Hematological problems are associated with Coronavirus disease 2019 (COVID-19). Respiratory impairment is the higher point studied, although without experimental studies related to the oxygen transport performed by erythrocytes. Therefore, we decided to investigate if erythrocytes from COVID-19 patients have their functionality changed. The case-control study included hospitalized patients with a positive real-time polymerase chain reaction (RT-PCR) result admitted to University Hospital. Volunteers (negative RT-PCR results) were recruited as a control group. Thus, we assessed different erythrocytes parameters, oxidative stress markers, and biophysical studies using whole blood and isolated hemoglobin. We found a decrease of 51% in oxygen uptake and reduced antioxidant enzyme activity in COVID-19 patients compared to controls. Raman spectrometry showed structural changes in the hemoglobin and lipids of the erythrocytes from COVID-19 patients; thus, these results were consolidated with an increase in Young’s modulus in erythrocytes followed by morphology changes. Besides, isolated hemoglobin from COVID-19 patients has a distinct interaction profile using a ligand model compared to the control. COVID-19 leads to structural, functional, and morphological damage to human erythrocytes. Our data showed structural and molecular changes and induction of oxidative stress in erythrocytes by COVID-19, a new perspective on the contribution of erythrocytes to a respiratory commitment in COVID-19.

ABSTRACT Objective: To evaluate a possible increase of adhesive capsulitis incidence during the COVID-19 pandemic. Methods: A total of 1,983 patients with shoulder disorders were retrospectively analyzed regarding gender, age, development of adhesive capsulitis and comorbidities (systemic arterial hypertension, diabetes mellitus, dyslipidemia, hypothyroidism, hyperthyroidism, depression, and anxiety) in two different periods: from March 2019 to February 2020 and from March 2020 to February 2021. Descriptive and quantitative variables were statistically analyzed. The program used for the calculations was SPSS 17.0 for Windows. Results: During the pandemic, there was a 2.41-fold increase (p < 0.001) in cases of adhesive capsulitis (compared to the previous year). Patients with depression and anxiety had a significantly increased risk by 8.8 (p < 0.001) and 14 (p < 0.001) times, respectively, of developing frozen shoulder (regarding the two periods studied). Conclusion: A significant increase in the incidence of frozen shoulder was observed after the onset of the COVID-19 pandemic in addition to a simultaneous increase of psychosomatic disorders. Prospective studies would help to ratify the idea contained in this research. Level of Evidence III, Observational Cross-Sectional Study.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

Abstract The aim of this study was to evaluate the body yield and quality of fresh and post-freezing filet of male and female fish of inbred and non-inbred AquaAmérica genetic group and the hybrid between the AquaAmérica and Tilamax varieties. Forty fish (20 males and 20 females) of each genetic group were housed in four 48-m3 hapa net cages, getting 120 fish per cage. The fish were housed at 51 days of age and farmed for 269 days. Pre-slaughter weight was higher (P<0.05) in the AquaAmérica × Tilamax males (0.805±0.204 kg) than in the inbred AquaAmérica male (0.643±0.115 kg). Filet yield percentage was higher (P<0.05) in the AquaAmérica × Tilamax males (32.14±4.72%) than in the inbred AquaAmérica (28.15±2.67%) and non-inbred AquaAmérica (29.06±2.80%) males. Head and viscera yield percentages, pH, color values (L*, a* and b*), shear force, drip loss and cooking loss did not differ significantly between the genetic groups and sexes. Alterations in meat quality were observed after freezing. In conclusion, inbreeding in the AquaAmérica variety resulted in reduced slaughter weight for males; AquaAmérica × Tilamax males have a higher filet yield; and filet quality is not influenced by crossing, inbreeding, or sex, but is changed after freezing.

ABSTRACT The article addresses the impacts caused by floodings in the municipality of São Paulo in the eighteenth century, starting in 1750. Our discussion details the reactions of local authorities to the hydrological dynamics of the region in a period before the radical interventions that would occur in the following centuries. We identified seventeen occasions in the period when the São Paulo Municipal Council was compelled to take measures to mitigate the harmful effects of rainwater accumulation, river flooding or excessive runoff from built structures such as fountains, aqueducts, and dikes. The sources demonstrate the recurrence of both the same types of water-caused problems and ways of coping adopted by the Municipal Council, which, as a rule, was only able to act reactively, ordering the execution of repair works. We argue that this very restrained use of the possibilities for technical intervention reflects, on the one hand, the limits of local power and, on the other, the priorities of colonial knowledge itself and the framework of possible relations between society and nature that it determines.

