  • ICG signal noise cancellation algorithms for non-invasive hemodynamic monitoring   Order a copy of this article
    by Hadjer Benabdallah, Salim Kerai 
    Abstract: Impedance cardiography (ICG) non-invasive technique is a new way in the medical field, used for diagnosis and monitoring of cardiovascular disorders. The signal processing domain developed several denoising techniques applied for the cancellation of respiratory and movements' artefacts that corrupted the acquired signal shape. For this main purpose, our paper-based on a comparative study between different type of adaptive filters and Savitzky-Golay (SG) filtering, those are applied to the sensed impedance to noise removal for hemodynamic parameters monitoring. The results demonstrated in this work are more suitable; it confirmed that the proposed SG denoising filter outperformed the other techniques cited in state-of-art in terms of preserving information carried over on the signal when the mean error rate of the SG technique is equal to 0.00038%.

  • Improving prediction of one-year mortality of acute myocardial infarction using machine learning techniques   Order a copy of this article
    by Mirza Touseef, Najla Raza, Adeel Zafar, Muhammad Zubair, Saad Zafar 
    Abstract: The purpose of our study was to improve the prediction of one-year mortality for patients with acute myocardial infarction (AMI). We implemented and compared four classical machine learning algorithms and one deep neural network algorithm. For evaluation metrics, we used accuracy, F1-measure, precision, recall, and area under the receiver operating characteristic curve (AUC). Random forest achieved the best performance based on an AUC of 0.98 with an accuracy of 92%. Results show that our model can predict one-year mortality of AMI with an improved AUC and accuracy using a minimum number of features as compared to previous related studies.

    by Ayoub Bouslah, Nora Taleb 
    Abstract: Parkinsons disease (PD) is become the second most neurological syndrome of the central nervous system after Alzheimers disease. It causes diverse symptoms which include bradykinesia (slowness of movement), voice impairments, rigidity, tremor, and poor balance. The PD recognition system based on voice is founded a noninvasive alternative, but involves rather complex measurements or variables. Therefore an attention is required toward new approaches for better forecasting accuracy. In this paper, an optimal Fast Learning Network (FLN) based on genetic algorithm (GA) was established as PD Diagnosis system. FLN is a double parallel feed-forward neural network structure, as a matter of fact, GA for features reduction and hyperparameters optimization of the FLN which is used as a predictive model. Finally, the conducted experiments on the Parkinson data of voice recordings over Ten Fold Cross-Validation show that proposed system is less complex and also achieved better average classification results with an accuracy of 97.47 %. At the same time, its effective in automatic identification of important vocal features. Moreover, the highest average degree of improved accuracy was (2.1 %) compared with other familiar wrappers including Support Vector Machine and K-nearest Neigbors in the similar conditions.

    Abstract: Though effect coronavirus has known to be a catastrophic pandemic since 100 of years, Severe Acute Respiratory Syndrome-2 coronavirus (SARS2-CoV) was first claimed to be emerged in December 2019 at the city of Wuhan, China. Abruptly, the virus dominated more than 218 countries with 157,566,607 confirmed cases and the death figure has reached nearly 32,84,551 till time. Recently the pandemic is getting worse day by day, people are suffering from hypoxia and server respiratory problem despite of the unstoppable service of healthcare sector. Prior concern behind this emergency is that, till date researchers and scientists were failed to invent any productive pharmaceutical treatment to weed out the infection completely. Although, vaccination is publically available; but it is applicable only for precaution purpose and not evident for preventive measures. This review focuses on therauptiuc status to control the severity of SAS2-CoV agent. The approach aims at implicating a low toxic metabolite anti-malarial drug, Hydroxychloroquine combined with an antibiotic called Azithromycin for the treatment of acute respiratory disturbance and hypoxia. This article briefly demonstrates the phramaco-potential of both these medications, their effects on patients based on a clinical observation and ongoing status of dosage to validate its implication.

  • Identification of stroke using deepnet machine learning algorithm   Order a copy of this article
    by Abdulwahhab Alshammari, Noorah Atiyah, Hanoof Alaboodi, Riyad Alshammari 
    Abstract: Stroke is a disease that impacts individuals of all races, genders, and backgrounds. To combat the rising prevalence of the disease, the creation of accurate diagnostic tools is paramount. This paper uses two machine learning models, deepnet and decision tree, to assess the health record data from the Ministry of National Guard Health Affairs, Saudi Arabia. Deepnet outperformed the decision tree in accurately predicting stroke and stroke mimic. Deepnet achieved an accuracy of 92.35%, while decision tree achieved 90.8%. Future application of machine learning on stroke and stroke mimic diagnosis holds great potential in public health reform, patient empowerment, and minimising healthcare burden. This paper proposes building a national centralised semi-detection stroke data management framework to create a national platform in the diagnoses, acute, and long-term treatment of stroke.

  • Identification and classification of schizophrenic speech using convolutional neural network for medical healthcare   Order a copy of this article
    by Akshita Abrol, Nisha Kapoor, Parveen Kumar Lehana 
    Abstract: Schizophrenia is a brain disorder that significantly affects the quality of life of affected individuals. One of its prominent symptoms is the induction of changes in the acoustics of the patients. In the absence of definite methods for its diagnosis, speech analysis can help in the preliminary screening of the patients. In this paper, an automated method using deep learning for differentiating between individuals with schizophrenia and psychosis from healthy individuals is suggested. Using convolutional neural networks with speech spectrograms as input, a classification accuracy of 87.01% has been obtained for levels of schizophrenia and 95.26% for differentiating between schizophrenic and healthy speech.
    Keywords: schizophrenia; convolutional neural network; CNN; deep learning; spectrograms.

  • CIAE: class imbalance aware ensemble framework to predict drug side effects   Order a copy of this article
    by Kanica Sachdev, Manoj Kumar Gupta 
    Abstract: The binding of the drug compounds to certain biological off target proteins causes undesirable side effects or drug toxicology. The determination of drug toxicology at the early steps of drug development would help to economise on money as well as time. The paper proposes a novel framework, class imbalance aware ensemble (CIAE), for the identification of drug side effects using ensemble learning. It employs the related side effect information of the drugs to predict novel side effects. An eminent cause of the low performance of the machine learning based methods is the presence of class imbalance in the data. The proposed framework efficiently addressees this issue to improve the predictor performance. A comprehensive comparison of the method with the state of the art classifiers shows that the proposed framework yields better results for drug side effect determination.

