PURPOSE: To separate and evaluate the low frequency spontaneous fluctuation BOLD signals from the functional magnetic resonance imaging data using sensorimotor active task. MATERIALS AND METHODS: Twenty female archery players and twenty three control subjects were included in this study. Finger-tapping task consisted of three cycles of right finger tapping, with a subsequent 30 second rest. Blood oxygenation level-dependent (BOLD) data were collected using T2*-weighted echo planar imaging at a 3.0 T scanner. A 3-D FSPGR T1-weighted images were used for structural reference. Image processing and statistical analyses were performed using SPM5 for active finger-tapping task and GIFT program was used for statistical analyses of low frequency spontaneous fluctuation BOLD signal. RESULTS: Both groups showed the activation in the left primary motor cortex and supplemental motor area and in the right cerebellum for right finger-tapping task. ICA analysis using GIFT revealed independent components corresponding to contralateral and ipsilateral sensorimotor network and cognitive-related neural network. CONCLUSION: The current study demonstrated that the low frequency spontaneous fluctuation BOLD signals can be separated from the fMRI data using finger tapping paradigm. Also, it was found that these independent components correspond to spontaneous and coherent neural activity in the primary sensorimotor network and in the motor-cognitive network.

BACKGROUND: Quinidine appeared to increase serum digoxin levels when given with quinidine. Therefore elevated serum digoxin concentrations and clinical toxicity have been reported in patient receiving quinidine. Currently, Bayesian method which estimates the most probable parameters of the drug for each patient from population parameters data is useful approach for adjusting digoxin dosage. To increase the accuracy of Bayesian method, it is desirable to use population parameters of Korean. Therefore we evaluated the effect of quinidine on digoxin clearance in Korea. METHOD: Patient's records from 19 adult cardiac disease without CHF having normal renal and liver function from Seoul National University of Hospital respectively wre evaluated. Digoxin pharmacokinetic parameters, CL and Vd, were obtained from serum concentration of digoxin of single and combined therapy at each steady-state by using bayesian method. RESULTS: This study show that quinidine reduced the total body clearance of digoxin from 2.39+/-0.17 to 1.51+/-0.08ml/min/kg(p<0.05) and reduced the digoxin volume of distribution from 8.57+/-0.29 to 4.98+/-0.19L/kg(p<0.05). This results show that digoxin dosage reduced to 40-50% in Korean, if quinidine therapy is initiated.

STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

Meckel's diverticulum is found in about 3% of the population, often incidentally during laparotomy or at autopsy. Over 50% of patients who develop symptoms from this anomaly are younger than 2 years of age. The most common symptom of this lesion is intestinal obstruction. Rarely Meckel's diverticulum is complicated by a mesodiverticular band, which is believed to be a remnant of a vitelline artery. We report a 11-year-old girl with small bowel obstruction because of an intestinal hernia beneath the mesodiverticular band. The causative factor was a stenotic area in the terminal ileum caused by a ringlike lipovascular mesenteric band encroaching externally on the lumen. Although the incidence of mesodiverticular bands complicating Meckel's diverticulum is quite low, the rapid clinical course and the associated high mortality rate make this an important disease.

Purpose: This pilot study aimed to examine the influence of death counseling on perceptions, preparedness, and anxiety regarding death and dying among family caregivers of hospice patients. Methods: Death counseling developed based on the SPIKES model was provided to 37 family caregivers in a hospice and palliative care unit. Perceptions, preparedness, and anxiety regarding death were assessed with a self-administered structured questionnaire, and participants’ scores before and after counseling were compared using the paired t-test. Results: Significant changes were found in perceptions, preparedness, and anxiety regarding death after counseling. Compared to before counseling, the scores for perceptions of death (t=-4.90, P＜0.001) and preparedness for death and dying (t=-16.23, P＜0.001)improved, while anxiety (t=3.72, P=0.001) decreased after counseling. Some changes were also found in the types of support that family caregivers needed to prepare for the death of their family members in the hospice care unit. Conclusion The findings demonstrate that death counseling could help family caregivers prepare for the death of their loved ones.Hospice and palliative care providers should play a key role in supporting family caregivers of hospice patients by developing strategies for counseling.

Background: Remimazolam is a novel short-acting benzodiazepine. This study compared the effects of remimazolam and propofol on cognitive function in adult patients after surgery or other procedures. Methods: We searched electronic databases, including PubMed, Embase, CENTRAL, Web of Science, and Scopus, for relevant studies. The primary outcome was the proportion of participants who experienced delirium or impaired cognitive function postoperatively. Secondary outcomes included the incidence of hypotension, bradycardia, and postoperative nausea and vomiting. We estimated the odds ratios (OR) and mean differences (MD) with 95% CIs using a random-effects model. Results: In total, 1295 patients from 11 randomized controlled trials were included. The incidence of postoperative delirium was 8.0% in the remimazolam group and 10.4% in the propofol group that was not significantly different (OR: 0.74, 95% CI [0.39–1.42], P = 0.369, I2 = 32%). More favorable cognitive function, as assessed using the Mini-Mental State Examination, was observed in the remimazolam group compared to the propofol group (MD: 1.06, 95% CI [0.32–1.80], P = 0.005, I2 = 89%). Remimazolam lowered the incidence of hypotension (OR: 0.28, 95% CI [0.21–0.37], P = 0.000, I2 = 0%) compared to propofol. Conclusions Remimazolam did not increase the risk of postoperative delirium and maintained cognitive function well, providing hemodynamic stability during surgery compared to propofol.
