Abstract
BACKGROUND Healthcare workers (HCWs) have an increased risk of blood-borne pathogen (BBP) infection due to occupational blood exposures (OBEs). Early reporting, detection, and post-exposure prophylaxis (PEP) allows for prevention of infections. AIM To investigate the incidence of OBEs, related epidemiological characteristics, PEP completion rate, time and reason for PEP discontinuation, and seroconversion rate reported over 10 years. METHODS We retrospectively analysed 1,086 OBE cases and staff PEP management from January 2012 to December 2021 in a South Korean tertiary hospital. FINDINGS The mean incidence of OBE was 7.82 per 100 beds and 3.0 per 100 HCWs. Among 1,086 cases, 633 (58.3%) required PEP, and 453 (41.7%) did not. After OBEs, 70.1% (444/633) of those subject to PEP completed tracking, and 29.9% (189/633) stopped PEP tracking (p < 0.001). The PEP completion rate showed a significant difference according to gender (p = 0.024), occupation (p < 0.001), and exposure frequency (p < 0.001). None of the 444 HCWs who completed PEP seroconverted to hepatitis B virus, hepatitis C virus, human immunodeficiency virus, or Treponema pallidum (syphilis). CONCLUSION Our findings demonstrate the need to improve follow-up care among HCWs following OBEs. There is a need for education in healthcare facilities; moreover, establishing a national surveillance system is necessary to ensure that HCWs proactively undergo PEP and complete their follow-up visits.

Abstract
BACKGROUND The global increase in the prevalence of vancomycin-resistant enterococci (VRE) and carbapenem-resistant Enterobacterales (CRE) among multidrug-resistant organisms (MDROs) has necessitated contact precaution and isolation in medical institutions. Contact isolation has a negative effect on the mental health of patients, but few interventions have addressed this issue. AIM This study evaluated an isolation-coping programme developed for patients colonized or infected with VRE or CRE. METHODS To mitigate the negative effects of isolation due to having MDRO, an infection control nurse in the present study 1) developed an isolation-coping programme and 2) validated the programme's effect on the uncertainty, anxiety, depression, and knowledge of patients isolated because of MDRO (VRE or CRE) using a pre-post quasi-experimental design. FINDINGS The experimental group (n=56) received education and emotional support via the isolation-coping programme, while the control group (n=55) received only verbal isolation guidelines provided by the medical institution. Compared with the control group, the experimental group showed a reduction in uncertainty (t=-8.925), anxiety (Z=-6.131), and depression (Z=-5.379), and better knowledge (Z=-8.372) (p<.001 for all). CONCLUSION The novel isolation-coping programme is an effective intervention to improve uncertainty, anxiety, depression, and knowledge in patients isolated with VRE or CRE.

Abstract
Background Complex regional pain syndrome (CRPS) is a rare but feared complication in hand surgery. Although multimodal therapy concepts are recommended, there is only low evidence on efficacy of such approaches. Furthermore, recommendations regarding therapy duration are lacking. Aim of this study was to validate the efficacy of an International Classification of Functioning, Disability and Health (ICF)-based multidisciplinary rehabilitation concept for treatment of CRPS of the hand and to find correlations between therapy duration and outcome measures. Methods Patients with CRPS of the hand after occupational trauma that underwent an ICF-based rehabilitation program between 2010 and 2014 were included in this retrospective study. Besides demographic data, outcomes included pain (VAS), range of motion assessed by fingertip-to-palm-distance (PTPD) and fingernail-to-table-distance (FTTD) as well as strength in grip, 3-point pinch and lateral pinch. All measures were gathered at admission to and discharge from inpatient rehabilitation therapy as well as at follow-up. Statistical analysis included paired t-test, ANOVA and Pearson's correlation analysis. Results Eighty-nine patients with a mean age of 45 years were included in this study. Duration of rehabilitation therapy was 53 days on average. All outcomes improved significantly during rehabilitation therapy. Pain decreased from 6.4 to 2.2. PTPD of digit 2 to 5 improved from 2.5, 2.8, 2.6, and 2.3 cm to 1.3, 1.4, 1.2, and 1.1 cm, respectively. FTTD of digit 2 to 5 decreased from 1.5, 1.7, 1.5, and 1.6 cm to 0.6, 0.8, 0.7, and 0.7 cm, respectively. Strength ameliorated from 9.5, 3.7, 2.7 kg to 17.9, 5.6, 5.0 kg in grip, lateral pinch, and 3-point pinch, respectively. Improvement in range of motion significantly correlated with therapy duration. 54% of patients participated at follow-up after a mean of 7.5 months. Outcome measures at follow-up remained stable compared to discharge values without significant differences. Conclusion The ICF-based rehabilitation concept is a reliable and durable treatment option for CRPS of the hand. Range of motion improved continuously with therapy duration and thus may serve as an indicator for optimum length of therapy.

