ABSTRACT School management plays a crucial role in the development of inclusive practices in education. Effective management of the educational institution enables the creation of an inclusive school environment that values and promotes the diversity of its students. Thus, this study aimed to determine the relationship between school management and inclusive practices in education. It was based on a quantitative approach and two questionnaires were applied to 72 teachers to measure their perception of school management and inclusive practices in the institution. The results showed a high correlation between the variables school management and inclusive practices, as well as a high correlation between the organizational, administrative, pedagogical and community dimensions of school management and the variable inclusive practices. In conclusion, school management and inclusive practices are closely related and both are fundamental to achieve inclusive and quality education for all students.

Abstract Introduction: Pediatric ulcerative colitis (CUP), pediatric Crohn’s disease (PCD), and pediatric inflammatory bowel disease not classifiable (PIDNCID) have clinical and psychosocial particularities that differentiate them from those of adults and may condition different therapeutic approaches due to possible nutritional, growth and developmental repercussions, representing a challenge for the pediatrician and gastroenterologist. Objective: Develop expert consensus evidence-based recommendations for the timely and safe diagnosis and treatment of Pediatric Inflammatory Bowel Disease (PID) in children under 18 years of age for professionals caring for these patients and healthcare payers. Methodology: Through a panel of experts from the Colombian College of Pediatric Gastroenterology, Hepatology and Nutrition (COLGAHNP) and a multidisciplinary group, 35 questions were asked regarding the clinical picture, diagnosis, and treatment of PID. Through a critical review and analysis of the literature with particular emphasis on the main clinical practice guidelines (CPGs), randomized clinical trials (RCTs), and meta-analyses of the last ten years, from which the experts made 77 recommendations that responded to each of the research questions with their respective practical points. Subsequently, each of the statements was voted on within the developer group, including the statements that achieved > 80%. Results: All statements scored > 80%. PID has greater extension, severity, and evolution towards stenosis, perianal disease, extraintestinal manifestations, and growth retardation compared to adult patients, so its management should be performed by multidisciplinary groups led by pediatric gastroenterologists and prepare them for a transition to adulthood. Porto’s criteria allow a practical classification of PID. In CPE, we should use the Paris classification and perform ileocolonoscopy and esophagogastroduodenoscopy, since 50% have upper involvement, using the SES-CD (UCEIS/Mayo in CUP) and taking multiple biopsies. Initial labs should include inflammatory markers and fecal calprotectin and rule out intestinal infections. Treatment, induction, and maintenance of PID should be individualized and decided according to risk stratification. Follow-up should use PCDAI and PUCAI for the last 48 hours. Immunologists and geneticists should evaluate patients with early and infantile PID. Conclusion: A consensus guideline is provided with evidence-based recommendations on timely and safe diagnosis and treatments in patients with ILD.

Abstract Cocoa (Theobroma cacao L.) is one of the most important economic crops worldwide. The propagation of elite varieties of cocoa has been achieved through somatic embryogenesis, but still one of the main limitations is the low rates of embryo formation, which is a genotype-dependent trait. Manipulation of transcription factors (TFs) such as BABY BOOM (BBM) promotes the transition of cocoa somatic cells from the vegetative to the embryonic state. This work validated the use of clonal cocoa leaves cv. IMC-67 to induce somatic embryogenesis, overcoming their recalcitrant limitation with the help of the introduction of TF-BBM from Arabidopsis thaliana (AtBBM). The vectors were constructed by the Gateway system using the donor vector pENTR/D-TOPO and the expression vector pk7WG2. The overexpression vector pk7WG2:AtBBM was obtained, allowing successful transformation into Agrobacterium tumefaciens GV3101. The AtBBM gene was characterized (1755 base pairs), and its expression was observed in the formation of embryogenic calluses in cocoa leaves. Overexpression of AtBBM allowed the obtainment of a 92% response in the formation of embryogenic callus in cocoa leaves with Agrobacterium-mediated vacuum infiltration and overexpression of the pk7WG2:AtBBM vector. This high transformation efficiency reached with the insertion of the overexpression vector provides validation of transient response of the TF AtBBM in the formation of embryogenic calluses in cocoa leaves of the IMC-67 clone. Through this methodology, it is possible to continue with studies of gene overexpression, insertion, silencing, and gene editing in Peruvian cocoa.

