ABSTRACT The objective of this study was to evaluate the agronomic performance and select biomass sorghum genotypes for growing in different regions of Brazil based on adaptability and stability analysis using the GGE biplot method. The 25 genotypes evaluated were from trials of value for cultivation and use (VCU) of biomass sorghum of the Brazilian Agricultural Research Corporation (Embrapa Maize and Sorghum) Breeding Program, conducted in eight locations across Brazil (Sobral, CE; Jaguariúna and Narandiba, SP; Nova Porteirinha and Sete Lagoas, MG; Planaltina, DF; Vilhena, RO; and Terra Rica, PR) during the 2021-2022 crop season. A randomized block experimental design with three replications was used. The following traits of were subjected to joint analysis of variance: plant height, flowering, and fresh and dry matter yields. The confirmation of genotype-by-environment interaction (G×E) was followed by adaptability and stability analysis using the GGE biplot method for all traits. The adjusted means were used to obtain the mean clustering using the Scott-Knott test (p < 0.05). Biomass sorghum genotypes showed a longer growth cycle, taller plants, and higher biomass yield than forage sorghum genotypes. The experimental sorghum hybrids 202129B014 and 202129B016 and the commercial hybrid BRS 716 can be recommended for fresh and dry matter production in all tested environments due to their high adaptability and stability. 2 VCU (VCU Embrapa Sorghum Program Sobral, Sobral (Sobral CE Narandiba SP Lagoas MG Planaltina DF Vilhena RO Rica PR 20212022 2021 2022 2021-202 season variance height flowering yields genotypebyenvironment genotype environment G×E GE G E (G×E ScottKnott Scott Knott p 0.05. 005 0.05 . 0 05 0.05) cycle plants B 202129B01 71 2021202 202 2021-20 00 0.0 202129B0 7 202120 20 2021-2 0. 202129B 20212 2021-

Resumen Introducción : El objetivo de este estudio fue evaluar los efectos adversos y la respuesta inmune de anticuer pos IgG anti S1 SAEA-CoV-2 en el personal de Salud del Hospital del Milagro de la ciudad de Salta, posterior a recibir dos dosis de vacuna COVID-19. Métodos : Se realizó un estudio prospectivo de co horte desde marzo de 2021 hasta abril 2022. Se reco pilaron datos demográficos, clínicos, eventos adversos supuestamente atribuidos a la vacunación (ESAVI) y se tomaron dos muestras de sangre para medir los niveles de anticuerpos. Resultados : Participaron 408 voluntarios, 401 (98%) fueron vacunados con Sputnik- V. La edad promedio fue de 45.5 años con predominio del sexo femenino (71%). Los ESAVI fueron reportados en 188 (46.1%) y 121 (29.7%) luego de la primera y segunda dosis respectivamente (p<0.001). Estos eventos fueron mayormente de carácter leve y transitorios, más frecuentes luego de la primera dosis. El primer dosaje de anticuerpos fue positivo en 99% con una media de títulos de 9.7 (SD 3.7). El segundo dosaje fue positivo en 88% con una media de títulos de 6.4 (SD 4.4). Los participantes con antecedentes de infección y dosajes previos positivos mostraron títulos significativamente más altos de anticuerpos (p<0.001). Conclusión : Los ESAVI reportados fueron mayorita riamente leves y transitorios. La vacunación masiva y la administración de la dosis recomendada son esenciales para lograr una inmunidad colectiva efectiva. La mayoría de los trabajadores de la salud vacunados desarrollaron anticuerpos y aquellos que cursaron la enfermedad previa a la vacunación presentaron títulos significativos más elevados de anticuerpos.

