Skeletonized bilateral internal mammary arteries for non-elective surgical revascularization in unstable angina.

OBJECTIVE: The aim of this study was to evaluate the feasibility, safety and outcome of skeletonized bilateral internal mammary arteries (BIMA) in patients with unstable angina (UA) undergoing non-elective myocardial revascularization. METHODS: Between January 1997 and December 2003, 758 patients, mean age 62+/-12 years, underwent non-elective coronary artery bypass grafting (CABG) for unstable angina. Two hundred and five (27%) were operated emergently and 503 (73%) urgently. BIMA were employed in 320 (42%) patients (Group B) and isolated left IMA and/or saphenous vein grafts in the remaining 438 (58%) patients (Group M). RESULTS: In-hospital mortality (B = 5.9% and M = 5.3%), and perioperative myocardial infarction (B = 2.2%; M = 1.96%) were similar between the two groups (P = ns). Actuarial survival at 1, 3 and 7 years was 98.7, 97.5 and 96.2% in B and 99, 94.3 and 88.4% in M (P < 0.05 at 7 years follow-up). At 7 years follow-up, the event-free cardiac survival (92 vs. 87%, P = 0.021), angina-free survival (98.6 vs. 94%, P = 0.039), reoperation-free cardiac survival (98 vs. 95%, P = 0.04) and infarct-free cardiac survival (98.7 vs. 96%, P = 0.05) were better in Group B. Multivariate analysis identified age > 65 years (P = 0.02), LVEF < 35% (P = 0.01), > 1 ischemic irreversible area (P = 0.03) as independent predictors for late deaths, while the use of the LIMA (P=0.006) and both mammary arteries (P=0.001) decreased the risk of late deaths. CONCLUSIONS: The use of BIMA in non-elective CABG for UA is safe and effective. Mid-term outcome, however, are superior with improved freedom from cardiac death, from coronary reintervention and from myocardial infarction.

Safety in the Use of Dexmedetomidine (Precedex) for Deep Brain Stimulation Surgery: Our Experience in 23 Randomized Patients

Objective: Evaluation of safety and efficacy of dexmedetomidine in deep brain stimulation (DBS) surgery. Materials and Methods: A cohort of 23 patients, candidates for DBS for Parkinson's disease, Tourette syndrome, or obsessive‐compulsive disorder, was randomized in two groups: dexmedetomidine group and control group. Standard anesthesiologic parameters were recorded and analyzed, together with the need for other medications. A ten‐degree scale (visual analog scale) assessing patient discomfort during DBS also was recorded at the end of surgery. Results: The results demonstrated good stability of intraoperative monitoring: no respiratory depression and good overall cooperation with the neurologist, while no side‐effects were recorded. Conclusions: Our conclusion is that dexmedetomidine should be considered as a valuable option for sedation in poorly collaborating patients undergoing DBS surgery.     

Mindful Coping and Mental Health among Adolescents

The aim of the research described here is to provide knowledge of adolescents and their coping strategies through the construct of mindful coping. Little is known about the contributions of mindfulness to the enhancement of mental health in adolescents. Inspired by dialectical behaviour therapy (Linehan, 1993a, b), we discuss the mindful coping process and investigate how different aspects of this process are related to mental health in a non-clinical adolescent sample. The empirical approach consisted of a cross-sectional study of 652 high-school students from two high schools, covering all streams. The relations between the four proposed mindful coping aspectsawareness, distraction, preventing negative emotions and constructive self-assertionwith psychological symptoms (PS), as well as how these four aspects moderated the relationship of perceived life strains (LS) with PS, were studied. The results show that coping by preventing negative emotions and constructive self-assertion were associated with fewer PS and/or weaker association between LS and PS, whereas coping by use of distraction was related to more PS and did not moderate the association between LS and PS. Finally, coping by use of awareness was related to a stronger association of LS with PS. The results only partly supported our expectations, providing challenging and important knowledge for future research on mindful coping in adolescents.