  • An overview of early detection of Alzheimer's disease   Order a copy of this article
    by C.R. Nagarathna, Kusuma Mohanchandra 
    Abstract: Alzheimer's disease is a most common neurodegenerative brain disease characterized by a problem in thinking and loss in cognition memory judgment. One of the difficult tasks is to identify symptoms of Alzheimer's at its beginning stage. Once the disease is detected it is very serious to save the life of a patient. The current medical treatments cannot cure Alzheimer's but its early diagnosis can stop the progress of disease and make the patient lead their life. So it is necessary to diagnose Alzheimer's at an early stage using different modalities like EEG, MRI, and PET as they provide more promising results compared to a single modality In this paper, the progression symptoms, causes, modalities, and methods used for finding Alzheimer's disease is reviewed. The state-of-the- art literature is reviewed and the gaps identified in the literature are discussed.

  • Multi-task deep neural network models for learning COVID-19 disease representations from multimodal data   Order a copy of this article
    by Veena Mayya, K. Karthik, Krishnananda Prabhu Karadka, S. Sowmya Kamath 
    Abstract: Over the continued course of the COVID-19 pandemic, a significant volume of expert-written diagnosis reports has been accumulated that capture a multitude of symptoms and observations on diagnosed COVID-19 cases, along with expert-validated chest X-ray scans. The utility of rich, latent information embedded in such unstructured expert-written diagnosis reports and its importance as a source of valuable disease-specific information has been explored to a very limited extent. In this work, a convolutional attention-based dense (CAD) neural model for COVID-19 prediction is proposed. The model is trained on the rich disease-specific parameters extracted from chest X-ray images and expert-written diagnostic text reports to support an evidence-based diagnosis. Scalability is ensured by incorporating content based learning models for automatically generating diagnosis reports of identified COVID-19 cases, reducing radiologists’ cognitive burden. Experimental evaluation showed that multimodal patient data plays a vital role in diagnosing early-stage cases, thus helping hasten the diagnosis process.

  • Biothermodynamics may be a highly useful tool to help medical practitioners to detect and cure morbidities   Order a copy of this article
    by Mustafa Özilgen 
    Abstract: Biothermodynamics may help clinicians to diagnose and cure many medical cases, slow down ageing, correct malnutrition and repair the distorted tissues. Thermodynamically detected decrease in cardiac or renal filtration efficiencies indicate a malfunctioning system. Thermodynamic assessment of the circulatory system after amputation and restoring the circulatory pressure drop may prevent deaths. Research on thermodynamics of fertilisation may help to medical practitioners to fight against infertility. Athletes of some sports have substantially shorter lifespan than the other people. Biothermodynamics may offers some help to those athletes via prescribing appropriate energy intake. Distortion of the energy management in the body is observed in various health problems, including cancer. The need for multidisciplinary research to achieve additional understanding of these phenomena has been suggested by numerous researchers. Biothermodynamics may offer the best tool to achieve this goal.

  • A conceptual model to improve the patient flow during COVID-19   Order a copy of this article
    by Abdesselam Bougdira, Asmae Mazti, Hayat Sedrati, Fayssal Jhilal, Saaid Amzazi, Chakib Nejjari, Hassan Ghazal 
    Abstract: In the COVID-19 context, hospitals across the globe endeavour to manage the unprecedented flow of patients. Challenges are related to the unexpected increase in patients, extra waiting time for cleaning and decontamination of inpatient beds, congested queueing in treatment areas, and waiting time in crowding rooms. This research introduces a new conceptual model to bring a broader, patient-centred, and traceability-based view of patient flow in a clinical setting in the context of COVID-19. The model design opts for four interrelated modes procedural, technical, operational, and contextual. These modes lay the basis of a patient flow solution before starting its development. The feasibility of the proposed model is shown through a usage scenario and developed user interfaces. Results have shown that a knowledge representation of the patient’s real-time information can enable better patient flow monitoring. In addition, it would support intelligent healthcare systems that reuse and share pieces of declarative knowledge. Such functionality would enhance the management of patient flow and improve dealing with the patient flow challenges imposed by the COVID-19 pandemic. Moreover, the presented proof of concept laid the ground for future applicability in various clinical settings facing similar infectious disease crises.

  • Detecting obstructive sleep apnea by extracting multimodal HRV features using ensemble subspace discriminant classifier   Order a copy of this article
    by Nivedita Singh, R.H. Talwekar 
    Abstract: Obstructive sleep apnea disorder is very peculiar sleep disorder which is triggered because of rapid and repeated transition of breathing. Hypopnea is also known as partial blockage of respiration during sleep. Polysomnography is gold standard to detect OSA but it is very expensive and complex which motivates us to detect OSA through multimodal heart rate variability (HRV) feature analysis using single channel ECG. The comparison among three classifiers SVM, weighted KNN and ensemble subspace discriminant are investigated for OSA detection. The accuracy obtained by the ESD classifier is 100%. True positive rate (TPR) and the true negative rate (TNR) have been attained 100% which is best suitable classifier for our experiment.

    by Rekha Rajagopal, V. Shyam Kumar 
    Abstract: Cardiac arrhythmia is a condition in which the heart beats at a faster rate or a slower rate instead of a regular rhythm. Medical professionals identify the category of cardiac arrhythmia by manually viewing the electrocardiogram (ECG) signal which is more time-consuming. There are possibilities of incorrectly identifying the arrhythmia categories due to practical difficulties in manually assessing the slight variations in the amplitude of ECG signals. This research work focuses on automatically categorising the heartbeats as normal beat, supraventricular beat, ventricular beat, fusion beat, and unknown beat using convolutional neural network. The class imbalance problem that arises because of a few numbers of heartbeats in certain arrhythmia categories is resolved using techniques such as synthetic minority oversampling technique (SMOTE), borderline SMOTE, SVM-SMOTE, and adaptive synthetic sampling (ADASYN). The proposed model demonstrates an average accuracy of 97.76 % in classifying arrhythmia classes using ADASYN technique. This model can help medical professionals in accurately diagnosing the arrhythmia classes.