Abstract Introduction : The aim of this study was to evaluate the adverse effects and immune response associated with IgG anti S1 SAEA-CoV-2 antibodies among health care workers at Señor del Milagro Hospital in Salta city, after receiving two doses of COVID-19 vaccine. Methods : A prospective cohort study was carried out from March 2021 to April 2022. Demographic, clinical data, adverse events supposedly attributed to vaccina tion (AEFIs) were collected and two samples were taken to measure serum antibody levels. Results : 408 volunteers participated, 401 (98%) were vaccinated with Sputnik-V. The average age was 45.5 years with a predominance of the female sex (71%). AEFIs were reported in 188 (46.1%) and 121 (29.7%) after the first and second doses respectively (p<0.001). These events were mostly mild and transient, more frequent after the first dose. The first antibody test was positive in 99% with a mean titer of 9.7 (SD 3.7). The second dosage was positive in 88% with a mean titer of 6.4 (SD 4.4). Participants with a history of infection and previous positive testing showed significantly higher antibody titers (p<0.001). Conclusion : The AEFIs reported were mostly mild and transient. Mass vaccination and administration of the recommended dose are essential to achieve effective herd immunity. The majority of vaccinated healthcare workers developed antibodies and those who had the disease prior to vaccination had significant antibody titers.

Resumo Informações sobre a ocorrência de espécies são fundamentais para a compreensão da distribuição da biodiversidade. Porém, a biodiversidade do oeste do Estado do Paraná tem sido historicamente menos estudada, especialmente a de anfíbios e répteis. Por esse motivo, apresentamos a primeira lista de espécies de répteis do oeste do Estado do Paraná e ampliamos a lista atual de anuros para o município de Foz do Iguaçu. A lista de espécies foi baseada em um estudo sistemático de campo realizado em uma área de conservação dentro da Usina Hidrelétrica Itaipu Binacional. Integramos a lista de espécies com observações de espécies anteriores disponíveis na literatura para o mesmo local onde nossa amostragem foi realizada. Um total de 41 espécies são apresentadas. Todas as espécies de anuros encontradas foram registradas em campo; entretanto, das 22 espécies de répteis registradas, três foram registros obtidos antes deste estudo. Todas as espécies foram classificadas como “Pouco Preocupante” e/ou tinham status de “População Estável” de acordo com a IUCN. A suficiência amostral foi alcançada para anuros, mas não para répteis, provavelmente devido à baixa abundância de diversas espécies de serpentes. A espécie de anuro mais abundante foi Dendropsophus nanus, da família Hylidae, enquanto Leptodactylus plaumanni e Scinax squalirostris foram representados por apenas um indivíduo cada. O lagarto Salvator merianae foi o réptil mais abundante, e sete espécies foram representadas por um indivíduo cada. O método de amostragem mais bem sucedido para anuros adultos foi a busca ativa em corpos d’água, enquanto a maioria das espécies de répteis foi observada por encontros acidentais e não através de um método de amostragem sistematizado. Descobrimos que a composição da herpetofauna do Refúgio Biológico Bela Vista foi semelhante à de outras comunidades do estado do Paraná que também ocorrem dentro da Floresta Estacional Semidecidual. Por fim, como informações adicionais à lista de espécies, oferecemos chaves de identificação das espécies e discutimos sobre a importância da área de Itaipu para abrigar a diversidade de anuros e répteis da região.

Abstract Information regarding species occurrence is fundamental to understanding biodiversity distribution. However, the biodiversity from the west of the state of Paraná has been historically less studied, especially amphibians and reptiles. For this reason, we present the first reptile list of species from the west of the state of Paraná and extend the current list of anurans for the municipality of Foz do Iguaçu. The species list was based on a systematic field study conducted at Refúgio Biológico Bela Vista (RBV) a conservation area within the Hydroelectric Power Itaipu Binacional. We integrated the species list with previous species observations available in the literature for the same place where our sampling was conducted. A total of 41 species of amphibians and reptiles are presented. All amphibians species found were recorded in the field; however, from the 22 species of reptiles recorded, three were historical records obtained before this study. Species were all classified as Least Concern and/or had stable populational status according to the IUCN. Sampling sufficiency was achieved for anurans but not for reptiles, probably due to low abundance of several snake species. The most abundant species of anuran was Dendropsophus nanus, from the Hylidae family, whereas Leptodactylus plaumanni and Scinax squalirostris were represented by only one individual each. The lizard Salvator merianae was the most abundant reptile, and seven species were represented by only one individual each. The most successful sampling method for adult anurans was active search in water bodies whereas most of reptile species were observed by accidental encounters and not through a systematic sampling method. We found that herpetofauna composition from RBV was similar to other communities from Paraná state that also occur within the Semideciduous Seasonal Forest. Finally, as additional information to the species list, we offer species identification keys and discuss the importance of Refúgio Biológico Bela Vista to harbor the anuran and reptile diversity of the region. distribution However studied reason Iguaçu (RBV Binacional 4 presented however 2 andor or IUCN nanus family each Forest Finally region

