Abstract
Background/Aims Risk factors for progression to critical illness in hospital-acquired coronavirus disease 2019 (COVID-19) remain unknown. Here, we assessed the incidence and risk factors for progression to critical illness and determined their effects on clinical outcomes in patients with hospital-acquired COVID-19. Methods This retrospective cohort study analyzed patients admitted to the tertiary hospital between January 2020 and June 2022 with confirmed hospital-acquired COVID-19. The primary outcome was the progression to critical illness of hospital- acquired COVID-19. Patients were stratified into high-, intermediate-, or low-risk groups by the number of risk factors for progression to critical illness. Results In total, 204 patients were included and 37 (18.1%) progressed to critical illness. In the multivariable logistic analysis, patients with preexisting respiratory disease (OR, 3.90; 95% CI, 1.04-15.18), preexisting cardiovascular disease (OR, 3.49; 95% CI, 1.11-11.27), immunocompromised status (OR, 3.18; 95% CI, 1.11-9.16), higher sequential organ failure assessment (SOFA) score (OR, 1.56; 95% CI, 1.28-1.96), and higher clinical frailty scale (OR, 2.49; 95% CI, 1.62-4.13) showed significantly increased risk of progression to critical illness. As the risk of the groups increased, patients were significantly more likely to progress to critical illness and had higher 28-day mortality. Conclusions Among patients with hospital-acquired COVID-19, preexisting respiratory disease, preexisting cardiovascular disease, immunocompromised status, and higher clinical frailty scale and SOFA scores at baseline were risk factors for progression to critical illness. Patients with these risk factors must be prioritized and appropriately isolated or treated in a timely manner, especially in pandemic settings.

Abstract
AIM To evaluate the relationship between dental calcification and skeletal maturity and to identify the tooth with the highest correlation with skeletal maturity index in Korean children. MATERIALS For 447 children (205 boys and 242 girls) aged between 5 and 13 years, hand-wrist and lateral cephalometric radiographs were taken to assess skeletal maturity by Fishman's skeletal maturity indicators (SMI) and Baccetti's cervical vertebrae maturation (CVM) stages. Dental panoramic radiographs were taken to assess dental maturity of the permanent mandibular canine, first and second premolar, and second molar using the method devised by Dermirjian. CONCLUSION Dental calcification stages determined by panoramic radiographs can be clinically used as useful indices to predict skeletal maturity in Korean children.

Abstract
UNLABELLED The population-based cohort study used the Korean National Health Insurance claims database to evaluate the effect of anti-diabetic drugs on osteoporosis. The use of DPP-IV inhibitors does not increase the risk of osteoporosis compared with the use of sulfonylureas in patients with type 2 diabetes mellitus, while a weak association was found between thiazolidinediones and increased risk of osteoporosis. PURPOSE The current study aimed to evaluate the effect of dipeptidyl peptidase IV inhibitors (DPP-IVi), thiazolidinedione (TZD), and sulfonylurea (SU) on osteoporosis in patients with type 2 diabetes. METHODS A population-based cohort study was conducted in the Republic of Korea using the Korean National Health Insurance claims database. Data from 2012 to 2017 for patients of 50-99 years of age who were prescribed DPP-IVi, TZD, or SU during 2013-2015 were extracted from the database. Based on pre-defined criteria, a total of 381,404 patients were analyzed after inverse probability of treatment weighting. The association between the study drugs and osteoporosis was estimated using Cox proportional hazards models. Data of 220,166 patients who were prescribed DPP-IVi, 18,630 who were prescribed TZD, and 142,608 patients who were prescribed SU were set. RESULTS In the multivariate-adjusted analysis, the hazard ratio (HR) of osteoporosis in the DPP-IVi group was not significantly different from that of the SU group (HR: 0.97; 95% confidence interval (CI) 0.94-1.00), whereas the HR of osteoporosis in the TZD group was higher (HR: 1.13; 95% CI 1.06-1.20). In the subgroup analysis, the HRs of osteoporosis were higher with pioglitazone (HR: 1.14; 95% CI 1.06-1.23) in the TZD group and with glibenclamides (HR: 1.39; 95% CI 1.09-1.77) in the SU group, whereas drugs with lower HR in the DPP-IVi group were saxagliptin (HR: 0.93; 95% CI 0.87-0.99) and sitagliptin (HR: 0.93; 95% CI 0.89-0.97). CONCLUSION DPP-IV inhibitors do not increase the risk of osteoporosis compared with sulfonylureas in patients with type 2 diabetes mellitus, while a weak association was found between thiazolidinediones and increased risk of osteoporosis.

Abstract
BACKGROUND The aim of this study was to compare olfactory function change in patients who underwent endoscopic skull-base surgery. METHODOLOGY A total of 928 patients were included in this retrospective study. Olfactory function was measured using the non- validated Likert scale (0â€"100), the Cross-Cultural Smell Identification Test (CC-SIT) and the butanol threshold test (BTT). Patients were divided into two groups: an endoscopic trans-sellar approach group (ETA, n = 768) and an extended endoscopic endonasal approach group (EEEA, n = 160). The ETA group was sub-divided into Nasoseptal flap (NSF) and no NSF groups. RESULTS Non-validated olfactory function significantly worsened in the EEEA and ETA-NSF groups compared with that in the ETA- no NSF group for at least 6 months post-operatively. Validated olfactory impairment (BTT and CC-SIT) was also significantly worse in the EEEA and NSF groups compared with that in the ETA-no NSF group 3 months post-operatively. Additionally, the degrees of non-validated and validated olfactory deterioration were not significantly different between the EEEA and ETA-NSF groups. We also found that CC-SIT score changes were significantly impaired in tuberculum sellae meningioma patients than in craniopharyn- gioma patients. CONCLUSIONS We conclude that NSF was the key factor that led to olfactory impairment after endoscopic skull-base surgery.

Abstract
An in vitro differentiation system utilizing retinoic acid (RA) treatment of pluripotent murine P19 embryonal carcinoma (EC) cells, which can be induced to differentiate into various cell types, was optimized for maximal induction of alpha 1 type I collagen (Col1a1) gene expression. Differentiation was associated with apoptotic death of the majority of cells, indicating that this in vitro system faithfully mimics the in vivo differentiation process. Col1a1 mRNA became detectable by RNase protection assay after 3 days of RA treatment and, after 6 days, reached a level comparable to that in NIH 3T3 fibroblasts. After induction of differentiation the Col1a1 gene remained transcriptionally active for extended periods of time even in the absence of RA. A minigene version of the murine Col1a1 gene was constructed that contains all of the so far known Col1a1 regulatory elements. This construct exhibited the correct expression pattern in stable transfection experiments: it was expressed in fibroblasts, but not in undifferentiated P19 EC cells, and it was transcriptionally activated after induction of differentiation. This experimental system should be a useful tool for dissecting the molecular mechanisms involved in the developmental activation and stage- and tissue-specific expression of the murine Col1a1 gene.

Abstract
Food allergy is a major public health problem. Studies have shown that long-term interactions between activated leucocyte cell adhesion molecule (ALCAM/CD166) on the surface of antigen-presenting cells, and CD6, a co-stimulatory molecule, influence immune responses. However, there are currently no studies on the functions of ALCAM in food allergy. Therefore, we aimed to identify the functions of ALCAM in ovalbumin (OVA)-induced food allergy using ALCAM-deficient mice. Wild-type (WT) and ALCAM-deficient (ALCAM-/- ) mice were sensitized intraperitoneally and with orally fed OVA. The mice were killed, and parameters related to food allergy and T helper type 2 (Th2) immune responses were analysed. ALCAM serum levels increased and mRNA expression decreased in OVA-challenged WT mice. Serum immunoglobulin (Ig)E levels, Th2 cytokine mRNA and histological injuries were higher in OVA-challenged WT mice than in control mice, and these were attenuated in ALCAM-/- mice. T cell proliferation of total cells, CD3+ CD4+ T cells and activated T cells in immune tissues were diminished in OVA-challenged ALCAM-/- mice. Proliferation of co-cultured T cells and dendritic cells (DCs) was decreased by the anti-CD6 antibody. In addition, WT mice sensitized by adoptive transfer of OVA-pulsed ALCAM-/- BM-derived DCs showed reduced immune responses. Lastly, serum ALCAM levels were higher in children with food allergy than in control subjects. In this study, serum levels of ALCAM were elevated in food allergy-induced WT mice and children with food allergy. Moreover, immune responses and T cell activation were attenuated in OVA-challenged ALCAM-/- mice. These results indicate that ALCAM regulates food allergy by affecting T cell activation.

