Notes on the correct identity of Ceratostylis siamensis (Epidendroideae: Podochileae) from India
Authors: Sarkar Shuvadip , AGRAWALA DINESH KUMAR , Maity Debabrata , Khanal Madhusudhan
Published: February 2025

While conducting taxonomic studies on the tribe Podochileae (Orchidaceae) for the Flora of India, two species, Ceratostylis siamensis and Ceratostylis himalaica have been examined using types, protologues, fresh specimens, and authentic herbarium collections. Ceratostylis siamensis was previously reported and documented in Arunachal Pradesh, India. However, we determined upon closer examination that this record was based on erroneous identification. The correct identity of this species is C. himalaica. Consequently, Ceratostylis siamensis is excluded from the flora of India.
Maçonaria e Memória: Um vínculo esquecido, elos perdidos
Authors: Pinheiro Ivan
Published: February 2025

Na Maçonaria a ars memoriae já há tempos encontra-se oculta em meio às ritualísticas, ora nas entrelinhas das Artes Liberais, ora por entre as Virtudes Cardeais. Todavia, a sua importância pode ser ainda maior se explicar a transição da Fase Operativa à Especulativa, hipótese aventada por Frances A. Yates. Ao seguir essa trilha, este estudo analítico-crítico, lastreado na literatura traz uma hipótese inusitada: as Fases Operativa e Especulativa podem ter sido concomitantes ou, com maior ousadia especulativa, tendo por base a historiografia oficial, a última, lato sensu, pode mesmo ter antecedido a primeira.

Soil Salinity Prediction Using Satellite-Based Variables and Machine Learning: Case study in Tra Vinh province, Mekong Delta, Vietnam
Authors: Nguyen Huu Duy , Pham Viet Thanh , Nguyen Quoc-Huy , Bui Quang-Thanh
Published: February 2025

The precision of estimating soil salinity is considered a key task in solving soil salinity problems and irrigation management of agriculture. This problem is increasingly important in the Mekong Delta, where it is severely affected by this phenomenon in the context of climate variability. Therefore, this paper aims to construct a soil salinity map with high accuracy using machine learning and Sentinel 2A, namely Xgboost (XGB) and Random Forest (RF). The province of Tra Vinh in the Mekong Delta has been selected as the case study. 68 soil salinity samples were collected in August 2024, and 25 conditioning factors extracted from the Sentinel 2A image were used as input data for the machine-learning model. Three statistical indices, namely root mean square error (RMSE), mean absolute error (MAE), and coefficient of determination (R2), were used to evaluate the effectiveness of machine learning models. The results showed that with an R2 value of 0.86, the XGB model was superior to the RF model with an R2 value of 0.67. Furthermore, Tra Vinh province, the coastal region, and along the Mekong River are more severely affected by soil salinity with an electrical conductivity (EC) value of more than 10. This region, more affected by soil salinity, is related to rising tides and sea levels in the context of climate variability. This study plays an important role and can support farmers in regions affected by soil salinity in building investment measures to reduce the impacts of soil salinity on the development of agriculture.

The Sixty Years’ War: The Platine World-Region and the Causes of the 1864 Conflict
Authors: GOYENA SOARES RODRIGO
Published: February 2025

ABSTRACT This article proposes a theoretical-methodological framework using the concept of the world-region to reassess the causes of the 1864 conflict. It argues that the prevailing systemic alliances perspective in historiography might insufficiently account for the temporal dimension characteristic of the world-region. According to this proposal, the 1864 conflict arose from a contentious geopolitical environment and significantly from the inclusion of historical perspectives in redefining national interests. Beyond spatial unity or integration into the world economy dominated by Great Britain, the River Plate basin in the 19th century was defined as a world-region by two main temporal layers. The first, lasting until the mid-century, was marked by the contentious formation of nation-states, which Brazil resolved in regional hegemony. The subsequent contradictions, representing a second temporal layer extending until 1870, highlighted threats to this new status quo, specifically Brazilian unipolarity. Therefore, the 1864 conflict, essentially an episode of the Sixty Years’ War, had deeper roots in the 1851-1852 reconfiguration of the Platine basin rather than the 1863-1864 alliances, which were merely outcomes of this second temporal layer, characterized by already established nation-states.

