Abstract (Introduction): The search for techniques and methods for managing sludge generated during wastewater treatment is necessary to ensure sustainable sanitation in the medium term in Latin America. An interesting approach involves converting sludge into a biosolid usable in agriculture through alkaline sanitization. (Objective): We evaluated this technique’s efficacy and economic and environmental viability for obtaining an agriculturally usable type A biosolid from municipal wastewater treatment plant (WWTP) sludge. (Methodology): To this end, the efficacy in reducing microbiological parameters was experimentally tested at the laboratory scale using quicklime, for anaerobic and aerobic WWTP sludge. The experimental results fed a benefit/cost analysis model and a life cycle assessment. (Results): It was confirmed that applying a 40 % lime dose allowed the obtention of a type A biosolid with non-detectable concentrations of pathogenic microorganisms, which remained in that condition for more than 30 days. Additionally, the benefit/cost and life cycle analyses concluded that this option would be more attractive than sludge disposal in a landfill, due to the corresponding savings in chemical compounds (fertilizers, agricultural lime). (Conclusions): Therefore, alkaline sanitization can be considered suitable for WWTP sludge management. Its application on a larger scale should be further investigated in the country and the Latin-American region, considering the risk associated to the presence of heavy metals too.

Resumen (Introducción): La búsqueda de técnicas y modelos de gestión del lodo generado durante el tratamiento de las aguas residuales es necesaria para garantizar un saneamiento sostenible a mediano plazo en América Latina. Una vía interesante consiste en convertir el lodo en un biosólido aprovechable en la agricultura por medio de la higienización alcalina. (Objetivo): Se evaluó la eficacia y la viabilidad económica y ambiental de esta técnica para la obtención de un biosólido tipo A aprovechable en la agricultura a partir de lodo de planta de tratamiento de aguas residuales (PTAR) ordinaria. (Metodología): Para ello se probó experimentalmente en escala de laboratorio la eficacia en el decaimiento de parámetros microbiológicos higienizados con cal viva, usando lodo anaeróbico y aeróbico de PTAR. Los resultados experimentales alimentaron un modelo de análisis de beneficio/costo y de ciclo de vida. (Resultados): Pudo corroborarse que la aplicación de dosis de cal de 40 % permitió obtener un biosólido tipo A con concentraciones de microorganismos patógenos no detectables, lo cual se mantuvo en esa condición por más de 30 días. Además, el análisis de beneficio/costo y de ciclo de vida permitieron concluir que esta opción sería más atractiva que la disposición del lodo en un relleno sanitario, debido al ahorro correspondiente en compuestos químicos (fertilizantes o cal agrícola) derivado de su aprovechamiento. (Conclusiones): Por lo tanto, la técnica de higienización alcalina puede considerarse como adecuada para la gestión del lodo de PTAR y su aplicación a mayor escala debe investigarse en mayor detalle en el país y la región latinoamericana, considerando también el riesgo de presencia de metales pesados en este subproducto.

ABSTRACT Purpose: To determine the clinical outcomes in patients after type 1 Boston keratoprosthesis surgery and the significance of ultrasound biomicroscopy imaging for postoperative follow-up. Methods: This retrospective analysis included 20 eyes of 19 patients who underwent corneal transplantation with type 1 Boston keratoprosthesis between April 2014 and December 2021. Data on patient demographics, preoperative diagnosis, visual acuity, and postoperative clinical findings were analyzed. Results: Type 1 Boston keratoprosthesis implantation resulted in intermediate- and long-term positive outcomes. However, blindness and other serious complications such as glaucoma, retroprosthetic membrane formation, endophthalmitis, or retinal detachment also occurred. The use of ultrasound biomicroscopy imaging allowed for better evaluation of the back of the titanium plate, anterior segment structures, and the relationship of the prosthesis with surrounding tissues, which provided valuable postoperative information. Conclusion: Regular lifetime monitoring and treatment are necessary in patients who undergo Boston type 1 keratoprosthesis implantation for high-risk corneal transplantation. ultrasound biomicroscopy imaging can be a valuable imaging technique for the evaluation of patients with Boston type 1 keratoprosthesis, providing important information on anterior segment anatomy and potential complications.

