    Blacks/African Americans are overrepresented in the number of hospitalizations and deaths from COVID-19 in the United States, which could be explained through differences in the prevalence SERO of existing comorbidities. We performed a disease-disease MESHD phenome-wide association study (PheWAS) using data representing 5,698 COVID-19 patients from a large academic medical center, stratified by race. We explore the association of 1,043 pre-occurring conditions with several COVID-19 outcomes: testing positive, hospitalization, ICU admission, and mortality. Obesity HP Obesity MESHD, iron deficiency anemia HP iron deficiency anemia MESHD and type II diabetes were associated with susceptibility in the full cohort, while ill-defined descriptions/complications of heart disease MESHD and stage III chronic kidney disease HP kidney disease MESHD were associated among non-Hispanic White (NHW) and non-Hispanic Black/African American (NHAA) patients, respectively. The top phenotype hits in the full, NHW, and NHAA cohorts for hospitalization were acute renal failure MESHD, hypertension HP hypertension MESHD, and insufficiency/arrest respiratory failure MESHD arrest respiratory HP failure, respectively. Suggestive relationships between respiratory issues and COVID-19-related ICU admission and mortality were observed, while circulatory system diseases showed stronger association in NHAA patients. We were able to replicate some known comorbidities related to COVID-19 outcomes while discovering potentially unknown associations, such as endocrine/metabolic conditions related to hospitalization and mental disorders MESHD related to mortality, for future validation. We provide interactive PheWAS visualization for broader exploration.

    Although it has been reported that coexistent chronic diseases MESHD are strongly associated with COVID-19 severity, investigations of predictors for SARS-CoV-2 infection MESHD itself have been seldom performed. To screen potential risk and protective factors for SARS-CoV-2 infection MESHD, meta-regression of data from worldwide nations were herein conducted. We extracted total confirmed COVID-19 cases in worldwide 180 nations (May 31, 2020), nation total population, population ages TRANS 0-14/65 and above, GDP/GNI per capita, PPP, life expectancy at birth, medical-doctor and nursing/midwifery-personnel density, hypertension HP hypertension MESHD/ obesity HP obesity MESHD/ diabetes MESHD prevalence SERO, annual PM2.5 concentrations, daily ultraviolet radiation, population using safely-managed drinking-water/sanitation services and hand-washing facility with soap/water, inbound tourism, and bachelor's MESHD or equivalent (ISCED 6). Restricted maximum-likelihood meta-regression in the random-effects model was performed using Comprehensive Meta-Analysis version 3. To adjust for other covariates, we conducted the hierarchical multivariate models. A slope (coefficient) of the meta-regression line for the COVID-19 prevalence SERO was significantly negative for population ages TRANS 0-14 (-0.0636; P = .0021) and positive for obesity HP obesity MESHD prevalence SERO (0.0411; P = .0099) and annual PM2.5 concentrations in urban areas (0.0158; P = .0454), which would indicate that the COVID-19 prevalence SERO decreases significantly as children TRANS increase and that the COVID-19 prevalence SERO increases significantly as the obese MESHD and PM2.5 increase. In conclusion, children TRANS (negatively) and obesity HP obesity MESHD/PM2.5 (positively) may be independently associated with SARS-CoV-2 infection MESHD.

    Background: Since December 2019, the outbreak of COVID-19 has spread quickly and thumped many countries and regions. The epidemic of central China was under the spotlight and attracted much more attentions. However, there are few reports describing COVID-19 patients in the regions outside of Wuhan, which are undergoing the change from sporadic imported cases to community-acquired transmission TRANS.Methods: The electronic medical records of 74 laboratory-confirmed patients of COVID-19 were retrospectively reviewed and analyzed. Their epidemiological, demographic, clinical and radiological characteristics were systematically summarized. The difference between severe patients and non-severe patients were also analyzed statistically.Results: The 74 COVID-19 patients were composed of 4 (5.4%) mild patients, 56 (75.7%) common patients, 13 (17.6%) severe patients and 1 (1.4%) critical patient. 43 were male TRANS, and 31 were female TRANS, with the average age TRANS 48.1±17.5. No significant difference of susceptibility was observed between genders TRANS, and almost people with all age TRANS were susceptible to SARS-CoV-2 infection MESHD. Before Jan 26, only imported sporadic cases were observed. However, from that day onward, family cluster infection MESHD cases increased dramatically, up to 70.3% (52/74), which were mainly from 15 family. The incubation period TRANS spanned from 0 to 19 days, with the median 5, and 81.4% had symptom onset TRANS within 7 days. At admission, 31.1% of patients had underlying diseases MESHD and the most common underlying diseases were hypertension HP hypertension MESHD (13.5%) and diabetes MESHD (5.4%). The most common symptoms were fever HP fever MESHD (90.5%), cough HP (75.7%), fatigue HP fatigue MESHD (36.5%) and chest distress (32.4%). 36.5% and 16.2% of patients had leukopenia HP leukopenia MESHD and lymphocytopenia MESHD. 43.2% of patients had increased C reactive protein (CRP), and 40.5% had higher erythrocyte sedimentation rate (ESR) and 21.6% had higher calcitonin. 74.3% of patients had obvious lesions in both lung lobes MESHD and 56.8% of lesions manifested as ground glass opacity. Compared with non-severe group, the severe/critical group were significantly older and had more underlying diseases. After treatment, all patients improved and were discharged. No medical professional infection MESHD and death case were reported.Conclusion: The epidemic of COVID-19 in Nanjing were mainly caused by family cluster infection MESHD. The entire prevalence SERO and illness were much milder than those of Wuhan. The disease of COVID-19 could be controlled and cured.
