    ABSTRACT: INTRODUCTION: Venus cannulation is one of the main nursing actions. For the safety of patients and nurses, this skill is important to be performed in a proper and responsible way. Thus, the need for adequate education on this skill is essential. STUDY OBJECTIVE: Comparison between the 4-stage (demonstration, deconstruction, comprehension, performance) learning method and the simplified 2-stage method (deconstruction, performance) on venous cannulation. METHODS: The study took place from November 2011 to March 2012. In total, 117 students of the Nursing Department of Technological Educational Institute of Athens were randomized into two education groups of the 2- (Group A) and 4- (Group B) stage method respectively. Students of both groups were assessed during training and 45days later for skill retention. For the assessment of all students, a check list with the steps required to venous cannulation was used. The time to complete the process was also assessed. RESULTS: Group A included 54 students and Group B 50 students. During initial training, the average time to complete the process without any errors was lower for Group A compared to Group B (1.77±0.12min vs. 2.33±0.13min, p=0.006). Regarding the appropriate steps for venous cannulation, Group A made fewer errors compared to Group B (0.95±0.95 vs. 1.38±1.10, p=0.021). In addition, Group A omitted more steps than Group B (0.29±0.06 vs. 0.11±0.05, p=0.042). During skill retention assessment, no significant difference was observed in the number of incorrect steps or in the number of omitted steps between groups. CONCLUSION: According to our findings, the 4-stage method, is associated with less omitted steps, while the 2-stage method, is associated with less time required to complete the procedure and less errors during performance, at initial stages. However, skill retention does not seem to be associated with the type of the educational methodology.

    ABSTRACT: Background. The aim of the study was to investigate the changes in plasma lipids and lipoproteins and the cardiovascular events after selective LDL apheresis. Methods and Results. Two pediatric patients with familial hypercholesterolemia aged 11 and 13 years and 19 dyslipidemic adults aged 41 ± 14 years underwent direct adsorption of lipoproteins (DALI) sessions. The mean follow-up period was 47 ± 23 months. The total cholesterol (TC) values before and after treatment were 8.2 ± 2.2 and 3.1 ± 1.6 mmol/l (318 ± 86 and 122 ± 62 mg/dL), respectively. The interval mean of TC was 6.9 ± 1.9 mmol/l (268 ± 75 mg/dL). The LDL cholesterol concentrations before and after treatment were 6.6 ± 2.1 and 1.7 ± 1.1 mmol/l, (256 ± 82 mg/dL and 65 ± 41 mg/dL), respectively. The percentage of acute LDL cholesterol reduction was 75 ± 11%. Cardiovascular events were observed in seven patients. The average annual event rate was 5.51%. Conclusion. LDL apheresis is a very important therapeutic tool in managing patients at high risk for premature CAD or with aggressive CAD, despite adequate medical treatment.

    ABSTRACT: Transcatheter aortic valve implantation (TAVI) is a novel therapeutic option for severe aortic stenosis in old patients with high surgical risk. The aim of this study was to assess changes in quality of life (QoL) along with functional status and late survival after this procedure. Thirty-six consecutive patients (80.5 ± 5.9 years, 21 men and 15 women) with a logistic Euroscore of 29.7 ± 13.7 underwent TAVI using the 18-Fr CoreValve prosthesis. Aortic valve prosthesis was inserted retrograde using a femoral or a subclavian arterial approach. QoL was evaluated by administering the Short Form 36 (SF-36) tool and the shorter SF-12 version 2 (SF-12v2) questionnaires before and 1-year after TAVI. TAVI was successfully performed in all patients. The estimated 1-year overall survival rate using Kaplan-Meier method was 68%. One-year follow-up also showed a marked improvement in echocardiographic parameters (peak gradient 76.2 ± 26.1 vs 15.4 ± 7.8 mm Hg, P < .001; aortic valve area 0.7 ± 0.1 vs 2.6 ± 2.7 cm(2), P < .001) with a significant change in New York Heart Association class (3 ± 0.7 vs 1.2 ± 0.4, P < .001). Both preprocedural summary SF-36 and SF-12v12 physical and mental scores showed a significant improvement 1 year after TAVI (21.6 vs 46.7, P < .001; 42.9 vs 55.2, P < .001; 22 vs 48.9, P < .001; 43.3 vs 52.2, P < .001, respectively). Our results show a marked 1-year clinical benefit in functional status and physical and mental health in patients who underwent TAVI.