Resumen Objetivo: desarrollar un método para la cobertura delta de portafolios de opciones europeas listadas con base en la teoría del cálculo conformable que mejora la precisión de las predicciones usando la aproximación de primer orden. Metodología: permitimos que la primera derivada en el modelo clásico de Black-Scholes-Merton tenga un orden fraccional 0 ≤ α ≤ 1 y calculamos la delta correspondiente de un portafolio como función de este parámetro conformable. Resultados: aplicando este método a un portafolio conformado de ocho opciones europeas listadas sobre el índice SPX, encontramos que la cobertura conformable genera predicciones más precisas, en promedio, que la cobertura tradicional. Limitaciones: este método es aplicable solamente a la cobertura delta (hedging) de opciones europeas. Originalidad: esta es la primera aplicación exitosa del cálculo conformable a la cobertura delta en opciones europeas. Conclusiones: la aplicación del cálculo conformable permite mayor flexibilidad en la aproximación local implícita en la cobertura delta de portafolios de acciones europeas y se ofrece como una metodología novel y de mayor precisión que la tradicional.

Abstract Objective: we aim to develop a method for delta hedging portfolios of European options based on the theory of conformable calculus which improves accuracy of risk management of listed options in a first-order approximation. Methodology: we allow the time derivative in the classic Black-Scholes-Merton model to have a fractional order 0 ≤ α ≤ 1 and calculate the corresponding delta of a portfolio of listed options as a function of this conformable parameter. Results: applying this method to a portfolio consisting of eight European options on the SPX index, we find that conformable delta hedging offers more accurate average predictions than classical delta hedging. Limitations: this method is applicable for delta hedging in European options only. Originality: this is the first successful application of conformable calculus to delta hedging in European options. Conclusions: application of Conformable Calculus allows for a greater flexibility in the local approximation to price in delta-hedging European options and offers a new and more precise methodology to this objective.

Abstract Introduction: Almost 800 female deaths occur daily due to preventable causes associated with complications during or after pregnancy or childbirth, equivalent to two maternal deaths per minute. Objective: To develop a nursing care process for a pregnant woman who suffered from hyperthyroidism using diagnostic taxonomies, results and nursing interventions with a focus on Orem's theory. Methodology: Case study of a pregnant woman treated in a second level care hospital, the Orem assessment guide was used, developing the stages: assessment, diagnosis, planning, execution and evaluation, individualized care plans were designed and executed. Privacy was protected by omitting identity, respecting the rights and well-being of the participant. Results: The risk conditioning factor that compromised the health of the mother-child binomial gave way to care planning aimed at the process of ineffective motherhood and ineffective self-management of health, establishing interventions such as high-risk pregnancy care and teaching the process of illness and prescribed medications, an improvement was obtained in the patient's health status, which allowed her discharge and adequate management of the high-risk pregnancy. Conclusion: The nursing care process exposed the context in which the pregnant woman with known uncontrolled pathology is admitted, which compromised maternal-fetal well-being. Nursing education is required to promote preconception maternal health for future pregnancies.