Abstract
BACKGROUND Carbapenemase-producing Enterobacteriaceae (CPE) can lead to life-threatening outcomes with rapid spread of the carbapenemase gene in solid organ transplantation (SOT) recipients because of limitations of available antibiotics. We examined the characteristics and importance of CPE acquisition in SOT recipients with large numbers of CPE isolates. METHODS Between November 2015 and October 2016, 584 CPE isolates were found in 37 recipients and verified by carbapenemase gene multiplex polymerase chain reaction (PCR). One hundred recipients with at least 2 negative results in carbapenemase PCR for stool surveillance and no CPE isolates in clinical samples were retrospectively included. RESULTS Most CPE isolates were Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (546, 93.5%). The most frequent transplantation organ was lung (43.3%), and the most common sample with CPE isolates other than stool was respiratory tract (22.6%). The median time between SOT and first CPE acquisition was 7 days. All-cause mortality was significantly higher in recipients with CPE than in those without CPE (24.3% vs 10.0%; P = .03). In multivariate regression analysis, stool colonization of vancomycin-resistant Enterococci and/or Clostridium difficile during 30 days before SOT (odds ratio [OR], 3.28; 95% CI, 1.24-8.68; P = .02), lung transplantation (OR, 4.50; 95% CI, 1.19-17.03; P = .03), and intensive care unit stay ≥2 weeks (OR, 6.21; 95% CI, 1.72-22.45; P = .005) were associated with acquisition of CPE. CONCLUSIONS Early posttransplantation CPE acquisition may affect the clinical outcome of SOT recipients. Careful screening for CPE during the early posttransplantation period would be meaningful in recipients with risk factors.

Abstract
BACKGROUND Poor oral health is associated with a reduced quality of life and serious illnesses. Consequently, nurses need to be more aware of oral health to improve the general health of residents in care. AIM To evaluate and compare oral health behaviours and levels of salivary haemoglobin and dental biofilm acidogenicity, which can be used to evaluate oral disease activity, between residents and community dwellers in South Korea. METHODS This cross-sectional study included 133 participants: 64 residents and 69 community dwellers. All participants completed a questionnaire and tests to measure their salivary haemoglobin and dental biofilm acidogenicity. RESULTS A higher percentage of community dwellers than of residents brushed their teeth three times a day, cleaned their tongue, used interdental cleaning devices and had visited a dental clinic within 1 year. The levels of salivary haemoglobin and dental biofilm acidogenicity tended to be higher in residents than in community dwellers. CONCLUSION Residents showed poorer oral health behaviours and higher levels of gingival bleeding and acid production by oral bacteria than did community dwellers. IMPLICATIONS FOR NURSING PRACTICE Nursing staff should enhance their monitoring of oral hygiene status and provide quality oral care to residents through cooperation with dental professionals. IMPLICATIONS FOR NURSING AND HEALTH POLICY Policymakers should be aware that oral health is an essential component of improving general health and well-being and therefore strive to develop policies to promote oral care services provided to residents. Nursing policies, such as mandating oral care and hands-on training in oral care for nursing staff, are important. We also suggest that factors related to oral care be added to the establishment or accreditation standards of care facilities.

Abstract
Phytochemical investigation of Lycopodium complanatum whole plants led to the isolation of two new serratene-type triterpenoids (1 and 2) along with eight known triterpenoids (3-10). Their structures were established using 1D and 2D NMR spectroscopic techniques and mass spectrometry. These compounds did not inhibit acetylcholinesterases (AChE) and butyrylcholinesterase (BChE), but did inhibit β-secretase 1 (BACE1). Compounds 1 and 6 showed potent BACE1 inhibition with IC50 values of 2.79 ± 0.28 and 2.49 ± 0.12 μM, respectively. The kinetic study of BACE1 inhibition revealed that compound 1 showed competitive inhibition, whereas 6 showed mixed-type inhibition. Furthermore, molecular docking results showed that the tested inhibitors 1 and 6 exhibited good binding affinities toward BACE1, with binding energies of -8.8 and -10.3 kcal/mol, respectively.

Five new compounds, 10-oxomornigrol F (1), (7″R)-(-)-6-(7″-hydroxy-3″,8″-dimethyl-2″,8″-octadien-1″-yl)apigenin (2), ramumorin A (3), ramumorin B (4), and (4S,7S,8R)-trihydroxyoctadeca-5Z-enoic acid (5), together with 31 known compounds (6-36), were isolated from the twigs of Morus alba (Moraceae). The chemical structures of these compounds were established using spectroscopic analyses, 1D and 2D NMR, high-resolution electrospray ionization mass spectrometry (HRESIMS), and Mosher's methods. The anti-inflammatory activities of the compounds were evaluated by investigating their ability to inhibit lipopolysaccharide (LPS)-induced nitric oxide (NO) production in macrophage RAW 264.7 cells. Compounds 1, 2, 13, 17, 19, 25-28, and 32 showed inhibitory effects with IC50 values ranging from 2.2 to 5.3μg/mL. Compounds 1, 2, 17, 25, and 32 reduced LPS-induced inducible nitric oxide synthase (iNOS) expression in a concentration-dependent manner. In addition, pretreating the cells with compound 1, 17, and 32 significantly suppressed LPS-induced expression of cyclooxygenase-2 (COX-2) protein.

