Audiencia y motivaciones para el consumo de los contenidos de las Radios Universitarias en México : El caso de Radio UNI 89.7 UANL

Tesis inédita de la Universidad Complutense de Madrid, Facultad de Ciencias de la Información, leída el 10-11-2022El objetivo general de esta investigación es determinar las motivaciones y hábitos de consumo de la comunidad universitaria de la Universidad Autónoma de Nuevo León (UANL) con respecto a la programación de la estación Radio UNI 89.7. Tuvo como objetivos específicos analizar las preferencias de contenidos radiofónicos, diagnosticar el acceso, uso y preferencias de la radio universitaria para el mejoramiento de la programación mediática de la UANL, determinar el perfil del radioescucha universitario y conocer los intereses de programación y contenido. Se trata de una investigación de enfoque cuantitativo y corte descriptivo, a través de la técnica de la encuesta. La población estuvo conformada por 638 estudiantes y 260 profesores pertenecientes a diversas facultades ubicadas en el Campus Mederos de la Universidad Autónoma de Nuevo León y como complemento se aplicó una entrevista a los directores de las estaciones de radio universitarias de la Zona Metropolitana de Monterrey, en donde se ubica Radio Uni: Frecuencia Tec y Radio Udem. El instrumento está compuesto por 22 preguntas o reactivos y fue validado por tres expertos. El trabajo de campo se realizó durante los años 2019 a 2021. Los hallazgos evidencian cómo la supuesta audiencia que debería tener la radio universitaria se ha desplazado hacia preferencias que consume a través de Internet 2.0 y que es apenas durante los traslados de su casa a la Universidad cuando -en ocasiones- sintonizan Radio Uni, ya que prefieren las estaciones con contenidos musicales y recreativos. Todo ello obliga a la reflexión acerca de la función social de la radio universitaria.The general objective of this research is to determine the motivations and consumption habits of the university community of the Universidad Autónoma de Nuevo León (UANL) about the programming of the UNI 89.7 Radio Station. Its specific objectives were to analyze the preferences of radio content diagnose the access, use and preferences of the university radio for the improvement of the media programming of UANL, determine the profile of the university radio listener, and to know the interests of programming and content. This is an investigation with a quantity approach and a descriptive cut, through the survey technique. The population was made up by 638 students and 260 professors who belong to different faculties located in Mederos Campus of the Universidad Autónoma de Nuevo León, and as a complement, the application of an interview to the directors of the university radio stations of the Metropolitan zone in Monterrey, were Radio UNI is located: Frecuencia Tec and Radio UDEM. The instrument integrates 22 questions and was validated by three experts. The field work was carried out between 2019 and 2021. The findings show how the supposed audience that the university radios should have has shifted towards consumption preferences consumed through Internet 2.0 and that it is only during the transportation between their houses and the university when -sometimes- they tune into Radio UNI, because they prefer musical and recreative stations. All this forces us to think about the social function of university radio.Fac. de Ciencias de la InformaciónTRUEunpu

Efecto del transporte en los indicadores de bienestar en bovinos productores de carne; un análisis

Objective: Review different factors related to cattle transport associated with welfare indicators. Approach: During transport, cattle is subject to stress triggers that include: i) increased handling, ii) mixing of animals from different sources and contact with strangers, iii) physical challenges such as ramps, slippery surfaces, load density, movement, noise and vibration of the vehicle; iv) contact with new and unfamiliar environments; v) food and water deprivation; vi) changes in the social structure, vii) changes in climatic conditions such as temperature, radiation and humidity, viii) inability to rest, among other aspects. This document reviews the effects of transport on the welfare indicators of cattle and the effects of temperature, load density, duration of travel, rest, water and food provision among others.Objetivo: Revisar distintos factores relacionados con el transporte de ganado bovino asociados a los indicadores de bienestar. Aproximación: Durante el transporte los bovinos son sometidos a factores desencadenantes de estrés que incluyen: i) incremento del manejo, ii) mezcla de animales de diferente procedencia y contacto con personal extraño, iii) desafíos físicos como rampas, superficies resbaladizas, densidad de carga, movimiento, ruido y vibración del vehículo; iv) contacto con ambientes nuevos y no familiares; v) privación de alimento y agua; vi) cambios en la estructura social, vii) cambios en las condiciones climáticas como temperatura, radiación y humedad, viii) imposibilidad de descanso, entre otros aspectos. En este documento se revisan los efectos del transporte en los indicadores de bienestar del ganado bovino y los efectos de la temperatura, la densidad de carga, duración del viaje, provisión de descanso, agua y alimento entre otros

Symptom cluster analysis of long COVID-19 in patients discharged from the Temporary COVID-19 Hospital in Mexico City.

