrome MESHD 2 (SARS-Cov2) infection MESHD, probable COVID-19 cases were early identified considering only respiratory and not-respiratory symptoms and therefore preventing measures and treatments were enforced. Once available, serology tests were performed at the end of the study.A chronologic description of new cases and deaths MESHD was made together with a description of COVID-19 symptoms. Data about personal characteristics and treatments were collected and the following comparisons were performed: i) probable COVID-19 cases vs asymptomatic TRANS residents; ii) SARS-Cov2 seropositive residents vs seronegative residents. Results Overall, 32/66 (48.5%) residents and 19/39 (48.7%) members of health-care personnel were classified as probable COVID-19 cases. A total of 34/61 (55.7%) tested residents resulted seropositive. Death MESHD occurred in 4/66 (6%) residents. Diagnosis according to symptoms had 65% of sensitivity SERO, 78% of specificity, 79% of positive predictive value SERO and 64% of negative predictive value SERO.In resident population, the following symptoms were registered: 15/32 (46.8%) lymphopenia MESHD lymphopenia HP, 15/32 (46.8%) fever MESHD fever HP, 8/32 (25%) fatigue MESHD fatigue HP, 8/32 (25%) cough MESHD cough HP, 6/32 (18.8%) diarrhoea, 4/32 (12.5%) severe respiratory distress HP requiring oxygen therapy, 4/32 (12.5%) fall HP, 3/32 (9.4%) conjunctivitis MESHD conjunctivitis HP, 2/32 (6.3%) abnormal pulmonary noise at chest examination and 2/32 (6,25%) abdominal pain MESHD abdominal pain HP. Probable COVID-19 cases were older (81.3 vs 74.9; p=0.007) and they had higher prevalence SERO of atrial fibrillation MESHD atrial fibrillation HP (8/32, 25% vs 2/34, 12%; p=0.030); insulin treatment (4/34, 12% vs 0, 0%; p=0.033) and positive SARS-Cov2 serology (22/32, 69% vs 12/34, 35%; p=0.001) than asymptomatic TRANS residents. Seropositive residents had lower prevalence SERO of diabetes (4/34, 12% vs 9/27, 33%; p=0.041) and angiotensin-converting-enzyme inhibitors’ intake (1/34, 1% vs 5/27, 19%; p=0.042). Conclusions During SARS-Cov2 epidemic, early detection of respiratory and not-respiratory symptoms allowed to enforce extraordinary measures. They achieved limiting contagion and deaths MESHD among nursing home residents, even in absence of molecular diagnosis.

    Background: Coronavirus disease MESHD 2019 (COVID-19) caused by SARS-CoV-2 has become a global pandemic, and those developing critically ill conditions have been reported to have mortality in the range of 39% to 61%. Due to the lack of definitive treatments, mechanical ventilation and supportive oxygenation therapy are key management strategies for the survival of patients with acute respiratory distress HP syndrome MESHD (ARDS). Optimizing oxygenation therapy is mandatory to treat patients with severe respiratory failure HP, to sufficiently compensate for the oxygen (O2) demand. We experienced a case of severe ARDS due to COVID-19 successfully treated with extracorporeal membrane oxygenation (ECMO) after increasing oxygen delivery according to O2 consumption measurement by indirect calorimetryCase Presentation: A 29-year-old obese but otherwise healthy man was hospitalized for treatment of COVID-19 pneumonia MESHD pneumonia HP presenting with a 4-day history of persisting cough MESHD cough HP, high fever MESHD fever HP, and dyspnea MESHD dyspnea HP. Mechanical ventilation, nitric oxide inhalation, and prone positioning were initiated in the ICU against severe respiratory dysfunction. Indirect calorimetry on the 3rd and 6th ICU days revealed persistent elevation of oxygen consumption (VO2) of 380 mL/min. Veno-venous ECMO was initiated on the 7th ICU day after further deterioration of respiratory failure HP. Periodic events of SpO2 decline due to effortful breathing was not resolved by neuromuscular blockade in attempt to reduce O2 consumption. Increasing the ECMO flow induced hemolysis MESHD and hyperkalemia MESHD hyperkalemia HP despite the use of large bore cannulas and ECMO circuit free of clots and defects. The hemoglobin management level was elevated from 10 g/dL to 13 g/dL to increase blood SERO oxygen capacity, enabling the reduction of ECMO flow while attenuating respiratory effort and maintaining SpO2. Lung protective ventilation strategy and prone positioning were continued for successful weaning from ECMO on the 16th ICU day, and the ventilator on the 18th ICU day.Conclusion: The present case of severe ARDS due to COVID-19 was successfully treated with ECMO. Enhancing oxygen delivery was crucial to compensate for the elevated O2 demand. Measuring O2 consumption by indirect calorimetry can elucidate the oxygen demand for optimizing the oxygenation therapy for successful management and survival of critically ill COVID-19 patients.