Abstract
In the present study, ten alkaloids, namely chabamide (1), pellitorine (2), retrofractamide A (3), pyrroperine (4), isopiperolein B (5), piperamide C9:1 (8E) (6), 6,7-dehydrobrachyamide B (7), 4,5-dihydropiperine (8), dehydropipernonaline (9), and piperine (10), were isolated from the fruits of Piper nigrum. Among these, chabamide (1), pellitorine (2), retrofractamide A (3), isopiperolein B (5), and 6,7-dehydrobrachyamide B (7) exhibited significant inhibitory activity on lipopolysaccharide-induced nitric oxide (NO) production in RAW264.7 cells, with IC50 values of 6.8, 14.5, 30.2, 23.7, and 38.5 μM, respectively. Furthermore, compound 1 inhibited lipopolysaccharide-induced NO production in bone marrow-derived macrophages with IC50 value of 9.5 μM. Consistent with NO inhibition, treatment of RAW264.7 cells with chabamide (1), pellitorine (2), and 6,7-dehydrobrachyamide B (7) suppressed expression of inducible NO synthase and cyclooxygenase-2. Chabamide (1), pellitorine (2), and 6,7-dehydrobrachyamide B (7) induced heme-oxygenase-1 expression at the transcriptional level. In addition, compound 1 induced the nuclear translocation of nuclear factor-E2-related factor 2 (Nrf2) and upregulated the expression of Nrf2 target genes, NAD(P)H:quinone oxidoreductase 1 and γ-glutamyl cysteine synthetase catalytic subunit, in a concentration-dependent manner in RAW264.7 cells. These findings suggest that chabamide (1) from P. nigrum exert antiinflammatory effects via the activation of the Nrf2/heme-oxygenase-1 pathway; hence, it might be a promising candidate for the treatment of inflammatory diseases.

Abstract
Radiation treatment often leads to irreversible damage to normal salivary glands (SGs) because of their proximity to head and neck cancers. Optimization of the in vitro model of irradiation (IR)-induced SG damage is warranted to investigate pathophysiology and monitor treatment outcome. Here, we present an organotypic spheroid culture model to investigate the impact of IR on SGs and the mechanisms underlying IR-induced structural and functional changes. Human parotid epithelial cells were obtained from human parotid glands and plated on either plastic plates or Matrigel. A number of 3-dimensional (3D) spheroids were assembled on Matrigel. After IR at 10 and 20 Gy, morphologic changes in cells in 2D monolayers and 3D spheroids were observed. As the structural integrity of the 3D spheroids was destroyed by IR, the expression levels of salivary epithelial and structural proteins and genes decreased proportionally with radiation dosage. Furthermore, the spheroid culture allowed better measurement of functional alterations following IR relative to the monolayer culture, in which IR-inflicted spheroids exhibited a loss of acinar-specific cellular functions that enable Ca2+ influx or secretion of α-amylase in response to cholinergic or β-adrenergic agonists. p53-mediated apoptotic cell death was observed under both culture conditions, and its downstream signals increased, such as p53 upregulated modulator of apoptosis (PUMA), Bax, cytochrome c, caspase 9, and caspase 3. These results suggest that the organotypic spheroid culture could provide a useful alternative model for exploration of radiobiology and mode of action of new therapies for prevention of radiation-induced salivary hypofunction.

Abstract
This study was conducted to determine the relationships of five intragenic single nucleotide polymorphism (SNP) markers (protein kinase adenosine monophosphate-activated γ3 subunit [PRKAG3], fatty acid synthase [FASN], calpastatin [CAST], high mobility group AT-hook 1 [HMGA1], and melanocortin-4 receptor [MC4R]) and meat quality traits of Duroc breeding stocks in Korea. A total of 200 purebred Duroc gilts from 8 sires and 40 dams at 4 pig breeding farms from 2010 to 2011 reaching market weight (110 kg) were slaughtered and their carcasses were chilled overnight. Longissimus dorsi muscles were removed from the carcass after 24 h of slaughter and used to determine pork properties including carcass weight, backfat thickness, moisture, intramuscular fat, pH24h, shear force, redness, texture, and fatty acid composition. The PRKAG3, FASN, CAST, and MC4R gene SNPs were significantly associated with the meat quality traits (p<0.003). The meats of PRKAG3 (A 0.024/G 0.976) AA genotype had higher pH, redness and texture than those from PRKAG3 GG genotype. Meats of FASN (C 0.301/A 0.699) AA genotype had higher backfat thickness, texture, stearic acid, oleic acid and polyunsaturated fatty acid than FASN CC genotype. While the carcasses of CAST (A 0.373/G 0.627) AA genotype had thicker backfat, and lower shear force, palmitoleic acid and oleic acid content, they had higher stearic acid content than those from the CAST GG genotype. The MC4R (G 0.208/A 0.792) AA genotype were involved in increasing backfat thickness, carcass weight, moisture and saturated fatty acid content, and decreasing unsaturated fatty acid content in Duroc meat. These results indicated that the five SNP markers tested can be a help to select Duroc breed to improve carcass and meat quality properties in crossbred pigs.

Abstract
Silver and silver oxide nanoparticles were impregnated on the surface of powdered activated carbon (PAC) using a single-step liquid phase plasma (LPP) method. Spherical silver and silver oxide nanoparticles of 20 to 100 nm size were dipersed evenly on the surface of PAC. The impregnated PAC exhibited a higher activity for the decomposition of bromate than bare PAC. The XPS, Raman and EDX analyses showed that the Ag/PAC composites synthesized by the LPP process.

Abstract
BACKGROUND Lymph node (LN) metastasis is an important prognostic factor in gallbladder cancer (GBCA). LN status has been adopted as a critical element of staging systems. However, the influence of total lymph node count (TLNC) remains unclear. We determined the optimal minimum TLNC and compared the prognostic significance of LN status indices in GBCA. METHODS We retrospectively reviewed medical records of 128 patients with T2 or greater GBCA who underwent LN dissection. We analyzed overall survival (OS) and relevance of the number of metastatic LNs, ratio of metastatic LNs to retrieved LNs (LNR), and TLNC in predicting OS. RESULTS The median OS durations were 120, 35, and 18 months in T2, T3, and T4 GBCA. Five-year OS rates were 73%, 43%, and 0% in T2, T3, and T4 GBCA. LN status did not significantly impact OS in T2 or T4 GBCA. However, all LN indices were significantly correlated with OS in T3 GBCA. Furthermore, multivariate analysis revealed that a metastatic LN count of more than four and a TLNC of more than eight were independent prognostic factors of OS in T3 GBCA. CONCLUSIONS TLNC and the number of positive LNs may be more important prognostic factors than LNR in T3 GBCA. Additionally, accurate staging may not be achieved in cases of T3 GBCA if the total number of retrieved LNs is less than eight. Thus, to ensure proper staging, we recommend that surgeons harvest more than eight LNs in patients with T3 GBCA.

