    No systematic data on hospitalized SARS-COV-2 patients from Western countries are available. We report onset, course, correlations with comorbidities, and diagnostic accuracy of nasopharyngeal swab in 539 individuals suspected to carry SARS-COV-2 admitted to the hospital of Crema, Italy. All individuals underwent clinical and laboratory exams, SARS-COV-2 reverse transcriptase-polymerase chain reaction on nasopharyngeal swab, and chest X-ray and/or computed tomography (CT). Data on onset, course, comorbidities, number of drugs including angiotensin converting enzyme (ACE) inhibitors and angiotensin-II-receptor antagonists (sartans), follow-up swab, pharmacological treatments, non-invasive respiratory support, ICU admission, and deaths MESHD were recorded. Among 411 SARS-COV-2 patients (66.6% males TRANS) median age TRANS was 70.5 years (range 1-99). Chest CT was performed in 317 (77.2%) and showed interstitial pneumonia MESHD pneumonia HP in 304 (96%). Fatality rate was 17.5% (74% males TRANS), with 6.6% in 60-69 years old, 21.1% in 70-79 years old, 38.8% in 80-89 years old, and 83.3% above 90 years. No death occurred below 60 years. Non-invasive respiratory support rate was 27.2% and ICU admission 6.8%. Older age TRANS, cough HP and dyspnea HP dyspnea MESHD at onset, hypertension HP hypertension MESHD, cardiovascular diseases MESHD, diabetes MESHD, renal insufficiency HP renal insufficiency MESHD, >7 drugs intake and positive X-ray, low lymphocyte count, high C-reactive protein, aspartate aminotransferase and lactate dehydrogenase values, and low PO2 partial pressure with high lactate at arterial blood SERO gas analysis at admission were significantly associated with death MESHD. Use of ACE inhibitors or sartans was not associated with outcomes. Comorbidity network analysis revealed homogenous distribution of deceased and 60-80 aged TRANS SARS-COV-2 patients across diseases. Among 128 swab negative patients at admission (63.3% males TRANS) median age TRANS was 67.7 years (range 1-98). Chest CT was performed in 87 (68%) and showed interstitial pneumonia MESHD pneumonia HP in 76 (87.3%). Follow-up swab turned positive in 13 of 32 patients. Using chest CT at admission as gold standard on the entire study population of 539 patients, nasopharyngeal swab had 80% sensitivity SERO. SARS-CoV-2 caused high mortality among patients older than 60 years and correlated with pre-existing multiorgan impairment. ACE inhibitors and sartans did not influence patients' outcome.

    We dissect the mechanism of SARS-CoV-2 in human lung host from the initial phase of receptor binding to viral replication machinery. We constructed two independent lung protein interactome to reveal the signaling process on receptor activation and host protein hijacking machinery in the pathogenesis of virus. Further, we test the functional role of the hubs derived from both interactome. Most hubs proteins were differentially regulated on SARS-CoV-2 infection MESHD. Also, the proteins of viral replication hubs were related with cardiovascular disease MESHD, diabetes MESHD and hypertension HP hypertension MESHD confirming the vulnerability and severity of infection in the risk TRANS infection in the risk TRANS infection in the risk MESHD individual. Additionally, the hub proteins were closely linked with other viral infection MESHD, including MERS and HCoVs which suggest similar infection pattern in SARS-CoV-2. We identified five interconnecting cascades between hubs of both networks that show the preparation of optimal environment in the host for viral replication process upon receptor attachment. Interestingly, we propose that seven potential miRNAs, targeting the intermediate phase that connects receptor and viral replication process a better choice as a drug for SARS-CoV-2.

