The purpose of this study was to confirm if self-management and self-efficacy of diabetic nephropathy hemodialysis patients were influencing factors on the hemodialysis-related symptoms. A cross-sectional study was performed on 254 patients based at 3 University hospital hemodialysis centers and 7 hemodialysis clinics from September 2017 to November 2017. The data was analyzed using t-test, ANOVA, Scheffe test, Pearson correlation, and multiple regression analysis. The results showed that patients with stable economic condition and no complications from diabetes, the higher patient self-management and self-efficacy led to lower hemodialysis related symptoms. Therefore, the government should provide financial support, a management process needs to be set up to prevent complications from diabetes, and disease-specific patient self-management program should be implemented to increase patient's self-efficacy.

Objectives : The object of this study was to observe the effects of Hwangryungeehwang-tang (HRGHT), which has traditionally been used in Korean medicine for treating diabetes, by administering aqueous extracts to streptozotocin-induced diabetic rats. Methods : Three different dosages of HRGHT extracts were orally administered once a day for 28 days from 3 weeks after streptozotocin treatment (60 mg/kg, single intraperitoneally administered). 6 groups, of 8 rats per group were used in the present study, selected 3 weeks after streptozotocin treatment based on blood glucose levels and body weights. Changes to the body weights, blood glucose levels, serum low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride and total cholesterol levels were observed, as well as changes on the pancreatic, hepatic and kidney malondialdehyde (MDA) contents for lipid peroxidation and glutathione contents for antioxidant effects. The results were compared with a potent antioxidant silymarin 100 mg/kg, of which the effects on streptozotocin-induced diabetes and related complications are already confirmed. Results : Significant decrease of blood glucose levels, serum LDL, total cholesterol, triglyceride levels, pancreatic, hepatic and renal MDA contents and significant increase of body weights, serum HDL levels, pancreatic, hepatic and renal GSH contents were detected in HRGHT extracts 100 and 200 mg/kg administered groups as compared to the streptozotocin control group. The lowest dosage of HRGHT treated group, 50 mg/kg, did not show any favorable effects as compared with the streptozotocin control. Conclusions : HRGHT has favorable effects on diabetes and related hyperlipidemia. Therefore, more detailed mechanism studies should be conduced in future with efficacy tests of individual herbal compositions of HRGHT and screening of the biological active compounds in the herbs.

Diabetes mellitus can cause devastating complications, which often result in disability and death, and diabetic nephropathy is a leading cause of death in people with diabetes. In this study, we tried to predict the onset of diabetic nephropathy from an irregular and unbalanced diabetic dataset. We collected clinical data from 292 patients with type 2 diabetes and performed preprocessing to extract 184 features to resolve the irregularity of the dataset. We compared several feature selection methods, such as ReliefF and sensitivity analysis, to remove redundant features and improve the classification performance. We also compared learning methods with support vector machine, such as equal cost learning and cost-sensitive learning to tackle the unbalanced problem in the dataset. The best classifier with the 39 selected features gave 0.969 of the area under the curve by receiver operation characteristics analysis, which represents that our method can predict diabetic nephropathy with high generalization performance from an irregular and unbalanced dataset, and physicians can benefit from it for predicting diabetic nephropathy.

Objectives: The purpose of this study is to analyze the proportion of fundus examination of DM patients for preventing microvascular complication and to examine the factors related to fundus examination in DM patients. Methods: This study used 2005 Korean national health and nutrition survey data. We selected all 1,129 diabetes mellitus patients from the data. And we choose 8 factors related to diabetes mellitus patients. These are sex, age group, type of residential area(rural or urban), education level, income level, comorbidity with hypertension, current insulin use, and duration of suffering from DM. We have analysed these factors by whether he had been examined fundus or no through Chi-square and logistic regression analysis. Results: Female DM patients have tendency to get more fundus examination than Male DM patients. And Young patients, patients who live in urban area, well educated patients, high income patients, comorbidity with hypertension, patients have got the insulin injection, patients have long duration of suffering from DM are to get more fundus examination. According to multivariate logistic regression analysis, sex and education level, income level, and duration of suffering from DM, comorbidity with hypertension, patients have got the insulin injection are significant factors on fundus examination for prevent microvascular diabetes mellitus complications. Conclusions and Discussion: We have concluded that physicians and policy makers should consider to fundus examination especially of man and DM patients who have more shorter disease period and low educated patients and low incomed patients and patients who have taken insulin therapy.

The present study was conducted to document the association between plasma homocysteine levels and the presence of macrovascular angiopathy with food and nutrient intake patterns among patients with Type II diabetes mellitus in Korea. Plasma total homocysteine concentration was analyzed by HPLC-fluorescence detector method in 127 patients with non-insulin dependent diabetes mellitus. Logistic regression analyses were performed respectively to study the association of plasma homocysteine levels with clinical and dietary characteristics and macroangiopathy (MA). The average plasma homocysteine level of patients with MA was $14.2{\mu}mol/l$, which was significantly higher than that of patients without MA ($11.4{\mu}mol/l$). The proportions of patients with MA showed a significant difference, being 32.3% in hyperhomocysteinemic ($>14.0{\mu}mol/l$) patients and 13.5% in others with homocysteine levels lower than $14.0{\mu}mol/l$. Odds ratios for macroangiopathy by tertile increase of plasma homocysteine concentration were 1.633 ($Q_2$) and 4.831 ($Q_3$), when adjusted for age, sex, and cigarette smoking. Patients with MA consumed reduced amounts of vitamin $B_1,\;B_2$, and folate. The results indicate that the plasma homocysteine levels are significantly increased in NIDDM patients who have macroangiopathy. Dietary management such as increased fruits and vegetables and decreased potatoes and starches might be beneficial for the prevention of macroangiopathy in diabetic patients.

