In the present work, synthetic slags (FeO-SiO2-CaO-P2O5-Al2O3-TiO2-V2O5 system) mimicking the composition of the slag inclusions of Ipanema were solidified at different cooling rates. FactSage software was used to calculate the slag’s phase equilibria from 500ºC to 1600°C to guide the microstructural characterisation. The samples solidified with slower cooling rates featured wüstite dendrites and a eutectic-like matrix, with intradendritic (Al,V,Ti)-containing iron spinel precipitates in the wüstite. The rapidly solidified slag showed refined wüstite dendrites surrounded by a Fe-O-Si-Ca-containing amorphous single-phase matrix without intradendritic (Al,V,Ti)-containing iron spinel precipitation. The comparison of the calculated phase diagram with the as-cast microstructures showed a few discrepancies. For instance, the FactSage’s database must be updated to consider the simultaneous solubility of Al, V and Ti in the thermodynamic description of the spinel phases, such as FToxid-SP-V, FToxid-SPINA, FToxid-TiSp and (FeO)2(TiO2)(s). Finally, the intradendritic precipitation of (Al,V,Ti)-containing iron spinel phases in the wüstite of the slag inclusions indicated that an Ipanema’s iron artefact was exposed to high service temperatures between 750 and 1050ºC.

ABSTRACT Tamandua Gray, 1825 contains two species of anteaters: Tamandua mexicana (Saussure, 1860), which occurs in southern Mexico, throughout Central America and south to the west of the Andes in South America, and Tamandua tetradactyla (Linnaeus, 1758), widely distributed in South America, from Venezuela to northern Argentina, as well as Trinidad and Tobago. Historically, different coloration patterns have been attributed to the coat of Tamandua, with T. mexicana typically showing a partial or complete dark “vest” on the dorsal portion of the body, whereas T. tetradactyla can show a complete, partial, or absent vest and a coat varying from golden, pale yellow and pale gray to brown or black. These different coat colors are sometimes treated as inherent characteristics of subspecies of Tamandua. Here, we review color variation in Tamandua and describe six chromatic disorders for the genus: albinism, leucism, “brown” variation, melanism (partial and total), xanthochromism (partial and total) and, for the first time for anteaters, erythrism. In addition, we detail the morphological expression and geographic distribution of these anomalies in populations of Tamandua from Central and South America.

Abstract Tropical grasslands have been systematically neglected worldwide in maps, conservation policies, and ecological studies. After eradicating invasive pine trees from a Cerrado reserve in southeastern Brazil, an unprecedented grassy ecosystem arose in recent satellite images. In the field, we confirmed the first record of wet grasslands with termite mounds – locally named campo com murundus ˗ beyond 21°S in the São Paulo state. Besides reporting this occurrence, we sampled the two plant communities forming this peculiar vegetation type (the mounds and the waterlogged matrix around them) to investigate if they are floristically and functionally distinct. We also explored how these two communities relate to those of the surrounding open vegetation types (savanna, dry and wet grassland). Woody plants were recorded on the mounds but not in the matrix, although the two communities share some ground layer species. Compared to the adjacent vegetation types, the mounds were floristically distinct and functionally more balanced in growth forms, dispersal syndrome, and tolerance to waterlogging. We hope this borderline record of campo com murundus can stimulate the search for other unnoticed remnants out of their known occurrence region, triggering efforts for their conservation and studies to improve comprehension of these iconic ecosystems.

Resumo Os campos naturais tropicais têm sido sistematicamente negligenciados em todo o planeta, seja nos mapas, nas políticas de conservação ou em estudos ecológicos. Após controle da invasão por Pinus em unidade de conservação do Cerrado no sudeste do Brasil, um ecossistema graminoso sem registro regional surgiu nas imagens de satélite recentes. Observação em campo resultou no primeiro registro de campo com murundus em latitude superior a 21°S, no estado de São Paulo. Além de relatar essa ocorrência, amostramos as duas comunidades vegetais que formam esse tipo de vegetação peculiar (ocorrendo sobre os murundus e na matriz alagadiça ao redor deles) para investigar se são florística e funcionalmente distintas. Também exploramos como essas duas comunidades estão relacionadas com os tipos de vegetação aberta circundantes (savana, campo seco e campo úmido). Plantas lenhosas foram registradas nos murundus, mas não na matriz, embora as duas comunidades compartilhem algumas espécies do estrato rasteiro. Em comparação com os outros tipos de vegetação adjacentes, os murundus se mostraram floristicamente distintos e funcionalmente mais equilibrados em relação às formas de crescimento, síndrome de dispersão e tolerância ao encharcamento. Esperamos que esse registro limítrofe de campo com murundus possa estimular a busca por outros remanescentes despercebidos fora da região de ocorrência já conhecida, desencadeando esforços para sua conservação e estudos que possam melhorar a compreensão desses ecossistemas icônicos.