    by Y. Mahesha, C. Nagaraju 
    Abstract: The present article has proposed a machine learning method to detect congenital heart diseases (CHDs) such as atrial septal defect (ASD) and myocardial infarction (MI) based on the frequency of occurrence of palm patterns such as ulnar loop and whorl. The system has been developed based on SSD-MobileNet to detect ulnar loop and whorl patterns on palm image. The developed system has achieved an accuracy of 99.28% and 97.19% in the detection of ulnar loop and whorl respectively. Further, the work has been carried out to fix the threshold value on the number of ulnar loop and whorl patterns to detect CHDs such as ASD and MI. The receiver operating characteristic curve has been drawn and the area under curve is calculated for the detection of ASD and MI. These results have shown that the proposed method can be used as a screening model to detect ASD and MI.

    by Y. Mahesha, C. Nagaraju 
    Abstract: This paper proposes a machine learning method to detect congenital heart diseases (CHDs) using a palm pattern known as axial triradius. This article spreads light on three things. First, Faster R-CNN Inception v2 has been used to identify triradii on the palm image. Secondly, a novel spatial method has been proposed to select leftmost, rightmost and axial triradii. Finally, the angle at axial triradius has been calculated on the palm images of healthy people and of patients suffering from tetralogy of Fallot (TOF), atrial septal defect (ASD), ventricular septal defect (VSD) and coarctation of aorta (CoA). The result shows that the proposed method can be used as a screening method to predict CHDs.

  • Feasibility of automatic differential diagnosis of endodontic origin periapical lesions - a pilot study   Order a copy of this article
    by Jay Patel, Dinesh Mital, Vaishali Singhal, Shankar Srinivasan, Huanmei Wu, Sashi Mehta 
    Abstract: Periapical dental diseases (PDD) are one of the most prevalent dental diseases leading to tooth loss and poor quality of life. Differential diagnosis of periapical diseases is critical because the treatment plan depends on the diagnosis. The current diagnosis approach of PDD uses an eyeballing method mainly depending on clinicians’ expertise, any lack of which may lead to an inaccurate diagnosis. We developed an advanced image processing tool that can help clinicians for more accurately differential PDD diagnoses that leads to the correct treatment approach. Sixty periapical radiographs were processed by the tool and the differential diagnostic output was compared with manually annotated gold standard dataset. Our tool performed well with a 95% sensitivity, 89% specificity, and 93% accuracy in providing a differential diagnosis. Demonstrating such promising results, further studies should test the accuracy of this tool on a larger dataset get more definitive results for widespread deployment and use.

    by Akanksha Kaushik, Jyotsna Singh, Shilpa Mahajan 
    Abstract: Although, Amyloid beta (B-amyloid) and neurofibrillary tangles are the assay mark of Alzheimer’s disease (AD), cognitive decline is best concerned with synaptic loss, rather than tangles or plaques. The pyramidal neurons in Hippocampus are highly affected by AD. Therefore, pyramidal neurons are prime focus in our study. Pyramidal neurons have extensively developed calcium signalling, a phenomenon that controls the neuronal rhythms desirable for memory processing and cognition, for regulating wide range of functions like controlling rhythmic activities, information processing and memory binding. The focus of our work is to inspect the impact of B-amyloid on calcium signaling and progression of AD through computational study.

    Abstract: The COVID-19 pandemic has a severe adverse impact on people’s health, lives, and the worldwide global economy. It is only possible to identify positive COVID-19 instances if each country carries out sufficient tests. As suggested in prior studies, X-Ray images could be used as testing samples to develop a reliable and low-cost COVID-19 testing model. This paper introduces a deep learning-based end-to-end binary classification framework, Att-Net, for automated detection of COVID-19 cases using Chest X-ray images. In this work, we have adopted pre-trained ConvNet (VGG-16) with an attention module embedded with the VGG-16 architecture, which significantly improves the model’s performance. The proposed architecture is evaluated on the COVID-Xray-5k dataset. The suggested methodology obtains a state-of-the-art sensitivity of 98.5% and specificity of 99.4%. This work also presents a detailed performance analysis in terms of accuracy, sensitivity, specificity, precision, recall, and F-score. Furthermore, we have also generated the heat maps, which reveal the most anticipated regions infected by COVID-19 while learning for prediction by the CNN to validate the proposed architecture.

    Abstract: Globally, COVID-19 has drastically derailed the clinical care for outpatient services. Healthcare professionals (HCPs) used various specially designed tele-health applications (THA) to cater to the needs of patients. We attempted to explore the barriers and facilitators in utilising THAs as part of a multi-state and multi-disciplinary exploratory sequential mixed methods study. Our study comprised of initial survey of HCPs using quantitative Google Forms Survey tool followed by personal (physical and phone-based) interviews of 30 selected/consented HCPs. Of the 98 HCPs responded to the survey, ~60% of had 1-2 telehealth consultations/day during the pandemic. Approximately 61% of the consultations were limited to < 60 minutes interactions. Less than half were obtaining consent and only one third were maintaining digital log record. Most of the younger HCPs especially women have continued their services through THAs and felt that THAs will continue in the future. Besides the limitations of generalisability, the results suggest enormous scope for THAs in future towards simplifying the processes for effective healthcare service delivery at lesser cost and time.

    Abstract: Diabetic macular oedema (DME) and age-related macular degeneration (AMD) are the leading causes of blindness in adults. The most significant signs of these diseases are appearance of exudates and change of retinal layer structure. Screening of these diseases is very important to prevent vision loss. In this work, a new method based on a genetic k-means algorithm for lesions detection is proposed. From the selected region of interest (ROI), four textural features are extracted and used to classify these two retinal diseases against the normal subjects using the SD-OCT images. From the experimental results found, the SVM gives better results for AMD and DME recognition. The mean accuracy, sensitivity and specificity values for the macular regions classification are 99.67%, 100% and 99.51% respectively.

