Introducción: la colonoscopia es un procedimiento quirúrgico de alto valor diagnóstico, pronóstico y terapéutico, en cuya ejecución se emplea analgesia quirúrgica acupuntural como uno de los métodos evaluados.Objetivo: evaluar la efectividad de la analgesia quirúrgica acupuntural en pacientes atendidos en el servicio de gastroenterología.Métodos: se realizó un estudio experimental con asignación aleatoria de pacientes a dos grupos en proporción 1:1. La población del grupo I estuvo constituida por 100 pacientes, con indicación de colonoscopia, atendidos en el servicio de gastroenterología del Hospital General “Dr. Juan Bruno Zayas Alfonso”, de Santiago de Cuba, en el período de mayo de 2017 a marzo de 2019, que cumplieron con los criterios de la investigación. El grupo I recibió tratamiento con analgesia quirúrgica acupuntural y el grupo II recibió tratamiento convencional medicamentoso. Se estudiaron las variables edad, sexo, dolor, tiempo de recuperación, efectos adversos, y efectividad general de la técnica.Resultados: en el peroperatorio 96,00 % de los pacientes del grupo I no presentaron dolor, mientras que en el posoperatorio esta proporción alcanzó 100,00 %, no así en el grupo II. Todos los pacientes tratados con analgesia quirúrgica acupuntural se recuperaron rápidamente; solo dos (4,00 %) presentaron efectos adversos.Conclusiones: los efectos de la analgesia quirúrgica acupuntural en la realización de colonoscopias a pacientes con afecciones gastroenterológicas, son ligeramente superiores respecto a los de la medicamentosa en cuanto a la ausencia de dolor, menor tiempo de recuperación y poca frecuencia de presentación de efectos adversos.

Introduction. Within artificial intelligence, the use of artificial neural networks is becoming increasingly important. Objective. Estimate the error of the Biochemical Oxygen Demand in wastewater from laundries of jeans of the city of Pelileo using neural networks. Methods. First, a database consisting of six physical parameters, nine chemical parameters and an output variable was developed. These variables were selected using the TUSLA Standard and were compiled from the cadastre of the GAD Pelileo of the years 2017-2018 and a certified water analysis laboratory. Next, the Matlab software was used with the design of the Artificial Neural Network FeedForward Backpropagation with the input layer of fifteen variables. The first hidden layer had ten neurons, the second summatory layer with one neuron and the output layer with the response variable corresponding to the estimation of the Biochemical Oxygen Demand with the Levenberg-Marquardt learning algorithm. Results. Values of the correlation coefficient, the estimated network error, and the comparison of the Tukey Test were obtained, susch as: 0.98081; 0.8890; 0.9833. These figures reveal a concordance between the values estimated by the network and the actual values. Finally, the results showed that Biochemical Oxygen Demand was estimated numerically in wastewater through neural models. This type of model of neurons represents only part of the mathematical function that the network builds from the set of observations.

Introduction. Post-surgical infections are currently a topic on the rise due to different causes such as resistance to common drugs, failures in asepsis or problems in the post-surgical recovery of the patient. In turn, the use of systemic antibiotics is a controversial issue where their exclusive use predominates in really necessary cases, and if possible avoid their use. The alternatives for the control of post-surgical infections are few and often difficult to apply depending on the case. . Goal. Evaluate the use and efficacy of 0.1% polyhexanide (Prontosan Gel ® - T1) being a chemical product for human use with antiseptic, moisturizing, antibacterial and healing properties; in contrast to the use of a natural product for veterinary use such as 100% Manuka (Kruuse Manuka G ® – T2). Methodology. This study was observational and comparative with an experimental design assigning each drug a treatment group with 15 female felines (Felis silvestris catus) undergoing the OVH surgical procedure (Ovarian hysterectomy) at the "VET911" veterinary clinic in the city of Guayaquil and documenting their progress with each treatment for 21 days. Results. Under this study it was shown that in patients treated with Prontosan was a greater control of the bacterial load present in the incision, a shorter healing time than the T2 group and a remarkable stability in terms of inflammation, itching and pain on palpation by part of the T1 group. Conclusion. The polyhexadine for human use showed superior healing capacities than the drug for veterinary use when favoring the regeneration and healing of post-surgical wounds, a fact that is scientifically extraordinary.