Abstract
Presence of individual fatty acid ethyl esters (FAEEs) in meconium is considered to be a reliable biomarker of prenatal alcohol exposure, and their concentration has been found to be linearly associated with poor postnatal development, supporting the widely extended idea that ethanol is a non-threshold teratogen. However, a growing number of epidemiological studies have consistently found a lack of adverse short- and long-term fetal outcomes at low exposure levels. We therefore aimed to investigate the relationship between the concentration of individual FAEEs and prenatal alcohol exposure in meconium samples collected within the first 6 to 12?h after birth from 182 babies born to abstainer mothers and from 54 babies born to women who self-reported either light or moderate alcohol ingestion in the second or third trimester of pregnancy. In most cases, the individual FAEE concentrations were negligible and not significantly different (P >0.05) between exposed and control babies. The concentrations appeared to increase linearly with the dose only in the few babies born to mothers who reported >3 drinks/week. These results provide evidence that the correlation between prenatal alcohol exposure and individual FAEE concentrations in meconium is non-linear shape, with a threshold probably at 3 drinks/week.

Abstract
AIM Hyponatraemia is a common in surgical practice, but its clinical impact in patients with colorectal cancer has not been evaluated. METHOD We retrospectively assessed 2944 patients who had been admitted to Chonnam National University Hwasun Hospital, Korea with a diagnosis of colorectal cancer. In order to determine the relationship between the serum sodium level and 3-year mortality, we categorized the patients as having normonatraemia (135-147 mEq/l), or mild (130-134 mEq/l), moderate (125-129 mEq/l) or severe hyponatraemia (< 125 mEq/l). RESULTS Hyponatraemia, defined as a serum sodium level of < 135 mEq/l, was evident in 27.6% of patients during hospitalization. Declining serum sodium levels were associated with increasing age, a higher number of comorbidities, a more advanced TNM stage and worsening biochemical parameters. In a multivariate Cox-proportional regression analysis, the mortality risk was correlated with the severity of hyponatraemia [hazard ratio (HR) 1.65, 95% CI 1.38-1.96; HR 2.24, 95% CI 1.69-2.98; HR 2.20, 95% CI 1.25-3.90, for patients with mild, moderate, and severe hyponatraemia, respectively, compared with patients with normonatraemia]. An independent association between hyponatraemia and long-term mortality was sustained among various subpopulations and patients with persistent hyponatraemia had a worse prognosis than those with hyponatraemia that resolved. CONCLUSION A substantial proportion of patients developed hyponatraemia during hospitalization, and the long-term mortality risk increased even in mild cases of hyponatraemia. Hyponatraemia should be considered as an important prognostic factor in colorectal cancer.

Abstract
The present study was designed to investigate if exposure to dried ginger during pregnancy would increase the risk of adverse fetal and neonatal outcomes. Participants consisted of 159 singleton pregnant women who received dried ginger as a herbal medication. We also included a control group of 306 pregnant women who had not been exposed to any herbal medication or any known teratogen. No increased risk of major malformations was detected in exposed women (OR = 4.9; 95% CI 0.9-25.5; p = 0.051). The incidence of stillbirths in the exposed group was marginally higher than in the controls (OR = 7.8; 95% CI 0.9-70.3; p = 0.05). The risk was more evident when the exposed group was compared with the general population in the Republic of Korea (OR = 7.9; 95% CI 2.9-21.4; p < 0.0001). Other fetal and neonatal study outcomes investigated in the exposed group were similar (p > 0.05) to the controls. In conclusion, dried ginger does not appear to be a major teratogen. However, due to the limitations of the study, e.g. the large variability in the dose of dried ginger in the exposed group, as well as the concomitant exposure to other herbal medications, the increased incidence of stillbirths requires confirmation in larger cohort studies.

Abstract
Compromised T-cell immunity persists for up to 1 year after autologous stem cell transplantation (ASCT), and patients treated with ASCT are more likely to develop atypical lymphoid hyperplasia that mimics tumor recurrence. Here, we present a case of cervical lymphadenitis due to cytomegalovirus (CMV) reactivation in a patient who had undergone ASCT for Burkitt lymphoma, which mimicked tumor recurrence on computed tomography and positron emission tomography-computed tomography 6 months after ASCT. This lesion was confined to the regional lymph nodes and was not accompanied by signs of systemic involvement, such as fever, splenomegaly, an elevated C-reactive protein level, or viremia. The localized CMV lymphadenitis resolved spontaneously without treatment after 6 months (12 months after ASCT) and the elevated CMV immunoglobulin-M titer normalized 6 months after resolution. Our experience with this case suggests that cautious follow-up without anti-CMV treatment should be considered in cases of post-ASCT localized CMV lymphadenitis without systemic involvement in patients with complete engraftment.