Abstract The Shortnose Guitarfish, Zapteryx brevirostris , is endemic to the Southwest Atlantic and its geographic range is commonly reported from Southeastern Brazil to Northern Argentina. However, range limits are imprecise or inconsistent in some cases. These inconsistencies were addressed in this study based on 1,363 specimens collected since 1865. These records were obtained from scientific collections, a systematic review of literature, and an on-board observation database. According to the data collected in this study, the known northernmost distributional limit of the species lies at the mouth of the Doce River, Northern Espírito Santo State, in Southeastern Brazil (19°S). As for the other extreme of its range, the known southernmost distribution limit refers to the Falkland Islands (Malvinas) (53°S). This represents more than 2,000 km of coastline geographic range extension — in comparison to the previous known southernmost range limit for this species. The geographical range of Z. brevirostris seems to follow biogeographic patterns operating at an ecosystem level in which biotic (especially in the north) and abiotic factors (especially in the south) play a role in imposing limits to its distribution range.

Abstract Hurtado Almonacid, J.G., Páez Herrera, J., Abusleme Allimant, R. Olate Gómez, F., Follegati Shore, S., Briones Oyanedel, V. & Mallea Díaz, V. (2023). Level of motor coordination in children participating in the integral sports schools program of chile's sports ministry. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 21(1), 1-16. In recent years, it has been detected that generally low motor coordination results in low participation in free play situations, organized and free sports activities. In turn, a better motor mastery is consistent with a low level of sedentary lifestyle. Therefore, the objective of this article is to compare the level of general motor coordination in children that participate in the Sports Initiation component of the ''Integral Sports Schools'' (EDI) program of Chile's Sports Ministry (since 2019, ''Growing in Movement''), according to the regions they come from. Concerning the sample, the assessment covered 341 boys and girls from eight different regions in the country (Antofagasta, Coquimbo, Valparaíso, O'Higgins, Metropolitan Region, Bío-Bío, Araucanía and Los Lagos), in ages ranging from 6 to 11. The information was gathered through the 3JS instrument, made up of seven tasks (3 in locomotion and 4 in object control). The results showed that boys have a better performance than girls in terms of general motor coordination. When the test data were grouped according to the type of coordination, boys are also above girls in terms of locomotion and object control. Boys and girls from the Los Lagos region performed better in six of seven tests. In conclusion, boys outperform girls in the tests of motor coordination and object control, as well as in the scores of general motor coordination.

