Abstract
OBJECTIVES New scientific knowledge is not always available to decision makers. Policy briefs are a way that dental researchers can communicate research findings to policymakers. This study compares usefulness of 2 types of policy briefs about sugar-sweetened beverage (SSB) intake and tooth decay. METHODS We developed 2 policy brief types (data focused and narrative focused) and emailed a randomly assigned policy brief to 825 policymakers and staff from 3 levels of government (city, county, and state) in Washington State. Participants completed a 22-item online questionnaire. There were 4 study outcomes: whether the brief was understandable, whether the brief was credible, likelihood of use, and likelihood to be shared (each measured on a 5-point Likert-like scale). The t test was used to evaluate whether outcomes differed by policy brief type and government level (α = 0.05). RESULTS There were 108 respondents (adjusted response rate 14.6%). About 41.6% of participants were in city government, 26.9% were in county government, and 29.6% were in state government. Participants reported that both data- and narrative-focused briefs were understandable (mean rating [MR] and standard deviation [SD]: 4.15 ± 0.68 and 4.09 ± 0.81, respectively; P = 0.65) and credible (MR and SD: 4.13 ± 0.70 and 4.09 ± 0.70, respectively; P = 0.74), but they were not likely to use (MR and SD: 2.71 ± 1.15 and 2.55 ± 1.28, respectively; P = 0.51) or share it (MR and SD: 2.62 ± 1.04 and 2.66 ± 1.30, respectively; P = 0.87). The likelihood of sharing briefs differed significantly by level of government (P = 0.017). Participants at the state level were more likely to share information from the briefs (mean rating and SD: 3.10 ± 0.80) than city- and county-level participants (MR and SD: 2.62 ± 1.27, and 2.24 ± 1.21, respectively). CONCLUSION Both data- and narrative-focused policy briefs may be a useful way to communicate dental research findings to policymakers, but additional steps are needed to ensure that briefs are used and shared. KNOWLEDGE TRANSFER STATEMENT Researchers should disseminate their research findings to maximize scientific impact. Our study findings indicate that policy briefs may be a useful way to communicate dental research findings to policymakers, but additional research is needed on the best ways to disseminate findings.

Abstract
BACKGROUND Information on the natural duration of carbapenem-resistant Enterobacteriaceae (CRE) carriage and factors associated with persistence of carriage is limited. AIM To evaluate the clinical variables associated with persistent carriage of Klebsiella pneumoniae carbapenemase (KPC)-producing CRE. METHODS Data for patients admitted between June 2015 and December 2016 who were identified as KPC-producing CRE carriers by either rectal swabs or clinical cultures were reviewed retrospectively. Patients with follow-up culture data for three months after initial acquisition were included. Regression models were used to evaluate the clinical variables associated with persistence of carriage. FINDINGS Of the 100 eligible patients, 50 patients (50%) experienced spontaneous decolonization within three months. Among the 50 patients (50%) who remained culture positive after three months, 26 patients carried KPC-producing CRE after six months. Multi-variable analysis revealed that re-admission [adjusted odds ratio (aOR) 9.96; 95% confidence interval (CI) 1.13-87.98; P=0.039], duration of hospitalization (aOR 1.03; 95% CI 1.01-1.05; P=0.003), positive clinical culture (aOR 6.26; 95% CI 1.28-30.54; P=0.023) and carbapenem use (OR 9.15; 95% CI 1.85-45.27; P=0.007) were predictive for persistent carriage after six months. CONCLUSION The results suggest that patients with KPC-producing CRE in clinical specimens who are using carbapenem, particularly those with multiple and prolonged hospitalizations, are more likely to remain carriers after six months of initial acquisition. This information is useful for coordinating strategies for pre-emptive isolation by predicting the CRE carriage status appropriately, and ensuring active surveillance through risk factor stratification.

Abstract
PURPOSE To assess efficacy or long-term result of metastasectomy for recurrent or metastatic biliary tract carcinoma (BTC), we conducted a retrospective review of the outcomes of metastasectomy for recurrent or metastatic BTCs, comprising intrahepatic cholangiocellular carcinoma (IHCCC), proximal and distal common bile duct cancer (pCBDC and dCBDC), gallbladder cancer (GBC), and ampulla of Vater cancer (AoVC). PATIENTS AND METHODS The clinicopathological features and outcomes of BTC patients who underwent surgical resection for the primary and metastatic disease at the Gachon University Gil Medical Centre from 2003 to 2013 were reviewed retrospectively. RESULTS We found 19 eligible patients. Primary sites were GBC (seven patients, 37%), IHCCC (five patients, 26%), dCBDC (three patients, 16%), pCBDC (two patients, 11%), and AoVC (two patients, 11%). Eight patients (42%) had synchronous metastasis whereas 11 (58%) had metachronous metastasis. The most common metastatic site was liver (nine patients, 47%), lymph node (nine patients, 47%), and peritoneum (three patients, 16%). Nine patients (47%) achieved R0 resection, whereas four (21%) and six (32%) patients had R1 and R2 resection, respectively. With a median follow-up period of 26.7 months, the estimated median overall survival (OS) was 18.2 months (95% confidence interval, 13.6-22.9 months). Lower Eastern Cooperative Oncology Group performance status (P = 0.023), metachronous metastasis (P = 0.04), absence of lymph node metastasis (P = 0.009), lower numbers of metastatic organs (P < 0.001), normal postoperative CA19-9 level (P = 0.034), and time from diagnosis to metastasectomy more than 1 year (P = 0.019) were identified as prognostic factors for a longer OS after metastasectomy. CONCLUSIONS For recurrent or metastatic BTCs, metastasectomy can be a viable option for selected patients.

