In this research, a meticulous screening process was conducted using four servers: Drug Target Explorer, Swiss Target Predictor, SEA Predictor, and Target Hunter. The primary objective was to identify a series of potential biological targets related to the regulation of cell growth and apoptosis in cancer cells using cinnamic acid derivatives. This study focused on five specific targets, matrix metallopeptidase 9 (MMP9), apoptosis inducing factor (AIF), aldo-keto reductase family 1 member C3 (AKR1C3), aldo-keto reductase family 1 member B10 (AKR1B10), mitogen-activated protein kinase 14 (MAPK14), all of which are well known to play a significant role in cancer cell dynamics. To explore both molecular recognition and molecular dynamics, a series of in silico investigations (docking and molecular dynamics) were carried out using a collection of 14 cinnamic acid derivatives, including cinnamic acid phenethyl ester (CAPE) as a notable reference molecule due to its widely recognized anticancer effects. Furthermore, preliminary in vitro data revealed a potentially promising cytotoxic effect of (E)-N-[(3,4-dichlorophenyl)methyl]-3-(4-phenoxyphenyl)-2-propenamide (LQM755) on a human gastric adenocarcinoma cell-line (AGS cells), which are characterized by the overexpression of the MMP9 protein. Therefore, the chemical compound LQM755 provides an initial perspective in the field of cancer therapy. research servers Explorer Predictor Hunter derivatives MMP9, MMP , (MMP9) AIF, AIF (AIF) aldoketo aldo keto C AKR1C3, AKR1C3 AKRC AKR (AKR1C3) B B1 AKR1B10, AKR1B10 AKRB (AKR1B10) mitogenactivated mitogen activated MAPK14, MAPK14 MAPK (MAPK14) dynamics docking CAPE (CAPE effects Furthermore EN3,4dichlorophenylmethyl34phenoxyphenyl2propenamide EN34dichlorophenylmethyl34phenoxyphenyl2propenamide ENdichlorophenylmethylphenoxyphenylpropenamide E N 3,4 dichlorophenyl methyl 3 4 phenoxyphenyl 2 propenamide LQM (LQM755 cellline line AGS cells, cells) Therefore LQM75 therapy (MMP9 (AIF AKR1C (AKR1C3 AKR1B1 (AKR1B10 MAPK1 (MAPK14 EN3 4dichlorophenylmethyl34phenoxyphenyl2propenamide EN dichlorophenylmethyl 34 3, (LQM75 LQM7 (MMP (AKR1C AKR1B (AKR1B1 (MAPK1 dichlorophenylmethylphenoxyphenylpropenamide (LQM7 (AKR1B (MAPK (LQM

Summary: The floodplain of the San Pedro River, a fluvial-delta formation, is one of the coastal areas affected by marine intrusion during the last glaciation. In this region, agriculture is the main economic activity; however, intensive agricultural practices, the geological past, current interactions with the marine system and the transport of salts through sediments and water make this area susceptible to soil salinization. To characterize the salinity of the agricultural area of the San Pedro River floodplain, two soil samplings were carried out at 91 sites over a period of two years. Samples were taken from depths of 0.0 to 0.3 m and from 0.0 to 0.1 m to depths of 1 m and 3 m. Fifty groundwater samples were collected. Saturation extracts were obtained (1: θsat) from the soil samples. For the soil and groundwater extracts, the pH, EC, and major cations and anions were determined, the sodium adsorption ratio was calculated in the original and adjusted formulations (SAR or and SAR adj ), and the exchangeable sodium percentage (ESP) was ascertained. The pH, EC and SAR or of the groundwater ranged from 6.94 to 8.37, 199 to 4660 µS cm-1 and 0.16 to 32.30 (mmolc L-1)1/2, while in the saturation extracts, the pH, EC and SAR or ranged from 4.81 to 8.58, 0.08 to 72.4 dS m-1 and 0.11 to 33.09 (mmolc L-1)1/2, respectively. The salinity problems in the study area are closely related to the intrusion of salts from the marine system.

