ABSTRACT Objective: To analyze literature data about unnecessary exposure of pediatric emergency patients to ionizing agents from imaging examinations, nowadays and during times of COVID-19. Data sources: Between April and July 2020, articles were selected using the databases: Virtual Health Library, PubMed and Scientific Electronic Library Online. The following descriptors were used: [(pediatrics) AND (emergencies) AND (diagnostic imaging) AND (medical overuse)] and [(Coronavirus infections) OR (COVID-19) AND (pediatrics) AND (emergencies) AND (diagnostic imaging)]. Inclusion criteria were articles available in full, in Portuguese or English, published from 2016 to 2020 or from 2019 to 2020, and articles that covered the theme. Articles without adherence to the theme and duplicate texts in the databases were excluded. Data synthesis: 61 publications were identified, of which 17 were comprised in this review. Some imaging tests used in pediatric emergency departments increase the possibility of developing future malignancies in patients, since they emit ionizing radiation. There are clinical decision instruments that allow reducing unnecessary exam requests, avoiding over-medicalization, and hospital expenses. Moreover, with the COVID-19 pandemic, there was a growing concern about the overuse of imaging exams in the pediatric population, which highlights the problems pointed out by this review. Conclusions: It is necessary to improve hospital staff training, use clinical decision instruments and develop guidelines to reduce the number of exams required, allowing hospital cost savings; and reducing children's exposure to ionizing agents.

RESUMO Objetivo: Analisar dados da literatura sobre exposição desnecessária de pacientes da emergência pediátrica a agentes ionizantes dos exames de imagem, na atualidade e em tempos de COVID-19. Fontes de dados: Entre abril e julho de 2020 ocorreu a seleção dos artigos, utilizando-se as bases de dados: Biblioteca Virtual em Saúde, PubMed e Scientific Electronic Library Online. Utilizaram-se os descritores: [(pediatrics) AND (emergencies) AND (diagnostic imaging) AND (medical overuse)] e [(Coronavirus infections) OR (COVID-19) AND (pediatrics) AND (emergencies) AND (diagnostic imaging)]. Incluíram-se artigos disponíveis na íntegra, em português ou inglês, publicados no período de 2016 a 2020 ou de 2019 a 2020, e artigos que contemplassem o tema. Excluiu-se artigos sem aderência com a temática e textos duplicados. Síntese dos dados: Identificaram-se 61 publicações, sendo 17 utilizadas para a elaboração desta revisão. Alguns exames de imagem utilizados nos Setores de Urgência e Emergência (SUEs) pediátricos, por emitirem radiação ionizante, aumentam a possibilidade de desenvolver malignidades futuras nas crianças. Destarte, há instrumentos de decisão clínica que possibilitam diminuir requisições de exames desnecessários, evitando a sobremedicalização e os gastos hospitalares. Ademais, com a pandemia da COVID-19, cresceu a preocupação com o uso excessivo de exames de imagem na população pediátrica, o que reafirma a problematização deste estudo. Conclusões: Veem-se como necessárias a capacitação da equipe hospitalar, a utilização de instrumentos de decisão clínica e a confecção de protocolos que possam avaliar a singularidade da criança. Isso permitirá reduzir o número de exames requeridos, possibilitando economia de custos hospitalares e redução da exposição de crianças a agentes ionizantes.

Bioactive plant-derived molecules have emerged as therapeutic alternatives in the fight against the COVID-19 pandemic. In this investigation, principal bioactive compounds of the herbal infusion "horchata" from Ecuador were studied as potential novel inhibitors of the SARS-CoV-2 virus. The chemical composition of horchata was determined through a HPLC-DAD/ESI-MSn and GC-MS analysis while the inhibitory potential of the compounds on SARS-CoV-2 was determined by a computational prediction using various strategies, such as molecular docking and molecular dynamics simulations. Up to 51 different compounds were identified. The computational analysis of predicted targets reveals the compounds' possible anti-inflammatory (no steroidal) and antioxidant effects. Three compounds were identified as candidates for Mpro inhibition: benzoic acid, 2-(ethylthio)-ethyl ester, l-Leucine-N-isobutoxycarbonyl-N-methyl-heptyl and isorhamnetin and for PLpro: isorhamnetin-3-O-(6-Orhamnosyl-galactoside), dihydroxy-methoxyflavanone and dihydroxyphenyl)-5-hydroxy-4-oxochromen-7-yl]oxy-3,4,5-trihydroxyoxane-2-carboxylic acid. Our results suggest the potential of Ecuadorian horchata infusion as a starting scaffold for the development of new inhibitors of the SARS-CoV-2 Mpro and PLpro enzymes.

