Background: s: Alcohol-related liver disease (ALD) is currently a major indication for liver transplantation (LT) in South Korea. Alcoholic recidivism is a primary concern after LT for ALD. However, it is unclear how patients who have received LT for ALD are managed regarding medical and psychological issues. Furthermore, management approaches vary across centers. This study aims to investigate how these management approaches differ among centers. Methods: We conducted a survey of 19 liver transplant centers in South Korea to gather detailed information on the management protocols and related issues of ALD in LT patients. Results: All 19 centers that responded to the survey had been performing LT for patients with ALD for more than 5 years. Nine out of the 19 centers (47%) stated that a minimum abstinence period of 1–6 months from alcohol was required before evaluating LT and enrolling on the transplant waiting list. Only 2 (10%) and 5 (26%) centers had protocols for assessing alcohol consumption while awaiting LT or for treating alcohol consumption after transplantation, respectively. Monitoring abstinence from drinking before and after LT mostly relied on direct interviews, and alcohol biomarkers were not used. Conclusion Our findings emphasize the importance of consistent patient management guidelines for ALD-LTs in South Korea.

Objective: Pre-treatment anxiety (PA) before chemotherapy increases complaints of chemotherapy-related symptoms (CRS). The results on the association have been inconsistent, and the effect of temperament remains unclear. We aimed to determine whether PA is a risk factor for CRS and the effect of differing temperaments on CRS. Methods: This prospective study comprised 176 breast cancer patients awaiting adjuvant chemotherapy post-surgery. We assessed CRS, PA, and temperament using the MD Anderson Symptom Inventory (MDASI), the Hospital Anxiety and Depression Scale, and the short form of the Temperament and Character Inventory-Revised, respectively. The MDASI was re-administered three weeks after the first chemo-cycle. Results: PA showed weak positive correlation with several CRS after the first cycle; no CRS was significantly associated with PA when pre-treatment depressive symptoms and baseline CRS were adjusted in multiple regression analysis. Moderation model analysis indicated that the PA effect on several CRS, including pain, insomnia, anorexia, dry mouth, and vomiting, was moderated by harm avoidance (HA) but not by other temperament dimensions. In particular, PA was positively associated with CRS in patients with low HA. Conclusion The results in patients with low HA indicate that more attention to PA in patients with confident and optimistic temperaments is necessary.

Background: The purpose of this longitudinal prospective cohort study was to investigate the role of chronotype in the incidence of chemotherapy-induced peripheral neuropathy (CIPN) among women with breast cancer. Methods: We recruited women with breast cancer awaiting adjuvant chemotherapy, including four cycles of docetaxel. Participants reported peripheral neuropathy symptoms of numbness/ tingling at the baseline, and at 4weeks after completion of chemotherapy. Candidate psychiatric factors associated with CIPN were assessed at the baseline, using the Composite Scale of Morningness, the Pittsburgh Sleep Quality Index, and the Hospital Anxiety and Depression Scale. To examine the association between chronotype and CIPN, we built logistic regression models, adjusting for demographic, clinical, and other psychiatric variables. Results: Among 48 participants, 29 participants developed CIPN. The morning chronotype was inversely associated with CIPN (odds ratio, 0.06; confidence interval, 0.01–0.74; P = 0.028) after adjusting for age, BMI, education, type of operation, alcohol use, smoking, sleep quality, depression, and anxiety. Conclusion Our results suggest that the morning chronotype is a protective factor against the development of CIPN in patients with breast cancer who were treated with docetaxel.