Abstract
Southwestern China has an area with unique natural conditions located in alpine regions at altitudes from 2000 to 5000 m; this area is referred to as the Qinghai-Tibetan plateau (QTP). Unique animals, such as yaks (Bos grunniens), are found extensively on the plateau of Southwestern China due to its unique environment. In recent years, the prevalence of fake meat products such as fake jerky has increased in this area. This research was conducted as an attempt to develop a reliable multiplex polymerase chain reaction (mPCR) detection method for identifying nine animal species found in QTP. We developed the mPCR method using the specific sites found in 12S rRNA region of these nine species, which was effective in discriminating between the nine species and was successful in terms of validated reproducibility, detection limit (<6 pg total DNA), discrimination of mixed samples, and specificity (approximately 99%) using real meat samples. Our results show that the mPCR detection method can overcome the limitations of prior detection methods, such as restriction fragment length polymorphism or high-resolution melting analysis methods.

Abstract
The yak is primarily found throughout the Tibetan high plateau and the surrounding mountainous area of south central Asia; among its others attributes, its milk is very important for the local population. A key concern in the field of yak research is the better understanding of which genes control the production and composition of milk. The most accurate and sensitive method for gene expression analysis is quantitative reverse transcription polymerase chain reaction (RT-qPCR). It is essential for reliable RT-qPCR to be able to the normalize the data using internal control genes (ICGs). However, it is critical to assess the reliability of the normalization by testing multiple ICGs. Our objective was to uncover a reliable normalization for RT-qPCR data obtained from yak mammary tissue during the lactation cycle. We assessed the reliability of 10 ICGs (ACTB, EIF6, GAPDH, LRP10, MRPL39, MRPS15, MTG1, RPS8, RPS23, and UXT) using geNorm. The analysis revealed that all of the tested ICGs can be considered to be reliable, but the use of the 6 most stable ICGs should be applied to yield a reliable normalization factor (NF). We compared the results of 3 target genes (CSN1S1, ESR1, and MYC) normalized using 6, 3, or 1 of the best ICGs. We did not observe overall differences between the 3 normalization strategies with the exception of 1 time point in MYC. The use of only a single ICG is not recommended; thus, we concluded that the calculation of the NF using the 3 best ICGs, MRPS15, RPS23, and UXT, is a reliable normalization strategy for RT-qPCR data obtained from yak mammary tissue during pregnancy and lactation. A dilution effect of the ICGs due to a large increase in the mRNA of abundantly expressed genes in bovine and porcine mammary tissue during the lactation cycle was previously observed. To test for the presence of a dilution effect in our study, we evaluated the pattern of non-normalized RT-qPCR data of ICGs from pregnancy to lactation and compared them with the total RNA concentration, milk yield, and non-normalized RT-qPCR data of 3 target genes. With a few exceptions, the non- normalized RT-qPCR data for the tested ICGs was significantly increased by lactation and had a positive correlation with total RNA and the non-normalized RT-qPCR data of CSN1S1. These data clearly indicated the presence of a “concentration effect” of single mRNA that remains unexplained but needs to be accounted for during the normalization of RT-qPCR data. Based on our findings, we recommend that the NF of the MRPS15, RPS23, and UXT genes should be used in the normalization of RT-qPCR data obtained from mammary tissue of lactating yaks during pregnancy and lactation.

Abstract
BACKGROUND KRAS mutations are common and clearly contribute to malignant progression. The frequency of NRAS mutations and their relationship to clinical, pathologic, and molecular features remains unclear. METHODS We evaluated 130 colorectal tumors for mutations in KRAS and NRAS gene. We tested for mutations in codons 61 and 146 of KRAS and codons 12, 13, 59, 61 and 146 of NRAS. Mutation status was determined by targeted dideoxy sequencing. RESULTS Among the analyzed primary tumors, 36.2% had KRAS mutation. Of the 83 KRAS codon 12 and 13 wild-type patients, 7.2% had KRAS codon 61, 146 or NRAS. 40.7% harbored any RAS mutation. CONCLUSION The frequency of other RAS (NRAS and KRAS exon 3, 4) activating mutations in colorectal cancers is relatively low in Korean colorectal cancer patients.

