    BackgroundSevere coronavirus disease MESHD-19 (COVID-19) presents with progressive dyspnea MESHD dyspnea HP, which results from acute lung inflammatory edema MESHD edema HP leading to hypoxia MESHD. As with other infectious diseases MESHD that affect the respiratory tract, asthma MESHD asthma HP has been cited as a potential risk factor for severe COVID-19. However, conflicting results have been published over the last few months and the putative association between these two diseases MESHD is still unproven.MethodsHere, we systematically reviewed all reports on COVID-19 published since its emergence in December 2019 to May 18, 2020, looking into the description of asthma MESHD asthma HP as a premorbid condition, which could indicate its potential involvement in disease progression MESHD.ResultsWe found 169 articles describing the clinical characteristics of 36,072 patients diagnosed with COVID-19. Asthma MESHD Asthma HP was reported as a premorbid condition in only 655 patients accounting for 1.8% of all patients.ConclusionsAs the global prevalence SERO of asthma MESHD asthma HP is 4.4%, we conclude that either asthma MESHD asthma HP is not a premorbid condition that contributes to the development of COVID-19 or clinicians and researchers are not accurately describing the premorbidities in COVID-19 patients.

    Background: Prevalence SERO and outcomes of Coronavirus Disease MESHD (COVID)-19 in relation to immunomodulatory medications are still unknown. The aim of the study is to investigate the impact of glucocorticoids and immunosuppressive agents on COVID-19 in a large cohort of patients with chronic immune-mediated inflammatory arthritis MESHD arthritis HP.Methods: The study was conducted in the arthritis MESHD arthritis HP outpatient clinic at two large Academic Hospitals in the COVID-19 most endemic area of Northern Italy (Lombardy). We circulated a cross-sectional survey exploring the prevalence SERO of Severe Acute Respiratory Syndrome MESHD-Coronavirus-2 nasopharyngeal swab positivity and the occurrence of acute respiratory illness ( fever MESHD fever HP and/or cough MESHD cough HP and/or dyspnea MESHD dyspnea HP), administered face-to-face or by phone to consecutive patients from 25th February to 20th April 2020. COVID-19 cases were defined as confirmed or highly suspicious according to the World Health Organization criteria. The impact of medications on COVID-19 incidence was evaluated. Results: The study population included 2050 adults TRANS with chronic inflammatory arthritis MESHD arthritis HP receiving glucocorticoids, conventional-synthetic (cs), or targeted-synthetic/biological (ts/b) disease MESHD-modifying drugs (DMARDs). Laboratory-confirmed COVID-19 and highly suspicious infection MESHD were recorded in 1.1% and 1.4% of the population, respectively. Treatment with glucocorticoids was independently associated with increased risk of COVID-19 (adjusted OR [95% CI] ranging from 1.23 [1.04-1.44] to 3.20 [1.97-5.18] depending on the definition used). Conversely, patients treated with ts/bDMARDs were at reduced risk (adjusted OR ranging from 0.46 [0.18-1.21] to 0.47 [0.46-0.48]). No independent effects of csDMARDs were observed.Conclusions: During the COVID-19 outbreak, treatment with immunomodulatory medications appears safe. Conversely, glucocorticoids, even at low-dose, may confer increased risk of infection TRANS risk of infection TRANS infection MESHD.Trial registration:  retrospectively registered

    Objectives: Coronavirus disease MESHD 2019 (COVID-19) can present with a variety of symptoms. Severity of the disease MESHD may be associated with several factors. Here, we review clinical features of COVID-19 patients with different severities.Methods: This cross-sectional study was performed in Imam Reza hospital, Mashhad, Iran, during February-April 2020. COVID-19 patients with typical computed tomography (CT) patterns and/or positive reverse-transcriptase polymerase chain reaction (RT-PCR) were included. The patients were classified into three groups of moderate, severe, and critical based on disease MESHD severity. Demographic, clinical, laboratory, and radiologic findings were collected and compared. P<0.05 was considered statistically significant.Results: Overall, 200 patients with mean age TRANS of 69.75±6.39 years, of whom 82 (41%) were female TRANS were studied. Disease MESHD was severe/critical in the majority of patients (167, 83.5%). Disease MESHD severity was significantly associated with age TRANS, malignant comorbidities, dyspnea MESHD dyspnea HP, nausea MESHD nausea/vomiting HP/ vomiting MESHD, confusion MESHD confusion HP, respiratory rate, pulse rate, O2 saturation, extent of CT involvement, serum SERO C-reactive protein (CRP), pH, pO2, and aspartate transaminase (P<0.05). Moreover, complications including shock MESHD shock HP, coagulopathy, acidosis MESHD acidosis HP, sepsis MESHD sepsis HP, acute respiratory distress HP syndrome MESHD (ARDS), intensive care unit (ICU) admission, and intubation were significantly higher in patients with higher severities. O2 saturation, nausea MESHD nausea/vomiting HP/ vomiting MESHD, and extent of lung CT involvement were independent predictors of severe/critical COVID-19 (OR=0.342, 45.93, and 25.48, respectively; P<0.05).Conclusions: Our results indicate O2 saturation, nausea MESHD nausea/vomiting HP/ vomiting MESHD, and extent of lung CT involvement as independent predictors of severe COVID-19 conditions. Serum SERO CRP levels and pO2 were also considerably higher patients with higher severity and can be used along with other factors as possible predictors of severe disease MESHD in COVID-19 patients.