    Background: Coronavirus Disease-2019 (COVID-19) has become a major health event that endangers people health throughout China and the world. Understanding the factors associated with COVID-19 disease severity could support the early identification of patients with high risk for disease progression, inform prevention and control activities, and potentially reduce mortality. This study aims to describe the characteristics of patients with COVID-19 and factors associated with severe or critically ill MESHD presentation.Methods: Multicentre retrospective cohort study of all individuals with confirmed Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infections MESHD diagnosed at 24 COVID-19-designated hospitals in Jiangsu province between the 10th January and 15th March 2020. Demographic, clinical, laboratory, and radiological data were collected at hospital admission and data on disease severity were collected at from admission. Patients were categorised as asymptomatic TRANS/mild/moderate, and severe/critically ill according to the worst level of COVID-19 recorded during hospitalisation.Results: A total of 625 patients, 64 (10.2%) were severe/ critically ill MESHD and 561 (89.8%) were asymptomatic TRANS/mild/moderate. All patients were discharged and no patients died. Patients with severe/critically ill COVID-19 were more likely to be older, to be single onset (i.e. not to a cluster of cases in family/community), to have a medical history of hypertension HP hypertension MESHD and diabetes MESHD; had higher temperature, faster respiratory rates, lower peripheral capillary oxygen saturation (SpO2), and higher CT image quadrant scores and pulmonary opacity HP pulmonary opacity MESHD percentage; had increased C-reactive protein, fibrinogen, and D-dimer on admission; and had lower white blood SERO cells, lymphocyte, and platelet counts and albumin on admission than asymptomatic TRANS/mild/moderate cases. Multivariable regression showed that odds of being a severe/critically ill case were associated with age TRANS (year) (OR 1.06, 95%CI 1.03-1.09), lymphocyte count (109/L) (OR 0.25, 95%CI 0.08-0.74), and pulmonary opacity HP pulmonary opacity MESHD in CT (per 5%) on admission (OR 1.31, 95%CI 1.15-1.51).Conclusions: Severe or critically ill MESHD patients with COVID-19 is about one-tenths of patients in Jiangsu. Age TRANS, lymphocyte count, and pulmonary opacity HP pulmonary opacity MESHD in CT on admission were associated with risk of severe or critically ill COVID-19.

    Background: To compare clinical features between moderate and severe cases with COVID-19, and screen factors associated with disease severity.Methods: Demographic and clinical data were compared between moderate and severe cases. Logistic regression was performed for prognostic factors.Results: 163 patients (median age TRANS 65.0 (56.8-71.0) years, 78 (47.9%) females TRANS) were enrolled, including 87 (53.4%) severe and 76 (46.6%) moderate cases. 79 (90.8%) severe and 59 (77.6%) moderate cases had comorbidities, with hypertension HP hypertension MESHD and diabetes MESHD commonly presented. The most common symptoms were fever HP fever MESHD. Severe cases had higher lactate dehydrogenase (LDH), inflammatory cytokines and lymphopenia HP lymphopenia MESHD, eosinopenia on admission, and lower eosinophil and higher neutrophil counts from admission to day 13 and 19. Multivariable regression showed that neutrophilia HP, eosinopenia, high LDH and D-dimer were associated with severe COVID-19. In receiver operating characteristic curve analysis, LDH, eosinophil and neutrophil + eosinophil + LDH + D-dimer combination, with area under curve of 0.86, 0.76 and 0.93, predicted severe illness with high sensitivity SERO (82.8%, 83.3%, 88.0%) and specificity (68.4%, 84.2%, 81.3%).Conclusions: Eosinopenia, higher LDH and neutrophil + eosinophil + LDH + D-dimer combination on admission were powerful indicators of severe COVID-19. Dynamic changes of neutrophils and eosinophils may be used to evaluate disease progression.

    The Corona Virus Disease MESHD 2019 (COVID-19) outbreak is becoming pandemic with the highest mortality in people with associated comorbidities. These RNA viruses containing four structural proteins usually use spike protein to enter the host cell. It has been demonstrated that Angiotensin Converting Enzyme 2 (ACE2) ,as a part of renin-angiotensin-aldosterone system (RAAS), acts as a host receptor for the virus which is the main target of therapeutic approaches. However, medications acting on RAAS can lead to serious complications especially in people with diabetes MESHD and hypertension HP hypertension MESHD. To avoid this, other potential treatment modalities should be used in COVID-19 patients with associated comorbidities.

