ABSTRACT The relevance of managerial action within the school system became evident in the crisis caused by COVID-19. The purpose of this research is to show the experiences experienced by managers to meet the needs caused by the crisis. To achieve this, the qualitative and comparative approach was used, integrating the principles of symbolic interactionism, using focus groups as a technique for collecting information and, for its analysis, the inference ladder method. It is concluded that the impact on schools was different and diverse in each due to different conditions. Thus, the strategies undertaken by managers responded to their own reality. Conventional institutions found it more difficult to deal with the crisis, while versatile organizations were able to adapt to the new remote learning ecosystem more effectively.

RESUMEN La relevancia que la acción directiva tiene dentro del sistema escolar se hizo patente en la crisis causada por el COVID-19. Esta investigación tiene como propósito mostrar las vivencias de directivos para atender a las necesidades a causa de la crisis. Para lograrlo se utilizó el enfoque cualitativo y comparativo, integrando los principios del interaccionismo simbólico. Para la recolección de la información se utilizaron grupos focales y, para su análisis, el método de la escalera de la inferencia. Se concluye que el impacto en las escuelas fue diferente, debido a las condiciones de cada una. Así, las estrategias emprendidas por los directivos atendieron a la propia realidad. En las instituciones convencionales se presentaron mayores dificultades para enfrentar la crisis, mientras que las organizaciones versátiles pudieron adaptarse al nuevo ecosistema de aprendizaje remoto con mayor eficacia.

Abstract Porcine epidemic diarrhea (PED) is a highly contagious enteric disease of pigs, which has caused great economic losses to the swine industry worldwide. The known measure for PED control prior to the development and launch of vaccines in 2017 in Mexico, was "feedback" or "liquefaction". It was a widely used measure during the PED outbreak in 2013; however, there is no homogeneity in its use among the various authors who recommend it. Currently, several studies have experimented with other types of prophylaxis, such as oral immunization with PED virus obtained from cell culture isolation, which allows quantification of the infectious virus and ensures that only the virus, and no other agent, is being used as inoculum. The objective of the present study was to compare the time of seroconversion in sows inoculated with the quantified virus with four different vehicles (milk, wheat, direct, and water) and different doses of vehicle (1 ml, 2 ml, and 3 ml) at different pregnancy stages and with a different number of farrowings. The study was conducted at CEIEPP, a full-cycle farm with 170 females. The present study showed that the vehicles with the best results were the inoculum with water and the direct inoculum combined with the 1 ml dose, as the combination of these vehicles and an inoculum dose resulted in seroconversion in more than 90 % of the sows from the second week post inoculation.

Resumen La diarrea epidémica porcina (PED) es una enfermedad entérica altamente contagiosa en los cerdos, que ha provocado grandes pérdidas económicas a la industria porcina a nivel mundial. Las medidas conocidas para el control de la PED, antes del desarrollo y lanzamiento de las vacunas en el 2017 en México, fue el “feedback” o “licuado”. Aunque fue una medida muy utilizada durante el brote de PED en 2013, entre los diversos autores que lo recomiendan no hay una homogeneidad en su uso. Actualmente, diversos estudios han experimentado otro tipo de profilaxis, como la inmunización oral con el virus de la PED obtenido a partir del aislamiento en cultivo celular, lo que permite cuantificar el virus infectivo, así como asegurar que solo se está utilizando como inóculo al virus y no otros agentes. El objetivo del presente estudio fue comparar el tiempo de seroconversión, en cerdas inoculadas con virus cuantificado, con cuatro diferentes vehículos (leche, trigo, directo y agua) y diferentes dosis del vehículo (1 ml, 2 ml y 3 ml), en diferentes momentos de gestación y número de partos. El estudio se realizó en el CEIEPP, granja de ciclo completo con 170 hembras. El presente estudio demostró que los vehículos con mejores resultados fueron el inóculo con agua y el inóculo directo combinado con la dosis de 1 ml, ya que la combinación de estos vehículos y dosis del inóculo generó que más del 90 % de las cerdas mostraran seroconversión a partir de la segunda semana post-inoculación.

