Purpose: This study investigated the incidence and risk factors of cataract in people with diabetes mellitus (DM) using data from Ansan cohort of the Korean Genome and Epidemiology Study (KoGES). Methods: Data from a total of 329 patients with type 2 DM without cataract who participated in Ansan cohort of the KoGES from baseline survey (2001-2002) to fifth follow-up visit (2011-2012) were examined. The characteristics of the subjects were analyzed with frequency and percentage, and mean and standard deviation. Cataract incidence was measured as incidence proportion (%). For risk factors of cataract, hazard ratio (HR) and 95% confidence interval (CI) were obtained using the Cox proportional hazard model. Results: The cataract incidence over a 10-year follow-up period was 19.1% (15.1 in males and 25.8 in females), and mean age at the incidence of cataract was 63.48 years (61.58 years in males and 65.31 years in females). Age (HR=1.09, 95% CI=1.05-1.13) and HbA1c (HR=1.21, 95% CI=1.07-1.37) or the duration of DM (HR=1.05, 95% CI=1.00-1.09) were found to be independently associated with cataract development. Conclusion: Cataract development in people with DM is common, and its likelihood increases with age, HbA1c, and the duration of DM. Considering negative effect of cataract on their quality of life and economic burden, nurses should identify people with DM at a higher risk of cataract development, and plan individual eye examination programs to detect cataract development as early as possible.

Purpose: The purpose of this study was to investigate the knowledge of diabetes and insulin use in patients with type 2 diabetes. Method: Participants (139) were recruited from the endocrinology outpatient department of a tertiary care hospital in an urban city. Knowledge of diabetes knowledge was measured by a brief diabetes knowledge test which had two components: a 14-item general test and a 9-item insulin-use subscale. Result: The average scores for knowledge of diabetes and insulin were 62.4 and 41.8 respectively. Scores were lower for items on the definition of glycosylated hemoglobin, diabetic diet, signs of ketoacidosis, and insulin reaction compared to other items. Knowledge scores were significantly lower for older participants, those who had lower levels of education, those who did not have a spouse, those who did not have a job, those who were not being treated with insulin, and those who tested their blood glucose less than 3 times a day. Conclusion: Definition of glycosylated hemoglobin, diabetic diet, signs of ketoacidosis, and insulin reaction should be included in education for patients with type 2 diabetes. Special education programs should be developed for elderly people, those with low levels of education those without a spouse, or without a job, or who are not being treated with insulin.

This study was designed to evaluate the antidiabetic effect of mulberry fruits using insulin-dependent and/or non-insulin-dependent diabetes mellitus animal models. The administration of mulberry fruit did not affect either body wight or blood glucose level in the normal ICR mice and streptozotocin induced-type I diabetic mice group. In second experiment, prolonged mulberry fruits treatment did not significantly attenuate the blood glucose level in type I diabetes induced by streptozotocin. In third experiment, the antidiabetic effect of mulberry fruits have been investigated using type II diabetes animal model that was induced by administration of streptozotocin to 2-day-old rats. Significant decrease in blood glucose level was observed in prolonged mulberry fruits treated group. In these treated group, the weight of liver significantly decreased than that of control group. In fourth experiment using KK mice showing genetical type II diabetes mellitus, glucose tolerance has been significantly recovered in mulberry fruits treated group but not in control group. In conclusion, prolonged administration of mulberry fruits significantly reduced the blood glucose level in type II diabetic animals. However, the blood glucose level was not significantly reduced by prolonged mulberry treatment. These data suggest that mulberry fruits can be developed as functional food that has effect on the insulin-independent diabetus mellitus(type II daibetus mellitus).

