Resumen El carcinoma renal de células claras (CRCC) es una neoplasia maligna poco común que representa el 3% de todos los tumores malignos en adultos. Este tumor presenta una alta tendencia a desarrollar metástasis sincrónicas o metacrónicas en diferentes sitios anató micos. Aunque la metástasis en la vesícula biliar por CRCC es extremadamente rara, se han reportado casos esporádicos en la literatura médica. Presentamos el caso de una mujer de 78 años con antecedentes de carcinoma indiferenciado de cavum, carcinoma basocelular y CRCC en riñón derecho. Se sometió a nefrectomía radical. El análisis histopatológico confirmó el diagnóstico de CRCC sin invasión vascular ni ureteral. Dos años después, du rante el seguimiento, se detectó una lesión nodular en la vesícula biliar mediante tomografía computarizada. A pesar de la ausencia de síntomas, se decidió la resección quirúrgica. Se realizó colecistectomía laparoscópica sin complicaciones. El examen histopatológico confirmó la presencia de metástasis de CRCC en la vesícula biliar. La paciente evolucionó favorablemente encontrándose en seguimiento sin recurrencia. La metástasis vesicular por CRCC es extremadamente rara, pero los cirujanos deben considerarla en pacientes con antecedentes de CRCC. El diagnóstico diferencial prequirúrgico entre el carcinoma primario de vesícula biliar y la metástasis de CRCC puede ser desafiante y, a menudo, se confirma mediante el examen histopatológi co. La resección quirúrgica completa parece ser la mejor opción de tratamiento para lograr una supervivencia libre de enfermedad.

Abstract Clear cell renal cell carcinoma (ccRCC) is an uncom mon malignant neoplasm that accounts for 3% of all malignant tumors in adults. This tumor exhibits a high tendency to develop synchronous or metachronous me tastases in different anatomical sites. Although gallblad der metastasis from ccRCC is extremely rare, sporadic cases have been reported in the medical literature. We present the case of a 78-year-old woman with a history of undifferentiated nasopharyngeal carcinoma, basal cell carcinoma, and ccRCC in the right kidney. She un derwent radical nephrectomy. Histopathological analysis confirmed the diagnosis of ccRCC without vascular or ureteral invasion. Two years later, during follow-up, a nodular lesion was detected in the gallbladder through computed tomography. Despite the absence of symp toms, surgical resection was decided. Laparoscopic cho lecystectomy was performed without complications. Histopathological examination confirmed the presence of ccRCC metastasis in the gallbladder. The patient had a favorable outcome and is currently under follow-up without recurrence. Gallbladder metastasis from ccRCC is extremely rare, but surgeons should consider this possibility in patients with a history of ccRCC. Preoperative differential diagno sis between primary gallbladder carcinoma and ccRCC metastasis can be challenging and is often confirmed through histopathological examination. Complete sur gical resection is the best treatment option to achieve disease-free survival.

ABSTRACT: Current demographic and epidemiological changes will condition increased caries prevalence and incidence, specifically root caries lesions (RCLs) in the elderly. There will be a need, therefore, for therapeutic approaches with greater coverage and effectiveness. This article summarizes, in Spanish, the current available evidence leading to clinical recommendations for preventive, non-invasive, micro or minimally invasive and invasive interventions for the management of dental caries in older people, with special emphasis on RCLs. This publication is based on a consensus workshop, followed by an e-Delphi consensus process, conducted by a panel of experts nominated by the European Organization for Caries Research (ORCA), the European Federation of Conservative Dentistry (EFCD) and the German Federation of Conservative Dentistry (DGZ). The purpose of this article is to present the main conclusions reached in the ORCA/EFCD/DGZ consensus to allow a better dissemination of knowledge and the application of these concepts in clinical practice, guiding the correct decision-making for the disease management and the RCLs in the elderly.

