Background and Aim: The therapeutic education and self-management carried out by nurses, are winning elements in cardiovascular secondary prevention, but because they are complex matters, they require special training by the professionals. The target of the study has been to assess the effects in clinical practice of a training program for nurses in the management of patients with cardiovascular diseases, leaning towards a self-oriented patient management and therapeutic patient education., Method: The research utilized a quali-quantitative study to compare the responses of 53 trained nurses (experimental group) and 101 untrained nurses (control group). The instrument used was a self-report structured in two sections: the first, a qualitative kind, was used to investigate the portrayal of nurses regarding self-management; the second, a quantitative kind, included a Likert scale based on 5 points (1=never, 5=always) that investigated the professional nurse's action in its bio-psycho-socio-relational and clinical activities (La Sala, 2012)., Results: The trained nurses' approach is more oriented towards the psycho-socio-relational dimension, compared to the untrained nurses. A difference also emerged regarding activities of a bio clinical nature, which are performed much more by untrained nurses compared to trained professionals., Conclusions: The health education and self-management skills were used by trained nurses during their care of patients with cardiovascular diseases, stressing the importance for professional nurses to develop an integrated competence, using narrative talks as the main tool in a patient-centred approach.

Purpose: The purpose of this study was to correlate portal hemodynamics on sonography and liver volume on MRI with histologic findings in asymptomatic patients with chronic hepatitis C., Methods: Portal blood flow in the left and right portal branches in 20 healthy volunteers and in 26 patients was measured using Doppler sonography during both fasting and postprandial states. Total liver and right-and left-lobe volumes were determined using MRI. The ratio between portal blood flow and liver volume determined the "portal flow index" of the right and left lobes., Results: We observed a statistically significant difference (p < 0.01) between the volunteers and patients in the mean left-lobe volume (352 +/- 81 cm(3) versus 544 +/- 159 cm(3)) and in the mean left portal flow index (1.1 +/- 0.2 ml/minute/cm(3) versus 0.69 +/- 0.2 ml/minute/cm(3)) as measured before the subjects ate. After a meal, the portal blood-flow volume in the right lobe was similar in the 2 groups but in the left lobe was significantly lower in the patients (p = 0.0009). The left postprandial portal flow index was inversely correlated with the grade of liver fibrosis (r = 0.533)., Conclusions: The left-lobe volume (positive predictive value, 83%; negative predictive value, 72%) and left postprandial portal flow index (positive predictive value, 86%; negative predictive value, 88%) are sensitive indicators of chronic hepatitis. The left postprandial portal flow index may be a useful test for differentiating patients with minimal or no fibrosis from patients with mild to severe fibrosis., (Copyright 2000 John Wiley & Sons, Inc.)