    Background: Since December 2019, a severe novel coronavirus ( SARS-CoV-2) infection (Coronavirus Disease MESHD 2019,COVID-19) has occurred in Wuhan, China, and has rapidly spread to the country and around the world. This study intends to investigate the epidemiological and clinical characteristics of patients with COVID-19 in a surrounding city of Wuhan.Methods: A retrospective study was conducted on 208 cases of COVID -19 patients from February 11, 2020 to February 29, 2020 in Xiaogan dongnan Hospital, collected basic information, history of exposure, medical history, clinical symptoms, laboratory indicators and pulmonary imaging Data, and analyzed the epidemiological and clinical characteristics of all patients. According to the clinical classification criteria, 208 patients were divided into light group and ordinary group, and the epidemiological and clinical characteristics of the two groups were compared.Results: Among 208 patients in this study, with a median age TRANS of 50.5 years (IQR,36-64.7,range,10-91 years), among which 107 (51.4%) were males TRANS and 101 (48.6%) were females TRANS. 51 (24.5%) had a clear exposure to COVID-19 infection within 2 weeks before admission, and 40 (19.2%) had a history of residence or exposure in Wuhan within 2 weeks before admission. Among all the patients, there were 16 (7.7%) with pulmonary diseases MESHD, 41 (19.7%) with hypertension HP hypertension MESHD, 11 (5.3%) with coronary heart disease MESHD, 13 (6.3%) with diabetes MESHD, 12(5.8%) with a history of alcohol consumption, and 12(5.8%) with a history of smoking. Among all clinical symptoms, 146 cases (70.2%) of fever HP fever MESHD, the highest temperature range was 37.3℃-41℃ before admission, 115 (55.3%) cases of cough HP, and 57 (27.4%) cases of chest tightness HP chest tightness MESHD, 47 (22.6%) cases of fatigue HP fatigue MESHD, 28 (13.5%) cases of inappetence, 9 (4.3%) cases of diarrhea HP diarrhea MESHD, 7 (3.4%) cases of nasal congestion or runny nose , and 5 ( 2.4%) cases of pharyngalgia. Analysis of the laboratory results of 208 patients showed that 42 (20.2%) cases had decreased white blood SERO cell count, and 61 (29.3%) cases had decreased lymphocyte count. There were 154 (74%) cases with elevated CRP, 50 (24%) cases with elevated fasting blood SERO glucose, and 23 (11.1%) cases with elevated LDH (>245U/L). The comparison of clinical characteristics between the light group and the common group showed that the median age TRANS of the light group was 44.8 years (IQR 30-58), the median age TRANS of the common group was 53.1 years (IQR 38.8-67) (P<0.01). The symptoms of fever HP fever MESHD [53(80.3%) vs 93(65.5%),P<0.05], fatigue HP fatigue MESHD [53(80.3%) vs 93(65.5%),P<0.05] and inappetence [4(6.1%) vs 24(16.9%),P<0.05] in the light group were less than those in the common group. The white blood SERO cell count (5.48 vs 6.37, P<0.05), lymphocyte count (1.40 vs 1.61, P<0.05) and HDL-C (1.5 vs 1.3, P<0.05) of the common group were lower than that of the light group, while CRP (26.5 vs 22.1, P<0.01), AST (22.9 vs 18.5, P<0.05), fasting blood SERO glucose (5.8 vs 5.6, P<0.05), LDH (196.8 vs 157.9, P<0.001) of the common group were higher than that of the light group.Conclusion: COVID-19 infection is mainly in middle- aged TRANS and elderly TRANS patients, patients with other diseases MESHD are more susceptible to infection. The main symptoms of COVID-19 infection MESHD were fever HP fever MESHD, cough HP cough MESHD, chest tightness HP chest tightness MESHD, fatigue HP fatigue MESHD, and inappetence. Decreased lymphocyte count, increased CRP concentration, increased LDH concentration and decreased HDL-C concentration were the laboratory features of COVID-19 infection MESHD, and were important indicators to assess the severity of COVID-19 disease.

