ABSTRACT
Introducción: la yerba mate (Ilex paraguariensis) constituye un recurso alimentario autóctono, formando parte de la tradición y cultura alimentaria del Paraguay. Sin embargo, existen pocos estudios locales sobre los hábitos de consumo y preferencias por los paraguayos. Objetivo: describir los hábitos de consumo de la yerba mate (Ilex paraguariensis) en el Departamento Central en el 2022. Metodología: estudio descriptivo, transversal, con datos primarios, realizado en el Departamento Central de Paraguay. Muestreo no probabilístico en racimos. Instrumento de elaboración propia, diseñado como encuesta digital en la plataforma Google Form® (EE.UU.). Las variables fueron agrupadas en datos demográficos, relacionados al consumo de mate, tereré y cocido, procesados en Microsoft Excel® (EE.UU.) y EPI INFO® 7.0 (EE.UU.). Resultados: participaron 207 personas, la mayoría contaban entre 18 a 40 años, sexo femenino (83,22 %, 119), solteros, universitarios. El consumo más frecuente fue mate+ tereré+ cocido (43,96 %, 91) y tereré + cocido (14,01 %, 29). Todos los encuestados percibían más de dos salarios mínimos, y eran trabajadores de tiempo completo. El 81,64 % (169) consumían tereré, 69,08 % (143) mate, 80,23 % (138) cocido. El tipo de yerba más consumido fue la "compuesta con hierbas medicinales", con un promedio de 1,5 Litros diarios. Conclusión: las formas más consumidas son tereré, cocido y mate, el tipo de yerba es la compuesta con el agregado de hierbas medicinales. Se sugieren realizar estudios poblacionales más amplios sobre el consumo de bebidas a base de yerba mate en Paraguay, así como ampliar estudios sobre las posibles interacciones e inocuidad entre la yerba mate con hierbas medicinales.
Introduction: yerba mate (Ilex paraguariensis) constitutes a native food resource, forming part of the food tradition and culture of Paraguay. However, there are few local studies on the consumption habits and preferences of Paraguayans. Objective: to describe the consumption habits of yerba mate (Ilex paraguariensis) in the Departamento Central in 2022. Methodology: descriptive, cross-sectional study, with primary data, carried out in the Departamento Central of Paraguay. Non-probability cluster sampling. Self-developed instrument, designed as a digital survey on the Google Form® platform (USA). The variables were grouped into demographic data, related to the consumption of mate, tereré and cocido, processed in Microsoft Excel® (USA) and EPI INFO® 7.0 (USA). Results: people participated was 207, the majority were between 18 and 40 years old, female (83.22 %, 119), single, university students. The most frequent consumption was mate + tereré + cooked (43.96 %, 91) and tereré + cooked (14.01 %, 29). All respondents received more than two minimum wages, and were full-time workers. 81.64 % (169) consumed tereré, 69.08 % (143) consumed mate, 80.23 % (138) cooked. The most consumed type of herb was "composed with medicinal herbs", with an average of 1.5 Liters per day. Conclusion: the most consumed forms are tereré, cooked and mate, the type of yerba is the one composed with the addition of medicinal herbs. It is suggested to carry out larger population studies on the consumption of yerba mate-based drinks in Paraguay, as well as expand studies on the possible interactions and safety between yerba mate and medicinal herbs.
