We have evaluated the effect of long term treatment of Enicostemma littorale (E. littorale) in type 2 diabetic patients taking pills of aqueous extract of E. littorale regularly as a complimentary medicine for at least 9 months. The effects of E. littorale on glycemic control, lipid profile, cardiac function and DNA damage in these patients were compared with those who had not been regular in taking E. littorale but regular in taking other conventional anti-diabetics. Our data suggest that, E. littorale can maintain normal blood glucose, serum insulin, serum triglycerides levels of type 2 diabetic patients if taken regularly. E. littorale also improves insulin sensitivity, and normalize disturbed lipogram and elevated creatinine levels, thereby produces beneficial effect in preventing cardiovascular complications and may preserve the kidney function. The finding that E. littorale also prevents DNA damage suggest a long term effect in diabetic patients. E. littorale thus can be considered as safe supplementary therapy for a long term and effective management of type 2 diabetic patients.

It is generally accepted that diet modification provides beneficial effects on the management of diabetes. In the present study, we evaluated the effects of diet modification on nutrient intake and quality of life in a large sample of diabetic patients. This study was conducted using data from the Korea National Health and Nutrition Examination Survey IV and V (2007-2010). A total of 2,484 of diabetic patients were included in the analysis. Then, we compared the overall quality of dietary intake between diabetic patients with diet modification and those without dietary modification. The result showed that subjects on diabetic diet (DDG) showed lower levels of total cholesterol, triglyceride, and AST before and after the adjustment for covariates (all p < 0.05). The results of nutrient assessment showed that DDG had lower intakes of total energy, fat, and carbohydrate (all p < 0.05), but higher intakes of energy from protein, vitamin B1, vitamin B2, niacin and vitamin C than NDG. (all p < 0.05). In addition, nutritional adequacy ratio of calcium and vitamin B2 were significantly higher in DDG than those in normal diet group (NDG) (p < 0.05). However, we observed no significant differences in quality of life between two groups. In conclusion, diet modification in diabetic patients seemed to be effective to improve blood lipid profile and the adequacy of nutrient intake without sacrificing the quality of life.

The number of diabetics in Korea is about 3 to 5 percent of the population, and the incidence is increasing yearly due to changes of life style and food intake. Diet is a key element in the management of diabetes, yet the appropriate diet for diabetes remains controversial. We have recently shown that a diet rich in protein of animal origin(casein) seems beneficial to controling plasma glucose and lipids in streptozotocin-induced diabetic rats. It therefore seemed desirable to find out whether the beneficial effect of high casein diet in experimental diabetes could also be reproduced with a vegetable source of protein(soy). The purpose of this study is to compare these results with the results of our previous study. In the present study, non-diabetic and streptozotocin-induced diabetic rats were studied in order to examine the effects of altering the level(20% vs 60%) of dietary soy protein on blood glucose, lipids, and hormones. Results of the present study showed that a high soy protein diet decreased triglyceride concentration in diabetic rats. However, diabetic rats fed a high soy protein diet were not hypocholesterolemic compared to rats fed a control diet. Moreover, diabetic rats fed a high soy protein diet had significantly increased plasma glucose concentration compared to rats fed a control diet. This study was not able to discern a specific effect of dietary protein level on insulin, glucagon, or insulin/glucagon ratio. Except for the hypotriglyceridemic effect, the results were not similar to the findings of our previous study which showed a beneficial effect on streptozotocin-induced diabetic rats fed a high casein diet.