INTRODUCTION: Several reports have emerged describing the long-term consequences of COVID-19 and its effects on multiple systems. METHODS: As further research is needed, we conducted a longitudinal observational study to report the prevalence and associated risk factors of the long-term health consequences of COVID-19 by symptom clusters in patients discharged from the Temporary COVID-19 Hospital (TCH) in Mexico City. Self-reported clinical symptom data were collected via telephone calls over 90 days post-discharge. Among 4670 patients, we identified 45 symptoms across eight symptom clusters (neurological; mood disorders; systemic; respiratory; musculoskeletal; ear, nose, and throat; dermatological; and gastrointestinal). RESULTS: We observed that the neurological, dermatological, and mood disorder symptom clusters persisted in >30% of patients at 90 days post-discharge. Although most symptoms decreased in frequency between day 30 and 90, alopecia and the dermatological symptom cluster significantly increased (p < 0.00001). Women were more prone than men to develop long-term symptoms, and invasive mechanical ventilation also increased the frequency of symptoms at 30 days post-discharge. CONCLUSION: Overall, we observed that symptoms often persisted regardless of disease severity. We hope these findings will help promote public health strategies that ensure equity in the access to solutions focused on the long-term consequences of COVID-19

High-flow nasal cannula therapy for hypoxemic respiratory failure in patients with COVID-19.

INTRODUCTION: High-flow nasal cannula (HFNC) therapy in patients with hypoxemic respiratory failure due to COVID-19 is poorly understood and remains controversial. METHODS: We evaluated a large cohort of patients with COVID-19-related hypoxemic respiratory failure at the temporary COVID-19 hospital in Mexico City. The primary outcome was the success rate of HFNC to prevent the progression to invasive mechanical ventilation (IMV). We also evaluated the risk factors associated with HFNC success or failure. RESULTS: HFNC use effectively prevented IMV in 71.4% of patients [270 of 378 patients; 95% confidence interval (CI) 66.6-75.8%]. Factors that were significantly different at admission included age, the presence of hypertension, and the Charlson comorbidity index. Predictors of therapy failure (adjusted hazard ratio, 95% CI) included the comorbidity-age-lymphocyte count-lactate dehydrogenase (CALL) score at admission (1.27, 1.09-1.47; p < 0.01), Rox index at 1 hour (0.82, 0.7-0.96; p = 0.02), and no prior steroid treatment (0.34, 95% CI 0.19-0.62; p < 0.0001). Patients with HFNC success rarely required admission to the intensive care unit and had shorter lengths of hospital stay [19/270 (7.0%) and 15.0 (interquartile range, 11-20) days, respectively] than those who required IMV [104/108 (96.3%) and 26.5 (20-36) days, respectively]. CONCLUSION: Treating patients with HFNC at admission led to improvement in respiratory parameters in many patients with COVID-19

Impact of preemptive hospitalization on health outcomes at the temporary COVID-19 hospital in Mexico City: a prospective observational study.

INTRODUCTION: In response to the evolution of the coronavirus disease 2019 (COVID-19) pandemic, the admission protocol for the temporary COVID-19 hospital in Mexico City has been updated to hospitalize patients preemptively with an oxygen saturation (SpO2) of >90%. METHODS: This prospective, observational, single-center study compared the progression and outcomes of patients who were preemptively hospitalized versus those who were hospitalized based on an SpO2 ⩽90%. We recorded patient demographics, clinical characteristics, COVID-19 symptoms, and oxygen requirement at admission. We calculated the risk of disease progression and the benefit of preemptive hospitalization, stratified by CALL Score: age, lymphocyte count, and lactate dehydrogenase (<8 and ⩾8) at admission. RESULTS: Preemptive hospitalization significantly reduced the requirement for oxygen therapy (odds ratio 0.45, 95% confidence interval 0.31-0.66), admission to the intensive care unit (ICU) (0.37, 0.23-0.60), requirement for invasive mechanical ventilation (IMV) (0.40, 0.25-0.64), and mortality (0.22, 0.10-0.50). Stratification by CALL score at admission showed that the benefit of preemptive hospitalization remained significant for patients requiring oxygen therapy (0.51, 0.31-0.83), admission to the ICU (0.48, 0.27-0.86), and IMV (0.51, 0.28-0.92). Mortality risk remained significantly reduced (0.19, 0.07-0.48). CONCLUSION: Preemptive hospitalization reduced the rate of disease progression and may be beneficial for improving COVID-19 patient outcomes