Abstract Background: Small cell lung cancer (SCLC) represents 13-15% of all primary lung neoplasms and is characterized by rapid growth rate and development of distant metastases. Objectives: To guide and standardize the treatment of limited disease small cell lung cancer in Mexico based on national and international clinical evidence. Material and methods: This document was developed as a collaboration between the National Cancer Institute and the Mexican Society of Oncology in compliance with international standards. An interdisciplinary group was formed, including medical oncologists, oncological surgeons, thoracic surgeons, radiation oncologists, and methodologists with experience in systematic reviews of the literature and clinical practice guidelines. Results: Consensus recommendations were reached, both by the Delphi method and in remote meetings, for limited SCLC disease resulting from the same number of work questions. The scientific evidence that answers each of these clinical questions was identified and critically evaluated, before being incorporated into the body of evidence of the guide. Conclusion: This guide provides clinical recommendations for the management of limited disease SCLC to contribute to the decision-making process of the clinicians involved with its management in our country, hoping that this will contribute to improving the quality of clinical care in these patients.

Resumo O trabalho apresenta os resultados de uma pesquisa qualitativa realizada com estudantes de medicina de uma Liga de Saúde Mental e Psiquiatria (LASMP). Teve como objetivos sensibilizá-los para perceber a si mesmos como pessoas e instrumentalizá-los com outras racionalidades distintas das formas de pensamento biomédicas. Os grupos reflexivos, por meio do círculo de cultura, ofereceram espaço de livre circulação da palavra, tempo para reflexões e compartilhamento de experiências cotidianas vividas em plena formação. Configuraram-se como estratégia de mudança e um despertar para repensar modelos de saúde mais voltados para o cuidado do que para doenças. A observação participante permitiu descortinar, por meio das narrativas, particularidades das experiências, dos discursos e da cultura do próprio grupo. As análises foram realizadas pelo método da reflexividade (Bourdieu, 2001; 2004), por permitir o aprofundamento sistemático dos conteúdos das narrativas. Sem pretensão de síntese, o percurso reflexivo sobre as narrativas partiu dos pressupostos do pensamento e das ações para chegar aos sentidos construídos e partilhados. Ofereceram possibilidades de transformação do modo de ver o mundo do trabalho, a si mesmos e as pessoas a sua volta; de mudança na compreensão da saúde mental para além do plano individual.

Abstract This paper set out to present the outcomes of qualitative research conducted with medical students of a Mental Health and Psychiatry League (LASMP). Its objectives were to sensitize them to perceive themselves as people and provide them with other rationales different from biomedical ways of thinking. The reflexive groups, within the culture circle, provided an opportunity for an exchange of ideas, time for reflection and sharing of fully formed daily experiences. They were configured as a strategy of change and awakening to rethink models of health more focused on healthcare than on diseases. Participant observation enabled revealing, through the narratives, particularities of the experiences, discourses and culture of the group itself. The analyses were carried out using the reflexivity method (Bourdieu, 2001; 2004), as it permits the systematic deepening of the contents of the narratives. Without any pretension of synthesis, the reflexive course on the narratives started from the assumptions of thought and actions to arrive at the constructed and shared meanings. They offered possibilities of transforming the way of perceiving the world of work, themselves, and the people around them; of changing the understanding of mental health beyond the individual level.

Desde o lançamento da terceira versão do Manual Diagnóstico e Estatístico de Transtornos Mentais (DSM-III), a psiquiatria biológica vem sistematicamente aplicando seu raciocínio classificatório a fenômenos sociais de múltiplas naturezas. Nessa perspectiva, ganha relevância o discurso do trauma, pelo qual acontecimentos de magnitude devastadora passaram a receber interpretações neurocomportamentais e foram, finalmente, reconhecidos menos por seus impactos culturais e subjetivos que pelas alterações fisiológicas que propiciam. Apoiado em revisão narrativa, este artigo procurará explorar a transição da racionalidade traumática entre o século XIX, quando o trauma fora concebido em associação ao conceito cognitivo de memória, e o século XX, quando finalmente esse fenômeno foi anexado à pesquisa neurocientífica do estresse. A pluralidade de modelos conceituais e paradigmas determinísticos pode contribuir para que a pesquisa do trauma produza protocolos de enfrentamento multifatoriais mais adequados à experiência humana do sofrimento pós-traumático.

