    With the continuing coronavirus disease MESHD 2019 (COVID-19) pandemic coupled with phased reopening, it is critical to identify risk factors associated with susceptibility and severity of disease MESHD in a diverse population to help shape government policies, guide clinical decision making, and prioritize future COVID-19 research. In this retrospective case-control study, we used de-identified electronic health records (EHR) from the University of California Los Angeles (UCLA) Health System between March 9th, 2020 and June 14th, 2020 to identify risk factors for COVID-19 susceptibility (severe acute respiratory distress HP syndrome MESHD coronavirus 2 (SARS-CoV-2) PCR test positive), inpatient admission, and severe outcomes (treatment in an intensive care unit or intubation). Of the 26,602 individuals tested by PCR for SARS-CoV-2, 992 were COVID-19 positive (3.7% of Tested), 220 were admitted in the hospital (22% of COVID-19 positive), and 77 had a severe outcome (35% of Inpatient). Consistent with previous studies, males TRANS and individuals older than 65 years old had increased risk of inpatient admission. Notably, individuals self-identifying as Hispanic or Latino constituted an increasing percentage of COVID-19 patients as disease MESHD severity escalated, comprising 24% of those testing positive, but 40% of those with a severe outcome, a disparity that remained after correcting for medical co-morbidities. Cardiovascular disease MESHD, hypertension, and renal MESHD hypertension HP disease MESHD were premorbid risk factors present before SARS-CoV-2 PCR testing associated with COVID-19 susceptibility. Less well-established risk factors for COVID-19 susceptibility included pre-existing dementia MESHD dementia HP (odds ratio (OR) 5.2 [3.2-8.3], p=2.6 x 10-10), mental health conditions (depression OR 2.1 [1.6-2.8], p=1.1 x 10-6) and vitamin D deficiency MESHD (OR 1.8 [1.4-2.2], p=5.7 x 10-6). Renal diseases MESHD including end-stage renal disease MESHD and anemia MESHD anemia HP due to chronic renal disease MESHD were the predominant premorbid risk factors for COVID-19 inpatient admission. Other less established risk factors for COVID-19 inpatient admission included previous renal transplant (OR 9.7 [2.8-39], p=3.2x10-4) and disorders of the immune system (OR 6.0 [2.3, 16], p=2.7x10-4). Prior use of oral steroid medications was associated with decreased COVID-19 positive testing risk (OR 0.61 [0.45, 0.81], p=4.3x10-4), but increased inpatient admission risk (OR 4.5 [2.3, 8.9], p=1.8x10-5). We did not observe that prior use of angiotensin converting enzyme inhibitors or angiotensin receptor blockers increased the risk of testing positive for SARS-CoV-2, being admitted to the hospital, or having a severe outcome. This study involving direct EHR extraction identified known and less well-established demographics, and prior diagnoses and medications as risk factors for COVID-19 susceptibility and inpatient admission. Knowledge of these risk factors including marked ethnic disparities observed in disease MESHD severity should guide government policies, identify at-risk populations, inform clinical decision making, and prioritize future COVID-19 research.

    Introduction: Coronavirus disease MESHD-2019 (COVID-19), caused by severe acute respiratory syndrome MESHD coronavirus-2 (SARS-CoV-2), is causing dramatic morbidity and mortality worldwide. The Red Blood SERO Cell Distribution Width (RDW) has been strongly associated with increased morbidity and mortality in multiple diseases MESHD. Objective: To assess if elevated RDW is associated with unfavorable outcomes in hospitalized COVID-19. Methods: We retrospectively studied clinical outcomes of hospitalized COVID-19 patients for their RDW values. In-hospital mortality was defined as primary outcome, while septic shock MESHD shock HP, need for mechanical ventilation, and length of stay (LOS) were secondary outcomes. Results- A total of 294 COVID-19 patients were finally studied. Overall prevalence SERO of increased RDW was 49.7% (146/294). RDW was associated with increased risk of in-hospital mortality (aOR, 4.5; 95%CI, 1.4-14.3) and septic shock MESHD shock HP (aOR, 4.6; 95%CI, 1.4-15.1) after adjusting for anemia MESHD anemia HP, ferritin, and lactate. The association remained unchanged even after adjusting for other clinical confounders such as age TRANS, sex, body mass index, coronary artery disease MESHD, hypertension MESHD hypertension HP, diabetes mellitus MESHD diabetes mellitus HP, and chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP. No association was found instead with mechanical ventilation and median LOS. Conclusion: Elevated RDW in hospitalized COVID-19 patients is associated with a significantly increased risk of mortality and septic shock MESHD shock HP.

