BACKGROUND: Obesity is known to influence on physical, mental, functional health problems but there have been no study of relationship between body mass index (BMI) and quality of life (QOL) in Korean elderly. METHODS: A total of 216 elderly who had been attending two geriatric welfare facilities in Seoul answered the Korean version of obesity-related quality of life (KOQOL) questionnaire. Height, weight, waist circumference were measured. Body fat (%) was measured with HTM20 by impedance technique. Sociodemographic and medical factors were interviewed. QOL was assessed using KOQOL (ver.1) after excluding two sexual life related questions and one work related question. The total score is 48 points. The higher is the score, the poorer is the QOL. RESULTS: In multivariable analysis, BMI, age, history of diabetes mellitus, history of osteoarthritis were associated with KOQOL score. Especially, BMI was significantly associated with KOQOL score after adjusting for waist circumference, body fat (%) (P = 0.002). CONCLUSION: The more BMI increases, the worse the obesity related QOL is in Korean ambulatory elderly.

BACKGROUND: The product of oxygen-free radicals inf1ict oxidative injuries on healthy cells. Antioxidants such as superoxide dismutase(SOD), glutathione peroxidase, and reduced glutathione(GSH) are present in almost all cells and play important roles in metabolism, transport, and cellular protection. We measured blood GSH levels in healthy controls and patients with non insulin dependent diabetes mellitus(NIDDM) for evaluation of the clinical usefulness of GSH. METHODS: Erythrocyte GSH levels were measured in fifty healthy controls and thirty NIDDM patients with diabetic retinopathies by Beutler's method. We also tested within-run precision, between-run precision, linearity and recovery rate to evaluate this method measuring erythrocyte GSH levels. RESULTS: The GSH levels (mean +/-SD) of NIDDM patients (5.03+/-0.67mumo1/Hb) were significantly lower than those of healthy control group (6.46+/-0.85mumo1/Hb)(P<0.001). The results of within-run precision and between-run precision when stored at 4degrees Cwere excellent (coefficient of variation were 2.79% and 2.42%, respectively), however, when stored at the room temperature the GSH levels were sharply declined. The linearity and recovery rate were acceptable. CONCLUSIONS: The prescision, linearity, and recovery rate of GSH measurement were excellent. The GSH levels in NIDDM patient group were reduced, and this probably contributes to the defective defense mechanism against increased oxidative stress. Additional measurement of other antioxidants such as superoxide dismutase and glutathione Peroxidase may be required to clarify the pathologic significance of glutathione metabolism in various diseases.

BACKGROUND: Anesthetic technique for laryngeal microscopic surgery should be focused on rapid recovery of deep anesthesia and full muscle relaxation. This study was taken to evaluate the effect of continuous infusion of propofol and succinylcholine for this kind of anesthetic goal. METHODS: Forty patients scheduled for laryngeal microscopic surgery of short duration(15 min) were randomly allocated into two groups. Anesthesia was induced and maintained with either propofol(2.5 mg/kg followed by a continuous infusion of 0.1 mg/kg/min) in group P or with thiopental (5.0 mg/kg) and inhalation of 1~2 vol % enflurane for maintenance of anesthesia in group T/E. Succinylcholine(1 mg/kg followed by continuous infusion of 0.1 mg/kg/min) was administered to facilitate tracheal intubation and maintain neuromuscular blockade. RESULTS: No significant difference of duration of anesthesia appeared between two groups. Additional doses of succinylcholine were needed in 10% of group P and 30% of group T/E (p<0.05). In group P, time to response to suction catheter(136+/-54 vs 232+/-116 sec), time to eye open spontaneously or to verbal commands (368+/-142 vs 549+/-165 sec) and time to extubation (454+/-117 vs 647+/-181 sec) were significantly shorter comparing to group T/E. The quality of awakening was more favorable in group P(p<0.05). Laryngeal suspension induced bradycardia in 15% of group P and in 5% of group T/E. Both group P and group T/E (10% vs 30%) needed esmolol infusion to control the blood pressure during surgical procedure. CONCLUSIONS: Rapid recovery of anesthesia and muscle relaxation can be expected after continuous infusion of propofol(2.5 mg/kg followed by 0.1mg/kg/min) and succinylcholine(1 mg/kg followed by 0.1 mg/kg/min) supplemented with 50% N2O in 50% O2 for short duration of laryngeal microscopic surgery.