Since the release of the third version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), biological psychiatry has been systematically applying its classification reasoning to social phenomena of many natures. From this perspective, the discourse of trauma gained relevance and events of devastating magnitude began to receive neurobehavioral interpretations until finally being recognized less for their cultural and subjective effects than for the physiological changes they cause. By a narrative review, this study aims to analyze the transition of traumatic rationality from the 19th century, when trauma was associated with the cognitive concept of memory, to the 20th century, when this phenomenon was finally attached to neuroscientific research on stress. The plurality of conceptual models and deterministic paradigms can contribute to the fact that trauma research produces multifactorial coping protocols more appropriate to the human experience of post-traumatic suffering.

Desde la publicación de la tercera versión del Manual Diagnóstico y Estadístico de los Trastornos Mentales (DSM-III), la psiquiatría biológica ha aplicado sistemáticamente su razonamiento clasificatorio a fenómenos sociales de múltiple naturaleza. Desde esta perspectiva cobra relevancia el discurso del trauma, a través del cual eventos muy devastadores pasaron a tener interpretaciones neuroconductuales y finalmente fueron reconocidos menos por sus impactos culturales y subjetivos que por los cambios fisiológicos que provocan. A partir de una revisión narrativa, este artículo busca explorar la transición del razonamiento traumático entre el siglo XIX, cuando el trauma se concibe en asociación con el concepto cognitivo de memoria, y el siglo XX, cuando este fenómeno se vincula a la investigación neurocientífica sobre estrés. La diversidad de modelos conceptuales y paradigmas deterministas puede contribuir a que la investigación del trauma produzca protocolos de afrontamiento multifactoriales más adecuados a la experiencia humana del sufrimiento postraumático.

ABSTRACT Azotobacter vinelandii is a Gram negative that undergo a morphological and physiological differentiation process to form cysts resistant to desiccation. The main components of a cyst are alkylresorcinols (ARs), phenolic lipids of 21 to 23 C. These lipids are homologous to plant ARs, where they have been reported to have antifungal properties. The objective of this study was to evaluate the antifungal capacities of vegetative cells and cysts of A. vinelandii AEIV. The cysts were visualized by optical microscope and the detection of ARs was performed by thin layer chromatography. Antagonism bioassay were carried out between vegetative cells and cysts against Fusarium brachygibbosum, Aspergillus niger and Colletotrichum gloeosporioides. We confirmed the induction of cysts and the presence of ARs of A. vinelandii AEIV. We observed that using 1×103 cysts reduced up to 76.3% (p < 0.05) the growth of the three phytopathogenic fungi and this result was not observed when using vegetative cells or the strain blocked in the synthesis of ARs. This shows that the cysts exert an antagonistic effect on phytopathogenic fungi and do so through the ARs, considering the development of an effective strategy to control pests in fungi that affect postharvest fruits.

Abstract Serologic tests are important for the detection of specific antibodies against infectious agents. Commercial indirect ELISA are costly and usually as effective as in-house ELISAs. In the present work, it was prepared a batch of Anaplasma marginale crude antigen from infected blood, and tested it against official positive and negative serum controls and compared with an old batch of antigen. The new antigen batch showed an efficiency similar to the old batch. The sensitivity of the test was comparable between the new and old batches. Both, new and old antigen lots are being used at an excess. The new antigen lot is large enough to run thousands of tests at a more affordable price than commercial kits.

Resumen Las pruebas serológicas son importantes para la detección de anticuerpos específicos contra agentes infecciosos. Los ELISA indirectos comerciales son costosos y, por lo general, son tan efectivos como los ELISA caseros. En el presente trabajo fue preparado un lote de antígeno crudo de Anaplasma marginale a partir de sangre infectada, y se probó contra controles oficiales de suero positivos y negativos y comparado con un lote viejo de antígeno. El nuevo lote de antígenos mostró una eficiencia similar a la del lote viejo. La sensibilidad de la prueba entre los lotes nuevo y viejo fue comparable. Tanto el lote de antígeno nuevo como el viejo se están utilizando en exceso. El nuevo lote de antígeno es lo suficientemente grande como para ejecutar miles de pruebas a un precio más asequible que el de los kits comerciales.

