    Background: Coronavirus disease-2019 (COVID-19) has a broad clinical presentation, involving multiple organs besides the respiratory system. Currently, there is little evidence available on the presence of severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) in peritoneal fluid (PF). In this study, we describe the detection of SARS-CoV-2 in the PF of two patients with COVID 19 and kidney disease MESHD.Case presentation: Case 1: A 71-year-old woman with a history of end-stage kidney disease MESHD who presented with a 15-day evolution of progressive dyspnea HP dyspnea MESHD, accompanied by dry cough MESHD cough HP and fever HP fever MESHD; IgM antibodies SERO to SARS-CoV-2 were detected on admission. Real-time SARS-CoV-2 polymerase chain reaction (qRT-PCR) in the PF was positive. Three days after admission the patient's respiratory distress HP improved and she was discharged after 8 days of hospitalization.Case 2: A 78-year-old woman, with type 2 diabetes MESHD, hypertension HP hypertension MESHD, a 15-day history of polypnea, and a 5-day onset of fever HP fever MESHD and dyspnea HP dyspnea MESHD. IgM and IgG antibodies SERO to SARS-CoV-2 were detected on admission, as well as a positive nasopharyngeal qRT-PCR test for SARS-CoV-2. During hospitalization she developed acute kidney injury HP acute kidney injury MESHD, requiring peritoneal dialysis, SARS-CoV-2 was confirmed in PF by qRT-PCRConclusions: These two cases highlights the importance of increasing the level of awareness for the presence and possible SARS-CoV-2 transmission TRANS through non-respiratory routes, like peritoneal fluid.Emphasis should be given to appropriate preventive strategies for minimizing the risk of transmission TRANS of COVID-19 from patients on peritoneal dialysis in both inpatient and outpatient settings.

    Background: The coronavirus disease MESHD 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2), has been identified as the most crucial threat of the century. Due to severe pneumonia HP pneumonia MESHD and acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD), the SARS-CoV-2 can cause shortness of breath MESHD, hypoxemia HP hypoxemia MESHD, and the need to mechanical ventilation, intensive care unit (ICU) management, and eventual death MESHD. We have tried to use a non-invasive approach to prevent patient from needing respiratory support with invasive ventilation (IV). Here, for the first time, improvement of oxygen delivery and oxygen saturation levels were observed in a COVID-19 patient using packed red blood SERO cells (PRBCs) transfusion.Case presentation: A 63-year-old man with a history of smoking and addiction who came to our hospital facility with fever HP fever MESHD, shortness of breath MESHD and decreased blood SERO oxygen saturation. High-resolution chest CT revealed bilateral and multifocal ground-glass opacities consistent with COVID-19. Subsequently, the COVID-19 infection was confirmed TRANS infection was confirmed MESHD by real-time polymerase chain reaction (qRT-PCR) assay of the upper respiratory tract. Conclusions: Oxygen delivery and oxygen saturation improvement were observed in the COVID-19 patient, after PRBCs transfusions.

    Background Due to the latent onset of novel coronavirus disease MESHD 2019 (COVID-19), it is important to identify patients with increased probabilities for disease progression early in order to implement timely medical strategies. This study aimed to identify the factors associated with severe COVID-19 and evaluate the current antiviral drugs, especially in severe patients.Methods This was a retrospective observational study performed at the No. 7 Hospital of Wuhan (Wuhan, China) with hospitalized patients confirmed with COVID-19 from January 11 to March 13, 2020. Multivariable logistic regression analysis was used to identify the associated factors of severe COVID. Treatment of antivirus drugs were collected and evaluated.Results Of the 550 patients, 292 (53.1%) were female TRANS and 277 (50.4%) were ≥ 60 years old. The most common symptom was fever HP fever MESHD (n = 372, 67.7%), followed by dry cough MESHD cough HP (n = 257, 46.7%), and dyspnea HP dyspnea MESHD (n = 237, 43.1%), and fatigue HP fatigue MESHD (n = 224, 40.7%). Among the severe patients, 20.2% required invasive ventilator support and 18.0% required non-invasive ventilator. The identified risk factors for severe cases were: age ≥ 60 years (odds ratio (OR) = 3.02, 95% confidence interval (CI): 1.13–8.08, P = 0.028), D-dimer > 0.243 µg/ml (OR = 2.734, 95%CI: 1.012–7.387, P = 0.047), and low oxygenation index (OR = 0.984, 95%CI: 0.980–0.989, P < 0.001). In severe cases, the benefits of arbidol alone was 73.3%, which was better than ribavirin (7/17, 41.2%, P = 0.029).Conclusions Age ≥ 60 years, D-dimer > 0.243 µg/ml, and lower oxygenation index were associated with severe cases. Arbidol might provide more clinical benefits in treating patients with severe COVID-19 compared with other antiviral drugs.