Objetivo. Diagnosticar la incidencia de enfermedades renales, mediante biomarcador SDMA. en pacientes caninos geriátricos, mayores de 8 años. Introducción. La enfermedad renal crónica (ERC) es una enfermedad que aqueja a pacientes caninos, por lo general, geriátricos; ésta afecta a la funcionalidad de los riñones y se presenta como una de las enfermedades comunes en animales. El diagnóstico de ERC se suele realizar cuando las funciones renales se encuentran disminuidas en al menos 25% y presenta sintomatología clínica. Metodología. El presente trabajo de investigación se centró en diagnosticar ERC a través del biomarcador SDMA, mediante el análisis de 52 pacientes seleccionados al azar (n=52) entre 8 a 10 años de edad (AdE), sin distinción de sexo o raza, sin síntomas relacionados con la ERC al momento de la consulta, y los cuales fueron atendidos en la Clínica Veterinaria Beethoven de la ciudad de Santo Domingo de los Tsáchilas en Ecuador. Se realizó un análisis estadístico a través de una prueba de correlación de Pearson sobre la concentración de SDMA, urea y creatinina. Resultados. Se determinó que el 34,6% de los pacientes poseen una concentración del biomarcador SDMA mayor a 20 ug/dL, predominando en pacientes de 8 AdE (19,2%), de los cuales el (25%) fueron hembras y pacientes con un peso de más de 9 kg (19,2%). El presente estudio determinó que no se presenta una relación entre los biomarcadores en pacientes sin síntomas de ERC; sin embargo, esto no descarta el desarrollo de ERC con pacientes que presenten al menos el 25% de riñones afectados.

The objective of the research is to determine what are the factors that affect the aging of older adults in Ambato, to achieve this objective the descriptive-analytical method was used because it allowed to identify those factors that are diverse depending on the needs and deficiencies that have people who have reached this stage of their lives, since the reality of a retiree who has his monthly economic pension is not the same as those who do not have it, and even more so to those who experience the uprooting of their family, without leaving to mention that to a precarious life situation of the elderly, serious health problems and disabilities are generally added, which demand significant resources that are not able to solve, for this reason the co-responsibility that must exist between the State agencies, be they these national or local, must be associated with the care of the family nucleus closest to the older adult, an important finding part of this research explains the factors that affect a dignified aging that include medical and psychological care, safe access for mobility without danger, economic income necessary to cover their basic needs and family support for those who have this possibility.

Digital tools today have been gaining strength in the activities carried out by teachers in their classes, however there are many teachers who still do not have full knowledge of the proper use for certain specific areas of teaching, for this reason the research is tries to Analyze and Provide teachers with interactive digital tools that allow improving reading comprehension, to obtain the number of teachers who do not know and have not used a research methodology that allows collecting data from a small population of teachers. with a quantitative and non-experimental method and also with an instrument in this case a questionnaire elaborated with the Likert scale through which I help to obtain the necessary data in order to determine the proposal, in this case the information that was tabulated through a frequency table was obtained that 83.3 of the total population They have almost never applied tools such as Quizizz, Genially to assess students, and that 94.4% of the total population has almost never used digital tools for reading comprehension. Given these statistical data, a proposal was presented to the teacher that consists of some digital tools that he can use in his classes, among which are: Genially, Quizizz, newsela, nearpod and padlet and in this way the objectives set from the beginning of the course are met. the investigation.

In the last decade, entrepreneurship has established itself as an opportunity for human development and a fundamental contribution to the economic growth of nations. The objective of this study was to identify the sustainability factors that intervene in the development of microenterprises, taking the Octavio Cordero Palacios parish in the city of Cuenca as a case study. A quantitative study was conducted with a descriptive-cross-sectional approach, whose data were collected in a non-probabilistic sample of sixty-one micro-enterprises, applying an Adhoc survey based on the contributions of previous studies. The results indicate that most enterprises are run by women of approximately 49 years of age, with basic academic training, whose businesses operate at home, have their own capital, do not receive financial support from the State or private banks and they are in a mature stage (5 years). Based on these results, strategies are established that can contribute to the sustainability of small businesses that arise in rural sectors.