Abstract
BACKGROUNDS/AIMS Gallbladder carcinoma is usually associated with an unfavorable prognosis, and the clinical outcome has not improved much. This study was conducted to evaluate outcomes with gallbladder carcinoma according to the type of surgery performed, and the prognostic factors for survival. METHODS One hundred and six patients with gallbladder carcinoma, who underwent surgery for the purpose of curative resection between January 1999 and June 2012 were reviewed retrospectively. RESULTS Out of 106 patients, curative resection was achieved in 75 (70.8%). The cumulative 1-, 2- and 5-year survival rates of the gallbladder carcinoma patients were 93.4%, 80.9% and 63.0%, respectively. Radical resections, including extended cholecystectomy, were more beneficial for long term survival of patients. The 5-year survival rate in patients who underwent curative resection (56.9%) was significantly higher than in those who underwent palliative resection (0%, p=0.000). Multivariate analysis revealed that curative resection, preoperative CA19-9, T-stage, N-stage and differentiation of histology were independently significant prognostic factors. CONCLUSIONS Curative resection and early detection of patients with gallbladder carcinoma were the most important factors for long term survival. Radical resection improves survival for patients with localized gallbladder carcinoma and can help to access exact prognosis and treatments.

Abstract
AIM We present the oncologic outcomes of laparoscopic nephroureterectomy management of pT3 upper urinary tract urothelial carcinoma. METHODS Between October 2003 and January 2011, 50 patients with pT3 upper urinary tract urothelial carcinoma which had pathologically confirmed underwent laparoscopic nephroureterectomy at our institution. Demographic data, perioperative results, pathological findings and oncologic outcomes were reviewed and analyzed retrospectively. RESULTS There were 36 patients (72%) of high grade lesion and 14 patients (28%) of low grade lesion. Lymphovascular invasion was observed in 16 patients (32%) and the surgical margin was positive in one patient. N stage was pN0 in 16 (32%), pN1 in 3 (6%), pN2 in 1 (2%) and pN3 in 1 (2%). The 5-year overall survival rate was 52.6% and the 5-year cancer-specific survival rate was 65.3%. Overall recurrence developed in 23 patients. There were 10 patients (20%) of urothelial recurrence which were all occurred in the bladder at the mean period of 13.6 months, and 7 patients of them were invasive bladder cancer. There were 16 patients (32%) of non-urothelial recurrence developed at the mean period of 9.69 months. On multivariate analyses lymphadenopathy and lymph node involvement of cancer (N+) were identified as independent predictive factors for the cancer-specific survival, and concomitant bladder tumor, grade and lymphovascular invasion were identified as independent predictive factors for the overall recurrence free survival. CONCLUSION Laparoscopic nephroureterectomy in patients with high stage upper urinary tract urothelial carcinoma appear comparable to those of open surgery in the regard of oncologic outcomes.

Abstract
The aim of this study was to compare human epidermal growth factor 2 (HER2) status in primary colorectal cancer and paired liver or lung metastasis. Gene amplification of HER2 has been intensively evaluated in contemporary oncology, especially in breast and stomach cancer. The knowledge of HER2 status in primary and metastatic sites may be of potential value for therapeutic decision making in metastatic colon cancer. The HER2 status was assessed by fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) in 94 colorectal cancer with corresponding liver or lung metastases. HER2 amplification was present in 19 of the 188 (10.1%) of both primary and metastases combined. Four (4.6%) patients showed HER2 amplification in the metastasis and 10 (10.6%) patients showed HER2 amplification in the primary tumor. In 14 cases (14.8%), the HER2 status of the primary lesions was different from that of the associated metastases. The presence of HER2 overexpression in KRAS mutant colon cancer was found in 5.3%. No relationship was found between HER2 expression and KRAS status (P = 0.486). The evidence of HER2 positive metastatic lesion and primary colorectal cancer suggest that HER2 assessment might be considered in selected cases when this may help change the therapeutic decision.

Abstract
Background The effect of insufficient node sampling in patients with rectal cancer managed by neoadjuvant chemoradiation followed by surgery has not been clearly determined. We evalulated the impact of insufficient sampling or even abscence of lymph nodes in the specimen on survival in patients at high-risk (T3, T4 or node positive) for rectal cancer. Methods We conducted a single institution, retrospective analysis of all patients who underwent surgical rectal resection following neoadjuvant chemoradiation for treatment of mid to lower rectal cancer between 1997 and 2009. ypNX was defined as the absence of lymph nodes retrieved in the resected specimen. Results A total of 132 patients underwent resection for treatment of rectal cancer following neoadjuvant chemoradiation. Ninety four patients (71.2%) were considered as having node-negative disease, including ypNx and ypN0. In 38 patients (28.8%), the primary tumor was associated with regional lymph node metastases (ypNpos). The mean number of retrieved nodes per specimen was 14.2, respectively. The five-year overall survival from initial operation for the ypNx group was 100%, respectively. The estimated five-year overall survival for ypN0 and ypNpos was 84.0% and 60.3%, respectively (P =0.001). No significant differences in overall survival were observed between the ypNx and ypN0 group (P =0.302). Conclusion Absence of recovered LN in resected specimens after neoadjuvant chemoradiation was observed in 7.6% of specimens. Absence of LN should not be regarded as a risk factor for poor survival or as a sign of less radical surgery.