Abnormal inflammatory responses are closely associated with intestinal microbial dysbiosis. Oral administration of Qmatrix-diabetes-mellitus complex (QDMC), an Aloe gel-based formula, has been reported to improve inflammation in type 2 diabetic mice; however, the role of the gut microbiota in ameliorating efficacy of QDMC remains unclear. We investigated the effect of QDMC on the gut microbiota in a type 2 diabetic aged mouse model that was administered a high-fat diet. Proinflammatory (TNF-α and IL-6) and anti-inflammatory (IL-4 and IL-10) cytokine levels in the fat were normalized via oral administration of QDMC, and relative abundances of Bacteroides, Butyricimonas, Ruminococcus, and Mucispirillum were simultaneously significantly increased. The abundance of these bacteria was correlated to the expression levels of cytokines. Our findings suggest that the immunomodulatory activity of QDMC is partly mediated by the altered gut microbiota composition.

BACKGROUND/OBJECTIVES: This prospective study examined gender-specific associations between egg intake and the risk of developing type 2 diabetes using data from a large-scale cohort study. SUBJECTS/METHODS: A total of 7,002 Korean adults (40-69 years) without type 2 diabetes at baseline were analyzed. Dietary intake was evaluated by a food frequency questionnaire administered at baseline (2001-2002) and the second follow-up examination (2005-2006). Type 2 diabetes was diagnosed as a fasting glucose concentration ${\geq}126mg/dL$ or current use of glucose-lowering medications or insulin injection. Multivariate Cox proportional hazard models were used to calculate hazard ratios (HRs) with 95% confidence intervals (CIs) for incident type 2 diabetes according to egg consumption or cholesterol intake. RESULTS: During a 14-year follow up period, 857 subjects developed type 2 diabetes. In men, frequent egg intake (2- < 4 servings/week) was associated with a 40% lower risk of developing type 2 diabetes than infrequent egg intake (0- < 1 serving/week) (HR = 0.60, 95% CI: 0.37-0.97), whereas no association between egg intake and incidence of type 2 diabetes was observed in women (HR = 0.61, 95% CI: 0.27-1.37). There was no association between cholesterol intake and risk of incident type 2 diabetes in either men or women. CONCLUSIONS: Egg consumption was inversely related to the risk of incident type 2 diabetes in men, but not in women, suggesting gender differences in the relationship between diet and disease risk.

Purpose: This study aimed to analyze the content and effectiveness of psychosocial support interventions for women with gestational diabetes mellitus (GDM). Methods: The following databases were searched with no limitation of the time period: Ovid-MEDLINE, Cochrane Library, Ovid-Embase, CINAHL, PsycINFO, NDSL, KoreaMed, RISS, and KISS. Two investigators independently reviewed and selected articles according to the predefined inclusion/exclusion criteria. ROB 2.0 and the RoBANS 2.0 checklist were used to evaluate study quality. Results: Based on the 14 selected studies, psychosocial support interventions were provided for the purpose of (1) informational support (including GDM and diabetes mellitus information; how to manage diet, exercise, stress, blood glucose, and weight; postpartum management; and prevention of type 2 diabetes mellitus); (2) self-management motivation (setting goals for diet and exercise management, glucose monitoring, and enhancing positive health behaviors); (3) relaxation (practicing breathing and/or meditation); and (4) emotional support (sharing opinions and support). Psychosocial supportive interventions to women with GDM lead to behavioral change, mostly in the form of self-care behavior; they also reduce depression, anxiety and stress, and have an impact on improving self-efficacy. These interventions contribute to lowering physiological parameters such as fasting plasma glucose, glycated hemoglobin, and 2-hour postprandial glucose levels. Conclusion: Psychosocial supportive interventions can indeed positively affect self-care behaviors, lifestyle changes, and physiological parameters in women with GDM. Nurses can play a pivotal role in integrative management and can streamline the care for women with GDM during pregnancy and following birth, especially through psychosocial support interventions.