Background: Laboratory parameter abnormalities are commonly observed in COVID-19 patients; however, their clinical significance remains controversial. We assessed the prevalence, characteristics, and clinical impact of laboratory parameters in COVID-19 patients hospitalized in Daegu, Korea. Methods: We investigated the clinical and laboratory parameters of 1,952 COVID-19 patients on admission in nine hospitals in Daegu, Korea. The average patient age was 58.1 years, and 700 (35.9%) patients were men. The patients were classified into mild (N=1,612), moderate (N=294), and severe (N=46) disease groups based on clinical severity scores. We used chi-square test, multiple comparison analysis, and multinomial logistic regression to evaluate the correlation between laboratory parameters and disease severity. Results: Laboratory parameters on admission in the three disease groups were significantly different in terms of hematologic (Hb, Hct, white blood cell count, lymphocyte%, and platelet count), coagulation (prothrombin time and activated partial thromboplastin time), biochemical (albumin, aspartate aminotransferase, alanine aminotransferase, lactate, blood urea nitrogen, creatinine, and electrolytes), inflammatory (C-reactive protein and procalcitonin), cardiac (creatinine kinase MB isoenzyme and troponin I), and molecular virologic (Ct value of SARS-CoV-2 RdRP gene) parameters. Relative lymphopenia, prothrombin time prolongation, and hypoalbuminemia were significant indicators of COVID-19 severity. Patients with both hypoalbuminemia and lymphopenia had a higher risk of severe COVID-19. Conclusions: Laboratory parameter abnormalities on admission are common, are significantly associated with clinical severity, and can serve as independent predictors of COVID-19 severity. Monitoring the laboratory parameters, including albumin and lymphocyte count, is crucial for timely treatment of COVID-19.

Background: Seroprevalence studies of coronavirus disease 2019 (COVID-19) cases, including asymptomatic and past infections, are important to estimate the scale of the disease outbreak and to establish quarantine measures. We evaluated the clinical performance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody assays available in Korea for use in seroprevalence studies. Methods: The sensitivity, specificity, cross-reactivity, and interference of five SARS-CoV-2 antibody assays were evaluated using the following: 398 serum samples from confirmed COVID-19 patients, 510 negative control samples from before 2018 (pre-pandemic), 163 serum samples from patients with SARS, Middle East respiratory syndrome (MERS), and other viral infections, and five samples for the interference study. Results: The sensitivities of the five assays ranged from 92.2% to 98%, and their specificities, including cross-reactivity and interference, ranged from 97.5% to 100%. The agreement rates were excellent (kappa >0.9). Adjustment of the cutoff values could be considered through ROC curve analysis. The positive predictive values of the individual assays varied from 3.5% to 100% at a 0.1% prevalence but were as high as ≥95% when two assays were combined. Conclusions: The prevalence of COVID-19 in Korea is considered to be exceptionally low at present; thus, we recommend using a combination of two or more SARS-CoV-2 antibody assays rather than a single assay. These results could help select SARS-CoV-2 antibody assays for COVID-19 seroprevalence studies in Korea.

The sensitivity of molecular diagnostics could be affected by nucleotide variants in pathogen genes, and the sites affected by such variants should be monitored. We report a single-nucleotide variant (SNV) in the nucleocapsid (N) gene of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), i.e., G29179T, which impairs the diagnostic sensitivity of the Xpert Xpress SARS-CoV-2 assay (Cepheid, Sunnyvale, CA, USA). We observed significant differences between the threshold cycle (Ct) values for envelope (E) and N genes and confirmed the SNV as the cause of the differences using Sanger sequencing. This SNV, G29179T, is the most prevalent in Korea and is associated with the B.1.497 virus lineage, which is dominant in Korea. Clinical laboratories should be aware of the various SNVs in the SARS-CoV-2 genome and consider their potential effects on the diagnosis of coronavirus disease 2019.