RESUMEN: Los cambios demográficos y epidemiológicos actuales determinarán un aumento en la prevalencia e incidencia de caries, específicamente lesiones de caries radicular (RCLs, por sus siglas en inglés) en personas mayores, por lo que la necesidad de tratamiento de mayor cobertura y efectividad será también cada vez mayor. Este artículo resume en español la evidencia actual disponible acerca de las recomendaciones clínicas para las intervenciones preventivas, no invasivas, micro o mínimamente invasivas e invasivas para el manejo de la caries dental en personas mayores, con especial énfasis en RCLs. La presente publicación se basa en un taller de consenso, seguido de un proceso de consenso e-Delphi, realizado por un panel de expertos nominados por la Organización Europea para la Investigación en Caries (ORCA), la Federación Europea de Odontología Conservadora (EFCD) y la Federación Alemana de Odontología Conservadora (DGZ). El propósito de este artículo es presentar las principales conclusiones alcanzadas en el consenso de ORCA/EFCD/DGZ para permitir una mejor difusión del conocimiento y la aplicación de estos conceptos en la práctica clínica, orientando la correcta toma de decisiones en el manejo de la enfermedad y RCLs en las personas mayores.

Losartan potassium and hydrochlorothiazide are often combined in pharmaceutical formulations for the treatment of hypertension. Therefore, the determination of these compounds in a single run is highly desirable for rapid quality control applications. The present study describes an ultra-fast (ca. 85 injections h-1) and environmentally friendly method based on capillary electrophoresis (CE) with capacitively coupled contactless conductivity detection for simultaneous quantification of potassium, losartan and hydrochlorothiazide. Cation (potassium) and anions (losartan and hydrochlorothiazide) were analyzed in a single run using a background electrolyte composed by 10.0 mmol L-1 boric acid (pH = 9.0, adjusted with sodium hydroxide). The limits of detection were 4.0, 3.0 and 10.0 μmol L-1 for potassium, losartan and hydrochlorothiazide, respectively. The proposed method is simple, fast, with minimal waste generation, and accurate (recovery values between 98 and 102%). The results obtained with the CE method were statistically similar (95% confidence level) to those obtained by high-performance liquid chromatography (losartan and hydrochlorothiazide) and flame photometry (potassium).

ABSTRACT Geothermal energy is a renewable source that can assist in the thermal conditioning of constructed environments. The objective of this study was to analyze the heat transfer in a Red Latosol (Oxisol), in heat storage process, using two linear heat exchangers. The treatments were arranged in a 3 × 2 × 3 factorial scheme, corresponding to three temperature differentials between soil and water (5, 10 and 15 °C), two types of materials (PVC and copper) and three radial distances (10, 20 and 25 cm), with three replicates. Soil temperature variations were obtained continuously for a period of 12 hours using DS18B20 sensors. These variations were logarithmic as a function of heat transfer time and radial distance and linear as a function of the temperature differential between soil and water (θ). The temperature differential between soil and water was the main factor that influenced soil temperature variation, and the material employed was insignificant in this variation. The minimum distance between heat exchangers should be greater than 50 cm, and PVC pipes proved to be more attractive for use involving thermal exchange with the ground as they are more viable than copper and easier to implement.

RESUMO A energia geotérmica é uma fonte renovável que pode auxiliar no condicionamento térmico de ambientes construídos. O objetivo deste estudo foi analisar a transferência de calor em um Latossolo Vermelho (Oxisol), em processo de armazenamento de calor, utilizando dois trocadores de calor lineares. Os tratamentos foram dispostos em esquema fatorial 3 × 2 × 3, correspondendo a três diferenciais de temperatura entre solo e água (5, 10 e 15 °C), dois tipos de materiais (PVC e cobre) e três distâncias radiais (10, 20 e 25 cm), com três repetições. As variações de temperatura do solo foram obtidas continuamente por um período de 12 horas usando sensores DS18B20. Essas variações foram logarítmicas em função do tempo de transferência de calor e da distância radial, e lineares em função do diferencial de temperatura entre o solo e a água (θ). O diferencial de temperatura entre o solo e a água foi o principal fator que influenciou na variação da temperatura do solo, sendo que o material empregado foi insignificante nessa variação. A distância mínima entre os trocadores de calor deve ser maior que 50 cm, e os tubos de PVC se mostraram mais atrativos para uso envolvendo troca térmica com o solo por serem mais viáveis que os de cobre e mais fáceis de serem executados.

