ABSTRACT Objective: Based on hypothetical hypothyroidism and nonthyroidal illness syndrome (NTIS) gene expression similarities, we decided to compare the patterns of expression of both as models of NTIS. The concordant profile between them may enlighten new biomarkers for NTIS challenging scenarios. Materials and methods: We used Ion Proton System next-generation sequencing to build the hypothyroidism transcriptome. We selected two databanks in GEO2 platform datasets to find the differentially expressed genes (DEGs) in adults and children with sepsis. The ROC curve was constructed to calculate the area under the curve (AUC). The AUC, chi-square, sensitivity, specificity, accuracy, kappa and likelihood were calculated. We performed Cox regression and Kaplan-Meier analyses for the survival analysis. Results: Concerning hypothyroidism DEGs, 70.42% were shared with sepsis survivors and 61.94% with sepsis nonsurvivors. Some of them were mitochondrial gene types (mitGenes), and 95 and 88 were related to sepsis survivors and nonsurvivors, respectively. BLOC1S1, ROMO1, SLIRP and TIMM8B mitGenes showed the capability to distinguish sepsis survivors and nonsurvivors. Conclusion: We matched our hypothyroidism DEGs with those in adults and children with sepsis. Additionally, we observed different patterns of hypothyroid-related genes among sepsis survivors and nonsurvivors. Finally, we demonstrated that ROMO1, SLIRP and TIMM8B could be predictive biomarkers in children's sepsis.

Abstract Introduction Viral infections, such as infection by SARS-CoV-2, can affect gait biomechanics, but this effect can be overlapped by consequences of critical illness and time in intensive care unit. Objective To report biomechanical alterations during the clinical evolution of a post-COVID-19 patient who presented severe motor impairment after intensive care. Methods Data was collected from the patient’s chart at José Silveira Foundation and previous medical reports from the hospitalization period. The patient was wheelchair bound, with physiotherapy twice a week, and by the end of 1-year follow-up was able to walk independently. Three-dimensional gait analysis with kinetics and electromyography were conducted at three time points. Results All spatiotemporal gait parameters, kinematic, kinetic and electromyographic data was importantly altered when compared to the normal range of values. With physiotherapy, gait quality indicators showed important improvements and all muscles presented a significant increase in the magnitude of the electromyographic signal (at least a two-fold increase). Trunk kinematic alterations decreased significantly during this period. Kinetic and kinematic changes perceived in the hips, knees and ankles showed approximation to the expected pattern, however still without normalizing, and patient's muscle coordination improved over time. Conclusion This report has great clinical importance, as it describes, using an instrumented gait laboratory, the evolution of a patient with severe motor impairment post intensive care due to COVID-19, a condition in lack of description in the literature, which will help health professionals in the planning of rehabilitation strategies.

Resumo Introdução Infecções virais, como a infecção por SARS-CoV-2, podem afetar a biomecânica da marcha, mas esse efeito pode ser sobreposto por consequências de doença crítica e tempo em unidade de terapia intensiva. Objetivo Relatar as alterações biomecânicas durante a evolução clínica de um paciente pós-COVID-19 que apresentou comprometimento motor severo após terapia intensiva. Métodos Os dados foram coletados a partir do prontuário do paciente na Fundação José Silveira e dos relatórios médicos anteriores referentes ao período de inter-nação. O paciente estava em cadeira de rodas, com fisioterapia duas vezes por semana, e ao final de 1 ano de acompanhamento era capaz de deambular de forma independente. A análise tridimensional da marcha com cinética e eletromiografia foi realizada em três momentos. Resultados Todos os parâmetros espaço-temporais da marcha, dados cinemáticos, cinéticos e eletromiográficos estavam significativamente alterados quando comparados com a faixa normal de valores. Com a fisioterapia, os indicadores de qualidade da marcha apresentaram melhorias importantes e todos os músculos apresentaram um aumento significativo na magnitude do sinal eletromiográfico (aumento de pelo menos duas vezes). As alterações cinemáticas do tronco diminuíram significativamente neste período. As alterações cinéticas e cinemáticas percebidas nos quadris, joelhos e tornozelos mostraram aproximação do padrão esperado, porém ainda sem normalização, e a coordenação muscular do paciente melhorou com o passar do tempo. Conclusão Este relato é de grande importância clínica, pois descreve, por meio de um laboratório de marcha instrumentado, a evolução de um paciente com comprometimento motor severo após terapia intensiva por COVID-19, quadro pouco descrito na literatura, o que ajudará profissionais de saúde no planejamento de estratégias de reabilitação.