Abstract
OBJECTIVES To examine the association between nutritional status and frailty in older adults. DESIGN Cross-sectional study. SETTING Community-dwelling older adults were recruited from 10 study sites in South Korea. PARTICIPANTS 1473 volunteers aged 70-84 years without severe cognitive impairment and who participated in the Korean Frailty and Aging Cohort Study (KFACS) conducted in 2016. MEASUREMENTS Nutritional status was measured using the Mini Nutritional Assessment Short Form (MNA-SF). Frailty was assessed with the Fried's frailty index. The relationship between nutritional status and frailty was examined using the multinomial regression analysis, adjusting for covariates. RESULTS Of the respondents 14.3% had poor nutrition (0.8% with malnutrition, 13.5% at risk of malnutrition). There were 10.7% who were frail, with 48.5% being prefrail, and 40.8% robust. Poor nutrition was related to a significantly increased risk of being prefrail (odds ratio [OR]: 1.59, 95% confidence interval [CI]: 1.09-2.32) and frail (OR: 3.30, 95% CI: 1.96-5.54). CONCLUSION Poor nutritional status is strongly associated with frailty in older adults. More research to understand the interdependency between nutritional status and frailty may lead to better management of the two geriatric conditions.

Abstract
BACKGROUND Clusterin is a sensitive cellular biosensor of oxidative stress and has been studied as a biomarker for inflammation-associated diseases. Clusterin levels in childhood asthma have not been evaluated. OBJECTIVES (1) To evaluate sputum clusterin levels in children with asthma compared to a control group. (2) To assess the relationships between sputum clusterin levels and airway inflammation, pulmonary function, and bronchial hyperresponsiveness. METHODS This study included 170 children aged 5-18 years with stable asthma (n = 91), asthma exacerbation (n = 29), or no asthma (healthy controls; n = 50). Induced sputum, pulmonary function, and methacholine challenge tests were performed. Stable asthma was classified into two groups according to the severity. Clusterin levels in sputum were measured using an enzyme-linked immunosorbent assay. RESULTS Children with stable asthma had a higher clusterin level than healthy controls [4540 (3872-5651) pg/mL vs. 3857 (1054-4369) pg/mL, P < 0.001]. The clusterin level was also more elevated in eosinophil-dominant sputum than in non-eosinophilic sputum in stable asthma [5094 (4243-6257) pg/mL vs. 4110 (1871-4839) pg/mL, P = 0.0017]. Clusterin levels were associated with asthma severity. Paradoxically, clusterin levels were lower during asthma exacerbation than in stable asthma [1838 (350-4790] pg/mL vs. 4540 (3872-5651) pg/mL, P < 0.001]. Clusterin levels were strongly correlated with the methacholine concentration that caused a 20% decrease in the forced expiratory volume in 1 s (r = -0.617, P < 0.001); there was no significant correlation between clusterin levels and other pulmonary function parameters. CONCLUSIONS AND CLINICAL RELEVANCE Clusterin levels were altered in children with stable asthma and asthma exacerbation because of its antioxidant and anti-inflammatory effects. Clusterin may be a marker that reflects airway inflammation and severity of symptoms, and it can be used in the assessment and management of childhood asthma.

Abstract
Objectives We analyzed the clinical follow-up results of 88 lupus nephritis patients to find prognostic factors for the development of chronic kidney disease in ethnically homogeneous Korean patients with biopsy-proven lupus nephritis. Methods Sociodemographic, clinical, laboratory, and treatment-related data at the time of kidney biopsy and during follow-up were obtained. Renal biopsy specimens were reclassified according to the International Society of Pathology/Renal Pathology Society classification, separately, by two renal pathologists blinded to the previous classification. Univariate and multivariate analyses were performed using the Cox proportional hazard regression model to identify independent risk factors for chronic kidney disease in lupus nephritis patients. Results Eighteen of 88 patients (20.5%) developed chronic kidney disease during a mean follow-up of 47.6 months (range: 12–96 months). Patients who developed chronic kidney disease were older at onset of lupus nephritis, had less education, and were more likely to have hypertension; they had lower serum albumin levels, lower platelet levels, higher serum creatinine levels, lower estimated glomerular filtration rate, higher chronicity index, and lower frequency of anti-ribosomal P antibodies, and they were less likely to be in complete remission in the first year. In stepwise multivariable analyses, hypertension, lower glomerular filtration rate, and failure to achieve complete remission in the first year of treatment were significant predictors of the development of chronic kidney disease in lupus nephritis patients. Conclusions These findings suggest that patients with hypertension and decreased kidney function at the onset of lupus nephritis and showing a poor response to immunosuppressive drugs in the first year should be monitored carefully and managed aggressively to avoid deterioration of kidney function.

Peanut allergens share significant amino acid homology with those of other legumes and tree nuts, but their cross-reactivity still remains unclear. OBJECTIVE We sought to determine the clinical significance of the cross-reactivity of peanut allergens with those of walnut and soybean. METHODS Pooled sera from eight subjects with both peanut and walnut specific IgE were investigated in an inhibition test. After the sera were incubated with either peanut or walnut protein extracts, the quantity of IgE antibodies against the peanut and walnut was measured using an immunoCAP test. Likewise, pooled sera from 18 subjects with both peanut and soybean specific IgE antibodies were incubated with either peanut or soybean protein extracts and evaluated with a peanut and soybean immunoCAP test. SDS-PAGE and immunoblotting were also performed with peanut, walnut and soybean protein extracts and relevant sera. RESULTS Peanut specific IgE was inhibited up to 20% and 26% by walnut and soybean protein extracts, respectively. In reverse, walnut and soybean specific IgE were inhibited up to 21% and 23% by peanut protein extracts, respectively. In the immunoblot analysis, pooled serum from the subjects with peanut specific IgE antibodies reacted with walnut protein extracts significantly. CONCLUSION Although the clinical significance of the cross-reactivity of peanut specific IgE with walnut and soybean protein extracts has not been established, we believe that individuals who are allergic to peanuts need to be cautious about consuming walnuts and soybeans.

Abstract
Objectives The survival rate of patients with systemic lupus erythematosus has improved in the last few decades, but the rate of hospitalization and health care costs for these patients remain higher than in the general population. Thus, we evaluated the rate of hospitalization and associated risk factors in an inception cohort of Korean patients with lupus. Methods Of the 507 patients with systemic lupus erythematosus enrolled in the KORean lupus NETwork, we investigated an inception cohort consisting of 196 patients with systemic lupus erythematosus presenting within 6 months of diagnosis based on the American College of Rheumatology classification criteria. We evaluated the causes of hospitalization, demographic characteristics, and laboratory and clinical data at the time of systemic lupus erythematosus diagnosis of hospitalized patients and during a follow-up period. We calculated the hospitalization rate as the number of total hospitalizations divided by the disease duration, and defined "frequent hospitalization" as hospitalization more than once per year. Results Of the 196 patients, 117 (59.6%) were admitted to hospital a total of 257 times during the 8-year follow-up period. Moreover, 22 (11.2%) patients were hospitalized frequently. The most common reasons for hospitalization included disease flares, infection, and pregnancy-related morbidity. In the univariate regression analysis, malar rash, arthritis, pericarditis, renal involvement, fever, systemic lupus erythematosus disease activity index > 12, hemoglobin level < 10 mg/dl, albumin level < 3.5 mg/dl, and anti-Sjögren's syndrome A positivity were associated with frequent hospitalization. Finally, multivariate analysis showed that arthritis, pericarditis, and anti-Sjögren's syndrome A antibody positivity at the time of diagnosis were risk factors for frequent hospitalization. Conclusions Our results showed that frequent hospitalization occurred in 11.2% of hospitalized patients and arthritis, pericarditis, and anti-Sjögren's syndrome A antibody positivity at the time of diagnosis were risk factors for frequent hospitalization.

Abstract
Abstract
Background
Endocrine therapy (E) has a major role in treatment of hormone receptor (HR)-positive metastatic breast cancer (MBC). However, in contrast to western countries, premenopausal patients (PRE) more prevalent (50% of all breast cancer patients) and have less options of E than postmenopausal patients (POST) in Korea where the use of LHRH agonist in combination aromatase inhibitors (AIs) in PRE is restricted. Recently we have been successfully established nationwide cohort for the patients MBC (575 patients from 26 institutes). This study was designed to evaluate the role of E especially in PRE.
Methods
The patients with MBC were prospectively or retrospectively enrolled between September 2014 and May 2015. Only menopausal status-confirmed patients (296) were analyzed. Postmenopause was defined, based on NCCN guideline. Total duration of treatment was defined as the time from start day of any first treatment to end of any last treatment. Total duration of E was defined as the sum of time duration of each E. Overall survival was calculated from the start day of any treatment for MBC to any causes of death. This work is supported by National Strategic Coordinating Center for Clinical Research (H110C2020).
Results
A total of 296 patients with HR-positive MBC were analyzed [PRE, 169 (57.1%) and POST, 127 (42.9%)]. Except age (mean 44 and 60 years), baseline characteristics including in pathology, HER2 status, initial pathologic stage, de novo metastasis versus recurrence, surgery and adjuvant treatment (chemotherapy, endocrine therapy and radiotherapy) were well balanced. 92 (54.4%) of PRE and 77 (60.6%) of POST received at least one or more E through all treatment course. 41 (24.2%) of PRE and 44 (34.6%) received E as 1st-line treatment (p=0.034). Among PRE who received 1st-line of E, 30 (71.4%) and 9 (21.4%) of PRE received 2nd- and 3rd-line E. 20 (45.4%) and 10 (22.7%) of POST received 2nd- and 3rd- or more line of E. Most of PRE (54%) received tamoxifen+/-goserelin and 32% of PRE received AIs along with ovarian suppression. 71% of POST received AIs. As initial treatment, E was more frequently used in POST than in PRE (34.6% and 24.3%, p=0.053). Overall survival (OS) of all patients was 18.2 months (95% CI, 14.8-21.5). There was no difference in OS between PRE (17.8 months, 10.9-24.8) and POST (18.5 months, 95% CI, 13.2-23.9) (P=0.337). No difference of OS was observed (E, 18.1 moths, 95% CI, 13.0-23.3; chemotherapy 21.2 moths, 95% CI, 16.8-25.5), regardless of initial treatment. Total duration of treatment of PRE and POST were 15.2 and 13.6 months, respectively with no significant difference (p=0.389). PRE (8.3 moths, 95% CI,5.7-10.8) showed the trend toward longer duration of E in comparison with POST (5.5 moths, 95% CI,4.4-6.7), however the difference did not reach statistical significance (p=0.051).
Conclusion
E was more commonly used as 1st-line therapy in POST than in PRE. Although PRE had limited options of E, E was used in long duration of treatment especially in PRE. These findings suggested that E had a role in treatment for PRE with HR-positive MBC and could be used in treatment for PRE with good efficacy.

