Abstract Austrodiplostomum Szidat & Nani, 1951 is a genus of parasitic digenetic trematodes widely distributed in the Neotropical region. Infects a wide variety of species, families and requests for freshwater fish. We identify samples of Austrodiplostomum sp, based on metacercariae isolates from eyes of tambaqui (Colossoma macropomum), a fish of high commercial importance in Brazil, and widely consumed by the population of the northern region. The sequences obtained clustered with A. compactum. This is the first report of the occurrence of diplostomids in farmed tambaqui in Amazonia.

RESUMO A infecção pelo Toxoplasma gondii pode causar manifestações oculares tanto após a sua forma congênita quanto a sua forma adquirida. Reportamos aqui dois casos de toxoplasmose congênita sintomática com envolvimento ocular em irmãos não gêmeos, com intervalo de 2 anos entre gestações. A transmissão vertical da toxoplasmose em gestações sucessivas, outrora considerada impossível, é um evento plausível mesmo em indivíduos imunocompetentes.

ABSTRACT Toxoplasma gondii infection can cause ocular manifestations after acquired and congenital disease. We report two cases of symptomatic congenital toxoplasmosis with ocular involvement in non-twin siblings, with a 2-year interval between pregnancies. Vertical transmission of toxoplasmosis in successive pregnancies, which was once considered impossible, is now found to be plausible even in immunocompetent subjects.

Abstract The process of producing eucalyptus seedlings hosts a complex of arthropods, which can highlight sucking insects, such as aphids. The aim was to study aphids on seedlings and mini-stumps in a clonal mini-garden of eucalyptus in Brazil, through their identification, studies of population growth and host preference of these insects in different species of eucalyptus. In this study, it is registered, for the first time in Eucalyptus spp. in Brazil, the species Aphis gossypii Glover 1887 and Aphis spiraecola Patch 1914 (Hemiptera: Aphididae). Aphid colonies were observed in April and March 2018 infesting Eucalyptus pellita and Eucalyptus brassiana seedlings in the greenhouse of the Federal University of Piauí (UFPI), in Teresina, Piauí; and in a clonal mini-garden of Eucalyptus spp. from the PlantBem seedling production nursery in Monsenhor Gil, Piauí. The population growth of Aphis spiraecola was evaluated using the instantaneous growth rate (ri) in six species of eucalyptus (Eucalyptus pellita, Eucalyptus grandis, Eucalyptus brassiana, Eucalyptus urophylla, Eucalyptus tereticornis e Corymbia citriodora), as well as the aphid host preference for these species was tested through a choice test. Only in Corymbia citriodora there was no population growth of Aphis spiraecola. Aphis spiraecola showed less host preference for Corymbia citriodora, while Eucalyptus pellita and Eucalyptus urophylla were the preferred species. This is the first record of Aphis gossypii in a clonal mini-garden of eucalyptus and of Aphis spiraecola in seedlings of Eucalyptus spp. in Brazil.

Resumo No processo de produção de mudas de eucalipto ocorre um complexo de artrópodes, podendo destacar os insetos sugadores, como pulgões. Objetivou-se estudar pulgões em mudas e minicepas em minijardim clonal de eucalipto no Brasil, através de sua identificação, estudos de crescimento populacional e preferência hospedeira desses insetos em diferentes espécies de eucalipto. Neste estudo registra-se, pela primeira vez em Eucalyptus spp. no Brasil, as espécies Aphis gossypii Glover, 1887 e Aphis spiraecola Patch, 1914 (Hemiptera: Aphididae). Colônias de pulgões foram observadas em abril e março de 2018 infestando mudas de Eucalyptus pellita F. Muell e Eucalyptus brassiana S.T. Blake na casa de vegetação da Universidade Federal do Piauí (UFPI), em Teresina, Piauí; e em minijardim clonal de Eucalyptus spp. do viveiro de produção de mudas PlantBem, em Monsenhor Gil, Piauí. O crescimento populacional de Aphis spiraecola foi avaliado através da utilização da taxa instantânea de crescimento (ri) em seis espécies de eucalipto (Eucalyptus pellita, Eucalyptus grandis W.Hill ex Maiden, Eucalyptus brassiana, Eucalyptus urophylla S.T. Blake, Eucalyptus tereticornis Smith e Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Johnson), assim como foi testada a preferência hospedeira do pulgão por essas espécies através de teste com chance de escolha. Apenas em Corymbia citriodora não houve crescimento populacional de A. spiraecola. Aphis spiraecola demonstrou menor preferência hospedeira por Corymbia citriodora, enquanto as espécies Eucalyptus pellita e Eucalyptus urophylla foram as preferidas. Este é o primeiro registro de Aphis gossypii em minijardim clonal de eucalipto e de Aphis spiraecola em mudas de Eucalyptus spp. no Brasil.