Abstract
Backgrounds/Aims The diagnosis for cystic neoplasm of pancreas is based on the morphologic criteria through imaging studies, but the pre- and postoperative diagnoses are often inconsistent. This study aims at the analysis of clinical characteristics and the results of surgical treatments. Methods A retrospective review was performed on 93 patients who have undergone surgery for pancreatic cystic diseases in our hospital from January 2001 to February 2013. Among them, 69 patients were confirmed as cystic neoplasms based on pathologic findings. Their clinical manifestations, diagnostic accuracy, surgical method and complications, pathologic findings were analyzed. Results Serous cystic neoplasm was the most common (n=22), followed by mucinous cystic neoplasm (n=18), intraductal papillary mucinous tumor (n=11), solid pseudopapillary tumor (n=9), neuroendocrine tumor (n=7), and cystic lymphangioma (n=2). The most common clinical symptom is abdominal pains (49.3%). Preoperative imaging studies were consistent with pathological findings in 72% of patients. Cystic fluid CEA levels of 400 ng/ml or more were reliable to detect mucin secreting tumors. Pancreatoduodenectomy was performed for 13 cases and the remaining 54 patients were treated with left-side pancreatectomy. Malignancy was found in 9 cases (13%) of mucin secreting tumors; 5 cases (27.8%) in mucinous cystic neoplasm and 4 cases (36.4%) in intraductal papillary mucinous tumor. Two of these survived without recurrences during the follow-up periods. Conclusions Exact treatment protocols for cystic neoplasm of pancreas are not decided because tumors are found with atypical forms. Surgical management is suggested for resectable tumors because a good prognosis can be expected with proper surgery if precancerous lesions are suspected at the time of discovery.

Abstract
BACKGROUND/AIMS Recurrence after hepatic resection is one of the most important factors impacting the prognosis and survival of patients with hepatocellular carcinoma (HCC). We identified prognostic factors affecting overall survival (OS) and disease-free survival (DFS) in patients with HCC after hepatic resection. METHODS This study was of a retrospective cohort design, and 126 patients who underwent hepatic resection for HCC at Gachon University Gil Medical Center between January 2005 and December 2010 were enrolled. Various clinical, laboratory, and pathological data were evaluated to determine the prognostic factors affecting OS and DFS. RESULTS Two- and 4-year OS and 2- and 4-year DFS were 78.1% and 65% and 51.1% and 26.6%, respectively. In a multivariate analysis, preoperative α-fetoprotein (> 400 ng/mL), tumor size (≥ 5 cm), multiple tumors (two or more nodules), presence of portal vein invasion, modified Union for International Cancer Control (UICC) stage III/IV, and Barcelona Clinic Liver Cancer (BCLC) stage B/C were independent prognostic factors affecting a shorter OS. In the multivariate analysis, presence of microvascular invasion, modified UICC stage III/IV, and BCLC stage B/C were independent prognostic factors for a shorter DFS. CONCLUSIONS The presence of vascular invasion was an independent poor prognostic factor for OS and DFS in patients with HCC after hepatic resection. Thus, close postoperative surveillance for early detection of recurrence and additional treatments are urgently needed in patients with vascular invasion after hepatic resection.

Abstract
Backgrounds/Aims Choledochal cyst of the bile duct is characterized by cystic dilatation of the intra- or extrahepatic bile ducts. It is a relatively uncommon disease and there is still much controversy regarding its etiology as being congenital or acquired. Methods The medical records of 60 patients who underwent surgical treatments for choledochal cyst between April 1995 and April 2009 at the Gachon University Gil Hospital were reviewed retrospectively. To compare the clinical characteristics, patients under 19 years of age were grouped into children and the others were grouped into adults. Results Of the overall 60 patients, 24 were grouped into children and 36 were grouped into adults. Female predominance was common in both groups (M : F=1 : 6.5). The most common clinical symptom was abdominal pain (73.3%) in both groups. Children had remarkable jaundice (33.3% vs. 0%) and gastrointestinal symptoms including nausea and vomiting. Fever and chills were more common in children because of the associated complications of cholangitis. According to the Todani classification, type I was the most common form of choledochal cyst in both groups, and type IVa was significantly more common in children than adults (45.3% vs. 16.7%). Thirty patients (50%) had anomalous pancreaticobiliary ductal union which was confirmed by preoperative imaging studies or intraoperative cholangiography. All patients except for one child underwent cyst excision with hepaticojejunostomy. Conclusion There was no significant difference in the clinical characteristics of choledochal cysts between children and adults. However, combined diseases especially bile duct malignancy were common in aged patients, early detection and more aggressive surgery is necessary for patients with choledochal cysts.

Abstract
Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is the most common form of primary extranodal lymphomas. In most cases, it is developed as multifocal and mucosal lesions, and its initial diagnosis is made by biopsy of suspicious lesions on endoscopy. However, when gastric MALT lymphoma afflict submucosal site without typical mucosal lesion, further procedures are necessary for diagnosis, such as endoscopic mucosal resection and endoscopic ultrasonography. We recently experienced two cases of submucosal tumor-like gastric MALT lymphoma. Both cases were without any mucosal lesion. One case was confirmed by endoscopic mucosal resection, and the latter was by wedge resection. Treatment modalities included endoscopic mucosal resection, surgery, H. pylori eradication, and/or chemotherapy. Both cases achieved complete remission until our 18 months' and 16 months' follow up.