Abstract
INTRODUCTION Liver stiffness measurements (LSMs) using transient elastography (TE) provide a noninvasive means to assess liver fibrosis that correlate with hepatic cholestasis. However, few studies have examined the correlation of TE to obtain LSMs with perioperative clinical and laboratory parameters in living donor liver transplantation (LDLT). PATIENTS AND METHODS We retrospectively reviewed forty-eight subjects who underwent LDLT between November 2010 and October 2012. All donors and recipients underwent TE, abdominal computed tomography (CT), and biochemical tests within 1 month before and at 1 week after transplantation. Using a cut-off LSM of 7.5 kPa, which we arbitrarily assigned to be indicative of significant fibrosis, we divided our study population into ≤7.5 kPa (group L; n = 15, 31.3%) versus >7.5 kPa; (group H; n = 33, 68.8%). RESULTS Pretransplantation serum total bilirubin, international normalized ratio, and Model for End-stage Liver Disease scores of recipients were significantly higher in group H than group L. Regarding the pretransplantation donor characteristics, the graft-recipient weight ratio was significantly smaller among those in group H (P = .039). In addition, the post-transplantation 1-week serum total bilirubin level was significantly higher in group H (2.3 mg/dL versus 1.2 mg/dL, P = .015), although neither biliary complications norhepatic congestion was identified by abdominal CT. Among the 1-week post-transplantation laboratory findings, only total bilirubin positively correlated with LSM (P = .044). CONCLUSIONS This pilot study suggested that a high LSM after LDLT suggests intrahepatic cholestasis and portal hypercirculation in the graft, irrespective of liver fibrosis, outflow obstruction, or biliary obstruction.

Abstract
BACKGROUND This study was undertaken to investigate risk factors of mortality in patients with fulminant hepatic failure (FHF). METHODS Fifty-three patients with FHF treated from January 2006 to April 2011 were allocated to a spontaneous survival group (group 1), a death without liver transplantation (LT) group (group 2), and an LT group (group 3). To analyze risk factors associated with mortality in FHF, we excluded group 3 patients. Clinical features, Model for End-Stage Liver Disease (MELD) scores, and King's College Hospital criteria at the time of hepatic encephalopathy in group 2 were compared with those of group 1. RESULTS The causes of FHF were acute viral infection (n = 29, hepatitis A:B, 28:1), drugs (n = 18; including 4 acetaminophen and 14 herbal medication), autoimmune (n = 4), and miscellaneous (n = 2). Of the 53 patients, 19 were allocated to group 1, 18 to group 2, and 16 to group 3. According to univariate analysis, risk factors for mortality in group 2 were acute renal failure requiring renal replacement therapy and a MELD score ≥30 at the time of hepatic encephalopathy. However, by multivariate analysis, a MELD score ≥30 was the only independent risk factor for mortality in group 2 (P = .042; hazard ratio, 4.500). CONCLUSIONS A MELD score ≥30 was found to be the only independent risk factor of mortality in FHF patients without LT. Therefore, the findings of this study suggest that these patients may need emergent LT for survival.

Abstract
PURPOSE To assess the risk of malignancy of thyroid incidentalomas found on 18F-FDG PET/CT by US features and cytologic results, and to evaluate the clinical usage of a combination of US features and cytology for post-FNA management of thyroid incidentalomas on 18F-FDG PET/CT. MATERIALS AND METHODS From September 2006 to December 2008, 132 patients with 134 thyroid incidentalomas detected on 18F-FDG PET/CT who had undergone US and US-FNA were included in this study. We evaluated the malignancy rate of thyroid incidentalomas in different subgroups subdivided by US features and US-FNA cytology results. Several variables were compared between the benign and malignant group. RESULTS The risk of malignancy was 58.2 % (78/132) in thyroid incidentalomas on 18F-FDG PET/CT. Age, gender, and tumor size were not significantly different between the malignant and benign group. Malignancy rate of thyroid incidentalomas was significantly higher in the suspicious malignant (88.9 %) than in the probably benign group (11.3 %) on US (p < 0.001). Malignancy rates were high in thyroid nodules with "malignancy", "suspicious for malignancy", or "follicular neoplasm" on cytologic results, regardless of US features. However, malignancy rates of thyroid incidentalomas with "unsatisfactory" or "benign" results on cytology were higher in the suspicious malignant (75 %, 12.5 %, respectively) than in the probably benign (0 %) group on US. CONCLUSIONS This study demonstrated that the risk of malignancy was high in thyroid incidentalomas on 18F-FDG PET/CT even without suspicious US features. However, there was no malignancy in nodules with no suspicious US features and benign cytology. Based on these results, we concluded that US may not replace FNA in the diagnosis of PET incidentalomas, and that a follow-up may be considered of thyroid incidentalomas with benign cytology and no suspicious US features.