Abstract Coffee leaf rust (Hemileia vastatrix) is the most important disease in coffee crops around the world. Currently, there is limited knowledge about mass production methodologies and ex-situ infection of H. vastatrix that lead to the development of different health characterization studies of Coffea or disease phenotyping. In this context, the aim of this research was to develop a simple protocol for the mass production of coffee rust uredospores under controlled conditions and to determine their infection in coffee seedlings. Uredospores of H. vastatrix were collected from infected plants in the “Chontal” coffee-growing area in San Martín, Peru. The viability of uredospore germination was evaluated, and a uredospores suspension (2 x 105 uredospores/mL) was prepared to inoculate coffee seedlings. Incidence and sporulation rates were evaluated after 43 days of inoculation. During the multiplication process of H. vastatrix uredospores, using controlled conditions (23±1 °C, ≈ 80% relative humidity and photoperiod of 16 hours of light) under an innovative system, the first symptoms of chlorosis were observed on coffee leaves 20 days after inoculation. Our findings show a 100% incidence of inoculated coffee plants with an average of 54 mg of H. vastatrix uredospores per plant and a 1.38 x 10-1 mg/cm2 sporulation rate. Finally, here we report a protocol that allows mass multiplication of H. vastatrix uredospores under controlled conditions, that would be useful in any time for coffee leaf rust bioassays.

Resumen El estigma es un fenómeno caracterizado por una respuesta negativa hacia una persona poseedora de un atributo diferente dentro del grupo social en el que se desarrolla. Se han descrito dos tipos de estigma: el percibido (sentido o interiorizado) y el promovido (social o promulgado). Dentro de las enfermedades con más carga asociada a estigma se encuentra la epilepsia, una de las enfermedades neurológicas más prevalentes a nivel mundial y de curso crónico. En los últimos años, se ha mostrado mayor interés en el estudio de este fenómeno, ya que afecta de manera directa la calidad de vida de las personas con epilepsia, influyendo en su desarrollo personal, escolar, laboral y pronóstico.

Abstract Stigma is a phenomenon characterized by a negative response to a person possessing a different attribute within the social group it develops. Two types of stigmas have been described: perceived (felt) and promoted (enacted). Among the diseases with the greatest burden associated with stigma is epilepsy, one of the most prevalent neurological diseases worldwide and with a chronic course. In recent years, greater interest has been shown in the study of this phenomenon since it directly affects the quality of life of people with epilepsy, influencing their personal, academic and work development and prognosis.

Abstract: As a contribution to the study of video poetry produced by women, one of the first video poems ever produced in the Americas will be analyzed and discussed. In this work, the artist is committed to a decided and rhizomatic deterritorialization of the written poem, proposing an audiovisual creation that irreverently tears apart the figure of the authority of the male poet. Becerra Cano uses various types of translations to video-graphically trace a hybrid spacetime of potential nomadic and poetic creation, responding to the contemporary cultural and technological context with historical gender and colonial implications.

Resumen: Como contribución al estudio de la producción de videopoesía hecha por mujeres, se analiza y discute una de las primeras obras de videopoesía producida en el continente americano. En esta obra la artista, Margarita Becerra Cano, apuesta por una decidida y rizomática desterritorialización del poema escrito y propone una creación audiovisual que con irreverencia desgarra la figura de la autoridad del poeta hombre. La autora recurre a diversos tipos de traducciones a fin de trazar videográficamente un espacio-tiempo híbrido de potencial creación poética nómada que responda al contexto cultural y tecnológico contemporáneo con históricas implicaciones de género y coloniales.