Life cycle stages, including daughter sporocysts, cercariae, and metacercariae, of Parvatrema duboisi (Dollfus, 1923) Bartoli, 1974 (Digenea: Gymnophallidae) have been found in the Manila clam Ruditapes philippinarum from Aphaedo (Island), Shinan-gun, Jeollanam-do, Korea. The daughter sporocysts were elongated sac-like and 307-570 (av. 395) μm long and 101-213 (av. 157) μm wide. Most of the daughter sporocysts contained 15-20 furcocercous cercariae each. The cercariae measured 112-146 (av. 134) μm in total length and 35-46 (av. 40) μm in width, with 69-92 (av. 85) μm long body and 39-54 (av. 49) μm long tail. The metacercariae were 210-250 (av. 231) μm in length and 170-195 (av. 185) μm in width, and characterized by having a large oral sucker, genital pore some distance anterior to the ventral sucker, no ventral pit, and 1 compact or slightly lobed vitellarium, strongly suggesting P. duboisi. The metacercariae were experimentally infected to ICR mice, and adults were recovered at day 7 post-infection. The adult flukes were morphologically similar to the metacercariae except in the presence of up to 20 eggs in the uterus. The daughter sporocysts and metacercariae were molecularly (ITS1-5.8S rDNA-ITS2) analyzed to confirm the species, and the results showed 99.8-99.9% identity with P. duboisi reported from Kyushu, Japan and Gochang, Korea. These results confirmed the presence of various life cycle stages of P. duboisi in the Manila clam, R. philippinarum, playing the role of the first as well as the second intermediate host, on Aphae-do (Island), Shinan-gun, Korea.

Objectives: ：The purpose of this study was to investigate the needs for return-to-work support of cancer survivors and related factors in patients with cancer and their caregivers. Methods: ：182 patients and 114 caregivers were recruited. Distress Thermometer and Problem List and scale ranging 0~10 measuring the degree of needs for return-to-work support were utilized. The needs for return-towork support between the patient group and caregiver group (patient’s needs evaluated by the caregiver) were compared, and related factors were investigated using logistic regression analysis. Results: ：34.6% and 28.1% of patients and caregivers reported return-to-work support of cancer survivors is “very necessary”. The degree of needs was 6.60±3.365 points in the patient group and 6.17±3.454 points in the caregiver group, with no significant difference (p=0.282). The needs for return-to-work support evaluated by patients was high when they underwent surgery (OR=2.592, p=0.007), has fertility problems (OR=6.137, p=0.025), has appearance problems (OR=2.081, p=0.041), or has fatigue (OR=2.330, p=0.020). The needs for return-towork support of patients evaluated by caregivers was high when patients treated with breast cancer (vs respiratory cancer, OR=13.038, p=0.022 ; vs leukemia/lymphoma, OR=4.517, p=0.025 ; vs other cancer, OR=13.102, p= 0.019), has work/school problems (OR=4.578, p=0.005), or has depression (OR=3.213, p=0.022). Conclusions ：The degree of needs for return-to-work support of cancer survivors was high, and factors related to the needs were different between the two groups. This suggests that return-to-work support of cancer survivors is required, and clinical characteristics, the distress of patients, and differences between patients and their caregivers should be considered in establishing a support plan.

Gymnophallid metacercariae found in the Manila clam Ruditapes philippinarum (‘Banjirak’ in Korean) from Gochang-gun, Jeollabuk-do, Korea were morphologically and molecularly confirmed to be Parvatrema duboisi (Dollfus, 1923) Bartoli, 1974. The metacercariae were morphologically characterized by having a large oral sucker, small ventral sucker, genital pore some distance anterior to the ventral sucker, no ventral pit, and 1 compact or slightly lobed vitellarium, which were all compatible with P. duboisi. Some of the metacercariae were experimentally fed to mice, and adult flukes were recovered at day 7 post-infection. The morphology of the adult flukes was basically the same as that of the metacercariae except for the presence of uterine eggs; the uterus was filled with up to 40 eggs. The nucleotide sequences (1,193 bp) from ITS regions (ITS1, 5.8S rDNA, and ITS2) of the metacercariae showed 99.7% identity with P. duboisi and 75.7% identity with Gymnophalloides seoi deposited in GenBank. These results confirmed the presence of P. duboisi metacercariae in the Manila clam R. philippinarum in an estuary region of Gochang-gun, Korea.

