Se presenta una metodología a seguir para el análisis de un asiento trasero durante la prueba de anclaje del cinturón de seguridad, establecida en la norma FMVSS 210 por sus siglas en ingles Federal Motor Vehicle Safety Standards. Es importante destacar que el cinturón de seguridad reduce el riesgo de lesiones, y en caso de colisión, el cinturón ayuda a distribuir la fuerza del impacto en una superficie más grande es decir la estructura metálica del asiento, lo que se busca es minimizar el riesgo de lesiones graves. La metodología propuesta tiene el fin de predecir el desempeño como función del desplazamiento de la estructura metálica mediante el uso del elemento finito (FEM). En esta metodología, se analiza la menor cantidad de elementos que compone la estructura del asiento con el propósito de reducir el tiempo del análisis, considerando solo los elementos y componentes que tienen mayor efecto con el desempeño del cinturón de seguridad, generando el análisis más rápido y eficiente. Al contrastar los resultados obtenidos a través del análisis mediante elemento finito con las pruebas reales se determinó que el método FEM es eficaz para predecir los puntos débiles de la estructura metálica que influyen en el desplazamiento y/o deformación del asiento durante la prueba.

A methodology is presented for analysis of a rear seat during the Safety Belt Anchorage test established in FMVSS 210 [1], which stands for Federal Motor Vehicle Safety Standards. It is important to note that the safety belt reduces the risk of injury, and in the event of a collision, the belt helps distribute the force of the impact over a larger surface area, namely the metal structure of the seat. The goal is to minimize the risk of serious injuries. The goal of proposed methodology is to predict the performance as a function of displacement of the metal structure by using Finite Element Method (FEM). In this methodology, the minimum number of elements that make up the seat structure is analyzed in order to reduce analysis time, considering only the elements that play and have effect on the performance of the safety belt, thus generating a faster and more efficient analysis. By comparing the results obtained through Finite Element Method with the actual test, it was determined that the FEM method is effective in predicting the weak points of the metal structure that influence the displacement and/or deformation of the seat during the test.

Metabolic syndrome (MS) has been associated with testicular damage. Nonalcoholic fatty liver disease (NAFLD) is a multisystemic disease that affects different organs, but its effect on the testes is unknown. A study analyzing germ cell involvement on BALB/c mice was carried out. A parallel comparative study was conducted that investigated alterations in the germinal epithelium of male humans that died from an unrelated acute event. The complete medical histories and histologic samples of the thoracic aorta, liver tissue, and testicular tissue from the deceased subjects were collected. The degree of germinal epithelial loss (DGEL) was evaluated and the clinical and histologic data were compared between individuals with and without NAFLD. The only metabolic or morphologic variable that caused a significant difference in the DGEL, in both the animal model and humans, was the presence of liver steatosis. The percentage of steatosis was also correlated with the percentage of the DGEL. In humans, steatosis (greater than 20%) increased the risk 12-fold for presenting with a severe DGEL (OR: 12.5; 95% CI [1.2, 128.9]; p = .03). There was no association with age above 50 years or MS components. Steatosis grade was also correlated with atherosclerosis grade. NAFLD was a strongly associated factor implicated in severe DGEL, as well as the testis was identified as a probable target organ for damage caused by the disease. his finding could result in the search for new approach strategies in the management of men with fertility problems. Further studies are required to confirm these results.

Sustainable urban mobility: An alternative for air pollution in the Guadalajara Metropolitan Area

José Antonio Olivares Mendoza Clemente Hernandez-Rodriguez Luz Alicia Jimenez Portugal (2023, [Artículo, Artículo])

The objective of this paper is to evaluate whether the low-carbon transport strategy (subway, rapid transit bus system -Macrobús-, trolleybus, and shared bicycles) implemented in the Guadalajara Metropolitan Area (AMG) from 2000 to 2019 improves air quality. Sustainable urban mobility is the movement of people in cities in a way that generates the least impact on the environment. We analyze three actions of government intervention in the same sense. This is the first study for Guadalajara, the third-largest city in Mexico. We use robust Newey-West estimators and endogenously model pollution disruptions using the Bai Perron approach. Our results suggest that this type of public transport reduces SO2, NO2, O3, and CO, though we find an increase in PM10. We also identified that when the service of the first line of the Bus Rapid Transit was consolidated CO, O3 and PM10 decreased. In addition, the improvement in the connectivity of the bus network with the subway means that only NO2 diminished. Finally, the entry into operation of the shared bicycle program reduced PM10, while increasing O3 and in SO2. In short, sustainable urban mobility is an alternative to making the transit of people efficient, while mitigating air pollution in the AMG.