Resumen: La planicie del río San Pedro, que tiene una formación fluvio-deltaica, es una de las superficies costeras que fueron afectadas por la intrusión marina durante la última glaciación. En esta zona, la agricultura es la principal actividad económica, sin embargo, las actividades agrícolas intensivas, su pasado geo-morfológico, la actual interdependencia con el sistema marino y el transporte de sales a través de los sedimentos y aguas, hacen que esta región sea susceptible a la acumulación de sales en los suelos. Con el objetivo de caracterizar la salinidad de la superficie agrícola de la planicie del río San Pedro, se hicieron dos muestreos de suelos en 91 sitios en un periodo de dos años. Se tomaron muestras de 0.0 a 0.3 m y de 0.0 a cada 0.1 m hasta profundidades de 1 m y 3 m. Se recolectaron 50 muestras de agua freática, además se obtuvieron extractos de saturación (1: θsat) de las distintas muestras de suelos. A los extractos de suelo y aguas freáticas, se les determinó el pH, CE, cationes y aniones mayoritarios, se calculó el parámetro relación de adsorción de sodio en su formulación original y ajustada (RAS or , RAS aj ) y el porciento de sodio intercambiable (PSI). El pH, CE y RAS or del agua freática estuvieron dentro de los intervalos de 6.94-8.37, 199-4660 µS cm-1 y 0.16-32.30 (mmolc L-1)1/2, mientras que en los extractos de saturación entre 4.81-8.58, 0.08-72.4 dS m-1 y 0.11-33.09 (mmolc L-1)1/2 respectivamente. Los problemas de salinidad en la zona de estudio están estrechamente relacionados con la intrusión de sales provenientes del sistema marino.

Resumen En este trabajo se optimizó un ELISA, mediante la aplicación de diseños factoriales completos de experimentos, para detectar anticuerpos IgA anti-RBD del SARS-CoV-2 en leche materna de puérperas que recibieron durante el embarazo tres dosis de la vacuna anti-COVID-19 Abdala, basada en la plataforma de subunidades proteicas. A partir de un protocolo preliminar no optimizado, se evaluaron las interacciones entre los factores y niveles en el paso de recubrimiento de la placa con el antígeno RBD y en el paso de reacción del antígeno con los anticuerpos de la leche; se determinó además el factor dilución para aplicar el conjugado enzimático en el ensayo. Se estableció la combinación óptima de factores y niveles para conformar el protocolo optimizado del ELISA, con el que se logró incrementar 4,67 veces la relación señal/ruido del ensayo respecto al no optimizado. El nuevo protocolo garantizará la detección de anticuerpos IgA anti-RBD del SARS-CoV-2 en las muestras de leche materna con bajo contenido de estos anticuerpos y que probablemente tuvieran una señal de absorbancia cercana al blanco del ensayo si se aplicara el ELISA no optimizado.

Abstract In this work, an ELISA was optimized through the application of full factorial designs of experiments, to detect IgA anti-RBD antibodies to SARS-CoV-2 in breast milk of puerperal women who received, during pregnancy, three doses of the Abdala anti-COVID-19 vaccine, created on the protein subunit platform. Based on a preliminary non-optimized protocol, the interactions between the factors and levels, at the step of RBD antigen coating of the plate and in the reaction of the antigen with the breast milk antibodies, were evaluated; the dilution factor to apply the enzyme conjugate in the assay was also determined. The optimized ELISA protocol was established with the best combination of factors and levels, with which it was possible to increase the signal to noise ratio of the assay by 4.67 times compared to the non-optimized one. The new protocol will guarantee the detection of SARS-CoV-2 IgA anti-RBD antibodies in breast milk samples with a low content of these antibodies and that would probably have an absorbance signal close to the assay blank if the non-optimized ELISA were applied.

