Intermittent cold blood cardioplegia with retrograde coronary perfusion was demonstrated in 11 CABG cases and the effects of myocardial protections were compared with 11 cases of antegrade perfusion. We evaluated the effects from the assistant perfusion time after aortic declamping, the incidence of occurrence of spontaneous beating, the dose of catecholamin required after CPB, and the changes in myocardial enzyme values. The two groups were similar in age, ejection fractions, and the extent of coronary artery disease. There were no cases of death and no PMI in all 22 cases, and the mean number of grafts and aortic clamping time were similar in the two groups. Concerning the effects of myocardial protections, there were no significant differences in any items in the two groups. We conclude that intermittent cold blood cardioplegia with retrograde coronary perfusion provides the same myocardial protective effects as the antegrade perfusion in CABG cases.

Purpose : This study aimed to explore the factors which interfere with advance decision-making with regards to artificial hydration and nutrition (AHN) in the senescent population.
Methods : Subjects were local residents aged 60 years or older who were leading an independent life and who could go out by themselves. A cross-sectional study using a self-administered questionnaire was conducted from August to November 2011. Valid responses were obtained from 116 subjects, for a valid response rate of 90.6%. Advance AHN decisions, knowledge about AHN, intentions regarding advance directives and end-of-life care, experience providing long-term care, in addition to other questions, were analyzed using a multiple logistic regression model.
Results : With respect to advance decisions regarding AHN, 25 respondents (21.6%) indicated that they could not make a decision, while 91 respondents (78.4%) could. Sixteen respondents (13.8%) desired some component of AHN, while 75 respondents (64.7%) did not desire any AHN. Factors related to difficulty with advance decisions regarding AHN were : 1) lack of adverse experiences associated with decreased cognitive function (“experience of failure”) (OR=12.0, 95%CI=1.42-100.41, p<.022), 2) lack of experience providing long-term care for a family member (“experience of caring”) (OR=3.0, 95%CI=1.04-8.53, p<.042), and 3) desire to defer such decisions to others in the event of unconsciousness or other incompetency rather than an advance decision (“reliance on others”) (OR=5.6, 95%CI=1.95-16.24, p<.001).
Conclusion : Factors related to difficulty with advance decisions regarding AHN in the senescent population were lack of adverse experiences associated with decreased cognitive function, lack of experience providing long-term care for a family member, and desire to defer such decisions to others in the event of unconsciousness or other incompetency rather than an advance decision.

The purpose of this study was to determine sway characteristics of a supported leg during a lateral stepping over obstacle task with different obstacle height and movement patterns, using a small triaxial accelerometer. We examined 20 healthy young adults to assess their trochanter malleolar distance traveled during a lateral stepping over obstacle task with obstacle heights of 30%, 50%, and 70%. The lateral stepping over tasks revealed flexion and extension patterns. We directed the subjects to grasp a forward handrail, perform the lateral step, and subsequently step over to the side. We calculated synthetic acceleration (SA) from acceleration data measured using two small triaxial accelerometers and two web cameras. We calculated supporting leg sway; RMS phases of X-, Y-, and Z-axes; and SA data. The subjects showed increased RMS of Y-axis and SA according to the obstacle height for the flexion pattern; however, they did not show change in RMS of Y-axis and SA according to the obstacle height for the extension pattern. During lateral stepping over, the RMS of Y-axis and SA for the flexion pattern were higher than for the extension pattern. The findings for the flexion pattern suggest that the center of gravity shifts higher according to increased obstacle height; consequently, the supporting leg becomes unstable. The findings for the extension pattern suggest that the “screw-home” rotation effect of the supporting leg during movement can support lateral stepping over better than the flexion pattern.

A 51-year-old female inserted a needle through the chest wall in a suicide attempt. Chest roentgenogram showed the needle located in the cardiac shadow and chest CT showed the needle penetrating into the ventricular wall. We removed the needle through median sternotomy. The needle had penetrated the right ventricular myocardium 2mm from the LAD. The tip of the needle reached the diaphragm and the surface of the diaphragm had been injured by the needle. The needle was removed without any difficulty and she was discharged 14 days after the operation.