Propuesta de mejora para la integración del equipo de salud en el código azul en áreas críticas adulto

DANIEL GARCIA NAVARRETE (2023, [Otro, Trabajo terminal, especialidad])

La presente investigación se realizará en un hospital de segundo nivel de atención de la ciudad de Cuernavaca, el código azul es un sistema de alarma que existe en la mayoría de los hospitales, está conformado por un equipo multidisciplinario de salud que se encuentra capacitado y es convocado de manera inmediata con funciones previamente asignadas para poder intervenir de forma oportuna, eficaz y con calidad a pacientes en paro cardiopulmonar. Este trabajo de investigación propone la integración del equipo de salud en código azul.

Se menciona como fue la historia de la formación de los grupos de reanimación cardiopulmonar y la organización del código azul; fue el primer modelo de estos sistemas y ha demostrado un impacto positivo en la morbimortalidad de los pacientes, la conexión de la teórica Patricia Benner de principiante a experto, se describe como se vive un código azul en el área hospitalaria, la necesidad de estructurar tarjetas que identifique que rol tiene cada uno de los integrantes del código azul, el personal de salud tiene que tener capacidad de reconocer la emergencia del evento, realizando oportunamente las intervenciones del código azul. Metodología adecuada para esta investigación: se decidió un estudio de tipo cuantitativo, longitudinal, observacional, cuasiexperimental y de intervención educativa, será dirigido a todo profesional de salud; área médica, enfermería, camilleros, residentes, pasantes y estudiantes de ambas profesiones de los diferentes turnos que laboran en las áreas críticas del hospital. Se pretende aplicar dos instrumentos de evaluación diagnóstica y de habilidades previo a la capacitación curso- taller con la finalidad de fortalecer los conocimientos y habilidades y posteriormente aplicar los mismos instrumentos de evaluación final. Se implementará un pizarrón en cada servicio, donde describa el rol de la actividad que tendrá cada integrante que conforme el equipo de código azul, así mismo se proporcionará el manual de procedimientos de código azul, guía de práctica clínica impresa que se ubicaran en un lugar estratégico para su consulta y gafetes que describa la función que le corresponde a cada uno de los miembros.

This research will be carried out in a second level care hospital in the city of Cuernavaca. The code blue is an alarm system that exists in most hospitals; it is made up of a multidisciplinary health team that is trained and immediately summoned with previously assigned functions in order to intervene in a timely, effective and quality manner in patients in cardiopulmonary arrest. This research work proposes the integration of the health team in code blue.

It mentions the history of the formation of cardiopulmonary resuscitation groups and the organization of the code blue; it was the first model of these systems and has shown a positive impact on patient morbidity and mortality, the connection of the theorist Patricia Benner from beginner to expert, it describes how a code blue is experienced in the hospital area, the need to structure cards that identify the role of each of the members of the code blue, the health personnel must have the ability to recognize the emergency event, performing timely interventions of the code blue. Appropriate methodology for this research: a quantitative, longitudinal, observational, quasi-experimental, quasi-experimental and educational intervention study was decided, and it will be directed to all health professionals; medical area, nursing, orderlies, residents, interns and students of both professions of the different shifts that work in the critical areas of the hospital. It is intended to apply two diagnostic and skills evaluation instruments prior to the training course-workshop in order to strengthen knowledge and skills and then apply the same instruments for the final evaluation. A blackboard will be implemented in each service, describing the role of the activity that each member of the code blue team will have, as well as the code blue procedure manual, printed clinical practice guide that will be placed in a strategic place for consultation and badges that describe the function that corresponds to each of the members.
