OBJECTIVES: We investigate classification models to differentiate COVID-19-based and typical pneumonia in chest radiography.

METHODS: We use 136 segmented chest X-rays to train and evaluate the performance of support vector machine (SVM), random forest (RF), AdaBoost (AB), and logistic regression (LR) classification methods. We use the PyRadiomics to extract statistical texture-based features in the right, left, and in six lung zones. We use a stratified k-folds (k=5) cross-validation within the training dataset, selecting the most relevant features with validation accuracy and relative feature importance.

RESULTS: The AB model seems to be the best discriminant method, using six lung zones (AUC = 0.98).

CONCLUSION: Our study shows a predominance of radiomic texture-based features related to COVID-19 pneumonia within the right lung, with a tendency within the upper lung zone.

Research efforts have been intensified all around the humankind.

OBJECTIVE: The main objective of this paper is to study the new pandemic COVID-19 using for the first-time theories of Fuzzy Cognitive Maps (FCM).

METHODS: All known studies for COVID-19 are done based on statistical models. These statistical approaches depend solely on correlation factors. The factor of causality has not been considered due to the luck of sufficient mathematical models based on causality. Correlation does not imply causality while causality always implies correlation. The approach of Fuzzy Cognitive Maps (FCM) that is considering the causality factors is proposed, to investigate the whole spectrum of COVID-19.

RESULTS: Early theoretical simulation studies using a COVID-19 FCM model have been conducted. Simulations with real patient data give excellent results. The state space Advanced Fuzzy Cognitive Maps (AFCM) is the natural sequence of the classical FCM theories.

CONCLUSIONS: This study gives strong evidence that the “generic FCM theories” are probably the only ones that explore the causality between the variables of medical problems in a sound mathematical and scientific foundation.

OBJECTIVES: The purpose of this work is to develop a technique for detecting biomarkers of four possible conditions in chest X-rays, and study the patterns arising from the location of biomarkers.

METHODS: We use transfer learning applied to a pretrained VGG19 neural network to build a model capable of detecting the four conditions in chest X-rays. For biomarkers detection we use Grad-CAM. Patterns in the biomarkers are found by using classical eigenfaces approach.

RESULTS: The discovered patterns are consistent across images from a given class of disease, and they are robust with respect to changes in dataset.

CONCLUSION: The identified patterns can serve as biomarkers for a given disease in chest X-ray images, and constitute explanations of how the deep learning model makes classification decisions.

The world community (i.e. international organizations, public administrations, businesses, and citizens) has conducted a huge effort in delivering digital solutions to properly address the challenges imposed. A multitude of approaches have been followed, towards achieving a wide spectrum of side goals.

OBJECTIVES: This work presents a platform, designed for public health authorities, to effectively track suspect, probable and confirmed incidence cases in a pandemic by means of a mobile app used by citizens to provide immediate feedback.The aim has been to better support human tracers, and the platform must not be confused with proximity tracking apps.

METHODS: The outbreak response tool was developed based on official information and guidelines, on top of an already existing personal health record app which has been extended, to properly accommodate specific needs that emerged during the crisis.

RESULTS: The developed platform provides the framework to support return to the “new normal” in less time, with reduced stress and more security for individuals, more direct and safer management of patients by physicians, and better possibilities for monitoring the epidemic by public health authorities. Issues relevant to privacy concerns, and interoperability with available patient registries and data analytics tools were also examined to better support public healthcare delivery and contain the spread of the infection.

CONCLUSION: In order for the foreseen benefits to be realized, there is a need to respect safety and security regulations, while at the same time conform to international standards and widely accepted medical protocols. Cross-border interoperability and the availability of appropriate links (i.e. publicly available interfaces) to relevant open data and national registries is considered to be of paramount importance.

OBJECTIVES: This study aims at creating a personalized model that combines machine learning and finite element simulation approach in order to predict development of COVID-19 infection in patients.

METHODS: The methodology combines several aspects (1) classification of patients into several classes of clinical condition (2) segmentation of human lungs in X ray images (3) finite element simulation to investigate the spreading of SARS-COV-2 virion in the lungs.

RESULTS: The findings show accuracy larger than 90% in all aspects of methodology. FE simulation has revealed that the distribution of airflow in the lung changes in time with the infection.

CONCLUSION: The key benefit of our proposed method is that it combines several methods that will be further improved in order to create a truly unique combined methodology for predictive models in patients infected with COVID-19.

Scope

EAI Endorsed Transactions on Bioengineering and Bioinformatics (BEBI), formerly EAI Endorsed Transactions on Ambient Systems, aims at building intelligent synergies and systems among Bioinformatics, Computational Biology, Bioengineering and Biomedicine these complementary disciplines that hold great promise for the advancement of research and development in complex medical and biological systems, agriculture, environment, public health, drug design. Research and development in these areas are impacting the science and technology in fields such as medicine, food production, forensics, etc. by advancing fundamental concepts in molecular biology, by helping us understand living organisms at multiple levels, by developing innovative implants and bio-prosthetics, and by improving tools and techniques for the detection, prevention and treatment of diseases. The BEBI will provide a common platform for the cross fertilization of ideas, and for shaping knowledge and scientific achievements by bridging these very important and complementary disciplines into an interactive and attractive forum.