Abstract
BACKGROUND/AIMS It is difficult to clinically and endoscopically differentiate intestinal tuberculosis (ITB) and Crohns disease (CD). The aim of this study was to evaluate the usefulness of in vitro interferon-gamma (INF-gamma) assay for differential diagnosis between ITB and CD. METHODS Sixty patients for whom differential diagnosis between ITB and CD was difficult were enrolled between January 2007 and January 2009. The INF-gamma-producing T-cell response to early secreted antigenic target 6 and culture filtrate protein 10 were measured by T-SPOT.TB blood test in vitro. We evaluated the usefulness of T-SPOT.TB blood test by comparing its results with the final diagnosis. RESULTS Twenty and forty patients were revealed to be positive and negative in T-SPOT.TB blood test, respectively. Of the 20 patients found to be positive, 12 patients (60%) were finally diagnosed as ITB, 6 patients as CD, and 2 patients as Behcets enterocolitis. Of the 40 patients with negative results, 38 patients (95%) were diagnosed as CD; one as Behcets enterocolitis; one as nonspecific colitis; none as ITB. The sensitivity and specificity of T-SPOT.TB blood test for ITB were 100% and 83.3%, respectively. Positive and negative predictive values of T-SPOT.TB blood test for ITB were 60.0% and 100%, respectively. CONCLUSIONS When differential diagnosis between ITB and CD is difficult, T-SPOT.TB blood test may be a helpful and rapid diagnostic tool to exclude ITB. Prospective large-scaled studies are required for further evaluation of the usefulness of T-SPOT.TB blood test for differential diagnosis between ITB and CD.

Abstract
BACKGROUND/AIM The purpose of this study was to investigate clinically useful information for effective screening for synchronous and metachronous second primary cancers and to suggest potential surveillance tool. METHODS We retrospectively reviewed 1,063 patients who were treated with potentially curative surgery for colorectal cancer at Gachon University, Gil Hospital from 1997 to 2007. RESULTS The incidence of synchronous or metachronous cancer in addition to colorectal cancer was 5.3% (57 patients). The most common second primary cancer was stomach (54.3%), followed by cancers in cervix (12.2%). The time interval between the first and second tumor in colorectal cancer associated with metachronous extracolonic malignancy ranged from 1.1 to 10.8 years. The incidence of early-stage tumor was higher in patients with synchronous cancer than in those with a metachronous cancer with statistical significance (p = 0.034). The 5-year survival rate of the colorectal cancer group without second primary cancer was 70.1%, whereas that for the second primary cancer group was 63.8% (p = 0.253). The 5-year survival rate of the colorectal cancer group with stomach cancer was 70.5%, whereas that for the second primary cancer other than stomach cancer group was 56.6% (p = 0.282). CONCLUSION The frequent association between colorectal cancer and gastric cancer suggests an inclusion of gastrofiberscope when surveillancing patients with colorectal cancer in Korean population. Second primary cancers may develop even 10 years after the initial operation; thus, a need for lifelong surveillance even more than 5 years may be necessary.

Abstract
PURPOSE Intrabdominal actinomycosis is difficult to diagnose preoperatively. This chronic infection has a propensity to mimic many other diseases and may present with a wide variety of symptoms. The aim of this study was to evaluate the characteristic clinical features with review of the literature. MATERIALS AND METHODS We retrospectively analyzed 22 patients with intrabdominal actinomycosis between January 2000 and January 2006. RESULTS There were two men and 20 women with a mean age of 42.8 years (range, 24-69). Twelve patients presented with masses or abdominal pain, whereas 3 patients presented with acute appendicitis. The rate of performing an emergency surgery was 50% due to symptoms of peritonitis. The mean size of tumor was 5.5 cm (range, 2.5-11.0). Sixty percent (n = 12) of female patients had intrauterine device (IUD). The average time to definite diagnosis was 10.6 days. CONCLUSION Intrabdominal abdominal actinomycosis must first be suspected in any women with a history of current or recent IUD use who presents abdominal pain. If recognized preoperatively, a limited surgical procedure, may spare the patient from an extensive operation.

Abstract
Background Multiple sclerosis (MS) patients experience fatigue as a chronic symptom that decreases quality of life. Commonly, fatigue in MS patients is manifested as decreased motor function during or after physical activity and is associated with changes in brain metabolism. Objective To determine brain activation patterns in MS patients and healthy controls during a simple motor task before and after fatiguing hand-grip exercise. Methods Functional magnetic resonance imaging (fMRI) scans were conducted on 10 MS patients and 13 healthy controls during 4-finger flexion and extension in rested and fatigued states. Results Before the fatigue protocol, MS patients had greater activation in the contralateral primary motor cortex, insula, and cingulate gyrus than controls. Following fatiguing exercise, controls showed increased activation of precentral gyrus and insula while patients did not show any activation increases and actually decreased activity to the insula. Conclusion Results indicate that before fatiguing exercise, MS patients marshaled more brain activation compared to controls, which may represent functionally adaptive changes in response to demyelination. This increased activation may suggest that patients require more effort to perform even simple motor tasks, possibly because peripheral or central signals for fatigue are chronically enhanced. When fatigued further by muscle contraction, brain activation cannot be further increased.

