Unchanged Hypovitaminosis D and Secondary Hyperparathyroidism in Morbid Obesity after Bariatric Surgery
Juan Ybarra,Joan Sánchez-Hernández,Ignasi Gich,Alberto de Leiva,Xavier Rius,J Rodríguez-Espinosa,Antonio Pérez +6 more
TL;DR: It seems advisable to support vitamin D supplementation in the morbidly obese population and Hypovitaminosis D with secondary hyperparathyroidism due to low calcidiol bio-availability should be added to the crowded list of sequelae of morbid obesity.
Journal ArticleDOI
PTEN promoter methylation in sporadic thyroid carcinomas.
Francisco Alvarez-Nuñez,Elena Bussaglia,Didac Mauricio,Juan Ybarra,Monica Vilar,Enrique Lerma,Alberto de Leiva,Xavier Matias-Guiu +7 more
TL;DR: A high frequency of PTEN promoter hypermethylation is shown, especially in follicular tumors, suggesting its possible role in thyroid tumorigenesis.
Journal ArticleDOI
Stem cells isolated from adipose tissue of obese patients show changes in their transcriptomic profile that indicate loss in stemcellness and increased commitment to an adipocyte-like phenotype
Blanca Oñate,Gemma Vilahur,Sandra Camino-López,A. Díez-Caballero,Carlos Ballesta-López,Juan Ybarra,Fabrizio Moscatiello,Javier Herrero,Lina Badimon +8 more
TL;DR: The transcriptomic profile of the stem cells reservoir in obese subcutaneous WAT is highly modified with significant changes in genes regulating stemcellness, lineage commitment and inflammation.
Journal ArticleDOI
The subcutaneous adipose tissue reservoir of functionally active stem cells is reduced in obese patients
Blanca Oñate,Gemma Vilahur,Raquel Ferrer-Lorente,Juan Ybarra,A. Díez-Caballero,Carlos Ballesta-López,Fabrizio Moscatiello,Javier Herrero,Lina Badimon +8 more
TL;DR: It is reported that subcutaneous WAT stromal vascular fraction from nonobese individuals had a significantly higher number of CD90+ cells than SVF from obese patients, and ADSCs in adipose tissue of obese patients have lower capacity for spontaneous or therapeutic repair.
Journal ArticleDOI
A new table for prevention of hypoglycaemia during physical activity in type 1 diabetic patients
TL;DR: It is shown that by replacing adequately the carbohydrates during the practice of physical exercise it is possible to prevent almost all hypoglycaemia episodes, independently of the insulin dosage adjustments.