Resumen: La calidad del forraje se determina mediante un análisis bromatológico, el cual mide variables como: peso seco (PS), proteína bruta (PB), fibra detergente ácido (FDA), fibra detergente neutro (FDN) y cenizas. La calidad es importante, ya que interviene en aspectos relacionados con la nutrición animal y su productividad; y en efectos ambientales como la generación de metano (CH4). Este estudio tuvo como objetivo evaluar el efecto del agua potable y dos soluciones nutritivas, con diferente relación nitrato/amonio (NO3 -/NH3 +); en el peso fresco (PF) y la calidad bromatológica del forraje verde hidropónico (FVH) de avena (Avena sativa) y cebada (Hordeum vulgare), muestreado a los 5, 10 15, 20, 25 y 30 días después de la siembra. Se midieron las variables PF, PS, PB, FDN, FDA y cenizas. Para el análisis estadístico se utilizó un modelo factorial 3×2 (tres soluciones nutritivas y dos especies de semilla) con medidas repetidas en el tiempo; y la comparación de medias de Tukey (P ≤ 0.05). De acuerdo con el análisis de varianza (P ≤ 0.05), se observó que: i) el tiempo tuvo un efecto significativo en todas las variables estudiadas; ii) las soluciones nutritivas solo afectaron a la PB, y iii) la especie utilizada tuvo efecto en la PB, FDN, FDA y cenizas. Acorde con la comparación de medias se observó que: i) existió un incremento en el valor de todas las variables conforme avanzó el tiempo de muestreo; ii) el porcentaje de PB fue mayor con las soluciones nutritivas que con el agua potable, pero no se observó diferencia entre las soluciones; y iii) el FVH de avena tuvo mayores valores de PB, FDN, FDA y cenizas; por lo cual se concluyó que dicho FVH posee mejores características nutritivas para el ganado que el FVH de cebada.

Summary: Forage quality is important since it intervenes in aspects related to animal nutrition and productivity and in environmental effects such as methane generation (CH4). Forage quality is determined by a bromatological analysis, which measures variables such as: dry weight (DW), crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF) and ash. Thus, the objective of this study is to evaluate the effects of drinking water and two nutritional solutions with different nitrate/ammonium (NO3 -/NH3 +) ratios on fresh weight (FW) and bromatological quality of hydroponic green forage (HGF). Oats (Avena sativa) and barley (Hordeum vulgare) were sampled at 5, 10, 15, 20, 25 and 30 days after planting. The variables FW, DW, CP, NDF, ADF, and ash were measured. For the statistical analysis, a 3×2 factorial model (three nutritive solutions and two seed species) was used with repeated measurements over time and Tukey’s comparison of means (P ≤ 0.05). According to the analysis of variance (P ≤ 0.05) (i) time had significant effects on all the variables studied; (ii) nutrient solutions only affected CP; and (iii) the species used had an effect on CP, NDF, ADF and ash. Consistent with the comparison of means, (i) an increase in value of all variables was observed as sampling time progressed; (ii) CP percentage was higher with nutritive solutions than with drinking water, but no difference was observed between solutions; and (iii) hydroponically-grown (HGF) oats had higher CP, NDF, ADF and ash values. To conclude, HGF oats has better nutritional characteristics for livestock than HGF barley.