ABSTRACT Objectives: To evaluate the safety and effectiveness of robot-assisted radical cystectomy (RARC), laparoscopic radical cystectomy (LRC), and open radical cystectomy (ORC) in bladder cancer. Methods: A literature search for network meta-analysis was conducted using international databases up to February 29, 2024. Outcomes of interest included baseline characteristics, perioperative outcomes and oncological outcomes. Results: Forty articles were finally selected for inclusion in the network meta-analysis. Both LRC and RARC were associated with longer operative time, smaller amount of estimated blood loss, lower transfusion rate, shorter time to regular diet, fewer incidences of complications, and fewer positive surgical margin compared to ORC. LRC had a shorter time to flatus than ORC, while no difference between RARC and ORC was observed. Considering lymph node yield, there were no differences among LRC, RARC and ORC. In addition, there were statistically significant lower transfusion rates (OR=-0.15, 95% CI=-0.47 to 0.17), fewer overall complication rates (OR=-0.39, 95% CI=-0.79 to 0.00), fewer minor complication rates (OR=-0.23, 95% CI=-0.48 to 0.02), fewer major complication rates (OR=-0.23, 95% CI=-0.68 to 0.21), fewer positive surgical margin rates (OR=0.22, 95% CI=-0.27 to 0.68) in RARC group compared with LRC group. Conclusion: LRC and RARC could be considered as a feasible and safe alternative to ORC for bladder cancer. Notably, compared with LRC, RARC may benefit from significantly lower transfusion rates, fewer complications and lower positive surgical margin rates. These data thus showed that RARC might improve the management of patients with muscle invasive or high-risk non-muscle invasive bladder cancer.

ABSTRACT Introduction: The ureteral access sheath (UAS) is a medical device that enables repeated entrance into the ureter and collecting system during retrograde intrarenal surgery (RIRS). Its impact on stone-free rates, ureteral injuries, operative time, and postoperative complications remains controversial. Therefore, we performed a systematic review and meta-analysis comparing RIRS with versus without UAS for urolithiasis management. Purpose: To compare outcomes from retrograde intrarenal surgery (RIRS) for stone extraction with or without ureteral access sheath (UAS); evaluating stone-free rate (SFR), ureteral injuries, operative time, and postoperative complications. Materials and Methods: We systematically searched PubMed, Embase, and Cochrane Library in June 2024 for randomized controlled trials (RCTs) evaluating the efficacy and safety outcomes of UAS use in RIRS for urolithiasis treatment. Articles published between 2014 and 2024 were included. Pooled risk ratios (RRs) and mean differences (MDs) were calculated for binary and continuous outcomes, respectively. Results: Five RCTs comprising 466 procedures were included. Of these, 246 (52.7%) utilized UAS. The follow-up ranged from 1 week to 1 month. UAS reduced the incidence of postoperative fever (RR 0.49; 95% confidence interval [CI] 0.29–0.84; p=0.009), and postoperative infection (RR 0.50; 95% CI 0.30–0.83; p=0.008). There were no significant differences between groups in terms of SFR (RR 1.05; 95% CI 0.99–1.11; p=0.10), ureteral injuries (RR 1.29; 95% CI 0.95–1.75; p=0.11), operative time (MD 3.56 minutes; 95% CI −4.15 to 11.27 minutes; p=0.36), or length of stay (MD 0.32 days; 95% CI −0.42 to 1.07 days; p=0.40). Conclusion: UAS leads to a lower rate of post-operative fever and infection. However, UAS did not significantly reduce or increase the SFR or the rate of ureteral injuries during RIRS for patients with urolithiasis. The use of UAS should be considered to decrease the risk of infectious complications, particularly in those who may be at higher risk for such complications.

Abstract Introduction. Livestock farming with Creole cattle is practiced in rural areas with challenging characteristics for species management. Objective. To describe the production system and the socio-cultural and technical-economic factors affecting the production of Nunkiní Creole cattle (Bos taurus). Materials and methods. The study was conducted from November 2020 to October 2021 in nine livestock production units of Nunkiní, Calkiní municipality, Campeche, Mexico. Information was obtained from an interview form with social, cultural, technical, and economic study variables, applied to selected producers. Data were analyzed using descriptive statistics and ANOVA. Results. Livestock farming was carried out by men (100 %), with an average age of 58.44 years. The average years of experience were 34.61. Younger producers had higher levels of education and less experience, and were responsible for the production units of higher technological levels. The size of the livestock production unit ranged from five to twenty-two cattle (average of 14). Feeding management followed a transhumance scheme, with cattle being free-ranging on ejido lands and from May to December and semi-stabled from January to April, grazing on cultivated pastures and supplemented with agricultural residues. With the zootechnical management implemented by the producers, an average pregnancy rate of 83 % was achieved. The main product marketed was fresh meat in cuts and direct sale to consumers, with an average price of 2.675 USD$/kg. Conclusion. It is traditional extensive system that takes advantage of the common use of grasslands. It involves experienced but older producers, with small investments, and serves to strengthen their family economy. This activity is threatened by the lack of revaluation of Creole cattle and the introduction of exotic breeds in the area to maximize production.