Malaria is a parasitic disease of great relevance in global public health. The development of new sensitive and specific diagnostic high-throughput methods remains a challenge in the eradication of this disease. In this study, we developed a flow cytometry test using latex microbeads and polyclonal antibodies obtained from rabbits and mice for the detection of the P. vivax lactate dehydrogenase (PvLDH) antigen. We processed 50 samples from Brazilian patients diagnosed with malaria caused by P. vivax and 40 samples from healthy individuals. The assay presented sensitivity of 64%, specificity of 97%, a positive predictive value of 97%, and a negative predictive value of 57% when analyzed using the fluorescent labeling method. Using the mean fluorescence intensity (MFI) analysis method, the sensitivity was 53%, specificity was 89%, the positive predictive value was 95%, and the negative predictive value was 33%. In both methods of analysis, we observed significant statistical differences between the analyzed groups (P-value <0.0001). A high correlation (0.60) between the two methods and a low correlation between PvLDH concentration and parasite density was found. The test was able to detect the PvLDH protein with high specificity, but its sensitivity should be improved. More promising results were observed when the samples were analyzed according to the percentage of fluorescent labeling. Improvement of this assay would enable its application as a serological test for the detection of asymptomatic patients and for the validation of rapid diagnostic tests.

Esta pesquisa tem como objetivo analisar a abordagem utilizada pela plataforma Geekie One para o ensino de língua espanhola, por meio das atividades, sob a perspectiva da complexidade. Para tanto, partimos da seguinte questão: De que forma ocorre a abordagem para o ensino de língua espanhola na plataforma Geekie One, por meio das atividades, sob a perspectiva da complexidade? À luz da teoria da complexidade, observamos que o ensino de uma língua, considerado aqui como um sistema adaptativo complexo, envolve uma série de fatores (agentes) que interagem de forma dinâmica e aleatória (Larsen-Freeman, 1997). Entre esses fatores, destacam-se o uso de tecnologias digitais e a abordagem por tarefas. Embora a natureza instável dos sistemas complexos torne difícil prever os resultados do ensino de línguas, a adoção da abordagem por tarefas pode aumentar as chances de sucesso, uma vez que essa abordagem é amplamente reconhecida por promover o desenvolvimento de habilidades comunicativas (Luce, 2009). Além disso, o uso de tecnologias digitais oferece diversas ferramentas que podem facilitar o processo de ensino. Nesse sentido, foi realizada uma análise das seguintes tarefas da plataforma Geekie One: “Curiosidade”, “Roda de Conversa”, “Expressando Ideias” e “Comunícate”. A análise dos dados revelou que a abordagem por tarefas, no ensino de língua espanhola mediado por tecnologias digitais, pode oferecer benefícios significativos, como incentivar os alunos a explorar a criatividade na utilização da língua-alvo.
Improving Electric Vehicle Maintenance by Advanced Prediction of Failure Modes Using Machine Learning Classifications
Authors: Moussa Attia , Aoulmi Zoubir
Published: February 2025

This study presents a novel approach for analyzing failure modes and their effects in electric vehicles, offering an alternative to traditional methods. We employed machine learning techniques, enabling a significant shift in predictive maintenance. Various models, including Random Forest, Decision Trees, Logistic Regression, and Neural Networks, were tested, with Random Forest and Neural Networks achieving an impressive accuracy of 96.67%. This advancement enhances fault prediction, reduces operational costs, and minimizes downtime by integrating numerical and categorical data. The innovation of this study lies in combining multiple models to detect more complex patterns. Unlike previous studies that relied on simpler methods like decision trees or regression analysis, our multi-layered approach improves prediction accuracy by utilizing real-world data from electric vehicle sensors. This approach overcomes the limitations of simulated data and isolated models, significantly enhancing vehicle reliability, lifespan, and maintenance.