    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: 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 2019 coronavirus disease MESHD (COVID-19) has become an unprecedented public health crisis with nearly 16 million confirmed cases TRANS and 630,000 deaths MESHD worldwide. Methods: We retrospectively investigated the demographic, clinical, laboratory, radiological and treatment data of COVID-19 patients consecutively enrolled from January 18 to May 15, 2020, in Taihe and Jinzhou central hospital. Results: Of all 197 patients, the median age TRANS was 66.5 years (IQR 7-76), and 120 (60.9%) patients were males TRANS. We identified 88 (44.7%) of 197 COVID-19 patients as the disease progression MESHD (aggravation) cases. The aggravation cases tend to have more medical comorbidity: hypertension MESHD hypertension HP (34.1%), diabetes (30.7%), and presented with dyspnea MESHD dyspnea HP (34.1%), neutrophilia HP (60.2%), and lymphocytopenia (73.9%), compared with those without. And the patients with disease progression MESHD showed significantly higher level of Fibrinogen (Fbg), D-dimer, IL-6, C-reactive protein (CRP), procalcitonin (PCT), and serum SERO ferritin, and were more prone to develop organ damage in the liver, kidney, and heart (P<0.05). Multivariable regression showed that advanced age TRANS, comorbidities, lymphopenia MESHD lymphopenia HP, and elevated level of Fbg, lactate dehydrogenase (LDH), Cardiac troponin (CTnI), IL-6, serum SERO ferritin were the significant predictors of disease progression MESHD. Further, we investigated antibody SERO responses to SARS-CoV-2 and found that the levels of IgM and IgG were significantly higher in the disease progression MESHD cases compared to non-progression cases from 3 weeks after symptom onset TRANS. In addition, the disease progression MESHD group tended to peak later and has a more vigorous IgM/IgG response against SARS-CoV-2. Further, we performed Kaplan-Meier analysis and found that 61.6% of patients had not experienced ICU transfer or survival from hospital within 25 days from admission.Conclusions: Investigating the potential factors of advanced age TRANS, comorbidities and elevated level of IL-6, serum SERO ferritin and Kaplan-Meier analysis enables early identification and management of patients with poor prognosis. Detection of the dynamic antibody SERO may offer vital clinical information during the course of SARS-CoV-2 and provide prognostic value for patients infection MESHD.

    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.

    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.

    Objective The occurrence of pneumonia MESHD pneumonia HP separates severe cases of COVID-19 from the majority of cases with mild disease MESHD. However, the factors determining whether or not pneumonia MESHD pneumonia HP develops remain to be fully uncovered. We therefore explored the associations of several lifestyle factors with signs of pneumonia MESHD pneumonia HP in COVID-19. Methods Between May and July 2020, we conducted an online survey of 201 adults TRANS in Germany who had recently gone through COVID-19, predominantly as outpatients. Of these, 165 had a PCR-based diagnosis and 36 had a retrospective diagnosis by antibody testing SERO. The survey covered demographic information, eight lifestyle factors, comorbidities and medication use. We defined the main outcome as the presence vs. the absence of signs of pneumonia MESHD pneumonia HP, represented by dyspnea MESHD dyspnea HP, the requirement for oxygen therapy or intubation. Results Signs of pneumonia MESHD pneumonia HP occurred in 39 of the 165 individuals with a PCR-based diagnosis of COVID-19 (23.6%). Among the lifestyle factors examined, only overweight MESHD overweight HP/ obesity MESHD obesity HP associated with signs of pneumonia MESHD pneumonia HP (odds ratio 2.68 (1.29 - 5.59) p=0.008). The observed association remained significant after multivariate adjustment, with BMI as a metric variable, and also after including the antibody SERO-positive individuals into the analysis. Conclusions This exploratory study finds an association of overweight MESHD overweight HP/ obesity MESHD obesity HP with signs of pneumonia MESHD pneumonia HP in COVID-19. This finding suggests that a signal proportional to body fat mass, such as the hormone leptin, impairs the body's ability to clear SARS-CoV-2 before pneumonia MESHD pneumonia HP develops. This hypothesis concurs with previous work and should be investigated further to possibly reduce the proportion of severe cases of COVID-19.