Abstract
Abstract
Background: It is well known that Wnt/β-catenin signaling pathway is involved in hormone receptor negative breast cancer, especially triple-negative breast cancer. In the case of hormone resistant breast cancer cells, they rarely showed hormone receptor expression. So we aimed to investigate whether the β-catenin pathway becomes activated in endocrine-resistant breast cancer cells and inhibition of β-catenin pathway can overcome endocrine resistance.
Methods: We have established an MCF-7-derived tamoxifen-resistant cell line (TamR) by long-term culture of MCF-7 cells with gradually increasing 4-hydroxytamoxifen concentration till 3μM. The levels of protein expression and mRNA transcripts were determined using western blot analysis and real-time quantitative PCR. The transcriptional activity of β-catenin was measured using luciferase activity assay. We used ICG-001 as inhibitor of β-catenin transcription activity.
Results: The expression of estrogen receptor was significantly decreased in TamR cells. On the other hand, the expressions of HER2 and EGFR were increased in TamR cells than in control cells. The active (uncomplexed form) β-catenin level was increased in TamR cells, and also showed a significantly increased β-catenin transcriptional activity. The ICG-001, small-molecular inhibitor of Wnt/β-catenin pathway, treatment significantly reduced β-catenin transcriptional activity in TamR cells. The ICG-001 reduced cell viability fo TamR cells which showed resistance to tamoxifen by 65.3%, and also inhibited target gene cyclin D1 expression. The combination of ICG-001 and mTOR inhibitor, rapamycin reduced cell viability of TamR cells by 81.7% and there was an additive effect of two drugs as a combination index of 1.022.
Conclusions: The β-catenin pathway is activated in endocrine-resistant breast cancer cells and inhibition of that pathway would be a new therapeutic strategy which overcomes endocrine resistance in breast cancer.

Abstract
Abstract
Background
Recently, many clinical trials (TRIAL) especially incorporated with molecular-targeted agents are being conducted in treatment for breast cancer worldwide. However, the relation of participating clinical trials with survival has not been actively studied. This study was designed to evaluate whether participation in clinical trials could improve overall survival (OS) or not in patients with metastatic breast cancer (MBC), compared with conventional treatment.
Method
Korean Cancer Study Group (KCSG) has successfully established Nationwide Cohort in KOREA to conduct diachronic analysis (KCSG BR 14-07). Clinical data for patients with MBC were collected from this Cohort. OS was defined as the time duration from first diagnosis of metastasis to any cause of death. This work is supported by National Strategic Coordinating Center for Clinical Research (H110C2020).
Results
A total of 575 patients with metastatic breast from 26 institutes in KOREA cancer MBC were consequently enrolled between September 2014 and May 2015. 156 (27.1%) of patients were enrolled to at least one or more clinical trials and 419 patients received only conventional treatment (CONV). Age, hormone status, HER2 status, initial pathologic stage, metastasis versus recurrence, adjuvant treatment, ECOG performance status (PS) (0, 1 vs 2 or more) were similar between TRIAL and CONV. 30% of trials were associated with HER2-targeted agents. As initial treatment, chemotherapy was more frequently used in TRIAL (85.9%) than in CONV (79.0%) (P=0.038). Number of regimens of chemotherapy was greater in TRIAL (2.9+/-1.8) than CONV (2.1+/-1.6) (P<0.001). Number of regimens of endocrine therapy (E) was similar between TRIAL (1.4+/-0.6) and CONV (1.5+/-0.7) (P=0.474). Overall survival of all patients was 16.2 months (95% CI, 14.1-18.1). TRIAL showed significant prolongation of survival, compared with CONV [21.1 (95% CI, 17.7-24.6) vs 15.1 months (95% CI, 13.1-17.2); P=0.005]. The differences in OS was constantly observed in HER2-positive [23.8 (16.7-30.9) vs 17.2 months (95% CI, 12.4-21.9); P=0.018] and Triple-negative [15.4 (10.5-20.3) vs 12.0 months (95% CI, 10.2-13.8); P=0.025]. In multivariate analysis, initial metastasis, hormone status, ECOG PS did not influence on OS between TRIAL and CONV (P=0.849)
Conclusion
Participating in clinical trials could be associated with prolongation of survival. This results constantly maintained in HER2-positive and triple-negative MBC. These findings suggested that clinical trials are useful for the patients with MBC, even if the patients do not complete the standard treatment.

Abstract
OBJECTIVES We investigated whether systemic lupus erythematosus (SLE) patients could be distinguished based on the time of disease onset and, if so, whether the groups differed in their clinical and laboratory features in ethnically homogeneous Korean patients. METHODS We enrolled 201 SLE patients with available clinical data at the time of onset of SLE from the lupus cohort at Chonnam National University Hospital. Sociodemographic, clinical, and laboratory data, including autoantibodies, and concomitant diseases were found at the time of diagnosis of SLE by reviewing patient charts. We divided SLE patients according to age at SLE diagnosis into three groups: juvenile-onset SLE (JSLE, diagnosed at ≤ 18 years), adult-onset SLE (ASLE, diagnosed at 19-50 years), and late-onset SLE (LSLE, diagnosed at >50 years), and compared baseline demographic, clinical, and relevant laboratory findings. RESULTS Of the 201 patients, 27 (14.4%), 149 (74.1%), and 25 (12.4%) were JSLE, ASLE, and LSLE patients, respectively. Fever, oral ulcers, nephritis, anemia, and thrombocytopenia were more common in JSLE patients than ASLE or LSLE patients (p < 0.05, < 0.05, 0.001, < 0.05, and < 0.05, respectively). However, Sjögren's syndrome was more frequent in LSLE patients than JSLE or ASLE patients (p < 0.05). Disease activity was significantly higher in JSLE patients than in ASLE or LSLE patients (p < 0.001). Anti-dsDNA and anti-nucleosome antibodies were found more frequently in JSLE patients and less frequently in LSLE patients (p < 0.05 and 0.005, respectively) and decreased complement levels were more common in JSLE patients and less common in LSLE patients (p < 0.001, 0.001, and < 0.05, respectively). CONCLUSIONS Our results indicate that SLE patients present with different clinical and serological manifestations according to age at disease onset. JSLE patients have more severe disease activity and more frequent renal involvement and LSLE patients have milder disease activity, more commonly accompanied by Sjögren's syndrome, at disease onset.

BACKGROUND AND PURPOSE Medullary thyroid carcinoma is an uncommon malignancy that is challenging to diagnose. Our aim was to present our experience using core needle biopsy for the diagnosis of medullary thyroid carcinoma compared with fine-needle aspiration. MATERIALS AND METHODS Between January 2000 and March 2012, 202 thyroid nodules in 191 patients were diagnosed as medullary thyroid cancer by using sonography-guided fine-needle aspiration, core needle biopsy, or surgery. One hundred eighty-three thyroid nodules in 172 patients were included on the basis of the final diagnosis. We evaluated the sensitivity and positive predictive value of fine-needle aspiration and core needle biopsy for the diagnosis of medullary thyroid cancer. We compared the rate of a delayed diagnosis, a diagnostic surgery, and surgery with an incorrect diagnosis for fine-needle aspiration and core needle biopsy and investigated the factors related to the fine-needle aspiration misdiagnosis of medullary thyroid cancer. RESULTS Fine-needle aspiration showed 43.8% sensitivity and 85.1% positive predictive value for the diagnosis of medullary thyroid cancer; 25.7% (44/171) of patients had a delayed diagnosis, while 18.7% (32/171) underwent an operation for accurate diagnosis, and 20.5% (35/171) underwent an operation with an incorrect diagnosis. Core needle biopsy achieved 100% sensitivity and positive predictive value without a delay in diagnosis (0/22), the need for a diagnostic operation (0/22), or an operation for an incorrect diagnosis (0/22). A calcitonin level of <100 pg/mL was the only significant factor for predicting the fine-needle aspiration misdiagnosis of medullary thyroid cancer (P = .034). CONCLUSIONS Core needle biopsy showed a superior sensitivity and positive predictive value to fine-needle aspiration and could optimize the surgical management in patients with medullary thyroid cancer. Because the ability of fine-needle aspiration to diagnose medullary thyroid cancer significantly decreases in patients with serum calcitonin levels of <100 pg/mL, core needle biopsy could be indicated for these patients to optimize their surgical management.