Abstract Objective: The clinical cases of patients with multisystem inflammatory syndrome (MIS-C) were analyzed via a systematic review and meta-analysis of the clinical findings, treatments, and possible outcomes of articles retrieved via database searches. Sources: The authors searched the PubMed, Scielo, Web of Science, Science Direct, EMBASA, EBSCO, and Scopus databases for articles containing the keywords “multisystem inflammatory syndrome in children” or “MIS-C” or “PIMS-TS” or “SIMP” and “COVID-19” or “SARS-CoV-2” published between December 1st, 2019 and July 10th, 2021. Patient characteristics, tissue and organ comorbidities, the incidence of symptoms after COVID-19 infection, treatment, and patient evolution in the articles found were evaluated. The data were abstracted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and Newcastle-Ottawa Scale (NOS). Findings: In total, 98 articles (2275 patients) were selected for demographics, clinical treatment, and outcomes of patients diagnosed with MIS-C. The average age of children with MIS-C, 56.8% of whom were male, was of nine years. Fever (100%), gastrointestinal (GI) (82%), and abdominal pain (68%) were the decisive symptoms for the diagnosis of MIS-C. Shock and/or hypotension were common in patients with MIS-C. Cardiac symptoms (66%) predominated over respiratory (39%) and neurological (28%) symptoms. MIS-C treatment followed the common guidelines for treating children with septic shock and Kawasaki disease (KD) and proved to be effective. Conclusions: This meta-analysis highlights the main clinical symptoms used for the diagnosis of MIS-C, the differences between MIS-C and KD, and the severity of the inflammatory process and urgency for hospital care.

RESUMO Racional: Com o aumento do número de operações bariátricas torna-se maior o interesse pelo conhecimento, experiência e habilidades no manejo operatório e anestésico de obesos. A recuperação anestésica é ponto importante na abordagem terapêutica e menos efeitos adversos que retardem a alta são necessários estar em mente da equipe cirúrgica. Objetivo: Comparar técnicas anestésico-analgésicas na era poupadora de opioides através da administração epidural de anestésico local associado à morfina em baixa dose vs. à clonidina e analisar o impacto da analgesia na efetividade da recuperação pós-operatória comparando as duas técnicas. Métodos: Ensaio clínico randomizado e duplo-cego com 66 pacientes candidatos ao bypass gastrojejunal em Y-de-Roux divididos em dois grupos: grupo morfina e grupo clonidina. A analgesia multimodal incluiu na anestesia epidural com ropivacaína 0,375% 20 ml na altura da oitava vértebra torácica a associação de morfina (grupo morfina) em dose de 15 mcg/kg ou de clonidina (grupo clonidina) na dose 1 mcg/kg. Resultados: Os grupos se mostraram homogêneos e foi encontrada significância estatística ao analisar a diferença da dor entre eles no primeiro pós operatório. A dor foi superior no grupo clonidina, como também neste período o resgate analgésico foi melhor neste grupo. Nos demais tempos não houve significância nas diferenças quanto à dor e resgate. O retorno da motilidade intestinal no grupo morfina foi mais precoce no primeiro pós-operatório. Náuseas, vômitos e a alta hospitalar não apresentaram diferenças significativas entre os grupos. Conclusão: A anestesia epidural com morfina em baixa dose permitiu menor dor durante todo internamento com impacto positivo em relação a recuperação dos pacientes.