Nível de coordenação motora das crianças que participam do programa escolas esportivas integrais do ministério do esporte do Chile. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 21(1), 1-16. Nos últimos anos, identificou-se que a baixa coordenação motora geral tem um impacto na baixa participação em atividades de jogos livres, atividades esportistas organizadas e livres. Por sua vez, uma melhor dominância motora está relacionada com um baixo nível de sedentarismo. Portanto, o objetivo deste artigo foi comparar o nível de coordenação motora geral das crianças participantes do componente de Iniciação Esportiva do programa "Escolas Esportivas Integrais" (EEI) do Ministério do Esporte do Chile ("Crescendo em Movimento" desde 2019), segundo a região de origem. Em relação à amostra, foram avaliadas 341 crianças de oito regiões do país (Antofagasta, Coquimbo, Valparaíso, O'Higgins, Metropolitana, Bío-Bío, Araucanía e Los Lagos) com idades entre 6 e 11 anos. Para a coleta de informações, foi utilizado o instrumento 3JS, composto por sete tarefas (3 de locomoção e 4 de controle de objetos). Os resultados mostraram que os meninos têm melhor desempenho do que as meninas na coordenação motora geral. Ao agrupar os testes de acordo com o tipo de coordenação, eles também superam as meninas em locomoção e controle de objetos. As crianças da região de Los Lagos tiveram melhor desempenho em seis dos sete testes. Conclui-se que os meninos superam as meninas nos testes de coordenação locomotora e controle de objetos, bem como nos escores gerais de coordenação motora.

RESUMO A salinidade causada pelo excesso de sais na solução do solo é um dos estresses ambientais mais limitantes na agricultura no mundo. Nesse cenário, dentre as estratégias para favorecer a expressão do potencial genético das plantas, destaca-se o uso de bioestimulantes. Objetivou-se avaliar a influência de um bioestimulante à base de extrato de algas marinhas no crescimento, produção de forragem, trocas gasosas e acúmulo de íons sódio e potássio em capim-pangolão Digitaria pentzii, submetido a condições de estresse salino. O experimento foi conduzido de março a julho de 2019, em delineamento de blocos casualizados, em esquema fatorial 2 × 3, com duas concentrações do bioestimulante (0 e 8 mL L-1) e três condutividades elétricas da água de irrigação (0,03; 2 e 4 dS m-1), com quatro repetições. O acúmulo de 50 µmol g-1 de sódio nas folhas correspondeu a uma redução de 0,3 g de matéria seca na produção de lâminas foliares por vaso. O bioestimulante não influenciou as características estruturais do capim-pangolão, acúmulo de fitomassa e condutância estomática, independentemente da salinidade. No nível de 4 dS m-1 na água de irrigação, a toxicidade do estresse iônico devido ao acúmulo de sais na parte aérea do capim-pangolão é mais severa. Esta é a primeira evidência da tolerância “moderada” à salinidade do capim-pangolão em regiões semiáridas.

ABSTRACT Salinity caused by excess salts in soil solutions is one of the most limiting environmental stresses in agriculture worldwide. In this scenario, among strategies that favor the expression of the genetic potential of plants, the use of biostimulants stands out. The objective of this study was to evaluate the influence of a seaweed-based biostimulant on growth, forage production, gas exchange, and accumulation of sodium and potassium ions in pangolão grass (Digitaria pentzii) under saline stress. The experiment was conducted from March to July 2019 using a randomized block design, in a 2 × 3 factorial scheme with two concentrations of biostimulant (0 and 8 mL L-1) and three electrical conductivities of irrigation water (0.03, 2 and 4 dS m-1), with four replicates. The accumulation of 50 µmol g-1 of sodium in leaves corresponded to a reduction of 0.3 g of dry matter in the leaf blade production per plot. The biostimulant did not influence the structural characteristics, phytomass accumulation, or stomatal conductance of the pangolão grass, regardless of salinity. At the level of 4 dS m-1 in irrigation water, the ionic stress toxicity due to the accumulation of salts in the aerial part of pangolão grass was more severe. This is the first evidence of the “moderate” salinity tolerance of pangolão grass in semi-arid regions.

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.

