RESUMO. A infecção pelo vírus SARS-CoV-2 pode levar a sintomas neurológicos na fase aguda e na fase de COVID longa. Esses sintomas geralmente envolvem cognição, sono, distúrbios do olfato, manifestações psiquiátricas, dor de cabeça e outros. Esta condição é mais comumente descrita em adultos jovens e mulheres. A sintomatologia pode acompanhar casos graves ou leves da doença. A importância desta questão reside na elevada prevalência de sintomas neurológicos na fase de COVID longa, o que acarreta morbilidade significativa nesta população. Além disso, tal condição está associada a elevados custos de cuidados de saúde, com algumas estimativas em torno de 3,7 trilhões de dólares americanos. Nesta revisão, descrevemos sequencialmente o conhecimento atual sobre os sintomas neurológicos mais prevalentes na COVID longa, bem como sua fisiopatologia e possíveis biomarcadores.

ABSTRACT. Infection with the SARS-CoV-2 virus can lead to neurological symptoms in the acute phase and in the Long COVID phase. These symptoms usually involve cognition, sleep, smell disorders, psychiatric manifestations, headache and others. This condition is more commonly described in young adults and women. This symptomatology can follow severe or mild cases of the disease. The importance of this issue resides in the high prevalence of neurological symptoms in the Long COVID phase, which entails significant morbidity in this population. In addition, such a condition is associated with high health care costs, with some estimates hovering around 3.7 trillion US dollars. In this review, we will sequentially describe the current knowledge about the most prevalent neurological symptoms in Long COVID, as well as their pathophysiology and possible biomarkers.

RESUMO: O objetivo do presente trabalho foi o de criar uma ferramenta para mensurar imagens ultrassonográficas da área do olho de lombo em ovinos. Foram capturadas 121 imagens ultrassonográficas de ovinos, a partir das quais foram segmentadas regiões de interesse utilizando o algoritmo u-net. As métricas adotadas para avaliar as segmentações automáticas foram Dicescore e Interseção sobre União. Por fim, foi realizada análise de regressão utilizando os algoritmos AdaBoost Regressor e Random Forest Regressor e o ajuste dos modelos foi avaliado por meio de quadrado médio dos resíduos, erro absoluto médio e coeficiente de determinação (R²). Os valores obtidos para a métrica Dice foram 0,94, e para Interseção sobre União foi 0,89, demonstrando uma alta similaridade entre os valores reais e previstos, variando de 0 a 1. Os valores de quadrado médio dos resíduos, erro absoluto médio e coeficiente de determinação do modelo de regressores indicaram o melhor ajuste para o Random Forest Regressor. O algoritmo U-Net segmentou com eficiência as imagens ultrassonográficas do músculo Longissimus Dorsi, com maior precisão que as medidas realizadas pelo especialista. Essa eficiente segmentação permitiu a padronização das medidas de área de olho de lombo e, consequentemente, a fenotipagem de ovinos de corte em larga escala.

ABSTRACT: The present research created a tool to measure ultrasound images of the rib eye area in sheep. One hundred twenty-one ultrasound images of sheep were captured, with regions of interest segmented using the U-Net algorithm. The metrics adopted to evaluate automatic segmentations were Dicescore and intersection over union. Finally, a regression analysis was performed using the AdaBoost Regressor and Random Forest Regressor algorithms and the fit of the models was evaluated using the Mean Square Residuals, mean absolute error and coefficient of determination. The values obtained for the Dice metric were 0.94, and for Intersection over Union it was 0.89, demonstrating a high similarity between the actual and predicted values, ranging from 0 to 1. The values of Mean Quadratic Residuals, mean absolute error and coefficient The determination of the regressor models indicated the best fit for the Random Forest Regressor. The U-Net algorithm efficiently segmented ultrasound images of the Longissimus Dorsi muscle, with greater precision than the measurements performed by the specialist. This efficient segmentation allowed the standardization of rib eye area measurements and, consequently, the phenotyping of beef sheep on a large scale.