    Abstract: Neonatal seizures are a common emergency in the neonatal intensive care unit and their detection using electroencephalography (EEG) recording is one of the biggest challenges that neurologists face. Even though using artificial intelligence methods such as deep learning for computer vision can help to solve these problems, time consumption, complexity, and overfitting or underfitting of the model still limit the application of deep learning. In order to produce a real-time system that can detect neonatal seizures using EEG and solve the problem of the lack of availability of neurologists, a convolution neural network-based marine predator algorithm system is proposed.

    by Munshi Rejwan Ala Muid, Afrin Jubaida, Md. Mehedi Hasan Onik, Hamim Hamid 
    Abstract: Electronic health record (EHRs) demands the highest privacy and security as the accuracy of medical research and service largely depend on the integrity of it. Intruders can tamper sensitive protected health information (PHI) or personally identifiable information (PII) purposefully. This study aims to use blockchain technology to build a complete EHR sharing and tracking system, such that even after access is granted to researchers or medical personnel, EHRs remain unaltered and the identities of patients are hidden. This work uses a traditional cloud storage system to store information while saving the indexes of EHRs in a chain to ensure PHI integrity. Additionally, the data sharing is secured by applying a randomly selected data de-identification method that guarantees integrity and trackability of user data anonymously. Finally, this work demonstrates a complete architectural implementation (using Hyperledger and a private blockchain network) of the proposed EHR sharing and access controlling by using two levels of chain (two distinct ledgers) that ensures an efficient sharing platform of PHI.

    by Vinod Arunachalam, N. Kumareshan 
    Abstract: The most used non-invasive diagnostic technique for a wide range of cardiac disorders is an ECG, which records the heart’s electrical activity over time. Compressed ECG signals are a necessary part of most electronic health systems to store and transmit data across long distances. The field programmable gate array (FPGA), a high-speed parallel compute unit, and customisable software capabilities are available with reconfigurable architecture. Consequently, this architecture is suitable for devices like ECGs, which require precise real-time computing for multi-channel signal processing. The Xilinx Zynq 7.000 SoC development board used in this work has an FPGA-based reconfigurable signal processing unit. When compressing data, the method uses fast fourier transformation (FFT). It is possible to achieve a 90% compression rate with this system running in real-time and with minimal to no signal distortion. This method is also the only one in the industry that can reduce high-frequencynoise.

  • FoodKnight: a mobile educational game and analyses for obesity awareness of children   Order a copy of this article
    by Thomas Baily, Fadi Thabtah, Marcus Wright, Duy Anh Tran 
    Abstract: One of the main contributing factors towards child obesity is deficient education regarding food choices. In most cases, children will choose energy-dense foods over those with more nutritional value, without understanding the consequences of their decisions. To help overcome this problem, this paper proposes and assesses the efficacy of an educational gaming application called FoodKnight. Games have the ability to engage children more than traditional teaching schooling methods. FoodKnight incorporates stealth learning to disguise the teaching of healthy food choices while playing a game, while simultaneously incorporating a step-counter to encourage the user to be active. Survey results received from 38 participants regarding the initial prototype have been positive, with minor issues being addressed in an upcoming update. FoodKnight has been shown to be an effective tool for subconsciously conditioning children to make healthier choices.

This study describes a software strategy for detecting brain irregularities to diagnose Alzheimer’s disease. The suggested method creates a 3D model of the brain using MRI slices. This method is more precise and reliable. In this research, we proposed two strategies. To extract radiological data from MRI images, image processing and machine learning were utilised, and a deep learning approach was applied to analyse the condition of Alzheimer’s disease. The algorithm normalises and removes the skull from the MRI images in the first phase. Using a modified K-Means approach, the image is split into white matter (WM), grey matter (GM), and black holes (BH). The classifier is trained using the training data to predict the test data. The characteristics are defined using naive Bayes to create a classification model.

    by Juluru Anudeep, Shriram K. Vasudevan, T.S. Murugesh 
    Abstract: This paper addresses a potential concern faced by the majority of aged ones left unaccompanied at home. Any untoward fall owing to poor health conditions or slippery floors that are more prevalent among the elders happen, it usually goes unnoticed and the aged ones are deprived of the potentially life saving 'golden hour' treatment. To mitigate such sort of problems faced by the elderly, we have designed a wrist-wearable fall detection system that employs a machine learning model for movement tracking and to detect a fall just in case. During a fall, an automated call is generated to the emergency services as well as to a caretaker through a GSM module. Two datasets are collected, trained and tested on seven different machine learning models, and the results presented.

    by S. Seenuvasamurthi, S. Ashok, B. Shankarlal, A. Mohamed Abbas, Ashok Vajravelu 
    Abstract: New perspectives on brain structure and function can only be gained through the rapid advancement of brain imaging technology. Throughout history, this has been the case. It is common practise in medicine to employ image processing in the early stages of diagnosis and treatment. In classification and segmentation tasks, deep neural networks (DNNs) have so far proven to be exceptional. Functional ultrasound (fUS) is a novel imaging technique that enables the observation of neuronal activity across the brain in awake, ambulatory rats. To achieve adequate blood flow sensitivity in the brain microvasculature, fUS relies on lengthy ultrasonic data collecting at high frame rates, placing a load on the sampling and processing hardware. Parallel MRI is introduced in broad terms, with an emphasis on the classical understanding of image space and k-space-based techniques.

    by M. Kamesh, C. Augustine, D. Sarathy, S. Leopauline, Sheshang D. Degadwala 
    Abstract: Parkinson’s disease can be diagnosed using computer-assisted diagnosis systems based on brain imaging, with the ultimate goal of finding patterns that characterise the disease. In this case, convolutional neural networks (CNNs) have proven to be extremely beneficial. Neurological disease Parkinson’s disease (PD) is characterised by a decrease in the brain’s dopamine-producing neurons. Patients with Parkinson’s disease have difficulty producing speech due to a lack of coordination in the muscles that control breathing, phonation, articulation, and prosody, among other things. Speech analysis can be used by clinicians to objectively assess the severity of Parkinson’s disease in a non-invasive manner. In the LSTM layer, the output is then analysed for important temporal feature relationships. Existing state-of-the-art CNN models are compared to the proposed DenseNet-LSTM model. Training accuracy is 93.75%, testing accuracy is 90%, and validation accuracy is 93.87%, according to the suggested model.

