The mass production of tires, as well as the difficulty in reducing their waste, define a serious environmental problem. There are several methods for recycling discarded tires, one of the most common being mechanical shredding, in which the vulcanized rubber is separated from the steel and fibres, resulting in ground tire rubber (GTR). This rubber can be used in various applications such as insulating footwear soles, insulating floors, or as insulation for special electric motors. The objective of this research is to evaluate the use of this GTR when mixed with various types of polymeric matrix by measuring the mechanical, thermal, and dielectric properties of the resulting composites (polymer + GTR). The analysis was performed using four polymeric matrices (ABS, EVA, PA, and PP) mixed with different concentrations of GTR.

El desinterés en el aprendizaje de la lengua inglesa en las y los estudiantes de la Universidad Regional del Sureste (URSE) no es unproblema reciente, pero no se le ha dedicado la atención pertinente. El objetivo de esta investigación es identificar los factores que influyen en el desinterés estudiantil de estudiar la lengua inglesa. Para lograr identificar estos factores, se llevó a cabo una investigación mixta encuestando a 129 estudiantes universitarios cursando el cuartosemestre. Esto debido a que actualmente la mayoría de los programas educativos ofertados por la universidad cursan inglés hasta cuarto semestre. Después de aplicar las encuestas, los factores más influyentes en el aprendizaje del inglés fueron la dificultad de la lengua, seguida por la metodología de enseñanza empleada por las y los docentes y, finalmente, hay un problema de desmotivación en el estudiantado para aprender inglés. Esta investigación puede ser de gran apoyo al claustro docentepara buscar mejorías en los procesos de enseñanza-aprendizaje del inglés dentro de la universidad y lograr ofrecer clases de lenguaextranjera enfocadas a las necesidades del estudiantado.

Meckel's diverticulum is a congenital anomaly of the gastrointestinal tract that results from the persistence of the omphalomesenteric duct. Although most cases are asymptomatic, it can present with complications such as bleeding, intestinal obstruction, or inflammation. This report presents a clinical case of an incidental finding of a Meckel's diverticulum in a patient diagnosed with acute appendicitis. The patient, a young adult, underwent an appendectomy due to classical symptoms of acute appendicitis. During surgery, a Meckel's diverticulum unrelated to the appendicitis was identified. This finding is rare and underscores the importance of careful surgical evaluation and recognition of concurrent abnormalities in patients with acute abdominal conditions. Despite being an uncommon condition, this type of finding should be considered during the evaluation of surgical diagnoses, as it may have implications for surgical management and long-term prognosis. This report highlights the relevance of maintaining a high clinical suspicion and adequate surgical exploration in cases of acute abdomen.

Suicidal ideation is a process that is intertwined with suicidal behavior. It begins with the formation of an idea about whether it is worth continuing to live, an idea that can evolve and trigger a series of actions ranging from planning to the execution of the suicidal act. This is a descriptive observational study based on numerical measurements with its respective statistical analysis that established the behavioral patterns of the phenomenon studied. The research proposal was approved by the research committee of the Faculty of Medicine and Surgery, URSE; data collection was performed through the instruments: Beck Suicidal Ideation Scale, Beck Depression Inventory, Abbreviated Scale of School Bullying Questionnaire, Drug Dependence Identification Questionnaire, and Family Apgar. The prevalence of suicidal ideation was 5.4%; 19.7% of the medical students have been victims of bullying in any form; 22.2% reported regular use of alcohol, tobacco, drugs, and other addictive substances; in addition, 17.7% had mild family dysfunction, moderate in 9.9% and severe with 15.3%; depression was recorded to a mild degree with 6.4%, followed by moderate in 1.5% of cases. Suicidal ideation among medical students is of concern; these problems must be addressed comprehensively, promoting a supportive environment that promotes the mental health and well-being of medical students.

Opioid harm reduction and stigma: proposed methods to improve the perception of people with addiction. Front. Psychiatry : . doi: .

<strong>Introduction: </strong>In Mexico it affects approximately 2 million people, with a significant impact on quality of life and difficult to manage. <strong>Theoretical framework:</strong> The lesion it causes is round, salmon-pink papules and plaques, located on knees, elbows and scalp. The diagnosis is mainly clinical and the treatment will depend on the affected body surface and the location. The drugs considered first line are topical and second line drugs are used systemically, which in many occasions have adverse effects that make attachment difficult. Guselkumab, a drug approved in 2017, is an IgG1 that blocks the p19 subunit of IL-23. <strong>Discussion:</strong> Guselkumab, which is a monoclonal antibody, provides better patient outcomes compared to the drugs used in current therapeutics. There is little information currently available on Guselkumab since it has only recently been approved, but in all studies it has shown to be superior to other monoclonal antibodies, the main disadvantage being that it is not currently available in Mexico and the long administration time. <strong>Conclusion:</strong>Researching new drugs helps us to provide the patient with a treatment with the least amount of adverse effects, achieving greater adherence and better control of the disease.

Introducción: El aprendizaje autorregulado se identifica como un proceso activo, independiente, autónomo, crítico, adaptativo, reflexivo y estratégico, para lograr una formación integral, superación continua, autodeterminación, autonomía y actualización permanente.Objetivo: El objetivo de este trabajo fue el de analizar las estrategias de autorregulación de los estudiantes de pregrado durante la pandemia por COVID-19 adscritos a la Facultad de Medicina y Cirugía de la Universidad Regional Sureste para el ciclo lectivo 2020-A.Método: Se trata de un estudio descriptivo-transversal, la muestra se obtuvo mediante un muestreo aleatorio simple entre estudiantes de primero a quinto año, con sustitución de elementos de exclusión, el instrumento utilizado fue el cuestionario Torre adaptado (2007) y validado para este estudio.Resultados: Los sujetos de estudio demostraron una adecuada conciencia, control y verificación metacognitiva, además de tener un procesamiento activo durante las clases virtuales; sin embargo, presentan poco esfuerzo en la realización de las tareas, lo que nos lleva a establecer recomendaciones para la práctica educativa que refuerce sobre todo la enseñanza en el ámbito universitario de las ciencias de la salud.Conclusiones: El 70% de los estudiantes de pregrado de la Facultad de Medicina y Cirugía de la Universidad Regional del Sureste, se consideran autorreguladores en su proceso de aprendizaje durante este confinamiento derivado por la pandemia.

This paper shows a development practice for the requirements process of a medical application.In this process, a psychology specialist was included in order to improve the application from the specification of requirements, considering subjects such as: support networks, behavior modification, increased intrinsic and extrinsic motivation and the creation of tools to facilitate patientphysician communication.This resulted in 11 new requirements.When a psychology specialist is involved in the requirements process, a new perspective on the patient is obtained, one that is broader than the requirements engineer usually has.It considers human needs that can serve to stimulate the user to avoid certain negative behaviors or to encourage positive behaviors.One of the main objectives of an application that helps a patient in their medical treatment is that the user does not abandon it, and the psychological perspective created requirements may help in this.