Authors: Long Susan M. , Clark Madeline , Ausloos Clark D. , Paul Dinisha , Finch Kaylee
Published: February 2025

This qualitative content analysis provides an overview of neurodiversity constructs published in 21 peer-reviewed counseling journals between 2013 and 2022. A total of 33 articles met inclusion criteria and were analyzed. The publishing journal, year published, article type, article purpose, neurodiversity terminology, populations studied, and counseling application are identified. Findings of this content analysis revealed 14 of 21 counseling journals published articles pertinent to neurodiversity constructs within a 9-year period, with a slight increase in neurodiversity-related articles published during this time span. Implications such as increasing discussions of neurodiversity in counseling, applying a neurodiversity paradigm in clinical practice, and a call for counseling outcome research about neurodiversity are discussed.
Psychometric Evaluation of Wellness-Based Screeners: National Sample of U.S. Physicians
Authors: Kalkbrenner Michael T. , Sun Hannah , Peterson Sage
Published: February 2025

Total wellness (mental and physical health) is a core element and a foundational pillar in the mental health counseling field. The counseling literature is lacking research on supporting physicians in the United States, who are a unique population facing complex mental and physical health issues. Health-based screening has notable utility for monitoring and promoting physician wellness. However, the literature is missing a package of health-based screeners with valid scores among a normative sample of U.S. physicians. We tested the psychometric properties of the following wellness-based screeners with a national sample of U.S. physicians: Mental Health Inventory–5, Lifestyle Practices and Health Consciousness Inventory–2, and Inner Wealth Inventory. Results revealed support for convergent validity and factorial invariance of physicians’ scores on all three screeners by gender identity and help-seeking history. We offer recommendations for how these wellness-based screeners can edify the practice of mental health counselors when working with physician clients.

Published: February 2025

Este artigo analisou narrativas de jovens do Ensino Médio, a partir dos pressupostos de como as Tecnologias Digitais (TD) foram utilizadas nas aulas de Língua Portuguesa, em contexto do ensino remoto emergencial, em tempos de pandemia da Covid-19. Trata-se de um estudo que se referencia nos pressupostos da pesquisa qualitativa interpretativista, e para geração dos dados utilizamos a entrevista narrativa. O estudo realizou-se no contexto de uma escola da rede pública estadual, e teve como participantes três (03) jovens matriculados no Ensino Médio, que frequentaram as aulas na modalidade remota (2020/2021). Amparados pelas TD, a comunidade escolar e os estudantes encontraram diversos desafios, como por exemplo, a interação digital e a falta de boa qualidade de conexão com a internet, que em muitos casos acontecem com as famílias de baixa renda, ou com aquelas residentes em ambientes rurais. As aulas remotas foram um dos desafios atuais na Educação Básica, uma vez que as TD não eram usadas, cotidianamente, no contexto escolar. Importante pensar que, em meio a tudo isso, o professor teve de lidar com essas situações de modo a reinventar a sua prática docente. Além disso, a ausência de interação presencial entre docentes e estudantes foi um dos fatores apontados nas narrativas como um possível fator para a não aprendizagem.

Abstract
This article analyzes narratives from young people in high school, based on the assumptions of how Digital Technologies (DT) were used in Portuguese language classes, in the context of emergency remote teaching, in times of the Covid-19 pandemic. This is a study that refers to the assumptions of interpretive qualitative research, and to generate data we used a narrative interview. The study was carried out in the context of a state public school, and its participants were three (03) young people enrolled in high school, who attended classes remotely (2020/2021). Supported by TD, the school community and students encountered several challenges, such as digital interaction and the lack of good quality internet connection, which in many cases occur with low-income families, or with those residing in rural environments. Remote classes were one of the current challenges in Basic Education, since DTs were not used on a daily basis in the school context. It is important to think that, in the midst of all this, the teacher had to deal with these situations in order to reinvent his teaching practice. Furthermore, the lack of face-to-face interaction between teachers and students was one of the factors planned in the narratives as a possible factor for non-learning.

