Abstract COVID-19 has challenged health professionals in widely divergent areas, including innovation of practice, communication, multidisciplinary activities, broader use of technology, and adaptability. The role of the dietitian and other health professionals in dealing with the evolving crisis might be considered essential in treating patients. Given the limited access to various food options, nutrition screening and assessment deserves a high priority to complete a comprehensive nutrition evaluation, identify nutrition risks, prioritize care, and provide early nutrition intervention and support to all patients with or who have had, COVID-19 and are experiencing ongoing symptoms. Such an intervention would benefit the patients and the health system by reducing the length of hospital stay, ameliorating further complications, limiting hospital readmission, enhancing recovery, and assisting in the management of comorbidities and their metabolic alterations. This brief overview outlines the essential role of nutrition intervention and support as part of an integrated, multidisciplinary treatment program for the care of COVID-19 patients during the pandemic. Restrictive movements have changed consultative approaches, and the importance of Telenutrition for the effective communication of health status and recommendations.

Resumo A COVID-19 desafiou profissionais de saúde em diversas áreas, incluindo inovação da prática, comunicação, atividades multidisciplinares, uso amplo de tecnologia e adaptabilidade. O papel do nutricionista e de outros profissionais de saúde para lidar com a crise em expansão pode ser considerado essencial no tratamento de pacientes. Devido ao acesso limitado a várias opções de alimentos, a triagem e a avaliação nutricional devem ser priorizadas para a obtenção de uma avaliação nutricional abrangente, a fim de identificar riscos nutricionais, priorizar atendimento e possibilitar a intervenção nutricional precoce e o apoio a todos os pacientes com, ou que tiveram, COVID-19 e apresentem sintomas contínuos. Tal intervenção traria grande benefício aos pacientes e ao sistema de saúde, ao reduzir o tempo de internação, amenizar complicações posteriores, limitar a readmissão hospitalar, potencializar a recuperação e auxiliar no manejo das comorbidades e suas alterações metabólicas. Esta breve descrição elucida o papel essencial da intervenção nutricional e do apoio como parte de um programa de tratamento multidisciplinar para o cuidado de pacientes com COVID-19 durante a pandemia. Movimentos restritivos mudaram as abordagens consultivas e a importância da telenutrição para a comunicação eficaz do estado de saúde e das recomendações.

Abstract The COVID-19 pandemic has highlighted the economic, social, and oral care health inequities in societies, especially in the developing world. Severe restrictions have been imposed on dental practices, limiting prophylactic and routine oral care health, allowing treatment only for emergencies. Since dental care includes procedures that generate aerosols, the risk of infection for dental personnel has increased significantly. In this review, a comprehensive and updated source of information about SARS-CoV-2/COVID-19 and the impacts it is having on oral health care is presented. The ongoing repercussions in dental practice and in dental education, including the opportunities for practice innovation that are evolving, are also indicated. Also, a discussion of the psychosocial factors that affect health and the quality of life of an individual, such as stress, depression, and anxiety, is provided. This pandemic may be an opportunity to promote the inclusion of well-established prevention measures, together with the use of teledentistry in academic dental curricula, encourage the implementation of new perspectives for the effective instruction and interactions with students, and foster the transition toward e-learning strategies in dental education.

Resumo A pandemia COVID-19 destacou as desigualdades econômicas, sociais e de saúde bucal, especialmente no mundo em desenvolvimento. Severas restrições têm sido impostas para a prática odontológica, limitando a rotina de saúde bucal, permitindo o tratamento apenas em emergências. Como o atendimento odontológico inclui procedimentos que geram aerossóis, o risco de infecção para a equipe odontológica aumentou significativamente. Nesta revisão, é abordada uma fonte abrangente e atualizada de informações sobre o SARS-CoV-2/COVID-19 e os impactos que têm nos cuidados de saúde bucal. As repercussões contínuas na profissão odontológica e na educação odontológica, incluindo as oportunidades de inovação da prática. Além disso, é fornecido o efeito de fatores psicossociais que afetam a saúde e a qualidade de vida, como estresse, depressão e ansiedade. Esta pandemia pode ser uma oportunidade para promover a inclusão de medidas de prevenção bem estabelecidas, juntamente com o uso da teledontologia nos currículos acadêmicos de odontologia, trazendo novas perspectivas sobre a forma de ensinar e interagir com os alunos, com a transição para estratégias de e-learning na educação odontológica.