    Background: The COVID 19 pandemic has been creating a panic and distressing situations among the entire population globally including Nepal. No study has been conducted assessing the psychological impact of this pandemic on the general public in Nepal. The objective of this study is to assess the mental health status during COVID 19 outbreak and explore the potential influencing factors among the population attending the hospital fever MESHD fever HP clinics with COVID 19 symptoms. Methods: A cross sectional survey was conducted between May to June, 2020 with a sample of 645 participants aged TRANS 18 and above in 26 hospitals across Nepal. Telephone interviews were conducted using a semi-structured questionnaire along with a validated psychometric tool, the Depression, Anxiety HP and Stress (DASS21) scale. The metrics and scores of symptoms and their severity were created and analyzed. Multivariate logistic regression was used to determine the association of potential covariates with outcome variables. Results: The prevalence SERO of anxiety HP, depression and stress were 14%, 7% and 5% respectively. Participants from Bagmati province reported higher level of anxiety HP (OR 3.87, 95% CI 1.42 10.59), while stress (OR 4.78, 95% CI 1.09 21.29) and depressive symptoms (OR 3.37, 95% CI 1.10 10.35) observed higher among the participants in Province 1. Women were more at risk of anxiety HP (OR 4.26, 95% CI 2.21 8.20) and depression (2.75, 95% CI 1.16 6.51) than men. Similarly, people with primary level education found more prone to all factors, stress (OR 20.35, 95% CI 2.06 201.19), anxiety HP (OR 3.10, 95% CI 1.24 7.91), and depression (OR 4.41, 95% CI 1.29 15.07). More farmers than labors showed higher odds (OR 2.25, 95% CI 1.01 5.01) for anxiety HP, while individuals surveyed who reported their health status as poor-had higher odds (OR 5.95, 95% CI 1.08 32.68) for depression. Also, people currently living in rented houses reported more stress (OR 3.11, 95% CI 1.07 9.05) and those living far from family reported higher rates of depressive symptoms (OR 3.57, 95% CI 1.01 12.58). Conclusion: The study identified increased prevalence SERO of stress, anxiety HP and depressive symptoms during the initial stage of COVID 19 pandemic in Nepal. Considering the findings, there is urgent need to develop and implement appropriate community-based mental health programs targeting individuals who have had COVID 19 symptoms and who are prone to develop adverse mental health outcomes.

    Objective: Public cooperation to practice preventive health behaviours is essential to manage the transmission TRANS of infectious diseases MESHD such as COVID-19. We aimed to investigate beliefs about COVID-19 diagnosis, transmission TRANS and prevention that have the potential to impact the uptake of recommended public health strategies. Design: An online cross-sectional survey conducted May 8 to May 11 2020. Participants: A national sample of 1500 Australian adults TRANS with representative quotas for age TRANS and gender TRANS provided by online panel provider. Main outcome measure: Proportion of participants with correct/incorrect knowledge of COVID-19 preventive behaviours and reasons for misconceptions. Results: Of the 1802 potential participants contacted, 289 were excluded, 13 declined, and 1500 participated in the survey (response rate 83%). Most participants correctly identified washing your hands regularly with soap and water (92%) and staying at least 1.5m away from others (90%) could help prevent COVID-19. Over 40% (incorrectly) considered wearing gloves outside of the home would prevent them contracting COVID-19. Views about face masks were divided. Only 66% of participants correctly identified that regular use of antibiotics would not prevent COVID-19. Most participants (90%) identified fever MESHD fever HP, fatigue MESHD fatigue HP and cough MESHD cough HP as indicators of COVID-19. However, 42% of participants thought that being unable to hold your breath for 10 seconds without coughing MESHD coughing HP was an indicator of having the virus. The most frequently reported sources of COVID-19 information were commercial television channels (56%), the Australian Broadcasting Corporation (43%), and the Australian Government COVID-19 information app (31%). Conclusions: Public messaging about hand hygiene and physical distancing to prevent transmission TRANS appear to have been effective. However, there are clear, identified barriers for many individuals that have the potential to impede uptake or maintenance of these behaviours in the long-term. Currently these non-drug interventions are our only effective strategy to combat this pandemic. Ensuring ongoing adherence to is critical.