Resumen Introducción. La ganadería con bovinos criollos se práctica en espacios rurales con características difíciles para el manejo de las especies. Objetivo. Describir el sistema productivo y los factores socioculturales y técnico-económicos que afectan la producción del bovino criollo de Nunkiní (Bos taurus). Materiales y métodos. El estudio se realizó entre noviembre del 2020 a octubre del 2021, en nueve unidades de producción pecuarias de Nunkiní en el municipio de Calkiní, Campeche, México. La información se obtuvo de una cédula de entrevista con variables de estudio sociales, culturales, técnicas y económicas, aplicada a productores seleccionados. Los datos se analizaron mediante estadística descriptiva y ANDEVA. Resultados. La crianza del ganado la realizaron hombres (100 %), con edad promedio de 58,44 años. Los años de experiencia promedio fueron de 34, 61. Los productores jóvenes tuvieron mayor escolaridad y menor experiencia, y se encargaron de las unidades de producción de mayor nivel tecnológico. El tamaño de la unidad de producción pecuaria varió de cinco a veintidós bovinos (media de 14). El manejo alimenticio tuvo un esquema de trashumancia, donde de mayo a diciembre estuvieron libres en tierras ejidales y de enero a abril se manejaron semiestabulados, con pastoreo en potreros cultivados y suplementados con residuos agrícolas. Con el manejo zootécnico implementado por los productores, se obtuvo un promedio de 83 % de preñez. El producto principal comercializado fue carne fresca en cortes y venta directa al consumidor, con un precio promedio de 2,675 USD$/kg. Conclusión. Es un sistema tradicional extensivo que aprovecha el uso común de los agostaderos. Con productores de experiencia, pero de edad avanzada, de pequeña inversión y le sirve para fortalecer su economía familiar. Dicha actividad se ve amenazada por la falta de revalorización del bovino criollo y la introducción de razas exóticas en la zona para maximizar la producción.

Abstract Introduction. Pesticides are used to control pests and diseases in agricultural activities. Improper management of these products poses a potential risk to human health and the environment. Objective. To evaluate the (eco)toxicological pressure exerted by synthetic pesticides on tobacco crops (Nicotiana tabacum) in the province of Sancti Spíritus, Cuba. Materials and methods. A database from the Provincial Directorate of Plant Health for the period 2016-2019 was used, where the pesticides assigned to the province for this crop were compared with those reported by interviewed farmers. The dual indicator POCER was used to obtain the results, determining the pressure exerted by different pesticides and their harmful reference on humans and the environment. Results. The trend in pesticide consumption (summarized in tables and graphs) showed 50 % decrease, corresponding to the country’s crop protection policy. Farmers mentioned the use of authorized and unauthorized active ingredients in the conducted surveys, and sixteen high-risk active ingredients were detected in the analyzed samples. Evaluating the POCER results and analyzed samples, a significant (eco)toxicological pressure was observed on both the environment and human health, exerted by a group of high-toxicity active ingredients used in tobacco cultivation in the province. Conclusion. Using the dual indicator POCER provides an evaluation of the (eco)toxicological pressure exerted by synthetic pesticides used in the tobacco cultivation (Nicotiana tabacum) in the province of Sancti Spíritus, Cuba, for the study period.