Dolichos biflorus Linn. (Fabaceae), commonly known as Horse gram is a medicinal plant, used in folk medicine for treating kidney stones and diabetes mellitus. The purpose of the present study was to investigate the effects of daily oral feeding of various doses of methanolic extract of Dolichos biflorus seeds (DB) for 42 days on blood glucose concentrations and kidney functions in Alloxan-diabetic rats. Plasma glucose levels, body weight, serum creatinine, and urinary albumin levels were monitored on $15^{th}$, $29^{th}$, $43^{rd}$ day. Renal hypertrophy was assessed as the ratio between the kidney weight and body weight of the rats. Plasma glucose concentrations in Alloxan-diabetic rats were significantly reduced by the administration of DB (350 mg/kg) and DB (700 mg/kg) on day 15 and onwards (P < 0.01). After 15 days of Alloxan administration urinary albumin levels (UAE) were over 5 fold higher in diabetic controls as compared to normal controls. Treatment with DB significantly prevented the rise in UAE levels from day 15 to 43 in comparison to diabetic controls (P < 0.01). Renal hypertrophy was significantly higher in diabetic controls as compared to non-diabetic controls. Treatments with DB (350 mg/kg) and DB (700 mg/kg) significantly prevented renal hypertrophy (P < 0.01) as compared to diabetic controls. DB (175 mg/kg) failed to modify renal hypertrophy. Thus the present study indicates that methanolic extract of Dolichos biflorus may be useful in management of hyperglycemia and kidney functions in Alloxan-diabetic rats.

Methanol extracts of Commelina communis, a Korean wild edible plant showing hypoglycemic effect on diebetic rats were fractionated systematically by hexane, chloroform, butanol, and water, and these four fractions were administered orally to streptozotocin-induced diabetic rats to evaluate the hypoglycemic effect. The butanol and water fractions of Commelina communis lowered blood glucose levels of diebetic rats at a dose of 500 mg/kg/day. Administration of each fraction except that of chloroform increased the plasma protein levels. Liver protein levels were significantly higher in the butanol- and water fraction-fed groups. The results suggest that the butanol fraction of Commelina communis has hypoglycemic effect on diabetic rats and the intake of Commelina communis may be beneficial for the management of diabetes mellitus.

Diabetic retinopathy (DR) is a prevalent complication of diabetes that can lead to vision impairment if not diagnosed and treated promptly. This study presents a novel approach for the automated grading of diabetic retinopathy in ultra-widefield fundus images (UFI) using deep learning techniques. We propose a method that involves preprocessing UFIs by cropping the central region to focus on the most relevant information. Subsequently, we employ state-of-the-art deep learning models, including ResNet50, EfficientNetB3, and Xception, to perform DR grade classification. Our extensive experiments reveal that Xception outperforms the other models in terms of classification accuracy, sensitivity, and specificity. his research contributes to the development of automated tools that can assist healthcare professionals in early DR detection and management, thereby reducing the risk of vision loss among diabetic patients.

Purpose: The purpose of this study was to evaluate the surgical outcome of split-thickness skin graft (STSG) for chronic diabetic wounds of the foot and ankle. Materials and Methods: The medical records of 20 patients who underwent surgery for chronic diabetic wounds of the foot and ankle between October 2013 and May 2018 were reviewed. Surgical management consisted of consecutive debridement, followed by negative-pressure wound therapy and STSG. We used an acellular dermal matrix between the wound and the overlying STSG in some patients with wide or uneven wounds. Patient satisfaction, comorbidities, wound size and location, length of hospital stay, wound healing time, and complications were investigated. Results: Of 20 patients, 17 (85.0%) were satisfied with the surgical outcome. Eight patients had diabetic wounds associated with peripheral vascular disease (PVD), 7 patients had diabetic wounds without PVD, and 5 patients had acute infection superimposed with necrotizing abscesses. The mean size of the wound was 49.6 cm². The mean length of hospital stay was 33.3 days. The mean time to wound healing was 7.9 weeks. The mean follow-up period was 25.9 months. Complications included delayed wound healing (4 cases) and recurrence of the diabetic wounds (2 cases), which were resolved by meticulous wound dressing. Conclusion: STSG remains a good treatment strategy for chronic diabetic wounds of the foot and ankle.