Abstract Biodiesel serves as a biodegradable, non-toxic, and renewable fuel option that offers an alternative to traditional fossil fuels. This study aimed to examine the impact of elevating biodiesel content to 20% and 50% within regular diesel, with a focus on comprehending how these fuel mixtures influence variations in soot composition using Raman spectroscopy. The soot samples under analysis originated from commercial S10 diesel, as well as fuel blends containing 20% and 50% portions of sunflower and macaúba biodiesel, whereupon the use of this methodology for these fuels characterizes the novelty of this work. The outcomes derived from analyzing the soot samples revealed distinct characteristics in the G, D1, D3, and D4 bands. The ratio between the intensities of these D and G bands is closely indicative of the soot's structure. Consequently, this ratio was analyzed in this investigation to assess the effects of biodiesel concentration and engine rotation speed on soot characteristics. The conclusions found in this study indicated that there was minimal variation in the spectral characteristics of the soot samples across the different fuels and varying engine speeds. As a result, it is inferred that increasing the proportion of biodiesel in commercial diesel S10 did not have a significant impact on the structural composition of soot. biodegradable nontoxic, nontoxic non toxic, toxic non-toxic 20 50 spectroscopy S S1 work D1 D3 soots s structure Consequently speeds result 2 5

Abstract Background Patients with immune-mediated rheumatic diseases (IMRDs) have been prioritized for COVID-19 vaccination to mitigate the infection severity risks. Patients with rheumatoid arthritis (RA) are at a high risk of severe COVID-19 outcomes, especially those under immunosuppression or with associated comorbidities. However, few studies have assessed the safety of the COVID-19 vaccine in patients with RA. Objective To evaluate the safety of vaccines against SARS-CoV-2 in patients with RA. Methods This data are from the study “Safety and Efficacy on COVID-19 Vaccine in Rheumatic Diseases,” a Brazilian multicentric prospective phase IV study to evaluate COVID-19 vaccine in IMRDs in Brazil. Adverse events (AEs) in patients with RA of all centers were assessed after two doses of ChAdOx1 (Oxford/AstraZeneca) or CoronaVac (Sinovac/Butantan). Stratification of postvaccination AEs was performed using a diary, filled out daily and returned at the end of 28 days for each dose. Results A total of 188 patients with RA were include, 90% female. CoronaVac was used in 109 patients and ChAdOx1 in 79. Only mild AEs were observed, mainly after the first dose. The most common AEs after the first dose were pain at the injection (46,7%), headache (39,4%), arthralgia (39,4%), myalgia (30,5%) and fatigue (26,6%), and ChAdOx1 had a higher frequency of pain at the injection (66% vs 32 %, p < 0.001) arthralgia (62% vs 22%, p < 0.001) and myalgia (45% vs 20%, p < 0.001) compared to CoronaVac. The more common AEs after the second dose were pain at the injection (37%), arthralgia (31%), myalgia (23%), headache (21%) and fatigue (18%). Arthralgia (41,4% vs 25%, p = 0.02) and pain at injection (51,4% vs 27%, p = 0.001) were more common with ChAdOx1. No serious AEs were related. With Regard to RA activity level, no significant difference was observed between the three time periods for both COVID-19 vaccines. Conclusion In the comparison between the two immunizers in patients with RA, local reactions and musculoskeletal symptoms were more frequent with ChAdOx1 than with CoronaVac, especially after the first dose. In summary, the AE occurred mainly after the first dose, and were mild, like previous data from others immunizing agents in patients with rheumatoid arthritis.

SUMMARY: The COVID-19 pandemic caused several changes in the teaching of human anatomy, among them the use of different teaching methodologies based on E-learning. However, studies evaluating electronic tools have not provided clear evidence of effective student learning. Thus, this was the first study to evaluate medical students after completing human anatomy courses in the E- learning modality. We recruited first term (Group A, n=25) and second term (Group B, n=13) medical students. We applied a practical assessment based on 50 human anatomy markingson real anatomical specimens and cadavers, to be completed in Questionnaire 01 (Phase I). After detecting low scores on Questionnaire 01 by both groups, we applied a practical and face-to-face tutoring system for 14 days (Phase II). Afterwards, we re-evaluated both groups by repeating the same scores (Questionnaire 02, Phase III). According to the paired analysis of questionnaires 01 and 02 by Student's T-test, both groups showed significant increase in the final scores obtained in questionnaire 02 (Phase III). The evidence showed that the remote format lecture system weakened the learning and retention process of basic anatomical knowledge by medical students. On the other hand, in-person practical teaching proved to be efficient in the formative process of the students, a fact proven by the significant increase in the scores of the students in the 02 questionnaire, for both groups.