Abstract: The main objective of this research study is to determine whether perceived behavioral control has a moderating role in the influence of attitude toward entrepreneurship and subjective norms on entrepreneurial intention. The sample consists of 159 master of business administration (MBA) students from four Colombian universities. The methodological design is cross-sectional and explanatory and applies the partial least squares structural equation modeling (PLS-SEM). The results show that there is no evidence to suggest that perceived behavioral control moderates the relationship between attitude toward entrepreneurship and entrepreneurial intention. In addition, there is no evidence to infer that perceived behavioral control moderates the relationship between subjective norms and entrepreneurial intention. In conclusion, the current model of the theory of planned behavior provides no empirical support for explaining the entrepreneurial intention of MBA students from four different Colombian universities.

Resumen: El objetivo de esta investigación es determinar si el control del comportamiento percibido tiene un rol moderador en la influencia de la actitud hacia el emprendimiento y las normas subjetivas sobre la intención emprendedora. La muestra consiste en 159 estudiantes de maestría en administración de empresas (MBA) de cuatro universidades privadas colombianas en Bogotá. El diseño metodológico es explicativo-transversal y utiliza el modelo de ecuaciones estructurales con mínimos cuadrados parciales (PLS-SEM). Los resultados muestran que no hay evidencia para afirmar que el control del comportamiento percibido modera la relación entre la actitud hacia el emprendimiento y la intención emprendedora. Tampoco hay evidencia de que el control del comportamiento percibido modera la relación entre las normas subjetivas y la intención emprendedora. En conclusión, el modelo actual de la teoría de la conducta planeada no tiene respaldo empírico en la explicación de la intención emprendedora de estudiantes de cuatro programas de MBA de universidades colombianas.

RESUMEN La rotura espontánea de la vena ilíaca es una causa poco frecuente de hemorragia retroperitoneal exanguinante. Generalmente está asociada con un traumatismo y las lesiones iatrogénicas durante la cirugía de hemiabdomen inferior o pelviana. Ocurre con frecuencia del lado izquierdo y afecta indistintamente a la vena ilíaca común como a la externa. Con el objetivo de destacar las características clínicas e imagenológicas de esta infrecuente entidad, presentamos un caso fatal de rotura espontánea de la vena ilíaca externa izquierda. El tratamiento se basa en la reparación quirúrgica abierta o, en casos seleccionados, en la colocación de prótesis por vía endovascular. Es necesario un alto índice de sospecha, ya que el diagnóstico y el tratamiento tempranos son fundamentales para mejorar las altas tasas de morbimortalidad que conlleva esta entidad.

ABSTRACT Spontaneous rupture of the iliac vein is a rare cause of fatal retroperitoneal hemorrhage that is generally associated with trauma and iatrogenic injury during lower abdominal or pelvic surgery. It usually occurs in the left common and external iliac veins. We report a fatal case of spontaneous rupture of the left external iliac vein to emphasize the clinical and imaging characteristics of this rare condition. Treatment is based on open surgical repair or endovascular stenting in selected cases. High level of suspicion is essential for early diagnosis and treatment to improve the associated morbidity and mortality.