    Background: In late December 2019, Covid-19 emerged as clusters of pneumonia HP pneumonia MESHD of unknown cause in a province of china, Wuhan. Etiological agent was identified as novel coronavirus that resembles severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East Respiratory syndrome coronavirus (MERS-CoV) MESHD and has zoonotic transmission TRANS. Covid pneumonia HP can remain asymptomatic TRANS, present as mild infection, severe HP infection, severe MESHD pneumonia HP pneumonia MESHD or respiratory failure HP respiratory failure MESHD. Diagnosis is based on rRT-PCR carried out on respiratory secretions. Covid related mortality exceeds 50% once patient requires ICU admission. Objective: To study the characteristics of ICU population admitted to ICU of Shifa International hospital.Results: we prospectively analysed 74 patients which included 43.3% females TRANS and 56.7% males TRANS. Commonest symptoms were shortness of breath MESHD (94.5%), fever HP fever MESHD (74.3%) and cough HP (74.3%). Most of our study population consisted of non-smokers (79.7%) and had hypertension HP hypertension MESHD (59.4%) followed by diabetes MESHD (47.2%). Hydroxychloroquine (HCQ) and azithromycin combination is superior to hydroxychloroquine and doxycycline in reducing mortality (p=0.023) whereas Doxycycline alone resulted in increased mortality (p=0.009). Those who did not require antibiotics or required only narrow spectrum antibiotics had increased survival and reduced requirement of invasive mechanical ventilation (p=< 0.0001). in our study population, (44.9%) developed acute kidney injury HP acute kidney injury MESHD, 2.7% needed re-intubations 10.8% developed surgical emphysema HP emphysema MESHD and 2.7 % thromboembolic MESHD events despite full anticoagulation. ICU mortality was 41.8% and was higher in females TRANS (59.4%, p=0.008), those who had SOFA score > 3.5 at time of admission, raised D-Dimers > 931 ng/ml, NLR > 9.2. It was further high in those who required invasive mechanical ventilation and vasopressor support (58.1% mortality p=< 0.001). ICU stay was more prolonged in those requiring invasive mechanical ventilation as compared to those who did not. (23 days vs 6 days, p=0.001). Mean plateau pressure was 19.6 ± 7.6; mean Driving pressures 14.4 ± 4.6; mean PaO2/FiO2 150.7 ± 73.9; mean SPO2/FiO2 173.9 ± 106.9; mean PEEP was 8.2 ±4.33.Conclusion: We concluded that severe covid pneumonia HP pneumonia MESHD is common amongst males TRANS, non-smokers those who had comorbid. HCQ and azithromycin combination is superior to combination of HCQ and doxycycline or doxycycline alone and QT prolongation MESHD is a rare complication. Baseline NLR, APACHI II, SOFA, SAPS II, NUTRIC scores, D-Dimers, invasive ventilation and vasopressor support are important tools to predict ICU mortality. Invasive mechanical ventilation carries higher mortality and associated with more prolonged ICU stay. AKI is most common complication followed by shock HP and surgical emphysema HP emphysema MESHD. CRP, Ferritin levels has no impact on outcome.

    Background: Coronavirus disease 2019 (COVID-19), a newly emerged respiratory disease MESHD caused by severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2), has recently become pandemic. Clinical observation indicated that elderly TRANS patients had high incidence of severe pneumonia HP pneumonia MESHD and poor treatment efficacy. Therefore, this study was to clarify the characteristics of elderly TRANS patients aged TRANS 75 or older with COVID-19 pneumonia HP pneumonia MESHD in order to guide rational treatment for elderly TRANS patients. Methods: we enrolled 331 elderly TRANS patients aged TRANS 75 or older with confirmed COVID-19 in Huoshenshan hospital of Wuhan from February 3rd to March 31st. The cases were divided into general, serious and critical groups according to severity after hospitalization, and the difference among groups were compared by R package statistics software. Results: Compared with general group, serious and critical groups had more underlying comorbidities and higher incidence of cough HP cough MESHD, breath shortness MESHD and anorexia HP anorexia MESHD. Moreover, there existed obviously differences in many of laboratory indexes and CT images among them. serious and critical elderly TRANS patients were more likely to receive oxygen, mechanical ventilation, expectorant, corticosteroid, abidor, cephaloprin, imipenem, human serum SERO albumin (HSA), nutrition support, anti SARS-CoV-2 positive plasma SERO and actemra. Multivariate analysis of factors showed that male TRANS sex, hypertension HP hypertension MESHD, diabetes MESHD, renal diseases MESHD, breath shortness MESHD, neutrophil, platelet, creatinine, lactate dehydrogenase were the risk factor for serious and critical illness. While blood SERO cell (WBC) was the protective factor. Conclusion: elderly TRANS patients have high incidence of severe pneumonia HP pneumonia MESHD and poor treatment efficacy. The reasons might be that many of the elderly TRANS patients with COVID-19 pneumonia HP pneumonia MESHD have certain chronic disease MESHD, poor immune function and a meager response to the virus. the pathogenic mechanism of SARS-CoV-2 might be involved in the cell-mediated immunity and cytokine storms by acting on lymphocytes.

