Objectives : A growing body of evidence links type 2 diabetes (T2D) with a neurodegenerative disease (ND) such as Alzheimer's disease and Parkinson's disease. The purpose of this study is to investigate the relationship between NDs and the development of T2D by comparing the incidence of T2D in a group of various NDs (ND group) and control group. Methods : A population-based 10-year follow-up study was conducted using the Korean National Health Information Database for 2002-2015. We used a retrospective cohort study design to investigate the association of ND with T2D occurrence. The study population included ND (n=8,814) and control (n=37,970) groups, all aged 60 years or over. The Kaplan-Meier method was used to estimate the risk of developing T2D as a function of time. Cox proportional hazards regression models were used to evaluate the relationship between ND and T2D. Results : T2D was developed in a significantly higher percentage of patients in the ND group (53.6%) than in the control group (44.7%). The ND group increased the risk of T2D (HR, 1.43; 95% CI, 1.38-1.47). About one-third of patients in both groups were additionally diagnosed with another ND before the occurrence of T2D during a 10-year follow-up period. When compared to those who did not have another ND during the follow-up period, the incidence of T2D in those who were additionally diagnosed with another ND was higher in both the ND and control groups. Conclusions : The ND group had about 1.4 times higher risk of developing T2D than the control group. Our results showed a positive association between ND and T2D.

This study was performed to investigate the antihyperglycemic effect of green tea extracts (GTE) in diabetic rats. Experimental animals used were alloxan-induced diabetic Sprague-Dawley (SD) rats; as a model of type 1 diabetes mellitus and Otsuka Long Evans Tokushima fatty (OLETF) rats, and as a model of type 2 diabetes mellitus. Animals were randomly assigned either to continue the ad libitum diet or begin a green tea extracts (GTE) contained diet. GTE extracted from green tea was supplemented in the diet (2%). Body weight, food intake, and blood glucose concentration were recorded for 4 weeks. Animals were killed and glucose, triglyceride, and asparate aminotransferase (AST) were analysed in blood. Food intake was not affected by GTE in both alloxan.induced diabetic and OLETF rats but body weight was slightly decreased by GTE in OLETF rats. The blood glucose concentration was markedly decreased by GTE supplementation in both alloxan-induced diabetic and OLETF rats; however, triglyceride and AST levels in serum of GTE treated animals were not changed. This study shows that GTE beneficially modulate blood glucose concentration in diabetic animals. Dietary supplementation with GTE could potentially contribute to nutritional strategies for the treatment of diabetes mellitus.

Today, the environment in which type 1 Diabetes children learn how to cope with their Diabetes is very vulnerable. Therefore, it is necessary to create an environment that can respond to changes in blood sugar level of children. The purpose of this study is to suggest game-based educational content on how to deal with changes in blood sugar level through behavioral methods for children with type 1 Diabetes. The purpose of this study is to suggest education type game contents using hybrid method which enhances efficiency in learning children 's expert knowledge. Based on the results of the interviews conducted with diabetes specialists for this study, we suggested the contents of coping with blood sugar change composed of education contents required for the children. As a result of this study, it was found that the hybrid factor was useful in learning diabetes through games. These game contents are expected to provide an environment that children with diabetes can learn more efficiently.

The purpose of this study was to examine the effects of aerobic and resistance exercise of different intensity on anti-diabetic and lipid profile improvement in type 2 diabetic mice. C57BL/6 mice were divided into six groups (n=8, in each group): normal group (Normal), type 2 diabetes (DM), type 2 diabetes+VO₂max 50% aerobic exercise group (DM50A), type 2 diabetes+VO₂max 75% aerobic exercise group (DM75A), type 2 diabetes+1RM 50% resistance exercise group (DM50R), and type 2 diabetes+1RM 75% resistance group (DM75R). DM50A and DM75A were subjected to treadmill exercise 40 min/day, 5 days/week, during 8 weeks (DM50A, at the speed of 8 m/min for 1-4 weeks and 8~10 m/min for 5-8 weeks; DM75A, 12 m/min for 1-4 weeks and 12~14 m/min for 5-8weeks). DM50R (1RM50%) and DM75R (1RM75%) were subjected to ladder-climbing exercise with weights secured to their tails, 8 set/day, 5 days/week, during 8 weeks. After 8 weeks of exercise, fasting blood glucose and HOMA-IR was significantly lower in DM group than in DM group. HbA1c showed significantly lower DM50R and DM75R groups than DM group. HDL-C showed the highest level in DM75A group and triglyceride was lowest in DM75R group. The cardiovascular risk index was lowest in the Normal and DM75A groups. Therefore, moderate intensity exercise in T2DM mice showed better improvement in blood glucose and insulin resistance control, and moderate intensity aerobic exercise was effective in reducing the cardiovascular risk index by increasing HDL-C levels.

Objectives : Many of the patients with type 2 diabetes are associated with sleep problems, and the rate of insomnia is known to be higher in the general population. The aims of this study were to know the frequency and clnical characteristics of insomnia, and related variables to insomnia in patients diagnosed with type 2 diabetes. Methods : For 99 patients from 18 to 80 years of age (65 males and 34 females) with type 2 diabetes, interviews were performed. Total sleep time and sleep latency was evaluated. Insomnia was evaluated using the Korean Version of the Insomnia Severity Index (ISI-K). Severity of depressive symptoms were evaluted using the Korean version of the Hamilton Depression Scale (K-HDRM). According to the cutoff score of 15.5 on the ISI-K, subjects were divided into the group of type 2 diabetics with insomnia (N=34) and those without insomnia (N=65) at first, and then statistically analyzed. Results : TInsomnia could be found in 34.34% of type 2 diabetics. Type 2 diabetics with insomnia had significantly more single or divorced (respectively 11.8%, p<0.05), higher total scores of the K-HDRS ($11.76{\pm}5.52$, p<0.001), shorter total sleep time ($5.35{\pm}2.00hours$, p<0.001), and longer sleep latency ($50.29{\pm}33.80minutes$, p<0.001). The all item scores of the ISI-K in type 2 diabetics with insomnia were significantly higher than those in type 2 diabetics without insomnia, that is, total ($18.38{\pm}2.69$), A1 (Initial insomnia) ($2.97{\pm}0.76$), A2 (Middle insomnia) ($3.06{\pm}0.69$), A3 (Terminal insomnia) ($2.76{\pm}0.61$), B (Satisfaction) ($3.18{\pm}0.72$), C (Interference) ($2.09{\pm}0.97$), D (Noticeability) ($2.12{\pm}1.09$) and E (Distress) ($2.21{\pm}0.81$) (respectively p<0.001). Variables associated with insomnia in type 2 diabetics were as following. Age had significant negative correlation with A3 items of the ISI-K (${\beta}=-0.241$, p<0.05). Total scores of the K-HDRS had significant positive correlation, while total sleep time had significant negative correlation with all items of the ISI-K (respectively p<0.05). Sleep latency had significant positive correlation with total,, A1, B and E item scores of the ISI-K (respectively p<0.05). Conclusions : Insomnia was found in about 1/3 of type 2 diabetics. According to the presence of insomnia, clinical characteristics including sleep quality as well as quantity seemed to be different. Because depression seemed to be correlated with insomnia, clinicians should pay attention to early detection and intervention of depression among type 2 diabetics.
