ABSTRACT
In this era of cutting-edge research and digitalization, artificial intelligence (AI) has rapidly penetrated all subspecialties, including ophthalmology. Managing AI data and analytics is cumbersome, and implementing blockchain technology has made this task less challenging. Blockchain technology is an advanced mechanism with a robust database that allows the unambiguous sharing of widespread information within a business model or network. The data is stored in blocks that are linked together in chains. Since its inception in 2008, blockchain technology has grown over the years, and its novel use in ophthalmology has been less well documented. This section on current ophthalmology discusses the novel use and future of blockchain technology for intraocular lens power calculation and refractive surgery workup, ophthalmic genetics, payment methods, international data documentation, retinal images, global myopia pandemic, virtual pharmacy, and drug compliance and treatment. The authors have also provided valuable insights into various terminologies and definitions used in blockchain technology.

ABSTRACT
Big data has been a game changer of machine learning. But, big data is a form of centralized version of data only available and accessible to the technology giants. A way to decentralize this data and make machine learning accessible to the smaller organizations is via the blockchain technology. This peer?to?peer network creates a common database accessible to those in the network. Furthermore, blockchain helps in securing the digital data and prevents data tampering due to human interactions. This technology keeps a constant track of the document in terms of creation, editing, etc., and makes this information accessible to all. It is a chain of data being distributed across many computers, with a database containing details about each transaction. This record helps in data security and prevents data modification. This technology also helps create big data from multiple sources of small data paving way for creating a well serving artificial intelligence model. Here in this manuscript, we discuss about the usage of blockchain, its current role in machine learning and challenges faced by it

ABSTRACT
In recent years, China has been vigorously promoting the construction of medical informatization, with ever improving share and interoperability model of medical and health care big data centering on electronic health records. Current problems in the management and utilization of electronic health records were found in such aspects as hidden risk exposure in the centralized data storage, poor access in data sharing, and poor distribution of rights and interests. These problems can be tackled effectively by the distributed storage, efficient secret data sharing, on-demand collaborative intelligent computing and other features of blockchain technology. The blockchain technology is still immature to use in medical archiving, and large-scale application of electronic health archives blockchain faces challengs in technology, governance and operation. The authors suggest to enhance scientific research on blockchain technology, improve the construction of blockchain application enabling system, and to launch the pilot project of health archives blockchain.

Background: Currently, the South African public healthcare system is hampered by a lack of effective patient data management. This leads to, amongst other challenges, a lack of transparency in the management of patients' health information and unsecure medical records. Blockchain, on the other hand, can make healthcare records more secure, easily auditable, and hence more reliable. These advantages, among others, make Blockchain an appealing technology for managing patients' health information in the South African context. Objectives: The study investigated the antecedents of the adoption of blockchain technology as a tool to improve the management of patients' health information in the South African public healthcare sector. Method: The four pillars of a health information system (strong leadership, contingency plan, security and privacy, and IT or vendor support) were adopted as the theoretical grounding for the study. Qualitative data were collected through interviews with IT specialists and healthcare professionals working in the public healthcare sector. Results: The study identified 11 antecedents that can be related to the four pillars of a health information system. These antecedents must be addressed for blockchain to contribute meaningfully to enhancing patients' health information management in South Africa. Conclusion: Although blockchain can contribute meaningfully to addressing health information management challenges in South Africa, contextual factors need to be considered for it to fulfil its promises. It is anticipated that the study findings will help stakeholders in the South African public healthcare sector to make informed decisions in their quest to deploy technology innovations like blockchain.
ABSTRACT
Background: With the rise of noncommunicable diseases (NCDs) in sub-Saharan Africa (SSA), the concept of digital self-management presents great opportunities for relieving some of the burdens healthcare systems face. However, for this to be realised, effective use of digital health in self-management and assessment is essential. Objective: The objective of this scoping review was to identify social determinants and cognitive factors with potential influence on digital health use in self-management of chronic medical conditions associated with NCDs in SSA. Method: The 5-stage scoping review framework was used to search, identify, and filter publications over a 10-year period from two major databases, Google Scholar and Pubmed. Based on the inclusion criteria, a total of 12 documents were chosen for analysis. Results: Findings reveal that social determinants such as cultural values and societal practices demand a rethinking of how digital health for self-management of chronic diseases are designed and developed for use in SSA, whereas a cognitive factor such as self-efficacy is central in digital health use in self-management of chronic conditions, particularly in areas like adherence to medication, diet and exercise programmes. Conclusion: Owing to the unique characteristics of digital health users in SSA, technologies and content (particularly those for self-management of chronic diseases) should be tailored to the diverse needs of the population. It is through this that the region can fully benefit from the potential of digital health use in self-management of chronic diseases associated with NCDs.