Abstract This study aimed to characterize the spatial distribution and composition of living Benthic Foraminifera (BF) and to comprehend how environmental conditions (e.g., organic matter) can affect communities of these protozoa in the northern and southern sectors of the Santos Basin (SB), in the continental slope and São Paulo Plateau. In this context, 23 stations (65 samples including replicates at each station) were collected between 400 and 2,400 m water depth. Multivariate analyses revealed that the ecological structure of the community changes mainly along the bathymetric gradients. Stations located between 400 and 700 m, both in northern and southern sectors, are characterized by the presence of indicator species of high intensity of currents, such as Globocassidulina subglobosa and Trifarina bradyi. These stations are also mainly marked by the occurrence of Epistominella exigua, a phytodetritivore species. The stations at 1,000 and 1,300 m depth, in both sectors, are characterized by high accumulation of organic matter in the sediments, which favors the development of agglutinated foraminifera species, such as those of the genus Reophax. Finally, the lower slope and the São Paulo Plateau, in both sectors, are oligotrophic regions, with pulses of labile organic carbon, probably low current velocities and the presence of Alabaminella weddellensis. The quantity and quality of food, which are closely related to hydro-sedimentary dynamics and bentho-pelagic coupling in the slope and São Paulo Plateau, are the main factors that influence the distribution of living BF assemblages in the SB.

ABSTRACT The COS method was introduced in Fang & Oosterlee (2008) and then was applied to pricing a variety of stock options for continuous random variables. This paper adapts the Fourier-cosine series (COS) method to recover discrete probability mass functions. We approximate mixture and compound probability distributions with cosine series. Enormous precision and computational speed are the qualities of the function estimates here obtained. We also develop the pricing framework to trade derivatives subject to discrete random variables. We apply the method to calculate, for the first time, the price of an interest rate derivative of recent vintage introduced in the Brazilian financial market. Parameter calibration confirms the quality of the model. 2008 (2008 variables Fouriercosine Fourier (COS functions obtained calculate time market model 200 (200 20 (20 2 (2 (

RESUMEN Introducción: La infección relacionada con catéter venoso central (CVC) es la complicación más frecuente y grave en los pacientes en hemodiálisis, asociada a una elevada mortalidad y morbilidad. En España, se ha publicado una incidencia de bacteriemia de 0.9 a 2 episodios por catéter y año. Diversas variables se han relacionado con la tasa de bacteriemia asociada a CVC, tales como disfunciones del catéter, la formación y experiencia del personal de enfermería, el número de sesiones de hemodiálisis y la duración de las mismas. El objetivo del presente estudio es analizar la influencia de las variables citadas en la aparición de bacteriemias, en pacientes portadores de catéteres en una unidad de hemodiálisis de un hospital de tercer nivel en España. Material y métodos: Estudio analítico, observacional y retrospectivo en el que se obtuvieron los datos relativos a la formación recibida y experiencia del personal de enfermería, el número y duración de sesiones de hemodiálisis por paciente y disfunciones de CVC. Se contabilizaron las bacteriemias acontecidas en un año, a través de la base de datos de la unidad, y se analizó la posible relación de tales variables en la tasa de bacteriemia. Resultados: Sobre un total de 41 catéteres tunelizados en 35 pacientes, observados durante 365 días, se obtuvo una tasa de incidencia de 1.45/1000 días de catéter, no habiendo encontrada relación estadísticamente significativa con la formación del personal de enfermería (p=0.330), experiencia (p=0.668), número de disfunciones y manipulaciones de catéter (p=0.718; p=0.118). Se objetivó relación inversa con el número y duración de sesiones (p=0.02). Conclusiones: Es preciso seguir analizando la relación entre las variables mencionadas y la tasa de bacteriemias. Abordarlo desde un punto de vista multicéntrico o aumentar el tiempo de observación de forma prospectiva pueden ser aspectos a tener en cuenta para determinar las variables que parecen tener una relación directa con la infección de CVC, que en otros contextos se ha llegado a evidenciar.