Abstract
WHAT IS KNOWN AND OBJECTIVE Pharmacogenetic studies of the genetic regulation of warfarin dose requirement have been reported, but few have been on the bleeding complications at therapeutic international normalized ratio (INR). This study aimed to evaluate the effect of gene polymorphisms of CYP2C9, VKORC1, thrombomodulin (THBD) and C-reactive protein (CRP) on the risk of bleeding complications of warfarin at therapeutic INR in Korean patients with mechanical cardiac valves. METHODS A retrospective warfarin pharmacogenetic association study was performed. One hundred and forty-two patients with mechanical cardiac valves who were on warfarin anticoagulation therapy and maintained INR levels of 2·0-3·0 for 3 consecutive time intervals were followed up. CYP2C9 rs1057910, VKORC1 rs9934438, CRP rs1205, THBD rs1042580 and THBD rs3176123 were genotyped. The association between genotypes and warfarin bleeding complications was evaluated using logistic regression analysis, adjusted for demographic and clinical factors. RESULTS AND DISCUSSION Of 142 eligible patients, 21 patients (14·8%) had bleeding complications at therapeutic INR. Patients with the G allele in THBD rs1042580 (AG or GG) had a lower risk of bleeding than patients with the AA genotype (adjusted OR: 0·210, 95% CI: 0·050-0·875, P = 0·032). The THBD rs3176123 polymorphism did not show any association with bleeding. For CRP rs1205, patients with the A allele (GA or AA genotype) had a higher risk of bleeding than patients with the GG genotype (adjusted OR: 5·575, 95% CI: 1·409-22·058, P = 0·014). Variant VKORC1 and CYP2C9 genotypes did not confer a significant increase in the risk for bleeding complications. WHAT IS NEW AND CONCLUSIONS As expected, no association could be found between bleeding complications and two dose-related genes (CYP2C9*3 and VKORC1 rs9934438). In contrast, our results suggest that two genetic markers (THBD rs1042580 and CRP rs1205) could be predictors of bleeding complications of warfarin at normal INR. Given the retrospective study design and the relatively small sample size, our hypothesis requires further independent validation using more robust prospective designs. However, additional retrospective studies similar to ours but in populations with different genetic backgrounds should also be useful.

Abstract
Oligodontia is the developmental absence of more than 5 permanent teeth except for the third molar. Familial oligodontia can occur as an isolated form or as part of a genetic syndrome. Mutations in the MSX1, PAX9, AXIN2, EDA, and WNT10A genes have been identified in familial non-syndromic oligodontia. Ectodermal dysplasia is a group of syndromes involving abnormalities of the ectodermal structures and is comprised of more than 150 different forms. Mutations in the ectodysplasin-A (EDA) gene have been associated with X-linked hypohidrotic ectodermal dysplasia, and partial disruption of the EDA signaling pathway has been shown to cause an isolated form of oligodontia. We identified 2 X-linked oligodontia families and performed mutational analysis of the EDA gene. The mutational analysis revealed 2 novel EDA mutations: c.866G>T, p.Arg289Leu and c.1135T>G, p.Phe379Val (reference sequence NM_001399.4). These mutations were perfectly segregated with oligodontia and curly hair within each family and were not found in the 150 control X-chromosomes with the same ethnic background and in the exome variant server. This study broadens the mutational spectrum of the EDA gene and the understanding of X-linked oligodontia with curly hair.

Abstract
The aim of our study was to assess the frequency of germline mutations and develop the genetic testing strategy in patients with apparently sporadic pheochromocytoma/paraganglioma (PPGL) in Korea. We included 53 patients diagnosed with non-syndromic PPGL without a family history of PPGLs in three referral centers from 2004 to 2011. Succinate dehydrogenase complex B (SDHB), SDHD, Von Hippel-Lindau (VHL), and rearranged during transfection (RET) genes were examined by direct sequencing and multiple ligation-dependent probe amplification. The study patients were composed of 26 men and 27 women, and mean age was 50.1 ± 13.5 years. The frequency of germline mutations was 13.2% (7/53): RET (n = 2), VHL (n = 1), SDHB (n = 2), and SDHD (n = 2). Six of seven mutation carriers were diagnosed before the age of 50. One of two patients harboring an SDHB mutation had malignant PPGLs. One patient with multifocal head and neck paraganglioma (PGL) and pheochromocytoma (PHEO) carried a SDHD mutation. The carriers of germline mutations in patients with apparently sporadic PPGL were 13.2% in our study. We recommend genetic testing in patients below 50 years and SDHD genetic testing in patients with multifocal PPGLs. In malignant PPGLs, SDHB genetic testing may be performed.

Abstract
Abstract
Background: S1 and oxaliplatin (SOX) combination chemotherapy is an effective regimen in anthracycline and taxane pretreated metastatic breast cancer (MBC) patients with manageable toxicities (KCSG BR07-03, SABCS 2011 #Abst P3-16-06). The aim of this study was to investigate the association of the single nucleotide polymorphisms (SNPs) and clinical outcome in MBC treated with SOX chemotherapy.
Patients and Methods: A total of 87 MBC patients previously treated with or resistant to anthracycline and taxane chemotherapy were enrolled in this prospective multicenter trial. The patients received S-1 80mg/m2/day (day 1–14) and oxaliplatin 130 mg/m2 (day 1) every 3 weeks till progression. Among the 87 patients, 77 patients were available for SNP analysis. Germline DNA from peripheral blood (PB) mononuclear cells was extracted. SNPs in 4 genes from pathways that may influence cellular sensitivity to S1 and oxaliplatin (TS, ERCC, XPD, and XRCC) were genotyped from PB sample using PCR-restriction fragment length polymorphism.
Results: Overall response rate (RR) was 38.5% (95% CI: 27.7–49.3) and disease control rate was 67.9% (95% CI:57.5–78.3) to SOX. Median time-to-progression (TTP) and overall survival (OS) were 6.0 mo (95% CI: 5.1–6.9 mo) and 19.4 mo (95% CI: not estimated), respectively. XRCC1 Arg194Trp SNP which participates in DNA repair mechanism showed correlation with the clinical outcome. RR was tend to higher in XRCC1 Arg194Trp CC genotype compared with CT or TT genotype (50.0 % vs 35.1% or 12.5%, P = 0.121). TTP of patients with CC genotype in XRCC1 Arg194Trp was significantly longer than the TTP of patients with CT or TT genotype (median TTP: 6.4 mo in CC, 5.9 mo in CT, 3.0 mo in TT, P = 0.007) as well as overall survival (OS) (median OS: not reached in CC, 13.9 mo in CT, 7.1 mo in TT, P = 0.006). After adjusting for hormone receptor status, performance status, and visceral involvement, prognostic value of XRCC1 Arg194Trp SNP remained significant (Hazard Ratio=1.322 and 4.484, P = 0.016). Other SNPs were not significantly associated with survival or toxicities.
Conclusion: XRCC1 Arg194Trp SNP is associated with clinical outcome of MBC patients treated with SOX chemotherapy. Further studies of the relationship between germline polymorphisms in XRCC1 and functional mechanism researches are warranted.

Abstract
BACKGROUND Cancer patients are at high risk for skin problems because rapidly proliferating skin cells are susceptible to anticancer therapies. However, the effects of daily skin care habits on development of skin problems in cancer patients have rarely been studied. PATIENTS AND METHODS We conducted a survey of daily skin care habits and the presence of skin problems in 866 cancer patients. RESULTS Hot water bath>1 h significantly increased the risk of definite eruptions [odds ratio (OR) 4.09] and the risk of itching or pain on the skin (OR 1.73). Diligent use of moisturizers did not decrease the risk of definite eruptions and symptoms, and daily bathing, scrubbing off the skin while bathing, and sun protection did not influence the risk of definite eruptions and symptoms. Subgroup analysis of 183 breast cancer patients showed results similar to the total results, including that hot water bath>1 h significantly increased the risk of definite eruptions (OR 3.41). CONCLUSIONS Being a cross-sectional study, our study could not prove causality. However, at the present stage of knowledge, avoidance of hot water baths of protracted duration should be first emphasized in patient education to prevent skin problems in cancer patients.