RESUMEN: La pandemia por COVID-19 provocó varios cambios en la enseñanza de la anatomía humana, entre ellos el uso de diferentes metodologías de enseñanza basadas en E-learning. Sin embargo, los estudios que evalúan las herramientas electrónicas no han proporcionado evidencia clara de un aprendizaje efectivo de los estudiantes. Este fue el primer estudio que evaluó a estudiantes de medicina luego de cursar cursos de anatomía humana en la modalidad E-learning. Reclutamos estudiantes de medicina de primer término (Grupo A, n=25) y segundo término (Grupo B, n=13). Se aplicó una evaluación práctica basada en 50 marcas de anatomía humana sobre especímenes anatómicos reales y cadáveres, para ser completado en el Cuestionario 01 (Fase I). Tras detectar puntuaciones bajas en el Cuestionario 01 por parte de ambos grupos, se aplicó un sistema de tutorías prácticas y presenciales durante 14 días (Fase II). Posteriormente, reevaluamos ambos grupos repitiendo las mismas puntuaciones (Cuestionario 02, Fase III). Según el análisis apareado de los cuestionarios 01 y 02 por la prueba T de Student, ambos grupos mostraron aumento significativo en los puntajes finales obtenidos en el cuestionario 02 (Fase III). La evidencia mostró que el sistema de conferencias en formato remoto debilitó el proceso de aprendizaje y retención de conocimientos anatómicos básicos por parte de los estudiantes de medicina. Por otro lado, la docencia práctica presencial demostró ser eficiente en el proceso formativo de los alumnos, hecho que demuestra el aumento significativo de las puntuaciones de los alumnos en el cuestionario 02, para ambos grupos.

RESUMEN: Las proteínas S100 pertenecen al grupo de proteínas fijadoras de calcio y están presentes en actividades reguladoras fisiológicas intracelulares y extracelulares, como la diferenciación celular, y actúan en procesos patológicos inflamatorios y neoplásicos. Recientemente, sus expresiones en el sistema nervioso han sido ampliamente estudiadas, buscando dilucidar su acción a nivel del tálamo: una estructura del sistema nervioso central que forma parte de importantes circuitos, como el somatosensorial, conductual, de memoria y cognitivo, así como además de ser responsable de la transmisión y regulación de la información a la corteza cerebral. Este artículo es una revisión integradora de la literatura científica, que analizó 12 estudios presentes en Pubmed. El análisis mostró que la relación de las proteínas S100 y el tálamo ha sido descrita en procesos neoplásicos, trastornos mentales, hipoxia, trauma, estrés, infección, enfermedad de Parkinson y epilepsia. En resumen, es posible concluir que esta familia de proteínas es relevante como marcador en procesos de lesión talámica, requiriendo más estudios para comprender mejor su significado clínico, preclínico y su valor pronóstico.

SUMMARY: S100 proteins belong group of calcium-binding proteins and are present in physiological intracellular and extracellular regulatory activities, such as cell differentiation, and act in inflammatory and neoplastic pathological processes. Recently, its expressions in the nervous system have been extensively studied, seeking to elucidate its action at the level of the thalamus: A structure of the central nervous system that is part of important circuits, such as somatosensory, behavioral, memory and cognitive, as well as being responsible for the transmission and regulation of information to the cerebral cortex. This article is an integrative review of scientific literature, which analyzed 12 studies present in Pubmed. The analysis showed that the relationship of S100 proteins and the thalamus has been described in neoplastic processes, mental disorders, hypoxia, trauma, stress, infection, Parkinson's disease and epilepsy. In summary, it is possible to conclude that this protein family is relevant as a marker in processes of thalamic injury, requiring further studies to better understand its clinical, preclinical meanings and its prognostic value.