ABSTRACT Introduction: Central venous catheter (CVC)-related infection is the most frequent and serious complication in hemodialysis patients, associated with high mortality and morbidity. In Spain, an incidence of bacteremia of 0.9 to 2 episodes per catheter and year has been published. Variables have been related to the rate of bacteremia associated with CVC, such as catheter malfunctions, the training and experience of the nursing, the number of hemodialysis sessions and their duration. The objective of the present study is to analyze the influence of the aforementioned variables on the appearance of bacteremia in patients with catheters in a hemodialysis unit of a tertiary care hospital in Spain. Methods: Analytical, observational, and retrospective study in which data on the training received and experience of the nursing staff, the number and duration of hemodialysis sessions per patient and CVC dysfunctions were obtained. The bacteremia’s that occurred in a year were counted, through the unit’s database, and the possible relationship of such variables in the rate of bacteremia was analyzed. Results: On a total of 41 tunneled catheters in 35 patients, observed for 365 days, an incidence rate of 1.45/1000 catheter days was obtained, not having found a statistically significant relationship with the training of nursing staff (p = 0.330), experience (p=0.668), number of dysfunctions and manipulations of catheter (p=0.718; p=0.118). An inverse relationship was observed with the number and duration of sessions (p=0.02). Conclusions: It is necessary to continue analyzing the relationship between the mentioned variables and the rate of bacteremia. Approaching it from a multicenter point of view or increasing the observation time prospectively may be aspects to consider to determine the variables that seem to have a direct relationship with CVC infection, which has been shown in other contexts.

We aimed to estimate the prevalence and factors associated with parents’ non-intention to vaccinate their children and adolescents against COVID-19 in Colombia and Peru. We performed a secondary analysis using a database generated by the University of Maryland and Facebook (Facebook, Inc). We included adult (18 and over) Facebook users residing in LAC who responded to the survey between May 20, and November 5, 2021. We included sociodemographic characteristics, comorbidities, mental health, economic and food insecurity, compliance with mitigation strategies against COVID-19, and practices related to vaccination against this disease. We estimated crude (cPR) and adjusted (aPR) prevalence ratios with their respective 95%CI. We analyzed a sample of 44,678 adults from Colombia and 24,302 from Peru. The prevalence of parents' non-intention to vaccinate their children and adolescents against COVID-19 was 7.41% (n=3,274) for Colombia and 6.64% (n=1,464) for Peru. In Colombia, age above 35 years old, compliance with physical distancing, use of masks, having economic insecurity, anxiety symptoms, having a chronic condition or more comorbidities, and being vaccinated were associated with a lower prevalence of non-intention to vaccinate children and adolescents against COVID-19. In Peru, gender, compliance with physical distancing, use of masks, having economic insecurity, anxiety symptoms, having a chronic condition or more comorbidities, having had COVID-19, and being vaccinated were associated with a higher probability of vaccinating children against COVID-19. Living in a town, a village, or a rural area was associated with a higher prevalence of non-intention to vaccinate children and adolescents against COVID-19. About 9 out of 10 parents in Colombia and Peru intend to vaccinate their children and adolescents against COVID-19. This intention is associated with some factors which are similar between the two countries, as well as other factors and variations among the different regions of each country.

Resumo Os aditivos aromatizantes têm grande importância tecnológica para a indústria de alimentos. Contudo, poucas são as informações quanto as propriedades toxicológicas desses microingredientes, especialmente, em nível celular. No presente estudo avaliou-se, sobre as células meristemáticas de raízes de Allium cepa L., a toxicidade de um aditivo sintético líquido de aroma e sabor de chocolate, fabricado e amplamente comercializado em todo Brasil, e exportado para outros países da América do Sul. As concentrações de aromatizante avaliadas foram 100,00; 50,00; 25,00; 1,00; 0,50 e 0,25 µL/L, onde a maior concentração estabelecida foi cem vezes menor que a sugerida comercialmente para uso. Com base na interpretação dos resultados, a concentração 100 µL/L reduziu substancialmente a divisão celular dos meristemas nas 24 e 48 horas de exposição. As concentrações 100,00 a 0,50 µL/L demonstraram número significativo de prófases em detrimento as outras fases da divisão celular, indicando ação aneugênica, e induziram número significativo de alterações celulares, com ênfase a micronúcleos, broto nucleares e quebras cromossômicas. Nas condições de análises estabelecidas, com exceção a concentração 0,25 µL/L, o aromatizante de chocolate causou citotoxicidade, genotoxicidade e mutagenicidade aos meristemas radiculares.

