There are limited data on outcomes after implantation of everolimus-eluting stents (EES) in East Asian patients with small vessel coronary lesions. A total of 1,600 patients treated with XIENCE EES (Abbott Vascular, CA, USA) were divided into the small vessel group treated with one ≤2.5 mm stent (n=119) and the non-small vessel group treated with one ≥2.75 mm stent (n=933). The primary end point was a patient-oriented composite outcome (POCO), a composite of all-cause death, myocardial infarction (MI), and any repeat revascularization at 12 months. The key secondary end point was a device-oriented composite outcome (DOCO), a composite of cardiovascular death, target-vessel MI, and target lesion revascularization at 12 months. The small vessel group was more often female, hypertensive, less likely to present with ST-elevation MI, and more often treated for the left circumflex artery, whereas the non-small vessel group more often had type B2/C lesions, underwent intravascular ultrasound, and received unfractionated heparin. In the propensity matched cohort, the mean stent diameter was 2.5±0.0 mm and 3.1±0.4 mm in the small and non-small vessel groups, respectively. Propensity-adjusted POCO at 12 months was 6.0% in the small vessel group and 4.3% in the non-small vessel group (p=0.558). There was no significant difference in DOCO at 12 months (small vessel group: 4.3% and non-small vessel group: 1.7%, p=0.270).Outcomes of XIENCE EES for small vessel disease were comparable to those for non-small vessel disease at 12-month clinical follow-up in real-world Korean patients.

The Endeavor Resolute® (ER) is a zotarolimus-eluting stent (ZES) with a biocompatible BioLinx polymer. This study prospectively compared the clinical outcomes of 2 versions of ZES, ER and Endeavor Sprint® (ES), in patients with multivessel disease. A total of 488 patients who underwent multivessel percutaneous coronary intervention (PCI) were divided into 2 groups the ER group (n=288) and the ES group (n=200). The primary endpoint was a composite of major adverse cardiac events (MACE) consisting of death, myocardial infarction, and target vessel revascularization after 12 months. In all patients, the prevalence of diabetes was higher in the ER group (42.7% vs. 31.0%, p=0.009). The rate of post-PCI Thrombolysis in Myocardial Infarction flow grade 3 was higher in the ER group (100.0% vs. 98.0%, p=0.028). There were no between-group differences in the in-hospital, 1-month and 12-month clinical outcomes. In the propensity score matched cohort (n=200 in each group), no differences were observed in the baseline and procedural characteristics. There were no statistical differences in the rates of in-hospital, 1-month and 12-month events (12-month MACE in the ER and ES groups: 6.0% vs. 3.5%, p=0.240, respectively). The safety and efficacy of both versions of ZES were comparable in patients with multivessel disease during a 12-month clinical follow-up.

Double outlet right ventricle (DORV) and transposition of the great arteries (TGA) with ventricular septal defect (VSD) and pulmonary stenosis (PS) are complex heart diseases, the treatment of which remains a surgical challenge. The Rastelli procedure is still the most commonly performed treatment. Aortic root translocation including an arterial switch operation is advantageous anatomically since it has a lower possibility of conduit blockage and the left ventricle outflow tract remains straight. This study reports successful aortic root transpositions in two patients, one with DORV with VSD and PS and one with TGA with VSD and PS. Both patients were discharged without postoperative complications.

We report the case of a patient who suffered two events of sudden cardiac arrests separately. Sudden onset of dyspnea and cardiac arrests occurred during cesarean section in a 35-year-old woman who delivered premature baby. Instant chest compression and epinephrine 1 mg was administered. She was diagnosed to have a placenta previa totalis with bleeding preoperatively and placenta accreta was noted intraoperatively. Cesarean hysterectomy was performed due to excessive hemorrhage associated with uterine atony. Another cardiac arrests occurred during hysterectomy. After instant successful resuscitation, she recovered her heart rhythm and transferred to tertiary hospital safely. She was discharged about two months later without any major physical or neurocognitive deficits.

Altered expression of neurotrophic factors as well as neuroinflammation is commonly associated with Major depressive disorder (MDD) and Alzheimer's disease (AD). To investigate whether or not reserpine-induced MDD affects the expression of AD-related proteins, the expression of gamma-secretase components and substrate were measured in brains of ICR mice following reserpine treatment for 15 days. In active avoidance test, total response time and peak slightly increased in the 2 mg/kg reserpine (RSP2)-treated group compared to vehicle-treated group (P<0.05). Expression and phosphorylation of MKP-1, which is a key factor in MDD pathology, were both higher in the RSP2-treated group than the vehicle- and 1 mg/kg reserpine (RSP1)-treated groups (P<0.02). Furthermore, full-length expression of amyloid precursor protein (APP) was enhanced in the RSP1 and RSP2-treated groups compared to the vehicle-treated group, whereas expression of gamma-secretase components decreased (P<0.03). Among the three components of the gamma-secretase complex, nicastrin protein underwent the largest decrease in expression, as detected by Western blotting (P<0.03). Therefore, the data presented here provide additional evidence about the pathological correlation between MDD and AD.