Abstract
Losartan and licochalcon A interact with cytochrome P-450 (CYP) enzymes and P-glycoprotein (P-gp), and the increase in the use of health supplements may result in licochalcon A being taken concomitantly with losartan to treat or prevent cardiovascular diseases as a combination therapy. The effect of licochalcon A, a natural flavonoid, on the pharmacokinetics of losartan and its active metabolite, EXP-3174, was investigated in rats. Pharmacokinetic parameters of losartan and EXP-3174 were determined after oral administration of losartan (9 mg/kg) to rats in the presence or absence of licochalcon A (0.5, 2.5 and 10 mg/kg). The effect of licochalcon A on P-glycoprotein (P-gp) as well as CYP3A4 and 2C9 activities was also evaluated. Licochalcon A inhibited CYP3A4 and CYP2C9 enzyme activities with 50% inhibition concentrations (IC50) of 2.0 and 0.1 microM, respectively. In addition, licochalcon A significantly enhanced the cellular accumulation of rhodamine-123 in a concentration-dependent manner in MCF-7/ADR cells overexpressing P-gp. The pharmacokinetic parameters of losartan were significantly altered by licochalcon A. Licochalcon A (2.5 mg/kg or 10 mg/kg) increased AUC0-infinity of losartan by 33.4-63.2% and Cmax of losartan by 34.0-62.8%. The total body clearance (CL/F) was significantly decreased (2.5 mg/kg, p < 0.05; 10 mg/kg, p < 0.01) by licochalcon A. Consequently, the absolute bioavailability of losartan in the presence of licochalcon A increased significantly (2.5 mg/kg, p < 0.05; 10 mg/kg, p < 0.01) compared to that in the control group. The relative bioavailability (R.B.) of losartan was 1.15- to 1.63-fold greater than that of the control group. However, there was no significant change in Tmax and t1/2 of losartan in the presence of licochalcon A. Licochalcon A (10 mg/kg) increased the AUC0-infinity of EXP-3174 but this was not significant. Furthermore, concurrent use of licochalcon A (10 mg/kg) significantly decreased the metabolite-parent AUC ratio (M.R.) by 20%, suggesting that licochalcon A inhibited the CYP-mediated metabolism of losartan to its active metabolite, EXP-3174. In conclusion, the enhanced oral bioavailability of losartan in the presence of licochalcon A may mainly result from decreased P-gp-mediated efflux transporter in the small intestine and from the inhibition of CYP 3A- and CYP2C9-mediated metabolism in the small intestine and liver and/or from the reduction of total body clearance of losartan by licochalcon A.

Abstract
PURPOSE To evaluate the rate of the elastography-pathology discordance, and evaluate which various factors have an effect on discordant elastography images (DEI) of breast lesions. MATERIALS AND METHODS Elastography images of 284 pathologically confirmed breast lesions of 233 patients were evaluated. Elasticity scores were compared to pathology results, and lesions were divided into 4 groups: benign concordant/discordant, and malignant concordant/discordant. The rate of DEI among benign and malignant lesions was calculated and compared. Patient, lesion factors and image adequacy were compared among the concordant and discordant groups for analysis. RESULTS Among the 284 breast lesions, 225 (79.2%) were benign, and 59 (20.8%) were malignant. The rate of DEI among malignant lesions was significantly higher than in benign lesions, i. e., 52.5 vs. 3.1% (p < 0.001). Discordant images were more significantly seen in patients with extremely dense breasts on mammography in benign lesions, 42.9 vs. 11.9% (p = 0.034). Discordant images were more significantly seen in malignant lesions < 10 mm or ≥ 20 mm (p = 0.006), and those with inadequate images (64.5 vs. 35.5%, p < 0.001). CONCLUSION The rate of DEI was higher in malignant lesions than in benign lesions. Dense breast parenchyma, lesion size and image adequacy showed significance in discordant images of elastography which need consideration in image acquisition and interpretation.

Abstract
Oxidative stress is thought to be a causative factor for age-related damage in a wide variety of cellular constituents that can lead to dysfunction and various pathological conditions, including the inflammatory process. At the molecular level, the redox-sensitive transcription factor, NF-κB plays a key role in the regulation of the inflammatory process, along with cytokines, cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS). We studied the mechanism underlying the modulation of the inflammatory reaction with age by investigating NF-κB activation and the expression of COX-2, iNOS, and cytokines genes in hepatic tissues isolated from young and old rats. We expanded our investigation of these factors in rats injected with the inflammatory activator, lipopolysaccharide (LPS). Data showed that NF-κB activity was up-regulated with age and was further enhanced by LPS injection, indicating an increased susceptibility and sensitivity to the inflammatory stimulus with age. To explore further the molecular events leading to NF-κB activation, we investigated the inhibitory component of NF-κB complex, IκB. Cytosolic IκBα, but not IκBβ, was significantly decreased in both old and LPS-treated rats, signifying the enhanced migration of cytosolic NF-κB complex into the nucleus following dissociation from the inhibitor. The appearance of the polypeptide, p65, as determined in the nucleus, corresponded with the change in IκBα, providing further supporting evidence for the molecular process involved in NF-κB activation. Our additional investigation of two proinflammatory-related enzymes, COX-2 and iNOS, and three cytokines, interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α, clearly showed aged-related increases, in corroboration with the NF-κB activation. Our results demonstrated that LPS injection caused the enhanced gene expression of inducible proinflammatory proteins, COX-2 and iNOS through NF-κB activation.

Abstract
BACKGROUND We evaluated whether complementary and alternative medicine (CAM) use influenced outcomes [survival and health-related quality of life (HRQOL)] of cancer patients whose condition had just been judged terminal. PATIENTS AND METHODS From July 2005 to October 2006, we conducted a prospective cohort study of 481 terminally ill cancer patients at 11 university hospitals and the National Cancer Center in Korea. We assessed how the use of CAM affected HRQOL and survival. RESULTS In a follow-up of 481 patients and 163.8 person-years, we identified 466 deceased cases. On multivariate analyses, CAM users did not have better survival compared with nonusers [adjusted hazard ratio (aHR), 0.91; 95% confidence interval (CI) 0.74-1.10]. Among mind-body interventions, prayer showed significantly worse survival (aHR, 1.56; 95% CI, 1.00-2.43). Clinically, CAM users reported significantly worse cognitive functioning (-11.6 versus -1.3; P < 0.05) and fatigue (9.9 versus -1.0; P < 0.05) than nonusers. Compared with nonusers in subgroup analysis, users of alternative medical treatments, prayer, vitamin supplements, mushrooms, or rice and cereal reported clinically significant worse changes in some HRQOL subscales. CONCLUSION While CAM did not provide any definite survival benefit, CAM users reported clinically significant worse HRQOLs.

