ABSTRACT The global reemergence of measles in 2018–2019 reinforces the relevance of high-coverage immunization to maintain the disease elimination. During an outbreak in the Sao Paulo State in 2019, several measles cases were reported in individuals who were adequately vaccinated according to the current immunization schedule recommends. This study aimed to assess measles IgG antibody seropositivity and titers in previously vaccinated adults. A cross-sectional study was conducted at CRIE-HC-FMUSP (Sao Paulo, Brazil) in 2019. It included healthy adults who had received two or more Measles-Mumps-Rubella vaccines (MMR) and excluded individuals with immunocompromising conditions. Measles IgG antibodies were measured and compared by ELISA (Euroimmun®) and chemiluminescence (LIASON®). The association of seropositivity and titers with variables of interest (age, sex, profession, previous measles, number of measles-containing vaccine doses, interval between MMR doses, and time elapsed since the last MMR dose) was analyzed. A total of 162 participants were evaluated, predominantly young (median age 30 years), women (69.8%) and healthcare professionals (61.7%). The median interval between MMR doses was 13.2 years, and the median time since the last dose was 10.4 years. The seropositivity rate was 32.7% by ELISA and 75.3% by CLIA, and a strong positive correlation was found between the tests. Multivariate analyses revealed that age and time since the last dose were independently associated with positivity. Despite being a single-center evaluation, our results suggest that measles seropositivity may be lower than expected in adequately immunized adults. Seropositivity was higher among older individuals and those with a shorter time since the last MMR vaccine dose.

Abstract Objective To perform a systematic review and meta-analysis of studies on maternal, fetal, and neonatal outcomes of women with singleton pregnancies, after spontaneous conception, and with the diagnosis of amniotic sludge before 37 weeks of gestational age. Data Sources We conducted a search on the PubMed, Cochrane, Bireme, and Theses databases until June 2022. Selection of Studies Using the keywords intra-amniotic sludge or fluid sludge or echogenic particles, we found 263 articles, 132 of which were duplicates, and 70 were discarded because they did not meet the inclusion criteria. Data Collection The articles retrieved were analyzed by 2 reviewers; 61 were selected for full-text analysis, 18 were included for a qualitative analysis, and 14, for a quantitative analysis. Data Synthesis Among the maternal outcomes analyzed, there was an increased risk of preterm labor (95% confidence interval [95%CI]: 1.45–2.03), premature rupture of ovular membranes (95%CI: 1.99–3.79), and clinical (95%CI: 1.41–6.19) and histological chorioamnionitis (95%CI: 1.75–3.12). Regarding the fetal outcomes, there was a significant increase in the risk of morbidity (95%CI: 1.80–3.17), mortality (95%CI: 1.14–18.57), admission to the Neonatal Intensive Care Unit (NICU; 95%CI: 1.17–1.95), and neonatal sepsis (95%CI: 2.29–7.55). Conclusion The results of the present study indicate that the presence of amniotic sludge is a risk marker for preterm delivery. Despite the heterogeneity of the studies analyzed, even in patients with other risk factors for prematurity, such as short cervix and previous preterm delivery, the presence of amniotic sludge increases the risk of premature labor. Moreover, antibiotic therapy seems to be a treatment for amniotic sludge, and it may prolong pregnancy.

Resumo Objetivo Realizar revisão sistemática e metanálise de estudos que avaliaram os desfechos maternos, fetais e neonatais em gestantes de gravidez única, após concepção espontânea, e com o diagnóstico de sludge amniótico antes de 37 semanas de idade gestacional. Fontes dos dados Realizou-se uma pesquisa nas bases de dados PubMed, Cochrane, Bireme e Teses até junho de 2022. Seleção dos estudos Usando as palavras-chave intra-amniotic sludge ou fluid sludge ou echogenic particles, foram encontrados 263 artigos, 132 dos quais eram duplicatas, e 70 foram descartados por não corresponderem aos critérios de inclusão. Coleta de dados Os artigos encontrados foram analisados por 2 revisores; 61 foram selecionados para análise de texto completo, 18 foram incluídos em uma análise qualitativa e 14, em uma análise quantitativa. Síntese dos dados Entre os desfechos maternos analisados, houve aumento do risco de trabalho de parto prematuro (intervalo de confiança de 95% [IC95%]: 1.45–2.03), rotura prematura de membranas ovulares (IC95%: 1.99–3.79), e corioamnionite clínica (IC95%: 1.41–6.19) e histológica (IC95%: 1.75–3.12). Em relação aos desfechos fetais, houve aumento significativo do risco de morbidade (IC95%: 1.80–3.17), mortalidade (IC95%: 1.14–18.57), admissão em Unidade de Tratamento Intensivo (UTI) neonatal (IC95%: 1.17–1.95) e sepse neonatal (IC95%: 2.29–7.55). Conclusão Os resultados do presente estudo indicam que a presença de sludge amniótico é um marcador de risco para parto prematuro. Apesar da heterogeneidade dos estudos analisados, até mesmo em pacientes com outros fatores de risco para prematuridade, como colo curto e trabalho de parto prematuro anterior, a presença de sludge amniótico aumenta o risco de trabalho de parto prematuro na gestação. Além do mais, a antibioticoterapia parece ser um tratamento para o sludge amniótico, e pode ser capaz de prolongar a gravidez.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