ABSTRACT
Introducción: Los estudios de preferencias de pareja han crecido ampliamente alrededor del mundo en los últimos años; no obstante, las pruebas psicológicas utilizadas en esta área no han sido adecuadamente adaptadas a contextos hispanohablantes. En esta investigación se adaptó al español una de las pruebas más frecuentemente usadas en el campo de la selección sexual humana: Ideal Partner and Relationship Scale (IPRS). Método: Se implementaron los siguientes procedimientos: (1) Traducción por pares, (2) Evaluación por expertos, (3) Aplicación inicial/validación (149 participantes), (4) Análisis de propiedades psicométricas, (5) Análisis confirmatorios con una muestra independiente (247 participantes). Resultados: Los análisis de las propiedades psicométricas de la prueba IPRS (español), indican que el instrumento conserva una estabilidad similar a la versión inglesa. En la estructura interna se conserva una solución factorial de cinco dimensiones de preferencia: atractivo físico, calidez y confianza, estatus y recursos, inteligencia y habilidades sociales. Además, los indicadores de confiabilidad demuestran una consistencia interna y estabilidad temporal sobresaliente. Por último, los patrones de preferencia de los participantes revelan similitudes con lo reportado en investigaciones transculturales semejantes. Conclusiones: Las sobresalientes propiedades referidas a la evidencia reportada en este estudio, llevan a considerar que la adaptación de la prueba IPRS al español fue exitosa, como resultado del seguimiento de protocolos estrictos de validación.
Introduction: Mate preference studies have been growing worldwide in recent years; however, the psychological tests used in this area have not been adequately adapted to Spanish-speaking contexts. This study aims to adapt to Spanish one of the most frequently used tests in human sexual selection: Ideal Partner and Relationship Scale (IPRS). Method: The adaptation included the following procedures: (1) Translation by peers; (2) Evaluation by experts; (3) Initial application / Validation (149 participants); (4) Analysis of psychometric properties; and (5) Confirmatory analysis from an independent sample (247 participants). Results: We proceeded to create the final version of the test in Spanish through the information collected. The analysis of the psychometric properties of the IPRS test indicates that the instrument retains stability and consistency similar to the original English version. This new version conserved the factorial structure, which includes five preference dimensions (physical attractiveness, warmth and trust, status and resources, intelligence, and social skills). Similarly, reliability indicators demonstrate good internal and temporal stability. Finally, the participant's preference patterns are equivalent to what has been reported in cross-cultural mate research. Conclusions: The good properties of the collected evidence led to the conclusion that the adaptation of the Spanish IPRS test was successful, as a result of strict validation protocols.
ABSTRACT
Abstract Background The traditional infusion of "yerba mate" is widely consumed in South America and exported to countries around the world. Although generally considered a "clear fluid", there is no data to date on the gastric emptying time of yerba mate and safe preoperative fasting intervals. The objective of this study was to evaluate the gastric emptying time of a standardized infusion of yerba mate using bedside ultrasound and compare it with the time confirm of hot and cold tea. Methods This was a prospective, randomized crossover experimental study. Thirty healthy volunteers were evaluated after 8 hours of fasting for both fluids and solids. Gastric antral area and gastric volume were evaluated at baseline and every 20 minutes after drinking 300 mL of randomly assigned infusion of "yerba mate", hot tea, or cold tea. Results The mean gastric emptying time was: 69.7 ± 22.1 min, 63.1 ± 14.5 min, and 64.3 ± 23.5 min for the mate, hot tea, and cold tea respectively. No significant differences were found in emptying time among the infusion groups (p-value = 0.043). When same time measures were compared, the only significant difference detected was between hot teas and mate infusion at 20 minutes (p-value = 0.012) Conclusion Yerba mate infusion has a similar gastric emptying time to that of tea. All subject's gastric volume returned to baseline values by 100 minutes. It is reasonable to recommend a similar fasting period of 2 hours for mate infusion prior to elective surgery.