 Abstract
Based on the experience of more than twenty years as a teacher in a Medicine course based on an integrated curriculum and innovative methodologies that privilege student protagonism and, based on his own performance in the teaching process of Microscopic Morphological Sciences (Histology and Pathology), the researcher observed signs of demotivation and dropout among students in this scenario. He hypothesized that the predominance of theoretical classes, supported by the traditional teaching method, could be the trigger for such a possibility. This reflection gave rise to the desire to promote a renewal in their teaching practices. Thus, the objective of this work focuses on reviewing the theoretical concepts of New Learning Theories, with a focus on the teaching of Morphological Sciences, in order to support the planning of future actions aimed at the teaching process of Histology and Pathology . Conducted from qualitative research, based on a literature review, it collected scientific texts in the Google Scholar database that constituted a reflective and interpretative basis for the studies of Dewey, Bruner and Ausubel, in order to raise an applicable proposal for the process of teaching and learning of Microscopic Sciences that is meaningful, collaborative and based on the student as the protagonist.

Jump performance and field-based anaerobic capacity profiles of international standard amateur mixed martial arts athletes
Authors: Batra Amit , Finlay Mitchell , Kirk Christopher
Published: February 2025

Mixed martial arts (MMA) is a combat sport requiring the ability to complete repeated high impulse actions for 9-25 minutes. This study reports proxy measures of lower body neuromuscular performance and anerobic capacities of tier 3 standard amateur MMA athletes for the first time. A cohort of n=9 female (age = 20.5±2.8 years) and n=12 male (age=20.8±1.6 years) participants completed squat jumps, countermovement jumps, and drop jumps to provide proxy measures of their neuromuscular performance and reactive strength. The cohort also completed the special judo fitness test (SJFT) as a proxy for their anaerobic capacity. Participant’s MMA success rates were determined using their MMA bout winning %. Relationships between physiological measures and success rates were calculated using Pearson’s r correlation coefficient (p<0.05). Both male and female jump characteristics were generally equal to athletes from other combat sports, but below athletes from non-combat sports. Males and females were found to be ‘poor/very poor’ in the majority of SJFT factors. Female success rate was found to have very large relationships to jump variables (SJ r = 0.713; CMJ r = 0.794; CMJ-AS r = 0.718; all p<0.05). Male success rate was found to have very large relationships to SJFT factors (# of throws r = 0.732; SJFT index r = - 0.648; both p<0.05). These results indicate that MMA success is dependent on different physiological factors in each sex. These results may also highlight areas for concern in MMA athlete’s physiological performance standards.
Un acercamiento al ejercicio del Principio-Liberación de la ética dusseliana desde la lógica proposicional
Authors: Fuquen Amaya Andrés Esteban
Published: February 2025

This paper analyzes Enrique Dussel's ethics of liberation from a propositional logic perspective, evaluating the validity of its ethical-practical framework as a basis for the praxis of his philosophy of liberation. Initially, an outline of the fundamental principles and criteria that compose this ethics is provided. Subsequently, the framework is subjected to a basic logical review, revealing significant inconsistencies that could compromise its validity. Among the main observations, it is highlighted that dividing the framework into two strands is unnecessary and counterproductive, as it could be structured as a single practical and logically coherent framework. Furthermore, a deeper critique is posed regarding the assumption of transforming specific aspects of capitalism to reduce its victimizing effects, since this system, by its very nature, generates victims. It is concluded that total structural transformation is a prerequisite for any ethical process of liberation. Only after establishing a new system could the necessary adjustments be addressed to mitigate the new forms of oppression that may eventually emerge. Thus, it is argued that, from a logical perspective, revolution must be the unavoidable starting point of Dussel's framework.
Hemodynamic changes during off-pump versus on-pump cardiac surgeries
Authors: Siddique Abul B. M. , Taher Abu , Moral M. Salim , Ahmed Mohammed S. , Alam M. Hassnul , Harun-Ur-Rashid M.
Published: February 2025