Abstract
Background
Oxaliplatin, a platinum analogue, is an active drug in advanced anthracycline and taxane-pretreated breast cancer patients as a single agent and with 5-fluorouracil (5-FU) combination. TS-1 was developed by the scientific theory of both potentiating antitumor activity of 5-FU and reducing gastrointestinal toxicity. This trial was performed to evaluate the efficacy and safety of TS-1 in combination with oxaliplatin in metastatic breast cancer (MBC) patients previously treated with anthracycline and taxane chemotherapy.
Methods: Between October 2007 and October 2009, MBC patients were enrolled in this prospective multicenter trial. Eligible criteria included age ≥18 years, at least one measurable lesion, prior treatment with anthracycline and taxane chemotherapy, and ECOG Performance Status 0–2. TS-1 40 mg/m2 b.i.d. on days 1–14 with oxaliplatin 130 mg/m2 on day 1 were administered every 3 weeks till disease progression. Primary end-point was response rate, and secondary end-points were time-to-progression (TTP), overall survival (OS), duration of response (DOR) and toxicities. Response was evaluated every 6 weeks according to the RECIST criteria v. 1.0 and toxicity was assessed with NCICTCAE v.3.0.(ClinicalTrials.gov identifier NCT00527930).
Results: A total of 87 patients were enrolled. Median age was 48 years (range 30–71 years). Nineteen patients (21.8%) had de novo stage IV and 68 patients (78.2%) had recurrent disease. Thirty-five patients (40.2%) received two-lines of prior chemotherapy in palliative setting. Forty-eight patients (55.2%) had ≥ 3 disease sites. Fifty-four patients (62.1%) were hormone receptor positive, and 25 patients (28.7%) were triple negative. Five patients received prior anti-HER2 therapy. A total of 525 cycles were administered (median 6 cycles, range: 1 ∼ 22+ cycle). In per-protocol analysis, overall response rate was 38.5% (95% CI: 27.7−49.3) (CR 0%, PR 38.5%) and disease control rate (CR, PR, and SD) was 67.9% (95% CI: 57.5−78.3). Median TTP, OS, and DOR were 6.0 months (95% CI: 5.1−6.9 months), 19.4 months (95% CI: not estimated), 6.6 months (95% CI: 3.7−9.6 months), respectively. RR was not different by triple negativity (39.1% in TNBC vs. 38.2% in non-TNBC, P=0.361). TTP was not different according to the number of prior chemotherapy regimens. Reported grade 3 or 4 toxicities (per cycle) were neutropenia (10.3%), thrombocytopenia (5.5%), diarrhea (1.9%), vomiting (1.9%), and stomatitis (0.2%). There was no treatment-related death.
Conclusions: SOX is an effective regimen in anthracycline and taxane pretreated MBC patients with manageable toxicities.

Abstract
AIMS/HYPOTHESIS To examine the association of serum cystatin C with the incidence of type 2 diabetes mellitus over a 15 year follow-up period. METHODS The 15 year cumulative incidence of diabetes was measured in a cohort of Beaver Dam Eye Study participants (n = 3,472, 1988-2003). A person was defined as developing diabetes (a positive history of diabetes mellitus treated with insulin, oral hypoglycaemic agents and/or diet, or elevations in glycosylated haemoglobin levels) in the absence of diabetes at baseline. The relation of cystatin C and other risk factors to incident type 2 diabetes was determined using discrete time extension of the proportional hazards model. RESULTS The 15 year cumulative incidence of diabetes was estimated to be 9.6%. After controlling for age, sex, body mass index, smoking status, glycosylated haemoglobin, proteinuria, chronic kidney disease status and hypertension status, serum cystatin C at baseline was associated with the 15 year cumulative incidence of type 2 diabetes (OR per log of cystatin C unit 2.19, 95% CI 1.02-4.68). CONCLUSIONS/INTERPRETATION These findings show a positive relationship of serum cystatin C levels with the incidence of type 2 diabetes mellitus independently of confounding risk factors. The findings strongly suggest the need for further evaluation of the potential importance of cystatin C in the pathogenesis of type 2 diabetes mellitus.

Abstract
From 2001 to 2008, a total of 27 isolates of Salmonella enterica serovar Typhimurium were obtained from 930 swine. All 27 isolates were resistant to streptomycin and tetracycline. Seventeen isolates were multidrug resistant to more than three antimicrobial agents. Seven of these multidrug-resistant isolates were pentaresistant to ampicillin, chloramphenicol, streptomycin, tetracycline, and nalidixic acid. Among 27 isolates, 14 isolates (51.8 %) were nalidixic acid resistant (MIC, ≥128 μg/ml) and had reduced susceptibility to various quinolones (MIC, 0.125 to 2 μg/ml). When quinolone resistance-determining regions in the gyrA and gyrB genes of these isolates were sequenced, 13 isolates had Asp87→Tyr mutations and 1 isolate had Asp87→Gly mutation in the quinolone resistance-determining region of gyrA, whereas no mutation was found in gyrB. Genes for qnrA, qnrB, and qnrS were not detected by PCR with specific primers. Pulsed-field gel electrophoresis of genomic DNA digested with Xba I showed two patterns suggesting a clonal spread of Salmonella Typhimurium in swine in Korea.

Abstract
Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly in the developed world. We conducted a genome-wide association study in a series of families enriched for AMD and completed a meta-analysis of this new data with results from reanalysis of an existing study of a late-stage case-control cohort. We tested the top findings for replication in 1896 cases and 1866 controls and identified two novel genetic protective factors for AMD. In addition to the complement factor H (CFH) (P=2.3 × 10⁻⁶⁴) and age-related maculopathy susceptibility 2 (ARMS2) (P=1.2 × 10⁻⁶⁰) loci, we observed a protective effect at rs429608, an intronic SNP in SKIV2L (P=5.3 × 10⁻¹⁵), a gene near the complement component 2 (C2)/complement factor B (BF) locus, that indicates the protective effect may be mediated by variants other than the C2/BF variants previously studied. Haplotype analysis at this locus identified three protective haplotypes defined by the rs429608 protective allele. We also identified a new potentially protective effect at rs2679798 in MYRIP (P=2.9 × 10⁻⁴), a gene involved in retinal pigment epithelium melanosome trafficking. Interestingly, MYRIP was initially identified in the family-based scan and was confirmed in the case-control set. From these efforts, we report the identification of two novel protective factors for AMD and confirm the previously known associations at CFH, ARMS2 and C3.

Abstract
Chitinases are produced in significant quantities by hosts defending against infections with chitin-containing organisms. However, little is known about the immune response of exogenous chitinase in human epithelial cells. IL-8 has been suggested to have a role in the pathogenesis of the allergenic inflammation of bronchial asthma. We examined whether Streptomyces griseus (S. griseus) chitinase-induced IL-8 on airway epithelium and identified the involvement of intracellular signalling pathways. H292 cells were treated with S. griseus chitinase with different concentrations and times. The IL-8 levels were determined by specific human IL-8 enzyme-linked immunosorbent assay (ELISA) and reverse transcriptase polymerase chain reaction. Using a series of pharmacological inhibitors, we examined the upstream signalling pathway responsible for IL-8 expression in response to S. griseus chitinase. Cells exposed to S. griseus chitinase showed higher level of IL-8 protein production and mRNA expression. Cells stimulated by S. griseus chitinase resulted in the activation of protein kinase C (PKC), extracellular signal-regulated kinase (ERK) and nuclear factor kappa-B (NF-kB) pathways. Inhibitors of Ca(2+)-dependent PKC (Ro-31-8220, calphostin C and Go6976) significantly abolished chitinase-induced expression of IL-8. However, Ca(2+)-independent PKC inhibitor (rottlerin) did not inhibit IL-8 expression. Through ERK inhibitor (U0126) and NF-kB inhibitor (caffeine acid phenethyl ester) treatment, it was proven that ERK and NF-kB regulated chitinase-induced IL-8 expression. We concluded that S. griseus chitinase-induced IL-8 expression was regulated by the activation of Ca(2+/-)-dependent PKC, ERK and NF-kB in human airway epithelial cells.

Abstract
Primitive neuroectodermal tumor is a rare brain tumor composed of undifferentiated or poorly differentiated neuroepithelial cells with a high malignant potential that usually occurs in children, and which is only occasionally encountered in adults. A 19-year-old female with systemic lupus erythematosus presented with right hemiparesis and a headache of 10 days duration. Brain magnetic resonance imaging showed a large solid mass with necrotic portions in the left frontoparietal lobe. Primitive neuroectodermal tumor was confirmed by a neuronavigator-guided brain biopsy. This is the first case report of primitive neuroectodermal tumor associated with systemic lupus erythematosus and moyamoya disease. This case demonstrates that brain tumors, such as primitive neuroectodermal tumor, should be included in the differential diagnosis of neurological manifestations in children and adolescent patients with systemic lupus erythematosus.

