OBJECTIVES: Anticardiolipin antibody (ACA) and lupus anticoagulant (LA) are acquired antiphospholipid antibodies (APAs), which are regarded as important risk factors far vascular thrombosis and recurrent fetal loss. Although the clinical relevance of APAs in dialysis patients is uncertain, recent studies have suggested that APAs are involved in bioincompatibility and thrombogenic complications in hemadialysis (HD) patients. METHOD: We performed a cross sectional study of ACA and LA in 50 stable HD patients and their 68 vascular accesses (52 native arteriovenous fistulae and 16 synthetic arterovenous grafts), with the analysis of factors associated with the presence of APAs and the retrospective evaluation of vascular access occlusion (VAO). LA was assessed by platelet neutralization method whereas IgG-ACA was measured by a solid phase ELISA. Values higher than 23GPLU/ml (IgG phospholipid units) were considered to be positive for IgG-ACA and positive values for LA was more than 8 seconds in prolongation of the clotting time with human platelet lysate. Vascular access survival was assessed by Kaplan- Meier method, RESULTS: The mean age of the subject (M:F 21:29) was 46 years and the mean duration of hemodialysis was 49 months. The frequency of VAO in entire subjects was 0.45+/-0.98 episodes/patient year. The median value of IgG-ACA was 16.0 GPLU/ml with a distribution from 2.7 to 46.1GPLU/ ml. The median titer of I.A was 4.5 (3.1-45.6) seconds. Fourteen patients (28%) were found to have at least one episode of VAO. In spite of comparable clinical and biochemical data according to the presence of VAO, the titers of IgG-ACA (13.6+/-7.7 vs, 20.3+/-8.7GPLIJ/ml, P<0.05) and LA (4.5+/-2.9 vs. 11.7 +/-12.6sec, P<0.05) were significantly higher in VAO group. Six out of 50 patients(12%) had an increased titer of IgG-ACA and LA was found in 11 patients(22%). No patients were positive for ACA and LA simultaneously. There was no significant difference in sex, etiology of ESRD, diabetic status, the dosage of heparin during HD or the amount of erythropoietin administered according to the presence of APAs. We could not find any significant correlation between the titer of APAs and age, duration of dialysis, blood pressure, platelet count and biochemical parameters. In the patients with positive ACA, the frequency of VAO was 1.05+/-0.12 episodes/patient year, which was significantly higher than patients without ACA (0.33+/-0.17 episodes/ patient year, P<0.05). In the patients with the presence of LA(1.06+/-0.43 vs. 0.12+/-0.06 episodes/ patients year, P<0.01). The median vascular access survival time in IgG-ACA positive patients (32.7 months) was significantly decreased compared to 66.8 months in IgG-ACA negative group. CONCLUSION: Our data suggest that the presence of APAs (ACA and/or LA) affects the event-free vascular access survival in HD patients. Therefore the evaluation of APAs status have to be included in the diagnostic strategies for the patients with recurrent VAO. Further studies are necessary to explore the pharmacologic intervention method to decrease APAs and prevent VAO in HD patients.

OBJECTIVES: This study aims to analyze the association between the severity of sleep apnea, sleep and mood related scales, and activity during sleep in obstructive sleep apnea syndrome (OSAS) patients. METHODS: One hundred seventy six drug-free male patients confirmed as OSAS (average age=43+/-11 years) were selected through nocturnal polysomnography (NPSG). OSAS was diagnosed with apnea-hypopnea index (AHI) >5, mean AHI was 39.6+/-26.0. Sleep related scales were Stanford Sleepiness Scale (SSS), Epworth Sleepiness Scale (ESS), Pittsburg Sleep Quality Index (PSQI) and Morningness-Eveningness Scale (MES). Mood related scales were Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), State-Trait Anxiety Inventory (STAI) I, II and Profile of Mood States (POMS). NPSG was performed overnight with both wrist actigraphy (WATG). Parameters produced from WATG were total activity score, mean activity score and fragmentation index. We analyzed the correlation between each scale, AHI scored from NPSG and activity score analyzed from WATG. RESULTS: ESS showed significant positive correlation with PSQI, BDI, BAI and STAI I, II, respectively (p<0.01). SSS showed significant positive correlation with PSQI and BAI (p<0.05, p<0.01). BAI showed significant positive correlation with total activity score, mean activity score and fragmentation index (p<0.05, p<0.01, p<0.05). Total activity score showed significant positive correlation with ESS and BAI, respectively (p<0.05). Fragmentation index showed significant positive correlation with ESS, PSQI and BAI (p<0.05, p<0.01, p<0.05). AHI, indicator of sleep apnea is showed no significant correlation with each sleep and mood related scale. CONCLUSION: The degree of daytime sleepiness tends to be associated with night sleep satisfaction, depression and anxiety, and the activity during sleep rather than the severity of sleep apnea.