Abstract Background Takayasu's arteritis (TA) is a vasculitis that affects the aorta and its branches and causes stenosis, occlusion, and aneurysms. Up to 60% of TA patients are associated with cardiac involvement which confers a poor prognosis. Global longitudinal strain (GLS) analysis is an echocardiographic technique that can detect the presence of subclinical systolic dysfunction. Hence, this study aimed to describe the prevalence of subclinical systolic dysfunction in patients with TA using the GLS method and to correlate this finding with disease activity using the ITAS-2010 (Indian Takayasu Activity Score). Methods Thirty patients over 18 years of age who met the American College of Rheumatology (ACR) 1990 criteria for TA were included. The sample was submitted for medical record review, clinical and echocardiographic evaluation, and application of ITAS-2010. The cutoff for systolic dysfunction was GLS > - 20%. Results Of the 30 patients analyzed, 25 (83.3%) were female, and the mean age was 42.6 years (± 13.2). The median time since diagnosis was 7.5 years [range, 3-16.6 years], and the type V angiographic classification was the most prevalent (56.7%). Regarding echocardiographic findings, the median ejection fraction (EF) was 66% [61-71%] and the GLS was - 19.5% [-21.3 to -15.8%]. Although half of the participants had reduced GLS, only two had reduced EF. Eleven patients (33.%) met the criteria for activity. An association was found between disease activity and reduced GLS in eight patients (P = 0.02) using the chi-square test. Conclusion GLS seems to be an instrument capable of the early detection of systolic dysfunction in TA. The association between GLS and disease activity in this study should be confirmed in a study with a larger sample size.

Resumen Introducción. El achiote (Bixa orellana L.) es una especie valiosa debido al contenido de bixina presente en el arilo de sus semillas, pigmento que es utilizado en la industria alimentaria, cosmética y medicinal. La caracterización de germoplasma es el punto de partida para iniciar programas de fitomejoramiento y para identificar la variabilidad genética de un banco de germoplasma. Objetivo. Evaluación de las diferencias fenotípicas y genotípicas de 18 accesiones de achiote del Banco de Germoplasma de la Universidad EARTH. Materiales y métodos. El fenotipo se caracterizó por medio de descriptores generales y botánicos que detallan características morfológicas y productivas de los cultivares. El genotipo se caracterizó a partir del análisis de la región ITS2 del ADN ribosómico para establecer relaciones filogenéticas entre las accesiones y determinar las relaciones entre características fenotípicas y moleculares. También se realizaron ensayos de autopolinización para evaluar la respuesta de las accesiones a este método que condujera a la obtención de líneas puras. Resultados. Los resultados a partir del dendrograma Maximum Parsimony permitieron diferenciar 5 grupos filogenéticos, los cuales poseen una estrecha relación con el grado de espinosidad de las cápsulas. Al condensar el dendrograma a un 50% se obtuvieron 2 grupos diferenciados por la presencia o ausencia de espinas en las cápsulas, esto posiciona a esta característica como la determinante para el agrupamiento de los materiales. Las accesiones con espinas presentan mayor número de semillas por cápsula, mientras que las accesiones sin espinas poseen mayor contenido de bixina y mayor peso de semilla. Los ensayos de autopolinización revelaron una aparente autoincompatibilidad de acción tardía en algunas accesiones. Conclusión. Esta investigación generó información sobre la identificación de las accesiones, como una primera fase encaminada a la obtención de líneas homocigotas para conservar la identidad genética de las accesiones del Banco de Germoplasma de la Universidad EARTH.

