Population genetics structure of glyphosate-resistant Johnsongrass (Sorghum halepense L. Pers) does not support a single origin of the resistance

Single sequence repeats (SSR) developed for Sorghum bicolor were used to characterize the genetic distance of 46 different Sorghum halepense (Johnsongrass) accessions from Argentina some of which have evolved toward glyphosate resistance. Since Johnsongrass is an allotetraploid and only one subgenome is homologous to cultivated sorghum, some SSR loci amplified up to two alleles while others (presumably more conserved loci) amplified up to four alleles. Twelve SSR providing information of 24 loci representative of Johnsongrass genome were selected for genetic distance characterization. All of them were highly polymorphic, which was evidenced by the number of different alleles found in the samples studied, in some of them up to 20. UPGMA and Mantel analysis showed that Johnsongrass glyphosate-resistant accessions that belong to different geographic regions do not share similar genetic backgrounds. In contrast, they show closer similarity to their neighboring susceptible counterparts. Discriminant Analysis of Principal Components using the clusters identified by K-means support the lack of a clear pattern of association among samples and resistance status or province of origin. Consequently, these results do not support a single genetic origin of glyphosate resistance. Nucleotide sequencing of the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) encoding gene from glyphosate-resistant and susceptible accessions collected from different geographic origins showed that none presented expected mutations in aminoacid positions 101 and 106 which are diagnostic of target-site resistance mechanism.Fil: Fernández, Luis.

Prepregnancy cardiovascular risk factors as predictors for hypertensive pregnancy disorders

Hypertensive disorders of pregnancy (HDP) are a group of conditions characterized by abnormally elevated blood pressure during pregnancy. HDP are one of the leading causes of maternal and fetal morbidity and mortality worldwide. There is growing evidence that prepregnancy cardiovascular risk factors significantly increase the risk of HDP. Along these lines, hypertension, diabetes mellitus, obesity, heart failure and hypercholesterolemia appear to be related to HDP. All of these can increase, to a lesser or greater degree, the risk of HDP. Although some of these variables are intertwined, they can also act as independent predictors. A preconceptional predictive tool could improve therapeutic decisions and pregnancy control in high-risk patients. This review aims to analyze the degree of correlation between HDP’s incidence and prepregnancy cardiovascular risk factors

Sex differences in the impact of frailty in elderly outpatients with heart failure

Introduction: Frailty is common among patients with heart failure (HF). Our aim was to address the role of frailty in the management and prognosis of elderly men and women with HF. Methods and results: Prospective multicenter registry that included 499 HF outpatients ≥75 years old. Mean age was 81.4 ± 4.3 years, and 193 (38%) were women. Compared with men, women were older (81.9 ± 4.3 vs. 81.0 ± 4.2 years, p = 0.03) and had higher left ventricular ejection fraction (46 vs. 40%, p < 0.001) and less ischemic heart disease (30 vs. 57%, p < 0.001). Women had a higher prevalence of frailty (22 vs. 10% with Clinical Frailty Scale, 34 vs. 15% with FRAIL, and 67% vs. 46% with the mobility visual scale, all p-values < 0.001) and other geriatric conditions (Barthel index ≤90: 14.9 vs. 6.2%, p = 0.003; malnutrition according to Mini Nutritional Assessment Short Formulary ≤11: 55% vs. 42%, p = 0.007; Pfeiffer cognitive test's errors: 1.6 ± 1.7 vs. 1.0 ± 1.6, p < 0.001; depression according to Yesavage test; p < 0.001) and lower comorbidity (Charlson index ≥4: 14.1% vs. 22.1%, p = 0.038). Women also showed worse self-reported quality of life (6.5 ± 2.1 vs. 6.9 ± 1.9, on a scale from 0 to 10, p = 0.012). In the univariate analysis, frailty was an independent predictor of mortality in men [Hazard ratio (HR) 3.18, 95% confidence interval (CI) 1.29-7.83, p = 0.012; HR 4.53, 95% CI 2.08-9.89, p < 0.001; and HR 2.61, 95% CI 1.23-5.43, p = 0.010, according to FRAIL, Clinical Frailty Scale, and visual mobility scale, respectively], but not in women. In the multivariable analysis, frailty identified by the visual mobility scale was an independent predictor of mortality (HR 1.95, 95% CI 1.04-3.67, p = 0.03) and mortality/readmission (HR 2.06, 95% CI 1.05-4.04, p = 0.03) in men. Conclusions: In elderly outpatients with HF frailty is more common in women than in men. However, frailty is only associated with mortality in men

Educación y actividad intraempresarial en egresados universitarios colombianos

This article analyzes entrepreneurship education from the perspective of curricular courses, extracurricular activities, and postgraduate or continuing education in universities; and seeks to contribute to the theoretical evidence of the positive relationship between intrapreneurial activity and education in Colombian universities. For this purpose, a descriptive, correlational and non-experimental study has used contingency tables and a binomial logistic regression model with 3,152 graduates of various undergraduate degree programs from 120 universities. The findings suggest that taking entrepreneurship courses, participating in extracurricular activities, and having additional training after undergraduate degree studies increases the probability of being an intrapreneur. However, the probability is not significant if the graduate participated simultaneously in curricular and extracurricular activities. Post-undergraduate training is the one with the highest odd ratio in the model.El artículo analiza la educación emprendedora en los cursos curriculares, las actividades extracurriculares y la formación de posgrado o continua en universidades, y busca aportar evidencia de la relación positiva entre actividad intraempresarial y educación en egresados de universidades colombianas. Para ello, se llevó a cabo un estudio descriptivo, correlacional y no experimental, a través de tablas de contingencia y un modelo de regresión logística binomial, con 3.152 egresados de diversos programas de pregrado de 120 universidades. Los hallazgos sugieren que el hecho de haber cursado asignaturas curriculares de emprendimiento, participar en actividades extracurriculares y tener formación adicional después del pregrado aumenta la probabilidad de que un egresado sea intraempresario. No obstante, la probabilidad no es significativa si el egresado participó, de manera simultánea, tanto en actividades curriculares como en extracurriculares. La formación posterior al pregrado es la que presenta un odd ratio mayor en el modelo