Gestational Diabetes Mellitus is defined as a disease characterized by high levels of blood glucose, which is diagnosed for the first time during pregnancy. It can cause several maternal and fetal complications, often requiring early hospitalization and advanced care. The aim of thestudy was to characterize the epidemiological profile of pregnant women with gestational diabetes mellitus seen at a reference service. This is a descriptive, documentary, retrospective, quantitative study, carried out with pregnant women attended at the maternity hospital of the Hospital Regional do Sudoeste - PR in the city of Francisco Beltrão. The sample consisted of216 pregnant women, and data were collected from the patients' medical records. The study included all pregnant women who were attended and diagnosed with GDM in the period described, and who had at least one fasting glucose test or an oral glucose tolerance test for diagnostic confirmation. All pregnant women from the year 2019 and 2021 were excluded fromthe study. The sample had a higher percentage of GDM 90.7% according to race 69.9% werewhite, aged 15-35 years 68 , 5%, while 65.7% performed control with diet and 32.4% neededto use insulin and 51.9% of them were obese. This research had great results because it had an epidemiological profile of pregnant women diagnosed with Diabetes Mellitus, bringing benefitsand thus being able to identify gestational Diabetes mellitus early, aiming to avoid complications for the pregnant woman and the baby.

Yerba mate ( Ilex paraguariensis ) produces several secondary metabolites of interest to the phar maceutical industry, such as chlorogenic acids and methylxanthines. These compounds have been produced in vitro by callus culture from different species. However, for I. paraguariensis , no studies upon the production of these compounds in vitro have been p erformed to date. In this work, we show that the concentration of secondary metabolites from I. paraguariensis callus is possible and highly dependent on the callus growth phase. We observed that the best phase for the production of secondary compounds in calli of yerba mate is the stationary growth phase on both genotypes tested. In this phase, higher levels of phenolic compounds, chlorogenic acid and 3,5 - dicaffeoylquinic acid and greater antioxidant activity were observed. Chlorogenic acid and 3,5 - dicaffe oylquinic acid presented positive correlation with antioxidant activity. For the first time, secondary compounds were reported in yerba mate calli cultivated in vitro .

Estos compuestos se han producido in vitro mediante cultivo de ca llos de diferentes especies. Sin embargo, para I. paraguariensis , hasta la fecha no se han realizado estudios sobre la producción de estos compuestos in vitro . En este trabajo, mostramos que la concentración de metabolitos secundarios desde callos de I. pa raguariensis es posible y altamente dependiente de la fase de crecimiento del callo. Observamos que la mejor fase para la producción de compuestos secundarios en callos de yerba mate es la fase de crecimiento estacionario en ambos genotipos probados. En es ta fase se observaron niveles más altos de compuestos fenólicos, ácido clorogénico y ácido 3,5 - dicafeoilquínico y una mayor actividad antioxidante. El ácido clorogénico y el ácido 3,5 - dicafeoilquínico presentaron correlación positiva con la actividad antio xidante. Por primera vez, se reportaron compuestos secundarios en callos de yerba mate cultivados in vitro .

Abstract The present work aims to study which factors are relevant in long-term mate selection from a lonely-hearts personal advertisement sample of Spanish-speaking consumers of Cosmopolitan Magazine, Colombian Edition. We analyzed One thousand four hundred sixty-eight publications (made by 770 men and 698 women) using a coding system based on the theories of sexual strategies, genetic quality indicators, and the preferences classification used in personal ads studies. Initially, we found trends as a greater predilection for psychological attributes and a greater demand to require more traits than offering them. In addition, the cross-cultural pattern demonstrated that men prefer women's physical characteristics, while women require status/resources by men. Finally, men tended to be more selective in the age range of 36-45 years, while women's selectivity decreased with age. The results replicate many of the patterns found in investigations related to human sexual selection, also bring enlightenment about new preference dimensions to study in the future.
Resumen La presente investigación examina las preferencias de individuos que buscan emparejarse a largo plazo, por medio del análisis de anuncios de búsqueda de parejas, publicados por una muestra de usuarios hispanohablantes de la edición Colombiana de la Revista Cosmopolitan. Se revisaron 1468 publicaciones (de 770 hombres y 698 mujeres) utilizando un sistema de codificación construido a partir de la teoria de estrategias sexuales, indicadores de calidad genética y clasificaciones usadas en estudios de anuncios personales. Los usuarios reportaron una mayor atención por atributos psicológicos, además de una alta exigencia. Adicionalmente, los hombres solicitaron más características fisicas de las mujeres, y las mujeres más indicadores asociados al estatus y recursos de los hombres. Los hombres se mostraron más selectivos entre los 36 y los 45 anos, mientras que la selectividad de las mujeres disminuyó con la edad. Los resultados replican patrones encontrados en las investigaciones sobre emparejamiento sexual humano, y dan luces sobre nuevos dominios de preferencia para examinar en el futuro.