Abstract Highly diluted bioactive compounds have been successfully used in the agricultural sector to stimulate plant growth and development even in unfavorable crop conditions. For this reason, the feasibility of using Natrum muriaticum (NaM), a homeopathic ultradilution, as an elicitor agent against the negative effects of salt stress by NaCl, was studied in two varieties of basil (Ocimum basilicum L) grown in a saline medium, at CIBNOR, SC.), in February-March 2019. A completely randomized design with a factorial arrangement (2A×2B×3C) was applied, considering the Napoletano and Emily varieties as factor, the concentration of NaCl (0 and 75 mM) as factor B, and the homeopathic treatments NaM (7CH, 13CH and distilled water as control) as factor C, adding a total of 12 treatments with four repetitions each, and photosynthetic-rate and production of fresh and dry biomass of aerial part as response variables. The analysis of variance and multiple comparisons of means (Tukey HSD p≤ 0.05) revealed that both dynamizations of NaM (7CH and 13CH) favored an increase in the response variables evaluated in plants subjected to salt stress. The highest increase in photosynthetic rate (75%) and fresh biomass of the aerial part (40%) with respect to the control treatment was obtained with NaM 7CH in the Napoletano variety. In conclusion, the application of NaM attenuates salt stress in Ocimum basilicum L, confirming that agricultural homeopathy is an eco-friendly alternative that can increase basil production under salt stress conditions.

Resumen Los compuestos bioactivos altamente diluidos se han utilizado con éxito en el sector agrícola para estimular el crecimiento y desarrollo de las plantas, incluso en condiciones de cultivo desfavorables. Por esta razón, se estudió la viabilidad de utilizar Natrum muriaticum (NaM), una ultradilución homeopática, como agente elicitor contra los efectos negativos del estrés salino por NaCl, en dos variedades de albahaca (Ocimum basilicum L.) cultivadas en un medio salino, en el CIBNOR, SC., en febrero-marzo de 2019. Se aplicó un diseño completamente al azar con un arreglo factorial (2A×2B×3C), considerando las variedades Napoletano y Emily como factor A, la concentración de NaCl (0 y 75 mM) como factor B, y los tratamientos homeopáticos con NaM (7CH, 13CH y agua destilada como control) como factor C, sumando un total de 12 tratamientos con cuatro repeticiones cada uno, y la tasa fotosintética y producción de biomasa fresca y seca de la parte aérea como variables de respuesta. El análisis de varianza y las comparaciones múltiples de medias (DSH de Tukey p≤ 0.05) revelaron que ambas dinamizaciones de NaM (7CH y 13CH) favorecieron un aumento de las variables de respuesta evaluadas en plantas sometidas a estrés salino. El mayor aumento de la tasa fotosintética (75%) y de la biomasa fresca de la parte aérea (40%) con respecto al tratamiento control se obtuvo con NaM 7CH en la variedad Napoletano. En conclusión, la aplicación de NaM atenúa el estrés salino en Ocimum basilicum L., lo que confirma que la homeopatía agrícola es una alternativa respetuosa con el medio ambiente que puede aumentar la producción de albahaca en condiciones de estrés salino.

Abstract Massive hemoptysis is a rare life-threatening complication of pulmonary actinomycosis that should be treated promptly due to the risk of asphyxiation and hemodynamic instability. We present the case of a 57-year-old female who was presented to our center with massive hemoptysis. Thoracic computed tomography scan revealed a cavitated lesion with perilesional ground-glass opacity. Right lower lobectomy was then performed using uniportal video-assisted thoracic surgery, excising a 13 × 12 × 8 cm cavitated lung fragment. The pathology service reported the presence of microscopical evidence of filamentous gram positive bacterial colonies, showing compatible features of pulmonary actinomycosis. The patient was discharged with oral penicillin with an uneventful post-operative course.

Resumen La hemoptisis masiva es una complicación poco frecuente de la actinomicosis pulmonar que pone en peligro la vida del paciente y que debe ser tratada con prontitud debido al riesgo de asfixia e inestabilidad hemodinámica. Presentamos una mujer de 57 años que acudió a nuestro centro con hemoptisis masiva. La tomografía reveló una cavitación con opacidad perilesional en vidrio deslustrado. Realizamos lobectomía mediante cirugía uniportal, extirpando un fragmento de lesión. Patología informó de la presencia de colonias bacterianas filamentosas grampositivas, mostrando características compatibles con actinomicosis pulmonar. El paciente fue dado de alta con penicilina oral, con un curso postoperatorio sin incidentes.