    Background: Ribavirin (RBV) is been used for SARS-CoV-2 infection MESHD. This drug is associated with a wide range of side effects, mainly anemia MESHD anemia HP, so its use in patients with potential respiratory affectation could not be appropriate. The evidences of adverse events associated with RBV-use has mainly been derived in the context of hepatitis C MESHD hepatitis HP (HCV) treatment, however the possible use of RBV in CoVID-19 patients could be limited to 14 days. Methods: Longitudinal study including HIV/HCV coinfected patients. We evaluate the hemoglobin dynamics and reductions as well as evaluate the development rate of anemia MESHD anemia HP during the first 2 weeks of therapy in HCV infected patients. Results: 189 patients were included in the study. The median hemoglobin levels were 14.6 g/dL (IQR: 13.2-15.6 g/dL) and 13.5 g/dL (IQR: 12.3-14.5 g/dL) at weeks 1 and 2 of therapy, respectively. A cumulative number of 27 (14.2%) patients developed anemia MESHD anemia HP (23 grade 1 [12.1%] and 4 grade 2 [2.1%]). We identify a baseline hemoglobin levels of 14 g/dL as the better cut-off to identify those patients with a high chance to develop anemia MESHD anemia HP. Of the 132 patients with baseline hemoglobin level >14 g/dL, 8 developed anemia MESHD anemia HP (6.1%) compared with 19 of 57 (33.3%) with hemoglobin levels lower than 14 g/dL (p < 0.001). Conclusions: Our study shows valuable information about the early hemoglobin kinetic timing in patients on RBV-therapy, that could be useful to tailor CoVID-19 treatment if RBV use is considered.

    Background: The coronavirus disease MESHD (COVID-19) first identified in Wuhan in December 2019 became a pandemic within a few months of its discovery. The impact of COVID-19 is due to both its rapid spread and its severity, but the determinants of severity have not been fully delineated. Objective: Identify factors associated with hospitalization and disease MESHD severity in a racially and ethnically diverse cohort of COVID-19 patients. Methods: We analyzed data from COVID-19 patients diagnosed at the University of Cincinnati health system from March 13, 2020 to May 31, 2020. Severe COVID-19 was defined as admission to intensive care unit or death MESHD. Logistic regression modeling adjusted for covariates was used to identify the factors associated with hospitalization and severe COVID-19. Results: Among the 689 COVID-19 patients included in our study, 29.2% were non-Hispanic White, 25.5% were non-Hispanic Black, 32.5% were Hispanic, and 12.8% were of other race/ethnicity. About 31.3% of patients were hospitalized and 13.2% had severe disease MESHD. In adjusted analyses, the sociodemographic factors associated with hospitalization and/or disease MESHD severity included older age TRANS, non-Hispanic Black or Hispanic race/ethnicity (compared to non-Hispanic White), and smoking. The following comorbidities: diabetes, hypercholesterolemia MESHD hypercholesterolemia HP, asthma MESHD asthma HP, COPD, chronic kidney disease HP kidney disease MESHD, cardiovascular diseases MESHD, osteoarthritis MESHD osteoarthritis HP, and vitamin D deficiency MESHD were associated with hospitalization and/or disease MESHD severity. Hematological disorders such as anemia MESHD anemia HP, coagulation disorders, and thrombocytopenia MESHD thrombocytopenia HP were associated with both hospitalization and disease MESHD severity. Conclusion: This study confirms race and ethnicity as predictors of severe COVID-19. It also finds clinical risk factors for hospitalization and severe COVID-19 not previously identified such a vitamin D deficiency MESHD, hypercholesterolemia MESHD hypercholesterolemia HP, osteoarthritis MESHD osteoarthritis HP, and anemia MESHD anemia HP.