RESUMO O artigo pretende abordar os impactos ocasionados por alagamentos no município de São Paulo no século XVIII, a partir de 1750. Nossa discussão busca expor as reações do poder local à dinâmica hidrológica da região em um momento anterior às severas intervenções que ocorreriam nos séculos seguintes. Identificamos, no período investigado, dezessete ocasiões em que a Câmara Municipal de São Paulo se viu compelida a tomar medidas para mitigar os efeitos danosos do acúmulo de águas pluviais, cheias de rios ou escoamento excessivo a partir de estruturas edificadas como fontes, aquedutos e diques. A documentação demonstra a recorrência tanto dos mesmos tipos de problemas causados pelas águas quanto das formas de enfrentamento adotadas pela Câmara, que, via de regra, só conseguiu agir reativamente, determinando apenas a realização de obras de reparo. Argumentamos que esse emprego muito comedido das possibilidades de intervenção técnica reflete, por um lado, os limites do poder local, e, por outro, as prioridades do próprio conhecimento colonial e do quadro de relações possíveis entre sociedade e natureza que ele determina.

Resumo Objetivos: Avaliar os possíveis impactos da Covid-19 na prática da cirurgia bucomaxilofacial, bem como os protocolos empregados pelos cirurgiões bucomaxilofaciais para minimizar os riscos de contaminação. Método: Foram feitas buscas em diferentes bases de dados até 15 de março de 2021. Foram incluídos artigos relacionados à dinâmica da cirurgia oral no contexto da pandemia de Covid-19. Os artigos foram considerados elegíveis se atendessem aos seguintes critérios de inclusão: estudos observacionais que fornecessem recomendações sobre medidas de cirurgia bucomaxilofacial durante a pandemia de Covid-19 e que analisassem o risco de contaminação de pacientes/profissionais com SARS-CoV-2. Resultados: Sete estudos preencheram os critérios de inclusão e foram selecionados para a presente revisão sistemática. As demandas por equipamentos de proteção individual aumentaram significativamente, estudos relataram a escassez de equipamentos fundamentais, como máscaras FFP2/N95. Foram observadas mudanças significativas na infraestrutura das unidades ambulatoriais, cirúrgicas e de internação e nos próprios protocolos assistenciais. Conclusão: A pandemia de Covid-19 afetou particularmente a rotina dos residentes de cirurgia bucomaxilofacial. Diversas recomendações adicionais para a prática cirúrgica ou para a equipe cirúrgica foram avaliadas e discutidas, como a feitura de cirurgias prioritariamente de urgência e emergência, atendimento e triagem remota de pacientes, adiamento de cirurgias eletivas e novos métodos de ensino em programas de residência em cirurgia bucomaxilofacial. Além disso, a triagem de pacientes e da equipe cirúrgica para Covid-19 é fortemente recomendada.

Abstract Objectives: The aim of this systematic review was to evaluate the possible impacts of COVID-19 on oral and maxillofacial surgery practice, as well as the protocols employed by oral and maxillofacial surgeons to minimize the risks of contamination. Methods: Searches were performed in different databases up to 15 March 2021. Articles related to oral surgery dynamics within the context of the COVID-19 pandemic were included. The articles were considered eligible if they met the following inclusion criteria: observational studies that provided recommendations regarding maxillofacial surgery measures during the COVID-19 pandemic and that analyzed the risk of contamination of patients/professionals with SARS-CoV-2. Results: Seven studies met the inclusion criteria and were selected for the present systematic review. Demands for personal protective equipment increased significantly, with studies reporting the scarcity of fundamental equipment such as FFP2/N95 masks. Significant changes in the infrastructure of outpatient, surgical and inpatient units and in the care protocols themselves were observed. Conclusion: The COVID-19 pandemic particularly affected the routine of oral and maxillofacial surgery residents. Several additional recommendations for surgical practice or for the surgical team were evaluated and discussed, such as performing primarily urgent and emergency surgeries, remote patient care and screening, postponing elective surgeries, and new teaching methods in oral and maxillofacial surgery residency programs. In addition, screening of patients and of the surgery team for COVID-19 is strongly recommended.

