ABSTRACT
The aftereffect and consequences of COVID-19 are multiple and include dissimilar aspects, with a great negative impact on health systems and humanity. In this sense, having updated and relevant information favors the arduous confrontation with this pandemic. The purpose of this research is updating knowledge about the oral manifestations of COVID-19 infection. A bibliographical review was carried out. The search was carried out through Google Scholar, SciELO and other information sources from the Cuba Virtual Health Library. The impact of COVID-19 on oral health is determined by the patient's immune system, the pharmacotherapy they receive, and the pathogenesis of the virus. Symptoms of dry mouth, hypogeusia, dysgeusia, and ageusia predominate, even before respiratory symptoms. Other manifestations include oropharyngeal candidiasis;appear approximately in 5% of patients, days after diagnosis. The main oral manifestations related to COVID-19 reported in the literature are: hyposalivation, xerostomia, ageusia, hypogeusia, dysgeusia, herpetic lesions, and candidiasis.
ABSTRACT
Supply Chain Management (SCM) has grown in the last years due to the changing and evolutionary environment. The SCM has become fundamental for gaining financial and social, among others, benefits. Currently, the traditional SCM mechanisms have some areas of improvement, such as the transparency and lack of information, long waiting times for information retrieval and data fidelity. The past months our daily lives have been changing in a drastic way due to COVID-19 and some industries were affected but with this change there has been some opportunities to improve. In this article we describe the main concepts about the blockchain technology, the smart contracts, and their main use. We talk about different areas that these technologies could help to improve in different ways of their internal and external processes. Our main discussion is the description and improvement in the performance inside a supply chain, how it could be possible to speed up the information sharing, how a smart contract could be applied to a consumer-supplier relationship in the healthcare supply chain and the benefits that it would bring to it due to the quick times that this area demands because of the nature of their transactions and operations that are critical to maintain the needs of the industry. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