Abstract Introduction. Achiote (Bixa orellana L.) is a valuable species due to the bixin content present in the aril of its seeds; this pigment is used in the food, cosmetic and medicinal industries. Germplasm characterization is the starting point to initiate breeding programs and to identify the genetic variability of a germplasm bank. Objective. This project evaluated the phenotypic and genotypic differences of 18 achiote accessions from the EARTH University Germplasm Bank. Materials and methods. Phenotype was characterized by general and botanical descriptors detailing morphological and productive characteristics of the cultivars. Genotype was characterized based on analysis of the ITS2 region of ribosomal DNA to establish phylogenetic relationships among accessions and to determine relationships between phenotypic and molecular characteristics. Self-pollination trials were also carried out to evaluate the response of the accessions to this method leading to the obtention of pure lines. Results. The results from the Maximum Parsimony dendrogram allowed to differentiate five phylogenetic groups, which are closely related to the degree of spinosity of the capsules. By condensing the dendrogram to 50%, 2 groups were obtained, differentiated by the presence or absence of spines in the capsules, which positions this trait as a determinant for the grouping of materials. Accessions with spines had a higher number of seeds per capsule, while accessions without spines had a higher bixin content and higher seed weight. Self-pollination assays revealed apparent late-acting self-incompatibility in some accessions. Conclusion. This study generated information on the identification of the accessions and is a first phase aimed at obtaining homozygous lines to preserve the genetic identity of the accessions in the EARTH University Germplasm Bank.

Resumen: Introducción: Los síntomas depresivos son comunes en pacientes quirúrgicos de edad avanzada y se asocian con resultados negativos. Aunque la medicación pueda aliviar los síntomas, sólo el 50% de los pacientes que están envejeciendo alcanzan la remisión usando tratamientos convencionales. Se ha demostrado que la ketamina mejora rápidamente la depresión, sin embargo, su uso y tolerabilidad en pacientes mayores no ha sido estudiada ampliamente. Material y métodos: Se realizó un estudio aleatorizado, doble ciego, comparativo en pacientes de 60 años o más que requirieron cirugía oftalmológica. Un grupo experimental recibió 0.5 mg/kg de ketamina, mientras que el grupo control recibió solución de NaCl al 0.9%. Ambos grupos recibieron un régimen estandarizado de sedación consciente. La severidad de los síntomas depresivos fue evaluada usando la versión acortada de la escala de depresión geriátrica (GDS-SF) antes y después de la exposición a la infusión de la ketamina, la tolerabilidad también fue evaluada. Un modelo de análisis de varianza univariada de medidas repetidas (ANOVA) examinó la dirección de los cambios en la gravedad de los síntomas depresivos entre los grupos. Resultados: 90 pacientes fueron aleatorizados. Se observó, una reducción significativa en la severidad de los síntomas después de la infusión de la ketamina (cambio de la media desde el valor basal: -1.6 versus -0.3 en el grupo de control; p = 0.003). No surgieron diferencias entre los grupos en la presencia de efectos adversos con la infusión de ketamina. Conclusiones: Una sola infusión de ketamina en pacientes geriátricos sometidos a cirugía oftalmológica se asocia con la mejoría de síntomas depresivos en las primeras 24 horas de exposición al fármaco con un buen perfil de tolerabilidad.

Abstract: Introduction: Depressive symptoms are common in elderly surgical patients and are associated with negative outcomes. Although medication can relieve symptoms, only 50% of patients achieve remission using conventional treatments. Recently, ketamine has been shown to improve depression rapidly. However, its use and tolerability in elderly patients has not been widely studied. Material and methods: We conducted a randomized, double-blind, comparative study in patients aged 60 and over who required ophthalmological surgery. Experimental group received 0.5 mg/kg ketamine, whereas the control group received NaCl solution at 0.9%. Both groups received a standardized regimen of conscious sedation. Depressive symptom severity was assessed using the Geriatric Depression Scale-Short Form (GDS-SF) before and after exposure to ketamine infusion; tolerability was also evaluated. A repeated univariate analysis of variance (ANOVA) model examined the direction of changes in depressive symptom severity among groups. Results: 90 patients were randomized. A significant reduction in symptom severity was observed after ketamine infusion (mean change from baseline: -1.6 vs -0.3 in the control group; p = 0.003). No differences emerged between groups in the presence of adverse effects with ketamine infusion. Conclusions: A single infusion of ketamine in elderly patients undergoing ophthalmological surgery is associated with improved depressive symptoms in the first 24 hours of exposure to the drug with a good tolerability profile.