BACKGROUND: The aim of this study is to evaluate the influence of immunosuppressants on in-hospital mortality from sepsis. METHODS: Using data of the Health Insurance Review & Assessment Service, we collected data from patients who were admitted to the hospital due to sepsis from 2009 to 2013. Based on drugs commonly used for immunosuppression caused by various diseases, patients were divided into three groups; immunosuppressant group, steroid-only group, and control group. Patients with no history of immunosuppressants or steroids were assigned to the control group. To identify risk factors of in-hospital mortality in sepsis, we compared differences in patient characteristics, comorbidities, intensive care unit (ICU) care requirements, and immunodeficiency profiles. Subgroup analysis according to age was also performed. RESULTS: Of the 185,671 included patients, 13,935 (7.5%) were in the steroid-only group and 2,771 patients (1.5%) were in the immunosuppressant group. The overall in-hospital mortality was 38.9% and showed an increasing trend with age. The steroid-only group showed the lowest in-hospital mortality among the three groups except the patients younger than 30 years. The steroid-only group and immunosuppressant group received ICU treatment more frequently (p < 0.001), stayed longer in the hospital (p < 0.001), and showed higher medical expenditure (p < 0.001) compared to the normal group. Univariate and multivariate analyses revealed that age, male gender, comorbidities (especially malignancy), and ICU treatment had a significant effect on in-hospital mortality. CONCLUSIONS: Despite longer hospital length of stay and more frequent need for ICU care, the in-hospital mortality was lower in patients taking immunosuppressive drugs than in patients not taking immunosuppressive drugs.

PURPOSE: We evaluated a rapid preparation procedures for the labeling and quality control of 99mTc-ECD, MAG3, and MIBI using microwave heating and Sep-Pak cartridges. MATERIALS AND METHODS: 99mTc labeling of ECD, MAG3, and MIBI kit preparation was performed according to the package inserts with microwave heating modification. Heating time was 10-15 sec, and heating was performed with 3 mm plastic bottle with screw cap to prevent radiation contamination. Labeling efficiency was obtained with C18 or Alumina N Sep-Pak cartridges. RESULTS: The radiochemical purity of 93~96% for 99mTc-ECD and 95~99% for 99mTc-MIBI was obtained using Alumina N Sep-Pak cartridge. The optimum irradiation time of microwave method for 3 ml 99mTc-labeled radiopharmaceutical solution was 10 sec for 99mTc-ECD and 99mTc-MIBI, and 15 sec for 99mTc-MAG3. The RESULTS of quality control data with Sep-Pak cartridges were well correlated with TLC method. The total preparation time of these radiopharmcaeuticals was 5~6 min including quality control procedure. CONCLUSION: This study demonstrates that radiopharmaceuticals preparation by microwave heating and quality control by Sep-Pak cartridges can be efficiently utilized as an alternative to the recommended method by manufacturer's manual.

PURPOSE: This study carried out a preliminary analysis of available literature and used the ecological approach to define a research hypothesis with focus on individual, family, and school variables related to early adolescents' urge to run away. This study also aimed to examine the influence of each of these variables in order to build a forecast model showing which variables have more influential on early adolescents' urge to run away. METHODS: Materials were collected from 433 male and female fifth- and sixth-grade students at two schools in Gyeonggi Province. Analysis was carried out using SPSS/WIN 18.0. Frequency analysis, chi2-test, t-test, correlation analysis and logistic regression analysis were conducted. RESULTS: The results indicate that personal factors related to runaway impulse are gender and previous runaway attempts, family-related factor family functionality, and school-related factor the area of stress from study. CONCLUSION: Based on the study results as above, individual, family, and school interventions need to be developed.
