The use of a mini bypass circuit for minimally invasive mitral valve surgery

Introduction: The purpose of the study is to clinically evaluate minimally invasive mitral valve surgeries (MIMVS) using a mini bypass circuit. The challenge to perfusion is to keep pace with MIMVS, with demonstrated improvements in perfusion-related technologies. Methods: From October 28, 2005 to September 10, 2008, we retrospectively evaluated thirty-four elective cases which used the mini-circuit (Medtronic Resting Heart System®), with respect to safety, efficacy, cannulation technique, blood usage, resultant hemoglobin, length of ICU and hospital stay, and complications. Conclusion: The Medtronic Resting Heart System® alleviates many factors, such as high shear stress, turbulence, air to blood interface and decreased oncotic pressure caused by hemodilution, providing more efficient perfusion to our MIMVS patients. We demonstrate, with minor circuit modifications and attention to venous air issues, that this mini-circuit can be used safely and effectively, while being associated with improvements in patient outcomes.

Music: a source of deep imaginative satisfaction?

This paper gives the first insight into the establishment and development of the Strathclyde Consortium for Action Research in Learning Approaches and Teaching Techniques in Inventing (SCARLATTI) Project, and reflects on the changes to the music curriculum in Scottish secondary schools over the last twenty years. There is evidence to support the view that Inventing is an area of the curriculum which is causing music teachers some anxiety (Sheridan, 1992) and this paper examines the teaching and learning of the skills required of both teachers and pupils for the Inventing element of Standard Grade music (Byrne, 1996). The authors have launched an action research music project (Bresler, 1995; Adelman & Kemp, 1992; Treacher, 1989) which it is hoped will refocus the thinking of music teachers in schools by creating a dynamic network to provide a forum for the discussion of ideas and a means whereby experiences and materials can be shared, and new approaches and methods considered and implemented. A feature of the SCARLATTI project is a World Wide Web discussion group that will provide a communication link for schools involved in the project as well as a platform for teachers to air issues, ideas and views.

Struggling with Identity: Working with Seventh- and Eighth-Grade Gifted Girls to Air Issues of Concern

When adolescent girls are also identified as gifted, the problems of conformity, peer acceptance, and low self-esteem often become exacerbated. Middle school girls seem most vulnerable to two competing demands: popularity versus academic achievement. As a result of parental, staff, and student concerns, I have been conducting a “women's issues” group with 7th- and 8th-grade gifted girls for the last four years. The issues discussed, the materials used, and the outcomes I have seen are the themes of this action research paper.
