Shaping classroom social experiences through collaborative small-group discussions.

Background: Students form interpersonal and intrapersonal classroom social experiences with peers. While diverse intervention programmes have been developed, few have integrated social-emotional learning into academic activities to maximize the potential for learning and development.

Aims: This study examined the effects of collaborative small-group discussions on students' classroom social experiences at the interpersonal and intrapersonal levels.

Teacher Scaffolding of Social and Intellectual Collaboration in Small Groups: A Comparative Case Study.

This comparative case study features two small groups of students engaging in collaborative dialog about social issues. Based on social constructivist theories, the two groups were compared across three major components of the small groups system: social dynamics, intellectual collaboration, and teacher scaffolding. Our goal was to holistically analyze these small group processes to understand why some small groups were highly successful while others were not, even within the same intervention and with the same teacher.

Acute kidney injury after transcatheter aortic valve implantation: Impact of contrast agents, predictive factors, and prognostic importance in 203 patients with long-term follow-up.

Background: Acute kidney injury (AKI) frequently occurs following transcatheter aortic valve implantation (TAVI) and has been related to a worse outcome. We investigated the importance of contrast medium composition, either iso-osmolar (IOCM) or low-osmolar (LOCM) and assessed predictors for AKI after TAVI.

Methods And Results: We assessed AKI in 203 TAVI patients treated mainly with trans-femoral implantation and analgosedation.

Transcatheter aortic valve implantation in patients with severely reduced left ventricular systolic function: a single-center experience.

Aims: Current guidelines consider severe systolic left ventricular dysfunction [ejection fraction (EF) ≤20 %; left ventricular dysfunction (LVD)] a contraindication for transcatheter aortic valve implantation (TAVI). The purpose of this study was to evaluate the efficacy and safety of TAVI in this extreme risk subset of patients.

Methods And Results: The study population (253 patients) was divided into two groups; the LVD group [21 patients with left ventricular ejection fraction (LVEF) ≤20 %] and the control group (232 patients with LVEF >20 %).

[Atrial myxoma with clinical signs of systemic inflammatory disease].

Atrial myxomas are detectable in 0.3 % of all autopsies and women are affected three times more often than men. The overall incidence of myxoma is relatively rare with 0.
