Abstract

The structure of the title adduct comprises a phenanthroline derivative 2-phenyl-imidazo[4,5-/]1,10-phenanthroline and a methanol. The composition of the crystalline adduct was characterized as C19H12N4 CH3OH. It belongs to orthorhombic system, space group Pna21 with a = 1.3693(4) nm, b = 2.2988(7) nm, c =0.51338(15) nm, V = 1.6160(8) nm3, Z = 4, and final R1 = 0.0423, wR2 = 0.1012. Crystal structure shows that all the 19 carbon atoms and 4 nitrogen atoms are coplanar. The bond length data indicated that a very extensive conjugation system was formed. This conjugation makes the compound being a potentially excellent energy transformer used for luminescent materials.

Abstract

Background: The aim of this study was to investigate the relation between surgeon age and in-hospital mortality for patients who underwent a coronary artery bypass graft (CABG) using a nationwide population-based data set., Methods: This study used data from the 2004 Taiwan National Health Insurance Research Database. The study sample comprised 3766 patients hospitalized for CABG surgery and was divided into three equal-sized surgeon age groups: <40, 40 to 45, and >45 years. A conditional (fixed-effect) logistic regression was performed to examine the relation between surgeon age and in-hospital mortality after adjusting for surgeon CABG caseload and characteristics of patients and surgeons as well as the clustering effect among surgeons., Results: Patients who underwent CABG performed by surgeons in the <40 years age group had significantly higher in-hospital mortality rates (5.4%) than those operated on by surgeons in the 40- to 45-year age group (3.5%) and surgeons in the >45-year age group (2.6%). Regression shows that the adjusted odds ratio of in-hospital mortality for patients operated on by surgeons in the <40-year age group was 1.47 (p < 0.05) times that for surgeons in the 40- to 45-year age group and 1.82 (p < 0.05) times that for surgeons in the >45-year age group., Conclusion: We conclude that older surgeons are more likely to achieve better clinical performance with CABG surgery because of their greater clinical experience.