Abstract Background: Cardiovascular diseases are the leading cause of mortality worldwide and Mexico is no exception. The epidemiological data obtained in 1990 showed that cardiovascular diseases represented 19.8% of all causes of death in our country. This figure increased significantly to 25.5% for 2015. Some national surveys suggest that more than 60% of the adult population has at least one risk factor for cardiovascular disease (obesity or overweight, hypertension, smoking, diabetes, dyslipidemias). On the other hand, data from the Pan American Health Organization have linked the process of atherosclerosis as the first cause of premature death, significantly reducing life expectancy, which has enormous social repercussions. Objective: This document constitutes the Clinical Practice Guide (CPG) prepared at the initiative of the Mexican Society of Cardiology in collaboration with the Mexican Society of Nutrition and Endocrinology, AC, National Association of Cardiologists of Mexico, AC, Mexican Association for the Prevention of Atherosclerosis and its Complications, AC, National Normative Committee of General Medicine, AC, National College of Geriatric Medicine, AC, College of Internal Medicine of Mexico, AC, Mexican Society of Angiology and Vascular and Endovenous Surgery, AC, Mexican Institute of Research Nephrological, AC and the Mexican Academy of Neurology, A.C.; with the methodological support of the Ibero-American Agency for the Development and Evaluation of Health Technologies, in order to establish recommendations based on the best available evidence and agreed upon by an interdisciplinary group of experts. The objective of this document is to provide evidence-based recommendations to help decision makers in the diagnosis and treatment of dyslipidemias in our country. Material and methods: This document complies with international quality standards, such as those described by the Institute of Medicine of the USA, the Institute of Clinical Excellence of Great Britain, the Scottish Intercollegiate Guideline Network and the Guidelines International Network. A multidisciplinary group of clinical experts and methodologists with experience in systematic reviews of the literature and the development of clinical practice guidelines was formed. A scope document was agreed upon, relevant clinical questions were established, the best available evidence critically evaluated in systematic literature reviews was exhaustively identified, and clinical recommendations were developed. The modified Delphi Panel methodology was used to achieve an adequate level of consensus in each of the recommendations contained in this CPG. Results: 23 clinical questions were agreed upon which gave rise to their respective clinical recommendations. Conclusions: We consider that this document contributes to better clinical decision-making and becomes a point of reference for clinicians and patients in the management of dyslipidemias and this contributes to reducing the morbidity and mortality derived from atherosclerotic cardiovascular events in our country.

Resumen En el año 2014, la Unión Europea impuso estándares máximos de tolerancia en cadmio, para la importación de productos a base de cacao, causando preocupación en los países. Se analizó estudios globales referidos a investigaciones en Theobroma cacao, relacionados con la actividad del cadmio en la atmósfera. Se utilizaron análisis bibliométricos en los programas R y VOSviewer, para examinar 64 documentos publicados en la base de datos Scopus según palabras clave. Se identificaron 811 palabras clave en coocurrencias de términos, 5 grupos temáticos en acoplamiento bibliográfico, 20 instituciones como afiliaciones más importantes, 20 países de procedencia de autores corresponsales, 112 instituciones en red de coautoría de los cuales 5 están en documentos primarios, y dos grupos en similaridad temática en co-citación de documentos. Estados Unidos lidera la producción científica con 11 documentos, seguido de Colombia (8) y Ecuador (7). En 1996 se registró el primer artículo científico para la red, con incrementos de hasta 11 publicaciones al 2020. En conclusión, se evidencia la necesidad de fortalecer y crear más redes de investigaciones entre países, instituciones, autores y coautores. Se espera que los resultados permitan desentrañar de manera integral la trayectoria de investigaciones cadmio-cacao, al tiempo que arrojen nuevas investigaciones prospectivas.

Abstract The maximum cadmium tolerance standards were established by the European Union in 2014, for the importation of cocoa-based products, causing concern in the countries. Global studies onTheobroma cacaoresearch related to cadmium activity in the atmosphere were analyzed. Bibliometric analyses in R and VOSviewer programs were used to examine 64 documents published in the Scopus database according to keywords. We identified 811 keywords in the co-occurrence of terms, 5 thematic groups in the bibliographic coupling, 20 institutions as most important affiliations, 20 countries of origin of corresponding authors, 112 institutions in co-authorship network of which 5 are in primary documents, and two groups in thematic similarity in co-citation of documents. The United States leads the scientific production with 11 papers, followed by Colombia (8) and Ecuador (7). In 1996, the first scientific article was registered for the network, with increases of up to 11 publications by 2020. In conclusion, the need to strengthen and create more research networks between countries, institutions, authors, and co-authors is evident. It is hoped that the results will allow a comprehensive unraveling of the cadmium-cocoa research trajectory, while at the same time yielding new prospective research.