ABSTRACT
ObjectiveTo form a questionnaire of high reliability and validity on mate preferences of postgraduates in military academy. MethodsIn December 2020, full-time postgraduates of a military academy were randomly selected as research objects, and their mate preferences were investigated via a self-compiled open-ended questionnaire. The item screening and expert consultation were carried out to compile an initial questionnaire on mate preferences of the postgraduates in military academy, and the questionnaire survey was conducted on 89 postgraduates in the military academy. Then the item analysis and exploratory factor analysis were performed to test the questionnaire, and the reliability and validity of the questionnaire were tested by calculating Pearson correlation coefficient, Cronbach's α coefficients and split-half coefficient. ResultsThe questionnaire on mate preferences of postgraduates in military academy has been formed, which consisting of 4 factors (intrinsic quality, personal ability, external conditions and quality of life) and 25 items was formed. The correlation coefficient between the total score of the questionnaire and the score of each factor ranged from 0.739 to 0.864, Cronbach's α coefficient of total score and each factor ranged from 0.723 to 0.926, and the split-half coefficient was between 0.682 and 0.899. ConclusionThe compiled questionnaire on mate preferences of postgraduates in military academy has good credibility and validity, and can be used as a tool to collect the data of psychological marriage and love on the mate preferences of postgraduates in military academy.
ABSTRACT
O presente estudo avaliou as características desejadas em um parceiro virtual quando há intenção de se casar ou ficar. Uma amostra de 210 estudantes universitários respondeu a um questionário com questões elaboradas pelos pesquisadores e a Escala de Atributos do Parceiro Ideal. Verificou-se qual a intenção amorosa dos sujeitos ao utilizarem os aplicativos, a quantidade de encontros concretizados e o tempo de acesso a eles. Os resultados mostraram que as características desejadas em um parceiro para ficar e em um para casar são diferentes, assim como as intenções amorosas entre os sexos e a quantidade de encontros que concretizaram. O tempo de acesso aos aplicativos foi semelhante e as mulheres consideraram que os homens criam mais expectativas sobre o desenvolvimento de um namoro por ferramentas virtuais. Concluiu-se que os homens são mais propensos ao envolvimento sexual casual.
The present study evaluated the desired characteristics in a virtual partner when one wanted to marry or date. A sample of 210 university students answered a questionnaire that contained questions elaborated by the researchers and the Scale of Attributes of the Ideal Partner. It was verified the subjects' loving intention in using the applications, the number of encounters made and the time of access to them. The results demonstrated that the characteristics desired in a partner to date and to marry are different, as well as the love intentions between the sexes and the amount of dates that have materialized. Access time to applications was similar and women considered that men created more expectations about developing relationship by virtual tools. It is concluded that men are more prone to casual sexual involvement.

Resumen La reproducción sexual es uno de los grandes hitos de la evolución de la vida en la Tierra; si bien pudo facilitar la generación de variabilidad genética, también impuso una serie de retos adaptativos en los organismos, tales como la búsqueda de parejas y las estrategias para asegurar la reproducción. La teoría de selección sexual ofrece hipótesis que permiten explicar cómo la búsqueda y la selección de parejas no son aleatorias o arbitrarias en los organismos complejos. Se plantea que existen unos criterios para seleccionar parejas reproductivas que se ven reflejados en mecanismos psicológicos denominados preferencias, las cuales pueden orientar la elección de parejas que tengan rasgos adaptativos y beneficiar o bien la supervivencia, o bien la reproducción futura de la descendencia que herede tales caracteres. El presente artículo aborda cómo las condiciones que impone la sexualidad moldean la evolución del comportamiento y cómo aquellos principios se aplican al emparejamiento humano. A partir de esto se plantean las principales preguntas que derivan de esta relación entre evolución, preferencias y selección de pareja.
