Objectives: ：Based on the fact that cognitive functions decline known as comorbid symptoms of depression can precede depression, this study seeks to observe the effects of depressive symptoms and anxiety symptoms on cognitive function in healthy subjects. Methods: ：To recruit 50 general populations to evaluate cognitive and clinical symptoms and to find out the effects of clinical symptoms on cognitive functions, Pearson correlation and multivariate regression were conducted. Correlation analysis of subdomain cognitive function was conducted for reliability analysis. Results: ：Trail making test-B that evaluates the execution function correlates with depressive symptoms (r=0.300, p=0.03) and age (r=0.323, p=0.02). Depressive symptoms (β=0.304, p=0.03) and age (β=0.335, p=0.01) were significantly related to Trail making test -B (Adjusted R2 =0.148). Subjective cognitive tests correlates with anxiety symptoms (r=0.434, p=0.002). In the correlation between cognitive functional items, Subjective cognitive tests was found to be correlated with other test except Spotter. Conclusions ：In this study, depressive symptoms contribute independently to executive functions in addition to demographic characteristics such as age and duration of education. Given that cognitive decline is a common long-term clinical outcome in depression, we expect active early intervention and evaluation of cognitive function to be helpful.

Transradial percutaneous coronary artery interventions are increasingly used because of low complication rates and patients' convenience. However, the radial artery is more vulnerable to damage due to its small diameter and frequent anatomical variations. We experienced a case of forearm compartment syndrome after transradial percutaneous coronary artery intervention which has not been reported in Korean literature yet. We report the case with a review of the literature.

Alcoholism is caused by a complex interaction between genetic and environmental factors. Findings obtained from several studies indicate that some tissue damage occurring in alcohol abusers is due to the generation of reactive oxygen species during the ethanol metabolism The objective of this study was to examine the associations between the polymorphisms of glutathione S-transferase (GST) M1 and T1 genes and Korean male patients with alcoholism. We investigated the distribution of deletion of GSTM1 and GSTT1 in Korean male patients diagnosed with alcoholism (n=133) and Korean male control subject without alcoholism (n=91) with polymerase chain reaction (PCR) method. GSTM1 showed significant associations with alcoholism susceptibility (p=0.0002). But GSTT1 showed no significant associations (p=0.0948). In combined analysis, both gene deletion and GSTM1 deletion were associated with alcoholism (p<0.0001 and p<0.0150). These results suggest that GSTM1 gene deletion might play an important role in risk for alcoholism.

Purpose: Venous thromboembolism (VTE) is a major complication for hip fracture patients, and may exist preoperatively. This study aimed to examine the prevalence of VTE after immediate screening in hip fracture patients. Materials and Methods: Hip fracture patients with an elevated level of D-dimer underwent screening for VTE using computed tomography (CT) angiography. Anticoagulation treatments were administered preoperatively to patients diagnosed with VTE, followed by administration of additional anticoagulation postoperatively. Medical records were reviewed to identify risk factors for preoperative VTE and determine the prognosis of the patients. Results: Among 524 hip fracture patients, 66 patients (12.6%) were diagnosed with VTE, including 42 patients with deep vein thrombosis (DVT), 17 patients with pulmonary thromboembolism (PTE), and 7 patients with both DVT and PTE. Of the patients with VTE, 68.2% were diagnosed within 24 hours of injury, and 33.3% of these patients had PTE. VTE patients showed a tendency toward being overweight (P<0.01) and not on anticoagulant medication (P=0.02) compared to patients without VTE. The risk of VTE was higher for femur shaft fractures (odds ratio [OR] 4.83, 95% confidence interval [CI] 2.18-10.69) and overweight patients (OR 2.12, 95% CI 1.17-3.85), and lower for patients who were previously on anticoagulants (OR 0.36, 95% CI 0.18-0.74). Patients with preoperatively diagnosed VTE were asymptomatic before and after surgery. Conclusion Clinicians should be aware that VTE may be present within 24 hours of injury, and screening for VTE or prophylactic measures should be considered for high-risk patients.

Levofloxacin is a bactericidal broad spectrum antibiotic against Gram-positive and Gram-negative pathogens. A randomized, two-treatment, two-period, two-way crossover study was conducted to evaluate the bioequivalence of Lectacin 250 mg tablet, a generic levofloxacin, to its reference drug, Cravit 250 mg tablet. Each period was separated by a 7-day washout. Serial blood samples were collected until 24 h after dosing and plasma levofloxacin concentrations were determined using a high performance liquid chromatography. Pharmacokinetic parameters were analyzed using K-BE Test 2007 and BA calc 2007 (Ministry of Food and Drug Safety, Cheongju-si, South Korea). The peak concentration (Cmax) and the area under the plasma concentration versus time curve from 0 to the last measurable concentration (AUC(0-t)) for the generic and reference levofloxacin were 4.48+/-0.89 mg/L and 4.46+/- 0.95 mg/L, and 25.33+/-4.12 mg*h/L and 25.77+/-4.01 mg*h/L, respectively, leading to a geometric mean ratio (90% confidence interval) of the generic to the reference levofloxacin of 1.0060 (0.9339-1.0842) and 0.9810 (0.9476-1.0159), respectively, for Cmax and AUC(0-t). Lectacin 250 mg tablet is bioequivalent to Cravit 250 mg tablet.

Pre-B-cell leukemia transcription factor 1 (PBX1), which is located on chromosome 1q23, was recently reported to be associated with type 2 diabetes mellitus. We examined whether single nucleotide polymorphisms (SNPs) of the PBX1 gene are associated with overweight/obesity in a Korean population. We genotyped 66 SNPs in the PBX1 gene and investigated their association with clinical phenotypes found in 214 overweight/obese subjects and 160 control subjects using the Affymetrix Targeted Genotyping chip array. Seven SNPs (g.+75186C>T, g.+78350C>A, g.+80646C>T, g.+138004C>T, g.+185219G>A, g.+191272A>C, and g.+265317T>A) were associated with the risk of obesity in three models (codominant, dominant, and recessive) (P=0.007-0.05). Haplotype 1 (CAC) and 3 (TAC) of block 3 and haplotype 2 (GGAAT) of block 10 were also strongly associated with the risk of obesity. In the control group, subjects that had homozygote for the major allele for both g.+185219G>A and g.+191272A>C showed lower high density lipoprotein-cholesterol (HDL-C) level compared to those possessing the minor allele, suggesting that the association between the homozygote for the major allele for both g.+185219G>A and g.+191272A>C and HDL-C is attributable to the increased risk of obesity. This study suggests that the PBX1 gene is a possible risk factor in overweight/obese patients.

This paper aimed to review currently available cohort studies of subjects with mood disorders such as major depressive disorder (MDD) and bipolar disorder (BD). Using the PubMed and KoreaMed databases, we reviewed eight major cohort studies. Most studies recruited participants with MDD and BD separately, so direct comparison of factors associated with diagnostic changes was difficult. Regular and frequent follow-up evaluations utilizing objective mood ratings and standardized evaluation methods in a naturalistic fashion are necessary to determine detailed clinical courses of mood disorders. Further, biological samples should also be collected to incorporate clinical findings in the development of new diagnostic and therapeutic approaches. An innovative cohort study that can serve as a platform for translational research for treatment and prevention of mood disorders is critical in determining clinical, psychosocial, neurobiological and genetic factors associated with long-term courses and consequences of mood disorders in Korean patients.