Resumen Antecedentes: El reemplazo valvular por prótesis mecánicas o biológicas implica riesgo de tromboembolismo y complicaciones hemorrágicas. Objetivo: Determinar las complicaciones relacionadas con la terapia de anticoagulación complementaria y la probabilidad de riesgo en pacientes portadores de prótesis valvulares del corazón. Métodos: Se estudiaron 163 pacientes entre 2002 y 2016, portadores de prótesis mecánicas y biológicas, quienes recibieron antagonistas de la vitamina K posterior al egreso hospitalario. La terapia de anticoagulación se categorizó en óptima y no óptima conforme a los valores de INR previos a las complicaciones. Fueron excluidos los pacientes con comorbilidades y otros factores de riesgo de trombosis y/o sangrado. Resultados: a 68.7 % de los pacientes se les colocó prótesis mecánica y a 31.3 %, biológica (p ≤ 0.001); 25.2 % presentó las complicaciones motivo de estudio (p ≤ 0.001), hemorrágicas en 48.8 %, tromboembólicas en 26.8 % y de ambos tipos en 24.4 % (riesgo relativo = 4.229); a 95.1 % de los pacientes con complicaciones se les colocó prótesis mecánica y a 4.9 %, biológica (p = 0.005); 49.7 % presentó INR no óptimo (p ≤ 0.001). Conclusiones: Ante riesgo alto de complicaciones tromboembólicas y hemorrágicas, la elección de las prótesis valvulares, la prevención y el seguimiento son prioridades, principalmente en quienes requieren terapia de anticoagulación.

Abstract Background: Heart valve replacement surgery with mechanical or biological prostheses entails a risk of thromboembolism and bleeding complications. Objective: To determine the complications related to complementary anticoagulation therapy and the probability of risk. Methods: One-hundred and sixty-three patients who underwent heart valve replacement between 2002 and 2016 with either mechanical or biological prostheses, and who received vitamin K antagonists after hospital discharge, were studied. Anticoagulation therapy was categorized into optimal and non-optimal according to INR values prior to the development of complications. Patients with comorbidities and other risk factors for thrombosis and/or bleeding were excluded. Results: In total, 68.7 % of patients received mechanical prostheses, and 31.3 %, biological prostheses (p ≤ 0.001); 25.2 % experienced the complications that motivated the study (p ≤ 0.001), which were hemorrhagic in 48.8 %, thromboembolic in 26.8 %, and of both types in 24.4 % (relative risk = 4.229). Among the patients with complications, 95.1 % received mechanical prostheses, and 4.9 %, biological (p = 0.005); non-optimal INR was identified in 49.7 % (p ≤ 0.001). Conclusions: Given the high risk of thromboembolic and hemorrhagic complications, valve prostheses must be carefully chosen, and care priorities should include prevention and follow-up, especially in those patients who require anticoagulation therapy.

ABSTRACT Aquaculture combines techniques for breeding and harvesting aquatic organisms used in shrimp production. It is important as a source of income and for generating foreign exchange in the regions where it is practiced. However, the timely detection of diseases continues to be a great challenge for aquaculture and fisheries production. In recent years, Enterocytozoon hepatopenaei (EHP) has emerged as a major pathogen of the Pacific white shrimp Penaeus vannamei in many Asian countries (Vietnam, China, Indonesia, Malaysia, Thailand, India, and Korea). In Latin America, only in Venezuela, and to date, there is no report of its presence in Mexico. It is transmitted directly from shrimp to shrimp by oral or fecal means, cannibalism, or exposure to contaminated water. Hepatopancreatic microsporidiosis (HPM) is mainly associated with stunted growth and severe infections that can cause a poor production cycle, mortality, and problems in larva-producing laboratories. This review aims to overview the main microsporidian parasites and diseases found in white shrimp, including the clinical signs, control and prevention measures for EHP infection, and the detection of HPM using different techniques. In order to offer timely detection tools, different techniques are available for the detection and study of microsporidia. Such as optical microscopy, transmission electron microscopy, and histology; however, for diagnostic purposes, molecular methods are preferred due to their sensitivity, specificity, and short-time analysis. Our review suggests that constant monitoring in shrimp hatcheries and farms is essential to avoid the entry or transference of infected organisms, affecting shrimp production and the ideal development of healthy shrimp.