ABSTRACT Background: As the number of bariatric operations increases, there is a greater interest in knowledge, experience and skills in the operative and anesthetic management of obese people. Anesthetic recovery is an important point in the therapeutic approach and less adverse effects delaying discharge of these patients are necessary to be kept in mind by the surgical team. Aim: To compare anesthetic-analgesic techniques in the opioid-sparing era through epidural administration of local anesthetic associated with low-dose morphine vs. clonidine and analyze the impact of analgesia on the effectiveness of postoperative recovery by comparing these two techniques. Methods: Randomized, double-blind clinical trial with 66 patients candidates for Roux-en-Y gastrojejunal bypass divided into two groups: morphine group and clonidine group. Multimodal analgesia included epidural anesthesia with 0.375% ropivacaine 20 ml at the eighth thoracic vertebra with the association of morphine (morphine group) at a dose of 15 mcg / kg or clonidine (clonidine group) at a dose of 1 mcg / kg. Results: The groups were homogeneous and statistical significance was found when analyzing the difference in pain between them in the first postoperative period. The pain was higher in the clonidine group, as in this period, analgesic rescue was also better in this group. In the other times, there was no significance in the differences regarding pain and rescue. The return of intestinal motility in the morphine group was earlier in the first postoperative period. Nausea, vomiting and hospital discharge did not show significant differences between groups. Conclusion: Epidural anesthesia with low-dose morphine allowed less pain during the entire hospital stay, with a positive impact on patient recovery.

Abstract Antimicrobial activity of honey has lately drawn researchers’ attention, especially due to the fact that its antimicrobial capacity has been proven. The aim of this study was analyzing bactericidal and bacteriostatic action in the pathogenic microorganisms Staphylococcus aureus, Escherichia coli and Candida albicans of honey samples from five regions of the state of Paraná. Candida albicans yeast showed to be more resistant to honey than the bacteria Escherichia coli and Staphylococcus aureus. The minimal inhibitory concentration found for the three microorganisms tested was 12.5% to 25%. The minimal bactericidal concentration, in its turn, was 25% for bacteria and 25% to 50% for yeast. The samples from the Southern area had the best results for both the minimal inhibitory and the bactericidal concentrations. Through physicochemical and phyto-chemical analysis, we observed that several factors are associated to the bactericidal capacity of honey. In conclusion, honey is an excellent bactericidal agent with a great biotechnological potential. Its properties are directly related to its geographic origin, which gives each type of honey its own characteristics.

Abstract INTRODUCTION: In the Belém Metropolitan Region (BMR), Pará State, Brazil, American cutaneous leishmaniasis (ACL) is endemic; however, very little is known regarding its causative agents. Therefore, we used our standard diagnostic approach combined with an RNA polymerase II largest subunit (RNAPOIILS)-polymerase chain reaction (PCR) followed by analysis of restriction fragment length polymorphism (PCR-RFLP) to identify Leishmania spp. ACL agents in this region. METHODS: Thirty-two Leishmania spp. isolates from patients with ACL in the BMR during 1995-2018 were analyzed. Leishmania spp. DNA samples were amplified using the primers RPOR2/RPOF2, and the 615-bp PCR products were subjected to enzymatic digestion using TspRI and HgaI endonucleases. RESULTS: ACL etiological agents in the BMR comprised Leishmania (Viannia) lindenbergi (43.7%) followed by Leishmania (Viannia) lainsoni (34.4%), Leishmania (Leishmania) amazonensis (12.5%), and Leishmania (Viannia) braziliensis (9.4%). CONCLUSIONS: To our knowledge, the results of the study revealed for the first time that L. (V.) lindenbergi and L. (V.) lainsoni are the main ACL agents in BMR.

Resumo Objetivos: Estudar a associação do olho seco com a atividade do lúpus eritematoso sistêmico (LES) e seus danos cumulativos. Verificar se o perfil epidemiológico, de tratamento e de auto anticorpos de pacientes com LES influencia a presença de olho seco. Métodos: Foram estudados 70 pacientes com LES para a presença de olho seco pelo teste de Schirmer, atividade da doença por SLEDAI (SLE Disease Activity Index) e dano cumulativo por SLICC/ACR DI (Clínicas Colaborativas Internacionais de Lúpus Eritematoso Sistêmico/American College of Rheumatology Damage Index). Os pacientes também foram submetidos ao questionário OSDI (índice de doenças da superfície ocular). Os dados epidemiológicos e de tratamento e o perfil de auto anticorpos foram extraídos dos prontuários. Resultados: Olho seco pelo teste de Schirmer esteve presente em 51,4% da amostra. Nenhuma associação da presença de olho seco com SLEDAI e SLICC/ACR DI foi encontrada (p = ns). Os sintomas subjetivos do olho seco medidos por OSDI mostraram uma correlação modesta com SLEDAI (Rho de Spearman = 0,32) . O perfil do tratamento não influenciou na presença de olho seco que era mais comum em uns pacientes mais idosos (p < 0, 1). Anti dsDNA teve uma associação negativa com a presença de teste positivo de Schirmer (p = 0, 8). Conclusões: Olho seco detectado pelo teste de Schirmer em pacientes com LES não tem associação com atividade da doença nem dano cumulativo. Anti dsDNA parece ter um efeito protetor neste contexto.