Abstract
AIM To assess the efficacy and safety of covered retrievable nitinol stents in oesophageal cancer patients with airway involvement. MATERIALS AND METHODS Under fluoroscopic guidance, covered retrievable nitinol airway stents were placed in 23 oesophageal cancer patients with airway stricture and/or oesophagorespiratory fistula (ERF) over a long period of 12 years. Six patients only had aspiration by ERF and three patients had both airway stricture and asymptomatic ERF. Technical aspects, dyspnoea improvement, and/or resolution of ERF symptoms, complications, reinterventions, and survival data were evaluated. RESULTS A total of 27 airway stents (14 tracheal, 11 bronchial, and two hinged) were placed successfully in 23 patients with airway stricture or ERF. Dyspnoea score decreased significantly after stent placement (p<0.001). ERF were sealed off in all nine patients. Complications included stent migration or expectoration (n=4), haemoptysis (n=2), sputum retention (n=7), and tumour overgrowth (n=1). All three migrated stents were easily removed. Twenty-one patients died, with the median survival period of 76 days (range 2-197 days). CONCLUSION Placement of covered retrievable expandable nitinol stents was safe and effective for the palliative treatment of airway strictures and/or ERF, with a reasonable range of complications, in patients with advanced oesophageal cancer.

Abstract
AIM To determine whether the immunohistochemical detection of syndecan-1 could provide useful information as a novel therapeutic or prognostic factor in primary gallbladder (GB) cancer. MATERIALS AND METHODS Forty-three GB cancer tissues were evaluated by immunohistochemistry for syndecan-1 expression. The relationship between syndecan-1 expression and clinicopathological characteristics, and the univariate survival analysis for the influence of the syndecan-1 expression on the overall survival were analysed. RESULTS Epithelial syndecan-1 immunoreactivity was observed in 25 (58.1%) of the 43 GB cancer cases. The tumors with a positive syndecan-1 expression more frequently showed lymph node metastasis (p = 0.037). Although there was no statistically significant association, the tumors with a positive syndecan-1 expression tended to show a deeper invasion depth (p = 0.087) and more frequent lymphovascular invasion (p = 0.064). The Kaplan-Meier survival curves demonstrated that patients with positive syndecan-1 expression had a significantly shorter survival time than those patients with negative syndecan-1 expression (p = 0.05). CONCLUSIONS A subset of GB cancers revealed an epithelial overexpression of syndecan-1, which was associated with a progressive pathological feature and an aggressive clinical course. Therefore, epithelial syndecan-1 expression may be a predictor for a poor prognosis in patients with GB cancer.

Abstract
Ce 4d-4f resonant angle-resolved photoemission spectroscopy was carried out to study the electronic structure of strongly correlated Ce 4f electrons in a quasi-two-dimensional nonmagnetic heavy-fermion system CeCoGe1.2Si0.8. For the first time, dispersive coherent peaks of an f state crossing the Fermi level, the so-called Kondo resonance, are directly observed together with the hybridized conduction band. Moreover, the experimental band dispersion is quantitatively in good agreement with a simple hybridization-band picture based on the periodic Anderson model. The obtained physical quantities, i.e., coherent temperature, Kondo temperature, and mass enhancement, are comparable to the results of thermodynamic measurements. These results manifest an itinerant nature of Ce 4f electrons in heavy-fermion systems and clarify their microscopic hybridization mechanism.

Abstract
The synthetic organic compound 4-nonylphenol (NP) has been detected in many human-impacted surface waters in North America. In this study, we examined the ability of NP to alter reproductive competence in male fathead minnows after a 28 day flow-through exposure in a range of environmentally relevant concentrations bracketing the U.S. Environmental Protection Agency toxicity-based NP chronic exposure criterion of 6.1 microg NP/L. Exposure to NP at and above the EPA chronic exposure criterion resulted in an induction of plasma vitellogenin (VTG) within 14 days. However, 7 days after the cessation of exposure, VTG concentrations had dropped more than 50% and few males expressed VTG above the detection threshold. All of the morphological endpoints, including gonadosomatic index, hepatosomatic index, secondary sexual characters, and histopathology, were unaltered by all NP treatments. However, when NP-exposed male fish were allowed to compete with control males for access to nest sites and females, most treatments altered the reproductive competence of exposed males. At lower NP concentrations, exposed males out-competed control males, possibly by being primed through the estrogenic NP exposure in a fashion similar to priming by pheromones released from female fathead minnows. At higher NP exposure concentrations, this priming effect was negated by the adverse effects of the exposure and control males out-competed treated males. Results of this study indicate the complexity of endocrine disrupting effects and the need for multiple analysis levels to assess the effects of these compounds on aquatic organisms.

Abstract
BACKGROUND Cockroaches have been known as a cause of respiratory allergies such as asthma. IL-8 plays an integral role in the coordination and persistence of the inflammatory process in the chronic inflammation of the airways in asthma. OBJECTIVE We investigated the mechanism by which German cockroach extract (GCE) triggers IL-8 release from human airway epithelial cells. METHODS Chemical inhibitors were pretreated before addition of GCE for promoter activity and protein synthesis of IL-8. The Transcriptional activity of IL-8 promoter was analysed by mutational, deletional anaylsis and electrophoretic mobility shift assay (EMSA). RESULTS Stimulation of H292 cells with GCE resulted in a time- and concentration-dependent induction of IL-8 transcription and protein synthesis. IL-8 promoter deletion analysis indicated that position -132 to +41 was essential for GCE-induced IL-8 transcription, and mutants with substitutions in activator protein (AP)-1, nuclear factor (NF)-IL6 and NF-kappaB-binding sites revealed a requirement for NF-kappaB and NF-IL6, but not AP-1, in GCE-induced activation of the IL-8 promoter. The DNA-binding activities of NF-kappaB and NF-IL6 were induced by GCE, as determined by EMSA. The chemical inhibition of extracellular signal-regulated kinase (ERK) attenuated GCE-induced transcriptional activity and protein synthesis. In addition, through aprotinin treatment and PAR2 small interfering RNA transfection, it was proven that protease of GCE is consistent with the regulation of GCE-induced IL-8. CONCLUSION We conclude that GCE with protease activity-induced IL-8 expression is regulated by transcriptional activation of NF-kappaB and NF-IL6 coordinating with the ERK pathway in human airway epithelial cells.

Abstract
INTRODUCTION Recent advances in magnetic resonance (MR) diffusion tensor imaging technique enable evaluation of the anisotropy of white matter tracts in-vivo, as well as the integrity of fibre tracts and their orientation. We describe our initial experiences with diffusion tensor imaging and MR tractography techniques to evaluate the structural degeneration of white matter tracts following stroke. METHODS Diffusion tensor imaging data were acquired in 11 cases with stroke on a 3T MR imaging scanner, with three-dimensional diffusion tensor imaging-based colour maps and MR tractography performed offline. We evaluated the spatial relationships of the eloquent white matter tracts to the infarcts and areas of haemorrhage, and classified therewith the tracts as either disrupted or displaced. We compared these with the clinical severity of the neurological deficits and prognosis. RESULTS A good correlation was found between tractography findings and patient's clinical recovery. All the patients with disruption of white matter tracts had residual deficits on clinical follow-up, whereas the patients with displaced tracts had near complete neurological recovery. CONCLUSION Diffusion tensor imaging and MR tractography provide a novel and useful method to directly visualise changes in the white matter tracts in stroke. This can potentially allow clinical-imaging correlation with prognostic potential.

Abstract
We consider the effect of geometrical configuration on the steady flow field of representative geometries from an in vivo anatomical data set of end-to-side distal anastomoses constructed as part of a peripheral bypass graft. Using a geometrical classification technique, we select the anastomoses of three representative patients according to the angle between the graft and proximal host vessels (GPA) and the planarity of the anastomotic configuration. The geometries considered include two surgically tunneled grafts with shallow GPAs which are relatively planar but have different lumen characteristics, one case exhibiting a local restriction at the perianastomotic graft and proximal host whilst the other case has a relatively uniform cross section. The third case is nonplanar and characterized by a wide GPA resulting from the graft being constructed superficially from an in situ vein. In all three models the same peripheral resistance was imposed at the computational outflows of the distal and proximal host vessels and this condition, combined with the effect of the anastomotic geometry, has been observed to reasonably reproduce the in vivo flow split. By analyzing the flow fields we demonstrate how the local and global geometric characteristics influences the distribution of wall shear stress and the steady transport of fluid particles. Specifically, in vessels that have a global geometric characteristic we observe that the wall shear stress depends on large scale geometrical factors, e.g., the curvature and planarity of blood vessels. In contrast, the wall shear stress distribution and local mixing is significantly influenced by morphology and location of restrictions, particular when there is a shallow GPA. A combination of local and global effects are also possible as demonstrated in our third study of an anastomosis with a larger GPA. These relatively simple observations highlight the need to distinguish between local and global geometric influences for a given reconstruction. We further present the geometrical evolution of the anastomoses over a series of follow-up studies and observe how the lumen progresses towards the faster bulk flow of the velocity in the original geometry. This mechanism is consistent with the luminal changes in recirculation regions that experience low wall shear stress. In the shallow GPA anastomoses the proximal part of the native host vessel occludes or stenoses earlier than in the case with wide GPA. A potential contribution to this behavior is suggested by the stronger mixing that characterizes anastomoses with large GPA.