OBJECTIVES: This study was conducted to evaluate the adoption behavior of a newly developed Electronic Medical Record (EMR)-based information system (IS) at three public hospitals in Korea with a focus on doctors and nurses. METHODS: User satisfaction scores from four performance layers were analyzed before and two times after the newly develop system was introduced to evaluate the adoption process of the IS with Rogers' diffusion theory. RESULTS: The 'intention to use' scores, the most important indicator for determining whether or not to adopt the IS in Rogers' confirmation stage for doctors, were very high in the third survey (4.21). In addition, the scores for 'reduced medication errors', which is the key indicator for evaluating the success of the IS, increased in the third survey for both doctors and nurses. The factors influencing 'intention to use' with a high odds ratio (>1.5) were the 'frequency of attendance of user training sessions', 'mandatory use of system', 'reduced medication errors', and 'reduced medical record documentation time' for both doctors and nurses. CONCLUSIONS: These findings show that the new EMR-based IS was well accepted by doctors. Both doctors and nurses also positively considered the effects of the new IS on their clinical environments.

The recording of middle cerebral artery (MCA) flow veloeity by transcrsnisl Doppler technique offers s new, noninvasive, and continuous technique for studies of cerebral circu lation. The influence of changes in PaCO2 on MCA flow velocity were observed during hypothermic cardiopulmonary bypass(CPB) surgery by means of transcranial Doppler tech- niques. In ten patients who were undergoing hypothermic CPB surgery, the right MCA flow velocity was measured before initiation of CPB(prebypass period) and after the termination of CPB (postbypass period). During steady state CPB(constant hematocrit, constant temperature, and constant total pump flow), baseline MCA flow velocity(CPB I period) was measured and then repeated after specific alteration of PaCO2 achieved by changing of fresh gas flow to oxygenetors(CPB II period). And carbon dioxide reactivity defined as percent change of MCA flow velocity per mmHg changes in PaCO2 was observed during stable hypothermic CPB. MCA flow veocity showed no statistical difference between the prebypass value(56.9+/-13.5 cm/sec) and the postbypass value(64.7+/-29.7 cm/sec). PaCO2 of 20.5+/-2.5 mmHg was associated with MCA flow velocity of 25.2+/-10.1 cm/sec in the CPB I period while PaCO2 of 27.1+/-3.5 mmHg was associated with MCA flow velocity of 35.3+/-12.9 cm/sec. MCA flow velocity carbon dioxide reactivity during steady state hypothermie CPB was 6.68+/-2.26 %/ mmHg. These results have demonstrated that the response of MCA flow velocity to changes in PaO2 was well maintained during hypothermic CPB and the use of transcrsnial Doppler would give valuable results in the study of cerebral circulation during hypothermic CPB.

We studied the effect of stellate ganglion block on the mean blood flow velocity and carbon diaxide reactivity of the middle cerehral artery in nine healthy volunteers. Mean blood flow velocity of the right middle cerebral artery was measured under normocapnia and carbon dioxide reactivity to end-tidal PCO2 of 30 mmHg, 40 mmHg, and 50 mmHg was assessed before and after right stellate ganglion block. End-tidal PCO2 was controlled by hyperventilation and rebthing technique. Mean blood flow velocity was measured using transcranial Doppler sonography, and carbon dioxide reactivity was expressed as the percentage change in mean blood flow velocity per unit change in end-tidal PCO2. There was no difference in mean blood flow velocity under normocapnia (37.7+/-1.1 mmHg) between the values measured before stellate ganglion block (60.3+/-4.9 cm/sec) and the values measured after stellate ganglion block (58.6+/-4.9 cm). Mean blood flow velocity increased as end-tidal PCO2 increased from 30 mmHg to 40 mmHg, and from 40 mmHg to 50 mmHg (p<0.01) both before and after stellate ganglion block. Carbon dioxide reactivity of mean blood flow velocity did not change after stellate ganglion block. Heart rate decreased from 77.1+/-3.5 beats/min to 70+/-2.5 beats/min when end-tidal PCO2 was controlled from 30 mmHg to 40 mmHg after stellate ganglion block (p<0.05). Mean arterial blood pressure did not change after stellate ganglion block at any end-tidal PCO2 level. These results suggest that stellate ganglion block does not induce the change of mean blood flow velocity and carbon dioxide reactivity of the middle cerebral artery.