Abstract Objectives This analysis describes the protocol of a study with a case-cohort to design to prospectively evaluate the incidence of subclinical atherosclerosis and Cardiovascular Disease (CVD) in Chronic Inflammatory Disease (CID) participants compared to non-diseased ones. Methods A high-risk group for CID was defined based on data collected in all visits on self-reported medical diagnosis, use of medicines, and levels of high-sensitivity C-Reactive Protein >10 mg/L. The comparison group is the Aleatory Cohort Sample (ACS): a group with 10% of participants selected at baseline who represent the entire cohort. In both groups, specific biomarkers for DIC, markers of subclinical atherosclerosis, and CVD morbimortality will be tested using weighted Cox. Results The high-risk group (n = 2,949; aged 53.6 ± 9.2; 65.5% women) and the ACS (n=1543; 52.2±8.8; 54.1% women) were identified. Beyond being older and mostly women, participants in the high-risk group present low average income (29.1% vs. 24.8%, p < 0.0001), higher BMI (Kg/m2) (28.1 vs. 26.9, p < 0.0001), higher waist circumference (cm) (93.3 vs. 91, p < 0.0001), higher frequencies of hypertension (40.2% vs. 34.5%, p < 0.0001), diabetes (20.7% vs. 17%, p = 0.003) depression (5.8% vs. 3.9%, p = 0.007) and higher levels of GlycA a new inflammatory marker (p < 0.0001) compared to the ACS. Conclusions The high-risk group selected mostly women, older, lower-income/education, higher BMI, waist circumference, and of hypertension, diabetes, depression, and higher levels of GlycA when compared to the ACS. The strategy chosen to define the high-risk group seems adequate given that multiple sociodemographic and clinical characteristics are compatible with CID.

Abstract Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.

Abstract Based on an extensive analysis of public databases, we provide an overview of the global scientific output and describe the dynamics of the profound changes in the scientific enterprise during the last decades. The analysis included the scientific production of 53 countries over the 1996-2018 period. During this period, the production of articles per year has tripled. There was a strong correlation between the growth of the global gross domestic product and the increase in the number of articles (R2 = 0.973, P<0.001). Six countries showed a robust increment of their scientific production and are currently among the top 20 in the ranking of world scientific production (China, India, South Korea, Brazil, Turkey, and Iran). The mean annual growth rate was about 12.7% for these six countries. The share of the global scientific production of these countries increased from 7% in 1996 to 27.8% in 2018. Conversely, the participation of the 10 most traditional countries has dropped from 73% to 45% during the same period. In conclusion, we believe that our findings may contribute to further studies aiming to evaluate the impact and changes of the scientific endeavor over the next years in light of the forthcoming new world framework.

Resumo Introdução: Obesidade, diabetes e hipertensão arterial são fatores de risco comuns para doenças renais crônicas (DRC). A DRC surge devido a muitos insultos patológicos, incluindo inflamação e estresse oxidativo, que afetam a função renal e destroem os néfrons. O farelo de arroz (FA) é rico em vitaminas e minerais, e contém uma quantidade significativa de antioxidantes. O objetivo deste estudo foi avaliar o efeito preventivo do FA nos fatores de risco de doenças renais. Métodos: Ratos Wistar machos (±325 g) foram divididos em dois grupos experimentais para receber uma dieta rica em gordura e açúcar (DRGA, n = 8) ou uma dieta rica em gordura e açúcar com farelo de arroz (DRGA + FA, n = 8) por 20 semanas. Ao final, foram analisados a função renal, composição corporal, parâmetros metabólicos, marcadores renais inflamatórios e de estresse oxidativo. Resultados: FA preveniu a obesidade [IA (DRGA= 9,92 ± 1,19 vs. DRGA + FA= 6,62 ± 0. 78)], resistência à insulina [HOMA (DRGA= 83 ± 8 vs DRGA + FA= 42 ± 11)], dislipidemia [TG (DRGA= 167 ± 41 vs. DRGA + FA=92 ± 40)], inflamação [FNT-α (DRGA= 80 ± 12 vs. DRGA + FA=57 ± 14), IL-6 (903 ± 274 vs. DRGA + FA= 535 ± 277)], estresse oxidativo [carbonilação de proteína (DRGA= 3. 38 ± 0,18 vs. DRGA + FA=2,68 ± 0,29), RAGE (DRGA=702 ± 36 vs. DRGA + FA=570 ± 190)], e doença renal [relação proteína/creatinina (DRGA=1,10 ± 0,38 vs. DRGA + FA=0,49 ± 0,16)]. Conclusão: Em conclusão, o farelo de arroz preveniu doenças renais através da modulação dos fatores de risco.