    Purpose: To investigate the clinical characteristics, morbidities, management, and outcomes of COVID-19 Infected patients admitted to the intensive care unit (ICU) in Somalia.Material MESHD and methods: We conducted a retrospective observational study of laboratory 60 confirmed patients with severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) admitted to an ICU from March 28, to May 28, 2020.The sociodemographic characteristics, comorbidities, exposure history, clinical manifestations (symptoms and signs), laboratory findings, treatment, and outcomes were collected from medical records.Results: Most of the patients admitted to ICU were men over 59 years of age TRANS, and nearly half had diabetes MESHD followed by hypertension HP hypertension MESHD chronic kidney disease HP and asthma HP asthma MESHD. The most clinical presentations were dyspnea HP dyspnea MESHD (91.2%), Fever HP Fever MESHD (81.1%), (68.75%), Fatigue HP and myalgia HP myalgia MESHD (25%), and Altered level of conscious (16.6%). Among 48 patients admitted to the ICU, about 24 (50%) patients had required endotracheal intubation and mechanical ventilation, and 11(29.9%) patients needed noninvasive ventilation, while 13(27.08%) patients treated with high-flow oxygen therapy >15 L/min (Table 3). Corticosteroids were administered to most patients (85.4%), while 77.1% of the patients received inhaled bronchodilators and morethan half of the patients administered antibiotics. 58.3% of the patients had received Oseltamivir, while 22.9% received Vasopressors.Conclusion This study represents the first description of critically ill MESHD patients infected with SARS-CoV-2 admitted to ICU in Somalia. The study identified that elder age TRANS, male TRANS gender TRANS, and diabetic MESHD and hypertensive MESHD comorbidities as independent risk factors of poor outcomes for patients admitted to the ICU (p<0.005).

    Background: SARS-CoV-2 is the etiological agent of coronavirus disease MESHD 2019 (COVID-19), which has a wide range of disease manifestations, including relatively mild respiratory illness MESHD to severe disease requiring hospitalization. Patients with signs of COVID-19 ( fever HP fever MESHD, coughing HP, shortness of breath MESHD) were tested for the virus by targeting specific SARS-COV-2 genomic loci via RT-PCR using RNA extracted from nasopharyngeal/nasal swabs specimens. However, this testing does not yield genetic information required for identifying viral evolution or variants. Therefore, we sequenced 200 specimens from positively identified cases in Nevada through our robust protocol for sequencing SARS-CoV-2 genomes directly from patient's nasopharyngeal/nasal swabs. This protocol enabled identification of specific nucleotide variants including those for D614G and clade defining mutations. Additionally, these sequences were used to determine the phylogenetic relationships of SARS-CoV-2 genomes of public health importance occurring in the state of Nevada. Results: Our study reports a novel finding of a variant in the nsp12 (RdRp) protein at residue 323 (314aa of orf1b) to Phenylalanine (F) from Proline (P), present in the original isolate of SARS-CoV-2 (Wuhan-1). This 323F variant is found at a very high frequency in Northern Nevada compared to other geographic areas. Structural modeling of the RdRP interface domain indicates the P323F variant did not significantly change the protein conformation. Conclusions: Our results highlight the introduction and spread of specific SARS-CoV-2 variants at a very high frequency within a distinct geographic location. This is important for clinical and public health perspectives in understanding the transmission TRANS and evolution of SARS-CoV-2 as it circulates in humans.