Abstract Introduction: High blood pressure (HBP) in informal workers could be explained, by their working and environmental conditions, habits and lifestyles. Objective: To determine working and environmental conditions, habits and lifestyles, which contribute to the explanation of HBP in informal workers in the downtown area in Medellin, Colombia, 2016. Methodology: Cross-sectional descriptive study with analytical intent. Primary source of information: a census of 686 workers in 2016, after obtaining informed consent. Working and environmental conditions, habits, lifestyles and self-report of HBP were investigated. Univariate, bivariate and multivariate analyzes were performed. Statistical tests show 95% confidence and 5% error. A group of workers participated in the design and execution of the fieldwork. Project approved by the Institutional Ethics Committee of Universidad CES, Medellín September 2015. Results: 20,26% of the workers had HBP. Age 50 (±11,76) years old, and 23,5 years as street vendors, 81,5% work>8 hours a day; 17,2% smoked cigarettes, 23,7% used saltshakers at the table and 28,9% were sedentary. Greater hypertension at older age (PR=12.35), greater seniority in the job (PR=1,73) and considered themselves obese (PR=2,61), and lower HBP for those who did not consume liquor (PR=0,48). Greater HBP is explained in people consuming fried foods (PR=3.14.IC=1,64; 6.00), being between 30-44 (PR=10,71. CI:5,00;22,94) and 45 to 59 years old (PR=2,69.CI: 1.66; 4.37), and a lower HBP for those considered as overweight (PR=0,54. IC=0.34; 0.78). Conclusion: working conditions, habits and lifestyles contribute to the explanation of HBP. These are some characteristics that contribute to configure labor vulnerability in this working population.

Resumen La neuroinmunología es una disciplina que cada vez amplía más sus horizontes en la comprensión de las enfermedades neurológicas. Contemporáneamente, y a la luz de los nexos fisiopatológicos de las enfermedades neurológicas y la inmunología, se han planteado enfoques diagnósticos y terapéuticos específicos. A pesar de los importantes avances de esta disciplina, existen múltiples dilemas que le conciernen y se filtran en la práctica clínica. En esta revisión, se presentan y discuten 15 controversias, las cuales se construyen con la información clínica disponible más actualizada. Los temas incluidos son: disminución de esteroides en recaídas de esclerosis múltiple; recomendaciones terapéuticas en esclerosis múltiple a la luz de la pandemia por el SARS-CoV-2; evidencia de vacunación en esclerosis múltiple y en otras enfermedades desmielinizantes; panorama actual del síndrome clínico y radiológico aislado; y fallas terapéuticas en esclerosis múltiple; además, criterios para suspender las terapias modificadoras de la enfermedad; evidencia del manejo en recaídas leves; recomendaciones para la profilaxis contra Strongyloides stercolaris; utilidad de un segundo ciclo de inmunoglobulina en el síndrome de Guillain-Barré; criterios para diferenciar una polineuropatía crónica desmielinizante inflamatoria de inicio agudo de un síndrome de Guillain-Barré y, utilidad de la enzima convertidora de angiotensina en neurosarcoidosis. En cada una de las controversias, se presenta la problemática general y se ofrecen recomendaciones específicas que pueden adoptarse en la práctica clínica diaria.

Abstract Neuroimmunology is a discipline that increasingly broadens its horizons in the understanding of neurological diseases. At the same time, and in front of the pathophysiological links of neurological diseases and immunology, specific diagnostic and therapeutic approaches have been proposed. Despite the important advances in this discipline, there are multiple dilemmas that concern and filter into clinical practice. This article presents 15 controversies and a discussion about them, which are built with the most up-to-date evidence available. The topics included in this review are: steroid decline in relapses of multiple sclerosis; therapeutic recommendations in MS in light of the SARS-CoV-2 pandemic; evidence of vaccination in multiple sclerosis and other demyelinating diseases; overview current situation of isolated clinical and radiological syndrome; therapeutic failure in multiple sclerosis, as well as criteria for suspension of disease-modifying therapies; evidence of the management of mild relapses in multiple sclerosis; recommendations for prophylaxis against Strongyloides stercolaris; usefulness of a second course of immunoglobulin in the Guillain-Barré syndrome; criteria to differentiate an acute-onset inflammatory demyelinating chronic polyneuropathy versus Guillain-Barré syndrome; and, the utility of angiotensin-converting enzyme in neurosarcoidosis. In each of the controversies, the general problem is presented, and specific recommendations are offered that can be adopted in daily clinical practice.