Abstract: Introduction: Acute myocardial infarction has a high prevalence and possibility of death if timely care is not given. It is possible that treatment could be delayed during a health crisis such as the COVID-19 pandemic. Objective: The objective of this study was to evaluate the impact of the COVID-19 pandemic on the function of the infarction code in the High Specialty Medical Unit of our institution. The medical indicators of acute coronary ischemic syndrome with ST-segment elevation were compared at two times: before the COVID-19 pandemic and during it. Material and methods: An ambispective, analytical, comparative cohort study was conducted, comparing the periods of February-September 2019 and February-September 2020, in the High Specialty Medical Unit, Centro Médico del Bajío number 1, Instituto Mexicano del Seguro Social, Leon, Guanajuato, Mexico. All patients older than 18 years with clinical, electrocardiographic, and enzymatic data of acute coronary ischemic syndrome, accepted in the medical network as infarction code registered in the National Registry of Acute Coronary Ischemic Syndromes (RENASCA) electronic case report form were included in the study. Results: The independent samples t-test was used to determine the impact of the infarction code initiative based on the reperfusion therapies performed, the door-to-needle, the door-to-balloon time, and the ischemia time. There was a significant difference in the reperfusion strategy, with greater thrombolysis during the COVID-19 pandemic (57.4% versus 72.6%, odds ratio [OR] 1.97, 95% confidence interval [CI] 0.49-0.82, p < 0.001), as well as reperfusion criteria (21.03% versus 35.37%, OR 2.05, 95% CI 0.53-0.80, p < 0.0001). Mortality was not different between the time periods. Conclusions: The COVID-19 pandemic has not impacted operation of the infarction code in the High Specialty Medical Unit Centro Médico del Bajío number 1 because the medical indicators of acute coronary ischemic syndrome with ST-segment elevation did not change.

ABSTRACT Currently there is a wide range of multivariate techniques, which are used in different areas of research. The present work focuses on the Principal Components Method and aims to establish a set of methodological criteria for the processing and interpretation of results in the use of this technique on mathematical-statistical bases. An example associated with post-harvest studies of the pineapple (variety Cayena Lisa) is developed. A sequence of steps is proposed that includes: previous analysis of correlation between variables, determination of the number of components to be selected (compromise between the different criteria), weight of variables in each component, biological interpretation and graphs that validate the results obtained in reference to components and individuals. The study had the variables: weight loss in g (PP), firmness, color index (IC), soluble solids content (SSC) and pH. The variables were grouped into two components that explain 88.36% of the variation in the data. A positive relationship was observed among PP, SSC and pH and the negative relationship of firmness with these variables. It is shown that the highest PP and pH are reached from the sixth day and the highest firmness, in the first two days, aspects to take into account in making timely decisions for storage, transportation and marketing. It is concluded that the use of multivariate techniques and, particularly, the analysis of principal components constitutes an efficient and non-destructive way in monitoring the quality of fruits in storage.

RESUMEN En la actualidad existe una amplia gama de técnicas multivariadas, que se utilizan en las diferentes áreas de investigación. El presente trabajo se centra en el Método de Componentes Principales y tiene como objetivo establecer sobre bases matemático-estadísticas un conjunto de criterios metodológicos para el procesamiento e interpretación de resultado con el empleo de dicha técnica. Se desarrolla un ejemplo asociado a estudios pos cosecha de la Piña (variedad Cayena Lisa). Se proponen una secuencia de pasos que incluye: análisis previo de correlación entre variables, determinación de números de componentes a seleccionar (compromiso entre los diferentes criterios), peso de variables en cada componente, interpretación biológica y gráficos que validan los resultados obtenidos en sentido de las componentes e individuos. El estudio contó con las variables: pérdida de peso en g (PP), firmeza, índice de color (IC), contenido de solidos solubles (SSC) y PH. Las variables se agruparon en dos componentes que explican el 88,36 % de la variación de los datos. Se observó una relación positiva entre PP, SSC y PH y la relación negativa de la firmeza con estas variables, se muestra que la mayor PP y PH se alcanza a partir del sexto día, y la mayor firmeza en los dos primeros días, aspectos a tener en cuenta en la toma de decisiones oportunas para el almacenaje, trasporte y comercialización. Se concluye que el empleo de técnicas multivariadas y en particular el análisis de componentes principales constituye una vía eficiente y no destructiva en el monitoreo de la calidad de frutos en almacenamiento.