Abstract Introduction: Obesity, diabetes, and hypertension are common risk factors for chronic kidney disease (CKD). CKD arises due to many pathological insults, including inflammation and oxidative stress, which affect renal function and destroy nephrons. Rice bran (RB) is rich in vitamins and minerals, and contains signiﬁcant amount of antioxidants. The aim of this study was to evaluate the preventive effect of RB on renal disease risk factors. Methods: Male Wistar rats (±325 g) were divided into two experimental groups to received a high sugar-fat diet (HSF, n = 8) or high sugar-fat diet with rice bran (HSF + RB, n = 8) for 20 weeks. At the end, renal function, body composition, metabolic parameters, renal inflammatory and oxidative stress markers were analyzed. Results: RB prevented obesity [AI (HSF= 9.92 ± 1.19 vs HSF + RB= 6.62 ± 0.78)], insulin resistance [HOMA (HSF= 83 ± 8 vs. HSF + RB= 42 ± 11)], dyslipidemia [TG (HSF= 167 ± 41 vs. HSF + RB=92 ± 40)], inflammation [TNF-α (HSF= 80 ± 12 vs. HSF + RB=57 ± 14), IL-6 (903 ± 274 vs. HSF + RB=535 ± 277)], oxidative stress [protein carbonylation (HSF= 3.38 ± 0.18 vs. HSF + RB=2.68 ± 0.29), RAGE (HSF=702 ± 36 vs. RSF + RB=570 ± 190)], and renal disease [protein/creatinine ratio (HSF=1.10 ± 0.38 vs. HSF + RB=0.49 ± 0.16)]. Conclusion: In conclusion, rice bran prevented renal disease by modulating risk factors.

ABSTRACT Objective: The aim of this review was to summarize the most common extrapulmonary manifestations in pediatric patients with COVID-19, as well as to discuss clinical, epidemiological, and pathophysiological aspects of these clinical presentations in children. Source of data: An extensive search of literature was performed in order to identify pediatric cases with extrapulmonary manifestations between January 1, 2020 and June 21, 2020. Generic keywords, such as “Novel coronavirus” or “Novel coronavirus 2019” or “2019 nCoV” or “COVID-19” or “SARS-CoV-2” were searched on PubMed database, associated either with age filters or generic pediatric terms. Summary of findings: A total of 28 articles, including 199 patients, were considered suitable to review and data extraction. The main findings were summarized in tables. The main non-pulmonary manifestations in pediatric patients, in decreasing order of frequency, were gastrointestinal, renal, cardiovascular, neurological, hematological and lymphatic, cutaneous, hepatic, ocular, olfactory, and gustatory. Multisystem impairment and Kawasaki-like disease were also described. Conclusions: Differences in immune response of children and variations of tissue expression of angiotensin converting enzyme 2, the virus receptor, are likely to influence clinical, epidemiological, and pathophysiological patterns of the disease.

OBJECTIVES: To investigate the expression levels of surface markers of activation (CD38 and HLA-DR), inhibition (PD-1, TIGIT and CD57) and co-stimulation (CD28 and CD127) on CD4+ T cells of children/adolescents with vertical HIV infection (HI patients) and HIV-uninfected (HU) controls vaccinated with the meningococcal C conjugate vaccine (MCC). METHODS: HI patients (n=12), aged 8-17 years, were immunized with two MCC injections, while HU controls (n=9), aged 5.3-10.7 years, received a single MCC dose (as per national recommendation at the time of this study, a single MCC vaccine dose should be given for healthy children and youth aged 1-18 years). The HI patients were categorized according to the combined antiretroviral therapy (cART) treatment. Blood samples were obtained before vaccination, after priming, and after the administration of a booster dose of vaccine to determine the serum bactericidal antibody (SBA) titers and the expression levels of surface markers on CD4+ T cells by flow cytometry. The levels of serum cytokines, IL-4 and CXCL-13 were also measured using Luminex kits. RESULTS: The co-expression of the TIGIT-HLA-DR-CD38 molecules increased in the CD4+ T cells of HI patients/no-cART who also showed a lower frequency of CD127+CD28+ CD4+ T cells than HI patients/cART and HU group subjects. There were significant negative correlations between the frequency of exhausted CD4+ T cells and the SBA response. IL-4 levels were higher in HI patients/cART and positively correlated with SBA titers but negatively associated with the expression of exhaustion markers. Moreover, the CXCL-13 levels were positively correlated with the exhausted CD4+ T cells. CONCLUSION: The results of our study suggest that the co-expression of exhaustion markers and/or loss of co-stimulatory molecules influence the SBA response in HI patients.