Purpose: Hepatocellular carcinoma (HCC) patients with major portal vein tumor thrombosis (mPVTT) complications were generally characterized by extremely poor prognoses. The aim of this study was to explore the role of 18F-fluorodeoxyglucose (18F-FDG) PET/CT imaging in predicting HCC complicated by mPVTT. Methods: Five hundred one HCC patients received surgery in our hospital during November 2008 to December 2014, among which 32 patients (6.4%) were diagnosed as HCC complicated by mPVTT. Six cases were excluded for reasons of complex medical conditions, including 2 cases of salvage liver transplantation, 2 cases of re-resection, 1 case of mPVTT combined with inferior vina cava tumor thrombosis, and 1 case of residual portal vein tumor thrombosis. Ultimately, 26 cases were enrolled in this study. The maximal tumor standardized uptake value (SUVmax) was identified as a predictive factor and detected. The univariate and multivariate regression analyses were performed to identify the prognostic factors for recurrence-free survival (RFS) and overall survival (OS) of HCC patients complicated by mPVTT. Results: Our results showed that the median OS was 16 months. The 1-, 3-, and 5-year cumulative OS was 55.6%, 31.7%, and 31.7%, respectively. The multivariate regression analysis revealed that SUVmax ≥ 4.65 was the only independent risk factor for RFS and OS. Conclusion SUVmax was an independent predictor for RFS and OS of patients suffering from both HCC and mPVTT. L ow SUVmax could serve as an effective factor for selecting candidates with low recurrence risks and for helping with improving patient survival after surgical resection.

This clinical practice position statement, a product of the Fatty Liver Research Group of the Korean Diabetes Association, proposes recommendations for the diagnosis, progression and/or severity assessment, management, and follow-up of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus (T2DM). Patients with both T2DM and NAFLD have an increased risk of non-alcoholic steatohepatitis (NASH) and fibrosis and a higher risk of cardiovascular diseases and diabetic complications compared to those without NAFLD. With regards to the evaluation of patients with T2DM and NAFLD, ultrasonography-based stepwise approaches using noninvasive biomarker models such as fibrosis-4 or the NAFLD fibrosis score as well as imaging studies such as vibration-controlled transient elastography with controlled attenuation parameter or magnetic resonance imaging-proton density fat fraction are recommended. After the diagnosis of NAFLD, the stage of fibrosis needs to be assessed appropriately. For management, weight reduction achieved by lifestyle modification has proven beneficial and is recommended in combination with antidiabetic agent(s). Evidence that some antidiabetic agents improve NAFLD/NASH with fibrosis in patients with T2DM is emerging. However, there are currently no definite pharmacologic treatments for NAFLD in patients with T2DM. For specific cases, bariatric surgery may be an option if indicated.

PURPOSE: Although many staging systems have been proposed for hepatocellular carcinoma (HCC), there is no globally accepted system due to the extreme heterogeneity of the disease. We aimed to compare the results of the 7th/8th American Joint Committee on Cancer (AJCC) and the modified Union for International Cancer Control (mUICC) staging systems in patients with HCC. MATERIALS AND METHODS: We collected data from 792 patients who underwent hepatic resection at our center. The Kaplan-Meier method was used to determine disease-free survival and overall survival. To evaluate homogeneity, ‘-2 log likelihood’ was calculated using Cox proportional hazards regression. To measure discriminatory ability, the linear trend chi method and the Cochran-Armitage test for trend were used. The ability to accurately predict survival was verified by cross-validation analysis. RESULTS: Kaplan-Meier curves for disease-free survival and overall survival showed mUICC to be superior to the 7th/8th AJCC. The homogeneity test indicated that mUICC was the best for both disease-free survival and overall survival. In the discriminatory ability test, the chi-square value of mUICC was the best for disease-free survival, while the 7th AJCC had the best value for overall survival. In the cross-validation analysis, all three staging systems had significant predictive power. CONCLUSION: mUICC seemed to be superior to the 7th/8th AJCC after analyzing the data of our surgical patients, although the geographic heterogeneity of HCC might result in differences between the staging systems. We believe that, while the three staging systems allow for the clear stratification of patients into prognostic groups, mUICC may be more appropriate in HCC.