RESUMO O DC de Neuroimunologia da ABN e o BCTRIMS trazem, nesse documento, as recomendações sobre vacinação da população com doenças desmielinizantes do sistema nervoso central (SNC) contra infecções em geral e contra o coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2), causador da COVID-19. Destaca-se a gravidade do atual momento frente ao avanço da COVID-19 em nosso País, o que torna mais evidente e importante a criação de guia de referência para orientação aos médicos, pacientes e autoridades de saúde pública quanto à vacinação, meio efetivo e seguro no controle de determinadas doenças infecciosa. O DCNI/ABN e o BCTRIMS recomendam que os pacientes com doenças desmielinizantes do SNC (ex., EM e NMOSD) sejam constantemente monitorados, quanto a atualização do seu calendário vacinal, especialmente, no início ou antes da mudança do tratamento com uma droga modificadora de doença (DMD). É importante também salientar que as vacinas são seguras e os médicos devem estimular o seu uso em todos os pacientes. Evidentemente, deve ser dada especial atenção às vacinas com vírus vivos atenuados. Por fim, é importante que os médicos verifiquem qual DMD o paciente está em uso e quando foi feita a sua última dose, pois cada fármaco pode interagir de forma diferente com a indução da resposta imune.

ABSTRACT The Scientific Department of Neuroimmunology of the Brazilian Academy of Neurology (DCNI/ABN) and Brazilian Committee for Treatment and Research in Multiple Sclerosis and Neuroimmunological Diseases (BCTRIMS) provide recommendations in this document for vaccination of the population with demyelinating diseases of the central nervous system (CNS) against infections in general and against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19. We emphasize the seriousness of the current situation in view of the spread of COVID-19 in our country. Therefore, reference guides on vaccination for clinicians, patients, and public health authorities are particularly important to prevent some infectious diseases. The DCNI/ABN and BCTRIMS recommend that patients with CNS demyelinating diseases (e.g., MS and NMOSD) be continually monitored for updates to their vaccination schedule, especially at the beginning or before a change in treatment with a disease modifying drug (DMD). It is also important to note that vaccines are safe, and physicians should encourage their use in all patients. Clearly, special care should be taken when live attenuated viruses are involved. Finally, it is important for physicians to verify which DMD the patient is receiving and when the last dose was taken, as each drug may affect the induction of immune response differently.

Abstract The population of creole chickens in small-scale farms is remarkably diverse and part of the poultry genetic reservoir in Mexico. Furthermore, this population represents a vital protein source for rural families. The genetic variability of creole chicken populations in the central region of Oaxaca was determined in blood samples collected from 109 creole chickens belonging to 17 populations and 30 Plymouth Rock chickens (control group). Ten microsatellite markers were used to detect a total of 109 alleles, with an average of 10.9 ± 3.1 alleles per locus. The observed heterozygosity (Ho) ranged from 0.575 (San Lucas) to 0.750 (San Antonio 2); the expected heterozygosity ranged from 0.625 (Control) to 0.733 (Huixtepec 2). Overall, it was observed an increase in the number of heterozygotes, evidenced by a global-level inbreeding (FIT) of 0.042; the FST population differentiation index was moderate (0.059), and the inbreeding of individuals within populations (FIS) was negative (-0.017), which indicates an excess of heterozygotes at that level. Cluster analysis grouped the Nazareno, ITVO, San Lucas, and San Antonio populations, indicating that these creole chicken populations are isolated and genetically differentiated in some characteristics. This information is important to design future conservation, selection, and multiplication programs for this species at the backyard level in the central region of Oaxaca, Mexico.