Abstract Objective: To study the association of dry eye with lupus disease activity and cumulative damage. To verify if epidemiological, treatment and autoantibody profile of SLE (systemic Lupus erythematosus) patients influence the presence of dry eye. Methods: We studied 70 SLE patients for the presence of dry eye by Schirmer test, disease activity by SLEDAI (SLE-Disease activity index) and cumulative damage by SLICC/ACR DI (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index). Patients were also submitted to the OSDI (Ocular Surface Disease Index) questionnaire. Epidemiological and treatment data and autoantibody profile were extracted from the charts. Results: Dry eye by Schirmer test was present in 51.4% of the sample. No association of the presence of dry eye with SLEDAI and SLICC DI were found (p = ns). Subjective symptoms of dry eye measured by OSDI showed a modest correlation with SLEDAI (Spearman rho = 0.32). Treatment profile did not influence in the presence of dry eye that was more common in older patients (p < 0.0001). Anti dsDNA had a negative association with the presence of positive Schirmer test (p = 0.0008). Conclusions: Dry eye detected by Schirmer test in SLE patients has no association with disease activity nor cumulative damage. Anti dsDNA seems to have a protective effect in this context.

Abstract Atom-Transfer Radical Copolymerization (ATRP) of methyl methacrylate (MMA) and ethyl methacrylate (EMA) under different reaction conditions was conducted using Grubbs 1st ( 1) and 2nd (2) generation catalysts. Initially, the study focused on the reactivity of the catalysts in ATRP of EMA individually, then the syntheses of poly(MMA-co-EMA) were also conducted in different mixtures of monomers ([MMA]/[EMA] = 100/200 and [MMA]/[EMA] = 200/100). Conversion and semilogarithmic kinetic plots as a function of time were related to the different catalysts and reaction conditions. The values of Mn and PDI also changed when different catalysts were used in the presence of Al(OiPr)3, and more controlled polymerizations were achieved using 1. In the syntheses of poly(MMA)-co -(EMA), conversion of 60% was reached for both catalysts at different [MMA]/[EMA] ratios for 16 h; however, for shorter time, 4 h, better conversion values were obtained using 1 as catalyst for both [MMA]/[EMA] = 100/200 or 200/100.

Ruthenium benzylidene complexes were evaluated as catalysts in atom-transfer radical polymerization (ATRP) of methyl methacrylate (MMA) under different reaction conditions. The mechanism by which Grubbs 1st and 2nd generation catalysts mediate olefin metathesis has been studied, little is known regarding the mechanism of ATRP reaction promoted by these complexes. Conversion and semilogarithmic kinetic plots as a function of time were correlated to the different catalysts and reaction conditions; especially in the presence of Al(OiPr)3 as additive. Molecular weight (Mn) and polydispersity index (PDI) values changed with different catalysts in the presence or absence of Al(OiPr)3. Kinetic studies by 1H NMR revealed that two complexes in the presence of Al(OiPr)3 are converted into ATRP-active with the dissociation of PCy3, but with the benzylidene group preserved. More controlled polymerizations were achieved using Grubbs 1st and, the presence of Al(OiPr)3 improved the control levels for both catalysts.