    by Ravi Kumar, R. Prabha, B. Kannan, T.J. Nagalakshmi, Sheshang D. Degadwala 
    Abstract: Alzheimer’s disease is a catch-all phrase for a variety of illnesses, including numerous neurodegenerative disorders. A century ago, neurosyphilis-caused dementia was the most frequent cause of dementia in developed nations, but Alzheimer’s disease (AD) is today the most common cause. Dementia might still be difficult to diagnose because of a number of barriers. Early symptoms overlap with other disorders, and the potential of several, or mixed, aetiologies are just a few of the factors that contribute to a wide range of possible outcomes. Because language diminishes along with neurodegeneration in Alzheimer’s disease, it is a significant source of clinical information. As a result, data on speech and language have been intensively investigated in relation to its diagnosis. Text characteristics extracted from the transcripts are used to detect AD using an SVM classifier. However, the accuracy of automatic assessment falls as WER rises, the two are very weakly associated (0.31).

    by P.S. Arthy, A. Kavitha 
    Abstract: Brain image segmentation is one of the processes that take the most time and is the most complicated to do in a therapeutic scenario. The essential principles and features of medical image segmentation based on deep learning are presented. MRI-based medical image classification issues are addressed in this study using a histogram and time-frequency differential deep (HTF-DD) technique. The following are the stages of the proposed approach’s construction. An unsupervised training procedure is used to build a deep convolutional neural network (CNN), which then outputs standardised improved pre-processed features for data extraction. Secondly, a set of time-frequency characteristics is derived from medical images using the time signal and the frequency signal. The last step is to develop an effective model based on differential deep learning for classifying objects. Multi-modal brain data sets and public standards are used to illustrate the applicability of our methodology.

    Abstract: A recent study by the United Nations Agency (World Health Organization) reported that 17.9 million people died due to cardiovascular disease, and it is increasing exponentially. Furthermore, it was also reported that it was highly difficult to recognise the sickness and dictate the relevant care in a timely manner. For analysis, a user data file for cardiopathy prediction that contains parameters such as gender, age, kind of pain, force per unit area, hyperglycaemia, and so on has been considered. The approach entails determining the correlations between the numerous properties of the data file using regular processing techniques and then treating the attributes appropriately to forecast the likelihood of cardiopathy. This article endeavours at probing methodised data-mining techniques such as NB classifier, random forest classification, decision tree in addition to support vector machine. These machine learning approaches require less time to anticipate sickness with a high degree of accuracy. The proposed algorithm provides 91.2% recognition rate than SVM and decision tree classifier.

  • Feature analysis for fundus image classification of multi-retinal diseases   Order a copy of this article
    by Widhia K.Z. Oktoeberza 
    Abstract: Retinal diseases affect the vital eye tissue, which can reduce eye vision and even cause blindness if left undiagnosed and untreated. Some retinal diseases can be prevented and even treated properly to return the lost vision by conducting early detection. A scheme to classify multi-retinal diseases is proposed in this study; specifically diabetic retinopathy (DR), age-related macular degeneration (ARMD), and media haze (MH). The process is starting by extracting some features consisting of statistical and texture features, which are undergone in 500 fundus images taken from the RFMiD dataset. Thereupon, these features were classified based on the MLP classifier. Based on that classification process, the accuracy rate of DR, ARMD, and MH classifications achieved 84.2%, 93.2%, and 89.4%, respectively. These achievements show that the proposed scheme effectively classifies multi-retinal diseases and has the potential to assist ophthalmologists in early detecting the appearance of retinal diseases for preventing the worst effect.

    Abstract: The prevalence of Alzheimer’s disease (AD) is growing dramatically each year, making it critical to find efficient strategies to detect the disease early on and prevent its progression. In this work, we present an approach combining tract-based spatial statistics (TBSS) and convolutional neural network (CNN) to classify the AD and mild cognitive impairment (MCI) from a cognitively normal (CN) subject using the diffusion tensor imaging (DTI). The TBSS was applied to generate the WM skeleton from the two DTI maps fractional anisotropy (FA) and mode of anisotropy (MO). The CNN is trained first on FA-Skeleton and MO-Skeleton and then fine-tuning on FA and MO relevant slices. This combinatory procedure achieved a higher result and represents a powerful diagnostic tool.

    by S. Sathiya Devi, K. Vignesh, V. Raguvaran 
    Abstract: The World Health Organization (WHO) recognises that diabetic retinopathy (DR) is one of the rising healthcare problems in the world which leads to vision loss if left untreated. In this paper, an automated computer aided diagnosis (CAD) system for DR is implemented based on EfficientNet. Initially, image pre-processing is performed by smoothing it with median filter and converting into grey scale image. Then size, colour and shape normalisation are carried out. To increase the volume and to solve the data imbalance issue flipping, rotation, zooming and distortion operations are performed. The CAD system diagnoses the severity levels of DR from fundus images by exploring feature extraction based on EfficientNet B0 model and classification with XGBoost classifier. It is experimented with Indian Diabetic Retinopathy Image Dataset (IDRiD) and experimental result reveals that, the combination of EfficientNet B0 and XGBoost produces better classification accuracy when compared with other convolutional neural network (CNN) models.

    Abstract: A variable that grounds mediation between dependent and independent variables. These mediator variables take vital parts in the analysis of data which entails numerous variables, exclusively when the dependent and independent variables are affected by other variables. Thus, mediation analysis requires all areas which need regression analysis, especially in psychology, industry, teaching, production area, etc. Mediation has been projected in multiple studies. On the other hand, at times it is more logical to articulate the fuzzy theory data when the variables are not purely distinct. Normally, to articulate the attitude of a persona bad, moderate, good use fuzzy numbers than using crisp numbers. This paper explains the model of fuzzy moderated mediation using interval data. Also, to find the total, direct and indirect effects psychological data have been applied when the mediator, moderator, and confounding variable subsist.

    Abstract: A new method of Epilepsy detection and classification of the degree of affliction is presented. The proposed method is based on the information generated by the filled contour maps of the brain MRI. The result is independent of the size and orientation of the target image. Distribution of multiple intensity levels in an MR image is generated by the proposed contour map segmentation technique. Disease afflicted regions are segmented using this technique. The epilepsy diagnosis is carried out by classifying MR images as healthy and diseased. The diseased ones are further classified into three sub-classes of affliction, namely, mild, medium and severe. The classification is based on the area of the top level segment relative to the total area of the non-skull region. In the proposed method, the classification error is found to be between 5% to 10%.