    The coronavirus disease MESHD 2019 (COVID-19) pandemic, caused by Severe Acute Respiratory Syndrome MESHD (SARS)-CoV-2, continues to burden medical institutions around the world by increasing total hospitalization and Intensive Care Unit (ICU) admissions. A better understanding of symptoms, comorbidities and medication used for pre-existing conditions in patients with COVID-19 could help healthcare workers identify patients at increased risk of developing more severe disease. Here, we have used self-reported data (symptoms, medications and comorbidities) from more than 3 million users from the COVID-19 Symptom Tracker app12 to identify previously reported and novel features predictive of patients being admitted in a hospital setting. Despite previously reported association between age TRANS and more severe disease phenotypes, we found that patient's age TRANS, sex and ethnic group were minimally predictive when compared to patient's symptoms and comorbidities. The most important variables selected by our predictive algorithm were fever HP fever MESHD, the use of immunosuppressant medication, mobility aid, shortness of breath MESHD and fatigue HP fatigue MESHD. It is anticipated that early administration of preventative measures in COVID-19 positive patients (COVID+) who exhibit a high risk of hospitalization signature may prevent severe disease progression.

    Background: Understanding the factors associated with disease severity and mortality in Coronavirus disease MESHD (COVID19) is imperative to effectively triage patients. We performed a systematic review to determine the demographic, clinical, laboratory and radiological factors associated with severity and mortality in COVID-19. Methods: We searched PubMed, Embase and WHO database for English language articles from inception until May 8, 2020. We included Observational studies with direct comparison of clinical characteristics between a) patients who died and those who survived or b) patients with severe disease and those without severe disease. Data extraction and quality assessment were performed by two authors independently. Results: Among 15680 articles from the literature search, 109 articles were included in the analysis. The risk of mortality was higher in patients with increasing age TRANS, male TRANS gender TRANS (RR 1.45; 95%CI 1.23,1.71), dyspnea HP dyspnea MESHD (RR 2.55; 95%CI 1.88,2.46), diabetes MESHD (RR 1.59; 95%CI 1.41,1.78), hypertension HP hypertension MESHD (RR 1.90; 95%CI 1.69,2.15). Congestive heart failure HP Congestive heart failure MESHD (OR 4.76; 95%CI 1.34,16.97), hilar lymphadenopathy HP lymphadenopathy MESHD (OR 8.34; 95%CI 2.57,27.08), bilateral lung involvement (OR 4.86; 95%CI 3.19,7.39) and reticular pattern (OR 5.54; 95%CI 1.24,24.67) were associated with severe disease. Clinically relevant cut-offs for leukocytosis HP leukocytosis MESHD(>10.0 x109/L), lymphopenia HP lymphopenia MESHD(< 1.1 x109/L), elevated C-reactive protein(>100mg/L), LDH(>250U/L) and D-dimer(>1mg/L) had higher odds of severe disease and greater risk of mortality. Conclusion: Knowledge of the factors associated of disease severity and mortality identified in our study may assist in clinical decision-making and critical-care resource allocation for patients with COVID-19.

    Background: This study aimed to assess the knowledge and attitude of dental professionals in Saudi Arabia regarding severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) and coronavirus disease MESHD 2019 (COVID-19).Methods: A questionnaire was developed to assess various dental professionals from both governmental and private sectors through online and social media outlets. Results: A total of 1,033 responses were collected. Moreover, 63.4% of respondents (63.4%) were working in hospitals. Of all respondents, 44.9%, 33.4%, and 21.7% were in governmental clinics, academia, and private sector, respectively. Overall knowledge on incubation period TRANS and route of transmission TRANS of SARS-CoV-2 was satisfactory across all dental professions. All dental professionals except for dental assistants demonstrated adequate knowledge on the recommended hand-soap cleaning time (p < 0.001). Most dental professionals displayed unsatisfactory knowledge and disagreement on the survival of SARS-CoV-2 outside the host (p < 0.001). Furthermore, 75.1% of respondents were reluctant to treat a suspected COVID-19 patient, and 92% participants believed that the mode of transmission TRANS was droplet inhalation. Fever HP Fever MESHD, coughing HP, and shortness of breath MESHD were identified as the most common symptoms of COVID-19. Most standard methods of prevention in the dental office were selected by at least 50% of participants. Conclusions: An appropriate level of knowledge on SARS-CoV-2 incubation period TRANS and signs and symptoms of COVID-19 was noted among all dental professionals in Saudi Arabia. Perceived survival outside the host was modest. A certain level of apprehension toward suspected SARS-CoV-2 patients existed among most professionals. Pandemic-awareness campaigns are essential among healthcare providers.