The study investigated medical treatment features of patients with type 2 diabetes mellitus, their further complications, levels of diet therapy education and the status of dietary compliance. The subjects were patients who came to oriental medicine clinics in Daejon. The percentage of male was 37.5% and female was 62.7% in the subject group's sex distribution. The outbreak of the disease was most common in the age of 50's. Also 40% of the subjects had been suffering for more than 5 years. 35.7% of men and 53.7% of women had family history. All the subjects had further complications, among them hypertension was the most common. Kidney, hepatic, vascular heart diseases were followed. 85.3% of the subjects answered they already had educations about diet therapy. Those educations were given in the public health center, general and private hospitals. 32% of subjects were not practicing diet therapy. The difficulties with which patients can be faced when they take dietary education were exchange(?exchanging?) food and calculating calories. Most of the subjects tend to overlook the importance of dietary habits and show low understanding to diet therapy, which leads to low participation rate of diabetes patients. Based on these results, therefore, we can conclude that diet therapy education to the patients should be more organized and easily practicable for them. To develop educational methods which can draw patients' attention and also be more effective is the most important task.

There is a lack of evidence on the impact of pharmacist interventions in diabetes care in South Korea. The aim of this study was to investigate the effects of pharmacist counseling on clinical and humanistic outcomes in patients with type 2 diabetes. An uncontrolled before-and-after study was conducted at the outpatient diabetes clinic in a teaching hospital in Gyeongnam, South Korea between January 2 and November 30, 2014. A total of 37 patients were enrolled. During the study periods, the participants and pharmacists met every 2 weeks via follow-up telephone calls in addition to face-to-face meetings upon returning for care visit. At each meeting, a structured patient counseling was performed and the average duration of each meeting was 15~30 minutes. The participants were requested to record daily self-care activities. At the end of this study, patients' satisfaction on pharmacist care was evaluated using the questionnaire developed by us. Compared to baseline, significant reductions (mean${\pm}$standard deviation, p<0.05) in HbA1c were observed at each follow-up period: $-0.32{\pm}0.72%$ from baseline to 3 months; $-0.52{\pm}0.76%$ from baseline to 6 months; $-0.72{\pm}0.76%$ from baseline to 9 months. Over the same follow-up period, the proportions of patients achieving target HbA1c (defined as HbA1c<6.5%) were 3.1%, 10.3%, and 20%, respectively. The proportions of patients who never missed a dose during the same follow-up period were 43.8%, 31.0%, and 20.0%, respectively. The results from the patient satisfaction survey indicated that pharmacist counseling improved patients' knowledge about diabetes and possible drug interactions. Especially, the information on a healthy diet and lifestyle was the most satisfying. To conclude, follow-up telephone calls combined with face-to-face meetings improved clinical and humanistic outcomes in patients with type 2 diabetes mellitus.

To control blood glucose level as close to normal is a major goal of treatment of diabetes mellitus. Hyperglycemia and hyperlipidemia are the major risk factors for cardiovascular complications, the major cause of immature death among the patients with type 2 diabetes. The purpose of this study is to determine the hypoglycemic and hypolipidemic effects of Salicornia herbacea in animal model of type 2 diabetes and to investigate the possible mechanisms for the beneficial effects of S. herbacea. S. herbacea was extracted with 70% ethanol and desalted with 100% ethanol. Three week-old db/db mice (C57BL/KsJ, n=16) were fed AIN-93G semipurified diet or diet containing 1% desalted ethanol extract of S. herbacea for 6 weeks after 1 week of adaptation. Fasting plasma glucose, triglyceride, and total cholesterol were measured by enzymatic methods and blood glycated hemoglobin ($HbA_{1C}$) by the chromatographic method. Body weight and food intake of S. herbacea group were not significantly different from those of the control group. Fasting plasma glucose and blood glycated hemoglobin levels tended to be lowered by S. herbacea treatment. Consumption of S. herbacea extract significantly decreased plasma triglyceride and cholesterol levels (p<0.05). The inhibition of S. herbacea extract against yeast ${\alpha}$-glucosidase was 31.9% of that of acarbose at the concentration of 0.5 mg/mL in vitro. The inhibitory activity of ethanol extract of S. herbacea against porcine pancreatic lipase was 59.0% of that of orlistat at the concentration of 0.25 mg/mL in vitro. Thus, these results suggest that S. herbacea could be effective in controlling hyperlipidemia by inhibition of pancreatic lipase in animal model of type 2 diabetes.