Resumen Las hepáticas se distribuyen de forma heterogénea en su hábitat, pues dependen de condiciones micro ambientales particulares para su establecimiento. En este trabajo se presenta un listado florístico y se estima la riqueza y semejanza en la composición de especies de hepáticas epifitas del bosque mesófilo de montaña (BMM) de Hidalgo, a lo largo de un gradiente de altitud. Además, se integra información sobre sus patrones de distribución geográfica. Las muestras se tomaron en tres municipios con BMM del estado de Hidalgo en un intervalo de altitud de 1345-2019 m. En cada municipio se colocaron dos parcelas de muestreo de 0.1 ha en los extremos del gradiente altitudinal. Dentro de cada parcela se seleccionaron 10 árboles y en cada uno de ellos se colocaron tres micro parcelas de 10×10 cm sobre su corteza para estimar la riqueza de especies. Se determinaron nueve familias, 17 géneros, 29 especies y dos variedades de hepáticas. Las familias Lejeuneaceae y Plagiochilaceae presentaron el mayor número de especies. Los géneros Lejeunea Lib. y Plagiochila (Dumort.) Dumort. fueron los más diversos, con siete y cinco especies, respectivamente. La composición, riqueza y distribución de las especies fue variable a lo largo del gradiente analizado; la distribución geográfica de la mayoría de las especies (55 %), se restringe a la región neotropical.

Abstract Liverworts are distributed heterogeneously in their habitat, as they depend on particular micro environmental conditions for their establishment. In this work, a floristic list is presented and the richness, and similarity in the species composition of epiphytic liverworts from Hidalgo´s cloud forest (CF) is estimated, along an elevation gradient. In addition, information on their geographic distribution patterns is integrated. The samples were taken in three municipalities with CF of the Hidalgo state in an altitude interval of 1345-2019 m. On each site two sampling plots of 0.1 ha were placed at the ends of the altitudinal gradient. Within each plot, 10 trees were selected and in each of three micro plots of 10×10 cm were placed on its cortex to estimate the species richness. Nine families, 17 genera, 29 species and two varieties of liver were determined. Lejeuneaceae and Plagiochilaceae families presented the largest number of species. The Lejeunea Lib. and Plagiochila (Dumort.) Dumort were the most diverse genera, with seven and five species, respectively. The composition and richness of species were variables along the analyzed gradient; the geographic distribution of most of the species (55%) is restricted to the neotropical region.

Abstract Objective: We evaluated whether cholesteryl ester transfer protein (CETP) gene polymorphisms are associated with the presence of coronary artery disease (CAD) and/or restenosis in patients with coronary stent. Methods: Two polymorphisms of the CETP gene [−971 A/G (rs4783961), and Taq1B A/G (rs708272)] were genotyped by 5'exonuclease TaqMan assays in 219 patients with CAD (66 patients with restenosis and 153 without restenosis) and 607 control individuals. Results: The distribution of polymorphisms was similar in patients with and without restenosis. However, when the whole group of patients (with and without restenosis) was compared to healthy controls, under dominant model, the G allele of the Taq1B A/G polymorphism was associated with increased risk of CAD (odds ratio [OR] = 1.48, pCDom = 0.032). In the same way, under codominant, dominant, and additive models, the A allele of the −971 A/G polymorphisms was associated with an increased risk of developing CAD (OR = 2.03, pCCo-dom = 0.022, OR = 1.83, pCDom = 0.008, and OR = 1.39, pCAdd = 0.011, respectively). In addition, the linkage disequilibrium showed that the “AG” haplotype was associated with increased risk of developing CAD (OR = 1.28, p = 0.03). Conclusion: This study demonstrates that CETP Taq1B A/G and CETP −971 A/G polymorphisms are associated with an increased risk of developing CAD, but no association with restenosis was observed.

Resumen Objetivo: Evaluamos si los polimorfismos del gen CETP están asociados con la presencia de enfermedad arterial coronaria (EAC) y/o restenosis en pacientes con stent coronario. Métodos: En este estudio se genotiparon dos polimorfismos del gen CETP [−971 A/G (rs4783961) y Taq1B A/G (rs708272)] mediante ensayos de 5'exonucleasa TaqMan en 219 pacientes con EAC (66 pacientes con restenosis y 153 sin restenosis), y 607 individuos de control. Resultados: La distribución de polimorfismos fue similar en pacientes con y sin restenosis. Sin embargo, cuando se comparó todo el grupo de pacientes (con y sin restenosis) con controles sanos, bajo el modelo dominante el alelo G del polimorfismo Taq1B A/G se asocia con un mayor riesgo de EAC (OR = 1.48, pCDom = 0.032). De la misma manera, bajo los modelos co-dominante, dominante y aditivo, el alelo A de los polimorfismos −971 A/G se asocia con un mayor riesgo de desarrollar EAC (OR = 2.03, pCCo-dom = 0.022, OR = 1.83, pCDom = 0,008 y OR = 1.39, pCAdd = 0.011, respectivamente). Adicionalmente, el desequilibrio de ligamiento mostró que el haplotipo “AG” se asocia con un mayor riesgo de desarrollar EAC (OR = 1.28, p = 0.03). Conclusión: En resumen, este estudio demuestra que los polimorfismos CETP Taq1B A/G y CETP −971 A/G están asociados con un mayor riesgo de desarrollar CAD, pero no se observó asociación con restenosis.