Resumen Las poblaciones de gallinas criollas en explotaciones en pequeña escala poseen una gran diversidad y son parte del reservorio genético avícola en México; además, constituyen una importante fuente de proteína para las familias del medio rural. Con el propósito de conocer la variabilidad genética de poblaciones de gallinas criollas en la región central de Oaxaca, se tomaron muestras de sangre de 109 gallinas criollas, provenientes de 17 poblaciones y de 30 gallinas Plymouth Rock como testigos. Se usaron 10 marcadores de tipo microsatélites, con los que se detectó un total de 109 alelos, con 10.9 ± 3.1 alelos por locus en promedio. La heterocigosidad observada (Ho) varió de 0.575 (San Lucas) a 0.750 (San Antonino 2) y la esperada (He) de 0.625 (Testigo) a 0.733 (Huixtepec 2). A nivel general se encontró un incremento en el número de heterocigotos evidenciado por un nivel de endogamia global (FIT) de 0.042; el índice FST de diferenciación entre poblaciones fue moderado (0.059) y la endogamia de individuos dentro de poblaciones (FIS) resultó negativa (-0.017), lo que indica un exceso de heterocigotos a ese nivel. El análisis de conglomerados agrupó a las poblaciones de Nazareno, ITVO, San Lucas y San Antonio, evidenciando que son poblaciones de gallinas criollas aisladas y diferenciadas genéticamente en algunas características. Esta información es importante para diseñar futuros programas de conservación, selección y multiplicación de esta especie a nivel de traspatio en la región central de Oaxaca, México.

Abstract Multidrug resistance is a global public health problem. In 2017, in Mexico, Salmonella caused 192,771 food-borne zoonosis cases. Sonora, Hidalgo, Mexico State and Jalisco have reports of multi-resistant Salmonella strains in chicken and beef carcasses in slaughterhouses; however, the prevalence in livestock herds is unknown. From January 2012 to October 2013, 144 diarrheal stool samples were collected from bovine hatchlings from the Altos Sur region of the Jalisco State. As a result, the presence and serotype of Salmonella was determined, as well as the antibiotic resistance profile, and the genetic relationship, using PFGE. The Salmonella prevalence was 4.16 % (6/144) in feces, identifying the serotypes Anatum, Pullorum, Poona, Typhi, Gallinarum and Salmonella enterica subsp. arizonae. All the strains showed resistance to ampicillin, cephalothin, trimethoprim-sulfamethoxazole, and some of them, additionally, to amikacin, cefotaxime and/or ceftriaxone. In addition, the persistence and potential spread of two Salmonella Anatum strains was discovered in one herd. This is the first study conducted in neonate bovine in the Jalisco State, Mexico, to detect multidrug resistant Salmonella. Continuous monitoring of multi-drug resistance in animal biota for human food and ongoing training of veterinary doctors are key elements for efficient prophylaxis and antimicrobial pharmacotherapy.

Resumen La multifarmacorresistencia es un problema mundial de salud pública. En el 2017, en México, Salmonella causó 192,771 casos de zoonosis de origen alimentario. Sonora, Hidalgo, Estado de México y Jalisco tienen reportes de Salmonella multirresistente en canales de pollo y res en mataderos. Sin embargo, se desconoce la prevalencia en animales en hatos ganaderos. De enero-2012 a octubre-2013 se recolectaron 144 muestras de heces diarreicas de neonatos bovinos de la región Altos Sur del estado de Jalisco. Se determinaron los serotipos de Salmonella, el perfil de multifarmacorresistencia y el genotipo mediante PFGE. Se encontró una prevalencia del 4.16% (6/144) de Salmonella en heces, recuperándose los serotipos Anatum, Pullorum, Poona, Typhi, Gallinarum y Salmonella enterica subsp. arizonae. Todas las cepas mostraron resistencia a ampicilina, cefalotina, trimetoprim-sulfametoxazol y adicionalmente algunas a amikacina, cefotaxima y/o ceftriaxona. Se descubrió una persistencia y propagación de dos cepas de Salmonella Anatum en un hato. Este es el primer estudio realizado en bovinos recién nacidos en el estado de Jalisco, México, para la detección de Salmonella multirresistente. Es necesario el monitoreo continuo de la multi-farmacorresistencia en la biota de animales para alimento humano y una capacitación continua de médicos veterinarios para una eficiente profilaxis y farmacoterapia antimicrobiana.