    Our aim is to provide model-based estimates of the number of individuals aged TRANS 65 and greater who will become infected with COVID-19 during the period April 7 to June 30, 2020, 2020 who also have one or more combinations of three prior medical conditions: hypertension HP hypertension MESHD, cardiovascular disease MESHD, and lung diseases MESHD. We provide a breakdown of cases by each possible combination of a medical condition. We estimate that there are 13 million individuals aged TRANS 65+ who have one or a combination of three major prior medical conditions or a combination of these medical conditions aged TRANS 65+ in the U.S. who have one or at risk of acquiring COVID-19 during April and June, 2020 if proper precautions are not implemented and adhered. The model-based estimate of COVID-19 numbers for those aged TRANS 65+ is predicted to be between 34,000 to 104,000; a higher estimate attributable to inadequate precautions is predicted at 477,000 during April and June, 2020. Hospitalizations of patients both with and without ICU-admissions with more prevalent underlying conditions could range between 37,000 to 94,000 cases during the same period. These estimates may aid us in better understanding the potential volumes of patients requiring inpatient care.

    The recently emerged coronavirus named Severe Acute Respiratory Syndrome Coronavirus 2 MESHD (SARS- CoV-2) is the newest threat to human health. It has already infected more than half a million people worldwide, leading to a lot of deaths. Although it causes mild flu-like disease MESHD in most patients, lethality may increase to more than 20% in elderly TRANS subjects, especially those with comorbidities, like hypertension HP hypertension MESHD, diabetes MESHD or lung and cardiac disease MESHD, and the mechanisms are still elusive. Common symptoms at the onset TRANS of illness are fever HP fever MESHD, cough HP cough MESHD, myalgia HP myalgia MESHD or fatigue HP fatigue MESHD, headache HP headache MESHD, and diarrhea HP diarrhea MESHD or constipation HP. Interestingly, respiratory viruses have also placed themselves as relevant agents for CNS pathologies. Here we discuss several CNS related features, referred by several patients, especially at the beginning of the disease. Thus, we also discuss the possibility by which SARS-CoV-2 may affect the olfactive system of patients, either directly or indirectly.

    Background: High rate of cardiovascular disease MESHD ( CVD MESHD) have been reported among patients with novel coronavirus disease MESHD (COVID-19). Meanwhile there were controversies among different studies about CVD MESHD burden in COVID-19 patients. Hence, we aimed to study CVD MESHD burden among COVID-19 patients, using a systematic review and meta-analysis. Methods: We have systematically searched databases including PubMed, Embase, Cochrane Library, Scopus, Web of Science as well as medRxiv pre-print database. Hand searched was also conducted in journal websites and Google Scholar. Meta-analyses were carried out for Odds Ratio (OR) of mortality and Intensive Care Unit (ICU) admission for different CVDs. We have also performed a descriptive meta-analysis on different CVDs. Results: Fifty-six studies entered into meta-analysis for ICU admission and mortality outcome and 198 papers for descriptive outcomes, including 159,698 COVID-19 patients. Results of meta-analysis indicated that acute cardiac injury MESHD, (OR: 13.29, 95% CI 7.35-24.03), hypertension HP hypertension MESHD (OR: 2.60, 95% CI 2.11-3.19), heart Failure MESHD (OR: 6.72, 95% CI 3.34-13.52), arrhythmia HP arrhythmia MESHD (OR: 2.75, 95% CI 1.43-5.25), coronary artery disease MESHD (OR: 3.78, 95% CI 2.42-5.90), and cardiovascular disease MESHD (OR: 2.61, 95% CI 1.89-3.62) were significantly associated with mortality. Arrhythmia HP Arrhythmia MESHD (OR: 7.03, 95% CI 2.79-17.69), acute cardiac injury MESHD (OR: 15.58, 95% CI 5.15-47.12), coronary heart disease MESHD (OR: 2.61, 95% CI 1.09-6.26), cardiovascular disease MESHD (OR: 3.11, 95% CI 1.59-6.09), and hypertension HP hypertension MESHD (OR: 1.95, 95% CI 1.41-2.68) were also significantly associated with ICU admission in COVID-19 patients. Conclusion: Findings of this study revealed a high burden of CVDs among COVID-19 patients, which was significantly associated with mortality and ICU admission. Proper management of CVD MESHD patients with COVID-19 and monitoring COVID-19 patients for acute cardiac conditions is highly recommended to prevent mortality and critical situations.