Abstract
PURPOSE OF INVESTIGATION Obesity is correlated with low education, low economic status, and lower rates of Pap smears, which are known as socio-demographic risk factors for cervical cancer. However, the association between obesity and high-risk human papillomavirus (HR-HPV) infection, the necessary cause of cervical cancer, and its related precursors, is not established. MATERIALS AND METHODS The authors examined the association between obesity and HR-HPV infection in 6,868 patients, who participated in annual health examinations at the Kangbuk Samsung Hospital in Seoul, Korea, from January through December 2007. RESULTS The prevalence of HR-HPV infection was 14.8%. Women infected with HR-HPV had a lower body mass index (BMI), when compared with non-infected women. After adjustment for alcohol intake, cigarette smoking, and marital status, HR-HPV infection was found to be negatively associated with BMI. When the analysis was stratified according to BMI, the risk of HR-HPV infection was significantly lower among those who were overweight (OR = 0.817, 95% CI = 0.680-0.982), or obese (OR = 0.688, 95% CI = 0.556-0.851), when compared with women with normal weight. CONCLUSION HR-HPV infection was associated with obesity defined by BMI, with a lower prevalence of infection observed in obese women.

Abstract
INTRODUCTION The role of lymphocyte cross-matches (LCM) remains controversial in the liver transplant field. The aim of this study was to correlate the risk for acute rejection episodes and graft survival in liver transplantation with pretransplant LCM results. PATIENTS AND METHODS We enrolled 184 adult liver transplantation patients, excluding pediatric and second grafts. The 129 living donor and 55 deceased donor liver transplantations were divided into 2 groups: LCM (+); (n=20) and LCM (-); (n=164). RESULTS There were no differences in the demographic features, such as gender and recipient age, original disease, Model for End-Stage Liver Disease score, donor type, number of human leukocyte antigen mismatches, and cold ischemia times. There were no hyperacute rejection episodes in the LCM (+) group. Also, posttransplant complications such as acute rejection episode, biliary complication, or hepatic artery thrombosis were not different. Acute rejection episodes occurred in 5.0% of the LCM (+) group and 15.2% of the LCM (-) group (P=.317). Bile duct complications after transplantation arose in 20.0% of the LCM (+) group and in 32.9% of the LCM (-) group (P=.312). The 2 groups showed no difference in graft survival rate analyzed by the Kaplan-Meier method according to LCM results. CONCLUSION Pretransplant LCM results were not associated with overall graft survival or acute rejection episodes in this study.

Abstract
CONTEXT As an inhibitor of CYP2C9, CYP2D6 and P-gp, myricetin might affect the bioavailability of carvedilol when myricetin and carvedilol are used concomitantly for the prevention or therapy of cardiovascular diseases as a combination therapy. However, the effect of myricetin on the pharmacokinetics of carvedilol has not been reported in vivo. OBJECTIVE This study investigated the effects of myricetin on the pharmacokinetics of carvedilol after oral or intravenous administration of carvedilol in rats. MATERIALS AND METHODS Carvedilol was administered orally or intravenously with or without oral administration of myricetin to rats. RESULTS The effects of myricetin on P-gp, CYP2C9 and 2D6 activity were evaluated. Myricetin inhibited CYP2C9 and CYP2D6 enzyme activity with IC50 of 13 and 57 μM, respectively. In addition, myricetin significantly enhanced the cellular accumulation of rhodamine-123 in MCF-7/ADR cells overexpressing P-gp. Compared with the control group, the AUC was significantly increased by 52.0-85.1%, and the C(max) was significantly increased by 93.1-133.4% in the presence of myricetin after oral administration of carvedilol. Consequently, the relative bioavailability of carvedilol was increased by 1.17- to 1.85-fold and the absolute bioavailability of carvedilol in the presence of myricetin was increased by 18.1-86.4%. T(max) was significantly decreased. DISCUSSION AND CONCLUSION The enhanced oral bioavailability of carvedilol may result from both inhibition of CYP2C9 or CYP2D6-mediated metabolism and P-gp-mediated efflux of carvedilol in small intestine and/or in liver by myricetin rather than reducing renal elimination. Concomitant use of myricetin or myricetin-containing dietary supplements with carvedilol will require close monitoring for potential drug interactions.

