Little is known about the factors that could predict patient literacy of radiology reports, testing, or treatment. This study aims to identify the most important factors of\u0000 health consumer social economic and health conditions as a predictor of health literacy in the radiology domain. The study recruited 616 participants using Amazon.com’s Mechanical Turk (MTURK) and presented\u0000 these participants with our questionnaire. We measured the level of participants’ radiology awareness, social factors, and health status. Descriptive statics including Chi-Square and linear regression models were used to test if the factors could predict radiology literacy. The area\u0000 under the receiver–operator curve was calculated to determine the prediction accuracy of the regression models. linear regression indicated that 15 of the 19 social-economic factors and health conditions were significantly associated with radiology literacy (P < .05). On the\u0000 other hand, only 12 of the 19 factors were significant by using Pearson Chi-Square (P < .05). Stepwise linear regression analysis demonstrated the r squared linear of 9 out of 12 common factors. These factors are the level of education, smoking, radiology experience, insurance status,\u0000 white race, employment status, disability status, gender, and income at 0.209. These nine factors had a good ability to predict radiology literacy (area under the receiver operator curve of 0.677 [95%CI 0.549; 0.804, P = 0.013]). Social economic factors and health conditions can be\u0000 used to successfully predict radiology literacy. We were able to successfully identify the predictive factors that have a high association with the radiology literacy by comparing social factors and health status versus radiology awareness.","PeriodicalId":393031,"journal":{"name":"J.

Luo, Yu Cao, Hengyong Yu","doi":"10.1166/jmihi.2021.3865","DOIUrl":"https://doi.org/10.1166/jmihi.2021.3865","url":null,"abstract":"The outbreak of 2019 novel coronavirus (COVID-19) has caused more than 176 million confirmed cases by June 14, 2021, and this number will continue to grow. Automatic and accurate COVID-19 detection/evaluation from the computed tomography (CT) scans is of great significance for COVID-19\u0000 diagnosis and treatment. Due to individual variations of patients and the influx of a large number of patients, the current clinical practices remain subject to shortcomings of potential high-risk and time-consumption issues from radiologists. In this paper, we propose a computer aided detection\u0000 system to relieve the clinical physicians from tediously reading the CT images of COVID-19 patients. Particularly, a COVID-19 detection network (COVIDNet) is proposed using deep convolutional neural networks (DCNNs) for patient-level COVID-19 detection to distinguish infected and non-infected\u0000 patients. The underlying method complementarily and comprehensively extract multi-level interplane volumetric correlation features of typical ground glass opacities (GGOs) lesions using 3D multi-Scale Network (MSN). To cover more GGO lesion features and reduce intra-class differences, a Phase\u0000 Ensemble (PE) is proposed for aggregation of different phases in one CT scan. The proposed method is evaluated on a clinically established COVID-19 database with five-fold cross-validation. Experimental results show that the proposed framework achieves classification performance with the specificity\u0000 of 1.0000, sensitivity of 0.9700, accuracy of 0.9850, precision of 1.0000, and Area Under the Curve (AUC) of 0.9980. All of these indicate that our method enables an efficient, accurate and reliable patient-level COVID-19 detection for clinical diagnosis. This can significantly improve the\u0000 work efficiency of clinical physicians on COVID-19 patient diagnosis and evaluation in hospitals and clinics. Impact statement—The proposed method can automatically and accurately distinguish the COVID-19 patients from patient-level CT scan images.

Arrhythmia is a persistent CHD with high mortalities resulting from cardiac failures, heart strokes, and CADs (Coronary Artery Diseases). Arrhythmia can be detected using ECG (Electrocardiogram) signals. ECG signals\u0000 need to be pre-processed for removing noises present in signals. Since denoising is a significant step in ECG signals. Recently Support Vector Machine -Radial Bias Function (SVM-RBF) classifier is introduced for arrhythmia classification, it doesn’t remove noises presented from the ECG\u0000 signals. The major aim of the work is to design a new classifier with removed noises and enhanced ECG signal. In this work, EMDs (Empirical Mode Decompositions) is introduced for noise removing which works recursively and dependent on signals called sifting. In EMD, IMFs (Intrinsic Mode Functions)\u0000 decompose noisy signals into intrinsic oscillatory components adaptively using sifting. Further, FWBSOs (Fuzzy Weight Beetle Swarm Optimizations) are used in this work for optimizing EMDs and IMFs. This work in the initial phase reconstructs ECG signals which are filtered by IMFs. These filters\u0000 are followed by extraction of morphological features from waves of P-QRS-T while ECG segments are selected using PCAs and DTWs. In the final phase, EKSVMs (Enhanced Kernel Support Vector Machines) classifies extracted features automatically by categorizing ECG signals into Normal and Ventricular\u0000 Ectopic Beats. This work’s resulted are evaluated with performance metrics of Sensitivity, F-measure, Positive Productivity and Accuracy. This work uses database of MIT-BIH arrhythmia in a 5 fold cross validation for its predictions. The proposed EKSVMs classifier is compared to existing\u0000 classifiers such as K-Nearest Neighbors (KNN), Enhanced Particle Swarm Optimisation-Multiple Layer Perception (EPSO-MLP) and SVM-RBF.