Abstract Background Despite representing the largest fraction of animal life, the number of insect species whose genome has been sequenced is barely in the hundreds. The order Dermaptera (the earwigs) suffers from a lack of genomic information despite its unique position as one of the basally derived insect groups and its importance in agroecosystems. As part of a national educational and outreach program in genomics, a plan was formulated to engage the participation of high school students in a genome sequencing project. Students from twelve schools across Chile were instructed to capture earwig specimens in their geographical area, to identify them and to provide material for genome sequencing to be carried out by themselves in their schools. Results The school students collected specimens from two cosmopolitan earwig species: Euborellia annulipes (Fam. Anisolabididae) and Forficula auricularia (Fam. Forficulidae). Genomic DNA was extracted and, with the help of scientific teams that traveled to the schools, was sequenced using nanopore sequencers. The sequence data obtained for both species was assembled and annotated. We obtained genome sizes of 1.18 Gb (F. auricularia) and 0.94 Gb (E. annulipes) with the number of predicted protein coding genes being 31,800 and 40,000, respectively. Our analysis showed that we were able to capture a high percentage (≥ 93%) of conserved proteins indicating genomes that are useful for comparative and functional analysis. We were also able to characterize structural elements such as repetitive sequences and non-coding RNA genes. Finally, functional categories of genes that are overrepresented in each species suggest important differences in the process underlying the formation of germ cells, and modes of reproduction between them, features that are one of the distinguishing biological properties that characterize these two distant families of Dermaptera. Conclusions This work represents an unprecedented instance where the scientific and lay community have come together to collaborate in a genome sequencing project. The versatility and accessibility of nanopore sequencers was key to the success of the initiative. We were able to obtain full genome sequences of two important and widely distributed species of insects which had not been analyzed at this level previously. The data made available by the project should illuminate future studies on the Dermaptera.

Resumen El murciélago magueyero mayor (Leptonycteris nivalis) es el murciélago nectarívoro más grande de América y una de las tres especies nectarívoras migratorias de México. Se encuentra catalogada como especie ’En Peligro de Extinción’ en Estados Unidos y como ’Amenazada’ bajo la ley federal mexicana. A pesar de que L. nivalis tiene una amplia distribución en el país, solamente se ha documentado un refugio de apareamiento de esta especie: “La Cueva del Diablo”, localizada en el estado de Morelos, en el centro de México. En 1994, con la participación de investigadores origen mexicano y de Estado Unidos, a través de la USFWS, se elaboró el Plan de Recuperación de L. nivalis, donde se identificaron las acciones más urgentes y necesarias para su recuperación. Dentro de dichas acciones se encuentran la localización y protección de refugios. En este estudio identificamos áreas potenciales de distribución de refugios de apareamiento en el centro de México, realizamos visitas a las zonas predichas por los análisis para confirmar la presencia de L. nivalis y realizamos una evaluación del estado reproductivo de los individuos. Para los análisis realizamos modelos de nicho ecológico utilizando los algoritmos Maxent, Bioclim y GARP y generamos un mapa consenso de las zonas potenciales de distribución. Adicionalmente, realizamos un análisis de distancias euclidanas multidimensionales para identificar las zonas ecológicamente más similares a la “Cueva del Diablo”. Como resultado identificamos áreas potenciales en los estados de Morelos, Puebla y el Estado de México. Visitamos 17 cuevas distribuidas en 10 localidades y encontramos individuos de L. nivalis por dos años consecutivos en la “Cueva de los Coyotes”, localizada en el suroeste del Estado de México. Capturamos 18 individuos en total, incluyendo una hembra preñada. La ubicación de un refugio ocupado por la especie L. nivalis, y particularmente por una hembra preñada, nos permite reflexionar sobre las dinámicas reproductivas de la especie. En ese sentido, las poblaciones reproductivas podrían estarse separando en pequeñas colonias de apareamiento, a parte de “La Cueva del Diablo”, o las hembras preñadas podrían estarse moviendo hacia otros refugios para pasar el resto del inverno. Con el mejoramiento de las técnicas utilizadas en este estudio será posible encontrar y proteger refugios de apareamiento adicionales de L. nivalis.

