Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss among the elderly, affecting approximately 196 million people globally. Traditional diagnostic methods for AMD, which rely on human grading of fundus images, are hindered by inefficiencies and subjectivity. The DeepDrAMD model, a hierarchical vision transformer-based deep learning system, addresses these limitations by providing a more accurate, rapid, and automated diagnosis of AMD using color fundus images. Beyond diagnostics, understanding the complex molecular mechanisms of AMD pathogenesis, such as protein clearance, inflammasome activation, and calcium channel dynamics in the retinal pigment epithelium (RPE), is crucial for developing targeted therapies. Neovascular AMD (nAMD) presents additional challenges due to aberrant blood vessel proliferation, with recent studies highlighting the role of proteins like thrombospondin-1 and the enzyme granzyme B in choroidal neovascularization.

The progression of fibrosis in nAMD and the need for reliable biomarkers to detect this condition underscores the importance of refining imaging techniques and consensus definitions. Systemic health factors such as hypertension, cardiovascular disease, and genetic variants further influence AMD risk, necessitating comprehensive studies to elucidate these relationships. Investigations into the roles of retinal carotenoids, flavonoids, and anti-inflammatory agents, as well as advancements in drug delivery systems and ultrahigh resolution OCT imaging, offer promising avenues for improving AMD management and treatment outcomes. The introduction of ultrahigh-resolution spectral domain-OCT (UHR SD-OCT) and machine learning-based analysis of imaging data enables more precise quantification of sub-retinal pigment epithelium (RPE) deposits, facilitating early detection and monitoring of AMD progression. Additionally, novel drug delivery systems, including implants and non-stimuli responsive hydrogels, enhance the efficacy of treatments by providing controlled and sustained release of therapeutic agents.

Collectively, these multidisciplinary efforts aim to enhance early detection, understand disease progression, and develop effective therapeutic interventions for AMD, leveraging state-of-the-art technologies and comprehensive molecular insights.

However, the success of deep learning models often relies on vast amounts of labeled data, which are not always readily available in medical imaging due to privacy concerns and the laborintensive nature of annotation. This limitation has spurred the need for more efficient and scalable solutions to harness the power of deep learning for medical image analysis. Transfer learning, a subfield of machine learning, has emerged as a promising approach to overcome these data scarcity challenges. In the context of medical image analysis, transfer learning involves leveraging knowledge learned from one domain (e.g., natural images) and applying it to a different but related domain (e.g., medical images). This comprehensive survey paper delves into the significance of transfer learning in the context of medical image analysis, aiming to provide insights into its key findings and contributions. The core objective of this survey is to address the limitations of traditional “in-house” deep learning models that are trained and tested on the same dataset. Within this survey, we dissect these challenges and present a thorough examination of existing transfer learning approaches for medical image analysis. We explore the strategies that have been devised to fine-tune, adapt, and transfer knowledge across domains. Furthermore, we showcase comparative analyses of these transfer learning approaches, highlighting their strengths, weaknesses, and areas of applicability. The insights provided herein are poised to shape the future of computer-aided disease diagnosis systems and advance the field of transfer learningbased medical image analysis.

The paper aims to develop a more accurate cervical cancer (CC) detection method. As a consequence of this, the data's dependability will increase. As a direct result, gathering new biomedical data has emerged as a primary goal. The three most significant high-dimensional biological data analytics that may be conducted using bioinformatics are sample classification, early disease detection, and disease diagnosis. This paper provides an earlier data-feature selection technique based on stability (EDFSS). In addition, we construct a two-stage heterogeneous stacked ensemble learning model (HSELM) for predicting cervical cancer patient survival. Both models are designed to predict whether a patient will survive their disease. EDFSS discovers feature subsets from large cancer datasets that are particularly valuable for developing other models. The usage of this strategy is predicted to result in enhanced classification accuracy. The CC Risk Factors, 32 independent risk factors, and four dependent variables were used in this study. This also made extensive use of the CC Risk Factors. These strategies were presented to sanitize the risk variables contained in the previous algorithm. This was done to improve the algorithm's efficacy. The MLP classifier exhibited the best overall classification performance, with 97.51% accuracy, 96.23% precision, 98.10% recall, and 95.21% F1-measure. The paper found that risk variables were selected to train several ML classifiers to predict cervical cancer.