Resumo Fundamento Tem sido observado um grande avanço nas técnicas e nos dispositivos para a realização de intervenções coronárias percutâneas (ICP) em oclusões totais coronarianas crônicas (OTC), mas existem poucos dados da prática do mundo real em países em desenvolvimento. Objetivos Relatar as características clínicas e angiográficas, os aspectos dos procedimentos e os resultados clínicos da ICP de OTC em centros dedicados a esse procedimento no Brasil. Métodos Os pacientes incluídos foram submetidos à ICP de OTC em centros participantes do LATAM CTO Registry, um registro multicêntrico latino-americano dedicado à coleta prospectiva desses dados. Os critérios de inclusão foram procedimentos realizados no Brasil, idade acima de 18 anos e presença de OTC com tentativa de ICP. A definição de OTC foi lesão de 100% em uma artéria coronária epicárdica, conhecida ou estimada como tendo pelo menos 3 meses de evolução. Resultados Foram incluídos dados de 1.196 ICPs de OTC. Os procedimentos foram realizados principalmente para controle da angina (85%) e/ou tratamento de uma grande área isquêmica (24%).

Abstract Background Major advances have been seen in techniques and devices for performing percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs), but there are limited real-world practice data from developing countries. Objectives To report clinical and angiographic characteristics, procedural aspects, and clinical outcomes of CTO PCI performed at dedicated centers in Brazil. Methods Included patients underwent CTO PCI at centers participating in the LATAM CTO Registry, a Latin American multicenter registry dedicated to prospective collection of these data. Inclusion criteria were procedures performed in Brazil, age 18 years or over, and presence of CTO with PCI attempt. CTO was defined as a 100% lesion in an epicardial coronary artery, known or estimated to have lasted at least 3 months. Results Data on 1196 CTO PCIs were included. Procedures were performed primarily for angina control (85%) and/or treatment of moderate/severe ischemia (24%). Technical success rate was 84%, being achieved with antegrade wire approaches in 81% of procedures, antegrade dissection and re-entry in 9%, and retrograde approaches in 10%. In-hospital adverse cardiovascular events occurred in 2.3% of cases, with a mortality rate of 0.75%. Conclusions CTOs can be treated effectively in Brazil by using PCI, with low complication rates. The scientific and technological development observed in this area in the past decade is reflected in the clinical practice of dedicated Brazilian centers.

RESUMO: Objetivo: Identificar padrões espaciais em casos de lactentes com alterações de crescimento e desenvolvimento relacionadas à infecção pelo vírus Zika e outras etiologias infecciosas (neste trabalho denominado de síndrome congênita pelo vírus Zika), notificados no Maranhão de 2015 a 2018 e sua relação com variáveis socioeconômicas e demográficas. Métodos: Estudo ecológico de casos suspeitos notificados de síndrome congênita pelo vírus Zika nos 217 municípios do Maranhão, Brasil. Calculou-se a autocorrelação espacial pelos índices de Moran local e global (I) univariado e bivariado da taxa de detecção de casos suspeitos de síndrome congênita pelo vírus Zika com índice de desenvolvimento humano municipal, densidade demográfica, índice de Gini e tempo de emancipação político-administrativa dos municípios. O índice de Moran local foi calculado para localizar clusters com autocorrelação espacial significativa. Resultados: Houve autocorrelação espacial na análise univariada da taxa municipal de detecção de casos suspeitos de síndrome congênita pelo vírus Zika (I=0,494; p=0,001) e, na análise bivariada, correlação positiva da taxa de detecção de casos suspeitos com índice de desenvolvimento humano municipal (I=0,252; p=0,001), densidade demográfica (I=0,338; p=0,001) e tempo de emancipação dos municípios (I=0,134; p=0,001). Não houve correlação significativa da taxa de detecção de casos suspeitos com o índice de Gini (I= -0,033; p=0,131). Cinco clusters de alta detecção de casos suspeitos foram encontrados em áreas distintas do estado. Conclusões: Os municípios com maior índice de desenvolvimento humano municipal, maior densidade demográfica e mais tempo de emancipação político-administrativa tiveram mais casos suspeitos notificados de síndrome congênita pelo vírus Zika.

