The purpose of this extension study was to assess the long-term efficacy and safety of gemigliptin 50 mg in patients with type 2 diabetes mellitus (T2DM). Patients with T2DM who had completed the initial 24-week study comparing gemigliptin monotherapy with placebo were eligible to enrol. In the open-label, 28-week extension study, all enrolled patients received gemigliptin, regardless of the treatment received during the initial 24-week study period. The mean reduction±standard deviation (SD) in glycosylated hemoglobin (HbA1c) observed after 24 weeks of treatment (–0.6%±1.1%) was further decreased for the gemi-gemi group and the mean change in HbA1c at week 52 from baseline was –0.9%±1.2% (P<0.0001). For the pbo-gemi group, HbA1c decreased after they were switched to gemigliptin, and the mean change in HbA1c at week 52 from baseline was –0.7%±1.2% (P<0.0001). Furthermore, the overall incidence of adverse events demonstrated that gemigliptin was safe and well tolerated up to 52 weeks.

BACKGROUND: Combination of metformin to reduce the fasting plasma glucose level and an α-glucosidase inhibitor to decrease the postprandial glucose level is expected to generate a complementary effect. We compared the efficacy and safety of a fixed-dose combination of voglibose plus metformin (vogmet) with metformin monotherapy in drug-naïve newly-diagnosed type 2 diabetes mellitus. METHODS: A total of 187 eligible patients aged 20 to 70 years, with a glycosylated hemoglobin (HbA1c) level of 7.0% to 11.0%, were randomized into either vogmet or metformin treatments for 24 weeks. A change in the HbA1c level from baseline was measured at week 24. RESULTS: The reduction in the levels of HbA1c was −1.62%±0.07% in the vogmet group and −1.31%±0.07% in the metformin group (P=0.003), and significantly more vogmet-treated patients achieved the target HbA1c levels of <6.5% (P=0.002) or <7% (P=0.039). Glycemic variability was also significantly improved with vogmet treatment, estimated by M-values (P=0.004). Gastrointestinal adverse events and hypoglycemia (%) were numerically lower in the vogmet-treated group. Moreover, a significant weight loss was observed with vogmet treatment compared with metformin (−1.63 kg vs. −0.86 kg, P=0.039). CONCLUSION: Vogmet is a safe antihyperglycemic agent that controls blood glucose level effectively, yields weight loss, and is superior to metformin in terms of various key glycemic parameters without increasing the risk of hypoglycemia.

BACKGROUND: There has been controversy about predicting difficult LMA insertion and suboptimal position. Our aim was to evaluate bedside predictors for difficult LMA ProSeal(TM) (PLMA) insertion and suboptimal position. METHODS: As the potential predictive factors for difficult PLMA insertion and suboptimal position, we considered male gender, increased body mass index (BMI), seven individual items suggesting difficult airway [modified Mallampati classification > or = III, inter-incisor distance < or = 5 cm, thyromental distance < or = 6.5 cm, head/neck movement < or = 90degrees, history of difficult intubation, buck of teeth > or = moderate, upper lip bite test (ULBT) > or = II] and > or = 3 of total airway score which is the sum of scores assessed by a score of 0, 1, 2 in seven individual items. The PLMA position was assessed by fiberoptic bronchoscopy to determine whether these predictors predict suboptimal position of PLMA (fiberoptic score < 3, as graded on a standard fiberopitc scale). We also investigated the effect of predictive factors on the failure of the first insertion of PLMA and time required for successful Proseal LMA insertion on the first attempt. RESULTS: 154 patients were enrolled in the study. The total airway score did have a significant relationship with the fiberoptic findings. The male gender and ULBT I of investigated predictors did significantly correlate with failure on the first insertion of PLMA. We did not find any significant relationship between the predictive factors and PLMA insertion time on the first attempt. CONCLUSIONS: The male gender and ULBT I indicate difficult PLMA insertion, and the total airway score > or = 3 indicates suboptimal position of PLMA.