Abstract
In recent years, non-tuberculous mycobacteria (NTM) have emerged as an important cause of opportunistic nosocomial infections but there is little known about the isolation and identification of NTM in Korea. The aim of this study was to assess the prevalence of NTM in the hospital environment and identify the species. A total of 150 samples were collected from different parts of the hospital. NTM were isolated and identified by restriction fragment length polymorphism analysis of the gene encoding rpoB and partial sequencing analysis of hsp65 and rpoB. In this study, 60 strains of NTM were isolated from 50 of the 150 samples. Half of the tap water samples (50 of 100) were positive for mycobacteria. An estimated 73.3% of the isolates were saprophytic, 21.7% were potentially pathogenic and 5% were unidentified. The presence of NTM in hospital tap water is not uncommon. Such water isolates might cause true nosocomial infection in immunocompromised patients, in addition to the risk of false-positive culture results.

Abstract
BACKGROUND The aim of the study was to test whether the COMT, CYP1A1 and CYP17 genes influence the risk of developing adenomyosis and endometriosis. METHODS We conducted two case-control studies, where the cases (n = 198) had either of the two diseases, and controls (n = 312) were disease-free women. For the COMT gene, we selected the G/A nonsynonymous single-nucleotide polymorphism (SNP) that leads to valine-to-methionine (Val/Met) substitution. For the CYP1A1 gene, we used a functional T/C SNP in the 3'-noncoding region, and we genotyped a T/C functional SNP in the 5' region of the CYP17 gene for the present study. Hardy-Weinberg equilibrium was checked in both cases and controls. Logistic regression models were used to evaluate the genetic effect, with adjustment for other covariates. RESULTS We found that the homozygous COMT genotype that encodes low enzyme activity had an increased risk for adenomyosis with an age-adjusted odds ratio of 3.2 (95% confidence interval 1.3-7.8; P = 0.006). The COMT gene, however, was not associated with endometriosis. Neither the CYP1A1 nor CYP17 genes had any significant association with either of the two diseases. CONCLUSION The COMT gene significantly influences the risk of adenomyosis but not endometriosis. The present study does not provide evidence to support any of the three genes exerting pleiotropic effects on both diseases.

Abstract
UNLABELLED Living donors have always been the basic resources of transplantation in our country, where cadaveric harvesting is still hampered for various reasons. OBJECTIVE The aim of this study was to compare graft survival rates between living unrelated donor (LURD) and living related donor (LRD), to assess the potential risk factors for the graft survival, and to discuss the role of LURD. METHOD From October 1991 to February 2003, 77 living donor renal transplants were performed: 41 were LURD and 36 were LRD transplants. The analyzed variables were donor relationship, recipient age and sex, donor age and sex, HLA-DR mismatching, nonspecific blood transfusion history of donor, acute rejection episodes, repeated rejection episode (more than 3 times), delayed graft function, recurred primary disease, and immunosuppressive regimen. Graft survival rate was assessed with the Kaplan-Meier method and the significance of possible variables with the Cox proportional hazard model. RESULTS Eleven recipients lost their grafts (6 from LURD and 5 from LRD), most of them are due to chronic rejection (n = 7). Overall 3-, 5- and 10-year graft survival in live donors were 92.8%, 86.6%, and 76.9%, respectively. Graft survival at 3, 5, and 10 years being 91.9%, 88.5%, and 74.7% for the LURD versus 94%, 84%, and 78.8% for LRD transplants (P > .05). Acute rejection episodes, especially more than 3 times (risk ratio [RR] = 11.1) and preoperative multiple transfusion history (RR = 4.2) were significant factors on graft survival in our series. CONCLUSION Acute rejection episodes markedly decreased the long-term graft survival in live donor renal transplants. The use of LURD transplants provides graft survival comparable with LRD transplants and proper management to acute rejection is essential for long-term graft survival.

Abstract
UNLABELLED Any attempt to improve organ donation would be of benefit due to the growing shortage of cadaveric sources for transplantation. OBJECTIVE We compared the graft survivals and possible predictive variables among renal transplant recipients with organs from living unrelated (LURD) versus cadaveric donors (CD). METHOD Among 104 consecutive renal transplants performed from July 1992 to February 2003, 41 were from LURD and 24 from CD. Immunosuppressive regimens were based on cyclosporine and steroids with mycophenolate mofetil added after 1998. Patient and graft survivals were estimated using the Kaplan-Meier method and compared using log-rank tests. The significance level of predictive variables was analyzed with the Cox proportional hazard model. The follow-up period was 2 to 127 months (median 46 months). RESULTS Eight recipients lost their grafts (six from LURD and two from CD) due to four chronic rejections, one acute rejection, one recurrence of primary disease, and one death with a functioning graft. The graft survival rates at 1, 3, 5, and 7 years were 97.6%, 91.9%, 88.5%, and 82.2% for LURD transplants versus 95.5%, 90.9%, 90.9%, and 90.9% for CD transplants, respectively (P > .05). Delayed graft function and donor age (>55 years old) were statistically significant predictors of graft survival among LURD transplants. Donor age (>55 years old) and multiple preoperative transfusion history were significant in CD transplants. CONCLUSION LURD transplant survival was similar to that of CD transplants in our series. LURDs are an excellent source of organs to expand the donor pool.