Resumen La pandemia de infección por SARS-CoV-2, causante de COVID-19, ha afectado profundamente a los sistemas de salud y ha ocasionado un enorme impacto en las familias, las comunidades y las naciones. La estrategia de respuesta integral requiere que además de las consideraciones epidemiológicas, científicas y técnicas, no se olvide el sufrimiento humano asociado a la enfermedad, la vulnerabilidad y la muerte. La atención paliativa a personas con sospecha o diagnóstico de COVID-19 con evolución grave y sus familias debe ser también parte clave de la acción organizada que ayude al alivio del sufrimiento y mejore la calidad de vida mediante el control de los síntomas, el abordaje de las necesidades psicológicas, sociales y espirituales, el apoyo para la planificación de la atención avanzada y la articulación de los objetivos de la misma, el cuidado de la persona en la fase final de la vida, así como el soporte ante la toma de decisiones complejas y problemas éticos, entre otros. Se ofrecen recomendaciones para brindar los cuidados paliativos en el contexto de la pandemia de COVID-19.

Abstract The pandemic of SARS-CoV-2 infection, which causes COVID-19, has deeply affected health systems and has had a significant impact on families, communities and nations. A comprehensive response strategy requires in addition to epidemiological, scientific and technical considerations, for human suffering associated with disease, vulnerability and death not to be forgotten. Palliative care for people with suspicion or diagnosis of COVID-19 with serious evolution and their families should also be a key part of organized actions that helps alleviate suffering and improve quality of life by controlling symptoms, addressing psychological, social and spiritual needs, support for advanced care and its goals, end-of-life care, as well as support in complex decision-making and ethical problems, among others. Recommendations are provided for offering palliative care in the COVID-19 pandemic context.

Resumen Monascus purpureus es utilizado en la industria alimentaria como un pigmento natural, principalmente por los países asiáticos; sin embargo, este hongo produce una micotoxina llamada citrinina, que causa enfermedades como hepatotoxicidad, teratogenicidad, tumores y mutaciones, en mamíferos. Este hongo fue encontrado en Serbia en ensilaje de maíz y alfalfa. El objetivo de este trabajo fue identificar la presencia del hongo Monascus purpureus en ensilaje de maíz, avena, triticale y alfalfa, el muestreo se realizó en los periodos de noviembre-diciembre de 2017 y abril-mayo de 2018, en los estados de Jalisco, Zacatecas, Aguascalientes y Guanajuato de la República Mexicana, se realizaron aislamientos de los ensilajes en medio Papa Dextrosa Agar (PDA), fueron identificados morfológicamente y molecularmente. Se obtuvieron 63 cepas diferentes, siete fueron Monascus purpureus, una en alfalfa, dos en maíz, dos en avena y dos en triticale. Esta investigación reporta por primera vez, la presencia de hongos Monascus purpureus en los ensilajes de maíz, avena, triticale y alfalfa.

Abstract Monascus purpureus is used in the food industry as a natural pigment, mainly by Asian countries; however, this fungus produces a mycotoxin called citrinin, which causes diseases such as hepatotoxicity, teratogenicity, tumors and mutations, in mammals. This fungus was found in Serbia in corn and lucerne silage. The objective of this work was to identify the presence of the Monascus purpureus fungus in corn, oats, triticale and lucerne silage, the sampling was carried out in the periods of November December 2017 and April-May 2018, in the states of Jalisco, Zacatecas, Aguascalientes and Guanajuato of the Mexican Republic, silage isolation was carried out in the middle of Papa Dextrosa Agar (PDA), they were morphologically and molecularly identified. 63 different strains were obtained, seven were Monascus purpureus, one in lucerne, two in corn, two in oats and two in triticale. This research reports, for the first time, the presence of Monascus purpureus fungi in corn, oats, triticale and lucerne silages.