Abstract
BACKGROUND/AIMS To assess the variability in retinal vessel measurements at different points in the pulse cycle. METHODS A healthy white male aged 19 years had 30 digitised images taken at three distinct points in the pulse cycle over a one hour period. A pulse synchronised ear clip trigger device was used to capture images at the desired point in the pulse cycle. Two trained graders measured the retinal vessel diameter of one large arteriole, one large venule, one small arteriole, and one small venule 10 times in each of these 30 images. RESULTS Within an image, variability was similar between graders, pulse point, and vessel type. Across images taken at the same point in the pulse period, the change from the minimum to maximum measurement was between 6% and 17% for arterioles and between 2% and 11% for venules. In addition, measurements of small vessels had greater changes than large vessels and no point in the pulse period was more variable than another. Ignoring pulse cycle increased variability across images in the large venule, but not in the other vessel types. Mixed effect models were fit for each of the vessel types to determine the greatest source of variability. Controlling for pulse point and grader, the largest source of variability for all four vessels measured was across images, accounting for more than 50% of the total variability. CONCLUSION Measurements of large retinal venules is generally less variable than measurements of other retinal vessels. After controlling for pulse point and grader, the largest source of variation is across images. Understanding the components of variability in measuring retinal vessels is important as these techniques are applied in epidemiological studies.

Abstract
A polymeric emulsion bead, which consists of core and capsule, was prepared. The core is composed of lipid nanoparticles containing lipophilic drug and semi-interpenetrating networks (semi-IPNs) are prepared to provide the capsule composed of sodium alginate and hydroxypropylmethyl cellulose (HPMC). The lipid nanoparticles were encapsulated into the polymeric emulsion bead with high drug loading efficiency, and lovastatin was used as a model drug. For the application as an oral drug delivery system, the enteric coating was performed with polymeric emulsion bead. The drug release pattern was controlled by the composition of capsule materials and environmental pH.

Abstract
AIM To investigate association of drug use and visual function. METHODS A cross sectional population based study was carried out on participants in the 1993-5 examination phase of the Beaver Dam Eye Study. All drugs in current use by study participants were recorded. Performance based and self assessed visual functions were obtained at the time of the study evaluation. The main outcome measure was the relation of levels of visual functions by use of specific drugs. RESULTS Many classes of drugs were associated with decreases in at least two performance based visual functions. For example, high blood pressure drugs were significantly associated with poorer best corrected visual acuity, poorer near vision, and poorer contrast sensitivity (p<0.001 for all). Patterns of association for self assessed visual functions were not as strong. However, use of glaucoma drops and benzodiazepines were associated with poorer self assessed visual functions in most circumstances cited. CONCLUSIONS Many commonly used medications are inversely associated with visual functions in a middle and older aged population. This may influence the ability to perform complex tasks and quality of life.

Abstract
The Nipah virus is a newly identified paramyxovirus responsible for an outbreak of fatal encephalitis in Malaysia and Singapore. This paper reports the follow up clinical and magnetic resonance imaging findings in 22 affected subjects. Of 13 patients with encephalitis, one died, one was lost to follow up, and seven recovered. Among the four remaining patients, one had residual sixth nerve palsy, another suffered from severe clinical depression, and a third patient had evidence of retinal artery occlusion. One patient with delayed onset Horner syndrome had a single lesion in the cervical spinal cord. The brain magnetic resonance findings were stable or improved in nine patients over 18 months of follow up. Among a second group of nine asymptomatic seropositive abattoir workers, magnetic resonance examination in seven subjects revealed discrete small lesions in the brain; similar to those detected in encephalitis patients. These findings suggest that in addition to encephalitis, the newly discovered Nipah virus affects the spinal cord and the retina. Late clinical and radiological findings can occur in Nipah virus infections as with other paramyxoviruses.

Abstract
BACKGROUND AND AIM Helicobacter pylori is considered as the major pathogen in Helicobacter pylori-associated gastroduodenal disease, but the mechanism of its action has not been fully explained. This study was performed to assess the reactive oxygen species activity and the damage in Helicobacter pylori-infected gastric mucosa. METHODS Gastric biopsy specimens were obtained from 308 patients undergoing endoscopy. Gastric mucosal damage was assessed by using luminol enhanced chemiluminescence, thiobarbituric acid-reactive substance, and mucosal glutathione. RESULTS The chemiluminescence and thiobarbituric acid-reactive substance-equivalent levels in the mucosa of patients with Helicobacter pylori-positive gastric mucosa (43.8 +/- 134.9 c.p.m./microg tissue, 157.0 +/- 96.2 nmol/g tissue, respectively) were significantly higher than in those with Helicobacter pylori-negative mucosa (6.8 +/- 20.3 c.p.m./microg tissue, 110.0 +/- 51.6 nmol/g tissue, respectively; P=0.000, P=0.016, respectively). The glutathione levels in the mucosa of patients with Helicobacter pylori-positive gastric mucosa (159.3 +/- 76.6 nmol/microg tissue) were significantly lower than in those with Helicobacter pylori-negative gastric mucosa (212.3 +/- 134.3 nmol/microg tissue; P=0.008). After the data were divided according to the presence of Helicobacter pylori, there were no significant differences in chemiluminescence, thiobarbituric acid-reactive substance, and glutathione among the different macroscopic findings within Helicobacter pylori-positive and -negative gastric mucosa. CONCLUSIONS Helicobacter pylori infection plays a pathological role in many gastrointestinal diseases through excessive mucosal-reactive oxygen species production, pronounced membrane damage, and the depletion of gastric anti-oxidants.

Abstract
OBJECTIVE To examine aggregation of refraction, myopia, hyperopia, and astigmatism, as well as the 5-year change in each of these measures, among adult family members. DESIGN Geographically defined, population-based cohort study in Beaver Dam, Wis. Participants were all 43 to 84 years of age in 1988. Family relationships among participants of the study were identified through interviews. The main outcome measures were noncycloplegic refractions. Aggregation was assessed by Pearson correlations and odds ratios (ORs) that both members of a pair were affected. RESULTS Age-adjusted sibling correlation of refraction was 0.37 and the OR for a sibling to be myopic was 4.18, whereas the OR for being hyperopic was 2.87 (all statistically significant, P<.05). Correlations and ORs for parent-child and cousin relationships were smaller, and those for spousal relationships were not significant. Correlations and ORs for cylinder power and astigmatism were not statistically significant for most relationships considered. There were no statistically significant correlations or ORs for changes in any measure of refractive error. CONCLUSIONS The strong aggregation of refractive error, including myopia and hyperopia, among siblings along with weaker associations among parent-child and cousin pairs and no associations among spouses suggest a potential genetic influence on refractive error. There is no such suggestion for a genetic influence on the changes in refraction or in cylinder power and astigmatism.

Abstract
PURPOSE To describe the change in visual acuity in a 10-year period. DESIGN Population-based cohort study. PARTICIPANTS Included 3684 persons 43 to 86 years of age at the time of a baseline examination in 1988 to 1990, living in Beaver Dam, Wisconsin, at a follow-up examination in 1993 to 1995 and/or 1998 to 2000. METHODS Best-corrected visual acuity was measured, after refraction, with logarithm of the minimum angle of resolution charts using a modification of the Early Treatment Diabetic Retinopathy Study protocol. MAIN OUTCOMES MEASURES Doubling of the visual angle and incidence of visual impairment. RESULTS The change in the mean number of letters read correctly over the 10-year period varied in the right eye from -0.9 (standard deviation [SD] = 5.5) and in the left eye from -1.2 (SD = 6.6) in people between 43 and 54 years of age to -11.0 (SD = 20.0) in the right eye and -12.6 (SD = 20.4) in the left eye in people 75 years of age or older (n = 184) at baseline. Over the 10-year period, 5.9% of the population had impaired vision (20/40 or worse in the better eye) develop, 0.8% had severe visual impairment (20/200 or worse in the better eye) develop, 4.8% had doubling of the visual angle, and 3.9% had improved vision. People who were 75 years of age or older at baseline were 15.0 times (95% confidence interval [CI], 10.9-20.6; P < 0.001) as likely to have impaired vision develop, 9.3 times (95% CI, 6.5-13.3; P < 0.001) as likely to have doubling of the visual angle, and 19.8 times as likely (95% CI, 8.4-46.4; P < or = 0.001) to have severe visual impairment develop than people younger than 75 years of age at baseline. For the 82 persons 75 years of age or older, currently residing in a nursing or group home at follow-up, they were 2.6 times (95% CI, 1.45-4.52) as likely to have impaired vision develop, 1.6 times (95% CI, 0.47-5.62) as likely to have severely impaired vision develop, and 3.6 times (95% CI, 1.96-6.78) as likely to have had a doubling of the visual angle than those not residing in a nursing or group home at follow-up. CONCLUSIONS These data provide precise population-based estimates of the 10-year incidence of loss of vision over a wide spectrum of ages and show that decreased visual acuity in people 75 years of age after 10 years is a common finding, especially in those who are admitted to nursing or group homes.