ABSTRACT Academic activities such as conferences are very important for research and development, however, carbon emissions derived from face-to-face events have been shown to be much higher than those produced by online events. The aim of this work was to estimate CO2 emissions generated by the 5th National Congress and 1st International Congress of Environmental Sciences "Environmental Sciences in the Anthropocene". Emissions from direct use of computers and software (emissions from computers, emissions from data transfer) and emissions from other sources (meetings of the organizers, searches and visits to the website, use of external monitors and lamps), as well as emissions avoided by air and land transport. The congress emitted 4.8 tCO2eq and avoided 33 tCO2eq. The development of online or hybrid events is more environmentally sustainable and could be more accessible to a greater number of people.

RESUMEN Las actividades académicas, como los congresos, son muy importantes para la investigación y el desarrollo; sin embargo, las emisiones de carbono derivadas de la realización de eventos presenciales han mostrado estar muy por encima de las que producen eventos en línea. El objetivo de este trabajo fue estimar las emisiones generadas por el 5º Congreso Nacional y 1º Internacional de Ciencias Ambientales “Las Ciencias Ambientales en el Antropoceno”, celebrado virtualmente, en su mayor parte. Se estimaron las emisiones del uso directo de computadores y de software (emisiones de los computadores, emisiones de la transferencia de los datos) y las emisiones de otras fuentes (reuniones de los organizadores, búsquedas y visitas a la página Web, uso de monitores externos y lámparas), así como las emisiones evitadas por transporte aéreo y terrestre. El congreso emitió 4,8 tCO2eq y evitó 33 tCO2eq. El desarrollo de eventos online o híbridos es más sostenible ambientalmente y podría ser más accesibles, a un mayor número de personas.

SUMMARY Introduction: Medullary thyroid carcinoma (MTC) is a rare neuroendocrine malignant tumor derived from the parafollicular cells or thyroid C cells. At the time of diagnosis, over 50 % of patients have lymph node metastases, and 10 % have distant metastases. Prognosis is largely dependent on tumor stage and, therefore, early diagnosis is essential. Objective: The aim of this work is to present an updated review of the diagnostic approach for MTC. Summary: Thyroid ultrasound is the main tool used for thyroid nodule stratification; however, most studies have focused on papillary thyroid carcinoma. In MTC, ultrasonographic findings suggestive of malignancy are usually less frequent and this could delay diagnosis and treatment. Therefore, ultrasound examination should be combined with additional diagnostic techniques. The sensitivity of the fine-needle aspiration cytology is generally low for these types of tumors and when MTC is suspected, it is recommended to perform immunohistochemical for calcitonin and measurement of calcitonin in washout fluid of thyroid nodule aspirate. Serum calcitonin is the most sensitive marker for diagnosing this condition; however, its routine measurement in the evaluation of thyroid nodule is controversial. Serum calcitonin levels are related to C-cell mass and the presence of lymph node metastases. When these levels are above 500 pg/mL suggest distant metastatic disease and additional imaging procedures are indicated. Genetic testing should be offered to all patients because 25 % of these carcinomas are hereditary and are part of multiple endocrine neoplasia type 2 syndrome associated with a germline RET mutation.

RESUMEN: Introducción: El carcinoma medular de tiroides (CMT) es un tumor maligno neuroendocrino poco frecuente derivado de las células parafoliculares o células C del tiroides. En el momento del diagnóstico presentan metástasis ganglionares más del 50 % y a distancia el 10 %. Su pronóstico depende en gran parte del estadio del tumor, por lo que su diagnóstico temprano es fundamental. Objetivo: El objetivo de este trabajo es realizar una revisión actualizada sobre el abordaje diagnóstico del CMT. Síntesis: La ecografía es la principal herramienta en la estratificación del nódulo tiroideo, pero la mayor parte de los estudios se han centrado en el carcinoma papilar de tiroides. En el caso del CMT las características ecográficas sospechosas de malignidad suelen ser menos frecuentes y esto podría conducir a un retraso diagnóstico y terapéutico, por lo que se debe combinar con técnicas diagnósticas adicionales. En estos tumores la sensibilidad del estudio citológico del nódulo mediante punción aspiración con aguja fina generalmente es baja, y en aquellos casos de sospecha de CMT se recomienda realizar inmunohistoquímica para calcitonina y determinar la calcitonina en el aspirado de la punción. La calcitonina plasmática es el marcador más sensible para el diagnóstico de estos pacientes, pero su determinación rutinaria en el estudio del nódulo tiroideo es controvertida. Sus niveles se relacionan con la masa de células C y la presencia de metástasis ganglionares. Si son superiores a 500 pg/ml se recomienda realizar estudio de extensión con pruebas de imagen complementarias por sospecha de enfermedad metastásica. Es importante solicitar estudio genético a todos los pacientes, ya que el 25 % son hereditarios formando parte de la neoplasia endocrina múltiple tipo 2 asociada a mutación en el gen RET.