In view of anticancer activity of 7 β-acetoxywithanolide D (2) and 7β-16α-diacetoxywithonide D (3), isolated from the leaves of Acnistus arborescens (Solanaceae), five withanolide derivatives were obtained and their structures were determined by NMR, MS and IV data analysis. The in vitro anticancer activity of these derivatives was evaluated in a panel of cancer cell lines: human breast (BC-1), human lung (Lu1), human colon (Col2) and human oral epidermoid carcinoma (KB). Compounds 2a (acetylation of 2), 3b (oxidation of 3) and 2c (hydrogenation of 2) exhibited the highest anticancer activity against human lung cancer cells, with ED50 values of 0.19, 0.25 and 0.63 μg/mL, respectively.

Uma análise dos componentes da água-de-coco (Cocos nucifera L.) de duas variedades da fruta (verde e amarelo) por hidrodestilação e extração com solvente, mostrou a presença de álcoois, cetonas, tióis, ácidos carboxílicos, fenóis, e ésteres. Significativa atividade antioxidante foi observada, usando o método DPPH, para as amostras obtidas por hidrodestilação e extração de éter de petróleo para ambas as variedades do coco.

An analysis of the constituents of coconut (Cocos nucifera L.) water from two fruit varieties (green and yellow) by hydrodistillation and solvent extraction showed the presence of alcohols, ketones, thiols, carboxylic acids, phenols, and esters. Substantial antioxidant activity was observed, using the DPPH assay, for the samples obtained by hydrodistillation and petroleum ether extraction of both coconut varieties.

Each day, Earth's finite resources are being depleted for energy, for material goods, for transportation, for housing, and for drugs. As we evolve scientifically and technologically, and as the population of the world rapidly approaches 7 billion and beyond, among the many issues with which we are faced is the continued availability of drugs for future global health care. Medicinal agents are primarily derived from two sources, synthetic and natural, or in some cases, as semi-synthetic compounds, a mixture of the two. For the developed world, efforts have been initiated to make drug production "greener", with milder reagents, shorter reaction times, and more efficient processing, thereby using less energy, and reactions which are more atom efficient, and generate fewer by-products. However, most of the world's population uses plants, in either crude or extract form, for their primary health care. There is relatively little discussion as yet, about the long term effects of the current, non-sustainable harvesting methods for medicinal plants from the wild, which are depleting these critical resources without concurrent initiatives to commercialize their cultivation. To meet future public health care needs, a paradigm shift is required in order to adopt new approaches using contemporary technology which will result in drugs being regarded as a sustainable commodity, irrespective of their source. In this presentation, several approaches to enhancing and sustaining the availability of drugs, both synthetic and natural, will be discussed, including the use of vegetables as chemical reagents, and the deployment of integrated strategies involving information systems, biotechnology, nanotechnology, and detection techniques for the development of medicinal plants with enhanced levels of bioactive agents.

Um novo alcalóide denominado Helindicina (1), e o conhecido licopsamina (2) foram isolados das raízes de Heliotropium indicum (Boraginaceae). As estruturas foram estabelecidas tendo como base um amplo estudo de 1D e 2D RMN (COSY, HMBC, HMQC, NOESY) e HREIMS. Este representa o primeiro relato de um alcalóide contendo um anel lacônico no gênero Heliotropium. Estes alcalóides mostraram moderada atividade antioxidante.

Helindicine (1), a new pyrrolizidine alkaloid with unusual structural features, together with the known lycopsamine (2), were isolated from the roots of Heliotropium indicum (Boraginaceae). The structures were established by a combination of 1D and 2D NMR methods (COSY, HMQC, HMBC, and NOESY) and HREIMS. This is the first report of a lactone pyrrolizidine alkaloid in the genus Heliotropium. Compounds 1 and 2 were assayed for antioxidant activity and showed moderate activity.