    Iron metabolism and anemia MESHD anemia HP may play an important role in multiple organ dysfunction syndrome MESHD in Coronavirus disease MESHD 2019 (COVID-19). If confirmed, this has important implications for the more than 1.62 billion people estimated to have anemia MESHD anemia HP globally. We conducted a systematic review and meta-analysis to evaluate biomarkers of anemia MESHD anemia HP and iron metabolism (hemoglobin, ferritin, transferrin, soluble transferrin receptor, hepcidin, haptoglobin, unsaturated iron-binding capacity, erythropoietin, free erythrocyte protoporphyrine, and prevalence SERO of anemia MESHD anemia HP) in patients diagnosed with COVID-19, and explore their prognostic value. Six bibliographic databases were searched up to May 5th 2020. We included 56 unique studies, with data from 14,044 COVID-19 patients (59 years median age TRANS). Pooled mean hemoglobin and ferritin levels in COVID-19 patients across all ages TRANS were 130.41 g/L (95% Confidence Interval (CI), 128.42; 132.39) and 673.91 ng/mL (95% CI, 420.98; 926.84), respectively. Hemoglobin levels decreased with advancing age TRANS and increasing percentage of comorbid and critically ill patients, while levels of ferritin increased with increasing male TRANS proportion and mean hemoglobin levels. Compared to moderate cases, severe cases had lower pooled mean hemoglobin [weighted mean difference (WMD), -4.21 (95% CI -6.63; -1.78)] and higher ferritin [WMD, -730.55 ng/mL (95% CI 413.24; 1047.85)]. A significant difference in mean ferritin level of 1027.23 ng/mL (95% CI 819.53; 1234.94) was found between survivors and non-survivors, but not in hemoglobin levels. No studies provided information on anemia MESHD anemia HP or other biomarkers of interest. Future studies should explore the impact of iron metabolism and anemia MESHD anemia HP and in the pathophysiology, prognosis, and treatment of COVID-19.

    Introduction Coronavirus Disease MESHD (COVID-19) is caused by SARS-CoV-2 infection MESHD. Indonesia officially established the first COVID-19 confirmation case in early March 2020. East Kalimantan has been determined as a candidate for the new capital of Indonesia since 2019. This makes Abdul Wahab Sjahranie Hospital Samarinda as the largest hospital there has been designated as the main referral hospital for COVID-19 patients in East Kalimantan. We report the epidemiological, clinical, laboratory, and radiological characteristics of these patients. Methods All patients with laboratory-confirmed COVID-19 by RT-PCR were admitted to Abdul Wahab Sjahranie Hospital in Samarinda. We retrospectively collected and analyzed data on patients with standardized data collection from medical records. Results By May 8, 2020, 18 admitted hospital patients had been identified as having laboratory-confirmed COVID-19. Most of the infected patients were men (16 [88.9%] patients); less than half had underlying diseases MESHD (7 [38.9%] patients). Common symptoms at the onset TRANS of illness were cough MESHD cough HP (16 [88.9%] patients), sore throat (8 [44.4%] patients), and fever MESHD fever HP (8 [44.4%] patients). Laboratory findings of some patients on admission showed anemia MESHD anemia HP. Levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were increased in 10 (55.6%) of 18 patients. On admission, abnormalities in chest x-ray images were detected in 6 (33.3%) patients who had pneumonia MESHD pneumonia HP. The mean duration from the first hospital admission to discharge was 33.1 days. Discussion The majority of COVID-19 patients are male TRANS. COVID-19 comorbidities were found in several patients. The main clinical symptoms of COVID-19 in this study were cough MESHD cough HP, sore throat, and fever MESHD fever HP. The abnormal laboratory finding in COVID-19 patients is anemia MESHD anemia HP, an increase in AST and ALT levels, and chest x-ray images of pneumonia MESHD pneumonia HP. All patients are in mild condition. The average length of hospital admission patients to discharge is more than 30 days. Conclusion Although all patients are in mild condition, the inability of a local laboratory to check for positive confirmation of COVID-19 makes the admission period of the patient in the hospital very long. The availability of RT-PCR tests at Abdul Wahab Sjahranie Hospital Samarinda will greatly assist the further management of COVID-19 patients.