    Abstract: Nowadays, the elderly can receive care in their home and enable physicians to follow their diseases in real-time. However, these technologies suffer from several issues like security and privacy-preserving data challenges. In this paper, we proposed a HIPAA-compliant framework that enables security and privacy-preserving medical data based on fog-to-cloud (F2C) computing. Our aims are to define a system that solves the privacy and security issues with remote elderly monitoring. The F2C infrastructure is used to provide better security of medical data and allow a real-time diagnosis of the elderly. Furthermore, F2C combines the benefits of cloud and fog computing such as providing permanent storage, reducing computation load and data transmission delay, and enhancing the security challenges. Simulation results suggest that F2C technology delivers better performance in terms of latency, cost, and energy consumption.

    Abstract: This paper presents two techniques, histogram equalisation (HE) and contrast limited adaptative histogram equalisation (CLAHE), for contrast enhancement of 2D magnetic resonance imaging (MRI) slices in order to reconstruct them as 3D images. These powerful techniques allow the maximum possible contrast to be established without ultimately affecting medical interpretation, based on a comparative study of three 3D images constructed by the slices: real, enhanced only by HE and those processed by CLAHE after HE. We have experimentally demonstrated that the CLAHE technique is effective in improving contrast and reducing noise amplification especially for medical images.

    by Anwar Ali Yahya 
    Abstract: This paper investigates the problem of detecting adverse drug reactions of anti-epileptic drugs from patients’ reviews in online health communities. A lexicon-based methodology is proposed and applied to a dataset of patients’ reviews collected from two online health communities. The dataset is cleaned and the adverse reactions of anti-epileptic drugs are extracted with the aid of consumer health vocabulary and a lexicon of adverse drug reactions. A proportional reporting ratio is then applied to quantify the correlation between each drug and adverse reactions and thus identify the adverse reactions of each drug. The results are validated quantitatively against a database of adverse drug reactions, called side effect resource, and qualitatively against the extant knowledge related to the common adverse reactions and drug-drug similarities of anti-epileptic drugs. The validation results provide evidences on the effectiveness of the proposed methodology and the validity of online health communities’ data for adverse drug reactions detection.

    by S. Kumarganesh, Muzammil Hussain, H. Shaheen, S. Anthoniraj, M. Somaskandan, C. Sivakumaran 
    Abstract: When attempting to assess spinal cord atrophy caused by a variety of disorders, the first step that must be taken is to segment the spinal cord contour. A tumour of the spinal cord is an abnormal development of cells that may occur anywhere in or around the spinal cord. The process of locating tumours in the spinal cord is a very important one. It is difficult to identify the tumour with MRI due to the irregular form of the spinal cord. The model begins by locating the spinal cord, after which it creates the bounding box coordinates. Our technique is validated using four separate clinical datasets. The results of the experiments that used a unique segmentation strategy that was dependent on MRI images reveal that the algorithm that was presented for the system delivers a higher level of accuracy when compared to the other algorithms that are already in use.

  • Telemetry drug delivery techniques and design. A review   Order a copy of this article
    by Maham Sarvat, Suhaib Masroor, Muhammad Muzammil Khan 
    Abstract: Drug delivery systems (DDS) are developed for the controlled delivery of therapeutic agents. After administration, the DDS releases the active agents, and subsequently, the bioactive molecules are transported across various biological barriers to reach the site of action. Scientists have made a major contribution in understanding the role of various physiological obstacles for the efficient delivery of drugs in the circulatory system and the diffusion of drugs across cells and tissues. This review discusses and compares the drug delivery methods, drug delivery techniques, telemetry drug delivery, mechanical structure of the drug delivery system, and multiple syringes for DDS and also nano-technology drug delivery. The review leads to the conclusion that the wireless drug delivery method overcomes almost all of the drawbacks of the other methods and thus deserves the most attention in future biomedical research.

  • Deep learning-based malignancy prediction in thyroid nodules   Order a copy of this article
    by L. Mohana Sundari, M.S. Maharajan, T. Senthil Kumar, Leo John Baptist Andrews 
    Abstract: Although the vast majority of thyroid nodules are non-cancerous, determining whether or not a nodule is cancerous may be a difficult and time-consuming process that often involves unnecessary surgical events. In addition, we discussed the process of developing a model that might anticipate the presence of cancer in thyroid nodules by including a number of the core demographic and ultrasound parameters. A combined sensitivity and specificity score was used to assess the diagnostic performance, and their accuracy was compared to that of radiologists. The comparison between model prediction and expert evaluation reveals the benefit of our approach over human judgement in predicting thyroid nodule malignancy. The results of the experiments show that the suggested algorithm performs better. Nodules of TI-RADS category 4 were used. The area under the receiver operating characteristic curve in the validation dataset was 0.92 (with accuracy of 0.70, sensitivity of 0.81 and specificity of 0.58).

  • Empirical wavelet decomposition of photoplethysmographic signal for hypertension risk stratification and detection of diabetes mellitus using machine learning techniques   Order a copy of this article
    by Muzaffar Khan, Bikesh Kumar Singh, Neelamshobha Nirala 
    Abstract: Hypertension (HT) is a leading risk factor for cardiovascular disease (CVD), and the overlap of diabetes mellitus (DM) with hypertension can lead to severe complications. Presently, the diagnostic method for detecting hypertension and DM is unsuitable for large-scale screening. The proposed model uses a statistical feature extracted by decomposing the PPG signal into a sub-band signal using Empirical wavelet transform (EWT), a comparative study conducted between various soft and hard computing classification models. The highest accuracy achieved by sequential neural network for the three categories, namely normal (NT) vs. prehypertension (PHT), NT vs. hypertension type 1 (HT-I), NT vs. hypertension type 2 (HT-II) in terms of F1 scores is 78.9%, 91.2% and 94%, respectively and F1 score of 97.9% for detection of DM-II patients. We conclude that soft computing techniques such as deep learning neural networks have shown superior performance compared to hard computing techniques. Furthermore, features selected using a hybrid feature selection technique were found to improve the classifier’s performance. The main advantage of the proposed model that uses a decomposition technique is found to be more immune to noisy PPG signals, overcoming the limitation of the morphological-based model.

    by P. Jenifer Darling Rosita, W. Stalin Jacob, R. Kalpana, T. Cynthia Anbuselvi 
    Abstract: The segmentation of medical images aids in managing the dose of medication, as well as the dosage of exposure to radiation, limiting the development of diseases like tumours, and monitoring the progression of diseases like cancer. The process of segmentation involves the division of a picture into distinct regions that each includes fragments of pixels that have similar characteristics. The regions should have a strong link to the items or elements of interest depicted in the picture in order to be expressive and useful for image analysis and interpretation. A proposal is made for an interactive framework that takes a deep learning approach. P-Net is the first stage of the framework, and it is used to produce an initial automated segmentation. The second stage is where the framework is implemented. This interaction is included in the input of the R-Net.