RESUMEN Para aumentar la disponibilidad de nutrientes y mejorar la productividad de los cultivos, se introducen fertilizantes químicos en el suelo, aunque la fijación biológica de nitrógeno contribuye globalmente con 180 millones de toneladas métricas de amoníaco al año, lo que es comparable al aporte actual de nitrógeno antropogénico. De esta forma, el presente estudio tuvo como objetivo evaluar el efecto de la interacción de Azospyrillum brasilense y Bradyrhizobium japonicum con diferentes niveles de nitrógeno sobre el rendimiento y la viabilidad económica del cultivo de tomate. Se utilizó un diseño experimental de parcelas divididas, siendo la dosis de fertilización nitrogenada la parcela mayor (100% de la dosis, 50% de la dosis y 0% de la dosis) y la parcela menor con bacterias fijadoras de nitrógeno (100 cc ha-1, 200 cc ha-1, 300 cc ha-1) con cuatro bloques internos aleatorios y cinco plantas como unidad experimental. Las variables evaluadas fueron: producción por planta, rendimiento/ha, número de frutos/planta y peso promedio de fruto. Finalmente, se realizó el análisis económico según la combinación de los tratamientos. Los resultados obtenidos mostraron que la mezcla de bacterias fijadoras de nitrógeno (BFN) (Azospyrillum brasilense y Bradyrhizobium japonicum) a una dosis de 100 cc ha-1, incrementó significativamente la producción de tomate cuando no se aplicó nitrógeno (urea). La aplicación de BFN en combinación con niveles adecuados de nitrógeno favorece la sostenibilidad del tomate.

ABSTRACT To increase the availability of nutrients and improve crop productivity, chemical fertilizers are introduced to the soil, although the biological fixation of nitrogen contributes globally with 180 million metric tons of ammonia per year, which is comparable to current contribution of anthropogenic nitrogen. In this way, the present study aimed to evaluate the effect of the interaction of Azospyrillum brasilense and Bradyrhizobium japonicum with different levels of nitrogen on the yield and economic viability of the tomato crop. An experimental design of divided plots was used, with the nitrogen fertilization dose being the largest plot (100% of the dose, 50% of the dose and 0% of the dose) and the minor plot of nitrogen-fixing bacteria (100 cc ha-1, 200 cc ha-1, 300 cc ha-1) with four random internal blocks and five plants as experimental unit. The variables evaluated were: production per plant, yield/ha, number of fruits/plant and average fruit weight. Finally, the economic analysis was performed according to the combination of the treatments. The results obtained showed that the mixture of nitrogen-fixing bacteria (BFN) (Azospyrillum brasilense and Bradyrhizobium japonicum) at a dose of 100 cc ha-1, significantly increased tomato production when nitrogen (urea) was not applied. The application of BFN in combination with adequate levels of nitrogen favors the sustainability of the tomato.

Resumo Este trabalho teve como objetivo avaliar a influência da interface de uma restauração adesiva na difusão do peróxido de hidrogênio (H2O2), toxicidade indireta e expressão de mediadores pró-inflamatórios por células odontoblastóides, após clareamento dental em consultório. Cavidades dentárias preparadas em discos de esmalte / dentina foram restauradas com adesivo e submetidas ou não à degradação hidrolítica (HD). Um gel clareador com 35% H2O2 (WG) foi aplicado por 45 min em discos restaurados e não restaurados adaptados às câmaras pulpares artificiais dando origem aos grupos: SD- discos intactos (controle); SD / HP - Discos intactos clareados; RT / HP - discos restaurados e clareados; e RT / HD / HP - discos restaurados, clareados e submetidos a HD. Os extratos (meio de cultura + componentes WG difundidos através da interface esmalte/dentina/restauração) foram coletados e aplicados em células odontoblastóides MDPC-23. Foi avaliada a quantidade de H2O2 nos extratos, bem como a viabilidade (CV), morfologia (CM) e expressão gênica de mediadores inflamatórios (TNF-α e COX-2) pelas células pulpares expostas aos extratos (ANOVA e testes de Tukey; 5% de significância). Todos os grupos clareados apresentaram menor CV do que SD (controle; p <0,05). A maior redução CV e expressão gênica de TNF-α e COX-2 foi observada no grupo RT / HD / HP em comparação com SD / HP e RT / HP (controle; p <0,05). Alterações na CM ocorreram em todos os grupos clareados. A intensidade desses efeitos celulares teve relação direta com a quantidade de H2O2 nos extratos. Concluímos que a presença de uma cavidade contendo restauração adesiva aumenta a difusão de H2O2 após o clareamento em consultório, o que, por sua vez, aumenta a toxicidade indireta dessa terapia e desencadeia a expressão de mediadores pró-inflamatórios pelas células pulpares MDPC-23.

