PURPOSE: To evaluate whether factors related to lipid and glucose metabolism have a potential role in the progression of prostate cancer, we measured the mRNA levels of the peroxisome proliferator-activated receptor (PPAR), fatty acid elongase (ELOVL), and two glycolytic enzymes in prostate cancer (CaP) tissues. MATERIALS AND METHODS: Prostate tissues, obtained from radical prostatectomy (n=10) and transurethral resection of prostate (n=18), were quickly frozen in liquid nitrogen for RNA measurements. Transcript signals of PPAR alpha, PPAR gamma, ELOVL2, ELOVL5, phosphoglycerate kinase 1 (PgK1) and phosphoglycerate mutase 2 (PgM2) were measured using a reverse-transcription polymerase chain reaction. RESULTS: The transcript signals of PPAR alpha and PPAR gamma were down-regulated in CaP tissues. In addition, the mRNA level of PgM2 in CaP tissues was lower than that in benign prostatic hyperplasia (BPH) tissues. However, the messages for ELOVL2, ELOVL5, and PgK1 were not significantly changed. CONCLUSIONS: These results suggest that lowering of the PPARalpha, PPARgamma and PgM2 messages may be involved in aberrant and uncontrolled prostate cell growth and differentiation.

Recently, mini-implant is popular in the orthodontic treatment due to its simplicity and convenient surgical procedure. The objective of this study is to provide the anatomical guideline for mini-implant placement by analysing the cortical bone thickness in Korean. Hemi-sections of sixteen maxillae and twenty-two mandibles with normal teeth were used. Interdental areas between the 1st premolar and the 2nd premolar (Group 1), the 2nd premolar and the 1st molar (Gruop 2), and the 1st molar and the 2nd molar (Group 3) were sectioned and then scanned. After setting the axis of teeth, the cortical bone thickness was measured at the distance of 2 mm, 4mm, 6 mm, and 8 mm from alveolar crest. The mean thickness of cortical bone in the maxilla according to distance from alveolar crest was 1.30 +/- 0.63 mm (2 mm), 1.49 +/- 0.62 mm (4mm), 1.72 +/- 0.64 mm (6mm), and 1.90 +/- 0.90 mm (8 mm) at the buccal side and 1.33 +/- 0.47 mm, 1.31 +/- 0.45 mm, 1.37 +/- 0.55 mm, and 1.39 +/- 0.58 mm at the palatal side. In the mandible, that was 3.14 +/- 1.71 mm, 4.31 +/- 2.22 mm, 4.23 +/- 1.94 mm, and 4.30 +/- 1.57 mm at the buccal side and 1.98 +/- 0.88 mm, 2.79 +/- 1.01 mm, 3.35 +/- 1.27 mm, and 3.93 +/- 1.38 mm at the lingual side. The buccal cortical bone thickness in the maxilla was decreased from Group 1 to Group 3, while the thickness of palatal side was no change. In the mandible, it did not show a tendency at the buccal side and it was decreased from Group 1 to Group 3 without significant difference at the lingual side. Therefore, the buccal side of the Group 1 and Group 2 in both the maxilla and mandible seems to be the most appropriate site for a mini-implant placement with taking the stability and retention.

OBJECTIVES: The aim of this study was to develop the Korean version of the Warwick-Edinburgh Mental Well-being Scale (K-WEMWBS) and to examine its factorial structure, reliability, and convergent/discriminant validity. METHODS: In this study, the Warwick-Edinburgh Mental Well-being Scale (WEMWBS), a self-rating measure for assessment of mental well-being, was translated into Korean. It was completed by 222 respondents, including 117 healthy subjects and 105 psychiatric patients from both inpatient and outpatient clinics at Soonchunhyang University Hospitals in Bucheon, Cheonan, and Seoul. RESULTS: The K-WEMWBS showed good content validity. Confirmatory factor analysis supported a single factor structure. The Cronbach's alpha value for the K-WEMWBS was 0.944, which demonstrated good internal consistency. Test-retest reliability at 2-8 weeks was high (0.789). The K-WEMWBS showed high correlations with mental health, positive affect, and quality of life scales. Moderate negative correlation was observed between the K-WEMWBS and the negative affect scale. Discriminant validity was partially identified. Statistically significant differences in scores were observed between the psychiatric patient group and the control group. CONCLUSION: The results of this study indicate that the K-WEMWBS is a reliable and valid instrument for assessment of mental well-being, particularly the positive aspects of mental health.

