Citric Acid Cycle Metabolites Predict Infarct Size in Pigs Submitted to Transient Coronary Artery Occlusion and Treated with Succinate Dehydrogenase Inhibitors or Remote Ischemic Perconditioning.

Succinate dehydrogenase (SDH) inhibition with malonate during reperfusion reduced myocardial infarction in animals, whereas its endogenous substrate, succinate, is detected in plasma from STEMI patients. We investigated whether protection by SDH inhibition is additive to that of remote ischemic perconditioning (RIC) in pigs submitted to transient coronary artery occlusion, and whether protective maneuvers influence plasma levels of citric acid cycle metabolites. Forty pigs were submitted to 40 min coronary occlusion and reperfusion, and allocated to four groups (controls, sodium malonate 10 mmol/L, RIC, and malonate + RIC). Plasma was obtained from femoral and great cardiac veins and analyzed by LC-MS/MS. Malonate, RIC, and malonate + RIC reduced infarct size (24.67 ± 5.98, 25.29 ± 3.92 and 29.83 ± 4.62% vs. 46.47 ± 4.49% in controls, p < 0.05), but no additive effects were detected. Enhanced concentrations of succinate, fumarate, malate and citrate were observed in controls during initial reperfusion in the great cardiac vein, and most were reduced by cardioprotective maneuvers. Concentrations of succinate, fumarate, and malate significantly correlated with infarct size. In conclusion, despite the combination of SDH inhibition during reperfusion and RIC did not result in additive protection, plasma concentrations of selected citric acid cycle metabolites are attenuated by protective maneuvers, correlate with irreversible injury, and might become a prognosis tool in STEMI patients.

La musicoterapia como asignatura en los estudios de grado en enfermería / Music therapy as a subject in grade studies in nursing

Introducción: la musicoterapia se entiende por el uso de la música o sus elementos con fines terapéuticos. Su empleo en la enfermería es escaso más allá del uso de la intervención NIC 4400. Objetivo: conocer y analizar el grado de aceptación por parte de los estudiantes de enfermería ante la posible inclusión de la musicoterapia como asignatura en los programas educativos de los estudios de Grado en Enfermería. Método: se ha realizado un estudio observacional descriptivo de corte transversal con una muestra n=346 participantes. Resultados: los resultados muestran que el 93,93% de los alumnos sí incluirían la musicoterapia como una asignatura Optativa en los estudios de Grado en Enfermería, haciendo uso de ella en su futuro profesional

Introduction: music therapy is understood by the use of music or its elements for therapeutic purposes. Its use in nursing is scarce beyond the use of the NIC 4400 intervention. Objective: the research aims to know and analyze the degree of acceptance by nursing students regarding the possible inclusion of music therapy as a subject in the educational programs of the Nursing Degree studies. Method: a cross-sectional, observational, descriptive study was carried out with a sample of n=346 participants. Conclusion: the results show that 93.93% of the students did include music therapy as an optional subject in Nursing Degree studies, making use of it in their professional future
