    Asociación Entre la Fuerza Prensil con las Comorbilidades Macrovasculares en Población con Diabetes Mellitus Tipo 2 Perteneciente a la Cohorte PURE Colombia
    (2021-12-06) Calderón-Méndez, Kevin Joshua; Capodicasa-Peñuela, Carmelo Jesús; Paez-Fernandez, Sofía; Sanchez-Camacho, Juan Sebastian; Montaño-Villalba, Ludivia Esther; Otero, Johanna
    La diabetes mellitus tipo 2 es una enfermedad crónica que se caracteriza porque la insulina no está siendo utilizada de forma correcta. Esta patología puede desarrollar comorbilidades macrovasculares, las cuales están asociadas con la disminución en la fuerza prensil. El objetivo de este estudio fue determinar la asociación entre la fuerza prensil con comorbilidades macrovasculares en población con diabetes mellitus tipo 2 perteneciente a la cohorte PURE de la línea de base conformada en el periodo 2005-2009. Metodología: Estudio transversal, analítico y retrospectivo, en el cual se tuvo una población de 430 sujetos con diabetes mellitus tipo 2. Se utilizaron las pruebas de chi-cuadrado para variables discretas y t-student para variables continuas. Se construyeron modelos de regresión para determinar la asociación entre las variables independientes y comorbilidades macrovasculares mediante la estimación de OR y sus respectivos intervalos de confianza. Resultados: Al caracterizar la población, la edad promedio fue de 55.9 años, encontrando una mayor presencia del sexo femenino con un 67.7%. En relación con los modelos de regresión se observó que las personas que se encuentran en el tercil 3 que corresponde al grupo con mayor fuerza prensil, tienen menor probabilidad de presentar comorbilidades macrovasculares en comparación con las que se encuentran en el tercil 1 las cuales presentan menor fuerza prensil. Conclusiones: Se determinó la asociación entre la fuerza prensil con la presencia de comorbilidades macrovasculares en personas diabéticas, en la cual se encontró que las personas que están ubicadas en el tercil 3 de fuerza prensil tienen menor probabilidad de presentar comorbilidades macrovasculares.

    Blood glucose response to two intensities of physical exercise in young women during fasting
    (2018-02-26) Sánchez Delgado, Juan Carlos; Angarita Fonseca, Adriana; Aguirre Aguirre, Clara Liliana; Aguirre Rueda, Diana M.; Pulgarín Araque, Rubén D.; Pinzón Romero, Sandra
    Introduction: Physical exercise in the fasting state has been a controversial topic; however, some studies have shown a greater loss of body fat and better glycemic control in those who participate in aerobic training when fasting. Aim: To evaluate the glycemic response after a session of moderate or vigorous physical exercise in young women in the state of fasting. Material and method: A randomized clinical trial was carried out. Twenty-six women (19 to 22 years old) were randomly assigned to two intervention groups. The first group was trained at an intensity of 70% of maximum heart rate (MHR) for 30 minutes, and the second group at an intensity of 90% MHR for 15 minutes. Height (cm), weight (Kg), body mass index (BMI), fat percentage, and maximum oxygen consumption (VO2max) during a stress test were evaluated. Blood glucose levels were checked before and after the exercise session of each group. Results: No significant changes were found in post-exercise blood glucose levels in any experimental group, and the existing differences were not statistically significant. Conclusions: Moderate or vigorous physical exercise during fasting did not show significant variations in blood glucose, which suggests that it is safe for healthy young women to train when fasting.

    Effect of a Very-Low-Calorie Ketogenic Diet on Circulating Myokine Levels Compared with the Effect of Bariatric Surgery or a Low-Calorie Diet in Patients with Obesity
    (2019-10-04) Sajoux, Ignacio; Lorenzo, Paula M.; Gomez-Arbelaez, Diego; Zulet, M. Angeles; Abete, Itziar; Castro, Ana I.; Baltar, Javier; Portillo, María P.; Tinahones, Francisco J.; Martinez, J. Alfredo; Crujeiras, Ana B.; Casanueva, Felipe F.; Masira
    The preservation of muscle mass and muscle function after weight loss therapy is currently a considerable challenge in the fight against obesity. Muscle mass secretes proteins called myokines that have relevant functions in the regulation of metabolism and health. This study was aimed to evaluate whether a very low-calorie ketogenic (VLCK) diet may modulate myokine levels, in addition to changes in body composition, compared to a standard, balanced low-calorie (LC) diet or bariatric surgery in patients with obesity. Body composition, ketosis, insulin sensitivity and myokines were evaluated in 79 patients with overweight/obesity after a therapy to lose weight with a VLCK diet, a LC diet or bariatric surgery. The follow-up was 6 months. The weight loss therapies induced changes in myokine levels in association with changes in body composition and biochemical parameters. The effects on circulating myokine levels compared to those at baseline were stronger after the VLCK diet than LC diet or bariatric surgery. Differences reached statistical significance for IL-8, MMP2 and irisin. In conclusion, nutritional interventions or bariatric surgery to lose weight induces changes in circulating myokine levels, being this effect potentially most notable after following a VLCK diet.