Objetivo: O Sistema Único de Saúde (SUS) vem investido nas tecnologias da internet das coisas Internet of Things (IoT), em inglês para coletar dados dos pacientes. Esse artigo aponta as fragilidades quanto à privacidade de usuários do SUS e propor uma solução teórica, ainda a ser testada a partir de uma infraestrutura pautada em armazenamento pessoal de dados personal data stores (PDS), em inglês ou, a partir da segurança da blockchain. Metodologia: realizou-se revisão narrativa da literatura nacional e internacional relacionados a instrumentos, políticas e casos voltados a tecnologias de informação e comunicação na saúde a fim de apontar as fragilidades quanto à privacidade de usuários desse sistema. Resultados: percebeu-se que ainda existe uma falta de transparência no tratamento dos dados pessoais e pouco accountability por parte dos cidadãos, se fazendo necessária uma mudança de estratégia tecnológica e de governança. Conclusão: o PDS, de fato, empodera o usuário na medida que dá maior controle e transparência sobre o tratamento de seus dados. No entanto, essa solução, em um sistema como o utilizado pelo Departamento de Informática do SUS, pode comprometer a precisão dos dados usados nas políticas públicas, ao mesmo tempo que pode comprometer alguns direitos dos cidadãos, pois são dados salvos em registros e os metadados estão disponíveis publicamente. A implementação do PDS ainda não possui perspectiva de resultado ótimo. Ainda existem algumas restrições metodológicas quanto aos direitos dos cidadãos ou à eficiência do Estado, mas é um passo no empoderamento civil e uma melhoria exigida por lei quanto à privacidade e à proteção de dados pessoais.
Objective: Brazilian Unified Health System (SUS, in Portuguese) has invested in Internet of Things (IoT) technologies to collect data from patients. This article aims to point out the weaknesses regarding the privacy of users of the SUS and to propose a theoretical solution, yet to be evaluated, and based on a Personal Data Storages (PDS) infrastructure or on blockchain security. Methods: aA narrative review of national and international literature related to instruments, policies, and cases related to information and communication technologies in health was conducted to point out the weaknesses regarding the privacy of users of this system. Results: there is still a lack of transparency in the treatment of personal data and little accountability on the part of citizens, making it necessary to change the technological and governance strategy. Conclusion: PDS empowers users as it gives greater control and transparency over the treatment of data. However, this solution, in a system like the one used by their Computer Department, can compromise the accuracy of the data used in public policies, while it can compromise some citizens' rights, as this data is saved in records and the metadata is publicly available. The implementation of a solution like this does not yet have the prospect of an optimal result, without any methodological restriction on citizens' rights or the efficiency of the State, but it is a step in civil empowerment and an improvement required by law concerning privacy and protection of personal data. The implementation of the PDS does not yet have the prospect of an optimal result. There are still methodological restrictions regarding the rights of citizens or the efficiency of the State. But it is a step in civil empowerment and an improvement required by law in terms of privacy and the protection of personal data.

Metodología: se realizó una revisión narrativa de la literatura nacional e internacional relacionada con instrumentos, políticas y casos relacionados con las tecnologías de la información y la comunicación en salud con el fin de señalar las debilidades en cuanto a la privacidad de los usuarios de este sistema. Resultados: se notó, entonces, que aún existe falta de transparencia en el tratamiento de estos datos personales y poca rendición de cuentas por parte de la ciudadanía, por lo que es necesario cambiar la estrategia tecnológica y de gobernanza. Conclusión: se concluye que PDS, de hecho, empodera a los usuarios ya que brinda un mayor control y transparencia sobre el tratamiento de sus datos. Sin embargo, esta solución, en un sistema como el utilizado por el Departamento de Computación del SUS, puede comprometer la precisión de los datos utilizados en las políticas públicas, al mismo tiempo que puede comprometer algunos derechos civiles, ya que estos datos se guardan en registros y metadatos están disponibles públicamente. La implementación de una solución como esta todavía no tiene la perspectiva de un resultado óptimo, sin ninguna restricción metodológica sobre los derechos de los ciudadanos o la eficiencia del Estado, pero es un paso en el empoderamiento civil y una mejora requerida por la ley con respecto a la privacidad y protección de datos personales.