Background: Coronary artery bypass grafting (CABG) is a vital procedure for treating coronary artery disease (CAD). Traditionally, CABG is performed with cardiopulmonary bypass (CPB), known as on-pump surgery, which can cause complications like systemic inflammatory response and organ dysfunction. The primary objective of this study was to compare the hemodynamic changes during off-pump and on-pump cardiac surgeries, focusing on heart rate, blood pressure, and other key intraoperative and postoperative parameters.
Methods: This prospective observational study at BSMMU (2021-2022) compared hemodynamic changes in 160 patients undergoing on-pump and off-pump cardiac surgeries. Data were collected preoperatively, intraoperatively, and postoperatively in the intensive care unit (ICU). Statistical analysis was performed using statistical package for the social sciences (SPSS), with t-tests and Chi-square tests applied for comparisons.
Results: The study compared 160 patients (80 on-pump, 80 off-pump). The off-pump group had a lower heart rate (72±8 versus 75±10 beats/min, p=0.045) and higher mean arterial pressure (88±11 versus 85±12 mmHg, p=0.032). ICU stay was shorter in the off-pump group (2.8±1.0 versus 3.5±1.2 days, p=0.027), as was total hospital stay (6.5±1.8 versus 8.5±2.3 days, p=0.015). Thirty-day mortality was 3.8% for on-pump and 2.5% for off-pump (p=0.112), with one-year mortality at 6.3% versus 3.8% (p=0.089).
Conclusions: This study demonstrates that off-pump cardiac surgery results in improved hemodynamic stability, reflected in lower heart rates and higher mean arterial pressure during surgery compared to on-pump surgery.
Early administration of hydrocortisone vitamin C and thiamine in adult patients with septic shock: a randomized controlled clinical trial
Authors: Jaiswal Shantanu , Singh Reena , Giri Richa , Gautam Shri Krishna , Singh Mahendra Pal
Published: February 2025

Background: Hydrocortisone, vitamin C and thiamine have been suggested as a possible treatment for sepsis and septic shock. However, many trials do not support their use therefore this RCT was conducted to evaluate the efficacy of early administration (within 12 hours of diagnosis) of triple therapy (hydrocortisone, vitamin C and thiamine) in patients of septic shock in north Indian population. The primary objective was to determine the effect of combination on all-cause mortality at day 14. Secondary objectives were change in sofa score at day 3 and day 7, time to shock reversal (in hours) and mean length of hospital stay.
Methods: This single centre double blinded RCT was conducted in LLR and Associated hospitals, Kanpur between June, 2023 and June, 2024. The patients were randomly assigned to either Interventional group (n=75) or PLACEBO group (n=75). Interventional group received inj. hydrocort 200 mg once a day, inj. vitamin C 1 gm iv 3 times a day, thiamine 200mg iv 2 times a day for 5 day or until ICU discharge, the patients were then followed up for 14 days.
Results: Delta sofa score at day 3 and 7 were not statistically significant (p values- 0.5, 0.241). Significant results were obtained in mean length of hospital stay (11.87 vs 14 days, p value 0.005) and Mean time to shock reversal (176.33 vs 204.40 hours, p value<0.001). Mortality at day 14 was lesser in the interventional group (34.67% vs 45.33%, p value 0.205, statistically insignificant).
Conclusions: Thus, in patients with septic shock early treatment (within 12 hours of diagnosis) with injection hydrocortisone, vitamin c and thiamine does not confer mortality benefit but it decreases the length of hospital stay and time to shock reversal.
Association of microalbuminuria with severity of coronary artery disease in diabetic patients: a cross-sectional study
Authors: Vara Ranjith , Khan M. Adnan Ali , Krishnamurthy Shreya , Konidena SriSahithi
Published: February 2025

Background: Microalbuminuria is recognized as a significant indicator of early cardiovascular problems and diabetic renal impairment. It is indicative of vascular and endothelial damage and could be predictive of coronary atherosclerosis. The purpose of this investigation is to stratify coronary angiographic features in individuals having type 2 diabetes mellitus (T2DM), microalbuminuria and suspected of suffering from ischemic heart disease.
Methods: The cross-sectional prospective study had been performed over two years. Individuals who had T2DM undergoing coronary angiography for suspected ischemic heart disease but no prior history of myocardial infarction were chosen for the investigation.
Results: The investigation involved coronary angiography for 77 individuals with T2DM suspected of suffering from ischemic heart disease. 61 (79%) of the 77 individuals had normoalbuminuria, and 16 (21%) had microalbuminuria. Six individuals with normal coronary arteries were in normoalbuminuria group, while none in the microalbuminuria group had normal coronary arteries, as determined by angiography. All diabetic patients exhibiting microalbuminuria had multiple coronary artery diseases (CAD), which is indicative of a severe condition.
Conclusions: Microalbuminuria has been demonstrated to predict a more severe form of CAD along with intricate and widespread coronary lesions in people suffering from T2DM. Chronic smokers and elderly people having T2DM are more affected. Microalbuminuria has been associated with a severe form of coronary disease in these individuals. It was discovered that individuals with microalbuminuria were prone to more severe diffuse illness, and many had smaller caliber arteries that would be difficult to revascularize.