Abstract
OBJECTIVE To compare body mass index with waist-to-hip ratio as correlates of age-related eye disease. DESIGN Population-based cross-sectional study. PARTICIPANTS Participants of the Beaver Dam Eye Study at 5-year follow-up examinations. METHODS Body mass index was computed from weight and height, and waist-to-hip ratio was computed from measurements all done at the 5-year examination. Presence of ocular lesions was based on gradings of standard photographs of the retina and lens. MAIN OUTCOME MEASURES Presence of early and late age-related maculopathy and nuclear, cortical, and posterior subcapsular cataracts. RESULTS In women, early age-related maculopathy was significantly associated with both body mass index and waist-to-hip ratio. The relationship between waist-to-hip ratio and late age-related maculopathy was of borderline significance. When analyzed as continuous measures, waist-to-hip ratio was more strongly associated with nearly every outcome compared to body mass index. In men, there was little difference between body mass index and waist-to-hip ratio as correlates of age-related eye diseases. The reason for differences between men and women is not clear, but is unlikely to be due to current exposure to estrogen. CONCLUSIONS In women in our analyses, waist-to-hip ratio is more strongly associated with age-related eye disease than is body mass index. When adiposity is considered as a risk factor itself, or as a confounder of risk factors for age-related ocular disease, waist-to-hip ratio may be the better measure to use in women.

Abstract
OBJECTIVE To evaluate incident early age-related maculopathy (ARM) after a 5-year interval with respect to medication use. DESIGN Population-based incidence study. SETTING Participants were adults aged 43 to 86 years living in Beaver Dam, Wis, when first examined in 1988-1990 (n = 4926); they were reexamined in 1993-1995 (n = 3684). METHODS All participants were examined and interviewed and stereoscopic color fundus photographs were taken. All procedures were done by standard protocol at both examinations. Incidence of ARM was based on grading using the Wisconsin ARM Grading System. All prescribed and over-the-counter medications in current use were brought to the examination site and the names were recorded at that time. RESULTS There were 678 drug preparations (active ingredients) being used at the baseline examination. No relations were found between most antihypertensive drugs, most central nervous system medications, aspirin and other nonsteroidal anti-inflammatory agents, estrogens, lipid-lowering agents, and incident early ARM over the 5-year period. Age- and sex-adjusted logistic regression analyses suggested possible associations (P<.10) between the use of phenothiazine antidopaminergics (odds ratio [OR], 2.83; 95% confidence interval [CI], 0.97-8.23; P =.06), desiccated thyroid hormones (OR, 2.32; 95% CI, 0.89-6.07; P =.09), and calcium channel blockers (OR, 1.70; 95% CI, 0.93-3.12; P =.08) with incident ARM. When additional information on past use was included in the regression model, the association remained for calcium channel blockers, but not for phenothiazines and desiccated thyroid hormones. A lower incidence of early ARM occurred in those who took antidepressants (OR, 0.34; 95% CI, 0.12-0.94; P =.04) at the baseline examination. CONCLUSION Although many different medications were being used at the baseline examination in the Beaver Dam Eye Study cohort, there were no striking associations with the 5-year incidence of early ARM.

Abstract
OBJECTIVE To evaluate incident cataract after a 5-year interval with respect to medication use. DESIGN Population-based incidence study. MAIN OUTCOME Incident cataract judged from standard photographs. SETTING Study subjects were adults 43 to 86 years of age in 1988 to 1990 and again in 1993 to 1995. All participants were examined and interviewed, and photographs were taken. All procedures and grading were done by protocols at both examinations. All medications in current use, prescribed as well as over-the-counter, were brought to the examination site, and the names were recorded at that time. RESULTS There were 678 drug preparations (active ingredients) being used at the baseline examination. Significantly lower incidences of nuclear cataracts 5 years later occurred in those who took thiazide diuretics (odds ratio [OR] = 0.79, 95% confidence interval [CI] 0.63, 1.00) and aspirin (OR = 0.76, 95% CI 0.61, 0.95) at the baseline examination. There were significantly more incident cortical cataracts in those taking oral steroids (OR = 2.59, 95% CI 1.45, 4.62), amitriptyline (OR = 2.03, 95% CI 1.09, 3.79), oral hypoglycemic agents (OR 2.06, 95% CI 1.23, 3.44), and insulin (OR = 3.38, 95% CI 1.61, 7.08). There were significantly more incident posterior subcapsular cataracts in those taking potassium-sparing diuretics (OR = 2.13, 95% CI 1.42, 3.18) and oral hypoglycemic agents (OR = 2.89, 95% CI 1.57, 5.33). Considering past use with never and current use did not alter the patterns of associations. We were not able to separate the effects of antihypertensive or diuretic agents from that of hypertension. However, hypoglycemic agents were no longer associated with any cataract type after stratifying by diabetes status. CONCLUSIONS Although many different medications were being used at the baseline examination in the Beaver Dam Eye Study cohort, few were associated with incident cataract. However, with the high frequency of use of medications and the possibility that effects of current exposure may occur in the future, it is reasonable to follow this and other older cohorts for the development of cataract.

Abstract
The purpose of this investigation was to determine whether age-related cataract and maculopathy in older siblings predicts development of the same in younger siblings. A population-based study of age-related eye diseases was conducted in 1988--1990 in Beaver Dam, Wisconsin, and a follow-up examination was performed 5 years later. Diagnoses of age-related eye diseases were assigned on the basis of gradings of study photographs. There were 1,088 people from 488 sibships with at least two siblings who could contribute information for these analyses. The authors computed odds ratios and 95% confidence intervals for developing the specific lesion and identifying it 5 years later if an older sibling had it at baseline. The odds ratios were 1.65 (95% confidence interval (CI): 0.91, 2.99) for nuclear cataract, 1.62 (95% CI: 0.92, 2.85) for cortical cataract, 1.95 (95% CI: 0.48, 7.95) for posterior subcapsular cataract, 1.82 (95% CI: 0.91, 3.66) for soft drusen, 8.18 (95% CI: 3.34, 20.08) for retinal pigment epithelium depigmentation, 3.59 (95% CI: 1.71, 7.57) for increased retinal pigment, and 10.32 (95% CI: 0.83, 128.58) for exudative age-related maculopathy. These findings suggest that strong family determinants of lesions of age-related maculopathy are likely, less so for age-related cataract, which confer risk of the same lesion in a younger sibling.

Abstract
OBJECTIVE To investigate motor unit synchronization in the time and frequency domains and compare the amount and nature of this synchronization between upper and lower extremity muscles in human subjects. METHODS A total of 120 motor unit pairs from biceps brachii (BB), first dorsal interosseous (1DI), vastus medialis (VM), and tibialis anterior (TA) on the dominant side were analyzed and compared. Pairs of motor unit spike trains were recorded from two concentric needle electrodes inserted within these muscles in healthy volunteers. Subjects were instructed to maintain a weak isometric contraction of these muscles so that an individual motor unit recorded from each concentric needle discharged at a steady rate of approximately 10 impulses/s. Pairs of motor unit spike trains were cross-correlated in the time domain, and coherence analysis in the frequency domain was performed on the same spike train data. RESULTS Synchronization was seen in all the muscles studied. Strength of motor unit synchronization, expressed as synchronization index (SI), was greater in 1DI muscles compared to other muscles (P<0.01). Coherence analysis revealed significant association between motor unit firings in the 1--5 and 25--30 Hz frequency ranges in all the muscles studied. The incidence of 25--30 Hz coherence peaks were found to be greater for 1DI muscles compared to other muscles. CONCLUSION The above results suggest a possible role for corticospinal projections in producing pre-synaptic inputs responsible for synchronization of motor unit firings and 25--30 Hz coherence peaks.

Abstract
PURPOSE Brain metastasis is estimated to occur in 20~40% of solid tumor patients and the most common primary tumor is lung cancer. Even though the prognosis of brain metastasis is grave and the 1-year survival rate is only 15%, symptom palliations are made with whole brain radiation therapy. We retrospectively evaluated the clinical features and prognostic factors of lung cancer with brain metastasis. MATERIALS AND METHODS From January 1987 to October 1999, 50 lung cancer patients with brain metastasis underwent whole brain radiation therapy. We reviewed the improvement in neurologic symptoms and survival according to the following parameters; performance status, histological type, presence of brain metastasis at the initial diagnosis of lung cancer, presence of extracranial metastasis, multiplicity of brain lesion, presence of primary lung symptom and treatment modalities. RESULTS The most frequent symptom with brain metastasis was a headache (50%). Palliation of the headache and other symptoms was achieved in 81% of the patients. Median overall survival after brain metastasis was 21 weeks and the 1 year survival rate was 15%. Patients without extracranial metastasis had a longer median survival than those with, 38 weeks versus 15 weeks, respectively (p=0.01). CONCLUSION In lung cancer with brain metastasis, neurologic symptoms can be palliated with whole brain radiation therapy, and in this study among such patients, absence of extracranial metastasis can be a good prognostic factor.