Abstract This paper aimed to assess the influence of adhesive restoration interface on the diffusion of hydrogen peroxide (H2O2), indirect toxicity, and pro-inflammatory mediators expression by odontoblast-like cells, after in-office tooth whitening. Dental cavities prepared in bovine enamel/dentin discs were adhesively restored and subjected or not to hydrolytic degradation (HD). A whitening gel with 35% H2O2 (WG) was applied for 45 min onto restored and non-restored specimens adapted to artificial pulp chambers giving rise to the groups: SD- intact discs (control); SD/HP- whitened intact discs; RT/HP- restored and whitened discs; and RT/HD/HP- restored and whitened discs subjected to HD. The extracts (culture medium + WG components diffused through enamel/dentin/restoration interface) were collected and applied to odontoblast-like MDPC-23 cells. The study evaluated the amount of H2O2 in the extracts, as well as the cell viability (CV), cell morphology (CM), and gene expression of inflammatory mediators (TNF-α and COX-2) by the pulp cells exposed to the extracts (ANOVA and Tukey tests; 5% significance). All whitened groups presented lower CV than SD (control; p<0.05). The highest CV reduction and gene expression of TNF-α and COX-2 was observed in the RT/HD/HP group in comparison with SD/HP and RT/HP (control; p<0.05). CM alterations occurred in all whitened groups. The intensity of these cell side effects was directly related with the amount of H2O2 in the extracts. We concluded that adhesive restoration of dental cavity increases the H2O2 diffusion after in-office whitening, enhancing the indirect toxicity of this therapy and trigger pro-inflammatory overexpression by MDPC-23 cells.

Resumen Introducción: La ecocardiografía bidimensional es la técnica más efectiva para el diagnóstico del derrame pericárdico, gracias a sus altas sensibilidad y especificidad. Objetivo: Analizar la superioridad del método de suma de discos comparado con el método bidimensional en la estimación del derrame pericárdico por medio de ecocardiografía, tomando como referencia el volumen de líquido pericárdico extraído por pericardiocentesis o cirugía abierta. Método: Estudio retrospectivo de seguimiento de una cohorte basado en registros médicos y archivos de ecocardiografía. Se empleó un diseño pareado en el que cada imagen fue leída por el método bidimensional y por el método de suma de discos. Se incluyeron derrames pericárdicos graves, definidos clínicamente o por parámetros ecocardiográficos, que requirieran drenaje. El desempeño de los métodos de estimación bidimensional y de suma de discos, tomando como referencia la extracción por intervención, se cuantificó mediante áreas bajo la curva operador-receptor (auROC). Resultados: Se analizaron 40 registros, tomando como referencia el volumen obtenido por extracción; con un auROC de 0.81 (intervalo de confianza del 95% [IC95%]: 0.73-0.89), el desempeño diagnóstico del método de suma de discos fue significativamente mayor (p = 0.0335) que el del método bidimensional (auROC: 0.73; IC95%: 0.63-0.83). La estimación realizada por el método de suma de discos subestimó en promedio 51.3 ml (IC95%: −156.2-53.5). Conclusiones: En pacientes con derrame pericárdico e indicación de drenaje o taponamiento cardíaco, el método de suma de discos es superior en comparación con el método bidimensional en el estudio ecocardiográfico para la estimación cuantitativa del derrame pericárdico, ya que discrimina mejor respecto al método bidimensional.

