His chest computerized tomography (CT) showed gas and fluid containing parenchymal collection in the anteromedial right middle lobe measuring up to 4.8 cm, most consistent with a pulmonary abscess. Antimicrobial treatment was started. The patient became hypoxic and was intubated and mechanically ventilated. Bronchoalveolar lavage fluid was positive for galactomannan assay, a diagnostic marker for possible aspergillosis. A repeat chest CT showed a cavitary lesion with a positive air crescent sign, a common CT finding of invasive pulmonary aspergillosis.

Chest X-ray (CXR) imaging has proven reliable, fast, and cost-effective for identifying COVID-19 infections, which presents with atypical unilateral patchy infiltration in the lungs like typical pneumonia. We employed the deep convolutional neural network (DCNN) ResNet-34 to detect and classify CXR images from patients with COVID-19, other viral pneumonias, and normal controls. Methods: We created a single database, containing 781 source CXR images for COVID-19 (n=240), other viral pneumonias (n=274), and normal controls (n=267) from four different international sub-databases: the Società Italiana di Radiologia Medica e Interventistica (SIRM), the GitHub Database, the Radiology Society of North America (RSNA), and the Kaggle Chest X-Ray Database. Images were resized, normalized without any augmentation, and arranged in m batches of 16 images before supervised training, testing, and cross-validation of the DCNN classifier. Results: The ResNet-34 had a diagnostic accuracy as of the receiver operating characteristic (ROC) curves of the truepositive rate versus the false-positive rate with the area under the curve (AUC) of 1.00, 0.99, and 0.99, for COVID-19, other viral pneumonia, and normal control CXR images, respectively. This accuracy implied identical high sensitivity and specificity values of 100%, 99%, and 99% for the three groups, respectively. ResNet-34 achieved identical sensitivity and specificity of 100%, 99.6%, and 98.9% for classifying CXR images of the three groups, with an overall accuracy of 99.5% for the testing subset for diagnosis/prognosis. Conclusion: Based on this high classification precision, we believe that the output activation map of the final layer of the ResNet-34 is a powerful tool for the accurate diagnosis of COVID-19 infection from CXR images.","PeriodicalId":91979,"journal":{"name":"The University of Louisville journal of respiratory infections","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72974554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that the synergistic interaction of COVID-19 and poverty epidemics favors the development of more severe forms of COVID-19 in the population living in poverty. To test this hypothesis, we assessed whether an ecological association exists between the geographic distribution of hospitalized patients with SARS-CoV-2 pneumonia and markers of poverty in the city of Louisville, KY. Methods: Using the geomasked home addresses of hospitalized patients with SARS-CoV-2 pneumonia in the city of Louisville, a kernel density heatmap was created. Kuldorff’s spatial scan statistic was used to calculate areas of increased risk for SARS-CoV-2 pneumonia hospitalization. Heat maps were created for census tract–level demographics according to income, age, race, and ethnicity to assess whether an ecological association exists with the spatial distribution of SARSCoV-2 pneumonia hospitalization. Results: Four areas of increased risk of hospitalization due to SARS-CoV-2 pneumonia were identified in the western and central sections of the city, with relative risks (RRs) ranging from 2.3 (95% confidence interval (CI): 1.7–3.0) to 3.2 (95% CI: 2.1–5.0) (p<0.001 for each area). Most high-risk areas were associated with areas of the city with low-income populations and black and Hispanic communities but were not associated with areas of older adults. Conclusion: Residents from low-income areas are almost three times more likely to develop SARS-CoV-2 pneumonia requiring hospitalization. Current efforts to decrease the number of COVID-19 hospitalizations through vaccination of populations at risk should be concentrated in city areas with a low-income level population.

While a number of studies have reported an increased risk associated with blood type A and a reduced risk with type O, other studies have did not found a significant effect. This study aimed to define the prevalence of different ABO blood groups in hospitalized COVID-19 patients in the Louisville, KY area and to investigate whether an association exists between the blood group and disease severity. Methods: This was a retrospective observational study of 380 patients with SARS-CoV-2 infection hospitalized to eight of the adult hospitals in the city of Louisville. Patients were divided into four different groups according to their ABO blood type. Demographic characteristics and clinical variables, including laboratory data as well as clinical outcomes were compared. Results: Type O was the most common blood group among the hospitalized patients (51%) followed by type A (31%), B (14%) and AB (4%). The observed blood group distribution among the patients was not significantly different from the distribution expected when compared to a population of similar racial/ethnic composition. No significant associations were found between the blood group and comorbidities, inflammatory biomarkers as well as with recorded outcomes, including the mortality rate and the length of the hospital stay. Conclusions: The data from hospitalized patients in Louisville is is not consistent with the ABO blood group having a significant effect as a risk or severity factor for COVID-19, but it is representative in COVID-19 or its severity of its prevalence among different racial/ethnic populations.","PeriodicalId":91979,"journal":{"name":"The University of Louisville journal of respiratory infections","volume":"80 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83400390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a lack of consensus as to how the clinical outcomes of African American patients differ from those of other groups. The objective of this study was to define the clinical outcomes of African American and White hospitalized patients with SARS-CoV-2 community-acquired pneumonia (CAP) in Louisville, Kentucky. Methods: This was a retrospective cohort study of hospitalized patients with SARS-CoV-2 CAP at eight hospitals in Louisville, Kentucky. Severity of CAP at time of hospitalization was evaluated using the pneumonia severity index (PSI), CURB-65 score, SARS-CoV-2 viral load, and the World Health Organization severity score. The following thirteen clinical outcomes were compared: discharge alive to home, time to home discharge, admission to the ICU, length of ICU stay, need for invasive mechanical ventilation (IMV), duration of IMV, development of acute respiratory distress syndrome (ARDS), development of septic shock, need for vasopressors, development of cardiovascular events, time to cardiovascular events, in-hospital mortality, and time to death. Results: A total of 541 patients were eligible for this study, 343 White (63%) and 198 African American (37%). None of the thirteen clinical outcomes were significantly different between the two groups. Conclusion: This study indicates that African American and White patients do not have different clinical outcomes after the point of hospitalization due to SARS-CoV-2 CAP.