ABSTRACT Background: Information is needed on the safety and efficacy of direct discharge from the emergency department (ED) of patients with COVID-19 pneumonia. Objectives: The objectives of the study were to study the variables associated with discharge from the ED in patients presenting with COVID-19 pneumonia, and study ED revisits related to COVID-19 at 30 days (EDR30d). Methods: Multicenter study of the SIESTA cohort including 1198 randomly selected COVID patients in 61 EDs of Spanish medical centers from March 1, 2020, to April 30, 2020. We collected baseline and related characteristics of the acute episode and calculated the adjusted odds ratios (aOR) for ED discharge. In addition, we analyzed the variables related to EDR30d in discharged patients. Results: We analyzed 859 patients presenting with COVID-19 pneumonia, 84 (9.8%) of whom were discharged from the ED. The variables independently associated with discharge were being a woman (aOR 1.890; 95%CI 1.176-3.037), age < 60 years (aOR 2.324; 95%CI 1.353-3.990), and lymphocyte count > 1200/mm3 (aOR 4.667; 95%CI 1.045-20.839). The EDR30d of the ED discharged group was 40.0%, being lower in women (aOR 0.368; 95%CI 0.142-0.953). A total of 130 hospitalized patients died (16.8%) as did two in the group discharged from the ED (2.4%) (OR 0.121; 95%CI 0.029-0.498). Conclusion: Discharge from the ED in patients with COVID-19 pneumonia was infrequent and was associated with few variables of the episode. The EDR30d was high, albeit with a low mortality.

Abstract: In recent decades, the growing obesity epidemic in Mexico has become one of the most important public health challenges faced by the country. With support from the World Obesity Federation, we formed a working group in 2021 to identify and summarize priority actions that Mexico can take to face this epidemic. More than 1 000 health professionals joined the development and discussion process. Recommendations from previously published, high-level documents and guidelines were taken into account. In commemoration of World Obesity Day 2022, this statement is presented as input for health care professionals to develop actions to address obesity. The statement includes 10 recommendations that include population-level and individual-level actions. It emphasizes the importance of social participation, comprehensive interventions with a person- centered perspective, planetary sustainability, on improving education and communication campaigns, as well as fostering a built environment that promotes active living, and shielding prevention and control efforts from conflicts of interest. The statement calls for obesity to be treated seriously, based on scientific evidence, in a timely and comprehensive manner, employing a life-course and ethical approach that does not perpetuate weight stigma in society.

Abstract Introduction: Severe Dendroctonus spp. infestations are reported in North and Central America. Dendroctonus mexicanus Hopkins and Dendroctonus frontalis Zimmermann are recognized as forest pests and are common in the state of Michoacán, Mexico. Objective: To model current and future (2015-2039) spatial distribution of risk of D. mexicanus and D. frontalis infestation in forests of Michoacán, Mexico. Materials and methods: Multicriteria evaluation techniques, including the analytic hierarchy process and fuzzy membership functions, were combined with climate and biophysical variables to obtain forest infestation risk maps for D. mexicanus and D. frontalis under current and future climate scenarios. Results and discussion: Climate, fire, tree density and topography were identified as relevant criteria influencing bark beetle outbreaks. The maximum risk value estimated for D. mexicanus was 0.78 and 0.83 for the current and future scenarios, respectively; for D. frontalis these values correspond to 0.84 and 0.85, respectively. In terms of area, high risk of infestation by D. mexicanus increased from 3.9 % (current scenario) to 5.0 % (future scenario); for D. frontalis it decreased from 10.8 % to 9.6 %. The very high-risk value remained constant (0.35 %) for both species and scenarios. Conclusions: Forests of the Transversal Volcanic Belt (in the northeastern part of Michoacán) have the highest risk of bark beetle infestation in the two modeled scenarios.