Abstract The Mexican Long-nosed bat (Leptonycteris nivalis) is the largest nectarivorous species in the New World, and one of three migratory nectarivores in Mexico. It is considered an ‘Endangered Species’ under the U.S. Endangered Species Act and ‘Threatened’ by the Mexican Federal List of Endangered Species. In 1994, a Recovery Plan was developed by the USFWS with the participation of Mexican and American researchers, and the most urgent actions to ensure the species protection were identified. Locating and protecting roosts are among the most urgent tasks recognized. With this study, we aimed to identify the most suitable areas potentially holding additional mating roosts of Leptonycteris nivalis, and we conducted surveys of these areas to confirm its presence, and to assess the reproductive state of individuals. We used Maxent, the Genetic Algorithm for Rule-set Production (GARP), and Bioclim algorithms to generate an agreement map of the potential distribution of additional mating roosts, and we implemented a Euclidian multidimensional distances analysis to identify ecologically similar regions to “La Cueva del Diablo”, the only mating roost known for the species. We identified suitable areas in the states of Morelos, Puebla and the State of Mexico. We visited seventeen caves distributed in ten different localities in these areas. For two consecutive years, we found the species in a cave called: “La Cueva de los Coyotes”, located in the State of Mexico, where we captured eighteen individuals, including a pregnant female. The location of an unknown roost so far, occupied by individuals of L. nivalis, and among them a pregnant female, allows us to reflect about the reproductive dynamics of the species. In that sense, reproductive populations may be splitting into smaller colonies to mate, other than “La Cueva del Diablo”, or pregnant females might me moving to additional and nearby roosts to spend the rest of the winter season. Using these tools and further refinements we may be able to locate additional mating roosts, thus, providing more possibilities for the application of conservation measures for the protection of the species.

Abstract This study described the growth, morphometric, biomechanical, and chemical properties of the femur, tibiotarsus, and tarsometatarsus of European and Japanese quail. Analyses were performed at 13 and 15 days of incubation, at hatch, and at 4, 7, 10, 14, 21, 28, and 35 days post-hatch (n=6/subspecies/period). Bone specimens were analyzed by cone-beam computed tomography, biomechanical assays, chemical analyses, and histomorphometry. Variables were fitted by the Gompertz function and its derivative or assessed using the analysis of variance. Analysis of the derivative of Gompertz curves showed that the growth behavior of the tarsometatarsal bone was similar between quail subspecies, and the femur and tibiotarsus of European quail increased first in width and then in length, whereas the opposite occurred in Japanese quail. There was an interaction between quail subspecies and days of growth on femoral, tarsometatarsal, and tibiotarsal bone densities. Femoral and tibiotarsal cross-sectional areas were influenced by the interaction of quail subspecies and day of growth. Interaction effects were significant for breaking strength and phosphorus percentage. European and Japanese quail have different femoral and tibiotarsal growth patterns, especially in the first few days after hatching, whereas tarsometatarsal growth is similar between subspecies.

ABSTRACT CROPWAT is a model that uses water balance to study the water factor and productivity in production systems. In this sense, this study aimed to calibrate the CROPWAT for modeling rainfed and irrigated soybean production systems. Climate and soil data from a soybean-producing region in the south of Mato Grosso do Sul, Brazil, were used to implementing simulations in nine agricultural years, and crop shortfalls were calculated and compared with reference data. Statistical indices were applied to evaluate the performance of the model in its calibration. For validation, two field trials with 12 cultivars were implemented under irrigation and rainfed and the mean productivity in each water management was compared with the CROPWAT estimate by Student’s t-test. Accuracy (r) was 0.976 (“very strong”), precision (r2) was equivalent to 95.3%, and the indices of agreement (d) and performance (c) were considered excellent (0.95 and 0.93, respectively) in the calibration. Validation demonstrated that the hypothesis that CROPWAT correctly estimated soybean productivity under irrigated and rainfed systems cannot be rejected at 1 or 5% significance levels.