Resumen Introducción: Varios estudios han informado que el polimorfismo de un solo nucleótido rs693 del gen de la apolipoproteína B se asocia con altos niveles de lípidos plasmáticos e índice de masa corporal, los cuales son factores de riesgo para enfermedades cardiovasculares. La distribución de este polimorfismo y su asociación con el fenotipo dependen del antecedente genético de cada población. La población caribeña colombiana es producto de la mezcla de tres grupos étnicos principales: africano, amerindio y caucásico. Objetivo: Evaluar la distribución del polimorfismo rs693 y su asociación con el perfil lipídico y el índice de masa corporal en una muestra de sujetos caribeños colombianos. Métodos: Fueron incluidos en este estudio 108 sujetos adultos de ambos sexos y no relacionados. Se determinaron el índice de masa corporal y el perfil lipídico; de éste se incluyó colesterol total, triglicéridos, lipoproteínas de baja densidad y lipoproteína de alta densidad. El polimorfismo rs693 se determinó mediante Reacción en Cadena de la Polimerasa del ADN genómico seguida por digestión con la enzima de restricción XbaI. Se utilizó la prueba de ji cuadrado para analizar la distribución del genotipo de rs693 y se evaluó la asociación genotipo-fenotipo a través de diferentes modelos de herencia. Resultados: Las frecuencias genotípicas para rs693 fueron CC (45.0%), TT (16.5%) y TC (38.5%). Las frecuencias alélicas fueron C (64.0%) y T (36.0%). El polimorfismo rs693 estaba en equilibrio de Hardy-Weinberg en la muestra estudiada y no presentó asociación con el perfil lipídico ni con el índice de masa corporal (p >0.05). Conclusión: No existe asociación significativa del polimorfismo rs693 con el índice de masa corporal ni con el perfil lipídico en una muestra de caribeños colombianos.

Abstract Introduction: Several studies have reported that the single nucleotide polymorphism rs693 of Apo lipoprotein B gene is associated with high levels of plasma lipids and high body mass index, which are risk factors for cardiovascular diseases. The distribution of this single nucleotide polymorphism and its association with the phenotype depend on the genetic background of each population. Objective: To evaluate the distribution of single nucleotide polymorphism rs693 and its association with lipid profile and body mass index in a sample of Colombian Caribbeans. Methods: 108 non-related adult subjects of both gender were included in this study. Body mass index and lipid profile that included total cholesterol, triglycerides, Low Density Lipoprotein and High Density Lipoprotein were determined. The single nucleotide polymorphism rs693 was determined by Polymerase Chain Reaction/Restriction Fragment Length Polymorphism from genomic DNA followed by digestion with the restriction enzyme XbaI. The chi-square test was used to analyze the genotype distribution of rs693 and the genotype-phenotype association was evaluated through different inheritance model. Results: The genotype frequencies for single nucleotide polymorphism rs693 were CC (45.0%), TT (16.5%) and CT (38.5%). The allele frequencies were C (64.0%) and T (36.0%). The single nucleotide polymorphism was in Hardy-Weinberg equilibrium in the studied sample. No association of the single nucleotide polymorphism rs693 with lipid profile nor the body mass index was found (p >0.05). Conclusion: There is no significant association between single nucleotide polymorphism rs693 and body mass index nor lipid profile, in a sample of Colombian Caribbeans.

Abstract Objective To assess the prevalence of illegal drug use in college students on any previous occasion, during the previous year and the previous month, and to analyze the relationship between illegal drug use and family support and other factors. Methods A cross-sectional study using data from students participating in the uniHcos project (n = 3767) was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives, stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent variables were: family support, age, residence, and employment status. To determine the factors related to drug use multivariate logistic regression models stratified by gender were fitted. Results Differences between men and women in prevalence of illegal drug use except non-prescription sedatives were observed. In both genders, less family support was associated with higher consumption of all drugs, except depressants, and with polyconsumption. To be studying and looking for work was related to cannabis and stimulant use and to polyconsumption among women, but only to cannabis use among men. Conclusions These results support the notion that the start of university studies is a particularly relevant stage in the onset of illegal drug use and its prevention, and that consumption may be especially associated with family support.