The identification of human activities holds paramount importance in diverse domains, including CCTV monitoring and human-robot interaction. While existing Human Activity Recognition (HAR) techniques have made substantial progress, challenges persist due to their reliance on manual feature extraction. This research introduces an innovative approach to analyze and identify human actions within small video sequences, employing a convolutional neural network (CNN). The suggested CNN approach combines a 3D convolution technique with a convolutional Long Short-Term Memory process, enabling concurrent examination of spatiotemporal data spanning multiple video frames. In contrast to conventional frame-byframe analysis, this CNN detects and measures distinctions and resemblances among objects in consecutive frames, enhancing the capability for more intuitive identifications. This approach maximizes processing resources, ensuring efficient training and classification, thereby yielding precise results rapidly. Our novel approach addresses the challenge of model generalization by overcoming the limitations associated with manual feature extraction. By leveraging the combined power of 3D convolution and LSTM, our CNN model demonstrates enhanced capabilities in recognizing and understanding human actions within dynamic video sequences. The presented methodology not only contributes to the advancement of HAR techniques but also opens avenues for more effective utilization of processing resources in real-world applications.

The healthcare industry is one area where blockchain technology is being used to ensure security and reliability. Blockchain is like a big list where each new transaction is added to the end of the list, and each transaction is connected to the one before it. This creates a secure and unchangeable record of all transactions. To ensure everyone agrees on the new transactions being added, blockchain uses methods that involve everyone checking each other's work. Patient information is very sensitive, so it is essential to keep it safe. In the past, each hospital stored patient information separately, making sharing information difficult and risky. By using blockchain, it can share information more easily without worrying about being changed or stolen. This research aims to combine blockchain and healthcare to make sharing information more secure and efficient.

The administration of organs and tissues is tedious and may lead to blackmarketing activity, particularly given high demand and low supply. This mishandling and mismanagement of organs may be alleviated by using technological advancements. Employment of technological advancements in organ donation leads to enhanced security and a significant reduction in intermediaries in organ acquisition. Thus, it enables the achievement of greater openness amongst donors and procurers. However, structures that keep all their data in a centralized database are more vulnerable to manipulation and illegal access. These risks of manipulation and illicit access may be compacted if the system is distributive in structure or sustains a distributive ledger/database, i.e., each network maintains a replica of the record. For the same, blockchain technology may significantly contribute to organ donation to overcome the associated challenges and constraints and meet the required levels of dependability. The current manuscript outlines OrDo (organ donation), a blockchain-based organ donation system that creates a transparent platform between organ donors and receivers. Furthermore, the proposed system uses Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) to maintain a layer of trust. To explain the possession requirement, DIDs, and VCs are used to provide a distinct identity and credentials. A trustworthy consensus algorithm is also used to establish a connection between the patient and the donor to achieve encrypted, consistent, reliable, and justified communication, which can be employed in various real-world scenarios.

Ensuring timely detection and precise categorization of brain tumors plays a vital role in the effective diagnosis and management of neuro-oncological conditions. Traditional manual approaches to brain tumor segmentation in imaging are frequently labor-intensive and prone to subjectivity, underscoring the need for a transition to automated methodologies. This research introduces a sophisticated deep learning architecture aimed at improving the accuracy and speed of brain tumor analysis. There are combinations of several classification algorithms, like binary classification (CNN algorithm, VGG19 algorithm) and multi-class classification (EfficientNetB0 algorithm). VGG19, with its 19 layers containing 16 convolution layers, 3 fully connected layers, and several max-pooling layers, achieves an accuracy of 86%. For multiclass classification, differentiating among various types of brain tumors, EfficientNetB0 is used. This model employs a compound scaling method to balance network depth, width, and resolution, resulting in higher accuracy and efficiency. The images are labelled using one-hot encoding: 0 for ‘Glioma Tumor’, 1 for ‘No Tumor’, 2 for ‘Meningioma Tumor, and 3 for ‘Pituitary Tumor’. EfficientNetB0 outperforms VGG19, achieving an accuracy of 97%, and demonstrates higher efficiency in computational power usage. Finally, we developed a user-friendly interface allowing users to upload MRI images and predict the presence and type of brain tumor using the trained models. This integration of advanced segmentation and classification techniques highlights the potential for improved performance in automated brain tumor diagnostics.