BACKGROUND: The Korean National Diabetes Program (KNDP) cohort study is performing an ongoing large-scale prospective multicenter investigation to discover the pathogenesis of type 2 diabetes in Korean patients. This study was performed to examine the prevalence of chronic complications in patients with type 2 diabetes among those registered in the KNDP cohort within the past 4 years. METHODS: This study was performed between June 2006 and September 2009 at 13 university hospitals and included 4,265 KNDP cohort participants. Among the participants, the crude prevalence of microvascular and macrovascular diseases of those checked for diabetes-related complications was determined, and the adjusted standard prevalence and standardization of the general population prevalence ratio (SPR) was estimated based on the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) population demographics. RESULTS: Among the KNDP registrants, 43.2% had hypertension, 34.8% had dyslipidemia, 10.8% had macrovascular disease, and 16.7% had microvascular disease. The SPR of the KNDP registrants was significantly higher than that of the KNHANES subjects after adjusting for demographics in the KNHANES 2005 population. However, with the exception of cardiovascular disease in females, the standardized prevalence for the most complicated items in the survey was significantly higher than that in the KNHANES subjects. CONCLUSION: The prevalence of macrovascular disease and peripheral vascular disease were significantly higher in Korean patients with type 2 diabetes than in the normal population. However, no significant difference was noted in the prevalence of cardiovascular disease in females.

OBJECTIVES: This study was done in adolescents with a high risk of substance or internet addiction in order to confirm the assumption that insecure attachment formation and impulsivity-inattention problems are major risk factors in adolescent addictive behavior. METHODS: 2,188 middle and high school students including a nicotine dependent treatment group were assessed using self-reporting scales : Adolescent Drinking Index (ADI), Fagerstrom Tolerance Questionnaire, Young Internet Addiction Scale, Revised Adult Attachment Scale (RAAS), and the Conner and Well's Self-reporting Scale for ADHD (CASS) were used. Subjects were classified into risk groups including substance addiction, internet addiction, as well as a combined group. RESULTS: Significant correlations were found between attachment formation and internet addiction tendencies, with respect to dependence, anxiety, and closeness (r=-0.185, r=0.248, r=-0.147, p<0.01, respectively). Impulsivity-inattention problems had positive correlations with internet addiction, alcohol addiction and nicotine addiction groups (r=0.345, r=0.211, r=0.187, p<0.01). With regard to attachment formation, the four groups showed significant differences regarding dependence (F=19.427, p<0.01), anxiety (F=28.926, p<0.01), and closeness (F=12.853, p<0.01). In addition, the four groups showed significant difference with respect to impulsivity-inattention problems (F=83.857, p<0.01), of which the combined risk group showed the highest scores, and the non-addicted group had the lowest scores. CONCLUSION: Insecure attachment formation and impulsivity-inattention problems were major risk factors for adolescent addictive behavior including internet addiction.

OBJECTIVES : We investigated the relationship between periventricular and deep white matter hyperintensity and cognitive function in Alzheimer's disease (AD) and mild cognitive impairment (MCI). METHODS : T2-weighted MRI scans were performed in 41 subjects with AD 38 subjects with mild cognitive impairment and 38 control subjects. Periventricular and deep white matter hyperintensities were rated on a Fazekas 0-3 scale by a medical specialist of the department of radiology blind to clinical diagnosis. Cognitive function was assessed by using Cognitive Assessment and Reference Diagnoses System. RESULTS : No significant differences between demographic characteristics and vascular risk factors were revealed comparing AD, MCI and controls. The frequencies of AD were significantly higher than those of MCI and normal control in Grade 2 and 3 of periventricular hyperintensity and Grade 3 of deep white matter hyperintensity. The scores of amnesia, executive function and attention were significantly lower in Grade 2 and 3 of periventricular hyperintensity than in Grade 0 and 1. The scores of attention were significantly lower in Grade 3 of deep white matter hyperintensity than in Grade 0, 1 and 2. CONCLUSION : Periventricualr hyperintensities are associated with cognitive decline in amnesia, executive function and attention, while deep white matter hyperintensities are associated with cognitive decline in attention.