RESUMO No México, o milho crioulo apresenta problemas de podridão das sementes. Portanto, o objetivo desta pesquisa foi determinar a frequência de fungos associados a sementes de milho crioulo. De janeiro e fevereiro de 2019, 13 amostras de milho crioulo foram coletadas em localidades de Guerrero, México. As amostras foram processadas em meio de cultura BDA e a frequência de cada fungo foi estimada com base nas características culturais e chaves taxonômicas. Nas amostras sintomáticas de sementes de milho, Fusarium oxysporum foi registrado em oito amostras com 97,2%, seguido por F. graminearum isolado na raça de milho “Olotillo 1” com 94,4% e na raça “Cónico pepitilla” com 58,3%. Phomopsis sp., foi isolado 100% na raça “Olotillo 2”. Gibberella moniliformis, foran isolados de “Elotes Occidental 1” com 83,3% e o menos frequente (19,4%) em “Pepitilla” foi Sarocladium strictum registrado em três amostras com valores baixos de 11,1% e 2,8% na raça de milho “Arrocillo 2” e “Pepitilla”, Talaromyces variabilis em duas amostras com 11,1% e 2,8% em “Arrocillo 2” e “Cónico pepitilla”. Stenocarpella macrospora foi isolado em 72,2% da raça de milho “Pepitilla”. Aspergillus flavus em “Cónico Pepitilla” com 16,7%, Setosphaeria turcica e Emericella sp., foi isolado com menor frequência. Em sementes assintomáticas da raça “Cónico pepitilla” foi isolado F. oxysporum com 8,3%, Fusarium acuminatum 8,3%, Gibberella moniliformis em 41,7%, em sementes assintomáticas de “Olotillo 1” e “Olotillo 2” Phomopsis sp., foi isolado em 50% e Rhizoctonia solani com 50%. Neste estudo, os fungos F. oxysporum, Phomopsis sp., G. moniliformis e F. graminearum foram os mais frequentemente associados às sementes de milho crioulo.

ABSTRACT In Mexico, Creole corn has presented problems related to seed rot. Therefore, the objective of this study was to determine the frequency of fungi associated with Creole corn seeds. From January to February 2019, 13 Creole corn samples were collected from several localities in Guerrero, Mexico. The samples were processed in PDA culture medium and the frequency of each fungus was estimated based on cultural characteristics and taxonomic keys. Considering symptomatic corn seed samples, Fusarium oxysporum was recorded in eight samples at 97.2%, followed by F. graminearum, isolated from race “Olotillo 1” at 94.4% and from race “Cónico pepitilla” at 58.3%. Phomopsis sp. was isolated at 100% from race “Olotillo 2”. Gibberella moniliformis was isolated from “Elotes Occidental 1” at 83.3%, while the least frequent isolate (19.4%) from “Pepitilla” was Sarocladium strictum, which was recorded in three samples at the low values of 11.1% and 2.8% for races “Arrocillo 2” and “Pepitilla”, respectively; Talaromyces variabilis was found in two samples at 11.1% and 2.8% from “Arrocillo 2” and “Cónico pepitilla”, respectively; Stenocarpella macrospora was isolated at 72.2% from “Pepitilla”. Aspergillus flavus was obtained from “Cónico Pepitilla” at 16.7%, while Setosphaeria turcica and Emericella sp. were less frequently isolated. Considering asymptomatic seeds of race “Cónico pepitilla”, F. oxysporum was isolated at 8.3%, Fusarium acuminatum at 8.3% and Gibberella moniliformis at 41.7%; from asymptomatic seeds of “Olotillo 1” and “Olotillo 2”, Phomopsis sp. was isolated at 50% and Rhizoctonia solani at 50%, respectively. In the present study, the fungi F. oxysporum, Phomopsis sp., G. moniliformis and F. graminearum were most frequently associated with Creole corn seeds.