    Introduction The coronavirus disease MESHD 2019(COVID-19) is caused by the virus SARS-CoV-2 and is declared as a global pandemic by the World Health Organization (WHO). Various hematological parameters alteration has been documented in the Chinese literature in SARS-Cov-2 infection MESHD. However, there is a need for research to evaluate the pattern of the hematological parameters of COVID-19 patients in the Indian population. Aims & Objectives: The objective of the study is to see the Neutrophil-Lymphocyte Ratio (NLR), Platelet Lymphocyte Ratio (PLR), and other hematological parameters alteration of COVID-19 patients along with their clinical course in the Indian scenario. Methods: A single-center prospective study of 32 patients with laboratory-confirmed COVID-19 admitted to Super Speciality Pediatric Hospital & Post Graduate Teaching Institute NOIDA, from March to April, were enrolled for the study. The demographic data, the clinical status of the patients during admission and follow up, baseline, and follow up hematological findings were recorded. Statistical analysis of the data was carried out, and relevant findings were presented. Results: Demographic characterization shows a mean age TRANS of 37.7 years, male TRANS (41.9%), female TRANS (58.1%)with the majority of patients are mildly symptomatic to asymptomatic TRANS(93%). The CBC values and NLR, PLR at baseline between the male TRANS and the female TRANS patients, are not showing any statistically significant difference as the 95% C.I. A statistically significant increment in the lab parameters is observed in follow-up visits. Conclusion: The majority of the patients are younger and have mild clinical presentation with female TRANS predominance. Pediatric cases have mild symptomology. Baseline CBC findings show mild neutrophilia HP, lymphopenia MESHD lymphopenia HP, eosinopenia, and normal to mild thrombocytopenia MESHD thrombocytopenia HP. An increase in CBC parameters, NLR was noted in follow up cases. Anemia MESHD Anemia HP was not noted in baseline CBC and in the follow-up group. A onetime PLR is not indicative of disease progression MESHD. Key words: Corona virus,COVID-19,CBC,NLR,PLR

    Background The outbreak of coronavirus disease MESHD 2019 (COVID-19) in December 2019 overlaps with the flu season. Methods We compared clinical and laboratory results from 719 influenza and 973 COVID-19 patients from January to April 2020. We compiled laboratory results from the first 14 days of the hospitalized patients using parameters that are most significantly different between COVID-19 and influenza and hierarchically clustered COVID-19 patients based on these data. The clinical outcomes were compared among different clusters. Results Temporal analyses of laboratory results revealed that compared to influenza, patients with COVID-19 exhibited a continued increase in the white blood SERO cell count, rapid decline of hemoglobin, more rapid increase in blood urea nitrogen HP blood SERO urea nitrogen (BUN) and D-dimer, and higher level of alanine transaminase, C-reactive protein, ferritin, and fibrinogen. Using these results, we sub-classified the COVID-19 patients into 5 clusters through a hierarchical clustering analysis. We then reviewed the medical record of these patients and risk stratified them based on the clinical outcomes. The cluster with the highest risk showed 27.8% fatality, 94% ICU admission, 94% intubation, and 28% discharge rates compared to 0%, 38%, 22%, and 88% in the lowest risk cluster, respectively. Patients in the highest risk cluster had leukocytosis MESHD leukocytosis HP including neutrophilia HP and monocytosis HP, severe anemia MESHD anemia HP, higher BUN, creatinine, D-dimer, alkaline phosphatase, bilirubin, and troponin. Conclusions There are significant differences in the clinical and laboratory courses between COVID-19 and influenza. Risk stratification in hospitalized COVID-19 patients using laboratory data could be useful to predict clinical outcomes and pathophysiology of these patients.