Abstract The world is looking forward to a prompt response by the scientific community in order to overcome the first pandemic of the 21st century. This study aimed to provide an overview of scientific output on COVID-19 during its first year. We assembled information regarding 60,830 articles related to COVID-19 indexed in the WoS database from January 24 to December 13, 2020. Only 4 countries accounted for about 60% of the articles (USA, China, Italy, and England) and 12 countries accounted for about 95% of the world scientific output on COVID-19 (USA, China, Italy, England, India, Canada, Germany, Spain, Australia, Brazil, Iran, and Turkey). 25 research centers around the world contributed with more than 500 papers on COVID-19. Papers were scattered throughout 6,133 journals, with 12 journals with > 250 articles. 20 articles (0.03%) have already received more than the 1,000 citations. The response of the scientific endeavor to this acute global public health emergency has been fast and robust. The overview provided by the analysis of the scientific response to the pandemic may contribute to further studies aiming to evaluate the impact and changes in the scientific endeavor for the next years in light of the forthcoming new world framework.

Abstract Green synthesis is an efficient method, frequently applied in nanobiotechnology, as it does not use toxic reagents or solvents. Biological organisms, including medicinal plants, have been used successfully for manufacturing of different types of metallic nanoparticles. The aim of this work was to synthesize, characterize and evaluate the antimicrobial activity of silver nanoparticles (AgNPs) obtained from the extract of the pulp, seed and leaves of Annona muricata L. The particle size, polydispersity index, zeta potential, as well as morphological aspects of AgNPs were evaluated. With the data obtained from the analyses, we concluded that the nanoparticles were successfully obtained by a simple and green method using the aqueous extract of the pulp, seeds and leaves of A. muricata. AgNPs obtained by A. muricata pulp extract without exposure to artificial light showed lowest average of hydrodynamic diameter and smallest size at field emission scanning electron microscope (FESEM). In addition, these nanoparticles showed the best polydispersity index (PDI), and zeta potential of - 29.6, which indicates good stability. AgNPs obtained from the extract of the pulp, seed and leaves showed antimicrobial activity, against strains of gram positive and gram negative bacteria, and antifungal activity, compared to the pure extract.

RESUMO A avaliação de acessos em um banco de germoplasma é essencial para determinar os potenciais genitores em programas de conservação, especialmente para árvores nativas. O objetivo do trabalho foi verificar a diversidade genética entre 68 genótipos de Amburana cearensis situados em diferentes localidades no estado de Pernambuco, Brasil. Os padrões genéticos foram avaliados por marcadores moleculares Inter Simple Sequence Repeats (ISSR) e a divergência genética por meio de análises multivariadas empregando-se diferentes métodos de agrupamento. O método de otimização empregado (Tocher) foi concordante com todos os modelos hierárquicos utilizados, onde o agrupamento dos genótipos ocorreu de forma semelhante, especificamente para o acesso BB116, sendo este um importante material genético a ser preservado e estudado. Dentre os vários métodos hierárquicos aplicados, o de Ligação Média apresentou maior poder de discriminação, permitindo a identificação de maior quantidade de grupos divergentes, inferindo assim grande diversidade genética entre os acessos de A. cearensis.

ABSTRACT The evaluation of accessions in a germplasm bank is essential for determining the potential parents in conservation programs, especially for native trees. This study aimed to determine the genetic diversity among 68 Amburana cearensis genotypes from different locations in the state of Pernambuco, Brazil. Their genetic patterns were evaluated by Inter Simple Sequence Repeat (ISSR) molecular markers and genetic divergence was evaluated through multivariate analyses using different clustering methods. The optimization method used (Tocher) was in agreement with all the hierarchical models used, in which clustering of the genotypes occurred similarly, specifically for the accession BB116, which is an important genetic material to be preserved and studied. Among the various hierarchical methods applied, the Average Linkage method exhibited higher discrimination power, allowing identification of a larger number of divergent groups, thus implying wide genetic diversity among A. cearensis accessions.