Abstract Introduction: Two-dimensional echocardiography is the most effective technique for diagnosing pericardial effusion due to its high sensitivity and specificity. Objective: The superiority of the method of disks was compared with the bidimensional method in the estimation of pericardial effusion by echocardiography, taking as reference the volume of pericardial fluid removed by pericardiocentesis or open surgery. Method: Retrospective follow-up study of a cohort, based on medical records and echocardiography files. A paired design was used, each image was read by the bidimensional method and by the method of disks. Severe pericardial effusions defined clinically or by echocardiographic parameters, that required drainage were included. The performance of the bidimensional and disks estimation methods, taking the volume removed as a reference, was quantified using areas under the receiver operating characteristic curve (auROC). Results: 40 records were analyzed, taking as a reference the volume obtained by extraction, with an auROC of 0.81 (95% CI: 0.73-0.89) the diagnostic performance of the disks method was significantly higher (p = 0.0335) than the bidimensional method (auROC 0.73, 95% CI: 0.63-0.83). The estimate made by the disks method underestimated an average of 51.3 ml (95% CI: -156.2-53.5). Conclusions: In patients with pericardial effusion with indication of cardiac drainage or tamponade, the disks method is superior in comparison with the bidimensional method in the echocardiographic study of the quantitative estimation of pericardial effusion, discriminating better than the bidimensional method.

Resumo Neste estudo, apresentamos um relato de pesquisa acerca de uma psicologia da diferença nas relações raciais, a fim de cartografar processos de subjetivação das relações raciais na formação da(o) psicóloga(o) e sua interface com a atuação profissional. Como métodos de pesquisa, utilizamos a cartografia, a participação observante, um círculo de cultura e duas rodas de conversa para produzir narrativas, relato e escrita de si em diário cartográfico. Para discussão e análise, realizamos um exercício ético-estético-poético e político, operando com ferramentas-conceitos da esquizoanálise e da epistemologia da decolonização. Como política dessa invenção, considera-se que: a) o pesquisador devém analisador/testemunha do lugar de fala das mulheres negras que compõem a cartografia a partir de sua representatividade; b) a presença de um número reduzido de negras(os) nos cursos da área da saúde é efeito da colonização da academia; c) a implicação ético-política da(o) psicóloga(o) emerge como dispositivo de enfrentamento ao racismo institucional; e que d) um movimento estudantil menor, ao devir comum minoritário, rompe com o instituído e instaura, de modo criativo, discussões que suscitam o debate em torno da psicologia nas relações raciais e de situações-problema que emergem do dispositivo interseccionalidade.

Abstract This study presents a research report about a psychology of the difference in race relations, aiming to map the subjectivation processes of race relations in the psychologist’s training and their interface with the professional performance. We used cartography, observant participation, a culture circle, and two conversation circles for narrative production, self-reporting and writing in a cartographic diary as a research method. For the discussion and analysis, we conducted an ethical-aesthetic-poetic and political exercise, operating tools-concepts of schizoanalysis and the epistemology of decolonization. As a policy of this invention: a) the researcher becomes an analyzer/witness of the place of speech of black women who make up cartography from their representativeness; b) the presence of a small number of black women in health courses is an effect of the academy colonization; c) the ethical-political implication of the psychologist emerges as a device to confront institutional racism; and d) a smaller student movement becoming the common minority breaks with the instituted, creatively instituting discussions that open the debate about psychology in race relations and problem situations that emerge from the intersectionality device.

Resumen En este estudio, presentamos un informe de investigación sobre la psicología de la diferencia en las relaciones raciales, con el objetivo de mapear los procesos de subjetivación de las relaciones raciales en la formación del/la psicólogo/a y su interfaz con la práctica profesional. Como método de investigación, utilizamos la cartografía, la participación observadora, el círculo cultural y círculos de conversación para producir narrativa, relatos y escritura de sí en un diario cartográfico. Para la discusión y análisis, realizamos un ejercicio ético-estético-poético y político, operando herramientas y conceptos del esquizoanálisis y la epistemología de la decolonización. Como política de esta invención se considera que: a) el investigador se convierte en un analizador/testigo del lugar de habla de las mujeres negras que componen la cartografía desde su representatividad; b) la presencia de un pequeño número de negras/os en cursos de salud es resultado de la colonización de la academia; c) la implicación ético-política del/la psicólogo/a surge como un dispositivo para enfrentar el racismo institucional; y que d) un movimiento estudiantil más pequeño con el devenir común de la minoría rompe con lo establecido, instituyendo creativamente discusiones sobre la psicología en las relaciones raciales y las situaciones problemáticas que surgen del dispositivo de interseccionalidad.