Abstract Flavoring additives are of great technological importance for the food industry. However, there is little information regarding the toxicological properties of these micro-ingredients, especially at the cellular level. The present study used meristematic root cells of Allium cepa L. to evaluate the toxicity of a liquid, aroma and flavor synthetic chocolate additive, manufactured and widely marketed throughout Brazil and exported to other countries in South America. The flavoring concentrations evaluated were 100.00; 50.00; 25.00; 1.00; 0.50 and 0.25 µL/L, where the highest concentration established was one-hundred times lower than that commercially suggested for use. The concentration 100 µL/L substantially reduced cell division of meristems within 24- and 48-hours exposure. Concentrations from 100.00 to 0.50 µL/L resulted in a significant number of prophases to the detriment of the other phases of cell division, indicating an aneugenic activity, and induced a significant number of cellular changes, with emphasis on micronuclei, nuclear buds and chromosomal breaks. Under the established analysis conditions, with the exception of concentration 0.25 µL/L, the flavoring of chocolate caused cytotoxicity, genotoxicity and mutagenicity to root meristems.

ABSTRACT Objectives: To estimate the prevalence and factors associated with the intention to be vaccinated (ITV) against COVID-19 in Peru. Materials and methods: Analytical cross-sectional study using the survey conducted by the University of Maryland, USA, on Facebook. The dependent variable is the ITV. Crude and adjusted prevalence ratios (PR) were calculated, with their 95% confidence intervals (95% CI) using generalized linear models of the Poisson family, in order to evaluate the association of sociodemographic variables, compliance with community mitigation strategies, symptoms of COVID-19, mental health and acceptance of vaccination before the recommendation (AVR) by various actors and health authorities, with the ITV. Results: Data from 17,162 adults were analyzed. The overall prevalence of the ITV was 74.9%. A lower prevalence of the ITV was associated with the female sex (PR=0.95; 95% CI: 0.94-0.97), living in a town (PR=0.95; 95% CI: 0.91-0.99) or village or other rural area (PR=0.90; 95% CI: 0.86-0.93) and the AVR of politicians (PR=0.89; 95% CI: 0.87-0.92). Conversely, having COVID-19 symptoms (PR=1.06; 95% CI: 1.03-1.09), economic insecurity (PR=1.04; 95% CI: 1.01-1.06), fears of becoming seriously ill or that a family member becomes seriously ill from COVID-19 (PR=1.49; 95% CI: 1.36-1.64) and the AVR of family and friends (PR=1.10; 95% CI: 1.08-1.12), healthcare workers (PR=1.29; 95% CI: 1.26-1.32), World Health Organization (PR=1.34; 95% CI: 1.29-1.40) and government officials (PR=1.18; 95% CI: 1.15-1.22) was associated with a higher prevalence of the ITV. Conclusions: Three-quarters of the respondents had the ITV. There are potentially modifiable factors that could improve vaccine acceptance.