Resumen Introducción: En Norteamérica y Centroamérica se reportan infestaciones fuertes por Dendroctonus spp. En México, Dendroctonus mexicanus Hopkins y Dendroctonus frontalis Zimmermann son reconocidos como plagas forestales y son comunes en el estado de Michoacán. Objetivo: Modelar la distribución espacial actual y futura (2015-2039) del riesgo de brotes de D. mexicanus y D. frontalis en los bosques del estado de Michoacán, México. Materiales y métodos: Se conjuntaron técnicas de evaluación multicriterio, incluyendo el proceso de análisis jerárquico y funciones de membresía borrosa, con variables climáticas y biofísicas para obtener mapas del riesgo de infestación de bosques por D. mexicanus y D. frontalis bajo los escenarios climáticos actual y futuro. Resultados y discusión: El clima, incendio, densidad arbórea y topografía se identificaron como criterios relevantes que inciden en los brotes de descortezadores. El valor máximo de riesgo estimado para D. mexicanus fue 0.78 y 0.83 para el escenario actual y futuro, respectivamente; para D. frontalis estos valores corresponden a 0.84 y 0.85, respectivamente. En términos de superficie, el riesgo alto de infestación por D. mexicanus incrementó de 3.9 % (escenario actual) a 5.0 % (futuro); para D. frontalis disminuyó de 10.8 % a 9.6 %. El valor de riesgo muy alto permaneció constante (0.35 %) para ambas especies y escenarios. Conclusiones: En los dos escenarios modelados, los bosques de la Faja Volcánica Transversal (en la parte noreste de Michoacán) presentan el mayor riesgo de infestación por descortezadores.

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.

Abstract: En Es | Text: En Es | PDF: En | PDF: Es

Abstract Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.

Abstract: Es En | Text: Es En | PDF: Es | PDF: En

Resumen Las plaquetas tienen un papel central en diferentes escenarios fisiológicos, incluyendo la hemostasia; se unen unas con otras en la agregación plaquetaria, lo cual permite formar un coágulo plaquetario. Para que la agregación sea apropiada se requiere del complejo glicoproteico IIb/IIIa (GPIIb/IIIa) en la superficie plaquetaria. Toda alteración funcional plaquetaria, hereditaria o adquirida, impide la formación adecuada del coágulo y se manifiesta como hemorragia. Las enfermedades plaquetarias hereditarias son raras y, hasta recientemente, fueron ignoradas. Una de las más reconocidas y estudiadas es la trombastenia de Glanzmann (TG), entidad en la cual el número de plaquetas puede ser normal pero la función está alterada. Es un padecimiento autosómico y recesivo que causa hemorragia de diferente intensidad toda la vida y en la cual el problema radica en precisamente en la GPIIb/IIIa. Las hemorragias son típicamente mucocutáneas: equimosis, púrpura, epistaxis, gingivorragia; menos frecuentes son la hemorragia gastrointestinal, hemartrosis o en sistema nervioso central. La hiperpolimenorrea es común en las mujeres y llega a ser tan importante que amerita transfusiones en la menarca. La TG afecta a todos los grupos étnicos y su prevalencia varía entre 1/40,000 y 1/400,000. A pesar de esta información acerca de la TG en el mundo, hay pocas guías o recomendaciones basadas en la opinión de expertos y experiencias unicéntricas. En México la TG es rara y no se cuenta con una recomendación general para su diagnóstico y tratamiento. El objetivo de este documento fue establecer un consenso y hacer sugerencias generales para su diagnóstico y tratamiento.