Resumen Objetivo Evaluar la prevalencia del consumo de drogas ilegales en estudiantes universitarios y analizar la relación entre dicho consumo, el apoyo familiar y otros factores. Método Se realizó un diseño transversal basado en datos de participantes en el proyecto uniHcos (n = 3767). Se evaluaron la prevalencia y la edad de inicio del consumo de cannabis, tranquilizantes sin receta, estimulantes y depresores, y el policonsumo. Como variables independientes se consideraron el apoyo familiar, la edad, la residencia y la situación laboral. Para la determinación de los factores asociados al consumo de drogas se ajustaron modelos de regresión logística estratificados por sexo. Resultados Se observaron diferencias entre hombres y mujeres en la prevalencia del consumo de todas las drogas ilegales, excepto tranquilizantes sin receta. En ambos sexos, cuanto peor apoyo familiar, mayor consumo de todas las drogas, excepto depresores y policonsumo. Encontrarse estudiando y buscando trabajo se relacionó con el consumo de cannabis, estimulantes y policonsumo en las mujeres, y solo con cannabis en los hombres. Conclusiones Los resultados de este estudio aportan nueva evidencia a favor de que el inicio de la etapa universitaria es un momento de especial relevancia en el inicio del consumo de drogas ilegales y su prevención, pudiendo este consumo estar especialmente relacionado con el apoyo familiar.

ABSTRACT Background: The voice in the academic context is a determining factor in the life of the teaching staff. The objective of this study was to evaluate the index vocal inability of in-service teachers and check your involvement the occupational conditions. Methods: For it, a descriptive-inferential study is done of cross-section to 480 teachers (average age: 45.14 ± 9.22), applying the questionnaire of vocal disability index (HIV-30). Using descriptive statistical techniques (mean and standard deviation) and inferential techniques (ANOVA). Statistical analysis was performed using SPSS v.23.0. Results: When applying the Voice Handicap Index (VHI-30) evidenced that teachers present a moderate vocal disability (41.2 rating), with increased risk in physical ability and own vocal function. Moreover, it was found that gender, educational stage, teaching load, antique, daily and weekly hours, student ratio and level of noise in the classroom, significantly affect the disturbance of the voice. It also shows more presence of dysphonia in teachers who perceive a progressive worsening of her voice throughout the day or week, and is absent in the work due to disorders of the voice. Conclusions: In conclusion, teachers attributed their laryngeal discomfort mainly to factors of the teaching context.

RESUMEN Fundamentos: La voz en el contexto académico es un factor determinante para el profesorado. El objetivo de este estudio fue evaluar el índice de incapacidad vocal de los docentes en ejercicio y comprobar su afectación según sus condiciones personales y ocupacionales. Métodos: Para ello se realiza un estudió descriptivo-inferencial de corte transversal a 480 docentes (media de edad: 45,14 ± 9.22), aplicando el cuestionario de índice de incapacidad vocal (VHI-30). Se emplearon técnicas estadísticas descriptivas (media y desviación típica) e inferenciales (ANOVA). El análisis estadístico se realizó con el software SPSS v.23.0. Resultados: Al aplicar el Voice Handicap Index (VHI-30) se evidencio que los docentes presentan una incapacidad vocal moderada (puntuación 41,2), con mayor riesgo en su capacidad física y la propia función vocal. Además, se encontró que el sexo, la etapa educativa, la carga docente, la antigüedad, las horas lectivas semanales y diarias, el ratio del alumnado y el nivel de ruido en el aula, repercuten significativamente en la perturbación de la voz. También se manifestó una mayor presencia de disfonía en los docentes que percibían un empeoramiento progresivo de su voz a lo largo del día o semana y se habían ausentado en el trabajo debido a afecciones de la voz. Conclusiones: El profesorado atribuye sus molestias laríngeas fundamentalmente a factores del contexto docente.