RESUMEN Objetivos: Estimar la prevalencia y los factores asociados a la intención de vacunación (IDV) contra la COVID-19 en el Perú. Materiales y métodos: Estudio transversal analítico utilizando una encuesta realizada por la Universidad de Maryland, EUA, en Facebook. La variable dependiente fue la IDV. Se calcularon razones de prevalencia (RP) crudas y ajustadas, con sus intervalos de confianza al 95% (IC95%), mediante modelos lineales generalizados de la familia Poisson para evaluar la asociación de variables sociodemográficas, el cumplimiento de estrategias comunitarias de mitigación, los síntomas de la COVID-19, la salud mental y la aceptación de la vacunación ante la recomendación (AVR) por diversos actores y autoridades sanitarias. Resultados: Se analizaron los datos de 17 162 adultos. La prevalencia general de la IDV fue del 74,9%. Se asociaron a una menor prevalencia de la IDV ser de sexo femenino (RP=0,95; IC95%:0,94-0,97), vivir en un pueblo (RP=0,95; IC95%:0,91-0,99) o en una aldea u otra área rural (RP=0,90; IC95%:0,86-0,93) y la AVR de políticos (RP=0,89; IC95%: 0,87-0,92). Contrariamente, tener síntomas de COVID-19 (RP=1,06; IC95%:1,03-1,09), inseguridad económica (RP=1,04; IC95%: 1,01-1,06), miedo a enfermar o que un familiar enferme de COVID-19 (RP=1,49; IC95%: 1,36-1,64) y la AVR de familiares y amigos (RP=1,10; IC95%: 1,08-1,12), trabajadores de la salud (RP=1,29; IC95%: 1,26-1,32), la Organización Mundial de la Salud (RP=1,34; IC95%: 1,29-1,40) y funcionarios del gobierno (RP=1,18; IC95%: 1,15-1,22) se asociaron con mayor prevalencia de IDV. Conclusiones: Tres cuartas partes de los encuestados manifiestan IDV. Existen factores potencialmente modificables que podrían mejorar la aceptación de la vacuna.

Abstract Individuals with malignancies and COVID-19 have a lower survival compared with the general population. However, the information about the impact of COVID-19 on the whole hematological population is scarce. We aimed to describe the 30th day overall survival (OS) after COVID-19 infection in pa tients with a hematological disease in Argentina. A completely anonymous survey from the Argentine Society of Hematology was delivered to all the hematologists in Argentina; it started in April 2020. A cut-off to analyze the data was performed in December 2020 and, finally, 419 patients were reported and suitable for the analysis (average age: 58 years, 90% with malignant diseases). After the COVID-19 diagnosis, the 30-day OS for the whole population was 80.2%. From the entire group (419), 101 (24.1%) individuals required intensive care unit admission, where the 30-day OS was 46.6%. Among allogeneic stem cell transplant recipients, the 30-day OS was 70.3%. Factors associated with a low OS were two or more comorbidities, an active hematological disease and history of chemotherapy. In individuals with the three factors, the 30-day OS was 49.6% while the 30-day OS in those without those factors was 100%. Patients with hematological diseases have a higher mortality than the general population. This group represents a challenge and requires careful decision-making of the treatment in order not to compromise the chances of cure.

Resumen El presente estudio tuvo por objetivo primario conocer la mortalidad de pacientes con enfermedad hematológica que presentaron infección por COVID-19 en Argentina. Para ello se difundió una encuesta desde la Sociedad Argentina de Hematología (SAH) entre los hematológos para informar sobre los pacientes con enfermedades hematológicas y diagnóstico de infección por SARS- CoV-2, entre el 19/4/2020, y el 7/12/2020. Se incluyeron individuos de todas las edades con diagnóstico de enfermedad hematológica benigna o maligna e infección por SARS-CoV-2 confirmada por técnica de RT-PCR. Se analizaron 419 pacientes (mediana 58 años; 90% enfermedades malignas). La supervivencia al día 30 fue de 80.2%. La supervivencia fue menor en aquellos que requirieron internación (74.2%), cuidados intensivos (46.6%) y asistencia respiratoria mecánica (36.8%). Entre los trasplantados alogénicos la supervivencia fue 70.3%. Los factores vinculados a la supervivencia global fueron las comorbilidades, el estado de la enfermedad al momento de la infección y el antecedente de quimioterapia. Se pudo establecer un score en el que aquellos que tuvieron un puntaje de 4 alcanzaron una supervivencia del 49.6% al día 30, mientras que la de los pacientes con score 0 fue del 100% a 30 días. En comparación con la población general, los pacientes con enfermedades hematológicas presentan una mayor mortalidad vinculada al COVID-19, motivo por el cual es primordial definir pautas destinadas a disminuir la exposición de los mismos sin comprometer las posibilidades de beneficiarse del tratamiento de la enfermedad de base.