El manejo inadecuado de estos productos constituye un riesgo potencial para la salud humana y el medio ambiente. Objetivo. Evaluar la presión toxicológica (eco) ejercida por los plaguicidas sintéticos en los cultivos de tabaco (Nicotiana tabacum) en la provincia de Sancti Spíritus, Cuba. Materiales y métodos. Se utilizó una base de datos de la Dirección Provincial de Sanidad Vegetal para el período 2016-2019, donde se tomaron los plaguicidas asignados a la provincia para este cultivo y se compararon con los declarados por los agricultores entrevistados. Para la obtención de los resultados se utilizó el indicador dual POCER, que determinó la presión ejercida por los diferentes plaguicidas y su referencia nociva sobre el ser humano y el medio ambiente. Resultados. La tendencia del consumo de plaguicidas (resumida en tablas y gráficos) mostró una disminución del 50 %, que corresponde a la política de protección de los cultivos del país. Los agricultores mencionaron el uso de ingredientes activos autorizados y no autorizados en las encuestas realizadas, y en las muestras analizadas se detectaron dieciséis ingredientes activos de alto riesgo. Al evaluar los resultados de POCER y muestras analizadas se observó que existe una gran presión (eco)toxicológica tanto para el medio ambiente como para la salud humana ejercida por un grupo de ingredientes activos de alta toxicidad utilizados en el cultivo de tabaco de la provincia. Conclusión. Con la utilización del indicador dual POCER, se obtiene una evaluación de la presión (eco)toxicológica ejercida por los plaguicidas sintéticos utilizados en el cultivo del tabaco (Nicotiana tabacum) en la provincia de Sancti Spíritus, Cuba para el período de estudio.

ABSTRACT The mangroves are exposed to threats such as sea level rise, coastal erosion, increase in the frequency and intensity of extreme events, in addition to socioeconomic pressures. This study aimed to carry out a vulnerability and risk climate analysis for the Colombian mangrove socioecosystem. 22 threat indicators, eight of sensitivity and 18 of adaptive capacity were used, and through multivariate numerical analysis, the vulnerability and climate risk indices for Colombian Pacific and Caribbean mangroves were generated. The mangroves that presented the highest risk in the Caribbean were located in the Manaure, Tubará and, Puerto Escondido municipalities, while in the Pacific these high-risk areas were located on the southern coast in the Olaya Herrera, Francisco Pizarro, and La Tola municipalities, and in the northern coast in the Bahía Solano municipality. The threat indicators that captured the greatest variability in the analysis were: sea level rise, change in the coastline, change in water supply, change in mangrove coverage due to change in the coastline, change in temperature and precipitation due to El Niño and La Niña, and human footprint. These results are input for climate management of mangroves in Colombia and will contribute to the National Mangrove Program. Likewise, it can contribute to the National Mangrove Restoration Plan, the Nationally Determined Contribution of Colombia (NDC), the Long-Term Climate Strategy of Colombia E 2050, and the Territorial Plans for Climate Change Adaptation of the states and municipalities.

RESUMEN Los manglares están expuestos a amenazas como el aumento del nivel del mar, la erosión costera, el aumento de la frecuencia e intensidad de eventos extremos, además de presiones socioeconómicas. Este estudio tuvo como objetivo realizar un análisis de vulnerabilidad y riesgo climático para el socioecosistema de manglar de Colombia. Se utilizaron 22 indicadores de amenaza, 8 de sensibilidad y 18 de capacidad adaptativa; mediante un análisis numérico multivariado se generaron los índices de vulnerabilidad y riesgo climático para los manglares del Pacífico y del Caribe de Colombia. Los manglares que presentaron mayor riesgo en el Caribe se ubicaron en los municipios de Manaure, Tubará y Puerto Escondido, mientras que en el Pacífico estas áreas de alto riesgo se ubicaron en la costa sur, en los municipios de Olaya Herrera, Francisco Pizarro y La Tola, y en la costa norte de Bahía Solano. Los indicadores de amenaza que capturaron la mayor variabilidad del análisis fueron: el aumento del nivel del mar, el cambio en la línea de costa, el cambio en la oferta hídrica, el cambio en la cobertura de manglares por cambio en la línea de costa, el cambio en la temperatura y la precipitación debido a El Niño y La Niña, y la huella humana. Estos resultados son un insumo para la gestión climática de los manglares en Colombia y contribuirán al Programa Nacional de Manglares. Asimismo, podrán contribuir al Plan Nacional de Restauración de Manglares, la Contribución Nacionalmente Determinada de Colombia (NDC), la Estrategia Climática de Largo Plazo de Colombia E2050, y los Planes Territoriales de Adaptación al Cambio Climático de los departamentos y municipios.