The Korean Society for the Study of Obesity (KSSO) has defined the waist circumference cutoff value of central obesity as 90 cm for men and 85 cm for women. The purpose of this investigation was to determine the corresponding waist circumference values. A total of 3,508 persons in the Korean Rural Genomic Cohort Study were enrolled in this survey. Receiver operating characteristic (ROC) curve analysis was used to find appropriate waist circumference cutoff values in relation to insulin resistance determined by homeostasis model assessment for insulin resistance (HOMA-IR), body mass index (BMI), and components of metabolic syndrome. The optimal waist circumference cutoff values were 87 cm for men and 83 cm for women by ROC analysis to HOMA-IR and 86 cm for men and 83 cm for women by ROC analysis to value with more than two components of metaobolic syndrome. By using a BMI > or =25 kg/m2, 86 cm for men and 82 cm for women were optimal waist circumference cutoff values. In this study, we suggest that the most reasonable waist circumference cutoff values are 86-87 cm for men and 82-83 cm for women.

PURPOSE: To evaluate the efficacy of photodynamic therapy (PDT) with verteporfin for polypoidal choroidal vasculopathy (PCV) in Korean patients. METHODS: Clinical data of patients who were treated with PDT for PCV and followed up for more than 6 months were collected from 14 hospitals around the country. The changes in the best corrected visual acuity, angiographic outcome, retinal thickness measured by optical coherence tomography (OCT), and adverse effects of treatment were evaluated. RESULTS: Eighty six patients (86 eyes) were recruited (male: 75.6%, age: 65.9+/-8.3 years, mean follow-up: 14.8+/-10.2 months). The mean logMAR visual acuity at baseline was 0.55+/-0.32 and did not show any statistically significant difference from the final mean logMAR visual acuity (0.53+/-0.54) (p=0.639). The mean treatment session number of PDT was 2+/-1.2. Visual acuity stabilized or improved in 70.9% of patients. Visual acuity improved by more than 2 lines in 33 eyes (38.4%) and worsened by more than 2 lines in 21 eyes (24.4%) of patients. Vascular leakage decreased in 62.5% of patients in fluorescein angiography and polypoidal lesions disappeared or were reduced in 57.3% of patients in indocyanine green angiography. There was no systemic adverse effect of PDT, but increased subretinal hemorrhage after PDT occurred in 10 eyes (11.6%). CONCLUSIONS: In polypoidal choroidal vasculopathy, photodynamic therapy with verteporfin is safe and effective for preserving visual acuity and reducing vascular leakage and retinal thickness.

BACKGROUND: Postmenopausal status is associated with a 60% increased risk for metabolic syndrome. It is thought to be associated with decreased estrogens and increased abdominal obesity in postmenopausal women with metabolic syndrome. The purpose of this study was to investigate the association between metabolic syndrome components and menopausal status. METHODS: A total of 1,926 women were studied and divided into three groups according to their menstrual stage (premenopausal, perimenopausal or postmenopausal). The presence of metabolic syndrome was assessed using the National Cholesterol Education Program's (NCEP) Adult Treatment Panel III criteria. RESULTS: The prevalence of metabolic syndrome was 7.1% in premenopause, 9.8% in perimenopause, and 24.2% in postmenopause. The strong correlation was noted between the metabolic syndrome score and waist circumference in postmenopause (r = 0.56, P < 0.01) and perimenopause (r = 0.60, P < 0.01). Along the menopausal transition, the risk of metabolic syndrome increased with high triglyceride after the age-adjusted (odds ratio (OR) 1.517 [95% confidence interval (CI) 1.014~2.269] in perimenopausal women and OR 1.573 [95% CI 1.025~2.414] in postmenopausal women). In addition, the prevalence of metabolic syndromeincreased in accordance with elevated alanine aminotransferase (ALT) and gamma-glutamyl transpeptidase (GGT) levels. CONCLUSION: Triglyceride and waist circumference were important metabolic syndrome components, though ALT and GGT may also be related for predicting metabolic syndrome during the transition to menopause.

PURPOSE: The short insulin tolerance test is a simple and reliable method of estimating insulin sensitivity. This study was designed to compare the insulin sensitizing effects of thiazolidinediones (TZDs) on the degree of insulin resistance, determined by a short insulin tolerance test (Kitt) in type 2 diabetic patients. PATIENTS AND METHODS: Eighty-three subjects (mean age = 57.87 +/- 10.78) with type 2 diabetes mellitus were enrolled and received daily one dose of rosiglitazone (4mg) or pioglitazone (15mg). The mean follow-up duration was 25.39 +/- 9.66 months. We assessed insulin sensitivity using HOMA-IR and the short insulin tolerance test before and after TZDs treatment. RESULTS: When we compared patients' characteristics before and after TZDs treatment, the mean fasting glucose level was significantly decreased (183.27 +/- 55.04 to 137.35 +/- 36.42mg/dL, p < 0.001) and the mean HbA1C level was significantly decreased (9.24 +/- 1.96 to 8.11 +/- 1.39%, p < 0.001). Also, Kitt values were significantly increased (2.03 +/- 1.14 to 2.67 +/- 0.97%/min, p = 0.003), whereas HOMA-IR was significantly decreased (2.98 +/- 0.68 to 1.04 +/- 0.24, p < 0.05). When classifying insulin resistance by Kitt values, insulin resistant subjects' values were increased (< 2.5%/min; 1.51 +/- 0.53%/min to 2.63 +/- 0.88, p < 0.001), whereas the values decreased in insulin sensitive subjects (> or = 2.5%/min; 3.50 +/- 0.75%/min to 2.75 +/- 1.12%/min, p = 0.002). CONCLUSION: The glucose lowering effects of TZDs by improving insulin resistance could be determined by using Kitt. However, Kitt may be a beneficial tool to determine TZDs' effects only when patients' Kitt values are less than 2.5%/min.
