Haemodynamic performance of aortic pericardial bioprostheses and bileaflet prostheses at rest and during exercise: implications for the surgical management of patients with small aortic roots.

OBJECTIVE To determine the haemodynamic behaviour, at rest and during exercise, of aortic valve pericardial bioprostheses and different sizes of bileaflet prosthesis. DESIGN Observational study. SETTING Tertiary medical centre. PATIENTS AND INTERVENTIONS 74 patients (33 women, 41 men; mean age 64 years) in whom 40 pericardial bioprostheses and 34 bileaflet prostheses sized 19, 21, or 23 mm had been implanted to replace aortic valves. MAIN OUTCOME MEASURES Doppler echocardiography at rest and at peak exercise, between 12 and 47 months after surgery. RESULTS All patients achieved a significant increase in heart rate, systolic blood pressure, and cardiac output with exercise. Transvalvar pressure fall, valve area, and left ventricular systolic and diastolic function indices also underwent significant changes with exercise. Reductions in peak and mean transvalvar pressure, at rest and at peak exercise, were greater in patients with small valves (p < 0.05). Valve areas and effective area index were greater in the patients with larger valves (p < 0.001). There were no significant differences between patients with mechanical and biological prostheses with regard to transvalvar pressure fall and valve areas at rest and at peak exercise. CONCLUSIONS 19 mm and 21 mm aortic prostheses and bioprostheses continue to create significant obstruction, particularly with exercise.

Emotional Intelligence Profiles in College Students and Their Fathers’ and Mothers’ Parenting Practices

The present study has two objectives: first, to analyze whether the dimensions that make up emotional intelligence (attention, clarity, and repair) give rise to different profiles of university students, and secondly, to determine whether these different profiles are differentially associated with the parenting practices that students report with regard to their fathers and mothers. Results obtained indicate the existence of different profiles of college students. The profile that corresponds to adequate emotional skills presents a lower score in attention, but higher scores in clarity, and especially in mood repair. The other two profiles are inadequate, in the first case because a higher score in emotional attention is accompanied by low scores in mood repair, and in the second case because low scores are presented in all three dimensions. Likewise, we verified the existence of significant differences in the educational practices of parents, the adequate profile is characterized by greater use of parenting dimensions considered to be positive, and at the same time, lower scores on dimensions considered to be negative. One of the dysfunctional profiles is associated with higher scores in positive practices, and is also associated with higher scores in practices considered to produce a negative effect. The second dysfunctional profile is associated with higher scores on the dimensions considered to be negative and lower scores on positive dimensions.