Standard tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detect the presence of viral RNA using real-time reverse transcription (rRT)-PCR. Recently, convenient, rapid, and relatively inexpensive SARS-CoV-2 antigen (Ag) detection methods have been developed. The STANDARD Q COVID-19 Ag test (SD Biosensor, Inc., Suwon, Korea) is a rapid immunochromatography test that qualitatively detects the nucleocapsid protein of SARS-CoV-2 using gold conjugated antibodies. We evaluated its performance in comparison with that of Allplex 2019-nCoV Assay (Seegene, Seoul, Korea) in a retrospective case-control study using residual samples. The sensitivity and specificity of the STANDARD Q COVID-19 Ag test were 89.2% (58/65) and 96.0% (96/100), respectively. Cycle threshold (Ct) values for the three target SARS-CoV-2 genes (envelope, RNA-dependent RNA polymerase, and nucleocapsid genes) included in Allplex 2019-nCoV Assay were significantly lower in Ag test-positive patients than in Ag test-negative patients (P<0.001). The Ag test sensitivity was higher in samples with Ct≤30 and those collected one to five days post symptom onset. In conclusion, the STANDARD Q COVID-19 Ag test can serve as an alternative in high-prevalence settings, when the low sensitivity is compensated or when rRT-PCR tests are limited.

Aim To investigate clinical presentation of COVID-19 infection in pregnancy, its course during pregnancy, effects on pregnancy outcomes for both mothers and newborns as well as the potential for vertical transmission. Methods This retrospective observational study included all identifi ed COVID-19-positive pregnant women admitted to the Cantonal Hospital in Zenica at any stage of pregnancy or labour from 30 April 2020 to April 30 2021. Maternity and newborns were followed until discharge from the hospital. Results Twenty-four pregnant women were positive for COVID-19. There were 79.2% asymptomatic cases, 12.5% had mild symptoms, while 8.3% had more severe forms of the disease. The main follow-up morbidities were high BMI 33.3%, anaemia 16.7%, thrombocytopenia 12.5%, hypertensive disorders 4.2% and diabetes 4.2%. The rate of premature births was 33.3%, while 8.3% pregnant women had premature rupture of the amniotic sac. Caesarean section was done for 75% women while 25% delivered vaginally. Previous caesarean section (54.2%) was the most common indication for operative completion of labour. Twentythree (92%) live babies were born, of which 8 (33.3%) were admitted to the neonatal intensive care unit. Two (8%) intrauterine foetal deaths were recorded that occurred before admission to our hospital. Two infants (8.7%) had a positive PCR test for COVID-19. Conclusion COVID-19 viral disease in pregnancy is usually presented as an asymptomatic or mild disease. It is associated with high rates of preterm birth, admission of newborns to the intensive care unit and intrauterine foetal death. Vertical transmission is possible but the newborns were asymptomatic.

Abstract Cladocerans are a diverse group of species that show rapid responses to changes in environmental conditions. This adaptive capacity has important implications for egg production and life cycle, especially in transitory environments such as temporary waterbodies. The present study investigated the life history and egg production of Alona gutatta Sars, 1862 (Crustacea, Cladocera), an abundant and frequent species from a high-altitude temporary pond (Lagoa Seca, Minas Gerais, Brazil). Newly hatched neonates were monitored in relation to time of maturation, number of eggs produced per female and time of survival. Neonates required a mean of 8 days to mature. A. guttata survived for a mean of 30.9 ± 8.1 days and produced 2 eggs per brood, generating a mean of 10.95 ± 6.41 neonates during the entire life cycle. The rapid development, short time to produce eggs and long life cycle are important adaptations to the adverse environmental conditions of temporary aquatic environments, which can contribute to the rapid colonization of Alona guttata in transitory ecosystems.

Resumo Os cladóceros formam um grupo diverso de espécies que apresentam respostas rápidas às mudanças nas condições ambientais. Essa capacidade adaptativa tem implicações importantes para a produção de ovos e para o ciclo de vida, especialmente em ambientes transitórios, como corpos d'água temporários. O presente estudo investigou a história de vida e a produção de ovos da espécie Alona guttata Sars, 1862 (Crustacea, Cladocera) coletada em uma lagoa temporária de altitude (Minas Gerais, Brasil). Organismos recém eclodidos foram observados (em condições de laboratório) em relação ao tempo de maturação, número de ovos produzidos por fêmea e tempo de sobrevivência. Os neonatos levaram em média 8 dias para atingir o primeiro estágio de maturação. As fêmeas produziram 2 ovos por ninhada e geraram uma média de 10,95 ± 6,41 neonatos durante todo o ciclo de vida. A. guttata apresentou uma média de 30,9 ± 8,1 dias de sobrevivência. O rápido desenvolvimento, o pouco tempo para a produção de ovos e o ciclo de vida longo são adaptações importantes às condições ambientais adversas de ambientes aquáticos temporários, que podem contribuir para a rápida colonização de Alona guttata em ecossistemas transitórios.