ABSTRACT Objective: To evaluate the response to cabergoline (CBG) treatment in patients with non-functioning pituitary adenomas (NFPA). Subjects and methods: Retrospective, single tertiary care center study. A total of 44 patients were treated with 3 mg/week of CBG, 32 after surgical treatment (transsphenoidal surgery [TSS] in 27 and TC in 5 patients) and 12 as primary therapy. Mean age was 59.2 ± 12 years and 23 (52.2%) were women. Response to therapy was ascertained by serial magnetic resonance imaging. The median duration of CBG therapy was 30 months (IQR 24-48). Response to CBG therapy was defined as a greater than 20% reduction in tumor size and volume. Results: A significant reduction in tumor size was documented in 29 patients (66%), whereas in 11 patients (25%) the tumor increased in size and in 4 (9%), it remained stable. Significant tumor shrinkage was documented in 4 (33.3%) of 12 patients treated primarily and in 23 (71.8%) of those treated secondarily. The three-year progression-free survival was 0.61. Conclusion: Cabergoline therapy is effective in reducing tumor growth in over two thirds of patients with NFPA, however 16% of patients will escape to this beneficial effect and will require alternative forms of treatment to halt tumor progression.

Abstract The objective of this research work was to analyze the health and poverty indicators that influence the increase in infections by the type 2 coronavirus that causes severe acute respiratory syndrome (SARS-CoV-2) through two predictive models. An analysis was carried out in 2409 municipalities of Mexico in two periods of time. For period two (July 13, 2021) the variables "Pneumonia", "Asthma", "Other complication", "Obesity" and "Other case" influenced the spread of covid-19 in 0.4024, 0.5229, 2.4246, 1.0053 and 1.4788, respectively. Similarly, the lack of income, housing and food were social variables that influenced the number of infections, due to the fact that a "healthy distance" could not be maintained. It concludes with the demand that the Government apply greater measures of both health and social awareness to the contagion of covid-19, as well as social programs in places where there are vulnerable people due to income, people with a lack of quality and housing spaces. and people with lack of access to food.

Resumen El objetivo de este trabajo de investigación fue analizar los indicadores de salud y de pobreza que influyen en el aumento de contagios por el coronavirus de tipo 2 causante del síndrome respiratorio agudo severo (SARS-CoV-2) a través de dos modelos predictivos. Se realizó un análisis en 2409 municipios de México en dos periodos de tiempo. Para el periodo dos (13 de julio del 2021) las variables “Neumonía”, “Asma”, “Otra complicación”, “Obesidad” y “Otro caso” influyeron en el contagio de covid-19 en 0.4024, 0.5229, 2.4246, 1.0053 y 1.4788, respectivamente. De igual forma, las carencias de ingresos, vivienda y alimentación fueron variables sociales que influyeron en el número de contagios, debido a que no se pudo mantener “sana distancia”. Se concluye con la demande de que el Gobierno aplique mayores medidas tanto de salud como de conciencia social al contagio del covid-19, así como de programas sociales en los lugares donde existan personas vulnerables por ingresos, personas con carencia en calidad y espacios de vivienda y personas con carencia en acceso a la alimentación.

Resumo O objetivo deste trabalho de pesquisa foi analisar os indicadores de saúde e pobreza que influenciam o aumento de infecções pelo coronavírus tipo 2 causador da síndrome respiratória aguda grave (SARS-CoV-2) por meio de dois modelos preditivos. Uma análise foi realizada em 2.409 municípios do México em dois períodos de tempo. Para o período dois (13 de julho de 2021) as variáveis “Pneumonia”, “Asma”, “Outra complicação”, “Obesidade” e “Outro caso” influenciaram a disseminação da covid-19 em 0,4024, 0,5229, 2,4246, 1,0053 e 1,4788, respectivamente. Da mesma forma, a falta de renda, moradia e alimentação foram variáveis sociais que influenciaram o número de infecções, devido ao fato de que uma "distância saudável" não poderia ser mantida. Conclui com a exigência de que o Governo aplique maiores medidas tanto de saúde como de sensibilização social para o contágio da covid-19, bem como programas sociais em locais onde existam pessoas vulneráveis devido a rendimentos, pessoas com falta de qualidade e espaços habitacionais .e pessoas com falta de acesso a alimentos.