RESUMO O pequizeiro fornece frutos tradicionalmente utilizados na culinária goiana e regiões do bioma Cerrado. Partindo da análise da comercialização de pequi na Central de Abastecimento de Goiás S/A (Ceasa - GO) e em feiras locais (Ipameri e Pires do Rio - GO), o presente estudo avalia a importância da espécie e ameaças relacionadas ao extrativismo. Os dados revelaram 12 microrregiões produtoras de pequi no estado, sendo comercializados 5,5 mil toneladas de pequi em 2011, com o preço da caixa variando de 25 a 40 reais. Nas feiras, o preço pago por litro em 2010 foi de cinco reais, com um percentual crescente de interessados na venda desse produto não madeireiro. Chama atenção a variação no preço pago ao pequi e mudanças nas regiões produtoras em Goiás, além da aquisição desse produto de outros estados. Para suprir a demanda crescente de pequi, sugere-se, além do extrativismo responsável, o plantio da espécie no Cerrado, em pomares ou sistemas agroflorestais.

ABSTRACT The pequizeiro provides fruits traditionally used in cooking Goiás and regions of the Cerrado biome. Based on the pequi marketing analysis in CEASA-GO and local fairs (Ipameri and Pires do Rio, GO), this study assesses the importance of the species and threats related to extraction. The data revealed 12 micro-regions producing pequi in the state, being sold 5500 tons of pequi in 2011, with the box price ranging from 25 to 40 reais. The price paid in the fairs per liter in 2010 was five Brazilian Reais, with an increasing percentage of interested in the sale of non-timber product. The variation in the price paid to the pequi and changes producing regions in Goiás is noteworthy, in addition to the purchase of this product from other states. To meet the growing demand of pequi, it is suggested, besides the responsible extraction, planting the species in the cerrado, in orchards or agroforestry systems.

Resumo A atuação laboral na Estratégia Saúde da Família tem trazido uma série de novos desafios bioéticos para os profissionais de saúde.

OBJETIVO: Comparar os resultados clínicos e radiográficos da osteossíntese de fraturas do terço lateral da clavícula com dois métodos: placa T ou âncoras associadas aos fios de Kirschner.MÉTODOS: Foram avaliados 15 pacientes com média de idade de 34,3 anos (19-57) e seguimento médio de 22,7 meses (14-32). Em nove casos foi usada a placa T e em seis casos a fixação coracoclavicular com âncoras no processo coracoide e fios de Kirschner através da articulação acromioclavicular (AC). A avaliação incluiu o escore de Constant, satisfação pessoal e avaliação radiográfica.RESULTADOS: Ambas as modalidades de tratamento obtiveram consolidação em todos os casos. O Grupo 1 apresentou escore de Constant mais elevado (83,4) quando comparado com o Grupo 2 (76,4) p = 0,029. Nenhuma das técnicas apresentou complicações graves, embora complicações leves tenham sido observadas apenas no Grupo 2 (80%), a maioria delas a migração do fio de Kirschner e infecção superficial.CONCLUSÃO: O tratamento cirúrgico das fraturas da clavícula distal com placa T proporciona a mesma taxa de consolidação da fixação coracoclavicular com âncoras no coracoide e fios de Kirschner através da articulação AC e melhores resultados clínicos.NÍVEL DE EVIDÊNCIA: Nível III, estudo retrospectivo comparativo, estudo terapêutico.

OBJECTIVE: To compare the clinical and radiographic results from osteosynthesis of fractures of the lateral third of the clavicle, using two methods: T plates or anchors together with Kirschner wires.METHODS: Fifteen patients of mean age 34.3 years (range: 19-57) and mean follow-up 22.7 months (range: 14-32) were evaluated. In nine cases, a T plate was used; and in six cases, coracoclavicular fixation was used with anchors in the coracoid process and Kirschner wires through the acromioclavicular joint. The evaluation included the Constant score, personal satisfaction and radiographic assessment.RESULTS: Both types of treatment achieved consolidation in all cases. Group 1 presented a higher Constant score (83.4) than that of Group 2 (76.4) (p = 0.029). Neither of the techniques presented any severe complications, and mild complications were only observed in Group 2 (80%), mostly consisting of migration of the Kirschner wire and superficial infection.CONCLUSION: Surgical treatment of fractures of the distal clavicle using T plates provided the same consolidation rate as shown by coracoclavicular fixation with anchors in the coracoid process and Kirschner wires through the acromioclavicular joint, and better clinical results.LEVEL OF EVIDENCE: Level III evidence was obtained. Comparative retrospective study and therapeutic study were performed.