ABSTRACT Objective: To perform a systematic literature review to analyze existing data on the neurological effects of coronavirus on newborns. Data sources: We followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P), and searched the PubMed and Embase platforms for the keywords [brain damage OR pregnancy OR developmental outcomes] and [coronavirus OR SARS-CoV-2 OR SARS-CoV OR MERS-CoV] between January 1, 2000 and June 1, 2020. Data synthesis: Twenty-three reports described the course of pregnant women exposed to SARS-CoV-2, SARS-CoV, or MERS-CoV during the gestational period, eight to SARS-CoV-2, eight to SARS-CoV, and seven to MERS-CoV. No data were found on abnormalities in brain development or on a direct link between the virus and neurological abnormalities in the human embryo, fetus, or children. Spontaneous miscarriage, stillbirth, and termination of pregnancy were some complications connected with SARS/MERS-CoV infection. SARS-CoV-2 is not currently associated with complications in the gestational period. Conclusions: The literature has no data associating exposure to coronavirus during pregnancy with brain malformations and neurodevelopmental disorders. However, despite the lack of reports, monitoring the development of children exposed to SARS-CoV-2 is essential given the risk of complications in pregnant women and the potential neuroinvasive and neurotropic properties found in previous strains.

RESUMO Objetivo: Realizar uma revisão sistemática da literatura para analisar os dados existentes sobre os efeitos neurológicos do coronavírus em recém-nascidos. Fontes de dados: Esta revisão seguiu as diretrizes dos Principais Itens para Relatar Revisões Sistemáticas e Meta-Análises (Preferred Reported Items for Systematic Review - PRISMA) e dos Protocolos dos Principais Itens para Relatar Revisões Sistemáticas e Meta-Análises (Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols - PRISMA-P), pesquisando as plataformas PubMed e Embase pelas palavras-chave [brain damage (dano cerebral) OU pregnancy (gravidez) OU developmental outcomes (alterações de desenvolvimento)] e [coronavirus (coronavírus) OU SARS-CoV-2 OU SARS-CoV OU MERS-CoV] entre 1º de janeiro de 2000 e 1º de junho de 2020. Síntese dos dados: Vinte e três relatos descreveram a evolução de mulheres grávidas expostas ao SARS-CoV-2, SARS-CoV ou MERS-CoV durante o período gestacional, oito ao SARS-CoV-2, oito ao SARS-CoV e sete ao MERS-CoV. Não foram encontrados dados sobre anormalidades no desenvolvimento cerebral ou sobre uma ligação direta entre o vírus e alterações neurológicas no embrião, feto ou crianças. Abortamento espontâneo, morte fetal e interrupção da gravidez foram algumas das complicações relacionadas à infecção por SARS/MERS-CoV. Até o momento, o SARS-CoV-2 não está associado a complicações no período gestacional. Conclusões: Não há dados na literatura que associem a exposição ao coronavírus durante a gravidez com malformações cerebrais e distúrbios do neurodesenvolvimento. No entanto, apesar da falta de relatos, o monitoramento do desenvolvimento de crianças expostas ao SARS-CoV-2 é essencial devido ao risco de complicações em gestantes e às potenciais propriedades neuroinvasivas e neurotrópicas encontradas em cepas anteriores.

Objective: to analyze epidemic curves based on mathematical models for the state of Mato Grosso do Sul and the impacts of population density on COVID-19 transmission. Method: the linear, polynomial and exponential regression model was used to make the numerical adjustment of the respective curves empirical. Result: it was found that the models used describe very well the empirical curves in which they were tested. In particular, the polynomial model is able to identify with reasonable reliability the appearance of the inflection point in the accumulated curves, which corresponds to the maximum point of the respective daily curves. The analysis indicates a weak positive correlation between infection, mortality, lethality and deaths from COVID-19 with population density, as revealed by the correlation and analysis of R2 . Conclusion: the models are very effective in describing the COVID-19 and epidemic curves in the estimation of important epidemiological parameters, such as peak case curves and daily deaths, allowing practical and efficient monitoring of the evolution of the epidemic.