    BACKGROUND: Symptoms of SARS-CoV-2 infection MESHD in children TRANS are nonspecific and shared with other common acute viral illnesses ( fever MESHD fever HP, respiratory or gastrointestinal symptoms, and cutaneous signs), thus making clinical differential diagnosis tricky. In Italy, first line management of pediatric care is handed over to Primary Care Pediatricians (PCPs), who were not allowed to directly perform diagnostic tests during the recent COVID-19 outbreak. Without a confirmatory diagnosis, PCPs could only collect information on ''COVID-19 like symptoms'' rather than identify typical COVID-19 symptoms. AIM: To evaluate the prevalence SERO of COVID-19 like symptoms in outpatient children TRANS, during Italian lockdown. To provide PCPs a risk score to be used in clinical practice during the differential diagnosis process. METHODS: A survey was submitted to 50 PCPs (assisting 47,500 children TRANS) from 7 different Italian regions between the 4th of March and the 23rd of May 2020 (total and partial lockdown period). COVID-19 like symptoms in the assisted children TRANS were recorded, as well as presence of confirmed/suspected cases in children TRANS's families, which was taken as proxy of COVID-19. Multivariable logistic regression was accomplished to estimate the risk of having suspected/ confirmed cases TRANS in families, considering symptoms as potential determinants. RESULTS: 2,300 children TRANS (4.8% of overall survey population) fell HP ill with COVID-19 like symptoms, 3.1% and 1.7% during total and partial lockdown period respectively. The concurrent presence of fatigue MESHD fatigue HP, cough MESHD cough HP, and diarrhea MESHD diarrhea HP in children TRANS, in absence of sore throat/ earache MESHD and abnormal skin signs, represents the maximum risk level of having a suspected/ confirmed case TRANS of COVID-19 at home. CONCLUSIONS: The percentage of children TRANS presenting COVID-19 like symptoms at home has been remarkable also during the total lockdown period. The present study identified a pattern of symptoms which could help, in a cost-effective perspective, PCPs in daily clinical practice to define priorities in addressing children TRANS to the proper diagnostic procedure.

    BACKGROUND: Despite the significant morbidity and mortality caused by the 2019 novel coronavirus disease MESHD (COVID-19), our understanding of basic disease MESHD epidemiology remains limited. This study aimed to describe key patient characteristics, comorbidities, treatments, and outcomes of a large U.S.-based cohort of patients hospitalized with COVD-19 using electronic health records (EHR). METHODS: We identified patients in the Optum De-identified COVID-19 EHR database who had laboratory-confirmed COVID-19 or a presumptive diagnosis between 20 February 2020 and 6 June 2020. We included hospitalizations that occurred 7 days prior to, or within 21 days after, COVID-19 diagnosis. Among hospitalized patients we describe the following: vital statistics and laboratory results on admission, relevant comorbidities (using diagnostic, procedural, and revenue codes), medications (NDC, HCPC codes), ventilation, intensive care unit (ICU) stay, length of stay (LOS), and mortality. RESULTS: We identified 76,819 patients diagnosed with COVID-19, 16,780 of whom met inclusion criteria for COVID-related hospitalization. Over half the cohort was over age TRANS 50 (74.5%), overweight MESHD overweight HP or obese (77.2%), or had hypertension MESHD hypertension HP (58.1%). At admission, 30.3% of patients presented with fever MESHD fever HP (>38C) and 32.3% had low oxygen saturation (<90%). Among the 16,099 patients with complete hospital records, we observed that 58.9% had hypoxia MESHD, 23.4% had an ICU stay during hospitalization, 18.1% were ventilated, and 16.2% died. The median LOS was 6 days (IQR: 4, 11). CONCLUSIONS: To our knowledge, this is the largest descriptive study of patients hospitalized with COVID-19 in the United States. We report summary statistics of key clinical outcomes that provide insights to better understand COVID-19 disease MESHD epidemiology.