ABSTRACT: Objective: To identify spatial patterns in cases of changes in growth and development related to Zika virus infection and other infectious etiologies (denominated Zika virus congenital syndrome in this study) reported in Maranhão from 2015 to 2018 and their relation with socioeconomic and demographic variables. Methods: Ecological study of notified Zika virus congenital syndrome cases in the 217 cities of Maranhão, Brasil. Spatial autocorrelation was calculated using GeoDa 1.14 software and the local and global (I) Moran’s index in univariate and bivariate analyses on Zika virus congenital syndrome incidence rate with Municipal Human Development Index (MHDI), population density, Gini coefficient and the cities’ time of administrative political emancipation. Local Moran’s Index was calculated to identify clusters with significant spatial autocorrelation. Results: Spatial autocorrelation was checked in univariate analysis of the incidence rate of Zika virus congenital syndrome (I=0,494; p=0,001) and positive correlation in bivariate analysis of the incidence rate with Municipal Human Development Index (I=0,252; p=0,001), population density (I=0,338; p=0,001) and the cities’ time of administrative political emancipation (I=0,134; p=0,001). The correlation between incidence rate with Gini coefficient was not significant (I= -0,033; p=0,131). Five high-incidence clusters were found in distinct areas of the state. Conclusions: Cities with higher MHDI, higher population density and more years of administrative political emancipation had more cases of Zika virus congenital syndrome notified.

Resumo O objetivo do presente estudo foi comparar o uso de diferentes espaçamentos e clones de eucalipto na estocagem de carbono em 6 (seis) sistemas silvipastoris (SSP), localizados em Porto Firme - MG. Em campo foram utilizados experimentos contendo 6 (seis) SSP, com os clones GG100, I144, I224, híbridos de Eucalyptus grandis x Eucalyptus urophylla, nos espaçamentos de 6m x 4m e 8m x 4m, nas idades de 60 e 96 meses. O inventário florestal realizado foi do tipo censo, onde todas as árvores tiveram sua circunferência a 1,30 m de altura (CAP) mensuradas e foram separadas em classes diamétricas. O volume foi estimado baseado no modelo Spurr. A densidade da madeira foi calculada pelo método de imersão em água e o estoque de carbono pelo fator de 0,47. O material genético I224, no espaçamento de 6m x 4m, foi aquele com maior potencial de estocagem de carbono. A densidade básica para os três clones, no espaçamento de 6m x 4m, não variou estatisticamente. Porém, no espaçamento de 8m x 4m, para os materiais genéticos GG100 e I224, houve diferença. Foi possível concluir que o material genético I224, no espaçamento 6m x 4m (24 m2 por planta) possui o maior potencial de estocagem de carbono e que os SSP com eucalipto contribuem para uma agricultura de baixa emissão de carbono e mitigação das mudanças climáticas.

Abstract This study aimed to compare the use of different eucalypt spacing and clones in carbon storage in six silvopastoral systems (SSP) located in Porto Firme - MG. Experiments containing six SSP were used in the field, with clones GG100, I144, and I224, hybrids of Eucalyptus grandis x Eucalyptus urophylla, in the spacing of 6m x 4m and 8m x 4m, at the ages of 60 and 96 months. The forest inventory carried out was of the census type, where all the trees had their circumference at 1,30 m in height (CAP) measured and separated into diametric classes. The volume was estimated based on the Spurr model. The wood density was calculated by the method of immersion in water and the carbon stock by the factor of 0,47. The genetic material I224, spaced 6m x 4m, had the highest potential for carbon storage. The basic density for the three clones, in 6m x 4m spacing, did not vary statistically, however, in 8m x 4m spacing, for the genetic materials GG100 and I224, there was a difference. It was possible to conclude that the genetic material I224, in 6m x 4m spacing (24 m2 per plant), has the highest potential for carbon storage and that SSP with eucalypt contributes to low-carbon agriculture and mitigation of climate change.

Abstract: En | Text: En | PDF: En

Sclareol (SC) is arousing great interest due to its cytostatic and cytotoxic activities in several cancer cell lines. However, its hydrophobicity is a limiting factor for its in vivo administration. One way to solve this problem is through nanoencapsulation. Therefore, solid lipid nanoparticles (SLN-SC) and nanostructured lipid carriers (NLC-SC) loaded with SC were produced and compared regarding their physicochemical properties. NLC-SC showed better SC encapsulation than SLN-SC and was chosen to be compared with free SC in human cancer cell lines (MDA-MB-231 and HCT-116). Free SC had slightly higher cytotoxicity than NLC-SC and produced subdiploid DNA content in both cell lines. On the other hand, NLC-SC led to subdiploid content in MDA-MB-231 cells and G2/M checkpoint arrest in HCT-116 cells. These findings suggest that SC encapsulation in NLC is a way to allow the in vivo administration of SC and might alter its biological properties
