RESUMO
ABSTRACT Introduction: Since the coronavirus disease 2019 (COVID-19) pandemic, cardiac surgeries in patients with previous infection by COVID-19 were suspended or postponed, which led to surgeries performed in patients with an advanced stage of their disease and an increase in the waiting list. There is a heterogeneous attitude in Latin America on the optimal timing to cardiac surgery in patients with previous COVID-19 infection due to scarce data on its outcome. Two Latin American associations joined to establish common suggestions on the optimal timing of surgery in patients with previous COVID-19 infection. Methods: Data collection was performed using a pre-established form, which included year of publication, objective, type of study (prospective/retrospective, descriptive/analytical), number of patients, year of study, waiting time between infection and surgery, type of surgery, morbidity, mortality, and conclusions regarding the association between mortality and morbidity. Final recommendations were approved by the board of directors of Latin American Association of Cardiac and Endovascular Surgery (LACES) and Latin American Confederation of Anesthesia Societies (CLASA). Results: Of the initial 1,016 articles, 11 comprised the final selection. Only six of them included patients who underwent cardiac surgery. According to the analyzed literature, optimal timing for cardiac surgery needs to consider the following aspects: deferable surgery, symptomatic COVID-19 infection, completeness of COVID-19 vaccination. Conclusion: These recommendations derive from the analysis of the scarce literature published at present on outcomes after cardiac surgery in patients with previous COVID-19 infection. These are to be taken as a dynamic recommendation in which Latin American reality was taken into consideration.
RESUMO
Background: amelogenesis imperfecta (AI) is a group of disorders that affect the enamel of the teeth, either in quality or quantity. this alteration causes sensitivity and is associated with factors that could affect the strength of the adhesive bond of the restorative material. aim: to review the literature regarding the most used temporary restorative treatment in children and adolescents with AI. methods: this scoping review aimed to include case reports, literature reviews and original studies that evaluated restorative materials for the teeth of children and adolescents with AI. editorials, meeting abstracts and letters to the editor were excluded. the following electronic databases were used: Medline (Ovid), PubMed, Ebsco, Scopus (Elsevier) and Web of Science (Thomson Reuters). manual searches in the reference lists of the included articles were also carried out. finally, a search in Google Scholar restricted to the first 100 hits was performed. duplicates were eliminated upon identification. the search covered a period between the years of 2011 and 2016. PRISMA guidelines were used for reporting the review. the evidence ranking was carried out by means of the Oxford criteria. results: six articles met the eligibility criteria and were included in this scoping review. three articles were case reports, one was a review and two were original studies. tor the treatment of AI, direct or indirect composite resins were the most commonly used material of choice in the retrieved studies because they demonstrate greater longevity, aesthetics and function compared to the other materials used. conclusions: among children and adolescents with AI, the temporary restorative treatment that demonstrated better long-term results in permanent teeth was the direct and indirect composite resins. however, high quality studies should be conducted to confirm the results presented herein.