Resumen La hemorragia de tubo digestivo bajo (HTDB) se define como la originada distal a la válvula ileocecal; su presentación clínica puede ser con hematoquecia, rectorragia o melena. La evaluación inicial debe incluir historia clínica rápida, examen físico y estudios de laboratorio para determinar la severidad de la hemorragia, etiología y posible localización de esta. El primer paso en el tratamiento de la hemorragia aguda de tubo digestivo bajo es evaluar el estado hemodinámico y la reanimación intensiva antes de realizar colonoscopia, que se mantiene como el método diagnóstico y terapéutico de elección. La información específica sobre su tratamiento es escasa por lo que el manejo suele adaptarse de las recomendaciones sobre el manejo de la hemorragia de tubo digestivo alto. También, a pesar de la existencia de diversas guías internacionales, su aplicación y disponibilidad en Mexico es limitada, por lo que la Asociación Mexicana de Endoscopia Gastrointestinal convocó a un grupo de gastroenterólogos, endoscopistas y coloproctólogos para revisar los avances en el manejo de la HTDB. La presente guía se enfoca en el origen, abordaje, tratamiento y seguimiento de la HTDB de acuerdo con directrices internacionales y a la disponibilidad de recursos humanos y tecnológicos en nuestro país. Para su realización se utilizó el método Delphi. La evaluación de la evidencia y grado recomendación se realizó utilizando el sistema GRADE (Grading of Recommendations, Assessment, Development and Evaluation) modificado.

Abstract Lower gastrointestinal bleeding (LGIB) localizes distal to the ileocecal valve. It presents either as hematochezia, rectal bleeding and melena in some cases. Initial approach must include a complete and detailed clinical and physical exam, laboratory exams in order to determine the severity and source of the hemorrhage. The first step in the treatment of LGIB is to asses and stabilize the patient hemodynamic status and prepare for colonoscopy, which remains the best diagnostic and therapeutic tool. Although LGIB accounts for a significant number of emergencies an hospital admissions, management information usually comes from data obtained and adjusted for upper gastrointestinal bleeding studies. Despite several guidelines have been published, its availability and applicability in our country is limited, therefore, the Asociación Mexicana de Endoscopia Gastrointestinal summoned a group of gastroenterologists, endoscopists and colon and rectum surgeons in order to review, discuss and grade current data on LGIB in order to develop management recommendations for LGIB. The resultant guideline focuses on the etiology, management and follow up of patients presenting LGIB in accordance to international standards and resources available in our country. Guidelines were developed using the Delphi method and evidence was grades using the modified Grading of Recommendations, Assessment, Development and Evaluation System).

ABSTRACT An assay on tilapia Oreochromis niloticus and freshwater prawn Macrobrachium americanum in polyculture was conducted during 112 days to study the effect on their blood chemistry and biochemical body composition to determine the feasibility of this polyculture in high density. Six densities were evaluated [T4/5, T9/5, T14/5, T0/5, T9/0, and T14/0; [Ttilapia/prawn (ind m-2)]. In tilapia were evaluated hemoglobin, red cells albumin, globulin, cholesterol, glucose, and triglycerides composition in blood. In M. americanum were evaluated hemocyanin, cholesterol, triglycerides, glucose and total protein in hemolymph. The total content of proteins, lipids, and carbohydrates in muscle and liver of tilapia, and muscle and hepatopancreas on prawns were also studied. Both animals presented significant differences (P < 0.05) in the glucose concentration, tilapia at T9/5 density presented significantly lower concentration (26.25 ± 6.3 mg dL-1) in blood, and prawn at T4/5 presented significant higher concentration (12.2 ± 1.9 mg dL-1). Tilapia monocultures T14/0 displayed significant higher (P < 0.05) carbohydrate concentration in muscle. No significant differences (P > 0.05) appeared in the concentration of lipids and proteins in any tilapia group and proximal composition of muscle and hepatopancreas in prawn. The present study indicates that polyculture in a density T14/5 is similar than monoculture with no effect in blood or hemolymph chemistry and proximal composition of tilapia and prawn. The blood glucose concentration can be considered an indicator of physiological changes for tilapia and prawn when cultured together.

RESUMEN: El objetivo del estudio fue analizar la producción de leche y las características de la curva de lactación de grupos genéticos ovinos. Se analizaron 863 registros semanales de producción de 70 lactaciones de seis grupos genéticos: East Friesian (EF), Criollo (Cr), EF ½ Cr ½ (EF50Cr50), EF 3/4 Cr ¼ (EF75Cr25), Suffolk ½ Cr ½ (Suffolk50Cr50), y Corriedale (C). Se utilizó la función de Wood (WD) para estimar la producción láctea total observada (PLT obs ) y estimada a los 180 d (PLT180), pico de lactación (PL), tiempo al pico de lactación (tPL) y persistencia (Per). El grupo genético influyó de forma significativa (p < 0.05) sobre la PLT obs , PLT180, PL y parámetro b del modelo de WD, con valores superiores en las ovejas EF50Cr50. Las diferencias en el desempeño productivo con el grupo genético pueden estar asociadas con la capacidad de adaptación de las ovejas EF a las condiciones climáticas locales.