INTRODUCCIÓN: En nuestra región, la mortalidad neonatal sigue siendo elevada en comparación con países desarrollados. Con los últimos avances y conocimientos en materia de neonatología se ha podido disminuir, sobre todo, si se cuenta con los recursos adecuados.
OBJETIVO: Establecer las principales causas de muerte en neonatos atendidos en la UCIN entre el año 2005 al 2021 de un hospital privado de tercer nivel y determinar las diferencias de la evolución de los diferentes pacientes a través de los años
MATERIALES Y MÉTODOS: Estudio retrospectivo, observacional, descriptivo y longitudinal en el que se analizaron y evaluaron recién nacidos vivos ingresados a Unidad de Cuidados Intensivos Neonatales de un hospital privado de tercer nivel, que posteriormente fallecieron entre el año 2005 y 2021. RESULTADOS: La sepsis es el primer lugar en mortalidad con una tasa de 13.63, la enterocolitis necrosante es la segunda causa con una tasa de 4.4, seguido de otras causas como malformaciones congénitas, hemorragias cerebrales, asfixia, etc.
CONCLUSIÓN: Es notable la disminución de la mortalidad de los pacientes que ingresan a la unidad de cuidados intensivos neonatales durante los últimos años, aun así, no podemos ignorar la oportunidad de mejorar en cuestión de calidad la atención brindada a estos pacientes hospitalizados en nuestro país, hay demasiadas áreas de oportunidad que podemos actualizar y de esta manera proporcionar intervenciones aún más efectivas.

INTRODUCCIÓN: Los pacientes con fibrosis quística (FQ) presentan una enfermedad hereditaria autosómica recesiva caracterizada por un desequilibrio de agua, electrolitos y moco en múltiples órganos, que se asocia una alta afluencia de células y mediadores inflamatorios persistentes. Evaluaciones recientes han empleado ácidos grasos esenciales (omega 3) como agentes inmunomoduladores, sin embargo, en la actualidad aún no se tiene suficiente evidencia para su recomendación en pacientes con FQ.
OBJETIVO: Evaluar los estudios clínicos aleatorizados que han empleado ácidos grasos omega-3 como terapia sobre la inflamación en pacientes con fibrosis quística.
MATERIAL Y MÉTODOS: Se realizó una revisión sistemática cualitativa de acuerdo con los elementos considerados para la planeación de una revisión sistemática por Cochrane, en la cual se incluyeron Estudios Clínicos Aleatorizados (ECA) doble o triple ciego con antigüedad menor a 10 años.
RESULTADOS: Tres ECA con buena calidad científica presentaron efectos positivos sobre biomarcadores inflamatorios. Los principales hallazgos involucraron una mejora en el perfil de ácidos grasos circulantes y eritrocitarios ((incremento en el ácido docosahexaenoico (DHA) y disminución del ácido araquidónico). Consecuentemente esta relación mejora múltiples indicadores como Interleucina-6 (IL-6) y elastasa leucocitaria humana. Las principales limitaciones involucran la carencia de un biomarcador específico para evaluar mejoras antiinflamatorias en la FQ. 
CONCLUSIÓN: La suplementación a largo plazo con DHA puede mejorar la inflamación en la fibrosis quística. La regulación de la actividad leucocitaria y perfil de ácidos grasos proinflamatorios parecen ser responsables de los efectos observados.

