Discourses of power that underlie EFL teachers educational practices within the MLD at the PUJ in Bogotá

Esta investigación es un estudio de caso cualitativo, cuyo objetivo es describir los discursos de poder que subyacen a las prácticas educativas de los profesores de inglés en la Licenciatura de Lenguas Modernas en la PUJ de Bogotá y que contribuyen a mantener o transformar el status quo. La descripción del fenómeno está enmarcada dentro de tres conceptos principales: hegemonía, discursos de poder y prácticas educativas, considerando que la enseñanza del inglés (como de cualquier otra lengua) está directamente relacionada con el poder y no debe ser reducida a asuntos meramente procedimentales, lo que aleja el salón de clases de su contexto local y global. En un intento por develar el cimiento ideológico que permea la enseñanza del inglés en el contexto de expansión capitalista-globalización-, los datos muestran que esta dinámica política, económica y cultural influye en la orientación pedagógica de los profesores y por lo tanto en su práctica educativa.This research is a qualitative case study, whose objective is to describe the discourses of power that underlie EFL teachers educational practices within the Modern Languages Degree. Those discourses contribute either to maintain or to transform the status quo. The description of the phenomenon is framed within three core concepts: hegemony, discourses of power and educational practices, considering that teaching English (as any other language) is directly related to power and must not be reduced to procedural issues, what isolates the EFL classroom from its local and global context. In an attempt to unveil the ideological foundation that permeates English language teaching in the context of the capitalism spreading -globalization-, the data show that this economic, political and cultural dynamic influences teachers pedagogical orientation and therefore their educational practice.Licenciado (a) en Lenguas ModernasPregrad

The data were collected by semi-structured interview and analyzed by the Content Analysis method. Results: Sixteen professors participated. Five main themes emerged: competency definition, attributes to act with children, advances in the training of professional competency, challenges to enable training pediatric competency, and methods and instruments for evaluating competency acquisition to work in the area of pediatric nursing. Conclusion: The findings of this study point to the importance of a balanced approach in the cognitive, psychomotor and affective dimensions in training and evaluating professional competency in pediatric nursing, as well as extending the curricular valorization of this area of knowledge and practice

Importancia del diagnóstico precoz en el carcinoma mucoepidermoide. Relato de caso clínico

Mucoepidermoid carcinoma is the most frequent malignant tumor of the minor salivary glands, usually located in the palate. The objective of this case report is to demonstrate in the Paraguayan scientific literature the importance of early diagnosis of oral carcinomas as well as the fundamental role of the general dentist in identifying, guiding and referring the patient to the corresponding specialist. The clinical case presented is about a male patient who attended the Faculty of Dentistry of the National University of Asuncion. His dentist referred him after noticing a small but perceptible change in the normal coloration of the mucosa and occasional discomfort in the area of the hard palate. In the intraoral examination, an ovoid nodular lesion, purplish in color, 1cm in diameter, depressible on palpation, observed on the hard palate at the level of the premolars in the left hemiarch. An incisional biopsy performed for histopathological study, reporting a mucoepidermoid carcinoma. Regarding the early diagnosis of this type of pathology, the challenge for the general dentist will continues to be his continuous training in order to be able to successfully guide the patient in seeking care from the right specialist in case of any change in the oral cavity.El carcinoma mucoepidermoide es el tumor maligno más frecuente de las glándulas salivales menores localizándose por lo general en el paladar. El objetivo del presente reporte de caso es evidenciar en la literatura científica la importancia del diagnóstico precoz de carcinomas orales, así como, el rol fundamental que cumple el odontólogo general para identificar, guiar y derivar al paciente a un especialista. Se presenta el caso clínico de un paciente de sexo masculino que acudió a la Facultad de Odontología de la Universidad Nacional de Asunción, quien fue derivado por su odontóloga tras percibir un pequeño pero perceptible cambio en la coloración normal de la mucosa y molestias ocasionales en la zona del paladar duro. Al examen intraoral se observó en el paladar duro, a la altura de los premolares en la hemiarcada izquierda, una lesión nodular ovoidea, color violáceo, de 1cm de diámetro, depresible a la palpación. Se realizó una biopsia incisional para su estudio histopatológico, reportando un carcinoma mucoepidermoide. El diagnóstico precoz de este tipo de patologías es un desafío para el odontólogo general, quien debe orientar al paciente, ante cualquier cambio de la estructura normal de la cavidad bucal, para que acuda a un especialista

Pyruvate supplementation in cotton under water restriction varying the phenological phases

Cotton is one of the largest agricultural commodities that generate various sources of foreign exchange and employment worldwide. However, water deficiency is an environmental factor that limits the production of this crop, especially in semi-arid regions. We evaluated pyruvate supplementation to mitigate the effects of water stress on colored cotton. Experiments were conducted in a greenhouse. We studied two forms of pyruvate supplementation (SP1- via seed and foliar and SP2- only via foliar); three conditions of irrigation management of the plants: water restriction in the vegetative phase (VE), flowering (FL), and vegetative and flowering (VE/FL); and additional treatment (total irrigation throughout the crop cycle and without pyruvate supplementation). The experimental design included a randomized block in a 2 × 3 + 1 factorial scheme. The factors resulted in seven treatments with three replications, with a total of 21 experimental units. Gas exchange, enzyme activity, and production of components were evaluated. Water restriction in the vegetative phase does not cause losses in BRS Jade cotton when supplemented with pyruvate. However, in the flowering and vegetative phases plus flowering, it reduces gas exchange and production components and increases the activity of antioxidant enzymes in relation to plants under full irrigation. Supplementation with pyruvate via seed plus foliar (SP1) was better for BRS Jade cotton grown under water restriction

Hemotropic Mycoplasma spp. in Aquatic Mammals, Amazon Basin, Brazil

4 Pág. Centro de Investigación en Sanidad Animal (CISA)Hemotropic Mycoplasma spp. (hemoplasmas) are uncultivable bacteria that infect mammals, including humans. We detected a potentially novel hemoplasma species in blood samples from wild river dolphins in the Amazon River Basin, Brazil. Further investigation could determine pathogenicity and zoonotic potential of the detected hemoplasma.This study was funded by Brazilian National Council for Scientific and Technological Development (scholarship no. 141868/2019-8 and fellowship no. 304999-18), Fundação de Amparo à Pesquisa do Estado de São Paulo (scholarship no. 2016/20956-0 and grant no. 2018/25069-7), and by the Juan de la Cierva incorporación and formación fellowship nos.

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal

Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and Joshua Quick and Nick Loman (University of Birmingham) for kindly providing us with the initial sets of Artic Network primers for NGS; Rafael Mamede (MRamirez team, IMM, Lisbon) for developing and sharing a bioinformatics script for sequence curation (https://github.com/rfm-targa/BioinfUtils); Philippe Lemey (KU Leuven) for providing guidance on the implementation of the phylodynamic models; Joshua L.

Rising rural body-mass index is the main driver of the global obesity epidemic in adults

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.Peer reviewe

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: a pooled analysis of 2181 population-based studies with 65 million participants

Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