Abstract Clinker is the raw material used in the manufacture of cement. However, this material is very harmful to the environment, since it is estimated that for every ton of clinker produced, about 1.0 ton of CO2 is released into the atmosphere. For this reason, alternatives were sought for the use of other materials that are less harmful to the environment. This has led to the use of industrial by-products with the aim of increasing their use and thus reducing the amount of carbon released into the atmosphere. Blast furnace slag is a by-product used in the manufacture of some cementitious products. The aim of this research is to conduct a study on the use of slag as an additive for cement or concrete. The mortar samples were tested according to Brazilian, American and European technical standards. Physical, chemical and compressive strength tests were carried out which confirmed the possibility of using the slag without chemical or thermal activation.

RESUMO A avaliação estrutural do cérebro, feita por meio dos exames de neuroimagem, é a forma mais utilizada de ferramenta diagnóstica e de acompanhamento das doenças neurodegenerativas. Técnicas de imagem mais sofisticadas podem ser necessárias especialmente nas fases mais precoces, antes mesmo do surgimento de quaisquer sintomas, porém costumam ser caras e pouco acessíveis. Sendo assim, é de fundamental importância a busca de biomarcadores não invasivos, de fácil acesso e baixo custo, que possam ser utilizados para rastreio populacional e diagnóstico mais precoce. Nesse cenário, o número de estudos com ênfase em técnicas de imagem para avaliação estrutural da retina em pacientes com doenças neurodegenerativas tem aumentado nos últimos anos. A retina apresenta similaridade embriológica, histológica, bioquímica, microvascular e neurotransmissora com o córtex cerebral, tornando-se assim um biomarcador único e promissor nas doenças neurodegenerativas. A tomografia de coerência óptica é uma moderna técnica de imagem não invasiva que gera imagens seccionais bidimensionais de alta resolução e medidas volumétricas tridimensionais reprodutivas do disco óptico e da mácula. Essa tecnologia é amplamente utilizada na prática oftalmológica para o diagnóstico e o seguimento de diversas doenças oculares, como glaucoma, retinopatia diabética e degeneração macular relacionada à idade. A redução da espessura da camada de fibras nervosas da retina e das camadas de células ganglionares em pacientes com doenças neurodegenerativas foi demonstrada em diversos estudos clínicos nos últimos anos. Nesta revisão, abordamos as principais aplicações clínicas da tomografia de coerência óptica nas doenças neurodegenerativas e discutimos o seu papel como potencial biomarcador nessas afecções.

ABSTRACT Structural imaging of the brain is the most widely used diagnostic tool for investigating neurodegenerative diseases. More advanced structural imaging techniques have been applied to early or prodromic phases, but they are expensive and not widely available. Therefore, it is highly desirable to search for noninvasive, easily accessible, low-cost clinical biomarkers suitable for large-scale population screening, in order to focus on making diagnoses at the earliest stages of the disease. In this scenario, imaging studies focusing on the structures of the retina have increasingly been used for evaluating neurodegenerative diseases. The retina shares embryological, histological, biochemical, microvascular and neurotransmitter similarities with the cerebral cortex, thus making it a uniquely promising biomarker for neurodegenerative diseases. Optical coherence tomography is a modern noninvasive imaging technique that provides high-resolution two-dimensional cross-sectional images and quantitative reproducible three-dimensional volumetric measurements of the optic nerve head and retina. This technology is widely used in ophthalmology practice for diagnosing and following up several eye diseases, such as glaucoma, diabetic retinopathy and age-related macular degeneration. Its clinical impact on neurodegenerative diseases has raised enormous interest over recent years, as several clinical studies have demonstrated that these diseases give rise to reduced thickness of the inner retinal nerve fiber layer, mainly composed of retinal ganglion cells and their axons. In this review, we aimed to address the clinical utility of optical coherence tomography for diagnosing and evaluating different neurodegenerative diseases, to show the potential of this noninvasive and easily accessible method.