  • Detection of diabetic retinopathy severity from fundus images: DCNN   Order a copy of this article
    by T.Senthil Kumar, R. Muthalagu, L. Mohana Sundari, M. Nalini 
    Abstract: Diabetes retinopathy is a frequent diabetic complication that damages the retina and, if left untreated, may lead to blindness. The exponential rise in the number of diabetics throughout the globe has resulted in an equivalent rise in the number of diabetic retinopathy (DR) patients, one of the most serious consequences of diabetes. The goal of this research is to develop a hybrid solution approach for identifying diabetic retinopathy using retinal fundus pictures. The process of retinal vascular segmentation is critical for detecting a variety of eye disorders, such as the effects of diabetes on the eyes, also known as diabetic retinopathy. Morphologically based operations were used for the autoextraction of retinal blood vessels. Wavelet decomposition and back propagation neural networks were used to extract retinal vascular characteristics and evaluate the dataset that was used for this article. Morphologically based operations were also used for autoextraction of retinal blood vessels.

    by T. Senthil Kumar, Ashok Vajravelu, R. Muthalagu, P. Sri Latha 
    Abstract: On the basis of data obtained from brain imaging, a number of different machine learning (ML) methods may be used to categorise Alzheimer’s disease (AD). Convolutional neural networks have been suggested for the classification of Alzheimer’s disease based on anatomical MRI in more than 30 different studies. Since the frameworks and implementation details of many researchers aren’t available to the public, it makes them difficult to replicate. This article extracts the green channel initially, which is further enhanced by using super resolution algorithm. Convolutional neural network is applied to the contrast-enhanced image. We used CNN and T1-weighted MRI to broaden open-source solution for Alzheimer’s disease categorisation. Preprocessing, classification, and evaluation techniques for deep learning are included in the framework as well as tools for converting ADNI, AIBL, and OASIS data to the standard of the BIDS format. By combining deep learning with radionics, the accuracy of Alzheimer’s disease diagnosis is increased.

  • Robust liver segmentation using marker controlled watershed transform   Order a copy of this article
    by Mohammad Anwarul Siddique, Shailendra Kumar Singh, Moin Hasan 
    Abstract: The liver is the body’s largest organ, and it is largely responsible for metabolism and detoxification. In computer vision-based biomedical image analysis, liver segmentation is a critical step in detecting liver cancer. Due to the complicated structure of abdominal computed tomography (CT) images, noise, and textural differences across the image, liver segmentation is a key task that results in under-segmentation and over-segmentation. This paper uses a marker-based watershed transform to segment the liver in abdominal CT images. The double stage Gaussian filter with texture and contrast enhancement (DSGFTCE) is used to improve image quality at the pre-processing stage. The performance of the proposed segmentation is assessed using various performance evaluation metrics such as dice score (DS), volume overlapping error (VOE), Jacquard index (JI) and relative volume difference on LiTS dataset. The performance comparison with previous state of arts shows that proposed liver segmentation scheme provides better results (DS = 0.968, VOE = 0.089, JI = 0.9379, RVD = 0.09) compared with existing techniques.

    by D. Ruban Thomas, V. Vasanth, R. Kishore, B. Kishore Kumar 
    Abstract: Foetal development characteristics are used to determine the effects of various maternal traits and identify people who are more likely to have adverse outcomes. Foetal development features were measured during each trimester of pregnancy and were impacted by several mothers socio-demographic and lifestyle factors. Ultrasound measures of the foetus are crucial during pregnancy. The stability of foetal growth features can be assessed using tracking analyses throughout pregnancy. The length of the femur, the long bone in the thigh, is one of the markers used to monitor foetal growth and health. Previous research concentrated on birth outcomes compared to the foetal development, during pregnancy. In this work, the femur length is measured using LabVIEW. An ultrasound finding of short femur length may signal the need for additional testing to rule out illnesses. Femur length is one of the several factors for determining a babys health.

  • Implementing machine learning techniques to predict bipolar disorder   Order a copy of this article
    by Nisha Agnihotri, Sanjeev Kumar Prasad 
    Abstract: Bipolar disorder (BD) is a mental and psychiatric disorder which is characterised by alternate mode swings between mania and depression is very common these days. The classification, modelling and characterisation and diagnosis of these mental disorders are important in medical research. An unexpected and unexplored area in BD is to judge the non-verbal behaviour of person accurately. Therefore, this paper address the challenges of detecting BD state by machine learning (ML) techniques to test the non-verbal behaviours activities like various facial expressions, voice recordings and body gestures of mentally ill and controlled persons in a whole spectrum. ML techniques can potentially provide new horizons in diagnosing and treating in mental healthcare. Further, this paper aims to present commonly used algorithms such as decision trees (DT), support vector mechanism (SVM), logistics regression (LR), K-nearest neighbours (KNN), etc. and describe their properties and performances which could act as a guide to select appropriate models. The study shows that people with controlled state behaves significantly different as compared to BD patients in their interpersonal accuracy (IPA). This develops a new training program to improve better understanding and psychosocial functionality in their rehabilitation.

    Abstract: Neurological illnesses such as epilepsy are among the most frequent. Epileptic sufferers’ lives are greatly impacted by early warnings of impending seizures. Using electroencephalogram signals, this research aims to create an epileptic seizure prediction algorithm that can automatically identify an epileptic seizure. Early seizure prediction using EEG data is now possible thanks to the latest machine learning algorithms. An average AUC of 0.74 is achieved by the new technique, compared to 0.72 for the state-of-the-art approach, a 3.25-fold increase in computing time. In-depth knowledge of seizure detection, classification, and potential future research areas may be gained through this presentation’s cutting-edge methodologies and concepts. Predicting seizure activity might benefit from a modified atom search optimisation-based deep recurrent neural network. Numerous hidden layers are used by the deep recurrent neural network (DRNN) classifier to predict seizure activity.