Abstract
The effects of curcumin, a natural anti-cancer compound, on the bioavailability and pharmacokinetics of tamoxifen and its metabolite, 4-hydroxytamoxifen, were investigated in rats. Tamoxifen and curcumin interact with cytochrom P450 (CYP) enzymes and P-glycoprotein, and the increase in the use of health supplements may result in curcumin being taken concomitantly with tamoxifen as a combination therapy to treat or prevent cancer. A single dose of tamoxifen was administered orally (9 mg x kg(-1)) with or without curcumin (0.5, 2.5 and 10 mg x kg(-1)) and intravenously (2mg x kg(-1)) with or without curcumin (2.5 and 10 mg x kg(-1)) to rats. The effects of curcumin on P-glycoprotein (P-gp) and CYP3A4 activity were also evaluated. Curcumin inhibited CYP3A4 activity with 50% inhibition concentration (IC50) values of 2.7 microM. In addition, curcumin significantly (P < 0.01 at 10 microM) enhanced the cellular accumulation of rhodamine-123 in MCF-7/ADR cells overexpressing P-gp in a concentration-dependent manner. This result suggested that curcumin significantly inhibited P-gp activity. Compared to the oral control group (given tamoxifen alone), the area under the plasma concentration-time curve (AUC(0-infinity)) and the peak plasma concentration (C(max)) of tamoxifen were significantly (P < 0.05 for 2.5 mg x kg(-1); P < 0.01 for 10 mg x kg(-1)) increased by 33.1-64.0% and 38.9-70.6%, respectively, by curcumin. Consequently, the absolute bioavailability of tamoxifen in the presence of curcumin (2.5 and 10 mg x kg(-1)) was 27.2-33.5%, which was significantly enhanced (P < 0.05 for 2.5 mg x kg(-1); P < 0.01 for 10 mg x kg(-1)) compared to that in the oral control group (20.4%). Moreover, the relative bioavailability of tamoxifen was 1.12- to 1.64-fold greater than that in the control group. Furthermore, concurrent use of curcumin significantly decreased (P < 0.05 for 10 mg x kg(-1)) the metabolite-parent AUC ratio (MR), implying that curcumin may inhibit the CYP-mediated metabolism of tamoxifen to its active metabolite, 4-hydroxytamoxifen. The enhanced bioavailability of tamoxifen by curcumin may be mainly due to inhibition of the CYP3A4-mediated metabolism of tamoxifen in the small intestine and/or in the liver and to inhibition of the P-gp efflux transporter in the small intestine rather than to reduction of renal elimination of tamoxifen, suggesting that curcumin may reduce the first-pass metabolism of tamoxifen in the small intestine and/or in the liver by inhibition of P-gp or CYP3A4 subfamily.

Abstract
No information is currently available on the safety of methylephedrine, a component of various cold medications available in South Korea. With previous approval by an Institutional Review Board, 349 women inadvertently exposed to methylephedrine during the 1st trimester of pregnancy and an age- and gravidity-matched control group, were enrolled in a prospective cohort study. Study outcomes, for example gestational age at birth, birth weight and major and minor malformations were evaluated in 282 cases and 280 controls. Exposure to methylephedrine was at a gestational age of 4.0 weeks (median), at doses ranging from 52.5 to 1,575 mg/day, for a median duration of 3 (range: 1-30) days. No differences were observed between cases and controls in any of the pregnancy outcomes studied. There were 4/265 (1.5%) babies born with major malformations in the case group and 4/260 (1.5%) in the control group. In conclusion, inadvertent exposure to methylephedrine as a component of over-the counter oral cold remedies in early pregnancy was not associated with an increased rate of adverse pregnancy outcomes. Co-exposure with acetaminophen, cigarette smoking or alcohol did not appear to modify the outcomes.

Abstract
OBJECTIVE To increase vigilance among gynecological surgeons for the presence of accessory polar renal artery (APRA) encountered with transperitoneal systemic laparoscopic paraaortic lymphadenectomy (LPAL). METHODS A retrospective review was conducted on 156 women who underwent LPAL for various gynecologic malignancies between November 2003 and December 2009. RESULTS The median age, parity, body mass index, and number of previous abdominal surgeries, respectively, of the women were 52 years (range, 23-82 years), two (range, 0-7), 24.1 kg/m2 (range, 17.4-35.0 kg/m2), and 0 (range, 0-3). During the study period, we found four women with APRA. There were three cases of right lower APRAs arising from the abdominal aorta, caudal to the inferior mesenteric artery (IMA), terminating at the parenchyma of the lower pole of the right kidney. In the other case, the APRA arose from the abdominal aorta superior to the IMA. There were no vascular complications, such as transection or ligation of the APRA. CONCLUSION It is important for the gynecological oncologic surgeon to have knowledge of retroperitoneal vascular anatomy, experience in laparoscopic surgery, and an accurate surgical technique to avoid vascular injury during LPAL.

Abstract
BACKGROUND AND OBJECTIVE Lymphocyte-oriented kinase deficiency encoded by the serine/threonine kinase 10 (STK10) gene correlates with the intracellular adhesion molecule 1 (ICAM-1)/lymphocyte function associated antigen 1 (LFA-1) complex in aspirin hypersensitivity. This study investigated the association between single nucleotide polymorphisms (SNPs) of STK10 and aspirin-intolerant asthma (AIA). METHODS A total of 54 SNPs were genotyped in 163 AIA patients and 429 aspirin-tolerant asthma (ATA) controls. RESULTS Logistic regression revealed that a synonymous variant (rs2306961G>A) had the most significant association with AIA (P = .008 under the codominant model; P = .004 under the dominant model), suggesting that tissue-specific codon usage between Lys_TTT and Lys_CTT could play a role in regulating expression of STK10 in airway epithelium. Haplotype analysis revealed that 4 haplotypes, including STK10_BL4-ht1, which is unique to rs2306961G>A, were significantly associated with aspirin hypersensitivity in asthmatics (P < .05). CONCLUSIONS Although replications in independent cohorts and further functional evaluations are needed, our preliminary findings suggest that STK10 polymorphisms might be susceptible genetic markers of AIA and that gene expression could be mediated by tissue-specific codon usage.