ABSTRACT Hand-foot-and-mouth disease (HFMD) is a highly contagious viral disease commonly associated to Enteroviruses (EV). During 2018, Brazil faced massive HFMD outbreaks spread across the country. This study aimed to characterize the EV responsible for the HFMD outbreak that occurred in Paraiba State, Brazilian Northeastern region, in 2018, followed by a phylogenetic analysis to detail information on its genetic diversity. A total of 49 serum samples (one from each patient) collected from children ≤ 15 years old, clinically diagnosed with HFMD were tested for EV using conventional RT-PCR and RT-qPCR. EV infection was confirmed in 71.4% (35/49) of samples. The mean and median ages were 1.83 years and one year old, respectively. Twenty-two EV-positive samples were successfully sequenced and classified as EV-A species; 13 samples were also identified with the CV-A6 genotype. The phylogenetic analysis (VP1 region) of three samples revealed that the detected CV-A6 strains belonged to sub-lineage D3. The CV-A6 strains detected here clustered with strains from South America, Europe and West Asia strains that were also involved in HFMD cases during the 2017-2018 seasons, in addition to the previously detected Brazilian CV-A6 strains from 2012 to 2017, suggesting a global co-circulation of a set of different CV-A6 strains introduced in the country at different times. The growing circulation of the emerging CV-A6 associated with HFMD, together with the detection of more severe cases worldwide, suggests the need for a more intense surveillance system of HFMD in Brazil. In addition, this investigation was performed exclusively on serum samples, and the analysis of whole blood samples should be considered and could have shown advantages when employed in the diagnosis of enteroviral HFMD outbreaks.

ABSTRACT. This study aimed to evaluate forage yield, tiller population density, canopy height, nutritional value as well as cattle performance in alternate stocking from three tropical forage cultivars. The experiment followed a randomized block design, in a 3 x 3 factorial scheme with three replications. Three forage cultivars (Marandu, Massai and Xaraés) distributed in nine hectares were evaluated in three dry season periods (transition wet/dry, dry, and end of dry season), with repeated measures over time. The following variables were evaluated: canopy height, leaf: stem ratio, forage mass, leaf mass, stem mass and dead material mass. Total digestible nutrients, crude protein and in vitro dry mass digestibility were evaluated regarding forage nutrition. Animal performance, using 36 eleven-month-old animals (half-blood Nelore), was evaluated by the daily average gain and weight gain by area. During pre-grazing, canopy height presented interaction among forage cultivars and the evaluated periods. The average daily gain showed no interaction among cultivars and period of the year the similarity in animal performance among the cultivars Marandu and Massai show that the Massai grass can be used as an alternative for forage diversification under an alternate management system.

Resumo A trombose de veia porta (TVP) é uma doença na qual ocorre trombose desde os ramos intra-hepáticos da veia porta, podendo se estender até a veia esplênica e/ou veia mesentérica superior, estando associada, na maioria das vezes, à cirrose hepática. A TVP não associada a cirrose é rara. O objetivo deste artigo foi relatar dois casos de TVP não associados à cirrose, que foram tratados com anticoagulação e tiveram evolução clínica satisfatória.

Abstract Portal vein thrombosis (PVT) is a disease in which thrombosis occurs from the intrahepatic branches of the portal vein, and may extend to the splenic vein and/or superior mesenteric vein. It is most often associated with liver cirrhosis. PVT not associated with cirrhosis is rare. The aim of this article is to report two cases of PVT in which it was not associated with cirrhosis. Both were treated with anticoagulation and clinical progress afterwards was good.

Abstract Aim: To evaluate the chronic effects of resistance training on resting blood pressure, handgrip strength, gait speed, and Timed Up and Go test (TUG) in normotensive and hypertensive elderly individuals. Methods: Experimental study based on TREND. Hypertensive patients were diagnosed by an independent doctor. Before and after 12 weeks of progressive resistance training, we evaluated blood pressure, heart rate, body composition, Timed Up and Go test, gait speed, and handgrip strength. Results: Sample consisted of 41 participants divided into two groups (normotensive n = 28; hypertensive n = 13). We observed significant values in the reduction of blood pressure levels only in the group of hypertensive participants. In functionality outcomes, we observed significant values in all tests and both groups. Outcomes contemplate effect sizes ranging from small to moderate. Conclusion: Progressive resistance training lowers resting blood pressure levels, increases handgrip strength, and improves physical functional performance. Although the normotensive group did not show a reduction in blood pressure levels, an improvement was observed in the functional physical tests.

Abstract The objective of this unprecedented research was to evaluate performance traits, carcass yield, meat quality, and hematological parameters of pintado amazônico fish (Pseudoplatystoma reticulatum × Leiarius marmoratus) fed diets containing ractopamine (20 mg kg-1) for different periods, during the final growth phase. The following treatments were evaluated: 45 days without ractopamine supplementation (control diet); 30 days of control diet, followed by 15 days of ractopamine supplementation; 15 days of control diet, followed by 30 days of ractopamine supplementation; and 45 days of ractopamine supplementation. Performance traits, carcass yield and hematological parameters were not significantly influenced by the ractopamine supplementation periods. The pH, L* color and a* color parameters of the filet post-slaughter and the L* color of the filet post-thawing were significantly influenced by the period of supplementation with the additive in the diet. Cooking loss was significantly lower in the fillet of fish that received ractopamine. Ractopamine supplementation at the level of 20 mg kg-1 in the diet of pintado amazônico for 15, 30, or 45 days does not alter their production performance, carcass yield, or hematological parameters, but changes the qualitative traits of their filet.