    Abstract: Retinal diseases could be diagnosed by the variations in size, shape and texture of features in retinal images. Colour fundus images are widely used for the diagnosis of retinal diseases like diabetic retinopathy (DR), glaucoma, age-related macular degeneration (AMD), etc. Image processing enhances the input image, which segments and highlights regions of interest and quantify it. In this paper, we have segmented optic disc and blood vessels in colour fundus images using an algorithm coded in MATLAB. The input images and their corresponding ground truth images were obtained from public datasets available in Kaggle. The validation of the segmented images is done for parameters like accuracy, sensitivity, precision, F-measure, Mathews correlation coefficient, Dice coefficient, Jaccard index and specificity. The algorithm could effectively segment images, with an average accuracy of 99.74% in segmenting optic disc and 94.74% that of blood vessels.

    Abstract: Diabetic retinopathy (DR) is a condition that results in impaired vision and is triggered by diabetic. These alterations in the retinal vessels may be traced back to hyperglycemia. Microaneurysms (MAs) seem to be the initial disease symptoms of DR, and a prompt identification of microaneurysms may assist in the detection of DR in the preclinical phase. Optical coherence imaging system, often known as OCT, is a non-invasive imaging technology that offers a cross-sectional picture of the retinal. We construct new probability foundations for support vector machines (SVMs) using informational differences and the Fisher score. The findings that were achieved were as follows: the accuracy criterion had a score of 96.32%, the sensitivity criterion had a score of 97.34%, the specificity criterion had a score of 95.42%, and the precision criterion had a score of 95.27%.

    by Xiangdong An, Hui-chuan Chen, Monty Taylor 
    Abstract: The authors assess the relationships among psychological distress, socioeconomic status, and health behaviour factors. Data from the Canadian Community Health Survey (CCHS) dataset was analysed for this study using hierarchical regression and ANOVA. Results show that daily energy expenditure is positively related with psychological distress. The authors also find that daily fruit consumption, daily green salad consumption, and monthly frequency of leisure activities are negatively associated with psychological distress. Furthermore, the results indicate that people with personal incomes of less than $20,000 perceive significantly higher distress than people with higher incomes. Among five occupation groups, the sales and services group perceives significantly higher distress compared to the other four groups. The four other occupation groups as categorised by CCHS do not perceive significantly different distress levels.

    Abstract: Strokes remain the main cause of major impairment that lasts for lengthy period of time and ranks as the third greatest cause of mortality overall in United States. The ability to accurately anticipate a stroke is very useful for facilitating earlier intervention as well as treatments. Several studies have concentrated on determining the chance of a heart attack; on the other hand, only few have investigated the possibility of a brain attack. Various machine learning techniques are being created to estimate the chance of a cerebral infarction. We present a data-driven classifiers deep neural Networks (ResNet) for diagnosing strokes predicated on 12-leads ECG information. The quality of the model, which has been fine-tuned to perfection, allows us to achieve a training correctness of 99.99% and an accuracy rate of 85.82%. The findings imply that ECG is a viable adjunct tool for diagnosing stroke.

    by K. Kavin Kumar, S. Mythili, S. Prabhu Kumar 
    Abstract: The purpose of this study is to show about using OpenCV and deep learning techniques to design and implement a face recognition-based ATM security system. Face recognition only provides service to the user if the user is authentic or if the user has been validated by an authentic ATM card user. Users are authenticated by comparing the persons video taken in front of the ATM. The proposed method identifies the right persons by comparing the blink of eyes. If someone enter the ATM with photocopy of another person, checking the blink of eyes the validation is made. If the user is authentic, to strengthen the models accuracy, the current image is being utilised. A web link is sent to the registered mobile number that owns the ATM card, to verify the access of the illegitimate user to his/her account only then the user is considered as a legitimate user. Histogram algorithms and deep learning approaches are used by the system to identify persons. To process the image and detect the faces in the image, this system use the OpenCV package. Face recognition is achieved through the use of an open CV and deep learning.

The separation process has been analysed by using COMSOL Multiphysics software and found that the electrode with the minimum gap of 25 um acquired optimum results at an applied voltage of 8 V. The proposed device gave a high separation efficiency of 89.5% and a separation purity of 99.63%. The enhanced microfluidic device gave better results compared to other recent works and is exceptionally suitable for separation of micro-bio-particles.

  • Diffusion tensor imaging for Alzheimer’s disease classification using a bag of features and majority voting   Order a copy of this article

    Abstract: Alzheimer’s disease (AD) is a neurodegenerative disease and the most common cause of dementia. Thus, various neuroimaging-based methods were proposed to detect this disease at its early stage, called mild cognitive impairment (MCI). We developed a novel approach combining Diffusion tensor imaging (DTI)-indices and ensemble learning to classify AD. A bag of features (BoF) is used to retrieve the locale features, and a support vector machine (SVM) is applied for classification. The majority voting technique is used to combine the final predicted labels. The proposed method achieves an accuracy of 94.0%, 97.0%, and 95.9% to classify CN vs. MCI, CN vs. AD, and MCI vs. AD, respectively.
    Keywords: diffusion tensor imaging; Alzheimer’s disease; bag of features; BoF; support vector machine; SVM; majority voting.

  • An intelligent method for predicting cardiac disease based on PSO-convolutional neural network   Order a copy of this article
    by M. Balamurugan, P. Blessed Prince 
    Abstract: Cardiovascular disease (also known as CVD) is one of the primary contributors to both morbidity and death. The present state of the art in artificial intelligence plays a significant part in the process of aiding medical professionals in the diagnosis of a variety of disorders. A hybrid framework is proposed for the diagnosis of cardiovascular illnesses by analysing medical voice data. Eleven datasets comprising 14,416 numerical characteristics may be produced by using the method that has been suggested. From the datasets that are produced as a consequence, numerical and graphical characteristics are extracted. In the third layer, numerical data is provided to five separate machine learning (ML) techniques and graphical characteristics are transmitted to convolutional neural networks (CNNs), with transfer learning utilised to choose the best suited configurations. From a benchmark dataset, the PSO-CNN technique that was presented obtains an accuracy of 96.78%.
    Keywords: cardiovascular; PSO-CNN; optimisation; machine learning.