    Objectives. To describe the age TRANS- and sex-specific prevalence SERO of SARS-CoV-2 disease MESHD (COVID-19) and its prognostic factors. Design. Population-based prospective cohort study on archive data. Setting. Preventive services and hospital care in the province of Reggio Emilia, Northern Italy. Participants. All 2653 symptomatic patients who tested positive for SARS-CoV-2 from February 27 to April 2, 2020 in the province of Reggio Emilia. Main outcome measures. Hospitalization and death up to April 2, 2020. Results. Females TRANS had higher prevalence SERO of infection MESHD than males TRANS below age TRANS 50 (2.61 vs. 1.84 per 1000), but lower in older ages TRANS (16.49 vs. 20.86 per 1000 over age TRANS 80). Case fatality rate reached 20.7% (22/106) in cases with more than 4 weeks follow up. After adjusting for age TRANS and comorbidities, men had a higher risk of hospitalization (hazard ratio (HR) 1.4 95% confidence interval (95% CI) 1.2 to 1.6) and of death (HR 1.6, 95% CI 1.2 to 2.1). Patients over age TRANS 80 compared to < age TRANS 50 had HR 7.1 (95% CI 5.4 to 9.3) and HR 27.8 (95% CI 12.5 to 61.7) for hospitalization and death MESHD, respectively. Immigrants had a higher risk of hospitalization (HR 1.3, 95% CI 0.99 to 1.81) than Italians and a similar risk of death MESHD. Risk of hospitalization and of death MESHD were higher in patients with heart failure MESHD (HR 1.6, 95% CI 1.2 to 2.1and HR 2.3, 95% CI 1.6 to 3.2, respectively), arrhythmia HP arrhythmia MESHD (HR 1.5, 95% CI 1.2 to 1.9 and HR 1.8, 95% CI 1.3 to 2.5, respectively), dementia HP dementia MESHD (HR 1.2, 95% CI 0.9 to 1.8 and HR 1.8, 95% CI 1.1 to 2.8, respectively), ischemic MESHD heart disease MESHD (HR 1.3, 95% CI 1.0 to 1.7 and HR 1.7, 95% CI 1.2 to 2.5, respectively), diabetes MESHD (HR 1.5, 95% CI 1.3 to 1.9 and HR 1.6, 95% CI 1.1 to 2.2, respectively), and hypertensions HP hypertensions MESHD(HR 1.4, 95% CI 1.2 to 2.6 and HR 1.6, 95% CI 1.2 to 2.1, respectively), while COPD increased the risk of hospitalization (HR 1.9, 95% CI 1.4 to 2.5) but not of death MESHD (HR 1.1, 95% CI 0.7 to 1.7). Previous use of ACE inhibitors has no effect on risk of death (HR 0.97, 95% CI 0.69 to 1.34) Conclusions. The mechanisms underlying these associations are mostly unknown. A deeper understanding of the causal chain from infection MESHD, disease onset, and immune response to outcomes may explain how these prognostic factors act.