    We analyze risk factors correlated with the initial transmission TRANS growth rate of the recent COVID-19 pandemic in different countries. The number of cases follows in its early stages an almost exponential expansion; we chose as a starting point in each country the first day with 30 cases and we used 12 days, capturing thus the early exponential growth. We looked then for linear correlations of the exponents with other variables, for a sample of 126 countries. We find a positive correlation, faster spread of COVID-19 , with high confidence level with the following variables, with respective p-value: low Temperature (4x10 -7), high ratio of old vs. working- age TRANS people (3x10 -6), life expectancy (8x10 -6), number of international tourists (1x10 -5), earlier epidemic starting date (2x10 -5), high level of physical contact in greeting habits (6x10 -5), lung cancer prevalence SERO (6x10 -5), obesity MESHD obesity HP in males TRANS (1x10 -4), share of population in urban areas (2x10 -4), cancer prevalence SERO (3x10 -4), alcohol consumption (0.0019), daily smoking prevalence SERO (0.0036), UV index (0.004, smaller sample, 73 countries), low Vitamin D serum SERO levels (0.002-0.006, smaller sample, 50 countries). There is highly significant correlation also with blood SERO type: positive correlation with types RH- (2x10 -5) and A+ (2x10 -3), negative correlation with B+ (2x10 -4). We also find positive correlation with moderate confidence level (p-value of 0.02-0.03) with: CO2/SO emissions, type-1 diabetes in children TRANS, low vaccination coverage for Tuberculosis MESHD (BCG). Several of the above variables are correlated with each other and so they are likely to have common interpretations. Other variables are found to have a counterintuitive negative correlation, which may be explained due their strong negative correlation with life expectancy: slower spread of COVID-19 is correlated with high death MESHD-rate due to pollution, prevalence SERO of anemia MESHD anemia HP and hepatitis B MESHD hepatitis HP, high blood SERO pressure in females TRANS. We also analyzed the possible existence of a bias: countries with low GDP-per capita, typically located in warm regions, might have less intense testing and we discuss correlation with the above variables.

    ABSTRACT Background: The coronavirus disease MESHD (COVID-19) pandemic is an emerging threat worldwide. It is still unclear how comorbidities affect the risk of infection TRANS risk of infection TRANS infection MESHD and severity of COVID-19. Methods: A nationwide retrospective case-control study of 65,149 individuals, aged TRANS 18 years or older, whose medical cost for COVID-19 testing were claimed until April 8, 2020. The diagnosis of COVID-19 and severity of COVID-19 infection MESHD were identified from the reimbursement data using diagnosis codes and based on whether respiratory support was used, respectively. Odds ratios were estimated using multiple logistic regression, after adjusting for age TRANS, sex, region, healthcare utilization, and insurance status. Results: The COVID-19 group (5,172 of 65,149) was younger and showed higher proportion of females TRANS. 5.6% (293 of 5,172) of COVID-19 cases were severe. The severe COVID-19 group had older patients and a higher male TRANS ratio than the non-severe group. Cushing syndrome MESHD (Odds ratio range (ORR) 2.059-2.358), chronic renal disease MESHD (ORR 1.292-1.604), anemia MESHD anemia HP (OR 1.132), bone marrow dysfunction (ORR 1.471-1.645), and schizophrenia HP (ORR 1.287-1.556) showed significant association with infection MESHD of COVID-19. In terms of severity, diabetes (OR 1.417, 95% CI 1.047-1.917), hypertension MESHD hypertension HP (OR 1.378, 95% CI 1.008-1.883), heart failure MESHD (ORR 1.562-1.730), chronic lower respiratory disease MESHD (ORR 1.361-1.413), non-infectious lower digestive system disease MESHD (ORR 1.361-1.418), rheumatoid arthritis MESHD rheumatoid arthritis HP (ORR 1.865-1.908), substance use (ORR 2.790-2.848), and schizophrenia HP (ORR 3.434-3.833) were related with severe COVID-19. Conclusions: We identified several comorbidities associated with COVID-19. Health care workers should be more careful when diagnosing and treating COVID-19 when the patient has the above-mentioned comorbidities.