Resumen Durante la valoración preanestésica de la paciente obstétrica, es fundamental evaluar la condición cardiovascular basal de la paciente, identificar riesgos potenciales y facilitar modificaciones conductuales para desarrollar una estrategia de manejo individualizada, dirigida a minimizar las complicaciones. La ecografía cardíaca a la cabecera del paciente (POCUS) es un instrumento valioso para evaluar la morfología y la función del corazón antes de un procedimiento quirúrgico. El POCUS cardiaco no está diseñado para sustituir a la ecocardiografía transtorácica formal, que corresponde al área de anestesiología cardiovascular y a la cardiología. Sin embargo, cuando se usa en conjunto con la anamnesis, el examen físico, el electrocardiograma y los resultados de exámenes de laboratorio previos, el POCUS cardiaco es un complemento valioso dentro del arsenal diagnóstico de los anestesiólogos. Permite la visualización directa del corazón y de los grandes vasos, con beneficios adicionales de velocidad, disponibilidad y bajo riesgo para la paciente. El objetivo del presente manuscrito es explorar y describir las ventajas del POCUS cardiaco durante el periodo preanestésico en pacientes obstétricas y su valor potencial para los anestesiólogos, a través de la identificación de condiciones eventualmente peligrosas que pudieran requerir un manejo preoperatorio individualizado.

Abstract During the preanesthetic assessment of the obstetric patient, it is critical to assess the patient's cardiovascular baseline condition, identify any potential risks, and facilitate behavioral modification to develop an individualized management strategy aimed at minimizing complications. Cardiac point-of-care ultrasound (POCUS) is a valuable instrument for assessing the morphology and function of the heart prior to surgery. Cardiac POCUS is not designed to replace comprehensive transthoracic echocardiography, which is the realm of cardiovascular anesthesiology and cardiology. However, when used in conjunction with anamnesis, physical examination, electrocardiogram, and previous laboratory results, cardiac POCUS is a valuable adjunct in the diagnostic toolbox of anesthesiologists. It allows for direct visualization of the heart and great vessels, with added benefits of speed, availability, and low risk for the patient. The purpose of this manuscript is to explore and describe the advantages of cardiac POCUS in the preanesthetic period of obstetric patients and its potential value for anesthesiologists through the identification of potentially hazardous conditions that may require individualized preoperative management.

Abstract The research analyzes the variables that influence the strengthening of business and tax culture through knowledge management. Methodologically, it is a study with a qualitative and analytical approach. The study highlights the importance of knowledge management as a catalyst for improving organizational culture and tax compliance in companies. Variables such as effective communication allow the organization to improve tax and administrative management through the individual knowledge of each employee. The acquisition of skills and knowledge through training and education strengthens the resilience of individuals to regulatory changes. Technology, used as a management and process optimization tool, reduces error variability while increasing efficiency and performance. Teamwork in the execution of tasks facilitates more efficient planning and optimal allocation of individual responsibilities. Finally, by implementing a risk management approach, it is possible to exercise greater diligence in the early detection of errors and minimize their impact on the ongoing business development context.