RESUMO: Nesta investigação - parte constituinte de uma pesquisa doutoral - pretendemos localizar e analisar a utilização do referencial prigoginiano nos trabalhos de Educação em Ciências. Analisamos trabalhos de conclusão de cursos stricto sensu (teses e dissertações), que apresentavam o pensamento-Prigogine como objeto de estudo ou como referencial teórico na área de Educação em Ciências. Para tal, a fonte documental escolhida foi o Catálogo de Teses e Dissertações da Capes. A pesquisa consistiu na aplicação da Análise Textual Discursiva (ATD) no corpus da nossa investigação, em que fomos direcionados pela pergunta fenomenológica “o que é isto que se mostra da utilização do referencial prigoginiano nas pesquisas em Educação em Ciências?”. Tivemos como resultado quatro categorias, as quais são apresentadas e discutidas por meio de metatextos. Observamos que duas dessas categorias carregam uma perspectiva de discussão mais filosófica em sua composição, ao passo que as outras duas categorias se atêm à discussão da localização do referencial prigoginiano nas estruturas das pesquisas que integram o corpus desta investigação. Confirmamos que, apesar da sua relevância, o referencial prigoginiano é pouco ou quase nada utilizado no campo de Educação em Ciências. Por outro lado, argumentamos sobre o quão inovadora, necessária e desafiadora será a construção de trabalhos no campo educacional que tenham Prigogine como referencial teórico.

ABSTRACT: In this investigation - a constituent part of a doctoral research - we aimed to locate and analyze the use of the Prigoginian framework in Science Education works. We analyzed stricto sensu course completion works (theses and dissertations), which had Prigogine-thought as an object of study or as a theoretical reference in the field of Science Teaching. To this end, the documental source chosen was the Capes Theses and Dissertations Catalogue. The research consisted of the application of Discursive Textual Analysis (DTA) in the corpus of our investigation, where we were guided by the phenomenological question “what is this that is shown in the use of the Prigoginian framework in research in Science Education?” As a result we had four categories, which are presented and discussed through metatexts. We observed that two of these categories carry a more philosophical discussion perspective in their composition, while the other two categories focus on the discussion of the location of the Prigoginian reference in the research structures that make up the corpus of this investigation. We confirm that, despite its relevance, the Prigoginian reference is little or almost nothing used in the field of Science Education. In contrast, we argue how innovative, necessary, and challenging will be the construction of works in the educational field that have Prigogine as a theoretical reference.

RESUMEN: En esta investigación, parte constitutiva de una investigación doctoral, pretendemos ubicar y analizar el uso del marco prigoginiano en trabajos de Educación en Ciencias. Se analizaron trabajos de finalización de cursos de postgrado stricto sensu (tesis doctorales y de maestría) que presentaban el pensamiento prigoginiano como objeto de estudio o como referente teórico en el campo de la Educación en Ciencias. Para ello, se eligió como fuente documental el Catálogo de Tesis Doctorales y de Maestría de la Capes. La investigación consistió en la aplicación del Análisis Textual Discursivo (ATD) en el corpus de nuestra investigación, en la cual nos guio la pregunta fenomenológica “¿qué es eso que se muestra en el uso del marco prigoginiano en las investigaciones en Educación en Ciencias?”. Tuvimos como resultado cuatro categorías, las cuales son presentadas y discutidas a través de metatextos. Observamos que dos de estas categorías llevan una perspectiva de discusión más filosófica en su composición, mientras que las otras dos categorías se enfocan en la discusión de la ubicación de la referencia prigoginiana en las estructuras de investigación que componen el corpus de esta investigación. Constatamos que, a pesar de su relevancia, la referencia prigoginiana es poco o casi nada utilizada en el campo de la Educación en Ciencias. Por otro lado, argumentamos cuán innovadora, necesaria y desafiante será la construcción de obras en el campo educativo que tengan a Prigogine como referente teórico.