Purpose: To analyze the degree of psychological distress experienced pre- and postoperatively in patients who underwent radical prostatectomy after being diagnosed with prostate cancer. Materials and Methods: Patients diagnosed with prostate cancer who underwent radical prostatectomy without history of psychiatric disorders were included in this study. The degree of psychological distress was evaluated using hospital anxiety and depression scale (HADS) and distress thermometer (DT) questionnaires preoperatively and at 1, 3, 6, and 12 months postoperatively. Results: Distress was high preoperatively and decreased over the entire period. In addition, HADS-anxiety and HADS-depression scores showed an improved severity, shifting from an abnormal state to a borderline state in some patients. However, the DT score, including emotional problems, spiritual concerns, physical problems, family problems, and practical problems, was slightly higher at 1 month postoperatively compared to preoperatively. Furthermore, even at 12 months postoperatively, about one fifth of patients surveyed had a DT score of 4 or higher, requiring psychiatric intervention. Conclusions Before and after radical prostatectomy, a significant number of patients complained of distress such as anxiety, depression, and insomnia, and they needed help from a specialist because of psychological distress even 12 months postoperatively.Therefore, a close evaluation of the patient’s psychological distress and supportive treatment are needed during the entire pre- and postoperative period.

BACKGROUND/AIMS: To investigate the drug survival rate of tacrolimus (TAC) and analyze the potential predictors of this rate in patients with rheumatoid arthritis (RA) in routine care. METHODS: 2018-01-16: In this retrospective longitudinal study, we enrolled 102 RA patients treated with TAC from April 2009 to January 2014 at a tertiary center in South Korea. The causes of TAC discontinuation were classified as lack of efficacy (LOE), adverse events (AEs), and others. The drug survival rate was estimated using the Kaplan-Meier method and the predictors of this rate were identified by Cox-regression analyses. RESULTS: TAC was discontinued in 27 of 102 RA patients (26.5%). The overall 1-, 2-, 3-, and 4-year TAC continuation rates were 81.8%, 78.4%, 74.2%, and 69.1%, respectively and the median follow-up period from the start of TAC was 32.5 months. The number of TAC discontinuations due to LOE, AEs, and others were 15 (55.6%), 11 (40.7 %), and 1 (3.7%), respectively. The baseline high disease activity was a significant risk factor for TAC discontinuation after adjusting for confounding factors (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.16 to 5.35; p = 0.019). In addition, underlying interstitial lung disease was significantly associated with TAC withdrawal due to AEs (HR, 3.49; 95% CI, 1.06 to 11.46; p = 0.039). CONCLUSIONS In our study, TAC showed a good overall survival rate in patients with RA in real clinical practice. This suggests that the long-term TAC therapy has a favorable efficacy and safety profile for treating RA.

PURPOSE: Paraquat is widely used non-selective contact herbicide. In spite of efforts to improve the outcome in paraquat poisoning, the mortality rate still remains high. The purpose of this study is to assess the predictive factors of prognosis by investigating initial laboratory data on paraquat poisoning. METHODS: The author retrospectively analyzed the clinical features, laboratory data, and outcomes for 130 paraquatpoisoning patients treated from June 1997 to September 2003 at the emergency medical center of Chonnam National University Hospital. RESULTS: The results were as follows: 1) The mortalities were significantly older than the survivors (49.3 years vs 37.6 years, p<0.05). Among the total 130 cases, the survivors numbered 50, and the deceased numbered 80. The mean age of all 130 cases was 44.8+/-16.9 years. 2) The white blood cell count and the levels of serum AST and ALT in the deceased were significantly higher than they were in the survivors. The levels of arterial pH, PaCO 2, base excess, HCO3 -, and serum potassium in the survivors were significantly higher than they were in the deceased. 3) A multivariate Cox-Regression analysis revealed that sex, serum potassium, and arterial HCO3 - were associated with the mortality rate. CONCILUSION: The above data reveal that the ingested amount, the result of the urine sodium dithionite test, and the initial state of laboratory parameters, including the white blood cell count, ABGA (pH, PaCO2, HCO3 -, base excess), serum potassium, AST, and ALT, can be used to predict the outcome of paraquat poisoning.