Abstract Platelets have a central role in several physiological scenarios including hemostasis. Platelets bind each other during platelet aggregation allowing the proper formation of the clot; to be appropriate, platelet aggregation requires the glycoproteic complex IIb/IIIa (GPIIb/IIIa). Every platelet function abnormality both, congenital or acquired, impedes clot formation and favors bleeding episodes. Hereditary platelet abnormalities are rare and, until recently, they were almost ignored. Among these disorders, Glanzmann Thrombasthenia (GT) is a widely recognized abnormality in which platelet counts may be normal, but their function is affected. GT is an autosomal, recessive disease that causes life-long bleeding of different intensity. Main biochemical abnormality resides in GPIIb/IIIa. Bleeding is typically mucocutaneous: easy bruising, purpura, and nose and gum bleeds; less frequently are gastrointestinal bleeds, hemarthrosis, or intracranial. Menorrhagia and hyperpolymenorrhea are common findings in in women and may be the cause of anemia requiring blood transfusions at fertile age. GT affects all ethnic groups and its prevalence ranges between 1/40,000 to 1/400,000. Despite this worldwide information regarding GT, only a few guidelines and recommendations have been published, most of them based on expert opinions. In Mexico, GT is rare and there is not a general recommendation regarding its diagnosis and treatment. The aim of this document was to establish a consensus to suggest a general guideline for the diagnosis and treatment of GT in Mexico.

Abstract: En Es | Text: En Es | PDF: En | PDF: Es

Summary: An overview of current Mexican legislation regarding soil restoration and updating needs is made through the analysis of three case studies located in the southeastern México: a) soil affected by spillage of congenital waters (Zone 1), b) soil contaminated by hydrocarbons (Zone 2) and, c) a site adjacent to urban infrastructure (Zone 3). It was performed a comparative analysis of the soils conditions in the short and long term after the anthropogenic impact and restoration process that were carried out in each studied location. It was found that important properties of the soils do not recover after the weathering process, for instance in Zone 1, DR and DA as well as %Po did not reach equivalent values to the control sample and the soil texture is different even after a long recovery period. For Zone 2, it was detected important variations in the concentration of Ca, Na and K in both the impacted and recovered soils which affect the growth of plantations. In Zone 3, there were found significative differences in DA, %Po; %L, %R, %MO and CEC parameters. The current normative considers general aspects, but does not contemplate the actual site situation, there is an information gap due to this, although it was observed achievement of physical and chemical properties for the recovery soil use in each site, it was also noticed that the evaluations do not consider if these properties can change over time due to weather conditions, therefore, they could influence the success of each restoration process in the long term. The information generated can be used to make decisions about government rescue programs for the primary sector or as a starting point in the implementation of Environmental Bases Lines (LBA) for the hydrocarbon sector.

Resumen: Se realizó una visión general de la legislación mexicana vigente en materia de restauración del suelo y de las necesidades de actualización a través del análisis de tres estudios de caso ubicados en el sureste de este país: a) suelo afectado por derrames de aguas congénitas (Zona 1), b) suelo contaminado por hidrocarburos (Zona 2) y c) un sitio adyacente a infraestructura urbana (Zona 3). Se realizó un análisis comparativo a corto y largo plazo de las condiciones de los suelos después del impacto antropogénico y el proceso de restauración que se llevó a cabo en cada caso de estudio. Se encontró que propiedades importantes de los suelos no se recuperaron después del proceso de intemperizado. Por ejemplo, en la Zona 1, DA, DR y %Po no alcanzaron valores equivalentes a los del suelo testigo aun después de un tiempo prolongado de recuperación. En la Zona 2, se detectaron variaciones importantes en las concentraciones de Ca, Na y K tanto en el suelo impactado como en el recuperado, lo cual afecta el crecimiento de plantaciones. En la Zona 3, se encontraron diferencias significativas en parámetros como: DA, %Po; %L, %R, %MO y CEC. Se encontró una brecha de información en la normativa actual que considera aspectos generales, pero no considera la situación real del sitio, aunque se observó el cambio de propiedades físicas y químicas para el uso de recuperación del suelo en cada sitio, también se observó que las evaluaciones no consideran si estas propiedades pueden cambiar con el tiempo debido a las condiciones climáticas y por lo tanto podrían influir en el éxito de cada proceso de restauración a largo plazo. La información generada puede ser utilizada para tomar decisiones sobre los programas de rescate del gobierno para el sector primario o como punto de partida en la implementación de Líneas Bases Ambientales del sector de hidrocarburos.