ABSTRACT: The objective of the study was to analyze the milk production and characteristics of the lactation curve of ovine genetic groups. We analyzed 863 weekly production records of 70 lactations of six genetic groups: East Friesian (EF), Criollo (Cr), EF ½ Cr ½ (EF50Cr50), EF 3/4 Cr ¼ (EF75Cr25), Suffolk ½ Cr ½ (Suffolk50Cr50), and Corriedale (C). Wood's function (WD) was used to estimate the total observed milk production (TMP obs ) and estimated at 180 d (TMP180), lactation peak (LP), time to lactation peak (tLP) and persistence (Per). The genetic group had a significant influence (p < 0.05) on tTMP obs , TMP180, LP and parameter b of the WD model, with higher values in the EF50Cr50 sheep. The differences in productive performance with the genetic group may be associated with the adaptability of EF sheep to local climatic conditions.

Abstract: This study aims to evaluate the clinicopathological features, TNM status, AJCC staging and behavior of squamous cell carcinoma of the tongue (SCCT) in patients older than 45 years. The files of the Department of Pathology of the Hospital General de México were reviewed and all cases of SCCT in patients older than 45 years were selected. Clinicopathological features, treatment, follow-up, microscopic diagnosis, and IJCC and TNM staging were retrieved. Complete data from 60 cases were evaluated. They were more common in males (mean age = 63.9 years). Unexpectedly a high rate of tumors (38.3%) were in the base of the tongue (BT). Moderately and poorly differentiated SCCT were the most common. 16.7% presented lymph node invasion, 15% were recurrent tumors and BT carcinomas recurred more frequently. A high rate (81.7%) were stage II and 48.3% were low-risk patients. SCCTs in the studied population displayed different clinico-pathological and behavioral features compared with worldwide data. Our results suggest that BT tumors should be treated more aggressively than those in the mobile tongue. BT located tumors were more frequent than previously published. Additional frequency studies will define outcomes in age cohorts with a consensus cut-off for young and elderly populations. More population-based studies should be performed in Latin American regions to acquire accurate data on SCC incidence in elder subpopulations and to identify precisely the etiological factors in these patients.

Abstract Giant Osteosclerotic Lesions (GOLs) are a group of rarely reported intraosseous lesions. Their precise diagnosis is important since they can be confused with malignant neoplasms. Objective This retrospective study aimed to record and analyze the clinical and radiographic Giant Osteosclerotic Lesions (GOLs) detected in the maxillomandibular area of patients attending to our institution. Materials and Methods: Informed consent from the patients was obtained and those cases of 2.5 cm or larger lesions with radiopaque or mixed (radiolucid-radiopaque) appearance located in the maxillofacial bones were selected. Assessed parameters were: age, gender, radiographic aspect, shape, borders, size, location and relations to roots. Lesions were classified as radicular, apical, interradicular, interradicular-apical, radicular-apical or located in a previous teeth extraction area. Additionally, several osseous and dental developmental alterations (DDAs) were assessed. Results Seventeen radiopacities in 14 patients were found and were located almost exclusively in mandible and were two types: idiopathic osteosclerosis and condensing osteitis. GOLs were more frequent in females, and in the anterior and premolar zones. 94.2% of GOLs were qualified as idiopathic osteosclerosis and one case was condensing osteitis. All studied cases showed different osseous and dental developmental alterations (DDAs). The most common were: Microdontia, hypodontia, pulp stones, macrodontia and variations in the mental foramina. Conclusions GOLs must be differentiated from other radiopaque benign and malignant tumors. Condensing osteitis, was considered an anomalous osseous response induced by a chronic low-grade inflammatory stimulus. For development of idiopathic osteosclerosis, two possible mechanisms could be related. The first is modification of the normal turnover with excessive osseous deposition. The second mechanism will prevent the normal bone resorption, arresting the osseous breakdown process.