Purpose: The purpose of this study was to test the effects of tailored diabetic education on blood glucose control and self-care for patients with type 2 diabetes on insulin therapy. Methods: The participants were 60 patients (experimental group: 30, control group: 30) with type 2 diabetes on insulin therapy. The patients were being seen at a university hospital in Seoul, Korea. Group diabetic education and tailored diabetic education were given to the experiment group while group diabetic education only was given to the control group. Data were collected before and three months after the education. $X^2$ test, t-test, and ANCOVA were used to analyze the data. Results: No significant differences in postprandial (PP2hrs) glucose and HbA1c levels were found between the two groups. Participants in the experiment group showed statistically significant differences in the area of self-glucose test, management of insulin injection, and life style change compared to those in the control group. Conclusion: The results indicate that tailored education for patients with diabetes on insulin therapy improve self-glucose test, management of insulin injection, and life style. Therefore it is suggested that tailored education can be applied in diabetic education to improve self-care.

Background: The purpose of this study was to investigate the estimated proportion for influenza vaccination and to identify factors associated with influenza vaccination in Korean diabetic patients. Methods: Data from the fourth, fifth, and sixth (except for 2013) Korea National Health and Nutrition Examination Survey (n=3,726) was used. A chi-square test was performed to investigate the estimated proportion for influenza vaccination, and a multiple logistic regression analysis was used to identify the factors associated with self-reported influenza vaccination. Results: In men, 28.8% of diabetes patients 30-64 years of age, and 76.1% of elderly (over 65 years of age) diabetes patients received influenza vaccination. In women, 37.7% of diabetes patients 30-64 years of age, and 78.4% of elderly diabetes patients received influenza vaccination (p<0.0001). The determinants of influenza vaccination were marriage, hypertension (odds ratio [OR], 1.55; 95% confidence interval [CI], 1.07-2.24), residence within a mega city, unemployment (OR, 3.94; 95% CI, 1.24-12.54), and exercise via (weekly) walking for diabetic men; and hypertension (OR, 1.71; 95% CI, 1.16-2.52), chronic disease (OR, 1.81; 95% CI, 1.08-3.02), and exercise via walking (OR, 2.65; 95% CI, 1.49-4.73) for diabetic women. Conclusion: Influenza vaccination remains relatively low in young diabetic patients. It is necessary to recommend vaccination to young diabetic patients, and to devise other strategies to improve vaccination.

Some patients tend to visit tertiary hospitals instead of non-tertiary hospitals for minor illnesses, which is a chronic problem within the Korean health care delivery system. In order to reduce the number of patients with minor severity diseases unnecessarily utilizing the tertiary medical services in Korea, the Ministry of Health and Welfare raised the outpatient co-insurance rate for the tertiary hospitals in July, 2009. Another increase in the prescription drug co-insurance rate by the general and tertiary hospitals is scheduled to take place in the second half of 2011. An increase in copayments may discourage the utilization rate of medical services among the underprivileged or patients who require complicated procedures. This study aims to analyze the diabetic patients' utilization rates of tertiary hospitals according to the Comorbidity score. Diabetic patients' data was gathered from the Health Insurance Claims Records in the Health Insurance Review & Assessment Service between 2007-2009. Comorbidity scores are measured by the Charlson Comorbidity Index and the Elixhauser Index. Chi-square and logistic regressions were performed to compare the utilization rates of both insulin-dependents (n=94,026) and non-insulin-dependents (n=1,424,736) in tertiary hospitals. The higher Comorbidity outcomes in the insulin-dependent diabetic patients who didn't visit tertiary hospitals compared to those who did, was expected. However, after adjusting the gender, age, location, first visits and complications, the groups that scored >=1 on the comorbidity scale utilized the tertiary hospitals more than the O score group. Non-insulin-diabetic patients with higher Comorbidity scores visited tertiary hospitals more than patients who received lower grades. This study found that patients suffering from severe diabetes tend to frequently visit the tertiary hospitals in Korea. This result implied that it is important for Korea to improve the quality of its primary health care as well as to consider a co-insurance rate increase.
