28. Changing Approaches to Methodology of Research in Special Education.

Author

Hulek, Alexander

Abstract

Special education research conducted during 1976 through 1980 at Warsaw University is summarized according to research methodology. The author presents nine conclusions from the research, including that disabled people are capable of much more than was previously thought and that understanding of specific types of disabilities must be coupled with knowledge of commonalities.

Abstract

Purpose: To evaluate the effects of secondary deployment of expanded polytetrafluoroethylene (ePTFE)-covered stent grafts in the treatment of dysfunctional transjugular intrahepatic portosystemic shunts (TIPSs) in comparison with other common approaches (conventional angioplasty or implantation of bare metal stents). Materials and Methods: A retrospective review of 121 dysfunctional bare metal TIPS presenting between 2000 and 2004 was conducted. The group was divided into four subgroups according to the type of intervention: conventional angioplasty (52 cases; 43%), bare metal stent deployment (35 cases; 28.9%), nondedicated ePTFE-covered stent-graft deployment (15 cases; 12.4%), and dedicated ePTFE-covered stent-graft deployment (19 cases; 15.7%). In all four groups, the primary patency after the specific intervention was calculated and mutually compared. Results: Primary patency rates after 12 and 24 months were 49.7% and 25.3%, respectively, in conventional angioplasty; 74.9% and 64.9%, respectively, with bare metal stents; 75.2% and 64.5%, respectively, with nondedicated ePTFE-covered stent grafts; and 88.1% and 80.8%, respectively, with dedicated ePTFE-covered stent grafts. Conclusions: In the treatment of dysfunctional TIPS, better patency after the intervention was obtained by deploying dedicated ePTFE-covered stent grafts in comparison with conventional angioplasty, bare metal stents, and nondedicated ePTFE-covered stents.

Abstract

Background. Transjugular intrahepatic portosystemic shunts (TIPS) have become a widely accepted tool in the treatment of patients with symptomatic portal hypertension. The aim of our study was to assess glycogen phosphorylase BB (GPBB) concentration in relation to echocardiographic and haemodynamic parameters in patients before and after TIPS insertion. Methods. The study population consisted of 55 patients (38 men and 17 women, age 55.6±8.9 years, range 37-74 years) with liver cirrhosis treated with transjugular portosystemic shunting. GPBB, echocardiographic, and haemodynamic parameters were measured before TIPS insertion and 24 h after the procedure. GPBB concentrations were assessed using the Cardiac Array for Evidence Investigator protein biochip. Correlation between parameters was assessed using the Spearman's coefficient. Results. Serum post-procedural GPBB concentrations were increased in comparison with baseline (5.58 vs. 2.67 µg/L, P<0.001). GPBB concentration after TIPS significantly correlated with baseline systemic vascular resistence (r=0.330; P=0.017) and cardiac index (r=0.313; P=0.025). Conclusion. GPBB concentration measurement may be a useful tool for monitoring myocardial ischemia during a TIPS procedure. [ABSTRACT FROM AUTHOR]