Summary: Avocado is a fruit (Persea americana), that has increased its consumption worldwide. Mexico is the main producer and exporter of avocado in the world, representing more than 30% of the world harvest, of which 73.2% of the total avocado production in Mexico was concentrated in the state of Michoacán. In the state of Michoacán, there is a constant production of avocado fruit throughout the year, but this production is affected by the variation in climate, water management and flowering type, putting agricultural production and sustainable development at risk. The objective of this study was to evaluate the climatic effect, water management, and flowering type on fruit nutrient content in six orchards in the state of Michoacan. Six orchards were evaluated in the towns of Basilia, Cheranguerán, Tecario, Araparicuaro, Peribán and Patamburu in the state of Michoacan, which represent 90% of the climate types (TC), predominant in the state (ACW1, ACW2 and CW1)., with 100% of the water regime (irrigated and seasonal, RH) and 97% of the type of fruit produced (loca and normal, FF). The dry matter contents and total mineral content of the fruit were evaluated. The arrangement of treatments was a factorial [A= water regime (RH); B= type of climate (TC); C= floral flow (FF)], distributed completely randomly with 20 repetitions taking each tree as a repetition. The results indicated that the dry matter content is affected by TC, but not by RH and FF, FF affects the nutritional content more than TC and RH. The type of climate is the factor with the least impact on the mineral content of the fruit. In floral flow, the total nutritional content was significant in four elements with higher values for N, Cl, and Zn in crazy fruit and Na in normal fruit.

Resumen: El aguacate (Persea americana), es un fruto que ha incrementado su consumo a nivel mundial. México es el principal productor y exportador de aguacate en el mundo que representa más del 30% de la cosecha mundial, del cual el 73.2% de la producción total de aguacate en México se concentra en el estado de Michoacán, pero dicha producción es afectada por la variación del clima, poniendo en peligro la producción agrícola y el desarrollo sostenible. El objetivo del fue evaluar el efecto climático, manejo de agua y el tipo de floración sobre el contenido nutrimental del fruto en seis huertas del estado de Michoacán. Se evaluaron seis huertos de las localidades de la Basilia, Cheranguerán, Tecario, Araparicuaro, Peribán y Patamburu del estado de Michoacan, que representan un 90% de los tipos de clima (TC), predominantes en el estado (ACW1, ACW2 y CW2), con un 100% del régimen de agua (riego y temporal, RH) y un 97% del tipo de fruto producido (loca y normal, FF). Se evaluaron los contenidos de materia seca y el contenido mineral total del fruto. El arreglo de tratamientos fue una factorial [A= régimen hídrico (RH); B= tipo de clima (TC); C= flujo floral (FF)], distribuido completamente al azar con 20 repeticiones tomando cada árbol como una repetición. Los resultados indicaron que el contenido de materia seca es afectado por TC, pero no por RH y FF, FF afecta más el contenido nutricional que TC y RH. El tipo de clima es el factor de menor impacto en el contenido mineral del fruto. En flujo floral el contenido nutricional total fue significativo en cuatro elementos con mayor valor para N, Cl, y Zn en fruto loca y Na en fruto normal.