La terapia con células T con receptores de antígeno quiméricos (CAR-T, por sus siglas en ingles) es una de las innovaciones más prometedoras en el tratamiento del cáncer y otras enfermedades autoinmunes incluso infecciosas no solo de la infancia si no también en la edad adulta. Esta terapia consiste en la modificaciónn genética de linfocitos T del propio paciente para que puedan reconocer y destruir células tumorales de manera más eficiente. En los últimos años, esta técnica ha demostrado resultados prometedores especialmente en el tratamiento de ciertos tipos de leucemias y linfomas en población pediátrica. Su aplicación ha marcado un cambio de paradigma en la hemato oncología pediátrica, ofreciendo una alternativa para pacientes que no responden a los tratamientos convencionales. Recientemente el uso de celulas alogenicas esta ampliando su uso a otras áreas de la médicina como la inmunologia y la infectología entre otas, abiendo un sin numero de oportunidades en este nuevo campo de la terapia celular geneticamente modificada

Published: February 2025

El tumor teratoide/rabdoide atípico (AT/RT, siglas en inglés) es una neoplasia embrionaria de alto grado del sistema nervioso central (SNC), compuesta por células indiferenciadas que alternan con células rabdoides y con potencial para diferenciarse a lo largo de líneas neuroectodérmica, epitelial y mesenquimal. Genéticamente, estos tumores se caracterizan por la inactivación bialélica de SMARCB1 (INI1) o raramente de SMARCA4 (BRG1) u otros genes del complejo de remodelación de la cromatina1. El AT/RT leptomeníngeo difuso primario, que afecta a las leptomeninges sin evidencia de tumor intraaxial en encéfalo o médula espinal, es extremadamente raro. Presentamos un caso de AT/RT leptomeníngeo difuso primario con cuadro clínico que simuló neuritis óptica bilateral, neurorretinitis bilateral y vasculitis en una escolar diagnosticada en estudio post mortem.

Introduction: Evidence-Based Practice (EBP) has been widely disseminated in recent years; however, there is still need to be a gap its use in clinical practice. Objective: To identify the profile among gynecologists and urologists who work with pelvic injury disorders in Brazil and the barriers faced in implementing EBP. Methods: A descriptive observational study will evaluate the knowledge, skills, barriers, and facilitators of EBP implementation in clinical practice. A questionnaire was sent out via social media and completed using the Google Forms digital platform between August 2022 and January 2023. After obtaining the descriptive results, a regression analysis was carried out using the Poisson model. Results: Sixty-three responses from gynecologists and urologists with an average age of 44.81 (± 12.01) years. Of the participants, 87.8% use articles as a method of updating, and a further 62% point to using WhatsApp groups as a social network for professional information. Approximately 85.7% understand the application of research results in clinical practice, and 95.3% consider EBP necessary for their clinical practice. The study showed that those who declared a better command of the English language had a higher prevalence of the number of items indicating that they had carried out EBP. Conclusion: physicians working with PFD report that they apply EBP routinely, update their knowledge through scientific articles and social networks, and use databases regularly. However, the lack of command of the English language was a barrier to implementing EBP in professional clinical practice.

Background/Objective. Garlic (Allium sativum) is a crop of economic relevance in Mexico. Nuevo León stands out in production; however, in the municipality of Aramberri, post-harvest losses have been reported due to diseases of unknown etiology. The objective of this work was to identify the fungi associated with the postharvest deterioration of A. sativum bulbs in Aramberri, Nuevo León, Mexico and to evaluate their in vitro sensitivity to fungicides. Materials and Methods. From bulbs with evidence of deterioration and necrosis, fungi were isolated in PDA medium. Four isolates were identified by morphological analysis and one isolate from each morphological species was identified by molecular analysis. The pathogenicity of the four isolates on symptom-free bulbil was evaluated. In addition, in vitro susceptibility tests of the isolates to protective and systemic fungicides were performed. Fungicides were evaluated at three concentrations and mycelial growth reduction (MGR) and conidial germination inhibition (CGI) was estimated. Results. The fungi Alternaria embellisia and Penicillium allii were identified in association with A. sativum bulbs with postharvest deterioration. P. allii showed the ability to develop internal infections from wounds; A. embellisia only showed growth on wounds. There were significant differences (p <0.0001) in the effectiveness of fungicides on the two species. Propiconazole and copper hydroxide inhibited 100% MGR and CGI in both fungi, at all doses evaluated. Conclusion. P. allii is first reported as a causative agent of green garlic rot in Mexico. This study will serve as a basis for choosing control strategies and will contribute significantly to reducing economic losses in garlic production in this region.
