Preoperative visit-care for transcatheter aortic valve replacement: a review.

Aim: The aim of this review is to evaluate and summarize the evidence for preoperative visit-care of transcatheter aortic valve replacement (TAVR) and to provide evidence-based support for clinical intervention.

Design: The review presents an evidence summary report, following the standard of the Fudan University Center for Evidence-based Nursing.

Methods: Literature related to preoperative visit-care for transcatheter aortic valve replacement have been retrieved based on the "6S" pyramid model of evidence.

Barriers and facilitators of the nurse providing evidence-based preoperative visit-care for transcatheter aortic valve replacement: a mixed-methods study based on an evidence application setting.

Background: Preoperative visit-care for transcatheter aortic valve replacement (TAVR) plays a crucial role in improving the quality of care and patient safety. However, preoperative care for TAVR patients is still in its early stages in China, with the care often being experience-based. The application of relevant evidence in nursing practice is necessary.

Capn4 overexpression indicates poor prognosis of ovarian cancer patients.

Recent studies have shown a close correlation between Capn4 expression and the prognosis of patients with solid tumors. This study aimed to investigate clinical role of Capn4 in ovarian cancer. The expression of Capn4 in 113 ovarian cancer and 35 non-tumor tissue samples were detected by quantitative real-time polymerase chain reaction (qRT-PCR).

Assessment of aortopulmonary collateral flow and pulmonary vascular growth using a 3.0 T magnetic resonance imaging system in patients who underwent bidirectional Glenn shunting.

Objectives: To explore the feasibility of evaluating the aortopulmonary collateral flow (APCF) and pulmonary vascular growth of patients who underwent bidirectional Glenn shunting (BGS) using phase-contrast magnetic resonance imaging (PC-MRI) and contrast-enhanced magnetic resonance imaging (CE-MRI).

Methods: Blood flow measurements of the great vessels of the body were recorded in 22 post-BGS patients using 3.0 T PC-MRI.

2-amino and 2'-aminocombretastatin derivatives as potent antimitotic agents.

A novel series of 2-amino and 2'-aminocombretastatin derivatives were synthesized and evaluated for antitumor activity. Several compounds had excellent antiproliferative activity as inhibitors of tubulin polymerization. Compounds 11, 20, and 21 with IC(50) values of 1.