Hepatic glycogenosis in type 1 diabetes mellitus (DM) can be caused by poor glycemic control due to insulin deficiency, excessive insulin treatment for diabetic ketoacidosis, or excessive glucose administration to control hypoglycemia. Mauriac syndrome, which is characterized by hepatomegaly due to hepatic glycogenosis, growth retardation, delayed puberty, and Cushingoid features, is a rare diabetic complication. We report a case of hepatic glycogenosis mimicking Mauriac syndrome. A 14-year-old girl with poorly controlled type 1 DM was admitted to The Catholic University of Korea, Seoul St. Mary's Hospital for abdominal pain and distension. Physical examination revealed hepatomegaly and a Cushingoid face. The growth rate of the patient had decreased, and she had not yet experienced menarche. Laboratory findings revealed elevated liver enzyme levels. A liver biopsy confirmed hepatic glycogenosis. Continuous glucose monitoring showed hyperglycemia after meals and frequent hypoglycemia before meals. To control hyperglycemia, we increased insulin dosage by using an insulin pump. In addition, we prescribed uncooked cornstarch to prevent hypoglycemia. After strict blood glucose control, the patient's liver functions and size normalized. The patient subsequently underwent menarche. Hepatic glycogenosis is a complication of type 1 DM that is reversible with appropriate glycemic control.

Purpose: Mucormycosis generally occurs in patients with uncontrolled diabetes mellitus and immunocompromised conditions. It is rare, but once a patient is infected with it, it can occur as a rapidly extending, aggressive, and life-threatening rhinocerebral infection with a high mortality rate. Methods: A 70-year-old female patient had a 40 years of history of adult onset diabetes mellitus. She presented herself with severe right hemifacial pain, swelling, and weakness for 3 days and was admitted to ENT. On a facial computed tomography (CT) scan, it was found that her infection extended from her inferior temporal scalp to her submental area and involved her submandibular, masseter, prevertebral, parapharyngeal, retropharyngeal, and pharyngeal mucosal space and pansinusitis. Through endoscopic sinus surgery, mucormycosis was confirmed via histologic examination. Results: Despite empiric antibiotics and amphotericin B administration, the patient was in a septic condition and in a coma. The patient's family wanted to withdraw her life support, and the patient expired. Conclusion: Mucormycosis is very rare, but is one of the disastrous complications of uncontrolled diabetes mellitus. Suspicion of its occurrence, based on identified risk factors, and its rapid diagnosis can enhance the chance of its cure.

The purpose of the present study was to examine effect of 12 week regular aerobic exercise on ST-segment and QTc interval in middle age type 2 diabetes mellitus (T2DM) patients. The subjects consist of 13 type 2 diabetes mellitus (T2DM) patients in middle age men and all of them had no other complications. Subjects participated in aerobic exercise training for 12 weeks. They started to exercise for $20{\sim}60$ min at $60{\sim}80%$ of $HR_{max}$, (exercise intensity has been increased gradually) per day, $3{\sim}5$ times a week. The results were compared before and after. Weight and BMI, % body fat, fasting glucose, HOMA-IR, $_{peak}DBP$ were significantly decreased and $_{peak}HR$, $_{peak}VO_2$, exercisre time were significantly increased after 12 week aerobic exercise. Also, QTc interval and ST-segment were significantly decreased during at rest, peak exercise after 12 week aerobic exercise. Conclusionally, 12 week aerobic exercise may be improvement in decreased cardiovascular mortality factors (ST-segment) and abnormal autonomic dysfunction (QTc interval) and potentially increased exercise capacity.

Objective: Diabetes mellitus (DM) is known to cause many systemic complications as well as male infertility. Astaxanthin (ASTX) is a powerful antioxidant that is involved in a variety of biologically active processes, including those with anti-diabetes effects. The present study investigates the effect of ASTX on the spermatozoa function in streptozotocin (STZ)-induced diabetic rats. Methods: We divided 30 adult rats into three groups (10 rats per group), with a control group that received corn oil mixed with chow. DM was induced by intra-peritoneal injection of STZ. Eight weeks after the STZ injection, half of the diabetic animals were used as diabetic controls, and the rest were treated with ASTX for 56 days. Then the parameters and chromatin integrity of the epididymal sperm were analyzed using chromomycin A3, toluidine blue (TB), and acridine orange (AO) staining. Results: The count, viability, and motility of the epididymal sperm were decreased significantly in the STZ group in comparison with the control group (count and viability, p<0.001; motility, p<0.01). ASTX increased normal morphology and viable spermatozoa compared to the STZ group (morphology, p=0.001; viability, p<0.05). The percentage of abnormal chromatins in TB and AO staining was higher in the STZ group compared to the control group (p<0.001). The mean percentage of TB and AO positive spermatozoa in STZ rats was significantly lower in the STZ+ASTX group (TB, p=0.001; AO, p<0.05). Conclusion: This study observed that in vivo ASTX treatment partially attenuates some detrimental effect of diabetes. Conversely, ASTX improved sperm viability, normal morphology, and DNA integrity.