Resumo: Introdução: A hipertensão arterial (HA) é a principal causa de morte por doenças cardiovasculares. Apesar dos avanços, o percentual de hipertensos não diagnosticados e não tratados é de 58,4%. A avaliação do dano cognitivo na hipertensão concentra-se na prevenção do acidente vascular cerebral, enquanto o dano funcional é ignorado. Esse manejo inadequado pode ser multifatorial. É objetivo fue analisar a opinião dos médicos sobre a relação entre hipertensão arterial e danos cognitivos. Metodologia: Estudo observacional, descritivo, transversal desenvolvido no período entre agosto de 2020 e agosto de 2023. Análise de dados obtidos a partir de questionário autoaplicável, anônimo e voluntário. Revelar informações sobre o perfil profissional, conhecimento sobre a HA, sua ligação com o comprometimento cognitivo (DC), diagnóstico e tratamento. Resultados: Foram incluídos 222 profissionais, 215 (96,8%) concordam com a existência de ligação entre hipertensão e outros fatores de risco cardiovascular na DC e 218 (98,1%) reconhecem ajudar pacientes com risco de sofrer de D.C. A avaliação da DC é realizada em casos selecionados por 132 (59,4%) participantes e 59 (26,7%) a fazem sempre. Dos que realizam avaliação, 103 (54%) utilizam o Mini Exame do Estado Mental (MEEM), 10 (5,2%) utilizam a Avaliação Cognitiva de Montreal (MoCA) e 9 (4,7%) utilizam o Clock Drawing Test. Em relação à diminuição da pressão arterial em pacientes idosos e a ligação com o risco de DC: 54 (24,3%) não reconhecem risco e 65 (29,2%) reconhecem risco moderado-alto. Em referência à implicação do tratamento de doenças cardiovasculares e DC: 217 (97,7%) reconheceram o efeito benéfico. Discussão: Dado o reconhecimento da ligação entre hipertensão e DC, seria de esperar que a DC fosse investigada na grande maioria, no entanto apenas 26,7% sempre a avaliam. Não há consenso sobre o método, sendo o MEEM o mais utilizado, com baixa aplicação do teste MoCA e/ou Clock Drawing Test, sendo estes últimos os que avaliam a função executiva, majoritariamente alterada nos DC vinculados à HA. Embora o tratamento das doenças cardiovasculares seja reconhecido como benéfico em relação à DC, o controle da HA em idosos é considerado arriscado. É feito um diagnóstico de uma situação em que é evidente uma disparidade entre o que se reconhece como saber e o que se afirma fazer. Conclusões: O papel da doença vascular no dano cerebral funcional é reconhecido, considerando-se necessário conhecer o estado cognitivo dos pacientes, porém há baixa aplicação de testes de triagem que avaliam a função executiva. Nesse contexto, evidencia-se uma lacuna entre o conhecimento e a prática médica.

Abstract: Introduction: High blood pressure (HBP) is the leading cause of death from cardiovascular disease. Despite the advances, the percentage of undiagnosed and untreated hypertensive patients is 58.4%. The evaluation of cognitive damage in HBP focuses on preventing stroke, while functional damage is ignored. This inadequate management may be multifactorial. The objective was to analyze the opinions that doctors have about the relationship between high blood pressure and cognitive damage. Methodology: Observational, descriptive, cross-sectional study developed in the period between August 2020 and August 2023. Analysis of data obtained from a self-administered, anonymous and voluntary questionnaire. Revealing information on the professional profile, knowledge of HBP, its link with cognitive impairment (CD), diagnosis and treatment. Results: 222 professionals were included, 215 (96.8%) agree with the existence of a link between HBP and other cardiovascular risk factors in CD, and 218 (98.1%) acknowledge assisting patients at risk of suffering from CD. The CD evaluation is carried out in selected cases by 132 (59.4%) participants and 59 (26.7%) always do it. Of those who perform evaluation, 103 (54%) use the Mini Mental State Examination (MMSE), 10 (5.2%) use the Montreal Cognitive Assessment (MoCA) and 9 (4.7%) use the Clock Drawing Test. Regarding the decrease in blood pressure in elderly patients and the link with risk of CD: 54 (24.3%) do not recognize risk and 65 (29.2%) recognize a moderate-high risk. In reference to the implication of the treatment of cardiovascular disease and CD: 217 (97.7%) recognized a beneficial effect. Discussion: Given the recognition of the link between HBP and CD, it would be expected that CD would be investigated in the vast majority, however only 26.7% always evaluate it. There is no consensus on the method, the MMSE being the most used, with a low application of the MoCA test and/or Clock Drawing Test, the latter being the ones that evaluate executive function, mostly altered in CD linked to HBP. Although the treatment of cardiovascular disease is recognized as beneficial with respect to CD, the control of HBP in older adults is considered risky. A diagnosis is made of a situation where a disparity is evident between what one recognizes as knowing and what one claims to do. Conclusions: The role of vascular disease in functional brain damage is recognized, considering it necessary to know the cognitive status of patients, however there is a low application of screening tests that evaluate executive function. In this context, a gap between medical knowledge and practice is shown.