Abstract
We report our experience evaluating tasks designed to visualize regions of motor and language brain activation using functional magnetic resonant imaging (fMRI). Our goal was to identify a battery of tasks which would provide a range of brain imaging studies which could be used clinically for surgical planning, with the requirement that they could be performed and analyzed rapidly, thus, cost effectively. These tasks were chosen to assess (1) motor control of the hands, fingers, and feet, and (2) language processing using both auditory and visual task presentations. From January through April 2001, five patients and eight normal subjects were studied. A selection of three or four tasks acquired with an EPI sequence coupled with a high resolution 3D MR sequence were completed in 45- 60 min of scanner time. Identification of the location of eloquent cortex serving aspects of motor and language functions was successful in four of the five patients and all of the eight normal subjects.

Abstract
OBJECTIVE The aim of this prospective 3-year clinical study was to examine the effect of hormone replacement therapy (HRT) on uterine fibroid growth among postmenopausal women. METHODS Thirty-seven postmenopausal women with uterine solitary fibroids were recruited randomly for HRT in a 3-year program. All participants received 0.625 mg conjugated equine estrogen (CEE) and 5 mg medroxyprogesterone (MPA) daily. Fibroid volume was measured by transvaginal ultrasonography at baseline and then at 12-month intervals for 3 times. Clinically, significant fibroid growth was defined as an increase in volume of more than 25% compared with baseline. Also, 35 postmenopausal women with uterine fibroid were studied as control who did not receive HRT during the study period. RESULTS Fibroid volume had increased significantly after 1 year both in HRT users and non-users. These increases continued to the second year significantly in HRT users but not in non-users. However, the volumes declined significantly at the third year to similar levels as those measured at baseline in control. In HRT users, fibroid volume though significantly increased at the third year (vs. baseline) but declined insignificantly in comparison with the second year. Clinically, at end of the third year study, one of 34 and three of 34 women increased fibroid volume over 25% compared with baseline in HRT non-users and users, respectively. CONCLUSIONS HRT does increase uterine fibroid volume statistically. However, its effect appears in the first 2 years of use. The increased fibroid volume begins to decline at the third year both in HRT users and non-users. Clinically, the increased effect of HRT on uterine fibroid of postmenopausal women should be not over-emphasized at least for 3 years of usage.

Abstract
It has been a common belief that estrogen regulates cellular responses through binding to its receptor, the estrogen receptor (ER). In the nucleus, estrogen modulates the expression of estrogen-responsive genes through the action of the ER at the transcriptional level. In the cytoplasm, the ER-dependent signaling pathway has been shown to be involved in the activation of Akt and the downstream molecules. It is not clear, however, whether estrogen can modulate cytoplasmic signaling in an ER-independent manner. Human breast cancer cell lines without detectable ERs such as MDA-MB-435 and MDA-MB-231 were treated in estrogen-depleted medium followed by a brief treatment with estrogen. The activation of Akt was evaluated by a phosphoserine antibody. Our results showed that estrogen stimulated Akt activation, as indicated by phosphorylation at Ser(473) of the oncoprotein, in ER-negative breast cancer cells. Activation of Akt by estrogen in these cells was time and dose dependent and could be blocked by inhibitors of phosphatidylinositol 3'-kinase and Src kinase but not by estrogen antagonists. Our results provide evidence as well as the mechanism of the receptor-independent function of estrogen, in which the antiapoptotic factor Akt is activated.

Abstract
Elevated tumor markers for a post-menopausal woman presenting with a multilocular adnexal mass, ascites, and pleural effusion were interpreted as being highly suspicious of malignancy. This paper describes two cases of ovarian tumors presenting with all signs of malignancy. Following surgical excision of the masses, and histopathological assay, a benign pure struma ovarii and a mucinous cystadenoma were diagnosed by pathologists. The immediate and complete resolution of symptoms were achieved post-operatively, and the previously-evident abnormal tumor markers rapidly declined to the normal range, the two tumors were subsequently classified as pseudo-Meigs' syndromes.

Abstract
A person's ability to cope with having motor neurone disease may be an important factor in determining their quality of life. We have developed a scale to measure coping strategies in people with MND. A disease-specific and patient-focused approach was employed. Open-ended interviews were used to generate initial items. Coping with the condition was an important consideration for all subjects. The final scale was administered to a sample of 44 people with MND. A factor analysis of the results demonstrated subscales comprised of distinct styles of coping. Reliability and validity were demonstrated within individual subscales. Significant correlations were shown between coping styles and psychological well being, disease duration and disability. Although still at a preliminary stage of development, the MND Coping Scale is proposed as a useful tool for further longitudinal study of coping in MND, with the potential to discover cause effect relationships between coping and psychological outcome.