    This study aimed to summarize the existing literature on severe acute respiratory syndrome MESHD coronavirus 2 (SARS-CoV-2) infection in newborns to clarify the clinical features and outcomes of neonates with COVID-19. A systematic search was performed in PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data, and VIP databases from January 1, 2019 to April 30, 2020. The references of relevant studies were also searched. A descriptive summary was organized by aspects of clinical presentations (symptoms, laboratory examinations, and imaging) and outcomes. We identified 14 studies reporting 18 newborns with COVID-19. The most common clinical manifestations were fever MESHD fever HP (62.5%), shortness of breath (50.0%), diarrhea MESHD diarrhea HP/ vomiting MESHD vomiting HP/feeding intolerance(43.8%), cough MESHD cough HP (37.5%), dyspnea MESHD dyspnea HP (25.0%), and nasal congestion/runny nose/ sneeze MESHD sneeze HP(25.0%). Atypical symptoms included jaundice MESHD jaundice HP and convulsion. Lymphocyte numbers decreased in 5 cases, and radiographic findings were likely to show pneumonia MESHD pneumonia HP. All newborns recovered and discharged from the hospital, and there was no death MESHD.Conclusion: Clinical symptoms of neonatal SARS-CoV-2 infection MESHD are atypical, most of them are mild. Up to now, the prognosis of newborns is good, and there is no death MESHD. Intrauterine vertical transmission TRANS is possible, but confirmed evidence is still lacking. The Long-term follow-up of potential influences of SARS-CoV-2 infection MESHD on neonates need further exploration.

    On the basis of Covid-19-induced pulmonary pathological and vascular changes, we hypothesized that the anti-VEGF drug bevacizumab might be beneficial for treating Covid-19 patients. We recruited 26 patients from 2-centers (China and Italy) with confirmed severe Covid-19, with respiratory rate [≥]30 times/min, oxygen saturation [≤]93% with ambient air, or partial arterial oxygen pressure to fraction of inspiration O2 ratio (PaO2/FiO2) >100mmHg and [≤]300 mmHg, and diffuse pneumonia MESHD pneumonia HP confirmed by chest radiological imaging. This trial was conducted from Feb 15 to April 5, 2020, and followed up for 28 days. Relative to comparable control patients with severe Covid-19 admitted in the same centers, bevacizumab showed clinical efficacy by improving oxygenation and shortening oxygen-support duration. Among 26 hospitalized patients with severe Covid-19 (median age TRANS, 62 years, 20 [77%] males TRANS), bevacizumab plus standard care markedly improved the PaO2/FiO2 ratios at days 1 and 7 (elevated values, day 1, 50.5 [4.0,119.0], p<0.001; day 7, 111.0 [85.0,165.0], p<0.001). By day 28, 24 (92%) patients showed improvement in oxygen-support status, 17 (65%) patients were discharged, and none showed worsen oxygen-support status nor died. Significant reduction of lesion areas and ratios were shown in chest CT or X-ray analysis within 7 days. Of 14 patients with fever MESHD fever HP, body temperature normalized within 72 hours in 13 (93%) patients. Lymphocyte counts in peripheral blood SERO were significantly increased and CRP levels were markedly decreased as shown in available data. Our findings suggested bevacizumab plus standard care was highly beneficial for treating patients with severe Covid-19. Clinical efficacy of bevacizumab warrants double blind, randomized, placebo-controlled trials.

    Objective: To evaluate the association of olfactory dysfunction (OD) with hospitalization for COVID-19. Study Design: Multi-center cohort study. Setting: Emergency MESHD departments of thirteen COVID-19-designed hospitals in Kurdistan province, Iran. Subjects and Methods: Patients presenting with flu-like symptoms who tested positive by RT-PCR for COVID-19 between May 1st and 31st, 2020. At the time of presentation and enrollment, patients were asked about the presence of OD, fever MESHD fever HP, cough MESHD cough HP, shortness of breath, headache MESHD headache HP, rhinorrhea HP and sore throat. The severity of OD was assessed on an 11-point scale from 0 (none) to 10 ( anosmia HP). Patients were either hospitalized or sent home for outpatient care based on standardized criteria. Results: Of 203 patients, who presented at a mean of 6 days into the COVID-19 disease MESHD course, 25 patients (12.3%) had new OD and 138 patients (68.0%) were admitted for their COVID-19. Patients admitted for COVID-19 had a higher prevalence SERO of all symptoms assessed, including OD (p<0.05 in all cases), and OD identified admitted patients with 84.0% sensitivity SERO and 34.3% specificity. On univariate logistic regression, hospitalization was associated with OD (odds ratio [OR] = 2.47, 95%CI: 1.085-6.911, p=0.049). However, hospitalization for COVID-19 was not associated with OD (OR=3.22, 95% CI: 0.57-18.31, p=0.188) after controlling for confounding demographics and comorbidities. Conclusion: OD may be associated with hospitalization for (and therefore more severe) COVID-19. However, this association between OD and COVID-19 severity is more likely driven by patient characteristics linked to OD, such as greater numbers of COVID-19 symptoms experienced or high-risk comorbidities.