ABSTRACT Introduction: The disease caused by SARS-CoV-2 has become a significant public health issue. 5 % of the patients required endotracheal intubation due to acute hypoxemic respiratory failure, leading to an increased number of consultations for tracheal stenosis. This work was done with the aim of presenting the results of tracheal resection in patients with post-COVID-19 stenosis. Material and methods: Analytical, prospective, observational study. 11 patients were included. The preoperative and postoperative evaluation was the same for all patients. Post-surgical ventilation and phonation were assessed up to 30 days. The Clavien and Dindo classification was used to grade post-surgical complications, with follow-up extended up to 60 post-surgical days. Statistical analysis: the Wilcoxon test was used to compare the results. Results: 27.2 % of the patients had postoperative complications. The comparison of pre- and postoperative ventilation (p < 0.05) was statistically significant, with improvement in the postoperative period. When comparing pre- and postoperative fiberoptic bronchoscopy (tracheal lumen diameter), the result was also statistically significant (p < 0.05). Conclusion: The results obtained are similar to those expressed in the literature. Tracheal resection is a safe and effective procedure and should be considered as first-line treatment for tracheal stenosis.

RESUMEN Introducción: La enfermedad por SARS-CoV-2 se convirtió en un importante problema de salud pública. El 5 % de los pacientes requirió intubación endotraqueal por insuficiencia respiratoria aguda hipoxémica, y se generó un aumento de consulta por estenosis traqueal. Se realizó el trabajo con el objetivo de expresar los resultados de la cirugía de resección traqueal en pacientes con estenosis post COVID 19. Material y métodos: Estudio prospectivo, observacional, analítico. Se incluyeron 11 pacientes. La evaluación prequirúrgica y postquirúrgica fue la misma en todos los pacientes. Se valoró en el postquirúrgico la ventilación y la fonación hasta los 30 días. Se utilizó la clasificación de Clavien y Dindo para calificar a las complicaciones post-quirúrgicas, con seguimiento hasta los 60 días postquirúrgicos. Análisis estadístico: se aplicó prueba de Wilcoxon para comparar los resultados. Resultados: El 27.2 % de los pacientes tuvieron complicaciones postquirúrgicas. Fue estadísticamente significativa la comparación de la ventilación entre el prequirúrgico y el postquirúrgico (p<0.05) con mejoría en el postquirúrgico. Al comparar la fibrobroncoscopía prequirúrgica con la postquirúrgica (diámetro de la luz traqueal) también el resultado fue estadísticamente significativo (p <0.05). Conclusión: Los resultados obtenidos son similares a los expresados en la literatura. La cirugía de resección traqueal es un procedimiento seguro y efectivo y debe ser considerada como tratamiento de primera línea para la estenosis traqueal.

In Brazil, native forests and replanted forests are poorly managed, and there is concern about reusing plastic residues as well. These two factors play a significant role in the impacts on the environment in the past decades. In this study, the influence of polystyrene (PS) waste partially replacing polyurethane (PUR) as a binder for wood particles (Pinus taeda L. and Eucalyptus saligna) was examined on the physicomechanical and thermal properties of homogeneous particleboards. For the production of particleboard composite, the moisture content of wood particles was set at 2%. A variety of physicomechanical characteristics were evaluated, including density, moisture content, swelling in thickness after 24 hours of immersion in water, rupture modulus (MOR) and elasticity modulus (MOE). Increasing PS relative to PUR decreased MOR and MOE properties in particleboard composite specimens. Thermal analysis shows that replacing PUR with PS in particleboard composite specimens has not adversely affected the thermal stability, and even less its thermal profile of specimens. ABNT NBR standards were exceeded by particleboard composite-based panels, but ANSI standards were met, indicating their potential application. As a result of this study, PS waste could be used as a binder for particleboards and composite materials manufactured from pinus and eucalyptus wood chips in place of PUR.