Abstract Sexual reproduction is one of the greatest landmarks of the evolution of life on Earth. Although it helped the generation of genetic variability, it also imposed a series of adaptive challenges in organisms, such as the search for mates and strategies to secure reproduction. The theory of sexual selection offers hypotheses to explain that the search and selection of a mate are not arbitrary for complex organisms. It is proposed that there are criteria for selecting reproductive mates that are reflected in psychological mechanisms called preferences, which can guide the choice of partners who have adaptive traits and can benefit, either survival or future reproduction of the offspring that inherit such traits. This review addresses how the conditions imposed by sexuality shape the evolution of behavior, and how those principles apply to human mating behavior. From there, important questions arise to understand the relationship among evolution, preferences and mate selection.

Introducción: las enfermedades del aparato circulatorio constituyen la primera causa de muerte en la provincia de Misiones y el mate es una infusión de consumo masivo en la región. Objetivos: determinar la frecuencia del consumo de mate en jóvenes aparentemente sanos, y su relación con el sexo, la edad, el índice de masa corporal (IMC) y el perfil lipídico. Materiales y métodos: se completó un cuestionario para conocer los hábitos de consumo de yerba mate. Se midieron peso y talla para calcular el IMC. Las determinaciones bioquímicas se realizaron con ayuno de 12 horas; colesterol total y triglicéridos (TG) por método enzimático colorimétrico, colesterol-HDL (c-HDL) y colesterol-LDL por método homogéneo, en auto analizador Dimension RL MAX de Siemens. Se estudiaron 406 jóvenes, 188 varones y 218 mujeres. Resultados: el 76,4% consumía mate, mayor en mujeres (82,1%) que en varones (69,7%) (p=0,003). El consumo se asoció positivamente con la edad (p<0,001) y no se observó asociación con el IMC (0,989). En los consumidores de mate, TG (p=0,039),colesterol-no HDL (0,040), CT/c-HDL (p=0,001) y TG/c-HDL (p=0,001) fueron significativamente más bajos que en los no consumidores, mientras que el c-HDL (p=0,001) fue más alto. Conclusiones: el hallazgo de un efecto favorable sobre el perfil lipídico en jóvenes consumidores de yerba mate podría constituir un beneficio para la salud de quienes la consumen y aportaría valor agregado a la hora de la conquista de nuevos mercados por parte de la industria yerbatera
Introduction: diseases of the circulatory system are the leading cause of death in the province of Misiones and mate is an infusion of mass consumption in the region. Objectives: to determine the frequency of consumption of mate in apparently healthy young people and its relationship with sex, age, body mass index (BMI) and lipid profile. Materials and methods: a questionnaire was completed to know the consumption habits of yerba mate. Weight and height were measured to calculate BMI. Biochemical determinations were performed with a 12-hour fast; total cholesterol and triglycerides (TG) by colorimetric enzymatic method,HDL-cholesterol (c-HDL) and LDL-cholesterol by homogeneous method; in Siemens Dimension RL MAX auto analyzer.406 young people, 188 men and 218 women were studied. Results: 76.4% consumed mate, higher in women (82.1%) than in men (69.7%) (p=0.003). Consumption was positively associated with age (p<0.001) and no association was observed with BMI (p=0.989). In the consumers of mate; TG (p=0.039), non-HDL cholesterol (0.040), CT/c-HDL (p=0.001) and TG/c-HDL (p=0.001) were significantly lower than in non-consumers, while c -HDL (p = 0.001) was higher. Conclusions: the finding of a favorable effect on the lipid profile in young consumers of YM could constitute a health benefit for those who consume and provide added value when it comes to the conquest of new markets by the herb industry