Objetivo: analizar curvas epidémicas basadas en modelos matemáticos para el estado de Mato Grosso do Sul y los impactos de la densidad de población en la transmisión de COVID-19. Método: se utilizó el modelo de regresión lineal, polinomial y exponencial para hacer el ajuste numérico valor de las respectivas curvas empíricas. Resultados: se encontró que los modelos utilizados describen muy bien las curvas empíricas en las que fueron probados. En particular, el modelo polinomial es capaz de identificar con razonable fiabilidad la aparición del punto de inflexión en las curvas acumuladas, que corresponde al punto máximo de las respectivas curvas diarias. El análisis indica una correlación positiva débil entre la infección, la mortalidad, la letalidad y las muertes por COVID-19 con la densidad de población, según lo revelado por la correlación y el análisis de R2 .Conclusión: los modelos son muy efectivos para describir el COVID-19 y curvas epidémicas en la estimación de parámetros epidemiológicos importantes, como las curvas de casos máximos y las muertes diarias, lo que permite un seguimiento práctico y eficaz de la evolución de la epidemia.

Aim: One of the main factors that play a pivotal role in the transmission of COVID-19 from human to human is saliva; according to the subject's importance, the present study aimed to evaluate the potential of transmission via the saliva of coronavirus disease. Methods: PubMed, ISI, Embase, Scopus, Medicine have been used until September 2020 to search for articles. Therefore, EndNote X9 used to manage electronic resources. A 95% confidence interval (CI) effect size, fixed effect model, Inverse-variance methods have been calculated. The positive rate of SARS-CoV2 assessed with meta analysis. To deal with potential heterogeneity, random effects were used, and I2 showed heterogeneity. I2 values above 50% signified moderate-to-high heterogeneity. The Meta-analysis has been evaluated with Stata/MP v.16 (the fastest version of Stata) statistical software. Results: According to the study's purpose, in the initial search with keywords, 19 articles were found, the full text of 3 studies was reviewed, and finally, three studies were selected. The positive rate of SARS-CoV2 was 86% (86%; 95% CI 67 %-100%). Conclusion: saliva can be a non-invasive specimen type for diagnosis of COVID-19. Dentists should be aware that saliva plays a major role in the transmission of COVID-19 from human to human, and failure to follow prevention protocols can contaminate them

Aim: This study evaluated, by the application of questionnaires, the impact of the COVID-19 pandemic on the clinical routine and inspection by the competent authorities, on the flow of patients in the office, as well as on possible changes in Endodontic treatment costs and the amounts charged to patients. Methods: This cross-sectional study was conducted from May 2nd, 2020 to May 6th, 2020, using an online questionnaire with a convenience sample. The inclusion criterion was professionals who perform endodontic treatments in daily clinical practice and who professional setting is private practice. The questionnaire brought questions about the impact on costs and the amount charged to the patient. Results: A total of 1042 questionnaires were answered from all the different states of Brazil, by professional who usually perform Endodontic treatment, and who is working in private practice. A total of 1010 (96.9%) respondents affirm it was necessary to modify the protective equipment in endodontic treatment due to pandemic and longer intervals between appointments was cited by 922 (88.5%), economically affecting the dental practice. There was no association between routine changes and economic impacts with gender, professional experience, area of residence or education level. Conclusion: In conclusion, most dental professionals recognized changes in the routine of endodontic treatment during the COVID-19 pandemic. They have a perception of increase in endodontic costs, and reduction in the volume of patients

Aim: This cross-sectional study aimed to investigate where Brazilian dental students seek information about COVID-19 by a self-administered web-based questionnaire. Methods: A social network campaign on Instagram was raised to approach the target population. The dental students responded to a multiple-response question asking where or with whom they get information about COVID-19. The possible answers were government official websites or health and education institutions websites, TV Programs, professors, social media, scientific articles, health professionals, and family members. The data were analyzed by descriptive statistics, and the frequency distributions of responses were evaluated by gender, age, type of institution, and year of enrollment. Results: A total of 833 valid responses were received. The main source of information used by the dental students were government official websites or health and education institutions websites, which were reported by 739 (88.7%) participants. In the sequence, 477 (57.3%) participants chose health professionals while 468 (56.2%) chose scientific articles as information sources. The use of social media was reported by 451 (54.1%) students, while TV programs were information sources used by 332 (39.9%) students. The least used information sources were professors, reported by 317 (38.1%) students, and family members, chosen only by 65 (7.8%) participants. Conclusion: Brazilian dental students rely on multiple information sources to stay informed about COVID-19, mainly focusing their information-seeking behavior on governmental and health professional's websites