Abstract
To address a fundamental need in stable isotope metrology, the National Institute of Standards and Technology (NIST) has established a web-based interactive data-processing system accessible through a common gateway interface (CGI) program on the internet site http://www. nist.gov/widps-co2. This is the first application of a web-based tool that improves the measurement traceability afforded by a series of NIST standard materials. Specifically, this tool promotes the proper usage of isotope reference materials (RMs) and improves the quality of reported data from extensive measurement networks. Through the International Atomic Energy Agency (IAEA), we have defined standard procedures for stable isotope measurement and data-processing, and have determined and applied consistent reference values for selected NIST and IAEA isotope RMs. Measurement data of samples and RMs are entered into specified fields on the web-based form. These data are submitted through the CGI program on a NIST Web server, where appropriate calculations are performed and results returned to the client. Several international laboratories have independently verified the accuracy of the procedures and algorithm for measurements of naturally occurring carbon-13 and oxygen-18 abundances and slightly enriched compositions up to approximately 150% relative to natural abundances. To conserve the use of the NIST RMs, users may determine value assignments for a secondary standard to be used in routine analysis. Users may also wish to validate proprietary algorithms embedded in their laboratory instrumentation, or specify the values of fundamental variables that are usually fixed in reduction algorithms to see the effect on the calculations. The results returned from the web-based tool are limited in quality only by the measurements themselves, and further value may be realized through the normalization function. When combined with stringent measurement protocols, two- to threefold improvements have been realized in the reproducibility of carbon-13 and oxygen-18 determinations across laboratories.

Abstract
This preliminary study was carried out over 18 months to evaluate whether the side effects in patients with advanced ovarian cancer receiving chemotherapy using paclitaxel-carboplatin differed between weekly (98 cycles in 14 patients) and monthly (102 cycles in 15 patients) administrations. We used paclitaxel (60 mg/m2) and carboplatin (AUC of 2) in the weekly regimen and 175 mg/m2 of paclitaxel and carboplatin (AUC of 6) in the monthly regimen. All eligible patients received at least four cycles of treatment in both regimens. The results revealed significantly decreased hematological toxicity in weekly regimens relative to monthly ones, ie, 7.1% vs. 18.6% of anemia (> or = grade 2), 7.1% vs. 32.3% of grade 3/4 granulocytopenia, and 0% vs. 15.7% of >grade 2 thrombocytopenia. There was no significant difference in nonhematological toxicities between the two regimens. The incidence of unscheduled events was much less in the weekly regimen than in the monthly one; ie, delayed treatment (3 vs. 18 events), unanticipated hospitalizations (3 vs. 15 times), and supplemental support with G-CSF (7 vs. 33 times). Complete responses were observed in 6 of 14 patients in the weekly regimen and in five of 15 patients in the monthly regimen, while partial responses were seen in four and five patients in the weekly and monthly regimens, respectively. The present results demonstrate that the weekly regimen can achieve the benefits of tolerable toxicity with significantly reduced myelosuppression and improved cost-effectiveness in terms of unscheduled events.

Abstract
The 7-dehydrocholesterol reductase (Dhcr7) is the terminal enzyme in the pathway of cholesterol biosynthesis. We have previously reported that sterol depletion in vivo caused a significant induction of both liver mRNA and enzyme activity of Dhcr7 (Bae, S.-H., Lee, J. N., Fitzky, B. U., Seong, J., and Paik, Y.-K. (1999) J. Biol. Chem. 274, 14624-14631). In this paper, we also observed liver cell-specific sterol-mediated Dhcr7 gene induction in vitro by sterol depletion in rat hepatoma cells, suggesting the presence of sterol-mediated regulatory elements in the Dhcr7 gene. To understand the mechanisms responsible for regulating Dhcr7 expression, we have isolated the 5'-flanking region of the gene encoding rat Dhcr7 and have characterized the potential regulatory elements of the gene that are responsible for sterol-mediated regulation. The Dhcr7 promoter contains binding sites for Sp1 (at -177, -172, -125, and -20), NF-Y (at -88 and -51), and SREBP-1 or ADD1 (at -33). Deletion analysis of the Dhcr7 gene promoter (-1053/+31), employing a nested series of Dhcr7-luciferase constructs, demonstrated that the -179 upstream region of the gene is necessary and sufficient for optimal efficient sterol-regulated transcription. DNase I footprinting and electrophoretic mobility shift assay showed that the SRE1/E box (-33/-22) involved in sterol response of many sterol-related enzyme genes was protected specifically by the overexpressed recombinant ADD1. Mutational analysis for the functional relationship between the identified cis-elements in this region indicate that one of the binding sites for Sp1 (GC box at -125) and NF-Y (CCAAT box at -88) plays a cooperative role in the sterol-mediated activation, in which the latter site also acts as a co-regulator for SREBP-activated Dhcr7 promoter activity. We believe that Dhcr7 is the first enzyme characterized with a sterol-regulatory function in the post-lanosterol pathway. This may be important for understanding the coordinated control of cholesterol biosynthesis as well as the molecular mechanism of Smith-Lemli-Opitz syndrome-related protein in mammals.
