The purpose of this study was to evaluate the elastic memory process in cold worked stainless steel wire and the effect of heat treatment on it. 0.018 inch round and 0.019 X 0.025 inch rectangular wire (ORMCO stainless wire) were used in this study. Each wire type had 4 groups: non-heat treatment group, furnace heat treatment group, electric current heat treatment group, and bending after heat treatment group. Each group was consisted of 10 specimens. With the Jig, each wire was bent into v-shape uniformly, and width of two free ends of each v-shaped wire was measured by caliper (to the point of 0.1mm correctly) at time interval of off-jig, after heat treatment, 1, 2, 3. 4 hours, I, 2, 3,4, 5, 6 days, 1, 2, 3, 4 weeks after. The results were as follows: 1. In non-heat treatment group and bending after heat treatment group, elastic memory process was occured 60% within 1 hour, and more than 90% within 1 week. 2. In furnace and electric current heat treatment group, almost all elastic memory process was occured during heat treatment, and then specimen was stabilized dimensionally. 3. Magnitude of deformation by elastic memory was greater in heat treatment group than non heat treatment group and bending after heat treatment group. 4. There was no remarkable difference in deformation pattern between 0.018 inch round wire and 0.019 x 0.025 inch rectangular wire.

BACKGROUND: Depletion of nutritional reserves and significant weight loss can lead to an increased risk of morbidity, reduced chemotherapy response, and shorter survival in patients with cancer. Numerous methodologies are used for the assessment of nutritional status. However, it remains unclear which of these tools is the most appropriate in the setting of cancer chemotherapy. The PINI (prognostic inflammatory nutritional index) is a simple scoring system that has been used to evaluate nutritional status and prognosis in critically ill patients. The aim of this study was designed to investigate the relationship between nutritional status after the palliative chemotherapy and prognosis in advanced metastatic cancer. METHODS: This study included 130 patients with ECOG PS (Eastern Cooperative Oncology Group performance status) 1~3 in advanced metastatic cancer following the palliative chemotherapy. ECOG PS, body mass index, alpha 1-acid glycoprotein, C-reactive protein, albumin, prealbumin, transferrin, protein, lactate dehydrogenase, PINI ratio, and survival time were evaluated. RESULTS: In 130 patients, the median age was 57 years. The ECOG PS was 1 68 patients, 2 43, 3 19. The mean value of PINI was PS 1 16.0+/-47.8, PS 2 55.6+/-106.9, PS 3 106.3+/-141.6. The mean survival was PS 1 144.0+/-71.8, PS 2 68.9+/-41.2, PS 3 32.0+/-6.9 days. In the PS 3 group, the mean values of alpha 1-acid glycoprotein, C-reactive protein, and lactate dehydrogenase were significantly higher than in the PS 1 group. In the PS 3 group, the mean values of albumin, prealbumin, and transferrin were significantly lower than in the PS 1 group. The survival time was correlated with the ECOG PS (r=-0.602, p<0.001,), PINI (r=-0.318, p<0.001,), alpha 1-acid glycoprotein (r=-0.265, p=0.002), C-reactive protein (r=-0.345, p<0.001), albumin (r=0.324, p<0.001), prealbumin (r=0.260, p=0.003) and transferrin (r=0.277, p=0.001). CONCLUSIONS: The PINI may be a useful scoring system for the assessment of nutritional status and prognosis in advanced metastatic cancer following palliative chemotherapy, but the ECOG PS is most strong correlation with the survival time.

BACKGROUND: A1chieve(R) was a noninterventional study evaluating the clinical safety and efficacy of biphasic insulin aspart 30, insulin detemir, and insulin aspart. METHODS: Korean type 2 diabetes patients who have not been treated with the study insulin or have started it within 4 weeks before enrollment were eligible for the study. The patient selection and the choice of regimen were at the discretion of the physician. The safety and efficacy information was collected from the subjects at baseline, week 12, and week 24. The number of serious adverse drug reactions (SADRs) was the primary endpoint. The changes of clinical diabetic markers at week 12 and/or at week 24 compared to baseline were the secondary endpoints. RESULTS: Out of 4,058 exposed patients, 3,003 completed the study. During the study period, three SADRs were reported in three patients (0.1%). No major hypoglycemic episodes were observed and the rate of minor hypoglycemic episodes marginally decreased during 24 weeks (from 2.77 to 2.42 events per patient-year). The overall quality of life score improved (from 66.7+/-15.9 to 72.5+/-13.5) while the mean body weight was slightly increased (0.6+/-3.0 kg). The 24-week reductions in glycated hemoglobin, fasting plasma glucose and postprandial plasma glucose were 1.6%+/-2.2%, 2.5+/-4.7 mmol/L, and 4.0+/-6.4 mmol/L, respectively. CONCLUSION: The studied regimens showed improvements in glycemic control with low incidence of SADRs, including no incidence of major hypoglycemic episodes in Korean patients with type 2 diabetes.
