PURPOSE: The objective of this study was to translate the obesity-related problems (OP) scale for Koreans and to validate it for use in Korean populations. METHODS: Translation and back-translation of the OP scale was performed and a pilot test was conducted. Following this, patients who had received treatment at the Obesity Center of Inha University Hospital were selected for participation in the field test. Cronbach's alpha (alpha) was used for assessment of the internal consistency of the OP scale. Spearman's correlation coefficients were used to assess the concurrent validity between the OP scale, the EuroQoL-5D (EQ-5D), and the Beck depression inventory (BDI) scale. One-way analysis of variance and t-test were used to assess the factors associated with the OP scale. RESULTS: A total of 67 individuals participated in the field study. The standardized Cronbach's alpha of the OP was 0.913. A significant negative correlation was observed between the OP scale and the EQ-5D and a positive correlation was observed between the OP scale and the BDI (the correlation coefficient with EQ-5D = -0.316, and the BDI = 0.305, P < 0.05). CONCLUSION: The results of this study prove that the Korean version of the OP has been translated and adapted correctly in order to meet the standard of its use.

A right coronary artery to left ventricular fistula with a giant right coronary artery aneurysm is a very rare condition. This requires surgical treatment because of the possibility of rupture of aneurysm, heart failure and infective endocarditis. A 47 years old male patient with dyspnea on exertion for 3 months was diagnosed as having a right coronary artery to left ventricular fistula with a giant right coronary artery aneurysm according to the CT and coronary artery angiography. We resected the aneurysm and performed a coronary artery bypass graft.

PURPOSE: To investigate the correlations between Seoul Neuropsychological Screening Battery (SNSB) scores and the gray matter volumes (GMV) in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI) and cognitively normal (CN) elderly subjects with correcting the genotypes. MATERIALS AND METHODS: Total 75 subjects were enrolled with 25 subjects for each group. The apolipoprotein E (APOE) epsilon genotypes, SNSB scores, and the 3D T1-weighted images were obtained from all subjects. Correlations between SNSB scores and GMV were investigated with the multiple regression method for each subject group using both voxel-based and region-of-interest-based analyses with covariates of age, gender, and the genotype. RESULTS: In the AD group, Rey Complex Figure Test (RCFT) delayed recall scores were positively correlated with GMV. In the MCI group, Seoul Verbal Learning Test (SVLT) scores were positively correlated with GMV. In the CN group, GMV negatively correlated with Boston Naming Test (K-BNT) scores and Mini-Mental State Examimation (K-MMSE) scores, but positively correlated with RCFT scores. CONCLUSION: When we used covariates of age, gender, and the genotype, we found statistically significant correlations between some SNSB scores and GMV at some brain regions. It may be necessary to further investigate a longitudinal study to understand the correlation.

BACKGROUND: Several studies have suggested that elevated levels of hemoglobin A1c (HbA1c) are associated with cardiovascular disease (CVD) in nondiabetic individuals. However, it is unclear whether HbA1c levels can serve as a simple screening marker for increased CVD risk in nondiabetic individuals. Our objective was to evaluate the relationship between HbA1c levels and CVD risk using the Framingham risk score (FRS) in older, apparently healthy nondiabetic Korean adults. METHODS: We retrospectively studied 2,879 Korean adults between the ages of 40 and 79 who underwent voluntary health check-ups at the Health Promotion Center of our hospital from July 2009 to June 2011. Subjects were subdivided based on their HbA1c levels into four groups: tertiles within the HbA1c normal tolerance range and a group for subjects with an increased risk for diabetes (IRD). RESULTS: The mean FRS for the upper tertile (9.6+/-3.8) group was significantly higher than that of the middle tertile (8.4+/-4.0) and lower tertile (7.6+/-3.8) groups. In addition, FRS was highest in the IRD group (10.5+/-3.7). Multiple linear regression analysis demonstrated that HbA1c levels exhibited a significant positive correlation with FRS when adjusted for confounding variables in all subjects (beta+/-standard error [SE], 0.018+/-0.002; R2, 0.131), women (beta+/-SE, 0.023+/-0.003; R2, 0.170), and men (beta+/-SE, 0.016+/-0.004; R2, 0.109). CONCLUSION: HbA1c levels were positively correlated with FRS in older, apparently healthy nondiabetic Korean adults. We propose that HbA1c levels may reflect CVD risk in nondiabetic individuals.

PURPOSE: The purpose of this study is to evaluate the use of second-look ultrasonography (US) for investigating additional suspicious lesions detected on preoperative staging magnetic resonance imaging (MRI) for breast cancer. METHODS: Between September 2008 and August 2010, 1,970 breast MRIs were performed at our medical institution for the evaluation of breast cancer before surgery. Second-look US was recommended for 135 patients with 149 suspicious lesions, following the MRI interpretation, and 108 patients with 121 lesions were included in this study. The detection rate on second-look US, according to the lesion type, diameter, and histopathological outcome, was analyzed. RESULTS: Of the 121 lesions considered in this study, 97 (80.2%) were diagnosed on MRI as masses and 24 (19.8%) as non-mass-like lesions; 105 lesions (86.8%) were correlated and 16 (13.2%) were not correlated with the findings of second-look US. Of the 105 correlated lesions, 29 (27.6%) were proven to be malignant and 76 (72.4%) were benign. Although a greater number of large malignant lesions were correlated on second-look US than small benign lesions, there was no statistically significant difference according to lesion diameter or type, as seen on MRI or pathology. CONCLUSION: We have concluded that second-look US is a useful diagnostic tool for lesions incidentally detected on breast MRI, as in this study, it could identify 86.8% of the MRI-detected breast lesions.

Proteasomes are the primary degradation machinery for oxidatively damaged proteins that compose a class of misfolded protein substrates. Cellular levels of reactive oxygen species increase with age and this cellular propensity is particularly harmful when combined with the age-associated development of various human disorders including cancer, neurodegenerative disease and muscle atrophy. Proteasome activity is reportedly downregulated in these disease conditions. Herein, we report that docosahexaenoic acid (DHA), a major dietary omega-3 polyunsaturated fatty acid, mediates intermolecular protein cross-linkages through oxidation, and the resulting protein aggregates potently reduce proteasomal activity both in vitro and in cultured cells. Cellular models overexpressing aggregation-prone proteins such as tau showed significantly elevated levels of tau aggregates and total ubiquitin conjugates in the presence of DHA, thereby reflecting suppressed proteasome activity. Strong synergetic cytotoxicity was observed when the cells overexpressing tau were simultaneously treated with DHA. Antioxidant N-acetyl cysteine significantly desensitized the cells to DHA-induced oxidative stress. DHA significantly delayed the proteasomal degradation of muscle proteins in a cellular atrophy model. Thus, the results of our study identified DHA as a potent inducer of cellular protein aggregates that inhibit proteasome activity and potentially delay systemic muscle protein degradation in certain pathologic conditions.