Abstract: This work describes the echolocation pulses produced by Myotis velifer during postnatal development. The aim was to record the changes of these calls during the development of this bat species and investigate the underlying causes. Bat specimens were sampled in El Salitre cave, Morelos, Mexico, during May and June 2016, where juvenile bats were captured and sorted into five age classes. Forearm length was used as reference for offspring growth. Each juvenile bat was induced to fly and the echolocation calls produced were recorded using an ultrasound detector. Six quantitative characteristics of the echolocation pulses of each call were measured, which served as reference to explore the development of this system during growth through a linear regression. A steady increase in the frequency parameters associated with bat growth was observed, coupled with a decrease in the temporal parameters. The final pulse frequency was the only parameter that remained unchanged during postnatal growth. The major changes in the characteristics of echolocation pulses during postnatal growth in M. velifer follow the pattern observed in other species previously studied. These changes are likely related to the development of organs and muscles involved in the emission and reception of sound, and to the learning process involved in the use of this adaptation.

Resumen: En este trabajo realizamos grabaciones de los sonidos de ecolocalización de Myotis velifer con el propósito de describir los cambios que ocurren en las caractetrísticas de los pulsos durante su crecimiento postnatal. Realizamos muestreos en la cueva El Salitre, Morelos, México durante mayo y junio del 2016, donde se capturaron las crías y se clasificaron en cinco clases de edad. La longitud del antebrazo se utilizó como indicador del crecimiento de las crías. Fuera de la cueva, los individuos fueron liberados o forzados a intentar el vuelo para obtener las grabaciones de sus ultrasonidos utilizando un detector ultrasónico. Se midieron seis características cuantitativas de los pulsos de ecolocalización de cada individuo, las cuales sirvieron como referencia para estudiar el desarrollo de este sistema durante el crecimiento por medio de una regresión lineal. Los resultados mostraron un aumento progresivo en los parámetros de frecuencia asociado al crecimiento de las crías, así como una disminución en los parámetros temporales. La frecuencia final fue el único parámetro que no mostró modificaciones significativas durante el crecimiento postnatal. Los cambios notables en las características de los pulsos de ecolocalización durante el crecimiento posnatal de M. velifer siguen el patrón observado de especies anteriormente estudiadas. Es posible que estos cambios estén relacionados con el desarrollo de los órganos y músculos involucrados en la emisión y recepción del sonido y el aprendizaje del uso de esta adaptación.

Abstract The renal glomerulus highly vascularized structure is affected by a small vessel vasculitis group associated with neutrophil cytoplasmic antibodies (ANCA) described by its relative scarcity of pauci-immune deposits as immune. This vasculitis is classified according to international consensus in Chapel-Hill microscopic poliangetitis, granulomatosis with polyangiitis, eosinophilic granulomatosis and the called vasculitis limited to the kidney. From the anatomopathological point of view, the rapidly progressive glomerulonephritis can be divided into pauci-immune, anti glomerular basement membrane and mediated by immune complexes. The treatment is generally based on immunosuppressive therapy and renal therapy support from conservative measures to renal replacement therapy. This paper reports a case of rapidly progressive glomerulonephritis associated with ANCA pathological confirmation.

Resumen El glomérulo renal, estructura altamente vascularizada, se ve afectado por un grupo de vasculitis de pequeño vaso asociadas con anticuerpos anticitoplasma de neutrófilo (ANCA), descritas por su relativa escasez de depósitos inmunes como pauciinmunes. Estas vasculitis se clasifican según el consenso internacional de Chapel-Hill en poliangeítis microscópica, granulomatosis con poliangeítis, granulomatosis eosinofílica y la llamada vasculitis limitada al riñón. Desde el punto de vista anatomopatológico, la glomerulonefritis rápidamente progresiva puede dividirse en pauciinmune, antimembrana basal glomerular (GBM GN) y mediada por inmunocomplejos. El tratamiento, en general, es con inmunosupresor y terapia renal de soporte desde medidas conservadoras hasta tratamiento de sustitución renal. Se comunica un caso de glomerulonefritis rápidamente progresiva asociada con ANCA por confirmación anatomopatológica.
